Abstract:
Objective: To evaluate the efficacy of surgical management for isthmoceles in patients presenting with secondary infertility.

Data Sources: A systematic search was performed in MEDLINE, EMBASE, and Cochrane Library databases from inception to May 2020. The search was limited to studies published in English. METHODS OF Study Selection: After the removal of duplicates, 3380 articles were screened for inclusion independently by 2 authors. These 2 authors assessed for studies which focused on women of reproductive age with a diagnosed isthmocele and secondary infertility who underwent any surgical intervention for defect repair with at least 1 of the goals being fertility restoration. TABULATION, INTEGRATION, AND

Results: A total of 13 studies, comprising of 1 randomized controlled trial, 6 prospective case series, and 6 retrospective case series describing 234 patients who underwent surgical management for an isthmocele and secondary infertility were included. The methodologic quality of the included studies was assessed independently by both reviewers. Next, the data extraction was performed independently and then compared to ensure no discrepancies. A total of 188 patients were treated by hysteroscopy, 36 by laparoscopy, 7 by laparotomy, and 3 through a vaginal approach. In total, 153 of the 234 patients (65.4%) achieved pregnancy across all studies within their respective study periods. Pregnancy rates in the randomized controlled trial were 21 of 28 (75%) for those treated by hysteroscopy compared with 9 of 28 (32%) for those untreated. Among the studies reporting pregnancy outcomes, 101 of 116 (87.1%) pregnancies resulted in a live birth. The incidence of adverse events was 2%, including the risk of reoperation.

Conclusion: The results of this systematic review suggest that the surgical treatment of an isthmocele, particularly through hysteroscopy, in patients with residual myometrial thickness of at least 2.5 mm, may be effective in treating isthmocele-associated secondary infertility with a relatively low complication rate. Further high-quality studies are needed because of the small sample sizes and observational nature of most available data.

Abstract: Alzheimer's disease is the most common neurodegenerative disease associated with deposition of amyloid-beta and the increased oxidative stress. High free radical scavenging ability of selenium nanoparticles (SeNPs) has been acknowledged, so in the present study, the effects of treatment with SeNPs on Streptozotocin (STZ)-induced neurotoxicity were evaluated in the male rats. Learning and memory impairment was induced by intraventricular injection of STZ. Following induction of memory impairment, the rats received 0.4 mg/kg of SeNPs daily for one month. Memory function, antioxidant capacity, and deposition of Amyloid β (Aβ) were assessed using the shuttle box task, biochemical methods, and Congo red staining. Injection of STZ caused memory impairment, a decrease in the level of total thiol group (TTG), and an increase in the malondialdehyde (MDA) content and deposition of Aβ. Administration of SeNPs reversed the neurotoxicity induced by STZ. It seems that SeNPs likely had neuroprotective effects on the animal model of Alzheimer's disease through increasing antioxidants҆ capacity.


Contemporary hormonal contraception and cervical cancer in women of reproductive  age

Abstract: To determine cervical cancer risk associated with contemporary hormonal contraceptives, we conducted a cohort study of women aged 15 to 49 living in Denmark from 1995 to 2014, using routinely collected information about redeemed prescriptions, incident cancer and potential confounders. Poisson regression calculated adjusted cervical cancer risks among different contraceptive user groups by duration of use, time since last use, hormonal content and cancer histology. During >20 million person-years, 3643 incident cervical cancers occurred. Ever users of any hormonal contraceptives compared to never users had a relative risk (RR) of 1.19 (95% confidence interval [CI] 1.10-1.29). Increased risks were seen in current or recent users of any hormonal: RR 1.30 (95% CI 1.20-1.42) and combined: RR 1.40 (95% CI 1.28-1.53), but not progestin-only contraception: RR 0.91 (95% CI 0.78-1.07). Current or recent users of any hormonal contraception had an increased risk of both adenocarcinoma (RR 1.29, 95% CI 1.05-1.60) and squamous cancer (RR 1.31, 95% CI 1.19-1.44). The risk pattern among any hormonal and combined contraceptive users generally increased with longer duration of use and declined after stopping, possibly taking longer to disappear among prolonged users. Combined products containing different progestins had similar risks. Approximately one extra cervical cancer occurred for every 14 700 women using combined contraceptives for 1 year. Most women in our study were not vaccinated against human papillomavirus (HPV) infections. Our findings reinforce the urgent need for global interventions such as systematic screening, treatment of cervical intraepithelial neoplasia and HPV vaccination programmes to prevent cervical cancer, especially among users of combined contraceptives.


Does Interest in Sex Peak at Mid-Cycle in Ovulatory Menstrual Cycles of Healthy, Community-Dwelling Women? An 11-month Prospective Observational Study

Jerilynn C Prior

Vancouver Hospital and Health Sciences Centre

Abstract: Women's interest in sex is asserted to increase at the mid-cycle pre-ovulatory estradiol peak. We explored this belief in healthy, spontaneously normally menstruating/ovulating women. Women recorded "interest in sex" in a daily diary; validated Quantitative Basal Temperature analysis documented ovulation. Interest in sex showed no mid-cycle peak in 61 normal-weight, nonsmoking women, ages 33.7 ± 5.6 years, over a mean of 311 consecutive days. The cycle-plotted diary "self-worth" factor (including feelings of energy, interest in sex) also showed no mid-cycle peak. Thus, interest in sex is related more strongly to women's feelings/experiences than to hormones, challenging deterministic or sex-hormone-dependent cultural and sociobiological understandings.


Digital foot health technology and diabetic foot monitoring: A systematic review

Clifford DeRaffaele

Faculty of Health Sciences, University of Malta, Malta.

Abstract:
Background: In diabetic foot ulceration, a correlation between pressure and skin temperature is suspected. The aim of this systematic review is to provide a more rigorous analysis of existing literature related to the various technologies used to read and measure both in-shoe plantar pressures, and in-shoe skin temperatures simultaneously.

Methods: A systematic review of the literature related to the topic was searched in database sources such as Medline OVID, Cochrane Library, PubMed, CONAHL, PROSPERO, and Elsevier. Outcome measures of interest included validity, reliability and responsiveness of in-shoe temperature and/or pressure mapping device used, and characteristics and quantity of sensors used, anatomical landmarks and statistical analysis used to interpret the data. Quality of evidence and risk of bias was evaluated using the QUADAS-2.

Results: Nineteen studies were identified and included in this review. The majority of studies used a small sample size (mean n = 17) and recruited healthy participants. All studies have shown excellent validity but only a few tested for the reliability of the device. None of the studies tested for responsiveness of the device. Quality assessment results scored high risk in view of 'patient selection', 'use of reference standard' and 'applicability', and low risk in view of 'use if index test' and 'flow and timing'.

Conclusions: The data outlined in this review confirms that further improvement, reliability testing and clinical validation of the developed systems is required despite the results of excellent performance in detecting changes of in-shoe skin temperature and pressure.


A narrative review of platelet-rich plasma (PRP) in reproductive medicine

Sara Rahman

Virginia Center for Reproductive Medicine

Abstract:
Purpose: Platelet-rich plasma (PRP) has become a novel treatment in various aspects of medicine including orthopedics, cardiothoracic surgery, plastic surgery, dermatology, dentistry, and diabetic wound healing. PRP is now starting to become an area of interest in reproductive medicine more specifically focusing on infertility. Poor ovarian reserve, menopause, premature ovarian failure, and thin endometrium have been the main areas of research. The aim of this article is to review the existing literature on the effects of autologous PRP in reproductive medicine providing a summation of the current studies and assessing the need for additional research.

Methods: A literature search is performed using PubMed, MEDLINE, and CINAHL Plus to identify studies focusing on the use of PRP therapy in reproductive medicine. Articles were divided into 3 categories: PRP in thin lining, PRP in poor ovarian reserve, and PRP in recurrent implantation failure.

Results: In women with thin endometrium, the literature shows an increase in endometrial thickness and increase in chemical and clinical pregnancy rates following autologous PRP therapy. In women with poor ovarian reserve, autologous intraovarian PRP therapy increased anti-Mullerian hormone (AMH) levels and decreased follicle-stimulating hormone (FSH), with a trend toward increasing clinical and live birth rates. This trend was also noted in women with recurrent implantation failure.

Conclusions: Limited literature shows promise in increasing endometrial thickness, increasing AMH, and decreasing FSH levels, as well as increasing chemical and clinical pregnancy rates. The lack of standardization of PRP preparation along with the lack of large randomized controlled trials needs to be addressed in future studies. Until definitive large RCTs are available, PRP use should be considered experimental.

Goals, life events, and transitions: examining fertility apps for holistic health  tracking

Abstract:
Objective: Fertility is becoming increasingly supported by consumer health technologies, especially mobile apps that support self-tracking activities. However, it is not clear whether the apps support the variety of goals and life events of those who menstruate, especially during transitions between them.

Methods: Thirty-one of the most popular fertility apps were evaluated, analyzing data from three sources: the content of app store pages, app features, and user reviews.

Findings: Results suggest that fertility apps are designed to support specific life goals of people who menstruate, offering several data collection features and limited feedback options. However, users often desire holistic tracking that encompasses a variety of goals, life events, and the transitions among them.

DISCUSSION: These findings suggest fertility patients can benefit more from holistic self-tracking and provide insights for future design of consumer health technologies that better support holistic fertility tracking.

Conclusion: Fertility apps have the potential to support varied experiences of people who menstruate. But to achieve that, apps need to expand their support by offering ways for more users to perform holistic, personalized, and personally meaningful tracking, so they can derive long-term benefit from the data they collect.

Update on PCOS: Consequences, Challenges, and Guiding Treatment

Abstract: Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrine disorders in women and despite this, diagnostic challenges, delayed diagnosis, and less-than-optimal treatment regimens plague the condition. The International PCOS network, consisting of geographically diverse international experts in PCOS as well as consumers, engaged in a multi-year international evidence-based guideline development process that was jointly sponsored by the European Society for Human Reproduction and Embryology (ESHRE) and the American Society of Reproductive Medicine (ASRM). The guideline was published in 2018 and endorsed by more than 40 international societies involved in PCOS. Translation of this evidence-based guideline to medical practice and consumer groups remains a priority. However, there remain many challenges to both understanding the diagnosis and treatment of PCOS. Evidence suggests that both clinicians and consumers are not satisfied with the timeliness of diagnosis and treatment options. This review summarizes the important findings for diagnosis and treatment from the guidelines and expands on recent developments in the literature since its publication. Special attention to diagnosis at the ends of the reproductive spectrum are discussed and remaining areas of controversy are noted. Additionally, the review highlights some of the remaining challenges in the understanding and management of PCOS to help guide clinicians and investigators in this perplexing condition.

Combined Oral Contraceptive Use Increases the Risk of Venous Thromboembolism After Knee Arthroscopy and Anterior Cruciate Ligament Reconstruction: An Analysis of 64,165 Patients in the Truven Database

Abstract:
PURPOSE: To use the Truven MarketScan database to (1) report the incidence of venous thromboembolism (VTE), including deep vein thromboses (DVTs) and pulmonary embolism (PE), in patients undergoing simple knee arthroscopy and anterior cruciate ligament (ACL) reconstruction, and (2) evaluate combined oral contraceptive (COCP) use as a potential risk factor for VTE in patients undergoing knee arthroscopy.

METHODS: All female patients between the ages of 16 and 40 years undergoing knee arthroscopy and ACL reconstruction between 2010 and 2015 were identified in the MarketScan database. Patients were stratified by whether they had a documented pharmaceutical claim for COCP therapy, and the primary outcome was the risk of DVT and or PE within 90 postoperative days.

RESULTS: In total, 64,165 patients were identified for inclusion. While the overall incidence of VTE was low, patients taking COCPs had an increased risk of a DVT or PE compared with those not on COCPs (odds ratio [OR] 2.1, P < .001). When patients were analyzed by procedural subgroup (ACL reconstruction and simple knee arthroscopy), similar results held true. Furthermore, smoking and obesity had a synergistic effect when combined with COCPs use on the risk of VTE. Specifically, 3.1% of patients with obesity on COCPs (OR 3.1, P < .001) and 4.0% of smokers on COCPs (OR 4.3, P < .001) developed a postoperative VTE.

CONCLUSIONS: This study demonstrates that COCP use is associated with an increased risk for a symptomatic DVT or PE (1.70% and 0.27%, respectively) after knee arthroscopy and an increased risk for DVT, but not PE (1.80% and 0.23%, respectively), after ACL reconstruction. In addition, patients with multiple risk factors present such as tobacco use, obesity, and COCP use had odds ratios greater than the sum of the individual risk factors alone.

LEVEL OF EVIDENCE: level III prognostic cohort study.

Abstract: A growing body of evidence supports the modulation of pain by light exposure. As such, phototherapy is being increasingly utilized for the management of a variety of pain conditions. The modes of delivery, and hence applications of phototherapy, vary by wavelength, intensity, and route of exposure. As such, differing mechanisms of action exist depending upon those parameters. Cutaneous application of red light (660 nm) has been shown to reduce pain in neuropathies and complex regional pain syndrome-I, whereas visual application of the same wavelength of red light has been reported to exacerbate migraine headache in patients and lead to the development of functional pain in animal models. Interestingly visual exposure to green light can result in reduction in pain in variety of pain conditions such as migraine and fibromyalgia. Cutaneous application typically requires exposure on the order of minutes, whereas visual application requires exposure on the order of hours. Both routes of exposure elicit changes centrally in the brainstem and spinal cord, and peripherally in the dorsal root ganglia and nociceptors. The mechanisms of photobiomodulation of pain presented in this review provide a foundation in furtherance of exploration of the utility of phototherapy as a tool in the management of pain. PERSPECTIVE: This review synopsizes the pathways and mechanisms through which light modulates pain and the therapeutic utility of different colors and exposure modalities of light on pain. Recent advances in photobiomodulation provide a foundation for understanding this novel treatment for pain on which future translational and clinical studies can build upon.


The Prevalence of Polycystic Ovary Syndrome: A Brief Systematic Review

Amita Dang

Center for Medical Biotechnology, MD University, Rohtak, Haryana, India.

Abstract:
Background: Polycystic ovary syndrome (PCOS), the major endocrinopathy among reproductive-aged women, is not yet perceived as an important health problem in the world. It affects 4%-20% of women of reproductive age worldwide. The prevalence, diagnosis, etiology, management, clinical practices, psychological issues, and prevention are some of the most confusing aspects associated with PCOS.

Aim: The exact prevalence figures regarding PCOS are limited and unclear. The aim of this review is to summarize comprehensively the current knowledge on the prevalence of PCOS.

Materials and Methods: Literature search was performed through PubMed, ScienceDirect, Cochrane Library, and Google Scholar (up to December 2019). All relevant articles published in English language were identified following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results: Our analysis yielded 27 surveys with a pooled mean prevalence of 21.27% using different diagnostic criteria. The proportion of women with PCOS also increased in the last decade.

Conclusion: The current review summarizes and interprets the results of all published prevalence studies and highlights the burden of the syndrome, thereby supporting early identification and prevention of PCOS in order to reverse the persistent upward trend of prevalence.


The Menstrual Disturbances in Endocrine Disorders: A Narrative Review

Abstract:
Context: Menstrual cycle is considered the fifth vital sign among women. This study aimed to summarize the menstrual disturbances in different endocrine disorders.
Evidence Acquisition: In this narrative review, relevant studies (up to December 2019) were searched based on the MeSH keywords diabetes, polycystic ovary syndrome, Cushing's syndrome, thyroid dysfunction, hyperprolactinemia, menstrual cycle, uterine bleeding, and menstruation. Databases used for searching articles included Google Scholar, Scopus, PubMed, and Web of science for observational, experimental, and review studies.

Results: Endocrine disorders trigger the onset of menstrual disturbance across the reproductive lifespan of women. Endocrine glands (pituitary, thyroid, pancreas, adrenal, and ovaries) have a functional role in endocrine regulation of the menstrual cycle. According to available evidence, oligomenorrhea (cycles longer than 35 days) is the most common menstrual disturbance among endocrine disorders (thyrotoxicosis, hypothyroidism, polycystic ovary syndrome, Cushing's syndrome, and diabetes). Complex endocrine pathways play an essential role in a women's menstrual calendar.

Conclusions: The menstrual cycle length and amount of bleeding can be indicative of endocrine disorders. Further studies are needed to identify the unknowns about the association between endocrine disorders and the menstrual cycle.

Short-term Western-style diet negatively impacts reproductive outcomes in primates

Abstract: A maternal Western-style diet (WSD) is associated with poor reproductive outcomes, but whether this is from the diet itself or underlying metabolic dysfunction is unknown. Here, we performed a longitudinal study using regularly cycling female rhesus macaques (n = 10) that underwent 2 consecutive in vitro fertilization (IVF) cycles, one while consuming a low-fat diet and another 6-8 months after consuming a high-fat WSD. Metabolic data were collected from the females prior to each IVF cycle. Follicular fluid (FF) and oocytes were assessed for cytokine/steroid levels and IVF potential, respectively. Although transition to a WSD led to weight gain and increased body fat, no difference in insulin levels was observed. A significant decrease in IL-1RA concentration and the ratio of cortisol/cortisone was detected in FF after WSD intake. Despite an increased probability of isolating mature oocytes, a 44% reduction in blastocyst number was observed with WSD consumption, and time-lapse imaging revealed delayed mitotic timing and multipolar divisions. RNA sequencing of blastocysts demonstrated dysregulation of genes involved in RNA binding, protein channel activity, mitochondrial function and pluripotency versus cell differentiation after WSD consumption. Thus, short-term WSD consumption promotes a proinflammatory intrafollicular microenvironment that is associated with impaired preimplantation development in the absence of large-scale metabolic changes.


The Impact of Menstrual Cycle Phase on Athletes' Performance: A Narrative Review

Abstract: The effect of the menstrual cycle on physical performance is being increasingly recognised as a key consideration for women's sport and a critical field for further research. This narrative review explores the findings of studies investigating the effects of menstrual cycle phase on perceived and objectively measured performance in an athletic population. Studies examining perceived performance consistently report that female athletes identify their performance to be relatively worse during the early follicular and late luteal phases. Studies examining objective performance (using anaerobic, aerobic or strength-related tests) do not report clear, consistent effects of the impact of menstrual cycle phase on physical performance. Overall sport performance can be influenced by both perceived and physical factors. Hence, to optimise performance and management of eumenorrheic female athletes, there is a need for further research to quantify the impact of menstrual cycle phase on perceived and physical performance outcomes and to identify factors affecting variability in objective performance outcomes between studies.

"Biophysical effects, safety and efficacy of raspberry leaf use in pregnancy: a systematic integrative review"

Deborah Davis

University of Canberra, 11 Kirinari St, Bruce ACT, 2617, Australia. Deborah.davis@canberra.edu.au.

Abstract:
Background: Childbearing women have been using various herbs to assist with pregnancy, labour and birth for centuries. One of the most common is raspberry leaf. The evidence base for the use of raspberry leaf is however under-developed. It is incumbent on midwives and other maternity care providers to provide women with evidence-based information so they can make informed choices. The aim of this study was to review the research literature to identify the evidence base on the biophysical effects, safety and efficacy of raspberry leaf in pregnancy.

Methods: A systematic, integrative review was undertaken. Six databases were searched to identify empirical research papers published in peer reviewed journals including in vitro, in vivo, human and animal studies. The search included the databases CINAHL, MEDLINE, Cochrane Library, Scopus and Web of Science Core Collection and AMED. Identified studies were appraised independently by two reviewers using the MMAT appraisal instrument. An integrative approach was taken to analysis.

Results: Thirteen studies were included. Five were laboratory studies using animal and human tissue, two were experiments using animals, and six were human studies. Included studies were published between 1941 and 2016. Raspberry leaf has been shown to have biophysical effects on animal and human smooth muscle including the uterus. Toxity was demonstrated when high doses were administered intravenously or intaperitoneally in animal studies. Human studies have not shown any harm or benefit though one study demonstrated a clinically meaningful (though non-statistically significant) reduction in length of second stage and augmentation of labour in women taking raspberry leaf.

Conclusions: Many women use raspberry leaf in pregnancy to facilitate labour and birth. The evidence base supporting the use of raspeberry leaf in pregnancy is weak and further research is needed to address the question of raspberry leaf’s effectiveness.

Abstract:
Purpose: Digital fertility awareness-based contraception offers an alternative choice for women who do not wish to use hormonal or invasive methods. The aim of this study was to investigate the key demographics of current users of the Natural Cycles app and assess the contraceptive outcomes of women preventing pregnancy in a UK cohort of women.

Materials and Methods: This was a real world observational prospective observational study. The typical-use effectiveness of the method was calculated using both 13-cycle cumulative probability of pregnancy (life table analysis) and Pearl Index for the entire study cohort. Perfect-use PI was calculated using data from cycles where sexual intercourse during the fertile window was marked as protected and no unprotected sex was recorded on fertile days.

Results: 12,247 women were included in the study and contributed an average of 9.9 months of data for a total of 10,066 woman years of exposure. The mean age of the cohort was 30, mean BMI 23.4, the majority were in a stable relationship (83.2%) and had a university degree or higher (83%). The one year typical use, PI was 6.1 (95% CI: 5.6, 6.6) and with perfect-use was 2.0 (95% CI: 1.3, 2.8). 13 cycle pregnancy probability was 7.1%.

Conclusions: This is the first study which describes the use of a digital contraceptive by women in the UK. It describes the demographics of users and how they correlate with the apps effectiveness at preventing pregnancy.

Natural Family Planning and Marital Chastity: The Effects of Periodic Abstinence  on Marital Relationships

Abstract:
Marital chastity is the practice of periodic abstinence with use of natural family planning (NFP). The purpose of this study was to determine the influence of the most common methods of contraception (female sterilization, oral contraceptive pills, and condoms) and NFP on divorce/separation and cohabitation rates among reproductive age women. The study involved an extensive review of the literature on the effects of practice of NFP on marital dynamics and a statistical analysis of 2,550 ever-married women in the (2015-2017) National Survey of Family Growth data set. Importance of religion and frequency of church attendance were included in the analysis. With ever-use of NFP, 14 percent were divorced or separated, and 27 percent to 39 percent were divorced or separated with ever-use of oral contraceptive pills. Stepwise logistic regression indicated that ever-use of contraception was associated with increased odds of divorce or separation (odds ratio [OR] = 2.05; confidence interval [CI]: 1.96-2.49) and cohabitation (2.95, CI: 2.20-3.95). Ever-use of NFP yielded 58 percent lower odds for divorce or separation. Frequent church attendance was associated with lower odds of divorce or separation and cohabitation. Although there are lower odds of divorce among NFP users, the reason might be due to their religiosity.
Summary: This study showed that ever-use of natural family planning (NFP) among ever-married women was associated with 58 percent lower odds of divorce than among women who never-used NFP. Ever-use of contraceptive methods was associated with two times the odds of divorce and four times for cohabitation compared to those women who never-used those methods. Use of periodic abstinence with NFP is the practice of marital chastity and is thought to strengthen the marital relationship.


Iodine and fertility: do we know enough?

Abstract: Iodine is a vital micronutrient and its importance in thyroid function is well established. However, abnormalities in iodine intake may also have other effects. In particular, iodine is taken up avidly by the ovary and endometrium. Iodine deficiency is associated with reduced fertility. The use of high iodine concentration contrast media has recently been shown to improve conception rates in couples with unexplained infertility (UI). We hypothesize that this improvement could be related to the iodine excess and mechanisms independent of its action on thyroid. In this article, the metabolism of iodine and its potential role in fertility will be discussed, including the impact of both iodine deficiency and excess states and the importance of iodine in normal fetal development. This will include insights from animal studies on the effect of iodine in the uterine and ovarian structural environment, hormonal milieu and immunological factors affecting implantation. We speculate that iodine may well have a role as a potential therapy for UI.


A Clinical Approach to Catamenial Epilepsy: A Review

Abstract:
Importance: Catamenial epilepsy (CE) is exacerbated by hormonal fluctuations during the menstrual cycle. Approximately 1.7 million women have epilepsy in the United States. CE affects more than 40% of women with epilepsy. There is a paucity of literature addressing this condition from a clinical standpoint, and the literature that does exist is limited to the neurological community. This article reviews the diagnosis and management of CE for the non-neurologist. Women with CE have early touch points in their care with numerous health care providers before ever consulting with a specialist, including OB/GYNs, pediatricians, emergency department physicians, and family medicine providers. In addition, women affected by CE have seizures that are more recalcitrant to traditional epilepsy treatment regimens. To optimize management in patients affected by CE, menstrual physiology must be understood, individualized hormonal contraception treatment considered, and adjustments and interactions with antiepileptic drugs addressed.
Observations: CE is a unique subset of seizure disorders affected by menstrual fluctuations of progesterone and estrogen. The diagnosis of CE has been refined and clarified. There is an ever-increasing understanding of the importance and variety of options of hormonal contraception available to help manage CE. Furthermore, antiepileptic drugs and contraception can interact, so attention must be directed to optimizing both regimens to prevent uncontrolled seizures and pregnancy. CONCLUSION AND RELEVANCE: CE can be diagnosed with charting of menstrual cycles and seizure activity. Hormonal treatments that induce amenorrhea have been shown to reduce CE. Optimizing antiepileptic drug dosing and contraceptive methods also can minimize unplanned pregnancies in women affected by CE.


Photobiomodulation: The Clinical Applications of Low-Level Light Therapy

Graeme Ewan Glass

Department of Surgery, Sidra Medicine, Doha, Qatar.

Abstract:
Background: Low-level light therapy (LLLT) is a recent addition to the pantheon of light-based therapeutic interventions. The absorption of red/near-infrared light energy, a process termed "photobiomodulation," enhances mitochondrial ATP production, cell signaling, and growth factor synthesis, and attenuates oxidative stress. Photobiomodulation is now highly commercialized with devices marketed directly to the consumer. In the gray area between the commercial and therapeutic sectors, harnessing the clinical potential in reproducible and scientifically measurable ways remains challenging.

Objectives: The aim of this article was to summarize the clinical evidence for photobiomodulation and discuss the regulatory framework for this therapy.

Methods: A review of the clinical literature pertaining to the use of LLLT for skin rejuvenation (facial rhytids and dyschromias), acne vulgaris, wound healing, body contouring, and androgenic alopecia was performed.

Results: A reasonable body of clinical trial evidence exists to support the role of low-energy red/near-infrared light as a safe and effective method of skin rejuvenation, treatment of acne vulgaris and alopecia, and, especially, body contouring. Methodologic flaws, small patient cohorts, and industry funding mean there is ample scope to improve the quality of evidence. It remains unclear if light-emitting diode sources induce physiologic effects of compararable nature and magnitude to those of the laser-based systems used in most of the higher-quality studies.

Conclusions: LLLT is here to stay. However, its ubiquity and commercial success have outpaced empirical approaches on which solid clinical evidence is established. Thus, the challenge is to prove its therapeutic utility in retrospect. Well-designed, adequately powered, independent clinical trials will help us answer some of the unresolved questions and enable the potential of this therapy to be realized.


Practical Clinical and Diagnostic Pathway for the Investigation of the Infertile Couple

Abstract: CAPSULE: This expert opinion summarizes current knowledge on risk factors for infertility and identifies a practical clinical and diagnostic approach for the male and female partners of an infertile couple aimed to improve the investigation and management of fertility problems. BACKGROUND: Infertility represents an important and growing health problem affecting up to 16% of couples worldwide. In most cases, male, female, or combined factor can be identified, and different causes or risk factors have been related to this condition. However, there are no standardized guidelines on the clinical-diagnostic approach of infertile couples and the recommendations concerning infertility are sometimes lacking, incomplete, or problematic to apply. OBJECTIVE: The aim of this work is to provide an appropriate clinical and diagnostic pathway for infertile couples designed by a multidisciplinary-team of experts. The rationale is based on the history and physical examination and then oriented on the basis of initial investigations. This approach could be applied in order to reduce variation in practice and to improve the investigation and management of fertility problems. METHODS: Prominent Italian experts of the main specialties committed in the ART procedures, including gynecologists, andrologists, embryologists, biologists, geneticists, oncologists, and microbiologists, called "InfertilItaly group", used available evidence to develop this expert position. OUTCOMES: Starting from the individuation of the principal risk factors that may influence the fertility of females and males and both genders, the work group identified most appropriate procedures using a gradual approach to both partners aimed to obtain a precise diagnosis and the most effective therapeutic option, reducing invasive and occasionally redundant procedures. CONCLUSIONS: This expert position provides current knowledge on risk factors and suggests a diagnostic workflow of infertile couples. By using this step-by-step approach, health care workers involved in ART, may individuate a practical clinical management of infertile couples shared by experts.


Effects of three contraceptive methods on depression and sexual function: An  ancillary study of the ECHO randomized trial

Mandisa Singata-Madliki

Deputy Director, Effective Care Research Unit (ECRU), Eastern Cape Department of Health, East London Hospital Complex, Universities of the Witwatersrand and Fort Hare, East London, South Africa

Abstract:
Objective: To compare the effects of depot medroxyprogesterone acetate (DMPA-IM), levonorgestrel (LNG) implant, and copper intrauterine device (IUD) on mood and sexual function.

Methods: At the Effective Care Research Unit in South Africa, women already randomized in the ECHO Trial to the three methods were asked to participate in this study. Participants were interviewed at 3 and 12 months after enrollment using the Beck Depression Inventory and Arizona Sexual Experiences Scale, and at 12 months using the WHO-5 Wellbeing Index and the Patient Global Impression scale.

Results: A total of 605 women participated. There was little difference in depression at 3 months across the three study groups. Contrary to our hypothesis, at 12 months, depression was lowest among DMPA-IM users (16/167, 9.6%) and highest among IUD users (28/158, 17.7%) (p = 0.032). There was little difference in sexual function at any time-point. More women in the DMPA-IM group felt "very much better" on the PGI scale than in the IUD and LNG implant groups (p = 0.003).

Conclusion: Depression may be less likely with DMPA-IM than with the other methods 1 year after initiation. Major differences in sexual functioning are unlikely. Unhappiness related to not using DMPA-IM, the most popular method in our setting, may have skewed results.

Abstract:
Prevention of early menopausal bone loss may reduce the future burden of osteoporosis. In this modelling exercise, an osteoporosis prevention strategy involving 5-year infusions of zoledronic acid, beginning early in menopause, reduced long-term fracture risk and the proportion of aging women with femoral neck densitometric osteoporosis. This strategy warrants further evaluation.
Introduction: Preventing early menopausal bone loss may substantially reduce the future burden of osteoporosis. We modelled the effects of infrequent zoledronic acid infusions on long-term fracture risk.

Methods: Data from the Canadian Multicentre Osteoporosis Study (CaMos) were used to determine the expected natural history of femoral neck areal bone mineral density (BMD) and fracture risk (using FRAX®) from ages 50-80 for women with no antiresorptive drug exposures. We modelled the effects of three infusions of zoledronic acid (at ages 50, 55, 60) on long-term fracture risk, assuming this intervention would preserve BMD until age 65 years, followed by losses mirroring early menopausal BMD loss.

Results: At age 65, untreated women and zoledronic acid recipients had expected mean (SD) femoral neck T-scores of - 1.5(1.0) and - 0.8(1.0), 10-year major osteoporotic fracture (MOF) risks of 9.8%(5.0) and 8.0%(3.7) and hip fracture risks of 1.7%(2.4) and 0.8%(1.2), respectively. At age 80, untreated women and zoledronic acid recipients had expected femoral neck T-scores of - 1.9(0.9) and - 1.4(0.9), MOF risks of 17.9%(8.2) and 14.9%(6.4) and hip fracture risks of 6.3%(6.2) and 4.4%(4.5), respectively. The expected proportion of women with femoral neck T-score ≤ - 2.5 was 14.9% for untreated women and 3.8% for zoledronic acid recipients at age 65, increasing to 28.1% and 12.0%, respectively, at age 80. Numbers-needed-to-treat to prevent one case of densitometric osteoporosis were 9 at age 65 and 5 at age 80.

Conclusion: Infrequent infusions of zoledronic acid, initiated early in menopause, are expected to reduce long-term fracture risk and result in a substantial reduction in the proportion of women with densitometric osteoporosis after age 65.


Post-caesarean Niche (Isthmocele) in Uterine Scar: An Update

Abstract: Uterine niche is one of the emerging complications of caesarean section. With rising caesarean rates, the caesarean-related iatrogenic complications are also on the rise. These include placenta accreta, scar ectopic pregnancy and uterine niche which is a newer entity being described in the recent literature. Uterine niche, also described as uterine isthmocele, caesarean scar defect and diverticulum, is an iatrogenic defect in the myometrium at the site of previous caesarean scar due to defective tissue healing. Patients may have varied symptoms including abnormal uterine bleeding, post-menstrual spotting and infertility, though many women may be asymptomatic and diagnosed incidentally. Diagnosis is made radiologically by transvaginal sonography, saline instillation sonohysterography or magnetic resonance imaging. Occurrence of niche may be prevented by using correct surgical technique during caesarean. Patients may be managed medically; however, subfertility and persistent symptoms may require surgical correction either by hysteroscopic resection or transabdominal or transvaginal repair. This mini-review comprehensively covers the potential risk factors, clinical presentation, diagnosis and management of this increasingly encountered condition due to rising caesarean rates.

Polycystic ovary syndrome and postpartum depression symptoms: a population-based  cohort study

Abstract:
Background: Women with polycystic ovary syndrome are more likely to experience several pregnancy complications including hypertensive disorders, gestational diabetes mellitus, and preterm births than women without polycystic ovary syndrome. However, at present, there is limited research on whether polycystic ovary syndrome is associated with both anxiety and depression during pregnancy and whether this augments a woman's risk of postpartum depression, particularly among high-risk populations who have limited access to care.

Objective: Our primary objective was to assess the association between prepregnancy polycystic ovary syndrome and postpartum depression, considering important baseline confounding factors. Our secondary objective was to evaluate the mediating role of prenatal depression and anxiety on the association between polycystic ovary syndrome and postpartum depression.

Study Design: This study involved a population-based sample of 3906 postpartum (2-6 months) women who completed the Utah Pregnancy Risk Assessment Monitoring System Phase 8 questionnaire (2016-2018). Weighted adjusted prevalence ratios were used to assess the association between polycystic ovary syndrome and postpartum depression, considering potential confounding factors and assessing mediating effects of depression and anxiety experienced during pregnancy.

Results: Following the exclusion criteria, 8.2% of women reported clinical polycystic ovary syndrome and 19.1%, 6.2%, and 4.4% reported irregular periods and acne, irregular periods and hirsutism, and all 3 symptoms, respectively. Moreover, 17.7% and 23.5% reported experiencing prenatal depression and anxiety and 9.5% and 10.2% reported experiencing postpartum depressed mood and anhedonia, respectively. Clinical polycystic ovary syndrome was associated with a 1.76 higher adjusted prevalence ratio (95% confidence interval, 1.03-3.00) for postpartum depressed mood or anhedonia after taking into consideration age, prepregnancy body mass index, race/ethnicity, education, and marital status. A similar higher prevalence was seen for irregular periods and acne (adjusted prevalence ratio, 1.65; 95% confidence interval, 1.13-2.41), irregular periods and hirsutism (adjusted prevalence ratio, 1.40; 95% confidence interval, 0.82-2.40), and all 3 symptoms (adjusted prevalence ratio, 1.75; 95% confidence interval, 0.96-3.19) and postpartum depressed mood or anhedonia. Prenatal depression and anxiety mediated 20% and 32% of the effect of clinical polycystic ovary syndrome on postpartum depressed mood and anhedonia, respectively.

Conclusion: Clinical polycystic ovary syndrome is associated with postpartum depressed mood and symptoms among this population-based sample inclusive of high-risk mothers. Prenatal depression and anxiety mediate this association, emphasizing the importance of prenatal psychological screening among women with polycystic ovary syndrome. An additional important clinical and public health implication of this study lies in the finding that nearly 20% of women in this population-based sample who reported at least 2 polycystic ovary syndrome symptoms (including at-risk women who may not have access to care) had not received a clinical diagnosis for polycystic ovary syndrome.

Inflammatory Mediators and Pain in Endometriosis: A Systematic Review

Abstract:
BACKGROUND: pain is one of the main symptoms of endometriosis and it has a deleterious effect on a patients' personal and social life. To date, the clinical management of pain includes prolonged medication use and, in some cases, surgery, both of which are disruptive events for patients. Hence, there is an urgency for the development of a sufficient non-invasive medical treatment. Inflammation is one of the causative factors of pain in endometriosis. It is well established that inflammatory mediators promote angiogenesis and interact with the sensory neurons inducing the pain signal; the threshold of pain varies and it depends on the state and location of the disease. The inhibition of inflammatory mediators' synthesis might offer a novel and effective treatment of the pain that is caused by inflammation in endometriosis.

OBJECTIVES: patients with endometriosis experience chronic pelvic pain, which is moderate to severe in terms of intensity. The objective of this systematic review is to highlight the inflammatory mediators that contribute to the induction of pain in endometriosis and present their biological mechanism of action. In addition, the authors aim to identify new targets for the development of novel treatments for chronic pelvic pain in patients with endometriosis.

DATA SOURCES: three databases (PubMed, Scopus, and Europe PMC) were searched in order to retrieve articles with the keywords 'inflammation, pain, and endometriosis' between the review period of 1 January 2016 to 31 December 2020. This review has been registered with PROSPERO (registry number: CRD42020171018). Eligibility Criteria: only original articles that presented the regulation of inflammatory mediators and related biological molecules in endometriosis and their contribution in the stimulation of pain signal were included.

DATA EXTRACTION: two authors independently extracted data from articles, using predefined criteria.

RESULTS: the database search yielded 1871 articles, which were narrowed down to 56 relevant articles of interest according to the eligibility criteria.

CONCLUSIONS: inflammatory factors that promote angiogenesis and neuroangiogenesis are promising targets for the treatment of inflammatory pain in endometriosis. Specifically, CXC chemokine family, chemokine fractalkine, and PGE2 have an active role in the induction of pain. Additionally, IL-1β appears to be the primary interleukin (IL), which stimulates the majority of the inflammatory factors that contribute to neuroangiogenesis along with IL-6. Finally, the role of Ninj1 and BDNF proteins needs further investigation.


The Impact of the Menstrual Cycle and Underlying Hormones in Anxiety and PTSD: What Do We Know and Where Do We Go From Here?

Abstract:
PURPOSE OF REVIEW: This paper reviews the recent literature on menstrual cycle phase effects on outcomes relevant to anxiety and PTSD, discusses potential neurobiological mechanisms underlying these effects, and highlights methodological limitations impeding scientific advancement.

RECENT FINDINGS: The menstrual cycle and its underlying hormones impact symptom expression among women with anxiety and PTSD, as well as psychophysiological and biological processes relevant to anxiety and PTSD. The most consistent findings are retrospective self-report of premenstrual exacerbation of anxiety symptoms and the protective effect of estradiol on recall of extinction learning among healthy women. Lack of rigorous methodology for assessing menstrual cycle phase and inconsistent menstrual cycle phase definitions likely contribute to other conflicting results. Further investigations that address these limitations and integrate complex interactions between menstrual cycle phase-related hormones, genetics, and psychological vulnerabilities are needed to inform personalized prevention and intervention efforts for women.


The Value of Anti-Müllerian Hormone in the Prediction of Spontaneous Pregnancy: A Systematic Review and Meta-Analysis

Ying-Ming Zheng

Women's Hospital, School of Medicine, Zhejiang University

Abstract: To determine whether serum anti-Müllerian hormone (AMH) level is a predictor of clinical pregnancy in women trying to achieve a natural conception. Eleven studies (4,388 women) were ultimately included in this meta-analysis. The AUC and Cochran Q indices were 0.5932 and 0.5702, respectively. Serum AMH levels have poor predictive value for natural pregnancy. Our findings suggest that low serum AMH levels are not associated with reduced fertility.

Significance of dynamically monitoring serum estrogen and β-human chorionic gonadotropin in early pregnancy assessment

Yuhua Li

Third Affiliated Hospital of Guangzhou Medical University

Abstract:
BACKGROUND: Spontaneous abortion occurs in 15% ~ 25% of clinical pregnancy. β-human chorionic gonadotropin (β-HCG) and progesterone (P) have been widely used in early pregnancy assessment, but their clinical significances are still controversial. Estradiol (E2) has not been used as widely as β-HCG and P, and its value in predicting pregnancy outcome is unclear.

METHODS: In this retrospective study, two hundred early pregnancy women were divided into two groups according to their early pregnancy outcomes: the ongoing pregnancy group and inevitable abortion group. Serum E2 and β-HCG levels and their growth rates were compared weekly.

RESULTS: Estradiol and β-HCG of the ongoing pregnancy group were significantly higher than that of the inevitable abortion group from the 5th to 10th week of pregnancy. Taking 489.5 pg/mL in the 5th and 6th week, 590.5 pg/mL in the 7th week, and 614.5 pg/mL in the 8th week as cutoff levels of E2, the sensitivity and specificity for E2 to predict bad pregnancy outcome were 91.7% and 41.5%, 82.9% and 71.1%, 84.8% and 84.7%, 75.0% and 95.7%, respectively (P < .05). Both E2 and β-HCG increased much more rapidly in the ongoing pregnancy group. 80% of the normal pregnancy women showed continuously increasing E2 level. Meanwhile, the inevitable abortion group presented E2 variation types as slow increase or fluctuation, continuous decline, and sudden drop, which account for 54.0%, 34.0%, and 12.0%, respectively.

CONCLUSION: Low values and low growth rates of E2 and β-HCG probably indicate bad pregnancy outcomes.


Can periodontal disease affect conception? A literature review

Abstract:
Today periodontal health is considered as an integral part of systemic health itself and no longer as a single factor. The literature recognizes that the presence of periodontal disease can represent a risk factor for numerous systemic conditions such as heart disease and diabetes. In recent years, we have witnessed a progressive interest regarding the influence exerted by this condition on reproduction, as well as the possible repercussions on conception possibilities. Upon analyzing a limited number of studies available for the correlation between periodontal disease and female infertility, it could be inferred that this condition can be equated to the presence of a real outbreak of infection and therefore exert its influence, not only through bacterial translocation in the bloodstream, causing the systemic dissemination of pathogens, but also through the production of cytokines and immunoglobulins by inflammatory mediators. This situation limits bacterial growth, but it could cause damage to the fetus, to the reproductive system, and could hinder conception attempts. Although further research is needed to better clarify the mechanism underlying the possible correlation between periodontal disease and female infertility, the present article aims to review all the available literature on this topic.

LAY SUMMARY: In recent years, interest regarding the influence of gum disease on conception has increased. Since serious gum disease (periodontitis) can be compared to an outbreak of infection, studies suggest that the bacteria that mediate inflammation do not remain confined only to the gum tissue, but can enter the bloodstream and spread, thus spreading the infection and having a whole-body effect. This situation could cause damage to the developing baby, to the reproductive system and could hinder conception attempts. Constant maintenance of oral health is definitely necessary. It is important for the professionals involved (gynecologists, obstetricians, dentists, etc.) to communicate and collaborate on these issues. Dentists could advise on the correct hygienic maintenance not only to pregnant women, but also to those who are planning a pregnancy in order to avoid the occurrence of unfavorable conditions.


Interpregnancy intervals and adverse birth outcomes in high-income countries: An international cohort study

Abstract:
BACKGROUND: Most evidence for interpregnancy interval (IPI) and adverse birth outcomes come from studies that are prone to incomplete control for confounders that vary between women. Comparing pregnancies to the same women can address this issue.

METHODS: We conducted an international longitudinal cohort study of 5,521,211 births to 3,849,193 women from Australia (1980-2016), Finland (1987-2017), Norway (1980-2016) and the United States (California) (1991-2012). IPI was calculated based on the time difference between two dates-the date of birth of the first pregnancy and the date of conception of the next (index) pregnancy. We estimated associations between IPI and preterm birth (PTB), spontaneous PTB, and small-for-gestational age births (SGA) using logistic regression (between-women analyses). We also used conditional logistic regression comparing IPIs and birth outcomes in the same women (within-women analyses). Random effects meta-analysis was used to calculate pooled adjusted odds ratios (aOR).

RESULTS: Compared to an IPI of 18-23 months, there was insufficient evidence for an association between IPI <6 months and overall PTB (aOR 1.08, 95% CI 0.99-1.18) and SGA (aOR 0.99, 95% CI 0.81-1.19), but increased odds of spontaneous PTB (aOR 1.38, 95% CI 1.21-1.57) in the within-women analysis. We observed elevated odds of all birth outcomes associated with IPI ≥60 months. In comparison, between-women analyses showed elevated odds of adverse birth outcomes for <12 month and >24 month IPIs.

CONCLUSIONS: We found consistently elevated odds of adverse birth outcomes following long IPIs. IPI shorter than 6 months were associated with elevated risk of spontaneous PTB, but there was insufficient evidence for increased risk of other adverse birth outcomes. Current recommendations of waiting at least 24 months to conceive after a previous pregnancy, may be unnecessarily long in high-income countries.


Influence of Titanium Dioxide Nanoparticles on Human Health and the Environment

Abstract: Nanotechnology has enabled tremendous breakthroughs in the development of materials and, nowadays, is well established in various economic fields. Among the various nanomaterials, TiO2 nanoparticles (NPs) occupy a special position, as they are distinguished by their high availability, high photocatalytic activity, and favorable price, which make them useful in the production of paints, plastics, paper, cosmetics, food, furniture, etc. In textiles, TiO2 NPs are widely used in chemical finishing processes to impart various protective functional properties to the fibers for the production of high-tech textile products with high added value. Such applications contribute to the overall consumption of TiO2 NPs, which gives rise to reasonable considerations about the impact of TiO2 NPs on human health and the environment, and debates regarding whether the extent of the benefits gained from the use of TiO2 NPs justifies the potential risks. In this study, different TiO2 NPs exposure modes are discussed, and their toxicity mechanisms—evaluated in various in vitro and in vivo studies—are briefly described, considering the molecular interactions with human health and the environment. In addition, in the conclusion of this study, the toxicity and biocompatibility of TiO2 NPs are discussed, along with relevant risk management strategies.


Applications of Melatonin in Female Reproduction in the Context of Oxidative Stress

Abstract: Oxidative stress has been recognized as one of the causal mediators of female infertility by affecting the oocyte quality and early embryo development. Improving oxidative stress is essential for reproductive health. Melatonin, a self-secreted antioxidant, has a wide range of effects by improving mitochondrial function and reducing the damage of reactive oxygen species (ROS). This minireview illustrates the applications of melatonin in reproduction from four aspects: physiological ovarian aging, vitrification freezing, in vitro maturation (IVM), and oxidative stress homeostasis imbalance associated with polycystic ovary syndrome (PCOS), emphasising the role of melatonin in improving the quality of oocytes in assisted reproduction and other adverse conditions.

Changes in the level of fetoplacental complex hormones in pregnant women with miscarriage

Abstract: The purpose of the study was TO analyze the fetoplacental complex hormone levels and changes in their dynamics in pregnant women with miscarriage and the impact of these features on the subsequent course of pregnancy. Hormone levels were determined at different stages of gestation in 50 healthy women with a physiological course of pregnancy (control group) and 50 pregnant women with a history of miscarriage (main group). The women of the main group had a significantly slower rate of increase in hormones and a lag in quantitative indicators than the control group. The estradiol level indicators were 4.1 times (76.0%) and 2.89 times (65.5%) lower in women with miscarriage in the embryonic and late fetal period, respectively, compared to healthy women. Indicators of the level of placental lactogen and chorionic gonadotropin in the embryonic period in women with miscarriage were lower by 39.1% and 50.9%, respectively, compared to healthy women. In the late fetal period, the level of these hormones was lower by 72.9% and 35.4%, respectively. In the embryonic and late fetal periods, progesterone levels were lower by 67.4% and 68.4%, respectively, compared to the control group. The data obtained are evidence of a pronounced hormonal abnormality of the placenta, and hence a marker of fetoplacental dysfunction, which on the background of miscarriage develops at the early stages and continues to progress with the course of pregnancy.


Complementary and Alternative Medicine for Dysmenorrhea Caused by Endometriosis: A Review of Utilization and Mechanism

Abstract: Endometriosis (EM) is a common and benign estrogen-dependent gynecological disorder among women of reproductive age, and secondary dysmenorrhea is one of the more severe symptoms. However, the mechanism behind the development of dysmenorrhea is poorly understood, and there is a lack of effective methods for diagnosing and treating EM dysmenorrhea. In this regard, complementary and alternative medicine (CAM) has recently come into widespread use due to its limited adverse reactions and high efficiency. This review updates the progress of CAM in the treatment of EM dysmenorrhea and seeks to identify the therapeutic efficacy as well as the mechanisms behind these effects based on the available clinical and experimental studies. According to the literature, CAM therapy for EM dysmenorrhea, including herbs (herbal prescriptions, extracts, and patents), acupuncture, and Chinese herbal medicine enema (CHM enema), is effective for relieving dysmenorrhea with fewer unpleasant side effects when compared to hormonal and surgical treatments. In addition, we discuss and analyze the existing gaps in the literature. We hope to provide some instructive suggestions for clinical treatment and experimental research in the future.

Low energy availability: history, definition and evidence of its endocrine, metabolic and physiological effects in prospective studies in females and males

Abstract: Energy availability (EA) is defined as the amount of dietary energy available to sustain physiological function after subtracting the energetic cost of exercise. Insufficient EA due to increased exercise, reduced energy intake, or a combination of both, is a potent disruptor of the endocrine milieu. As such, EA is conceived as a key etiological factor underlying a plethora of physiological dysregulations described in the female athlete triad, its male counterpart and the Relative Energy Deficiency in Sport models. Originally developed upon female-specific physiological responses, this concept has recently been extended to males, where experimental evidence is limited. The majority of data for all these models are from cross-sectional or observational studies where hypothesized chronic low energy availability (LEA) is linked to physiological maladaptation. However, the body of evidence determining causal effects of LEA on endocrine, and physiological function through prospective studies manipulating EA is comparatively small, with interventions typically lasting ≤ 5 days. Extending laboratory-based findings to the field requires recognition of the strengths and limitations of current knowledge. To aid this, this review will: (1) provide a brief historical overview of the origin of the concept in mammalian ecology through its evolution of algebraic calculations used in humans today, (2) Outline key differences from the 'energy balance' concept, (3) summarise and critically evaluate the effects of LEA on tissues/systems for which we now have evidence, namely: hormonal milieu, reproductive system endocrinology, bone metabolism and skeletal muscle; and finally (4) provide perspectives and suggestions for research upon identified knowledge gaps.


Naprotechnologia – szansa na potomstwo czy oszustwo?

Abstract: NaProTECHNOLOGY – a chance for offspring or fraud? In the media space in Poland, you can meet the concept of Naprotechnology as an alternative to the in vitro procedure. Often, many myths and untruths appear in the discussion regarding this method of treatment. Naprotechnology is a new look at the health of women and men created by prof. Thomas Hilgers. It takes into account natural fertility biomarkers thanks to observation with the Creighton Model based on the female mucus. At every stage of diagnosis and treatment, Naprotechnology respects human life from the moment of conception and the mutual dignity of the spouses. It also does not use assisted reproductive procedures for ethical reasons. Naprotechnology is part of the broader scientific discipline of restorative medicine in infertility. Thanks to the accurate diagnosis and observation of the cycle, it is possible to correctly diagnose the cause of infertility. A proper diagnosis is the starting point for the implementation of specialized pharmacological and surgical treatment for both women and men. Properly used Naprotechnology and restorative medicine are highly effective in treating marital infertility. W przestrzeni medialnej w Polsce można spotkać pojęcie Naprotechnologii jako alternatywy dla procedury in vitro. Często w dyskusji pojawia się wiele mitów i nieprawdy dotyczących takiego sposobu leczenia. Naprotechnologia, stworzona przez prof. Thomasa Hilgersa, jest nowym spojrzeniem na zdrowie kobiety i mężczyzny. Uwzględnia ona naturalne biomarkery płodności dzięki obserwacji za pomocą Modelu Creighton bazującego na kobiecym śluzie. Na każdym etapie diagnostyki i leczenia Naprotechnologia szanuje ludzkie życie od samego poczęcia oraz wzajemną godność małżonków. Nie stosuje ona też procedur wspomaganego rozrodu z powodów etycznych. Naprotechnologia jest częścią szerszej dyscypliny naukowej, jaką jest przyczynowe leczenie niepłodności. Dzięki dokładnej diagnostyce i obserwacji cyklu możliwe jest postawienie prawidłowej diagnozy dotyczącej przyczyny niepłodności. Właściwa diagnoza jest punktem wyjścia dla wdrożenia specjalistycznego leczenia farmakologicznego i chirurgicznego zarówno wobec kobiety, jak i mężczyzny. Prawidłowo stosowana Naprotechnologia i przyczynowe leczenie niepłodności cechują się wysoką skutecznością leczenia niepłodności małżeńskiej.

The Role of Oxytocin and the Effect of Stress During Childbirth: Neurobiological Basics and Implications for Mother and Child

Abstract: The neuropeptide oxytocin acts as a hormone and a neuromodulator, influencing a multitude of human social behaviors, including reproduction. During childbirth and the postpartum period, it plays a key role in regulating and controlling processes that ensure a safe birth and the health of mother and child. Especially the onset of labor, the progress of labor and initial breastfeeding are mediated by oxytocin. In the maternal brain it controls the initiation of the mother-infant bond and the mother's emotional responses towards her child. In this review we summarize the current state of knowledge about the role of oxytocin during the different aspects and mechanisms of human childbirth, combining research from human and animal studies. Physiological and psychological stress during childbirth and lactation can have negative effects on the progress of labor, breastfeeding and bonding. We discuss how maternity caregivers can support the positive effects of oxytocin and minimize the effects of stress. Furthermore, we highlight aspects of the basic neurobiological principles and connections where further research is needed to improve our understanding of the regulation and the effects of oxytocin to support maternal and infant health.


Diagnosis and treatment of infertility in men: AUA/ASRM guideline part I

Abstract:
PURPOSE: The summary presented herein represents Part I of the two-part series dedicated to the Diagnosis and Treatment of Infertility in Men: AUA/ASRM Guideline. Part I outlines the appropriate evaluation of the male in an infertile couple. Recommendations proceed from obtaining an appropriate history and physical exam (Appendix I), as well as diagnostic testing, where indicated.

MATERIALS/METHODS: The Emergency Care Research Institute Evidence-based Practice Center team searched PubMed®, Embase®, and Medline from January, 2000 through May, 2019. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. (Table 1) This summary is being simultaneously published in Fertility and Sterility and The Journal of Urology.

RESULTS: This Guideline provides updated, evidence-based recommendations regarding evaluation of male infertility as well as the association of male infertility with other important health conditions. The detection of male infertility increases the risk of subsequent development of health problems for men. In addition, specific medical conditions are associated with some causes for male infertility. Evaluation and treatment recommendations are summarized in the associated algorithm. (Figure 1) CONCLUSION: The presence of male infertility is crucial to the health of patients and its effects must be considered for the welfare of society. This document will undergo updating as the knowledge regarding current treatments and future treatment options continues to expand.


The Effects of Menstrual Cycle Phase on Elite Athlete Performance: A Critical and Systematic Review

Abstract: Background: In elite athletes, training individualization is widely recommended to optimize competitive performance. Previous studies have evidenced the impact of hormonal fluctuations on different performance parameters among female athletes. While consideration of menstrual cycle (MC) phases as a parameter in training individualization strategies is necessary, systematic evidence identifying such impacts in elite athletes should be evaluated. Objective: Systematically review publications that have investigated the link between MC phases and performance in elite female athletes. The overarching aim is to identify whether a consensus across studies exists enabling evidence-based recommendations for training individualization depending on menstrual cycle phases. Methods: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three major scientific publication databases were searched from inception until November 3, 2020. Studies included focused on the influence of physiological or psychological parameters throughout at least one phase of the menstrual cycle of elite athletes. Results: A total of 780 search results were yielded and 26 references from a past bibliography were added manually. About 662 papers were reviewed of which 218 studies were assessed for eligibility. Of these, only seven (1%) precisely investigated the influence of a performance or physical parameter during at least one menstrual cycle phase. These seven studies included a total of 314 elite female participants (20.58 ± 1.91 years). Three used interviews, questionnaires or prospective analyses of reports. Four conducted several performance tests or included physical measures although only two performed tests during training or before/during competition. Among the seven studies, five performed hormonal testing through sampling of blood, saliva, or urine. The remaining relied on athletes' menstruation diaries. The current evidence suggests a variable association between menstrual cycle and a few performance-related outcomes, such as endurance or power resistance, ligament stiffness, decision making skills, psychology, or competitiveness. Conclusion: Different sports performance-related parameters are affected during the menstrual cycle among elite athletes, but the parameters themselves and the magnitude and the direction of the effects are inconclusive. Additional longitudinal and prospective studies to systematically monitor on-field performance parameters are urgently required in order to enable recommendations and training individualization in female elite athletes.


Transvaginal Photobiomodulation for the Treatment of Chronic Pelvic Pain: A Pilot Study

Abstract: Background: Chronic pelvic pain (CPP) is a common and debilitating condition that affects millions of U.S. women. Most treatments are ineffective and innovative new therapies are desperately needed. Large, controlled studies show that photobiomodulation (PBM) can reduce pain in patients with other chronic pain conditions, such as low back pain, neck pain, and fibromyalgia. The objective of this pilot study was to determine if transvaginal PBM (TV-PBM) can reduce pain in women with CPP. Methods: We conducted a before and after, observational, pilot study. Patients completed the Short Form-McGill Pain Questionnaire (SF-MPQ) at baseline, 1 week, 3 months, and 6 months after nine treatments of TV-PBM. Clinicians completed the Clinical Global Impression Scale (CGI) assessing patient illness severity at the same time. Wilcoxon rank-sum t-tests and effect size using Cohen's d coefficient (low effect size if d < 0.2, medium if 0.2 < d > 8, and high if d > 0.8) was used to measure degree of pain improvement, which was also considered clinically significant if pain reduction was >30%. Results: Thirteen women completed 9 treatments, and 10 women were successfully followed to 6 months. At baseline, the mean SF-MPQ score was 19.7 (standard deviation [SD] ± 5.9). Compared with baseline, 60% improved; the mean SF-MPQ score decreased to 10.0 (SD ±7.5, p = 0.004, d = 1.6) at 1 week after treatment, to 9.7 (SD ±7.9, p = 0.005, d = 1.7) at 3 months, and 8.2 (SD ±8.1, p = 0.002, d = 1.9) at 6 months. Conclusion: Transvaginal PBM provided significant and sustained pain relief to women with CPP up to 6 months. Further controlled studies are needed to confirm these findings, however, in this initial pilot, TV-PBM shows promise.

Can Inhibin B Reflect Ovarian Reserve of Healthy Reproductive Age Women Effectively?

Abstract: The reference range and potential value of inhibin B are still unclear and controversial. This study aimed to define the variation trend of inhibin B in healthy women with age and explore its value in the reflection of ovarian reserve. A total of 2524 healthy reproductive age women from eight medical institutes nationwide were recruited. The variation tendency of inhibin B with age was primarily established in the first group of 948 women and validated in another 605. We evaluated the relationship between inhibin B and classic ovarian reserve and function markers. The potency of inhibin B in predicting AFC <5-7 was also estimated and compared with FSH. The nomogram showed that serum levels of inhibin B rapidly decreased after the age of 40. Inhibin B was positively correlated with AMH (R = 0.57, P < 0.001), AFC (R = 0.34, P < 0.001) and testosterone (R = 0.10, P = 0.002), and negatively correlated with FSH (R = -0.41, P < 0.001) and LH (R = -0.20, P < 0.001) and FSH/LH (R=-0.18, P < 0.001), while no correlation was found with PRL. Unexpectedly, Inhibin B (AUC = 0.74, P < 0.001 for the establishment population; AUC = 0.78, P < 0.001 for the validation population) had a slightly higher value than FSH (AUC = 0.71, P < 0.001 for the establishment population; AUC = 0.72, P < 0.001 for the validation population) in diagnosing AFC <5-7. For healthy reproductive age women, the decline of inhibin B can reflect decreased ovarian reserve effectively, having a good consistency with AMH and AFC. More importantly, inhibin B had an advantage in predicting AFC <5-7 compared with FSH, which suggested the potential of inhibin B in predicting ovarian response.


Changes in telomere length and senescence markers during human ovarian tissue cryopreservation

Abstract: Ovarian tissue cryopreservation is considered as a useful option to preserve fertility for cancer patients. This study purposed to evaluate the change of telomere length and senescence markers during human ovarian tissue cryopreservation. Ovarian tissues were obtained from women who underwent benign ovarian surgery in the gynecology research unit of a university hospital with prior consent and IRB approval. DNA was extracted from the ovarian tissues using a DNeasy tissue kit and telomere lengths in the DNA samples were determined by real time PCR before and after cryopreservation. All tissues were stained with hematoxylin-eosin and subjected to immunohistochemistry and TUNEL assays. Other senescence markers, including p53, p16, p21, and phospho-pRb proteins, were evaluated using western blot analysis. Ovarian tissues were collected from ten patients and prepared for slow freezing with the same size of diameter 4 mm and 1 mm thickness. Mean age of patients was 26.7 ± 6.2 years (range, 16-34 years), and ovarian tissues were cryopreserved and thawed 4 weeks after cryopreservation. The mean telomere length was significantly decreased after cryopreservation (9.57 ± 1.47 bp vs. 8.34 ± 1.83 bp, p = 0.001). Western blot analysis revealed that p53, p16, and p21 proteins increased and phospho-pRb protein expression decreased after ovarian tissue cryopreservation. Ovarian tissue cryopreservation and transplantation is regarded as one of promising options for fertility preservation. However, clinicians and researchers should be aware of possible irreversible DNA changes such as shortening of telomere length and alterations of other senescence markers in human ovarian tissues.


International Committee for Monitoring Assisted Reproductive Technologies world report: assisted reproductive technology, 2014

Abstract:
STUDY QUESTION: What were the utilization, effectiveness and safety of practices in assisted reproductive technologies (ART) globally in 2014 and what global trends could be observed?

SUMMARY ANSWER: The estimated total number of ART cycles conducted in 76 participating countries in 2014 was 1.93 million representing ∼66% of global activity, with 5-year trends including an increase in success rates and proportion of frozen embryo transfer (FET) cycles, improvement in cumulative live birth rates per aspiration, a continued increase in single embryo transfer (SET) and thus a reduction in multiple birth rates, an increase in preimplantation genetic testing and stabilization in the use of intracytoplasmic sperm injection (ICSI).

WHAT IS KNOWN ALREADY: ART is widely practiced throughout the world but continues to be characterized by significant disparities in utilization, practice, effectiveness and safety. The International Committee for Monitoring Assisted Reproductive Technologies (ICMART) annual world report series provides an important instrument for tracking trends in ART treatment and for providing clinical and public health data to ART professionals, health authorities, patients and the general public.

STUDY DESIGN, SIZE, DURATION: A retrospective, cross-sectional survey on ART procedures performed globally during 2014 was carried out. A new method for calculating ART utilization rates and number of babies born was introduced in this latest ICMART world report.

PARTICIPANTS/MATERIALS, SETTING, METHODS: Overall, 76 countries and 2 746 ART centres submitted data through national and regional ART registries on ART cycles performed during 2014 and their treatment and pregnancy outcomes. ART cycles and outcomes are described at a country level, regionally and globally. Aggregate country data are processed and analyzed based on methods developed by ICMART.

MAIN RESULTS AND THE ROLE OF CHANCE: A total of 1 629 179 ART cycles were reported for the treatment year 2014. After imputing data for missing values and non-reporting centres in reporting countries, an estimated 1 929 905 cycles resulted in >439 039 babies in reporting countries. From 2010 to 2014, the number of reported non-donor aspirations and FET cycles increased by 37.3% and 67.5%, respectively. The proportion of women aged ≥40 years undergoing non-donor ART increased from 23.2% in 2010 to 27.0% in 2014. ICSI, as a percentage of non-donor aspiration cycles, remained relatively stable at 64.8%. The IVF/ICSI combined delivery rates per fresh aspiration and FET cycle were 19.9% and 24.3%, respectively. In fresh non-donor cycles, SET increased from 30.0% in 2010 to 40.0% in 2014, while the average number of transferred embryos decreased from 1.95 to 1.73-but with wide country variation. The rate of twin deliveries following fresh non-donor transfers continued to decrease, from 20.4% in 2010 to 16.2% in 2014, and the triplet rate decreased from 1.1% to 0.5%. In FET non-donor cycles in 2014, the SET rate was 61.6%, with an average of 1.43 embryos transferred, resulting in twin and triplet rates of 10.1% and 0.2%, respectively. The cumulative delivery rate per aspiration increased from 27.1% in 2010 to 32.1% in 2014. The overall perinatal mortality rate per 1 000 births was 19.4 following fresh IVF/ICSI cycles and 9.5 following FET cycles. Among reporting countries, oocyte donation cycles represented 7.3% of all embryo transfers (89 751 transfer cycles) and resulted in 39 278 babies.

LIMITATIONS, REASONS FOR CAUTION: The data presented are dependent on the quality and completeness of data submitted by individual countries to ICMART directly or through regional registries. This report covers approximately two-thirds of world ART activity. China is a major contributor of global cycles missing from this report. Continued efforts to improve the quality and consistency of ART data reported by registries are still needed, including the use of internationally agreed standard definitions (The International Glossary of Infertility and Fertility Care). A new method was introduced in this report to calculate ART utilization and number of babies born following ART; therefore, these results are not directly comparable with previous reports.

WIDER IMPLICATIONS OF THE FINDINGS: The ICMART world reports provide the most comprehensive global statistical census and review of ART utilization, effectiveness, safety and quality. While ART treatment effectiveness and safety continue to increase globally, the wide disparities in access to treatment, procedures performed and embryo transfer practices warrant attention by clinicians and policymakers. The new method for estimating ART utilization and number of babies born provided more conservative estimates compared to the previuos method.

International Committee for Monitoring Assisted Reproductive Technologies (ICMART): world report on assisted reproductive technologies, 2013

Abstract:
OBJECTIVE: To report the utilization, effectiveness, and safety of practices in assisted reproductive technology (ART) globally in 2013 and assess global trends over time.

DESIGN: Retrospective, cross-sectional survey on the utilization, effectiveness, and safety of ART procedures performed globally during 2013.

SETTING: Seventy-five countries and 2,639 ART clinics.

PATIENT(S): Women and men undergoing ART procedures.

INTERVENTION(S): All ART.

MAIN OUTCOME MEASURE(S): The ART cycles and outcomes on country-by-country, regional, and global levels. Aggregate country data were processed and analyzed based on methods developed by the International Committee for Monitoring Assisted Reproductive Technology (ICMART).

RESULT(S): A total of 1,858,500 ART cycles were conducted for the treatment year 2013 across 2,639 clinics in 75 participating countries with a global participation rate of 73.6%. Reported and estimated data suggest 1,160,474 embryo transfers (ETs) were performed resulting in >344,317 babies. From 2012 to 2013, the number of reported aspiration and frozen ET cycles increased by 3% and 16.4%, respectively. The proportion of women aged >40 years undergoing nondonor ART increased from 25.2% in 2012 to 26.3% in 2013. As a percentage of nondonor aspiration cycles, intracytoplasmic sperm injection (ICSI) was similar to results for 2012. The in vitro fertilization (IVF)/ICSI combined delivery rates per fresh aspiration and frozen ET cycles were 24.2% and 22.8%, respectively. In fresh nondonor cycles, single ET increased from 33.7% in 2012 to 36.5% in 2013, whereas the average number of transferred embryos was 1.81-again with wide country variation. The rate of twin deliveries after fresh nondonor transfers was 17.9%; the triplet rate was 0.7%. In frozen ET cycles performed in 2013, single ET was used in 57.6%, with an average of 1.49 embryos transferred and twin and triplet rates of 10.8% and 0.4%, respectively. The cumulative delivery rate per aspiration was 30.4%, similar to that in 2012. Perinatal mortality rate per 1,000 births was 22.2% after fresh IVF/ICSI and 16.8% after frozen ET. The data presented depended on the quality and completeness of the data submitted by individual countries. This report covers approximately two-thirds of world ART activity. Continued efforts to improve the quality and consistency of reporting ART data by registries are still needed.

CONCLUSION(S): Reported ART cycles, effectiveness, and safety increased between 2012 and 2013 with adoption of a better method for estimating unreported cycles.

Abstract:
Androgenic Polycystic Ovary Syndrome (PCOS) creates physical/emotional burdens in 4-20% of premenopausal women living with PCOS (WLWP) including: few menstruations per year, subfertility, hirsutism/acne and low quality of life by validated PCOS Questionnaire (PCOSQ). Combined hormonal contraceptives (CHC), the current standard-of-care, improve PCOSQ only 16%; with stopping CHC, benefits disappear within 6-months. We hypothesize too-fast brain/luteinizing hormone (LH) pulses cause PCOS. Progesterone (P4) slows LH when testosterone (FreeT) is normal. Combining two approved medications, Cyclic P4 with anti-androgen, Spironolactone (Sp), will likely provide effective, durable benefits. WLWP lit-review suggested significant P4 7-14-day benefits. A 6-month prospective feasibility study of CyclicP4/Sp is necessary. Overall purpose: Perform a pilot study in 40 WLWP on Cyclic P4 (300 mg/bedtime, 14 days/month) plus Spironolactone (Sp, 200 mg/d). Feasibility: Assess longitudinal within-WLWP 6-month changes in: 1) PCOSQ; 2) FreeT, HbA1c, and LH; plus 3) WLWP's acceptance of CyclicP4/Sp.

Methods: Single-centre, prospective, longitudinal single cohort study. Recruit \~7-8 WLWP/month over 4-6 months; 85% retention. Eligible WLWP have physician-diagnosed PCOS, are 1-month off CHC/metformin, ages 19-35 (avoiding adolescence/perimenopause), HbA1c <6.4% (no diabetes) and commit to non-hormonal contraception, if needed. Recruitment uses online, internet, strategic ads and tear-tab posters. Measures at 0 and 6 months: as above plus K+ (safety assessment). Menstrual Cycle Diary monitoring (flow, adherence), 2 visits, monthly telephone/emails for support and assessment of any adverse effects. Statistical analysis: changes by paired T-test.
Summary: A feasibility 6-month study of CyclicP4/Sp will facilitate a CIHR-funded RCT of CHC versus this innovative and likely beneficial treatment for WLWP.


Prevalence of hormone-related mood disorder symptoms in women with ADHD

Abstract: This is the first study to assess the prevalence of symptoms of premenstrual dysphoric disorder (PMDD), episodes of postpartum depression symptoms (PPD) after first childbirth, and climacteric mood symptoms in Attention-Deficit/Hyperactivity Disorder (ADHD). 209 consecutive women (18-71 years) with ADHD completed the PMDD chapter of the Neuropsychiatric Interview Plus version 5.0.0 to assess PMDD, the Edinburgh Postnatal Depression Scale to assess PPD, and the Greene Climacteric Scale to assess climacteric symptoms. Comorbid psychiatric disorders, medication use, and chronobiological sleep characteristics were also assessed. The prevalence of PMDD and PPD were high in ADHD, compared to the general population. PMDD symptoms were associated with less use of contraceptives. Antidepressants were associated with more PMDD symptoms. The following GCS scores were significant increased: anxiety, depression, and sexual dysfunction, vasomotor and somatic complaints. No significant differences were found in sleep characteristics or current comorbidity between the groups with and without PPD or PMDD, or increased climacteric scores. The prevalences of PMDD, PPD and climacteric scores were high in women with ADHD. This is the first study in women with ADHD that suggests that female ADHD patients suffer from significant PMDD symptoms, experience PPD during the first child birth, and experience more severe climacteric symptoms.
