Best Practice Recommendations for Infertility Management.

Aim: The objective of this document is to provide guidance to the infertility specialist, gynecologist, embryologist, and counselors on the management of sub-fertility and brief them with the recent advances in the field. These recommendations will aid the aforementioned healthcare professionals in everyday clinical decisions about appropriate and effective care of their patients with the best available evidence. Participants: Extensive deliberations, discussion, and brainstorming was done between different reproductive medicine (RM) specialists, to develop the recommendations. Evidence: A systematic review of the literature published up to June 2019 was carried out using PubMed and Cochrane Collaboration Library. International guidelines, cohort studies, case series, observational studies, and randomized controlled trials currently available in the literature were reviewed. Indian data whatever available was also reviewed. Process: Primary meetings were held with leading reproductive medicine specialists. Each topic was brainstormed on by a group of reproductive medicine experts, who then prepared the first draft of the recommendation. These recommendations then were reviewed by Dr. Jaideep Malhotra, Dr. Gouri Devi, and Dr. Madhuri Patil along with the chief co-ordinator of each consensus to finalize the final draft. Conclusions: From the literature and discussion of the available evidence, several topics were identified for which evidence is inconsistent, insufficient, or non-existing. For the benefit of couples undergoing several treatments, the working committee recommends that future research, where possible in well-designed RCTs, will help in establishing evidence for a particular practice. In the Indian context, one also needs to take into consideration facilities and options available, cost, lack of insurance coverage, experimental nature of some advanced techniques used.

FIGO statement: Fertility preservation.

Fertility preservation is a growing field in reproductive medicine that may raise ethical questions. Preservation of fertility must be discussed with the patient if gonadotoxic treatment is required, whether in the case of benign or malignant pathology, or in the management of transgender identity. As a result, surgery or chemotherapy that has fewer adverse impacts on fertility should be proposed if this does not alter the prognosis of the disease. If the risk of infertility persists, then fertility cryopreservation should be proposed for children and adults of reproductive age. Sperm, oocytes, and gonadal tissue can be cryopreserved for many years. FIGO wishes to emphasize the importance of fertility preservation in the medical and surgical management of patients, and the importance of a specialized, multidisciplinary approach.

The challenges of obesity for fertility: A FIGO literature review.

Obesity has been linked to infertility through several mechanisms, including at a molecular level. Those living with obesity face additional barriers to accessing fertility treatments and achieving a successful pregnancy, which can contribute to their economic and psychosocial stressors. There is scope to further improve care for people living with obesity and infertility with empathy, via a multidisciplinary approach.

Effect of Reproductive and Lifestyle Factors on Anti-Mullerian Hormone Levels in Women of Indian Origin.

Background: Infertility is a world-wide problem and one third females. Over the years, anti-mullerian hormone (AMH) has emerged as a major marker of ovarian reserve. There is also increasing interest in determining the factors which can impact AMH levels. Aims: To correlate the association of reproductive and lifestyle factors on AMH levels in women of Indian origin. Settings and Design: Multicentric cross sectional study. Materials and Methods: The study was conducted using data extracted from the patient records of seven private fertility practices located in North India. Women who were attending these clinics for fertility treatment were requested to fill the questionnaire related to reproductive and lifestyle factors. Statistical Analysis used: Our outcome variable was level of AMH measured in the past 3 months, and was assessed as normal or low. All analyses were conducted using STATA 17. Results: We found a direct association of low AMH with increasing age, short cycles, amenorrhea and women with family history of premature menopause. We found a direct correlation of high AMH and women with polycystic ovary syndrome and those whose partners had Oligoasthenoteratozoospermia (OATS) or azoospermia. There was no correlation with smoking, sleep, diet, body mass index, cell phone or laptop use in our study. Conclusion: Reproductive and lifestyle factors may affect ovarian reserve and but there was a dearth of human studies in this area. To the best of our knowledge this is the first human study on the effect of AMH on Laptop and Cell phone use. We urgently need more studies to confirm or refute our findings so that we can counsel our patients well.

Clinical practice recommendations for the detection and management of hyperglycemia in pregnancy from South Asia, Africa and Mexico during COVID-19 pandemic.

The human coronavirus disease 2019 (COVID-19) pandemic has affected overall healthcare delivery, including prenatal, antenatal and postnatal care. Hyperglycemia in pregnancy (HIP) is the most common medical condition encountered during pregnancy. There is little guidance for primary care physicians for providing delivery of optimal perinatal care while minimizing the risk of COVID-19 infection in pregnant women. This review aims to describe pragmatic modifications in the screening, detection and management of HIP during the COVID- 19 pandemic. In this review, articles published up to June 2021 were searched on multiple databases, including PubMed, Medline, EMBASE and ScienceDirect. Direct online searches were conducted to identify national and international guidelines. Search criteria included terms to extract articles describing HIP with and/or without COVID-19 between 1st March 2020 and 15th June 2021. Fasting plasma glucose, glycosylated hemoglobin (HbA1c) and random plasma glucose could be alternative screening strategies for gestational diabetes mellitus screening (at 24-28 weeks of gestation), instead of the traditional 2 h oral glucose tolerance test. The use of telemedicine for the management of HIP is recommended. Hospital visits should be scheduled to coincide with obstetric and ultrasound visits. COVID-19 infected pregnant women with HIP need enhanced maternal and fetal vigilance, optimal diabetes care and psychological support in addition to supportive measures. This article presents pragmatic options and approaches for primary care physicians, diabetes care providers and obstetricians for GDM screening, diagnosis and management during the pandemic, to be used in conjunction with routine antenatal care.

Indian Society for Assisted Reproduction Consensus Guidelines on Preimplantation Genetic Testing in In vitro Fertilization Clinics.

STUDY QUESTION: What are the good practice guidelines for Pre implantation genetic testing applicable in INDIA? WHAT IS ALREADY KNOWN: Pre-Implantation Genetic Testing (PGT) is not new in India. It is used to identify euploid embryos for transfer, thus enabling couples to achieve a healthy pregnancy. There has been a lot of controversy surrounding PGT in the international forums; most of these debates have failed to reach a consensus on whether PGT should be offered or its concerns be validated more.

Prevention of noncommunicable diseases by interventions in the preconception period: A FIGO position paper for action by healthcare practitioners.

With the increase in obesity prevalence among women of reproductive age globally, the risks of type 2 diabetes, gestational diabetes, pre-eclampsia, and other conditions are rising, with detrimental effects on maternal and newborn health. The period before pregnancy is increasingly recognized as crucial for addressing weight management and reducing malnutrition (both under- and overnutrition) in both parents to reduce the risk of noncommunicable diseases (NCDs) in the mother as well as the passage of risk to her offspring. Healthcare practitioners, including obstetricians, gynecologists, midwives, and general practitioners, have an important role to play in supporting women in planning a pregnancy and achieving healthy nutrition and weight before pregnancy. In this position paper, the FIGO Pregnancy Obesity and Nutrition Initiative provides an overview of the evidence for preconception clinical guidelines to reduce the risk of NCDs in mothers and their offspring. It encourages healthcare practitioners to initiate a dialogue on women's health, nutrition, and weight management before conception. While acknowledging the fundamental importance of the wider social and environmental determinants of health, this paper focuses on a simple set of recommendations for clinical practice that can be used even in short consultations. The recommendations can be contextualized based on local cultural and dietary practices as part of a system-wide public health approach to influence the wider determinants as well as individual factors influencing preconception health.

Indian National Association for the Study of the Liver-Federation of Obstetric and Gynaecological Societies of India Position Statement on Management of Liver Diseases in Pregnancy.

Liver diseases occurring during pregnancy can be serious and can progress rapidly, affecting outcomes for both the mother and fetus. They are a common cause of concern to an obstetrician and an important reason for referral to a hepatologist, gastroenterologist, or physician. Liver diseases during pregnancy can be divided into disorders unique to pregnancy, those coincidental with pregnancy, and preexisting liver diseases exacerbated by pregnancy. A rapid differential diagnosis between liver diseases related or unrelated to pregnancy is required so that specialist and urgent management of these conditions can be carried out. Specific Indian guidelines for the management of these patients are lacking. The Indian National Association for the Study of the Liver (INASL) in association with the Federation of Obstetric and Gynaecological Societies of India (FOGSI) had set up a taskforce for development of consensus guidelines for management of patients with liver diseases during pregnancy, relevant to India. For development of these guidelines, a two-day roundtable meeting was held on 26-27 May 2018 in New Delhi, to discuss, debate, and finalize the consensus statements. Only those statements that were unanimously approved by most members of the taskforce were accepted. The primary objective of this review is to present the consensus statements approved jointly by the INASL and FOGSI for diagnosing and managing pregnant women with liver diseases. This article provides an overview of liver diseases occurring in pregnancy, an update on the key mechanisms involved in its pathogenesis, and the recommended treatment options.

Effect of the combined oral contraceptive pill and/or metformin in the management of polycystic ovary syndrome: A systematic review with meta-analyses.

BACKGROUND: Polycystic ovary syndrome (PCOS) has a prevalence of 8%-13%. Given the prevalence, diverse health impacts and variation in care, rigorous evidence-based guidelines are needed in PCOS management. This systematic review with meta-analyses aimed to investigate the effect of the combined oral contraceptive pill (COCP) and/or metformin in the management of hormonal and clinical features of PCOS, to inform international guidelines. METHODS: Electronic databases were searched systematically from inception until 11 January 2017 to inform the guideline process. Eligible studies were randomized controlled trials which investigated the effect of COCPs and/or metformin alone or combined on hormonal and clinical features in women with PCOS. Outcomes were prioritized as critical for informing a decision about an intervention or important or not important, according to GRADE. Articles were assessed by one author against selection criteria, in consultation with a second author. Data were double extracted independently by four authors, and data quality appraisal was completed. Meta-analyses were conducted, where appropriate. RESULTS: Fifty-six studies were eligible for inclusion. Outcomes prioritized by women and health professionals included the following: irregular cycles, insulin resistance, weight, BMI, thromboembolic events and gastrointestinal effects. In low-quality evidence in adolescents, meta-analyses demonstrated that metformin was better than COCP for BMI (mean difference [MD] -4.02 [-5.23, -2.81], P < 0.001); COCP was better than metformin for menstrual regulation (MD -0.19 [-0.25, -0.13], P < 0.00001). In low-quality evidence in adults, meta-analyses demonstrated that metformin was better than placebo for BMI (MD -0.48 [-0.94, -0.02], P = 0.04); metformin was better than COCP for fasting insulin (MD 4.00 [2.59, 5.41], P = 0.00001), whereas COCP was better than metformin for irregular cycles (MD 12.49 [1.34, 116.62], P = 0.03). Combined oral contraceptive pill alone was better than the combination with an anti-androgen for BMI (MD -3.04 [-5.45, -0.64], P = 0.01). Metformin was associated with generally mild gastrointestinal adverse events. Differences in statistical significance were observed when outcomes were subgrouped by BMI. CONCLUSIONS: This review identified that COCP therapy has benefits for management of hyperandrogenism and menstrual regulation. Metformin combined with the COCP may be useful for management of metabolic features. There is minimal evidence of benefits of adding an anti-androgen to COCP therapy. Metformin alone has benefits for adult women for management of weight, hormonal and metabolic outcomes, especially for women with BMI ≥ 25 kg/m2 . There is inadequate evidence to suggest the optimal COCP formulation, or dosing regimen and formulation of metformin.

Dose-response and Cardiopulmonary Side Effects of the Novel Neuromuscular-blocking Drug CW002 in Man.

BACKGROUND: CW002 is a benzylisoquinolinium nondepolarizing neuromuscular-blocking drug found to be inactivated by cysteine in preclinical studies. The current study represents a dose escalation clinical trial designed to describe CW002 potency, duration, cardiopulmonary side effects, and histamine release. METHODS: Healthy subjects anesthetized with sevoflurane/nitrous oxide were divided into five groups (n = 6), each receiving a fixed CW002 dose (0.02, 0.04, 0.06, 0.08, or 0.10 mg/kg), and one group (n = 4) receiving 0.14 mg/kg. Blood pressure and heart rate were continuously recorded along with airway dynamic compliance. Neuromuscular blockade was assessed with mechanomyography at the adductor pollicis. Arterial blood was obtained before and after CW002 injection for analysis of plasma histamine concentration. Potency was estimated from a baseline sigmoid Emax model. RESULTS: ED50 was found to be 0.036 mg/kg (95% CI, 0.020 to 0.053 mg/kg) and ED95 0.077 mg/kg (95% CI, 0.044 to 0.114 mg/kg). At 0.14 mg/kg (1.8 × ED95), 80% twitch depression occurred in 94 ± 18 s with complete block in 200 ± 87 s. Clinical recovery (25% of maximum twitch) occurred in 34 ± 3.4 min, with a 5 to 95% recovery interval of 35.0 ± 2.7 min. The time to a train-of-four ratio greater than 0.9 ranged from 59 to 86 min. CW002 did not elicit histamine release or significant (greater than 10%) changes in blood pressure, heart rate, or dynamic airway compliance. CONCLUSIONS: In healthy subjects receiving sevoflurane/nitrous oxide, CW002 at 1.8 × estimated ED95 produces a clinical duration less than 40 min, elicits no histamine release, and has minimal cardiopulmonary side effects.

Preclinical Pharmacology of CW002: A Nondepolarizing Neuromuscular Blocking Drug of Intermediate Duration, Degraded and Antagonized by l-cysteine-Additional Studies of Safety and Efficacy in the Anesthetized Rhesus Monkey and Cat.

BACKGROUND: CW002, a novel nondepolarizing neuromuscular blocking agent of intermediate duration, is degraded in vitro by L-cysteine; CW002-induced neuromuscular blockade (NMB) is antagonized in vivo by exogenous L-cysteine. Further, Institutional Animal Care and Use Committee-approved studies of safety and efficacy in eight anesthetized monkeys and six cats are described. METHODS: Mean arterial pressure, heart rate, twitch, and train-of-four were recorded; estimated dose producing 95% twitch inhibition (ED95) for NMB and twitch recovery intervals from 5 to 95% of baseline were derived. Antagonism of 99 to 100% block in monkeys by L-cysteine (50 mg/kg) was tested after bolus doses of approximately 3.75 to 20 × ED95 and after infusions. Vagal and sympathetic autonomic responses were recorded in cats. Dose ratios for [circulatory (ED20) or autonomic (ED50) changes/ED95 (NMB)] were calculated. RESULTS: ED95s of CW002 in monkeys and cats were 0.040 and 0.035 mg/kg; L-cysteine readily antagonized block in monkeys: 5 to 95% twitch recovery intervals were shortened to 1.8 to 3.6 min after 3.75 to 10 × ED95 or infusions versus 11.5 to 13.5 min during spontaneous recovery. ED for 20% decrease of mean arterial pressure (n = 27) was 1.06 mg/kg in monkeys; ED for 20% increase of HR (n = 27) was 2.16 mg/kg. ED50s for vagal and sympathetic inhibition in cats were 0.59 and >>0.80 mg/kg (n = 14 and 15). Dose ratios for [circulatory or autonomic changes/ED95 (NMB)] were all more than 15 × ED95. CONCLUSIONS: The data further verify the neuromuscular blocking properties of CW002, including rapid reversal by L-cysteine of 100% NMB under several circumstances. A notable lack of autonomic or circulatory effects provided added proof of safety and efficacy.

Open-label, Prospective, Investigator Initiated Study to Assess the Clinical Role of Oral Natural or Synthetic Progesterone During Stimulated IUI Cycles for Unexplained Infertility.

BACKGROUND: Unexplained infertility remains as one of the important subtype of infertility that follows expectant management with Intrauterine Insemination (IUI) in most cases. AIM: To evaluate the clinical role of progesterone supplement as luteal phase support for women with unexplained infertility following stimulation protocol with Clomiphene Citrate (CC)/Human Menopausal Gonadotropin (HMG). MATERIALS AND METHODS: An investigator initiated study to survey the success rate for first cycle of IUI following stimulation protocol with CC/HMG & luteal phase support with oral natural or synthetic progesterone was conducted. 120 patient records between observation period of Jan to May '14 were retrieved especially for subjects undergoing IUI procedure for Unexplained infertility. Patients with baseline Serum (Sr). progesterone records who received Oral Natural Micronized Progesterone Sustained Release (Oral NMP SR) (N=45) or Dydrogesterone (n=33) following CC/HMG induction protocol and human Chorionic Gonadotropin(HCG) Inj., were further analysed following Luteal Phase Support(LPS) with oral natural or synthetic progesterone. RESULTS: Baseline demographics showed 78 patients with mean age, weight and cycle duration of 29.5 yrs, 57.3 kg & 28.6 days respectively. Progesterone was supplemented as Oral NMP SR 200/300 mg OD or Dydrogesterone 10 mg bid in 22, 23 and 33 patients respectively. In all cases ovulation was triggered with HCG inj., followed by IUI within the next 48 hours while baseline sr. progesterone levels were being assessed. Medicines and Healthcare Products Regulatory Agency (MHRA) UK recommended therapeutic compliance to suggest sr. progesterone levels of ≥14ng/ml were recorded as Mid-luteal levels in all of these patients. This therapeutic compliance was noted in 82.2% & 78.8% of the patients treated with oral NMP SR or Dydrogesterone respectively. Pregnancy was observed amongst 5 and 10 patients treated with oral NMP SR and Dydrogesterone respectively at the end of 'First' IUI cycle. Both the groups were well tolerated with drowsiness documented in three cases for Oral NMP SR. CONCLUSION: Clinical supplementation with ONMPSR suggests therapeutic compliance and alternative strategy to conventional formulations while offering dosing convenience with minimal side effects.

Recommendations on routine mid-trimester anomaly scan.

The purpose of this paper is to discuss the minimal requirements of the routine mid-trimester anomaly scan in Asian countries after taking into account various factors, including local circumstances, medical practice, guidelines, and availability of experienced sonographers and high-resolution ultrasound machines, which affect the prenatal detection rate of fetal anomalies. In general, a routine mid-trimester anomaly scan includes the assessment of the number of fetuses, fetal cardiac activity, size, anatomy, liquor and placental location. The most controversial issue is which fetal structures should at least be examined. We discussed the requirements of a basic routine scan, as well as the optional views, which can be obtained if feasible to improve the detection of fetal, placental or maternal abnormalities. Routine anomaly scan remains a clinical challenge.

NHE isoform switching and KChIP2 upregulation in aging porcine atria.

Aging increases the risk of cardiac pathologies including atrial fibrillation and can alter myocardial responsiveness to therapeutic agents. Here, seeking molecular correlates of myocardial aging processes, we performed global "whole transcript" analysis of 25,388 genes using 572,667 probes to compare the left atrial (LA) transcriptomes of young adult (9 months old) versus elderly (10 years old) female swine. NHE2 (>9-fold) and KChIP2 (3.8-fold) exhibited the highest aging-related expression increases. Real-time qPCR recapitulated these findings and indicated a 50% decrease in LA NHE1, a twofold increase in right atrial KChIP2, but no significant changes for these transcripts in either ventricle. Notably, even in young adult pigs, NHE2 transcript was detectable and enriched in the atria over the ventricles. NHE1, the recognized cardiac isoform of the sodium hydrogen exchanger, has proven a compelling but clinically disappointing therapeutic target with respect to reperfusion arrhythmias. Our data challenge the dogma that NHE1 is alone in the myocardium and suggest that NHE2 could negatively impact the pharmacological responsiveness of atrial tissue to NHE1-specific inhibitors. KChIP2 is a cytosolic ß subunit essential for generation of I to. The increased KChIP2 expression we observed with aging substantially shortened in silico atrial myocyte action potential duration, a predisposing factor in atrial fibrillation. Consistent with this, 4/5 elderly swine sustained pacing-induced AF≥15 s after cessation of stimulation, compared to 0/3 young swine. Our findings uncover potential molecular bases for increased arrhythmogenicity and reduced pharmacologic efficacy in the aging atrium, in a large animal model of human cardiac physiology.

Assisted reproduction in polycystic ovarian disease: A multicentric trial in India.

AIM: The aim of this study is to compare ovarian response, oocyte, embryo quality, ovarian hyperstimulation syndrome incidence, and pregnancy rates in polycystic ovary syndrome (PCOS) and non-PCOS group. MATERIALS AND METHODS: This was a prospective observational study on PCOS carried out in seven assisted reproduction centers in India between August 2008 and July 2010, as part of trial under the Indian Society of Assisted Reproduction. A total of 192 women (77 in the PCOS group and 115 in the non- PCOS group) undergoing in vitro fertilization/intracytoplasmic sperm injection were included. All women had long protocol and recombinant follicle-stimulating hormone stimulation. ANALYSIS: The mean number of follicles and oocytes was higher in PCOS group compared with non-PCOS, being 27.2 (±8.8) and 13.6 (±5.3); 15.9 (±6.3) and 10.9 (±6.2), respectively. The recovery rates of oocytes and mature oocytes per follicle were less in the PCOS group which was 64% and 61.1%, respectively as opposed to 80.3% and 74.5%, respectively in non-PCOS group. The total numbers of top-quality embryos were less in the PCOS group. CONCLUSION: In PCOS women though the number of follicles was more, recovery of mature oocytes, top-quality embryos was less. Pregnancy rates were comparable in both groups.

Transcriptomic analysis reveals atrial KCNE1 down-regulation following lung lobectomy.

Lone atrial fibrillation (AF) is associated with various ion channel gene sequence variants, notably the common S38G loss-of-function polymorphism in the KCNE1 K(+) channel ancillary subunit gene. New-onset postoperative AF (POAF) generally occurs 48-72 h after major surgery, particularly following procedures within the chest, but its molecular bases remain poorly understood. To begin to address this gap in knowledge, we analyzed molecular changes in the left atrium (LA) in relation to simultaneous changes in hemodynamics, LA effective refractory period (ERP), and the capacity to sustain electrically-induced AF following left upper lung lobectomy in swine. Relative to control pigs (no previous surgery), 3 days after lobectomy higher values for mean pulmonary artery pressure (16 ± 1 vs 22 ± 2 mmHg; P=0.045) and pulmonary vascular resistance (273 ± 47 vs 481 ± 63 dyns/cm(5); P=0.025) were evident, whereas other hemodynamic variables were unchanged. LA ERP trended toward reduction in lobectomy animals (187 ± 16 vs 170 ± 20 ms, P>0.05). None of the lobectomy pigs developed spontaneous POAF as assessed by telemetric ECG. However, all lobectomy pigs, but none of the controls, were able to sustain AF induced by a 10s burst of rapid pacing for ≥ 30 s (P=0.0079), independent of LA ERP; AF was sustained ≥ 60s in 3/5 postoperative pigs versus 0/5 controls and correlated with a shorter ERP overall (P=0.023). Transcriptomic analysis of LA tissue revealed 23 up-regulated and 10 down-regulated transcripts (≥ 1.5-fold, P<0.05) in lobectomy pigs. Strikingly, of the latter, KCNE1 down-regulation showed the statistically strongest link to surgery (2.0-fold, P=0.009), recapitulated at the protein level with Western blotting (P=0.039), suggesting KCNE1 down-regulation as a possible common mechanistic factor in POAF and lone AF. Of the up-regulated transcripts, while Teneurin-2 was the strongest linked (1.5-fold change, P=0.001), DSCR5 showed the highest induction (2.7-fold, P=0.02); this and other hits will be targeted in future functional studies.
