Semaglutide Alleviates Ovary Inflammation via the AMPK/SIRT1/NF‑κB Signaling Pathway in Polycystic Ovary Syndrome Mice. Drug Des Devel Ther 2024; 18:3925-3938. [PMID: 39247793 PMCID: PMC11380913 DOI: 10.2147/dddt.s484531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2024] [Accepted: 08/26/2024] [Indexed: 09/10/2024] Open
Abstract
Background GLP-1 receptor agonists (GLP-1 RA) have been proven to treat several metabolic diseases; however, the effects of GLP-1 RA on polycystic ovary syndrome (PCOS) remain unclear. Here, we aimed to investigate whether semaglutide, a novel GLP-1 RA, could alleviate ovarian inflammation in PCOS mice. Methods Female C57BL/6J mice were subcutaneously injected with dehydroepiandrosterone for 21 days to establish the PCOS model. Then the mice were randomly divided into three groups: PCOS group (n = 6), S-0.42 group (semaglutide 0.42 mg/kg/w, n = 6), and S-0.84 group (semaglutide 0.84 mg/kg/w, n = 6). The remaining six mice were used as controls (NC). After 28 days of intervention, serum sex hormones and inflammatory cytokine levels were measured. Hematoxylin and eosin staining was used to observe the ovarian morphology. Immunohistochemical staining was used to detect the relative expression of CYP19A1, TNF-α, IL-6, IL-1β, and NF-κB in ovaries. CYP17A1 and StAR were detected using immunofluorescence staining. Finally, the relative expressions of AMPK, pAMPK, SIRT1, NF-κB, IκBα, pIκBα, TNF-α, IL-6, and IL-1β were measured using Western blotting. Results First, after intervention with semaglutide, the weight of the mice decreased, insulin resistance improved, and the estrous cycle returned to normal. Serum testosterone and IL-1β levels decreased significantly, whereas estradiol and progestin levels increased significantly. Follicular cystic dilation significantly improved. The expression of TNF-α, IL-6, IL-1β, NF-κB, CYP17A1, and StAR in the ovary was significantly downregulated, whereas CYP19A1 expression was upregulated after the intervention. Finally, we confirmed that semaglutide alleviates ovarian tissue inflammation and improves PCOS through the AMPK/SIRT1/NF-κB signaling pathway. Conclusion Semaglutide alleviates ovarian inflammation via the AMPK/SIRT1/NF‑κB signaling pathway in PCOS mice.

Impact of insulin sensitization on metabolic and fertility outcomes in women with polycystic ovary syndrome and overweight or obesity-A systematic review, meta-analysis, and meta-regression. Obes Rev 2024; 25:e13744. [PMID: 38572616 DOI: 10.1111/obr.13744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 02/16/2024] [Accepted: 02/28/2024] [Indexed: 04/05/2024]
Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive-age women. This systematic review, meta-analysis, and meta-regression aims to compare the effect of insulin sensitizer pharmacotherapy on metabolic and reproductive outcomes in women with PCOS and overweight or obesity. We searched online databases MEDLINE via OVID, EMBASE, Clinicaltrials.gov, and EudraCT for trials published from inception to November 13, 2023. Inclusion criteria were double-blind, randomized controlled trials in women diagnosed with PCOS, body mass index (BMI) ≥ 25 kg/m2, which reported metabolic or reproductive outcomes. The intervention was insulin sensitization pharmacotherapy versus placebo or other agents. The primary outcomes were changes from baseline BMI, fasting blood glucose, and menstrual frequency. Nineteen studies were included in this review. Metformin had the most significant effect on the fasting plasma glucose and body mass index. Insulin sensitizer pharmacotherapy significantly reduced fasting plasma glucose, body mass index, fasting serum insulin, HOMA-IR, sex hormone binding globulin, and total testosterone, but the effect size was small. There was a lack of menstrual frequency and live birth data. The results indicate a role for insulin sensitizers in improving the metabolic and, to a lesser degree, reproductive profile in these women. Further research should examine insulin sensitizers' effects on objective measures of fecundity.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. Obesity exacerbates the reproductive complications of PCOS; however, the management of obesity in women with PCOS remains a large unmet clinical need. Observational studies have indicated that bariatric surgery could improve the rates of ovulatory cycles and prospects of fertility; however, the efficacy of surgery on ovulation rates has not yet been compared with behavioural modifications and medical therapy in a randomised trial. The aim of this study was to compare the safety and efficacy of bariatric surgery versus medical care on ovulation rates in women with PCOS, obesity, and oligomenorrhoea or amenorrhoea. METHODS In this multicentre, open-label, randomised controlled trial, 80 women older than 18 years, with a diagnosis of PCOS based on the 2018 international evidence-based guidelines for assessing and managing PCOS, and a BMI of 35 kg/m2 or higher, were recruited from two specialist obesity management centres and via social media. Participants were randomly assigned at a 1:1 ratio to either vertical sleeve gastrectomy or behavioural interventions and medical therapy using a computer-generated random sequence (PLAN procedure in SAS) by an independent researcher not involved with any other aspect of the clinical trial. The median age of the entire cohort was 31 years and 79% of participants were White. The primary outcome was the number of biochemically confirmed ovulatory events over 52 weeks, and was assessed using weekly serum progesterone measurements. The primary endpoint included the intention-to-treat population and safety analyses were per-protocol population. This study is registered with the ISRCTN registry (ISRCTN16668711). FINDINGS Participants were recruited from Feb 20, 2020 to Feb 1, 2021. 40 participants were assigned to each group and there were seven dropouts in the medical group and ten dropouts in the surgical group. The median number of ovulations was 6 (IQR 3·5-10·0) in the surgical group and 2 (0·0-4·0) in the medical group. Women in the surgical group had 2.5 times more spontaneous ovulations compared with the medical group (incidence rate ratio 2·5 [95% CI 1·5-4·2], p<0·0007). There were more complications in the surgical group than the medical group, although without long-term sequelae. There were 24 (66·7%) adverse events in the surgical group and 12 (30·0%) in the medical group. There were no treatment-related deaths. INTERPRETATION Bariatric surgery was more effective than medical care for the induction of spontaneous ovulation in women with PCOS, obesity, and oligomenorrhoea or amenorrhoea. Bariatric surgery could, therefore, enhance the prospects of spontaneous fertility in this group of women. FUNDING The Jon Moulton Charity Trust.

J Assist Reprod Genet 2024; 41:1687-1697. [PMID: 38689082 PMCID: PMC11224218 DOI: 10.1007/s10815-024-03123-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 04/15/2024] [Indexed: 05/02/2024] Open
Abstract
PURPOSE To examine the effect of bariatric surgery (BS) on obstetric and neonatal outcomes in patients with polycystic ovary syndrome (PCOS). METHODS A retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database, including women who delivered in the third trimester or had a maternal death in the USA (2004-2014). We compared obstetric and neonatal outcomes between groups in three analyses: (1) Primary analysis-women with an ICD-9 PCOS diagnosis who underwent BS compared to pregnant PCOS patients without BS. (2) Sub-group analysis-PCOS women with BS compared to obese PCOS women (body mass index (BMI) ≥ 30 kg/m2) without BS. (3) Women with and without PCOS who underwent BS. RESULT In the primary analysis, pregnant PCOS women who underwent BS (N = 141), compared to pregnant PCOS women without BS (N = 14,741), were less likely to develop pregnancy-induced hypertension (PIH) (9.2% vs. 16.2%, respectively, aOR 0.39, 95% CI 0.21-0.72) and gestational diabetes mellitus (GDM) (9.9% vs. 18.8, aOR 0.40, 95% CI 0.23-0.70). In the sub-group analysis, PCOS women with BS, compared to obese PCOS women without BS (N = 3231), were less likely to develop gestational hypertension, preeclampsia, and preeclampsia or eclampsia superimposed on hypertension (P < 0.05). Lastly, PCOS patients with BS had a higher cesarean section rate when compared to non-PCOS patients with BS (N = 9197) (61.7% vs. 49.2%, aOR 1.48, 95% CI 1.05-2.09), with otherwise comparable obstetric and neonatal outcomes. CONCLUSIONS BS in PCOS patients was associated with reduced risks for GDM and PIH when compared to PCOS controls without BS and reduced risk for gestational hypertension, preeclampsia, and preeclampsia or eclampsia superimposed on hypertension when compared to obese PCOS controls without BS. Moreover, BS was associated with reduced inherent pregnancy risks of PCOS, almost equating them to those of non-PCOS counterparts.

Abstract
This systematic review and meta-analysis evaluated the efficacy of anti-obesity agents for hormonal, reproductive, metabolic, and psychological outcomes in polycystic ovary syndrome (PCOS) to inform the 2023 update of the International Evidence-based Guideline on PCOS. We searched Medline, EMBASE, PsycInfo, and CINAHL until July 2022 with a 10-year limit to focus on newer agents. Eleven trials (545 and 451 participants in intervention and control arms respectively, 12 comparisons) were included. On descriptive analyses, most agents improved anthropometric outcomes; liraglutide, semaglutide and orlistat appeared superior to placebo for anthropometric outcomes. Meta-analyses were possible for two comparisons (exenatide vs. metformin and orlistat + combined oral contraceptive pill [COCP] vs. COCP alone). On meta-analysis, no differences were identified between exenatide versus metformin for anthropometric, biochemical hyperandrogenism, and metabolic outcomes, other than lower fasting blood glucose more with metformin than exenatide (MD: 0.10 mmol/L, CI 0.02-0.17, I2 = 18%, 2 trials). Orlistat + COCP did not improve metabolic outcomes compared with COCP alone (fasting insulin MD: -8.65 pmol/L, -33.55 to 16.26, I2 = 67%, 2 trials). Published data examining the effects of anti-obesity agents in women with PCOS are very limited. The role of these agents in PCOS should be a high priority for future research.

The impact of metformin on weight and metabolic parameters in patients with obesity: A systematic review and meta-analysis of randomized controlled trials. Diabetes Obes Metab 2024; 26:1850-1867. [PMID: 38468148 DOI: 10.1111/dom.15501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 01/15/2024] [Accepted: 01/30/2024] [Indexed: 03/13/2024]
Abstract
There are conflicting data on the weight-reducing potential of metformin (MTF) in nondiabetic patients with obesity. The purpose of this systematic review and meta-analysis was to evaluate the effect of MTF on weight and cardiometabolic parameters in adults with overweight/obesity with or without nonalcoholic fatty liver disease (NAFLD) (CRD42018085512). We included randomized controlled trials (RCTs) in adults without diabetes mellitus, with mean body mass index (BMI) ≥ 25 kg/m2, with or without NAFLD, comparing MTF to placebo/control, lifestyle modification (LSM) or a US Food and Drug Administration-approved anti-obesity drug, reporting on weight or metabolic parameters, and extending over at least 3 months. We conducted a systematic search in MEDLINE, EMBASE, PubMed and the Cochrane Library without time limitation (until March 2022). We screened and selected eligible articles, abstracted relevant data, and assessed the risk of bias. All steps were in duplicate and independently. We conducted a random-effects model meta-analysis using Review Manager version 5.3, with prespecified subgroup analyses in case of heterogeneity. We identified 2650 citations and included 49 trials (55 publications). Compared to placebo, MTF was associated with a significant reduction in BMI (mean difference [MD] -0.56 [-0.74, -0.37] kg/m2; p < 0.0001), at doses ranging from 500 to 2550 mg/day, and with a significant percentage change in BMI of -2.53% (-2.90, -2.17) at the dose 1700 mg/day. There was no interaction by baseline BMI, MTF dose or duration, nor presence or absence of NAFLD. There was no significant difference between MTF and LSM. Orlistat was more effective than MTF (at doses of 1000-1700 mg/day) in terms of weight loss, with an MD in BMI of -3.17 (-5.88; -0.47) kg/m2, favouring the former. Compared to placebo/control, MTF improved insulin parameters, while no effect was detected when compared to LSM. A few small trials showed heterogenous effects on liver parameters in patients with NAFLD treated with MTF compared to placebo/control. There was a large variability in the expression of outcome measures and RCTs were of low quality. In conclusion, MTF was associated with a modest weight reduction in obese nondiabetic patients. Further high-quality and better powered studies are needed to examine the impact of MTF in patients with insulin resistance and NAFLD.

Effect of SGLT2 Inhibitors on Improving Glucolipid Metabolism and Reproductive Hormone Status in Overweight/Obese Women with PCOS: A Systematic Review and Meta-Analysis. Reprod Sci 2024; 31:1190-1203. [PMID: 38057530 DOI: 10.1007/s43032-023-01415-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 11/20/2023] [Indexed: 12/08/2023]
Abstract
BACKGROUND Obesity, insulin resistance, and hyperandrogenemia are commonly seen in women with polycystic ovary syndrome (PCOS), and these three conditions form a vicious cycle leading to reproductive and metabolic abnormalities. Metformin improves the symptoms of PCOS by increasing insulin sensitivity but is not therapeutically optimal. Recent studies have reported that sodium-glucose co-transporter protein receptor inhibitors improve insulin resistance and reduce the weight of patients with PCOS. We performed a meta-analysis to assess the influence of sodium-glucose co-transporter protein-2 (SGLT2) inhibitors on anthropometric, glycolipid metabolism and reproductive outcomes after therapy of overweight/obese women with PCOS. METHODS We searched the relevant literature published up to April 2023. Information on the effect of SGLT2 inhibitors on overweight/obese patients with PCOS was extracted independently by two reviewers. Review Manager 5.3 was used for meta-analysis. RESULTS Five randomized controlled trials that met our criteria were retrieved. Our meta-analysis demonstrated that in overweight/obese patients with PCOS, SGLT2 inhibitors treatment was significantly superior to metformin treatment in terms of reducing body weight (P = 0.02, I2 = 36%), decreasing dehydroepiandrosterone sulfate concentrations [SMD = -0.42, 95% CI (-0.76, -0.07), I2 = 22%, P = 0.02], and reducing the incidence of nausea [RR = 0.35, 95% CI (0.21, 0.60), I2 = 71%, P = 0.0001]. CONCLUSIONS SGLT2 inhibitors are a possible alternative therapy for treating overweight/obese women with PCOS who do not respond favorably to metformin treatment. However, further large randomized controlled trials and cost-effectiveness analyses are warranted to guide the implementation of SGLT2 inhibitors treatment in this population.

Abstract
Endometriosis and polycystic ovary syndrome (PCOS) are two common female reproductive disorders with a significant impact on the health and quality of life of women affected. A novel hypothesis by evolutionary biologists suggested that these two diseases are inversely related to one another, representing a pair of diametrical diseases in terms of opposite alterations in reproductive physiological processes but also contrasting phenotypic traits. However, to fully explain the phenotypic features observed in women with these conditions, we need to establish a potential nexus system between the reproductive system and general biological functions. The recent discovery of kisspeptin as pivotal mediator of internal and external inputs on the hypothalamic-pituitary-gonadal axis has led to a new understanding of the neuroendocrine upstream regulation of the human reproductive system. In this review, we summarize the current knowledge on the physiological roles of kisspeptin in human reproduction, as well as its involvement in complex biological functions such as metabolism, inflammation and pain sensitivity. Importantly, these functions are known to be dysregulated in both PCOS and endometriosis. Within the evolving scientific field of "kisspeptinology", we critically discuss the clinical relevance of these discoveries and their potential translational applications in endometriosis and PCOS. By exploring the possibilities of manipulating this complex signaling system, we aim to pave the way for novel targeted therapies in these reproductive diseases.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine condition in premenopausal women and is a common cause of anovulatory subfertility. Although obesity does not form part of the diagnostic criteria, it affects a significant proportion of women with PCOS and is strongly implicated in the pathophysiology of the disease. Both PCOS and obesity are known to impact fertility in women; obesity also reduces the success of assisted reproductive technology (ART). With or without pharmacotherapy, lifestyle intervention remains the first-line treatment in women with PCOS and obesity. Bariatric surgery is still an experimental treatment in women with PCOS and subfertility. This review will present an overview of the pathophysiology of PCOS and obesity and the role of bariatric surgery. Although data are sparse regarding the impact of bariatric surgery on subfertility in women with PCOS and obesity, existing studies point to a beneficial role in treating metabolic and reproductive dysfunction.

Abstract
Polycystic ovary syndrome is characterised by excessive levels of androgens and ovulatory dysfunction, and is a common endocrine disorder in women of reproductive age. Polycystic ovary syndrome arises as a result of polygenic susceptibility in combination with environmental influences that might include epigenetic alterations and in utero programming. In addition to the well recognised clinical manifestations of hyperandrogenism and ovulatory dysfunction, women with polycystic ovary syndrome have an increased risk of adverse mental health outcomes, pregnancy complications, and cardiometabolic disease. Unlicensed treatments have limited efficacy, mostly because drug development has been hampered by an incomplete understanding of the underlying pathophysiological processes. Advances in genetics, metabolomics, and adipocyte biology have improved our understanding of key changes in neuroendocrine, enteroendocrine, and steroidogenic pathways, including increased gonadotrophin releasing hormone pulsatility, androgen excess, insulin resistance, and changes in the gut microbiome. Many patients with polycystic ovary syndrome have high levels of 11-oxygenated androgens, with high androgenic potency, that might mediate metabolic risk. These advances have prompted the development of new treatments, including those that target the neurokinin-kisspeptin axis upstream of gonadotrophin releasing hormone, with the potential to lessen adverse clinical sequelae and improve patient outcomes.

Abstract
Polycystic ovary syndrome (PCOS) is a complex, but relatively common endocrine disorder associated with chronic anovulation, hyperandrogenism, and micro-polycystic ovaries. In addition to reduced fertility, people with PCOS have a higher risk of obesity, insulin resistance, and metabolic disease, all comorbidities that are associated with mitochondrial dysfunction. This review summarizes human and animal data that report mitochondrial dysfunction and metabolic dysregulation in PCOS to better understand how mitochondria impact reproductive organ pathophysiology. This in-depth review considers all the elements regulating mitochondrial quantity and quality, from mitochondrial biogenesis under the transcriptional regulation of both the nuclear and mitochondrial genome to the ultrastructural and functional complexes that regulate cellular metabolism and reactive oxygen species production, as well as the dynamics that regulate subcellular interactions that are key to mitochondrial quality control. When any of these mitochondrial functions are disrupted, the energetic equilibrium within the cell changes, cell processes can fail, and cell death can occur. If this process is ongoing, it affects tissue and organ function, causing disease. The objective of this review is to consolidate and classify a broad number of PCOS studies to understand how various mitochondrial processes impact reproductive organs, including the ovary (oocytes and granulosa cells), uterus, placenta, and circulation, causing reproductive pathophysiology. A secondary objective is to uncover the potential role of mitochondria in the transgenerational transmission of PCOS and metabolic disorders.

Abstract
PURPOSE Despite the introduction of various pharmaceutical therapies for treating obesity, selecting the optimal treatment remains challenging for both patients and physicians. Therefore, in this network meta-analysis (NMA), we aim to simultaneously compare the available drugs for treating obesity to determine the most effective treatment options. METHODS International databases, including PubMed, Web of Science, Scopus, Cochrane Library, and Embase, were searched for studies published from database inception to April 2023. The consistency assumption was evaluated using by the loop-specific and design × treatment interaction approaches. The effects of treatment in the NMA were summarized using mean differences based on a change score analysis. The random-effects model was used to report the results. Results were reported with 95% CIs. FINDINGS Of 9519 retrieved references, 96 randomized controlled trials, including 68 with both men and women, 23 with women only, and 5 with men only, met the eligibility criteria for this study. There were 4 treatment networks in the trials of both men and women, 4 in the trials of women only, and 1 in the trials of men only. The best-ranked treatments in the network in the trials of both men and women were (1) semaglutide, 2.4 mg (P-score = 0.99); (2) hydroxycitric acid, 4667 mg 3 times daily, supervised walking, and 2000-kcal/d diet (P-score = 0.92); (3) phentermine hydrochloride and behavioral therapy (P-score = 0.92); and (4) liraglutide plus advice to diet and exercise (P-score = 1.00). In women, the best-ranked treatments were beloranib (P-score = 0.98) and sibutramine, metformin, and hypocaloric diet (P-score = 0.90). In men, there was no significant difference among treatments. IMPLICATIONS According to the results of this NMA, semaglutide seems to be an effective treatment option for both men and women, whereas beloranib appears to be particularly effective for women with obesity and overweight, but its production has been stopped since 2016 and is not available.

Abstract
OBJECTIVE To focus on the intersection of perception, diagnosis, stigma, and weight bias in the management of obesity and obtain consensus on actionable steps to improve care provided for persons with obesity. METHODS The American Association of Clinical Endocrinology (AACE) convened a consensus conference of interdisciplinary health care professionals to discuss the interplay between the diagnosis of obesity using adiposity-based chronic disease (ABCD) nomenclature and staging, weight stigma, and internalized weight bias (IWB) with development of actionable guidance to aid clinicians in mitigating IWB and stigma in that context. RESULTS The following affirmed and emergent concepts were proposed: (1) obesity is ABCD, and these terms can be used in differing ways to communicate; (2) classification categories of obesity should have improved nomenclature across the spectrum of body mass index (BMI) using ethnic-specific BMI ranges and waist circumference (WC); (3) staging the clinical severity of obesity based on the presence and severity of ABCD complications may reduce weight-centric contribution to weight stigma and IWB; (4) weight stigma and internalized bias are both drivers and complications of ABCD and can impair quality of life, predispose to psychological disorders, and compromise the effectiveness of therapeutic interventions; (5) the presence and of stigmatization and IWB should be assessed in all patients and be incorporated into the staging of ABCD severity; and (6) optimal care will necessitate increased awareness and the development of educational and interventional tools for health care professionals that address IWB and stigma. CONCLUSIONS The consensus panel has proposed an approach for integrating bias and stigmatization, psychological health, and social determinants of health in a staging system for ABCD severity as an aid to patient management. To effectively address stigma and IWB within a chronic care model for patients with obesity, there is a need for health care systems that are prepared to provide evidence-based, person-centered treatments; patients who understand that obesity is a chronic disease and are empowered to seek care and participate in behavioral therapy; and societies that promote policies and infrastructure for bias-free compassionate care, access to evidence-based interventions, and disease prevention.

Pioglitazone can improve liver sex hormone-binding globulin levels and lipid metabolism in polycystic ovary syndrome by regulating hepatocyte nuclear factor-4α. J Steroid Biochem Mol Biol 2023; 229:106265.

Abstract
Polycystic ovary syndrome (PCOS) is a common reproductive and metabolic disorder that is closely correlated with insulin resistance. Sex hormone-binding globulin (SHBG) is an important carrier for regulating androgen activity and is affected by insulin level, which is related to metabolic abnormalities and long-term prognosis of PCOS. Insulin sensitizer pioglitazone can improve the SHBG level and dyslipidaemia in PCOS, but the mechanism remains unclear. We investigated liver SHBG expression, liver lipid levels, and the effects and potential mechanisms of pioglitazone on reproductive and metabolic disorders in a rat model of polycystic ovary syndrome with insulin resistance (PCOS-IR). PCOS-IR was induced by letrozole and a high-fat diet. Metformin was used as a positive control. Additionally, dihydrotestosterone and oleic acid combined with palmitic acid were used to induce the HepG2 cell models with IR. The cells were exposed to pioglitazone alone or in combination with a hepatocyte nuclear factor (HNF)- 4α inhibitor. Changes in biochemical characteristics were analysed using an enzyme-linked immunosorbent assay. Vaginal smears were used to analyse the oestrous cycle, and ovarian histology was used to analyse the changes in ovarian morphology. The degree of IR in vivo and in vitro was measured using the hyperinsulinaemic-euglycaemic clamp and glucose oxidase techniques. The levels of key anabolism-related proteins, including SHBG, HNF-4α, and peroxidase proliferator-activated receptor (PPAR-γ), were measured using western blots. Pioglitazone and metformin significantly increased the SHBG levels in the sera and livers. Compared to metformin, pioglitazone significantly improved the lipid droplet deposition, triglyceride (TG) and total cholesterol (TC) levels, HNF-4α protein expression, and weights of the livers in the PCOS-IR rats. After applying pioglitazone with an HNF-4α inhibitor in the PCOS-IR cell models, we found that pioglitazone may increase SHBG and improve IR, TG, and TC levels by upregulating HNF-4α. Similar to metformin, pioglitazone also restored the oestrous cycle and ovarian morphology, ameliorated IR and hyperandrogenaemia in the PCOS-IR rats. Our findings hint at the value of HNF-4α in the treatment of PCOS by PIO, which could shed light on potential targets that may be used in treatments for PCOS with metabolic disorders.

Abstract
Polycystic ovary syndrome (PCOS) is a common hormonal condition with reproductive, metabolic, and psychological sequelae that affects 8 to 13% of reproductive-aged women and 3 to 11% of adolescent girls. Sleep is often compromised in women with PCOS due to increased rates of sleep problems, with the most established problem being obstructive sleep apnea (OSA). OSA is highly prevalent in reproductive-aged adult women with PCOS, but not so in adolescence. The international evidence-based PCOS guideline to improve health outcomes in women with PCOS indicated routine screening to identify and alleviate symptoms of OSA. The guidelines, however, did not weigh other multidimensional constructs of sleep health such as sleep disturbances (e.g., sleep quality and quantity), beyond OSA. This is perhaps due to the lack of research and existing mixed findings in the area of PCOS and sleep health. This narrative review summarizes the current knowledge about OSA and expands further to include the limited knowledge about other sleep problems in PCOS among reproductive-aged women and adolescent girls. We broadly cover the prevalence, risk factors, and mechanisms of sleep problems in PCOS and their relationship with cardiometabolic and psychological health. A brief summary on treatment and intervention strategies for sleep problems in PCOS and future recommendations will be deliberated.

Abstract
Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine disorder in women of reproductive age. It presents with gynaecologic, metabolic, and psychologic manifestations. The dominant drivers of pathophysiology are hyperandrogenism and insulin resistance. Both conditions are related to cardiometabolic risk factors, such as obesity, hypertension, dyslipidaemia, hyperglycaemia, type 2 and gestational diabetes, nonalcoholic fatty liver disease and obstructive sleep apnoea. Women with PCOS of reproductive age consistently demonstrated an elevated risk of subclinical atherosclerosis, as indicated by different measurement methods, while findings for menopausal age groups exhibited mixed results. Translation of subclinical atherosclerosis into the increased incidence of peripheral arterial disease and major cardiovascular (CV) events is less clear. Although several expert groups have advised screening, the CV risk assessment and prevention of CV events are frequently underdiagnosed and overlooked aspects of the management of PCOS. A combination of lifestyle management and pharmacotherapy, including the promising new era of anti-obesity medicine, can lead to improvements in cardiometabolic health.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a common hormonal, metabolic, and reproductive disorder with a heterogeneous phenotype. As the exact etiology of PCOS is still unclear, available pharmacotherapies are mostly directed toward alleviating symptoms and associated metabolic abnormalities. AREAS COVERED Herein, we present an overview of the current and emerging pharmacotherapies for the management of women with PCOS who do not seek pregnancy. We performed a literature search in PubMed database up to January 2022 and reviewed papers assessing drug treatments for PCOS. We aimed to outline the most recent evidence to support treatment recommendations in these patients. EXPERT OPINION Targets for medical treatment include hormonal, reproductive, and metabolic abnormalities in PCOS. However, none of the available pharmacological options can cover the entire spectrum of clinical manifestations observed in these patients. Considering the heterogeneity of PCOS, treatment should be individualized and adapted to specific needs of each patient. Better understanding of the molecular mechanisms underlying the pathogenesis of PCOS would help development of novel, safer, and more effective multi-targeted therapeutic strategies for the syndrome.

Abstract
Maternal high-fat (HF) diet exposure in utero may affect fetal development and cause metabolic problems throughout life due to lipid dysmetabolism and oxidative damage. Metformin has been suggested as a potential treatment for body weight reduction and nonalcoholic fatty liver disease, but its reprogramming effect on offspring is undetermined. This study assesses the effects of maternal metformin treatment on hepatic steatosis in offspring caused by maternal HF diet. Female rats were fed either a control or an HF diet before conception, with or without metformin treatment during gestation, and placenta and fetal liver tissues were collected. In another experiment, the offspring were fed a control diet until 120 d (adult stage). Metformin treatment during pregnancy ameliorates placental oxidative stress and enhances placental glucose transporter 1 (GLUT1), GLUT3, and GLUT4 expression levels through 5' adenosine monophosphate-activated protein kinase (AMPK) activation. Maternal metformin treatment was shown to reprogram maternal HF diet-induced changes in offspring fatty liver with the effects observed in adulthood as well. Further validation is required to develop maternal metformin therapy for clinical applications.

[PMID: 36276397 PMCID: PMC9581187 DOI: 10.3389/fpubh.2022.962083] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Accepted: 09/06/2022] [Indexed: 01/24/2023] Open
Abstract
Objective Weight issues, dysmorphic concerns and eating disorders are common among individuals with polycystic ovary syndrome (PCOS) and are linked to poor quality of life (QoL). The goal of the current study was to examine whether the association between body mass index (BMI) and QoL was mediated by dysmorphic concerns, examining also the relations with eating disorder symptomatology. Methods Questionnaires were administered to 435 individuals with PCOS aged between 18 and 40 years (M = 27.62; SD = 4.83) to measure dysmorphic concerns, eating disorder symptoms and QoL. Participants were also asked to report their height and weight to compute their BMI. Results Structural equation modeling was used to observe the relationship between the variables. The results revealed a direct relationship between QoL, BMI, dysmorphic concerns and eating disorder symptomatology. In addition, dysmorphic concerns were related to BMI and eating disorder symptomatology. Furthermore, the results showed the mediating role of dysmorphic concerns and eating disorder symptoms in the relationship between BMI and QoL. Conclusion The current results highlight the potential importance of harmful relationships with one's own body and food, explaining why weight issues may be linked to different levels of QoL in PCOS individuals. The implications of these findings are discussed.

Abstract
Despite the continuous effort to understand the pathophysiology and determine potential therapeutic targets, PCOS treatment largely depends on lifestyle intervention and symptomatic management of individual signs and symptoms. International guidelines recognize the importance of weight reduction as a cornerstone for the achievement of better metabolic, reproductive, and cardiovascular outcomes in PCOS women who are overweight or obese. With its profound weight loss potential in patients with or without diabetes, the administration of GLP-1 receptor agonists has been investigated in overweight/obese women with PCOS in several single-center randomized control trials with considerable variation in the dosing regimen, follow-up duration, and outcome measurements over recent years. Most trials reported superior weight loss effects of GLP-1 receptor agonists compared to lifestyle changes or metformin, with additional metabolic, reproductive, and cardiovascular benefits in this population. However, their use is currently not widely accepted by the clinical community that treats this population. The major concern is how to balance the reproductive and metabolic treatment strategies since the use of GLP-1 receptor agonists requires effective contraception while on therapy and a washout period before pregnancy. Both approaches are not mutually exclusive, yet the best choice requires a careful assessment of the clinical context. Knowing a patient's individual circumstances, precise clinical sub-phenotyping, and regular monitoring are crucial components for the safe and effective use of these new tools. In the present narrative review, we explore the current clinical evidence and provide the future perspectives and challenges for their implementation in PCOS management.

Abstract
PURPOSE The majority of Polycystic ovary syndrome (PCOS) are overweight or obese with increased infertility and high risk of pregnancy complications. We aim to compare efficacy of metformin and exenatide on spontaneous pregnancy rate, overall pregnancy rate after assisted reproductive technology treatment (ART) and pregnancy outcomes in overweight or obese infertility PCOS. METHODS In this long-term follow-up study, 160 overweight or obese infertility Chinese PCOS were randomized to exenatide or metformin treatment for 12 weeks. Afterward, all were treated with metformin alone until pregnancy confirmed and followed until delivery. If patients failed spontaneous pregnancy during the second 12 weeks, ART could be offered until end of 64 weeks. The primary outcome was spontaneous pregnancy rate. RESULTS At week 24, 29.2% of women in exenatide group conceived spontaneously while 14.7% in metformin group (p = 0.03). At week 64, total pregnancy rates were 79.2% in exenatide group and 76% in metformin group without significant difference (p = 0.65). Between two groups, there was no significant difference of pregnancy outcomes (p > 0.05). A stepwise logistic regression showed that spontaneous pregnancy was positively associated with body weight reduction and HOMA-IR improvement in either group. CONCLUSION In overweight or obese infertility Chinese PCOS, 12 weeks pregestational exenatide treatment resulted in more spontaneous pregnancy likely due to greater weight reduction and improvement of insulin resistance compared with metformin treatment without obvious benefit on overall pregnancy rate after ART or pregnancy outcomes of successful conceived women. TRIAL REGISTRATION This clinical trial was registered at Chinese Clinical Trials Registry (ChiCTR-IIR-16008084) on 13/3/2016.

Prospective Risk of Type 2 Diabetes in Normal Weight Women with Polycystic Ovary Syndrome. Biomedicines 2022; 10:biomedicines10061455. [PMID: 35740476 PMCID: PMC9220967 DOI: 10.3390/biomedicines10061455] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 06/09/2022] [Accepted: 06/17/2022] [Indexed: 12/31/2022] Open
Abstract
Background: Polycystic ovary syndrome (PCOS) is associated with obesity and increased risk for type 2 diabetes (T2D). However, the prospective risk of T2D in normal weight women with PCOS is debated, together with the relevant prospective screening programs for T2D in normal weight women with PCOS. Aim: To review and discuss prospective risk of T2D in normal weight women with PCOS, and to give recommendations regarding prospective screening for T2D in normal weight women with PCOS. Methods: Systematic review. Results: A systematic literature search resulted in 15 published prospective studies (10 controlled studies and 5 uncontrolled studies) regarding risk of T2D in study cohorts of PCOS, where data from normal weight women with PCOS were presented separately. In controlled studies, higher risk of T2D in normal weight women with PCOS compared to controls was reported in 4/10 studies, which included one study where T2D diagnosis was based on glucose measurement, two register-based studies, and one study where diagnosis of T2D was self-reported. Six of the 10 controlled studies reported no increased risk of T2D in normal weight women with PCOS. Four of these studies based the diagnosis of T2D on biochemical measurements, which supported the risk of surveillance bias in PCOS. In uncontrolled studies, 2/5 reported a higher risk of T2D in lean women with PCOS compared to the general population. We discuss the evidence for insulin resistance and β-cell dysfunction in normal weight women with PCOS, and aggravation in the hyperandrogenic phenotype, ageing women, and women with Asian ethnicity. Impaired glucose tolerance could be an important metabolic and vascular risk marker in PCOS. Conclusions: The risk of T2D may be increased in some normal weight women with PCOS. Individual risk markers such as hyperandrogenism, age >40 years, Asian ethnicity, and weight gain should determine prospective screening programs in normal weight women with PCOS.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a heterogeneous reproductive endocrine disorder. Several ongoing trials test sodium-glucose cotransporter-2 (SGLT-2) inhibitors for women with PCOS. However, their effectiveness has not been fully elucidated owing to the lack of high-confidence evidence. Our group agrees with the statement that SGLT-2 inhibition could treat PCOS as it is supported by reports demonstrating the benefits of SGLT-2 inhibition on metabolic status and weight control. Moreover, the functions of chronic inflammation amelioration and cardiovascular system protection make it a more attractive candidate for PCOS therapy. Therefore, to provide physicians with a reference, we intend to perform a meta-analysis on the efficacy and safety of SGLT-2 inhibitors on the endocrine and metabolic profiles of patients with PCOS. METHODS AND ANALYSIS We will search for randomised controlled trials performed until September 2022 using PubMed, Web of Science, EMBASE, the Cochrane Library, Google Scholar, the PhRMA Clinical Study Results Database (www. CLINICALTRIALS gov), the China National Knowledge Infrastructure, the Wanfang, the Weipu and the Chinese biomedical literature databases. The outcomes will include androgen-associated outcomes, body fat, glucose and lipid homoeostasis, inflammatory outcomes and adverse events. In addition, two investigators will independently assess methodological quality using the revised Cochrane risk-of-bias tool 2. The analysis will be performed using RevMan V.5.3 software, and subgroup and sensitivity analyses and a meta-regression will be used to determine the heterogeneity source. ETHICS AND DISSEMINATION Ethical approval is not required because this is a meta-analysis. We will disseminate these results by publishing them in a peer-reviewed journal.

Abstract
Metformin is a glucose-lowering drug commonly found in municipal wastewater effluents (MWWEs). The present study investigated the chronic effects of metformin in early-life stages of the fathead minnow (Pimephales promelas). Endpoints assessed were growth, survival, and deformities. The larval gut microbiome was also examined using 16 S ribosomal RNA gene amplicon sequencing to determine microbial community composition and alpha and beta diversity. Eggs and larvae were exposed to metformin measured concentrations (mean [standard deviation]) of 0.020 (0.017) μg/L (for controls) and 3.44 (0.23), 33.6 (1.6), and 269 (11) μg/L in a daily static-renewal setup, with 20 embryos per beaker. The low and middle metformin exposure concentrations represent river and MWWE concentrations of metformin. To detect small changes in growth, we used 18 replicate beakers for controls and 9 replicates for each metformin treatment. Over the 21-d exposure (5 d as embryos and 16 d posthatch [dph]), metformin did not affect survival or growth of larval fish. Hatch success, time to hatch, deformities in hatched fry, and survival were similar across all treatments. Growth (wet wt, length, and condition factor) assessed at 9 and 16 dph was also unaffected by metformin. Assessment of the microbiome showed that the larvae microbiome was dominant in Proteobacteria and Firmicutes, with small increases in Proteobacteria and decreases in Firmicutes with increasing exposure to metformin. No treatment effects were found for microbiome diversity measures. Control fish euthanized with the anesthetic tricaine methane sulfonate had decreased alpha diversity compared to those sampled by spinal severance. This experiment demonstrates that metformin at environmentally relevant concentrations (3.44 and 33.6 μg/L) and at 10 times MWWE concentrations (269 µg/L) does not adversely affect larval growth or gut microbiome in this ubiquitous freshwater fish species.

Abstract
PURPOSE The purpose of this study is to evaluate the effectiveness and safety of liraglutide/liraglutide + metformin in overweight/obese women with polycystic ovary syndrome (PCOS). METHODS The related literatures published until April 2021 were searched in PubMed, Cochrane Library, MEDLINE and EmBase. RESULTS Six randomized controlled trials of 127 related articles were obtained through searching. Three articles compared liraglutide with metformin, and four articles compared liraglutide combined with metformin with metformin. Our meta-analysis suggests that liraglutide was superior to metformin only in weight loss [MD = - 2.74, 95% CI (- 4.29, - 1.18), P = 0.0006]. Compared with metformin group, the combination group had significant advantages in weight loss [MD = - 3.81, 95% CI (- 5.16, - 2.46), P < 0.001], BMI [MD = - 2.59, 95% CI (- 3.12, - 2.07), P < 0.001], waist circumference [MD = - 6.26, 95% CI (- 7.79, - 4.72), P < 0.001], fasting blood glucose [MD = - 0.59, 95% CI (- 0.74, - 0.44), P < 0.001] and fasting insulin [MD = - 1.52, 95% CI (- 2.69, - 0.35), P = 0.01], while the incidence of adverse reactions was relatively high [RR = 2.91, 95% CI (1.55, 5.46), P = 0.00009]. CONCLUSION The present results indicate that liraglutide and metformin have the similar effects in the treatment of overweight/obese PCOS patients. Liraglutide combined with metformin is more effective than metformin in improving PCOS, but it is necessary to master the correct medication method to reduce the occurrence of adverse reactions.

Abstract
OBJECTIVES Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathy disorders in premenopausal women, which is characterized by hyperandrogenemia, anovulation, and polycystic ovarian morphology (PCOM). Time-restricted feeding (TRF) is a new intermittent restriction dietary pattern, which has been shown to have positive benefits on obesity and glycolipid metabolism disorders. We aimed to explore the effect of the feeding regimen (ad libitum vs. TRF) on the glycolipid metabolism and reproductive endocrine disorders in a PCOS mouse model. METHODS PCOS mouse model was induced by continuous subcutaneous administration of dihydrotestosterone for 21 days. Mice were fed a high-fat diet (HFD) for 8 weeks on an ad libitum or time- restricted diet (from 10:30 p.m. to 6:30 a.m.). RESULTS Compared to control mice, PCOS mice that received TRF treatment had significantly lower body weight, reduced adiposity, lower area under the curve (AUC) of glucose response in the oral glucose tolerance test (OGTT), and lower AUC in the insulin tolerance test (ITT). TRF also ameliorated lipid metabolism, as shown by a reduction in plasma lipid profiles (triglycerides and cholesterol) and the triglyceride content in the liver of PCOS mice. In terms of reproduction, the plasma androgen level, plasma estrogen (E2) level, and luteinizing hormone (LH)/follicle stimulating hormone (FSH) ratio in PCOS mice were significantly reduced after 8 weeks of TRF treatment. In addition, ovarian histology showed that TRF inhibits cyst formation and promotes corpus luteum formation. CONCLUSION In conclusion, TRF improved metabolic and endocrine profiles in mice with PCOS.

Front Endocrinol (Lausanne) 2022; 13:1051111. [PMID: 36387924 PMCID: PMC9646792 DOI: 10.3389/fendo.2022.1051111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 10/12/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a multi-factorial heterogeneous syndrome that has both adverse reproductive and metabolic implications for affected women and its management is a challenging clinical problem. Curcumin, as a phenolic compound with potent anti-inflammatory and antioxidant properties exerting positive effects on the lipid profile and insulin resistance, appears to be a valuable treatment regimen for patients with PCOS. OBJECTIVE This study aimed to evaluate the efficacy and safety of curcumin in the treatment of PCOS. METHODS Chinese databases (Chinese National Knowledge Infrastructure, China Biology Medicine Databases, VIP database, Wanfang Database, and Chinese Clinical Trial Registry) and English databases (PubMed, Web of Science, Embase, Cochrane Library, Scopus and Clinical trials) were thoroughly investigated through screening randomized controlled trials on curcumin in PCOS published from the date of inception to May 2022. Standardized data search and abstraction were conducted following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. Quantitative and qualitative analyses were performed. Heterogeneity was assessed using I2 statistics. RESULTS A total of 447 patients from seven randomized controlled trials were included in the meta-analysis. Results showed that the ingestion of curcumin decreased body mass index (WMD -0.267, 95% CI -0.450 to -0.084, P = 0.004, I2 = 0.0%), fasting plasma glucose (WMD -3.618, 95% CI -5.165 to -2.071, P < 0.001, I2 = 20.4%), insulin (WMD -1.834, 95% CI -2.701 to -0.968, P < 0.001, I2 = 8.4%), homeostatic model assessment for insulin resistance (WMD -0.565, 95% CI -0.779 to -0.351, P < 0.001, I2 = 0.0%), total cholesterol (WMD -15.591, 95% CI -27.908 to -3.273, P = 0.013, I2 = 68.9%), C-reactive protein (WMD -0.785, 95% CI -1.553 to -0.017, P = 0.045, I2 = 23.9%), and increased the quantitative insulin sensitivity check index (WMD 0.011, 95% CI 0.005 to 0.017, P = 0.001, I2 = 39.6%). As for safety, the treatment group did not cause significant adverse reactions than that in the control group. CONCLUSION In light of presented findings, curcumin has beneficial effects on serum markers of inflammation, weight loss and glucose and lipid metabolism in patients with PCOS. The incidence of adverse reactions does not increase with the application of curcumin. However, a larger, more definitive study is needed to further investigate these results.

Abstract
Increased insulin is associated with obesity-related airway hyperreactivity and asthma. We tested whether the use of metformin, an antidiabetic drug used to reduce insulin resistance, can reduce circulating insulin, thereby preventing airway hyperreactivity in rats with dietary obesity. Male and female rats were fed a high- or low-fat diet for 5 wk. Some male rats were simultaneously treated with metformin (100 mg/kg orally). In separate experiments, after 5 wk of a high-fat diet, some rats were switched to a low-fat diet, whereas others continued a high-fat diet for an additional 5 wk. Bronchoconstriction and bradycardia in response to bilateral electrical vagus nerve stimulation or to inhaled methacholine were measured in anesthetized and vagotomized rats. Body weight, body fat, caloric intake, fasting glucose, and insulin were measured. Vagally induced bronchoconstriction was potentiated only in male rats on a high-fat diet. Males gained more body weight, body fat, and had increased levels of fasting insulin compared with females. Metformin prevented development of vagally induced airway hyperreactivity in male rats on high-fat diet, in addition to inhibiting weight gain, fat gain, and increased insulin. In contrast, switching rats to a low-fat diet for 5 wk reduced body weight and body fat, but it did not reverse fasting glucose, fasting insulin, or potentiation of vagally induced airway hyperreactivity. These data suggest that medications that target insulin may be effective treatment for obesity-related asthma.

Abstract
Polycystic ovary syndrome (PCOS) is a chronic multisystem endocrine disorder that affects women of reproductive age. In the ovary, the dynamic balance between dormant and growing follicles that culminates in ovulation becomes dysfunctional in the presence of excessive androgen production (ovarian/adrenal/peripheral). Moreover, hyperandrogenicity in pregnancy affects fetal development in utero and is linked to maternal pregnancy complications. Hormonal imbalance, ovarian dysfunction, and central obesity often emerge in these patients during adolescence. Once disordered physiological changes develop in PCOS, a vicious cycle ensues, leading to reproductive, metabolic, and psychological comorbidities. With the alarming increase of the number of young adults with a high degree of obesity in Korea, the prevalence of PCOS has also considerably increased. Timely and accurate screening, multicomponent healthy lifestyle modifications for both patients and family members, and comprehensive medical interventions based on international evidence-based guidelines are essential for curtailing PCOS and its comorbidities.

Abstract
OBJECTIVE To analyse the comparative effectiveness of different health wearable-based physical activity (PA) promotion intervention strategies against each other and control for reducing body weight and body mass index (BMI) in individuals with overweight/obesity and chronic comorbidities. DESIGN Systematic review and network meta-analysis (PROSPERO identifier: CRD42020158191). DATA SOURCES We performed two independent searches from December 2019 to September 2020 in PubMed, MEDLINE, Scopus, Web of Science, Central Register of Controlled Trials, EMBASE and PsycINFO databases for articles published in English between 2007 and 2020. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Inclusion criteria were based on the PICOS framework. We included randomised controlled trials of health wearable-based interventions using two or more PA intervention arms/strategies and compared their effects on participants' body weight (kg) and BMI (kg/m2) with a control group. Data were analysed using a Bayesian network meta-analysis to directly and indirectly compare the effects of the six different intervention strategies (comparators). The six comparators were: (1) control group (ie, usual care, waitlist); (2) comparison group (ie, traditional, non-health wearable PA interventions); (3) commercial health wearable-only intervention (eg, Fitbit, Polar M400); (4) research grade health wearable-only intervention (ie, accelerometers or pedometers); (5) multicomponent commercial health wearable intervention (eg, Fitbit + nutrition counselling); and (6) multicomponent research grade health wearable intervention. The results were reported as standardised mean differences (SMDs) with associated 95% credible intervals (CrIs). RESULTS From 641 screened records, 31 studies were included. For body weight reduction in individuals with overweight/obesity and chronic comorbidities, accelerometer/pedometer-only (SMD -4.44, 95% CrI -8.94 to 0.07) and commercial health wearable-only (SMD -2.76, 95% CrI -4.80 to -0.81) intervention strategies were the most effective compared with the three other treatments and control. For BMI reduction, multicomponent accelerometer/pedometer (SMD -3.43, 95% CrI -4.94 to -2.09) and commercial health wearable-only (SMD -1.99, 95% CrI -4.95 to 0.96) intervention strategies were the most effective compared with the other four conditions. CONCLUSION Health wearable devices are effective intervention tools/strategies for reducing body weight and BMI in individuals with overweight/obesity and chronic comorbidities.

Abstract
Evolutionary and comparative approaches can yield novel insights into human adaptation and disease. Endometriosis and polycystic ovary syndrome (PCOS) each affect up to 10% of women and significantly reduce the health, fertility, and quality of life of those affected. PCOS and endometriosis have yet to be considered as related to one another, although both conditions involve alterations to prenatal testosterone levels and atypical functioning of the hypothalamic-pituitary-gonadal (HPG) axis. Here, we propose and evaluate the novel hypothesis that endometriosis and PCOS represent extreme and diametric (opposite) outcomes of variation in HPG axis development and activity, with endometriosis mediated in notable part by low prenatal and postnatal testosterone, while PCOS is mediated by high prenatal testosterone. This diametric disorder hypothesis predicts that, for characteristics shaped by the HPG axis, including hormonal profiles, reproductive physiology, life-history traits, and body morphology, women with PCOS and women with endometriosis will manifest opposite phenotypes. To evaluate these predictions, we review and synthesize existing evidence from developmental biology, endocrinology, physiology, life history, and epidemiology. The hypothesis of diametric phenotypes between endometriosis and PCOS is strongly supported across these diverse fields of research. Furthermore, the contrasts between endometriosis and PCOS in humans parallel differences among nonhuman animals in effects of low versus high prenatal testosterone on female reproductive traits. These findings suggest that PCOS and endometriosis represent maladaptive extremes of both female life-history variation and expression of sexually dimorphic female reproductive traits. The diametric disorder hypothesis for endometriosis and PCOS provides novel, unifying, proximate, and evolutionary explanations for endometriosis risk, synthesizes diverse lines of research concerning the two most common female reproductive disorders, and generates future avenues of research for improving the quality of life and health of women.

Abstract
Several pharmacological approaches to controlling body weight have been developed over the last decades, albeit with limited success. Currently available agents include centrally acting appetite suppressants and peripherally acting compounds. Efficacy and safety of these agents in the clinical setting require a difficult balance. Further strategies including multiagonists able to simultaneously target multiple actors involved in obesity initiation and expansion such as the glucagon receptor family are under investigation. The results of recent clinical trials are encouraging and highlight emerging compounds as potential game changers. In view of the rising prevalence of obesity and the associated burden of comorbidities worldwide, and compared with other areas of pharmacological intervention, we feel that the field of obesity has been affected by therapeutic inertia. Of note, obesity may also affect the response to concomitant medications such as low-dose aspirin. Lessons from withdrawn agents such as the cannabinoid receptor antagonist rimonabant include developing compounds with a more targeted action profile (i.e., central vs peripheral, or antagonist versus inverse agonist) as well as careful selection of patients based on individual risk factors. We anticipate that the expanding knowledge base and clinical testing will result in improved outcomes for patients with obesity in the near future.

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.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-aged women. Overweight and obesity commonly accompany the syndrome at the clinic and are significant concerns for women with PCOS. AREAS COVERED Herein, we provide an overview of the relevant literature on weight management strategies in women with PCOS. We performed an electronic-based search using PubMed until February 2021. We aimed to summarize available evidence of different weight-reducing interventions in PCOS and outline the gaps in our current knowledge and recommend areas for further research. EXPERT OPINION PCOS is closely linked to obesity and increased adiposity enhances severity and expression of PCOS phenotype. Current data suggest that weight loss is associated with improved metabolic, endocrine, reproductive, cardiovascular and psychological features in overweight and obese women with PCOS. Lifestyle interventions including diet and exercise, anti-obesity medications and bariatric surgery have been used as therapeutic approaches for short-term management of obesity in PCOS with varying success rates. Large and sufficiently powered studies are required in order to determine long-term effects of weight management strategies and potential benefits beyond weight loss in the syndrome. This would allow informing the guidelines to make PCOS specific evidence-based recommendations.

Abstract
For many patients, weight loss is a first-line measure recommended to reduce comorbidities associated with polycystic ovary disease. When lifestyle modifications such as diet and exercise are insufficient at achieving this goal, the addition of weight loss medications has proven effective for many patients. In patients with severe obesity, bariatric surgery is often used when other methods have been unsuccessful and has shown promising results for improving health and fertility in patients with polycystic ovary disease.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. An endometrial component has been suggested to contribute to subfertility and poor reproductive outcomes in affected women. OBJECTIVE AND RATIONALE The aim of this review was to determine whether there is sufficient evidence to support that endometrial function is altered in women with PCOS, whether clinical features of PCOS affect the endometrium, and whether there are evidence-based interventions to improve endometrial dysfunction in PCOS women. SEARCH METHODS An extensive literature search was performed from 1970 up to July 2020 using PubMed and Web of Science without language restriction. The search included all titles and abstracts assessing a relationship between PCOS and endometrial function, the role played by clinical and biochemical/hormonal factors related to PCOS and endometrial function, and the potential interventions aimed to improve endometrial function in women with PCOS. All published papers were included if considered relevant. Studies having a specific topic/hypothesis regarding endometrial cancer/hyperplasia in women with PCOS were excluded from the analysis. OUTCOMES Experimental and clinical data suggest that the endometrium differs in women with PCOS when compared to healthy controls. Clinical characteristics related to the syndrome, alone and/or in combination, may contribute to dysregulation of endometrial expression of sex hormone receptors and co-receptors, increase endometrial insulin-resistance with impaired glucose transport and utilization, and result in chronic low-grade inflammation, immune dysfunction, altered uterine vascularity, abnormal endometrial gene expression and cellular abnormalities in women with PCOS. Among several interventions to improve endometrial function in women with PCOS, to date, only lifestyle modification, metformin and bariatric surgery have the highest scientific evidence for clinical benefit. WIDER IMPLICATIONS Endometrial dysfunction and abnormal trophoblast invasion and placentation in PCOS women can predispose to miscarriage and pregnancy complications. Thus, patients and their health care providers should advise about these risks. Although currently no intervention can be universally recommended to reverse endometrial dysfunction in PCOS women, lifestyle modifications and metformin may improve underlying endometrial dysfunction and pregnancy outcomes in obese and/or insulin resistant patients. Bariatric surgery has shown its efficacy in severely obese PCOS patients, but a careful evaluation of the benefit/risk ratio is warranted. Large scale randomized controlled clinical trials should address these possibilities.

Abstract
PURPOSE OF REVIEW Effective treatments for pediatric obesity are limited. Glucagon-like peptide-1 receptor (GLP-1R) agonists have emerged as therapeutic agents for obesity in adults and have shown benefits outside of weight loss. Here we explore the evidence for GLP-1R agonist use in pediatric obesity. RECENT FINDINGS Emerging evidence suggests that GLP-1R agonists have a role in pediatric obesity treatment. A recently published, randomized, placebo-controlled trial found a greater reduction in BMI z-score (- 0.22 SDs) in adolescents receiving liraglutide compared with placebo. As in adults, gastrointestinal adverse effects were commonly seen. GLP-1R agonists appear to perform favorably compared with other approved pharmacological agents for pediatric obesity. However, heterogeneity in weight loss response, cost, side effects, and need for injections may limit their use in many pediatric patients. Rather than broadly applying this therapy if it is approved, we suggest careful patient selection and monitoring by clinicians pending further studies.

Abstract
Liraglutide is a long-acting human glucagon-like peptide-1 (GLP-1) analogue and an effective treatment for patients with metabolic diseases including type 2 diabetes mellitus (T2DM) and obesity. This review focuses on the mechanism of action of liraglutide as a well-known glucagon-like peptide-1 receptor agonist (GLP-1 RA) in patients with T2DM and obesity. The lower and the higher doses of GLP-1 RAs are used for glycaemic control in T2DM and in obesity respectively. GLP-1 RAs such as liraglutide enhance insulin secretion and inhibit glucagon release via the stimulation of glucagon-like peptide-1 receptors (GLP-1Rs). Liraglutide decreases hemoglobin A1c (HbA1c) in type 2 diabetes (T2D) patients when prescribes as monotherapy or in combination with one or more antidiabetic drugs. Usually, it is well tolerated with minor hypoglycemia in combination therapy. Liraglutide reduces cardiovascular events and related risk factors including improvement of lipid profile and control of blood pressure. Accordingly, it can be cost-effective and may be a budget neutral medication option by considering its protective effect on the cardiovascular system in long-term use in the health care plan. In the near future, by pharmacogenomics approach, prediction of the highest patient's response with the lowest adverse drug reactions and also rationality of drug development will be possible. Liraglutide can be used as a desirable medicine for glycemic control and obesity. It shows extensive evidence based benefits in diabetes complications. In this narrative review, we have summarized and evaluated studies related to the role of liraglutide in clinical practice.

Abstract
BACKGROUND & AIMS Trials investigating the efficacy of different interventions for overweight children are limited and controversial. Therefore, the aim of this study is to perform a network meta-analysis on the efficacy of various interventions for children with obesity (an average age of 6-12 years old). METHODS We obtained the data of trials reporting pre-post obesity relevant outcomes (e.g. BMI, BMI z-score, percent body fat, or percent overweight) from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), PubMed, and Web of Science databases (completed before February 25, 2019) and included at least one pair of direct comparison groups. The mean difference of outcomes and their associated 95% CI were used to determine the efficacy. The P-score was calculated to illustrate the rank probability of various treatments for different outcomes using a network meta-analysis. Our meta-analysis included 24 studies that evaluated the interventions for childhood obesity. RESULTS All 24 trials had no high risk of bias. Interventions such as exercise without parents (E w/o P); diet with parents (D w/P); and diet, exercise, and lifestyle with parents (D+E+L w/P) were significantly effective for children with obesity when compared with no intervention. CONCLUSIONS E w/o P exhibited the highest P-score, with the D w/P and D+E+L w/P ranks having P-scores of 0.7486 and 0.5464, respectively. Moreover, the results indicate that E w/o P, D w/P, and D+E+L w/P were significantly effective treatments for children with obesity when compared with no intervention.

Abstract
Polycystic ovary syndrome is a complex and heterogenous disorder involving multiple organ systems and different molecular pathways. It is tightly associated with obesity and especially abdominal obesity. As body weight reduction is the main modifiable risk factor for polycystic ovary syndrome, therapeutic approaches in overweight or obese women with polycystic ovary syndrome have been developed. Liraglutide is a glucagon-like peptide-1 receptor agonist that promotes sustained weight loss, as well as abdominal fat reduction, in individuals with obesity, prediabetes, and type 2 diabetes mellitus. The majority of current clinical studies have demonstrated that liraglutide therapy achieved significant reductions in body weight, body mass index, and abdominal circumference in overweight and obese women with polycystic ovary syndrome. Liraglutide therapy promoted significant improvements in free testosterone and sex hormone-binding globulin levels in some studies. Important metabolic and hormonal improvements were also reported after the combination of liraglutide with metformin. Increased menstrual frequency, as well as potential positive effects in reproduction, were described. However, the small number of participants, short duration, and low daily liraglutide dose are some of the main limitations of these studies. Larger and longer, multi-centred, double-blind, placebo-controlled trials of liraglutide monotherapy or combination therapy, with prolonged post-interventional monitoring, are crucially anticipated. Metabolic, hormonal, and reproductive primary outcomes should be uniformly addressed, to tailor future targeted treatment approaches, according to the patient phenotype and needs. This will improve long-term therapeutic outcomes in this population.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17207438. [PMID: 33066039 PMCID: PMC7650570 DOI: 10.3390/ijerph17207438] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 09/27/2020] [Accepted: 10/05/2020] [Indexed: 12/23/2022]
Abstract
Obesity is a well-known risk factor for infertility, and nonpharmacological treatments are recommended as effective and safe, but evidence is still lacking on whether nonpharmacological interventions improve fertility in overweight or obese women. The aim of this study was to systematically assess the current evidence in the literature and to evaluate the impact of nonpharmacological interventions on improving pregnancy-related outcomes in overweight or obese infertile women. Seven databases were searched for randomized controlled trials (RCTs) of nonpharmacological interventions for infertile women with overweight or obesity through August 16, 2019 with no language restriction. A meta-analysis was conducted of the primary outcomes. A total of 21 RCTs were selected and systematically reviewed. Compared to the control group, nonpharmacological interventions significantly increased the pregnancy rate (relative risk (RR), 1.37; 95% CI, 1.04–1.81; p = 0.03; I2 = 58%; nine RCTs) and the natural conception rate (RR, 2.17, 95% CI, 1.41–3.34; p = 0.0004; I2 = 19%, five RCTs). However, they had no significant effect on the live birth rate (RR, 1.36, 95% CI, 0.94–1.95; p=0.10, I2 = 65%, eight RCTs) and increased the risk of miscarriage (RR: 1.57, 95% CI, 1.05–2.36; p = 0.03; I2 = 0%). Therefore, nonpharmacological interventions could have a positive effect on the pregnancy and natural conception rates, whereas it is unclear whether they improve the live birth rate. Further research is needed to demonstrate the integrated effects of nonpharmacological interventions involving psychological outcomes, as well as pregnancy-related outcomes.

Abstract
Gastric inhibitory polypeptide (GIP) is best known as an incretin hormone released by enteroendocrine K-cells in response to feeding and stimulates insulin release to regulate blood glucose and nutrient homeostasis. More recently GIP has been ascribed a positive role in lipid metabolism, bone strength, cardiovascular function and cognition. The present paper considers an emerging role of GIP and related gut hormones in fertility and especially polycystic ovarian syndrome (PCOS). Key evidence concerns restoration of fertility in women with gross obesity and PCOS following bariatric surgery. This is considered to reflect indirect effects mediated by alleviation of insulin resistance together with possible direct effects of surgically induced changes of GIP, GLP-1 and related peptide hormones on ovaries and the hypothalamic-pituitary-adrenal axis. Further studies are required to determine inter-relationships between the hormones and cellular mechanisms involved but these observations suggest that GIP and other gut may provide a novel therapeutic approach for PCOS and other reproductive disorders.

Abstract
Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism and ovulatory dysfunction. Women with PCOS have an elevated prevalence of cardiometabolic risk factors that worsen after menopause. Liraglutide (Lira), a glucagon-like peptide-1 receptor agonist, has shown beneficial metabolic effects in small clinic trials in reproductive-age women with PCOS. We have shown that chronic hyperandrogenemia in an experimental model of postmenopausal PCOS is associated with an adverse cardiometabolic profile and upregulation of the intrarenal renin-angiotensin system (RAS). We analyzed the effect of Lira in the cardiometabolic profile, intrarenal RAS, and blood pressure (BP) in postmenopausal PCOS. Four-week-old female Sprague Dawley rats were treated with DHT or placebo for 17 months. Lira administration during the last 3 weeks caused a bigger reduction in food intake, body weight, fat mass, and homeostasis model assessment of insulin resistance index in PCOS than in control rats. Moreover, Lira improved dyslipidemia and elevated leptin levels in PCOS. In contrast, Lira decreased intrarenal expression of RAS components only in the control group. Lira transiently increased heart rate and decreased BP in control rats. However, Lira did not modify BP but increased heart rate in PCOS. The angiotensin-converting-enzyme inhibitor enalapril abolished the BP differences between PCOS and control rats. However, Lira coadministration with enalapril further reduced BP only in control rats. In summary, Lira has beneficial effects for several cardiometabolic risk factors in postmenopausal PCOS. However, hyperandrogenemia blunted the BP-lowering effect of Lira in postmenopausal PCOS. Androgen-induced activation of intrarenal RAS may play a major role mediating increases in BP in postmenopausal PCOS.

Abstract
Obesity is a disease of high prevalence in Primary Care clinics. It is associated with major comorbidities (dyslipidaemia, diabetes, hypertension) that increase morbidity and mortality, health expenditure, and reduces the quality of life of patients. Changes in lifestyle are still the pillars of the treatment of excess weight. Pharmacological treatment should be considered when there are difficulties in achieving weight loss goals. In this article, a review is presented on the currently authorised drugs for the treatment of obesity and overweight with major comorbidities.

Abstract
It's widely acknowledged that, as a neurodegenerative aging disease representing an intermediate stage between cognitive intactness and Alzheimer's disease (AD), Mild cognitive impairment (MCI) poses an excessive burden on patients' well-being, family members, health-care providers as well as the whole society. This study focuses on three cognitive interventions proposed by Clare and Woods, which are, Cognitive stimulation (CS), Cognitive training (CT) and Cognitive rehabilitation (CR). Our Network meta-analysis (NMA) aims to compar them with one another to determine the optimal cognitive intervention for elderly adults with MCI in improving their cognitive function. We applied extensive strategies to preliminary literature retrieval to identify relevant randomized controlled trials (RCTs) which scrupulously compared any two of the three cognitive interventions with one another or any one of the three with a control group as the placebo or non-active group in treating elder patients with MCI in accordance with Petersen's criteria. Our NMA of cognitive interventions for patients diagnosed with MCI appraised the relative effectiveness of cognitive interventions across trials simultaneously. Our study attempts to summarize available data to suggest that CS (Mean difference [MD] = 0.95, 95% confidence interval [CI]:0.27, 1.70) and CT (MD = 0.70, [CI]:0.11,1.30) were significantly beneficial to MCI patients for improving their cognition status while CR (MD = 0.59, [CI]:-0.30,1.50) scored lowest. Our study suggested CS was most likely to be the best intervention for improving the cognitive function of MCI patients.

Abstract
This meta-analysis aimed to evaluate the efficacy and safety of glucagon-like peptide 1 (GLP-1) receptor agonists for women with polycystic ovary syndrome (PCOS) by comparing their effect with that of metformin. Electronic databases (PubMed, EMBASE, Cochrane Library, WanFang Database, CNKI) dating from their establishment to June 2018 were searched to find all randomized controlled trials (RCTs) reporting the efficacy of GLP-1 receptor agonists versus metformin for patients with PCOS. Therapeutic variables included menstrual cycle, sex hormone and clinical manifestations, glucose metabolism and other metabolic indexes. Eight RCTs among 462 related articles were included in the meta-analysis. Compared with metformin, GLP-1 receptor agonists were more effective in improving insulin sensitivity (standard mean difference [SMD] -0.40, 95% confidence interval [CI] -0.74 to -0.06, P = 0.02) and reducing body mass index (SMD -1.02, 95% CI -1.85 to -0.19, P = 0.02) and abdominal girth (SMD -0.45, 95% CI -0.89 to -0.00, P = 0.05). GLP-1 receptor agonists were associated with a higher incidence of nausea and headache than metformin, but there were no significant differences in other data. Therefore, compared with metformin, GLP-1 receptor agonists might be a good choice for obese patients with PCOS, especially those with insulin resistance. The available evidence is, however, inconclusive given its moderate to low quality. More high-quality research is needed to assess the efficacy of a GLP-1 receptor agonist on women with PCOS.

Abstract
Polycystic ovary syndrome (PCOS), a multisystem disease, is a major reason for female infertility around the world. It is no longer considered simply as a disease of ovary. Now researchers growing awareness of the multisystem features of this disease. PCOS has a higher relationship with metabolic disturbance and hypothalamic-pituitary-ovarian axis (HPOA) function disorders. This syndrome results in hyperandrogenemia (HA), hyperinsulinemia/insulin resistance (IR), increased estrone, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) ratio imbalance, infertility, cardiovascular diseases, endometrial dysfunction, obesity, and including a litany of other health issues. Furthermore, PCOS has been garnered in recent times. Interventions like metformin, orlistat, hormonal contraceptives, GLP1 agonists, and VitD have been applied to ameliorate or reverse the pathological characterization of PCOS. Moreover, drug-combined therapy of PCOS is superior to single drug administration. This review will focus on the recent progress in pathogenesis and therapy of PCOS.
