Impact of bariatric surgery on anthropometric, metabolic, and reproductive outcomes in polycystic ovary syndrome: a systematic review and meta-analysis.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in females. Modest weight loss improves reproductive and metabolic PCOS features. While lifestyle modifications and pharmacotherapies remain first-line weight loss strategies, bariatric surgery is emerging as a potentially effective treatment. We performed a systematic review and meta-analysis of published literature to examine the impact of bariatric surgery in PCOS to inform the 2023 International PCOS Evidence-based Guidelines. Electronic databases were searched for observational studies and trials comparing pharmacologic or lifestyle treatments to bariatric surgery in women with PCOS or bariatric surgery in women with or without PCOS. Anthropometric, reproductive, hormonal, and metabolic outcomes were included and, where possible, meta-analyzed using random-effects models. Risk of bias and evidence quality were assessed. Ten studies were included involving 432 women with and 590 women without PCOS. Comparisons between bariatric surgery and pharmacologic or lifestyle treatments were only reported in one study each, and most reproductive outcomes were limited to a single study; therefore, meta-analyses could not be performed. Meta-analysis found that women with PCOS experience similar improvements in anthropometric, hormonal, and metabolic outcomes after bariatric surgery compared to those without PCOS. Existing research is limited and of low quality with high risk of bias, especially in comparison to existing PCOS treatments and with respect to reproductive outcomes including pregnancy, highlighting the need for additional studies to inform clinical recommendations.

Inositol for Polycystic Ovary Syndrome: a systematic review and meta-analysis to inform the 2023 update of the International Evidence-Based PCOS Guidelines.

CONTEXT: Insulin resistance is common in women with Polycystic Ovary Syndrome (PCOS). Inositol may have insulin sensitising effects; however, its efficacy in the management of PCOS remains indeterminate. OBJECTIVE: To inform the 2023 International Evidence-based Guidelines in PCOS, this systematic review and meta-analysis evaluated the efficacy of inositol, alone or in combination with other therapies, in the management of PCOS. DATA SOURCES: Medline, PsycInfo, EMBASE, All EBM, and CINAHL from inception until August 2022. STUDY SELECTION: Thirty trials (n=2230; 1093 intervention, 1137 control), with 19 pooled in meta-analyses were included. DATA EXTRACTION: Data were extracted for hormonal, metabolic, lipids, psychological, anthropometric, reproductive outcomes and adverse effects by one reviewer, independently verified by a second. DATA SYNTHESIS: Thirteen comparisons were assessed, with three in meta-analyses. Evidence suggests benefits for myo-inositol or D-chiro-inositol (DCI) for some metabolic measures and potential benefits from DCI for ovulation but inositol may have no effect on other outcomes. Metformin may improve waist-hip ratio and hirsutism compared to inositol but there is likely no difference for reproductive outcomes, and the evidence is very uncertain for BMI. Myo-inositol likely causes fewer gastrointestinal adverse events compared with metformin; however, these are typically mild and self-limited. CONCLUSIONS: The evidence supporting the use of inositol in the management of PCOS is limited and inconclusive. Clinicians and their patients should consider the uncertainty of the evidence together with individual values and preferences when engaging in shared decision-making regarding the use of inositol for PCOS.

Assisted Reproductive Technology in the Presence of Polycystic Ovary Syndrome: Current Evidence and Knowledge Gaps.

OBJECTIVE: In this narrative review, we discuss the current evidence as well as the knowledge gaps concerning assisted reproductive technology (ART) indications, protocols, and results in the presence of polycystic ovary syndrome (PCOS). METHODS: An electronic literature search was performed for English-language publications in the last decade in databases such as PubMed, Medline, the Web of Sciences, Embase, and Scopus. RESULTS: We found evidence that ovarian steroidogenesis and folliculogenesis are deeply altered by PCOS; however, the oocyte quality and pregnancy rates after ART are not affected. Patients with PCOS are more sensitive to the action of exogenous gonadotropins and more likely to develop ovarian hyperstimulation syndrome. This risk can be mitigated by the adoption of the gonadotropin-releasing hormone antagonist protocols for pituitary blockade and ovarian stimulation, along with frozen embryo transfer, without compromising the odds of achieving a live birth. Pregnancy complications, such as miscarriage, gestational diabetes, preeclampsia, and very preterm birth, are more frequent in the presence of PCOS, requiring more intense prenatal care. It remains uncertain whether weight reduction or insulin sensitizers used before ART are beneficial for the treatment outcomes. CONCLUSION: Although PCOS is not a drawback for ART treatments, the patients need special care to avoid complications. More in-depth studies are needed to uncover the mechanisms of follicular growth, gamete maturation, and endometrial differentiation during ART procedures in the presence of PCOS.

Metformin and Combined Oral Contraceptive Pills in the Management of Polycystic Ovary Syndrome: A Systematic Review and Meta-analysis.

CONTEXT: Polycystic ovary syndrome (PCOS) affects more than 1 in 10 women. OBJECTIVE: As part of the 2023 International PCOS Guidelines update, comparisons between combined oral contraceptive pills (COCP), metformin, and combination treatment were evaluated. DATA SOURCES: Ovid Medline, Embase, PsycINFO, All EBM, and CINAHL were searched. STUDY SELECTION: Women with PCOS included in randomized controlled trials (RCTs). DATA EXTRACTION: We calculated mean differences and 95% CIs regarding anthropometrics, metabolic, and hyperandrogenic outcomes. Meta-analyses and quality assessment using GRADE were performed. DATA SYNTHESIS: The search identified 1660 publications; 36 RCTs were included. For hirsutism, no differences were seen when comparing metformin vs COCP, nor when comparing COCP vs combination treatment with metformin and COCP. Metformin was inferior on free androgen index (FAI) (7.08; 95% CI 4.81, 9.36), sex hormone binding globulin (SHBG) (-118.61 nmol/L; 95% CI -174.46, -62.75) and testosterone (0.48 nmol/L; 95% CI 0.32, 0.64) compared with COCP. COCP was inferior for FAI (0.58; 95% CI 0.36, 0.80) and SHBG (-16.61 nmol/L; 95% CI -28.51, -4.71) compared with combination treatment, whereas testosterone did not differ. Metformin lowered insulin (-27.12 pmol/L; 95% CI -40.65, -13.59) and triglycerides (-0.15 mmol/L; 95% CI -0.29, -0.01) compared with COCP. COCP was inferior for insulin (17.03 pmol/L; 95% CI 7.79, 26.26) and insulin resistance (0.44; 95% CI 0.17, 0.70) compared with combination treatment. CONCLUSIONS: The choice of metformin or COCP treatment should be based on symptoms, noting some biochemical benefits from combination treatment targeting both major endocrine disturbances seen in PCOS (hyperinsulinemia and hyperandrogenism).

The impact of neonatal 17-hydroxyprogesterone cutoff determination in a public newborn screening program for congenital adrenal hyperplasia in Southern Brazil: 3 years' experience.

Congenital adrenal hyperplasia (CAH) occurs due to enzyme defects in adrenal steroidogenesis. The 21-hydroxylase deficiency accounts for 90-95% of cases, triggering accumulation of 17-hydroxyprogesterone (17-OHP). Early diagnosis through neonatal screening allows adequate treatment and reduced mortality. The purpose of the study was to determine 17-OHP cutoffs for the diagnosis of CAH in a public newborn screening program in Southern Brazil. A retrospective, descriptive, cross-sectional study was conducted to analyze 17-OHP levels in dried blood samples collected on filter paper of 317,745 newborns screened at a public newborn screening center from May 2014 to April 2017. Neonatal 17-OHP was measured in DBS samples using a time-resolved fluoroimmunoassay (GSP® kit 3305-0010; PerkinElmer). Different cutoffs were determined and stratified by birth weight. The incidence of CAH was 1:15,887 live births in the state of Rio Grande do Sul, with 20 cases of classical CAH diagnosed during the study period. Most newborns (80.73%) were white, and the prematurity rate was 9.8% in the study population. The combination of different percentiles, 98.5th for birth weight 2001-2500 g and 99.8th for the other birth weight groups, decreased false-positive results and increased specificity compared with current reference values to identify classical CAH cases. The local 17-OHP cutoffs determined were higher than those currently used by this screening program for all birth weight groups. The calculation of reference values from local population data and the combination of percentiles proved to be a valuable tool for proper diagnosis of CAH and reduction in the number of false positives.

Lean mass and associated factors in women with PCOS with different phenotypes.

Although current evidence suggests increased risk of obesity, insulin resistance, and metabolic alterations in patients with polycystic ovary syndrome (PCOS), especially of a hyperandrogenic phenotype, the impact of each one of these variables on muscle mass remains uncertain. In this case-control study, we evaluated clinical and hormonal characteristics related to lean body mass according to the different PCOS phenotypes. We performed clinical, metabolic, and hormonal assessments and evaluated body compartments by dual-energy X-ray absorptiometry in 133 women of reproductive age. Creatinine served as an indirect marker of lean mass. Median age was 28 (range, 17-37) years. Women with phenotypes A and B (n = 59) had higher body mass index (BMI) and metabolic syndrome prevalence than those with phenotype C (n = 23) and controls (n = 51) (p<0.005). Women with phenotypes A and B also had higher Ferriman-Gallwey score (p<0.001), insulin levels (p = 0.006), HOMA-IR (p = 0.008), testosterone (p = 0.008), free androgen index (FAI) (p<0.001), fat mass index (FMI) (p = 0.015), android-to-gynoid fat ratio (p = 0.036), and bone mineral density (BMD) at lumbar spine (p = 0.027) and total femur (p = 0.013) than controls. Median appendicular lean mass index (ALMI) was higher in phenotypes A and B than in controls (7.01 [IQR, 6.33-8.02] vs. 6.69 [IQR, 5.94-7.09], p = 0.024), but it did not differ significantly from that in phenotype C (6.60 [IQR, 6.16-7.22], p = 0.222). Even after adjusting for BMI, ALMI correlated positively with creatinine in women with phenotypes A and B (rho = 0.319, p = 0.023) but not in those with phenotype C (p = 0.238) or controls (p = 0.097). In multivariate linear regression analyses, ALMI was positively associated with insulin, FAI, FMI, and total femur BMD. The present results suggest that fasting insulin, FAI, fat mass, and total femur BMD were positively associated with increased lean mass in women with PCOS phenotypes A and B.

The impact of metformin with or without lifestyle modification versus placebo on polycystic ovary syndrome: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: Available evidence has shown that metformin improves insulin sensitivity and weight management in polycystic ovary syndrome (PCOS). Nevertheless, key knowledge gaps remain regarding its efficacy and the specific outcomes in this population. This review evaluates the effectiveness of metformin and lifestyle modification compared with placebo in the management of PCOS and will inform the forthcoming, 2023 evidence-based PCOS guidelines. DESIGN: Systematic review and meta-analysis of the literature. METHODS: A search was performed in MEDLINE, EMBASE, PsycINFO, All EBM, and CINAHL. The review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and included randomized controlled trials published in English through July 2022. RESULTS: Moderate certainty of evidence showed a larger reduction of body mass index (BMI) (mean difference [MD] -0.53, 95% confidence interval [CI] -0.95 to -0.12 kg/m2), homeostatic model assessment for insulin resistance (MD -0.50, 95% CI -0.91 to -0.09) (critical outcomes), and fasting glucose (MD -0.13, 95% CI -0.19 to -0.07 mmol/L) with metformin compared to placebo with increased mild gastrointestinal adverse effects (odds ratio [OR] 7.67, 95% CI 2.74-21.46). Low certainty of evidence showed a larger reduction of waist-hip ratio (MD -0.02, 95% CI -0.03 to -0.00), total cholesterol (MD -0.24, 95% CI -0.43 to -0.05 mmol/L), low-density lipoprotein (MD -0.16, 95% CI -0.30 to -0.01 mmol/L), and triglycerides (MD -0.11, 95% CI -0.20 to -0.02 mmol/L) with metformin than placebo. CONCLUSIONS: Metformin should be considered an efficacious adjunct to lifestyle interventions in adults with PCOS, especially for those with a higher BMI, to improve weight loss, insulin resistance, and lipids.

A speech therapy for transgender women: an updated systematic review and meta-analysis.

BACKGROUND: We systematically reviewed the literature and performed a meta-analysis on the effects of speech therapy and phonosurgery, for transgender women, in relation to the fundamental frequency gain of the voice, regarding the type of vocal sample collected, and we compared the effectiveness of the treatments. In addition, the study design, year, country, types of techniques used, total therapy time, and vocal assessment protocols were analyzed. METHODS: We searched the PubMed, Lilacs, and SciELO databases for observational studies and clinical trials, published in English, Portuguese, or Spanish, between January 2010 and January 2023. The selection of studies was carried out according to Prisma 2020. The quality of selected studies was assessed using the Newcastle-Ottawa scale. RESULTS: Of 493 studies, 31 were deemed potentially eligible and retrieved for full-text review and 16 were included in the systematic review and meta-analysis. Six studies performed speech therapy and ten studies phonosurgery. The speech therapy time did not influence the post-treatment gain in voice fundamental frequency (p = 0.6254). The type of sample collected significantly influenced the post-treatment voice frequency gain (p < 0.01). When the vocal sample was collected through vowel (p < 0.01) and reading (p < 0.01), the gain was significantly more heterogeneous between the different types of treatment. Phonosurgery is significantly more effective in terms of fundamental frequency gain compared to speech therapy alone, regardless of the type of sample collected (p < 0.01). The average gain of fundamental frequency after speech therapy, in the /a/ vowel sample, was 27 Hz, 39.05 Hz in reading, and 25.42 Hz in spontaneous speech. In phonosurgery, there was a gain of 71.68 Hz for the vowel /a/, 41.07 Hz in reading, and 39.09 Hz in spontaneous speech. The study with the highest gain (110 Hz) collected vowels, and the study with the lowest gain (15 Hz), spontaneous speech. The major of the included studies received a score between 4 and 8 on the Newcastle-Ottawa Scale. CONCLUSION: The type of vocal sample collected influences the gain result of the fundamental frequency after treatment. Speech therapy and phonosurgery increased the fundamental frequency and improved female voice perception and vocal satisfaction. However, phonosurgery yielded a greater fundamental frequency gain in the different samples collected. The study protocol was registered at Prospero (CRD42017078446).

Associations between bone mass, hormone levels, and body composition in postmenopausal women.

OBJECTIVES: The aim of this study was to explore body composition parameters and hormone levels as risk factors for low bone mass (osteopenia/osteoporosis) in postmenopausal women. METHODS: We analyzed biorepository samples from 139 postmenopausal women with no clinical evidence of cardiovascular disease. Inclusion criteria were menopause occurring after 40 years of age and no use of hormone therapy in the past 3 months. Bone mineral density and body composition were assessed by dual-energy x-ray absorptiometry. Sex hormone-binding globulin (SHBG) and follicle-stimulating hormone (FSH) levels were measured in all participants. Serum estradiol was measured by gas chromatography/tandem mass spectrometry in a subset of 57 participants. Free estrogen index was calculated by dividing estradiol by SHBG × 100. RESULTS: Body mass index (25.0 [22.5-26.5] vs 27.7 [26.6-31.9] kg/m 2 , P < 0.001), estradiol (3.0 [2.7-4.5] vs 6.0 [2.7-15.0] pg/mL, P = 0.006), waist circumference (84 ± 9 vs 93 ± 12 cm, P < 0.001), appendicular lean mass (ALM) (15.739 ± 2.129 vs 17.184 ± 2.104 kg, P = 0.001), and fat mass index (9.36 [7.29-11.43] vs 11.38 [9.95-15.33] kg/m 2 , P < 0.001) were lower in women with low bone mass by dual-energy x-ray absorptiometry. Univariate analysis showed that free estrogen index, time since menopause, SHBG, and fat mass were significant predictors of low bone mass, and ALM was a significant predictor against low bone mass. Appendicular lean mass persisted as an independent predictor against low bone mass in multivariate models with fat mass and SHBG. In turn, fat mass was no longer significant in this multivariate model after inclusion of SHBG. No association of FSH with low bone mass was observed. CONCLUSIONS: Appendicular lean mass was a significant independent predictor against low bone mass in postmenopausal women. Further prospective studies are needed to investigate whether lean mass, fat mass, and FSH have a direct effect on bone mass in postmenopausal women, adding to the consequences of hypoestrogenism in this group.

The Effect of Gender-Affirming Hormone Therapy on the Risk of Subclinical Atherosclerosis in the Transgender Population: A Systematic Review.

OBJECTIVE: The impact of gender-affirming hormone therapy (GAHT) on cardiovascular (CV) health is still not entirely established. A systematic review was conducted to summarize the evidence on the risk of subclinical atherosclerosis in transgender people receiving GAHT. METHODS: A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, and data were searched in PubMed, LILACS, EMBASE, and Scopus databases for cohort, case-control, and cross-sectional studies or randomized clinical trials, including transgender people receiving GAHT. Transgender men and women before and during/after GAHT for at least 2 months, compared with cisgender men and women or hormonally untreated transgender persons. Studies reporting changes in variables related to endothelial function, arterial stiffness, autonomic function, and blood markers of inflammation/coagulation associated with CV risk were included. RESULTS: From 159 potentially eligible studies initially identified, 12 were included in the systematic review (8 cross-sectional and 4 cohort studies). Studies of trans men receiving GAHT reported increased carotid thickness, brachial-ankle pulse wave velocity, and decreased vasodilation. Studies of trans women receiving GAHT reported decreased interleukin 6, plasminogen activator inhibitor-1, and tissue plasminogen activator levels and brachial-ankle pulse wave velocity, with variations in flow-mediated dilation and arterial stiffness depending on the type of treatment and route of administration. CONCLUSIONS: The results suggest that GAHT is associated with an increased risk of subclinical atherosclerosis in transgender men but may have either neutral or beneficial effects in transgender women. The evidence produced is not entirely conclusive, suggesting that additional studies are warranted in the context of primary prevention of CV disease in the transgender population receiving GAHT.

Effect of Suppressive Levothyroxine Therapy on Bone Mineral Density in Young Patients with Differentiated Thyroid Carcinoma.

Suppressive levothyroxine therapy (sT4) is a cornerstone in the management of differentiated thyroid cancer (DTC). Long-term sT4 may affect bone mineral density (BMD). We evaluated the effect of sT4 on the bone mass of young DTC patients. In this cross-sectional study, BMD was evaluated via dual-energy X-ray absorptiometry in DTC patients younger than 25 years at diagnosis and undergoing sT4 for ≥1 year. The two control groups comprised patients matched for sex, age, and body-mass-index who were thyroidectomized for indications other than DTC and undergoing L-T4-replacement therapy, and healthy individuals with no prior known thyroid disease. Ninety-three participants were included (thirty-one in each group). There were no differences in the mean age, female sex (77.4% in all groups), or BMI between the sT4 group and each control group. The median TSH level was lower (0.4 [0.04-6.5] vs. 2.7 [0.8-8.5] mIU/mL, p = 0.01) and the mean L-T4 mcg/Kg levels were higher (2.4 ± 0.6 vs. 1.6 ± 0.3, p = 0.01) in the sT4 group compared to the L-T4-replacement therapy group. Lumbar spine, femoral neck, and total femur BMD were all similar among the groups. sT4 does not impact BMD in young DTC patients after a median time of suppression of 8 years. These findings may help in the decision-making and risk/benefit evaluation of sT4 for this population.

Physical frailty in patients with systemic sclerosis.

INTRODUCTION: Systemic sclerosis (SSc) is a chronic disease characterized by autoimmunity, vasculopathy and fibrosis of several organs, such as skin, lungs, and heart. During the disease course, patients with SSc are prone to accumulating multiple organ damage and increasing their vulnerability to adverse outcomes. This increased vulnerability to adverse outcomes when exposed to a stressor among people of the same age is known as frailty. One of the most used definitions of frailty is the physical frailty phenotype (PFP), including 5 components: unintentional weight loss, exhaustion, muscle weakness, slow walking speed, and low physical activity. There is scarce data about frailty in patients with SSc. OBJECTIVES: To determine the prevalence and clinical profile of PFP in a sample of patients with SSc. To investigate the diagnostic accuracy of the Fatigue, Resistance, Ambulation, Illness and Loss of weight (FRAIL) scale, Edmonton frailty scale (EFS) and Short Physical Performance Battery (SPPB) using the PFP as the reference standard. METHODS: Cross-sectional study including 94 patients with SSc according to the 2013 ACR-EULAR classification criteria or the criteria suggested by Le Roy and Medsger for early disease. Gastrointestinal symptoms were assessed by the UCLA GIT 2.0 questionnaire, malnutrition was defined according to European Society of Clinical Nutrition and Metabolism (ESPEN) recommendations, and physical performance was assessed by SPPB. PFP assessment was according to the original definition, except for physical activity domain, assessed with the International Physical Activity Questionnaire (IPAQ). FRAIL scale and EFS were also applied to the same individuals. For diagnostic assessment of FRAIL, EFS and SPPB, we estimated the area under the receiver operating characteristic curve (AUC), considering PFP as the reference standard and dichotomizing the results in frail vs. non-frail. RESULTS: According to PFP, 33 patients (35.1%) were considered frail and 53 patients (56.4%) pre-frail. According to FRAIL scale, 27 patients (28.7%) were considered frail and 53 patients (56.4%) pre-frail. According to EFS, 28 patients (29.7%) were classified as vulnerable and 15 (15.9%) as frail: mild in 8 (8.5%), moderate in 5 (5.3%) and severe in 2 (2.1%). According to SPPB, 19 patients (20.2%) were considered frail. The AUC against PFP was: 0.829 (95% CI 0.743-0.916) for FRAIL scale, 0.859 (95% CI 0.784-0.934) for EFS and 0.791 (95% CI 0.697-0.885) for SPPB. The PFP was associated with current use of glucocorticoids (p=0.011), UCLA GIT 2.0 score (p=0.001), HAQ (p<0.0001), patient and physician-assigned VAS (p<0.0001, both), malnutrition (p=0.007), hospitalizations in the past year (p=0.008) and dependence on BADL and IADL (p=0.027 and p<0.0001, respectively). The PFP was not associated with gender (p=0.679), age (p=0.303), disease duration (p=0.504), Rodnan skin score (p=0.918), diffuse subtype (p=0.116), polypharmacy (p=845) and sarcopenia (p=0.328). CONCLUSION: Frailty is prevalent in patients with long-standing SSc and is associated with disability, limitations in daily activities and hospitalizations in the past year. Also, malnutrition and more severe gastrointestinal symptoms were more common in frail patients. Both FRAIL scale and EFS showed excellent diagnostic accuracy against PFP as the reference standard, however the FRAIL scale presents a higher sensitivity and seems to be more feasible and practical than EFS and SPPB in clinical practice.

Hirsutism, Normal Androgens and Diagnosis of PCOS.

Hirsutism is defined as the presence of terminal hair with male pattern distribution in women. While in the general population, hirsutism affects around 4-11% of women, it is the main manifestation of hyperandrogenism in women with polycystic ovary syndrome (PCOS), with a prevalence estimated at 65-75%. Hirsutism in PCOS is associated with both androgen excess and individual response of the pilosebaceous unit to androgens. The modified Ferriman-Gallwey (mFG) scoring system has been widely used in clinical practice to visually score excessive terminal hair, thus standardizing hirsutism evaluation and facilitating data comparison. Although a universal mFG score cutoff would be useful for comparisons, ethnic variations, as well as skin type and other factors, should be considered when evaluating hirsutism in distinct populations. In turn, androgen levels, measured by conventional techniques, have been shown to correlate poorly with the severity of hirsutism. Indeed, while most women with PCOS and hirsutism also have higher than reference values for serum androgen levels, some of them may not present with biochemical hyperandrogenism, representing a challenge to the diagnosis of PCOS. In this article, we critically review this not uncommon condition in women with PCOS presenting with hirsutism but normal androgen levels.

Body composition in patients with hepatic glycogen storage diseases.

OBJECTIVES: The present study aimed to evaluate the body composition of hepatic glycogen storage disorders (GSDs) through dual energy x-ray absorptiometry. METHODS: This was an exploratory, observational, cross-sectional study. Twenty-four patients with GSD (type Ia: n = 13, Ib: n = 5, III: n = 2, and IX-α/ß/γ: n = 4; female sex: n = 13; age <8 y: n = 3, 8-19 y: n = 14, and >19 y: n = 7) were included. Three-day dietary records were collected in the week preceding dual energy x-ray absorptiometry. Body composition findings were correlated with clinical parameters, uncooked cornstarch (UCCS) regimen, dietary intake, and markers of treatment adherence. RESULTS: An elevated fat mass (FM) index was found in 16 of 21 patients (age 8-19 y: n = 10 and >19 y: n = 6; GSD type Ia: n = 12, Ib: n = 2, III: n = 1, and IX-γ: n = 1). A lean mass (LM) index evaluation showed no LM deficits in relation to corresponding reference populations. Relative skeletal muscle index values were decreased in 2 of 7 adult patients (type Ib: n = 1 and IX-α: n = 1). UCCS (g/d) correlated positively with the FM index (rs = 0.7; P ≤ 0.01). In contrast, relative UCCS intake (g/kg body weight) was negatively associated with LM/kg (rs = -0.8; P ≤ 0.01). CONCLUSIONS: These findings suggest a high frequency of elevated FM in patients with hepatic GSDs. We also suggest that treatment with UCCS is associated with excess weight in these patients. Additionally, the treatment strategy can impair protein intake, and lead to a decrease in LM.

[Contraception in the context of PCOS]. / Contraception dans le contexte du syndrome des ovaires polykystiques.

Polycystic ovary syndrome is a frequent endocrinopathy, affecting between 8% and 13% of women of childbearing age and characterized by hyperandrogenism, chronic anovulation and polycystic ovary morphology. Women with PCOS also have a higher prevalence of obesity, metabolic disorders and an increased risk of diabetes, systemic hypertension and dyslipidemia. The first-line treatment for women with PCOS who do not plan to conceive in the short term includes lifestyle changes and combined oral contraceptives, offering, in addition to contraception, endometrial protection and reduction of hyperandrogenism. Progestin-only contraceptives are recommended for women with contraindications to estrogen contained in combined oral contraceptives. Cosmetic procedures can be added to pharmacological treatment for hirsutism. Severe cases may require anti-androgen drugs which will be combined with contraception. For overweight patients with cardiometabolic risk factors, including insulin resistance or dysglycemia, metformin may also be combined with contraception. In conclusion, the choice of contraception in women with PCOS includes an approach tailored to the individual needs of each patient.

TITLE: Contraception dans le contexte du syndrome des ovaires polykystiques. ABSTRACT: Le syndrome des ovaires polykystiques (SOPK) est une endocrinopathie fréquente, affectant entre 8 et 13 % des femmes en âge de procréer. Elle se caractérise par une hyperandrogénie, une anovulation chronique, et une morphologie polykystique des ovaires. Les femmes qui en sont atteintes ont aussi une prévalence plus élevée d'obésité, de troubles métaboliques, et un risque accru de diabète, d'hypertension artérielle systémique et de dyslipidémie. Le traitement, en première intention, de la femme atteinte du SOPK, en l'absence de projet de grossesse à court terme, consiste en des modifications du mode de vie et en des contraceptions orales combinées offrant, en plus de la contraception, la protection de l'endomètre et la réduction de l'hyperandrogénie. Les contraceptions progestatives seules sont recommandées pour les femmes ayant des contre-indications aux estrogènes qui sont contenus dans les contraceptifs oraux combinés. Des soins esthétiques peuvent aussi être associés au traitement pharmacologique, en cas d'hirsutisme. Les cas les plus graves peuvent nécessiter des médicaments anti-androgènes qui seront associés à la contraception. Pour les patientes en surpoids et ayant des facteurs de risque cardiométaboliques, notamment une résistance à l'insuline ou une hyperglycémie, la metformine peut être associée à la contraception. Le choix de la contraception chez ces femmes repose donc sur une approche adaptée aux besoins individuels de chaque patiente.

Metabolic Features of Women With Polycystic Ovary Syndrome in Latin America: A Systematic Review.

Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder that commonly affects women of childbearing age and has been associated with metabolic and reproductive abnormalities. Only a few studies have investigated metabolic traits in women with PCOS in Latin America. Therefore, we conducted a systematic review to provide an overview of the available evidence on the metabolic profile of Latin American women with PCOS. Methods: We searched PubMed, Cochrane Central Register of Controlled Trials, and Embase databases for cross-sectional, case-control, or cohort studies focusing on populations of countries in South and Central America and Mexico, published until October 31, 2019. We selected studies that reported the diagnostic criteria for PCOS. In the absence of a control group, we included studies if they reported relevant metabolic data. Results: The initial search yielded 4878 records, of which 41 studies were included in the systematic review. Sample sizes ranged from 10 to 288 in PCOS groups and from 10 to 1500 in control groups. The prevalence of phenotypes A and B (classic PCOS) ranged from 65.8% to 87.5% as reported in studies from Argentina, Brazil, and Chile. Metabolic syndrome ranged from 33.3% to 44.0% for phenotype A, from 15.0% to 58.0% for phenotype B, from 11.9% to 36.0% for phenotype C, and from 14.2% to 66.0% for phenotype D. Women with PCOS had higher body mass index, waist circumference, blood pressure, glucose, and homeostasis model assessment index as well as a more adverse lipid profile than those without PCOS. Conclusions: Evidence from the present systematic review suggests that anthropometric and metabolic profiles are worse in women with PCOS who live in different Latin American countries than in women without PCOS living in the same region. Additional studies assessing metabolic comorbidities, such as diabetes, and distinct PCOS phenotypes in different Latin American countries are warranted and may produce invaluable information for primary and secondary prevention of PCOS in the region.
