Introduction: Type 1 Diabetes Mellitus (DM1) affects a small percentage of the population. Nevertheless, its prevalence is currently growing with alarming data on uncontrolled cases. The importance of body composition and Phase Angle (PA), assessed by Bioelectrical Impedance (BIA), in long- term DM1 patients lies in the fact that alterations in cellular integrity and body compartments may affect risk profiles and metabolic control.

Article Synopsis
  • The study aimed to assess the effectiveness of a self-assessment questionnaire for hirsutism in Latin-American women using updated guidelines from two major health organizations.
  • A total of 188 premenopausal women completed the questionnaire, scoring hair growth in nine areas, and their results were compared to clinician evaluations, revealing an overall accuracy of 80% for the self-assessment using ES criteria.
  • Despite high sensitivity, the self-assessment showed low specificity and limited diagnostic value, suggesting it may be more suitable for screening purposes in research rather than clinical diagnosis.

Context: Controversial results have emerged regarding whether polycystic ovary syndrome (PCOS) is protective or increases the risk of bone frailty.

Objective: This study investigated whether the PCOS condition affects bone parameters of premenopausal women. This is an update for a previous meta-analysis published in 2019.

Introduction: Hirsutism is a prevalent condition among women and represents a primary clinical feature of polycystic ovary syndrome (PCOS).

Areas Covered: Our study aims to address the principal challenges associated with this hyperandrogenic manifestation in PCOS women. Our narrative review based on the available indexed literature explored the complexities of establishing mFG cutoff values for various ethnic groups, investigated hirsutism during peri- and postmenopausal stages, and examined the role of oxyandrogens.

The Steno Diabetes Center Copenhagen developed the Steno T1 Risk Engine (ST1RE) to predict cardiovascular events, encompassing fatal and nonfatal ischemic heart disease, ischemic stroke, heart failure, and peripheral arterial disease in type 1 diabetes mellitus(T1DM).The current study investigated the agreement between ST1RE and the Brazilian Society for Endocrinology and Metabology (SBEM) classification. Participants were included in the study if diagnosed with T1DM and had at least one outpatient visit in 2021.

Background: Whether polycystic ovary syndrome (PCOS) affects bone health during a woman's lifespan remains controversial. An androgenized rodent model replicated many metabolic and reproductive features of women with PCOS, and we aimed to use it to investigate the impact of androgens on microarchitecture (by micro-CT), bone mechanical strength, bone formation and resorption markers in rats with intact ovaries (SHAM) who underwent oophorectomy.

Methods: Wistar rats ( were employed for the experiments in this study.

The gold standard for diagnosing hirsutism is based on the modified Ferriman-Gallway (mFG) score, requiring trained and in-person evaluation. Our study aimed to evaluate whether using mobile phone images of the nine mFG areas could offer an alternative way to support the diagnostic of hirsutism. All patients from an endocrine outpatient clinic underwent an initial mFG evaluation by two blinded, trained examiners.

One of the major causes of early pregnancy loss is heat stress. In ruminants, interferon tau (IFNT) is the embryo signal to the mother. Once the interferon signaling pathway is activated, it drives gene expression for interferon-stimulated genes (ISGs) and alters neutrophils responses.

This study aims to evaluate metabolic and oxidative stress markers in a postmenopausal rat model of polycystic ovary syndrome (PCOS). Wistar rats were divided in four groups: control ovariectomized (OVX;  = 9), control SHAM ( = 9), androgenized OVX ( = 10), and androgenized SHAM ( = 10). Female rats were androgenized during the neonatal period and compared with controls.

Polycystic ovary syndrome (PCOS) in an intricate disorder characterized by reproductive and metabolic abnormalities that may affect bone quality and strength along with the lifespan. The present study analysed the impact of postnatal androgenization (of a single dose of testosterone propionate 1.25 mg subcutaneously at day 5 of life) on bone development and markers of bone metabolism in adult female Wistar rats.

Background: Polycystic ovary syndrome (PCOS) has reproductive and metabolic aspects that may affect bone health. Controversial results from different studies regarding the risk of fractures, bone mineral density (BMD) or bone markers led to uncertainty whether PCOS might improve or deteriorate bone health.

Objective And Rationale: This study aimed to investigate the impact of PCOS on bone markers, BMD and fracture risk.

The main clinical feature associated with hyperandrogenism in polycystic ovary syndrome (PCOS) in humans is hirsutism, where hair increases its length, pigmentation, and particularly its diameter. Currently, it is not known whether PCOS animal models also exhibit changes in the hair. Therefore, the aim of this study was to explore the wool characteristics in sheep prenatally androgenized (PA) with testosterone propionate.

Although fractures had high mortality and morbidity, many studies proved that fracture risk might be decreased by pharmacological therapy, although a low treatment adherence rate is observed. The aim of this study was to identify factors associated with osteoporosis treatment in postmenopausal women.A cross-sectional study was carried out from March to August 2013 at the primary care setting.

Background: Several studies have described an enhanced inflammatory status and oxidative stress balance disruption in women with polycystic ovary syndrome (PCOS). However, there is scarce information about redox markers in the blood of androgenized animal models. Here, we evaluated the serum/plasma oxidative stress marker and metabolic parameter characteristics of prenatal (PreN) and postnatal (PostN) androgenized rat models of PCOS.

Although health-related quality of life is well studied in subjects with obesity or fractures, there are few studies approaching both diseases together. The aim of this study was to evaluate the health-related quality of life (HRQL) in obese postmenopausal women with fractures. A cross-sectional study was carried out at Santa Maria, Brazil.

In this study, a GnRH agonist, leuprolide acetate (LA), was given as a single depot injection before 48 h of life to Wistar female rats allotted to prenatal (E16-18) and postnatal androgenization (day 5 of life) by the use of testosterone propionate, looking for reproductive endpoints. Remarkably, a single injection of LA increased the estrus cycles in the postnatal group (PostN) from 0% to 25% of the estrus cycles in the postnatal LA treated group (PostN L). LA also reduced the serum testosterone levels and cysts and atretic follicles in PostN L in contrast with rats (>100 days) from the PostN group (p = 0.

The discovery of a receptor that binds prorenin and renin in human endothelial and mesangial cells highlights the possible effect of renin-independent prorenin in the resumption of meiosis in oocytes that was postulated in the 1980s.This study aimed to identify the (pro)renin receptor in the ovary and to assess the effect of prorenin on meiotic resumption. The (pro)renin receptor protein was detected in bovine cumulus-oocyte complexes, theca cells, granulosa cells, and in the corpus luteum.

Obesity and osteoporosis are chronic disorders with increasing prevalence worldwide. The aim of this study was to investigate the association between obesity and fracture in postmenopausal women from Santa Maria, Brazil. A cross-sectional study was carried out at Santa Maria (parallel 29° south), Brazil.
