Phase angle and body composition in long-term type 1 diabetes in adults: a comparative study in a Brazilian public reference outpatient clinic.

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.

Contrasting Bone Profiles in PCOS Are Related to BMI: A Systematic Review and Meta-analysis.

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.

The role of the visceral adiposity index in the assessment of metabolic syndrome of polycystic ovary syndrome patients: a new anthropometric index.

Purpose: Polycystic ovary syndrome (PCOS) is a common endocrine disorder often linked to metabolic syndrome (MS), raising the risk of cardiovascular disease and type II diabetes. Certain indicators, such as the lipid accumulation product (LAP) and homeostatic model assessment for insulin resistance (HOMA-IR), can predict MS in PCOS patients. This study aimed to assess the predictive power of the visceral adiposity index (VAI) in comparison to LAP and HOMA-IR as predictors of MS in PCOS patients.

Understanding hirsutism in PCOS.

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.

A comparative study of cardiovascular risk stratification methods in type 1 diabetes mellitus patients.

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.

Bone strength is reduced in a neonatal androgenized rat model.

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.

Comparison of image-based modified Ferriman-Gallway score evaluation with in-person evaluation: an alternative method for hirsutism diagnosis.

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.

Insulin Resistance and Its Association With Osteoporosis in People Living With HIV.

Background: Despite the gain in life expectancy that people living with HIV (PLHIV) have had in the past few years, the disease is accompanied by an increase in the prevalence of noninfectious chronic diseases. PLHIV have a higher prevalence of osteoporosis, fracture, diabetes mellitus, and insulin resistance than the general population. It is unknown if insulin resistance is associated with osteoporosis and fractures in PLHIV.

Higher score of diabetes eating problem survey-revised (DEPS-R) is associated with poor glycemic control among Brazilian patients with type 1 diabetes (T1DM): A brief report.

Background And Aims: The diabetes eating problem survey-revised (DEPS-R) questionnaire is a specific and valuable tool for assessing disturbed eating behavior in type 1 diabetes mellitus. The literature suggests an association between a higher DEPS-R score and worse metabolic control; however, these figures have not been described in patients from Latin America.

Methods: We evaluated 58 patients with type 1 diabetes mellitus from a Brazilian outpatient clinic using the DEPS-R questionnaire.

Heat stress modulates polymorphonuclear cell response in early pregnancy cows: I. interferon pathway and oxidative stress.

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.

Incidence of fractures in women in the post-menopause: a cohort study in primary care in southern Brazil.

Unlabelled: The incidences of total fracture, major fracture, and hip fractures in primary care in Southern Brazil were 22.3, 15.0, and 3.

Cryoprotectant agents for ovarian tissue vitrification: Systematic review.

Studies on the cryopreservation of ovarian tissue usually compare slow freezing versus vitrification and aim to optimize protocols, evaluate combinations or concentrations of cryoprotectant agents (CPAs), exposure time, and the addition of synthetic polymers. This systematic review aimed to identify the different CPAs used for the vitrification of human or primate ovarian tissue and to compare their results in terms of follicular survival and functional preservation. We searched Pubmed and EMBASE for randomized clinical trials or cohort studies comparing CPAs for human and/or primate ovarian vitrification.

Ovariectomy Improves Metabolic and Oxidative Stress Marker Disruption in Androgenized Rats: Possible Approach to Postmenopausal Polycystic Ovary Syndrome.

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.

Trabecular Bone is Increased in a Rat Model of Polycystic Ovary Syndrome.

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.

Heat stress on oocyte or zygote compromises embryo development, impairs interferon tau production and increases reactive oxygen species and oxidative stress in bovine embryos produced in vitro.

Interferon tau (IFNT) is the cytokine responsible for the maternal recognition of pregnancy in ruminants and plays a role modulating embryo-maternal communication in the oviduct inducing a local response from immune cells. We aimed to investigate IFNT production, reactive oxygen species, and oxidative stress under the influence of heat stress (HS) during different stages of bovine in vitro embryo production. HS was established when the temperature was gradually raised from 38.

Sarcopenia and Its Association with Vertebral Fractures in People Living with HIV.

The prevalence of chronic diseases is increasing in people living with HIV (PLHIV) in the post ART era. Sarcopenia is prevalent in the elderly and is associated with many chronic diseases. Our study aimed to evaluate the frequency of sarcopenia in PLHIV and its association with bone mineral density and fracture.
