Circulating prolactin levels and the effect of dopaminergic agonists in systemic lupus erythematosus: a systematic review and meta-analysis.

This systematic review of clinical studies investigated whether circulating PRL levels differed between subjects with systemic lupus erythematosus (SLE) and healthy controls, the correlation between circulating PRL and SLE activity, and the effect of dopaminergic agonists as adjuvant therapy for SLE. We searched PubMed, Scopus, Web of Science, Cochrane, Embase, and Google Scholar for case-control and cross-sectional studies investigating circulating PRL levels in subjects with SLE and/or its correlation with disease activity, and clinical trials examining the effect of dopaminergic agonists on SLE activity assessed by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score. Forty-five studies addressing circulating PRL levels in SLE met our inclusion criteria.

Exposure of elementary school-aged Brazilian children to bisphenol A: association with demographic, social, and behavioral factors, and a worldwide comparison.

Bisphenol A (BPA) is a plasticizer used to synthesize polycarbonate plastics and epoxy resins and is well-known for its endocrine-disrupting action. BPA occurrence in the environment is widespread, and there is a growing concern regarding exposure to this chemical during childhood, given the findings indicating the long-lasting hazards associated with exposure during early life compared to adulthood. We examined urinary BPA concentrations from 319 elementary school-aged Brazilian children, using high-performance liquid chromatography coupled to high-resolution mass spectrometry.

Leukocyte telomere length in subjects with metabolic dysfunction-associated steatotic liver disease.

Background And Study Aims: This study aimed to examine the association between peripheral leukocyte telomere length and indicators of metabolic abnormalities in subjects with metabolic dysfunction-associated steatotic liver disease (MASLD) assessed by magnetic resonance imaging (MRI).

Patients And Methods: This cross-sectional study included adults over 20 years with body mass index (BMI) of over >25 kg/m and sonographic evidence of hepatic steatosis. The subjects were evaluated by clinical and biochemical variables, determination of hepatic fat fraction by MRI and relative peripheral leukocyte telomere length by quantitative real-time polymerase chain reaction.

Fecal microbiota transplantation ameliorates high-fat diet-induced memory impairment in mice.

Gut dysbiosis is linked to metabolic and neurodegenerative diseases and comprises a plausible link between high-fat diet (HFD) and brain dysfunction. Here we show that gut microbiota modulation by either antibiotic treatment for 5 weeks or a brief 3-day fecal microbiota transplantation (FMT) regimen from low-fat (control) diet-fed mice decreased weight gain, adipose tissue hypertrophy, and glucose intolerance induced by HFD in C57BL/6 male mice. Notably, gut microbiota modulation by FMT completely reversed impaired recognition memory induced by HFD, whereas modulation by antibiotics had less pronounced effect.

Body mass trajectory from diagnosis to the end of treatment in a pediatric acute lymphoblastic leukemia cohort.

The advances in pediatric acute lymphoblastic leukemia (ALL) care have substantially increased survival, and the late effects of treatment are a growing concern. Obesity development is frequent following ALL therapy and may significantly contribute to long-term morbidity and mortality. We examined the body mass trajectory of 208 children with ALL, from the diagnosis to the completion of therapy.

Early-life exposure to antibiotics and excess body weight in childhood and adolescence: A systematic review and meta-analysis.

Background: The association between early-life exposure to antibiotics and overweight/obesity is unclear. We conducted a systematic review and meta-analysis to address this issue.

Methods: We searched PubMed, Web of Science, Scopus, and grey literature from inception to August 10, 2022, for cohort studies investigating the association between early-life exposure to antibiotics and weight outcomes.

The effect of long-term exposure to nonylphenol at environmentally relevant levels on mouse liver and adipose tissue.

Exposure to the xenoestrogen nonylphenol (NP) during critical windows of development leads to metabolic abnormalities in adult life. However, less is known about NP exposure outside the developmental period on metabolic outcomes. We investigated the effect of prolonged exposure to NP after sexual maturity and at environmentally relevant concentrations below the 'no observable adverse effects level' (0.

Early-life exposure to endocrine-disrupting chemicals and autistic traits in childhood and adolescence: a systematic review of epidemiological studies.

Aims: Exposure to endocrine-disrupting chemicals (EDCs) during critical neurodevelopmental windows has been associated with the risk of autistic traits. This systematic review of epidemiological studies examined the association between maternal exposure to EDCs during pregnancy and the risk of autism spectrum disorder (ASD) in the offspring.

Methods: We searched PubMed, Web of Science, Scopus, and Google Scholar from inception to November 17, 2022, for studies investigating the association between prenatal exposure to EDCs and outcomes related to ASD.

Early-life metabolic dysfunction impairs cognition and mitochondrial function in mice.

The impact of overnutrition early in life is not restricted to the onset of cardiovascular and metabolic diseases, but also affects critical brain functions related to cognition. This study aimed to evaluate the relationship between peripheral metabolic and bioenergetic changes induced by a two-hit protocol and their impact on cognitive function in juvenile mice. Three-week-old male C57BL/6 mice received a high-fat diet (HFD) or control diet for 7 weeks, associated with two low doses of streptozotocin (STZ) or vehicle.

Effect of periodontal therapy on insulin resistance in adults with dysglycemia and periodontitis: a systematic review and meta-analysis.

Objectives: This systematic review and meta-analysis aimed to address whether non-surgical periodontal therapy (NSPT) can affect insulin resistance, estimated by the homeostasis model assessment (HOMA), in adults with prediabetes or type 2 diabetes mellitus and periodontitis.

Materials And Methods: Six electronic databases and the gray literature were systematically searched for interventional studies reporting NSPT effect on insulin resistance. Seven studies met the eligibility criteria to be synthesized in the qualitative analysis, six reporting change in HOMA-IR, three reporting change in HOMA-%S, and two in HOMA-β.

Thermogenic adipose tissue aging: Mechanisms and implications.

Adipose tissue undergoes significant anatomical and functional changes with aging, leading to an increased risk of metabolic diseases. Age-related changes in adipose tissue include overall defective adipogenesis, dysfunctional adipokine secretion, inflammation, and impaired ability to produce heat by nonshivering thermogenesis. Thermogenesis in adipose tissue is accomplished by brown and beige adipocytes, which also play a role in regulating energy homeostasis.

Lipids from gut microbiota: pursuing a personalized treatment.

The discovery of microbiome metabolites has enlivened the field of fecal transplantation for therapeutic purposes. However, the transfer of pathogenic living organisms was recently observed to limit its therapeutic potential by increasing the risk of infection. Lipids produced by gut microbiota enter the circulation and control many phenotypic changes associated with microbiota composition.

Selective modulator of nuclear receptor PPARγ with reduced adipogenic potential ameliorates experimental nephrotic syndrome.

Glomerular disease manifests as nephrotic syndrome (NS) with high proteinuria and comorbidities, and is frequently refractory to standard treatments. We hypothesized that a selective modulator of PPARγ, GQ-16, will provide therapeutic advantage over traditional PPARγ agonists for NS treatment. We demonstrate in a pre-clinical NS model that proteinuria is reduced with pioglitazone to 64%, and robustly with GQ-16 to 81% of nephrosis, comparable to controls.

Discovery of (E)-4-styrylphenoxy-propanamide: A dual PPARα/γ partial agonist that regulates high-density lipoprotein-cholesterol levels, modulates adipogenesis, and improves glucose tolerance in diet-induced obese mice.

Peroxisome proliferator-activated receptors are promising therapeutic targets for metabolic diseases, including obesity, diabetes, and dyslipidemia. This study describes the design, synthesis and pharmacological evaluation of stilbene-based compounds as dual PPARα/γ partial agonists with potency in the nanomolar range. In vitro and in vivo assays revealed that the lead compound (E)-4-styrylphenoxy-propanamide (5b) removed C-cholesterol from the foam cells through apolipoprotein A-I and High-Density Lipoprotein-2.

Liraglutide Activates Type 2 Deiodinase and Enhances β3-Adrenergic-Induced Thermogenesis in Mouse Adipose Tissue.

Aims: Liraglutide is a long-acting glucagon-like peptide 1 (GLP-1) receptor agonist used as an anti-hyperglycemic agent in type 2 diabetes treatment and recently approved for obesity management. Weight loss is attributed to appetite suppression, but therapy may also increase energy expenditure. To further investigate the effect of GLP-1 signaling in thermogenic fat, we assessed adipose tissue oxygen consumption and type 2 deiodinase (D2) activity in mice treated with liraglutide, both basally and after β3-adrenergic treatment.

The association between excess body weight at diagnosis and pediatric leukemia prognosis: A systematic review and meta-analysis.

Obesity affects the prognosis of several types of cancer. However, whether excess body weight is independently associated with adverse outcomes following initial pediatric acute leukemia (AL) treatment is still unclear. We conducted a systematic review and meta-analysis to investigate the impact of overweight/obesity at diagnosis on pediatric AL prognosis following initial treatment by performing an extensive database search up to January 22, 2021.

Obesity and endocrine-disrupting chemicals.

Obesity is now a worldwide pandemic. The usual explanation given for the prevalence of obesity is that it results from consumption of a calorie dense diet coupled with physical inactivity. However, this model inadequately explains rising obesity in adults and in children over the past few decades, indicating that other factors must be important contributors.

Predictors of sudomotor dysfunction in patients with type 1 diabetes without clinical evidence of peripheral neuropathy.

Aim: To investigate the frequency of foot sudomotor dysfunction determined by the electrochemical skin conductance test (ESC) and its independent predictors in individuals with type 1 diabetes mellitus (T1D) and no clinical evidence of diabetic peripheral neuropathy (DPN).

Methods: Adults with T1D for longer than 5 years and without DPN defined by the Michigan Neuropathy Screening Instrument and Neuropathy Disability Score were assessed for foot sudomotor dysfunction by ESC. Multivariate logistic regression analysis was used to examine the association between foot sudomotor dysfunction (ESC < 70 µS) and demographic, clinical, and biochemical variables.

Factors associated with overweight and abdominal obesity in Brazilian school-aged children: a comprehensive approach.

Objective We investigated the association between demographic, socio-economic, perinatal, parental and lifestyle-related factors with general and abdominal obesity among prepubertal children aged 6 to 8 years in a Southeastern city of Brazil. Subjects and methods A total of 486 children were randomly selected from public schools in the city of Patos de Minas, and examined to determine body mass index (BMI) and waist circumference (WC). Demographic, socio-economic, perinatal, parental and lifestyle-related data were obtained and assessed as independent risk factors for overweight/obesity and abdominal obesity, using multiple regression analysis.

Intrauterine Device Insertion during Cesarean Section in Women without Prenatal Contraception Counseling: Lessons from a Country with High Cesarean Rates.

Objective:  The moment of admission for delivery may be inappropriate for offering an intrauterine device (IUD) to women without prenatal contraception counseling. However, in countries with high cesarean rates and deficient prenatal contraception counseling, this strategy may reduce unexpected pregnancies and repeated cesarean sections.

Methods:  This was a prospective cohort study involving 100 women without prenatal contraception counseling.
