GFRAL-expressing neurons actuate aversion and nausea, are targets for obesity treatment, and may mediate metformin effects by long-term GDF15-GFRAL agonism. Whether GFRAL+ neurons acutely regulate glucose and energy homeostasis is, however, underexplored. Here, we report that cell-specific activation of GFRAL+ neurons using a variety of techniques causes a torpor-like state, including hypothermia, the release of stress hormones, a shift from glucose to lipid oxidation, and impaired insulin sensitivity, glucose tolerance, and skeletal muscle glucose uptake but augmented glucose uptake in visceral fat...

BACKGROUND: Metformin is commonly prescribed to treat polycystic ovary syndrome (PCOS) patients, but in some cases, it may not be effective even at high doses or may cause intolerable side effects. Therefore, recent studies have examined the impact of combining metformin with other antidiabetic medications. METHODS: A systematic search was performed in Scopus, PubMed, Web of Science, and Embase up to 30 June 2023. All interventional studies that assessed the efficacy of different antidiabetic agents were included...

Polycystic ovary syndrome (PCOS) is the leading cause of endocrine disorders among females of reproductive age and is linked with autoimmune disorders. PCOS has been associated with autoantibodies such as antinuclear antibody (ANA), anti-thyroid, and anti-Smith (anti-SM). Young patients with PCOS and systemic lupus erythematosus (SLE) have up to a 10-fold increase in stroke. We present a case of a patient with a history of PCOS (on metformin), hypothyroidism, and pulmonary embolism who presented to the emergency room with acute left-sided weakness...

INTRODUCTION: Tirzepatide is a novel glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist. In the SURPASS-AP-Combo trial, once-weekly tirzepatide was associated with improved glycemic control and weight loss versus insulin glargine and was generally well tolerated in an Asia-Pacific, predominately Chinese, population with type 2 diabetes (T2D). This post hoc subgroup analysis of SURPASS-AP-Combo assessed the potential influence of patient baseline characteristics on the efficacy and safety of tirzepatide...

INTRODUCTION: Insulin is the first-line pharmacologic therapy for women with diabetes in pregnancy. However, conducting well-designed randomized clinical trials (RCTs) and achieving recommended glycemic targets remains a challenge for this unique population. This systematic literature review (SLR) aimed to understand the evidence for insulin use in pregnancy and the outcome metrics most often used to characterize its effect on glycemic, maternal and fetal outcomes in gestational diabetes mellitus (GDM) and in pregnant women with diabetes...

INTRODUCTION: Prediabetes is a state of subclinical glycemic impairment, bridging normal glucose tolerance and diabetes. Globally, over 30% of individuals exhibit prediabetic conditions, with a significant proportion progressing to diabetes. Prediabetes augments risks of various diseases including cardiovascular and kidney disease. While interventions like lifestyle changes have shown promise in diabetes prevention, their long-term sustainability is challenging. Alternative pharmacological treatments, such as acarbose and metformin, have demonstrated efficacy in certain populations...

OBJECTIVE: To investigate the target and mechanism of action of Bushen Huoxue Recipe (BSHX) for the treatment of infertility in polycystic ovary syndrome (PCOS), to provide a basis for the development and clinical application of herbal compounds. METHODS: Prediction and validation of active ingredients and targets of BSHX for the treatment of PCOS by using network pharmacology-molecular docking technology. In an animal experiment, the rats were randomly divided into four groups (control group, model group, BSHX group, metformin group, n  = 16 in each group), and letrozole combined with high-fat emulsion gavage was used to establish a PCOS rat model...

BACKGROUND: Heterozygous insulin receptor mutations (INSR) are associated with insulin resistance, hyperglycaemia and hyperinsulinaemic hypoglycaemia in addition to hyperandrogenism and oligomenorrhoea in women. Numerous autosomal dominant heterozygous mutations involving the INSR β-subunit tyrosine kinase domain resulting in type A insulin resistance have been previously described. We describe the phenotype, obstetric management and neonatal outcomes in a woman with type A insulin resistance caused by a mutation in the β-subunit of the INSR...

OBJECTIVE: SGLT-2i are increasingly recognized for their benefits in patients with cardiometabolic risk factors. Additionally, emerging evidence suggests potential applications in acute illnesses, including COVID-19. This systematic review aims to evaluate the effects of SGLT-2i in patients facing acute illness, particularly focusing on SARS-CoV-2 infection. METHODS: Following PRISMA guidelines, a systematic search of PubMed, Scopus, medRxiv, Research Square, and Google Scholar identified 22 studies meeting inclusion criteria, including randomized controlled trials and observational studies...

Polycystic ovary syndrome is a common reproductive endocrine condition that affects women of fertile age and is characterized by three main features, including hyperandrogenism, chronic anovulation, and polycystic ovaries. In addition, half of women with polycystic ovary syndrome have insulin resistance, and obesity or overweight, type 2 diabetes, hypertension, and hyperlipidemia are the most common metabolic abnormalities affecting (30%) women with polycystic ovary syndrome. Weight loss is regarded as the first-line treatment as it can potentially improve polycystic ovary syndrome parameters (androgen levels, menstrual cyclicity, lipid and glucose metabolism)...

BACKGROUND: Polycystic ovary syndrome (PCOS) is a gynecological endocrine disorder characterized by ovulatory disorders, hyperandrogenemia, and polycystic changes in the ovaries. FDX1 is a ferredoxin-reducing protein on human mitochondria that plays an important role in steroid anabolism. Liraglutide, a glucagon-like peptide-1 receptor agonist (GLP-1RA), has recently emerged as a potential therapeutic agent for PCOS. Recent studies have suggested that FDX1 may be associated with the development of PCOS...

Polycystic ovary syndrome (PCOS), as an endocrine and metabolic disorder, affects approximately 6% -20% of women of childbearing age. This study aims to assess the therapeutic effects of Metformin combined with vitamin D in PCOS patients. Eight databases were searched to obtain randomized controlled trials, both domestically and internationally, on the effects of Metformin combined with vitamin D in patients with PCOS. Data analysis was performed using RevMan 5.3 software. Nine studies were ultimately included in this meta-analysis...

BACKGROUND: Compared to Immediate-Release (IR) metformin, Extended-Release (ER) metformin reduces side effects and pill burden while improving adherence; however, there is little real-life data on patient satisfaction with this innovative formulation to guide physicians toward a more holistic approach. OBJECTIVE: Our goal is to train general practitioners on holistic patient management, with the aim of increasing patient satisfaction and treatment adherence, reducing side effects, and improving quality of life in patients with poor tolerance to metformin-IR...

Pasireotide is a somatostatin analogue for the treatment of acromegaly, a chronic condition caused by excess growth hormone. Despite the therapeutic benefits of pasireotide as a second-line treatment for inadequately controlled acromegaly, a major concern is its hyperglycemic side-effect. Here, we provide guidance on how to select appropriate patients with acromegaly for treatment with pasireotide. We summarize baseline characteristics of patients at high risk for pasireotide-associated hyperglycemia and recommend a monitoring strategy based on the risk profile...

BACKGROUND: Polycystic ovary syndrome (PCOS) is a multisystem reproductive-metabolic disorder and the most common endocrine cause of infertility. The objective of our study was to determine the influence of myo-inositol (MI) on insulin resistance (IR), menstrual cycle regularity, and hyperandrogenism in women suffering from PCOS with normal BMI and diagnosed IR. METHODS: We performed a prospective randomized controlled trial (RCT) that included 60 participants with PCOS who had IR and a normal BMI...

Pharmaceuticals and the accumulation of their biotransformation products are becoming the most common emerging contaminants of concern in environmental water ecosystems. Accumulation of metformin and its biotransformation product "guanylurea" are posing an increasing concern due to their low biodegradability under natural attenuated conditions. Therefore, in this study, we reviewed the unavoidable function of metformin in human body and the route of its release in different water ecosystems. In addition, metformin and its biotransformation product guanylurea in aquatic environments caused certain toxic effects on aquatic organisms, which include, neurotoxicity, endocrine disruption, production of ROS, and acetylcholinesterase disturbance...

CONTEXT: Fibroblast growth factor 21 (FGF21) and growth differentiation factor 15 (GDF15) are increased in type 2 diabetes and are potential regulators of metabolism. The effect of changes in caloric intake and macronutrient composition on their circulating levels in patients with type 2 diabetes are unknown. OBJECTIVE: To explore the effects of a carbohydrate-reduced high-protein diet with and without a clinically significant weight loss on circulating levels of FGF21 and GDF15 in patients with type 2 diabetes...

BACKGROUND: The increase in portal insulin levels has been shown to upregulate growth hormone receptor expression in the liver, leading to increased insulin-like growth hormone- 1 levels. Metformin inhibits hepatic gluconeogenesis and reduces fasting insulin. OBJECTIVE: We evaluated the effect of metformin treatment in patients with acromegaly on growth hormone, insulin-like growth hormone-1, and pituitary adenoma size. METHODS: Patients who were followed up with the diagnosis of acromegaly in Istanbul University- Cerrahpaşa, Cerrahpaşa Medical Faculty were evaluated...

BACKGROUND/AIM: Managing reactive hypoglycaemia (RH) poses challenges due to limited and often ineffective treatment options. We report a case series and draw on this to propose a stepwise treatment approach consisting of lifestyle modifications, metformin, GLP-1 analogues, and the use of flash glucose monitoring technology. METHOD: A retrospective review was conducted to analyse the management of 11 cases presenting with recurrent RH symptoms. RESULT: Two patients experienced successful resolution of symptoms through lifestyle modifications...
