Association between vitamin D deficiency and lipid profiles in overweight and obese adults: a systematic review and meta-analysis.

Objective: The association between vitamin D deficiency and lipid profiles in adults with overweight or obesity remains unclear and inconsistent. The aim of our study was to determine the relationship between lipid profiles and vitamin D deficiency in the overweight and obese adults.

Methods: Four databases, including PubMed, the Web of Science, EMBASE and the Cochrane Library, were used to identify all studies on vitamin D status and lipid levels, including the serum levels of triglycerides (TGs), total cholesterol (TC), low-density lipoprotein cholesterol (LDL), and high-density lipoprotein cholesterol (HDL).

Bariatric surgery and COVID-19 outcomes: a systematic review and meta-analysis.

Background: Obesity and its associated complications have a negative impact on human health. Metabolic and bariatric surgery (MBS) ameliorates a series of clinical manifestations associated with obesity. However, the overall efficacy of MBS on COVID-19 outcomes remains unclear.

Serum levels of interleukin-18 in diabetic retinopathy patients: A meta-analysis.

Purpose: To assess the relationship between plasma interleukin-18 (IL-18) levels and the risk of diabetic retinopathy (DR).

Materials And Methods: PubMed, Embase, Web of science, and Cochrane were reviewed systemically from inception to August 2022. Searches were performed using a combined term that included all spellings of "diabetic retinopathy," and "interleukin-18".

The Value of Visfatin in the Prediction of Metabolic Syndrome: A Systematic Review and Meta-Analysis.

Various studies have shown that visfatin may be connected to metabolic syndrome (MS). However, epidemiological studies yielded conflicting outcomes. The purpose of this article was to highlight the relationship between the plasma visfatin level and MS risk by conducting a meta-analysis of available literature.

Associations between COVID-19 infection and sex steroid hormones.

Aims: Coronavirus disease 2019 (COVID-19) is caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and within a few months of the first outbreak, it was declared a global pandemic by the WHO. The lethal virus SARS-CoV-2 is transmitted through respiratory droplets and enters host cells through angiotensin-converting enzyme 2 (ACE-2) receptors. ACE-2 receptors are highly expressed in many tissues, including testes.

Bariatric surgery and secondary hyperparathyroidism: a meta-analysis.

Background: Obesity increases the risk of obesity-related medical problems. Weight loss after metabolic and bariatric surgery (MBS) has been well studied. However, the effects of MBS on parathyroid function remain unclear.

Bariatric Surgery and the Risk of Cerebrovascular Events: a Meta-analysis of 17 Studies Including 3,124,063 Subjects.

Purpose: To perform a meta-analysis of the literature to evaluate the prevalence of cerebrovascular comorbidities between patients undergoing bariatric surgery and those not undergoing bariatric surgery.

Materials And Methods: Studies about the risk of cerebrovascular disease both before and after bariatric surgery were systematically explored in multiple electronic databases, including PubMed, Web of Science, Cochrane Library, and Embase, from the time of database construction to May 2022.

Results: Seventeen studies with 3,124,063 patients were finally included in the meta-analysis.

Surgery After Ultrasound-Guided Radiofrequency Ablation for Papillary Thyroid Carcinoma in 21 Patients: A Retrospective Study from a Single Center in China.

BACKGROUND Radiofrequency ablation (RFA) is used to treat various cancers, but its use in thyroid cancer remains controversial. The aim of this study was to investigate surgical findings after RFA for papillary thyroid cancer (PTC). MATERIAL AND METHODS The study included 21 patients (average age 44.

Metformin plays a dual role in MIN6 pancreatic β cell function through AMPK-dependent autophagy.

Metformin improves insulin sensitivity in insulin sensitive tissues such as liver, muscle and fat. However, the functional roles and the underlying mechanism of metformin action in pancreatic β cells remain elusive. Here we show that, under normal growth condition, metformin suppresses MIN6 β cell proliferation and promotes apoptosis via an AMPK-dependent and autophagy-mediated mechanism.
