Sex differences in long-term fear and anxiety-like responses to deep brain stimulation in a preclinical model of PTSD.

Deep brain stimulation (DBS) is currently being investigated in patients and preclinical models of posttraumatic stress disorder (PTSD), but differences in behaviour according to sex remain elusive. We exposed female and male rats to fear conditioning and extinction. Thereafter, animals were treated with ventromedial prefrontal cortex DBS, followed by a battery of tests to measure fear and anxiety-like behaviour.

Relationship Between the Single Nucleotide Polymorphism A35C in the Cu/Zn-Superoxide Dismutase-1 Gene and Glycemic Control in Individuals with Type 2 Diabetes Mellitus.

Hyperglycemia in type 2 diabetes mellitus (T2DM) increases oxidative stress. Furthermore, the presence of the single nucleotide polymorphism A35C (SNP A35C) in Cu/Zn-superoxide dismutase1 (SOD1) gene is closely related to this increase in oxidative stress and the development and progression of T2DM and its complications. This study aimed to evaluate the association between SNP A35C (rs2234694) genotypes and glycemic control in T2DM individuals.

Nutrigenetics and Nutritional Strategies in Systemic Arterial Hypertension: Evidence From a Scoping Review.

Nutrition and genetics have individual roles in systemic arterial hypertension (SAH); however, they can interact, influencing the regulation of blood pressure (BP) levels. The aim of this study was to evaluate the available evidence regarding gene-nutrient interactions in modulating BP levels in adults with SAH. The review followed the recommendations of the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

Association between circulating micro-ribonucleic acids and metabolic syndrome in older adults from a population-based study.

Epigenetic causes are risk factors in NCD development since studies indicate that the expression of micro-ribonucleic acids (miRs) is altered under different clinical conditions. This study aimed to analyze the expression profile of circulating miRs and investigate their association with biomarkers of cardiometabolic risk in older adults living in São Paulo municipality, Brazil.

Measurements included serum 25-hydroxyvitamin D (25[OH]D), glucose, insulin, total cholesterol, LDL-c, HDL-c, triacylglycerols, blood pressure, body mass index, %body fat, and waist circumference.

Supplementation of vitamin D isolated or calcium-associated with bone remodeling and fracture risk in postmenopausal women without osteoporosis: A systematic review of randomized clinical trials.

Menopause and vitamin D deficiency increase bone reabsorption and bone fracture risk in women in postmenopause, and vitamin D supplementation may improve bone health and decrease bone fracture risk. This study aims to discuss the effect of vitamin D supplementation, isolated or calcium-associated, on remodeling and fracture risk bone in women in postmenopause without osteoporosis. This study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO database registration: CRD42022359796).

Circulating MiRNAs Are Associated With Low-grade Systemic Inflammation and Leptin Levels in Older Adults.

Inflammaging refers to the low-grade systemic inflammation that occurs with aging present in chronic non-communicable diseases. MicroRNAs (miRNAs) are potential biomarkers for these diseases in older adults. This study aimed to assess the expression of 21 circulating miRNAs and their associations with inflammatory biomarkers in older adults.

Magnesium Status and Dietary Patterns Associated with Glycemic Control in Individuals with Type 2 Diabetes Mellitus.

Hypomagnesemia and unhealthy eating patterns are associated with poor glycemic control in individuals with type 2 diabetes mellitus (T2DM). This study aimed to associate magnesium status and dietary patterns with glycemic control in T2DM individuals. This cross-sectional study included 147 individuals with T2DM, aged between 19 and 59 years, of both sexes, residents in Sergipe/Brazil.

Circulating microRNAs Showed Specific Responses according to Metabolic Syndrome Components and Sex of Adults from a Population-Based Study.

MicroRNAs (miRNAs) regulate several metabolic pathways and are potential biomarkers for early risk prediction of metabolic syndrome (MetS). Our aim was to evaluate the levels of 21 miRNAs in plasma according to MetS components and sex in adults. We employed a cross-sectional study of 192 adults aged 20 to 59 years old from the 2015 Health Survey of São Paulo with Focus in Nutrition.

Circulating microRNA Related to Cardiometabolic Risk Factors for Metabolic Syndrome: A Systematic Review.

MicroRNA regulates multiple pathways in inflammatory response, adipogenesis, and glucose and lipid metabolism, which are involved in metabolic syndrome (MetS). Thus, this systematic review aimed at synthesizing the evidence on the relationships between circulating microRNA and risk factors for MetS. The systematic review was registered in the PROSPERO database (CRD42020168100) and included 24 case-control studies evaluating microRNA expression in serum/plasma of individuals ≥5 years old.

Relationship Between the Single Nucleotide Polymorphism rs11558471 in the SLC30A8/ZnT8 Gene and Cardiometabolic Markers in Postmenopausal Women.

Postmenopausal women have more risk factors for metabolic syndrome, and genetic alterations in SLC30A8 (zinc transporter 8 [ZnT8]) are directly related to these factors. Our aim was to assess the relationship of the single nucleotide polymorphism (SNP) rs11558471 in the SLC30A8/ZnT8 gene with cardiometabolic markers in postmenopausal women. This cross-sectional study included 53 postmenopausal women divided into two groups according to the SNP genotype (AG + GG [n = 25] and AA [n = 28]).
