Background: Normal-weight obesity (NWO) is characterized by normal body mass index (BMI) but high body fat percentage (%BF) that increases the risks of cardiometabolic comorbidities. Accurate assessment and interpretation of body composition data are necessary to reduce these risks.

Objectives: To compare the cardiometabolic profile of individuals with NWO and normal %BF and evaluate the associated risk factors.

Article Synopsis
  • Fe-deficiency anaemia is a significant health issue for children under 5, and the matriptase-2 gene may influence iron levels and anaemia in different populations.
  • This study analyzed 163 Brazilian children aged 6-42 months to explore the connection between the rs855791 SNP and indicators of iron deficiency and anaemia.
  • Findings revealed that the T allele of rs855791 was linked to a higher risk of anaemia (4.49 times) and iron deficiency, with increasing doses contributing to lower blood cell volume and hemoglobin levels.

The expansion of bean genome technologies has prompted new perspectives on generating resources and knowledge essential to research and implementing biotechnological tools for the practical operations of plant breeding programs. This study aimed to resequence the entire genome (whole genome sequencing-WGS) of 40 bean genotypes selected based on their significance in breeding programs worldwide, with the objective of generating an extensive database for the identification of single nucleotide polymorphisms (SNPs). Over 6 million SNPs were identified, distributed across the 11 bean chromosomes.

The normal-weight obesity (NWO) is highly associated with an increased risk for chronic non-communicable diseases and intricately linked to diet quality. Therefore, we assessed the consumption of ultra-processed and non-ultraprocessed foods of 224 Brazilian adults with NWO ( 159) and without NWO ( 65, non-NWO) in a cross-sectional study. For that, three dietary recalls were applied and categorised according to the NOVA classification.

Introduction: Simulation is a promising strategy in health education, with evidence of importance for learning, but the available systematic reviews are still inconclusive about the effect of the strategy on stress, anxiety, and self-confidence of nursing students, which impact the adherence to and sustainment of this strategy. Thus, better evidence is needed of the impact of simulation on these competences, essential for health professional education.

Objective: To evaluate the effect of simulation-based experiences on stress, anxiety, self-confidence and learning of undergraduate nursing students compared to conventional teaching strategies or no intervention.

MicroRNAs (miRNAs) are important epigenetic regulators in head and neck squamous cell carcinoma (HNSCC), with miR-31 being considered an oncomir and miR-375, a tumor suppressor miR, which are up- and down-regulated in HNSCC, respectively. Nutrients are known to influence miRNA expression; however, this association is poorly explored in HNSCC. This work aimed to identify associations between dietary intake and the expression of miR-31 and miR-375 in patients newly diagnosed with HNSCC.

Article Synopsis
  • The study aimed to create genetic scores based on specific SNPs tied to lipid metabolism and assess their ability to predict lipid profile issues in adolescents.
  • Researchers evaluated 113 Brazilian adolescents with cardiovascular risk factors using a scoring system that measured the presence of risk alleles, resulting in scores from 0 to 10.
  • The findings showed that higher genetic scores correlated with negative changes in lipid biomarkers, indicating potential for these scores to estimate lipid profile disturbances among young individuals.

Article Synopsis
  • A study examined the effectiveness of using multiple micronutrient powder (MNP) versus standard drug supplementation in preventing and treating iron deficiency and anemia in children aged six to 42 months.
  • Results showed that MNP significantly reduced the prevalence of anemia from 13.58% to 1.85% and iron deficiency from 21.74% to 7.89%.
  • It was concluded that while MNP was effective for prevention, an additional dose of ferrous sulfate was necessary for treating anemic children.

Sporotrichosis is a subcutaneous mycosis of humans and other mammals, caused by dimorphic species of the genus Sporothrix. In Brazil, human disease is broadly linked to transmission by infected cats and is mainly caused by Sporothrix brasiliensis, Sporothrix schenckii and Sporothrix globosa. In this study, we used a nanoscale liquid chromatography coupled with tandem mass spectrometry approach to provide the yeast proteomic profiles of S.

Article Synopsis
  • RNA-Seq was used to analyze genes involved in drought response in leaf and root tissues from both drought-susceptible and drought-tolerant genotypes, identifying 54,750 transcripts from 28,590 genes, including 1,648 novel high-fidelity entries.
  • A total of 1,239 differentially expressed genes were found, predominantly in drought-tolerant genotypes, focusing on oxidative stress, response to stimuli, and kinase activity, indicating a proactive response to stress.
  • The study validated 88.64% of these genes using qPCR, identified a large number of genetic variants, and contributed data to the NCBI database, enhancing understanding of drought tolerance mechanisms in beans.

Objectives: Beet leaves and stalks are rich in polyphenols; however, their effect on risk factors for cardiovascular disease in humans, to our knowledge, has not yet been investigated. The aim of this study was to analyze the acute effect of beet leaves and stalk juice, containing different concentrations of polyphenols, on lipemia, glycemic control, nitric oxide concentration, and blood pressure in patients with dyslipidemia after a high-fat meal.

Methods: In a randomized double-blind, placebo-controlled, crossover pilot study, patients 20 to 59 y of age with dyslipidemia were fed a single high-fat meal supplemented with either a placebo or one of two organic beet leaves and stalk juices rich in polyphenols (32 or 77.

Diabetic patients often develop Diabetic Nephropathy (DN) despite severe long-lasting hyperglycemia, while others develop DN even under intensive insulin therapy. This indicates that factors other than chronic hyperglycemia may also contribute to the susceptibility to the development of DN. The purpose of this case-control study was to investigate the possible role of GSTM1 and GSTT1 deletion polymorphisms, and Single Nucleotide Polymorphism (SNP), GSTP1 313 A > G (Ile105Val), in DN susceptibility.

Background & Aims: Both green tea and metformin are used as adjuvants to treat and prevent complications associated with obesity; however, studies comparing their action and interaction in non-diabetic overweight women have not been reported. Thus, the current study evaluated the effects of green tea extract and metformin, both individually and in combination, on type 2 diabetes risk factors in non-diabetic overweight women.

Methods: A total of 120 overweight women were randomly assigned in a double-blind manner to 1 of 4 groups, as follows: control (n = 29; 1 g of cellulose), green tea (n = 32; 1 g of dry green tea extract), metformin (n = 28; 1 g of metformin), and green tea + metformin (n = 31; 1 g of dry green tea extract + 1 g of metformin).

The genus Paracoccidioides comprises a complex of phylogenetic species of dimorphic pathogenic fungi, the etiologic agents of paracoccidioidomycosis (PCM), a disease confined to Latin America and of marked relevance in its endemic areas due to its high frequency and severity. The members of the Paracoccidioides genus are distributed in distinct phylogenetic species (S1, PS2, PS3 and 01-like) that potentially differ in their biochemical and molecular characteristics. In this work, we performed the proteomic characterization of different members of the genus Paracoccidioides.
