Introduction: Malnutrition remains common in adults over 60 years old. Although there are screening and diagnostic tools for malnutrition, there is no globally used approach to diagnosing malnutrition in older adults admitted to the hospital. In this study, we verified the agreement between the Global Leadership Initiative on Malnutrition (GLIM) and the Mini Nutritional Assessment (MNA) and the ability of the instruments to identify frailty and sarcopenia associated with malnutrition.

Fat is an essential component of meat which contributes to its sensory characteristics. Therefore, producing cultivated fat is essential to replicate the texture, flavor, and juiciness of conventional meat. One of the challenges in obtaining cultivated fat is that once adipocytes reach differentiation in culture, they tend to float.

The high-frequency generator is considered a collagen stimulator and skin revitalizer, however there are few studies exploring its effects in the field of rejuvenation and aesthetics. Thus, this study aimed to investigate the impact of high frequency generator therapy on facial aging. A total of 26 participants aged between 50 and 60 years were selected and received high frequency generator treatment for eight weeks.

Background: Procrastination is characterized by the deliberate postponement of assigned educational tasks and is correlated with low academic achievement and depression. Concern about procrastination is particularly high among medical students, as it has a strong association with aspects such as low self-efficacy, lack of organization, low intrinsic motivation, inefficient effort regulation and time management problems. On the other hand, it was found that students' use of study strategies is significantly related to better academic results.

Lung cancer is the leading cause of cancer-related death. The use of computational methods to quantify changes that are not perceptible to the human eye is increasing in digital pathology imaging and has quickly improved detection rates at a low cost. Therefore, the present study aims to use complex computational shape markers as tools for automated analysis of the spatial distribution of cells in microscopy images of squamous cell lung carcinoma (SqCC).

Article Synopsis
  • The share of solar power in Brazil's grid is growing, helping reduce greenhouse gas emissions and improve energy security.
  • A study evaluates climate models' ability to predict surface solar irradiance in Brazil, indicating most regions may see a 2% to 8% increase, while the South may experience a 3% decrease.
  • The findings suggest potential growth in photovoltaic energy production if supported by public policies, emphasizing the need for careful assessment of climate model uncertainty.

Objective: To evaluate the clinical and laboratory outcomes of patients with type 2 diabetes by comparing the no reuse or reuse of syringes and needles for insulin injection.

Research Design And Methods: Adults with type 2 diabetes who had reused syringes and needles at least three times were randomly instructed either to not reuse or to reuse insulin syringes and needles five times. The primary outcomes assessed were glycemic control, pain scores, and skin complications (ecchymosis, lipohypertrophy, nodules, infection) at baseline and 4, 8, and 12 weeks after the intervention.

Pathogenic SOX11 variants have been associated with intellectual developmental disorder with microcephaly, and with or without ocular malformations or hypogonadotropic hypogonadism (HH) (IDDMOH, OMIM # 615866). In this article, we report seven new patients with de novo SOX11 variants. Five of the variants are missense, one nonsense, and one whole-gene deletion, most of them are novel variants.

The prevalence of type 2 diabetes (T2D) poses a significant health challenge, yet the contribution of air pollutants to T2D epidemics remains under-studied. Several studies demonstrated a correlation between exposure to volatile organic compounds (VOCs) in indoor/outdoor environments and T2D. Here, we conducted the first meta-analysis, establishing a robust association between exposure to benzene, a prevalent airborne VOC, and insulin resistance in humans across all ages.

Article Synopsis
  • Existing leishmaniasis treatments have limitations and side effects, prompting the exploration of new alternatives like the lectin DVL from Dioclea violacea seeds.
  • DVL showed significant leishmanicidal effects against Leishmania infantum in vitro, inducing reactive oxygen species and damaging the parasite's membrane, with an effective concentration of 49.37 μg/mL.
  • DVL enhanced the effectiveness of traditional drugs like amphotericin B and glucantime, reduced macrophage infection rates, and exhibited no toxicity in healthy cells, indicating its potential as a treatment for visceral leishmaniasis.

Article Synopsis
  • Antiretroviral treatments have improved survival rates for People Living with HIV/AIDS (PLWHA), but they've also led to an increased incidence of sarcopenia among an aging population, prompting the need for local studies due to varying prevalence results.
  • A cross-sectional study involving 218 PLWHA aged 40 and older utilized the EWGSOP2 criteria to assess sarcopenia prevalence, muscle mass, strength, and function through various tests, finding an 8.7% prevalence rate.
  • The study concluded that longer duration of HIV infection and illicit drug use were associated with a higher likelihood of developing sarcopenia, although overall prevalence was relatively low.

Two new heptapeptides, [1-7-NαC]-crocaorbs A1 (1) and A2 (2), were isolated from the latex of Croton campanulatus. Their structures were determined using NMR spectroscopic techniques, ESI-HRMS data, Marfey's method, and further refined using molecular dynamics with simulated annealing (MD/SA). Molecular dynamics calculations of peptides 1 and 2 demonstrated greater stability in simulations using a biological solvent compared to those using DMSO.

Early life stress may lead to lifelong impairments in psychophysiological functions, including emotional and reward systems. Unpredicted decrease in reward magnitude generates a negative emotional state (frustration) that may be involved with susceptibility to psychiatric disorders. We evaluated, in adolescents and adult rats of both sexes, whether maternal separation (MS) alters the ability to cope with an unexpected reduction of reward later in life.

Our previous work demonstrated the presence of lead (Pb) and cadmium (Cd) contamination in cow milk (CM) and soy beverages (SBs) in Portugal. These metals share carcinogenic mechanisms, suggesting at least additive effects. Our goals were to assess carcinogenic risks from Pb and Cd intake detected in various CM and SB brands on the Portuguese market and to determine the relative contributions of Pb and Cd.

Low serum 25(OH)D levels (< 30 nmol/L) have been associated with increased depressive symptom scores over time, and it is believed that functionality may play a mediating role in the relationship between 25(OH)D and depressive symptoms. To comprehend the association between these factors could have significant implications for public health policy. The aim of this study was to verify the association between simultaneous vitamin D insufficiency and depressive symptoms, and functional disability in community-dwelling older adults.

Objective: To describe the feeding characteristics and growth of children with prenatal exposure to Zika virus (ZIKV) from birth to 48 months.

Design: Using data from the prospective Microcephaly Epidemic Research Group Pediatric Cohort (MERG-PC), children without microcephaly born to mothers with evidence of ZIKV infection during pregnancy (ZIKV-exposed children without microcephaly) and children with Zika-related microcephaly were compared using repeated cross-sectional analyses within the following age strata: birth; 1 to 12; 13 to 24; 25 to 36; and 37 to 48 months. The groups were compared in relation to prematurity, birth weight, breastfeeding, alternative feeding routes, dysphagia and anthropometric profiles based on the World Health Organization Anthro z-scores (weight-length/height, weight-age, length/height-age and BMI-age).
