Arthropod-borne viral diseases are acute febrile illnesses, sometimes with chronic effects, that can be debilitating and even fatal worldwide, affecting particularly vulnerable populations. Indigenous communities face not only the burden of these acute febrile illnesses, but also the cardiovascular complications that are worsened by urbanization. A cross-sectional study was conducted in an Indigenous population in the Northeast Region of Brazil to explore the association between arboviral infections (dengue, chikungunya, and Zika) and cardiac biomarkers, including cardiotrophin 1, growth differentiation factor 15, lactate dehydrogenase B, fatty-acid-binding protein 3, myoglobin, N-terminal pro-B-type natriuretic peptide, cardiac troponin I, big endothelin 1, and creatine kinase-MB, along with clinical and anthropometric factors.

Article Synopsis
  • * Among 94 patients, most were male and half had a history of hypertension; commonly observed kidney issues included collapsing glomerulopathy (CG), focal segmental glomerulosclerosis (FSGS), and thrombotic microangiopathy (TMA).
  • * Results indicated that FSGS and minimal change disease (MCD) were linked to better kidney survival compared to TMA, underscoring differences in kidney complications resulting from COVID-19 within this patient group.

Background: The prevalence of chronic kidney disease (CKD) is increasing worldwide, especially in developing countries, due to factors such as lifestyle changes and the rise of non-communicable diseases. Populations living in socioeconomically disadvantaged areas are subject to a higher burden of CKD. However, the burden of CKD on Brazilian Indigenous people, especially those undergoing an advanced urbanisation process, has not yet been described.

  • Dengue, a viral infection transmitted by Aedes aegypti mosquitoes, hit record levels in Brazil in early 2024 with over 1.3 million probable cases reported.
  • The study utilized time series and spatial analysis to identify trends and high-risk areas, revealing significant increases in cases, particularly in the Northeast and South regions.
  • A detailed analysis pinpointed risk areas, with the highest concentration of cases and relative risk found in Minas Gerais, highlighting the need for targeted public health interventions.

We aimed to investigate sex-related glycemic and cardiovascular responses after intensity- (moderate) and duration- (30 minutes) matched interval aerobic exercise (IAE) and continuous (CAE) aerobic exercise sessions in patients with type 1 diabetes mellitus (T1DM). A total of 19 volunteers (10 women) participated in 2 randomized and crossover sessions (1:1). Heart rate, systolic and diastolic blood pressure, double product, and blood glucose (BG) levels were measured before (PRE), immediately after (POST-0), and 20 minutes after (POST-20) each session.

This study focuses on the characterisation and incorporation of Moringa oleifera leaf powder (MOP) from Luanda (Angola) and its extract (MOE) in fortified chocolate mousse. Dark green (DG) leaves presented superior nutritional values compared to other leaves. DG contained a higher concentration of mineral salts (10 ± 1 mg/100 g of dry leaves), phenolic compounds (267 ± 4 mg GAE/g), vitamins (1.

TB is an infectious disease with a worldwide impact. TB is closely associated with social and housing conditions, exerting a significant impact on the prison population, which is particularly susceptible to the disease. Evidence suggests that the COVID-19 pandemic has exacerbated social vulnerability.

Background: Chronic kidney disease (CKD) is a prevalent disease worldwide, with increasing incidence particularly in low- and middle-income countries. Indigenous communities have poorer CKD outcomes due to limited access to healthcare. They are also experiencing a shift toward a sedentary lifestyle and urbanization-related dietary changes, increasing the risk of CKD-related risk factors.

Objective: The aim of this study was to investigate whether the degree of urbanization influences the prevalence of chronic kidney disease in Brazilian indigenous people.

Methods: This is a cross-sectional study conducted between 2016 and 2017 in northeastern Brazil and includes individuals aged between 30 and 70 years from two specific indigenous groups who volunteered to participate in the study: the Fulni-ô people (lowest degree of urbanization) and the Truká group (greater degree of urbanization). Cultural and geographical parameters were used to characterize and measure the magnitude of urbanization.

Issues pertaining to the organization and efficiency of the labor market and to the dynamics of employment and unemployment have always been at the forefront of the concerns of economists. Typically, such issues are approached through the analysis of the conflicting interests of a representative worker and of a representative firm, each of which intending to maximize the corresponding intertemporal objective function. Much of the research undertaken on this subject neglects the fact that each person is unique and endowed with different personality traits that influence their educational attainment, their ability to access jobs, their productivity while employed, and also their willingness to support, through social welfare mechanisms, those who become unemployed.

  • Many patients with chronic kidney disease on dialysis own smartphones, with 64% reporting ownership, but only a small fraction (3.1%) are aware of kidney-related apps.
  • Despite this, 59.3% believe that mobile applications could aid in managing their condition effectively.
  • The study highlights that smartphone ownership correlates with higher education and income levels, and is associated with better adherence to treatment regimes.

Lupus nephritis is one of the most serious and frequent manifestations of systemic lupus erythematosus. It usually presents in the first years of the disease, which suspicion should be raised in cases of elevated serum creatinine, presence of proteinuria above 500 mg/day or active urinary sediment, in the absence of other apparent causes such as urinary tract infection and use of nephrotoxic drugs. In most cases, it affects the glomerulus, and its presentation is rare in the form of isolated tubulo-interstitial disease.

Dengue fever, chikungunya, and zika are highly prevalent arboviruses transmitted by hematophagous arthropods, with a widely neglected impact in developing countries. These diseases cause acute illness in diverse populations, as well as potential cardiovascular complications. A systematic review was carried out to investigate the burden of cardiac involvement related to these arboviruses.

Titanium dioxide nanotubes (TiO2-nts) were incorporated into a glass ionomer cement (GIC) with improved mechanical properties and antibacterial activity. The aims of the present in vitro study were to define the elemental characterization, aluminum (Al) release rate, and initial working time for GIC reinforced with TiO2-nts, in an experimental caries model. TiO2-nts were incorporated into GIC powder components at 5% by weight, and compared with unblended GIC.

Surface hydroxylation has been extensively studied over the years for a variety of applications, and studies involving hydroxylation of different silica surfaces are still carried out due to the interesting properties obtained from those modified surfaces. Although a number of theoretical studies have been employed to evaluate details on the hydroxylation phenomenon on silica (SiO) surfaces, most of these studies are based on computationally expensive models commonly based on extended systems. In order to circumvent such an aspect, here we present a low-cost theoretical study on the SiO hydroxylation process aiming to evaluate aspects associated with water-SiO interaction.

  • Collapsing glomerulopathy (CG) is classified as a subtype of focal segmental glomerulosclerosis, marked by glomerulus collapse and increased podocyte activity.
  • Recent studies indicate a higher prevalence of CG in populations of African descent, highlighting significant health disparities.
  • Key risk factors for CG include genetic mutations and infections like HIV and COVID-19, leading to severe symptoms and poorer outcomes compared to other FSGS subtypes.

Objectives: To evaluate the influence of the composite resin translucency used in direct anatomic fiber posts on the bond strength (BS) and microhardness (VHN) of a luting agent into flared roots.

Materials And Methods: The root canals of 70 single-rooted premolars were endodontically treated and prepared to simulate an oversized root canal. Prior to post cementation, composite resins with varying translucency (high translucent, HT; medium translucent, MT; high opacity, HO) were placed around the fiber posts to create anatomic fiber posts.
