Human T-cell leukemia virus type 1 (HTLV-1) is associated with an increased risk of tuberculosis (TB). This study aimed to evaluate the performance of the QuantiFERON-TB Gold (QFT) test for the diagnosis of (MTB) infection in HTLV-1-infected individuals. HTLV-1-infected participants were divided into four groups: HTLV-1-infected individuals with a history of tuberculosis (HTLV/TB), individuals with positive HTLV and tuberculin skin tests (HTLV/TST+) or negative TST (HTLV/TST-), and HTLV-1-negative individuals with positive TST results (HN/TST+).

Candidiasis is an infectious disease caused by some fungi of the genus Candida. In Brazil, the incidence rate is higher than in European countries and the United States, and health problems occur mainly due to the virulence factors of the fungi, which have made treatment with commercial drugs difficult. Considering the context, plants rich in phenolic compounds, such as those of the genus Piper, have been studied due to their antimicrobial properties.

Introduction:  Erector spinae plane (ESP) blocks, thoracic epidural, and patient-controlled analgesia (PCA) have all been used for perioperative pain management in the Nuss procedure without a consensus on what modality produces the best outcomes. Intercostal nerve cryoablation (INC) is a relatively new modality that involves freezing the nerves to prevent pain during recovery. Our hypothesis is that using INC for the Nuss procedure will decrease opioid use, pain scores, and length of stay (LOS) but will increase cost compared with ESP block, thoracic epidural, and PCA.

This study investigated the Australian general public's views on trade-offs between reducing health inequalities and improving total health. It elicited relative equity weights, comparing inequalities in life expectancy at birth across three equity-relevant dimensions: income (comparing poorest versus richest fifth), ethnic (comparing Indigenous versus non-Indigenous), and geographic (comparing rural/remote versus major cities). A benefit trade-off exercise was administered via online survey to a sample of Australian adults (n = 3105) using quota sampling to ensure population representativeness across key demographic variables (age, gender, state of residence, household income and education level).

Recently, efforts have been made to address the environmental damage caused by fossil-fuel-based primary energy sources. Interest in efficient technologies for converting and storing energy using renewable sources, especially sunlight, has increased, with the aim of replicating the natural photosynthesis process. However, artificial photosynthesis faces challenges with unfavorable kinetics and thermodynamics, requiring the use of stable catalysts for the hydrogen evolution (HER) and oxygen evolution (OER) reactions to generate H and O, respectively.

Article Synopsis
  • Scabies and related bacterial skin infections are common in tropical and low-income areas, significantly raising healthcare costs and straining health systems.
  • The "Big SHIFT" trial in Fiji analyzed scabies and SSTIs from 2018 to 2019, aiming to estimate the healthcare costs associated with these conditions before a mass drug treatment campaign.
  • The study found that healthcare costs for scabies and SSTIs in Fiji totaled approximately $3 million annually, with an estimated cost of $3.3 per person, highlighting the economic impact and the potential benefits of prevention efforts.

Article Synopsis
  • - Brazil experienced significant COVID-19 impact, highlighted by high death tolls and four main peaks of cases, with the last two waves driven by the emergence of the Omicron variant and its sublineages BA.1, BA.2, BA.4, and BA.5.
  • - A study analyzed virus samples from 15 health units in Minas Gerais, revealing that BA.1 and BA.2 were most common in the third wave, while BA.4 and BA.5 dominated the fourth.
  • - Findings indicate that vaccination, especially booster doses, played a crucial role in reducing deaths, and the study confirmed the introduction of Omicron subvariants through multiple international cases with continued local transmission.

Brazil has a very large biological variety, which is an almost inexhaustible source of substances of pharmacological and biotechnological interest. Several studies have demonstrated the presence of bioactive peptides in insect hemolymph and their potential use as therapeutic agents. However, few data are available regarding molecules extracted from insects with anti-apoptotic action.

Pregnant women (PW) are at a higher risk of diseases and hospitalization from viral respiratory infections, particularly influenza and SARS-CoV-2, due to cardiopulmonary and immunological changes. This study assessed the impact of viral respiratory infections on PW hospitalized with severe acute respiratory infection (SARI) prior to the COVID-19 pandemic. It is a cross-sectional study with 42 PW and 85 non-pregnant women (NPW) admitted with SARI to two tertiary hospitals between January 2015 and December 2019.
