Article Synopsis
  • Tuberculosis (TB) is a major health issue for children and adolescents in Brazil, but research on treatment outcomes in this demographic is scarce, prompting the study of factors influencing these outcomes.
  • The study analyzed data from over 88,000 children and adolescents with TB from 2001 to 2022, identifying that 10.5% experienced poor treatment outcomes, mainly linked to HIV, substance use, and lack of supervised treatment.
  • Government cash transfer programs appeared to reduce the risk of death from TB, highlighting the importance of social support in improving treatment outcomes.

This study characterized the quality of primary care based on the responses of professionals and users, focusing on the type of physician - whether or not they were included in the More Doctors Program (PMM, acronym in Portuguese). A cross-sectional study was conducted applying the Quality and Strengthening of Primary Care Questionnaire to 149 physicians and 795 users in basic health units in Pernambuco State, Brazil, from February to November 2018. The present study used the concept of PMM provision which foresees the allocation of medical professionals to an areas of social vulnerability.

Toxoplasmosis is a parasitic disease caused by infection with Toxoplasma gondii, capable of infecting a wide range of hosts. The parasite exhibits a broad genetic diversity, necessitating genotypic characterization for genotype identification and associations with epidemiological information. Therefore, the Restriction Fragment Length Polymorphism (RFLP) technique is used for characterization.

Background: Skin injury affects the integrity of the skin structure and induces the wound healing process, which is defined by a well-coordinated series of cellular and molecular reactions that aim to recover or replace the injured tissue. Hydrogels are a group of promising biomaterials that are able to incorporate active ingredients for use as dressings. This study aimed to synthesize hydrogels with and without propolis extract and evaluate their physical characteristics and biological activities in vitro for potential use as active dressings in the treatment of skin lesions.

  • The study investigated the effects of ozone therapy on wound healing in the skin of rats, utilizing different treatment methods.
  • A total of 120 male rats were divided into five groups to receive varying treatments such as saline solution, sunflower oil, ozonated sunflower oil, and ozone bagging.
  • Results indicated that ozone bagging enhanced wound healing compared to other methods, and although ozone therapy was generally safe, certain treatments showed better efficacy at different time points.

The performance evaluation of services through instruments is relevant, as it can support thoughts, actions and political approaches to meet a social need. The objective of the article was to develop and validate the Quality and Strengthening of Primary Care Questionnaire (QSPC-Q) for professionals and users based on Starfield attributes and Donabedian pillars. A mixed sequential study was performed to develop the QSPC-Q.

Introduction: Appendectomy is the standard treatment for appendicitis, with the laparoscopic technique offering benefits like lower infection rates and quicker recovery. However, residents often have their first practical experience with the procedure on real patients, increasing surgical risks. In this context, medical simulation emerges as a crucial methodology, allowing professionals to experience a variety of scenarios while preventing harm to patients.

The multiplex molecular diagnostic assays described for severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), influenza A (IAV) and B (IBV) viruses have been mainly based on real-time reaction, which limits their access to many laboratories or diagnostic institutions. To contribute to available strategies and expand access to differential diagnosis, we describe an end-point multiplex RT-PCR targeting SARS-CoV-2, IAV and IBV with simultaneous endogenous control amplification. Initially, we looked for well-established primers sets for SARS-CoV-2, IAV, IBV and RNAse P whose amplicons could be distinguished on agarose gel.

Purpose: This study aims to conduct a thorough analysis, both quantitative and qualitative, of bibliometric parameters related to preemptive analgesia (PA) in oral surgical procedures (OSP).

Methods: Research trends on PA in OSP using ibuprofen were reviewed through bibliometric analysis of 68 journal articles published from 1991 to 2022 in the Web of Science database. Bibliometric indicators were applied to analyze the journal article data, including the annual distribution of publications and literature growth, document types, citation indicators to measure qualitative research performance, and keyword mapping to identify research trends.

Article Synopsis
  • Chronic Obstructive Pulmonary Disease (COPD) significantly affects global health, with factors such as smoking and immune cell profiles contributing to its severity; a deficiency in specific regulatory T cells can worsen respiratory issues.
  • Researchers employed Photobiomodulation (PBM) therapy to investigate its effects on immune response in a COPD mouse model by analyzing various immune cell types and cytokine production.
  • The findings indicated that PBM therapy alleviated COPD symptoms by reducing inflammatory immune cell counts, lowering pro-inflammatory cytokines like IFN-γ, and boosting the anti-inflammatory cytokine IL-10, suggesting a potential treatment avenue for COPD.

In this study, the oils of açaí, passion fruit, pequi, and guava were submitted to physicochemical analysis to investigate their potential application in the food industry. Gas chromatography associated with mass spectroscopy showed that oleic and linoleic acids are mainly responsible for the nutritional quality of açaí, passion fruit, pequi, and guava oils, which exhibited 46.71%, 38.

Papillomaviruses (PVs) have been identified in several animal species, including dogs (canine papillomaviruses, CPVs) and cattle (bovine papillomaviruses, BPVs). Although some BPVs may occasionally infect species other than cattle, to the best of our knowledge, BPVs have not been reported in dogs to date. Herein, we carried out a retrospective phylogenetic study of PVs circulating in dogs from southern Brazil between 2017 and 2022, also investigating possible mixed infections and spillover events.

Chagas disease (CD) is caused by the hemoflagellate protozoan Trypanosoma cruzi. The control of the infection depends of the innate and acquired immune response of host. Moreover, CD plays a significant role in the immune response, and, in this context, microalgae can be an interesting alternative due to its immunomodulatory and trypanocidal effects.
