Immunocompromised individuals were considered high-risk for severe disease due to SARS COV-2 infection. This study aimed to describe the safety of two doses of COVID-19 adsorbed inactivated vaccine (CoronaVac; Sinovac/Butantan), followed by additional doses of mRNA BNT162b2 (Pfizer/BioNTech) in immunocompromised (IC) adults, compared to immunocompetent/healthy (H) individuals. This phase 4, multicenter, open label study included solid organ transplant and hematopoietic stem cell transplant recipients, cancer patients and people with inborn errors of immunity with defects in antibody production, rheumatic, end-stage chronic kidney or liver disease, who were enrolled in the IC group.

Biofloc technology is an aquaculture production system that has gained popularity with tilapia production. Probiotics provide benefits for the host and/or aquatic environments by both regulating and modulating microbial communities and their metabolites. When a probiotic feed is combined with a biofloc system, the production amount may be improved through better fish growth, disease resistance, and/or improved water quality by reducing organic matter and stabilizing metrics such as pH and components of the nitrogen cycle.

Carbon dots in biosensing have advanced significantly, adding improvements to different detection techniques. In this study, an amperometric immunosensor for Salmonella Thyphimurium was designed using antibodies labeled with carbon dots (Cdots) from pequi almond (Caryocar brasiliensis). Cdots were synthesized by pyrolysis and characterized by FTIR, UV/fluorescence, electrochemistry, zeta potential, and transmission electron microscopy (TEM).

Background: Non-anaemic iron deficiency is highly prevalent in people living with chronic kidney disease (CKD) but is underdiagnosed and undertreated, especially in earlier stages of CKD. A multicentre trial assessing the effect of intravenous iron supplementation in iron-deficiency but not anaemic people with CKD included a qualitative sub-study that aimed to explore the patient experience and psychosocial impact of living with CKD and iron deficiency, and the experience of the therapeutic intervention (intravenous iron and exercise).

Methods: Semi-structured interviews were conducted with 23 trial participants blinded to treatment.

The objectives of the study were to: 1) Describe characteristics and lifestyle factors of individuals who have achieved type 2 diabetes (T2D) remission (sub-diabetes glucose levels without glucose-lowering medications for ≥3 months) through changes to diet and exercise behaviour in real-world settings; 2) Investigate continuous glucose monitoring (CGM) profiles of these individuals and explore how dietary pattern may influence glucose regulation metrics. This cross-sectional study recruited individuals living with T2D who achieved remission via changes to diet or exercise behaviours. Various questionnaires were used to assess overall health and participants wore a blinded CGM for 14 days to assess glucose profiles and filled out three-day food records.

People with type 2 diabetes (T2D) have a greater risk of developing neurodegenerative diseases, like Alzheimer's disease, in later life. Exogenous ketone supplements containing the ketone body β-hydroxybutyrate (β-OHB) may be a strategy to protect the brain as β-OHB can support cerebral metabolism and promote neuronal plasticity via expression of brain-derived neurotrophic factor (BDNF). Parallel human (ClinicalTrials.

Prior research suggests metformin has anti-cancer effects, yet data are limited. We examined the association between diabetes treatment (metformin versus sulfonylurea) and risk of incident diabetes-related and non- diabetes-related cancers in US veterans. This retrospective cohort study included US veterans, without cancer, aged ≥ 55 years, who were new users of metformin or sulfonylureas for diabetes between 2001 to 2012.

A double-blind, randomized, and controlled clinical trial with therapeutic intervention was performed at a university hospital in Rio de Janeiro to evaluate whether the addition of Hayne oleoresin to a carboxypolymethylene hydrogel is more effective in skin tear healing than standard treatment. The sample consisted of 84 patients, predominantly men, with a mean age of 67.37 years.

Many cancer patients have their main tumors surgically removed with the goal of curing them, or as part of palliative care. When a patient receives general anesthesia, the side effects of the administered chemotherapy regimens must be considered, especially those that may have significant repercussions during anesthetic care. The aim of this study is to review the existing literature to identify adverse effects of chemotherapy and known interactions between chemotherapy and anesthetic drugs, analyze the mechanisms underlying these interactions, and discuss relevant clinical implications.

Background: Ureteral stents are one of the most used devices in Urology, allowing drainage of the upper urinary system, and can be used either in elective or emergency procedures. However, as a foreign body inside the urinary system, they are subject to encrustation. Encrustation is one of the burdens seen with double-J stents and, to date, there is no consensus about its best management.

Purpose: To verify the number of patients with COPD responders to two different home-based rehabilitation programs.

Methods: This was a blinded, randomized, and controlled clinical trial. The six-minute step test (6MST), one-minute sit-stand test (1-MSTST), six-minute walk test (6MWT), COPD Assessment Test (CAT), modified Medical Research Council (mMRC), monitoring of physical activity in daily life, and isometric quadriceps muscle strength were assessed pre- and post-intervention.

Growing evidence has indicated a potential association between maternal consumption of caffeine and impaired cognition and behavior in rodent offspring. However, potential sex differences, as well as caffeine-related effects in subsequent generations are still poorly investigated. We aimed to investigate the impact of pre-and/or neonatal exposition to caffeine on the neurodevelopment of male and female mice offspring.

Despite extensive efforts to unravel tumor behavior and develop anticancer therapies, most treatments fail when advanced to clinical trials. The main challenge in cancer research has been the absence of predictive cancer models, accurately mimicking the tumoral processes and response to treatments. The tumor microenvironment (TME) shows several human-specific physical and chemical properties, which cannot be fully recapitulated by the conventional 2D cell cultures or the animal models.

Introduction: Bovine tuberculosis is one of the primary infectious diseases affecting cattle. Although several countries have managed to eradicate this zoonosis it remains endemic and uncontrolled across many countries in Africa, Asia, Latin America, and the Middle East. Brazil launched its national control and eradication program in 2001, and since then, epidemiological studies have been carried out to define optimal control strategies and to enable the management of the process in each region.

This study aimed to analyze the influence of operational parameters (foaming agent concentration, agitation time, and drying temperature) on the characteristics of the final product and the foam drying process of Momordica charantia L. leaves, in addition to performing mathematical modeling of the experimental data. The foam characteristic was most influenced by the foaming agent concentration, where the increase in this variable increased its stability, reaching the highest index of 0.
