Evaluation of Probiotic Effects on the Growth Performance and Microbiome of Nile Tilapia () in a High-Density Biofloc System.

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.

Bullying in adolescents across three years in the context of the COVID-19 pandemic: a repeated cross-sectional and prospective analysis.

Background: Bullying has been identified as a risk factor for many issues among adolescents. Although it was already considered a public health issue in Brazil before the COVID-19 pandemic, little is known about how the pandemic and associated public health measures have affected bullying behavior.

Objective: To explore changes in bullying victimization and perpetration among Brazilian high school students from 2019 to 2022.

Health of quilombola children as a challenge for the Sustainable Development Goals: a scoping review.

Objective: to map the literature on quilombola children's health and its relationship with the Sustainable Development Goals.

Method: a scoping review, which followed the JBI protocol and the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. Searches were conducted in the LILACS, BDENF, Web of Science, Scopus, MEDLINE databases and Google Scholar platform.

Carbon-dot pequi-nut in the development of immunosensor to detect pathogenic bacteria.

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).

Iron management and exercise training in individuals with chronic kidney disease: lived experiences.

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.
