Background And Hypothesis: In patients with advanced chronic kidney disease (CKD), the lifespan of red blood cells (RBC) is often shortened, a condition attributed to the "uremic milieu." We reported recently that the uremic solute 3-carboxy-4-methyl-5-propyl-2-furanpropionate (CMPF) shares structural similarities with Jedi1, a chemical activator of the mechanosensitive cation channel Piezo1, whose activation increases calcium influx into cells. Against this backdrop, we hypothesized that CMPF may induce premature RBC death (eryptosis) through prolonged CMPF-induced activation of Piezo1 located on RBC.

Article Synopsis
  • COVID-19 causes hypercytokinemia, an imbalance of inflammatory cytokines, which complicates treatment, especially in severe cases.
  • A study tracked cytokine levels in SARS-CoV-2 patients over time, finding that elevated levels predicted mortality, particularly for IL-4 and IL-1β.
  • The research indicates that changes in levels of specific cytokines like IFN-γ and IL-6 are linked to patient outcomes, emphasizing the role of cytokine dynamics in predicting severe COVID-19 results.

Article Synopsis
  • The novel HLA-C*01:273 allele is a recently identified genetic variation related to human leukocyte antigen (HLA), which plays a crucial role in the immune system.
  • This allele was first reported in a bone marrow donor from Brazil, highlighting its geographical significance.
  • The discovery of this allele could have important implications for bone marrow transplantation and understanding genetic diversity in different populations.

Objectives: Children with behavioral health conditions often experience agitation when admitted to children's hospitals. Physical restraint should be used only as a last resort for patient agitation because it endangers the physical and psychological safety of patients and employees. At the medical behavioral unit (MBU) in our children's hospital, we aimed to decrease the weekly rate of physical restraint events per 100 MBU patient-days, independent of patient race, ethnicity, or language, from a baseline mean of 14.

Cardiovascular diseases (CVD), mainly ischemic heart disease and stroke, is the main cause of death worldwide and each year more people die from CVD than from any other cause. These data call for a paradigm shift, where health promotion and cardiovascular prevention will acquire a central role in health policies. From this perspective, dedicating time during the consultation to promoting the acquisition of heart-healthy habits would be indicated in all individuals, regardless of cardiovascular risk classification, the role of the internist being fundamental.

Iron (Fe) is the fourth most abundant element on the planet, and iron-oxidising bacteria (FeOB) play an important role in the biogeochemical cycle of this metal in nature. FeOB stands out as Fe oxidisers in microaerophilic environments, and new members of this group have been increasingly discussed in the literature, even though their isolation can still be challenging. Among these bacteria is the Gallionellaceae family, mainly composed of neutrophilic FeOB, highlighting Gallionella ferruginea, and nitrite-oxidiser genera.

Feeding animals with lactobacilli strains is a biotechnological strategy to improve production, food quality, and animal health. Thus, this study aimed to select new lactic acid bacteria (LAB) able to improve laying hens health and egg production. Forty Bovans White layers (two days old) were randomly divided into four experimental groups that receive an oral gavage with saline solution (control group) or with one of the three lactobacilli selected (KEG3, TBB10, and KMG127) by their antagonistic activity against the foodborne pathogen Bacillus cereus GGD_EGG01.

Increasingly, youth experiencing mental health crises present to acute care medical hospitals and "board" on medical units due to inpatient psychiatric bed shortages. We conducted a retrospective cohort study of children experiencing mental health boarding at a US children's hospital from October 2020 to September 2022. We examined associations between patients' characteristics and their disposition and outcomes.

Article Synopsis
  • * Collaborative efforts led to the collection of 422 chikungunya virus genomes from 12 states, offering insights into how the virus has spread and evolved across the country.
  • * Analysis of the genetic data revealed two distinct subclades of the virus and highlighted Northeast Brazil as the main spreading region, with immune system factors potentially influencing its genetic diversity.

Article Synopsis
  • Mosquito-borne diseases like Yellow Fever, Zika, Chikungunya, and Dengue are causing big health problems in Brazil, especially since Chikungunya started spreading in 2014.
  • In two years (2021-2022), scientists created 422 new virus genomes from 12 states to better understand how Chikungunya spreads, as there were over 312,000 reported cases.
  • They discovered that the northeast region of Brazil is the main area where the virus is spreading to other places and found that certain factors in the immune system might be changing the virus's genes in Brazil.

During the COVID-19 pandemic, hospitals around the world were forced to reorganize their processes in an attempt to contain the spread of the virus while still providing adequate care to patients. In the Pediatric Intensive Care Unit (PICU) setting, changes in family visitation protocols and restrictions on parent chaperones during hospitalization, as well as other changes, interfered with care. Based on a narrative review of the literature, supported by the authors' observations in practice, we aimed to describe the impact of the pandemic on patient and family-centered care (PFCC) in the PICU environment, especially regarding the presence of family members, family support, and communication with patients and their families, as well as the effects of changes in these practices on the mental health of those involved.

Background: Limnoperna fortunei is a freshwater bivalve mollusc originally from southern Asia that invaded South America in the 1990's. Due to its highly efficient water pumping and filtering, and its capacity to form strong adhesions to a variety of substrates by byssus thread, this invasive species has been able to adapt to several environments across South America, causing significant ecological and economic damages. By gaining a deeper understanding of the biological and ecological aspects of L.

Interactions between parasites during co-infections are often complex and can impact immunization and treatment programmes, as well as disease outcomes and morbidity. However, little is known about these interactions and the mechanisms involved. In this study, a coproparasitological survey was carried out in school-age children living in endemic areas of parasitic infection in the state of Sergipe, Northeastern Brazil.

The widespread use of conventional chemical antifungal agents has led to worldwide concern regarding the selection of resistant isolates. In this scenario, antimicrobial photodynamic treatment (APDT) has emerged as a promising alternative to overcome this issue. The technique is based on the use of a photosensitizer (PS) and light in the presence of molecular oxygen.

In keeping with the process of institutionalization of evaluation of primary healthcare in Brazil, we developed the Evaluative Matrix of the Longitudinal Bond (MAVIL in Portuguese), a simple and concise evaluative tool. MAVIL is structured according to three dimensions in the concept of longitudinal bond: Dimension 1 - recognition of the basic health unit (UBS in Portuguese) as a regular source of care, Dimension 2 - healthcare worker/patient interpersonal relationship, and Dimension 3 - continuity of information. The instrument consists of a structured set of 12 criteria, 20 indicators and respective questions, and verification items submitted to various validation stages.
