We aimed to perform cross-cultural adaptation of the Interprofessional Collaboration Scale (IPC-BR) and to evaluate evidence of its validity for the Brazilian hospital context. The research consisted of six steps: translation of the instrument into the new language, synthesis of the translated versions, back-translation, synthesis of the versions in the original language, evaluation of the syntheses by an expert committee, and pilot testing or pretesting and validation of the internal structure of the items of the instrument. The pilot testing involved 4 translators, 14 judges, and 30 healthcare professionals; the validation of the internal structure involved 686 professionals including nurses, physicians and physiotherapists.

Background: The impact of ankyloglossia (tongue-tie) on breastfeeding outcomes may be overestimated and surgical treatment in newborns remains a controversial topic. The aim of the present study was to assess and quantify the impact of ankyloglossia in newborns on breastfeeding self-efficacy at 14 days of life.
Methods: A birth cohort study was conducted involving mothers and newborns soon after childbirth at a public hospital in the city of Canoas, southern Brazil.

Significant changes in the proteome highlight essential metabolic adaptations for development and oxidative signaling induced by the treatment of young sugarcane plants with hydrogen peroxide. These adaptations suggest that hydrogen peroxide acts not only as a stressor but primarily as a signaling molecule, triggering specific metabolic pathways that regulate growth and plant resilience. Sugarcane is a crucial crop for sugar and ethanol production, often influenced by environmental signals.

Objective: Increased intracranial pressure (ICP) can worsen the clinical condition of traumatic brain injury (TBI) patients. One non-invasive and easily bedside-performed technique to estimate ICP is ultrasonographic measurement of optic nerve sheath diameter (ONSD). This study aimed to analyze ONSD and correlate it with ICP values obtained by intraparenchymal monitoring to establish the ONSD threshold value for elevated ICP and reference range of ONSD in severe TBI patients.

Purpose: This preclinical study explored the feasibility of assessing P-glycoprotein (P-gp) function in both brain and gastrointestinal (GI) tract of rats using positron emission tomography (PET) following oral administration of [F]MC225. Different oral administration protocols were evaluated, and radioactivity uptake was compared with uptake following intravenous administration.
Procedures: Twelve male Wistar rats were divided into four groups and subjected to intravenous or oral [F]MC225 administration protocols: G (intravenous route), G (oral administration without fasting), G (oral administration with fasting), and G (oral administration with fasting following administration of the P-gp inhibitor tariquidar).

Zinc is an essential metal to living organisms, including corals and their symbiotic microalgae (Symbiodiniaceae). Both Zn(II) deprivation and overload are capable of leading to dysfunctional metabolism, coral bleaching, and even organism death. The present work investigated the effects of chemically defined Zn species (free Zn, ZnO nanoparticles, and the complexes Zn-histidinate and Zn-EDTA) over the growth of the dinoflagellates Symbiodinium microadriaticum, Breviolum minutum, and Effrenium voratum, and on the trypsin-like proteolytic activity of the hydrocoral Millepora alcicornis.

Basal ganglia hemorrhage (BGH) is a prevalent site for intracerebral hemorrhage. Although neuroendoscopy (NE) surgery has emerged as a less invasive alternative to craniotomy (CT), the optimal surgical method remains debatable. This systematic review and meta-analysis aimed to compare the efficacy and safety of NE versus CT in the management of BGH.

Gold-based (Au) nanostructures are efficient catalysts for CO oxidation, hydrogen evolution (HER), and oxygen evolution (OER) reactions, but stabilizing them on graphene (Gr) is challenging due to weak affinity from delocalized [Formula: see text] carbon orbitals. This study investigates forming metal alloys to enhance stability and catalytic performance of Au-based nanocatalysts. Using ab initio density functional theory, we characterize [Formula: see text] sub-nanoclusters (M = Ni, Pd, Pt, Cu, and Ag) with atomicities [Formula: see text], both in gas-phase and supported on Gr.

Characterizing the dynamics of microbial community succession in the infant gut microbiome is crucial for understanding child health and development, but no normative model currently exists. Here, we estimate child age using gut microbial taxonomic relative abundances from metagenomes, with high temporal resolution (±3 months) for the first 1.5 years of life.

Male androgenetic alopecia (MAA) is quite common and worsens with age, with a significant impact on quality of life, and is increasingly a reason for consultation with a dermatologist. The etiopathogenesis of MAA is multifactorial and genetic and hormonal influences stand out. MAA starts with the process of follicular miniaturization in diverse phenotypic patterns.

Faced with the increased frequency of zoonotic spillover in recent decades, emerging vector-borne diseases from nonhuman primates pose a significant threat to global public health. Understanding transmission dynamics driven by arthropod vectors between wildlife populations is critical for surveillance, modeling, and mitigation. Elevated canopy-level sampling is a valuable approach for elucidating vector behavior and sylvatic transmission.

Objectives: To characterize two experimental zirconia bilayer materials compared to their monolithic controls, before and after hydrothermal aging.
Methods: Commercial zirconia powders were utilized to fabricate two bilayer materials: 3Y-TZP+ 5Y-PSZ (3Y+5Y/BI) and 4Y-PSZ+ 5Y-PSZ (4Y+5Y/BI), alongside control groups 3Y-TZP (3Y/C), 4Y-PSZ (4Y/C), and 5Y-PSZ (5Y/C). Compacted specimens were sintered (1550 °C- 2 h, 3 °C/min), and half of them underwent hydrothermal aging (134 °C-20h, 2.

Removal of the buccal fat pad can be considered safe as long as there is a detailed analysis of anatomical landmarks. The objective of this study was to estimate the prevalence of intra- and postoperative complications resulting from buccal fat pad removal through a systematic review. The search strategy involved observational and/or interventional studies in humans that included at least one case of buccal fat pad removal with a description of the surgery, postoperative progress, and complications.

This study aimed to develop patches containing quercetin-loaded microcapsules and to evaluate their in vitro and in vivo safety and efficacy in preclinical surveys. A set of in vitro experiments evidenced the virucidal activity of quercetin against the HSV-1-KOS (sensitive to acyclovir) and HSV-1-AR (resistant to acyclovir) strains, with improved outcomes upon the first. The patches presented a homogeneous aspect, were easily handled, had a suitable bioadhesion, and possessed mechanical properties of soft and weak material, besides a pH compatible with human skin.

Background: Intrauterine growth restriction (IUGR) is a severe condition in which the fetus fails to reach its genetically predetermined growth potential, impairing prenatal development and predisposing individuals to postnatal consequences that may persist into adulthood. Although fetal mechanisms such as the brain-sparing effect have been proposed to protect the brain against IUGR-related deficits, the extent of this protection remains unclear.
Objective: To conduct a systematic review that demonstrates prenatal morphofunctional abnormalities in the brain of individuals with IUGR.
