Gaucher disease (GD) is a rare genetic disorder with multi-system involvement. Liver fibrosis is a long-term complication of GD, potentially leading to cirrhosis, end-stage liver disease, and hepatocellular carcinoma. There are currently no validated clinical tools for the monitoring of liver fibrosis in patients with GD.

: Avoidance of ultra-processed foods (UPFs) has been recommended to achieve a healthy diet, but whether it applies equally to all UPFs is uncertain. We evaluated individual UPF subgroups in the prediction of cardiometabolic and mental health outcomes. : The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is an occupational cohort study of 15,105 adults (35-74 years) recruited in 2008-2010.

Objective: This paper evaluates the accuracy of C-reactive protein (CRP), leukocyte count, and neutrophil-to-lymphocyte ratio (NLR) for diagnosing tubo-ovarian abscess (TOA) and assessing the cost-effectiveness of different treatment regimens for pelvic inflammatory disease (PID), with and without TOA.
Method: A retrospective cohort study was conducted between January 1, 2003, and December 30, 2021, including women aged 13-80 years diagnosed with PID. The analysis focused on the incremental cost-effectiveness ratio of different treatment regimens.

Background: Current literature highlights a gap in precise stroke cost data for Latin America. This study measures the real costs associated with acute ischemic stroke care in Latin America using Time-Driven Activity-Based Costing (TDABC). The findings aim to lay a solid foundation for adopting value-based healthcare (VBHC) strategies in the region.

Background And Objectives: To compare the diagnostic performance of an immunoassay for plasma concentrations of phosphorylated tau (p-tau) 217 with visual assessments of fluorine-18 fluorodeoxyglucose [F]FDG-PET in individuals who meet appropriate use criteria for Alzheimer dementia (AD) biomarker assessments.
Methods: We performed a retrospective analysis of individuals with early-onset (age <65 years at onset) and/or atypical dementia (features other than memory at onset), who were evaluated at a tertiary care memory clinic. All participants underwent measurements of CSF biomarkers (Aβ42, p-tau181, and total tau levels), as well as [F]FDG-PET scans, amyloid-PET scans, and plasma p-tau217 quantifications.

Dental morphology varies greatly throughout evolution, including in the human lineage, but little is known about the biology of this variation. Here, we use multiomics analyses to examine the genetics of variation in tooth crown dimensions. In a human cohort with mixed continental ancestry, we detected genome-wide significant associations at 18 genome regions.

Introduction: Nationwide databases from large countries may provide real-world evidence about COVID-19 vaccine effectiveness (VE). This study sought to assess the VE of BNT162b2 and CoronaVac against COVID-19-related severe outcomes in school-aged children and adolescents during the Omicron wave of the COVID-19 pandemic in Brazil.
Methods: A nationwide population-based cohort study compared the incidence risk ratios (IRRs) of hospitalization due to COVID-19-associated severe acute respiratory syndrome (SARS), need for invasive ventilatory support, and death among school-aged children (age 5 to 11 years) and adolescents (age 12 to 17 years), stratified by vaccination status (none, one, or two doses), in 2022.

Background/objectives: The optimal dietary approach for managing glycemic and metabolic control in type 2 diabetes (T2D) is still uncertain, though it should be tailored for clinical settings. Therefore, we sought to assess the impact of a multicomponent nutritional strategy on glycemic control in T2D patients within a public health system.
Methods: NUGLIC was an open-label, parallel-group, superiority, multicenter randomized controlled trial.

Background/objectives: Vitamin and/or mineral supplements are designed to correct micronutrient deficiencies or maintain adequate intake. However, evidence suggests the indiscriminate use of these products, particularly among populations that already meet their micronutrient requirements through diet. This study aims to estimate the prevalence of vitamin and/or mineral supplement use and assess the dietary intake of micronutrients among users and non-users in the Brazilian adult and elderly populations.

Background: Detraining refers to the decline in physical fitness that occurs after the cessation of exercise, compromising the adaptations resulting from regular exercise training. To understand how long the benefits acquired from an exercise program can be maintained, the present study evaluated the detraining effects of a 4-week exercise cessation period in older adults who performed combined training at various weekly frequencies for 12 weeks.
Methods: This randomized controlled trial assigned participants to one of two training programs: a combined training program twice a week (CT2) or four times a week (CT4) over a period of 12 weeks, followed by a four-week detraining period.

Background: Disturbances in the gut microbiota may act as mechanisms influencing the interplay between dietary factors and metabolic disorders. Studies have demonstrated that these alterations are associated with the diagnosis of polycystic ovary syndrome (PCOS). Within this context, we aimed to investigate associations between gut microbiota, gut-derived metabolites (short-chain fatty acids [SCFAs] and indole-3-propionic acid [IPA]), and dietary intake in women with PCOS.

Background: Cancer is an important cause of morbidity and mortality after solid organ transplants. Skin cancer is the most prevalent non-lymphoid malignancy occurring during heart transplantation follow-up. Due to the complexity of immunosuppressive therapy and the high prevalence and incidence of skin cancer in this population, dermatologists play an important role in the short and long-term follow-up of heart transplant recipients.

Background: Transcranial direct current stimulation (tDCS) might modulate neural activity and promote neural plasticity in patients with fibromyalgia (FM). This multi-group randomized clinical trial compared home-based active tDCS (HB-a-tDCS) on the left dorsolateral prefrontal cortex (l-DLPFC) or home-based sham tDCS (HB-s-tDCS), and HB-a-tDCS or HB-s-tDCS on the primary motor cortex (M1) in the connectivity analyses in eight regions of interest (ROIs) across eight resting-state electroencephalography (EEG) frequencies.
Methods: We included 48 women with FM, aged 30 to 65, randomly assigned to 2:1:2:1 to receive 20 sessions during 20 minutes of HB-a-tDCS 2mA or HB-s-tDCS, over l-DLPFC or M1, respectively.
