Background: Important risk factors for cutaneous melanoma (CM) are recognized, but standardized scores for individual assessment must still be developed.
Objectives: The objective of this study was to develop a risk score of CM for a Brazilian sample.
Methods: To verify the estimates of the main risk factors for melanoma, derived from a meta-analysis (Italian-based study), and externally validate them in a population in southern Brazil by means of a case-control study. A total of 117 individuals were evaluated. Different models were constructed combining the summary coefficients of different risk factors, derived from the meta-analysis, multiplied by the corresponding category of each variable for each participant according to a mathematical expression.
Results: the variable that best predicted the risk of CM in the studied population was hair color (AUC: 0.71; 95% CI: 0.62-0.79). Other important factors were freckles, sunburn episodes, and skin and eye color. Consideration of other variables such as common nevi, elastosis, family history, and premalignant lesions did not improve the predictive ability of the models.
Conclusion: The discriminating capacity of the proposed model proved to be superior or comparable to that of previous risk models proposed for CM.

Background: College students significantly decrease physical activity (PA) over the course of a four-year degree, increasing the risk for chronic disease. Research shows that psychological constructs impact behavior and goal attainment. However, little is known regarding the effect of psychological variables on PA levels in students.

Background: Locoregional therapy (LRT) in patients with hepatocellular carcinoma (HCC) before liver transplantation (LT) has a role in improving the tumor biology and post-LT survival outcome apart from downstaging and bridging. We retrospectively analyzed our database of adult living donor liver transplants (LDLT) for HCC, to compare the survival outcomes in Group-1 (upfront-LT, HCC within Milan/UCSF/AFP<1000 ng/ml) and Group-2 (LT post-LRT, HCC beyond UCSF/irrespective of tumor burden with AFP>1000 ng/ml). We also explored the risk factors for recurrence on follow-up.

Background: Beta-lactams remain the first-line treatment of infections despite the increasing global prevalence of penicillin-resistant/non-susceptible strains. We conducted a cross-sectional household survey in a rural community in northern Vietnam in 2018-2019 to provide prevalence estimates of penicillin non-susceptible (PNSP) carriage and to investigate behavioural and environmental factors associated with PNSP colonization. The data presented will inform the design of a large trial of population-based interventions targeting inappropriate antibiotic use.

Background: This study aims to investigate the association between vitamin D levels and the risk of severe acute exacerbations of chronic obstructive pulmonary disease (AECOPD).
Methods: We conducted a prospective observational study with 636 COPD patients admitted for exacerbations between January 2021 and December 2022. Patients were categorized based on serum 25-hydroxyvitamin D levels: severe deficiency (<10 ng/mL), deficiency (10-20 ng/mL), insufficiency (20-30 ng/mL), or sufficiency (>30 ng/mL).
