Gla-Rich Protein Is Associated with Vascular Calcification, Inflammation, and Mineral Markers in Peritoneal Dialysis Patients.

: Vascular calcification (VC) is a crucial risk factor for cardiovascular diseases (CVD), particularly in chronic kidney disease (CKD) populations. However, the specific relationship between VC and end-stage renal disease (ESRD) patients undergoing peritoneal dialysis (PD) remains to be fully understood. The identification of new biomarkers to improve VC diagnosis and monitoring would significantly impact cardiovascular risk management in these high-risk patients.

Geogenic characterisation of airborne particles from the former Regoufe mining area.

Mining operations contribute to higher environmental contaminant levels, such as particulate matter (PM) hosting potentially toxic elements (PTE). This study aimed to comprehensively characterise atmospheric PM in an environment impacted by former tungsten-tin mining exploration at Regoufe mine (Arouca, Portugal). Although this is a deactivated mine, its location near population clusters and integration into a Geopark belonging to the "World Geoparks Network" with frequent presence of hikers highlight the importance of air quality monitoring to keep its Geopark classification.

Physiologic Outcomes after Thiafentanil and Xylazine Immobilization in Free-Ranging Moose (Alces alces).

Effects on physiology were evaluated in 49 free-ranging moose (Alces alces), 11 adult males, 36 females, two of unknown sex) in Minnesota, USA, immobilized by helicopter darting with thiafentanil (10 mg) and xylazine (30 mg) in February 2020 and March 2021. Pursuit time (PT), induction time (IT), recumbency time (RT), recovery time (RC), temperature (T), and body position were recorded. For 14 females, respiratory rate (RR), pulse rate (PR), and pulse oximetry (SpO2) were obtained before and at 1, 5, and 10 min after 4 L/min nasal oxygen supplementation was started; pH, lactate (Lac), arterial oxygen (PaO2), and carbon dioxide (PaCO2) tensions were obtained pre-treatment and 5 min post-treatment.

LEVELS OF EVIDENCE IN ONCOLOGIC-ORTHOPEDIC STUDIES - ACTA ORTOP BRAS (1993-2022).

Objectives: to identify oncological-orthopedic studies published in Acta Ortopédica Brasileira over three decades; to classify them according to the type and level of evidence (LE); to observe the inter-rater agreement in the classification of studies; to analyze the studies retrospectively, according to levels of evidence; and to outline the evolution of the evidence in the study period.

Methods: Descriptive analyses were performed with absolute and relative frequencies of studies published between 1993 and 2022. Inter-rater agreement was analyzed by percentage of agreement and Kappa statistic (95%CI).

Evaluating the Efficacy of a Pre-Established Lipid-Lowering Algorithm in Managing Hypercholesterolemia in Patients at Very High Cardiovascular Risk.

Background: Recent data from European studies (EUROASPIRE V, DA VINCI, SANTORINI) indicate that achieving the LDL cholesterol (LDL-C) target in patients at very high cardiovascular risk is uncommon. Additionally, using a combination therapy involving statins and ezetimibe remains infrequent.

Methods: A single-center assessment of a pre-defined lipid lowering treatment algorithm's effectiveness at achieving the LDL-C target in patients at very high cardiovascular risk one month and one year after hospitalization.
