Classical swine fever (CSF) is one of the most important re-emergent swine diseases worldwide. Despite concerted control efforts in the Andean countries, the disease remains endemic in several areas, limiting production and trade opportunities. In this study, we aimed to determine the risk factors and spatiotemporal implications associated with CSF in Ecuador. We analysed passive surveillance and vaccination campaign datasets from 2014 to 2020; Then, we structured a herd-level case-control study using a logistic and spatiotemporal Bayesian model. The results showed that the risk factors that increased the odds of CSF occurrence were the following: swill feeding (OR 8.53), time until notification (OR 2.44), introduction of new pigs during last month (OR 2.01) and lack of vaccination against CSF (OR 1.82). The spatiotemporal model showed that vaccination reduces the risk by 33%. According to the priority index, the intervention should focus on and provinces. In conclusion, the results highlight the complexity of the CSF control programs, the importance to improve the overall surveillance system and the need to inform decision-makers and stakeholders.

Background: Bowel trauma, encompassing injuries to the small and large intestine, represents a significant medical challenge due to its potential for morbidity and mortality. Management of bowel injuries remains surgical, but multiple factors influence the outcome in these patients. This study provides an in-depth analysis of the high-risk features of hollow visceral trauma in the ICU setting and the corresponding mortality rates, shedding light on the critical factors that influence outcomes in these cases.

Background: Postoperative patients' risk for developing venous thromboembolism (VTE) can be predicted using the adapted Caprini risk assessment model which informs administration of postoperative VTE prophylaxis. The study aimed to assess the appropriateness of postoperative VTE prophylaxis of patients according to the adapted Caprini scores and investigate whether a patient's HIV status influenced postoperative VTE prophylaxis administration.
Methods: This cohort study included patients who had elective or urgent surgery at a tertiary hospital, Bloemfontein.

Background: Streptococcal Toxic Shock Syndrome (STSS) is a life-threatening condition caused by bacterial toxins. The STSS triad encompasses high fever, hypotensive shock, and a "sunburn-like" rash with desquamation. STSS, like Toxic Shock Syndrome (TSS), is a rare complication of streptococcal infec-tions caused by Group A Streptococcus (GAS), Streptococcal pyogenes (S.

Background: Plasma osteoprotegerin (OPG) has been linked to poor prognosis following stroke, but its impact on post-stroke cognitive impairment (PSCI) is unknown. The purpose of our work was to analyze the relationship of OPG with PSCI.
Methods: Our study included 613 ischemic stroke subjects with plasma OPG levels.

Exposure to heavy metals has been associated with affecting children's neurodevelopment, particularly increasing the risk of developing attention-deficit hyperactivity disorder (ADHD). The current exploratory study aims to investigate potential associations between presence of 15 different heavy metals in urine and ADHD. A total of 190 urine samples of participants from clinical and non-clinical population (non-ADHD = 66; ADHD = 124) aged between 6 and 15 years from Barcelona and Tarragona (Spain) were analysed.
