A low-cost, DIY tourniquet simulator with built-in self-assessment for prehospital providers in Guatemala city.

Background: Hemorrhage is the leading cause of preventable death after trauma. In high-income countries first responders are trained in hemorrhage control techniques but this is not the case for developing countries like Guatemala. We present a low-cost training model for tourniquet application using a combination of virtual and physical components.

Proceedings of a Workshop to Promote Community Health Worker Interventions in Nephrology.

Latinx populations face a higher burden of kidney failure and associated negative outcomes compared with non-Latinx White populations, despite sharing a similar prevalence of CKD. Community health worker (CHW) interventions have been shown to improve outcomes for Latinx individuals, but they are largely underutilized in kidney disease. We convened a workshop of four ongoing kidney disease CHW programs to identify successes, challenges, potential solutions, and needed research to promote CHW programs for Latinx individuals with kidney disease.

Deep Learning-Based Image Registration in Dynamic Myocardial Perfusion CT Imaging.

Registration of dynamic CT image sequences is a crucial preprocessing step for clinical evaluation of multiple physiological determinants in the heart such as global and regional myocardial perfusion. In this work, we present a deformable deep learning-based image registration method for quantitative myocardial perfusion CT examinations, which in contrast to previous approaches, takes into account some unique challenges such as low image quality with less accurate anatomical landmarks, dynamic changes of contrast agent concentration in the heart chambers and tissue, and misalignment caused by cardiac stress, respiration, and patient motion. The introduced method uses a recursive cascade network with a ventricle segmentation module, and a novel loss function that accounts for local contrast changes over time.

Bovine Interferon-Tau Activates Type I interferon-Associated Janus-signal Transducer in HPV16-positive Tumor Cell.

The mechanisms of signal transduction by interferon-tau (IFN-τ) are widely known during the gestation of ruminants. In trophoblast cells, IFN-τ involves the activation of the JAK-STAT pathway, and it can have effects on other cell types, such as tumor cells. Here we report that the HPV16-positive BMK-16/myc cell treated with ovine IFN-τ, results in the activation of the canonical JAK-STAT and non-canonical JAK-STAT pathway.

[The medical care in the practice of football. its early process of institucionalization in Córdoba in the first decades of the 20th century].

The article examines the initial advances in the process of medicalización of the practice of football in the sports associations of Córdoba in the first decades of the 20th century. The objective is to investigate how, in the interaction between the players and these entities, there was becoming institutionalized the access of the sportsmen to medical care. In the research we analyze the development of football as a factor of health and hygiene, the evolution of the medical attention to the players and his process of decentralization as result of its spatial anchorage in the sports entities.
