Prevention and Mass Screening of TB in Prisons in Paraguay

The goal of this interventional study is to evaluate three tuberculosis (TB) screening and prevention strategies in prisons in Paraguay. The main questions it aims to answer are: * Which strategy is more effective for reducing the incidence rate of active TB? * Which strategy is more effective for reducing the TB infection rate? * Are these strategies safe, feasible, and cost-effective in prison settings? Researchers will compare three cluster-based, non-randomized programmatic strategies implemented in three prisons. These strategies differ in the frequency of screening, the diagnostic methods used, and the approach to tuberculosis preventive therapy (TPT). Participants will: * undergo informed consent and clinical evaluation * receive TB screening through symptom assessment, chest digital X-ray with CAD, and rapid molecular testing, depending on site strategy * undergo IGRA testing and preventive therapy assessment, depending on the assigned strategy * be followed for 18 months, with screening rounds every 6 months or annually depending on the prison

Analysis of the Evolution of Mortality in an Intensive Care Unit

The intensive care units is of the main components of modern healthcare systems. Formally, its aim is to offer the critically ill health care fit to their needs; ensuring that this health care is appropriate, sustainable, ethical and respectful of their autonomy. Intensive medicine is a cross-sectional specialty that encompasses a broad spectrum of pathologies in their most severe condition, and specifically has as its foundation the practice of comprehensive care of the patient with organ dysfunction and susceptible to recovery. Although critically ill patients are a heterogeneous population, they have in common the need for a high level of care, often requiring the use of high technology, specific procedures for the support of organ dysfunction and the collaboration of other medical and surgical specialties for their management and treatment. Since their origins in the late 1950s, intensive care units have been adapting to the changes arising from the best scientific evidence. In the late 1990s and early 2000s, there were some successful clinical trials published that had tested alternative management strategies in the ICU. Mechanical ventilation is an intervention that defines the critical care specialty. Between 1970 and the 1990s, the management focused on normalizing arterial blood gas with aggressive mechanical ventilation. Over the ensuing decades, it became apparent that performing positive pressure ventilation worsened lung injury. The pivotal moment in the mechanical ventilation story would be the low versus high tidal volume trial. This trial shifted the focus away from normalizing gas exchange to reducing harm with mechanical ventilation. Further, it paved way for further trials testing ventilation interventions (PEEP strategy, prone position ventilation) and nonventilation interventions (neuromuscular blockade, corticosteroids, inhaled nitric oxide, extracorporeal gas exchange) in critically ill patients. That evidence-based intensive care medicine has undoubtedly had an influence on the outcome of critically ill patients, in general, and, particularly, of patients requiring mechanical ventilation. Temporal changes in mortality over the time have been scarcely reported for patients admitted to intensive care unit. Objective of this study is to estimate the changes over the time in several outcomes in the patients admitted to an 18-beds medical-surgical intensive care unit from 1991 (year of start of activity) to 2026

Coronary Artery Calcification in Type 2 Diabetes Mellitus (USCAC Study)

Coronary artery calcification (CAC) is a common complication of type 2 diabetes mellitus(T2DM), which can significantly increase all-cause mortality and the incidence of serious cardiovascular events, and increase the burden of the national economy. The epidemiological characteristics and the clinical progress of CAC are still not clear. Moreover, the pathogenesis of CAC has not yet been fully elucidated, and lack of specific diagnostic indicators. Arterial calcification is an active, reversible, and multifactorial biological process like bone formation. It is generally believed that early detection of calcification lesions and active targeted treatment may be the key to prevention and treatment of vascular calcification. In addition, statins are commonly used in patients with dyslipidemia and can stabilize CAC plaque. However, the timing, dosage and effect of statins are controversial. Moreover, our previous study found that the expression of miR-32 is significantly elevated in patients with CAC, and can promoting vascular calcification. Herein, this study is to conduct a prospective cohort study on T2DM patients with CAC in Hunan province through a multidisciplinary and multi-center cooperation model, the main research objectives include the following three parts: ① To identify the prevalence, incidence, and characteristics of CAC in T2DM patients in Hunan province, and to build a risk assessment model. ② To observe the effects of statins on the occurrence and development of CAC in patients with T2DM, and to provide clinical data for the improvement of medication guidelines; ③To observe the dynamic changes of serum miR-32 in the progression of CAC in patients with T2DM, and to explore its possibility as a serological diagnosis or prognostic bio-maker of CAC. The completion of this research project is expected to bring a new breakthrough in the field of early diagnosis, prognosis evaluation, and intervention treatment of patients with T2DM combined with CAC, and provide an important reference for the formulation of cardiovascular disease prevention and control strategy.
