BASIC AND CLINICAL INSIGHTS IN CATECHOLAMINERGIC (FAMILIAL) POLYMORPHIC VENTRICULAR TACHYCARDIA.
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially lethal disease, whose characteristic ventricular tachycardias are adrenergic-dependent. Although rare, CPVT should be considered in the differential diagnosis of young individuals with exercise-induced syncope. Mutations in five different genes (RYR2, CASQ2, CALM1, TRDN, and TECRL) are associated with the CPVT phenotype, although RYR2 missense mutations are implicated in up to 60 % of all CPVT cases. ⋯ Beta-adrenergic and calcium-channel blockers are the cornerstones of treatment due to the catecholaminergic dependence of the arrhythmias. Unresponsive patients are treated with an implantable cardioverter-defibrillator to reduce the risk of sudden cardiac death. In the present article, a brief review of the genetic and molecular mechanisms of this intriguing disease is provided.

Observational Study
A MULTIVARIATE PROGNOSTIC SCORE FOR PREDICTING MORTALITY OF ACQUIRED IMMUNODEFICIENCY SYNDROME PATIENTS WITH HYPOXEMIC RESPIRATORY FAILURE AND PNEUMOCYSTIS JIROVECI PNEUMONIA.
Severe hypoxemic respiratory failure (SHRF) due to Pneumocystis jiroveci pneumonia (PJP) in AIDS patients represents the main cause of admission and mortality in respiratory intensive care units (RICUs) in low- and middle-income countries. ⋯ This scoring system is a potentially useful tool to assist clinicians, in low- and medium-income countries, in estimating the RICU and inhospital mortality risk in patients with HIV/AIDS and SHRF caused by PJP.

The incidence of colorectal cancer (CRC) in the US has declined. The decreasing trend is observed in non-Hispanic Whites, Blacks, and Hispanics. However, close analysis of the trends demonstrates that the decline among Hispanics is less than other races/ethnicities. We investigate the burden of CRC in Hispanics living near the U.S.-Mexico border, a subpopulation of Hispanics composed primarily of individuals of Mexican origin. ⋯ Our study unveils a significant disparity in CRC incidence among Hispanics living near the U.S.-Mexico border, disproportionally affecting men ≥ 50 years of age. Socioeconomic and cultural/lifestyle factors are likely contributing to these disparities.

In Mexico, the quality of health care for human immunodeficiency virus (HIV) patients is unknown. The study objectives were to develop quality of care (QoC) indicators for outpatient care of HIV patients, evaluate the quality of the processes of care (QPC) and outcomes, and analyze the association between the QPC and viral suppression among HIV patients. ⋯ Evaluation of the QoC for HIV patients is essential to identify and address gaps in health-care quality to increase the probability of viral suppression.

The frequency of depression and anxiety symptoms in Spanish-speaking patients suffering from rheumatic conditions is unknown when using self-administered detection tools. ⋯ An unexpected and unusually high frequency of undiagnosed depression and anxiety symptoms was found in rheumatic patients. Self-administered screening tools adapted to the Spanish language are useful and may help clinicians to suspect these conditions.
