Introduction: Intestinal parasitism has been a challenge to overcome for the Mexican deworming campaign and this study determined the prevalence of these infections in schoolchildren treated with albendazole in Northwestern Mexico. Methods: Study sites in marginal conditions, with gastrointestinal infections and albendazole intervention were selected. The Faust and Kato Katz techniques were used to identify the parasites spp. and the NCSS software was used for statistical analysis. Results: A total of 450, 389 and 364 schoolchildren participated in 2005, 2006, and 2007 respectively during this study. The mean age was 7.9 (±1.3). The estimated prevalences were of 42%, 30% and 37% for protozoa infections, and 11%, 12% and 11% for helminth infections in 2005, 2006 and 2007 respectively. Conclusion: The education strategies should be integrated into the Mexican deworming campaign.

Background: Cardiac involvement and the consequences of inflammation induced by SARS-CoV2 infection could have catastrophic long-term consequences. Left ventricular mechanics could identify a specific pattern of myocardial fiber damage in patients infected with COVID-19. To our knowledge there are no publications referring to the global description of ventricular mechanics in patients with COVID-19. Objective: To describe left ventricular mechanics in hospitalized patients with COVID-19. Methods: In this cross-sectional study, we included 40 hospitalized patients with confirmed diagnostic of COVID-19, from April 11, 2020, to September 6, 2020. Demographic and laboratory data, clinical and echocardiographic characteristics were collected, as well as events during hospitalization. Left ventricular deformation was analyzed and reported. Results: Subclinical dysfunction was observed in 82.5% (left ventricular longitudinal strain [LVGLS] -17.05% and global circumferential strain [GCS] -18.6%) of the patients, likewise, the mean twist and apical rotation were preserved, and even increased as part of the compensating mechanism to maintain the ejection fraction. Conclusion: In patients hospitalized with COVID-19, despite having a normal left ventricular ejection fraction, subclinical myocardial damage was found, manifested by a decrease in Global Longitudinal Strain (GLS) and Global Circumferential Strain (GCS). This behavior is similar to that of cardiomyopathies in the early stage of the disease, and given the pathophysiological mechanisms involved in the disease, its long-term consequences should be monitored and evaluated.
