ABSTRACT
Indoor air conditioning is currently a topic of much interest, not only to save energy but also due to public health issues such as pandemics. This study focuses on the thermal comfort and air quality of a closed, air-conditioned space located in an extremely hot climate. Due to noise and weather conditions, the door and window of the space are kept closed at all times. The study uses computational fluid dynamics techniques and the finite element method. Average temperatures and CO2 concentrations, as well as effectiveness for temperature and concentration distribution, are calculated for the analysis. Results indicate that supplying air away from hot walls improves air quality and thermal comfort. Furthermore, there is an optimal Reynolds number that depends on the number of people inside the space. Due to the above, it is possible to find an ideal configuration that simultaneously allows for efficient energy use, helps to avoid the adverse effects of CO2 on daily activities such as working or studying, and supports people's health and comfort. © 2023 by the authors.
ABSTRACT
BACKGROUND AND AIM: The clinical presentation and severity of (MIS-C) presents a very low mortality in high-income countries. This research describes clinical characteristics of MIS-C in critically ill children in middleincome countries and factors associated with mortality and critical outcomes. METHOD(S): Observational cohort study in 14 (PICUs) in Colombia between April 2020 -January 2021. Patient age from one month to18 years, that met WHO requirements for MIS-C. RESULT(S): There were 78 children in this study. The median age was seven years (IQR 1-11), 18 % (14/78) were under one year old. 35 % of patients (29/78) were obese or overweight. 100 % had fever upon arrival to the clinic lasting at least five days (IQR 3.7-6). 70 % (55/78) of patients had diarrhea, and 87% (68/78) shock or systolic myocardial dysfunction (78 %), 35% (27/78) coronary aneurysms, and pericardial effusion in 36 %.There was a higher mortality rate compared to high in-come countries (9 % vs. 1.8 %;p=0.001). When assessing the group of patients who died, ferritin levels was above 500 ngr/mL (100 % vs. 45 %;p=0.012), as well as more cardiovascular complications (100 % vs. 54 %;p = 0.019). CONCLUSION(S): MIS-C in critically ill children living in a middle-income country has some clinical, laboratory, and echocardiographic characteristics, similar to high-income countries. Inflammatory response and cardiovascular involvement added to the difficulties in accessing the healthcare system in limited resources countries, could explain the greater mortality seen. Prospective studies are needed to compare the differences found in MIS-C outcomes between countries with different income.
ABSTRACT
The aim of this COVID-19 Practical Manual for the prevention, detection, control and surveillance of SARS-CoV-2 is to standardize and regulate the best strategy for the prevention and control of SARS-CoV-2 infections. All of this to provide better care quality to patients and their families/caregivers, and to promote a safe working environment for health personnel within the institution. The manual has been prepared with the aim of guiding health personnel in decision-making for the prevention, detection, control and surveillance of SARS-CoV-2 infections. This document describes various multidisciplinary care algorithms in different scenarios, considering the recommendations for isolation, use of personal protective equipment, transfer within various services in the hospital, admission to procedures and recommendations for healthcare personnel.
