ASSOCIATIONS BETWEEN AMBIENT FINE PARTICULATE MATTER AND CHILD RESPIRATORY INFECTION: THE ROLE OF PARTICULATE MATTER SOURCE COMPOSITION IN DHAKA, BANGLADESH.
Short-term increases in ambient air pollution were associated with a rise in the incidence of pneumonia in children, according to a large, community-based study in Bangladesh.
Of 28,089 clinic visits included in this analysis, 17,219 resulted in a pneumonia diagnosis and 10,870 resulted in an upper respiratory infection diagnosis.

EFFECT OF AMOXICILLIN DOSE AND TREATMENT DURATION ON THE NEED FOR ANTIBIOTIC RE-TREATMENT IN CHILDREN WITH COMMUNITY-ACQUIRED PNEUMONIA – THE CAP-IT RANDOMIZED CLINICAL TRIAL
In this 2 × 2 factorial randomized clinical trial of 814 children requiring amoxicillin for community-acquired pneumonia at hospital discharge, antibiotic re-treatment within 28 days occurred in 12.6% vs 12.4% of those randomized to lower vs higher doses, and in 12.5% vs 12.5% of those randomized to 3-day vs 7-day amoxicillin duration. Among children with community-acquired pneumonia, further outpatient treatment with oral amoxicillin at a dose of 35 to 50 mg/kg per day was noninferior to a dose of 70 to 90 mg/kg per day and 3 days was noninferior to 7 days with regard to the need for later antibiotic re-treatment.

COVID-19 TIED TO A WIDE RANGE OF ECG FINDINGS
COVID-19 infection has a number of cardiac manifestations that include myocardial infarction, myocarditis and various patterns of changes observed on electrocardiograms. In a new report in Cardiac Electrophysiology Clinics discusses some of the reported ECG changes, such as abnormal QRS axis in nearly 20% of patients, conduction abnormalities in approximately 20%, atrioventricular block in about 2.5%, and premature beats in nearly 10% of patients.

RISK OF SARS-COV-2 TRANSMISSION FROM ON-FIELD PLAYER CONTACTS IN AMATEUR, YOUTH AND PROFESSIONAL FOOTBALL (SOCCER)
Researchers investigated the risk of transmission among potentially infectious SARS-CoV-2-positive football players while participating in training or matches at amateur, youth and professional levels. Out of 1247 identified football matches and training sessions, 104 cases (38 training sessions, 66 matches) with 165 potentially infectious players were detected. Follow-up PCR testing at the professional level (44 cases) revealed no transmission. Study concludes that on-field transmission risk of SARS-CoV-2 in football is very low.
