RESUMEN
OBJECTIVE: We sought to investigate the disease outcomes and predictors of severe outcomes among children infected with the Delta variant of SARS-CoV-2 compared with pre-Delta strains. METHODS: Single-center retrospective cohort study in an emergency department located within an urban academic children's hospital. Patients included children (0-18 years) who tested positive for SARS-CoV-2. Main outcomes measured include need for hospital admission or COVID-directed therapies. RESULTS: There was a trend toward decreased hospital admission and no significant difference in the severity of outcomes in the Delta cohort relative to the pre-Delta cohort. The Delta cohort had lower odds of hospital admission (odds ratio [OR], 0.79; 95% confidence interval [CI], 0.51-1.23), but the result was not statistically significant. Logistic regression analyses showed that overall, age 1 to 4 years (OR, 2.35; 95% CI, 1.23-4.57) and public insurance (OR, 1.80, 95% CI, 1.08-3.01) were predictors of hospital admission. Within the Delta cohort, the presence of any comorbidity increased the odds of admission (OR, 2.52; 95% CI, 1.09-6.04). Black children had lower odds of admission than white children (overall OR, 0.53; 95% CI, 0.31-0.90; pre-Delta OR, 0.50; 95% CI, 0.26-0.95). CONCLUSIONS: The severity of measured disease outcomes was similar in pediatric patients when comparing children infected with the pre-Delta and Delta variants of SARS-CoV-2, even among children with comorbidities once adjusting for acuity.Ongoing research is essential to determine disease severity and risk for children with comorbidities because SARS-CoV-2 continues to mutate, including with Omicron subvariants.

OBJECTIVE: The objective of the current study was to identify risk factors for intrathoracic tuberculosis among children living in migrant populations in the Dominican Republic. DESIGN: Cross-sectional study. SETTING: Dominican Republic bateyes, economic migrant communities of Haitian origin. PARTICIPANTS: Children 18 months to 18 years of age. MAIN EXPOSURE: Unpasteurized milk consumption. OUTCOME MEASURES: Probable or possible intrathoracic tuberculosis. Probable intrathoracic tuberculosis was defined as any child with a tuberculin skin test >or=10 mm (or >5 mm in the presence of a known immunocompromising condition or household contact with intrathoracic tuberculosis) or malnutrition in the setting of an abnormal chest radiograph with features of tuberculosis or lymph node disease. The diagnosis of "possible intrathoracic tuberculosis" was assigned if an abnormal chest radiograph had features that did not meet the definition of "probable intrathoracic tuberculosis." RESULTS: Probable or possible tuberculosis was diagnosed in 83 (20.8%) of 400 children. Unpasteurized milk consumption was identified as an independent risk factor for intrathoracic tuberculosis (adjusted odds ratio, 3.2; 95% confidence interval: 1.4-7.4) even after adjusting for Bacille Calmette-Guérin vaccination, household size, tuberculosis contacts and age and under varying assumptions about children diagnosed with "possible" tuberculosis. CONCLUSIONS: Our data raise the possibility that the high prevalence of tuberculosis in the Dominican Republic bateyes may be attributable to Mycobacterium bovis rather than Mycobacterium tuberculosis infection.
