Body composition and metabolic consequences of antibiotics most frequently administered to newborns in intensive care units: an experimental study in healthy newborn rats.

Introduction: The increasing overuse of antibiotics in recent years has led to antibiotics being the most prescribed drugs for pediatric patients, and 72% of patients in the neonatal intensive care unit are treated with antibiotics. One effect of antibiotic use is the alteration of the microbiota, which is associated with metabolic disorders, including obesity.

Methods: This experimental study in newborn rats compared the administration of ampicillin/meropenem (Access/Watch groups) at 100/10 μg/g every 12 h, cefotaxime 200 μg/g every 24 h (Watch group), and amikacin 15 μg/g every 24 h (Access group) versus saline solution as the control.

Bases for a treatment of cutaneous leishmaniasis with moderate hyperthermia.

Introduction: Regional hyperthermia at between 38 and 39.5 °C has been used to treat inflammatory processes and, occasionally, skin infections. In areas where leishmaniasis is endemic, hot compresses are applied as anti-parasitic treatment.

COVID-19 patients with increasing age experience differential time to initial medical care and severity of symptoms.

We conducted a retrospective observational study in patients with laboratory-confirmed coronavirus disease (COVID-19) who received medical care in 688 COVID-19 ambulatory units and hospitals in Mexico City between 24 February 2020 and 24 December 2020, to study if the elderly seek medical care later than younger patients and their severity of symptoms at initial medical evaluation. Patients were categorised into eight groups (<20, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79 and ≥80 years). Symptoms at initial evaluation were classified according to a previously validated classification into respiratory and non-respiratory symptoms.

Breastfeeding and COVID-19.

The coronavirus disease 2019 (COVID-19) pandemic has affected all dimensions of health care, including exclusive breastfeeding assurance and its promotion. The risk of contagion and the consequences of the pandemic have raised concerns among future mothers or in those who are already breastfeeding due to the risk of possible transmission of the virus through breast milk, although active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has not yet been detected in breast milk. The fear of contagion has favored mother-child isolation policies.
