Radiological Characteristics of Patients Infected with Coronavirus Disease-2019 (COVID-19): A Retrospective, Observational Study from Iran

Abstract

Background: Management of Covid-19 patients is key to control the pandemic. In this line, access to chest Computed Tomography (CT) scan findings and investigating changes during initial diagnosis until recovery is of crucial importance. Objectives: The present study aimed to investigate the chest CT-scan findings of patients with a definitive diagnosis of Covid-19 in Guilan, Iran. Methods: In this retrospective study, 1000 patients with a definitive diagnosis of Covid-19, from 20 April to 30 July 2020, were enrolled. Their first and follow-up chest CT-scans were obtained. Total lung involvement was determined by the number of lobes involved and by scoring 0 to 5 for each lobe (5 lobes, lowest score: 0, and highest score: 25). Results: In this study, three CT-scans of all 1000 patients were studied. Patients were classified into 4 stages according to their hospitalization duration (ranging from 0 to 30 days): stage 1 or primary (0 to 7 days): ground-glass opacities (n = 178 or 89%), stage 2 or progressive (8 to 15 days): increased crazy-paving pattern (n = 89 or 44.5%), stage 3 or peak involvement (16 to 22 days): consolidation (n = 78 or 89%), and stage 4 or decreased pulmonary involvement severity (greater than 23 Day): the gradual resolution of consolidation (n = 178 or 89%). Conclusions: Chest CT-scan findings revealed that patients with Covid-19 had a high rate of pulmonary involvement, on average, for the first 15 days, which then declined.

Evaluation of Newborns Diagnosed with COVID-19: A Single-Center Experience

“…Newborns with bronchopulmonary dysplasia, prematurity, severe malnutrition, immunodeficiency, and respiratory disorders also need more careful COVID-19 exposure and disease management, as do newborns with congenital heart disease. 13 14…”

“…Previous studies reported that infants had less severe symptoms, a milder clinical course, and rarely need for hospitalization. 13 A review of clinical characteristics of COVID-19 showed that 92% of infants and children were asymptomatic. Fever, cough, respiratory distress, feeding intolerance, vomiting, diarrhea, cyanosis, and tachycardia are the most common clinical symptoms in the neonatal age group.…”

Análisis desde la academia del impacto en las dimensiones salud y economía por el covid-19 en el Ecuador

Panahi et al (2020), afirma que las mujeres tienen mayor riesgo de presentar complicaciones en el embarazo, al infectarse con el virus Sars CoV 2, como dificultad respiratoria y parto prematuro, llegando inclusive a la muerte materna. En el estudio realizado por (Cupul-Uicab et al, 2021) se observó que en las gestantes con COVID-19, presentaron mayor ingresos a cuidados intensivos y uso de ventilación mecánica invasiva.…”

Breastfeeding during COVID Pandemic

“…COVID-19 is an infectious disease that was declared a public health emergency of international concern by the WHO [54]. Their main concern is whether breastfeeding by mothers infected with COVID-19 is safe, and whether the virus or antibodies can be transmitted from mother to baby through milk [55].…”
