Why Children Seem to Be Less Affected By the Coronavirus

If there was one glimmer of hope among the alarming number of cases of COVID-19 in the past few months, it was that young children seemed to avoid more serious illness. That trend, which doctors in China first reported, seems to be holding true in the US as well. In the latest Morbidity and Mortality Weekly Report report released today by the Centers for Disease Control (CDC), scientists say that compared to adults, children under the age of 18 are less likely to experience the typical symptoms of infection, including fever, cough and difficulty breathing, and are also less likely to need hospitalization and less likely to die of COVID-19. That’s an unusual bit of good news for a respiratory disease, since viruses like influenza often strike the very young and the very old more aggressively, given their more vulnerable immune systems. “I can’t think of another situation in which a respiratory infection only affects adults so severely,” says Dr. Yvonne Maldonado, professor of pediatrics at Stanford University School of Medicine and chair of the committee on infectious diseases at the American Academy of Pediatrics. “This is not common at all; we just don’t know what is going on here.” “The fact is that we are not seeing preponderance of severe [COVID-19] disease in young children, which is distinct from influenza,” says Dr. Kristin Moffitt, an assistant professor pediatrics at Harvard Medical School and a pediatric infecti...

Authors: Shi YQ, Qi WF, Kong CY Abstract Rheumatoid arthritis (RA), which normally manifests as a multi‑joint inflammatory reaction, is a common immunological disease in clinical practice. However, the pathogenesis of RA has not yet been fully elucidated. Rituximab (RTX) is an effective drug in the treatment of RA, however its therapeutic efficacy and mechanism of action require further investigation. Thus, the present study aimed to screen the candidate key regulatory genes and explain the potential mechanisms of RA. Gene chips of RA and normal joint tissues were analyzed and, gene chips of RTX before and after ...

Authors: Park YG, Choi J, Seol JW Abstract During pregnancy, the uterus undergoes intense neovascularization and vascular remodeling to supply oxygen and nutrients to the embryo. During this period, progesterone secreted from the ovary has effects on vascular remodeling in the endometrium and interacts with angiogenic factors. However, the exact mechanism of uterine vascular remodeling during pregnancy is poorly understood. Therefore, the aim of the present study was to investigate the association between angiopoietin-2 (Ang-2), one of the angiopoietins, and intrauterine vessel remodeling during pregnancy, and to d...

In conclusion, TCGA classification based on a Chinese population is the same as TCGA typing based on a European population in terms of proportion and clinical characteristics, but there are differences in gene amplification and gene mutation. ACRG molecular classification could be performed by IHC analysis and may be a valuable independent prognostic marker for patients with GC. PMID: 32468041 [PubMed - as supplied by publisher]

This article proposes strategies to ensure the ongoing effectiveness, efficiency and engagement of lectures transitioning from face-to-face to online delivery. Cognitive learning theory, strategies to promote learner engagement and minimise distraction, and examples of software affordances to support active learning during the lecture are proposed. This enables lecturers to navigate the challenges of lecturing in an online environment and plan fruitful online lectures during this disruptive time. These suggestions will therefore enable HPE to better meet the existing and future needs of regional, rural and remote learners ...

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has spread rapidly across the globe. In contrast to initial reports, recent studies suggest that children are just as likely as adults to become infected with the virus but have fewer symptoms and less severe disease. In this review, we summarize the epidemiologic and clinical features of children infected with SARS-CoV-2 reported in pediatric case series to date. We also summarize the perinatal outcomes of neonates born to women infected with SARS-CoV-2 in pregnancy. We found 11 case series including a total of 333 infants and children. Overal...
