From the severe acute respiratory syndrome coronavirus in 2003 to the severe acute respiratory syndrome coronavirus 2 in 2019, coronavirus has seriously threatened human health. Electromagnetic waves not only own high penetration and low pollution but also can physically resonate with the virus. Several studies have demonstrated that electromagnetic waves can inactivate viruses efficiently.

Department of Experimental Oncology, European Institute of Oncology, IRCCS, Milano, Italy.
Background: Randomised trials conducted from 2006 to 2021 indicated that vitamin D supplementation (VDS) was able to prevent severe COVID-19 and acute respiratory infections (ARI). However, larger randomised trials published in 2022 did not confirm the health benefits of VDS in COVID-19 patients.
Objective: To examine through a systematic review with meta-analysis the characteristics of randomised trials on VDS to COVID-19 patients and admission to intensive care unit (ICU), and of randomised trials on VDS for the prevention of ARI.
Cognitive impairment caused by compromised hepatic ketogenesis is prevented by endurance exercise.

Extensive research has demonstrated endurance exercise to be neuroprotective. Whether these neuroprotective benefits are mediated, in part, by hepatic ketone production remains unclear. To investigate the role of hepatic ketone production on brain health during exercise, healthy 6-month-old female rats underwent viral knockdown of the rate-limiting enzyme in the liver that catalyses the first reaction in ketogenesis: 3-hydroxymethylglutaryl-CoA synthase 2 (HMGCS2).

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been associated with significant cardiovascular complications, including myocardial infection and pulmonary embolism. This study aims to elucidate the relationship between the presence of SARS-CoV-2 RNA in the myocardium of the left ventricle and the levels of IgG and IgM antibodies against the SARS-CoV-2 virus in deceased COVID-19 patients. We conducted a post-mortem examination on 91 individuals who succumbed to COVID-19-related complications.

Background: Griscelli syndrome (GS) is a rare genetic disorder characterized by oculocutaneous albinism and variable immune dysfunction. Among three distinct types of GS, occurring due to different genetic mutations; GS type 1 presents with neurological manifestations, hemophagocytic lymphohistiocytosis (HLH) generally develops in GS type 2, and GS type 3 primarily exhibits oculocutaneous albinism. HLH, a life-threatening condition with excessive immune activation, may occur secondary to various triggers, including infections, and develop in different tissues, as well as in the testis, similar to Erdheim-Chester disease.
