Low levels of vitamin D are known to increase cardiovascular mortality due to different risks. We aimed to examine whether low vitamin D levels in children and adolescents cause ventricular repolarization changes. ⋯ Decline in vitamin D levels causes ventricular repolarization anomaly. As the decrease in vitamin D levels deepens, repolarization times become longer. These results could indicate that decrease in vitamin D levels can increase sensitivity to ventricular arrhythmias (Tab. 3, Ref. 45).

Coronavirus disease 2019 (COVID-19) has become a serious public health problem for 183 out of 197 countries in the world. Understanding the routes and pathogenesis of the coronavirus is important and it is considered that the studies on host cell receptor Angiotensin Converting Enzyme 2 (ACE2) may be valuable for the treatment and prevention of the disease. ⋯ In view of the fact that the mouth and nose have higher number of ACE2 expressed cells, they serve as a gateway for the virus to enter. Thus, blocking the gate could be a good choice to reduce or even prevent the transmission. Small interfering RNAs (siRNAs) are double-stranded RNA molecules and could be designed easily and directed against many strains of a virus. Due to their features, siRNAs can provide a potential strategy to interfere with the replication of viral diseases. We think that since oral and nasal epithelial cells are relatively easily accessible it may allow to develop siRNA molecules to inhibit SARS-CoV-2 already at the entry where it continues to replicate for a period (Fig. 1, Ref. 50).

The objective was to find out risk factors indicating the patients directly to selective coronarography (SCG) to avoid unnecessary non-invasive testing and in their absence to asses low cardiovascular risk and faster inclusion on the waiting list. ⋯ In our analysis, patients with DM and poorly managed chronic kidney disease/mineral bone disease were the riskiest subset of the patients with a positive SCG finding (Tab. 4, Fig. 2, Ref. 30).

Arthroscopic Latarjet surgery is a technique developed to minimize invasive surgical treatment of anterior shoulder instability. However, compared to an open Latarjet operation, it is considered more technically demanding. The aim of our study was to assess its mid-term success rate in the hands of a surgeon with sufficient experience. ⋯ Our results demonstrated that when in the hands of experienced surgeon, the arthroscopic Latarjet surgery is an effective surgical method with a low incidence of complications and excellent mid-term clinical outcomes (Fig. 17, Ref. 25).

The present study aims to report the incidence of colorectal cancer patients under 50 years of age and to compare its aggressiveness with colorectal cancer patients over 50 years of age. ⋯ The incidence of colorectal cancer has increased at younger ages and has a more aggressive course. Screening programs should be modified (Tab. 4, Fig. 2, Ref. 45).
