Clinical characteristics and risk factors associated with COVID-19 mortality in a non-Intensive Care Unit.

Introduction: The Coronavirus disease 2019 caused by a new Coronavirus (SARS-CoV-2) throughout the pandemic period has been characterised by a wide spectrum of clinical manifestations, courses, and outcomes. In particular, most patients with severe or critical symptoms re-quired hospitalization. The demographic and clinical characteristics of patients upon admission to the hospital, as well as pre-existing medical conditions, seem to have affected the clinical out-come.

Is telomere length in buccal or salivary cells a useful biomarker of exposure to air pollution? A review.

Telomeres are repetitive DNA-protein sequences located at the end of chromosomes and play an essential role in preserving information in our genome by protecting against end-to-end fusion, nucleolytic degradation, breakage, and inappropriate recombination. The telomeres shorten with aging and this process can be affected by oxidative stress and inflammation. Environmental and occupational factors may contribute to telomere length (TL) shortening, as demonstrated by an increasing number of studies.

Fatal septicemia and meningitis complicated by fungemia: a case report.

is a Gram-positive bacteria and etiological agent of listeriosis. It has the ability to colonize the intestinal lumen and cross the intestinal, blood-brain, and placental barriers, leading to invasive listeriosis responsible for septicemia and meningitis in subjects at risk such as patients with diabetes mellitus, the elderly, and immunocompromised individuals and, for maternal-neonatal infection in pregnant women. We report a rare case of septicemia and meningitis complicated by fungemia on a patient with a history of type 2 diabetes mellitus, hypothyroidism, hypertension, chronic kidney failure, chronic ischemic vascular encephalopathy, and atrial fibrillation.

The Role of ABO Blood Type in Patients with SARS-CoV-2 Infection: A Systematic Review.
