Aims: Pre-existing conditions, such as age, hypertension, obesity, and diabetes, constitute known risk factors for severe COVID-19. However, the impact of prediabetes mellitus (PDM) on COVID-19 severity is less clear. This study aimed to evaluate the influence of PDM in the acute and long-term phases of COVID-19.
Materials And Methods: We compared inflammatory mediators, laboratory and clinical parameters and symptoms in COVID-19 patients with prediabetes (PDM) and without diabetes (NDM) during the acute phase of infection and at three months post-hospitalization.
Results: Patients with PDM had longer hospital stays and required intensive care unit admission more frequently than NDM. Upon hospitalization, PDM patients exhibited higher serum levels of interleukin 6 (IL-6), which is related to reduced partial pressure of oxygen (PaO) in arterial blood, oxygen saturation (SpO) and increased COVID-19 severity. However, at three months after discharge, those with PDM did not exhibit significant alterations in laboratory parameters or residual symptoms; however, PDM was observed to influence the profile of reported symptoms.
Conclusions: PDM seems to be associated with increased risk of severe COVID-19, as well as higher serum levels of IL-6, which may constitute a potential biomarker of severe COVID-19 risk in affected patients. Furthermore, while PDM correlated with more severe acute-phase COVID-19, no long-term worsening of sequelae was observed.

The rapid development and deployment of mRNA and non-mRNA COVID-19 vaccines have played a pivotal role in mitigating the global pandemic. Despite their success in reducing severe disease outcomes, emerging concerns about cardiovascular complications have raised questions regarding their safety. This systematic review critically evaluates the evidence on the cardiovascular effects of COVID-19 vaccines, assessing both their protective and adverse impacts, while considering the challenges posed by the limited availability of randomized controlled trial (RCT) data on these rare adverse events.

Background: The COVID-19 pandemic was associated with increased psychological distress and psychiatric service usage in Australia. Previous research into the first few months of the pandemic found severe inequality in telehealth psychiatry but no change in inequality for psychiatry service usage overall. However, it is unknown how inequality evolved over the remainder of the pandemic, as extended lockdowns continued in major Australian cities.

Rhinolophus bats have been identified as natural reservoirs for viruses with global health implications, including severe acute respiratory syndrome-related coronaviruses (SARSr-CoV) and swine acute diarrhoea syndrome-related coronavirus (SADSr-CoV). In this study, we characterised the individual viromes of 603 bats to systematically investigate the diversity, abundance and geographic distribution of viral communities within R. affinis, R.

Background: For a long time, the penalty of imprisonment has been studied and criticized as ineffective in achieving the goals of resocialization and rehabilitation of offenders, and studies have associated incarceration with increased prevalence of disease. In response to the COVID-19 pandemic, the World Health Organization recommended decarceration as a prevention measure. The aim of this review was to analyze the effectiveness of non-exposure to incarceration in preventing COVID-19 and mitigating associated events.
