We performed a time series analysis in Vienna, Austria, investigating the temporal association between daily air pollution (nitrogen dioxide, NO2 and particulate matter smaller than 10 µm, PM10) concentration and risk of coronavirus disease 2019 (COVID-19) infection and death. Data covering about 2 months (March-April 2020) were retrieved from public databases. Infection risk was defined as the ratio between infected and infectious. ⋯ That association was significant for the irritant gas (p = 0.012) but not for particles (p = 0.22). Pollutants did not affect COVID-19-related mortality. The study findings might have wider implications on an interaction between air pollution and infectious agents.

Multicenter Study Meta AnalysisThe neutrophil to lymphocyte ratio is an independent predictor for severe COVID-19 : Evidence from a multicenter case-control study and meta-analyses.
The aim of this study was to determine whether the neutrophil to lymphocyte ratio (NLR) can predict severe Coronavirus disease 2019 (COVID-19). ⋯ Based on a multicenter case-control study and a meta-analysis, we found that the initial NLR was a great predictor of severe COVID-19.

Randomized Controlled TrialSafety and immunogenicity of an mRNA-lipid nanoparticle vaccine candidate against SARS-CoV-2 : A phase 1 randomized clinical trial.
We used the RNActive® technology platform (CureVac N.V., Tübingen, Germany) to prepare CVnCoV, a COVID-19 vaccine containing sequence-optimized mRNA coding for a stabilized form of SARS-CoV‑2 spike (S) protein encapsulated in lipid nanoparticles (LNP). ⋯ In this study 2 CVnCoV doses were safe, with acceptable reactogenicity and 12 μg dosages elicited levels of immune responses that overlapped those observed in convalescent sera.

ReviewAlterations of the male and female reproductive systems induced by COVID-19.
A variety of pneumonia cases of unknown cause emerged in China in December 2019. A new virus belonging to the Coronaviridae family, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19). Within a few days, COVID-19 became a pandemic disease. ⋯ Moreover, it was noted that there was viral genetic material in the semen and an increase in the serum concentration of luteinizing hormone (LH) in men and women, which could cause hypogonadism. Thus, we conclude that there is the possibility of infection and malfunction in the reproductive organs as well as the plausibility of sexual transmission of this disease. Further analysis must be carried out to prove the effects of COVID-19 on the human reproductive systems.

Impact of COVID-19 pandemic on outpatient appointments of rheumatic patients in a non-outbreak area of China.
Coronavirus disease 2019 (COVID-19) infection has caused huge impacts on all of people's lives and health systems. In response to the COVID-19 pandemic, China was the first country to impose lockdown. We aimed to study the influence of COVID-19 on the outpatient visits of rheumatic patients in a non-outbreak area of China. ⋯ The impact on the western hospital was greater than that on the Chinese medicine hospital, and the impact on the back-up designated hospitals for COVID-19 was the greatest. Online appointment can reduce the risk of infection in outpatients, but not completely solve the follow-up problem of rheumatic patients. Telemedicine provides a new solution for both management of rheumatic patients and control of COVID-19.
