A pandemic is still present as of May 2020. In addition to causing pneumonia, SARS-CoV-2 may induce a direct damage to the heart, causing myocarditis, with significant impairment of cardiac contractility, and/or pericarditis. Elderly patients and those with cardiovascular risk factors, such as hypertension and diabetes mellitus, are at increased risk of heart complications from COVID-19. In this review, we focused on the correlation between COVID-19 infection and the high sensitivity troponin T and I, and their significance in the development of myocarditis. Data emerging from the studies so far conducted indicate that a high value of high-sensitivity troponin represents a negative prognostic indicator when associated with heart damage on an infectious-inflammatory basis (i.e. myopericarditis). We should identify a safe and clear diagnostic algorithm, possibly combining patient clinical history, troponin levels and cardiac ultrasound findings that could help us in the prediction of myopericarditis. The wildfire allied environmental pollution is highly toxic and can cause significant wide-ranging damage to the regional environment, weather conditions, and it can facilitate the transmission of microorganisms and diseases. The present study aims to investigate the effect of wildfire allied pollutants, particulate matter (PM-2.5 μm), and carbon monoxide (CO) on the dynamics of daily cases and deaths due to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in San Francisco, USA. For this study, we selected San Francisco, one of the regions affected by the wildfires allied pollution in California, USA. The data on the COVID-19 pandemic in San Francisco, including daily new cases and new deaths were recorded from Worldometer Web. The daily environmental pollutants particulate matter (PM-2.5 μm) and carbon monoxide (CO) were recorded from the metrological web "BAAQMD". The daily cases, deaths, particulate matter (PM-2.5 μm) and carbon monoxide were documented from the date of the occurrhs increased by 5%, 9.3% and 5.3%, respectively. On the other hand, CO and daily deaths had no significant relationship. The wildfire allied pollutants, particulate matter PM-2.5μm and CO have a positive association with an increased number of SARS-COV-2 daily cases, cumulative cases and cumulative deaths in San Francisco. The metrological, disaster management and health officials must implement the necessary policies and assist in planning to minimize the wildfire incidences, environmental pollution and COVID-19 pandemic both at regional and international levels.

SARS-CoV-2 is currently affecting millions of humans worldwide, thus contributing to the COVID-19 pandemic. Thromboembolic events have a higher incidence among patients with COVID-19, but there are few reports on the relationship between the prognosis of COVID-19 patients and thromboembolic events. The objectives of this meta-analysis were to explore the relationship between the prognosis of COVID-19 patients and thromboembolic events. Medline (PubMed), the Web of Science, Embase, and the Cochrane Library were searched for case-control studies that included data on vein thrombosis in patients with COVID-19 and were published in English, between January 1 and July 25, 2020. According to the inclusion and exclusion criteria, the included data were confirmed, the prognoses of patients with and without concurrent thromboembolic events were compared, and the odds ratio (OR) was used as the effect size. Eighteen studies (2,030 patients) were included. Thromboembolic events complicated a total of 609 COVID-19 patients. The combined OR of the mortality of COVID-19 patients with thromboembolic events was 1.93 (95% CI 1.13-3.27), that of ICU treatment rate was 2.63 (95% CI 1.49-4.67), and that of treatment with invasive mechanical ventilation was 3.14 (95% CI 1.97-5.02). As compared with COVID-19 patients with and without thromboembolism, the mortality, ICU treatment rate, and invasive mechanical ventilation treatment rate of COVID-19 patients with thromboembolism were found to be increased significantly, and the prognosis was worse. As compared with COVID-19 patients with and without thromboembolism, the mortality, ICU treatment rate, and invasive mechanical ventilation treatment rate of COVID-19 patients with thromboembolism were found to be increased significantly, and the prognosis was worse.
