Tocilizumab is useful for coronavirus disease 2019 patients: the key point is timing.
In coronavirus disease 2019, a rapidly progressive inflammatory process is considered to be the main cause of organ damage and mortality. Therefore, the importance of anti-inflammatory treatments such as tocilizumab is increasing. ⋯ The results showed that tocilizumab is an effective treatment option for coronavirus disease 2019 disease and reduces mortality, but the key point is timing.

Association between handgrip strength and body composition, physical fitness, and biomarkers in postmenopausal women with metabolic syndrome.
This study examined the association between handgrip strength and body composition, physical fitness, and biomarkers in postmenopausal women with metabolic syndrome. ⋯ This study showed that handgrip strength was predictive of fat-free mass, blood pressure, and upper limb strength performance.

COVID-19 infection rates among transportation and metal workers.
The aim of this study was to compare the workers in the metal and transportation sectors in terms of COVID-19 infection frequency and to examine and establish links between infection frequency and the workplace working conditions. ⋯ The results emphasized that the characteristics of jobs, physical proximity during job hours, the use of protective equipment, and size of the workplaces should be considered as reasons for different infection risks in different sectors.

Clinical and radiological characteristics of pulmonary actinomycosis mimicking lung malignancy.
Pulmonary actinomycosis, clinically and radiologically, mimics abscess, tuberculosis, and lung malignancy, resulting in misdiagnosis or delay in diagnosis. In this study, we analyzed the clinicoradiological features of pulmonary actinomycosis, the presence of any differences between clinical prediagnosis and radiological diagnosis, and whether imaging modalities help distinguish pulmonary actinomycosis from lung cancer. ⋯ Pulmonary actinomycosis shows high metabolic uptake in positron-emission tomography/computed tomography, and this may mislead clinicians for a diagnosis of malignancy. Our results suggest that positron-emission tomography/computed tomography does not help distinguish pulmonary actinomycosis from lung malignancy and does not provide a clear diagnostic benefit to the clinician, so pathological diagnosis is necessary.

The prognostic value of the CHA2DS2-VASc score in coronary collateral circulation and long-term mortality in coronary artery disease.
The CHA2DS2-VASc score is used to determine thromboembolic risk in cases of atrial fibrillation. The predictive value of this score in predicting coronary collateral circulation in chronic total occlusion is unknown. ⋯ The CHA2DS2-VASc score is closely related to coronary collateral development and predicts mortality in patients with chronic total occlusion.
