Apnea testing is mandatory to confirm brain death; however, it is unsafe for patients who have substantial hypoxemia without ventilator support. We used a new modified apnea test without the need to disconnect the patient from the ventilator in the present study and compared the outcomes and complications of the new method to the widely used old method. ⋯ The modified apnea test produced better results in terms of O2 saturation, HR, and other clinical factors, while it does not require disconnection from the ventilator and repeated ABG assessment. Therefore, it can be used to successfully diagnose brain death in high-risk individuals suffering from severe hypoxia.

Given the high prevalence of hypertension in older adults, this study was conducted to identify the factors affecting the 5-year survival of older people with hypertension. ⋯ Multiple factors (such as age, gender, social support, lifestyle behaviors, and comorbidities including diabetes mellitus and renal function) might predict the 5-year survival of the elderly with hypertension. They should be considered in health-care package of these patients.

There is a lack of evidence on the link between mitral annular calcification (MAC) and coronary atherosclerotic diseases. The present investigation was undertaken to detect the clinical and prognostic value of MAC in coronary atherosclerotic diseases in patients who underwent coronary computed tomographic (CT) angiography. ⋯ The findings of the study revealed that MAC has no independent prognostic value in coronary atherosclerotic diseases evaluated by coronary CT angiography.

In this study, the relationship between involvement by COVID-19 and the recurrence of symptoms of rheumatoid arthritis (RA) was investigated. ⋯ The present study showed that infection with COVID-19 leads to the recurrence of joint symptoms in RA patients.

In the present study, we aimed to evaluate the effects of medroxyprogesterone on hospital short clinical outcomes and ABG parameters in patients with chronic obstructive pulmonary disease (COPD) exacerbation under treatments with noninvasive ventilation (NIV) treated with progesterone 15 mg in comparison with placebo. ⋯ Administration of medroxyprogesterone in patients with COPD exacerbation that required NIV was associated with significant improvements in blood pH, PCO2, dyspnea, and daily duration of NIV using after 3 and 5 days following hospitalization.
