We performed this meta-analysis evaluating the efficacy of chronotherapy of hypertension with angiotensin receptor blockers (ARBs). ⋯ Bedtime dosing with ARBs is more effective in lowering sleep-time BP than awakening dosing in patients with essential hypertension, suggesting a utilization of chronotherapy of hypertension with ARBs to reduce sleep-time high BP. Larger multi-ethnic studies are needed to investigate the efficacy of chronotherapy of hypertension.

Review Case Reports
Endobronchial Lipoma: Case Report and Literature Review.
Endobronchial lipomas are rare benign tumors that can cause bronchial obstruction resulting in significant symptoms and post-obstructive parenchymal damage. Accurate diagnosis and treatment are essential to avoid unnecessary morbidity and mortality in these patients. ⋯ Notably, in cases reported since 2010, 72.7% of cases were managed bronchoscopically. Recurrence rates are low following both bronchoscopic and surgical resection.

Coronavirus Disease 2019 (COVID-19) is an infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus. SARS-CoV-2 caused COVID-19 has reached a pandemic level. COVID-19 can significantly affect patients' cardiovascular systems. ⋯ Associated with a high inflammatory burden related to cytokine release, COVID-19 can induce vascular inflammation, acute myocardial injury, myocarditis, arrhythmias, venous thromboembolism, metabolic syndrome and Kawasaki disease. Understanding the effects of COVID-19 on the cardiovascular system is essential for providing comprehensive medical care for cardiac and/or COVID-19 patients. We hereby review the literature on COVID-19 regarding cardiovascular virus involvement.

Potassium is the most important intracellular cation and the kidneys play a pivotal role in potassium homeostasis. Potassium disorder is a common electrolyte abnormality and it increases the risk of death from any cause, particularly cardiovascular events. Hyperkalemia is a common electrolyte abnormality encountered post organ transplantation. ⋯ However, the long-term efficacy and safety of fludrocortisone for management of hyperkalemia in organ transplant recipients remains unknown. This review discusses potassium homeostasis, including the role of the kidneys, and focuses on calcineurin inhibitor-induced hyperkalemia and on the under-appreciated role of thiazide-type diuretic use in management of hyperkalemia and hypertension. We present an illustrative case of post-transplantation hyperkalemia and hypertension with relevant literature.

Review Case Reports
An Unusual Presentation of Aggressive Primary Invasive Adenocarcinoma of Lung.
Bilateral diffuse infiltrates on chest imaging can present a diagnostic challenge due to a broader differential diagnosis which includes pulmonary and non-pulmonary causes. Malignancy is generally not considered under differential diagnosis at the time of initial presentation. ⋯ Our case is unique in regards to its acute presentation, rapid progression to respiratory failure, ultimately leading to the demise of the patient. This indicates the aggressive nature of this malignancy and its variable presentation, like male gender and young age, thus emphasizing the importance of entertaining malignancy in such presentations, especially if there is no response to conventional antibiotic therapy.
