The Evolution of Renal Denervation for the Treatment of Hypertension: Insights from Trials and Prospects for Clinical Practice.

Hypertension affects 1.3 billion adults globally, with severe health implications if left untreated. Despite efforts, research suggests only a fraction achieve adequate control.

Digestive system involvement and clinical outcomes among COVID-19 patients: A retrospective cohort study from Qatar.

Background: Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 virus most commonly presents with respiratory symptoms. While gastrointestinal (GI) manifestations either at presentation or during hospitalization are also common, their impact on clinical outcomes is controversial. Some studies have described worse outcomes in COVID-19 patients with GI symptoms, while others have shown either no association or a protective effect.

Frequency of Acute Kidney Injury in Patient Receiving Piperacillin - Tazobactam: A Hospital-based Study from Qatar.

Background: several studies have been reported piperacillin-tazobactam (TAZ / PIPC)-associated AKI with various frequencies. The aim of this study was to determine the frequency of TAZ/PIPC- associated AKI among our patients and to identify the risk factors for this clinical entity.

Methods: this retrospective cross-sectional study was conducted at Hamad General Hospital; it involved adult patients who were admitted from January 2017 to December 2017.

Myopericarditis Presenting as Acute ST-Elevation Myocardial Infarction with Atrioventricular Dissociation.

Myopericarditis, which is an inflammatory process involving the myocardium and pericardium, is not a rare condition encountered in cardiac emergencies. Rarely though, it can give an acute myocardial infarction picture on electrocardiogram (ECG), leading to urgent angiography. More rarely, it can be associated with atrioventricular (AV) dissociation, which is a condition of dyssynchrony of electrical activity between atria and ventricles.

The Role of Anticoagulation in Post-COVID-19 Concomitant Stroke, Myocardial Infarction, and Left Ventricular Thrombus: A Case Report.

BACKGROUND Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the lungs but can involve any organ. The medical community is struggling to cope with the critical illness associated with the disease. On top of that, patients who have recovered from COVID-19 have presented with complications such as thrombotic episodes in various organs both during and after being infected with SARS-CoV-2.

Optic neuropathy as a presenting feature of vitamin B-12 deficiency: A systematic review of literature and a case report.

Introduction: Vitamin B12 (VitB12) deficiency rarely manifests with visual symptoms. Optic nerve damage in VitB12 deficiency is thought to be via degeneration. However, optic neuritis, though infrequent, has been reported secondary to VitB12 deficiency.
