Prognostic Impact of Red Cell Distribution Width on the Development of Contrast-Induced Nephropathy, Major Adverse Cardiac Events, and Mortality in Coronary Artery Disease Patients Undergoing Percutaneous Coronary Intervention.

Red cell distribution width (RDW) serves as an independent predictor towards the prognosis of coronary artery disease (CAD) in patients undergoing percutaneous coronary intervention (PCI). A systematic search of databases such as PubMed, Embase, Web of Science, and Cochrane library was performed on October 10th, 2019, to elaborate the relationship between RDW and in hospital and long term follow up, all-cause and cardiovascular mortality, major adverse cardiac events (MACE) and development of contrast-induced nephropathy (CIN) in patients with CAD undergoing PCI. Twenty-one studies qualified this strict selection criterion (number of patients = 56,425): one study was prospective, and the rest were retrospective cohorts.

A systematic review and meta-analysis of impact of baseline thrombocytopenia on cardiovascular outcomes and mortality in patients undergoing percutaneous coronary intervention.

Background: Thrombocytopenia (TP) is associated with higher incidence of bleeding in the setting of percutaneous coronary intervention (PCI) leading to increased morbidity and mortality. Herein, we report a meta-analysis evaluating the effects of baseline thrombocytopenia (bTP) on cardiovascular outcomes in patients undergoing PCI.

Methods: Literature search was performed using PubMed, Embase, Cochrane library and clinicaltrials.

Obstructive sleep apnea and peripheral vascular disease: a systematic review based on current literature.

Introduction: Obstructive sleep apnea (OSA) is an established risk factor for poor cardiovascular outcomes and coronary artery disease, but its influence on the development of peripheral artery disease (PAD) is not well established. The aim of our study was to understand the mutual prevalence of OSA and PAD and any reported statistical association between the two conditions.

Methods: PubMed, Ovid Embase, Web of Science, Cochrane library and clinicaltrials.

Impact of Acquired Thrombocytopenia on Cardiovascular Outcomes in Patients With Coronary Artery Disease Undergoing Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis.

Background: Acquired thrombocytopenia (aTP) is associated with a high frequency of bleeding and ischemic complications in patients undergoing percutaneous coronary intervention (PCI). Herein, we report a meta-analysis evaluating the adverse effects of aTP on cardiovascular outcomes and mortality post-PCI.

Methods: A literature search was performed using PubMed, Embase, Cochrane and, clinicaltrials.

Zinner Syndrome Unmasked by Workup for Renal Colic and Uncontrolled Hypertension.

Zinner syndrome is a rare hereditary disorder of the mesonephric duct. The triad of the absence of one kidney, ipsilateral cystic dilatation of the seminal vesicle, and ejaculatory duct obstruction makes the diagnosis. Mostly, it is asymptomatic.

Percutaneous coronary intervention for chronic total occlusion in patients aged <75 years versus ≥75 years: a systematic review.

: To examine the effect of age on procedural and clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) lesions. : Literature search was conducted across PubMed, Google Scholar and Web of science, databases till March 2019. : Seven studies including 7671 patients with an overall follow-up period of 1.

Small Intestinal Tumors: A Rare Case of Tubulovillous Adenoma in Duodenum.

The small intestine is a relatively privileged organ; primary tumors are uncommon among malignancies of the gastrointestinal tract, with an average annual incidence rate of 9.9 per million people. Among these uncommon tumors, duodenal tumors are even rarer with an average incidence rate of 0.

Team-based Learning and the Analytical Skills of Medical Students as a Consequence of Increased Problem Difficulty.

Problem-based learning is a learner-centered teaching method, which uses real-world scenarios to promote student learning of concepts and principles. The aim of our study is to analyze the consequence of increased problem difficulty on team-based learning and the analytical skills of medical students. In our prospective descriptive study, two problem-based learning scenarios prepared on the topic of hypercortisolism were given to 197 students in two successive sessions.

Special considerations for the treatment of multiple myeloma according to advanced age, comorbidities, frailty and organ dysfunction.

Multiple Myeloma (MM) is primarily a disease of old age with a median age of sixty-nine years at diagnosis. The development of novel therapies for induction and use of autologous stem cell transplantation has resulted in improved clinical outcomes and better quality of life for MM patients. Elderly patients, comprising the majority of MM population, have a higher incidence of age-related comorbidities, frailty and organ dysfunction which complicates the coordination of treatment and limits the selection of therapies.

Presentation of a Rare Malignancy: Leiomyosarcoma of the Prostate.

Prostatic leiomyosarcoma is an aggressive malignancy with a high risk of metastasis and a poor prognosis that poses unique diagnostic and treatment challenges.
