Valve Surgery in a Low-Volume Center in a Low- and Middle-Income Country: A Retrospective Cross-Sectional Study.

Background: Valvular heart disease (VHD) has a significant prevalence and mortality rate with surgical intervention continuing to be a cornerstone of therapy. We aim to report the outcome of patients undergoing heart valve surgery (HVS) in a low-volume center (LVC) in a low- and middle-income country (LMIC).

Methods: A cross-sectional retrospective study was conducted at the Jordan University Hospital (JUH), a tertiary teaching hospital in a developing country, between April 2014 and December 2019.

Mathematical Modeling of Ion Quantum Tunneling Reveals Novel Properties of Voltage-Gated Channels and Quantum Aspects of Their Pathophysiology in Excitability-Related Disorders.

Voltage-gated channels are crucial in action potential initiation and propagation and there are many diseases and disorders related to them. Additionally, the classical mechanics are the main mechanics used to describe the function of the voltage-gated channels and their related abnormalities. However, the quantum mechanics should be considered to unravel new aspects in the voltage-gated channels and resolve the problems and challenges that classical mechanics cannot solve.

Surgical Outcomes in Patients With Preoperative Anemia Undergoing Colectomy for Colon Cancer.

Introduction: Preoperative anemia is relatively common in colon cancer patients; however, its impact on short-term surgical outcomes is not well established. The aim of our study was to evaluate short-term surgical outcomes in colon cancer patients with preoperative anemia undergoing colectomy.

Methods: We performed a 4-year analysis of the ACS-NSQIP and included all adult patients who underwent colectomy for colon cancer.

The impact of the Covid-19 pandemic on emergency surgery in a tertiary hospital in Jordan. A cross sectional study.

Background: Since the emergence of COVID-19 pandemic, governments around the world reacted by implementing curfews and sometimes nation-wide lockdowns intended to control the spread of the disease and help the already overwhelmed healthcare systems from imminent collapse. The Jordanian government was one of those countries that implemented a complete nation-wide lockdown which lasted for 3 months during the peak months of 2020. The aim of this study is to shed the light on the impact of this lockdown on the surgical emergency practice at a tertiary referral center in Amman, the capital of Jordan.
