Frequency and Predictors of Acute Kidney Injury in Patients With Acute Coronary Syndrome in a Tertiary Care Hospital: A Retrospective Study.

Introduction Acute kidney injury (AKI) is a complex condition marked by rapid deterioration of renal function (within hours or days), with clinical symptoms ranging from a minor rise in serum creatinine to anuric renal failure needing renal replacement therapy. AKI is one of the complications of acute coronary syndrome (ACS). This study aims to determine the frequency of AKI among patients with ACS and identify its predictors.

Transversus Abdominis Plane Block Versus Local Anesthetic Wound Infiltration for Postoperative Analgesia in Adult Patients Undergoing Hernia Repair in Daycare Procedure: A Randomized Control Trial.

Introduction: Various modalities are now being used to manage postoperative pain, such as regional nerve blocks techniques, continuous epidural analgesia, patient-controlled analgesia, opioids, and systemic non-steroidal anti-inflammatory drugs. This study compared the mean postoperative pain score between ultrasound-guided transversus abdominis plane (TAP) block and a local anesthetic wound infiltration at the surgical incision site.

Methodology: A prospective, comparative, randomized controlled trial (RCT) was carried out from February 2021 to September 2021.

The Impact of Charlson Comorbidity Index on Mortality From SARS-CoV-2 Virus Infection.

Introduction: Charlson Comorbidity Index (CCI) is a simple, validated, and readily acceptable method of determining the risk of mortality from comorbid disease. It has been used as a predictor of long-term survival and prognosis. The aim of this study is to determine the impact of CCI score on mortality in COVID-19 hospitalized patients and test the efficacy of the CoLACD score (COVID-19 lymphocyte ratio, age, CCI score, dyspnoea) in predicting mortality among hospitalized COVID-19 patients.
