Arsenic efflux and bioremediation potential of Klebsiella oxytoca via the arsB gene.

Arsenic-resistant Klebsiella oxytoca strain AT-02 was isolated from the ground water of the Multan region of Pakistan. The strain displayed high arsenite and arsenate resistance as minimal inhibitory concentration (MIC) was 600ppm and 10,000ppm respectively. The high tolerance of the isolated strain towards arsenate can be postulated due to significant increase in biofilm in response to arsenate.

The Role of Fluoroscopic Guidance in Spinal Drain Placement for Thoracoabdominal Aneurysm Repair Patients: A Retrospective Study.

Objectives: To evaluate outcomes after implementation of a preoperative protocol requiring fluoroscopic guidance in patients undergoing thoracoabdominal aortic aneurysm (TAAA) repair identified as being at risk for spinal drain placement complications.

Design: This retrospective analysis included patients who underwent spinal drain placement for TAAA repair between November 2013 and November 2018. Patient outcomes were assessed before (control) and after (study) protocol implementation.

Ramadan intermittent fasting for patients with gastrointestinal and hepatobiliary diseases: practical guidance for health-care professionals.

Ramadan intermittent fasting can pose challenges and risks for some groups of patients. Based on a narrative literature review and our clinical expertise, we provide practical guidance for clinicians managing patients with gastrointestinal and hepatobiliary conditions who wish to fast during Ramadan. Following the established International Diabetes Federation and Diabetes and Ramadan International Alliance risk stratification framework, we categorised patients' risk as low or moderate, high, or very high.

Comparison of Research Knowledge in Postgraduate Trainees of Clinical and Basic Health Sciences of a Tertiary Healthcare Setup: A Qualitative and Quantitative Assessment.

Background:  All recent advances in healthcare, including diagnostics, surveillance, management, and disease prevention, have depended on good-quality research that has brought new information to light. Therefore, in Pakistan, it is important to develop good research skills as, for many years, our physicians have relied on research knowledge from the Western world, which does not necessarily provide solutions to a developing country. Considering the gap in research knowledge among young doctors, the study was planned to compare the research knowledge of postgrad trainees of clinical and basic health sciences (BHS) of private tertiary care hospitals in Karachi.

Amivantamab Plus Lazertinib in Patients With EGFR-mutant Non-small Cell Lung Cancer (NSCLC) After Progression on Osimertinib and Platinum-based Chemotherapy: Results From CHRYSALIS-2 Cohort A.

Introduction: Treatment options for patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) with disease progression on/after osimertinib and platinum-based chemotherapy are limited.

Methods: CHRYSALIS-2 Cohort A evaluated amivantamab+lazertinib in patients with EGFR exon 19 deletion- or L858R-mutated NSCLC with disease progression on/after osimertinib and platinum-based chemotherapy. Primary endpoint was investigator-assessed objective response rate (ORR).
