Adsorptive membrane separation for eco-friendly decontamination of chlorpyrifos via biochar-impregnated cellulose acetate mixed matrix membrane.

In this work, the phase inversion approach is used to synthesize a blended mixed matrix membrane from cellulose acetate polymer and sugarcane bagasse biochar. The experiments were carried out to estimate the extent of chlorpyrifos (CPS) pesticide removal. The results showed that the removal rate was more than 99% in making the filtered water suitable enough for domestic use.

Assessing the utility of Truenat in extrapulmonary tuberculosis diagnosis - A NRL's experience.

Background: Diagnosis of extra pulmonary TB (EPTB) remains a big challenge. While data on utility of Xpert testing in EPTB diagnosis is enormous, there is limited data on Truenat MTB testing.

Aim: In this study we aimed to evaluate the usefulness of Truenat in EPTB diagnosis.

Strategies for safe management of hospital wastewater during the COVID-19 pandemic.

Unlabelled: Management of hospital wastewater is a challenging task, particularly during the situations like coronavirus 2019 (COVID-19) pandemic. The hospital effluent streams are likely to contain many known and unknown contaminants including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) along with a variety of pollutants arising from pharmaceuticals, life-style chemicals, drugs, radioactive species, and human excreta from the patients. The effluents are a mixed bag of contaminants with some of them capable of infecting through contact.

Safety and feasibility of freehand transperineal prostate biopsy under local anesthesia: Our initial experience.

Introduction: With the emergence of multidrug-resistant organisms causing urosepsis after transrectal biopsy of prostate, the need for an alternative approach has increased. We assessed the safety and feasibility of transrectal ultrasound (TRUS) guided free-hand transperineal prostate biopsy under local anesthesia (LA) for suspected prostate cancer.

Materials And Methods: This prospective study was conducted from July 2019 to December 2020 in which patients with elevated prostate-specific antigen (PSA) and/or abnormal digital rectal examination underwent magnetic resonance imaging-TRUS cognitive fusion transperineal prostate biopsy (target and systematic) using coaxial needle.

Aorto-oesophageal fistula: rarest cause of haematemesis - is it salvageable?

A 60-year-old man presented with severe abdominal pain, two episodes of massive haematemesis and chest discomfort. CT angiography showed a saccular aneurysm of the juxtaphrenic aorta with possible oesophageal erosion. Upper GI endoscopy revealed external compression of the lower oesophagus-near total luminal obstruction with impending rupture of the aortic aneurysm.
