Prediction of low birth weight from fetal ultrasound and clinical characteristics: a comparative study between a low- and middle-income and a high-income country.

Introduction: Adverse perinatal outcomes (APO) pose a significant global challenge, particularly in low- and middle-income countries (LMICs). This study aims to analyse two cohorts of high-risk pregnant women for APO to comprehend risk factors and improve prediction accuracy.

Methods: We considered an LMIC and a high-income country (HIC) population to derive XGBoost classifiers to predict low birth weight (LBW) from a comprehensive set of maternal and fetal characteristics including socio-demographic, past and current pregnancy information, fetal biometry and fetoplacental Doppler measurements.

Disinfection of Impression Materials with Glutaraldehyde, Ultraviolet Radiation, and Autoclave: A Comparative Study.

Background: The present study was conducted to compare various methods of disinfection of impression materials such as glutaraldehyde, ultraviolet (UV) radiation, and autoclave.

Materials And Methods: The present study was conducted on eighty alginate impression materials which were disinfectant with 2.2% glutaraldehyde, UV radiation, and autoclave.

A Comparative Evaluation of Marginal Accuracy of Co-Cr Metal Copings Fabricated Using Traditional Casting Techniques and Metal Laser Sintering.

Aims And Objectives: The aim and objective of the study were to determine the amount of marginal discrepancy produced by cobalt-chromium (Co-Cr) copings fabricated using two different fabrication methods, i.e., traditional casting and direct metal laser-sintering (DMLS), and compare the values obtained between each fabrication technique and to evaluate if the fabrication technique can produce prosthesis that is within the standards of clinical acceptance of marginal discrepancy.

Comparison of clinical characteristics and outcomes between COVID-19 pneumonia and H1N1 influenza.

Introduction: The COVID-19 pandemic has been likened to the 2009 H1N1 influenza pandemic. We aim to study the similarities and differences between patients hospitalized with COVID-19 and H1N1 influenza in order to provide better care to patients, particularly during the co-circulation of Influenza A Subtype H1N1 and SARS-CoV-2.

Material And Methods: A retrospective cohort study was conducted in order to compare clinical characteristics, complications, and outcomes of hospitalized patients with PCR-confirmed H1N1 influenza pneumonia and COVID-19 at a tertiary care center in Karachi, Pakistan.

A Comparative Study to Evaluate the Accuracy of Various Spacer Thickness for Polyvinyl Siloxane Putty-wash Impression Techniques: An Study.

Introduction: An accurate impression is one of the prime factors for success of any restoration, more so in field of fixed prosthodontics. The critical aspect is to reproduce fine surface details along with ease of use. Knowledge of impression materials and the techniques to which each is best suited is essential in achieving consistent results.

Adult congenital heart disease: frequency, risk factors and outcomes of acute kidney injury in postoperative period.

Background: Acute kidney injury (AKI) after surgery for congenital heart disease (CHD) in adults is poorly studied despite being well-recognized as a postoperative complication after cardiac surgery in adults. The primary aim of our study was to determine the frequency of AKI in adults undergoing surgery for CHD. We also aimed to determine risk factors and predictors of AKI in this patient population, and to explore outcomes in terms of duration of mechanical ventilation, intensive care unit (ICU) stay, and hospital stay.

Granulomatosis with polyangiitis: a 17 year experience from a tertiary care hospital in Pakistan.

Objective: Granulomatosis with Polyangiitis (GPA) is an autoimmune, multi-system, small and medium vessel vasculitis with granulomatous inflammation. Aim of this study was to assess the clinical and radiological presentations of patients with GPA amongst the Pakistani population. It is a single centre retrospective single observation study.

Just a mirage: heterotopic intrauterine and twin ectopic pregnancy mimicked by mirror imaging on ultrasound.

Heterotopic pregnancies are rare and are usually diagnosed by transvaginal ultrasound. Despite the routine use of sonography in early pregnancy, artifact created by mirror imaging can drastically and erroneously alter medical decision making by interfering with image interpretation. A heterotopic pregnancy with a single intrauterine gestation and twin left adnexal ectopic gestational sacs was observed on ultrasound in a woman presenting with abdominal pain.

Hospitalizations for students with an alcohol-related sanction: gender and pregaming as risk factors.

Objective: The purpose of this study is to investigate whether pregaming (ie, drinking prior to a social event) is a risk factor for hospitalization.

Participants: Participants (N = 516) were undergraduate students with an alcohol-related sanction.

Methods: Participants completed a survey about alcohol use, as well as behaviors and experiences, prior to and during the referral event.
