Prevalence of anemia and its social determinants among the male residents of an urban area in Tamil Nadu, India.

Introduction: India has a high burden of anemia among the South Asian countries. Anemia has been extensively studied in the female and child population, with less attention given to males. The present study aims to assess the prevalence of anemia among males residing in an urban area and associated social determinants.

Experiences of hospitalized patients with COVID-19 - A single centre qualitative study.

Introduction: COVID-19 pandemic caused a huge impact on the healthcare system worldwide. With a spectrum of outcome ranging from mild symptoms to mortality, the experiences of patients admitted in isolation wards have not been documented.

Objective: To explore the experience of COVID-19 patients during hospitalization during the early phase of pandemic.

Exploration and Enhancement of Classifiers in the Detection of Lung Cancer from Histopathological Images.

Lung cancer is a prevalent malignancy that impacts individuals of all genders and is often diagnosed late due to delayed symptoms. To catch it early, researchers are developing algorithms to study lung cancer images. The primary objective of this work is to propose a novel approach for the detection of lung cancer using histopathological images.

Surveying the Indian research ethics committee response to the COVID-19 pandemic.

Research ethics committees (RECs) have played a crucial role in expediting the review of research protocols amidst the COVID-19 pandemic. To improve their performance and identify areas of enhancement, a multicentric study was conducted in India by the Forum for Ethical Review Committees in the Asian and Western Pacific Region (FERCAP). The study aimed to evaluate the preparedness of Indian RECs during the COVID-19 outbreak while conducting protocol reviews and comprehend the challenges they encountered.

Interventional Fairness with Indirect Knowledge of Unobserved Protected Attributes.

The deployment of machine learning (ML) systems in applications with societal impact has motivated the study of fairness for marginalized groups. Often, the protected attribute is absent from the training dataset for legal reasons. However, datasets still contain proxy attributes that capture protected information and can inject unfairness in the ML model.

Peer Educators as Change Leaders - Effectiveness of Peer Education Process in Creating Awareness on Reproductive Health among Women Workers in Textile Industry.

Context: India is one of the leading manufacturers of garments with roughly 80% of the workforce dominated by female migrant workers. Lack of education and access to resources in these women contribute to unsafe sexual behaviors, sometimes leading to unwanted pregnancies or sexually transmitted infections (STIs). Awareness raising, and peer education in particular, is extremely effective in addressing reproductive health issues.

Efficient Algorithms for Coded Multicasting in Heterogeneous Caching Networks.

Coded multicasting has been shown to be a promising approach to significantly improve the performance of content delivery networks with multiple caches downstream of a common multicast link. However, the schemes that have been shown to achieve order-optimal performance require content items to be partitioned into several packets that grows exponentially with the number of caches, leading to codes of exponential complexity that jeopardize their promising performance benefits. In this paper, we address this crucial performance-complexity tradeoff in a heterogeneous caching network setting, where edge caches with possibly different storage capacity collect multiple content requests that may follow distinct demand distributions.

Microvascular blood flow in normal and pathologic rotator cuffs.

Background: Microvascular blood flow in the tendon plays an important role in the pathogenesis of rotator cuff abnormalities. There are conflicting views about the presence of a hypovascular zone in the supraspinatus tendon. Besides, no studies have looked at the pattern of blood flow around a partial-thickness tear.

Ultrasound dimensions of the rotator cuff in young healthy adults.

Background: No studies have looked at the rotator cuff dimensions in the young healthy population using ultrasonography. Our aim is to define the ultrasound dimensions of the rotator cuff in the healthy young adult population and explore correlations with other patient characteristics.

Methods: Thirty male and 30 female healthy volunteers (aged 18-40 years), with no shoulder problems, underwent ultrasound assessment of both shoulders by a musculoskeletal radiologist.

Accuracy of abduction-external rotation MRA versus standard MRA in the diagnosis of intra-articular shoulder pathology.

The goal of this study was to compare the accuracy of abduction-external rotation magnetic resonance arthrography (ABERMRA) with standard MRA in the diagnosis of intra-articular shoulder pathology.One hundred three consecutive patients undergoing preoperative direct MRA and subsequent arthroscopic examination were included in the study. Seventy-eight patients underwent standard MRA and 25 underwent ABERMRA.

Microfracture for acetabular chondral defects in patients with femoroacetabular impingement: results at second-look arthroscopic surgery.

Background: Microfracture is a proven technique to treat articular cartilage defects in the knee. However, there is little evidence in the literature to confirm the ability of microfracture to produce repair tissue in the hip joint.

Purpose: The purpose of this study was to report the macroscopic and microscopic appearances of repair tissue after microfracture performed at hip arthroscopic surgery for isolated full-thickness acetabular cartilage defects in patients with femoroacetabular impingement (FAI).

The accuracy of automatic calibration of digital pelvic radiographs using two different scale markers: a comparative study.

We have investigated the accuracy of automatic calibration of digital pelvic radiographs using the single and double marker techniques. Both markers were applied by the radiographer at the time of routine, postoperative radiographs. Each radiograph was loaded into the TraumaCad(TM) software package which calculated the magnification and scaled the radiograph automatically.

The use of warfarin as thromboprophylaxis for lower limb arthroplasty.

Introduction: Most orthopaedic surgeons in the UK use some form of prophylaxis against venous thromboembolic events. Warfarin has been recommended as one of the preferred methods to use. The period of in-hospital postoperative rehabilitation has reduced significantly since lower limb arthroplasty was introduced.

Referral pattern and surgical outcome of sagittal synostosis.

Summary: Sagittal synostosis (SS) is the commonest form of craniosynostosis, and in the Birmingham Craniofacial Unit has been preferably managed by strip craniectomy when the baby is under 6 months of age or calvarial remodelling when over 6 months old. The unit uses cephalic index (CI) as an objective measure of head shape. This retrospective study analysed referral patterns and the correlation between age at operation and CI.
