Medical examination of divers after COVID-19 infection: a prospective, observational study using published (original and revised) guidelines for evaluation.

Introduction: The COVID-19 pandemic raised significant concerns about fitness to dive due to potential damage to the pulmonary and cardiovascular systems. Our group previously published guidelines (original and revised) for assessment of these divers. Here, we report a prospective, observational study to evaluate the utility of these guidelines.

Longitudinal changes in bone mineral density may be associated with long-term survival in patients with cirrhosis: A proof of concept of study.

Introduction: The impact of longitudinal changes in different body components measured via body composition analysis (BCA) on liver-related outcomes in patients with cirrhosis is poorly understood. We evaluated the prognostic relevance of longitudinal changes in body composition over one year in patients with cirrhosis.

Methods: This was a follow-up study of a randomized controlled trial evaluating changes in bone density measured via dual energy X-ray absorptiometry (DEXA) upon vitamin D supplementation.

Comparative Evaluation of Fracture Toughness and Flexural Strength of Four Different Core Build-up Materials: An Study.

Aim: To evaluate and compare the fracture toughness and flexural strength of four different core build-up materials.

Materials And Methods: A total of 60 samples were divided into four groups ( = 15) group I: dual cure composite resin reinforced with zirconia particles (Luxacore Z), group II: light cure composite resin (Lumiglass DeepCure), group III: zirconia reinforced glass ionomer cement (GIC) (Zirconomer Improved), and group IV: chemically cure composite resin (Self Comp) respectively. All the core build-up materials were manipulated according to the manufacturer's instructions and poured into the mold.

Kitchen-based diet versus commercial polymeric formulation in acute pancreatitis: a pilot randomized comparative study.

Introduction: Nutrition plays an important role in management of acute pancreatitis (AP) and decreases its severity and infectious complications. Various formulations of enteral nutrition (EN) are available and are costly. For developing countries, cost and availability is a major issue and kitchen-based diet should be explored in patients with AP.

Vitamin D status & bone health in patients with liver cirrhosis.

Background & Objectives: Vitamin D plays an important role in bone metabolism, and liver is the intermediary site of vitamin D metabolism. The purpose of this study was to study the prevalence of vitamin D deficiency and bone health in patients with cirrhosis.

Methods: Prospectively, serum 25-hydroxy vitamin D [25(OH)D] level were assessed in cirrhotics by chemiluminescence method.
