Pre-surgery Stress Monitoring Using Heart Rate Variability Measures.

Pre-surgery stress is common in patients hospitalized for undergoing surgeries. High levels of stress could prolong post-operative recovery time, increasing the duration of hospitalization. Abnormally high stress levels could sometimes have irreversible impacts, leading to post-operative physiological and psychological disorders.

Completion Rates and Clinical Changes of Patients Seeking Non-Invasive Treatment for Low Back Pain in 13 Centres of a Sports Medicine Institute in India.

Background/aim: Low back pain (LBP) is the major cause of disability worldwide. The existing treatments are expensive and associated with complications. The present study aimed to determine the proportion of patients completing therapy and rehabilitation phases and describe the changes in self-reported symptoms and functional disability among LBP patients enrolled in a private sports medicine institute.

Objective quantification of corneal haziness using anterior segment optical coherence tomography.

Purpose: To quantify normal corneal transparency by anterior segment optical coherence tomography (AS-OCT) by measuring the average pixel intensity. To analyze the variation in the average pixel intensity in mild and severe grades of corneal opacities.

Methods: This is an observational, cross-sectional study of 38 eyes from 19 patients with mild or severe grades of corneal opacities greater than 3 mm and a normal contralateral cornea.

Extended localization and adaptive dose calculation using HU corrected cone beam CT: Phantom study.

Background And Aim: The practicability of computing dose calculation on cone beam CT (CBCT) has been widely investigated. In most clinical scenarios, the craniocaudal scanning length of CBCT is found to be inadequate for localization. This study aims to explore extended tomographic localization and adaptive dose calculation strategies using Hounsfield unit (HU) corrected CBCT image sets.
