Can There be a Biometric Parameter for Voice?-An Investigation Into the Vocal Cry of Twins.

Unlabelled: The voice of an individual is the result of interaction between the laryngeal and supra-laryngeal structures of a person. Since the laryngeal and supra-laryngeal structures differ from one person to another, the voice produced by each person becomes unique and recognizably different from another person. If this uniqueness in voice can be found in the acoustic parameters of the voice, it can contribute to the fields of forensic speaker identification and voice biometrics.

Addressing the mental health needs of India's aging population: Understanding depression prevalence and social risk factors in tertiary care outpatients.

Cerebral venous sinus thrombosis: changing trends in the incidence, age and gender (findings from the CMC Vellore CVT registry).

Background: Multiple cerebral venous sinus thrombosis (CVT) registries from various geographical regions indicate that female gender, the use of contraceptive pills, pregnancy and puerperium are important risk factors. In this study, we report the changes in the epidemiology of patients with CVT managed over the past 26 years.

Methods: The CMC Vellore CVT registry is a prospectively maintained database at the Christian Medical College, Vellore since January 1995.

Echocardiography protocol and cardiometabolic phenotyping in Indian birth cohorts-the IndEcho study.

Background: Asian Indians are at higher risk of cardiometabolic disease compared to other ethnic groups, and the age of onset is typically younger. Cardiac structure and function are poorly characterized in this ethnic group. In this study, we describe image-acquisition methods and the reproducibility of measurements and detailed echocardiography characteristics in two large Indian population-based cohorts (the New Delhi and Vellore Birth Cohorts) from India.

Comparison of Point-of-Care PT-INR by Hand-Held Device with Conventional PT-INR Testing in Anti-phospholipid Antibody Syndrome Patients on Oral Anticoagulation.

Evidence on agreement of point-of-care (POC) INR testing with laboratory testing in APS patients on oral anticoagulation (OAC), is scarce. This study assessed agreement of paired PT INR testing by a POC device vs. conventional platform-based laboratory test, in APS patients on OAC using a pre-determined definition of agreement.

Role of Neutrophil Gelatinase-associated Lipocalin (NGAL) and Other Clinical Parameters as Predictors of Bacterial Sepsis in Patients Presenting to the Emergency Department with Fever.

Background: Bacterial sepsis is associated with significant morbidity and mortality. However, to date, there is no single test that predicts sepsis with reproducible results. We proposed that using a combination of clinical and laboratory parameters and a novel biomarker, plasma neutrophil gelatinase-associated lipocalin (NGAL) may aid in early diagnosis.

Bone health in ambulatory male patients with chronic obstructive airway disease - A case control study from India.

Objective: Chronic obstructive airway disease (COPD) is characterized by airflow limitation due to airway and/or alveolar abnormalities with significant extra-pulmonary manifestations. Bone health impairment is an extra-pulmonary complication of COPD which is less well studied in India. Moreover, it can contribute to significant morbidity and mortality.

To assess the utility of Narrow Band Imaging (NBI) as a diagnostic tool in evaluating laryngeal pathology in patients presenting with hoarseness. Study design: Prospective cross sectional diagnostic study. Methods: 200 patients with voice change were recruited and laryngeal findings documented with high definition flexible endoscopy with both white light and narrow band light and the representative still images recorded for analysis.

A cross sectional, observational study to evaluate the surgeons' knowledge and perspective on preoperative fasting guidelines in a tertiary care teaching hospital in Southern India.

Background And Aims: The preoperative fasting orders given by the Anesthesiologists as per ASA and Enhanced Recovery After Surgery protocol, are often modified by the surgeons, for practical convenience, which can end up with patients being starved for prolonged periods of time. Hence, this study was conducted among various specialty surgical colleagues, to evaluate the knowledge and their perspective regarding patients' preoperative fasting guidelines.

Material And Methods: A validated questionnaire was distributed to 68 surgeons belonging to various surgical specialties, which included consultants and postgraduate residents.

High Counts in Hematologic Malignancies Predict Low Metaphase Yield for Cytogenetic Analysis.

Objectives: This study examined the impact of various preanalytical variables on metaphase yield in hematologic malignancies.

Methods: Marrow samples from patients with hematologic malignancies that were subjected to cytogenetic analysis were categorized into two groups: one with samples that yielded an adequate number of metaphases, defined as at least 20, and a second with a low number of metaphases (LNM), having fewer than 20 metaphases. Age, sex, bone marrow nucleated cell (MNC) count, and peripheral blood counts (hemoglobin, total WBC count, and platelet count) were analyzed for an association with LNM.

Impact of Grade on Survival in Pleomorphic Xanthoastrocytoma and Low Prevalence of BRAF V600E Mutation.

Background: The prevalence of BRAFV600E mutations in pleomorphic xanthoastrocytoma (PXA) World Health Organization (WHO) Grade 2 and PXA WHO Grade 3 reported varies from 60% to 80%, yet the prognostic implications remain unclear.

Methods: We reviewed the demographic and clinicoradiologic data of 20 PXAs WHO Grade 2 and 13 PXAs WHO Grade 3, operated between 2007 and 2020, to ascertain extent of excision, recurrence, progression-free survival (PFS), and overall survival (OS). PXAs WHO Grade 3 were defined by the presence of >5 mitoses/high-power field.

Role of hyperhomocysteinemia and Vitamin B12 deficiency in central and hemi-central retinal vein occlusion: A case-control study.

Background: Retinal venous occlusive diseases have been recognized as a major cause of ocular morbidity. Hyperhomocysteinemia could be a potentially modifiable risk factor.

Objective: To determine the association of hyperhomocysteinemia with central and hemi-central retinal vein occlusion (CRVO and HCRVO), the correlation of serum levels of homocysteine with Vitamin B12 and folate levels and the association of Vitamin B12 deficiency with hyperhomocysteinemia.

Stability and utility of flow cytometric platelet activation tests: A modality to bridge the gap between diagnostic demand and supply.

Light transmission aggregometry (LTA) is the gold standard for the diagnosis of platelet function disorders (PFDs). The requirement of customized aggregometer, large blood volume, normal platelet count and processing within 4 hours of venipuncture for LTA makes platelet function testing inaccessible to wider population. Flow cytometric platelet activation test (PACT) may overcome these limitations.

Impact of thyroidectomy on quality of life in benign goitres: results from a prospective cohort study.

Purpose: Benign thyroid diseases encompass a large spectrum of conditions that are chronic and subtle in nature. A majority of patients choose non-surgical management and continue living their daily lives with subconscious impairment of optimal functioning. We studied the effect of thyroidectomy on the quality of life (QoL) in patients with benign goitres.

Association between SpO/FiO Ratio and PaO/FiO Ratio in Different Modes of Oxygen Supplementation.

Background: Acute hypoxemic respiratory failure (AHRF) is a major factor for increased mortality in the intensive care unit (ICU). We hypothesized that the noninvasive index SpO/FiO (SF) ratio can be used as a surrogate to invasive index PaO/FiO (PF) as SF ratio correlates with PF ratio in all modes of oxygen supplementation.

Patients And Methods: Patients with acute respiratory failure admitted to the intensive care unit were enrolled in this retrospective cross-sectional study.
