Factors Impacting Quality of Life of Caregivers of Cancer Patients in the Sub-Himalayan Region: A Cross-Sectional Study.

Background Caregivers of cancer patients experience excessive emotional and financial stress. Objective To determine the quality of life (QOL) of caregivers of cancer patients and factors affecting it in caregivers attending the OPD of a governmental tertiary care cancer center in the sub-Himalayan region. Methods A cross-sectional observational study was used.

Immunohistochemical analysis and correlation of cyclooxygenase-2 expression status with clinicopathological parameters in head and neck squamous cell carcinomas: An Indian perspective.

Context: Head and neck squamous cell carcinoma (HNSCC) poses a major health problem and despite the advancements in its diagnosis and management the overall survival has not improved significantly. A search for newer diagnostic and prognostic markers along with fresh molecular targets is required for its prevention and cure.

Aims: The study aims to study the expression of cyclooxygenase-2 (COX-2) in HNSCCs and investigate its correlation with the clinicopathological profile of these cases.

Depression among Indian university students and its association with perceived university academic environment, living arrangements and personal issues.

The aim of the study is to ascertain the level of depression among university students across gender, academic stream, semesters, perception of family environment and relationship with parents, academic performance, and family income. In addition, the study examines the association between students' perceived university academic environment, living arrangements, personal issues, and depression. Seven hypotheses were formulated for verification.

Mixed Phenotypic Acute Leukemia Presenting as Mediastinal Mass-2 Cases.

Mixed phenotype acute leukemia symbolizes a very small subset of acute leukemia that simply cannot be allocated as lymphoid or myeloid lineage. The 2008 World Health Organisation classification established stringent standard for diagnosis of mixed phenotype acute leukemia, accentuating myeloperoxidase for myeloid lineage, cytoplasmic CD3 for T lineage and CD19 with other B markers for B lineage obligation. Mixed phenotype leukemia is rare and 3-5 % of acute leukmias of all age groups, is associated with poor outcome with overall survival of 18 months.

Binary classification using multivariate receiver operating characteristic curve for continuous data.

The classification scenario needs handling of more than one biomarker. The main objective of the work is to propose a multivariate receiver operating characteristic (MROC) model which linearly combines the markers to classify them into one of the two groups and also to determine an optimal cut point. Simulation studies are conducted for four sets of mean vectors and covariance matrices and a real dataset is also used to demonstrate the proposed model.

Angiotensin converting enzyme gene polymorphism in type II diabetics with nephropathy.

Nephropathy is an important and a frequent complication of long-term type II diabetic nephropathy. Strong evidence exists that genetic predisposition plays a major role in the development of diabetic nephropathy. Recent studies have implicated association between angiotensin converting enzyme (ACE) insertion/deletion (I/D) gene polymorphism and nephropathy.

Association of hyperparathyroidism with nonmedullary thyroid carcinoma: review of 31 cases.

In a series of 948 patients operated on for primary hyperparathyroidism (HPT) by one surgeon (JNA) from 1952 to 1992, there were 242 (26%) instances of coincidental thyroid and parathyroid disease. Of these, 211 had benign thyroid lesions. In the remaining 31 cases HPT was associated with nonmedullary thyroid carcinoma; all were treated by resection of parathyroid adenomas and thyroidectomy.
