Evaluation of Characteristics and Outcomes of COVID-19 Between First Wave and Second Wave: Study From a Tertiary Cancer Care Centre, Delhi, India.

Background and objectives The second wave of coronavirus disease-19 (COVID-19) had several severe consequences in the form of rising cases, deaths, and overwhelming health infrastructure in India. However, the similarities and differences between the characteristics of the first and second waves have yet to be explained. The objectives of the study were to compare the incidence, clinical management, and mortality rates between two waves.

Cross-Sectional Study to Establish the Utility of Serum Tumor Markers in the Diagnosis of Lung Cancer.

Background: Reliable blood markers for aiding lung cancer (LC) diagnosis and differentiating LC from tuberculosis are lacking in India.

Methodology: In this single-centre, cross-sectional, real-world study, serum levels of 5 TMs (CEA, CYFRA 21-1, SCC, ProGRP, NSE) were measured from consented patients with suspicious lung nodules who were candidates for biopsy, and also from healthy controls. TM level measurement was done through electrochemiluminescent immunoassay, followed by histological diagnosis on the biopsied specimen.

COVID-19 mortality in cancer patients: a report from a tertiary cancer centre in India.

Background: Cancer patients, especially those receiving cytotoxic therapy, are assumed to have a higher probability of death from COVID-19. We have conducted this study to identify the Case Fatality Rate (CFR) in cancer patients with COVID-19 and have explored the relationship of various clinical factors to mortality in our patient cohort.

Methods: All confirmed cancer cases presented to the hospital from June 8 to August 20, 2020, and developed symptoms/radiological features suspicious of COVID-19 were tested by Real-time polymerase chain reaction assay and/or cartridge-based nucleic acid amplification test from a combination of naso-oropharyngeal swab for SARS-CoV-2.

Bisalbuminemia: A Rare Finding on Serum Electrophoresis.

Bisalbuminemia is an uncommon finding that is seen as bifid albumin peak on serum protein electrophoresis. We report here this unusual finding in an adult male diagnosed with multiple myeloma on routine workup.

Preanalytical error occurrence rate in clinical chemistry laboratory of a public hospital in India.

Background: The pre and post analytical phase in a testing cycle contributes up to 93% of total laboratory errors. Hence, it is of utter importance for the laboratory to study error occurrence rates during the testing cycle and implement a quality improvement plan to release an accurate result.

Methods: The present study was conducted during the period 2008 - 2009 in the clinical biochemistry lab in Lady Hardinge Medical College and associated hospitals.

Metabolic effects of obesity: A review.

With the many recent advances in the biomedical world, vast changes are taking place in our growing knowledge of the physiological aspects of almost all the tissues and organs of the human body. One of the most prevalent topics of discussion is the question of obesity and its effect on the metabolic changes in the human body. The original classical role of adipose tissue as an energy storage organ has been greatly modified.
