Prognostic Nutritional Index (PNI) and Systemic Immune-Inflammatory Index (SII) as markers of severity among patients having COVID-19 infection.

Background: Prognostic nutritional index (PNI) and systemic immune-inflammatory index (SII) are two novel markers that have emerged as potential candidates as an early indication of the severity of the disease in coronavirus disease 2019 (COVID-19) patients.

Objective: The objective of the study is to assess the utility of the prognostic nutritional index (PNI) and systemic immune-inflammatory index (SII) as markers of severity among patients with COVID-19 infection.

Methods: This is a retrospective study conducted in a tertiary care centre in South India.

Study of Serum Gamma-Glutamyl Transferase Levels in Patients With Acute Ischemic Stroke.

Background Gamma-glutamyl transferase (GGT) mediates intracellular uptake of glutathione which is a known antioxidant. GGT levels are found to be elevated in conditions of oxidative stress. Ischemic stroke results in anoxic injury, which liberates free radicals, causing glutathione to rise, which may be accompanied by a rise in serum GGT levels.

Serum Cystatin C Levels as a Predictor of Severity and Mortality Among Patients With COVID-19 Infection.

Introduction: The pandemic caused by SARS Corona Virus-2 (COVID-19) has caused widespread mortality globally. The hallmark of the disease is the "cytokine storm," which is caused due to dysregulated immune system activation. Numerous inflammatory markers are used to predict the severity and mortality of the infection.

Assessment of Functions of the Autonomic Nervous System in the Elderly with Different Comorbid Factors.

 Studies in healthy elderly patients have shown the prevalence of autonomic dysfunction (AD) in the range of 20 to 30%. However, there is paucity in data pertaining to AD in the elderly in the Indian context.  To assess the prevalence of AD in the elderly irrespective of their comorbidity status.

Clinical Profiles of Elderly Patients Presenting with Persistent Dizziness.

Background: Dizziness among elderly patients is primarily treated in emergency and primary care centers. However, the causes and comorbidities responsible for dizziness in the elderly may differ in tertiary health care centers.

Objective: To determine the subtypes of persistent dizziness and to evaluate the number of contributory causes of dizziness among elderly patients.

Hypokalaemic Periodic Paralysis in a Patient with Subclinical Hyperthyroidism: A Rare Case.

Thyrotoxic Periodic Paralysis (TPP) is an uncommon disorder. Though many cases of hypokalaemic periodic paralysis are reported in overt hyperthyroidism, hypokalaemic paralysis in subclinical hyperthyroidism is very rare. Subclinical hyperthyroidism is characterised by circulating TSH levels below reference range and normal thyroid hormone levels.
