How does the quality of life and the underlying biochemical indicators correlate with the performance in academic examinations in a group of medical students of Sri Lanka?

Background: Individual variation of examination performance depends on many modifiable and non-modifiable factors, including pre-examination anxiety. Medical students' quality of life (QoL) and certain biochemical changes occurring while they are preparing for examinations has not been explored.

Purpose: We hypothesize that these parameters would determine the examination performance among medical students.

Effects of zinc and multimineral vitamin supplementation on glycemic and lipid control in adult diabetes.

Aims: To evaluate the effects of zinc with or without other antioxidants on blood glucose, lipid profile, and serum creatinine in adult diabetics on long-term follow-up.

Materials And Methods: Patients (n = 96) were randomly allocated to three groups: group A (n = 29) was supplemented with oral zinc sulfate (22 mg/day) and multivitamin/mineral (zinc+MVM) preparation; group B (n = 31) was given the same preparation without zinc (MVM); and group C (n = 36) was given a matching placebo for a period of 4 months in a single-blinded study. Blood samples were taken at baseline and after 4 months of supplementation to assess blood glucose (fasting and postprandial) and glycosylated hemoglobin (Hb(A1C)%) and serum levels of zinc, creatinine, and lipids.
