Insights

Vitamin-A (Vit-A) prophylaxis in India showed decreased deficiency signs but mass programs had low coverage and potential harm. A food-based approach with targeted Vit-A supplementation is recommended over "one size fits all" strategies.

Area of Science:

  • Public Health Nutrition
  • Ophthalmology
  • Pediatrics

Background:

  • Childhood blindness from corneal ulceration was a significant issue in India.
  • A national Vitamin-A (Vit-A) prophylaxis program was initiated in 1970 by the National Institute of Nutrition (NIN).
  • While Vit-A deficiency signs decreased, attributing this solely to mass prophylaxis is uncertain due to low and patchy coverage.

Purpose of the Study:

  • To evaluate the effectiveness and potential harms of mass Vitamin-A prophylaxis in Indian children.
  • To explore alternative and complementary strategies for addressing Vitamin-A deficiency.
  • To advocate for a more targeted and resource-efficient approach to Vitamin-A supplementation.

Main Methods:

  • Review of documented data on Vitamin-A deficiency prevalence and prophylaxis program coverage.
  • Analysis of factors contributing to improved nutritional status and reduced deficiency signs.
  • Examination of research findings on the adverse effects of high-dose Vitamin-A supplementation.

Main Results:

  • Mass Vitamin-A prophylaxis coverage was low and inconsistent.
  • Improved nutrition, vaccination, breastfeeding, and healthcare services likely contributed to reduced deficiency.
  • High-dose Vit-A supplementation carries risks of acute toxicity and impaired growth in susceptible children.

Conclusions:

  • A "one size fits all" mass Vitamin-A prophylaxis approach may be harmful and inefficient.
  • A food-based approach, including breastfeeding and Vit-A rich foods, is crucial.
  • Targeted supplementation for children with deficiency signs or post-measles is recommended, alongside timely measles vaccination.

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Phase Diagrams

A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...

Personality Disorders: Narcissistic and Avoidant

Narcissistic and avoidant personality traits represent two contrasting patterns of behavior that significantly influence social interactions and self-perception. While individuals with narcissistic disorder seek admiration and validation, individuals with avoidant personality disorder withdraw due to fear of judgment.
Characteristics of Narcissistic Personality Disorder
Narcissistic individuals exhibit an inflated sense of self-importance and an excessive need for admiration. They are often...
