Insights

Subclinical vitamin A deficiency affects 35.7% of children under six in Nagpur

Area of Science:

  • Nutritional epidemiology
  • Public health
  • Ophthalmology

Background:

  • Subclinical vitamin A deficiency poses a significant public health risk in developing nations.
  • Early detection and intervention are crucial to prevent irreversible health consequences like xerophthalmia.

Purpose of the Study:

  • To estimate the prevalence of subclinical vitamin A deficiency in urban slum children under six years old in Nagpur, India.
  • To identify potential risk factors associated with this deficiency.

Main Methods:

  • A cross-sectional study involving 308 non-xerophthalmic children under six.
  • Conjunctival impression cytology was used as the diagnostic method.
  • Random sampling was employed in urban slums of Nagpur.

Main Results:

  • A high prevalence of 35.7% for subclinical vitamin A deficiency was found.
  • The deficiency showed a non-significant association with increasing age.
  • Severely malnourished children exhibited a higher prevalence of the deficiency.

Conclusions:

  • The observed prevalence significantly exceeds WHO criteria, necessitating community-wide interventions.
  • Undiagnosed subclinical vitamin A deficiency in apparently healthy children can lead to severe outcomes if infections occur.
  • Timely vitamin A supplementation is critical to mitigate the risk of xerophthalmia and its complications.

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

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 in our...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Type I Diabetes III: Clinical Manifestations

Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
