Research &
Development

Vedanadhi actively engages in research across a broad spectrum of health sciences, including:

  • Medicine and Surgery, encompassing both general practice and all super- and subspecialities.
  • Allied Health Sciences such as Nursing, Paramedical fields, Pharmacy, Physiotherapy, and Laboratory Sciences.
  • Public Health, Epidemiology, and related disciplines.

Our multidisciplinary research efforts focus on evidence synthesis, clinical outcomes, and health systems to address complex healthcare challenges. We welcome collaborations across diverse specialities and professions to advance knowledge and improve patient care.

"Childhood adversity and 5-HTTLPR across mental health outcomes: A transdiagnostic meta-analysis" — Vishnu Shivam

Background: Childhood maltreatment is associated with increased risk for various psychiatric disorders, although individual responses to early adversity vary. The serotonin transporter-linked polymorphic region (5-HTTLPR) has been examined as a potential moderator of sensitivity to environmental stress, but findings across studies have been inconsistent.

Objective: This meta-analysis examined whether 5-HTTLPR polymorphisms moderate the association between childhood adversity and clinically diagnosed psychiatric disorders.

Participants and settings: Fourteen studies (N = 3479) were included, representing community, population-based, and clinical samples from multiple regions.

Methods: Systematic searches of eight databases, last updated 3 December 2025, identified studies reporting 5-HTTLPR genotype, childhood adversity, and psychiatric diagnoses.

Results: Pooled analyses indicated no statistically significant interaction between childhood adversity and 5-HTTLPR genotype (ROR = 1.11, 95% CI 0.89-1.37).

Conclusion: Across available studies, evidence for an interaction between childhood adversity and 5-HTTLPR genotype was limited.

"Taste genomics and type 2 diabetes mellitus: a systematic qualitative meta-synthesis" — Vishnu Shivam, Sahana Kannan and Vishnu Harish

The current evidence suggests that genetic variations in taste receptor genes may contribute to T2DM through behavioral and metabolic mechanisms.
