Summary of Our Collaborative Research & Publications
1. Original Research: Propensity Score-Matched Cohort Study (Database Analysis)
Title: Differential Effects of GLP-1 Receptor Agonist and SGLT2 Inhibitor Add-on
Therapy on Outcomes Following Cardiac Surgery: A Propensity Score-Matched
Analysis
Journal: Cardiology in Review
Authors: Shankar Biswas, Ahmed Wahba, Yashasvi Srivastava, Karan Kumar,
Venkateswarlu Chintagumpala, Sameh M. Said
Status: Published Ahead of Print (July 23, 2026)
DOI: 10.1097/CRD.0000000000001393
My Contributions/Skills Demonstrated: Navigated the TriNetX US Collaborative
Network to perform complex data extraction on a massive patient cohort. I applied
rigorous propensity score matching to successfully balance baseline comorbidities and
glycemic control across groups, ultimately demonstrating the differential mortality
benefits of GLP-1 RAs versus SGLT2 inhibitors following cardiac surgery.
2. Methodological Critique & Evidence Synthesis (Infectious Disease)
Title: Power, dose, and fosfomycin in the SCOUT trial
Journal: The Lancet
Authors: Shankar Biswas, Yashasvi Srivastava, Victor Abiola Adepoju,
Venkateswarlu Chintagumpala, Abdulrakib Abdulrahim
Status: Published (August 8, 2026)
DOI: 10.1016/S0140-6736(26)01207-9
My Contributions/Skills Demonstrated: Critically appraised a major clinical trial
regarding single-dose fosfomycin for uncomplicated cystitis. I identified that the trial
was underpowered for its primary outcome and argued that the data supported a dose-
response dynamic rather than a drug class failure, highlighting the importance of
evaluating local resistance environments.
3. Advanced Statistical Critique (Cardiology/Geriatrics)
Title: Letter regarding the article ‘Modification of the association between age and
mortality in heart failure by frailty status’
Journal: European Journal of Heart Failure
Authors: Shankar Biswas, Yashasvi Srivastava, Venkateswarlu Chintagumpala
Status: Published (May 15, 2026)
DOI: 10.1093/ejhf/xuag164
My Contributions/Skills Demonstrated: Identified a critical methodological flaw in
a nationwide study's statistical analysis. I argued that by failing to account for non-
cardiovascular death as a competing risk, the absolute risk of cardiovascular mortality
was systematically overestimated in older, frail patients, and I advocated for cause-
specific survival analyses.
4. Clinical Pharmacotherapy Commentary (Cardiology)
Title: Letter by Biswas et al Regarding Article, 'Risk of Heart Failure Hospitalization
for GLP-1 Receptor Agonists Versus DPP-4 Inhibitors or SGLT-2 Inhibitors...'
Journal: Circulation
Authors: Shankar Biswas, Yashasvi Srivastava, Venkateswarlu Chintagumpala
Status: Accepted for publication
Manuscript ID: CIRCULATIONAHA/2026/081257
My Contributions/Skills Demonstrated: Synthesized clinical data to provide critical
commentary on heart failure hospitalization risks comparing multiple drug classes
(GLP-1 RAs, DPP-4is, SGLT-2is), expanding on our prior collaborative work in
evaluating cardiovascular pharmacotherapy outcomes.
