Real questions from health communities, answered with cited research from PubMed and Vellito's article corpus. Plain language, no medical advice. How this works.
Yes, a specific saliva test measuring IgA antibodies to EBNA1 protein can accurately predict NPC risk, with sensitivity up to 90% and specificity over 91%.
Yes, saliva samples can help predict nasopharyngeal carcinoma (NPC) risk by detecting EBV markers and microbial changes, but they are not yet standard for other cancers.
Yes, aflibercept biosimilars are as safe and effective as the original drug for diabetic macular edema, based on a systematic review and meta-analysis.
Yes, giving a femoral nerve block before surgery reduces rebound pain more effectively than giving it after surgery, according to a 2024 trial.
Yes, insurance delays in Indonesia can impair early rehabilitation and functional recovery after total knee arthroplasty.
A 2024 study found that while a larger tibial slope (>10°) increases implant migration, it does not affect polyethylene wear or implant survival at 5 years.
For patients under 50, about 87% of knee implants still work after 10 years, according to a 2024 meta-analysis.
Yes, ThuLEP generally results in a shorter hospital stay than RASP for large BPH, though some studies show no difference.
After prostate resection for BPH, the risk of developing bladder stones is low but increases with certain factors like larger prostate volume, higher symptom scores, and elevated…
Yes, combining radiotherapy with anti-VEGF therapy increases the risk of vision loss compared to anti-VEGF alone, based on systematic reviews.
Prone positioning for COVID-19 ARDS improves oxygenation and may reduce mortality, especially with extended sessions (>24 h), but increases pressure injury risk.
Yes, Eylea HD (aflibercept) is FDA-approved to treat neovascular (wet) age-related macular degeneration (nAMD).
Yes, Pavblu (aflibercept) is FDA-approved specifically for neovascular AMD, so it can treat your condition.
Anti-VEGF injections for AMD block abnormal blood vessel growth but may also activate immune pathways, including T-cell and inflammatory signals, which could affect long-term…
Yes, aflibercept biosimilars are as safe and effective as the original drug for neovascular AMD, based on a meta-analysis of 11 studies.
Yes, prolonged prone positioning (≥24 hours) improves oxygenation in ARDS, but its effect on mortality is uncertain and it increases pressure injury risk.
Yes, lung ultrasound is a reliable, non-invasive tool for diagnosing ARDS, with high specificity (87%) and good sensitivity (75%) according to a large meta-analysis.
Research shows long COVID patients have distinct immune signatures compared to healthy people, including increased monocyte activation and signs of immune exhaustion.
Yes, Keytruda (pembrolizumab) is FDA-approved for treating unresectable or metastatic melanoma.
MicroRNAs are small RNA molecules that can promote or suppress melanoma growth, invasion, and spread by controlling gene activity and influencing the tumor's immune environment.
Yes, a meta-analysis of 10 studies found VR interventions significantly reduce stress and anxiety in healthcare workers, with moderate to large effect sizes.
Yes, anti-inflammatory diets like the Mediterranean diet may help reduce stress symptoms by lowering inflammation, though direct evidence is still emerging.
Yes, a 12-week breathwork protocol significantly reduced stress and anxiety in paramedic students in a randomized controlled trial.
A 2024 trial found that high-frequency music therapy reduced stress better than low-frequency sessions in adult psychiatric patients, but other research shows various other…
We pull real patient questions from public Reddit health communities (r/AskDocs, r/diabetes, r/menopause, etc.). Each question is rewritten into a generic medical question (no personal details), then answered by an AI using only cited sources from Vellito's article database and PubMed. A second AI independently scores each answer for accuracy and citation fidelity before publication. Answers below the safety threshold or touching emergency, dosing, or pediatric topics are queued for human review and never auto-published.
