Real questions from health communities, answered with cited research from PubMed and Vellito's article corpus. Plain language, no medical advice. How this works.
No, intravenous vitamin C did not reduce stomach problems during chemotherapy for nasopharyngeal carcinoma in a clinical trial.
Yes, taking aflibercept every 8 weeks maintains vision gains in diabetic macular edema, as shown in a 96-week trial where the 2 mg every 8 weeks regimen kept visual improvements…
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, helical tomotherapy (a form of IMRT) significantly reduces dry mouth (xerostomia) in nasopharyngeal carcinoma patients by sparing salivary glands, with low rates of severe…
Yes, early studies show suprachoroidal injections of triamcinolone can improve vision and reduce swelling in diabetic macular edema, but more research is needed.
Antibodies to Epstein-Barr virus (EBV) proteins, especially EBNA1, and circulating EBV DNA are linked to higher NPC risk.
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, giving a femoral nerve block before surgery reduces rebound pain more effectively than giving it after surgery, according to a 2024 trial.
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, 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, 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, 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.
Yes, prolonged prone positioning (≥24 hours) improves oxygenation in ARDS, but its effect on mortality is uncertain and it increases pressure injury risk.
Research shows long COVID patients have distinct immune signatures compared to healthy people, including increased monocyte activation and signs of immune exhaustion.
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.
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.
