Real questions from health communities, answered with cited research from PubMed and Vellito's article corpus. Plain language, no medical advice. How this works.
Social factors like structural racism, limited healthcare access, and chronic stress increase preeclampsia risk in Black women, interacting with genetic and biological pathways.
Yes, exposure to air pollution (PM2.5, PM10, NO2) and noise during childhood is linked to a small increased risk of ADHD, though the effect is modest and more research is needed.
Current evidence shows transcranial direct current stimulation (tDCS) does not significantly reduce core ADHD symptoms in children, though some studies suggest possible benefits…
No, current evidence does not show that epidural analgesia during birth causes neurodevelopmental disorders like ADHD or autism in children.
Yes, mental health issues like depression can reduce HIV medicine success in PTSD patients by worsening adherence to antiretroviral therapy and viral suppression.
NK cell immunotherapy for solid tumors faces major hurdles: poor tumor infiltration, the immunosuppressive tumor microenvironment, antigen heterogeneity, and limited persistence…
Yes, a monoclonal stool antigen test is a reliable non-invasive tool for detecting H. pylori in chronic atrophic gastritis, with high specificity and strong diagnostic consistency.
Yes, COMPASS CBT is designed for lay providers in Peru, with a pilot trial underway to test its effectiveness for PTSD in Venezuelan migrants.
Yes, a 2025 meta-analysis found vonoprazan-based therapies achieve 94% eradication in Asian patients, but real-world rates vary.
Yes, watching uncensored traumatic videos is linked to worse PTSD symptoms, even in people not directly exposed to the trauma.
In children aged 4–13 years, studies compare triple therapy (PPI + amoxicillin + clarithromycin or PPI + metronidazole + clarithromycin) versus bismuth-containing quadruple…
For patients under 50, knee implants (total knee arthroplasty) show 87% survival at 10+ years, with aseptic loosening as the main reason for revision.
Clarithromycin resistance significantly lowers H. pylori eradication success in children, but bismuth-based quadruple therapy or tailored regimens can overcome this resistance.
Yes, sensors can detect frailty in retired adults aged 65+ by measuring gait, balance, grip strength, and other physiological signals, with studies showing high accuracy.
Recent reviews link NAFLD to periodontitis, type 2 diabetes, obesity, cardiovascular disease, and bile acid-related conditions like IBS-D and CRC.
Yes, elevated testosterone levels, especially free and bioavailable testosterone, are linked to a higher risk of NAFLD, particularly in postmenopausal women and women with PCOS.
Yes, bismuth quadruple therapy works better than triple therapy for H. pylori eradication in children, with higher success rates especially when clarithromycin resistance is…
Single-cell RNA sequencing helps researchers study NAFLD by revealing which liver cell types drive disease progression and identifying new biomarkers for diagnosis.
A pilot study suggests ketotifen may improve liver fat and fibrosis more than vitamin E in NAFLD, but more research is needed.
Exosomal non-coding RNAs regulate osteoarthritis by controlling inflammation, cartilage breakdown, and joint cell communication, and show promise as biomarkers and therapies.
Yes, frailty significantly increases the likelihood of depression in adults with cancer, with frail patients having nearly six times higher odds of depressive symptoms.
Genes linked to osteoarthritis in meniscus and cartilage include 27 meniscus-specific, 28 shared, and 20 cartilage-specific causal genes, such as VEGFA and CLEC18A, identified…
Yes, higher alpha-Klotho levels are linked to lower frailty risk, with a meta-analysis showing 39% lower odds of frailty per unit increase.
Yes, early research shows engineered exosomes can target cartilage, reduce inflammation, and promote repair in osteoarthritis, but human trials are still needed.
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.
