Real questions from health communities, answered with cited research from PubMed and Vellito's article corpus. Plain language, no medical advice. How this works.

For oral and maxillofacial surgery patients, key risk factors for postoperative delirium include age over 65, male sex, alcohol use, smoking, and insomnia.
A large meta-analysis found no significant difference in mortality between anterior and posterior circulation aneurysm locations after aSAH.
Yes, a low Geriatric Nutritional Risk Index (GNRI) is linked to a higher risk of postoperative delirium, with meta-analyses showing about a 60% increase in risk.
Current evidence shows remimazolam does not significantly lower postoperative delirium risk compared to propofol or other sedatives, and may increase risk versus dexmedetomidine.
A phase 2 trial found IV CN-105 safe and feasible, but did not show a significant reduction in postoperative delirium incidence compared to placebo.
Yes, preoperative psychological factors like depression and anxiety can increase your risk of postoperative delirium in older adults.
Yes, switching to an integrase inhibitor may raise the risk of major adverse cardiovascular events, especially in people with low-to-moderate baseline risk, according to a 2024…
Yes, a five-variable model using age, pre-morbid mRS, WFNS grade, modified Fisher grade, and ICH on CT can predict 90-day outcomes after aSAH with good accuracy (AUC 0.868-0.917).
A large meta-analysis found no significant difference in survival between anterior and posterior circulation aneurysm locations after subarachnoid hemorrhage.
Blood tests for oral cancer are not yet accurate enough for routine screening; recent research shows promising but variable results, with some methods achieving ~95% accuracy in…
Smoking and aging strongly increase the risk of having both cataracts and age-related macular degeneration, with a synergistic effect in people over 75.
Children with Post-COVID-19 Condition commonly experience fatigue, exertion intolerance, anxiety, and respiratory symptoms like cough or shortness of breath, often after mild…
A 2022-2024 outbreak in Virginia involved a specific strain of bacteria that caused severe illness and deaths, particularly in adults aged 30-60, with no single common exposure…
COVID-like symptoms can last up to 12 months after a positive or negative test, with fatigue and brain fog being common long-term issues.
Digital cognitive assessments can help track Post-COVID-19 condition by measuring brain function and comparing results to standard tests to see if symptoms like brain fog are…
Children and adolescents with post-COVID-19 condition commonly experience fatigue, lack of concentration, muscle pain, headache, and sleep problems, though symptoms vary and are…
Some long-term symptoms like fatigue, brain fog, and pulmonary embolism are more common after SARS-CoV-2 than other respiratory viruses, but many symptoms appear similar across…
Current research shows no significant link between diabetic retinopathy and age-related macular degeneration, despite both conditions sharing some similar underlying mechanisms.
Yes, machine learning models can predict progression from early to late AMD with moderate accuracy, using imaging and clinical data.
Yes, the CDC updated its meningococcal vaccination rules in 2020 to include new groups and schedules, and later adjusted dosing for the MenB-4C vaccine.
Yes, obstructive sleep apnea may increase your risk for age-related macular degeneration, especially the neovascular (wet) form, though the evidence is mixed.
Yes, mindfulness training, particularly Mindfulness Based Stress Reduction (MBSR), improves quality of life and reduces pain catastrophising in people with fibromyalgia, with…
A 2024 trial found that combining CBT with specialized exercise did not outperform CBT or exercise alone for juvenile fibromyalgia pain disability, though all treatments helped.
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.
