Can breathwork reduce stress and anxiety in paramedic students with insomnia?

Yes, a 12-week RCT found that slow diaphragmatic breathwork significantly reduced stress, anxiety, and insomnia in paramedic students.

Do oral bacteria change as periodontitis gets worse in Korean adults?

Yes, oral bacteria change as periodontitis worsens in Korean adults, with higher diversity and specific bacterial shifts seen in advanced stages.

Gastroenterology

How does oxidative stress affect the body in people with periodontitis?

In periodontitis, oxidative stress amplifies inflammation, damages tissues, and drives bone loss by overwhelming the body's antioxidant defenses.

Is there a connection between periodontitis and systemic health disorders?

Yes, periodontitis is linked to several systemic disorders like cardiovascular disease, diabetes, and liver disease, but direct causation is not proven.

Can having periodontitis increase my risk for liver disease or cancer?

Yes, periodontitis may increase the risk of liver disease and liver cancer, likely through systemic inflammation and bacterial spread, but direct causation is not proven.

Psychiatry

Does adding high-frequency rTMS and exercise reduce negative emotions in methamphetamine use disorder?

Yes, a 2024 trial found that adding high-frequency rTMS to exercise significantly reduced depression, anxiety, and craving in methamphetamine use disorder compared to exercise…

Gastroenterology

What is the link between periodontitis and non-alcoholic fatty liver disease?

Research is mixed: some reviews suggest periodontitis may worsen NAFLD through the oral-gut-liver axis, but a large meta-analysis found no clear association.

Gastroenterology

Does subgingival chemical irrigation help treat periodontitis better than standard care?

No, subgingival chemical irrigation does not provide additional benefit over standard non-surgical periodontal treatment alone for periodontitis.

Is there a genetic variant linked to lupus nephritis risk in Chinese Han populations?

Yes, the rs80213143 variant in LOC100130476 is linked to lupus nephritis risk in Chinese Han populations, with the C allele associated with more severe kidney involvement.

Does having the CYP2C19*2 gene variant protect against cyclophosphamide side effects in lupus nephritis?

Yes, the CYP2C19*2 variant is linked to reduced cyclophosphamide toxicity in lupus nephritis, based on a meta-analysis showing a protective effect.

Do complement pathways cause kidney injuries in patients with lupus nephritis?

Yes, complement pathways — especially the classical and alternative pathways — contribute to kidney injury in lupus nephritis by driving inflammation and tissue damage after…

Infectious Disease

What are the new Hepatitis A immunization recommendations for the United States?

New recommendations focus on vaccinating adults at risk, including those who use drugs, are homeless, or have chronic liver disease, due to a major shift in how the virus spreads.

How this works

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.

This is not medical advice. Always speak with your own doctor before making decisions about your health.
