Example Output: What group was T. Jerome Overbeck a member of?

Example Input: The nationwide prevalence of latent tuberculosis infection (LTBI) in Italian patients with psoriasis has never been investigated. To estimate the nationwide prevalence of LTBI in Italian patients with psoriasis who are candidates for systemic treatment. Data were obtained from the Psocare Registry on those patients (n=4946) with age >18years, systemic treatment at entry specified and tuberculin skin test (TST) performed according to the Mantoux method. LTBI diagnosis was based on a positive TST result in the absence of any clinical, radiological or microbiological evidence of active tuberculosis. Latent tuberculosis infection was diagnosed in 83% of patients with psoriasis (409 of 4946). The prevalence of LTBI was lower in patients on biologics than in those on conventional systemic treatments, ranging from 43% (19 of 444) of patients on adalimumab to 31% (eight of 26) of those on psoralen-ultraviolet A (P<005). Independent factors associated with LTBI were male sex [odds ratio (OR) 130, 95% confidence interval (CI) 104-162; P=002], age over 55years (OR 293, 95% CI 218-393; P<0001) and being entered into a conventional treatment (OR 383, 95% CI 310-474; P<0001). Positive history of tuberculosis was seen in 1% of patients (n=49). The nationwide prevalence of LTBI in Italian patients with psoriasis candidate to systemic treatment is high, and screening is recommended prior to biological treatment.
Example Output: The Mantoux test detects what latent infection/disease?

Example Input: The efficacy of the BD GeneOhm methicillin-resistant Staphylococcus aureus (MRSA) assay was assessed by analyzing nasal swabs and swabs from other body sites for the presence of MRSA in a low-prevalence area. From 681 patients with a high risk for MRSA carriage, 1,601 specimens were collected and transported in Amies agar. After discordant analysis, the sensitivity, specificity, positive predictive value, and negative predictive value of the BD GeneOhm MRSA assay were 84.3%, 99.2%, 88.4%, and 98.9%, respectively, compared to culture.
Example Output:
What is MRSA?
