Randomized Controlled Trial Multicenter Study Comparative Study
A 52-week trial comparing briakinumab with methotrexate in patients with psoriasis.
Briakinumab is a monoclonal antibody against the p40 molecule shared by interleukin-12 and interleukin-23, which is overexpressed in psoriatic skin lesions. We assessed the efficacy and safety of briakinumab as compared with methotrexate in patients with psoriasis. ⋯ Briakinumab showed higher efficacy than methotrexate in patients with moderate-to-severe psoriasis. Serious infections and cancers occurred more frequently with briakinumab, but the differences were not significant. (Funded by Abbott Laboratories; ClinicalTrials.gov number, NCT00679731.).

Randomized Controlled Trial Multicenter Study
HPV vaccine against anal HPV infection and anal intraepithelial neoplasia.
The rate of anal cancer is increasing among both women and men, particularly men who have sex with men. Caused by infection with human papillomavirus (HPV), primarily HPV type 16 or 18, anal cancer is preceded by high-grade anal intraepithelial neoplasia (grade 2 or 3). We studied the safety and efficacy of quadrivalent HPV vaccine (qHPV) against anal intraepithelial neoplasia associated with HPV-6, 11, 16, or 18 infection in men who have sex with men. ⋯ Use of the qHPV vaccine reduced the rates of anal intraepithelial neoplasia, including of grade 2 or 3, among men who have sex with men. The vaccine had a favorable safety profile and may help to reduce the risk of anal cancer. (Funded by Merck and the National Institutes of Health; ClinicalTrials.gov number, NCT00090285.).

The major sites of obstruction in chronic obstructive pulmonary disease (COPD) are small airways (<2 mm in diameter). We wanted to determine whether there was a relationship between small-airway obstruction and emphysematous destruction in COPD. ⋯ These results show that narrowing and disappearance of small conducting airways before the onset of emphysematous destruction can explain the increased peripheral airway resistance reported in COPD.
