Travel Distance to Subspecialty Clinic and Outcomes in Patients with Fibrotic Interstitial Lung Disease.

Early access to subspecialty care is associated with improved outcomes for patients with fibrotic interstitial lung disease (ILD). Access to ILD care may be limited for patients living far from subspecialty clinics. To test the hypothesis that greater travel distance to access ILD clinical care would be associated with more severe disease at time of referral and worse clinical outcomes.

Is pudendal nerve entrapment a potential cause for weak ejaculation?

Ejaculatory dysfunction is one of the most common complaints of patients with sexual disorders. While it encompasses several ejaculatory disorders, weak ejaculation is seldom described in the literature. Since the pudendal nerve is the main nerve of ejaculation, we aim to hypothesize that pudendal nerve entrapment could be a cause of weak ejaculation, and that pudendal nerve release could contribute to the improvement of the ejaculatory stream.

A system-view of Bordetella pertussis booster vaccine responses in adults primed with whole-cell versus acellular vaccine in infancy.

The increased incidence of whooping cough worldwide suggests that current vaccination against Bordetella pertussis infection has limitations in quality and duration of protection. The resurgence of infection has been linked to the introduction of acellular vaccines (aP), which have an improved safety profile compared with the previously used whole-cell (wP) vaccines. To determine immunological differences between aP and wP priming in infancy, we performed a systems approach of the immune response to booster vaccination.
