Men calling healthline.

OBJECTIVE: To compare data for men who call Healthline for themselves with data from women callers and to use those pilot data to inform strategies to encourage men to use Healthline. SUBJECTS AND METHODS: This was a study examining retrospective data for people calling Healthline in a week in October 2010. Calls from 487 men were compared with those from 487 women. Geocoded data provided deprivation levels. RESULTS: There were fewer men calling than women in all age groups, although younger men were overrepresented. Young men were more acutely unwell than young women or older men. Men called at all times of the day, and call duration was similar to that of women callers. Most men callers were European; men of other ethnic groups were underrepresented compared with women and compared with their representation in the New Zealand population. Men from higher deprivation areas were more likely to call than those from lower deprivation areas. CONCLUSIONS: Compared with women, men underuse Healthline as they do other primary care services. Overall, men are more symptomatic than women; of interest is our observation that among men, the users are likely to be younger, of lower socioeconomic status, and European. Healthline may be an acceptable source of health advice for these men, and it should be considered central in any future initiative addressing men's health.

Characterization of Polydioxanone in Near-Field Electrospinning.

Electrospinning is a popular method for creating random, non-woven fibrous templates for biomedical applications, and a subtype technique termed near-field electrospinning (NFES) was devised by reducing the air gap distance to millimeters. This decreased working distance paired with precise translational motion between the fiber source and collector allows for the direct writing of fibers. We demonstrate a near-field electrospinning device designed from a MakerFarm Prusa i3v three-dimensional (3D) printer to write polydioxanone (PDO) microfibers. PDO fiber diameters were characterized over the processing parameters: Air gap, polymer concentration, translational velocity, needle gauge, and applied voltage. Fiber crystallinity and individual fiber uniformity were evaluated for the polymer concentration and translational fiber deposition velocity. Fiber stacking was evaluated for the creation of 3D templates to guide the alignment of human gingival fibroblasts. The fiber diameters correlated positively with polymer concentration, applied voltage, and needle gauge; and inversely correlated with translational velocity and air gap distance. Individual fiber diameter variability decreases, and crystallinity increases with increasing translational fiber deposition velocity. These data resulted in the creation of tailored PDO 3D templates, which guided the alignment of primary human fibroblast cells. Together, these results suggest that NFES of PDO can be scaled to create precise geometries with tailored fiber diameters for biomedical applications.
