Relevant information for clinical decision-making in a wide spectrum of diseases includes the extent to which sexual function is intact, how important it is to preserve sexual capacity and whether waning sexual function causes distress. Little information is available on elderly men. We aimed to obtain this basic information. Radiumhemmet's Scale of Sexual Function was posted to 435 randomly se...
Polio eradication is on the cusp of success, with only a few regions still maintaining transmission. Improving our understanding of why some regions have been successful and others have not will help with both global eradication of polio and development of more effective vaccination strategies for other pathogens. To examine the past 25 years of eradication efforts, we constructed a transmissio...
Because of increased numbers of recorded pertussis cases in the United States, this study sought to understand the role of nonmedical vaccine exemptions and waning immunity may have had on the resurgence of pertussis in the United States at the community level. We used geospatial scan statistics, SaTScan, version 9.4, to analyze nonmedical vaccine exemptions of children entering kindergarten in...
vaccine has been reported as approximately 80%, which is considered inadequate to provide population protection. Previous studies have shown that the effectiveness of 2 doses of vaccine is from 88% to 95%. The estimated herd immunity threshold for mumps ranges from 88% to 92%. Although there was no single explanation for this outbreak, multiple factors may have contributed; these factors includ...
The oscillatory properties of single thalamocortical neurons were investigated by using a Hodgkin-Huxley-like model that included Ca2+ diffusion, the low-threshold Ca2+ current (lT) and the hyperpolarization-activated inward current (lh). lh was modeled by double activation kinetics regulated by intracellular Ca2+. The model exhibited waxing and waning oscillations consisting of 1-25-s bursts o...
