Polyuria contributes to bladder overdistention, which confounds both lower and upper urinary tract management in individuals having a spinal cord injury (SCI). Bladder overdistention post-SCI is one of the most common triggers for autonomic dysreflexia, a potentially life-threatening condition. Post-SCI polyuria is thought to result from loss of vascular tone in the lower extremities, leading to edema and subsequent excess fluid, resulting in polyuria. ⋯ Step training (30 min/day, 6 days/week) did not alleviate polyuria in the moderate SCI contusion group. These results indicate that (1) mild injuries retaining weight-bearing locomotion that should have mild, if any, edema/loss of vascular tone still exhibit severe polyuria, and (2) step training was unable to reduce post-SCI polyuria. Taken together, these results indicate that the current mechanistic hypothesis of post-SCI polyuria may be incomplete.

Comparative StudyThe influence of loan repayment on rural healthcare provider recruitment and retention in Colorado.
There is an ongoing shortage of rural healthcare providers relative to urban healthcare providers worldwide. Many strategies have been implemented to increase the distribution of rural healthcare providers, and financial incentives such as loan repayment programs have become popular means to both recruit and retain healthcare providers in rural communities. Studies detailing the effects of such programs on rural provider recruitment and retention are limited. The objective of this study was to assess the influence of loan repayment and other factors on the recruitment and retention of healthcare providers in rural Colorado, USA, and to compare the motivations and attitudes of these rural providers with their urban counterparts. ⋯ Loan repayment programs targeting rural Colorado usually enroll providers who would have worked in a rural area regardless of loan repayment opportunities, but are likely to play a role in providers' choice of specific rural community for practice. They also appear to have a limited but important influence on rural provider retention, though financial concerns are generally less influential for non-retained rural providers than are family preferences and professional dissatisfaction.

The overall suicide rate in the U.S. increased by 6% between 1981 and 1986 and declined by 18% between 1986 and 1999. Detailed descriptions of recent trends in suicide are lacking, especially with regard to the method of suicide. Information is needed on the major changes in rates of suicide in specific population groups in recent years (1999-2005). ⋯ The differential increases by age, race, gender, and method underscore a change in the epidemiology of suicide.Whites aged 40-64 years have recently emerged as a new high-risk group for suicide. Although firearms remain the most common method of suicide, the notable increases in suicide by poisoning in men and hanging/suffocation in women deserve prevention attention [corrected].

Vertebral hemangioma (VH) is considered to be a benign lesion of bone with a rich vasculature. Most incidentally discovered hemangiomas are asymptomatic. Percutaneous vertebroplasty (PVP) has demonstrated efficacy in the treatment of symptomatic thoracic and lumbar VHs. To our knowledge, the reports concerning PVP on symptomatic cervical VHs are quite rare. ⋯ Short-term results indicate that PVP appears to be an effective and safe treatment for symptomatic cervical VHs.

Preterm infants are at increased risk to develop insulin resistance and high blood pressure. The influence of growth during childhood is not well established. ⋯ Young adults born preterm have lower insulin sensitivity and higher blood pressure than controls. Increments in height and weight during childhood are associated with lower insulin sensitivity and higher blood pressure in adulthood.
