The National Conference on Health Disparities Student Research Forum.

The annual National Conference on Health Disparities (NCHD) was launched in 2000. It unites health professionals, researchers, community leaders, and government officials, and is a catalyzing force in developing policies, research interventions, and programs that address prevention, social determinants, health disparities, and health equity. The NCHD Student Research Forum (SRF) was established in 2011 at the Medical University of South Carolina to build high-quality biomedical research presentation capacity in primarily underrepresented undergraduate and graduate/professional students.

Patterns of Phylogenetic Diversity of Subtropical Rainforest of the Great Sandy Region, Australia Indicate Long Term Climatic Refugia.

Australia's Great Sandy Region is of international significance containing two World Heritage areas and patches of rainforest growing on white sand. Previous broad-scale analysis found the Great Sandy biogeographic subregion contained a significantly more phylogenetically even subset of species than expected by chance contrasting with rainforest on white sand in Peru. This study aimed to test the patterns of rainforest diversity and relatedness at a finer scale and to investigate why we may find different patterns of phylogenetic evenness compared with rainforests on white sands in other parts of the world.

The fluctuation of nocturia in men with lower urinary tract symptoms allocated to placebo during a 12-month randomized, controlled trial.

Purpose: We determined the fluctuation of nocturia in a 12-month period in men with lower urinary tract symptoms.

Materials And Methods: Men with lower urinary tract symptoms were allocated to the placebo arm of the United States Department of Veterans Affairs Cooperative Studies Program Benign Prostatic Hyperplasia Study. Reported nocturia frequency using the American Urological Association Symptom Index was collected at 6 time points (2, 4, 13, 26, 39 and 52 weeks).

Brainstem encephalitis: an unusual presentation of herpes simplex virus infection.

Herpes simplex virus (HSV) encephalitis has a predilection for the temporal and frontal lobes but occasionally affects the brainstem. We describe a patient who developed HSV brainstem encephalitis that progressed to quadriplegia. Using MEDLINE, we conducted a comprehensive review of other published cases of HSV brainstem encephalitis.

Cerebral malaria is associated with low levels of circulating endothelial progenitor cells in African children.

Damage to the cerebral microvasculature is a feature of cerebral malaria. Circulating endothelial progenitor cells are needed for microvascular repair. Based on this knowledge, we hypothesized that the failure to mobilize sufficient circulating endothelial progenitor cells to the cerebral microvasculature is a pathophysiologic feature of cerebral malaria.

Five-alpha-reductase expression in benign and malignant urothelium: correlation with disease characteristics and outcome.

Objectives: To evaluate 5-alpha-reductase (5alphaR) expression in benign and malignant urothelium and to assess the relationship between 5alphaR expression and tumor stage, tumor grade, and clinical outcome in patients with urothelial carcinoma/transitional cell carcinoma.

Methods: We performed immunohistochemistry for 5alphaR on 53 urothelial specimens from 36 patients with transitional cell carcinoma treated at our institution between June 2002 and July 2003. For each tumor and the adjacent nontumor urothelium, a semiquantitative staining score was calculated.

Nephroscreen: a diagnostic test for predicting acute renal failure?

Acute renal failure is a frequent and often fatal complication of hospitalized patients. While the risk of acute renal failure among select patient groups is well recognized, physicians currently rely on diagnostic tests such as changes of serum creatinine and indirect assessment of the glomerular filtration rate to diagnose acute renal failure. Although these parameters capture the degree of kidney function lost, they are not warning signs of evolving kidney injury.

Young males' sexual education and health services.

This study examined the basis for one hospital's decision to restructure its teen family planning clinical services. We examined results of surveys conducted from 1998 to 2003 with more than 2000 mostly African American eighth-grade boys. Most young males wanted to postpone sexual intercourse, but an even greater percentage were willing to use a method of protection.

Nurses' use of alcohol and other drugs: findings from a national probability sample.

This study examined the prevalence of alcohol and other drug (AOD) use among nurses in the 1984 National Longitudinal Survey of Youth (NLSY) using methods similar to those employed in a study comparing nurses and nonnurses from the 1980-1984 Epidemiological Catchment Area program (ECA). Conditional logistic regression was used to estimate the degree to which AOD use was associated with occupation. Results indicating that substance use is unrelated to occupation lend support to earlier findings from the ECA.
