Prostate Cancer Screening and Mortality in Blacks and Whites: A Hospital-based Case-Control Study.

Background: Prostate cancer incidence and mortality are substantially higher in Black than in white men. Prostate cancer screening remains controversial. This study was conducted to assess the impact of, and racial differences in, prostate cancer screening on prostate cancer mortality.

The STarT back screening tool and individual psychological measures: evaluation of prognostic capabilities for low back pain clinical outcomes in outpatient physical therapy settings.

Background: Psychologically informed practice emphasizes routine identification of modifiable psychological risk factors being highlighted.

Objective: The purpose of this study was to test the predictive validity of the STarT Back Screening Tool (SBT) in comparison with single-construct psychological measures for 6-month clinical outcomes.

Design: This was an observational, prospective cohort study.

Associations of serum concentrations of organochlorine pesticides with breast cancer and prostate cancer in U.S. adults.

Background: Organochlorine (OC) pesticides are a group of environmental endocrine disruptors that may be associated with an increased risk for hormone-related cancers including cancers of the breast and prostate. However, epidemiologic evidence is limited and inconsistent.

Objectives And Methods: We used 1999-2004 National Health and Nutrition Examination Survey data to examine associations between serum concentrations of OC pesticides and prostate and breast cancers.

Food groups and renal cell carcinoma: results from a case-control study.

Background: The role of diet in renal cell carcinoma risk has been inconclusive. This study uses an integrative approach to assess the role of food groups and food items in renal cell carcinoma risk.

Design: A case-control study was conducted from 2003-2006.

Smoking, environmental tobacco smoke, and risk of renal cell cancer: a population-based case-control study.

Background: Kidney and renal pelvis cancers account for 4% of all new cancer cases in the United States, among which 85% are renal cell carcinomas (RCC). While cigarette smoking is an established risk factor for RCC, little is known about the contribution of environmental tobacco smoke (ETS) to RCC incidence. This study assesses the role of smoking and ETS on RCC incidence using a population-based case-control design in Florida and Georgia.

Familial aggregation of insulin resistance in first-degree relatives of patients with nonalcoholic fatty liver disease.

Background & Aims: An association between nonalcoholic fatty liver disease (NAFLD) and the insulin resistance (IR) syndrome exists. Familial clustering of IR may support a genetic predisposition to NAFLD or cryptogenic cirrhosis (CC).

Methods: Patients with NAFLD (n = 20) and healthy controls (n = 20) matched for age, sex, and body mass index with at least 4 living relatives and 2 generations of lineage participated in a familial aggregation study.

Risk factors for injury in high school football players.

Background: Many studies have reported the frequency and types of injuries in high school football players. However, few have assessed the relationship between player characteristics and risk of injury.

Purpose: To describe the epidemiologic characteristics of and risk factors for injury in high school football players and to determine whether players' characteristics could be used to predict subsequent injury.

Risk factors for injury in middle school football players.

Background: Little is known about the frequency of or risk factors for injuries in middle school or junior high school football players.

Purpose: To examine the associations of player characteristics (injury history, conditioning, player position, special equipment) and physical parameters (body mass index, weight, height, grip strength) with risk of injury.

Study Design: Prospective cohort study.
