The second sample of youth baseball players were members of eight of the twelve teams participating in the 1995 Dixie Youth World Series.

Breast cancer disparities in South Carolina: early detection, special programs, and descriptive epidemiology.

A discrepancy exists between mortality and incidence rates between African-American and European-American women in South Carolina. The relationship between tumor grade and the estrogen/ progesterone receptor status is different in African-American and European-American women. African-American women with breast cancer should be encouraged to participate in clinical trials, with the goal of identifying biological factors that might facilitate the detection of tumors at an earlier stage and the development of more effective therapies.

Childbirth education for multiple pregnancy: part 2: intrapartum and postpartum considerations.

Women with a multiple pregnancy can expect a different labor and birth course than those with a singleton pregnancy. While the postpartum period is similar to that of families with a singleton, it is likely to be more hectic in families with multiple infants. In addition, a multiple pregnancy increases both maternal and neonatal risks; therefore, women with a multiple pregnancy may experience slight differences in care due to these potential risks, including additional monitoring and treatment.

Childbirth education for multiple pregnancy: part 1: prenatal considerations.

Women with a multiple pregnancy have unique learning needs in preparing for birth. This paper explores the issues relevant to women with a multiple pregnancy to support a positive birth experience. One of the foundations of childbirth education and nursing care is to provide the individual woman and her family with knowledge regarding the birth process, what to expect, and how to cope with labor and birth.

Web Sites that Address Epidural Anesthesia for Childbirth.

Epidural analgesia has become a popular way to reduce pain during labor. Because epidural use is not limited to women who plan its use, but extends to some who originally planned a nonmedicated birth, it is important for the childbirth educator to provide information on this topic to all women. In this column, the authors provide examples of Web sites that address epidural anesthesia.

Planned adolescent pregnancy: themes related to the pregnancy.

Health-care providers need to recognize that not all adolescent pregnancies occur as a result of error. A small subset of adolescents intentionally plan their pregnancy. The purpose of this phenomenological study was to describe the experiences of 14- to 17-year-old pregnant females who had planned their pregnancies.

New Resource from the CDC to Prevent Obesity: Perinatal Implications.

Development of a curriculum to enhance community-based organizations' capacity for effective HIV prevention programming and management.

Community-based organizations (CBOs), particularly minority-based CBOs, are instrumental in the delivery of HIV/AIDS prevention programs and services. Despite a tremendous need, many CBOs lack the capacity to plan, implement, and evaluate targeted prevention interventions to serve culturally diverse populations. This article describes a comprehensive, innovative curriculum for building capacity within CBOs providing HIV prevention programming.

The effect of perceived parental involvement and the use of growth-fostering relationships on self-concept in adolescents participating in gear up.

Adolescence is marked by physical, cognitive, and social changes which affect how individuals perceive themselves. However, individuals do integrate their perceptions with those of significant others. Adolescents' self-concept is influenced by their relationships with family, peers, mentors, and community groups.

Green tea polyphenol (-)-epigallocatechin-3-gallate inhibits cyclooxygenase-2 expression in colon carcinogenesis.

Tea, one of the most widely consumed beverages worldwide, has been shown to have anti-cancer activity in various cancers including colon cancer. It has been demonstrated that overexpression of the inducible isoform of cyclooxygenase (COX-2) occurs during colon tumorigenesis and inhibition of COX-2 by non-steroidal anti-inflammatory drugs (NSAIDs) is chemopreventive. To determine whether the anti-cancer effect associated with green tea impacted COX-2 expression levels, human colorectal cancer cell lines HT-29 and HCA-7, were treated with (-)-epigallocatechin-3-gallate (EGCG), the most abundant and effective polyphenol of green tea.

Gene expression determinants of clinical outcome.

Purpose Of Review: Gene expression profiling of human cancers has produced a large amount of information that could aid physicians in making decisions related to the treatment of their patients. A number of recent studies have identified collections of genes and corresponding expression levels that correlate with the physical appearance and clinical behavior of all common human neoplasms.

Recent Findings: This article will discuss emerging trends of study design and approaches to gene expression signature identification.

Barriers associated with the delivery of Medicare-reimbursed diabetes self-management education.

Purpose: The purpose of this study was to explore the barriers that practitioners face in providing diabetes self-management education (DSME) to Medicare beneficiaries, with a special focus on barriers faced by rural providers.

Methods: Using an e-mail survey, Diabetes Control Program Coordinators (DCPCs) in all US states were asked 3 open-ended questions to understand problems with obtaining American Diabetes Association (ADA) recognition for Medicare reimbursement, differences in obtaining ADA recognition by rural and urban facilities, and facility-level barriers to providing DSME to Medicare patients. Using a mail survey administered to half of ADA-recognized diabetes education centers (DECs), information was collected about perceived barriers to providing DSME in all areas and rural areas.

Drinking locations prior to impaired driving among college students: implications for prevention.

Drinking and driving is perhaps the most serious problem associated with heavy drinking among college students in the United States. In this study, the authors examined drinking locations prior to impaired driving in a college student sample. They administered the Impaired Driving Assessment to 91 college students identified as high risk for drinking and driving.

Effect of exercise duration on plasma endothelin-1 concentration.

Aim: Endothelin-1 (ET-1) is a potent vasoconstricting peptide released mostly from vascular endothelial cells. Isolated exercise sessions of relatively long duration (=or>30 min) have produced increases in plasma ET-1 concentration while shorter exercise sessions usually have not. The purpose of the present study was to verify an effect of exercise duration at a steady work rate on plasma ET-1 concentration.

Application of cross time-frequency analysis to postural sway behavior: the effects of aging and visual systems.

In this paper, the effects of visual feedback and aging on postural sway systems and signals are investigated by analyzing the transient phase difference between "input" and "output" which correspond to center of pressure (COP) and center of mass (COM), respectively. In order to analyze the transient phase difference characteristics of COP and COM, a relatively new cross time-frequency analysis technique that provides time- and frequency-localized phase difference information is utilized. The feedback control process in the postural sway is interpreted in terms of a feedback compensator which is characterized in terms of a phase difference.

Sex cycle modulates cancer growth.

Hypothesis: Among premenopausal women, both post-resection metastatic potential and tumor growth rate are influenced by the menstrual cycle. There is strong support for the former in large retrospective studies of surgical resection timing within the menstrual cycle and the following experiments were conducted to critically evaluate the latter.

Methods: We studied a transplantable breast cancer of C3HeB/FeJ mice (3 studies), and a transplantable methylcholantherene A induced sarcoma of CD2F1 mice (2 studies).

Evaluating the sustainability of SPARK physical education: a case study of translating research into practice.

Dissemination and sustainability of evidence-based physical education programs (PE) has been studied rarely. The sustainability of a health-related PE program (SPARK) was independently evaluated in 111 elementary schools in 7 states. Surveys were mailed to schools that had received SPARK curriculum books, training and follow-up (response rate = 47%).

Speciation of chromium via laser-induced breakdown spectroscopy of ion exchange polymer membranes.

A new method for the speciation of ng/mL concentrations of Cr(III) and Cr(VI) solutions with analysis by laser-induced breakdown spectroscopy (LIBS) is reported. Speciation is achieved by pre-concentration of the chromium onto commercially available cation exchange polymer membranes. Chromium(III) is removed directly by cation exchange; chromium(VI) in the filtrate is reduced to Cr(III) and concentrated onto a second cation exchange membrane, affording independent measurement of both species.
