Complementary therapy for addiction: "drumming out drugs". (49/492)

OBJECTIVES: This article examines drumming activities as complementary addiction treatments and discusses their reported effects. METHODS: I observed drumming circles for substance abuse (as a participant), interviewed counselors and Internet mailing list participants, initiated a pilot program, and reviewed literature on the effects of drumming. RESULTS: Research reviews indicate that drumming enhances recovery through inducing relaxation and enhancing theta-wave production and brain-wave synchronization. Drumming produces pleasurable experiences, enhanced awareness of preconscious dynamics, release of emotional trauma, and reintegration of self. Drumming alleviates self-centeredness, isolation, and alienation, creating a sense of connectedness with self and others. Drumming provides a secular approach to accessing a higher power and applying spiritual perspectives. CONCLUSIONS: Drumming circles have applications as complementary addiction therapy, particularly for repeated relapse and when other counseling modalities have failed.  (+info)

Human milk secretory antibodies against attaching and effacing Escherichia coli antigens. (50/492)

Secretory immunoglobulin A (sIgA) is a primary factor responsible for preventing attachment of enteropathogens to gut epithelium in breastfeeding infants. We compared the frequency of sIgA to major surface antigens of enterohemorrhagic Escherichia coli (EHEC) in milk of 123 women from the United States and Mexico to determine whether regional differences existed in the frequency of antibodies to these surface antigens. In both groups of women, milk commonly has sIgA against various EHEC lipopolysaccharides, EspA, EspB, intimin, and less frequently against Shiga toxin. The study suggests that persons living in the United States are exposed to attaching/effacing enteropathogens more frequently than is generally assumed. The low frequency of antibodies to Stx1 (in 12% of Mexican and in 22% of U.S. samples) suggests that the rare appearance of hemolytic uremic syndrome in adults is not due to neutralization of toxin at the gut level. Only anti-EspA is found in most milk samples from both populations of women. EspA may represent a useful target for an immunization strategy to prevent EHEC disease in humans.  (+info)

Computation and visualization of regional-scale forest disturbance and associated dissolved nitrogen export from Shenandoah National Park, Virginia. (51/492)

Long-term watershed research conducted in Shenandoah National Park (SNP) in Virginia and elsewhere in the eastern U.S. indicates that annual export of dissolved nitrogen (N) from gaged forested watersheds to surface waters increases dramatically in response to vegetation disturbances. Dissolved N leakage is a common, well-documented response of small forested watersheds to logging in the larger region, while recent defoliation outbreaks of the gypsy moth ( Lymantria dispar) larva in the deciduous forests of SNP have been shown to generate similar biogeochemical responses. A recent modeling analysis further suggests that a parsimonious, empirical, unit N export response function (UNERF) model can explain large percentages of the temporal variation in annual N export from a group of small gaged forested watersheds in the years following disturbance. The empirical UNERF modeling approach is completely analogous to the unit hydrograph technique for describing storm runoff, with the model representing annual N export as a linear deterministic process both in space and in time. The purposes of this analysis are to (1) test the applicability of the UNERF model using quarterly streamwater nitrate data from a group of ungaged watersheds in SNP; (2) demonstrate a park-wide application of a regional UNERF model that references the geographic distributions of bedrock geology and the timing and extent of gypsy moth defoliation over the entire SNP area; and (3) visualize the temporal and spatial patterns in vegetation disturbance and annual dissolved N export through the use of computer animation software. During water year 1992, the year of peak defoliation, our modeling study suggests that park-wide export had transiently increased by 1700% from a baseline rate of about 0.1 kg/ha/year. SNP forests appear to be characteristic of other N-limited second-growth forests in the eastern U.S. that leak little N under undisturbed conditions, despite receiving relatively large inputs of N from atmospheric deposition sources. Vegetation disturbances can apparently cause major changes in N input-output balances with potentially important ramifications for low-order forest streams and downstream receiving waters.  (+info)

Motivational intervention to reduce alcohol-exposed pregnancies--Florida, Texas, and Virginia, 1997-2001. (52/492)

Prenatal alcohol use is a threat to healthy pregnancy outcomes for many U.S. women. During 1999, approximately 500,000 pregnant women reported having one or more drinks during the preceding month, and approximately 130,000 reported having seven or more alcohol drinks per week or engaging in binge drinking (i.e., five or more drinks in a day). These heavier drinking patterns have been associated with fetal alcohol syndrome (FAS) and alcohol-related neurodevelopmental disorders (ARND). Lower levels of alcohol consumption (i.e., fewer than seven drinks per week) also have been associated with measurable effects on children's development and behavior. Although the majority of women reduce their alcohol use substantially when they realize they are pregnant, a large proportion do not realize they are pregnant until well into the first trimester and, therefore, might continue to drink alcohol during this critical period of fetal development. To reduce alcohol-exposed pregnancies, CDC initiated a multisite pilot study (phase I clinical trial) in 1997 to investigate the use of a dual intervention focused on both alcohol-use reduction and effective contraception among childbearing-aged women at high risk for an alcohol-exposed pregnancy (Project CHOICES). This report describes the association between baseline drinking measures and the success women have achieved in reducing their risk for an alcohol-exposed pregnancy. The analysis compares the impact of the motivational intervention at 6-month follow-up on women drinking at high-, medium-, and low-risk drinking levels. The findings indicate that although 69% of the women in the study reduced their risk for an alcohol-exposed pregnancy, women with the lowest baseline drinking measures achieved the highest rates of outcome success, primarily by choosing effective contraception and, secondarily, by reducing alcohol use. Women with higher baseline drinking measures chose both approaches equally but achieved lower success rates for reducing their risk for an alcohol-exposed pregnancy. A randomized controlled trial of the motivational intervention is under way to further investigate outcomes of the phase I study.  (+info)

Using hospital discharge files to enhance cancer surveillance. (53/492)

Use of the traditional mechanism for cancer surveillance, hospital-based registries, may limit ascertainment of incident cases. In this study, the authors evaluated the ability of a statewide hospital discharge file (HDF) to enhance central cancer registry reporting. Incident cancers from a Virginia cancer registry were linked with an HDF for 1995. Medical record abstractions for over 2,000 cancers verified HDF and registry data. There were 19,740 unique cases ascertained from the two combined data sources. The registry captured approximately 83% of cases, while the HDF captured 62%. Although the HDF missed a substantial number of registry cases, the HDF positive predictive value for identifying the correct cancer site was 94%. Logistic regression was used to identify significant characteristics of cases likely to be captured only by the HDF; these characteristics included hospital cancer program certification, the position of the cancer diagnosis on the claim, and cancer surgery. This study represents the evaluation of a novel approach to enhancing registry completeness and accuracy using statewide HDFs. The results strongly suggest that neither a central cancer registry nor an HDF is a sufficient source for complete capture of cases. Using HDFs to supplement a central cancer registry may be a valuable and efficient method for improving registry completeness of reporting.  (+info)

Characterization of the major antigenic protein 2 of Ehrlichia canis and Ehrlichia chaffeensis and its application for serodiagnosis of ehrlichiosis. (54/492)

Canine monocytic ehrlichiosis, caused by Ehrlichia canis or Ehrlichia chaffeensis, can result in clinical disease in naturally infected animals. Coinfections with these agents may be common in certain areas of endemicity. Currently, a species-specific method for serological diagnosis of monocytic ehrlichiosis is not available. Previously, we developed two indirect enzyme-linked immunosorbent assays (ELISAs) using the major antigenic protein 2 (MAP2) of E. chaffeensis and E. canis. In this study, we further characterized the conservation of MAP2 among various geographic isolates of each organism and determined if the recombinant MAP2 (rMAP2) of E. chaffeensis would cross-react with E. canis-infected dog sera. Genomic Southern blot analysis using digoxigenin-labeled species-specific probes suggested that map2 is a single-copy gene in both Ehrlichia species. Sequences of the single map2 genes of seven geographically different isolates of E. chaffeensis and five isolates of E. canis are highly conserved among the various isolates of each respective ehrlichial species. ELISA and Western blot analysis confirmed that the E. chaffeensis rMAP2 failed to serologically differentiate between E. canis and E. chaffeensis infections.  (+info)

Contribution of selected metabolic diseases to early childhood deaths--Virginia, 1996-2001. (55/492)

Sudden infant death syndrome (SIDS), or the death of an infant aged <1 year that remains unexplained after a thorough investigation, is the third most common cause of death among infants in the United States. Sudden, unexplained deaths also occur among children aged >/=1 year; however, the number of these deaths is not well documented. Certain cases of SIDS and sudden unexplained death beyond infancy might be attributable to complications of unrecognized metabolic diseases. Tandem mass spectrometry (tandem MS) can be used to screen for several of these disorders. Despite the low prevalence of these diseases, newborn screening for these disorders has been found to compare favorably with the cost of other screening programs. However, the contribution of these diseases to early childhood deaths is not well understood. To determine the proportion of sudden, unexpected early childhood deaths associated with selected metabolic diseases, CDC, the Office of the Chief Medical Examiner (ME) in Virginia, and a private laboratory conducted a population- based study. This report summarizes the results of the study, which indicate that 1% of children had a positive postmortem metabolic screen using tandem MS. Of the eight children with positive screening tests, seven might have had improved outcomes had they been identified and treated during the newborn period. The use of tandem MS in newborn screening programs could offer an opportunity to prevent early childhood mortality.  (+info)

Current issues in the design of academic health sciences libraries: findings from three recent facility projects. (56/492)

Planning a new health sciences library at the beginning of the twenty-first century is a tremendous challenge. Technology has radically changed the way libraries function in an academic environment and the services they provide. Some individuals question whether the library as place will continue to exist as information becomes increasingly available electronically. To understand how libraries resolve programming and building design issues, visits were made to three academic health sciences libraries that have had significant renovation or completed new construction. The information gathered will be valuable for planning a new library for the University of Colorado Health Sciences Center and may assist other health sciences librarians as they plan future library buildings.  (+info)
