Abstract

Objective. Residential drug treatment units are uniquely situated to provide HIV testing and counseling to their patients. This article examines the extent to which residential drug treatment units in the United States provide HIV testing on-site, and identifies organizational and institutional characteristics that differentiate units in which on-site HIV testing is available from those in which it is not. Methods. The analyses use data collected in telephone interviews with unit managers from a random nationwide sample (N=138) of residential drug treatment units in 2001. Results. About half (48.6%) of the residential drug treatment units made HIV testing available to their patients on-site. Residential units were significantly more likely to make on-site testing available if they were larger (i.e., had a greater number of patients treated each month or had a greater number of staff that provided direct patient services) and if they were publicly rather than privately owned. Provision of on-site HIV testing was significantly correlated with having a medical orientation, i.e., with being operated by a hospital, with the unit viewing itself as patients' primary medical provider, or with providing medical care to the patients either on-site or at another part of the same treatment agency. Conclusion. In view of the critical importance of HIV testing for individuals who use illicit drugs and the existence of a simplified testing protocol involving saliva samples (eliminating the need for phlebotomy), units that do not have a medical orientation should be encouraged to make HIV testing available on-site.

Abstract

Objective: To determine strategies to overcome barriers to HIV testing among persons at risk. Methods: We developed a survey that elicited testing motivators, barriers, and preferences for new strategies among 460 participants at a needle exchange, three sex venues for men who have sex with men, and a sexually transmitted disease clinic. Results: Barriers to testing included factors influenced by individual concern (fear and discrimination); by programs, policies, and laws (named reporting and inability to afford treatment); and by counseling and testing strategies (dislike of counseling, anxiety waiting for results, and venipuncture). The largest proportions of participants preferred rapid testing strategies, including clinic-based testing (27%) and home selftesting (20%); roughly equal proportions preferred oral fluid testing (18%), urine testing (17%), and standard blood testing (17%). One percent preferred home specimen collection. Participants who had never tested before were significantly more likely to prefer home self-testing compared with other strategies. Blacks were significantly more likely to prefer urine testing. Conclusions: Strategies for improving acceptance of HIV counseling and testing include information about access to anonymous testing and early treatment. Expanding options for rapid testing, urine testing, and home self-testing; providing alternatives to venipuncture; making pretest counseling optional; and allowing telephone results disclosure may encourage more persons to learn their HIV status.

Abstract

PURPOSE: To present the theoretical background for lifestyle change interventions in the prevention and management of type 2 diabetes and to provide pragmatic strategies for advanced practice nurses (APNs) to incorporate such interventions into their practices. DATA SOURCES: Selected scientific literature and the Internet. CONCLUSIONS: There is an epidemic of obesity and type 2 diabetes among adults in the United States. Preventing or managing these health conditions requires significant lifestyle changes by individuals. IMPLICATIONS FOR PRACTICE: APNs are in a key role to deliver lifestyle change interventions, particularly in the primary care setting. Strategies to assist APNs with lifestyle change counseling include (a) assessment, (b) mutual decision making, (c) referral to education programs, (d) individualized treatment goals, (e) strategies to assist with problem solving, (f) continuing support and encouragement, (g) relapse prevention, and (h) ongoing follow-up.

Abstract

Hepatitis C virus (HCV) has reached epidemic proportions among drug users, and drug programs are in a unique position to provide each of their patients with HCV education. Using a nationwide sample (N= 434) of drug treatment programs, we report the results of a logistic regression analysis that differentiates programs providing HCV education to all of their patients versus programs that do not. Fifty-four percent of the programs provide HCV education to all of their patients. Programs are about four and a half times as likely to provide HCV education to all patients if they dispense methadone; almost four times as likely to provide this service if they educate most of their staff about HCV; twice as likely if they are residential; and almost twice as likely if they conduct HIV testing on-site. Our findings indicate that there is a need to increase HCV educational services in drug treatment programs.

Abstract

Psychosocial issues are a major part of palliative treatment, yet, due to inadequate training, physicians are often ill-prepared to address them. Twenty physicians were interviewed about the importance they placed on psychosocial issues and the perceptions they had of their role in addressing them. Several respondents felt psychosocial issues were important because they affect physical issues, enable holistic care, enhance relationships, impact care decisions, and can reduce patient and family stress. Other respondents did not feel psychosocial issues were their responsibility due to time constraints, their focus on physical care, their lack of expertise in this area, the patients' preferences for attending physicians, and a sense on the part of house staff physicians of not yet being "real" doctors. Collaboration with other hospital staff helped overcome some of these obstacles. Since physicians must often provide psychosocial care, improved training in addressing psychosocial issues is indicated.

Abstract

The authors’ research group published a major article in October 2002 showing a strong effect of nurse staffing on both patient outcomes and factors related to nurse turnover in 168 Pennsylvania hospitals. This article reviews major design elements and findings of the study and discusses policy implications of this research. Even though evidence is mounting that hospital staffing is a public health issue, regulation of staffing levels remains controversial. Higher quality staffing data that incorporate information about patients’ needs for nursing care are required for better administrative decision-making and research purposes. That the current nurse shortage is occurring in an era of renewed concerns about safety in hospitals offers unique opportunities for developing public policy to remedy problems with staffing and other long-standing workplace environment issues in hospital nursing.

Abstract

Background: A paucity of epidemiologic research exists concerning the co-occurrence of birth defects and mental retardation (MR). Study of this co-occurrence may yield important clues about the causes of both. Objective: To examine the co-occurrence of birth defects and MR, taking into consideration the type of birth defect, level of MR, co-occurrence of MR with other developmental disabilities, and individual and maternal factors. Design: A retrospective cohort study of infants born in the California Central Valley with and without a structural birth defect by 1 year of age, and with or without MR by 7 to 9 years of age. Setting and Participants: One-year survivors (N = 119556) born in nonmilitary hospitals in 8 California counties between January 1, 1992, and December 31, 1993, for whom information about birth defects was recorded within the first year of life. Main Outcome Measure: Diagnosis of MR by age 7 years considered as being mild or severe and as occurring without other developmental disabilities (isolated MR) or as occurring with other developmental disabilities, including cerebral palsy, epilepsy, or a pervasive developmental disorder. Results: Children with birth defects were nearly 27 times more likely to have MR by 7 years of age compared with children without a diagnosed birth defect regardless of type of defect (prevalence ratio, 26.8; 95% confidence interval, 22.7-31.7). Among those with birth defects, children with Down syndrome (prevalence ratio, 211.7; 95% confidence interval, 171.3-261.5) and children with sex chromosomal defects (prevalence ratio, 57.4; 95% confidence interval, 23.7-138.6) were at the highest risk for MR. Children with nonchromosomal defects, including central nervous system defects and all types of organ and system defects, were at substantially increased risk for all levels of MR. Risks of MR among children with Down syndrome and nonchromosomal defects were not substantially altered when adjusted for individual and maternal factors. Conclusions: Children with chromosomal and other structural birth defects are at a substantially increased risk for having MR by 7 years of age compared with children born without a birth defect. Children with birth defects are at an especially increased risk for having severe MR and MR occurring independently of other developmental disabilities.

Abstract

Puerto Rican drug users both in New York and Puerto Rico have disproportionately high rates of HIV/AIDS. This paper derives findings from the ARIBBA Project--a dual site study of HIV risk behaviour determinants among Puerto Rican injection drug users and crack smokers, conducted in East Harlem, NY and Bayamón, PR. Qualitative data collected in focus groups, interviews and observations revealed significant differences in sexual risk behaviours, perceptions of risks and cultural/behavioural norms between the two locations, which were supported by the results of a survey of 1200 drug users. Recommendations are made for enhancing HIV risk reduction efforts in both communities.

Abstract

Parkinson disease (PD) is the second most common neurodegenerative disorder, surpassed in frequency only by Alzheimer disease. Elsewhere we have reported linkage to chromosome 2q in a sample of sibling pairs with PD. We have now expanded our sample to include 150 families meeting our strictest diagnostic definition of verified PD. To further delineate the chromosome 2q linkage, we have performed analyses using only those pedigrees with the strongest family history of PD. Linkage analyses in this subset of 65 pedigrees generated a LOD score of 5.1, which was obtained using an autosomal dominant model of disease transmission. This result strongly suggests that variation in a gene on chromosome 2q36-37 contributes to PD susceptibility.

Abstract

The social networks of substance-using women consist of people who provide constructive social support, individuals who enable their drug use, and those who do both. Women's success in recovery may be attenuated because some of the people who are most likely to provide them with social support after drug treatment previously enabled their drug use. This article examines the social support systems of women offenders (N=100) who were mandated to four therapeutic communities in New York City. The women had an average of nine supporters (four males and five females). Although most of the women had partners who provided them with constructive social support, many of their partners also enabled their drug use. Some of the women indicated that their partners did not provide constructive support but were among their main enablers, while half of the women said that their partners actually encouraged them to stop using drugs. The majority of the women also received support from their parents, siblings, other kin, and friends. Some of these supporters also enabled their drug use while others encouraged them to stop using drugs and enter drug treatment.

Abstract

Diarrhea affects more than 60% of persons living with HIV/AIDS. Diarrhea can be caused by pathogens, neoplastic diseases, side effects of medications, malabsorption, and/or enteropathy. Activities of daily living and quality of life are often affected by HIV/AIDS-related diarrhea. Traditional Chinese medical interventions such as acupuncture and moxibustion show promise in the area of gastrointestinal symptom management. The purposes of this study were to (a) determine the influence of acupuncture and moxibustion in reducing the frequency of diarrhea and increasing stool consistency in HIV-infected men with chronic diarrhea (defined as three or more episodes of watery, liquid, or loose stools in a 24-hour period for 3 weeks or more), (b) ascertain the feasibility of the methodology for a future prospective randomized controlled trial, and (c) determine sample size estimate for a prospective randomized controlled trial. Using a time-series design, 15 HIV-positive men with chronic diarrhea received the same acupuncture/moxibustion treatment for six sessions over a 3-week period. Each participant maintained a daily stool frequency/consistency and medication diary. All treatments were administered by a licensed acupuncturist trained in traditional Chinese medicine. Based on the intent to treat analysis comparing the change in stool frequency from baseline (Week 1) to Week 3 and Week 4, stool frequency reduced approximately one episode per day (Week 3: p < .001; Week 4: p < .005). Stool consistency also improved, from baseline to Week 3 and Week 4, by more than 1 point on Hansen's stool consistency scale. Acupuncture and moxibustion are promising modalities for the symptom management of chronic diarrhea in HIV/AIDS. The results of this pilot study also establish the feasibility of a larger study and provide the empirical basis to serve as preliminary data from which to estimate statistical power and sample size for a larger efficacy study, inclusive of women as well as men.

Abstract

The purpose of this pilot study was to explore the relationships between spiritual well-being, emotional distress, HbA1c values, and blood pressure levels in a convenience sample of 22 Black women with type 2 diabetes. Results revealed significant inverse correlations between diastolic blood pressure (BP) and both total spiritual well-being (r=-.51, P=.02) and religious well-being (RWB) (r=-.55, P=.01). Women with higher RWB scores tended to have lower diastolic BP, as compared to their counterparts with lower RWB scores (z=2.78, P=.005). Emotional distress was positively related to systolic BP (r=.48, P=.03). These findings suggest that holistic care, addressing the spiritual and emotional dimensions, may foster improved BP levels among Black women with type 2 diabetes, thereby potentially reducing their high risk for secondary complications.

Abstract

Studies over the last decade have demonstrated the effectiveness of public health interventions based on social and behavioral science theory for many health problems. Little is known about the extent to which health departments are currently utilizing these theories. This study assesses the application of social and behavioral science to programs in the New York City Department of Health (NYCDOH). Structured open-ended interviews were conducted with executive and program management staff of the health department. Respondents were asked about the application of social and behavioral sciences within their programs, and about the benefits and barriers to increasing the use of such approaches. Themes related to the aims of the study were identified, a detailed coding manual developed, narrative data were coded independently by two investigators (κ .85), and data analyzed. Interviews were conducted with 61 eligible individuals (response rate 88%). The most common applications of social and behavioral science were individual-level behavior change to prevent HIV transmission and community-level interventions utilizing community organizing models and/or media interventions for health promotion and disease prevention. There are generally positive attitudes about the benefits of utilizing these sciences; however, there are also reservations about expanded use because of resource constraints. While NYCDOH has successfully applied social and behavioral sciences in some areas of practice, many areas use them minimally or not at all. Increasing use will require additional resources. Partnerships with academic institutions can bring additional social and behavioral science resources to health departments and benefit researchers understanding of the health department environment.

Abstract

The cumulative epidemiologic literature indicates that many injecting drug users (IDUs) initiate injection as a mode of drug administration during late adolescence or early adulthood. Recent studies have shown that IDUs are often exposed to viral infections relatively early in the course of injection, highlighting the importance of understanding this initiation process for both epidemiology and prevention. Epidemiologic evidence similarly suggests that at least some youth populations, most notably young men who have sex with men (YMSM), are at substantial risk for exposure to HIV and other sexually transmitted diseases (STDs) from early sexual activity. Despite the importance of this issue for both epidemiology and prevention, however, surprisingly little information is available on the social course of injection initiation, including the individual, social, or ecological factors that might mitigate or exacerbate transmission risks within the critical phase of early injection drug use. Similarly, we know little about the ways that YMSM and other high-risk youth understand risk, the kinds of exchanges and relationships in which they participate in the context of initiating sexual activity, or how drug use is operant in these exchanges and early sexual experiences. In this article, we explore key dimensions of the early initiation of injection and sexual risk, and discuss how a social network approach might be instrumental in understanding the social course of drug injection and sexual activities among youth and young adult populations.

Abstract

Individual behavior and social contexts are critical determinants of health. We surveyed commissioners or their designees in 22 departments of health serving US cities of at least 500,000 people to examine their use of scientific approaches to influence individual behavior and social contexts. Each department used behavioral or social science in its work, but only four departments were judged to have integrated these approaches throughout their operations, using both centralized and decentralized structures. Degree of integration was unrelated to collaboration with universities or communities but was related to use of explicit theories. Behavioral and social sciences were employed most frequently in the areas of HIV/AIDS and maternal and child health and in the service of changing individual behavior rather than larger contexts, although across departments many health problems and approaches were involved. Commissioners generally found the approaches valuable, but articulated barriers to more widespread adoption.

Abstract

Introduction: The purpose of this study was to explore successful relationships between foster children and foster parents. Methods: Dyads of exemplary foster parents and foster children, identified by foster care experts, were interviewed to uncover the meaning of human bonding and attachment between the foster child and foster parent. Data were collected and analyzed with use of Colazzi's phenomenologic methodology. Results A sense of family/coming home was most important for both foster children and foster parents. The powerful desire of the foster child to attain family membership emerged from their experiences, both in and out of foster care. Discussion: The combination of a caring foster parent who worked patiently with the child to help him or her establish membership and a foster child who not only recognized caring behaviors but also was willing to respond to them created the foundation for a successful relationship.
