Phenylephrine induces relaxation of longitudinal strips from small arteries of goat legs.

Alpha adrenergic stimulation is known to produce vasoconstriction. We have earlier shown that, in spiral strips of small arteries Phenylephrine (PE) caused vasorelaxation under high nitric oxide (NO) environment. However, on further experimentation it was realized that the PE-induced vasorelaxant response occurred only with longitudinal strips of small arteries even under normal NO environment while circular strips showed contraction with PE even under high NO environment.

Trends and responsiveness in national resource allocation for needed HIV services: a five year (1996-2000) analysis.

A recent study conducted by the Institute of Medicine concluded that there are approximately 1,200 to 1,400 avoidable deaths per year in the U.S. among people living with HIV (PLWH) who do not have health insurance (Institute of Medicine, 2002).

Mental health status of clients from three HIV/AIDS palliative care projects.

Objective: To describe mental health status and its correlates among clients of three palliative care programs targeting underserved populations.

Methods: Mental Health Inventory (MHI-5) scores of clients from programs in Alabama (n = 39), Baltimore (n = 57), and New York City (n = 84) were compared.

Results: Mean MHI-5 scores did not differ among sites and were indicative of poor mental health.

Patient reports of symptoms and their treatment at three palliative care projects servicing individuals with HIV/AIDS.

Self-reports of 32 symptoms and their treatments were obtained from patients of three palliative care programs that provide services to seriously ill HIV patients (>or=95% AIDS) in Alabama (n=47), Baltimore (n=91), and New York City (n=117). On average, patients reported 10.9 (SD=7.

Access and equity in HIV/AIDS palliative care: a review of the evidence and responses.

The high prevalence of pain and other symptoms throughout the HIV disease trajectory, the need for management of side effects related to antiretroviral therapy, the continuing incidence of cancers and new emerging co-morbidities as a result of extended life expectancy under new therapeutic regimes, and the ongoing need for terminal care all prove the curative versus palliative dichotomy to be inappropriate. Although there is evidence for both need and effectiveness of palliative care in HIV patient care, access is often poor and care less than optimal. This review aimed to identify evidence of barriers and inequalities in HIV palliative care in order to inform policy and service development.

Does palliative care improve outcomes for patients with HIV/AIDS? A systematic review of the evidence.

Background: The need for palliative care in HIV management is underlined by the high prevalence of pain and symptoms, the toxicity, side effects, and virological failure associated with antiretroviral therapy, emergence of co-morbidities, continued high incidence of malignancies, late presentation of people with HIV disease, and the comparatively higher death rates among the infected individuals.

Methods: A systematic review was undertaken to appraise the effect of models of palliative care on patient outcomes. A detailed search strategy was devised and biomedical databases searched using specific terms relevant to models of palliative care.

Health and support service utilization patterns of American Indians and Alaska Natives diagnosed with HIV/AIDS.

The purpose of this analysis is twofold: to examine the types of health and support services provided by CARE Act funded providers to American Indians/Alaska Natives and to compare the characteristics and service utilization patterns for this group with those of individuals from other racial/ethnic groups. We present an analysis of the demographic characteristics, service utilization, and health outcomes of all HIV-infected clients who received services in five geographic areas at agencies that were funded through the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act. Standard chi-square tests were used to test for statistically significant differences (p <.

Service needs of patients with advanced HIV disease: a comparison of client and staff reports at three palliative care projects.

Despite prolonged survival and improved quality of life as a result of treatment advances for HIV/AIDS, thousands still suffer with the disease and 15-16,000 a year die in the United States alone. Little is known about those patients with HIV/AIDS who still require palliative care services or the types of services needed. This paper describes the program elements and clients of three programs providing palliative care to persons with HIV/AIDS in Alabama (n = 41), Baltimore, Maryland, (n = 55), and New York City (n = 52).

Current HIV/AIDS end-of-life care in sub-Saharan Africa: a survey of models, services, challenges and priorities.

Background: In response to increased global public health funding initiatives to HIV/AIDS care in Africa, this study aimed to describe practice models, strategies and challenges to delivering end-of-life care in sub-Saharan Africa.

Methods: A survey end-of-life care programs was conducted, addressing the domains of service aims and configuration, barriers to pain control, governmental endorsement and strategies, funding, monitoring and evaluation, and research. Both closed and qualitative responses were sought.

Evaluation of pediatric HIV care provided in Ryan White CARE Act Title IV Women, Infants, Children, and Youth Clinics.

This evaluation examines the changing practices and outcomes of pediatric HIV care provided by the Ryan White Comprehensive AIDS Resources and Emergency (CARE) Act, Title IV grantees from 1996 through 1998--a period of rapidly changing medical practice within the United States. Using medical chart abstraction, 26 Title IV grantees reported information from the records of 525 HIV positive clients between the ages of 2 and 12. The chart abstractions covered medical care and case management provided to these clients including the number of clinical visits, use of antiretroviral therapy, use of laboratory tests such as CD4+ cell count (cells/mm3) and HIV-1 RNA viral load (copies/mL), enrollment in clinical trials, and receipt of opportunistic infection prophylaxis.

Delivering HIV services to vulnerable populations: an evaluation and research agenda.

In May 2000, the HIV/AIDS Bureau of the Health Resources and Services Administration convened HIV experts from throughout the country to identify new and emerging areas of research needed to guide policy and programmatic decisions on HIV service delivery to vulnerable populations. This article describes the process used to develop an evaluation/research agenda, discusses key findings and recommendations of the conference, and proposes a set of principles to guide the design and conduct of future investigations. Conference participants identified nine major evaluation/research themes that span the continuum of HIV behavioral prevention services and treatment.

Delivering HIV services to vulnerable populations: a review of CARE Act-funded research.

This article summarizes key findings from evaluation and research studies that have received financial support from the HIV/AIDS Bureau of the Health Resources and Services Administration or from Ryan White Comprehensive AIDS Resources Emergency (CARE) Act grantees. These studies suggest that the CARE Act has improved but not equalized service accessibility, quality, and outcomes for different populations living with HIV disease. Evaluations of access to highly active antiretroviral therapy (HAART) found that uninsured patients, women, people of color, and injection drug users waited much longer than others to receive the new therapies.

Factors associated with delays in accessing HIV primary care in rural Arkansas.

While debate continues at what stage of human immunodeficiency virus (HIV) disease to begin combination antiretroviral therapy, a number of clinical and public health benefits are linked to early entry into primary care soon after first testing HIV positive. However, HIV-infected patients continue to test late and delay entry into care. We used routinely collected demographic and clinical information to examine which factors are associated with delays in seeking care in a predominantly rural, economically poor area of Arkansas.

Satisfaction with innovative community and university health clinic programs for groups of traditionally underserved individuals with HIV/AIDS: empirical models.

As the demographics of the populations of affected individuals have changed, systems of care have needed to adapt to be responsive to client needs. This article examines client satisfaction data from seven national demonstration projects funded to enroll individuals from traditionally underserved groups and help them access services using different strategies. Data on client satisfaction ratings were related to indicators of traditionally underserved status, including demographic characteristics, behaviors, and other risk factors using the data modeling method of Exhaustive CHAID (Chi-squared Automatic Interaction Detector).

Finding the underserved: directions for HIV care in the future.

The demographic, behavior, and background characteristics of 4,804 participants in 17 national demonstration projects for HIV medical and/or psychosocial support services were coded for an index of "service need" or possible under-representation in the traditional healthcare system. Fifteen items were coded including status as a person of color, lack of private insurance, unemployment/disability, problem drinking, crack cocaine use, heroin use, other illicit drug use, less than 12 years of education, criminal justice system involvement, children requiring care while the patient receives services, sex work, being the sex partner of an injection drug user, unstable housing, primary language not English, and age less than 21 or over 55 years. Most (87.

Perceived barriers to receiving HIV services in groups of traditionally underserved individuals: empirical models.

Persons living with HIV/AIDS face many issues that make them highly vulnerable to a number of health and social problems. As the demographics of the epidemic have shifted in recent years, many members of traditionally underserved groups have encountered barriers to entering the services system. This article uses data from seven national demonstration projects funded to enroll persons with HIV/AIDS who tend to "fall through the cracks" and help them access needed services.

Satisfaction with services in innovative managed care programs for groups of traditionally underserved individuals with HIV/AIDS: empirical models.

As the number of people with HIV/AIDS receiving services in managed care models increases, concerns over quality of care and satisfaction with services have grown. This article examined data from three national demonstration projects that were funded to enroll traditionally underserved individuals and provide innovative medical services in programs developing models appropriate for managed care funding. Assessments of patient satisfaction were related to indicators of traditionally underserved status including demographic characteristics, behaviors, and other risk factors using the data modeling method of Exhaustive CHAID (Chi-squared Automatic Interaction Detector).

Service needs and factors related to quality of life at time of service enrollment among persons living with HIV.

This article explores the relationships of HIV risk factors, service needs, and vulnerabilities to health-related quality of life in a sample of 1,371 participants newly enrolled into 13 innovative HIV/AIDS treatment model service demonstration projects. These projects targeted services to traditionally underserved populations. Eight distinct quality of life clusters of HIV patients were used in this analysis along with patient self-identified risk factors.

Typology of quality of life experiences among persons living with HIV.

This article develops a typology of 2,038 participants in 13 innovative HIV/AIDS treatment model service demonstration projects targeted to traditionally underserved populations. The typology is based on self-reported health-related quality of life levels. Eight clusters were identified that classify HIV/AIDS patients based on their reported health-related quality of life.

Who receives Ryan White CARE Act services? A demographic comparison of CARE act clients and the general AIDS population.

This study examines the extent to which health and social service providers funded by the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act serve women, minorities, and other vulnerable populations emphasized by the legislation. Demographic characteristics of AIDS-diagnosed clients served by CARE Act-funded providers in four metropolitan areas and two states are compared with Centers for Disease Control and Prevention estimates of AIDS prevalence. Clients of CARE Act-funded providers tend to reflect the demographics of local HIV/AIDS epidemics.
