Importance of community size in practice location decisions of final year residents

Final year residents in training in Louisiana were surveyed regarding plans for medical practice and their perceptions of the importance of various factors in choosing practice locations. Most specialty groups selected smaller communities at similar rates. Growing up in small towns is associated with wanting to practice in small towns while concerns about opportunities for the family and income of the region are associated with wanting to practice in a larger city.This study was supported by the Louisiana Council for Statewide Planning for Physician Manpower through Contract No. 23058, Louisiana Department of Health and Human Resources.Ms. Samaha is a data analyst for the Louisiana Council for Statewide Planning for Physician Manpower; Robert R.

Apoptosis: understanding the new molecular pathway.

Advances in science have increased the knowledge of how cells die in the body (apoptosis). A basic understanding of this process can improve nurses' ability to review new scientific literature and enable them to provide safer bedside care.     

Levels of Psychological Distress Experienced by Family Carers of Children and Adolescents with Intellectual Disabilities in an Urban Conurbation

Background The aim of the present study was to identify factors associated with the level of psychological distress reported by family carers of children with intellectual disability living in a large urban conurbation. Method Information was collected by postal questionnaire (or interview for family carers who did not have English as their first language) from the family carers of 408 children with intellectual disability (31% of all children within the area administratively identified as having an intellectual disability). Results Results indicated that 47% of primary carers scored above the threshold for psychological distress on the GHQ and that scoring above the threshold was strongly related to the emotional and behavioural needs of the index child and South‐Asian ethnicity and moderately associated with the severity of the child's delay in communication. Conclusions The rates of psychological distress (47% overall, 70% among South‐Asian carers) were markedly higher than that found in previous studies of carers supporting a child with intellectual disabilities. It is suggested that these elevated rates of psychological distress may be mediated by socio‐economic deprivation.     

Determinants of health-service use by low-income people.

Poverty influences health status, life expectancy, health behaviours, and use of health services. This study examined factors influencing the use of health-related services by people living in poverty. In the first phase, 199 impoverished users of health-related services in 2 large Canadian cities were interviewed by their peers. In the second phase, group interviews with people living in poverty (n = 52) were conducted. Data were analyzed using thematic content analysis. Diverse health-related services were used to meet basic and health needs, to maintain human contact, and to cope with life's challenges. Use of services depended on proximity, affordability, convenience, information, and providers' attitudes and behaviours. Use was impeded by inequities based on income status. To promote the health of people living in poverty, nurses and other health professionals can enhance the accessibility and quality of services, improve their interactions with people living in poverty, provide information about available programs, offer coordinated community-based services, collaborate with other sectors, and advocate for more equitable services and policies.     

Influenza A pneumonia presenting as progressive focal infiltrates in a stem cell transplant recipient.

BACKGROUND: Stem cell transplant recipients are susceptible to pulmonary infections, including influenza A. Typically, isolated influenza pneumonia has a diffuse, interstitial infiltrate pattern. OBJECTIVES: To describe the unusual clinical and radiographic course of influenza A pneumonia in a stem cell transplant recipient. STUDY DESIGN: Case report in which microbiologic assays, bronchoscopic and pathologic specimens are obtained. RESULTS: We describe a patient with influenza A pneumonia 8 months following a peripheral blood stem cell transplant who presented with minimal respiratory symptoms and rapidly progressing, focal pulmonary infiltrates. The large size and appearance of the masses have not been reported before in a patient with isolated influenza. CONCLUSION: This case highlights the differences of presentation and importance of early diagnosis and treatment of immunocompromised patients infected with influenza.     

Safety of GM-CSF in Patients with AIDS: A Review of the Literature

We performed a literature search for all clinical studies reporting outcomes in patients with the acquired immunodeficiency syndrome (AIDS) receiving granulocyte-macrophage colony-stimulating factor (GM-CSF) for any indication. Safety outcomes included human immunodeficiency virus replication, immune status, and frequency of opportunistic infections and neoplasms. Data were synthesized qualitatively. We identified 22 studies (274 patients): 12 addressed AIDS neutropenia, 8 AIDS cancer therapy, and 2 opportunistic infections. Viral burden was assessed by serum p24Ag in 15 studies. Nine reported no change in levels, three net decreases, and three net increases. All studies showing net increases involved patients receiving GM-CSF without a concurrent antiretroviral. The CD4 counts were unchanged in 5 studies, increased in 3, and not reported in 14. The incidence of neoplasms or new opportunistic infections was low. The literature suggests no increased risk of viral replication or clinical deterioration in patients with AIDS who take GM-CSF concurrently with zidovudine.     

Ethanol Feeding Causes Inactivation of Both State 1 and State 2 Rat Hepatic Asialoglycoprotein Receptors

Previous studies have shown that ethanol feeding in rats causes inactivation and redistribution of ˜50% of the total asialoglycoprotein receptors (ASGPRs) in hepatocytes (Tworek et al., J. Biol. Chem. 271:2531, 1996), and that two equal populations of hepatic ASGPRs mediate ligand uptake and processing via two functionally different pathways (Weigel in Glycoconjugates: Composition, Structure and Function , Marcel Dekker, 1992, p. 421). The purpose of this study was to determine if ethanol feeding causes preferential inactivation of only one of these two ASGPR populations, which have been designated state 1 and state 2 ASGPRs. The state 2, but not state 1, ASGPRs are inactivated in isolated hepatocytes by a variety of drugs and inhibitors. State 2 ASGPRs can also be inactivated in permeable cells by ATP treatment and then reactivated by treatment with fatty acyl coenzyme As. In the present study, permeable cell assays for state 2 ASGPR inactivation and reactivation were used to assess whether hepatocytes from ethanol-fed rats contain inactive state 2 ASGPRs. The results show that preferential inactivation of one ASGPR population does not occur after ethanol feeding. That inactive ASGPRs could not be reactivated by treatment with palmitoyl-coenzyme A to a greater extent in ethanol-fed versus control cells indicates there is not a larger pool of inactivated state 2 ASGPRs in treated cells. We conclude that ethanol feeding causes equal inactivation of both state 1 and state 2 ASGPRs. Ethanol feeding may represent the first treatment found to inactivate state 1 ASGPRs.
