This survey aimed to describe and compare resident and faculty physician satisfaction, attitudes, and practices regarding patients with addictions. Of 144 primary care physicians, 40% used formal screening tools; 24% asked patients' family history. Physicians were less likely (P <.05) to experience at least a moderate amount of professional satisfaction caring for patients with alcohol (32% of residents, 49% of faculty) or drug (residents 30%, faculty 31%) problems than when managing hypertension (residents 76%, faculty 79%). Interpersonal experience with addictions was common (85% of faculty, 72% of residents) but not associated with attitudes, practices, or satisfaction. Positive attitudes toward addiction treatment (adjusted odds ratio [AOR], 4.60; 95% confidence interval [95% CI], 1.59 to 13.29), confidence in assessment and intervention (AOR, 2.49; 95% CI, 1.09 to 5.69), and perceived responsibility for addressing substance problems (AOR, 5.59; CI, 2.07 to 15.12) were associated with greater satisfaction. Professional satisfaction caring for patients with substance problems is lower than that for other illnesses. Addressing physician satisfaction may improve care for patients with addictions.

This study provides population-based estimates of the incidence of constituent symptoms associated with HIV-related lipodystrophy syndrome. Possible predictors of symptomatology based on analysis of accrued cases are provided after adjustment for a broad range of personal, clinical, and treatment characteristics. Patients enrolled in a province-wide HIV/AIDS treatment program reported annually on the occurrence of lipoatrophy, lipohypertrophy, and elevated triglyceride and cholesterol levels. Of 1261 individuals who provided baseline data, 745 were available at follow-up, among whom incidence was 27% for lipoatrophy, 21% for lipohypertrophy, and 10% and 16% for increased triglyceride and cholesterol levels, respectively. In logistic multivariate modeling, incident lipoatrophy was associated with duration of stavudine (per quarter) (adjusted odds ratio [AOR] 1.18; 95% confidence interval [CI] 1.09-1.27) and having been diagnosed with AIDS (AOR 2.07; 95% CI 1.20-3.56). Lipohypertrophy risk increased with use of protease inhibitor (AOR 3.53; 95% CI 1.81-6.86) and stavudine (AOR 3.67; 95% CI 1.61-8.38). Incident cholesterol or triglyceride abnormalities were associated with protease inhibitor use (AOR 7.17; 95% CI 2.46-20.96) and duration of ritonavir (per quarter) (AOR 1.12; 95% CI 1.04-1.21). Our findings suggest high annual rates of incidence and a role of first line antiretroviral therapies in symptom development. These outcomes, in conjunction with the findings of others have important implications for evolving treatment patterns.

Access to clean needles and syringes through needle exchange programs (NEPs) has reduced both high-risk behaviors and the transmission of blood-borne infections among injection drug users (IDUs). However, policies regarding "needle-for-needle" exchange versus unrestricted needle distribution remain controversial. The objective of this study was to compare sources of needles, trends in needle distribution, and the practice of satellite needle distribution (SND) among IDUs in Vancouver and Montreal. SND was defined as receiving a new syringe from another individual through trading, purchasing, borrowing, or being given the syringe outright, or supplying a syringe to another individual through trading, selling, lending, or giving a syringe outright. This was practiced by 46% of IDUs in Vancouver and 50% of IDUs in Montreal. SND was associated with borrowing used injection equipment (adjusted OR [AOR], 2.62; 95% CI: 1.85-3.71), conducting bulk needle exchanges (AOR, 1.85; 95% CI: 1.34-2.54), being married or in a common-law relationship (AOR, 1.85; 95% CI: 1.34-2.54), and regular visits to the NEP (> weekly) (AOR, 1.54; 95% CI: 1.17-2.13). In Vancouver, SND was also associated with borrowing used needles (AOR, 2.07; 95% CI: 1.22-3.52). In these two cities, despite different distribution policies, almost half of the participants reported SND, and this was associated with high risk sharing. The practice of SND appears to be an important mechanism for needle acquisition, especially for those at highest risk for HIV and hepatitis C transmission.

Infectious disease and poor diet are the two proximal causes of malnutrition in children. During the 1990s, integrated nutrition programs implemented by Save the Children (SC) in Viet Nam reduced severe child malnutrition, but it has not been clear if this impact was due primarily to improved diet or reduced disease. The aim of this study was to determine whether a community-based, integrated nutrition program in Viet Nam reduced child morbidity due to diarrhea or acute respiratory infections. Children 5 to 25 months old were randomly selected from randomly assigned intervention and comparison communes. Caregivers of children from the intervention and comparison groups (n = 119 per group) were interviewed about their child's morbidity at program baseline and at study months 2, 4, 6, and 12. Multiple logistic regression and general estimating equations (GEE) were used to evaluate the effect of the intervention on the occurrence of any diarrhea and respiratory illness in the preceding two weeks. Respiratory illness, mainly upper respiratory illness, was more common than diarrheal disease at baseline (54% vs. 6%, respectively). During follow-up, children in the intervention communes had approximately half the respiratory illness experienced by those in comparison communes (AOR = 0.5; p = .001). Diarrheal disease was also lower in the intervention group, although differences were not statistically significant. We conclude that SC's integrated nutrition program was associated with reduced upper respiratory illness, perhaps due to improved hygiene practices and/or improved micronutrient intakes.

Recent research suggested associations between pain and subsequent all-cause and cancer-specific mortality. This study examined death and cancer development within six years of reporting pain, among women in the Royal College of General Practitioners Oral Contraception Study. We found no associations between 'any' or 'chronic' pain and subsequent all-cause mortality or cancer. We found a higher risk of death from respiratory disease among women reporting pain (adjusted odds ratio [AOR] = 2.5), a higher mortality among women reporting chronic chest pain (AOR = 1.75), and a higher risk of subsequent cancer among women reporting head or abdomen pain. Given the high prevalence of pain symptoms, these findings may be important, and warrant further research.

In sub-Saharan Africa, respiratory tract infections (RTI) are the leading cause of serious morbidity and mortality in HIV-infected persons. This study sought to investigate demographic, socioeconomic, and environmental risk factors for pneumonia in a cohort of HIV-infected women. The authors performed a nested case-control study in a cohort of HIV-1-infected adults followed in Nairobi, Kenya. Thirty-nine women who developed pneumonia during the follow-up period were selected as cases, and 66 women who did not develop pneumonia were randomly chosen to serve as control subjects. A questionnaire was administered in subjects' homes that assessed demographics, home environment, and socioeconomic status. Women were followed in the cohort for a median of 36.8 months (range, 27.3-39.3). Adjusting for length of follow-up period, factors associated with lower socioeconomic status (lower monthly spending [OR = 3.2; 95% CI, 1.2-8.4 per 10,000 Kenyan shilling decrease], having no savings [OR = 4.1; 95% CI, 1.4-11.9], less sturdy home construction material such as mud or cement walls [OR = 2.6; 95% CI, 1.1-5.9] or dirt floors [OR = 2.8; 95% CI, 1.0-7.6], and lack of a window in the home [OR = 5.5; 95% CI, 0.9-32.2]) and being widowed (OR = 4.3; 95% CI, 1.2-15.1) or single (OR = 3.3; 95% CI, 1.0-11.2) were associated with an increased risk of pneumonia. In multivariate analysis, widowed (AOR = 5.9; 95% CI, 1.3-26.3), single (AOR = 7.7; 95% CI, 1.6-36.4), and divorced (AOR = 4.5; 95% CI, 1.0-20.1) women, those without savings (AOR = 3.7; 95% CI, 1.2-11.7), and those living in more crowded and contagious conditions (AOR = 1.5; 95% CI, 1.1-2.1) remained at increased risk of pneumonia. If confirmed by prospective investigation, these findings could help identify persons and subpopulations of HIV-infected women with the greatest risk of pneumonia.

An exploratory study was conducted in the rural Estie district of Ethiopia in 1997 to identify the role of ABO blood group, rhesus factor, and type of grass pea (Lathyrus sativus) diet in the susceptibility to neurolathyrism. Five-hundred study subjects (250 cases and 250 controls) were examined and interviewed, and had their ABO and rhesus blood groups determined. The majority (86%) of the cases were males. Blood group O was the most common in the patients and controls followed by groups A, B, and AB. The vast majority of the study subjects were rhesus-positive. The gravy (Shiro) grass pea preparation was consumed by 91.6% of the study population, boiled (Nifiro) by 86%, and roasted (Kollo) by 56.4%. Almost half (48%) of the cases had consumed grass pea for > 4 months compared to 8% of controls (P < 0.001). There was a significant association between the risk for neurolathyrism and the consumption of boiled (adjusted odds ratio [AOR] = 98.4) and roasted (AOR = 55.62) forms of grass pea. There was no risk of paralysis associated with consumption of the gravy form of grass pea (AOR = 0.40, 95% confidence interval 0.1-2.0). Blood group O remained significantly associated with the disease after adjusting for age, type of grass pea preparation consumed, and duration of consumption (AOR = 2.90).

To determine whether health-care use was associated with prevalent hepatitis C virus (HCV) infection in Chennai, India, 1,947 adults from 30 slum communities were randomly selected to be interviewed about parenteral and sexual risks for HCV infection and to provide biological specimens for HCV and sexually transmitted infection (STI) testing. Prevalent HCV infection was detected in 2.4% of non-injection drug using (IDU) participants. Controlling for other associated factors, and excluding IDU, men who used informal health-care providers were five times as likely to be HCV infected as those who did not use informal providers (Adjusted Odds Ratio, AOR = 5.83; 95% confidence interval [CI]: 1.57, 21.6), a finding not detected in women. More research is needed to determine the extent to which HCV infection is associated with reuse of contaminated injection equipment in health-care settings in developing countries.

A non-magnetic mutant of Magnetospirillum magneticum AMB-1, designated as NMA21, was generated by mini-Tn5 transposon mutagenesis to identify genes involved in bacterial magnetic particle (BMP) synthesis. Alignment of the DNA sequences flanking the transposon allowed the isolation of an open reading frame (ORF2) within an operon consisting of five genes. The amino acid sequence of ORF2 showed homology with tungsten-containing aldehyde ferredoxin oxidoreductase (AOR) from Pyrococcus furiosus (48% identity and 64% similarity), which functions for aldehyde oxidation. AOR was found to be expressed under microaerobic conditions and localized in the cytoplasm of AMB-1. Iron uptake and growth of NMA21 were lower than wild type. Transmission electron microscopy (TEM) of NMA21 revealed that no BMPs were completely synthesized, but polyhydroxybutyrate (PHB)-like granules were persistently produced. These results indicate that AOR may contribute to ferric iron reduction during BMP synthesis in M. magneticum AMB-1 under microaerobic respiration.

Our aim was to examine the relative importance of family size on sensitization to two different allergens: ryegrass and house dust mite (HDM), using a mutually exclusive classification for allergen-specific sensitization. An 8-year follow-up birth cohort study of children born between 1988-89 was conducted. The follow-up sample consisted of 498 children residing in Northern Tasmania in 1997 (84% of eligible). Outcome measures included skin prick test (SPT) reaction to nine aeroallergens and parental questionnaire. Family size was defined as sibling number in 1997. Children with a positive SPT to either Der p or Der f house dust mite but not ryegrass were classified as HDM-exclusive (n = 84). Children with a positive SPT to ryegrass but not HDM were classified as ryegrass-exclusive (n = 43). Family size was associated with reduced ryegrass-exclusive sensitization [AOR 0.57 (0.39, 0.84) per increase in sibling number] but not HDM-exclusive sensitization [AOR 0.97 (0.77,1.23)]. The difference in the family size effect on these sensitization outcomes was significant (p = 0.02). Similarly, family size tended to be associated with reduced asthma among ryegrass-exclusive sensitized children [AOR 0.45 (0.18,1.12)] but not HDM-exclusive sensitized children [(AOR 1.46(0.80-2.65)]. Large family size was strongly associated with reduced sensitization for ryegrass allergens but not HDM allergens using mutually exclusive sensitization categories. If this difference is confirmed in other studies, the contrasting effect of family size may reflect differences between these allergens with regard to level or timing of early life exposure, differences in allergen -specific potentiation for sensitization or unidentified confounding. The use of mutually exclusive categories for allergen sensitization will assist future work on child atopic disease.
