Too far, too little, too late: a community-based case-control study of maternal mortality in rural west Maharashtra, India.
(65/18160)
A total of 121 maternal deaths, identified through multiple-source surveillance in 400 villages in Maharashtra, were prospectively enrolled during 1993-95 in a population-based case-control study, which compared deaths with the survivors of similar pregnancy complications. The cases took significantly longer to seek care and to make the first health contact after the decision to seek care was taken. They also travelled significantly greater distances through a greater number of health facilities before appropriate treatment was started. Multivariate analysis showed the negative effect of excessive referrals and the protective effect of the following: residing in and not away from the village; presence of a resident nurse in the village; having an educated husband and a trained attendant at delivery; and being at the woman's parents' home at the time of illness. Other significant findings showed that deaths due to domestic violence were the second-largest cause of deaths in pregnancy, that more than two-thirds of maternal deaths were underreported in official records, and that liveborn infants of maternal deaths had a markedly higher risk of dying in the first year of life. This study points to the need for information-education-communication (IEC) efforts to increase family (especially male) preparedness for emergencies, decentralized obstetric management with effective triage, and a restructuring of the referral system.

The effect of a Medicaid managed care program on the adequacy of prenatal care utilization in Rhode Island.
(66/18160)
OBJECTIVES: The purpose of this study was to determine whether adequacy of prenatal care utilization improved after the implementation of a Medicaid managed care program in Rhode Island. METHODS: Rhode Island birth certificate data (1993-1995; n = 37021) were used to analyze pre- and post-program implementation changes in adequacy of prenatal care utilization. Logistic regression models were used to characterize the variation in prenatal care adequacy as a function of both time and the various covariates. RESULTS: Adequacy of prenatal care utilization for Medicaid patients improved significantly after implementation of the program, from 57.1% to 62.1% (odds ratio [OR] = 1.2, 95% confidence interval [CI] = 1.1, 1.3). After the program was implemented, Medicaid patients who went to private physicians' offices for prenatal care were 1.4 times as likely as before to receive adequate prenatal care (OR = 1.4, 95% CI = 1.2, 1.7). CONCLUSIONS: Unlike many other Medicaid expansions for pregnant women, the RIte Care program in Rhode Island has resulted in significant improvement in adequacy of prenatal care utilization for its enrollees. This improvement was due to specific program interventions that addressed and changed organizational and delivery system barriers to care. (+info)
Maternal intrapartum temperature elevation as a risk factor for cesarean delivery and assisted vaginal delivery.
(67/18160)
OBJECTIVES: This study investigated the association of intrapartum temperature elevation with cesarean delivery and assisted vaginal delivery. METHODS: Participants were 1233 nulliparous women with singleton, term pregnancies in vertex presentations who had spontaneous labors and were afebrile (temperature: 99.5 degrees F [37.5 degrees C]) at admission for delivery. Rates of cesarean and assisted vaginal deliveries according to highest intrapartum temperature were examined by epidural status. RESULTS: Women with maximum intrapartum temperatures higher than 99.5 degrees F were 3 times as likely to experience cesarean (25.2% vs 7.2%) or assisted vaginal delivery (25.2% vs 8.5%). The association was present in epidural users and nonusers and persisted after birthweight, epidural use, and labor length had been controlled. In adjusted analyses, temperature elevation was associated with a doubling in the risk of cesarean delivery (odds ratio [OR] = 2.3, 95% confidence interval [CI] = 1.5, 3.4) and assisted vaginal delivery (OR = 2.1, 95% CI = 1.4, 3.1). CONCLUSIONS: Modest temperature elevation developing during labor was associated with higher rates of cesarean and assisted vaginal deliveries. More frequent temperature elevation among women with epidural analgesia may explain in part the higher rates of cesarean and assisted vaginal deliveries observed with epidural use. (+info)
Factors associated with refusal to treat HIV-infected patients: the results of a national survey of dentists in Canada.
(68/18160)
OBJECTIVES: This study investigated dentists refusal to treat patients who have HIV. METHODS: A survey was mailed to a random sample of all licensed dentists in Canada, with 3 follow-up attempts (n = 6444). Data were weighted to allow for probability of selection and nonresponse and analyzed with Pearson's chi 2 and multiple logistic regression. RESULTS: The response rate was 66%. Of the respondents, 32% had knowingly treated HIV-infected patients in the last year; 16% would refuse to treat HIV-infected patients. Respondents reported willingness to treat HIV-infected patients (81%), injection drug users (86%), hepatitis B virus-infected patients (87%), homosexual and bisexual persons (94%), individuals with sexually transmitted disease(s) (94%), and recipients of blood and blood products (97%). The best predictors of refusal to treat patients with HIV were lack of ethical responsibility (odds ratio = 9.0) and items related to fear of cross-infection or lack of knowledge of HIV. CONCLUSIONS: One in 6 dentists reported refusal to treat HIV-infected patients, which was associated primarily with respondents' lack of belief in an ethical responsibility to treat patients with HIV and fears related to cross-infection. These results have implications for undergraduate, postgraduate, and continuing education. (+info)
Maternal placental abnormality and the risk of sudden infant death syndrome.
(69/18160)
To determine whether placental abnormality (placental abruption or placental previa) during pregnancy predisposes an infant to a high risk of sudden infant death syndrome (SIDS), the authors conducted a population-based case-control study using 1989-1991 California linked birth and death certificate data. They identified 2,107 SIDS cases, 96% of whom were diagnosed through autopsy. Ten controls were randomly selected for each case from the same linked birth-death certificate data, matched to the case on year of birth. About 1.4% of mothers of cases and 0.7% of mothers of controls had either placental abruption or placenta previa during the index pregnancy. After adjustment for potential confounders, placental abnormality during pregnancy was associated with a twofold increase in the risk of SIDS in offspring (odds ratio = 2.1, 95% confidence interval 1.3-3.1). The individual effects of placental abruption and placenta previa on the risk of SIDS did not differ significantly. An impaired fetal development due to placental abnormality may predispose an infant to a high risk of SIDS. (+info)
Smoking and the occurrence of Alzheimer's disease: cross-sectional and longitudinal data in a population-based study.
(70/18160)
The authors tested the hypothesis that smoking exerts a protective effect on Alzheimer's disease or dementia in a population-based cohort of 668 people aged 75-101 years (Sweden). Smoking was negatively associated with prevalent Alzheimer's disease (adjusted odds ratio = 0.6, 95% confidence interval 0.4-1.1) and dementia (adjusted odds ratio = 0.6, 95% confidence interval 0.4-1.0). Over 3-year follow-up (1989-1992), the hazard ratios of incident Alzheimer's disease and dementia due to smoking were 1.1 (95% confidence interval 0.5-2.4) and 1.4 (95% confidence interval 0.8-2.7). Mortality over 5-year follow-up was greater among smokers in demented (hazard ratio = 3.4) than nondemented (hazard ratio = 0.8) subjects. Smoking does not seem protective against Alzheimer's disease or dementia, and the cross-sectional association might be due to differential mortality. (+info)
Artemether for severe malaria: a meta-analysis of randomized clinical trials.
(71/18160)
The treatment of choice for severe malaria is quinine. However, a gradual progression of resistance to quinine has become a concern in parts of the world. Artemisinin-related compounds are a relatively new class of drugs. This meta-analysis assesses the evidence regarding the clinical effectiveness of artemether for severe malaria. Computerized literature searches identified all randomized clinical trials of artemether in comparison with quinine. Standardized data extraction was independently performed by both authors. Results of nine trials, entered in the meta-analysis, demonstrate the absence of a significant difference between artemether and quinine in terms of mortality rate (odds ratio [OR], 0.76; 95% confidence interval [CI], 0.50-1.14). Statistical pooling of data from trials in Southeast Asia showed a trend toward enhanced reduction of mortality (OR, 0.38; 95% CI, 0.14-1.02). These data demonstrate the equality of artemether and quinine for severe malaria and indicate a trend toward greater effectiveness of artemether in regions where there is recognized quinine resistance.

Socioeconomic status and cardiovascular risk factors in the Czech Republic.
(72/18160)
BACKGROUND: In western countries, prevalence of cardiovascular diseases and most risk factors is higher in lower socioeconomic groups. The social gradients in the former communist societies are less well known. Because in western countries different indicators of socioeconomic status (SES) are correlated, this gradient is found with a number of different measures of SES. We have analysed the presence and magnitude of the socioeconomic gradient in cardiovascular risk factors in a former communist country. As the relationship between material conditions and education has been much weaker than in the west, we have also attempted to separate their effects. METHODS: A cross-sectional survey examined a random sample of men and women resident in six Czech districts participating in the MONICA study in 1992. Participants completed a questionnaire, underwent anthropometric and blood pressure measurements, and provided a blood sample. Two indicators of SES were used: education and material conditions, the indicator constructed from car ownership and crowding. Linear regression was employed to analyse the relation between SES and total and high-density lipoprotein (HDL) cholesterol, body mass index (BMI), waist-hip ratio (WHR) and height. Logistic regression was used to assess the association between SES and smoking and hypertension. RESULTS: A total of 1141 men and 1212 women (overall response rate 75%) participated in the study. After controlling for age, all risk factors were associated with education, except HDL cholesterol in women and BMI in men; only smoking in both sexes and WHR in women and height in men were significantly related to material conditions. In mutually adjusted analyses, educational gradients persisted but associations with material conditions disappeared or became substantially weaker. The magnitude of the educational differences was similar to those found in western countries. CONCLUSIONS: Socioeconomic differences in cardiovascular risk factors in Czech Republic in 1992 had the same direction and similar magnitude as in Western Europe, and were strongly related to education rather than material conditions. Materialist explanations for the social differences seem unlikely in this population. (+info)
