Background:

Coronary atherosclerosis develops slowly over decades but is frequently characterized clinically by sudden unstable episodes. Patients who present with unstable coronary disease, such as acute myocardial infarction, may systematically differ from patients who present with relatively stable coronary disease, such as exertional angina.

Objective:

To examine whether medication use or patient characteristics influence the mode of initial clinical presentation of coronary disease.

Design:

Case-control study.

Setting:

Large integrated health care delivery system in northern California.

Patients:

Adults whose first clinical presentation of coronary disease was either acute myocardial infarction (n = 916) or stable exertional angina (n = 468).

Measurements:

Use of cardiac medications before the event from pharmacy databases and demographic, lifestyle, and clinical characteristics from self-report and clinical and administrative databases.

Results:

Compared with patients with incident stable exertional angina, patients with incident acute myocardial infarction were more likely to be men, smokers, physically inactive, and hypertensive but were less likely to have a parental history of coronary disease. Patients presenting with myocardial infarction were much less likely to have received statins (19.3% vs. 40.4%; P 0.001) and ß-blockers (19.0% vs. 47.7%; P 0.001) than patients presenting with exertional angina. After adjustment for potential confounders, recent use of statins (adjusted odds ratio, 0.45 [95% CI, 0.32 to 0.62]) and ß-blockers (adjusted odds ratio, 0.26 [CI, 0.19 to 0.35]) was associated with lower likelihoods of presenting with an acute myocardial infarction than with stable angina.

Limitations:

This observational study did not have information on all possible confounding factors, including use of aspirin therapy.

Conclusion:

Statin and ß-blocker use was associated with lower odds of presenting with an acute myocardial infarction than with stable angina. Additional studies are needed to confirm that these therapies protect against unstable, higher-risk clinical presentations of coronary disease.

Abstract: Policies aimed at reducing welfare use focus solely on adults, yet welfare users very often report experiences of childhood abuse. Such abuse is known to have long-term psychological effects and may set the stage for later welfare use. This study uses a random sample of poor women to determine how a history of childhood abuse relates to the probability of receiving cash and in-kind assistance over a five-year period. It also investigate whether childhood abuse correlates with the length of receipt among program users. Women experiencing both physical and sexual abuse during childhood were 1625 percentage points more likely than others to use both cash and in-kind programs as adults. Conditional on program use, there was no relation of childhood abuse to the extent of program use during the study period.

BACKGROUND: Gender differences in health system usage can lead to differences in the incidence of morbidity and mortality. We conducted a pilot screening targeted towards men to evaluate gender differences in cardiovascular disease risk factor detection and time since last clinic visit.

METHODS: Three evening sessions in two communities screened 148 people, mean age 47.7 years. Height, weight, body mass index, blood pressure, blood glucose, and total cholesterol were measured. A questionnaire on past medical history was administered. Participants with elevated measurements were referred to appropriate care.

RESULTS: Men accounted for 60.1% of those screened; 65.5% of the group was overweight, and 22.3% was obese with 42.6% hypertension, 39.2% hypercholesterolemia, and 2.7% high blood glucose. Among men aged 35 to 65, 65.2% were overweight, 20.3% obese, 46.4% hypertensive, 42.0% hypercholesterolemic, and 1.5% with high blood glucose. Within the last 2 years, 53.3% of men and 9.1% of women aged 35 to 65 had not visited a doctor (P = 0.004).

CONCLUSIONS: A significant portion of those screened had elevated cardiovascular disease risk factors. Given that men visited doctors significantly less frequently, efforts to involve men in prevention of cardiovascular disease within these communities are warranted.

Objective: To assess the functional and behavioral health of unaccompanied Sudanese refugee minors approximately 1 year after resettlement in the United States.

Design: A descriptive survey.

Setting: Local refugee foster care programs affiliated with the US Unaccompanied Refugee Minors Program.

Participants: A total of 304 Sudanese refugee minors enrolled in the US Unaccompanied Refugee Minors Program.

Main Outcome Measures: Health outcomes were assessed using the Harvard Trauma Questionnaire and the Child Health Questionnaire. Outcomes included the diagnosis of posttraumatic stress disorder and scores on all Child Health Questionnaire subscales and global single-item assessments.

Results: Twenty percent of the minors had a diagnosis of posttraumatic stress disorder and were more likely to have lower (worse) scores on all the Child Health Questionnaire subscales. Low functional and behavioral health scores were seen mainly in functioning in the home and in subjective health ratings. Social isolation and history of personal injury were associated with posttraumatic stress disorder.

Conclusions: Unaccompanied Sudanese minors have done well in general. The minors function well in school and in activities; however, behavioral and emotional problems manifest in their home lives and emotional states. The subset of children with traumatic symptoms had characteristics that may distinguish them from their peers and that may inform future resettlement services for unaccompanied minors in the United States.

Mortality rates in the United States fell more rapidly during the late nineteenth and early twentieth centuries than in any other period in American history. This decline coincided with an epidemiological transition and the disappearance of a mortality "penalty" associated with living in urban areas. There is little empirical evidence and much unresolved debate about what caused these improvements, however. In this article, we report the causal influence of clean water technologies -- filtration and chlorination -- on mortality in major cities during the early twentieth century. Plausibly exogenous variation in the timing and location of technology adoption was used to identify these effects, and the validity of this identifying assumption is examined in detail. We found that clean water was responsible for nearly half the total mortality reduction in major cities, three quarters of the infant mortality reduction, and nearly two thirds of the child mortality reduction. Rough calculations suggest that the social rate of return to these technologies was greater than 23 to 1, with a cost per person-year saved by clean water of about $500 in 2003 dollars. Implications for developing countries are briefly considered.

This is the first study to examine the prevalence and effects of major depression (MDD) in a sample of adolescent smokers (N = 211) undergoing treatment for nicotine dependence. We assessed MDD at baseline and end of treatment with the mood disorders portion of the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). Eleven percent of participants reported a history of MDD (6% of males and 21% of females). Study variables did not distinguish those with and without a history of MDD. End of treatment abstinence rates and relapse rates were similar in both groups. Two participants (1%), both female, experienced onset of MDD during the treatment. The findings provide further evidence that MDD is a comparatively common disorder among children and adolescents and that clinicians should monitor and be prepared to respond to depression that may emerge during the treatment of nicotine-dependent adolescents.

In 1999, the American College of Physicians (ACP), then the American College of Physicians-American Society of Internal Medicine, and the American College of Cardiology/American Heart Association (ACC/AHA) developed joint guidelines on the management of patients with chronic stable angina. The ACC/AHA then published an updated guideline in 2002, which ACP recognized as a scientifically valid review of the evidence and background paper. This ACP guideline summarizes the recommendations of the 2002 ACC/AHA updated guideline and underscores the recommendations most likely to be important to physicians seeing patients in the primary care setting. This guideline is the second of 2 that provide guidance on the management of patients with chronic stable angina. This document covers treatment and follow-up of symptomatic patients who have not had an acute myocardial infarction or revascularization procedure in the previous 6 months. Sections addressing asymptomatic patients are also included. Asymptomatic refers to patients with known or suspected coronary disease based on a history or electrocardiographic evidence of previous myocardial infarction, coronary angiography, or abnormal results on noninvasive tests. A previous guideline covered diagnosis and risk stratification for symptomatic patients who have not had an acute myocardial infarction or revascularization procedure in the previous 6 months and asymptomatic patients with known or suspected coronary disease based on a history or electrocardiographic evidence of previous myocardial infarction, coronary angiography, or abnormal results on noninvasive tests.
