This article debunks myths about pharmaceuticals and, more specifically, to defend the drug manufacturers from unfair attacks against their products in the media. Merck, a company which has been accused of draconian indifference to cardiac risks, should in fact be applauded for its new vaccine against Human Papillomavirus called Gardasil. The FDA has approved Gardasil, and when it is used regularly in daily medical practice, several thousand less women per year should get gynecological cancer

We utilized coronary artery calcium scores (CACS) to assess differences in atherosclerosis burden between asymptomatic White populations living in continents with different cardiovascular disease rates. The similarities in the genetic pool between Brazilian and Portuguese Caucasian subjects offered an opportunity to assess the influence of environmental factors on the development of atherosclerosis. We reviewed CACS data from 17,563 individuals (12,378 men and 5169 women) collected in the USA (74% of the subjects), Brazil (15% of the subjects) and Portugal (11% of the subjects). CACS was absent in 80 and 88% of Portuguese men and women, compared with 46 and 62% and 33 and 59% of Brazilian and US counterparts (p<0.0001). Although the US subjects showed the lowest prevalence of risk factors they had a higher median (interquartile range) CACS than the Brazilian and the Portuguese cohorts: 4 (0;87), 1 (0;68) and 0 (0;0), respectively (p<0.0001). After adjusting for differences in age and cardiovascular risk factors, US men showed higher relative risk ratios of having any CACS than either Brazilian or Portuguese men. Brazilian and US women did not differ as far as risk of CACS although they demonstrated a greater risk than Portuguese women. In this study, significant differences in CACS were detected among three nations in different continents. The CACS differences paralleled the respective cardiovascular mortality rates.

BACKGROUND: The standard measure of efficacy used in migraine trials is a 4-point patient-rated headache pain intensity (HPI) scale. However, it has been suggested that using a stopwatch to measure the time to meaningful pain relief can provide a more precise measurement of treatment response. OBJECTIVE: This study evaluated the sensitivity of a stopwatch method for detecting meaningful relief of headache pain and the correlation of this method with the HPI scale and a 5-point pain relief scale. METHODS: In this open-label, parallel-group pilot study, patients were randomized to receive oral eletriptan 40 mg, eletriptan 80 mg, or rizatriptan 10 mg for the treatment of a single acute migraine attack. The effect of study treatment on migraine pain was assessed immediately before dosing and at 0.5, 1, 1.5, 2, 3, and 4 hours after dosing. At each time point, patients recorded the 3 types of pain assessment in a patient diary. HPI was rated using the standard 4-point International Headache Society pain intensity scale (from 0 = no pain to 3 = severe pain). Pain relief was rated on a 5-point pain relief scale (from 4 = no relief to 0 = complete relief). The time to the onset of meaningful pain relief was measured using a stopwatch. At 4 hours after dosing, patients provided a global rating of the overall efficacy of study medication on a 5-point scale (from 0 = poor to 4 = excellent). RESULTS: Seventy-nine patients participated in the trial (78.5% female; mean [SD] age, 37.7 [9.8] years; 58.2% white). The median times to meaningful pain relief measured by stopwatch were 84, 72, and 93 minutes for eletriptan 40 mg, eletriptan 80 mg, and rizatriptan 10 mg, respectively (log-rank P = 0.029, eletriptan 80 mg vs rizatriptan 10 mg). At 90 minutes (approximating the median time to meaningful pain relief on the stopwatch), headache response rates using HPI scoring (mild to no pain) were 65%, 68%, and 52% in the respective treatment groups, with no significant difference between groups. On the pain relief scale, the corresponding mean (SD) scores at 90 minutes were 1.6 (1.2), 1.4 (1.3), and 2.0 (1.4) (P = NS). The pain relief-defined response (> or = 75% pain relief) at 90 minutes did not differ significantly between the 3 treatment groups (62%, 56%, and 48%). Detection of early improvement (0.5 and 1 hour) was similar with the HPI and pain relief scales. CONCLUSION: The results of this open-label pilot study suggest the convergent validity of 3 pain-assessment methods in migraine, but indicate that the use of a stopwatch may be a more sensitive method for detecting between-group differences

BACKGROUND: Male veterans represent a large population at risk for acquiring or transmitting human immunodeficiency virus (HIV) infection. We sought to determine the prevalence of risky sexual behavior among veterans with and without HIV infection and to assess the relationship of intoxication before intercourse and other measures of drug and alcohol use to risky sexual behavior in this population. METHODS: We analyzed baseline data on 1009 HIV-positive (mean age 49 years) and 710 HIV-negative male veterans (mean age 55 years) who were participating in the Veterans Aging Cohort 5-Site Study (VACS 5). Participants completed a written questionnaire that included measures of alcohol and drug use and risky sexual behavior. RESULTS: Compared with HIV-negative veterans, HIV-positive veterans were more likely to report 5 or more sexual partners in the past year (14% vs. 4%, P < 0.01), less likely to report not using a condom at last intercourse (25% vs. 75%, P < 0.01), and similarly likely to report having 2 or more partners and inconsistent condom use (10% vs. 10%). Among sexually active HIV-positive veterans, intoxication before intercourse was significantly associated with having 5 or more sexual partners in the past year (odds ratio [OR] 1.8, 95% confidence interval [CI] 1.1-2.8), inconsistent condom use (OR 1.8, 95% CI 1.2-2.7), and the combined measure of 2 or more partners and inconsistent condom use (OR 1.8, 95% CI 1.1-3.0). Intoxication before intercourse was not significantly associated with these behaviors in HIV-negative veterans, although similar trends were noted. CONCLUSION: Risky sexual behavior was common among male veterans attending outpatient clinics and is more common among HIV-positive veterans who use alcohol and drugs in sexual situations. Asking HIV-positive men a single question about intoxication before intercourse could help to identify men at increased risk of engaging in risky sexual behavior, and specific advice to avoid intoxication in sexual situations could help to reduce risky sexual behavior

BACKGROUND: The Veterans Aging Cohort Study (VACS) is a study of human immunodeficiency virus (HIV) infected and uninfected patients seen in infectious disease and general medical clinics. VACS includes the earlier 3 and 5 site studies (VACS 3 and VACS 5) as well as the ongoing 8 site study. OBJECTIVES: We sought to provide background and context for analyses based upon VACS data, including study design and rationale as well as its basic protocol and the baseline characteristics of the enrolled sample. RESEARCH DESIGN: We undertook a prospectively consented multisite observational study of veterans in care with and without HIV infection. MEASURES: Data were derived from patient and provider self report, telephone interviews, blood and DNA samples, focus groups, and full access to the national VA 'paperless' electronic medical record system. RESULTS: More than 7200 veterans have been enrolled in at least one of the studies. The 8 site study (VACS) has enrolled 2979 HIV-infected and 3019 HIV-uninfected age-race-site matched comparators and has achieved stratified enrollment targets for race/ethnicity and age and 99% of its total target enrollment as of October 30, 2005. Participants in VACS are similar to other veterans receiving care within the VA. VACS participants are older and more predominantly black than those reported by the Centers for Disease Control. CONCLUSIONS: VACS has assembled a rich, in-depth, and representative sample of veterans in care with and without HIV infection to conduct longitudinal analyses of questions concerning the association between alcohol use and related comorbid and AIDS-defining conditions

BACKGROUND: Alcohol use is a frequent root cause of homelessness, and both homelessness and alcohol use influence the quality and quantity of interactions with health care providers. OBJECTIVE: The objectives of this study are to compare rates of homelessness and alcohol use in a cohort of human immunodeficiency virus (HIV)-infected persons and to evaluate the influence of homelessness and alcohol use on utilization of health services. RESEARCH DESIGN AND MEASURES: Data were obtained from the Veterans Aging Cohort 3-Site Study, a cohort study of 881 HIV-infected veterans at 3 VA hospitals. In a baseline survey, we assessed current and past history of homelessness and levels of alcohol consumption. Health care service utilization (ambulatory visits, emergency room visits, and hospital admissions) for the preceding 6 months was determined by self-report and VA administrative records. Logistic regression was used to assess whether homelessness and drinking variables were associated with health care visits in the past 6 months. RESULTS: Among HIV-infected veterans with complete data (n = 839), 62 (7%) were currently homeless, and 212 (25.3%) had a past, but not current, history of homelessness. Among the currently homeless, 36% reported alcohol consumption, 34% were hazardous drinkers, 46% were binge drinkers, and 26% had a diagnosis of alcohol abuse. When adjusting for age, severity of HIV disease, and use of illicit drugs, hazardous drinking (adjusted odds ratio [AOR] 0.68, 95% confidence interval [CI] 0.49-0.93) and current homelessness (AOR 0.56, 95% CI 0.32-0.97) were associated with less than 2 outpatient clinic visits. HIV-infected veterans who were homeless in the past were more likely to be hospitalized in the prior 6 months than those never homeless (AOR 1.51, 95% CI 1.07-2.11). CONCLUSIONS: Although homeless HIV-infected veterans tend to use inpatient services more than nonhomeless HIV infected veterans, they were less likely to achieve optimum outpatient care. Alcohol use complicates the effect of homelessness on adherence to outpatient care and is associated with increased inpatient utilization among HIV-infected veterans

BACKGROUND: Although alcohol problems are common in human immunodeficiency virus (HIV)-infected patients, their impact on health care services use in HIV-infected patients is not well understood. OBJECTIVE: We sought to examine the association between alcohol problems and health care services use in HIV-infected and HIV-uninfected patients. DESIGN, SETTING, AND SUBJECTS: We undertook a prospective analysis of 16,048 HIV-infected veterans and 32,096 age-, race-, gender-, and region-matched HIV-uninfected controls identified through the national Veterans Affairs electronic administrative medical record database. We identified subjects with alcohol problems using ICD-9-CM codes for alcohol diagnoses and/or alcohol-related complications. MAIN OUTCOME MEASURES: We measured outpatient visits, emergency department visits, and inpatient hospitalizations over 12 months of follow-up. RESULTS: In adjusted analyses, HIV-infected veterans with alcohol problems were significantly more likely than HIV-uninfected veterans without alcohol problems to have at least 1 outpatient visit and at least 1 inpatient hospitalization and, among those with any health services use, to have significantly greater rates for outpatient visits (Incidence rate ratio [IRR] 2.17; 95% confidence interval [CI] 2.06-2.28; P < 0.001), emergency department visits (IRR 1.46; 95% CI 1.35-1.58; P < 0.001), and inpatient hospitalizations (IRR 1.46; 95% CI 1.30-1.64; P < 0.001). The incidence rates for outpatient visits, mental health visits, emergency department visits, and inpatient hospitalizations were significantly higher in HIV-infected veterans with alcohol problems than in HIV-infected veterans without alcohol problems. We did not find a consistent interaction effect between alcohol problems and HIV status. CONCLUSION: Alcohol problems are associated with greater outpatient, emergency department, and inpatient health care utilization in HIV-infected and HIV-uninfected veterans. However, alcohol does not appear to have a stronger effect on health services use in HIV-infected veterans compared with HIV-uninfected veterans

More than 12 million people in the United States have coronary heart disease, the second leading cause of hospitalization in the United States. It is known that persons within racial minorities, specifically African Americans, have a higher prevalence of coronary heart disease, yet are much less likely to undergo invasive cardiac treatment interventions. An invasive intervention commonly used to treat coronary heart disease is coronary artery bypass grafting, with over 140,000 operations performed annually in the United States. However, blacks are known to experience higher post-coronary artery bypass graft morbidity and mortality. The causes for racial disparities in post-coronary artery bypass graft outcomes are not well known but may include factors related to the individual, provider, system, and society/environment, either alone or in combination. The purpose of this article is to provide an overview of the literature regarding disparities in the health and healthcare of black patients with coronary heart disease with respect to CABG, and examine potential hypotheses for variant outcomes after surgery
