Violence and HIV-related risk among young men who have sex with men.

Limited research has been conducted on threats or violence by family members and sexual partners against young men who have sex with men (MSM). Young MSM, aged 15-22 years, who attended public venues in New York City were enrolled in an anonymous, cross-sectional HIV seroprevalence and risk-behavior study. About two-thirds (68%) of the young MSM reported ever experiencing threats or violence from either family or partners and 25% reported threats or violence by both family and partners. In multivariate analysis, threats or violence by partners was significantly associated with older age, a history of forced sex and a history of running away from home. Recent unprotected anal sex and club drug use were significantly associated with a history of threats or violence by both family and partners. HIV prevention interventions need to include multiple factors that may have an impact on risk, including substance use and abuse, anti-violence and other mental-health issues.

Impact of chronic oral anticoagulation on management and outcomes of patients with acute myocardial infarction: data from the RICO survey.

OBJECTIVE: To determine the prevalence of chronic oral anticoagulant drug treatment (COA) among patients with acute myocardial infarction (AMI) and its impact on management and outcome. METHODS: All patients with ST segment elevation AMI on the RICO (a French regional survey for AMI) database were included in this analysis. COA was defined as continuous use >or= 48 hours before AMI. RESULTS: Among the 2112 patients with ST elevation myocardial infarction (STEMI), 93 (4%) patients were receiving COA. These patients were older and more likely to have a history of hypertension, diabetes and prior myocardial infarction than patients without COA. In addition, fewer patients who received COA underwent reperfusion therapy or received an antiplatelet agent (aspirin/thienopyridines). Moreover, patients receiving COA experienced a higher incidence of in-hospital major adverse events (death, recurrent myocardial infarction or major bleeding, p = 0.005). Multivariate analysis showed that only ejection fraction, current smoking and multiple vessel disease, but not COA, were independent predictive factors for major adverse events. In contrast, COA was an independent predictive factor for heart failure when adjusted for age, diabetes, creatinine clearance, reperfusion, heparin and glycoprotein IIb/IIIa inhibitors (odds ratio 2.06, CI 95% 1.23 to 3.43, p = 0.005). CONCLUSION: In this population based registry, patients with STEMI with prior use of COA constituted a fairly large group (4%) with an overall higher baseline risk profile than that of patients without COA. Fewer in the COA group received reperfusion therapy or aggressive antithrombotic treatment and they experienced more adverse in-hospital outcomes. Thus, further studies are warranted to develop specific management strategies for this high risk group.

[Atrial fibrillation during myocardial infarction with and without ST segment elevation].

INTRODUCTION: The occurrence of atrial fibrillation (AF) in the acute phase of myocardial infarction with ST segment elevation is common and responsible for an excess hospital mortality. The aim of this work was to define the incidence, predictive factors, and the prognostic impact of AF during MI with and without raised ST segment in the RICO study. PATIENTS AND METHODS: Between January 2001 and July 2003, 1701 patients were included in this study: 130 (7.6%) had AF in the first 24 hours of management (AF+ group); 1571 (92.4%) remained in sinus rhythm (AF- group). RESULTS: Among the 1701 patients included in this study, 1197 (70.4%) had MI with raised ST and 504 (29.6%) had MI without raised ST. The incidence of AF was identical whatever the type of MI (7.6% with raised ST versus 7.7% without, p=0.334). The presence of Killip class >2 on admission and chronic obstructive pulmonary disease were independent predictive factors for the occurrence of AF (OR=3.84, p=0.007, and OR=2.47, p=0.014 respectively). The presence of AF was significantly associated with the occurrence of ventricular arrhythmia and/or cardiovascular mortality during admission in the non-selected MI population whatever the type of MI (raised ST ; AF+; 34% and AF-; 18%, p<0.01 versus without raised ST; AF+; 36% and AF-; 16%, p = 0.01). CONCLUSION: This study provides evidence that the incidence of AF during the first 24 hours of MI, as well as its poor prognosis, are identical whether or not there is ST segment elevation.

N-terminal pro-brain natriuretic peptide levels in patients with non-ST-elevation myocardial infarction.

METHODS AND RESULTS: 101 patients hospitalized for acute non-ST-elevation myocardial infarction (NSTEMI) were included in the study. Median N-terminal fragment of the brain natriuretic peptide (BNP) prohormone (Nt-proBNP) plasma level was 136 (40-335) pmol/l. Patients with increasing levels of troponin I [from low (0.1-10 ng/ml), intermediate (10-40 ng/ml) to high (> or =40 ng/ml) levels] had significantly increased levels of Nt-proBNP (p < 0.05). High-risk patients classified by a high PURSUIT score (i.e. supramedian) had significantly increased Nt-proBNP levels compared to patients with low scores (p < 0.001). Moreover, patients with in-hospital events (death, recurrent MI or clinical heart failure: 27%) had significantly increased median levels of Nt-proBNP compared to event-free patients (184 vs. 105 pmol/l, p = 0.02). CONCLUSION: Our data in an unselected population of NSTEMI patients indicate that high levels of circulating Nt-proBNP levels are associated with an increased risk of early cardiovascular events.

[Non-revascularisation of acute coronary syndrome with ST elevation].

National therapeutic strategies in acute coronary syndromes (ACS) required revaluation, especially with regards to reperfusion. RICO is an observatory of ACS in the Côte d'Or district. Between January 1st 2001 and April 31st 2003, the cases of 706 patients with ACS and persistent ST elevation or appearances of left bundle branch block eligible for revascularisation (admitted < 12 hours after onset of symptoms and no contra-indications to thrombolysis), were reviewed. The number of revascularised patients was 488 (69%) and 218 (31%) were not revascularised. Thrombolysis was the most commonly used method of revascularisation (66%) in this district: 34% underwent primary angioplasty. Multivariate analysis showed only three independent predictive factors of non-reperfusion during the acute phase. They were: age (> or = 75 years) (p < 0.001), left bundle branch block (p = 0.002) and hospital admission > or = 6 hours after onset of symptoms (p < 0.001). These results confirm the utility of developing networks to improve the efficacy of management and reduce the delay before hospital admission. They also identify specific population groups, the elderly for example, who require specific therapeutic strategies for coronary revascularisation in ACS.

[Application of risk stratification scores in acute myocardial infarction. Results of RICO (observation of infarction in the Ivory Coast)].

Several risk stratification scores for myocardial infarction have been developed in recent years, based on clinical trials. The object of this study was to assess the application of these scores in an unselected population of myocardial in farction in a French department. One thousand and fifty-four patients with acute myocardial infarction were included in the RICO observatory in the Côte d'Or. Those with ST elevation (SST), N = 746, had 30 day-mortality rates which increased with the TIMI and GUSTO scores (khi2 tendency, p < 0.001). There was a good discriminatory power of both these scores (correlations of 0.71 and 0.69 respectively). Similarly, logistic regression analysis showed a significant relationship between TIMI and GUSTO scores and 30 day mortality (p < 0.001). No correlation was observed between mortality and increased TIMI score in cases of infarction without ST elevation, N = 308, p = 0.344. Moreover, this score had a low discriminatory value in the study population with a correlation of 0.54. On the other hand, regression analysis showed a strong predictive value of the PURSUIT score in infarction without ST elevation for mortality. In addition, there was a correlation between death and the value of this score (p < 0.05). This score also showed a good discriminatory power with a correlation of 0.71. This study shows that, in an unselected population, risk stratification scores may be used as a routine in myocardial infarction, especially in cases with ST elevation.

[Beneficial effects of direct call to Emergency Medical Services on time delays and management of patients with acute myocardial infarction. The RICO (obseRvatoire des Infarctus de Côte-d'Or) data].

The influence of direct calls to specialized Emergency Medical Services in case of suspected myocardial infarction has not been extensively studied. The RICO registry is an exhaustive registry implemented in all six institutions participating in primary care of patients with acute myocardial infarction in one French administrative department (Côte-d'Or). From January 2001 to October 2001, 322 patients were admitted for acute myocardial infarction, among whom only 57 (18%) had directly called emergency medical services after the onset of symptoms. The baseline characteristics of patients who had directly called the emergency services were not different from those of the patients who had not. However, the time from symptom onset to first medical intervention (48 versus 105 minutes, p = 0.02) and from first medical intervention to hospital admission (60 versus 103 minutes, p = 0.02) were markedly shorter in patients who had directly called the emergency medical services. This resulted in a significant increase in the use of reperfusion therapy (70% versus 38%, p = 0.003), including a higher proportion of primary angioplasty (33% versus 20%, p = 0.04). This study documents the beneficial effect of a direct call to the Emergency Medical Services by the patients themselves. Too few patients, however use this opportunity and actions should be taken for informing the lay public of the benefits of this medical service.

[Sarcoidosis during the treatment of hepatitis C by interferon-alpha and ribavirin: 2 cases].

INTRODUCTION: Interferon-alpha (IFN alpha) used to treat chronic hepatitis C can be responsible for some side effects. We report two cases of sarcoidosis which appeared in patients treated with IFN alpha and ribavirin for chronic hepatitis C. EXEGESIS: A first patient, treated for 5 months with IFN alpha and ribavirin because of chronic hepatitis C, after the failure of a first treatment with IFN alpha alone, was hospitalized for dyspnea. The chest X-ray and scanner revealed an interstitial syndrome and mediastinal adenopathies. Biopsies of bronchial spurs revealed epithelioid and giganto-cellular granuloma. After discontinuation of antiviral treatment and starting corticosteroid therapy, the evolution was favourable but viremia reappeared. A second patient with IFN alpha and ribavirin for 4 months because of chronic hepatitis C (after the failure of a first treatment with IFN alpha alone) was hospitalized for fever, arthralgias, erythema nodosa and modification of previous skin scars. The biopsy of a scar showed an epithelioid and giganto-cellular granuloma. After discontinuation of antiviral therapy and starting corticosteroid treatment, the evolution was favourable. CONCLUSION: Some publications mention occurrence of sarcoidosis during IFN alpha therapy, occasionally associated with ribavirin, disappearing after discontinuation of the treatment, though sometimes corticotherapy is necessary. The roles of IFN alpha and ribavirin are discussed.

HIV-1 seroprevalence in chest clinic and hospital tuberculosis patients in New York City, 1989-1991.

OBJECTIVE: To describe more fully HIV-1 and tuberculosis (TB) coinfection in TB patients attending New York City Department of Health chest clinics (1989-1991) and one inner-city hospital (1990-1991). DESIGN: An unlinked serosurvey using HIV-1-antibody testing of remnant blood specimens collected for routine medical purposes. SUBJECTS: A total of 1414 clinic and 856 hospital patients. OUTCOME MEASURES: HIV seropositivity and TB infection/disease. RESULTS: A total of 327 (23%) of the clinic patients were HIV-1-positive, with a significantly higher seroprevalence in men (29 versus 15%, P < 0.001) and in young and middle-aged adults aged 30-50 years (P < 0.001). HIV-1 prevalence by TB diagnostic class was: class 2 (purified protein derivative-positive and chest radiograph-negative), 11% (64 out of 570); class 3 (active disease), 34% (197 out of 582); class IV (old/inactive disease), 30% (39 out of 130). Of the hospital patients 487 (57%) were HIV-1-positive. HIV-1 seroprevalence was 55% for those who were identified or believed to be HIV-1-negative on admission as indicated on the medical chart. HIV-1 seroprevalence in the clinic population decreased initially, but later increased, although not to study onset levels. CONCLUSIONS: There is considerable overlap between the TB and HIV epidemics in New York City; a part of the increasing TB incidence may be independent of HIV coinfection. The control of TB will necessitate prompt diagnosis of TB and HIV-1, appropriate TB treatment and/or chemoprophylaxis, and a greater commitment to tackle the social conditions associated with the spread of the disease.
