Effects of disengagement coping with HIV risk on unprotected sex among HIV-negative gay men in New York City.

Objective: This study examined how disengagement coping with HIV risk mediated the association between internalized homophobia and unprotected anal intercourse (UAI) and how sexual encounters in public venues (public sex) and drug use moderated the association between disengagement coping and UAI among HIV-negative gay men. Disengagement coping included fatalistic beliefs about maintaining HIV-negative seronegative serostatus (fatalism), optimistic attitudes toward medical seriousness of HIV infection and reduced concern about HIV risk due to highly active anti-retroviral therapies (optimism), and negative affective states associated with sexual risk (anxiety). Design: A survey was conducted among 285 HIV-negative gay men at an HIV prevention counseling program in New York City. Main Outcome Measures: Sexual risk was defined as having had UAI with nonprimary partners in the past 6 months. Results: In addition to the positive association between internalized homophobia, disengagement coping, and UAI, fatalism mediated the association between internalized homophobia and UAI; and optimism mediated the association between anxiety and UAI. A significant moderation effect of public sex was found between fatalism and UAI. Conclusions: The findings highlight the importance of understanding disengagement coping as it affects sexual risk practices among HIV-negative gay men in the continuing epidemic.

The heroin epidemic in New York City: current status and prognoses

Since 1989, heroin production worldwide has risen; in New York City, as its purity rose and prices fell, street-level markets were restructured and offered heroin in addition to cocaine and crack (which had been popular during the 1980s). While officials estimate that there are between 500,000 and one million hard-core, chronic heroin users nationwide, evidence of supplemental users heralding another heroin era includes: more overdoses and overdose deaths, greater demand for treatment, larger seizures of heroin at all levels of distribution and related arrests, and broader media coverage. In this article, the authors describe the characteristics of populations in which there may have been a percentage increase of new users, such as young middle- or upper-class European-Americans, young Puerto Ricans and recent Haitian and Russian immigrants. The abstinence of young African-Americans is also noted. The article ends with a preliminary needs assessment of the new users in the areas of health (including AIDS), housing, employment, treatment, arrest and imprisonment.     

Dietary intakes of middle-aged European, Maori and Pacific Islands people living in New Zealand

AIM: To compare dietary intakes of Maori, Pacific Islands and European men and women in New Zealand. METHODS: A food frequency questionnaire was used to calculate nutrient intakes of 5523 New Zealand workers aged 40 years and over (3997 men, 1524 women) from a cross-sectional survey carried out between 1988 to 1990. RESULTS: Compared with European men and women, Maori women and Pacific Islands men and women consumed larger amounts of total energy per day. Age-adjusted nutrients expressed as percentage contribution to total energy intakes showed that Maori and Pacific Islands men and women consumed less carbohydrate, fibre and calcium, and more protein, fat, saturated fat and cholesterol than European men and women, respectively. These results were consistent with fewer servings of cereal and cheese per month, and more servings of red meats, fish and eggs in Maori and Pacific Islands participants compared with Europeans, after adjusting for age and total energy intakes. Pacific Islands men and women also consumed more servings of chicken, fewer cups of milk and fewer servings of fruit per month compared to Europeans. Maori men and women consumed more slices of bread and fewer servings of vegetables per month compared to European men and women. CONCLUSIONS: There were striking differences in dietary habits, food selections and cooking practices between European, Maori and Pacific Islands participants. Dietary intakes of Maori workers were closer to those of Europeans than those of Pacific Islands participants. Ethnic differences were due to larger portion sizes and increased frequency of most foods in Maori and Pacific Islands participants.     

The use of legal action in New York City to ensure treatment of tuberculosis

BACKGROUND AND METHODS: After an increase in the number of cases of tuberculosis, New York City passed regulations to address the problem of nonadherence to treatment regimens. The commissioner of health can issue orders compelling a person to be examined for tuberculosis, to complete treatment, to receive treatment under direct observation, or to be detained for treatment. On the basis of a review of patients' records, we evaluated the use of these legal actions between April 1993 and April 1995. RESULTS: Among more than 8000 patients with tuberculosis, regulatory orders were issued for less than 4 percent. Among patients with a variety of social problems, only a minority required regulatory intervention: 10 percent of those with injection-drug use, 16 percent of those with alcohol abuse, 17 percent of those who were homeless, 29 percent of those who used "crack" cocaine, and 38 percent of those with a history of incarceration. A total of 150 patients were ordered to undergo directly observed therapy, 139 patients to be detained during therapy, 12 patients to be examined for tuberculosis, and 3 patients to complete treatment. These 304 patients had a median of three prior hospitalizations related to tuberculosis and one episode of leaving the hospital against medical advice. Repeatedly noncompliant patients and those who left the hospital against medical advice were more likely than others to be detained. The median length of detention was 3 weeks for infectious patients and 28 weeks for noninfectious patients. As compared with patients ordered to receive directly observed therapy, the patients who were detained remained infectious longer, had left hospitals against medical advice more often, and were less likely to accept directly observed therapy voluntarily. Altogether, excluding those who died or moved, 96 percent of the patients completed treatment, and 2 percent continued to receive treatment for multidrug-resistant tuberculosis. CONCLUSIONS: For most patients with tuberculosis, even those with severe social problems, completion of treatment can usually be achieved without regulatory intervention. Patients were detained on the basis of their history of tuberculosis, rather than on the basis of their social characteristics, and the less restrictive measure of mandatory directly observed therapy was often effective.     

Declining seroprevalence in a very large HIV epidemic: injecting drug users in New York City, 1991 to 1996

OBJECTIVES: This study assessed recent trends in HIV seroprevalence among injecting drug users in New York City. METHODS: We analyzed temporal trends in HIV seroprevalence from 1991 through 1996 in 5 studies of injecting drug users recruited from a detoxification program, a methadone maintenance program, research storefronts in the Lower East Side and Harlem areas, and a citywide network of sexually transmitted disease clinics. A total of 11,334 serum samples were tested. RESULTS: From 1991 through 1996, HIV seroprevalence declined substantially among subjects in all 5 studies: from 53% to 36% in the detoxification program, from 45% to 29% in the methadone program, from 44% to 22% at the Lower East Side storefront, from 48% to 21% at the Harlem storefront, and from 30% to 21% in the sexually transmitted disease clinics (all P < .002 by chi 2 tests for trend). CONCLUSIONS: The reductions in HIV seroprevalence seen among injecting drug users in New York City from 1991 through 1996 indicate a new phase in this large HIV epidemic. Potential explanatory factors include the loss of HIV-seropositive individuals through disability and death and lower rates of risk behavior leading to low HIV incidence.     

The epidemiology and causes of injuries resulting in hospitalization in New York City: 1990-1992

The purpose of this study is to present data on the distribution and etiology of nonfatal injuries resulting in hospital discharges in New York City (NYC). Records of all NYC residents discharged for injuries from acute stay hospitals 1990-1992 were tabulated. Injuries from surgical and medical procedures, adverse effects of drugs in therapeutic use, and late effects of injury were excluded. The results indicate that there was a marked geographic variation in rates: higher rates of assaults, self-inflicted injuries, burns, unintentional injuries from firearms, and injuries to bicyclists in disadvantaged neighborhoods. The data show that injuries in NYC have distinctive features that should form the basis for targeted prevention activities.     

Acculturation and breast cancer screening among Hispanic women in New York City

Surfactant protein D (SP-D), which has structural homology to C-type lectin binding regions, may play a role in host defense and has no known surfactant function. Because other surfactant proteins have been shown to be increased after prolonged periods of hyperoxia, we sought to evaluate the early effects of hyperoxia (95% O2) on expression of SP-D in the adult male rat lung. Animals were exposed to air or to 12, 36, or 60 h of 95% O2. Northern blot analysis of total lung RNA revealed marked SP-D mRNA increases at 12 h 95% O2 compared with air-exposed controls, with decreasing expression to near that of air-exposed animals by 60 h. Semiquantitative in situ RNA hybridization demonstrated parallel results, with increased numbers of labeled alveolar epithelial (AE) and bronchiolar epithelial (BE) cells at 12 h and increased intensity of labeled alveolar cells, compared with air-exposed controls. After 60 h of exposure to 95% O2, mRNA label intensity in AE and BE was decreased to levels near those seen in air-exposed animals. In contrast, Western blotting showed a decline in total lung SP-D with 95% O2 exposure, beginning at 12 h and continuing at 36 and 60 h, respectively. Semiquantitative immunohistochemistry demonstrated a decline in AE labeling parallel to the total lung Western blot results, but labeled total BE cell numbers increased (P = 0.10). Hyperoxia had differential effects on SP-D abundance in AE and BE cells, and therefore may influence the availability of SP-D to bind microbial pathogens in the airways depending on cell type and location.     

People living with HIV infection who attend and do not attend support groups: a pilot study of needs, characteristics and experiences

People living with Human Immunodeficiency Virus (HIV) confront a myriad of stressors over the course of their infection. Social support groups offer a means of addressing the support needs of people living with HIV. In the present study, 34 persons who had attended HIV support groups and 29 who had not attended groups completed measures of distress, coping, and social connectedness, and participated in open-ended interviews concerning their support group experiences. Results showed that those who attended support groups knew they were HIV-seropositive for a longer time, reported less emotional distress, and had more social contact than did non-attenders. However, non-attenders endorsed avoidant coping strategies to a greater extent. Analyses showed that time since testing positive accounted for differences between groups in social connectedness but not differences in anxiety, depression, or avoidance coping. Thus, HIV-seropositive persons become socially reconnected with time, but individuals with avoidant coping styles experience greater emotional distress and are unlikely to seek support groups. A sizeable proportion of people with HIV may therefore need supportive interventions, particularly nearer to the time that they test HIV-seropositive.     

Risk factors and outcome of human immunodeficiency virus-infected patients with sporadic multidrug-resistant tuberculosis in New York City

The discovery of neuroendocrine differentiation in hormone-refractory prostatic adenocarcinoma has opened a potentially new therapeutic approach in this group of patients with a poor prognosis and few effective therapy modalities. Based on previous findings of increased uptake of 11C-5-hydroxytryptophan (11C-5-HTP) in neuroendocrine tumours using the PET technique, this tracer was applied in the study of 10 patients with metastatic hormone-refractory prostatic adenocarcinoma. In three patients, the study was repeated after treatment. An increased uptake of 11C-5-HTP was observed in all investigated skeletal lesions, although the magnitude of the uptake was moderate. The difference between the standard uptake values (SUV) in normal bone and metastatic lesions was significant (p < 0.001). A kinetic analysis of the uptake of 11C-5-HTP demonstrates an increase during the first minutes followed by a wash-out and a stabilization of the tissue/blood ratio at about 2. The Patlak plots demonstrated a gradual increase in the transport rate during the first 20 to 30 min, after which a constant level was observed. The SUV varied between patients and between lesions over time and treatment. The uptake of 11C-5-HTP discriminates metastatic lesions from normal bone and may thus aid in the diagnosis and, potentially, in treatment monitoring of metastatic hormone-refractory prostatic adenocarcinoma. Uptake kinetics are characterized by a wash-out and cannot alone be used as proof of neuroendocrine differentiation in hormone-refractory prostatic adenocarcinoma.     

Medical-resource use for suspected tuberculosis in a New York City hospital

OBJECTIVE: To compare resource use by diagnostic outcome among hospital admissions during which tuberculosis (TB) was suspected. DESIGN: Retrospective study based on chart review and microbiology laboratory data. SETTING: The department of medicine in a municipal hospital serving central Brooklyn, New York. PARTICIPANTS: We identified all adult admissions in 1993 during which TB was suspected. We assigned each admission to one of four mutually exclusive groups defined by the results of microbiological tests (acid-fast bacilli [AFB] smear and culture): culture-positive and smear-positive (C+S+); culture-positive and smear-negative (C+S-); culture-negative and smear-positive (C-S+); or culture-negative and smear-negative (C-S-). Each admission was divided into two separate periods to which the utilization of medical resources was assigned: the diagnostic and the postdiagnostic periods, which were separated by the date of receipt of the first definitive culture report. RESULTS: Data on 519 admissions (93 C+S+; 57 C+S-; 30 C-S+; and 339 C-S-) were analyzed. Although C+S+ were more likely than other groups to have an admitting diagnosis of TB, approximately one quarter of the admissions without TB (C-S+, C-S-) were admitted with the principal diagnosis of TB. For the four groups, C+S+, C+S-, C-S+, and C-S-, the respective rates of TB isolation and anti-TB treatment, and median lengths of isolation were 98%, 87%, and 34 days; 74%, 74%, and 7 days; 83%, 83%, and 15 days; and 44%, 29%, and 0 days. During the diagnostic period, the rate and length of isolation were similar in the AFB-smear-positive groups (C+S+ and C-S+). We estimated that admissions without culture-proven TB (C-S+ and C-S-) accounted for 3,174 (36%) of the 8,712 days of TB isolation expended and for 65% of the 16,671 days of anti-TB treatment. The vast majority of this resource consumption (2,737 [86%] of 3,174 days of isolation) occurred during the diagnostic period before a definitive culture result was known. CONCLUSIONS: Our results suggest that prolonged diagnostic uncertainty and misclassification of cases due to false-positive and false-negative smears are associated with substantial medical-resource consumption. New diagnostic modalities that reduce the period of diagnostic uncertainty could reduce the utilization of resources later found to be unnecessary.     

Women who have sex with other women: HIV seroprevalence in New York State counseling and testing programs

This report provides HIV seroprevalence data for women who are sexually active with women (WSW) choosing to access services in four of New York State's counseling and testing programs from January 1993 to June 1994. During that period, these programs tested 27,370 women. When questioned about sexual activity since 1978, 3.7% of these women reported sexual activity exclusively with women, 5.3% reported sexual activity with both women and men and 90.1% reported sexual activity exclusively with men. HIV seroprevalence in women sexually active exclusively with women in this sample was calculated at 3.0%, at 4.8% in women sexually active with both women and men and at 2.9% in women sexually active exclusively with men. According to the self-reported data in this study, injecting drug use is, by far, the predominant risk factor for seropositive WSW. Significant HIV-related public health/preventative implications for WSW and their service providers are suggested by this data, including the need for prevention education targeted to WSW who are IDUs, the need to provide culturally sensitive education to WSW detailing safer sexual behaviors both with women and with men as well as the need for evaluation of all risk factors when providing risk reduction education to WSW.
