HIV antibody testing of gay men in smaller US cities.

The incidence of new AIDS diagnoses among gay males indicates that risk reduction in smaller communities may be lagging behind that reported in larger cities. Contradictory evidence exists, largely from urban areas, concerning the utility of HIV testing as a means of promoting behavioural change. This study examined the relationship between HIV antibody testing and subsequent high-risk sexual behaviours among gay men in cities of 180,000 or fewer inhabitants. In February and March of 1992, male gay bar patrons in sixteen small US cities were administered an anonymous questionnaire concerning recent sexual behaviour and HIV testing history. Of the 1820 respondents, 28.1% had recently engaged in unprotected anal intercourse and 60.7% had been tested for HIV antibodies. Those who had been tested were more sexually active and reported more protected and safer sexual activities. Analyses at the individual and city levels converged to demonstrate that communities as well as individuals evidence increased self-protection in association with HIV antibody testing.

The locations of nonresidential out-of-hospital cardiac arrests in the City of Pittsburgh over a three-year period: implications for automated external defibrillator placement.

OBJECTIVES: To determine the locations of nonresidential out-of-hospital cardiac arrests (OHCAs) in the City of Pittsburgh and to determine whether there are "high-risk" locations that might benefit from placement of automated external defibrillators (AEDs). METHODS: This was a retrospective case review of paramedic calls for OHCA over a three-year period, in a mid-sized northeastern city. Cardiac arrests that were traumatic or for which the patients were dead on arrival (DOA) or had advanced directives for no resuscitation were excluded. Cardiac arrests that occurred in a public location (i.e., not a private residence) were categorized. RESULTS: A total of 971 OHCAs occurred in the City of Pittsburgh from January 1, 1997, to December 31, 1999. Of these, 575 (59%) occurred in private residences, and 396 (41%) occurred in nonresidential locations. Fifteen locations had at least one cardiac arrest per year for three years, accounting for 166 (43%) of the total nonresidential OHCAs. Twelve locations had two arrests during the three-year period, accounting for 24 (6%) of the total nonresidential OHCAs. One hundred ninety-four locations had a single episode of cardiac arrest, accounting for 51% of the OHCAs. Nursing homes and dialysis centers accounted for 178 (94%) OHCAs in the 27 locations that had two or more cardiac arrests. A local sports/events complex (Three Rivers Stadium) was the only other single location to have more than two cardiac arrests in the three-year study period, with a total of three. However, events at this complex are routinely staffed by paramedics equipped with defibrillators. CONCLUSION: The majority of nonresidential OHCAs occur as singular, isolated events. Other than nursing homes and dialysis centers, there were no identifiable high-risk locations for nonresidential OHCA within the City of Pittsburgh.

Obesity in inner-city African Americans.

OBJECTIVE: Obesity, a risk factor for chronic diseases, has a high prevalence in African Americans and low-income individuals. However, little is known about perceptions of overweight, attempts to lose weight, and strategies used to lose weight among African Americans in inner cities. DESIGN: A 1990 cross-sectional telephone survey (n = 1445) of north St Louis and central Kansas City, USA. RESULTS: Obesity was common (44%) in this sample of inner-city African Americans. The obese perceived themselves as overweight (70%) and were trying to lose weight (66%). The majority of the obese (68%) were both dieting and exercising to lose weight. Smoking prevalence was not higher among the obese or those trying to lose weight. Many of the obese had received medical advice recently on low-fat diets (51%) and had been advised to lose weight (40%). Factors independently associated with perception, attempts to lose weight and medical advice differed, but included degree of obesity. CONCLUSIONS: These results corroborate US national data that obesity is a public health problem in this population and that obese inner-city African Americans perceive themselves as overweight and are trying to lose weight, especially as degree of obesity increases. It also appears that smoking is not being used as a weight loss strategy and that the obese, as a group, are receiving some medical advice on low-fat diets. This information is critical for designing culturally sensitive weight-control programmes.

Speech and language therapy service delivery for bilingual children: A survey of three cities in Great Britain.

BACKGROUND: Speech and language therapy (SLT) managers are expected to ensure that there are appropriate services available for bilingual and multilingual clients in order to ensure an equitable service to all clients. However, there is a paucity of data available to inform service planning. AIMS: To identify the level to which SLT services in three UK cities meet the recommendations of The Royal College of Speech and Language Therapists (RCSLT) Good Practice Guidelines. Socio-demographic information is provided about the number of children from ethnic minorities in the population and the proportion of (bilingual) children from ethnic minorities on the speech and language therapy caseload. Based on this information, it is estimated whether there is proportionate representation of bilingual children on SLT caseloads, and whether services are in place to meet the needs of those clients. METHODS & PROCEDURES: Population statistics were gathered from Census data and data were gleaned from Local Education Authorities. The study used a combination of interview and postal questionnaires to SLTs, with particular emphasis on the issues that may affect service provision. OUTCOMES & RESULTS: As in previous studies, it was difficult to find reliable data. However, two of the three cities studied appeared to be offering a proportionate service to both monolingual and bilingual children in terms of the relative numbers of children on caseloads. Only one city was confident that their SLT service was fully meeting the RCSLT Good Practice Guidelines on bilingualism, although all three cities were aware of them and appeared to be making an effort at varying levels to address the principles of those guidelines. CONCLUSIONS: There is a need for a change in how data on linguistic diversity in society are collected and disseminated, both at a national level and within SLT services, so that informed decisions can influence the future of quality services to minority groups.

Generalizing the alcohol outlet-assaultive violence link: evidence from a U.S. midwestern city.

This study assessed the geographic association between rates of assaultive violence and alcohol-outlet density in Kansas City, Missouri. Data were obtained for sociodemographic factors, alcohol-outlet density, and rates of assaultive violence across 89 inner-city census tracts in Kansas City, Missouri. Hierarchical regression analysis indicated that sociodemographic variables predicted 61% (R2 = 0.61) of the variance in assaultive violence, but that an additional 9% (R2 = 0.09) of the variability in assaultive violence was explained by the density of alcohol outlets. Alcohol-outlet density contributed significantly to the explained variance of the regression model and was associated with higher rates of assaultive violence in this midwestern city.

Modifiers of the temperature and mortality association in seven US cities.

This paper examines effect modification of heat- and cold-related mortality in seven US cities in 1986-1993. City-specific Poisson regression analyses of daily noninjury mortality were fit with predictors of mean daily apparent temperature (a construct reflecting physiologic effects of temperature and humidity), time, barometric pressure, day of the week, and particulate matter less than 10 micro m in aerodynamic diameter. Percentage change in mortality was calculated at 29 degrees C apparent temperature (lag 0) and at -5 degrees C (mean of lags 1, 2, and 3) relative to 15 degrees C. Separate models were fit to death counts stratified by age, race, gender, education, and place of death. Effect estimates were combined across cities, treating city as a random effect. Deaths among Blacks compared with Whites, deaths among the less educated, and deaths outside a hospital were more strongly associated with hot and cold temperatures, but gender made no difference. Stronger cold associations were found for those less than age 65 years, but heat effects did not vary by age. The strongest effect modifier was place of death for heat, with out-of-hospital effects more than five times greater than in-hospital deaths, supporting the biologic plausibility of the associations. Place of death, race, and educational attainment indicate vulnerability to temperature-related mortality, reflecting inequities in health impacts related to climate change.

The epidemiology of multiple sclerosis in three Australian cities: Perth, Newcastle and Hobart.

An epidemiological survey of multiple sclerosis (MS) in three Australian cities, Perth, Newcastle and Hobart, was undertaken with its prevalence day being the national census day on June 30, 1981, exactly twenty years after a previous survey of the same cities. The relationship between increasing prevalence and increasing south latitude found in the 1961 survey was confirmed in this present study. Prevalence rates had increased significantly over the twenty years between the studies. Over the same time period incidence rates had also increased in Newcastle and Hobart but had remained essentially stable in Perth although these changes were not significant. The rise in prevalence was due to a combination of factors of differing importance in each city. These factors included better case ascertainment, increased recognition of the less severely disabled patient, increased survival time and differential immigration of a population at a higher risk of developing MS than the indigenous population. Finally, analysis of MS prevalence rates amongst migrant populations in Perth and Hobart suggested that either the risk of acquisition of MS may extend over a wider age range than is generally accepted or that environmental factors prevalent in the former city have modified disease expression there.

Effects of urban air pollutants on emergency visits for childhood asthma in Mexico City.

The metropolitan area of Mexico City, Mexico, has serious air pollution problems. Although air contaminants may contribute to clinical asthma, there are at present no data on the relation between air pollution exposure and childhood asthma in Mexico City. The authors reviewed data on emergency visits from January to June 1990 at one major pediatric hospital in Mexico City. They used a Poisson regression model to study the relation between the number of daily emergency visits for asthma and air pollutant levels. The levels of ozone and sulfur dioxide-exposure were significantly associated with the number of emergency visits for asthma. After adjustment for potential confounding factors, the multivariate regression model predicted that an increase of 50 ppb in the 1-hour maximum ozone level would lead to a 43% increase in the number of emergency visits for asthma on the following day. Exposure to high ozone levels (> 110 ppb) for 2 consecutive days increased the number of asthma-related emergency visits by 68 percent. The results of this study suggest that ozone exposure is positively associated with the number of children's emergency visits for asthma in Mexico City.

Measurements of indoor gamma radiation dose in At-Taif city, Saudi Arabia using CaSO4:Dy (TLD-900).

This paper describes measurements of indoor gamma radiation dose in At-Taif city, Kingdom of Saudi Arabia. CaSO(4):Dy thermoluminescence dosemeters were used for the detection of gamma radiation in 250 houses within the city. The values of indoor gamma radiation dose rate measured ranged between 90 and 221 nGy h(-1) for the time interval from September 2002 to September 2003. The measured dose varied with the type of house and season of the year. The highest average value 192 +/- 7 nGy h(-1) was measured inside apartments made of cement and brick (157-221 nGy h(-1)), and the lowest average value 92 +/- 6 nGy h(-1) in mud houses (58-117 nGy h(-1)). Intermediate values 154 +/- 5 nGy h(-1) (128-177 nGy h(-1)) and 167 +/- 9 nGy h(-1) (144-185 nGy h(-1)) were observed in large halls and villas, respectively. The average indoor gamma radiation dose rate received by the population of At-Taif city is 138 nGy h(-1) and its corresponding annual dose is 1211 muGy y(-1). The calculated mean effective dose to At-Taif city population, assuming an indoor occupancy factor of 80%, is 970 muSv y(-1).

A study of central-city hospital changes.

This study was initiated to determine the extent of hospital capacity reduction in large U.S. cities. In addition, hospital bed and service additions were analyzed. Study data indicate that between 1976 and 1978 more than 5,000 beds were closed in the 36 cities surveyed. This constitutes 2.7% of total hospital beds in those cities. Nearly half of the cities had no bed reduction at all, while seven had their supply diminished by more than 5%. Thirty-one emergency rooms and 13 outpatient facilities were also closed during the 2-year period, potentially affecting patient access. Health system agencies (HSAs) expressed approval of 73.4% of hospital closures and 54.4% of expansions, therefore expressing greater support of system shrinkage. Data on expected hospital changes (for the next year) was limited. However, opening and expansions are expected to occur at a slightly higher rate than during the 1976-78 period with fewer closures.

Care-seeking patterns of inner-city families using an emergency room. A three-decade comparison.

OBJECTIVES: Since World War II, the urban hospital emergency room has been a major source of medical care for inner-city poor families, many of whom receive Medicaid. Given the expensive and episodic nature of emergency room care, there has been renewed interest in enrolling Medicaid recipients into managed care plans to increase access to care and to reduce medical costs. Thus, the primary care physician, in many managed care plans, is expected to give prior approval for emergency room care in nonurgent situations. The goals of managed care may create tension between its requirements and historical patterns of inner-city families seeking care in an emergency room. In 1964, Alpert developed a typology that categorized inner-city families' patterns of seeking medical care in a pediatric emergency department (PED) by describing the relation between regular source of medical care and reliance on this source before the PED visit. In 1976, using the same typology, Alpert and Scherzer updated care-seeking patterns in Boston after the introduction of neighborhood health centers (NHCs) and Medicaid. In 1993, the typology is a method that can be used to assess the impact of managed care on PED utilization by inner-city families. This article compares the 1993 pattern of seeking PED care with that measured in 1964 and 1976. METHODS: In 1964, 1976, and 1993 families were interviewed as they sought care in a PED. Families were asked if they had a regular source of care, defined as the place where families take their child most often for either well or sick visits. A judgment was made as to whether or not the PED visit was coordinated with their regular source of care. Coordinated care was defined as having a regular source of care and attempting to contact the source before the PED visit. Uncoordinated care occurred when the family had a regular source and did not attempt contact, or had no regular source. RESULTS: In 1964, 63% of families reported a regular source of care compared with 89% in 1976 and 95% in 1993. The hospital was reported as the regular source of care by 57% of the respondents in 1964, by 31% in 1976, and 43% in 1993. Community-based sources (physicians and NHCs) were identified as a regular source of care by 43% in 1964, 69% in 1976, and 57% in 1993. In 1964, 55% of the families engaged in an uncoordinated pattern of seeking care compared with 64% in 1976 and 72% in 1993. CONCLUSIONS: Efforts to provide access to care through Medicaid, NHCs, and hospital-based primary care resulted in a greater percentage of families reporting a regular source of care; however, a majority of families continue to exhibit an uncoordinated pattern of seeking care. More families in 1993 did not contact their regular source before seeking care in the PED when compared with 1964 and 1976. For managed care plans to increase access and reduce costs, a shift in PED utilization patterns remains necessary. The primary care system must have the capacity to accommodate these changes and considerable patient education must occur if urgent care is to be provided outside the PED.

Evaluation of modified New York City carbohydrate medium for the speciation of Neisseria.

A comparative study of modified New York City carbohydrate medium, Minitek (BBL Microbiology Systems, Cockeysville, Md.) and cystine-trypticase agar was conducted for determination of the relative accuracies of these media in the identification of pathogenic Neisseria. Of 170 isolates of Neisseria gonorrhoeae, 169 were correctly identified by New York City carbohydrate media, 131 by Minitek, and 117 by cystine-trypticase agar. Of the 72 isolates of Neisseria meningitidis tested, all were accurately speciated by New York City carbohydrate media, whereas Minitek and cystine-trypticase agar identified 61 and 49 strains, respectively. The greater reliability of New York City carbohydrate media is accompanied by advantages not offered by the other media.

High prevalence of antibodies to herpes simplex virus type 2 among middle-aged women in Mexico City, Mexico: a population-based study.

BACKGROUND: Herpes simplex virus type 2 (HSV-2) is among the most prevalent sexually transmitted diseases worldwide. In Mexico there is a lack of population-based HSV-2 surveys. GOALS: To determine population-based HSV-2 seroprevalence and risk factors among women in Mexico City. STUDY DESIGN: A random sample of 730 women was identified among the residents of Mexico City. Women ages 25 to 85 years were selected from 3,694 households. Western blot serology testing was conducted on serum samples to determine HSV-2 type-specific serostatus. A structured questionnaire was administered, and multivariate analyses were performed to identify risk factors for HSV-2 seropositivity, which were stratified into two age categories: younger than 50 years of age and 50 years of age or older. RESULTS: The HSV-2 seroprevalence among female participants was 29.8%, with a significant trend of increasing HSV-2 prevalence for each higher level of age (P < 0.001). Female participants had a median age of 46 years and were predominantly monogamous (82.6%). The overall population-based seroprevalence estimated in Mexico City among women was 35.8%. The independent risk factors for HSV-2 seropositivity included a history of two or more sexual partners (odds ratio [OR], 2.2; 95% CI, 1.4-3.4), two or more sexual partners before first pregnancy (OR, 2.3; 95% CI, 1.4-3.7), cohabitation with partner (OR, 2.5; 95% CI, 1.3-4.7), and current vaginal douching (OR, 1.7; 95% CI, 1.2-2.6). CONCLUSIONS: Population-based HSV-2 seroprevalence is endemically high among middle-age women in Mexico City, and clearly is correlated with higher-risk sexual behavior. This elevated HSV-2 seroprevalence may reflect unrecognized HSV-2 transmission throughout life.

Folk remedy use in the inner city.

BACKGROUND: Folk remedies (FRs) are common in some minority communities within the United States. However, little information is available about the use of FRs in the inner city. The objectives of this study were to identify the prevalence and types of FRs used in the inner city, to characterize the population using FRs, and to study patient attitudes toward discussing FRs with physicians. METHODS: We interviewed 71 patients over the age of 18 who visited an inner city ambulatory clinic. RESULTS: The rate of FR use ranged from 10% to 50% among common medical conditions, with most patients (59%) using at least one remedy. Folk remedy use did not correlate with patient age. Most patients used FRs because they believed them to be efficacious, and most felt comfortable discussing FRs with their physicians. CONCLUSIONS: Inner city residents of all ages use FRs to treat illness. These FRs are benign and consist of common household items. Health care workers should feel comfortable discussing FRs with their patients since their patients are comfortable with the topic.

Quality assurance with regard to outcome and use of medical resources for patients hospitalized with acute chest pain: a comparison between a city university hospital and a county hospital.

This study aimed to test the hypothesis that there is a difference in mortality between patients hospitalized with acute chest pain in a university hospital and those hospitalized in a county hospital, and to describe differences in characteristics and use of medical resources in these two settings. All patients hospitalized at Sahlgrenska University Hospital in Göteborg (with a catchment population of 706 inhabitants/km(2)) and Uddevalla County Hospital (with a catchment population of 34 inhabitants/km(2)) with symptoms of acute chest pain during a registration period of 6 months were included in the study. A total of 1592 patients in the city hospital and 822 in the county hospital fulfilled the given criteria for inclusion. Patients in the urban area differed from those in the rural area in that they had a lower prevalence of previous angina pectoris and hypertension and a higher prevalence of previous cancer, previous percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting (CABG) and current smoking. On admission to hospital, patients in the urban area less frequently showed clinical signs of congestive heart failure and acute ischaemia on the electrocardiogram (ECG) but more frequently had a pathological ECG without signs of ischaemia and more frequently had a heart rate >100 beats/min. The use of medical resources differed between the two hospitals. Revascularization was more frequent in the city hospital and the use of -blockers in the county hospital. The overall 30 day mortality was 4.7% in the urban area and 4.3% in the rural area (P=0.74). When correcting for differences at baseline, the risk ratio for death in the county hospital versus the city hospital was 0.84 (95% confidence interval 0.51-1.40, P=0.53). In conclusion, among patients hospitalized with acute chest pain in a city university and a county hospital the mortality during the subsequent 30 days did not differ. However, there were differences in terms of the use of medical resources and in previous history, chronic medication prior to hospital admission and status on admission between the two cohorts.

The role of private physicians in STD control in two inner-city communities in Houston, Texas.

Although sexually transmitted diseases (STDs) are particularly widespread in poor, largely minority, inner-city areas, little is known about the role private physicians play in these communities in STD control. A cross-sectional mail survey of private physicians potentially involved in STD management in two inner-city communities in Houston, Texas with STD prevalence rates well above city, state, and national averages was conducted to find the level and type of STD care provided. Twenty-seven of 65 physicians completed the survey. The survey found that the preventive orientation among private providers of medical care in these inner-city communities has to be increased to effectively control STDs.

Food as a source of dioxin exposure in the residents of Bien Hoa City, Vietnam.

Recently, elevated dioxin levels, over 5 parts per trillion (ppt) 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), from Agent Orange was reported in 95% of 43 selected residents of Bien Hoa City, a city in southern Vietnam near a former air base used for Agent Orange-spraying missions. Agent Orange herbicide, contaminated with TCDD, was sprayed in Vietnam between 1962 and 1971 primarily for use as a defoliant. Typical blood TCCD levels are 2 ppt in Vietnamese, but levels are as high as 413 ppt in Bien Hoa City. Elevated TCDD was found in children born many years after Agent Orange spraying ended and in immigrants from non-Agent Orange-sprayed parts of Vietnam, which documented new exposures. Extremely elevated soil TCDD samples, over 1 million ppt, and elevated TCDD in sediment were found in some nearby areas such as Bien Hung Lake. The primary route of intake of almost all dioxins in humans is food. However, in our prior studies in Bien Hoa, food was unavailable for dioxin analysis so the route of intake was not confirmed. In the 1970s, while Agent Orange was still being sprayed, elevated human milk TCDD levels as high as 1850 were detected in milk from Vietnamese people living in Agent Orange-sprayed areas where consumption of fish was high. Furthermore, also in the 1970s, elevated TCDD levels (up to 810 ppt) were found in fish and shrimp from the same area as the milk donors. In the 1980s, we found elevated TCDD and also other organohalogen levels in human tissue, pork, fish, a turtle, and a snake in Southern Vietnam. For these reasons, we recently collected food from Bien Hoa and analyzed it for dioxins, polychlorinated biphenyls (PCBs), DDT and its metabolites, and other organochlorines. We found marked elevation of TCDD, the dioxin characteristic of Agent Orange, in some of the food products, including ducks with 276 ppt and 331 ppt wet weight, chickens from 0.031-15 ppt wet weight, fish from 0.063-65 ppt wet weight, and a toad with 56 ppt wet weight. Usual TCDD levels in food are less than 0.1 ppt. Total TEQ for ducks was from 286-343 ppt wet weight or 536 ppt and 550 ppt lipid; for chickens from 0.35-48 ppt wet weight or 0.95-74 ppt lipid, for fish from 0.19-66 ppt wet weight or 3.2 ppt and 15,349 ppt lipid, and the toad was 80 ppt wet weight and 11,765 ppt lipid. Interestingly, this study did not find elevated levels of TCDD in the pork and beef samples. Clearly, food, including duck, chicken, some fish, and a toad, appears responsible for elevated TCDD in residents of Bien Hoa City, even though the original Agent Orange contamination occurred 30-40 years before sampling. Elevated levels of PCBs and DDT and its metabolites were found in some food samples. Furthermore, measurable levels of hexachlorocyclohexanes (HCH) and hexachlorobenzene (HCB) were found in a wide range of measurable levels. All of the 11 dioxin-like PCBs measured and presented plus 6 dioxins in addition to TCDD and 10 dibenzofurans contributed to the total dioxin toxicity (TEQ). However, when elevated, TCDD frequently contributed most of the TEQ. Thirty-six congeners from 7 classes of chemicals were measured in each of the 16 specimens providing a total of 576 congener levels.
