The health effects of living near cement kilns; a symptom survey in Midlothian, Texas.

Cement kilns are major sources of toxic air emissions. Regulations based on demonstrated concentrations of specific chemicals, and risk assessments with inherent limitations and uncertainties, are the current methods of preventing exposure to 'unsafe' emission levels. Monitoring data are frequently incomplete. These limitations mandate that residents residing near cement kilns be evaluated for adverse health effects. This study reports findings from a symptom survey conducted in Midlothian, Texas, which adds to the limited but growing body of knowledge showing that persons living near cement kilns are experiencing increased respiratory effects. This cross-sectional study uses randomized sampling and an extensive health questionnaire, covering 12 physiological systems, to determine differences in reported health symptoms between the study community (Midlothian, Texas, n = 58) and the reference community (Waxahachie, Texas, n = 54). Findings indicate significant elevations in reported respiratory symptoms in the study community (p-value 0.002). Although the comparatively small sample size is a limitation, the fact that only 'respiratory effects' were highly significant supports the efficacy of this investigation. Respiratory effects would be the major anticipated outcome from the known exposures under investigation. This specificity of response (i.e., elevation in respiratory symptoms only), indicates that 'response bias' was not a significant factor in this study.

Adoption and institutionalization of the Child and Adolescent Trial for Cardiovascular Health (CATCH) in El Paso, Texas.

One goal of national health-promotion research is to disseminate and institutionalize experimentally tested programs in local communities. In 1997, the national Child and Adolescent Trial for Cardiovascular Health (CATCH) was chosen by the Paso del Norte Health Foundation as their first community-wide preventive health initiative for the El Paso, Texas/Juárez, México border region. With help from researchers at the University of Texas at Houston, evaluators from the University of Texas at El Paso, and the Region 19 Educational Services Center, CATCH was implemented in 18 Title I pilot schools. Known as the Coordinated Approach to Child Health 5 years later, the El Paso CATCH program has been embraced by the border community and reaches 108 elementary schools from New Mexico to West Central Texas. There are also plans to implement CATCH in Juárez. This article describes the institutionalization of CATCH in a predominately Hispanic, low income border region.

Private insurance for Medicaid recipients: the Texas experience.

Shifting financial risk from the public to the private sector is an increasingly attractive option to policymakers seeking to constrain Medicaid costs. This paper discusses the potential advantages and disadvantages of private insurance arrangements for Medicaid recipients and examines the Texas Purchased Health Services Program, the oldest and largest private insurance program for Medicaid recipients in the U.S. Our analysis of the Texas program suggests that while the political benefits are real, the administrative costs are substantial and the fiscal benefits uncertain. While overall benefits may outweigh costs in Texas, differing political and fiscal circumstances may alter the balance in other states considering private insurance arrangements.

Homeless individuals and drug-resistant tuberculosis in south Texas.

Drug-resistant tuberculosis was found in 21 percent of homeless individuals in New York City between 1982 and 1987. To see if this relationship existed in south Texas, we evaluated all admissions to a Texas Health Department facility with culture-proven tuberculosis. Four hundred forty-three patients were admitted between September 1987 and October 1990. Twenty-six, (5.9 percent) of these patients were identified as homeless. Alcoholism, tobacco abuse, divorce, and unemployment were common demographic characteristics. Six male patients and one female patient (27 percent) had Mycobacterium tuberculosis resistant to one or more antituberculosis drugs. Five were Hispanic, one was white, and one was black. The six male patients had resistance to only one drug, either rifampin or ethambutol. The female patient had resistance to streptomycin, isoniazid, and rifampin. These findings illustrate that drug-resistant tuberculosis exists among homeless individuals in south Texas. As the number of homeless people increases, physicians need to recognize that pulmonary tuberculosis is a frequent infection in this population and that the causal mycobacteria may well be resistant to one or more antituberculosis agents.

Results of screening 1.9 million Texas newborns for 21-hydroxylase-deficient congenital adrenal hyperplasia.

OBJECTIVE: To assess results of newborn screening for 21-hydroxylase-deficient congenital adrenal hyperplasia (CAH) in Texas over 6 years of screening 1.9 million infants. METHODS: In 1989, CAH was incorporated into the ongoing Texas Newborn Screening Program, which requires two screens on each newborn. 17-Hydroxyprogesterone was assayed, without extraction, by radioimmunoassay of blood collected from heel sticks onto filter paper collection cards. Infants with elevated levels of 17-hydroxyprogesterone were referred for evaluation, and those considered to have CAH were studied with respect to disease characteristics. Data were collected by pediatric endocrinologists using standardized forms that included type of CAH, results of laboratory tests, treatment regimen, disease symptoms and signs, and, for girls, degree of genital virilization. RESULTS: The incidence of classic CAH in Texas is 1:16 008, with a ratio of salt-wasting to simple-virilizing of 2.7:1. A majority of infants detected were undiagnosed until screened, despite signs of salt-wasting or ambiguous genitalia. It was difficult to differentiate salt-wasting from simple-virilizing CAH in infants who were identified before the onset of adrenal insufficiency or electrolyte abnormalities. A substantial number of infants with nonclassic (NC) CAH also were detected. Not all infants were detected on the initial screen; 14% of infants with classic CAH and 87% with NC CAH were detected on the second routine screening test. CONCLUSIONS: Our findings confirm the benefits of newborn screening for CAH and the importance of a second screening test, and suggest that programs for newborn CAH screening must consider complex issues in diagnosis and treatment. These results also confirm that CAH is a continuum of disorders, rather than a disorder with discrete subtypes. In addition, the difficulties in differentiating CAH subtypes in newborns, and thus deciding appropriate treatment, and the high incidence of NC CAH suggest that standard diagnostic criteria and treatment regimens for CAH may need modification. Where screening exists, physicians will encounter more cases of CAH than in the past.

Texas passes first law for safe patient handling in America: landmark legislation protects health-care workers and patients from injury related to manual patient lifting.

On June 17,2005, Texas Governor Rick Perry (R) signed into law Senate Bill 1525, making Texas the first state in the nation to require hospitals and nursing homes to implement safe patient handling and movement programs. Governor Perry is to be commended for this heroic first stand for safe patient handling in America. The landmark legislation will take effect January 1, 2006, requiring the establishment of policy to identify, assess, and develop methods of controlling the risk of injury to patients and nurses associated with lifting, transferring, repositioning, and movement of patients; evaluation of alternative methods from manual lifting to reduce the risk of injury from patient lifting, including equipment and patient care environment; restricting, to the extent feasible with existing equipment, manual handling of all or most of a patient's weight to emergency, life-threatening, or exceptional circumstances; and provision for refusal to perform patient handling tasks believed to involve unacceptable risks of injury to a patient or nurse. Manually lifting patients has been called deplorable, inefficient, dangerous to nurses, and painful and brutal to patients; manual lifting can cause needless suffering and injury to patients, with dangers including pain, bruising, skin tears, abrasions, tube dislodgement, dislocations, fractures, and being dropped by nursing staff during attempts to manually lift. Use of safe, secure, mechanical lift equipment and gentle friction-reducing devices for patient maneuvering tasks could eliminate such needless brutality. Research has proven that manual patient lifting is extremely hazardous to health-care workers, creating substantial risk of low-back injury, whether with one or two patient handlers. Studies on the use of mechanical patient lift equipment, by either nursing staff or lift teams, have proven repeatedly that most nursing staff back injury is preventable, leading to substantial savings to employers on medical and compensation costs. Because the health-care industry has relied on people to do the work of machines, nursing work remains the most dangerous occupation for disabling back injury. Back injury from patient lifting may be the single largest contributor to the nursing shortage, with perhaps 12% of nurses leaving or being terminated because of back injury. The US health-care industry has not kept pace with other industries, which provide mechanical lift equipment for lifting loads equivalent to the weight of patients, or with other countries, such as Australia and England, which are more advanced in their use of modern technology for patient lifting and with no-lifting practices in compliance with government regulations and nursing policies banning manual lifting. With Texas being the first state to succeed in passing legislation for safe patient handling, other states are working toward legislative protection against injury with manual patient lifting. California re-introduced safe patient handling legislation on February 17, 2005, with CA SB 363, Hospitals: Lift Teams, following the September 22, 2004, veto of CA AB 2532 by Governor Arnold Schwarzenegger, who said he believes existing statutory protection and workplace safety standards are sufficient to protect health care workers from injury. Massachusetts HB 2662, Relating to Safe Patient Handling in Certain Health Facilities, was introduced December 1, 2004. Ohio HB 67, signed March 21, 2005 by Governor Bob Taft (R), creates a program for interest-free loans to nursing homes for implementation of a no-manual-lift program. New York companion bills AB 7641 and SB 4029 were introduced in April, 2005, calling for creation of a 2-year study to establish safe patient handling programs and collect data on nursing staff and patient injury with manual patient handling versus lift equipment, to determine best practices for improving health and safety of health-care workers and patients during patient handling. Washington State is planning re-introduction of safe patient handling legislation, after WA HB 1672, Relating to reducing injuries among patients and health care workers, was stalled in committee in February, 2005. Language from these state initiatives may be used as models to assist other states with drafting safe patient handling legislation. Rapid enactment of a federal mandate for Safe Patient Handling No Manual Lift is essential and anticipated.

Fatal occupational injuries of women, Texas 1975-84.

A review of Texas death certificates for 1975-84 identified 348 cases of fatal occupational injuries of civilian females. Homicides accounted for 53 per cent and motor vehicle-related injuries accounted for 26 per cent of the deaths. Injuries from firearms caused 70 per cent of the homicides. One hundred thirty-three deaths occurred to women employed in the retail trade industry; of these, 77 per cent resulted from homicide. Women workers in gasoline service stations, food-bakery-and-dairy stores, and eating-and-drinking places had especially high risks of homicide. Texas female heavy-truck drivers had the highest fatal-injury rate, with motor-vehicle-related injuries causing 89 per cent of their deaths. These results indicate that effective strategies to prevent fatal occupational injuries of Texas women will need to address the problems of workplace violence and the hazards posed by motor vehicles.

Welfare reform and the perinatal health and health care use of Latino women in California, New York City, and Texas.

OBJECTIVES: This study analyzed changes in the financing of prenatal care and delivery, the use of prenatal care, and birth outcomes among foreign-born vs US-born Latino women following enactment of the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) in August 1996. METHODS: We used a pre-post design with a comparison group. The sample consisted of resident Latinas in California, New York City, and Texas who delivered a live infant in 1995 or 1998. RESULTS: The proportion of births to Latinas that initiated prenatal care in the first 4 months of pregnancy increased for all foreign-born Latinas in California, New York City, and Texas between 1995 and 1998 (P <.05). Except for non-Dominicans in New York City, there was no increase in the proportion of low- or very-low-birthweight births among foreign-born vs US-born Latinas in the 3 localities between 1995 and 1996. CONCLUSIONS: There is little evidence from vital statistics in California, New York City, and Texas that PRWORA had any substantive impact on the perinatal health and health care utilization of foreign-born relative to US-born Latinas.

Childhood pesticide exposures on the Texas-Mexico border: clinical manifestations and poison center use.

OBJECTIVES: The purpose of this study was to describe differences in childhood pesticide exposures between counties on the Texas-Mexico border and nonborder counties. METHOD: The authors reviewed all pesticide exposures among children younger than 6 years reported to the South Texas Poison Center during 1997 through 2000. RESULTS: Nonborder counties had twice the reported exposure rate of border counties. Parents of border children were significantly less likely to contact the poison center after an exposure and more likely to have their children evaluated in a health care facility. CONCLUSIONS: Increasing residents' awareness of the poison center and identifying potential barriers to its use among residents of Texas-Mexico border communities may prevent unnecessary visits to health care facilities.

Usefulness of tobacco check boxes on death certificates: Texas, 1987-1998.

OBJECTIVES: We compared reports of deaths in which tobacco use was a contributing factor ("tobacco-associated deaths") before and after the addition to death certificates in Texas of a check-box question asking whether tobacco use contributed to an individual's death. METHODS: We examined Texas vital statistics files from 1987 to 1998. We calculated differences in percentages of reported tobacco-associated deaths (and 95% confidence intervals [CIs]) for the periods 1987 to 1992, before the addition of the check-box question, and 1993 to 1998, after the addition of the check-box. RESULTS: Reports of tobacco-associated deaths were significantly less frequent before addition of the check-box question (0.7%; 95% CI = 0.4%, 1.0%) than after addition of the question (13.9%; 95% CI = 13.0%, 14.7%). From 1993 to 1998, percentages of tobacco-associated deaths reported on the check-box question increased steadily. CONCLUSIONS: The addition of a tobacco-associated-death check box on Texas death certificates significantly increased reporting of tobacco use contributions to mortality.

Costs of diabetes in Texas, 1992.

OBJECTIVE: To estimate direct and indirect costs of diabetes in Texas in 1992. RESEARCH DESIGN AND METHODS: For most direct medical costs, we relied on third party and provider billing databases, including Medicare, Medicaid, VA facilities, public hospitals, and others. The researchers identified people with diabetes in the respective databases, located all records of their care, and sorted records as clearly, probably, or probably not attributable to diabetes on the basis of principal diagnoses. In most cases, costs were valued as allowable or paid charges. Some medical costs, such as private insurance, were estimated from national data and state surveys. Indirect costs included current short- and long-term disability costs and the discounted present value of future costs of mortality. Disability estimates relied on National Health Interview Survey (NHIS) data and U.S. Department of Labor wage data applied to Texas. Mortality estimates were based on death certificates. RESULTS: Total costs clearly or probably attributable to diabetes among Texans in 1992 were estimated at $4.0 billion. Direct medical costs were approximately $1.6 billion. Indirect costs were estimated at $2.4 billion. the largest direct costs were paid by Medicare. Most indirect costs were from long-term disability. CONCLUSIONS: This study demonstrates methods for conducting cost of illness studies at the state level. In a state like Texas, with a large and growing Mexican-American population, estimation of current and future economic costs of diabetes is vital for development of strategies to minimize social and economic consequences of diabetes.

Attributing inpatient medicare costs to diabetes among the Texas elderly.

OBJECTIVE: This study compares alternative methods for attributing hospital utilization and costs to diabetes. Findings from five "numerator" methods, found in the literature and based on presence of certain diagnoses or combinations of diagnoses in the billing records, were compared to benchmark findings derived from attributable risk calculations. RESEARCH DESIGN AND METHODS: Estimates of non-HMO, short-term, nonspecialized hospital stays, hospital days, and costs attributable to diabetes in Texas were derived from the 1995 Medicare inpatient database (MEDPAR) for persons aged at least 65 years at the end of 1994. Attributable risk calculations applied age-, sex-, and ethnicity-specific estimates of diabetes prevalence, based on the combined 1987-1994 National Health Interview Surveys, to 1995 Medicare non-HMO, Part A (hospital insurance) enrollment among the Texas elderly. Alternative prevalence estimates were based on the 1994-1996 Texas Behavioral Risk Factor Surveillance System. RESULTS: The five numerator methods yielded cost estimates that were 10, 10, 75, 144, and 172% of the benchmark estimate. CONCLUSIONS: This study documents great variation in diabetes cost estimates that might result from alternative methods for selecting diagnoses or combinations of diagnoses as criteria for attributing costs to diabetes. Whereas no method that ignores population prevalence yielded an accurate cost estimate, I suggest that further empirical study may be helpful in selecting those combinations of diagnoses that might, on average, reasonably estimate diabetes costs in situations where population denominators are unavailable or prevalence is unknown.

Transfer student and gender issues within the Department of Animal Science at Texas A&M University.

Graduates with a B.S. or graduate degree from the Department of Animal Science (1986 to 1996) of Texas A&M University were surveyed by mail to gather opinions on the curriculum and satisfaction with their degrees. The survey contained five Likert questions (1 = excellent, 4 = poor) regarding satisfaction with major, educational results, personal growth, professional development, and skills important for employment. Multiple-choice questions (n = 9) addressed education, background, job status, and gender. Surveys (n = 2,192) were sent to students, and 470 responded. The undergraduate respondents (n = 396) comprised 71.2% (n = 282) nontransfer students and 28.8% (n = 114) transfer students. Transfer students reported a mean grade point ratio (GPR) of 3.05 +/- 0.43 at Texas A&M University in comparison to a nontransfer student mean GPR of 3.03 +/- 0.45 for hours completed at Texas A&M University (P = 0.83). The results for time from graduation to full-time employment for transfer students were similar to those of nontransfer students (P = 0.95). Differences in current annual salary between transfer students and nontransfer students were apparent (P < 0.0001). Transfer students and nontransfer students reported similarly that courses within the department were valuable (P = 0.95) and not redundant (P = 0.08). The two groups similarly rated contributions to critical thinking (P = 0.59) and speaking (P = 0.38). Undergraduate respondents (n = 392) were 48.9% (n = 192) male and 51.1% (n = 200) female. Males and females reported a mean GPR of 3.02 +/- 0.46 and 3.07 +/- 0.43, respectively (P = 0.35). Differences in job search time (P < 0.0001), starting salary (P = 0.0004), and current salary (P < 0.0001) were apparent between genders; females were paid less and searched longer before finding their first job. Males and females responded similarly that courses were valuable (P = 0.16) and were taught effectively (P = 0.37) and that teaching assistants made positive contributions (P = 0.43). Females felt a lesser contribution to critical thinking ability, leadership ability, and technical expertise. Results suggest the continuance of current educational practices, but changes to specific issues should be initiated.

The Texas Medication Algorithm Project antipsychotic algorithm for schizophrenia: 2003 update.

BACKGROUND: The Texas Medication Algorithm Project (TMAP) has been a public-academic collaboration in which guidelines for medication treatment of schizophrenia, bipolar disorder, and major depressive disorder were used in selected public outpatient clinics in Texas. Subsequently, these algorithms were implemented throughout Texas and are being used in other states. Guidelines require updating when significant new evidence emerges; the antipsychotic algorithm for schizophrenia was last updated in 1999. This article reports the recommendations developed in 2002 and 2003 by a group of experts, clinicians, and administrators. METHOD: A conference in January 2002 began the update process. Before the conference, experts in the pharmacologic treatment of schizophrenia, clinicians, and administrators reviewed literature topics and prepared presentations. Topics included ziprasidone's inclusion in the algorithm, the number of antipsychotics tried before clozapine, and the role of first generation antipsychotics. Data were rated according to Agency for Healthcare Research and Quality criteria. After discussing the presentations, conference attendees arrived at consensus recommendations. Consideration of aripiprazole's inclusion was subsequently handled by electronic communications. RESULTS: The antipsychotic algorithm for schizophrenia was updated to include ziprasidone and aripiprazole among the first-line agents. Relative to the prior algorithm, the number of stages before clozapine was reduced. First generation antipsychotics were included but not as first-line choices. For patients refusing or not responding to clozapine and clozapine augmentation, preference was given to trying monotherapy with another antipsychotic before resorting to antipsychotic combinations. CONCLUSION: Consensus on algorithm revisions was achieved, but only further well-controlled research will answer many key questions about sequence and type of medication treatments of schizophrenia.

Autochthonous dermal leishmaniasis in Texas.

Over a 2-year period two cases of dermal leishmaniasis of special interest were recognized in Texas. The first occurred in 1972 in a 74-year-old woman who had residences in Dilworth and Gahzales, Gonzales County, and the other was in a 56-year-old man from Kenedy, Karnes County, in 1974. Both cases were biopsy- and culture-positive, and the second patient exhibited anti-Leishmania antibodies by indirect immunofluorescent antibody and direct agglutination tests. Epidemiologic investigation revealed no association between the two cases and suggested that both patients had acquired their infections locally in southern Texas. Moreover, serologic evidence of Leishmania infection was uncovered in a neighbor of the second case and in 3 dogs living nearby. Potential sylvatic reservoirs and arthropod vectors of the disease are resident in the area. Epidemiologic data suggest that dermal leishmaniasis is endemic in south-central Texas.

Reintroduction of dengue fever into the continental United States. I. Dengue surveillance in Texas, 1980.

Two surveillance systems were initiated in Texas in 1980 to detect cases of dengue fever. Physicians throughout the state were requested to report cases of dengue (passive surveillance), and 27 out-patient facilities serving geographically and ethnically high risk populations were asked to report cases of dengue-like illness weekly (active surveillance). Additionally, two clinics participating in active surveillance submitted acute-phase blood specimens weekly for dengue virus isolation. Sixty-three cases of illness due to dengue type 1 infection (dates of onset 2 August-10 November) were documented by virus isolation or serologic testing; 52 of them (83%) occurred n countries adjacent to the Texas-Mexico border. Fifty-six patients (89%) were Hispanic; 46 (73%) were females. Twenty-seven patients (43%) had not traveled outside the U.S. before becoming ill. Since no clinically apparent outbreak of dengue was ever recognized by public health officials in Texas in 1980, the active surveillance system in other Gulf Coast states should be considered when the risk of introduction of dengue is considered high.

A continuing focus of Hansen's disease in Texas.

To describe epidemiologic and clinical characteristics of Hansen's disease cases in Texas, information was abstracted from records of 810 patients reported from 1973 through 1997. Annually, from 18 to 54 patients were reported. Average annual incidence rates ranged from 1.9 to 2.4 cases per million population. A majority of the patients were male (63%) and white (77%). More than half (53%) of the patients were born in the United States; a majority (83%) of the patients born in the United States were born in Texas. Most (76%) patients were diagnosed with multi-bacillary leprosy. Foreign-born patients were more likely to be younger at onset and have multi-bacillary disease compared with patients born in the United States. Within Texas, an endemic focus of Hansen's disease exists along the Gulf of Mexico coast.

Parasites of waterfowl, from southwest Texas: III. The green-winged teal, Anas crecca.

Seventy of 72 green-winged teal, Anas crecca, from southwest Texas were infected with parasites. Seventeen species of endoparasites were recorded: Notocotylus attenuatus, Zygocotyle lunata, Typhlocoelum sisowi, Echinostoma revolutum, Hypoderaeum conoideum, Dendritobilharzia pulverulenta, Cloacotaenia megalops, Sobolevicanthus gracilis, Sobolevicanthus krabbeella, Gastrotaenia cygni, Amidostomum acutum, Amidostomum anseris, Tetrameres crami, Echinuria uncinata, Corynosoma constrictum, Polymorphus minutus. Also recorded were five species of ectoparasites: Trinoton querquedulae, Anaticola crassicornis, Anatoecous icterodes, Holomenopon setigerum and Epidermoptes sp. and the sacrosporidian, Sarcocystis rileyi. Anatoecous icterodes is a new host record for A. crecca. Sobolevicanthus gracilis, S. krabbeella, T. sisowi, and D. pulverulenta are new records for A. crecca in North America. Sobolevicanthus krabbeella is also a new record for North America. Fall juveniles had greater mean parasite intensity (29) than fall (19) and spring adults (19). Juveniles were infected with fewer species of parasites (17) than adults (20). Simpson's index was very low (0.11) indicating a diverse parasite fauna. Sorenson's index of similarity indicated that the parasite fauna for green-winged teal from southwest Texas was more similar to the shoveler's, Anas clypeata, parasites reported from southwest Texas (55%) than to green-winged teal parasites reported from eastern Canada (41%) and New Brunswick, Canada (21%).
