Survey of safety climate in public hospitals in Costa Rica in 1997

In response to growing concern for occupational health and safety in the public hospital system in Costa Rica, a research program was initiated in 1995 to evaluate and improve the safety climate in the national healthcare system through regional training programs, and to develop the capacity of the occupational health commissions in these settings to improve the identification and mitigation of workplace risks. A cross-sectional survey of 1000 hospital-based healthcare workers was conducted in 1997 to collect baseline data that will be used to develop appropriate worker training programs in occupational health. The objectives of this survey were to: (1) describe the safety climate within the national hospital system, (2) identify factors associated with safety climate focusing on individual and organizational variables, and (3) to evaluate the relationship between safety climate and workplace injuries and safety practices of employees. Individual factors evaluated included the demographic variables of age, gender, education and profession. Organizational factors evaluated included training, psychosocial work environment, job-task demands, availability of protective equipment and administrative controls. Work-related injuries and safety practices of employees included the type and frequency of injuries experienced and reported, and compliance with established safety practices. Multivariate regression analyses demonstrated that training and administrative controls were the two most significant predictors of safety climate. None of the demographic variables were significant predictors of safety climate. Safety climate was inversely and significantly associated with workplace injuries and positively and significantly associated with safety practices. These results suggest that training and administrative controls should be included in future training efforts and that improving safety climate will decrease workplace injuries and increase safety practices. ^

Relationship between enterotoxigenic Escherichia coli and travelers' diarrhea in Mexico, from 1992 to 1997

The purpose of this study was to examine the relationship between enterotoxigenic ETEC and travelers' diarrhea over a period of five years in Guadalajara, Mexico. Specifically, this study identified and characterized ETEC from travelers with diarrhea. The objectives were to study the colonization factor antigens, toxins and antibiotic sensitivity patterns in ETEC from 1992 to 1997 and to study the molecular epidemiology of ETEC by plasmid content and DNA restriction fragment patterns. ^ In this survey of travelers' diarrhea in Guadalajara, Mexico, 928 travelers with diarrhea were screened for enteric pathogens between 1992 and 1997. ETEC were isolated in 195 (19.9%) of the patients, representing the most frequent enteric pathogen identified. ^ A total of 31 antimicrobial susceptibility patterns were identified among ETEC isolates over the five-year period. ^ The 195 ETEC isolates contained two to six plasmids each, which ranged in size from 2.0 to 23 kbp. ^ Three different reproducible rRNA gene restriction patterns (ribotypes R-1 to R-3) were obtained among the 195 isolates with the enzyme, HindIII. ^ Colonization factor antigens (CFAs) were identified in 99 (51%) of the 195 ETEC strains studied. ^ Cluster analysis of the observations seen in the four assays all confirmed the five distinct groups of study-year strains of ETEC. Each group had a >95% similarity level of strains within the group and <60% similarity level between the groups. In addition, discriminant analysis of assay variables used in predicting the ETEC strains, reveal a >80% relationship between both the plasmid and rRNA content of ETEC strains and study-year. ^ These findings, based on laboratory observations of the differences in biochemical, antimicrobial susceptibility, plasmid and ribotype content, suggest complex epidemiology for ETEC strains in a population with travelers' diarrhea. The findings of this study may have implications for our understanding of the epidemiology, transmission, treatment, control and prevention of the disease. It has been suggested that an ETEC vaccine for humans should contain the most prevalent CFAs. Therefore, it is important to know the prevalence of these factors in ETEC in various geographical areas. ^ CFAs described in this dissertation may be used in different epidemiological studies in which the prevalence of CFAs and other properties on ETEC will be evaluated. Furthermore, in spite of an intense search in near 200 ETEC isolates for strains that may have clonal relationship, we failed to identify such strains. However, further studies are in progress to construct suitable live vaccine strains and to introduce several of CFAs in the same host organism by recombinant DNA techniques (Dr. Ann-Mari Svennerholm's lab).

Cutaneous malignant melanoma: A study of skin cancer in the United States from 1973--1997

Cutaneous malignant melanoma (CMM) is the cancer of the melanocytes, the cells that produce the pigment melanin, and is an aggressive skin cancer that is most prevalent in the white population. Although most cases of malignant melanoma are white, black and other non-white populations also develop this disease. However, the etiologic factors involved in the development of melanoma in these lower-risk populations are not well known. Generally, survival rates of malignant melanoma have been found to be lower in blacks than for whites with similar stage of disease at diagnosis. ^ This study presents an analysis of the differences in survival between black and white cases with malignant melanoma of the skin as the only or first primary cancer, found in the National Cancer Institute Surveillance, Epidemiology and End Results (SEER) cancer registry from 1973 to 1997. A total of 54,193 cases of CMM were diagnosed in black and white patients between 1973 and 1997. Black patients tended to be older, with a mean age of 64.46 years, compared to 53.14 years for white patients. Eighty-nine percent of patients were diagnosed with CMM as the only cancer.

Access to health care among children in the U.S.: Use of health inequalities measures to evaluate progress in reduction of disparities from 1997 to 2005

Much of the literature on disparities in access to health care among children has focused on measuring absolute and relative differences experienced by race/ethnic groups and, to a lesser extent, socioeconomic groups. However, it is not clear from existing literature how disparities in access to care may have changed over time for children, especially following implementation of the State Children’s Health Insurance Program (SCHIP). The primary objective of this research was to determine if there has been a decrease in disparities in access to care for children across two socioeconomic groups and race/ethnicity groups after SCHIP implementation. Methods commonly used to measure ‘health inequalities’ were used to measure disparities in access to care including population-attributable risk (PAR) and the relative index of inequality (RII). Using these measures there is evidence of a substantial decrease in socioeconomic disparities in health insurance coverage and to a lesser extent in having a usual source of care since the SCHIP program began. There is also evidence of a considerable decrease in non-Hispanic Black disparities in access to care. However, there appears to be a slight increase in disparities in access to care among Hispanic compared to non-Hispanic White children. While there were great improvements in disparities in access to care with the introduction of the SCHIP program, continuing progress in disparities may depend on continuation of the SCHIP program or similar targeted health policy programs. ^

Changing Tides and Changing Focus: Mapping the Challenges and Successes of One State's Implementation Of the Adoption and Safe Families Act of 1997

In 1997, the Adoption and Safe Families Act shifted from the preservation of families to an emphasis on safety, permanency, and well-being through expediting the termination of parental rights, establishing exceptions to the reasonable efforts clause of preserving the family, and fiscal incentives for finalizing adoptions. The current project assessed the role of a full service array in achieving the outcomes set forth in ASF A. Concept mapping was utilized to elicit information from participants (both urban and rural) regarding the identified research question. Participants recognized family preservation versus safety, community connections, mandates versus reality, and worker recruitment and retention as critical components for meeting ASFA goals. Perceived importance and level of success in implementing these services was also highlighted. Recommendations supported through the data are also provided.

First -year mortality and survival among infants with selected congenital anomalies in Texas, 1995 to 1997

Congenital anomalies have been a leading cause of infant mortality for the past twenty years in the United States. Few registry-based studies have investigated the mortality experience of infants with congenital anomalies. Therefore, a registry-based mortality study was conducted of 2776 infants from the Texas Birth Defects Registry who were born January 1, 1995 to December 31, 1997, with selected congenital anomalies. Infants were matched to linked birth-infant death files from the Texas Department of Health, Bureau of Vital Statistics. One year Kaplan-Meier survival curves, and mortality estimates were generated for each of the 23 anomalies by maternal race/ethnicity, infant sex, birth weight, gestational age, number of life-threatening anomalies, prenatal diagnosis, hospital of birth and other variables. ^ There were 523 deaths within the first year of life (mortality rate = 191.0 per 1,000 infants). Infants with gastroschisis, trisomy 21, and cleft lip ± palate had the highest first year survival (92.91%, 92.32%, and 87.59%, respectively). Anomalies with the lowest survival were anencephaly (5.13%), trisomy 13 (7.41%), and trisomy 18 (10.29%). ^ Infants born to White, Non-Hispanic women had the highest first year survival (83.57%; 95% CI: 80.91, 85.88), followed by African-Americans (82.43%; 95% CI: 76.98, 86.70) and Hispanics (79.28%; 95% CI: 77.19, 81.21). Infants with birth weights ≥2500 grams and gestational ages ≥37 weeks also had the highest first year survival. First year mortality drastically increased as the number of life-threatening anomalies increased. Mortality was also higher for infants with anomalies that were prenatally diagnosed. Slight differences existed in survival based on infant's place of delivery. ^ In logistic regression analysis, birth weight (<1500 grams: OR = 7.48; 95% CI: 5.42, 10.33; 1500–2499 grams: OR = 3.48; 95% CI: 2.74, 4.42), prenatal diagnosis (OR = 1.92; 95% CI: 1.43, 2.58) and number of life-threatening anomalies (≥3: OR = 22.45; 95% CI: 11.67, 43.18) were the strongest predictors of death within the first year of life for all infants with selected congenital anomalies. To achieve further reduction in the infant mortality rate in the United States, additional research is needed to identify ways to reduce mortality among infants with congenital anomalies. ^

Human complement component C3 -binding proteins of Mycobacterium tuberculosis

Mycobacterium tuberculosis, the causative agent of tuberculosis, is a facultative intracellular pathogen that uses the host mononuclear phagocyte as a niche for survival and replication during infection. Complement component C3 has previously been shown to enhance the binding of M. tuberculosis to mononuclear phagocytes. Using a C3 ligand affinity blot protocol, we identified a 30 kDa C3-binding protein in M. tuberculosis as heparin-binding hemagglutinin (HbhA). HbhA was found to be a hydrophobic protein that localized to the cell membrane/cell wall fraction of M. tuberculosis, and this protein has previously been shown by others to be located on the surface of M. tuberculosis. The C3-binding activity of HbhA was localized to the C-terminus of the protein, which consists of lysine-alanine repeats. Full-length recombinant HbhA coated onto latex beads was shown to mediate the adherence of the beads to murine macrophage-like cells in both a C3-dependent and a C3-independent manner. An in-frame 576 by deletion in the hbhA gene was created in a virulent strain of M. tuberculosis using a PCR technique known as gene splicing by overlap extension (SOEing). Using the ΔhbhA mutant, HbhA was found not to be necessary for growth of M. tuberculosis in laboratory media or in macrophage-like cells, nor is HbhA required for adherence of M. tuberculosis to macrophage-like cells. HbhA is, however, required for infectivity of M. tuberculosis in mice. Mice infected with the ΔhbhA mutant show decreased growth in the lungs, liver, and spleen compared to mice infected with the wild-type strain. Using the ΔhbhA mutant strain, we were able to purify and identify a second 30-kDa C3-binding protein, HupB. These data demonstrate that HbhA is required for the in vivo but not the in vitro survival of M. tuberculosis and that HbhA is not necessary for the adherence of M. tuberculosis to the macrophage-like cells used in these studies. The expression of two proteins that bind human C3 may aid in the efficient binding of M. tuberculosis to complement receptors for uptake into mononuclear cells, or may influence other aspects of the host-parasite interaction. ^
