Based on the success of a community health and wellness program, Wellness in the City, delivered in Dallas County by trained volunteers, Texas Cooperative Extension (TCE) decided to pilot the program in 16 counties in North and East Texas. Before implementing the program, TCE wanted the Dallas County program to be reviewed and revised as needed to meet the diverse community needs in the pilot counties. TCE also asked for an implementation manual to be developed for the county agents to utilize. ^ To achieve these objectives, I first reviewed literature on other volunteer-implemented health interventions in the U.S. to see how they were planned, disseminated, implemented, and evaluated. Next, I reviewed the Wellness in the City program and materials. I applied all the information I gathered up to that point to the program development committee meetings (committee included seven TCE county agents, a TCE regional program director, and me). The program structure and training materials were revised based on our research and program implementation experience. These changes were made to ensure adequate training for the volunteers and to create a program that is applicable in the communities it will be piloted in. ^ With the program structure and training presentations developed, next I focused on compiling the implementation manual, which includes program details and volunteer recruitment, training, and management materials. The goal was to create a manual with everything the county agents will need to implement the program, so they can focus their efforts on putting the manual to use and recruiting and managing the volunteers. The final step was developing a program evaluation form for the agents to complete. It includes questions to assess the agents' thoughts about the training content, the feasibility of implementing the program using the manual, and the challenges of the program. ^

The clinical records of 432 P. falciparum and P. vivax infected volunteer male inmates of the Maryland House of Corrections in Jessup, Maryland, were studied to determine (1) the clinical and parasitologic courses of infections in both parasite species, and (2) the influence of previous homologous and/or heterologous strain exposures on subsequent infections. The clinical and parasitologic courses of infection with both P. falciparum and P. vivax species indicated that: (a) there were characteristic strain related differences between P. falciparum and P. vivax. P. falciparum strains were more apt to cause severe infections than P. vivax strains. (b) Blood-induced infections produced significantly shorter prepatent and incubation periods than mosquito-induced. (c) Blacks tolerated the infections better than whites and, (d) homologous and heterologous strain immunities persisted with previous malaria history. In previously exposed cases, clinical manifestations were moderate, peak fever lowered, and peak parasitemias limited. (e) Anti-malarial drugs were effective in reducing sexual and asexual forms of the malaria parasite, and limiting peak fevers, irrespective of method of induction, race, parasite strain and species, and drug type used.^ Given these findings, and the current worldwide resurgence of malaria, this study has major implications in terms of setting malaria control and public health policies in both developed and developing countries.^

The hyl(Efm) gene (encoding a putative hyaluronidase) has been found almost exclusively in Enterococcus faecium clinical isolates, and recently, it was shown to be on a plasmid which increased the ability of E. faecium strains to colonize the gastrointestinal tract. In this work, the results of mating experiments between hyl(Efm)-containing strains of E. faecium belonging to clonal cluster 17 and isolated in the United States and Colombia indicated that the hyl(Efm) gene of these strains is also carried on large plasmids (>145 kb) which we showed transfer readily from clinical strains to E. faecium hosts. Cotransfer of resistance to vancomycin and high-level resistance (HLR) to aminoglycosides (gentamicin and streptomycin) and erythromycin was also observed. The vanA gene cluster and gentamicin resistance determinants were genetically linked to hyl(Efm), whereas erm(B) and ant(6)-I, conferring macrolide-lincosamide-streptogramin B resistance and HLR to streptomycin, respectively, were not. A hyl(Efm)-positive transconjugant resulting from a mating between a well-characterized endocarditis strain [TX0016 (DO)] and a derivative of a fecal strain of E. faecium from a healthy human volunteer (TX1330RF) exhibited increased virulence in a mouse peritonitis model. These results indicate that E. faecium strains use a strategy which involves the recruitment into the same genetic unit of antibiotic resistance genes and determinants that increase the ability to produce disease. Our findings indicate that the acquisition of the hyl(Efm) plasmids may explain, at least in part, the recent successful emergence of some E. faecium strains as nosocomial pathogens.

A worksite health education program called “Your Heart Can't Wait,” was designed by the American Heart Association Gulf Coast Area (AHA). The objectives were to educate individuals about the signs and symptoms of heart attacks and the actions they should take to improve heart attack victims' chances for survival. AHA volunteers agreed to serve as mentors for this program. ^ A study was designed to determine if worksite coordinators who had the assistance of experienced AHA volunteers had higher rates of program adoption and implementation than worksite coordinators without assistance. Ninety-seven companies participated in the study. Twelve AHA volunteers were randomly assigned to work with forty-three of the worksite coordinators. Mentor/mentee contact forms were used to assess the mentoring process during the course of the study. Program adoption forms were used to measure rates of program adoption and follow-up questionnaires were used to measure rates of program implementation after the study was completed. The twelve mentors were interviewed to provide information for improving future mentoring efforts. ^ Thirty-eight companies completed program adoption forms and fifty-one companies reported using YHCW program components. For the most part, the volunteer mentors did not spend a significant amount of time contacting or working with their assigned worksite coordinators. As a result, the planned analysis comparing the implemented programs between worksite coordinators with and without assistance could not be completed. ^ Additional analyses were performed comparing the implemented programs based upon whether the companies had existing health education/health promotion programs and whether the worksite coordinators had experience using AHA Heart At Work program components. ^ Recommendations based on the mentor interviews were made to improve the success of volunteer assistance programs in the future. ^

Enteroaggregative Escherichia coli (EAEC) are considered an important emerging enteric and food-borne pathogen. The groups importantly affected by EAEC include international travelers, children in the developing world, and patients with HIV infection. EAEC does not commonly cause diarrheal illness in all hosts. ^ The reasons for the observed clinical variation in EAEC infection are multifactorial and are dependant on the pathogen, the inoculum ingested and the host susceptibility. A major obstacle in identifying the mechanism of pathogenesis for EAEC is the heterogeneity in virulence of strains. No EAEC virulence gene is consistently present in all diarrheagenic strains. However, a recent report suggests that a package of plasmid borne and chromosomal virulence factors are under the control of the described transcriptional activator aggR. Although the exact inoculum required for EAEC diarrheal illness is not known, a volunteer study has shown that oral ingestion of 10 10 cfu of virulent EAEC elicited diarrhea. Ongoing studies are being conducted to better define the exact infectious dose. There are also host factors associated with increased susceptibility of persons to diarrheal illness with EAEC. ^ The following three manuscripts: (1) review EAEC as an emerging enteric pathogen; (2) identify EAEC as a cause of acute diarrhea among different subpopulations worldwide; (3) identify virulence characteristics and the molecular epidemiology of EAEC isolates among travelers with diarrheal illness and describe the pathogenesis of EAEC infection. ^

The purpose of this study was to conduct a descriptive, exploratory analysis of the utilization of both traditional healing methods and western biomedical approaches to health care among members of the Vietnamese community in Houston, Texas. The first goal of the study was to identify the type(s) of health care that the Vietnamese use. The second goal was to highlight the numerous factors that may influence why certain health care choices are made. The third goal of this study was to examine the issue of preference to determine which practices would be used if limiting factors did not exist. ^ There were 81 participants, consisting of males and females who were 18 years or older. The core groups of participants were Vietnamese students from the University of Houston-Downtown and volunteer staff members from VN TeamWork. Asking the students and staff members to recommend others for the study used the snowball method of recruiting additional participants. ^ Surveys and informed consents were in English and Vietnamese. The participants were given the choice to take the surveys face-to-face or on their own. Surveys consisted of structured questions with predetermined choices, as well as, open-ended questions to allow more detailed information. The quantitative and qualitative data were coded and entered into a database, using SPSS software version 15.0. ^ Results indicated that participants used both traditional (38.3%) and biomedical (59.3%) healing, with 44.4% stating that it depended on the illness as to treatment. Coining was the most used traditional healing method, clearly still used by all ages. Coining was also the method most used when issues regarding fear and delayed western medical treatment were involved. It was determined that insurance status, more than household income, guided health care choices. A person's age, number of years spent in the United States, age at migration, and the use of certain traditional healing methods like coining all played a role in the importance of the health care practitioner speaking Vietnamese. The most important finding was that 64.2% of the participants preferred both traditional and western medicine because both methods work. ^

The Houston region is home to arguably the largest petrochemical and refining complex anywhere. The effluent of this complex includes many potentially hazardous compounds. Study of some of these compounds has led to recognition that a number of known and probable carcinogens are at elevated levels in ambient air. Two of these, benzene and 1,3-butadiene, have been found in concentrations which may pose health risk for residents of Houston.^ Recent popular journalism and publications by local research institutions has increased the interest of the public in Houston's air quality. Much of the literature has been critical of local regulatory agencies' oversight of industrial pollution. A number of citizens in the region have begun to volunteer with air quality advocacy groups in the testing of community air. Inexpensive methods exist for monitoring of ozone, particulate matter and airborne toxic ambient concentrations. This study is an evaluation of a technique that has been successfully applied to airborne toxics.^ This technique, solid phase microextraction (SPME), has been used to measure airborne volatile organic hydrocarbons at community-level concentrations. It is has yielded accurate and rapid concentration estimates at a relatively low cost per sample. Examples of its application to measurement of airborne benzene exist in the literature. None have been found for airborne 1,3-butadiene. These compounds were selected for an evaluation of SPME as a community-deployed technique, to replicate previous application to benzene, to expand application to 1,3-butadiene and due to the salience of these compounds in this community. ^ This study demonstrates that SPME is a useful technique for quantification of 1,3-butadiene at concentrations observed in Houston. Laboratory background levels precluded recommendation of the technique for benzene. One type of SPME fiber, 85 μm Carboxen/PDMS, was found to be a sensitive sampling device for 1,3-butadiene under temperature and humidity conditions common in Houston. This study indicates that these variables affect instrument response. This suggests the necessity of calibration within specific conditions of these variables. While deployment of this technique was less expensive than other methods of quantification of 1,3-butadiene, the complexity of calibration may exclude an SPME method from broad deployment by community groups.^

Background. In public health preparedness, disaster preparedness refers to the strategic planning of responses to all types of disasters. Preparation and training for disaster response can be conducted using different teaching modalities, ranging from discussion-based programs such as seminars, drills and tabletop exercises to more complex operation-based programs such as functional exercises and full-scale exercises. Each method of instruction has its advantages and disadvantages. Tabletop exercises are facilitated discussions designed to evaluate programs, policies, and procedures; they are usually conducted in a classroom, often with tabletop props (e.g. models, maps or diagrams). ^ Objective. The overall goal of this project was to determine whether tabletop exercises are effective teaching modalities for disaster preparedness, with an emphasis on intentional chemical exposure. ^ Method. The target audience for the exercise was the Medical Reserve Brigade of the Texas State Guard, a group of volunteer healthcare providers and first responders who prepare for response to local disasters. A new tabletop exercise was designed to provide information on the complex, interrelated organizations within the national disaster preparedness program that this group would interact with in the event of a local disaster. This educational intervention consisted of a four hour multipart program that included a pretest of knowledge, lecture series, an interactive group discussion using a mock disaster scenario, a posttest of knowledge, and a course evaluation. ^ Results. Approximately 40 volunteers attended the intervention session; roughly half (n=21) had previously participated in a full scale drill. There was an 11% improvement in fund of knowledge between the pre- and post-test scores (p=0.002). Overall, the tabletop exercise was well received by those with and without prior training, with no significant differences found between these two groups in terms of relevance and appropriateness of content. However, the separate components of the tabletop exercise were variably effective, as gauged by written text comments on the questionnaire. ^ Conclusions. Tabletop exercises can be a useful training modality in disaster preparedness, as evidenced by improvement in knowledge and qualitative feedback on its value. Future offerings could incorporate recordings of participant responses during the drill, so that better feedback can be provided to them. Additional research should be conducted, using the same or similar design, in different populations that are stakeholders in disaster preparedness, so that the generalizability of these findings can be determined.^

Purpose: To examine the effect of obesity and gestational weight gain on heart rate variability (HRV), oxygenation (HbO 2 and SpO2), hemoglobin A1c (HbA1c) and the frequency of pregnancy complications in obese (O) and non-obese (NO) women.^ Design: The study was an observational comparison study with a repeated measures design. ^ Setting: The setting was a low risk prenatal, university clinic located in a large southeastern metropolitan city. ^ Sample: The sample consisted of a volunteer group of 41 pregnant women who were observed at the three time points of 20, 28, and 36 weeks gestation. ^ Analysis: Analysis included general linear modeling with repeated measures to test for group differences with changes over time on vagal response, HbA1c, and oxygenation. Odds ratios were computed to compare the frequency of birth outcomes. ^ Findings: The interaction effect of time between O and NO women on HbO2 was significant. The mean HP, RSA, and HbO2 changed significantly over time within the NO women. The mean HbA 1c increased significantly over time within the O women. Women with excess gestational weight gain had significantly lower heart period than women with weight gain within the IOM recommendations. Obese women were more likely to have Group B streptococcal infections, gestational hypertension, give birth by cesarean or instrument assistance, and have at least one postnatal event. ^ Conclusions: Monitoring HRV, oxygenation, and HbA1c using minimally invasive measures may permit early identification of alterations in autonomic response. Implementation of interventions to promote vagal tone may help to reduce risks for adverse perinatal outcomes related to obesity. Future studies should examine the effect of obesity on the vagal response and perinatal outcomes. ^

This study was an exploratory investigation of variables which are associated with neonatal intensive care nurses' perceptions of and participation in life-sustaining treatment decisions for critically ill newborns. The primary purpose of the research was to examine the extent to which assessment of infants' physical and mental prognoses, parents' preferences regarding treatment, and legal consequences of non-treatment influence nurses' recommendations about life-saving treatment decisions for handicapped newborns. Secondly, the research explored the extent and nature of nurses' reported participation in the resolution of treatment dilemmas for these critically ill newborns. The framework of the study draws upon the work of Crane (1977), Blum (1980), and Pearlman (1982) who have explored the sociological context of decision-making with critical care patients.^ Participants in the study were a volunteer sample of eighty-three registered nurses who were currently working in neonatal intensive care units in five large urban hospitals in Texas. Data were collected through the use of intensive interviews and case study questionnaires. Results from the study indicate that physical and mental prognoses as well as parent preferences and concerns about legal liability are related to nurses' treatment recommendations, but their levels of significance vary according to the type of handicapping condition and whether the treatment questions are posed in terms of initiating aggressive therapy or withdrawing aggressive therapy.^ The majority of nurses reported that the extent of their participation in formal decision-making regarding handicapped newborns was fairly minimal although they provide much of the definitive data used to make decisions by physicians and parents. There was substantial evidence that nurse respondents perceive their primary role as advocates for critically ill newborns, and believe that their involvement in the resolution of treatment dilemmas should be increased. ^

In this study, an attempt is made to evaluate certain parameters that might indicate the beginning of a certain fibrogenic activity in the lung parenchyma, even before such changes become visible on the chest x-ray. The hypothesis is that studies such as certain bronchoalveolar immunological characteristics and Gallium-67 lung scans may be more sensitive indicators of parenchymal lung damage in response to asbestos inhalation than conventional radiographic criteria. If so, then in those cases where the criteria for the diagnosis of asbestosis lack the presence of parenchymal changes, it would be unwise to deny the diagnosis unless further investigations, such as the bronchoalveolar lavage fluid analysis and the Gallium-67 lung scan techniques, are made available.^ Four groups of individuals have been included in this study. The volunteer group showing no history of asbestos exposure with normal chest x-rays has been used as a normal healthy comparison group. The other three groups are all asbestos-exposed but differ as to their findings in the chest radiographs. One has parenchymal changes (0/1 or more, ILO Classification), the second has no parenchymal but pleural changes, and the third has neither.^ The most significant laboratory parameter for bronchoalveolar lavage, in this study, is that of Neutrophils (PMNs). All three asbestos-exposed groups showed no differences when compared with each other, while such differences were statistically significant when such groups were separately compared with the normal comparison group. A similar finding existed also when the Helper: Suppressor T-Cell ratios were compared, and found to be higher in all the asbestos-exposed groups.^ Another sensitive test is that of Gallium-67 lung scan. This was found to be positive in some patients where parenchymal changes were absent. Even in some of those who showed neither parenchymal nor pleural changes in their chest x-ray showed positive test results. Such changes indicate a state of an underlying pathogenic process that is still undetectable by conventional radiography. This highly recommends the future application of such tests for the early detection of active pulmonary disease, especially in those who show no parenchymal changes in their chest x-rays.

The purpose of this study was to identify the smoking prevalence among high school students in rural areas of Thailand and the factors associated with their smoking habits. The sample population was comprised of 946 volunteer students of both sexes enrolled in the twelfth grade classes of the 1981-82 school year in randomly chosen regional public high schools throughout the country. Data were obtained from a formal self-administered questionnaire survey. The comparisons were treated by classified smoking habits as "non-smoker," "trier," "ex-smoker," and "smoker."^ The study presented the low rate of cigarette smoking habits among female students, compared to male students. Significant differences of smoking-related habits were found among those who had exemplar models for smoking habits; fathers, siblings and peers were their reference groups. Parental approval was found to be a significant factor associated with students' smoking habits. The awareness of health hazards, the perceptions of the influence of cigarette advertisement, and the attitudes toward the concerns of government in cigarette manufacturing were also factors associated with cigarette smoking habits of high school subjects. ^

Volunteering is intricately woven into the fabric of our society. In 2009 alone, approximately 63.4 million Americans participated in volunteer activities, collectively donating over 8.1 billion service-hours (Corporation for National and Community Service [CNCS], 2010). Each service-hour is determined by the U.S. Bureau of Labor Statistics (2010) to be valued at $20.85/hr which translates to a national savings of $169 billion. Thus, we can clearly observe the significance of volunteer contribution to the overall benefit of society. In addition, there is now evidence that voluntary service may also benefit the actual volunteer, especially individuals who are 65+ years. As we reach 2020 this elderly class, composed of nearly 13 million (CNCS, 2010) Americans, will be of much consequence. Their potential to contribute in community-related efforts may save the U.S. billions in labor costs, and may also help reduce healthcare-related expenditures if volunteering proves to be a protective factor. In this literature review, we set out to explore the potential relationship between volunteer participation and increased mental and physical wellness. We also examined volunteer demographic characteristics and common motives for engaging in service-related activities. Analysis showed that volunteer work often combined low-impact physical activity and mental satisfaction from serving others, resulting in overall health benefit. Demographic characteristics displayed were consistent with previous studies and found that a majority of volunteers were female, White, married status, having received college degree or higher, employed, middle-high SES. In addition, age was seen to be a key characteristic in forecasting volunteer motivation and self-reported perceived health benefits.^

Community health workers (CHWs) can serve as a bridge between healthcare providers and communities to positively impact social determinants of health and, thus, the overall health of the population. The potential to effect lasting change is particularly significant within resource-poor settings with limited access to formally trained health care providers such as the small, rural village of Santa Ana Intibucá, Honduras and surrounding areas—located on the geographically and politically isolated border of Honduras and El Salvador. The Baylor Shoulder to Shoulder Foundation (BSTS) works in conjunction with Santa Ana's volunteer health committee to bring a health brigade that has provided health care and public health projects to the area at least twice a year since 2001. They have also hired a full-time Honduran physician, a Honduran in-country administrative director, and built a clinic; yet, no community health worker program exists. This CHW program model is the response to a clear need for a CHW program within the area served by BSTS and presents a CHW program model specific to Santa Ana Intibucá and surrounding areas to be implemented by BSTS. Methods used to develop this model include reviewing the literature for recommendations from leading authorities as well as successfully implemented CHW programs in comparable regions. This information was incorporated into existing knowledge and materials currently being used in the area. Using the CHW model proposed here, each brigade, in conjunction with the communities served, can help develop new modules to respond to the specific health priorities of the region at that time, incorporating consistent modes of contact with the local physician and the CHWs to provide refresher courses, training in new topics of interest, and to be reminded of the importance of community health workers' role as the critical link to healthy societies. With cooperation, effort, and support, the brigade can continue to help integrate a sustainable CHW system in which communities may be able to maximize the care they receive while also learning to care for their own health and the future of their communities.^
