An evaluation of the impact of Inner City Development's Cooperative Home School: An educational alternative program to increase the quality and level of education in San Antonio's West Side community

The research study was intended to evaluate the effectiveness of Inner City Development's (I.C.D.) Cooperative Home School, an educational alternative program to the Title I public schools of San Antonio's West Side community. The study investigated students', parents' and tutors' perception of parental involvement and educational resources. The study also investigated each student's academic achievement. ^ The study found that students progressed toward expected math proficiency at a faster rate than they did in reading proficiency. However, because the target population size was small and a comparison group was not used, the results of this study are only suggestive. This research also indicated that study subjects believed students' quality and level of education increased substantially since program exposure. Study subjects mainly attributed the students' strides in academic performance to the increased amount of individualized attention students received in the small twelve-student class size. Study subjects were more satisfied with the home school's educational resources than those of the Title I public schools. Study subjects also perceived that parental involvement both at home and at school increased since enrollment in the home school program because: (1) there were more opportunities for involvement in the home school; and (2) parents felt closer to the tutors than the teachers in public school. ^ This evaluation also suggested improvements to program operations. With the help of additional volunteers, I.C.D. program operators could improve collection and organization of academic records. Furthermore, as suggested by program participants, science could be added to the curriculum. Lastly, a formal tutor orientation could be implemented to familiarize and train tutors on classroom management procedures. ^

Better together: Addressing maternal and child health outcomes through community health worker continuing education curricula

Background. The incidence of birth defects is a significant public health issue in the United States, adversely affecting the quality of life for parents as well as children born with these defects. Minority populations face a greater burden of birth defects and associated health problems. Prenatal practices can have a large impact on infant health outcomes. Several behaviors during pregnancy, including the intake of folic acid, can greatly influence the likelihood of a child being born with a birth defect. Community Health Workers have been shown to be effective agents at improving prenatal practices, especially when they facilitate support groups that feature pregnant women. ^ Methods. A continuing education curriculum has been created for Community Health Workers that provides content in the area of Maternal and Child Health. Content was selected after conducting a review of relevant literature and theory. Materials for conducting a training for Community Health Workers have been created in addition to materials that were designed for the population with whom the CHWs work. ^ Results. A description of each "key point" of the curriculum and a justification how it relates to the literature of the prevention of birth defects is given here. Additionally, the process of creating the curriculum using the platform delineated in the methods is described. ^ Discussion. Insights for future curriculum development are discussed along with next steps in the process of certifying the curriculum at the state level. A framework for future evaluation of the curriculum is given.^

Determining the feasibility and acceptability of a garden-based nutrition curriculum for preschoolers

Obesity rates around the nation have risen to epidemic proportions. Rates of childhood obesity are at very high levels with 24.4% of preschool-aged children in the U.S. currently considered as overweight or obese. The percentage of childhood obesity is much higher in the southern part of the United States as compared to the rest of the nation. Minority populations, especially African American and Hispanic, are affected more than other ethnic groups. Obesity prevention programs are needed targeting young children <6 years of age from minority populations. Currently, there are few obesity prevention programs that have been implemented and evaluated in children <6 years of age. Gardening programs have been successful in improving the health status of elementary school children by increasing fruit and vegetable intake and increasing preferences for healthier food choices. However, there is no evidence of the feasibility and acceptability of a garden-based obesity prevention program among preschoolers. This pretest study, a classroom-based gardening curriculum program with 16 lesson plans and coordinating activities for preschool age children (3-5 years old) enrolled in Head Start, provides the opportunity to address this need. The study included 103 preschoolers from two centers and 9 teachers or teachers' aides. Qualitative data on feasibility and acceptability was collected from process evaluation forms of individual lesson plans and focus groups with teachers. Teacher questionnaires assessed individual teacher characteristics and provided feedback regarding the curriculum. Quantitative measures of teachers' self-efficacy, attitudes, and knowledge pertaining to nutrition were analyzed from pre and post-test surveys. Results revealed this preschool garden-based nutrition curriculum was both feasible and acceptable. The program improved teacher's self-efficacy, knowledge, and attitudes about nutrition, with teacher's confidence in ability to teach a gardening curriculum increasing from a mean score of 2.14 to 3.00 from pre to post test (P value = 0.0046). These results indicate implementing garden-based nutrition lessons within preschools is achievable. Employing garden-based nutrition lessons in the classroom is the first step in teaching children about nutrition and gardening concepts. Constructing gardening beds for more hands-on learning is the next proposed step in the larger parent study of this program.^

A History of Organized Medicine in Harris County, Texas

The item was written by the Historical Committee of the Harris County Medical Society and signed on October 28, 1948. A brief history of medicine in Texas is given before the focus shifts to the Harris County and Houston area. Information on the early years is taken from various sources such as Pat Ireland Nixon’s The Medical Story of Early Texas and the writings of George Plunkett (Mrs. S. C.) Red. Significant information comes from the Minutes of the Harris County Medical Society.

Primary lung cancer after breast cancer: The role of radiation therapy and cigarette smoking

The magnitude of the interaction between cigarette smoking, radiation therapy, and primary lung cancer after breast cancer remains unresolved. This case control study further examines the main and joint effects of cigarette smoking and radiation therapy (XRT) among breast cancer patients who subsequently developed primary lung cancer, at The University of Texas M. D. Anderson Cancer Center (MDACC) in Houston, Texas. Cases (n = 280) were women diagnosed with primary lung cancer between 1955 and 1970, between 30–89 years of age, who had a prior history of breast cancer, and were U.S. residents. Controls (n = 300) were randomly selected from 37,000 breast cancer patients at MDACC and frequency matched to cases on age at diagnosis (in 5-year strata), ethnicity, year of breast cancer diagnosis (in 5-year strata), and had survived at least as long as the time interval for lung cancer diagnosis in the cases. Stratified analysis and unconditional logistic regression modeling were used to calculate the main and joint effects of cigarette smoking and radiation treatment on lung cancer risk. Medical record review yielded smoking information on 93% of cases and 84% of controls, and among cases 45% received XRT versus 44% of controls. Smoking increased the odds of lung cancer in women who did not receive XRT (OR = 6.0, 95%CI, 3.5–10.1) whereas XRT was not associated with increased odds (OR = 0.5, 95%CI, 0.2–1.1) in women who did not smoke. Overall the odds ratio for both XRT and smoking together compared with neither exposure was 9.00 (9 5% CI, 5.1–15.9). Similarly, when stratifying on laterality of the lung cancer in relation to the breast cancer, and when the time interval between breast and lung cancers was >10 years, there was an increased odds for both smoking and XRT together for lung cancers on the same side as the breast cancer (ipsilateral) (OR = 11.5, 95% CI, 4.9–27.8) and lung cancers on the opposite side of the breast cancer (contralateral) (OR= 9.6, 95% CI, 2.9–0.9). After 20 years the odds for the ipsilateral lung were even more pronounced (OR = 19.2, 95% CI, 4.2–88.4) compared to the contralateral lung (OR = 2.6, 95% CI, 0.2–2.1). In conclusion, smoking was a significant independent risk factor for lung cancer after breast cancer. Moreover, a greater than multiplicative effect was observed with smoking and XRT combined being especially evident after 10 years for both the ipsilateral and contralateral lung and after 20 years for the ipsilateral lung. ^

A case comparison study of dietary factors and risk of colorectal polyps

Little is known about the etiology of colorectal adenomatous polyps, although they are generally considered to be precursor lesions to colorectal carcinoma. To investigate the associations of colorectal adenomatous polyps with dietary intake of calcium, total fat and fiber, a case comparison study was conducted among 98 persons who had first occurrences of adenomatous polyps and 408 persons who did not have colorectal polyps.^ The study population comprised Black, White and Hispanic males and females ages 35 to 80 inclusive, who underwent a sigmoidoscopy or total colonoscopy at collaborating clinics in the Texas Medical Center at Houston between September 1991 and November 1992, and met the eligibility criteria. Case participants were those who had a first-time diagnosis of adenomatous polyps. Comparison participants were individuals who underwent the same diagnostic procedure as the cases and met the same eligibility criteria but had no colorectal polyps. A food frequency questionnaire was administered by interview to obtain information about diet during the 28 days preceding the interview.^ Dietary intake of total fiber was inversely associated with risk of adenomatous polyps. An increment of 15 gm/day in energy-adjusted intake of fiber was associated with a relative odds of 0.39 with a 95% confidence interval of 0.20 to 0.79, after adjustment for age, sex, ethnicity, body mass index, cigarette smoking, family history of colorectal cancer and intake of nonsteroidal anti-inflammatory drugs. No association between dietary intake of total fat and risk of adenomatous polyps was observed. When total fat was analyzed as percent of energy, an increment of 15.3% in intake was associated with a relative odds of 0.98 with a 95% confidence interval of 0.53 to 1.80. However, few persons in the study group had intakes below 25% of energy from total fat. An inverse association was observed between energy-adjusted intake of dietary calcium and risk of adenomatous polyps, but this was not statistically significant; an increment of 638 mg/day was associated with a relative odds of 0.77 with a 95% confidence interval of 0.41 to 1.38. Intake of calcium did not appear to strongly modify the association between intake of fat and risk of adenomatous polyps, perhaps because the study group included few people with calcium intake below 400 mg/day.^ These results support the idea that dietary fiber decreases risk of adenomatous polyps. Further studies are needed on the association of dietary calcium and fat with risk of colorectal adenomatous polyps in populations where individuals vary widely in intake of these nutrients. ^
