RESUMO

The Appalachian region experiences higher incidence and mortality due to cervical cancer compared with other regions of the United States. The goal of the Ohio State University Center for Population Health and Health Disparities (CPHHD), called the Community Awareness Resources and Education (CARE) project, was to understand reasons for this disparity. The first wave (2003-2008) of funding included three projects focusing on the known risk factors for cervical cancer, lack of screening, smoking, and infection with human papillomavirus (HPV). On the basis of the results of these projects, the second wave (2011-2017) included four projects, designed to address a multi-level model of factors contributing to cervical disparities in Appalachia. The results of these projects were then used to refine a multi-level model that explains cervical cancer disparities in Appalachia. Future funded projects will take these multi-level explanations for cervical disparities and focus on implementation science strategies to reduce the burden of cervical cancer morbidity and mortality in Appalachia.See all articles in this Special Collection Honoring Paul F.

RESUMO

OBJECTIVE: To determine if patients' level of effort (LOE) in therapy sessions during traumatic brain injury (TBI) rehabilitation modifies the effect of compliance with the 3-Hour Rule of the Centers for Medicare & Medicaid Services. DESIGN: Propensity score methodology applied to the TBI Practice-Based Evidence database, consisting of multisite, prospective, longitudinal observational data. SETTING: Acute inpatient rehabilitation facilities (IRF). PARTICIPANTS: Patients (N=1820) who received their first IRF admission for TBI in the United States and were enrolled for 3- and 9-month follow-up. MAIN OUTCOME MEASURES: Participation Assessment with Recombined Tools-Objective-17, FIM Motor and Cognitive scores, Satisfaction with Life Scale, and Patient Health Questionnaire-9. RESULTS: When the full cohort was examined, no strong main effect of compliance with the 3-Hour Rule was identified and LOE did not modify the effect of compliance with the 3-Hour Rule. In contrast, LOE had a strong positive main effect on all outcomes, except depression. When the sample was stratified by level of disability, LOE modified the effect of compliance, particularly on the outcomes of participants with less severe disability. For these patients, providing 3 hours of therapy for 50% or more of therapy days in the context of low effort resulted in poorer performance on select outcome measures at discharge and up to 9 months postdischarge compared to patients with <50% of 3-hour therapy days. CONCLUSIONS: LOE is an active ingredient in inpatient TBI rehabilitation, while compliance with the 3-Hour Rule was not found to have a substantive effect on the outcomes. The results support matching time in therapy during acute TBI rehabilitation to patients' LOE in order to optimize long-term benefits on outcomes.

RESUMO

INTRODUCTION: The social-contextual model of tobacco control and the potential mechanisms of the maintenance or cessation of smoking behavior among disadvantaged women, including rural residents, have yet to be comprehensively studied. The purpose of this study was to determine the association between selected individual, interpersonal, workplace, and neighborhood characteristics and smoking status among women in Appalachia, a US region whose residents experience a disproportionate prevalence of tobacco-related health disparities. These findings may assist in efforts to design and test scientifically valid tobacco control interventions for this and other disadvantaged populations. METHODS: Women, 18 years of age and older, residing in three rural Ohio Appalachian counties, were recruited using a two-phase address-based sampling methodology for a cross-sectional interview-administered survey between August 2012 and October 2013 (N=408). Multinomial logistic regression was employed to determine associations between select multilevel factors (independent variables) and smoking status (dependent variable). The sample included 82 (20.1%) current smokers, 92 (22.5%) former smokers, and 234 (57.4%) women reporting never smoking (mean age 51.7 years). RESULTS: In the final multivariable multinomial logistic regression model, controlling for all other significant associations, constructs at multiple social-contextual levels were associated with current versus either former or never smoking. At the individual level, for every additional year in age, the odds of being a former or never smoker increased by 7% and 6% (odds ratio (OR) (95% confidence interval(CI)): 1.07 (1.0-1.11) and 1.06 (1.02-1.09)), respectively, as compared to the odds of being a current smoker. With regard to depression, for each one unit increase in the Center for Epidemiologic Studies Depression Scale score, the odds of being a former or never smoker were 5% and 7% lower (OR(95%CI): 0.95(0.91-0.999) and 0.93(0.88-0.98)), respectively. Five interpersonal factors were associated with smoking status. As the social influence injunctive norm score increased by one unit, indicating perception of smoking to be more acceptable, the odds of being a former or never smoker decreased by 23% and 30%, respectively. For every one unit increase in the social participation score, indicating past-year engagement in one additional activity type, the odds of being a former or never smoker increased by 17% and 36%, respectively. For every 10% increase in the percentage of social ties in the participant's advice network who smoked, the odds of being a former or never smoker were 24% and 28% less, respectively. For every 0.1 unit increase in the E/I index, indicating increasing homophily on smoking in one's social network, the odds of being a former or never smoker were 20% and 24% less, respectively, in the time network, and 18% and 20% less, respectively, in the advice network. At the neighborhood level, for every one unit increase in neighborhood cohesion score, indicating increasing cohesion, the odds of being a former smoker or never smoker were 12% and 14% less, respectively. CONCLUSIONS: These findings indicate that a social-contextual approach to tobacco control may be useful for narrowing a widening trajectory of smoking disparity for rural women. Interpersonal context, in particular, must be considered in the development of culturally targeted cessation interventions for Ohio Appalachian women.

RESUMO

PURPOSE: This article describes recruitment of a subpopulation of women in a rural area, extending an existing method of a 2-phase address-based sampling protocol to include a mixed-mode approach. METHODS: Phase 1 included a household enumeration questionnaire mailed to randomly selected households (n = 1,950) in 3 Ohio Appalachian counties to identify members of the eligible subgroup. The second phase of recruitment involved contacting 1 randomly selected eligible woman enumerated by each household, based on return of the questionnaire. These women (n = 599) were invited by field interviewers to participate in a one-time in-person health survey. FINDINGS: Of the women invited to participate, a total of 408 completed the interview. Based on American Association for Public Opinion Research Response Rate 1 calculations, the response rates were 44.4% and 70.3% for phases 1 and 2, respectively. Response rates in this study were encouraging, especially for the second phase in-person interview. CONCLUSION: We discuss implications for future research using a mixed-mode approach in this subpopulation.

RESUMO

PURPOSE: To examine how demographic, general health, religious, and political characteristics influenced beliefs about mandatory school vaccinations and history of vaccination refusal for children among Ohio Appalachian parents. METHODS: In 2013 and 2014, baseline data were obtained from parents (n = 337) of girls aged 9-17 from 12 counties in rural Ohio Appalachia enrolled in the Community Awareness, Resources and Education (CARE II) Project. Multivariate logistic regression models were used to identify correlates of parental beliefs about mandatory school vaccinations and history of refusing a doctor-recommended vaccine for their child(ren). RESULTS: About 47% of parents agreed that parents should have the right to refuse mandatory school vaccinations for their child(ren). Participants who reported their political affiliation as Republican (OR = 2.45, 95% CI: 1.28-4.66) or Independent (OR = 3.31, 95% CI: 1.70-6.44) were more likely to agree that parents should have the right to refuse school-mandated vaccinations than parents who reported their political affiliation as Democrat. Approximately 39% of parents reported ever refusing a vaccine for their child(ren). Participants who were female (OR = 3.90, 95% CI: 1.04-14.58) and believed that parents should have the right to refuse mandatory school vaccinations (OR = 3.27, 95% CI: 1.90-5.62) were more likely to report ever refusing a vaccine for their child(ren). CONCLUSION: The study findings provide information to better understand factors related to vaccination refusal among parents in Appalachia Ohio that can be used to design interventions to improve vaccination uptake.

RESUMO

BACKGROUND: Transition from pediatric to adult health care is a vulnerable period for adolescents and young adults. Challenges include paucity of validated measures to assess patients' transition readiness. We evaluated the Transition Readiness Assessment Questionnaire (TRAQ) in adolescents and young adults with rheumatic, gastrointestinal, and endocrine disorders. We examined whether baseline TRAQ scores and other demographic variables predicted transition to adult care over a three year follow up period. METHODS: In this descriptive study at a single institution, eighty-nine adolescents at a single pediatric academic medical center completed demographic and medical history surveys and the TRAQ and were followed over 3 years by telephone interview to determine whether they had transitioned to adult subspecialty care. Transition was defined as attending at least one adult subspecialty appointment. Multivariable logistic regression and Cox proportional hazards regression models were used to determine whether TRAQ scores predicted time to transition. RESULTS: Of the participants, 56% had rheumatic, 21% endocrine, and 23% gastrointestinal conditions. The TRAQ self-management domain score was not significantly associated with age, gender, socioeconomic status, or specialty. The TRAQ self-advocacy score increased with age. Baseline TRAQ scores did not predict transition or time to transition over three years. CONCLUSION: In this cohort of adolescents and young adults who were 16 to 23 years of age at enrollment, 48% transitioned to adult care over three years of follow up. Nearly half reported not discussing transition with provider or seeing provider independently for part of visit. Older age but not other demographic variables nor baseline TRAQ score predicted transition or time to transition to an adult subspecialty provider; however, a there was a trend towards shorter time to transition with the highest quartile TRAQ scores.

RESUMO

BACKGROUND: The Glasgow Coma Scale (GCS) is currently the most widely used scoring system for comatose patients. A decade ago, the Full Outline of Unresponsiveness (FOUR) score was devised to better capture four functional aspects of consciousness (eye, motor responses, brainstem reflexes, and respiration). This study aimed to validate the Chinese version of the FOUR score in patients with different levels of consciousness. METHODS: The study had two phases: (1) translation of the FOUR score, and (2) assessment of its reliability and validity. The Chinese version of the FOUR score was developed according to a standardized protocol. One hundred-twenty consecutive patients with acute brain damage, admitted to Nanfang Hospital (Southern Medical University, Guangdong, China) from November 2014 to February 2015, were enrolled. The inter-rater agreement for the FOUR score and GCS was evaluated using intraclass correlation coefficient (ICC). Receiver operating characteristic (ROC) curves were established to determine the scales' abilities to predict outcome. RESULTS: The rater agreement was excellent both for FOUR (ICC = 0.970; p < 0.001) and GCS (ICC = 0.958; p < 0.001). The FOUR score yielded an excellent test-retest reliability (ICC = 0.930; p < 0.001). Spearman's correlation coefficients between GCS and the FOUR score were high: r = 0.932, first rating; r = 0.887, second rating (all p < 0.001). Areas under the curve (AUC) for mortality were 0.834 (95 % CI, 0.740-0.928) and 0.815 (95 % CI, 0.723-0.908) for the FOUR score and GCS, respectively. CONCLUSIONS: The Chinese version of the FOUR score is a reliable scale for evaluating the level of consciousness in patients with acute brain injury.

RESUMO

OBJECTIVE: To study the associations of pedestrian injuries with age, income and educational level in Shanghai and to analyze the relative disease burden. METHODS: Information on pedestrian-related cases and deaths were collected from 494 hospitals and mortality registry systems from 1992 to 2010, and a multistage cluster sampling survey conducted in 2006. Logistic regression model was used in the analyses. RESULTS: The age group of 5-9 had the highest mortality and morbidity among children. Mortality increased obviously among those aged 60 or above. Individuals with an educational level under the primary school and with the lower family average income were more likely to suffer pedestrian-related injuries. Multivariate Logistic analysis demonstrated that lower income and lower educational level increased the risk of pedestrian injuries with the odds ratio of 1.40 (95% CI: 1.15-1.71) and 1.70 (95% CI: 1.20-2-40), respectively. About 13.54% of the share of GDP for the healthcare, social security and welfare industries in Shanghai was occupied by the burden of pedestrian-related injuries in 2006. CONCLUSION: Pedestrian-related injury has inverse association with victims' income and educational level. Children of 5-9 years old and adults over 60 with lower educational level and lower monthly income are the target persons to be intervened.

RESUMO

OBJECTIVES: In neonatal intensive care unit infants referred for home-tube feeding methods, we evaluated the effect of an innovative diagnostic and management approach on feeding outcomes at discharge and 1 year, by comparing data from historical controls; we hypothesized that clinical and aerodigestive motility characteristics at evaluation were predictive of feeding outcomes at discharge; we assessed the economic impact of feeding outcomes. PATIENTS AND METHODS: Patients (N = 100) who were referred for development of long-term feeding management strategy at 46.4 ±â€Š13.1 weeks' postmenstrual age were compared with 50 historical controls that received routine care. The focused approach included swallow-integrated pharyngoesophageal manometry, individualized feeding strategy, and prospective follow-up. Feeding success was defined as ability to achieve oral feedings at discharge and 1 year. Motility characteristics were evaluated in relation to feeding success or failure at discharge. RESULTS: Higher feeding success was achieved in the innovative feeding program (vs historical controls) at discharge (51% vs 10%, P < 0.0001) and at 1 year (84.3% vs 42.9%, P < 0.0001), at a reduced economic burden (P < 0.05). Contributing factors to the innovative program's feeding success (vs feeding failure) were earlier evaluation and discharge (both P < 0.05), greater peristaltic reflex-frequency to provocation (P < 0.05), normal pharyngeal manometry (P < 0.05), oral feeding challenge success (P < 0.05), and suck-swallow-breath-esophageal swallow sequence (P < 0.05). Probability of feeding success demonstrated a prediction rate of 79.6%. CONCLUSIONS: Short-term and long-term feeding outcomes in complex neonates can be significantly improved with innovative feeding strategies at a reduced cost. Clinical and aerodigestive motility characteristics were predictive of outcomes.

RESUMO

This paper conducted research on biomechanical characteristics and biological activity of concavity-convex amniotic membrane (CCAM) and discussed its superiority as ocular surface repair material. Folding and compression with vacuum of fresh amniotic membrane were used to prepare CCAM. After cutting the striga of CCAM, sixteen CCAM tissue section were chosen at random to test their tensile strength using electronic universal testing machine. The bilayer amniotic membrane (BAM), the double-deck amniotic membrane (DAM) and the monolayer amniotic membrane (MAM) were as controls. The test parameters included yield strength, tensile strength, elongation at break, elastic modulus and so on. The cytokines of fresh amniotic membrane (FAM), MAM and CCAM were analyzed by radioimmunoassay method. The CCAM was obviously thicker than MAM and DAM. After 15 min in PBS, the CCAM tissue can recover the normal shape. The tensile strength and the elongation at break of CCAM were higher than those of the MAM and the DAM (P < 0.05). The elastic modulus of the CCAM was smaller than that of the MAM and the DAM (P < 0.05). The content of 10 cytokines [epidermal growth factor (EGF), fibroblast growth factor (FGF), b-fibroblast growth factor b-FGF, hepatocyte growth factor (HGF), transforming growth factor-beta (TGF-beta), insulin-like growth factor (IGF), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), nerve growth factor (NGF), brain-derived nellrotrophic factor (BDNF), ciliary neurotrophic factor (CNTF)] of CCAM decreased significantly compared with the FAM and increased significantly compared with MAM and DAM in 6 cytokines (EGF, FGF, HGF, TGF-betap, PDGF, NGF; P < 0.05). The CCAM composites is thinner and has higher cytokine content than MAM, and better biomechanical properties than the MAM and the DAM, showing the superiority as ocular surface repair material.

RESUMO

The ketocarotenoid astaxanthin can be found in the microalgae Haematococcus pluvialis, Chlorella zofingiensis, and Chlorococcum sp., and the red yeast Phaffia rhodozyma. The microalga H. pluvialis has the highest capacity to accumulate astaxanthin up to 4-5% of cell dry weight. Astaxanthin has been attributed with extraordinary potential for protecting the organism against a wide range of diseases, and has considerable potential and promising applications in human health. Numerous studies have shown that astaxanthin has potential health-promoting effects in the prevention and treatment of various diseases, such as cancers, chronic inflammatory diseases, metabolic syndrome, diabetes, diabetic nephropathy, cardiovascular diseases, gastrointestinal diseases, liver diseases, neurodegenerative diseases, eye diseases, skin diseases, exercise-induced fatigue, male infertility, and HgCl2-induced acute renal failure. In this article, the currently available scientific literature regarding the most significant activities of astaxanthin is reviewed.

RESUMO

The effect of temperature, pH, the rate and time of oxidation, the concentration of ferrous ion in the starting suspensions as well as the amount of oxidant acting on the process of Fe(3)O(4) synthesis by Fe(OH)(2) suspensions are investigated. After 2h reaction at 90 degrees C under the oxidation of 10 g/L NH(4)NO(3), solution containing 0.25-0.35 mol/L iron(II) ion initially would yield the greatest amount of Fe(3)O(4), up to 95% Fe(3)O(4) could be formed. pH of the solution should be controlled between 9.0 and 11.0. X-ray diffraction (XRD) analysis shows that the product has spinel structure, which indicated that the product is Fe(3)O(4). Transmission electron microscopy (TEM) images show that the crystal size of ferrite is around 0.2 microm. The equilibrium composition of the synthesis reaction of Fe(3)O(4) is optimized by the minimization of the free energy of thermodynamics. It was found that the optimal condition for the synthesis of Fe(3)O(4) obtained through experiment is correspondent with that obtained through computer calculation. In the Fe(3)O(4) formation area given by Kiyama [M. Kiyama, Conditions for the formation of Fe(3)O(4) by the air oxidation of Fe(OH)(2) suspensions, Bull. Chem. Soc. Jpn. 47 (7) (1974) 1646-1650], the content of the product formed is not the same everywhere. The main factor that influences the content of the product is the amount of oxidant.
