RESUMO

OBJECTIVE: This study aimed to examine the association between transportation assistance and study visits, and explore differences by transportation modality. STUDY DESIGN: This was a secondary analysis of prospective cohort study. We identified patients requesting transportation support for research ultrasound visits and identified controls (1:2 ratio) who did not request support matched for age, race, and insurance type. Conditional logistic regression examined the association between transportation support and mode of transportation with study visit attendance. RESULTS: Transportation support was requested by 57/1,184 (4.8%) participants. Participants that requested transportation support were three times more likely to attend visits than their matched controls (adjusted odds ratio [aOR] = 3.16, 95% confidence interval [CI]: 1.76-5.68). Among visits with transportation support, those supported by a ridesharing service had five-fold higher odds of attendance than visits supported with taxi service (aOR = 5.06, 95% CI: 1.50-16.98). CONCLUSION: Transportation support, especially a ridesharing service, is associated with improved attendance at research study visits in a sample of predominantly low-income, Black, pregnant participants. Implementing transportation support may be a promising strategy to improve engagement in research studies. KEY POINTS: · Participants utilizing transportation assistance were more likely to attend study appointments.. · Participants using ridesharing had higher likelihood of attendance than those using taxi service.. · Transportation assistance may improve research engagement for historically marginalized people..

RESUMO

Hox genes encode Homeodomain-containing transcription factors, which specify segmental identities along the anterior-posterior axis. Functional changes in Hox genes have been directly implicated in the evolution of body plans across the metazoan lineage. The Hox protein Ultrabithorax (Ubx) is expressed and required in developing third thoracic (T3) segments in holometabolous insects studied so far, particularly, of the order Coleoptera, Lepidoptera and Diptera. Ubx function is key to specify differential development of the second (T2) and T3 thoracic segments in these insects. While Ubx is expressed in the third thoracic segment in developing larvae of Hymenopteran Apis mellifera, the morphological differences between T2 and T3 are subtle. To identify evolutionary changes that are behind the differential function of Ubx in Drosophila and Apis, which are diverged for more than 350 million years, we performed comparative analyses of genome wide Ubx-binding sites between these two insects. Our studies reveal that a motif with a TAAAT core is a preferred binding site for Ubx in Drosophila, but not in Apis. Biochemical and transgenic assays suggest that in Drosophila, the TAAAT core sequence in the Ubx binding sites is required for Ubx-mediated regulation of two of its target genes studied here; CG13222, a gene that is normally upregulated by Ubx and vestigial (vg), whose expression is repressed by Ubx in T3. Interestingly, changing the TAAT site to a TAAAT site was sufficient to bring an otherwise unresponsive enhancer of the vg gene from Apis under the control of Ubx in a Drosophila transgenic assay. Taken together, our results suggest an evolutionary mechanism by which critical wing patterning genes might have come under the regulation of Ubx in the Dipteran lineage.

RESUMO

OBJECTIVE: A quality improvement initiative (QII) was conducted with five community-based health systems' oncology care centers (sites A-E). The QII aimed to increase referrals, genetic counseling (GC), and germline genetic testing (GT) for patients with ovarian cancer (OC) and triple-negative breast cancer (TNBC). METHODS: QII activities occurred at sites over several years, all concluding by December 2020. Medical records of patients with OC and TNBC were reviewed, and rates of referral, GC, and GT of patients diagnosed during the 2 years before the QII were compared to those diagnosed during the QII. Outcomes were analyzed using descriptive statistics, two-sample t-test, chi-squared/Fisher's exact test, and logistic regression. RESULTS: For patients with OC, improvement was observed in the rate of referral (from 70% to 79%), GC (from 44% to 61%), GT (from 54% to 62%) and decreased time from diagnosis to GC and GT. For patients with TNBC, increased rates of referral (from 90% to 92%), GC (from 68% to 72%) and GT (81% to 86%) were observed. Effective interventions streamlined GC scheduling and standardized referral processes. CONCLUSION: A multi-year QII increased patient referral and uptake of recommended genetics services across five unique community-based oncology care settings.

RESUMO

OBJECTIVE: To evaluate whether participation in CenteringPregnancy group prenatal care is associated with decreased risk of an interpregnancy interval (IPI) ≤6 months. STUDY DESIGN: We conducted a retrospective cohort study of women enrolled in Missouri Medicaid from 2007 to 2014 using maternal Medicaid data linked to infant birth certificate records. Inclusion criteria were women ≥11 years old, ≥1 viable singleton delivery during the study period, residency in St. Louis city or county, and ≥2 prenatal visits. The primary outcome was an IPI ≤6 months. Secondary outcomes included IPI ≤12 months, IPI ≤18 months, postpartum long-acting reversible contraception (LARC) uptake, and postpartum LARC or depot medroxyprogesterone acetate (DMPA) uptake. Data were analyzed using descriptive statistics and logistic regression. Backward stepwise logistic regression was used to adjust for potential confounders including maternal age, race, obesity, nulliparity, marital status, diabetes, hypertension, prior preterm birth, and maternal education. RESULTS: Of the 54,968 pregnancies meeting inclusion criteria, 1,550 (3%) participated in CenteringPregnancy. CenteringPregnancy participants were less likely to have an IPI ≤6 months (adjusted odds ratio [aOR]: 0.61; 95% confidence interval [CI]: 0.47-0.79) and an IPI ≤12 months (aOR: 0.74; 95% CI: 0.62-0.87). However, there was no difference for an IPI ≤18 months (aOR: 0.89; 95% CI: 0.77-1.13). Women in CenteringPregnancy were more likely to use LARC for postpartum contraception (aOR: 1.37; 95% CI: 1.20-1.57). CONCLUSION: Participation in CenteringPregnancy is associated with a significant decrease in an IPI ≤6 and ≤12 months and a significant increase in postpartum LARC uptake among women enrolled in Missouri Medicaid compared with women in traditional prenatal care. KEY POINTS: · CenteringPregnancy is associated with a significant decrease in interpregnancy intervals ≤6 and ≤12 months.. · LARC uptake is significantly higher among patients participating in CenteringPregnancy.. · CenteringPregnancy participation enhances self-efficacy in making contraception decisions and promotes healthy pregnancy spacing..

RESUMO

Hox proteins are major regulators of embryonic development, acting in the nucleus to regulate the expression of their numerous downstream target genes. By analyzing deletion forms of the Drosophila Hox protein Ultrabithorax (Ubx), we identified the presence of an unconventional nuclear export signal (NES) that overlaps with a highly conserved motif originally described as mediating the interaction with the PBC proteins, a generic and crucial class of Hox transcriptional cofactors that act in development and cancer. We show that this unconventional NES is involved in the interaction with the major exportin protein CRM1 (also known as Embargoed in flies) in vivo and in vitro We find that this interaction is tightly regulated in the Drosophila fat body to control the autophagy-repressive activity of Ubx during larval development. The role of the PBC interaction motif as part of an unconventional NES was also uncovered in other Drosophila and human Hox proteins, highlighting the evolutionary conservation of this novel function. Together, our results reveal the extreme molecular versatility of a unique short peptide motif for controlling the context-dependent activity of Hox proteins both at transcriptional and non-transcriptional levels.

RESUMO

OBJECTIVES: There is limited guidance on how to effectively educate cancer survivors to adopt and maintain specific diet and physical activity recommendations, especially among underserved and under-resourced populations. Here, the objective is to present the development of a behavioral and theoretically-based multi-modal diet and physical activity intervention program for Hispanic/Latina breast cancer survivors, Mi Vida Saludable (My Healthy Life). METHODS: The development process was based on the 6 steps of the Nutrition Education DESIGN Procedure: (1). Decide behaviors; (2). Explore determinants; (3). Select theory-based model; (4). Indicate objectives; (5). Generate plans; and (6). Nail down evaluation. The theoretical framework for the intervention is Social Cognitive Theory. RESULTS: The resulting behavioral intervention consists of 2 components. The first component is in-person group education consisting of 4 lessons over 1 month. Each 4-hour group lesson includes a hands-on cooking component, a physical activity component, and facilitator-led nutrition education and discussion, with 2 field trips to a local grocery store and farmers' market. The second component is an e-Health program that includes weekly text messages, biweekly emailed newsletters, and ongoing website access. CONCLUSION: The systematic DESIGN Procedure provided practical guidance for developing a behaviorally-focused, theory-based, and culturally sensitive program that addresses both dietary and physical activity behaviors for delivery both in-person education and through eHealth. The Procedure may be useful for developing other behaviorally focused and theory-based interventions.

RESUMO

Mechanistic modeling indicates that stomatal conductance could be reduced to improve water use efficiency (WUE) in C4 crops. Genetic variation in stomatal density and canopy temperature was evaluated in the model C4 genus, Setaria. Recombinant inbred lines (RILs) derived from a Setaria italica×Setaria viridis cross were grown with ample or limiting water supply under field conditions in Illinois. An optical profilometer was used to rapidly assess stomatal patterning, and canopy temperature was measured using infrared imaging. Stomatal density and canopy temperature were positively correlated but both were negatively correlated with total above-ground biomass. These trait relationships suggest a likely interaction between stomatal density and the other drivers of water use such as stomatal size and aperture. Multiple quantitative trait loci (QTL) were identified for stomatal density and canopy temperature, including co-located QTL on chromosomes 5 and 9. The direction of the additive effect of these QTL on chromosome 5 and 9 was in accordance with the positive phenotypic relationship between these two traits. This, along with prior experiments, suggests a common genetic architecture between stomatal patterning and WUE in controlled environments with canopy transpiration and productivity in the field, while highlighting the potential of Setaria as a model to understand the physiology and genetics of WUE in C4 species.

RESUMO

BACKGROUND: The aim of the study was to describe and contrast the brain development and outcome among very preterm infants that were and were not exposed to surgery requiring general anesthesia prior to term equivalent age (TEA). METHODS: Preterm infants born ≤30 weeks' gestation who did (n = 25) and did not (n = 59) have surgery requiring general anesthesia during the preterm period were studied. At TEA, infants had MRI scans performed with measures of brain tissue volumes, cortical surface area, Gyrification Index, and white matter microstructure. Neurodevelopmental follow-up with the Bayley Scales of Infant and Toddler Development, Third Edition was undertaken at 2 years of corrected age. Multivariate models, adjusted for clinical and social risk factors, were used to compare the groups. RESULTS: After controlling for clinical and social variables, preterm infants exposed to surgical anesthesia demonstrated decreased relative white matter volumes at TEA and lower cognitive and motor composite scores at 2-year follow-up. Those with longer surgical exposure demonstrated the greatest decrease in white matter volumes and lower cognitive and motor outcomes at age 2 years. CONCLUSIONS: Very preterm infants who required surgery during the preterm period had lower white mater volumes at TEA and worse neurodevelopmental outcome at age 2 years. IMPACT: In very preterm infants, there is an association between surgery requiring general anesthesia during the preterm period and reduced white mater volume on MRI at TEA and lower cognitive and motor composite scores at age 2 years. It is known that the very preterm infant's brain undergoes rapid growth during the period corresponding to the third trimester. The current study suggests an association between surgery requiring general anesthesia during this period and worse outcomes.

RESUMO

PURPOSE OF REVIEW: In this manuscript, we present recent findings concerning concordance and discrepancy between biological measures and self-reports of these three outcomes of HIV programs: HIV status, adherence to antiretroviral medications (ARVs) and use of and adherence to pre-exposure prophylaxis medication (PrEP), and condom use/unprotected sex. RECENT FINDINGS: Recent studies suggest that three successive rapid HIV tests (for those whose first test in positive) might be reasonably inexpensive and valid biological data to collect to combine with self-reports of HIV status, dried blood spots sufficiently affordable to combine with self-reports of adherence to ARVs and use of or adherence to PrEP, and that the discrepancy between self-reports of condom use and biomarkers of unprotected sex may be relatively small in high-income countries. Additional work on assessment of incorrect condom usage and breakage, standardized self-report measures of condom use, and more private data collection methodologies in low-income settings might reduce the recent observed discrepancies even further. Concordance between self-reports of HIV and biomarkers indicating HIV positive status has varied considerably, with much lower rates in low-income countries, where the stigma of HIV is still very high. Recommendation is for combining self-report data with the results of three successive rapid tests for those testing positive. For adherence, again agreement between self-reports and a variety of more objective and/or biological measures is only moderate. Dried blood spots (DBS) may be sufficiently inexpensive in low-resource settings that this may be the best biological method to combine with self-reports. In publications over the last 8 years, the discrepancy between self-reports of condom use and biomarkers for unprotected sex may be even lower than 20% after controlling for other features of the study, particularly in high-income countries. Our results suggest that more careful assessment of incorrect condom use and breakage as reasons other than intentional misreporting should be investigated more carefully and that more private data collection methods such as audio, computer-assisted self-interviewing (ACASI) might be employed more often in low-resource settings to reduce this discrepancy in those settings further. In addition, further analysis of the discrepancy between self-reports of condom use and biomarkers should be conducted of published studies using the correct calculation methods to be more certain of these findings.

RESUMO

The COVID-19 pandemic rapidly changed genetic counseling services across the United States. At the University of Pennsylvania (UPenn), a large academic hospital in an urban setting, nearly all genetic counseling (GC) visits for adult-onset disorders within the Department of Neurology were conducted via secure videoconferencing (telegenetics) or telephone between March and December 2020. Although telemedicine services have been steadily emerging, many clinical programs, including the neurogenetics program at UPenn, had not built infrastructure or widely utilized these services prior to the pandemic. Thus, little is known about patient attitudes toward receiving clinical GC services remotely. From May 18 to October 18, 2020, all individuals seen remotely for GC in adult neurology via telephone or telegenetics were surveyed about their satisfaction with telehealth GC (N = 142), with a response rate of 42% (N = 60/142). Telephone and telegenetics services were referred to as 'telehealth' in the surveys to capture patient perspectives on all remote GC services, though the majority (N = 49/60) of these visits were completed via telegenetics. Surveys included the modified telehealth usability questionnaire (MTUQ), genetic counseling satisfaction scale (GCSS), and novel questions about future telehealth use. Preliminary results suggest that patients were satisfied with receiving remote GC services in adult neurology, with most participants strongly agreeing to all items about satisfaction with telehealth. Just 2% of participants preferred only in-person visits in the future, but every participant was willing to consider using telehealth for future visits if their genetic counselor felt it was appropriate. Most participants preferred a hybrid model (73%), and some (25%) preferred only telehealth for future visits. Additionally, we found no differences in satisfaction with remote services based on visit type (initial vs. results disclosure) nor age. We conclude that remote GC is an acceptable method for the provision of services in adult neurology that is well-received by patients.

RESUMO

BACKGROUND: Contraceptive choice is a preference-sensitive decision that is affected by contraceptive attributes, patient experience, and reproductive history. Familiarity with and acceptability of specific contraceptive methods may influence patient decisions. OBJECTIVE: The purpose of this study was to describe the acceptability of and previsit familiarity with long-acting reversible contraception (intrauterine devices and contraceptive implants) compared with depo-medroxyprogesterone acetate and oral contraceptive pills in women seeking contraceptive care and to investigate the relationship between acceptability and contraceptive choice. STUDY DESIGN: This was a secondary analysis of a study that was designed to compare 2 contraceptive care programs conducted at 3 Midwest federally qualified health centers. After contraceptive counseling, participants completed a baseline interviewer-administered survey before the healthcare provider visit. We asked participants questions about previsit familiarity with and acceptability of the intrauterine device, implant, depo-medroxyprogesterone acetate, and oral contraceptive pills. We assessed familiarity using 2 questions: (1) Before today have you ever heard of the [method]? (2) Do you know any woman who has/has used the [method]? Acceptability was assessed for each method on a 0-10 scale, with 0 being "strongly dislike" and 10 being "strongly like." We dichotomized the scores into high acceptability (7-10) and low/moderate acceptability (0-6) for analysis. We examined differences in demographic and reproductive characteristics between women with high and low long-acting reversible contraception acceptability using the chi-square test. We used univariate and multivariable Poisson regressions to examine the relationship among participants' characteristics, method acceptability, and method choice. We adjusted for any covariate that changed the effect size of acceptability by >10%. RESULTS: There were 1007 women included in the analysis: 900 women (89%) reported that they had heard of the intrauterine device, and 592 women (59%) knew someone who had used the intrauterine device. Eight hundred sixty-five (86%) women had heard of the implant, and 636 women (63%) knew someone who had used it. Knowledge of depo-medroxyprogesterone acetate and oral contraceptive pills was high (>98% for both). Five hundred seventy-six women (57%) found 1 or both long-acting reversible contraception methods highly acceptable. Women with high long-acting reversible contraception acceptability were more likely to be adolescents or aged 30-45 years, white, Hispanic, married/cohabitating, and uninsured and were less likely to desire a child in the next 1-3 years. They were more likely to desire a hormonal intrauterine device (90.5% vs 9.5%), copper intrauterine device (81.1% vs 18.9%), or implant (89.8% vs 10.2%) compared with women with low acceptability (P<.001). In adjusted analyses, women with high acceptability of an intrauterine device were more likely to desire an intrauterine device (adjusted relative risk, 9.62; 95% confidence interval, 6.42-14.42). Women with high acceptability of an implant were also more likely to desire one (adjusted relative risk, 8.74; 95% confidence interval, 6.17-12.38). Women were more likely to desire an intrauterine device or an implant if they knew someone who used the method. Previous use of the method and demographic factors were not associated with method choice. CONCLUSION: Previsit familiarity with intrauterine devices and implants was high in our federally qualified health centers population, although not as high as depo-medroxyprogesterone acetate and oral contraceptive pills. In adjusted analyses, women who found an intrauterine device or implant highly acceptable and who knew someone who had used the method were more likely to choose those respective methods at the end of their visit.

RESUMO

BACKGROUND: Very preterm (VPT; <30 weeks gestation) children are a heterogeneous group, yet the co-occurrence of psychiatric and neurodevelopmental impairments remains unclear. Moreover, the clinical and socio-environmental factors that promote resilient developmental outcomes among VPT children are poorly understood. METHODS: One hundred and twenty five children (85 VPT and 40 full-term) underwent neurodevelopmental evaluation at age 5-years. Parents and teachers completed measures of internalizing, externalizing, attention-deficit/hyperactivity (ADHD), and autism symptoms. Psychiatric and neurodevelopmental measures were analyzed using Latent Profile Analysis. Multinomial regression examined the extent that infant, sociodemographic, and family factors, collected prospectively from birth to follow-up, independently differentiated resilient and impaired children. RESULTS: Four latent profiles were identified, including a Typically Developing Group which represented 27.1% of the VPT group and 65.0% of the full-term group, an At-Risk Group with mild psychiatric and neurodevelopmental problems (VPT 44.7%, full-term 22.5%), a Psychiatric Group with moderate-to-severe psychiatric ratings (VPT 12.9%, full-term 10.0%), and a school-based Inattentive/Hyperactive Group (VPT 15.3%, full-term 2.5%). Clinical diagnoses were highest among the Psychiatric Group (80%). Factors that differentiated resilient and impaired subgroups of VPT children included prolonged exposure to maternal psychosocial distress (p ≤ .04), current family dysfunction (p ≤ .05), and maternal ADHD symptoms (p ≤ .02), whereas social risk index scores differentiated resilient and impaired full-term children (p < .03). CONCLUSIONS: Lower levels of maternal distress, family dysfunction, and maternal ADHD symptoms were associated with resilience among VPT children. Maternal distress and family dysfunction are modifiable factors to be targeted as part of psychiatric interventions embedded in the long-term care of VPT children.

RESUMO

Vertical growth of plants is a dynamic process that is influenced by genetic and environmental factors and has a pronounced effect on overall plant architecture and biomass composition. We have performed six controlled growth trials of an interspecific Setaria italica x Setaria viridis recombinant inbred line population to assess how the genetic architecture of plant height is influenced by developmental queues, water availability and planting density. The non-destructive nature of plant height measurements has enabled us to monitor height throughout the plant life cycle in both field and controlled environments. We find that plant height is reduced under water limitation and high density planting and affected by growth environment (field vs. growth chamber). The results support a model where plant height is a heritable, polygenic trait and that the major genetic loci that influence plant height function independent of growth environment. The identity and contribution of loci that influence height changes dynamically throughout development and the reduction of growth observed in water limited environments is a consequence of delayed progression through the genetic program which establishes plant height in Setaria. In this population, alleles inherited from the weedy S. viridis parent act to increase plant height early, whereas a larger number of small effect alleles inherited from the domesticated S. italica parent collectively act to increase plant height later in development.

RESUMO

OBJECTIVE: To assess the extent to which social and family factors explain variability in cognitive, language, and motor development among very preterm (<30 weeks of gestation) children from 2 to 5 years of age. STUDY DESIGN: As part of a longitudinal study, very preterm children recruited as neonates were assessed at 2 (n = 87) and 5 (n = 83) years of age using standardized tests of cognitive, language, and motor ability alongside demographically matched full term (FT) children (n = 63). For very preterm children, developmental change scores were calculated for each domain to assess within-individual variability to 5 years of age. Multivariate regression and mixed-effect models examined social risk index, parenting stress, family functioning, and maternal intellectual ability as predictors of developmental variation among very preterm children. RESULTS: Very preterm children demonstrated poorer cognitive, language, and motor abilities than FT children at 2 (P ≤ .001) and 5 (P < .002) years of age. Social adversity was associated with cognitive (P < .001) and language (P < .001) outcomes at both ages, with parenting stress also related to cognitive outcomes (P = .03). Infant medical risk was associated with motor outcome at 5 years (P=.01). Very preterm children showed considerable within-individual variation between assessments. Among very preterm children, neonatal white matter abnormalities predicted worsening cognitive (P=.04) and motor development (P = .01). Social risk index predicted worsening language development (P = .04), but this association was subsequently explained by dysfunctional maternal affective involvement (P = .01) and lower maternal intellectual ability (P = .05). CONCLUSIONS: Both clinical and socioenvironmental factors are associated with cognitive, language, and motor developmental variation among very preterm children from infancy to early school age.

RESUMO

BACKGROUND: Sociodemographic factors are linked to cognitive outcomes in children born very preterm (VPT; ≤30 weeks gestation). The influence of maternal intellectual ability, a heritable trait, is unknown. Also undetermined is the extent to which associations between maternal and child intellectual ability vary according to parenting behaviors that target cognitive stimulation in the home. METHODS: At age 5 years, 84 VPT and 38 demographically matched full-term (FT) children underwent neurodevelopmental assessment. Children's intellectual ability was assessed using The Wechsler Preschool Primary Scale of Intelligence-III, and language was assessed with the Clinical Evaluation of Language Fundamentals Preschool-2. The Wechsler Test of Adult Reading estimated maternal intellectual ability. The StimQ-Preschool questionnaire provided a measure of cognitive stimulation in the home. Linear mixed-effects models examined independent effects and interactions between maternal intellectual ability and cognitive stimulation on children's outcomes. RESULTS: After covariate adjustment, maternal intellectual ability was associated with child intellectual (p < .001) and language (p = .002) abilities. Stronger associations were observed in FT mother-child dyads (B = .63, p = .04) than VPT dyads (B = .42, p = .01). Mothers of VPT children reported lower levels of Parental Involvement in Developmental Advance (p = .007) and Parental Verbal Responsiveness (p = .04). Group differences in Parental Involvement in Developmental Advance, but not Parental Verbal Responsivity, persisted after adjusting for social background (p = .03). There was no evidence of an interaction between maternal intellectual ability and Parental Involvement in Developmental Advance (p = .34). Instead, maternal intellectual ability (p < .001) and Parental Involvement in Developmental Advance (p = .05) independently predicted VPT children's outcomes. CONCLUSIONS: Maternal intellectual ability is an important trait linked to VPT and FT children's intellectual and language outcomes. Prematurity increases variation in the heritability of intellectual ability and shifts children from the expected range based on maternal ability. Parental involvement in activities that help children master new skills may promote cognitive development in VPT children born to mothers of lower intellectual ability.

RESUMO

OBJECTIVE: To examine psychosocial mediators of the effect of a culturally tailored dietary intervention on dietary change among Hispanic/Latina breast cancer survivors. METHODS: Hispanic/Latina breast cancer survivors (n = 70) were randomized to receive either a 12-week theory-based and culturally tailored dietary change program (intervention group, n = 34), or standard-of-care printed recommendations (control group, n = 36) (ClinicalTrials.gov NCT01414062). Fruit/vegetable intake (F/V), % calories from fat, and hypothesized psychosocial mediators were assessed at baseline, 6 and 12 months. Analysis of covariance assessed intervention effects on psychosocial mediators at 6 and 12 months. Mediation analysis using the bootstrap method evaluated the indirect intervention effects on dietary intake at 6 and 12 months through changes in psychosocial mediators at 6 and 12 months. RESULTS: Compared with controls, at 6 and 12 months, the intervention group reported greater improvements in stages of change (P < .001, P < .001, respectively), self-efficacy (P = .009, P = .002, respectively), snack preference for F/snack preference for F/V (P = .045, P = .002, respectively); at 12 months, the intervention group reported a decrease in chance-oriented external locus of control (P = .02). At 6 months, mediation analysis showed that the intervention effect was associated with an increase of 1.0 (95% CI, -0.1-2.4) serving/day of F/V, compared with the control group, although no indirect effect through the hypothesized psychosocial mediators was observed. At 12 months, the intervention was associated with an increase in 0.5 serving/day F/V through improved taste/snack preference for F/V at 6 and 12 months (95% CIs, 0.1-1.3, 0.0-1.4, respectively). CONCLUSIONS: Future programs can target improving taste/snack preference for F/V to promote dietary change in Hispanic/Latina breast cancer survivors.

RESUMO

Background Childhood obesity is a major public health concern and families play an important role. Improving strategies to reach parents and directing tailored nutrition education to them is needed. Purpose To investigate the challenges and facilitators to promoting a healthy environment at home and to identify communication preferences to inform intervention strategies for effectively reaching low-income urban minority families. Procedure Semi-structured focus group interviews were conducted with four groups involving 16 low-income urban parents (94% female; 88% Hispanic/Latino, 12% African American) of elementary school children. Interviews were transcribed and analyzed applying Social Cognitive Theory and using in-vivo coding. Main Findings The most common barriers to parents providing healthy foods to their children were accommodating child preferences and familial opposition. Parents showed intentionality to engage in healthy behaviors, and often shared procedural knowledge for reaching health goals. The analyses of desired communication channels yielded major preferences: tailored information, information provided through multiple mediums, appropriate duration/frequency of messages, and presented from a voice of authority. Conclusion and Implication While parents expressed desires to be healthy, the home food environment presented substantial challenges. Multi-media supports such as workshops, flyers, and text messaging may be useful to facilitate the sharing of information to minimize the tensions between intentionality and reaching desired goals to be healthy. Some parents thought that information received through text messaging could be easily shared and would act as a voice of authority to support child behavior change.

RESUMO

Under the Hospital-Acquired Condition Reduction Program (HACRP), introduced by the Affordable Care Act, the Centers for Medicare and Medicaid must reduce reimbursement by 1% for hospitals that rank among the lowest performing quartile in regard to hospital-acquired conditions (HACs). This study seeks to determine whether Accredited Cancer Program (ACP) hospitals (as defined by the American College of Surgeons) score differently on the HACRP metrics than nonaccredited cancer program hospitals. This study uses data from the 2014 American Hospital Association Annual Survey database, the 2014 Area Health Resource File, the 2014 Medicare Final Rule Standardizing File, and the FY2017 HACRP database (Medicare Hospital Compare Database). The association between ACPs, HACs, and market characteristics is assessed through multinomial logistic regression analysis. Odds ratios and 95% confidence intervals are reported. Accredited cancer hospitals have a greater risk of scoring in the Worse outcome category of HAC scores, vs Middle or Better outcomes, compared with nonaccredited cancer hospitals. Despite this, they do not have greater odds of incurring a payment reduction under the HACRP measurement system. While ACP hospitals can likely improve scores, questions concerning the consistency of the message between ACP hospital quality and HACRP quality need further evaluation to determine potential gaps or issues in the structure or measurement. ACP hospitals should seek to improve scores on domain 2 measures. Although ACP hospitals do likely see more complex patients, additional efforts to reduce surgical site infections and related HACs should be evaluated and incorporated into required quality improvement efforts. From a policy perspective, policy makers should carefully evaluate the measures utilized in the HACPR.

RESUMO

BACKGROUND: Childhood obesity prevention is a pressing issue. Understanding the relationships among eating and physical activity behaviors and potential psychosocial determinants of behavior will help us design more effective interventions. This study aimed to examine such relationships in a large sample of urban elementary school children. METHODS: Fifth grade students in 20 recruited New York City public schools completed a validated questionnaire on six "do more" (fruits and vegetables and physical activity) and "do less" (sweetened beverages, processed packaged snacks, fast food and sedentary behavior) energy balance related behaviors (EBRBs) and psychosocial determinants of behavior from social cognitive and self-determination theories. Correlations among behaviors and hierarchical linear model analyses of the relationship between psychosocial determinants and behaviors were conducted for those with complete data (n = 952). RESULTS: The "do more" and the "do less" behaviors were significantly correlated within categories (p < 0.01). "Do more" food-related behaviors were correlated with physical activity but so were sports drinks, while the "do less" food-related behaviors tended to be correlated to sedentary behavior (p < 0.01). "Do more" behaviors were associated with self-efficacy and habit strength, and "do less" behaviors with outcome expectations, self-efficacy, habit strength, and behavioral intention. CONCLUSIONS: Interventions can address the healthy and less healthy clusters of behaviors together, focusing on strategies to enhance their self-efficacy and habit strength for the "do more" behaviors and outcome expectations to motivate intention to choose fewer "do less" behaviors, along with enhancing self-efficacy and habit. Research can examine these determinants as potential mediators of change in intervention.

RESUMO

Introduction: Elevating Voices, Addressing Depression, Toxic Stress and Equity (EleVATE) is a group prenatal care (GC) model designed to improve pregnancy outcomes and promote health equity for Black birthing people. This article outlines the foundational community-engaged process to develop EleVATE GC and pilot study results. Methods: We used community-based participatory research principles and the Ferguson Commission Report to guide creation of EleVATE GC. The intervention, designed by and for Black birthing people, centers trauma-informed care, antiracism, and integrates behavioral health strategies into group prenatal care to address unmet mental health needs. Using a convenience sample of patients seeking care at one of three safety-net health care sites, we compared preterm birth, small for gestational age, depression scores, and other pregnancy outcomes between patients in individual care (IC), CenteringPregnancy™ (CP), and EleVATE GC. Results: Forty-eight patients enrolled in the study (n=11 IC; n=14 CP; n=23 EleVATE GC) and 86% self-identified as Black. Patients participating in group prenatal care (EleVATE GC or CP) were significantly less likely to experience a preterm birth <34 weeks. Rates of small for gestational age, preterm birth <37 weeks, depression scores, and other pregnancy outcomes were similar across groups. Participants in CP and EleVATE GC were more likely to attend their postpartum visit and breastfeed at hospital discharge than those in IC. Discussion: Our findings model a systematic approach to design a feasible, patient-centered, community-based, trauma-informed, antiracist intervention. Further study is needed to determine whether EleVATE GC improves perinatal outcomes and promotes health equity.
