The authors examined children's access to books in 153 four-year-olds from low-income, U.S. ethnic-minority families. Mothers reported on the number of books available to their children and the variety of books their children had, such as concept books about letters, numbers, and shapes and narrative books about cultural beliefs and relationships. Mothers also reported on the frequency of mother"child book-sharing interactions. The authors coded characteristics of book-sharing interactions from videos of mother"child sharing of a wordless book. Most children had a variety of concept books but few narrative books. Children who were later born and who had English-speaking (vs. Spanish-speaking) parents had a greater variety of narrative books than did their counterparts, and children living with their father and mother had a greater variety of narrative and concept books than those who did not reside with their father. The variety of narrative books predicted children's narrative contributions during book sharing through the mediator of mothers" questions about the story. In contrast, the variety of concept books predicted children's referential contributions (e.g., "That's a tree") through the mediator of mothers" referential questions (e.g., "What's that?"). Household composition, home language use, and the content of books shape the early literacy experiences of children from low-income, ethnic-minority families.

BACKGROUND:Low-income Hispanic women are at-risk of poor prenatal diet quality. Correlates associated with prenatal diet quality in this group of women are understudied. OBJECTIVE:The objective of this study was to examine the associations between financial, cultural, psychosocial, and lifestyle correlates and prenatal diet quality in low-income Hispanic women. DESIGN/METHODS:This cross-sectional analysis used data from pregnant women enrolled in the Starting Early Trial, a randomized-controlled trial of a primary-care based child obesity prevention program beginning in pregnancy. The trial enrolled women from clinics affiliated with a large urban medical center in New York City from 2012 to 2014. Financial, cultural, psychosocial, and lifestyle variables were collected using a comprehensive baseline questionnaire. Usual dietary intakes over the past year were assessed using the Block Food Frequency Questionnaire 2005 bilingual version. PARTICIPANTS/METHODS:The study enrolled low-income Hispanic women between 28 and 32 gestational weeks (N=519). MAIN OUTCOME MEASURES/METHODS:Prenatal diet quality was measured by the Healthy Eating Index 2015. STATISTICAL ANALYSES PERFORMED/METHODS:Unadjusted and adjusted multivariable linear regression analyses were performed to determine independent associations between financial, cultural, psychosocial, and lifestyle correlates and Healthy Eating Index 2015 total score. RESULTS:Overall prenatal diet quality was poor (mean Healthy Eating Index 2015 total score=69.0±9.4). Most women did not meet the maximum score for total vegetables (65.3%), whole grains (97.1%), dairy (74.8%), fatty acids (84.4%), refined grains (79.8%), sodium (97.5%), saturated fats (92.9%), and added sugars (66.5%). Women who reported screen time ≤2 hours/day, physical activity before and/or during pregnancy, and being born outside the United States had higher mean Healthy Eating Index 2015 total score than women with screen time >2 hours/day, no physical activity, and those born in the United States. CONCLUSIONS:Prenatal diet quality of low-income pregnant Hispanic women was suboptimal. This cross-sectional study revealed associations between cultural and lifestyle factors and prenatal diet quality in low-income Hispanic women. Longitudinal studies are needed to determine long-term influences and specific behaviors to target for effective intervention studies.

Background and Aims: Contemplating the use of N-acetylcysteine as a neuroprotectant, with dextran as an antithrombotic for patients with NIHSS less than or equal to 5, we quantified treatment-relevant clinical characteristics of a sample of this patient population at a single stroke center over one year.
Method(s): Patients with NIHSSResult(s): One-hundred twenty-eight of 310 (41%) patients with ischemic stroke had NIHSSConclusion(s): Minor stroke symptoms may not be captured by the current NIHSS. This population rarely had renal or hepatic failure, making them good candidates for combination N-acetylcysteine and dextran

BACKGROUND:Process evaluation is increasingly recognized as an important component of effective implementation research and yet, there has been surprisingly little work to understand what constitutes best practice. Researchers use different methodologies describing causal pathways and understanding barriers and facilitators to implementation of interventions in diverse contexts and settings. We report on challenges and lessons learned from undertaking process evaluation of seven hypertension intervention trials funded through the Global Alliance of Chronic Diseases (GACD). METHODS:Preliminary data collected from the GACD hypertension teams in 2015 were used to inform a template for data collection. Case study themes included: (1) description of the intervention, (2) objectives of the process evaluation, (3) methods including theoretical basis, (4) main findings of the study and the process evaluation, (5) implications for the project, policy and research practice and (6) lessons for future process evaluations. The information was summarized and reported descriptively and narratively and key lessons were identified. RESULTS:The case studies were from low- and middle-income countries and Indigenous communities in Canada. They were implementation research projects with intervention arm. Six theoretical approaches were used but most comprised of mixed-methods approaches. Each of the process evaluations generated findings on whether interventions were implemented with fidelity, the extent of capacity building, contextual factors and the extent to which relationships between researchers and community impacted on intervention implementation. The most important learning was that although process evaluation is time consuming, it enhances understanding of factors affecting implementation of complex interventions. The research highlighted the need to initiate process evaluations early on in the project, to help guide design of the intervention; and the importance of effective communication between researchers responsible for trial implementation, process evaluation and outcome evaluation. CONCLUSION/CONCLUSIONS:This research demonstrates the important role of process evaluation in understanding implementation process of complex interventions. This can help to highlight a broad range of system requirements such as new policies and capacity building to support implementation. Process evaluation is crucial in understanding contextual factors that may impact intervention implementation which is important in considering whether or not the intervention can be translated to other contexts.

Rates of physical inactivity continue to rise in the United States. With this work, we tested the efficacy of a strategy affecting the scope of visual attention designed to promote walking as a form of exercise. Specifically, we examined the influence of narrowed attention on the frequency (Studies 1a, 1b, and 3) and efficiency (Studies 2 and 4) of physical activity in general (Studies 1 and 2) and within exercise bouts measured across multiple days (Studies 3 and 4). We provide convergent evidence by investigating both individual differences in (Studies 1 and 2) and experimentally manipulated patterns of visual attention orienting (Studies 3 and 4). We discuss implications of attentional strategies for self-regulation and fitness.

Opsoclonus consists of bursts of involuntary, multidirectional, back-to-back saccades without an intersaccadic interval. We report a 60-year-old man with post-concussive headaches and disequilibrium who had small amplitude opsoclonus in left gaze, along with larger amplitude flutter during convergence. Examination was otherwise normal and brain MRI was unremarkable. Video-oculography demonstrated opsoclonus predominantly in left gaze and during pursuit in the left hemifield, which improved as post-concussive symptoms improved. Existing theories of opsoclonus mechanisms do not account for this eye position-dependence. We discuss theoretical mechanisms of this behavior, including possible dysfunction of frontal eye field and/or cerebellar vermis neurons; review ocular oscillations in traumatic brain injury; and consider the potential relationship between the larger amplitude flutter upon convergence and post-traumatic ocular oscillations.

INTRODUCTION/BACKGROUND:Young patients with breast cancer may face impaired fertility due to cancer treatments, which often leads to complex fertility decisions. To aid fertility decision-making, it is crucial that women have access to high-quality information; however, their fertility information needs are often unmet. Decision aids (DAs) are educational materials to assist with decision-making, by addressing individual values and preferences. In oncofertility, DAs may constitute a valuable resource to help patients obtain information and make better informed decisions. This paper reports on the protocol of the development and transcreation of a fertility-related DA booklet to support young Portuguese patients with breast cancer, originally developed and validated for an Australian audience. METHODS AND ANALYSIS/UNASSIGNED:Recent literature on clinical guidelines will be reviewed. A summary of these guidelines will be created and will inform the first round of DAs revisions. A forward translation process will translate the DA from Australian English to Portuguese. A multidisciplinary Portuguese experts panel will revise and give feedback on the scientific and cultural aspects of the DA content for Portuguese audience. Next, a backward translation process will assess content equivalence between the original and the final adapted version. Finally, Learner Verification (LV) will be used in a qualitative study of young patients with breast cancer and their partners. Two focus groups with 6-10 participants each will be conducted with: (1) recently diagnosed young patients with breast cancer; (2) breast cancer survivors and (3) their partners. Results from the DA acceptability assessment will inform its final version. Data will be analysed using content analysis and constant comparison method to identify key themes/textual units related to LV. ETHICS AND DISSEMINATION/UNASSIGNED:Ethical approval was granted by the Portuguese Institute of Oncology Porto. Results will be disseminated through peer-reviewed journals and presented at scientific meetings for academic and health professionals audiences.

BACKGROUND:Drug use is prevalent among electronic dance music (EDM) party attendees, but research is needed to determine the extent of adverse drug-related outcomes in this population in order to better inform prevention and harm reduction efforts. METHOD/METHODS:1029 adults were surveyed entering EDM parties in New York City in 2018. Those reporting past-year use of a drug were asked if they experienced a harmful or very unpleasant effect after use in which they were concerned about their immediate safety. They were also asked about co-use of other drugs and whether they sought help. RESULTS:We estimate that a third (33.5%) of EDM party attendees have experienced a drug-related adverse effect in the past year. Two-thirds (67.8%) of adverse effects involved use of alcohol. Relative to use, adverse effects most commonly resulted from use of opioids (e.g., prescription opioid misuse, 41.2%) or alcohol (33.9%). Among those reporting an adverse effect, concomitant use of other drugs was common, particularly among users of LSD (56.5%), ketamine (56.3%), cocaine (55.7%), and ecstasy/MDMA/Molly (47.7%). Adverse effects resulting from synthetic cathinone ("bath salt") use were most likely to result in a hospital visit (57.1%). CONCLUSION/CONCLUSIONS:Adverse effects from drug use are common among those in the EDM party scene and polydrug use appears to be a common risk factor. More research is needed, however, to determine the extent of event-specific adverse outcomes. Results can inform prevention and harm reduction efforts in this population.
