Abstract
OBJECTIVE In 2020, Mexico implemented innovative front-of-package nutrition warning labels (FoPWLs) for packaged foods to increase the salience and understanding of nutrition information. This study evaluated Mexican Americans' self-reported exposure to Mexican FoPWLs and self-reported effects of FoPWLs on purchasing behavior. METHODS The 2021 International Food Policy Study surveyed online panels of adult Mexican Americans in the US (n = 3361) to self-report on buying food at Mexican-oriented stores, noticing Mexican FoPWLs, and being influenced by FoPWLs to purchase less of eight different unhealthy foods (each assessed separately). After recoding the frequency of buying foods in Mexican stores and noticing FoPWLs (i.e., "often" or "very often" vs. less often), logistic models regressed these outcomes on sociodemographics, adjusting for post-stratification weights. RESULTS Most participants (88.0%) purchased foods in Mexican stores. Of these, 64.1% reported noticing FoPWLs, among whom many reported that FoPWLs influenced them to buy fewer unhealthy foods (range = 32% [snacks like chips] - 44% [colas]). Participants were more likely to buy foods in Mexican stores and notice FoPWLs if they were younger, had ≥two children at home vs no children (AOR = 1.40, 95%CI = 1.15-1.71; AOR = 1.37, 95%CI = 1.03-1.80, respectively), and more frequently used Spanish (AOR = 1.91, 95%CI = 1.77-2.07; AOR = 1.87, 95%CI = 1.69-2.07). Also, high vs. low education (AOR = 1.51, 95%CI = 1.17-1.94) and higher income adequacy (AOR = 1.37, 95%CI = 1.25-1.51) were positively associated with noticing FoPWLs. Being female and more frequent Spanish use were consistently associated with reporting purchase of fewer unhealthy foods because of FoPWLs. CONCLUSIONS Many Mexican Americans report both exposure to Mexican FOPWLs and reducing purchases of unhealthy foods because of them.

Abstract
Background Gamification represents a promising approach for facilitating positive social interactions among groups of individuals and is increasingly being leveraged in physical activity (PA) interventions to promote enhanced intervention engagement and PA outcomes. Although African American (AA) adults experience disparities associated with health conditions that can be ameliorated with increased PA, little is known about how best to culturally target PA gamification strategies for this population. The purpose of this study was to gather perspectives from AA adults residing in the Southeast United States and subsequently identify themes to help inform the cultural adaptation of an existing electronic and mobile health (e/mHealth) gamification- and theory-based PA intervention for teams of insufficiently active AA adults. Methods An AA moderator facilitated six online focus groups among AA adults (n=42; 93% female; 45.09±9.77 years; 34.40±57.38 minutes/week of reported moderate-intensity equivalent PA), using a semi-structured focus group guide. Drawing from a content analysis approach, transcripts were coded and salient themes were identified. Results The focus groups revealed the following seven themes: (I) motivation (team-based gamification motivating); (II) accountability (team-based gamification promotes accountability); (III) competition (competitive elements attractive); (IV) weekly challenges (prefer to choose weekly PA challenges); (V) leaderboard feedback (preference for viewing steps and active minutes via a leaderboard); (VI) cultural relevancy (prefer elements reflective of their race and culture that promote team unity); (VII) teammate characteristics (mixed preferences regarding ideal sociodemographic characteristics and starting PA level of teammates). Conclusions Integrating team-based gamification in an e/mHealth-based PA intervention may be acceptable among AA adults. The identification of specific design preferences and perceptions of the value of the social environment points to the need to consider surface-level and deep structure cultural targeting when developing and further exploring best practices regarding gamified PA interventions for insufficiently active AAs.

Abstract
OBJECTIVE Front-of-package warning labels introduced in Mexico in 2020 included disclaimers that caution against allowing children to consume products with non-sugary sweeteners and caffeine. We examined the awareness and use of the disclaimers among Mexican adults and youth 1 month after the regulation was implemented. We also investigated their impact on the perceived healthfulness of industrialised beverages designed for children. DESIGN Data on the awareness and use of the disclaimers were analysed. Two between-subjects experiments examined the effect of a sweetener disclaimer (Experiment 1, youth and adults) or a caffeine disclaimer (Experiment 2, only adults) on the perceived healthfulness of industrialised beverages. Interactions between experimental conditions and demographic characteristics were tested. SETTING Online survey in 2020. PARTICIPANTS Mexican adults (≥18 years, n 2108) and youth (10-17 years, n 1790). RESULTS Most participants (>80 %) had seen the disclaimers at least rarely, and over 60 % used them sometimes or frequently. The sweetener disclaimer led to a lower perceived healthfulness of a fruit drink (adults: 2·74 ± 1·44; youth: 2·04 ± 0·96) compared with the no-disclaimer condition (adults: 3·17 ± 1·54; youth: 2·32 ± 0·96) (t's: >4·0, P values: <0·001). This effect was larger among older adults and male youth. The caffeine disclaimer did not affect adult's perceived healthfulness of a caffeinated drink (t = 0·861, P value = 0·3894). CONCLUSIONS There were high awareness and use of the sweeteners and caffeine disclaimers shortly after the warning labels were implemented. The sweetener disclaimer appears to be helping consumers modify their perceptions regarding industrialised beverages for children. Findings may help decision-makers improve the regulation and better target communication strategies.

Abstract
In this article, we examine progress and challenges in designing, implementing, and evaluating culturally sensitive behavioral interventions by tailoring health communication to groups or individuals. After defining common tailoring constructs (i.e., culture, race, and ethnicity), cultural sensitivity, and cultural tailoring, we examine when it is useful to culturally tailor and address cultural sensitivity in health communication by group tailoring or individual tailoring and when tailoring health communication may not be necessary or appropriate for achieving behavior change. After reviewing selected approaches to cultural tailoring, we critique the quality of research in this domain with a focus on the internal validity of empirical findings. Then we explore the ways in which cultural sensitivity, group targeting, and individual tailoring have incorporated culture in health promotion and health communication. We conclude by articulating yet unanswered questions and suggesting future directions to move the field forward. Expected final online publication date for the Annual Review of Public Health, Volume 45 is April 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Abstract
OBJECTIVES Although links between social relationships and health are well established, few studies have concurrently examined the effects of compositional, structural, and functional dimensions of social networks on glycemic (HbA1c) control in low- and middle-income countries such as Ghana. In these settings where informal social relationships are critical for access to resources, evaluating the links between social network characteristics, social support, and glycemic control may provide clarity about important relationships that facilitate the well-being of individuals with type 2 diabetes mellitus (T2DM). DESIGN In 2018, we conducted a hospital-based, cross-sectional survey of noninstitutionalized adults with T2DM in Ghana. Using data from 247 study participants, multivariable linear regression models were used to estimate associations between: 1) HbA1c and three social network characteristics (kin composition, household composition, and network density); 2) social support and the three social network characteristics; and 3) HbA1c and social support. We also examined gender differences in these associations and applied mediation techniques to determine if network characteristics operated through social support to affect HbA1c. RESULTS Findings indicated that higher kin composition and higher household composition were each significantly associated with increased social support. Neither social support nor social network characteristics were significantly related to HbA1c, and there were no gender differences in any of these associations. CONCLUSION Although family and household members were identified as important sources of social support for diabetes management, the ways in which they influence HbA1c control among Ghanaians require further investigation. Future studies can examine whether changes in social support over time, social support satisfaction, or other dimensions of social relationships improve T2DM outcomes in countries like Ghana.

Abstract
Few studies have compared the effects of different front-of-package label (FOPL) systems in the 'real world'. This study assessed adults' awareness, use and understanding of nutrition facts labels (NFLs) and nationally implemented FOPLs such as Health Star Ratings (HSR), Traffic lights, and Guideline Daily Amounts (GDAs) in five countries, including before and after implementation of Mexico's warning FOPLs in 2020. Data were from the International Food Policy Study, an annual repeat cross-sectional study conducted in 2018-2020 among adults (N=64,032) in Australia, Canada, Mexico, the UK and the US. Self-reported awareness, use, and understanding of NFLs (in all five countries) and FOPLs (in Australia, Mexico, and UK) were assessed over time, between countries, and between NFLs and FOPLs. Most respondents in all countries reported seeing their country's NFLs (awareness) 'often' or 'all the time' across all three years, with one third to half of respondents using NFLs 'often' or 'all the time' (Australia: 43-45%; Canada: 47-50%; Mexico: 36-39%; UK: 32-34%; US: 47-49%), and approximately one half to two thirds finding NFLs 'easy' or 'very easy to understand' (56-57%; 67-69%; 51-54%; 48-51%; 70-71%). In 2020, awareness, use and self-reported understanding of the Warning FOPLs in Mexico were highest among all countries with a FOPL (p<0.001), whereas awareness and use were lowest for Australia's HSR (p<0.001). In countries with FOPLs, self-reported understanding was higher for FOPLs than NFLs, except for the GDA FOPL in Mexico. Only modest changes were observed over time. Warning FOPLs were associated with greater levels of self-reported awareness, use and understanding among adults compared to NFLs and GDA-based FOPLs. FOPLs implemented on a voluntary basis, such as Australia's HSR, may be less likely to be seen and used.

Abstract
INTRODUCTION The need for quantitative criteria to appraise the quality of implementation research has recently been highlighted to improve methodological rigour. The Implementation Science Research development (ImpRes) tool and supplementary guide provide methodological guidance and recommendations on how to design high-quality implementation research. This protocol reports on the development of the Implementation Science Research Project Appraisal Criteria (ImpResPAC) tool, a quantitative appraisal tool, developed based on the structure and content of the ImpRes tool and supplementary guide, to evaluate the conceptual and methodological quality of implementation research. METHODS AND ANALYSIS This study employs a three-stage sequential mixed-methods design. During stage 1, the research team will map core domains of the ImpRes tool, guidance and recommendations contained in the supplementary guide and within the literature, to ImpResPAC. In stage 2, an international multidisciplinary expert group, recruited through purposive sampling, will inform the refinement of ImpResPAC, including content, scoring system and user instructions. In stage 3, an extensive psychometric evaluation of ImpResPAC, that was created in stage 1 and refined in stage 2, will be conducted. The scaling assumptions (inter-item and item-total correlations), reliability (internal consistency, inter-rater) and validity (construct and convergent validity) will be investigated by applying ImpResPAC to 50 protocols published in Implementation Science. We envisage developing ImpResPAC in this way will provide implementation research stakeholders, primarily grant reviewers and educators, a comprehensive, transparent and fair appraisal of the conceptual and methodological quality of implementation research, increasing the likelihood of funding research that will generate knowledge and contribute to the advancement of the field. ETHICS AND DISSEMINATION This study will involve human participants. This study has been registered and minimal risk ethical clearance granted by The Research Ethics Office, King's College London (reference number MRA-20/21-20807). Participants will receive written information on the study via email and will provide e-consent if they wish to participate. We will use traditional academic modalities of dissemination (eg, conferences and publications).

Abstract
INTRODUCTION Postpartum depression (PPD) affects around one in seven women globally, with these women in need of non-pharmaceutical treatment strategies. There is a long history of the benefits of singing for maternal mental health, and promising research exists showing the clinical effectiveness of group singing. Group singing interventions are being scaled up to support new mothers in the United Kingdom, but we do not know if such an intervention may benefit women in different cultural contexts. This protocol focuses on exploring the feasibility of implementation and perceived impact of a 10-week group singing intervention for new mothers in Romania and Denmark eliciting signs of PPD. METHODS AND ANALYSIS Data will be collected from up to 48 women with a score ≥10 on the Edinburgh Postnatal Depression Scale (EPDS) participating in a 10-week group singing intervention in Denmark or Romania, as well as a range of project stakeholders. The singing classes will take place in person and be facilitated by professional singing leaders. Feasibility of implementation will be analysed through qualitative data (eg, focus groups, interviews) and quantitative data (eg, the Feasibility of Intervention Measure). Perceived impact will be explored via surveys that include mental health measures (EPDS, Multidimensional Scale of Perceived Social Support, WHO Five Well-Being Index) from singing intervention participants (at weeks 1, 6, 10) and focus groups. Descriptive statistics, repeated measures analysis of variance and analysis of covariance will be used to analyse quantitative data. Framework method and thematic analysis will be used to analyse qualitative data. ETHICS AND DISSEMINATION The national ethics committees in Romania (IRB-PH Protocol #2021-211217-012) and Denmark (case number 1-10-72-274-21) have approved the study, as has the Ethics Review Committee at the World Health Organization (ERC.0003714). All participants will be required to provide informed consent. Results will be disseminated by reports published by the WHO Regional Office for Europe, peer-reviewed publications and at conferences.

Abstract
Lumateperone is a novel drug approved for the treatment of schizophrenia in adults and depressive episodes associated with bipolar depression in adults, as monotherapy and as adjunctive therapy with lithium or valproate treatment in the United States. Lumateperone simultaneously modulates key neurotransmitters, such as serotonin, dopamine, and glutamate, implicated in serious mental illness. In patients with schizophrenia, lumateperone was shown to improve positive symptoms along with negative and depressive symptoms, while also enhancing prosocial behavior. Moreover, in patients with bipolar I or II disorder, lumateperone improved depressive symptoms as well. To further understand the mechanisms related to lumateperone's clinical response, the aim of this study was to investigate the effect of lumateperone on dopaminergic- and glutamatergic signaling in the rat medial prefrontal cortex (mPFC). We used the conditioned avoidance response (CAR) test to determine the antipsychotic-like effect of lumateperone, electrophysiology in vitro to study lumateperone's effects on NMDA- and AMPA-induced currents in the mPFC, and the neurochemical techniques microdialysis and amperometry to measure dopamine- and glutamate release in the rat mPFC. Our results demonstrate that lumateperone; i) significantly suppressed CAR in rats, indicating an antipsychotic-like effect, ii) facilitated NMDA and AMPA receptor-mediated currents in the mPFC, in a dopamine D1-dependent manner, and iii) significantly increased dopamine and glutamate release in the rat mPFC. To the extent that these findings can be translated to humans, the ability of lumateperone to activate these pathways may contribute to its demonstrated effectiveness in safely improving symptoms related to neuropsychiatric disorder including mood alterations.

Abstract
This study examined whether the frequency of participation in religious activities and seeking care from spiritual and other traditional medicine (TM) practitioners were associated with blood glucose (HbA1c) control among urban Ghanaians with type 2 diabetes mellitus (T2DM). Findings revealed that increased frequency of participation in religious activities was significantly associated with decreased HbA1c levels, whereas increased use of TM practitioners was significantly associated with increased HbA1c levels. These findings suggest that strategically integrating religious activities into disease management plans for Ghanaians with T2DM who identify as being religious may be a viable intervention mechanism.

Abstract
Recent research has indicated that religiosity has multiple dimensions and that religious self-regulation may be a more effective predictor of intimate partner violence (IPV) perpetration than other measures of religiosity, such as frequency of prayer or church attendance. Nonetheless, studies have produced inconsistent results regarding the associations between religious self-regulation and IPV perpetration. Moreover, no studies have included self-reported level of religiosity in addition to religious self-regulation in predictive models of IPV perpetration. The present study sought to address the following research question: What is the association between religious self-regulation and men's IPV perpetration, accounting for self-reported level of religiosity? A convenience sample of 289 men, who had been in their current committed heterosexual relationship for at least one year, were recruited via Amazon's Mechanical Turk and responded to an online survey. Logistic and negative binomial regression analyses indicated that introjected religious self-regulation was significantly positively associated with physical, psychological, and sexual IPV perpetration, while identified religious self-regulation was significantly negatively associated with physical, psychological, and sexual IPV perpetration, supporting both hypotheses. These findings have implications for faith leaders and secular service providers seeking to develop effective, culturally sensitive, and empirically informed IPV intervention and prevention strategies.

Abstract
BACKGROUND Stigma is a formidable burden for survivors of lung cancer that can reduce the quality of life (QOL), resulting in physical, social and psychological challenges. This study investigates associations between stigma and depression, QOL and demographic and health-related characteristics, including race. DESIGN An adapted conceptual model derived from the Cataldo Lung Cancer Stigma Scale guided this descriptive correlation study assessing stigma in African American and Caucasian survivors of lung cancer. Self-reported, written surveys measuring depression, QOL, lung cancer stigma and demographics were administered. Statistical analysis was conducted to assess associations between stigma and depression, stigma and QOL and stigma and race, while adjusting for demographic characteristics. RESULTS Participants (N = 56) included 30 Caucasian and 26 African American survivors of lung cancer recruited from a cancer registry of an American College of Surgeons-accredited programme, a survivors' support club and an ambulatory oncology practice in the southeastern United States. Statistical analysis yielded (1) a significant moderate positive association between depression and lung cancer stigma; (2) a significant moderate negative association between QOL and lung cancer stigma; and (3) significant relationships between race and lung cancer stigma, specifically higher degree of stigma among African Americans compared to Caucasians. CONCLUSION Stigma affects many aspects of survivors' lives. Healthcare professionals need to consider how health-related stigma may further complicate the physical burdens, psychological distresses and social challenges that accompany the disease, especially among African American survivors. Additional enquiry and interventions are needed to assist with mitigating the negative effects of stigma on survivors and their family members and friends. PATIENT OR PUBLIC CONTRIBUTION Fifty-six survivors of lung cancer participated in this descriptivecorrelation study. They completed written surveys measuring depression, QOL, and lung cancer stigma, plus an investigator-developed demographic information form.

Abstract
INTRODUCTION Stroke survivors, once in the community, face challenges with their long-term rehabilitation care and present higher levels of loneliness, depression and anxiety than the rest of the population. A community-based performance arts programme, Stroke Odysseys (SO), has been devised to tackle the challenges of living with stroke in the UK. In this study, we aim to evaluate the implementation, impact and experiences of SO for stroke survivors. METHODS AND ANALYSIS Scaling-up Health Arts Programmes: Implementation and Effectiveness Research (SHAPER)-SO aims to scale-up SO to 75 participants and 47 stakeholders, while simultaneously evaluating the effectiveness and implementation of the programme. The main research aim is to evaluate the implementation, effectiveness, impact and experiences of a community-based performance arts programme (SO for stroke survivors). This mixed-methods study will evaluate the experience and impact of SO on those participating using mixed methods (interviews, observations and surveys) before and after each stage and carry out non-participant observations during a percentage of the workshops, training and tour. Data will be analysed using quantitative and qualitative approaches. This is a study within the SHAPER programme. ETHICS AND DISSEMINATION Ethical approval has been granted by the King's College London PNM Research Ethics Panel, REC reference: LRS/DP-20/21-21549. Written informed consent will be sought for participants and stakeholders. The results of the study will be reported and disseminated at international conferences and in peer-reviewed scientific journals. TRIAL REGISTRATION NUMBER NCT04864470.

Abstract
INTRODUCTION Research on the benefits of 'arts' interventions to improve individuals' physical, social and psychological well-being is growing, but evidence on implementation and scale-up into health and social care systems is lacking. This protocol reports the SHAPER-Implement programme (Scale-up of Health-Arts Programmes Effectiveness-Implementation Research), aimed at studying the impact, implementation and scale-up of: Melodies for Mums (M4M), a singing intervention for postnatal depression; and Dance for Parkinson's (PD-Ballet) a dance intervention for Parkinson's disease. We examine how they could be embedded in clinical pathways to ensure their longer-term sustainability. METHODS AND ANALYSIS A randomised two-arm effectiveness-implementation hybrid type 2 trial design will be used across M4M/PD-Ballet. We will assess the implementation in both study arms (intervention vs control), and the cost-effectiveness of implementation. The design and measures, informed by literature and previous research by the study team, were refined through stakeholder engagement. Participants (400 in M4M; 160 in PD-Ballet) will be recruited to the intervention or control group (2:1 ratio). Further implementation data will be collected from stakeholders involved in referring to, delivering or supporting M4M/PD-Ballet (N=25-30 for each intervention).A mixed-methods approach (surveys and semi-structured interviews) will be employed. 'Acceptability' (measured by the 'Acceptability Intervention Measure') is the primary implementation endpoint for M4M/PD-Ballet. Relationships between clinical and implementation outcomes, implementation strategies (eg, training) and outcomes will be explored using generalised linear mixed models. Qualitative data will assess factors affecting the acceptability, feasibility and appropriateness of M4M/PD-Ballet, implementation strategies and longer-term sustainability. Costs associated with implementation and future scale-up will be estimated. ETHICS AND DISSEMINATION SHAPER-PND (the M4M trial) and SHAPER-PD (the PD trial) are approved by the West London and GTAC (20/PR/0813) and the HRA and Health and Care Research Wales (REC Reference: 20/WA/0261) Research Ethics Committees. Study findings will be disseminated through scientific peer-reviewed journals and scientific conferences.

Abstract
INTRODUCTION Postnatal depression (PND) affects approximately 13% of new mothers. Community-based activities are sought after by many mothers, especially mothers that prefer not to access pharmacological or psychological interventions. Singing has shown positive effects in maternal mood and mother-child bonding. The Scaling-Up Health-Arts Programmes: Implementation and Effectiveness Research-Postnatal Depression study will analyse the clinical and implementation effectiveness of 10-week singing sessions for PND in new mothers. This protocol paper will focus on the clinical effectiveness of this trial. METHODS AND ANALYSIS A total of 400 mothers with PND (with a score of at least 10 on the Edinburgh Postnatal Depression Scale) and their babies will be recruited for this hybrid type II randomised controlled trial. The intervention group will attend 10 weekly singing sessions held at community venues or online, facilitated by the arts organisation, Breathe Arts Health Research (Breathe). A control group will be encouraged to attend non-singing sessions in the community or online for 10 weeks. A package of assessments will be collected from participants for clinical, mechanistic and implementation outcomes, at different stages of the trial. Clinical assessments will include questionnaires and interviews for demographics, mental health and social measures, together with biological samples for measurement of stress markers; the study visits are at baseline, week 6 (mid-trial) and week 10 (end of trial), with follow ups at weeks 20 and 36. Multiple imputation will be used to deal with possible missing data and multivariable models will be fitted to assess differences between groups in the outcomes of the study. ETHICS AND DISSEMINATION Ethical approval has been granted by the London-West London and GTAC Research Ethics Committee, REC reference: 20/PR/0813. TRIAL REGISTRATION NUMBER NCT04834622; Pre-results.

Abstract
Vasectomy is one of the few options men have to manage their reproductive capacity and take on a more equitable role in pregnancy prevention. While the method is underused throughout the United States, the southern states have a lower prevalence rate compared to the rest of the country. Existing survey research does not assess what men know or think about the procedure as a means of understanding why this is the case. We created and conducted an exploratory survey to assess men’s knowledge, attitudes, and information-seeking behaviors about vasectomy in the Southern United States. We used targeted Facebook advertising to recruit men ages 25–70 years living in 7 southern states to complete an online survey (n = 397). Using regression analyses, we identify that participants who had a vasectomy knew more about the procedure than participants who had not. Participants who had not had a vasectomy had less positive attitudes about the procedure across all six attitude subscales compared to participants with vasectomies. We highlight potential avenues for future research to understand why this may be the case. Finally, the majority of participants knew someone who had had a vasectomy. This suggests that men disclose having a vasectomy to others. The interpersonal dynamics around vasectomy decision-making and disclosure remain unknown and a viable area for future research. Findings from this exploratory survey may be used by public health officials interested in implementing campaigns to increase knowledge about vasectomy and reduce stigma, which may encourage more positive attitudes about the procedure.

Abstract
OBJECTIVES Measuring staff perspectives on patient safety culture (PSC) can identify areas of concern that, if addressed, could lead to improvements in healthcare. To date, there is no validated measure to assess PSC that has been tested and adapted for use in Bosnia and Herzegovina (BiH). This research addresses the gap in the evidence through the psychometric assessment of the Agency for Healthcare Research and Quality's: 'Hospital Survey on Patient Safety Culture' (HSOPSC), to determine its suitability for the health system in BiH. SETTING Nine hospitals. PARTICIPANTS Healthcare professionals (n=1429); nurse (n=823), doctors (n=328), other clinical personnel (n=111), non-clinical personnel (n=60), other (n=64), no response (n=43). PRIMARY AND SECONDARY OUTCOME MEASURES A translated version of HSOPSC was used to conduct psychometric evaluation including exploratory factor analysis and confirmatory factor analysis (CFA). Comparison between the original HSOPSC and the newly adapted 'Hospital Survey on Patient Safety Culture for Bosnia and Herzegovina' (HSOPSC-BiH) was carried out. RESULTS Compared with the original survey, which has 12 factors (42 items), the adapted survey consisted of 9 factors (29 items). The following factors from the original survey were not included in their original form: Communication Openness, Feedback and Communications about error, Overall Perceptions of Patient Safety and Organisational learning-Continuous Improvement. The results of the CFA for HSOPSC-BiH showed a better model fit compared with the original HSOPSC. The absolute and relative fit indices showed excellent model adjustment. CONCLUSIONS The BiH version of Hospital Survey on Patient Safety Culture demonstrated satisfactory psychometric properties, with acceptable to good internal consistency and construct validity. Therefore, we recommend the HSOPSC-BiH as a basis for assessing PSC in BiH. This survey could provide insight into patient safety concerns in BiH so that strategies to overcome these issues could be formulated and implemented.

Abstract
IMPORTANCE Approximately 38% of patients with advanced colorectal cancer do not receive chemotherapy. OBJECTIVE To determine whether cumulative social risk (ie, multiple co-occurring sociodemographic risk factors) is associated with lower receipt of chemotherapy among patients with advanced colorectal cancer and whether social support would moderate this association. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional, population-based, mailed survey study was conducted from 2012 to 2014. Participants were recruited between 2011 and 2014 from all adults within 1 year after diagnosis of stage III colorectal cancer in the Detroit, Michigan, and State of Georgia Surveillance, Epidemiology, End-Results cancer registries. Patients were eligible if they were aged 18 years or older, had undergone surgery 4 or more months ago, did not have stage IV cancer, and resided in the registry catchment areas. Data analyses were conducted from March 2017 to April 2021. MAIN OUTCOMES AND MEASURES The primary outcome was receipt of chemotherapy. Cumulative social risk represented a sum of 8 risk factors with the potential to drain resources from participants' cancer treatment (marital status, employment, annual income, health insurance, comorbidities, health literacy, adult caregiving, and perceived discrimination). Social support was operationalized as emotional support related to colorectal cancer diagnosis. RESULTS Surveys were mailed to 1909 eligible patients; 1301 completed the survey (response rate, 68%). A total of 1087 participants with complete data for key variables were included in the sample (503 women [46%]; mean [SD] age, 64 [13] years). Participants with 3 or more risk factors were less likely to receive chemotherapy than participants with 0 risk factors (3 factors, odds ratio [OR], 0.48 [95% CI, 0.26-0.87]; 4 factors, OR, 0.41 [95% CI, 0.21-0.78]; 5 factors, OR, 0.42 [95% CI, 0.20-0.87]; ≥6 factors, OR, 0.22 [95% CI, 0.09-0.55]). Participants with 2 or more support sources had higher odds of undergoing chemotherapy than those without social support (2 sources, OR, 3.05 [95% CI, 1.36-6.85]; 3 sources, OR, 3.24 [95% CI, 1.48-7.08]; 4 sources, OR, 3.69 [95% CI, 1.71-7.97]; 5 sources, OR, 4.40 [95% CI, 1.98-9.75]; ≥6 sources, OR 5.95 [95% CI, 2.58-13.74]). Within each social support level, participants were less likely to receive chemotherapy as cumulative social risk increased. CONCLUSIONS AND RELEVANCE Cumulative social risk was associated with reduced receipt of chemotherapy. These associations were mitigated by social support. Assessing cumulative social risk may identify patients with colorectal cancer who are at higher risk for omitting chemotherapy who can be targeted for support programs to address social disadvantage and increase social support.

Abstract
DNA polymerase theta (POLθ) is synthetic lethal with Homologous Recombination (HR) deficiency and thus a candidate target for HR-deficient cancers. Through high-throughput small molecule screens we identified the antibiotic Novobiocin (NVB) as a specific POLθ inhibitor that selectively kills HR-deficient tumor cells in vitro and in vivo. NVB directly binds to the POLθ ATPase domain, inhibits its ATPase activity, and phenocopies POLθ depletion. NVB kills HR-deficient breast and ovarian tumors in GEMM, xenograft and PDX models. Increased POLθ levels predict NVB sensitivity, and BRCA-deficient tumor cells with acquired resistance to PARP inhibitors (PARPi) are sensitive to NVB in vitro and in vivo. Mechanistically, NVB-mediated cell death in PARPi-resistant cells arises from increased double-strand break end resection, leading to accumulation of single-strand DNA intermediates and non-functional RAD51 foci. Our results demonstrate that NVB may be useful alone or in combination with PARPi in treating HR-deficient tumors, including those with acquired PARPi resistance. (151/150).

Abstract
The 90 kDa heat shock protein (Hsp90) is a molecular chaperone that processes nascent polypeptides into their biologically active conformations. Many of these proteins contribute to the progression of cancer, and consequently, inhibition of the Hsp90 protein folding machinery represents an innovative approach toward cancer chemotherapy. However, clinical trials with Hsp90 N-terminal inhibitors have encountered deleterious side effects and toxicities, which appear to result from the pan-inhibition of all four Hsp90 isoforms. Therefore, the development of isoform-selective Hsp90 inhibitors is sought to delineate the pathological role played by each isoform. Herein, we describe a structure-based approach that was used to design the first Hsp90α-selective inhibitors, which exhibit >50-fold selectivity versus other Hsp90 isoforms.

Abstract
Objective We applied a social network approach to examine if three types of diabetes-related stigma (self-stigma, perceived stigma and enacted stigma) moderated associations between social network characteristics (network size, kin composition, household composition, and network density), social support, and blood glucose among Ghanaians with type 2 diabetes mellitus (T2DM). Methods Data were obtained through a cross-sectional survey of 254 adults at a diabetes clinic in Ghana that assessed participants' social networks, social support, and frequency of experiencing three types of diabetes-related stigma. Results Self-stigma moderated associations between kin composition and social support when controlling for network size β=-.97, P=.004). Among study participants reporting low self-stigma, kin composition was positively associated with social support (β=1.29, P<.0001), but this association was not found among those reporting high self-stigma. Network size was positively associated with social support among participants reporting both low and high self-stigma. None of the types of diabetes-related stigma moderated other associations between social networks, social support, and blood glucose. Conclusions Individuals with T2DM who report high self-stigma may have lower social support, which can reduce their capacity for disease management. Additionally, larger social networks may be beneficial for individuals with T2DM in countries like Ghana, and interventions that expand network resources may facilitate diabetes control.

Abstract
BACKGROUND There is now a rising commitment to acknowledge the role patients and families play in contributing to their safety. This review focuses on one type of involvement in safety - patient and family involvement in escalation of care for serious life-threatening conditions i.e. helping secure a step-up to urgent or emergency care - which has been receiving increasing policy and practice attention. This review was concerned with the negotiation work that patient and family members undertake across the emergency care escalation pathway, once contact has been made with healthcare staff. It includes interventions aiming to improve detection of symptoms, communication of concerns and staff response to these concerns. OBJECTIVES To assess the effects of interventions designed to increase patient and family involvement in escalation of care for acute life-threatening illness on patient and family outcomes, treatment outcomes, clinical outcomes, patient and family experience and adverse events. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL, MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP) ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform from 1 Jan 2000 to 24 August 2018. The search was updated on 21 October 2019. SELECTION CRITERIA We included randomised controlled trials (RCTs) and cluster-randomised controlled trials where the intervention focused on patients and families working with healthcare professionals to ensure care received for acute deterioration was timely and appropriate. A key criterion was to include an interactive element of rehearsal, role play, modelling, shared language, group work etc. to the intervention to help patients and families have agency in the process of escalation of care. The interventions included components such as enabling patients and families to detect changes in patients' conditions and to speak up about these changes to staff. We also included studies where the intervention included a component targeted at enabling staff response. DATA COLLECTION AND ANALYSIS Seven of the eight authors were involved in screening; two review authors independently extracted data and assessed the risk of bias of included studies, with any disagreements resolved by discussion to reach consensus. Primary outcomes included patient and family outcomes, treatment outcomes, clinical outcomes, patient and family experience and adverse events. Our advisory group (four users and four providers) ensured that the review was of relevance and could inform policy and practice. MAIN RESULTS We included nine studies involving 436,684 patients and family members and one ongoing study. The published studies focused on patients with specific conditions such as coronary artery disease, ischaemic stroke, and asthma, as well as pregnant women, inpatients on medical surgical wards, older adults and high-risk patients with a history of poor self-management. While all studies tested interventions versus usual care, for four studies the usual care group also received educational or information strategies. Seven of the interventions involved face-to-face, interactional education/coaching sessions aimed at patients/families while two provided multi-component education programmes which included components targeted at staff as well as patients/families. All of the interventions included: (1) an educational component about the acute condition and preparedness for future events such as stroke or change in fetal movements: (2) an engagement element (self-monitoring, action plans); while two additionally focused on shared language or communication skills. We had concerns about risk of bias for all but one of the included studies in respect of one or more criteria, particularly regarding blinding of participants and personnel. Our confidence in results regarding the effectiveness of interventions was moderate to low. Low-certainty evidence suggests that there may be moderate improvement in patients' knowledge of acute life-threatening conditions, danger signs, appropriate care-seeking responses, and preparedness capacity between interactional patient-facing interventions and multi-component programmes and usual care at 12 months (MD 4.20, 95% CI 2.44 to 5.97, 2 studies, 687 participants). Four studies in total assessed knowledge (3,086 participants) but we were unable to include two other studies in the pooled analysis due to differences in the way outcome measures were reported. One found no improvement in knowledge but higher symptom preparedness at 12 months. The other study found an improvement in patients' knowledge about symptoms and appropriate care-seeking responses in the intervention group at 18 months compared with usual care. Low-certainty evidence from two studies, each using a different measure, meant that we were unable to determine the effects of patient-based interventions on self-efficacy. Self-efficacy was higher in the intervention group in one study but there was no difference in the other compared with usual care. We are uncertain whether interactional patient-facing and multi-component programmes improve time from the start of patient symptoms to treatment due to low-certainty evidence for this outcome. We were unable to combine the data due to differences in outcome measures. Three studies found that arrival times or prehospital delay time was no different between groups. One found that delay time was shorter in the intervention group. Moderate-certainty evidence suggests that multi-component interventions probably have little or no impact on mortality rates. Only one study on a pregnant population was eligible for inclusion in the review, which found no difference between groups in rates of stillbirth. In terms of unintended events, we found that interactional patient-facing interventions to increase patient and family involvement in escalation of care probably have few adverse effects on patient's anxiety levels (moderate-certainty evidence). None of the studies measured or reported patient and family perceptions of involvement in escalation of care or patient and family experience of patient care. Reported outcomes related to healthcare professionals were also not reported in any studies. AUTHORS' CONCLUSIONS Our review identified that interactional patient-facing interventions and multi-component programmes (including staff) to increase patient and family involvement in escalation of care for acute life-threatening illness may improve patient and family knowledge about danger signs and care-seeking responses, and probably have few adverse effects on patient's anxiety levels when compared to usual care. Multi-component interventions probably have little impact on mortality rates. Further high-quality trials are required using multi-component interventions and a focus on relational elements of care. Cognitive and behavioural outcomes should be included at patient and staff level.

Abstract
OBJECTIVE Venous thromboembolism (VTE) is a potentially fatal complication of hospitalisation. Intermittent pneumatic compression (IPC) is one approach to reducing the likelihood of a VTE. Adherence to IPC is known to be inadequate though the reasons for this remain unclear. This systematic review explores factors that affect adherence to IPC in the inpatient context. METHODS Information sources-EMBASE, MEDLINE and PsycINFO were searched for literature between January 1960 and May 2019. Eligibility criteria-studies were included if they focused on inpatient care and examined factors affecting adherence to IPC devices. RESULTS Included studies-a total of 20 out of 1476 studies were included. Synthesis of results-eight factors were identified that affected adherence: patient discomfort (n=8), healthcare professionals' knowledge and behaviours (n=6), mobilisation (n=6), equipment supply and demand (n=3), the use of guidelines (n=3), intensive care context (n=2), computer-assisted prescribing (n=2) and patients' knowledge of IPC (n=1). CONCLUSION Overall while the evidence base is quite limited, a number of factors were shown to affect adherence to IPC. These findings could be used to inform future research and quality improvement efforts to increase adherence in this very important, but currently under-researched area.

Abstract
BACKGROUND Social support, which is partly emotional support, is associated with adherence to colorectal cancer (CRC) treatment, quality of life, and survival. We hypothesized that the needs, sources, and availability of emotional support would vary by race and income among CRC patients and sought to quantify the emotional support and the perceived adequacy of support reported by patients. METHODS We surveyed CRC patients from Detroit and Georgia Surveillance, Epidemiology and End Results registries about the quantity and quality of emotional support received from different sources. We tested differences using the chi-square test, t-tests, and logistic regression. RESULTS There were 1909 patients who met inclusion criteria and 1301 (68%) completed surveys. Among respondents, 68% were white, 25% black, and 7% other. Black patients were more likely to be female and younger and reported lower annual income and education. Patients reported high support from several sources. Among those with a spouse/partner (58%), 95% reported high levels of support; however, older, black, female, or lower income patients were less likely to have spouses/partners (P < .001). Patients also endorsed high support from family (88.6%), important others (82.9%), and clinicians (71.3%). Black patients were less likely than white patients to report support that was "just right" (P < .001). DISCUSSION Most patients reported high emotional support from at least 1 source. Black patients were most at risk for low support or unmet support needs. Spouse/partner support was important but only available to 58% of respondents. Patients at risk for unmet emotional support needs may benefit from additional support resources.

Abstract
Objectives: Conversations about pictorial cigarette health warning labels (HWLs) encourage quit attempts, and prior research suggests prevalence of these conversations varies by ethnicity. We assessed the frequency of conversations about text-only HWLs among Latino and non-Latino white smokers and the relationship between conversations and subsequent quit attempts. Methods: Latino and non-Latino white adult smokers in the United States (N = 4403) were surveyed every 4 months over 2 years. Surveys queried smoking behaviors, recent quit attempts, HWL responses, including HWL conversations, and socio-demographic variables. Negative binomial generalized estimating equation (GEE) models regressed the frequency of HWL conversations on study variables. Logistic GEE models regressed quit attempts at follow-up surveys on responses from the prior wave, including frequency of HWL conversations and their interaction with ethnicity. Results: Spanish preference Latinos reported the most HWL conversations (85%), followed by English preference Latinos (59%), and non-Latino Whites (35%). More frequent HWL conversations predicted subsequent quit attempts (AOR = 1.74, 95% CI = 1.32, 2.30), but ethnicity did not moderate this effect. Conclusions: Latinos appear to talk more frequently about HWLs than non-Latino Whites but are no more likely to quit as a result. Cessation campaigns should use messages that encourage conversations about quitting.

Abstract
OBJECTIVE We examined the perspectives of child and family-serving professionals (CFSP) and state policymakers on protective factors to develop policy and program recommendations including current and needed approaches for addressing ACEs. METHODS In 2018, we conducted semi-structured, in-depth interviews with 23 CFSP and 24 state policymakers in South Carolina. Data were analyzed applying the Multiple Streams Theory using thematic analyses. RESULTS CFSPs and policymakers had varying opinions on state government involvement and primary prevention for ACEs. Three protective factors emerged from their perspectives: 1) loving, trusting, and nurturing relationships; 2) safe home environments; and 3) opportunities to thrive. For each of these protective factors, participants suggested policy options that support existing community efforts, attempt to alleviate poverty, and improve child and family serving systems. CONCLUSION This study suggests that CFSPs and policymakers recognize the importance of protective factors in a child's life to buffer the effect of ACEs. More awareness is needed about the feasibility and significance of primary prevention of ACEs. The study's findings can be used to strengthen advocacy priorities for a wide range of public health outcomes associated with ACEs and help further bridge the gap between research and policy.

Abstract
Acquiescence is often defined as the systematic selection of agreeable ("strongly agree") or affirmative ("yes") responses to survey items, regardless of item content or directionality. This definition implies that acquiescence is immune to item characteristics; however, the influence of item characteristics on acquiescence remains largely unexplored. We examined the influence of eight item characteristics on acquiescence in a telephone survey of 400 Latinos and non-Latino whites: qualified wording, mental comparisons, negated wording, unfamiliar terms, ambiguous wording, knowledge accessibility, item length, and polysyllabic wording. Negated and ambiguous wording was associated with reduced acquiescence for the full sample, as well as subsamples stratified by ethnicity and sociodemographic characteristics. This effect was strongest among younger, more educated, and non-Latino white respondents. No other item characteristics had a significant influence on respondent acquiescence. Findings from this study suggest that acquiescence may be affected by interactions between respondent and item characteristics.

Abstract
The development of C-terminal heat shock protein 90 kDa (Hsp90) inhibitors has emerged as a potential treatment for cancer. Similarly, small molecules that target the mitochondria have proven to be efficacious towards cancer, as the reprogramming of mitochondrial function is often associated with oncogenic transformation. Herein, we report the development of triphenylphosphonium (TPP)-conjugated Hsp90 C-terminal inhibitors, their anti-proliferative activity, and accumulation in the mitochondria. In general, TPP-conjugated Hsp90 C-terminal inhibitors were found to manifest increased activity against various cancer cell lines when compared to the parent compounds.

Abstract
Objectives. To examine measurement comparability of a Spanish version of self-rated health (SRH) with pasable as an alternative to regular for the response category "fair" in the English version.Methods. We translated "fair" into 2 Spanish versions: regular and pasable. We implemented a split-half experiment in 3 surveys independently conducted from October 2015 to January 2016, from April to November 2016, and from August to November 2017. Within each survey, we randomly assigned Spanish-interviewed Latino respondents to 1 of the 2 SRH versions. The total sample included 3261 Latino and 738 non-Latino White adults in the United States.Results. Spanish-interviewed Latinos reported substantively more favorable health on SRH with pasable than with regular. When pasable instead of regular was used for SRH, we observed a larger difference between respondents reporting positive versus negative SRH on objective health measures, including the frequency of doctor's visits. Furthermore, when we accounted for correlates of health, Latino-White disparities were attenuated with pasable.Conclusions. We recommend using pasable instead of regular for SRH Spanish translations to improve measurement equivalence in cross-lingual and cross-cultural research.

Abstract
PURPOSE As adverse childhood experiences (ACEs) become increasingly recognized as a root cause of unhealthy behaviors, researchers, practitioners, and legislators seek to understand policy strategies to prevent and mitigate its effects. Given the high prevalence of ACEs, policies that address ACEs can meaningfully prevent disease in adulthood and improve population health. We sought to understand barriers and opportunities for policies to prevent and mitigate ACEs by exploring state legislator perspectives. SETTING AND PARTICIPANTS Twenty-four current state legislators in South Carolina. DESIGN In 2018, we conducted semistructured interviews with 24 state legislators. Participants were recruited using maximum variation sampling. The researchers individually analyzed each interview transcript using focused coding qualitative techniques. A high inter-rater agreement was demonstrated (κ = .76 to .87), and discrepancies were resolved through discussion. METHOD The data collection and analysis were guided by Multiple Streams Theory, which identifies 3 key components (attention to the problem, decisions about policy options, and the impact of political landscape) that can lead windows of opportunity for passing policies. RESULTS Legislators identified several factors that can influence the passage of legislation on ACEs: awareness of ACEs; gaps in understanding about what can be done about ACEs; the use of data and stories that contextualize the problem of ACEs; capitalizing on the bipartisanship of children's issues; and linking to current ACEs-related issues on the policy agenda, such as school safety and violence prevention and the opioid epidemic. CONCLUSION Public health researchers and practitioners should focus on the factors identified to advocate for policies that prevent ACEs and/or address their health consequences.

Abstract
PROBLEM IDENTIFICATION Lung cancer survivors face many challenges that affect their quality of life and survival. A growing concern is the layered effect of stigma related to cigarette smoking and the perceived life-threatening diagnosis of lung cancer. This experience may affect lung cancer survivors' physical, psychological, and social well-being, negatively influencing their quality of life. LITERATURE SEARCH CINAHL®, PubMed®, PsycINFO®, and Web of Science were searched from January 2000 through August 2017, using combinations of four keywords. DATA EVALUATION Extracted data included research aims, design, method, analytical approach, sample size, gender, ethnicity/race, setting, stigma measure, smoking status, and major results. SYNTHESIS Of 163 studies initially identified, 30 (19 quantitative, 8 qualitative, 2 theoretical reviews, and 1 mixed method) were included. Quantitative studies were analyzed by statistical significance and relevant findings. Thematic analysis was used to evaluate qualitative studies. IMPLICATIONS FOR RESEARCH Future research should focus on the development and testing of tailored and multilevel interventions to support the management of stigma and lessen the negative impact it has on quality of life, with special considerations for vulnerable subpopulations.

Abstract
Heat shock protein 90 (Hsp90) is a eukaryotic chaperone responsible for the folding and functional activation of numerous client proteins, many of which are oncoproteins. Thus, Hsp90 inhibition has been intensely pursued, resulting in the development of many potential Hsp90 inhibitors, not all of which are well-characterized. Hsp90 inhibitors not only abrogate its chaperone functions, but also could help us gain insight into the structure-function relationship of this chaperone. Here, using biochemical and cell-based assays along with isothermal titration calorimetry, we investigate KU-32, a derivative of the Hsp90 inhibitor novobiocin (NB), for its ability to modulate Hsp90 chaperone function. Although NB and KU-32 differ only slightly in structure, we found that upon binding, they induce completely opposite conformational changes in Hsp90. We observed that NB and KU-32 both bind to the C-terminal domain of Hsp90, but surprisingly, KU-32 stimulated the chaperone functions of Hsp90 via allosteric modulation of its N-terminal domain, responsible for the chaperone's ATPase activity. In vitro and in silico studies indicated that upon KU-32 binding, Hsp90 undergoes global structural changes leading to the formation of a "partially closed" intermediate that selectively binds ATP and increases ATPase activity. We also report that KU-32 promotes HeLa cell survival and enhances the refolding of an Hsp90 substrate inside the cell. This discovery explains the effectiveness of KU-32 analogs in the management of neuropathies and may facilitate the design of molecules that promote cell survival by enhancing Hsp90 chaperone function and reducing the load of misfolded proteins in cells.

Abstract
Personalismo may have a broad influence on the well-being of U.S. Latinos by shaping social networks, and, in turn, access to information and resources. However, research on personalismo is currently constrained by the lack of a psychometrically sound measure of this cultural construct. This research used a mixed methods approach to develop a personalismo scale across three studies: a cognitive interviewing study with Mexican American adults (n=33); a cognitive interviewing study with non-Latino white, Mexican American, Puerto Rican, and Cuban American adults (n=61); and a psychometric telephone survey with Mexican American, Puerto Rican, and Cuban American adults (n=1,296). The final, 12-item scale had high internal consistency reliability and appears to be appropriate for use with Mexican American, Puerto Rican, and Cuban American adults. Significant differences emerged across Latino subgroups, with higher personalismo observed among Cuban Americans and female respondents, providing empirical evidence of cultural heterogeneity among U.S. Latino populations.

Abstract
Research indicates that Latino survey respondents are more likely to acquiesce than non-Latino European Americans, thereby decreasing the potential for measurement invariance across cultural groups. In order to better understand what drives this culturally patterned response style, we examined the influence of respondent and interviewer characteristics on acquiescence. Data were obtained from a telephone survey of 400 Mexican American, Puerto Rican, Cuban American, and non-Latino European American respondents and a self-administered survey of 21 interviewers. Higher acquiescence was associated with several respondent characteristics: older age, lower education, stronger Latino cultural orientation, Spanish use, Latino ethnicity, and, among Latinos, Cuban American ethnicity. In contrast, acquiescence was not influenced by respondent-interviewer social distance, social deference, or interviewer characteristics (e.g., education, gender, acculturation, interviewer experience). These findings indicate that acquiescence differs across Latino ethnic subgroups and that respondent and language factors are more influential determinants of acquiescence than survey interviewers.

Abstract
This study described experiences of caregivers of persons with Alzheimer's disease and other dementias (ADRD) and caregivers of persons with other chronic conditions on self-reported health, type of assistance they provide, perceptions of how caregiving interferes with their lives, and perceived level of support. A secondary analysis was conducted of the 2013 Porter Novelli SummerStyles survey data. Of the 4033 respondents, 650 adults self-identified as caregivers with 11.6% caring for people with ADRD. Over half of all caregivers reported that caregiving interfered with their lives to some extent. The greater the perceived support caregivers reported, the less they thought that caregiving interfered with their lives (p < .001). No significant differences were found between ADRD and non-ADRD caregivers regarding general health, types of assistance they provided, and perceived level of support. These findings have the potential to inform future research and practice in the development of supportive services for caregivers.

Abstract
Unique to targeting the C-terminal domain of Hsp90 (C-Hsp90) is the ability to uncouple the cytotoxic and cytoprotective outcomes of Hsp90 modulation. After the identification of novobiocin as a C-Hsp90 interacting ligand a diverse gamut of novologues emerged, from which KU-32 and KU-596 exhibited strong neuroprotective activity. However, further development of these ligands is hampered by the difficulty to obtain structural information on their complexes with Hsp90. Using saturation transfer difference (STD) NMR spectroscopy, we found that the primary binding epitopes of KU-32 and KU596 map at the ring systems of the ligands and specifically the coumarin and biphenyl structures, respectively. Based on both relative and absolute STD effects, we identified KU-596 sites that can be explored to design novel third-generation novologues. In addition, chemical shift perturbations obtained by methyl-TROSY reveal that novologues bind at the cryptic, C-Hsp90 ATP-binding pocket and produce global, long-range structural rearrangements to dimeric Hsp90.

Abstract
Inhibition of the Hsp90 C-terminus is an attractive therapeutic approach for the treatment of cancer. Novobiocin, the first Hsp90 C-terminal inhibitor identified, contains a synthetically complex noviose sugar that has limited the generation of structure-activity relationships for this region of the molecule. The work described herein utilizes various ring systems as noviose surrogates to explore the size and nature of the surrounding binding pocket.

Abstract
Based on a theoretical framework describing culturally sensitive (CS) health communication, this experiment tested the relative contributions of surface structure and deep structure in the recall of oral health information from pamphlets varied in written message and images. Using a 2 × 2 factorial design, Spanish-speaking Mexican heritage mothers of children under six (n = 160) were randomly assigned to read one of four 12-page pamphlets containing the same oral health information in Spanish: (1) standard written message/standard images; (2) standard written message/CS images; (3) CS written message/standard images; and (4) CS written message/CS images. Participants completed a 22-item oral health knowledge questionnaire before and after reading the pamphlet. Controlling for the effects of pretest scores, acculturation, and educational level on information recall, findings showed significant positive main effects for CS images (F(1, 152) = 5.03, p = .026, partial ŋ2 = .032) and CS written message (F(1, 152) = 5.21, p = .024, partial ŋ2 = .033). There was no interaction. These results support the two dimensions of CS and their independent effects. They should be applicable to a variety of health communication channels. Further research is needed to investigate the causal mechanism behind the observed effects.

Abstract
This study assessed smokers' responses to different smoking cessation topics and imagery for cigarette package inserts. Adult smokers from Canada (n = 1000) participated in three discrete choice experiments (DCEs): DCE 1 assessed five cessation benefit topics and five imagery types; DCE 2 assessed five messages with tips to improve cessation success and five imagery types; DCE 3 assessed four reproductive health benefits of cessation topics and four imagery types. In each DCE, participants evaluated four or five sets of four inserts, selecting the most and least motivating (DCEs 1 & 3) or helpful (DCE 2) for quitting. Linear mixed models regressed choices on insert and smoker characteristics. For DCE 1, the most motivating messages involved novel disease topics and imagery of younger women. For DCE 2, topics of social support, stress reduction and nicotine replacement therapy were selected as most helpful, with no differences by imagery type. For DCE 3, imagery influenced choices more than topic, with imagery of a family or a mom and baby selected as most motivating. Statistically significant interactions for all three experiments indicated that the influence of imagery type on choices depended on the message topic. Messages to promote smoking cessation through cigarette pack inserts should consider specific combinations of message topic and imagery.

Abstract
Additional research is needed to guide the design of narratives for use in practice-oriented, naturalistic settings to maximize health behavior change, particularly among populations affected by health disparities. This mixed-methods study explored the influence of cultural tailoring and emotional arousal on identification and message recall in narratives promoting childhood obesity prevention among 40 Mexican American mothers. Participants were also asked about narrative exposure, narrative preferences, and beliefs about the purpose of a story. Participants were randomly assigned to listen to two stories: (a) a story tailored on noncultural or cultural variables, and (b) a story designed to enhance or minimize emotional arousal. Participants reported high engagement and identification with all stories. Participants generally envisioned protagonists as Latina, despite limited cues, and identified with protagonists in four ways: sharing personal characteristics; having similar thoughts and feelings; engaging in similar actions; and experiencing similar situations. Mothers were most interested in narratives that helped them to improve their lives. Findings from this study yield several hypotheses for consideration in future study, including ways in which story setting and message enactment may moderate message recall.

Abstract
Objective The objective of this study was to describe participant engagement and examine predictors of weight loss and points earned through the point-based incentive system of the Social Pounds Off Digitally (POD) app. Materials and methods Overweight and obese adults with Android smartphones/tablets (body mass index 25-49.9 kg/m2; N = 24) were recruited for a 3-month weight loss intervention. Participants completed a survey assessing demographics and personality and had their weight measured. Participants received the content of the intervention via podcasts and used the Social POD app to self-monitor diet, physical activity, and weight. The Social POD app contained: tracking features; in-app notifications to track; pre-set goals for tracking; newsfeed for updates on others' goal attainment; ability to earn and track points for usage (exchanged for study-provided prizes); and a message screen. Analyses examined relationships between percent weight loss, personality characteristics, and total points earned. Results A total of 4843 points were earned (mean = 202 ± 105 points/participant). Most participants earned all three prizes (62.5%), followed by two prizes (21%), no prizes (12.5%), and one prize (4%). Total points earned significantly predicted percent weight loss (B = -0.02, p = .01), and higher conscientiousness significantly predicted greater total points earned (B = 10.27, p = .01), but other personality characteristics assessed did not. Conclusion A mobile app yielded moderately high participant engagement, as demonstrated by points earned. Earning points was significantly associated with percent weight loss, and conscientiousness was significantly associated with total points earned. Future research should examine whether point systems impact health behavior and weight loss when rewards are discontinued. Clinical trial registration number NCT02344836.

Abstract
OBJECTIVE To explore how a sample of Mexican American mothers with preschool-aged children recruited from a Midwestern Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinic obtained information about 4 behaviors associated with childhood obesity risk: eating, physical activity, screen time, and sleep. DESIGN One-on-one structured interviews in which participants were asked how they communicated with family, learned to take care of their first infant, and obtained information about the 4 targeted behaviors for their preschool-aged child. SETTING An urban WIC clinic in the Midwest. PARTICIPANTS Forty Mexican-descent mothers enrolled in WIC with children aged 3-4 years. PHENOMENON OF INTEREST Exposure to information about the 4 targeted behaviors among Mexican-descent mothers participating in WIC. ANALYSIS Quantitative and qualitative data were used to characterize and compare across participants. RESULTS Participants primarily obtained information from their child's maternal grandmother during their first child's infancy and from health professionals for their preschool-aged child. Participants typically obtained information through interpersonal communication, television, and magazines. Participants were most interested in healthy eating information and least interested in screen time information. Some participants did not seek information. CONCLUSIONS AND IMPLICATIONS Participants engaged in different patterns of information seeking across their child's development and the 4 behaviors, which suggests that future research should be behaviorally specific. Findings from this study suggest several hypotheses to test in future research.

Abstract
Inhibition of the Hsp90 C-terminus is an attractive therapeutic paradigm for the treatment of cancer, however the developmental space of C-terminal inhibitors is limited. It was hypothesized that the combination of two previously identified scaffolds into a single structure could provide a platform for which to probe the three-dimensional space within the Hsp90 C-terminal binding pocket. The resulting chimeric compounds displayed anti-proliferative activity at low micromolar concentrations and manifested inhibitory activity in an Hsp90-dependent rematuration assay. Initial structure-activity relationships suggest that this new scaffold binds Hsp90 in a conformation different from that of the parent compounds, and consequently, provides a new opportunity to develop more efficacious inhibitors of the Hsp90 C-terminal binding pocket.

Abstract
OBJECTIVE To test the efficacy of a weight loss mobile app based on recommender systems and developed by experts in health promotion and computer science to target social support and self-monitoring of diet, physical activity (PA), and weight (Social POD app), compared to a commercially available diet and PA tracking app (standard). MATERIALS AND METHODS Overweight adults [N=51] were recruited and randomly assigned to either the experimental group [n=26; theory-based podcasts (TBP)+Social POD app] or the comparison group (n=25; TBP+standard app). The Social POD app issued notifications to encourage users to self-monitor and send theory-based messages to support users who had not self-monitored in the previous 48h. Independent samples t-test were used to examine group differences in kilograms lost and change in BMI. Analysis of covariance was used to analyze secondary outcomes while controlling for baseline values. RESULTS Participant attrition was 12% (n=3 experimental and n=3 comparison). Experimental group participants lost significantly more weight (-5.3kg, CI: -7.5, -3.0) than comparison group (-2.23kg, CI: -3.6, -1.0; d=0.8, r=0.4, p=0.02) and had a greater reduction in BMI (p=0.02). While there were significant differences in positive outcome expectations between groups (p=0.04) other secondary outcomes (e.g., caloric intake and social support) were not significant. DISCUSSION Use of the Social POD app resulted in significantly greater weight loss than use of a commercially available tracking app. This mobile health intervention has the potential to be widely disseminated to reduce the risk of chronic disease associated with overweight and obesity.
