RESUMEN

Surface water samples were collected from 264 sites across 46 U.S national parks during the period of 2009-2019. The number of sites within each park ranged from 1 to 31 and the number of samples collected within each park ranged from 1 to 201. Samples were analyzed for up to 340 trace organic contaminants (TrOCs), including pharmaceuticals, personal care products, pesticides, and various contaminants indicative of anthropogenic influence (e.g., fragrances, surfactants, flame retardants). A total of 155 TrOCs was detected in at least one sample with concentrations ranging from the reporting level of 10 ng/L (multiple contaminants) to 11,900 ng/L (p-cresol). Except for bisphenol A, DEET, theobromine, and gabapentin, TrOCs were detected in <20% of samples. Despite the relatively low detection frequencies, when TrOCs were detected, concentrations were similar to those reported from other regional or national studies. We compared detected concentrations to bioactivity concentrations and water quality benchmarks, when available, to identify occurrences of elevated concentrations and to estimate the potential for biological effects to aquatic biota. Elevated concentrations of 27 TrOCs, mostly pesticides, were detected throughout the study. To gain insight regarding potential sources, we related watershed characteristics (e.g., land cover, presence of point sources) to the number of TrOCs detected at each site. We found that the presence of wastewater treatment plants and the proportion of the watershed classified as agricultural land were the most influential variables for describing the number of pharmaceuticals and the number of pesticides present, respectively. This study represents the largest-scale study characterizing the presence and magnitude of TrOCs in U.S. national park surface waters, to date. These data provide a baseline that can be used to inform future monitoring within the parks and to assess changes in water quality.

RESUMEN

OBJECTIVES: To describe long acting reversible contraception (LARC) initiation in emergency contraception (EC) visits. STUDY DESIGN: EC clients age 18-35 years at four Utah family planning clinics between February 2021 and April 2023 chose between oral EC and three LARC options. RESULTS: Of 2106 EC clients approached, 306 (14.5%) requested LARC and 293 initiated a device: 160 (55%) an etonogestrel implant+ oral levonorgestrel (LNG), 72 (25%) a copper intrauterine device (IUD), and 61 (21%) a 52 mg levonorgestrel IUD (p < 0.001). CONCLUSIONS: In this observational study, one in seven EC clients initiated a LARC method and more frequently selected the etonogestrel implant with oral levonorgestrel over an IUD. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov NCT04678817; registered 12/16/20.

RESUMEN

BACKGROUND: Energy requirement assessment is a cornerstone for nutrition practice. The extent to which total energy expenditure (TEE; indicator of energy requirements) has been measured in adults with chronic diseases has not been explored. OBJECTIVES: This systematic review aimed to characterize evidence on TEE among individuals with chronic diseases and describe TEE across chronic diseases and in comparison to controls without a chronic disease. METHODS: A literature search using terms related to doubly labeled water and TEE was conducted in PubMed, MEDLINE, Web of Science, and Embase. Eligible articles included those that measured TEE using doubly labeled water in adults with a major chronic disease. Methodological quality was determined using the Academy of Nutrition and Dietetics quality criteria checklist. Sample size-weighted TEE was calculated in each chronic disease subgroup. RESULTS: Fifty studies were included, of which 15 had a control group. Median sample size was 20 participants, and approximately half of studies were published over 10 y ago. Thirty-five (70%) studies reported resting energy expenditure, and approximately half (k = 26) reported physical activity level. Methodological quality was neutral (k = 25) or positive (k = 23) for most studies. TEE among individual studies ranged from 934 to 3274 kcal/d. Mean weighted TEE was lowest among gastrointestinal (1786 kcal/d) and neurologic (2104 kcal/d) subgroups and highest among cancer (2903 kcal/d), endocrine (2661 kcal/d), and autoimmune (2625 kcal/d) subgroups. Excluding 1 article in cancer survivors resulted in a low TEE in the cancer subgroup (2112 kcal/d). Most studies with a control group reported no differences in TEE between controls and patients; however, only 1 study was powered for between-group comparisons. CONCLUSIONS: Energy requirements vary across chronic diseases, although there is insufficient evidence to suggest that TEE in patients with chronic disease is different than that among controls. Further research is needed to inform energy requirement recommendations that consider chronic disease. This review was registered at PROSPERO as CRD42022336500 (https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=336500).

RESUMEN

BACKGROUND: Connecting end-users to research evidence has the power to improve patient knowledge and inform health decision-making. Differences in the culture and language of the end users may shape the effectiveness of knowledge mobilization (KMb). This scoping review set out to understand current approaches and methods when creating or adapting KMb products for culturally and linguistically diverse (CALD) audiences. METHODS: We searched 3 databases (Ovid Medline, CINAHL via EBSCOhost, PsychINFO) from 2011 until August 2023. We included any literature about KMb product creation or adaptation processes serving CALD communities. A primary reviewer screened all identified publications and a second reviewer screened publications excluded by the primary. Data were extracted using a standardized form by one reviewer and verified by a second reviewer. Studies were categorized by type of adaptations ('surface' and/or 'deep' structure) and mapped based on type of stakeholder engagement used in the research approach (i2S model), and end-user involvement (content, design, evaluation and dissemination) in KMb product creation or adaptation. RESULTS: Ten thousand two hundred ninety-nine unique titles and abstracts were reviewed, 670 full-text studies were retrieved and reviewed, and 78 studies were included in final data extraction and mapping. Twenty-four studies (31%) created or adapted exclusively text-based KMb products such as leaflets and pamphlets and 49 (63%) produced digital products such as videos (n = 16, 33%), mobile applications (n = 14, 29%), and eHealth websites (n = 7, 14%). Twenty-five studies (32%) reported following a framework or theory for their creation or adaptation efforts. Twenty-eight studies (36%) engaged stakeholders in the research approach. Nearly all (96%) involved end-users in creating or adapting the KMb products through involvement in content development (n = 64), design features (n = 52), evaluation (n = 44) and dissemination (n = 20). Thirty-two (41%) studies included reflections from the research teams on the processes for creating or adapting KMb products for CALD communities. CONCLUSION: Included studies cited a variety of methods to create or adapt KMb products for CALD communities. Successful uptake of created or adapted KMb products was often the result of collaboration and involvement with end-users for more applicable, accessible and meaningful products. Further research developing guidance and best practices is needed to support the creation or adaptation of KMb products with CALD communities.

RESUMEN

To identify priority areas to improve the design, conduct, and reporting of pediatric clinical trials, the international expert network, Standards for Research (StaR) in Child Health, was assembled and published the first 6 Standards in Pediatrics in 2012. After a recent review summarizing the 247 publications by StaR Child Health authors that highlight research practices that add value and reduce research "waste," the current review assesses the progress in key child health trial methods areas: consent and recruitment, containing risk of bias, roles of data monitoring committees, appropriate sample size calculations, outcome selection and measurement, and age groups for pediatric trials. Although meaningful change has occurred within the child health research ecosystem, measurable progress is still disappointingly slow. In this context, we identify and review emerging trends that will advance the agenda of increased clinical usefulness of pediatric trials, including patient and public engagement, Bayesian statistical approaches, adaptive designs, and platform trials. We explore how implementation science approaches could be applied to effect measurable improvements in the design, conducted, and reporting of child health research.

RESUMEN

BACKGROUND: The impact of midwifery, and especially Indigenous midwifery, care for Indigenous women and communities has not been comprehensively reviewed. To address this knowledge gap, we conducted a mixed-methods systematic review to understand Indigenous maternal and infant outcomes and women's' experiences with midwifery care. METHODS: We searched nine databases to identify primary studies reporting on midwifery and Indigenous maternal and infant birth outcomes and experiences, published in English since 2000. We synthesized quantitative and qualitative outcome data using a convergent segregated mixed-methods approach and used a mixed-methods appraisal tool (MMAT) to assess the methodological quality of included studies. The Aboriginal and Torres Strait Islander Quality Appraisal Tool (ATSI QAT) was used to appraise the inclusion of Indigenous perspectives in the evidence. RESULTS: Out of 3044 records, we included 35 individual studies with 55% (19 studies) reporting on maternal and infant health outcomes. Comparative studies (n = 13) showed no significant differences in mortality rates but identified reduced preterm births, earlier prenatal care, and an increased number of prenatal visits for Indigenous women receiving midwifery care. Quality of care studies indicated a preference for midwifery care among Indigenous women. Sixteen qualitative studies highlighted three key findings - culturally safe care, holistic care, and improved access to care. The majority of studies were of high methodological quality (91% met ≥80% criteria), while only 14% of studies were considered to have appropriately included Indigenous perspectives. CONCLUSION: This review demonstrates the value of midwifery care for Indigenous women, providing evidence to support policy recommendations promoting midwifery care as a physically and culturally safe model for Indigenous women and families.

RESUMEN

The objective of this review was to explore parents' experiences and information needs regarding management of their child with an intellectual and/or developmental disability (IDD) in the emergency department (ED). We searched six electronic databases and grey literature to identify primary studies in English published since 2000. We synthesized quantitative and qualitative outcome data simultaneously using a convergent integrated approach and used a Mixed Methods Appraisal Tool (MMAT) to assess methodological quality of the included studies. Nine articles derived from seven studies were included (3 qualitative, 3 quantitative, 1 mixed method). Four main themes related to parents' self-reported experiences were identified: 1) appropriateness of the ED to manage and support their child; 2) acknowledgement/recognition of their child's IDD and incorporation of those considerations into overall care and management; 3) managing and navigating the ED environment; and 4) decision to disclose their child's condition when visiting the ED. Two articles provided data relevant to information needs, highlighting parents' desire to have resources supporting ED orientation and access to services within and outside of the ED setting. From the limited number of studies, it was evident that parents wanted better communication with healthcare providers and a greater understanding by ED staff around physical space settings needed to support their child. Resources supporting ED staff and parents to communicate effectively and work together can ensure that children with IDDs care needs are met. Further research into understanding parents' experiences and information needs related to managing a child with an IDD in the ED is needed to guide the development of effective resources.

RESUMEN

Incorporation of a polar filler such as silica into a nonpolar rubber matrix is challenging and energy consuming due to their large difference in polarity. Epoxidation of carbon-carbon double bonds in unsaturated rubber, especially for rubber with low unsaturation such as butyl rubber, is an effective method to introduce polar functional groups to the rubber macromolecules for better filler dispersion. Although different epoxidation reagents including hydrogen peroxide (H2O2), peracid, and meta-chloroperoxybenzoic acid (mCPBA) have been previously reported, these reagents have different drawbacks. In this article, a metal-free epoxidation reagent, dimethyl dioxirane (DMDO), generated from acetone and Oxone is explored for efficient epoxidation of rubber with low unsaturation. The effects of the addition manner of the reactant Oxone and buffer sodium bicarbonate (NaHCO3) and reaction temperature on the epoxide formation are studied. Compared to peracid, a faster and more efficient epoxidation without the generation of a ring-opened product is achieved when DMDO is used as the epoxidation reagent. Furthermore, it is found that the epoxidation using DMDO is not sensitive to the water concentration in the rubber solution up to 20 wt %. The addition of quaternary ammonium salt as a phase transfer catalyst not only improves the conversion but also further increases the water tolerance to 25 wt %. The reaction conditions for preparation of epoxidized butyl rubber with different percentages of epoxide group are optimized by Design of Experiments (DoE). At the end, improved dispersion of silica in the matrix of epoxidized butyl rubber is achieved, as revealed by the rubber process analyzer (RPA) and atomic force microscopy (AFM).

RESUMEN

Recent work in combustion and atmospheric chemistry has revealed cases in which diastereomers must be distinguished to accurately model a reacting flow. This paper presents an open-source framework for introducing such stereoisomer resolution into a kinetic mechanism. We detail our definitions and algorithms for labeling and enumerating the stereoisomers of a molecule and then generalize our system to describe the transition state (TS) of a reaction. This allows for the stereospecific enumeration of reactants and products while accounting for "fleeting" stereochemistry that is unique to the TS. We also present the AutoMech Chemical Identifier (AMChI), an InChI-like string identifier that accounts for stereocenters omitted by InChI. This identifier is extended to describe the TSs of reactions, providing a universal lookup key for specific reaction channels. The final piece of our methodology is an analytic formula to remove redundancy from a stereoresolved mechanism when its enantiomers exist as a racemic mixture, making it as compact as possible while fully accounting for the differences between diastereomers. In applying our methodology to two subsets of the NUIGMech1.1 mechanism, we find that our approach reduces the extra species added for large-fuel oxidation from 2231 (133%, full expansion) to 694 (41%, nonredundant expansion). We also find that for pyrolysis more than a quarter of the species in the expanded mechanism cannot be properly described by an InChI string, requiring an AMChI string to communicate their identity. Finally, we find that roughly one-quarter of the large-fuel oxidation reactions and one-third of the pyrolysis reactions include fleeting TS stereochemistry, which may have relevant effects on their kinetics.

RESUMEN

INTRODUCTION: Pain affects all children, and in hospitals across North America, this pain is often undertreated. Children who visit the emergency department (ED) experience similar undertreatment, and they will often experience a painful procedure as part of their diagnostic journey. Further, children and their caregivers who experience social injustices through marginalization are more likely to experience healthcare disparities in their pain management. Still, most of our knowledge about children's pain management comes from research focused on well-educated, white children and caregivers from a middle- or upper-class background. The aim of this scoping review is to identify, map, and describe existing research on (a) how aspects of marginalization are documented in randomized controlled trials related to children's pain and (b) to understand the pain treatment and experiences of marginalized children and their caregivers in the ED setting. METHODS AND ANALYSIS: The review will follow Joanna Briggs Institute methodology for scoping reviews using the Participant, Concept, Context (PCC) framework and key terms related to children, youth, pain, ED, and aspects of marginalization. We will search Medline, Embase, PsychInfo, CINAHL, Web of Science, Cochrane Library Trials, iPortal, and Native Health Database for articles published in the last 10 years to identify records that meet our inclusion criteria. We will screen articles in a two-step process using two reviewers during the abstract and full-text screening stages. Data will be extracted using Covidence for data management and we will use a narrative approach to synthesize the data. ETHICS AND DISSEMINATION: Ethical approval is not required for this review. Findings will be disseminated in academic manuscripts, at academic conferences, and with partners and knowledge users including funders of pain research and healthcare professionals. Results of this scoping review will inform subsequent quantitative and qualitative studies regarding pain experiences and treatment of marginalized children in the ED.

RESUMEN

Freshwater mussels provide invaluable ecological services but are threatened by habitat alteration, poor water quality, invasive species, climate change, and contaminants, including contaminants of emerging concern (CECs). Contaminants of emerging concerns are well documented in aquatic environments, including the Great Lakes Basin, but limited information is available on how environmentally relevant mixtures affect freshwater mussel biology throughout their varied life stages. Our main goal was to assess mussels' reproductive output in response to exposure to agricultural and urban CEC mixtures during glochidial development through juvenile transformation and excystment focusing on how exposure duration and treatment affect: (1) the number of glochidia prematurely released by brooding females, (2) glochidial transformation through host-fish excystment, and (3) the number of fully metamorphosed juveniles able to continue the lifecycle. Mussels and host fish were exposed to either a control water (CW), control ethanol (CE), agriculture CEC mixture (AM), or urban CEC mixture (UM) for 40 and 100 days. We found no effect from treatment or exposure duration on the number of glochidia prematurely released. Fewer partially and fully metamorphosed AM juveniles were observed during the 100-day exposure, compared with the 40-day. During the 40-day exposure, CW produced more fully metamorphosed individuals compared with CE and UM, but during the 100-day exposure AM produced more fully metamorphosed individuals compared with the CW. There was reduction in fully metamorphosed juveniles compared with partially metamorphosed for CE and UM during the 40-day exposure, as well as in the CW during the 100-day exposure. These results will be important for understanding how mussel populations are affected by CEC exposure. The experiments also yielded many insights for laboratory toxicology exposure studies.

RESUMEN

BACKGROUND: The eCOVID19 Recommendations Map & Gateway to Contextualization (RecMap) website was developed to identify all COVID-19 guidelines, assess the credibility and trustworthiness of the guidelines, and make recommendations understandable to various stakeholder groups. To date, little has been done to understand and explore parents' experiences when accessing and using the RecMap website for COVID-19 health decision-making. OBJECTIVE: To explore (1) where parents look for COVID-19 health information and why, (2) parents' user experience when accessing and using the RecMap website to make health decisions, and (3) what knowledge mobilization activities are needed to increase parents' awareness, use, and engagement with the RecMap website. METHODS: We conducted a qualitative descriptive study using semistructured interviews and a think-aloud activity with parents of children aged 18 years or younger living in Canada. Participants were asked to provide feedback on the RecMap website and to "think aloud" as they navigated the website to find relevant COVID-19 health recommendations. Demographic information was collected using a web-based questionnaire. A hybrid deductive and inductive thematic approach guided analysis and data synthesis. RESULTS: A total of 21 participants (13/21, 62% mothers) were interviewed and participated in a think-aloud activity. The data were categorized into four sections, representative of key elements that deductively and inductively emerged from the data: (1) parent information seeking behaviors and preferences for COVID-19, (2) RecMap website usability, (3) perceived usefulness of the RecMap website, and (4) knowledge mobilization strategies to increase awareness, use, and engagement of the RecMap website. Parents primarily used the internet to find COVID-19 information and focused on sources that they determined to be credible, trustworthy, simple, and engaging. As the pandemic evolved, participants' information-seeking behaviors changed, specifically their topics of interest and search frequency. Most parents were not aware of the RecMap website before this study but found satisfaction with its concept and layout and expressed intentions to use and share it with others. Parents experienced some barriers to using the RecMap website and suggested key areas for improvement to facilitate its usability and perceived usefulness. Recommendations included a more user-friendly home page for lay audiences (separate public-facing user interface), improving the search and filter options, quicker navigation, clearer titles, more family-friendly graphics, and improving mobile-friendly access. Several strategies to disseminate the RecMap website were also expressed, including a mix of traditional and nontraditional methods (handouts and social media) in credible and high-traffic locations that parents frequent often. CONCLUSIONS: Overall, parents liked the concept of the RecMap website but had some suggestions to improve its usability (language, navigation, and website interface). These findings can be used to improve the RecMap website for parents and offer insight for the development and dissemination of effective web-based health information tools and resources for the general public.

RESUMEN

Effects of the Coronavirus disease 2019 (COVID-19) pandemic on children stem beyond immediate infectious and post-infectious risks. Our aim was to conduct a scoping review and produce an online Interactive Evidence Map (IEM) highlighting available literature around unintended effects of the pandemic on children's and adolescents' mental, psychosocial, and physical health. A search was run monthly in MEDLINE, PsycINFO, CENTRAL, and Cochrane COVID-19 Study Register from May 1st 2021 through April 30th 2022. All articles involving children and adolescents under 18 years of age relating to any unintended mental, psychosocial, and physical health consequences of the pandemic and resultant restrictions were included. Data were extracted and topics categorized, with corresponding data uploaded into EPPI-Reviewer and transferred to EPPI-Mapper for visualization. A total of 14,555 citations were screened and 826 (6%) articles included. Most articles reported on mental health outcomes, particularly anxiety (n = 309, 37%) and depression (n = 294, 36%). Psychosocial outcomes related to lockdowns such as loneliness (n = 120, 15%) and impact on adolescent relationships with others (n = 149, 18%) were also reported. Fewer articles examined physical consequences, but those that did mostly focused on child abuse (n = 73, 9%). Overall, currently mapped literature focuses on consequences related to mental health outcomes such as anxiety and depression.

RESUMEN

INTRODUCTION: Throughout the coronavirus disease 2019 (COVID-19) pandemic, parents and children faced significant challenges as a result of prevention measures implemented to control the spread of the disease. Ensuring that families have access to essential health information is critical for improving health outcomes and adherence to public health recommendations. Understanding parents' experiences and information needs related to the pandemic and associated health measures (e.g., vaccination, mask wearing, social distancing, etc.) will inform the development and dissemination of resources tailored to parents' needs to support informed decision making. METHODS: We conducted a qualitative descriptive study. Between September and November 2021, parents across Canada were recruited online via social media and community organisation newsletters and listservs to participate in focus groups via Zoom. Focus groups were audio-recorded and transcribed verbatim. Data were coded and analysed using thematic analysis. Participants completed a demographic questionnaire before the focus groups (via SimpleSurveys). RESULTS: Sixty-seven parents participated in 12 focus groups between October and November 2021. In relation to experiences, parents felt they were (1) constantly trying to balance everything, and (2) trying to do their best with the information they had at the time when making decisions. Regarding information needs, parents reflected on (1) how difficult it was navigating copious amounts of changing information and finding credible sources to rely on, (2) the need for resources that were easily accessible, credible and in plain language and (3) the need for resources that were tailored to their needs to support them and their children make informed decisions. CONCLUSIONS: Trying to mitigate the risk of COVID-19 infection and adhere to public health recommendations, while balancing various factors (work, online learning, and social interactions) and navigating changing information, was overwhelming for many parents. Reflecting on their needs, parents suggested tailored resources that provided concise, credible information in plain language to help them make informed decisions and navigate conflicting information. These findings reveal important knowledge gaps and highlight areas that need to be addressed to support parents during the pandemic period and beyond. PATIENT OR PUBLIC CONTRIBUTION: Members of our established Paediatric Parent Advisory Group (P-PAG) were involved as collaborators throughout the planning (grant proposal), development and execution of the study. P-PAG members gave input on the design of the questionnaire, interview guide, recruitment strategy and interpretation of findings.

RESUMEN

Predicting the synthesizability of a new molecule remains an unsolved challenge that chemists have long tackled with heuristic approaches. Here, we report a new method for predicting synthesizability using a simple yet accurate thermochemical descriptor. We introduce Emin, the energy difference between a molecule and its lowest energy constitutional isomer, as a synthesizability predictor that is accurate, physically meaningful, and first-principles based. We apply Emin to 134,000 molecules in the QM9 data set and find that Emin is accurate when used alone and reduces incorrect predictions of "synthesizable" by up to 52% when used to augment commonly used prediction methods. Our work illustrates how first-principles thermochemistry and heuristic approximations for molecular stability are complementary, opening a new direction for synthesizability prediction methods.

RESUMEN

OBJECTIVES: In an established cohort of HER Salt Lake Contraceptive Initiative participants with a prior intrauterine device (IUD) placement, we sought to (1) define the proportion of participants who reported a negative Patient Acceptable Symptom State (PASS) response, (2) explore factors associated with an unacceptable PASS response, and (3) identify pain management preferences for IUD placement. STUDY DESIGN: A retrospective survey was sent to 1440 HER Salt Lake IUD users. A PASS question queried IUD placement pain experience acceptability. We explored associations between an unacceptable PASS response and sociodemographic, reproductive and other individual characteristics using t-tests, chi-square tests, and multivariable logistic regression. RESULTS: Of those surveyed, 620 responded (43%), and 41.6% reported an unacceptable PASS response. Those with an unacceptable PASS response reported a significantly higher experienced pain level (79.2 mm vs 51.8 mm; p < 0.01) than those with an acceptable response, were more likely to have an anxiety diagnosis (47.7% vs 37.1%; p < 0.01), and have a trauma history (33.7% vs 25.1%; p = 0.02). Most patients were not offered pain control options, but 29.4% used ibuprofen and 25.3% had a support person. Regardless of PASS response, if offered, 59.0% desired numbing medication, 56.8% ibuprofen, 51% heating pad, 33.2% support person, and 31.8% anti-anxiety medication, among others. In our multivariable logistic regression model, higher pain was associated with unacceptable PASS response (OR 1.07, 95% CI 1.05-1.08; p < 0.01). CONCLUSIONS: The common finding of unacceptable pain experiences with IUD placement may cause negative perceptions of an otherwise desirable method. Incorporation of the PASS response into IUD pain management studies could expand our pain experience understanding. IMPLICATIONS: IUD placement resulted in unacceptable pain experiences for 41.6% of respondents. Screening for anxiety and trauma history could identify at-risk patients to individualize pain management strategies. Incorporation of the PASS into future IUD pain management studies could result in a more comprehensive, patient-centered measure of patient experiences.

RESUMEN

The objective of this study was to understand how youth search for mental health information online. Youth partners were engaged at the onset of the project and provided input throughout on the design, conduct and analysis. Individual, semi-structured interviews with Canadian youth with experience searching for mental health information online were conducted. Data collection and reflexive thematic analysis proceeded concurrently. Fourteen youth were interviewed. Four main themes related to how youth search online emerged: mind-set shapes the search process; external factors shape the search process; key attributes of helpful information; and cues affecting trustworthiness of online information. Findings can inform the development of youth-friendly online mental health information that is perceived as helpful and trustworthy by youth. Ensuring youth have access to quality online mental health information, accessible to how they search for it, is critical to the mental health and development of youth.

BACKGROUND: In 2016, we developed a pediatric parent advisory group to inform our research program which creates innovative knowledge translation (KT) tools for parents on priority topics related to acute childhood illness. We implemented a mixed methods strategy to evaluate the experiences of group members. The purpose of this paper is to present the findings from parent evaluations over four years and to discuss our experiences collaborating with the group over a multi-year period. METHODS: We conducted year-end surveys and interviews of group members to understand parents' perceptions of their experiences, group management, researcher interaction, and other outcomes of advisory group participation from 2018 to 2021. We applied a mixed methods approach, collecting and analyzing both quantitative (survey) and qualitative (survey/interview) data. Survey data were analyzed by term using descriptive statistics (i.e., frequencies, percentages). Open-ended survey responses were analyzed by conventional content analysis. Interview data were analysed thematically. RESULTS: Year-end survey response rates and interview participation varied over the years. Responses to evaluation questions were generally positive and most improved over time. Results prompted changes to improve P-PAG operations, such as changes to location of meetings, communications about the group's purpose, offering sufficient context for discussion items, and providing feedback about how members' input was used. Themes identified from the qualitative data related to the importance of certain aspects of group functioning, positive views of the group's current management, and potential areas for improvement. Parents regularly expressed a desire for more diversity in the group's membership and an interest in hearing more about how the research program's activities fit into the broader healthcare system and their impacts on health outcomes. CONCLUSIONS: Our experience in establishing, managing, and evaluating a parent advisory group over many years has resulted in valuable insights regarding patient engagement in health research and sustaining an advisory group over time. We have learned that an intentional and iterative approach with regular evaluations and responsive changes has been essential for fostering meaningful engagement. Significant resources are required to maintain the group; in turn, the group has made substantial and diverse contributions to the research program and its outputs.


We developed a parent advisory group in 2016 to support our research program in knowledge translation (KT, i.e., sharing research in accessible ways to inform decision-making) for child health. The purpose of the group is to involve parents in co-developing, evaluating, and sharing KT tools (e.g., videos, infographics). The group has also worked with researchers to inform methods and provide input on research projects and products. The group has been running for seven years and has involved different types of evaluations, including parent surveys and interviews. Parents had generally positive views of their experience with the group (including the group's management, interactions with researchers, etc.) and their responses mostly improved over the years. Based on parents' feedback, we made changes to improve the group's operations, such as changing the frequency and location of meetings, regular communications about the group's purpose, offering more context and time for individual discussion items, and providing feedback to parents about how their input was used. Parents regularly expressed a desire for more diversity in the group's membership. They also expressed an interest in hearing more about how the research program fit into the broader healthcare system and impacts on health outcomes. We have learned that it takes a large amount of time, effort, and funding to run the group; however, the parent contributions have been valuable and wide-reaching. We feel that the evaluations and responsive changes to the group over time have been essential to sustain and foster meaningful engagement and achieve the group's objectives.

RESUMEN

AIMS: This study explored the association between social determinants of health (SDOH) and diabetes care behaviors among individuals with health insurance. METHODS: Data from 57,206 US residents, representing a population of over 25.58 million adults with health insurance and diagnosed diabetes, were included in this cross-sectional analysis of data from the 2017 Behavioral Risk Factor Surveillance System. Logistic regression models were constructed to evaluate the likelihood of various diabetes care behaviors given the presence of several SDOH (e.g., food insecurity, poverty, housing insecurity, rurality). RESULTS: Most respondents exercised, ate vegetables, saw a provider for diabetes-related care in the last year, and reported checking their feet and testing their blood sugar daily. Not feeling safe (odds ratio (OR) 1.77, 95 % confidence interval (CI) 1.04, 3.01) was related to never checking blood sugar. Experiencing frequent stress was associated with a lower likelihood of exercise (OR .77, 95% CI 0.60, 0.999) and lower likelihood of checking blood sugar at least once a day (OR 0.73, 95% CI 0.54, 0.99). Food insecurity was associated with lower likelihood of vegetable consumption (OR 0.63, 95 % CI 0.47, 0.85) but a higher likelihood of checking blood sugar (OR 1.80, 95 % CI 1.26, 2.57). Low-income respondents were less likely to exercise (OR 0.72, 95 % CI 0.64, 0.80) or eat vegetables (OR 0.83, 95 % CI 0.75, 0.93) but more likely to check their feet (OR 1.19, 95 % CI 1.04, 1.35) and blood sugar at least once per day (OR 1.15, 95% CI 1.01, 1.31). Those who rent their home were also more likely to check their blood sugar (OR 1.22, 95% CI 1.07, 1.37) but less likely to have eaten vegetables in the last week (OR 0.87, 95% CI 0.78, 0.97). Respondents living in rural areas were more likely to have visited a provider in the last year (OR 1.21 95% CI 1.00, 1.47). CONCLUSIONS: SDOH can adversely affect diabetes self-care behaviors, providers should assist vulnerable patients by connecting them with community resources and providing individualized care.
