RESUMO

PURPOSE: To evaluate individual and community sociodemographic factors that predict bowel regimen adherence in youth and young adults with Spina Bifida (SB) following participation in a bowel management program (BMP). METHODS: Participants were drawn from clinical cases seen through an International Center for Colorectal and Urogenital Care. Area deprivation index (ADI) scores were extracted from participant addresses and bowel regimen adherence data were collected from the electronic medical record (EMR). RESULTS: Participants' mean age was 8.06 years old, 51.7% were male, 72.4% white, 37.9% Hispanic, 56.9% government insurance, 89.7% myelomeningocele, 15.5% non-adherent. Average neighborhood disadvantage was 5.19 (SD:2.83, range:1-10). After controlling for variables correlated with adherence (p < .20), every one decile higher neighborhood disadvantage score was associated with a 48% decrease in the odds of being adherent (OR = 0.52, p = .005, 95% CI: - 101.90, - 0.21). CONCLUSION: Our results suggest that neighborhood disadvantage is a strong predictor of medical adherence following a BMP, more so than other sociodemographic and health-related variables. These results may assist with identifying which individuals may be at higher risk for poor health outcomes due to neighborhood socioeconomic disadvantage and help health care systems intervene proactively.

RESUMO

The gut microbiome possesses numerous biochemical enzymes that biosynthesize metabolites that impact human health. Bile acids comprise a diverse collection of metabolites that have important roles in metabolism and immunity. The gut microbiota-associated enzyme that is responsible for the gateway reaction in bile acid metabolism is bile salt hydrolase (BSH), which controls the host's overall bile acid pool. Despite the critical role of these enzymes, the ability to profile their activities and substrate preferences remains challenging due to the complexity of the gut microbiota, whose metaproteome includes an immense diversity of protein classes. Using a systems biochemistry approach employing activity-based probes, we have identified gut microbiota-associated BSHs that exhibit distinct substrate preferences, revealing that different microbes contribute to the diversity of the host bile acid pool. We envision that this chemoproteomic approach will reveal how secondary bile acid metabolism controlled by BSHs contributes to the etiology of various inflammatory diseases.

RESUMO

BACKGROUND: Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability. Early Check, a voluntary newborn screening study, screened 18,833 newborns for FXS over ∼3 years. Exploring parental attitudes and perspectives can provide insight to the potential future acceptability of public health screening. METHODS AND PROCEDURES: Mothers of infants who received a screen positive result for FXS (n = 6) or fragile X premutation (FXPM; n = 18) were interviewed about their perceptions and experiences. OUTCOMES AND RESULTS: Mothers of children with FXS described utility in receiving information about their child, particularly to monitor for potential developmental issues and intervene early; overall mothers did not regret participating. Mothers reported various reactions to receiving the FXS or FXPM results including (1) stress and worry; (2) guilt; (3) sadness and disappointment; (4) neutrality, relief, and acceptance; and (5) confusion and uncertainty. CONCLUSIONS AND IMPLICATIONS: Despite initial reactions such as sadness, stress, and worry, mothers found value in learning of their child's presymptomatic diagnosis of FXS, particularly the anticipated long-term benefits of early diagnosis to their child's health and wellbeing. Our results indicate that professionals returning positive newborn screening results should anticipate and prepare for reactions such as parental shock, guilt, sadness, and uncertainty. Genetic counseling and psychosocial support are critical to supporting families.

RESUMO

The gut microbiome has major roles in modulating host physiology. One such function is colonization resistance, or the ability of the microbial collective to protect the host against enteric pathogens1-3, including enterohaemorrhagic Escherichia coli (EHEC) serotype O157:H7, an attaching and effacing (AE) food-borne pathogen that causes severe gastroenteritis, enterocolitis, bloody diarrhea and acute renal failure4,5 (haemolytic uremic syndrome). Although gut microorganisms can provide colonization resistance by outcompeting some pathogens or modulating host defence provided by the gut barrier and intestinal immune cells6,7, this phenomenon remains poorly understood. Here, we show that activation of the neurotransmitter receptor dopamine receptor D2 (DRD2) in the intestinal epithelium by gut microbial metabolites produced upon dietary supplementation with the essential amino acid L-tryptophan protects the host against Citrobacter rodentium, a mouse AE pathogen that is widely used as a model for EHEC infection8,9. We further find that DRD2 activation by these tryptophan-derived metabolites decreases expression of a host actin regulatory protein involved in C. rodentium and EHEC attachment to the gut epithelium via formation of actin pedestals. Our results reveal a noncanonical colonization resistance pathway against AE pathogens that features an unconventional role for DRD2 outside the nervous system in controlling actin cytoskeletal organization in the gut epithelium. Our findings may inspire prophylactic and therapeutic approaches targeting DRD2 with dietary or pharmacological interventions to improve gut health and treat gastrointestinal infections, which afflict millions globally.

RESUMO

OBJECTIVES: Gun violence in the United States is a public health crisis. In 2019, gun injury became the leading cause of death among children aged birth to 19 years. Moreover, the United States has had 57 times as many school shootings as all other major industrialized nations combined. The purpose of this study was to understand the frequency of school-related gun violence across a quarter century, considering both school shootings and school mass shootings. METHODS: We drew on 2 publicly available datasets whose data allowed us to tabulate the frequency of school shootings and school mass shootings. The databases contain complementary data that provide a longitudinal, comprehensive view of school-related gun violence over the past quarter century. RESULTS: Across the 1997-1998 to 2021-2022 school years, there were 1453 school shootings. The most recent 5 school years reflected a substantially higher number of school shootings than the prior 20 years. In contrast, US school mass shootings have not increased, although school mass shootings have become more deadly. CONCLUSIONS: School shootings have risen in frequency in the recent 25 years and are now at their highest recorded levels. School mass shootings, although not necessarily increasing in frequency, have become more deadly. This leads to detrimental outcomes for all the nation's youth, not just those who experience school-related gun violence firsthand. School-based interventions can be used to address this public health crisis, and effective approaches such as Multi-Tiered Systems of Supports and services should be used in support of students' mental health and academic and behavioral needs.

RESUMO

Self-injurious thoughts and behaviors (SITBs), including suicidal thoughts, suicide attempts, and nonsuicidal self-injury, are highly prevalent among adolescents. Identifying adolescents at risk for SITBs relies on their disclosure, and these disclosures commonly occur in therapy context. Moreover, therapists often breach confidentiality to inform adolescents' parent or guardian when they disclose SITBs. Research has explored rates of and barriers to disclosure among adolescents, yet no studies have examined adolescents' experiences of disclosure in the therapy context. Further, no studies have examined adolescents' experiences when their parents are then informed. In this study, we examined qualitative responses from 1495 adolescents who had experienced a SITB disclosure in the therapy context. Qualitative questions included asking adolescents to describe how the SITB disclosure occurred, how their parents were informed, and their parents' reactions. Using open and axial coding, several themes emerged. Adolescents described therapist breaches of confidentiality as collaborative, noncollaborative, or unclear. Adolescents described their parents' affective responses, communication about SITBs, validating and invalidating responses, treatment-oriented responses, and ways that parents restricted their access to people, places, and activities. Findings have implications for the development of clinical guidelines when adolescents disclose SITBs in therapy and highlight areas for future research in adolescent SITB disclosure.

RESUMO

BACKGROUND: Funded by the Centers for Disease Control and Prevention Racial and Ethnic Approaches to Community Health Initiative, Live Well Allegheny: Lifting Wellness for African Americans (LWA) in Allegheny County, Pennsylvania, aims to enhance health equity by addressing chronic disease in six African American communities via three key strategies: nutrition, physical activity, and community-clinical linkages. OBJECTIVES: This manuscript describes the coalition's partnership dynamics and evaluation methods with a focus on nutrition strategies. METHODS: We have a network of committed partners implementing the strategies and we are evaluating our efforts using community asset mapping, county population-based survey data, qualitative process interviews, focus groups, and program performance measures. RESULTS: The LWA coalition is the culmination of years of partnership building, which allows for more targeted activities related to health equity in the region. Thus far, the LWA coalition is thriving. The network of committed and talented partners in the nutrition strategy (healthy nutrition standards, food systems, and breastfeeding) reached 22 sites and more than 46,000 people during the first 2 years of the project. Process interviews conducted as part of the evaluation identified challenges and successes of implementation, and development of the coalition. CONCLUSIONS: This comprehensive evaluation approach supports formative processes, evaluation metrics, and prolonged sustainability plans of this community-based coalition.

RESUMO

OBJECTIVE: The aim of this study was to compare the performance of direct amplification of viral nucleic acid from transport medium to extracted nucleic acid for polymerase chain reaction (PCR), sequencing, and genotyping applications. METHODS: XpressAmp lysate and extracted total nucleic acid from viral transport medium containing nasopharyngeal specimens were evaluated across different molecular applications to determine performance characteristics. RESULTS: SARS-CoV-2 quantitative PCR and angiotensin-converting enzyme (ACE) genotyping assays worked well with XpressAmp lysate, almost equal with or better than extracted nucleic acid in some specimens. However, XpressAmp completely failed to perform in next-generation sequencing for strain typing. Both protocols failed to detect ACE2 expression in viral transport medium. CONCLUSION: Direct amplification of viral nucleic acid from viral transport medium containing nasopharyngeal specimen works well for molecular assays with low thresholds of quality; however, it does have limitations with assays that require high quality nucleic acid for input. Use of the XpressAmp protocol significantly improves turnaround time and allows for easy ramp-up of PCR and genotyping assays.

RESUMO

Globally, youth have experienced heightened levels of stress due to the COVID-19 pandemic, though many youth showed resilience to mental health problems despite this increased stress. The current review covers emerging literature published in the past three years on resilience factors that promote more positive mental health in youth ages 10-18 years. These factors generally fall into three categories: 1) resilience factors at the level of the individual, 2) social resilience factors, and 3) interventions to enhance youth resilience during the pandemic. We include recommendations for future longitudinal research to better understand and promote resilience given the context of the pandemic, particularly for youth who experienced high levels of adversity.

RESUMO

BACKGROUND: Adolescents and young adults (AYAs) with cancer are at high risk of poor psychosocial outcomes, and evidence-based interventions designed to meet their psychosocial and communication needs are lacking. The main objective of this project is to test the efficacy of a new adaptation of the Promoting Resilience in Stress Management intervention for AYAs with Advanced Cancer (PRISM-AC). METHODS/DESIGN: The PRISM-AC trial is a 2-arm, parallel, non-blinded, multisite, randomized controlled trial. 144 participants with advanced cancer will be enrolled and randomized to either usual, non-directive, supportive care without PRISM-AC ("control" arm) or with PRISM-AC ("experimental" arm). PRISM is a manualized, skills-based training program comprised of four 30-60 min, one-on-one sessions targeting AYA-endorsed resilience resources (stress-management, goal-setting, cognitive-reframing, and meaning-making). It also includes a facilitated family meeting and a fully equipped smartphone app. The current adaptation includes an embedded advance care planning module. English- or Spanish-speaking individuals 12-24 years old with advanced cancer (defined as progressive, recurrent, or refractory disease, or any diagnosis associated with < 50% survival) receiving care at 4 academic medical centers are eligible. Patients' caregivers are also eligible to participate in this study if they are able to speak and read English or Spanish, and are cognitively and physically able to participate. Participants in all groups complete surveys querying patient-reported outcomes at the time of enrollment and 3-, 6-, 9-, and 12-months post-enrollment. The primary outcome of interest is patient-reported health-related quality of life (HRQOL) and secondary outcomes of interest include patient anxiety, depression, resilience, hope and symptom burden, parent/caregiver anxiety, depression and health-related quality of life, and family palliative care activation. We will conduct intention-to-treat analysis to compare the group means of primary and secondary outcomes between PRISM-AC arm and control arm with regression models. DISCUSSION: This study will provide methodologically rigorous data and evidence regarding a novel intervention to promote resilience and reduce distress among AYAs with advanced cancer. This research has the potential to offer a practical, skills-based curriculum designed to improve outcomes for this high-risk group.

RESUMO

This paper provides the detailed protocol for a pilot study testing the feasibility, acceptability, and initial efficacy of a targeted two-phase, remotely delivered early intervention program for infants with neurogenetic conditions (NGC) and their caregivers. The Parent and Infant Inter(X)action Intervention (PIXI) is designed to support parents and infants with a NGC diagnosed in the first year of life. PIXI is implemented in two phases, with the first phase focusing on psychoeducation, parent support, and how to establish routines for supporting infant development. Phase II helps parents learn targeted skills to support their infant's development as symptoms may begin to emerge. The proposed non-randomized feasibility pilot study will establish the feasibility of a year-long virtually implemented intervention program to support new parents of an infant diagnosed with an NGC.

RESUMO

The objective of this systematic review was to determine the current state of the literature regarding how adipocytokines associate with mental health symptoms/disorders in youth. Findings summarized in this review suggested that in neurodevelopmental disorders, higher levels of leptin, ghrelin, resistin, and visfatin as well as lower levels of adiponectin, retinol-binding protein 4, and progranulin predicted increased risk for or were conflated with autism spectrum disorder. Adipocytokine correlates of attention-deficit hyperactivity disorder and related symptoms included higher apelin, higher leptin-to-adiponectin ratio, and lower adiponectin. Evidence from studies examining anxiety symptoms evinced mixed results regarding leptin, and one study suggested higher levels of ghrelin. Depressive symptoms correlated with higher leptin and ghrelin. Research examining posttraumatic stress symptoms found higher levels of ghrelin. In research examining broadband symptoms, conflicting results emerged for associations between internalizing symptoms (i.e., symptoms of emotional stress) and leptin in youth. Low levels of adiponectin and high levels of leptin predicted externalizing symptoms. Total symptom difficulties were associated with a higher leptin-to-adiponectin ratio. Our findings suggest that adipocytokines may be an important set of biomarkers to consider as underlying mechanisms contributing to developmental psychopathology.

RESUMO

The gut microbiome plays major roles in modulating host physiology. One such function is colonization resistance, or the ability of the microbial collective to protect the host against enteric pathogens1-3, including enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7, an attaching and effacing (AE) food-borne pathogen that causes severe gastroenteritis, enterocolitis, bloody diarrhea, and acute renal failure (hemolytic uremic syndrome)4,5. Although gut microbes can provide colonization resistance by outcompeting some pathogens or modulating host defense provided by the gut barrier and intestinal immune cells, this phenomenon remains poorly understood. Emerging evidence suggests that small-molecule metabolites produced by the gut microbiota may mediate this process6.

We further find that these Trp metabolites act through DRD2 to decrease expression of a host actin regulatory protein involved in C. rodentium and EHEC attachment to the gut epithelium via formation of actin pedestals. Previously identified mechanisms of colonization resistance either directly affect the pathogen by competitive exclusion or indirectly by modulation of host defense mechanisms9,10, so our results delineate a noncanonical colonization resistance pathway against AE pathogens featuring an unconventional role for DRD2 outside the nervous system in controlling actin cytoskeletal organization within the gut epithelium. Our findings may inspire prophylactic and therapeutic approaches for improving gut health and treating gastrointestinal infections, which afflict millions globally.

RESUMO

Novel variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continue to emerge as the coronavirus disease 2019 (COVID-19) pandemic extends into its fourth year. Understanding SARS-CoV-2 circulation in university populations is vital for effective interventions in higher education settings and will inform public health policy during pandemics. In this study, we performed whole-genome sequencing of 537 of 1717 SARS-CoV-2-positive nasopharyngeal/nasal swab samples collected over a nearly 20-month period from two university populations in Wisconsin, USA. We observed that the viral sequences were distributed into 57 lineages/sub-lineages belonging to 15 clades, of which the majority were from 21K (omicron, 36.13 %) and 21J (delta, 30.91 %). Nearly 40 % (213) of the sequences were omicron, of which BA.1 and its eight descendent lineages accounted for 91 %, while the remaining belonged to BA.2 and its six descendent lineages. Independent analysis of the sequences from these two universities revealed significant differences in the circulating SARS-CoV-2 variants. Phylogenetic analysis of university sequences with a global sub-dataset demonstrated that the sequences of the same lineages from the university populations were more closely related. Genome-based analysis of closely related strains, along with phylogenetic clusters and mutational differences, identified that potential virus transmission occurred within and between universities, as well as between the university and the local community. Although this study improves our understanding of the distinct transmission patterns of circulating variants in local universities, expanding genomic surveillance capacity will aid local jurisdictions not only in identifying emerging SARS-CoV-2 variants, but also in improving data-driven public health mitigation and policy efforts.

RESUMO

In an effort to elucidate new factors that may contribute to developmental psychopathology, the current study examined whether accelerated epigenetic aging at birth related to children's differential susceptibility to the effects of aversive parenting on early emerging mental health risk. Using data from a multiethnic birth cohort, the interaction between Horvath's methylation age in umbilical cord blood and hostile parenting behaviors was examined in relation to perceptions of infant's temperament at 6 months and to children's psychological symptoms at 3 years in 154 families. Results broadly revealed that children with higher levels of accelerated methylation aging evinced more unpredictable temperaments and more psychological symptoms if their mothers reported more hostile parenting, but showed fewer difficulties if mothers engaged in less hostile parenting; children with lower levels of accelerated methylation age did not show associations between hostility and temperament or psychological symptoms. Effects were not accounted for by gestational age at birth, demographic factors, or the distribution of cell subtypes. These findings suggest that accelerated epigenetic age may function as a form of differential susceptibility, signaling increased risk for psychopathology in more aversive contexts but decreased risk in less aversive early environments. Taken together, they point to a novel biological process to consider within risk for psychopathology.

RESUMO

Objectives: Gun violence in the USA is a pressing social and public health issue. As rates of gun violence continue to rise, deaths resulting from such violence rise as well. School shootings, in particular, are at their highest recorded levels. In this study, we examined rates of intentional firearm deaths, mass shootings, and school mass shootings in the USA using data from the past 5 years, 2017-2022, to assess trends and reappraise prior examination of this issue. Methods: Extant data regarding shooting deaths from 2017 through 2020 were obtained from the Centers for Disease Control and Prevention, National Center for Injury Prevention and Control, the web-based injury statistics query and reporting system (WISQARS), and, for school shootings in particular (2017-2022), from Everytown Research & Policy. Results: The number of intentional firearm deaths and the crude death rates increased from 2017 to 2020 in all age categories; crude death rates rose from 4.47 in 2017 to 5.88 in 2020. School shootings made a sharp decline in 2020-understandably so, given the onset of the COVID-19 pandemic and subsequent government or locally mandated school shutdowns-but rose again sharply in 2021. Conclusions: Recent data suggest continued upward trends in school shootings, school mass shootings, and related deaths over the past 5 years. Notably, gun violence disproportionately affects boys, especially Black boys, with much higher gun deaths per capita for this group than for any other group of youth. Implications for policy and practice are provided.

RESUMO

BACKGROUND: Adolescents with type 1 diabetes (T1D) are at high risk for elevated diabetes distress, which greatly impacts diabetes management, glycemic outcomes and overall quality of life. Developing protective skills and "resilience resources" to navigate adversity and manage diabetes distress has high potential to help adolescents with T1D achieve optimal behavioral, psychological, and health outcomes. The "Promoting Resilience in Stress Management" (PRISM) program is a manualized, brief, skills-based intervention delivered over 6 months via two 45-60 min one-on-one sessions and a family meeting with a PRISM coach, and supplemented by booster calls and a digital app. This trial (PRISM versus usual care)is designed to:: (1) assess PRISM's impact on glycemic outcomes and diabetes distress among adolescents with T1D, and (2) explor PRISM's impact on resilience, self-reported adherence, and quality of life. METHODS: We describe the protocol for a multi-site randomized controlled trial designed for adolescents ages 13-18 with elevated diabetes distress. The primary trial outcomes are glycemic outcomes and diabetes distress 6 months post-randomization. Secondary outcomes include resilience, self-reported adherence, and QOL 6 months post-randomization. Our hypothesis is that youth in the PRISM group will demonstrate better glycemic outcomes and improved diabetes distress, adherence, resilience, and QOL compared to usual care. CONCLUSIONS: This study will provide methodologically rigorous data and evidence regarding a novel intervention to promote resilience among adolescents with T1D and elevated diabetes distress. This research has the potential to offer a practical, skills-based curriculum designed to improve outcomes for this high-risk group. TRIAL REGISTRATION: Prospectively registered at Clinicaltrials.gov (NCT03847194).
