RESUMEN

PURPOSE: Acquired brain injuries (ABIs) can have devastating effects on children and their families. Families living in rural communities experience unique barriers to receiving and coordinating care for complex medical needs, but little research has examined those barriers for rural youth with ABIs. MATERIALS AND METHODS: This qualitative study explored the experiences of rural adults caring for children with ABIs through interviews with six caregivers, three school staff members, and three medical professionals who had treated at least one child with an ABI. RESULTS: Themes in their accounts include difficulty navigating complex situations, support from small communities, isolation and loneliness, the need for more professional education about ABI, and feelings of hope. Barriers to quality care coordination include navigating complex situations, access to transportation, and a lack of communication and education from healthcare agencies. Facilitators of rural care coordination include support from small communities and interagency communication. CONCLUSIONS: The results support the need for more comprehensive coordination among rural agencies involved in ABI care. Suggestions for care improvement include providing flexibility due to transportation barriers, capitalizing on the benefits of a small and caring community, and providing healthcare and education professionals with more education about ABI interventions.


Practitioners should implement tailored support systems that include initiatives to facilitate direct communication between rural medical agencies and schools.Expanding the role of care coordinators to bridge gaps across healthcare, education, and community services could enhance care coordination for children with acquired brain injuries in rural areas.Schools in rural areas should develop formal reintegration programs tailored to the needs of children with mild acquired brain injuries, leveraging existing sports protocols for non-sports-related injuries.Collaborative efforts between schools, medical teams, and community agencies can provide comprehensive education programs tailored to the rural context.The development of online options for follow-up appointments would be particularly beneficial in rural areas, where transportation barriers are more pronounced.

RESUMEN

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease, encompasses steatosis and metabolic dysfunction-associated steatohepatitis (MASH), leading to cirrhosis and hepatocellular carcinoma. Preclinical MASLD research is mainly performed in rodents; however, the model that best recapitulates human disease is yet to be defined. We conducted a wide-ranging retrospective review (metabolic phenotype, liver histopathology, transcriptome benchmarked against humans) of murine models (mostly male) and ranked them using an unbiased MASLD 'human proximity score' to define their metabolic relevance and ability to induce MASH-fibrosis. Here, we show that Western diets align closely with human MASH; high cholesterol content, extended study duration and/or genetic manipulation of disease-promoting pathways are required to intensify liver damage and accelerate significant (F2+) fibrosis development. Choline-deficient models rapidly induce MASH-fibrosis while showing relatively poor translatability. Our ranking of commonly used MASLD models, based on their proximity to human MASLD, helps with the selection of appropriate in vivo models to accelerate preclinical research.

RESUMEN

PURPOSE: Sexual debut in early adolescence is associated with poor health outcomes in adulthood. We examined the associations of social capital within families, schools, and neighborhoods with early sexual debut. METHODS: Using data from the Healthy Passages cohort, a longitudinal multilevel study of adolescents, we performed a series of cross-classified multilevel logistic regression models to examine (1) the relative contribution of schools and neighborhoods to the variance and (2) the association of markers of social cohesion/social capital in families, schools, and neighborhoods with sexual debut by 10th grade. RESULTS: There were 4,001 youth participants nested in 115 schools and 751 neighborhoods, with a high degree of cross-classification (1,340 unique combinations of school and neighborhoods). In models adjusting for individual demographics, neighborhoods contributed more to the variance (log odds U [95% confidence interval {CI}] [intra class correlation {ICC}%]) in sexual debut than schools: Uneighborhoods = 0.11 (0.02, 0.23) [3.2%] versus Uschools = 0.07 (0.01, 0.16) [2%]. Restriction of dating and family cohesion, markers of family social capital, were associated with reduced odds of sexual debut by 10th grade (odds ratio = 0.45 95% CI: 0.41-0.49 and 0.93, 95% CI: 0.86, 1.00). Neighborhood cohesion and education level were associated with early debut. Although reduced, there remained significant, unexplained variance in both the school and neighborhood level in the fully adjusted model (Uschool = 0.08 [0.01, 0.17] [2.3%], Uneighborhood = 0.08 [0.02, 0.17] [2.2%]). DISCUSSION: Markers of social capital at the family and neighborhood levels were associated with sexual debut by 10th grade. Developers of public health programs aiming to delay sexual debut should consider family-focused and neighborhood-focused interventions.

RESUMEN

For many adult human organs, tissue regeneration during chronic disease remains a controversial subject. Regenerative processes are easily observed in animal models, and their underlying mechanisms are becoming well characterized1-4, but technical challenges and ethical aspects are limiting the validation of these results in humans. We decided to address this difficulty with respect to the liver. This organ displays the remarkable ability to regenerate after acute injury, although liver regeneration in the context of recurring injury remains to be fully demonstrated. Here we performed single-nucleus RNA sequencing (snRNA-seq) on 47 liver biopsies from patients with different stages of metabolic dysfunction-associated steatotic liver disease to establish a cellular map of the liver during disease progression. We then combined these single-cell-level data with advanced 3D imaging to reveal profound changes in the liver architecture. Hepatocytes lose their zonation and considerable reorganization of the biliary tree takes place. More importantly, our study uncovers transdifferentiation events that occur between hepatocytes and cholangiocytes without the presence of adult stem cells or developmental progenitor activation. Detailed analyses and functional validations using cholangiocyte organoids confirm the importance of the PI3K-AKT-mTOR pathway in this process, thereby connecting this acquisition of plasticity to insulin signalling. Together, our data indicate that chronic injury creates an environment that induces cellular plasticity in human organs, and understanding the underlying mechanisms of this process could open new therapeutic avenues in the management of chronic diseases.

RESUMEN

BACKGROUND: Care coordination aligns services and optimizes outcomes for children with traumatic brain injury (TBI), yet numerous obstacles can impede effective care coordination following a TBI. OBJECTIVE: The goal of this work is to identify barriers and facilitators to care coordination from the perspective of individuals who care for young people impacted by TBI (e.g., medical providers, educators, caregivers). METHODS: Twenty-one care providers participated in semi-structured interviews to gather their perspectives on systems of care coordination for youth with TBI and potential areas for improvement. Using reflexive thematic analysis, researchers identified key themes across interviews. RESULTS: Three themes were identified: 1) gaps in knowledge; 2) poor collaboration and communication between systems and care providers; and 3) inadequate legislative and policy frameworks that fund and support pediatric TBI. Across themes, participants shared their experiences and ideas to improve each of these areas. CONCLUSION: A structured, consistent, and coordinated system of care for pediatric TBI is critical to ensure optimal outcomes. Protocols that emphasize intentional and productive collaboration between healthcare settings and schools and education for all care providers are cornerstones in improving outcomes for children. Top-down action that develops policy and funding initiatives is needed to ensure equitable, consistent access to appropriate healthcare and educational supports.

RESUMEN

BACKGROUND: In Oregon in 2019, only 261 students were eligible for special education under the traumatic brain injury (TBI) category. Many students with TBIs are not treated by a medical provider, so the requirement for a medical statement could prevent eligible youth from receiving special education services. OBJECTIVE: This study investigated barriers to using a medical statement to establish special education eligibility for TBI, support for using a guided credible history interview (GCHI), and training needs around GCHI. RESULTS: Among participants, 84% reported difficulty obtaining a medical statement for TBI eligibility determination, and 87% favored the GCHI as an alternative, though they reported a need for training in TBI and GCHI. CONCLUSION: The results support the use of GCHI to establish special education eligibility for TBI and informed Oregon's addition of GCHI to TBI special education eligibility determination.

RESUMEN

Splenomegaly in the context of liver disease is classically associated with advanced cirrhosis and portal hypertension.1 More recently, we observed an increasing number of patients with splenomegaly and nonalcoholic fatty liver disease (NAFLD), but in whom intensive work-up revealed no evidence of advanced liver disease or portal hypertension. In this study, we found no correlation between spleen size and histological stage of NAFLD, and a strong correlation between body weight, height and serum high density lipoprotein (HDL) levels.

RESUMEN

Preventing SARS-CoV-2 infection by modulating viral host receptors, such as angiotensin-converting enzyme 2 (ACE2)1, could represent a new chemoprophylactic approach for COVID-19 that complements vaccination2,3. However, the mechanisms that control the expression of ACE2 remain unclear. Here we show that the farnesoid X receptor (FXR) is a direct regulator of ACE2 transcription in several tissues affected by COVID-19, including the gastrointestinal and respiratory systems. We then use the over-the-counter compound z-guggulsterone and the off-patent drug ursodeoxycholic acid (UDCA) to reduce FXR signalling and downregulate ACE2 in human lung, cholangiocyte and intestinal organoids and in the corresponding tissues in mice and hamsters. We show that the UDCA-mediated downregulation of ACE2 reduces susceptibility to SARS-CoV-2 infection in vitro, in vivo and in human lungs and livers perfused ex situ. Furthermore, we reveal that UDCA reduces the expression of ACE2 in the nasal epithelium in humans. Finally, we identify a correlation between UDCA treatment and positive clinical outcomes after SARS-CoV-2 infection using retrospective registry data, and confirm these findings in an independent validation cohort of recipients of liver transplants. In conclusion, we show that FXR has a role in controlling ACE2 expression and provide evidence that modulation of this pathway could be beneficial for reducing SARS-CoV-2 infection, paving the way for future clinical trials.

RESUMEN

BACKGROUND: For students with traumatic brain injury (TBI), the COVID-19 pandemic exacerbated challenges they were already experiencing at school. METHODS: This qualitative study employed focus groups and interviews with students, parents, school, and medical personnel to explore the school experiences of students with TBI. Thematic qualitative analyses were used. RESULTS: Key themes from the analysis include (a) incidence of brain injuries decreased; (b) screen time for students with TBI exacerbated symptoms; (c) COVID protocols at school made it difficult for educators to identify and provide accommodations for students with TBI; (d) COVID protocols at school could inadvertently exacerbate mental health difficulties after a TBI; and (e) COVID-related logistics increased the time between an injury and return to school or return to play. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: The results from this study suggest that professional development for teachers supporting students with TBI is needed, especially for online learning environments. Additionally, because mental/behavioral health concerns may arise for students with TBI in online learning environments, school health care providers can work with families to assess a student's mental health, making referrals to appropriate supports. CONCLUSIONS: There is a significant need for professional development and school-wide infrastructure supportive of students with TBI.

RESUMEN

PURPOSE: The first vaccine against SARS-CoV-2 (COVID-19) for adolescents 16 years and older in the United States received Emergency Use Authorization in December 2020. Soon after its approval, parents expressed concerns about vaccine safety for adolescents. Similar concerns about vaccine safety partially explain suboptimal human papillomavirus (HPV) vaccine uptake. This qualitative study explores similarities and differences in parents' attitudes about these two vaccines. METHODS: Parents were recruited through social media and at health centers in Alabama. Semi-structured interviews with parents of adolescents aged 9-17 years were conducted before and after Alabama expanded age eligibility to those 16 and older. Topics included knowledge about HPV and COVID-19 vaccines, and parents' intentions to have children vaccinated. Interviews were analyzed using thematic analysis. RESULTS: From March 11, 2021 to April 24, 2021, 21 in-depth interviews were conducted. Parents discussed the importance of HPV and COVID-19 vaccines for protecting their children's health but differences between the two related to community protection. Parents were concerned about vaccine safety but media coverage about the COVID-19 vaccine led to more favorable attitudes about the benefits of vaccination, which was not observed for HPV vaccines. Instead for HPV vaccination, parents wanted their healthcare providers' opinions about the vaccine before making a vaccination decision. DISCUSSION: Parents had similar concerns about HPV and COVID-19 vaccines. Although provider recommendations can improve vaccine uptake, local news reports were seen to have a positive impact on COVID-19 vaccine acceptance in lieu of provider recommendation. Disseminating information online could be beneficial to promote HPV and COVID-19 vaccines.

RESUMEN

BACKGROUND: Chlamydia vaccines are currently under development and have the potential to lower the incidence of infection and disease, which are highest among adolescents and young adults. Ideally, a chlamydia vaccine would be administered to adolescents before sexual debut, a time when parents are the primary vaccine decision makers. This study explores parent opinions about an adolescent chlamydia vaccine to understand barriers and facilitators to uptake. METHODS: Semistructured interviews were conducted with parents of adolescents. Topics included conversations parents have with their children about chlamydia, opinions on chlamydia vaccine development, and vaccine characteristics, such as efficacy and cost. Interviews were analyzed using a thematic analysis approach. RESULTS: From March to April 2021, 21 interviews were completed. Few parents discuss chlamydia with their children and sex education was seen as limited. Overall, 16 parents indicated that a chlamydia vaccine is needed. However, there were mixed opinions about vaccinating their own children, related to the need to vaccinate at a young age, vaccine efficacy, and confusion about benefits of vaccination. Finally, healthcare provider recommendations were seen as important before deciding to vaccinate a child. CONCLUSIONS: Although parents think that chlamydia vaccines are needed, lack of awareness about infections and potential benefits of vaccination could serve as barriers to uptake. Healthcare provider recommendations can help to improve knowledge and vaccine uptake. However, there is a need for multilevel approaches to improve chlamydia awareness and ensure that vaccination initiation and completion rates remain high.

RESUMEN

BACKGROUND: Chlamydia vaccination is a potentially important strategy to prevent infections and reduce the global burden of disease. Ideally, chlamydia immunization programs would require vaccinating adolescents before they engage in sexual activity. Communication by health care providers (HCPs) has been shown to have an impact on vaccine acceptance. Therefore, it is imperative to understand their opinions on chlamydia vaccines and factors that would promote strong vaccine recommendations to patients to promote uptake. METHODS: Semi-structured interviews with adolescent HCPs were conducted and focused on perceived need for chlamydia vaccine. Additional topics included vaccine characteristics, such as efficacy, cost, and booster vaccines, and potential vaccine recommendation strategies. RESULTS: From January to July 2021, 22 interviews were completed. Health care providers discussed how chlamydia vaccines are needed, especially in settings with high prevalence rates. Health care providers thought a chlamydia vaccine would need to be very efficacious in preventing infections and related sequalae and cost-effective. However, there were concerns about low completion rates if this vaccine required multiple doses or boosters. In addition, vaccine misinformation was prevalent among HCPs regarding potential benefits of vaccination. CONCLUSIONS: Health care providers' perceptions that an adolescent chlamydia vaccine would be beneficial offers great promise for future promotion. However, there is need for targeted education programs about chlamydia and the benefits of vaccination for HCPs. These programs will be especially important in order for HCPs to effectively communicate about the benefits of vaccination to parents and adolescents provide strong vaccine recommendations.

RESUMEN

INTRODUCTION: Chronic pain and disability are now well-recognised long-term complications of blunt chest wall trauma. Limited research exists regarding therapeutic interventions that can be used to address these complications. A recent feasibility study was completed testing the methods of a definitive trial. This protocol describes the proposed definitive trial, the aim of which is to investigate the impact of an early exercise programme on chronic pain and disability in patients with blunt chest wall trauma. METHODS/ANALYSIS: This mixed-methods, multicentre, parallel randomised controlled trial will run in four hospitals in Wales and one in England over 12-month recruitment period. Patients will be randomised to either the control group (routine physiotherapy input) or the intervention group (routine physiotherapy input plus a simple exercise programme completed individually by the patient). Baseline measurements including completion of two surveys (Brief Pain Inventory and EuroQol 5-dimensions, 5-Levels) will be obtained on initial assessment. These measures and a client services receipt inventory will be repeated at 3-month postinjury. Analysis of outcomes will focus on rate and severity of chronic pain and disability, cost-effectiveness and acceptability of the programme by patients and clinicians. Qualitative feedback regarding acceptability will be obtained through patient and clinician focus groups. ETHICS/DISSEMINATION: London Riverside Research Ethics Committee (Reference number: 21/LO/0782) and the Health Research Authority granted approval for the trial in December 2021. Patient recruitment will commence in February 2022. Planned dissemination is through publication in a peer-reviewed Emergency Medicine Journal, presentation at appropriate conferences and to stakeholders at professional meetings. TRIAL REGISTRATION NUMBER: ISRCTN65829737; Pre-results.

RESUMEN

BACKGROUND: Mutations in the ABCB4 gene are associated with failure of bile acid emulsification leading to cholestatic liver disease. Presentations range from progressive familial intrahepatic cholestasis type 3 (PFIC3) in childhood, to milder forms seen in adulthood. AIMS: We sought to characterize adult disease with particular reference to histology which has been hitherto poorly defined. METHODS: Four unrelated adults (three female, mean age 39 years) and three sisters presenting with cholestatic liver disease in adulthood, associated with variants in the ABCB4 gene, were identified. Clinical review and detailed blinded histopathological analysis were performed. RESULTS: Two novel pathogenic ABCB4 variants were identified: c.620 T > G, p.(Ile207Arg) and c.2301dupT, p.(Thr768TyrfsTer26). Sub-phenotypes observed included low-phospholipid-associated cholelithiasis syndrome (LPAC), intrahepatic cholestasis of pregnancy (ICP), drug-induced cholestasis, idiopathic adulthood ductopenia, and adult PFIC3. Of note, 5/7 had presented with gallstone complications (4 meeting LPAC definition) and 4/6 females had a history of ICP. Considerable overlap was observed phenotypically and liver transplantation was required in 3/7 of patients. Histologically, cases generally demonstrated ductopenia of the smaller tracts, mild non-ductocentric portal inflammation, bilirubinostasis, significant copper-associated protein deposition, and varying degrees of fibrosis. CONCLUSIONS: Adults with ABCB4 mutations may harbor a spectrum of cholestatic disease phenotypes and can progress to liver transplantation. We observed a distinct histological pattern which differs from classical biliary disease and describe two novel pathogenic ABCB4 variants. ABCB4 sequencing should be considered in patients with relevant cholestatic phenotypes and/or suggestive histology; accurate diagnosis can guide potential interventions to delay progression and inform family screening.

RESUMEN

RNF43/ZNRF3 negatively regulate WNT signalling. Both genes are mutated in several types of cancers, however, their contribution to liver disease is unknown. Here we describe that hepatocyte-specific loss of Rnf43/Znrf3 results in steatohepatitis and in increase in unsaturated lipids, in the absence of dietary fat supplementation. Upon injury, Rnf43/Znrf3 deletion results in defective hepatocyte regeneration and liver cancer, caused by an imbalance between differentiation/proliferation. Using hepatocyte-, hepatoblast- and ductal cell-derived organoids we demonstrate that the differentiation defects and lipid alterations are, in part, cell-autonomous. Interestingly, ZNRF3 mutant liver cancer patients present poorer prognosis, altered hepatic lipid metabolism and steatohepatitis/NASH signatures. Our results imply that RNF43/ZNRF3 predispose to liver cancer by controlling the proliferative/differentiation and lipid metabolic state of hepatocytes. Both mechanisms combined facilitate the progression towards malignancy. Our findings might aid on the management of those RNF43/ZNRF3 mutated individuals at risk of developing fatty liver and/or liver cancer.

RESUMEN

In England, care to support people living at home is largely commissioned by local authorities (statutory organisations with responsibility for social care in specific localities) from non-statutory home-care providers (for-profit, not-for-profit, voluntary). This paper explores how managers of these services perceive commissioning arrangements and their impact on home-care providers, the care workforce and service users. Little formal research of providers' experiences of working with local authorities in a commissioning model is available. A qualitative study employed semi-structured telephone interviews with 20 managers of for-profit home-care providers from 10 selected local authority areas in England. Data were analysed using thematic analysis to identify main and subsidiary themes. Home-care providers reported operating in a complex and changeable partnership with commissioners, characterised by: (a) relationships ranging from transactional to collaborative, (b) providers expressing a strong sense of public service motivation, (c) commissioning practices that were complex to negotiate, time-consuming and overly prescriptive, (d) frequent changes in commissioning practices and a perceived lack of strategic planning, which were reported as contributing to uncertainty and tension for providers and confusion for service users. Attempting to operate a market model with tightly prescribed contracts is likely to be unsustainable. An alternative approach based on a collaborative model of joint responsibility for providing home care is recommended drawing on a conceptual framework of principal-steward relationships in contracting.

RESUMEN

Shortage of school psychologists in the USA jeopardizes the capacity of schools to meet the needs of struggling students. The aim of the study was to evaluate the progression of school psychologists through the professional preparation-to practice pipeline for attracting, preparing, and retaining school psychologists. Descriptive research methods were used to retrospectively track three annual cohorts of graduate students from eight school psychology programs as they progressed through key milestones in their preparation and early professional practice. The results indicate that a large percentage of students completed their graduate program and continued to work in the field 1-, 3-, and 5-year post-internship for a sample that was predominately White and female. The implications of the study reinforce previous calls for graduate programs to engage in targeted, personalized efforts for recruiting graduate students with minoritized cultural identities to better meet the needs of students from culturally and linguistically diverse backgrounds.

RESUMEN

Objective: In the United States, 26,534 young women (≤45 years) were diagnosed with breast cancer in 2017. Young African American (AA) women have higher incidence and mortality rates than Whites and Hispanics. Yet, few published studies describe survivorship (life after breast cancer diagnosis) experiences among this group. Here, we explore the lived experience of young AA breast cancer survivorship (via quality of life [QOL]).Design: This phenomenological study was framed by the QOL Applied to Breast Cancer model. Fifteen young AA survivors from the Southern U. S. participated in two semi-structured interviews. Methods of transcendental phenomenology were used for data collection and analysis.Results: Five themes emerged from participants' (mean age = 35 years; survivorship = 4 years) descriptions of survivorship experience: (1) actively managing spiritual self, (2) actively managing physical self, (3) actively managing psychological self, (4) actively managing social self, and (5) seeking survivorship knowledge. Participants perceived survivorship as a labile 'new normal' and 'ongoing struggle,' in which spirituality and survivorship knowledge were key to restructuring their lives.Conclusions: Survivorship among young AA survivors was more fluid and complex than the QOL model explained. Findings describe young AA breast cancer survivorship and indicate areas of potential strengths and distress. Healthcare providers and ancillary staff must exercise cultural competence to assess and anticipate young AA survivors' needs and concerns. Implementing targeted survivorship interventions, accounting for cultural contexts (e.g. high spirituality) and need for age-specific survivorship information, may improve QOL among young AA survivors.

RESUMEN

BACKGROUND: Chronic and complex medical issues, including traumatic brain injuries (TBIs), have significant educational implications. The purpose of this study was to identify and summarize the literature on care coordination strategies among health care professionals, educators, and caregivers for children with special health care needs (CSHCN). Clarifying factors that influence care coordination for CSHCN can inform future studies on care coordination for students with TBI. Improved understanding of these factors may lead to better communication, reduction of unmet needs, more efficient service access, and improved long-term outcomes for children. METHODS: A scoping review was conducted, guided by PRISMA-ScR methodology. Five databases (CINAHL, PSYCINFO, EMBASE, ERIC, PubMed) were searched to identify relevant studies that focused on care coordination and educational settings. RESULTS: Twelve articles met inclusion criteria. Care coordination interventions for CSHCN used in educational settings focused on relationship-building strategies, clear procedures and roles, and education of members of the school community. CONCLUSIONS: Findings highlight strategies to coordinate care for CSHCN and factors that may moderate effects of these interventions. Key stakeholders should now study these strategies specifically in children with TBI.
