RESUMO

The prevalence of severe obesity among adolescents continues to be a significant global concern. Metabolic and bariatric surgery (MBS) has increasingly shown to produce safe, efficacious, and durable effects on weight loss and related physical health complications, and evidence of psychosocial outcomes are beginning to mature. The revised American Society for Metabolic and Bariatric Surgery pediatric guidelines published in 2018 reported emergent data regarding key psychosocial outcomes, including mental health, disordered eating, and quality of life, although data were limited by small, short-term studies and often without comparison groups. The purpose of this narrative review was to expand the relevant findings regarding youth with severe obesity who receive MBS to further clarify the impact of surgery on psychosocial outcomes.

RESUMO

Sleep is a complex and conserved biological process that affects several body functions and behaviors. Evidence suggests that there is a reciprocal interaction between sleep and immunity. For instance, fragmented sleep can increase the probability of parasitic infections and reduce the ability to fight infections. Moreover, viral and bacterial infections alter the sleep patterns of infected individuals. However, the effects of macro-parasitic infections on sleep remain largely unknown, and measuring sleep in non-model organisms remains challenging. In this study, we investigated whether macro-parasite infections could alter sleep-like behavior of their hosts. We experimentally infected three-spined sticklebacks (Gasterosteus aculeatus), a freshwater fish, with the tapeworm Schistocephalus solidus and used a hidden Markov model to characterize sleep-like behavior in sticklebacks. One to four days after parasite exposure, infected fish showed no difference in sleep-like behavior compared with non-exposed fish, and fish that were exposed-but-not-infected only showed a slight reduction in sleep-like behavior during daytime. Twenty-nine to 32 days after exposure, infected fish showed more sleep-like behavior than control fish, while exposed-but-not-infected fish showed overall less sleep-like behavior. Using brain transcriptomics, we identified immune- and sleep-associated genes that potentially underlie the observed behavioral changes. These results provide insights into the complex association between macro-parasite infection, immunity, and sleep in fish and may thus contribute to a better understanding of reciprocal interactions between sleep and immunity.

RESUMO

PURPOSE: A caregiver is generally required for a patient to proceed with allogeneic hematopoietic cell transplantation (alloHCT). If continuous caregiver support is not available, alloHCT will likely not be a treatment option. A qualitative study design was used to explore caregiver requirements from the perspectives of social workers (SWs). Secondary objectives included learning about requirement flexibility, barriers, and ideas to support patients and caregivers. METHODS: Semi-structured web-based focus groups were conducted with alloHCT SWs who worked with adults at the United States (U.S.) transplant centers (TCs) from May to July 2022. Focus groups explored TC caregiver requirements, including flexibility and exceptions, origins, and barriers. RESULTS: Twenty-two SWs from TCs across the U.S. participated. All noted their TC required a caregiver to proceed to alloHCT, though there was variation in the length of time a caregiver was required and the distance needed to stay near the TC post-alloHCT. Most participants described differences within the transplant team in allowing exceptions to caregiver requirements. SWs described barriers including finances and patients needing to relocate closer to the TC. CONCLUSION: SWs reported variation in caregiver requirements across TCs. Though variation may allow for some flexibility, it may contribute to access barriers. Additional research is needed to identify essential requirements for safe post-transplant care and monitoring and to develop patient-centered models to help patients access life-saving treatment.

RESUMO

Flat bands that do not merely arise from weak interactions can produce exotic physical properties, such as superconductivity or correlated many-body effects. The quantum metric can differentiate whether flat bands will result in correlated physics or are merely dangling bonds. A potential avenue for achieving correlated flat bands involves leveraging geometrical constraints within specific lattice structures, such as the kagome lattice; however, materials are often more complex. In these cases, quantum geometry becomes a powerful indicator of the nature of bands with small dispersions. We present a simple, soft-chemical processing route to access a flat band with an extended quantum metric below the Fermi level. By oxidizing Ni-kagome material Cs2Ni3S4 to CsNi3S4, we see a two orders of magnitude drop in the room temperature resistance. However, CsNi3S4 is still insulating, with no evidence of a phase transition. Using experimental data, density functional theory calculations, and symmetry analysis, our results suggest the emergence of a correlated insulating state of unknown origin.

RESUMO

There are few validated contextual measures predicting adoption of evidence-based programs. Variation in context at clinical sites can hamper dissemination. We examined organizational characteristics of Veterans Affairs hospitals implementing STRIDE, a hospital walking program, and characteristics' influences on program adoption. Using a parallel mixed-method design, we describe context and organizational characteristics by program adoption. Organizational characteristics included: organizational resilience, implementation climate, organizational readiness to implement change, highest complexity sites versus others, material support, adjusted length of stay (LOS) above versus below national median, and improvement experience. We collected intake forms at hospital launch and qualitative interviews with staff members at 4 hospitals that met the initial adoption benchmark, defined as completing supervised walks with 5+ unique hospitalized Veterans during months 5 to 6 after launch with low touch implementation support. We identified that 31% (n = 11 of 35) of hospitals met adoption benchmarks. Seven percent of highest complexity hospitals adopted compared to 48% with lower complexity. Forty-three percent that received resources adopted compared to 29% without resources. Thirty-six percent of hospitals with above-median LOS adopted compared to 23% with below-median. Thirty-five percent with at least some implementation experience adopted compared to 0% with very little to no experience. Adopters reported higher organizational resilience than non-adopters (mean = 23.5 [SD = 2.6] vs 22.7 [SD = 2.6]). Adopting hospitals reported greater organizational readiness to change than those that did not (mean = 4.2 [SD = 0.5] vs 3.8 [SD = 0.6]). Qualitatively, all sites reported that staff were committed to implementing STRIDE. Participants reported additional barriers to adoption including challenges with staffing and delays associated with hiring staff. Adopters reported that having adequate staff facilitated implementation. Implementation climate did not have an association with meeting STRIDE program adoption benchmarks in this study. Contextual factors which may be simple to assess, such as resource availability, may influence adoption of new programs without intensive implementation support.

RESUMO

OBJECTIVE: To examine the relationship between site-level adaptation and early adoption of Caregivers Finding Important Resources, Support, and Training (FIRST) training during national implementation across diverse Veteran Health Administration (VA) medical centers. DATA SOURCES AND STUDY SETTING: We enrolled and evaluated 25 VA medical centers (VAMCs). Along with administrative data on site characteristics, we examined site-reported data on adaptations and intervention adoption, defined as ≥4 training classes delivered to ≥5 caregivers at 6 months from April through October 2022. STUDY DESIGN: A type III hybrid implementation-effectiveness cluster randomized controlled trial, randomized VAMCs 1:1 to receive foundational (low-touch) implementation support (n = 12) or the addition of enhanced (high-touch) implementation support (n = 13). DATA COLLECTION/EXTRACTION METHODS: At key implementation phases, VAMCs were asked to report adaptations including content, contextual modifications (format, setting, personnel, and population), and training of providers. We describe site-level adaptations by arm and by organizational characteristics that included VAMC complexity level, staffing, rurality, and organizational readiness to change. We used qualitative comparative analysis to identify unique adaptations that contributed to intervention adoption at 6 months. PRINCIPAL FINDINGS: VAMCs randomized to receive enhanced support reported slightly more adaptations than those randomized to foundational support. At 6 months, VAMCs with two or more adaptations adopted Caregivers FIRST at a higher rate than those with fewer adaptations (90% vs. 44%). Staffing adaptations (e.g., who delivered the intervention), format and content (e.g., modified delivery pace), and referring provider training were unique adaptations to adopting sites. CONCLUSIONS: Site-level adaptations were diverse and occurred more frequently in sites with early adoption of Caregivers FIRST. Future research should identify best practices of supporting and monitoring intervention adaptation. Understanding the role of adaptation in early adoption success could assist other healthcare systems in implementing interventions for caregivers.

RESUMO

BACKGROUND: There is increasing recognition of the importance of maximizing program-setting fit in scaling and spreading effective programs. However, in the context of hospital-based mobility programs, there is limited information on how settings could consider local context and modify program characteristics or implementation activities to enhance fit. To fill this gap, we examined site-initiated adaptations to STRIDE, a hospital-based mobility program for older Veterans, at eight Veterans Affairs facilities across the United States. METHODS: STRIDE was implemented at eight hospitals in a stepped-wedge cluster randomized trial. During the pre-implementation phase, sites were encouraged to adapt program characteristics to optimize implementation and align with their hospital's resources, needs, and culture. Recommended adaptations included those related to staffing models, marketing, and documentation. To assess the number and types of adaptations, multiple data sources were reviewed, including implementation support notes from site-level support calls and group-based learning collaborative sessions. Adaptations were classified based on the Framework for Reporting Adaptations and Modifications-Enhanced (FRAME), including attention to what was adapted, when, why, and by whom. We reviewed the number and types of adaptations across sites that did and did not sustain STRIDE, defined as continued program delivery during the post-implementation period. RESULTS: A total of 25 adaptations were reported and classified across seven of the eight sites. Adaptations were reported across five areas: program documentation (n = 13), patient eligibility criteria (n = 5), program enhancements (n = 3), staffing model (n = 2), and marketing and recruitment (n = 2). More than one-half of adaptations were planned. Adaptations were common in both sustaining and non-sustaining sites. CONCLUSIONS: Adaptations were common within a program designed with flexible implementation in mind. Identifying common areas of planned and unplanned adaptations within a flexible program such as STRIDE may contribute to more efficient and effective national scaling. Future research should evaluate the relationship between adaptations and program implementation.

RESUMO

To inform clinical trial design and real-world precision pediatric oncology practice, we classified diagnoses, assessed the landscape of mutations, and identified genomic variants matching trials in a large unselected institutional cohort of solid tumors patients sequenced at Dana-Farber / Boston Children's Cancer and Blood Disorders Center. Tumors were sequenced with OncoPanel, a targeted next-generation DNA sequencing panel. Diagnoses were classified according to the International Classification of Diseases for Oncology (ICD-O-3.2). Over 6.5 years, 888 pediatric cancer patients with 95 distinct diagnoses had successful tumor sequencing. Overall, 33% (n = 289/888) of patients had at least 1 variant matching a precision oncology trial protocol, and 14% (41/289) were treated with molecularly targeted therapy. This study highlights opportunities to use genomic data from hospital-based sequencing performed either for research or clinical care to inform ongoing and future precision oncology clinical trials. Furthermore, the study results emphasize the importance of data sharing to define the genomic landscape and targeted treatment opportunities for the large group of rare pediatric cancers we encounter in clinical practice.

RESUMO

Introduction: Environmental exposures and experimental manipulations can alter the ontogenetic composition of tissue-resident macrophages. However, the impact of these alterations on subsequent immune responses, particularly in allergic airway diseases, remains poorly understood. This study aims to elucidate the significance of modified macrophage ontogeny resulting from environmental exposures on allergic airway responses to house dust mite (HDM) allergen. Methods: We utilized embryonic lineage labeling to delineate the ontogenetic profile of tissue-resident macrophages at baseline and following the resolution of repeated lipopolysaccharide (LPS)-induced lung injury. We investigated differences in house dust mite (HDM)-induced allergy to assess the influence of macrophage ontogeny on allergic airway responses. Additionally, we employed single-cell RNA sequencing (scRNAseq) and immunofluorescent staining to characterize the pulmonary macrophage composition, associated pathways, and tissue localization. Results: Our findings demonstrate that the ontogeny of homeostatic alveolar and interstitial macrophages is altered after the resolution from repeated LPS-induced lung injury, leading to the replacement of embryonic-derived by bone marrow-derived macrophages. This shift in macrophage ontogeny is associated with reduced HDM-induced allergic airway responses. Through scRNAseq and immunofluorescent staining, we identified a distinct subset of resident-derived interstitial macrophages expressing genes associated with allergic airway diseases, localized adjacent to terminal bronchi, and diminished by prior LPS exposure. Discussion: These results suggest a pivotal role for pulmonary macrophage ontogeny in modulating allergic airway responses. Moreover, our findings highlight the implications of prior environmental exposures in shaping future immune responses and influencing the development of allergies. By elucidating the mechanisms underlying these phenomena, this study provides valuable insights into potential therapeutic targets for allergic airway diseases and avenues for further research into immune modulation and allergic disease prevention.

RESUMO

DNMT3A mutations are frequently found in clonal hematopoiesis and a variety of hematologic malignancies, including acute myeloid leukemia. An assortment of mouse models have been engineered to explore the tumorigenic potential and malignant lineage bias due to loss of function of DNMT3A in consort with commonly comutated genes in myeloid malignancies, such as Flt3, Nras, Kras, and c-Kit. We employed several tamoxifen-inducible Cre-ERT2 murine model systems to study the effects of constitutively active KrasG12D-driven myeloid leukemia (Kras) development together with heterozygous (3aHet) or homozygous Dnmt3a deletion (3aKO). Due to the rapid generation of diverse nonhematologic tumors appearing after tamoxifen induction, we employed a transplantation model. With pretransplant tamoxifen induction, most Kras mice died quickly of T-cell malignancies regardless of Dnmt3a status. Using posttransplant induction, we observed a dose-dependent effect of DNMT3A depletion that skewed the leukemic phenotype toward a myeloid lineage. Specifically, 64% of 3aKO/Kras mice had exclusively myeloid disease compared with 36% of 3aHet/Kras and only 13% of Kras mice. Here, 3aKO combined with Kras led to increased disease burden, multiorgan infiltration, and faster disease progression. DOT1L inhibition exerted profound antileukemic effects in malignant 3aKO/Kras cells, but not malignant cells with Kras mutation alone, consistent with the known sensitivity of DNMT3A-mutant leukemia to DOT1L inhibition. RNAseq from malignant myeloid cells revealed that biallelic Dnmt3a deletion was associated with loss of cell-cycle regulation, MYC activation, and TNF⍺ signaling. Overall, we developed a robust model system for mechanistic and preclinical investigations of acute myeloid leukemia with DNMT3A and Ras-pathway lesions.

RESUMO

INTRODUCTION: pelvic fracture in children is considered one of the most important injuries due to its high mortality. They are rare, but have a major impact on patients' functional outcomes. OBJECTIVE: to evaluate the clinical evolution and functional grade in pediatric patients with pelvic fractures who have already been treated, either conservatively or surgically. MATERIAL AND METHODS: descriptive-cross-sectional-retrospective study. Sample of 24 patients, aged five to 16 years with pelvic fracture, treated from 2016 to 2021. Clinical and functional outcome was assessed using the Barthel index and hip range of motion, as well as surgical or conservative treatment, accompanying lesions and injury mechanism. RESULTS: to find out if there is an association between the Torode and Zieg classifications with the Barthel index and hip range of motion, an association analysis was performed with the 2 statistic, obtaining a 2 value = 19.213. with p = 0.004 for the Barthel index and a 2= 14.253 with p = 0.0026 for hip ranges of motion; these results indicate that there is statistically significant association. CONCLUSION: the most frequent type of pelvic fracture in pediatric patients treated is type III on the Torode and Zieg scale, which according to the Barthel index is associated with a degree of independence and complete hip mobility arches, so the clinical and functional outcome in these patients is high in severe injuries.


INTRODUCCIÓN: la fractura de pelvis en edad pediátrica es considerada de las lesiones más importantes debido a su alta mortalidad; son poco frecuentes, pero tienen gran impacto en el resultado funcional de los pacientes. OBJETIVO: evaluar la evolución clínica y grado funcional en niños con fracturas de pelvis tratados de forma conservadora o quirúrgica. MATERIAL Y MÉTODOS: estudio descriptivo-transversal-retrospectivo. Muestra de 24 pacientes, de cinco a 16 años de edad, con fractura de pelvis, tratados del 2016 al 2021. Se valoró el resultado clínico y funcional mediante el índice de Barthel y arcos de movilidad de cadera, tratamiento quirúrgico o conservador, lesiones acompañantes y mecanismo de lesión. El análisis estadístico se realizó con el software IBM SPSS Statistics®. RESULTADOS: se realizó un análisis de asociación mediante 2 entre las clasificaciones de Torode y Zieg con el índice de Barthel y arcos de movilidad de cadera, obteniendo un valor de 2 = 19.213 con p = 0.004 para índice de Barthel y un valor de 2= 14.253 con p = 0.0026 para arcos de movilidad de cadera; estos resultados indican que hay una asociación estadísticamente significativa. CONCLUSIÓN: el tipo de fractura de pelvis más frecuente en pacientes tratados es el tipo III en la escala de Torode y Zieg, la cual, según el índice de Barthel, se asocia con un grado de independencia y arcos de movilidad de cadera completos, por lo que el resultado clínico y funcional en estos pacientes es alto en lesiones severas.

RESUMO

Background and Objectives: Pruritus is a common and disabling symptom affecting as much as 50-90% of chronic kidney disease (CKD) patients undergoing dialysis. The pruritus experienced by these patients is often resistant to common anti-pruritic agents and has an overall negative impact on quality of life. With its antioxidant property and anti-inflammatory effects, omega-3 fatty acids have been used to alleviate pruritus. The objective of this study is to assess the effect of omega-3 fatty acid supplementation in reducing the severity of pruritus among dialytic CKD patients. Methods: Various electronic databases were searched from inception to August 2022. Randomized controlled trials comparing the effect of omega-3 fatty acids versus placebo on the pruritus scores were included. The studies were independently assessed by three reviewers. Revman version 5.4 was used to analyze the data extracted from the studies while heterogeneity was evaluated using Chi2 and I2. Results: A total of four studies with a population of 166 patients were included in the meta-analysis. The results show an overall beneficial effect of omega-3 fatty acids with a standardized mean difference of -1.40 (CI -1.74 to -1.05, Z=7.95, p value <0.00001). With a Chi2 of 2.91 (p=0.41) and I2 of 0%, there was no significant heterogeneity observed in the pooled analysis. Conclusion: Overall, the results of the meta-analysis support the finding that omega-3 fatty acid supplementation may have a beneficial effect on reducing the severity of pruritus among CKD patients on dialysis.

RESUMO

ABSTRACT: There has been an increase in volume as well as an improvement in overall survival (OS) after hematopoietic cell transplantation (HCT) for hematologic disorders. It is unknown if these changes have affected racial/ethnic minorities equally. In this observational study from the Center for International Blood and Marrow Transplant Research of 79 904 autologous (auto) and 65 662 allogeneic (allo) HCTs, we examined the volume and rates of change of autoHCT and alloHCT over time and trends in OS in 4 racial/ethnic groups: non-Hispanic Whites (NHWs), non-Hispanic African Americans (NHAAs), and Hispanics across 5 2-year cohorts from 2009 to 2018. Rates of change were compared using Poisson model. Adjusted and unadjusted Cox proportional hazards models examined trends in mortality in the 4 racial/ethnic groups over 5 study time periods. The rates of increase in volume were significantly higher for Hispanics and NHAAs vs NHW for both autoHCT and alloHCT. Adjusted overall mortality after autoHCT was comparable across all racial/ethnic groups. NHAA adults (hazard ratio [HR] 1.13; 95% confidence interval [CI] 1.04-1.22; P = .004) and pediatric patients (HR 1.62; 95% CI 1.3-2.03; P < .001) had a higher risk of mortality after alloHCT than NHWs. Improvement in OS over time was seen in all 4 groups after both autoHCT and alloHCT. Our study shows the rate of change for the use of autoHCT and alloHCT is higher in NHAAs and Hispanics than in NHWs. Survival after autoHCT and alloHCT improved over time; however, NHAAs have worse OS after alloHCT, which has persisted. Continued efforts are needed to mitigate disparities for patients requiring alloHCT.

RESUMO

Polycystic ovary syndrome (PCOS) is a lifelong chronic condition that affects one in ten females and can be diagnosed in adolescence. As adolescents with PCOS transition to adulthood, counselling for lifestyle management and mental health concerns often transition from involving the family unit to increasingly individual-focused approaches. PCOS is associated with a large range of comorbidities affecting reproductive, metabolic, dermatological, and psychological health. The diagnosis and comorbidities of PCOS are influenced by pubertal hormones and need to be reassessed continuously to ensure that treatment remains appropriate for age and development. As young patients grow up, personal concerns often change, especially in relation to reproductive management. In this Review, we present prevalence rates, screening tools, and treatment recommendations for PCOS-related conditions, and we consider the diagnostic and clinical elements of optimal transition of care models that ensure continuity of comprehensive care for adolescents moving from the paediatric health-care system to the adult health-care system.

RESUMO

STUDY OBJECTIVE: To evaluate the relationship between body mass and levonorgestrel intrauterine device (LNG-IUD) expulsion in adolescents and young adults (AYA). DESIGN, SETTING, PARTICIPANTS & INTERVENTIONS: A retrospective chart review was conducted of nulliparous females aged 10-24 years who had a 52-milligram LNG-IUD placed between November 2017 and May 2021 by pediatric and adolescent gynecology providers at a tertiary children's hospital, including those who underwent metabolic and bariatric surgery (MBS). Primary analysis focused on 10-19 year olds as they had comparable anthropometrics (namely BMI percentile [BMIP] as defined by the Centers for Disease Control). Descriptive statistics included means, standard deviations (SD), and ranges for continuous variables counts and percentages for categorical variables. Chi-square or Fisher's exact tests were used to assess associations. Logistic regressions were fit to test the associations between BMIP, MBS, and the odds of expulsion. MAIN OUTCOME MEASURES & RESULTS: A total of 588 patients were included in the primary analysis (10-19 years). Mean age was 15.8 years (±2.0). Using BMIP, 15.5% (n = 91) of the sample was overweight and 22.3% (n = 131) were obese. Within 12 months, 33 patients (5.6%) experienced expulsion. Every one-unit increase in BMIP was associated with a 3% increase in the odds of expulsion (P = .008), and each increase in BMIP category (eg, overweight vs average/underweight) was significantly associated with increased odds of expulsion (OR = 2.77-4.28). Patients who had LNG-IUD placement during MBS (n = 43) had higher odds of expulsion (OR = 3.23; P = .024) than other patients. CONCLUSION: AYA with higher BMIP and/or who undergo MBS are at increased risk of LNG-IUD expulsion within one year of placement.

RESUMO

Amyotrophic lateral sclerosis (ALS) is a rare neuromuscular disease characterized by severe muscle weakness mainly due to degeneration and death of motor neurons. A peculiarity of the neurodegenerative processes is the variable susceptibility among distinct neuronal populations, exemplified by the contrasting resilience of motor neurons innervating the ocular motor system and the more vulnerable facial and hypoglossal motor neurons. The crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration. In this study, we investigated the survival of ocular, facial, and hypoglossal motor neurons utilizing the murine SOD1G93A ALS model at various stages of the disease. Our primary objective was to determine whether the survival of the different brainstem motor neurons was linked to disparate VEGF expression levels in resilient and susceptible motor neurons throughout neurodegeneration. Our findings revealed a selective loss of motor neurons exclusively within the vulnerable nuclei. Furthermore, a significantly higher level of VEGF was detected in the more resistant motor neurons, the extraocular ones. We also examined whether TDP-43 dynamics in the brainstem motor neuron of SOD mice was altered. Our data suggests that the increased VEGF levels observed in extraocular motor neurons may potentially underlie their resistance during the neurodegenerative processes in ALS in a TDP-43-independent manner. Our work might help to better understand the underlying mechanisms of selective vulnerability of motor neurons in ALS.
