"There's always something, and then there's more": a qualitative examination of how virtual peer led self-management can create community around the evolving SCI experience.

Introduction: Self-management programs for spinal cord injury (SCI) are a growing adjunct to traditional healthcare services aiding individuals with SCI in learning and managing symptoms and medical care. A benefit of self-management programs is that they can be facilitated by peers, offering a unique lived experience of adjusting to and managing SCI. While a growing body of literature highlights the effectiveness of peer led programs, there is limited understanding of how individuals engage with peer programs or critical components of peer support. The current study seeks to understand how individuals engaged with peers in the context of a self-management program. Methods: Secondary qualitative analysis of online forum posts resultant from a peer led self-management course for SCI. Results: Content analysis revealed several themes of how participants engaged with members of the group, including skill building, resource sharing, and problem solving. A process level theme of emotional connection to others living with similar SCI-related challenges was defined as "bearing witness." Participants commented frequently that groups were the first time they engaged with a community with lived experience, and shared experience was frequently highlighted in the responses from individuals as one of the most unique and important aspects of the intervention. Discussion: Themes identified suggest that bearing witness was a critical component of peer led intervention. While self-management content provided structure for engagement and discussion, participants report that connectedness and shared experience made content more impactful and relevant. Future research should examine if alignment of peer and participant experience increases the impact of interventions and explore if this theme is important for other chronic medical populations.

Loss of Intracellular Fibroblast Growth Factor 14 (iFGF14) Increases the Excitability of Mature Hippocampal and Cortical Pyramidal Neurons.

Mutations in FGF14 , which encodes intracellular fibroblast growth factor 14 (iFGF14), have been linked to spinocerebellar ataxia type 27 (SCA27), a multisystem disorder associated with progressive deficits in motor coordination and cognitive function. Mice ( Fgf14 -/- ) lacking iFGF14 display similar phenotypes, and we have previously shown that the deficits in motor coordination reflect reduced excitability of cerebellar Purkinje neurons, owing to the loss of iFGF14-mediated regulation of the voltage-dependence of inactivation of the fast transient component of the voltage-gated Na + (Nav) current, I NaT . Here, we present the results of experiments designed to test the hypothesis that loss of iFGF14 also attenuates the intrinsic excitability of mature hippocampal and cortical pyramidal neurons. Current-clamp recordings from adult mouse hippocampal CA1 pyramidal neurons in acute in vitro slices, however, revealed that repetitive firing rates were higher in Fgf14 -/- , than in wild type (WT), cells. In addition, the waveforms of individual action potentials were altered in Fgf14 -/- hippocampal CA1 pyramidal neurons, and the loss of iFGF14 reduced the time delay between the initiation of axonal and somal action potentials. Voltage-clamp recordings revealed that the loss of iFGF14 altered the voltage-dependence of activation, but not inactivation, of I NaT in CA1 pyramidal neurons. Similar effects of the loss of iFGF14 on firing properties were evident in current-clamp recordings from layer 5 visual cortical pyramidal neurons. Additional experiments demonstrated that the loss of iFGF14 does not alter the distribution of anti-Nav1.6 or anti-ankyrin G immunofluorescence labeling intensity along the axon initial segments (AIS) of mature hippocampal CA1 or layer 5 visual cortical pyramidal neurons in situ . Taken together, the results demonstrate that, in contrast with results reported for neonatal (rat) hippocampal pyramidal neurons in dissociated cell culture, the loss of iFGF14 does not disrupt AIS architecture or Nav1.6 localization/distribution along the AIS of mature hippocampal (or cortical) pyramidal neurons in situ .

The TELEhealth Shared decision-making Coaching and Navigation in Primary carE (TELESCOPE) intervention: a study protocol for delivering shared decision-making for lung cancer screening by patient navigators.

Background Lung cancer screening (LCS) can reduce lung cancer mortality but has potential harms for patients. A shared decision-making (SDM) conversation about LCS is required by the Centers for Medicare & Medicaid Services (CMS) for LCS reimbursement. To overcome barriers to SDM in primary care, this protocol describes a telehealth decision coaching intervention for LCS in primary care clinics delivered by patient navigators. The objective of the study is to evaluate the effectiveness of the intervention and its implementation potential, compared with an enhanced usual care (EUC) arm. Methods Patients (n = 420) of primary care clinicians (n = 120) are being recruited to a cluster randomized controlled trial. Clinicians are randomly assigned to 1) TELESCOPE intervention: prior to an upcoming non-acute clinic visit, patients participate in a telehealth decision coaching session about LCS delivered by trained patient navigators and nurse navigators place a low-dose CT scan (LDCT) order for each TELESCOPE patient wanting LCS, or 2) EUC: patients receive enhanced usual care from a clinician. Usual care is enhanced by providing clinicians in both arms with access to a Continuing Medical Education (CME) webinar about LCS and an LCS discussion guide. Patients complete surveys at baseline and 1-week after the scheduled clinic visit to assess quality of the SDM process. Re-navigation is attempted with TELESCOPE patients who have not completed the LDCT within 3 months. One month before being due for an annual screening, TELESCOPE patients whose initial LCS showed low-risk findings are randomly assigned to receive a telehealth decision coaching booster session with a navigator or no booster. Electronic health records are abstracted at 6, 12 and 18 months after the initial decision coaching session (TELESCOPE) or clinic visit (EUC) to assess initial and annual LCS uptake, imaging results, follow-up testing for abnormal findings, cancer diagnoses, treatment, and tobacco treatment referrals. This study will evaluate factors that facilitate or interfere with program implementation using mixed methods. Discussion We will assess whether a decision coaching and patient navigation intervention can feasibly support high-quality SDM for LCS and guideline-concordant LCS uptake for patients in busy primary care practices serving diverse patient populations. Trial Registration: This study was registered at ClinicalTrials.gov (NCT05491213) on August 4, 2022.

Sex Specific Associations of Sex hormone With Brain Volumes and Cerebral Blood Flow: A Cross Sectional Observational Study Within the Look AHEAD Type 2 Diabetes Cohort.

Trial Registration: NCT00017953 Background : Females have greater brain volume and cerebral blood flow than males when controlling for intracranial volume and age. Brain volume decreases after menopause, suggesting a role of sex hormones. We studied the association of sex hormones with brain volume, white matter hyperintensity volumes and cerebral blood flow in people with Type 2 Diabetes and with overweight and obesity conditions that accelerate brain atrophy. Methods : We analyzed data from 215 participants with overweight or obesity and Type 2 Diabetes from the Look AHEAD Brain Magnetic Resonance Imaging ancillary study (mean age 68 years, 73% postmenopausal female). Estradiol and total testosterone levels were measured with electrochemoluminescence assays. The ratio of brain measurements to intracranial volume was analyzed to account for body size. We analyzed sex hormones as quantitative measures in males, whereas in females we grouped those with detectable vs. undetectable hormone levels (Estradiol <73 pmol/L [20 pg/mL]: 79%; Total Testosterone < 0.07 mmol/L [0.02 ng/mL]: 37% undetectable in females). Results : Females with detectable total testosterone levels had higher brain volume to intracranial volume ratio (median [25 th , 75 th percentile]: 0.85 [0.84, 0.86]) as compared to those with undetectable Total Testosterone levels (0.84 [0.83, 0.86]; rank sum p=0.04). This association was attenuated after age and body mass index adjustment (p=0.08). Neither white matter hyperintensity volumes or cerebral blood flow in females, nor any brain measures in males, were significantly associated with Estradiol or Total Testosterone. Conclusions : In postmenopausal females with Type 2 Diabetes with overweight and obesity, detectable levels of total testosterone were associated greater brain volume relative to intracranial volume, suggesting a protective role for testosterone in female brain health. Our findings are limited by a small sample size and low sensitivity of hormone assays. Our suggestive findings can be combined with future larger studies to assess clinically important differences. Trial Registration: NCT00017953.

Identifying factors associated with physical therapy use versus non-use among injured workers with back pain in Washington State.

BACKGROUND: There is little information about predictors of physical therapy (PT) use among injured workers with back pain. The primary objective of this study is to investigate the associations between PT use and baseline factors not routinely captured in workers' compensation (WC) data. METHODS: We conducted a secondary analysis using the Washington State Workers' Compensation Disability Risk Identification Study Cohort, which combines self-reported surveys with claims data from the Washington State Department of Labor and Industries State Fund. Workers with an accepted or provisional WC claim for back injury between June 2002 and April 2004 were eligible. Baseline factors for PT use were selected from six domains (socio-demographic, pain and function, psychosocial, clinical, health behaviors, and employment-related). The outcome was a binary measure for PT use within 1 year of injury. Bivariate and multivariable logistic regression models were conducted to evaluate the associations between PT use and baseline factors. RESULTS: Among the 1370 eligible study participants, we identified 673 (49%) who received at least one PT service. Baseline factors from five of the six domains (all but health behaviors) were associated with PT use, including gender, income, pain and function measures, injury severity rating, catastrophizing, recovery expectations, fear avoidance, mental health score, body mass index, first provider seen for injury, previous injury, and several work-related factors. CONCLUSION: We identify baseline factors that are associated with PT use, which may be useful in addressing disparities in access to care for injured workers with back pain in a WC system.

Differences in weight-loss outcomes among race-gender subgroups by behavioural intervention delivery mode: An analysis of the POWER trial.

Prior in-person behavioural intervention studies have documented differential weight loss between men and women and by race, with Black women receiving the least benefit. Remotely delivered interventions are now commonplace, but few studies have compared outcomes by race-gender groups and delivery modality. We conducted a secondary analysis of POWER, a randomized trial (NCT00783315) designed to determine the effectiveness of 2 active, lifestyle-based, weight loss interventions (remote vs. in-person) compared to a control group. Participants with obesity and at least one cardiovascular disease risk factor (N = 415) were recruited in the Baltimore, MD area. Data from 233 white and 170 Black individuals were used for this analysis. Following an intention-to-treat approach, we compared the mean percent weight loss at 24 months by race-gender subgroups using repeated-measures, mixed-effects models. Everyone lost weight in the active interventions however, weight loss differed by race and gender. white and Black men had similar results for both interventions (white: in-person (-7.6%) remote (-7.4%); Black: in-person (-4.7%) remote (-4.4%)). In contrast, white women lost more weight with the in-person intervention (in-person (-7.2%) compared to the remote (-4.4%)), whereas Black women lost less weight in the in-person group compared to the remote intervention at 24 months (-2.0% vs. -3.0%, respectively; p for interaction <.001). We found differences between the effectiveness of the 2 weight loss interventions-in-person or remote-in white and Black women at 24 months. Future studies should consider intervention modality when designing weight loss interventions for women.

Recombinational exchange of M-fibril and T-pilus genes generates extensive cell surface diversity in the global group A Streptococcus population.

Among genes present in all group A streptococci (GAS), those encoding M-fibril and T-pilus proteins display the highest levels of sequence diversity, giving rise to the two primary serological typing schemes historically used to define strain. A new genotyping scheme for the pilin adhesin and backbone genes is developed and, when combined with emm typing, provides an account of the global GAS strain population. Cluster analysis based on nucleotide sequence similarity assigns most T-serotypes to discrete pilin backbone sequence clusters, yet the established T-types correspond to only half the clusters. The major pilin adhesin and backbone sequence clusters yield 98 unique combinations, defined as "pilin types." Numerous horizontal transfer events that involve pilin or emm genes generate extensive antigenic and functional diversity on the bacterial cell surface and lead to the emergence of new strains. Inferred pilin genotypes applied to a meta-analysis of global population-based collections of pharyngitis and impetigo isolates reveal highly significant associations between pilin genotypes and GAS infection at distinct ecological niches, consistent with a role for pilin gene products in adaptive evolution. Integration of emm and pilin typing into open-access online tools (pubmlst.org) ensures broad utility for end-users wanting to determine the architecture of M-fibril and T-pilus genes from genome assemblies.IMPORTANCEPrecision in defining the variant forms of infectious agents is critical to understanding their population biology and the epidemiology of associated diseases. Group A Streptococcus (GAS) is a global pathogen that causes a wide range of diseases and displays a highly diverse cell surface due to the antigenic heterogeneity of M-fibril and T-pilus proteins which also act as virulence factors of varied functions. emm genotyping is well-established and highly utilized, but there is no counterpart for pilin genes. A global GAS collection provides the basis for a comprehensive pilin typing scheme, and online tools for determining emm and pilin genotypes are developed. Application of these tools reveals the expansion of structural-functional diversity among GAS via horizontal gene transfer, as evidenced by unique combinations of surface protein genes. Pilin and emm genotype correlations with superficial throat vs skin infection provide new insights on the molecular determinants underlying key ecological and epidemiological trends.

[The Place of Groin, Colson and McGregor Flaps in the Acute Care of Deep Burns to the Hand Dorsum : A Series of 6 Cases In Lille's Burn Centre]. / Place Des Lambeaux Inguinaux Et Des Empochements Dans La Prise En Charge Aiguë Des Brûlures Profondes Du Dorsum De Main: Série De 6 Cas Au Centre De Traitement Des Brûlés De Lille.

The acute management of deep burns to the dorsum of the hand and fingers represents a challenge for the reconstructive surgeon. The exposure of osteo-tendinous structures often requires flap coverage, in a context where loco-regional or free flaps are not always feasible. The aims of reconstruction are to preserve a maximum of digital length, provide supple tissue, obtain protective sensitivity, and achieve a functional hand at 1 year. We report here on a series of 8 deep burns to the dorsum of the hand. Six hands were covered by Colson abdominal flap-graft and two by pedicled inguinal flap. Four out of 6 patients were reviewed in consultation, 1 patient was lost to follow-up, and 1 patient died. Clinical evaluation was performed by a surgeon other than the operator. Functional results are highly variable. Coverage time varies according to lesion depth and patient severity. Flap weaning took place at an average of 30 days. DASH scores ranged from 17.5 to 93/100, with average to poor total active motion (TAM) scores. The aesthetic result was satisfactory, with a Vancouver score of 4.5/13 on average, and an overall patient opinion of 3.75/10 on the POSAS scale. For deep burns to the dorsum of the hand and fingers, local flaps are rarely possible, and loco-regional flaps are not feasible in cases of associated upper limb damage. For medium to large surface areas, pedicled inguinal flaps and pocketing are two reliable techniques. Nevertheless, they require relative immobilization of the upper limb, which leads to stiffness. The question of digital pinning in the intrinsic or straight position remains unresolved, and does not appear to prevent secondary deformities. There is also a learning curve for these two flaps, even though they are reputed to be easy to lift. McGregor's flap or pocketing can be weighed against free flaps. However, the operating time is long, the surgical technique is complex, and vascular damage is common in the burn patient population. Although there have been enormous technical advances since their descriptions, the pedicled inguinal flap and pocketing remain alternatives to be considered in the acute management of deep burns to the dorsum of the hand. In this presentation, we propose a surgical management algorithm to situate these two techniques in the plastic surgeon's therapeutic armament.

Effect of Isocaloric, Time-Restricted Eating on Body Weight in Adults With Obesity : A Randomized Controlled Trial.

BACKGROUND: Time-restricted eating (TRE) lowers body weight in many studies. Whether TRE induces weight loss independent of reductions in calorie intake, as seen in rodent studies, is unknown. OBJECTIVE: To determine the effect of TRE versus a usual eating pattern (UEP) on body weight in the setting of stable caloric intake. DESIGN: Randomized, isocaloric feeding study. (ClinicalTrials.gov: NCT03527368). SETTING: Clinical research unit. PARTICIPANTS: Adults with obesity and prediabetes or diet-controlled diabetes. INTERVENTION: Participants were randomly assigned 1:1 to TRE (10-hour eating window, 80% of calories before 1 p.m.) or UEP (≤16-hour window, ≥50% of calories after 5 p.m.) for 12 weeks. Both groups had the same nutrient content and were isocaloric with total calories determined at baseline. MEASUREMENTS: Primary outcome was change in body weight at 12 weeks. Secondary outcomes were fasting glucose, homeostatic model assessment for insulin resistance (HOMA-IR), glucose area under the curve by oral glucose tolerance test, and glycated albumin. We used linear mixed models to evaluate the effect of interventions on outcomes. RESULTS: All 41 randomly assigned participants (mean age, 59 years; 93% women; 93% Black race; mean BMI, 36 kg/m2) completed the intervention. Baseline weight was 95.6 kg (95% CI, 89.6 to 101.6 kg) in the TRE group and 103.7 kg (CI, 95.3 to 112.0 kg) in the UEP group. At 12 weeks, weight decreased by 2.3 kg (CI, 1.0 to 3.5 kg) in the TRE group and by 2.6 kg (CI, 1.5 to 3.7 kg) in the UEP group (average difference TRE vs. UEP, 0.3 kg [CI, -1.2 to 1.9 kg]). Change in glycemic measures did not differ between groups. LIMITATION: Small, single-site study; baseline differences in weight by group. CONCLUSION: In the setting of isocaloric eating, TRE did not decrease weight or improve glucose homeostasis relative to a UEP, suggesting that any effects of TRE on weight in prior studies may be due to reductions in caloric intake.

Exercise and QUality diet After Leukemia (EQUAL): A randomized weight loss trial among adult survivors of childhood leukemia in the Childhood Cancer Survivor Study.

BACKGROUND: Obesity is prevalent in childhood cancer survivors and interacts with cancer treatments to potentiate risk for cardiovascular (CV) death. We tested a remote weight-loss intervention that was effective among adults with CV risk factors in a cohort of adult survivors of childhood acute lymphoblastic leukemia (ALL) with overweight/obesity. METHODS: In this phase 3 efficacy trial, survivors of ALL enrolled in the Childhood Cancer Survivor Study with body mass index (BMI)≥25 kg/m2 were randomized to a remotely-delivered weight-loss intervention versus self-directed weight loss, stratified by history of cranial radiotherapy (CRT). The primary endpoint was the difference in weight loss at 24-months in an intent-to-treat analysis. Analyses were performed using linear mixed effects models. RESULTS: Among 358 survivors (59% female, median attained age: 37 years, IQR: 33-43), baseline mean (SD) weight was 98.6 kg (24.0) for the intervention group (n=181) and 94.9 kg (20.3) for controls (n=177). Adherence to the intervention was poor; 15% of individuals in the intervention completed 24/30 planned coaching calls. Weight at 24-months was available for 274 (77%) participants. After controlling for CRT, sex, race/ethnicity, and age, the mean (SE) change in weight from baseline to 24-months was -0.4 kg (0.8) for intervention and 0.2 kg (0.6) for control participants (p=0.59). CONCLUSIONS: A remote weight-loss intervention that was successful among adults with CV conditions did not result in significant weight loss among adult survivors of childhood ALL. IMPACT: Future interventions in this population must be tailored to the unique needs of survivors to encourage engagement and adherence.

Opsin expression varies across larval development and taxa in pteriomorphian bivalves.

Introduction: Many marine organisms have a biphasic life cycle that transitions between a swimming larva with a more sedentary adult form. At the end of the first phase, larvae must identify suitable sites to settle and undergo a dramatic morphological change. Environmental factors, including photic and chemical cues, appear to influence settlement, but the sensory receptors involved are largely unknown. We targeted the protein receptor, opsin, which belongs to large superfamily of transmembrane receptors that detects environmental stimuli, hormones, and neurotransmitters. While opsins are well-known for light-sensing, including vision, a growing number of studies have demonstrated light-independent functions. We therefore examined opsin expression in the Pteriomorphia, a large, diverse clade of marine bivalves, that includes commercially important species, such as oysters, mussels, and scallops. Methods: Genomic annotations combined with phylogenetic analysis show great variation of opsin abundance among pteriomorphian bivalves, including surprisingly high genomic abundance in many species that are eyeless as adults, such as mussels. Therefore, we investigated the diversity of opsin expression from the perspective of larval development. We collected opsin gene expression in four families of Pteriomorphia, across three distinct larval stages, i.e., trochophore, veliger, and pediveliger, and compared those to adult tissues. Results: We found larvae express all opsin types in these bivalves, but opsin expression patterns are largely species-specific across development. Few opsins are expressed in the adult mantle, but many are highly expressed in adult eyes. Intriguingly, opsin genes such as retinochrome, xenopsins, and Go-opsins have higher levels of expression in the later larval stages when substrates for settlement are being tested, such as the pediveliger. Conclusion: Investigating opsin gene expression during larval development provides crucial insights into their intricate interactions with the surroundings, which may shed light on how opsin receptors of these organisms respond to various environmental cues that play a pivotal role in their settlement process.

Occupational therapy students' perceptions of their experience in a role-emerging Level II fieldwork within higher education student services.

BACKGROUND: Role-emerging settings - those where occupational therapy (OT) services have not traditionally been provided - are common sites for practice placements of entry-level occupational therapy students. A growing body of literature has attempted to determine the value and drawbacks of such practice placements on the professional preparedness of OT students with mixed findings. Benefits have been identified, including increased cultural understanding, advocacy, creativity, initiative, and problem-solving skills. However, OT students have been reported to perceive such placement as limiting their professional growth and preparedness to practice compared to traditional placements. METHODS: A phenomenological study was conducted seeking the perceptions of OT students (n = 14) about their clinical placement at a role-emerging site. Recorded semi-structured interviews were conducted by trained interviewers within two weeks of the end of clinical placement. The recordings were transcribed verbatim and then coded using an iterative multi-coder inductive approach. Inter-coder agreement, reflectivity, and audit trail were maintained. RESULTS: Three themes emerged from the analysis: (1) integrating independence and support, (2) becoming occupational therapists, and (3) filling a gap. These themes reflect students' positive perceptions of their role-emerging clinical placement. They felt that this placement allowed them to develop self-confidence and professional identity as occupational therapists and learn new skills while simultaneously filling a gap in services for clients. Most importantly, they felt that this placement prepared them for their future OT practice. CONCLUSION: This finding and their resounding support of the experience suggest that OT students can perceive role-emerging placement as a solid foundation for clinical practice. Factors, included in this placement, that may have contributed to their experience include the level of support provided, time available for learning including space to make mistakes, and freedom from productivity and payor requirements.

Forward and Back is Not Enough: Applying Best Practices for Translation of Pediatric Sleep Questionnaires.

Cultural differences in the experience of sleep warrant consideration in the measurement of sleep across populations. This requires careful attention to both language and culture when translating survey measures. While forward and back translation is the most commonly used approach, it has numerous limitations if used as an isolated method. Best practice guidelines recommend a multi-step team-based approach for translating questionnaires. We present our recent experience applying best practices in a study with both Spanish and English-speaking Mexican American mothers of toddlers. This work is part of a larger project that will measure parental sleep-related beliefs and parenting practices in Mexican American parents of toddlers. We utilized a team-based approach to translation and cultural adaptation, assembling a diverse, bilingual, and bicultural team. The translation process started with items and measures that we had selected, revised as needed, or created. New items were based on constructs identified in semi-structured interviews and focus groups used to explore parental sleep-related beliefs and parenting practices in the target population. Following this, our translation process included forward and back translation, harmonization and decentering, cognitive interviewing, debriefing, adjudication, and proofreading. We outline details of our process and the rationale for each step. We also highlight how each step contributes to ensuring culturally appropriate items with conceptual equivalence across languages. To ensure inclusivity and scientific rigor within the field of sleep research, investigators must utilize best practices for translations and cultural adaptations, building on the foundation of cultural constructs often identified in qualitative work.

Identifying priority areas to support primary care engagement in breast cancer survivorship care: A Delphi study.

INTRODUCTION: Existing approaches in cancer survivorship care delivery have proven to be insufficient to engage primary care. This study aimed to identify stakeholder-informed priorities to improve primary care engagement in breast cancer survivorship care. METHODS: Experts in U.S. cancer survivorship care delivery were invited to participate in a 4-round online Delphi panel to identify and evaluate priorities for defining and fostering primary care's engagement in breast cancer survivorship. Panelists were asked to identify and then assess (ratings of 1-9) the importance and feasibility of priority items to support primary care engagement in survivorship. Panelists were asked to review the group results and reevaluate the importance and feasibility of each item, aiming to reach consensus. RESULTS: Respondent panelists (n = 23, response rate 57.5%) identified 31 priority items to support survivorship care. Panelists consistently rated three items most important (scored 9) but with uncertain feasibility (scored 5-6). These items emphasized the need to foster connections and improve communication between primary care and oncology. Panelists reached consensus on four items evaluated as important and feasible: (1) educating patients on survivorship, (2) enabling screening reminders and monitoring alerts in the electronic medical record, (3) identifying patient resources for clinicians to recommend, and (4) distributing accessible reference guides of common breast cancer drugs. CONCLUSION: Role clarity and communication between oncology and primary care were rated as most important; however, uncertainty about feasibility remains. These findings indicate that cross-disciplinary capacity building to address feasibility issues may be needed to make the most important priority items actionable in primary care.

Framework for an interprofessional experience addressing health and disability for health professional students.

BACKGROUND AND PURPOSE: A Health and Disabilities Interprofessional Education (IPE) course was implemented to join three healthcare disciplines together to collaboratively plan, implement, and reflect on professional roles and responsibilities. The goal and purpose of this course was to create an advancement of interprofessional education and practice within health science professions early in their students' programs utilizing innovative teaching methods working directly with individuals with disabilities. EDUCATIONAL ACTIVITY AND SETTING: 72 students were assigned to interprofessional teams of 10-11 people. Through asynchronous and synchronous learning activities, student teams worked together to plan and conduct community-based client interviews. FINDINGS: Quantitative and qualitative evaluation methods were used to explore the impact of interprofessional experiential learning experiences. Qualitative data showed a greater awareness and understanding of the different roles and responsibilities in interprofessional teams as well as a greater appreciation for the value of interacting with persons with disabilities (PWD) during their training. Quantitative data showed a significant change in students' understanding of their roles and responsibilities as a member of an interprofessional team, their confidence with working with PWD in a future healthcare capacity, as well as their understanding of how the social determinants of health may influence the healthcare experience of a PWD. SUMMARY: Interprofessional education and experiential learning opportunities are good ways to facilitate "real" patient care experiences and team roles and responsibilities. This enables healthcare students to practice communication, build relationships, and understand the lived experience of their patients.

α-catenin middle- and actin-binding domain unfolding mutants differentially impact epithelial strength and sheet migration.

α-catenin (α-cat) displays force-dependent unfolding and binding to actin filaments through direct and indirect means, but features of adherens junction structure and function most vulnerable to loss of these allosteric mechanisms have not been directly compared. By reconstituting an α-cat F-actin-binding domain unfolding mutant known to exhibit enhanced binding to actin (α-cat-H0-FABD+) into α-cat knockout Madin Darby Canine Kidney (MDCK) cells, we show that partial loss of the α-cat catch bond mechanism (via an altered H0 α-helix) leads to stronger epithelial sheet integrity with greater colocalization between the α-cat-H0-FABD+ mutant and actin. α-cat-H0-FABD+ -expressing cells are less efficient at closing scratch-wounds, suggesting reduced capacity for more dynamic cell-cell coordination. Evidence that α-cat-H0-FABD+ is equally accessible to the conformationally sensitive α18 antibody epitope as WT α-cat and shows similar vinculin recruitment suggests this mutant engages lower tension cortical actin networks, as its M-domain is not persistently open. Conversely, α-cat-M-domain salt-bridge mutants with persistent recruitment of vinculin and phosphorylated myosin light chain show only intermediate monolayer adhesive strengths, but display less directionally coordinated and thereby slower migration speeds during wound-repair. These data show α-cat M- and FABD-unfolding mutants differentially impact cell-cell cohesion and migration properties, and suggest signals favoring α-cat-cortical actin interaction without persistent M-domain opening may improve epithelial monolayer strength through enhanced coupling to lower tension actin networks.

Construction of relatedness matrices in autopolyploid populations using low-depth high-throughput sequencing data.

KEY MESSAGE: An improved estimator of genomic relatedness using low-depth high-throughput sequencing data for autopolyploids is developed. Its outputs strongly correlate with SNP array-based estimates and are available in the package GUSrelate. High-throughput sequencing (HTS) methods have reduced sequencing costs and resources compared to array-based tools, facilitating the investigation of many non-model polyploid species. One important quantity that can be computed from HTS data is the genetic relatedness between all individuals in a population. However, HTS data are often messy, with multiple sources of errors (i.e. sequencing errors or missing parental alleles) which, if not accounted for, can lead to bias in genomic relatedness estimates. We derive a new estimator for constructing a genomic relationship matrix (GRM) from HTS data for autopolyploid species that accounts for errors associated with low sequencing depths, implemented in the R package GUSrelate. Simulations revealed that GUSrelate performed similarly to existing GRM methods at high depth but reduced bias in self-relatedness estimates when the sequencing depth was low. Using a panel consisting of 351 tetraploid potato genotypes, we found that GUSrelate produced GRMs from genotyping-by-sequencing (GBS) data that were highly correlated with a GRM computed from SNP array data, and less biased than existing methods when benchmarking against the array-based GRM estimates. GUSrelate provides researchers with a tool to reliably construct GRMs from low-depth HTS data.

Advancing the care of individuals with cancer through innovation & technology: Proceedings from the cardiology oncology innovation summit 2020 and 2021.

As cancer therapies increase in effectiveness and patients' life expectancies improve, balancing oncologic efficacy while reducing acute and long-term cardiovascular toxicities has become of paramount importance. To address this pressing need, the Cardiology Oncology Innovation Network (COIN) was formed to bring together domain experts with the overarching goal of collaboratively investigating, applying, and educating widely on various forms of innovation to improve the quality of life and cardiovascular healthcare of patients undergoing and surviving cancer therapies. The COIN mission pillars of innovation, collaboration, and education have been implemented with cross-collaboration among academic institutions, private and public establishments, and industry and technology companies. In this report, we summarize proceedings from the first two annual COIN summits (inaugural in 2020 and subsequent in 2021) including educational sessions on technological innovations for establishing best practices and aligning resources. Herein, we highlight emerging areas for innovation and defining unmet needs to further improve the outcome for cancer patients and survivors of all ages. Additionally, we provide actionable suggestions for advancing innovation, collaboration, and education in cardio-oncology in the digital era.

Status of the Health Promoting University (HPU) globally and its relevance for emerging African HPUs: an integrative review and bibliometric analysis.

BACKGROUND: The Health Promoting Universities (HPU) concept is undertheorized, with no African university belonging to the International Network of Health Promoting Universities (IHPU). AIM: The study aimed to investigate the status of the HPU concept globally to inform emerging HPUs, more specifically in Africa, regarding its implementation. METHODS: An integrative literature review of studies conducted between 1 January 2013 and 5 November 2023 was conducted from online databases (PubMed, Scopus, Web of Science, Lilacs, CINAHL and Medline). A VOS bibliometric analysis viewer was used to extract and analyze further relevant information that could have been missed in the review. RESULTS: From 1128 records, 22 (N = 22) articles including two reports met the inclusion criteria. The main findings were that: (1) the HPU network is growing as a global network though undertheorized and less reported on, (2) the implementation of the HPU depends on a plethora of underpinning philosophies such as salutogenic and whole systems approach, and diverse programs and initiatives, 3) the terms HPU and healthy universities are often used interchangeably but the whole systems approach appears to be consistent in many HPU interventions. However, five contextual challenges that emanated from this review were discussed, including the definition of the HPU concept, theories for the HPU concept, measurement of the HPU concept, coordination and methods for measuring the HPU concept status. These challenges present obstacles to measuring the status of the HPU concept beyond the number of affiliated universities and HPU initiatives. CONCLUSION: Despite the challenges, the HPU concept is gaining momentum globally, as evidenced by the growing list of universities (HPU network) involved and the proliferation of interventions/initiatives targeting university students.

Mental health screening in pediatric lower limb deficiency population.

BACKGROUND: Youth with lower limb deficiency (LLD) may be at increased risk for mental health difficulties. However, guidelines around psychosocial screening are not well established. OBJECTIVE: To describe the implementation and results of a mental health screening process in a multidisciplinary prosthetics clinic. DESIGN: Survey. SETTING: Outpatient specialty care clinic located within a children's hospital. PATIENTS: All patients ages 0-18 years with LLD seen at a monthly multidisciplinary prosthetics clinic between September 2019 and January 2023 (n = 75). INTERVENTIONS: Not applicable. MAIN OUTCOMES MEASURES: Quality of life was measured by the Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric proxy survey. Psychological functioning was measured using the Strengths and Difficulties Questionnaire (SDQ). RESULTS: Descriptive statistics were used to determine the proportion of patients who endorsed clinically significant concerns. Of the 75 clinic visits during the study time frame, the psychosocial screeners were completed at 38 (51%). A total of 25 unique patients completed the screeners; 12 patients completed the screener more than once. The most commonly endorsed concerns on the PROMIS were issues with physical mobility (65%) and upper extremity function (40%). The SDQ revealed that a majority (62.5%) of the screened patients had an overall score above the clinical cutoff, indicating psychosocial distress in more than one area. The most commonly reported mental health concern was peer problems (62.5%). Post hoc analysis of repeat screenings indicated that most problems identified during the first screening persisted at follow-up screenings. CONCLUSIONS: Clinically significant psychological concerns were common among the sample, indicating the need to address this aspect of patients' well-being. Preliminary data on repeat screenings suggest that clinically significant concerns may not self-resolve. Routine psychosocial screening is critical for early identification of mental health problems and timely referral to evidence-based psychological interventions.
