RÉSUMÉ

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.In multiple myeloma (MM), measurable residual disease (MRD) is assessed in bone marrow (BM). However, less invasive evaluation of peripheral residual disease (PRD) in blood could be advantageous and less cumbersome. We investigated the prognostic value of PRD monitoring after 24 cycles of maintenance in 138 transplant-eligible patients with MM enrolled in the GEM2012MENOS65/GEM2014MAIN clinical trials. PRD was assessed using next-generation flow (NGF) and mass spectrometry (MS). Positive PRD by NGF in 16/138 (11.5%) patients was associated with a 13-fold increased risk of progression and/or death; median progression-free survival (PFS) and overall survival (OS) were 2.5 and 47 months, respectively. Considering patients' MRD status in BM as the reference, PRD detection using NGF showed positive and negative predictive values of 100% and 73%, respectively. Presence of PRD helped identifying patients at risk of imminent progression among those with positive MRD in BM. Patients with undetectable PRD according to both NGF and MS showed 2-year PFS and OS rates of 97% and 100%, respectively. In multivariate analyses including the Revised International Staging System and the complete remission status, only MRD in BM and PRD by NGF showed independent prognostic value for PFS. This study supports the use of less invasive PRD monitoring during maintenance or observation in transplant-eligible patients with MM.

RÉSUMÉ

INTRODUCTION: The progression of neurologic cavovarus (NCV) and equinocavovarus (NECV) foot deformities during growth can eventually lead to non-reducible severe talonavicular (TN) and subtalar (ST) joint rotational malalignments. This study aimed to describe a technique to correct severe, resistant inversion deformity of the ST joint complex as the foundational procedure in comprehensive reconstruction of multi-segmental NCV and NECV deformities in pediatric patients and to analyze mid-term radiologic, functional, and satisfaction outcomes. METHODS: This prospective study included children with severe NCV and NECV foot deformities who underwent TCNR between 2019 and 2022, with a minimum follow-up of 2 years. Talocalcaneal angle, talus-1 metatarsal angles, and TN coverage angle were measured in preoperative and postoperative weight-bearing foot radiographs. The foot and ankle disability index, foot function index, and Maryland foot score evaluated functionality. Qualitative questions assessed perceived improvement, satisfaction, and expectations of patients/caregivers. Descriptive, comparative pre-post, subgroup, correlation, and satisfaction analysis were performed. RESULTS: Twenty-six patients (36 feet: 16 unilateral and 10 bilateral) were included; 50% were female, median age was 12.1 years (IQR, 3.21) and median follow-up was 32.9 months (IQR, 18.7). Fifty-four percent had cerebral palsy, and 23% had charcot-marie-tooth disease; 84.6% were ambulatory. Significant improvements were found in radiologic parameters and functional outcomes (P<0.01), with no relevant differences between unilateral or bilateral procedures, pathology, functional level, or ambulatory capacity (P>0.05). Correlations between radiologic parameters or functional scales with age were generally low. Most reported significant functional improvements, outcomes exceeding expectations, and high satisfaction; they would recommend the surgery and undergo the procedure again. There were 3 minor complications: hypersensitivity, partial recurrence, and undercorrection. CONCLUSIONS: The TCNR technique enables realignment of severe, resistant inversion deformity of the ST joint complex in NCV and NECV foot deformities. When combined with procedures to correct the other foot deformities and muscle imbalances, functional outcomes are enhanced, high patient/caregiver satisfaction is achieved, and low complication rates are possible. This approach represents an important modification and extension of an already described technique, the deep plantar-medial release. LEVEL OF EVIDENCE: Level III, therapeutic prospective cohort study.

RÉSUMÉ

This study explores the valorization of tea leaf waste by extracting polyphenols through reflux extraction, subsequently using them to synthesize zero-valent iron nanoparticles (nZVI). The in situ generated nanoparticles, when combined with fixed amounts of hydrogen peroxide, facilitated the removal of various dyes (methylene blue, methyl orange, and orange G) via a hetero-catalytic Fenton process. The iron nanoparticles were thoroughly characterized by gas adsorption of N2 at 77 K, scanning electron microscopy (SEM), Transmission Electron Microscopy (TEM), FT-IR spectroscopy, X-ray diffraction (XRD), and thermal analysis, including thermogravimetric analysis (TG) and temperature-programmed reduction (TPR). A statistical design of experiments and response surface methodology were employed to analyze the influence of polyphenol, Fe(III), and H2O2 concentrations on dye removal efficiency. The results demonstrated that optimizing the operational conditions could achieve 100% dye removal efficiency. This study highlights the potential of nZVI synthesized through eco-friendly methods as a promising solution for water decontamination involving diverse model dyes, thus contributing to sustainable waste management and environmental protection.

RÉSUMÉ

INTRODUCTION: Culturally and linguistically diverse (CALD) patients should but do not routinely receive professional interpretation. The authors examined provider perceptions of barriers and solutions to interpreter services (IS) in a safety-net hospital to inform quality improvement (QI). METHODS: A 13-item survey was distributed to 750 clinicians representing 10 services across professional roles, including social workers. Closed- and open-ended questions addressed accessing IS, IS value, and care for CALD patients. Respondents ranked eight barriers to routine IS use and provided ideas for improvement. Descriptive statistics characterized survey results in aggregate and by professional role and care team. Quantitative and qualitative results were triangulated for agreement between survey domains and coded free-text response themes. RESULTS: A total of 221 responses were analyzed (29.5% response rate). Cost was the lowest-ranked barrier across roles. Leading barriers were efficiency pressures and cumbersome access. Free-text responses agreed with these findings. CALD patients were perceived to have higher complication risk by 87.5% of social workers but by 56.8% of other roles. Recommendations to increase IS varied by team: streamlined access process (46.2% emergency, 37.8% inpatient respondents), expanded in-person interpretation (55.6% inpatient, 45.8% perioperative respondents), and better equipment (44.4% outpatient, 35.9% emergency, 25.0% perioperative respondents). CONCLUSION: Provider experiences vary by care team and interpretation modality. Interpretation services are cumbersome to access and compete with efficiency pressures, leading to shortcuts that fail to provide adequate language access. Three initial QI efforts resulted: increased video interpretation equipment, a new language access committee, and a new language access leadership role.

RÉSUMÉ

PURPOSE: To explore adult community members' perspectives concerning barriers to mental health care that confront rural-dwelling youth. METHODS: Group concept mapping, a participatory community-engaged research method, was used. Adult community members brainstormed and sorted statements describing barriers rural youth encounter in accessing mental health services. Point and cluster maps were created to visualize conceptual similarities between statements. Statements were rated according to their commonness and importance (1: low commonness/importance, 5: high commonness/importance). FINDINGS: Thirty-five adults sorted and/or rated 71 barriers facing rural youth in accessing mental health services. Seven conceptual clusters were identified: system-level barriers, knowledge and communication, youth concerns, parent/guardian concerns, parent/guardian barriers, costs and convenience, and school-level barriers. Within youth concerns, community members also identified a subcluster focused on stigma. Common and important statements related to limited after-school programs and community mental health support initiatives. CONCLUSIONS: Group concept mapping methodology provides structure for conceptualizing challenges facing rural youth in accessing mental health services. Policies should be informed by rural community concerns and priorities. After-school and support programs may align with mental health needs identified by rural communities.

RÉSUMÉ

The pupillary light reflex (PLR) adapts the amount of light reaching the retina, protecting it and improving image formation. Two PLR mechanisms have been described in vertebrates. First, the pretectum receives retinal inputs and projects to the Edinger-Westphal nucleus (EWN), which targets the ciliary ganglion through the oculomotor nerve (nIII). Postganglionic fibers enter the eye-globe, traveling to the iris sphincter muscle. Additionally, some vertebrates exhibit an iris-intrinsic PLR mechanism mediated by sphincter muscle cells that express melanopsin inducing muscle contraction. Given the high degree of conservation of the lamprey visual system, we investigated the mechanisms underlying the PLR to shed light onto their evolutionary origins. Recently, a PLR mediated by melanopsin was demonstrated in lampreys, suggested to be brain mediated. Remarkably, we found that PLR is instead mediated by direct retino-iridal cholinergic projections. This retina-mediated PLR acts synergistically with an iris-intrinsic mechanism that, as in other vertebrates, is mediated by melanopsin and has contribution of gap junctions between muscle fibers. In contrast, we show that lampreys lack the brain-mediated PLR. Our results suggest that two eye-intrinsic PLR mechanisms were present in early vertebrate evolution, whereas the brain-mediated PLR has a more recent origin.

RÉSUMÉ

The development of transition metal-based catalytic platforms that promote bioorthogonal reactions inside living cells remains a major challenge in chemical biology. This is particularly true for palladium-based catalysts, which are very powerful in organic synthesis but perform poorly in the cellular environment, mainly due to their rapid deactivation. We now demonstrate that grafting Pd(II) complexes into engineered ß-sheets of a model WW domain results in cell-compatible palladominiproteins that effectively catalyze depropargylation reactions inside HeLa cells. The concave shape of the WW domain ß-sheet proved particularly suitable for accommodating the metal center and protecting it from rapid deactivation in the cellular environment. A thorough NMR and computational study confirmed the formation of the metal-stapled peptides and allowed us to propose a three-dimensional structure for this novel metalloprotein motif.

RÉSUMÉ

OBJECTIVE: To determine the degree of agreement of two differents stratification models for pharmaceutical care to people living with HIV. METHODS: This was a single-centre observational prospective cohort study of patients with regular follow-up in pharmaceutical care consultations according to the Capacity-Motivation-Opportunity methodology, conducted between January 1st and March 31th, 2023. Patients received the pharmacotherapeutic interventions applied routinely to ambulatory care patients according to this model. As part of the usual clinical practice, the presence or absence of the variables that apply to both stratification models were collected. The scores obtained and the corresponding stratification level were collected for each patient according to both stratification models published (ST-2017 and ST-2022). To analyze the reliability between the measurements of two numerical score models of the stratification level with both tools, their degree of concordance was calculated using the intraclass correlation coefficient. Likewise, reliability was also evaluated from a qualitative perspective by means of Cohen's Kappa coefficient. Additionally, the existence of correlation between the scores of the two models was assessed by calculating Pearson's correlation coefficient. RESULTS: Of the total of 758 patients being followed in the cohort, finally, 233 patients were enrolled. The distribution of patients for each stratification model was: ST-2017: 59.7% level-3, 25.3% level-2 and 15.0% level-1, while for ST-2022: 60.9% level-3, 26.6% level-2 and 12.4% level-1. It was observed that the reclassification was symmetrical (p=0.317). The qualitative analysis of the agreement between the models showed a good Cohen's kappa value, (K=0.66). A value of 0.563 was found as the intraclass correlation coefficient. Finally, the correlation analysis between the quantitative scores of the two models yielded a Pearson correlation coefficient of 0.86. CONCLUSIONS: The concordance between the two models was good, which confirms that the multidimensional adaptation and simplification of the model were correct and that its use can be extended in routine clinical practice.

RÉSUMÉ

While pre-exposure prophylaxis (PrEP) has demonstrated efficacy in preventing HIV transmission, disparities in access persist in the United States, especially among Hispanic/Latinx sexual minority men (SMM). Language barriers and differences in how Latinx SMM obtain information may impact access to PrEP and HIV prevention. This study used data from the 2021 American Men's Internet Survey (AMIS) to examine differences in communication networks and PrEP use among Latinx SMM by primary language (Spanish vs. English). We examined the associations between Latinx SMM's individual- and meso-level communication networks and PrEP-related outcomes using modified Poisson regression with robust variances. Spanish-speaking Latinx SMM in the study were less likely to test for HIV, be aware of PrEP, and use daily PrEP, compared to English-speaking participants. Sexuality disclosure to a healthcare provider was positively associated with PrEP uptake among all participants and predicted STI testing over the past 12 months among English-speaking Latinx SMM. Findings highlight disparities in PrEP awareness and uptake among Latinx SMM, especially among those whose primary language is Spanish. Addressing these disparities through targeted interventions, including improved communication with healthcare providers, may help facilitate PrEP access and use in this population.

RÉSUMÉ

BACKGROUND: Clinical decision support systems (CDSSs) are computer applications, which can be applied to give guidance to practitioners in antimicrobial stewardship (AS) activities; however, further information is needed for their optimal use. OBJECTIVES: Our objective was to analyze the implementation of a CDSS program in a second-level hospital, describing alerts, recommendations, and the effects on consumption and clinical outcomes. METHODS: In October 2020, a pharmacist-driven CDSS designed for AS was implemented in a second-level hospital. The program provides a list of alerts related to antimicrobial treatment and microbiology, which were automatized for revision by the AS professionals. To analyze the implementation of the CDSS, a pre-post-intervention, retrospective study was designed. AS-triggered alerts and recommendations (total number and rate of acceptance) were compiled. The effect of the CDSS was measured using antimicrobial consumption, duration of antimicrobial treatments, in-hospital mortality, and length of stay (LOS) for patients admitted for infectious causes. RESULTS: The AS team revised a total of 7,543 alerts and 772 patients had at least one recommendation, with an acceptance rate of 79.3%. Antimicrobial consumption decreased from 691.1 to 656.8 defined daily doses (DDD)/1,000 beds-month (p = 0.04) and the duration of antimicrobial treatment from 3.6 to 3.3 days (p < 0.01). In-hospital mortality decreased from 6.6 to 6.2% (p = 0.46) and mean LOS from 7.2 to 6.2 days (p < 0.01). CONCLUSION: The implementation of a CDSS resulted in a significant reduction of antimicrobial DDD, duration of antimicrobial treatments, and hospital LOS. There was no significant difference in mortality.

RÉSUMÉ

Schizophrenia is associated with altered cortical circuitry. Although the schizophrenia risk gene NRG1 is known to affect the wiring of inhibitory interneurons, its role in excitatory neurons and axonal development is unclear. Here, we investigated the role of Nrg1 in the development of the corpus callosum, the major interhemispheric connection formed by cortical excitatory neurons. We found that deletion of Nrg1 impaired callosal axon development in vivo. Experiments in vitro and in vivo demonstrated that Nrg1 is cell-autonomously required for axonal outgrowth and that intracellular signaling of Nrg1 is sufficient to promote axonal development in cortical neurons and specifically in callosal axons. Furthermore, our data suggest that Nrg1 signaling regulates the expression of Growth Associated Protein 43, a key regulator of axonal growth. In conclusion, our study demonstrates that NRG1 is involved in the formation of interhemispheric callosal connections and provides a novel perspective on the relevance of NRG1 in excitatory neurons and in the etiology of schizophrenia.

RÉSUMÉ

BACKGROUND: Asthma is the leading source of unscheduled hospitalisation in Australian children, with a high burden placed upon children, their parents/families, and the healthcare system. In Australia, there are widening disparities in paediatric asthma care including inequitable access to comprehensive ongoing and planned asthma care for children. METHODS: The Asthma Care from Home Project is a comprehensive virtually enabled asthma model of care that aims to a. supports families, communities and healthcare providers, b. flexible and locally acceptable, and c. allow for adoption of innovations such as digital technologies so that asthma care can be provided "from home", reduce potentially preventable asthma hospitalisation, and ensure satisfaction at a patient, family, and healthcare provider level. The model of care includes standardisation of discharge care through provision of an asthma discharge resource pack containing individual asthma action plan, follow-up letters for the child's general practitioner (GP) and school/child care, and access to online asthma educational sessions and resource; post-discharge care coordination through text message reminders for families for regular GP review, email correspondence with their child's GP and school/childcare; and virtual home visits to discuss home environmental triggers, provide personalised asthma education and respond to parental concerns relating to their child's asthma. This study is comprised of three components: 1) a quasi-experimental pre/post impact evaluation assessing the impact of the model on healthcare utilisation and asthma control measures; 2) a mixed-methods implementation evaluation to understand how and why our intervention was effective or ineffective in producing systems change; 3) an economic evaluation to assess the cost-effectiveness of the proposed model of care from a family and health services perspective. DISCUSSION: This study aims to improve access to asthma care for children in rural and remote areas. Implementation evaluation and economic evaluation will provide insights into the sustainability and scalability of the asthma model of care.

RÉSUMÉ

The Strengthening Care for Children (SC4C) is a general practitioner (GP)-paediatrician integrated model of care that consists of co-consulting sessions and case discussions in the general practice setting, with email and telephone support provided by paediatricians to GPs during weekdays. This model was implemented in 21 general practices in Australia (11 Victoria and 10 New South Wales). Our study aimed to identify the factors moderating the implementation of SC4C from the perspectives of GPs, general practice personnel, paediatricians and families. We conducted a qualitative study as part of the mixed-methods implementation evaluation of the SC4C trial. We collected data through virtual and in-person focus groups at the general practices and phone, virtual and in-person interviews. Data was analysed using an iterative hybrid inductive-deductive thematic analysis. Twenty-one focus groups and thirty-seven interviews were conducted. Overall, participants found SC4C acceptable and suitable for general practices, with GPs willing to learn and expand their paediatric care role. GPs cited improved confidence and knowledge due to the model. Paediatricians reported an enhanced understanding of the general practice context and the strain under which GPs work. GPs and paediatricians reported that this model allowed them to build trust-based relationships with a common goal of improving care for children. Additionally, they felt some aspects, including the lack of remuneration and the work and effort required to deliver the model, need to be considered for the long-term success of the model. Families expressed their satisfaction with the shared knowledge and quality of care jointly delivered by GPs and paediatricians and highlighted that this model of care provides easy access to specialty services without out-of-pocket costs. Future research should focus on finding strategies to ensure the long-term Implementation of this model of care with a particular focus on the individual stressors in general practices.

RÉSUMÉ

Nanomaterials are structures with a wide range of applications in the medical, pharmaceutical, food, textile, and electronic industries, reaching more customers worldwide. As a relatively new technological field, the information about the associated risk of nanomaterials in environmental and human health must be addressed and consolidated to develop accurate legislations, frameworks, and guidelines to standardise their use in any field. This review aims to display and context the global applications of nanomaterials, their final disposal, as well as the perspective of the current efforts formulated by various countries (including Mexico and Latin American countries), international official departments and organisations directed to implement regulations on nanomaterials, nanotechnology, and nanoscience matters. In addition, the compiled information includes the tools, initiatives, and strategies to develop regulatory frameworks, such as life cycle assessments, risk assessments, technical tools, and biological models to evaluate their effects on living organisms. Finally, the authors point out the importance of implementing global regulations to promote nanotechnological research according to a precautionary principle focused on an environmental and health protection approach to ensure the use and application of nanotechnologies safely, and responsibly.

RÉSUMÉ

Cell culture devices, such as microwells and microfluidic chips, are designed to increase the complexity of cell-based models while retaining control over culture conditions and have become indispensable platforms for biological systems modelling. From microtopography, microwells, plating devices, and microfluidic systems to larger constructs such as live imaging chamber slides, a wide variety of culture devices with different geometries have become indispensable in biology laboratories. However, while their application in biological projects is increasing exponentially, due to a combination of the techniques, equipment and tools required for their manufacture, and the expertise necessary, biological and biomedical labs tend more often to rely on already made devices. Indeed, commercially developed devices are available for a variety of applications but are often costly and, importantly, lack the potential for customisation by each individual lab. The last point is quite crucial, as often experiments in wet labs are adapted to whichever design is already available rather than designing and fabricating custom systems that perfectly fit the biological question. This combination of factors still restricts widespread application of microfabricated custom devices in most biological wet labs. Capitalising on recent advances in bioengineering and microfabrication aimed at solving these issues, and taking advantage of low-cost, high-resolution desktop resin 3D printers combined with PDMS soft lithography, we have developed an optimised a low-cost and highly reproducible microfabrication pipeline. This is thought specifically for biomedical and biological wet labs with not prior experience in the field, which will enable them to generate a wide variety of customisable devices for cell culture and tissue engineering in an easy, fast reproducible way for a fraction of the cost of conventional microfabrication or commercial alternatives. This protocol is designed specifically to be a resource for biological labs with limited expertise in those techniques and enables the manufacture of complex devices across the µm to cm scale. We provide a ready-to-go pipeline for the efficient treatment of resin-based 3D-printed constructs for PDMS curing, using a combination of polymerisation steps, washes, and surface treatments. Together with the extensive characterisation of the fabrication pipeline, we show the utilisation of this system to a variety of applications and use cases relevant to biological experiments, ranging from micro topographies for cell alignments to complex multipart hydrogel culturing systems. This methodology can be easily adopted by any wet lab, irrespective of prior expertise or resource availability and will enable the wide adoption of tailored microfabricated devices across many fields of biology.

RÉSUMÉ

BACKGROUND/OBJECTIVES: Most studies about Papillon-Lefèvre syndrome (PLS) are limited to case reports and patients of the same nationality. This study aimed to determine the self-reported prevalence of signs, symptoms and treatment effectiveness in PLS patients from five Latin American countries. METHODS: An online survey was conducted among adult and paediatric patients from Mexico, Argentina, Colombia and Brazil. Data were collected using multiple-choice, open-ended and image-chooser questions on demographics, signs and symptoms, perceived treatment effectiveness and quality of life. RESULTS: Seventeen patients (10 males and 7 females) aged 4-47 years were surveyed. All had palmoplantar hyperkeratosis. Other affected sites were the feet and hand dorsum (82.35%), Achilles tendon (88.24%), forearms (58.82%), legs (29.41%) and glutes (23.53%). They frequently presented hyperhidrosis and nail pitting. Four had a history of delayed umbilical cord separation. All used topical treatments, with moderate effectiveness; half used oral retinoids, perceived as highly effective. Most reported decreased quality of life and walking difficulties. CONCLUSIONS: The study's results align with prior research on PLS, but reveal new insights, including the impact on patients' quality of life and a history of delayed umbilical cord separation. These findings warrant consideration in future research and patient care.

The aim of this systematic review is the assessment of the effect of mouth breathing on the prevalence of tongue thrust. The review was performed according to the PRISMA 2020 checklist guidelines, and the protocol was registered with PROSPERO (CRD42022339527). The inclusion criteria were the following: studies of clinical trials and cross-sectional and longitudinal descriptive studies that evaluate the appearance of tongue thrust in patients with mouth breathing; healthy subjects of any age, race or sex; and studies with a minimum sample group of five cases. The exclusion criteria were the following: studies with syndromic patients, articles from case reports, and letters to the editor and/or publisher. Searches were performed in electronic databases such as The National Library of Medicine (MEDLINE via PUBMED), the Cochrane Central Register of Controlled Trials, Web of Science and Scopus, including studies published until November 2023, without a language filter. The methodological quality of the included case-control studies was assessed using the Newcastle-Ottawa Scale (NOS), and the Joanna Briggs Institute (JBI) tool was used for descriptive cross-sectional studies and cross-sectional prevalence studies. A meta-analysis was conducted on studies that provided data on patients' classification according to mouth breathing (yes/no) as well as atypical swallowing (yes/no) using Review Manager 5.4. From 424 records, 12 articles were selected, and 4 were eligible for meta-analysis. It was shown that there is no consensus on the diagnostic methods used for mouth breathing and tongue thrust. The pooled risk ratio of atypical swallowing was significantly higher in the patients with mouth breathing (RR: 3.70; 95% CI: 2.06 to 6.66). These studies have several limitations, such as the heterogeneity among the individual studies in relation to the diagnostic tools and criteria for the assessment of mouth breathing and atypical swallowing. Considering the results, this systematic review shows that patients with mouth breathing presented higher risk ratios for atypical swallowing.

RÉSUMÉ

In contrast to humans, lampreys spontaneously recover their swimming capacity after a complete spinal cord injury (SCI). This recovery process involves the regeneration of descending axons. Spontaneous axon regeneration in lampreys has been mainly studied in giant descending neurons. However, the regeneration of neurochemically distinct descending neuronal populations with small-caliber axons, as those found in mammals, has been less studied. Cholecystokinin (CCK) is a regulatory neuropeptide found in the brain and spinal cord that modulates several processes such as satiety, or locomotion. CCK shows high evolutionary conservation and is present in all vertebrate species. Work in lampreys has shown that all CCKergic spinal cord axons originate in a single neuronal population located in the caudal rhombencephalon. Here, we investigate the spontaneous regeneration of CCKergic descending axons in larval lampreys following a complete SCI. Using anti-CCK-8 immunofluorescence, confocal microscopy and lightning adaptive deconvolution, we demonstrate the partial regeneration of CCKergic axons (81% of the number of axonal profiles seen in controls) 10 weeks after the injury. Our data also revealed a preference for regeneration of CCKergic axons in lateral spinal cord regions. Regenerated CCKergic axons exhibit colocalization with synaptic vesicle marker SV2, indicative of functional synaptic connections. We also extracted swimming dynamics in injured animals by using DeepLabCut. Interestingly, the degree of CCKergic reinnervation correlated with improved swimming performance in injured animals, suggesting a potential role in locomotor recovery. These findings open avenues for further exploration into the role of specific neuropeptidergic systems in post-SCI spinal locomotor networks.

RÉSUMÉ

BACKGROUND: In the United States, 66 million people speak a language other than English at home. Patients with diverse language needs often face significant health disparities. Information and communication technologies have expanded the realm of modalities for patient-provider communication. However, the extent to which digital language access tools are utilized by healthcare providers is unknown. This research examines provider perspectives on language assistance techniques and the role of communication technology when serving patients with non-English language preference (NELP). METHODS: Between April and July 2019, an online survey was administered to 3,033 healthcare providers (doctors, nurse practitioners, pharmacists, and dentists) in Washington State. Providers reported on their language access practices and perspectives on communication technology. RESULTS: Most providers reported using ad hoc language access techniques when engaging patients with NELP, such as a patient's family member or friend (75.8%), a patient's child specifically (61.9%), or a bilingual staff member (64.3%). Professional techniques, such as in-person interpretation (53.5%), phone interpretation (57%), and video remote interpretation (38.8%), were used less often. Dissatisfaction with the language access processes of healthcare providers' place of work was associated with a higher reliance on a patient's family or friend for language interpretation. CONCLUSIONS: Findings suggest that providers might be under-utilizing professional and digital interpreter services while relying on ad hoc techniques. Such practices reveal systemic constraints on language access that might make it difficult for providers to access timely and reliable options for professional language interpretation, despite federal regulations that mandate such services for patients with NELP.
