RESUMO

Objectives: Pancreatic fibrosis is one of the main pathological features of chronic pancreatitis (CP), suggesting a strong relationship between CP and pancreatic ductal cancer. There was no available data about pancreatic fibrosis and pancreatic dysfunction in the early CP (ECP) using endosonography (EUS). Methods: Asymptomatic patients with pancreatic enzyme abnormalities (AP-P; n = 56) and patients with ECP (n = 21) were determined by the absence of abnormal findings on upper gastrointestinal endoscopy, abdominal ultrasonography, and abdominal computed tomography. An Olympus EUS (GF-UCT 260; Olympus) was used to perform EUS. Open software "Image J", developed by NIH, was used to measure the surface area fraction of the designated elastic blue region. The maximum value among the pancreatic head, pancreatic body, and pancreatic tail was defined as the ELST-blue score. The exocrine and endocrine pancreatic functions were evaluated using the N-benzoyl-l-tyrosyl-p-aminobenzoic acid (BT-PABA) test and homeostasis model assessment of ß-cell function (HOMA-ß) value, respectively. Results: EUS score, lobularity, and hyperechoic foci/strands in patients with ECP were significantly (p < 0.001) higher than those in patients with AP-P. In addition, there were no significant differences in the BT-PABA test (73.1 ± 25.5, 68.5 ± 15.6) and HOMA-ß (93.1 ± 67.4, 73.5 ± 139.7) between patients with ECP and AP-P. The ELST-blue score measured by image J as the quantification tool in EUS strain elastography in patients with ECP was significantly higher (p = 0.002) than that in patients with AP-P. Interestingly, the ELST-blue score was significantly associated with HOMA-ß in patients with ECP. Conclusions: The ELST-blue score may be a useful tool for the evaluation of endocrine pancreatic dysfunction in the ECP.

RESUMO

Background/Aims: In this study, we aim to develop a model for predicting gastroesophageal varices (GEV) bleeding in patients with chronic hepatitis B (CHB) by utilizing hemodynamic parameters obtained through four-dimensional flow MRI (4D flow MRI). Methods: This study conducted a prospective enrollment of CHB patients suspected of GEV from October 2021 to May 2022. The severity of varices and bleeding risk were evaluated using clinical findings and upper gastrointestinal endoscopy, and patients were classified into high-risk and non-high-risk groups. The study utilized serological examination, ultrasonographic examination, and 4D flow MRI. Relevant parameters were selected through univariate and multivariate analyses, and a prediction model was established using binary logistic regression analysis. The model was combined with the Baveno Ⅵ/Ⅶ and Expanded Baveno Ⅵ/Ⅶ criteria to evaluate diagnostic efficacy and the risk of avoiding endoscopic examination. Results: A total of 40 CHB patients were enrolled and categorized into the high-risk group (n = 15) and the non-high-risk group (n = 25). The spleen diameter and regurgitant fraction (R%) were independent predictors of variceal bleeding and a predictive model was established. The combination of this prediction model and the Baveno Ⅵ/Ⅶ criteria achieved high diagnostic efficiency, enabling 45.00% (18/40) of patients to be exempted from the unnecessary endoscopic procedure and the high-risk misclassification rate (0%) was less than 5%. Conclusion: The prediction model generated by 4D flow MRI has the potential to assess the likelihood of varices and can be supplemented by the Baveno VI/VII criteria to improve diagnostic accuracy in CHB patients.

RESUMO

Chronic social defeat stress (CSDS), a widely used rodent model of stress, reliably leads to decreased social interaction in stress susceptible animals. Here, we investigate a role for fear learning in this response using male 129 Sv/Ev mice, a strain that is more vulnerable to CSDS than the commonly used C57BL/6 strain. We first demonstrate that defeated 129 Sv/Ev mice avoid a CD-1 mouse, but not a conspecific, indicating that motivation to socialize is intact in this strain. CD-1 avoidance is characterized by approach behavior that results in running in the opposite direction, activity that is consistent with a threat response. We next test whether CD-1 avoidance is subject to the same behavioral changes found in traditional models of Pavlovian fear conditioning. We find that associative learning occurs across 10 days CSDS, with defeated mice learning to associate the color of the CD-1 coat with threat. This leads to the gradual acquisition of avoidance behavior, a conditioned response that can be extinguished with 7 days of repeated social interaction testing (5 tests/day). Pairing a CD-1 with a tone leads to second-order conditioning, resulting in avoidance of an enclosure without a social target. Finally, we show that social interaction with a conspecific is a highly variable response in defeated mice that may reflect individual differences in generalization of fear to other social targets. Our data indicate that fear conditioning to a social target is a key component of CSDS, implicating the involvement of fear circuits in social avoidance.

RESUMO

This study investigated the risk to social behavior and cognitive flexibility induced by chronic social defeat stress (CSDS) during early and late adolescence (EA and LA). Utilizing the "resident-intruder" stress paradigm, adolescent male Sprague-Dawley rats were exposed to CSDS during either EA (postnatal days 29-38) or LA (postnatal days 39-48) to explore how social defeat at different stages of adolescence affects behavioral and cognitive symptoms commonly associated with psychiatric disorders. After stress exposure, the rats were assessed for anxiety-like behavior in the elevated plus maze, social interaction, and cognitive flexibility through set-shifting and reversal-learning tasks under immediate and delayed reward conditions. The results showed that CSDS during EA, but not LA, led to impaired cognitive flexibility in adulthood, as evidenced by increased perseverative and regressive errors in the set-shifting and reversal-learning tasks, particularly under the delayed reward condition. This suggests that the timing of stress exposure during development has a significant impact on the long-term consequences for behavioral and cognitive function. The findings highlight the vulnerability of the prefrontal cortex, which undergoes critical maturation during early adolescence, to the effects of social stress. Overall, this study demonstrates that the timing of social stressors during adolescence can differentially shape the developmental trajectory of cognitive flexibility, with important implications for understanding the link between childhood/adolescent adversity and the emergence of psychiatric disorders.

RESUMO

The gut microbiota plays a key role in the brain function impairment caused by chronic stress, yet its exact mechanism remains unclear. Many studies have revealed the important role of miR-124 in the central nervous system. Meanwhile, previous studies have indicated that miR-124 may be regulated by chronic stress and gut microbiota. Here, we aimed to explore whether miR-124 serves as a mediator for the impacts of gut microbial dysbiosis on brain function in mice subjected to chronic stress. Repeated daily restraint stress for 4 weeks was used to induce chronic stress in mice. Chronic stress resulted in gut microbial dysbiosis, abnormal behaviors, and a decrease in hippocampal miR-124 levels. Treatment with different probiotic mixtures significantly alleviated the effects of chronic stress on hippocampal miR-124 levels and mouse behaviors. Suppression of hippocampal miR-124 expression reversed the beneficial effects of probiotics on cognitive function, neurogenesis, and related molecular markers in chronically stressed mice. Bioinformatics analysis and qPCR suggested that Ptpn11 might be a target gene for miR-124 in mediating the effects of gut microbial dysbiosis on brain function in these mice. These findings suggest that miR-124 is a pivotal regulator that mediates the detrimental effects of gut microbial dysbiosis on brain function and the subsequent cognitive impairment during chronic stress.

RESUMO

INTRODUCTION: Developed by the Global Vascular Guidelines committee, the Global Limb Anatomic Staging System (GLASS) is an angiographic scoring system used for quantifying infrainguinal disease extent and predicting treatment success with endovascular techniques (EVT). Currently, no other risk prediction model is available for patients with chronic limb threatening ischemia (CLTI) undergoing EVT. GLASS' validation and adoption outside academic institutions for research are limited. Thus, this longitudinal multicenter prospective study aims to examine GLASS' validity and reliability in predicting major acute limb events and overall survival (OS) in patients with CLTI undergoing EVT. METHODS AND ANALYSIS: This prospective, international, multicenter, observational study will include patients with CLTI undergoing EVT (PROMOTE-GLASS) (ClinicalTrials.gov; ID: NCT06186544) identified through routine clinical referrals and emergency visits to vascular units in participating centers. Only patients who are referred for EVT will be recruited. The primary outcomes are immediate technical success, immediate technical failure, and 1-year limb base patency. The secondary outcomes are major adverse limb events, major lower limb amputation, and OS in patients presenting with CLTI who undergo EVT up to 1 year after the procedure. Clinical and imaging data will be analyzed at the end of follow-up to validate risk prediction. This protocol outlines our approach for identifying cases, GLASS score calculation, outcome measures assessment, and a statistical analysis plan. ANTICIPATED IMPLICATIONS: PROMOTE-GLASS holds significant implications and can potentially revolutionize clinical decision-making by assisting clinicians in identifying patients who are likely to benefit from EVT. Ultimately, reduce the need for more invasive procedures and improve patient outcomes. Furthermore, PROMOTE-GLASS can provide useful information, including patient selection, for future randomized controlled trials (RCTs) investigating EVT for CLTI. PROMOTE-GLASS anticipated implications on the vascular community are rooted in its potential to improve patient care, inform future research, and address limitations in existing literature regarding CLTI treatment outcomes.

RESUMO

Cardiac myxomas are the most common primary benign tumors of the heart. The occlusion of peripheral arteries and complete obstruction of the abdominal aorta by a tumor embolus presents with distinct clinical manifestations. Herein, we present the case of a 38-year-old male with acute paresthesia, muscle weakness, erythematous, and violaceous changes in skin color localized to the dorsum of the left forefoot initially treated as cutaneous vasculitis. Further studies revealed the total occlusion of the terminal abdominal aorta by a saddle embolus from a cardiac myxoma. A multidisciplinary team consisting of cardiothoracic and vascular surgeons were involved in treating the patient, which resulted in full resolution of the case. This paper details the progression of acute bilateral limb ischemia to chronic limb threatening ischemia resulting from the total occlusion of the terminal abdominal aorta by a saddle embolus.

RESUMO

BACKGROUND: Increased blood-brain barrier (BBB) permeability is implicated in the pathophysiology of major depressive disorder (MDD). While aerobic exercise has shown promise in mitigating MDD symptoms by potentially preserving BBB integrity, the detailed mechanisms remain unclear. This study explores these mechanisms to assess aerobic exercise's therapeutic potential for MDD. METHODS: Male C57BL/6 J mice were used in this study to investigate the effects of aerobic exercise on CUS-induced BBB permeability and depressive-like behaviors. Chronic unpredictable stress (CUS)-induced MDD mouse models were divided into three groups: Control, CUS, and CUS+Exercise. We monitored body weight, blood S100ß levels, and cytokines via ELISA. Claudin-5 and Caveolin-1 (CAV-1) expressions in the medial prefrontal cortex were evaluated using Western blotting and immunofluorescence. BBB permeability was assessed using biocytin-TMR and Alb-Alexa 594 tracers. Transmission electron microscopy was used to observe ultrastructural changes in the BBB directly. Depression-related behaviors were tested through several behavioral assays. RESULTS: CUS significantly increased CAV-1 expression and Alb-Alexa 594 leakage, suggesting enhanced transcellular BBB permeability. Despite unchanged Claudin-5 levels, its tight junction ultrastructure was altered, leading to increased biocytin-TMR leakage. Aerobic exercise ameliorated these disruptions, reduced inflammatory cytokines, and improved behavioral outcomes in CUS mice. CONCLUSION: Disruptions in both paracellular and transcellular BBB pathways are pivotal in depression development. Aerobic exercise offers potential therapeutic benefits for MDD linked with BBB dysfunction by mitigating stress-induced structural and functional changes.

RESUMO

The quantification of submicroscopic minimal residual disease (MRD) after therapy proved to have independent prognostic significance in many mature B-cell malignancies. With the advent of routine benchtop cytometers capable of simultaneously analyzing ≥8 colors and with improved standardization, flow cytometry has become the method of choice for MRD assessments in some lymphoma entities. Herein we describe general aspects of flow cytometric standardization. Chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) are used as examples to explain the technical standardization of flow cytometry for MRD detection according to EuroFlow strategies. MRD data acquisition and detailed analysis in MM and CLL is a particular focus of this chapter.

RESUMO

Thorough examination of clonotypic B-cell receptor immunoglobulin (BcR IG) gene rearrangement sequences in patients with mature B-cell malignancies has revealed significant repertoire restrictions, leading to the identification of subsets of patients expressing highly similar, stereotyped BcR IG. This discovery strongly suggests selection by common epitopes or classes of structurally similar epitopes in the development of these tumors. Initially observed in chronic lymphocytic leukemia (CLL), where the stereotyped fraction accounts for a substantial fraction of patients, stereotyped BcR IGs have also been identified in other mature B-cell malignancies, including mantle cell lymphoma (MCL) and splenic marginal zone lymphoma (SMZL).Further comparisons across different entities have indicated that stereotyped IGs are predominantly "disease-biased," indicating distinct immune pathogenetic trajectories. Notably, accumulating evidence suggests that molecular subclassification of mature B-cell malignancies based on BcR IG stereotypy holds biological and clinical relevance. Particularly in CLL, patients belonging to the same subset due to the expression of a specific stereotyped BcR IG exhibit consistent biological backgrounds and clinical courses, especially for major and extensively studied subsets. Therefore, robust assignment to stereotyped subsets may aid in uncovering mechanisms underlying disease initiation and progression, as well as refining patient risk stratification. In this chapter, we offer an overview of recent studies on BcR IG stereotypy in mature B-cell malignancies and delineate past and present methodological approaches utilized for the identification of stereotyped BcR IG.

RESUMO

Minimal residual disease (MRD) diagnostics is of high clinical relevance in patients with indolent B-cell non-Hodgkin lymphomas (B-NHL), B-cell chronic lymphocytic leukemia (CLL), and multiple myeloma and serves as a surrogate parameter to evaluate treatment effectiveness and long-term prognosis. Real-time quantitative PCR (RQ-PCR) targeting circulating lymphoma cells is still the gold standard for MRD detection in indolent B-NHL and currently the most sensitive and the most broadly applied method in follicular lymphoma (FL) and mantle cell lymphoma (MCL). Alternatively, droplet digital PCR (ddPCR) can be used for MRD monitoring in multiple myeloma, mantle cell lymphoma, CLL, and FL with comparable sensitivity, accuracy, and reproducibility.The most broadly applicable MRD target in B-NHL is the junctional regions of the rearranged immunoglobulin heavy (IGH) and light chain genes. Complete and incomplete IGH and additionally IG kappa light chain rearrangements can be used as targets for MRD. Next-generation sequencing (NGS) of IG-rearrangements (IG-NGS) as new sequencing-based technology can overcome the limitation of PCR-based approaches and has a potential for higher sensitivity. Chromosomal translocations like the t(14;18)(q32;q21) translocation associated with IGH::BCL2 fusion in FL and t(11;14)(q13;q32) translocation in MCL leading to the IGH::CCND1 fusion can be used as MRD target in selected lymphoma subtypes. In patients with CLL, both flow-cytometry and RQ-PCR are equally suited for MRD assessment as long as a sensitivity of 10-4 is achieved.MRD diagnostics targeting the IG loci is complex and requires extensive knowledge and experience because the junctional regions of each clonal rearranged gene have to be identified before the patient-specific PCR assays can be designed for MRD monitoring. In addition, the presence and load of somatic hypermutation within the rearranged IGH gene occurring during B-cell development of germinal center and post-germinal center B-cell lymphomas may hamper appropriate primer binding leading to false-negative results. The translocations mentioned above have the advantage that consensus forward primers and probes, both placed in the breakpoint regions of chromosome 18 in FL and chromosome 11 in MCL, can be used in combination with a reverse primer placed in the IGH joining region of chromosome 14. PCR-based methods using allele-specific primers can reach a high sensitivity of up to 10-5. This chapter provides all relevant background information and technical aspects for the complete laboratory process from detection of the clonal IG gene rearrangements and the chromosomal translocations at diagnosis to the actual MRD measurements in clinical follow-up samples of B-NHL. However, it should be noted that MRD diagnostics for clinical treatment protocols has to be accompanied by regular international quality control rounds to ensure the reproducibility and reliability of the MRD results. This is available by the EuroMRD network ( https://euromrd.org ), a subgroup of ESHLO ( https://eslho.org ).

RESUMO

Resumen Objetivo: El objetivo de esta revisión sistemática con metaanálisis es sintetizar la evidencia científica disponible sobre los efectos de la terapia manual aplicada de forma aislada en comparación a otras intervenciones en el dolor, la capacidad funcional, la impresión global de mejoría y severidad de síntomas autopercibida en personas con fibromialgia. Metodología: Se realizó una revisión sistemática y metaanálisis con búsqueda electrónica en MEDLINE, WoS, SCOPUS, PEDro, CENTRAL y LILACS. Resultados: Once estudios cumplieron con los criterios de selección y seis fueron incluidos en una síntesis cuantitativa. El dolor al terminar el tratamiento tuvo una diferencia de medias de -0.42 (IC al 95% -1.14, 0.30, p = 0.25), el estado funcional al terminar el tratamiento tuvo una diferencia de medias de -0.15 (IC al 95% -0.69, 0.40, p = 0.60), la impresión global de salud al terminar el tratamiento tuvo una diferencia de media de -1.13 (IC al 95% -1.68, -0.57 p = <0.00) y posterior a doce meses una diferencia de media de -0.48 (IC al 95% -0.78, -0.19 p = <0.00), la impresión global de severidad después de la intervención tuvo una diferencia de medias de -0.62 (IC al 95% -1.22, -0.03, p = 0.04) y posterior a doce meses una diferencia de medias de -0.43 (IC al 95% -1.18, 0.32, p = 0.26). Conclusiones: La terapia manual aislada es una intervención que podría mejorar significativamente la autopercepción del estado global de mejoría y severidad de síntomas a corto plazo en comparación a agentes físicos placebo. Sin embargo, no es mejor que otras intervenciones para disminuir el dolor y mejorar la capacidad funcional.


Abstract Objective: The aim of this systematic review with meta-analysis is to synthesize the available scientific evidence on the effects of manual therapy applied in isolation in comparison to other interventions on pain, functional capacity, global impression of improvement, and self-perceived severity of symptoms in people with fibromyalgia. Methodology: A systematic review with meta-analysis was conducted with electronic search of MEDLINE, WoS, SCOPUS, PEDro, CENTRAL, and LILACS. Results: Eleven studies met the selection criteria and six were included in a quantitative synthesis. Pain at the end of treatment had a mean difference of -0.42 (95% CI -1.14, 0.30, p = 0.25), functional status at the end of treatment had a mean difference of -0.15 (95% CI - 0.69, 0.40, p = 0.60), the global impression of health at the end of treatment had a mean difference of -1.13 (95% CI -1.68, -0.57 p = <0.00) and a mean difference of -0.48 after twelve months (95% CI -0.78, -0.19 p = <0.00), the global impression of severity after the intervention had a mean difference of -0.62 (95% CI -1.22, -0.03, p = 0.04 ) and a mean difference of -0.43 after twelve months (95% CI -1.18, 0.32, p = 0.26). Conclusions: Isolated manual therapy is an intervention that could significantly improve the self-perception of the global state of improvement and severity of symptoms in the short term compared to sham physical agents. However, it is not better than other interventions to reduce pain and improve functional capacity.

El modelo multivariado indicó que ser mujer está asociado a la progresión de la enfermedad renal cuando se ajusta por TFG (OR 1,07 (IC 1,03-1,12; p = <0,001)), la edad (OR 1,07 (IC 1,03-1,11; p = <0,001)), creatinina (OR 25,2 (IC 5,10-125,1); p = <0,001)) y albuminuria (OR 1,00 (IC 0,99 - 1,01); p= <0,001)). Conclusión: se hace necesario en un futuro estudio involucrar variables de adherencia al tratamiento, así como el tiempo de evolución de la patología y algunos elementos como hábitos, estilos de vida y calidad del control.


Abstract Introduction : Chronic kidney disease (CKD) is considered in public health as a serious problem, given its behavior and lethal potential, this is defined as irreversible changes in kidney function or its structure that last at least 3 months. Objective : To determine the risk factors associated with the progression of CKD in patients treated at the Hospital San Juan de Dios in the municipality of Pamplona Norte de Santander for the period 2019 - 2021. Methodology : Cross-sectional, analytical, retrospective study. Sociodemographic and clinical characteristics were studied and analyzed using descriptive and inferential statistical methods, a multivariate logistic regression model was constructed with a significance level of 0.05. Results : The prevalence of stage 3a chronic kidney disease (CKD) was 74.9%. Out of the total patients included in the research, 186 (53.7%) showed evidence of progression. The multivariate model indicated that being female is associated with the progression of renal disease when adjusted for glomerular filtration rate (GFR) (OR 1.07 (IC 1.03-1.12; p < 0.001)), age (OR 1.07 (IC 1.03-1.11; p < 0.001)), creatinine (OR 25.2 (IC 5.1-125.1); p < 0.001)), and albuminuria (OR 1.00 (IC 0.99-1.01); p < 0.001)). Conclusions: It is necessary in a future study to involve variables of adherence to treatment and treatment, as well as the time of evolution of the pathology and some elements such as habit, lifestyles and quality of control.

RESUMO

Adrenergic receptors (ARs) are preferentially expressed by innate lymphocytes such as natural killer (NK) cells. Here, we study the effect of epinephrine-mediated stimulation of the ß2-adrenergic receptor (ß2AR) on the function of human NK cells. Epinephrine stimulation inhibited early NK cell signaling events and blocked the function of the integrin LFA-1. This reduced the adhesion of NK cells to ICAM-1, explaining how NK cells are mobilized into the peripheral blood upon epinephrine release during acute stress or exercise. Additionally, epinephrine stimulation transiently reduced NK cell degranulation, serial killing, and cytokine production and affected metabolic changes upon NK cell activation via the cAMP-protein kinase A (PKA) pathway. Repeated exposure to ß2AR agonists resulted in the desensitization of the ß2AR via a PKA feedback loop-initiated G-protein switch. Therefore, acute epinephrine stimulation of chronically ß2AR stimulated NK cells no longer resulted in inhibited signaling and reduced LFA-1 activity. Sustained stimulation by long-acting ß2-agonists (LABA) not only inhibited NK cell functions but also resulted in desensitization of the ß2AR. However, peripheral NK cells from LABA-treated asthma patients still reacted unchanged to epinephrine stimulation, demonstrating that local LABA administration does not result in detectable systemic effects on NK cells.

RESUMO

BACKGROUND: The escalating global burden of stress and depression underscores an urgent need to unravel their complex interrelationships and underlying mechanisms. This investigation delves into the intricate dynamics between stress and depression, spotlighting the Neuroimmunoinflammatory Stress Model (NIIS), which elucidates the pivotal role of cellular and molecular pathways in mediating these conditions. METHODS: Through an exhaustive review of literature spanning epidemiology, neurobiology, and psychoneuroimmunology, this study synthesizes the current understanding of stress and depression. It accentuates the definitional scopes, interplay, and intricacies of the NIIS model, which integrates neuroimmune-inflammatory responses into the conceptual framework of the stress-depression interaction. RESULTS: By identifying stress as a multifactorial reaction to perceived adversities and depression as a manifestation of prolonged stress exposure, our analysis foregrounds the NIIS model. This paradigmatic model reveals the transition from normal stress responses to pathological neuroinflammatory pathways, highlighting neurotransmitter imbalances, disruptions in neuronal and glial homeostasis, and ensuing low-grade neuroinflammation as key factors in the pathogenesis of depression under chronic stress conditions. The NIIS model identifies prolonged cellular pro-inflammatory stress of neurons and microglia as a fundamental pathological subsystem of many neuropsychiatric disorders. In turn, neuroinflammation and associated neurodegenerative processes are complications of chronic psychoemotional stress, which can clinically manifest as depression. CONCLUSIONS: The NIIS model views depression as the terminal stage of chronic stress, pathogenetically linked to latent neuroinflammation. This insight not only advances our understanding of their etiopathogenesis but also paves the way for developing precise therapeutic interventions.

RESUMO

Chronic pelvic pain is a debilitating complex condition affecting men and women, but the knowledge gaps are salient. The condition impacts somatic, sexual, and mental health, as well as social, family, and work life. The complexity of the condition demands for a giant step away from traditional dualistic clinical approach. This commentary underpins the need to interweave multidisciplinary research within a biopsychosocial framework, as well as enhanced inclusion of the user perspective.

RESUMO

INTRODUCTION: Wheelchair training is pivotal for safety, independence, and occupational engagement in the community, yet adults coming into wheelchair use often receive insufficient or untailored training. This research aimed to understand the range and type of manual wheelchair training approaches that exist for adults commencing wheelchair use. METHOD: A systematic scoping review involved searching eight electronic databases and grey literature up to September 2023. Papers relating to manual wheelchair training for adults and their caregivers were included for data extraction. Eighty-seven articles were included in this review. The International Classification of Functioning (ICF) was used to organise and analyse data related to intended training outcomes. CONSUMER AND COMMUNITY INVOLVEMENT: Consumer consultation was not included in this review; however, the outcomes suggest that involving consumers in future wheelchair training research is critical to assure community participation outcomes. RESULTS: Data were extracted from 87 papers. Manual wheelchair training was delivered across diverse contexts encompassing varied support structures, trainer backgrounds, and technology and was commonly directed towards wheelchair users with spinal cord injury. Intended training outcomes most frequently mapped to the activity and participation component of the ICF (n = 39), followed by personal factors (n = 27), body structures and functions (n = 18), and environmental factors (n = 3), with limited focus on longer term occupational engagement outcomes. CONCLUSION: Most existing manual wheelchair training focussed on the acquisition of individual wheelchair skill and may not facilitate generalised and long-term occupational participation outcomes. Further exploration into the contexts that support occupational engagement, particularly for older adults with progressive conditions, is required to support service provision. PLAIN LANGUAGE SUMMARY: We looked at what manual wheelchair training approaches exist for adults who need to use a manual wheelchair and what training helps people to do/achieve. We did a scoping review that looked at literature about manual wheelchair training programs for adult wheelchair users. We found 87 research papers and training programs that we included in our review. We recorded and analysed information from all the papers about the wheelchair training programs and outcomes for people who do these programs. We found that manual wheelchair training can be done in structured or ad hoc ways, can have different amounts of training, can be provided face-to-face or online, and can be given by different allied health professionals and other wheelchair users. Most training programs had short-term outcomes like learning manual wheelchair skills, being able to use the wheelchair properly, and feeling confident about using a wheelchair. Some had longer term outcomes about being able to use the manual wheelchair in everyday activities. Most people who did the training programs that we looked at in this review were manual wheelchair users with spinal cord injury. Because not many wheelchair programs have been tried with people who do not have a spinal cord injury, it is hard for occupational therapists to make recommendations about training for other people who use a manual wheelchair. Manual wheelchair training that is done in the community and made to meet the needs of individuals may help people with using their wheelchair for their everyday activities and participate in their community.
