RESUMO
There is mounting evidence of the value of clinical genome sequencing (cGS) in individuals with suspected rare genetic disease (RGD), but cGS performance and impact on clinical care in a diverse population drawn from both high-income countries (HICs) and low- and middle-income countries (LMICs) has not been investigated. The iHope program, a philanthropic cGS initiative, established a network of 24 clinical sites in eight countries through which it provided cGS to individuals with signs or symptoms of an RGD and constrained access to molecular testing. A total of 1,004 individuals (median age, 6.5 years; 53.5% male) with diverse ancestral backgrounds (51.8% non-majority European) were assessed from June 2016 to September 2021. The diagnostic yield of cGS was 41.4% (416/1,004), with individuals from LMIC sites 1.7 times more likely to receive a positive test result compared to HIC sites (LMIC 56.5% [195/345] vs. HIC 33.5% [221/659], OR 2.6, 95% CI 1.9-3.4, p < 0.0001). A change in diagnostic evaluation occurred in 76.9% (514/668) of individuals. Change of management, inclusive of specialty referrals, imaging and testing, therapeutic interventions, and palliative care, was reported in 41.4% (285/694) of individuals, which increased to 69.2% (480/694) when genetic counseling and avoidance of additional testing were also included. Individuals from LMIC sites were as likely as their HIC counterparts to experience a change in diagnostic evaluation (OR 6.1, 95% CI 1.1-∞, p = 0.05) and change of management (OR 0.9, 95% CI 0.5-1.3, p = 0.49). Increased access to genomic testing may support diagnostic equity and the reduction of global health care disparities.

Locally advanced cutaneous squamous cell carcinoma can erode into blood vessels, leading to vascular blowout, requiring emergent surgical intervention. We describe a first case of this disease complication which was effectively managed with endovascular stenting as a bridge to effective systemic and regional therapy. We discuss the efficacy of this staged approach which is novel and timely in a clinical environment of increasingly effective systemic therapies.

INTRODUCTION: Objective measurements for applicant ranking are becoming increasingly important, not only to help address the growing number of general surgery applicants each year but also to minimize bias and ensure consistency. We assessed if our general surgery applicant scoring system was an effective tool for accurately predicting the results of the resident match. METHODS: A retrospective review of applicant rank lists from 2017 to 2020 was conducted. Applicants were ranked based on the sum of preinterview and interview scores. The preinterview score is an objective metric related to the applicant's academic portfolio. The interview score is a standardized score based on interview performance. We reviewed match results from ranked candidates and categorized them as academic categorical (AC), community categorical (CC), preliminary surgical (PS), nonsurgical specialty (NS), or unmatched (UM) positions. RESULTS: A total of 378 applicants were interviewed. Forty-nine percent matched into AC, 22% into CC, 11% into PS, and 5% into NS positions, while 13% of the interviewees were UM. Applicants who matched into AC positions had significantly higher preinterview and interview scores than applicants in other categories. Applicants who matched into CC positions had significantly higher interview scores than those categorized as UM, but their preinterview scores did not differ significantly from the UM group. Applicants who did not match into a categorical position (PS, NS, or UM) did not have significantly different preinterview or interview scores from one another. CONCLUSIONS: Our standardized scoring system was effective in stratifying which applicants would match into categorical general surgery residency programs.

A better understanding of molecular events following cartilage injury is required to develop treatments that prevent or delay the onset of trauma-induced osteoarthritis. In this study, alterations to SIRT1 activity in bovine articular cartilage explants were evaluated in the 24 h following a mechanical overload, and the effect of pharmacological SIRT1 activator SRT1720 on acute chondrocyte injury was assessed. SIRT1 enzymatic activity decreased as early as 5 min following the mechanical overload, and remained suppressed for at least 24 h. The chondrocyte injury response, including apoptosis, oxidative stress, secretion of inflammatory mediators, and alterations in cartilage matrix expression, was prevented with pharmacological activation of SIRT1 in a dose-dependent manner. Overall, the results implicate SIRT1 deactivation as a key molecular event in chondrocyte injury following a mechanical impact overload. As decreased SIRT1 signaling is associated with advanced age, these findings suggest that downregulated SIRT1 activity may be common to both age-related and injury-induced osteoarthritis.

INTRODUCTION: Over the last decade, there has been a 32% decrease in independent plastic surgery fellowships. The growing prevalence of 6-year integrated plastic surgery residencies, duty hour restrictions, and new subspecialty training fellowships for general surgeons have changed the training experience of plastic surgery fellows. METHODS: A retrospective review of the Accreditation Council for Graduate Medical Education (ACGME) case logs for graduating fellows of independent plastic surgery fellowships in the United States was conducted from 2011 to 2019. A linear regression analysis was conducted for each case log code and category, and a 95% level of confidence was assumed (α = 0.05). RESULTS: In 2011, 141 residents from 69 programs graduated with an average of 1469.7 cases. In 2019, 84 residents from 47 programs graduated with an average of 1952 cases. Index procedures significantly increased overall during the 9 y (P < 0.001). Categorical cases increased in esthetics (P < 0.001), including facelift, browlift, blepharoplasty, and more. Categorical cases increased in reconstructive surgery (P < 0.001), including treatment of deformities of the skin, lower extremities, and trunk, nerve decompression, and hand reconstruction. In breast procedures, an increase was seen in the reduction of mammoplasty, reconstruction, and treatment of other breast deformities. In head and neck procedures, an increase was seen in resection of head and neck neoplasms and secondary cleft lip repair. Decreases in procedural numbers were seen in primary cleft lip repair and hand reconstruction by primary closure. CONCLUSIONS: Despite a 32% decline in the number of independent plastic surgery fellowships over the last 9 y, plastic surgery fellows are obtaining significantly more surgical experience, both in esthetic and reconstructive surgery.

BACKGROUND: General Surgery residencies use protected education time in various fashions in order to optimize content quality and yield for their learners. This knowledge is tested annually with the American Board for Surgery In-Training Examination (ABSITE) exam and is used to evaluate several aspects of a resident. We hypothesized that using a jeopardy game in educational conference would encourage residents to engage in self-learning and improve ABSITE scores at a single institution. MATERIALS AND METHODS: At a single institution, during protected education conference, residents played an hour-long surgical jeopardy game every 7 wk to summarize high yield topics discussed during the previous 6 wk of didactic learning. A 5-point Likert survey was completed by general surgery residents to discern the utility of the game format for learning. The ABSITE category scores were also evaluated from the year before and the year after the game was implemented. RESULTS: Twenty-four general surgery residents took the survey with >80% agreeing that the jeopardy format was either a fun or an effective way to learn general surgery topics. Additionally, over 80% of residents thought the game format helped with retention of knowledge. ABSITE categories that had a jeopardy session improved from 65.9% to 70.4% correct (P = 0.0003). ABSITE categories that did not have dedicated jeopardy had a non-significant increase in scores (67.7%-69.9%, P = 0.1). CONCLUSIONS: Implementing surgical jeopardy as a component of educational conferences in general surgery resident training is correlated with improvement of ABSITE scores. Surgical jeopardy may be easily adopted and implemented to stimulate self-directed learning for residents.

BACKGROUND: Two restrictive factors for surgical training through simulation, are the cost of and accessibility to materials and consoles for simulation models. Commercial surgical simulation models continue to maintain high prices with a wide range of fidelity levels. We believe that by utilizing in-house fabrication, these barriers can be decreased while maintaining and even improving the functionality of surgical simulation models as well as increase their individualization and customization. METHODS: By using a combination of digital and manual fabrication techniques such as 3D printing and basic mold making methods, we were able to create models equivalent to current commercial products by utilizing the first of its kind MakerHEALTH space and collaborating with our surgical simulation staff. We then compared our research and development, start-up, materials, operational, and labor costs to buying comparable commercial models with the simulation usage rates of our institution. RESULTS: We were able to decrease the costs of a 6 model simulation sample set (appendectomy, cholecystectomy, common bile duct exploration, ventral hernia, chest tube insertion, and suture pads) at our institution from $99,646.60 to $13,817.21 for a medical student laborer, $14,500.56 for a surgical resident laborer, $15,321.08 for a simulation staff laborer, and $18,984.48 for an attending physician laborer. CONCLUSION: We describe successful approaches for the creation of cost-effective and modular simulation models with the aim of decreasing the barriers to entry and improving surgical training and skills. These techniques make it financially feasible for learners to train during larger faculty-led workshops and on an individual basis, allowing for access to simulation at any time or place.

Gastroesophageal junction (GEJ) cancer remains a clinically significant disease in Western countries due to its increasing incidence, which mirrors that of esophageal cancer, and poor prognosis. To develop novel and effective approaches for prevention, early detection, and treatment of patients with GEJ cancer, a better understanding of the mechanisms driving pathogenesis and malignant progression of this disease is required. These efforts have been limited by the small number of available cell lines and appropriate preclinical animal models for in vitro and in vivo studies. We have established and characterized a novel GEJ cancer cell line, GEAMP, derived from the malignant pleural effusion of a previously treated GEJ cancer patient. Comprehensive genetic analyses confirmed a clonal relationship between GEAMP cells and the primary tumor. Targeted next-generation sequencing identified 56 nonsynonymous alterations in 51 genes including TP53 and APC, which are commonly altered in GEJ cancer. In addition, multiple copy-number alterations were found including EGFR and K-RAS gene amplifications and loss of CDKN2A and CDKN2B. Histological examination of subcutaneous flank xenografts in nude and NOD-SCID mice showed a carcinoma with mixed squamous and glandular differentiation, suggesting GEAMP cells contain a subpopulation with multipotent potential. Finally, pharmacologic inhibition of the EGFR signaling pathway led to downregulation of key downstream kinases and inhibition of cell proliferation in vitro. Thus, GEAMP represents a valuable addition to the limited number of bona fide GEJ cancer cell lines.

BACKGROUND: Multiple adjuvant therapies for melanoma have been approved since 2015 based on randomized trials demonstrating improvements in recurrence-free survival (RFS) with adjuvant therapy after surgical resection of high-risk disease. Inclusion criteria for these trials required performance of a completion lymph node dissection (CLND) for positive sentinel lymph node (pSLN) disease. OBJECTIVE: We aimed to describe current practice for adjuvant therapies in patients with pSLN without CLND (active surveillance [AS]), and to evaluate recurrence in these patients. METHODS: Melanoma patients with pSLN between 2016 and 2019 were identified at two institutions. Demographic information, disease and treatment characteristics, and recurrence details were reviewed retrospectively. Patients were stratified by recurrence and patient-, treatment- and tumor-related characteristics were compared using Fisher's exact test and t test for categorical and continuous variables, respectively. RESULTS: Overall, 245 SLN biopsies were performed, of which 36 (14.7%) were pSLN. Of 36 pSLN, 4 underwent CLND and 32 underwent AS, of whom 22 (68.8%) received adjuvant therapy with the anti-programmed death-1 (PD1) inhibitor nivolumab (16/22), anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitor ipilimumab (3/22), or BRAF/MEK inhibitors (3/22). At a median follow up of 13.3 months, 7/32 (21.9%) patients on AS recurred, including 4/22 (18.2%) who received adjuvant therapy and 3/10 (30.0%) who did not. Tumor ulceration was significantly associated with recurrence. While not significant, acral lentiginous subtype appeared more common among those with recurrence. CONCLUSION: The majority (68.8%) of patients with pSLN managed without CLND were treated with adjuvant therapy. The 1-year RFS for patients managed with adjuvant therapy without CLND was 82%, which is similar to modern adjuvant therapy trials requiring CLND.

BACKGROUND: In a survey of students at our institution, suturing was the most desired workshop for simulation; however, cost, quality, and availability of skin pads is often prohibitive for suturing workshops. In-hospital fabrication may be utilized to manufacture noncommercial, high-fidelity, and low-cost simulation models. We describe the production, value, and face validation of our simulated skin model. MATERIALS AND METHODS: Using an in-hospital fabrication laboratory, we have developed a model for skin and subcutaneous tissue. Our model uses a variety of commercially available materials to simulate the epidermis, dermis, subcutaneous fat, fascia, and muscle. A cost analysis was performed by comparing it with other commonly used commercial skin models. Expert surgeons assessed the material characteristics, durability, and overall quality of our model in comparison with other commercial models. RESULTS: The materials cost of our novel skin pad model was 30.9% of the mean cost of five different commonly used foam and silicone-based commercial skin models. This low-cost model is more durable than the commercial models, does not require skin pad holders, and is of higher fidelity than the commercial products. In addition to skin closure, our model may be used to simulate fascial closure or fasciotomy. CONCLUSIONS: Model creation using in-hospital workspaces is an effective strategy to decrease cost while improving quality of surgical simulation. Our methods for creation of an inexpensive and high-fidelity skin pad may be purposed for several soft tissue models.

Single multiplexed assays could replace the standard 2-tiered (STT) algorithm recommended for the laboratory diagnosis of Lyme disease if they perform with a specificity and a sensitivity superior or equal to those of the STT algorithm. We used human serum rigorously characterized to be sera from patients with acute- and convalescent-phase early Lyme disease, Lyme arthritis, and posttreatment Lyme disease syndrome, as well as the necessary controls (n = 241 samples), to select the best of 12 Borrelia burgdorferi proteins to improve our microfluidic assay (mChip-Ld). We then evaluated its serodiagnostic performance in comparison to that of a first-tier enzyme immunoassay and the STT algorithm. We observed that more antigens became positive as Lyme disease progressed from early to late stages. We selected three antigens (3Ag) to include in the mChip-Ld: VlsE and a proprietary synthetic 33-mer peptide (PepVF) to capture sensitivity in all disease stages and OspC for early Lyme disease. With the specificity set at 95%, the sensitivity of the mChip-Ld with 3Ag ranged from 80% (95% confidence interval [CI], 56% to 94%) and 85% (95% CI, 74% to 96%) for two panels of serum from patients with early Lyme disease and was 100% (95% CI, 83% to 100%) for serum from patients with Lyme arthritis; the STT algorithm detected early Lyme disease in the same two panels of serum from patients with early Lyme disease with a sensitivity of 48.5% and 75% and Lyme arthritis in serum from patients with Lyme arthritis with a sensitivity of 100%, and the specificity was 97.5% to 100%. The mChip-Ld platform outperformed the STT algorithm according to sensitivity. These results open the door for the development of a single, rapid, multiplexed diagnostic test for point-of-care use that can be designed to identify the Lyme disease stage.

INTRODUCTION: The optimal methodology for assessing comorbidity to predict various surgical outcomes such as mortality, readmissions, complications, and failure to rescue (FTR) using claims data has not been established. OBJECTIVE: Compare diagnosis-based and prescription-based comorbidity scores for predicting surgical outcomes. METHODS: We used 100% Texas Medicare data (2006-2011) and included patients undergoing coronary artery bypass grafting, pulmonary lobectomy, endovascular repair of abdominal aortic aneurysm, open repair of abdominal aortic aneurysm, colectomy, and hip replacement (N=39,616). The ability of diagnosis-based [Charlson comorbidity score, Elixhauser comorbidity score, Combined Comorbidity Score, Centers for Medicare and Medicaid Services-Hierarchical Condition Categories (CMS-HCC)] versus prescription-based Chronic disease score in predicting 30-day mortality, 1-year mortality, 30-day readmission, complications, and FTR were compared using c-statistics (c) and integrated discrimination improvement (IDI). RESULTS: The overall 30-day mortality was 5.8%, 1-year mortality was 17.7%, 30-day readmission was 14.1%, complication rate was 39.7%, and FTR was 14.5%. CMS-HCC performed the best in predicting surgical outcomes (30-d mortality, c=0.797, IDI=4.59%; 1-y mortality, c=0.798, IDI=9.60%; 30-d readmission, c=0.630, IDI=1.27%; complications, c=0.766, IDI=9.37%; FTR, c=0.811, IDI=5.24%) followed by Elixhauser comorbidity index/disease categories (30-d mortality, c=0.750, IDI=2.37%; 1-y mortality, c=0.755, IDI=5.82%; 30-d readmission, c=0.629, IDI=1.43%; complications, c=0.730, IDI=3.99%; FTR, c=0.749, IDI=2.17%). Addition of prescription-based scores to diagnosis-based scores did not improve performance. CONCLUSIONS: The CMS-HCC had superior performance in predicting surgical outcomes. Prescription-based scores, alone or in addition to diagnosis-based scores, were not better than any diagnosis-based scoring system.

BACKGROUND: For patients presenting with symptomatic cholelithiasis, cholecystectomy is the definitive treatment modality. Our goal was to evaluate the surgical follow-up and outcomes in patients seen in the emergency department (ED) for an episode of symptomatic cholelithiasis and discharged home for elective follow-up. METHODS: We performed a retrospective review of consecutive patients seen in the ED for cholelithiasis and discharged without hospital admission between August 2009 and May 2014. All patients were followed for 2 y from the date of the initial ED visit. We evaluated outpatient surgeon visits, elective and emergent cholecystectomy rates, and additional ED visits. Cumulative incidence and Kaplan-Meier curves were used to examine the time from the initial ED visit to outpatient surgeon evaluation and the time from the initial ED visit to ED readmission. RESULTS: Seventy-one patients were discharged from the ED with a diagnosis of symptomatic gallstones. Patients who had an elective cholecystectomy in the 2 y after the initial visit were 12.6%. In this group, the mean time from the initial ED visit to outpatient surgeon follow-up was 7.7 d, and all elective cholecystectomies occurred within 1 mo of the initial visit. Of the 62 patients who did not have an elective cholecystectomy, only 14.5% of patients in this group had outpatient surgeon follow-up at mean time of 137 d from the initial ED visit for symptomatic gallstones. In addition, 37.1% of patients in this group had additional ED visits for gallstone-related symptoms, with 17.7% of patients having two or more additional ED visits, and 12.9% required emergent and/or urgent cholecystectomy. Additional ED visits (43.5%) occurred within 1 mo and 60.9% within 3 mo of their initial ED visit. In patients with additional ED visits for symptomatic cholelithiasis, 60.9% had more than one abdominal ultrasound or computed tomography scan during the course of multiple visits. CONCLUSIONS: Failure to achieve a timely surgical follow-up leads to multiple ED readmissions and emergent gallstone-related hospitalizations, including emergency cholecystectomy. System-level interventions to ensure outpatient surgical follow-up within 1-2 wk of the initial ED visit has the potential to improve outcomes for patients with symptomatic biliary colic.

This commentary highlights the importance of social and nature prescribing programs reflecting culturally diverse perspectives and practices. Creating and holding space for Indigenous and other worldviews should be a key priority of nature prescribing, a relatively recent practice in Canada that recognizes and promotes health benefits associated with engaging in a variety of activities in natural settings. Central to designing and delivering nature prescribing that is culturally inclusive and grounded in fulfilling obligations of reconciliation is recognizing the ongoing dominance of Western worldviews and their associated implications for decolonizing and Indigenizing nature-based programming. Consciously working to expand Western values, with the aim of extending nature prescribing practices beyond mere nature exposure to fostering emotional connections to nature, is a critically important part of the ongoing development of nature-based interventions and nature prescribing.
Nature prescribing is an increasingly recognized aspect of social prescribing that acknowledges and promotes enhanced health benefits associated with natural settings to address illness and promote health and wellness. The Western worldview maintains a narrow view of human relations with nature, consisting of humancentric needs and interests. The limited priority that the Western worldview places on the relationship with nature and the importance of establishing and maintaining nature connection, may limit the potential reach and benefits of nature prescribing. Nature prescribing efforts should recognize pre-existing, nature-based approaches such as land-based healing practised by Indigenous people and ensure culturally inclusive design and practices.
La prescription d'exposition à la nature, une dimension de plus en plus reconnue de la prescription sociale, reconnaît et promeut les bienfaits de l'environnement naturel pour la santé, le bien-être et le traitement des maladies. Le monde occidental entretient une vision étroite des relations entre la nature et l'être humain, qui se résume aux besoins et aux intérêts de ce dernier. La priorité limitée accordée dans le monde occidental à la relation avec la nature et à l'importance des liens avec la nature risque de limiter la portée et les avantages des prescriptions d'exposition à la nature. Les efforts en matière de prescription d'exposition à la nature devraient tenir compte des approches antérieures fondées sur la nature, comme la guérison par la terre pratiquée par les Autochtones, et assurer l'inclusivité culturelle sur le plan de la conception et des pratiques.

Importance: Individuals who are incarcerated represent a vulnerable group due to concerns about their ability to provide voluntary and informed consent, and there are considerable legal protections regarding their participation in medical research. Little is known about the quality of surgical care received by this population. Objective: To evaluate perioperative surgical care provided to patients who are incarcerated within the Texas Department of Criminal Justice (TDCJ) and compare their outcomes with that of the general nonincarcerated population. Design, Setting, and Participants: This cohort study analyzed data from patients who were incarcerated within the TDCJ and underwent general or vascular surgery at the University of Texas Medical Branch (UTMB) from 2012 to 2021. Case-specific outcomes for a subset of these patients and for patients in the general academic medical center population were obtained from the American College of Surgeons National Quality Improvement Program (ACS-NSQIP) and compared. Additional quality metrics (mortality index, length of stay index, and excess hospital days) from the Vizient Clinical Data Base were analyzed for patients in the incarcerated and nonincarcerated groups who underwent surgery at UTMB in 2020 and 2021 to provide additional recent data. Patient-specific demographics, including age, sex, and comorbidities were not available for analysis within this data set. Main Outcome and Measures: Perioperative outcomes (30-day morbidity, mortality, and readmission rates) were compared between the incarcerated and nonincarcerated groups using the Fisher exact test. Results: The sample included data from 6675 patients who were incarcerated and underwent general or vascular surgery at UTMB from 2012 to 2021. The ACS-NSQIP included data (2012-2021) for 2304 patients who were incarcerated and 602 patients who were not and showed that outcomes were comparable between the TDCJ population and that of the general population treated at the academic medical center with regard to 30-day readmission (6.60% vs 5.65%) and mortality (0.91% vs 1.16%). However, 30-day morbidity was significantly higher in the TDCJ population (8.25% vs 5.48%, P = .01). The 2020 and 2021 data from the Vizient Clinical Data Base included 629 patients who were incarcerated and 2614 who were not and showed that the incarcerated and nonincarcerated populations did not differ with regard to 30-day readmission (12.52% vs 11.30%) or morbidity (1.91% vs 2.60%). Although the unadjusted mortality rate was significantly lower in the TDCJ population (1.27% vs 2.68%, P = .04), mortality indexes, which account for case mix index, were similar between the 2 populations (1.17 vs 1.12). Conclusions and Relevance: Findings of this cohort study suggest that patients who are incarcerated have equivalent rates of mortality and readmission compared with a general academic medical center population. Future studies that focus on elucidating the potential factors associated with perioperative morbidity and exploring long-term surgical outcomes in the incarcerated population are warranted.

Ureteral defects can be repaired using a variety of different techniques that depend on the length and position of the defect. Here we describe a case where a long, upper-ureteral defect was successfully reconstructed using an appendiceal interposition graft. A 60-year-old female patient underwent resection of a right-sided retroperitoneal leiomyosarcoma that was encasing the entire upper ureter and obstructing the right kidney. The mass was resected en bloc, leaving behind an 11 cm ureteral defect. The defect was successfully reconstructed with an appendiceal interposition graft. Appendiceal interposition grafts are a feasible and effective approach for ureteral reconstruction in adults following oncologic resection. We describe various technical aspects that optimize the success of ureteral reconstruction.

RESUMO
Mesenchymal stem/stromal cells (MSCs) are multipotent somatic cells that have been widely explored in the field of regenerative medicine. MSCs possess the ability to secrete soluble factors as well as lipid bound extracellular vesicles (EVs). MSCs have gained increased interest and attention as a result of their therapeutic properties, which are thought to be attributed to their secretome. However, while the use of MSCs as whole cells pose heterogeneity concerns and survival issues post-transplantation, such limitations are absent in cell-free EV-based treatments. EVs derived from MSCs are promising therapeutic agents for a range of clinical conditions and disorders owing to their immunomodulatory, pro-regenerative, anti-inflammatory, and antifibrotic activity. Recent successes with preclinical studies using EVs for repair and regeneration of damaged tissues such as cardiac tissue, lung, liver, pancreas, bone, skin, cornea, and blood diseases are discussed in this review. We also discuss delivery strategies of EVs using biomaterials as delivery vehicles through systemic or local administration. Despite its effectiveness in preclinical investigations, the application of MSC-EV in clinical settings will necessitate careful consideration surrounding issues such as: i) scalability and isolation, ii) biodistribution, iii) targeting specific tissues, iv) quantification and characterization, and v) safety and efficacy of dosage. The future of EVs in regenerative medicine is promising yet still needs further investigation on enhancing the efficacy, scalability, and potency for clinical applications.

Background. Individuals or persons who live with a disability (PWD) can experience unique financial occupation challenges. Financial education programs can address some challenges. Purpose. The aim of this study was to describe and critically appraise current financial education programs for PWD in Canada. Method. This environmental scan framed by scoping review methods included a critical appraisal of Canadian programs' online content and provider consultations. Researchers used four search methods to identify programs, interviewed service providers from four Canadian programs, and thematically analyzed interview transcripts. Findings. Researchers identified 134 programs; 50 (37.3%) included services. The online content of only 26 (19%) programs explicitly addressed accessibility; 106 (79%) programs' content was at least college reading level. The qualitative results include three themes: (a) individualized approach, (b) "getting the word out", and (c) service growth. Implications. There are financial education programs specific to PWD in Canada. Accessibility, individualization, advocacy, and development are needed.
