RESUMEN

Although the popularity of fish pedicures as cosmetic or routine services and/or tourist attractions has peaked in the past decade, the practice is still trending today and accompanying risks are less well-known by the public. More recently, a case of onychomadesis following fish pedicure has gained interest in both public and dermatologic populations, highlighting the importance of patient education. In this study, we aimed to demonstrate the wide reach of the manuscript through social media and news outlets. The majority of social media correspondences have come from Thai accounts whereas news outlets were mostly from the United States and various European or Asian countries. Analyzed by Altmetric score, the report was within the top 5% of all research outputs ever scored by Altmetric. Finally, Google Trend data indicates that fish pedicure interest decreased thereafter to the lowest levels in the past decade after the case report was published, signifying its likely effect on diminishing public interest. This case report and analysis of its news/social media reach emphasize the importance of literature/media outlets in informing patients and the public of adverse effects. As fish pedicures continue to be popular both in the US and overseas, appropriate education of the public remains important in preventing complications.

RESUMEN

Onychomycosis is a common and significant nail condition causing both physical and social impairment. Since patients often search for health information online, the accuracy of this information has become important. In this study, we sought to assess the reliability and comprehensibility of accessible internet information for patients searching for onychomycosis. We identified the top search engine hits, evaluating websites on several categories: Accountability, Quality of Medical Information, Readability, Display, Support Features, and Transparency/Disclosures. Utilizing a pro forma based on established internet codes of conduct, website readability scores, and peer-reviewed papers, we objectively analyzed and scored the most commonly-listed websites on onychomycosis. Fifty-one total websites were reviewed with a maximum possible overall score of 43. The mean overall score for all websites was 20 and 1/43 (range, 4-35) with varied Accountability (mean, 4.9/10; range, 0-10) and Quality (mean, 6.4/13; range,1-12/13). Readability was poor overall with only 1/3 of sites meeting the acceptable 7th grade reading level for patients. In addition, while sites such as the American Academy of Dermatology website were well-organized and highly readable (Readability score, 5/5), this may compromise the quality of medical information presented (Quality score, 6/13). Because online education materials set the expectations and concerns of patients with onychomycosis, the variability in website reliability necessitates more efficient and regulated methods of presenting health information.

RESUMEN

Subcutaneous phaeohyphomycosis is a chronic fungal infection usually found on the lower extremity and feet of agricultural workers in the tropics. It can present with various skin manifestations, verrucous to nodular plaques, and is caused by multiple species of fungi. Laboratory confirmation requires skin samples for pathology and fungal cultures. Cure, often difficult in resource-poor countries, requires months of antifungal therapy. We describe the cases of three men from Ethiopia who were seen and are being treated by American doctors who traveled there on a medical mission.

RESUMEN

Tibiotalocalcaneal arthrodesis stabilized with retrograde intramedullary nail fixation is associated with a high incidence of complications. This is especially true when performed with a bulk structural allograft and poor soft tissue quality. In select high-risk limb salvage cases, we have augmented tibiotalocalcaneal arthrodesis procedures stabilized using retrograde intramedullary nail fixation with a vascularized pedicled fibular onlay bone graft. We present the data from 10 such procedures with a mean follow-up period of 10.9 ± 5.4 (range 6 to 20) months involving 10 patients (9 males and 1 female). The etiology was avascular osteonecrosis of the talus and/or distal tibia and a resultant large volume cavitary bone defect (8 ankles), severe equinocavovarus contracture (1 ankle), and failed total ankle replacement (1 ankle). A frozen femoral head bulk allograft was used twice, a whole frozen talus allograft once, and a freeze-dried calcaneal allograft once. The fibula was mobilized with intact musculoperiosteal perforating branches of the peroneal artery as a vascularized pedicle onlay bone graft fixated with a screw and washer construct. The mean fibular graft length was 10.2 ± 2.3 cm. The mean interval to radiographic fusion was 2.6 ± 0.6 months and to weightbearing was 3.1 ± 1.4 months. Two stable bulk allograft-host bone and fibular graft-host bone nonunions occurred after intramedullary nail hardware failure. Tibiotalocalcaneal arthrodesis augmented by vascularized pedicled fibular graft stabilized with retrograde compression intramedullary nail fixation offers a reliable option for complex salvage situations when few other options exist.

RESUMEN

Introduction: Skin ulcers can be challenging to diagnose and manage, particularly with comorbid autoimmune and gastrointestinal diseases. Occam's razor encourages the simplest explanation to guide care, but reconsideration must occur when intervention proves futile. Case Presentation: We report the case of a 70-year-old male, with a 17-year history of expanding pretibial skin ulcer, presumed by prior care providers to be pyoderma gangrenosum related to Crohn's disease. A surgical biopsy performed upon presentation to our institution revealed basal cell carcinoma of the skin, invasive to the proximal tibia with associated deep infection, prompting transfemoral amputation. Conclusion: This report is written as a reminder to reconsider a diagnosis and consider seeking additional expertise when a patient's condition progressively worsens despite intervention. Earlier diagnosis likely would have facilitated therapeutic limb salvage care.

RESUMEN

Neuroinflammation and the underlying dysregulated immune responses of microglia actively contribute to the progression and, likely, the initiation of Alzheimer's disease (AD). Fine-tuned therapeutic modulation of immune dysfunction to ameliorate disease cannot be achieved without the characterization of diverse microglial states that initiate unique, and sometimes contradictory, immune responses that evolve over time in chronic inflammatory environments. Because of the functional differences between human and murine microglia, untangling distinct, disease-relevant reactive states and their corresponding effects on pathology or neuronal health may not be possible without the use of human cells. In order to profile shifting microglial states in early AD and identify microglia-specific drivers of disease, we differentiated human induced pluripotent stem cells (iPSCs) carrying a familial AD PSEN2 mutation or its isogenic control into cerebral organoids and quantified the changes in cytokine concentrations over time with Luminex XMAP technology. We used partial least squares (PLS) modeling to build cytokine signatures predictive of disease and age to identify key differential patterns of cytokine expression that inform the overall organoid immune milieu and quantified the corresponding changes in protein pathology. AD organoids exhibited an overall reduction in cytokine secretion after an initial amplified immune response. We demonstrate that reduced synapse density observed in the AD organoids is prevented with microglial depletion. Crucially, these differential effects of dysregulated immune signaling occurred without the accumulation of pathological proteins. In this study, we used microglia-containing AD organoids to quantitatively characterize an evolving immune milieu, made up of a diverse of collection of activation patterns and immune responses, to identify how a dynamic, overall neuroinflammatory state negatively impacts neuronal health and the cell-specific contribution of microglia.

RESUMEN

Alzheimer's disease is a neurodegenerative disorder characterized by progressive amyloid plaque accumulation, tau tangle formation, neuroimmune dysregulation, synapse an neuron loss, and changes in neural circuit activation that lead to cognitive decline and dementia. Early molecular and cellular disease-instigating events occur 20 or more years prior to presentation of symptoms, making them difficult to study, and for many years amyloid-ß, the aggregating peptide seeding amyloid plaques, was thought to be the toxic factor responsible for cognitive deficit. However, strategies targeting amyloid-ß aggregation and deposition have largely failed to produce safe and effective therapies, and amyloid plaque levels poorly correlate with cognitive outcomes. However, a role still exists for amyloid-ß in the variation in an individual's immune response to early, soluble forms of aggregates, and the downstream consequences of this immune response for aberrant cellular behaviors and creation of a detrimental tissue environment that harms neuron health and causes changes in neural circuit activation. Here, we perform functional magnetic resonance imaging of awake, unanesthetized Alzheimer's disease mice to map changes in functional connectivity over the course of disease progression, in comparison to wild-type littermates. In these same individual animals, we spatiotemporally profile the immune milieu by measuring cytokines, chemokines, and growth factors across various brain regions and over the course of disease progression from pre-pathology through established cognitive deficit. We identify specific signatures of immune activation predicting hyperactivity followed by suppression of intra- and then inter-regional functional connectivity in multiple disease-relevant brain regions, following the pattern of spread of amyloid pathology.

RESUMEN

BACKGROUND: Equity, diversity and inclusion (EDI) in the healthcare field are crucial in meeting the healthcare needs of a progressively diverse society. In fact, a diverse healthcare workforce enables culturally sensitive care, promotes health equity and enhances the understanding of various needs and patients' viewpoints, potentially resulting in more effective patient treatment and improved patient outcomes. Despite this, information on the effectiveness of policies or programmes promoting EDI in health institutions is scarce. The objective of this systematic review is to assess the effects and outcomes of EDI programmes in healthcare institutions. METHODS: We will conduct Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant systematic review of studies on EDI programmes and describe their effects and outcomes in healthcare institutions. We will search PubMed, Scopus, Web of Science, CINAHL and PsycINFO databases. Selected studies will include randomised control trials (RCTs), non-RCTs and cross-sectional studies published either in English or French. Quality appraisal of studies and a narrative synthesis of extracted data will be conducted as well as a meta-analysis if possible. The quality of evidence in this review will be assessed by the Grades of Recommendation, Assessment, Development and Evaluation. ANTICIPATED RESULTS: We anticipate that this systematic review will reveal information on the effect of EDI programmes and their outcomes in healthcare institutions. We expect this information will provide insights that will lead to improvements in designing EDI policies and programmes in healthcare institutions. ETHICS AND DISSEMINATION: No ethical clearance is required for this study as no primary data will be collected. The final manuscript will be submitted to a journal for publication. In addition to this, the results of the study will also be disseminated through conference presentations to inform the research and clinical practice. REVIEW REGISTRATION: This protocol has been registered with the International Prospective Register of Systematic Reviews; registration number CRD42024502781.

RESUMEN

BACKGROUND: Electrolytes (sodium, potassium, calcium, magnesium, chloride, phosphate) are required in specific amounts for proper functioning of the human body. Although the body has different organ systems, such as the kidneys, that regulate electrolyte levels in the blood, electrolyte abnormalities occur frequently in people with eating disorders. The objective of this review will be to examine the association between electrolyte imbalances and adverse outcomes in people with eating disorders. METHODS: A systematic review of studies on eating and electrolyte disorders shall be conducted. Electronic searches shall be done in the Ovid MEDLINE, EMBASE, and PsycINFO databases. Selected studies shall include randomized control trials (RCTs), non-randomized controlled trials, and cross-sectional studies published in English or French. Quality appraisal of studies and a narrative synthesis of extracted data shall be conducted. DISCUSSION: This review will synthesize existing evidence on electrolyte abnormalities in people with eating disorders. It will identify the type of electrolyte imbalances, their impact, and outcomes in people with eating disorders. We anticipate that information that will be useful to policy makers and clinicians in designing better policies to prevent eating disorders and or manage people with eating disorders shall be elucidated in this study. DISSEMINATION: The final manuscript will be submitted for publication in a journal. REVIEW REGISTRATION: This protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO); registration number CRD42023477497.

RESUMEN

INTRODUCTION: Increasing rates of liver transplantation and improved outcomes have led to greater numbers of transplant recipients followed up in non-transplant centres. Our aim was to document long-term clinical outcomes of liver transplant recipients managed in this 'hub-and-spoke' healthcare model. METHODS: A retrospective analysis of all adult patients who underwent liver transplantation between 1987 and 2016, with post-transplant follow-up in two non-transplant centres in the UK (Nottingham) and Canada (Ottawa), was performed. RESULTS: The 1-, 5-, 10- and 20-year patient survival rates were 98%, 95%, 87% and 62%, and 100%, 96%, 88% and 62% in the Nottingham and Ottawa groups, respectively (p=0.87). There were no significant differences between the two centres in 1-, 5-, 10- and 20-year cumulative incidence of death-censored graft-survival (p=0.10), end-stage renal disease (p=0.29) or de novo cancer (p=0.22). Nottingham had a lower incidence of major cardiovascular events (p=0.008). CONCLUSION: Adopting a new model of healthcare provides a means of delivering post-transplant patient care close to home without compromising patient survival and long-term clinical outcomes.

RESUMEN

In this study, we sought to objectively determine the accuracy and comprehensibility of online material with regard to subungual melanoma, a nail disease that is rare within the general population, yet has high incidence in certain patient groups, and carries a poorer prognosis than other forms of cutaneous melanoma. Because improved prognosis relies on early diagnosis, the dissemination of accurate, understandable information is an important factor in patient education and health. Using a pro forma designed to score website reliability, the accountability, quality, readability, display, support features, and transparency of the most commonly listed search engine hits related to subungual melanoma were analyzed. A total of 27 websites were assessed, with a mean overall score of 16.1 out of a maximum of 40 (range: 7-25). Accountability (mean: 3.4/10, range: 0-9) and quality (mean: 4/10, range: 0-9) varied among websites, while readability was poor overall, with only 22% of websites meeting the accepted seventh grade reading level for online health material. In addition, commonly visited websites for health information, including Wikipedia.org and Medscape.com, scored low in readability. Notably, the American Academy of Dermatology website was not listed under any search engine results for subungual melanoma. Our study demonstrates the variability in online materials with regard to subungual melanoma, stressing the importance of scrutinizing internet resources for accuracy and readability when presenting health material.

RESUMEN

Tinea pedis is a common condition seen in clinical practice and has a significant impact on quality of life. Recommendations of over-the-counter antifungal products based on consumer preferences may guide dermatologists in treating patients with tinea pedis and preventing onychomycosis recurrences. Our study aimed to determine consumer preferences of antifungal products for tinea pedis, focusing on features that may guide purchases and usage. A search was performed for antifungal products used to treat athlete's foot on Amazon.com as of 2018, and the top one percentile of over-the-counter products were sorted by rating and number of reviews. Functionality was the most cited positive feature (42% of comments) followed by cosmetic characteristics (14%). The median price of all products was $1.80 (range $0.33-$95.42), with solutions and balms associated with higher costs and soaks being the least expensive. Our study showed that the range of antifungal products available online for treatment and prevention of tinea pedis is large and variable in terms of type/vehicle, price, and ingredients. Physicians must counsel patients on the efficacy and Food and Drug Administration approval of listed ingredients, especially for those products associated with numerous supplementary claims.

RESUMEN

Background. Electronic consultation (eConsultation) is a potential strategy to improve access to specialist expertise and facilitate collaborative care models. The Champlain BASE eConsult service allows for asynchronous communication between primary care providers (PCP) and specialists on a secure, web-based system. HIV experts accessible include HIV physician specialists, HIV pharmacists, and social workers with expertise in HIV. Objective. This study aims to describe the use, value, and utility of this eConsultation service in the care of people living with HIV and to characterize the common question types and clinical topics asked by PCPs. Methods. We analyzed the data from eConsults sent to the HIV specialty group in Ontario's Champlain Local Health Integration Network between February 2015 and December 2017. Usage data and close-out survey responses were analyzed using descriptive statistics, eConsults were classified using a predefined list of validated taxonomy, and a thematic analysis was performed on the consultation logs to identify common clinical themes. Results. Among the 46 eConsults, the most common question type related to drug treatment (58.7%, n = 27) and management (19.6%, n = 9). The main clinical themes involved the care of significant complexities in people living with HIV, such as comorbidities and drug interactions, and suggestions of coordinated patient care. As well, eConsult was used for advice regarding pre-exposure prophylaxis for HIV-negative patients at risk of HIV infection. PCPs highly valued the eConsult service (average rating 4.8/5). Conclusion. Overall, this study demonstrates that eConsult provides an efficient and valuable service to PCPs caring for patients living with or at risk for HIV by improving access to HIV specialists and facilitating the delivery of team-based comprehensive care.

RESUMEN

PLAIN ENGLISH SUMMARY: Increasingly, health researchers are conducting their research in partnership with non-researchers such as patients and caregivers, advocacy groups, clinicians, and policymakers. The idea behind this partnership is to make research more relevant and appropriate. However, so far there is not much evidence about how this partnership or engagement actually affects research. We conducted an online survey of 12 teams in Canada that have engaged patients and other stakeholders in community based health research, partly as a requirement to obtain funding. We found that in many cases, the teams have engaged a wide variety and large number of stakeholders, and have involved them in many different stages of their research. Teams reported that their overall experience of this approach to research has been positive, but some challenges have been encountered along the way. Some teams found that it was difficult to communicate appropriately with all the stakeholders, and to keep them informed when research was going slowly. Other teams had trouble finding government representatives to work with. Several teams noted that engagement is time-consuming, and requires a lot of effort. Nevertheless, all teams reported that they had learned from the experience, and found it valuable. As a result, Canadian health care researchers are better positioned to engage with patients and other stakeholders in the future. ABSTRACT: Background Patient and other stakeholder engagement in research is increasingly important, but there is limited evidence of its impact. In 2013, the Canadian Institutes of Health Research launched a five-year Community Based Primary Health Care (CBPHC) initiative that funded 12 teams for innovative approaches to primary health care involving engagement with patients, communities, decision-makers, and clinicians across jurisdictions in Canada. The present study examines the extent of engagement by these teams, and the factors that affected it, either as challenges or opportunities. Methods We conducted a cross-sectional web-based survey across the 12 CBPHC Innovation Teams, in which we were also participants. We used a data collection tool developed by the Patient Centered Outcomes Research Institute that included both closed and open-ended questions. Results The quantitative data showed that the CBPHC Innovation teams have engaged with diverse stakeholders at different levels and in different stages of research. Almost all teams surveyed engaged with policymakers, most with clinicians and health system representatives, and more than half with patients, mostly at the level of consultation or collaboration. There were very few instances of stakeholder-led research reported. There was a near universal recognition of the importance of communications processes/tools in facilitating engagement, whereas time was the most commonly identified challenge. In almost all cases, challenges encountered were partially if not fully resolved.The qualitative findings showed that each team's engagement was contextualized by factors such as the jurisdictions and geographic scope of the project, the number and type of stakeholders engaged and their level of involvement. These intersected with the researchers' motivations for engagement, to give rise to diverse experiences, but ones that the CBPHC teams assessed positively as an approach to research. Conclusions Over the past five years, primary health care researchers in Canada have been actively engaging with patients and other stakeholders. The wide range, extent and nature of that engagement shows that these researchers have anticipated developments in this approach to research and are thus in a position to support and strengthen future efforts to understand the impact of this engagement on health care outcomes.
