Evaluating Mixed Reality as a Tool for Patient Education of Facial Fractures.

Background: Patients may be educated about facial fractures using two-dimensional computed tomography (2DCT); however, three-dimensional mixed reality (3DMR) goggles may improve patient education by delivering content in an immersive environment. Objective: To compare the effectiveness of 2DCT and 3DMR formats used for patient education on facial fractures, as measured by surveys. Methods: In this prospective, randomized, crossover study, video tutorials intended for facial fracture informed consent were created in 2DCT and 3DMR formats from a single CT data set of a zygomaticomaxillary complex (ZMC) fracture. Subjects were randomly assigned into two groups. Group 1 (n = 25) viewed the 2DCT tutorial, answered self-assessment and information recall surveys, viewed the 3DMR tutorial, repeated the prior surveys as well as a comparison survey. Group 2 (n = 25) followed the same sequence but viewed the 3DMR tutorial and then the 2DCT tutorial. Results: Participants (n = 50) had no differences in age (group 1-51.9 years/standard deviation [SD] 20.9; group 2-44.7 years/SD 17.6 years; p = 0.223), gender (group 1-10 male/15 female; group 2-11 male/14 female; p = 0.999), college education level (group 1-25 yes; group 2-25 yes; p = 0.844), or prior 2DCT or 3DMR experience (group 1-9 yes/16 no; group 2-13 yes/12 no; p = 0.393). The 3DMR format was preferred over 2DCT (p < 0.05), and it was reported to enhance understanding as compared to 2DCT (p < 0.05). No differences for information recall were noted (p = 0.753). Conclusion: In this study, participants preferred 3DMR goggles over 2DCT for a simulated ZMC fracture-informed consent.

Introducing Sialendoscopy in a Veteran Population: Effect on Benign Salivary Disease Treatment.

OBJECTIVE: To compare rates of sialadenectomy in a veteran population before and after introduction of sialendoscopy. MATERIALS AND METHODS: All Veterans Affair (VA) Northern California Healthcare System (NCHS) encounters from 2006 to 2021 for benign obstructive salivary etiologies were identified using International Classification of Disease 9/10 codes. This cohort was then cross referenced with Current Procedural Terminology codes to identify patients who underwent a procedure for their salivary pathologies. The rates of sialadenectomy and minimally invasive procedures were measured before and after sialendoscopy was introduced to the VA NCHCS in 2016. Data was obtained via chart review and demographic information, diagnosis, and procedure type were extracted. Rates of sialadenectomy, minimally invasive procedures, and other patient and procedural characteristics were compared between the Pre-Sialendoscopy Era (PSE) and Sialendoscopy Era (SE). Statistical analysis was performed using Microsoft Excel (Microsoft, version 16.66). RESULTS: An increasing number of patients per year sought care for benign obstructive salivary pathology in the SE when compared to the PSE cohort and a higher rate of female patients were treated in the SE cohort. A simultaneous reduction in sialadenectomy rates and increase in minimally invasive procedure rates was observed in the SE. Sialendoscopy represented most of the increase in minimally invasive techniques, but there was a slight increase in other procedure types. Submandibular gland obstructive pathologies required the most procedures and resulted in the most gland excisions. CONCLUSION: This retrospective review strongly suggests introducing sialendoscopy reduced the incidence of sialadenectomy for benign non-tumor obstructive pathology in this VA NCHS population. Further prospective studies are needed to evaluate this in a more generalized setting.

Martial arts, combat sports, and mental health in adults: A systematic review.

Martial arts (MA) and combat sports (CS) are physical activities that may be associated with health-related outcomes. The aim of this systematic review was to synthesize and evaluate the available evidence on the relationship between MA and CS training and mental health of adult practitioners (≥18 years). CochraneLibrary, EBSCOhost, Web-of-Science, and Scopus databases were searched up to September 2022 for measures of self-related constructs, ill-being and well-being, cognition and brain structure/function, in adult MA/CS practitioners. Seventy cross-sectional and two longitudinal studies were retained and submitted to risk of bias assessments through an adapted version of the Cochrane Collaboration's Tool. Associations between MA/CS practice and self-related constructs were inconclusive for both consistency and strength of evidence. Limited evidence of significant associations emerged for sub-domains of ill-being (i.e., externalizing and internalizing emotion regulation), and well-being. In regard to cognitive and brain structural/functional variables, evidence of positive association with MA/CS practice was consistent with respect to perceptual and inhibition abilities but limited with respect to attention and memory. Evidence on negative associations of boxing with changes of brain structure integrity due to concussions was also inconclusive. Functional imaging techniques could shed light onto brain activation mechanisms underlying complex cognitive performance. In relation to moderators, mixed results were found for activity exposure, expertise, level of competitive engagement (which often covary with the length of training) and sex and type of MA/CS. The MA/CS' multifaceted nature may produce different, sometimes conflicting outcomes on mental health. Studies on MA/CS represent a flourishing research area needing extensive improvement in theoretical and practical approaches.

Effectiveness of holistic mobile health interventions on diet, and physical, and mental health outcomes: a systematic review and meta-analysis.

Background: Good physical and mental health are essential for healthy ageing. Holistic mobile health (mHealth) interventions-including at least three components: physical activity, diet, and mental health-could support both physical and mental health and be scaled to the population level. This review aims to describe the characteristics of holistic mHealth interventions and their effects on related behavioural and health outcomes among adults from the general population. Methods: In this systematic review and meta-analysis, we searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, Scopus, China National Knowledge Infrastructure, and Google Scholar (first 200 records). The initial search covered January 1, 2011, to April 13, 2022, and an updated search extended from April 13, 2022 to August 30, 2023. Randomised controlled trials (RCTs) and non-randomised studies of interventions (NRSIs) were included if they (i) were delivered via mHealth technologies, (ii) included content on physical activity, diet, and mental health, and (iii) targeted adults (≥18 years old) from the general population or those at risk of non-communicable diseases (NCDs) or mental disorders. Studies were excluded if they targeted pregnant women (due to distinct physiological responses), individuals with pre-existing NCDs or mental disorders (to emphasise prevention), or primarily utilised web, email, or structured phone support (to focus on mobile technologies without exclusive human support). Data (summary data from published reports) extraction and risk-of-bias assessment were completed by two reviewers using a standard template and Cochrane risk-of-bias tools, respectively. Narrative syntheses were conducted for all studies, and random-effects models were used in the meta-analyses to estimate the pooled effect of interventions for outcomes with comparable data in the RCTs. The study was registered in PROSPERO, CRD42022315166. Findings: After screening 5488 identified records, 34 studies (25 RCTs and 9 pre-post NRSIs) reported in 43 articles with 5691 participants (mean age 39 years, SD 12.5) were included. Most (91.2%, n = 31/34) were conducted in high-income countries. The median intervention duration was 3 months, and only 23.5% (n = 8/34) of studies reported follow-up data. Mobile applications, short-message services, and mobile device-compatible websites were the most common mHealth delivery modes; 47.1% (n = 16/34) studies used multiple mHealth delivery modes. Of 15 studies reporting on weight change, 9 showed significant reductions (6 targeted on individuals with overweight or obesity), and in 10 studies reporting perceived stress levels, 4 found significant reductions (all targeted on general adults). In the meta-analysis, holistic mHealth interventions were associated with significant weight loss (9 RCTs; mean difference -1.70 kg, 95% CI -2.45 to -0.95; I2 = 89.00%) and a significant reduction in perceived stress levels (6 RCTs; standardised mean difference [SMD] -0.32; 95% CI -0.52 to -0.12; I2 = 14.52%). There were no significant intervention effects on self-reported moderate-to-vigorous physical activity (5 RCTs; SMD 0.21; 95%CI -0.25 to 0.67; I2 = 74.28%) or diet quality scores (5 RCTs; SMD 0.21; 95%CI -0.47 to 0.65; I2 = 62.27%). All NRSIs were labelled as having a serious risk of bias overall; 56% (n = 14/25) of RCTs were classified as having some concerns, and the others as having a high risk of bias. Interpretation: Findings from identified studies suggest that holistic mHealth interventions may aid reductions in weight and in perceived stress levels, with small to medium effect sizes. The observed effects on diet quality scores and self-reported moderate-to-vigorous physical activity were less clear and require more research. High-quality RCTs with longer follow-up durations are needed to provide more robust evidence. To promote population health, future research should focus on vulnerable populations and those in middle- and low-income countries. Optimal combinations of delivery modes and components to improve efficacy and sustain long-term effects should also be explored.

Barriers and enablers to local active travel during COVID-19: A case study of Streetspace interventions in two London boroughs.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, UK local authorities increased emergency active travel interventions. This study aimed to understand what aspects of temporary Streetspace for London schemes represent barriers or enablers to walking and cycling for short local journeys. Methods: Focusing on two Inner London boroughs, we conducted 21 semi-structured stakeholder interviews and sampled 885 public comments about Streetspace schemes. We triangulated the data in a thematic analysis to identify barriers and enablers, which were categorised using the Capability, Opportunity, Motivation, Behaviour (COM-B) model. Results: Opportunity and motivation factors were reflected in the barriers (accessibility and integration of the schemes; controversy, dissatisfaction, and doubt) and enablers (new routes and spaces; sustainability and health beliefs) and mixed themes (changes to traffic and appeal of the area; feelings of safety). Capability was not reflected in the main themes. Conclusions: Although aspects of Streetspace schemes were seen to enable active travel, our findings suggest that additional processes to address the acceptability, fairness, and unintended consequences of emergency interventions will be important to their long-term success for health and sustainability.

Primary Cutaneous Follicle Center Lymphoma of the Eyelid in a Young Man.

A 20-year-old male presented with a fast-growing nodule in his right inferior eyelid, no relevant history was obtained. Final histopathologic diagnosis of primary cutaneous follicle center lymphoma (CD20+, CD10+, bcl6+, bcl10+, mum1+, PAX5+, and bcl2-) was determined. The patient had a complete negative systemic work-up, and 3 cycles of consisting of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy were completed. The initial histopathologic diagnosis had been a non-Hodgkin diffuse large B-cell lymphoma which is an infrequent lymphoma type for this location too. To our knowledge, this is the youngest person reported presenting with an eyelid primary cutaneous follicle center lymphoma.

Development of "LvL UP 1.0": a smartphone-based, conversational agent-delivered holistic lifestyle intervention for the prevention of non-communicable diseases and common mental disorders.

Background: Non-communicable diseases (NCDs) and common mental disorders (CMDs) are the leading causes of death and disability worldwide. Lifestyle interventions via mobile apps and conversational agents present themselves as low-cost, scalable solutions to prevent these conditions. This paper describes the rationale for, and development of, "LvL UP 1.0″, a smartphone-based lifestyle intervention aimed at preventing NCDs and CMDs. Materials and Methods: A multidisciplinary team led the intervention design process of LvL UP 1.0, involving four phases: (i) preliminary research (stakeholder consultations, systematic market reviews), (ii) selecting intervention components and developing the conceptual model, (iii) whiteboarding and prototype design, and (iv) testing and refinement. The Multiphase Optimization Strategy and the UK Medical Research Council framework for developing and evaluating complex interventions were used to guide the intervention development. Results: Preliminary research highlighted the importance of targeting holistic wellbeing (i.e., both physical and mental health). Accordingly, the first version of LvL UP features a scalable, smartphone-based, and conversational agent-delivered holistic lifestyle intervention built around three pillars: Move More (physical activity), Eat Well (nutrition and healthy eating), and Stress Less (emotional regulation and wellbeing). Intervention components include health literacy and psychoeducational coaching sessions, daily "Life Hacks" (healthy activity suggestions), breathing exercises, and journaling. In addition to the intervention components, formative research also stressed the need to introduce engagement-specific components to maximise uptake and long-term use. LvL UP includes a motivational interviewing and storytelling approach to deliver the coaching sessions, as well as progress feedback and gamification. Offline materials are also offered to allow users access to essential intervention content without needing a mobile device. Conclusions: The development process of LvL UP 1.0 led to an evidence-based and user-informed smartphone-based intervention aimed at preventing NCDs and CMDs. LvL UP is designed to be a scalable, engaging, prevention-oriented, holistic intervention for adults at risk of NCDs and CMDs. A feasibility study, and subsequent optimisation and randomised-controlled trials are planned to further refine the intervention and establish effectiveness. The development process described here may prove helpful to other intervention developers.

Holistic mHealth interventions for the promotion of healthy ageing: protocol for a systematic review.

INTRODUCTION: Maintaining physical and mental health is essential for healthy ageing. It can be supported by modifying lifestyle factors such as physical activity and diet. Poor mental health, in turn, contributes to the opposing effect. The promotion of healthy ageing may therefore benefit from holistic interventions integrating physical activity, diet and mental health. These interventions can be scaled up to the population level by using mobile technologies. However, systematic evidence regarding the characteristics and effectiveness of such holistic mHealth interventions remains limited. This paper presents a protocol for a systematic review that aims to provide an overview of the current state of the evidence for holistic mHealth interventions, including their characteristics and effects on behavioural and health outcomes in general adult populations . METHODS AND ANALYSIS: We will conduct a comprehensive search for randomised controlled trials and non-randomised studies of interventions published between January 2011 and April 2022 in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, Scopus, China National Knowledge Infrastructure and Google Scholar (first 200 records). Eligible studies will be mHealth interventions targeting general adult populations with content on physical activity, diet and mental health. We will extract information on all relevant behavioural and health outcomes, as well as those related to intervention feasibility. Screening and data extraction processes will be carried out independently by two reviewers. Cochrane risk-of-bias tools will be used to assess risk of bias. We will provide a narrative overview of the findings from eligible studies. With sufficient data, a meta-analysis will be conducted. ETHICS AND DISSEMINATION: Ethical approval is not required because this study is a systematic review based on published data. We intend to publish our findings in a peer-reviewed journal and present the study at international conferences. PROSPERO REGISTRATION NUMBER: CRD42022315166.

Exploring the potential of mobile health interventions to address behavioural risk factors for the prevention of non-communicable diseases in Asian populations: a qualitative study.

BACKGROUND: Changing lifestyle patterns over the last decades have seen growing numbers of people in Asia affected by non-communicable diseases and common mental health disorders, including diabetes, cancer, and/or depression. Interventions targeting healthy lifestyle behaviours through mobile technologies, including new approaches such as chatbots, may be an effective, low-cost approach to prevent these conditions. To ensure uptake and engagement with mobile health interventions, however, it is essential to understand the end-users' perspectives on using such interventions. The aim of this study was to explore perceptions, barriers, and facilitators to the use of mobile health interventions for lifestyle behaviour change in Singapore. METHODS: Six virtual focus group discussions were conducted with a total of 34 participants (mean ± SD; aged 45 ± 3.6 years; 64.7% females). Focus group recordings were transcribed verbatim and analysed using an inductive thematic analysis approach, followed by deductive mapping according to perceptions, barriers, facilitators, mixed factors, or strategies. RESULTS: Five themes were identified: (i) holistic wellbeing is central to healthy living (i.e., the importance of both physical and mental health); (ii) encouraging uptake of a mobile health intervention is influenced by factors such as incentives and government backing; (iii) trying out a mobile health intervention is one thing, sticking to it long term is another and there are key factors, such as personalisation and ease of use that influence sustained engagement with mobile health interventions; (iv) perceptions of chatbots as a tool to support healthy lifestyle behaviour are influenced by previous negative experiences with chatbots, which might hamper uptake; and (v) sharing health-related data is OK, but with conditions such as clarity on who will have access to the data, how it will be stored, and for what purpose it will be used. CONCLUSIONS: Findings highlight several factors that are relevant for the development and implementation of mobile health interventions in Singapore and other Asian countries. Recommendations include: (i) targeting holistic wellbeing, (ii) tailoring content to address environment-specific barriers, (iii) partnering with government and/or local (non-profit) institutions in the development and/or promotion of mobile health interventions, (iv) managing expectations regarding the use of incentives, and (iv) identifying potential alternatives or complementary approaches to the use of chatbots, particularly for mental health.

Seafood consumption as a source of exposure to high production volume chemicals: A comparison between Catalonia and the Canary Islands.

Seafood plays an important role in diet because of its health benefits. However, the fact that chemical compounds such as high production volume chemicals may be present in seafood means that its consumption can be a potential risk for population. To assess the occurrence of HPVs and estimate the exposure and risk associated with their consumption, specimens of the most consumed seafood species in Catalonia and the Canary Islands, Spain, were collected and analysed. Results showed higher levels of HPVs in samples from Catalonia and a prevalence of phthalate esters and benzenesulfonamides over the other target compounds in samples from both locations. Multivariate analysis showed spatial differences between the mean concentration profiles of HPVs for the samples from Catalonia and the Canary Islands. Exposures were higher for the samples from Catalonia, although the intake of HPVs via seafood was not of any real concern in either of the locations.

Determination of benzothiazoles, benzotriazoles and benzenesulfonamides in seafood using quick, easy, cheap, effective, rugged and safe extraction followed by gas chromatography - tandem mass spectrometry: Method development and risk assessment.

The common use of benzothiazoles, benzotriazoles and benzenesulfonamides has led to widespread ubiquity in several environmental matrices. Their occurrence in edible fish could represent an additional exposure route for the population. The present study aims to develop a method for the simultaneous determination of these three compound families in seafood samples. Based on QuEChERS extraction, different salt combinations and clean-up strategies have been evaluated to achieve the highest recoveries while reducing the matrix effect in low and high lipidic content species. The best results were obtained with the original method salts and the lipid-selective push-through clean-up, which combined with gas chromatography-tandem mass spectrometry led to recoveries between 50 and 112% with negligible matrix effects and method detection limits between 0.15-9.50 ng g-1 dw. The application of the method to commercially available samples confirmed the presence of BTs as well as BSAs, with the latter being determined in seafood for the first time. Exposure and risk assessment calculations indicated a minor risk for the population when consuming fish.

High production volume chemicals in the most consumed seafood species in Tarragona area (Spain): Occurrence, exposure, and risk assessment.

Seafood consumption has become a potential exposure route towards high production volume chemicals (HPVs) due to the pathway of these compounds reaching the aquatic environment via industrial and domestic discharges. The present study focuses on the determination of phthalate esters (PAEs), organophosphate esters (OPEs), benzothiazoles (BTs), benzotriazoles (BTRs) and benzenesulfonamides (BSAs) in the ten most consumed fish species in Catalonia. A total of 120 commercially available seafood specimens were purchased throughout February 2019-February 2020 in three different stores (supermarket, local market, and local fishmonger) of the city of Tarragona, Spain, to cover the most typical places where seafood can be obtained. ΣOPEs, ΣBTs, ΣBSAs and ΣPAEs concentrations ranged between 5.99 and 139.45 ng g-1 w.w., 8.41-54.08 ng g-1 w.w., 8.38-304.47 ng g-1 w.w and 2.86-323.80 ng g-1 w.w., respectively. BTRs were not detected in any of the samples. PAEs and BSAs had similar contributions which combined represented nearly the 70% of detected compounds and sardine resulted as the species with the higher HPVs mean concentration. No considerable threat was posed due to the individual intake of these compounds via seafood consumption.

Intoxicación por plaguicidas en autopsias medicolegales. Tegucigalpa 2014-2020 / Poisoning by pesticides in medicolegal autopsies. Tegucigalpa 2014- 2020

Justificación: Los plaguicidas han provocado un significativo problema de salud pública ya que han generado una importante carga a la mortalidad y a la morbilidad. Los suicidios con plaguicidas representan alrededor de un tercio de todos los suicidios en el mundo. Objetivo: Caracterizar las muertes relacionadas a plaguicidas, sometidas a autopsia médico legal en la Dirección de Medicina Forense de Tegucigalpa durante los años 2014- 2020. Metodología: Se consultó la base de datos digital la Dirección de Medicina Forense, encontrando 255 casos relacionados a muerte por plaguicidas de los que se seleccionaron 215 casos con expediente completo y disponible. Los cálculos estadísticos se realizaron con el programa PSPP. Resultados: Se encontraron 215 casos, el 58% eran hombres y el 42% mujeres, 54% eran solteros y 29% en unión libre. Sin escolaridad 11%, primaria incompleta 20%, primaria completa 15%, secundaria incompleta 12%, secundaria completa 10%. Respecto a la ocupación de los fallecidos, los oficios domésticos fue la más frecuente entre las mujeres y la agricultura entre los hombres. El 65% eran personas jóvenes menores de 40 años con una media de edad de 35 años (rango 8- 89a). La manera de muerte más frecuente fue suicida con el 71%. El plaguicida más utilizado como instrumento de muerte fue el fosfuro de aluminio (66%).Conclusión: La mayoría de las muertes por intoxicación con plaguicidas fueron suicidas; hombres jóvenes, menores de 40 años, solteros, con escolaridad que no sobrepasaba la secundaria; utilizaron las pastillas de fosfuro de aluminio como instrumento de autolesión. Se requiere estudiar más detalladamente el uso de tóxicos en general y de los plaguicidas en particular como instrumentos de autolesión y se evidencia la necesidad imperiosa de habilitar medidas de regulación para la comercialización y campañas de educación en la población para el uso y manejo adecuado...(AU)

Utility of Screening for Obstructive Sleep Apnea with the Pediatric Sleep Questionnaire (PSQ) in Children with Craniofacial Anomalies.

OBJECTIVE: To determine the accuracy of the Pediatric Sleep Questionnaire (PSQ) as a screening tool for obstructive sleep apnea in children with craniofacial anomalies. DESIGN: Retrospective cohort study. SETTING: Multidisciplinary cleft and craniofacial clinic at a tertiary care center. PATIENTS: Children with craniofacial anomalies 2 to ≤18 years of age who both completed a PSQ screen and underwent polysomnography (PSG) without interval surgery. MAIN OUTCOME MEASURES: Sensitivity and specificity of the PSQ in detecting an obstructive apnea-hypopnea index (AHI) ≥ 5 events/hour. RESULTS: Fifty children met study criteria, with 66% (n = 33) having an associated syndrome. Mean patient age at time of PSQ was 9.6 + 4.0 years. Overall, 33 (64%) screened positive on the PSQ, while 20 (40%) had an AHI ≥ 5. The sensitivity and specificity for identifying AHI ≥ 5 was 70% and 40%, respectively. With subgroup analysis, the sensitivity and specificity were higher (100% and 50%) in children with non-syndromic palatal clefting but lower (65% and 31%) in children with a syndrome or chromosomal anomaly. There was no correlation detected between PSQ score and AHI severity (p = 0.25). The mean obstructive AHI in the study population was 10.1 ± 22.7 despite 44% (n = 22) undergoing prior adenotonsillectomy. CONCLUSIONS: The PSQ was less sensitive and specific in detecting an AHI ≥ 5 in children with craniofacial anomalies than in a general population, and particularly poor in for children with syndrome-associated craniofacial conditions. Given the high prevalence of OSA in this patient population, a craniofacial-specific validated screening tool would be beneficial.

Amiloidosis cardiaca: descripción de una serie de 143 casos / Cardiac amyloidosis: Description of a series of 143 cases

Introducción y objetivos: Recientemente se han producido importantes avances en el diagnóstico y tratamiento de la amiloidosis cardiaca (AC). Nos propusimos realizar una descripción actualizada de sus 2 tipos más frecuentes: la AC por transtirretina (AC-ATTR) y la AC por cadenas ligeras (AC-AL).MétodosRegistro prospectivo de pacientes diagnosticados de AC en 7 hospitales de Galicia entre el 1 de enero de 2018 y el 30 de junio de 2020. Se recogieron variables relativas a características clínicas, pruebas complementarias, supervivencia y causas de muerte.ResultadosSe incluyeron de forma consecutiva 143 pacientes con AC, 128 AC-ATTR (89,5%) y 15 AC-AL (10,5%). La edad media fue de 79,6±7,7 años y un 23,8% fueron mujeres. La mayoría de los pacientes con AC-ATTR se diagnosticaron de forma no invasiva (87,5%). En la exploración física, un 35,7, un 35 y un 7% de los pacientes presentaban el signo de Popeye, contractura de Dupuytren y macroglosia, respectivamente. La supervivencia a los 12 y 24 meses fue del 92,1 y el 76,2% en el grupo AC-ATTR, y del 78,6 y el 61,1% en el grupo AC-AL (p=0,152). La causa de muerte fue cardiovascular en el 80,8% de la cohorte.ConclusionesLa AC-ATTR puede ser diagnosticada en la mayoría de los casos de manera no invasiva y es la forma de AC más frecuente en la práctica clínica habitual. Además, parece observarse un aumento en la supervivencia a corto plazo de la AC que en parte podría deberse a los avances relacionados con su diagnóstico y tratamiento. (AU)

Introduction and objectives: Recently, there have been important advances in the diagnosis and treatment of cardiac amyloidosis (CA). Our aim was to provide an updated description of its 2 most frequent types: the transthyretin CA (ATTR-CA) and the light chain CA (AL-CA).MethodsProspective registry of patients with CA diagnosed in 7 institutions in Galicia (Spain) between January 1, 2018 and June 30, 2020. Variables related to clinical characteristics, complementary tests, survival and causes of death were collected.ResultsOne hundred and forty-three patients with CA were consecutively included, 128 ATTR-CA (89.5%) and 15 AL-CA (10.5%). Mean age was 79.6±7.7 years and 23.8% were women. Most patients with ATTR-CA were diagnosed non-invasively (87.5%). On physical examination, 35.7, 35 and 7% had Popeye's sign, Dupuytren's contracture and macroglossia, respectively. Twelve-month and 24-month survival was 92.1 and 76.2% in the ATTR-CA group, and 78.6 and 61.1% in the AL-CA group (P=.152). The cause of death was cardiovascular in 80.8% of the cohort.ConclusionsATTR-CA can be diagnosed non-invasively in most cases and it is the most common type of CA in routine clinical practice. Furthermore, an increase in the short-term survival of CA appears to be observed, which could be due to advances related to its diagnosis and treatment. (AU)

[Kimura's disease mimicking primary neoplasm of the parotid gland: A case report]. / Enfermedad de Kimura simulando neoplasia primaria de glándula parótida: Reporte de caso.

Background: Kimura's disease is an infrequent inflammatory disorder, of unknown etiology, with few reports outside of Asia. It presents as a nodule or tumor predominantly in the postauricular region, neck and parotid gland. It is histologically characterized by follicular hyperplasia with wellformed mantle zones, preservation of nodal architecture, prominent eosinophilic infiltrate in the germinal centers and interfollicular areas; and associated with elevated levels of IgE and peripheral eosinophilia. Clinical case: We present a case of a 23-year-old man from Mexico, he presented with a recurrent tumor in the right parotid gland, previously treated with surgical resection. Imaging studies were performed and a primary neoplasm of the salivary gland was suspected, he was treated with surgical resection. The histological diagnosis was Kimura's disease. Conclusions: Communication and divulgation of this rare inflammatory disorder expans the knowledge for the differential diagnosis of tumors of the head and neck, and salivary glands, mainly in men with peripheral eosinophilia and elevated IgE; it can sometimes simulate malignant neoplasms, leads to inadequate diagnostic and therapeutic approaches.

Introducción: la enfermedad de Kimura es un desorden inflamatorio poco frecuente, de etiología desconocida y raramente reportado fuera del continente asiático. Se presenta como un nódulo o tumor predominantemente en la región retroauricular, cervical o glándula parótida. Se caracteriza histológicamente por hiperplasia folicular con zonas del manto bien formadas, preservación de la arquitectura ganglionar, infiltrado eosinofílico prominente en los centros germinales y áreas interfoliculares; generalmente asociada a niveles elevados de IgE y eosinofilia periférica. Caso clínico: presentamos el caso de un hombre de 23 años, de origen mexicano que se presentó con un tumor recidivante a dos años de resección quirúrgica previa en glándula parótida derecha, se realizaron estudios de imagen y se sospechó de neoplasia primaria de glándula salival, fue tratado con resección quirúrgica. El diagnóstico histológico fue de enfermedad de Kimura. Conclusiones: la comunicación y difusión de este raro desorden inflamatorio amplía la base del conocimiento para el diagnóstico diferencial de tumores de cabeza y cuello, y glándulas salivales, predominantemente en hombres con eosinofilia periférica y elevación de IgE; que en ocasiones puede simular neoplasias malignas, llevando a abordajes diagnósticos y terapéuticos inadecuados.

Assessing Open Science practices in physical activity behaviour change intervention evaluations.

Objectives: Concerns on the lack of reproducibility and transparency in science have led to a range of research practice reforms, broadly referred to as 'Open Science'. The extent that physical activity interventions are embedding Open Science practices is currently unknown. In this study, we randomly sampled 100 reports of recent physical activity randomised controlled trial behaviour change interventions to estimate the prevalence of Open Science practices. Methods: One hundred reports of randomised controlled trial physical activity behaviour change interventions published between 2018 and 2021 were identified, as used within the Human Behaviour-Change Project. Open Science practices were coded in identified reports, including: study pre-registration, protocol sharing, data, materials and analysis scripts sharing, replication of a previous study, open access publication, funding sources and conflict of interest statements. Coding was performed by two independent researchers, with inter-rater reliability calculated using Krippendorff's alpha. Results: 78 of the 100 reports provided details of study pre-registration and 41% provided evidence of a published protocol. 4% provided accessible open data, 8% provided open materials and 1% provided open analysis scripts. 73% of reports were published as open access and no studies were described as replication attempts. 93% of reports declared their sources of funding and 88% provided conflicts of interest statements. A Krippendorff's alpha of 0.73 was obtained across all coding. Conclusion: Open data, materials, analysis and replication attempts are currently rare in physical activity behaviour change intervention reports, whereas funding source and conflict of interest declarations are common. Future physical activity research should increase the reproducibility of their methods and results by incorporating more Open Science practices.

Syncope in patients with transthyretin amyloid cardiomyopathy: clinical features and outcomes.

BACKGROUND: We aimed to describe the clinical characteristics, underlying causes and outcomes of syncope in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). METHODS: The clinical profile and underlying causes of syncopal episodes were reviewed in a cohort of 128 patients with ATTR-CM enrolled from January 2018 to June 2020 in a prospective multicentre registry in 7 hospitals of Galicia (Spain). After enrollment, patients were followed during a median period of 520 days. The effect of syncope on all-cause mortality was assessed by means of multivariate Cox´s regression. RESULTS: Thirty (23.4%) patients had a history of previous syncope as a clinical antecedent before being enrolled in the prospective phase of the registry, and 4 (3.1%) experienced a first episode of syncope thereafter. The estimated incidence density rate of syncope during the prospective follow-up period after registry enrollment was 71.9 episodes per 1000 patients-year (95% Confidence Interval (CI) 32.8-111.1). The estimated overall prevalence of syncope was 26.6% (95% CI 18.9%-34.2%). Cardiac arrhythmias (n = 11, 32.3%), structural diseases of the heart or great vessels (n = 5, 14.7%), a neurally mediated reflex (n = 6, 17.6%), and orthostatic hypotension (n = 4, 11.8%) were identified as probable underlying causes of syncope; in 8 (23.6%) patients, syncope remained unexplained. Patients with syncope had increased non-adjusted all-cause mortality than patients without it (univariate hazard-ratio 3.37; 95% CI 1.43-7.94). When other independent predictors of survival were added to the survival model, this association was no longer statistically significant (multivariate hazard-ratio 1.81, 95% CI 0.67-4.84). CONCLUSIONS: Syncope is frequent in patients with ATTR-CM. This study could not demonstrate an independent association between syncope and mortality in those individuals.Abbreviations: ATTR-CM: Transthyretin amyloid cardiomyopathy; CI: Confidence Interval; HF: Heart Failure; HR: Hazard Ratio; IQR: Interquartile rank; LVEF: Left Ventricular Ejection Fraction; NTproBNP: N-terminal pro-brain natriuretic peptide; SD: Standard Deviation; 99mTc-DPD: technetium-99m-labeled 3,3-diphosphono-1,2-propanodicarboxylic acid.

Neural Crest-Derived Stem Cells (NCSCs) Obtained from Dental-Related Stem Cells (DRSCs): A Literature Review on Current Knowledge and Directions toward Translational Applications.

Evidence from dental-related stem cells (DRSCs) suggests an enhanced potential for ectodermal lineage differentiation due to their neural crest origin. Growing evidence that DRSC cultures can produce cells with a neural crest-derived stem cell (NCSC)-like phenotype supports their potential for future therapeutic approaches for neurodegenerative diseases and nerve injuries. However, most of the evidence is limited to the characterization of DRSCs as NCSCs by detecting the expression of neural crest markers. Only a few studies have provided proof of concept of an improved neuro-glial differentiation or direct applicability in relevant models. In addition, a current problem is that several of the existing protocols do not meet manufacturing standards for transferability to a clinical scenario. This review describes the current protocols to obtain NCSCs from DRSCs and their characterization. Also, it provides important considerations from previous work where DRSCs were established and characterized as mesenchymal stromal cells but studied for their neuro-glial differentiation potential. The therapeutic advancement of DRSCs would depend on establishing protocols that can yield a neural crest-like phenotype efficiently, using appropriate manufacturing standards and testing them in relevant models of disease or injury. Achieving these conditions could then facilitate and validate the therapeutic potential of DRSC-NCSCs in regenerative therapies.

Validation of a semiological maneuver for the evaluation of spastic dynamic clubfoot: an approach based on the judgment of experts in physical medicine and rehabilitation.

BACKGROUND: The evaluation of spasticity of the plantar flexors in dynamic clubfoot is difficult due to the almost invariable concomitance of Achilles clonus, which is a semiological artifact. No description was found in the literature of a technique for inhibiting or reducing the discharge generated by Achilles clonus to allow a correct assessment of spasticity in this segment. AIM: Validation of a semiological maneuver that reduces or eliminates Achilles clonus for the adequate evaluation of spastic dynamic clubfoot. DESIGN: Multicenter cross-sectional study. SETTING: The study was conducted by 12 experts in physical medicine and rehabilitation from various clinics and hospitals in Colombia. POPULATION: Thirty-five adults with dynamic spastic clubfoot and Achilles clonus secondary to upper motor neuron syndrome who attended outpatient consultation at physical medicine and rehabilitation services in eight cities Colombia from August 2020 to February 2021. METHODS: The usual method for examining spastic plantar flexors was compared to the proposed semiological maneuver to evaluate the proposed maneuver contributed to the reduction or elimination of Achilles clonus to allow a more accurate measure of spasticity in this segment. Four dimensions were evaluated by the experts: time required for application, simplicity, effectiveness and clinical utility. A cutoff point was established to identify whether the maneuver was unacceptable, acceptable or excellent. RESULTS: The application of the maneuver was able to reduce or eliminate Achilles clonus as a masking sign of spasticity in the plantar flexors in 100% of the patients and was considered excellent in 77.1% of the cases for the four dimensions evaluated. A decrease in the degree of spasticity of the plantar flexors was observed when the maneuver was applied. CONCLUSIONS: The proposed maneuver reduces or eliminates Achilles clonus, which could allow a more precise evaluation of spasticity in this segment. All of the experts recommended including the maneuver in routine examinations of this population. CLINICAL REHABILITATION IMPACT: Applying the proposed maneuver could improve the selection of patients with spastic dynamic clubfoot who require specific treatment.
