Health-Related Quality of Life and Satisfaction in Atrial Fibrillation Patients on Anticoagulant Therapy: Differences between Vitamin K Antagonists and Direct Oral Anticoagulants; Results from the Multicentre REGUEIFA Registry.

Background: Oral anticoagulation (OAC) is pivotal in the clinical management of atrial fibrillation (AF) patients. Vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) prevent thromboembolic events, but information about the quality of life (QoL) and patient satisfaction in relation with the anticoagulant treatment is limited. Methods: REGUEIFA is a prospective, observational, and multicentre study that included patients with AF treated by cardiologists. We included patients treated with VKAs or DOACs. The EuroQol-5D (EQ-5D) questionnaire evaluated QoL, and the Anti-Clot Treatment Scale (ACTS) questionnaire investigated patient satisfaction with OAC. Results: A total of 904 patients were included (532 on VKA and 372 on DOACs). A total of 846 patients completed the EQ-5D questionnaire, with results significantly worse in patients on VKAs than on DOACs: more mobility limitations (37.6% vs. 24.2%, p < 0.001), more restriction in usual activities (24.7% vs. 18.3%, p = 0.026), more pain/discomfort (31.8% vs. 24.2%, p = 0.015), a lower visual analogue scale (VAS) score (66.4 ± 16.21 vs. 70.8 ± 15.6), and a lower EQ-D5 index (0.79 ± 0.21 vs. 0.85 ± 0.2, p < 0.001). After adjusting for baseline characteristics, VKA treatment was not an independent factor towards worse EQ-5D results. Also, 738 patients completed the ACTS questionnaire, and burden and profit scores were lower in patients on VKAs than for DOACs (52.1 ± 8.4 vs. 55.5 ± 6.8, p < 0.001 and 11.1 ± 2.4 vs. 11.8 ± 2.6, p < 0.001, respectively). The negative impact score was higher for VKAs than for DOACs (1.8 ± 1.02 vs. 1.6 ± 0.99, p < 0.001), with a general positive impact score lower for VKAs than for DOACs (3.6 ± 0.96 vs. 3.8 ± 1.02, p < 0.001). Conclusions: Patients on VKA have more comorbidity and worse EQ-5D and VAS scores than those on DOACs. VKA has a greater burden and higher negative impact on the patient's life than DOACs.

Translating the behaviour change technique taxonomy version 1 into Spanish: Methodology and validation.

Background: Precise and unequivocal specification of intervention content is key to facilitating the accumulation and implementation of knowledge. The Behaviour Change Technique Taxonomy v1 (BCTTv1) is the most widely used classification of behaviour change techniques (BCTs), providing a shared, standardized vocabulary to identify the active ingredients of behavioural interventions. However, the BCTTv1 is only available in English and this hampers its broad use and adoption. The aim of the present article is to report the process of translation of the BCTTv1 into Spanish. Methods: A bilingual team led the translation of the BCTTv1, involving seven iterative steps: (i) establish a Committee, (ii) forward translation from English to Spanish, (iii) back translation from Spanish to English, (iv) comparison of original BCTTv1 and back translation, (v) opportunistic comparison against an independent BCTTv1 translation, (vi) empirical testing, and (vii) final Committee review. Results: Changes as a result of the translation process included relabelling BCTs, amending definitions, and fixing conceptual and grammatical inconsistencies, yielding the final version. Very satisfactory inter-coder reliability in BCT identification was observed as part of the empirical testing (i.e., prevalence and bias-adjusted kappa scores > 0.8). Conclusions: This work provides the Spanish-speaking population with a rigorous and validated BCTTv1 translation which can be used in both research and practice to provide a greater level of intervention detail for evidence synthesis, comparison, and replication of behaviour change interventions. The translation process described here may prove helpful to guide future translation efforts in behavioural science and beyond.

Behaviour change interventions use specific techniques (for example, providing information or setting up goals) to promote beneficial changes such as increasing physical activity or cutting down carbon emissions. Having a unifying framework for describing these techniques can help us describe studies more consistently and so better integrate research findings. The Behaviour Change Technique Taxonomy v1 (BCTTv1) is the most popular classification of intervention content. However, the BCTTv1 is only available in English and this makes it difficult for the taxonomy to be widely used as English is not the first language of so many across the world. The aim of the present article is to report the process of translation of the BCTTv1 into Spanish. A bilingual team led the translation of the BCTTv1, involving seven iterative steps: (i) establish a Committee, (ii) a first (forward) translation from English to Spanish, (iii) a second (back) translation from Spanish to English, (iv) comparison of original BCTTv1 and back translation, (v) opportunistic comparison against an independent BCTTv1 translation developed by a different research group, (vi) testing whether researchers can consistently apply the translated taxonomy, and (vii) final Committee review. Changes because of the translation process included relabelling some of the techniques, amending definitions, and fixing conceptual and grammatical inconsistencies, resulting in the final version. Results after using the final translated BCTTv1 suggest researchers can consistently apply the translated taxonomy to different behaviour change interventions. This study provides researchers and practitioners with a translation of the BCTTv1 that can be used to better specify behaviour change interventions in Spanish-speaking countries or other countries with large Spanish-speaking populations. The translation methodology described here could benefit the research community more broadly by informing future translation efforts of other research tools and resources.

Main pulmonary artery diameter related to pneumonia severity.

The diameter (mPAD) of the main pulmonary artery (pulmonary artery trunk) is a crucial indicator for cardiovascular health and prognoses in various conditions. Its enlargement is associated with increased mortality and severity in COVID-19-related pneumonia. However, its relevance to non-COVID pneumonia remains uncertain. The aim of this study was to establish an association between mPAD and the severity of non-COVID pneumonia. Eligible participants with qualified Chest Computed Tomography scans from November 2019 to February 2023 were recruited to a cross-sectional retrospective study. They were stratified into pneumonia and non-pneumonia cohorts. Exclusion criteria included pulmonary hypertension, polytrauma, lung neoplasia, or a history of pulmonary stenosis repair. The mPAD was measured in both groups, and medical records were reviewed to identify comorbidities. Pulmonary CT data were classified by pattern and severity, and the mPAD was measured perpendicularly to the long axis of the artery at the point of bifurcation on an axial slice. Analysis of 380 CT scans (52.6% men, 47.4% women; mean age 52.88 ± 17.58) revealed a significant difference in mPAD between pneumonia and non-pneumonia cases (mean difference: 1.19 mm, 95% CI [0.46, 1.92], p = 0.001). Age correlated positively with mPAD (r = 0.231, 95% CI [0.028, 0.069], p < 0.0001), and this correlation persisted after adjusting for confounders (r = 0.220, 95% CI [0.019, 0.073], p = 0.001). Ordinal logistic regression indicated 1.28 times higher odds of severe pneumonia with a larger diameter. The study highlights associations between mPAD, pneumonia, and severity, suggesting clinical relevance. Furthermore, the mPAD should be carefully considered in defining severity criteria for adverse outcomes in pneumonia patients. Further research is needed to refine clinical criteria on the basis of these findings.

Abdominal cocoon syndrome (sclerosing encapsulated peritonitis) causing small bowel occlusion in a patient with gastric bypass.

A rare condition, sclerosing encapsulating peritonitis, is characterized by a fibrotic membrane forming over the bowels, leading to intestinal obstruction. In this case of a 56-year-old male patient with a history of laparoscopic gastric bypass, a computed tomography scan showed findings indicative of the condition. Extensive adhesiolysis was performed, and biopsies confirmed the presence of fusiform cells (D2-40 positive on immunochemistry) resembling fibroblasts, within dense collagenous peritoneal tissue sheets, typical of sclerosing encapsulating peritonitis. The prevalence of this condition is uncertain, and diagnosis typically requires a peritoneal biopsy due to the nonspecific clinical presentation.

La peritonitis esclerosante encapsulada es una condición rara caracterizada por una membrana fibrótica que se genera sobre las asas intestinales causando cuadros de oclusión intestinal. Se presenta el caso de un paciente varón de 56 años con antecedente de derivación gastroyeyunal por laparoscopia que presenta oclusión intestinal. Se realizó tomografía computada que evidenció sitio de transición previo al sitio de anastomosis. Se realizó de anastomosis extensa y toma de biopsias. Histológicamente se observó engrosamiento de la membrana peritoneal, células fusiformes (D2-40 positivo en inmunohistoquímica) similares a fibroblastos con láminas de colágeno peritoneal denso. La peritonitis esclerosante encapsulada es una patología de prevalencia desconocida. El cuadro clínico es inespecífico y el diagnóstico definitivo es por patología con biopsia peritoneal.

Tympanostomy Tube Otorrhea: Microbiological Differences Between Children with and Without Cleft Palate.

OBJECTIVE: To characterize and compare microbiological profiles in tympanostomy tube otorrhea for children with and without cleft palate. DESIGN: Retrospective cohort study. SETTING: Pediatric otolaryngology and multidisciplinary cleft/craniofacial clinic at a single tertiary care center. PATIENTS: Children with and without cleft palate <18 years of age who underwent tympanostomy tube placement between 2017-2021. MAIN OUTCOME MEASURES: Otopathogen profiles and antibiotic resistance patterns in ear culture specimens obtained in children presenting for treatment of recalcitrant post-tympanostomy tube otorrhea. RESULTS: Of the 886 children with tympanostomy tubes placed between 2017-2021, 345 (38.9%) had clinically significant otorrhea defined as requiring at least one otolaryngology visit for treatment. Children with cleft palate had higher rates of otorrhea (50.0% versus 35.7%; P < .01). In the 128 cultures obtained, Staphylococcus aureus was the most common organism in both groups present in 39.8% of cultures; 49% were methicillin-resistant (MRSA). Pseudomonas aeruginosa was also frequently isolated (20.0% versus 23.4%, P = .69) in children with and without cleft palate. Collectively, fluoroquinolone resistance was observed in 68.6% and 27.6% of the S. aureus and P. aeruginosa isolates, respectively, however, no differences in fluoroquinolone resistance were observed between cleft and non-cleft cohorts. Corynebacterium species were isolated more frequently in children with cleft palate (26.7% versus 6.1%, P < .01), a finding of unclear significance. CONCLUSIONS: Recalcitrant post-tympanostomy tube otorrhea is more common in children with cleft palate. MRSA was the most common isolate, which was commonly resistant to first-line fluoroquinolone therapy.

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.

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.

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.

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.

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)

Sensor for Real-Time Glucose Measurement in Aqueous Media based on Nanomaterials Incorporating an Artificial Neural Network Algorithm on a System-On-Chip / Sensor para Medición de Glucosa en Tiempo Real para Medios Acuosos basado en Nanomateriales Incorporando un Algoritmo de Red Neuronal Artificial en un Sistema en Chip

Abstract The aim of this paper is to present the development of a real-time measurement system for glucose in aqueous media. The proposed system incorporates two lines of research: i) design, synthesis, and implementation of a non-enzymatic electrochemical sensor of Multi-Walled Carbon Nanotubes with Copper nanoparticles (MWCNT-Cu) and ii) design and implementation of a machine learning algorithm based on an Artificial Neural Network Multilayer Perceptron (ANN-MLP), which is embedded in an ESP32 SoC (System on Chip). From the current data that is extracted in real-time during the oxidation-reduction process to which an aqueous medium is subjected, it feeds the algorithm embedded in the ESP32 SoC to estimate the glucose value. The experimental results show that the nanostructured sensor improves the resolution in the amperometric response by identifying an ideal place for data collection. For its part, the incorporation of the algorithm based on an ANN embedded in a SoC provides a level of 97.8 % accuracy in the measurements. It is concluded that incorporating machine learning algorithms embedded in low-cost SoC in complex experimental processes improves data manipulation, increases the reliability of results, and adds portability.

Resumen El objetivo de este artículo es presentar el desarrollo de un sistema de medición en tiempo real de glucosa en medios acuosos. El sistema que se implementa incorpora dos lineas de investigación: i) diseño, síntesis e implementación de un sensor electroquímico no enzimático de Nanotubos de Carbono de Pared Múltiple con nanopartículas de Cobre (NTCPM-Cu) y ii) diseño e implementación de un algoritmo de aprendizaje automático basado en una Red Neuronal Perceptrón Multicapa (RN-PM), embebido en un ESP32 SoC (Sistema en Chip). Un dato de corriente que se extrae en tiempo real durante el proceso de oxidación-reducción a la que se somete un medio acuoso, alimenta el algoritmo embebido en el ESP32 para estimar el valor de glucosa. De los resultados experimentales se demuestra que el sensor nanoestructurado mejora la resolución en la respuesta amperométrica al identificar un lugar ideal para la toma de datos. Por su parte, la incorporación del algoritmo basado en una RN embebido en SoC otorga un nivel de 97.8 % de exactitud en la mediciones. Se concluye que incorporar algoritmos de aprendizaje automático embebidos en SoC de bajo costo en procesos experimentales complejos, mejora la manipulación de datos, incrementa la confiabilidad en resultados y adiciona portabilidad.

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.
