Evaluación de signos vitales mediante una aplicación móvil en pacientes con insuficiencia cardiaca: ¿una oportunidad para la titulación remota? / Evaluation of vital signs through a mobile application in patients with heart failure: a opportunity for remote titration?

Resumen Antecedentes: Las consultas virtuales aumentaron exponencialmente, pero presentan como limitación la imposibilidad de valorar los signos vitales (SV), siendo especialmente útiles en los pacientes con insuficiencia cardiaca (IC) para titular medicación que modifica pronóstico. Este problema podría potencialmente solucionarse mediante una herramienta que pueda medir la presión arterial (PA) y frecuencia cardiaca (FC) de manera precisa, accesible y remota. Los teléfonos móviles equipados con tecnología de imágenes ópticas transdérmicas podrían cumplir con estos requisitos. Objetivo: Evaluar la precisión de una app basada en imagen óptica transdérmica para estimar SV en relación con la valoración clínica en pacientes con IC. Métodos: Estudio de cohorte prospectivo, se incluyeron pacientes evaluados en una unidad ambulatoria de IC de febrero a abril del 2022. Se valoró simultáneamente la PA y FC mediante la app y el examen clínico (PA con un esfigmomanómetro automatizado y FC por palpación braquial). Se realizaron tres mediciones por app y clínica en cada paciente, por dos médicos independientes, encontrándose ciegos a los resultados. Resultados: Se incluyeron 30 pacientes, con 540 mediciones de TA y de FC. Edad media de 66 (± 13) años, el 53.3% de sexo masculino. La fracción de eyección del ventrículo izquierdo media fue de 37 ± 15, con hospitalizaciones previas por IC el 63.3%, en CF II-III el 63.4%. La diferencia media entre la medición de la app y su medición de referencia clínica fue de 3.6 ± 0.5 mmHg para PA sistólica (PAS), 0.9 ± -0.2 mmHg para PA diastólica (PAD) y 0.2 ± 0.4 lpm para FC. Cuando se promedian las diferencias medias emparejadas para cada paciente, la media entre los 30 pacientes es de 2 ± 6 mmHg para PAS, -0.14 ± 4.6 mmHg para PAD y 0.23 ± 4 lpm para FC. Conclusión: La estimación de PA y FC por una app con tecnología de imagen óptica transdérmica fue comparable a la medición no invasiva en pacientes con IC, y cumple los criterios de precisión de la medición de PA en este estudio preliminar. La utilización de esta nueva tecnología de imagen óptica transdérmica brinda datos prometedores, que deberán ser corroborados en cohortes de mayor tamaño.

Abstract Background: Virtual consultations have increased exponentially, but a limitation is the inability to assess vital signs (VS). This is particularly useful in patients with heart failure (HF) for titrating prognosis-modifying medication. This issue could potentially be addressed by a tool capable of measuring blood pressure (BP) and heart rate (HR) accurately, remotely, and conveniently. Mobile phones equipped with transdermal optical imaging technology could meet these requirements. Objective: To evaluate the accuracy of a transdermal optical imaging-based app for estimating VS compared to clinical assessment in patients with HF. Methods: A prospective cohort study included patients evaluated in an HF outpatient unit between February and April 2022. BP and HR were simultaneously assessed using the app and clinical examination (BP with an automated sphygmomanometer and HR by brachial palpation). Three measurements were taken by both the app and clinic for each patient, by two independent blinded physicians. Results: Thirty patients were included, with 540 measurements of BP and HR. The mean age was 66 (± 13) years, 53.3% were male. The mean left ventricular ejection fraction was 37 ± 15, with 63.3% having previous hospitalizations for HF, and 63.4% in NYHA class II-III. The mean difference between the app measurement and its clinical reference measurement was 3.6 ± 0.5 mmHg for systolic BP (SBP), 0.9 ± -0.2 mmHg for diastolic BP (DBP), and 0.2 ± 0.4 bpm for HR. When averaging the paired mean differences for each patient, the mean across the 30 patients was 2 ± 6 mmHg for SBP, -0.14 ± 4.6 mmHg for DBP, and 0.23 ± 4 bpm for HR. Conclusion: The estimation of BP and HR by an app with transdermal optical imaging technology was comparable to non-invasive measurement in patients with HF and met the precision criteria for BP measurement in this preliminary study. The use of this new transdermal optical imaging technology provides promising data, which should be corroborated in larger cohorts.

mHealth Apps Delivering Early Intervention to Support Parents of Children With Autism Spectrum Disorder: A Scoping Review

Context: Early intervention, and parent-mediated intervention are effective in achieving early childhood development goals for children with autism spectrum disorder. There is a surge in mHealth technologies delivering such interventions. This review aims to explore the concept, context and methodology of implementation of such mHealth apps. Evidence Acquisition: A search was conducted using NICE (National Institute of Clinical Excellence) healthcare database, including keyword ‘early intervention,’ ‘mHealth,’ ‘parent support,’ ‘apps,’ and ‘autism.’ The quantitative, qualitative, mixed-methods, case reports, grey literature, systematic reviews, clinical trials, and feasibility studies of children between 2 to 6 years with ASD were included from inception of database to December, 2021. Web/ Internet-based or computer-dependent programs were excluded. The initial search yielded 3786 studies; 17 were finally included based on the inclusion and exclusion criteria. Result: Studies on a total of mhealth apps were reviewed. Nine apps, apart from TOBY (Therapy outcome by you), lacked a holistic approach and instead targeted a specific difficulty in autism. The provision of support to parents using apps was equally beneficial as in-person support, reduced costs, and improved outcomes in children. Conclusion: The review revealed limited evidence-based mHealth apps available currently in a community setting. This also underscores an opportunity for clinicians to re-direct parents towards evidence-based information and interventions.

Current situation and effect evaluation of mobile applications for physical activity management in China / 中华健康管理学杂志

Objective:To analyze the current situation and effect of mobile applications for physical activity management in China.Methods:In this systematic review, search terms such as “exercise”, “sports”, “exercise”, “physical activity” and “mobile health” were used to retrieve the applications for physical activity management in the IOS Application Store developed in mainland of China. Then the Mobile Application Rating Scale (MARS) and the Behavior Change Technology (BCT) were used to evaluate the quality of the applications and analyze the behavior change technologies that applications adopted. Moreover, a systematic review of relevant experimental studies was applied to summarize the effectiveness of the applications in promoting physical activity.Results:Total of 141 applications were included in this analysis, and 58 behavior change techniques in 16 categories were applied. The most frequently used 4 categories of BCT were behavior comparison (67.4%), repetition and substitution (67.4%), knowledge construction (67.4%), feedback and monitoring (58.2%). The overall objective quality score of MARS was 3.17±0.42, of which, the score of engagements, functionality, aesthetic design and information quality was 2.67±0.73, 3.75±0.54, 3.44±0.59 and 2.83±0.55, respectively. The number of BCT adopted in each application had a linear relationship with the application′s objective quality score in MARS ( B=0.023, 95% CI: 0.018-0.029) and user rating ( B=0.040, 95% CI: 0.019-0.060) (both P<0.001). A total of 4 articles were included to test the effects of techniques (i.e., physical activity behavior monitoring, physical activity planning and physical activity guidance) in 4 applications. The overall quality of the literatures was good. The main outcomes were physical activity duration (3 articles) and step count (1 article). Compared with those who did not use the application or only used the accelerometer to monitor physical activity, subjects who used the application to monitor physical activity had significant longer physical activity durations and step count (both P<0.05). Conclusions:The number, function and technology of physical activity management applications in China are abundant, but the quality of the applications is moderate. The number of BCT is an important factor in evaluating application′s quality, but its effect on behavior change is still not clear.

Cohort profile of the largest health & demographic surveillance system (Dibrugarh-HDSS) from North-East India

Dibrugarh Health and Demographic Surveillance System (Dibrugarh-HDSS), was started in the year 2019 with the objective to create the health and demographic database of a population from a defined geographical area and a surveillance system for providing technical assistance for the implementation of programmes and formulating intervention strategies for reducing disease morbidities and mortalities in the population. Dibrugarh-HDSS adopted a panel design and covered 60 contiguous villages and 20 tea gardens. Line listing of all the households was conducted and a unique identification number detailing State, district, village/tea garden and serial number was provided along with geotagging. Detailed sociodemographic variables, anthropometric measurements (subjects ?five years) and blood pressure data (subjects ?18 yr), disease morbidity and mortality were collected. All data were collected in pre-designed and pre-tested questionnaires using a mobile application package developed for this purpose. Dibrugarh-HDSS included a total of 106,769 individuals (rural: 46,762, tea garden: 60,007) with 52,934 males (49.6%) and 53,835 females (50.4%). The number of females per thousand males were significantly higher (1042 in tea garden vs. 985 in rural populations) in the tea-garden community as compared to the village population. More than one-third (35.1%) of tea populations were illiterate compared to the rural population (17.1%). Villagers had significantly higher body mass index than the tea-garden community. The overall prevalence of hypertension (adjusted for age) was 29.4 vs. 28.2 per cent, respectively, for the village and tea-garden population. For both these communities, males (village=30.8%, tea garden=31.1%) showed a higher prevalence of hypertension (adjusted for age) than females (village=28.2%, tea garden=25.8%). The findings of the present study give an insight into the profile of the native rural and tea-garden populations that will help to identify risk factors of different health problems, review the effectiveness of different ongoing programmes, implement intervention strategies for reducing morbidity and mortality and assist the State health authorities in prioritizing their resource allocation and implementation strategies.
