Design and Research of Wearable Fall Protection Device for the Elderly / 中国医疗器械杂志

A protective device was designed that can be worn on the elderly, which consists of protective airbag, control box and protective mechanism. The combined acceleration, combined angular velocity and human posture angle are selected as the parameters to determine the fall, and the threshold algorithm and SVM algorithm are used to detect the fall. The protective mechanism is an inflatable device based on CO2 compressed air cylinder, and the equal-width cam structure is applied to its transmission part to improve the puncture efficiency of the compressed gas cylinder. A fall experiment was designed to obtain the combined acceleration and angular velocity eigenvalues of fall actions (forward fall, backward fall and lateral fall) and daily activities (sitting-standing, walking, jogging and walking up and down stairs), showing that the specificity and sensitivity of the protection module reached 92.1% and 84.4% respectively, which verified the feasibility of the fall protection device.

Experiencia de un modelo de atención con uso de telemedicina en niños/as con nutrición parenteral domiciliaria / Pandemic and highly complex pediatric outpatient care in a public hospital. Experience of a care model with the use of telemedicine in children with home parenteral nutrition

Introducción: Los pacientes que reciben nutrición parenteral domiciliaria (NPD) en seguimiento desde el Hospital requieren un monitoreo que debió modificarse por la pandemia por SARS-CoV-2. Objetivo: Valorar la utilización y el impacto en los resultados, de estrategias alternativas a la atención presencial de pacientes con NPD, empleando telemedicina, durante el inicio de la pandemia por SARS-CoV-2, comparándolas con las prácticas habituales previas. Materiales y métodos: Estudio analítico descriptivo retrospectivo que analizó el monitoreo, la evolución y las complicaciones de pacientes con NPD asistidos en el Hospital en el período previo a la pandemia (1/4/2019 y 31/3/2019) y durante su primer año (1/4/2020 a 31/3/2021), basado en la revisión de historias clínicas y bases de datos de complicaciones. Resultados: Las características demográficas, diagnósticos, procedencia y provisión de la NPD fueron similares en los dos períodos. Durante el período de la pandemia se redujeron en forma significativa el número de controles presenciales y aumentaron los realizados por telemedicina en forma sincrónica (con una modalidad pautada previamente), y los controles por profesionales locales. La participación de los cuidadores en los procedimientos de administración de la NPD aumentó en pandemia. Las tasas de complicaciones, re-internaciones, el número de inicios y suspensiones de tratamiento fueron similares en ambos períodos. Conclusiones: En pandemia fue posible implementar y monitorizar la NPD utilizando telemedicina sin observar afectación significativa de la evolución, las complicaciones de la enfermedad y del tratamiento. El seguimiento mediante telemedicina sincrónica resultó útil y se incorporará como una herramienta más al monitoreo habitual sin reemplazarlo

Introduction: Patients receiving home parenteral nutrition (HPN) under follow-up from the Hospital require monitoring that had to be modified due to the SARSCoV-2 pandemic. Objective: To assess the use and the impact on the results of other care strategies for patients with HPN, using telemedicine, during the beginning of the SARS CoV2 pandemic, compared with previous usual practices.Materials and methods: Retrospective descriptive analytical study that analyzed the monitoring, evolution and complications of patients with HPN assisted in the Hospital, in the period before pandemic ( 4/1/2019 to 3/31/2020) and during the first year of SARS CoV-2 pandemic (4/1/2020 to 3/31/2021), according to data obtained from medical records and databases. Results: demographic characteristics, diagnoses, place of residence and HPN provision were similar in both periods. During the pandemic period, the number of face-to-face controls were significantly reduced and those carried out by telemedicine synchronously, and by local professionals increased. The participation of caregivers in the administration procedures of the HPN increased in the pandemic period. The rates of complications, readmissions, number of initiations and suspensions of home treatment were similar in both periods. Conclusions: It was possible to implement and monitor HPN during pandemic. The evolution and complications of the disease and treatment were not significantly affected. Synchronous telemedicine follow-up was successfully useful and will be incorporated as another tool to regular monitoring

Technical Difficulties in the Implementation of the Continuous Glucose Monitoring System / 中国医疗器械杂志

The continuous glucose monitoring system (CGMS) has been clinically applied to monitor the dynamic change of the subcutaneous interstitial glucose concentration which is a function of the blood glucose level by glucose sensors. It can track blood glucose levels all day along, and thus provide comprehensive and reliable information about blood glucose dynamics. The clinical application of CGMS enables monitoring of blood glucose fluctuations and the discovery of hidden hyperglycemia and hypoglycemia that are difficult to be detected by traditional methods. As a CGMS needs to work subcutaneously for a long time, a series of factors such as biocompatibility, enzyme inactivation, oxygen deficiency, foreign body reaction, implant size, electrode flexibility, error correction, comfort, device toxicity, electrical safety, et al. should be considered beforehand. The study focused on the difficulties in the technology, and compared the products of Abbott, Medtronic and DexCom, then summarized their cutting-edge. Finally, this study expounded some key technologies in dynamic blood glucose monitoring and therefore can be utilized as a reference for the development of CGMS.

Use of a mobile application for the control of anticoagulation with warfarin: a cluster randomized controlled clinical trial - Ijui/RS/Brazil

Abstract To evaluate the effectiveness of an anticoagulation protocol adapted in a mobile application (appG) for patients using warfarin. This was a cluster randomized controlled clinical trial carried out in basic health centers of Ijui, RS, Brazil, between April and October 2017. The appG was installed on the cell phones of all physicians belonging to the intervention group. Primary outcomes were bleeding and thrombosis, and secondary outcomes were changes in the dose of warfarin, use of new drugs, drug interactions, search for health services, and remaining on the target international normalized ratio. Thirty-three patients belonging to 11 basic health centers were included in this study. From these, 15 patients were in the intervention group which used the appG, and 18 were in the control group. After 6 months, patients in the appG group had fewer bleeding events (7% versus 50%, p-value=0.028) and a lower weekly dose of warfarin (29.3 ± 9.7 mg versus 41.7 ± 12.5 mg, p-value=0.030) when compared to the control group. The anticoagulation protocol adapted in a mobile app reduced bleeding in patients using warfarin.

Introduction : La prévalence de l'asthme au niveau national est inconnue. L'objectif était de déterminer la prévalence hospitalière de l'asthme et la sensibilisation aux pneumallergènes standards.Patients et Méthodes : Il s'agit d'une étude transversale, rétrospective qui a consisté en l'analyse descriptive de 164 dossiers de patients asthmatiques reçus pour consultation au CHU de Libreville sur une période d'activité de 36 mois. La mesure du VEMS pré et post-bronchodilatateur ainsi que les prick-tests ont été réalisés. Les extraits standardisés suivants étaient testés : Dermatophagoïdes pteronyssinus et farinae, les phanères (chien et chat), les plantes vertes (Cynodon dactylon) et les moisissures (Alternaria sp). Résultats : Des 2798 patients reçus en consultation de pneumologie, 164 l'étaient pour un asthme soit une fréquence 5,8%. Parmi les 164 patients asthmatiques 59,8%(n=98) étaient des femmes avec un sex-ratio à 0,67. La moyenne d'âge de la population d'étude était de 31±18,1 ans, des extrêmes de 5 et 81 ans. Plus de la moitié des patients résidait en milieu urbain (59,7%), et était sans revenu (50,7%). L'asthme était associé à la rhinite allergique dans 72,6%. Seuls 45 patients avaient réalisé les prick tests parmi lesquels la sensibilisation aux acariens (n=37/45 ; 82,2%) était fréquente et dominée par Dermatophagoïdes pteronyssinus (n=32/37 ; 86,5%). La sensibilisation à Blomia tropicalis était de 73,0% (n=27/37). La sensibilisation aux phanères d'animaux (chiens et chats) était observée chez 9 patients (n=9/45 ; 20,0%). Aucune sensibilisation à l'Alténaria sp n'a été relevée. Le déficit ventilatoire obstructif proximal et distal a été observé dans 45,8% des cas (n=60/131).Conclusion : La prévalence de l'asthme est relativement élevé dans notre contexte d'exercice. Le taux sensibilisation révélé est le témoin d'une forte pression allergénique exercée par l'environnement domestique

Introduction: The national prevalence of asthma is unknown. The objective was to determine the hospital prevalence of asthma and sensitization to standard airborne allergens. Patients and Methods: This is a cross-sectional, retrospective study which consisted of the descriptive analysis of 164 records of asthmatic patients received for consultation at the University Hospital of Libreville over a period of activity of 36 months. Measurement of pre- and post-bronchodilator FEV1 as well as prick-tests were performed. The following standardized extracts were tested: Dermatophagoides pteronyssinus and farinae, skin appendages (dog and cat), green plants (Cynodon dactylon) and molds (Alternaria sp).Results: Of the 2798 patients seen in a pulmonology consultation, 164 were for asthma, i.e. a frequency of 5.8%. Among the 164 asthmatic patients 59.8% (n=98) were women with a sex ratio of 0.67. The average age of the study population was 31 ± 18.1 years, extremes of 5 and 81 years. More than half of the patients lived in urban areas (59.7%), and had no income (50.7%). Asthma was associated with allergic rhinitis in 72.6%. Only 45 patients had performed prick tests,among which sensitization to house dust mites (n=37/45; 82.2%) was frequent and dominated by Dermatophagoides pteronyssinus (n=32/37; 86.5%). Sensitization to Blomia tropicalis was 73.0% (n=27/37). Sensitization to animal dander (dogs and cats) was observed in 9 patients (n=9/45; 20.0%). No sensitization to Altenaria sp was noted. Proximal and distal obstructive ventilatory deficit was observed in 46.5% of cases (n=60/130).Conclusion: The prevalence of asthma is relatively high in our exercise context. The sensitization rate revealed is the witness of a strong allergenic pressure exerted by the domestic environment.

Remote cardiac rehabilitation is a good alternative of outpatient cardiac rehabilitation in the COVID-19 era

BACKGROUND@#In the wake of the coronavirus disease 2019 (COVID-19) pandemic, people need to practice social distancing in order to protect themselves from SARS-CoV-2 infection. In such stressful situations, remote cardiac rehabilitation (CR) might be a viable alternative to the outpatient CR program.@*METHODS@#We prospectively investigated patients hospitalized for heart failure (HF) with a left ventricular ejection fraction of < 50%. As for patients who participated in the remote CR program, telephone support was provided by cardiologists and nurses who specialized in HF every 2 weeks after discharge. The emergency readmission rate within 30 days of discharge was compared among the outpatient CR, remote CR, and non-CR groups, and the EQ-5D score was compared between the outpatient CR and remote CR groups.@*RESULTS@#The participation rate of HF patients in our remote CR program elevated during the COVID-19 pandemic. As observed in the outpatient CR group (n = 69), the emergency readmission rate within 30 days of discharge was lower in the remote CR group (n = 30) than in the non-CR group (n = 137) (P = 0.02). The EQ-5D score was higher in the remote CR group than in the outpatient CR group (P = 0.03) 30 days after discharge.@*CONCLUSIONS@#Remote CR is as effective as outpatient CR for improving the short-term prognosis of patients hospitalized for heart failure post-discharge. This suggests that the remote CR program can be provided as a good alternative to the outpatient CR program.

The study on extraction method of pulse rate variability in daily unsupervised state / 生物医学工程学杂志

The extraction of pulse rate variability(PRV) in daily life is often affected by exercise and blood perfusion. Therefore, this paper proposes a method of detecting pulse signal and extracting PRV in post-ear, which could improve the accuracy and stability of PRV in daily life. First, the post-ear pulse signal detection system suitable for daily use was developed, which can transmit data to an Android phone by Bluetooth for daily PRV extraction. Then, according to the state of daily life, nine experiments were designed under the situation of static, motion, chewing, and talking states, respectively. Based on the results of these experiments, synchronous data acquisition of the single-lead electrocardiogram (ECG) signal and the pulse signal collected by the commercial pulse sensor on the finger were compared with the post-auricular pulse signal. According to the results of signal wave, amplitude and frequency-amplitude characteristic, the post-ear pulse signal was significantly steady and had more information than finger pulse signal in the traditional way. The PRV extracted from post-ear pulse signal has high accuracy, and the accuracy of the nine experiments is higher than 98.000%. The method of PRV extraction from post-ear has the characteristics of high accuracy, good stability and easy use in daily life, which can provide new ideas and ways for accurate extraction of PRV under unsupervised conditions.

Noninvasive Medical Tools for Evaluating Voiding Pattern in Real Life / 대한배뇨장애요실금학회지

Voiding dysfunction is a common disease that contributes to a lower quality of life and has an increased prevalence in the elderly population. Noninvasive and objective methods such as uroflowmetry (UFM) and voiding diaries (VDs) are essential for exact diagnosis and effective treatment of this condition because patients with different causes of voiding dysfunction can complain of the same lower urinary tract symptoms. Further, different treatment options can be determined based on the diagnosis made from these symptoms. In order to improve the quality of UFM and VDs and to provide a convenient testing environment, several advances have been made by previous investigators. In this study, we investigate the history and technological mechanisms of UFM and VDs. We also aim to review UFM from the viewpoint of clinical and at-home uses, including the recently proposed toilet-shaped UFM and electronic VDs.

Design of a Front-end Device of Heart Rate Variability Analysis System Based on Photoplethysmography / 生物医学工程学杂志

Heart rate variability (HRV) is the difference between the successive changes in the heartbeat cycle, and it is produced in the autonomic nervous system modulation of the sinus node of the heart. The HRV is a valuable indicator in predicting the sudden cardiac death and arrhythmic events. Traditional analysis of HRV is based on a multielectrocardiogram (ECG), but the ECG signal acquisition is complex, so we have designed an HRV analysis system based on photoplethysmography (PPG). PPG signal is collected by a microcontroller from human's finger, and it is sent to the terminal via USB-Serial module. The terminal software not only collects the data and plot waveforms, but also stores the data for future HRV analysis. The system is small in size, low in power consumption, and easy for operation. It is suitable for daily care no matter whether it is used at home or in a hospital.

Angioplastía coronaria ambulatoria seguida de telemonitoreo post alta en pacientes estables / Safety of ambulatory coronary angioplasty followed by tele-monitoring for 3 days after discharge

Introducción: La angioplastía coronaria ambulatoria (APA) es habitualmente realizada, bajo ciertos criterios de seguridad y selección de pacientes. Nuestro objetivo fue realizar monitoreo telemédico en todas las angioplastías ambulatorias, durante tres días posterior al procedimiento. Método: Análisis prospectivo de las angioplastías ambulatorias realizadas en el Hospital Dr. Sótero del Río entre Marzo y Octubre del 2014. Se excluyó an-gioplastías de tronco coronario izquierdo, bifurcaciones, en contexto de síndrome coronario agudo y falla cardíaca. Se realizó monitoreo de presión arterial, frecuencia cardíaca, saturación de oxígeno, electrocardiograma (ECG) abreviado (D2 largo), presencia de síntomas, complicaciones del sitio de punción y adherencia a medicamentos durante 3 días. Se dispuso de alertas protocolizados para cada item, en una plataforma de monitoreo telemédico 24/7. En el análisis se consideró género, edad, factores de riesgo cardiovascular clásicos, medicamentos, presencia de síntomas, signos vitales, complicaciones del sitio de punción, rehospitalizaciones, tamaño del stent, vaso tratado y morbimortalidad. Resultados: Se realizaron 52 APA, suceptibles de ingresar al programa de monitoreo. Todas fueron realizadas por via radial. Un 68% de sexo masculino, edad promedio de 60,4 años, hipertensos 67%, diabétios 29%, dislipidémicos 37%, fumadores 45% con antecedentes familiares de cardiopatía coronaria 14%, angioplastía previa 53%, cirugía de revascularización previa 3,8%. Todos los procedimientos se efectuaron vía transradial. 23% recibió más de 1 stent. Ningún paciente presentó complicaciones durante el procedimiento y el resultado angiográfico final fue satisfactorio. Durante la monitori-zación, 8 pacientes presentaron alza de presión arterial, uno de los cuales fue resuelto en el servicio de urgencia, mientras que en los restantes se ajustó la dosis de medicamentos mediante consulta telefónica. Cuatro pacientes tuvieron dolor toráxico, 3 de ellos citados a control el día siguiente con ECG y en solo 1 se decidió nuevo estudio coronario, la cual demostró Stent permeable, sin evidencia de complicaciones. Ocho pacientes tuvieron complicaciones del sitio de punción, pero en un sólo caso fue hematoma, resuelto espontáneamente y en los 7 restantes dolor u hormigueo. No se registraron complicaciones mayores, como trombosis intra stent, accidentes cerebrovasculares o muerte. Conclusión: La monitorizacion cardíaca post an-gioplastía ambulatoria en pacientes coronarios estables parece una herramienta muy útil, que permite conocer la real evolución de los pacientes en su domicilio después del procedimiento y, además, corregir eventuales complicaciones. En este grupo ningún paciente presentó alguna complicación grave.

Background: Ambulatory coronary angioplasty (A-PTCA) has been performed in adequately selected patients. Our aim was to evaluate the feasibility and safety of adding post discharge tele-monitoring in patients undergoing A-PTCA Methods: Patients undergoing A-PTCA at Hospital Sotero del Rio (Santiago, Chile) from March to April 2014 were prospectively selected for addition of tele-monitoring. Patients with main left disease, lesions at bifurcations, those with evolving acute coronary syndromes, and those with heart failure were excluded. Tele monitoring for 3 days included arterial blood pressure, heart rate, arterial oxygen saturation, abbreviated (Lead II) ECG, symptoms, evaluation of puncture site and adherence to drug therapy. Pre designed continuous alerts were set in the monitoring system. Demographic and angiographic characteristics were recorded. Results: in 52 procedures inclusion and exclusion criteria were fulfilled and patients were included in the study. Mean age was 60.4 years old and 68% were males. Hypertension was present in 67%, diabetes en 29%, dyslipidemia in 37%, and and 45% smoked. 53% had prior PTCA and 3.8% prior CABG. PTCA was performed via the radial artery in all patients and 32% received more than 1 stent. No patient developed complications during or inmediately after PTCA. Angiographic result was satisfactory in all subjects. During tele-monitoring 8 patients presented high blood pressure: one was derived to the ER, all others had their medications appropiately adjusted.
