Wearables for Stress Management: A Scoping Review.

In recent years, wearable devices have been increasingly used to monitor people's health. This has helped healthcare professionals provide timely interventions to support their patients. In this study, we investigated how wearables help people manage stress. We conducted a scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) standard to address this question. We searched studies in Scopus, IEEE Explore, and Pubmed databases. We included studies reporting user evaluations of wearable-based strategies, reporting their impact on health or usability outcomes. A total of 6259 studies were identified, of which 40 met the inclusion criteria. Based on our findings, we identified that 21 studies report using commercial wearable devices; the most common are smartwatches and smart bands. Thirty-one studies report significant stress reduction using different interventions and interaction modalities. Finally, we identified that the interventions are designed with the following aims: (1) to self-regulate during stress episodes, (2) to support self-regulation therapies for long-term goals, and (3) to provide stress awareness for prevention, consisting of people's ability to recall, recognize and understand their stress.

ECG Standards and Formats for Interoperability between mHealth and Healthcare Information Systems: A Scoping Review.

Interoperability is defined as the ability of a system or device to communicate between different technologies and software applications. This allows the exchange and use of data in an efficient, precise, and robust way. The present article gives researchers and healthcare information systems developers a qualitative and quantitative synthesis of the state of knowledge related to data formats and data standards proposed for mHealth devices interoperability in healthcare information systems that retrieve and store ECG data. We carry out a scoping review to answer to following questions: (1) What digital data formats or data standards have been proposed for the interoperability of electrocardiograph data between traditional healthcare information systems and mobile healthcare information systems? (2) What are the advantages and disadvantages of these data formats or data standards? The scoping review was conducted in four databases in accordance with the JBI methodology for scoping reviews, and in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). A total of 4018 studies were identified of which 30 studies met the inclusion criteria. Based on our findings, we identify four standards and nine formats for capturing and storing streaming ECG data in mobile health applications. The standards used were HL7, SCP-ECG, x73-PHD, and PDF/A. Formats include CSV, PDF-ECG, and seven XML-based formats. These are ECG-XML, HL7-XML, mPCG-XML, mECGML, JSON, SaECG, and CDA R2.

Tratamiento endovascular a malformación aneurismática de la Vena de Galeno / Endovascular treatment of aneurysmal malformation of the Vein of Galen

Gestante de 19 años sin antecedentes de embarazos previos, presenta a las 27 semanas en ecografía del segundo trimestre hallazgo sugestivo en el feto de MAVG; a las 38 semanas se realiza parto por cesárea sin complicaciones, se planificó angiografía cerebral con embolización. Se abordó por la arteria femoral derecha utilizando lavado heparinizado continuo y sistema de navegación coaxial se estudió la MAVG de tipo mural, se canalizo de forma selectiva a las arterias coroideas postero medial y postero lateral derecha y a la arteria coroidea posteromedial izquierda y se embolizó bajo control radiológico utilizando espirales de coils y líquido embolizante Onix. Control inmediato mostro cierre completo de conexiones fistulosas y preservación de ramas sanas.

A 19-year-old pregnant woman with no history of previous pregnancies, presented at 27 weeks in a second-trimester ultrasound suggestive finding in the fetus of MAVG; At 38 weeks, cesarean delivery was performed without complications, cerebral angiography with embolization was planned. It was approached through the right femoral artery using continuous heparinized lavage and a coaxial navigation system. The mural-type AVM was studied, it was selectively channeled to the right posteromedial and posterolateral choroidal arteries and to the left posteromedial choroidal artery and it was embolized under control. radiological using coil spirals and Onix embolizing liquid. Immediate control showed complete closure of fistulous connections and preservation of healthy branches.

Fabricating a Portable ECG Device Using AD823X Analog Front-End Microchips and Open-Source Development Validation.

Relevant to mobile health, the design of a portable electrocardiograph (ECG) device using AD823X microchips as the analog front-end is presented. Starting with the evaluation board of the chip, open-source hardware and software components were integrated into a breadboard prototype. This required modifying the microchip with the breadboard-friendly Arduino Nano board in addition to a data logger and a Bluetooth breakout board. The digitized ECG signal can be transmitted by serial cable, via Bluetooth to a PC, or to an Android smartphone system for visualization. The data logging shield provides gigabytes of storage, as the signal is recorded to a microSD card adapter. A menu incorporates the device's several operating modes. Simulation and testing assessed the system stability and performance parameters in terms of not losing any sample data throughout the length of the recording and finding the maximum sampling frequency; and validation determined and resolved problems that arose in open-source development. Ultimately, a custom printed circuit board was produced requiring advanced manufacturing options of 2.5 mils trace widths for the small package components. The fabricated device did not degrade the AD823X noise performance, and an ECG waveform with negligible distortion was obtained. The maximum number of samples/second was 2380 Hz in serial cable transmission, whereas in microSD recording mode, a continuous ECG signal for up to 36 h at 500 Hz was verified. A low-cost, high-quality portable ECG for long-term monitoring prototype that reasonably complies with electrical safety regulations and medical equipment design was realized.
