Using a Commercially Available App for the Self-Management of Hypertension: Acceptance and Usability Study in Saudi Arabia
Authors: Alessa Tourkiah , S Hawley Mark , Alsulamy Nouf , de Witte Luc 
Published: December 2020

Background
The use of smartphone apps to assist in the self-management of hypertension is becoming increasingly common, but few commercially available apps have the potential to be effective along with adequate security and privacy measures in place. In a previous study, we identified 5 apps that are potentially effective and safe, and based on the preferences of doctors and patients, one (Cora Health) was selected as the most suitable app for use in a Saudi context. However, there is currently no evidence of its usability and acceptance among potential users. Indeed, there has been little research into the usability and acceptance of hypertension apps in general, and less research considers this in the Gulf Region.

Objective
This study aims to evaluate the acceptance and usability of the selected app in the Saudi context.

Methods
This study used a mixed methods approach with 2 studies: a usability test involving patients in a controlled setting performing predefined tasks and a real-world usability study where patients used the app for 4 weeks. In the usability test, participants were asked to think aloud while performing the tasks, and an observer recorded the number of tasks they completed. At the end of the real-world pilot study, participants were interviewed, and the mHealth App Usability Questionnaire was completed. Descriptive statistics were used to analyze quantitative data, and thematic analysis was used to analyze qualitative data.

Results
In total, 10 patients completed study 1. The study found that app usability was moderate and that participants needed some familiarization time before they could use the app proficiently. Some usability issues were revealed, related to app accessibility and navigation, and a few tasks remained uncompleted by most people. A total of 20 patients completed study 2, with a mean age of 51.6 (SD 11.7) years. Study 2 found that the app was generally acceptable and easy to use, with some similar usability issues identified. Participants stressed the importance of practice and training to use it more easily and proficiently. Participants had a good engagement level with 48% retention at the end of study 2, with most participants’ engagement being classed as meaningful. The most recorded data were blood pressure, followed by stress and medication, and the most accessed feature was viewing graphs of data trends.

Conclusions
This study shows that a commercially available app can be usable and acceptable in the self-management of hypertension but also found a considerable number of possibilities for improvement, which needs to be considered in future app development. The results show that there is potential for a commercially available app to be used in large-scale studies of hypertension self-management if suggestions for improvements are addressed.

Актуальность. Метод послеоперационного обез­боливания может влиять на скорость восстановления моторной функции желудочно-кишечного тракта, уровень интраабдоминального давления (ИАД) и способствовать развитию интраабдоминальной гипертензии (ИАГ). Цель: исследовать влияние методов послеоперационного обезболивания на моторную функцию кишечника у детей с перитонитом, осложненным ИАГ. Материалы и методы. 115 детей, которым были проведены оперативные вмешательства по поводу аппендикулярного перитонита, рандомизированы на группы в зависимости от метода послеоперационного обезболивания: «Опиоиды» (n = 36, инфузия морфина), «Лидокаин» (n = 40, инфузия лидокаина), «ЭДА» (n = 39, эпидуральная аналгезия). В зависимости от уровня ИАД и наличия органной дисфункции дети каждой группы были разделены на подгруппы: «без ИАГ» (ИАД < 10 мм рт.ст.), «ИАГ» (ИАД > 10 мм рт.ст.) и «АКС» (абдоминальный компартмент-синдром, ИАГ с органной дисфункцией). Всем детям в послеоперационном периоде проводилось измерение уровня ИАД и оценка скорости восстановления моторной функции желудочно-кишечного тракта. Результаты. Во всех подгруппах группы «ЕДА» время до восстановления перистальтики и первых испражнений и объем остатка по назогастральному зонду были статистически значимо меньшими по сравнению с аналогичными показателями в подгруппах группы «Опиоиды» (Р < 0,05). В подгруппах «ИАГ» и «АКС» группы «ЭДА» также было статистически значимо меньшим время до первых испражнений по сравнению с аналогичными показателями в подгруппах группы «Лидокаин» (Р < 0,05). Статистически значимо меньшими были время до восстановления перистальтики и объем остатка по НГЗ во всех подгруппах группы «Лидокаин» по сравнению с аналогичными показателями группы «Опиоиды» (Р < 0,05). Эпизоды повышения ИАД >10 мм рт.ст. значительно чаще встречались у детей в группе «Опиоиды», чем в группах «Лидокаин» и «ЭДА» (Р < 0,05). Количество эпизодов ИАД > 10 мм рт.ст. имело прямую корреляцию с длительностью времени восстановления перистальтики, но сила такой корреляции была выше в группах «Опиоиды» (rs = 0,78; p = 0,001 и rs = 0,76; p = 0,01) и «Лидокаин» (rs = 0,58; p = 0,008 и rs = 0,95; p = 0,01), чем в группе «ЭДА» (rs = 0,39; p = 0,16 и rs = 0,46, p = 0,43). Выводы. ЭДА является оптимальным методом послеоперационного обезболивания у детей с перитонитом, осложненным ИАГ, который приводит к раннему восстановлению моторной функции ЖКТ и предотвращает дальнейший рост ИАД. Инфузия лидокаина может быть использована как альтернативный метод обезболивания. Системная опиоидная аналгезия оказывает негативное влияние на моторику желудочно-кишечного тракта.
Анализ влияния факторов риска на развитие ранней послеоперационной когнитивной дисфункции после отоларингологических операций в условиях общей анестезии с управляемой гипотензией
Authors: Bondar R.A. 
Published: December 2020

Актуальность. Актуальность проблемы послеоперационной когнитивной дисфункции (ПОКД) обусловлена высокой частотой ее развития (до 30 % у некардиохирургических пациентов), что влечет за собой ряд психосоматических осложнений с потребностью в последующем социальной адаптации таких пациентов, а также существенными экономическими затратами на лечение этих больных. Цель: выявить и проанализировать факторы риска развития ПОКД после отоларингологических оперативных вмешательств в условиях общей анестезии с управляемой гипотонией. Материалы и методы. В исследование включены 127 больных. Кроме общеклинических и лабораторных данных, проведено до- и послеоперационное тестирование нейрокогнитивных функций, исследованы периоперационные показатели состояния антиоксидантной системы и активности свободнорадикального окисления липидов и протеинов, показатели нейронспецифических и воспалительных маркеров в крови. Результаты. Ранняя ПОКД развилась у 31 (24,4 %) пациента. Различия между пациентами с ПОКД и без ПОКД обнаружены (p < 0,05) между такими показателями: возраст, уровень образования, повторная операция, продолжительность операции, анестезии, управляемой интраоперационной гипотензии, глубина интраоперационной седации, результаты оценки когнитивного статуса после операции, уровни продуктов перекисного окисления белков и липидов, нейронспецифической энолазы, интерлейкина-18 в крови, наличие послеоперационной инфекции. Выводы. Установлено, что независимыми факторами риска развития ранней ПОКД после отоларингологических оперативных вмешательств в условиях общей анестезии с управляемой гипотензией в регрессионном анализе являются: пожилой возраст, низкий уровень образования, повторная операция, продолжительность управляемой интраоперационной гипотензии, глубина интраоперационной седации.

Published: December 2020

Teknologi milimeterwave (mmWave) merupakan salah satu teknologi pendukung yang dalam mewujudkan teknologi 5G. Teknologi ini memanfaatkan frekuensi di panjang gelombang antara 10 sampai dengan 1 milimeter. Dalam penerapan teknologi ini dibutuhkan antena yang dapat memenuhi kualifikasi tersebut dan dapat bekerja pada frekuensi 30-300GHz. Salah satu antena yang bisa memenuhi spesifikasi tersebut yaitu Antena Mikrostrip. Namun antena mikrostrip masih memiliki banyak kekurangan, diantaranya bandwidth yang sempit dan gain yang rendah. Oleh karena itu, pada penelitian ini, dirancanglah sebuah antena Reflectarray 13x13 Elemen, dibuat dengan menggunakan PCB Roger RT4003C yang bekerja pada frekuensi 38 GHz dengan ketebalan 0.51mm dan nilai kontanta dielektrik sebesar 3,55 dan bersifat high gain. Proses perancangan antena ini menggunakan Software Ansoft High Frequency Structure Simulator (HFSS) v.15.0. Namun, sebelum merancang antena 13x13 elemen, terlebih dahulu hanya merancang dengan satu elemen tunggal kemudian baru dengan 13x13 elemen yang bertujuan untuk mengetahui pengaruh elemen terhadap nilai Gain dan faktor refleksinya. Berdasarkan hasil simulasi dan pengukuran menunjukan bahwa antena dapat bekerja pada frekuensi 38 GHz dengan gain sebesar 23,67 dBi dan hasil polaradiasi yaitu Unidurectional yang hanya memancarkan kesatu arah tertentu yaitu pada sudut 0o.

Resumo: Esse artigo tem como objetivo analisar a relação entre o lixo e alimentação, tendo em vista como o lixo vem se produzindo paralelamente aos processos de mudança que incidem sobre a alimentação, sua produção, distribuição, consumo e o descarte de alimentos. Ocorre que esses processos de transformação assumiu, ao longo do tempo, características diversas, em decorrência das inovações tecnológicas, industrialização e do concomitante processo de globalização e modernização que vem se fazendo, em especial a partir do século XIX, na medida em que a alimentação deixa de ser localizada e que novos processos de distribuição e consumo se estabelecem, produzindo grandes alterações em relação aos processos anteriores. Sendo assim deseja-se saber quais as mudanças que essas alterações promovem no sistema alimentar e no seu consumo e como irão repercutir na maneira de produzir, armazenar e descartar o lixo.Palavras-chave: Alimentação. Indústria alimentar. Consumo. Lixo GARBAGE AND FOOD Abstract: This article aims to analyze the relationship between garbage and food, in view of how garbage has been taking place in parallel with the change processes that affect food, its production, distribution, consumption and the disposal of food. It happens that these transformation processes took on, over time, different characteristics, due to technological innovations, industrialization and the concomitant process of globalization and modernization that has been taking place, especially since the 19th century, as food ceases to be localized and that new processes of distribution and consumption are established, producing major changes in relation to previous processes. Therefore, we want to know what changes these changes promote in the food system and its consumption and how they will impact the way of producing, storing and disposing of garbage.Keywords: Food.

Low-Latency f0 Estimation for the Finger Plucked Electric Bass Guitar Using the Absolute Difference Function
Authors: Fonseca Christhian Henrique Gomes , Tavares Tiago 
Published: December 2020

Audio-to-MIDI conversion can be used to allow digital musical control through an analog instrument. Audio-to-MIDI converters rely on fundamental frequency estimators that are usually restricted to a minimum delay of two fundamental periods. This delay is perceptible for the case of bass notes. In this dissertation, we propose a low-latency fundamental frequency estimation method that relies on specific characteristics of the electric bass guitar. By means of physical modeling and signal acquisition, we show that the assumptions of this method are based on the generalization of all electric basses. We evaluated our method in a dataset with musical notes played by diverse bassists. Results show that our method outperforms the Yin method in low-latency settings, which indicates its suitability for low-latency audio-to-MIDI conversion of the electric bass sound.

OBJECTIVEApproximately 200 million people worldwide use injectable therapies as part of diabetes management. There appears to be a significant gap between insulin injection technique recommendations and injection practice for many. We aimed to develop and validate a novel, brief, self-administered injection technique assessment questionnaire.RESEARCH DESIGN AND METHODSAn iterative codesign process was conducted. Focus groups and interviews with adults (or parents of children) with type 1 or type 2 diabetes and health care providers (HCPs) elicited views and refined the tool for broader distribution to the target audience. Questions addressed ease of understanding; relevance; included items and potential missing questions; feelings about diabetes; and any discomfort or judgment felt when completing the tool. A user guide was developed with cognitive interviewing performed to ensure relevance, acceptability, readability, and understanding. Statistical analyses included propensity score matching to identify a subset of the Worldwide Injection Technique Questionnaire with similar characteristics. Boruta feature selection, Cramér’s V, and multiple correspondence analysis were conducted.RESULTSHCPs and 16 people with diabetes participated in the initial focus groups and interviews. Questions were reported as clinically relevant, simple to complete, “about the right length,” relevant, and easy to understand. A total of 267 participants completed the survey reviewing the questionnaire. A further 16 participants underwent cognitive interviews. The complete resource was then reviewed by another 23 people with diabetes as a final check for completeness and usability. Statistical analyses demonstrated high validity and reliability.CONCLUSIONThis novel resource is clinically relevant, acceptable, and easy to use as both a clinical tool and a self-assessment tool for people using injectable therapies for diabetes.

Sustainable Finance: Customer Loyalty or green environment?
Authors: Ilma Muhammad Akbar 
Published: December 2020

Abstract: The purpose of this research is to see how the Indonesian bankers in response to OJK roadmap (Financial Services Authority) about sustainable finance. Sustainable financing has several interpretations that are understood differently by every banker. Sustainable finance that explain by OJK is financing for eco-friendly product such as forestry and peat land, energy and transportation, and agricultural. Banks encourage to have healthy or green lifestyle in bank such as drink in a tumbler compared to plastic glass or bottle. On the other hand bank also encourage their marketing directorate to choose potential customer which have a good product and high profitability. The good relationship with customer can made customer loyal to the bank and their business with bank will sustain. The method used in this research is qualitative by in-depth interview on 10 bankers who work in 10 largest banks in Indonesia. We are choosing team leader of credit marketing in each bank, as we already known that marketing is the main profit generator in banks and the person who is directly meet the customer, not only existing customer but also new customer. Consideration of choosing potential customer is marketing responsible. They are made some assessment to the client which is suitable with banks aims. The results in this study indicate that the roadmap that has been launched by OJK has not been in line with marketing employees as there is some information that has not reached the bankers. As some of them still thinking a good relationship with customer will make bank business sustainable. Moreover, in their view of sustainable finance is not only focused on the financing for environmentally friendly efforts, but must be on the view of a good long-term relationship between the bank and its creditors in order to get mutual reciprocal relationship.

Published: December 2020

Nosso trabalho se insere na esteira de contribuições acerca do crescimento dos fluxos migratórios de estrangeiros no Brasil e seus processos de migração e de aprendizagem do Português Brasileiro como Língua Adicional. Famílias estrangeiras chegam ao Brasil e, além de se adaptarem ao novo contexto social, precisam se estabelecer em vários aspectos, sendo que um deles é a garantia de continuidade da educação de seus filhos. Devido à escassez de materiais didáticos voltados para a avaliação do desenvolvimento linguístico de crianças migrantes bilíngues, o presente trabalho tem como objetivo a apresentação e a descrição do processo de elaboração de um guia-avaliativo para este público. Tal motivação ocorreu após uma entrevista com mães de duas nacionalidades distintas sobre suas considerações em relação ao ingresso de seus filhos em escolas brasileiras. Visando atender o objetivo, baseamos as orientações do guia-avaliativo em materiais de avaliação para o contexto bilíngue. Como próximo passo, nos baseamos no guia elaborado por McLaughlin et al (1995) para construir uma versão, em português, das orientações acerca da avaliação de crianças bilíngues. Nesta adaptação, foi considerado o contexto social das instituições brasileiras para que o guia fosse apropriado a esta realidade. Como resultado, foi obtido um guia prático para a avaliação do desenvolvimento linguístico de crianças estrangeiras bilíngues no Brasil. O guia é composto por cinco etapas a serem seguidas pelos avaliadores das escolas e propõe, ao final, medidas estratégicas que auxiliem no desenvolvimento das línguas, tanto materna quanto adicional, dessas crianças.

Published: December 2020

Objectives:
This study is aimed to evaluate the cytotoxic action of two homoeopathic medicines that are derived from Viscum album (VA) extract.

Materials and Methods:
An osteosarcoma cell line was cultured in the presence of two homoeopathic VA preparations (VAD3 and VAD30) and cell viability was evaluated using MTT assay. The cell line U-2 OS was plated in two 96-well plates for 24 h with culture medium at 37 5°C and 5% CO2. Subsequently, this medium was replaced by another one containing VAD3 and VAD30 separately in concentrations ranging from 10 to 100 μL/mL, as well as a control group (culture medium only). These plates were kept in culture for 48 h. MTT assay was performed to evaluate the percentage of viable cells. Subsequently, concentrations ranging from 1 to 10 μL/mL were tested. Results were compared to those of the control group and the mean half maximal inhibitory concentration (IC50) was calculated.

Results:
The MTT assay showed that it is possible to reduce 50% of the osteosarcoma cell population with low concentrations of the homeopathic VAD3 and VAD30 with IC50 of 6 62 μL/mL and 5 82 μL/mL, respectively.

Conclusion:
This is a promising result that shows the action of VAD3 and VAD30 in the U-2 OS lineage of osteosarcoma cancer cells. This opens up the possibility of using this medicine in the treatment of these tumours; if not alone, at least in association with other medicines or techniques.
