ABSTRACT

To prevent the spread of the COVID-19 pandemic, 2019 has seen unprecedented demand for medical equipment and supplies. However, the problem of waste treatment has not yet been given due attention, i.e., the traditional waste treatment process is done independently, and it is not easy to share the necessary information. Especially during the COVID-19 pandemic, the interaction between parties is minimized to limit infections. To evaluate the current system at medical centers, we also refer to the traditional waste treatment processes of four hospitals in Can Tho and Ho Chi Minh cities (Vietnam). Almost all hospitals are handled independently, lacking any interaction between the stakeholders. In this article, we propose a decentralized blockchain-based system for automating waste treatment processes for medical equipment and supplies after usage among the relevant parties, named Medical-Waste Chain. It consists of four components: medical equipment and supplies, waste centers, recycling plants, and sorting factories. Medical-Waste Chain integrates blockchain-based Hyperledger Fabric technology with decentralized storage of medical equipment and supply information, and securely shares related data with stakeholders. We present the system design, along with the interactions among the stakeholders, to ensure the minimization of medical waste generation. We evaluate the performance of the proposed solution using system-wide timing and latency analysis based on the Hyperledger Caliper engine. Our system is developed based on the hybrid-blockchain system, so it is fully scalable for both on-chain and off-chain-based extensions. Moreover, the participants do not need to pay any fees to use and upgrade the system. To encourage future use of Medical-Waste Chain, we also share a proof-of-concept on our Github repository.

ABSTRACT

PURPOSE: The aim of this pilot feasibility study was to evaluate the effectiveness of the group VietSpeech SuperSpeech program targeting speech skills and home language maintenance via telepractice. METHOD: In Stage 1, using a case-control design, 30 Vietnamese-English-speaking children were assessed in English and Vietnamese, and parents completed questionnaires about speech and language competency and practices. During Stage 2, children were allocated to intervention (n = 14) or control (n = 16) conditions. COVID-19 restrictions resulted in changes including nonrandom allocation. Online group intervention targeting speech, home language maintenance, and multilingualism as a superpower was delivered 1 hr/week for 8 weeks. For Stage 3, assessments were undertaken approximately 10 weeks after the pre-intervention assessment. RESULTS: Parents in the intervention group significantly increased encouragement of their children to speak Vietnamese. The intervention group significantly increased intelligibility in English. Growth of Vietnamese vocabulary was faster for the control group. There was a moderate effect of intervention for children's perception of being happy talking in Vietnamese and English. There was no significant mean change from pre- to post-intervention compared with the control group for measures of speech sound accuracy in Vietnamese or English, Vietnamese intelligibility, English vocabulary, or hours of Vietnamese spoken each week. CONCLUSIONS: This study presents preliminary evidence that this 8-hr online group program targeting speech skills and home language maintenance had some impact on Vietnamese-Australian children's speech and home language maintenance. Further research involving a randomized trial is warranted.

ABSTRACT

Résumé Objectifs Durant l’épidémie de Covid-19, l’accès au diagnostic et aux soins des pathologies relevant de l’audiologie médicale a régressé en France, posant un risque de perte de chance pour le patient. Ce guide de conseils de bonne pratique vise à répertorier les solutions techniques existantes permettant d’examiner à distance le patient présentant une plainte en audiologie et à décrire leurs intérêts et, le cas échéant, leurs limites. Méthodes Les conseils ont pu être élaborés à la fois à partir de l’expérience clinique des experts médicaux ayant participé à la rédaction du guide, et d’une revue extensive de la littérature portant sur les recommandations de pratique clinique en télé-audiologie. Les solutions de télé-audiométrie ont été recensées sur la base d’une requête par moteur de recherche effectuée en avril 2020, avant vérification de leur disponibilité sur le marché européen. Résultats Des solutions de vidéo-otoscopie permettent la télé-transmission d’images compatibles avec un diagnostic de qualité soit en se connectant via internet à une plate-forme de télé-soin, soit via un smartphone ou une tablette utilisant un système d’exploitation iOS ou Androïd. Selon les mêmes modalités, il est possible de réaliser à distance un examen audiométrique tonal dans les règles de l’art, une audiométrie vocale dans le silence ou dans le bruit ainsi que des explorations fonctionnelles objectives de l’audition. Les examens cliniques et paracliniques peuvent être consultés par le médecin de façon différée pour être interprétés (télé-audiologie asynchrone). Ils peuvent aussi être réalisés en temps réel chez un patient, à tout âge de la vie, à condition qu’un aidant puisse être présent durant l’installation des transducteurs ou la réalisation de l’acoumétrie (télé-audiologie synchrone). Les solutions de téléaudiologie trouvent également une application dans la formation à distance des futurs professionnels de santé engagés dans la prise en charge des pathologies de l’audition. Conclusion Dans la législation française, la télé-otoscopie est un acte médical qui relève soit de la télé-expertise (avis asynchrone) soit d’un acte de téléconsultation (avis synchrone). L’évaluation subjective et objective de la fonction auditive du patient est aujourd’hui possible à distance à condition de respecter les précautions listées.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has had a profound worldwide impact. Vietnam, a lower middle-income country with limited resources, has successfully slowed this pandemic. The objectives of this report are to explore the impact of the COVID-19 pandemic on the research activities of an ongoing hypertension trial using a storytelling intervention in Vietnam. METHODS: Data were collected in a mixed-methods study among 86 patients and 10 health care workers participating in a clinical trial designed to improve hypertension control. Several questions related to the impact of COVID-19 on patient's daily activities and adherence to the study interventions were included in the follow-up visits. A focus group discussion was conducted among health care workers to discuss the impact of COVID-19 on research related activities. RESULTS: Fewer patients in the intervention group reported that they faced difficulties in adhering to prescribed study interventions, wanted to receive a call from a dedicated hotline, or have a visit from a community health worker as compared with those in the comparison group. Most study patients are willing to participate in future health research studies. When asked about the potential use of mobile phones in health research studies, fewer patients in the intervention group felt comfortable using a mobile phone for the delivery of intervention and interviews compared with those in the comparison condition. Community health workers shared that they visited patient's homes more often than previously due to the pandemic and health care workers had to perform more virus containment activities without a corresponding increase in ancillary staff. CONCLUSIONS: Both patients and health care workers in Vietnam faced difficulties in adhering to recommended trial interventions and procedures. Multiple approaches for intervention delivery and data collection are needed to overcome these difficulties during future health crises and enhance the implementation of future research studies.

ABSTRACT

OBJECTIVES: In the context of the SARS-CoV-2 pandemic, patients may have been dissuaded from seeking consultation, thus exposing themselves to a risk of loss of chance. This guide aims to define how teleconsultation can assist in assessing vertiginous adults or children, and to gather the information needed to provide quick medical care. METHODS: These recommendations rely on the authors' experience as well as on literature. A survey on otoneurologic approach via telemedicine has been conducted based on a literature search until March 2020. RESULTS: The first clinical assessment of the vertiginous patient via teleconsultation can only be successful if the following conditions are met: initial contact to verify the feasibility of the assessment at a distance, the presence of a caregiver in order to assist the patient, the possibility of making video recordings. Medical history via telemedicine, as in a face-to-face assessment, allows to assess the characteristics, duration, frequency, and potential triggering factors of the vertigo, in both children and adults. During teleconsultation, the following tests can be carried out: oculomotricity evaluation, assessment of balance, simple neurological tests, checking for positional vertigo/nystagmus and, eventually to perform canalith-repositioning procedures. In children, the following should be searched for: history of hearing or visual impairment, a context of fever or trauma, otorrhea, signs of meningeal irritation. CONCLUSION: The neurotologic telemedicine relies on the accuracy of the clinical assessment, which is based on history taking and a few simple tests, encouraging the development of a decision-making algorithm adapted for teleconsultation. However, the latter has its limitations during an emergency examination of a new patient presenting vertigo, and, at least in some cases, cannot replace a face-to-face consultation. Teleconsultation is often adapted for follow-up consultations of previously selected vertiginous patients during face-to-face assessment.

ABSTRACT

In the context of the SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2) pandemic, the medical system has been subjected to many changes. Face-to-face treatments have been suspended for a period of time. After the lockdown, dentists have to be aware of the modalities to protect themselves and their patients in order not to get infected. Dental practitioners are potentially exposed to a high degree of contamination with SARS-CoV-2 while performing dental procedures that produce aerosols. It should also be noted that the airways, namely the oral cavity and nostrils, are the access pathways for SARS-CoV-2. In order to protect themselves and their patients, they have to use full personal protective equipment. Relevant data regarding this pandemic are under evaluation and are still under test. In this article, we made a synthesis about the way in which SARS-CoV-2 spreads, how to diagnose a novel corona virus infection, what the possible treatments are, and which protective personal equipment we can use to stop its spreading.

ABSTRACT

OBJECTIVES: Access to diagnosis and treatments for auditory disorders and related pathologies has regressed in France during the COVID-19 pandemic, posing a risk to the patient's chance of recovery. This best practice recommendations guide aims to list the existing technological solutions for the remote examination of a patient with hearing complaint, and to outline their benefits and, where applicable, their limitations. METHODS: The recommendations were developed both from the clinical experience of the medical experts who drafted the guide, and from an extensive review of the literature dealing with clinical practice recommendations for tele-audiology. Tele-audiometry solutions were identified on the basis of a search engine query carried out in April 2020, prior to verification of their availability on the European market. RESULTS: Video otoscopy solutions allow for the teletransmission of images compatible with a high-quality diagnosis, either by connecting via internet to a tele-health platform or using a smartphone or a tablet with an iOS or Android operating system. Using the same telecommunication methods, it is possible to remotely conduct a pure-tone audiometry test in accordance with standard practice, a speech-in-quiet or a speech-in-noise audiometry test, as well as objective measures of hearing. Clinical and paraclinical examinations can be accessed by the physician to be interpreted on a deferred basis (asynchronous tele-audiology). Examinations can also be conducted in real time in a patient, at any age of life, as long as a caregiver can be present during the installation of the transducers or the acoumetry. Tele-audiology solutions also find application in the remote training of future healthcare professionals involved in the management of deafness and hearing impairment. CONCLUSION: Under French law, tele-otoscopy is a medical procedure that is either a tele-expertise (asynchronous adive) or a teleconsultation act (synchronous advice). Subjective and objective evaluation of the patient's hearing functions can be done remotely provided that the listed precautions are respected.
