Using Nominal Group Technique to Identify Key Ethical Concerns Regarding Hearing Aids With Machine Learning
Authors: Naudé Alida , Bornman Juan 
Published: November 2021

Purpose:
Machine learning (ML) in new-generation hearing aid technology presents a beneficial opportunity for development in audiology. It is, however, important to balance new applications against the audiologist's professional ethics to protect the client from any harm. This study aimed to identify the key ethical concerns related to the latest digital hearing aid technology that incorporates ML that could potentially impact the client and/or the audiologist.

Method:
A nominal group technique was conducted with the audiologist to generate and prioritize a list of key ethical concerns related to human data interaction, with specific focus on hearing aids.

Results:
Five categories were identified in relation to the potential impact on the client: (a) privacy and confidentiality, (b) relationship and trust, (c) nonmaleficence, (d) informed decision making, and (e) financial gain. An additional five categories were identified in relation to the potential impact on the audiologist: (a) privacy and confidentiality, (b) professional responsibility, (c) relationship and trust, (d) financial gain, and (e) trust technology. Privacy and confidentiality were ranked as the highest priority that should be considered when supplying clients with the latest hearing aid technology.

Conclusions:
Hearing aid technology has evolved considerably, and audiologists need to keep abreast of and master the general technological developments and the associated ethical challenges that may arise. Discussions on the ethics related to ML and hearing aid fittings will help identify the key ethical concerns involved and, thereby, enhance the ethical sensitivity of the profession.
Beyond Services in the United States of America: Fulbright U.S. Scholar Experience in Vietnam
Authors: Lee Sue Ann S. 
Published: November 2021

Purpose:
This article addresses my experience as a speech-language pathologist in a cultural exchange and global outreach program in Vietnam. The importance and various types of cultural exchange and global outreach programs available through the U.S. Department of State, the current status of educational speech-language pathology programs in Vietnam, and a brief introduction of the country as well as its unique cultural characteristics are also discussed.

Conclusions:
As a Fulbright U.S. scholar, I resided 6 months in Hue, Vietnam, to provide education and consultation services to children who needed speech-language pathology services and their families. The speech pathology profession in Vietnam is significantly underdeveloped. However, several international nongovernmental organizations and foreign universities have assisted Vietnam in developing speech pathology and audiology professions. Among many opportunities to serve the needs of speech pathology and audiology preprofessional education and service delivery in Vietnam, one of the most prestigious opportunities is the Fulbright U.S. Scholar Program. It is my hope that my personal and professional experiences can encourage fellow speech-language pathology and audiology professors and practitioners to apply for a Fulbright scholarship to pursue a rich volunteer experience in a foreign country as well as to improve their cultural competency upon return to their own academic institutions.
Fast‐Tracker 2.0: Improving autonomy of aerial tracking with active vision and human location regression

Published: November 2021

AbstractIn recent years, several progressive studies promote the development of aerial tracking. One of the representative studies is our previous work Fast‐Tracker which is applicable to various challenging tracking scenarios. However, it suffers from two main drawbacks: (1) the oversimplification in target detection by using artificial markers and (2) the contradiction between simultaneous target and environment perception with limited onboard vision. In this study, we upgrade the target detection in Fast‐Tracker to detect and localise a human target based on deep learning and non‐linear regression to solve the former problem. For the latter one, we equip the quadrotor system with 360° active vision on a customised gimbal camera. Furthermore, we improve the tracking trajectory planning in Fast‐Tracker by incorporating an occlusion‐aware mechanism that generates observable tracking trajectories. Comprehensive real‐world tests confirm the proposed system's robustness and real‐time capability. Benchmark comparisons with Fast‐Tracker validate that the proposed system presents better tracking performance even when performing more difficult tracking tasks. The cover image is based on the Original Article Fast‐Tracker 2.0: Improving autonomy of aerial tracking with active vision and human location regression by Can Cui et al., https://doi.org/10.1049/csy2.12033.
Impedance modelling and grid integration stability evaluation of three‐phase virtual synchronous generator

Published: November 2021

AbstractVirtual synchronous generator (VSG), which can behave with analogous characteristics as the conventional synchronous generator (SG) and provide voltage and inertia/damping support, is universally regarded as a grid‐friendly interface. Here, the comprehensive sequence‐impedance model of the VSG is developed by using the harmonic linearization method. To improve the accuracy of impedance model, the influences of the reactive power loop (RPL) and mirror frequency effect (MFE) are discussed and evaluated for the first time. Three different impedance models of the VSG (conventional, considering RPL, and considering both MFE and RPL) are derived and compared in detail. Besides, the synchronous frequency resonance (SFR) issue and grid‐interactive oscillation risk of the VSG are also investigated. The results indicate that the VSG may suffer from power oscillation when the integral coefficient of RPL is too large, but has excellent robustness and stability when connected to weak grid. This feature makes it more appealing in weak grid integration. Finally, the validity of the theoretical analysis is verified by simulations and experiments.

Published: November 2021

AbstractReliable communications are essential to provide intelligent services to connected cars. For operational services, connected vehicles in VANET (Vehicle Ad hoc Networks) regularly transfer large amounts of data related to vehicular safety. Similarly, V2X (Vehicle‐to‐Everything) communications include vehicles exchanging information with each other and with infrastructure that is, Vehicle‐to‐Infrastructure (V2I) and Vehicle‐to‐Vehicle (V2V). This paper has analyzed the performance of IEEE 802.11p and 5G test network in a collaborative manner under realistic conditions. For performance analysis the exchange of safety‐critical road weather and traffic information has been performed to enhance the traffic safety and traffic efficiency in the domain of intelligent transportation system (ITS). The vehicular connectivity is provided in V2V and V2I scenarios by utilizing short‐range IEEE 802.11 standard or cellular approaches, such as the 5G network. Here, we consider combining these technologies in a cooperative manner to exploit jointly their advantages. In this cooperative heterogeneous network, the IEEE 802.11p supports safety‐related pilot use cases while the provision of non‐safety‐related pilot use cases are supported by the 5G test network. The performance analysis revealed that the IEEE 802.11p performs quite reasonably well with restricted mobility in contrast of 5G test network in a collaborative manner to avoid road accidents.

Authors: Guzmán-Calderón Edson , Martinez-Moreno Belen , Casellas Juan A. , Aparicio José Ramón 
Published: November 2021

Abstract
Background and study aims Approximately 11 % of biliary cannulations are considered difficult. The double guidewire (DGW-T) and transpancreatic sphincterotomy (TPS) are two useful techniques when difficult cannulation exists and the main pancreatic duct is unintentionally accessed. We carried out a systematic review and meta-analysis to evaluate the effectiveness and security of both DGW-T and TPS techniques in difficult biliary cannulation.
Methods We conducted a systematic review in different databases, such as PubMed, OVID, Medline, and Cochrane Databases. Were included all RCT which showed a comparison between TPS and DGW in difficult biliary cannulation. Endpoints computed were successful cannulation rate, median cannulation time, and adverse events rate.
Results Four studies were selected (4 RCTs). These studies included 260 patients. The mean age was 64.79 ± 12.99 years. Of the patients, 53.6 % were men and 46.4 % were women. The rate of successful cannulation was 93.3 % in the TPS group and 79.4 % in the DGW-T group (P = 0.420). The rate of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) was lower in patients who had undergone TPS than DGW-T (TPS: 8.9 % vs DGW-T: 22.2 %, P = 0.02). The mean cannulation time was 14.7 ± 9.4 min in the TPS group and 15.1 ± 7.4 min with DGW-T (P = 0.349).
Conclusions TPS and DGW are two useful techniques in patients with difficult cannulation. They both have a high rate of successful cannulation; however, the PEP was higher with DGW-T than with TPS.

Published: November 2021

Abstract
Background and study aims The aim of this study was to introduce EndoConf, a reliable and easy-to-use tool capable of optimizing clinical care in endoscopy by reducing the number of repeat endoscopy procedures, providing continuous on-the-job clinical education, and allowing a smooth transition to the next level of artificial intelligence-supported systems.
Patients and methods We prospectively developed and improved a real-time conference system (EndoConf). EndoConf enables endoscopists to contact on-demand and in real time experienced endoscopists across other sites. After the initial introduction period, we registered all EndoConf-assisted procedures from our unit (Surgical Department of Odense University Hospital) over a 3-month period (Autumn of 2019).
Results Of 84 EndoConf-supported procedures, 58 were eligible for further analysis. Eventually, 38 calls were made, of which only four were technically of low quality (10.5 %) while three were not answered (7.9 %). Of the 35 (92.1 %) completed EndoConf calls; 24 were referred for endoscopic mucosal resection, six were referred for transanal microsurgery preceded by transrectal ultrasonography and three were referred for multidisciplinary conference, whereas in two cases, the lesion was resected during EndoConf.
Conclusions We found the EndoConf system to provide support that could reduce the number of unnecessary repeat endoscopic procedures while at the same time ensuring avoidance of any hazardous attempt at polypectomy.

Published: November 2021

Abstract
Purpose We investigated the diagnostic performance of single photon emission computed tomography (SPECT)/computed tomography (CT) as a combination of functional and anatomic imaging, in patients with unspecified chest wall pain.
Methods Fifty-two patients with unspecified chest wall pain and no history of recent major traumatic events or cardiac disease were included. The number and location of radioactive chest wall lesions were evaluated on both planar images and SPECT/CT. The clinical diagnosis was made based on all of the clinical and imaging data and follow-up information.
Results Chest wall diseases were diagnosed in 42 patients (80.8 %). SPECT/CT showed abnormal findings in 35 (67.3 %) patients with positive predictive value (PPV) of 97.1 %. SPECT/CT revealed 56 % more lesions than planar bone scan (P = 0.002) and most of the abnormal radioactive lesions (94.6 %) showed combined morphological changes on the matched CT component. When comparing between age subgroups (< 60 y vs. ≥ 60 y), the prevalence of chest wall disease and diagnosis rate of fracture was significantly higher in the older age group. On SPECT/CT, the older age group showed higher frequency of having abnormal finding (95.8 % vs. 42.9 %, P < 0.001) and significantly more lesions were detected (a total of 189 vs. 32, P = 0.003).
Conclusion SPECT/CT showed good diagnostic performance and proved to have higher sensitivity, detecting 56 % more lesions than planar bone scan. A negative result could be helpful for excluding pathologic chest wall disease. SPECT/CT might be recommended for integration in to the diagnostic workup in patients with unspecified chest wall pain, especially in patients ≥ 60 y of age, considering the high disease prevalence and the high frequency of positive results.
Prädiktoren für die Inanspruchnahme unterschiedlicher
Leistungen zur Teilhabe am Arbeitsleben: Ein Vergleich von
Integrationsmaßnahmen, Teilqualifizierungen und
Vollausbildungen

Zusammenfassung
Ziel der Studie Leistungen zur Teilhabe am Arbeitsleben sind ein
wesentlicher Bestandteil der rehabilitativen Maßnahmen der gesetzlichen
Rentenversicherung und sind immer dann indiziert, wenn gesundheitsbedingte
Einschränkungen die Erwerbsfähigkeit bedrohen. Es gibt
verschiedene Arten von Leistungen zur Teilhabe am Arbeitsleben, die sich
hinsichtlich Inhaltes, Struktur, Dauer, Betreuungsintensität und Kosten
voneinander unterscheiden. Ziel der Studie war es, Merkmale von Rehabilitanden
zu identifizieren, die die Inanspruchnahme unterschiedlicher Leistungen zur
Teilhabe am Arbeitsleben charakterisieren.
Methodik In die Beobachtungsstudie wurden alle Versicherten der Deutschen
Rentenversicherung Baden-Württemberg mit einbezogen, die in den Jahren
2009 bis 2014 im kooperierenden Berufsförderungswerk eine
Integrationsmaßnahme, eine Teilqualifizierung oder eine Vollausbildung
absolviert hatten. Um Hinweise auf die Prädiktoren der Inanspruchnahme
der 3 unterschiedlichen Leistungen zu erhalten, wurde eine multinomiale
logistische Regression mit der Zielgröße Maßnahmenart
berechnet. Als potenzielle Einflussgrößen wurden
soziodemografische Merkmale sowie verschiedene Parameter, die den Erwerbsstatus
der Rehabilitanden im Vorjahr der Maßnahmen abbilden, in das Modell mit
aufgenommen.
Ergebnisse In die Analysen wurden insgesamt 934 Rehabilitanden einbezogen,
die eine Integrationsmaßnahme (n=443), eine Teilqualifizierung
(n=315) oder eine Vollausbildung (n=176) absolviert haben. Im
finalen logistischen Regressionsmodell erwiesen sich Geschlecht
(p<0,0001), Alter (p<0,0001), Schulabschluss (p=0,0033),
Besitz eines Führerscheins (p<0,0001), Umzugsbereitschaft
(p=0,0012), der Antrag auf Anerkennung einer Schwerbehinderung
(p=0,0404) sowie die Beitragsart im dritten Monat vor
Maßnahmenbeginn (p=0,0020) als signifikante Prädiktoren
für die Inanspruchnahme.
Schlussfolgerung Die umfangreicheren und kostenintensiveren
Vollausbildungen werden im Vergleich zu Integrationsmaßnahmen eher von
jüngeren, männlichen, schulisch höher qualifizierten und
vor der Maßnahme im Erwerbsleben stehenden Rehabilitanden in Anspruch
genommen. Entsprechendes gilt teilweise und mit kleineren Effekten auch
für die Teilqualifizierungen.
Untersuchung von Aktivierungsmustern posturaler Muskulatur durch
Fazilitation über die Hände „Hands Induced
Posture“ (HIP) mittels OEMG- Teil 2: Erarbeitung von
Bewegungsmustern
Authors: Best Stefanie , Anders Christoph , Best Norman 
Published: November 2021

Zusammenfassung
Hintergrund Die sensomotorische Fazilitation über die
Hände ist eine Methode, die mutmaßlich die Rumpfmuskulatur
aktiviert und somit eine Alternative zur Kurzfußtechnik nach Janda
darstellen soll. Nach Reliabilitätsuntersuchungen zur Messmethode soll
hier der Nachweis einer Erhöhung der Muskelaktivität mittels
Oberflächen-EMG (OEMG) erbracht werden.
Methoden Mittels OEMG wurden bei 44 jungen gesunden Probanden das
Aktivierungsverhalten von 15 Muskelpaaren während der Fazilitation im
Vergleich zur Ausgangsstellung geprüft.
Ergebnisse Die Fazilitation über die Hände führte
zu einer Aktivierung der Rumpfmuskulatur, die weitgehend symmetrisch erfolgte
und für die überwiegend eine klinische Relevanz nachweisbar war
(Effektstärken>0,8). Seitensymmetrische Unterschiede im Rahmen
der Händigkeit zeigten ein höheres rechtsseitiges
Aktivitätsniveau. Die weiblichen Studienteilnehmer reagierten im Detail
anders als die männlichen Teilnehmer.
Diskussion Zur Vermeidung einer verstärkten asymmetrischen
sensomotorischen Fazilitation auf Grund der Händigkeit ist eine
therapeutische Kontrolle, zumindest zu Beginn der Behandlung, sinnvoll. Die
beobachteten geschlechtsspezifischen Besonderheiten können derzeit nicht
aufgeklärt werden und erfordern weitere Untersuchungen. Systematische
Untersuchungen zur Seitendominanz in ihrer Auswirkung auf die posturale
Rumpfmuskulatur existieren nicht, dennoch können die beobachteten
generellen Seitenabweichungen der Händigkeit zugeordnet werden.
Schlussfolgerung Die HIP eignet sich zur Fazilitation der Rumpfmuskulatur.
Weitere Untersuchungen an der eigentlichen Zielgruppe, bspw. Rollstuhlfahrer,
sind notwendig um die Aspekte gehandicapter Personen weiter zu erfassen.

Published: November 2021

Abstract
Background Pulmonary toxicity due to chemotherapeutic agents can occur with many established and new drugs. Strong clinical suspicion is important as the clinical presentation is usually with nonspecific symptoms like cough, dyspnea, fever, and pulmonary infiltrates. Timely discontinuation of the offending agent alone can improve the condition.
Methods A prospective observational study on patients receiving chemotherapy at an 800-bedded tertiary care hospital was performed from 2014 to 2016. Consecutive patients on chemotherapy, presenting with nonresolving respiratory symptoms were evaluated with contrast-enhanced computerized tomography of chest, diffusion lung capacity for carbon monoxide (DLCO), fiberoptic bronchoscopy with lavage, and biopsy, after excluding all causes for pulmonary infections. Descriptive data has been depicted.
Results A total of 18 patients were evaluated for persistent symptoms of dry cough, dyspnea, and fever among 624 who received chemotherapy during the study period. Ground-glass opacities on high-resolution CT was the most common imaging finding, others being patchy subpleural consolidation and pleural effusion. Lymphocyte-predominant bronchoalveolar lavage was detected in nine. Eight of the 15 patients who underwent DLCO, had abnormal results. Seven had significant histopathological findings on bronchoscopic lung biopsy, which revealed organizing pneumonia as the most common pattern. Paclitaxel, fluorouracil, gemcitabine, and tyrosine kinase inhibitors were the common culprit drugs. Discontinuation alone of the culprit drug was effective in 15 and 3 needed oral corticosteroids for relief of symptoms. None of the patients died due to the toxicity.
Conclusion An incidence of 2.8% for chemotherapy-induced lung injury was seen in our observational study of 3 years, with parenchymal, interstitial, and pleural involvement due to various chemotherapeutic agents. Oral steroids maybe required in a subset of patients not responding to discontinuation of the culprit agent.
Rete Middle Cerebral Artery Anomaly Presenting with a Large Intracerebral Hemorrhage: A Case Report
Authors: Sahu Chandra Dev , Bhargava Nishant , Sahana Debabrata , Kumar Sanjeev 
Published: November 2021

AbstractRete MCA anomaly is extremely rare and has been seldomly discussed in literature. Embryologically MCA develops by fusion of multiple twigs which form a single channel. If there is failure to fuse a plexiform network of vessels persists known as rete MCA. This web like network of vessels is at high risk of haemorrhagic stroke and therefore for patients presenting incidentally correct diagnosis is paramount. Here we report a case of rete MCA anomaly in a 35-year-old gentle man who presented with a large haemorrhagic stroke in emergency. DSA showed unilateral involvement of proximal MCA, and otherwise normal intra-cranial vasculature. With this report we aim to correctly diagnose this rare condition and avoid misdiagnosis leading to unnecessary treatments.
