Spatial Release From Masking in Bimodal and Bilateral Pediatric Cochlear Implant Recipients
Authors: King Kaylene , Dillon Margaret T. , O'Connell Brendan P. , Brown Kevin D. , Park Lisa R. 
Published: December 2020

Purpose
Traditional clinical measures of cochlear implant (CI) recipient performance may not fully evaluate the benefit of bimodal listening (hearing aid contralateral to a CI). The clinical assessment of spatial release from masking (SRM) may be a sensitive measure of the benefit of listening with bimodal stimulation. This study compared the SRM of pediatric bimodal and bilateral CI listeners using a clinically feasible method, and investigated variables that may contribute to speech recognition performance with spatially separated maskers.

Method

Forty pediatric bimodal (
N
= 20) and bilateral CI (
N
= 20) participants were assessed in their best aided listening condition on sentence recognition in a four-talker masker. Testing was completed with target and masker colocated at 0° azimuth, and with the masker directed at 90° to either ear. SRM was calculated as the difference in performance between the colocated and each 90° condition. A two-way mixed-methods analysis of variance was used to compare performance between groups in the three masker conditions. Multiple regression analyses were conducted to investigate potential predictors for SRM asymmetry including hearing history, unaided thresholds, word recognition, duration of device use, and acoustic bandwidth.

Results
Both groups demonstrated SRM, with significantly better recognition in each 90° condition as compared to the colocated condition. The groups did not differ significantly in SRM. The multiple regression analyses did not reveal any significant predictors of SRM asymmetry.

Conclusions
Bimodal and bilateral CI listeners demonstrated similar amounts of SRM. While no specific variables predicted SRM asymmetry in bimodal listeners, pediatric bimodal and bilateral CI recipients should expect similar amounts of SRM regardless of the side of the masker. SRM asymmetry in pediatric bimodal listeners may signal a need for consideration of a second CI.
Cortical Neurophysiologic Correlates of Auditory Threshold in Adults and Children With Normal Hearing and Auditory Neuropathy Spectrum Disorder
Authors: Cardon Garrett , Sharma Anu 
Published: December 2020

Purpose
Auditory threshold estimation using the auditory brainstem response or auditory steady state response is limited in some populations (e.g., individuals with auditory neuropathy spectrum disorder [ANSD] or those who have difficulty remaining still during testing and cannot tolerate general anesthetic). However, cortical auditory evoked potentials (CAEPs) can be recorded in many such patients and have been employed in threshold approximation. Thus, we studied CAEP estimates of auditory thresholds in participants with normal hearing, sensorineural hearing loss, and ANSD.

Method

We recorded CAEPs at varying intensity levels to speech (i.e., /ba/) and tones (i.e., 1 kHz) to estimate auditory thresholds in normal-hearing adults (
n
= 10) and children (
n
= 10) and case studies of children with sensorineural hearing loss and ANSD.

Results
Results showed a pattern of CAEP amplitude decrease and latency increase as stimulus intensities declined until waveform components disappeared near auditory threshold levels. Overall, CAEP thresholds were within 10 dB HL of behavioral thresholds for both stimuli.

Conclusions
The above findings suggest that CAEPs may be clinically useful in estimating auditory threshold in populations for whom such a method does not currently exist. Physiologic threshold estimation in difficult-to-test clinical populations could lead to earlier intervention and improved outcomes.

Published: December 2020

Adding polypropene (PP) fibre can enhance the mechanical properties of coal gangue ceramsite concrete (CGCC), which is a kind of green concrete for solid waste utilisation. However, there is a lack of data concerning the effects of PP fibre content on the micro‐pore structure characteristics and macro‐mechanical properties of CGCC. This investigation aims at exploring the optimum PP fibre content and establishing the relationship between micro‐pore structure characteristics and macro‐mechanical properties, which provides a reference for optimising the mixture ratio. Based on low‐field nuclear magnetic resonance technology and mechanical strength test, micro‐pore structure characteristics and macro‐mechanical properties of CGCC with different PP fibre content of 0, 0.6, 0.9, and 1.2 kg m−3, respectively, were studied. The results showed that when the fibre content was 0.6kg m−3, the mechanical strength was the highest and the increase of splitting tensile strength was the largest. Moreover, PP fibre can effectively reduce the most probable pore diameter and can transform harmful pores to harmless pores with the optimum content of 0.6 kg m−3. In conclusion, appropriate PP fibre addition has a significantly improving effect on the micro‐pore structure characteristics and macro‐mechanical properties of CGCC.

The study evaluates foreign patients' experience and satisfaction in relation to the health care received in Latvia. By applying the gap model of service evaluation, the study reveals the difference between expected and received service outcome in Latvia, and draws conclusions about the importance of individual and patient experience factors related to the overall patient satisfaction. The study concludes that in all groups of factors matrix proposed in the study: (1) general travel or destination factors; (2) communication factors; (3) factors related to the choice of service and (4) factors related to the choice of health care institution, patients evaluated the perceived health care outcome higher than the expected outcome. The results of the study lead to the conclusion that there is a significant gap in foreign patients' knowledge regarding the possibilities of receiving a high-level health care service in Latvia. The results also reveal the most important determinants of patient experience and related satisfaction.

Authors: Dobrev Ivo , Farahmandi Tahmine Sadat , Huber Alexander M. , Röösli Christof 
Published: December 2020

Zusammenfassung
Hintergrund Es sind unterschiedliche Knochenleitungshörgeräte (KLHG) verfügbar, die auf unterschiedliche Art mit dem Stimulationsort in Kontakt stehen. Ziel dieser Arbeit ist eine experimentelle Evaluation eines neuen transkutanen KLHG, das ohne Anpressdruck an die Haut angekoppelt wird.
Material und Methoden Die Messungen wurden an einem Thiel-konservierten Ganzkopfkadaver durchgeführt. Zur Stimulation zwischen 0,1 und 10 kHz wurde ein Adhear verwendet, das über einen Signalgenerator und Verstärker direkt mit 1Vrms aktiviert wurde. Die Kopplung des KLHG erfolgte am Mastoid über ein Hautpflaster. Die Vibrationen des Schädels wurden am ipsi- und kontralateralen Promontorium und an der ipsi-, top- und kontralateralen Schädeloberfläche mittels 3D-Laser-Doppler-Vibrometers registriert. Insgesamt wurden ~200 Punkte auf der Schädeloberfläche (~15–20 mm Abstand) gemessen. Die Daten wurden mit entsprechenden Messungen verglichen, bei denen ein Baha Power als KLHG verwendet wurde. Dieses wurde am Mastoid über einen 5-Newton-Stahlbügel an die Haut gekoppelt.
Ergebnisse Die ipsi- und kontralateralen promontorialen Vibrationen bei Stimulation mit dem Adhear sind in ihrer frequenzspezifischen Amplitude und Phase wie auch in der Zusammensetzung der Bewegungskomponenten mit der Stimulation mittels Baha Power am Stahlbügel vergleichbar. Ebenso erfährt die Schädeloberfläche unter beiden Ankopplungsarten eine vergleichbare komplexe räumliche Bewegung.
Schlussfolgerungen Obwohl das Adhear ohne Anpressdruck und das Baha Power am Stahlband mit 5N an die Haut über dem Mastoid gekoppelt werden, unterscheiden sich die untersuchten Parameter kaum.

Published: December 2020

Abstract
Background The triangular fibrocartilage complex (TFCC) lesions are frequently implicated as a cause of ulnar wrist pain following impact and loading injuries. The objective of this study was to describe the clinical outcomes following TFCC lesion repair with the arthroscopic outside-in technique.
Description of Technique We inserted a 21-gauge needle with 4–0 nylon loop perpendicular to the injured triangular fibrocartilage (TFC). We held two 4–0 nylon loops with mosquito forceps, drew them once out of the joint through a 4 to 5 portal, and put both sides through each loop. After that, we pulled out the 21-gauge needles and performed outside-in sutures after making a small incision and tying directly over the capsule.
Patients and Methods Twenty-one wrists who underwent arthroscopic capsular repair were included. Arthroscopic findings were evaluated, and we used a distal radioulnar joint (DRUJ) evaluation system to monitor relief of pain, forearm rotation range of motion, and DRUJ stability postoperatively.
Results Simple ulnar avulsion (Palmer 1B, Atzei Class 1) was recognized in ten wrists. A combination of the 1B tear with a horizontal TFC tear was noted in five wrists; and ulnar avulsion extending to the dorsal half of the TFC was identified in six wrists, including complete dorsal avulsion of the TFC from the capsule. There are significantly better results in the cases whose preoperative periods were 15 months or less.
Conclusion The outside-in TFC repair technique produced excellent clinical results for peripheral detachment of the TFC in cases without severe DRUJ instability and with a preoperative period less than 15 months.

Abstract
Machine learning is a method used to create programs that can learn from data or applications. In contrast to ordinary static computer programs, machine learning programs are programs designed to be able to learn on their own. Machine learning technology has been widely applied in various fields, including in chemistry. Currently the introduction of basic chemical objects is a study that has many concepts that are easy for beginners to understand and imagine, such as atomic structure and molecular shape in chemical bonds. So that an alternative learning media is needed in order to improve understanding of the concept of chemical objects interactively. Machine learning technology is expected to provide a more realistic interaction and is an advancement of a promising technological method that can motivate users to engage in a more active learning system.

Abstract
Durability problem is a usual shortcoming of utilizing timber as a construction material. After exposed to the weather in decades, the historic timber building often experienced a severe deterioration process. Amantubillah Palace, as Mempawah Sultanate’s inheritance, also suffers from this process. The repair and replacement action are needed to preserve this legacy from the past. Thus, it is essential to know the remaining service life of the building. The calculations of decay depth were carried out by utilizing the Australian CSIRO model incorporating the parameters which are related to the Indonesian tropical climate. From the calculations, it is obtained that the decaying process will reach the centre of the cross-section in 83 years. It is recommended that repair or replacement action should be taken immediately.

Abstract
Biomass is a renewable energy source derived from plants and is known as green energy. Biomass is a term used for various types of organic matter in solid form that can be used as fuel. Bio Briquette is a solid fuel made from a mixture of biomass. This fuel is an alternative material that was developed in a bulk with relatively short time and is relatively cheaper. The use of briquettes that must be included with the use of a stove or stove which type and size must be adjusted to the needs. To increase the heat efficiency of the existing briquette stoves, this research was carried out using two different types of stove walls, namely cement-filled stoves and glass wool-filled walls. The performance of the stove can be seen from the combustion of biomass briquette fuel against the briquette shape was molded. From the tests that have been carried out, the efficiency of stoves with cement walls is 29.86%, while for stoves with glass wool walls is 40%. Of the three forms of bio briquette (ellipsoidal, cylinder, perforated cylinder) the use of cylindrical bio briquettes is better because the flame on the briquette is longer when compared to other forms.

Published: December 2020

Abstract
The selection of raw materials is the cost-wise strategy for biodiesel to compete with diesel. The raw material used in the second generation of biodiesel production is non-edible oil which contains high free fatty acids (FFA). Palm Fatty Acid Distillate (PFAD); the by-product of crude palm oil (CPO) industry has a high potential as the amount is abundant in Indonesia. The objective of this study is to compare the catalytic activity of esterification reaction using self-synthesized sulphated alumina and a sulphuric acid catalyst against the reduction of FFA. The reaction was carried out in a three-necked flask, at a temperature of 60°C, 7 hours of reaction time and rotation speed of 400 rpm. The results showed that the maximum FFA conversion of PFAD esterification reactions over sulphated alumina was 84%, achieved at methanol to oil ratio of 1.7 (v/v), catalyst to PFAD ratio of 12 % (w/w) and reaction time of 7 hours. Meanwhile, the optimum conditions for PFAD esterification usingsulphuric acid catalyst are methanol to oil volume ratio of 1.5; catalyst to PFAD ratio of 7.4 wt.% and 3 hours of reaction time. 99.34% of FFA conversion was achieved with the homogeneous catalyst.

Abstract
Nanocellulose is made from wood, cotton, cellulose-rich materials, and organisms by mechanical methods or chemical dissolution. Nanocellulosefilms are a flexible substrate with excellent thermal and chemical stability. These excellent properties are useful as electrodes for wearable type devices that replace plastic films. In addition, cellulose is both biodegradable and eco-friendly. Problem is that the cellulose film does not have electrical conductivity. In this study, a nanocelluloseconductive film made of composite carbon nanotubes was produced by a simple spray method. It was investigated whether this conductive film is useful as an electrode for electrochemical measurement.

Published: December 2020

Abstract
One of the techniques to improve the surface hardness of commercially pure titanium is by using plasma nitrocarburizing. This paper presents an equation to predict the surface hardness with the variable of the treatment temperature and process time of plasma nitrocarburizing. Experimental studies were first conducted to collect surface hardness at different elevated temperatures with different process time. The prediction equation was then developed by using Lagrange’s Multivariable Interpolation method. It is found that commercially pure titanium surface hardness can be predicted as a function of time and temperature. This equation is able to predict the surface hardness of the experimental data with high accuracy. The errors of the predicted hardness to the experimental results are less than 1 percent.
Cinematizing the Epic Gaze: Julius Caesar and Pompey in Lucan and in the HBO/BBC Television SeriesRome1
Authors: Novokhatko Anna A. 
Published: December 2020

AbstractIn this article I argue that a gaze-oriented analysis of the representations of the protagonists Caesar and Pompey in Lucan’s epic The Civil War (written 62–65 ce) and in the recent television series Rome (broadcast by HBO, BBC Two and Rai 2 between 2005 and 2007) opens new opportunities both for interpreting Lucan’s text and for comprehending its reception in the television series. Lucan deliberately employs intensive vocabulary and narrative of vision and visuality when his protagonists appear. In Lucan, Caesar and Pompey are represented, zoomed in upon, and put into action in a cinematic way. The manner in which they see and are seen is crucial for their distinctiveness and determine their function in epic. In the television series, these patterns are taken over and reused within the new technical medium.
Finger blood flow after the cold challenge with primary Raynaud’s syndrome: a case report
Authors: Fujii Yuichi , Kishimoto Shinji , Higashi Yukihito 
Published: December 2020

Abstract

Background
Raynaud’s syndrome is a commonly encountered disorder. The relationship between the grade of Raynaud’s phenomenon and severity of vasoconstriction is unclear. Recently, various methods including colour Doppler ultrasonography have been used for assessment of vascularity of the extremities including fingers.

Case summary
A 53-year-old man had a 6-year history of Raynaud’s phenomenon with typical tri-coloured changes proceeding from white, blue to red and slight pain and slight paresthaesia in the fingers of both hands when his fingers were exposed to cold. He was diagnosed with primary Raynaud’s syndrome. After treatment with the calcium channel blocker amlodipine (5 mg once daily), a cold challenge did not induce Raynaud’s phenomenon on the fingers in the present patient. After the cold challenge, colour Doppler ultrasonography showed that vascularity was markedly decreased or was absent, whereas there was little difference in skin colour of the fingers.

Discussion
In Raynaud's phenomenon, vasospasm may occur even if the symptoms are well-controlled with a calcium channel blocker. It is unlikely that clinical symptoms in patients with Raynaud’s syndrome always reflect the severity of vasoconstriction in their fingers.
Left atrial appendage closure device implantation via transhepatic vascular access: a case report
Authors: Zare Pegah , Rechani Luis , Smithson Shaun 
Published: December 2020

Abstract

Background
In patients with non-valvular atrial fibrillation, an estimated 90% of thrombi are located in the left atrial appendage. The WATCHMAN device is a left atrial appendage closure device that is an alternative therapeutic option to reduce the risk of systemic embolization in patients who are intolerant of long-term oral anticoagulation. It can be deployed in the left atrial appendage using a transseptal approach via the femoral vein. Transhepatic venous access is an alternative route for the delivery of the device in a patient with difficult vascular access.

Case summary
An 81-year-old man with persistent non-valvular atrial fibrillation, heart failure with reduced ejection fraction (HFrEF), and diabetes mellitus was deemed a poor candidate for anticoagulation due to recurrent falls and gastrointestinal bleeding. He was selected for a left atrial appendage closure. The initial procedure was aborted after significant resistance to device advancement was encountered in the right femoral vein. Lower extremity venography demonstrated totally occluded femoral and iliac veins bilaterally. The decision was made to implant the device via a transhepatic approach. The procedure had no complications and the patient was discharged on rivaroxaban and aspirin after 3 days.

Discussion
Transhepatic venous access is a viable option in patients with poor femoral access for implantation of the WATCHMAN device. It can be done safely. Knowledge of this procedural alternative can greatly enhance patient care.
Simultaneous single lobar lung transplantation and contralateral lung volume reduction

Published: December 2020

Abstract
Lung transplantation (LTx) and lung volume reduction surgery are established therapies for end-stage chronic obstructive pulmonary disease. Although native lung hyperinflation is a well-known complication of unilateral LTx for chronic obstructive pulmonary disease, the unilateral procedure continues to be performed because of severe shortages of cadaveric donors. As native lung hyperinflation can adversely affect the graft, all possible protection should be provided for patients with one-lobe transplantation. We report an emphysematous juvenile patient who successfully underwent simultaneous living-donor, single-lobe LTx and volume reduction in the contralateral lung.
