Self-Reported Hearing Loss Is Associated With Poorer Health Care Access, Delays, and Communication With Providers During the COVID-19 Pandemic: Findings From the Survey of the Health of Wisconsin COVID-19 Community Impact Survey
Authors: Dillard Lauren K. , Nelson-Bakkum Erin R. , Ouayogodé Mariétou H. , Schultz Amy 
Published: September 2023

Purpose:
This article aimed to evaluate associations of self-reported hearing loss with health care access and delays and difficulties communicating with health care providers during the COVID-19 pandemic.

Method:

The COVID-19 Community Impact Survey was administered online to a sample of participants from the population-based Survey of the Health of Wisconsin study cohort in Spring 2021. Hearing loss was defined as self-reported fair or poor hearing. Difficulty with health care access and delays were defined as self-reporting needing but not getting medical care or self-reporting delays in appointments due to COVID-19, respectively. Poor communication with health care providers was defined as self-reported difficulties communicating with health care providers due to wearing a mask during the COVID-19 pandemic. Logistic regression models were used to evaluate associations between hearing loss and the health care outcomes. Results are presented as odds ratios (
OR
s) with 95% confidence intervals (95% CIs). First, models were adjusted for age and sex. Next, models were additionally adjusted for education, race/ethnicity, self-rated health, and number of chronic conditions.

Results:

This study included 1,582 participants (62.3% women; 11.9% non-White; age range: 18–75+ years). The number of participants with hearing loss was 196 (12.4%). After multivariable adjustment, self-reported hearing loss was associated with poorer health care access (
OR
= 2.41, 95% CI [1.62, 3.59]), health care delays (
OR
= 1.93, 95% CI [1.37, 2.71]), and increased difficulty communicating with health care providers wearing face masks (
OR
= 3.31, 95% CI [2.15, 5.08]) during the COVID-19 pandemic.

Conclusions:
The impacts of the COVID-19 pandemic on difficulties accessing and using health care are likely exacerbated for individuals with hearing loss. There is a need for interventions that will optimize health care experiences for individuals with hearing loss, particularly when face masks and/or telecommunications are used to provide health care services.
3D metal printed slot antenna array with high gain and enhanced bandwidth using triple‐mode sine corrugated cavity resonator
Authors: Rao Jiayu , Nai Kenneth , Vaitukaitis Povilas , Li Yuepei , Hong Jiasheng 
Published: September 2023

AbstractThis letter proposes a class of sine corrugated cavity resonators (SCCR). The SCCR can present slow‐wave features and provide dual‐mode (TE104 and TE105) wideband responses with reasonable sine period and depth. Based on it, a compact high‐gain bandwidth‐enhanced SCCR slot antenna array is designed. The high gain is obtained with seven radiation slots and the wideband is achieved due to three modes being utilised. The three modes include the modes of TE104 and TE105 of the SCCR and one feed slot mode. Compared with published works, the desired TE104 and TE105 can be obtained straightforwardly based on SCCR. The standard WR62 waveguide is utilised to feed the antenna. For validation, direct metal 3D printing technology is used to fabricate it with aluminium and copper powders as a comparison. Both measured results were discussed and showed a good agreement with the simulated ones.
Output current harmonic analysis and suppression method for PMSM drive system with modular multilevel converter

Published: September 2023

AbstractAiming at the output current distortion problem in the low frequency operation of permanent magnet synchronous motor (PMSM) drive system of modular multilevel converter (MMC), the essential relationship between the output current distortion and the injected components is analyzed in this paper. A current harmonic suppression method combining feedforward and feedback compensation is proposed. Firstly, the feedback control method is applied to transform the MMC three‐phase output current into the dq rotating coordinate system at fundamental frequency ω. The harmonics of the AC terms to be suppressed are filtered out. The dominant fundamental frequency component turned into the DC term is retained. Then combined with feedforward control, the control performance of the system is improved. Secondly, the deadbeat predictive current control is improved by introducing an integral link in it. System disturbances caused by parameter changes can be compensated in real time. The design of the control system is simplified and the static error is reduced. Meanwhile, the system has the advantages of small torque pulsation and fast speed response. Finally, the PMSM drive system model of the 11‐level MMC is built in MATLAB/Simulink. The correctness and effectiveness of the proposed suppression method are verified.
ED-2: A cold but not so narrow stellar stream crossing the solar neighbourhood
Authors: Balbinot E. , Helmi A. , Callingham T. , Matsuno T. , Dodd E. , Ruiz-Lara T. 
Published: September 2023

Context. ED-2 is a stellar stream identified as a compact group in integrals-of-motion space in a local sample of halo stars from the third Gaia data release.
Aims. We investigate its nature and possible association with known halo substructures.
Methods. We explored the current properties of ED-2 members in phase-space and also analysed the expected distribution via orbit integration. In addition, we studied the metallicity of ED-2 using APOGEE DR17 and LAMOST DR8 (and re-calibrated DR3).
Results. ED-2 forms a compact group in the x − z (or R − z) plane, showing a pancake-like structure as it crosses the solar neighbourhood. Dynamically, it is most similar to the globular clusters NGC 3201 and NGC 6101 and to the stellar streams Ylgr and Phlegethon. However, its orbit is sufficiently different for none of these objects to likely be the ED-2 progenitor. We also find ED-2 to be quite metal poor: all of its stars have [Fe/H]≤ − 2.42, with a median [Fe/H] = −2.60−0.21+0.20. At this low metallicity, it is unlikely that ED-2 stems from any known globular cluster. Instead, ED-2 seems to be in a similar category as the recently discovered Phoenix and C-19 stellar streams. We find that ED-2 members are scattered across the whole sky, which is due to its current orbital phase. We predict that as this object moves to its next apocentre, it will acquire an on-sky morphology that is similar to that of cold stellar streams. Finally, because ED-2 is nearing pericentre, we predict that additional members found below the plane will have high radial velocities of close to ∼500 km s−1 in the present-day direction of the globular cluster NGC 6101.
Forgotten treasures in the HST/FOC UV imaging polarimetric archives of active galactic nuclei
Authors: Barnouin T. , Marin F. , Lopez-Rodriguez E. , Huber L. , Kishimoto M. 
Published: September 2023

Context. Over its 13 yr of operation (1990–2002), the Faint Object Camera (FOC) on board the Hubble Space Telescope (HST) observed 26 individual active galactic nuclei (AGNs) in ultraviolet (UV) imaging polarimetry. However, not all of the observations have been reduced and analyzed or set within a standardized framework.
Aims. We plan to reduce and analyze the AGN observations that have been neglected in the FOC archives using a consistent, novel, and open-access reduction pipeline of our own. We then extend the method to the full AGN sample, thus leading to potential discoveries in the near future.
Methods. We developed a new pipeline in Python that will be able to reduce all the FOC observations in imaging polarimetry in a homogeneous way. Most of the previously published reduced observations are dispersed throughout the literature, with the range of different analyses and approaches making it difficult to fully interpret the FOC AGN sample. By standardizing the method, we have enabled a coherent comparison among the different observational sets.
Results. In this first paper of a series exploring the full HST/FOC AGN sample, we present an exhaustively detailed account of how to properly reduce the observational data. Current progress in cross-correlation functions, convolution kernels, and a sophisticated merging and smoothing of the various polarization filter images, together with precise propagation of errors, has provided state-of-the-art UV polarimetric maps. We compare our new maps to the benchmark AGN case of NGC 1068 and successfully reproduce the main results previously published, while pushing the polarimetric exploration of this AGN futher, thanks to a finer resolution and a higher signal-to-noise ratio (S/N) than previously reported. We also present, for the first time, an optical polarimetric map of the radio-loud AGN IC 5063 and we examine the complex interactions between the AGN outflows and the surrounding interstellar medium (ISM).
Conclusions. Thanks to our newly and standardized reduction pipeline, we were able to explore the full HST/FOC AGN sample, starting with observations that had not been previously published (e.g., IC 5063 here). This pipeline will allow us to make a complete atlas of UV polarimetric images of the 26 unique AGNs observed by the FOC, highlighting the importance and necessity of (imaging) polarimeters for the upcoming new generation of 30-m class telescopes.
Management der rheumatoiden Arthritis beim älteren Patienten
Authors: Bauhammer Jutta 
Published: September 2023

ZUSAMMENFASSUNG46 % der Patienten mit einer rheumatoiden Arthritis (RA) in Deutschland sind 65 Jahre oder älter. Sie erkranken entweder in diesem Alter neu, als Late-onset rheumatoide Arthritis (LORA) bezeichnet, oder bringen eine vorbestehende, ggf. langjährige und fortgeschrittene RA ins Alter mit. Die LORA unterscheidet sich im klinischen und serologischen Bild von der RA im jüngeren Alter. Sie verläuft jedoch mit gleicher Aktivität und dem gleichen Risiko für Gelenkdestruktionen und Folgeschäden und sollte ebenso konsequent nach dem Treat-to-Target-Prinzip behandelt werden. Eine Therapie mit konventionellen oder biologischen DMARD ist bei älteren RA-Patienten wirksam und ausreichend sicher. Der Einsatz der Januskinase-Inhibitoren ist bei Patienten > 65 Jahre nicht oder nur nach Risikoabwägung empfohlen. Da ältere RA-Patienten häufiger komorbid sind, sind Wechselwirkungen mit anderen Medikamenten, des Weiteren Vorerkrankungen und die Nierenfunktion in die Therapieentscheidung zu integrieren. Geriatrische Gesichtspunkte sollten in die Führung der DMARD-Therapie und die nichtmedikamentöse Behandlung einbezogen werden.

ZusammenfassungTibiakopffrakturen stellen mehrheitlich komplexe und chirurgisch anspruchsvolle Gelenkfrakturen dar, die für ein zufriedenstellendes Ergebnis ein umfassendes Verständnis der
Frakturmorphologie, der ligamentären und neurovaskulären Begleitverletzungen sowie der diagnostischen und therapeutischen Optionen erfordern. Hierzu ist ein standardisiertes und strukturiertes
Vorgehen erforderlich. Der Erfolg einer Behandlung von Tibiakopffrakturen liegt zu großen Teilen auch an der interdisziplinären Zusammenarbeit von operativ und konservativ tätigen Behandlern im
ambulanten und stationären Bereich, Physiotherapeuten, Patienten und Leistungserbringern (Krankenkassen, gesetzliche Unfallversicherung, Rentenversicherungsträger). Im Auftrag der Deutschen
Gesellschaft für Orthopädie und Unfallchirurgie e. V. (DGOU), der Deutschen Gesellschaft für Unfallchirurgie (DGU) und der Gesellschaft für Arthroskopie und Gelenkchirurgie (AGA) wurde unter
Federführung des Frakturen-Komitees der Deutschen Kniegesellschaft (DKG) ein leitliniengerechter Behandlungspfad zur Tibiakopffraktur erstellt, der im Rahmen eines Delphi-Prozesses in mehreren
Abstimmungsrunden erarbeitet wurde. Dieser Behandlungspfad soll unter Berücksichtigung der aktuellen Literatur Empfehlungen aussprechen und die wichtigsten Behandlungsschritte der Diagnostik,
Therapie und Nachbehandlung darlegen. Mit dem Ziel einer Konsensbildung wurden zudem 25 Aussagen unter Anwendung der Likert-Skala durch die Autoren in mehreren Befragungsrunden revidiert.
Fallbericht über einen Kliniksuizid durch Asphyxie ohne
Strangulation
Authors: Silge Anna K. , Böcker Felix M. 
Published: September 2023

ZusammenfassungEine Suizidgefährdung bildet häufig den Anlass für eine
stationäre psychiatrische Behandlung. Trotz umfangreicher
Sicherheitsvorkehrungen und therapeutischer Interventionen kann es zu Suiziden
in psychiatrischen Krankenhäusern kommen. Solche sogenannten
Kliniksuizide sind selten, aber gerade deshalb schwerwiegend und
bedürfen der Aufarbeitung im Rahmen der Fehlerkultur. Vorgestellt wird
ein Fall, bei dem ein 91-jähriger suizidaler Patient auf einer offen
geführten Station an einem Sonntagvormittag seine Nase mit Watte und
Zellstoff verstopfte und durch zusätzliche Behinderung der Mundatmung
durch ein Kissen einen Suizid durch Asphyxie beging. Der Fallbericht soll auf
diese außergewöhnliche Suizidmethode aufmerksam machen und auf
die Möglichkeit, dass in einer psychiatrischen Klinik ein Suizid auch
ohne „verbotene“ gefährliche Gegenstände
vollendet werden kann.

Published: September 2023

Abstract
Background This study aimed to assess the vision-related quality of life (VRQol) of patients with age-related macular degeneration (AMD) and to evaluate VRQol according to different types of AMD.
Methods In this small-scale, single-center, prospective investigation, patients with AMD and subjects without any signs of macular disease were asked to complete the NEI-VFQ-39. A total of 159 subjects were included and grouped according to the type of AMD as follows: 40 patients with dry AMD in both eyes (DD), 40 patients with exudative AMD in one eye (DE), 41 patients with exudative AMD in both eyes (EE), and 38 subjects without any signs of macular disease, as a control group (CG).
Results The average age of the participants was 76 ± 7 years, and 44% were male. Most participants were retired (22.4%), and 75% of patients were initially diagnosed by their ophthalmologist. All the AMD groups had significantly worse overall VRQol than the CG. For general vision, near vision, mental health, and role difficulties, all the AMD groups had significantly lower scores than the CG. For distance vision, color vision, peripheral vision, driving difficulties, dependency, and social functioning, only patients in the EE and DE groups had significantly worse scores than the CG. The type of retinal fluid in patients with exudative AMD had no effect on overall VRQol; however, we found that the presence of pigment epithelial detachment could be associated with more role difficulties, such as completing work or working long hours.
Conclusion All types of AMD had a negative effect on vision-related quality of life. This effect was significantly more pronounced in patients with exudative AMD in at least one eye. However, the type of retinal fluid in patients with exudative AMD had no influence on their overall vision-related quality of life.

Sleep: An Exploratory Study
Authors: Stichtenoth Guido , Knottnerus-Meyer Niclas , Helmstetter Jonas , Maass Marco , Herting Egbert 
Published: September 2023

Abstract
Introduction New non-medical monitors are offered for respiration
monitoring of neonates. Epigastric motion during sleep was investigated by means
of a wearable tracker in parallel to clinical monitoring. Cohort: 23
hospitalised neonates ready for discharge.
Methods A 3-axes-accelerometer and -gyroscope was placed in a standard
epigastric position. Between two routine care rounds signals were recorded in
parallel to monitoring of impedance pneumography (IP), ECG and pulse oximetry.
Motion signals vs. time charts were evaluated using 10-min episodes and
semiquantitatively assigned to breathing signal quality, regular breathing,
periodic breathing and confounding artefacts. The results were compared with the
impedance pneumographic data.
Results 26 recordings (mean duration: 210 min/infant) were
conducted without bradycardia or apnea alarm. The gestational age at birth
ranged 28.9 to 41.1 and at recording from 35.6 to 42.3 postmenstrual weeks.
Motion patterns of quiet sleep with regular breathing, periodic breathing and
active sleep with confounding body movements were found. The longitudinal and
transversal gyroscope axes resulted in best signal quality. Periodic breathing
was found in up to 80% of episodes and decreased inversely with
gestational age showing significantly more periodic breathing in preterm
infants. Respiration signals of the gyroscope vs. IP showed a low bias and
highly variating frequencies.
Conclusions Standardized motion trackers may detect typical neonatal
breathing and body-motion-patterns, that could help to classify neonatal sleep.
Respiratory rates can only be determined during quiet sleep.
Impact of Phylogenetically Diverse Bacterial Endophytes of Bergenia pacumbis on Bergenin Production in the Plant Cell Suspension Cultures
Authors: Wawrosch Christoph , Oberhofer Martina , Steinbrecher Stefan , Zotchev Sergey B. 
Published: September 2023

AbstractPlant in vitro cultures are potential sources for secondary metabolites. However, low productivity is often a major drawback for industrial application. Elicitation is an important strategy to improve product formation in vitro. In this context, endophytes are of special interest as biotic elicitors due to their possible interaction with the metabolism of the host plant. A total of 128 bacterial endophytes were isolated from the medicinal plant Bergenia pacumbis and taxonomically classified using 16S rRNA gene sequencing. Five strains belonging to different genera were grown in lysogeny broth and tryptic soy broth medium and cells as well as spent media were used as elicitors in cell suspension cultures of B. pacumbis. Production of the main bioactive compound bergenin was enhanced 3-fold (964 µg/g) after treatment with cells of Moraxella sp. or spent tryptic soy broth medium of Micrococcus sp. These results indicate that elicitation
of plant cell suspension cultures with endophytic bacteria is a promising strategy for enhancing the production of desired plant metabolites.

Published: September 2023

Abstract
Background For the small glabrous skin defect, Thenar and Hypothenar skin are useful donors and they have been used as a free flap. Because of similar skin characteristics, both flaps have same indications. We will conduct comparative study for the donor morbidity of the Free thenar flap and Hypothenar free flap.
Methods From January 2011 to December 2021, demographic data, characteristics of each flap, and complications using retrospective chart review were obtained. Donor outcomes of the patient, who had been followed up for more than 6 months, were measured using photographic analysis and physical examination. General pain was assessed by Numeric Rating Scale (NRS) score, neuropathic pain was assessed by Douleur Neuropathique 4 Questions (DN4) score, scar appearance was assessed by modified Vancouver Scar Scale (mVSS), and patient satisfaction was assessed on a 3-point scale. Statistical analysis was performed on the outcomes.
Results Out of the 39 survey respondents, 17 patients received Free thenar flaps, and 22 patients received Hypothenar free flaps. Thenar group had higher NRS, DN4, and mVSS (p < 0.05). The average scores for the Thenar and Hypothenar groups were 1.35 and 0.27 for NRS, 2.41 and 0.55 for DN4, and 3.12 and 1.59 for mVSS, respectively. Despite the Hypothenar group showing greater satisfaction on the 3-point scale (1.82) compared with the Thenar group (1.47), the difference was not significant (p = 0.085). Linear regression analysis indicated that flap width did not have a notable impact on the outcome measures, and multiple linear regression analysis revealed no significant interaction between flap width and each of the outcome measures.
Conclusion Despite the limited number of participants, higher donor morbidity in general pain, neuropathic pain, and scar formation was noted in the Thenar free flap compared with the Hypothenar free flap. However, no difference in overall patient satisfaction was found between the two groups.

Published: September 2023

Abstract
Background There are few studies on continuous intercostal nerve block after single operation hole thoracoscopic surgery, that is, two-port thoracoscopic surgery.
Objective To evaluate the analgesic effect of continuous intercostal nerve block after thoracoscopic surgery.
Methods A total of 80 patients who underwent single operation hole thoracoscopic surgery in our hospital between September 2020 and June 2021 were enrolled and divided into two groups. Based on basic analgesia, an intercostal catheter was placed during the operation for continuous intercostal block analgesia after the operation in the experimental group (group A, n = 40). The control group (group B, n = 40) was treated with sufentanil intravenous analgesia after surgery, which is namely “basic analgesia.” The postoperative pain scores, restlessness during the recovery period, effect on reducing opioid use, postoperative chest complications, patient satisfaction, etc., were compared between the two groups.
Results The pain scores of patients in group A were significantly lower compared with those in group B at 12, 24, 36, and 48 hours after surgery (3.325 ± 1.163 vs. 4.550 ± 1.176, 2.650 ± 1.001 vs. 4.000 ± 1.038, 2.325 ± 0.917 vs. 3.700 ± 0.966, and 1.775 ± 1.050 vs. 3.150 ± 1.075, p < 0.001, respectively). Sufentanil consumption in group A was significantly lower than in group B at 48 hours after surgery (98.625 ± 4.158 vs. 106.000 ± 7.228, p < 0.001).
Conclusion Multimodal analgesia is ideal for early pain control after thoracotomy. A continuous intercostal nerve block can effectively reduce postoperative pain in patients.
