Qualitätsgesicherte Übersetzung des Wijma Delivery Expectancy Questionnaire (W-DEQ_A) ins Deutsche
Authors: Mattern Elke , Ayerle Gertrud M. 
Published: September 2021

ZUSAMMENFASSUNG
Einleitung Der „Delivery Expectancy Questionnaire“ von Claas Wijma et al. (W-DEQ_A), der in der Schwangerschaft international am häufigsten zur Bestimmung von großer Angst vor der Geburt eingesetzt wird, lag bisher nicht in der deutschen Sprache vor. Angst vor der Geburt wird in europäischen Ländern, Canada, Australien und den USA mit einer Prävalenz von 6,3% bis 14,8% angegeben. Insbesondere bei Frauen mit Angst vor der Geburt sind die Risiken für eine Präeklampsie, intrauterine Wachstumsretardierung und Kaiserschnitte erhöht.
Methode Eine von Claas Wijma autorisierte englische Fassung des W-DEQ_A wurde entsprechend der Richtlinie von Ohrbach et al. (INfORM) sprachlich übersetzt und kulturell adaptiert. Die Inhaltsvalidität wurde statistisch durch die Scale-Content Validity Index/Average Methode (S-CVI/Ave) bestimmt.
Ergebnisse Die einer unabhängigen Begutachtung unterzogenen übersetzten Textteile des W-DEQ_A belegten die sprachliche und kulturelle Validität. Eine einleitende Frage und drei Items mussten erneut übersetzt werden. Darüber hinaus war eine Änderung der Formulierung bei drei weiteren Items notwendig, um eine kulturelle Äquivalenz zu erreichen. Die errechnete Inhaltsvalidität ergab einen „exzellenten“ S-CVI/Ave von 0,91.
Schlussfolgerung Als Fragebogen zur Selbsteinschätzung mit dem Titel „Gedanken und Gefühle schwangerer Frauen im Hinblick auf die bevorstehende Geburt“ liegt der W-DEQ_A nun in Deutsch vor. In Form einer digitalen Gesundheits-App könnte der Fragebogen verschrieben und das Ergebnis direkt in die elektronische Patientenakte übernommen werden.
Exercise Dose and Aerobic Fitness Response in Alzheimerʼs Dementia:
Findings from the FIT-AD Trial
Authors: Salisbury Dereck , Mathiason Michelle A. , Yu Fang 
Published: September 2021

AbstractThe purpose of this study was to examine the effects of a 6-month cycling aerobic
exercise intervention on cardiorespiratory fitness and the dose-response
relationship in community-dwelling older adults with mild-to-moderate
Alzheimerʼs dementia. The FIT-AD trial was a single blind, 2-parallel group,
pilot randomized controlled trial. The aerobic exercise group participated in a
6-month, thrice weekly, moderate-vigorous intensity cycling intervention while
control group performed stretching. Cardiorespiratory fitness was evaluated by
peak oxygen consumption from cardiopulmonary exercise test and peak walking
distance from the shuttle walk test and 6-minute walk test. Aerobic exercise
dose was calculated using the novel heart rate physical activity score. The
aerobic exercise group significantly increased peak oxygen consumption
(1.28 ml/kg/min; p=0.03) in subgroup who
achieved maximal criteria on cardiopulmonary exercise test. Changes in peak
oxygen consumption and peak walking distance on the shuttle walk and 6-minute
walk tests did not significantly differ between aerobic exercise and stretching
groups. Notably, the aerobic exercise dose was strongly and significantly
correlated to change in peak oxygen consumption (r=0.60; n=16;
p=0.01), in subset who met maximal test criteria. Emphasis on exercise
dose is needed in aerobic exercise programs to maximize cardiorespiratory
fitness gains in persons with mild-moderate Alzheimerʼs dementia.

Abstract
Introduction Plantar fasciitis (PF) is a chronic degenerative condition causing marked thickening and fibrosis of the plantar fascia, and collagen necrosis, chondroid metaplasia and calcification. There is little convincing evidence in support of various approaches, including homeopathy, for treating PF. This study was undertaken to examine the efficacy of individualized homeopathic medicines (IHMs) compared with placebo in the treatment of PF.
Methods A double-blind, randomized, placebo-controlled trial was conducted at the outpatient departments of Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, West Bengal, India. Patients were randomized to receive either IHMs or identical-looking placebo in the mutual context of conservative non-medicinal management. The Foot Function Index (FFI) questionnaire, as an outcome measure, was administered at baseline, and every month, up to 3 months. Group differences (unpaired t-tests) and effect sizes (Cohen's d) were calculated on an intention-to-treat sample. The sample was analyzed statistically after adjusting for baseline differences.
Results The target sample size was 128; however, only 75 could be enrolled (IHMs: 37; Placebo: 38). Attrition rate was 9.3% (IHMs: 4, Placebo: 3). Differences between groups in total FFI% score favored IHMs against placebo at all the time points, with large effect sizes: month 1 (mean difference, −10.0; 95% confidence interval [CI], −15.7 to −4.2; p = 0.001; d = 0.8); month 2 (mean difference, −14.3; 95% CI, −20.4 to −8.2; p <0.001; d = 1.1); and month 3 (mean difference, −23.3; 95% CI, −30.5 to −16.2; p <0.001; d = 1.5). Similar significant results were also observed on three FFI sub-scales (pain%, disability%, and activity limitation%). Natrum muriaticum (n = 14; 18.7%) and Rhus toxicodendron and Ruta graveolens (n = 11 each; 14.7%) were the most frequently prescribed medicines. No harms, serious adverse events, or intercurrent illnesses were recorded in either of the groups.
Conclusion IHMs acted significantly better than placebo in the treatment of PF; however, the trial being underpowered, the results should be interpreted as preliminary only. Independent replications are warranted.
Trial registration CTRI/2018/10/016014.

AbstractBackground The impact of the coronavirus disease 2019 (COVID-19) outbreak shut down most conferences. To minimalize the influence, virtual meetings sprang up subsequently. International Microsurgery Club (IMC), as one of the largest professionals-only online microsurgery education groups worldwide, began to host regular weekend webinars during the pandemic to fill the knowledge gap. This study aims to discuss how webinars have fundamentally changed the way knowledge is delivered and exchanged.Methods From February 29, 2020 to March 14, 2021, 103 IMC webinars were reviewed and analyzed in detail to determine the use, benefit, and effect. A comparison between webinars hosted by the different societies was made as well. A questionnaire survey focusing on attendees' behavior, attitude, and using habit about webinars was also made.Results As for the 103 IMC webinar events, the peak participants were 112.3 people in average. The members requesting to join IMC abruptly increased during the pandemic, and the group activity increased dramatically. From the questionnaire (n = 68), the satisfaction level was high (8.88 ± 1.18/10). The respondents were most satisfied with the good quality of the speakers (73.5%). Not only hosts our webinar series but IMC also serves as the platform that welcomes webinars from other societies to share their information. In September 2020, International Microsurgery Webinar League was established via the significant webinar hosts, with more than 300 recorded webinar talks connected successfully.Conclusion As the knowledge revolution driven by COVID-19 will continue, IMC will keep playing an essential role in exploring new and emerging opportunities to improve knowledge dissemination worldwide beyond the space-time boundary.

Published: September 2021

Objective This study aimed to examine the epidemiology of antibiotic exposure and early onset sepsis (EOS) in late preterm and term infants born via cesarean section with rupture of membranes less than 10 minutes.
Study design Retrospective review of 1,187 late preterm and term infants born at Brooke Army Medical Center between January 1, 2012 and August 29, 2019. Subjects were assessed for factors related to antibiotic treatment. Statistical analysis was performed to compare infants treated with antibiotics versus observation.
Result An early blood culture was obtained from 234 (19.7%) infants; 170 (14.3%) were treated with antibiotics. Infants treated with antibiotics were significantly younger (p < 0.0001), smaller (p < 0.0001), more often diagnosed with respiratory distress (p < 0.0001), and were more frequently admitted to the neonatal intensive care unit (p < 0.0001). There were no cases of culture proven EOS.
Conclusion Although this population lacks risk factors for the development of EOS, a significant percentage was treated with antibiotics. This population may benefit from future antibiotic stewardship efforts.

Authors: Birua Gyani J.S. , Tyagi Gaurav , Beniwal Manish , Srinivas Dwarakanath , Rao Shilpa 
Published: September 2021

AbstractParenchymal perianeurysmal cysts are rare. We report a case of 50-year-old woman who presented with persistent headaches and episodes of vomiting for the last 2 months. Magnetic resonance imaging of the brain showed a well-defined solitary cystic lesion with a mural nodule measuring 5.4 × 5.2 × 4.6 cm in the right basifrontal region. The mural nodule was cortically based. It was hypointense on T2-weighted fluid-attenuated inversion recovery and showed intense contrast enhancement with few nonenhancing areas—no evidence of diffusion restriction. The cyst wall was nonenhancing, and magnetic resonance angiogram was unremarkable. Differential diagnoses included intra-axial gliomas such as ganglioglioma and pleomorphic xanthoastrocytoma. Right pterional craniotomy and a transcortical approach were made. Subtotal excision of cyst and clipping of right middle cerebral artery bifurcation thrombosed aneurysm were done. After 6 months of follow-up, patient is stable without any deficits. A parenchymal perianeurysmal cyst is a rare entity; it is crucial to be considered a differential diagnosis in any cystic lesion with the mural nodule.

Published: September 2021

Abstract
Context Alveolar soft part sarcoma (ASPS) is a rare soft tissue tumor most commonly occurring in deep intramuscular plane of lower extremities of adolescents and young adults. It is a highly vascular, slow growing tumor with malignant potential having lung as the most common site of metastases at the time of presentation.
Aims The aim is to review the imaging findings of ASPS and determine characteristic imaging features of this rare tumor.
Materials and Methods Sixteen patients having histopathological diagnosis and preoperative imaging of ASPS attending the dedicated sarcoma clinic at our institute were included in the study. The demographic, clinical, and imaging data were retrieved from the case records and then evaluated for characteristic imaging features which may raise suspicion of ASPS.
Results The patients ranged from 3 to 72 years of age and with a slight male preponderance. Of the eight CECTs evaluated, 62.5% tumors showed well-defined lobulated margins, 87.5% cases showed intense enhancement with presence of feeder vessels. On CEMRI of 10 patients, 70% had well circumscribed lobulated margins with intense enhancement and tortuous flow voids in most of them. All cases showed T2 hyperintense signal. Fourteen of 16 (87.5%) patients had metastatic disease with lung as the most common site (92.8%).
Conclusion ASPS is a rare soft tissue sarcoma seen in children and young adults. Imaging may mimic a vascular malformation due to the presence of tortuous feeders. Misdiagnosis at an early stage may lead to later metastatic presentation of the disease, thus emphasizing the need to suspect it on imaging.
A Triad of Unilateral Renal Dysgenesis with Ipsilateral Seminal Vesical and Ejaculatory Duct Obstruction: An Uncommon Urogenital Congenital Anomaly, Zinner Syndrome—A Case Report
Authors: Gorantla Rajani , Allu Sameera , Rao Ankamma 
Published: September 2021

AbstractZinner syndrome is a rare congenital anomaly of the urogenital system resulting from an in utero insult during the first trimester. This entity comprises a triad of unilateral renal agenesis/dysgenesis with ipsilateral seminal vesical and ejaculatory duct obstruction. This combination of urinary and genital abnormalities occurs because of the closely related embryological origin of these structures from the distal mesonephric (Wolffian) duct. Nearly 200 cases of seminal vesical cysts with ipsilateral renal agenesis have been reported in the literature. The affected person generally presents in early adulthood when the reproductive activity commences. In this report, we present a case of a 22-year-old male with complaints of painful ejaculation.
A simple and efficient passive vibration isolation system for large loads in closed-cycle cryostats
Authors: Wiens Eugen , Schiller Stephan 
Published: September 2021

We present a system for passive damping of vibrations along three spatial degrees of freedom for cryostats equipped with closed-cycle coolers. The system, designed to isolate a payload of 30 kg, consists of two stages of isolation for vibrations in the vertical direction. The first isolation stage incorporates a trapezoidal beryllium copper cantilever blade. The second stage is attached to the blade via a steel wire and consists of four extension springs with an extended length of 370 mm. At 1.6 K, the stages possess vertical resonance frequencies of 2.1 and 1.3 Hz, respectively. The vertical length of the setup with a cumulative length of 580 mm also acts as a pendulum with a resonance frequency of 0.65 Hz. In the frequency band from 5 to 200 Hz, the frequency-integrated acceleration decreased from 6.7 × 10−3 to 4.3 × 10−5 g along the horizontal direction and from 4.3 × 10−3 to 7.2 × 10−5 g along the vertical direction. This corresponds to a reduction in vibrations by factors of 156 and 60, respectively. Overall, we achieve a simple, robust, and cost-efficient vibration isolation system for upgrading standard-type cryostats.
High-impact innovations for high-salinity membrane desalination
Authors: Dudchenko Alexander V. , Bartholomew Timothy V. , Mauter Meagan S. 
Published: September 2021

Significance
Researchers lack the tools for quantitatively evaluating the impact of their research on technology costs, especially when those technologies comprise multiple components or when the component costs are highly uncertain. We propose a suite of tools to aid in evaluating technology platforms, setting system- and component-level research targets and identifying high-impact innovation trajectories. These tools are applicable to any technology composed of multiple components whose performance or cost will benefit from innovation, but they are especially valuable for membrane systems in which the high interdependence in components amplifies or dampens the effects of innovation in nonintuitive ways.

Significance
Lithium is a key ingredient in batteries, which are integral components of next-generation automobiles, airplanes, grid energy storage, and electronic devices. Unfortunately, lithium extraction from natural sources is laborious, slow, and costly, motivating the search for more efficient isolation techniques. While polymeric membranes could reduce the cost of lithium recovery, current membrane materials lack sufficient lithium-ion selectivity. To address this challenge, we introduce a class of polymeric membranes that incorporate ion binding sites, which significantly increases the transport selectivity of LiCl over NaCl. These studies provide guidelines and practical considerations for incorporating specific interactants into polymers that mediate selective ion transport.

Published: September 2021

Significance
Inspired by biological models, artificial water channels can be used to overcome the permeability/selectivity trade-off of traditional desalination membranes. We demonstrate that rational incorporation of I-quartet artificial water channels in composite polyamide membranes synthesized via interfacial polymerization, provides defect-free biomimetic membranes with intrinsic water-to-salt permeability on the operational brackish-water reverse osmosis (BWRO)/tap water reverse osmosis (TWRO) desalination pressure and medium/low-salinity conditions.

Published: September 2021

Significance
Xylenes are essential feedstocks for manufacturing packaging materials, versatile chemicals, industrial solvents, etc. The purification of xylene isomers is one of the most important yet energy-intensive organic mixture separations in the chemical industry. We achieved the separation of xylene isomers using carbon molecular sieve (CMS) membranes derived from a spirobifluorene-based polymer of intrinsic microporosity (PIM-SBF), which could potentially reduce the energy consumption, carbon emissions, and equipment footprint. CMS membranes are solvent- and temperature-resistant materials that can withstand high transmembrane pressures when fabricated into the form of hollow fibers. The new CMS membrane produced here shows competitive performance with state-of-the-art zeolites under high xylene loadings, and its development has provided fundamental insight and guidance into the manipulation of CMS pore structure.
Tropical climate influences affects, sensation of fatigue and environmental perceptions (El clima tropical influye sobre los afectos, la sensación de fatiga y las percepciones del medio ambiente)
Authors: Robin Nicolas , Sinnapah Stéphane , Hue Olivier , Coudevylle Guillaume R. 
Published: September 2021

The current experimental study evaluated how a tropical climate (i.e., wet and hot environment) influences positive and negative affects, sensation of fatigue and environmental perceptions (i.e., comfort and thermal sensations). A convenience sampling of students (30 females and 30 males, Mage = 21.94 years, age range: 19–28 years) who lived all the year in the French West Indies performed two conditions in Tropical Climate (TC) and in Neutral Climate (NC), counterbalanced. During each climate condition, they completed the Positive and Negative Affect Schedule and a questionnaire evaluating feeling of fatigue, thermal and comfort sensations. This original study revealed that TC reduces positive affect (PA) scores, whereas no significant statistical difference was revealed for negative affect (NA). In addition, participants revealed lower thermal and comfort sensations and a greater feeling of fatigue in TC than in NC. These results are in line with the suggestion that TC can negatively influence subjective states compared with a temperate climate. Moreover, TC could also have a potential fatigue-enhancing effect and negatively influences comfort sensations. The impact of TC on affective states is discussed.
Strong inelastic scattering of slow electrons by optical near fields of small nanostructures

Published: September 2021

Abstract
The interaction of swift, free-space electrons with confined optical near fields has recently sparked much interest. It enables a new type of photon-induced near-field electron microscopy, mapping local optical near fields around nanoparticles with exquisite spatial and spectral resolution and lies at the heart of quantum state manipulation and attosecond pulse shaping of free electrons. The corresponding interaction of optical near fields with slow electrons has achieved much less attention, even though the lower electron velocity may enhance electron-near-field coupling for small nanoparticles. A first-principle theoretical study of such interactions has been reported very recently by N Talebi (2020 Phys. Rev. Lett.
125 080401). Building up on this work, we investigate, both analytically and numerically, the inelastic scattering of slow electrons by near fields of small nanostructures. For weak fields, this results in distinct angular diffraction patterns that represent, to first order, the Fourier transform of the transverse variation of the scalar near-field potential along the direction perpendicular to the electron propagation. For stronger fields, scattering by the near-field component along the electron trajectory results in a break-up of the energy spectrum into multiple photon orders. Their angular diffraction patterns are given by integer powers of the Fourier transform of the transverse potential variation and are shifting in phase with photon order. Our analytical model offers an efficient approach for studying the effects of electron kinetic energy, near field shape and strength on the slow-electron diffraction pattern and thus may facilitate the experimental observation of these phenomena by, e.g. ultrafast low-energy point-projection microscopy or related techniques. This could provide simultaneous access to different vectorial components of the optical near fields of small nanoparticles.
Early molecular markers for retrospective biodosimetry and prediction of acute health effects
Authors: Abend M , Blakely W F , Ostheim P , Schuele S , Port M 
Published: September 2021

Abstract
Radiation-induced biological changes occurring within hours and days after irradiation can be potentially used for either exposure reconstruction (retrospective dosimetry) or the prediction of consecutively occurring acute or chronic health effects. The advantage of molecular protein or gene expression (GE) (mRNA) marker lies in their capability for early (1–3 days after irradiation), high-throughput and point-of-care diagnosis, required for the prediction of the acute radiation syndrome (ARS) in radiological or nuclear scenarios. These molecular marker in most cases respond differently regarding exposure characteristics such as e.g. radiation quality, dose, dose rate and most importantly over time. Changes over time are in particular challenging and demand certain strategies to deal with. With this review, we provide an overview and will focus on already identified and used mRNA GE and protein markers of the peripheral blood related to the ARS. These molecules are examined in light of ‘ideal’ characteristics of a biomarkers (e.g. easy accessible, early response, signal persistency) and the validation degree. Finally, we present strategies on the use of these markers considering challenges as their variation over time and future developments regarding e.g. origin of samples, point of care and high-throughput diagnosis.
