Published: April 2020

AbstractWe present an open‐source system for Micro‐Aerial Vehicle (MAV) autonomous navigation from vision‐based sensing. Our system focuses on dense mapping, safe local planning, and global trajectory generation, especially when using narrow field‐of‐view sensors in very cluttered environments. In addition, details about other necessary parts of the system and special considerations for applications in real‐world scenarios are presented. We focus our experiments on evaluating global planning, path smoothing, and local planning methods on real maps made on MAVs in realistic search‐and‐rescue and industrial inspection scenarios. We also perform thousands of simulations in cluttered synthetic environments, and finally validate the complete system in real‐world experiments.

AbstractAdvancements in evidence-based psychosocial interventions, digital technologies, and implementation strategies (i.e., health services research products) for youth mental health services have yet to yield significant improvement in public health outcomes. Achieving such impact will require that these research products are easy to use, useful, and contextually appropriate. This paper describes how human-centered design (HCD), an approach that aligns product development with the needs of the people and settings that use those products, can be leveraged to improve youth mental health services. We articulate how HCD can advance accessibility, effectiveness, and equity, with specific consideration of unique aspects of youth mental health services.
Inanspruchnahme und wahrgenommene Barrieren des Gesundheitswesens bei Menschen mit Behinderung in Deutschland: Ergebnisse des GEDA 2014/2015-EHIS-Survey
Authors: Wetzel Lorena Denise , Rathmann Katharina 
Published: April 2020

Zusammenfassung
Hintergrund
Menschen mit Behinderung sind in der gesundheitlichen Versorgung benachteiligt. Eine bedarfsgerechte Gesundheitsversorgung verlangt einen gleichberechtigten Zugang zum Gesundheitswesen ohne Barrieren. Erstmals werden Inanspruchnahme und wahrgenommene Barrieren des Gesundheitswesens bei Menschen mit und ohne Behinderung, differenziert nach dem Grad der Behinderung (GdB) mittels repräsentativer Daten für Deutschland ausgewertet.

Fragestellung
Gibt es Unterschiede in der Inanspruchnahme und den wahrgenommenen Barrieren des Gesundheitswesens von Menschen mit im Vergleich zu Menschen ohne Behinderung?

Material und Methode
Datenbasis bildet der Survey „Gesundheit in Deutschland Aktuell 2014/2015“. Die Stichprobe umfasst 23.481 Personen mit und ohne Behinderung, wovon 1295 Personen (5,5 %) einen GdB <50 und 2395 Personen (10,2 %) einen GdB ≥50 aufweisen. Uni-, bi- und multivariate Analysen wurden für die abhängigen Variablen Besuch von Haus- und Fachärzt*innen, ambulante und stationäre Krankenhausaufenthalte und wahrgenommene Barrieren (u. a. Wartezeit auf einen Termin, Entfernung, Nicht-Bezahlbarkeit von Untersuchungen) vorgenommen.

Ergebnisse
Menschen mit Behinderung haben höhere Chancen für eine Inanspruchnahme des Gesundheitswesens als Menschen ohne Behinderung. Dabei zeigt sich ein behinderungsspezifischer Gradient nach dem GdB. Menschen mit Behinderung nehmen außerdem häufiger Barrieren im Gesundheitswesen wahr als Menschen ohne Behinderung z. B. für Untersuchungsverzögerungen aufgrund einer weiten Entfernung und weil sie sich ärztliche Untersuchungen nicht leisten können.

Schlussfolgerungen
Die Ergebnisse verdeutlichen den in der Behindertenrechtskonvention der Vereinten Nationen geforderten Abbau von Barrieren im Gesundheitswesen für Menschen mit Behinderung. Studien sind aufgefordert zielgruppenadäquate Bedarfe und Barrieren in der Gesundheitsversorgung, differenziert nach dem GdB, zu erfassen.
Culture and domestic violence amongst ever-married women in Malawi: an analysis of emotional, sexual, less-severe physical and severe physical violence

Published: April 2020

AbstractNearly 42% of ever-married women in Malawi have experienced some form of physical, sexual or emotional violence perpetrated by their current or most recent spouse – higher than the global estimate of 35%. This study used national-level data for ever-married women aged 15–49 years from the 2015 Malawi Demographic and Health Survey to explore the association between cultural factors and the likelihood of women experiencing sexual, physical and emotional violence after controlling for socioeconomic factors using multilevel logistic regression modelling. Key cultural factors found to be associated with violence against ever-married women in Malawi were type of marriage (polygynous or monogamous), age at marriage, religion and ethnicity. Husband's consumption of alcohol also emerged as a very important factor in violence against married women. Interventions to tackle violence against married women in Malawi should aim at promoting monogamous marriages and discouraging polygynous marriages, and address the culture of heavy alcohol consumption amongst husbands. Future studies could explore further if there are key lessons that families can learn from Muslim families and across ethnic groups.

AbstractMany studies have revealed that mantle‐derived mafic rocks can be more isotopically enriched than coexisting crustal felsic rocks. However, its origin remains to be elucidated. Here, we report on some Early Cretaceous (ca. 130 Ma) mafic rocks in Gan‐Hang Belt (South China) that are more isotopically enriched than the temporally and spatially associated granitoids. Relatively depleted Nd‐Hf isotopic signatures [εNd(t) = −0.4 to +0.6, εHf(t) = 3.4 to 4.8, εHf(t)zircon = −2.3 to +9.3], coupled with low zircon δ18OSMOW values (5.33–6.84 ‰) and geographical proximity to the exposed island arc rocks, indicate that the isotopically depleted Daixi alkali feldspar granites were dominantly derived from the relatively young Neoproterozoic accreted Shuangxiwu island arc sequences. Yet new and published whole‐rock Sr‐Nd‐Hf‐Pb‐O isotopic data [87Sr/86Sr)i = 0.70788–0.70833; εNd(t) = −7.6 to −3.5; εHf(t) = −6.8 to −1.9; (206Pb/204Pb)i = 18.028–18.108, (207Pb/204Pb)i = 15.565–15.577, (208Pb/204Pb)i = 38.198–38.341; δ18OSMOW = 4.5–5.5 ‰] highlight that the isotopically enriched Siling hornblende gabbros were predominantly sourced from an older, metasomatically enriched SCLM of adjacent Yangtze cratonic affinity. The arc crustal allochthon is assumed to have been tectonically emplaced onto the southeast Yangtze cratonic foreland, resulting in isotope inversion with younger crust on top of the older lithospheric mantle. Our results reveal a juxtaposition geometry of continental material after collision and accretion of island arcs by using isotope methods, which is independently supported by tectonic geological and geophysical studies. It suggests that ancient lithospheres should exist at depth within certain orogens associated with island arc accretion.
Future Circular Colliders succeeding the LHC

AbstractParticle physics has arrived at an important moment of its history. The discovery of the Higgs boson has completed the Standard Model, the core theory behind the known set of elementary particles and fundamental interactions. However, the Standard Model leaves important questions unanswered, such as the nature of dark matter, the origin of the matter–antimatter asymmetry in the Universe, and the existence and hierarchy of neutrino masses. To address these questions and the origin of the newly discovered Higgs boson, high-energy colliders are required. Future generations of such machines must be versatile, as broad and powerful as possible with a capacity of unprecedented precision, sensitivity and energy reach. Here, we argue that the Future Circular Colliders offer unique opportunities, and discuss their physics motivation, key measurements, accelerator strategy, research and development status, and technical challenges. The Future Circular Collider integrated programme foresees operation in two stages: initially an electron–positron collider serving as a Higgs and electroweak factory running at different centre-of-mass energies, followed by a proton–proton collider at a collision energy of 100 TeV. The interplay between measurements at the two collider stages underscores the synergy of their physics potentials.

AbstractThe autosomal dominant presentation of trichilemmal cysts is one of the most common single gene familial diseases in humans. However, the genetic basis for the inheritance and genesis of these lesions has remained unknown. We first studied patients with multiple trichilemmal cysts using exome and Sanger sequencing. Remarkably, 21 of 21 trichilemmal cysts from 16 subjects all harbored a somatic p.S745L (c.2234 G > A) mutation in phospholipase C delta 1 (PLCD1), a proposed tumor suppressor gene. In addition to this specific somatic mutation in their tumors, 16 of the 17 subjects with multiple trichilemmal cysts were also heterozygous for a p.S460L (c.1379 G > A) germline variant in PLCD1 which is normally present in only about 6% of this population. The one patient of 17 that did not show the p.S460L germline variant had a germline p.E455K (c.1363 C > T) mutation in the same exon of PLCD1. Among 15 additional subjects, with a history suggesting a single sporadic trichilemmal cyst, six were likely familial due to the presence of the p.S460L germline variant. Of the remaining truly sporadic trichilemmal cysts that could be sequenced, only half showed the p.S745L somatic mutation in contrast to 100% of the familial cysts. Surprisingly, in contrast to Knudsen’s two hit hypothesis, the p.S745L somatic mutation was always on the same chromosome as the p.S460L germline variant. Our results indicate that familial trichilemmal cysts is an autosomal dominant tumor syndrome resulting from two hits to the same allele of PLCD1 tumor suppressor gene. The c.1379 G > A base change and neighboring bases are consistent with a mutation caused by ultraviolet radiation. Our findings also indicate that approximately one-third of apparently sporadic trichilemmal cysts are actually familial with incomplete penetrance. Sequencing data suggests that the remaining, apparently sporadic, trichilemmal cysts are genetically distinct from familial cysts due to a lack of the germline mutations that underlie familial cysts and a decreased prevalence of the p.S745L somatic mutation relative to familial trichilemmal cysts.
VLBI observations of the H2O gigamaser in TXS 2226-184

Published: April 2020

Context.Outside the Milky Way the most luminous H2O masers at 22 GHz, called megamasers because of their extreme luminosity with respect to the Galactic and extragalactic H2O masers associated with star formation, are mainly detected in active galactic nuclei. In the case of the H2O maser detected in the nuclear region of the galaxy TXS 2226-184, the term gigamaser was used for the first time. However, the origin of this very luminous H2O maser emission has never been investigated in detail.Aims.We study the nature of the 22 GHz H2O gigamaser in TXS 2226-184 by measuring its absolute position for the first time at milliarcsecond resolution, by comparing the morphology and characteristics of the maser emission on very long baseline interferometry (VLBI) scales after about 20 years, and by trying to detect its polarized emission.Methods.We observed the 22 GHz H2O maser emission toward TXS 2226-184 three times: the very first time with the NRAO Very Long Baseline Array (VLBA, epoch 2017.45) and the next two times with the European VLBI Network (EVN, epochs 2017.83 and 2018.44). The first two epochs (2017.45 and 2017.83) were observed in phase-reference mode, while the last epoch (2018.44) was observed in full-polarization mode, but not in phase-reference mode to increase the on-source integration time. We also retrieved and analyzed the VLBA archival data at 22 GHz of TXS 2226-184 observed in epoch 1998.40.Results.We detected six H2O maser features in epoch 2017.45 (VLBA), one in epoch 2017.83 (EVN), and two in epoch 2018.44 (EVN). All but one are red-shifted with respect to the systemic velocity of TXS 2226-184; we detected only one blue-shifted maser feature and it is the weakest one. All the H2O maser features but the blue-shifted one are composed of two components with very different linewidths. For the first time we were able to measure the absolute position of the H2O maser features with errors below 1 milliarcsec. No linear and circular polarization was detected.Conclusions.We were able to associate the H2O maser features in TXS 2226-184 with the most luminous radio continuum clump reported in the literature. The comparison between epochs 1998.40 and 2017.45 reveals a difference in the morphology and velocity of the maser features that can be justified accounting for maser variability.

Published: April 2020

Zusammenfassung
Ziel der Studie Dimensionalität, Reliabilität und
konvergente Validität der deutschsprachigen Beck Scale for Suicidal
Ideation (BSS) sollen erstmalig in einer klinischen Stichprobe untersucht
warden.
Methodik 308 stationäre Patienten nach Suizidversuch/mit
akuter Suizidalität wurden rekrutiert (53,6% weiblich); 224
füllten die vollständige BSS sowie weitere Fragebögen
für Depression (DESC), Hoffnungslosigkeit (BHS), interpersonale
Variablen (INQ) und Defeat (DS-d)/Entrapment (ES-d) aus. Neben
konfirmatorischen Faktoranalysen (CFA, Prüfung von Modellen mit 1, 2, 3
und 5 Faktoren) zur Dimensionalitätsprüfung wurden
Pearson-Korrelationen zur Bestimmung der konvergenten Validität
berechnet.
Ergebnisse Insgesamt erzielt das 5-Faktoren-Modell den besten Fit; ohne
Berücksichtigung des RMSEA-Wertes ist der Modell-Fit zwischen den
verschiedenen Modellen allerdings vergleichbar. Im Rahmen der mehrfaktoriellen
Modelle entstehen inhaltlich vergleichbare Subskalen. Akzeptable interne
Konsistenzen zeigen sich nur für die Subskalen, die passive
Todeswünsche (α>0,80), aktive Suizidgedanken
(α>0,73) und suizidhandlungsbezogene Items
(α>0,70) erfassen. Der BSS-Summenscore sowie die Subskalen, die
passive bzw. aktive Suizidgedanken abbilden, korrelieren moderat mit DESC, BHS,
INQ und DS-d/ ES-d (r zwischen 0,25 und 0,66), während die
handlungsbezogene Subskala keine (INQ, Thwarted Belongingness) bzw. geringe
Assoziationen zeigt (r zwischen 0,14 und 0,27).
Schlussfolgerung Die CFAs liefern keinen eindeutigen Hinweis für
eine ein- oder mehrdimensionale Struktur der BSS. So ist die Auswertung
über den BSS-Summenwert trotz Hinweisen auf dessen Reliabilität
und konvergente Validität aus empirischer Sicht kritisch zu
bewerten.

Resumo
Objetivo O objetivo do presente estudo é identificar a incidência, os fatores predisponentes e o impacto prognóstico da perda de sangue em pacientes com escoliose neuromuscular submetidos a cirurgia corretiva.
Métodos Estudo de coorte retrospectiva, incluindo pacientes pediátricos com diagnóstico de escoliose neuromuscular submetidos a instrumentação e fusão vertebral posterior em um hospital universitário. As características dos pacientes foram coletadas no sistema de informações do hospital.
Resultados Um total de 39 pacientes foram incluídos no estudo. As perdas sanguíneas intraoperatórias foram de 962 mL, representando uma perda de 35,63% do volume sanguíneo; a perda de sangue foi extensa em 20 casos (> 30%) e apenas 7 pacientes não necessitaram de transfusão. O grupo de pacientes com perda maciça de sangue apresentou idade um pouco maior (13,75 versus 13,53 anos) e menor percentil do índice de massa corporal (IMC) (25 versus 50); para cada diminuição de 0,38 no IMC, as perdas sanguíneas intraoperatórias aumentaram 1% (p < 0,05). A concentração pré-operatória de albumina influenciou o percentual de perda de sangue e, para cada diminuição de 0,4 de albumina, a perda de sangue aumentou 1% (p < 0,05).
Conclusões Os fatores que mais contribuíram para as diferenças na perda sanguínea foram idade, IMC e concentração pré-operatória de albumina. Não houve associação significativa entre ângulo de Cobb, número de níveis de fusão e duração da cirurgia. Podemos concluir que esses pacientes se beneficiariam do controle nutricional pré-operatório.

Published: April 2020

Abstract
Objective To analyze the interobserver and intraobserver reproducibility of the visualization and continuity of the juncional zone (JZ) by three-dimensional (3D) ultrasound in infertile women, and to evaluate the sociodemographic, hormonal, and structural factors that influence these assessments.
Methods A prospective study conducted at the Assisted Reproductive Technology Unit of Hospital Senhora da Oliveira, in the city of Guimarães, Portugal. Transvaginal 3D ultrasonography was performed, and 2 volumes were generated per case. Two observers who were blinded to each other's work analyzed these volumes, choosing the best coronal section. Four months later, one of the observers performed the same methodology. The JZ visualization was classified as optimal, satisfactory, and unsatisfactory, and the JZ continuity, as continuous and discontinuous. The interobserver and intraobserver agreements were analyzed. The influence of hormonal, structural, and sociodemographic factors on the JZ was evaluated.
Results In total, 65 women were included in the present study. The interobserver reproducibility was substantial for JZ visualization and continuity (k = 0.635 and 0.753 respectively), and the intraobserver reproducibility was very good for JZ visualization and continuity (k = 0.884 and 0.816 respectively). Trilaminar endometrial pattern was associated with optimal JZ visualization (p = 0.012). The increase of 1 unit in the level of serum estradiol represents a 9.9% decrease in the odds of unsatisfactory visualization of the JZ (odds ratio [OR] = 0.9; 95% confidence interval [95%CI] = 0.814–0.996; p = 0.042). Endometriosis increases the odds of unsatisfactory visualization by 24 times (OR = 23.7; 95%CI = 1.262–437.057; p = 0.034). The prevalence of discontinuous JZs was of 60%. Myomas and endometriosis were associated with discontinuous JZs (p = 0.034 and 0.016 respectively).
Conclusion The assessment of JZ visualization and continuity by 3D ultrasound is reproducible enough to be used in the clinical practice.

AbstractChildren can have a variety of intracranial vascular anomalies ranging from small and incidental with no clinical consequences to complex lesions that can cause substantial neurologic deficits, heart failure, or profoundly affect development. In contrast to high-flow lesions with direct arterial-to-venous shunts, low-flow lesions such as cavernous malformations are associated with a lower likelihood of substantial hemorrhage, and a more benign course. Management of vascular anomalies in children has to incorporate an understanding of how treatment strategies may affect the normal development of the central nervous system. In this review, we discuss the etiologies, epidemiology, natural history, and genetic risk factors of three high-flow vascular malformations seen in children: brain arteriovenous malformations, intracranial dural arteriovenous fistulas, and vein of Galen malformations.
