Published: June 2023

Zusammenfassung
Hintergrund Die PAP (profunda artery perforator)-Lappenplastik zur
Brustrekonstruktion hat in den vergangenen Jahren an Popularität
gewonnen. Allerdings ist das Volumen bei der PAP-Lappenplastik in der Regel
beschränkt, sodass bei großvolumiger einseitiger
Brustrekonstruktion zwei PAP-Lappenplastiken entnommen und im Sinne eines
stacked PAP-Lappens in einer Brust eingesetzt werden können.
Falldarstellung Wir möchten den Fall einer 59-jährigen Patientin
demonstrieren, die sich als erkrankte BRCA-2-Trägerin nach
auswärtiger beidseitiger brustwarzensparender Mastektomie mit
Implantatrekonstruktion zur sekundären Rekonstruktion mittels
Eigengewebe vorstellte. Initial planten wir die beidseitige DIEP-Lappenplastik.
Bei der präoperativen Planung zeigten sich CT-tomographisch einseitig
keine Perforatoren, sodass lediglich eine linksseitige autologe Rekonstruktion
erfolgen konnte. Bei regelhaftem postoperativen Verlauf nach der
DIEP-Lappenplastik persistierte rechtsseitig die schmerzhafte Kapselfibrose und
es bestand der Wunsch zur autologen Konversion. Um ein ausreichendes Volumen
entsprechend der kontralateralen Brust zu erreichen, fiel der Entschluss zur
Rekonstruktion der rechten Brust mit einer beidseitigen PAP-Lappenplastik im
Sinne eines stacked PAP-Lappens.
Ergebnisse Beide Lappenplastiken boten genügend Volumen, um ein
ästhetisch zufriedenstellendes Ergebnis erreichen zu können und
hatten zusammen ein Volumen von 600 g im Vergleich zur Single
DIEP-Lappenplastik links von 716 g. Der stationäre Aufenthalt
betrug 7 Tage und war unauffällig. Die Brust war zu jeder Zeit weich und
es bestand klinisch kein Anhalt für Fettgewebsnekrosen bei der letzten
Nachkontrolle. Im Bereich der linken Entnahmestelle entwickelte sich eine
kleinflächige Wundheilungsstörung, welche konservativ abheilte.
Die Patientin ist beschwerdefrei und ist zufrieden mit dem Ergebnis.
Schlussfolgerungen Die PAP-Lappenplastik hat sich zu einer relevanten
Alternative zu herkömmlichen Brustrekonstruktionsverfahren entwickelt.
Der stacked PAP-Lappen kann eine sichere und effiziente Option für die
unilaterale großvolumige Brustrekonstruktionen sein. Die Perfusion und
der Abfluss über die nach kaudal angeschlossene Lappenplastik zeigten
sich suffizient und führten nicht zum Auftreten vermehrter
Fettgewebsnekrosen. Die Operationszeit hat sich in unserem Fall bei gleicher
Teamstärke nicht wesentlich von einer Single PAP-Lappenplastik
unterschieden. Zudem können durch die Möglichkeit, unilateral
zwei Lappenplastiken anzuschließen, ein symmetrisches Erscheinungsbild
an der Hebestelle der Oberschenkel und Folgeoperationen im Sinne multipler
Lipotransfers zur Volumenangleichung vermieden werden.

Published: June 2023

Background Sustainability is becoming increasingly important in radiology. Besides climate protection – economic, ecological, and social aspects are integral elements of sustainability. An overview of the scientific background of the sustainability and environmental impact of radiology as well as possibilities for future concepts for more sustainable diagnostic and interventional radiology are presented below.The three elements of sustainability:1. EcologyWith an annually increasing number of tomographic images, Germany is in one of the leading positions worldwide in a per capita comparison. The energy consumption of an MRI system is comparable to 26 four-person households annually. CT and MRI together make a significant contribution to the overall energy consumption of a hospital. In particular, the energy consumption in the idle or inactive state is responsible for a relevant proportion.2. EconomyA critical assessment of the indications for radiological imaging is important not only because of radiation protection, but also in terms of sustainability and “value-based radiology”. As part of the “Choosing Wisely” initiative, a total of 600 recommendations for avoiding unnecessary examinations were compiled from various medical societies, including specific indications in radiological diagnostics.3. Social SustainabilityThe alignment of radiology to the needs of patients and referring physicians is a core aspect of the social component of sustainability. Likewise, ensuring employee loyalty by supporting and maintaining motivation, well-being, and job satisfaction is an essential aspect of social sustainability. In addition, sustainable concepts are of relevance in teaching and research, such as the educational curriculum for residents in radiology, RADUCATION or the recommendations of the International Committee of Medical Journal Editors.

Harninkontinenz nach radikaler Prostatektomie: Risikofaktoren und Versorgungssituation
Authors: Baunacke Martin 
Published: June 2023

Zusammenfassung

Belastungsinkontinenz ist ein relevantes Risiko der radikalen Prostatektomie (RPE), welche die Lebensqualität der Betroffenen deutlich beeinträchtigt. Das Risiko eine Belastungsinkontinenz zu entwickeln hängt von prä-, intra- und postoperativen Faktoren ab. Insbesondere intraoperative Faktoren im Sinne unterschiedlicher OP-Techniken stehen dabei oft im Fokus, um die Kontinenzraten zu verbessern. Wenn es zur Belastungsinkontinenz nach RPE kommt, sollten die Betroffenen adäquat behandelt werden. Hier zeigen sich in Deutschland Hinweise auf ein Versorgungsdefizit. Zum einen gibt es Defizite in der Nutzung von Inkontinenzmaterialien. Zum anderen zeigt sich eine unzureichende operative Therapie der Belastungsinkontinenz nach RPE.

Published: June 2023

Objective The objective of this program evaluation was to describe the outcomes of daily neonatologist telerounding with the onsite advanced practice provider (APP) in a Level II neonatal intensive care unit (NICU), before and during the coronavirus disease 2019 (COVID-19) pandemic.
Study Design Bedside telerounding occurred with an onsite APP using a telehealth cart and paired Bluetooth stethoscope. Data collected by longitudinal and cross-sectional surveys and chart review before (May 2019–February 2020) and during (March 2020–February 2021) the COVID-19 pandemic were analyzed using descriptive statistics and thematic analysis.
Results A total of 258 patients were admitted to the Level II NICU before (May 2019–February 2020) and during (March 2020–February 2021) the COVID-19 pandemic. Demographic characteristics and outcomes, including breastfeeding at discharge and length of stay were similar pre- and postonset of the COVID-19 pandemic. Postrounding surveys by 10 (response rate 83%) neonatologists indicated parents were present in 80 (77%) of rounds and video was at least somewhat helpful in 94% of cases. Cross-sectional survey responses of 23 neonatologists and APPs (response rate 62%) indicated satisfaction with the program. Common themes on qualitative analysis of open-ended survey responses were “need for goodness of fit” and “another set of eyes” and “opportunities for use.”
Conclusion Daily telerounding with neonatologists and APPs in a Level II NICU supported neonatal care. Quality metrics and clinical outcomes are described with no differences seen before and during the COVID-19 pandemic.

Published: June 2023

AbstractThe Rh-catalyzed cross dehydrogenative coupling (CDC)/alkylation of the pyrazolylpyridine unit of GBT-440 proceeded smoothly under ambient conditions and selectively on the pyrazole unit while directed by the pyridine. The scope of these reactions was established by employing simple as well as conjugated olefins for CDC and various diazo esters and the TIPS-EBX reagent for alkylation. At the outset, a focused small molecule library around the bis-heterocyclic core of GBT-440 was developed via C–H functionalization.

Published: June 2023

Abstract
Introduction The management of complex anal fistulae remains a topical surgical problem. The choice and success of surgical management are based on the balance between healing and continence. Although porcine dermal collagen (Permacol Collagen Paste [PCP]- Covidien plc, Gosport, Hampshire, UK) represents a new generation of non-solid biomaterials, its results in anal fistulae are mixed.
Methods A multicenter observational retrospective analysis of consecutive patients with cryptoglandular anal fistula treated in four colorectal surgery units was performed between 2015 and 2020. Clinical cure of the fistula was the main outcome measure. Adverse events and alterations in anal continence were secondary outcomes.
Results The study included 119 patients (87 males, 71.1%), with a mean age of 53 years (IR 44–65). Most patients had complex (80.6%) and recurrent (91.6%) fistulae. With the first PCP treatment, the overall cure rate was 41.2% (49 patients) and 45.4% with the second treatment (5 out of 17 patients). The mean follow-up period was 17 months (IR 5–25). Healing was not affected by the location and type of fistula, the existence or not of a cavity, the number of tracts, or the administration of prophylactic antibiotics. After the PCP treatment, no patient in the series had worsening of continence. Morbidity affected 22.7% of the patients (27), with postoperative abscesses being the most frequent adverse event. There were no statistical differences between the four hospitals studied.
Conclusions Permacol collagen paste is a safe and easily reproducible therapy for complicated anal fistulae that has moderate efficacy. The overall success rate is slightly over 40%, with no detriment to fecal continence.

Published: June 2023

Abstract
Introduction Anal examination and videoanoscopy (VA) are rarely performed during colonoscopies. In recent years, there has been a considerable increase in lesions of sexually transmitted anal and rectal infections, but these conditions are not noticed or reported during routine colonoscopy.
Objective To raise awareness regarding the fortuitous findings of lesions and sexually transmitted infections (STIs) in colonoscopy exams and to demonstrate that anal examination and VA provide important information and should be routinely performed.
Methods We conducted a descriptive retrospective study in 16,132 patients screened by colonoscopy and VA between 2006 and 2018. Among numerous other findings, the presence of anal condylomata and sexually transmitted retitis or perianal dermatitis was observed. The rates of each finding were calculated, and the patients were subdivided by sex and into age groups by blocks of ten years.
Results Among the 16,132 colonoscopies performed, 26 cases of condyloma (0.16%) and 50 cases of proctitis or perianal dermatitis suspicious for STI (0.33%) were found.
Conclusion Performing anal examination and VA systematically in all routine colonoscopies enabled the identification of numerous anal conditions, including several fortuitous cases of STIs. The study proposes that anal examination and VA should be performed in all routine colonoscopies and, in suspected cases, complementary tests for STIs.

Published: June 2023

AbstractTinnitus is prevalent among military Veterans, yet there is a gap between the demand and the provision of services for tinnitus rehabilitation services within the Veterans Health Administration (VHA). We sought to understand tinnitus rehabilitation service needs and preferences among Veterans with bothersome tinnitus who use Veterans Affairs (VA) services. We conducted semistructured telephone interviews in 2019 with Veterans diagnosed with tinnitus, who reported it as bothersome. Veterans were purposively sampled to represent national VA users, with and without comorbid traumatic brain injury (TBI), and who were or were not interested in tinnitus rehabilitation services. Qualitative data were analyzed using a modified grounded theory approach. Among 40 Veterans interviewed (32 men, 8 women; 50% with TBI), 72.5% endorsed being somewhat/very likely to be interested in tinnitus rehabilitation services while 27.5% were very/somewhat unlikely. Themes related to Veterans' interest in tinnitus rehabilitation services included barriers and facilitators to participation and preferences for receiving tinnitus services (e.g., individual vs. group-based; in-person vs. remote access). Our findings highlight factors that influence Veterans' reported need and preferences for, and readiness to engage in, rehabilitation services for tinnitus. Personalized or otherwise adaptable approaches to program delivery may help ensure maximal uptake among Veterans.
Robustness improvement of a nitrogen-vacancy magnetometer by a double driving method
Authors: Gao Yanjie , Luo Zhengjie , Guo Hao , Wen Huanfei , Li Zhonghao , Ma Zongmin , Tang Jun , Liu Jun 
Published: June 2023

The nitrogen vacancy (NV) color center in diamonds is an electron spin that can measure magnetic fields with high sensitivity and resolution. Furthermore, the robustness of an NV-based quantum system should be improved for further application in other sensing methods and in the exploration of basic physics. In this work, the robustness of an NV magnetometer is improved by the double driving method. The sensitivity of the NV magnetometer was improved 2.1 times by strengthening the pumping power from 100 to 600 mW. In this process, thermal drift was introduced, which affects the measurement accuracy. The temperature drift of a diamond matrix was measured using an infrared camera, and the temperature change of a diamond host drifted to ∼80 K under high laser and microwave power. To address the drift of temperature owing to sensitivity improvement by pumping enhancement, the double driving method was introduced, to suppress the drift of the resonance frequency, to improve the robustness of a continuous-wave NV magnetometer. The magnetic noise density was improved from 10 to 1.2 nT/Hz1/2. This study checked the source of temperature noise in the process of measuring with the NV color centers and proposes a double driving measurement method to track the resonant frequency change due to environmental temperature drift and improve sensitivity. The findings of this study are useful in applying complex pulse protocols in high-level sensing applications based on solid-state spin.
Development of methods to overcome physiological seed dormancy of temperate annual pasture legumes to assist speed breeding
Authors: Peck David M. , Humphries Alan W. , Ballard Ross A. 
Published: June 2023

Context and aims Freshly harvested seeds of temperate annual pasture legume species have physiological dormancy (PD), which delays the growth of the next generation and is thus an impediment to speed breeding. The aim of this study was to develop a method or methods of PD breaking that can achieve high germination (≥90%) within 5 days of picking freshly harvested seed. Methods In a series of experiments, PD breaking methods by themselves and in combination were tested on burr medic (Medicago polymorpha). The most promising methods were then tested on other annual medic species (Medicago spp.), subterranean clover (Trifolium subterraneum), and alternative species from six genera. Key results The successful PD breaking method involved drying pods overnight at 45°C, extracting and scarifying seed, placing seed on filter paper in a Petri dish along with non-dormant seed, imbibing seed with 4 μM benzylaminopurine, sealing the Petri dish, and incubating in the dark at 15°C. Highly dormant genotypes required the additional treatment of removing the testa. Conclusions We have developed an effective way of breaking seed PD in the 11 pasture legumes species from the seven genera tested. The rapid breaking of seed PD will assist speed breeding of annual pasture legumes, making it less laborious and time-bound than currently used methods. Implications The PD breaking methods are expected to assist basic science studies of annual pasture legume species and may be applicable to other species and genera.
Effect of pre-fatigue on mechanical properties of modified double-base propellant
Authors: Yao Li , Chang-sheng Zhou , Xiu-min Yang 
Published: June 2023

Abstract
In this paper, fatigue tests of modified double-base propellant (CMDB) under cyclic loading under constant strain amplitude were carried out by using Dynamic Mechanical Analyser (DMA) at 20°C. The uniaxial tensile stress-strain curves at five strain rates after pre-fatigue were measured by a material universal testing machine, and the curves were similar to the uniaxial tensile test results of unfatigued propellant. The experimental results show that CMDB propellant has obvious strain rate correlation, and the initial elastic modulus and yield strength of the propellant increase with the increase of strain rate. The effect of prefatigue on the stress-strain behavior of CMDB propellant depends largely on the number of initial cycles and the strain stress loading amplitude. Under the initial cycle condition of pre-fatigue, the maximum tensile strength increases slightly with the increase of cycle number, while the elongation at break decreases with the increase of cycle number.

Published: June 2023

Abstract
Chasing efficient methods to generate and manipulate Cherenkov radiation (CR) is always the lofty target of many scientific researchers. In this work, by combining the optical topological transition (OTT) of graphene hyperbolic metamaterials (GHMs), we study the properties and clarify the mechanisms of the OTT of CR for the first time. Specifically, we indicate two representative examples to reveal the potential of the OTT in manipulating CR properties and further applications, which correspond to the ultrafast photothermal and nonlocal properties of graphene individually. These results and conclusions pave the way for the photonic devices and applications of CR.
Research on Opening Performance of Metal Diaphragm in Double Pulse Solid Rocket Motor
Authors: chen-yu Wang , Xuan Wu , xi-bin Luo 
Published: June 2023

Abstract
In order to investigate the effect of different double-pulse solid rocket motor metal diaphragm configurations on opening performance, a compartment device is designed. A modified Johnson-Cook principal structure model and damage criterion are used to simulate the pressure-bearing forces of the compartment structure based on finite element software. In order to obtain the parameters of J-C model, Quasi-static tensile tests at the strain rates of 10−4~10−1s−1 and temperatures of 300K~450K were carried out on 2A12 aluminium alloy dumbbell-type specimens. By varying the depth and width of the indentations on the metal diaphragm, and the finite element numerical simulation of the operation of the compartment under the action of solid rocket motor I and II pulses is also carried out. The results show that when the indentation depth is large, the indentation depth is the main factor affecting the opening pressure of the diaphragm; when the indentation depth decreases, the influence of the indentation width on the opening pressure of the diaphragm is more obvious.
