Published: September 2023

AbstractFault rupture is a common phenomenon in geotechnical engineering. To prevent rupture, laneway shoring is performed, prior to which, convergence deformation, failure criteria, and fracture development in soft rocks in the fault rupture zone are carefully analyzed. Then, a supporting structure corresponding to the actual situation of the soft rock in the rupture zone is created. Herein, the water-rich laneway shoring through the fault rupture zone of the Hongqingliang coal mine located in the Inner Mongolia Autonomous Region is taken as the research object. Then, the fracture development and characteristics of argillaceous siltstones and laneway shoring cross-fault rupture zone are studied. Site inspection, indoor and field tests, theoretical analysis, numerical simulation, and field monitoring were used for systematic fracture analysis. Results indicated that laneway shoring through the fault fracture zone in the Hongqingliang coal mine could help prevent disasters. This method was extended to laneway supports built through the fault rupture zones in mines in other areas of China.
Removal of carboxylated multi-walled carbon nanotubes (MWCNT-COOH) from the environment by Trametes versicolor: a simple, cost-effective, and eco-friendly method
Authors: Asefi Shaqayeq , Moghimi Hamid 
Published: September 2023

AbstractNanotechnology has increased the release of nanoparticles into the environment, which poses a risk to human health and the ecosystem. Therefore, finding ways to eliminate these hazardous particles from the environment is crucial. This research studied the ability ofTrametes versicolorfungi to remove carboxylated multi-walled carbon nanotubes. The study analyzed the impact of pH, MWCNT-COOH concentration, and initial fungal growth time on the removal process. The properties of the adsorbent were measured before and after the biosorption process using SEM, FTIR, and EDS techniques. The results showed that the live biomass ofT. versicolorwas more effective in removing nanoparticles than dead biomass at 30 °C and pH 7. An increase in carbon nanotube concentration from 5 to 20 mg. mL−1decreased biosorption potential from 100% to 28.55 ± 1.7%. The study also found that an increase in initial fungal growth time led to higher biomass production and adsorption capacity, increasing biosorption ability for concentrations > 5mg. ml−1. The biosorption kinetics followed a pseudo-second-order model and corresponded most closely to the Freundlich isotherm model. The adsorption capacity of live fungal biomass to remove multi-walled carbon nanotubes was 945.17 mg. g−1, indicating thatT. versicolorfungi have significant potential for removing carbon nanostructures from the environment.

Abstract
This study aims to investigate the temporal dynamics of the epiphytic protist community on macroalgae, during the summer months, with a specific focus on fungi, and the interactions between zoosporic chytrid parasites and the proliferation of the dinoflagellates. We employed a combination of environmental sequencing techniques, incubation of natural samples, isolation of target organisms and laboratory experiments. Metabarcoding sequencing revealed changes in the dominant members of the epiphytic fungal community. Initially, fungi comprised &lt; 1% of the protist community, mostly accounted for by Basidiomycota and Ascomycota, but with the emergence of Chytridiomycota during the mature phase of the biofilm, the fungal contribution increased to almost 30%. Chytridiomycota became dominant in parallel with an increase in the relative abundance of dinoflagellates in the community. Microscopy observations showed a general presence of chytrids following the peak proliferation of the dinoflagellate Ostreopsis sp., with the parasite, D. arenysensis as the dominant chytrid. The maximum infection prevalence was 2% indicating host-parasite coexistence. To further understand the in-situ prevalence of chytrids, we characterised the dynamics of the host abundance and prevalence of chytrids through co-culture. These laboratory experiments revealed intraspecific variability of D. arenysensis in its interaction with Ostreopsis, exhibiting a range from stable coexistence to the near-extinction of the host population. Moreover, while chytrids preferentially parasitized dinoflagellate cells, one of the strains examined displayed the ability to utilize pollen as a resource to maintain its viability, thus illustrating a facultative parasitic lifestyle. Our findings not only enrich our understanding of the diversity, ecology, and progression of epiphytic microalgal and fungal communities on Mediterranean coastal macroalgae, but they also shed light on the presence of zoosporic parasites in less-explored benthic habitats.

Zusammenfassung
Hintergrund 54% der deutschen Bevölkerung verfügt
über eine eingeschränkte Gesundheitskompetenz.
Eingeschränkte Gesundheitskompetenz ist assoziiert mit schlechteren
Gesundheitsoutcomes und höherer Inanspruchnahme des
Gesundheitssystems.
Ziel der Arbeit In der Pilotstudie wurden Effekte eines Patientenbriefs
auf die Gesundheitskompetenz nachstationärer Patienten einer Inneren
Klink mittels HLS-EU-Q47 untersucht. Zudem wurde der Bedarf an schriftlichen,
leicht verständlichen Informationen analysiert.
Methodik In einer randomisiert kontrollierten Studie (2016–2018)
wurden die Effekte des Patientenbriefs auf die Gesundheitskompetenz
nachstationärer Patienten mittels eines Fragebogens geprüft. Die
Interventionsgruppe (IG, n=242) erhielt 3 Tage nach Entlassung einen
Patientenbrief, die Kontrollgruppe (KG, n=175) nur den üblichen
ärztlichen Entlassbrief.
Ergebnisse 60% der Patienten wiesen eine eingeschränkte
Gesundheitskompetenz auf. Die Studie konnte keinen Einfluss der Patientenbriefe
auf das Gesamtkonzept Gesundheitskompetenz nachweisen. Die Analyse von
Einzelitems der Gesundheitskompetenz zeigte, dass das Verständnis von
ärztlichen Anweisungen sowie das Verstehen und Anwenden von
Informationen und Einnahmehinweisen zu Medikamenten stieg (Cohens
d≥0,20). Zudem berichteten Patienten einen hohen Bedarf an Informationen
nach Krankenhausaufenthalt (99%) und bewerteten den Patientenbrief als
informativ, verständlich und hilfreich.
Schlussfolgerungen Ein leicht verständlicher Patientenbrief
befähigt Patienten zum besseren Verstehen und Anwenden medizinischer
Informationen und Anweisungen. Patientenseitig besteht ein hoher Bedarf an
verständlichen Informationen nach Krankenhausaufenthalt.
Unter welchen Bedingungen können Menschen mit schwerer Demenz
im Pflegeheim von einer psychosozialen Mehrkomponenten-Intervention profitieren?
Authors: Diehl Kristina , Kratzer André , Gräßel Elmar 
Published: September 2023

Zusammenfassung
Hintergrund Psychosoziale Interventionen gelten mehrheitlich als wirksame
Mittel zur Behandlung von Demenzsymptomen. Allerdings gibt es kaum evaluierte
Konzepte für Menschen mit schwerer Demenz. Für die neu
entwickelte Mehrkomponenten-Intervention MAKS-s (Motorisch, Alltagspraktisch,
Kognitiv, Sozial, Versions für Menschen mit schwerer Demenz) konnte in
einer RCT-Studie in Pflegeheimen während der Covid-19 Pandemie keine,
mit den verwendeten Verfahren objektivierbare Wirksamkeit auf die
Lebensqualität oder psychische und Verhaltenssymptome nachgewiesen
werden.
Material und Methoden Am Ende der kontrollierten Phase (6 Monate nach
Studienbeginn) wurden auch die Pflege- und Betreuungskräfte der
Kontrollgruppe in der Durchführung von MAKS-s geschult. Alle geschulten
Therapeut*innen waren danach frei, zu entscheiden ob und in welcher
Intensität sie MAKS-s anwenden wollten (offene Phase). Mit Hilfe einer
schriftlichen Nachbefragung der Therapeut*innen nach weiteren 6 Monaten
sollten Prädiktoren für positive Auswirkungen der Intervention
auf Menschen mit schwerer Demenz identifiziert werden. Ebenso sollten Faktoren
bestimmt werden, die die Manualtreue, d. h. die in der Schulung
curricular vermittelte, standardisierte Vorgehensweise, vorhersagen
können. Grundlage der Datenerhebung war ein selbst entwickelter
Fragebogen, der die subjektive Einschätzung der MAKS-s
Therapeut*innen zu den drei Bereichen Struktur-, Prozess- und
Ergebnisqualität der MAKS-s Intervention erhob. Neben deskriptiven
Auswertungen wurden die Prädiktoren der Ergebnisqualität mit
Hilfe eines multiplen, linearen Regressionsmodells die der
Prozessqualität mittels binär-logistischer Regression
analysiert.
Ergebnisse 56% der geschulten MAKS-s Therapeut*innen
beantworteten den Fragebogen, 82% davon wendeten die Intervention
weiterhin an. Je ausgeprägter die normativen Einschränkungen
durch die Covid-19 Pandemie waren, desto häufiger waren
Manual-Abweichungen zu beobachten. Weniger Manual-Abweichungen wiederum standen
in signifikantem Zusammenhang mit mehr von den Therapeut*innen
wahrgenommenen positiven Auswirkungen der MAKS-s Intervention auf die Menschen
mit schwerer Demenz.
Schlussfolgerung Die Ergebnisse zeigen, dass die
„manualtreue“ Durchführung der psychosozialen MAKS-s
Intervention maßgeblich ist, für das Ausmaß der von den
Therapeut*innen erlebten positiven Wirkungen von MAKS-s.
Außerdem belegen die Befragungsergebnisse, dass
aktivitäts-einschränkende Pandemiemaßnahmen in
Pflegeheimen die wahrgenommene Wirksamkeit negativ beeinflussten.

Published: September 2023

Zusammenfassung
Hintergrund Granulomatöse Erkrankungen wie Sarkoidose können die Diagnostik bei onkologischen Erkrankungen erschweren, da Metastasen bildmorphologisch häufig nicht von Granulomen zu unterscheiden sind. Die vorliegende Kasuistik beschreibt Diagnostik und Therapie eines Patienten mit fortgeschrittener Sarkoidose und einem hepatisch metastasierten Rektumkarzinom mit schlussendlichem Erreichen eines kurativen Stadiums.
Fallbeschreibung Bei einem 71-jährigen Patienten wurde im Rahmen der Abklärung ungewollten Gewichtsverlustes sowie einer Anämie ein Adenokarzinom des Rektums diagnostiziert. Die weitere Umfelddiagnostik ergab bildmorphologisch den hochgradigen Verdacht auf multiple rechtshepatische, pulmonale und splenische Metastasen. Histologisch zeigten sich nach bronchoskopischer Biopsie der mediastinalen Lymphknoten jedoch nichtverkäsende Epitheloidzellgranulome als Manifestation einer bis dato nicht bekannten Sarkoidose. Aufgrund des stenosierenden Tumors erfolgte eine Rektumresektion mit Milzextirpation bei intraoperativ hochgradigem Verdacht auf Milzmetastasen. Histologisch zeigten sich in der Milz eine Beteiligung im Rahmen der Sarkoidose. Bei bildmorphologisch weiterhin suspekten rechtshepatischen Leberläsionen erfolgte postoperativ eine Stanzbiopsie einer Läsion, die histologisch sowohl eine Metastase des bekannten Rektumkarzinoms als auch eine Sarkoidose ergab. Es erfolgte eine pseudo(neo)adjuvante Therapie mit 5-Fluorouracil, Leukovorin und Oxaliplatin (FOLFOX) und Panitumumab (Anti-EGF-Antikörper). Bildmorphologisch zeigten sich posttherapeutisch 2 Leberläsionen regredient, mehrere weitere größenstabil. Es erfolgte eine erweiterte Hemihepatektomie rechts mit histologischem Nachweis von sowohl Metastasen als auch Sarkoidose-Herden. Der zu diesem Zeitpunkt tumorfreie Patient wurde in die engmaschige Nachsorge entlassen, die sich im weiteren Verlauf (13 Monate) bildmorphologisch ohne Rezidivhinweis zeigte.
Diskussion Das gleichzeitige Auftreten von metastasierten Tumorerkrankungen und Sarkoidoseherden führt zu einem diagnostischen Dilemma, da die Manifestationen bildmorphologisch kaum unterschieden werden können. Dieser Fallbereich zeigt, dass eine umfassende histologische Aufarbeitung der unterschiedlichen betroffenen Organe mit konsekutiven Resektionen schlussendlich zu einer Tumorfreiheit des Patienten führen kann.

Published: September 2023

AbstractWe present the case of a 58-year-old female with a history of a bleeding duodenal peptic ulcer. Endoscopic hemostasis was unsuccessful; therefore, a transcatheter arterial embolization of a culprit vessel was performed. She was admitted to the hospital two months later because of obstruction of the common bile duct with cholangitis. Attempts to endoscopically place a biliary stent failed. The treating medical team opted for a surgical choledocho-jejunostomy. After 20 months, she presented with a melena and a severe anemia. Diagnostic work-up revealed portal vein thrombosis with portal cavernoma and bleeding choledocho-jejunostomy varices. The case presents and discusses rare complications of duodenal ulcer disease, as well as possible causes and treatment options.

Published: September 2023

Abstract
Introduction Chronic consumption of a high-calorie diet compromises the
gut microbiota and the integrity of the intestinal wall, which causes
translocation of bacterial lipopolysaccharides (LPS) into the blood. This
elicits the secretion of pro-inflammatory cytokines, resulting in inflammation.
However, how a high-fat high carbohydrate diet affects intestinal permeability
and its possible role in the development of prediabetes have not been
investigated. This study investigated the effects of HFHC diet-induced
prediabetes on gut microbiota and intestinal permeability in male Sprague Dawley
rats.
Methods The animals were randomly assigned into the non-prediabetic (NPD)
and diet-induced prediabetic (PD) groups (n=6) for 20 weeks. Then, the
fecal samples were analyzed to measure the gut microbiota level of
Firmicutes, Bacteroidetes, and Proteobacteria in both animal
groups. Blood glucose, plasma insulin, serum zonulin, plasma LPS, soluble CD14,
tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), C-reactive
protein (CRP), and intestinal fatty-acid binding protein (IFABP) concentrations
were measured.
Results The PD group had a reduction in the Firmicutes and an
increase in Bacteroidetes and Proteobacteria levels compared to
those in the NPD group. Blood glucose, insulin concentration, serum zonulin, and
plasma sCD14 concentrations in the PD group increased significantly, while
plasma LPS concentrations were similar to the NPD group. Concentrations of
plasma TNF-α, IL-6, CRP, and IFABP, an intracellular protein expressed
in the intestine, increased in PD compared to the NPD group.
Conclusions the study results cumulatively suggest that chronic
consumption of the HFHC diet may be associated with the dysregulation of gut
microbiota, leading to increased intestinal permeability.

Abstract
Introduction The American Association of Neurological Surgeons (AANS), North American Skull Base Society (NASBS), American Rhinologic Society (ARS), and American Neurotology Society (ANS) fellowship directories are important information repositories for skull base surgical fellowship programs. However, there is limited research on the amount and depth of information available through these resources. The objective of the present study is to assess Web site accessibility and information availability for individual fellowship programs listed within the AANS, NASBS, ARS, and ANS fellowship directories.
Methods Lists of all accredited skull base surgical programs were obtained from the AANS and NASBS fellowship directories. Duplications in listed programs were removed, and systematic queries via an online search engine were conducted to identify fellowship Web sites. From each available Web site, information pertaining to 24 different variables was collected and organized into two categories—recruitment and education. Differences in the availability of information on recruitment and education were then compared across Web sites and contextualized relative to other surgical specialties.
Results After excluding duplicates, 113 fellowship programs were identified, of which 99 (87.6%) had accessible Web sites. Of the 48 listed by the NASBS, direct Web site links were available for 33 (68.8%), email contacts were accessible for 32 (66.7%), and phone numbers were listed for 6 (12.5%). Of the 39 programs listed by the AANS, none included Web site links, 38 (97.4%) provided an email contact, and 39 (100%) listed a departmental contact telephone number. All 28 (100%) programs listed by the ANS provided a phone and email contact in addition to a Web site link to each institutional Web site. Of the 33 programs listed by the ARS, 29 (88%) had a departmental contact telephone number, 31 (94%) had an email contact available, and 4 (12%) had a program Web site link directly available from the database Web site. Of the 99 total programs, fellowship Web sites displayed an average of 5.46 (42.0%) of the 13 recruitment features and 4.80 (42.6%) of the 11 education features. Programs in the geographic Northeast were significantly less likely to present information pertaining to recruitment (p = 0.023). Furthermore, programs in geographic Northeast and West were significantly less likely to present information focused on surgical training and/or education (p = 0.006).
Conclusion Although many skull base fellowship programs have maintained comprehensive program Web sites, certain critical aspects remain deficient, and some programs provide little to no information. Providing more detailed information about programs can prove mutually beneficial for fellowship program directors and candidates.

Published: September 2023

Abstract
Background Autologous tissue has become the gold standard in breast reconstruction. The use of a deep inferior epigastric perforator (DIEP) flap has the advantages of giving a natural appearance to the reconstructed breast and being associated with lower morbidity at the donor site when compared with the transverse rectus abdominis myocutaneous flap. Venous complications such as venous thrombosis and insufficiency remain the main causes of flap loss and surgical revisions. The aim of this study was to evaluate the influence of superficial venous drainage of the DIEP flap and the addition of a second venous anastomosis have on flap survival.
Methods This was a retrospective cohort study collected from a prospective database maintained by our institution. Data was obtained from the medical records of female patients who underwent mastectomy and breast reconstruction with a DIEP flap between March 2010 and March 2017. We evaluated 137 DIEP patients with unilateral breast reconstructions. In 64 (46.7%) the deep venous system was chosen and 73 (53.3%) had an additional superficial vein anastomosed.
Results Out of the 137 patients evaluated, there were 16 (11.67%) cases of revision, 14 (10.21%) were due to venous thrombosis. Twelve cases (8.75%) of flap loss were reported. Reoperation rate was lower in the dual venous drainage group when compared with the single venous drainage group (p = 0.005), as was the rate of flap loss (p = 0.006) and reoperation due to venous thrombosis (p = 0.002). Out of the 125 DIEP flaps, fat necrosis was clinically identified in 7 (5.1%) cases, and the rate was lower in the dual venous drainage system group (p = 0.01).
Conclusion Dual venous drainage of a DIEP flap appears to reduce the rates of venous thrombosis, reoperation, total flap loss, and fat necrosis.

Abstract
Background Patients with complex lower extremity (LE) wounds and single-vessel LE runoff (1-VRO) are often considered for amputation. While more challenging, free tissue transfer (FTT) is a means for limb salvage. This study aims to demonstrate the feasibility of limb salvage with FTT in patients with 1-VRO.
Methods Patients undergoing FTT by a single surgeon between 2011 and 2021 were retrospectively reviewed. Data collected included demographics, wound characteristics, vascular status, and operative details. Patients were divided into cohorts based on 1- versus 3-VRO of tibial vessel inflow. Outcomes of interest included postoperative complications such as flap necrosis, flap success, limb salvage, and ambulatory status.
Results A total of 188 patients underwent FTT to LE, with 25 patients (13.3%) having 1-VRO. Patients with 1-VRO had a comparable prevalence of diabetes (56.0% vs. 50.0%, p = 0.569) and end-stage renal disease (8.0% vs. 3.7%, p = 0.319). Osteomyelitis was more common in the 1-VRO group (80.0% vs. 60.1%, p = 0.056). FTT donor sites and flap composition were similar between cohorts. At mean follow-up of 21.2 months (interquartile range 24.5:5.6, 30.1 months), limb salvage rates were similar between cohorts (84.0% vs. 91.4%, p = 0.241), with no significant differences in ambulatory status or mortality. Higher complication rates occurred in the 1-VRO cohort (48.0% vs. 21.5%, p = 0.004), of which partial flap necrosis was more prevalent in the 1-VRO group (8.0% vs. 1.2%, p = 0.029). There was no difference in flap success rates between groups (p = 0.805). More postflap angiograms were performed in the 1-VRO group (32.0% vs. 9.2%, p = 0.001), but there was no difference in need for repeat percutaneous endovascular intervention between groups.
Conclusion This study demonstrates that FTT reconstruction to the LE remains a reliable reconstruction option for limb salvage in patients with single-vessel supply to the LE. Reliance on advanced perioperative management and patient optimization is effective at reducing negative outcomes.
