Antenatalinis vaisiaus rabdomiomų ir tuberozinės sklerozės nustatymas ultragarsu ir NIPT. Klinikinis atvejis ir literatūros apžvalga
Authors: Čerkauskaitė Akvilė , Machtejevienė Eglė , Serapinas Danielius
Published: December 2020

Rabdomiomos yra reta patologija, tačiau kartu ir dažniausias vaisiui atsirandantis širdies auglys, sudarantis daugiau nei 60 proc. visų vaisiaus širdies auglių. Rabdomiomų dažnis po gimimo yra apie 1 iš 40 000. Gerėjant ultragarsinio tyrimo technologinėms ir diagnostikos galimybėms, širdies rabdomiomos vis dažniau diagnozuojamos antenataliniu laikotarpiu. Jos gali būti lokalizuotos visose miokardo dalyse, tačiau dažniausiai randamos tarpskilvelinėje pertvaroje ir skilveliuose. Diagnozė galima nuo 19–20 savaitės, nors vidutiniškai nustatoma apie 28 savaitę. Apie 50–80 proc. atvejų, esant širdies rabdomiomoms, nustatoma tuberozinė sklerozė (TS) – autosominė dominantinė daugelį organų sistemų apimanti genetinė liga, pažeidžianti centrinę nervų sistemą, širdį, odą, tinklainę, inkstus ir plaučius. Širdies rabdomiomos gali būti ankstyviausias TS požymis. Konsultuojant pacientę bei šeimą, svarbu informuoti ne vien tik apie rabdomiomų sukeliamas komplikacijas ir prognozę, tačiau ir apie sąsajas su TS ir galimą jos diagnozę, pabrėžiant genetinio tyrimo svarbą. Straipsnyje aprašome retą antenataliniu laikotarpiu diagnozuotą širdies rabdomiomų ir tuberozinės sklerozės atvejį, taip pat literatūros apžvalgą nuo preatalinės diagnostikos iki paciento priežiūros gairių.

Authors: Tschuchnigg F. , Dich C.
Published: December 2020

Zusammenfassung Das Neubauprojekt Obervermuntwerk II (OMV II) der Vorarlberger Illwerke AG befindet sich in Vorarlberg, Österreich. Im Mai 2014 starteten die Bauarbeiten mit den Voreinschnitten der Zugangsstollen und zu Spitzenzeiten liefen vier Vortriebe zeitgleich. In der Ausschreibungsplanung wurden 2D-Finite-Elemente-Berechnungen der Maschinenkaverne zur Ermittlung des Primärspannungszustandes durchgeführt. Während der Vortriebsarbeiten der Maschinenkaverne folgten 3D-Finite-Elemente-Berechnungen. Die hohen Deviatorspannungen verursachten Spritzbetonabplatzungen in der rechten Kalottenhälfte, welche die Vortriebsarbeiten massiv einschränkten. Für die Festlegung einer dauerhaften Sanierung der Abplatzungen musste zuerst ein Verständnis für die Ursache geschaffen werden. Im vorliegenden Artikel wird neben einem groben Projektüberblick der Entscheidungsweg zur Festlegung der Sanierung wiedergegeben.
Building Information Modeling (BIM) in der Geotechnik – Aktuelle Entwicklungen und Erfahrungen/Building Information Modeling in Geotechnical Engineering – Recent developments and experiences
Authors: Henke S. , Lerch H.
Published: December 2020

Zusammenfassung Der vorliegende Beitrag diskutiert Erfahrungen und Gedanken zur Einbeziehung der Geotechnik in den Prozess der Planung unter Verwendung des Building Information Modeling (BIM). Da die Geotechnik beziehungsweise die Baugrundbeschreibung in der Praxis des Bauingenieurs eine wesentliche Planungsgrundlage darstellen, ist es unumgänglich, im Rahmen einer BIM-konformen Planung auch das oder die Baugrundmodelle in das BIM-Gesamtmodell einzubinden. Da die Entwicklung des BIM bislang vordringlich im Hochbau lag, wird dieser Beitrag dazu genutzt, die aktuell mögliche Umsetzung von BIM in der Geotechnik zu diskutieren. Es werden verschiedene Entwicklungen des BIM-Baugrundmodells im Lebenszyklus eines Bauwerkes von der Planung bis zur Nachnutzung vorgestellt und verschiedene Potenziale aber auch Schwierigkeiten, die es zu lösen gilt, angesprochen. Letztlich wird anhand eines Praxisprojektes mit hoher Komplexität bezüglich des Baugrunds dargestellt, welche Bausteine optimaler Weise in ein BIM-Baugrundmodell eingepflegt werden könnten.

Somit liegt das wesentliche Ziel dieser Publikation darin zu zeigen, dass die Einbindung des Fachmodells „Baugrund“ in das BIM-Gesamtmodell notwendig und (trotz in der Baupraxis teilweise vorhandener Einwände) auch möglich ist. Dem Leser werden sowohl die Notwendigkeit der Einbeziehung des Baugrundmodells in das BIM-Gesamtmodell als auch die Potenziale, die hieraus resultieren, verdeutlicht. Ein weiteres Ziel ist es, dass dem Leser die Besonderheiten einer 3D-Baugrundmodellierung verdeutlicht werden, da der Baugrund mit seinen üblichen Unsicherheiten und Variationen im Vergleich zu den anderen Fachdisziplinen mit üblicherweise klaren Vorgaben hinsichtlich zum Beispiel Geometrie und Material im BIM-Gesamtmodell eine besondere Stellung innehat.

Authors: Jäger W. , Meyer F.
Published: December 2020

Zusammenfassung Holzbalkendecken sind über Jahrhunderte eine typische und vielfältig verbaute hölzerne Deckenkonstruktion. Um sowohl neue gesellschaftliche Nutzungsanforderungen als auch den Erhalt der historischen Substanz zu gewährleisten, wurde 2017 am Lehrstuhl für Tragwerksplanung der TU Dresden, eine denkmalgerechte Methodik zur Ertüchtigung weit gespannter Holzbalkendecken mittels additiver Querschnittsergänzung unter Anwendung einer konstruktiven Klebung als zeitgemäße Holzverbindungstechnik erforscht. Im Ergebnis dieser Untersuchungen erhält das Kulturdenkmal Schloss Steinort in Sztynort, Republik Polen (ehem. Ostpreußen), seine bedeutenden und umfänglich polychrom bemalten Holzbalkendecken zurück, die dann zudem geeignet sind, größere Lasten aus den zukünftigen Nutzungsanforderungen zu tragen. Die untersuchte Sicherung und Ertüchtigung der Holzbalkendecken von Schloss Steinort ist eine innovative Kombination von neuen ingenieurwissenschaftlichen, konstruktiven Denkansätzen und hohen gesellschaftlichen Anforderungen moderner Denkmalpflege zu Gunsten des Fortbestandes des Kulturdenkmals.

Einsatz am Limit
Authors: Strecker W.
Published: December 2020

Sicherheitsrelevante Bauteile gibt es in den meisten technischen Produkten. Wie das Bild des Mountainbikers (Bild 1) zeigt, bewegen sich Mensch und Maschine am Limit. Der Biker vertraut auf die Funktion und Haltbarkeit seines Gefährts. Zuverlässig und widerstandsfähig sollen die Teile des Sportgerätes sein, grenzwertige Belastungen vertragen und den Biker nicht gefährden. Gesetzliche und normierte Vorgaben bestimmen den Orientierungsrahmen. Sie sind zum größten Teil den technischen Vorschriften und Regelwerken des Gesetzgebers und den internationalen Normen, wie der ISO 4210, EN 15194, zu entnehmen. Weiterhin werden die Anforderungen in den von Herstellern selbst entwickelten Prüfstandards beschrieben. Das Risiko seiner Sportart trägt der Nutzer jedoch selbst. Verantwortungsvoller Umgang damit ist empfehlenswert.

Die additive Reparatur von beschädigten Bauteilen und Formen ist häufig mit hohen Kosten verbunden. Durch die digitale Vernetzung wurde ein Mehrwert in der additiven und spanenden Reparatur geschaffen, der sowohl die Anlagenzeit und Ingenieurszeit reduziert und gleichzeitig auf variable Genauigkeitsanforderungen übertragbar ist. Anhand einer Turbinenschaufel wurde der Reparaturprozess getestet und kann in der Zukunft auf beliebige Bauteile übertragen werden.

The additive repair of damaged components and moulds is often associated with high costs, especially for SMEs. By digitally networking different components, an added value in additive and metal-cutting repair has been created, which reduces both machine time and engineering time and is at the same time transferable to variable accuracy requirements. The repair process was tested using a turbine blade and will be transferred to individual components in the future.

Aircraft Noise Modeling of Departure Flights based on Flight Track Data and Actual Aircraft Performance Parameters
Authors: Hübner Josephin , Strümpfel Christoph
Published: December 2020

Abstract The improvement of existing and the development of new operational noise abatement departure procedures (NADP) requires precise knowledge of the current aircraft noise situation in the vicinity of an airport. While the current noise situation is recorded using aircraft noise measurements, the estimation of future aircraft noise in the vicinity of airports must be calculated using suitable modeling methods (e. g. ECAC Doc 29). So far, the methods for estimating aircraft noise have been based on generic departure profiles and assumptions about flight operations procedures that do not match the real departure profiles, flight performance statuses and operational flight operations procedures sufficiently. In this article a method is presented that enables the calculation of aircraft noise contours of real departures using the aircraft noise modeling software Aviation Environmental Design Tool (AEDT). The exact calculation of aircraft noise contours from departures is based on a data set of flight history data (radar data), including the detailed estimation of aircraft performance parameters (including aircraft mass and engine thrust) and flight operations procedures (cutback and acceleration heights, flap schedule) along the departure trajectory. Then the data set is implemented in the modeling software and the calculated noise metrics (LA,MAX) are validated with real aircraft noise measurements of the corresponding flights.

Published: December 2020

Bu çalışmada, özellikle malign potansiyeli olan meme lezyonlarında ultrason eşliğinde uygulanan ince iğne aspirasyonunun güvenilirliği değerlendirildi. İnce iğne aspirasyon siyolojisi ile olguların eksizyonel biyopsilerini karşılaştırarak ince iğne aspirasyonunun kesin tanıya ulaştırabilirliği araştırıldı.

Hastanemiz Radyoloji Kliniği meme ünitesinde 2005-2009 tarihleri arasında memedeki kitlesine US eşliğinde ince iğne aspirasyon sitolojisi (İİAS) yapılan olgular dahil edildi. 163 olguda saptanan ve İİAS uygulanan 163 solid kitle retrospektif olarak tarandı.  İİAS’nin lezyon gruplarına göre özgüllük oranı, duyarlılık oranı, negatif öngörü oranı ve yanlış negatiflik oranı hesaplandı.

Sonografik olarak BIRADS 3 olarak değerlendirilen 124 kitlenin 116 tanesinin aspirasyon sonucu benign, 7 tanesinin sonucu tanısal olmayan sitoloji ve 1 tanesinin sonucu maligndi.  İİAS’nin BIRADS 3 lezyonlar için yanlış negatiflik oranı %0,8, negatif öngörü oranı %99.1 olarak hesaplandı.

BIRADS 4 olgularda IIAS sonuçları ile eksizyonel biyopsilerin sonuçları karşılaştırıldığında, sitolojisi adenozis olarak raporlanan bir olgunun biyopsi sonucunun da adenozis olduğu (%100), benign sitoloji olarak raporlanan 11 olgunun 1’i lobüler karsinoma insitu (%9), 3’ü(%27) fibroadenom, 7’si(%64) ise fibrokistik hastalık olarak raporlandı.  Sitoloji sonucu malign bildirilen 5 olgunun doku tanıları ise 3 infiltratif duktal karsinom (%60), 1 infiltratif lobüler karsinom (%20) ve 1 insitu karsinom (%20) olarak raporlandı.

Sitoloji sonucu duktal karsinom bildirilen 1 olgunun doku tanısı da duktal karsinom olarak raporlandı.

Sonografik olarak BIRADS 5 kriterdeki 7 kitlenin boyutları 13-24 mm arasında (ort 19 mm) idi. Bu lezyonların İİAS sonuçları 3 malign sitoloji(%43), 4 duktal karsinom idi (%57). Duktal karsinom olarak sitolojisi raporlanan olguların tamamının doku tanısı da duktal karsinom, malign sitoloji olarak raporlanan olguların 2’si lobüler karsinom(%67), 1’i ise duktal karsinom olarak raporlandı (%33).

Sonuç olarak İİAS iyi bir sitolog varlığında, radyoloji ve klinik ile beraber değerlendirildiğinde güvenilir sonuçlar vermekle beraber şüpheli ve uyumsuz sonuçlarda doku tanısı ile desteklenmesi gerekmektedir.

Pritom je potrebno naglasiti zadovoljstvo i potrebe studenata, kompetencije visokoškolskih nastavnika i očekivanja radnog tržišta. Cilj ovoga rada bio je ustvrditi koja je sastavnica didaktičko­metodičkog organiziranja sveučilišne nastave najvažniji čimbenik izvrsnosti nastavnog rada te kako sveučilišni nastavnici Univerziteta u Tuzli vrjednuju vlastitu izvrsnost didaktičko­metodičkog organiziranja nastavnog rada. Koristilo se analitičko­deskriptivnim upitnikom kao inačicom analitičko­deskriptivne metode, postupcima analize sadržaja i anketiranjem. Pretpostavljeno je kako postoji statistički značajna razlika u samovrjednovanju važnosti čimbenika izvrsnosti didaktičko­metodičke organizacije nastavnog rada visokoškolskih nastavnika Univerziteta u Tuzli te da se samovrjednovanja važnosti pojedinih čimbenika izvrsnosti sveučilišne nastave razlikuju s obzirom na dob, spol, znanstveno­nastavno/umjetničko zvanje, godine radnog iskustva u visokoškolskim ustanovama te znanstveno područje kojemu Fakultet pripada. Rezultati istraživanja pokazali su kako su izvrsnost planiranja i pripremanja te izvrsnost izbora nastavnih metoda najvažniji čimbenici ukupne izvrsnosti organiziranja sveučilišne nastave, a 90 % nastavnog osoblja ocjenjuje kako je nastava koju organiziraju visoke razine izvrsnosti.

Differential attainment in career progression in the NHS is a complex issue with many interplaying factors apart from individual protected characteristics. In this paper, we examine the attainment gap, causes for these disparities and some recommendations to reduce the gap. Our review shows that there is significant DA between groups of doctors on the basis of gender, ethnicity, race and country of primary medical qualification. The likely causes are bias, lack of opportunity, poor supervision, mentorship, sponsorship, dichotomous treatment of doctors based on training or non-training status and cultural exclusion. Data is not monitored or reported and there is little organisational accountability. Solutions are likely to include transparent data on recruitment as well as progression for benchmarking, training support for all doctors, initiatives which are sensitive to gender, parental responsibility, cultural heritage, language and robust supervision including mentorship and sponsorship. This scoping review forms part of the Alliance for Equality in Healthcare Professions project on Differential Attainment chaired by the British Association of Physicians of Indian Origin (BAPIO) and will be integrated into the Bridging the Gap project undertaken by BAPIO Institute for Health Research (BIHR). This work is part of six domains of doctors' careers in the NHS.

The unusual behavior of the spectral lines of NGC5548 during the STORM campaign demonstrated a missing piece in the structure of AGNs. For a two-month period in the middle of the campaign, the spectral lines showed a deficit in flux and a reduced response to the variations of the UV continuum. This was the first time that this behavior was unequivocally observed in an AGN. Our previous papers explained this as being due to a variable disk wind that acts as a shield and alters the SED. Here, we use Cloudy to create an atlas of photoionization models for a variety of disk winds, in order to study their effects on the SED. We show that the winds have three different cases: Case 1 winds are transparent, fully ionized, and have minimal effects on the intrinsic SED, although they can produce some line emission, especially He ii or FeKα. We propose that this is the situation in most of the AGNs. Case 2 winds, which have a He++–He+ ionization front, block part of the XUV continuum but transmit much of the Lyman continuum. They lead to the observed abnormal behavior. Case 3 winds have a H+ ionization front and block much of the Lyman continuum. The results show that the presence of these winds has important effects on the spectral lines of AGNs. They will thus have an effect on the measurements of the black hole mass and the geometry of the AGN. This atlas of spectral simulations can serve as a guide to future reverberation campaigns.

Introduction: Knowledge about the distribution of hepatitis C virus (HCV) genotype and its correlation with viral load are important for the decision of treatment and the prediction of disease progression, however such information is very limited in Nepal. Here, we investigated the distribution of HCV genotypes and viral load for HCV-infected patients from Kathmandu, Nepal.

Methodology: Ninety-six patients with HCV infection and not on antiviral therapy were enrolled from three different medical centers in Kathmandu valley, Nepal. Demographics were recorded and blood samples were collected. Plasma was separated and HCV RNA was extracted. Reverse transcriptase PCR (RT-PCR) was performed to measure the viral load, and virus genotype was determined.

Results: Genotype 3a (n = 53, 55.2%) was the most prevalent, followed by 1b (n = 19, 19.8%), 1a (n = 18, 18.8%), 5a (n = 3, 3.1%), and mix types (n = 3, 3.1%). The median viral load for HCV genotype 1a was 770,942 IU/mL (IQR, 215,268-3,720,075), 1b was 700,000 IU/mL (IQR, 431,560-919,000), 3a was 1,060,000 IU/mL (IQR, 641,050-6,063,500), 5a was 673,400 IU/mL, and mixed was 6,428,000 IU/mL. A correlation between genotype and viral load was observed (p = 0.02), of which genotype 3a showed a high viral load.

Conclusions: HCV genotypes 1a, 1b, 3a, and 5a were identified in Kathmandu, Nepal, and mixed genotype patients were observed in the patients studied. HCV genotype showed a correlation with viral load in patient plasma. This finding may contribute to the treatment and prevention of hepatitis C in Kathmandu, Nepal.

Introduction: The aim of this study was to investigate the drug-resistance and the molecular characterization of carbapenemases, ESBL, and aminoglycoside-modifying enzymes among Acinetobacter baumannii clinical isolates in Algerian hospitals.

Methodology: A total of 92 A. baumannii isolates were collected between 2012 and 2016. Antimicrobial susceptibility testings were performed for β-lactams, aminoglycosides, fluoroquinolones, trimethoprim-sulfamethoxazole, rifampicin and colistin. The phenotypic characterization of β-lactamases was investigated. For 30 randomly targeted strains, the carriage of the carbapenemases, ESBL and aminoglycoside-modifying enzymes -encoding genes was determined by PCR. Sequencing was carried out for carbapenemases and ESBL genes.

Results: Most of the 92 isolates studied were recovered from hospitalized patients (93.5%) and were mainly from intensive care units (51.1%) and orthopedics (19.6%). The strains were collected primarily from low respiratory tract (33.7%), wounds (23.9%) and urine (16.3%). Multidrug-resistant A. baumannii strains were prevalent (96.7%). High rates of resistance were observed for almost all antibiotics tested (>70%) excluding rifampicin (7.6%) and colistin (5.4%). For the five colistin-resistant strains, MICs ranged between 4 and 128 µg/mL. Positive MBL (83.7%) and ESBL (23.9%) strains were identified. Regarding β-lactams, the blaNDM and both blaSHV and blaCTX-M1 genes were detected in five and two strains respectively. Sequencing of the genes revealed the presence of blaNDM-1, blaCTX-M-15, and blaSHV-33. For aminoglycosides, aac(6’)-Ib, ant(2’’)-I and aph(3’)-VI genes were detected in three, seven and six strains respectively.

Conclusions: Here, we report the first co-occurrence of extended-spectrum β-lactamases SHV-33 and CTX-M-15, the carbapenemase NDM-1 and the emergence of colistin-resistant A. baumannii in Algerian hospitals.

Published: December 2020

Introduction: Septicemia is considered as an important cause of life-threating infections. The study was aimed at determining the incidence of septicemia considering different age groups and gender among suspected patients admitted to a tertiary care hospital in Iraq.

Methodology: A total of 168 blood samples were collected and cultured using BacT/Alert 3D automated system. The isolated pathogens were identified and subjected to antimicrobial susceptibility testing using automated Vitek 2 Compact system.

Results: Out of 168 blood samples, 53 (31.5%) gave positive microbial growth. Thirty-three samples (62.3%) came from male patients and 20 (37.7%) from female ones, both gender and microbial growth were significantly related (P < 0.05). Age group (21 year - 30 year) was found to have the highest percentage of positive growth (26.4%) while age group (51 year - 60 year) the lowest percentage (5.7%) of positive growth. Both microbial growth and age group were found to be associated to a significant level (P < 0.05). 36 isolates (67.9%) were Gram negative, 15 isolates (28.3%) were Gram-positive and 2 isolates (3.8%) were fungi. Salmonella typhi (41.7%) represented the most common pathogen isolated followed by Acinetobacter baumannii (22.2%). An isolate of Pseudomonas aeruginosa showed resistance to all antibiotics used.

Conclusion: Community-acquired septicemia occurred mainly in male than female. Salmonella typhi and Acinetobacter baumannii represented the most frequent causative agents of community-acquired septicemia. Antimicrobial susceptibility testing should be performed to detect the antibiotic of choice for each pathogen causing community-acquired septicemia.

Published: December 2020

Introduction: There have been several studies investigating the association between Toxoplasma gondii seropositivity and psychiatric disorders although there is insufficient data on causality. Suicide, depression, and anxiety disorders have been especially investigated in this regard. In this study, we aimed to investigate whether there is any causal association between Toxoplasma gondii seropositivity and suicide attempts in adolescents.

Methodology: This is a case-control study conducted between January and December 2019. A total of 27 adolescents who had attempted suicide and were aged between 12 and 18 years were included in the study. 26 age and sex ratio matched healthy volunteers were taken as the control group. A possible association between suicide attempts and Toxoplasma gondii serology (IgM and IgG) was investigated..

Results: The suicide attempt group consisted of 17 females and 10 males. The mean age was 15.9 ± 1.4 (13.5-17.9) years. Toxoplasma gondii IgG seropositivity was 3.7% (1/27) in the suicide attempt group and 3.8% (1/26) in the control group. There was no significant association between the suicide attempt group and the control group in terms of the presence of Toxoplasma gondii IgG antibodies (p > 0.05).

Conclusion: Our study is one of the few studies examining the association between Toxoplasma gondii seropositivity and suicide attempts in adolescents yet we did not find any significant association. Further evidence is needed to clarify this controversial issue.
Мicrovascular angina - terapeutic challenge. analisis of medical treatment options and a clinical case
Authors: Tsonev Svetlin
Published: December 2020

Etiology, diagnostics and treatment of patients with angina like symptoms and angiographically coronary arteries with no changes remain uncertain. Microvascular dysfunction is main cause for the symptoms in these patients. Chest pain is usually severe and longer than in patients with obstructive coronary artery disease and this results in reduced functional capacity and often hospitalizations. Classic scheme of antiischemic treatment is insufﬁcient in patients with microvascular dysfunctions, but metabolic class medicines reduce anginal episodes and their duration. We represent original data from our study and clinical case of a woman with long history of severe stenocardia and veriﬁed microvascular angina.
Status of knowledge of the broad-nosed weevils of Colombia (Coleoptera, Curculionidae, Entiminae)
Authors: Girón Jennifer C.
Published: December 2020

Broad-nosed weevils in the subfamily Entiminae (Coleoptera: Curculionidae) are highly diverse, not only in terms of number of species, but also in their sizes, forms and colours. There are eight tribes, 50 genera and 224 entimine species recorded from Colombia: seven genera and 142 species are considered endemic and only a handful of species, which are recognised as pests ofCitrusor potatoes, are broadly known. The large diversity of this subfamily in the country is only superficially known and even though genus level identifications are generally achievable, species identification remains quite challenging, due in part to limited access to broadly-scattered basic information. Summaries of available information and bibliographic resources for each of the tribes represented in Colombia are offered, along with a checklist of the species of Entiminae recorded from the country, obtained from literature and a pictorial key for tribal recognition. New combinations are proposed for eight species of the genusLanteriusAlonso-Zarazaga & Lyal. Information on the distribution of entimine species in Colombia is compiled for the first time, including complete references to each original description and available taxonomic revisions. About a third of the species of Entiminae remain as recorded from the country without specific locality information. In addition, genus level distributional maps are presented, generated from data obtained from four Colombian entomological collections. Lastly, some challenges for entimine identification in Colombia, which likely extend throughout the Neotropical region, are briefly discussed. This contribution aims, in part, to facilitate and promote entimine research in northern South America.
