Authors: Sedaghat Sam , Schmitz Frederick , Berek Johannes , Borchers Charlotte , Sedaghat Maya 
Published: August 2020

Abstract
Background: To assess the configuration of primary and recurrent synovial sarcoma on MRI. Additionally, to evaluate postoperative MRI regarding diagnostic performance and locoregional post-treatment changes.Methods: Twenty-five patients with histologically proven synovial sarcomas underwent 1.5-T MRI follow-up between 2012 and 2018. In all, 258 pre- and postoperative MRIs with available radiological and pathological were screened for primary/recurrent synovial sarcoma, diagnostic performance (false-positive/-negative and true-positive/-negative values) and post-treatment changes.Results: The median age of the patients was 40±15.2 years. The median volumes of primary and recurrent synovial sarcomas were 603 cm3 and 806 cm3, respectively. Of the patients 24% presented recurrences (n=6). In two patients false-positive diagnosis was made . There was one false-negative diagnosis of synovial sarcoma. Primary synovial sarcomas were significantly most often polycyclic/multilobulated (p=0.01) and heterogeneous in appearance with marked contrast enhancement. Recurrent synovial sarcomas showed two appearances: ovoid/nodular/homogeneous and polycyclic/multilobulated/heterogeneous, both with marked contrast enhancement. The most common post-treatment changes were subcutaneous (92%; p<0.001) and muscular edema (72%; p<0.001-0.003). Conclusion: While the configuration of primary synovial sarcomas was mainly polycyclic/multilobulated/heterogeneous, recurrent synovial sarcomas showed two shapes: ovoid/homogeneous and polycyclic/multilobulated/heterogeneous. MRI is still a highly valuable imaging modality for the postoperative surveillance of synovial sarcomas. Subcutaneous and muscular edema are common post-treatment changes.

Adgang til algoritmerne
Authors: Hjort Katrin 
Published: August 2020

Da jeg forsvarede min doktordisputats i 2012, argumenterede jeg for, at fremtidens strid inden for velfærd ville dreje sig om ”Adgang til excellence”, dvs. kampen om adgang til den bedste omsorg, uddannelse og sociale sikring. I dag er denne forudsigelse blevet skrækindjagende aktuel. Globale koncerner, nationer, institutioner og personer slås om adgangen til de mest effektive værnemidler mod Coronavirussen, herunder respiratorer, der kan forhindre, at vi lider kvælningsdøden.
Det var planlagt, at jeg 20. marts 2020 skulle holde en afskedsforelæsning, hvor jeg skulle tage udgangspunkt i den forelæsning, jeg holdt, da jeg i 2009 tiltrådte i mit professorat på Institut for Uddannelsesvidenskab på Syddansk Universitet. Ideen var, at jeg skulle beskrive udviklingen i dansk uddannelsesforskning i perioden 2010-2020. Men det blev ikke til noget, fordi universitetet blev lukket ned på grund af Corona-truslen. Vi blev konfronteret med en pandemi, der i værste fald bliver permanent, og som sætter helt nye vilkår for forskning og forskningsledelse.
Denne artikel forsøger at opsummere de tendenserne, vi i dag kan se inden for forskningsledelse og uddannelsesforskning. Nogle tendenser har manifesteret sig langsomt i løbet af de forløbne år. Andre er blevet radikaliserede på grund af krisen. Vi oplever på godt og ondt stærkere krav om anvendelsesorientering, en mere fremskreden digitalisering og en stærkere politisering af forskningen. Her vil jeg argumentere for, at striden i dag står om retten til at definere de algoritmer, der lægges til grund for håndtering af data. I Corona-krigen dukker foruroligende totalitære tendenser op. Mit håb er, at vi kan tage det så roligt, at vi kan bevare demokratiet.
Risikobaseret regulering som tillidsbevarende mekanisme i en uforudsigelig verden – rationaler, dilemmaer og paradokser
Authors: Henriksen Per 
Published: August 2020

Den moderne verden er kompleks og dynamisk. Usikkerhed og uforudsigelighed råder, og det stiller store krav til den måde, vi forvalter de samfundsmæssige processer på. For i en usikker verden er tilliden til samfundets centrale institutioner og de systemiske organisationer af endnu større betydning, når vi skal opretholde et velfungerende velfærdssamfund. Alligevel oplever vi en række sager, f.eks. relateret til SKAT, sundhedssektoren og den finansielle sektor, der udfordrer vores indlejrede oplevelse af tillid til systemet. Men hvorfor får vi disse sager, og kan de undgås? En del af svaret ligger muligvis i det paradoks, at vi konsekvent søger at håndtere usikkerhed og uforudsigelighed ud fra strategier og principper, der er rodfæstet i en verdensopfattelse af forudsigelige kausale sammenhænge. Artiklen argumenterer for, at den opfattelse har konsekvenser, fordi årsags-virknings-sammenhænge ofte kendetegnes ved det stik modsatte, nemlig uigennemskuelighed og deraf, uforudsigelighed. Artiklen tager afsæt i paradigmet om risikobaseret regulering og kontrol som eksponent for samfundsmæssige strømninger om rationel kausalitet, der har gjort risikostyring til et dominerende, men også tvetydigt svar på næsten alting. På den baggrund diskuteres 3 centrale udfordringer (strategisk ideologi, motiv- / praktik-kobling og risiko- / usikkerheds-tolkning), som risikobaseret regulering bør adressere for at afstemme intention med modernitetens natur. Den overordnede konklusion er, at ureflekteret tiltro til risikobaseret regulering og kontrol som universel metodik, er en farefyldt vej for samfundskontrakten, fordi paradigmet i praksis ignorerer verdens diskontinuitet og betydningen af samme.
Influence of ageing on circadian rhythm of heart rate variability in healthy subjects
Authors: Accardo Agostino , Merlo Marco , Silveri Giulia , Del Popolo Lucia , Dalla Libera Luca , Restivo Luca , Cinquetti Martino , Cannatà Antonio , Sinagra Gianfranco 
Published: August 2020

Background
The analysis of the circadian rhythm of heart rate variability (HRV) represents a relevant physiological tool to assess the vagal system. However, the influence of age (mostly >75 years) on HRV is not widely known.

Aims
The aim of this study was to evaluate the influence of age on HRV, particularly in the elderly and to identify a model of this relationship. The study was carried out by examining linear and nonlinear parameters extracted from HRV, including individuals over 75 years for which there is no research available.

Methods
Data from 140 healthy subjects were sex matched and divided into young (young group: 15–39 years old), adult (adult group: 40–64 years old) and senior (senior group: 65–90 years old) groups. 24-h Holter monitoring was used and several HRV parameters were extracted from time, and spectral and nonlinear analyses were examined.

Results
Time-domain parameters, mainly standard deviation of the NN interval (SDNN) and number of successive differences of intervals which differ by more than 50 ms, presented significant differences between the young group and the other two groups during the 24-h period, while normalized spectral parameters (LFn, HFn and low frequency/high frequency), as well as nonlinear parameters, mainly β exponent and fractal dimension, showed significant difference between the senior group and the other two groups. All these parameters showed a similar circadian rhythm with significant differences between the mean day and night values, especially in young and adult group cohorts. Moreover, a parabolic relationship between these parameters and age was highlighted with an opposite trend over about 60 years compared with younger people.

Conclusion
A progressive physiological autonomic imbalance is present in ageing. The inverse trend in the relation between HRV parameters and age found in the senior group could be mainly due to a faster fluctuation of RR. This should be considered when studying changes in the cardiac autonomic nervous control.
Correction of pes varus deformity in a Miniature Dachshund by true spherical osteotomy with a dome saw blade
Authors: Sellier Clément , Dosal Michael M. , Guthrie James W. , Fitzpatrick Noel 
Published: August 2020

Abstract

CASE DESCRIPTION
A 6-month-old male Miniature Dachshund was referred for examination and correction of a unilateral pes varus deformity.

CLINICAL FINDINGS
Clinical examination and diagnostic imaging revealed varus, procurvatum, and internal torsion of the distal aspect of the left tibia causing intermittent lameness.

TREATMENT AND OUTCOME
True spherical osteotomy performed with a dome-shaped saw allowed correction of the deformity in 3-D, and orthogonal internal plate fixation provided stabilization. No intraoperative or immediate postoperative complications developed. Outcome as judged by the clinician and the owners was satisfactory 2 weeks after surgery and excellent at each subsequent assessment. The patient remained free of clinical signs at the last follow-up 30 months after surgery.

CLINICAL RELEVANCE
To the authors’ knowledge, this case represented the first time a true spherical osteotomy was used to correct a pes varus deformity in a canine patient.
Disseminated pancreatic adenocarcinoma in an eclectus parrot (Eclectus roratus)
Authors: Le Roux Alexandre B. , Quesenberry Katherine , Donnelly Kyle A. , Donovan Taryn A. 
Published: August 2020

Abstract

CASE DESCRIPTION
A 15-year-old 0.412-kg (0.906-lb) sexually intact male eclectus parrot (Eclectus roratus) was evaluated because its owners found it lethargic and dyspneic at the bottom of its cage.

CLINICAL FINDINGS
The parrot was thin and had generalized muscle wasting, diffuse feather loss, pale mucous membranes, and melena. The coelomic cavity was distended and soft on palpation, with coelomic effusion suspected. Results of a CBC indicated leukocytosis with left shift heterophilia, including toxic heterophils, lymphopenia, and anemia. Plasma biochemical analyses revealed severe hyperamylasemia.

TREATMENT AND OUTCOME
Radiography revealed no evidence of a metallic foreign body but severe loss of coelomic detail, suggestive of a coelomic mass, coelomic effusion with coelomitis, or both. Ultrasonography and CT revealed severe accumulation of coelomic fluid; a large, heterogeneous, irregularly marginated, and moderately vascularized mass in the caudal aspect of the coelomic cavity; and multiple hepatic, coelomic, and pulmonary nodules. On the basis of a poor prognosis, the parrot was euthanized. Necropsy results confirmed exocrine pancreatic adenocarcinoma, with disseminated metastases in the liver, gastrointestinal tract, coelomic cavity, and lungs.

CLINICAL RELEVANCE
In birds, pancreatic adenocarcinoma is rarely reported but should be considered a differential diagnosis for hyperamylasemia, coelomic mass, coelomic effusion, or abnormal gastrointestinal signs, alone or in combination. Ultrasonography and CT can be useful in further evaluating such patients and should be considered in the diagnostic plan.
The Electrophoretic Pattern of Serum Proteins in Sheep with Naturally Acquired Gastrointestinal Nematode Infections
Authors: Nagy Oskar , Tóthová Csilla , Klein Róbert , Chovanová Frederika 
Published: August 2020

Abstract
The objective of this study was to describe the serum protein pattern in sheep with naturally acquired gastrointestinal parasitosis and to compare the distribution of protein fractions with the results obtained in animals with negative fecal examination results. Fecal and blood samples were taken from twenty-nine sheep positive for nematode eggs and twenty-four animals with negative results of fecal examination. Between the evaluated groups of sheep significant differences were noted in the relative mean values for all protein fractions and for albumin/globulin ratio (p<0.01 and p<0.001). The concentrations of total proteins showed no significant differences between both groups of sheep. The absolute mean values of albumin, α2-globulins and A/G ratio were significantly lower, the mean concentrations of α1-, β-, γ1- and γ2-globulins significantly higher in the nematode positive group of sheep (p<0.01 and p<0.001). In the nematode positive group the protein electrophoretic pattern showed a double α2-zone in three sheep and the γ-globulin zones were characterized by a diffuse higher broad and wide peaks. The presented results indicate that the gastrointestinal parasitic infections in sheep alter the distribution of serum proteins, and suggest their usefulness in animals with unchanged serum protein concentrations. The study brings new findings and extends the knowledge about the metabolic responses and consequences of gastrointestinal parasitic infections in sheep, particularly with regard to alterations in protein metabolism.
Small Intestinal Ganglioneuromatosis Accompanied by an Ulcer in a 13-Year Old Dog
Authors: Huber Doroteja , Gudan Kurilj Andrea , Hohšteter Marko 
Published: August 2020

Abstract
Ganglioneuromatosis is a rare disorder characterized by hyperplasia of intestinal ganglia including myenteric plexus and enteric nerve fibers. This disorder is generally described in children, but sporadic cases have also been described in adults. Most human cases arise in the colon and rectum. The disorder has also been described in dogs, mostly juveniles, but rarely in mature dogs with the oldest dog reported with this change being 9 years old.
We report the first case in an older dog from Croatia. A 13-year old female, mixed-breed dog had a history of diarrhea and weight loss. Ultrasound revealed focally-extensive markedly thickened small intestine. The changed part of the intestine, measuring 7 mm x 20 mm, was removed on laparotomy and delivered for histopathologic examination. Grossly, the intestine showed circumferential expansion of the intestinal wall, which was whitish in color. Microscopic findings included diffuse hyperplasia of the myenteric and submucous plexus. Focally in the affected tissue a subacute ulcer was evident, which was probably not the cause of intestinal signs, as it presented a localized lesion, while ganglioneuromatosis was a diffuse change in the affected tissue.
So far, ganglioneuromatosis was reported in young dogs, rarely in adult dogs. Our report shows that ganglioneuromatosis can also be encountered in older dogs. Although the lesion presents a rare finding, it should be listed as a differential diagnosis in dogs where infectious and neoplastic etiology has been ruled out as cause of diarrhea.
Optical soliton solutions to a (2+1) dimensional Schrödinger equation using a couple of integration architectures
Authors: Çankal Pelin Doğan , Yaşar Emrullah 
Published: August 2020

Abstract
In this work, we consider a (2+1) dimensional nonlinear Schrödinger system which appears in the theory of nonlinear optics and describe transmission of the optical pulses in optical fibers. We attain certain special type traveling wave solutions of the under investigated model by help of finite series expansion and auxiliary differential equations. In this manner, we exploit exp(−ϕ(ε)) and modified Kudryashov approaches as solution procedures. Moreover, we make tanh ansatz because of the being even order of the reduced ordinary differential equation. The obtained solutions are in the form of dark soliton, combined soliton, symmetrical Lucas sine, Lucas cosine functions, and periodic wave solutions. We present also some graphical simulations of the solutions corresponding to values of parameters which leads to a better understanding the phenomena.
Dirichlet Problem for Poisson Equation on the Rectangle in Infinite Dimensional Hilbert Space
Authors: Busovikov V.M. , Sakbaev V.Zh. 
Published: August 2020

Abstract
We study the class of finite additive shift invariant measures on the real separable Hilbert space E. For any choice of such a measure we consider the Hilbert space ℋ of complex-valued functions which are square-integrable with respect to this measure. Some analogs of Sobolev spaces of functions on the space E are introduced. The analogue of Gauss theorem is obtained for the simplest domains such as the rectangle in the space E. The correctness of the problem for Poisson equation in the rectangle with homogeneous Dirichlet condition is obtained and the variational approach of the solving of this problem is constructed.

Abstract
Several methods and materials are used in modern restorative dentistry for anterior dental lesions treatment. The desired aesthetic outcome can be obtained only with the correct treatment method correlated to case particularities. Sometimes, subjective and unrealistic approaches lead immediately or in time to undesirable dental restorations. The aim of the present paper is to evaluate the statistic distribution of aesthetic anterior dysfunctions detected on 425 patients from both genders that had restorative treatment during a period of 10 years. For each patient, there has been conducted an initial clinical examination and a photographic documentation was made. Also, each patient was asked to submit a questionnaire regarding his dental history. The results of the study represented the foundation for the discussions regarding the causes that led to aesthetic dysfunctions. The conclusions indicated that all errors that conducted to an initial failure of treatment are only connected with the medical decisions made by the dentist.
