1D recursive median filter based passive islanding detection strategy for grid‐connected distributed generations network
Authors: Mumtaz Faisal , Imran Kashif , Rehman Habibur , Bukhari Syed Basit Ali 
Published: March 2023

AbstractIn modern distribution networks, integration of distributed generations (DGs) at consumer premises is common. However, islanding detection in such a grid‐tied distributed generation (GTDG) network is the topmost challenge to ensure power quality and reliable operation. This paper presents a modified passive islanding detection scheme (MPIDS) for the GTDG network, using a One‐D recursive Median filter (ODRMF) algorithm. Firstly, at the point of common coupling (PCC), 3‐phase voltage is acquired. Next, the ODRMF is employed to extract 3rd harmonic and residuals from the acquired voltage signal. Afterward, two novel islanding detection indices developed are: (1) First change detection (FCD), which is calculated from the residuals, and (2) delta selected harmonic distortion (∆SHD), which is computed from 3rd harmonic content of the voltage signal. Finally, variations in the two indices are compared with the threshold to identify islanding. To validate the efficacy of the presented MPIDS, rigorous simulations in MATLAB/ Simulink are conducted on the UL‐1741 and IEEE 13‐bus GTDGs systems under different conditions. The results illustrate that the presented strategy is highly reliable in all assessed conditions and can detect the islanding as well as non‐islanding incidents effectively under balanced and unbalanced load/generation conditions with a very low non‐detection zone.
A localization scheme based on Improving Dynamic Population Monte Carlo Localization method for large‐scale mobile wireless aquaculture sensor networks
Authors: Lv Chunfeng , Zhu Jianping , Chen Gang 
Published: March 2023

AbstractLocalization is one of the essential problems in wireless sensor applications (WSNs). Most range‐free localization schemes for mobile WSNs are based on the Sequential Monte Carlo (SMC) algorithm. Multiple iterations, sample impoverishment and less sample diversity, leading to low localizing efficiency, are the most usual problems demanding to be solved in these SMC‐based methods. An improved localization scheme for mobile aquaculture WSNs based on the Improving Dynamic Population Monte Carlo Localization (I‐DPMCL) method is proposed. A population of probability density functions is proposed to approximate the unknown location distribution based on a set of observations through an iterative mixture importance sampling procedure, accompanied by node dynamic behaviours being analysed quantitatively or definitely. Threefold constrain rules are put forward in the I‐DPMCL scheme to decrease the iteration number and trade off iteration number and enough valid samples to obtain the optimum iteration number. Then, these localization behaviours, especial delay, are predicted based on the statistical point of view. Moreover, performance comparisons of I‐DPMCL with other SMC‐based schemes are also proposed. Simulation results show that delay of I‐DPMCL has some superiority to those of other schemes, and accuracy and energy consumption are improved in some cases of lower mobile velocity.
Decay of a photospheric transient filament at the boundary of a pore and the chromospheric response
Authors: Lindner P. , Schlichenmaier R. , Bello González N. , de la Cruz Rodríguez J. 
Published: March 2023

Context. The intermediate stages between pores and the formation of sunspots are a rare phenomenon and can be manifested as transient photospheric penumbral-like filaments. Although the magnetic field changes rapidly during the evolution of such filaments, they have not yet been shown to be connected to magnetic reconnection events.
Aims. We characterize the evolution of transient photospheric filaments around a pore and search for possible signs of chromospheric responses.
Methods. We analyzed observations of a pore in NOAA AR 12739 from the Swedish Solar Telescope, including the spectropolarimetric data of the Fe I 6173 Å and the Ca II 8542 Å line and spectroscopic data of the Ca II K 3934 Å line. The VFISV Milne-Eddington inversion code and the multi-line non-LTE inversion code STiC were utilized to obtain atmospheric parameters in the photosphere and the chromosphere.
Results. Multiple filamentary structures of inclined magnetic fields are found in photospheric inclination maps at the boundary of the pore, although the pore had never developed a penumbra. One of the filaments shows a clear counterpart in continuum intensity maps, in addition to photospheric blueshifts. During its decay, a brightening in the blue wing of the Ca II 8542 Å line is observed. The Ca II K 3934 Å and the Ca II 8542 Å lines show complex spectral profiles in this region. Depth-dependent STiC inversion results using data from all available lines yield a temperature increase (roughly 1000 K) and bidirectional flows (magnitudes up to 8 km s−1) at log τ = −3.5.
Conclusions. The temporal and spatial correlations of the decaying filament (observed in the photosphere) to the temperature increase and the bidirectional flows in the high photosphere and low chromosphere suggest that they are connected. We propose scenarios in which magnetic reconnection happens at the edge of a rising magnetic flux tube in the photosphere. This would lead to both the decay of the filament in the photosphere as well as the observed temperature increase and the bidirectional flows in the high photosphere and low chromosphere.
Vorkommen und Resistenzen von Bakterien in Proben aus Kaninchennasen
– eine retrospektive Auswertung
Authors: Meyer Cornelia , Maier Hannes , Hein Jutta 
Published: March 2023

Zusammenfassung
Gegenstand und Ziel Kaninchenschnupfen gehört zu den
häufigsten Herausforderungen in der tierärztlichen Praxis. Ziel
der vorliegenden Veröffentlichung war die Auswertung eingesandter Proben
aus Kaninchennasen (2015–2019) in Bezug auf Erregerverteilung und
Antibiotikaresistenzen.
Material und Methoden Jede Probe wurde auf 4 verschiedene Agarplatten
ausgestrichen sowie in einer nicht selektiven Bouillon angereichert. Die
Identifizierung der Bakterien erfolgte mittels MALDI
Biotyper
®
(MBT) (Bruker Daltonik GmbH,
Bremen, Deutschland) und die Antibiogrammerstellung mittels
Bouillon-Mikrodilutionsmethode gemäß Clinical and Laboratory
Standards Institute (CLSI, Wayne, PA).
Ergebnisse Ausgewertet wurden 1261 Proben. Bei den positiv befundeten
Proben (n=941) wurde in 79,1% eine Bakterienspezies und in
20,9% mehr als eine Bakterienspezies (Mischkultur) nachgewiesen.
Insgesamt wurden 150 unterschiedliche Spezies aus 14 Bakterienfamilien
differenziert. Vertreter der Pasteurellaceae wurden am häufigsten
identifiziert, gefolgt von Enterobacteriaceae, Pseudomonadaceae
und Staphylococcaceae.Ausgewertet wurden 467 Antibiogramme der am häufigsten nachgewiesenen
Bakterien mit möglicher klinischer Bedeutung (Pasteurella
multocida [14,6%], Pasteurella spp. [10,0%],
Staphylococcus aureus [5,9%], Pseudomonas aeruginosa
[5,4%] und Bordetella bronchiseptica [4,8%]). Chinolone
zeigten die größte und Clindamycin die geringste Wirksamkeit.
Weiterhin lag der höchste Anteil von MRSA an S.
aureus-Isolaten 2016 bei 23,1%.
Schlussfolgerungen und klinische Relevanz Da die für
Kaninchenschnupfen kausalen Bakterien meistens in den tieferen Bereichen der
Nase vorzufinden sind und der Nasenvorhof häufig mit ubiquitären
und coliformen Bakterien kontaminiert ist, wäre es sinnvoll, tiefe
Nasentupferproben bzw. idealerweise Nasenspülproben zu entnehmen.
Aufgrund der nachgewiesenen Erregervielfalt und einer mit der Erkrankung
einhergehenden Langzeittherapie sollte im Rahmen der Behandlung ein Antibiogramm
durchgeführt werden. Liegt kein Antibiogramm vor, ist Enrofloxacin wegen
seiner sehr guten Resistenzlage und Verträglichkeit Mittel der ersten
Wahl. Da jedoch Chinolone als „kritische“ Antibiotika eingestuft
werden, sollte ihr Einsatz auf ein Minimum beschränkt werden.
Tibial Plateau Leveling Osteotomy in small and large breed dogs: a
comparative retrospective study of complications and outcomes
Authors: Schuenemann Riccarda , Kaczmarek Jakub 
Published: March 2023

Abstract
Objective To compare complication rates and outcomes of small and large
breed dogs that had locking plate Tibial Plateau Leveling Osteotomy (TPLO)
performed due to cranial cruciate ligament disease during the same time period
at a single institution and identify potential influencing factors.
Material and methods 136 cases with TPLO performed at a single institution
between January 2013 and December 2015 were retrospectively reviewed. Dogs were
grouped by plate sizes (2.0, 2.4, 2.7, 3.5 and 3.5 broad) and by small breeds
(2.0–2.7 plate sizes) and large breeds (3.5 plates). Potential
influencing factors on lameness and complications were recorded from the
database and measured on radiographs and statistically compared.
Results Small dogs experienced fewer complications than large dogs
(10% vs. 22%) and not a single major complication. Small dogs
were significantly less lame at recheck and at long-term follow-up. Progression
of bone healing had an influence on the lameness grade of dogs at recheck after
TPLO. Distance of the most proximal screw from the joint was identified as a
risk factor for implant failure. The width of the patella ligament correlated
with body weight and uniformly increased 2.4 times after TPLO.
Conclusions TPLO in small breed dogs has a lower overall complication rate
than in large breed dogs. The TPLO plate should always be placed as close to the
joint as possible to reduce the risk of implant failure.
Clinical relevance TPLO can be recommended as treatment for cranial
cruciate ligament rupture (CCLR) in dogs of all sizes.
Myxosarkom in der Halsregion eines Teddy-Hamsters (Mesocricetus
auratus)

Published: March 2023

ZusammenfassungDieses Fallbeispiel zeigt ein bisher selten beschriebenes Myxosarkom in der
ventrolateralen Halsregion eines 1-jährigen Teddy-Hamsters. Die
zytologische Beurteilung eines Feinnadelaspirats aus der Umfangsvermehrung
zeigte zahlreiche pleomorphe Spindelzellen, die in hohen Mengen in einer
muzinösen Matrix gelegen waren. Zytologisch wurde aufgrund der
ausgeprägten Malignitätskriterien der Spindelzellpopulation der
Verdacht auf eine maligne mesenchymale Neoplasie geäußert. Die
Matrix war dabei hinweisend auf ein zugrundeliegendes Myxosarkom. Der Hamster
verstarb im Rahmen der operativen Entfernung der Zubildung. Die Histopathologie
zeigte eine vollständige Übereinstimmung mit den zytologischen
Befunden. In der Immunhistochemie stellte sich der Tumor Vimentin-positiv mit
Alzianblau-positiver Matrix dar und bestätigte die zytologische
Verdachtsdiagnose. Der Fall zeigt, dass die Zytologie als minimalinvasives
Diagnostikum auch beim Kleinsäuger angewendet werden kann und
Rückschlüsse auf die zugrundeliegende Pathologie von Zubildungen
ermöglicht. Zum biologischen Verhalten des Myxosarkoms beim Hamster ist
aufgrund der seltenen Fallbeschreibungen jedoch bislang wenig bekannt.

Published: March 2023

Abstract
Objectives Canine eosinophilic bronchopneumopathy (EBP) is a poorly
understood disease characterized by chronic inflammation of the lower airways.
To date, factors affecting the course of the disease are largely unknown. The
objective of this study was to investigate the influence of clinical,
laboratory, and environmental factors on therapeutic outcome in dogs with
EBP.
Material and methods Environmental and housing conditions, course of
disease, and response to treatment were evaluated using a standardized
questionnaire for owners of 29 dogs diagnosed with EBP from 3 different
veterinary referral centers in Germany. Data of diagnostic tests (hematology,
radiographs, bronchoalveolar-lavage-fluid-(BALF) cytology) were retrospectively
obtained from medical records. The influence of the different factors was
assessed using Fisher's-exact-test and Mann-Whitney-U- or
Kruskal-Wallis-test.
Results The proportion of neutrophilic granulocytes in BALF-cytology was
significantly higher in dogs with persistent clinical signs compared to dogs
that achieved clinical remission (p=0.029). Duration of clinical signs
before treatment was significantly longer in dogs with persistent clinical signs
(16±12 months) compared to dogs that achieved clinical remission
(6±7 months) (p=0.017).
Conclusion Early diagnosis and therapy have a decisive influence on the
success of treatment.
Clinical relevance Dogs with respiratory signs suspicious for EBP should
be evaluated in a timely manner to increase the likelihood of clinical remission
with an early start of therapy.
Baseline CT-Based Risk Factors for Atrioventricular Block after Surgical AVR
Authors: Claes Marie , Pollari Francesco , Mamdooh Hazem , Fischlein Theodor 
Published: March 2023

Abstract
Background We aimed to evaluate the impact of membranous interventricular septum (MIS) length and calcifications of the native aortic valve (AV), via preoperative multidetector computed tomography (MDCT) scan, on postoperative atrioventricular block III (AVB/AVB III) and permanent pacemaker implantation in surgical aortic valve replacement (SAVR).
Methods We retrospectively analyzed preoperative contrast-enhanced MDCT scans and procedural outcomes of patients affected by AV stenosis who underwent SAVR at our center (June 2016–December 2019). The study population was divided into two groups (AVB and non-AVB), and variables were compared with a Mann–Whitney's U-test or chi-square test. Data were further analyzed using point biserial correlation and logistic regression.
Results A total of 155 (38% female) patients (mean age of 71.2 ± 6 years) were enrolled in our study: conventional stented bioprosthesis (N = 99) and sutureless prosthesis (N = 56) were implanted. A postoperative AVB III was observed in 11 patients (7.1%). AVB patients had significant greater calcifications in left coronary cusp (LCC) -AV (non-AVB = 181.0 mm3 [82.7–316.9] vs. AVB = 424.8 mm3 [115.9–563.2], p = 0.044), LCC left ventricular outflow tract (LVOT) (non-AVB = 2.1 mm3 [0–20.1] vs. AVB = 26.0 mm3 [0.1–138.0], p = 0.048), right coronary cusp (RCC) -LVOT (non-AVB = 0 mm3 [0–3.5] vs. AVB = 2.8 mm3 [0–29.0], p = 0.039), and consequently in total LVOT (non-AVB = 2.1 mm3 [0–20.1] vs. AVB = 26.0 mm3 [0.1–138.0], p = 0.02), while their MIS was significantly shorter than in non-AVB patients (non-AVB = 11.3 mm [9.9–13.4] vs. AVB = 9.44 mm [6.98–10.5]; p=0.014)). Partially, these group differences correlated positively (LCC -AV, r = 0.201, p = 0.012; RCC -LVOT, r = 0.283, p ≤ 0.001) or negatively (MIS length, r = −0.202, p = 0.008) with new-onset AVB III.
Conclusion We recommend including an MDCT in preoperative diagnostic testing for all patients undergoing surgical AVR for further risk stratification.
Cerebral toxoplasmosis with neurological co-infection in people living with AIDS/HIV: results of a prospective cohort in São Paulo, Brazil
Authors: Telles João Paulo Marochi , Vidal José Ernesto 
Published: March 2023

AbstractBackground Concomitant neurological diseases in people living with HIV/AIDS (PLWHA) is a challenging subject that has been insufficiently evaluated by prospective clinical studies. The goal of the present study was to identify the clinical characteristics and outcomes of PLWHA with cerebral toxoplasmosis and neurological co-infections.Methods We conducted a prospective observational cohort study at a tertiary teaching center in São Paulo, Brazil, from January to July 2017. Hospitalized PLWHA aged ≥ 18 years with cerebral toxoplasmosis were consecutively enrolled. A standardized neurological examination was performed at admission and weekly until discharge or death. Diagnosis and treatment followed institutional routines; neuroradiology, molecular diagnosis, neurosurgery, and the intensive care unit (ICU) were available. The main outcomes were neurological coinfections and in-hospital death.Results We included 44 (4.3%) cases among 1,032 hospitalized patients. The median age was 44 (interquartile range [IQR]: 35–50) years, and 50% (n = 22) of the patients were male. The median CD4+ T lymphocyte count was of 50 (IQR: 15–94) cells/mm3. Multiple lesions on computed tomography were present in 59% of the cases. Neurological coinfections were diagnosed in 20% (n = 9) of the cases, and cytomegalovirus was the most common etiology (encephalitis: n = 3; polyradiculopathy: n = 2). Longer hospital stays (30 versus 62 days; p = 0.021) and a higher rate of ICU admissions (14% versus 44%; p = 0.045) were observed among PLWHA with neurological coinfections in comparison to those without them. The rate of in-hospital mortality was of 13.6% (n = 6) (coinfection group: 33%; no coinfection group: 8.6%; p = 0.054).Conclusion Neurological c-infections were common among PLWHA with cerebral toxoplasmosis, and cytomegalovirus was the main copathogen. The group of PLWHA with neurological co-infections underwent longer hospital stays and more frequent intensive care unit admissions. Additionally, this group of patients tended to have higher in-hospital mortality rate.

AbstractIn the last few decades, there have been considerable improvements in the diagnosis and care of Duchenne muscular dystrophy (DMD), the most common childhood muscular dystrophy. International guidelines have been published and recently reviewed. A group of Brazilian experts has developed a standard of care based on a literature review with evidence-based graded recommendations in a two-part publication. Implementing best practice management has helped change the natural history of this chronic progressive disorder, in which the life expectancy for children of the male sex in the past used to be very limited. Since the previous publication, diagnosis, steroid treatment, rehabilitation, and systemic care have gained more significant insights with new original work in certain fields. Furthermore, the development of new drugs is ongoing, and some interventions have been approved for use in certain countries. Therefore, we have identified the need to review the previous care recommendations for Brazilian patients with DMD. Our objective was to create an evidence-based document that is an update on our previous consensus on those topics.

Published: March 2023

Abstract
Introduction Cesarean scar pregnancy (CSP) is an increasing clinical condition that causes serious maternal morbidity and mortality. This study aimed to evaluate if inflammation markers measured by hemogram can aid in the diagnosis of CSP.
Materials and Methods A total of 86 patients were included in the study. The cases were divided as CSP (n: 42) and normal pregnancy (NP) (n: 44). At the time of admission, peripheral blood neutrophils, lymphocytes, monocytes, thrombocytes, systemic inflammatory index (SII) (neutrophil × platelet/lymphocyte), neutrophil–lymphocyte ratio, monocyte–lymphocyte ratio, and platelet–lymphocyte ratio were all measured. CSP and NP diagnoses were made by transabdominal or vaginal ultrasonography.
Results In the CSP group, mean age (p < 0.001), gravida (p < 0.001), parity (p < 0.001), number of surviving children (p < 0.001), number of abortions (p < 0.001), cesarean number (p < .001), dilatation and curettage count (p = 0.013), monocyte (M) value (p = 0.039) and monocyte/lymphocyte value (MLR) (p = 0.035) were significantly higher than the control group. The optimal M value cut-off value was found to be > 0.40, the sensitivity value was 78.57, and the specificity value was 50.00. AUC = 0.632 (SE = 0.061) for the MLR value. The optimal MLR cut-off value was found to be > 0.232, the sensitivity value was 61.90, and the specificity value was 63.64.
Conclusion Hemogram parameters, which are simple, inexpensive, and easily accessible, M and MLR are significantly higher in the diagnosis of CSP and can be used as an auxiliary parameter for ultrasonography.
Diagnostic Uncertainties in Tremor

Published: March 2023

AbstractThe approach and diagnosis of patients with tremor may be challenging for clinicians. According to the most recent consensus statement by the Task Force on Tremor of the International Parkinson Movement Disorder Society, the differentiation between action (i.e., kinetic, postural, intention), resting, and other task- and position-specific tremors is crucial to this goal. In addition, patients with tremor must be carefully examined for other relevant features, including the topography of the tremor, since it can involve different body areas and possibly associate with neurological signs of uncertain significance. Following the characterization of major clinical features, it may be useful to define, whenever possible, a particular tremor syndrome and to narrow down the spectrum of possible etiologies. First, it is important to distinguish between physiological and pathological tremor, and, in the latter case, to differentiate between the underlying pathological conditions. A correct approach to tremor is particularly relevant for appropriate referral, counseling, prognosis definition, and therapeutic management of patients. The purpose of this review is to outline the possible diagnostic uncertainties that may be encountered in clinical practice in the approach to patients with tremor. In addition to an emphasis on a clinical approach, this review discusses the important ancillary role of neurophysiology and innovative technologies, neuroimaging, and genetics in the diagnostic process.
