Authors: Groen Simon P. N. , Menninga Marijke C. , Cath Daniëlle C. , Smid Geert E. 
Published: September 2022

BackgroundRecognition that the loss of a loved one may result in prolonged grief disorder (PGD) has gained broad attention recently. PGD may disturb daily functioning to such a degree that mental health treatment is required. Because PGD symptoms often resemble symptoms of common mental disorders (CMD) such as anxiety, depressive, and post-traumatic stress disorder, clinicians may not consider a PGD diagnosis. Moreover, cultural varieties in expression of PGD may complicate recognition. This study explores the prevalence of PGD among both natives and refugees with anxiety, depressive, or trauma- and/or stressor-related disorders as well as clinicians' awareness and knowledge of PGD symptoms. In addition, a psychoeducation module on PGD symptoms is developed through patient expert collaboration.MethodsPrevalence of PGD symptoms is investigated among 50 participants who are referred to outpatient clinics for anxiety, depression, or post-traumatic stress, using the Traumatic Grief Inventory—Self Report Plus (TGI-SR+) and the Bereavement and Grief—Cultural Formulation Interview (BG-CFI). Clinicians will be interviewed on knowledge (gaps) with respect to PGD symptoms. Finally, focus groups with patient experts are held to develop a psychoeducation module tailored to the patients' needs, norms and values.ResultsThis study will show prevalence of PGD among patients who are referred for anxiety, depression, and post-traumatic stress, awareness and knowledge of clinicians on PGD symptoms, and will offer patient expert informed psychoeducation.DiscussionResearch on prevalence and recognition of PGD is vital. Study results of the prevalence of PGD will be compared to previous studies. Recognition of PGD as distinct disorder from CMDs requires clinicians' awareness of symptoms related to the loss of a loved one. Thereby, clinicians need to take cultural aspects related to death, bereavement and mourning into consideration.Ethics and disseminationThe study protocol will be carried out in accordance with relevant guidelines and regulations. Exploratory research to assess the prevalence of PGD in patients suffering from CMDs will facilitate adequate diagnosis by increasing clinician's awareness of PGD symptoms. Tailored PGD psychoeducation, co-created by culturally diverse patient experts and clinicians will be made publicly available.

BackgroundThe COVID-19 pandemic is striking the world with serious public health and economic losses. Complying with precautionary measures is affected by knowledge, attitudes, and practices (KAP) toward COVID-19 among the general public, so it is urgent to know the public's awareness of COVID-19 as to promote the epidemic management of COVID-19 in China.MethodsAn online sample of Chinese residents was recruited. We administered a self-developed online KAP survey comprising 39 questions regarding awareness of COVID-19, transmission mode, symptoms, preventive measures, and respondents' attitudes and practices with respect to COVID-19. The total score of each item (knowledge, attitudes, and practices) adopts the ten points system, score of KAP is 30 points. Descriptive statistics, analysis of variance, and binomial logistic regression were used in the statistical analysis.ResultsAmong respondents, average scores for COVID-19-related knowledge, attitudes, and practice were 8.94 ± 0.79, 5.97 ± 1.58, and 7.03 ± 3.14, respectively. 91.2% were aware that COVID-19 is an acute viral infection and 99.95% knew that wearing a mask is one way to prevent COVID-19 infection. Participants correctly identified the symptoms of COVID-19 with a high accuracy rate of over 85%.ConclusionMany adults in the present study had adequate knowledge, a positive attitude and engaged in correct practices against COVID-19. People in China have a high awareness of epidemic prevention and control. However, conducting KAP surveys among people with different demographic characteristics at different stages of the epidemic is important to improve public health education and implement proper COVID-19 prevention and control measures.

Published: September 2022

BackgroundPressure ulcers (PUs) are an indicator of the quality of nursing care and nurses can prevent PUs well if they have sufficient knowledge. Numerous studies in this field have reported different results. The aim of this study was to estimate the pooled score of nurses' knowledge about PU prevention based on the Pressure Ulcer Knowledge Assessment Tool (PUKAT).MethodsIn this systematic review and meta-analysis, databases including Web of Science, ScienceDirect, PubMed, and Scopus were searched. All studies published in English between 2011 and 2022 that reported the status of nurses' knowledge of PU prevention based on PUKAT were included in the analysis. Based on heterogeneity between the studies, the data were analyzed using a random effects model.ResultsThe pooled scores of PU prevention knowledge in nurses and nursing students were (51.5%; 95% CI: 45.8–57.2%) and (48.9%; 95% CI: 42.5–55.2%), respectively. As the age of the participants increased, the pooled score of pressure ulcer prevention knowledge increased significantly (p = 0.028). The publication bias was not significant. The highest and lowest knowledge scores in nurses and nursing students were related to the fourth dimension (nutrition) and the fifth dimension (preventive measures to reduce the amount of pressure/shear), respectively.ConclusionKnowledge of nurses and nursing students about PU prevention is insufficient. Providing regular training to nurses and including the principles of PU prevention in the curriculum of nursing students to improve their knowledge seems necessary.

Published: September 2022

ObjectiveWe describe the chronological trends in cerebral revascularization surgery through a single-surgeon experience; and we review whether in the context of giant and fusiform cerebral aneurysms, flow-diverting stents have impacted on the use of cerebral revascularization surgery.MethodsWe review our single institution prospectively collected database of cerebral revascularization procedures between 2006 and 2018. Comparing this to our database of flow-diverting endovascular stent procedures, we compare the treatment of fusiform and giant aneurysms. We describe patient demographics, procedural incidence, complications, and outcomes.ResultsBetween 2006 and 2018, 50 cerebral revascularization procedures were performed. The incidence of cerebral revascularization surgery is declining. In the context of giant/fusiform aneurysm treatment, the decline in cerebral revascularization is accompanied by a rise in the use of flow-diverting endovascular stents. Thirty cerebral revascularizations were performed for moyamoya disease and 11 for giant/fusiform aneurysm. Four (14%) direct bypass grafts occluded without neurological sequela. Other morbidity included hydrocephalus (2%), transient ischemic attacks (2%), and ischemic stroke (2%). There was one procedure-related mortality (2%). Flow-diverting stents were inserted for seven fusiform and seven giant aneurysms. Comparing the treatment of giant/fusiform aneurysms, there was no significant difference in morbidity and mortality between cerebral revascularization and flow-diverting endovascular stents.ConclusionWe conclude that with the decline in the incidence of cerebral revascularization surgery, there is a need for centralization of services to allow high standards and outcomes to be maintained.
Detection of Anaplasma phagocytophilum in Ovine Serum Samples—A Retrospective Study
Authors: Rubel Wiebke , Ganter Martin , Bauer Benjamin Ulrich 
Published: September 2022

Tick-borne fever in sheep is caused by Anaplasma phagocytophilum and this obligate intracellular bacterium multiplies mostly in neutrophil granulocytes of its host. In Europe, the pathogen is mainly transmitted by the tick species Ixodes ricinus. Data on the dissemination of A. phagocytophilum in the German sheep population are scarce. Hence, this pilot study aimed to investigate the presence of A. phagocytophilum in ovine serum samples retrospectively. The use of sera is beneficial because the specimens are available in large numbers and usually stored over a long period of time. Ten sheep flocks located in five federal states of Germany (Baden-Württemberg, Bavaria, Lower Saxony, North Rhine-Westphalia, Schleswig-Holstein) were included in the investigations, due to the high intra-flock seroprevalence (>63%) of antibodies against the Anaplasma species. In total, 357 serum samples from seropositive sheep were analysed by 16S rRNA real-time PCR. DNA of A. phagocytophilum was detected in two ewes from the same farm in the northern German federal state of Schleswig-Holstein and represented an overall detection rate of 0.6%. Serum samples can be used to determine A. phagocytophilum, but sensitivity might be reduced in comparison to whole blood samples. Moreover, the sampling time may influence the detection of A. phagocytophilum in sheep, due to the seasonal pattern of tick activity in Germany. Our results support the findings of previous studies and demonstrate that A. phagocytophilum is also present in sheep from northern Germany (Schleswig-Holstein).

Aim. To investigate the incidence and structure of vascular retinal pathologies in women with preeclampsia and its combination with chronic arterial hypertension (AH).Methods. A total of 231 medical records of women with different pregnancy histories were studied by consecutive sampling. The first experimental group comprised women (n = 47) diagnosed with preeclampsia combined with chronic AH. The second experimental group comprised women (n = 48) with preeclampsia developed during pregnancy. The first comparison group included women with pregnancy-associated gestational AH. The second comparison group included women with edema and proteinuria during pregnancy but without AH. The control group consisted of women (n = 50) with normal pregnancy histories. The postpartum period ranged from 6 to 12 years.Results. The development of vascular retinal pathologies during the postpartum period occurred in 28 women in the general sample (12%). Retinal vein occlusions predominated in the structure of vascular retinal pathology (19 women, 19 eyes). Proliferative retinopathy was detected in 8 patients (8 eyes). In one case, a central retinal artery occlusion developed.Conclusions. The incidence of vascular retinal pathologies in the 1st and 2nd experimental groups comprised 21% and 25% respectively, which was statistically significantly higher than that in the control, 1st and 2nd comparison groups (4%, 4%, and 6% respectively, p < 0.01). The revealed significantly higher incidence of vascular retinal pathology in both experimental groups indicates the domineering role of preeclampsia and AH-associated pre-eclampsia in the development of vascular retinal pathologies.
Communication Network Reliability under geographically correlated failures using Probabilistic Seismic Hazard Analysis
Authors: Barrera Javiera , Jiménez-Álvarez Dora , Cancela Héctor 
Published: September 2022

<p>The research community’s attention has been attracted to the reliability of networks exposed to large-scale disasters and this has become a critical concern in network studies during the last decade. Earthquakes are high on the list of those showing the most significant impacts on communication networks, and simultaneously, they are the least predictable events. This study uses the Probabilistic Seismic Hazard Analysis method to estimate the network element state after an earthquake. The approach considers a seismic source model and ground prediction equations to assess the intensity measure for each element according to its location. In the simulation, nodes fail according to the building's fragility curves. Similarly, links fail according to a failure rate depending on the intensity measure and the cable's characteristics. We use the source-terminal, and the diameter constrained reliability metrics. The approach goes beyond the graph representation of the network and incorporates the terrain characteristics and the component's robustness into the network performance analysis at an affordable computational cost. We study the method on a network in a seismic region with almost 9000 km of optical fiber. We observed that for source-terminal that are less than 500 km apart the improvements are marginals while for those that are more than 1000 km apart, reliability improves near a 30\% in the enhanced designs. We also showed that these results depend heavily on the robustness/fragility of the infrastructure, showing that performance measures based only the network topology are not enough to evaluate new designs.</p>

On Completing Partial Latin Squares with Prescribed Diagonals
Authors: Andersen Lars , Baumann Stacie , Hilton Anthony , Rodger Chris 
Published: September 2022

Necessary and sufficient numerical conditions are known for the embedding of an incomplete latin square $L$ of order $n$ into a latin square $T$ of order $t \geq 2n+1$ in which each symbol is prescribed to occur in a given number of cells on the diagonal of $T$ outside of $L$. This includes the classic case where $T$ is required to be idempotent. If $t<2n$ then no such numerical sufficient conditions exist since it is known that the arrangement of symbols within the given incomplete latin square can determine the embeddibility. All examples where the arrangement is a factor share the common feature that one symbol is prescribed to appear exactly once in the diagonal of $T$ outside of $L$, resulting in a conjecture over 30 years ago stating that it is only this feature that prevents numerical conditions sufficing for all $t \geq n$.In this paper we prove this conjecture, providing necessary and sufficient numerical conditions for the embedding of an incomplete latin square $L$ of order $n$ into a latin square $T$ of order $t$ for all $t \geq n$ in which the diagonal of $T$ outside of $L$ is prescribed in the case where no symbol is required to appear exactly once in the diagonal of $T$ outside of $L$.
Density Maximizers of Layered Permutations

Published: September 2022

A permutation is layered if it contains neither $231$ nor $312$ as a pattern.It is known that, if $\sigma$ is a layered permutation, then the density of $\sigma$ in a permutation of order $n$ is maximized by a layered permutation. Albert, Atkinson, Handley, Holton and Stromquist [Electron. J. Combin. 9 (2002), #R5] claimed that the density of a layered permutation with layers of sizes $(a,1,b)$ where $a,b\geq2$ is asymptotically maximized by layered permutations with a bounded number of layers, and conjectured that the same holds if a layered permutation has no consecutive layers of size one and its first and last layers are of size at least two.
We show that, if $\sigma$ is a layered permutation whose first layer is sufficiently large and second layer is of size one, then the number of layers tends to infinity in every sequence of layered permutations asymptotically maximizing the density of $\sigma$. This disproves the conjecture and the claim of Albert et al. We complement this result by giving sufficient conditions on a layered permutation to have asymptotic or exact maximizers with a bounded number of layers.

COVID-19 pandemic has impacted all aspects of our lives including learning. With the particular growth of e-learning, teaching approaches are being implemented at a distance on online platforms due to this pandemic. In this context, to make student involved throughout the online course, it is recommended to create an efficient platform similar to the traditional learning mode. In this study, we aims to improve learning style detection process by exploring additional such as cognitive traits. In fact, we have proposed novel approach based on Artificial neural network that classify students according to their level of cognitive learning styles in real-time. The proposed automated approach will certainly provide tutors with exhaustive information that helps them in achieving an improved and innovative online learning method. The results obtained are quite interesting and demonstrate the relevance of our solution.
Evaluation of Learning Efficiency of Massive Open Online Courses Learners
Authors: Li Yong 
Published: September 2022

This study selected 175 massive open online courses (MOOC) learners of the School of Marxism in a university in Henan Province as respondents. A hierarchical clustering analysis was carried out using SPSS22.0, and the learning styles of learners were classified by k-means clustering. The learning efficiency of learners was estimated by data envelopment analysis (DEA), and the differences of learning styles in learning inputs and learning outputs were analyzed through a variance test. Results demonstrated that according to hierarchical clustering analysis, the learning behavioral indicators of MOOC learners could be divided into four classes. According to the results of k-means clustering, learning styles could be divided into four types, namely, high-input-high-output, high-input-low-output, low-input-high-output, and low-input-low-output. Clustering results could explain significant differences in learning inputs well, thus showing significance (P<0.05). A total of 125 respondents were non-DEA effective, accounting for 71.43%. Moreover, 114 respondents had fixed or increasing returns to scale, accounting for 65.14%. The conclusions of this research are of important significance to analyze the progress effectiveness of students, increase the scientificity and rationality of teaching evaluation theory, train teaching managers to control the teaching effects, and make scientific evaluations of the learning efficiency of university students.
On generation of the coefficient field of a primitive Hilbert modular form by a single Fourier coefficient
Authors: Kumar Narasimha , Sahoo Satyabrat 
Published: September 2022

AbstractLet f be a primitive Hilbert modular form over F of weight k with coefficient field
$E_f$
, generated by the Fourier coefficients
$C(\mathfrak {p}, f)$
for
$\mathfrak {p} \in \mathrm {Spec}(\mathcal {O}_F)$
. Under certain assumptions on the image of the residual Galois representations attached to f, we calculate the Dirichlet density of
$\{\mathfrak {p} \in \mathrm {Spec}(\mathcal {O}_F)| E_f = \mathbb {Q}(C(\mathfrak {p}, f))\}$
. For
$k=2$
, we show that those assumptions are satisfied when
$[E_f:\mathbb {Q}] = [F:\mathbb {Q}]$
is an odd prime. We also study analogous results for
$F_f$
, the fixed field of
$E_f$
by the set of all inner twists of f. Then, we provide some examples of f to support our results. Finally, we compute the density of
$\{\mathfrak {p} \in \mathrm {Spec}(\mathcal {O}_F)| C(\mathfrak {p}, f) \in K\}$
for fields K with
$F_f \subseteq K \subseteq E_f$
.
