Awareness of different forms of child abuse among Beni Suef University students: descriptive survey
Authors: Welson Nermeen N. , Mohamed Yasmen A.
Published: December 2019

Background

Child abuse is a worldwide phenomenon that can cause intense long-term aftereffects.

Aim

To evaluate the awareness of Beni Suef University students about different forms of child abuse as well as the size, causes, and complications of this problem in our society and determine the prevalence of physical child abuse.

Methods

The study included 1688 students from health science and non-health science colleges of Beni Suef University, Egypt. The study participants were asked to answer a questionnaire of two parts. The first part included questions about demographic data and personal experience of child abuse, and the second part included questions about opinions of participants on child abuse to assess their awareness and if there was any difference in the level of awareness between students of health science colleges and those of non-health science colleges.

Results

Health science college students were more life satisfied and felt more loved. Only 28.91% of the included students were not exposed to child abuse, while 12.59% of them suffered from wounds or fractures as a result of the abuse they were exposed to. About one third of the students thought that the commonest form of child abuse is verbal punishment such as threatening or humiliation and that the age at the greatest risk for abuse was the primary school age. About 68.36% of students thought that sexual abuse is a huge problem in our society. Only 21.56% of students disapproved child corporal punishment. More than half of the students stated that the most dangerous complication of child abuse is psychological problems such as depression. Most of the included students would talk to the child’s parents and advise them if they saw a case of abuse, while the least would call the police. Only half of the students disapproved female genital mutilation (FGM). The strongest predictive factors for FGM approval were rural residence and male sex. Students mainly thought that FGM is a social habit that is carried out for ethical causes. About half of the students approved legal punishment by the court for FGM performers.

Conclusion

A significant proportion of the students experienced physical child abuse which left no injuries in most cases; males and first academic year students show more exposure to abuse. Moreover, most of the students think that child corporal punishment can be allowed although about half of them think that the most dangerous aftereffect of child abuse is psychological problems. Lack of reporting the exposure to child abuse is explained by the largest percentage of students to be due to lack of awareness. Rural resident males show more approval of female genital mutilation. A significant lack of awareness about FGM complications is observed in both groups (the health science and non-health science college groups) and the opinions of both groups are very close.
Interaction between Fusarium head blight and crown rot disease incidence and cultural practices on wheat in the south of Iraq, Basra province
Authors: Minati Mohammed Hussein , Mohammed-Ameen Mohaned Khalaf
Published: December 2019

Background

This study was conducted to estimate Fusarium head blight (FHB) and crown rot (FCR) disease incidence on wheat and their interaction with cultural methods (cultivar types, planting time, seed rate, crop rotation, and fertilizer practices) that are used in wheat cropping system in the south of Iraq, Basra province.

Results

The results showed that the mean average of FHB and FCR was 27.2% and 31%, respectively. This displays that very nearly one-third of wheat crop planted in those 14 fields were infected by both diseases but not very severely, except in two fields (D and HM), which were devastating, 54% and 71% and 41% and 52% for FHB and FCR, respectively. The highest level of incidence for both diseases was associated with the earlier and latest planting dates 28 Oct. and 10 Dec., while the lowest was with 1, 10, and 23 Nov. A 200 and 120 kg/ha were the highest and lowest seed rates used in this study. The selected wheat fields differed in their pre-crop rotations (legume, corn, sorghum, okra, and continuous cropping system of wheat) in a previous year. The amount of added fertilizers (urea, DAP, and NPK) to the studied fields was in a high variation. The seven wheat cultivars examined in this study showed different levels of susceptibility to both diseases.

Conclusion

The results verified that most of the agricultural practices examined in this study were associated with positive correlation for FHB and FCR in the occurrence of disease incidence. Except the cultivar type and fertilizer application had unclear relationship with the incidence of both diseases.

Published: December 2019

The bollworm can be controlled effectively with Bacillus thuringiensis transgenic cotton (Bt cotton) which is being applied worldwide. However, the insecticidal efficacy is not stable. Here we give a summary of research progress for the mechanism of the altered insecticidal efficacy, factors affecting the expression of insect resistance, agronomic practices on regulation of insecticidal efficacy in Bt cotton. To realize the transgenic potential of Bt cotton cultivars, future research may be conducted by increasing synthesis and reducing degradation of Bt protein to maintain high insecticidal ability in the transgenic cotton by agronomic management.
The Incretin Effect in Female Mice With Double Deletion of GLP-1 and GIP Receptors
Authors: Ahrén Bo , Yamada Yuichiro , Seino Yutaka
Published: December 2019

To establish the contribution of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) for the incretin effect after oral glucose, studies were undertaken in female mice with genetic deletion of receptors for GIP and GLP-1 (double incretin receptor knockout [DIRKO] mice) and their wild-type (WT) counterparts. Insulin secretion was explored after oral glucose (doses ranging from 0 to 100 mg), after intravenous glucose (doses ranging from 0 to 0.75 g/kg), and after oral and intravenous glucose at matching circulating glucose. DIRKO mice had glucose intolerance after oral glucose challenges in association with impaired beta-cell function. Suprabasal area under the curve for C-peptide (AUCC-peptide) correlated linearly with suprabasal AUCglucose both in WT (r = 0.942, P = .017) and DIRKO mice (r = 0.972, P = .006). The slope of this regression was lower in DIRKO than in WT mice (0.012 ± 0.006 vs 0.031 ± 0.006 nmol C-peptide/mmol glucose, P = .042). In contrast, there was no difference in the insulin response to intravenous glucose between WT and DIRKO mice. Furthermore, oral and intravenous glucose administration at matching glucose levels showed that the augmentation of insulin secretion after oral glucose (the incretin effect) in WT mice (11.8 ± 2.3 nmol/L min) was entirely absent in DIRKO mice (3.3 ± 1.2 nmol/L min). We conclude that GIP and GLP-1 are required for normal glucose tolerance and beta-cell function after oral glucose in mice, that they are the sole incretin hormones after oral glucose at higher dose levels, and that they contribute by 65% to insulin secretion after oral glucose.
Extreme blood boosting capacity of an Antarctic fish represents an adaptation to life in a sub-zero environment

Published: December 2019

Blood doping, the practice of boosting the oxygen carrying capacity of blood, is an illegal strategy used by human athletes to enhance aerobic capacity and athletic performance. Interestingly, the practice of boosting blood oxygen carrying capacity is also naturally prevalent in the animal kingdom via the splenic release of stored erythrocytes. Here we demonstrate that an Antarctic notothenioid fish, the bald notothen (Pagothenia borchgrevinki), is a master of this practice. Due to the sub-zero environment these fish inhabit, they sequester a large proportion of erythrocytes in the spleen during times of inactivity to reduce the energetic and physiological costs associated with continuously pumping highly viscous blood around the body. However, in response to metabolically demanding situations (i.e. exercise and feeding), these fish contract the spleen to eject stored erythrocytes into circulation, which boosts blood oxygen carrying capacity by up to 207% (c.f. exercise-induced increases of ∼40-60% in a range of other vertebrates and ∼5-25% in blood-doping athletes). By evaluating cardiorespiratory differences between splenectomized (unable to release erythrocytes from the spleen) and sham-operated individuals, we demonstrate the metabolic benefits (i.e. aerobic scope increased 103%) and the cardiovascular trade-offs (i.e. ventral aortic blood pressure and cardiac workload increased 12% and 30%, respectively) associated with the splenic blood boosting strategy. In conclusion, this strategy provides bald notothens with an extraordinary facultative aerobic scope that enables an active lifestyle in the extreme Antarctic marine environment, while minimizing the energetic and physiological costs of transporting highly viscous blood during times of reduced energetic demand.
Frogs seek hypoxic microhabitats that accentuate metabolic depression during dormancy

Published: December 2019

Many animals occupy microhabitats during dormancy where they may encounter hypoxic conditions (e.g. subterranean burrows). We used the green-striped burrowing frog (Cyclorana alboguttata) to test the hypothesis that animals seek hypoxic microhabitats that accentuate metabolic depression during dormancy. We first measured the partial pressure of oxygen (pO2) within artificial cavities excavated in wet clay soil, which simulated C. alboguttata underground aestivation chambers, and recorded hypoxic conditions (pO2 as low as 8.9 kPa). Using custom-built tunnels that maintained a longitudinal pO2 gradient (hypoxic to normoxic), we then examined the pO2 preference of C. alboguttata in response to drying habitat conditions. In support of our hypothesis, we found that C. alboguttata chose to spend a greater proportion of time at the hypoxic end of the pO2 gradient compared to the normoxic end. To determine if hypoxia accentuates metabolic depression in C. alboguttata, we exposed frogs to normoxia (21.0 kPa) or hypoxia (10.5 kPa) for 7 weeks during the transition from an active to aestivating state. We found that hypoxia exposure accelerated the onset of metabolic depression in C. alboguttata by 2 weeks. Furthermore, we found that frogs exposed to hypoxia exhibited a 66% reduction in O2 consumption after 7 weeks compared to active frogs in normoxia, whereas frogs exposed to normoxia reduced O2 consumption by only 51%. Overall, our findings indicate that some animals may seek microhabitats to maximally depress metabolic rate during dormancy, and that microhabitat O2 availability can have significant implications for energy metabolism.
vhcub: Virus-host codon usage co-adaptation analysis
Authors: Anwar Ali Mostafa , Soudy Mohamed , Mohamed Radwa
Published: December 2019

Viruses show noticeable evolution to adapt and reproduce within their hosts. Theoretically, patterns and factors that affect the codon usage of viruses should reflect evolutionary changes that allow them to optimize their codon usage to their hosts. Some software tools can analyze the codon usage of organisms; however, their performance has room for improvement, as these tools do not focus on examining the codon usage co-adaptation between viruses and their hosts. This paper describes the vhcub R package, which is a crucial tool used to analyze the co-adaptation of codon usage between a virus and its host, with several implementations of indices and plots. The tool is available from: https://cran.r-project.org/web/packages/vhcub/.
Sparse Travel Time Estimation from Streaming Data
Authors: Jabari Saif Eddin , Freris Nikolaos M. , Dilip Deepthi Mary
Published: December 2019

We address two shortcomings in online travel time estimation methods for congested urban traffic. The first shortcoming is related to the determination of the number of mixture modes, which can change dynamically within a day and from day to day. The second shortcoming is the widespread use of Gaussian probability densities as mixture components. Gaussian densities fail to capture the positive skew in travel time distributions, and consequently, large numbers of mixture components are needed for reasonable fitting accuracy when applied as mixture components. They also assign positive probabilities to negative travel times. To address these issues, this paper derives a mixture distribution with Gamma component densities, which are asymmetric and supported on the positive numbers. We use sparse estimation techniques to ensure parsimonious models and propose a generalization of Gamma mixture densities using Mittag–Leffler functions that provides enhanced fitting flexibility and improved parsimony. In order to accommodate within-day variability and allow for online implementation of the proposed methodology (i.e., fast computations on streaming travel time data), we introduce a recursive algorithm that efficiently updates the fitted distribution whenever new data become available. Experimental results using real-world travel time data illustrate the efficacy of the proposed methods.

Published: December 2019

A worldwide investigation is being carried out for improving the photoconversion efficiency of solar cells. Among all solar cells, quantum dots solar cell (QDSC) has proven as the best potential for photocurrent generator. The major focus of this research work is comparing the performance of QD based solar cells with and without the addition of synthesized dielectric nanomaterials for reducing recombination problems and higher the exciton generation. The selection of dielectric nanomaterial was carried out based on their good field-effect passivation, screened columbic attraction, enactment as a back reflector, and recombination inhibitor in solar cell. According to the above-mentioned factors lanthanum doped lead titanate Pb0.85La0.15TiO3 (PLT15) is a promising material for this research work. For improving the performance of QD based solar cells, the PLT15 paired mesoporous TiO2 electron transport layer (ETL) film was deposited onto fluorine-doped tin oxide (FTO) coated glass substrate using doctor blading technique followed by annealing the QD deposition onto the coated glass substrate was carried out via dipping of the glass into the QD solution for overnight. The QD used in this research work were namely – PbI3. Finally, the performance study was carried out which indicates that the introduction of dielectric material into the QDSC has proven to be as innovative and as well as efficient for improving the photocurrent conversion efficiency.

Published: December 2019

In this paper, a compact optical high-speed 1-bit comparator is proposed based on photonic crystals. In this structure, the nonlinear rods are used at the cross-connecting point of two optical waveguides. The optical transmission and reflection from these rods depend on the amount of the optical intensity. In response to the different states of the input ports, different values of the optical power reach these rods and the interference patterns make the correct function of the output ports. The refractive index and the Kerr coefficient of nonlinear rods are

Authors: Zhou Jianyu , Cheng Xinbin , Zhang Jinlong , Jiao Hongfei , Zhang Zhanyi , Li Haoran , Wang Zhanshan
Published: December 2019

A dual-channel two-dimensional (2D) reflection grating filter operating around the 1.55 µm wavelength region is demonstrated, exhibiting dual-channel reflection peaks at 1.492 µm and 1.647 µm. The sidebands intrinsic to this kind of grating are suppressed by appropriately designed antireflective thin films, and this can be proved by equivalent medium theory. Using the modal analysis method, the excitation modes of the dual-channel reflection peaks are determined to be the TM0 (1.490 µm) and TE0 (1.638 µm) modes. The estimated relative errors in the wavelength determination of these modes are less than 1%. This is found to be in accord with analyses of the reflectivity spectra and electromagnetic fields. The dual-channel reflection peaks are sensitive to the background refractive index and may be useful in biosensing applications.

Published: December 2019

Intrinsic radiosensitivity is a biological parameter known to influence the response to radiation therapy in cancer treatment. In this study, Raman spectroscopy and surface enhanced Raman spectroscopy (SERS) were successfully used in conjunction with principal component analysis (PCA) to discriminate between radioresistant (LY-R) and radiosensitive (LY-S) murine lymphoma sublines (L5178Y). PCA results for normal Raman analysis showed a differentiation between the radioresistant and radiosensitive cell lines based on their specific spectral fingerprint. In the case of SERS with gold nanoparticles (AuNPs), greater spectral enhancements were observed in the radioresistant subline in comparison to its radiosensitive counterpart, suggesting that each subline displays different interaction with AuNPs. Our results indicate that spectroscopic and chemometric techniques could be used as complementary tools for the prediction of intrinsic radiosensitivity of lymphoma samples.

Los saberes de la historia política en la residencia docente: del discurso a la práctica
Authors: Campilia Mariano Luis , Druetta Matías Nicolás
Published: December 2019

Compartimos avances de investigación donde nos preguntamos acerca de los saberes de la historia política que ponen en juego los practicantes durante la residencia docente. Es decir, cuáles son los posicionamientos teóricos que asumen al elaborar su propuesta de enseñanza y de qué manera se expresan en la práctica. Indagamos acerca de la enseñanza del pasado histórico desde la perspectiva de la Nueva Historia Política buscando reconocer y poner en tensión los alcances y limitaciones que presentan las propuestas respecto a esta dimensión particular del conocimiento histórico.

Al pensar qué, cómo y para qué enseñar, los residentes ponen en juego enfoques teórico-metodológicos. Pretendemos en ese sentido, visibilizar los acercamientos, tensiones y/o distanciamientos entre los supuestos teóricos y sus prácticas.

En este sentido, buscamos dar respuesta a los siguientes interrogantes: ¿qué vínculos se establecen con el pasado desde la dimensión política? ¿Cómo se trabaja la dominación, el poder, el conflicto, las resistencias, la intervención en el espacio público, la relación Estado-sociedad civil, los actores sociales, etc.?

Experiencias didácticas en el nivel superior sobre el tratamiento de la temporalidad en clases de historia medieval y moderna
Authors: Andelique Carlos Marcelo , Tonon María Cecilia
Published: December 2019

Aunque el tiempo histórico es una categoría epistemológica fundamental para explicar los procesos históricos, generalmente se suele dar por sentado que los alumnos lo comprenden por el sólo hecho de leer y estudiar textos historiográficos. Sin embargo, las dificultades que presentan los estudiantes en el Profesorado y Licenciatura en Historia de la Facultad de Humanidades y Ciencias de la UNL al momento de utilizar las categorías temporales nos confirman la necesidad de un abordaje más sistemático de la temporalidad en la clase de historia. En función de la experiencia realizada en las clases de Sociedades Medievales y Formación del Mundo Moderno I, en este trabajo nos proponemos, a partir de nociones básicas sobre el tiempo y sus relaciones con la historia, describir y analizar actividades, recursos y materiales implementados en diferentes clases sobre determinados acontecimientos y procesos históricos de las sociedades medievales y la modernidad temprana. Las fuentes principales en este trabajo son las diferentes representaciones gráficas temporales que se han elaborado para enseñar distintos temas de las asignaturas mencionadas, su desarrollo metodológico y la recepción que tuvieron las actividades y materiales por parte de los estudiantes.

Published: December 2019

El texto explora las discusiones en torno a la propuesta curricular del BNCC 2015 que condujo a una ruptura con el paradigma eurocéntrico en la enseñanza del contenido de historia al proponer un enfoque atlántico. Se propone reflexionar sobre la forma en que la idea de la historia atlántica, aunque aún esbozada, se puso en práctica en el primer ataque de la organización curricular desde esta perspectiva y provocó una ruptura efectiva con el paradigma eurocéntrico, tan arraigado en la organización curricular en el sistema educativo brasileño. El análisis se realizó consultando el documento oficial y los textos producidos por asociaciones de docentes, grupos de investigación y académicos debido al controvertido debate público / académico establecido y la literatura especializada.

Adult hippocampal neurogenesis (AHN) is suppressed by high-fat (HF) diet and metabolic disease, including obesity and type 2 diabetes. Deficits in AHN may contribute to cognitive decline and increased risk of dementia and mood disorders, which have higher prevalence in women. However, sex differences in the effects of HF diet/metabolic disease on AHN have yet to be thoroughly investigated. Herein, male and female C57BL/6J mice were fed an HF or control (CON) diet from ∼2 to 6 months of age. After 3 months on the diet, mice were injected with 5-ethynyl-2′-deoxyuridine (EdU) then killed 4 weeks later. Cell proliferation, differentiation/maturation, and survival of new neurons in the dentate gyrus were assessed with immunofluorescence for EdU, Ki67, doublecortin (DCX), and NeuN. CON females had more proliferating cells (Ki67+) and neuroblasts/immature neurons (DCX+) compared with CON males; however, HF diet reduced these cells in females to the levels of males. Diet did not affect neurogenesis in males. Further, the numbers of proliferating cells and immature neurons were inversely correlated with both weight gain and glucose intolerance in females only. These effects were robust in the dorsal hippocampus, which supports cognitive processes. Assessment of microglia in the dentate gyrus using immunofluorescence for Iba1 and CD68 uncovered sex-specific effects of diet, which may contribute to observed differences in neurogenesis. These findings demonstrate sex-specific effects of HF diet/metabolic disease on AHN, and highlight the potential for targeting neurogenic deficits to treat cognitive decline and reduce the risk of dementia associated with these conditions, particularly in females.

Rennin-angiotensin system (RAS) has been involved in sperm function, even so, little is known about the implication of one of the RAS axis formed by Ang-(1–7) (angiotensin-(1–7)) and MAS receptor. Hence, in the present work, we focused on elucidating the function of the MAS receptor in human spermatozoa. We analyzed the expression and localization of MAS receptor in human spermatozoa and we observed if its activation is able to modulate the sperm motility of normal motility and/or asthenozoospermic patients, as well as, the acrosome reaction of the spermatozoa. MAS receptor is present in human mature spermatozoa, not only at the mRNA level but also at protein level. MAS is localized at the acrosome region, as well as, in the tail of spermatozoa. The sperm incubation with MAS agonist Ang-(1–7) activates at dose-dependent manner the PI3K/AKT pathway (P < 0.01 vs control) and improves the motility of asthenozoospermic patients (P < 0.01 vs control), which is blocked by the specific antagonist (A779) (P < 0.01), but it do not modulate the acrosome reaction. These findings suggest that the ACE2/Ang-(1–7)/Mas axis may be a useful biochemical tool for the treatment of male infertility related to sperm mobility.

Published: December 2019

This paper develops a systematic method for calculating approximate prices for a wide range of securities implying the tools of spectral analysis, singular and regular perturbation theory. Price options depend on stochastic volatility, which may be multiscale, in the sense that it may be driven by one fast-varying and one slow-varying factor. The found the approximate price of two-barrier options with multifactor volatility as a schedule for own functions. The theorem of estimation of accuracy of approximation of option prices is established. Explicit formulas have been found for finding the value of derivatives based on the development of eigenfunctions and eigenvalues of self-adjoint operators using boundary-value problems for singular and regular perturbations. This article develops a general method of obtaining a guide price for a broad class of securities. A general theory of derivative valuation of options generated by diffusion processes is developed. The algorithm of calculating the approximate price is given. The accuracy of the estimates is established. The theory developed is applied to a diffusion operator, which is decomposed by eigenfunctions and eigenvalues. The purpose of the article is to develop an algorithm for finding the approximate price of two-barrier options and to find explicit formulas for finding the value of derivatives based on the development of self-functions and eigenvalues of self-adjoint operators using boundary-value problems for singular and regular perturbations. Price finding is reduced to the problem solving of eigenvalues and eigenfunctions of a certain equation. The main advantage of our pricing methodology is that, by combining methods in spectral theory, regular perturbation theory, and singular perturbation theory, we reduce everything to equations to find eigenfunctions and eigenvalues.

The paper analyses various scientific approaches to the interpretation of the essence of the concept of “personnel management”, defines the specific characteristics and principles of this process. For a detailed study of the essence and content of the concept of the personnel management, theoretical approaches to this definition and substantiation of its content in the context of various scientific schools and management theories are analysed. Scientific approaches to understanding the functional role and essence of the personnel management in various scientific schools are analysed, namely: schools of scientific management, classical (administrative) school of management, theory of perfect bureaucracy, school of human relations, empirical school of management, school of social systems, and “new school”.

The main differences in understanding the process of the personnel management in different theories of management are investigated, the main of which are: situational management theory; system theory of management; theory of organizational culture; theory of human resources management; theory of management culture. The relationship scheme and the place of the personnel management system in the enterprise management in general are substantiated. A three-level personnel management system for tactical, operational and ongoing tasks is proposed. The mechanism of organizational and economic support of the personnel management as a system of synergistically interconnected organizational and economic factors for establishing high-performance HR-management in the enterprise is substantiated. The main elements of organizational and economic support for improving the personnel management system of enterprises are scientific and theoretical approaches to the forming of this system; principles of personnel management; methods of labour management; functions of HR-management; economic levers; methodological support; information support; monitoring of personnel management.
Instructional Practices of High School Religion Teachers
Authors: Zoeller Adam , Malewitz Thomas
Published: December 2019

With many of the Catholic student population disengaged from regular
ritual experiences their working vocabulary of the prayers and knowledge of
the Church is limited. A beneficial bridge for many of these disconnected
students, specifically male adolescents has been the use of storytelling in
connection to Catholic themes to lay the foundations of ritual and deeper
concepts through a more familiar setting. Through media literary,
multi-modal instruction and Scripture exegesis adolescents can begin to
recognize, understand, and feel a connection with the severity of the
sacrifice of the Apostles in following Jesus of Nazareth. This article will
offer some insights that have proven to be beneficial to help male
adolescents to engage the complicated and foreign concepts and topics of the
new curriculum framework, in association with Peter Jackson’s vision of
Tolkien’s Fellowship of the Ring.
Teaching While Praying, Praying While Teaching: An Interactional
Sociolinguistics of Educational Prayer
Authors: LeBlanc Robert Jean
Published: December 2019

What are the linguistic resources for teachers who pray in contemporary
Catholic school classrooms? This article considers the intersections of
prayer and language practice, and I make central two arguments. The first is
that educational prayer—a particular type of teacher-led extemporaneous
prayer in Catholic schools—is a linguistic phenomenon, a highly-flexible set
of linguistic resources, captured within a special interactional frame
marked by ambiguous boundaries which contains both prescribed formulaic
linguistic properties and those which allow the performer to attend to real
time classroom contingencies. Drawing on interactional data from a Catholic
school classroom, this article delimits the contextualization of linguistic
signs during prayer: how teachers indicate the connection between their
words and the sociocultural frameworks which are relevant for that action.
The second is that both interactional sociolinguists and Catholic school
researchers would greatly benefit from attending to these linguistic
features, from seeing prayer unfold in real-time.
Seminarian Sentiments About Catholic Schools
Authors: Calkins Kevin , Convey John
Published: December 2019

Three hundred sixty-one seminarians from the 48 diocesan seminaries in
the United States and the North American College in Rome, Italy responded to
a survey regarding their sentiments about the value of Catholic schools,
their effectiveness, and the importance of financially supporting them. The
results suggest that while diocesan seminarians are generally supportive of
Catholic schools, they are more positive about the value of Catholic schools
and the importance of providing financial support than they are about the
effectiveness of Catholic schools, especially their religious effectiveness.
The seminarians’ sentiments toward value and financial support are
comparable to those of previous studies of priests. The seminarians’ own
backgrounds in Catholic schools, selection of the most important purpose of
Catholic schools, age, Hispanic ethnicity, and whether the seminary provided
academic instruction about Catholic schools are factors that influenced
their sentiments, particularly of effectiveness. The study did not include
seminarians from religious congregations.
Can an authentic EPortfolio succeed in First Year Medicine?
Authors: Grom Iain , O'Neill Anna
Published: December 2019

This article was migrated. The article was not marked as recommended. IntroductionDespite evidence supporting ePortfolio use to promote reflective practice, most published studies focus on its use in senior years. This study explored how well the introduction of the Undergraduate Medical ePortfolio (UMeP) in Year 1 of an early clinical contact curriculum met its aims of supporting reflective practice and introducing portfolio learning. Effective mentoring, organisational support, authenticity and adequate time are key to success. MethodsA constructivist study heard the voices of students n=14 (2 focus groups) and tutors n=6 (semi-structured interviews) who had used the UMeP in its first introductory year. Thus, triangulation was employed to gain a deeper appreciation.ResultsAnalysis uncovered four major themes-Reflective Practice , Support/Training , ePortfolio functions,and Feedback/Assessment . The study revealed support for the introduction of portfolio learning in Year 1 Medicine, for its role in promoting reflective practice and for maintaining formative assessment.DiscussionEPortfolio introduction in Year 1 provided a valuable early introduction to reflection and life-long-learning habits. Regular small group tutor support and feedback were positive factors. The study revealed a need for tutor training on reflection feedback. Introduced at a stage without the weight of clinical commitments, this ePortfolio's limited demands allowed students time to learn and become accustomed to its requirements. Scaffold boxes in ePortfolio forms facilitated reflective writing. Use of an authentic portfolio linked to a professional version was a key engagement factor. Through sharing submissions students learned from each other about reflective writing and confidentiality. Better curriculum integration is needed to develop its potential.
Microsurgical treatment of distal aneurysms of the posterior inferior cerebellar artery
Authors: Dashyan V. G. , Senko I. V.
Published: December 2019

The study objective is to analyze characteristics of distal aneurysms of the posterior inferior cerebellar artery (PICA) using the results of surgical treatment of 11 patients with this disorder.

Materials and methods. Eleven patients with distal PICA aneurysms (7 men and 4 women aged between 32 and 57 years (mean age 44 years)) were operated in N.V. Sklifosovsky Research Institute for Emergency Medicine. Aneurysms were visualized using cerebral angiography in 2 patients and using computed angiography in 9 patients. The aneurysms were classified using the classification system developed by J.R. Lister and A.L. Rhoton. Aneurysms located in the tonsillomedullary segment were most common. Saccular aneurysms were found in 7 (64 %) patients, whereas fusiform aneurysms were observed in 4 (36 %) patients. Two saccular aneurysms had a large neck. The size of aneurysms varied between 2 and 9 mm. The majority of patients (70 %) had aneurysms less than 7 mm.

Results. Five patients were operated via median suboccipital approach, while the remaining 6 patients were operated via lateral suboccipital approach. We performed either reconstructive (n = 9) or deconstructive (n = 2) aneurysm clipping depending on the possibility of preserving the PICA lumen and presence of damage to the perforating arteries of the brain stem. Nine patients (82 %) had Glasgow Outcome Score of 5; two patients (18 %) died (one of them was admitted in sopor with occlusive hydrocephalus; another one had grade III–IV obesity and developed purulent septic respiratory complications and secondary purulent meningitis). Two patients (18 %) developed dysarthria and dysphagia in the postoperative period, but these symptoms disappeared by the moment of discharge.

Conclusion. Distal PICA aneurysms are quite rare and require tailored approach to treatment. A surgeon should bear in mind specific anatomical characteristics of aneurysms, control arterial patency when isolating the aneurysm from the bloodstream, and use revascularizing methods whenever possible. In addition to that, a surgeon should be extremely careful during manipulations with perforating arteries of the brain stem and distal cranial nerves, because their damage result in a more difficult postoperative period.

Authors: Bushkov F. A. , Bzhylyanskiy M. A. , Kordonskiy A. Yu.
Published: December 2019

The objective of the present article is to describe a rare clinical case of progressive post-traumatic cervical syringomyelia after spinal cord injury with fracture of proximal metaepiphysis of the right humerus. The patient had a progressive neurological loss after spinal cord injury.

Materials and methods. The patient underwent surgical treatment: decompression and stabilization of spinal column, surgical technique of spinal cord detethering, cyst shunting.

Results. In the postoperative period the patient had increased spasticity in the lower extremities, increased weakness in the muscles of the upper extremities, aggravation of orthostatic hypotension, and inability to flex the first and the fifth fingers of the right hand. Magnetic resonance imaging of the cervical spine revealed progression of syringomyelia.

Conclusion. This case demonstrates differentiation between cervical myelopathy and plexus paresis in a patient with combination spinal injury and reveals the mechanisms underlying late progression of neurological deficit.

Conflict of interest. The authors declare no conflict of interest.
