Μαθητές με αποκλίνουσες συμπεριφορές στο σχολείο
Authors: Τσομπόλη Ειρήνη 
Published: August 2020

Η αποκλίνουσα συμπεριφορά των μαθητών ταλανίζει ολοένα και περισσότερο την εκπαιδευτική κοινότητα και τα τελευταία έτη έχει εντατικοποιηθεί η επιμόρφωση των εκπαιδευτικών, που αφορά τα προγράμματα πρόληψης και παρέμβασης της σχολικής βίας και οφείλεται στις αποκλίνουσες συμπεριφορές. Η εκδήλωση αποκλίνουσας συμπεριφοράς εμφανίζεται σε παιδιά όλο και μικρότερης ηλικίας, φαινόμενο εξαιρετικά ανησυχητικό που πρέπει να απασχολήσει όλη την κοινωνία και όχι μόνο τους εκπαιδευτικούς φορείς. Η παρούσα εργασία έχει ως στόχο να παρουσιάσει τα χαρακτηριστικά των μαθητών με αποκλίνουσα συμπεριφορά, να προσδιορίσει τα αίτια και να αναφέρει τρόπους πρόληψης και αντιμετώπισης των εν λόγω συμπεριφορών. Η συγγραφή της εργασίας μου στηρίχτηκε στην αναζήτηση βιβλίων και ερευνών στο διαδίκτυο, οι οποίες περιείχαν μεγάλα δείγματα συμμετεχόντων. Αποκλείσθηκαν πιλοτικές και πειραματικές έρευνες. Τα προγράμματα παρέμβασης που βασίζονται στο συμπεριφορισμό και τη μίμηση προτύπων είναι αποτελεσματικότερα στις πρώτες τάξεις του δημοτικού, ενώ για μεγαλύτερες βαθμίδες οι πιο αποτελεσματικές μέθοδοι βασίζονται στην εμπλοκή των εφήβων, στη διαπραγμάτευση και τη λήψη αποφάσεων με τη συναίνεση όλων των μαθητών. Τα προγράμματα πρόληψης ωστόσο, βοηθούν τους μαθητές να μην εκδηλώνουν αποκλίνουσες συμπεριφορές, καλλιεργώντας ένα θετικό και υποστηρικτικό κλίμα για τις ανάγκες των μαθητών.

Published: August 2020

Background: Patients with resectable pancreatic ductal adenocarcinoma (PDAC), undergoing adjuvant chemotherapy can experience an array of complications including fatigue, pain and the loss of physical function. Accumulating evidence from largely early stage breast cancer studies supports exercise as an adjunct therapy to help mitigate treatment complications. However, there is a lack of evidence of its feasibility in pancreatic cancer. The purpose of this study is to explore the initial feasibility of delivering a supervised, individualized, and progressive concurrent exercise intervention to individuals with resectable PDAC who are undergoing adjuvant therapy. Methodology: Ten patients with resectable PDAC undergoing adjuvant chemotherapy will be recruited. Clinical care teams will screen patients against inclusion criteria to determine eligibility. All enrolled participants will complete a 16-week, supervised, tailored, moderate intensity exercise intervention consisting of aerobic and muscle strengthening activities. The primary outcome will be feasibility of delivering a supervised exercise intervention. Secondary outcomes will include measures of physical fitness, fatigue, and quality of life. Outcomes will be measured at baseline (T1), 16 weeks (T2) and 3 months post intervention (T3). The feasibility, acceptability and potential utility of the supervised exercise intervention will be explored qualitatively through semi-structured interviews with key stakeholders (e.g. active participants, eligible participants that declined participation and the research staff including exercise physiologists and recruiting clinicians). The use of health and social care services, medications and personal expenses incurred during the trial will also be used to determine cost-effectiveness of this intervention and a potential further RCT in PDAC. Discussion: The overall aim of this study is to determine the utility of a supervised, tailored, moderate intensity exercise intervention in PDAC patients undergoing adjuvant chemotherapy. This feasibility study will help inform the design of future randomised controlled trials to determine the efficacy of the exercise intervention in PDAC.
Burden of disease due to hip, knee, and unspecified osteoarthritis in the Peruvian social health insurance system (EsSalud), 2016
Authors: Araujo-Castillo Roger V. , Culquichicón Carlos , Solis Condor Risof 
Published: August 2020

Introduction: Since its introduction by the World Health Organization (WHO), the concept of burden of disease has been evolving. The current method uses life expectancy projected to 2050 and does not consider age-weighting and time-discounting. Our aim is to estimate the burden of disease due to hip, knee, and unspecified osteoarthritis using this new method in the Peruvian Social Health Insurance System (EsSalud) during 2016. Methods: We followed the original 1994 WHO study and the current 2015 Global Burden of Disease (GBD) methods to estimate disability adjusted life years (DALY) due to osteoarthritis, categorized by sex, age, osteoarthritis type, and geographical area. We used disability weights employed by the Peruvian Ministry of Health, and the last update issued by WHO. Results: Overall, EsSalud reported 17.9 new cases of osteoarthritis per 1000 patients per year. Annual incidence was 23.7/1000 among women, and 72.6/1000 in people above 60 years old. Incidence was 5.6/1000 for knee osteoarthritis and 1.1/1000 for hip. According to the 1994 WHO method, there were 399,884 DALYs or 36.6 DALYs/1000 patients per year due to osteoarthritis. 12.4 and 2.2 DALYs/1000 patients per-year were estimated for knee and hip osteoarthritis, respectively. Using the 2015 GBD method, there were 1,037,865 DALYs or 94.9 DALYs/1000 patients per year. 31.4 and 5.3 DALYs/1000 patients per year were calculated for knee and hip osteoarthritis, respectively. Conclusions: In the Peruvian social health insurance subsystem, hip, knee, and unspecified osteoarthritis produced a high burden of disease, especially among women and patients over 60. The 2015 GBD methodology yields values almost three times higher than the original recommendations.

Background: Maternal and perinatal Health Research collaboration, India (MaatHRI) is a research platform that aims to improve evidence-based pregnancy care and outcomes for mothers and babies in India, a country with the second highest burden of maternal and perinatal deaths. The objective of this paper is to describe the methods used to establish and standardise the platform and the results of the process. Methods: MaatHRI is a hospital-based collaborative research platform. It is adapted from the UK Obstetric Surveillance System (UKOSS) and built on a pilot model (IndOSS-Assam), which has been extensively standardised using the following methods: (i) establishing a network of hospitals; (ii) setting up a secure system for data collection, storage and transfer; (iii) developing a standardised laboratory infrastructure; and (iv) developing and implementing regulatory systems. Results: MaatHRI was established in September 2018. Fourteen hospitals participate across four states in India – Assam, Meghalaya, Uttar Pradesh and Maharashtra. The research team includes 20 nurses, a project manager, 16 obstetricians, two pathologists, a public health specialist, a general physician and a paediatrician. MaatHRI has advanced standardisation of data and laboratory parameters, real-time monitoring of data and participant safety, and secure transfer of data. Four observational epidemiological studies are presently being undertaken through the platform. MaatHRI has enabled bi-directional capacity building. It is overseen by a steering committee and a data safety and monitoring board, a process that is not normally used, but was found to be highly effective in ensuring data safety and equitable partnerships in the context of low and middle income countries (LMICs). Conclusion: MaatHRI is the first prototype of UKOSS and other similar platforms in a LMIC setting. The model is built on existing methods but applies new standardisation processes to develop a collaborative research platform that can be replicated in other LMICs.
Management of postoperative bleeding in surgically debrided wounds: topical haemostat versus electrocautery

Published: August 2020

Objective: To compare the effectiveness of a temporary topical external haemostat (OMNI-STAT Granules, Omni-stat Medical Inc., US) versus the use of electrocautery for bleeding control in patients who have undergone surgical wound debridement. Time saved in the operating room (OR) was evaluated. Method: A prospective evaluation of use of a topical haemostat in an OR setting was compared with retrospective data collected using electrocautery to understand the time-saving benefits of using a topical haemostat versus electrocautery. Results: A total of 52 patients were treated with the topical haemostat, and 89 patients with electrocautery. The topical haemostat was shown to be as effective in achieving haemostasis post-surgical debridement as electrocautery, with the added benefits of significant time savings in the OR (reducing the mean total OR time by 19.1%). Additionally, preprocedure and surgical procedure times in patients treated with the topical haemostat were significantly reduced. The results showed that wounds treated with the topical haemostat demonstrated a more advanced stage of healing, which may be a result of the lack of tissue damage demonstrated with the topical haemostat compared with electrocautery. Conclusion: This study found that the temporary topical haemostat was equally as effective as cauterisation in achieving haemostasis. In addition, significant saving in OR time was demonstrated relative to electrocautery. The improved OR times may translate into increased cost-effectiveness, relative to electrocautery, by increasing the number of surgical cases per day and/or using resources more effectively to treat more patients. It may also enable bleeding control in the outpatient clinic or at the bedside, freeing up costly OR time and enabling more effective management of healthcare resources.
Chronic neck sinus secondary to retained polyglactin 910 suture following sub-total thyroidectomy: a case study

Published: August 2020

Objective: Reaction to sutures is a rare cause of non-healing in clean wounds. Cases of severe reaction to silk sutures have been reported, causing chronic infection and failure of thyroidectomy wound healing. We report a case of retained polyglactin 910 suture presenting with a chronically discharging sinus of the neck after sub-total thyroidectomy. Case: The patient, a 37-year old female, presented with a simple benign multinodular goitre. She had subtotal thyroidectomy and was discharged on day six postoperatively, after satisfactory primary wound healing. The patient observed swelling, pus/discharge and extrusion of the suture in the neck three weeks after surgery. Discharge did not stop after initial wound debridement under local anaesthesia. Computed tomography (CT) scan showed a small area of ring-enhancement soft tissue density, anterior to the right thyroid remnant. Subsequent wound exploration under general anaesthesia revealed a sinus tract extending to the thyroid bed with undegraded strands of thickened polyglactin 910 suture. Suture remnants were removed and the wound healed satisfactorily a week later. Conclusion: Non-healing post thyroidectomy wounds should raise suspicion of a retained suture. Early recognition and surgical intervention will shorten the period of morbidity.
Chip scale GaAs optical phased arrays for high speed beam
steering
Authors: Wang Zihao , Liao Jiali , Sun Yanling , Han Xiang’e , Cao Yang , Zhao Run 
Published: August 2020

High speed photoelectronic optical phased arrays are demonstrated by
vertically arranged GaAs-AlGaAs slab waveguides. The optical phased
arrays are composed of 15-channel independently tuned waveguide with
end-fire emission. We achieve a very fast beam steering step response
of 0.34 µs, beam divergence of 4.7°, and beam steering ranges
of around 30°with side lobe level better than 8 dB. The presented
optical phased arrays provide a superior approach for high speed beam
steering on a nano-photoelectronic integrated chip.
Hybrid pulse propagation model and quasi-phase-matched four-wave mixing in multipass cells
Authors: Hanna Marc , Daher Nour , Guichard Florent , Délen Xavier , Georges Patrick 
Published: August 2020

We describe a nonlinear propagation model based on a generalized Schrödinger equation in the time domain coupled to Gaussian beam evolution through ABCD matrices that account for Kerr lensing in the spatial domain. This model is well suited to simulate propagation in mildly nonlinear systems such as multipass cells for temporal compression. It is validated against both a full

numerical model and recently reported experimental results in multipass cells, with excellent agreement. It also allows us to identify the physical mechanism for the recently reported parasitic appearance of spectral content in the 700–950 nm range in argon-filled multipass cells that are used to compress pulses at 1030 nm. We think this is due to a quasi-phase-matched degenerate four-wave mixing process. This process could be used in the future to perform wavelength conversion as is already done in fibers and capillaries.
Optical activity and excitation of surface plasmon polaritons with electromagnetically induced chiral media

Published: August 2020

Chiral materials possess some unusual properties for which they have attracted tremendous interest in recent research. In this paper, we discuss the interaction of electromagnetic fields with an initially isotropic material, making it anisotropic chiral by inducing magnetoelectric cross coupling. We consider a four-level double

Λ

-type configuration of an atomic ensemble, which is simultaneously sensitive to relative phase of the applied fields due to its closed-loop nature, providing an extra degree of freedom for controlling the birefringent nature of the medium. We show that the material splits a linearly polarized probe field into left- (LCP) and right-circularly polarized (RCP) components, and their angular divergence can be related to the optical activity of the medium. This leads to efficient modulation of the probe field, which may be helpful in accurate position detection of the transmitted beams and images. Next, we demonstrate that such a medium can be used to couple incident light with surface plasmons (SPs) in two ways: (1) as a prism-like coupler, in either Otto- or Kretschmann-type geometry, where excitation of SPs can be achieved beyond a certain incident angle of the interacting pulse in a plasmonic waveguide placed closed to it; and (2) direct excitation of SPs by a LCP or RCP beam from the chiral medium in a particular slit-type plasmonic waveguide. We find that the coupled modes in the latter case are unidirectional and highly tunable. Further, we show that the birefringent nature of the medium as well as the plasmonic field intensities can be efficiently manipulated with a number of controlling parameters. Our results may find applications in image coding, plasmonic sensors, and bio-photonics.

Functional variations of NFKB1 and NFKB1A in inflammatory disorders and their implication for therapeutic approaches
Authors: Kanigur-Sultuybek Gonul , Yenmis Guven , Soydas Tugba 
Published: August 2020

Abstract
Nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) is a sophisticated transcription factor that is particularly important in the inflammatory response, but it regulates more than 400 individual and dependent genes for parts of the apoptotic, angiogenic, and proliferative, differentiative, and cell adhesion pathways. NF-κB function is directly inhibited by the binding of inhibitor of κB (IκB), and the imbalance between NF-κB and IκB has been linked to the development and progression of cancer and a variety of inflammatory disorders. These observations might broaden the horizon of current knowledge, particularly on the pathogenesis of inflammatory diseases considering the roles of NF-κB and IκB. In this context, we focus this narrative review on a comparative discussion of our findings with other literature regarding variations of NFKB1 and NFKB1A and their association with susceptibility to widespread inflammatory disorders (such as atherosclerosis, morbid obesity, Behçet syndrome, Graves disease, Hashimoto disease) and common cancers (such as gliomas).
Prevalence and time course of elevated serum levels of liver enzymes in otherwise healthy Thai infants with breast milk jaundice: a cohort study
Authors: Kotcharit Pirarat , Chongsrisawat Voranush , Chatproedprai Susheera 
Published: August 2020

Abstract

Background
Neonatal jaundice and elevated levels of liver enzymes are found in infants with breast milk jaundice (BMJ).

Objectives
To determine the prevalence and duration of elevated serum levels of liver enzymes in Thai infants with BMJ.

Methods
We conducted a prospective study of Thai infants with BMJ, excluding those with pathological causes of jaundice. We measured the serum levels of total bilirubin (TB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and γ-glutamyl transferase (GGT); followed infants with elevated levels; and estimated the time for levels to become normal using Kaplan–Meier analysis.

Results
We included 42 infants (median age: 17.5 days) with BMJ, and elevated serum levels of at least 1 enzyme were found in 27 (64%) infants. We excluded 4 (10%) infants because they did not continue to be exclusively breastfed, 17 (40%) were lost to follow-up, and 21 (50%) completed the study. We found that 19 (45%) of the 42 infants had elevated GGT, 11 (26%) had elevated ALT, and 9 (21%) each had elevated AST and ALP levels. The median time for enzyme levels to normalize was 291 days (95% confidence interval [CI], 109.8 to 472.2) for ALT, 240 days (95% CI, 139.0 to 340.9) for AST, 184 days (95% CI, 4.4 to 363.6) for ALP, 120 days (95% CI, 74.6 to 164.5) for TB, and 63 days (95% CI, 61.44 to 64.6) for GGT. Infants were otherwise healthy during the follow-up.

Conclusion
The prevalence of elevated serum levels of liver enzymes in Thai infants was unexpectedly high, but the levels became normal spontaneously despite continued breastfeeding, which endorses a “watchful waiting” strategy in managing asymptomatic infants with BMJ.
Regularity for sub-elliptic systems with VMO-coefficients in the Heisenberg group: the sub-quadratic structure case
Authors: Wang Jialin , Zhu Maochun , Gao Shujin , Liao Dongni 
Published: August 2020

AbstractWe consider nonlinear sub-elliptic systems with VMO-coefficients for the case 1 <p< 2 under controllable growth conditions, as well as natural growth conditions, respectively, in the Heisenberg group. On the basis of a generalization of the technique of 𝓐-harmonic approximation introduced by Duzaar-Grotowski-Kronz, and an appropriate Sobolev-Poincaré type inequality established in the Heisenberg group, we prove partial Hölder continuity results for vector-valued solutions of discontinuous sub-elliptic problems. The primary model covered by our analysis is the non-degenerate sub-ellipticp-Laplacian system with VMO-coefficients, involving sub-quadratic growth terms.
