An investigation on the safety of children on the roads of Gaza, Palestine
No full textThe traffic safety system in Palestine needs major improvements. Traffic accident data in Gaza Strip are collected from crash reports recorded by the local Police. In many cases, roads are constructed without proper consideration of children’s needs. However, children and young kids use the roads as pedestrians, bicyclists, and occupants of vehicles. Moreover, they might choose to play on the road.This paper aims to investigate the situation of traffic safety of children in the Gaza Strip and to recommend measures to reduce their risk. This research is based on accident statistics recorded in the period between 2008 and 2018. Analysis was carried out to determine critical locations that have a high number of accidents, focusing on accidents that resulted in casualties and fatalities of children. Results show that the highest rate of children fatalities in the Gaza Strip was on Arterial Roads. According to the data collected in 2016, 2017, and 2018, the percentage of road traffic deaths of children are 60%, 68% and 59% respectively, which is higher than the average rate of child mortality in the world (52%) according to the world organization statistics. Gaza city has the largest number of children fatalities caused by road accidents in the Gaza Strip. This might be due to the high population density and heavy traffic. In order to reduce road accidents for children, it is necessary to control the speed of vehicles at school zones and to provide more safety measures for children on the roads, including illuminated pedestrian crossings for children. It is very important to provide children at schools and kindergartens with proper training on how to cross the street. It is also helpful to teach them some important traffic signs.</p
Treatment of diabetic muscular hyperplasia with natural and nutritional supplements
No full textSkeletal muscle is an important part of the human body. Most glucose metabolism is accomplished by skeletal muscle through insulin mediation. Skeletal muscle metabolism disorder can affect glucose metabolic homeostasis and insulin sensitivity of the body, and diabetic muscular Hypoplasia is a secondary lesion of muscle tissue caused by diabetes. In recent years, it has been found that in addition to mainstream western medicine and traditional Chinese and Western medicine combined treatment programs, natural products, and nutritional supplements also play an important role in the prevention and treatment of diabetic muscular Hypoplasia. Therefore, this paper will discuss the definition and pathogenesis of diabetic muscular Hypoplasia, as well as the prevention and treatment mechanism of some natural products and nutritional supplements, to provide more theoretical reference for non-drug targeted therapy of diabetic muscular Hypoplasia.</p
Seismic early warning systems for the transport cascade under the “SHIPKA” pass
No full textThe report presents an early warning system against earthquakes of the conceptual design of the tunnels under the “Shipka” Pass. Bulgaria gives many victims on the roads - those killed in traffic crashes and accidents. In the case of tunnel facilities in seismic areas, chain accidents in tunnel pipes are particularly dangerous. Early warning systems for tunnels make it possible to immediately stop traffic by the traffic police or automatically, to include additional ventilation equipment and turn on the additional reserve lighting installations.</p
Clinical mentorship for specialized care. Training paradigms and emerging challenges of assessment
No full textIntroduction: The following research is developed within the framework of the Project 135 of the National School of Nursery and Obstetrics (ENEO), with the contribution of the GIIIDEE Group (Interdisciplinary Group of Innovation and Research of Educational Assessment in Nursery). The global context had many significant changes starting 2019, since the emergence of COVID-19, a phenomenon that had significant repercussions on the training and assessment of the clinical skills in real scenarios with important implications for internships in students of higher education, both undergraduate and postgraduate.Theoretical framework: The theoretical referent is the Model of Reflexive Mentorship for Nursery. The clinical tutor is a professional specialist in nursery in charge of the clinical training of his/her students in real scenarios, in order to develop their critical thought, clinical judgment and decision making in the clinical field or community insert, both in metropolitan and foreign headquarters. Objective: The main goal of this document is to identify the training challenges and the assessment of the clinical mentorship for the tutors specialized in mentorships, orientations and guides in the clinical practices that take place in real contexts at different locations of the Unique Program of Nursery Specialties (PUEE).The methodology consisted on a bibliographical research in order to realize the state of art. The results show four important challenges for clinical mentorship at PUEE in the post-pandemic stage. The theoretical and methodological challenges are diverse in order to provide the mentorship as a unified policy with the commented perspectives that appear in the document. The teaching in situ and the formative assessment can potentiate the didactics in mentorship and the development of professional skills.</p
Androgen receptor, oxidative stress and inflammation at the crossroads of skin diseases

The development of effective treatments for skin diseases represents one of the biggest challenges in drug discovery. The pathogenesis of many skin disorders is complex and multifactorial. </p
Efficacy of a new Nutraceutical Formulation in preventing acute intestinal inflammation: New therapeutic opportunities for the treatment of diverticulitis?
No full textAcute diverticulitis is a painful, relatively sudden condition, characterized by the presence of low-grade inflammation in the colonic mucosa. Recent clinical trials supported the use of nutraceutical compounds in the treatment of patients with gastrointestinal disorders, including diverticulitis. To verify the hypothesis that nutraceutical ingredients my prevent diverticulitis development, we tested a combination of different natural active supplements, in a mouse model of acute intestinal inflammation. A nutraceutical formulation was administered daily in a prevention setting, by intrarectal enema. Inflammation severity was monitored using a Disease Activity Index (DAI) score, histological and endoscopic analysis, and quantification of Fecal Calprotectin (FC).Results showed that a combination of cranberry juice, pomegranate extract fruit in ellagic acid and inulin Fibruline®, prevented the development of experimental acute intestinal inflammation. This was confirmed endoscopically, in terms of reduced colon thickness and granularity of mucosal surface. Results were also confirmed histologically, not only by significant reduction of ulcerations, compared to control groups, but also by significant prevention of flogosis and inflammatory infiltration. Nutraceutical ingredients were also able to significantly reduce FC levels, confirming the anti-inflammatory properties of these dietary supplements.Our study supports the potential use of nutraceutical ingredients as a novel therapeutic approach to prevent acute diverticulitis.</p
Transcultural aspects in the treatment of posttraumatic and situational distress among middle eastern refugees
No full textThe increasing size of displaced populations seeking protection in third countries, should be considered in public health and especially in Psychotherapy in that countries. Refugees from the Middle East, usually from collective cultures, require special skills and modifications in the treatment setting. The cultural formulation (CF) of illness and suffering, as described in the recent version of medical standard manuals, is part of this challenge. Besides bridging cultures, the specific nature of trauma, especially highly complex issues such as a genocidal environment, - in our case example - the both transgenerational and the immediate persecution experienced by the Yazidi ethnic and religious minority - the therapist must also consider aspects of distress caused by displacement and exile. The article discusses the needed adaptations in the therapeutic setting, using the case of a Yezidi woman surviving ISIS violence abduction. Within the framework of our treatment, she received cognitive behavioral therapy with individual and group therapies (multimodal interventions) over a period of 10 weeks. Besides establishing stability, safety and orientation and strengthening her self-consciousness, her traumatic experiences were considered from an individual, collective, socio - cultural and political point of view. Both the causes and maintaining conditions of the symptoms as well as the symptoms themselves are being worked on. The sensitive confrontation with the trauma was particularly helpful for the patient. In addition, she learned to participate actively in everyday life and in new social contacts again during therapy. She was able to overcome the passive - avoidant lifestyle since the traumatic event in a somewhat stable manner, although she will still need time to develop a stable perspective in the long term. She was offered the prospect of renewed follow-up treatment if necessary.</p
Better neural images by combining ultrahigh field strength MRI with innovative MRI sequences
No full textBetter MRI scanning technologies and protocols can provide insights into neurological disorders. In this review, we describe the basic concepts of MRI and, in the process, we convey to the reader the relevance of MRI as a high-resolution imaging modality of tissue structure and metabolism. We outline the main parameters for improving MRI resolution and sensitivity for the ultimate goal of optimizing the diagnosis of neurological diseases. A key to obtaining high-resolution images by MRI is the strength of the magnet’s external field strength (Bo). The higher the field strength, the better the signal-to-noise (SNR) of acquired signals. Hence, this results in improved sensitivity and resolution of the reconstructed images. This article recapitulates the advancement of MRI technology towards Ultra-High-Field Strength (UHF) apparatus and the consequent benefits in SNR. Other keys towards improving MRI images include deftly modifying the parameters of longitudinal magnetization relaxation time (T1), transverse magnetization relaxation time (T2), repetition times between radiofrequency (RF) pulses (TR), and the time of reading post-pulse (TE). Such parameters can be controlled through acquisition software associated with the MRI machines. The review profiles the cumulative efforts by researchers to complement UHF-MRI hardware with innovative RF pulse sequences protocols such as Diffusion Weighted Imaging (DWI), Pulse Gradient Spin Echo (PGSE), Oscillating Gradient Spin Echo (OGSE), Blood Oxygen Level Dependent (BOLD)-MRI and Arterial Spin Label (ASL)-MRI. Collectively, these advances in both MRI hardware and software have pushed the field to attain a mesoscopic level of resolution. Further enhancements in analyzing MRI images through Artificial Intelligence (AI) algorithms may advance resolutions beyond the mesoscopic stage and perhaps even toward the microscopic resolution of living tissue.</p
Achieving humidification of inspired gases in the delivery room for very preterm infants: Rationale and set up
No full textNearly all very preterm infants will require some form of respiratory support in the neonatal unit. It is standard practice to humidify the inspired gases. It appears logical to bring this practice of humidification forward to the time immediately after birth. There is an evidence base for early provision of heated humidified gases in the delivery room, but because several forms of respiratory support may be needed (eg binasal prong CPAP and use of a T-piece resuscitator) this may be difficult to achieve. We describe a setup using a radiant warmer and humidification circuits to make this possible.</p
Voluntary Selection; Bringing Evolution at the Service of Humanity
No full textHuman populations can be characterized by their corresponding phenotypic profiles which do not necessarily align. These differences are not our points of strength in building harmonious societies and establishing a sustainable world order; it is therefore desirable to seek a pathway to resolve them. This article reflects on genetics as the most profound source of our differences and introduces Voluntary Selection as a means of acquiring genetic qualities and resolving the imbalance in their possession by different populations. Voluntary Selection is a healthcare program allowing for voluntarily involving the reproductive cells of another individual than the parents to conceive a child at the discretion of a parent population. Genetic qualities in this context are desired phenotypes as perceived by each population. The article then presents a computational approach through which thoughtful decisions about the design of a program can be made. These methods are applied to a pedigree data set of adult heights and the results are used to demonstrate the influence of the program design and the significance of its outcomes.</p
