Аdjustment disorders in students who have suffered psychoemotional stress: systematic review of diagnostics, treatment and preventive care

Currently, the mental health problem of students, which often leads to the creation of unfavorable foundations for the development of non-psychotic mental disorders, is particularly relevant and socially significant. The purpose of this article was to conduct a systematic literature review of the current state of the problems of students` adjustment disorders, taking into account interventions aimed at preventing and correcting them, and analyzing the results. We searched the electronic databases Oxford, Google Scholar, PubMed, Medline and Web of Science, ScienceDirect, Scopus, Cyberleninka, PsycInfo on prevalence, adverse effects, and interventions in students with adjustment disorders. Of the 25 studies published over the period from 2004 to 2020, 10 (40%) data on treatment and preventive measures are reported. The search revealed that interventions aimed at correcting and preventing adjustment disorders in students may improve various aspects of well-being, including psychological, pedagogical and medical ones. However, the evidence is limited by the relative inadequacy of long-term and reliable experimental studies. In view of this, it is advisable to further implement larger projects and conduct broader and longer-term research, which will contribute to a more reliable and in-depth study of the impact and effectiveness of such interventions. Based on a scientific search, the theoretical and methodological foundations of psychocorrection of students with adjustment disorders are substantiated, taking into account the specifics of the mental functioning of this category. While there are few works devoted to the study of developmental issues, clinical and psychopathological features, dynamics of non-psychotic mental disorders, taking into account gender and organizational factors in university students in the context of higher education reform, such issues require further study applying systemic approach in order to develop and implement in practice the early diagnosis as well as corrective and preventive measures.
Epidemiological Study of Return to Work and Mortality in Lung Cancer Survivors

Lung cancer is the second most common cancer and the leading cause of cancer-related deaths worldwide. Return to work (RTW) plays an important role for lung cancer survivors. Few studies focus solely on the relationship among possible variables and the RTW of lung cancer patients. The aim of our study was to examine sociodemographic, disease-related and work-related factors associated with RTW among lung cancer survivors in Taiwan. A total of 2206 employees who had been diagnosed with lung cancer at the Labor Insurance Database (LID), Taiwan Cancer Registry (TCR) and the National Health Insurance Research Database (NHIRD) during the period 2004–2015, were included in the study. We used the Cox proportional hazards model to investigate the associations between sociodemographic, disease-related and work-related factors on one hand and RTW on the other hand. The Kaplan–Meier method was used for analyzing the survival probability. Patients with an early cancer stage and those who underwent surgery had a higher likelihood of RTW. Factors including older age, male, higher monthly income and receipt of radiotherapy were inversely correlated with RTW. For lung cancer patients, RTW was a predictor of a lower risk of all-cause mortality in both the unadjusted and fully adjusted model. A better survival rate was found in stage III and IV lung cancer patients who had RTW. Sociodemographic and clinical-related variables had an impact on RTW among employees with lung cancer. RTW was correlated with a lower risk of all-cause mortality and better lung cancer survival. Our study showed the influence of RTW and independent confounding factors in lung cancer survivorship.
Where Does Gifted Education Go From Here: Chaos or Community?

For anyone who puts pen to paper, there can be no greater compliment than when someone reads your work, except when that person then takes the time to think about it and respond. As part of this special issue, almost 50 people took the time to engage on the topic of equity in gifted education and respond to the ideas I offered (see Peters, 2022). It was a gift that left me humbled. Because of the number of commentaries and range of ideas offered, my goal in this final paper was not to respond or react to them individually. Instead, I printed them all out, spread them across the floor of my office, and tried to find areas of agreement that might help the field move forward. As many gifted education scholars and practitioners have long lamented, the existence of disproportional representation within gifted and talented programs has gone on for too long and the time has come for bold, collective action. Although they covered a range of topics, in reading through the commentaries, there appeared to be two broad areas in which most of authors agree:
The Effect of Online Lecture on College Students’ Learning Achievement During the Covid-19 Pandemic

College student learning achievement shows a reflection of mastery of knowledge both in quality and quantity which is influenced by several factors. This study was conducted to determine the influence of lecturers' teaching factors, interactive media, and learning motivation on college student learning achievement during the Covid-19 pandemic. The approach used in the reseach is quantitative with 50 college students from three different universities as reseach subjects. Data were collected through a questionnaire instrument google form by method simple random sampling or randomly selected. Then analyzed using multiple logistic regression analysis technique with the help of SPSS for windows. This study shows the results that the teaching of lecturer has no effect on increasing college student learning achievement, but interactive media and learning motivation have a positive effect on college student learning achievement. This study recommends further research to examine the effect of lecturer competence on online lectures during the Covid-19 pandemic.
Enacting settler responsibilities towards decolonisation

This special issue showcases research exploring the work of settler individuals and groups in support of projects of decolonisation in Aotearoa New Zealand, Australia, Canada and Israel. The papers gathered here were developed from presentations at an international symposium held in Auckland, New Zealand and online in February 2021. As symposium organisers and editors of this collection, we speak and write as settler subjects ourselves, and this collection is situated within the field of Settler Colonial Studies (SCS). This editorial provides an opening framing of the field into which these papers speak, and a survey of some of the key themes within the wider literature. We aim firstly to locate this work within the wider field of scholarship and activism on decolonisation and decoloniality, delimiting the particular focus of decolonisation within settler-dominated contexts. We then discuss the critiques that have been mounted against SCS and some important defences of the field. We argue that while settler colonialism persists, work in SCS has a contribution to make – in highlighting and critiquing settler logics and in identifying changes that it is within the power of settler peoples themselves to make as a contribution towards Indigenous-led decolonisation. Further, we argue that decolonising settler societies must involve settlers learning to be ‘in relation’ with Indigenous worlds and people outside of deeply habituated logics and practices of domination. The papers gathered here provide examples of settler subjects at various points on the path of decolonising themselves and learning the work of ‘being in relation’.
Multi‐scale graph capsule with influence attention for information cascades prediction

Information cascade size prediction is one of the primary challenges for understanding the diffusion of information. Traditional feature‐based methods heavily rely on the quality of handcrafted features, requiring extensive domain knowledge and hard to generalize to new domains. Recently, inspired by the success of deep learning in computer vision and natural language processing, researchers have developed neural network‐based approaches for tackling this problem. However, existing deep learning‐based methods either focused on modeling the temporal characteristics of cascades but ignored the structural information or failed to take the order‐scale and position‐scale into consideration in modeling structures of information propagation. This paper proposed a novel graph neural network‐based model, called MUCas, to learn the latent representations of cascade graphs from a multi‐scale perspective, which can make full use of the direction‐scale, high‐order‐scale, position‐scale, and dynamic‐scale of cascades via a newly designed MUlti‐scale Graph Capsule Network (MUG‐Caps) and the influence‐attention mechanism. Extensive experiments conducted on two real‐world data sets demonstrate that our MUCas significantly outperforms the state‐of‐the‐art approaches.
Vibration and Sound Radiation of Sandwich Beams With Honeycomb Truss Core

Abstract The vibrations of and the sound radiation from sandwich beams with truss core are analyzed. The structure of the core is composed of a sequence of identical unit cells repeating along the beam length and across the core thickness. Each cell is composed of beam elements assembled to form a frame structure. Layouts with the typical honeycomb pattern arranged through the thickness of the core are here considered. This design represents an alternative with respect to the traditional application of honeycombs in sandwich construction. The proposed configuration provides sandwich beams with interesting structural as well as acoustic characteristics. A finite element model is developed to evaluate the structural and the acoustic behavior of the considered class of sandwich beams. The model is formulated by employing dynamic shape functions, derived directly from the distributed parameter model of beam elements. This formulation, often denoted as “spectral”, allows an accurate evaluation of the dynamic behavior of the considered structures at high frequencies and with a limited number of elements. In addition, the spectral model can be easily coupled with a Fourier transform based analysis of the sound radiated by the fluid-loaded structure. The model is used to analyze the performance of beams with various core configurations. The comparison is carried out in terms of structural response and sound transmission reduction index. In addition the sound pressure levels and distributions resulting from the beam vibration in an unbounded acoustic half-plane are evaluated and compared. Hexagonal and re-entrant configurations are considered in an effort to study the effects of core geometry on structural response and acoustic radiation.
A Brief Review on Hydrophobic Modifications of Glycol Chitosan into Amphiphilic Nanoparticles for Enhanced Drug Delivery

Glycol chitosan (GC) is the chitosan derivative that is capable of forming amphiphilic nanoparticles upon structure modifications at the reactive functional amine group on the polymer sugar backbone. Owing to the hydrophilic feature of GC and hydrophobic moieties that can be added to the GC structure, modifiable nanosystems were constructed to entrap poorly soluble drugs, mostly chemotherapeutic agents and several anti-inflammatory, anaesthetic, immunosuppressant, and antifungal drugs for more efficient delivery of the payload to the target site and improving the intended therapeutic effects. This review highlights the various hydrophobic molecules used in the chemical modification of GC to create amphiphilic nanoparticles for hydrophobic drug delivery, along with the summary of their physicochemical criteria and successful therapeutic enhancement achieved with the application of the drug-loaded amphiphiles. The biodegradable, GC-based nanoparticles particularly having the inner hydrophobic core and outer hydrophilic shell are an efficient system for drug entrapment, protection and targeting to improve the bioavailability and safety of the drug, in particular for cancer treatment purposes. The significant drug delivery enhancements achieved by these various hydrophobically-modified GC nanoparticles may provide the insights for their further use in nanomedicine.
Evaluation of Some Secondary Metabolites and Determination of the Antioxidant Potential of Different Extracts from the Plant of Pteridium aquilinum

The present study aims to make an evaluation of some secondary metabolites and determination of the antioxidant potential of P. aquilinum plant extracts obtained by means of a simple and rapid TLC method. The latter revealed the presence of terpenes, sterols, steroids, flavonoids, polyphenols, saponins, sugars and amino acids. The evaluation of the potential antioxidant was assessed on phenolic and flavonoid compounds. These compounds’ dosages revealed different levels, but the highest antioxidant activity was found in the hydro-ethanol extract followed by the aqueous extract. Among the two families of evaluated antioxidants, phenolic compounds were found to be higher in the hydroethanolic extract (75.18 mgEAG/gMS), followed by the aqueous extract (66.78 mgEAG/gMS) and lower in the ethanolic extract (12.39 mgEAG/gMS). Whereas flavonoids, less significantly elevated, showed values of 2.58 mgECa/gMS for the hydro-ethanolic extract, 2.24 mgECa/gMS for the aqueous extract and 1.58 mgECa/gMS for the ethanolic extract. However, the antiradical activity was also evaluated. Contrary to the antioxidant activity, the most important antiradical activity was observed on the hydroethanolic extract with a rate of 3.61 mg/mL, then a weak activity on the aqueous and ethanolic extracts respectively 6.18 mg/mL and 15.81 mg/mL, then less important on the aqueous How to cite this paper: Sompila, A.W.

Methicillin-resistant Staphylococcus aureus screening in healthcare workers: should a new protocol be introduced?

Background: In recent times, emerging resistance to majority of antibiotic classes seen in Methicillin-resistant Staphylococcus aureus (MRSA) isolates is of concern in hospital-acquired infection. MRSA carriage by healthcare workers (HCWs) has been documented to be as high as 50% in some studies. Higher carrier rate increases the risk of developing active infection as well as transmission of infection to the patients. The study aims to establish a relationship between MRSA carrier rate and healthcare workers of a tertiary care hospital in Pune and understand the need for screening regimens, based on the outcome.Methods: A cross-sectional study including health care workers from a tertiary care hospital working in different clinical departments was carried out. Data was collected by taking samples of nasal swabs of 115 HCWs and inoculated immediately on blood agar. Culture plates were incubated at 37°C for 24 hours and colonies were tested by routine diagnostic techniques. Antibiotic sensitivity was tested using cefoxitin discs on Mueller Hinton medium.Results: Prevalence of Staphylococcus aureus carriage was reported in 19 out of 115 (16.52%) healthcare workers, of which 63.2% were MRSA and 36.8% were MSSA. Prevalence of MRSA among Orthopaedic surgeons and General surgeons showed a carrier rate of 25% and 18.2% respectively. Nurses had a prevalence rate of 0.39 %. Overall prevalence of MRSA carriage in healthcare workers was reported to be 10.4%Conclusions: MRSA carriage among HCWs at the hospital is considerably high. The high prevalence of MRSA carriage emphasizes the need for stringent hospital infection control and regular screening regimen of HCWs.
Design of tunable modes and dual-band circular patch antenna using shorting posts

A simple analysis tool is presented, which can predict the resonant frequencies of all normal modes of a circular patch radiator when loaded with a number of passive conducting posts, distributed along the circumference of a circle concentric with the patch radiator. Two specific cases are investigated, where either the resonant frequencies can be tuned in a predictable manner or a closely spaced dual-band antenna with flexible band separation can be designed. It is also shown that for a perturbed circular patch TM/sub 01/ is the mode with lowest non-zero resonant frequency.
The moderating effect of parent-child relationship on children’s mental health during COVID-19 quarantine

Abstract The mandatory domestic quarantine from 23rd, January to 8th, April in Wuhan due to the coronavirus disease (COVID-19) is unprecedented in public health history in China. Its impact on people’s short-term negative psychological effects had been reported in both previous and current studies, especially for young children who are vulnerable to home environmental risks. Using data collected before and after Wuhan lockdown among children and parents in a Wuhan kindergarten T, this study provides empirical evidence on the negative impacts on parents and children from the pandemic, and particularly the moderating effect of parent-child relationship on children’s mental health. Qualitative analysis further illustrates that a good parent-child relationship could be fostered by parenting programs aiming at improving parenting skills, enhancing understanding of children’s psychological needs and promoting parent-child interactions. This indicates that parent-child relationship based on effective parenting programs are vital in reducing children’s emotional problems in the face of difficulties and disasters such as the COVID-19 quarantine.
Numerical investigation of the effect of geometry on the performance of a jet pump

Jet pump plays a major role in transporting materials. The efficiency of jet pump is poor and it usually has a sharp peak in the efficiency–discharge ratio curve. These are undesirable. In the past, experiments were conducted to understand the functioning of each component of the jet pump. The experimental method is reliable but performing parametric studies through experiments is problematic as it is difficult to systematically vary one parameter while keeping other parameters unchanged. In this study, numerical simulations were carried out to determine the effects of area ratio, setback distance, mixing tube length, and shape of the driving nozzle on the performance of the jet pump. It was seen that major losses arise in the jet pump primarily due to an improper mixing of primary and secondary fluids and because of the formation of recirculation near the mixing tube entrance. Based on these studies, a normalized mixing tube length (L m/D m) of 7–9, area ratio of 0.28, setback ratio of 1.54–2.02, and a modified shape of the outer wall of driving nozzle are recommended. Such geometry offers maximum efficiency of 40 per cent, a relatively flat efficiency curve, and a lower total pressure drop. This last effect is important from the energy requirement to drive the centrifugal pump.
The Association of Work Environments and Nurse-Nurse Collaboration: A Multicenter Cross-Sectional Study

Background: Along with the recent healthcare reform, intraprofessional collaboration in nursing is considered an essential factor for managing the challenges related to diverse roles and tasks of nurses in providing high quality care. There is lack of knowledge on how the nursing work environment could influence nurse-nurse collaboration. Purpose: The study aimed to assess the relationship between nursing work environment and nurses’ intraprofessional collaboration.Methods: A total of 300 nurses working in four teaching hospitals participated in this multicenter cross-sectional study. Data were collected using the Nurse-Nurse Collaboration Scale (NNCS) and the Practice Environment Scale of the Nursing Work Index (PES–NWI). The Pearson correlation test was used to analyze the data.Results: The results showed that the mean score of the PES–NWI was 2.65±0.32 out of 4. The highest and lowest scores belonged to the subscales of the nursing foundations for quality of care (2.86±0.31) and staffing and resource adequacy (2.24±0.49), respectively. The mean total score of nurse-nurse collaboration was 2.94±0.21 out of a score of 4. The results showed a significant positive relationship between nursing work environment and nurses’ intraprofessional collaboration (r=0.49, p<0.05). Conclusion: The nursing practice environment has a positive and significant relationship with nurse-nurse collaboration. Therefore, improving nurses’ practice environment and providing healthy workplaces could improve the intraprofessional nurse’s collaboration. Moreover, nurse managers should improve nurses’ skills in some areas of collaboration such as conflict management.
The SARS-CoV-2 B.1.1.529 Omicron virus causes attenuated infection and disease in mice and hamsters

Despite the development and deployment of antibody and vaccine countermeasures, rapidly-spreading SARS-CoV-2 variants with mutations at key antigenic sites in the spike protein jeopardize their efficacy. The recent emergence of B.1. 1.529, the Omicron variant1,2, which has more than 30 mutations in the spike protein, has raised concerns for escape from protection by vaccines and therapeutic antibodies. A key test for potential countermeasures against B.1. 1.529 is their activity in pre-clinical rodent models of respiratory tract disease. Here, using the collaborative network of the SARS-CoV-2 Assessment of Viral Evolution (SAVE) program of the National Institute of Allergy and Infectious Diseases (NIAID), we evaluated the ability of multiple B.1. 1.529 Omicron isolates to cause infection and disease in immunocompetent and human ACE2 (hACE2) expressing mice and hamsters. Despite modeling and binding data suggesting that B.1. 1.529 spike can bind more avidly to murine ACE2, we observed attenuation of infection in 129, C57BL/6, and BALB/c mice as compared with previous SARS-CoV-2 variants, with limited weight loss and lower viral burden in the upper and lower respiratory tracts. Although K18-hACE2 transgenic mice sustained infection in the lungs, these animals did not lose weight. In wild-type and hACE2 transgenic hamsters, lung infection, clinical disease, and pathology with B.1. 1.529 also were milder compared to historical isolates or other SARS-CoV-2 variants of concern. Overall, experiments from multiple independent laboratories of the SAVE/NIAID network with several different B.1. 1.529 isolates demonstrate attenuated lung disease in rodents, which parallels preliminary human clinical data.
