Reward-related predictors of symptom change in behavioral activation therapy for anhedonic adolescents: A multimodal approach
Authors: Webb Christian A. , Murray Laura , Tierney Anna O'Brien , Forbes Erika E. , Pizzagalli Diego A.
Published: June 2022

Background: Anhedonia is a cardinal characteristic of depression which predicts worse treatment outcome and is among the most common residual symptoms following treatment. Behavioral Activation (BA) has been shown to be an effective treatment for depressed adults, and more recently, depressed adolescents. Given its emphasis on systematically and gradually increasing exposure to and engagement with rewarding activities and experiences, BA may be a particularly effective intervention for adolescents experiencing anhedonia and associated reward system dysfunction.Method: Anhedonic adolescents (AA; n = 39) received 12 weekly sessions of BA and completed a multimodal (i.e., neural, behavioral, and self-report [ecological momentary assessment]) assessment of reward function at pre-treatment and post-treatment (as well as weekly self-report assessments of anhedonia). Typically developing adolescents (TDA; n = 41) completed the same measures at corresponding timepoints. Multilevel models tested pre-treatment reward-related predictors of anhedonia improvement, as well as change in reward measures over the course of BA. Results: Analyses revealed significant reductions in anhedonia following BA treatment. Enhanced pre-treatment neural (striatal) reward responsiveness predicted greater anhedonia improvement. In contrast, baseline self-report and behavioral reward measures did not predict treatment outcome. A group x time interaction revealed greater increases in both reward- and loss-related neural responsiveness among AA relative to TDA adolescents.Conclusions: Consistent with a capitalization (rather than compensatory) model, pre-treatment neural ¬– but not self-report or behavioral – measures of enhanced reward responsiveness predicted better BA outcome. In addition to alleviating anhedonia, successful BA may also increase neural sensitivity to affectively salient (e.g., reward- and loss-related) stimuli among anhedonic youth.

Published: June 2022

Local governments are increasingly utilizing social media to trigger citizens’ engagement. So far research has provided evidence regarding the way local governments use social media and the impact of various post elements on users’ engagement by focusing mainly on two platforms, Facebook and Twitter. Less is known about the communication practices of local governments on Instagram and their effects on users’ engagement. Perea et al. (2021) examined Instagram use by Andalusian local governments and found that this platform can be used as an alternative channel for low-cost advertising as well as an effective platform for the visual promotion of a city. In another study, Faber (2021) found that municipalities post messages regarding culture and leisure activities, taking advantage of the aesthetic nature of the platform. In addition, Gruzd et al. (2018) highlighted the” clicktivist” nature of Instagram that generates significantly more likes from citizens compared to other social media such as Twitter implying an advantage of Instagram for generating users’ reactions. It should also be noted that there is scarce evidence concerning the factor that influences users’ engagement with Instagram practices of local governments. A few related studies have shown that the different types of content generate differential degrees of users’ reactions (likes, comments). For example, cultural and promotional posts can increase the number of likes whereas posts about public works generate more comments. Understanding how the various types of content impact users’ engagement on Instagram are important for identifying the communication strategies that will be more effective in triggering users’ reactions. Thus, the present study will try to enrich the limited literature on the effective use of Instagram by local governments. Thus, the aim of this study is twofold. First, to identify the communication practices of Greek local governments on Instagram in terms of content type, dialogic communication, and post characteristics (e.g., usage of links, hashtags, emojis), and second to examine their impact on users’ engagement (i.e., likes, comments).

A Novel Gut-Orchestrated Exercise Theory on Obesity and Cancer Prevention
Authors: Nikkhah Akbar
Published: June 2022

A novel gastrointestinal tract (gut) mediated exercise theory was developed to explain how highly disciplined physical activity can help prevent obesity and cancer. The gut serves the modern human body as another brain. The gut microbiota plays crucial regulatory roles in determining the health of the gut itself and entire body. Adequate exercise has been recommended to increase energy expenditure and reduce fat deposition, especially visceral adiposity. This article presents a gut-brain axis related theory based upon which with adequately intense and regular physical activity, the gut does assimilate foods and nutrients more effectively. Thus, the amount and flow of excreta are optimized. As such, the excretion of unhealthy compounds such as cholesterol, fatty acids, and to some extent starch increase. As a result, hepatic load of nutrients decrease. Consequently, the entire body tissues experience a relief in the time-consuming and energy-burning process of metabolite turnover and detoxification. Therefore, regular intense exercise does not only reduce unhealthy nutrient deposition, it can also decrease appetite and nutrient intake. This theory should permit innovative research to formulate new gut-centered public recommendations regarding the importance of adequate regular exercise to help prevent obesity and cancer and associated metabolic complexities.

Published: June 2022

Surgical thrombectomy is considered the gold standard approach for removal of thrombotic disease within the right heart (RiTH), however some patients have prohibitive surgical risk and the percutaneous approach has been increasingly popular in the past few years. In this manuscript, we present two case reports of patients with both acute and chronic right atrial thrombi; in whom elevated surgical risk deemed them not surgical candidates and both successfully underwent mechanical thrombectomy with Flow Triever suction catheter and En snare endovascular system. To our knowledge, these are the first reported cases of the use of both of these devices for treatment of RiTH.

Sheppard Siegal Syndrome (Familial Mediterranean fever): The Value of Serum Amyloid a in the Diagnosis and Treatment Decision
Authors: Jalal Al-Mosawi Aamir
Published: June 2022

Background: Sheppard Siegal syndrome was first described in 1945 by Sheppard Siegal. He described in details an extraordinary syndrome that was often undiagnosed because it was not clearly understood. The syndrome described by Siegal is characterized by recurrent attacks of fever, and commonly begins during childhood, and may begin as early as seven months. Attacks of the syndrome usually last two to three days and, often recur every few weeks. Siegal emphasized that progressive renal disease in the form of amyloidosis or chronic glomerulonephritis is the most serious organ involvement. Four mutations in the MEFV gene have been reported to account for 86% of the mutations causing Sheppard Siegal syndrome. Colchicine has been used for the treatment and prevention amyloidosis. Patients and methods: The father of a 3.5-year Iraqi boy (Born on the 19th of March, 2018) of Kurdish origin living in Dubai consulted us during September, 2021 about the appropriate treatment of his son who was experiencing recurrent attacks of high fever over about one year. He consulted us after consulting few physicians in Dubai who were prescribing oral and injectable acetaminophen for the symptomatic control of fever during the attacks. The case was studied and an evidenced-based recommendation is presented in this paper. Results: The attacks of fever were persisting for few days and were not generally associated with mo other significant symptoms other than the general ill health and tiredness that can be associate with fevers of various etiologies. Between the attacks, the boy was in good health and had normal activity. The father was unaware of a similar illness in their relatives. Serum amyloid A (EIA) was performed during the last attack of fever during August, 2021, and was very high (517mg/L), as the normal level is less than 6.40517mg/L. Analysis of regions of the MEFV gene showed no pathogenic variants were detected. Conclusion: We have recommended monitoring serum amyloid A during attack free periods, and initiate colchicine therapy if serum amyloid A was found high to prevent the development of amyloidosis according to the evidence provided by Berkun et al (2007).

Authors: MB Sule
Published: June 2022

Tension pneumocephalus is an unusual bad life-threatening neurosurgical emergency, this is the equivalent of tension pneumothorax. This often follows head trauma, epidural injections, complicating neurological spinal, craniofacial or sinus surgery. This is a forty-five-year-old man that was involved in a road traffic accident, was referred for a computed tomography of the brain on account of altered consciousness, irrational behavior, and restlessness. A non-contrast enhanced computed tomography of the brain was done, this demonstrated multiple areas of cortical discontinuity in the facial and skull vaults in keeping with fractures, extensive negative density (HU: -968) hypodensity in the frontal region bilaterally causing marked inferior displacement of both frontal lobes of the brain, with associated splaying of the interhemispheric fissure likened to the ‘Mount Fuji sign’ of severe/tension pneumocephalus. Pockets of negative density hypodensities are also noted in both cerebral hemispheres in keeping with pneumatoceles are also demonstrated. Generalized effacement of sulci and gyri in keeping with cerebral edema is also demonstrated. The outcome of the patient in the peripheral center was not known as at the time of this report, because all effort to get across to the patient and relations proved abortive. We present a case of tension pneumocephalus following road transport accident, to review the computed tomographic features due to its peculiar presentation.

TIME SYNCHRONIZATION MECHANISMS FOR SPACEFIBRE NETWORKS
Authors:   St. Petersburg State University of Aerospace Instrumentation, Suvorova Е. А.
Published: June 2022

Real-time requirements are very important for most aerospace systems. To support real-time mechanisms, time synchronization is required throughout the network, in all network devices. SpaceFibre is developed for aerospace networks. However, the current version of this standard does not include any time synchronization mechanism. In this article, we look at the time synchronization mechanisms supported by the standards currently used for aerospace systems, and suggest several mechanisms for time synchronization in SpaceFibre networks. We present estimates of the achievable synchronization accuracy for the proposed mechanisms. The paper proposes the implementation of these mechanisms based on a dynamically reconfigurable unit of the local time controller. This implementation made it possible to evaluate the achievable characteristics of all proposed mechanisms. It is planned to use it in further research, since it provides the ability to reconfigure to implement other modes. In this paper, we show that in different networks it may be appropriate to use different synchronization mechanisms depending on the user’s requirements. Our implementation with dynamic reconfiguration provides the ability to use various mechanisms, including when implemented using ASIC technology.

Saint Theodore Stratelates and the Rus’-Byzantine wars
Authors: Fylypchuk Oleksandr
Published: June 2022

The article discusses the function of memory of saint Theodore Stratelates as a protector on the battlefield in the Rus’-Byzantine wars. A thorough analysis of the evidence found in the Life of Saint Basil the Younger, History of Leo the Diacon, Synopsis of John Skylitzes and the Rus’ian Primary Chronicle leads us to conclude that Theodore Stratelates’ memory was created after the attack of Rus’ on the Constantinople in 941 and the campaign of John Tzimisces against the Rus’ in 971. The comparison of sources (the Life of Saint Basil the Younger and the Rus’ian Primary Chronicle) carried out by the author enables to think that the strategos Theodore in the narrative of the Life of Saint Basil the Younger was a saint. The study of both cases shows that the war of emperor John Tzimisces with the Rus’ of Svjatoslav the Glorious changed the geography of the cult of Theodore Stratelates. The attention is paid to the sources of two Byzantine narratives (the History of Leo the Diacon and a Synopsis of John Skylitzes) about the role of Theodore Stratelates in the battlefield at Dorostolon. As such the renaming of Dorostolon to Theodoropol became part of the military ideology of emperor John Tzimisces, being its apology of the cult of Theodore Stratelates in this land. This gives some grounds for assuming that this change of the geography of the cult in Dorostolon greatly influenced later chroniclers such as author of the Rus’ian Primary Chronicle.

The article presents the results of the study held in the Chelyabinbsk State Institute of Culture in 2021. The study aimed at the evaluation by employers’ organizations of the university graduates’ preparation level, requirements of professional sphere to the competencies of culture workers, and determination of forms and directions of employers’ participation in educational process. The study showed comparatively high evaluation of educational system results (training of a graduate), the developed personal characteristics, universal and professional competencies of a culture worker. The authors have also revealed a dominant orientation at short-term, local (according to scales, intensity and the tasks realized) directions and forms of interaction between the university and regional sphere of culture. The choice of tools for such interactions indicates a lack of long-term aims, strategic character and focus on the solution of the personnel potential reproduction tasks and integration of cultural institutions into educational process, organization of joint scientific-research, artistic and creative, sociocultural projects. Meanwhile, interaction potential of cultural activity and professional education spheres becomes a factor of protecting and development of regional system of culture, sociocultural transformation of the corresponding territories.
Potential Involvement of Varicella Zoster Virus in Alzheimer’s Disease via Reactivation of Quiescent Herpes Simplex Virus Type 1
Authors: Cairns Dana M. , Itzhaki Ruth F. , Kaplan David L.
Published: June 2022

Background: Varicella zoster virus (VZV) has been implicated in Alzheimer’s disease (AD), and vaccination against shingles, caused by VZV, has been found to decrease the risk of AD/dementia. VZV might reside latently in brain, and on reactivation might cause direct damage leading to AD, as proposed for herpes simplex virus type 1 (HSV-1), a virus strongly implicated in AD. Alternatively, shingles could induce neuroinflammation and thence, reactivation of HSV-1 in brain. Objective: To investigate these possibilities by comparing the effects of VZV and HSV-1 infection of cultured cells, and the action of VZV infection on cells quiescently infected with HSV-1. Methods: We infected human-induced neural stem cell (hiNSC) cultures with HSV-1 and/or VZV and sought the presence of AD-related phenotypes such as amyloid-β (Aβ) and P-tau accumulation, gliosis, and neuroinflammation. Results: Cells infected with VZV did not show the main AD characteristics, Aβ and P-tau accumulation, which HSV-1 does cause, but did show gliosis and increased levels of pro-inflammatory cytokines, suggesting that VZV’s action relating to AD/dementia is indirect. Strikingly, we found that VZV infection of cells quiescently infected with HSV-1 causes reactivation of HSV-1 and consequent AD-like changes, including Aβ and P-tau accumulation. Conclusion: Our results are consistent with the suggestion that shingles causes reactivation of HSV1 in brain and with the protective effects against AD of various vaccines, as well as the decrease in herpes labialis reported after certain types of vaccination. They support an indirect role for VZV in AD/dementia via reactivation of HSV-1 in brain.

Background: Global amyloid-β (Aβ) deposition in the brain can be quantified by Aβ-PET scans to support or refute a diagnosis of preclinical Alzheimer’s disease (pAD). Yet, Aβ-PET scans enable quantitative evaluation of regional Aβ elevations in pAD, potentially allowing even earlier detection of pAD, long before global positivity is achieved. It remains unclear as to whether such regional changes are clinically meaningful. Objective: Test the hypothesis that early focal regional amyloid deposition in the brain is associated with cognitive performance in specific cognitive domain scores in pAD. Methods: Global and regional standardized uptake value ratios (SUVr) from 18F-florbetapir PET/CT scanning were determined using the Siemens Syngo.via® Neurology software package across a sample of 99 clinically normal participants with Montreal Cognitive Assessment (MoCA) scores≥23. Relationships between regional SUVr and cognitive test scores were analyzed using linear regression models adjusted for age, sex, and education. Participants were divided into two groups based on SUVr in the posterior cingulate and precuneus gyri (SUVR≥1.17). Between group differences in cognitive test scores were analyzed using ANCOVA models. Results: Executive function performance was associated with increased regional SUVr in the precuneus and posterior cingulate regions only (p < 0.05). There were no significant associations between memory and Aβ-PET SUVr in any regions of the brain. Conclusion: These data demonstrate that increased Aβ deposition in the precuneus and posterior cingulate (the earliest brain regions affected with Aβ pathology) is associated with changes in executive function that may precede memory decline in pAD.

Background: Considering the world’s rapidly increasing life expectancy, with people working and maintaining active lifestyles longer than ever before, addressing the effects of aging on cognition is of utmost importance. A greater understanding of cognitive aging may also be critical in distinguishing natural cognitive aging from pre-clinical stages of Alzheimer’s disease and related cognitive disorders. Objective: To systematically examine the association between aging and cognitive performance in a cognitively and otherwise healthy probability population-based sample using a computer-based method. Methods: This cross-sectional study enrolled 673 cognitively and otherwise healthy participants aged 25–89 years (mean age 52.3±14.2 years, 52.5% of whom were female) from the Kardiovize study cohort. Mild cognitive impairment and dementia cases were excluded, followed by measurement of cognitive performance with the computer-administered Cogstate Brief Battery. We used ANCOVA and Modified Signed-Likelihood Ratio tests to examine patterns of cognition across age groups. Results: We found a gradual decrease in cognitive performance across the lifespan, which required two decades to demonstrate significant changes. In contrast to attention and learning, psychomotor speed and working memory showed the most significant age-related decrease and variability in performance. The established pattern of cognitive aging was not altered by sex or education. Conclusion: These findings corroborate, validate, and extend the current understanding of natural cognitive aging and pinpoint specific cognitive domains with the most extensive age-related interindividual differences. This will contribute to the development of strategies to preserve cognition with aging and may also serve to improve early diagnostics of cognitive disorders using computer-based methods.
Artificial immune algorithm-sparrow search algorithm and its application in network intrusion detection
Authors: Liu Jianhua , Wang Zhiheng
Published: June 2022

In order to solve the problem that the population diversity of sparrow search algorithm (SSA) decreases and easily falls into the local optimal solution when it approaches the global optimal, an artificial immune algorithm-sparrow search algorithm (AIA-SSA) is proposed in this paper by combining artificial immune algorithm and sparrow search algorithm. This paper uses 10 benchmark functions for experimental simulation of AIA-SSA algorithm, and compares it with five widely used intelligent algorithms and SSA. Experimental results show that AIA-SSA overcomes the deficiency of SSA and improves the search accuracy, convergence speed and stability of the algorithm. Meanwhile, this paper applies AIA-SSA to network intrusion detection and constructs a network intrusion detection model based on support vector machine (SVM). After testing, the accuracy of AIA-SSA-SVM prediction for various network attacks has been greatly improved. It not only shows that AIA-SSA-SVM has a broad application prospect in the field of network security, but also verifies the feasibility and advanced nature of AIA-SSA in solving practical engineering problems.

Published: June 2022

With the development of Internet+medicine, online medical treatment has gradually become the new development direction of medical industry. Many hospitals provide online registration services to the public, and due to the lack of professional medical knowledge of patients, the problem of wrong registration often occurs. How to use deep learning technology to provide professional help to patients and reduce the waste of medical resources has become an urgent problem. To address the above problems, this paper proposes an ERNIE-based text classification model for intelligent triage. The model consists of two parts, ERNIE and BiGRU. The pre-training model ERNIE is used to extract the feature representation of the text, and then input to the BiGRU neural network to get the text classification results. Compared with different models on 2 datasets, the experimental results show that the model proposed in this paper has better accuracy and recall than other models.

Published: June 2022

BACKGROUND: There are anecdotal reports of high job turnover of Individual Placement and Support employment specialists. However, no studies have addressed this issue. OBJECTIVE: To explore whether turnover rates among employment specialists are higher compared to public sector employees along with the correlates of turnover intentions. METHODS: A repeated cross-sectional study collected data from 40 employment specialists in Norway using validated scales to measure job perceptions. Turnover intentions were the main outcome. RESULTS: Turnover rate of employment specialists (45.0%) was significantly higher than the average turnover rate of other occupations in the public sector (27.1%) in the same geographical regions (x2 = 6.5, df = 1, p = 0.01). After adjusting for potential confounders, five factors remained significantly associated with turnover intentions in directions as expected: general job satisfaction (β= –0.33, p < 0.05), satisfaction with current work (β= –0.35, p < 0.05), satisfaction with supervision (β= –0.28, p < 0.05), work meaningfulness (β= –0.42, p < 0.05) and Negative emotionality personality trait (β= 0.58, p < 0.05). CONCLUSIONS: Addressing turnover will positively impact on productivity and job satisfaction of employment specialists along with continuity of employment support for people with mental health conditions.

Published: June 2022

BACKGROUND: The similar elastic modulus of resin-matrix ceramics to dentin has resulted in their recent widespread application clinically. Nevertheless, the bacterial environment of oral cavity can degrade the resin composite. OBJECTIVE: The objective was to analyse the effect of S. mutans and its fluoride-resistant strains on the adhesion of three CAD/CAM ceramics. METHODS: S. mutans UA159 (UA) was identified, and its fluoride-resistant strain (FR) was induced. For crack observation, three kinds of CAD/CAM ceramics (IPS Empress, Lava Ultimate and Vita Enamic) were bonded with tooth complex (enamel, dentin and flowable resin) through adhesive. For micro-tensile test, ceramics were bonded with flowable resin, and cut into strip test pieces. Then specimens were immersed into the UA, FR and the control solution (BHI) separately for 14 d. Ceramic-adhesive interface and adhesive-tooth complex interface were observed and analyzed through electron microscope and stereomicroscope. Micro-tensile test was conducted. RESULTS: Specimens in bacterial solutions had more cracks and comparatively weaker micro-tensile strength than those in BHI. In ceramic-adhesive interface, Lava Ultimate produced the most cracks. In adhesive-tooth complex interface, adhesive-dentin produced the most cracks. Meanwhile, IPS Empress had the strongest micro-tensile strength when bonded with resin. CONCLUSIONS: S. mutans and its fluoride resistant strain can cause cracks in the bonding of ceramics and dental tissue, especially resin-matrix ceramic and dentin, and weaken the bonding strength between ceramics and resin.
