Gamified Web-Delivered Attentional Bias Modification Training for Adults With Chronic Pain: Protocol for a Randomized, Double-blind, Placebo-Controlled Trial
Authors: Vermeir Julie F , White Melanie J , Johnson Daniel , Crombez Geert , Van Ryckeghem Dimitri M L
Published: November 2021

Background

To date, research has found variable success in using attentional bias modification training (ABMT) procedures in pain samples. Several factors could contribute to these mixed findings, including boredom and low motivation. Indeed, training paradigms are repetitive, which can lead to disengagement and high dropout rates. A potential approach to overcoming some of these barriers is to attempt to increase motivation and engagement through gamification (ie, the use of game elements) of this procedure. To date, research has yet to explore the gamified format of ABMT for chronic pain and its potential for the transfer of benefits.

Objective

The aim of this study is to investigate the effects of a gamified web-delivered ABMT intervention in a sample of adults with chronic pain via a randomized, double-blind, placebo-controlled trial.

Methods

A total of 120 adults with chronic musculoskeletal pain, recruited from clinical (hospital outpatient waiting list) and nonclinical (wider community) settings, will be included in this randomized, double-blind, placebo-controlled, 3-arm trial. Participants will be randomly assigned to complete 6 web-based sessions of dot-probe nongamified sham control ABMT, nongamified standard ABMT, or gamified ABMT across a period of 3 weeks. Active ABMT conditions will aim to train attention away from pain-relevant words. Participant outcomes will be assessed at pretraining, during training, immediately after training, and at the 1-month follow-up. Primary outcomes include pain intensity, pain interference, and behavioral and self-reported engagement. Secondary outcomes include attentional bias for pain, anxiety, depression, interpretation bias for pain, and perceived improvement.

Results

The ethical aspects of this research project have been approved by the human research ethics committees of the Royal Brisbane and Women’s Hospital (HREC/2020/QRBW/61743) and Queensland University of Technology (2000000395). Study recruitment commenced in August 2021 and is ongoing. Data collection and analysis are expected to be concluded by October 2022 and January 2023, respectively.

Conclusions

This trial will be the first to evaluate the effects of gamification techniques in a pain ABMT intervention. The findings will provide important information on the potential therapeutic benefits of gamified pain ABMT programs, shed light on the motivational influences of certain game elements in the context of pain, and advance our understanding of chronic pain.

A Novel Peer-to-Peer Coaching Program to Support Digital Mental Health: Design and Implementation
Authors: Rosenberg Benjamin M , Kodish Tamar , Cohen Zachary D , Gong-Guy Elizabeth , Craske Michelle G
Published: November 2021

Many individuals in need of mental health services do not currently receive care. Scalable programs are needed to reduce the burden of mental illness among those without access to existing providers. Digital interventions present an avenue for increasing the reach of mental health services. These interventions often rely on paraprofessionals, or coaches, to support the treatment. Although existing programs hold immense promise, providers must ensure that treatments are delivered with high fidelity and adherence to the treatment model. In this paper, we first highlight the tension between the scalability and fidelity of mental health services. We then describe the design and implementation of a peer-to-peer coach training program to support a digital mental health intervention for undergraduate students within a university setting. We specifically note strategies for emphasizing fidelity within our scalable framework, including principles of learning theory and competency-based supervision. Finally, we discuss future applications of this work, including the potential adaptability of our model for use within other contexts.
Turning Adversity into Capitals among Low Income First Generation Students of Color: Exploring Interdependence of Multiple Capitals
Authors: Jackson Marcelle , Choi Jung-ah
Published: November 2021

Much literature have documented that low income, first generation college students tend to contend with challenges and hardships such as financial constraints, low parental support, lack of college information, and lack of social networks. However, a growing number of the studies reverse such “deficit” view on first generation students of color, and assert that resources of traditionally disadvantaged students become a community cultural wealth for accessing privilege. This study collects the experiences of low income students of color who graduated from PWIs in the U.S. higher education system. In so doing, the study uses Yosso’s Community Cultural Wealth as a theoretical framework, and analyzes the experiences in terms of how they transform their resources into capitals. The analysis of the data shows that each participant leverages Yosso’s six capitals in the way to gain successful educational attainment. Unfulfilled parental dream and pitying parents turn to valuable family and aspirational capitals; lack of clear goals and lack of guidance compelled the participants to be able to navigate through possible social networks. The data also shows how one capital reinforces and intersects with other capitals.

KONTAKTI DECE SA RODITELJIMA LIŠENIM SLOBODE – IZAZOVI TOKOM PANDEMIJE KOVID 19
Authors: Pucarevic Bojana , Skrobic Ljiljana
Published: November 2021

Odsluženje zatvorske kazne predstavlja izazovan period, kako za onog ko služi kaznu, tako i za članove njegove porodice, a naročito decu. Brojna istraživanja pokazuju da su ova deca izložena višestrukim rizicima, a jedan od rizika jeste prekid kontakata, a samim tim i odnosa deteta sa roditeljem koji je na odsluženju zatvorske kazne. Neki od razloga za to mogu biti finansijske ili organizacione prirode, nerazrešen odnos ili ljutnja deteta prema roditelju. Takođe, politike posete zatvorima nisu prilagođene ovoj vrsti kontakta i ne odražavaju potrebe dece. Potrebe ove dece često ostaju nevidljive i neprepoznate i van nadležnosti krivično-pravnog sistema.
Napred navedeni izazovi su postali kompleksniji tokom pandemije KOVID 19, koja je aktuelna više od godinu dana. U Srbiji je ovaj period obeležilo, između ostalog, i uvođenje vanrednog stanja. Kao reakcija na zdravstvene rizike, zatvori su preduzeli mere koje su podrazumevale obustavljanje poseta, a potom realizovanje poseta uz strogo pridržavanje epidemioloških mera koje podrazumevaju i fizičku distancu. Sve ovo se reflektovalo na kontakte dece sa roditeljima lišenim slobode.
Predmet rada biće predstavljanje rezultata istraživanja koje se bavilo načinom održavanja kontakata i prevazilaženjem izazova u održavanju ovih kontakata tokom pandemije KOVID 19 u ustanovama za izvršenje krivičnih sankcija u Srbiji. Rad ima za cilj da ukaže na značaj očuvanja porodičnih veza, a sa naglaskom na potrebe i prava dece i u periodu krize.

Improved Energy and Communication for Underwater Wireless Sensor Network Based Location Estimation
Authors: Jain Priyanka
Published: November 2021

Abstract: The area of underwater wireless sensor networks (UWSNs) is garnering an increasing attention from researchers due to its broad potential for exploring and harnessing oceanic sources of interest. Because of the need for real-time remote data monitoring, underwater acoustic sensor networks (UASNs) have become a popular choice. The restricted availability and nonrechargeability of energy resources, as well as the relative inaccessibility of deployed sensor nodes for energy replenishment, forced the development of many energy optimization approaches un the UASN. Clustering is an example of a technology that improves system scalability while also lowering energy consumption. Due to the unstable underwater environment, coverage and connectivity are two important features that determine the proper detection and communication of events of interest in UWSN. A sensor network consists of several nodes that are low in cost and have a battery with low capacity. In wireless sensor networks, knowing the position of a specific device in the network is a critical challenge. Many wireless systems require location information from mobile nodes.

Mathematical Modelling and Experimental Investigation of Abrasive Jet Machining for Various Abrasive Particles
Authors: Varia Manthan N.
Published: November 2021

Abstract: Abrasive water-jet machining operates by the impingements of a high velocity abrasive laden water-jet against the work piece. The jet is formed by mixing abrasive particles with high-velocity water in the mixing region and is forced through the orifice. The accelerated jet exiting the nozzle travels at a very high velocity and cuts as it passes through the work piece. It is a difficult task of predicting the values of major cutting performance measures in Abrasive Water Jet (AWJ) cutting. AWJ cutting process involves a large number of process and material parameters, which are related to the water-jet, the abrasive particles, and work-piece material. Those parameters are expected to affect the material removal rates and depth of penetration. In this paper, various models of wear by particle erosion and the most accepted models for predicting the depth of penetration in AWJ cutting are reviewed. However, there has been very little reported study on AWJ machining using various abrasive particles. In this paper, an attempt has been made for the development of the predictive mathematical model for AWJ cutting with various abrasive particles having different geometrical shapes and physical properties. Also, their effect on the target material has also been studied. Afterward, this model is verified with the experimental investigation.

Published: November 2021

The study on the effect of polymer concentration on in vitro drug release profile revealed that there is a change in vitro drug release parameters (t50, t80, and MDT) with a change in polymer concentration. Fraction of HPMC K4M, HPMC K 100 M, and Ethyl Cellulose were required to be 15, 10, and 7 mg respectively for designing optimized batch F7. The release rate of Colchicine decreased proportionally with an increase in the concentration of ethyl Cellulose and HPMC K100 M. Also the high amount of HPMC K4M leads to the less initial release and sustain effect. A theoretical drug release profile was generated using pharmacokinetic parameters of Colchicine. The value of t50 and t80 of theoretical drug release profile was found to be 242 min and 529 min respectively. The similarity factor f2 was applied between the in vitro drug release profile of optimizing batches and theoretical profile, which indicate a decent similarity between all in vitro drug release profiles (f2 = 68.28 for F7). All the batches except F1shows the value of f2 value within a range. Batch F7 showed the highest f2 (f2 = 68.28) among all the batches and this similarity was also reflected in t50 (≈ 256 min) and t80 (≈ 554 min) values. A 23 full factorial design was applied to systemically optimize in vitro drug release profile. The HPMC K4M (X1), Concentration of HPMC K100 M (X2), and concentration of EC (X3) were selected as independent variables. The time required for 50% drug released (t50), the time required for 80% drug release (t80), similarity factor f2, and mean dissolution time (MDT) were selected as dependent variables. The results of full factorial design indicate that the HPMC K4M (X1), Concentration of HPMC K100 M (X2), and concentration of EC (X3) have a significant effect on in vitro drug release profile. To find out the release mechanism the in vitro release data were fitted in the Korsmeyer-Peppas equation. All Batches except F1 and F3 show Anomalous diffusion-controlled release (combined mechanism of diffusion and case II transport).

E1 consisted of 2 control lots (3 males and 3 females), and 1 experimental lot (2 males and 1 female). E2 comprised 7 batches of rabbits (2 males and 1 female). E3 consisted of 2 batches of 3 females. Naja nigricollis venom was injected for approximately 20-30 minutes to the animals in the experimental batch of E1, and to those in E2 and E3. Then, E2 and E3 were treated preventively and curatively with minerals, respectively. After the determination of their biochemical and hematological parameters, they were necropsied separately and then their organs were removed, weighed and their appearance was studied. The study revealed that the venom of Naja nigricollis was the cause of death of all the animals of the experimental batch of E1. On the other hand, the use of P2 and P3 as a preventive measure was able to save 1 out of 3 and 3 individuals respectively from the venom. As for P3 as a curative measure, it kept alive 2 out of 3 individuals against the venom. Thus, for the development of anti-venomous phytomedicine, it would be advisable to use the minerals from P3 (ash of Millettia pinnata).

Published: November 2021

Most fruits and vegetables contain flavonoids, a type of phytonutrient. As well as carotenoids, they're responsible for fruits and vegetable brilliant hues. Some other phytonutrients such as flavonoids are strong antioxidants with anti-inflammatory and immune properties. There are many flavonoids, including anthocyanins, flavones, flavonols, flavonoids, and isoflavonoids. Quercetin and chrysin were chosen for the investigation. Humans and other animals can contract Helminthiasis (helminthiases), sometimes known as worm infection. Tapeworms, roundworms, and flukes are only a few of the parasites that exist. Skeletal muscle relaxants are used to treat spasticity caused by upper motor neuron syndromes and muscle discomfort or musculoskeletal spasms created by peripheral disturbances. Samples of quercetin and chrysin were generated in the presence of 0.5% SCMC suspension at concentrations of 10, 20, 30, and 40 mg/ml, and then analyzed. To keep track of photocell beam disruptions, a six-digit counter was utilized (locomotor activity). It was time to turn on the actophotometer and examine the locomotor behavior of each rat for five minutes. The basal activity levels of all the animals were recorded.

A Review on Complications of Sleep Apnea
Authors: DAVID JOHN , Jose Cindy , Venkateswaramurthy N , Sambath Kumar R
Published: November 2021

Sleep apnea occurs when the upper airway repeatedly becomes blocked during sleep, reducing or entirely blocking airflow. This is referred to as obstructive sleep apnea. If the brain fails to provide the necessary impulses for breathing, the disease is known as central sleep apnea. Sleep apnea and other sleep breathing problems are a leading cause of medical, social, and occupational disability. Sleep apnea is also linked to pulmonary hypertension, cardiac arrhythmia and other neurocognitive effects, majority of individuals with sleep apnea go undetected, putting them at danger during surgery. It is critical to identify these patients so that relevant steps can be implemented as soon as possible. In this review article, we will discuss about sleep apnea issues and their possible causes.

Forecasting floral futures: leveraging genetic and microenvironmental data to improve seed provenancing under climate change
Authors: Putra Andhika , Yen Jian , Fournier-Level Alexandre
Published: November 2021

Revegetation projects seeking to restore degraded ecosystems face a
major challenge in sourcing appropriate plant material, as identifying
plants adapted to future climates requires knowledge of plant
performance under novel conditions. In order to support
climate-resilient provenancing efforts, we develop a quantitative trait
model that integrates genetic and microenvironmental variation. We train
our model with multiple natural plantings of Arabidopsis thaliana and
predict days-to-bolting and fecundity across the species’ European
range. Model prediction accuracy was high for days-to-bolting and
moderate for fecundity, with the majority of trait variation being
explained by temperature variation. Concerningly, fecundity was
predicted to decline under future conditions, although this response was
heterogeneous across regions, and could be offset through the
introduction of specific genotypes. Our study highlights the value of
predictive models to aid seed provenancing and improve the success of
revegetation projects.
Adjusting growth standards for fetal sex improves correlation of small babies with stillbirth and adverse perinatal outcomes: A state-wide population study
Authors: Pritchard Natasha , Walker Susan , Tong Stephen , Lindquist Anthea C.
Published: November 2021

Objective: Identify the proportion of infants reclassified if
sex-specific birthweight charts were used, and if this reclassification
has an impact on the correlation between birthweight centile and adverse
perinatal outcome. Design: Retrospective cohort study Setting: Victoria,
Australia. Population: All infants born from 2005-2015 (529,261)
Methods: We applied GROW centiles, either adjusted or unadjusted for
fetal sex. We compared proportions of small for gestational age (SGA,
<10th centile) infants, then the populations of males
considered small only by sex-specific charts and females considered
small only by unadjusted charts. Main Outcome Measures: Stillbirth,
combined perinatal mortality, NICU admissions, Apgars <7 at 5
minutes, emergency caesarean sections. Results: Of those <10th
centile by unadjusted charts, 39.6% were male, and 60.5% female. Using
sex-specific charts, 50.3% <10th centile were male and 49.7%
female. 9,449 (19.2%) females that were SGA according to unadjusted
charts were appropriate for gestational age
(AGA,>10th-<90th centile) using sex-specific
charts. These reclassified newborn females were not at increased risk of
adverse outcomes compared with an AGA infant, but were at increased risk
of being iatrogenically delivered for suspected growth restriction (RR
4.90, 95%CI 4.39–5.48). 8,048 male infants were reclassified as SGA by
sex-specific charts (25% SGA increase). Compared with AGA infants,
these reclassified male newborns were at greater risk of stillbirth (RR
1.94, 95%CI 1.30-2.90) and all other adverse perinatal outcomes.
Conclusions: Sex-specific growth standards classify a new high-risk
cohort of male infants as SGA, and exclude a cohort of females, whose
risk is no greater than appropriately grown infants.

The association between diet and acne is of growing concern. Every country has its own food culture; however, only a few studies have surveyed the influence of Asian cuisine on acne. This study investigated the association between acne severity and diet/lifestyle factors in 2,467 Thai adolescents and adults. Data were collected via a validated semi-quantitative food frequency questionnaire. In Thai adolescents and adults, the prevalence of mild acne was 52%, moderate acne 22%, and severe acne 8%. No acne was found in 18% of participants. The dietary factors associated with increased severity of acne were consumption of chocolate >100 g/week (adjusted odds ratio (aOR) 1.29; 95% CI 1.07–1.56), oily and fried food >3 times/week (aOR 1.84; 95% CI 1.07–3.16) and white rice (aOR 1.80; 95% CI 1.24–2.63). Conversely, the factors associated with decreased severity of acne were consumption of sugar-free milk-free tea (aOR 0.61; 95% CI 0.43–0.87) and vegetables (aOR 0.74; 95% CI 0.62–0.89).
