Published: January 2023

Most fluorescent imaging systems use pre-defined filter sets with limited flexibility in the choice of excitation and emission bands and suffer from crosstalk between different fluorophores for multiplexed imaging. When implemented in the context of optical fibers for biological imaging in a remote setting with space constraints, the size of the fiber probe is crucial. To overcome these challenges, we combined the merits of hyperspectral imaging and an ultrathin optical imaging fiber where fluorescent images at 311 spectral bands in the visible range were captured using a liquid crystal tunable filter with a fiber probe of 500 μm in diameter. Fluorescent experiments were performed on quantum dots mixtures and genetically modified E. coli bacteria mixtures to demonstrate the system’s capabilities for multiplexed imaging. Images were first processed using a Fourier transform filtering technique to remove the fiber core pattern artifact. Subsequently, the classification of different types of bacteria samples was calculated using two methods, namely, spectral unmixing with maximum abundance and spectral matching with minimum spectral angle distance. Finally, the spatial distributions of individual bacteria types were overlaid with the mixture image, and the two classification results matched well. A simple-to-use graphic user interface (GUI) platform for the hyperspectral imaging fiber probe system was developed which performs image processing and displays the classification results. The methods and results presented will appeal to the optical fiber-based imaging and hyperspectral imaging communities in general and have great potential for biological imaging applications.

Published: January 2023

BackgroundPrevious studies have revealed that religious coping strategy is common among athletes due to the stressful experiences before and during competitions as part of the mental preparations they go through, the uncertainty of sporting outcomes, and other organizational issues they encounter. This research assessed the reproducibility of the Brief Religious Coping (RCOPE) instrument in an African setting using athletes’ samples from different countries. Particularly, the research sought to assess the (1) factor structure of Brief RCOPE with an African sample, (2) construct validity of the RCOPE measure, and (3) measurement invariance of the RCOPE instrument based on gender and nationality.MethodsThe study surveyed a convenient sample of 300 athletes, including 164 male and 136 female athletes, from 3 African countries (Benin, Ghana, and Nigeria) who participated in the 2018 West African University Games. The Brief RCOPE instrument was administered to the athletes for validation purposes before the competition. Exploratory and confirmatory factor analyses were conducted using the ordinal factor analytic approach.ResultsThis validation study confirmed the two-factor dimension (positive and negative religious coping) of the Brief RCOPE measure. Further, all items for each of the dimensions of the inventory contributed significantly to the measure of the Brief RCOPE domains. The positive and negative religious coping dimensions contributed more than half of the variance of their respective indicators. Measurement invariance across gender and nationality was confirmed.ConclusionSufficient evidence was gathered to support the interpretation and use of the Brief RCOPE measure. Coaches and sports psychologists could adopt the Brief RCOPE measure to understand the mental or thought patterns of religious athletes based on existential concerns or stress accrued from impending competitions to inform appropriate religious coping interventions. This notwithstanding, the Minimum Clinical Important Difference (MCID) of the Brief RCOPE should be further investigated to enhance the utility of the instrument for use in intervention-based studies.

BackgroundTo date, conflict is causing extreme social crises worldwide, with children representing the most vulnerable group, often experiencing severe trauma and violence in conflict-ridden areas. Posttraumatic stress disorders (PTSDs) are the most widely reported psychological problem in the aftermath of conflict. However, less attention has been given to children living in conflict-prone areas of the world.ObjectiveThe present study aimed to assess posttraumatic stress disorders among children and adolescents in conflict-affected zones of the Amhara region in Ethiopia from January to February 2022.MethodA community-based cross-sectional study was employed from January to February 2022. A multistage random sampling technique was employed to recruit the study participants. A structured interviewer-administered questionnaire was designed to collect the desired data. Data were verified, coded, and entered into EpiData version 3.1 and analyzed using SPSS version 24 statistical software.ResultA total of 846 children with a response rate of 94.33% were screened for trauma. Subsequently, 557 (69.80%) children had experienced trauma. Of these 557 children who had experienced trauma, 203 (36.45%) developed posttraumatic stress disorders. Based on these results, this study recommends that mass screening of children and adolescents for posttraumatic stress disorders and rehabilitation services be undertaken, including resilience training and psychosocial support.

IntroductionSubstantial research indicates that high quality early childhood education and care (ECEC) confers a wide range of benefits for children, yet quality in ECEC remains inconsistent. Given the variability in training and qualifications, one strategy for improving ECEC quality is in-service professional development (PD).MethodsThe current study evaluated an evidence-based in-service PD programme, Leadership for Learning, via a cluster randomised controlled trial involving 83 ECEC services and 1,346 children in their final year of pre-school.ResultsResults indicated significant improvements in teaching quality across treatment centres and child development outcomes in language, numeracy and social-emotional development.DiscussionThis study provides strong support for making evidence-informed PD routinely available for ECEC practitioners.

PurposeThis study aimed to investigate the effect of exercise intervention, and analyze exercise intervention strategies for adolescent depression through a meta-analysis of RCTs.MethodsAccordance to PRISMA guidelines, PubMed, Medline, EBSCO, Web of Science, SPORTDiscus, PsycINFO, ProQuest, and CNKI were searched for eligible records. Peer-reviewed studies were included if they met the following criteria: population (mean age of 10–18 years), intervention (physical activity, sport, or exercise), and outcomes (depression, adherence, ITT, dropout, adverse events, follow-up report). The protocol of this systematic review was registered in PROSPERO (CRD42022321683). Effect sizes calculations and methodological quality of exercise intervention (TESTEX scale) were carried out. The certainty of evidence was assessed by GRADE framework.ResultsThirteen randomized controlled trials were eligible for this review, which comprised a total of 433 adolescents. Compared with the control treatment, the effect of exercise on adolescent depression was moderate (SMD = −0.65, 95%CI: −1.03 to −0.27, p &lt; 0.01). Heterogeneity was substantial (T2 = 0.30, I2 = 67%, p &lt; 0.01). The moderating effect analysis showed that exercise intervention characteristics (organization form, exercise frequency, exercise intensity, exercise type, and single exercise session duration) of included studies varied greatly revealing multiple factors that may impact the antidepressant effect of exercise on adolescent depression (I2 &gt; 50%, p &lt; 0.05). Three studies show that the positive effect of exercise on reducing depression in adolescents remained 40 weeks after the intervention. Moreover, owing to the included studies contained methodological limitations, the certainty of evidence was reduced to moderate level.ConclusionThis study shows that exercise intervention has a moderate and sustained positive effect on adolescent depression. Our results recommended that adolescents with depression undertake moderate to high intensity group mixed exercise for more than 12 weeks, 20 to 60 min/time, more than 3 times/week. Additionally, our study also shows that the antidepressant effects remained for a long time after the end of exercise interventions. However, following the GRADE framework, we rated the certainty of evidence the primary meta-analysis as moderate evidence due to some limitations of included studies. Therefore, rigorous studies are still needed to verify the results.Systematic review registration[https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=321683], identifier [CRD42022321683].

Published: January 2023

BackgroundIn crises, it is of great relevance to identify mechanisms that help people to maintain a certain level of wellbeing. This paper investigates whether appraising the COVID-19 pandemic as a threat vs. as a challenge has different effects on subjective wellbeing during the pandemic. Furthermore, we study the role of the perceived local environmental quality for individuals' subjective wellbeing.MethodsVia online survey study with two times of measurement (N = 758), we investigated (a) the prediction of participants' wellbeing in June 2020 and June 2021 through five variables and (b) how these five variables moderated within-participant differences in subjective wellbeing over time.ResultsResults showed that a stronger perception of the pandemic as a threat (feeling worried) and a lower education in June 2020 predicted a lower subjective wellbeing in 2020 and 2021. A stronger challenge appraisal (feeling confident), higher efficacy expectations, and positive perceptions of the local environmental quality in June 2020 predicted a higher wellbeing in 2020 and 2021. There was no substantial change in participants' aggregated wellbeing over time. However, those who perceived the pandemic more as a threat in June 2020 struggled more with negative changes in their wellbeing, whereas those who perceived the pandemic more as a challenge reported a higher wellbeing.ConclusionIt seems key to support people in activating positive feelings to successfully cope with crises.

IntroductionSuicide is a deliberate attempt to take one's own life. Suicidal behavior among adolescents and young people, a significant global public health issue, is under-researched, particularly in developing nations like Ethiopia. Therefore, this study aimed to assess the prevalence of suicide attempts and their determinants among school-aged and out-of-school youth in the central, north, and west Gondar zones of Ethiopia.MethodsA community-based cross-sectional study was conducted from 15 March to 15 April 2019, among youth in the central, north, and west Gondar zones. The data for this study were extracted from information collected for the assessment of common health problems and risky behaviors among youth. A multistage cluster sampling technique was used to collect the data using face-to-face interviewer-administered questionnaires. Bivariable and multivariable logistic regression analyses were done to identify the independent determinants of suicide attempts. An adjusted odds ratio (AOR) with a 95% confidence interval (CI) was used to identify the presence and direction of the association between the dependent and independent variables.ResultsA total of 1,597 youth participated in this study, and the mean age of the participants was 19.1 ± 2.8 standard deviations (SDs). The lifetime prevalence of suicide attempts in the study participants was 5.5% (95% CI: 4.4, 6.8%). Risky sexual practices (AOR = 1.89, 95%CI: 1.19–2.99), the presence of common mental health problems (AOR = 6.31, 95% CI: 3.78–10.88), having a personal income (AOR = 1.68, 95% CI: 1.05–2.71), and a history of violence (AOR = 2.81, 95% CI 1.76–4.49) were significantly associated with a suicide attempt.ConclusionIn this study, the prevalence of lifetime suicide attempts among youth is high. The presence of common mental health problems, having a personal income, risky sexual practices, and a history of violence increase the likelihood of suicide attempts. Working on the reduction of risky sexual practices, ensuring the integration of psychological treatment into medical treatment programs for victims of violence, psychosocial support for young people, and integrating youth-friendly health services to promote mental health would help to reduce suicide attempts among youth.

Published: January 2023

ObjectiveThe number of citations to a paper represents the weight of that work in a particular area of interest. Several highly cited papers are listed in the bibliometric analysis. This study aimed to identify and analyze the 100 most cited papers in insomnia research that might appeal to researchers and clinicians.MethodsWe reviewed the Web of Science (WOS) Core Collection database to identify articles from 1985 to 24 March 2022. The R bibliometric package was used to further analyze citation counts, authors, year of publication, source journal, geographical origin, subject, article type, and level of evidence. Word co-occurrence in 100 articles was visualized using VOS viewer software.ResultsA total of 44,654 manuscripts were searched on the Web of Science. Between 2001 and 2021, the top 100 influential manuscripts were published, with a total citation frequency of 38,463. The top countries and institutions contributing to the field were the U.S. and Duke University. Morin C.M. was the most productive author, ranking first in citations. Sleep had the highest number of manuscripts published in the top 100 (n = 31), followed by Sleep Medicine Reviews (n = 9). The most cited manuscript (Bastien et al., Sleep Medicine, 2001; 3,384 citations) reported clinical validation of the Insomnia Severity Index (ISI) as a brief screening indicator for insomnia and as an outcome indicator for treatment studies. Co-occurrence analyses suggest that psychiatric disorders combined with insomnia and cognitive behavioral therapy remain future research trends.ConclusionThis study provides a detailed list of the most cited articles on insomnia. The analysis provides researchers and clinicians with a detailed overview of the most cited papers on insomnia over the past two decades. Notably, COVID-19, anxiety, depression, CBT, and sleep microstructure are potential areas of focus for future research.

Published: January 2023

ObjectiveThe objective of this study was to gain insight into patients' experiences of how personal recovery (PR) is facilitated or hindered in the context of an early episode psychosis setting (Soteria). We thereby aimed to contribute to the understanding of how care settings may promote or hinder the process of PR in people with (acute) psychosis.MethodThis study used a qualitative method, consisting of semi-structured in-depth interviews with people who had been admitted to a Soteria house in the Netherlands. Interview transcripts were analyzed following the Grounded Theory approach.ResultsFive themes emerged from the data illustrating how Soteria facilitated or impeded PR. The experience of togetherness in contact with staff and peers, feeling at home, and being active facilitated PR, while the emphasis put on medication by staff was experienced as hindering, and attention to spirituality was missed.ConclusionIn addition to the literature that identified factors associated with PR in psychosis, the current study gives a sense of how this can be put into practice. By offering treatment within a normalizing, holding environment, with emphasis on equality, close contact, optimism, active structured days, open-mindedness toward spirituality, and the role of medication, PR can be facilitated without detracting from guideline-based treatment aimed at symptomatic recovery. Similarities with existing concepts are discussed.

BackgroundInsufficient physical activity (IPA) is a significant risk factor for various non-communicable diseases. The Iran action plan is a 20% reduction in IPA. Therefore, we aimed to describe the age and sex pattern of physical activity domains, IPA, the intensity of physical activity, sedentary behavior, and their associates at Iran's national and provincial levels in 2021.MethodsThis study used the data of the STEPwise Approach to NCD Risk Factor Surveillance (STEPS) 2021 in Iran. The STEPS study used the Global Physical Activity Questionnaire (GPAQ) version two developed by WHO for the assessment of physical activity, which included work, transport, and recreational activities domains. We showed and compared demographic and clinical characteristics of participants between males and females, usingt-test and Chi-square test. A logistic regression model adjusted for residential areas, years of schooling, wealth index, age, marital status, and occupation has also been implemented. The results were presented as percentages and 95% confidence intervals (CI).ResultsWe included 27,874 participants with a mean (SD) age of 45.69 (15.91), among whom 12,479 (44.77%) were male. The mean prevalence of IPA for the whole population for all ages was 51.3% (50.62–51.98%). By sex, 41.93% (40.88–42.98%) and 57.87% (56.99–58.75%) of men and women had IPA, respectively. According to the physical activity domains, the age-standardized prevalence of no recreational activity was 79.40% (78.80–79.99%), no activity at work was 66.66% (65.99–67.32%), and no activity at transport was 49.40% (48.68–50.11%) for both sexes combined. Also, the overall age-standardized prevalence of sedentary behaviors was 50.82% (50.11–51.53%). Yazd province represented the highest prevalence of IPA (63.45%), while West Azerbaijan province represented the lowest prevalence (39.53%). Among both sexes, living in the urban area vs. rural area [adjusted OR: 1.44; (1.31–1.58)], married vs. single status [adjusted OR: 1.33; (1.16–1.53)], and wealth index of class 3 vs. class 1 [adjusted OR: 1.15; (1.01–1.30)] were significantly associated with a higher rate of IPA.ConclusionThe prevalence of IPA was considerably high in Iran. To achieve the predefined goal of reducing IPA, the health system should prioritize increasing physical activity, especially in urban areas and among females.

AimSleep disturbance was closely associated with an increased risk of psychotic-like experiences (PLEs). This study aims to explore the association between sleep disturbance and PLEs among urban adolescents with and without parental migration.MethodsA total of 67, 532 urban Chinese adolescents were recruited in a large web-based survey during April 21st to May 12th, 2021. In our study, sleep disturbance, PLEs, family function, school climate, and a series of socio-demographic were assessed. And hierarchical logistic regression analyses were performed to examine influential factors associated with PLEs.ResultsUrban left-behind children (LBC) had a higher prevalence of sleep disturbance and PLEs than non-LBC. After controlling for confounders, parental migration was associated to PLEs with weak significance (OR = 1.19). Meanwhile, sleep disturbance was found to be a robust risk factor for PLEs (OR = 3.84 and 4.09), with or without the effect of parental migration. In addition, better family function and school climate has significant association with decreased risk of PLEs.ConclusionAdolescents with sleep disturbance are more likely to report PLEs. Adolescents' PLEs preventive strategies could focus on reducing sleep disturbance related symptoms as well as improving family function and school climate.
