Changes in sleep behavior, sleep problems, and psychological distress/health-related quality of life of young Japanese individuals before and during the COVID-19 pandemic

ABSTRACT Social restrictions during the coronavirus disease (COVID-19) pandemic have impacted sleep behavior and sleep problems, and their related daytime functioning in young adults. However, no studies have examined such changes in young individuals from countries with mild infection intensity and social restrictions. Therefore, we focused on sleep behaviors and sleep issues in young people in Japan. This study was conducted before and after the pandemic (October 2019 and May 2020, respectively). In total, 2,222 (1,371 students and 851 workers) individuals participated and completed anonymous Web-based questionnaires concerning demographic characteristics, sleep behaviors, sleep problems using the Japanese version of the Epworth Sleepiness Scale (JESS) and the Athens Insomnia Scale (AIS-J), psychological distress using the Japanese version of the Kessler Psychological Distress Scale, and health-related quality of life (HRQoL) evaluated with the Short Form-8 (SF-8). A significantly delayed sleep phase was observed in the second survey compared to the first (p < .001) and was more pronounced in students than in workers (p < .001). The total sleep time, social jetlag degree, and JESS, AIS-J, and SF-8 scores were significantly improved after the pandemic (p < .001, p < .001, p < .001, p < .001, p < .05, and p < .001, respectively). Careful monitoring of whether these modest changes can lead to adjustment concerns is needed.
Exploring Heterogeneity of Stepped Collaborative Care Treatment Response Trajectories after Adolescent Sports Injury Concussion

Objective: Few clinical trials of posttraumatic interventions have utilized symptom trajectory modeling to explore heterogeneity of treatment responses. The goal of this investigation was to conduct a secondary analysis of a randomized clinical trial of stepped collaborative care for adolescents with sports and recreational related concussion and persistent symptoms of >1 month. Method: Trajectory modeling was used to examine the impact of randomization to the intervention as well as demographic, clinical, and injury characteristics on adolescent post-concussive symptom trajectories. Two hundred male and female adolescents were assessed >1 month after a concussion, and then 3-, 6- and 12-months later with a standardized measure of concussive symptoms, the Health and Behavior Inventory (HBI). Multinomial logistic regression was used to compare the association between intervention, demographic, clinical and injury characteristics with trajectory group membership. Results: Four post-concussive symptom trajectories emerged: recovery, remitting, low-persistent, and high-persistent. In adjusted analyses randomization to the intervention condition was associated with significantly greater odds of HBI recovery trajectory group membership (OR 3.29 95% CI 1.06–10.28). Female gender and prior concussion history were associated with significantly greater odds of high-persistent trajectory group membership relative to all other trajectories. Greater odds of high-persistent versus recovery group trajectory membership was observed for adolescents with a pre-injury history of anxiety and/or depressive disorders. Conclusions: Stepped collaborative care was associated with an increased odds of recovery versus high-persistent post-concussive symptom trajectories, while readily identifiable baseline characteristics were associated high-persistent symptoms. Future post-concussive clinical trials and practice improvement efforts could incorporate these observations.
Health Impact Associated with Pesticides Use among Vegetables Farmers in Nepal: A Secondary Analysis.

ackground: The trend of pesticide use in market-oriented vegetables is steadily increasing in Nepal. Farmers in developing countries use hazardous pesticides taking few or no safety measures. This study is aimed to assess health effects of pesticide exposure among vegetable farmers in Nepal. METHODS Analysis of secondary data obtained from Nepal Health Research Council was performed. A cross-sectional study on "Health Effects of pesticide among vegetables farmers and adaptation level of integrated pest management program in Nepal 2013" was conducted by Nepal Health Research Council among 660 farmers in four selected districts of Nepal in 2013/2014. The secondary data obtained were statistically analyzed by student's't' test, one-way analysis of variance and Pearson correlation statistics. For all tests used, 5% level of significance was considered. RESULTS Fungicide and insecticides were commonly used pesticides by vegetable farmers in Nepal. Around 51% of the pesticides used were moderately hazardous (II) while, 28% were highly hazardous (Ib). Nearly 12% participants did not use any type of Personal Protective Equipments while spraying pesticides in the field. The prevalence of self-reported poisoning and low Acetylcholinesterase levels among farmers was 51% and 10.3% respectively. Acetylcholinesterase level was found to differ significantly in male as compared to female (P < .05). CONCLUSIONS Almost half of the research participants had self-reported poisoning. Low prevalence of depressed Acetylcholinesterase levels was associated with high use of fungicide compared to organophosphate.
Investigating service users' perspectives of eating disorder services: A meta‐synthesis

Abstract Objective Despite a number of qualitative studies published from the perspective of eating disorder (ED) service users, there has been no attempt to exclusively synthesize their views to gain a fuller understanding of their ED service experiences. It is important to understand this perspective, since previous research highlights the difficulties ED healthcare professionals report when working with this client group. Method A systematic search of the literature was conducted to identify qualitative studies focusing on experiences of ED services from the perspective of service users. Twenty‐two studies met the inclusion criteria and underwent a quality appraisal check using the Critical Appraisal Skills Programme (CASP) tool for qualitative research. These were then synthesized using a meta‐synthesis approach. Results Four overarching themes were generated: “Treatment: Focus on physical vs. psychological symptoms”; “Service Environment: The role of control within services”; “Staff: Experiences with staff and the value of rapport”; and “Peer Influence: Camaraderie vs. comparison. ” Service users expressed a desire for more psychological input to tackle underlying difficulties relating to their ED. A complex relationship with feelings of control was described, with some feeling over‐controlled by service providers, while others retrospectively recognized the need for control to be taken away. Staff values, knowledge and trust played a significant role in treatment and recovery. Peers with an ED were described to be a valuable source of understanding and empathy, but some found peer influence to perpetuate comparison and competitiveness. Discussion The results portray some of the conflicts and complexities that service users encounter in ED services. A running thread throughout is the perceived importance of adopting an individualized approach within these services.
Cancer in twin pairs discordant for smoking: The Nordic Twin Study of Cancer

The discordant twin pair study design is powerful to control for familial confounding. We employed this approach to investigate the associations of smoking with several cancers. The NorTwinCan study combines data from the Danish, Finnish, Norwegian and Swedish twin and cancer registries. Follow‐up started when smoking status was determined and ended at cancer diagnosis confirmed by information in the cancer registry, death or end of follow‐up. We classified the participants as never (n = 59 093), former (n = 21 168) or current (n = 47 314) smokers. We pooled data from twin pairs where one co‐twin was diagnosed with any of the following tobacco‐related cancers: esophagus, kidney, larynx, liver, oral cavity, pancreas, pharynx or urinary bladder, while their co‐twin had none of those. Lung cancer was included in further analysis. We used Cox regression allowing for pair‐specific baseline functions to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). For tobacco‐related cancer sites, we recorded 7379 cases during median 27 years of follow‐up. The analyses based on individual twins showed that former (HR 1.31, 95% CI: 1.17‐1.48) and current (HR 2.14 [1.95‐2.34]) smokers are at increased risk to develop one of cancers listed above, compared to never smokers. Among 109 monozygotic twin pairs discordant for cancer and smoking, the HR was 1.85 (95% CI: 1.15‐2.98) among current smokers and 1.69 (1.00‐2.87) among former smokers when compared to their never smoking co‐twin. Thus, associations of smoking with several cancers were replicated for discordant identical twin pairs. Analyses based on genetically informative data provide evidence consistent with smoking causing multiple cancers.
Extended application of the rapid post‐mortem test kit for bovine spongiform encephalopathy to chronic wasting disease

Chronic wasting disease (CWD) is a prion disease affecting cervid species primarily in the United States of America and Canada; however, it is now emerging in Scandinavian countries. Although CWD cases have not been reported in Japan, in case of a CWD outbreak occuring, it is critical to prepare for testing a large number of specimens. The present study showed that a rapid post‐mortem test kit, which is used for bovine spongiform encephalopathy surveillance in Japan, is valid for the detection of CWD prion.
Non-human primate pluripotent stem cells for the preclinical testing of regenerative therapies

Non-human primates play a key role in the preclinical validation of pluripotent stem cell-based cell replacement therapies. Pluripotent stem cells used as advanced therapy medical products boost the possibility to regenerate tissues and organs affected by degenerative diseases. Therefore, the methods to derive human induced pluripotent stem cell and embryonic stem cell lines following clinical standards have quickly developed in the last 15 years. For the preclinical validation of cell replacement therapies in non-human primates, it is necessary to generate non-human primate pluripotent stem cell with a homologous quality to their human counterparts. However, pluripotent stem cell technologies have developed at a slower pace in non-human primates in comparison with human cell systems. In recent years, however, relevant progress has also been made with non-human primate pluripotent stem cells. This review provides a systematic overview of the progress and remaining challenges for the generation of non-human primate induced pluripotent stem cells/embryonic stem cells for the preclinical testing and validation of cell replacement therapies. We focus on the critical domains of (1) reprogramming and embryonic stem cell line derivation, (2) cell line maintenance and characterization and, (3) application of non-human primate pluripotent stem cells in the context of selected preclinical studies to treat cardiovascular and neurodegenerative disorders performed in non-human primates.
Systemic Markers in Ophthalmic Manifestations of Post Corona Virus Disease-19 (COVID-19)

ABSTRACT Introduction Corona virus disease (COVID-19) has been associated with ophthalmic manifestations which can occur during or following the infection. Purpose To explore the systemic status in ophthalmic patients who had a recent history of COVID-19 or those with positive COVID-19 antibody status. Methods Retrospective case series. Results 30 patients with history of COVID-19 infection and positive COVID-19 antibodies were included in the study. The median age was 49 years (mean 48.7 ± 13.7 years), 20 were males (66.7%) and 10 (33.3%) were females. Patients with VA>/= 6/60 were included in group 1 and those with VA<6/60 were included in group 2. D-dimer/serum Ferritin levels were raised in group 2 compared to group 1with (p=0.013)/(p=0.018) respectively. Conclusion Serum D-dimer and ferritin levels were statistically significant and were higher in patients with sight threatening ocular manifestations. ESR and CRP were raised even after recovery from COVID-19 although they were not statistically significant.
Tractostorm 2: Optimizing tractography dissection reproducibility with segmentation protocol dissemination

The segmentation of brain structures is a key component of many neuroimaging studies. Consistent anatomical definitions are crucial to ensure consensus on the position and shape of brain structures, but segmentations are prone to variation in their interpretation and execution. White‐matter (WM) pathways are global structures of the brain defined by local landmarks, which leads to anatomical definitions being difficult to convey, learn, or teach. Moreover, the complex shape of WM pathways and their representation using tractography (streamlines) make the design and evaluation of dissection protocols difficult and time‐consuming. The first iteration of Tractostorm quantified the variability of a pyramidal tract dissection protocol and compared results between experts in neuroanatomy and nonexperts. Despite virtual dissection being used for decades, in‐depth investigations of how learning or practicing such protocols impact dissection results are nonexistent. To begin to fill the gap, we evaluate an online educational tractography course and investigate the impact learning and practicing a dissection protocol has on interrater (groupwise) reproducibility. To generate the required data to quantify reproducibility across raters and time, 20 independent raters performed dissections of three bundles of interest on five Human Connectome Project subjects, each with four timepoints. Our investigation shows that the dissection protocol in conjunction with an online course achieves a high level of reproducibility (between 0.85 and 0.90 for the voxel‐based Dice score) for the three bundles of interest and remains stable over time (repetition of the protocol). Suggesting that once raters are familiar with the software and tasks at hand, their interpretation and execution at the group level do not drastically vary. When compared to previous work that used a different method of communication for the protocol, our results show that incorporating a virtual educational session increased reproducibility. Insights from this work may be used to improve the future design of WM pathway dissection protocols and to further inform neuroanatomical definitions.
Cerebrovascular Disease Mortality after occupational Radiation Exposure among the UK National Registry for Radiation Workers Cohort

Exposure to ionizing radiation can damage the cerebrovascular system, however there is uncertainty regarding the effects after chronic exposure to low doses of radiation, such as that experienced by the public and those occupationally exposed. This study uses data from the UK National Registry for Radiation Workers cohort to assess the association between low-dose exposure to external radiation and cerebrovascular disease (CeVD) mortality. Poisson regression was used to estimate the Excess Relative Risk of CeVD mortality per Sievert (ERR/Sv) of radiation exposure. Estimates were obtained for all CeVD combined, ischemic stroke, hemorrhagic stroke and other/ill-defined CeVD. Results were adjusted for attained age, calendar period, sex, employer, industrial category and employment length. 166,812 nuclear workers (3,665,413 person-years) were included. By the end of 2011, 23% were dead including 3,219 deaths with an underlying cause of CeVD. The ERR/Sv for all CeVD deaths was 0.57 (95% CI: 0.00, 1.31; p = 0.05). Increased CeVD mortality rates were observed after doses as low as 10–20 mSv. However, a linear-exponential model fit the data significantly better than a linear model (p = 0.02). In the sub-type analyses, no evidence of linear associations were observed, however the patterns of response appeared to differ and there was some suggestion of an increased risk of hemorrhagic stroke at lower doses. These results are broadly consistent with other occupational cohort studies and suggest external radiation exposure may increase CeVD risk at lower doses than current ICRP protection guidelines suggest. Exploration of factors driving the observed dose-response shape, the potential impact of the healthy worker survivor effect, and further studies of cohorts with data on other potential confounders would be valuable.
Validation of parental stress scale in a Greek sample of mothers with infants from 0 to 12 months.

Parenting an offspring is a rewarding, albeit challenging task, often accompanied by high levels of stress. It is important to accurately assess the stress associated with parenting, as severe forms of stress may affect the parent-child dyad and lead to poor child outcomes. The aim of this study was to translate and validate the Parental Stress Scale (PSS) in the Greek population. We implemented forward and back translation and conducted a pilot test. A total of 735 mothers (Mage = 34.6) with infants aged 0-12 months completed the PSS, the Edinburgh Postnatal Depression Scale, and the Hospital Anxiety and Depression Scale. The Greek PSS-18 showed good internal consistency (Cronbach's α = .83) and adequate convergent validity. Results of exploratory and confirmatory factor analysis revealed two underlying factors: positive aspects of parenting and negative aspects of parenting. Our data confirm the validity of the Greek version of the PSS-18 in mothers with infants aged 0-12 months. The Greek version of the PSS-18 could be a useful tool for professionals and researchers who are interested in perinatal period and the aspects of parenthood.
Changes in medial-to-lateral knee joint loading patterns assessed by Dual-Energy X-ray Absorptiometry following supervised neuromuscular exercise therapy and patient education in patients with knee osteoarthritis: an exploratory cohort study

ABSTRACT Background The mechanisms underlying pain reductions following exercise therapy in patients with knee osteoarthritis (OA) are poorly understood. One mechanism could be changes in mechanical knee joint loading. Objective To investigate if a neuromuscular exercise therapy and patient education intervention could alter knee joint loading assessed by Dual-Energy X-ray Absorptiometry (DXA) in people with knee OA. Methods Participants with symptomatic knee OA were evaluated before and 26 weeks after an 8-week supervised neuromuscular exercise therapy and patient education intervention (Good Life with OsteoArthritis in Denmark). DXA scans were used to estimate the medial-to-lateral tibial plateau bone mineral density (BMD) ratio. The Knee Injury and Osteoarthritis Outcome Score was used to assess improvements in knee pain, symptoms, physical function, and knee-related quality of life. Changes in physical function were assessed with the 30-second chair stand test and the 40-meter fast paced walk test. Results Of 42 participants recruited, 30 (21 females, mean age 64 7.9 years) had full data available. Medial-to-lateral tibial BMD ratio increased non-significantly by 0.02 (95% CI −0.01 to 0.06) (indicating higher medial load) from baseline to 26-weeks follow-up. Participants had statistically significant improvements of 21% in pain, 17% in symptoms, 14% in ADL, 17% in knee-related quality of life, 13% in chair stand ability, and 6% in walking speed. Conclusions In this exploratory cohort study, following an 8-weeks supervised exercise therapy and patient education intervention, the medial-to-lateral tibial BMD ratio did not seem to change.
Predicting Cancer Lymph-Node Metastasis From LncRNA Expression Profiles Using Local Linear Reconstruction Guided Distance Metric Learning

Lymph-node metastasis is the most perilous cancer progressive state, where long non-coding RNA (lncRNA) has been confirmed to be an important genetic indicator in cancer prediction. However, lncRNA expression profile is often characterized of large features and small samples, it is urgent to establish an efficient judgment to deal with such high dimensional lncRNA data, which will aid in clinical targeted treatment. Thus, in this study, a local linear reconstruction guided distance metric learning is put forward to handle lncRNA data for determination of cancer lymph-node metastasis. In the original locally linear embedding (LLE) approach, any point can be approximately linearly reconstructed using its nearest neighborhood points, from which a novel distance metric can be learned by satisfying both nonnegative and sum-to-one constraints on the reconstruction weights. Taking the defined distance metric and lncRNA data supervised information into account, a local margin model will be deduced to find a low dimensional subspace for lncRNA signature extraction. At last, a classifier is constructed to predict cancer lymph-node metastasis, where the learned distance metric is also adopted. Several experiments on lncRNA data sets have been carried out, and experimental results show the performance of the proposed method by making comparisons with some other related dimensionality reduction methods and the classical classifier models.
Intertwined spin, charge, and pair correlations in the two-dimensional Hubbard model in the thermodynamic limit

Significance The high-temperature superconducting cuprates are governed by intertwined striped magnetic and charge orders, in addition to superconductivity. Remarkably similar behavior has also been seen in numerical calculations for the Hubbard model describing the copper–oxygen layers in these materials. Finite-cluster methods typically find that spin- and charge-stripe order dominates, while embedded quantum-cluster methods, which access the thermodynamic limit, often conclude that superconductivity does. Here, we report the observation of fluctuating spin and charge stripes in an embedded cluster calculation for the Hubbard model. This discovery demonstrates that striped states survive in the thermodynamic limit and allows us to study their influence on the model’s superconducting properties, where we find evidence for pair-density-wave correlations intertwined with the stripe correlations. The high-temperature superconducting cuprates are governed by intertwined spin, charge, and superconducting orders. While various state-of-the-art numerical methods have demonstrated that these phases also manifest themselves in doped Hubbard models, they differ on which is the actual ground state. Finite-cluster methods typically indicate that stripe order dominates, while embedded quantum-cluster methods, which access the thermodynamic limit by treating long-range correlations with a dynamical mean field, conclude that superconductivity does. Here, we report the observation of fluctuating spin and charge stripes in the doped single-band Hubbard model using a quantum Monte Carlo dynamical cluster approximation (DCA) method. By resolving both the fluctuating spin and charge orders using DCA, we demonstrate that they survive in the doped Hubbard model in the thermodynamic limit. This discovery also provides an opportunity to study the influence of fluctuating stripe correlations on the model’s pairing correlations within a unified numerical framework. Using this approach, we also find evidence for pair-density-wave correlations whose strength is correlated with that of the stripes.
