Gut microbial and clinical characteristics of individuals with autism spectrum disorder differ depending on the ecological structure of the gut microbiome. Psychiatry Res 2024; 335:115775. [PMID: 38503005 DOI: 10.1016/j.psychres.2024.115775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 01/30/2024] [Accepted: 02/05/2024] [Indexed: 03/21/2024]
Abstract
Understanding the relationship between the gut microbiome and autism spectrum disorder (ASD) is challenging due to the heterogeneous nature of ASD. Here, we analyzed the microbial and clinical characteristics of individuals with ASD using enterotypes. A total of 456 individuals participated in the study, including 249 participants with ASD, 106 typically developing siblings, and 101 controls. The alpha and beta diversities of the ASD, sibling, and control groups did not show significant differences. Analysis revealed a negative association between the Bifidobacterium longum group and the Childhood Autism Rating Scale, as well as a negative association between the Streptococcus salivarus group and the Social Responsiveness Scale (SRS) within the ASD group. When clustered based on microbial composition, participants with ASD exhibited two distinct enterotypes, E1 and E2. In the E2 group, the SRS score was significantly higher, and the Vineland Adaptive Behavior Scale score was significantly lower compared to the E1 group. Machine learning results indicated that the microbial species predicting SRS scores were distinct between the two enterotypes. Our study suggests that the microbial composition in individuals with ASD exhibits considerable variability, and the patterns of associations between the gut microbiome and clinical symptoms may vary depending on the enterotype.

Abstract
On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb et al. (Indirect Drive ICF Collaboration), Phys. Rev. Lett. 129, 075001 (2022)PRLTAO0031-900710.1103/PhysRevLett.129.075001]. This achievement is the culmination of more than five decades of research and gives proof that laboratory fusion, based on fundamental physics principles, is possible. This Letter reports on the target, laser, design, and experimental advancements that led to this result.

Children's and Parents' Factors That Affect Parenting Stress in Preschool Children With Developmental Disabilities or Typical Development. Psychiatry Investig 2023; 20:1157-1167. [PMID: 38163655 PMCID: PMC10758321 DOI: 10.30773/pi.2023.0223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Accepted: 09/08/2023] [Indexed: 01/03/2024] Open
Abstract
OBJECTIVE This study compared parenting stress in preschool children with developmental disabilities (DD) or typical development (TD). We also investigated children's factors that affect parenting stress. METHODS A total of 196 preschool children participated in the study (aged 54.8±9.2 months). There were 79 children with DD (59 with autism spectrum disorder, 61 with intellectual disability, 12 with language disorder) and 117 with TD. The high parenting stress and the low parenting stress groups were divided based on the Total Stress of Korean Parenting Stress Index Fourth Edition (K-PSI-4) with an 85-percentile cutoff score. Pearson's correlation analysis was conducted to calculate the correlation between K-PSI-4 and the children's or parents' measures. RESULTS The difference in parenting stress between DD and TD was significant in the Total Stress of K-PSI-4 (p<0.001). The Total Stress scale of K-PSI-4 represented a modest to strong correlation with cognitive development, adaptive functioning, social communication, and behavioral problems in children with DD. Our results showed that caregivers of children with DD reported higher parenting stress than those with TD. Parenting stress was strongly associated with cognitive development, adaptive functioning, social communication, and behavioral problems in children with DD. Among the children's factors, especially social communication, attention problems, and aggressive behavior had association with caregivers' higher parenting stress. CONCLUSION These findings suggest the need for early intervention for parenting stress in caregivers by assessing child characteristics, including social cognition, awareness, communication, and inattention and hyperactivity, in the evaluation of children with DD.

Factors in Parenting Stress in Young Patients With Breast Cancer and Implications for Children's Emotional Development: The PSYCHE Study. JAMA Netw Open 2023; 6:e2344835. [PMID: 38015505 PMCID: PMC10685886 DOI: 10.1001/jamanetworkopen.2023.44835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 10/06/2023] [Indexed: 11/29/2023] Open
Abstract
Importance The number of patients with breast cancer who have children is substantial. However, the emotional burden of this disease and its implication for childhood development remain largely unknown. Objective To investigate the clinical factors in parenting stress in mothers with breast cancer and the association of maternal depression and parenting stress with their children's emotional development. Design, Setting, and Participants This cross-sectional study involved a survey of females with stage 0 to 3 breast cancer and was conducted from June 2020 to April 2021 in Seoul, South Korea. Participants were aged 20 to 45 years and completed the Center for Epidemiologic Studies Depression-Revised scale and basic questionnaires on demographic and clinical characteristics. Participants with children completed the Korean Parenting Stress Index Short Form (K-PSI-SF), Child Behavior Checklist, Junior Temperament and Character Inventory, and Children's Sleep Habits Questionnaire. Exposure Having children in patients with breast cancer. Main Outcomes and Measures Multivariable logistic and linear regression analyses were performed to investigate the association between maternal depression and parenting stress. Results A total of 699 females (mean [SD] age, 39.6 [4.6] years) were included, of whom 499 had children (mean [SD] age of children, 8.0 [2.7] years). Depression was more common in patients with children (odds ratio [OR], 2.25; 95% CI, 1.01-5.05) and patients who had gonadotropin-releasing hormone treatment (OR, 1.68; 95% CI, 1.15-2.44). Disease duration was inversely associated with depression (OR, 0.85; 95% CI, 0.76-0.96). Cancer-related factors were not associated with the K-PSI-SF score. Having children aged 6 years or older (β = 3.09; 95% CI, 0.19-5.99); being the sole primary caregiver (β = -3.43; 95% CI, -5.87 to -0.99); and reporting certain temperament (eg, novelty seeking: β = 0.58; 95% CI, 0.46-0.71), emotional problems (eg, anxious/depressed: β = 8.09; 95% CI, 3.34-12.83), and sleeping pattern (eg, bedtime resistance: β = 0.57; 95% CI, 0.15-0.99) subscale scores in their children were associated with parenting stress. Depression and parenting stress were correlated (β = 0.56; 95% CI, 0.45-0.66; P < .001). The emotional challenges encountered by children of mothers with breast cancer were not significantly different from reference values. Conclusions and Relevance This study found that in patients with breast cancer, child-related factors and depression were significantly associated with parenting stress, but breast cancer-related factors were not correlated. The findings suggest that mothers with breast cancer are susceptible to both depression and parenting stress and that tailored counseling and support are needed.

Abstract
Objectives This study aimed to compare the utility of the Psychoeducational Profile-Revised (PEP-R), Korean Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (K-WPPSI-IV), and Vineland Adaptive Behavior Scale, Second Edition (VABS-II) for evaluating developmental disabilities (DD) in preschool children. Additionally, we examined the correlations between the PEP-R, KWPPSI- IV, and VABS-II. Methods A total of 164 children aged 37-84 months were assessed. Children's development was evaluated using the PEP-R, K-WPPSIIV, VABS-II, Preschool Receptive-Expressive Language Scale, and Korean Childhood Autism Rating Scale, Second Edition. Results Of the 164 children, 103 had typical development (TD) and 61 had DD. The mean of the PEP-R Developmental Quotient (DQ), K-WPPSI-IV Full-Scale Intelligence Quotient (FSIQ), and VABS-II Adaptive Behavior Composite (ABC) scores were significantly higher in the TD group than in the DD group (p<0.001). The estimated area under the curve of the PEP-R DQ, K-WPPSI-IV FSIQ, and VABS-II ABC scores was 0.953 (95% confidence interval [CI]=0.915-0.992), 0.955 (95% CI=0.914-0.996), and 0.961 (95% CI=0.932- 0.991), respectively, which did not indicate a statistically significant difference. The PEP-R DQ scores were positively correlated with the K-WPPSI-IV FSIQ (r=0.90, p<0.001) and VABS-II ABC scores (r=0.84, p<0.001). A strong correlation was observed between the KWPPSI- IV FSIQ and VABS-II ABC scores (r=0.89, p<0.001). Conclusion This study found that the PEP-R, K-WPPSI-IV, and VABS-II effectively distinguished DD from TD in preschool children, and no significant differences in utility were observed between them.

Early urodynamic findings after complete primary repair of exstrophy. J Pediatr Urol 2023; 19:565.e1-565.e5. [PMID: 37355344 DOI: 10.1016/j.jpurol.2023.05.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 05/25/2023] [Accepted: 05/29/2023] [Indexed: 06/26/2023]
Abstract
INTRODUCTION Detrusor contraction in bladder exstrophy (BE) patients following reconstruction is poorly understood as there are few published studies assessing urodynamic findings in this population. Understanding the ability of the detrusor to contract in BE patients early after closure may be able to inform the longer-term management and potential for the development of future continence in this population. OBJECTIVE We sought to evaluate early detrusor contraction using urodynamic studies (UDS) in children who had previously undergone complete primary repair of bladder exstrophy (CPRE). We hypothesized that a majority of children with BE would display the presence of normal detrusor contractile function after CPRE. STUDY DESIGN A retrospective review of our prospectively collected database was performed for all patients with a diagnosis of classic BE who underwent primary CPRE between 2013 and 2017. From this cohort we identified patients with at least one post-operative UDS at 3 years of age or older who had undergone an initial CPRE. Our primary outcome was the presence of a detrusor contraction demonstrated on UDS. RESULTS There were 50 children (31 male, 19 female) with CBE who underwent CPRE between 2013 and 2017.There were 26 (13 male, 13 female) who met inclusion criteria. Median age was 3.5 (IQR: 3.2-4.7) years at the time of UDS Sixteen of the 26 (61.5%) generated a sustained detrusor contraction generating a void, with a median peak voiding pressure of 38 cm H20 (IQR: 28-51). The median bladder capacity reached was 48 ml, which represented a median of 30% of expected bladder capacity. The median post void residual (PVR) for the entire cohort was 26 ml (IQR: 9, 47) or 51% (IQR: 20%-98%) of their actual bladder capacity, while the median PVR for those children with a sustained detrusor contraction was 18 ml (IQR: 5, 46) or 33% (IQR: 27%, 98%) of their actual bladder capacity. Intraoperative bladder width and bladder dome to bladder neck length did not correlate with the presence of voiding via a detrusor contraction (p = 0.64). DISCUSSION We present the first study assessing early UDS finding of detrusor contraction in BE patients after CPRE. In our cohort, 61.5% of patients were able to generate a sustained detrusor contraction on UDS which is a higher percentage than has been reported in previous series. A difference in initial surgical management may account for these findings. CONCLUSION At short term follow up, the majority of children in our cohort were able to produce sustained detrusor contractions sufficient to generate a void per urethra with a modest post void residual volume. Long-term follow-up and repeated UDS will be needed to track detrusor contractility rates, bladder capacities, compliance, post void residuals and ultimately continence rates over time.

Impact of Comorbid Oppositional Defiant Disorder on the Clinical and Neuropsychological Characteristics of Korean Children With Attention-Deficit/Hyperactivity Disorder. Psychiatry Investig 2023; 20:962-971. [PMID: 37899220 PMCID: PMC10620339 DOI: 10.30773/pi.2023.0091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 07/05/2023] [Accepted: 08/09/2023] [Indexed: 10/31/2023] Open
Abstract
OBJECTIVE The aim of the present study was to investigate the influence of comorbid oppositional defiant disorder (ODD) on clinical features and neuropsychological profiles of children with attention-deficit/hyperactivity disorder (ADHD). METHODS We divided the participants into three groups: the ADHD with ODD (ADHD/ODD) (n=36), ADHD without ODD (ADHD/noODD) (n=307), and control groups (n=128). Parents of the participants completed the ADHD Rating Scale, Social Responsiveness Scale (SRS), Korean Personality Rating Scale for Children (K-PRC), and 10-item mania scale from the Parent General Behavior Inventory (P-GBI-10M). Neuropsychological profiles were assessed using the Advanced Test of Attention (ATA), Children's Color Trails Test, and Stroop Color and Word Test. RESULTS The ADHD/ODD group had more ADHD symptoms and functional impairments in relationships with teachers and peers, and self-esteem than the ADHD/noODD group. The ADHD/ODD group scored higher in Social Communication (p<0.001) and Autistic Mannerisms (p<0.001) subscales of SRS, P-GBI-10M (p<0.001), and Delinquency (p<0.001) and Psychosis (p<0.001) subscales of K-PRC than the ADHD/noODD group. Commission Errors (p<0.001) and Response-Time Variability (p<0.001) in Visual ATA and Commission Errors (p<0.001) in Auditory ATA were significantly higher in the ADHD/ODD group than in the ADHD/noODD group. CONCLUSION The present study suggests that patients with ADHD with ODD experience more ADHD symptoms and neuropsychological deficits than those with ADHD without ODD. These results also imply that comorbid ODD is associated with greater social impairment and emotional dysregulation.

Childhood-Onset Lupus Nephritis in the Childhood Arthritis and Rheumatology Research Alliance Registry: Short-Term Kidney Status and Variation in Care. Arthritis Care Res (Hoboken) 2023; 75:1553-1562. [PMID: 36775844 PMCID: PMC10500561 DOI: 10.1002/acr.25002] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 07/14/2022] [Accepted: 08/16/2022] [Indexed: 11/10/2022]
Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Abstract
OBJECTIVE This study aimed to evaluate the association between media exposure to non suicidal self-injury (NSSI) and emergency department (ED) visits due to self-harm in Korea, specifically before and after the initial broadcast of the song Barcode, which has an explicit focus on NSSI. METHOD We used the national emergency department information system to obtain data related to ED visits due to self-harm between January 1, 2014, and December 31, 2018. Using interrupted time series regression analysis, we assessed the monthly ED visits due to self-harm before and after the media exposure to NSSI on March 30, 2018. In addition, self-harm methods were assessed. RESULTS A total of 35,928,834 visits to ED were identified, of which 115,647 were due to self-harm. ED visits due to self-harm showed a significant step increase in the 10- to 14-year-old (β = 0.883, p = .001), 15- to 19-year-old (β = 2.941, p < .001), 20- to 24-year-old (β = 1.997, p = 0.002), and 25- to 29-year-old (β = 1.438, p = .029) age groups, before and after the media exposure to NSSI. The most pronounced increase was observed in male participants aged 20 to 24 years (β = 1.790, p = .012) and female participants aged 15 to 19 years (β = 5.158, p < .001). Self-harm by cutting has increased significantly in participants aged 10 to 29 years, and self-harm by poisoning has also increased significantly in participants aged 10 to 19 and 25 to 29 years. CONCLUSION ED visits due to self-harm increased significantly, especially in adolescents and young adults, following the exposure to NSSI. Responsible media reporting on NSSI and appropriate guidelines would help prevent a further increase in self-harm.

Efficacy of Mobile-Based Cognitive Training Program DoBrain in Preschool Children With or Without Developmental Disabilities: A Randomized, Single-Blind, Active-Controlled Trial. Psychiatry Investig 2022; 19:1000-1011. [PMID: 36588434 PMCID: PMC9806509 DOI: 10.30773/pi.2022.0136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 09/29/2022] [Indexed: 12/24/2022] Open
Abstract
OBJECTIVE Mobile-based cognitive training programs can be a viable alternative to in-person interventions, but their efficacies have not been established yet. In this study, we examined the efficacy of DoBrain, a mobile-based cognitive training program designed for children with developmental disabilities (DDs), in comparison with general educational apps named Junior Naver and Kakao Kids. METHODS Children aged 34 to 77 months were recruited and randomized at a 1:1 ratio to use DoBrain or general educational apps. Each group used the assigned app on a daily basis at home for 30 minutes for 24 weeks. Parents were instructed to help the children with the app usage. A total of 166 children completed the post-test visit (DoBrain group, n=85, 55.4±8.7 months old; general educational app group, n=81, 53.7±9.9 months old). The primary outcome was cognitive development measured by Psychoeducational Profile-Revised (PEP-R), administered at baseline and at post-test. RESULTS DoBrain had no superior effect over general educational apps on the PEP-R Developmental Quotient. When the changes before and after app usage were compared, the DoBrain group and the general educational app group both showed declines in imitation (adjusted p=0.049 and 0.022), perception (adjusted p=0.004 and <0.001), and gross motor (adjusted p=0.003 and 0.002) domains of the PEP-R. Among the DoBrain group, children with DD showed a significantly greater gain in the eye-hand coordination domain of PEP-R compared with those without DD (adjusted p=0.047). CONCLUSION DoBrain did not show a superior effect over general educational apps on overall cognitive development in preschool children, regardless of the presence of DD. Careful monitoring of the negative effect of mobile-based cognitive training programs is necessary.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry. Pediatr Rheumatol Online J 2022; 20:107. [PMID: 36434731 PMCID: PMC9701017 DOI: 10.1186/s12969-022-00770-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 11/08/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

[PMID: 35933308 PMCID: PMC9356715 DOI: 10.1016/j.jsurg.2022.07.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Accepted: 07/13/2022] [Indexed: 05/11/2023]
Abstract
BACKGROUND Online education has been increasingly utilized over the past decades. The COVID-19 pandemic accelerated the transition of conventional face-to-face curricula to online platforms, with limited evidence for its teaching efficacy. This systematic review aims to assess the effectiveness of online video-based education compared with standard conventional education in teaching basic surgical skills to surgical trainees and students undergoing medical training. METHODS We performed a literature search in Embase, Medline, Cochrane CENTRAL and Scopus from inception until February 2022. Studies included were randomised controlled trials (RCTs) and observational studies. We included randomised controlled trials only for meta-analysis. The primary outcome was surgical skill proficiency. The secondary outcomes were participant perception, confidence and satisfaction. Two authors independently assessed the search results for eligibility, extracted the data and assessed the risk of bias using the Cochrane Risk of Bias tool 2. Where appropriate, we performed random effects meta-analyses of the pooled study data to calculate a standardized mean difference. RESULTS A total of 11 studies met the inclusion criteria totaling 715 participants; 603 were included in qualitative analysis and 380 in meta-analysis. All included studies were assessed as having a low risk of bias. The majority of studies found no significant difference between conventional and video-based education in teaching basic surgical skills, three studies found video-based education was superior and one study found conventional education was superior. There was no statistically significant difference in skill proficiency between the two groups (standardized mean difference of -0.02 (95% CI: -0.34, 0.30); p=0.90). Video-based education results in an equivalent improvement in confidence and satisfaction rates. Additional benefits of video-based education include convenience, accessibility and efficiency. CONCLUSIONS Basic surgical skills can be taught as effectively through online video-based education as conventional teaching methods. Online education should be utilized as an adjunct to medical curricula beyond the COVID-19 era.

Non-coding de novo mutations in chromatin interactions are implicated in autism spectrum disorder. Mol Psychiatry 2022; 27:4680-4694. [PMID: 35840799 DOI: 10.1038/s41380-022-01697-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 06/27/2022] [Accepted: 07/01/2022] [Indexed: 12/14/2022]
Abstract
Three-dimensional chromatin interactions regulate gene expressions. The significance of de novo mutations (DNMs) in chromatin interactions remains poorly understood for autism spectrum disorder (ASD). We generated 813 whole-genome sequences from 242 Korean simplex families to detect DNMs, and identified target genes which were putatively affected by non-coding DNMs in chromatin interactions. Non-coding DNMs in chromatin interactions were significantly involved in transcriptional dysregulations related to ASD risk. Correspondingly, target genes showed spatiotemporal expressions relevant to ASD in developing brains and enrichment in biological pathways implicated in ASD, such as histone modification. Regarding clinical features of ASD, non-coding DNMs in chromatin interactions particularly contributed to low intelligence quotient levels in ASD probands. We further validated our findings using two replication cohorts, Simons Simplex Collection (SSC) and MSSNG, and showed the consistent enrichment of non-coding DNM-disrupted chromatin interactions in ASD probands. Generating human induced pluripotent stem cells in two ASD families, we were able to demonstrate that non-coding DNMs in chromatin interactions alter the expression of target genes at the stage of early neural development. Taken together, our findings indicate that non-coding DNMs in ASD probands lead to early neurodevelopmental disruption implicated in ASD risk via chromatin interactions.

Abstract
Abstract
Background and purpose
Iron deficiency (ID) impacts ∼50% of heart failure (HF) patients [1] and is a risk factor and strong predictor for death and mortality with or without anaemia [2]. Oral iron appears to be ineffective whilst intravenous iron (IV-iron) has proven to be efficacious however data is primarily from a Caucasian population [3] despite ID being more prevalent amongst Asians. The I4RON-HF study assesses efficacy of high-dose IV-iron versus oral iron in stable outpatients and inpatients amongst an Asian population recovering from episodes of decompensated HF.
Methods
This is a single-centre randomized controlled study, where patients who had symptomatic heart failure (Ejection Fraction <50% and New York Heart Association class 2–3) were randomized into two groups. The intervention arm received anywhere from 500mg to 1500mg of IV Iron Isomaltoside as a single infusion, whereas the control arm received routine iron supplements.
The primary study endpoint was the percentage of patients achieving iron repletion at 4,8 and 12 months after enrolment. Secondary endpoints included clinical parameters (6-minute walk test, NYHA status and 2D-Echocardiogram), and biochemical parameters (Serum NTproBNP, Cardiac Troponin-T and hemogloblin) at 4,8 and 12 months.
Results
A total of 65 patients were enrolled (male 55%), 33 in the interventional arm and 32 in the control arm. There were no patients lost to follow up. 96.9% of patients in the IV Iron arm achieved the primary endpoint at 4 months, compared to 68.7% in the control group. These findings we consistent at 8 months (90.9% vs 65.6%) and 12 months (90.9% vs 56.2%). Looking at the secondary endpoints, the IV Iron cohort recorded a 11.14% increase in Hemogloblin levels versus the control arm which recorded a reduction of 16.23%. There was also lower NTproBNP levels in the IV iron group (81.6% reduction) versus the control group (66.3% reduction). Clinically, the patients who received IV iron had a 42.98% increase in their 6-minute walk test from baseline, compared to an increase of 8.61% in the control arm. There were no significant echocardiographic changes.
Conclusion
These findings in our single-centre study support the efficacy of IV iron over oral supplements in the treatment of iron deficiency amongst Asian heart failure patients. The secondary endpoints also indicate better clinical and biochemical outcomes when iron stores are successfully repleted. Lastly, this study demonstrates the feasibility and safety of outpatient administration of high-dose IV-iron. Results from large-scale clinical studies looking at hard endpoints (mortality, HF hospitalization) are expected to further advance understandings.

Abstract
Abstract
Background
The impact of malnutrition on outcomes in a contemporary ST-segment-elevation myocardial infarction (STEMI) population is unclear. We hypothesized that malnutrition severity amongst STEMI patients undergoing primary percutaneous coronary intervention (pPCI) is associated with worse long-term outcomes.
Purpose
The aim of this study was 2-fold: 1) to establish the prevalence of malnutrition among STEMI patients undergoing pPCI; 2) to determine the association of malnutrition severity on in-hospital and 1-year outcomes in STEMI patients receiving pPCI
Methods
We retrospectively identified 1,169 STEMI patients of age ≥65 years who had received pPCI (2013–2020). Patients who had presented with out-of-hospital cardiac arrest or those who received fibrinolytic therapy were excluded. The Controlling Nutritional Status (CONUT) score, based on serum albumin, total cholesterol and lymphocyte count, was used as a tool to assess the nutritional status of included patients. Malnourished patients were defined as those with a CONUT score of 5 to 12. To account for the impact of frailty, a frailty index (FI) was determined using the health deficit accumulation model (Table 1). The primary outcome was 1-year all-cause mortality. The secondary outcome was a composite of in-hospital heart failure, cardiogenic shock, re-infarction, major bleeding, stroke, and all-cause mortality. A multivariable model adjusting for baseline covariates, including frailty index score, was performed (Figure 1).
Results
Among 1,169 STEMI patients receiving pPCI, 315 (26.9%) were classified as malnourished. Malnourished patients were older (mean 77.4 vs. 76.0 years, p=0.009) and had a higher comorbidity burden. After multivariable adjustment, worsening malnutrition was associated with increased 1-year all-cause mortality (odds ratio [OR] = 1.29, p<0.001). Worsening malnutrition was also associated with a higher incidence of the in-hospital composite adverse outcome (OR = 1.12, p=0.003) and increased in-hospital all-cause mortality (OR=1.41, p<0.001).
Conclusion
Among STEMI patients receiving pPCI, 1 in 4 were malnourished. Malnutrition was associated with increased rate of in-hospital composite adverse outcome and worse long-term outcomes, even when accounting for frailty. Efforts to routinely identify malnourished STEMI patients and to implement best practices to reduce the risk of adverse events in this vulnerable population are warranted.

Abstract
The aim of this study was to examine genetic variations underlying the early neurodevelopmental outcome of developmental disabilities (DDs). The study cohort consisted of 191 children with DDs. Diagnosis was assessed at baseline and at the index age (72-84 months). Exome sequencing was conducted and putative risk variants were identified. According to the diagnostic improvement, children were categorized into the improvement group (n = 19) and the non-improvement group (n = 172). Compared to the non-improvement group, the improvement group had lower number of risk variants in known DD genes and haploinsufficient genes, and lower number of overall putative risk variants. Our results may serve as a preliminary basis for developing a model that informs clinical outcome by sequencing analysis.

Abstract
For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion.

Abstract
OBJECTIVE Studies on the early trajectories of developmental disability (DD) are limited. This study aimed to evaluate the diagnostic stability and developmental trajectories of autism spectrum disorder (ASD) and intellectual disability (ID), and to determine baseline clinical characteristics that affect future diagnosis. METHODS We analyzed 192 children who were referred for possible DD through retrospective chart review. Clinical diagnosis was assessed once at baseline, aged 2-4, and at follow-up, aged 4-6. The participants' developmental profiles were measured by Psychoeducational Profile-Revised (PEP-R), Vineland Social Maturity Scale (VSMS), Beery-Buktenica Developmental Test of Visual Motor Integration (VMI), and Childhood Autism Rating Scale (CARS). RESULTS On comparing the diagnostic change, 5% of children were no longer diagnosed as ASD, and 13% of children were no longer diagnosed as ID at follow-up. Trajectories of developmental profiles were compared between children with and without ID at follow-up, and significant time-by-group interaction were observed in PEP-R (p<0.001), VSMS (p<0.001), and VMI (p=0.003) scores, indicating that children without ID at follow-up showed significant improvement over time compared to children with ID. ASD diagnosis (p<0.001) and CARS score (p=0.007) at baseline were significantly associated with ASD at follow-up, while VSMS score (p=0.004) and VMI score (p=0.019) at baseline were significantly associated with ID at follow-up. CONCLUSION A subset of children lost their diagnosis at follow-up, and such diagnostic change was significantly more common in ID compared to ASD. Baseline autism symptomatology was related to ASD at follow-up, and baseline adaptive and visuo-motor function was related to ID at follow-up.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
BACKGROUND The aim of this study is to explore whether high school students' adherence to physical distancing was associated with health beliefs, social norms, and psychological factors during the coronavirus disease 2019 (COVID-19) pandemic. METHODS Overall, 300 high school students participated in this anonymous online survey conducted from October 18-24, 2021. The survey included rating scales such as attitude toward physical distancing during the pandemic, Stress and Anxiety to Viral Epidemics-6 items (SAVE-6), Patient Health Questionnaire-9 items, Satisfaction with Life Scale, and Connor Davidson Resilience Scale 2-items. RESULTS The results revealed that perceived susceptibility or severity (β = -0.13, P = 0.038), perceived benefit (β = 0.32, P < 0.001), descriptive social norms (β = 0.10, P = 0.041), social injunctive norms (β = 0.19, P < 0.001), and SAVE-6 (β = 0.24, P < 0.001) predicted students' adherence to physical distancing (adjusted R² = 0.42, F = 19.2, P < 0.001). Social injunctive norms and personal injunctive norms directly influenced adherence to physical distancing. Viral anxiety, measured by SAVE-6, mediated the association between social injunctive norms and adherence to physical distancing, and perceived benefits mediated the relationship between personal injunctive norms and adherence to physical distancing. The influence of perceived susceptibility or severity on adherence to physical distancing was entirely mediated by perceived benefits or viral anxiety. CONCLUSION Explaining the rationale or benefits of physical distancing may be important in increasing adherence to physical distancing among high school students.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
OBJECTIVE This study aimed to explore whether screen time and the screen type impacted various health aspects of children, including physical activity (PA), sleep quality, and eating habits. Additionally, we investigated whether children's eating behavior while using electronic devices affects their physical and mental health. METHODS We conducted an online survey asking for screen use (duration, type, and purpose), PA, eating habits, sleep problems, and level of depression. The participants were children between the ages of 3 and 7 years, and the survey was answered by the participants' parents from March 3 to March 20, 2021. RESULTS A screen time of ≥2 h in children was associated with various clinical characteristics, such as body mass index (BMI), sleep problems, depression, decreased PA, and unusual eating habits. Children's food eating behavior while using electronic devices was predicted by a total screen time ≥2 h, smartphone screen time ≥2 h, sleep problems, owning electronic devices, and eating unhealthy food. CONCLUSION There was an interplay among children's PAs, eating behaviors, depression, sleep problems, and screen time in this pandemic era. Therefore, guiding children on the correct use of electronic devices and helping them eat healthy are paramount during this COVID-19 pandemic.

Abstract
BACKGROUND We evaluated the efficacy of adjuvant durvalumab after neoadjuvant concurrent chemoradiotherapy (CCRT) in patients with esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS This randomized, double-blind, phase II study included patients with ESCC who underwent curative surgery after neoadjuvant CCRT. Patients were randomized to receive either durvalumab (20 mg/kg/i.v. every 4 weeks for 12 months) or placebo in a 1:1 ratio and were stratified by age and pathologic tumor stage. The primary endpoint was disease-free survival (DFS). RESULTS Between March 2016 and June 2018, 86 patients were randomized to the durvalumab (n = 45) or placebo (n = 41) arm. The median follow-up duration was 38.7 months. There was no difference in DFS [hazard ratio (HR) 1.18, 95% confidence interval (CI) 0.62-2.27, P = 0.61] or overall survival (HR 1.08, 95% CI 0.52-2.24, P = 0.85) between the two arms. Subgroup analysis was performed for patients for whom the post-CCRT programmed death-ligand 1 (PD-L1) expression profile could be assessed (n = 54). In the PD-L1-positive group, based on tumor proportion score ≥1%, durvalumab was associated with longer overall survival compared with the placebo (36-month survival rate: 94% versus 64%; HR 0.42, 95% CI 0.10-1.76), while in the PD-L1-negative group, it was associated with shorter overall survival (42% versus 55%; HR 1.53, 95% CI 0.48-4.83), showing the tendency of interaction between post-CCRT PD-L1 status and adjuvant durvalumab therapy for overall survival (interaction P = 0.18). CONCLUSIONS We failed to demonstrate that adjuvant durvalumab improved survival after neoadjuvant CCRT in patients with ESCC. However, post-CCRT PD-L1 expression could predict the survival of patients who receive adjuvant durvalumab after neoadjuvant CCRT, which needs to be validated.

[PMID: 35733798 PMCID: PMC9207240 DOI: 10.3389/fpsyt.2022.839656] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Accepted: 04/21/2022] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION The aims of this study were to examine the mediation effect of viral anxiety of healthcare workers on the influence of their intolerance of uncertainty on the adherence to physical distancing during the COVID-19 pandemic. METHODS An online survey was conducted among 329 healthcare workers (female: 81.4%, nursing professionals: 59.0%, and shift workers: 22.3%) on November 29, 2021. Participants responded to questionnaires on adherence to physical distancing, health beliefs, and perceived social norms, and rating scales of the Stress and Anxiety to Viral Epidemics-6 items (SAVE-6), Patient Health Questionnaire-9 items (PHQ-9), and the Intolerance of Uncertainty-12 items (IUS-12) scale. RESULTS Adherence to physical distancing of healthcare workers was predicted by perceived benefits of physical distancing (β = 0.13, p = 0.01), personal injunctive norms (β = 0.32, p < 0.001), SAVE-6 score (β = 0.13, p = 0.02), and IUS-12 score (β = 0.10, p = 0.045) (adjusted R2 = 0.21, F = 22.3, p < 0.001). Viral anxiety mediated the association between intolerance of uncertainty and adherence to physical distancing but not the influence of perceived benefits and personal injunctive norms on adherence to physical distancing. CONCLUSION We observed that viral anxiety of healthcare workers mediated the association between intolerance of uncertainty and adherence to physical distancing. During this pandemic, exploring adherence to physical distancing and its predicting factors will be helpful for the safety of healthcare workers and the patients for whom they care.

Psychometric Properties of the Stress and Anxiety to Viral Epidemics-6 Items (SAVE-6) Scale for High School Students During the COVID-19 Pandemic. Front Psychiatry 2022; 13:815339. [PMID: 35599771 PMCID: PMC9116484 DOI: 10.3389/fpsyt.2022.815339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Accepted: 03/16/2022] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVES Owing to the COVID-19 pandemic, high school students have experienced a sudden change of school environment, which may result in difficulties related to mental health. The aim of this study is to estimate the reliability and validity of the Stress and Anxiety to Viral Epidemics-6 Items (SAVE-6) scale among high school students. METHODS A cross-sectional online survey was conducted among 300 high school students. The following scales were administered: the SAVE-6, Generalized Anxiety Disorder-7 Items (GAD-7), and Patient Health Questionnaire-9 Items (PHQ-9). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted, and the psychometric properties of the SAVE-6 were assessed. RESULTS The results of the CFA indicated good model fit for the SAVE-6 scale among high school students (χ2/df = 0.485, CFI = 1.000, TLI = 1.010, RMSEA < 0.001, and SRMR = 0.029). In addition, the SAVE-6 scale demonstrated good reliability (Cronbach's alpha = 0.844, McDonald's Omega = 0.848, and split-half reliability = 0.883). The appropriate cut-off score for the SAVE-6 scale was estimated as ≥15, which corresponds to a mild level of anxiety as assessed by the GAD-7 (≥5). CONCLUSION The SAVE-6 scale was found to be reliable and valid, and can be used as a tool to assess the stress and anxiety of high school students during the COVID-19 pandemic.

Abstract
Background and Objective Our aim is to investigate the impact of COVID-19 on screen time among Lebanese high school students (grades 9–12).Methods An anonymous online questionnaire was distributed among 510 school students from different governorates in Lebanon; this included questions regarding screen time, food habits, and physical activity. Psychological symptoms were assessed using the Generalized Anxiety Disorder-7 items and Patient Health Questionnaire-9 items. Effects of screen time on sleep was evaluated using the Insomnia Severity Index and Bedtime Procrastination Scale.Results Female students reported higher depression (p = 0.018) and anxiety (p = 0.023) than male students; however, there was no difference in their sleep. Insomnia, depression, and anxiety were highest among phone users. A screen time of more than 7 hours per day was significantly associated with higher depression (67.9%), anxiety (61.6%), insomnia (82.1%), and bedtime procrastination. It also indicated a shift toward a less healthy diet and light exercise.Conclusions Seven hours of screen was found to develop depression and anxiety, exercising less, eating a less healthy diet, and experiencing disturbed sleep among school adolescents.

Molecular epidemiology and antimicrobial resistance profiles of Salmonella isolates from dairy heifer calves and adult lactating cows in a Mediterranean pasture-based system of Australia. J Dairy Sci 2021; 105:1493-1503. [PMID: 34955273 DOI: 10.3168/jds.2021-21084] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 10/23/2021] [Indexed: 12/31/2022]
Abstract
Dairy cows can be reservoirs of foodborne pathogens such as Salmonella that pose serious public health risks to humans. The study was designed to examine the molecular epidemiology and antimicrobial resistance profiles of Salmonella isolates from dairy heifer calves and adult lactating cows in the pasture-based system of Australia. A total of 838 animals (328 heifer calves and 510 lactating cows) from 22 farms were sampled. Overall, 54 Salmonella isolates were recovered (calves 28/328 and cows 26/510). A herd-level Salmonella prevalence of 50% (95% confidence interval: 31%-69%) was recorded. Within-herd prevalence for Salmonella ranged between 4%-29% and 4%-45% among the heifer calves and adult lactating cows, respectively. Three different serovars were identified with Salmonella Infantis being the most common serovar (n = 33, 61%) followed by Salmonella Kiambu (n = 20, 37.0%) and one isolate of Salmonella Cerro (2%). The highest antimicrobial resistance prevalence of Salmonella isolates was found against streptomycin (n = 31, 57%), followed by cefoxitin (n = 12, 22%), ceftriaxone (n = 2, 4%), and chloramphenicol (n = 1, 2%). Multiple class resistance was observed on 4 isolates against cefoxitin, chloramphenicol, and streptomycin. Multilocus sequence types ST32 (61%), ST309 (37%), and ST367 (2%) were strongly linked to the serovars Salmonella Infantis, Salmonella Kiambu, and Salmonella Cerro, respectively. Whole genome sequencing of Salmonella isolates detected only 2 resistance genes: aac(6') gene that confers resistance against aminoglycosides among 40.7% of the isolates, and a single isolate positive for the blaDHA-16 gene. Two distinct clusters among the serovars were observed suggesting 2 independent sources of spread. Despite the low prevalence of antimicrobial resistance among Salmonella from the dairy farms, our findings contribute to the regional and national understanding of antimicrobial resistance in dairy herds in Australia. There is need for continued antimicrobial resistance stewardship and surveillance programs to ensure the production of high-quality food products and the long-term protection of both animal and human health.

Abstract
Abstract
Background
The long-term prognosis of survival in patients with out-of-hospital cardiac arrest (OHCA) with coronary artery disease (CAD) remains poor.
Methods
There were 2391 out-of-hospital cardiac arrest (OHCA) patients transferred to 2 hospitals. We included 405 cardiovascular arrest patients, who got return of spontaneous circulation (ROSC) from January 2015 to December 2018. Among them, 204 patients had CAD that caused OHCA (39%: multi-vessel disease, 19%: chronic total occlusion (CTO), 13%: vasospastic angina (VSA)). To predict mortality, we investigated patients' characteristics, pre-hospital information and findings of CAG.
Results
At 1-year later, 104 patients (51%) survived. Younger age (P<0.001), VF survivor (P<0.001), pre-hospital ROSC (P<0.001), bystander CPR (P=0.013), without ECMO (P<0.001), lower lactate level on admission (P<0.001), and higher geriatric nutritional risk index score (P<0.001) were associated with low 1-year mortality, while with ST-segment elevation (P=0.778), BMI level (P=0.344), and sex (0.401) were not. And in the findings of CAG, the past history of CAD (P=0.049), the higher number of coronary vessel disease (P=0.003) such as multi-vessel disease (P=0.022), higher SYNAX score (P=0.016), and larger infarct size (max CK level; P=0.013, max CK-MB level; P<0.001) were associated with high 1-year mortality. On the other hand, acute coronary syndrome (P=0.300), any coronary lesion (RCA (P=0.447), LAD (P=0.089), LCX (P=0.096), or LMT (P=0.842)), and with CTO lesion (P=0.140) were not associated. Zero-vessel disease (VSA, P=0.001) had lower mortality among the CAD patients. In the multivariate Cox proportional hazards model, age (hazards ratio; HR: 1.03, 95%confidence interval (CI) 1.00–1.06, P<0.001) and bystander CPR (HR: 0.36, 95% CI 0.20–0.65, P<0.001) were the independent predictors of mortality.
Conclusions
Younger age and pre-hospital support after OHCA with CAD were the predictors of low mortality. Pre-hospital information, systemic condition on arrival, or anatomical coronary complexity were important to predict low mortality.

Abstract
Abstract
Background
Percutaneous coronary intervention (PCI) for calcified coronary artery remains challenging in the drug-eluting stent (DES) era. The effectiveness of drug-coated balloons (DCBs) and orbital atherectomy system (OAS) is unknown.
Methods
In this retrospective, single-center study, we compared the use of DCBs with second- and third-generation DESs following orbital atherectomy (OA) for calcified de novo coronary lesions. All patients underwent PCI with intravascular imaging. The primary endpoint was major cardiac event, that was a composite of cardiac death, death for unknown cause, non-fatal myocardial infarction, or target lesion revascularization at 1 year.
Results
Between June 2018 and December 2019, 107 patients with coronary lesions were enrolled in this study and divided into two groups: 23 patients in DCB group and 84 patients in DES group. The post-procedure segment percentage diameter stenosis was 23.1% (interquartile range [IQR], 17.7 to 32.5) with DCB versus 14.4% (IQR, 10.0 to 21.2) with DES (P<0.001). Overall adverse event rate for PCI procedure was low: one dissection with DES group, no persistent slow/no-flow, and no perforation with both group. The primary endpoint was not significantly different between 2 groups [DES: 6.0% (5/84), DCB: 0.0% (0/23), log-rank P=0.24].
Conclusions
In calcified coronary artery disease, using DCB following OA is as safe and effective as using DES following OA with respect to 1-year clinical outcomes.

Abstract
Abstract
Background
Venous thromboembolism (VTE) is the third most common cardiovascular condition in adult patients. Older patients are at an increased risk of VTE. However, they have been underrepresented in clinical trials and evidence on the safety and effectiveness of anticoagulants in older VTE patients, especially very elderly patients (≥80 years), is sparse.
Purpose
To evaluate the risk of recurrent VTE, major bleeding (MB), and clinically relevant non-major (CRNM) bleeding among older VTE patients initiating apixaban or warfarin according to two age sub-groups: 65–79 and ≥80 years.
Methods
Older VTE patients (aged ≥65 years) who initiated apixaban or warfarin were identified from the CMS Medicare database (September 2014–December 2017). To balance the characteristics between apixaban and warfarin patients, stabilized inverse probability treatment weighting (IPTW) was conducted. Post IPTW, a subgroup interaction analysis was conducted to evaluate if there was any difference in treatment effects between the two age subgroups (65–79 vs. ≥80) on recurrent VTE, MB, and CRNM bleeding. Cox proportional hazard models were used to conduct the interaction analysis, and the statistical significance of the interaction was set to p-value <0.10.
Results
A total of 22,135 apixaban and 45,840 warfarin patients with VTE aged ≥65 years were eligible for analysis. Post IPTW, patient characteristics were balanced between the apixaban and warfarin treatment cohorts. Apixaban patients had significantly lower risk of recurrent VTE, MB, and CRNM bleeding compared to warfarin patients (Figure). 42,551 (62.6%) were aged 65–79 years and 25,424 (37.4%) were aged ≥80 years. Among apixaban or warfarin patients, those aged 65–79 years had lower Charlson comorbidity index scores (mean 2.7 vs 3.2) and were less likely to have a diagnosis of anemia (34.7–34.9% vs 42.3–42.5%), cerebrovascular disease (14.7–15.7% vs 20.3–20.5%), or dementia (5.0–6.9% vs 20.4–24.6%) compared to patients aged ≥80 years. Across both age subgroups, incidence rates of recurrent VTE, MB and CRNM bleeding were lower for apixaban vs. warfarin. No significant interaction was observed between the treatment and age on recurrent VTE and MB (Figure). There was a significant interaction between treatment and age on CRNM bleeding. Apixaban trended towards a lower risk of CRNM bleeding across both age groups but the treatment effect on CRNM bleeding was larger for patients aged 65–79 years.
Conclusion
The treatment effects of apixaban vs. warfarin on recurrent VTE and MB were consistently observed across both older age groups in this analysis. More studies are needed to evaluate management of VTE in an older and especially the very elderly population.

Abstract
Abstract
Background
Race has been identified as a risk factor for venous thromboembolism (VTE), with Black individuals having a higher risk of VTE compared to Caucasians. Black patients have been underrepresented in clinical trials evaluating anticoagulants for VTE. There has been limited evidence about the effects of anticoagulants for Black patients with VTE in routine clinical practice.
Purpose
To evaluate the risk of recurrent VTE, major bleeding (MB), and clinically relevant non-major (CRNM) bleeding among VTE patients initiating apixaban or warfarin stratified by race.
Methods
Older VTE patients (≥65 years) who initiated apixaban or warfarin were selected from the CMS Medicare database (September 2014–December 2017). Stabilized inverse probability treatment weighting (IPTW) was used to balance the differences between apixaban and warfarin cohorts. After IPTW, subgroup interaction analysis was conducted to evaluate if treatment effects were different between Black and White patients in the Medicare population. Due to small sample size, other races were not included in the interaction analysis. Cox proportional hazard models were used to evaluate if there was significant interaction (p<0.10) between treatment and race on recurrent VTE, MB, or CRNM bleeding.
Results
A total of 22,135 apixaban and 45,840 warfarin patients with VTE were included in the analysis. Post-IPTW, patient characteristics were balanced between apixaban and warfarin treatment cohorts. Apixaban patients had significantly lower risk of recurrent VTE, MB, and CRNM bleeding compared to warfarin patients (Figure). When stratified by race, 57,008 (83.9%) were White, 7,832 (11.5%) Black, and 3,135 (4.6%) other races. For both treatment cohorts, age was similar between Black (77.0–77.2 years) and White (77.4–77.5 years) patients. However, Black patients were more likely to have an inpatient VTE event (77.3–77.8% vs. 63.1–63.3%), a provoked VTE event (78.6–79.5% vs 69.4–69.6%), and a higher comorbidity index score (mean 4.1 vs. 2.7) compared to White patients with VTE. The incidence rates per 100 person-years of recurrent VTE (2.0–3.3 vs 1.4–2.2) and MB (7.4–10.1 vs 3.5–5.3) were also numerically higher for Black patients compared to White patients. Across both race groups, apixaban patients had a lower incidence rate of recurrent VTE, MB and CRNM bleeding compared to warfarin patients. No significant interaction was observed between treatment and race for recurrent VTE, MB, or CRNM bleeding (Figure). The findings within each race group were consistent with those of the overall VTE population.
Conclusion
Among older VTE patients, disparities were observed in VTE characteristics and clinical outcomes between Black and White patients. Across both race groups, apixaban had lower risk of recurrent VTE, MB, and CRNM bleeding compared to warfarin patients. Further studies are needed to identify optimal management strategies for Black patients with VTE.

Abstract
Abstract
Background
Venous thromboembolism (VTE) is a serious disease in the United States affecting approximately 1 in 1000 patients each year. Patients with chronic liver disease (CLD) are at an increased risk of VTE and major bleeding (MB). Currently, insufficient clinical and real-world evidence exists on the efficacy/effectiveness and safety of apixaban or warfarin in VTE patients with CLD.
Purpose
To evaluate the risk of recurrent VTE, MB, and clinically relevant non-major (CRNM) bleeding among VTE patients initiating apixaban or warfarin stratified by CLD status.
Methods
VTE patients ≥18 years of age (≥65 years for Medicare) initiating apixaban or warfarin were identified from CMS Medicare and four commercial claims databases. To balance the characteristics between apixaban and warfarin patients, stabilized inverse probability treatment weighting (IPTW) was conducted. Post-IPTW, subgroup interaction analysis was conducted to evaluate whether treatment effects of apixaban vs. warfarin were consistent across patients with and without a diagnosis of CLD. Cox proportional hazard models were used to evaluate the interaction of the treatment (apixaban vs. warfarin) and CLD on recurrent VTE, MB, and CRNM bleeding. The statistical significance of the interaction was set to p-value <0.10.
Results
A total of 60,786 apixaban and 94,333 warfarin patients with VTE were eligible for analysis. Post-IPTW, all patient characteristics were balanced between the apixaban and warfarin treatment cohorts. Apixaban treated patients had significantly lower risk of recurrent VTE, MB, and CRNM bleeding compared to warfarin patients (Figure). In the IPTW weighted population, 4,766 (7.8%) apixaban patients and 6,320 (6.7%) warfarin patients had a diagnosis of CLD. For the apixaban or warfarin patients, those with a diagnosis of CLD were generally younger (mean 64.0–65.2 vs 66.9 years), had higher Charlson comorbidity index scores (mean 3.8–3.9 vs 2.1) and were more likely to have an inpatient VTE event (67.8–69.5% vs 53.0–53.2%) or provoked VTE events (66.2–67.8% vs 55.4–55.5%) compared to patients without a diagnosis of CLD. The incidence rate of recurrent VTE, MB, and CRNM bleeding was higher among VTE patients with CLD than without CLD and was also higher for patients treated with warfarin compared to those treated with apixaban regardless of CLD status (Figure). There were no significant interactions observed between treatment and CLD status for recurrent VTE, MB or CRNM (Figure).
Conclusion
Treatment with apixaban had a lower risk of recurrent VTE, MB, and CRNM bleeding compared to treatment with warfarin. The benefits of apixaban were consistently observed among subgroups of VTE patients with and without CLD. Additional studies are needed to evaluate VTE patients with CLD.

Abstract
OBJECTIVES Sleep difficulties are associated with various behavioral problems and cognitive development, but the association has not been thoroughly evaluated in preschoolers with and without developmental disability (DD). The aim of this study was to compare the behavioral and cognitive characteristics of poor and good sleepers with and without DD in a community-based sample of preschool children. METHODS We recruited 196 children aged 34-77 months from community-based daycare centers, kindergartens, and special education centers. Children were classified as poor sleepers with DD (n = 23), poor sleepers without DD (n = 23), good sleepers with DD (n = 64), and good sleepers without DD (n = 94). Poor sleepers were defined based on Children's Sleep Habits Questionnaire Total Sleep Disturbance Score (CSHQ TSDS) cutoff of >52. RESULTS When compared to good sleepers with DD, poor sleepers with DD scored significantly higher on the Attention Problems (p = 0.005) and Aggressive Behaviors (p = 0.001) subscales of the CBCL, indicating greater difficulty. Caregivers of the poor sleepers with DD reported more depressive symptoms (p = 0.028) and more stress related to the child (p = 0.002) and the parent (p = 0.045) than caregivers of the good sleepers with DD. On the other hand, when compared to good sleepers without DD, poor sleepers without DD scored significantly higher only on the Anxious/Depressed subscale (p = 0.045) of the CBCL. Cognitive development and adaptive functioning were not significantly different between poor and good sleepers with and without DD. Among the subscales of the CSHQ, the Sleep Onset Delay showed strongest correlation with behavioral measures of the children and distress of the caregivers. CONCLUSION Externalizing problems such as aggressive behaviors, rather than cognitive development, are associated with sleep difficulties in preschool children with DD.

Abstract
Study question Under deadly pandemic conditions involving the novel SARS-CoV–2 corona virus, could biopsied blastocysts be safely cryopreserved, stored and utilized for subsequent warming cycles? Summary answer Blastocysts were securely stored, effectively warmed and safely transferred to yield normal pregnancy outcomes under uncertain laboratory conditions subject to unprecedented policy changes. What is known already By April 2020, every IVF lab worldwide was implementing deep cleaning/disinfecting procedures in their laboratory and patient-contact areas, thorough hand-washing policies and mandatory PPE to reduce the chance of contact transmission and spread of the potentially deadly SARS-CoV–2 coronavirus. Furthermore, we know that safeguards like oil overlay culture dishes and pipetting dilution factors provide insurance against possible contamination. However, knowing that the trophectoderm of blastocysts possessed the ACE–2 binding receptor, potential concern existed regarding the continuation of laser zona opening and biopsy procedures that could possibly expose cryopreserved embryos to the coronavirus in liquid nitrogen storage (vapor or liquid). Study design, size, duration Between March 8 and December 22, 2020, 508 patients performed FET cycles involving the use of single (n = 490) or dual (n = 18) euploid microSecure vitrified blastocysts. In this retrospective analysis, we compared clinical pregnancy outcomes to a 5 year dataset (2015–2019) encompassing 2768 single and 272 dual embryo transfer FET cycles. All blastocysts were vitrified using a closed microSecure system and Innovative Cryoenterprise (ICE; NJ, USA) non-DMSO, glycerol-EG solutions. Differences were assessed by Chi-square analysis (p < 0.05). Participants/materials, setting, methods Deep cleaning was performed with Simple Green Pro3+ Virucide in non-lab areas (e.g., ET rooms, waiting room) and 6% H2O2 & OoSafe solutions to disinfect lab surfaces and equipment. Group embryo cultures were performed in MCO–5M humidified incubators under low oxygen tri-gas conditions with varying CO2 levels (5.3–6.0%; pH = 7.3–7.35) using 25µl droplets of LifeGlobal medium+7.5%LGPS+1%sodium hyaluronate, before changing to 10µl droplet/GPS dishes post-biopsy. FET cycles involved 4-step sucrose dilutions and transvaginal ultrasound-guided embryo transfers. Main results and the role of chance While ICSI fertilization rates were unchanged in 2020 (79.4% 2PN vs 77.3%), blastocyst utilization rates tended to be slightly lower than past years (56.4% vs 59.9%) but within an acceptable range. Of 529 blastocysts warmed, 527 (99.7%) survived completely for transfer, being comparable to the 99.4% experienced over 5 years. Furthermore, there was no differences detected in single embryo transfer pregnancy outcomes. The implantation and ongoing clinical pregnancy/live birth rates were 69% and 66.53% compared to 70.4% and 65.1%, respectively. Under pandemic conditions we did not observe an increase in biochemical pregnancies (10.3%) nor spontaneous miscarriage rates (7.8%). Although it is possible that our rigorous disinfection practices could have attributed to lower blastocyst production, the viability of those embryos was not compromised. Importantly, we were able to feel comfortable performing micromanipulation and cryopreservation procedures throughout the year knowing that we were effectively eliminating possible vertical transmission of coronavirus to an exposed trophectoderm layer in cryostorage by applying mircoSecure vitrification. Post-FET clinical check-ups revealed no patient reporting any fever or other Covid–19 symptoms in the weeks following their transfers. We are fortunate to say that our Lab staff, physicians and patients have remained healthy throughout 2020. Limitations, reasons for caution Blastocyst survival and viability are independent of possible viral exposure. Previously, the risk of disease transmission via liquid nitrogen or vapor exposure was considered highly unlikely (Pomeroy et al., 2010), but that was at a time when embryos were primarily zona-enclosed. Today’s ART standards have us re-evaluating safer approaches. Wider implications of the findings: We have effectively mitigated avoiding performing zona opening procedures by employing our standard practice of aseptic, closed vitrification. In combination with standard preventative measures (PPE, hand hygiene, distance awareness) and routine deep cleaning practices, we sustained a contamination-free environment and healthy patients, capable of sustaining high levels of pregnancy success.

Abstract
Abstract
Introduction
Diagnostic haematuria services have been reduced due to the COVID-19 pandemic, compromising patient care, and necessitating a more pragmatic pathway.
Method
The IDENTIFY study was an international, prospective, multicentre cohort study of over 11,000 patients referred to secondary care for investigation of haematuria. Using this data, we developed strategies using combinations of imaging and cytology as triage tests to maximise cancer detection within a pragmatic pathway.
Results
8112 patients (74·4%) received an ultrasound or a CT urogram, with or without cytology. 5737 (70·7%) patients had visible haematuria (VH) and 2375 (29·3%) had non-visible haematuria (NVH). Diagnostic test performance was used to determine optimal age cut-offs for four proposed strategies. We recommended proceeding directly to transurethral resection of bladder tumour for patients of any age with positive triage tests for cancer. Patients with negative triage tests under 35-years-old with VH, or under 50-years-old with NVH can safely be discharged without undergoing flexible cystoscopy. The remaining patients may undergo flexible cystoscopy, with a greater priority for older patients to capture high risk bladder cancer.
Conclusions
We suggest diagnostic strategies in patients with haematuria, which focus on detection of bladder cancer, whilst reducing the burden to healthcare services in a resource-limited setting.

Abstract
Abstract
To evaluate the valves used in the nuclear power plants are working properly under the required conditions, the performance and capacity test should be performed. In the test system, the accumulator was employed to control the large amount of high pressure and high temperature steam generated in the boiler precisely. In the accumulating process, the steam is often condensed. In order to prevent condensation, it is needed to install heaters and preheat the accumulator. However, if the size of the accumulator becomes large, the installation of the heater may not be easy. Therefore, when the test is conducted, the system was preheated by the latent heat generated from the phase change. Insufficient thermal insulation may cause temperature differences and it can cause mechanical problems in the accumulator structure. If insulation is sufficient, the temperature difference is indicated by the height. As the cooled condensate moves downwards, the condensate is discharged by the drain valve control and the temperature difference of the structure can be disappeared. The results of this paper can be applied to the conceptualization of equipment that uses latent heat and for the design of high-precision steam experimental devices or the design of high-capacity steam utilization systems.

The impact of pre-eclampsia definitions on the identification of adverse outcome risk in hypertensive pregnancy - analyses from the CHIPS trial (Control of Hypertension in Pregnancy Study). BJOG 2021; 128:1373-1382.

Abstract
OBJECTIVE To examine the association between pre-eclampsia definition and pregnancy outcome. DESIGN Secondary analysis of Control of Hypertension in Pregnancy Study (CHIPS) trial data. SETTING International multicentre randomised controlled trial (RCT). POPULATION In all, 987 women with non-severe non-proteinuric pregnancy hypertension. METHODS We evaluated the association between pre-eclampsia definitions and adverse pregnancy outcomes, stratified by hypertension type and blood pressure control. MAIN OUTCOME MEASURES Main CHIPS trial outcomes: primary (perinatal loss or high-level neonatal care for >48 hours), secondary (serious maternal complications), birthweight <10th centile, severe maternal hypertension, delivery at <34 or <37 weeks, and maternal hospitalisation before birth. RESULTS Of 979/987 women with informative data, 280 (28.6%) progressed to pre-eclampsia defined restrictively by new proteinuria, and 471 (48.1%) to pre-eclampsia defined broadly as proteinuria or one/more maternal symptoms, signs or abnormal laboratory tests. The broad (versus restrictive) definition had significantly higher sensitivities (range 62-79% versus 36-50%), lower specificities (range 53-65% versus 72-82%), and similar or higher diagnostic odds ratios and 'true-positive' to 'false-positive' ratios. Stratified analyses showed similar results. Addition of available fetoplacental manifestations (stillbirth or birthweight <10th centile) to the broad pre-eclampsia definition improved sensitivity (74-87%). CONCLUSIONS A broad (versus restrictive) pre-eclampsia definition better identifies women who develop adverse pregnancy outcomes. These findings should be replicated in a prospective study within routine healthcare to ensure that the anticipated increase in surveillance and intervention in a larger number of women with pre-eclampsia is associated with improved outcomes, reasonable costs and congruence with women's values. TWEETABLE ABSTRACT A broad (versus restrictive) pre-eclampsia definition better identifies the risk of adverse pregnancy outcomes.
