Abstract
The purpose of this study was to develop the Complex Trauma Screener (CTS), a brief screener (seven items) of the ICD-11 trauma disorders that can be used in "quick-paced" facilities. We examined the factor structure of the CTS in two separate samples: civilian college students (N = 823) and military veterans (N = 130) who reported exposure to at least one traumatic event. Confirmatory factor analyses (CFAs) supported two highly-correlated factors (post-traumatic stress disorder [PTSD] and Disturbances in Self-Organization [DSO]) that loaded on the ICD-11-consistent items. The model fit indices indicated good to excellent model fit in both samples, and the internal consistencies for the scales were borderline to good (α = 0.68-0.86). Supplementary analyses supported the gender invariance of the CFA model in the civilian student sample, as well as convergent (with another trauma inventory) and discriminant validity (with borderline disorder features, depression, and mania) of the CTS in both samples. The CTS is, to our knowledge, the shortest instrument designed to measure the ICD-11 trauma disorders and is ideal for "fast-paced" facilities that have significant assessment time restraints. The CTS is, therefore, is a psychometrically-validated instrument that can help mental health professionals efficiently screen adults for ICD-11 trauma disorders.

Abstract
BACKGROUND Undetected vision problems are common in school children, and a prevalence of up to 40% has previously been reported. Uncorrected vision and lack of optimal eye wear can have a significant impact on almost all aspects of everyday life, such as development and learning, academic performance, pain and discomfort, and quality of life. This study aimed to analyze the relationship between uncorrected vision problems, educational outcomes, and musculoskeletal pain symptoms. METHODS A total of 152 school children (15.1 ± 0.8 years, mean ± SD; 40% males) were included in the study. All participants were recruited from a free-of-charge school vision testing program in Kathmandu, Nepal. Academic grades were collected from the school records of the participants' nationwide final grade examinations. A questionnaire was used to record the use of digital devices, screen time, and associated symptoms, including musculoskeletal pain (Wong-Baker FACES Pain Rating Scales). RESULTS A total of 61 children (40%) had uncorrected vision, with a cycloplegic refraction of SER - 0.53 ± 0.52 (mean ± SD). Children with uncorrected vision had significantly more third division grades (26 vs. 9%, p = 0.004) and shoulder pain in general/during screen use (66 vs. 43/40%, p = 0.008/0.003; 2.1/1.9 vs. 1.1/1.0 mean pain score, p = 0.002/0.001) compared with children with normal vision. Sex based subanalyses showed that only girls with uncorrected vision had more third division grades (25 vs. 4%, p = 0.006), and only boys with uncorrected vision had more shoulder pain in general/during screen use (76 vs. 28/31%, p < 0.001; 2.2/2.4 vs. 0.7 mean pain score, p < 0.001), compared with children with normal vision. CONCLUSIONS The results of this study showed that even small refractive errors may impact educational outcomes and musculoskeletal pain in adolescents. Most of the participating children had low myopia, easily corrected with glasses. This suggests that regular eye examinations are important in school children, and there is a need for raised awareness among parents, and school- and healthcare personnel.

Abstract
The prevalence of patients with primary aldosteronism (PA) is about 5%-15% in hypertensive patients, and it is common cause of secondary hypertension in clinical practice. Two major causes of PA are noted, namely bilateral adrenal hyperplasia and aldosterone-producing adenoma, and the general diagnosis is based on three steps: (1) screening, (2) confirmatory testing, and (3) subtype differentiation (Figure 1). The recommendation for screening patients is at an increased risk of PA, here we focus on which patients should be screened for PA, not only according to well-established guidelines but for potential patients with PA. We recommend screening for 1) patients with resistant or persistent hypertension, 2) hypertensive patients with hypokalemia (spontaneous or drug-induced), 3) young hypertensive patients (age <40 years), and 4) all hypertensive patients with a history of PA in first-degree relatives. Moreover, we suggest screening for 1) hypertensive patients themselves or first-degree relatives with early target organ damage, such as stroke and other diseases, 2) all hypertensive patients with a concurrent adrenal incidentaloma, 3) hypertensive patients with obstructive sleep apnea, 4) hypertensive patients with atrial fibrillation unexplained by structural heart defects and/or other conditions resulting in the arrhythmia, 5) hypertensive patients with anxiety and other psychosomatic symptoms, and 6) hypertensive patients without other comorbidities to maintain cost-effectiveness.

Abstract
BACKGROUND Adolescence is a critical period for development, with many risk factors resulting in long-term health consequences, particularly regarding mental health. The purpose of this study was to examine the associations between problem technology use, life stress, and self-esteem in a representative sample of adolescents residing in Ontario, Canada. METHODS Self-reported data were obtained from a cross-sectional sample of 4,748 students (57.9% females) in grades 9 to 12 (mean age: 15.9 ± 1.3 years) who participated in the 2019 Ontario Student Drug Use and Health Survey. Problem technology use was measured using the 6-item Short Problem Internet Use Test, life stress was assessed using an item from the British Columbia Adolescent Health Survey and self-esteem was assessed using a global measure from the Rosenberg Self-Esteem Scale. Ordinal logistic regression models were adjusted for age, sex, ethnoracial background, subjective socioeconomic status, body mass index z-score, tobacco cigarette smoking, alcohol consumption and cannabis use. RESULTS We found that 18.3% of participants reported symptoms of moderate-to-high problem technology use, although symptoms were more common in females than males (22% vs. 14.7%, respectively). Moderate-to-high problem technology use was associated with 2.04 (95% CI: 1.77-2.35) times higher odds of reporting high life stress and 2.08 (95% CI: 1.76-2.45) times higher odds of reporting low self-esteem compared to all other response options. CONCLUSIONS Findings from this study show that problem technology use is strongly associated with higher life stress and lower self-esteem in adolescents. This study supports the importance of developing and implementing effective strategies that help to mitigate the adverse effects of problem technology use on adolescent mental health.

Abstract
Hydropower is a reliable source of renewable energy, and its future expansion is likely to be in the form of either smaller new stream development (NSD) projects or powering existing non-powered dams. Thresholds for entrainment risk to fish and the requirements for fish exclusion at hydropower facilities often differ depending on the species involved, the characteristics of the facility, and the goals of stakeholders, but little quantitative information is present within the literature regarding the specific costs of fish exclusion measures. Cost data associated with protection, mitigation, and enhancement (PM&E) measures related to positive barrier screening were identified using keyword searches of an existing environmental mitigation cost data set and manual extraction from regulatory licensing documents available in the Federal Energy Regulatory Commission (FERC) eLibrary. This approach yielded a total of 50 p.m.&E mitigation measures with estimated capital construction costs pertaining to positive barrier screens and represented <10% of the 171 total FERC project dockets available in the data set. These data were highly skewed toward conventional relicensing projects, as <7% were associated with NSD projects. Results indicate highly variable costs are associated with fish screening, with flow-normalized costs one to two orders of magnitude higher for screening with the highest exclusion capability (≤0.09 in. spacing) compared with coarser screening (1-2 in.). These data provide an initial baseline for estimating exclusion costs for hydropower development and may help developers consider options for more fish-friendly generation technologies, though gaps remain relating to a lack of data, particularly for NSD projects.

Abstract
BACKGROUND Concerns regarding the impact of screen-based sedentary behavior on health have been increasing. Therefore, the present study investigated the longitudinal relationship between multiple screen time and nutrient intake in children and adolescents. METHODS The present study was conducted utilizing 3 years longitudinal data. Study subjects were 740 Japanese children aged between 6 and 12 years at baseline and between 9 and 15 years in the follow-up. Screen-based sedentary behavior was assessed using screen time, including television (TV) viewing, personal computer (PC) use, and mobile phone (MP) use. The main outcomes were the intakes of nutrients. Mixed effect multivariate linear regression analyses were used to examine the longitudinal relationship between screen-based sedentary time and nutrient intake. Covariates included in the multivariable analysis consisted of sex, age, solitary eating, skipping breakfast, staying up late, and body weight status, as confounders, and physical inactivity, as mediator. RESULTS In boys, a longer total screen time longitudinally correlated with higher intake of energy and lower intakes of protein, dietary fiber, minerals, and vitamins. In girls, longer total screen time longitudinally associated with higher intake of sucrose and lower intakes of protein, minerals, and vitamins. In boys, a longer TV viewing time was associated with higher intake of sucrose and lower intakes of protein, minerals, and vitamins. In girls, a longer TV viewing time was associated with higher intake of carbohydrates and lower intakes of protein, fat, minerals, and vitamins. In boys, relationships were observed between a longer PC use time and higher intakes of energy as well as lower intakes of protein, minerals, and vitamins. Relationship was observed between longer PC use time and lower intakes of minerals in girls. An increased MP use time was associated with higher intakes of energy, and lower intakes of protein, sucrose, dietary fiber, minerals, and vitamins in boys. A longer MP use time was associated with higher intakes of fat, and salt as well as lower intakes of carbohydrates, protein, minerals, and vitamins in girls. CONCLUSIONS The present results revealed that longer screen-based sedentary behaviors were longitudinally associated with nutrient intake in children and adolescents. Future study is needed to elucidate these relationships.

Abstract
BACKGROUND Breast cancer perception is closely associated with the incidence of breast cancer among community-dwelling women. Consequently, it is crucial to enhance their breast cancer survival rate by assessing their cognitive status and implementing targeted interventions. This study aimed to translate the breast cancer perception scale into Chinese and validate its psychometric properties among community women. DESIGN A cross-sectional study method was introduced in this study. METHODS After obtaining the original author's authorization, the breast cancer perception scale was translated into Chinese using the Brislin back-translation method. Item analysis was employed to examine the discriminative power of the items, and the Delphi method was utilized to assess content validity. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to evaluate the scale's construct validity. Internal consistency and test-retest reliability were calculated to analyze reliability. RESULTS A total of 24 items were retained in the item analysis, and the content validity index of the translated scale was 0.964. In the EFA, six common factors were extracted, namely perceived knowledge, perceived treatment belief, perceived need for health checks, perceived stigma, perceived fear, and perceived risk, accounting for 74.911% of the cumulative variance. The CFA results were as follows: χ2/df = 1.301, GFI = 0.903, NFI = 0.913, TLI = 0.975, CFI = 0.978, IFI = 0.979, RMSEA = 0.037. The Cronbach's α coefficients, split-half reliability, and test-retest reliability of the translated scale were 0.895, 0.661, and 0.865, respectively. CONCLUSIONS The Chinese version of the breast cancer perception scale demonstrated suitable psychometric properties among community women. By evaluating results according to the scale, medical staff can enhance breast cancer prevention awareness and care for community-dwelling women and subsequently implement corresponding modifications.

Abstract
Objective/background The evidence on the association between screen use and sleep of adolescents is mainly based on studies about time watching television, with a few examining time using computers, videogames, and mobile devices. Our aim was to investigate the association between screen time for entertainment (watching TV, using computer, or playing games on tablets, smartphones, or videogame consoles) and sleep duration and self-reported sleep quality, among adolescents aged 15 years. Methods With data from the 2004 Pelotas Birth Cohort, sleep duration was assessed with questions extracted from the Munich Chronotype Questionnaire and quality was self-reported. Adjusted β coefficients and prevalence ratios (PR) with (95% confidence intervals) were obtained, respectively, by linear and Poisson regressions. Results 1,949 adolescents had information about screen time and sleep quality, and 1,851 about screen time and sleep duration. The median screen time was 4.5hs/24hs. The mean sleep duration was 7.6hs/24hs and the prevalence of bad sleep was 17.3% (15.7-19.0%). There was an inverse relationship between screen time and sleep duration. When compared with those with less than 2hs/24hs of screen time, adolescents with 6-8.8hs/24hs and ≥9hs experienced, respectively, 23.4 and 32.4 min reduction in sleep duration (β = -0.39; -0.62;-0.16 and β = -0.54; -0.77;-0.30). Adolescents with ≥9hs of screen time were 60% more likely to report bad sleep than those with less than 2hs/24hs (PR: 1.60; 1.10-2.32). Conclusions The median time spent using screens was longer than recommended. Screen use for ≥6hs/24hs was associated with a shorter sleep duration, and ≥9hs/24hs with poor sleep quality.

Abstract
Technology and screen media has its place in every home, yet the influences of the same are less known. This research aims to explore the vulnerabilities that prompt the mothers to use screen media for their children, prior to a diagnosis of autism for their child. It also aims to explore literature the influence of screen media on speech and language development in children. This study combined semi-structured interviews with 16 mothers of autistic children in Southern India and a scoping literature review that resulted in 24 articles. The literature refers to a positive influence when co-viewing with the child, and it predominantly highlights improvements in speech and not in language. The interviews revealed that screens were used as a means of support, a language and learning development tool, or as a calming technique. Thus, the study shows that the mothers resorted to screen use for their children more out of helplessness, and not as an informed choice. Mothers of autistic children clearly express their vulnerabilities and indicate feelings of being lost without advice, with regard to use of screen-time. This suggests a need for more research into how they can be supported.

Abstract
OBJECTIVE Dysphagia is a common and serious clinical symptom of amyotrophic lateral sclerosis (ALS). The study aimed to evaluate the diagnostic utility of four dysphagia screening tools in ALS, including the ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscale, water-swallowing test (WST), Eating Assessment Tool-10 (EAT-10) and Sydney Swallow Questionnaire (SSQ). METHODS A total of 68 individuals from First Hospital, Shanxi medical university, were recruited in the study. The ALSFRS-R, WST, EAT-10, SSQ and the gold standard video fluoroscopic swallowing study (VFSS) were performed. The Penetration Aspiration Scale (PAS) during VFSS was assessed to identify unsafe swallowing (PAS ≥ 3) and aspiration (PAS ≥ 6). Receiver operator characteristic curve (ROC) analyses were performed to evaluate the accuracy of the 4 tools. Youden index was used to determine the ideal cut-off value for each tool. RESULTS Of the patients, 20.59% (14/68) presented unsafety swallowing and 16.18% (11/68) had aspiration. The four tools could effectively identify patients with unsafe swallowing and aspiration. The EAT-10 had the maximum AUC (0.873 and 0.963, respectively) among the tools in the diagnosis of unsafe swallowing and aspiration. To detect unsafe swallowing and aspiration, an EAT-10 score of 6 (sensitivity: 78.6%, specificity: 87.0%) and an EAT-10 score of 8 (sensitivity: 90.9%, specificity: 91.2%), were the most appropriate cut-off points, respectively. CONCLUSIONS The ALSFRS-R bulbar subscale, WST, EAT-10, and SSQ could effectively identify unsafe swallowing and aspiration in patients with ALS. Of the four tools, the EAT-10 was relatively accurate, safe, and convenient. Further studies including more patients should be conducted to verify the conclusions.

Abstract
PURPOSE The purpose of this study was to develop and validate items for the Screen of Cancer. Survivorship - Occupational Therapy Services (SOCS-OTS), a patient-driven screening tool to be used by frontline workers and filled out by cancer survivors that can indicate a need for appropriate occupational therapy (OT) referral. METHODS Five rounds of a classical Delphi study were conducted to determine item inclusion. Expert panelists in rounds 1 and 2 consisted of adults LWBC who verified proposed items relevant to issues in activities of daily living (ADLs). Expert panelists in rounds 3-5 consisted of expert OTs who determined item relevance through consensus and item modification. RESULTS Forty-five adults living with and beyond cancer (LWBC) and 14 expert oncology occupational therapists and researchers participated in five rounds of surveys. A total of 20 items reached consensus at 80% with a "check all that apply" format. Items included address ADLs meaningful to adults LWBC. CONCLUSIONS The SOCS-OTS is an innovative content-valid screening tool designed to identify problems with ADLs relevant to OT referral. IMPLICATIONS FOR CANCER SURVIVORS The SOCS-OTS can empower cancer survivors and cancer care teams by indicating when daily activities are impacted enough to refer to OT services. This could ensure that cancer survivors receive the rehabilitation services they need.

Abstract
BACKGROUND Screen use before sleep is shown to be positively related to emotional problems. However, whether this relationship was mediated by circadian phenotypes (i.e., chronotype and social jetlag) remains unclear. METHODS Data from two independent adolescent surveys among 2685 and 1368 adolescents, respectively, were used. Adolescents reported screen use before sleep (yes/no and screen time), chronotype, social jetlag, and emotional problems using questionnaires. Serial mediation analyses were performed. RESULTS Adolescents who reported screen use before sleep showed later chronotype and greater social jetlag, which was further associated with a higher level of emotional problems. Such relationships held for screen use as a yes/no variable and screen time. The serial indirect effect of chronotype and social jetlag accounted for 6.2%-16.7% of the total effect of screen use before sleep on emotional problems. LIMITATIONS The use of a cross-sectional design did not allow the establishment of causal links between the variables. All data were self-reported by adolescents, and might be subject to report bias and recall bias. CONCLUSIONS These findings contributed to the existing literature by examining the mediating effect of chronotype and social jetlag in the relationship between screen use before sleep and emotional problems from a circadian rhythm perspective. Healthy media use habits and interventions targeting circadian characteristics may work towards promoting emotional health in adolescents.

Abstract
Digital eye strain (DES) or computer vision syndrome (CVS) is a phenomenon linked to ever increasing digital screen use globally, affecting a large number of individuals. Recognizing causative and alleviating factors of DES may help establish appropriate policies. We aimed to review factors that aggravate or alleviate DES symptoms in young, i.e. pre-presbyopic (<40 years old), digital device users. We searched PubMed, Scopus, EMBASE, Cochrane, Trip Database, and grey literature up to 1st July 2021. Among a plethora of studies with heterogeneous diagnostic criteria for DES, we only included those using a validated questionnaire for the diagnosis and evaluating associated factors in young subjects. Relevant data were extracted, risk of bias assessment of the included studies and GRADE evaluation of each outcome were performed. Ten studies were included (five interventional, five observational) involving 2365 participants. Evidence coming from studies with moderate risk of bias suggested that blue-blocking filters do not appear to prevent DES (2 studies, 130 participants), while use of screens for >4-5 h/day (2 studies, 461 participants) and poor ergonomic parameters during screen use (1 study, 200 participants) are associated with higher DES symptoms'score. GRADE evaluation for the outcomes of blue-blocking filters and duration of screen use showed low to moderate quality of evidence. It appears advisable to optimize ergonomic parameters and restrict screen use duration, for minimizing DES symptoms. Health professionals and policy makers may consider recommending such practices for digital screen users at work or leisure. There is no evidence for use of blue-blocking filters.

Abstract
Cancer drug development is hindered by high clinical attrition rates, which are blamed on weak predictive power by preclinical models and limited replicability of preclinical findings. However, the technically feasible level of replicability remains unknown. To fill this gap, we conducted an analysis of data from the NCI60 cancer cell line screen (2.8 million compound/cell line experiments), which is to our knowledge the largest depository of experiments that have been repeatedly performed over decades. The findings revealed profound intra-laboratory data variability, although all experiments were executed following highly standardised protocols that avoid all known confounders of data quality. All compound/ cell line combinations with > 100 independent biological replicates displayed maximum GI50 (50% growth inhibition) fold changes (highest/ lowest GI50) > 5% and 70.5% displayed maximum fold changes > 1000. The highest maximum fold change was 3.16 × 1010 (lowest GI50: 7.93 ×10-10 µM, highest GI50: 25.0 µM). FDA-approved drugs and experimental agents displayed similar variation. Variability remained high after outlier removal, when only considering experiments that tested drugs at the same concentration range, and when only considering NCI60-provided quality-controlled data. In conclusion, high variability is an intrinsic feature of anti-cancer drug testing, even among standardised experiments in a world-leading research environment. Awareness of this inherent variability will support realistic data interpretation and inspire research to improve data robustness. Further research will have to show whether the inclusion of a wider variety of model systems, such as animal and/ or patient-derived models, may improve data robustness.

Abstract
BACKGROUND The risk of low back pain (LBP) increases steeply during adolescence, and adolescents with LBP are more likely to have low back pain in their adult years. This study aimed to investigate the dose-response relationship between daily screen time and the risk of low back pain among children and adolescents. METHODS PubMed, the Cochrane Library, Embase, and Web of Science were searched to collect relevant studies on daily screen time and the risk of low back pain from the establishment of the database up to December 2022. Two investigators independently screened the literature, extracted data, and evaluated the risk of bias in the included studies. Stata16.0 was used to perform a dose-response meta-analysis and the methodological quality evaluation of the included studies. RESULTS The results of the meta-analysis showed that there is a positive correlation between daily computer time (OR = 1.32, 1.05-1.60), daily mobile phone time (OR = 1.32, 1.00-1.64), daily TV watching (OR = 1.07, 1.04-1.09) and the risk of low back pain, separately. The dose-response meta-analysis showed that there is a linear relationship between daily computer use and low back pain. The risk of low back pain increased by 8.2% for each 1-hour of daily computer use. CONCLUSIONS Screen time is related to the risk of low back pain, and there is a linear relationship between daily computer use and the risk of low back pain. A number of strategic measures should be taken to prevent adolescents from developing severe low back pain.

Abstract
BACKGROUND Family meals are an opportune context for initiating healthy eating habits in young children. However, using screens at family mealtimes may negate some of the associated nutritional and social benefits. In High Income countries, frequent mealtime screen use is common, particularly in families of low socioeconomic position (SEP). This study aimed to explore experiences and acceptability of mealtime screen use in families of low SEP with young children. METHODS Qualitative interviews with 25 mothers of low SEP were conducted via telephone or Zoom™ using Photo Interviewing and a semi-structured interview script. Transcripts were analysed thematically using a Constructivist paradigm. RESULTS Many parents reported an eagerness for reducing family mealtime screen use. Three major themes were identified in explaining the reasons behind levels of engagement in family mealtime screen use. These included parental self-efficacy, such as parental confidence in saying no to screens at mealtimes, physical resources such as having enough space in the home for a functioning dining table without view of a television, and temporal priorities such as prioritising screen use for managing children's difficult behaviour at mealtimes over long-term health considerations. CONCLUSIONS This study highlights that although family mealtime screen use is likely linked with a range of child behaviours and parenting practices that may negatively influence children's dietary intake and social engagement, parents often considered screens acceptable at mealtimes. Nonetheless, parents' desire to reduce family mealtime screen use provides an important opportunity to determine how best to support parents to achieve this.

Abstract
The bioactive sphingolipid ceramide impacts diverse cellular processes (e.g. apoptosis and cell proliferation) through its effects on membrane dynamics and intracellular signaling pathways. The dysregulation of ceramide metabolism has been implicated in cancer evasion of apoptosis and targeting ceramide metabolism has potential therapeutic benefits as a strategy to kill cancer cells and slow tumor growth. However, the mechanisms of cancer cell resistance to ceramide-mediated cell death are vastly intertwined and incompletely understood. To shed light on this mystery, we performed a genome-wide CRISPR-Cas9 screen to systematically identify regulators of cancer resistance to the soluble short chain ceramide, C6 ceramide (C6-Cer). Our results reveal a complex landscape of genetic modifiers of C6-Cer toxicity, including genes associated with ceramide and sphingolipid metabolism, vesicular trafficking, and membrane biology. Furthermore, we find that loss of the phospholipid flippase subunit TMEM30A impairs the plasma membrane trafficking of its binding partner, the P4-type ATPase ATP11B, and depletion of TMEM30A or ATP11B disrupts plasma membrane asymmetry and promotes resistance to C6-Cer toxicity. Together, our findings provide a resource of genetic modifiers of C6-Cer toxicity and reveal an unexpected role of plasma membrane asymmetry in C6-Cer induced cell death.

Abstract
PARP7 is an enzyme that catalyzes mono-ADP-ribosylation (MARylation), is a critical regulator of type I interferon signaling, and has emerged as an immune-oncology drug candidate. PARP7 is a labile protein that is regulated in a proteasome-dependent manner. Indeed, endogenous PARP7 levels are undetectable by western blot in most cells. Intriguingly, treatment of cells with orthosteric small molecule inhibitors of PARP7 can increase endogenous PARP7 protein to detectable levels. This characteristic of PARP7 inhibitors could potentially be exploited to assess target engagement-and thus cellular efficacy-of PARP7 inhibitors; however, no method exists to quantitatively monitor endogenous PARP7 levels in a high-throughput manner. In this protocol, we describe an assay using a split Nanoluciferase (NanoLuc) system for quantifying endogenous PARP7 protein levels and PARP7 inhibitor target engagement in cells in a 96-well plate format. We show that this assay can be used to quantify PARP7 protein levels under various cellular treatments and can assess cellular PARP7 inhibitor target engagement. We envision this split NanoLuc PARP7 assay can be used not only for evaluating the cellular efficacy of PARP7 inhibitors in a high-throughput manner but also for uncovering the mechanisms regulating PARP7 protein levels in cells.

Abstract
BACKGROUND Delirium is frequently unrecognized due to the absence of regular screening. In addition to validated bedside tools, the computer-assisted instrument based on clinical notes from electronic medical records may be useful. AIMS To assess the psychometric properties of a Chinese-chart-based keyword instrument for semiautomatically screening delirium using Natural language processing (NLP) based on clinical notes from electronic medical records. METHODS The patients were admitted to West China Hospital from January 2015 to December 2017. Grouping patients based on the medical notes, those with accessible physician documents but no nurse documents were classified as the physician & no-nurse (PNN) group, while those with accessible physician and nurse documents were classified as the physician & nurse (PN) group. The psychometric properties, test-retest reliability, internal consistency reliability (Cronbach's α), and criterion validity were calculated. Using receiver operating characteristic (ROC) analysis, the criterion validity of delirium was evaluated in comparison to the results of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. RESULTS A total of 779 patients were enrolled in the study. Their ages ranged from 65 to 103 years (82.5 ± 6.5), with men accounting for 71.9% of the total. A total of 312 patients had access to only physician documents in the physician & no-nurse (PNN) group, whereas 467 patients had access to both physician and nurse documents in the physician & nurse (PN) group. All 779 patients had a Cronbach's alpha of 0.728 in terms of reliability, with 100% test-retest reliability. The area under the ROC curve (AUC) values of the delirium screening instrument for criterion validity were 0.76 (all patients, n = 779), 0.72 (PNN, n = 312), and 0.79 (PN, n = 467), respectively. CONCLUSION A delirium screening instrument composed of Chinese keywords that can be easily and quickly obtained from electronic medical records was developed, which improved delirium detection in older people.

Abstract
OBJECTIVES Cognitive impairment affects older adults' capacity to live independently and make lifestyle decisions (lifestyle decision-making capacity; LS-DMC). Cognitive screens and clinical interviews are often used to assess people's need for living-supports prior to conducting comprehensive LS-DMC assessments in busy clinical settings. This study investigated whether the QuickSort - a brief new cognitive screen - provides efficient and accurate information regarding patients' LS-DMC when initially interviewed. METHODS This is an observational and diagnostic accuracy study of older inpatients (≥60 years) consecutively referred for neuropsychological assessment of LS-DMC (n = 124). The resources required by inpatients with questionable LS-DMC were quantified (length of hospital stay, living-supports). QuickSort scores, patient background information, and two common cognitive screens were used to differentiate between older inpatients (n = 124) who lacked (64%)/did not-lack (36%) LS-DMC. RESULTS Hospitalizations averaged 49 days, with 62% of inpatients being readmitted within one year. The QuickSort differentiated between those lacking/not-lacking LS-DMC better than two common cognitive screens and patient information. The likelihood that inpatients lacked LS-DMC increased by a factor of 65.26 for QuickSort scores <2 and reduced by a factor of 0.32 for scores ≥13. Modeling revealed that the post-test likelihood of lacking LS-DMC increased to 99% (scores <2) and reduced to 30% (scores ≥ 13) in settings where many inpatients lack LS-DMC. CONCLUSIONS Older adult inpatients with questionable LS-DMC have a high risk of extended hospitalization and readmission. The QuickSort provides time-efficient and sensitive information regarding patients' LS-DMC, making it a viable alternative to longer cognitive screens that are used at the initial interview stage.

Abstract
As the largest ecosystem of human body, intestinal microorganisms participate in the synthesis and metabolism of uric acid. Developing and utilizing intestinal bacteria to degrade uric acid might provide new ideas for the treatment of hyperuricemia. The fecal samples of people with low uric acid were inoculated into uric acid selective medium with the concentration of 1.5 mmol/L for preliminary screening, and the initially screened strains that may have degradation ability were domesticated by concentration gradient method, and the strains with high uric acid degradation rate were identified by 16S rRNA sequencing method. A strain of high-efficiency uric acid degrading bacteria was screened and domesticated from the feces of people with low uric acid. The degradation rate of uric acid could reach 50.2%. It was identified as Escherichia coli. The isolation and domestication of high efficient uric acid degrading strains can not only provide scientific basis for the study of the mechanism of intestinal microbial degradation of uric acid, but also reserve biological strains for the treatment of hyperuricemia and gout in the future.

Abstract
Implementation of the universal newborn hearing screening has changed the landscape for children born deaf or hard of hearing, and with this, pediatricians must be knowledgeable about the screening and referral process, state protocols, and how to support patients and their families in their unique journeys. Early access to language-spoken, signed, both-forms the foundation for successful outcomes for the development of fluent language. For children using spoken language, early access to sound is critical and can often be achieved with the assistance of hearing devices, even in the newborn period. For all language modalities, state-funded Deaf mentor programs allow families to have meaningful exposure to the Deaf community. The authors come from different professions in the health care and education fields, including General Pediatrics, Otolaryngology Head and Neck Surgery, and the state Department of Education, and use different languages, including spoken and American Sign Language.

Abstract
Objective The aim of this study is to investigate the relations of picky eating habit of children with their nutrition, physical activity, screen time and sleep habits in the context of parental picky eating habit. Methods In a cross-sectional study a questionnare was applied to the parents of children aged 6–13 years in two provincies. The cases were analyzed as the overall group and the two subgroups in which both parents are not picky eater, and in which at least one parent was picky eater. Child's risk of being picky eater was analyzed by logistic regression. Results A total of 913 children and parent pairs were included in the study. The risk of picky eating of the child increases 2.85 (AOR: 1.67–4.88) times when only the mother was picky eater, 5.99 (AOR: 3.32–7.52) times when only the father was picky eater, and 22.79 (AOR: 6.95–74.71) times when both of the parents were picky eaters. In the subgroup in which at least one parent was picky eater, it was determined that children with physical activity duration of ≥ 1 h/day and sleep time of ≥ 9 h /day were less likely to be picky eater and the children with screen time of ≥ 2 h/day were more likely to be picky eaters. Conclusion Picky eating habit in childhood is related to the picky eating habit of the parents. In the context of this relationship, the picky eating habit of children is related to sleep, physical activity, screen time and other eating habits.

Abstract
Background Lifestyle behaviour in children and adolescents has become increasingly sedentary and occupied with digital work. Concurrently, there has been an increase in the prevalence of headache, neck- and low back pain, which are leading causes of disability globally. Extensive near work and use of digital devices are demanding for both the visual system and the upper body head-stabilizing musculature. Uncorrected vision problems are present in up to 40% of Nordic school children, and a lack of corrective eye wear may cause eyestrain, musculoskeletal pain and headache. The aim of this study was to investigate associations between laboured reading, musculoskeletal pain, uncorrected vision, and lifestyle behaviours in children and adolescents. Methods This was a cross-sectional study with a total of 192 Norwegian school children aged 10–11 and 15–16 years. As a part of a school vision testing program, the children completed an online questionnaire about general and ocular health, socioeconomic status, academic ambition, near work and related symptoms, upper body musculoskeletal pain, and physical and outdoor activities. Results The 15–16-year-olds had a more indoor, sedentary, digital-based lifestyle with higher academic demands, compared with the 10–11-year-olds. Concurrently, reading became more laboured and upper body musculoskeletal pain increased with age. Girls reported more symptoms, higher academic ambitions, and more time spent on schoolwork and reading, compared with boys. Non-compliance in wearing prescribed eye wear (glasses or contact lenses), increased use of near digital devices, and experiencing visual stress (glare) were positively associated with laboured reading and upper body musculoskeletal pain. Conclusions A screen-based lifestyle with high academic demands challenges the ability to sustain long hours of static, intensive near work. Extensive near work tires the visual system and upper body musculature and provokes laboured reading and musculoskeletal pain symptoms. This study emphasizes the importance of regular eye examinations in school children, and the need to raise awareness among children, parents, and school- and health personnel about the importance of optimal vision and visual environment for academic performance and health.

Abstract
BACKGROUND Falls are the leading cause of injuries among older adults in the United States (US). Falls are preventable and clinicians are advised to screen for fall risk yearly. There are many falls screening tools and not all have been validated for their ability to predict future falls. METHODS We enrolled 1905 community-dwelling older adults into a 13-month study using a probability-based representative panel of the US population recruited from NORC at the University of Chicago's National Frame. Respondents completed a baseline survey, 11 monthly fall calendars, and a final survey. The baseline survey included six falls screening tools (the Stay Independent, Three Key Questions (3KQ), a modified American Geriatric/British Geriatric tool, the short Falls Efficacy-1[FES-I]) and two single screening questions ("I have fallen in the past year" and "How many times did you fall in the past 12 months?"). The baseline and final survey collected demographic and health information, including falls. Sensitivity, specificity, positive and negative likelihood ratios, and corresponding 95% confidence intervals were calculated in SAS using weighted proportions. RESULTS There were 1563 respondents who completed the final survey (completion rate 82%). Sensitivity estimates ranged from 22.5% for the short FES-I to 68.7% for the 3KQ. Specificity estimates ranged from 57.9% for the 3KQ to 89.4% for the short FES-I. CONCLUSIONS Falls screening tools have varying sensitivity and specificity for predicting the occurrence of a fall in the following 12 months.

Abstract
Diagnosis of chronic gastrointestinal and pancreatic diseases is challenging because patients generally present with nonspecific symptoms, such as abdominal pain and chronic diarrhea, some of which can last for many years. Although stool assays are more sensitive than serum assays, the former has unique limitations that healthcare providers should be aware of. One algorithm to screen for chronic gastrointestinal and pancreatic issues is to perform stool testing to assess inflammatory, watery (osmotic) and malabsorptive conditions. This chapter will discuss several stool-based screening tests, the major disorders they screen for and clinical performance. Sections on assay and sample limitations are also included. Stool testing can provide valuable diagnostic, prognostic and treatment response information if both the laboratory and clinician understand the benefits and limitations of these assays.

Abstract
BACKGROUND Tuberculosis (TB) has a serious impact on people's health. China is one of 30 countries that has a high TB burden. As the currently decreasing speed of the incidence of TB, the WHO's goal of "End TB Strategy" is hard to achieve by 2035. As a result, a SEIR model that determines the impact of different tuberculosis preventive treatments (TPTs) in different age groups, and the effect of different interventions on latent TB infections (LTBIs) in China is developed. METHODS A Susceptible-Exposed-Infectious-Recovered (SEIR) model was established. Goodness-of-fit tests were used to assess model performance. Predictive analysis was used to assess the effect of different interventions on LTBIs and achieving the goals of the "End TB Strategy". RESULTS The Chi-square test indicated the model provided a good statistical fit to previous data on the incidence of TB (χ2 = 0.3085, p > 0.999). The 1HP treatment regimen (daily rifapentine + isoniazid for 4 weeks) was most effective in reducing the number of TB cases by 2035. The model indicated that several strategies could achieve the 2035 target of the "End TB Strategy": completion of active case finding (ACF) for LTBI and TPT nation-wide within 5 years; completion of ACF for LTBIs and TPT within 2 years in high-incidence areas; completion of TPT in the elderly within 2 years; or introduction of a new vaccine in which the product of annual doses and vaccine efficiency in the three age groups above 14 years old reached 10.5 million. CONCLUSION The incidence of TB in China declined gradually from 2005 to 2019. Implementation of ACF for LTBIs and TPT nation-wide or in areas with high incidence, in the elderly, or administration of a new and effective vaccine could greatly reduce the number of TB cases and achieve the 2035 target of the "End TB Strategy" in China.

Abstract
OBJECTIVE To investigate the abnormality and distribution of plasma cholesterol levels in single-center hospitalized children. METHODS The blood lipid levels of children aged 2-18 years who had blood lipid test results in Peking University First Hospital from June 2016 to June 2019 were etrospectively analyzed. Cholesterol oxidase method was used for total cholesterol, and high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were detected by clearance method. The counting data were compared with chi-square test. RESULTS The survey had involved 11 829 children (7 087 were boys and 4 742 were girls). 1 822 (15.4%) children were with elevated total cholesterol, 1 371 (11.6%) children with elevated low-density lipoprotein cholesterol, and 2 798 (23.7%) children with high-density lipoprotein cholesterol reduction. The total number of the children with abnormal cholesterol levels was 4 427 (37.4%). Among the 7 835 children who visited hospital due to the disease not commonly inducing dyslipidemia, 731 (9.3%) had elevated TC, 561 (7.2%) had elevated LDL-C, 1 886 (24.1%) had decreased HDL-C, and 2 576 (32.9%) had abnormal cholesterol levels. Among the children with different diseases, the difference in the incidence of abnormal cholesterol was statistically significant. The top three main groups of the children with increased total cholesterol and low-density lipoprotein cholesterol were "dyslipidemia", "urinary tract disease", and "nutritional disease"; The top three main groups of the children with reduced high-density lipoprotein cholesterol were "respiratory diseases", "dyslipidemia", "hematological diseases and malignant tumors". Among the 1 257 blood li-pid test results sent by other departments, 300 cases had abnormal cholesterol levels (23.8%). Among them, there were 70 children with hypercholesterolemia (5.6%), 44 children with increased low-density lipoprotein cholesterol (3.5%), and 224 children with reduced high-density lipoprotein cholesterol (17.8%). There were 365 (4.6%) children with low-density lipoprotein cholesterol ≥140 mg/dL (3.6 mmol/L) who needed to further exclude familiar hypercholesterolemia among the children who visited hospitals due to the disease not commonly inducing dyslipidemia. CONCLUSION Children in hospitals have a high incidence of cholesterol abnormalities. Doctors need to pay more attention to the cholesterol diagnosis and management regardless of the discipline, which not only helps to control secondary hypercholesterolemia, but also provides the possibility of detecting familial hypercholesterolemia in time.

Abstract
Ex vivo culture of primary acute myeloid leukemia (AML) cells is notoriously difficult due to spontaneous differentiation and cell death, which hinders mechanistic and translational studies. To overcome this bottleneck, we have implemented a co-culture system, where the OP9-M2 stromal cells support the growth, but most notably limit the differentiation of primary AML cells, thus allowing for mechanistic studies in vitro. Additionally, the co-culture on OP9-M2 stromal is superior in preserving surface marker expression of primary (adult and pediatric) AML cells in comparison to stroma-free culture. Thus, by combining the co-culture with multicolor, high-throughput FACS, we can evaluate the effect of hundreds of small molecules on multi-parametric processes including: cell survival, stemness (leukemic stem cells), and myeloid differentiation on the primary AML cells at a single-cell level. This method streamlines the identification of potential therapeutic agents, but also facilitates combinatorial screening aiming, for instance, at dissecting the regulatory pathways in a patient-specific manner. Graphic abstract: Schematic representation of the ex vivo small molecule screening of primary human acute myeloid leukemia. Irradiated, sub-confluent OP9-M2 stromal cells are plated in half-area 96 wells plates 4-16 h prior to adding primary AML cells.

Abstract
Colony fitness screens are powerful approaches for functional genomics and genetics. This protocol describes experimental and computational procedures for assaying the fitness of thousands of microbial strains in numerous conditions in parallel. Data analysis is based on pyphe, an all-in-one bioinformatics toolbox for scanning, image analysis, data normalization, and interpretation. We describe a standard protocol where endpoint colony areas are used as fitness proxy and two variations on this, one using colony growth curves and one using colony viability staining with phloxine B. Different strategies for experimental design, normalization and quality control are discussed. Using these approaches, it is possible to collect hundreds of thousands of data points, with low technical noise levels around 5%, in an experiment typically lasting 2 weeks or less.

Abstract
OBJECTIVES The aim of this study was to compare the performance of five sarcopenia screening tools in preoperative patients with gastric cancer, including strength, assistance with walking, rise from a chair, climb stairs, and falls; strength, assistance with walking, rise from a chair, climb stairs, falls, and calf circumference (SARC-CalF); Ishii score chart; short version of the mini sarcopenia risk assessment; and full version of the mini sarcopenia risk assessment. METHODS We conducted a cross-sectional study of consecutive patients undergoing a gastrectomy between May 2020 and October 2020. Sarcopenia was diagnosed per the diagnostic criteria proposed by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2). Data on the five sarcopenia screening tools, patient characteristics, nutrition risk screening 2002, and diagnostic indicators of sarcopenia were collected preoperatively, and pathological characteristics of the tumor were collected postoperatively. Based on the EWGSOP2 criteria, the clinical validity of the sarcopenia tools was measured using sensitivity, specificity, and predictive value. A receiver operator characteristic curve and area under curve were applied to compare the overall screening accuracy, and a Youden index was calculated to determine the optimal cutoff value of each tool. RESULTS We included 260 participants age 62.38 ± 11.21 y. Based on the EWGSOP2 criteria, the prevalence of sarcopenia and severe sarcopenia were 8.46% and 4.62%, respectively. Moreover, the prevalence of sarcopenia risk ranged from 3.46% to 73.85% based on the five screening tools. Of these tools, SARC-CalF had the largest area under the curve (0.896) with moderate-to-high sensitivity (86.36%) and high specificity (92.86%). For SARC-CalF, the cutoff value of 10 reached the highest Youden index, and the corresponding sensitivity and specificity were 81.82% and 93.44%, respectively. CONCLUSION Among the above five screening tools, SARC-CalF appeared to be the optimal choice to screen sarcopenia in preoperative patients with gastric cancer.

Abstract
BACKGROUND/AIMS Given the increased incidence of obstructive sleep apnea (OSA) among patients with nonalcoholic fatty liver disease (NAFLD), noninvasive screening methods are urgently needed to screen for OSA risk in these patients when conducting an office-based assessment of hepatic steatosis. Therefore, we investigated the controlled attenuation parameter (CAP) and hepatic steatosis index (HSI) in patients with and without OSA and developed screening models to detect OSA. METHODS We retrospectively reviewed the medical records of all adult snorers with suspected NAFLD undergoing liver sonography between June 2017 and June 2020. Records encompassed CAP and HSI data as well as data collected during in-hospital full-night polysomnography. The multivariate logistic regression models were constructed to explore the predictors of OSA risk. Furthermore, model validation was performed based on the medical records corresponding to the July 2020-June 2021 period. RESULTS A total of 59 patients were included: 81.4% (48/59) were men, and the mean body mass index (BMI) was 26.4 kg/m2. Among the patients, 62.7% (37/59) and 74.6% (44/59) (detected by the HSI and CAP, respectively) had NAFLD, and 78% (46/59) were diagnosed with OSA on the basis of polysomnography. Three screening models based on multivariate analysis were established. The model combining male sex, a BMI of > 24.8, and an HSI of > 38.3 screened for OSA risk the most accurately, with an area under the receiver operating characteristic curve of 0.81 (sensitivity: 78%; specificity: 85%; and positive and negative predictive values: 95% and 52%, respectively) in the modeling cohort. An accuracy of 70.0% was achieved in the validation group. CONCLUSIONS The combination screening models proposed herein provide a convenient, noninvasive, and rapid screening tool for OSA risk and can be employed while patients receive routine hepatic check-ups. These models can assist physicians in identifying at-risk OSA patients and thus facilitate earlier detection and timely treatment initiation.

Abstract
INTRODUCTION Although three randomized control trials have proven mortality benefit of CT lung cancer screening (CTLS), <5% of eligible US smokers are screened. Some attribute this to fear of harm conveyed at shared decision visits, including the harm of overdiagnosis/overtreatment of indolent BAC-like adenocarcinoma. METHODS Since the frequency of indolent cancers has not been compared between CTLS and routinely detected cohorts, we compare pathology and RNA expression of 86 NCCN high-risk CTLS subjects to 83 high-risk (HR-R) and 51 low-risk (LR-R) routinely detected patients. Indolent adenocarcinoma was defined as previously described for low malignant potential (LMP) adenocarcinoma along with AIS/MIA. Exome RNA sequencing was performed on a subset of high-risk (CTLS and HR-R) FFPE tumor samples. RESULTS Indolent adenocarcinoma (AIS, MIA, and LMP) showed 100% disease-specific survival (DSS) with similar frequency in CTLS (18%) and HR-R (20%) which were comparatively lower than LR-R (33%). Despite this observation, CTLS exhibited intermediate DSS between HR-R and LR-R (5-year DSS: 88% CTLS, 82% HR-R, & 95% LR-R, p = 0.047), possibly reflecting a 0.4 cm smaller median tumor size and lower frequency of tumor necrosis compared to HR-R. WGCNA gene modules derived from TCGA lung adenocarcinoma correlated with aggressive histologic patterns, mitotic activity, and tumor invasive features, but no significant differential expression between CTLS and HR-R was observed. CONCLUSION CTLS subjects are at no greater risk of overdiagnosis from indolent adenocarcinoma (AIS, MIA, and LMP) than risk-matched patients whose cancers are discovered in routine clinical practice. Improved outcomes likely reflect detection and treatment at smaller size.

Abstract
Television studies have shown that some negative effects of screens could depend on exposure time, but more importantly on the characteristics of the child, the type of content viewed, and the context in which it is viewed. Studies on newer screens show that these factors are still valid but new ones now play a negative role: portable screens increase the duration of exposure and lowered the age at which exposure begins. More worryingly, new screen persuasive designs and dark patterns largely used incite more frequent use, attracting the attention of children and parents, resultantly interfering deeply in parent/child relationships. In this text we suggest that current academic recommendations have to be more broadly shared but also that new recommendations are needed: especially to advise parents not to let their screen interactions compete with real interactions with their child which are the core of learnings (especially language) and emotional regulations but also of their security.

Abstract
Enhancers are critical cis-regulatory elements that regulate spatiotemporal gene expression and control cell fates. However, the identification of enhancers in native cellular contexts still remains a challenge. Here, we develop an inducible CRISPR activation (CRISPRa) system by transgenic expression of doxycycline (Dox)-inducible dCas9-VPR in mouse embryonic stem cells (iVPR ESC). With this line, a simple introduction of specific guide RNAs targeting promoters or enhancers allows us to realize the effect of CRISPRa in an inducible, reversible, and Dox concentration-dependent manner. Taking advantage of this system, we induce tiled CRISPRa across genomic regions (105 kilobases) surrounding T (Brachyury), one of the key mesodermal development regulator genes. Moreover, we identify several CRISPRa-responsive elements with chromatin features of putative enhancers, including a region the homologous sequence in which humans harbors a body height risk variant. Genetic deletion of this region in ESC does affect subsequent T gene activation and osteogenic differentiation. Therefore, our inducible CRISPRa ESC line provides a convenient platform for high-throughput screens of putative enhancers.

Abstract
BACKGROUND The Fist-Edge-Palm (FEP) test takes 0.5-3 min to complete and is highly sensitive in differentiating Alzheimer's disease and frontotemporal dementia from normal cognition, but it has not yet been studied in Parkinson's disease (PD). OBJECTIVE To determine the sensitivity and specificity of the FEP test in screening patients with PD for cognitive impairment and dementia. METHODS PD patients were recruited and divided into three groups based on cognitive status: normal cognition, mild cognitive impairment (MCI) and dementia according to 2015 MDS clinical diagnostic criteria for PD and clinical dementia rating scale (CDR) assessment for cognitive status. MMSE, FEP and clock drawing test (CDT) were tested in all recruited PD patients. Chi-square test was used to compare the sensitivity of FEP and CDT in detecting PDD and PD-MCI. RESULTS A total of 108 PD patients were included: 52 normal cognition, 28 MCI, and 28 dementia. The sensitivity of FEP in differentiating PDD from PD-NC was 96.4% and the sensitivity for PD-MCI from PD-NC was 71.4%. The sensitivity of CDT in differentiating PDD from PD-NC was 71.4% and PD-MCI from PD-NC was 53.6%. The sensitivities of FEP and CDT were 83.9% and 62.5%, respectively, in identifying cognitive impairment (CDR ≥ 0.5) in PD patients. CONCLUSION FEP is a sensitive screening tool in differentiating PDD or PD-MCI from PD-NC, and it is much faster than MMSE and more sensitive than CDT. FEP may be a practical screening tool for daily clinical practice.

Abstract
We have screened a collection of UAS-RNAi lines targeting 10,920 Drosophila protein-coding genes for phenotypes in the adult wing. We identified 3653 genes (33%) whose knockdown causes either larval/pupal lethality or a mutant phenotype affecting the formation of a normal wing. The most frequent phenotypes consist of changes in wing size, vein differentiation, and patterning, defects in the wing margin and in the apposition of the dorsal and ventral wing surfaces. We also defined 16 functional categories encompassing the most relevant aspect of each protein function and assigned each Drosophila gene to one of these functional groups. This allowed us to identify which mutant phenotypes are enriched within each functional group. Finally, we used previously published gene expression datasets to determine which genes are or are not expressed in the wing disc. Integrating expression, phenotypic and molecular information offers considerable precision to identify the relevant genes affecting wing formation and the biological processes regulated by them.

Abstract
This study was designed to evaluate iVue Spectral-domain optical coherence tomography (SD-OCT) effectiveness in screening for eye disease compared to clinical examination. Subjects were recruited from the Casey Eye Community Outreach Program Mobile Clinic during its routinely scheduled outreach clinics to indigent, underserved populations throughout Oregon. Macular optical coherence tomography interpretation and automated optical coherence tomography analysis were compared to the clinical examination, with specific attention to findings indicative of retinal abnormalities, risks for glaucoma, and narrow angles. As a result, a total of 114 subjects were included in this study. In diabetics, optical coherence tomography and clinical exam were in fair agreement (kappa = 0.39), with 22% of eyes having abnormal findings on macular optical coherence tomography and 26% of eyes having diabetic retinopathy or diabetic macular edema on fundus exam. In non-diabetics, optical coherence tomography and clinical exam were in fair agreement (kappa = 0.28), with 11% of eyes having abnormal findings on macular optical coherence tomography and 9% on fundus exam. Using optical coherence tomography ganglion cell complex and retinal nerve fiber layer analysis, 18% of eyes were found to be glaucoma suspects, whereas clinical exam of cup-to-disc ratio detected 8% and intraocular pressure 5%. Agreements between optical coherence tomography and other methods were poor (kappa < 0.11) for glaucoma suspect. Anterior segment optical coherence tomography of the angle found 8% of eyes to have occludable angles, whereas slit lamp and gonioscopy found 5% of eyes to have narrow angles, with moderate agreement (kappa = 0.57). In summary, optical coherence tomography detected additional retinal abnormalities, glaucoma suspects, and narrow angles compared to clinical exam alone and may serve as a useful adjunct to the clinical exam in screening for eye disease in a low-risk, medically underserved, ethnically diverse population.

A comprehensive screening method that is specific, accurate, and customizable is necessary in any forensic toxicology laboratory. Most laboratories utilize some form of immunoassay testing as it is reliable and sensitive with minimal sample preparation and is relatively inexpensive to simultaneously screen for multiple classes of drugs with different chemical properties. However, accessibility to more specific technology and instrumentation such as mass spectrometry has increased and therefore using immunoassay as the screening method of choice may be revisited. A screening method for 42 drugs in postmortem blood was developed and validated following the Organization of Scientific Area Committees for Forensic Science (OSAC) guidelines for toxicology method validation. The method was developed using minimal sample preparation of postmortem blood consisting only of a protein precipitation. Only two internal standards were used which greatly reduces the cost of implementing this method. Limit of detection (LOD), interference studies, processed sample stability and ion suppression/enhancement were examined. Additionally, over 100 case samples were analyzed by both the current enzyme linked immunosorbent assay (ELISA) testing procedure and the proposed liquid chromatography tandem mass spectrometry (LC-MS/MS) screening method. The comparison determined that the LC/MS-MS method performed as well as or better than the ELISA in nearly all cases. The ability to add additional target drugs increases the laboratory's scope of analysis as well. This method is ideal for forensic laboratories wishing to improve screening while working within budget constraints.

Abstract
Screening and follow-up of interstitial lung disease associated with rheumatoid arthritis (RA-ILD) is a challenge in clinical practice. In fact, the majority of RA-ILD patients are asymptomatic and optimal tools for early screening and regular follow-up are lacking. Furthermore, some patients may remain oligosymptomatic despite significant radiological abnormalities. In RA-ILD, usual interstitial pneumonia (UIP) is the most frequent radiological and pathological pattern, associated with a poor prognosis and a high risk to develop acute exacerbations and infections. If RA-ILD can be identified early, there may be an opportunity for an early treatment and close follow-up that might delay ILD progression and improve the long-term outcome.In connective tissue disease-associated interstitial lung disease (CTD-ILD), lung ultrasound (LUS) with the assessment of B-lines and serum Krebs von den Lungen-6 antigen (KL-6) has been recognized as sensitive biomarkers for the early detection of ILD. B-line number and serum KL-6 level were found to correlate with high-resolution computed tomography (HRCT), pulmonary function tests (PFTs), and other clinical parameters in systemic sclerosis-associated ILD (SSc-ILD). Recently, the significant correlation between B-lines and KL-6, two non-ionizing and non-invasive biomarkers, was demonstrated. Hence, the combined use of LUS and KL-6 to screen and follow up ILD in RA patients might be useful in clinical practice in addition to existing tools. Herein, we review relevant literature to support this concept, propose a preliminary screening algorithm, and present 2 cases where the algorithm was used.

Abstract
Metastasis is the main cause of cancer morbidity and mortality. Cancer stem cells (CSCs) are a rare subpopulation of cancer cells that can drive metastasis. The identification of CSC inhibitors and CSC-related genes is an alluring strategy for suppressing metastasis. Here, we established a simple and repeatable high-throughput CSC inhibitor screening platform that combined tumor sphere formation assays and cell viability assays. Human lung cancer cells were cocultured with 1280 pharmacologically active compounds (FDA-approved). Fifty-four candidate compounds obtained from our screening system completely or partially inhibited tumor sphere formation. A total of 5 of these 54 compounds (prochlorperazine dimaleate, thioridazine hydrochloride, ciproxifan hydrochloride, Ro 25-6981 hydrochloride, and AMN 082) completely inhibited the self-renewal of CSCs without cytotoxicity in vitro via their targets and suppressed lung cancer metastasis in vivo, suggesting that our screening platform is selective and reliable. DRD2, HRH3, and GRIN2B exhibited potent genes promoting CSCs in vitro experiments and clinical datasets. Further validation of the top hit (DRD2) and previously published studies demonstrate that our screening platform is a useful tool for CSC inhibitor and CSC-related gene screening.

Abstract
Dysphagia is a common complication of cardiac surgery (CS) contributing to morbidity and mortality. Although early dysphagia detection is important, no current screening guidelines or validated tools exist in the cardiac intensive care setting. We therefore aimed to examine the discriminant ability of the 3-ounce water swallow test (3 oz. WST) to detect aspiration in acute postoperative CS patients. 196 postoperative CS patients were enrolled in this prospective single-center study. Participants completed the 3 oz. WST and a standardized Flexible Endoscopic Evaluation of Swallowing. Independent duplicate ratings of the penetration aspiration scale (PAS) were performed in a blinded fashion (100% agreement criteria). Receiver operating characteristic curve and area under the curve (AUC) analyses were performed with sensitivity, specificity, positive, and negative predictive values (PPV, NPV) derived. Fifty-four CS patients (28%) were confirmed aspirators (PAS ≥ 6), of whom 48% (n = 26) were silent aspirators (PAS = 8). Both the sensitivity and specificity of the 3 oz. WST to identify instrumentally confirmed aspiration was 63% (AUC: 0.63, 95% CI: 0.54, 0.72), and PPV was 39% and NPV 82%. The 3 oz. WST demonstrated fair discriminant ability to detect aspiration in acute postoperative CS patients. The high rate of silent aspiration may explain, in part, these findings given that the screening fail criteria include an overt cough response. In isolation, the 3 oz. WST does not represent a sensitive screen of aspiration in postoperative CS patients with a need to identify alternative screening tools for this setting.

Abstract
Viral hepatitis C is one of the important causes of liver cirrhosis and hepatocellular carcinoma. There are approximately 10 million cases of chronic hepatitis C virus (HCV) infection in China. However, over 70% of HCV infections of China have not yet been detected. According to the goal of "eliminating viral hepatitis as a public health threat by 2030" of the World Health Organization Viral Hepatitis Strategy, and the fact that medical institutions remain the main places for detecting HCV infections or patients in China at present, we established the " In-hospital process for viral hepatitis C screening and management in China (Draft)", with intention to promote the multidisciplinary collaboration and cooperation among the departments of clinic, laboratory, infection control, management, and etc. in medical institutions, and strengthen consultation and referral of patients with detected HCV antibodies and advance the diagnosis and antiviral treatment of patients with chronic hepatitis C.

Abstract
Adult Attention-Deficit/Hyperactivity Disorder (ADHD) is prevalent but often overlooked and undertreated. Left untreated, it is linked to increased risk of untoward outcomes including unemployment, relationship breakups, substance use, driving accidents and other mental health conditions. Several brief screening tools have been developed for adult ADHD. The most frequently used is the World Health Organization's Adult ADHD Self-Report Scale (ASRS V1.1). Here, we show in two independent population samples (UK: N = 642, USA: N = 579) that the tool resulted in considerable overestimation of ADHD, indicating probable ADHD in 26.0% and 17.3% of participants, as compared to expected prevalence of 2.5%. The estimated positive predictive value was only ~11.5%. Both samples had normal levels of trait impulsivity as assessed using the Barratt Impulsiveness Scale. The data indicate that using the ASRS in general population samples will result in 7-10 times over-identification of ADHD. We use these results to highlight how such tools should most appropriately be used. When being used to determine possible cases (such as for onward referral to an ADHD specialist) they should be complemented by clinical assessment - we give examples of how non-specialists might determine this. When measuring ADHD symptoms dimensionally, researchers should be mindful that the ASRS captures impulsive symptoms other than those due to ADHD. Lastly, we note the need to screen for impulse control disorders (e.g., gambling disorder) when using such tools to measure ADHD, be it for onward referral, or for dimensional research studies.

Abstract
BACKGROUND Sniffer dogs are able to detect certain chemical particles and are suggest to be capable of helping diagnose some medical conditions and complications, such as colorectal cancer, melanoma, bladder cancer, and even critical states such as hypoglycemia in diabetic patients. With the global spread of COVID-19 throughout the world and the need to have a real-time screening of the population, especially in crowded places, this study aimed to investigate the applicability of sniffer dogs to carry out such a task. METHODS Firstly, three male and female dogs from German shepherd (Saray), German black (Kuzhi) and Labrador (Marco) breeds had been intensively trained throughout the classical conditioning method for 7 weeks. They were introduced to human specimens obtained from the throat and pharyngeal secretions of participants who were already reported positive or negative for SARS-COV-2 infection be RT-PCR. Each dog underwent the conditioning process for almost 1000 times. In the meantime another similar condition process was conducted on clothes and masks of COVID-19 patient using another three male and female dogs from Labrador (Lexi), Border gypsy (Sami), and Golden retriever (Zhico) breeds. In verification test for the first three dogs, 80 pharyngeal secretion samples consisting of 26 positive and 54 negative samples from different medical centers who underwent RT-PCR test were in a single-blind method. In the second verification test for the other three dogs, masks and clothes of 50 RT-PCR positive and 70 RT-PCR negative cases from different medical center were used. RESULTS In verification test using pharyngeal secretion, the sniffer dogs' detection capability was associated with a 65% of sensitivity and 89% of specificity and they amanged to identify 17 out of the 26 positive and 48 out of the 54 true negative samples. In the next verification test using patients' face masks and clothes, 43 out of the 50 positive samples were correctly identified by the dogs. Moreover, out of the 70 negative samples, 65 samples were correctly found to be negative. The sensitivity of this test was as high as 86% and its specificity was 92.9%. In addition, the positive and negative predictive values were 89.6 and 90.3%, respectively. CONCLUSION Dogs are capable of being trained to identify COVID-19 cases by sniffing their odour, so they can be used as a reliable tool in limited screening.

Abstract
BACKGROUNDS The incidence of thyroid nodules is increasing year by year around the world. However, ultrasound is not recommended as a screening test for the general population or patients with a normal thyroid on palpation by the American Association of Clinical Endocrinologists (AACE). In practice, some individuals with normal thyroid palpation have nodules that can just be found out by ultrasound. No studies have directly described the risk of nodules found by ultrasound or by palpation up to now. More evidence is needed to carry out for helping us balance the over diagnosis and missed diagnosis of malignant lesions. Therefore, we carried out a retrospective study to investigate the incidence of malignant lesions in ultrasound-found nodules in a large cohort. METHODS We conducted a retrospective analysis involving 2957 patients who underwent thyroid ultrasound evaluation and fine-needle aspiration (FNA) between Jan 2013 and Dec 2019. The cytologic examinations were analyzed based on the Bethesda system. For nodules suspected to be follicular neoplasm or other malignant tumors by cytological tests, patients were recommended for surgery and histopathology examinations. RESULTS Compared with palpation-found nodules, ultrasound-found nodules were presenting less as purely cystic nodules (10.1 % vs. 39.9 %, x2 = 355.69, p = 0.000), smaller size (17.5 ± 9.9 mm vs. 28.0 ± 12.5 mm, t = 23.876 p = 0.000), and higher TI-RADS score (5.5 ± 2.9 vs. 3.4 ± 3.3, t = 18.084, p = 0.000), respectively. More ultrasound-found nodules were diagnosed as carcinoma by histology examinations [136 (11.2 %) nodules found by ultrasound vs. 68 (3.9 %) by palpation, x2 = 59.737, p = 0.000], and 88 (64.7 %) nodules found by ultrasound were non-microcarcinoma. Among the malignant nodules confirmed by histopathology, a higher proportion of microcarcinoma was detected in ultrasound-found nodules [35.3 % (48/136) vs. 16.2 % (11/68), x2 = 8.183, p = 0.004]. CONCLUSIONS In view of the results observed in our research, malignant nodules were more common in nodules screened out by ultrasound, and nearly two thirds of them were non-microcarcinoma. We suggest the recommendation against screening thyroid nodules by ultrasound needs to be re-evaluated.

Abstract
STUDY OBJECTIVE The objective of this study was to determine if performing a methicillin-resistant Staphylococcus aureus (MRSA) nasal screen in the emergency department (ED) decreased general medicine patient exposure to anti-MRSA antibiotics for pneumonia. METHODS This was a single-center, retrospective study evaluating patients who had a diagnosis of pneumonia and were initiated on anti-MRSA therapy (vancomycin or linezolid) in the ED and subsequently admitted to a general medicine floor. Patients were divided into two groups: 1) did not receive a MRSA nares screen in the ED (No MRSA screen group) or 2) received a MRSA nares screen in the ED (MRSA screen group). The primary outcome was anti-MRSA antibiotic duration. Secondary outcomes included vancomycin level evaluation, hospital survival, and acute kidney injury. RESULTS Of the 116 patients included, 37 patients received a MRSA nares screen in the ED and 79 patients did not. Median duration of antibiotic exposure was similar for both groups (No MRSA screen, 30.5 h [interquartile range (IQR) 20.5-52.5] vs. MRSA screen, 24.5 h [IQR 20.6-40.3]; p = 0.28). Of patients who were screened, 35 were negative and 2 were positive. Secondary outcomes were similar. CONCLUSION Performing a MRSA nares screen in the ED for patients diagnosed with pneumonia, initiated on anti-MRSA antibiotics, and admitted to a general medicine floor did not decrease duration of anti-MRSA antibiotics. At this time, ED providers do not need to consider a MRSA nasal screen in the ED for patients being admitted to general medicine, although larger studies could be considered.

Abstract
BACKGROUND The aims of this study were to explore to explore the viewpoints of parents of children with Autism Spectrum Disorders (ASD) and professionals regarding the implementation of screening programs for ASD, to explore the challenges of the implementation of a universal screening program for ASD in Iran from their viewpoints, and, to explore their recommendations to overcome the potential challenges. METHOD This qualitative study was conducted using an inductive content analysis, between June 2018 and December 2018, in East-Azerbaijan province of Iran. Data was collected through in-depth interviews and focus group discussions. The participants were purposively selected among two groups: representatives of health system and representatives of children with ASD. A sample of 32 parents and 30 professionals were recruited in this study. RESULTS Totally, 9 main themes and 23 sub-themes were extracted in three main areas including: viewpoints of the participants about universal screening for ASD, challenges in implementation of the universal screening program, and participants' recommendations about how to overcome the potential challenges. Main challenges in implementation of the universal screening program included: shortages of ASD screening tools, weakness of the health system, lack of coordination among the ASD service providers, and social and ethical issues. CONCLUSION The parents and the professionals had different viewpoints about the implementation of ASD universal screening program in Iran. According to the professionals, there is not enough rational to implement ASD screening program for all children. However, the parents believed that universal screening program is inevitable, and it should be implemented in primary health centers during the early child-care visits. The results of this study open up unspoken issues that could help in initiating the screening program not only in Iran but also in other low- and middle-income countries as well.

Abstract
Background The detection of drug-resistant tuberculosis (DR-TB) is a major health concern in China. We aim to summarize interventions related to the screening and detection of DR-TB in Jiangsu Province, analyse their impact, and highlight policy implications for improving the prevention and control of DR-TB. Methods We selected six prefectures from south, central and north Jiangsu Province. We reviewed policy documents between 2008 and 2019, and extracted routine TB patient registration data from the TB Information Management System (TBIMS) between 2013 and 2019. We used the High-quality Health System Framework to structure the analysis. We performed statistical analysis and logistic regression to assess the impact of different policy interventions on DR-TB detection. Results Three prefectures in Jiangsu introduced DR-TB related interventions between 2008 and 2010 in partnership with the Global Fund to Fight AIDS, Tuberculosis and Malaria (the Global Fund) and the Bill & Melinda Gates Foundation (Gates Foundation). By 2017, all prefectures in Jiangsu had implemented provincial level DR-TB policies, such as use of rapid molecular tests (RMT), and expanded drug susceptibility testing (DST) for populations at risk of DR-TB. The percentage of pulmonary TB cases confirmed by bacteriology increased from 30.0% in 2013 to over 50.0% in all prefectures by 2019, indicating that the implementation of new diagnostics has provided more sensitive testing results than the traditional smear microscopy. At the same time, the proportion of bacteriologically confirmed cases tested for drug resistance has increased substantially, indicating that the intervention of expanding the coverage of DST has reached more of the population at risk of DR-TB. Prefectures that implemented interventions with support from the Global Fund and the Gates Foundation had better detection performance of DR-TB patiens compared to those did not receive external support. However, the disparities in DR-TB detection across prefectures significantly narrowed after the implementation of provincial DR-TB polices. Conclusions The introduction of new diagnostics, including RMT, have improved the detection of DR-TB. Prefectures that received support from the Global Fund and the Gates Foundation had better detection of DR-TB. Additionally, the implementation of provincial DR-TB polices led to improvements in the detection of DR-TB across all prefectures. ![]()

Abstract
We report the development, automation and validation of a 3D, microfluidic liver-on-a-chip for high throughput hepatotoxicity screening, the OrganoPlate LiverTox™. The model is comprised of aggregates of induced pluripotent stem cell (iPSC)-derived hepatocytes (iHep) seeded in an extracellular matrix in the organ channel and co-cultured with endothelial cells and THP-1 monoblasts differentiated to macrophages seeded in the vascular channel of the 96 well Mimetas OrganoPlate 2-lane. A key component of high throughput screening is automation and we report a protocol to seed, dose, collect and replenish media and add assay reagents in the OrganoPlate 2-lane using a standard laboratory liquid handling robot. A combination of secretome measurements and image-based analysis was used to demonstrate stable 15 day cell viability, albumin and urea secretion. Over the same time-period, CYP3A4 activity increased and alpha-fetoprotein secretion decreased suggesting further maturation of the iHeps. Troglitazone, a clinical hepatotoxin, was chosen as a control compound for validation studies. Albumin, urea, hepatocyte nuclear size and viability staining provided Robust Z'factors > 0.2 in plates treated 72 h with 180 μM troglitazone compared with a vehicle control. The viability assay provided the most robust statistic for a Robust Z' factor = 0.6. A small library of 159 compounds with known liver effects was added to the OrganoPlate LiverTox model for 72 h at 50 μM and the Toxicological Prioritization scores were calculated. A follow up dose-response evaluation of select hits revealed the albumin assay to be the most sensitive in calculating TC50 values. This platform provides a robust, novel model which can be used for high throughput hepatotoxicity screening.
