Empowering the helping hands: A positive psychological intervention for enhancing work engagement and reducing stress among preschool social workers in Hong Kong.

This study explores the efficacy of the Early Advancement in Social-Emotional Health and Positivity (EASP) programme, designed to enhance personal resources, namely self-compassion and positivity among preschool social workers, to reduce stress and bolster work engagement. A total of 84 preschool social workers (Mage = 32.47 years, SD = 6.86, range = 22-55; female = 90.48%) participated in a 5-week randomized control trial. Participants were randomly allocated to either the intervention group (n = 38), which received four online workshops and an online activity, or the wait-list control group (n = 46), which received the intervention post-data collection. Self-compassion, positivity, work engagement, and work stress were measured before and after the intervention. Results from a path analytic model indicated excellent fit with the data, χ2 = 2.08, df = 3, Comparative Fit Index = 1.00, Tucker-Lewis Index = 1.00, Root Mean Square Error of Approximation = 0.00 (90% CI = 0.00-0.16), SRMR = 0.03. The intervention demonstrated direct effects on changes in self-compassion (ß = 0.21, p = 0.04) and positivity (ß = 0.28, p = 0.03), with indirect effects on work engagement (ß = 0.13, p = 0.02), while no significant impact was observed on work stress (ß = -0.09, p = 0.06). These findings underscore the efficacy of positive psychological interventions in fostering work engagement among social workers. Incorporating the EASP programme into ongoing professional development activities is recommended to enhance the job engagement and psychological well-being of social workers in early childhood education and care sectors.

Structure Elucidation of Pharmaceutically Relevant Compounds within Pyrene-based Frameworks.

Single crystal X-ray diffraction (SCXRD) is the preferred and most accurate technique for determining molecular structures. However, it can present challenges when dealing with specific small molecules and active pharmaceutical ingredients (APIs), as many do not form quality crystals without coformers or can be unstable. In this study, we introduce tetrakis(guanidinium) pyrenetetrasulfonate (G4PYR), a robust guanidinium-organosulfonate (GS) framework that efficiently encapsulates small molecules and APIs rich in functional groups. The hydrogen bonding frameworks formed by G4PYR display well-ordered structures with predictable pyrene-pyrene distances, making them ideally suited for targeting arene-based APIs with pendant groups. Successful encapsulation of various guests, including benzaldehyde, benzamide, and arenes containing multiple hydrogen bond donors and acceptors like uracil and thymine, was achieved. Furthermore, we successfully encapsulated important pharmaceutical and biologically relevant compounds, such as lidocaine, ropinirole, adenosine, thymidine, and others. Notably, we present a workflow for investigating host-guest complex formation using powder X-ray diffraction and high throughput experimentation.

Evaluating the impact of a year-long external mentorship pilot program in classical hematology.

Effective mentorship is a pivotal factor in shaping the career trajectory of trainees interested in classical hematology (CH), which is of critical importance due to the anticipated decline in the CH workforce. However, there is a lack of mentorship opportunities within CH compared with medical oncology. To address this need, a year-long external mentorship program was implemented through the American Society of Hematology (ASH) Medical Educators Institute (MEI). Thirty-five hematology/oncology (H/O) fellows interested in CH and 34 academically productive faculty mentors from different institutions across North America were paired in a meticulous process that considered individual interests, experiences, and background. Pairs were expected to meet virtually once a month. Participation in a scholarly project was optional. A mixed-methods sequential explanatory design was used to evaluate the program using mentee and mentor surveys, a mentee interview, and a mentee focus group. Thirty-three (94.2%) mentee-mentor pairs completed the program. Sixty-three percent of mentee respondents worked on a scholarly project with their mentor; several mentees earned publications, grants, and awards. Mentee perception that their assigned mentor was a good match was associated with a perceived positive impact on confidence (p=0.0423), career development (p=0.0423), and professional identity (p=0.0302). Furthermore, twenty-three (66%) mentees accepted CH faculty positions after fellowship. All mentor respondents believed that this program would increase retention in CH. This mentorship program demonstrates a productive, beneficial way of connecting mentees and mentors from different institutions to improve the careers of CH trainees, with the ultimate goal of increasing retention in CH.

Predicting antibiotic susceptibility in urinary tract infection with artificial intelligence-model performance in a multi-centre cohort.

Objective: To develop an artificial intelligence model to predict an antimicrobial susceptibility pattern in patients with urinary tract infection (UTI). Materials and methods: 26 087 adult patients with culture-proven UTI during 2015-2020 from a university teaching hospital and three community hospitals in Hong Kong were included. Cases with asymptomatic bacteriuria (absence of diagnosis code of UTI, or absence of leucocytes in urine microscopy) were excluded. Patients from 2015 to 2019 were included in the training set, while patients from the year 2020 were included as the test set.Three first-line antibiotics were chosen for prediction of susceptibility in the bacterial isolates causing UTI: namely nitrofurantoin, ciprofloxacin and amoxicillin-clavulanate. Baseline epidemiological factors, previous antimicrobial consumption, medical history and previous culture results were included as features. Logistic regression and random forest were applied to the dataset. Models were evaluated by F1-score and area under the curve-receiver operating characteristic (AUC-ROC). Results: Random forest was the best algorithm in predicting susceptibility of the three antibiotics (nitrofurantoin, amoxicillin-clavulanate and ciprofloxacin). The AUC-ROC values were 0.941, 0.939 and 0.937, respectively. The F1 scores were 0.938, 0.928 and 0.906 respectively. Conclusions: Random forest model may aid judicious empirical antibiotics use in UTI. Given the reasonable performance and accuracy, these accurate models may aid clinicians in choosing between different first-line antibiotics for UTI.

Trainees' perspectives on sickle cell education: a qualitative needs assessment.

BACKGROUND: Sickle cell disease (SCD) exemplifies many of the social, racial, and healthcare equity issues in the United States. Despite its high morbidity, mortality, and cost of care, SCD has not been prioritized in research and clinical teaching, resulting in under-trained clinicians and a poor evidence base for managing complications of the disease. This study aimed to perform a needs assessment, examining the perspectives of medical trainees pursuing hematology/oncology subspecialty training regarding SCD-focused education and clinical care. METHOD: Inductive, iterative thematic analysis was used to explore qualitative interviews of subspecialty hematology-oncology trainees' attitudes and preferences for education on the management of patients with SCD. Fifteen trainees from six programs in the United States participated in 4 focus groups between April and May 2023. RESULTS: Thematic analysis resulted in 3 themes: 1. Discomfort caring for patients with SCD. 2. Challenges managing complications of SCD, and 3. Desire for SCD specific education. Patient care challenges included the complexity of managing SCD complications, limited evidence to guide practice, and healthcare bias. Skill-building challenges included lack of longitudinal exposure, access to expert clinicians, and didactics. CONCLUSIONS: Variations in exposure, limited formal didactics, and a lack of national standardization for SCD education during training contributes to trainees' discomfort and challenges in managing SCD, which in turn, contribute to decreased interest in entering the SCD workforce. The findings underscore the need for ACGME competency amendments, dedicated SCD rotations, and standardized didactics to address the gaps in SCD education.

Factor VIII Levels and ISTH Disseminated Intravascular Coagulation Scores Do Not Distinguish Disseminated Intravascular Coagulation from the Coagulopathy of Liver Disease.

INTRODUCTION: Distinguishing disseminated intravascular coagulation (DIC) from the coagulopathy of liver disease represents a common clinical challenge. Here, we evaluated the utility of two diagnostic tools frequently used to differentiate between these conditions: factor VIII (FVIII) levels and the International Society on Thrombosis and Hemostasis (ISTH) DIC score. METHODS: To this end, we conducted a retrospective chart review of patients with DIC, liver disease, or both. Multiple logistic regression was performed, and receiver operating characteristic curves were generated to calculate the area under curve (AUC) for distinguishing DIC in the setting of liver disease. RESULTS: Among 123 patients with DIC, liver disease, or liver disease plus DIC, FVIII levels did not differ significantly. ISTH scores were lower in patients with DIC than in liver disease with or without DIC. Addition of several laboratory parameters to the ISTH score, including mean platelet volume, FV, FVIII, international normalized ratio, and activated partial thromboplastin time, improved AUC for distinguishing DIC in liver disease from liver disease alone (AUC = 0.76; p < 0.0001). CONCLUSION: We conclude that FVIII levels do not distinguish DIC from liver disease, and ISTH DIC scores are not predictive of DIC in patients with liver disease. Inclusion of additional lab variables within the ISTH DIC score may aid in identifying DIC in patients with liver disease.

Unprecedented Packing Polymorphism of Oxindole: An Exploration Inspired by Crystal Structure Prediction.

Crystal polymorphism, characterized by different packing arrangements of the same compound, strongly ties to the physical properties of a molecule. Determining the polymorphic landscape is complex and time-consuming, with the number of experimentally observed polymorphs varying widely from molecule to molecule. Furthermore, disappearing polymorphs, the phenomenon whereby experimentally observed forms cannot be reproduced, pose a significant challenge for the pharmaceutical industry. Herein, we focused on oxindole (OX), a small rigid molecule with four known polymorphs, including a reported disappearing form. Using crystal structure prediction (CSP), we assessed OX solid-state landscape and thermodynamic stability by comparing predicted structures with experimentally known forms. We then performed melt and solution crystallization in bulk and nanoconfinement to validate our predictions. These experiments successfully reproduced the known forms and led to the discovery of four novel polymorphs. Our approach provided insights into reconstructing disappearing polymorphs and building more comprehensive polymorph landscapes. These results also establish a new record of packing polymorphism for rigid molecules.

Risk of Invasive Fungal Infections in Patients With Chronic Lymphocytic Leukemia Treated With Bruton Tyrosine Kinase Inhibitors: A Case-Control Propensity Score-Matched Analysis.

Background: Prior reports have suggested a possible increase in the frequency of invasive fungal infections (IFIs) with use of a Bruton tyrosine kinase inhibitor (BTKi) for treatment of chronic lymphoid malignancies such as chronic lymphocytic leukemia (CLL), but precise estimates are lacking. We aim to characterize the prevalence of IFIs among patients with CLL, for whom a BTKi is now the first-line recommended therapy. Methods: We queried TriNetX, a global research network database, to identify adult patients with CLL using the International Classification of Diseases, Tenth Revision code (C91.1) and laboratory results. We performed a case-control propensity score-matched analysis to determine IFIs events by BTKi use. We adjusted for age, sex, ethnicity, and clinical risk factors associated with an increased risk of IFIs. Results: Among 5358 matched patients with CLL, we found an incidence of 4.6% of IFIs in patients on a BTKi versus 3.5% among patients not on a BTKi at 5 years. Approximately 1% of patients with CLL developed an IFI while on a BTKi within this period. Our adjusted IFI event analysis found an elevated rate of Pneumocystis jirovecii pneumonia (PJP) (0.5% vs 0.3%, P = .02) and invasive candidiasis (3.5% vs 2.7%, P = .012) with the use of a BTKi. The number needed to harm for patients taking a BTKi was 120 and 358 for invasive candidiasis and PJP, respectively. Conclusions: We found an adjusted elevated rate of PJP and invasive candidiasis with BTKi use. The rates are, however, low with a high number needed to harm. Additional studies stratifying other IFIs with specific BTKis are required to identify at-risk patients and preventive, cost-effective interventions.

Cost-effectiveness of sutimlimab in cold agglutinin disease.

Primary cold agglutinin disease (CAD) is a rare autoimmune hemolytic anemia caused by cold-reactive antibodies that bind to red blood cells and lead to complement-mediated hemolysis. Patients with primary CAD experience the burden of increased health resource utilization and reduced quality of life. The standard-of-care (SOC) in patients with primary CAD has included cold avoidance, transfusion support, and chemoimmunotherapy. The use of sutimlimab, a humanized monoclonal antibody that selectively inhibits C1-mediated hemolysis, was shown to reduce transfusion-dependence and improve quality of life across two pivotal phase 3 studies, further supported by 2-year extension data. Using data from the transfusion-dependent patient population that led to sutimlimab's initial FDA approval, we performed the first-ever cost-effectiveness analysis in primary CAD. The projected incremental cost-effectiveness ratio (ICER) in our Markov model was $2 340 000/QALY, significantly above an upper-end conventional US willingness-to-pay threshold of $150 000/QALY. These results are consistent across scenarios of higher body weight and a pan-refractory SOC patient phenotype (i.e., treated sequentially with bendamustine-rituximab, bortezomib, ibrutinib, and eculizumab). No parameter variations in deterministic sensitivity analyses changed our conclusion. In probabilistic sensitivity analysis, SOC was favored over sutimlimab in 100% of 10 000 iterations. Exploratory threshold analyses showed that significant price reduction (>80%) or time-limited treatment (<18 months) followed by lifelong clinical remission off sutimlimab would allow sutimlimab to become cost-effective. The impact of sutimlimab on health system costs with longer term follow-up data merits future study and consideration through a distributional cost-effectiveness framework.

Benchmarking Guanidinium Organosulfonate Hydrogen-Bonded Frameworks for Structure Determination of Encapsulated Guests.

Single crystal X-ray diffraction (SCXRD) is arguably the most definitive method for molecular structure determination, but it is often challenged by compounds that are liquids or oils at room temperature or do not form crystals adequate for analysis. Our laboratory previously reported a simple, cost-effective, single-step crystallization method based on guanidinium organosulfonate (GS) hydrogen bonded frameworks for structure determination of a wide range of encapsulated guest molecules, including assignment of the absolute configuration of chiral centers. Herein, we expand on those results and report a head-to-head comparison of the GS method with adamantoid "molecular chaperones", which have been reported to be useful hosts for structure determination. Inclusion compounds limited to only two GS hosts are characterized by low R1 values and Flack parameters, infrequent disorder of the host and guest, and manageable disorder when it does exist. The structures of some target molecules that were not included or resolved using the adamantoid chaperones were successfully included and resolved by the GS hosts, and vice versa. Of the 32 guests attempted by the GS method, 31 inclusion compounds afforded successful guest structure solutions, a 97% success rate. The GS hosts and adamantoid chaperones are complementary with respect to guest inclusion, arguing that both should be employed in the arsenal of methods for structure determination. Furthermore, the low cost of organosulfonate host components promises an accessible route to molecular structure determination for a wide range of users.

The effectiveness of a positive psychological intervention for promoting preschool teachers' well-being and professional competence: EASP intervention program.

The present study investigated the effectiveness of the Early Advancement in Social-Emotional Health and Positivity (EASP) program, a positive psychological intervention promoting preschool teachers' well-being and the motivational aspect of professional competence. Participants were 273 in-service preschool teachers (Mage = 34.56 years, SD = 9.52, range = 22-58; female = 98.90%) who participated in a 2-month randomized controlled trial. Participants were randomly assigned to the intervention group (n = 143) receiving 1) four online workshops, 2) a smartphone app, and 3) an online activity, or to the wait-list control group (n = 130), which received the intervention materials after all the data collection. Participants reported their well-being dimensions, teaching self-efficacy, and autonomous motivation for teaching before and after the intervention. Results from a path analytic model exhibited excellent fit with the data, χ2 = 37.62, df = 33, CFI = .99, TLI = .98, RMSEA = .02 [90% CI = 0.00, 0.05], SRMR = .02. The intervention had direct effects on changes in well-being dimensions, including positivity, outcome, strength, engagement, and resilience (ß = .14 to .26, ps = .00 to .04), and indirect intervention effects on changes in teaching self-efficacy and autonomous motivation for teaching (ß = .14 to .15, ps = .00 to .01). These findings highlighted the potential value of implementing positive psychological interventions in educational settings to promote the well-being and professional competence among preschool teachers.

Comparison of carbapenem MIC for NDM-producing Enterobacterales by different AST methods.

Introduction: This study compared the performance of MIC test strip (ETEST), automated AST card (Vitek 2) and broth microdilution (BMD) in determining carbapenem susceptibility and MIC values of NDM-producing Enterobacterales. Methods: NDM-producing Enterobacterales recovered from clinical specimens were included. The presence of blaNDM was confirmed by PCR. Identification of bacterial isolates was done by MALDI-TOF. Phenotypic susceptibility to three carbapenems (ertapenem, imipenem and meropenem) was tested by BMD, ETEST and Vitek 2. MIC values were interpreted in accordance with CLSI M100 (2022 edition). Using BMD as the reference standard, the essential agreement (EA), categorical agreement (CA), very major error (VME) and major error (ME) rates were evaluated. Results: Forty-seven NDM-producing Enterobacterales isolates were included, 44 of which were Escherichia coli. The EA of Vitek 2 was 97.9% for ertapenem, 25.5% for meropenem and 42.6% for imipenem. Using Vitek 2, there were 0% VMEs across all three carbapenems tested. The EA of ETEST was 53.2% for ertapenem, 55.3% for imipenem and 36.2% for meropenem. The rates of VMEs for ETEST were high too (ertapenem 8.5%, meropenem 36.2%, imipenem 26.1%). The MIC values obtained from Vitek 2 were consistently higher than those from BMD, while MICs from ETEST were consistently lower than those from BMD. Conclusions: The VME rate for ETEST was unacceptably high when BMD was used as the standard for comparison. Vitek 2 had acceptable EA and CA for ertapenem when BMD was used as the standard for comparison. For meropenem and imipenem, neither of the methods (ETEST, Vitek 2) showed acceptable EA and CA when compared with BMD.

Tracking and predicting the treatment adherence of patients under rehabilitation: a three-wave longitudinal validation study for the Rehabilitation Adherence Inventory.

This study aimed to develop and validate a new measurement tool, the Rehabilitation Adherence Inventory (RAI), to measure patients' rehabilitation adherence. We recruited 236 patients with anterior cruciate ligament (ACL) ruptures from the United Kingdom (Mage = 33.58 ± 10.03, range = 18 to 59; female = 46.2%). Participants completed a survey, that measured their rehabilitation adherence, rehabilitation volume, psychological needs support, autonomous motivation, and intention at baseline, and at the 2nd and 4th month. Factorial, convergent, discriminant, concurrent, predictive, ecological validity and test-retest reliability of the RAI were tested via exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equation modelling (SEM). All the EFAs, CFAs, and SEMs yielded acceptable to excellent goodness-of-fit, χ2 = 10.51 to 224.12, df = 9 to 161, CFI > 0.95, TLI > 0.95, RMSEA <0.09 [90%C I < 0.06 to 0.12], SRMR <0.04. Results fully supported the RAI's factorial, convergent, discriminant, and ecological validity, and test-retest reliability. The concurrent and predictive validity of the RAI was only partially supported because the RAI scores at baseline was positively associated with rehabilitation frequency at all time points (r = 0.34 to 0.38, p < 0.001), but its corresponding associations with rehabilitation duration were not statistically significant (p = 0.07 to 0.93). Overall, our findings suggest that this six-item RAI is a reliable and valid tool for evaluating patients' rehabilitation adherence.

Formation, Selective Encapsulation, and Tautomerization Control of Isoindolone Utilizing Guanidinium Sulfonate Frameworks.

Herein we report the use of tetrakis (guanidinium) pyrenetetrasulfonate (G4PYR) and bis (guanidinium) 1,5-napthalene disulfonate (G2NDS) to catalyze the cyclization of 2-cyanobenzamide (1) to isoindolone (2). Moreover, we demonstrate the remarkable selectivity of these guanidinium organosulfonate hosts in encapsulating 2 over 1. By thoroughly investigating the intramolecular cyclization reaction, we determined that guanidinium and the organosulfonate moiety acts as the catalyst in this process. Additionally, 2 is selectively encapsulated, even in mixtures of other structurally similar heterocycles like indole. Furthermore, the tautomeric state of 2 (amino isoindolone (2-A) and imino isoindolinone forms (2-I)) can be controlled by utilizing different guanidinium organosulfonate frameworks.

Supramolecular Mille-Feuille: Adaptive Guest Inclusion in a New Aliphatic Guanidinium Monosulfonate Hydrogen-Bonded Framework.

During the past three decades, the ability of guanidinium arenesulfonate host frameworks to encapsulate a wide range of guests has been amply demonstrated, with more than 700 inclusion compounds realized. Herein, we report crystalline inclusion compounds based on a new aliphatic host, guanidinium cyclohexanemonosulfonate, which surprisingly exhibits four heretofore unobserved architectures, as described by the projection topologies of the organosulfonate residues above and below hydrogen-bonded guanidinium sulfonate sheets. The inclusion compounds adopt a layer motif of guanidinium sulfonate sheets interleaved with guest molecules, resembling a mille-feuille pastry. The aliphatic character of this remarkably simple host, combined with access to greater architectural diversity and adaptability, enables the host framework to accommodate a wide range of guests and promises to expand the utility of guanidinium organosulfonate hosts.

Providing 0.1 Full-Time Equivalent (FTE) Support to Fellowship Core Faculty Improves Faculty Involvement in Fellowship Education and Recruitment.

In 2022, the American Council for Graduate Medical Education (ACGME) recommended that core faculty (CF) in medical subspecialty fellowships receive at least 0.1 full-time equivalent (FTE) salary support, with plans to enforce compliance in July 2023. After early feedback raised concerns about potential unintended consequences, ACGME deferred enforcement to July 2024. Hence, there is an urgent need to understand the ramifications of providing FTE support for CF. In 2020, the Yale hematology and medical oncology (HO) fellowship program began providing 0.1 FTE support to all CF. Perceptions regarding this were assessed via surveys distributed to all CF in 2021 and 2022 and to all HO fellows in 2021. The vast majority (83.3%) of CF survey respondents reported improved job satisfaction and an increased sense of involvement in the fellowship program as a result of the new 0.1 FTE-supported CF program. Most CF increased attendance at fellowship conferences, devoted more time to mentorship, and increased participation in recruitment. In free text comments, CF respondents described that providing 0.1 FTE support made them "feel rewarded," gave them "a sense of commitment" to the fellowship, and helped "offset clinical requirements." HO fellows reported "a positive impact" of the new program with faculty being "more present at lectures." The median number of times faculty were available to interview fellowship applicants rose markedly after introduction of the program. The FTE-supported CF program was viewed enthusiastically by fellows and faculty, resulting in increased CF involvement in fellowship education and recruitment.

Endovascular treatment of renal vein thrombosis in a young patient with lung transplant.

Spontaneous renal vein thrombosis is a rare entity. A 28-year-old woman with a history of a double-lung transplant was admitted with flank pain and found to have acute kidney injury. A magnetic resonance venogram demonstrated isolated left renal vein thrombosis with extension into the inferior vena cava. Initial management with therapeutic anticoagulation and hydration was unsuccessful. Thus, pharmacochemical thrombectomy was performed. A temporary suprarenal inferior vena cava filter was placed for intraoperative pulmonary prophylaxis. The patient's renal function returned to baseline and remained normal 13 months later. Early incorporation of percutaneous pharmacomechanical thrombectomy can improve renal function when medical therapy alone is unsuccessful.

Can a multicomponent positive psychological intervention promote well-being in parents of young children? A randomized controlled trial study in Hong Kong.

The present research examined the effects of an Early Advancement in Social-Emotional Health and Positivity (EASP) multicomponent positive psychological intervention on parents' well-being in Hong Kong. Participants were parents of young children (N = 120; Mage = 37.19 years, SD = 4.71, range = 24-53; female = 95.00%) who participated in the one-month randomized control trial. Participants were randomly assigned into the intervention (n = 50) and waitlist control groups (n = 70). Parents in the intervention group received two online workshops and an evidence-based smartphone application that targeted four positive psychological skills: (1) mindful parenting, (2) hope, (3) positive reappraisal, and (4) growth mindset. The results of the multivariate regression analysis revealed that the intervention significantly improved various dimensions of participants' positive psychological skills, subjective well-being, and psychological well-being immediately at the conclusion of the program. The findings of this study underscore the importance of the well-being payoffs linked to cultivating positive psychological skills among parents of young children.

A machine learning-based risk score for prediction of infective endocarditis among patients with Staphylococcus aureus bacteraemia - The SABIER score.

BACKGROUND: Early risk assessment is needed to stratify Staphylococcus aureus infective endocarditis (SA-IE) risk among Staphylococcus aureus bacteraemia (SAB) patients to guide clinical management. The objective of this study is to develop a novel risk score independent of subjective clinical judgment and can be used early at the time of blood culture positivity. METHODS: We conducted a retrospective big data analysis from territory-wide electronic data and included hospitalized patients with SAB between 2009 and 2019. We applied a random forest risk scoring model to select variables from an array of parameters, according to the statistical importance of each feature in predicting SA-IE outcome. The data was divided into derivation and validation cohorts. The areas under the curve of the receiver operating characteristic (AUCROC) were determined. RESULTS: We identified 15,741 SAB patients, among them 4.18% had SA-IE. The AUCROC was 0.74 (95%CI 0.70-0.76), with a negative predictive value of 0.980 (95%CI 0.977-0.983). The four most discriminatory features were age, history of infective endocarditis, valvular heart disease, and being community-onset. CONCLUSION: We developed a novel risk score with good performance as compared to existing scores and can be used at the time of SAB and prior to subjective clinical judgment.

Are General Anxiety, Reading Anxiety, and Reading Self-Concept Linked to Reading Skills Among Chinese Adolescents With and Without Dyslexia?

This study investigated the cross-sectional relationships between reading-related affective and cognitive factors and reading skills among adolescents with and without dyslexia. Participants were 120 Chinese-speaking eighth graders, including 60 adolescents with dyslexia and 60 typically developing adolescents from Hong Kong, China. Adolescents completed questionnaires on general anxiety, reading anxiety, and reading self-concept. They were also assessed on measures of rapid digit naming, verbal working memory, word reading, reading fluency, and reading comprehension. The results showed that readers with dyslexia reported higher levels of general anxiety and reading anxiety and lower levels of reading self-concept than typical readers. They also showed difficulties in rapid digit naming and verbal working memory. Importantly, controlling for rapid digit naming and verbal working memory, reading self-concept was uniquely associated with word reading and reading fluency for readers with and without dyslexia. Furthermore, reading anxiety and reading self-concept were uniquely associated with reading comprehension for the two groups of readers. The findings point to the importance of considering affective factors when examining the reading skills of Chinese readers and the utility of targeting these factors when supporting the learning of adolescents with and without dyslexia.
