Abstract
Frontotemporal dementia (FTD) is an incurable group of early-onset dementias that can be caused by the deposition of hyperphosphorylated tau in patient brains. However, the mechanisms leading to neurodegeneration remain largely unknown. Here, we combined single-cell analyses of FTD patient brains with a stem cell culture and transplantation model of FTD. We identified disease phenotypes in FTD neurons carrying the MAPT-N279K mutation, which were related to oxidative stress, oxidative phosphorylation, and neuroinflammation with an upregulation of the inflammation-associated protein osteopontin (OPN). Human FTD neurons survived less and elicited an increased microglial response after transplantation into the mouse forebrain, which we further characterized by single nucleus RNA sequencing of microdissected grafts. Notably, downregulation of OPN in engrafted FTD neurons resulted in improved engraftment and reduced microglial infiltration, indicating an immune-modulatory role of OPN in patient neurons, which may represent a potential therapeutic target in FTD.

Abstract
OBJECTIVES To evaluate the reliability of data from the assay of bio-archived specimens, a 50-freeze-thaw-cycle (FTC) degradation study of fresh sera was conducted to test the stability of 16 immunoregulators. METHODS Twenty de-identified serum specimens were obtained from volunteers at United Health Services-Wilson Memorial Hospital. Specimens were stored at -20°C and underwent daily 1 h thawing and subsequent freezing for each FTC over 50 consecutive days. Immunoregulator concentrations were assessed via enzyme-linked immunosorbent assay (ELISA) in participant samples at 2 FTC (baseline), 25 FTC, and 50 FTC. Specific immunoregulators observed in the study were C-reactive protein (CRP), interleukin (IL)-1α, 4, 6, 8, 10, monocyte chemoattractant protein-1 (MCP-1, CCL2), monocyte chemoattractant protein-2 (MCP-2, CCL8), eotaxin-1, thymus-and-activation-regulated chemokine (TARC, CCL17), regulated on activation normal T-cell expressed and secreted (RANTES, CCL5), growth-regulated oncogene-alpha (GRO-α, CXCL1), small inducible cytokine A1 (I-309, CCL1), interferon-gamma (IFN-γ), interferon-gamma inducible protein-10 (IP-10, CXCL10), and tumor necrosis factor-alpha (TNF-α). RESULTS Quantitative stability of serum immunoregulators: Serum CRP, IL-8, IL-10, IFN-γ, IP-10, and eotaxin-1 levels appear to be statistically equivalent from baseline to 50 FTC (p ≤ .05). Retention of patterns in serum immunoregulators: patterns across FTC were retained for TARC (age) and CRP, IFN-γ, and MCP-2 (sex). CONCLUSIONS While the effect of multiple FTC on serum immunoregulator levels may not replicate prolonged freezer storage, the results of this study provide valuable information on the robustness of immunoregulators for research using bio-archived sera.

Abstract
This experiment aimed to determine the effect of adaptive duration to saline water on behaviors, weight gain and blood biochemical parameters in growing goats. The experiment was arranged in a completely randomized design, which included four treatments with five animals per group. The goats were administered either fresh water (control) or seawater with a salinity of 1.5%, with varying durations of adaptation to seawater. The adaptive durations included an abrupt change (A0) from fresh water to seawater with a salinity of 1.5% or stepwise adaptation either 4 (A4) or 7 (A7) days of increasing saline concentrations. The results showed that dry matter intake in the non-adapted goats (A0 group) was lower than that of the control group or the adapted goats throughout the experiment (p<0.05). In contrast, water intake from drinking saline water was greater than that in the control group (p<0.05). Body weigh did not differ among the treatments; however, non-adapted goats exhibited a lower weight gain than the adapted goats (p<0.05). The goats in the A0 and A4 groups exhibited increased plasma levels of urea, AST, and ALT compared with the control and A7 groups. However, blood electrolyte levels remained unchanged and were within the normal range for goats. Therefore, it is concluded that the stepwise adaptation to seawater with a salinity of 1.5% for 21 days has no influence on productivity and health status of goats.

Abstract
Investigation of Lewis acid-base interactions has been conducted by ab initio calculations and machine learning (ML) models. This study aims to resolve two critical tasks that have not been quantitatively investigated. First, ML models developed from density functional theory (DFT) calculations predict experimental BF3 affinity with Pearson correlation coefficients around 0.9 and mean absolute errors around 10 kJ mol-1 . The ML models are trained by DFT-calculated BF3 affinity of more than 3000 adducts, with input features readily obtained by rdkit. Second, the ML models have the capability of predicting the relative strength of Lewis base binding atoms in Lewis polybases, which is either an extremely challenging task to conduct experimentally or a computationally expensive task for ab initio methods. The study demonstrates and solidifies the potential of combining DFT calculations and ML models to predict experimental properties, especially those that are scarce and impractical to empirically acquire.

Abstract
PURPOSE To determine the distribution of diagnosed SARS-CoV-2 infections by testing modality (at-home rapid antigen [home tests] versus laboratory-based tests in clinical settings [clinical tests]), assess factors associated with clinical testing, and estimate the true total number of diagnosed infections in New York State (NYS). METHODS We conducted an online survey among NYS residents and analyzed data from 1012 adults and 246 children with diagnosed infection July 13-December 7, 2022. Weighted descriptive and logistic regression model analyses were conducted. Weighted percentages and prevalence ratios by testing modality were generated. The percent of infections diagnosed by clinical tests via survey data were synthesized with daily lab-reported results to estimate the total number of diagnosed SARS-CoV-2 infections in NYS July 1-December 31, 2022. RESULTS Over 70% of SARS-CoV-2 infections in NYS during the study period were diagnosed exclusively with home tests. Diagnosis with a clinical test was associated with age, race/ethnicity, and region among adults, and sex, age, and education among children. We estimate 4.1 million NYS residents had diagnosed SARS-CoV-2 infection July 1-December 31, 2022, compared to 1.1 million infections reported over the same period. CONCLUSIONS Most SARS-CoV-2 infections in NYS were diagnosed exclusively with home tests. Surveillance metrics using laboratory-based reporting data underestimate diagnosed infections.

Abstract
OBJECTIVES To assess the prevalence of depressive symptoms and associated factors among people living with HIV (PLWH) who were current cigarette smokers and receiving treatment at HIV outpatient clinics (OPCs) in Vietnam. DESIGN A cross-sectional survey of smokers living with HIV. SETTING The study was carried out in 13 HIV OPCs located in Ha Noi, Vietnam. PARTICIPANTS The study included 527 PLWH aged 18 and above who were smokers and were receiving treatment at HIV OPCs. OUTCOME MEASURES The study used the Centre for Epidemiology Scale for Depression to assess depressive symptoms. The associations between depressive symptoms, tobacco dependence and other characteristics were explored using bivariate and Poisson regression analyses. RESULTS The prevalence of depressive symptoms among smokers living with HIV was 38.3%. HIV-positive smokers who were female (prevalence ratio, PR 1.51, 95% CI 1.02 to 2.22), unmarried (PR 2.06, 95% CI 1.54 to 2.76), had a higher level of tobacco dependence (PR 1.06, 95% CI 1.01 to 1.11) and reported their health as fair or poor (PR 1.66, 95% CI 1.22 to 2.26) were more likely to have depression symptoms compared with HIV-positive smokers who were male, married, had a lower level of tobacco dependence and self-reported their health as good, very good or excellent. CONCLUSION The prevalence of depressive symptoms among smokers receiving HIV care at HIV OPCs was high. Both depression and tobacco use screening and treatment should be included as part of ongoing care treatment plans at HIV OPCs.

Abstract
Whole genome sequencing has increasingly become the essential method for studying the genetic mechanisms of antimicrobial resistance and for surveillance of drug-resistant bacterial pathogens. The majority of bacterial genomes sequenced to date have been sequenced with Illumina sequencing technology, owing to its high-throughput, excellent sequence accuracy, and low cost. However, because of the short-read nature of the technology, these assemblies are fragmented into large numbers of contigs, hindering the obtaining of full information of the genome. We develop Pasa, a graph-based algorithm that utilizes the pangenome graph and the assembly graph information to improve scaffolding quality. By leveraging the population information of the bacteria species, Pasa is able to utilize the linkage information of the gene families of the species to resolve the contig graph of the assembly. We show that our method outperforms the current state of the arts in terms of accuracy, and at the same time, is computationally efficient to be applied to a large number of existing draft assemblies.

Abstract
Whipple disease (WD) is a rare infection in genetically susceptible people caused by the bacterium Tropheryma whipplei. An indirect immunofluorescence serological assay (IFA), detecting patient antibodies to the bacterium, was developed using T. whipplei as antigen. We hypothesised that this assay could be used to rule out WD in patients in whom the diagnosis was being considered, based on high immunoglobulin (Ig) G titres to T. whipplei. In this study, 16 confirmed WD patients and 156 age-matched controls from across Australia were compared serologically. WD patients mostly underproduced IgG antibody to T. whipplei, with titres of ≤1:32 being common. While at an antibody titre of <1:64 the assay sensitivity for WD was only 69% [95% confidence interval (CI) 41-89%], its specificity for excluding WD was 91% (95% CI 85-95%). This specificity increased to 95% (95% CI 90-98%) at an antibody titre of <1:16. Patients with antibody titres of >1:64 were unlikely to have WD. At this titre, the seroprevalence of T. whipplei IgG antibody was 92% (223/242) in Australian blood donors. Unlike other serological assays, which are used to confirm a specific infection, this novel assay is designed to rule out WD infection with a specificity in Australia of 91%. Further validation of this assay, by trialling in other countries, should now be undertaken, as its usefulness is dependent on there being a high background seropositivity to T. whipplei in the general population at the location in which the assay is being used.

Abstract
BACKGROUND Depression is a common mental disorder that significantly contributes to the global burden of disease. Studies have consistently reported that migrant workers experience higher levels of depressive symptoms, especially women. AIMS This study aimed to examine the mediation role of sexual self-efficacy on the relationship between psychological wellbeing, and depressive symptoms among young female migrant workers in Vietnam's industrial zones. METHODS A cross-sectional study was conducted among 1061 female migrant workers aged 18 to 29 from January to November 2020 in Hanoi, Vietnam. Anonymous interview questionnaires were used to collect data on demographic characteristics, psychosocial wellbeing (PWB), sexual self-efficacy, and depressive symptoms. Mediation analysis was conducted to explore the mediation effect of sexual self-efficacy on the relationship between PWB and depressive symptoms. RESULTS Nearly 8% of the female migrant workers reported experiencing depressive symptoms. The final mediation model showed that the effect of overall psychological wellbeing on depressive symptoms was partially mediated by sexual self-efficacy. Specifically, 4.1% of the effect of overall PWB on depressive symptoms was mediated through sexual self-efficacy. In the PWB subdimension analyses, sexual self-efficacy mediated 14.3% of the effect of personal growth, 8.8% of the effect of purpose in life, 8.0% of the effect of autonomy, and 7.8% of the effect of environmental mastery on depressive symptoms, respectively. CONCLUSION The study findings demonstrate that sexual self-efficacy plays an important role in the relationship between psychosocial wellbeing and depressive symptoms among female migrant workers in industrial zones in Vietnam. Improving psychosocial wellbeing and promoting sexual health including sexual self-efficacy should be prioritized when addressing depressive symptoms and mental health concerns among industrial zone female migrant workers in Vietnam, which may also be applicable in other low- and middle-income countries with similar socio-cultural settings.

Abstract
IMPORTANCE The use of adeno-associated viruses (AAVs) as gene delivery vectors has vast potential for the treatment of many severe human diseases. Over one hundred naturally existing AAV capsid variants have been described and classified into phylogenetic clades based on their sequences. AAV8, AAV9, AAVrh.10, and other intensively studied capsids have been propelled into pre-clinical and clinical use, and more recently, marketed products; however, less-studied capsids may also have desirable properties (e.g., potency differences, tissue tropism, reduced immunogenicity, etc.) that have yet to be thoroughly described. These data will help build a broader structure-function knowledge base in the field, present capsid engineering opportunities, and enable the use of novel capsids with unique properties.

Abstract
Developmental and lifespan examinations of methamphetamine use among gay, bisexual, and other men who have sex with men (GBM) remain limited. We used a feminist trauma framework to examine potential links between childhood trauma, trauma-related stressors, and methamphetamine use among GBM. From June 2018 to October 2018, semi-structured interviews (N = 33) were conducted with GBM across British Columbia. Interviews focused on sexual experiences, support services, and methamphetamine use. Using thematic analysis, two overarching trauma-related themes were identified: developmental and insidious trauma and coping with trauma-related stressors. GBM's methamphetamine use co-occurred with childhood experiences of family- and peer-perpetrated heterosexism, childhood sexual abuse, and intersecting forms of oppression/marginalization. These experiences manifested as internalized shame, interpersonal anxiety, and low self-esteem. In adulthood, participants reported difficulty managing emotions, low self-confidence, and loneliness. GBM reported using methamphetamine to manage negative emotions, life stressors, and overcome barriers to interpersonal connection. Findings indicate a need for trauma-informed interventions that address underlying issues and help GBM cultivate supportive relationships.

Abstract
Issue Successful response to an infodemic requires social listening and integrated analysis to produce infodemic insights by identifying questions, concerns, information voids and circulating narratives including health misinformation. There is currently a wide variation in social listening and infodemic insights generation practices, and a lack of frameworks to be applied on ethical values and standards. Description of the problem In the context of infodemic management, infodemic insights are generated based on social listening, health system and data from online and offline sources. Where there is a difference between health guidance and behaviors during an emergency, rapid infodemic insights can help understand the underlying drivers of this divergence. Integrated analysis of this data informs infodemic management strategies generate insights that advise a wide range of public health interventions. Present ethical challenges influence data processing and use. Results The World Health Organization (WHO) convened a group of experts to develop an ethical framework for social listening and infodemic management. It will guide health authorities and practitioners in planning and setting up infodemic insights teams and implementing infodemic management activities. To support the deliberation of the WHO expert group, a systematic review has been conducted to understand present ethical concerns and challenges. Lessons Infodemic management strategies raise ethical concerns that relate to data control, commercialization, transparency, accountability and implications. Power and power imbalances, human rights, privacy and dignity, trust and respect for cultural practices may arise during data collection, analysis, interpretation, and intervention design. Without proper ethical oversight and guidance, the implementation of infodemic management strategies could harm individuals and communities, erode trust, and undermine the effectiveness of responses to a public health emergency. Key messages • Social listening and infodemic management by health authorities require consideration of ethical principles and guidance. • WHO ethics guidance will help public health authorities establish infodemic management practices, policies and strategies.

Abstract
BACKGROUND Young migrant workers living in low- and middle-income countries often experience barriers and inadequate access to HIV prevention and treatment services. This study examines the prevalence of HIV testing, associated factors, and reasons for obtaining and not obtaining HIV testing among young sexually active women migrant workers in an industrial zone in Hanoi, Vietnam. METHODS A cross-sectional study was conducted among 512 sexually active young women migrant workers (aged 18 to 29) working in the Thang Long industrial zone in Hanoi, Vietnam. Data was collected via a face-to-face interview from January 2020 to June 2021. Multivariable logistic regression analysis was used to explore factors associated with ever-testing for HIV among sexually active participants. RESULTS The study found a low level of HIV testing and high rates of unprotected sex. Among those who reported being sexually active, only 23.7% of participants (n = 126) reported having ever been tested for HIV. Among those who reported never having tested for HIV, 38.2% reported not using condoms during their most recent sexual encounter. Factors associated with engaging in HIV testing included being older (25-29 years), having greater knowledge about HIV, past use of sexual and reproductive health and HIV services, and familiarity with HIV testing locations. CONCLUSIONS Overall, a low level of HIV testing, high rates of unprotected sex, and low perceived risks regarding HIV among the study participants point to a need to implement targeted HIV interventions that can improve both safe sex practices and perceptions of and knowledge about risky sexual behaviors. Such interventions should use insights from this study to address factors facilitating HIV testing among industrial zones' women migrant workers.

Abstract
PURPOSE/OBJECTIVE(S) Glioblastoma multiforme (GBM) is a lethal CNS malignancy. Radiation therapy increases overall survival, but tumors often recur in high-radiation dose regions. Additionally, recent investigations have underscored the importance of intra-tumoral heterogeneity as a driver of GBM biology. The purpose of this investigation is to characterize transcriptome differences in primary and recurrent GBM patient clinical samples using a digital spatial profiling approach to better appreciate treatment resistance mechanisms. MATERIALS/METHODS To address the lack of understanding of molecular mechanisms of resistance in GBM, patient-matched primary and recurrent GBM pathological specimens were identified within the brain tissue biorepository and tissue cores were selected for generation of a tissue microarray (TMA). Hematoxylin and eosin staining with histomorphological (cellular tumor, pseudopalisading necrosis, invasive edge, and perivascular inflammation) scoring were performed in a blinded fashion for every core. This array was then molecularly characterized using digital spatial profiling of the transcriptome. Quality assurance including filtering of lowly expressed genes followed by downstream analyses of the data were performed using the manufacturer's recommended methods within their Bioconductor library. Gene Set Enrichment Analysis (GSEA) was then performed on the ranked gene lists. RESULTS After recommended filtering, 6171 genes and 248 regions of interest remained for downstream analysis representing 22 unique patients across four different tumor histomorphological types. Significance testing revealed 679 genes that were differentially expressed between primary and recurrent tumor samples (at FDR<1%). On GSEA analysis, the chromosomal positional locus that contains genes most strongly up-regulated is 12q14, a locus that was previously identified as genomically amplified in multiple patient-derived xenograft lines after radiation selection. Additionally, recurrent tumors display a transcriptional profile more similar to the mesenchymal subtype, whereas primary tumors have a more classical transcriptional phenotype. The epithelial-to-mesenchymal transition pathway is particularly strongly up-regulated in recurrent tumors. CONCLUSION Recurrent selection at previously identified genomic loci and molecular pathways underscores a possible conserved set of pathways for treatment resistance. This analysis has yielded a set of gene and molecular pathways that will guide future work in our lab targeting treatment resistance using novel therapeutics and radiation techniques in GBM. Future directions include assessing the feasibility of mapping these clinical samples onto our previously generated panel of comprehensively characterized patient-derived xenograft lines.

Abstract
PURPOSE/OBJECTIVE(S) TP53 mutations appear to be enriched over the spectrum of metastatic castration-sensitive prostate cancer (mCSPC) and are associated with worse survival outcomes. We chose to further explore the impact of dominant negative (DN) TP53 mutations on mCSPC progression and pro-metastatic behaviors in addition to studying the ability of APR-246, a small molecule targeting TP53 mutants, to blunt pro-metastatic behaviors. MATERIALS/METHODS We retrospectively analyzed 531 mCSPC patients who underwent next-generation sequencing. Patients were stratified by metastasis timing (synchronous if metastasis present at diagnosis or metachronous if arising after definitive treatment of localized disease) and the number of metastatic lesions (oligometastatic ≤5 or polymetastatic >5 lesions). Tumors were classified based on TP53 mutation status (missense, truncating, or wild-type [WT]) and dominant negativity, which was defined as the production of a mutant protein that reduces the residual WT protein's transcriptional activity according to the World Health Organization TP53 database. Clinical outcomes were radiographic progression-free survival (rPFS) and overall survival (OS), evaluated with Kaplan-Meier and multivariable Cox regression. To verify the impact of TP53 mutation on metastasis, we created isogenic 22Rv1 prostate cancer cell lines that carried either TP53 WT or TP53 R175H and tested this mutation for migration, invasion, and anchorage-independent growth. APR-246 (25-80 µM) was tested for anti-metastatic properties in vitro and anti-tumor growth in 22Rv1 xenografted nude mice. RESULTS In our cohort, 155 (29.2%) had a TP53 mutation, which mostly occurred in the DNA-binding domain (85.16%). DN TP53 mutations were associated with more aggressive disease states: DN TP53 mutations were enriched in patients with synchronous (vs. metachronous: 20.7% vs. 6.3%, p < 0.01) and polymetastatic disease (vs. oligometastatic: 14.4% vs. 7.9%, p < 0.01). On multivariable analysis, DN TP53 mutations were correlated with shorter rPFS (HR = 1.97, 95% CI: 1.31-2.98, p < 0.01) and OS (HR = 2.05, 95% CI: 1.14-3.68, p = 0.02) compared to those with TP53 WT. In vitro, 22Rv1 cells with DN TP53 R175H mutation had increased abilities to migrate, invade, and form colonies compared to TP53 WT. APR-246 treatment of TP53 R175H mutants blunted the pro-metastatic effects of the cell line in vitro (p < 0.01 for all assays by unpaired t-test). Interestingly, APR-246 also inhibited xenograft tumor growth of 22Rv1 TP53 R175H mutants (p < 0.0001 by two-way ANOVA). CONCLUSION DN TP53 mutations were associated with poorer survival outcomes for mCSPC patients. DN TP53 mutations also promoted prostate cancer pro-metastatic behaviors in vitro, which was effectively counteracted by APR-246, making it a promising treatment option that should be explored further in early-phase clinical studies.

Abstract
PURPOSE/OBJECTIVE(S) Cost effectiveness analyses (CEA) provide data for health policy decisions in resource constrained environments. These are important in Radiation Oncology as infrastructure and delivery costs increase and indications expand. The purpose of this study was to systematically review methodologic quality and trends in CEAs involving radiotherapy (RT). MATERIALS/METHODS A systematic review was performed on cost effectiveness/utility studies involving RT, querying PubMed and Embase from inception to September 2020. Non-English, reviews, abstracts and cost-only studies were excluded. Independent reviewers screened and abstracted study demographics, economic parameters and methodological details. RESULTS After screening 1652 abstracts, 214 met criteria. The first publication was in 1995, and more than half (n = 113, 53%) were published after 2014. Author institutions were from North America (n = 128, 60%), Europe (n = 49, 23%) and Asia (n = 30, 14%) with most reporting in US$ (n = 143, 67%). A majority utilized a decision model (n = 164, 77%), healthcare payer perspective (n = 171, 80%) and a finite time horizon (n = 108, 50%). Publications spanned 96 unique journals, most commonly International Journal of Radiation and Oncological Biology and Physics (n = 35, 16%). Treatment intent was curative in 171 studies. Disease sites included breast (n = 34, 16%), genitourinary (n = 31, 14%), and gastrointestinal (n = 31, 14%). RT was mostly used as primary treatment (n = 144, 67%), followed by adjuvant (n = 70, 33%) and neoadjuvant (n = 10, 5%). Emerging topics included stereotactic RT (n = 45, 21%), immunotherapy (n = 6, 3%), oligometastasis (n = 4, 2%), and heavy particles (n = 23, 11%). RT was compared to other RT (n = 136, 64%), surgery (n = 43, 20%), drugs (n = 14, 7%) and observation (n = 31, 17%). Incomplete reporting was common. Missing elements included analysis perspective (n = 13, 6%), time horizon (n = 38, 18%), discounting of utilities (n = 71, 33%) or costs (n = 54, 25%), and willingness-to-pay threshold (n = 59, 28%). Furthermore, 27 studies did not perform sensitivity analyses, 36 did not evaluate incremental cost-effectiveness ratio and only 60 explicitly utilized recognized reporting guidelines. Conflict of interest statements were found in 63%, with sponsor statements in 59%; 25% were industry sponsors. Outcome parameters were obtained from primary (author institution/trial data) sources in 33%, including randomized trials (RCTs) (n = 20, 9%), retrospective data (n = 20, 9%) and population data (n = 9, 4%). The remainder utilized secondary sources including RCTs (n = 71, 33%), retrospective data (n = 35, 16%) or meta-analyses (n = 11, 5%). Outcomes included quality adjusted life years (n = 158, 74%), life-years (n = 30, 14%) or toxicity (n = 26,12%). 31% utilized author generated utilities; of literature derived only 49% were matched to disease and clinical context. CONCLUSION While CEAs are increasingly common in RT, reporting and methodologic rigor must improve. Greater use of published guidelines will improve data quality for decision makers.

Abstract
PURPOSE/OBJECTIVE(S) Continuing professional development (CPD) involves continuing medical education (CME), as well as educational activities to enhance research, teaching and leadership skills. Although CPD has been well explored in other specialties, the literature pertaining to radiation oncology is lacking. We sought to evaluate current CPD practices of radiation oncologists (RO) and identify unmet needs and barriers. MATERIALS/METHODS An online survey on CPD was developed in English and French, approved by ethics board, and emailed to all RO departments across Canada. Respondents' current practices, preferences, barriers, and needs were explored across the CPD domains of CME, research, teaching and administrative skills. RESULTS One-hundred twenty-four radiation oncologists completed the survey with representation across all listed disease sites and provinces. Respondents had an average 13.6 years of experience as staff (6 months to 38 years) and 96% were affiliated with a university. ROs indicated the most helpful resources for CME were reading journal articles (27%), attending tumor boards (25%), conferences (19%), informal discussion with colleagues (11%), free online websites (e.g., NCCN) (4%) and Twitter (3.5%). Lack of time was unanimously regarded as a barrier for CME. Other barriers included growing clinical workloads, expanding literature, and a lack of renumeration for CME. The mean score was 3.5/5, between "neutral" and "satisfied" for "satisfaction that CME needs are met" on a 5-point Likert scale. Seventy-six percent of respondents are currently engaged in research, with 46% involved as a research supervisor. However, only 35% had protected time for research (ranging from 10-80% FTE). Time (89%), funding (63%) and human resources (63%) were cited as barriers. Respondents wanted to improve skills in statistical analysis, clinical trial design and grant writing. Most researchers (78%) were comfortable with quantitative methodologies. Conversely, only 35% were comfortable with qualitative methods. Nearly all respondents (98%) were involved with clinical teaching. While the majority of respondents were satisfied with their teaching ability, many wanted to improve skills in coaching, providing feedback and delivering lectures. The preferred learning formats for improving these skills were either workshops at conferences or online. Half of the respondents are currently in an administrative/leadership role, and of those that are not, only 30% were interested in pursuing future leadership positions. The main barriers cited were time and the experience required. CONCLUSION Overall satisfaction scores for current CME practices were mediocre amongst Canadian radiation oncologists - a group that is mostly in university-affiliated/academic practices with 98% involved in clinical teaching. There are notable barriers and unmet needs in research, teaching and administration - highlighting potential areas for future CPD initiatives in radiation oncology.

Abstract
Considering equity in early childhood development (ECD) is important to ensure healthy development for every child. Equity-informative cost-effectiveness analysis can further guide decision makers to maximize outcomes with limited resources while promoting equity. This cost-effectiveness study aimed to examine the equity impacts of a multicomponent ECD intervention in rural Vietnam. We estimated the cost-effectiveness of the intervention with a 30-month time horizon from the service provider and household perspectives with equity considerations. Data were from a cluster-randomized controlled trial comparing the intervention with the local standard of care. The incremental cost-effectiveness ratios (ICERs) per child cognitive development score gained were estimated by household wealth quintile and maternal education level, adjusted for cluster effects and baseline characteristics such as maternal parity and age. A 3% discount rate was applied to costs, and non-parametric cluster bootstrapping was used to examine uncertainty around ICERs. Children in the intervention had higher cognitive development scores than those in the control arm across all subgroups. Based on intervention recurrent cost, the ICER per cognitive development score gained was lower in children from the poorest quintile (-US$6) compared to those from the richest quintile (US$16). Similarly, the ICER per cognitive development score gained was lower in children whose mothers had the lowest education level (-US$0.02) than those with mothers who had the highest education level (US$7). Even though our findings should be interpreted with caution due to the insufficient study power, the findings suggest that the intervention could promote equity while improving child cognitive development with greater cost-effectiveness in disadvantaged groups.

Abstract
BACKGROUND Economic evaluations are critical to ensure effective resource use to implement and scale up child development interventions. This study aimed to estimate the cost-effectiveness of a multicomponent early childhood development intervention in rural Viet Nam. METHODS We did a cost-effectiveness study alongside a cluster-randomised trial with a 30-month time horizon. The study included 669 mothers from 42 communes in the intervention group, and 576 mothers from 42 communes in the control group. Mothers in the intervention group attended Learning Clubs sessions from mid-pregnancy to 12 months after delivery. The primary outcomes were child cognitive, language, motor, and social-emotional development at age 2 years. In this analysis, we estimated the incremental cost-effectiveness ratios (ICERs) of the intervention compared with the usual standard of care from the service provider and household perspectives. We used non-parametric bootstrapping to examine uncertainty, and applied a 3% discount rate. FINDINGS The total intervention cost was US$169 898 (start-up cost $133 692 and recurrent cost $36 206). The recurrent cost per child was $58 (1 341 741 Vietnamese dong). Considering the recurrent cost alone, the base-case ICER was $14 and mean ICER of 1000 bootstrap samples was $14 (95% CI -0·48 to 30) per cognitive development score gained with a 3% discount rate to costs. The ICER per language and motor development score gained was $22 and $20, respectively, with a 3% discount rate to costs. INTERPRETATION The intervention was cost-effective: the ICER per child cognitive development score gained was 0·5% of Viet Nam's gross domestic product per capita, alongside other benefits in language and motor development. This finding supports the scaling up of this intervention in similar socioeconomic settings. FUNDING Australian National Health and Medical Research Council and Grand Challenges Canada.

Abstract
Young migrant women workers frequently experience disparities in accessing health services, including sexual and reproductive health (SRH) services, especially in urban settings. This study assesses the barriers and utilization of SRH services and explores factors associated with the utilization of these services among young female migrant workers working in the industrial zone (IZ) in Vietnam. A cross-sectional survey was conducted among 1061 young women migrant workers working in an IZ in Hanoi, Vietnam. Multivariable logistic regression analysis was used to identify factors associated with utilization of SRH services. Nearly 35% of the participants reported using SRH services at least once since working in the IZ. Additionally, around 78% of the participants reported using a contraceptive method during their last sexual encounter. The study also found that older participants (25-29 years old) were nearly two times more likely to use SRH services than younger participants (18-24 years old) (OR = 1.91, 95% CI: 1.19-3.06). Married participants had nearly six times higher odds of using SRH services compared to single participants (OR = 5.98, 95% CI: 3.71-9.63), and participants with higher incomes were more likely to use SRH services (OR = 1.02, 95% CI: 1.01-1.04). The most commonly reported barriers to access SRH services were inconvenient hours of service operation (26.2%), followed by long distance from the service location (9.2%) and high service cost (5.2%). This study found a low level of SRH service utilization and identified several barriers to accessing these services among the study participants. The study findings provide important evidence insights for policymakers and program managers to develop and implement policies that help reduce barriers and enhance the provision of SRH services tailored to the needs of IZ married and unmarried women migrant workers in the IZ in rapidly developing and urbanizing countries like Vietnam and other low- and middle-income countries with similar contexts.

Abstract
Bempegaldesleukin (BEMPEG), a CD122-preferential IL2 pathway agonist, has been shown to induce proliferation and activation of NK cells. NK activation is dependent on the balance of inhibitory and excitatory signals transmitted by NK receptors, including Fc-gamma receptors (FCγRs) and killer immunoglobulin-like receptors (KIRs) along with their KIR-ligands. The repertoire of KIRs/KIR-ligands an individual inherits and the single-nucleotide polymorphisms (SNPs) of FCγRs can influence NK function and affect responses to immunotherapies. In this retrospective analysis of the single-arm PIVOT-02 trial, 200 patients with advanced solid tumors were genotyped for KIR/KIR-ligand gene status and FCγR SNP status and evaluated for associations with clinical outcome. Patients with inhibitory KIR2DL2 and its ligand (HLA-C1) observed significantly greater tumor shrinkage (TS, median change -13.0 vs. 0%) and increased PFS (5.5 vs. 3.3 months) and a trend toward improved OR (31.2 vs. 19.5%) compared to patients with the complementary genotype. Furthermore, patients with KIR2DL2 and its ligand together with inhibitory KIR3DL1 and its ligand (HLA-Bw4) had improved OR (36.5 vs. 19.6%), greater TS (median change -16.1 vs. 0%), and a trend toward prolonged PFS (8.4 vs. 3.6 months) as compared to patients with the complementary genotype. FCγR polymorphisms did not influence OR/PFS/TS.These data show that clinical response to BEMPEG plus nivolumab treatment in the PIVOT-02 trial may be associated with the repertoire of KIR/KIR-ligands an individual inherits. Further investigation and validation of these results may enable KIR/KIR-ligand genotyping to be utilized prospectively for identifying patients likely to benefit from certain cancer immunotherapy regimens.

Frayne J, Ellies R, Nguyen T. Experiences of decision making about psychotropic medication during pregnancy and breastfeeding in women living with severe mental illness: a qualitative study.

Abstract
PURPOSE The aim of this study was to explore the experiences of women living with severe mental illnesses making decisions about psychotropic medication use in pregnancy and breastfeeding, and what helped or hindered the decision-making process. METHODS We report on a qualitative study from 12 women who attended the pregnancy service between May 2018 and June 2019. Interviews occurred at 4-6 weeks postpartum on women with severe mental illnesses, which was nested within a larger mixed-methods study. RESULTS Three main themes were elicited from the participants' transcriptions and included (i) the decision-making process with subthemes of shared decision-making, consistency and complete care, collaboration and clear communication, and challenges of managing medication; (ii) how information is given, with subthemes of information delivery and communication breakdown; and (iii) breastfeeding dilemmas with subthemes of lithium and breastfeeding choice and autonomy regarding breastfeeding on medication. CONCLUSION Findings offer understanding of patients' experiences in the decision-making and use of psychotropic medication during pregnancy and breastfeeding. Women living with severe mental illnesses, such as bipolar and psychosis, face difficult medication decisions due to uncertainty around use in pregnancy, potentially causing conflict with their dual role as both persons with a diagnosed mental illness but also new mothers. The clinician needs to provide comprehensible and concise information, giving space for a woman's voice to be heard to guide them from a position of hesitancy to one of assurance. Collaboration within a multidisciplinary team and external care providers combined with consistency of care assists this process.

Abstract
As a fundamental aspect of normal cell signaling and disease states, there is great interest in determining alternative splicing (AS) changes in physiologic, pathologic, and pharmacologic settings. High throughput RNA sequencing and specialized software to detect AS has greatly enhanced our ability to determine transcriptome-wide splicing changes. Despite the richness of this data, deriving meaning from sometimes thousands of AS events is a substantial bottleneck for most investigators. We present SpliceTools, a suite of data processing modules that arms investigators with the ability to quickly produce summary statistics, mechanistic insights, and functional significance of AS changes through command line or through an online user interface. Utilizing RNA-seq datasets for 186 RNA binding protein knockdowns, nonsense mediated RNA decay inhibition, and pharmacologic splicing inhibition, we illustrate the utility of SpliceTools to distinguish splicing disruption from regulated transcript isoform changes, we show the broad transcriptome footprint of the pharmacologic splicing inhibitor, indisulam, we illustrate the utility in uncovering mechanistic underpinnings of splicing inhibition, we identify predicted neo-epitopes in pharmacologic splicing inhibition, and we show the impact of splicing alterations induced by indisulam on cell cycle progression. Together, SpliceTools puts rapid and easy downstream analysis at the fingertips of any investigator studying AS.

Abstract
The purpose of this study was to understand the factors behind university teachers' ability to implement instructional changes during the COVID-19 pandemic. An online questionnaire comprised of open-ended and Likert-scale questions was administered to teachers at a Finnish university in April 2020. The sample consisted of 378 university teachers who were categorised into four groups based on their digital innovativeness and the extent to which they implemented changes to adapt their teaching practices to COVID-19 restrictions: Avoider Survival Adapters, Avoider Ambitious Adapters, Embracer Survival Adapters, and Embracer Ambitious Adapters. We examined the association between the teacher groups and their learning patterns and background characteristics. The findings showed that Embracer Ambitious Adapters have significantly more meaning-oriented and application-oriented learning patterns than Embracer Survival Adapters, though Avoider Survival Adapters have more problematic learning patterns. Furthermore, the results indicated that pedagogical training and having more teaching experience helped innovative teachers embrace more changes in their teaching practices during the COVID-19 pandemic. In terms of discipline, the results showed that teachers working in hard disciplines (e.g., physics) were more likely to belong to the Embracer Survival Adapters group, while teachers working in soft disciplines (e.g., history) were more likely to belong to the Embracer Ambitious Adapters group. Possible interpretations of these findings and perspectives for further research are discussed.

Abstract
Abstract
Leukocyte telomere length (LTL) is known as a heritable marker of cellular aging and is a risk factor for several chronic diseases. LTL distribution and association studies are essential in providing insights into telomere homeostasis, its relationship with different metabolic traits, and age-related conditions. Such studies have been underperformed in Asian population groups. Here we estimated LTL using whole-genome sequencing data in 8,045 Singaporean samples across three major ethnic groups - Chinese, Indian, and Malay divided into six cohorts: GUSTO, HELIOS, MEC, PRISM, SEED, and TTSH. LTLs were measured using TelSeq, with normalized LTL as phenotype in subsequent analyses. We demonstrated that average LTL was robustly longer in the childhood cohort (GUSTO) compared to the adult cohorts (P<1.19 × 10−195). We observed ethnicity differences in LTL where adult Singaporean Chinese samples had the longest LTL (5.08kb) as compared to Malay (4.87kb) and Indian (4.65kb) samples in our datasets (P<4.98 × 10−12). Our genetic association analyses replicated multiple variants previously reported to be associated with LTL (binomial P<0.00001) in Asian population groups, providing added confidence in the methodologies used. At the same time, we identified a novel East-Asian-specific novel variant beyond genome-wide association levels (meta P=2.05 × 10−08) at the COL28A1/MIOS gene loci to be associated with LTL in our study. Individual analysis of the GUSTO childhood dataset highlighted a second novel genome-wide hit at RAD17 gene locus to be associated with LTL in our study and indicated that the previously reported variant at the TINF2 locus may have significantly opposing effects (compared to adults) during early developmental stages. Gene-level burden analysis for rare variants (MAF <5%) in adult Chinese cohorts revealed potential cancer association with RET gene (SKAT, P=5.22 × 10−03) and MLH1 gene (SKAT, P=0.037), as well as telomere biology condition association with RECQL4 gene (CMC, P=0.0399, and VT, P=0.0379). Our findings have broadened the understanding of LTL distribution and the underlying associated genetic characteristics in both childhood and adult Singaporean populations.

Abstract
Associations between human genetic variation and clinical phenotypes have become a foundation of biomedical research. Most repositories of these data seek to be disease-agnostic and therefore lack disease-focused views. The Type 2 Diabetes Knowledge Portal (T2DKP) is a public resource of genetic datasets and genomic annotations dedicated to type 2 diabetes (T2D) and related traits. Here, we seek to make the T2DKP more accessible to prospective users and more useful to existing users. First, we evaluate the T2DKP's comprehensiveness by comparing its datasets with those of other repositories. Second, we describe how researchers unfamiliar with human genetic data can begin using and correctly interpreting them via the T2DKP. Third, we describe how existing users can extend their current workflows to use the full suite of tools offered by the T2DKP. We finally discuss the lessons offered by the T2DKP toward the goal of democratizing access to complex disease genetic results.

Abstract
AIMS Most children requiring radiotherapy receive external beam treatment and few have tumours suitable for brachytherapy. No paediatric radiotherapy centre will treat enough patients from its own normal catchment population for expertise in brachytherapy to be developed and sustained. Following discussion and agreement in the national paediatric radiotherapy group, a service for paediatric brachytherapy in the UK has been developed. We report the process that has evolved over more than 10 years, with survival and functional outcome results. MATERIALS AND METHODS Since 2009, potential patients have been referred to the central paediatric oncology multidisciplinary team meeting, where imaging, pathology and treatment options are discussed. Since 2013, the National Soft Tissue Sarcoma Advisory Panel has also reviewed most patients, with the principal aim of advising on the most suitable primary tumour management for complex patients. Clinical assessment and examination under anaesthetic with biopsies may be undertaken to confirm the appropriateness of brachytherapy, either alone or following conservative surgery. Fractionated high dose rate brachytherapy was delivered to a computed tomography planned volume after implantation of catheters under ultrasound imaging guidance. Since 2019, follow-up has been in a dedicated multidisciplinary clinic. RESULTS From 2009 to 2021 inclusive, 35 patients (16 female, 19 male, aged 8 months to 17 years 6 months) have been treated. Histology was soft-tissue sarcoma in 33 patients and carcinoma in two. The treated site was pelvic in 31 patients and head and neck in four. With a median follow-up of 5 years, the local control and overall survival rates are 100%. Complications have been few, and functional outcome is good. CONCLUSION Brachytherapy is effective for selected paediatric patients, resulting in excellent tumour control and good functional results. It is feasible to deliver paediatric brachytherapy at a single centre within a national referral service.

Abstract
Real-time target position verification during pancreas stereotactic body radiation therapy (SBRT) is important for the detection of unplanned tumour motions. Fast and accurate fiducial marker segmentation is a Requirement of real-time marker-based verification. Deep learning (DL) segmentation techniques are ideal because they don't require additional learning imaging or prior marker information (e.g., shape, orientation). In this study, we evaluated three DL frameworks for marker tracking applied to pancreatic cancer patient data. The DL frameworks evaluated were (1) a convolutional neural network (CNN) classifier with sliding window, (2) a pretrained you-only-look-once (YOLO) version-4 architecture, and (3) a hybrid CNN-YOLO. Intrafraction kV images collected during pancreas SBRT treatments were used as training data (44 fractions, 2017 frames). All patients had 1-4 implanted fiducial markers. Each model was evaluated on unseen kV images (42 fractions, 2517 frames). The ground truth was calculated from manual segmentation and triangulation of markers in orthogonal paired kV/MV images. The sensitivity, specificity, and area under the precision-recall curve (AUC) were calculated. In addition, the mean-absolute-error (MAE), root-mean-square-error (RMSE) and standard-error-of-mean (SEM) were calculated for the centroid of the markers predicted by the models, relative to the ground truth. The sensitivity and specificity of the CNN model were 99.41% and 99.69%, respectively. The AUC was 0.9998. The average precision of the YOLO model for different values of recall was 96.49%. The MAE of the three models in the left-right, superior-inferior, and anterior-posterior directions were under 0.88 ± 0.11 mm, and the RMSE were under 1.09 ± 0.12 mm. The detection times per frame on a GPU were 48.3, 22.9, and 17.1 milliseconds for the CNN, YOLO, and CNN-YOLO, respectively. The results demonstrate submillimeter accuracy of marker position predicted by DL models compared to the ground truth. The marker detection time was fast enough to meet the requirements for real-time application.

Abstract
OBJECTIVES This study aimed to assess changes in paid maternity leave before and after New York's (NY) Paid Family Leave (PFL) law went into effect (1/1/2018) and changes in disparities by maternal characteristics. METHODS We used specific data collected on maternity leaves by women who gave birth in 2016-2018 in NY State (outside NY City) participating in the Pregnancy Risk Assessment Monitoring System survey. Multiple logistic regressions were conducted to evaluate the effect of the PFL law on prevalence of paid leave taken by women after childbirth. RESULTS After NY's PFL law went into effect, there was a 26% relative increase in women taking paid leave after childbirth. Use of paid leave after childbirth increased among all racial and ethnic groups. The increases were greater among Black non-Hispanic or other race non-Hispanic women, compared to white non-Hispanic women, suggesting that NY's law was associated with more equitable use of paid leave following childbirth. CONCLUSIONS FOR PRACTICE Wider implementation and greater utilization of paid maternity leave policies would promote health equity and help reduce racial/ethnic disparities in maternal and child health outcomes.

Abstract
BACKGROUND AND PURPOSE There is active research involving the radiographic appearance of the skull base following reconstruction. The purpose of this study was to describe the radiographic appearance of the vascularized pedicle nasoseptal flap after endoscopic skull base surgery across time. MATERIALS AND METHODS We performed chart and imaging review of all patients with intraoperative nasoseptal flap placement during endoscopic skull base surgery at a tertiary academic skull base surgery program between July 2018 and March 2021. All patients underwent immediate and delayed (>3 months) postoperative MR imaging. Primary outcome variables included flap and pedicle enhancement, flap thickness, and flap adherence to the skull base. RESULTS Sixty-eight patients were included. Flap (P = .003) enhancement significantly increased with time. Mean nasoseptal flap thickness on immediate and delayed postoperative scans was 3.8 and 3.9 mm, respectively (P = .181). The nasoseptal flap adhered entirely to the skull base in 37 (54.4%) and 67 (98.5%) patients on immediate and delayed imaging, respectively (P < .001). CONCLUSIONS Our findings demonstrate heterogeneity of the nasoseptal flap appearance after skull base reconstruction. While it is important for surgeons and radiologists to evaluate variations in flap appearance, the absence of enhancement and lack of adherence to the skull base on immediate postoperative imaging do not appear to predict reconstructive success and healing, with many flaps "self-adjusting" with time.

Abstract
Angiotensin-converting enzyme 2 (ACE2), part of the renin-angiotensin system (RAS), serves as an entry point for SARS-CoV-2, leading to viral proliferation in permissive cell types. Using mouse lines in which the Ace2 locus has been humanized by syntenic replacement, we show that regulation of basal and interferon induced ACE2 expression, relative expression levels of different ACE2 transcripts, and sexual dimorphism in ACE2 expression are unique to each species, differ between tissues, and are determined by both intragenic and upstream promoter elements. Our results indicate that the higher levels of expression of ACE2 observed in the lungs of mice relative to humans may reflect the fact that the mouse promoter drives expression of ACE2 in populous airway club cells while the human promoter drives expression in alveolar type 2 (AT2) cells. In contrast to transgenic mice in which human ACE2 is expressed in ciliated cells under the control of the human FOXJ1 promoter, mice expressing ACE2 in club cells under the control of the endogenous Ace2 promoter show a robust immune response after infection with SARS-CoV-2, leading to rapid clearance of the virus. This supports a model in which differential expression of ACE2 determines which cell types in the lung are infected, and this in turn modulates the host response and outcome of COVID-19.

Background
Patients with chronic kidney disease, especially end-stage renal disease, exhibit a very high cardiovascular risk. In Vietnam, chronic kidney disease and cardiovascular disease (CVD) are very common in older people. However, there is limited studies on the complexity of CVD and other geriatric syndromes in older patients with end-stage renal disease and chronic dialysis.
Purpose
In this study in older patients with end-stage renal disease and chronic dialysis, we aim to: (1) Examine the prevalence of CVD and its impact on hospitalization, and (2) Compare the burden of common geriatric syndromes in patients with and without CVD.
Methods
This is a prospective, observational, multi-centre study conducted at two dialysis units of two major hospitals in Vietnam. Consecutive patients aged 60 years or older who were diagnosed with end-stage renal disease and on chronic dialysis were recruited from November 2020 to June 2021. CVD was defined as having one of these conditions: heart failure, ischemic heart disease, and stroke. Participants were assessed for these common geriatric conditions: frailty (defined as a Clinical Frailty Scale total score ≥5), malnutrition (defined as a total score ≤7 from the Mini Nutritional Assessment Short Form), impairment in activities of daily living (defined as ADL score <6), impairment in instrumental activities of daily living (defined as IADL score <8), high risk of falls (assessed by the STEADI questionnaire), and polypharmacy (defined as the concurrent use of ≥5 medications). Participants were followed for 6 months after discharge. Multivariable logistic regression analysis was applied to examine the impact of CVD on 6-month hospitalization, adjusting for age, sex, and the geriatric conditions. Results were presented as odds ratios (ORs) and 95% confidence intervals (CIs).
Results
There were 175 participants (mean age 72.4 ± 8.5, 58.9% female). CVD was present in 80% of the participants (ischemic heart disease: 49.7%, heart failure: 60.0%, stroke 25.7%). Participants with CVD had significantly higher prevalence of geriatric syndromes compared to those without CVD (Table 1). During 6-month follow-up, 48.6% of the participants had at least one hospitalization. In multivariable logistic regression model, the presence of CVD increased the risk of hospitalization (adjusted OR 4.70, 95%CI 1.72 – 12.85), allowing for age, sex, frailty, ADL impairment, IADL impairment, fall risk, malnutrition, polypharmacy (Table 2).
Conclusion
In this study, there was a very high prevalence of CVD in older patients with end-stage renal disease and chronic dialysis. Participants with CVD had higher burden of geriatric syndromes and their risk of 6-month hospitalization increased by approximately 5 times.

Background
The prevalence of coronary heart disease increases with age and older people accounted for a large proportion of patients presenting with coronary heart disease. Advancement in percutaneous coronary intervention (PCI) has contributed to reduced mortality in patients with coronary artery disease. However, coronary angiography and percutaneous intervention have also increased the risk of developing contrast induced nephropathy (CIN), especially in older patients. More than ten risk assessment tools have been developed to predict CIN. Among these, the Mehran risk score has been the most commonly used in Vietnam. In recent years, new simple risk prediction models have been proposed, including the contrast volume-to-glomerular filtration rate ratio (CV/GFR ratio). The CV/GFR ratio is calculated as the ratio of contrast medium quantity to glomerular filtration rate.
Purpose
The aim of this study was to (1) examine the incidence of CIN in a cohort of older patients undergoing coronary angiography and/or PCI at a tertiary hospital in Vietnam, (2) compare the validity of the CV/GFR ratio and the Mehran score in predicting CIN, and (3) to identify optimal cut-off points of these scales by which can help identify older patients with high risk of developing CIN in this population.
Methods
A prospective observational study was conducted in patients aged ≥ 60 years at a tertiary hospital in Vietnam from September 2019 to May 2020. CIN was defined as 25% increase in serum creatinine from baseline or 0.5mg/dL absolute increase in serum creatinine occurring within 48 hours post IV contrast administration. The CV/GFR ratio and the Mehran score were applied for predicting risk of CIN. Previous studies suggest Mehran score >5 or CV/GFR ratio >3.7 as a predictor of an early abnormal increase in serum creatinine after PCI. Receiver Operator Characteristic (ROC) was applied to evaluate area under the curve (AUC) of the CV/GFR ratio and Mehran score in predicting CIN, and the sensitivity, specificity for common cut-off points that were suggested in previous studies.
Results
A total of 170 participants were included in this study. They had a mean age of 70 years, 33.1% were women. The incidence of CIN was 9.4%. Participants with CIN had higher prevalence of chronic kidney disease, heart failure and anaemia at admission. The AUC of the CV/GFR ratio against CIN was 0.79 (95%CI 0.65-0.92), and of the Mehran score against CIN was 0.65 (95%CI 0.51-0.82) (Figure 1). The sensitivity and specificity for common cut-off points of the CV/GFR ratio and Mehran score are presented in Figure 2.
Conclusions
Our study found that CIN was common in older patients after PCI. Both CV/GFR ratio and Mehran score had good diagnostic value for predicting CIN in the study participants.

Abstract
IMPORTANCE Patients with chronic pain often receive long-term opioid therapy (LOT), which places them at risk of opioid use disorder and overdose. This presents the need for alternative or companion treatments; however, few studies on the association of medical cannabis (MC) with reducing opioid dosages exist. OBJECTIVE To assess changes in opioid dosages among patients receiving MC for longer duration compared with shorter duration. DESIGN, SETTING, AND PARTICIPANTS This cohort study of New York State Prescription Monitoring Program data from 2017 to 2019 included patients receiving MC for chronic pain while also receiving opioid treatment. Of these, patients receiving LOT prior to receiving MC were selected. Individuals were studied for 8 months after starting MC. Data were analyzed from November 2021 to February 2022. EXPOSURES Selected patients were divided into 2 groups based on the duration of receiving MC: the nonexposure group received MC for 30 days or fewer, and the exposure group received MC for more than 30 days. MAIN OUTCOMES AND MEASURES The main outcome was opioid dosage, measured by mean daily morphine milligram equivalent (MME). Analyses were conducted for 3 strata by opioid dosage prior to receiving MC: MME less than 50, MME of 50 to less than 90, and MME of 90 or greater. RESULTS A total of 8165 patients were included, with 4041 (median [IQR] age, 57 [47-65] years; 2376 [58.8%] female) in the exposure group and 4124 (median [IQR] age, 54 (44-62) years; 2370 [57.5%] female) in the nonexposure group. Median (IQR) baseline MMEs for the exposure vs nonexposure groups were 30.0 (20.0-40.0) vs 30.0 (20.0-40.0) in the lowest stratum, 60.0 (60.0-70.0) vs 60.0 (60.0-90.0) in the middle stratum, and 150.0 (100.0-216.2) vs 135.0 (100.0-218.0) in the highest stratum. During follow-up, significantly greater reductions in opioid dosage were observed among the exposure group. A dose-response association of patients' opioid dosage at baseline was observed with the differences in the monthly MME reductions between exposure and nonexposure groups, with a difference of -1.52 (95% CI, -1.67 to -1.37) MME for the lowest stratum, -3.24 (95% CI, -3.61 to -2.87) MME for the middle stratum, and -9.33 (95% CI, -9.89 to -8.77) MME for the highest stratum. The daily MME for the last month of the follow-up period among patients receiving longer MC was reduced by 48% in the lowest stratum, 47% in the middle stratum, and 51% in the highest stratum compared with the baseline dosages. Among individuals in the nonexposure group, daily MME was reduced by only 4% in the lowest stratum, 9% in the middle stratum, and 14% in the highest stratum. CONCLUSIONS AND RELEVANCE In this cohort study of patients receiving LOT, receiving MC for a longer duration was associated with reductions in opioid dosages, which may lower their risk of opioid-related morbidity and mortality.

Abstract
Abstract
Background
Antimicrobial resistance (AMR) is a global challenge and influenced by several factors including antibiotic overprescribing. Antibiotics are frequently prescribed in Vietnam, especially in pediatric acute respiratory illnesses (ARIs). Understanding prescribing practices for pediatric ARIs is important to help identify areas for improved practices to prevent overprescribing and AMR.
Methods
We performed a retrospective review of pediatric patients aged 0-15 years with an ARI diagnosis based on ICD-10 codes from January 1-December 31, 2019 in 112 primary care centers in Northern Vietnam. Variables collected included age, sex, district, antibiotic prescribed, World Health Organization access, watch, reserve classification (WHO AWaRe), symptomatic agents prescribed, and signs and symptoms. Data was analyzed using descriptive statistical analysis.
Results
A total of 35,679 encounters were reviewed. Of all encounters, 34,018 (95.3%) received antibiotics, and 1,650 (4.9%) of these received >1 antibiotic (Table 1). According to WHO AWaRe classification, 19.3% of children 0 to < 5 years received a watch antibiotic compared to 10.4% in those 5 to15 years. The most frequent diagnosis was acute pharyngitis (21,270 encounters, 59.6%) and 20,496 (96.4%) of those encounters received antibiotics. Common signs and symptoms reported included cough (76.3%), fever (40.9%), and erythematous pharynx (33.1%). Though acute pharyngitis was the most common diagnosis, only 168 (0.5%) and 59 (0.2%) of encounters described lymphadenopathy and exudate, respectively.
Conclusion
Antibiotics are frequently prescribed for pediatric ARIs in Northern Vietnam. Most antibiotics prescribed were WHO AWaRe access antibiotics; however, 14% were watch antibiotics or not recommended. Though acute pharyngitis was the most common diagnosis, only a few of the encounters reported signs or symptoms that would be more suggestive of acute bacterial pharyngitis warranting antibiotics. Further investigation of the appropriateness of antibiotic prescriptions are needed to help identify targeted areas of improvement in prescribing practices and help decrease the burden of AMR.

Abstract
OBJECTIVE To test whether introduction of New York Paid Family Leave (NY PFL) in 2018 is associated with the timeliness of immunizations among infants whose mothers reside in NY in one of the 57 counties outside of New York City (NYC). METHODS We use difference-in-difference methods, comparing immunization outcomes before and after NY PFL went into effect among infants born to mothers who were employed during pregnancy, and thus likely to be affected by NY PFL, vs. mothers who were not employed during pregnancy and thus unlikely to be affected. Data come from two administrative sources: (1) NYS Vital Statistics birth data; and (2) the NYS Immunization Information System (NYSIIS). RESULTS Our findings suggest that NY PFL is associated with small increases in the probability that firstborn infants have had all immunizations on time at the ages of two and four months. We do not find statistically significant effects of NY PFL on immunization outcomes among higher birth order children. CONCLUSIONS Our findings suggest that NY PFL led to small improvements in the timeliness of early immunizations among firstborn infants.

Abstract
In the interest of public health, it is important to nudge children toward healthier food choices (e.g., beverages with less added sugar). We conducted a field experiment in a peri-urban region in Vietnam to evaluate the effects of information and cognitive dissonance on the food choices of children. Our sample consisted of more than 1200 primary school children, randomly assigned into three groups: control, health information, and health information plus hypocrisy inducement. The third group was intended to raise cognitive dissonance by illustrating the gap between what people know they should do (socially desired behaviors) and what they actually do (transgressions). The results indicate that health information increased the likelihood of selecting milk with less sugar by around 30 %, as compared to the control group. Hypocrisy inducement did not make any additional contribution to healthier food choices. The treatment effects declined when there was a delay between the treatment and the behavioral choice. We discuss the practical implications of our findings for short-term intervention field studies.

Abstract
Abstract
CDK7 has been identified as a potential drug target for glioblastoma (GBM), a highly lethal primary brain tumor. However, resistance to therapy develops quickly, which may be facilitated by drug-induced reprogramming of metabolism. By combination of a transcriptome and metabolite screening analyses followed by carbon tracing (U-13C-Glucose, U-13C-Glutamine and U-13C-Palmitic acid) and extracellular flux analysis we demonstrated that both genetic and pharmacological (YKL-5-124 and THZ1) CDK7 inhibition elicited substantial metabolic reprogramming. Specifically, CDK7i elicited an increase of oxygen consumption rate fueled by enhanced fatty acid oxidation (FAO) manifested by enhanced labeling of citric acid cycle intermediates from palmitic acid. Consistently, the combination treatment of CDK7i inhibitors with blockers of FAO (etomoxir) or cellular respiration (gamitrinib) exerted substantial synergistic growth inhibition in patient derived xenograft as well as neurosphere GBM cultures, which was mainly driven by a collapse of oxidative energy metabolism. In turn, exogenous administration of adenosine triphosphate partially rescued from the cell death induced by the combination treatment. Moreover, the combination treatment activated intrinsic apoptosis through a reduction of both Mcl-1 and Bcl-xL as demonstrated by rescue experiments. Finally, the combined administration of YKL-5-124 and etomoxir extended overall in an orthotopic patient-derived xenograft model of GBM. In summary, these data support that simultaneous targeting of CDK7 and FAO might be a potential novel therapy against GBM.
