Real-life management of psoriasis with biological agents during pregnancy.

BACKGROUND: French guidelines recommend stopping biologic treatment of psoriasis between 3 and 24 weeks before conception in accordance with the relevant Summary of Product Characteristics (SmPC). The aim of this study was to evaluate the real-life practice of dermatologists in the management of pregnant women with psoriasis previously treated with biologic agents. We wished to assess the level of practitioner adherence to the relevant SmPCs. MATERIAL AND METHODS: We conducted a study in collaboration with GRPso and Resopso. A computerized questionnaire was completed by the practitioners. We performed descriptive statistics and studied the profile of the practitioners, their level of confidence with continuation of biological agents during pregnancy, and their reported practices on the use of biological agents in pregnancy. Statistical analyses were performed using XLSTAT. A p-value of less than 0.05 was considered significant. RESULTS: A total of 63 dermatologists (women: 71%; mean age 43.8 years) participated in this study, the majority of whom were hospital-based (87%). Recommendations were followed by 36.5% of practitioners, while 44% reported discontinuing biologic agents on diagnosis of pregnancy, and 20.5% reported using these agents during pregnancy. Among dermatologists with more than ten years of experience, 19% reported following the SmPC. Among dermatologists with a patient base >200 (patients treated with biologic agents for psoriasis), 19% reported following the SmPC compared to 54% of practitioners with less than 50 patients. The mean age of dermatologists following the SmPC was 41 years vs. 47 years for those not following the SmPC. DISCUSSION: The majority of practitioners do not follow recommendations on discontinuation of biologic agents before the planning of pregnancy by patients.

TREX1 Inactivation Unleashes Cancer Cell STING-Interferon Signaling and Promotes Antitumor Immunity.

A substantial fraction of cancers evade immune detection by silencing Stimulator of Interferon Genes (STING)-Interferon (IFN) signaling. Therapeutic reactivation of this program via STING agonists, epigenetic, or DNA-damaging therapies can restore antitumor immunity in multiple preclinical models. Here we show that adaptive induction of three prime exonuclease 1 (TREX1) restrains STING-dependent nucleic acid sensing in cancer cells via its catalytic function in degrading cytosolic DNA. Cancer cell TREX1 expression is coordinately induced with STING by autocrine IFN and downstream STAT1, preventing signal amplification. TREX1 inactivation in cancer cells thus unleashes STING-IFN signaling, recruiting T and natural killer (NK) cells, sensitizing to NK cell-derived IFNγ, and cooperating with programmed cell death protein 1 blockade in multiple mouse tumor models to enhance immunogenicity. Targeting TREX1 may represent a complementary strategy to induce cytosolic DNA and amplify cancer cell STING-IFN signaling as a means to sensitize tumors to immune checkpoint blockade (ICB) and/or cell therapies. SIGNIFICANCE: STING-IFN signaling in cancer cells promotes tumor cell immunogenicity. Inactivation of the DNA exonuclease TREX1, which is adaptively upregulated to limit pathway activation in cancer cells, recruits immune effector cells and primes NK cell-mediated killing. Targeting TREX1 has substantial therapeutic potential to amplify cancer cell immunogenicity and overcome ICB resistance. This article is featured in Selected Articles from This Issue, p. 695.

Long-term occupational exposures on disability-free survival and mortality in older adults.

BACKGROUND: The impact of long-term occupational exposures on health in older adults is increasingly relevant as populations age. To date, no studies have reported their impact on survival free of disability in older adults. AIMS: We aimed to investigate the association between long-term occupational exposure and disability-free survival (DFS), all-cause mortality and cause-specific mortality in initially healthy older adults. METHODS: We analysed data from 12 215 healthy participants in the ASPirin in Reducing Events in the Elderly (ASPREE) study whose mean age was 75 years. Their work history was collated with the 'ALOHA-plus JEM' (Job Exposure Matrix) to assign occupational exposures. The primary endpoint, DFS, was a composite measure of death, dementia or persistent physical disability. The secondary endpoint, mortality, was classified according to the underlying cause. Cox proportional hazard models were used to calculate hazard ratios and 95% confidence intervals, adjusted for confounders. RESULTS: A total of 1835 individuals reached the DFS endpoint during the median 4.7 years follow-up period. Both ever-high and cumulative exposure to all dusts and all pesticides during a person's working years were associated with reduced DFS. Compared to no exposure, men with high exposure to dusts and pesticides had a reduced DFS. Neither of these exposures were significantly associated with all-cause mortality. Men with high occupational exposure to solvents and women exposed to dusts experienced higher all-cause and cancer-related mortality. CONCLUSIONS: Long-term occupational exposure to all dusts and pesticides was associated with a reduced DFS and increased mortality in community-dwelling healthy older adults.

Low-dose intravenous recombinant tissue plasminogen activator in acute ischemic stroke without large vessel occlusion screened by 3T MRI.

OBJECTIVE: Globally, there are more than six million deaths due to cerebrovascular disease, which is the second leading cause of death. Although the imaging findings of magnetic resonance imaging (MRI) are more accurate than computed tomography for acute ischemic stroke (AIS), it is uncommon in recombinant tissue plasminogen activator (rTPA) treatment. Alteplase is not only strongly recommended treatment for acute ischemic stroke within 4.5 hours, but also decreases the disability and mortality rate. Besides, low-dose rTPA was associated with significant reductions in symptomatic intracerebral hemorrhage (sICH), compared with standard one. However, the benefits of low-dose rTPA for the treatment of AIS without large vessel occlusion (LVO) have not been fully demonstrated. We evaluated whether the low-dose rTPA in AIS without LVO could improve prognosis in patients three months post-treatment. PATIENTS AND METHODS: This was a cross-sectional study on patients with AIS treated within 4.5 hours of symptom onset admitted to Can Tho S.I.S General Hospital between February 2019 and July 2021. The eligibility criteria were patients aged > 18 years treated with low-dose rTPA (0.6 mg/kg) and screened by 3T MRI. Patients with a pre-hospital modified Rankin score (mRS) ≥ 2 points, intracranial hemorrhage, LVO, or ≥ 3 microbleeds on brain MRI were excluded. The primary outcomes were the favorable outcome rate at three months and safety, which were evaluated by the rates of intracranial hemorrhage and mortality at three months. RESULTS: This study enrolled 92 eligible patients between February 2019 and July 2021. Their National Institute of Health Stroke Scale (NIHSS) scores were 7.5 ± 3.7 at admission, 3.3 ± 3.5 at discharge or seven days after discharge, and 2.2 ± 2.8 at three months. Their mRS were 2.9 ± 0.8 at admission, 1.4 ± 1.3 at discharge or seven days after discharge, and 1.1 ± 1.1 at three months. Elevated cardiac enzymes, age ≥ 75 years, and body mass index ≥ 25 were associated with increased poor outcomes at three months. While AIS was more common in men than women, a similar number of men (33.3%) and women had poor mRS. Three patients had complications associated with low-dose rTPA treatment: one (1.1%) had intracranial hemorrhage, one (1.1%) had new infarcts, and one (1.1%) had gastrointestinal bleeding. No deaths occurred within three months. CONCLUSIONS: Our study indicates the efficacy and safety of low-dose rTPA treatment for AIS without LVO within 4.5 hours. Patient selection for rTPA by 3T MRI decreased complications and mortality.

ALK peptide vaccination restores the immunogenicity of ALK-rearranged non-small cell lung cancer.

Anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC) is treated with ALK tyrosine kinase inhibitors (TKIs), but the lack of activity of immune checkpoint inhibitors (ICIs) is poorly understood. Here, we identified immunogenic ALK peptides to show that ICIs induced rejection of ALK+ tumors in the flank but not in the lung. A single-peptide vaccination restored priming of ALK-specific CD8+ T cells, eradicated lung tumors in combination with ALK TKIs and prevented metastatic dissemination of tumors to the brain. The poor response of ALK+ NSCLC to ICIs was due to ineffective CD8+ T cell priming against ALK antigens and is circumvented through specific vaccination. Finally, we identified human ALK peptides displayed by HLA-A*02:01 and HLA-B*07:02 molecules. These peptides were immunogenic in HLA-transgenic mice and were recognized by CD8+ T cells from individuals with NSCLC, paving the way for the development of a clinical vaccine to treat ALK+ NSCLC.

First report of the International Council of Cardiovascular Prevention and Rehabilitation's Registry (ICRR).

OBJECTIVES: Cardiac rehabilitation - programs comprehensively delivering outpatient secondary prevention - is under-available and under-studied in the resource-poor settings where it is needed most. This report summarizes the governance, participating sites, patient characteristics and outcomes, as well as knowledge translation activities during first year of operation of ICCPR's registry, namely the International Cardiac Rehab Registry. METHODS: A pilot study was undertaken with five centers, demonstrating feasibility, satisfaction with the on-boarding processes, as well as data quality. RESULTS: Fourteen centers have been engaged from all regions but Europe; Data have been entered on >1000 patients (18.1% female; mean age = 57.6), of whom 62.4% completed their programs and 19.9% dropped out for work or clinical reasons. Post-program, completers had significantly better work status, functional capacity, medication adherence, physical activity levels, diet, as well as lower tobacco use than non-completers (all p < 0.05). A site Certification program was developed and piloted, with five centers now recognized for their quality, given they met over 70% of the 13 internationally agreed standards based on Registry data and a virtual site assessment. CONCLUSION: Annual assessments have started. Quality improvement activities will soon be underway. We continue to invite new programs, supporting development in resource-poor settings to the benefit of patients served.

Patterns of Care and Outcomes of Rectal Cancer Patients from the Iowa Cancer Registry: Role of Hospital Volume and Tumor Location.

BACKGROUND: Centralization of rectal cancer surgery has been associated with high-quality oncologic care. However, several patient, disease and system-related factors can impact where patients receive care. We hypothesized that patients with low rectal tumors would undergo treatment at high-volume centers and would be more likely to receive guideline-based multidisciplinary treatment. METHODS: Adults who underwent proctectomy for stage II/III rectal cancer were included from the Iowa Cancer Registry and supplemented with tumor location data. Multinomial logistic regression was employed to analyze factors associated with receiving care in high-volume hospital, while logistic regression for those associated with ≥ 12 lymph node yield, pre-operative chemoradiation and sphincter-preserving surgery. RESULTS: Of 414 patients, 38%, 39%, and 22% had low, mid, and high rectal cancers, respectively. Thirty-two percent were > 65 years, 38% female, and 68% had stage III tumors. Older age and rural residence, but not tumor location, were associated with surgical treatment in low-volume hospitals. Higher tumor location, high-volume, and NCI-designated hospitals had higher nodal yield (≥ 12). Hospital-volume was not associated with neoadjuvant chemoradiation rates or circumferential resection margin status. Sphincter-sparing surgery was independently associated with high tumor location, female sex, and stage III cancer, but not hospital volume. CONCLUSIONS: Low tumor location was not associated with care in high-volume hospitals. High-volume and NCI-designated hospitals had higher nodal yields, but not significantly higher neoadjuvant chemoradiation, negative circumferential margin, or sphincter preservation rates. Therefore, providing educational/quality improvement support in lower volume centers may be more pragmatic than attempting to centralize rectal cancer care among high-volume centers.

The germline factor DDX4 contributes to the chemoresistance of small cell lung cancer cells.

Human cancers often re-express germline factors, yet their mechanistic role in oncogenesis and cancer progression remains unknown. Here we demonstrate that DEAD-box helicase 4 (DDX4), a germline factor and RNA helicase conserved in all multicellular organisms, contributes to increased cell motility and cisplatin-mediated drug resistance in small cell lung cancer (SCLC) cells. Proteomic analysis suggests that DDX4 expression upregulates proteins related to DNA repair and immune/inflammatory response. Consistent with these trends in cell lines, DDX4 depletion compromised in vivo tumor development while its overexpression enhanced tumor growth even after cisplatin treatment in nude mice. Further, the relatively higher DDX4 expression in SCLC patients correlates with decreased survival and shows increased expression of immune/inflammatory response markers. Taken together, we propose that DDX4 increases SCLC cell survival, by increasing the DNA damage and immune response pathways, especially under challenging conditions such as cisplatin treatment.

Development of Gestational Age-Based Fetal Brain and Intracranial Volume Reference Norms Using Deep Learning.

BACKGROUND AND PURPOSE: Fetal brain MR imaging interpretations are subjective and require subspecialty expertise. We aimed to develop a deep learning algorithm for automatically measuring intracranial and brain volumes of fetal brain MRIs across gestational ages. MATERIALS AND METHODS: This retrospective study included 246 patients with singleton pregnancies at 19-38 weeks gestation. A 3D U-Net was trained to segment the intracranial contents of 2D fetal brain MRIs in the axial, coronal, and sagittal planes. An additional 3D U-Net was trained to segment the brain from the output of the first model. Models were tested on MRIs of 10 patients (28 planes) via Dice coefficients and volume comparison with manual reference segmentations. Trained U-Nets were applied to 200 additional MRIs to develop normative reference intracranial and brain volumes across gestational ages and then to 9 pathologic fetal brains. RESULTS: Fetal intracranial and brain compartments were automatically segmented in a mean of 6.8 (SD, 1.2) seconds with median Dices score of 0.95 and 0.90, respectively (interquartile ranges, 0.91-0.96/0.89-0.91) on the test set. Correlation with manual volume measurements was high (Pearson r = 0.996, P < .001). Normative samples of intracranial and brain volumes across gestational ages were developed. Eight of 9 pathologic fetal intracranial volumes were automatically predicted to be >2 SDs from this age-specific reference mean. There were no effects of fetal sex, maternal diabetes, or maternal age on intracranial or brain volumes across gestational ages. CONCLUSIONS: Deep learning techniques can quickly and accurately quantify intracranial and brain volumes on clinical fetal brain MRIs and identify abnormal volumes on the basis of a normative reference standard.

Rescue intracranial stenting in acute ischemic stroke: a preliminary Vietnamese study.

OBJECTIVE: In cases of acute ischemic stroke (AIS) caused by intracranial large vessel occlusion, rescue intracranial stenting (RIS) has recently emerged as a treatment option for achieving recanalization when mechanical thrombectomy (MT) fails. However, few studies to date have reported on the beneficial outcomes of RIS. Our goal was to analyze whether RIS use can improve prognosis in patients 3 months post-treatment. PATIENTS AND METHODS: A retrospective analysis was performed on a prospective cohort of patients with AIS treated with RIS at Can Tho S.I.S General Hospital. The study inclusion criteria were evidence of intracranial large vessel occlusion, absence of intracranial hemorrhage (ICH), and severe stenosis or reocclusion after MT. Patients with tandem occlusions, failure to follow up after discharge, or severe or fatal illness concomitant with AIS were excluded from the study. The primary outcome was the "non-poor" prognosis status rate at 3 months after RIS and post-procedural symptomatic ICH (sICH). RESULTS: The post-treatment outcomes of 85 eligible patients who received RIS between August 2019 and May 2021 were assessed. Of the 85 included patients, 82 (96.5%) achieved successful recanalization, and 4 (4.7%) experienced sICH. At 3-months post-treatment, 47 (55.3%) patients had "non-poor" outcomes, whereas 35 (41.2%) had good outcomes. The use of dual antiplatelet therapy was associated with new infarcts (relative risk [RR]: 0.1; 95% confidence interval [CI]: 0.01-0.7) and sICH occurrence (RR: 0.1; 95% CI: 0.01-0.9). CONCLUSIONS: Our study suggests that despite the occurrence of post-procedural sICH in a small proportion of cases, RIS could serve as a useful alternative or additional treatment in the event of MT failure.

MET-Induced CD73 Restrains STING-Mediated Immunogenicity of EGFR-Mutant Lung Cancer.

Immunotherapy has shown limited efficacy in patients with EGFR-mutated lung cancer. Efforts to enhance the immunogenicity of EGFR-mutated lung cancer have been unsuccessful to date. Here, we discover that MET amplification, the most common mechanism of resistance to third-generation EGFR tyrosine kinase inhibitors (TKI), activates tumor cell STING, an emerging determinant of cancer immunogenicity (1). However, STING activation was restrained by ectonucleosidase CD73, which is induced in MET-amplified, EGFR-TKI-resistant cells. Systematic genomic analyses and cell line studies confirmed upregulation of CD73 in MET-amplified and MET-activated lung cancer contexts, which depends on coinduction of FOSL1. Pemetrexed (PEM), which is commonly used following EGFR-TKI treatment failure, was identified as an effective potentiator of STING-dependent TBK1-IRF3-STAT1 signaling in MET-amplified, EGFR-TKI-resistant cells. However, PEM treatment also induced adenosine production, which inhibited T-cell responsiveness. In an allogenic humanized mouse model, CD73 deletion enhanced immunogenicity of MET-amplified, EGFR-TKI-resistant cells, and PEM treatment promoted robust responses regardless of CD73 status. Using a physiologic antigen recognition model, inactivation of CD73 significantly increased antigen-specific CD8+ T-cell immunogenicity following PEM treatment. These data reveal that combined PEM and CD73 inhibition can co-opt tumor cell STING induction in TKI-resistant EGFR-mutated lung cancers and promote immunogenicity. SIGNIFICANCE: MET amplification upregulates CD73 to suppress tumor cell STING induction and T-cell responsiveness in TKI-resistant, EGFR-mutated lung cancer, identifying a strategy to enhance immunogenicity and improve treatment.

MPS1 inhibition primes immunogenicity of KRAS-LKB1 mutant lung cancer.

KRAS-LKB1 (KL) mutant lung cancers silence STING owing to intrinsic mitochondrial dysfunction, resulting in T cell exclusion and resistance to programmed cell death (ligand) 1 (PD-[L]1) blockade. Here we discover that KL cells also minimize intracellular accumulation of 2'3'-cyclic GMP-AMP (2'3'-cGAMP) to further avoid downstream STING and STAT1 activation. An unbiased screen to co-opt this vulnerability reveals that transient MPS1 inhibition (MPS1i) potently re-engages this pathway in KL cells via micronuclei generation. This effect is markedly amplified by epigenetic de-repression of STING and only requires pulse MPS1i treatment, creating a therapeutic window compared with non-dividing cells. A single course of decitabine treatment followed by pulse MPS1i therapy restores T cell infiltration in vivo, enhances anti-PD-1 efficacy, and results in a durable response without evidence of significant toxicity.

Systematic Analysis of Mobile Genetic Elements Mediating ß-Lactamase Gene Amplification in Noncarbapenemase-Producing Carbapenem-Resistant Enterobacterales Bloodstream Infections.

Noncarbapenemase-producing carbapenem-resistant Enterobacterales (non-CP-CRE) are increasingly recognized as important contributors to prevalent carbapenem-resistant Enterobacterales (CRE) infections. However, there is limited understanding of mechanisms underlying non-CP-CRE causing invasive disease. Long- and short-read whole-genome sequencing was used to elucidate carbapenem nonsusceptibility determinants in Enterobacterales bloodstream isolates at MD Anderson Cancer Center in Houston, Texas. We investigated carbapenem nonsusceptible Enterobacterales (CNSE) mechanisms (i.e., isolates with carbapenem intermediate resistance phenotypes or greater) through a combination of phylogenetic analysis, antimicrobial resistance gene detection/copy number quantification, porin assessment, and mobile genetic element (MGE) characterization. Most CNSE isolates sequenced were non-CP-CRE (41/79; 51.9%), whereas 25.3% (20/79) were Enterobacterales with intermediate susceptibility to carbapenems (CIE), and 22.8% (18/79) were carbapenemase-producing Enterobacterales (CPE). Statistically significant copy number variants (CNVs) of extended-spectrum ß-lactamase (ESBL) genes (Wilcoxon Test; P-value < 0.001) were present in both non-CP-CR E. coli (median CNV = 2.6×; n = 17) and K. pneumoniae (median CNV = 3.2×, n = 17). All non-CP-CR E. coli and K. pneumoniae had predicted reduced expression of at least one outer membrane porin gene (i.e., ompC/ompF or ompK36/ompK35). Completely resolved CNSE genomes revealed that IS26 and ISEcp1 structures harboring blaCTX-M variants along with other antimicrobial resistance elements were associated with gene amplification, occurring in mostly IncFIB/IncFII plasmid contexts. MGE-mediated ß-lactamase gene amplifications resulted in either tandem arrays, primarily mediated by IS26 translocatable units, or segmental duplication, typically due to ISEcp1 transposition units. Non-CP-CRE strains were the most common cause of CRE bacteremia with carbapenem nonsusceptibility driven by concurrent porin loss and MGE-mediated amplification of blaCTX-M genes. IMPORTANCE Carbapenem-resistant Enterobacterales (CRE) are considered urgent antimicrobial resistance (AMR) threats. The vast majority of CRE research has focused on carbapenemase-producing Enterobacterales (CPE) even though noncarbapenemase-producing CRE (non-CP-CRE) comprise 50% or more of isolates in some surveillance studies. Thus, carbapenem resistance mechanisms in non-CP-CRE remain poorly characterized. To address this problem, we applied a combination of short- and long-read sequencing technologies to a cohort of CRE bacteremia isolates and used these data to unravel complex mobile genetic element structures mediating ß-lactamase gene amplification. By generating complete genomes of 65 carbapenem nonsusceptible Enterobacterales (CNSE) covering a genetically diverse array of isolates, our findings both generate novel insights into how non-CP-CRE overcome carbapenem treatments and provide researchers scaffolds for characterization of their own non-CP-CRE isolates. Improved recognition of mechanisms driving development of non-CP-CRE could assist with design and implementation of future strategies to mitigate the impact of these increasingly recognized AMR pathogens.

Initial investigation of associations between feeding practices, eating behaviours, and weight status in Vietnamese children using modified questionnaires.

AIMS: This cross-sectional study aims to extend the preliminary validation of the Feeding Practices and Structure Questionnaire (FPSQ) and Children's Eating Behaviour Questionnaire (CEBQ) in the Vietnamese context by examining associations between maternal feeding practices, child eating behaviours, and child weight status. METHODS: Modified versions of the FPSQ and CEBQ were used to measure maternal feeding practices and child eating behaviours, respectively, in a sample of Vietnamese mothers of children within the age range of two to five years (n = 100). Children's weight-for-height z-scores (WHZs) were calculated using weight and height measurements obtained by clinicians. Pearson's correlation coefficients were used to examine bivariate associations between maternal feeding practices, child eating behaviours, and child WHZs. Significant variables were then entered into a multivariable regression model. RESULTS: Child WHZs were associated with maternal persuasive feeding, and child slowness in eating, enjoyment of food/food responsiveness, and emotional undereating, but in multivariable regression analysis, only persuasive feeding (ß = -0.44, p = 0.027) and slowness in eating (ß = -0.39, p = 0.036) contributed significantly to the model. CONCLUSIONS: The findings provide some evidence of construct validity for the modified questionnaires. Potential implications of dietary-related behaviours on weight status in preschool-aged children in Viet Nam are evident. However, further validation and analysis in larger datasets must be undertaken in order to examine these associations with increased certainty.

The influence of litter birth weight phenotype on embryonic and placental development at day 30 of gestation in multiparous purebred Large White sows.

The aim of this study was to understand the intrauterine biological processes associated with the low litter birth weight phenotype in pigs. Analyses were conducted on reproductive data from a purebred Large White maternal line to identify sows (>2 parities) with repeatable high or low litter birth weight phenotype (HLBWP or LLBWP). A total of 40 sows were selected (n = 20 HLBWP and n = 20 LLBWP) and bred with semen from purebred Large White boars of proven fertility. Sows were euthanized on day 28-30 of gestation (day 29.5 ± 0.6) and samples of placenta and embryos collected. Total number of embryos (TNE), embryonic weight (EW), embryonic viability, and crown-rump (CRL) measurements were recorded, along with the ovulation rate (OR) and allantochorionic fluid volume (AFV). No significant difference was detected (P > 0.05) in OR, TNE, and number of viable embryos on day 30 of gestation between the two groups. There was no significant difference in EW (LLBWP: 0.80 ± 0.05 g; HLBWP: 0.88 ± 0.04 g, P = 0.18) or CRL (LLBWP: 21.5 ± 0.7 mm; HLBWP: 21.9 ± 0.68 mm, P = 0.46). Placental development represented by the average AFV was significantly lower in the LLBWP compared to HLBWP (LLBWP: 131 ± 9.82 mL; HLBWP: 149 ± 9.39 mL, P = 0.03). In conclusion, placental development may be the main factor causing lower BW of entire litters in LLBWP sows.

Activation of Tumor-Cell STING Primes NK-Cell Therapy.

Activation of the stimulator of interferon genes (STING) pathway promotes antitumor immunity but STING agonists have yet to achieve clinical success. Increased understanding of the mechanism of action of STING agonists in human tumors is key to developing therapeutic combinations that activate effective innate antitumor immunity. Here, we report that malignant pleural mesothelioma cells robustly express STING and are responsive to STING agonist treatment ex vivo. Using dynamic single-cell RNA sequencing of explants treated with a STING agonist, we observed CXCR3 chemokine activation primarily in tumor cells and cancer-associated fibroblasts, as well as T-cell cytotoxicity. In contrast, primary natural killer (NK) cells resisted STING agonist-induced cytotoxicity. STING agonists enhanced migration and killing of NK cells and mesothelin-targeted chimeric antigen receptor (CAR)-NK cells, improving therapeutic activity in patient-derived organotypic tumor spheroids. These studies reveal the fundamental importance of using human tumor samples to assess innate and cellular immune therapies. By functionally profiling mesothelioma tumor explants with elevated STING expression in tumor cells, we uncovered distinct consequences of STING agonist treatment in humans that support testing combining STING agonists with NK and CAR-NK cell therapies.

Management of temporomandibular disorders: a rapid review of systematic reviews and guidelines.

Temporomandibular disorders (TMD) impact a significant proportion of the population. Given the range of management strategies, contemporary care should be evidence-informed for different TMD types. A knowledge-to-action rapid review of systematic reviews published in the past 5 years and guidelines published in the past 10 years concerning the management of TMD was conducted. The Cochrane, Embase, MEDLINE, PEDro, and PubMed databases were searched. A qualitative data analysis was undertaken, with quality assessment completed using the AMSTAR 2 checklist. In total, 62 systematic reviews and nine guidelines considering a range of treatment modalities were included. In concordance with current guidelines, moderate evidence supports a multi-modal conservative approach towards initial management. Contrary to existing guidelines, occlusal splint therapy is not recommended due to a lack of supporting evidence. The evidence surrounding oral and topical pharmacotherapeutics for chronic TMD is low, whilst the evidence supporting injected pharmacotherapeutics is low to moderate. In concordance with current guidelines, moderate quality evidence supports the use of arthrocentesis or arthroscopy for arthrogenous TMD insufficiently managed by conservative measures, and open joint surgery for severe arthrogenous disease. Based on this, a management pathway showing escalation of treatment from conservative to invasive is proposed.

Data Integration for the Study of Outstanding Productivity in Biomedical Research.

Our goal is to analyze improvement of scientific performance in a multidimensional outcome space, with a focus on US-based biomedical research. With the growing diversity of research databases, limiting assessment of scientific productivity to bibliometric measures such as number of publications, impact factor of journals and number of citations, is increasingly challenged. Using a wider range of outcomes, from publications through practice improvements to entrepreneurial outcomes, overcomes many current limitations in the study of research growth. However, combining such heterogeneous datasets raise three challenges: 1. gathering in one common place a variety of data shared as csv, xml or xls files, 2. merging and linking this data, that sometimes overlap, 3. assessing the impact of research production and inclusive practices in a multidimensional space, that are often missing from the datasets. We would like to present our solution for the first of those challenges, and discuss our leads for the second and third challenges.

Rescue stenting after the failure of intravenous thrombolysis and bridging thrombolysis: an initial Vietnamese report.

OBJECTIVE: Intravenous (IV) recombinant tissue plasminogen activator is the standard of care for patients with acute ischemic stroke (AIS) who present to the hospital within 4.5 hours of symptom onset. However, IV thrombolysis, even bridging thrombolysis (combining intravenous thrombolysis and mechanical thrombectomy) has limited efficacy among patients who had occlusive lesions associated with high-grade arterial stenosis requiring revascularization to improve neurological deficits. We evaluated whether rescue stenting results in good outcomes among patients after the failure of intravenous thrombolysis and bridging thrombolysis. PATIENTS AND METHODS: We retrospectively analyzed patients with AIS who underwent rescue stenting for large vessel occlusion with severe atherosclerotic stenosis between May 2020 and August 2022 at Can Tho S.I.S General Hospital. Primary outcomes included the incidence of hemorrhagic transformation and the rate of good outcomes (modified Rankin Scale < 3) at 3-month follow-up. RESULTS: We identified 13 patients who received rescue stenting after the failure of IV alteplase and bridging thrombolysis, but only 11 patients met the inclusion criteria. All patients experienced successful recanalization, and 1 (9.1%) patient experienced new infarcts. Of these 11 patients, 10 (90.9%) had good outcomes 3 months after rescue stenting. Additionally, a loading dose of dual antiplatelet therapy (DAPT) applied concurrently with IV alteplase improved the recanalization rate for large target arteries but had no significant effect on the incidence of symptomatic intracranial hemorrhage. CONCLUSIONS: Rescue stenting appears to represent an additional therapeutic option in cases that fail to resolve with IV alteplase, which may improve clinical outcomes.

Preliminary exploration of the use of the Children's Eating Behaviour Questionnaire (CEBQ) and Feeding Practices and Structure Questionnaire (FPSQ) in Vietnamese mothers.

OBJECTIVE: This preliminary pilot study aims to explore the use of the Feeding Practices and Structure Questionnaire (FPSQ) and Children's Eating Behaviour Question (CEBQ) in a sample of Vietnamese mothers. SUBJECTS/METHODS: Cross-sectional data from the FPSQ and CEBQ were collected from a convenience sample of mothers (n = 102) who attended the Ho Chi Minh City Nutrition Centre in Viet Nam. Mothers had at least one child aged 2-5 years. The reliability of the questionnaire subscales was tested using Cronbach's alpha coefficients. Face validity was assessed using dialogue from a translation-back-translation procedure undertaken by an expert committee, and cognitive interviews conducted in a subsample of mothers (n = 6). Based on these findings, exploratory factor analyses (EFAs) were performed to assess the underlying structures of both questionnaires in this sample. RESULTS: Cronbach's alpha coefficients for the original questionnaires ranged from 0.23 to 0.92. Limitations in translation and comprehension of items surfaced, warranting modifications of the questionnaires, which were subsequently examined using EFA. EFA of the FPSQ and CEBQ revealed a six-factor structure with 23 items, and a six-factor structure with 27 items, respectively, which were interpretable solutions for this sample. Cronbach's alpha coefficients were >0.70 for all subscales in the revised questionnaires. CONCLUSIONS: Modified versions of the FPSQ and CEBQ are proposed for use in Viet Nam. However, prior to their use, further reliability and validity testing must be undertaken in larger samples, including assessment of test-retest reliability and construct validity, as well as confirmatory factor analysis to verify the proposed factor structures.
