The CCL2-CCR4 axis promotes Regulatory T cell trafficking to canine glioma tissues.

PURPOSE: Spontaneously occurring glioma in pet dogs is increasingly recognized as a valuable translational model for human glioblastoma. Canine high-grade glioma and human glioblastomas share many molecular similarities, including the accumulation of immunosuppressive regulatory T cells (Tregs) that inhibit anti-tumor immune responses. Identifying in dog mechanisms responsible for Treg recruitment may afford to target the cellular population driving immunosuppression, the results providing a rationale for translational clinical studies in human patients. Our group has previously identified C-C motif chemokine 2 (CCL2) as a glioma-derived T-reg chemoattractant acting on chemokine receptor 4 (CCR4) in a murine orthotopic glioma model. Recently, we demonstrated a robust increase of CCL2 in the brain tissue of canine patients bearing high-grade glioma. METHODS: We performed a series of in vitro experiments using canine Tregs and patient-derived canine glioma cell lines (GSC 1110, GSC 0514, J3T-Bg, G06A) to interrogate the CCL2-CCR4 signaling axis in the canine. RESULTS: We established a flow cytometry gating strategy for identifying and isolating FOXP3+ Tregs in dogs. The canine CD4 + CD25high T-cell population was highly enriched in FOXP3 and CCR4 expression, indicating they are bona fide Tregs. Canine Treg migration was enhanced by CCL2 or by glioma cell line-derived supernatant. Blockade of the CCL2-CCR4 axis significantly reduced migration of canine Tregs. CCL2 mRNA was expressed in all glioma cell lines, and expression increased when exposed to Tregs but not CD4 + helper T-cells. CONCLUSION: Our study validates CCL2-CCR4 as a bi-directional Treg-glioma immunosuppressive and tumor-promoting axis in canine high-grade glioma.

Physical, mental, and behavioral health after adverse and benevolent childhood experiences: A comparison of two adversity conceptualizations.

OBJECTIVE: Adverse and benevolent childhood experiences (ACEs and BCEs) impact health across the lifespan. No known study has investigated these associations across different health domains using a representative adult sample. This study examined the associations between adult physical, mental, and behavioral health with ACEs and BCEs based on two ACEs conceptualizations. METHOD: A cross-sectional population-based survey was conducted in Hong Kong. Thirteen ACEs were measured and conceptualized as cumulative ACE scores and ACE patterns. Self-reports of BCEs; 10 physical health problems; current mental health; posttraumatic stress; history of diagnosed mental illness; suicidal thought and suicide attempt; and engagement in three health risk behaviors (smoking, illicit substance misuse, binge drinking) were also included. A series of regression analyses were conducted to examine the association between childhood experiences and health. RESULTS: In a random sample of 1,070 Hong Kong adults (Mage = 41.78 years; 53.93% female; mean ACEs = 1.64), 649 (60.65%) reported at least one ACE. Four ACE patterns were identified (Low ACEs, Household Instability, Household Violence, and High ACEs). Higher ACE scores associated with poorer health in a dose-response fashion. Two ACE patterns shared similar average ACE scores but differentially linked with outcomes across health domains. High BCEs negatively associated with mental and behavioral health problems. CONCLUSIONS: Public health responses to ACEs should consider both the accumulation and co-occurrence of ACE exposure. Schools, neighborhoods, and the wider community should take an active role in helping children and families create more positive experiences as a universal prevention strategy to safeguard population health.

Paediatric Uveitis - the uniqueness in clinical presentation and the efficacy of biologics treatment.

AIMS: To evaluate unique clinical characteristics of paediatric uveitis in our locality and treatment outcomes especially the efficacy of biologics. METHODS: This was a retrospective cohort. RESULTS: 37 paediatric uveitis cases involving 67 eyes were included. Male-to-female ratio was 1:1.3. Mean age of uveitis onset was 11 ± 3.7 (4-18). 81.1% cases suffered from bilateral uveitis. 75.7% cases were chronic uveitis. Nearly half of the cases (40.5%) presented with anterior uveitis. The predominant diagnosis of uveitis in our cohort was idiopathic. Unlike studies from other populations, the associated systemic conditions in this mostly Chinese cohort were Behçet's disease (8.1%), tubulointerstitial nephritis and uveitis (8.1%) and HLA-B27 associated uveitis (8.1%). Steroid response was a common phenomenon, observed in 40.5% of cases. The most common complication was posterior synechiae (45.9%), followed by cataract (37.8%), glaucoma (27.0%), band keratopathy (18.9%) and macular oedema (13.5%). 3/37 patients encountered either first attack of uveitis or flare after receiving COVID-19 vaccine. 54.1% of patients required systemic steroid for disease control. The majority required steroid sparing immunotherapy, including Methotrexate (43.2%), Mycophenolate Mofetil (24.3%), Cyclosporine A (8.1%), Azathioprine (5.4%) and Tacrolimus (2.7%). Resistant cases required biologics including tumour necrosis factor alpha inhibitors (Adalimumab 32.4%, Infliximab 2.7%) and interleukin-6 inhibitors (Tocilizumab 2.7%). CONCLUSIONS: Clinical presentation of the local paediatric uveitis differs from previously described features in Caucasian and other populations. According to our experience as a tertiary eye centre, Behçet's disease, tubulointerstitial nephritis and uveitis and HLA-B27 associated uveitis were more often encountered than Juvenile Idiopathic Arthritis associated uveitis. Our report evaluated the efficacy of immunomodulatory therapy and biologics in controlling uveitis and reducing ocular complications.

Quality of life improvement from thoracoscopic atrial fibrillation ablation in women versus men: a prospective cohort study.

OBJECTIVES: Thoracoscopic ablation has proven to be an effective and safe rhythm control strategy, especially for persistent atrial fibrillation. However, its impact on quality of life (QoL) and potential gender differences remains unclear. METHODS: This prospective, single-centre observational study included consecutive patients with symptomatic atrial fibrillation undergoing thoracoscopic ablation. QoL was measured using the Short Form 36 (SF-36) and Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaires and longitudinal trend analysis including linear mixed models was used to assess gender-specific differences. RESULTS: A total of 191 patients were included; mean age 63.9 ± 8.6 years, 61 (31.9%) women and 148 (77.5%) with non-paroxysmal atrial fibrillation. Women were older, more symptomatic and reported lower baseline QoL. AFEQT summary scores substantially improved after three months (relative increase 51.5% from baseline; P < 0.001) and persisted up to 1-year (57.2%; P < 0.001). Women showed substantial QoL improvement, which was comparable to men at 1 year. Distinct gender-related trajectories for AFEQT were observed. Women showed more often clinically important decline over time, yet AF recurrence and age were predictive factors in both men and women. Patients with AF recurrence also experienced QoL improvements, albeit to a lesser extent than those in sinus rhythm (61.3% vs 26.9%, P < 0.001), with no differences between men and women. CONCLUSIONS: Thoracoscopic ablation for atrial fibrillation results in substantial QoL improvement and was comparable for men and women. Understanding sex-specific and age-related trajectories is important to further enhance patient-centred atrial fibrillation care.

A novel mathematical template for developing fDOM probe fluorescence signal correction models for freshwaters.

The reliable application of field deployable fluorescent dissolved organic matter (fDOM) probes is hindered by several influencing factors which need to be compensated. This manuscript describes the corrections of temperature, pH, turbidity and inner filter effect on fluorescence signal of a commercial fDOM probe (fDOMs). For this, Australian waters with wide ranging qualities were selected, e.g. dissolved organic carbon (DOC) ranging from ∼1 to ∼30 mg/L, specific UV absorbance at 254 nm from ∼1 to ∼6 L/m/mg and turbidity from ∼1 to ∼ 350 FNU. Laboratory-based model calibration experiments (MCEs) were performed. A model template was developed and used for the development of the correction models. For each factor, data generated through MCEs were used to determine model coefficient (α) values by fitting the generated model to the experimental data. Four discrete factor models were generated by determination of a factor-specific α value. The α values derived for each water of the MCEs subset were consistent for each factor model. This indicated generic nature of the four α values across wide-ranging water qualities. High correlation between fDOMs and DOC were achieved after applying the four-factor compensation models to new data (r, 0.96, p < 0.05). Also, average biases (and %) between DOC predicted through fDOMs and actual DOC were decreased by applying the four-factor compensation model (from 3.54 (60.9%) to 1.28 (16.7%) mg/L DOC). These correction models were incorporated into a Microsoft EXCEL-based software termed EXOf-Correct for ready-to-use applications.

Higher risk of incident diabetes among patients with primary hyperparathyroidism.

OBJECTIVES: There is relatively scarce data regarding the association between primary hyperparathyroidism (PHPT) and incident diabetes in large population-based longitudinal studies. We aimed to evaluate the risk of incident diabetes in individuals with and without PHPT and investigate the association between serum calcium concentrations and the risk of incident diabetes in patients with PHPT. METHODS: We included 2749 PHPT patients and 13,745 age, sex and index year matched non-PHPT individuals during 2000-2019. We used Cox regression models to compare the risk of incident diabetes in individuals with and without PHPT, and the risk of incident diabetes in PHPT patients with serum calcium concentration above and below the median value. The association between serum calcium concentrations and the risk of incident diabetes was examined by restricted cubic spline analyses in patients with PHPT. RESULTS: During a median follow-up time of 5.17 years (IQR 2.17, 9.58), 433 patients (15.75%) with PHPT and 2110 individuals (15.35%) without PHPT developed diabetes, respectively. Patients with PHPT had a higher incidence rate of diabetes compared to non-PHPT individuals (27.60 [95% CI 25.00, 30.30] vs. 23.90 [95% CI 22.80, 24.90] per 1000 person-years, log-rank test p = .007]. Crude Cox regression model showed PHPT was associated with a 15% higher risk of incident diabetes (HR 1.15, 95%CI 1.04, 1.28). In patients with PHPT, a 44% higher risk of incident diabetes was found in patients with serum calcium concentrations above the median value (2.63 mmol/L), compared to those below the median value (HR 1.44, 95%CI 1.08, 1.90). Restricted cubic spline analyses confirmed a positive linear association between serum calcium concentrations and the risk of incident diabetes in those with PHPT (p-value for nonlinear = .751) CONCLUSIONS: Patients with PHPT had a higher risk of incident diabetes compared to non-PHPT individuals. A positive linear association was found between serum calcium concentrations and the risk of incident diabetes in patients with PHPT.

Tobacco Cessation Interventions in Non-Respiratory Cancers: A Systematic Review With Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Considering the high rates of persistent tobacco use, effective cessation interventions are needed for cancer patients and caregivers. Despite the need, there is a significant lack of research on tobacco cessation, especially for non-respiratory cancers (breast, prostate, colorectal, cervical, and bladder cancer). PURPOSE: The objective was to evaluate tobacco use and tobacco cessation interventions among patients and caregivers for non-respiratory cancers. METHODS: Randomized controlled trials assessing tobacco cessation interventions were identified. Five electronic databases were searched in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses guidelines through July 2023. Studies exclusive to lung, oral, thoracic, and head and neck cancers were excluded. Effect sizes were estimated; risk of bias was assessed. RESULTS: Of 3,304 studies, 17 were included. Interventions included behavioral (n = 6), pharmacotherapy (n = 2), and a combination (n = 9) treatment. Eight studies included a health behavior model; mean behavioral change techniques were 5.57. Pooled magnitude of the odds of cessation was positive and significant (odds ratio = 1.24, 95% confidence interval [Lower Limit 1.02, Upper Limit 1.51]) relative to usual care/placebo. Cumulative meta-analysis examined the accumulation of results over-time and demonstrated that studies have been significant since 2020. Two studies included caregivers' who were involved in the provision of social support. CONCLUSIONS: Current interventions have the potential to reduce tobacco use in non-respiratory cancers. Results may be beneficial for promoting tobacco cessation among non-respiratory cancers. There is a considerable lack of dyadic interventions for cancer survivors and caregivers; researchers are encouraged to explore dyadic approaches.

We aimed to understand effective ways for cancer patients and caregivers to quit using tobacco. We focused on non-respiratory cancers (cancers not related to breathing issues) like breast, prostate, and colorectal cancer. We reviewed 17 randomized controlled trials designed to help people quit tobacco, which included behavioral therapies (e.g., education and counseling), pharmacotherapy (i.e., medicine), and combinations of both. We found that people in these studies quit using tobacco, especially when more than one approach was used. The studies also showed that these approaches have been more successful since 2020. The research highlighted a need for more studies that include both patients and their caregivers together in the quitting process. This approach, called dyadic intervention, could be more effective in supporting patients and their caregivers. Overall, while the current approaches are promising, more research is needed to develop better ways to help cancer patients and caregivers quit smoking for longer.

Negative symptoms in treatment-resistant schizophrenia and its relationship with functioning.

BACKGROUND: Recent operational criteria for treatment-resistant schizophrenia (TRS) recognized positive and negative symptoms. TRS patients may have heterogeneity in negative symptoms, but empirical data were lacking. We aimed to characterize TRS patients based on negative symptoms using cluster analysis, and to examine between-cluster differences in social functioning. METHODS: We administered the Clinical Assessment Interview of Negative symptoms (CAINS), Brief Negative Symptom Scale (BNSS), the Positive and Negative Syndrome Scale (PANSS) and the Social and Occupational Functional Assessment (SOFAS to 126 TRS outpatients. All patients also completed the Temporal Experience of Pleasure Scale (TEPS), the Emotion Expressivity Scale (EES), and the Social Functional Scale (SFS). A two-stage hierarchical cluster analysis was performed with the CAINS, TEPS and EES as clustering variables. We validated the clusters using ANOVAs to compare group differences in the BNSS, PANSS, SOFAS and SFS. RESULTS: Clustering indices supported a 3-cluster solution. Clusters 1 (n = 46) and 3 (n = 16) exhibited higher CAINS scores than Cluster 2 (n = 64), and were negative-symptom TRS subtypes. Cluster 1 reported lower TEPS than Cluster 3; but Cluster 3 reported lower EES than Cluster 1. Upon validation, Clusters 1 and 3 exhibited higher BNSS scores than Cluster 2, but only Cluster 1 exhibited lower SOFAS and higher PANSS general symptoms than Cluster 2. Both Clusters 1 and 3 had higher self-report functioning than Cluster 2. CONCLUSION: We provided evidence for heterogeneity of negative symptoms in TRS. Negative symptoms can characterize TRS patients and predict functional outcome.

A new method for regionalization of the vertebral column in salmonids based on radiographic hallmarks.

Current procedures to establish vertebral column regionalization (e.g., histology) in fish are time consuming and difficult to apply. The aim of this study was to develop a more rapid and accurate radiology-based method for Atlantic salmon (Salmo salar). A detailed analysis of 90 animals (4 kg) led to the establishment of region-specific radiographic hallmarks. To elucidate its transferability to other salmonid species, radiography was carried out in brown trout (Salmo trutta), Arctic char (Salvelinus alpinus), rainbow trout (Oncorhynchus mykiss), pink salmon (Oncorhynchus gorbuscha), and Chinook salmon (Oncorhynchus tshawytscha). This method was also evaluated for whole ungutted fish. The vertebral column of Atlantic salmon can be subdivided into five regions (R1-R5) based on anatomy: postcranial (R1, V1, and V2), abdominal (R2, V3-V26), transitional (R3, V27-V36), caudal (R4, V37-V53), and ural (R5, V54-V59). The following specific radiographic hallmarks allow the identification of regions: (i) lack of ribs in R1, (ii) modified parapophysis of the first vertebra of R3, (iii) prominent hemal spine of the first vertebra of R4, and (iv) the separated hemal spine of the most cranial pre-ural vertebra of R5. These hallmarks were all transferable to the other salmonid species assessed. The results include a further description of various region-specific characteristics in Atlantic salmon. The method was found applicable for sedated/whole ungutted fish, verifying it as quick and easy compared to other regionalization methods. The regions defined by radiology in this study agree with the vertebral column regions recently defined for Chinook salmon (O. tshawytscha). Thus, and considering the results of this study on various salmonid species, the currently developed regionalization protocol can be generally used for salmonids.

Electric Field Gradient Calculations for Ice VIII and IX Using Polarizable Embedding: A Comparative Study on Classical Computers and Quantum Simulators.

We test the performance of the polarizable embedding variational quantum eigensolver self-consistent field (PE-VQE-SCF) model for computing electric field gradients with comparisons to conventional complete active space self-consistent-field (CASSCF) calculations and experimental results. We compute quadrupole coupling constants for ice VIII and ice IX. We find close agreement of the quantum-computing PE-VQE-SCF results with the results from the classical PE-CASSCF calculations and with experiment. Furthermore, we observe that the inclusion of the environment is crucial for obtaining results that match the experimental data. The calculations for ice VIII are within the experimental uncertainty for both CASSCF and VQE-SCF for oxygen and lie close to the experimental value for ice IX as well. With the VQE-SCF, which is based on an adaptive derivative-assembled problem-tailored (ADAPT) ansatz, we find that the inclusion of the environment and the size of the different basis sets do not directly affect the gate counts. However, by including an explicit environment, the wavefunction and therefore the optimization problem become more complicated, which usually results in the need to include more operators from the operator pool, thereby increasing the depth of the circuit.

Deep learning-based image quality assessment for optical coherence tomography macular scans: a multicentre study.

AIMS: To develop and externally test deep learning (DL) models for assessing the image quality of three-dimensional (3D) macular scans from Cirrus and Spectralis optical coherence tomography devices. METHODS: We retrospectively collected two data sets including 2277 Cirrus 3D scans and 1557 Spectralis 3D scans, respectively, for training (70%), fine-tuning (10%) and internal validation (20%) from electronic medical and research records at The Chinese University of Hong Kong Eye Centre and the Hong Kong Eye Hospital. Scans with various eye diseases (eg, diabetic macular oedema, age-related macular degeneration, polypoidal choroidal vasculopathy and pathological myopia), and scans of normal eyes from adults and children were included. Two graders labelled each 3D scan as gradable or ungradable, according to standardised criteria. We used a 3D version of the residual network (ResNet)-18 for Cirrus 3D scans and a multiple-instance learning pipline with ResNet-18 for Spectralis 3D scans. Two deep learning (DL) models were further tested via three unseen Cirrus data sets from Singapore and five unseen Spectralis data sets from India, Australia and Hong Kong, respectively. RESULTS: In the internal validation, the models achieved the area under curves (AUCs) of 0.930 (0.885-0.976) and 0.906 (0.863-0.948) for assessing the Cirrus 3D scans and Spectralis 3D scans, respectively. In the external testing, the models showed robust performance with AUCs ranging from 0.832 (0.730-0.934) to 0.930 (0.906-0.953) and 0.891 (0.836-0.945) to 0.962 (0.918-1.000), respectively. CONCLUSIONS: Our models could be used for filtering out ungradable 3D scans and further incorporated with a disease-detection DL model, allowing a fully automated eye disease detection workflow.

Mental Health Promotion in Hong Kong: A Service Evaluation of the Coolminds Pilot Study.

BACKGROUND: It is vital to improve the mental health (MH) of young people in Hong Kong, where the suicide rate has nearly doubled among those aged 15-29 years since 2014. This multi-method evaluation aimed to assess Coolminds, which promoted MH literacy by engaging students, parents, and educators in secondary schools in Hong Kong. METHODS: Students, parents, and teachers completed self-report measures before and after attending workshops aimed at raising MH literacy. Pre- and post-survey data were collected between November 2021 and August 2022. Qualitative data from participant feedback and a focus group interview with Coolminds staff were analyzed using descriptive content analysis. RESULTS: The final dataset included 2903 students, 395 parents, and 325 educators from 52 schools. Only 3 schools had engagement with all 3 key groups. Significant improvements in MH knowledge were observed after the Coolminds workshops for all 3 groups. Qualitative analysis identified a reactive approach to MH issues, and bureaucratic and logistical challenges as barriers to implementation. CONCLUSION: Findings support the effectiveness of the Coolminds curriculum in improving MH literacy for each group and the demand for MH promotions in school settings. The implementation challenges indicate the need for future initiatives to better align with local needs and practices.

Case Report: Focal, generalized, or both: does generalized network involvement preclude successful epilepsy surgery?

We present two cases with focal seizures where scalp electroencephalography (EEG) had prominent features of a developmental and epileptic encephalopathy (DEE): Case 1: a 17-year-old male with complex motor seizures whose EEG demonstrated a slow spike-and-wave pattern and generalized paroxysmal fast activity (GPFA). Case 2: a 12-year-old male with startle-induced asymmetric tonic seizures whose EEG also had a slow spike-and-wave pattern. Both patients had intracranial EEG assessment, and focal cortical resections resulted in long-term seizure freedom and resolution of generalized findings. These cases exemplify patients with focal epilepsy with networks that share similarities to generalized epilepsies, and importantly, these features did not preclude curative epilepsy surgery.

The Association Between Intolerance of Uncertainty and Mobile Phone Addiction Among Overseas Chinese Students During COVID-19: The Mediating Roles of Perceived Stress and Rumination.

Purpose: This study investigated the mechanism underlying the association between intolerance of uncertainty and mobile phone addiction among Chinese overseas students during the COVID-19 pandemic by examining the mediating roles of perceived stress and rumination. Patients and Methods: An online questionnaire survey was distributed via social media platforms popular in mainland China. The items collected demographic information and assessed intolerance of uncertainty, perceived stress, rumination, and mobile phone addiction. A total of 249 respondents completed the questionnaire. Results: The findings suggest a considerably high risk of mobile phone addiction in the study period among overseas Chinese students, as three-fourths of the participants may have been susceptible to mobile phone addiction according to the suggested cut-off point of the Chinese version of the Smartphone Addiction Scale-Short Form. Intolerance of uncertainty showed a significant positive direct effect on mobile phone addiction. The mediation analyses suggest that intolerance of uncertainty affected mobile phone addiction mainly through three pathways: the mediating effect of perceived stress, the mediating effect of rumination, and the chain mediating effect of perceived stress and rumination. Conclusion: This study enhances understanding of mobile phone addiction among Chinese overseas students and suggests the mediating roles of rumination and perceived stress in the relationship between intolerance of uncertainty and mobile phone addiction. The study also provides suggestions for interventions among Chinese students overseas.

[Functional analysis of laparoscopic intracorporeal Xing's neobladder in long-term follow-up].

Evaluation of neobladder function in patients with long-term survival and no recurrence after laparoscopic radical cystectomy and intracorporeal Xing's neobladder. The clinical data of laparoscopic radical cystectomy and intracorporeal Xing's neobladder in long-term survival patients with bladder cancer treated in Beijing Chaoyang Hospital from July 2013 to July 2018 were analyzed retrospectively. All 17 patients underwent the surgery by the same surgical team, including 15 males and 2 females, whose mean age at the time of operation was (55.9±7.6) years. Thepostoperative urinary function and renal function were summarized. All operations were successfully completed. The mean operative time was (340±62) min. All patients were followed up for a long time, with a median follow-up time of 80(70, 96) months, Urinary continence was achieved in 17 (100%)casesduring the day and 13 (76.5%) cases at night, with a median bladder volume of 350 (200, 400) ml. All patients had good urinary control after surgery, and no hydronephrosis or creatinine increase was found in reexamination.After the application of Xing's neobladder operation, the patient maintained acceptable urinary control status after the operation, and the long-term follow-up effect was satisfactory.
