    Abstract: Despite a growing neuroimaging literature on the pathophysiology of major depressive disorder (MDD), reproducible findings are lacking, probably reflecting mostly small sample sizes and heterogeneity in analytic approaches. To address these issues, the Depression Imaging REsearch ConsorTium (DIRECT) was launched. The REST-meta-MDD project, pooling 2428 functional brain images processed with a standardized pipeline across all participating sites, has been the first effort from DIRECT. In this review, we present an overview of the motivations, rationale, and principal findings of the studies so far from the REST-meta-MDD project. Findings from the first round of analyses of the pooled repository have included alterations in functional connectivity within the default mode network, in whole-brain topological properties, in dynamic features, and in functional lateralization. These well-powered exploratory observations have also provided the basis for future longitudinal hypothesis-driven research. Following these fruitful explorations, DIRECT has proceeded to its second stage of data sharing that seeks to examine ethnicity in brain alterations in MDD by extending the exclusive Chinese original sample to other ethnic groups through international collaborations. A state-of-the-art, surface-based preprocessing pipeline has also been introduced to improve sensitivity. Functional images from patients with bipolar disorder and schizophrenia will be included to identify shared and unique abnormalities across diagnosis boundaries. In addition, large-scale longitudinal studies targeting brain network alterations following antidepressant treatment, aggregation of diffusion tensor images, and the development of functional magnetic resonance imaging-guided neuromodulation approaches are underway. Through these endeavours, we hope to accelerate the translation of functional neuroimaging findings to clinical use, such as evaluating longitudinal effects of antidepressant medications and developing individualized neuromodulation targets, while building an open repository for the scientific community.

    Abstract: Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency–Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.

    Abstract: Atrial fibrillation (AF) and hypertension are prevalent chronic disease conditions in the elderly population. In the present cross-sectional study, we investigated the association between blood pressure (BP) and AF in an elderly Chinese population. METHOD Our elderly (≥65 years) subjects were residents recruited from 6 communities in Shanghai from 2006 to 2017. Atrial fibrillation was systematically screened by rest 12-lead electrocardiogram (ECG) or by a handheld single-lead ECG. BP status was defined according to the European hypertension guidelines as optimal, normal, or high-normal BP, and stage 1, 2, or 3 hypertension. RESULT In the 6,966 participants (women 56.0%, mean age: 72.3 years), the prevalence of AF was 3.3%, and the prevalence of hypertension was 58.7% (83.7% treated). In all participants, the association with prevalent AF was negative for systolic BP (odds ratio [OR] per 10-mm Hg increase 0.79, 95% confidence interval [CI] : 0.71–0.88, P & lt; 0.0001) but positive for diastolic BP (OR per 5-mm Hg increase 1.11, 95% CI: 1.02–1.22, P = 0.02). In untreated participants (n = 3,544), the association with prevalent AF was U-shaped for both systolic and diastolic BP, with the nadir at high-normal BP and a significantly higher risk of prevalent AF in optimal systolic BP (OR: 3.11, 95% CI: 1.65–5.85, P = 0.004) and stage 2 or 3 diastolic hypertension relative to the nadir (OR: 8.04, 95% CI: 2.28–28.3, P = 0.001). CONCLUSION In the elderly population, BP shows a complicated relationship with prevalent AF, with high-normal BP at the lowest risk and optimal systolic BP and stage 2 or 3 diastolic hypertension at increased risks.

    Changes in the CHA2DS2-VASC score as a predictor of incident atrial fibrillation in older Chinese individuals: the AF-CATCH study
    Oxford University Press (OUP) ; 2022

    Abstract: Incidence of atrial fibrillation is highly associated with age and cardiovascular co-morbidities. Given this relationship, we hypothesized that the dynamic changes resulting in an increase in the CHA2DS2-VASC score over time would improve the efficiency of predicting incident atrial fibrillation on repeated screening after a negative test. Methods and results We investigated in an analysis of the AF-CATCH trial [quarterly vs. annual electrocardiogram (ECG) screening for atrial fibrillation in older Chinese individuals] data, the association between the changes in the CHA2DS2-VASC score from baseline to end-of-study visit and the risk of incident atrial fibrillation. Participants without a history of atrial fibrillation and with a sinus rhythm at baseline were randomized to the annual (usual) or quarterly 30 s (intensive) single-lead ECG screening groups. During a median follow-up of 2.1 years in 6806 participants, the incidence rate of atrial fibrillation increased from 4.2 per 1000 person-years in participants with a change in the CHA2DS2-VASC score of 0 to 6.4 and 25.8 per 1000 person-years in participants with a change in the CHA2DS2-VASC score of 1 and ≥2, respectively. A change in the CHA2DS2-VASC score of ≥2 was associated with a significantly elevated risk of incident atrial fibrillation. Conclusions Patients with substantial changes in the CHA2DS2-VASC score were more likely to develop incident atrial fibrillation, and regular re-assessments of cardiovascular risk factors in the elderly are probably worthwhile to improve the detection of atrial fibrillation.

    Abstract: The immune protective mechanisms during severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection remain to be deciphered for the development of an effective intervention approach. Methods We examined early responses of interleukin 37 (IL-37), a powerful anti-inflammatory cytokine, in 254 SARS-CoV-2–infected patients before any clinical intervention and determined its correlation with clinical prognosis. Results Our results demonstrated that SARS-CoV-2 infection causes elevation of plasma IL-37. Higher early IL-37 responses were correlated with earlier viral RNA negative conversion, chest computed tomographic improvement, and cough relief, consequently resulted in earlier hospital discharge. Further assays showed that higher IL-37 was associated with lower interleukin 6 and interleukin 8 (IL-8) and higher interferon α responses and facilitated biochemical homeostasis. Low IL-37 responses predicted severe clinical prognosis in combination with IL-8 and C-reactive protein. In addition, we observed that IL-37 administration was able to attenuate lung inflammation and alleviate respiratory tissue damage in human angiotensin-converting enzyme 2–transgenic mice infected with SARS-CoV-2. Conclusions Overall, we found that IL-37 plays a protective role by antagonizing inflammatory responses while retaining type I interferon, thereby maintaining the functionalities of vital organs. IL-37, IL-8, and C-reactive protein might be formulated as a precise prediction model for screening severe clinical cases and have good value in clinical practice.

    Abstract: Impairment of antigen-presenting functions is a key mechanism contributing to sepsis-induced immunosuppression. Recently, γδ T cells have been demonstrated as professional antigen-presenting cells (APCs); however, their role in sepsis remains unknown. In this in vitro study, the APC function of human peripheral γδ T cells was assessed using samples collected from 42 patients with sepsis and 27 age-matched healthy controls. The APC-related markers HLA-DR, CD27, CD80, and CCR7 on fresh γδT cells were significantly higher in patients with sepsis compared with matched controls; however, they responded poorly to 4-hydroxy-3-methyl-2-butenyl pyrophosphate (HMBPP) stimulation, characterized by the deactivation of these APC markers and impaired proliferation. Furthermore, the adhesion function of γδ T cells, essential for antigen presentation, was greatly reduced in patients with sepsis; for instance, in co-cultures with green fluorescent protein-expressing Escherichia coli, HMBPP-activated γδT cells from healthy individuals adhered to E. coli efficiently, whereas no such phenomenon was observed with respect to γδT cells from patients with sepsis. In line with these results, in co-cultures with isolated CD4+ αβ T cells, HMBPP-activated γδT cells of healthy individuals promoted the efficient proliferation of CD4+ αβ T cells, whereas γδT cells from patients with sepsis did not do so. In conclusion, our findings show that the antigen-presenting function of γδT cells is severely impaired in patients with sepsis and the mechanisms behind need further study.
