Abstract
Objective: To evaluate the utility of a type 3 portable monitor (PM) at home for the diagnosis of sleep disordered breathing (SDB) in patients with stable congestive heart failure (CHF). Methods: Seventy-six consecutive patients with CHF (61 males, 15 females, mean±standard deviation age (57.0±16.9) years) were enrolled from the sleep center of Peking university People's Hospital during January 2016 to January 2019, and underwent overnight, unattended home sleep apnea testing (HSAT) with a portable monitor followed by an overnight simultaneous polysomnogram (PSG) with in-laboratory portable monitor (in-lab PM) recording within one week. The consistency of apnea hypopnea index (AHI), obstructive sleep apnea index (OAI), central sleep apnea index (CAI) between HSAT and PSG as well as the in-lab PM and PSG were analyzed by Bland-Altman plot; the sensitivity and specificity of PM for the diagnosis of SDB in patients with CHF were evaluated. Results: The number of patients included in the final analysis were 65 in HSAT, 63 in in-lab PM and 65 in PSG. AHI [M(Q1,Q3)] was 26.1 (10.9,40.1) events/h by HSAT, 27.9 (11.3,43.2) events/h by in-lab PM, both were not different from AHI 29.0 (10.2,45.0) events/h by PSG (P>0.05). The AHI, OAI and CAI assessed by HSAT correlated significantly with those by PSG (r=0.892, 0.903, 0.831, P<0.05). Bland-Altman analysis of AHI, OAI, CAI by PSG versus HSAT showed a mean difference of 3.1 events/h, 0.8 events/h, 1.2 events/h; limits of consistency were -15.2 to 21.4 events/h, -9.7 to 11.3 events/h, -10.9 to 13.2 events/h, respectively. Based on a threshold of AHI ≥5 events/h, HSAT had 94.6% sensitivity, 75% specificity, compared to PSG. For detecting Cheyne-Stokes respiration (CSR), a sensitivity of 96.4%,a specificity of 97.2% were achieved, compared to PSG. Conclusion: Type 3 PM can be used to diagnose SDB in patients with CHF.

Abstract
Background:The COVID-19 pandemic has affected the delivery of face-to-face teaching especially bedside teaching for medical students in the hospitals. Rheumatology outpatient clinics have mostly become virtual or telephone consultation clinics which prevent medical students from seeing patients in person. Students are deprived of the opportunities to take rheumatology history, examining patients and seeing signs of rheumatologic diseases. New adaptations have to be made to ensure equitability and that students still receive the relevant teaching in line with their learning curriculum and to help them prepare for their examinations.Objectives:Our aims are:1)To adapt bedside teaching in the wards to simulated teaching in the classroom using trained simulated ‘patients’; and2)To create simulation teaching of patient journeys in Objective Structured Clinical Examination (OSCE) format known as Clinically Observed Medical Education Tutorials (COMET) (Nair et al., 2001).Methods:1)For simulated teaching in the classroom, we have trained our teaching colleagues as simulated or standardized patients (SPs). We write up fictitious patient histories which simulate common presentations at rheumatology clinics. We train the SPs to give as accurate a history as possible and to simulate pains in different joints (e.g. pain at the metacarpophalangeal joints and proximal interphalangeal joints in rheumatoid arthritis) on clinical examinations. For clinical presentations that are not easily simulated, we use photographs of the relevant signs. This method is used not only as formative assessments but also as end-of-placement summative assessments.2)COMET comprises 3 OSCE-style stations with a tutor each where the students perform different tasks based on a patient’s clinical problem (e.g. acute hot swollen joint). The first station is initial A-to-E assessment of the patient (using a simulator), followed by investigations and interpretations of lab results and imaging (station 2) and lastly, management (including prescribing medications) and communication skills (e.g. explain arthrocentesis to the patient).Results:The overall feedback from students is very positive. We use Likert scale to assess confidence level before and after the teaching session, and pre-session and post-session multiple choice questions to assess learning and knowledge gained.Conclusion:While simulated teaching cannot replace encounters with real patients, students do enjoy these sessions as they get to ‘experience’ a large variety of rheumatologic cases and practice their clinical skills which at times are limited with real patients due to reluctance and pain of the patients.References:[1]Nair, R., Morrissey, J., Carasco, D., Desilva, S. & Patel, V.

Abstract
Mounting evidence has shown that periodontitis is associated with diabetes. However, a causal relationship remains to be determined. Recent studies reported that periodontitis may be associated with gut microbiota, which plays an important role in the development of diabetes. Therefore, we hypothesized that gut microbiota might mediate the link between periodontitis and diabetes. Periodontitis was induced by ligatures. Glycemic homeostasis was evaluated through fasting blood glucose (FBG), serum glycosylated hemoglobin (HbA1c), and intraperitoneal glucose tolerance test. Micro-computed tomography and hematoxylin and eosin staining were used to evaluate periodontal destruction. The gut microbiota was analyzed using 16S ribosomal RNA gene sequencing and bioinformatics. Serum endotoxin, interleukin (IL) 6, tumor necrosis factor α (TNF-α), and IL-1β were measured to evaluate the systemic inflammation burden. We found that the levels of FBG, HbA1c, and glucose intolerance were higher in the periodontitis (PD) group than in the control (Con) group (P < 0.05). When periodontitis was eliminated, the FBG significantly decreased (P < 0.05). Several butyrate-producing bacteria were decreased in the gut microbiota of the PD group, including Lachnospiraceae_NK4A136_group, Eubacterium_fissicatena_group, Eubacterium_coprostanoligenes_group, and Ruminococcaceae_UCG-014 (P < 0.05), which were negatively correlated with serum HbA1c (P < 0.05). Subsequently, the gut microbiota was depleted using antibiotics or transplanted through cohousing. Compared with the PD group, the levels of HbA1c and glucose intolerance were decreased in the gut microbiota-depleted mice with periodontitis (PD + Abx) (P < 0.05), as well as the serum levels of endotoxin and IL-6 (P < 0.05). The serum levels of IL-6, TNF-α, and IL-1β in the PD + Abx group were higher than those of the Con group (P < 0.05). Antibiotics exerted a limited impact on the periodontal microbiota. When the PD mice were cohoused with healthy ones, the elevated FBG and HbA1c significantly recovered (P < 0.05), as well as the aforementioned butyrate producers (P < 0.05). Thus, within the limitations of this study, our data indicated that the gut microbiota may mediate the influence of periodontitis on prediabetes.

Abstract
Abstract
Introduction
Detection of delirium in hospitalised older adults is recommended in national and international guidelines. The 4 ‘A’s Test (4AT; www.the4AT.com) is a short (<2 min) instrument for delirium detection that is used internationally as a standard tool in clinical practice. We performed a systematic review and meta-analysis of diagnostic test accuracy of the 4AT for delirium detection.
Methods
We searched the following electronic databases through Ovid: MEDLINE, Embase, and PsycINFO. Additional databases were searched: CINAHL (EBSCOhost), clinicaltrials.gov and Cochrane Central Register of Controlled Trials from 2011 (4AT publication) until 21 December 2019. Inclusion criteria: older adults (≥65) across any setting of care except critical care; validation study of the 4AT against a delirium reference standard (standard diagnostic criteria or validated tool). Two reviewers independently screened abstracts and papers and performed the data extraction. Pooled estimates of sensitivity and specificity were generated from a bivariate random effects model.
Results
17 studies (n = 3,701 observations) were included. Various settings including acute medicine, surgery, stroke wards and the emergency department were represented. The overall prevalence of delirium was 24.2% (95% CI 17.8–32.1%; range 10.5–61.9%). The pooled sensitivity was 0.88 (95% CI 0.80–0.93) and the pooled specificity was 0.88 (95% CI 0.82–0.92). The methodological quality of studies was mostly good.
Conclusions
The 4AT is now supported by a substantial evidence base comparable to other well-studied tools such as the Confusion Assessment Method (CAM). The strong pooled sensitivity and specificity findings for the 4AT in this meta-analysis along with its brevity and lack of need for specific training provide support for its use as an effective assessment tool for delirium.

Abstract
OBJECTIVE COVID-19 can cause severe acute respiratory distress syndrome (ARDS). Extracorporeal membrane oxygenation (ECMO) can support gas exchange in patients failing conventional mechanical ventilation, but its role is still controversial. We performed a rapid systematic review focusing on the use of ECMO in patients with COVID-19. MATERIALS AND METHODS PubMed/MEDLINE, Google Scholar, Embase, the Cochrane Library, EBSCO and Ovid (updated 30 April 2020) were systematically searched. Case reports/Case series from COVID-19 patients treated with ECMO were included in the study. Three reviewers assessed, selected, and abstracted data from studies. All disparate opinions were resolved through discussion. RESULTS We included 13 articles for systematic evaluation, including 10 case reports and 3 case series studies, with a total of 72 patients. We search for the following information: First author of articles; Patient's location; age; gender; body mass index (BMI); Comorbidities; Time on ECMO; Mode of ECMO; treatments and clinical outcomes. As of all reporting times, our data show that 38 patients (52.8%) have died definitively, 13 patients (18.0%) were still receiving ECMO treatment, 12 patients (16.7%) were alive, 7 patients (9.7%) were recovery and 2 cases (2.8%) remained hospitalized. CONCLUSIONS ECMO plays an important role in the stabilization and survival critically ill patients with COVID-19, but the usefulness of ECMO in reducing the mortality of severe ARDS caused by COVID-19 was limited. Therefore, a larger sample size study and a comprehensive analysis of evaluating the medical value of using ECMO on COVID-19 patients are urgently required.

Abstract
Growing evidence shows that a homozygous 6·7-kb deletion of the novel anti-inflammatory molecule leukocyte immunoglobulin-like receptor A3 (LILRA3) is associated with many autoimmune disorders. However, its effects on pathogenesis of inflammatory bowel disease (IBD) have yet not been clarified. LILRA3 is mainly expressed in monocytes, whereas its effects on biological behaviors of monocytes have not been systematically reported. In our study, to investigate the association between LILRA3 polymorphism and IBD susceptibility, LILRA3 polymorphism was assessed in 378 IBD patients and 509 healthy controls. Quantitative real time PCR (qRT-PCR), Western blot and immunohistochemistry (IHC) were employed to detect the LILRA3 expression in IBD patient blood and intestinal samples. The human U937 monocyte cell line was employed to establish LILRA3 over-expressing cells and the effects of LILRA3 on the biological behaviors of U937 cells were systematically explored. Although no association of the polymorphism with IBD development was found, LILRA3 expression was markedly increased in IBD patients compared with healthy controls. Over-expression of LILRA3 in monocytes led to significant decreases in secretion of interferon (IFN)-γ, tumor necrosis factor (TNF)-α and interleukin (IL)-6. Additionally, LILRA3 abated monocyte migration by reducing the expression of several chemokines and enhanced monocyte phagocytosis by increasing CD36 expression. Furthermore, LILRA3 promoted monocyte proliferation through a combination of Akt and extracellular receptor kinase/mitogen-activated protein kinase (Erk/MEK) signaling pathways. We report for the first time, to our knowledge, that LILRA3 is related to IBD and functions as an anti-inflammatory modulator in U937 cells.

Abstract
AIMS The aims of the study were to (i) improve the evaluation criteria of detoxifying Jatropha curcas L. cake (JCC), (ii) isolate and characterize a JCC tolerant strain, (iii) explore its JCC detoxifying potential. METHODS AND RESULTS The zebrafish was employed as a survival model to screen the strains capable of detoxifying JCC. A strain identified as Mucor circinelloides SCYA25, which is highly capable of degrading all toxic components, was isolated from soil. Different solid-state fermentation parameters were optimized by response surface methodology. The optimal values for inoculation amount, moisture content, temperature, and time were found to be 18% (1·8 × 106 spores g-1 cake), 66%, 26, and 36 days, respectively, to achieve maximum detoxification of the JCC (92%). Under optimal fermentation conditions, the protein content of JCC was increased, while the concentrations of ether extract, crude fiber, toxins, and anti-nutritional substances were all degraded considerably (P < 0·05). Scanning electron microscopy and Fourier transform infrared spectrometer analysis revealed that the fermentation process could disrupt the surface structure and improve the ratio of α-helix to β-folding in the JCC protein, which may improve the digestibility when the detoxified JCC is used as a feedstuff. CONCLUSIONS Our results indicate that M. circinelloides SCYA25 is able to detoxify JCC and improve its nutritional profile, which is beneficial to the safe utilization of JCC as a protein feedstuff. SIGNIFICANCE AND IMPACT OF THE STUDY The newly identified M. circinelloides SCYA25 detoxified JCC in a safe manner to provide a potential alternative to soybean meal for the feed industry. These results also provide a new perspective and method for the toxicity evaluation and utilization of JCC and similar toxic agricultural by-products.

Abstract
Searches for electron antineutrino, muon neutrino, and muon antineutrino disappearance driven by sterile neutrino mixing have been carried out by the Daya Bay and MINOS+ collaborations. This Letter presents the combined results of these searches, along with exclusion results from the Bugey-3 reactor experiment, framed in a minimally extended four-neutrino scenario. Significantly improved constraints on the θ_{μe} mixing angle are derived that constitute the most constraining limits to date over five orders of magnitude in the mass-squared splitting Δm_{41}^{2}, excluding the 90% C.L. sterile-neutrino parameter space allowed by the LSND and MiniBooNE observations at 90% CL_{s} for Δm_{41}^{2}<13 eV^{2}. Furthermore, the LSND and MiniBooNE 99% C.L. allowed regions are excluded at 99% CL_{s} for Δm_{41}^{2}<1.6 eV^{2}.

Abstract
OBJECTIVE Nonalcoholic fatty liver disease (NAFLD) has become a common liver disorder caused by lipid accumulation and insulin resistance (IR). Acylcarnitines have become a new biomarker of IR. However, their roles in NAFLD are still poorly studied. Thus, we performed a targeted metabolomic analysis to study the level of plasma acylcarnitines in patients with NAFLD. MATERIALS AND METHODS The levels of 34 plasma acylcarnitines were measured by a targeted metabolomic approach in NAFLD patients (n = 50) and in healthy control subjects (n = 50) by liquid chromatography-tandem mass spectrometry. Detailed demographic and clinical characteristics of all subjects were also analyzed. RESULTS The clinical presentation of IR was identified in the NAFLD group but not in the healthy control group. Significant differences were found in the levels of several short-, medium- and long-chain acylcarnitines. A high degree of correlation (r>0.7) was found between even-numbered-carbon long-chain acylcarnitines in NAFLD patients. The area under the receiver operator characteristic of long-chain acylcarnitines, especially C20 (AUC=0.952), C16:1 (AUC=0.949) and C14:1OH (AUC=0.944) acylcarnitines, was greater in NAFLD patients than in healthy control subjects. CONCLUSIONS The accumulation and disorders of acylcarnitines are associated with NAFLD. A positive correlation between even-numbered-carbon long-chain acylcarnitines was found, and these even-numbered-carbon long-chain acylcarnitines. could be used as potential novel screening markers for nonalcoholic fatty liver disease.

Abstract
OBJECTIVE The aim of this study was to investigate the effects of salinomycin (Sal) on expressions of baculoviral IAP repeat-containing 5 (BIRC5) and Nei endonuclease VIII-like 2 (NEIL2) and radiotherapy sensitivity of nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS Human NPC CNE-2 cell lines were used as research objects in this study. Subsequently, the cells received intervention with Sal at different concentrations, radioactive rays at different doses and Sal combined with radioactive rays. The growth inhibition rate of CNE-2 cells was detected via methyl thiazolyl tetrazolium (MTT) assay. The dose-effect relations of Sal, radioactive rays and combination therapy with the inhibitory effect on CNE-2 cells were obtained. CNE-2 cells receiving intervention with Sal at an appropriate concentration or radioactive rays at an appropriate dose alone and Sal combined with radioactive rays were used as intervention groups (Sal group, Radiation group and Combination group). However, those added with an equal amount of DMSO were set as Control group. Next, the cycle, apoptosis and apoptotic morphology of CNE-2 cells were observed via flow cytometry and Hoechst assay, respectively. Moreover, the expressions of apoptosis-related proteins Caspase-3, B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax), as well as BIRC5 and NEIL2 proteins in CNE-2 cells were determined using Western blotting. RESULTS Under the intervention with Sal or radioactive rays alone, the growth inhibition rate of CNE-2 cells rose in a concentration/dose-dependent manner. With the increase in Sal concentration in combination therapy, the growth inhibition rate of CNE-2 cells significantly increased (p<0.05). Compared with Control group, Sal group, Radiation group, and Combination group exhibited remarkably lower colony formation rate, higher proportion of CNE-2 cells in the G2/M phase, enhanced apoptosis of CNE-2 cells with nuclear fragmentation, increased expressions of pro-apoptotic proteins Caspase-3 and Bax, decreased expression of anti-apoptotic protein Bcl-2, and lower protein expressions of BIRC5 and NEIL2 in cells (p<0.05). Compared with Radiation group, the Combination group had significantly decreased colony formation rate, increased proportion of CNE-2 cells in the G2/M phase, enhanced apoptosis of CNE-2 cells with more nuclear fragmentation and other apoptosis characteristics, increased expressions of pro-apoptotic proteins Caspase-3 and Bax, decreased expression of anti-apoptotic protein Bcl-2, and decreased protein expressions of BIRC5 and NEIL2 in cells (p<0.05). CONCLUSIONS Sal enhances the radiotherapy sensitivity of NPC and reduces the protein expressions of BIRC5 and NEIL2 in cells.

Abstract
Abstract
Introduction
Social relationships are important for health. In some relationships, women learn to self-silence, or to inhibit self-expression to avoid conflict or loss. Self-silencing is associated with reported psychiatric and physical symptoms, but no studies have examined whether self-silencing is related to worse sleep or cardiovascular (CV) health. We tested relationships of self-silencing to sleep and carotid plaque in midlife women; secondary analyses examined whether sleep mediated or moderated relationships between self-silencing and plaque.
Methods
In an ongoing community-based study of nonsmoking women, 304 women aged 40-60 were assessed at baseline; 157 of these women have been assessed 5 years later. At baseline, women reported on self-expression in their current/last intimate relationship via the Silencing the Self Scale. At both visits, women provided self-reports (demographics, medical history, CESD depression, PSQI sleep quality), physical measures, actigraphy (total sleep time [TST], wake after sleep onset [WASO], and efficiency), and carotid artery ultrasound to quantify plaque. Relationships of self-silencing and subscales to sleep (subjective and actigraphic sleep at baseline and averaged across visits) and carotid plaque (0, 1, ≥2) were tested in linear regression and multinomial regression models, respectively, adjusted for demographic and health indices, including depressive symptoms and snoring.
Results
At baseline, women (72% White) were on average 54 years old; 44% reported poor sleep quality, 46% had plaque (24% score ≥2), and average TST, WASO, and efficiency were 6.2 hrs, 46 min, and 84%, respectively. At baseline, self-silencing (particularly the tendency to judge oneself by external standards) was related to worse sleep quality (p=.001), but better actigraphic WASO (p=.02) and efficiency (p=.02). Self-silencing was related to worse average sleep quality across visits (p=.001). Self-silencing related to higher odds of baseline plaque ≥2 [OR(95% CI)=1.14 (1.02,1.28), p=.02], yet sleep did not explain or moderate this relationship.
Conclusion
Self-silencing was associated with worse subjective, but better actigraphic sleep at baseline, and with poorer sleep quality over 5 years. Self-silencing related to carotid atherosclerosis, yet sleep did not appear to impact this relationship. Emotional expression is relevant to midlife women’s sleep and CV health.

Abstract
Abstract
Introduction
The concept of Sleep Health (SH) was developed to provide a multidimensional framework consisting of characteristics of sleep that have been closely associated with physical and mental well-being. Identification of key factors associated with SH can identify targets for intervention for its improvement. This study aimed to identify factors related to SH among middle-aged and older adults.
Methods
A valid Sleep Health Composite Measure was recently developed from the data of the 2014 Core Survey of the Health and Retirement Survey and was used to assess overall SH in middle-aged and older adults. Spearman’s correlations, T-test, and Kruskal-Wallis tests were used to explore the association of SH with age, gender, self-rated health, chronic disease burden, disability, pain, and modifiable lifestyle behaviors (physical activity, smoking, alcohol, sleep medication).
Results
Our sample included 6,095 adults with mean age of 68 years (SD=10.1; range 50-99 years). The majority were female (59.7%) and white (77%). Correlations showed significant moderate associations between SH and self-rated health (r=.404), sleep medications (r=.390), pain (r=-.315). There were significant but small associations between vigorous activity (r=-.193), alcohol (r=.112), currently smoking (r=-.089) and SH. SH was significantly worse among women compared to men (t(6093)=6.996, p<0.001). Furthermore, SH scores were significantly different between middle-aged versus older adults (p<0.001); varying levels of self-rated health (p<0.001), number of chronic diseases (p<0.001), and degree of physical disability (p<0.001).
Conclusion
These findings provide evidence of factors related to SH among middle-aged and older adults, providing targets for intervention to improve health in this population. Age-related differences in relation to SH indicate intervention tailored for middle-aged adults may improve health outcomes as they age. Future studies are warranted to extend these findings using multivariable statistical approaches.
