Abstract
BACKGROUND Medications that are used for treatment of metabolic disorders have been suggested to be associated with the development of amyotrophic lateral sclerosis (ALS). METHODS To examine the associations of antidiabetics and statins with the subsequent risk of ALS we conducted a population-based nested case-control study of 2475 Swedish residents diagnosed with ALS during July 2006 to December 2013 and 12 375 population controls (five for each ALS case). We extracted information on filled prescriptions of antidiabetics and statins for both cases and controls from the Swedish Prescribed Drug Register during the years before ALS diagnosis. Conditional logistic regression was used to calculate odds ratios (ORs) for the associations of these medications with ALS risk. RESULTS Patients with ALS were less likely to have been prescribed with antidiabetics compared with controls [OR, 0.76; 95% confidence intervals (CI), 0.65-0.90]. Conversely, statins were not associated with ALS risk overall (OR, 1.08; 95% CI, 0.98-1.19), although a positive association was noted among women (OR, 1.28; 95% CI, 1.10-1.48). The latter association was mostly explained by ALS cases being more likely to have a first prescription of statins during the year before diagnosis compared with controls (OR, 2.54; 95% CI, 1.84-3.49). CONCLUSIONS The inverse association of antidiabetics with ALS is consistent with the previously reported inverse association between type 2 diabetes and ALS risk. The increase in prescription of statins during the year before ALS diagnosis deserves attention because it might reflect an acceleration of the course of ALS due to statin use.

Abstract
Abstract
Introduction
OSA is closely associated with increased risk of coronary artery disease. Although previous small studies have investigated coronary plaque in OSA patients, limited data are available regarding the association of OSA with plaque morphology and composition. Therefore, we aimed to quantitatively characterize and compare coronary plaque burden and composition between patients with no or mild obstructive sleep apnea (OSA) and moderate-severe OSA using coronary computed tomography angiography (CTA) in a large-scale study.
Methods
We retrospectively analyzed consecutive patients who underwent sleep monitoring and coronary CTA. Metrics reflecting coronary plaque characteristics were compared between patients with no or mild OSA with apnea hypoxic index (AHI) ≤15 and moderate-severe OSA (AHI>15). The associations of OSA with coronary plaque components were determined by logistic and linear regression analysis.
Results
A total of 854 patients were enrolled in the study. Of these, 162 did not meet the inclusion criteria and of the remaining 692 patients 400 (57.8%) had moderate-severe OSA and 292 had no or mild OSA. Patients with moderate-severe OSA had a significantly higher total plaque volume, total non-calcified plaque (NCP) volume and total low density non-calcified plaque (LD-NCP) volume, and corresponding burden than those with no or mild OSA (all with p<0.05). Multivariate logistic regression analysis revealed that moderate-severe OSA patients are more likely to have any plaque, NCP and LD-NCP than those without no or mild OSA (p<0.05). In addition, stepwise multivariate linear regression analysis further revealed an independent relationship between moderate OSA (15<AHI≤30) and more so between severe OSA (AHI>30) and, NCP volume, LD-NCP volume, NCP composition, and LD-NCP composition, following adjustment for traditional cardiovascular risk factors, compared to no or mild OSA (AHI<15) (all with a p<0.05). Moderate-severe OSA conferred a similar odds ratio for LD-NCPs (a high-risk plaque) as the usual cardiovascular risk factors.
Conclusion
In this large cross-sectional study, OSA severity was associated with high-risk plaque features independent of traditional cardiovascular risk factors, suggesting an increased risk for cardiovascular events.

Abstract
Abstract
Introduction
To determine the frequency of undiagnosed OSA patients in patients received endoscopic sinus surgery (ESS) and to investigate the effect of OSA on the perioperative management in those patients.
Methods
308 patients undergoing ESS from 2017-2019 were enrolled. The patients were divided into two groups according to whether OSA was combined. STOP-Bang questionnaire scoring system was used to classify patients into high risk and low risk for OSA. The differences between perioperative management and complications between the two groups were compared.
Results
308 consecutive cases were included, 46 cases (14.9%) combined with OSA and 108 cases (35.0%) were at high risk of OSA. OSA patients have higher morbidity of hypertension (OR, 2.05; CI, 1.07-3.92; P=0.03), hyperlipidemia (OR, 2.19; CI, 1.06- 4.51; P=0.03), longer hospitalization time(7.0±2.7 vs. 5.4±3.6, P≤0.01) and higher incidence of intubation difficulties (OR, 3.74; CI,1.39-10.1; P=0.01). Patients at high risk of OSA also had increased rates of hypertension, hyperlipidemia, coronary heart disease and post-operative cardiovascular and respiratory complications.
Conclusion
OSA or high scores of STOP-Bang are associated with increased perioperative complications in ESS patients. Preoperative OSA screening should be strengthened to improve the safety and prognosis of ESS surgery.

Abstract
BACKGROUND AND PURPOSE Neuroinflammation is known to be involved in the pathogenesis of Parkinson's disease (PD). Abnormal activation of microglia plays a key role in this pathological process. CD200R1 is a membrane glycoprotein that is expressed primarily on myeloid cells including microglia and is involved in the maintenance of microglia in a stationary state. Our previous study reported that the regulation of CD200R1 expression is altered in PD patients. Such alteration will lead to neuroinflammation and is related to the pathogenesis of PD. The possible role of promoter polymorphisms for abnormal CD200R1 expression in PD was examined in this study. METHOD The UCSC database and dual-luciferase assays were used to confirm the promoter region of CD200R1. The promoter of CD200R1 was sequenced in 457 PD patients and 520 matched healthy controls from the Chinese Han population. Dual-luciferase assays were conducted to examine the promoter activity of CD200R1. RESULTS It was confirmed that the promoter of CD200R1 is located in the region 876-146 bp upstream of the coding DNA sequence. The frequencies of rs144721913 (P = 0.001) and rs72952157 (P = 0.022) in the promoter were significantly different between the PD group and control group. rs144721913 increases the risk of PD by approximately 14-fold and rs72952157 by 2.6-fold. The dual-luciferase assay indicated that the rs144721913 T allele and the rs72952157 G allele reduced the transcriptional activity of the CD200R1 promoter. CONCLUSIONS For the first time the promoter region of CD200R1 has been defined and two potential risk polymorphisms (rs144721913 and rs72952157) in the region for PD in Chinese Han populations have been reported.

OSA & Subclinical myocardial impairment
Background
Early detection of left ventricular (LV) systolic dysfunction is crucial for patients with obstructive sleep apnea (OSA) . LV longitudinal strain (GLS), derived from automated function imaging (AFI) based on 2D echocardiography, provides a new tool to detect subclinical impairment of both global and regional myocardium. Its value in OSA remains unclear compared to traditional parameters since obesity is not uncommon in OSA, which may compromise the accuracy of AFI. We aimed to investigate the feasibility of AFI in OSA and further to explore the impact of OSA severity and degree of hypoxia on LV function.
Methods
Comprehensive transthoracic echocardiography was done in those receiving polysomnography (PSG) suspected as OSA consecutively (n = 322). All subjects were divided into 3 groups by apnea-hyponea index (AHI) by PSG (Control: AHI<5; mild-to-moderate AHI 5-30; severe: AHI≥30) and GLS and mitral annular plane systolic excursion (MAPSE) were compared among the 3 groups.
Results
322 patients with normal LVEF (≥50%) were finally analyzed. Though more segments were measured, inter- and intra- observer variability of GLS were comparable with MAPSE in a Bland-Altman analysis. For group comparison, GLS was reduced compared to the other 2 groups in the severe OSA category (p ≤ 0.001) while MAPSE showed no differences. Further analysis showed the feasibility of AFI was acceptable even in obese patients. In multivariable analysis of GLS, only maximum desaturation was an independent associated factor (p = 0.027).
Conclusions
Even in OSA patients with obesity, AFI-derived GLS is feasible. GLS is more sensitive than MAPSE or TDI for detection of reduced LV systolic function in OSA.

Abstract
Objective: To analyze the clinical,imaging and pathological features of Pleuroparenehymal fibroelastosis (PPFE). Methods: The clinieal data of a patient diagnosed as PPFE admitted in department of Respiratory and Critical Care Medicine,Beijing Hospital in April 2017 were reported and the related literatures were reviewed.With "pleuroparenehymal fibroelastosis" as the search terms, and the search time before October 1st 2017 for Wanfangdata, China National Knowledge Infrastructure(CNKI), and PubMed. Results: The patient was a 46-year-old male presented with cough, shortness of breath after exercise.A CT scan of the chest revealed bilateral, irregular pleural thickening with upper lobe predominance.After 3 years of antituberculosis treatment,the disease progressed. A diagnosis of pleuroparenehymal fibroelastosis (PPFE) was confirmed by CT guided lung biopsy. A total of 132 cases were reported (including 1 case in Chinese). 88 of them were confirmed by pathology with detailed data.Clinical data of 89 reported cases with PPFE including 48 males and 41 females aged 13 to 85 years were enrolled and analyzed in the study.The common symptoms were dyspnea(62%, 55 cases),cough(58%, 52 cases),recurrent respiratory tract infection(17%, 15 cases).The main CT features are reported:pleural thickening(87%,77 cases), recurrent pneumothorax(52%,46 cases), traction bronchiectasis(30%, 27 cases),subpleural comsolidation(20%, 18 cases). All patients were proven PPFE by biopsy.34 cases received corticosteroid, 5 cases received lung transplant operation.40 cases died during the follow-up from 4 month to 84 month. Conclusions: Pleuroparenehymal fibroelastosis is a rare disease.The imaging findings were dominated by both upper lobes. Lung biopsy might be necessary. PPFE is often misdiagnosed as pulmonary tuberculosis/obsolete pulmonary tuberculosis,asbestosis,connective tissues disease and Drug-induced pneumonitis.There was no consensus on the treatment.

Abstract
Objective: To summarize the clinical and genetic characteristics of children with mitochondrial epilepsy. Methods: Clinical data of 62 children who were clinically and genetically diagnosed with mitochondrial epilepsy by the Department of Neurology, Beijing Children's Hospital from October 2011 to December 2018 were analyzed retrospectively, and the control of epilepsy was followed up. T test or χ(2) test were used to analyze the related factors affecting the prognosis of epilepsy between the effective group and the ineffective group. Results: Of the 62 patients, 33 were male and 29 were female. The age of onset was 3.38 (0-12.00) years; for the type of seizures, 68% (42/62) of the patients had focal seizures, generalized or secondary generalized tonic-clonic seizures were seen in 32% (20/62), myoclonic seizures in 23% (14/62), spastic seizures in 7 cases, tonic seizures in 4 cases, absence seizure, atonic seizure and clonic seizure in 1 case each; 16 cases (26%) had status epilepticus, of whom 6 cases had epilepsia partialis continua; 52% (32/62) had 2 or more types of seizures. The clinical phenotypes were mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) in 29 cases, Leigh syndrome (LS) in 11 cases, combined oxidative phosphorylation deficiency in 6 cases, myoclonus epilepsy with ragged-red fibers in 5 cases, Alpers syndrome in 4 cases, pontocerebellar hypoplasia type 6 and mitochondrial DNA depletion syndrome 9 in 2 cases each, mitochondrial complex Ⅰ deficiency nuclear type 20, progressive cavitating leukoencephalopathy, and biotinidase deficiency in 1 case each. Of the 62 cases, 40 cases (65%) had mitochondrial DNA (mtDNA) variations, of which 26 cases had m.3243A>G variants, 6 cases had m.8344A>G variants, and 3 cases had m.8993T>G/C variants, m.3271T>C, m.3481G>A, m.3946G>A, m.13094T>C, m.14487T>C variant was in 1 case each; nuclear DNA (nDNA) variations were identified in 22 cases (35%), of which 7 cases carrying variations in mitochondrial ammonia acyl tRNA synthetase coding gene, mutations in POLG and the gene encoding complex Ⅰ were in 4 cases each, variations in SUCLG1 and SDHA genes were in 2 cases each, and variations in PDHA1, BTD and TRIT1 genes were in 1 case each. Forty-three patients were followed up, and the follow-up time was 20 (3-84) months. According to the follow-up results, the anti-epilepsy treatment was effective in 19 cases (44%) and ineffective in other 24 cases (56%). The onset age of the effective group was 3.42 (0-11.50) years and that of the ineffective group was 0.92 (0-9.50) years. The onset duration of the effective group was 0 (0-7.00) years and that of the ineffective group was 0 (0-4.83) years. There was no significant difference between the effective group and the ineffective group (t=1.662, 0.860; P=0.104, 0.395). In the effective group and the ineffective group, 12 cases and 9 cases used less than 2 kinds of antiepileptic drugs, 7 cases and 15 cases used more than or equal to 2 kinds of antiepileptic drugs, 13 and 15 cases had first epilepsy, 6 and 9 cases had non-first epilepsy, 14 and 11 cases had mtDNA variation, 5 and 13 cases had nDNA variation, respectively. There was no significant difference between the two groups (χ(2)=2.794, 0.164, 3.380; P=0.095, 0.686, 0.066). Conclusions: The types of seizures with mitochondrial epilepsy in children varied, with focal motor seizures being the most common, followed by generalized or secondary generalized tonic-clonic seizures. Most children have more than two types of seizures. MELAS is the most common clinical phenotype, followed by LS; mtDNA variation is the dominant gene variation, of which m.3243A>G variation is the most common hotspot variation, followed by gene variation encoding mitochondrial aminoacyl tRNA synthase.

Abstract
Abstract
Background
Recurrent pericarditis (RP) is managed with nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids (CS), and colchicine; up to 15% of pericarditis patients experience multiple recurrences. Interleukin 1 (IL-1) is an important cytokine in the pathophysiology of RP. Rilonacept (KPL-914) is a recombinant fusion protein which binds IL-1α and IL-1β. An ongoing Phase 2 study of rilonacept demonstrated improvements in RP symptoms and inflammation.
Purpose
To evaluate the efficacy and safety of subcutaneous (SC) rilonacept in patients with RP in a Phase 3, randomized, placebo-controlled trial.
Methods
RHAPSODY is a double-blind, placebo-controlled, randomized-withdrawal trial; ∼50 patients will be enrolled (Figure). Patients (≥12 y) must present with at least a third pericarditis episode (all etiologies except infectious and malignant) characterized by a pain score ≥4 on the 11-point Numeric Rating Scale (NRS) and C-reactive protein (CRP) ≥1 mg/dL at screening. Patients may be receiving stable doses of analgesics, NSAIDs, colchicine, and/or CS. After a loading dose (320 mg SC in adults and 4.4 mg/kg SC in children), all patients will receive weekly rilonacept (160 mg SC in adults and 2.2 mg/kg SC in children) during the run-in period. Patients able to taper and discontinue concomitant pericarditis medications and achieve clinical response (mean daily NRS score ≤2.0 during the 7 days before randomization and CRP level ≤0.5 mg/dL) will be randomized 1:1 in a blinded fashion to continued rilonacept or matching placebo weekly SC injections. Investigators may choose different treatments for pericarditis recurrences based on patient clinical status, including bailout rilonacept, while maintaining the blind to prior treatment assignment. The primary efficacy endpoint is time to pericarditis recurrence (adjudicated by an independent committee) in the randomized-withdrawal portion of the study. Secondary efficacy endpoints are the proportion of patients maintaining a clinical response, percentage of days with NRS pain score ≤1, and percentage of patients with no-to-minimal pericarditis symptoms based on patient global assessment. Safety evaluations include adverse events monitoring, physical examinations, and laboratory tests.
Figure 1
Conclusions
RHAPSODY is a pivotal Phase 3 trial evaluating the efficacy and safety of rilonacept in patients with RP using a double-blind, placebo-controlled, randomized-withdrawal design. The results of this study may inform the management of RP.

Abstract
The precise measurement of the spectrum of protons, the most abundant component of the cosmic radiation, is necessary to understand the source and acceleration of cosmic rays in the Milky Way. This work reports the measurement of the cosmic ray proton fluxes with kinetic energies from 40 GeV to 100 TeV, with 2 1/2 years of data recorded by the DArk Matter Particle Explorer (DAMPE). This is the first time that an experiment directly measures the cosmic ray protons up to ~100 TeV with high statistics. The measured spectrum confirms the spectral hardening at ~300 GeV found by previous experiments and reveals a softening at ~13.6 TeV, with the spectral index changing from ~2.60 to ~2.85. Our result suggests the existence of a new spectral feature of cosmic rays at energies lower than the so-called knee and sheds new light on the origin of Galactic cosmic rays.

Abstract
Objective: To summarize the clinical features of Bickerstaff brainstem encephalitis (BBE) in children. Methods: In this retrospective study, data of 19 patients with BBE (11 males and 8 females) were collected from Department of Neurology, Beijing Children's Hospital from October 2015 to January 2018. The clinical features, treatment and prognosis were analyzed. Results: The onset age of BBE ranged from 1 year and 8 months to 12 years and 11 months. There were 18 cases with preceding infection. The most common infection was upper respiratory tract infection (9 cases), followed by simple fever (5 cases). The most common initial neurological symptoms were lethargy or disturbance of consciousness (8 cases), followed by limb weakness (5 cases). There were 6 cases of simple BBE and 13 cases of BBE overlapping Guillain-Barré syndrome (GBS). Besides the characteristic triad of altered mental status, ataxia, and ophthalmoplegia, there were other symptoms including convulsion (5 cases), diplopia (3 cases), nystagmus (7 cases), facial muscular weakness (7 cases),bulbar palsy (13 cases) and autonomic nerve symptoms (9 cases). Hypo or areflexia was seen in 16 cases. Positive Babinski's signs were seen in 8 cases. Hyponatremia was present in 10 cases in whom 4 showed severe hyponatremia. Albumin-cytological dissociation of cerebrospinal fluid was seen in 10 cases. The autoimmune antibodies were examined in all 19 patients. Anti-ganglioside antibodies including anti-GM1 IgG antibody was positive in 2 patients and one of whom was also found with positive anti-GD1b IgG antibody. Anti-GQ1b IgG antibody was present in 2 patients. Electromyography was performed in 14 cases and 8 cases, who were all BBE overlapping GBS, showed neurological damage. A total of 16 cases were monitored by video electroencephalography and 8 cases showed slow waves of background. In addition to, interictal focal discharge was detected in 2 cases. T2 fluid-attenuated inversion recovery (FLAIR) sequence abnormal signals were detected in 3 of 18 cases performed brain magnetic resonance imaging (MRI), and lesions involved with brainstem, basal ganglia, thalamus, cerebellum, corpus callosum and cerebral cortex. Lesions involved cervical and thoracic spinal cord were found in 1 out of 11 cases for whom spinal cord MRI was performed. All of the 4 cases who underwent enhanced MRI of spinal had partial nerve roots enhancement. All of the 19 patients received 1 to 2 courses of intravenous immunoglobulin therapy, and 2 cases also received plasma exchange. Fifteen cases received steroid therapy. The following-up period ranged from 3 months to 2.5 years. Two cases were lost to follow-up. Twelve cases achieved a full recovery within 3 months. Three cases recovered within 6 months. One case still had slight limb weakness and ataxia after 1 year and 8 months of follow-up, and another case had left autonomic nerve symptoms in the follow-up of 2 years and 3 months. Both of them were BBE overlapping GBS. Conclusions: Children's BBE is similar to that in adults, and is frequently found overlapped with GBS. Furthermore, it is sometimes accompanied by central nervous system demyelination disease. The antiganglioside antibodies are not often detectable. Immunoglobulin therapy could usually achieve good response. The prognosis of simple BBE is good in most situations. For BBE overlapping GBS, the more severe the limb weakness during the peak of disease is, the slower the recovery would be.

Abstract
OBJECTIVE Knee osteoarthritis (KOA) is a heterogeneous condition representing a variety of potentially distinct phenotypes. The purpose of this study was to apply innovative machine learning approaches to KOA phenotyping in order to define progression phenotypes that are potentially more responsive to interventions. DESIGN We used publicly available data from the Foundation for the National Institutes of Health (FNIH) osteoarthritis (OA) Biomarkers Consortium, where radiographic (medial joint space narrowing of ≥0.7 mm), and pain progression (increase of ≥9 Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] points) were defined at 48 months, as four mutually exclusive outcome groups (none, both, pain only, radiographic only), along with an extensive set of covariates. We applied distance weighted discrimination (DWD), direction-projection-permutation (DiProPerm) testing, and clustering methods to focus on the contrast (z-scores) between those progressing by both criteria ("progressors") and those progressing by neither ("non-progressors"). RESULTS Using all observations (597 individuals, 59% women, mean age 62 years and BMI 31 kg/m2) and all 73 baseline variables available in the dataset, there was a clear separation among progressors and non-progressors (z = 10.1). Higher z-scores were seen for the magnetic resonance imaging (MRI)-based variables than for demographic/clinical variables or biochemical markers. Baseline variables with the greatest contribution to non-progression at 48 months included WOMAC pain, lateral meniscal extrusion, and serum N-terminal pro-peptide of collagen IIA (PIIANP), while those contributing to progression included bone marrow lesions, osteophytes, medial meniscal extrusion, and urine C-terminal crosslinked telopeptide type II collagen (CTX-II). CONCLUSIONS Using methods that provide a way to assess numerous variables of different types and scalings simultaneously in relation to an outcome of interest enabled a data-driven approach that identified key variables associated with a progression phenotype.

Abstract
Abstract
Introduction: We report discovery and characterization of E7766, a structurally novel STING agonist, as a potential immunotherapy for solid cancers through intratumoral (IT) administration and for Bacillus Calmette-Guerin (BCG) unresponsive non-muscle invasive bladder cancer (NMIBC) through intravesical (VE) administration.
Methods: E7766 was designed and synthesized to optimize the potency of binding to dimerized STING proteins of different genetic isoforms. The compound was extensively and comparatively characterized in a variety of biochemical, molecular and cellular, in vivo, ex vivo, and primary human tumor and cellular studies for potency, mechanisms and translational biomarkers. Novel preclinical models to mimic orthotopic NMIBC and deep lesion metastasis were developed, and co-crystalization with recombinant proteins of genetic variations was performed.
Results: E7766, a novel Macrocycle-Bridged STING Agonist, showed highly specific and potent agonist activity in both human and mouse STING. In human PBMCs, E7766 demonstrated potent and consistent activity across seven tested human STING genotypes (IC50, 0.15-0.79 μM). By contrast, a reference cyclic dinucleotide STING agonist showed weaker potency and substantial variability across genotypes (IC50, 1.88 μM - >50 μM). Co-crystal structures indicated a structural basis for the superior interactions of E7766 with STING proteins compared with conventional cyclic dinucleotide STING agonists. Intravesical administration of E7766 to a preclinical orthotopic mouse bladder cancer model mimicking the BCG-unresponsive NMIBC demonstrated a dose-dependent and curative activity without serious adverse effects. The anti-tumoral activity was associated with a robust induction of IFNβ, CXCL10 and other downstream effectors of STING pathway inside the bladder cavity. In addition, single IT administration of E7766 to a subcutaneous (SC) tumor in mice bearing dual CT26 tumors in liver and SC lesion cured 90% of animals without recurrence for over 8 months. Those tumor-free animals rejected re-challenge of the same tumor cells in the absence of CD8+ T cells or NK cells, indicating the presence of a highly effective immune memory response following treatment with E7766 independent of either cell population alone.
Conclusions: E7766 is a structurally novel and highly potent STING agonist with pan-genotypic activity, demonstrating curative anti-tumoral activity in murine models of BCG-unresponsive NMIBC and of metastatic tumors in deep lesions. Clinical investigation of E7766 is under discussion.

Abstract
BACKGROUND Management of facial paralysis in older patients is controversial. The purpose of this study is to evaluate the impact of increasing age on functioning free muscle transplantation (FFMT). PATIENTS AND METHODS Twenty-nine facial paralysis patients over 50 years old received FFMT. A separate group of patients aged 41-50 years old were included as control. Outcome assessments included use of the SMILE evaluation system for excursion, a cortical adaptation scoring system for brain plasticity, and a subjective satisfaction assessment score. Meta-analysis of literature over the past 50 years was also performed to examine the impact of older age. RESULTS The mean change in excursion movement was 13.39 ± 5.49 mm. Weakest excursion was found in the oldest age group (11.74 ± 4.84 mm, p = .097), in concordance with the meta-analysis. There was significant difference between the three different neurotizers (p = .036). Excursion and satisfaction score were significantly worse in the older cohort with the cross face-nerve graft FFMT. CONCLUSIONS FFMT is a viable option in the elderly patient group but performs weaker in excursion. The choice of neurotizer is dependent on the patient's goals and the suitable age at which the benefits outweigh the risks.
