Abstract
OBJECTIVE Metabolic disorders and inflammation of chondrocytes are major pathological changes in aging cells and osteoarthritis (OA). Recent studies demonstrated age-related mitochondrial dysfunction may be a key contributing factor in the development of OA. Mitofusin 2 (MFN2) is a key regulator of mitochondrial fusion, cell metabolism, autophagy and apoptosis. This study was performed to ascertain whether MFN2 was involved in the aging of chondrocytes and OA. METHODS Metabolic measurements were taken in rat chondrocytes between different ages (3-week, 5-month, 12-month). MFN2 activity was detected in both human and rat chondrocytes during aging and OA. Then, knockdown of MFN2 with small interfering RNA (siRNA) was performed to confirm whether MFN2 contributes to metabolic changes. Lentiviruses were used to establish MFN2-overexpression/knockdown OA models both in vivo and in vitro to confirm whether MFN2 contributes to OA progress. Further, regulatory mechanism of MFN2 was assessed and interaction between MFN2 and PARKIN was performed. RESULTS A metabolic shift to mitochondrial respiration was confirmed in rat chondrocytes during aging. MFN2 expression was elevated in both human and rat chondrocytes during aging and OA. Knockdown of MFN2 with siRNA reversed the age-related metabolic changes in rat chondrocytes. Overexpression of MFN2 exacerbated inflammation and OA progress, while knockdown of MFN2 ameliorated inflammation and OA progress. Further, MFN2 could be ubiquitinated by PARKIN, declined PARKIN expression during aging and OA might result in elevated MFN2 expression. CONCLUSIONS Elevated MFN2 contributes to metabolic changes and inflammation during aging of rat chondrocytes and osteoarthritis.

Abstract
AIM The study was conducted to investigate the effects of dietary Bacillus subtilis (BS) DSM 32315 on the intestinal microbiota composition and metabolites of weaned pigs. METHODS AND RESULTS Sixty-four piglets were allocated to two groups (control and BS), each group including eight replicates with four piglets. Dietary BS DSM 32315 increased (P < 0·05) the abundances of jejunal Leucobacter and Cupriavidus, ileal Thermus, Coprococcus and Bifidobacterium, as well as colonic Succiniclasticum; and increased the concentrations of ileal straight-chain fatty acids, colonic propionate, branched-chain fatty acids (BCFAs), and tyramine, but decreased (P < .05) the colonic indole concentration. The ileal and colonic microbial community structure tended to cluster into two groups. LEfSe analysis identified five microbial biomarkers in jejunum and eight biomarkers in ileum in the BS group, and three biomarkers in colon in the control group. The ileal Bifidobacterium abundance was positively correlated (P < 0·05) with isovalerate concentration, while the colonic Actinobacteria and Lactobacillus abundances were negatively correlated (P < 0·05) with indole concentration. CONCLUSION These findings suggest that dietary supplementation with BS DSM 32315 could alter the diversity, composition, and metabolites of intestinal microbiota in weaned piglets. SIGNIFICANCE AND IMPACT OF THE STUDY Weaned piglets are often accompanied with impaired gastrointestinal tract and intestinal disorder affecting their growth. This study demonstrated that dietary BS DSM 32315 presented a beneficial role in gut health via regulating intestinal microbiota composition and metabolites.

Abstract
OBJECTIVES To assess the effects of electroacupuncture (EA) at the Zusanli (ST36), Guanyuan (CV4), Zhongwan (CV12), and Fenglong (ST40) acupoints on sirtuin 1 (SIRT1) and glucose transporter type 4 (GLUT4) expression in high-fat diet (HFD)-induced insulin-resistant (IR) rats. METHODS Wistar rats were divided into normal control (NC), HFD, and HFD+EA groups. NC rats were fed a standard chow diet and did not receive EA. After being fed an HFD for eight weeks, rats in the HFD+EA group received EA at 2 Hz five times a week for eight weeks. Rats in the HFD group did not receive EA. RESULTS In HFD-induced IR rats, EA inhibited body weight increase and water intake, which were observed in HFD rats. EA had no effect on fasting blood glucose and postprandial blood sugar levels. Intraperitoneal insulin tolerance testing revealed that EA enhanced insulin sensitivity in HFD-induced IR rats. Compared with NC rats, SIRT1 and GLUT4 were downregulated in the quadriceps femoris of HFD-fed rats but were increased after eight weeks of EA stimulation. CONCLUSIONS EA enhanced HFD-induced insulin resistance by activating SIRT1 and GLUT4 in the quadriceps femoris. These results provide powerful evidence supporting the beneficial effects of EA on HFD-induced insulin resistance.

Abstract
Background:Weight, dietary patterns, vitamin D, physical activity and grip strength have been suggested to be associated with bone loss in older adults. However, studies have yet been performed to investigate the associations between these factors and radial bone microarchitecture.Objectives:This study aimed to describe the associations of weight, dietary patterns, serum 25-hydroxyvitamin D (25(OH)D) concentrations, physical activity and grip strength with bone measures in older adults.Methods:Cross-sectional data on 201 older adults (mean age 72 years, female 46%) from a population-based cohort study were analysed. Weight, dietary patterns, serum 25(OH)D concentrations, physical activity (steps per day), grip strength were collected and analysed from baseline to 10-year follow-up. Areal bone mineral density (aBMD) at spine, hip and whole body were measured by dual-energy X-ray absorptiometry (DXA). Radial cortical and trabecular bone microarchitectures were measured by high-resolution peripheral computed tomography (HRpQCT). Multivariable linear regression was used to analyse associations of study factors with bone measures.Results:Weight was positively associated with radial bone area (total: β=0.18, 95% CI: 0.07, 0.29; cortical: β=0.12, 95% CI: 0.03, 0.21; trabecular: β=0.18, 95% CI: 0.05, 0.32), and was inversely associated with compact cortical volumetric bone mineral density (vBMD) (β= -0.19, 95% CI: -0.37, -0.01) and trabecular thickness (β= -0.25, 95% CI: -0.43, -0.07). Ten-year changes in weight were not significantly associated with bone measures, apart from radial trabecular separation (β= 0.15, 95%CI: 0.009, 0.28). Western dietary pattern scores were inversely associated with radial vBMD (total: β= -0.17, 95% CI: -0.32, -0.01; cortical: β= -0.19, 95% CI: -0.34, -0.04; compact cortical: β= -0.19, 95% CI: -0.34, -0.04; outer transitional zone: β= -0.20, 95% CI: -0.35, -0.06), and were positively associated with cortical porosity (cortical: β= 0.18, 95% CI: 0.03, 0.33; compact cortical: β= 0.19, 95% CI: 0.04, 0.34; outer transitional zone: β= 0.20, 95% CI: 0.06, 0.35). Steps per day were not significantly associated with bone measures, apart from inner transitional zone area and thickness (β= 0.12, 95% CI: 0.003, 0.24; β= 0.19, 95% CI: 0.05, 0.33). Healthy food pattern scores, serum 25(OH)D and grip strength were not significantly associated with radial HRpQCT measures.Conclusion:Higher weight, but not weight change, was beneficial for radial cortical and trabecular bone area but also associated with worse compact cortical vBMD and trabecular thickness. Higher western dietary pattern scores had adverse effects on radial vBMD and cortical porosity while physical activity had inconsistent associations.Disclosure of Interests:None declared

Abstract
Abstract
Introduction
Poor sleep quality may be attributed to several occupational factors and has been linked to adverse health outcomes, including cardiovascular disease. Recent epidemiologic studies suggest rest-activity circadian rhythm (RAR) as a possible determinant of poor sleep quality. The focus of these studies has been on the magnitude of the parameters of RAR with little attention to the impact of their day-to-day fluctuation. We examined association of daily variation in parameters of RAR with sleep quality.
Methods
Participants (n=280) were officers from the Buffalo Cardio-metabolic Occupational Police Stress Study (2004-2009). Sleep quality was determined using the Pittsburgh Sleep Quality Index (PSQI). Participants wore wrist actigraph for a minimum of seven days. A cosine curve was fit to measure goodness of fit and estimate the mean values of the three parameters of RAR: Mesor, Amplitude, and Acrophase. Day-to-day variability of the parameters were assessed by fitting the cosine function separately for each day and computing the sample standard deviation across the days. Poisson regression models were conducted adjusting for demographic, lifestyle, and occupational factors.
Results
The prevalence of poor sleep quality was 50.3%. Poor sleep quality was 56% higher in officers with the largest day-to-day variability in Mesor (PR=1.56, 95%CI:1.11 - 2.19) compared to those with the lowest daily variation. Similar estimates were found for Amplitude (PR=1.42, 1.03 - 1.95), Acrophase (PR=1.86, 1.29 - 2.67), and measure of goodness of fit (PR=1.54, 1.13 - 2.11). On the other hand, mean values of RAR parameters were not significantly associated with poor sleep quality.
Conclusion
Results suggest larger daily variation in parameters of RAR is associated with a decrease in sleep quality. Given that day-to-day variation in RAR may increase the odds of poor sleep quality, future studies ought to address risk factors for higher daily fluctuations in RAR which could aid in developing intervention measures.

Abstract
Abstract
Introduction
Restless legs syndrome (RLS), an under-recognized sensorimotor condition worldwide, is thought to be a prodromal symptom of Parkinson’s disease as suggested by previous evidences. However, its association with prodromal chemosensory impairments, including olfactory or taste dysfunction, has remained largely unknown. Few studies of small sample sizes were conducted in predominantly Caucasian populations and results were inconsistent.
Methods
We performed a cross-sectional analysis including 90,337 Chinese adults free of neurodegenerative diseases in the Kailuan study in 2016. Presence of RLS was defined using revised RLS diagnostic criteria and further verified by Cambridge-Hopkins questionnaire for RLS. Perceived olfactory and taste dysfunction was collected via a questionnaire. The association between RLS and perceived olfactory and taste dysfunction was assessed using logistic regression model, adjusting for potential cofounders such as age, sex, smoking, alcohol consumption sleep conditions and medical history.
Results
RLS was associated with high odds of having perceived olfactory and/or taste dysfunction (adjusted odds ratio =5.92; 95% confidence interval, 3.11, 11.3). The significant association persisted when using Cambridge-Hopkins questionnaire for RLS (adjusted odds ratio =5.55; 95% confidence interval, 2.37-13.0) or when excluding participants with major chronic diseases.
Conclusion
RLS was associated with increased odds of perceived olfactory and taste dysfunction.

Abstract
BACKGROUND AND PURPOSE Recent advances in molecular techniques have characterized distinct subtypes of diffuse intrinsic pontine gliomas. Our aim was the identification of MR imaging correlates of these subtypes. MATERIALS AND METHODS Initial MRIs from subjects with diffuse intrinsic pontine gliomas recruited for a prospective clinical trial before treatment were analyzed. Retrospective imaging analyses included FLAIR/T2 tumor volume, tumor volume enhancing, the presence of cyst and/or necrosis, median, mean, mode, skewness, kurtosis of ADC tumor volume based on FLAIR, and enhancement at baseline. Molecular subgroups based on EGFR and MGMT mutations were established. Histone mutations were also determined (H3F3A, HIST1H3B, HIST1H3C). Univariate Cox proportional hazards regression was used to test the association of imaging predictors with overall and progression-free survival. Wilcoxon rank sum, Kruskal-Wallis, and Fisher exact tests were used to compare imaging measures among groups. RESULTS Fifty patients had biopsy and MR imaging. The median age at trial registration was 6 years (range, 3.3-17.5 years); 52% were female. On the basis of immunohistochemical results, 48 patients were assigned to 1 of 4 subgroups: 28 in MGMT-/epidermal growth factor receptor (EGFR)-, 14 in MGMT-/EGFR+, 3 in MGMT+/EGFR-, and 3 in MGMT+/EGFR+. Twenty-three patients had histone mutations in H3F3A, 8 in HIST1H3B, and 3 in HIST1H3C. Enhancing tumor volume was near-significantly different across molecular subgroups (P = .04), after accounting for the false discovery rate. Tumor volume enhancing, median, mode, skewness, and kurtosis ADC T2-FLAIR/T2 were significantly different (P ≤ .048) between patients with H3F3A and HIST1H3B/C mutations. CONCLUSIONS MR imaging features including enhancement and ADC histogram parameters are correlated with molecular subgroups and mutations in children with diffuse intrinsic pontine gliomas.

Abstract
Objective To evaluate whether dihydrotanshinone I (DHTS1) attenuates cuprizone-induced demyelination. Methods DHTS1 was dissolved in 5 g/L sodium carboxymethyl cellulose (CMC-Na). The cuprizone model was induced via feeding with the diet containing 2 g/L cuprizone. We administrated DHTS1 to the cuprizone-exposed mice. The mice were randomly divided into CMC-Na normal group, CMC-Na combined with cuprizone group and DHTS1 combined with cuprizone group. Myelin degeneration was checked by Luxol fast blue (LFB) staining and the immunohistochemical staining of myelin basic protein (MBP) and myelin proteolipid (PLP). Cell apoptosis was measured by TUNEL. Microglia polarization was evaluated by Iba-1, CD86 and CD163 immunohistochemical staining in vivo. The SIM-A9 cells cultured were divided into CMC-Na group, DHTS1 group, CMC-Na combined with LPS group and DHTS1 combined with LPS group. The expression of CD16/32, tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS) was analyzed by flow cytometry in vitro. Results Compared with CMC-Na combined with cuprizone group, DHTS1 treatment significantly attenuated myelin loss and cell apoptosis, reduced the area of Iba-1+ amoebic microglia and the number of CD86+ cells, while increased the number of CD163+ cells in the corpus callosum area of the brain. In addition, compared with CMC-Na combined with LPS group, DHTS1 obviously decreased the percentages of CD16/32+, iNOS+, TNF-α+ microglia. Conclusion DHTS1 can suppress cuprizone-induced demyelination and cell apoptosis through regulating the microglia polarization and mitigating inflammatory reaction in the central nerve system.

Abstract
Animal models of Parkinson's disease (PD), a chronic and progressive neurodegenerative disease of the central nervous system (CNS), play a key role in investigating the pathogenesis and developing new therapeutic strategies of PD. However, this goal has been limited by certain weaknesses in the available animal models of PD, e.g., induction by either pro-inflammatory or neurotoxic reagents, or they are too time-/effort-consuming. Here, we report a double triggers, nasal induction of a PD mouse model that mimics the clinical, pathological features and pathogenesis of PD by intranasal (i.n.) administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) combined with lipopolysaccharide (LPS). After administration once every three days for 7 consecutive weeks, these mice displayed enhanced motor dysfunction, loss of dopaminergic neurons, α-synuclein accumulation, as well as activation of microglia and astrocytes in the substantia nigra pars compacta compared with mice that were administered MPTP or LPS alone. This study provides a novel and basic research tool for investigating the pathogenesis and therapeutic intervention of PD.

Abstract
Mild traumatic brain injury (mTBI), or concussion, is reported to interfere with cerebral blood flow and microcirculation in patients, but our current understanding is quite limited and the results are often controversial. Here we used longitudinal in vivo two-photon imaging to investigate dynamic changes in cerebral vessels and velocities of red blood cells (RBC) following mTBI. Closed-head mTBI induced using a controlled cortical impact device resulted in a significant reduction of dwell time in a Rotarod test but no significant change in water maze test. Cerebral blood vessels were repeatedly imaged through a thinned skull window at baseline, 0.5, 1, 6 h, and 1 day following mTBI. In both arterioles and capillaries, their diameters and RBC velocities were significantly decreased at 0.5, 1, and 6 h after injury, and recovered in 1 day post-mTBI. In contrast, decreases in the diameter and RBC velocity of venules occurred only in 0.5–1 h after mTBI. We also observed formation and clearance of transient microthrombi in capillaries within 1 h post-mTBI. We concluded that in vivo two-photon imaging is useful for studying earlier alteration of vascular dynamics after mTBI and that mTBI induced reduction of cerebral blood flow, vasospasm, and formation of microthrombi in the acute stage following injury. These changes may contribute to early brain functional deficits of mTBI.

Abstract
Osteoradionecrosis of the mandible (MORN) is one of the most devastating complications caused by radiation therapy in the head and neck region. It is characterized by infection and chronic necrosis of the mandible as the main manifestation. Clinically, MORN-related symptoms include swelling, pain, dysphagia, trismus, masticatory or speech disorders, refractory orocutaneous fistula, bone exposure, and even pathological fracture. MORN has become a challenging clinical problem for oral and maxillofacial surgeons to deal with, but thus far, this problem has not been solved due to the lack of widely accepted treatment algorithms or guidelines. Because of the nonexistence of standardized treatment criteria, most clinical treatment against MORN nowadays is largely based on controversial empirical understandings, while recommendations on post-therapeutic evaluations are scarce. Therefore, to further unify and standardize the diagnosis and treatment of MORN, to decrease the huge waste of medical resources, and ultimately, to improve the wellbeing of the patients, the Chinese Society of Oral and Maxillofacial Surgery (CSOMS) convened an expert panel specialized in MORN from 16 domestic medical colleges and affiliated hospitals to discuss the spectrum of diagnosis and and formulate treatment. In addition, consensus recommendations were also revised with a comprehensive literature review of the previous treatment experiences and research pearls. This 'expert consensus statement on diagnosis and clinical management of MORN' is for clinical reference.

Abstract
Abstract
Background
Inflammatory bowel disease (IBD) first presents in a population as cases of ulcerative colitis (UC) followed by cases of Crohn’s disease (CD). Newly industrialized countries (NIC) show a prallel epidemiology of IBD to highly industrialized countries (HIC) in the previous century; one marker of this is the relative incidence/prevalence rates of UC to CD, which approximates 1 over time.
Aims
Provide evidence for the UC:CD ratio as a proxy for disease penatrance in a population.
Methods
Systematic review of MedLine and Embase for studies reporting incidence or prevalence of UC and CD. Log-linear regression (by region and NIC/HIC [2019 United Nations definitions]) was used to calculate average annual percent change (AAPC) and associated 95% confidence intervals (CI). Data were plotted on an online, interactive map to show trends (link provided).
Results
We extracted data from 218 studies compising population-level data from 69 countries. We found negative AAPCs as the prevalence ratio of UC:CD significantly decreased over time in East Asia, West Asia, North Europe, and South Europe; 6/12 global regions displayed significantly decreasing incidence ratios. No AAPC was found to be significantly increasing (Table 1). When examing HIC/NIC, we found a significant effect of NIC on the UC:CD prevalence ratio after 2000 (AAPC:−3.83;95%CI:−6.28,−1.31) while HIC regions remained stable (AAPC:2.14;95%CI:−1.40,5.82). Looking at all available data, both HICs and NICs show significantly decreasing UC:CD prevalence ratios (HIC:AAPC:−3.72;95% CI:−4.46,−2.97; NIC:AAPC:−2.62;95%CI:−4.13,−1.08).
Conclusions
In some HICs (eg. Canada), the UC:CD incidence ratio was <1 in the earliest available data (1966), explaining the stable AAPC in North America (AAPC:−0.24;95%CI:−1.12,0.65). However, in NICs (eg. Southern Asia), the AAPC is rapidly decreasing (AAPC:−24.68;95%CI:−37.85,−8.71) as areas like Sri Lanka rapidly fall from an incidence ratio of 7.5 (2007) to 2.8 (2012), mimicking trends in IBD epidimeology of HICs in the previous century.

Abstract
Abstract
Background
Common variable immune deficiency (CVID) can be associated with autoimmune manifestations including enteric inflammation and diarrhea. Systemic immunosuppression used in patients with inflammatory bowel disease (IBD) may be associated with increased risk of infection in CVID.
Aims
We report a patient with CVID associated intestinal enteropathy who underwent clinical, endoscopic and histological improvement after treatment with vedolizumab (IgG1 monoclonal antibody to α4β7 integrin), as well as a concurrent systematic review (SR) of the literature.
Methods
Case report and systematic literature review. We searched EMBASE, Medline, Cochrane CENTRAL, clinialtrials.gov, and the International Clinical Trials Registry Platform without language restriction using key words to identify patients with CVID associated enteropathy treated with vedolizumab. Clinical, endoscopic and histological outcomes were extracted and safety data.
Results
A 32-year-old male presented with weight loss, anemia and hypoalbuminemia on a background of chronic diarrhea and recurrent sinus infections. Serology and genetic testing was not consistent with celiac disease. Pan-endoscopy showed complete villous atrophy in the duodenum and biopsies showed and intraepithelial lymphocytosis (IEL) in the duodenum and terminal ileum. CT abdomen showed pan-enteritis with extensive mesenteric lymphadenopathy which were reactive on lymph node excision, as well as bronchiectasis. Pneumococcal vaccination challenge to assess humoral response confirmed CVID. After suboptimal response with steroids and mercaptopurine, treatment was initiated with vedolizumab 300mg IV at weeks 0, 2, and 6, then 8 weekly. This led to normalization of stool frequency, weight gain as well as endoscopic and histological resolution within 6 months of treatment. The SR yielded 101 studies of which 3 case series were identified reporting a total of 7 patients with CVID. In 5 cases there was clinical improvement, 4 reported endoscopic improvement and 3 patients had histologic improvement. No safety concerns associated with vedolizumab were reported.
Conclusions
Vedolizumab, a selective leucocyte inhibitor to the gut, was able to induce either clinical, endoscopic or histological improvement in 8 published cases in the worldwide literature. Prospective studies are needed to determine whether this treatment could be included in the therapeutic armamentarium for this orphan indication.

Abstract
Abstract
Background
Citrobacter rodentium is an enteric murine pathogen used to model the human diarrheal pathogens. Following inoculation, C. rodentium colonizes the mouse cecum where it expands and ultimately spreads to the distal colon. During this process, C. rodentium has to compete with commensal microbes for available nutrients. Moreover, to spread throughout the gut, and infect the intestinal epithelium, C. rodentium has to cross through, and or dwell within the intestinal mucus layer which is composed of the heavily glycosylated protein Muc2. Muc-2 is glycosylated and coated by 5 distinct terminal sugar residues: galactose, N-acetylgalactosamine, N-acetylglucosamine, fucose, and sialic acid. Many commensal microbes have the ability to cleave and free these sugars from the Muc2 protein, releasing them for their own consumption, however pathogens appear to exploit this process. While studies have indicated that C. rodentium uses these terminal sugar residues as a nutritional source, their relative importance in the pathogenic strategy of C. rodentium (and other gut pathogens) remains unclear
Aims
Investigate the role played by mucin sugar residues in controlling C. rodentium pathogenesis
Methods
Deletions of agaW, nagE, mglB, galP, fucK, and nanT were generated on the chromosome of C. rodentium (Strepr) by overlap extension PCR. Growth assays were performed to examine the growth kinetics of mutants C. rodentium in minimal (M9) media supplemented with one of the 5 mucin sugars or M9 with whole mucin as control. Specific pathogen free (SPF) C57BL/6 mice, or germfree C57BL/6 mice were orally gavaged with wildtype C. rodentium (Strepr) or one of ΔagaW, ΔnagE, ΔmglB, ΔgalP, ΔfucK, or ΔnanT strains. Mice were euthanized at 6 days post-infection, and the cecum, colon, and spleen were collected and histologically scored for pathology and intestinal and systemic bacterial burden. Stool samples were collected throughout the 6 days to quantify C. rodentium burdens
Results
Growth assays confirmed that the specific sugar transporter/kinase mutant C. rodentium strains grew normally when placed in media supplemented with whole mucin, or with most sugars, only showing overt defects in growth when solely supplemented with the sugar for which they were impaired. Several of the C. rodentium mutants including ΔnanT showed overt defects in colonization/infection of SPF C57BL/6 mice, but their pathogenesis was normalized in germfree mice, or in mice treated with the antibiotic streptomycin at each day post-infection. These findings indicate that the impact of mucin sugar utilization on C. rodentium virulence is microbiota-dependent
Conclusions
C. rodentium uses mucin sugars as nutrient source in the mouse gut, and an inability to use these sugars impairs their ability to infect their hosts in a microbiota dependent manner

Abstract
Abstract
Background
Patients with inflammatory bowel disease (IBD) suffer a substantial burden of morbidity related to chronic abdominal pain and are susceptible to opioid dependence and abuse that is associated with increased rates of depression, hospitalization, and mortality. While opioid prescription and renewal by a single provider minimizes the long-term risk of misuse, many patients with IBD will seek out care in the emergency department (ED) where short-term, ‘to-go’ use of narcotic analgesia is associated with potential treatment-related complications.
Aims
To assess rates of opioid prescription in IBD patients presenting to the ED and to assess factors associated with opioid use.
Methods
This is a retrospective analysis of cross-sectional data collected in the United States National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2006–2015. We compared a study population of adult IBD patients (International Classification of Diseases ICD-9 555.X, 556.X) ≥18 years discharged from the ED to a control group of patients presenting with non-specific abdominal pain (ICD-9 789.0, 564.1, 536.8). The proportion of patients given opioids in ED and at ED discharge were calculated with relative standard error (RSE), and national level estimates were produced using survey weights. Univariable and multivariable logistic regression was used to evaluate predictors of opioid prescription at discharge, expressed as odds ratios (OR) with 95% confidence intervals (CI).
Results
A total of 767,577 IBD patients were compared to 71,359,257 patients with non-specific abdominal pain. A total of 37.3% (RSE 4.7%) of IBD patients compared to 24.7% (RSE 0.8%) of controls (p<0.01) received an opioid prescription on ED discharge. 49.1% (RSE 5.6%) of IBD patients compared to 37.2% (RSE 0.8%) of patients with non-specific abdominal pain (p=0.02) received an opioid while in ED. Significant predictors of narcotic prescription at discharge in multivariable analysis included: age <50 (OR 6.83 [95% CI: 1.21, 38.48], p=0.03), non-white race (OR 4.73 [95% CI: 1.46, 15.39], p=0.01), and narcotic use in the ED (OR 5.27 [95% CI: 1.96, 14.21], p<0.01).
Conclusions
Nearly 40% of IBD patients were prescribed an opioid at discharge from the ED. This rate is significantly higher than for patients who present with non-specific abdominal pain and younger, non-white IBD patients were disproportionately more likely to receive an opioid prescription. Given the risks associated with on-demand narcotic use in IBD patients, our data highlight a potential gap in care for accessing comprehensive pain management solutions.

Abstract
Abstract
Background
Inflammatory bowel diseases (IBD) are chronic, inflammatory conditions of the intestinal tract. In addition to a complex mixture of genetic, and environmental factors, increased intestinal permeability is also thought to be involved. Despite its diagnostic importance, there is no reliable yet minimally invasive way to measure intestinal permeability in patients and animal models. Currently, most assays involve the detection of orally given sugar molecules in either the urine (MLR method) or the plasma (FITC-dextran). These methods offer only limited accuracy, and do not allow continual tracking of intestinal permeability within the same animal due to the requirement of euthanization. Herein, we describe a novel cytometric-based method using an ingested dietary protein (ovalbumin (OVA)) and flow cytometry. We show our method is reliable, highly sensitive, minimally invasive and allows for the continuous tracking of intestinal permeability within the same individual using small blood volumes.
Aims
To compare the utility of our bead-based method of intestinal permeability measurement to the FITC-Dextran method.
Methods
Wildtype (WT) C57BL/6 mice, and mucin 2-deficient (Muc2-/-) mice (known to suffer a leaky gut) at baseline, or mice given chemical or infection-induced colitis were gavaged with a solution containing OVA protein and FITC-Dextran. After 6 hours, mice were euthanized to collect plasma for spectrophotometry (FITC-Dextran), or for flow cytometry (bead-based ELISA) analyses.
Results
We found that both OVA and FITC-dextran were detectable in plasma samples of the Muc2-/- mice, but not the WT mice, 6 hours after oral co-administration, however the bead-based method produced more consistent readings. Immunostaining of tissue sections with the same antibodies also showed that OVA can readily diffuse through the gut epithelium of Muc2-/- mice but not the WT mice, validating the specificity of the antibodies. We also tested our assay on WT mice undergoing dextran sodium sulfate (DSS) colitis, or infected with Citrobacter rodentium. We found that our method could detect statically significant changes in intestinal permeability 2 to 3 days earlier than the FITC-dextran method, while providing greatly reduced variability between technical repeats. More importantly, we were able to use a small volume (5 μL) of whole blood collected via tail poke, to measure intestinal permeability without requiring euthanization of the mice. This allowed the continuous tracking of permeability changes within the same animal.
Conclusions
We conclude that the bead-based method is more sensitive and reliable than the FITC-Dextran method as tested in several murine colitis models. More importantly, we showed that the bead-based method allows continual tracking of intestinal permeability within the same animal, enabling time course measurements.

Abstract
Objective: To explore the clinical application effects of portable visual retractor in superficial temporal fascia flap harvesting. Methods: From January 2010 to June 2019, 27 patients meeting the inclusion criteria and planning to perform operation of superficial temporal fascia flap harvesting were admitted to the Department of Plastic and Reconstructive Surgery of the First Clinical Medical Center of the People's Liberation Army General Hospital. The patients were divided into traditional surgical method group [6 males and 3 females, aged (34±14) years], cold light source retractor group [6 males and 4 females, aged (35±16) years], and portable visual retractor group [7 males and 1 female, aged (30±14) years] according to way of superficial temporal fascia flap harvesting. The superficial temporal fascia flaps of patients in traditional surgical method group were resected by traditional way of resection, and the superficial temporal fascia flaps of patients in cold light source retractor group and portable visual retractor group were resected at assistance of cold light source retractor and portable visual retractor, respectively. Length of incision, operation time, intraoperative blood loss volume, postoperative drainage volume, and postoperative complication of patients in 3 groups were observed and recorded. Data were processed with Fisher's exact probability test, one-way analysis of variance, least significant difference test, Kruskal-Wallis H test, and Bonferroni correction. Results: The length of incision of patients in visual retractor group was (3.6±0.8) cm, significantly shorter than (12.6±1.6) cm in traditional surgical method group and (5.8±0.9) cm in cold light source retractor group (P<0.05). The incision length of patients in traditional surgical method group was significantly longer than that in cold light source retractor group (P<0.05). The operation time of patients in visual retractor group was 24.0 (23.3, 25.8) min, significantly shorter than 35.0 (30.5, 36.5) min in traditional surgical method group and 28.5 (26.8, 30.5) min in cold light source retractor group (H=16.5, 9.8, P<0.05). The operation time of patients in traditional surgical method group was significantly longer than that in cold light source retractor group (H=6.6, P<0.05). The intraoperative blood loss volume was (26±3) mL of patients in visual retractor group, significantly less than (34±4) mL in traditional surgical method group and (30±6) mL in cold light source retractor group (P<0.05). The intraoperative blood loss volume of patients in traditional surgical method group was significantly more than that in cold light source retractor group (P<0.05). The postoperative drainage volumes of patients in visual retractor group, cold light source retractor group, and traditional surgical method group were (33±4), (34±6), and (31±7) mL, respectively, and there were no significantly statistical differences in postoperative drainage volumes among patients in the three groups (F=0.3, P>0.05). There were no severe complications such as ischemia and necrosis of superficial temporal fascia flaps in patients of the three groups. One patient in cold light source retractor group had subcutaneous hematoma after operation, which was improved by removing stitches and hematoma. Conclusions: Superficial temporal fascia flap harvesting at the assistance of portable visual retractor has the advantages of clear visual field, simple operation, short operation time, small incision, and less intraoperative blood loss.

Abstract
Whether third‐generation hydroxyethyl starch solutions provoke kidney injury or haemostatic abnormalities in patients having cardiac surgery remains unclear. We tested the hypotheses that intra‐operative administration of a third‐generation starch does not worsen postoperative kidney function or haemostasis in cardiac surgical patients compared with human albumin 5%. This triple‐blind, non‐inferiority, clinical trial randomly allocated patients aged 40–85 who underwent elective aortic valve replacement, with or without coronary artery bypass grafting, to plasma volume replacement with 6% starch 130/0.4 vs. 5% human albumin. Our primary outcome was postoperative urinary neutrophil gelatinase‐associated lipocalin concentrations, a sensitive and early marker of postoperative kidney injury. Secondarily, we evaluated urinary interleukin‐18; acute kidney injury using creatinine RIFLE criteria, coagulation measures, platelet count and function. Non‐inferiority (delta 15%) was assessed with correction for multiple comparisons. We enrolled 141 patients (69 starch, 72 albumin) as planned. Results of the primary analysis demonstrated that postoperative urine neutrophil gelatinase‐associated lipocalin (median (IQR [range])) was slightly lower with hydroxyethyl starch (5 (1–68 [0–996]) ng.ml−1) vs. albumin (5 (2–74 [0–1604]) ng.ml−1), although not non‐inferior [ratio of geometric means (95%CI) 0.91 (0.57, 1.44); p = 0.15] due to higher than expected variability. Urine interleukin‐18 concentrations were reduced, but interleukin‐18 and kidney injury were again not non‐inferior. Of 11 individual coagulation measures, platelet count and function, nine were non‐inferior to albumin. Two remaining measures, thromboelastographic R value and arachidonic acid‐induced platelet aggregation, were clinically similar but with wide confidence intervals. Starch administration during cardiac surgery produced similar observed effects on postoperative kidney function, coagulation, platelet count and platelet function compared with albumin, though greater than expected variability and wide confidence intervals precluded the conclusion of non‐inferiority. Long‐term mortality and kidney function appeared similar between starch and albumin.

Abstract
Microglial activation-induced neuroinflammation is closely associated with the development of Parkinson disease (PD). Macroautophagy/autophagy regulates many biological processes, but the role of autophagy in microglial activation during PD development remains largely unclear. In this study, we showed that deletion of microglial Atg5 caused PD-like symptoms in mice, characterized by impairment in motor coordination and cognitive learning, loss of tyrosine hydroxylase (TH) neurons, enhancement of neuroinflammation and reduction in dopamine levels in the striatum. Mechanistically, we found that inhibition of autophagy led to NLRP3 (NLR family pyrin domain containing 3) inflammasome activation via PDE10A (phosphodiesterase 10A)-cyclic adenosine monophosphate (cAMP) signaling in microglia, and the sequential upregulation of downstream IL1B/IL-1β in turn increased the expression of MIF (macrophage migration inhibitory factor [glycosylation-inhibiting factor]), a pro-inflammatory cytokine. Inhibition of NLRP3 inflammasome activation by administration of MCC950, a specific inhibitor for NLRP3, decreased MIF expression and neuroinflammatory levels, and rescued the loss of TH neurons in the substantial nigra (SN). Interestingly, we found that serum MIF levels in PD patients were significantly elevated. Taken together, our results reveal an important role of autophagy in microglial activation-driven PD-like symptoms, thus providing potential targets for the clinical treatment of PD.

Abstract
Objective: To assess the vaccine loss related to the Expanded Program on Immunization (EPI) in Xinjiang Uygur Autonomous Region so as to improve the management of vaccines. Methods: A total of 135 vaccination clinics were randomly selected, using a stratified cluster sampling method. In each clinic, data on vaccination was collected between 2016 and 2017, including the number of doses in routine immunization program and supplementary immunization activities (i.e., vaccine doses in vials that were opened for use) on polio vaccine, number of doses administered to children and the number of doses discarded (e.g., expired vaccine or broken vials that had not been opened for use), etc. Coefficient on vaccine loss was calculated with the following equation: vaccine loss coefficient=(number of vaccine doses used)/(number of vaccine doses administered). The vaccine discard rate appeared as: number of vaccine doses discarded)/number of vaccine doses used. Results: For vaccines in single-dose vials [diphtheria-tetanus-pertussis vaccine (DTaP) and trivalent oral polio virus vaccine (tOPV)], the loss coefficients appeared as 1.00 and 1.02, respectively. For vaccines in multi-dose vials [bivalent oral polio vaccine (bOPV), group A meningococcal polysaccharide vaccine (MPV-A), diphtheria-tetanus combined vaccine (DT) and bacilli Calmette-Guérin (BCG) vaccine], the loss coefficients were 1.58, 1.67, 1.68, and 3.02, respectively. The coefficients of EPI vaccine loss in urban, rural, and pastoral area vaccination clinics ranged between 1.00-2.84, 1.00-3.71, and 1.00-2.27, respectively. Loss coefficients ranged between 1.00-3.00, 1.00- 4.41, and 1.00-1.94, respectively, were seen in township clinics, village clinics, and decentralized vaccination clinics. Coefficients on larger vaccine loss were associated with longer intervals between clinic sessions and with fewer vaccinations administrations per day. Conclusions: In Xinjiang, coefficients on the loss of multi-dose EPI vaccines were high. The coefficients on loss were different from the levels of region and types of clinics, and time interval between clinic sessions. Programs on refining the management and distribution of EPI vaccines, to minimize the vaccine loss were recommended.

Abstract
AIM Trends in surgical rates for Crohn's disease (CD) in the biological era are controversial. We aim to assess modern trends in the formation rates of surgical stomas. METHOD Population-based surveillance in the Calgary Health Zone (CHZ), Canada, was conducted between 1 April 2002 and 31 March 2011, using the Discharge Abstract Database to identify adult patients with CD admitted to hospital and treated with surgical stoma formation (n = 545). Annual stoma incidence was calculated by dividing the number of incident stomas by the prevalence of CD in the CHZ. Time trend analysis of the stoma-formation rate was performed, expressed as annual percentage change (APC) with 95% CI. Stoma-formation rates were stratified according to procedure (emergency vs elective) and duration of stoma [temporary (reversed within 2 years of formation) vs permanent]. RESULTS The overall rate of stoma formation between 2002 and 2011 showed a downwards trend, of a mean of 5.2% (95% CI: -8.5 to -1.8) per year, from a rate of 2.30 stomas/100 person-years (PY) in 2002 to 1.51 stomas/100 PY in 2011. The rate of emergency stoma formation decreased significantly from 2002 to 2011 (mean APC = -9.4%; 95% CI: -15.6 to -2.8), while the rate of elective ostomies essentially showed no change (mean APC = -0.9%; 95% CI: -5.3 to 3.8). The rate of temporary stoma formation decreased significantly, by 4.6% (95% CI: -7.3 to -1.8) per year, while permanent stoma formation was stable (APC = 1.0%; 95% CI: -4.0 to +6.3). CONCLUSION A reduction in the overall rate of stoma formation in CD has been driven by fewer emergency stomas, although rates of permanent stoma have remained stable.

Abstract
Motion of the myocardium deteriorates the quality and quantitative accuracy of cardiac PET images. We present a method for MR-based cardiac and respiratory motion correction of cardiac PET data and evaluate its impact on estimation of activity and kinetic parameters in human subjects. Three healthy subjects underwent simultaneous dynamic 18F-FDG PET and MRI on a hybrid PET/MR scanner. A cardiorespiratory motion field was determined for each subject using navigator, tagging and golden-angle radial MR acquisitions. Acquired coincidence events were binned into cardiac and respiratory phases using electrocardiogram and list mode-driven signals, respectively. Dynamic PET images were reconstructed with MR-based motion correction (MC) and without motion correction (NMC). Parametric images of 18F-FDG consumption rates (Ki) were estimated using Patlak's method for both MC and NMC images. MC alleviated motion artifacts in PET images, resulting in improved spatial resolution, improved recovery of activity in the myocardium wall and reduced spillover from the myocardium to the left ventricle cavity. Significantly higher myocardium contrast-to-noise ratio and lower apparent wall thickness were obtained in MC versus NMC images. Likewise, parametric images of Ki calculated with MC data had improved spatial resolution as compared to those obtained with NMC. Consistent with an increase in reconstructed activity concentration in the frames used during kinetic analyses, MC led to the estimation of higher Ki values almost everywhere in the myocardium, with up to 18% increase (mean across subjects) in the septum as compared to NMC. This study shows that MR-based motion correction of cardiac PET results in improved image quality that can benefit both static and dynamic studies.

Abstract
OBJECTIVES To evaluate the effects of China's very recent comprehensive pricing healthcare reform, taking the patients' perspective. STUDY DESIGN Two survey studies were conducted using the same protocol in Beijing in July 2017 and 2018, respectively. METHODS The same questionnaire was used and contains two sections, with the first on demographic and personal information and the second on various assessments of the reform. RESULTS Findings different from those in the government-led evaluations were made. Specifically, the majority of the patients thought the level of medical service fee and cost of medicine still high, and experienced no change or an increase in overall medical cost. The overall assessment of the reform was not sufficiently positive. Multiple problems in healthcare were identified. Development from 2017 to 2018 was not significantly positive. CONCLUSIONS Patients' assessments of the reform were not as positive as those made in the government-led evaluations. In extending the reform to the whole country, the government and healthcare providers may need to further tune the reform to better serve the public.

Abstract
Hyperexcitability of the neural network often occurs after brain injuries or degeneration and is a key pathophysiological feature in certain neurological diseases such as epilepsy, neuropathic pain, and tinnitus. Although the standard approach of pharmacological treatments is to directly suppress the hyperexcitability through reducing excitation or enhancing inhibition, different techniques for stimulating brain activity are often used to treat refractory neurological conditions. However, it is unclear why stimulating brain activity would be effective for controlling hyperexcitability. Recent studies suggest that the pathogenesis in these disorders exhibits a transition from an initial activity loss after acute injury or progressive neurodegeneration to subsequent development of hyperexcitability. This process mimics homeostatic activity regulation and may contribute to developing network hyperexcitability that underlies neurological symptoms. This hypothesis also predicts that stimulating brain activity should be effective in reducing hyperexcitability due to homeostatic activity regulation and in relieving symptoms. Here we review current evidence of homeostatic plasticity in the development of hyperexcitability in some neurological diseases and the effects of brain stimulation. The homeostatic plasticity hypothesis may provide new insights into the pathophysiology of neurological diseases and may guide the use of brain stimulation techniques for treating them.

Abstract
OBJECTIVES The objective of this study to determine whether body mass index (BMI) in different genders and age groups need different thresholds when predicting chronic non-communicable diseases (CNCDs). STUDY DESIGN This is a cross-sectional study. METHODS Data were obtained from the China Health and Nutrition Survey conducted in 2009. Sequential sample cluster analysis was used to group age according to BMI. Propensity score matching was used to eliminate the influence of age. Receiver operating characteristic curve based on gender and age group was used to evaluate the cut-off values and efficiency of BMI in each group. RESULTS A total of 8469 individuals were enrolled in this study. Results of sequential sample cluster analyses showed age was divided into three groups: 18-39, 40-59 and 60-99 years. There were significant differences in the distribution of BMI among the three groups for both males and females (P < 0.001). Statistical differences were observed in the distribution of BMI between genders in the 18-39- and 60-99-year-old age groups (P < 0.001). For men, the cut-off values of BMI were ≥25 kg/m2, ≥24 kg/m2 and ≥23 kg/m2 in the 18-39, 40-59 and 60-99 years old groups, respectively; for women, the corresponding cut-off points were ≥25 kg/m2, ≥23 kg/m2 and ≥25 kg/m2 in groups. CONCLUSIONS The thresholds for BMI might be different between gender and age group. In addition, it might not be suitable to determine cut-off values of BMI to predict CNCDs for people aged ≥60 years.

Abstract
IPW (imprinted gene in the Prader-Willi syndrome region), a long non-coding RNA, is a paternally expressed gene in the PWS/AS imprinted domain on human chromosome 15 and mouse chromosome 7. Disruption of the PWS/AS region is associated with three neurogenic disorders in humans. In this study, we identified the bovine homolog of the IPW gene; multiple transcripts obtained by RT-PCR and RACE showed a complex and tissue-specific expression pattern of IPW in the brain, heart, kidney, liver, lung, spleen and skeletal muscle. An informative single nucleotide polymorphism (rs133341090) in the long exon H was identified by sequencing the genomic DNA, and mono-allelic expression of IPW was confirmed by sequencing the cDNAs of heterozygous individuals, indicating that IPW may be imprinted in cattle. The protein-coding potential of IPW transcripts was assessed using coding potential calculator (cpc) software, which showed a negative score. In addition, sequencing analysis also indicated multiple small open reading frames in the bovine IPW transcript, but none of the ATGs was consistent with Kozak consensus. Taken together, the IPW transcripts are most likely long non-coding RNAs.

Abstract
Aim Intrauterine growth retardation (IUGR) is a prevalent problem in mammals. The present study was conducted to unveil the alterations in intestinal microbiota in IUGR piglets. Methods and Results We identified the alterations of small intestinal microbiota in IUGR piglets on 7, 21 and 28 days of age using 16S rRNA sequencing. The results showed that IUGR piglets had a decreased alpha diversity of jejunum microbiota at 7 and 21 days of age; had lower abundances of Bacteroidetes and Bacteroides in the jejunum at 7, 21 and 28 days of age, Oscillibacter in the jejunum at 21 days of age, and Firmicutes in the ileum at 21 days of age; whereas they had higher abundances of Proteobacteria and Pasteurella in the ileum at 21 days of age and Escherichia–Shigella in the jejunum at 28 days of age. Correlation analysis showed that Bacteroides, Oscillibacter and Ruminococcaceae_UCG‐002 compositions were positively associated with the body weight (BW) of IUGR piglets, nevertheless Proteobacteria and Escherichia–Shigella relative abundances were negatively correlated with the BW of IUGR piglets. Gene function prediction analysis indicated that microbiota‐associated carbohydrate metabolism, lipid metabolism, glycan biosynthesis and metabolism, amino acid metabolism, and xenobiotics biodegradation and metabolism were downregulated in the IUGR piglets compared to control piglets. Conclusions The present study profiled the intestinal microbiota of newborn piglets with IUGR and the newborn IUGR piglets have lower diversity and different taxonomic abundances. Alterations in the abundances of Bacteroidetes, Bacteroides, Proteobacteria Escherichia–Shigella and Pasteurella may be involved in nutrient digestion and absorption, as well as the potential mechanisms connecting to the growth and development of IUGR in mammals. Significance and Impact of the Study The small intestinal microbiota were highly shaped in the IUGR piglets, which might further mediate the growth and development of IUGR piglets; and the gut microbiota could serve as a potential target for IUGR treatment.

Abstract
BACKGROUND AND AIMS The vascular remodeling plays a crucial role in pathogenesis of diabetic cardiovascular complications. In this study, we intended to explore the effects and potential mechanisms of microRNA-24 (miR-24) on vascular remodeling under diabetic conditions. METHODS AND RESULTS MiR-24 recombinant adenovirus (Ad-miR-24-GFP) was used to induce miR-24 overexpression either in carotid arteries or high glucose (HG)-induced vascular smooth muscle cells (VSMCs). Cell proliferation was analyzed using CCK-8 method. Cell migration was examined using wound-healing and transwell assay. mRNA and protein expressions of critical factors were, respectively, measured by real-time PCR and western blot as follows: qRT-PCR for the levels of miR-24, PIK3R1; western blot for the protein levels of PI3K (p85α), Akt, p-Akt, mTOR, p-mTOR, 4E-BP1, p-4E-BP1, p70s6k, p-p70s6k, MMP 2, MMP 9, collagen Ⅰ, as well as collagen Ⅲ. Carotid arteries in diabetic rats suffered balloon injury were harvested and examined by HE, immunohistochemical and Masson trichrome staining. The expression of miR-24 was decreased in HG-stimulated VSMCs and balloon-injured carotid arteries of diabetic rats, accompanied by increased mRNA expression of PIK3R1. The up-regulation of miR-24 suppressed VSMCs proliferation, migration, collagen deposition not only induced by HG in vitro, but also in balloon-injured diabetic rats, which were related to inactivation of PI3K/Akt signaling pathway. CONCLUSION The up-regulation of miR-24 significantly attenuated vascular remodeling both in balloon-injured diabetic rats and HG-stimulated VSMCs via suppression of proliferation, migration and collagen deposition by acting on PIK3R1 gene that modulated the PI3K/Akt/mTOR axes.

Abstract
BACKGROUND The co-existence of underweight and overweight is a great challenge for public health in low-income and middle-income countries (LMICs). OBJECTIVES The objective of the study is to report the prevalence of underweight, overweight and obesity among young adolescents in 58 LMICs. METHODS Data were from the Global School-based Student Health Survey (2007-2013) in 57 LMICs and from the Chinese National Surveys on Students' Constitution and Health (2010). A total of 177 325 young adolescents aged 12-15 years from 58 LMICs were included. Weight status was defined based on both the updated International Obesity Task Force (IOTF) and World Health Organization (WHO) criteria. RESULTS Based on the IOTF/WHO criteria, the overall prevalence of weight categories among young adolescents in LMICs was 13.4%/4.7% for underweight, 15.4%/17.3% for overweight and 5.6%/8.6% for obesity. However, the prevalence varied largely across countries and regions. Based on the IOTF criteria, the prevalence of underweight ranged from 0.0% in Niue to 48.8% in Sri Lanka and obesity ranged from 0.1% in Vanuatu to 35.0% in Niue; a prevalence exceeding 10.0% for both underweight and excess weight (overweight and obesity combined) was found in 29.3% of these countries. Underweight was more prevalent in Southeast Asia and Africa, while obesity was more frequent in Central and South Americas. There were no age and sex differences in the prevalence of weight categories for most countries. CONCLUSIONS Our data confirm the continued dual burden of underweight and overweight in young adolescents in many LMICs and the need for policy and programmes to address both conditions.

Abstract
NEW FINDINGS What is the central question of this study? Oligomeric proanthocyanidin has the capacity to alleviate abnormalities in neurological functioning. However, whether oligomeric proanthocyanidin can reduce the progression of demyelination or promote remyelination in demyelinating diseases remains unknown. What is the main finding and its importance? Oligomeric proanthocyanidin can improve cuprizone-induced demyelination by inhibiting immune cell infiltration, reversing overactivated microglia, decreasing the inflammatory cytokines secreted by inflammatory cells and decreasing the production of myelin oligodendrocyte glycoprotein35-55 -specific antibody in the brain. ABSTRACT Demyelinating diseases of the CNS, including multiple sclerosis, neuromyelitis optica and acute disseminated encephalomylitis, are characterized by recurrent primary demyelination-remyelination and progressive neurodegeneration. In the present study, we investigated the therapeutic effect of oligomeric proanthocyanidin (OPC), the most effective component of grape seed extract, in cuprizone-fed C57BL/6 mice, a classic demyelination-remyelination model. Our results showed that OPC attenuated abnormal behaviour, reduced demyelination and increased expression of myelin basic protein and expression of O4+ oligodendrocytes in the corpus callosum. Oligomeric proanthocyanidin also reduced the numbers of B and T cells, activated microglia in the corpus callosum and inhibited secretion of inflammatory factors. Furthermore, concentrations of myelin oligodendrocyte glycoprotein-specific antibodies were significantly reduced in serum and brain homogenates after OPC treatment. Together, these results demonstrate a potent therapeutic effect for OPC in cuprizone-mediated demyelination and clearly highlight multiple effects of this natural product in attenuating myelin-specific autoantibodies and the inflammatory microenvironment in the brain.

Abstract
Abstract
Introduction
Tailored treatment trials with biomarker-driven hypotheses are becoming an important strategy in drug development. Umbrella, basket and enrichment trials with eligibility predicated upon results of tumor sequencing are increasingly common. Several institutional and commercial genomic assays have been developed. However, the value of broad-based testing in recruiting patients (pts) to molecular-based clinical trials designed for small subgroups has not been fully evaluated and has been challenging to assess in a real-world setting. We evaluated the likelihood of trial enrollment based upon an institute-wide genomic test.
Methods
Since 2013, all pts with metastatic breast cancer (MBC) seen at least once at Dana-Farber Cancer Institute have been offered the option of tumor sequencing using multiplexed copy number variation (CNV) and mts detection across the full coding regions of a total of 447 cancer genes and 191 regions across 60 genes for rearrangement detection (Oncopanel; OP). For our primary analysis, we selected the ongoing multi-center phase II trial (NCT01670877) activated at our site on Sep 30, 2013, evaluating neratinib in ERBB-2 mutated pts, as the study provided a clear delineation of eligible mts, and timing of slot availability was retrievable retrospectively over an extended time frame. Our primary aim was to describe the proportion of pts with a qualifying ERBB-2 mt detected by OP who enrolled on the selected trial. Secondary objectives included median time from OP result to trial registration and description of ERBB-2 mts spectrum within each subtype. Associations were calculated by Fisher's test.
Results
We identified a total of 1,046 pts with HER-2 negative MBC and who had OP results between Sep 1, 2013 and Jun 1, 2017. A total of 43 pts (4.1%) were found to have ERBB-2 mts. Of these, 20 (1.9%) had activating eligible mts. The proportion of these pts who enrolled in the trial was 30% (6/20). Of the remaining 14 pts, 5 screen-failed and 2 were enrolled with known ERBB-2 mt through other testing modalities. Seven of 20 (35%) molecularly eligible pts were not approached (3 pts lost to follow-up, 3 enrolled in other clinical trials and 1 pt chose standard treatment). The median time from OP result to trial enrollment was 85 days (34-554). A significantly higher frequency of ERBB2 activating mts was found in ER+ compared to ER- primary tumors (2.5% vs. 0.3%, p =0.036), and in lobular tumors compared with ductal (5.5% vs. 1.25%, p=0.003). Frequency of eligible mts in primary tumors were similar to metastatic site (1.9% and 1.8%, respectively p=1.0)
Discussion
In this cohort, activating ERBB-2 mts were present in 20 of 1046 (1.9%) pts tested. Although over half of pts with eligible mts on OP testing were approached for NCT01670877, only 0.5% of the total tested population were enrolled (6/1046). Our data illustrate the substantial challenges in screening and enrolling to trials of rare subsets, even within a large academic institution, and point to the need for creative and novel approaches to leverage pts and community- and academic-based providers to more effectively support the success of such studies.

Abstract
Abstract
Background: It is estimated that approximately 46,000 women age >75 are diagnosed annually with breast cancer. Due to competing co-morbidities, there is wide variation in treatment recommendations which can lead to over- or under-treatment. Though surgery for breast cancer is considered low-morbidity, many elderly women given a choice, choose not to have surgery. Previous randomized trials comparing surgery with tamoxifen versus endocrine therapy alone in women age >70 unselected for ER status demonstrated similar overall survival with poorer local control in the latter group. A new standard of care needs to be defined for elderly women with good prognosis ER+ tumors, since these women may benefit from endocrine therapy alone to treat their cancer without compromising local and distant control.
Hypothesis: We hypothesize that endocrine therapy alone provides adequate local and systemic control of breast cancer in a subpopulation of women age 70 or older with ER+ breast cancer and good prognostic characteristics.
Primary Objective
To correlate response to neoadjuvant endocrine treatment at 6 months with Oncotype DX Recurrence Score (RS) in women with early-stage ER+ breast cancer who are age >70.
Secondary Objective
1. To determine the breast cancer-specific survival of women with early-stage ER+ breast cancer, age >70, treated with endocrine therapy alone.
2. To determine the rate of overall survival of women with early-stage ER+ breast cancer, age >70 treated with endocrine therapy alone.
Study Design: This is a prospective single arm phase II study. Patients with clinical stage I/II ER+ breast cancer, grade 1-2, Ki67<30 or RS <18 (performed on the diagnostic core biopsy) continue to be enrolled and followed for time to progression. A Kaplan-Meier model will be used to estimate the 5-year local progression rate. If the true 5-year progression rate is 10%, then 50 patients will provide power = .90 at a one-sided .05 significance level to demonstrate that the rate is less than 25.5%. Exploratory objectives include: evaluation of the molecular characteristics of breast cancers of responders versus non-responders, determine compliance with medications, evaluate cost-effectiveness, and quality of life.
Results: Between February 2017 and April 2018, 11 patients were enrolled into the study. Two patients could not tolerate endocrine therapy and received standard of care treatment. For the 9 patients on study, average tumor size was 1.7cm, average Ki67 was 15%, average RS was 14. All of the patients received an aromatase inhibitor. At 6 months, 71% of the patients had a partial response, 28% had stable disease. None of the patients developed progressive disease.
Conclusion: A new standard of care needs to be defined for women age >70 with good prognosis ER+ tumors, since these women may benefit from endocrine therapy alone to treat their cancer without compromising local and distant control. We continue to enroll patients to determine the optimal tumor markers for identifying women who can be treated with PET only to control their cancer.

Abstract
Abstract
Background: Approximately half of women on aromatase inihbitor (AI) therapy develop AI-induced arthralgia (AIA), and many discontinue the medication because of this common side effect. While Vitamin D has been studied as a treatment for AIA, trial results have been conflicting thus far.
Patients and Methods: All subjects were post menopausal women who were beginning adjuvant AI therapy for stage I-III hormone receptor positive breast cancer. Patients were randomized 1:1 to receive standard dose vitamin D3 (800 IU daily for 52 weeks) or high dose vitamin D3 (50,000 IU weekly for 12 weeks, followed by 2000 IU daily for 40 weeks). All patients also took oral calcium 600 mg daily. The primary endpoint was development of AIA, as defined by pre-specified changes in the Health Assessment Questionnaire II (HAQ-II). Secondary endpoints include compliance with AI therapy, and correlation between grip strength and development of AIA. Exploratory endpoint was measurement of inflammatory cytokine reduction in each arm. The trial was designed to enroll 184 patients, but this futility analysis was performed after 93 patients were enrolled. The futility boundary for stopping the trial early was calculated as p = 0.47.
Results: All 93 patients (46 in the high dose arm, and 47 in the standard dose arm) enrolled in the study at the time of the interim analysis were evaluable. The HAQ-II was completed at 12 weeks in 76% on the high dose arm, and 68% in the standard dose arm. Subjects who did not complete the questionnaire were deemed as study failures (i.e. development of AIA was assumed). In the high dose arm, 25 patients (54%) developed AIA, compared to 27 patients (57%) in the standard dose arm. The one-tailed p value is 0.3818, and the Z-score is 0.3, yielding only a 38% conditional power that that study would find a significant difference between the two arms. Thus, the study was terminated early for futility. There was no significant difference between the two arms in adherence to AI therapy. The grip strength and inflammatory cytokine data are pending at this time. They will be ready by the time of the conference.
Conclusions: There was no significant signal for benefit of high dose vitamin D supplementation, as compared to standard dose vitamin D, for AIA prevention in post menopausal women taking adjuvant AI therapy. These results further characterize the role of Vitamin D in AIA, and they inform future clinical trials in this arena. Further research is necessary, as this remains an important cause of non-adherence to this highly effective therapy.

Abstract
Abstract
Introduction
The PI3K signaling pathway is frequently active in triple negative breast cancer (TNBC), but response to PI3K inhibition is still poorly understood. To gain insights in therapy response and resistance, it is important not only to assess genetic alterations of these tumors, but also their phenotypic characteristics. Furthermore, not only is the functional status of the PI3K pathway important to know, but also other signal transduction pathways that may drive tumor growth, as they may explain primary or acquired therapy resistance.
Material & Method
We analyzed 17 patient derived xenograft (PDX) models of TNBC with varying response to buparlisib treatment. Long-term response (˜30 days) was assessed by comparing growth rates between buparlisib and vehicle treated PDXs. For characterization, mRNA expression analysis was performed on tumor material post 3 days of vehicle or buparlisib treatment of each PDX model. Functional pathway activity was determined using computational Bayesian networks that look at mRNA levels of pathway target genes resulting from activation (Verhaegh et al, Cancer Res 2014), amongst others for the FOXO-PI3K (van Ooijen et al, Am J Pathol, in press), ER, AR, Hedgehog, TGFbeta and Wnt pathways. These computational networks were calibrated on samples with known pathway activity, and biologically validated on various healthy and diseased cell and tissue types.
Results
On an initial set of 6 PDX models, pathway activity clearly varied between different TNBC PDXs, and between vehicle and buparlisib treatment. ER pathway activity was low in all samples, as expected in TNBC. Two PDX models with the most growth reduction by buparlisib showed high PI3K activity, of which one based on low FOXO activity and the other on oxidative stress. The former, best responding PDX showed a clear reduction in PI3K activity (restoring FOXO activity), when comparing 3 days buparlisib to vehicle treatment. Of the two PDX models with least growth reduction, one had low PI3K activity, while the other one, carrying a PIK3CA mutation, did show high PI3K activity (low FOXO), but this remained after treatment.
Other differences in pathway activity that were found, included slightly elevated AR and Wnt activity in one PDX with good response, and somewhat higher TGFbeta activity in four PDXs (good, medium and poor response). Analysis of the remaining 11 PDXs is ongoing, including other signal transduction pathways, to investigate the variation in pathway activity across the entire panel and to shed more light on the differences in tumor biology between the PDX models.
Conclusion
Our computational Bayesian networks measured differences in functional activity of signal transduction pathways across a collection of TNBC PDX models, which may be expected due to the large variation between TNBC tumors. Functional PI3K activity was related to growth inhibition by buparlisib treatment, and reduction of PI3K pathway activity was observed upon treatment in responding PDX models. Other pathways also showed variation across PDXs. Further clinical evaluation of our signal transduction pathway activity measurement is ongoing. RT-qPCR based analysis is available, optimized for FFPE tissue and small samples.

Abstract
Objective: To evaluate the histocompatibility of an original Chinese-made mid-urethral sling (Repelvica mid-urethral sling). Methods: In total 10 female New Zealand white rabbits were implanted with Repelvica mid-urethral sling or tension-free vaginal tape-obturator tape (TVT-O; Gynecare). Both brands of sling were implanted under deep fascia of the abdominal wall and in the space between vagina and bladder. All animal groups were sacrificed at set time intervals (4 weeks and 12 weeks), and the abdominal and vaginal slings were harvested for histological evaluation. Results: All slings appeared to be well incorporated into the abdominal wall and anterior vaginal wall. All specimens showed a thin, loose, fibrous interface between the synthetic graft and abdominal wall or vaginal wall, along with mild inflammatory reaction from 4 weeks to 12 weeks. Abdominal grafts of Repelvica mid-urethral sling and TVT-O induced comparable tissue reaction (histological score 10.5 versus 10.5 at 4 weeks, 10.0 versus 9.5 at 12 weeks; both P>0.05). Vaginal grafts of Repelvica mid-urethral sling had lower histological score than TVT-O (histological score 6.0 versus 12.0 at 4 weeks, 8.5 versus 12.5 at 12 weeks), however the differences were not statistically significant (both P>0.05). Conclusions: Chinese-made Repelvica mid-urethral sling exhibits good histocompatibility. Vaginal graft of Repelvica mid-urethral sling evoks minor tissue reaction, which could be attributed to its lightweighted property and favored its clinical application.
