Abstract
A novel electric field-magnetic powder coupled membrane bioreactor (EM-MBR) was constructed, which was superior on improvement of phenol treatment performance and sludge characteristics, and mitigation of membrane fouling. EM-MBR enhanced the phenol degradation via the improvement activity of phenol degrading enzymes. The EPS contents and SVI of EM-MBR were significantly reduced by 49.3 % and 58.7 % than that of the conventional MBR, respectively. Moreover, EM-MBR successfully reduced fouling rate by 57.0 %, delaying the membrane resistance. The EPS contents were positively correlated with the SVI and fouling rate, implying that the sludge settleability was strengthened by improving the properties of EPS with the assistance of electromagnetic, thus mitigating the membrane fouling. Microbial co-occurrence network demonstrated that EM-MBR enriched phenol-degrading and EPS-degrading genera correlated to Fe redox cycle. Furthermore, the activation of the antioxidant system in the EM-MBR resulted in the suppression of reactive oxygen species (ROS) generation, consequently impeding the dissemination of antibiotic resistance genes (ARGs). Co-occurrence patterns of MGEs and ARGs revealed that intercellular binding facilitated by ist and Integrase may account for the horizontal transfer of ARGs. The reduction of unit capital costs (15.63 %), running costs (53.00 %), and total average carbon emissions (15.18 %) indicated that EM-MBR was environmentally beneficial.

Abstract
Functional food such as, quinoa, coix seed, wild rice and chickpea have experienced rapidly increasing demand globally and exhibit high economic values. Nevertheless, a method for rapid yet accurate detection of these source components is absent, making it difficult to identify commercially available food with labels indicating the presence of relevant components. In this study, we constructed a real-time quantitative polymerase chain reaction (qPCR) method for rapid detection of quinoa, coix seed, wild rice and chickpea in food to identify the authenticity of such food. Specific primers and probes were designed with 2S albumin genes of quinoa, SAD genes of coix seed, ITS genes of wild rice and CIA-2 genes of chickpea as the target genes. The qPCR method could specifically identify the four wild rice strains, yielding, LODs of 0.96, 1.14, 1.04 and 0.97 pg/µL quinoa, coix seed, wild rice and chickpea source components, respectively. Particularly, the method allowed the identification of the target component with content below 0.01%. A total of 24 commercially available food samples of different types were detected by using the method and the results indicate that the developed method is applicable to the detection of different food matrices, as well as authenticity verification in deeply processed food.

Abstract
UNLABELLED In an Ontario fracture liaison service (FLS), we compared medication prescription rates among patients not taking a previously prescribed bone active medication to those with no previous prescription. Prescription rates were similar between these two groups of patients. The FLS provided a secondary opportunity for patients to initiate bone active medication. PURPOSE We compared bone active medication prescription rates among patients presenting to an Ontario fracture liaison service (FLS) who reported not taking a previously prescribed bone active medication to those with no history of prescription. METHODS Eligible patients were those screened in 39 fracture clinics between July 1, 2017, and September 15, 2019, who were not taking bone active medication at the time of screening and classified as high risk for future fracture based on CAROC or FRAX. Sociodemographic and clinical risk factor variables were assessed at screening. Bone active medication prescription rate was assessed within 6 months of screening and defined as having received a prescription for the medication from either a specialist or primary care provider. In cases where a specialist report was not available, patient self-reported data were collected. The chi-square test of independence was used to assess differences in prescription rates. RESULTS Of 17,575 patients screened, eligible patients were 350 with a previous prescription and 2644 without a previous prescription. Compared with patients who reported no previous prescription, those who had a previous prescription were older, more likely to be female and to report a previous fracture, and less likely to smoke. There was no statistically significant difference between the medication prescription rate of patients with a previous prescription (73.7%) compared to patients with no previous prescription (70.7%) (p = 0.157). CONCLUSION A large jurisdiction-wide FLS approach provided a secondary opportunity to patients who were not taking a previously prescribed bone active medication to initiate that medication.

Abstract
UNLABELLED We examined the demographic characteristics and risk factors of FLS fragility fracture patients who had sustained prior fragility fracture(s) and found that this is an important high-risk subgroup that warrants further attention within FLS priority pathways in order to disrupt their fragility fracture cycle. PURPOSE Our primary objective was to examine whether fragility fracture patients presenting to a provincial fracture liaison service (FLS) having a history of prior fractures, versus those without, differ in demographic characteristics and risk factors for future fracture. A secondary objective was to understand if those who report two or more prior fractures differ from those reporting one prior fracture. METHODS This cohort study included fragility fracture patients aged 50 + enrolled in the Ontario FLS between July 2017 and September 2019. Patients with versus those without prior fractures were compared on age, sex, index fracture site, biological parents' history of hip fracture, current fracture due to a fall, history of feeling unsteady when walking, history of falls in the past year, smoking, oral steroid use, and comorbid chronic conditions. Pearson's chi-square, Fischer's exact, and analysis of variance tests were used to assess differences. RESULTS Among 14,454 patients, 16.8% (n = 2428) reported a history of one or more prior fractures after the age of 40. They were significantly more likely to be older, female, with a higher number of comorbidities, with greater incidence of falls, and feel unsteady when walking. Compared to those with one prior fracture, patients with greater than one prior fracture were more likely to report falls in the past year and feel unsteady when walking. CONCLUSION Findings suggest that FLS fragility fracture patients who had sustained prior fragility fracture are an important high-risk subgroup that warrants further attention within FLS priority pathways in order to disrupt their fragility fracture cycle.

Abstract
Polymerase chain reaction (PCR) technology has become a standard technique for the detection of genetically modified organisms (GMOs). However, this method requires a PCR amplification process which is both expensive and time-consuming. Herein, we propose electric field-induced release and measurement (EFIRM) technology as an alternative method for GMO screening. The specificity and sensitivity of the EFIRM assay were proven to be comparable to those of the real-time PCR method for detecting genetically modified soybeans. After all the parameters had been evaluated, the actual evaluation of soybean samples from soybean cargoes was performed. An actual EFIRM screening was performed on 157 soybean cargo samples, which had 102 transgenic soybean samples containing the GTS-40-3-2 gene, through a blind trial at the Dalian port of China. Our results showed that 101 transgenic soybean samples were correctly detected, with only one false-negative case, and 55 non-transgenic soybean samples were detected as negative; this demonstrates that the EFIRM assay is an effective, accurate, simple, and economical novel method for detecting transgenic products, which may have a positive impact on the development of rapid on-site GMO monitoring platforms.

Abstract
UNLABELLED Among individuals presenting to an Ontario FLS, we compared bone active medication initiation rates of patients 80 years and older with those 50-79 years old. After accounting for fracture risk status, there was no statistically significant difference in medication initiation rates between the two age groups INTRODUCTION: A Fracture Liaison Service (FLS) offers post-fracture services to individuals over the age of 50 years and could potentially address age inequities in pharmacotherapy often observed for older adults. Among individuals presenting to an Ontario FLS and classified as being at high risk for future fracture, our objective was to compare bone active medication initiation rates of patients 80 years and older with those 50-79 years old. METHODS In 39 FLS fracture clinics across Ontario, Canada, fracture prevention coordinators identified, assessed, and facilitated the referral of eligible patients for bone densitometry, fracture risk assessment, and implementation of pharmacotherapy in patients classified as high risk for future fracture. Variables assessed at baseline included age, sex, marital status, living location, fracture location, history of previous fracture, parent's history of hip fracture, history of falls, and fracture risk status. At 6 months, bone active medication initiation was assessed in patients classified as high risk for future fracture. The Chi-square test of independence was used to compare medication initiation rates between patients 80 + and those 50-79 years old. RESULTS Our sample size consisted of 808 patients aged 50-79 years and 346 aged 80 + years. After accounting for fracture risk status, there was no statistically significant difference in medication initiation rates of patients 50-79 and 80 + years old (76.9% versus 73.7%, p = 0.251). CONCLUSION A systematic approach to identifying patients at high risk for future fracture and tailoring treatment recommendations to these patients appeared to eliminate differences in treatment initiation rates based on older age.

Abstract
AIMS Diseases of maricultured species caused by Vibrio harveyi are increasing in China and other regions. This study examined the genetic diversity, antimicrobial susceptibility, plasmid profiles and virulence potential of the V. harveyi isolated from marine organisms farmed in two provinces in eastern China between 2014 and 2019. METHODS AND RESULTS A total of 54 V. harveyi were obtained from seven marine species. Enterobacterial repetitive intergenic consensus (ERIC)-PCR fingerprinting revealed substantial genetic heterogeneity among the V. harveyi isolates. There was no significant correlation between ERIC-PCR genotypes and host origins or fish farms. All the isolates were resistant to amoxicillin and ampicillin, and 79·6% to kanamycin. We found that 61·1% of the V. harveyi isolates had plasmid(s) and there were 14 different plasmid profiles. Most isolates from fish hosts (76·5%) contained plasmids; however, 75% of isolates from nonfish hosts lacked plasmids. Experimental infection results showed that isolates with plasmid(s) were more virulent to large yellow croaker than isolates lacking plasmids (P < 0·05). CONCLUSIONS This study confirmed that V. harveyi isolates obtained from animals farmed in the coastal region of east China were genetically diverse. Our results suggest that the virulence of various V. harveyi strains to fish is associated with the plasmids they carry. SIGNIFICANCE AND IMPACT OF THE STUDY More than 50% of the V. harveyi isolates carried one to 11 plasmids. The plasmid-borne traits of V. harveyi strains might be important for host adaptation and virulence, but they were not associated with susceptibility to the tested antibiotics.

Abstract
Abstract
Logical loops or circular logics, interpreted as circular supporting relations among systems, remain a longstanding challenge in the probabilistic safety assessment (PSA). Logical loops are commonly found in complex industrial systems. Due to the existence of the logical loops, the minimal cut sets cannot be directly obtained. In order to solve this problem, the logical loops should be broken properly. This paper proposes a graphical method based on multi-tree structure. By constructing the simplified multi-tree, logical loops both in linearly and non-linearly interrelated systems are solved. To illustrate this method, examples of linearly interrelated systems and non-linearly interrelated systems are given in this paper. As a supplement, this method is applied to the well-known complex logical loops in the nuclear power plant. It shows that this method is highly intuitive and efficient by means of graphs.

Abstract
Major depressive disorder (MDD) is more common in women than in men, and evidence of gender-related subtypes of depression is emerging. Previously identified blood-based transcriptomic biomarkers distinguished male and female subjects with MDD from those without the disorder. In the present pilot study, we investigated the performance of these biomarkers in pregnant and postpartum women with prior major depressive episodes, some of whom had current symptomatology. The symptom scores of 13 pregnant and 15 postpartum women were identified by the Inventory of Depressive Symptoms (IDS-SR-30) at the time of blood sampling. Blood levels of the 20 transcriptomic biomarkers and that of estrogen receptor 2 (ESR2), membrane progesterone receptor alpha and beta (mPRα, mPRβ) were measured. In pregnant women, transcript levels of ADCY3, ASAH1, ATP11C, CDR2, ESR2, FAM46A, mPRβ, NAGA, RAPH1, TLR7, and ZNF291/SCAPER showed significant association with IDS-SR-30 scores, of which ADCY3, FAM46A, RAPH1, and TLR7 were identified in previous studies for their diagnostic potential for major depression. ASAH1 and ATP11C were previously also identified as potential markers of treatment efficacy. In postpartum women, transcript levels of CAT, CD59, and RAPH1 demonstrated a trend of association with IDS-SR-30 scores. Transcript levels of ADCY3, ATP11C, FAM46A, RAPH1, and ZNF291/SCAPER correlated with ESR2 and mPRβ expressions in pregnant women, whereas these associations only existed for mPRβ in postpartum women. These results suggest that a blood biomarker panel can identify depression symptomatology in pregnant women and that expression of these biomarker genes are affected by estrogen and/or progesterone binding differently during pregnancy and postpartum.

Abstract
DNA methylation is an important epigenetic modification that regulates gene expression in many biological processes, including immune response. In this study, whole-genome bisulfite sequencing (WGBS) was carried out on healthy body wall (HB) and skin ulceration syndrome (SUS) infected body wall (SFB) to gain insights into the epigenetic regulatory mechanism in sea cucumber Apostichopus japonicus. After comparison, a total of 116,522 differentially methylated regions (DMRs) were obtained including 67,269 hyper-methylated and 49,253 hypo-methylated DMRs (p < 0.05, FDR < 0.001). GO enrichment analysis indicated that regulation of DNA-templated transcription (GO: 0006355), where DNA methylation occurred, was the most significant term in the biology process. The integration of methylome and transcriptome analysis revealed that 10,499 DMRs were negatively correlated with 496 differentially expressed genes (DEGs). Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that these DEGs were enriched in the phosphoinositide 3-kinase-protein kinase B (PI3K/Akt)/mammalian target of rapamycin (mTOR) signaling pathway. Interestingly, two serine/threonine-protein kinases, nemo-like kinase (NLK) and mTOR, were highlighted after functional analysis. The variations of methylation in these two genes were associated with SUS infection and immune regulation. They regulated gene expression at different levels and showed interaction during response process. The validation of methylation sites showed high consistency between pyrosequencing and WGBS. WGBS analysis not only revealed the changes of DNA methylation, but also presented important information about the regulation of key genes after SUS infection in A. japonicus.

Abstract
Papillary thyroid carcinoma (PTC) rarely metastasizes to the suprahyoid retropharyngeal lymph nodes (SRPLNs). Studies on SRPLN metastasis from PTC and a description of the dissection of the SRPLNs via the transcervical approach are rare in the literature. In this study, the cases of six patients diagnosed with PTC with SRPLN metastasis, who underwent dissection of the SRPLNs between 2001 and 2017, were reviewed retrospectively. A transcervical approach was applied for exposure and dissection of the SRPLNs in all patients. All patients were successfully treated by transcervical resection of the metastatic SRPLNs. No patient needed a mandibulotomy or presented severe complications. The median duration of follow-up after dissection of the SRPLNs was 83 months. No recurrence of SRPLN metastasis was identified during follow-up, and none of the patients died of the disease. Surgery might be the best treatment for SRPLN metastasis from PTC. The transcervical route to the retropharyngeal space is through three anatomical barriers, including the submandibular gland, the posterior belly of the digastric muscle, and the blood vessels branching from the external carotid artery and internal jugular vein. Surgical removal of metastatic SRPLNs through the transcervical approach was safe and effective.

Abstract
BACKGROUND Reduction of surgeries in axillary has been proved feasible in breast cancer with negative and limited involved axillary lymph nodes. However, for women with a heavy axillary burden, the extent of dissection is still arguable. PATIENTS AND METHODS From a total of 7042 patients with breast cancer who underwent surgical treatments between 2008 and 2014, 692 (9.85%) patients with the axillary staging of N2-3M0 were classified into Level I-II dissection group and Level I-III dissection group. 203 pairs of patients were matched by the propensity score. RESULTS The positive rate of level-III lymph nodes is 62.4% in patients who underwent Level I-III dissection. There are 67 (22.1%) patients who experienced rise in staging from N2 to N3 due to level-III dissection. With a median follow-up of 62.4 months, no significant difference was observed in RFS (P = 0.897), MFS (P = 0.610) and OS (P = 0.755) between level I-II group and level I-III group. The same results were observed in the independent analysis of neoadjuvant and non-neoadjuvant subgroups. The binary regression model showed the positivity of level-III is only associated with involved lymph nodes in level-II. CONCLUSION Additional level-III dissection has a limited impact on survival but still valuable in an accurate stage. The reduction of surgeries in axillary should be treated with discretion in breast cancer patients with a heavy axillary burden.

Abstract
Abstract
Introduction
Telemedicine is increasingly an option for delivery of healthcare services, but its efficacy and acceptability for delivering CBT for insomnia has not been adequately tested. In a randomized controlled non-inferiority trial, we compared face-to-face and telemedicine delivery (via the AASM SleepTM platform) of CBT for insomnia for improving sleep and daytime functioning at post-treatment and 12-week follow-up.
Methods
Sixty-five adults with chronic insomnia (46 women, mean age 47.2 ± 16.3 years) were recruited primarily from insomnia clinics and screened for disqualifying sleep, medical, and mental health disorders. Eligible participants were randomized to 6 sessions of CBT for insomnia delivered face-to-face (n=32) or via AASM SleepTM (n=33). Participants completed self-report measures of insomnia (Insomnia Severity Index, ISI) and daytime functioning (fatigue, depression, anxiety, and overall functioning) at pre-treatment, post-treatment, and 12-week follow-up. The ISI was the primary non-inferiority outcome.
Results
Telemedicine was non-inferior to face-to-face delivery of CBT for insomnia, based on a non-inferiority margin of 4 points on the ISI (β = -0.07, 95% CI -2.28 to 2.14). Compared to pre-treatment, ISI scores improved significantly at post-treatment (β = -9.02, 95% CI -10.56 to -7.47) and at 12-week follow-up (β = -9.34, 95% CI -10.89 to -7.79). Similarly, daytime functioning measures improved from pre- to post-treatment, with sustained improvements at 12-week follow-up. Scores on the fatigue scale were lower in the telemedicine group at both post-treatment (F=4.64, df=1,119, p<.03) and follow-up (F=5.79, df=1,119, p<.02).
Conclusion
Insomnia and daytime functioning improve similarly whether CBT for insomnia is delivered via telemedicine or face-to-face. Telemedicine delivery of CBT for insomnia should be implemented more systematically to improve access to this evidence-based treatment.

Abstract
Abstract
Introduction
CBT for insomnia (CBTI) is effective but a barrier to its widespread use is the lack of evidence-based delivery modalities other than face-to-face. The perception and acceptability of telemedicine for the delivery of CBTI is unknown. We conducted a randomized controlled non-inferiority trial comparing face-to-face (F2F) and telemedicine (via AASM SleepTM) delivery of CBTI. We compared measures of patient satisfaction with treatment and the perception of the therapist’s warmth and skills between F2F and SleepTM.
Methods
Adults with insomnia were recruited from insomnia clinics and the community and screened for sleep, medical, and mental health disorders. Eligible participants were randomized to receive CBTI either via AASM SleepTM or F2F in 6 weekly sessions of 45-60 minutes each. Participants completed the Client Satisfaction Questionnaire (CSQ-8) and The Therapy Evaluation Questionnaire (TEQ) after completing treatment. The CSQ-8 score ranges from 8-32 with high scores indicating greater satisfaction. We also analyzed the two items on the TEQ that assess participants’ perception of therapist’s warmth and skills. Item scores ranged from 1-7, with higher scores indicating greater warmth and skills.
Results
Sixty-five adults with chronic insomnia were recruited primarily from insomnia clinics. Sixty-two participants (41 women, mean age 48.9 ± 15.4 years) completed all 6 sessions of CBTI via F2F (n=32) or via AASM SleepTM (n=30). Independent samples t-tests revealed no significant differences between conditions on patient satisfaction (SleepTM, 28.5 +/-4.2 vs F2F 29.9 +/-2.4, t(-1.5), p=.14), therapist warmth (SleepTM, 6.0 ±1.1 vs F2F, 6.4±0.95, t(-1.4), p=.16), or therapist skills (Sleep TM 6.4 ±1.0 vs F2F, 6.7±0.59, t(-1.5), p=.15).
Conclusion
Our findings suggest no differences in patient satisfaction, perception of therapist’s warmth, or confidence in therapist’s skills between telemedicine (via the AASM SleepTM) and F2F delivery of CBTI. Telemedicine-delivered CBTI should be implemented more widely.

Abstract
Starting from weakly bound Feshbach molecules, we demonstrate a two-photon pathway to the dipolar ground state of bi-alkali molecules that involves only singlet-to-singlet optical transitions. This pathway eliminates the search for a suitable intermediate state with sufficient singlet-triplet mixing and the exploration of its hyperfine structure, as is typical for pathways starting from triplet dominated Feshbach molecules. By selecting a Feshbach state with a stretched singlet hyperfine component and controlling the laser polarizations, we assure coupling to only single hyperfine components of the A^{1}Σ^{+} excited potential and the X^{1}Σ^{+} rovibrational ground state. In this way an ideal three level system is established, even if the hyperfine structure is not resolved. We demonstrate this pathway with ^{6}Li^{40}K molecules, and discuss its application to other important molecular species.

Abstract
This work details the usage of EFIRM® (Electric Field Induced Release and Measurement) for PCR-free rapid electrochemical detection of mitochondrial DNA. EFIRM® was able to perform highly sensitive detection of animal species for meat contamination testing without multistep sample lysis, DNA extraction, or PCR amplification steps, demonstrating the capability to detect the presence of foreign meat species that only constituted 0.1% of the total mass of a food sample (achieving sensitivity equivalent to that of PCR). The EFIRM® strategy utilizes surface immobilized nucleic acid probes that complement to mitochondrial sequence of Ovis Aries, Sus Scrofa, and Bos Taurus and are immobilized in a polypyrrole matrix on a 96-electrode array. Quantification was performed through amperometric measurement of oxidation-reduction reactions on a streptavidin-peroxidase enzyme chain that completes the nucleic acid complex. All electrochemical procedures were performed using a high-throughput potentiostat system that allows parallelized electrochemical measurement and interfacing to the 96-electrode array.

Abstract
BACKGROUND The BIOCHIP is a novel multiplex indirect immunofluorescence technique used in the serological diagnosis of bullous pemphigoid and pemphigus. The BIOCHIP method combines the screening of autoantibodies and target antigen-specific substrates in a single miniature incubation field. OBJECTIVE To evaluate the diagnostic accuracy of the new immunofluorescence BIOCHIP multiplex tool in pemphigus and bullous pemphigoid. METHODS For the validation of the BIOCHIP, sera from patients with BP (n = 38), PF (n = 8) and pemphigus vulgaris (PV) (n = 23) were used. In addition, sera from disease control patients (n = 63) and healthy volunteers (n = 39) were used. The multiplex BIOCHIP and direct immunofluorescence (DIF) were performed for all BP, PF and PV patients. Additional indirect immunofluorescence (IIF) was performed on patients with BP, and ELISA was performed on patients with pemphigus. RESULTS The BIOCHIP mosaic showed a sensitivity of 86.8% and specificity of 85% for BP180 or BP230 being positive in BP. It demonstrated a sensitivity of 75% and specificity of 97.7% for Dsg1 in PF. The BIOCHIP was found to have a sensitivity of 60.9% and specificity of 73.6% for Dsg3 in PV. CONCLUSION The BIOCHIP mosaic-based immunofluorescence test is potentially a simple, time and effort saving test that can aid in the diagnosis and screening of BP, PV and PF. However, there is potential for interpretation bias and a learning curve that needs to be taken into consideration.

Abstract
BACKGROUND The purpose of this study was to explore the correlation of anxiety and depression with therapeutic response to etanercept in psoriasis patients. PATIENTS AND METHODS One hundred and thirty-three patients with moderate-to-severe plaque psoriasis undergoing etanercept treatment were consecutively enrolled in this prospective cohort study, with all patients receiving etanercept treatment for 6 months. Psoriasis Area and Severity Index (PASI) score was evaluated at baseline (M0) and at month 1 (M1), M3 and M6 after treatment, and PASI 75/90 responses were calculated. The Hospital Anxiety and Depression Scale-Anxiety (HADS-A) score and the HADS-Depression (HADS-D) score were used to evaluate patients' anxiety and depression at M0, M1, M3 and M6. Sustained anxiety/depression were defined as HADS-A/D score≥8points both at M0 and M1. RESULTS Female gender and higher PASI score were associated with high risk of anxiety, while female gender, higher PASI score and longer disease duration were correlated with increased depression risk. After 6 months of etanercept treatment, 65.4% and 36.1% patients achieved PASI 75 and PASI 90 responses respectively, and both HADS-A and HADS-D scores were decreased. Most importantly, no correlation of baseline anxiety and depression with PASI 75 or PASI 90 response after 6 months of treatment was noted, while sustained depression, though not sustained anxiety, was observed to be correlated with decreased PASI 75 and PASI 90 responses. CONCLUSIONS Etanercept reduces anxiety and depression in psoriasis patients, and sustained depression correlates with reduced therapeutic response to etanercept.

Abstract
Given the comparable strains of high-risk human papillomavirus (HPV) present in a subset of Barrett's dysplasia and esophageal adenocarcinoma as in head and neck squamous cell carcinomas and the anatomical proximity of both lesions, we hypothesized that oral sex may increase the risk of Barrett's dysplasia/esophageal adenocarcinoma. Therefore, we compared the sexual behavior of patients with Barrett's dysplasia/esophageal adenocarcinoma and controls (hospital, reflux, and Barrett's metaplasia) to explore a plausible mechanism of viral transmission to the lower esophagus. A hospital-based case-control study involving 36 Barrett's dysplasia/esophageal adenocarcinoma subjects and 55 controls with known HPV DNA status and markers of transcriptional activity i.e p16INK4A and E6/E7 mRNA of the esophageal epithelium was conducted to evaluate differences in sexual history (if any). Barrett's dysplasia/esophageal adenocarcinoma patients were more likely than controls to be positive for HPV DNA (18 of 36, 50% vs. 6/55, 11%, p for trend <0.0001), be male (P = 0.001) and in a relationship (P = 0.02). Viral genotypes identified were HPV 16 (n = 14), 18 (n = 2), 11 (n = 1) and 6 (n = 1). HPV exposure conferred a significantly higher risk for Barrett's dysplasia/esophageal adenocarcinoma as compared with hospital/reflux/Barrett's metaplasia controls (OR = 6.8, 95% CI: 2.1-23.1, adjusted P = 0.002). On univariate analysis, ≥6 lifetime oral sex partners were significantly associated with dysplastic Barrett's esophagus and adenocarcinoma (OR, 4.0; 95% CI: 1.2-13.7, P = 0.046). After adjustment for confounders, HPV exposure and men with ≥2 lifetime sexual partners were at significant risk for Barrett's dysplasia/esophageal adenocarcinoma. If these initial findings can be confirmed in larger studies, it could lead to effective prevention strategies in combating some of the exponential increase in the incidence of esophageal adenocarcinoma in the West.

Abstract
OBJECTIVES Prediction of embolic events (EEs) in infective endocarditis (IE) could inform clinical decisions, such as surgical timing. We conducted a systematic review to more precisely define associations between risk factors and EEs. METHODS We searched two bibliographic databases (1994-2018) for observational studies that reported EEs in IE patients and considered clinical, microbiological or echocardiographic risk factors. Studies that did not use Duke criteria or only investigated a subset of IE patients were excluded. Study quality was assessed using the Newcastle-Ottawa scale. A pooled risk ratio (RR) for each risk factor was estimated using random-effects models; statistical heterogeneity was estimated using I2. RESULTS Of 3862 unique citations, 47 cohort studies (11 215 IE cases) were included; 54 risk factors were analysed in at least two studies, with nine studies reporting other individual factors. Most studies were of high methodological quality. Major predictors of EEs were intravenous drug use (RR 1.69, 95% CI 1.32-2.17; I2 = 46%), Staphylococcus aureus infection (RR 1.64, 95% CI 1.45-1.86, I2 = 32%), mitral valve vegetation (RR 1.24, 95% CI 1.11-1.37, I2 = 30%), and vegetation size >10 mm (RR 1.87, 95% CI 1.57-2.21, I2 = 48%). EE risk was also higher with human immunodeficiency virus, chronic liver disease, elevated C-reactive protein, Staphylococcus spp. infection, vegetation presence, and multiple, mobile or prosthetic mechanical valve vegetation, and lower with Streptococcus spp. infection. Most findings were unchanged in sensitivity analyses that removed studies with pulmonary EEs from the outcome. CONCLUSIONS Given the serious consequences of embolism, surgical evaluation may be considered in patients with these risk factors.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that mediate mRNA degradation or translation repression. Previous study showed that the expression of miRNAs was significantly changed in the body wall of sea cucumber Apostichopus japonicus after skin ulceration syndrome (SUS) infection, which is a dynamic process. However, the critical miRNAs from body wall that involved in different infection stages of SUS remain unknown. In this study, four cDNA libraries were constructed with the body wall from healthy and three SUS-infected stages of A. japonicus. A total of 248 conserved miRNAs and five novel miRNAs were identified through Illumina HiSeq 2000 platform. Compared to the control, 238 miRNAs showed significant differential expression at three stages of SUS progression. Totally, 3149 miRNA-mRNA pairs were identified by target prediction and 314 miRNA-mRNA pairs showed negative correlation. It is noteworthy that 15 miRNAs and four mRNAs were located at the crucial positions of the network built with the anti-correlated miRNA-mRNA pairs. GO and KEGG enrichment analysis indicated that the predicted targets were involved in many immune-related processes. Deep analysis of miR-31c-5p, miR-29b-3p, NF-kB, mucin 2 and titin showed that they may play important roles in the pathogens attachment and recognition, signaling transduction and lesions repair of A. japonicus after SUS infection. These results would be useful for further investigating the potential roles of critical miRNAs and mRNAs in A. japonicus immune regulation.

Abstract
BACKGROUND Pneumocystis jirovecii pneumonia (PJP) affected 5%-15% of solid organ transplant (SOT) recipients prior to universal prophylaxis, classically with trimethoprim-sulfamethoxazole (TMP-SMX). Guidelines generally recommend 6-12 months of prophylaxis post-SOT, yet optimal duration and robust PJP risk stratification have not been established. METHODS A retrospective, single-center, case-control study of PJP among SOT recipients from January 1998 to December 2013 was conducted. Cases had positive PJ direct fluorescent antibody assay of respiratory specimens. Controls were matched 4:1 by nearest date of SOT. Univariate testing and multivariate logistic regressions were performed. RESULTS Fifteen cases were identified among 5505 SOT recipients (0.27% rate) and analyzed vs 60 controls. PJP occurred on average 6.1 years (range 0.9-13.8) post-SOT; no case was receiving PJP prophylaxis at diagnosis. Most were treated with reduced immunosuppression and TMP-SMX plus steroids (80%). Six patients (40%) required critical care; 3 (20%) died. There were no significant demographic differences, though cases tended to be older at SOT (54 vs 48 years, P = .1). In univariate analysis, prior viral infection was more common among cases (67% vs 37%, P = .08). Lower absolute lymphocyte count (ALC) at diagnosis date was strongly associated with PJP (400 vs 1230 × 106 cells/μL, P < .001); odds of infection were high with ALC ≤ 500 × 106 cells (OR 18.7, P < .01). CONCLUSION Pneumocystis jirovecii pneumonia is a rare, late complication of SOT with significant morbidity and mortality. Severe lymphopenia may be useful in identifying SOT recipients who warrant continued or reinstated PJP prophylaxis.

Abstract
Abstract
BACKGROUND:
Approximately 15% of newly diagnosed breast cancers are classified as triple negative (TNBC). TNBCs are considered more aggressive and have a worse prognosis as no targeted therapies are currently available. These tumors are routinely treated with chemotherapy agents with only modest proven efficacy.
Temozolomide (TMZ) is an oral chemotherapy agent commonly used for the treatment of brain tumors and melanoma. TMZ is an alkylating agent, and its therapeutic benefit depends on its ability to alkylate/methylate DNA, most commonly at the N-7 or O-6 positions of guanine residues. This process leads to DNA damage and subsequently triggers cell death. Cells that express the enzyme O6-Methylguanine-DNA Methyltransferase (MGMT) are able to repair damage caused by TMZ. Tumors that lack expression of MGMT, owing to methylation of the gene promoter, demonstrate a better response to TMZ treatment as a result of synthetic lethality.
It was first reported in 2012 that TNBCs were more likely to be MGMT methylated, which was confirmed by another group that reported up to 64% of wild-type BRCA1 TNBC exhibited MGMT gene methylation. In 2013 it was found that basal-like breast cancers were more likely to be MGMT methylated and linked to larger tumor size. Together these findings suggest that a sub-population of TNBCs lack MGMT expression, due to promoter methylation.
Currently, TMZ is not a treatment option for breast cancers given the modest efficacy of TMZ noted in breast cancer clinical trials; however, most of these trials have focused on using this agent to either treat or prevent brain metastases, due to TMZs ability to cross the blood-brain barrier. Importantly, none of these trials investigated MGMT expression or specifically TNBC populations.
We hypothesize that TMZ may be a viable and efficacious treatment option for TNBCs that lack MGMT expression, due to promoter methylation.
METHODS:
We analyzed 12 archival specimens and 4 TNBC cell lines (HTB132, HTB26, HTB126 and HCC1806) for MGMT expression using a qRT-PCR clinical assay available from Calgary Laboratory Services. Additionally, we also looked at MGMT protein expression in the cell lines using Western Blot analysis to confirm the qRT-PCR results. Finally, we performed an in vitro assay with TNBC cell lines to determine cytotoxicity of TMZ.
RESULTS:
Analysis of the archival specimens found that 33% of samples analyzed had MGMT promoter methylation by qRT-PCR. Additionally, we found that HTB26 and HTB126 cell lines showed MGMT promoter methylation by qRT-pCR analysis. Western Blot analysis confirmed lack of MGMT expression in these two cell lines, and also identified another cell line (HCC1806) lacking MGMT protein that was classified as unmethylated by the qRT-PCR clinical assay. Moreover, our in vitro assay found that two cell lines (HTB26 and HCC1806) showed a noticeable response to treatment with TMZ. Interestingly, HTB126 did not show response to TMZ, suggesting that there may be another putative resistance pathway.
CONCLUSIONS:
Preliminary findings suggest that TMZ may be a viable targeted treatment option for TNBCs. Currently, we are investigating drug response using in vivo mouse models, as well as investigating synergistic combination therapy options.

Abstract
In order to preliminarily illustrate the functional differences of phenoloxidases (POs) in Apostichopus japonicus, the full-length cDNAs of two POs (named as AjPOⅡ and AjPOⅢ, respectively) were cloned from the coelomocytes of A. japonicus using 3'- and 5'-rapid amplification of cDNA ends method, and combined with the previously acquired full-length cDNA of a laccase-type PO from A. japonicus (Accession No. KF040052, named as AjPOⅠ), the sequence structure and phylogenic status of POs from A. japonicus (AjPOs) were comparatively analyzed, and the transcriptional expression of AjPOs in different tissues, at different developmental stages and after different bacterial challenges was determined with quantitative real-time PCR method. Sequence analysis indicated AjPOⅡ and AjPOⅢ were both laccase-type POs, coincident to the results of phylogenic analysis. Sequence analysis also showed that AjPOⅠ had a transmembrane domain (J. Jiang et al., 2014), AjPOⅡ contained a signal peptide, and AjPOⅢ possessed a signal peptide and a transmembrane domain, implying that three AjPOs might play different roles in immune and physiological processes. Transcriptional expression analysis showed that AjPOⅡ and AjPOⅢ were most abundant in tube feet, while AjPOⅠhad the highest expression level in coelomocytes (J. Jiang et al., 2014), suggesting that AjPOⅠ may be mainly involved in immune response, while AjPOⅡ and AjPOⅢ are probably responsible for other physiological processes in addition to immune response. Besides, three AjPOs were determined to have different expression patterns during organism development and different spectrums of response against bacteria, which further indicated that there might be immune and physiological functional differentiation among three AjPOs.

Abstract
BACKGROUND Metal exposure and tobacco smoking have been independently associated with diabetes, but no study has been conducted to investigate the interaction between them on the risk of diabetes. AIMS To investigate the effect of occupational exposure to metals, and potential effect modification by smoking, on the risk of diabetes and prediabetes in a cohort of Chinese male workers. METHODS We assessed metal exposure and tobacco smoking at baseline in the Jinchang Cohort of male workers. We used Poisson regression analyses to estimate the interaction between smoking and metal exposures based on occupations, which we grouped according to the measured urinary metal levels. RESULTS Among the 26008 study subjects, compared with non-smokers, the adjusted prevalence ratio (PR) for diabetes was 1.8 [95% confidence interval (CI) 1.3-2.4] for smokers of >40 pack-years. The adjusted PRs were 1.2 (95% CI 1.1-1.4) among mining/production workers and 2.7 (95% CI 2.4-3.0) among smelting/refining workers, both compared with office workers. There was significant effect modification under the additive model between smoking and metal exposure on the prevalence of diabetes (Pinteraction = 0.001), with an adjusted PR of 3.6 (95% CI 2.4-5.4) for those with >40 pack-years of smoking who had the highest metal exposures, whereas no significant interaction was observed for prediabetes. CONCLUSIONS Both exposure to metals and heavy smoking were associated with an increased prevalence of diabetes in this large cohort of male workers. There was also strong interaction between these two exposures in affecting diabetes risk that should be confirmed in future studies.

Abstract
In order to preliminarily understand the immune difference between females and males in the sea cucumber Apostichopus japonicus, the activities assay of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), phenoloxidase (PO), acid phosphatase (ACP) and alkaline phosphatase (ALP) with biochemical methods, the detection of PO isozymes with native-PAGE and catechol staining, and the test of antibacterial activities with bacterial growth curve determination method were performed in this study using cell-free coelomic fluid (CCF) and coelomocyte lysate supernatant (CLS) from females and males as the samples. The PO activities were not detected in the CLS and showed no significant difference between the CCF from females and males. However, totally five PO isozyme bands were detected in the CLS of females while only four were detected in the CLS of males after zymogram analysis. These results implied that the PO isozymes in the coelomocytes of viripotent A. japonicus were inactive under natural condition and may be activated by some certain treatments during native-PAGE, and PO might play different immune and physiological roles between females and males. In addition, the activities of SOD, CAT, POD and ALP in the CCF and the activities of CAT, POD, ACP and ALP in the CLS from males were all significantly higher than those from females. The results collectively suggested that in viripotent A. japonicus, the gender had a remarkable effect on the immunity, and the immunocompetence of males might have an advantage over that of females. Furthermore, the activities of all determined enzymes except PO and the number of detected PO isozymes showed higher values in CLS than in CCF, implying that in viripotent A. japonicus, the coelomocytes might take more immune responsibility in comparison with CCF.

Abstract
Oak wilt caused by Ceratocystis fagacearum is a significant disease of Quercus spp. in the eastern United States. Early and accurate detection of the pathogen is particularly important when disease control is planned. Nested and real-time polymerase chain reaction (PCR) methods utilizing fungal DNA extracted from sapwood drill shavings of red, bur, and white oak at different stages of disease development were compared with culture-based detection from sapwood. The pathogen was detected in all (n = 3) actively wilting branches of each of nine red oak trees using all three methods. The lowest detection rate (33% of assayed branches; 6 of 8 trees) for actively wilting branches was found for white oak using isolation while nested PCR had a branch detection rate of 100% (8 of 8 trees) and real-time PCR of 87% (8 of 8 trees) for the same samples. For both bur and white oak, the pathogen was not detected by isolation in branches over 1 year after their death but was detected using both PCR methods. Only the PCR assays detected the fungus in sapwood samples underlying remnants of sporulation mats (n = 21; 90%, nested and 62%, real-time) on red oak. These PCR methods offer several significant improvements for laboratory-based detection methods of C. fagacearum.

Abstract
To inform the benefit-risk assessment of nivolumab in patients with advanced melanoma, analyses of efficacy and safety exposure-response (E-R) relationships were conducted with data from patients with advanced melanoma enrolled in two clinical studies (phase I and phase III) who received nivolumab 0.1-10.0 mg/kg every 2 weeks. E-R efficacy analyses were performed by relating the nivolumab time-averaged concentration after the first dose (Cavg1 ) to two endpoints: RECIST objective response (OR) and overall survival (OS). E-R safety analyses characterized the relationship between nivolumab Cavg1 and the hazard of all-causality adverse events leading to discontinuation or death (AE-DC/D). Nivolumab exposure represented by Cavg1 was not a significant predictor of OR, OS, or the hazard of AE-DC/D. E-R efficacy and safety relationships were relatively flat over the exposure range.

Abstract
Protein content and globulin subunit composition of soybean seeds affect the quality of soy foods. In this proteomic study, the protein profile of soybean seeds with high (∼45.5%) or low (∼38.6%) protein content and with or without the glycinin (11S) subunit 11SA4 was examined. 44 unique proteins and their homologues were identified and showed that both protein content and 11SA4 influenced the abundance of a number of proteins. The absence of 11SA4 exerted a greater impact than the protein content, and led to a decreased abundance of glycinin G2/A2B1 and G5/A5A4B3 subunits, which resulted in lower total 11S with a concomitant higher total β-conglycinin (7S). Low protein content was associated with higher glycinin G3/A1aB1b and lower glycinin G4/A5A4B3. Using the proteomic approach, it was demonstrated that 11SA4 deficiency induced compensatory accumulation of 7S globulins and led to a similar total abundance for 7S+11S irrespective of protein content or 11SA4.
