Abstract
The ability to convert between molecular spin states is of utmost importance in materials chemistry. Förster-type energy transfer is based on dipole-dipole interactions and can therefore theoretically be used to convert between molecular spin states. Here, a molecular dyad that is capable of transferring energy from an excited triplet state to an excited singlet state is presented. The rate of conversion between these states was shown to be 36 times faster than the rate of emission from the isolated triplet state. This dyad provides the first solid proof that Förster-type triplet-to-singlet energy transfer is possible, revealing a method to increase the rate of light extraction from excited triplet states.

Abstract
A total of 1 685 school-age children selected from Hangzhou received lung function testing to evaluate the short-term effects of air pollution on their lung function. The results showed that in every 10 μg/m(3) increase of average concentration of PM(2.5) and PM(10) on the day of the test and the day before the test,peak expiratory flow (PEF) decreased 0.039 (95%CI: 0.012-0.067) L/s and 0.031 (95% CI:0.011-0.051) L/s,respectively. When the average concentration of SO(2) increased 10 μg/m(3) on the day of test and the day prior to the test, PEF and 75% of the forced vital capacity that has not been exhaled (MEF(75)) decreased 0.437 (95%CI: 0.217-0.658) L/s and 0.396 (95%CI: 0.180-0.613) L/s. After being adjusted for NO(2),with every 10 μg/m(3) increase of average concentration of PM(2.5) and PM(10) on the day of the test and the day before the test,PEF and MEF(75) decreased 0.056 (95%CI: 0.028-0.085), 0.053(95%CI: 0.027-0.081) and 0.047 (95%CI: 0.026-0.068) L/s,0.044 (95%CI: 0.023-0.065) L/s on the day before the test, respectively. The results indicate that air pollution have short-term and lag effects on lung function of school-age children in Hangzhou.

Abstract
Objective: To evaluate the preliminary efficacy and safety of penetrating canaloplasty for treating primary angle-closure glaucoma (PACG). Methods: It is a prospective interventional case series study. Twenty-two patients (24 eyes) with PACG were treated with penetrating canaloplasty (video attached) at the Eye Hospital of Wenzhou Medical University from June 2015 to August 2018. This modified canaloplasty was performed by making a window at the corneal-scleral bed. Aqueous was redirected to the opening of Schlemm's canal after the canaloplasty with intension sutures. Postoperative follow-up was made at 1 day, 7 days, 1 month, 3 months, and 6 months. Surgical success was defined as intraocular pressure (IOP) ≤ 21 mmHg (1 mmHg=0.133 kPa) with glaucoma medication (quantified success) and without any glaucoma medication (complete success). Main outcome measures included IOP, number of medication, surgical success rate, complications, and filtering bleb status. One-way repeated measure ANOVA and rank sum test were used in statistical analysis. Results: Due to the failure of circumferential catheterization of the canal, 4 eyes converted to trabeculectomy. A total of 19 PACG patients (20 eyes) achieved the successful 360-degree catheterization of the canal, including 11 males and 8 females. The mean age was (54±7) years old (range: 41-65 years old), and the mean angle-closure range was (326.3±46.6) degrees. The mean preoperative IOP was (38.0±11.9) mmHg with the median medication number of 3 (range: 2-5). The mean postoperative IOP was (14.5±11.1), (16.1±6.0), (17.7±5.5), (15.7±5.0), and (15.4±3.7) mmHg at 1 day, 7 days, 1 month, 3 months, and 6 months, respectively. There was significant difference in IOP between postoperative and preoperative (all P<0.01). The median medication number (range) was 0 (0-3), 0 (0-2), 0(0-3), 0(0-2), and 0 (0-2) at the 5 time points, respectively. There was significant difference in medication number between postoperative and preoperative (all P<0.01). The quantified success rate was 95%(19/20), and the complete success rate was 90%(18/20) at 6 months. Postoperative complications were observed in 7 eyes (35%) of 20 PACG eyes, including 3 eyes (15%) with hyphema, 2 eyes (10%) with shallow anterior chamber, 1 eye (5%) with Descemet membrane detachment, and 1 eye (5%) with filtration obstruction at the trabeculum ostium. According to the results of slit lamp and ultrasound biomicroscopy examinations, 70% of the eyes (14/20) had no filtering bleb. Eight eyes (40%) with IOP spike were observed. Conclusion: Preliminary study shows penetrating canaloplasty is safe and effective in the treatment of PACG, but needs a longer follow-up. (Chin J Ophthalmol, 2019, 55: 448-453).

Abstract
Preoperative radiation therapy has been regarded as the optional neoadjuvant treatment to decrease local recurrence of rectal cancer in addition to surgery. However, its benefit in survival remained obscure. This study was aimed to measure the efficacy of preoperative radiation therapy for survival in stage II and III rectal cancer patients. Retrospective cohort study used the database of Surveillance, Epidemiology and End Results program of the National Cancer Institute in the United States from 1988 to 2011. A total of 49439 patients diagnosed with primary rectal cancer who underwent surgery were included. Clinicopathological characteristics and rectal cancer-specific survival between surgery alone group and surgery plus preoperative radiation therapy group were compared. Rectal cancer patients in surgery plus preoperative radiation therapy group had significantly better survival than those in surgery alone group (72.70% vs. 66.61%, P < 0.001), as well as stratified by stages (stage II: 77.4% vs. 74.3%, P < 0.001; stage III: 68.3% vs. 58.6%, P < 0.001). However, this beneficial impact was only observed after 2000s (P < 0.001). Multivariate survival analysis revealed that preoperative radiation therapy was an independent predictor for better survival in stage III (hazard ratio, 0.795; 95% CI, 0.753-0.840; P < 0.001), but not in stage II (P = 0.70). Preoperative radiation therapy might bring a better survival in stage II and III rectal cancer patients, but only as an independent predictor for stage III patients. As time progressed, preoperative radiation therapy might yield more profit for stage II and III rectal cancer patients.

Abstract
Epulis is a benign tumor, rarely involves aggressive alveolar bone resorption. This study reported a rare case of rapid growth of pregnancy epulis with extensive alveolar bone destruction and the management of this case. A 24-year old pregnant woman at 35 weeks and 1 day of gestation presented a large asymptomatic nodular mass with severe teeth loosening at the anterior mandibular region for 4 weeks. Radiographic examination showed extensive alveolar bone resorption around the affected teeth to the apical area. After delivery, the patient received an extended resection under general anesthesia. The final histopathological analysis revealed the diagnosis of epulis. In conclusion, the rapid growth of epulis during pregnancy mimicking malignant neoplasm with aggressive alveolar bone destruction was rare and puzzling. In such cases, the histopathological and immunohistochemical examinations are the only effective method to reach the correct diagnosis and clinician should proceed with high precaution.

Abstract
The tumor components of pancreatic ductal adenocarcinoma (PDAC) are composed of immune microenvironment of extracellular matrix, fibroblasts, endothelial cells and immune cells together with a minority of malignant cells. The failure of the therapeutic measures, such as chemotherapy, targeted therapy and immunotherapy, has been linked to the specific immune microenvironment of pancreatic cancer. By analyzing the components of immune microenvironment of pancreatic cancer, the mechanism of various components in pancreatic cancer such as highly immunosuppressive, hypoxic and connective tissue hyperplasia can be clarified. New efforts in single-cell profiling will enable a better understanding of the composition of the microenvironment in primary and metastatic PDAC, as well as an understanding of how the microenvironment may respond to novel therapeutic approaches.

Abstract
Abstract
Background: Tumor infiltrating lymphocytes (TILs) assessed via light microscopy are prognostic and predictive in the early stage and advanced triple negative and HER2-amplified breast cancer (BC). Higher TILs can also identify patients more likely to benefit from anti-PD-1 therapy. In this study we interrogated T cell subsets that comprise high TILs to determine if distinct subpopulations are key mediators of anti-tumor immunity.
Methods: We characterised TILs with a focus on CD3+ T cells in 129 primary and metastatic BC samples using flow cytometry, bulk RNASeq on flow sorted T cell populations, multiplex immunohistochemistry and microdroplet based single cell 3' mRNA sequencing on the 10X Genomics Chromium platform. Cell type specific gene expression signatures were determined from differential expression between putative T cell subpopulations. These signatures were investigated in clinical cohorts, including trial cohorts treated with pembrolizumab.
Results: High TIL Infiltrates consisted primarily of CD3+ T cells, with both CD8 and CD4 populations. Unsupervised clustering of single cell sequencing identified 9 CD8 and CD4 subpopulations with distinct gene expression profiles. In addition to Tregs and CD8 effector memory (TEM) T cells, we found a CD8+ tissue resident memory (TRM) population expressing greater levels of T-cell checkpoints and cytotoxic markers compared to effector memory cells. In 2 primary tumours and 1 liver metastasis, bulk RNASeq of flow sorted TEM and TRM corroborated the single cell mRNASeq results. T cell receptor profiling (TCR) in the 3 samples found non-overlapping repertoires in the 2 primary tumours, but overlap in one metastatic lesion, suggesting divergent developmental origins in the breast, but the potential for nascent TRM differentiation in a metastatic niche. Clustering of these TCRs suggested differing antigen specificities between TRM and non-TRM CD8 T cells. Using Metabric data, the CD8 TRM gene expression signature was prognostic for disease free survival (DFS) in primary TNBCs (n=329, log-rank p=0.003), and was able to further stratify cases with high and low CD8A expression for DFS (log-rank p = 0.03). The CD8 TRM signature was enriched in baseline tumour samples of responders (n = 9) compared with non-responders (n=36) in 45 patients with metastatic melanoma treated with T cell checkpoint blockade (p < 0.0001). Additional single cell sequencing data with TCR sequencing will be combined with these initial results, and an independent data set of single cell mRNASeq and TCR Seq on CD3+ BC TILs will be used to confirm our findings. Cell type specific signatures will be explored in additional clinical cohorts including KEYNOTE-086, and presented at the meeting.
Conclusion: Using single cell profiling of the immune microenvironment in BC we demonstrate that high TIL BCs contain multiple T cell subpopulations with different functional and prognostic significance. Our approach identified a CD8 TRM population with a distinct gene expression profile and strong expression of key immune checkpoints likely representing the presence of true tumor specific immunity. This population may be a key target of immune checkpoint blockade.

Abstract
UNLABELLED Glucocorticoid-induced osteoporosis (GIOP) is common in patients prescribed with long-term glucocorticoids. Guidelines suggest patients receiving moderate-dose glucocorticoid therapy receive GIOP preventive care. Previous studies have shown preventive care rates are not optimal. We look at GIOP preventive care rates in rheumatology patients and predictors of various components of care. PURPOSE Glucocorticoid-induced osteoporosis (GIOP) is a common concern in patients prescribed with long-term glucocorticoids. Studies have shown GIOP preventive care is not provided optimally in the general population; however, little is published on GIOP preventive care among patients with rheumatic disease. The objective of this study is to determine the proportion of rheumatology patients who received GIOP preventive care. METHODS A population-based retrospective quality assurance study of adults seen at the University of Alberta Rheumatology Clinic was performed using the electronic outpatient medical record. Records of adult patients prescribed with prednisone from January 1st to December 31st, 2016 by a rheumatologist were initially included for review. Those who had been prescribed ≥ 7.5 mg/day for ≥ 3 months were assessed for concurrent GIOP preventive care. RESULTS A total of 745 discreet courses of prednisone were prescribed in 433 patients with 113 meeting the above inclusion criteria. Following the prednisone prescription, 79% were taking vitamin D, 86% were taking calcium, and 50% were prescribed with osteoporosis pharmacotherapy. Twenty-five percent of patients had DXA imaging ordered by the rheumatologist within the first 6 months; of these, 86% of patients completed the DXA. CONCLUSIONS Overall, our study shows that patients under the care of rheumatologists receive better GIOP preventative care than previously reported care in the general population. However, there is still room for improvement. In particular, men, younger patients, and rural patients seem to be at the most at risk of not receiving optimal GIOP prevention.

Abstract
UNLABELLED Despite their proven efficacy for secondary fracture prevention, long-term adherence with oral bisphosphonates is poor. INTRODUCTION To compare the effectiveness of two interventions on long-term oral bisphosphonate adherence after an upper extremity fragility fracture. METHODS Community-dwelling participants 50 years or older with upper extremity fragility fractures not previously treated with bisphosphonates were randomized to either a multi-faceted patient and physician educational intervention (the active control arm) vs. a nurse-led case manager (the study arm). Primary outcome was adherence (taking > 80% of prescribed doses) with prescribed oral bisphosphonates at 12 months postfracture between groups; secondary outcomes included rates of primary non-adherence and 24-month adherence. We also compared quality of life between adherent and non-adherent patients. RESULTS By 12 months, adherence with the initially prescribed bisphosphonate was similar (p = 0.96) in both groups: 38/48 (79.2%) in the educational intervention group vs. 66/83 (79.5%) in the case manager arm. By 24 months, adherence rates were 67% (32/48) in the educational intervention group vs. 53% (43/81) in case managed patients (p = 0.13). Primary non-adherence was 6% (11 patients) in the educational intervention group and 12% (21 patients) in the case managed group (p = 0.07). Prior family history of osteoporosis (aOR 2.1, 95% CI 1.0 to 4.4) and being satisfied with current medical care (aOR 2.3, 95% CI 1.1 to 4.8) were associated with better adherence while lower income (aOR 0.2, 95% CI 0.1 to 0.6, for patients with income < $30,000 per annum) was associated with poorer rates of adherence. There were no differences in health-related quality of life scores at baseline or during follow-up between patients who were adherent and those who were not. CONCLUSION While both interventions achieved higher oral bisphosphonate adherence compared to previously reported adherence rates in the general population, primary non-adherence and long-term adherence to bisphosphonates were similar in both arms. Adherence was influenced by family history of osteoporosis, satisfaction with current medical care, and income. TRIAL REGISTRATION ClinicalTrials.gov : NCT01401556.

Abstract
Both live attenuated (HA-L) and inactivated (HA-I) hepatitis A vaccine were licensed for routine use in China. Although phase 1, 2 and 3 clinical studies of both vaccines have been completed, further systematic evaluation of their immunogenicity and immunological persistence under phase 4 clinical studies in a wide range of conditions and involving large populations is necessary. A phase IV clinical trial (NCT02601040) was performed in 9000 participants over 18 months of age. Geometric mean concentrations (GMCs) and seroconversion rates (SRs) were compared at five time points during 3 years for 1800 individuals among them. The SRs of HA-L and HA-I were 98.08% (95% CI 95.59%-99.38%) and 99.64% (95% CI 98.93%-100.00%) respectively 28 days after administration of the first dose, and remained at 97.07% (95% CI 94.31%-98.73%) or above and 96.73% (95% CI 94.07%-98.42%) or above respectively during the following 3 years. The GMCs for both the HA-L and HA-I groups showed that both vaccines elicited high anti-HAV titres, considerably more than the threshold of protection needed against HAV infection in humans, and these titres were sustained. Hence, both HA-I and HA-L vaccines could provide an excellent long-term protective effect, and supported the routine use of both vaccines.

Abstract
To analyze the correlation between transcutaneous oxygen pressure (P(tc)O(2)) and blood lactate in patients with septic shock. Fifty-sixpatients with septic shock were prospectively investigated. P(tc)O(2) was monitored continuously for 6 hours, and arterial blood gas was measured at baseline (T0) and 6 hours(T6). Records of P(tc)O(2),were analyzed for the correlation with lactate level and lactate clearance rate. P(tc)O(2) valuesin the high lactate clearance group and the low one were compared.The lowest value of P(tc)O(2) at T6 and duration of P(tc)O(2)<40 mmHg (1 mmHg=0.133 kPa) were both correlated with lactate level and lactate clearance rateat T6.The low predictive value of P(tc)O(2) was 29 mmHg of lactate clearance under 20% with a sensitivity 85.2% and a specificity 65.5%. The low predictive value of P(tc)O(2) in high lactate clearance group was significantly higher than that in low lactate clearance group, while the duration of P(tc)O(2)<40 mmHg was shorter than the latter. During 6 h continuous monitoring, patients with a significant low P(tc)O(2) or prolonged duration of low P(tc)O(2) have relatively high lactate or low lactate clearance after resuscitation.

Abstract
Vitellogenin (Vg) and its receptor (VgR) play a key role in the reproductive process and development of insects. Aphids are a group of high-fecundity insect species with pseudoplacental viviparity, but the roles of their Vg and VgR genes have not been investigated yet. The brown citrus aphid, Aphis (Toxoptera) citricidus, is a major insect pest of citrus and the main vector of Citrus tristeza closterovirus. In this study, we identified and characterized these two genes, designated as AcVg and AcVgR, from the brown citrus aphid. We found that AcVg has lost the DUF1943 domain that is present in other insect Vgs. Silencing of AcVg and AcVgR led to a delay in the nymph-adult transition, a prolonged prereproductive period, and a shortened reproductive period, which in turn resulted in slower embryonic development and fewer new-born nymphs. Interestingly, silencing of AcVg decreased the transcript level of AcVgR, but silencing of AcVgR resulted in increased transcript levels of AcVg. In addition, silencing of Vg/VgR had similar phenotypes between alate and apterous morphs, suggesting that the functions of these two genes are the same in the two wing morphs of the aphid. Our results demonstrate that Vg and VgR are involved in various aspects of aphid development and reproduction. Further studies on the synthesis of Vg could help to elucidate the reproductive mechanism and provide information that will be useful for developing new pest control strategies.

Abstract
Peptidoglycan is the major bacterial component recognized by the insect immune system. Peptidoglycan recognition proteins (PGRPs) are a family of pattern-recognition receptors that recognize peptidoglycans and modulate innate immune responses. Some PGRPs retain N-acetylmuramoyl-L-alanine amidase (Enzyme Commission number: 3.5.1.28) activity to hydrolyse bacterial peptidoglycans. Others have lost the enzymatic activity and work only as immune receptors. They are all important modulators for innate immunity. Here, we report the cloning and functional analysis of PGRP-S4, a short-form PGRP from the domesticated silkworm, Bombyx mori. The PGRP-S4 gene encodes a protein of 199 amino acids with a signal peptide and a PGRP domain. PGRP-S4 was expressed in the fat body, haemocytes and midgut. Its expression level was significantly induced by bacterial challenges in the midgut. The recombinant PGRP-S4 bound bacteria and different peptidoglycans. In addition, it inhibited bacterial growth and hydrolysed an Escherichia coli peptidoglycan in the presence of Zn2+ . Scanning electron microscopy showed that PGRP-S4 disrupted the bacterial cell surface. PGRP-S4 further increased prophenoloxidase activation caused by peptidoglycans. Taken together, our data suggest that B. mori PGRP-S4 has multiple functions in immunity.

Abstract
BACKGROUND The deposit and adherence of particulate matter (PM) from aerial pollution onto the surface of human hair is a poorly studied phenomenon. OBJECTIVES (i) To reproduce in vitro the deposit of known PM on standardized hair swatches in a closed box, (ii) to compare in vitro data with those obtained under 'real-life' conditions of severe aerial pollution and (iii) to assess the changes of the hair surface properties, potentially caused by the adherence of airborne PM onto the hair. METHODS In vitro: a PM was sprayed onto untreated or sebum-coated hair swatches. Real-life conditions: other swatches were exposed to a severely polluted environment, for 24 to 72 h, in Baoding (PR China). In both cases, swatches were examined using scanning electron microscopy. The shine, the frictional properties and the level of metals were measured and compared to those same properties for the unexposed swatches. RESULTS This work clearly indicates that, under real-life conditions, a large number of PM of various sizes are deposited onto the hair surface. This phenomenon is increased by the presence of sebum and longer exposure times. The in vitro level of PM deposited onto the hair surface is comparable to the in vivo level. The presence of sebum seems to favour the deposit of larger PM. The shine of the exposed swatches is significantly decreased, whereas their respective friction coefficients are significantly increased. Both the presence of sebum and length of exposure time increased the amount of analysed metals present on the exposed hair surface (Al, Fe, Cu, Ba and Zn). CONCLUSION This work indicates that a very high amount (e.g. billions) of PM can be deposited on a full head of hair for subjects living in a severely aerially polluted environment. This process can be reproduced in vitro. In real-life, pollution has a strong impact on hair surface properties, leading to a modification of the visual aspect (loss of shine) and the alteration of hair surface (increase in friction force). This work may be used to pave the way for prevention and cleansing studies in the field of hair care.

Abstract
BACKGROUND AND AIMS Both low birthweight and high birthweight have been associated with the development of cardiometabolic disease in adulthood, possibly reflecting the effect of intrauterine fetal programming. As developmental programming can begin before conception, pre-gravid factors that predict birthweight may be relevant in this context. However, little is known about such factors. Thus, we established a pre-conception cohort to identify maternal pre-gravid cardiometabolic determinants of infant birthweight. METHODS AND RESULTS In this prospective observational cohort study, 1484 newly-married women in Liuyang, China, underwent baseline (pre-gravid) evaluation and then were followed across a subsequent pregnancy. Pre-gravid cardiometabolic characterization consisted of clinical (anthropometry, blood pressure) and biochemical evaluation (total/LDL/HDL cholesterol, triglycerides, glucose) at median 20 weeks before a singleton pregnancy. Mean birthweight was 3294 ± 444 g, with 173 neonates large-for-gestational-age (LGA) and 110 small-for-gestational-age (SGA). On multiple linear regression analysis, positive determinants of birthweight were maternal age, pre-gravid body mass index (BMI), weight gain in pregnancy, length of gestation, and male infant (all p ≤ 0.0003). On logistic regression analysis, independent predictors of an LGA delivery were maternal age (OR = 1.10 per year, 95%CI 1.03-1.18), pre-gravid BMI (OR = 1.21 per kg/m2, 1.07-1.37), and gestational weight gain (OR = 1.10 per kg, 1.06-1.14). The only independent predictor of SGA was gestational weight gain (OR = 0.93 per kg, 0.89-0.97). CONCLUSION Maternal weight before and during pregnancy is the predominant cardiometabolic determinant of infant birthweight, rather than pre-gravid blood pressure, glucose or lipid profile.

Abstract
Hepatitis A virus (HAV) is a highly infectious agent that causes acute liver disease. The infection can trigger the production of antibodies against the structural and non-structural proteins of HAV. Nonetheless, vaccination with an HAV vaccine leads to the production of a primary antibody against the structural proteins. Because the non-structural proteins are only produced during active virus replication, there is no or very little antibody production against the non-structural proteins. However, the current commercial immunoassay cannot distinguish between antibodies produced during natural infection and those from vaccination against HAV. In our study, six immune-dominant epitopes from the non-structural proteins were designed, synthesized, linked together and cloned into pGEX-5X-1 plasmid. The recombinant protein was expressed in E. coli and purified by Ni2+-coated magnetic agarose beads. Then the purified recombinant protein was used as an ELISA antigen to detect antibodies for HAV non-structural proteins in serum samples. Seventy-seven attenuated and 89 inactivated vaccinated samples collected from our previous phase IV study of HAV vaccines were detected by peptide ELISA developed in this study. The mean OD450 value for the vaccination samples and acute infection samples were 0.529 (0.486 for the attenuated group and 0.567 for the inactivated group) and 1.187, respectively. According to the receiver operating characteristic (ROC) curve, the sensitivity and specificity of the peptide ELISA were 93.80% and 91.00%, respectively. This peptide ELISA was confirmed to discriminate vaccine-induced immunity from natural infection of HAV in a phase IV study with high sensitivity and specificity.

Abstract
Objective: To investigate the killing effect of low-temperature plasma (LTP) on HepG2, A549 and HeLa cell lines and explore its possible mechanism. Methods: The inhibitory effect of LTP on the proliferation of HepG2, A549 and HeLa cells was determined by MTT assay. Transmission electron microscopy was used to observe the ultrastructural changes of HepG2, A549 and HeLa cells treated with LTP. Cell apoptosis was detected by Muse cytometry. Western blot was used to detect the expression of apoptosis-related proteins. Results: The survival rates of LTP-irradiated HepG2 cells (irradiated for 107 s), HeLa cells (irradiated for 121 s) and A549 cells (irradiated for 127 s) were 50%. LTP destroyed the ultrastructure of HepG2, A549 and HeLa cells to different degrees, showing nuclear fragmentation and organelle damages. The apoptosis rates of the three cell lines were increased at 24 h after exposure to LTP for 1/6 IC50 irradiation time. Furthermore, LTP irradiation also suppressed the protein expression of Bcl-2 and XRCC1 and increased that of Bax. Conclusions: LTP has an obvious killing effect on HepG2, A549 and HeLa cancer cell lines. This effect may be related to the induction of cell apoptosis and inhibition of DNA repair.

Abstract
BACKGROUND Cardiovascular disease (CVD) accounts for a significant portion of deaths in patients with COPD; however, evidence for early detection strategies for CVD in this population remain limited. Our paper aims to summarize existing data regarding subclinical CVD in patients with COPD with a view to identifying screening strategies in these patients. METHODS A systematic review of published literature was conducted for studies examining the relationship of COPD and markers of subclinical disease such as coronary artery calcification (CAC), carotid intima media thickness (cIMT), endothelial dysfunction, arterial stiffness as measured by pulse wave velocity (PWV) and augmentation indices (AIx). Both MEDLINE and EMBASE databases were searched till October 2015. RESULTS A total of 22 studies were included in the review. Compared with control subjects, patients with COPD had significantly higher cIMT (SMD 0.53, 95% CI 0.16-0.90), PWV (SMD 0.91, 95% CI 0.67-1.16) and AIx (SMD 0.86, 95% CI 0.52-1.19). Additionally, an overall higher prevalence of subclinical CVD as assessed by CAC, ABI and FMD was noted in our review. CONCLUSION Although our findings need further evaluation in prospective studies, our review presents significant evidence in support of increased subclinical CVD burden in COPD patients independent of smoking status. Further large-scale case-control studies are required to highlight the significance of subclinical CVD screening in COPD patients.

Abstract
BACKGROUND As ethnicity is typically recorded as a single demographic variable in clinical studies, little is known about the relative impact of maternal vs. paternal ethnicity on fat distribution. OBJECTIVES The objective of this study was to determine whether there is a differential impact of maternal and paternal ethnicity on infant adiposity. METHODS Three hundred fifty-five infants underwent anthropometric assessment at age 3 months, including skin-fold thickness (SFT) measurement at subscapular, suprailiac and triceps. Maternal (M) and paternal (P) ethnicity were classified as white (M = 241, P = 252), Asian (M = 50, P = 42) or other (M = 64, P = 61). RESULTS Infants with either Asian mother (compared with white) or Asian father (compared with white) had increased subscapular, suprailiac and triceps SFT (all P < 0.05). On logistic regression analysis, however, only maternal Asian ethnicity (compared with white) independently predicted the likelihood of an infant being in the highest tertile for SFT at subscapular (odds ratio [OR] = 2.72, 95% confidence interval 1.17-6.34, P = 0.02), suprailiac (OR = 3.56, 1.51-8.42, P = 0.004) and triceps (OR = 3.26, 1.40-7.55, P = 0.005). In contrast, paternal Asian ethnicity was independently associated with sum of SFT only (OR = 2.46, 1.02-5.97, P = 0.04). CONCLUSION Maternal and paternal Asian ethnicity have differential effects on infant fat distribution. Future clinical studies on obesity and fat composition should consider the distinct contributions of both parents to the ethnic classification of participants.

Abstract
Duloxetine is an effective treatment for oxaliplatin-induced painful chemotherapy-induced peripheral neuropathy (CIPN). However, predictors of duloxetine response have not been adequately explored. The objective of this secondary and exploratory analysis was to identify predictors of duloxetine response in patients with painful oxaliplatin-induced CIPN. Patients (N = 106) with oxaliplatin-induced painful CIPN were randomised to receive duloxetine or placebo. Eligible patients had chronic CIPN pain and an average neuropathic pain score ≥4/10. Duloxetine/placebo dose was 30 mg/day for 7 days, then 60 mg/day for 4 weeks. The Brief Pain Inventory-Short Form and the EORTC QLQ-C30 were used to assess pain and quality of life, respectively. Univariate and multiple logistic regression analyses were performed to identify demographic, physiologic and psychological predictors of duloxetine response. Higher baseline emotional functioning predicted duloxetine response (≥30% reduction in pain; OR 4.036; 95% CI 0.999-16.308; p = 0.050). Based on the results from a multiple logistic regression using patient data from both the duloxetine and placebo treatment arms, duloxetine-treated patients with high emotional functioning are more likely to experience pain reduction (p = 0.026). In patients with painful, oxaliplatin-induced CIPN, emotional functioning may also predict duloxetine response. ClinicalTrials.gov, Identifier NCT00489411.

Abstract
OBJECTIVE After preliminary studies aimed at measuring pertinent biochemical parameters, potentially modified in subjects exposed to bad environmental conditions, a dedicated study was performed in Shanghai city to evaluate the effect of Urban pollution upon human skin and to collect feedback from the volunteers under study. METHODS This study was performed during summer 2008 in two different districts of Shanghai, on 159 local residents: 79 subjects from Xu Jia Hui (a centre Shanghainese area), more exposed to pollution, and 80 subjects from Chong Ming, an agricultural region closely located north of Shanghai (<100 kms) and less exposed to pollution, according to official data. Biochemical parameters were measured on skin, and feedback from volunteers was collected through a graduated 'Likert scale' questionnaire under a point scale (strongly agree, agree, disagree, strongly disagree and none). RESULTS The study demonstrated significant differences in several biochemical parameters measured in Chong Ming area, as compared to Urban area, with an increased ratio of squalene/lipids, a lower level of lactic acid and a better cohesion of stratum corneum. Both sebum excretion rate and sebum casual levels did not differ between the two districts. The volunteer's feedback evidenced a perceived link between pollution and their skin problems. CONCLUSION This study demonstrated a significant impact of the pollution upon the skin status, as illustrated by changes in superficial biochemical parameters and volunteers' perception.

Abstract
Pulmonary histoplasmosis is a granulomatous disease, whose diagnosis is not always easy, as it may simulate metastatic lesions due to similar radiographic findings. We herein report two cases of histoplasmosis with solitary pulmonary nodule in asymptomatic patients with histories of cancer surgeries, whose diagnoses were confirmed by postoperative pathological examinations. Doctors must pay attention to risk factors for immunosuppression such as the histories of chemotherapy, radiotherapy, or malignancy, which may increase chances of developing histoplasmosis. Limited surgical intervention is the treatment of choice for these localized lesions.

Abstract
UNLABELLED Aeromonas hydrophila has been increasingly implicated as the aetiologic agent of various human diseases. Therefore, reliable laboratory detection and identification of this bacterium has become clinically and epidemiologically desirable. We developed a nearly instrument-free, simple molecular method for rapid detection of Aer. hydrophila using a cross-priming amplification (CPA) assay with the desA gene as the target. The desA gene is crucial for the survival and growth of Aer. hydrophila under iron starvation. The results can be visualized as colour changes without opening the reaction tubes. No false-positive results were observed for the 33 non-Aer. hydrophila strains tested to evaluate assay specificity. The limit of detection for Aer. hydrophila was approximately 200 copies of desA per reaction (on reference plasmids) and 5 × 10(3) CFU g(-1) Aer. hydrophila in simulated human stool, which is the same sensitivity as a qPCR assay. The performance of the CPA assay was also evaluated with 100 stool specimens from diarrhoea patients and 40 environmental water samples. In conclusion, the simplicity, cost-effectiveness and nearly instrument-free platform of the CPA assay make it practical for use in primary care facilities and smaller clinical laboratories. SIGNIFICANCE AND IMPACT OF THE STUDY Aeromonas hydrophila is a human pathogen that infects via exposed wounds or ingestion of contaminated water and food. In this study, a CPA-based PCR method was developed for specific, rapid, cost-effective detection of Aer. hydrophila, and the test results could be visualized without opening the reaction tubes. This is the first report on the application of the CPA method for the detection of Aer. hydrophila. This novel method could be practical for use in primary care facilities and smaller clinical laboratories.

Abstract
BACKGROUND Mutations in HBx gene are frequently found in HBV-associated hepatocellular carcinoma (HCC). Activation of hypoxia-inducible factor-1α (HIF-1α) contributes to HCC development and progression. Wild-type HBx has been demonstrated to activate HIF-1α, but the effect of HBx mutations on HIF-1α has not been elucidated. METHODS HBx mutations were identified by gene sequencing in 101 HCC tissues. Representative HBx mutants were cloned and transfected into HCC cells. Expression and activation of HIF-1α were analysed by western blot and luciferase assays, respectively. The relationship between HBx mutants and HIF-1α expression in HCC tissues was also evaluated. RESULTS The dual mutations K130M/V131I enhanced the functionality of HBx as they upregulated the expression and transcriptional activity of HIF-1α. The C-terminal truncations and deletion mutations, however, weakened the ability of HBx to upregulate HIF-1α. Meanwhile, the C-terminus was further found to be essential for the stability and transactivation of HBx. In the HCC tissues, there was a positive association between the HBx mutants and HIF-1α expression. CONCLUSION Different mutations of HBx exert differentiated effects on the functionality of HIF-1α, however, the overall activity of HBx mutants appears to increase the expression and transcriptional activity of HIF-1α.

Abstract
BACKGROUND AND AIM Offspring of women with gestational diabetes (GDM) exhibit an adverse cardiovascular risk factor profile by as early as age 5 years. Recently, maternal glycemia has been associated with epigenetic modification of genes on the fetal side of the placenta, including those encoding emerging risk factors (adiponectin, leptin), suggesting that vascular differences may emerge even earlier in life. Thus, we sought to evaluate cardiovascular risk factors and determinants thereof in 1-year-old infants of women with and without GDM. METHODS AND RESULTS Traditional (glucose, lipids) and emerging (C-reactive protein (CRP), adiponectin, leptin) risk factors were assessed in pregnancy in 104 women with (n = 36) and without GDM (n = 68), and at age 1-year in their offspring. In pregnancy, women with GDM had higher triglycerides (2.49 vs 2.10 mmol/L, p = 0.04) and CRP (5.3 vs 3.6 mg/L, p = 0.03), and lower adiponectin (7.3 vs 8.5 μg/mL, p = 0.04) than did their peers. At age 1-year, however, there were no differences in cardiovascular risk factors (including adiponectin) between the infants of women with and without GDM. Of note, maternal and infant adiponectin levels were associated in the non-GDM group (r = 0.39, p = 0.001) but not in the GDM group (r = 0.07, p = 0.67). Furthermore, on multiple linear regression analyses, maternal adiponectin emerged as an independent predictor of infant adiponectin in the non-GDM group only (beta = 776.1, p = 0.0065). CONCLUSION Infants of women with and without GDM have a similar cardiovascular risk factor profile at age 1-year. However, there are differences in their early-life determinants of adiponectin that may be relevant to the subsequent vascular risk of GDM offspring.

Abstract
AIMS In the Diabetes Control and Complications Trial, mean updated HbA(1c) accounted for most of the differential risk of microvascular complications between intensive and conventional insulin therapy. We hypothesized, however, that a more precise measure of chronic hyperglycaemic exposure may be the incremental area-under-the-HbA(1c)-curve above the Diabetes Control and Complications Trial-standardized normal range for HbA(1c) (iAUC(HbA1c>norm)). METHODS Using the Principal Diabetes Control and Complications Trial data set, we compared the following three measures of chronic glycaemic exposure for their capacity to predict retinopathy, nephropathy and neuropathy during the Diabetes Control and Complications Trial: mean updated HbA(1c), iAUC(HbA1c>norm), and total area-under-the-HbA(1c)-curve (tAUC(HbA1c)). For each outcome, models using each of these three glycaemic measures were compared in the following three ways: hazard or odds ratio, χ(2) statistic, and Akaike information criterion. RESULTS The three glycaemic measures did not differ in their prediction of neuropathy. iAUC(HbA1c>norm) was modestly superior to mean updated HbA(1c) for predicting nephropathy (χ(2) P = 0.017, Akaike P = 0.032). In contrast, for predicting retinopathy, both iAUC(HbA1c>norm) (χ(2) P = 0.0005, Akaike P = 0.0005) and tAUC(HbA1c) (χ(2) P = 0.004, Akaike P = 0.004) were significantly better than mean updated HbA(1c). Varying its HbA(1c) threshold incrementally between 37 and 53 mmol/mol (5.5-7.0%), inclusive, did not improve the prediction of retinopathy by iAUC(HbA1c>threshold) beyond that of tAUC(HbA1c,) consistent with the concept of a continuous relationship between glycaemia and retinopathy, with no glycaemic threshold. CONCLUSIONS Both iAUC(HbA1c>norm) and tAUC(HbA1c) were superior to mean updated HbA(1c) for predicting retinopathy. Optimal assessment of chronic glycaemic exposure as a determinant of retinopathic risk may require consideration of both the degree of hyperglycaemia and its duration.

Abstract
CONTEXT Several previous studies have investigated circulating levels of the adipokine leptin in relation to gestational diabetes mellitus (GDM). However, these studies have yielded markedly conflicting results, including increased, decreased, and unchanged leptin levels in women with GDM as compared with their peers. OBJECTIVE We sought to evaluate the metabolic determinants of serum leptin in a well-characterized cohort reflecting the full spectrum of glucose intolerance in pregnancy. DESIGN, SETTING, AND PARTICIPANTS Metabolic characterization, including oral glucose tolerance test (OGTT) and measurement of serum leptin, insulin, lipids, adiponectin, and C-reactive protein, was performed in 817 pregnant women. The OGTT identified 198 women with GDM, 142 with gestational impaired glucose tolerance, and 477 with normal glucose tolerance. RESULTS Median leptin (ng/ml) did not differ between the normal glucose tolerance (33.7), gestational impaired glucose tolerance (36.3), and GDM (36.4) groups (P = 0.085). On univariate correlation analysis, leptin was most strongly associated with prepregnancy body mass index (BMI) (r = 0.54, P < 0.0001), fasting insulin (r = 0.60, P < 0.0001), and C-reactive protein (r = 0.38, P < 0.0001) but only weakly associated with area under the glucose curve (AUC(glucose)) on the OGTT (r = 0.10, P = 0.0066). On multiple linear regression analysis, the strongest independent determinant of leptin was prepregnancy BMI (t = 11.55, P < 0.0001), whereas AUC(glucose) was not a significant predictor (t = -0.95, P = 0.34). Furthermore, although its respective associations with fasting insulin, triglycerides, and adiponectin varied across tertiles of prepregnancy BMI, leptin was not significantly associated with AUC(glucose) in any BMI tertile. CONCLUSIONS Pregravid BMI, rather than gestational glucose tolerance, is the primary determinant of serum leptin concentration in pregnancy.

Abstract
Alanine aminotransferase (ALT) predicts incident type 2 diabetes (T2DM), possibly reflecting early fatty liver and hepatic insulin resistance. Thiazolidinediones and metformin can improve fatty liver and hepatic insulin resistance, respectively. In the Canadian Normoglycemia Outcome Evaluation trial, rosiglitazone/metformin (Rosi/Met, 4/1000 mg) reduced incident T2DM by 66% in subjects with impaired glucose tolerance. For insight on the hepatic effects of this therapy in relation to T2DM, we evaluated the temporal changes in waist, hepatic insulin sensitivity (1/Homeostasis Model Assessment of Insulin Resistance) and ALT in the Rosi/Met (n = 103) and placebo (n = 104) arms over median of 3.9 years. Waist did not differ between the arms. Hepatic insulin sensitivity improved in the Rosi/Met arm in year 1, but deteriorated thereafter as in the placebo arm. In contrast, Rosi/Met lowered ALT in year 1 and maintained this effect throughout the trial. Thus, low-dose Rosi/Met had no effect on central obesity, a transient effect on hepatic insulin sensitivity, and a sustained effect on ALT.

Abstract
OBJECTIVE The aim of the study is to summarise our experience of endovascular stent grafting for Stanford type A aortic dissection. DESIGN Retrospective analysis at single centre. METHODS From January 2001 to January 2009, we treated 45 cases of Stanford type A aortic dissection with endovascular stent grafting. The entry tear was located at the ascending aorta in 10 cases (DeBakey type I), the aortic arch in 14 cases and the distal aortic arch or proximal descending aorta in 21 cases in which the ascending aorta was also involved by the dissection. RESULTS The surgical success rate was 97.8% (44/45) and 30-day mortality rate was 6.7% (3/45). Type I endoleaks occurred in 10 cases: one patient died intra-operatively, four were successfully treated with ballooning, four were sealed with aortic cuffs and one case caused by left subclavian artery (LSA) reflux was sealed with an occluder. Average follow-up time was 35.5 ± 5.4 months. Up to the most recent review or death, 32 patients had complete thrombosis and 10 had partial thrombosis inside the false lumen. Two deaths occurred after 30-days postoperatively. CONCLUSION Endovascular stent-graft treatment is a minimally invasive and effective method to treat Stanford type A aortic dissection.

Abstract
BACKGROUND Families supporting children with complex needs are significantly more distressed and economically disadvantaged than families of children without disability and delay. What is not known is the associations and costs of parental psychiatric distress within a multi-diagnosis group of special needs children. METHODS In this cross-sectional survey, families were identified from the Children's Treatment Network. Families were eligible if the child was aged 0-19 years, resided in Simcoe/York, and if there were multiple family needs (n = 429). RESULTS Some 42% of surveyed parents exhibited symptoms (mild to severe) of psychiatric distress. The presence of these symptoms was associated with reports of poorer social support, family dysfunction, greater adverse impact of the child's situation on the family, poorer child behaviour, unfavourable parenting styles and poorer child psychosocial functioning. The severity of the child's physical dysfunction was not related to parents/guardians most knowledgeable symptoms of psychiatric distress. Total parent costs were higher and children's uses of primary care services were higher in parents with symptoms of psychiatric distress. CONCLUSION Parent symptoms of psychiatric distress are a significant societal concern in families with complex needs children. Children's rehabilitation efforts need to incorporate parental mental health assessment and treatment into existing programmes. This could lead to decreases in direct and indirect healthcare utilisation costs.

Abstract
ABSTRACTProcessable polymeric nonlinear optical materials can be synthesized by functionalizing a glassy macromolecule with chromophores having large quadratic hyperpolarizabilities, followed by poling in an electric field. In the present case, the functionalization of polystyrene with 4- (4-nitrophenylaza)(N-ethyl)(2-hydroxyethyl))aniline, 4-(4-N,N-dimethylaminostyryl) pyridine, and N-(4-nitrophenyl)-L-prolinol is described. Particularly noteworthy is the high level of chromophore units that can be incorporated into transparent films of these materials, the high second harmonic coefficients that can be achieved (as high as d33 – 11 × 10-9 esu at 1064 nm), and the long-term temporal stability of the second harmonic generation capacity.

Abstract
Oxidative stress and inflammation are involved in the pathogenesis of diabetic endothelial dysfunction. Herein we reported the biological changes induced by hyperglycemia in human umbilical vein endothelial cells (HUVECs) and the potential underlying mechanisms sought to determine whether high glucose concentration or the persistence plays a key role in the development of vascular lesions. The HUVECs were exposed to various glucose concentrations (5, 15, 30, and 60 mmol/L of D-glucose supplemented), and several oxidative stress factors, such as NO, NOS, and ROS, and inflammatory signaling markers, such as TNF-α, TNFR, RIP, TRADD, TRAF-2 and NF-κB, were analyzed at various times (24, 48, 72, and 96 h). High glucose (HG) induced a transient increase of NO within 24 h and decreased afterwards, in accord with the expression of eNOS. HG also increased ROS and TNF-α production and activated the TNF-α-mediated signal transduction, decreasing cell viability and inducing apoptosis. However, 3 HG groups had similar effects on HUVECs with the increased duration of exposure, which resulted in the amplified oxidative and inflammatory damage. Taken together, these findings suggest that the HG persistence exacerbates oxidative stress and activates the inflammatory-mediated signaling pathways, inducing endothelial dysfunction and apoptosis, regardless of the concentration of HG. Our results provide the first evidence that HG persistence is more important than concentration in the progress of diabetic endothelial dysfunction.

Abstract
Heat and moisture transport plays an important role in many engineering areas. In many sweat transport systems, such as clothing assembly, the moisture concentration (or sweat) is relative small and the air concentration reaches a steady state quickly. In this paper, a quasi-steady-state multi-component and multi-phase model for heat and moisture transport in porous textile materials with phase change is proposed. An analytic form of the air concentration is obtained in terms of the mixture gas (vapour and air) concentration and temperature. The new model is described in the form of a single-component flow with an extra air resistance (permeability), involving only the vapour concentration (or pressure), temperature and water content. The existence of the classical positive solutions of the corresponding steady-state model is proved. Two types of clothing assemblies are investigated numerically. The comparisons among the experimental measurements and numerical results of the fully dynamic model, the proposed quasi-steady-state model and steady-state model are also presented. Numerical results show that the proposed quasi-steady-state model is realistic and less complicated.
