Abstract
In Ghana, the HIV prevalence among MSM is more than 10 times greater than the general population of adults, and rates of engagement in HIV medical care are low among MSM diagnosed with HIV. Using structured surveys, we investigated the impact of HIV-related stigma, same-sex behavior stigma, and gender nonconformity stigma on linkage to HIV care (LTC) in MSM (N = 225) living with HIV in Ghana. Autonomy-supportive healthcare climate (OR = 1.63, p < .01), vicarious HIV stigma (OR = 2.73, p < .01), and age (OR = 1.06, p < .004) predicted LTC. Conversely, felt normative HIV stigma negatively predicted LTC (OR = 0.65, p < .05). Finally, we identified regional disparities, with MSM from Takoradi being 4 times and 5 times more likely to be LTC compared to Kumasi and Accra, respectively. Our findings highlight the nuanced roles of stigmas in shaping the HIV care continuum among MSM living with HIV, while revealing potential gaps in current measures of HIV-related stigma.

Abstract
PURPOSE Adolescents represent more than half of the newly diagnosed sexually transmitted infections in the U.S. annually. Emergency departments (EDs) may serve as an effective, nontraditional setting to screen for chlamydia/gonorrhea (CT/GC). The objective was to evaluate the effectiveness of a universally offered CT/GC screening program in two pediatric ED settings. METHODS This was a prospective, delayed start pragmatic study conducted over 18 months in two EDs within the same academic institution among ED adolescents aged 14-21 years with any chief complaint. Using a tablet device, adolescents were confidentially informed of CT/GC screening recommendations and were offered screening. If patients agreed to CT/GC testing, a clinical decision support tool was triggered to inform the provider and order testing. The main and key secondary outcomes were the proportion of CT/GC testing and positive CT/GC test results in each respective ED. RESULTS Both EDs experienced modest but statistically significant increases in CT/GC testing post- versus pre-intervention (main: 11.5% vs. 7.9%; confidence interval [CI]: 2.9-4.2; p < .0001 and satellite: 3.8% vs. 2.6%; 95% CI: .7-1.7; p < .0001). Among those tested, the positivity rate at the main ED did not significantly change post- versus pre-intervention (24.1% vs. 23.2%; 95% CI: -1.9 to 3.8; p = .71) but significantly decreased at the satellite ED (7.6% vs. 14.8%; 95% CI: -12.2 to -2.2; p = .01). CONCLUSIONS A universally offered screening intervention increased the proportion of adolescents who were tested at both EDs and the detection rates for CT/GC at the main ED, but patient acceptance of screening was low.

Abstract
OBJECTIVE The incidence and death rate of lung cancer has been rising year by year. Non-small cell lung cancer (NSCLC) seriously affects people's health and quality of life. This study was designed to explore the functional role of long-chain non-coding RNA (LncRNA) MIR503HG in the development of NSCLC. PATIENTS AND METHODS The quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) assay was conducted to access the expression level of MIR503HG in NSCLC cell lines and tissues. The Cell Counting Kit-8 (CCK-8) assay, colony formation assay, and flow cytometric analysis were performed to assess the ability of MIR503HG in regulating cell proliferation and apoptosis in NSCLC. Subsequently, Western blotting was used to detect the expression level of Wnt1 in NSCLC. Besides, in vivo tumorigenesis assay was performed in nude mice to examine the ability of MIR503HG in tumor formation. RESULTS MIR503HG was downregulated in NSCLC. CCK-8 assay and colony formation assay revealed that MIR503HG negatively regulated cell proliferation in NSLCL progression. In addition, MIR503HG promoted cell apoptosis and suppressed cell cycle progression in NSCLC in vitro. MIR503HG inhibited tumor formation in nude mice bearing NSCLC in vivo. MIR503HG downregulated Wnt1 expression in NSCLC. CONCLUSIONS Lon non-coding RNA MIR503HG was downregulated in NSCLC. The over-expression of MIR503HG suppressed cell proliferation and promoted cell apoptosis in vitro and repressed tumorigenesis in vivo. MIR503HG suppressed NSCLC progression via negatively regulating Wnt1 expression.

Abstract
OBJECTIVE The aim of this study was to explore the effect of long non-coding ribonucleic acid (lncRNA) ROR on myocardial fibrosis in rats with viral myocarditis by regulating c-myc expression. MATERIALS AND METHODS A total of 120 healthy male rats were randomly divided into three groups, including: blank control group (group N, healthy rats, n=40), model control group (group M, viral myocarditis, n=40), and group P (lncRNA ROR + viral myocarditis, n=40). At 5, 10, and 15 d after modeling, the rats were sacrificed. Meanwhile, the left ventricular mass index (LVMI), the left ventricular weight/tibial length (LVW/TL) and the heart mass index (HMI) were measured, respectively. The myocardial tissues of rats were observed via staining. The protein and mRNA expressions of the transforming growth factor-β (TGF-β) and c-myc in myocardial tissues were detected via Western blotting and quantitative Real Time-Polymerase Chain Reaction (qRT-PCR), respectively. Moreover, the level of the serum interleukin-6 (IL-6) was detected via enzyme-linked immunosorbent assay (ELISA). RESULTS Compared with group N, HMI, LVMI, and LVW/TL in group M significantly increased at each time point (p<0.01). Meanwhile, they were remarkably elevated at each time point in group P when compared with those in group M (p<0.01). According to the results of hematoxylin-eosin staining (HE) staining, the myocardial fibers were normal and orderly arranged in group N. Meanwhile, no inflammatory cells were observed in group N. In group M, the proliferation of a large number of inflammatory cells was observed, and the myocardial cells were disorderly arranged and became enlarged. In group P, the myocardial fibrosis was significantly severer than that of the other two groups (p<0.05). The results of the Masson staining revealed that there was significantly less accumulation of collagen fibers in myocardium in group N. There was a little accumulation of collagen fibers in the myocardium and fibrosis declined in group M. The myocardial fibrosis in group P remarkably increased when compared with group M (p<0.05). According to the results of the Western blotting, the protein expressions of c-myc and TGF-β were significantly up-regulated in group P, compared with those in group M and N (p<0.05). However, they were remarkably higher in group M than in group N (p<0.05). QRT-PCR showed that the relative messenger ribonucleic acid (mRNA) expressions of c-myc and TGF-β were remarkably up-regulated in group P when compared with those in group M and N, showing statistically significant differences (p<0.05). Moreover, they were significantly higher in group M than those in group N (p<0.05). Besides, the expression level of serum IL-6 remained highest in group P (p<0.01). CONCLUSIONS LncRNA ROR up-regulates the expression of c-myc and increases the level of serum IL-6, thereby facilitating the proliferation and differentiation of cardiac fibroblasts.

Abstract
Abstract
Background
Prediction of death is the philosopher's stone of arrhythmology. The electrophysiology has proven to be an important tool to predict the risk of death. Periodic repolarization dynamics (PRD) is a novel electrocardiographic marker that indicates the sympathetic effect on repolarization. PRD qualifies the low-frequency oscillations of cardiac repolarization instability using high-resolution 12 channel 24-h Holter recording. Several studies showed that PRD was an independent predictor of all-cause mortality and cardiac mortality. However, the prediction value of PRD has not been established.
Purpose
To evaluate the prediction value of PRD as an approach of risk stratification that selects patients at a higher risk of death.
Methods
We conducted electronic searches of MEDLINE (PubMed), Embase, Cochrane Register of Controlled Trials (CENTRAL), Science Citation Index Expanded, WHO International Clinical Trials Registry platform (ICTRP) and ClinicalTrials.gov from inception to January 9th, 2020. We also screened for relevant abstracts from conferences including ACC Annual Scientific Sessions, ESC Congress and Annual Congress of the EHRA for the last five years (2014–2019). The primary outcome was all-cause mortality and secondary outcome was cardiac mortality. We included study with large sample size while more than one study were found based on the same originated population. We extracted data from included studies and reported pooled outcomes as hazard ratios (HRs) with 95% confidential intervals (CI) for time-to-event outcomes using DerSimonian-Laird random-effects model. We did statistical analyses using Stata version 12.0 and R version 3.6.1.
Results
5 studies including 6758 patients met all selection criteria for our meta-analysis. Follow-up period ranged from 20.4 to 75.1 months. Among 5 studies, 3 studies considered PRD as dichotomous variable and the cut-off value was 5.75 deg2, while 2 studies considered PRD as continuous variable and coefficient was expressed in standardized units (increase per standard deviation). We did subgroup analysis according to the type of variable because of heterogeneity. There was a significant higher risk of all-cause mortality in PRD ≥5.75 deg2 patients compared with PRD <5.75 deg2 patients (HR 2.37, 95% CI 1.77–3.17). As for continuous variable, increased PRD was a predictor for all-cause death (HR 1.28, 95% CI 1.14–1.42) (Figure). The cardiac mortality was significantly increased in patients with PRD ≥5.75 deg2 vs PRD <5.75 deg2 (HR 3.06, 95% CI 1.66–5.65). Increased PRD was associated with cardiac mortality in continuous variable subgroup (HR 1.34, 95% CI 1.21–1.48) (Figure).
Conclusion
Our findings suggest PRD is a significant predictor of all-cause mortality and cardiac mortality. PRD provides new additional electrophysiological indicator for risk stratification until further investigations are available.

Abstract
Abstract
Background
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart muscle disease characterized by fibrofatty replacement of the myocardium and ventricular arrhythmias. Biventricular (BiV) involvement in ARVC may lead to heart failure.
Purpose
This study aimed to investigate the role of novel plasma biomarkers soluble (s)ST2, Galectin-3 (Gal-3) and GDF-15 in predicting BiV involvement and adverse outcomes in ARVC patients.
Methods
ARVC patients from two independent cohorts were studied. 108 patients were included from the discovery cohort and 47 patients were included from a second validation cohort. All patients had a definite ARVC diagnosis at time of blood withdrawal. sST2, Gal-3 and GDF-15 were independently correlated with NT-proBNP, left ventricular (LV) ejection fraction, late gadolinium enhancement by cardiac magnetic resonance (CMR) imaging and clinical outcome.
Results
ARVC patients with LV involvement had higher levels of sST2 and GDF-15 as compared to controls and patients with isolated right ventricular involvement. sST2 and GDF-15 significantly correlated to late gadolinium enhancement on CMR and also correlated to adverse heart failure outcomes. Gal-3 was elevated in ARVC patients with and without LV involvement as compared to controls. The combined use of the three biomarkers (NT-proBNP, sST2 and GDF-15) showed the best performance in predicting LV involvement in both the discovery and the validation cohort. Plasma drawn from coronary arteries and coronary sinus showed a transmyocardial elevation of sST2.
Conclusion
Our study shows that sST2 and GDF-15 may predict BiV involvement and the combined use of NT-proBNP, sST2 and GDF-15 shows the best prediction of LV involvement in ARVC. Transmyocardial elevation of sST2 suggests that this biomarker is produced by myocardial tissue in ARVC.

Abstract
OBJECTIVE The aim of this study was to explore the correlations of changes in inflammatory factors, glucose and lipid metabolism indicators and adiponectin with alterations in intestinal flora in rats with coronary heart disease. MATERIALS AND METHODS A total of 30 male specific pathogen-free rats were randomly assigned into two groups, including: blank group (n=15) and coronary heart disease group (n=15). The rats in the coronary heart disease group were given high-fat diets and pituitrin to establish the model of coronary heart disease. Meanwhile, rats in the blank group were administered with an equal volume of double-distilled water. The alterations in the intestinal flora of rats were detected in the two groups, respectively. In addition, the changes in the levels of inflammatory factors, glucose and lipid metabolism indicators, adiponectin, creatine kinase (CK) and its isoenzyme, as well as troponin, were also examined. RESULTS Statistically, significant differences in the levels of glucose and lipid metabolism indicators low-density lipoprotein (LDL) (p=0.040), total cholesterol (TC) (p=0.039), high-density lipoprotein (HDL) (p=0.044), triglyceride (TG) (p=0.000) and blood glucose (p=0.046) were observed between the rats in the coronary heart disease group and blank group. The content of all the glucose and lipid metabolism indicators (except HDL) in coronary heart disease group was significantly higher than the blank group (p<0.05). The rats in the coronary heart disease group had evidently higher levels of CK (p=0.000) and its isoenzyme (p=0.019), as well as troponin (p=0.021), than those in the blank group. The level of serum adiponectin in rats in coronary heart disease group was distinctly lower than that in the blank group, showing statistically significant differences (p<0.05). Besides, the levels of the inflammatory factors interleukin (IL)-2 (p=0.011), transforming growth factor (TGF)-β (p=0.048), tumor necrosis factor-α (TNF-α) (p=0.025) and IL-6 (p=0.038) in rats in the coronary heart disease group were dramatically higher than those in blank group. Rats in coronary heart disease group had remarkably more Actinobacteria, Desulfovibrio, Aristipus and Escherichia coli in the intestine. Meanwhile, the abundance of Flavobacterium, Burkhofer and some probiotics increased significantly in the intestine of rats in blank group (p<0.05). The changes in the abundance of Actinobacteria, Desulfovibrio, Aristipus and Escherichia coli in the intestine of rats were probably correlated with increased levels of glucose and lipid metabolism indicators, inflammatory factors and adiponectin in coronary heart disease group. Moreover, the abundance of intestinal probiotics such as Bifidobacterium and Lactobacillus in rats in coronary heart disease group was notably lower than that in blank group (p<0.05). The decline in the abundance of such intestinal probiotics as Bifidobacterium and Lactobacillus was correlated with the changes in the levels of glucose and lipid metabolism indicators, inflammatory factors and adiponectin. In addition, decreased levels of probiotics weakened normal physiological functions of the intestine and promoted disease progression. CONCLUSIONS Inflammatory factors, glucose and lipid metabolism indicators and adiponectin have evident changes in rats with coronary heart disease, which may be correlated with the alterations in the intestinal flora.

Abstract
Tibial dyschondroplasia (TD) is an intractable avian cartilage disease in which proximal growth plates of tibia lack blood vessels and contain nonviable cells, and it leads to the inflammatory response. Prostaglandins (PGs) genes have not been studied yet in TD chicken, and they might play role in skeletal metabolism, therefore we planned to explore the role of recombinant glutathione-S-transferase A3 (rGSTA3) protein and PG-related genes. In this study, qRT-PCR, enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC) analysis were used to identify the expression patterns of eight PG-related genes in the tibial growth plate of broiler chicken. The results showed that the expression of PG-related genes glutathione-S-transferase A3 (GSTA3), cyclooxygenase 2 (COX-2), prostaglandin D2 synthase (PTGDS), prostaglandin E synthase (PTGES), prostaglandin E2 receptor (PTGER) 3, PTGER4, prostaglandin reductase 1 (PTGR1) and hematopoietic prostaglandin D synthases (HPGDS) expression were identified and could significantly respond to thiram-induced TD chicken. Interestingly, the expression of rate-limiting enzyme COX-2 and PGE2 were induced after the treatment of rGSTA3 protein. These findings demonstrated that the occurrence of TD is closely related to the inhibition of PGs. Moreover, rGSTA3 protein participated in the recovery of TD by strengthening the expression of PG-related genes.

Abstract
This study examined the feasibility and acceptability of an evidence-based HIV prevention programme for men who have sex with men (MSM) in Ghana through a participatory approach. The programme involved 57 self-identified adult cisgender MSM and led by a community-based organisation in collaboration with local nurses. We used an explanatory mixed-method design to evaluate the programme. We computed descriptive statistics, relative frequency, and paired proportionate analysis for the survey data and subjected the focus groups data to summative content analysis. Five key themes from the qualitative data indicated strong evidence of the acceptability and efficacy of the programme among MSM. The programme contributed to building social support networks, a sense of social justice among MSM, and facilitated the development of personalised HIV prevention menus by the participants. We observed increases in HIV testing (from 4% to 17%) and increases in the relative frequency of condom use for anal, oral, and vaginal sex. The programme served as an example of a successfully implemented culturally grounded intervention that has the potential to increase HIV and STI awareness and prevention among MSM in Ghana and other highly stigmatised environments.

Abstract
OBJECTIVE Neuroblastoma is a common malignancy in children. Despite the occurrence of diverse therapies in recent years, the survival rate of patients with high-risk NB is still unpredictable due to the high metastatic potential and poor prognosis. Therefore, it is urgent to study the molecular mechanism of NB metastasis. SNHG1 has been reported to be closely related to the development, metastasis, and prognosis of many cancers. The purpose of this study was to clarify the molecular mechanism of the role of SNHG1 in NB tumors. PATIENTS AND METHODS The expression levels of SNHG1, miR-338-3p, and PLK4 were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blot, respectively. The functional targets between miR-338-3p and SNHG1 or PLK4 were predicted by online software Diana tools and observed by Luciferase reporter assay and RIP assay. Cell proliferation was measured by MTT assay. Cell migration and invasion were operated through flow cytometry. The expression of p-AKT was quantified by Western blot. Xenograft tumor model was established to confirm the biological role of SNHG1 in NB in vivo. RESULTS The expression levels of SNHG1 and PLK4 were increased in NB tissues and cells, and miR-338-3p expression was on the contrary. PLK4 was verified as a direct target of miR-338-3p and miR-338-3p could specially bind to SNHG1. The negative effect of SNHG1 down-regulation on cell proliferation, migration, and invasion could be rescued by miR-338-3p inhibition. The suppression of miR-338-3p mimics on cell proliferation, migration, and invasion could be reversed by PLK4 overexpression. In addition, SNHG1 knockdown weakened the volume and weight of tumor in vivo. CONCLUSIONS SNHG1 conduced to tumorigenesis and mechanism by upregulating PLK4 and by acting as miR-338-3p sponge in neuroblastoma.

Abstract
OBJECTIVE The X-linked inhibitor of apoptosis protein (XIAP) is associated with the development of various tumors. The abnormal miR-142 expression is associated with the onset of lung cancer. Bioinformatics analysis revealed a targeted relationship between miR-142 and XIAP. This report investigated whether miR-142 plays a role in regulating XIAP expression and affecting the biological processes of lung cancer cells. PATIENTS AND METHODS The tumor tissues of lung cancer patients were collected, and the adjacent tissues were used as controls. The dual luciferase reporter gene assay validated the targeted regulation between miR-142 and XIAP. Using BEAS-2B cells as control, qRT-PCR was used to detect the expression of miR-142 and XIAP in lung cancer cells A549 and H1650. Lung cancer H1650 cells were cultured and divided into miR-NC group and miR-142 mimic group followed by an analysis of cell proliferation by EdU staining. RESULTS Compared with those in adjacent tissues, miR-142 expression was significantly decreased and XIAP expression was increased in lung cancer tissues. The Dual-Luciferase Reporter Assay confirmed a targeted regulation relationship between miR-142 and XIAP. Compared with BEAS-2B cells, miR-142 expression in lung cancer A549 and H1650 cells was significantly decreased, and XIAP expression was significantly increased. Transfection of miR-142 mimic significantly inhibited the expression of XIAP in H1650 cells, promoted apoptosis and inhibited cell proliferation. CONCLUSIONS Decreased miR-142 expression and increased XIAP expression is associated with the onset of lung cancer. MiR-142 can inhibit lung cancer cell proliferation and induce apoptosis through inhibition of XIAP expression.

Abstract
Objective: To analyze the association of two single-nucleotide polymorphisms (SNP) [Calcitonin gene related peptide (CGRP) rs155209 and receptor activity modifying protein 1 (RAMP1) rs3754701] and the prognosis of chronic hepatitis B patients who were under interferon therapy. Methods: A total of 317 patients and their anticoagulant blood samples were collected in this study. The SNPs in the CGRP and region RAMP1 were genotyped using matrix-assisted laser desorption/ionization time of flight mass spectrometry. Logistic regression method was used to assess the results from different phenotypic outcomes between cases and controls, after adjusted for sex and age in co-dominant, dominant and recessive genetic models. Results: Data from this study clearly demonstrated the relevance of CGRP rs155209 and RAMP1 rs3754701 with DNA response and ALT response. RAMP1 rs3754701T was strongly associated with both DNA response and ALT response (OR=2.277, 95%CI: 1.386-3.741, P=0.001; OR=1.694, 95%CI: 1.073-2.675, P=0.024). However, CGRP rs155209C was less prone to DNA response and ALT response (OR=0.150, 95%CI: 0.083-0.271, P<0.001; OR=0.583, 95%CI: 0.367-0.925, P=0.022). Conclusions: Results from our study suggested that both RAMP1 rs3754701 and CGRP rs155209 were associated with the prognosis of patients under interferon therapy in Han population, from the northern parts of China while RAMP1 rs3754701T was a protective factor for both ALT response and DNA response, but CGRP rs155209C carriers were less prone to DNA and ALT responses.

Abstract
OBJECTIVE The specific mechanism of cytokine storm in COVID-19 infected patients is not clear. This study aims to identify the key genes that cause cytokine storm in COVID-19 infected patients. MATERIALS AND METHODS We conducted a difference analysis on the GSE147507 data set. The analysis results are combined with immune genes to obtain immune-related genes among the differential genes. Finally, GO enrichment analysis, PPI analysis, core gene identification, and ssGSEA enrichment analysis were performed on the new gene set. RESULTS A total of 232 differential genes were screened out. After merging with immune genes, a total of 29 immune-related genes were obtained. Further analysis revealed that the genes were enriched in 16 pathways, and the protein interaction network had a total of 29 nodes and 139 edges. After screening, the core gene was CXCL10. The ssGSEA results of CXCL10 showed that CD4 and CD8 immune-related signature were significantly enriched in high CXCL10 expression, and the samples with low CXCL10 expression were significantly enriched with monocytes and DC immune-related signature. CONCLUSIONS CXCL10 may be a key gene related to the cytokine storm of COVID-19 infection, and it is expected to become the therapeutic target.

Abstract
Purpose: To examine the long-term consequences of early childhood traumatic brain injury (TBI), approximately 6.8 years post-injury, on cognitive communication competency within a complex interplay of individual, contextual, and psychosocial factors. Additionally, we were interested in looking at the association of communication competence with social competence and overall functioning.Methods: 64 children with orthopedic injury, 40 children with moderate traumatic brain injury, and 14 children with severe traumatic brain injury who were between 3 years and 6 years 11 months at injury completed a narrative discourse task and clinical measures in a single visit at a longer term follow up in early adolescence, an average of 6.8 years post injury. Analyses of covariance were conducted to compare groups on the discourse task, and hierarchical linear regressions were conducted to examine the association of discourse measures with clinical measures of cognitive and psychosocial functioning.Results: Children with severe traumatic brain injury performed worse than children with moderate traumatic brain injury and orthopedic injury on all discourse indices and clinical measures. Injury severity, pragmatic skills, and socioeconomic status were associated with discourse gist. Discourse gist was the most sensitive measure of communication competence, and it was significantly associated with psychosocial outcomes independent of group.Conclusion: Children who sustain a severe traumatic brain injury in early childhood are at risk for long-term cognitive communication impairments that may be related to a complex interplay of injury, individual, and social factors.Implications for rehabilitationThe assessment and treatment of cognitive communication impairments after traumatic brain injury are complex and require consideration of individual, contextual, and psychosocial factors.Discourse, in general, and gist reasoning specifically, is a sensitive measure for detecting cognitive communication competence several years after pediatric traumatic brain injury.Treatments to address gist reasoning deficits may support improvements in global and social functioning.

Abstract
Objective: To explore the differential protein expressions in papillary thyroid carcinoma (PTC) with or without Hashimoto's thyroiditis (HT). Methods: Tissue microarray was prepared and the protein expression levels of v-Raf murine sarcoma viral oncogene homolog B1 (BRAF), vascular endothelial growth factor (VEGF), cyclinD1, mesothelial cell (MC) , CD56 and Galectin3 in the PTC tissues with or without HT were detected by immunohistochemical staining. Results: The positive expression rates of BRAF protein in the PTC tissues with or without HT groups were 55.4% (36/65) and 63.6% (42/66), respectively, without significant difference (P=0.336). The positive expression rates of VEGF protein in the PTC tissues with or without HT groups were 25.7% (19/74) and 25.8%(17/66), respectively, without significant difference (P=0.991). The positive expression rates of cyclin D1 protein in the PTC tissues with or without HT groups were 93.4% (71/76) and 97.6% (80/82), without significant difference (P=0.206). The positive expression rates of MC protein in the PTC tissues with or without HT groups were 86.1% (62/72) and 83.5%(71/85), without significant difference (P=0.654). The positive expression rates of Galectin3 protein in the PTC tissues with or without HT groups were 98.7% (76/77) and 97.5% (78/80), without significant difference (P=0.583). The positive expression rates of CD56 in the PTC tissues and adjacent thyroid follicular epithelial cells were 27.4% (32/117) and 65.0% (76/117), respectively, and the difference was statistically significant (P=0.001). The positive expression rates of CD56 in PTC tissues with or without HT were 35.5% (24/68) and 16.5% (13/79), respectively, and the difference was statistically significant (P=0.009). Conclusions: There are no significant differences in the expressions of BRAF, VEGF, CyclinD1, MC and Galectin3 between the PTC tissues with or without HT. However, the significantly differential expression of CD56 between the two group suggests that CD56 may be related to the pathogenesis of PTC with HT. CD56 may be used as a potential molecular marker in PTC diagnosis.

Abstract
Objective: To investigate the prognostic factors of patients with low-frequency type of sudden sensorineural hearing loss. Methods: From February 2017 to February 2019, adult patients with unilateral low-frequency type of sudden sensorineural hearing loss in Department of Otological Medicine, Shandong Provincial ENT Hospital, Shandong University were selected. All patients were examined by audiology, vestibular function evaluation, imaging examination and serum thyroid function test; the same treatment program was given, the curative effect was recorded and followed up for more than 3 months. SPSS 20.0 software was used to analyze concomitant symptoms (tinnitus, ear tightness, echo, rotatory vertigo), degree of deafness, inducement of deafness, basic disease, vestibular function (caloric test), electrocochleogram, inner ear gadolinium enhanced MRI radiography and thyroid function on prognosis of patients. Results: Among the 155 patients, 76 cases were cured (49.0%), 1 case was markedly effective (0.6%), 19 cases were effective (12.3%), and 59 cases were ineffective (38.1%). The total effective rate was 61.9%. Among them, 24 cases (15.5%) had hearing fluctuations during follow-up, and 1 case (0.6%) developed Meniere's disease. Univariate analysis showed that vestibular function, electrocochleogram and inner ear MRI were correlated with prognosis. Multivariate logistic analysis showed that ear tightness, vestibular function, electrocochleogram and inner ear MRI were correlated with the prognosis of the patients. The two analyses showed that tinnitus, echo, rotational vertigo, degree of deafness, predisposing factors and underlying diseases were not significantly correlated with the prognosis of the patients (all P>0.05). Rotational vertigo was closely related to gender, and women had a high incidence. There was a significant correlation between the degree of deafness and prognosis in patients with course of less than 1 week (P<0.05). The abnormal rate of vestibular function in patients with course of disease ≤ 1 week was significantly different from that>1-≤2 and>2-≤4 weeks (P<0.05). The rate of abnormal thyroid function was significantly higher than that of normal people (P<0.05), but there was no significant correlation between thyroid dysfunction and hearing prognosis (χ(2)=0.009, P=0.923) . Conclusions: The prognosis of low-frequency sudden sensorineural hearing loss is not related to clinical symptoms, inducements, underlying diseases and serological abnormalities of thyroid function, but the degree of deafness is positively related to the prognosis within 1 week from onset. Abnormal thyroid function is one of the risk factors of happening with low-frequency descending sudden deafness. Abnormal vestibular caloric test, electrocochleogram and endolymph hydrops are the factors of poor prognosis.

Abstract
This study aimed to investigate the effect of resveratrol on methane production, rumen fermentation and microbial composition under high-concentrate (HC) and high-forage (HF) diets using the in vitro fermentation system. A total of 25 mg of resveratrol was supplemented into 300 mg of either HC or HF diet. Methane production, total volatile fatty acid (VFA) concentration, molar proportion of VFA, metabolites of resveratrol and prokaryotic community composition were measured after 12 and 24 h of in vitro fermentation. Resveratrol reduced methane production (ml per mg of dry matter degraded) by 41% and 60% under both HC and HF diets (P < 0.001), respectively, and this result could be associated with the lower abundance of Methanobrevibacter (P < 0.001) in response to resveratrol. The molar proportion of propionate was significantly higher in the resveratrol group only under the HC diet (P = 0.045). The relative abundance of 10 bacterial genera was affected by the three-way interaction of treatment, diet and time (P < 0.05). Resveratrol was partly converted to dihydroresveratrol after 24 h of fermentation, and its degradation could be associated with microbes belonging to the order Coriobacteriales. Our results suggest that multiple factors (e.g. diet and time) should be considered in animal experiments to test the effect of polyphenol or other plant extracts on rumen fermentation, methane emission and microbial composition.

Abstract
PURPOSE Multiple primary colorectal cancers (MPCCs) are different from solitary colorectal cancers in many aspects, which are not well studied. The aim of this study was to clarify the clinicopathological features and prognosis of MPCCs. METHODS The data of 64 patients with MPCCs out of 2300 patients with colorectal cancers (CRCs) from January 2009 to December 2017 were retrospectively analyzed. Stratified analysis was conducted based on subtypes and microsatellite status. RESULTS The overall incidence of MPCC was 2.8% and the median follow-up duration was 51.5 (range 1-120) months. Metachronous CRCs (MCRCs) are more likely to appear in the right colon (p < 0.05). However, no significant differences regarding age, sex, BMI, tumor size, smoking/drinking history, TNM stage, family history of cancer, and 5-year survival rate were observed between synchronous CRC (SCRC) and MCRC. Advanced TNM stage (III) and the presence of polyps were found to be independent poor prognostic factors for MPCCs. The prevalence of mismatch repair deficiency (dMMR) in MPCCs was 28.1%. Deficient MMR is more likely to appear in younger, lighter MPCC patients with polyps (p < 0.05). Of four mismatch repair proteins, MLH-1, MSH-2, MSH-6, and PMS-2 were negative in nine, nine, five, and nine patients, respectively. The 5-year survival rate did not differ significantly between MMR-proficient (pMMR) and dMMR groups (p = 0.752). CONCLUSIONS Synchronous CRC (SCRC) and MCRC might represent similar disease entities with different courses. Deficient MMR is more likely to appear in younger, lighter MPCC patients with polyps and it is an essential indicator for screening Lynch syndrome.

Abstract
INTRODUCTION The transplant waiting list exceeds the number of organs available. One means of increasing the organ pool is to broaden potential donors to include those with chronic diseases. RESEARCH QUESTIONS The study tested the effectiveness of using peer mentors to encourage individuals on dialysis to enroll on an organ donor registry. DESIGN Dialysis units were pair-matched by size and racial composition and then randomized to one of 2 interventions: meetings with a peer mentor (experimental intervention) or organ donation mailings (control). Peer mentors were trained to discuss organ donation with individuals on dialysis during in-person meetings at dialysis units. The primary outcome was verified registration in the state's donor registry. RESULTS After adjusting for age, gender, race, income, and education and accounting for correlation within the dialysis center, there was a significant intervention effect. Among individuals in the intervention group, the odds of enrolling (verified) on the donor registry were 2.52 times higher than those in the control group. DISCUSSION The use of peer mentors to discuss donating organs after death with individuals on dialysis can increase enrollment on a donor registry. Dispelling myths about chronic illness and donation can counter widely held misconceptions and help persons make an informed choice about end-of-life decisions and present an opportunity to increase the number of organs and tissues available for transplant.

Abstract
BACKGROUND Frontal fibrosing alopecia (FFA) is a scarring alopecia with unclear pathogenesis and a progressive course. The disease has a major impact on patients' quality of life and there is a lack of effective treatment to halt disease progression. METHODS We profiled lesional and nonlesional scalp biopsies collected in 2017 from patients with FFA (n = 12) compared with scalp biopsies from patients with alopecia areata (AA) (n = 8) and controls (n = 8) to evaluate gene and protein expression, including the primary outcome (CXCL9). We determined significant differences between biomarkers using a two-sided Student's t-test adjusting P-values by false discovery rate. RESULTS Significant increases were seen in CD8+ cytotoxic T cells, CD11c+ dendritic cells, CD103+ and CD69+ tissue-resident memory T cells in FFA and AA vs. control scalp (P < 0·05), with corresponding significantly upregulated granzyme B mRNA, particularly in FFA (P < 0·01). In AA, cellular infiltrates were primarily concentrated at the bulb, while in FFA these were mainly localized at the bulge. FFA demonstrated significant upregulation of T helper 1/intereferon (IFN) (IFN-γ, CXCL9/CXCL10), the Janus kinase/signal transducers and activators of transcription (JAK-STAT) pathway (STAT1, JAK3) and fibrosis-related products (vimentin, fibronectin; P < 0·05), with no concomitant downregulation of hair keratins and the T-regulatory marker, forkhead box P3, which were decreased in AA. The stem cell markers CD200 and K15 demonstrated significantly reduced expression only in FFA (P < 0·05). CONCLUSIONS These data suggest that follicular damage and loss of stem cells in FFA may be mediated through immune attack in the bulge region, with secondary fibrosis and reduced but still detectable stem cells. JAK/STAT-targeting treatments may be able to prevent permanent follicular destruction and fibrosis in early disease stages.

Abstract
Background:Pulmonary arterial hypertension (PAH) is a fatal complication of connective tissue diseases (CTDs). Chest CT has been increasingly used in the evaluation of patients with suspected PH noninvasively but there is a paucity of studies.Objectives:Our study was aimed to investigate the cross-sectional area (CSA) of small pulmonary vessels on chest CT for the diagnosis and prognosis of CTD-PAH.Methods:This retrospective study analyzed the data of thirty-four patients with CTD-PAH who were diagnosed by right heart catheterization (RHC) and underwent chest CT between March 2011 and October 2019. We measured the percentage of total CSA of vessels<5 mm2and 5-10 mm2as a percentage of total lung area (%CSA<5and %CSA5-10) on Chest CT. Furthermore, the association of %CSA with mean pulmonary artery pressure (mPAP) was also investigated. Besides, these patients were followed up until October 2019, and Kaplan-Meier survival curves were generated for the evaluation of prognosis.Results:Patients with CTD-PAH had significantly higher %CSA5-10than CTD-nPAH (p=0.001), %CSA5-10in CTD-S-PAH and IPAH was significantly higher than CTD-LM-PAH and COPD-PH (p<0.01). There was a positive correlation between %CSA5-10and mPAP in CTD-PAH (r=0.447, p=0.008). Considering %CSA5-10above 0.38 as a threshold level, the sensitivity and specificity were found to be 0.824 and 0.706, respectively. Patients with %CSA5-10≥0.38 had a lower survival rate than those with %CSA5-10<0.38 (p=0.049).Conclusion:Quantitative parameter, %CSA5-10on Chest CT might serve a crucial differential diagnostic tool for different types of PH. %CSA5-10≥0.38 is a prognostic indicator for evaluation of CTD-PAH.References:[1]Galie N, Humbert M, Vachiery JL, et al. 2015 ESC/ERS Guidelines for the Diagnosis and Treatment of Pulmonary Hypertension.

Abstract
Organ temperature and variation therein plays a key role in plant functioning and its responses to e.g. climate change. There is a strong feedback between organ, especially leaf, temperature and the climate within the canopy (canopy climate), which in turn interacts with the climate outside the canopy (ambient climate). For greenhouses, the determinants of this interplay and how they drive differences between canopy and ambient climate are poorly understood. Yet, as many experiments on both regular greenhouse crops and field crops are done in greenhouses, this is crucial to know. Therefore, we designed an experiment to quantify the differences between ambient and canopy climate and leaf temperature. A path analysis was performed to quantify the interactions between components of the greenhouse canopy-climate system. We found that with high radiation the canopy climate can be up to 5°C cooler than the ambient climate, while for cloudy days this was only 2°C. Canopy relative humidity (RH) was up to 25% higher compared to ambient RH. We showed that radiation is very important for these climate differences, but that this effect could be partly counteracted by turning off supplementary light (i.e. due to its indirect effects e.g. changing light distribution). Leaf temperature was substantially different, both higher and lower, from the canopy air temperature. This difference was determined by leaf area index (LAI), temperature of the heating pipe and the use of supplementary light, which all strongly influence radiation, either shortwave or thermal radiation. The difference between leaf and ambient air temperature could be decreased by decreasing the LAI or increasing the temperature of the heating pipe.

Abstract
Abstract
Introduction
The Department of Veterans Affairs has pioneered the use of home sleep apnea testing (HSAT) across many of its medical centers over the past 15 years. Here we report trends regarding diagnostic sleep apnea testing in rural and urban Veterans served by the TeleSleep Program, a VA telehealth initiative focused on increasing access to sleep care for rural Veterans. Rurality is a risk factor for use of polysomnography and is associated with longer wait times for testing and initiation of PAP therapy.
Methods
We used a VA administrative database search of patients enrolled in sleep medicine clinics from fiscal years (FY) 2016-2019 at 7 TeleSleep Hubs: San Francisco, Portland, Phoenix, Boise, Philadelphia, Spokane, and Pittsburgh. Individual encounters were coded locally and transmitted to VA’s corporate data warehouse. HSAT codes included 95800, 95801, 95806, G0398, G0399, and G0400. Polysomnography codes included 95807, 95808, 95810, and 95811.
Results
Total number of unique Veterans served increased between FY16 and FY19 from 28,941 to 43,044 (149%); rural Veterans served during this time increased from 9,386 to 14,329 (153%). The total number of annual sleep medicine encounters for all Veterans served increased from 89,870 to 138,127 (154%); rural Veteran visits increased from 29,825 to 50,342 (169%). Unique urban Veterans tested by HSAT increased from 2,158 in FY16 to 4,398 in FY19 (203%) while polysomnography decreased from 5,011 to 3,253 (35%). Unique rural Veterans tested by HSAT increased from 1,102 to 2,768 (251%) and polysomnography decreased by 42% (1,565 to 909 Veterans) during this same time.
Conclusion
Among VA sleep medicine programs with TeleSleep funding, HSAT became the most common approach to diagnostic sleep apnea testing, particularly in rural Veterans. Although polysomnography was widely used at the beginning of the TeleSleep Initiative, use declined as HSAT became more widely implemented.

Abstract
Short sleep has been linked to adolescent risk of obesity, but questions remain regarding the dietary mechanisms by which this occurs. We tested whether mildly shortening sleep influences how rewarding and appealing healthy adolescents find several kinds of foods. Eighty-eight healthy adolescents completed a within-subjects crossover sleep experiment comparing 5 days of Short Sleep (6.5 hr sleep opportunity) with 5 days of Healthy Sleep (9.5 hr sleep opportunity). Following each condition, adolescents completed measures of food appeal and reinforcing value of food across five food types: sweets/desserts, fruits/vegetables, lean meats/eggs, fast food and processed snacks. Adolescents averaged 2.2 hr/night longer sleep periods in Healthy Sleep versus Short Sleep. We observed a significant interaction of experimental order with sleep condition on three of four primary outcomes related to the appeal and reinforcing value of foods (p's < .005). When Short Sleep preceded Healthy Sleep, adolescents endorsed significantly greater appeal (p < .04) and rewarding value of food (p's ranging from <.01 to .048) during Short Sleep (compared to Healthy Sleep). However, when Healthy Sleep preceded Short Sleep, we did not observe a main effect of sleep condition on the same outcomes (p's > .05). This study provides evidence that restricting adolescents' sleep opportunity to 6.5 hr (compared to sleeping a healthy amount) increases the appeal and reinforcing value of a variety of foods, but this may occur only under protracted short sleep. Increased food reward may be one mechanism linking chronically shortened sleep with risk of obesity in adolescence.

Abstract
Ion displacements are the fundamental cause of ferroelectricity in perovskites. By properly shifting ions,ab initiocomputations have been extensively used to investigate the properties of perovskites in various structural phases. In addition to the relatively simple ion displacements, perovskites have another type of structural distortion known as antiferrodistortion or oxygen octahedron tilting. The interplay between these two types of distortions have generated abundant structural phases that can be tedious to prepare forab initiocomputation, especially for large supercells. Here, we design and implement a computer program to facilitate the generation of distorted perovskite structures, which can be readily used forab initiocomputation to gain further insight into the perovskite of a given structural phase.

Abstract
Objective: To set up a prediction scoring system for the hypoxemia in infants with Pierre Robin sequence after weaning and evaluate its clinical value. Methods: Data of consecutive patients from November 2016 to June 2019, who underwent mandibular distraction osteogenesis in Guangzhou Women and Children's Medical Center, were retrospectively analyzed (n=148). All the cases were divided into two groups according to the appearance of hypoxemia after weaning. They were randomly divided into the derivation cohorc (2/3,n=100) and the validation cohort (1/3,n=48). Single factor and multiple logistic regression analysis were used to select the independent risk factors related to hypoxemia and establish a prediction model. A prediction scoring system was developed in accordance with assigning of the value of each variable β in the model. Internal verification of scoring system by validation population. Data of consecutive patients from July 2019 to November 2019, who underwent mandibular distraction osteogenesis, were prospectively analyzed (n=26). The diagnostic accuracy were conducted to evaluate the clinical value of the scoring system. Results: The logistic regression demonstrated that age at operation, pulmonary infection and the length of distraction less than 5 mm at weaning were the independent risk factors for hypoxemia. The P value of logistic regression model in Hosmer and Lemeshow goodness of fit test was 0.848, and a prediction scoring system was established accordingly. The area under the ROC curve of the scoring system was 0.890, and the optimum critical value was 53. The sensitivity, specificity, accuracy of the model were 78.6%(11/14),86.1%(74/86), 85.0%(85/100) respectively. The predictive effectiveness of the scoring system in the retrospective validation population was similar to that in the modeling population. 26 patients were included in the prospective analysis. The area under ROC curve of the scoring system was 0.870. The sensitivity, specificity and accuracy were 80.0%(5/6),95.0%(20/21), 96.1%(25/26) respectively. Conclusion: The prediction scoring system established in the study are efficacious for the hypoxemia in infants with Pierre Robin sequence after weaning.

Abstract
Ichthyosis hystrix, Curth-Macklin type (IHCM) is an extremely rare autosomal dominant dermatosis caused by mutations in the keratin genes, KRT1 or KRT10, which often manifests as extensive, dark, spiky or verrucous plaques and severe palmoplantar keratoderma. We report a novel frameshift truncation mutation, c.1596_1597insAT (p.Gly533Metfs*82) in exon 7 (V2 tail domain) of KRT1, which, by replacing the glycine-serine-rich tail of KRT1 with a series of 75 alanine-rich amino acids, produces a mild IHCM phenotype. The patient with the mutation presented with localized ichthyosis and progressive hyperkeratosis of the palms and soles with no history of blistering.

Abstract
Healthcare disparities exist in pediatric asthma in the United States. Children from minority, low-income families in inner-city areas encounter barriers to healthcare, leading to greater rates of poorly controlled asthma and healthcare utilization. Finding an effective way to deliver high-quality healthcare to this underserved population to improve outcomes, reduce morbidity and mortality, and reduce healthcare utilization is of the utmost importance. The purpose of this study was to assess the feasibility and efficacy of a novel school-based care delivery model that incorporates video-based telehealth (VBT) medical and self-management visits with electronic inhaler monitoring to improve asthma outcomes. Over a 6-month period, children from inner-city, low-income schools with uncontrolled asthma completed seven scheduled medical visits with an asthma specialist and five self-management visits with an adherence psychologist at school using VBT. Composite Asthma Severity Index (CASI) scores and electronic inhaler monitor data were recorded and analyzed. A total of 21 patients were enrolled in the study. Study subjects with higher baseline severity (CASI ≥ 4 at visit 1) demonstrated a greater reduction in their score than those with lower baseline severity (CASI < 4 at visit 1). The CASI domains showed improvement in daytime symptoms, nighttime symptoms, and exacerbations. Adherence results demonstrated a significant improvement in adherence from baseline to postintervention. Study retention was 100%. This study demonstrates that a multicomponent medical and behavioral interventional program delivered by VBT to a school-based setting is feasible and can significantly improve asthma outcomes and care in a challenging population.

Abstract
The regulatory function of histone acetylation in the expression of genes encoding heat shock proteins (Hsps) has been documented in Drosophila melanogaster; however, knowledge of the role of acetylation in modulating Hsps in other insect pests is limited. In this study, two full-length cDNAs encoding inducible Hsp70 (designated TcHsp70) and heat shock cognate 70 (TcHsc70) were isolated and characterized in the red flour beetle, Tribolium castaneum. TcHsp70 and TcHsc70 cDNAs were 2256 and 2132 bp and encoded 1941- and 1893-bp open reading frames, respectively. The deduced TcHsp70 and TcHsc70 proteins contained 646 and 630 amino acids, respectively, and contained sequences typical of the Hsp70 family, including the EEVD motif for cytoplasmic localization. Expression patterns after heat shock indicated that TcHsp70 was strongly heat-inducible, whereas the expression level of TcHsc70 remained unchanged under heat shock. RNA interference-mediated knock-down of three genes encoding class I histone deacetylases differentially influenced both basal and heat shock inducible expression of TcHsp70 and TcHsc70, suggesting the involvement of histone acetylation in epigenetic regulation of Hsp70 transcription in T. castaneum.
