Authors: Peng Li , Dai Yi 
Published: December 2019

Objective To explore the effect of metronidazole combined with autolytic debridement for the management of malignant wound malodor. Methods Patients with malignant wounds who underwent dressing change at a wound outpatient clinic from September 2016 to February 2019 were randomized to an observation group (36 patients) or a control group (37 patients). The observation group was treated with metronidazole combined with debridement gel while the control group received wet dressing therapy combined with silver sulfadiazine. Malodor control was compared between the two groups from treatment initiation to days 3 and 12 after dressing change, and the social impact scale was used to compare stigma caused by malodor between the groups before and after treatment. Results The observation group had significantly superior malodor control on days 3 and 12 after dressing change compared with the control group. There was no difference in stigma between the two groups before treatment, but stigma in the observation group was significantly lower than that in the control group after treatment. Conclusion Metronidazole combined with autolytic debridement can effectively reduce the malodor of cancerous wounds while controlling infection, and alleviate patient stigma caused by malodor.

Objective This study compared the impact of gradual oculomotor training (GOT) in blow-out orbital fracture (BOF) reconstruction recovery with the impact of high-intensity trainings. Methods In total, 120 patients with BOF requiring orbital reconstruction surgery were randomly divided into four groups; all groups performed postoperative oculomotor training four times per day. Patients in Groups 1, 2, 3, and 4 performed 10, 20, 30, and 50 sets of all-direction movement per training on the first 3 days, respectively; they performed 10 additional sets per training on the following 4 days. Patients in all groups performed 50 sets per training from 8 days to 3 months postoperatively. Incision healing, pain, and satisfaction rate, as well as degree of diplopia, were recorded during follow-up. Results At 7 days postoperatively, more patients in Group 1 had no/mild swelling and no/mild pain, compared with patients in Group 4. Patients in Groups 1 and 2 had higher satisfaction rates than patients in Group 4. The degree of diplopia did not significantly differ among the groups. Conclusions For patients with BOF, GOT after reconstruction surgery was more beneficial for wound healing, pain relief, and satisfaction; the degree of diplopia did not significantly differ, compared with high-intensity trainings.

Objective Type 2 diabetes mellitus (T2DM) is a main risk factor for development of cardiovascular diseases (CVDs) and endothelial dysfunction. This study aimed to investigate serum levels of soluble vascular cell adhesion molecule 1 (sVCAM-1), intercellular adhesion molecule 1 (sICAM-1), and endothelium selectin (sE-selectin) in T2DM patients with macrovascular complications. Methods A cross-sectional study of 21 controls, 30 T2DM patients without CVDs, and 30 T2DM patients with CVDs was conducted. Serum levels of soluble adhesion molecules including sVCAM-1, sICAM-1, and sE-selectin were determined using ELISA. Results Serum levels of sVCAM-1, sICAM-1, and sE-selectin were higher in T2DM patients than in controls. Levels of serum sVCAM-1 were higher in T2DM patients with CVDs compared with T2DM patients without CVDs. In T2DM patients with CVDs, significant positive associations were observed between sVCAM-1, sICAM-1, and sE-selectin levels (r = 0.575, p = 0.001 and r = 0.378, p = 0.040). Conclusions Circulating levels of soluble adhesion molecules were elevated in T2DM patients, regardless of whether the patients had cardiovascular complications. Only sVCAM-1 was considered a useful marker for the prediction of CVDs in T2DM patients.

Authors: Nie Dan , Yan Xiue , Huang Yonghui 
Published: December 2019

Objective Endoscopic submucosal dissection (ESD) is widely used in early-stage esophageal cancer, but the quality of life of patients with postoperative stricture is markedly reduced, requiring long-term repeat, periodic endoscopic balloon dilatation. We evaluated the combination of hydrocortisone sodium succinate and aluminum phosphate gel administered orally for stricture prevention. Methods We retrospectively assigned 27 patients who underwent ≥3/4 circular ESD for esophageal superficial squamous cell cancer to one of two groups according to the preventative strategy: endoscopic intralesional steroid injection and systemic steroid (IT+ST group) and oral combination of hydrocortisone sodium succinate and aluminum phosphate gel (OHA group). Stricture rate was compared between the two groups. Results There were six and seven complete and ≥3/4 circular ESD cases, respectively, in the IT+ST group and four and ten cases in the OHA group. Stricture rates in the IT+ST and OHA groups were 53.8% and 7.1%, respectively. Nine patients in each group developed hypokalemia after glucocorticoid administration. Conclusions OHA is a promising treatment strategy for stricture prevention following large-circumference ESD in patients with early stage esophageal carcinoma.

Published: December 2019

Objective To investigate the effect of propofol on the expression and phosphorylation of the skeletal muscle insulin receptor and its substrates following hepatic ischemia-reperfusion injury (HIRI). Methods Sixty healthy Wistar rats were divided randomly into a propofol group (P) and an ischemia-reperfusion group (I/R). Rats in the P group received propofol infusion prior to ischemia and during a 120-minute post-reperfusion period. Plasma glucose and insulin concentrations were measured, as well as expression levels of the insulin signaling proteins insulin receptor (IR) β unit (IRβ) and IR substrate 1 (IRS-1). In addition, tyrosine phosphorylation levels of these proteins were measured in skeletal muscle. Results Plasma glucose levels in the two groups were higher at 2 hours after reperfusion (T2) versus exposure of the hepatic hilum (T1). Plasma glucose levels in the I/R group were higher than those in the P group, while insulin levels at T2 were lower. In addition, phosphotyrosine levels of IRβ and IRS-1 were decreased by 32.1% and 22.4%, respectively. Conclusion Propofol increased phosphotyrosine levels of IRβ and IRS-2, resulting in an alleviation of increased plasma glucose levels following HIRI.

Objective To investigate the in vitro cytocompatibility and osteogenic potential of an experimental calcium silicate-based cement and the inflammatory response in human periodontal ligament stem cells (hPDLSCs). Methods Cellular responses, osteogenic-related gene expression, and the production of inflammatory cytokines including interleukin (IL)-6 and IL-8 were studied in hPDLSCs exposed to the experimental root canal-filling material C-Root, the commercial tricalcium silicate-based material BioRoot RCS, and the epoxy resin-based material AH Plus. Differences were analyzed using one-way ANOVA with Bonferroni-adjusted pairwise comparison. Results Exposure to BioRoot and C-Root caused time-dependent increases in cell proliferation. Significantly more mineralized nodules were formed in cells exposed to AH Plus and BioRoot compared with the negative control. Alkaline phosphatase (ALP) activity was significantly lower in AH Plus cells compared with negative control, BioRoot, and C-Root cells. ALP, osteocalcin (OCN), and runt-related transcription factor2 (RUNX2) mRNA expression levels were all significantly higher in C-Root compared with AH Plus cells at day 7. IL-6 and IL-8 levels differed significantly among the experimental groups, with the highest IL-8 levels in BioRoot cells at days 7 and 14. Conclusion The experimental root canal-filling material C-Root has similar in vitro cytocompatibility to BioRoot and better osteogenic potential than AH Plus.

Published: December 2019

Objective The objective was to investigate the frequency and type of chromosomal abnormalities and Y chromosome microdeletions in infertile men with azoospermia and oligozoospermia to ensure appropriate genetic counseling before assisted reproduction in Eastern China. Methods A total of 201 infertile men (148 with azoospermia and 53 with oligozoospermia) were enrolled. Real-time PCR using six Y-specific sequence-tagged sites of the azoospermia factor (AZF) region was performed to screen for microdeletions. Karyotype analyses were performed on peripheral blood lymphocytes with standard G-banding. Results Out of 201 infertile patients, 22 (10.95%) had Y microdeletions [17/148 (11.49%) men with azoospermia and 5/53 (9.43%) men with oligozoospermia]. The most frequent microdeletions were in the AZFc region, followed by the AZFa+b + c, AZFb+c, AZFa, and AZFb regions. Chromosomal abnormalities were detected in 18.91% (38/201) of patients, 34 of which were sex chromosome abnormalities (16.92%) and 4 of which were autosomal abnormalities (1.99%). Chromosomal abnormalities were more prevalent in men with azoospermia (22.97%) than in those with oligozoospermia (7.55%). Conclusions We detected a high incidence of chromosomal abnormalities and Y chromosomal microdeletions in infertile Chinese men with azoospermia and oligozoospermia. These findings suggest the need for genetic testing before the use of assisted reproduction techniques.

Authors: Zhang Dongliang , Zhang Zhoucang , Wan Li , Chang Jingjing , Zhao Rui 
Published: December 2019

Target: To compare the ultrasound characteristics between functional, mature arteriovenous fistulas and functional, non-mature arteriovenous fistulas and to identify the predictors of arteriovenous fistula maturation in the forearm. Methods: Patients with newly set-up functional arteriovenous fistulas were enrolled in this prospective cohort study. Ultrasound examinations were conducted pre-operatively and post-operatively. The inner vessel diameter, blood flow volume, and resistance index were measured and compared between the maturation group (Group M) and non-maturation group (Group N). Baseline parameters were calculated to determine the predictors of non-maturation of arteriovenous fistulas. Results: All 52 patients with functional arteriovenous fistulas, who were categorized into Group M (25 patients, 48.08%) and Group N (27 patients, 51.92%), finished 24 weeks of follow-up after arteriovenous fistula surgery. The arteriovenous fistulas displayed a significant and rapid increase in the vessel diameter (mean increase of 1.34 times in the arteries and 1.92 times in the veins) and blood flow volume (mean increase of 9.29 times of the arteries and 43.66 times of the veins) and a decrease in the resistance index (mean decrease in 48.00% in the arteries) 8 weeks after surgery. Group N had a lesser increase in the vessel diameters (1.78 times vs 2.06 times, t = −3.136, p = 0.003) and blood flow volume (33.98 times vs 54.11 times, t = −2.383, p = 0.021) of the cephalic vein draining segments (a6) than Group M. The baseline diameter of a6 was the only independent predictor (regression coefficient = 26.229, p = 0.008) of maturation of the functional arteriovenous fistulas after correcting for sex, age, diabetes kidney disease, weight, and height. Conclusion: The baseline diameter of the cephalic vein was the only predictor of arteriovenous fistula maturation based on the pre-operative ultrasound measurements in Chinese hemodialysis patients.

Published: December 2019

Background and Aims: The interpositional arthroplasty was developed to retain foot function and to relieve pain due to the arthritis of the first metatarsophalangeal joint. The bioabsorbable poly-L-D-lactic acid RegJoint® interpositional implant provides temporary support to the joint, and the implant is subsequently replaced by the patient’s own tissue. In this study, we retrospectively examined the results of the poly-L-D-lactic acid interpositional arthroplasty in a 9-year follow-up study among patients with hallux valgus with end-stage arthrosis or hallux rigidus. Material and Methods: Eighteen patients and 21 joints underwent interpositional arthroplasty using the poly-L-D-lactic acid implant between February 1997 and October 2002 at Tampere University Hospital. Of these, 15 (83.3%) (21 joints) patients were compliant with clinical examination and radiographic examination in long-term (average 9.4 years) follow-up. The mean age of the patients was 48.3 (from 28 to 67) years at the time of the operation. Six patients underwent the operation due to arthritic hallux valgus and nine patients due to hallux rigidus. Results: The mean Ankle Society Hallux Metatarsophalangeal–Interphalangeal Scale and visual analogue scale (VAS) for pain scores improved after the operation in all patients. The decrease of pain (visual analogue scale) after the operation was statistically significant (77.5 vs 10.0; p < 0.001). Postoperative complications were observed in 3 (14.3%) joints of two hallux rigidus patients. For these patients, surgery had only temporarily relieved the pain, and they underwent reoperation with arthrodesis. Conclusion: In conclusion, interpositional arthroplasty using a poly-L-D-lactic acid implant yielded good results. This study indicates that the poly-L-D-lactic acid interpositional implant may be a good alternative for arthrodesis for treatment of end-stage degeneration of the first metatarsophalangeal joint.
Expedited TR Band Removal for Transradial Approach for Noncoronary Visceral Procedures: Initial Experience
Authors: Shahid Muhammad , Chandra Vishnu , Wajswol Ethan , Contractor Sohail , Shukla Pratik , Kumar Abhishek 
Published: December 2019

Purpose: For transradial interventions, most published studies report an initial Terumo Radial (TR) band placement time of 60 minutes, with gradual deflation over 30 to 90 minutes. We aimed to determine, retrospectively, whether TR band removal time could be expedited to 45 to 60 minutes, without adverse effects via an expedited single-step deflation protocol. Methods: A total of 115 consecutive noncoronary visceral interventions that utilized TR band from September 2017 till February 2019 were retrospectively reviewed. Alternative single-step deflation protocol was utilized where the nursing staff was instructed to deflate the TR band in 1 step between 45 and 60 minutes; 79 patients (43 men, 36 women, mean age of 55.3 ± 13.6 years) underwent 115 transradial interventions. Mean procedure time was 49.8 ± 22.1 minutes, and mean fluoroscopy time was 18.5 ± 10.6 minutes. Data collected included patient demographics, procedure details, and nursing notes on complications including bleeding and reinflation of the TR band. Univariate and Multivariate analyses of independent variables were performed using a binary logistic regression model. All patients were followed up postoperatively before discharge and in clinic upon follow-up. Results: The TR band was deflated at 51.3 ± 14.5 minutes, with successful removal achieved on the first attempt in 103 cases (90.3% primary technical success rate). In 12 cases, bleeding was noted upon initial deflation, secondary technical success was achieved when the band was reinflated for an additional mean time of 37.0 ± 19.1 minutes. There was 1 incidence of radial artery occlusion (0.8%) and 1 incidence of a grade 1 hematoma (0.8%). The only variable predictive of technical outcome upon initial band deflation on univariate binomial logistic regression was initial TR band removal time ( P = .019). Conclusions: A single-step deflation protocol for TR band placement may be safe for nonocclusive patent hemostasis and may translate to even further shorten postprocedural hospital times for patients and cost savings for hospitals.

Background: First-line treatments for nonsmall cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations have been evaluated in various clinical trials. However, it remains unclear which is the optimal treatment. Methods: A Bayesian network meta-analysis was used to assess the efficacy and safety profile of gefitinib, erlotinib, afatinib, dacomitinib, osimertinib, erlotinib plus bevacizumab and pemetrexed/carboplatin, or pemetrexed alone plus gefitinib. Literature was sourced from electronic databases. Data regarding objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), treatment-related adverse events (TRAEs), treatment-related adverse event grades 3–5 (TRAE 3–5), specific TRAEs [diarrhea, rash, and elevated aspartate aminotransferase/alanine aminotransferase (AST/ALT)] were extracted. The regimens were then ranked using the surface under the cumulative ranking curve (SUCRA). Results: A total of 19 studies involving 4607 EGFR-mutant NSCLC patients were analyzed. In regards to efficacy, pemetrexed/carboplatin (PC) plus gefitinib was superior in ORR and OS to chemotherapy and first-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs). All the TKI-based regimens had equivalent DCR and PFS. Patients with the L858R mutation treated with PC plus gefitinib achieved a better outcome than most EGFR TKI-related groups (except osimertinib) in the PFS subgroup. In regards to safety, no statistical significance for TRAEs was observed among the eight treatments. In regards to SUCRA, PC plus gefitinib ranked first in terms of PFS, OS, and TRAE grades 3–5. Conclusions: Pemetrexed/carboplatin plus gefitinib is a promising treatment option for EGFR-mutant NSCLC patients in the first-line setting.
We Agree, Don’t We? The Delphi Method for Health Environments Research
Authors: Taylor Ellen 
Published: December 2019

Objective: This overview is intended to provide the process framework for built environment researchers to use the Delphi method. The article outlines the methodological criteria originally established for the Delphi method, as well as commonly accepted modifications, to advance guidance for evidence-based built environment considerations. Background: Increasingly used in healthcare research, the Delphi method is a process for gaining consensus through controlled feedback from a panel—a group made up of experts or individuals knowledgeable on the subject. The method is often used where there is limited or conflicting evidence, where participants may be geographically dispersed, and where anonymity is desired to control for dominant individuals. The Delphi method consists of panel selection, development of content surveys, and iterative stages of anonymous responses to gain consensus. Panelists receive feedback after each round in the form of a statistical representation of the overall group’s response. The goal of multiple iterations in the Delphi method is to reduce the range of responses and gain expert consensus, which is often seen as more credible than conjecture or individual opinion. Conclusion: With a geographic diversity of healthcare design expertise, and with so many aspects of healthcare design lacking a robust body of supporting empirical research, the Delphi method is well-suited to developing evidence-based design recommendations and considerations for healthcare built environments.
PEIS: a novel approach of tumor purity estimation by identifying information sites through integrating signal based on DNA methylation data
Authors: Wang Shudong , Wang Lihua , Zhang Yuanyuan , Pang Shanchen , Wang Xinzeng 
Published: December 2019

Abstract
Background
Tumor purity plays an important role in understanding the pathogenic mechanism of tumors. The purity of tumor samples is highly sensitive to tumor heterogeneity. Due to Intratumoral heterogeneity of genetic and epigenetic data, it is suitable to study the purity of tumors. Among them, there are many purity estimation methods based on copy number variation, gene expression and other data, while few use DNA methylation data and often based on selected information sites. Consequently, how to choose methylation sites as information sites has an important influence on the purity estimation results. At present, the selection of information sites was often based on the differentially methylated sites that only consider the mean signal, without considering other possible signals and the strong correlation among adjacent sites.

Results
Considering integrating multi-signals and strong correlation among adjacent sites, we propose an approach, PEIS, to estimate the purity of tumor samples by selecting informative differential methylation sites. Application to 12 publicly available tumor datasets, it is shown that PEIS provides accurate results in the estimation of tumor purity which has a high consistency with other existing methods. Also, through comparing the results of different information sites selection methods in the evaluation of tumor purity, it shows the PEIS is superior to other methods.

Conclusions
A new method to estimate the purity of tumor samples is proposed. This approach integrates multi-signals of the CpG sites and the correlation between the sites. Experimental analysis shows that this method is in good agreement with other existing methods for estimating tumor purity.
