M2 macrophage and Treg were positive correlated (r=0.469, p<0.001). The presence of M2 macrophage and regulatory T cell (Treg) was significantly correlated to tumor size (p= 0.091 for M2 macrophage and p=0.022 for Treg) and clinical stage (p= 0.030 for M2 macrophage and p= 0.002 for Treg), but did not correlate with lymphatic node involvement and metastasis.

In Epstein-Barr virus related NPC tumor microenvironment, the presence of M2 macrophage was correlated with Treg, and both types of the cells were correlated with tumor size and clinical stages.

HPV detection has been proposed as part of the co-testing which improves the sensitivity of cervical screening. However, the commercially liquid-based medium adds cost in low-resource areas. This study aimed to evaluate the performance of ice-cold phosphate buffer saline (PBS) for HPV detection.

HPV DNA from SiHa cells (with 1-2 copies of HPV16 per cell) preserved in ice-cold PBS or PreserveCyt solution at different time points (24, 36, 48, 72, 120 and 168 h) was tested in triplicate using Cobas 4800. The threshold cycle (Ct) values of both solutions were compared. An estimated false negative rate of PBS was also assessed by using the difference in Ct values between both solutions (∆Ct) and Ct values of HPV16-positive PreserveCyt clinical samples (Ctsample) at corresponding time points. Samples with a (Ctsample+∆Ct) value > 40.5 (the cutoff of HPV16 DNA by Cobas 4800) were considered as false negativity.

The Ct values of HPV16 DNA of SiHa cells collected in PBS were higher than PreserveCyt ranging from 0.43 to 2.36 cycles depending on incubation times. There was no significant difference at 24, 72, 120, and 168 h. However, the Ct values were statistically significantly higher for PBS than PreserveCyt at 36 h (31.00 vs 29.26), and 48 h (31.06 vs 28.70). A retrospective analysis in 47 clinical PreserveCyt collected samples that were positive for HPV16 DNA found that 1 case (2%) would become negative if collected in ice-cold PBS.

The PBS might be an alternative collecting medium for HPV detection in the low-resource areas. Further evaluations are warranted.

Breast cancer causes many psychological disorders such as sleep disturbances and depression. The current study was, therefore, intended to describe sleep quality and depression and to identify the association between these two psychological disorders among Iranian women with breast cancer.

This descriptive, analytical, cross-sectional study was carried out on 120 women with non-metastatic unilateral breast cancer undergoing chemotherapy in an outpatient chemotherapy unit of a major public hospital. A total of 120 women who had already undergone mastectomy procedure were selected via convenience sampling method. Data were collected by the Beck Depression Inventory-II (BDI-II) and the Pittsburgh Sleep Quality Index (PSQI).

The mean score on BDI-II was 13.40 (± 6.51), and 30% (n=36) of women had mild depression and 14.2% (n=17) reported moderate-to-severe depression. The mean global score of sleep quality was found to be 6.48 (± 2.62). Furthermore, 50.8% (n=61) of women obtained a global PSQI score of 5. A reported moderate-to-severe depression. The mean global score of sleep quality was found to be 6.48 (± 2.62), suggesting poor sleep quality. Furthermore, over half of the participants (50.8%) obtained a global PSQI score of 5 or greater which is indicative of poor sleep quality. A positive moderate correlation was also observed between depression and poor sleep quality.

In spite of substantial declines in both incidence and mortality rates in the past 50 years, cervical cancer remains one of the leading causes of cancer associated mortality among women globally. We performed this meta-analysis to explore the role of XRCC3 rs861539, MTHFR rs1801133, IL-6 rs1800795, IL-12B rs3212227, TNF-α rs1800629 and TLR9 rs352140 polymorphism with susceptibility to cervical carcinoma.

The search databases include PubMed, SciELO, MedRxiv, Web of Science, Scopus, Cochrane Library, China National Knowledge Infrastructure, and China Biology Medicine disc up to 30 June 2021. The language is limited to English and Chinese. GW2580 The comparison between the polymorphisms and cervical cancer was assessed using pooled odds ratio (OR) and 95% confidence interval (CI). The data are statistically analyzed by Comprehensive Meta-Analysis (CMA) 2.0 software.

A total of 59 studies including seven studies with 1,112 cases and 1,233 controls on XRCC3 rs861539, 14 studies with 2,694 cases and 3349 controls MTHFR rs1801133, four studies with 1,121 cases and 1,109 controls on IL-12B rs3212227, seven studies with 1,452 cases and 2,186 controls on IL-6 rs1800795, 20 studies with 4,781 cases and 4909 controls on TNF-α rs1800629, and seven studies with 1743 cases and 2292 controls on TLR9 rs352140 were included. There was a significant association between XRCC3 RS861539, TNF-α rs1800629, and IL-6 rs1800795 polymorphisms and an increased risk of cervical carcinoma in overall population. However, the MTHFR rs1801133, IL-12B rs3212227 and TLR9 rs352140 polymorphisms were not associated.

The pooled analysis showed that XRCC3 RS861539, TNF-α rs1800629, and IL-6 rs1800795 were associated with cervical carcinoma susceptibility, but not MTHFR rs1801133, IL-12B rs3212227 and TLR9 rs352140 polymorphisms.

Immobilization is an approach in industry to improve stability and reusability of urease. The efficiency of this technique depends on the type of membrane and the method of stabilization.

The PEI-modified egg shell membrane was used to immobilize urease by absorption and glutaraldehyde cross-linking methods. The membranes were characterized by Fourier-transform infrared spectroscopy (FTIR) and AFM, and Nessler method was applied to measure the kinetic of the immobilized enzymes. Finally, the storage stability (6 °C for 21 days) and reusability (until enzyme activity reached to zero) of the immobilized enzymes were investigated.

Based on FTIR, three new peaks were observed in both the absorption- (at 1389.7, 1230.8, and 1074.2 cm-1) and the cross-linking (at 1615-1690, 1392.7, 1450 cm-1) immobilized enzymes. The surface roughness of the native membrane was altered after PEI treatment and enzyme immobilization. The optimal pH of cross-linking immobilized enzymes was shifted to a more neutral pH, while it was alkaline in adsorption-immobilized and free enzymes. The reaction time decreased in all immobilized enzymes (100 min for free enzyme vs. 60 and 30 min after immobilizing by adsorption and cross-linking methods, respectively). The optimal temperature for all enzymes was 70 °C and they had a higher Km and a lower Vmax than free enzyme. The stability and reusability of urease were improved by both methods.

Our findings propose these approaches as promising ways to enhance the urease efficiency for its applications in industries and medicines.

Although numerous research efforts and technological advancements have focused on addressing workplace injuries, most of the studies perform empirical and deterministic postimpact evaluations on construction project performance. The effective modeling of the safety risk impacts on project performance provides decisionmakers with a valuable tool toward incidents prevention and proper safety risk management. Therefore, this study collected Australian incident records from the construction industry from 2016 onwards and conducted discrete event simulation to quantitatively measure the impact of safety risk incidents on project cost performance. Moreover, this study investigated the correlation between safety risk incidents and the age of injured workers. The findings show a strong correlation between the middle-aged workforce and the severity of incidents on project cost overruns. The ex-ante, nondeterministic analysis of safety risk impacts on project performance provides insightful results that will advance safety management theory in the direction of achieving zero harm workplace environments.

This study was performed to compare trends in home-time for patients with heart failure (HF) between those of working age and those of retirement age in Sweden from 1992 to 2012.

The National Inpatient Register (IPR) was used to identify all patients aged 18 to 84years with a first hospitalization for HF in Sweden from 1992 to 2012. Information on date of death, comorbidities, and sociodemographic factors were collected from the Swedish National Register on Cause of Death, the IPR, and the longitudinal integration database for health insurance and labour market studies, respectively. The patients were divided into two groups according to their age working age (<65years) and retirement age (≥65years). Follow-up was 4years. In total, following exclusions, 388775 patients aged 18 to 84years who were alive 1day after discharge from a first hospitalization for HF were included in the study. The working age group comprised 62428 (16%) patients with a median age of 58 (interquartile range, 53-62) years and 31led after 2007, mainly because of a lower mortality reduction in this group. Efforts to improve patient-related outcome measures specifically targeted to this group may be warranted.

A supraglottic airway device (SAD) may be utilised for rescue re-oxygenation following a failed attempt at endotracheal intubation with direct or video laryngoscopy. However, the choice of subsequent method to secure a definitive airway is not clearly established. The aim of the present study was to compare two techniques for securing a definitive airway via the in-situ SAD.

A randomised controlled trial was undertaken. The population studied was emergency physicians (EPs) attending a cadaveric airway course. The intervention was intubation through a SAD using a retrograde intubation technique (RIT). The comparison was intubation through a SAD guided by a flexible airway scope (FAS). The primary outcome was time to intubation. The trial was registered with ANZCTR.org.au (ACTRN12621000995875).

Four EPs completed intubations using both methods on four cadavers for a total of 32 experiments. The mean time to intubation was 18.2s (standard deviation 8.8) in the FAS group compared with 52.9s (standard deviation 11.7) in the RIT group; a difference of 34.7s (95% confidence interval 27.1-42.3, P < 0.001). All intubations were completed within 2min and there were no equipment failures or evidence of airway trauma.

Successful tracheal intubation of cadavers by EPs is achievable, without iatrogenic airway trauma, via a SAD using either a FAS or RIT, but was 35 s quicker with the FAS.
