775; 95% confidence interval (CI) 0.658-0.867], sensitivity 100% (95% CI 83.9-100), specificity 48.9% (95% CI 34.1-63.9) (P less then 0.001). Advanced maternal age and higher L levels were found to be predictive factors [odds ratio (OR)=1.16 and OR=1.06, respectively] independently associated with gestational diabetes. In as far as general factors are concerned, the patient BMI (body mass index) at the beginning of the pregnancy and smoking were found to be the main risk factors for the onset of GDM. This study showed that elevated L levels are a strong predictor of GDM, while AN and CMPF levels are not, as they failed to show a significant association.The present study investigated the effects of the COVID-19 pandemic on the clinical presentation and therapeutic management of acute surgical abdomen. A retrospective study of emergency hospitalizations with a diagnosis of acute surgical abdomen between April and July 2020 vs. a similar period in 2019 was performed. The observation sheets and the operating protocols were analyzed. Between April and July 2020, 50 cases of acute surgical abdomen were hospitalized and treated, compared to 43 cases in the same period last year. The main types of pathology in both groups included Occlusions (60%, respectively 44.2% in 2019) and peritonitis (32%, respectively 41.8% in 2019). There was an increased rate of patients with colorectal cancers neglected therapeutically or uninvestigated, who presented during the pandemic period with emergencies for complications such as occlusion or tumor perforation (32 vs. Curzerene 6.97%, P=0.0039). One case, with gastric perforation, was COVID-positive, with no pulmonary symptoms at admission. The number of postoperative infectious complications was lower during the pandemic (2 vs. 13.95%, P=0.0461). As the COVID-19 pandemic appears to be still far from ending, we should learn to adapt our surgical protocols to the new evidence. Oncological patients are a vulnerable group, who were neglected in the first months of the pandemic. SARS-Cov-2 infection may be a cause of abdominal pain and should be taken into account in different diagnoses of acute abdomen in surgical wards. Correct wearing of adequate personal protective equipment (PPE) and respecting strict rules of asepsis and antisepsis are required for preventing in-hospital transmission of infection.Non-small cell lung cancer (NSCLC) is a common malignancy associated with poor clinical outcomes and high mortality rate. The association between NSCLC development and long non-coding RNA (lncRNA) expression remains to be elucidated. The current study investigated the role of a novel lncRNA, receptor activator of nuclear factor-κ B ligand (RANKL), in the resistance of NSCLC to chemotherapy. RANKL expression was assessed via reverse transcription-quantitative PCR, cell death rate was evaluated using flow cytometry and sensitivity of cisplatin (DDP)-resistant A549/DDP cells to chemotherapy was determined using the Cell Counting Kit-8 assay. Western blotting was performed to quantify p53 protein levels. Compared with matched A549 cells, A549/DDP cells exhibited significant upregulation of RANKL expression. Sensitivity of A549/DDP cells to DDP was restored following RANKL knockdown. A549 cells overexpressing RANKL exhibited notably impaired DDP sensitivity compared with controls. Conversely, downregulated RANKL expression triggered cell death and inhibited cell migration via p53 stimulation and phosphatidylinositol 3-kinase/protein kinase B pathway suppression. The current findings indicate that RANKL contributes to DDP resistance in NSCLC and may represent a novel therapeutic target in this malignancy.[This corrects the article DOI 10.3892/etm.2019.7737.].The purpose of the present study was to explore the relationship between nuclear factor erythroid 2-related factor 2 (Nrf2)/BTB-CNC allogeneic 1 (Bach1)/γ-glutamic acid cysteine synthase (γ-GCS) and chronic obstructive pulmonary disease (COPD). The expression of Nrf2, Bach1, γ-GCS mRNA and protein in the peripheral blood mononuclear cells (PBMCs) of 80 COPD patients and 40 healthy volunteers were studied. Then, the correlation between Nrf2, Bach1, γ-GCS and lung function, inflammation and oxidative stress indicators was analyzed. Compared with healthy controls, Nrf2, Bach1 mRNA and protein levels were significantly increased in the PBMCs of COPD patients, while γ-GCS mRNA and protein levels were significantly decreased. Nrf2 and Bach1 protein levels in the nucleus were significantly elevated in acute exacerbation COPD patients compared with patients with a stable stage of COPD, while γ-GCS mRNA levels were significantly reduced. In addition, it was found that Nrf2 nuclear protein levels were significantly reduced in COPD patients compared with the control group, while Bach1 nuclear protein levels were significantly increased. Correlation analysis in COPD group demonstrated that γ-GCS mRNA was positively correlated with Nrf2 nuclear protein level, but negatively correlated with Bach1 nuclear protein level. Further analysis demonstrated that γ-GCS mRNA and Nrf2 protein in the nucleus was positively correlated with forced expiratory volume in one second (FEV1)/forced vital capacity (FVC)% and FEV1% predicted, and Bach1 protein in the nucleus was negatively correlated with FEV1/FVC% and FEV1% predicted. Additionally, the expression levels of Nrf2, Bach1 and γ-GCS were also associated with smoking. The expression of Nrf2, Bach1 and γ-GCS in peripheral blood mononuclear cells of patients with COPD was dysregulated and related to lung function, which provides a new basis for exploring further the pathogenesis of COPD.Histone modification is closely associated with several diseases. The aim of the current study was to investigate the associations among histone acetylation, matrix metalloproteinases (MMPs) and premature rupture of membranes (PROM) during pregnancy. A total of 180 puerperants were divided into three groups i) Preterm-PROM (PPROM), ii) term-PROM (TPROM) and iii) full-term labor (FTL). Enzyme-linked immunosorbent assay (ELISA) kits and western blotting were used to determine the protein concentrations of MMP2, MMP9, histone deacetylase (HDAC)1, HDAC2 and HDAC6, and the protein levels of histone H4 lysine (H4K)5 and H4K8 acetylation, respectively, in three types of fetal membranes. Additionally, human amniotic epithelial cells were used to determine the effects of the HDAC inhibitors droxinostat and chidamide on cell viability, histone acetylation and the levels of MMP2, MMP9, HDAC1, HDAC2 and HDAC6 in vitro, using the Cell Counting Kit-8 assay, western blotting and ELISA, respectively. Furthermore, the effectsimilar to that observed in TPROM. The results obtained in the current study may be used as a theoretical guide for clinical treatment of premature rupture of membranes.This case reports the result of a positive nasal swab for the SARS Antigen FIA Quidel, during the start of the realization of the antigen test, in a 26 years old asymptomatic nurse without any factors of risk who had been in contact with a COVID-19 patient three days ago. The result of the antigen test was not confirmed by the RT PCR test, which had been practiced twice. This leads us to discuss the Positive Predictive Value of the rapid tests for guidance, depending on the prevalence of the disease in the population on which they are used. This has many practical consequences for performing this test in an asymptomatic population or when used in mass screening. Care should be taken to use this test according to the correct indications.The acid-catalyzed thiol-ene reaction (ACT) is a unique thiol-X conjugation strategy that produces S,X-acetal conjugates. Unlike the well-known radical-mediated thiol-ene and anion-mediated thiol-Michael reactions that produce static thioether bonds, acetals provide unique function for various fields such as drug delivery and protecting group chemistries; however, this reaction is relatively underutilized for creating new and unique materials owing to the unexplored reactivity over a broad set of substrates and potential side reactions. Solution-phase studies using a range of thiol and alkene substrates were conducted to evaluate the ACT reaction as a conjugation strategy. Substrates that efficiently undergo cationic polymerizations, such as those containing vinyl functional groups, were found to be highly reactive to thiols in the presence of catalytic amounts of acid. Additionally, sequential initiation of three separate thiol-X reactions (thiol-Michael, ACT, and thiol-ene) was achieved in a one-pot scheme simply by the addition of the appropriate catalyst demonstrating substrate selectivity. Furthermore, photoinitiation of the ACT reaction was achieved for the first time under 470 nm blue light using a novel photochromic photoacid. Finally, using multifunctional monomers, solid-state polymer networks were formed using the ACT reaction producing acetal crosslinks. The presence of S,X-acetal bonds results in an increased glass transition temperature of 20 °C as compared with the same polymeric film polymerized through the radical thiol-ene mechanism. This investigation demonstrates the broad impact of the ACT reaction and expands upon the diverse thiol-X library of conjugation strategies towards the development of novel materials systems.
To evaluate the comparative efficacy and safety of Janus kinase (JAK) inhibitors and biological disease-modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) and an inadequate response to at least one disease-modifying antirheumatic drug (DMARD).

PubMed, Embase, Cochrane library and ClinicalTrials.gov were searched for relevant randomized controlled trials (RCTs) from inception to April 2020. The active drugs included three JAK inhibitors and eight bDMARDs while the control drugs included placebo or conventional synthetic disease-modifying antirheumatic drugs (csDMARDs). Outcomes include American College of Rheumatology 20% response (ACR20), Disease Activity Score in 28 joints (DAS28), Health Assessment Questionnaire-Disability Index (HAQ-DI) and discontinuations for adverse events (AEs). We estimated summary odds ratios (ORs) and weighted mean differences (WMDs) using network meta-analysis with random effects.

Eighty-eight RCTs with 31,566 patients were included. All JAK inARDs. RA patients taking a JAK inhibitor may have a preference for a lower recommended dose.
Tocilizumab, certolizumab pegol and upadacitinib may have relatively good efficacy in patients with RA after treatment failure with csDMARDs. RA patients taking a JAK inhibitor may have a preference for a lower recommended dose.Anti-drug antibodies can interfere with the activity of anti-tumor necrosis factor (TNF) agents by increasing drug clearance via direct neutralization. The presence of anti-drug antibodies is clinically relevant when trough drug concentrations are undetectable or sub-therapeutic. However, traditional immunoassay is not easily and rapidly accessible, making the translation of the results into treatment adjustment difficult. The availability of a point-of-care (POC) test for therapeutic drug monitoring (TDM) might represent an important step forward for improving the management of inflammatory bowel disease (IBD) patients in clinical practice. In this pilot study, we compared the results obtained with POC tests with those obtained by enzyme-linked immunosorbent assay (ELISA) in a group of IBD patients treated with Infliximab (IFX). We showed that POC test can reliably detect presence of antibody-to-IFX with 100% of specificity and 76% sensitivity, in strong agreement with the ELISA test (k-coefficient = 0.84).
