    AbstractBackground/purposeThe purposes of this in vitro study were to determine the microtensile bond strengths of four different dentin adhesive materials placed in pulp chamber walls, and to test the effects of 5% sodium hypochlorite (NaOCl) and 17% ethylenediaminetetraacetic acid (EDTA) pretreatments on resin dentin bond strengths.Materials and methodsRecently extracted human third molars were selected. The teeth were divided into four groups. Specimens in each group were treated as follows: irrigated with distilled water; irrigated with EDTA for 5 minutes; irrigated with sodium hypochlorite for 5 minutes; and irrigated with EDTA for 5 minutes followed by NaOCl for 5 minutes. Treated specimens were dried, bonded with a total-etching adhesive, two self-etching adhesives, or a one-bottle self-etching adhesive system. After the bonding procedure and composite restoration, teeth were sectioned, and 15 dentin sticks were obtained. Microtensile testing was performed, and scanning electron micrographs were taken of each irrigated group.ResultsIn the control group, the one-bottle self-etching adhesive system showed statistically higher bond strength values. EDTA irrigation did not affect the bond strength except for the total-etching adhesive. NaOCl significantly reduced the bond strengths of all adhesives. The EDTA and NaOCl combination did not show a statistically significant reduction in bond strengths of the adhesives to pulpal dentin.ConclusionThere was a reduction in bond strengths of all adhesive systems used to test pulp chamber lateral walls after endodontic irrigation solutions were used

    We compared standard and patient-targeted in-patient education in terms of their effect on patients' anxiety. One hundred and ninety-eight patients who were hospitalised for coronary artery bypass surgery were given standard education (group 1) or individualised education (group 2) on the management of their healthcare after discharge. Patients in group 2 were assessed on the patient learning needs scale and were given education according to their individual needs. The level of anxiety was measured by the state-trait anxiety inventory. Anxiety scores were significantly lower in group 2 than group 1 after education (p < 0.001). While state anxiety did not change after education in group 1 (p = 0272), it decreased significantly in group 2 (p < 0.001). For cardiovascular surgery patients, patient-targeted in-patient education was more effective than standard education in decreasing anxiety levels, therefore the content of the education should be individualised according to the patient's particular needs

    Background: Immunotherapy agents such as atezolizumab and nivolumab are appropriate option for non-small cell lung cancer (NSCLC) accounts in the absence of driver mutation, regardless of PDL-1 expression in second and later line setting. Herein we aimed to evaluate the efficacy and safety of immunotherapy for the second and later line settings in metastatic NSCLC patients as a single center experience. Methods: Totally, 37 patients with metastatic NSCLC who received atezolizumab or nivolumab in the second or later lines were included. Clinicopathological features of patients and survival outcomes were analyzed. The safety profile and the factors that may predict survival were also evaluated. Results: Twenty-nine (78.4%) of patients were men and 8 of patients (21.6%) were woman with median age of 61 years (range:42-80). Atezolizumab was preferred in 22 (59.5%) of these patients and nivolumab in 15 (40.5%) of them. Objective response rate was 35.1%. At a median follow up of 22.5 months, median progression-free survival (PFS) was 4.7 months, median overall survival (OS) was 24.1 months. Univariate analysis for PFS revealed that gender (p=0.03), age (p=0.005), the presence of brain metastasis (p=0.02), PDL-1 status >1% (p=0.035), ECOG PS (p=0.04) and the good response to frontline treatment (p=0.015) were found to be significant prognostic indicators. It also showed that the presence of brain metastasis (p=0.03), PDL-1 status >1% (p=0.027), good response to frontline treatment (p=0.022) and atezolizumab preference (p=0.018) were prognostic factors for OS.

    Aim. We aimed to compare the local therapeutic efficiency of microwave ablation (MWA), surgical resection, and combined treatment, assess the outcomes, and identify predictive factors for local treatment response in colorectal liver metastases (CLMs). Methods. From March 2013 to September 2019, a total of 54 patients with 302 CLMs were enrolled in this retrospective study. Eleven patients (20.4%) were treated with MWA, 9 patients (16.7%) with surgery, and 34 patients (63%) with the combined method. Univariate and multivariate analyses were performed to investigate overall survival (OS) and hepatic progression-free survival (HPFS) using the Cox proportional hazard regression model. The logistic regression analysis was used to identify the predictive factors for the local treatment response. Results. Total treatment response was achieved in 46.3% (n=25) of the patients. Local tumor progression was seen in 7.4% (n=4) of the patients, and the rate of intrahepatic distal recurrence was 46.3% (n=25). There were no significant differences in HPFS and OS between the three groups (p=0.56 and 0.90, respectively). Younger age

    Metaproteogenomic analysis of saliva samples from Parkinson's disease patients with cognitive impairment

    Cognitive impairment (CI) is very common in patients with Parkinson's Disease (PD) and progressively develops on a spectrum from mild cognitive impairment (PD-MCI) to full dementia (PDD). Identification of PD patients at risk of developing cognitive decline, therefore, is unmet need in the clinic to manage the disease. Previous studies reported that oral microbiota of PD patients was altered even at early stages and poor oral hygiene is associated with dementia. However, data from single modalities are often unable to explain complex chronic diseases in the brain and cannot reliably predict the risk of disease progression. Here, we performed integrative metaproteogenomic characterization of salivary microbiota and tested the hypothesis that biological molecules of saliva and saliva microbiota dynamically shift in association with the progression of cognitive decline and harbor discriminatory key signatures across the spectrum of CI in PD. We recruited a cohort of 115 participants in a multi-center study and employed multi-omics factor analysis (MOFA) to integrate amplicon sequencing and metaproteomic analysis to identify signature taxa and proteins in saliva. Our baseline analyses revealed contrasting interplay between the genus Neisseria and Lactobacillus and Ligilactobacillus genera across the spectrum of CI. The group specific signature profiles enabled us to identify bacterial genera and protein groups associated with CI stages in PD. Our study describes compositional dynamics of saliva across the spectrum of CI in PD and paves the way for developing non-invasive biomarker strategies to predict the risk of CI progression in PD.FEMS Research and Training Gran

    WOS: 000354498503198OBJECTIVES: Sorafenib is the first product approved for treatment of RAI refractory locally advanced/metastatic DTC patients. This study was conducted in order to analyze cost-effectiveness of sorafenib for treatment of patients with RAI refractory locally advanced/metastatic DTC in Turkey. METHODS: A cohort partition model assigning patients to one of three health states according to the proportion of patients who are progression-free, progressed, or dead in each 28-days cycle was adapted to Turkish setting. The incremental cost-effectiveness ratios (ICER) were calculated per quality-adjusted life years (QALYs) and life-years (LYs) gained. Turkish payer’s perspective was taken and time-horizon was set as patient’s lifetime (maximum 30 years). Sorafenib was compared to the best supportive care (BSC) within the model since there are no agents for treatment of patients on this stage of the disease. Essential clinical inputs were derived from DECISION trial and local resource-utilization data were based on expert opinions through an expert panel. Sensitivity of the results was evaluated in terms of key inputs by deterministic oneway and probabilistic sensitivity analyses. All costs were calculated in Turkish Liras (TL) and converted to USD using TL/USD currency rate as 2.2 (mid-2014). RESULTS: Total cost of sorafenib-treated patients is 24,384 USD higher compared to BSC. Besides, sorafenib is associated with increments of 1.29 LYs and 0.80 QALYs compared to BSC. The ICER of sorafenib per LYs and QALYs gained compared to BSC were determined as 18,851 USD and 30,485 USD respectively. One-way sensitivity analysis demonstrated that results are not sensitive to the changes in model inputs and pharmacoeconomic analysis results were validated by probabilistic sensitivity analysis. CONCLUSIONS: Sorafenib is cost-effective for treatment of patients with RAI refractory locally advanced/metastatic DTC compared to BSC with an ICER value below the willingness-to-pay threshold (3-times GDP per capita ─ 32,346 USD) for Turkey

    PURPOSEWe aimed to test the null hypothesis that relative apparent diffusion coefficient (rADC) and relative signal intensity values (rSIHASTE) do not change in the evaluation of placental maturation with advancing gestational age.MATERIALS AND METHODSFifty-six fetuses with diffusion-weighted magnetic resonance imaging (DW-MRI) data were enrolled in this retrospective study. Fetuses were analyzed in three different gestational age groups: group 1, 18–23 weeks; group 2, 24–28 weeks; and group 3, 29–38 weeks. The rADC (mean ADC/ADCglobe) and rSIHASTE values (mean SIHASTE/SIglobe) were obtained. Two radiologists experienced in fetal MRI who were blinded to the patient information reviewed MRI images independently. Kruskal-Wallis Test was used to compare the rADC and rSIHASTE with gestational age groups. The agreement between the two blinded readers was tested using Krippendorff’s alpha ratio.RESULTSBoth placental rADC values and placental rSIHASTE values were not significantly different between the gestational age groups (P = 0.688 and P = 0.280, respectively). rADC and rSIHASTE measurements were reproducible with a good agreement between the two readers (Krippendorff’s alpha ratio was 0.613 and 0.778, respectively).CONCLUSIONThe rADC and rSIHASTE values do not change with advancing gestational age
