This study aimed at probing into the effect of lncRNA NCK1-AS1 on proliferation, migration and invasion of non-small cell lung cancer (NSCLC) cells and its regulatory function on miR-512-5p/p21 molecular axis.

Quantitative real-time polymerase chain reaction (qRT-PCR) was used to assess the expressions of NCK1-AS1 and miR-512-5p in NSCLC tissues and cell lines. The alterations of cell proliferation, migration, invasion and cell cycle were examined by cell counting kit-8 (CCK-8) assay, BrdU experiment, Transwell experiment and flow cytometry, respectively. The dual-luciferase reporter assay and RNA immunoprecipitation experiment were performed to validate the binding relationships between miR-512-5p and NCK1-AS1, and miR-512-5p the 3'UTR of p21 mRNA. Western blot was used to determine the effects of NCK1-AS1 and miR-512-5p on p21 protein expression.

NCK1-AS1 expression was up-regulated in NSCLC tissues and cells, and its high expression was correlated with shorter overall survival time and faster progression of patients. Overexpression of NCK1-AS1 promoted NSCLC cell proliferation, migration and invasion, and accelerated the cell cycle, whereas NCK1-AS1 siRNA inhibited these malignant biological behaviors, and arrested cell cycle. NCK1-AS1 could bind to miR-512-5p, p21 was verified as a target gene of miR-512-5p, and NCK1-AS1 could up-regulate the expression of p21 in NSCLC cells via repressing miR-512-5p expression.

Patients may be afraid when they receive knowledge that medications are injected into the middle ear through the tympanic membrane using a fine needle during intratympanic treatment. The aim of this study was to evaluate the effect of video-assisted information prior to intratympanic steroid injection on patient anxiety.

Prospective, Non-randomized, controlled trial.

Tertiary academic medical center.

A total of 85 patients who had an indication for intratympanic treatment due to idiopathic sudden sensorineural hearing loss and tinnitus were included in this prospective study. 40 cases received video-assisted information before intratympanic steroid injection in the study group, while 45 cases were verbally informed face-to-face in the control group. Then, patient anxiety was measured using the Visual Analog Scale (VAS) and Spielberger State-Trait Anxiety Inventory (STAI).

The mean VAS score was 3.58±3.37 (mean rank=42.09) in the study group and 3.87±3.56 (mean rank=43.81) in the control group. The mean STAI-S score was 37.03±10.637 in the study group and 39.11±11.783 in the control group. The mean STAI-T score was 40.18±9.151 in the study group and 38.73±11.438 in the control group. It was found that there were no statistically significant differences in the mean VAS, STAI-S and STAI-T scores between the two groups (p>0.05).

We revealed that video-assisted information prior to intratympanic steroid injection had no superiority in reducing anxiety over face-to-face verbal information.

The purpose of this retrospective cohort study was to determine whether there is a difference in the sensitivity of chest computed tomography (CT) versus
F-fluorodeoxyglucose positron emission tomography with low-dose nonenhanced CT (
F-FDG PET/CT or PET/CT) in the detection of distant metastases in head and neck cancer, within a tertiary care setting.

Patients with head and neck cancer, and known distant metastases, who underwent both
F-FDG PET/CT with integrated low-dose nonenhanced CT and diagnostic chest CT prior to initiation of therapy from 2008 to 2017 were included. Two head and neck radiologists, blinded to all patient information and to each other's readings, reviewed the PET/CT or CT chest images for each patient and identified whether distant metastases were present. No radiologist read both modalities for a single patient. Concordance between imaging modalities was quantitatively analyzed using McNemar's test.

27 patients were included. McNemar's mid p-value analysis showed no significant difference in the detection of distant metastases (p=.6875). However, PET/CT detected distant metastases in three patients that chest CT did not, while chest CT identified distant metastatic disease in two patients that were negative on PET/CT.

While this study did not identify a statistically significant difference in sensitivity, five patients had distant metastases identified on only one of the two modalities. Use of a single modality would have resulted in inaccurate staging in 7-11% of patients in our study. The use of both modalities offers the greatest accuracy when providing stage-adapted oncologic treatment.

The purpose of the study was to investigate the potential correlation between plasma concentration of the newer antiseizure medication (ASM) perampanel (PMP) and both tolerability and seizure control in patients with epilepsy.

The study design was multicenter, open, and prospective. EGCG chemical structure Plasma samples were collected in the morning 12 h apart from once-a-day bedtime PMP dose. Perampanel tolerability was assessed on the day of drug monitoring by clinical examination and patients' interview. Response to PMP was defined as ≥50% reduction from baseline seizure frequency (pretreatment). The main outcomes were the comparisons of PMP plasma concentration-to-weight-adjusted dose ratio (C/D) [(μg/mL)/(mg/kg/day)] between patients with and without PMP-related adverse effects (AEs) and between responders and nonresponders.

Ninety-seven patients (54% men), mean ± SD age 36 ± 14 years were enrolled in the study. The mean PMP dose was 6.7 ± 2.3 mg, drug treatment averaged 46 ± 34 weeks. The mean plasma concentration was 360 ± 268 ng/mL (range 37-1213 ng/mL).
