More specifically, 42 (73.0%) patients presented postswallow vallecular residue, and 39 (67.9%) patients presented postswallow pyriform sinus residue. All dysphagic patients had an EAT-10 score ≥ 3. Linear regression analyses showed significant differences in mean EAT-10 scores between the dichotomized categories (abnormal vs. normal) of postswallow vallecular (P = .037) and pyriform sinus residue (P = .013). No statistically significant difference in mean EAT-10 scores between the dichotomized categories of penetration or aspiration was found (P = .966). CONCLUSION The EAT-10 questionnaire seems to have an indicative value for the presence of postswallow pharyngeal residue in dysphagic HNC patients, and a value of 19 points turned out to be useful as a cutoff point for the presence of pharyngeal residue in this study population.

Importantly, to investigate the mechanism that pyoluteorin induced human triple-negative breast cancer MDA-MB-231 cells apoptosis in vitro. METHODS The cell viability assay was tested with CTG assay. Cell cycle, apoptosis and intracellular reactive oxygen species (ROS) production assay were tested with flow cytometry. Additionally, intracellular ROS production assay and mitochondrial membrane potential assay were determined with laser scanning confocal microscopy. The expression of apoptosis-related proteins was determined with Western blot. KEY FINDINGS Pyoluteorin displayed significantly selective cytotoxicity against human triple-negative breast cancer MDA-MB-231 cells (IC50 = 0.97 µm) with low toxicity against human breast epithelial cell MCF-10A. It was found that pyoluteorin could arrest MDA-MB-231 cells cycle at G2 /M phase and induce cell apoptosis. Further experiments demonstrated that the apoptosis-inducing effect of pyoluteorin was related to reduction of mitochondrial membrane potential, accumulation of ROS and change of apoptosis-related protein expressions. CONCLUSION Our studies revealed that pyoluteorin had potent proliferation inhibition against MDA-MB-231 cells through arresting cell cycle at G2 /M phase and inducing caspase-3-dependent apoptosis by mitochondrial pathway, implying that pyoluteorin may be a potential lead compound for drug discovery of human triple-negative breast cancer. © 2020 Royal Pharmaceutical Society.OBJECTIVES The aim of this study is to compare the common cavity (CC) with the normal anatomy inner ear in order to evaluate whether the cavity is representing both the cochlear and the vestibular parts of the inner ear and to revisit CC deformity from a three-dimensional (3D) perspective. METHODS High-resolution computed tomography image datasets of 17 temporal bones initially identified as CC were evaluated with 3D reconstruction and multiplanar image analysis using a free available software for 3D segmentation of the inner ear. All 3D images of CC were compared to a normal inner ear. Maximum and minimum diameter of the CC were correlated with the circumference of the CC in an axial plane. RESULTS In 13 cases (76%), CC represented only the vestibular part of the inner ear and did not represent CC as defined here and by Sennaroglu, Kontorinis, and Khan. True CC was correctly diagnosed in only one case (6%). In three cases (18%), a rudimentary part of the cochlear portion could be identified. The axes' length of the elliptical cavity showed a strong positive linear relation to the circumference of the cavity (long axis r = 0.94; P less then .0001; short axis r = 0.68; P = .0029). CONCLUSION This study supports the assumption that many reported CC cases only represent the vestibular part of the inner ear and are therefore cases of cochlear aplasia. 3D segmentation and systematic analysis of CT-imaging add clinical value to the comprehension of the morphology of the anatomical structures of the inner ear.

Over the past decade, PBPK modeling has gained attention as a promising approach to predict drug disposition during pregnancy [1]. PBPK modeling has the advantage of incorporating both physiologic and drug-specific parameters to address a wide range of clinical questions, such as exploring the effects of drug-drug/food-drug interactions, optimizing medication dosing, providing supportive evidence for drug effectiveness, informing drug clinical trial design, and guiding regulatory policy [2]. However, there is limited use of PBPK modeling during pregnancy. For example, bictegravir (BIC) and doravidine (DOR), two new HIV medications, were both FDA-approved for use in non-pregnant adults in 2018, but these studies excluded pregnant women [3, 4].

Amoxicillin (AX), which is often prescribed alongside clavulanic acid (Clav), is the most common elicitor. The aim of this study was to determine whether AX and Clav-responsive T-cells are detectable in patients with immediate hypersensitivity to AX-Clav, to assess whether these T-cells display the same specificity as that detected in skin and provocation testing and to explore T-cell activation pathways. METHODS Drug-specific T-cell clones were generated from immediate hypersensitive patients´ blood by serial dilution and repetitive mitogen stimulation. Antigen specificity was assessed by measurement of proliferation and cytokine release. CD4+ /CD8+ and chemokine receptor expression were analyzed by flow cytometry. RESULTS 110 AX-specific and 96 Clav-specific T-cell clones were generated from 7 patients with positive skin test to either AX or Clav. Proliferation of AX- and Clav-specific clones was dose-dependent and no cross-reactivity was observed.
