The aim of the present study based on the PriCoTTF-phase I/II trial is the quantification of skin-normal tissue complication probabilities of patients with newly diagnosed glioblastoma multiforme treated with Tumor Treating Field (TTField) electrodes, concurrent radiotherapy, and temozolomide. Furthermore, the skin-sparing effect by the clinically applied strategy of repetitive transducer array fixation around their center position shall be examined.

Low-dose cone-beam computed tomography (CBCT) scans of all fractions of the first seven patients of the PriCoTTF-phase I/II trial, used for image guidance, were applied for the dosimetric analysis, for precise TTField transducer array positioning and contour delineation. Within this trial, array positioning was varied from fixation-to-fixation period with a standard deviation of 1.1cm in the direction of the largest variation of positioning and 0.7cm in the perpendicular direction. Physical TTField electrode composition was examined and a respective Hounsfielioning increased skin-NTCP by a factor of only 3.54 (95%, CI 2.36-5.32) (P<0.0001, comparison to irradiation without electrodes; P=0.036, comparison to irradiation with fixed electrodes). NTCP showed a significant rank correlation with D25cm

over all patients and scenarios (r

=0.76; P<0.0001).

Skin-NTCP calculation uncovers significant interpatient heterogeneity and may be used to stratify patients into high- and low-risk groups of skin toxicity. Array position variation may mitigate about one-third of the increase in surface dose and skin-NTCP by the TTField electrodes.

This study aimed to review the literature on patient classification tools (PCTs) for assessing nursing strength and to compare South Korean and international tools.

Integrative literature review.

We searched the relevant literature published from 2000-2017 in PubMed and two electronic databases in Korea in March 2017. Enasidenib in vivo Twenty-five published studies were reviewed.

In most Korean studies, patients were classified by PCT, which were tested to ensure validity and reliability, followed by measurement of nursing time and development of the conversion index. In international studies, PCTs used were simpler than those in Korean studies; the results of estimation for optimum nurse staffing were reported. Most studies insufficiently reflected indirect nursing needs and patients' non-clinical factors. The current PCTs used in Korean studies inadequately reflect the reality of nursing field. Therefore, development of new PCTs reflecting nursing intensity based on direct and indirect nursing activities is necessary.

The morphological characteristics can be used for species identification of males specimens, while females are indistinguishable. Although, sandflies identification is essential to understand vectorial capacity, and susceptibility to infectious agents or insecticides, there is a lack of new strategies for specimen identification. In this study, Fourier transform infrared photoacoustic spectroscopy combined with multivariate analysis identified intraspecific differences between Lutzomyia populations. Successfully group clustering was achieved by principal component analysis. The main differences observed can be related to the protein content of the specimens. A classification with 100% accuracy was obtained using machine learning approach, allowing the identification of sandflies specimens.

The transforming growth factor-β (TGF-β) pathway plays a pivotal role in inducing epithelial-mesenchymal transition (EMT), which is a key step in cancer invasion and metastasis. However, the regulatory mechanism of TGF-β in inducing EMT in colorectal cancer (CRC) has not been fully elucidated. In previous studies, it was found that S100A8 may regulate EMT. This study aimed to clarify the role of S100A8 in TGF-β-induced EMT and explore the underlying mechanism in CRC.

S100A8 and upstream transcription factor 2 (USF2) expression was detected by immunohistochemistry in 412 CRC tissues. Kaplan-Meier survival analysis was performed. In vitro, Western blot, and migration and invasion assays were performed to investigate the effects of S100A8 and USF2 on TGF-β-induced EMT. Mouse metastasis models were used to determine in vivo metastasis ability. Luciferase reporter and chromatin immunoprecipitation assay were used to explore the role of USF2 on S100A8 transcription.

To examine whether real-world clinical patients with macular oedema (MO) receiving intravitreal antivascular endothelial growth factor (VEGF) therapy have a higher mortality compared with a matched reference population.

A population-based, retrospective cohort study of 26 386 patients from Finland, from January 1, 2001, to December 31, 2017. Index patients were identified through the Caring Epidemiology Project database, receiving at least one intravitreal anti-VEGF injection for wet age-related macular degeneration (AMD, n=2243, 48.61%), diabetic MO (n=744, 16.12%), MO due to retinal vascular occlusion (n=589, 12.77%), or other MO (n=1038, 22.5%). For each individual treated with intravitreal injection (n=4614), five age- , sex- , calendar year- and hospital district- matched control individuals (n=21 772) were chosen. Baseline data of chronic conditions were available. All-cause and cause-specific mortality was analysed using Cox´s proportional hazards model.

In general, the anti-VEGF treated patients had a higher prevalence of systemic conditions, including diabetes (60.
