Assessment of skin-related toxicity in patients with metastatic colorectal cancer treated with cetuximab

Monoclonal antibodies (mAbs) blocking the epidermal growth factor receptor (EGFR) pathway, such as cetuximab, have been widely used in recent years for the treatment of metastatic colorectal cancer (mCRC). The purpose of this study was to evaluate the profile of the side effects of cetuximab affecting the skin and its appendages. We gathered the medical records on skin-related toxicity in 46 patients treated with cetuximab for mCRC in the Department of Clinical Oncology, University Hospital in Krakow in 2009-2013. Skin toxicity was classified according to the National Cancer Institute Common Toxicity Criteria for Adverse Events version 4.0. The typical side effects of cetuximab were observed. The most common skin toxicity was an acne-like skin rash (80% of patients) and paronychia (20%). Other side effects were trichomegaly, hypertrichosis, and allergic reactions.In view of high incidence of skin lesions during treatment with cetuximab, it is essential to observe patients carefully and to control the side effects during therapy. Previous experience from clinical trials shows that in some cases proper care and prevention can improve the quality of the patients’ lives.</p

In vivo performance of hierarchical HRP-crosslinked silk fibroin/β-TCP scaffolds for osteochondral tissue regeneration

Background: Osteochondral defects (OCD) can affect the articular cartilage and subchondral bone tissues, which requires superior therapies for the simultaneous and full restoration of such structurally and biologically different tissues. Methods: Tissue engineered OC grafts were prepared using a horseradish peroxidase (HRP) approach to crosslink silk fibroin (HRP-SF) as the articular cartilage-like layer and an underlying HRP-SF/ZnSrTCP subchondral bone-like layer (HRP-SF/dTCP), through salt-leaching/freeze-drying methodologies. In vivo OC regeneration was assessed by implantating the hierarchical scaffolds in rabbit critical size OC defects, during 8 weeks. A comparative analysis was performed using hierarchical OC grafts made of pure β-TCP (HRP-SF/TCP). Results: The hierarchical scaffolds showed good integration into the host tissue and no signs of acute inflammatory reaction, after 8 weeks of implantation. The histological analyses revealed positive collagen type II and glycosaminoglycansâ formation in the articular cartilage-like layer. New bone ingrowthâ s and blood vessels infiltration were detected in the subchondral bone-like layers. Conclusions: The proposed hierarchical scaffolds presented an adequate in vivo response with cartilage tissue regeneration and calcified tissue formation specially promoted by the ionic incorporation into the subchondral bone layer, confirming the hierarchical structures as suitable for OCD regeneration.Portuguese Foundation for Science and Technology for the Hierarchitech project (M-era-Net/0001/2014), for the fellowships (SFRH/BD/99555/2014) and (SFRH/BPD/101952/2014), and for the distinctions attributed to JMO (IF/01285/2015) and SP (CEECIND/03673/2017).

Measurement and comparison of individual external doses of high-school students living in Japan, France, Poland and Belarus -- the "D-shuttle" project --

Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter "D-shuttle" for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the background radiation level of other regions/countries

The Role of Purported Mucoprotectants in Dealing with Irritable Bowel Syndrome, Functional Diarrhea, and Other Chronic Diarrheal Disorders in Adults

Chronic diarrhea is a frequent presenting symptom, both in primary care medicine and in specialized gastroenterology units. It is estimated that more than 5% of the global population suffers from chronic diarrhea. and that about 40% of these subjects are older than 60 years. The clinician is frequently faced with the need to decide which is the best therapeutic approach for these patients. While the origin of chronic diarrhea is diverse, impairment of intestinal barrier function, dysbiosis. and mucosal micro-inflammation are being increasingly recognized as underlying phenomena characterizing a variety of chronic diarrheal diseases. In addition to current pharmacological therapies, there is growing interest in alternative products such as mucoprotectants, which form a mucoadhesive film over the epithelium to reduce and protect against the development of altered intestinal permeability, dysbiosis, and mucosal micro-inflammation. This manuscript focuses on chronic diarrhea in adults, and we will review recent evidence on the ability of these natural compounds to improve symptoms associated with chronic diarrhea and to exert protective effects for the intestinal barrier

The ESSnuSB design study: overview and future prospects

ESSnuSB is a design study for an experiment to measure the CP violation in the leptonic sector at the second neutrino oscillation maximum using a neutrino beam driven by the uniquely powerful ESS linear accelerator. The reduced impact of systematic errors on sensitivity at the second maximum allows for a very precise measurement of the CP violating parameter. This review describes the fundamental advantages of measurement at the 2nd maximum, the necessary upgrades to the ESS linac in order to produce a neutrino beam, the near and far detector complexes, the expected physics reach of the proposed ESSnuSB experiment, concluding with the near future developments aimed at the project realization.Comment: 19 pages, 11 figures; Corrected minor error in alphabetical ordering of the authors: the author list is now fully alphabetical w.r.t. author surnames as was intended.

The Different Function of Single Phosphorylation Sites of Drosophila melanogaster Lamin Dm and Lamin C

Lamins' functions are regulated by phosphorylation at specific sites but our understanding of the role of such modifications is practically limited to the function of cdc 2 (cdk1) kinase sites in depolymerization of the nuclear lamina during mitosis. In our study we used Drosophila lamin Dm (B-type) to examine the function of particular phosphorylation sites using pseudophosphorylated mutants mimicking single phosphorylation at experimentally confirmed in vivo phosphosites (S25E, S45E, T435E, S595E). We also analyzed lamin C (A-type) and its mutant S37E representing the N-terminal cdc2 (mitotic) site as well as lamin Dm R64H mutant as a control, non-polymerizing lamin. In the polymerization assay we could observe different effects of N-terminal cdc2 site pseudophosphorylation on A- and B-type lamins: lamin Dm S45E mutant was insoluble, in contrast to lamin C S37E. Lamin Dm T435E (C-terminal cdc2 site) and R64H were soluble in vitro. We also confirmed that none of the single phosphorylation site modifications affected the chromatin binding of lamin Dm, in contrast to the lamin C N-terminal cdc2 site. In vivo, all lamin Dm mutants were incorporated efficiently into the nuclear lamina in transfected Drosophila S2 and HeLa cells, although significant amounts of S45E and T435E were also located in cytoplasm. When farnesylation incompetent mutants were expressed in HeLa cells, lamin Dm T435E was cytoplasmic and showed higher mobility in FRAP assay

Determinants of ergonomics work of women

Celem pracy jest przeanalizowane wybranych determinant ergonomicznej pracy kobiet, w porównaniu do odpowiednio zatrudnianych mężczyzn oraz wskazanie kierunków usprawnień. Należy zauważyć, że zakres pracy wykonywanej przez kobiety w większości przypadków różni się od pracy zlecanej mężczyznom. Wśród kobiet charakteryzujących się wyższym wykształceniem, wskaźnik zatrudnienia jest znacznie mniejszy niż mężczyzn. Kobiety podejmują pracę przede wszystkim lekką, średnio ciężką, natomiast ciężką i średnio ciężką wykonują mężczyźni. W analizie zatrudnienia, zwrócono również uwagę na dyskryminację kobiet. Obecnie dostrzega się za to wzrost wskaźnika aktywności zawodowej zarówno wśród kobiet, jak i mężczyzn. Czas pracy oraz zakres i sposób zlecanych czynności pracującym zawodowo kobietom, a zwłaszcza samotnie wychowującym dzieci powinien być ściśle dostosowywany do ich potrzeb i możliwości psychofizycznych, co powinno być zgodne z zasadami ergonomii.The paper analyzed the selected determinantas of ergonomics work related to employ the women, compared to men employed respectively. It should be noted that the scope of work performed by women in most cases is different from the work for men. Among women with higher education, the employment rate is much lower than for men. Women take mainly light and medium duty, while men do the hard and medium-hard work. Analysis of employment also focuses attention on discrimination against women. Currently, there is an increase in professional activity among both women and men. Working time, the scope and manner of tasks entrusted to working women, especially single parents, should be closely tailored to their needs and psycho-physical capabilities which should be consistent with the principles of ergonomics
