B cell receptor signaling suppressor SHP-1 is active in CLL lymph node and peripheral blood
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Protein tyrosine phosphatase SHP-1 expression and activity is downregulated or lost in several leukemias and lymphomas due to DNA promotor hypermethylation, catalytic site mutation or oxidation, or phosphorylation at inhibitory sites, implying a negative role of SHP-1 in development of leukemias/lymphomas. In chronic lymphocytic leukemia (CLL), B cell receptor (BcR) and microenvironment signal levels are important in the pathogenesis. Considering that SHP-1 is a BcR signaling suppressor, we hypothesized that SHP-1 would be down-regulated and/or inactivated in the proliferative center lymph node (LN) cells. We analyzed PTPN6 (SHP-1) gene expression, SHP-1 protein expression and phosphorylation status in matched CD5+/CD19+ peripheral blood (PB) and LN cells from 6 CLL patients, and in comparison, BcR (anti-IgM) in vitro triggered CLL PB cells from 10 patients. Gene expression of PTPN6 was significantly higher in PB compared to LN CLL cells in 50% of the cases. SHP-1 protein expression level and phosphorylation at SHP-1Y536 and SHP-1S591 were, however, equal in PB and LN samples. SHP-1 phosphorylation at Y536 and S591, in PB CLL cells cultured ex vivo was significantly reduced upon BcR engagement in all patient samples. These results indicate that in vivo BcR signaling in CLL is paralyzed.

- Background: A woman's pain during labour plays a dominant role in childbirth. The midwife's role is to assess the degree of pain experienced during labour. When professionals respond to labour pain with acknowledgement and understanding, the woman's sense of control and empowerment is increased, which could contribute to a positive experience of childbirth. The aim of this study is to describe how labour pain in Swedish delivery wards is assessed and documented. Methods: This quantitative descriptive study was designed as a national survey performed through telephone interviews with the representatives of 34 delivery wards in Sweden. Results and conclusion: The majority of the participating delivery wards assessed and documented women's labour pain, but in an unstructured manner. The wards differed in how the assessments and documentation were performed. In addition, almost all the delivery wards that participated in the survey lacked guidelines for the assessment and documentation of the degree of pain during labour. The findings also showed that the issue of labour pain was sometimes discussed in the delivery wards, but not in a structured or consistent way. (C) 2015 Australian College of Midwives.

- PURPOSE: Cryopreservation of a complete ovary may be a future method for fertility preservation in cancer patients. Difficulties exist in cryopreservation of the relatively large ovarian tissue mass. This study evaluates whether a human postmenopausal ovary can be used, as a complement to animal models, in studies of this research field. METHODS: Postmenopausal human ovaries (n=10) were isolated and flushed through ovarian arteries with either the cryoprotectant dimethylsulphoxide or Ringer-Acetate, followed by slow freezing. After thawing, production of androgens during in vitro perfusion and morphology (light/electron microscopy) were assessed. RESULTS: The dimethylsulphoxide-cryopreserved ovaries showed larger secretion of androgens during perfusion than Ringer Acetate-cryopreserved ovaries. Light microscopy showed well preserved morphology in both groups. Electron microscopy revealed normal appearance of stroma and vessels in the dimethylsulphoxide group. CONCLUSIONS: The study demonstrates the potential to use the postmenopausal human ovary for further studies aiming at optimizing cryopreservation protocols, with special reference to ovarian vascularity and stroma.

Midwifery students' conceptions of worst imaginable pain

- Background: The Visual Analogue Scale (VAS) is one of the most widely used pain assessment scales in clinical practice and research. However, the VAS is used less frequently in midwifery than in other clinical contexts. The issue of how people interpret the meaning of the VAS endpoints (i.e. no pain and worst imaginable pain) has been discussed. The aim of this study was to explore midwifery students' conceptions of 'worst imaginable pain'. Methods: A sample of 230 midwifery students at seven universities in Sweden responded to an open-ended question: 'What is the worst imaginable pain for you?' This open-ended question is a part of a larger study. Their responses underwent manifest content analysis. Results: Analysis of the midwifery students' responses to the open-ended question revealed five categories with 24 sub-categories. The categories were Overwhelming pain, Condition-related pain, Accidents, Inflicted pain and Psychological suffering. Conclusions: The midwifery students' conceptions of 'worst imaginable pain' are complex, elusive and diverse. © 2014 Australian College of Midwives.
