- Different types of progenitor and stem cells have been shown to provide neuroprotection in animal models of photoreceptor degeneration. The present study was conducted to investigate whether human neural progenitor cells (HNPCs) have neuroprotective properties on retinal explants models with calpain- and caspase-3-dependent photoreceptor cell death. In the first experiments, HNPCs in a feeder layer were co-cultured for 6 days either with postnatal rd1 mouse or normal rat retinas. Retinal histological sections were used to determine outer nuclear layer (ONL) thickness, and to detect the number of photoreceptors with labeling for calpain activity, cleaved caspase-3 and TUNEL The ONL thickness of co-cultured rat and rd1 retinas was found to be almost 10% and 40% thicker, respectively, compared to controls. Cell counts of calpain activity, cleaved caspase-3 and TUNEL labeled photoreceptors in both models revealed a 30-50% decrease when co-cultured with HNPCs. The results represent significant increases of photoreceptor survival in the co-cultured retinas. In the second experiments, for an identification of putative survival factors, or a combination of them, a growth factor profile was performed on conditioned medium. The relative levels of various growth factors were analyzed by densitometric measurements of growth factor array membranes. Following growth factors were identified as most potential survival factors: granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor (GMCSF), insulin-like growth factor 11 (IGF-II), neurotrophic factor 3 (NT-3), placental growth factor (PIGF), transforming growth factors (TGF-beta 1 and TGF-beta 2) and vascular endothelial growth factor (VEGF-D). HNPCs protect both against calpain- and caspase-3-dependent photoreceptor cell death in the rd1 mouse and against caspase-3-dependent photoreceptor cell death in normal rat retinas in vitro. The protective effect is possibly achieved by a variety of growth factors secreted from the HNPCs. (C) 2009 Elsevier Ltd. All rights reserved.

- Cancers have dysfunctional redox regulation resulting in reactive oxygen species production, damaging both DNA and free dNTPs. The MTH1 protein sanitizes oxidized dNTP pools to prevent incorporation of damaged bases during DNA replication. Although MTH1 is non-essential in normal cells, we show that cancer cells require MTH1 activity to avoid incorporation of oxidized dNTPs, resulting in DNA damage and cell death. We validate MTH1 as an anticancer target in vivo and describe small molecules TH287 and TH588 as first-in-class nudix hydrolase family inhibitors that potently and selectively engage and inhibit the MTH1 protein in cells. Protein co-crystal structures demonstrate that the inhibitors bindin the active site of MTH1. The inhibitors cause incorporation of oxidized dNTPs in cancer cells, leading to DNA damage, cytotoxicity and therapeutic responses in patient-derived mouse xenografts. This study exemplifies the non-oncogene addiction concept for anticancer treatment and validates MTH1 as being cancer phenotypic lethal.

- BACKGROUND:: Nurses' attitudes toward caring for dying persons need to be explored. The Frommelt Attitude Toward Care of the Dying (FATCOD) scale has not previously been used in Swedish language. OBJECTIVES:: The objectives of this study were to compare FATCOD scores among Swedish nurses and nursing students with those from other languages, to explore the existence of 2 subscales, and to evaluate influences of experiences on attitudes toward care of dying patients. METHODS:: A descriptive, cross-sectional, and predictive design was used. The FATCOD scores of Swedish nurses from hospice, oncology, surgery clinics, and palliative home care and nursing students were compared with published scores from the United States, Israel, and Japan. Descriptive statistics, t tests, and factor and regression analyses were used. RESULTS:: The sample consisted of 213 persons: 71 registered nurses, 42 enrolled nurses, and 100 nursing students. Swedish FATCOD mean scores did not differ from published means from the United States and Israel, but were significantly more positive than Japanese means. In line with Japanese studies, factor analyses yielded a 2-factor solution. Total FATCOD and subscales had low Cronbach α's. Hospice and palliative team nurses were more positive than oncology and surgery nurses to care for dying patients. CONCLUSIONS:: Although our results suggest that the Swedish FATCOD may comprise 2 distinct scales, the total scale may be the most adequate and applicable for use in Sweden. Professional experience was associated with nurses' attitudes toward caring for dying patients. IMPLICATION FOR PRACTICE:: Care culture might influence nurses' attitudes toward caring for dying patients; the benefits of education need to be explored.

Smart placement of a mediastinal drain in a neonate who requires a postoperative open sternum.

- Crowding of the mediastinum after complex cardiac repair procedures in neonates and young children is a frequent problem. To create space, the sternal wound is kept open, commonly with a plastic stent, for later closure. Despite this maneuver, space is still an issue, and appropriate placement of the mediastinal drain can become a challenge. In this article we describe a simple and effective way to eliminate the problem. Holes are made in the sternal stent, and the drain is pulled through these holes. The drain is elevated away from the heart surface and does not contribute to the crowding.

Existential Reflections among Nurses in Surgical Care

- Objectives: To gain a deeper understanding of surgical nurses’ experiences of existential issues in cancer care.Methods: Written critical incidents were used to collect nurses’ descriptions and reflections of critical care situations involving existential issues. Individual face-to-face interviews were conducted as follow-up using semi-structured questions which were analysed with hermeneutical analysis. Preliminary results: The analysis showed that nurses in surgical care experience caring from different positions. Nurses either focus on the patient as a whole in the caring process or nurses focus more on medical information in the caring process. When focusing on the patient as a whole existential issues are considered to be a natural part of the caring process and nurses’ personal experiences help to enable encounters with the patients. When focusing more on the medical information in the caring process there was a transfer of responsibility to others, mainly the physicians. Preliminary conclusions: This study highlights that existential issues are indeed part of surgical cancer care derived from existential care situations. Nurses’ focus in the caring process differs. Nurses express different positions in caring and not all acknowledge patients’ existential issues as part of nurses’ responsibility. When lacking common strategies in the organization nurses derive existential caring strategies from personal experiences.

- Forty-four patients with malignant diseases for which they received peripheral stem cell transplant therapy (PSCT) were retrospectively studied regarding local and systemic infection originating from around partially erupted third molars (PEMs). Twenty-two patients had one or more PEMs, while 22 patients had none. Data were retrieved from medical and dental records. Systemic and local signs of infection and treatment were assessed. We recorded the number of transplanted CD34(+) blood stem cells, days with white blood cell counts < 0.5 x 10(9) l(-1), days until engraftment, maximum level of C-reactive protein (CRP), days with fever, positive blood cultures, days taking antibiotics, days drinking < 0.5 l, days of total parenteral nutrition, days receiving intravenously administered analgesics, and number of admission days. No statistically significant difference was detected between patients with PEMs and those without PEMs regarding any of the studied parameters. Of patients with PEMs, 36% (8 of 22) developed local infections around PEMs during the PSCT period. The study indicates that PEMs pose no significant risk of causing systemic infection in patients receiving PSCT for malignant diseases but increase the risk of developing a local infection, justifying close supervision and early treatment in cases of local infection during PSCT treatment.
