Abstract
Neutrophils are known to contribute in many aspects of tumor progression and metastasis. The presence of neutrophils or neutrophil-derived mediators in the tumor microenvironment has been associated with poor prognosis in several types of solid tumors. However, the effects of classical cancer treatments such as radiation therapy on neutrophils are poorly understood. Furthermore, the cellular composition and distribution of immune cells in the tumor is of increasing interest in cancer research and new imaging technologies allow to perform more complex spatial analyses within tumor tissues. Therefore, we aim to offer novel insight into intra-tumoral formation of cellular neighborhoods and communities in murine breast cancer. To address this question, we performed image mass cytometry on tumors of the TS/A breast cancer tumor model, performed spatial neighborhood analyses of the tumor microenvironment and quantified neutrophil-extracellular trap degradation products in serum of the mice. We show that irradiation with 2 × 8 Gy significantly alters the cellular composition and spatial organization in the tumor, especially regarding neutrophils and other cells of the myeloid lineage. Locally applied radiotherapy further affects neutrophils in a systemic manner by decreasing the serum neutrophil extracellular trap concentrations which correlates positively with survival. In addition, the intercellular cohesion is maintained due to radiotherapy as shown by E-Cadherin expression. Radiotherapy, therefore, might affect the epithelial-mesenchymal plasticity in tumors and thus prevent metastasis. Our findings underscore the growing importance of the spatial organization of the tumor microenvironment, particularly with respect to radiotherapy, and provide insight into potential mechanisms by which radiotherapy affects epithelial-mesenchymal plasticity and tumor metastasis.

Abstract
BACKGROUND Following the publication of the European consensus statement on standards for essential colposcopy in 2020, the need for standards relating to more complex and challenging colposcopy practice was recognised. These standards relate to colposcopy undertaken in patients identified through cervical screening and tertiary referrals from colposcopists who undertake standard colposcopy only. This set of recommendations provides a review of the current literature and agreement on care for recognised complex cases. With good uptake of human papillomavirus (HPV) immunisation, we anticipate a marked reduction in cervical disease over the next decade. Still, the expert colposcopist will continue to be vital in managing complex cases, including previous cervical intraepithelial neoplasia (CIN)/complex screening histories and multi-zonal disease. AIMS To provide expert guidance on complex colposcopy cases through published evidence and expert consensus. MATERIAL & METHODS Members of the EFC and ESGO formed a working group to identify topics considered to be the remit of the expert rather than the standard colposcopy service. These were presented at the EFC satellite meeting, Helsinki 2021, for broader discussion and finalisation of the topics. RESULTS & DISCUSSION The agreed standards included colposcopy in pregnancy and post-menopause, investigation and management of glandular abnormalities, persistent high-risk HPV+ with normal/low-grade cytology, colposcopy management of type 3 transformation zones (TZ), high-grade cytology and normal colposcopy, colposcopy adjuncts, follow-up after treatment with CIN next to TZ margins and follow-up after treatment with CIN with persistent HPV+, and more. These standards are under review to create a final paper of consensus standards for dissemination to all EFC and ESGO members.

Abstract
Tumor recurrence is a major problem during the treatment of giant cell tumors of bone (GCTB). We recently identified tumor cell-specific cytotoxic effects of bioactive glasses (BGs) toward neoplastic stromal cells derived from GCTB tissue (GCTSCs) in vitro. Since these data indicated a promising role of BGs in the adjuvant treatment of GCTBs, we aimed to investigate the transferability of the in vitro data into the more complex in vivo situation in the current study. We first analyzed the cytotoxicity of three different BGs in vitro by WST-1 assay after co-cultivation with primary GCTSC cell lines. The effects of BGs on tumor engraftment and growth were analyzed by chicken chorioallantoic membrane (CAM) assays and subsequent quantification of tumor take rates and tumor volumes. In vitro, all tested BGs displayed a cytotoxic effect on GCTSCs that was dependent on BG composition, concentration, and particle size. Comparable effects could be observed within the in vivo environment resulting in reduced tumor take rates and tumor volumes in BG-treated samples. These data indicate a possible clinical application of BGs in the context of GCTB therapy, mediating a reduction of recurrence rates with the simultaneous promotion of bone regeneration.

Abstract
Background In this exploratory study, the impact of local irradiation on systemic changes in stress and immune parameters was investigated in eight patients treated with intensity-modulated radiation therapy (IMRT) or stereotactic ablative body radiotherapy (SABR) for prostate adenocarcinoma to gain deeper insights into how radiotherapy (RT) modulates the immune system. Patients and methods RT-qPCR, flow cytometry, metabolomics, and antibody arrays were used to monitor a panel of stress- and immune-related parameters before RT, after the first fraction (SABR) or the first week of treatment (IMRT), after the last fraction, and 3 weeks later in the blood of IMRT (N = 4) or SABR (N = 4) patients. Effect size analysis was used for comparison of results at different timepoints. Results Several parameters were found to be differentially modulated in IMRT and SABR patients: the expression of TGFB1, IL1B, and CCL3 genes; the expression of HLA-DR on circulating monocytes; the abundance and ratio of phosphatidylcholine and lysophosphatidylcholine metabolites in plasma. More immune modulators in plasma were modulated during IMRT than SABR, with only two common proteins, namely GDF-15 and Tim‑3. Conclusion Locally delivered RT induces systemic modulation of the immune system in prostate adenocarcinoma patients. IMRT and SABR appear to specifically affect distinct immune components.

Abstract
Soil nitrogen mineralisation (Nmin), the conversion of organic into inorganic N, is important for productivity and nutrient cycling. The balance between mineralisation and immobilisation (net Nmin) varies with soil properties and climate. However, because most global-scale assessments of net Nmin are laboratory-based, its regulation under field-conditions and implications for real-world soil functioning remain uncertain. Here, we explore the drivers of realised (field) and potential (laboratory) soil net Nmin across 30 grasslands worldwide. We find that realised Nmin is largely explained by temperature of the wettest quarter, microbial biomass, clay content and bulk density. Potential Nmin only weakly correlates with realised Nmin, but contributes to explain realised net Nmin when combined with soil and climatic variables. We provide novel insights of global realised soil net Nmin and show that potential soil net Nmin data available in the literature could be parameterised with soil and climate data to better predict realised Nmin.

Abstract
BACKGROUND Cochlea sparing can reduce late ototoxicity in head and neck cancer patients treated with cisplatin-based radiochemotherapy. In this situation, a mean cochlear dose (MCD) constraint of 10 Gy has been suggested by others based on the dose-effect relationship of clinical data. We aimed to investigate whether this is feasible for primary and postoperative radiochemotherapy in locoregionally advanced tumors without compromising target coverage. PATIENTS AND METHODS Ten patients treated with definitive and ten patients treated with adjuvant intensity-modulated radiotherapy (IMRT) and concurrent chemotherapy were investigated. The cochleae and a planning risk volume (PRV) with a 3 mm margin were newly delineated, whereas target volumes and other organs at risk were not changed. The initial plan was recalculated with a constraint of 10 Gy (MCD) on the low-risk side. The quality of the resulting plan was evaluated using the difference in the equivalent uniform dose (EUD). RESULTS A unilateral MCD of below 10 Gy could be achieved in every patient. The mean MCD was 6.8 Gy in the adjuvant cohort and 7.6 Gy in the definitive cohort, while the non-spared side showed a mean MCD of 18.7 and 30.3 Gy, respectively. The mean PRV doses were 7.8 and 8.4 Gy for the spared side and 18.5 and 29.8 Gy for the non-spared side, respectively. The mean EUD values of the initial and recalculated plans were identical. Target volume was not compromised. CONCLUSION Unilateral cochlea sparing with an MCD of less than 10 Gy is feasible without compromising the target volume or dose coverage in locoregionally advanced head and neck cancer patients treated with IMRT. A prospective evaluation of the clinical benefit of this approach as well as further investigation of the dose-response relationship for future treatment modification appears promising.

Abstract
BACKGROUND Endoplasmic reticulum (ER) stress plays a crucial role in cell death decisions in context of various diseases. Although it is known that ER stress occurs in livers subjected to hemorrhagic shock and reperfusion (HS/R), there is no understanding about the influence of the liver architecture on ER stress and the activation of the unfolded protein response (UPR). MATERIALS AND METHODS Mice were subjected to a pressure-controlled HS (30 ± 5 mmHg) for 90 min. Mice were sacrificed 2, 4, 6, 8, 10, 14, 18, and 24 h after shock induction. Plasma levels of inflammatory cytokines (IL-6, CXCL1, CXCL9, CXCL10, CCL2, CCL3) and transaminases were measured. Hematoxylin and eosin stains of paraffin-embedded liver tissue sections were evaluated for liver damage. Immunohistochemistry was used to analyze the hepatic topography of ER stress marker binding immunoglobulin protein and the activation of the three major pathways of the UPR. RESULTS Compared with sham-operated mice, HS/R led to profound liver damage and an elevation of inflammatory cytokines. We found time-dependent topographical changes of ER stress in the livers. Furthermore, the three major pathways of the UPR represented by protein kinase RNA-like ER kinase, activating transcription factor 6, and inositol-requiring enzyme 1 were activated in differing ways dependent on the zonation within the liver acinus. CONCLUSIONS These findings show that the liver architecture must be taken into account when investigating the role of ER stress and the UPR in ischemia-reperfusion injury after HS/R.

Abstract
Bison from Yellowstone National Park (YNP) have a unique genetic history that makes them a conservation priority for the species. Unfortunately, there is a high prevalence of the zoonotic disease brucellosis in the herd. Part of the management strategy for controlling the disease and herd size in YNP is an annual culling process. This culling may result in loss of valuable genetic material and, until now, has been a missed opportunity to recover and preserve those genetics. The goal of this project was to demonstrate the feasibility of producing healthy offspring from reproductive material collected during the nonbreeding season from bison postmortem and to determine effects of donor parameters, including sexual maturity and pregnancy status on IVF outcomes. Oocytes were collected from ovaries harvested from bison within 2 h of slaughter during winters of 2014 to 2017 for use in in vitro embryo production (IVP). Frozen-thawed semen from 7 YNP bulls collected via electroejaculation in vivo or from epididymal flushes postmortem was used for IVF. Embryos were produced using standard cattle IVP procedures. On Days 7, 7.5, and 8 of in vitro culture, embryos were assessed for developmental stage and quality, and Grade 1 and 2 embryos were vitrified on Cryotops® (Kitazato, Tokyo, Japan) in a two-step equilibration process. Embryos were then stored until the breeding season when they were warmed, cultured for 6 h, evaluated for survival, and transferred to healthy bison recipients. Data were analysed using a Student’s t-test. Age did not affect the mean number of oocytes collected from a mature female (n = 254) v. juvenile (n = 27; 24 ± 16 v. 24 ± 13), embryo cleavage rates (54 ± 24% v. 45 ± 24%), or the rate of blastocyst development (8 ± 12% v. 7 ± 8%, respectively). Pregnancy status did have a significant effect on the number of oocytes collected per female (pregnant 22 ± 15%, n = 258; nonpregnant 26 ± 20%, n = 82; P = 0.04) and the percent of oocytes that cleaved (pregnant 56 ± 23%, n = 189; nonpregnant 47 ± 24, n = 61; P = 0.005). No difference was detected in the percent of embryos that reached the blastocyst stage of development (pregnant 8 ± 10%, nonpregnant 8 ± 15%). In August 2016, 12 embryos were transferred singly or in pairs to 10 recipient bison synchronized using a standard synch protocol. Ten days following removal of the CIDR, embryos were transferred to recipient bison with a palpable corpus luteum. In spring of 2017, a healthy female calf was born to a recipient who had received 2 Grade-2 blastocysts as graded at the end of the 6-h incubation period. The genetic dam of the calf was a pregnant adult bison cow. This calf demonstrates that live offspring can be generated from oocytes collected from bison postmortem in the nonbreeding season. Although cleavage rates were higher with oocytes from pregnant bison, viable embryos were generated from nonpregnant adults and juvenile females, warranting continued collection of their oocytes and banking of resulting embryos. To our knowledge, this is the first bison calf produced by in vitro production using postmortem reproductive material.

Abstract
BACKGROUND AND PURPOSE Small animal irradiation systems were developed for preclinical evaluation of tumor therapy closely resembling the clinical situation. Mostly only clinical LINACs are available, so protocols for small animal partial body irradiation using a conventional clinical system are essential. This study defines a protocol for conformal brain tumor irradiations in mice. MATERIALS AND METHODS CT and MRI images were used to demarcate the target volume and organs at risk. Three 6 MV photon beams were planned for a total dose of 10 fractions of 1.8 Gy. The mouse position in a dedicated applicator was verified by an X‑ray patient positioning system before each irradiation. Dosimetric verifications (using ionization chambers and films) were performed. Irradiation-induced DNA damage was analyzed to verify the treatment effects on the cellular level. RESULTS The defined treatment protocol and the applied fractionation scheme were feasible. The in-house developed applicator was suitable for individual positioning at submillimeter accuracy of anesthetized mice during irradiation, altogether performed in less than 10 min. All mice tolerated the treatment well. Measured dose values perfectly matched the nominal values from treatment planning. Cellular response was restricted to the target volume. CONCLUSION Clinical LINAC-based irradiations of mice offer the potential to treat orthotopic tumors conformably. Especially with respect to lateral penumbra, dedicated small animal irradiation systems exceed the clinical LINAC solution.

Abstract
BACKGROUND Therapeutic hypothermia following hypoxic ischaemic encephalopathy in term infants was introduced into Switzerland in 2005. Initial documentation of perinatal and resuscitation details was poor and neuromonitoring insufficient. In 2011, a National Asphyxia and Cooling Register was introduced. AIMS To compare management of cooled infants before and after introduction of the register concerning documentation, neuromonitoring, cooling methods and evaluation of temperature variability between cooling methods. STUDY DESIGN Data of cooled infants before the register was in place (first time period: 2005-2010) and afterwards (second time period: 2011-2012) was collected with a case report form. RESULTS 150 infants were cooled during the first time period and 97 during the second time period. Most infants were cooled passively or passively with gel packs during both time periods (82% in 2005-2010 vs 70% in 2011-2012), however more infants were cooled actively during the second time period (18% versus 30%). Overall there was a significant reduction in temperature variability (p < 0.001) comparing the two time periods. A significantly higher proportion of temperature measurements within target temperature range (72% versus 77%, p < 0.001), fewer temperature measurements above (24% versus 7%, p < 0.001) and more temperatures below target range (4% versus 16%, p < 0.001) were recorded during the second time period. Neuromonitoring improved after introduction of the cooling register. CONCLUSION Management of infants with HIE improved since introducing the register. Temperature variability was reduced, more temperature measurements in the target range and fewer temperature measurements above target range were observed. Neuromonitoring has improved, however imaging should be performed more often.

Abstract
Benign painful and inflammatory diseases have been treated for decades with low/moderate doses of ionizing radiation (LD-X-irradiation). Tissue macrophages regulate initiation and resolution of inflammation by the secretion of cytokines and by acting as professional phagocytes. Having these pivotal functions, we were interested in how activated macrophages are modulated by LD-X-irradiation, also with regard to radiation protection issues and carcinogenesis. We set up an ex-vivo model in which lipopolysaccharide pre-activated peritoneal macrophages (pMΦ) of radiosensitive BALB/c mice, mimicking activated macrophages under inflammatory conditions, were exposed to X-irradiation from 0·01 Gy up to 2 Gy. Afterwards, the viability of the pMΦ, their transmigration and chemotaxis, the phagocytic behaviour, the secretion of inflammatory cytokines and underlying signalling pathways were determined. Exposure of pMΦ up to a single dose of 2 Gy did not influence their viability and phagocytic function, an important fact regarding radiation protection. However, significantly reduced migration, but increased chemotaxis of pMΦ after exposure to 0·1 or 0·5 Gy, was detected. Both might relate to the resolution of inflammation. Cytokine analyses revealed that, in particular, the moderate dose of 0·5 Gy applied in low-dose radiotherapy for inflammatory diseases results in an anti-inflammatory cytokine microenvironment of pMΦ, as the secretion of the proinflammatory cytokine interleukin (IL)-1β was reduced and that of the anti-inflammatory cytokine transforming growth factor (TGF)-β increased. Further, the reduced secretion of IL-1β correlated with reduced nuclear translocation of nuclear factor (NF)-κB p65, starting at exposure of pMΦ to 0·5 Gy of X-irradiation. We conclude that inflammation is modulated by LD-X-irradiation via changing the inflammatory phenotype of macrophages.

Abstract
QUESTION Is there an association between the presence of nucleated red blood cells (NRBCs) in the peripheral blood and outcomes in critically ill children? METHODS Prospective observational study conducted in 2008 (January to December) in a multidisciplinary paediatric intensive care unit (PICU) of a tertiary children's hospital. We provide univariate analysis, stratified by age group (neonates and children >28 days of age), and multiple logistic regression, comparing clinically important outcomes (death, ventilation, renal replacement therapy, inotropic support) with haematological (NRBC, haemoglobin, platelets, leucocytes), illness severity (expected mortality [paediatric index of mortality, PIM2]), demographic (age, sex) and diagnostic parameters and length of stay. Haematological parameters correspond to the first 24 hours of PICU admission. RESULTS Out of 670 patients, 195 (29.1%) were NRBC positive and 475 (70.9%) were NRBC negative. In the neonatal age group (n = 232), patients who died, were ventilated or received inotropic support had significantly more NRBCs than patients without these conditions (p = 0.032, 0.038 and 0.029, respectively). In the child age group (n = 438), only renal replacement therapy was significantly associated with NRBC (p <0.001). High PIM score (p <0.001) and longer length of stay (p <0.001) were independently associated with bad outcomes (composite endpoint: mortality and/or ventilation and/or renal replacement therapy and/or inotropic support); NRBC positivity was not an independent predictor of bad outcome (odds ratio 1.44, 95% confidence interval 0.62‒3.41). CONCLUSIONS NRBCs are not an independent risk factor for bad outcomes in paediatric intensive care. However, NRBCs may have some prognostic value in the first month of life. In children >1 month of age, the association between NRBC and outcome is much less pronounced.

Abstract
BACKGROUND AND PURPOSE To evaluate the long-term efficacy of pain reduction by two dose-fractionation schedules for radiotherapy of painful shoulder syndrome. PATIENTS AND METHODS Between February 2006 and February 2010, 312 evaluable patients were recruited for this prospective trial. All patients received low-dose orthovoltage radiotherapy. One course consisted of 6 fractions in 3 weeks. In the case of insufficient pain remission after 6 weeks, a second course was administered. Patients were randomly assigned to one of two groups to receive single doses of either 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before radiotherapy, as well as immediately after (early response), 6 weeks after (delayed response) and approximately 3 years after (long-term response) completion of radiotherapy using a questionnaire-based visual analogue scale (VAS) and a comprehensive pain score (CPS). RESULTS Median follow-up was 35 months (range 11-57). The overall early, delayed and long-term response rates for all patients were 83, 85 and 82 %, respectively. The mean VAS scores before treatment and those for early, delayed and long-term response in the 0.5- and 1.0-Gy groups were 56.8 ± 23.7 and 53.2 ± 21.8 (p = 0.16); 38.2 ± 36.1 and 34.0 ± 24.5 (p = 0.19); 33.0 ± 27.2 and 23.7 ± 22.7 (p = 0.04) and 27.9 ± 25.8 and 32.1 ± 26.9 (p = 0.25), respectively. The mean CPS values before treatment and those for early, delayed and long-term response were 9.7 ± 3.0 and 9.5 ± 2.7 (p = 0.31); 6.1 ± 3.6 and 5.4 ± 3.6 (p = 0.10); 5.3 ± 3.7 and 4.1 ± 3.7 (p = 0.05) and 4.0 ± 3.9 and 5.3 ± 4.4 (p = 0.05), respectively. No significant differences in the quality of the long-term response were found between the 0.5- and 1.0-Gy arms (p = 0.28). CONCLUSION Radiotherapy is an effective treatment for the management of benign painful shoulder syndrome. For radiation protection reasons, the dose for a radiotherapy series should not exceed 3.0 Gy.

Abstract
A split plot experiment with 72 male pigs weighing 52.9 ± 0.39 kg (mean ± SEM) was conducted to examine AA partitioning and body protein deposition (PD) in response to increasing dietary sulfur amino acids (SAA) with or without immune system (IS) activation. The main plot was with and without IS activation, and 4 diets containing different amounts of standardized ileal digestible (SID) SAA (SAA to Lys ratios of 0.45, 0.55, 0.65 and 0.75) were the subplots. Activation of IS was achieved by intramuscular injection of Escherichia coli lipopolysaccharides (LPS; serotype 055:B5, Sigma; 30 μg/kg BW) every Monday and Thursday, with control pigs injected with sterile saline. Maximum body PD, measured by dual-energy X-ray absorptiometry (DXA), and minimum plasma urea content were achieved at SID SAA:Lys ratio of 0.55 in saline-injected pigs but were achieved at a SID SAA:Lys ratio of 0.75 in IS-activated pigs. Immune system activation increased rectal temperature (P < 0.05), plasma haptoglobin (1.1 vs. 2.0 mg/mL; P < 0.001), and the proportion of neutrophils (0.39 vs. 0.42; P < 0.05) and decreased serum albumin content (38.4 vs. 36.8 g/L; P < 0.01). Increasing dietary SAA had no effects on these variables. Immune system-activated pigs had lower levels of homocysteine (Hcy; P < 0.001) and a lower Ser content (P < 0.05). Results showed that increasing dietary SAA as DL-methionine in growing and/or finishing pigs altered plasma AA contents, and that use efficiency of the AA was improved when greater levels of SAA were supplemented in IS-activated pigs.

Abstract
PURPOSE The aim of this work was to compare the efficacy of two different dose fractionation schedules for radiotherapy of patients with calcaneodynia. PATIENTS AND METHODS Between February 2006 and April 2010, 457 consecutive evaluable patients were recruited for this prospective randomized trial. All patients received radiotherapy using the orthovoltage technique. One radiotherapy series consisted of 6 single fractions/3 weeks. In case of insufficient remission of pain after 6 weeks a second radiation series was performed. Patients were randomly assigned to receive either single doses of 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before, immediately after, and 6 weeks after radiotherapy using a visual analogue scale (VAS) and a comprehensive pain score (CPS). RESULTS The overall response rate for all patients was 87 % directly after and 88 % 6 weeks after radiotherapy. The mean VAS values before, immediately after, and 6 weeks after treatment for the 0.5 and 1.0 Gy groups were 65.5 ± 22.1 and 64.0 ± 20.5 (p = 0.188), 34.8 ± 24.7 and 39.0 ± 26.3 (p = 0.122), and 25.1 ± 26.8 and 28.9 ± 26.8 (p = 0.156), respectively. The mean CPS before, immediately after, and 6 weeks after treatment was 10.1 ± 2.7 and 10.0 ± 3.0 (p = 0.783), 5.6 ± 3.7 and 6.0 ± 3.9 (p = 0.336), 4.0 ± 4.1 and 4.3 ± 3.6 (p = 0.257), respectively. No statistically significant differences between the two single dose trial arms for early (p = 0.216) and delayed response (p = 0.080) were found. CONCLUSION Radiotherapy is an effective treatment option for the management of calcaneodynia. For radiation protection reasons, the dose for a radiotherapy series is recommended not to exceed 3-6 Gy.

Abstract
Fungi were isolated from fine granitic sediments, which were collected at 15 sampling points within a 20 m × 40 m area in front of the Damma glacier in the central Swiss Alps. From the 45 fungal isolates grown on nutrient-rich agar media at 4 °C, 24 isolates were selected for partial sequencing and identification based on the small subunit ribosomal DNA. Sequencing data revealed that the isolated fungi represented three fungal phyla and 15 species. The weathering potential of 10 of the 15 fungal species was tested with dissolution experiments using powdered granite material (<63 μm). The results showed that the zygomyceteous species Mucor hiemalis, Umbelopsis isabellina and Mortierella alpina dissolved the granite powder most efficiently due to the release of a variety of organic acids, mainly citrate, malate and oxalate. In particular, the high concentrations of Ca, Fe, Mg and Mn in the solutions clustered well with the high amounts of exuded citrate. This is the first report on fungi that were isolated from a non-vegetated glacier forefield in which the fungi's capabilities to dissolve granite minerals were examined.

Abstract
BACKGROUND With more liberal visiting hours in paediatric intensive care practice, parents' presence at the bedside has increased. Parents may thus become involved in critical incidents as contributors or detectors of critical incidents or they may be affected by critical incidents. METHODS Voluntary, anonymous, non-punitive critical incident reporting system. Parents' involvement in critical incidents has been evaluated retrospectively (January 2002 to August 2007). The reports were analysed regarding involvement of parents, age of child, unit (paediatric intensive care or intermediate neonatal nursery), critical incident severity, critical incident category, actual or potential harm to patient and/or parent (minor, moderate, major), delay between the critical incident and its detection, and implemented system changes. RESULTS Overall, 2494 critical incidents have been reported. There were 101 critical incidents with parental involvement: parents as contributors to critical incident (18; 0.7%), parents discovering a critical incident (11; 0.4%), parents affected by critical incident (72; 2.9%). The most vulnerable categories regarding contribution and detection were drugs, line/drain disconnection, trauma and hygiene. Ten critical incidents precipitated by parents were of moderate severity and seven of potential major severity (six line/drain disconnections). The majority of the events (six) detected by parents were of potential moderate severity and four were of major severity. CONCLUSION Because of their presence at the bedside, parents in the paediatric intensive care unit are inevitably involved in safety issues. It is not the parents' duty to guarantee the safety for their children, but parents should be encouraged to report anything that worries them. Only an established safety culture allows parents to articulate their concerns.

Abstract
Most of the classical therapies for solid tumors have limitations in achieving long-lasting anti-tumor responses. Therefore, treatment of cancer requires additional and multimodal therapeutic strategies. One option is based on the vaccination of cancer patients with autologous inactivated intact tumor cells. The master requirements of cell-based therapeutic tumor vaccines are the: (a) complete inactivation of the tumor cells; (b) preservation of their immunogenicity; and (c) need to remain in accordance with statutory provisions. Physical treatments like freeze-thawing and chemotherapeutics are currently used to inactivate tumor cells for vaccination purposes, but these techniques have methodological, therapeutic, or legal restrictions. For this reason, we have proposed the use of a high hydrostatic pressure (HHP) treatment (p >or= 100 MPa) as an alternative method for the inactivation of tumor cells. HHP is a technique that has been known for more than 100 years to successfully inactivate micro-organisms and to alter biomolecules. In the studies here, we show that the treatment of MCF7, B16-F10, and CT26 tumor cells with HHP >or= 300 MPa results in mainly necrotic tumor cell death forms displaying degraded DNA. Only CT26 cells yielded a notable amount of apoptotic cells after the application of HHP. All tumor cells treated with >or= 200 MPa lost their ability to form colonies in vitro. Furthermore, the pressure-inactivated cells retained their immunogenicity, as tested in a xenogeneic as well as syngeneic mouse models. We conclude that the complete tumor cell inactivation, the degradation of the cell's nuclei, and the retention of the immunogeneic potential of these dead tumor cells induced by HHP favor the use of this technique as a powerful and low-cost technique for the inactivation of tumor cells to be used as a vaccine.

Abstract
Hyperthermia (HT)--heating the tumor in the range of 40.0- 44.0 °C--combined with radiation (RT) and/or chemotherapy (CT) is a well proven treatment for malignant tumors. The improvement of the techniques for monitoring and adapting of the desired temperatures even in deep seated tumors has led to a renaissance of, now quality-controlled, HT in multimodal tumor therapy approaches. Randomized clinical trials have shown improved disease-free survival and local tumor control without an increase in toxicity for the combined treatment. In this review, we will focus on biological rationales of HT comprising direct cytotoxicity, systemic effects, chemosensitization, radiosensitization, and immune modulation. The latter is a prerequisite for the control of recurrent tumors and micrometastases. Immunogenic tumor cell death forms induced by HT will be introduced. Modulations of the cytotoxic properties of chemotherapeutic agents by HT as well as synergistic effects of HT with RT will be presented in the context of the main aims of anti-tumor therapy. Furthermore, modern techniques for thermal mapping like magnet resonance imaging will be outlined. The effectiveness of HT will be demonstrated by reviewing recent clinical trials applying HT in addition to CT and/or RT. We conclude that hyperthermia is a very potent radio- as well as chemosensitizer, which fosters the induction of immunogenic dead tumor cells leading to local and in special cases also to systemic tumor control.

Abstract
Published chronic toxicity data for Hg(II) added to soils were assembled and evaluated to produce a data set comprising 52 chronic end-points, five each for plants and invertebrates and 42 for microbes. With end-points expressed in terms of added soil Hg(II) contents, Critical Limits were derived from the 5th percentiles of species sensitivity distributions, values of 0.13 microg(g soil)(-1) and 3.3 microg(g soil organic matter)(-1) being obtained. The latter value exceeds the currently recommended Critical Limit, used to determine Hg(II) Critical Loads in Europe, of 0.5 microg(g soil organic matter)(-1). We also applied the WHAM/Model VI chemical speciation model to estimate concentrations of Hg(2+) in soil solution, and derived an approximate Critical Limit Function (CLF) that includes pH; log [Hg(2+)](crit)=-2.15 pH -17.10. Because they take soil properties into account, the soil organic matter-based limit and the CLF provide the best assessment of toxic threat for different soils. For differing representative soils, each predicts a range of up to 100-fold in the dry weight-based content of mercury that corresponds to the Critical Limit.

Abstract
Low-dose radiation (single doses from 0.3 to 1.0 Gy) in clinical practice is mostly used to treat patients with several inflammatory diseases and painful degenerative disorders. Low-dose radiation is known to exert anti-inflammatory effects. However, the molecular and cellular mechanism are not fully analysed and most of the observed effects are based on empirical studies. We investigated the effects of low-dose radiation on the activation-induced cell death of polymorph nuclear granulocytes (PMN). A biphasic appearance of cell death in irradiated PMN was observed, displaying a relative maximum at 0.3 Gy and minimum at 0.5 Gy, respectively. This biphasic course of cell death was coincident with the protein level of total cellular Akt. We conclude that low-dose radiation exerts immunomodulatory effects on PMN contributing to the observed anti-inflammatory effects in clinical applications.

Abstract
OBJECTIVES Currently, evidence-based guidelines concerning the use of oral contraceptives (OCs) containing either 20 or 30 microg ethinyloestradiol (EE) and the same progestogen, are lacking. We wanted to identify whether Swiss gynaecologists and general practitioners (GPs) have specific criteria on which they base their prescribing habit. METHODS Two questionnaires were submitted to 158 physicians. The first one contained a list of possible criteria relevant for decision making and a description of specific clinical situations. The second one concerned actual patients who received either a 20 microg (Yasminelle) or a 30 microg (Yasmin) OC containing the same progestogen drospirenone. RESULTS The most relevant criteria for decision making (in hierarchical order) were family history of venous thromboembolic disease (VTE), headache, smoking, age beyond 35, stability of the menstrual cycle, breast tenderness, body mass index, irregular bleeding and acne. The 20 microg dosage was preferred for women older than 35, those smoking more than 15 cigarettes per day, those with a family history of VTE, and those complaining of breast tenderness or headache. The 30 microg dosage was preferred for patients with a history of irregular bleeding, a family history of osteoporosis, expected poor compliance and acne. CONCLUSION Swiss gynaecologists and GPs do not preferentially prescribe the lowest possible dosage of EE. They use indirect markers they consider relevant for differential prescribing. For some markers, there is inconsistency, indicating that preferences for 20 microg and 30 microg preparations may be influenced by other factors.
