Abstract
The number of agile patients in the 10th decade with a strong need for postoperative mobility will increase in the following decades. The present prospective study sought to prove if very old patients with hip-related fractures are disadvantaged according to incidence of complications, length of ICU and in-hospital stay, and in-hospital mortality. We included 402 patients, age 60 years and older, with hip related fractures. Operative treatment consisted of osteosynthesis or endoprothesis. ASA score, body mass index, Charlson Comorbidity Index, Barthel Index and Mini-Mental-Status were documented. We noted length of in-hospital stay and ICU stay as well as readmission to ICU and complications, including their dispersal according to Clavien-Dindo Classification. After univariate analysis, a multivariate analysis was performed. The examined cohorts were 85 patients aged 60-74 years, 253 75-90 years old and 64 >90 year old patients. In-hospital periods (13-14 days) mean stay on ICU (2 days) and frequency of readmission on ICU did not significantly differ statistically. Most complications were grade II, with comparable frequency and modality, displaying no significant difference throughout age-related groups (p=0.461). In-hospital mortality showing significance (p=0.014) only between 75-89 (4.4%) and >90-year-old (12.5%) cohort. Nevertheless, according to multivariate analysis, including the common risk factors, increased age was not an independent risk factor for dying (p=0.132). Patients at an advanced age with hip-related fractures showed neither a prolonged in-hospital nor ICU stay. There was no significant relation of advanced age to number and type of complications.

Abstract
Psoriasis vulgaris is a common and chronic inflammatory skin disease which has the potential to significantly reduce the quality of life in severely affected patients. The incidence of psoriasis in Western industrialized countries ranges from 1.5 to 2%. Despite the large variety of treatment options available, patient surveys have revealed insufficient satisfaction with the efficacy of available treatments and a high rate of medication non-compliance. To optimize the treatment of psoriasis in Germany, the Deutsche Dermatologische Gesellschaft and the Berufsverband Deutscher Dermatologen (BVDD) have initiated a project to develop evidence-based guidelines for the management of psoriasis. The guidelines focus on induction therapy in cases of mild, moderate, and severe plaque-type psoriasis in adults. The short version of the guidelines reported here consist of a series of therapeutic recommendations that are based on a systematic literature search and subsequent discussion with experts in the field; they have been approved by a team of dermatology experts. In addition to the therapeutic recommendations provided in this short version, the full version of the guidelines includes information on contraindications, adverse events, drug interactions, practicality, and costs as well as detailed information on how best to apply the treatments described (for full version, please see Nast et al., JDDG, Suppl 2:S1-S126, 2006; or http://www.psoriasis-leitlinie.de ).

Abstract
BACKGROUND Chronic infection with Helicobacter pylori is related to the pathogenesis of the noncardia carcinoma of the stomach. In this study we investigated the mechanisms of H. pylori-induced apoptosis in T lymphocytes, which could explain a mechanism of immune evasion facilitating chronic inflammation of the mucosa and gastric carcinogenesis. MATERIALS AND METHODS The supernatant of H. pylori culture was used to study the mechanism of apoptosis induction in human leukaemia T cell lines Jurkat and CEM and in primary T cells. The cytotoxin associated gene A (CagA) and vacuolating cytotoxin A (Vac A) positive bacterial strain H. pylori 60190 (CagA(+), VacA(+)) and as a control the less toxic H. pylori strain Tx30a (CagA(-), VacA(-)) were used to produce the supernatant. Cell death was determined by DNA fragmentation and protein expression by Western blot. RESULTS H. pylori 60190-induced apoptosis was neither blocked by inhibition of the death ligands TRAIL (TNF-related apoptosis-inducing ligand), CD95L/FasL and TNF-alpha (tumour necrosis factor-a) in wild type Jurkat cells nor in FADD(def) (Fas-associated death domain protein) and caspase-8(def) subclones of the Jurkat cell line. Yet, the pancaspase inhibitor zVAD-fmk could inhibit up to 90% of H. pylori-induced apoptosis. Stable transfection of Jurkat wild type cells with Bcl-x(L and) Bcl-2 resulted in marked reduction of H. pylori-induced apoptosis, showing that the mitochondrial pathway is the key regulator. This is supported by the finding that surviving primary human lymphocytes upregulate Bcl-2 when exposed to H. pylori supernatant. CONCLUSIONS H. pylori-induced apoptosis of T cells is mediated by the mitochondrial pathway and could create a local environment that facilitates life-long infection by immune evasion.

Abstract
Healthcare institutions continue to face challenges in providing safe patient care in increasingly complex organisational and regulatory environments while striving to maintain financial viability. The clinical microsystem provides a conceptual and practical framework for approaching organisational learning and delivery of care. Tensions exist between the conceptual theory and the daily practical applications of providing safe and effective care within healthcare systems. Healthcare organisations are often complex, disorganised, and opaque systems to their users and their patients. This disorganisation may lead to patient discomfort and harm as well as much waste. Healthcare organisations are in some sense conglomerates of smaller systems, not coherent monolithic organisations. The microsystem unit allows organisational leaders to embed quality and safety into a microsystem's developmental journey. Leaders can set the stage for making safety a priority for the organisation while allowing individual microsystems to create innovative strategies for improvement.

Abstract
Abstract
Somatic hypermutation (SHM) targets primarily the immunoglobulin variable region (IgV) genes in germinal center (GC) B cells, thereby allowing antibody affinity maturation. A malfunction of SHM, termed aberrant somatic hypermutation (ASHM), was found in about 50% of diffuse large B-cell lymphomas (DLBCLs), leading to mutations in the 5′ sequences of multiple genes, including oncogenes. Although the SHM mechanism is largely unknown, it was shown to require the activation-induced cytidine deaminase (AID) gene. AID mRNA is expressed in GC B cells and GC-derived lymphomas, but the pattern of expression of the AID protein is not known. Using 2 specific antibodies, here we show that the AID protein can be detected in GC centroblasts and their transformed counterpart (Burkitt lymphoma) but not in pre-GC B cells and post-GC neoplasms, including B-cell chronic lymphocytic leukemia and multiple myeloma. DLBCLs displayed variable levels of AID expression, which did not correlate with IgV ongoing hypermutation, ASHM, or disease subtype. Finally, both in normal and malignant B cells the AID protein appeared predominantly localized in the cytoplasm. These results indicate that the AID protein is specifically expressed in normal and transformed GC B cells; nonetheless, its predominantly cytoplasmic localization suggests that additional mechanisms may regulate its function and may be altered during lymphomagenesis.

Abstract
Abstract. Breast muscles were removed from turkeys soon after slaughter. The meat quality was judged to be normal with little or no evidence of the pale, soft, exudative (PSE) condition. Fluid losses the day after slaughter were 0.50 SD 0.35 %. The most reliable predictor of fluid losses was resistance: r = –0.37 at 120 kHz, –0.30 at 1 Hz and –0.34 at 10 kHz (P < 0.001, n = 156). Between 1 and 4 days post-mortem, the mean drip loss from slices of turkey meat in a cooler was 4.31 SD 1.91%. Resistance was correlated with cooler drip loss: r = –0.61 at 120 Hz, –0.51 at 1 kHz and –0.62 at 10 kHz (P < 0.001, n = 45).

Abstract
Background. Transplant teams evaluate potential organ and tissue donors to exclude donation of tissues at risk for disease transmission. Standards dictate that serological tests be performed on every donor to assess the presence of transmissible diseases including: Human Immunodeficiency Virus 1 & 2, Human T Lymphotropic Virus 1 & 2, Hepatitis C, Hepatitis B surface Antigen, Hepatitis B core Antibody and Syphilis. A limitation of serological testing is the risk of false negative results due to the dilution of the serum. Hemodilution results from the transfusion of fluids (blood products, colloids and/or crystalloid). Confidence in the accuracy and sensitivity of donor serology testing is of utmost importance to ensure the provision of safe organs and tissues for transplantation.Methods. In order to determine the preferred and validated methodology for determining hemodilution, if any; and to determine the level of hemodilution that jeopardizes serologic test results, we reviewed the literature and current testing practices. Tissue banks throughout Canada as well as accrediting bodies were contacted regarding the hemodilution algorithm they utilize.Results. In the absence of a pretransfusion sample, hemodilution calculations are the prevalent methodology for assessing sensitivity of serology testing. A literature search and personal communications provided no documentation on the validation of any hemodilution algorithm or evidence that 50% hemodilution is an acceptable level for accurate serology testing.Conclusion. A validation of hemodilution algorithms and the acceptable or unacceptable rate of hemodilution is required. The utilization of a validated algorithm should be mandated in standards to ensure continuity of practice by all transplantation centres. If validation cannot be obtained, alternative methodologies for serology testing should be investigated.
