Statistical analysis of arthroplasty register data.
Abstract Data from arthroplasty registers are often analyzed using survival methods. Several methodological problems exist, for example relating to competing events, non-random censoring, non-proportional hazards and dependent observations. League tables and ranking of specific survival results leds to further methodological difficulties. Most of these problems are, however, well known and a numbe
Current status on plasma biomarkers for acute mesenteric ischemia.
Clinical diagnosis of acute mesenteric ischemia is difficult. The aim of this review is to provide current status on the search for an accurate plasma biomarker for acute mesenteric ischemia. A search using the medical subject heading terms marker and mesenteric ischemia or intestinal ischemia or superior mesenteric artery occlusion or mesenteric venous thrombosis in the Medline and Embase databas
Is it a policy crisis or it is a health crisis? The Egyptian context--analysis of the Egyptian health policy for the H1N1 flu pandemic control.
A new influenza virus that was first detected in people in April 2009, was initially referred to colloquially as "swine flu", since it contained genes from swine, avian and human influenza viruses. It can, however, not be transmitted by eating pork or dealing with pigs. In Egypt, several hundred thousand pigs were killed in May, in spite of advice from global health authorities that such an action
Subjective stress reactivity in psoriasis - a cross sectional study of associated psychological traits.
Stress or psychological distress is often described as a causative or maintaining factor in psoriasis. Psychological traits may influence the appraisal, interpretation and coping ability regarding stressful situations. Detailed investigations of psychological traits in relation to stress reactivity in psoriasis are rare. The aim of this study was to examine whether patients with psoriasis who repo
Aspects on diagrammatic expansion for models related to a homogeneous electron gas
n a previous paper (see abstr. A76748 of 1974) the expansion of the irreducible self-energy of an electron gas was studied and found to give unreliable results for the satellites of the one-electron spectra function. This was due to the incorrect analytic properties of the corresponding green function. These results are confirmed and extended by studying a simple model (s-model) which allows the n

Radiative properties of EuII and EuIII obtained from lifetime and branching ratio measurements
Radiative lifetimes of nine levels in Eu II (4f(7)6p, 4f(6)5d6s and 4f(6)5d(2)) and Eu III (4f(6)5d) have been measured using time-resolved laser-induced fluorescence spectroscopy on a laser-produced europium plasma. Oscillator strengths for a number of Eu II lines have been derived by combining the lifetimes with branching ratios measured in the emission spectrum of a hollow-cathode lamp.

Scenario trees for inflow modelling in stochastic optimisation for energy planning
The Nordic countries Norway, Sweden, Finland and Denmark have formed a deregulated power market. Electricity bought and sold on this market is dominated by hydro power. However, hydro power generation is restricted by the amount of water in reservoirs. The inflow to these reservoirs shows a yearly cycle and seasonal planning of the production is necessary. Seasonal planning for a fictive power pr

Bariatric Surgery Provides a "Bridge to Transplant" for Morbidly Obese Patients with Advanced Heart Failure and May Obviate the Need for Transplantation.
In patients with advanced heart failure, morbid obesity is a relative contraindication to heart transplantation due to higher morbidity and mortality in these patients.

Symbionts as major modulators of insect health: lactic Acid bacteria and honeybees.
Lactic acid bacteria (LAB) are well recognized beneficial host-associated members of the microbiota of humans and animals. Yet LAB-associations of invertebrates have been poorly characterized and their functions remain obscure. Here we show that honeybees possess an abundant, diverse and ancient LAB microbiota in their honey crop with beneficial effects for bee health, defending them against micro

Elevated Serum Chemokine CXC Ligand 5 Levels Are Associated with Hypercholesterolemia But Not a Worsening of Insulin Resistance in Chinese People.
Objective: Recent study showed high chemokine CXC ligand 5 (CXCL5) is thought to be associated with insulin resistance in humans. However, evidence from large-scale populations about the relationship between serum CXCL5 level and metabolic phenotypes is scarce. Here we sought to evaluate serum CXCL5 distribution and its association with metabolic phenotypes among middle-aged and older Chinese. Res

Enolase of Streptococcus pneumoniae Binds Human Complement Inhibitor C4b-Binding Protein and Contributes to Complement Evasion.
Streptococcus pneumoniae (pneumococcus) is a pathogen that causes severe local and life-threatening invasive diseases, which are associated with high mortality rates. Pneumococci have evolved several strategies to evade the host immune system, including complement to disseminate and to survive in various host niches. Thus, pneumococci bind complement inhibitors such as C4b-binding protein (C4BP) a
Prior Adjuvant Tamoxifen Treatment in Breast Cancer Is Linked to Increased AIB1 and HER2 Expression in Metachronous Contralateral Breast Cancer.
The estrogen receptor coactivator Amplified in Breast Cancer 1 (AIB1) has been associated with an improved response to adjuvant tamoxifen in breast cancer, but also with endocrine treatment resistance. We hereby use metachronous contralateral breast cancer (CBC) developed despite prior adjuvant tamoxifen for the first tumor as an "in vivo"-model for tamoxifen resistance. AIB1-expression in the pre
