Characterization of fracture in topology-optimized bioinspired networks.

Designing strong and robust bioinspired structures requires an understanding of how function arises from the architecture and geometry of materials found in nature. We draw from trabecular bone, a lightweight bone tissue that exhibits a complex, anisotropic microarchitecture, to generate networked structures using multiobjective topology optimization. Starting from an identical volume, we generate multiple different models by varying the objective weights for compliance, surface area, and stability.

Bilirubin, urobilinogen, pancreas elastase and bile acid in drain fluid. The GBUP-study: Analysis of biomarkers for a colorectal anastomotic leakage.

Purpose: A colorectal anastomotic leakage (CAL) is a major complication after colorectal surgery and leads to high rates of morbidity and prolonged hospital stay. The study aims to evaluate the benefit of using bilirubin, urobilinogen, pancreas elastase and bile acid in the drain fluid (DF) as a predictive marker for the CAL.

Methods: From June 2015 to October 2017 100 patients, who underwent left hemicolectomy (LH), sigma resection (SR), high anterior resection (HAR), low anterior resection (LAR) or reversal of Hartmann's Procedure (ROHP) were included in this monocentric non-randomized prospective clinical trial.

Differences in serum zinc levels in acutely ill and remitted adolescents and young adults with bulimia nervosa in comparison with healthy controls - a cross-sectional pilot study.

Background: Research has implicated that changes in zinc (Zn) metabolism may be associated with the biological underpinnings of eating disorders, in particular anorexia nervosa. However, to date research on the role of Zn in patients with bulimia nervosa (BN) is scarce.

Objective: We aimed to explore serum Zn concentrations in young patients with BN, with a focus on the stage of the disorder, comparing acutely ill and recovered patients with BN with healthy controls.

CD74-Downregulation of Placental Macrophage-Trophoblastic Interactions in Preeclampsia.

Rationale: We hypothesized that cluster of differentiation 74 (CD74) downregulation on placental macrophages, leading to altered macrophage-trophoblast interaction, is involved in preeclampsia.

Objective: Preeclamptic pregnancies feature hypertension, proteinuria, and placental anomalies. Feto-placental macrophages regulate villous trophoblast differentiation during placental development.

Age-Dependent D-dimer Cut-off to Avoid Unnecessary CT-Exams for Ruling-out Pulmonary Embolism.

Purpose: To evaluate the effect of an age-dependent D-Dimer cut-off in patients who underwent a computed tomography pulmonary angiogram (CTPA) for suspected pulmonary embolism (PE) Material and Methods: Retrospective application of an age-dependent D-dimer cut-off (age/100 in patients aged over 50) in 530 consecutive patients, both in- and outpatients, aged over 18, who underwent CTPA for suspected PE according to the guidelines.

Results: The application of an age-dependent D-dimer cut-off showed a now negative test-result in 17 of 530 patients (3.2%).

Does age affect the relationship between control at work and sleep disturbance for shift workers?

Among miners, shift work, aging and lack of control at work may be factors leading to increased sleep problems. Such risk factors may also operate in interaction, resulting in an even increased harm for sleep disruption. The present study aims at evaluating these relationships drawing on a sample of Australian mine and energy workers and their partners.

High dose infusion of activated protein C (rhAPC) fails to improve neuronal damage and cognitive deficit after global cerebral ischemia in rats.

Purpose: Recent studies demonstrated anticoagulatory, antiinflammatory, antiapoptotic, and neuroprotective properties of activated protein C (APC) in rodent models of acute neurodegenerative diseases, suggesting APC as promising broad acting therapeutic agent. Unfortunately, continuous infusion of recombinant human APC (rhAPC) failed to improve brain damage following cardiac arrest in rats. The present study was designed to investigate the neuroprotective effect after global cerebral ischemia (GI) with an optimized infusion protocol.

Defining a reference population to determine the 99th percentile of a contemporary sensitive cardiac troponin I assay.

Background: Diagnosis of acute myocardial infarction (AMI) according to the universal definition is based on ischemic symptoms, imaging findings and elevated myocardial necrosis markers, preferably cardiac troponin I/T with diagnostic threshold representing the 99th percentile of a reference population. It is not clearly defined if this should be an unselected population-based or a healthy cohort with respect to cardiac diseases. Aim of the current study was to describe the distribution of troponin I using a sensitive assay and to evaluate the impact of cardiac diseases and cardiovascular risk factors in apparently healthy individuals.

Differences in zinc status and the leptin axis in anorexic and recovered adolescents and young adults: a pilot study.

Background: Evidence from animal studies suggests that leptin metabolism is associated with zinc (Zn) status. However, research investigating this relationship in adolescents and young adults with anorexia nervosa (AN) is scarce; the present study aims to fill that gap.

Methods: Serum concentrations of leptin, the soluble leptin receptor (sOB-R) and the free leptin index (FLI) were obtained in healthy control subjects (n=19), acutely ill individuals (n=14) and recovered patients with AN (n=15).

N-terminal pro brain natriuretic peptide in the management of patients in the medical emergency department (PROMPT): correlation with disease severity, utilization of hospital resources, and prognosis in a large, prospective, randomized multicentre trial.

Aims: N-terminal pro brain natriuretic peptide (NT-proBNP) is a potent marker of heart failure and other cardiac diseases. The value of NT-proBNP testing in the medical emergency department (ED) was assessed in patients >65 years old.

Methods And Results: This large, prospective, randomized, controlled, multicentre trial was conducted in six medical EDs.

Design, Setting, And Patients: A total of 1818 patients with suspected acute coronary syndrome were consecutively enrolled at the chest pain units of the University Heart Center Hamburg, the University Medical Center Mainz, and the Federal Armed Forces Hospital Koblenz, all in Germany, from 2007 to 2008.

Differences in serum zn levels in acutely ill and recovered adolescents and young adults with anorexia nervosa--a pilot study.

Preliminary evidence suggests that changes in zinc (Zn) metabolism are associated with anorexia nervosa (AN). However, data are scarce regarding potential differences in serum Zn concentrations in adolescent and young adult patients with AN. It was the aim of the present pilot study to compare serum Zn concentrations between acutely ill and remitted adolescent and young adult female patients with AN and female controls.

Midregional proadrenomedullin for prediction of cardiovascular events in coronary artery disease: results from the AtheroGene study.

Background: Midregional proadrenomedullin (MR-proADM) is a newly identified prognostic marker in heart failure. We evaluated the prognostic impact of MR-proADM in a cohort of patients with symptomatic coronary artery disease according to their clinical presentation.

Methods: We measured baseline MR-proADM concentrations in 2240 individuals from the prospective AtheroGene study and evaluated the prognostic impact on future fatal and nonfatal cardiovascular events during a follow-up period of 3.

Early reactions of brain-derived neurotrophic factor in plasma (pBDNF) and outcome to acute antidepressant treatment in patients with Major Depression.

In Major Depressive Disorder, a growing data base suggests that the onset of antidepressants' action can be detected by improvement of depressive symptoms in the first 10-14 days of treatment. Previous studies showed that the mean concentration of the brain-derived neurotrophic factor (BDNF) in blood increases during antidepressant treatment and positively correlates with amelioration of MDD symptoms. We previously showed an association between very early changes of the serum BDNF concentration and treatment outcome (Tadić et al.

Effect of autologous blood transfusion on cerebral cytokine expression.

Background: Autologous blood transfusion (ABT), for example, by means of cell saver equipment, is used to reduce the need for allogenic blood transfusion in patients with high perioperative blood loss. This study investigated the effect of blood/extracorporal surface interaction during withdrawal and retransfusion of shed autologous blood on cerebral inflammation in rats. Rats subjected to hypotension with cerebral ischemia served as positive controls.

Influence of 8 and 24-h storage of whole blood at ambient temperature on prothrombin time, activated partial thromboplastin time, fibrinogen, thrombin time, antithrombin and D-dimer.

This study evaluates the effect of whole blood storage on common coagulation parameters in order to confirm or revise acceptable storage limits as defined by current guidelines and diverse study reports. Aliquots were taken from the citrated whole blood of inpatients and outpatients (n = 147) within 4 h after blood withdrawal and after extended storage of whole blood for 8 and 24 h at ambient temperature. Aliquots were centrifuged and analyzed for prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fbg), antithrombin (AT), thrombin time (TT) and D-dimer.

Multiple marker approach to risk stratification in patients with stable coronary artery disease.

Aims: multimarker approaches for risk prediction in coronary artery disease have remained inconsistent. We assessed multiple biomarkers representing distinct pathophysiological pathways in relation to cardiovascular events in stable angina.

Methods And Results: we investigated 12 biomarkers reflecting inflammation [C-reactive protein, growth-differentiation factor (GDF)-15, neopterin], lipid metabolism (apolipoproteins AI, B100), renal function (cystatin C, serum creatinine), and cardiovascular function and remodelling [copeptin, C-terminal-pro-endothelin-1, mid-regional-pro-adrenomedullin (MR-proADM), mid-regional-pro-atrial natriuretic peptide (MR-proANP), N-terminal-pro-B-type natriuretic peptide (Nt-proBNP)] in 1781 stable angina patients in relation to non-fatal myocardial infarction and cardiovascular death (n = 137) over 3.

The early non-increase of serum BDNF predicts failure of antidepressant treatment in patients with major depression: a pilot study.

In the treatment of patients with major depressive disorder (MDD), early non-improvement of symptoms after initiation of antidepressant treatment is a highly sensitive and specific marker for final treatment failure. On the other hand, meta-analyses of clinical studies investigating serum BDNF (sBDNF) concentration before and after antidepressant treatment showed an increase of sBDNF during treatment, which was correlated with amelioration of depressive symptoms. No study has yet investigated the predictive value of early changes of sBDNF for final treatment outcome of the individual patient.

Copeptin improves early diagnosis of acute myocardial infarction.

Objectives: Early identification of myocardial infarction in chest pain patients is crucial to identify patients at risk and to maintain a fast treatment initiation.

Background: The aim of the current investigation is to test whether determination of copeptin, an indirect marker for arginin-vasopressin, adds diagnostic information to cardiac troponin in early evaluation of patients with suspected myocardial infarction.

Methods: Between January 2007 and July 2008, patients with suspected acute coronary syndrome were consecutively enrolled in this multicenter study.

Long- and short-term in vitro D-dimer stability measured with INNOVANCE D-Dimer.

In vitro D-dimer stability in plasma is widely assumed, but has not yet been documented by systematic studies using samples covering a wide range of D-dimer. We investigated the short- and long-term stability of D-dimer in clinical citrated plasma samples with normal and pathological levels. The short-term stability was analysed by measuring D-dimer fresh, after storage of plasma for 4 hours at room temperature (RT) and after an additional 24 h storage at +2 to +8 degrees C (n=40).
