The foot in perspective.

The diabetic foot constitutes a tremendous challenge for patients, caregivers and the health care system. The International Consensus Document of 1999 was a milestone in the recognition of the importance and consequences of the diabetic foot. Since then, many original papers have been published in this area.Large cohort studies have given us a deeper understanding regarding factors related to the

The race for real-time photorealism

Since the 1960s, product designers, architects, lighting planners, gamers and scientific visualizaiton specialists have craved the ability to work in real-time three-dimensional photorealistic virtual worlds. The authors, one specializing in making computer graphics more convincing and the other focusing on making them faster, present the achievements and challenges in the race for real-time photo

A randomized, multicentre, double-blind, parallel-group study to assess the adverse event-related discontinuation rate with celecoxib and diclofenac in elderly patients with osteoarthritis.

Objective: To compare the adverse event (AE)-related discontinuation rate with celecoxib vs. diclofenac when given to reduce joint pain associated with knee or hip osteoarthritis (OA) in elderly patients. Methods: This was a double-blind, randomized, multicentre, parallel-group, 1-year comparison of celecoxib 200 mg once daily and diclofenac 50 mg twice daily in 925 patients with OA aged >/= 60 ye

Red cell distribution width and risk for first hospitalization due to heart failure: a population-based cohort study.

AIMS: Red cell distribution width (RDW) has been associated with cardiovascular disease, but the relation to heart failure (HF) is unclear. We investigated the association between RDW and incidence of first hospitalization due to HF in a population-based cohort. METHODS AND RESULTS: Red cell distribution width was measured in 26 784 subjects (aged 45-73 years, 61% women), without history of myocar

Non-optimal focusing of ultrasound does not affect dual frequency ultrasound measurements

In pulse-echo (PE) ultrasound measurements, the use of focused transducers is desirable for quantitative assessment of bone characteristics because of the attenuation in the overlying soft tissues. However, the variable thickness and composition of the soft tissue overlying bone affect the focal depth of the ultrasound beam and induce errors into the measurements. To compensate for the attenuation

Disease-associated patterns of disomic chromosomes in hyperhaploid neoplasms.

The chromosome number of human tumors varies widely, from near-haploidy to more than decaploidy. Overt hyperhaploid (24-34 chromosomes) tumors constitute a small minority (0.2-0.3% of cytogenetically investigated lesions), but occur in many different disease entities. In these karyotypes, most chromosomes are present in one copy; one or a few chromosomes are disomic. Published reports on 141 stric

Reliability and validity of videotaped functional performance tests in ACL-injured subjects.

Background and Purpose. In clinical practice, visual observation is often used to determine functional impairment and to evaluate treatment following a knee injury. The aim of this study was to evaluate the reliability and validity of observational assessments of knee movement pattern quality during five functional tests in subjects with an anterior cruciate ligament (ACL) injury. Method. Twelve A

Students compete in European Union Science Olympiad 2010

In April 2010, young students from 21 countries competed in EUSO - the European Union Science Olympiad. Each country sent two teams of three students to an experimental science competition. The first day, the teams helped an alien find water on Earth, and the second day, they solved a criminal case.

Down-Regulation of the Oncogene Cyclin D1 Increases Migratory Capacity in Breast Cancer and Is Linked to Unfavorable Prognostic Features.

The oncogene cyclin D1 is highly expressed in many breast cancers and, despite its proliferation-activating properties, it has been linked to a less malignant phenotype. To clarify this observation, we focused on two key components of malignant behavior, migration and proliferation, and observed that quiescent G0/G1 cells display an increased migratory capacity compared to cycling cells. We also f

Targeting CD44 Expressed on Neutrophils Inhibits Lung Damage in Abdominal Sepsis.

Neutrophil infiltration is an insidious feature in septic lung injury, although the specific adhesive mechanisms regulating pulmonary recruitment of neutrophils in polymicrobial sepsis remain elusive. The aim of this present study was to define the role of CD44 in sepsis-induced neutrophil infiltration and lung damage. Mice were treated with a monoclonal antibody against CD44 before cecal ligation

Activated Protein C-Protein C Inhibitor Complex, Activation Peptide of Carboxypeptidase B and C-Reactive Protein as Predictors of Severe Acute Pancreatitis.

Introduction: The concentration of carboxypeptidase B activation peptide (CAPAP) is proposed to be a predictor of severe acute pancreatitis. The activated protein C (APC)-protein C inhibitor (PCI; APC-PCI) complex in plasma could be useful in detecting the hypercoagulative condition in severe acute pancreatitis. Method: In this prospective study, mild (n = 50) and severe (n = 9) cases of acute pan

Diagnostics and treatment of the diabetic foot.

Every 30 s, a lower limb is amputated due to diabetes. Of all amputations in diabetic patients 85% are preceded by a foot ulcer which subsequently deteriorates to a severe infection or gangrene. There is a complexity of factors related to healing of foot ulcers including strategies for treatment of decreased perfusion, oedema, pain, infection, metabolic disturbances, malnutrition, non-weight beari

Automatic mimicry reactions as related to differences in emotional empathy

The hypotheses were based on conceiving of automatic mimicking as involved in emotio¬nal empathy. Mimicry reactions (EMG) in high- and low-empathy subjects were studied when subjects were exposed to pictures of angry or happy faces. The degree of corre¬sponden¬ce between subjects’ facial EMG reactions and their self-reported feelings was compared. The comparisons were made at different stimulus ex

Socioeconomic and occupational risk factors for venous thromboembolism in Sweden: A nationwide epidemiological study.

Our aims were to investigate possible associations between hospitalisation for venous thromboembolism (VTE) and socioeconomic and occupational factors. A nationwide database was constructed by linking Swedish census data to the Hospital Discharge Register (1990-2007). Hospital diagnoses of VTE were based on the International Classification of Diseases. Standardised incidence ratios were calculated

Food sources of fat and sex hormone receptor status of invasive breast tumors in women of the malmö diet and cancer cohort.

We examined associations between food intakes and incident breast cancer, defined by estrogen receptor (ER) and progesterone receptor (PR) status in the Malmö Diet and Cancer cohort (17,000 women aged 45-73 yr). The hazard ratios (HRs) of ER+PR+ (n = 270), ER+PR- (n = 87), and ER-PR- (n = 61) tumors and all cancer (n = 544) were estimated after 10 yr of follow-up. In multivariate analysis of ER+PR
