Digitization in health-related self-help - Results of an online survey among self-help organizations in Germany.

Background: Nowadays, much hope and expectations are associated with digitization in the health sector. The digital change also affects health-related self-help. A nationwide survey of self-help organizations (SHOs) aimed to show chances and limitations in the use of interactive IT tools like webforums, online meetings or social media as well as digital infrastructures for their organizational management.

Clinical management of ageing people living with HIV in Europe: the view of the care providers.

Background: Although guidelines for the management of HIV infection include recommendations for aging people living with HIV (PLWH), clinical practice of European HIV care providers may vary.

Method: We performed a study using a 3-phase Delphi methodology by involving a panel of clinicians with expertise in HIV infection clinical management. The main aim of the study was to assess the care provider prospective on how HIV clinical care should be delivered to ageing PLWH.

Reinforcement magnitudes modulate subthalamic beta band activity in patients with Parkinson's disease.

We set out to investigate whether beta oscillations in the human basal ganglia are modulated during reinforcement learning. Based on previous research, we assumed that beta activity might either reflect the magnitudes of individuals' received reinforcements (reinforcement hypothesis), their reinforcement prediction errors (dopamine hypothesis) or their tendencies to repeat versus adapt responses based upon reinforcements (status-quo hypothesis). We tested these hypotheses by recording local field potentials (LFPs) from the subthalamic nuclei of 19 Parkinson's disease patients engaged in a reinforcement-learning paradigm.

Road accidents involving bicycles: configurations and injuries.

This study analyzed the most common types of accident involving bicycles and compared the frequency of injuries. The data source was the database of German In-Depth Accident Study (GIDAS). Cases consist of bicycles and their riders involved in accidents between 2000 and 2010.

Guidelines on dermatomyositis--excerpt from the interdisciplinary S2k guidelines on myositis syndromes by the German Society of Neurology.

The present guidelines on dermatomyositis (DM) represent an excerpt from the interdisciplinary S2k guidelines on myositis syndromes of the German Society of Neurology (available at www.awmf.org).

Do long-chain omega-3 fatty acids protect from atopic dermatitis?

Long-chain polyunsaturated fatty acids are essential for human nutrition. The number of double bonds determines whether a given fatty acid is termed two, three, or x times unsaturated. Depending on the distance of the first double bond from the fatty acid's methyl group, one distinguishes omega-3 fatty acids from omega-6 fatty acids.

Current diagnosis and treatment of basal cell carcinoma.

Basal cell carcinoma represents is most common tumor in fair-skinned individuals. In Germany, age-standardized incidence rates are 63 (women) and 80 (men) per 100,000 population per year. Early lesions may be difficult to diagnose merely on clinical grounds.

Differential contributions of the globus pallidus and ventral thalamus to stimulus-response learning in humans.

The ability to learn associations between stimuli, responses and rewards is a prerequisite for survival. Models of reinforcement learning suggest that the striatum, a basal ganglia input nucleus, vitally contributes to these learning processes. Our recently presented computational model predicts, first, that not only the striatum, but also the globus pallidus contributes to the learning (i.

Increased T-cell turnover is associated with spondyloarthritis in virally suppressed patients with HIV-1 infection.

Objectives: Spondyloarthritis (SpA) is one of the most frequently observed inflammatory joint diseases in HIV-1-seropositive patients. T-cells were described frequently as one of the major driving forces in SpA, therefore we tried to look for T-cell aberrancies in our HIV-positive patients with SpA.

Methods: A total of 1098 files for HIV-positive patients who attended the HIV out-patient clinic of the Department of Clinical Immunology and Rheumatology at the Medical University Hanover for at least one visit between January 2004 and December 2010 were screened for the presence of a diagnosis of SpA.

Minimally-invasive pediatric surgery in 2004: a survey including 50 German institutions.

Background: A survey on the practice of laparoscopic and thoracoscopic surgery in pediatric surgical departments in Germany is presented.

Materials And Methods: A questionnaire was sent to all 71 pediatric surgical departments in Germany (population 82 million). Fifty institutions (70%) took part in the survey that mainly included data for the year 2004: spectrum of minimally invasive operations, quantity of procedures, conversions, major complications, number of performing surgeons and residents.

Possibilities for load reductions using garment leg protectors for motorcyclists -- a technical, medical and biomechanical approach.

This study has considered demands placed on protective clothes for motorcyclists together with observed benefits and limitations for absorbing loads and preventing injuries. In this study, 1933 accidents involving injured motorcyclists, collected by an in-depth investigation team at ARU-MUH, were analysed to find the detailed injury patterns comparing persons with and without protective clothes. The parameters influencing the force reduction are discussed comparing impact speed, elasticity coefficient and thickness of the materials used in special protectors.

The human mandibular intercondylar angle measured by computed tomography.

In axial computed tomography it is possible to measure the intercondylar angle at the intersection of the longitudinal axes of the condyles. Published values range from 131 to 165 degrees. This angle was determined here in two groups of patients with (n = 22) and without (n = 12) temporomandibular joint dysfunction.

Muscle fatigue, lactate, and pyruvate in mitochondrial myopathy with progressive external ophthalmoplegia.

We studied muscle fatigue and serum lactate and pyruvate levels in 20 patients with mitochondrial myopathy with progressive external ophthalmoplegia (PEO). Fatigue was assessed in the adductor pollicis muscle (AP) using a low-intensity exercise protocol (20 min). Forces (TFs) and relaxation times of ulnar nerve evoked twitches, compound muscle action potentials (CMAPs), and maximal voluntary contractions (MVCs) were monitored.
