Abstract
AIMS The importance of diabetes-related distress for the treatment of diabetes is emphasised in national and international guidelines recommending routinely screening for psychosocial problems. Data of investigations regarding diabetes-related distress on primary care are rare in Germany though most people with diabetes are treated without insulin therapy at primary care level. METHODS Three hundred and forty-five people with diabetes mellitus type 2 (DM2, n = 336, 229 without and 107 with insulin therapy) and type 1 (DM1, n = 9) were interviewed with the PAID questionnaire in the period from 1 October 2015 to 31 December 2015 in a general practice. A PAID score ≥40 (range 0-100) was considered as high diabetes-related distress. RESULTS The mean PAID score of all participants was 3.9 ± 7.0 (DM2 without insulin 2.7 ± 6.3, DM2 with insulin therapy 6.0 ± 8.0, DM1 6.8 ± 4.9) and far below the threshold of 40 points. Only 1.2% of all responders showed high diabetes-related distress (score ≥40). People on insulin therapy with HbA1c >7.5% and with diagnosed depression prior to the study scored significantly higher. Furthermore, there are weak correlations between the PAID score and HbA1c (r = 0.253, p < 0.001), duration of diabetes (r = 0.169, p = 0.002), insulin dosage (r = 0.283, p < 0.001) and age (r = -0.129, p = 0.016). CONCLUSIONS Only 1.2% of our outpatients with diabetes on primary care level showed high diabetes-related distress. Higher rates in the current literature are probably due to not investigating on primary care level. Guidelines should consider this.

Abstract
Disturbances of the gamma-aminobutyric-acid (GABA) system have been suspected of contributing to the pathophysiology of progressive supranuclear palsy (PSP). The ability to rapidly resolve competitive action decisions, such as shifting the gaze to one particular stimulus rather than another, can be predicted by the concentration of GABA in the region of the frontal cortex relevant to eye movements. For this reason, our study measured GABA levels in seven PSP patients and eight healthy controls, using proton magnetic resonance spectroscopy, and assessed the relationship of these measurements to the remote distractor effect (RDE), an eye-movement paradigm investigating competitive action decisions. No significant differences were found in either frontal-eye-field GABA levels or RDE between PSP patients and controls.

Abstract
OBJECTIVE Interleukin-1 (IL-1) is an alleged important cytokine in osteoarthritis (OA), although the exact contribution of IL-1 to joint destruction remains unclear. Here we investigated the involvement of IL-1α and IL-1β in joint pathology during collagenase-induced OA (CiOA). METHODS CiOA was induced in wild type (WT) and IL-1αβ-/- mice. Additionally, IL-1 signaling was inhibited in WT mice with CiOA using osmotic pumps containing IL-1RA. Joint pathology was assessed using histology. Activity of cartilage-degrading enzymes was determined using antibodies against aggrecan neo-epitopes VDIPEN and NITEGE. Synovial gene expression was analyzed using quantitative real-time polymerase chain reaction (qRT-PCR). Serum protein levels were measured with Luminex or enzyme-linked immunosorbent assay (ELISA). RESULTS Synovial IL-1β expression was strongly elevated 7 days after induction of CiOA in WT mice but decreased afterwards, whereas S100A8/A9, previously described to aggravate OA, remained elevated for 21 days. Remarkably, synovial inflammation was comparable between WT and IL-1αβ-/- mice on day 7 of CiOA. In line, synovial mRNA expression of genes involved in IL-1 signaling and inflammatory mediators was comparable between WT and IL-1αβ-/- mice, and serum levels for Keratinocyte Chemoattractant (KC)/IL-6/S100A8/S100A9/IL-10 were equal. Synovial matrix metalloproteinase (MMP)/aggrecanase expression and activity in cartilage was not different in WT and IL-1αβ-/- mice on day 7 of CiOA. Cartilage destruction on day 42 was not different between WT and IL-1αβ-/- mice, which was supported by our finding that IL-1RA treatment in WT mice with CiOA did not alter joint destruction. CONCLUSIONS IL-1α and IL-1β are not involved in synovial inflammation and cartilage destruction during CiOA, implicating that other mediators are responsible for the joint damage.

Abstract
OBJECTIVE Low-density lipoproteins (LDL) in inflamed synovium is oxidized and taken-up by synoviocytes. In this study, we investigate whether direct injection of oxidized LDL (oxLDL) into a normal murine knee joint induces joint pathology and whether synovial macrophages are involved in that process. DESIGN Synovium was obtained from end-stage osteoarthritis (OA) patients in order to analyze LDL-uptake. Murine knee joints were injected five consecutive days with oxLDL, LDL, or vehicle (phosphate buffered saline (PBS)). This procedure was repeated in mice depleted of synovial macrophages by intra-articular injection of clodronate liposomes 7 days prior to the consecutive injections. Joint pathology was investigated by immunohistochemistry, flow cytometry (FCM) and synovial RNA expression and protein production. RESULTS Synovial tissue of OA patients showed extensive accumulation of apolipoprotein B. Multiple injections of oxLDL in murine knee joints significantly increased TGF-β activity in synovial wash-outs, but did not induce catabolic or inflammatory processes. In contrast, repeated injections of oxLDL in macrophage-depleted knee joints led to increased synovial thickening in combination with significantly upregulated protein and RNA levels of CCL2 and CCL3. FCM-analyses revealed increased presence of monocytes and neutrophils in the synovium, which was confirmed by immunohistochemistry. Also protein levels of S100A8/A9 were significantly increased in synovial wash-outs of oxLDL-injected joints, as was expression of aggrecanase-induced neo-epitopes. Interestingly, no raise in TGF-β concentrations was measured in macrophage-depleted joints. CONCLUSIONS OxLDL can affect joint pathology, since synovial macrophages promote anabolic processes after oxLDL injections. In absence of synovial macrophages, however, oxLDL induces production of pro-inflammatory mediators and aggrecanase activity combined with increased influx of monocytes and neutrophils.

Abstract
Background: The JEVIN trial started as a cross-sectional study in 1989/90 in Jena, a city of the former German Democratic Republic. At that time, the centralized diabetes care system was broken down and restarted 10 years later; structured treatment and teaching programs were implemented, blood glucose self-monitoring, insulin pump-systems and analogue insulin were introduced. We surveyed people with type-1-diabetes of the baseline JEVIN trial in a 20-year follow-up. Methods: 131 patients with type-1-diabetes were analyzed in 1989/90. Of the living population in 2009/10 (n=104), 83 persons were identified and 75 persons with a mean diabetes duration of 35 years were reexamined regarding HbA1c, self-monitoring, diabetes therapy, severe hypoglycemia, diabetic late complications and compared with the results of the same persons in 1989/90. Results: HbA1c decreased from 57.1 mmol/mol in 1989/90 to 52.7 mmol/mol in 2009/10 (7.4 -7.0%; p=0.049). Self-monitoring of blood glucose increased from 2 to 35 tests/week (p<0.001). 100%-use of animal insulin changed to human and analogue insulin therapy. The incidence of severe hypoglycemia increased from 0.1 to 0.16/patient-year. Retinopathy increased from 29 to 69% (p<0.001), nephropathy from 5 to 27% (p<0.001) and neuropathy from 13 to 43% (p<0.001). 17% had no diabetic late complications. Conclusions: The JEVIN trial shows a significant improve in HbA1c in the past 20 years. Severe hypoglycemia occurred rarely and 17% were still free of any diabetic late complication after 35 years of diabetes. This indicates a good quality of diabetes care in a German setting.

Abstract
INTRODUCTION The radiation protection in the veterinary medicine is to be followed especially for persons occupationally exposed to ionizing radiation as well as for further persons who must help with the holding of an animal during radiography. Dose measurements were carried out in a veterinary clinic. Thereby, the doses were determined which occur at different points on the body of persons restraining the animal, with and without the protection of lead rubber apron. The result shows that a crouching position is counterproductive, because on the unprotected head including the eyes and thyroid gland up to the threefold dose compared to an upright position is reached. This instruction - besides to turn away the head or to close even the eyes - may require often that the radiograph must be repeated for a diagnostic image quality. Therewith, the conception of the radiation protection is in no way followed. The condition for an optimum protection against unnecessary radiation for the staff as well as necessary further persons is a suitable education by practically oriented teachers.

Abstract
AIMS The relationship between 1- and 2-h glucose levels following an oral glucose tolerance test (OGTT) and long-term mortality was evaluated. METHODS Over a 33-year period, 2138 individuals were followed for all-cause mortality. Fasting and post-OGTT glucose parameters categorized the cohort according to baseline glycaemic status. Four categories were established according to 1- and 2-h glucose levels (in mmol/l): group A = 1 h ≤ 8.8 and 2 h < 7.8; group B = 1 h > 8.6 and 2 h < 7.8; group C = 1 h ≤ 8.6 and 2 h = 7.8-11.1 (impaired glucose tolerance); group D = 1 h > 8.6 and 2 h = 7.8-11.1 (impaired glucose tolerance). Individuals with diabetes at baseline were excluded from the cohort. RESULTS By August 2013, 51% of the study cohort had died. The worst prognosis occurred in group D (73.8% mortality), followed by groups C (67.5%), B and A (57.9% and 41.6%, respectively). When the 2-h glucose value is 'normal' (< 7.8 mmol/l), the 1-h glucose value > 8.6 mmol/l is an important predictor of mortality (28% increased risk) compared with group A, controlling for sex, age, smoking, BMI, systolic and diastolic blood pressures. A gradual increased hazard for mortality was seen by study group (hazard ratio = 1.28, 1.60 and 1.76, for groups B, C and D, respectively; group A = reference). CONCLUSIONS A 1-h glucose value > 8.6 mmol/l predicts mortality even when the 2-h level is < 7.8 mmol/l. However, when the 2-h level is in the impaired glucose tolerance range, the hazard for mortality rises significantly independent of the 1-h value. Individuals at risk for developing diabetes could be identified earlier using the 1-h threshold value of 8.6 mmol/l, which could avert progression to diabetes and increased mortality..

Abstract
UNLABELLED Nondestructive testing is a common method for root cause investigations of malfunction of mechanical devices, for example, medical devices for drug dose delivery. Radiography is a method that has the advantage that it is possible to see through the sample. In this work we are using neutron radiography to observe drug distribution in drug injection devices during the injection process and as post-injection examination. Using neutrons it is possible to show small amounts of liquid in capillaries, and foam bubbles are shown with great contrast compared to metal and glass. The investigation has two parts optimized for high spatial and high temporal resolution, respectively. Using high spatial resolution it is possible to resolve the thin films of drug product in foam and even to detect the drug residues in the injection needle. Switching to high temporal resolution we demonstrate that it is possible to follow the injection process. Spatio-temporal data sets of the injection process were acquired using remotely triggered injection devices and a camera allowing sub-second frame rates.The motion analysis required the application of an edge-preserving spatio-temporal denoising filter to improve the signal-to-noise ratio. After filtering it is possible to detect relevant edges and extract motion curves from the spatio-temporal data. LAY ABSTRACT Neutron imaging is a nondestructive method based on radiography using neutrons and is suitable for detecting small amounts of aqueous liquids even in metallic casing/sheath/tubing. This property has here been used to visualize the distribution of a drug product in a syringe needle of a drug injection device. In the static case the method clearly showed the difference between needles that were empty, full, or contained a mix of gas and liquid. A second investigation was aimed to visualize the dynamic behavior of an auto-injector device. In this experiment the imaging method was capable of following the injection phase of the device. By analyzing the acquired images in time and space it is possible to measure the injection velocity curves of the piston and drug, respectively.

Abstract
Objective: Target HbA1c values given in the most National Therapeutic Guidelines for patients with diabetes and cut-off HbA1c values for diabetes diagnosis are usually not taking the age of the respective patients into account; despite the fact that an increase in HbA1c in subjects without diabetes with age is known for some time. In order to further quantify the association between age and HbA1c in non-diabetic subjects an analysis of one German register was performed. Methods: In this cross-sectional study we analyzed data from 7 699 visits of 2 921 patients without diabetes (age 46.6 y [range 18-93 y]; 69.1% women; BMI 27.6±6.4 kg/m²) who had at least one HbA1c and blood glucose measurement. Data were drawn from an electronic patient record system (EMIL™) in which data were collected between 01/1992 and 01/2014. The patients were divided in 6 age groups (< 30 years [n=1 057];>30-40 years [n=1 160];>40-50 years [n=1 693];>50-60 years [n=1 523];>60-70 years [n=1 310];>70 years [n=956]) and the HbA1c values of these groups were compared. Patients with: gestational diabetes, use of systemic glucocorticoids, malignant neoplasm, age<18 y at time of first visit and IGT were excluded. HbA1c measurements were DCCT adjusted. Results: Patients with age>70 years have a 0.47% [5.14 mmol/mol] higher HbA1c compared to those<30 years. The mean HbA1c of the age groups was:<30 4.98% [30.96 mmol/mol],>30-40 5.07% [31.99 mmol/mol],>40-50 5.17% [33.10 mmol/mol],>50-60 5.33% [34.79 mmol/mol],>60-70 5.42% [35.79 mmol/mol] and>70 years 5.45% [36.10 mmol/mol]. In a multiple linear model the regression coefficient for each year of age increase was β=0.0074 (p<0.001); thus age results in an increase of 0.074% in HbA1c per decade. Conclusion: HbA1c increases significantly with ageing in people without diabetes. The use of different cut-off values for every age range for diagnosis of diabetes should be discussed.

Abstract
Acute rejection is a risk factor for inferior long-term kidney transplant survival. Although T cell immunity is considered the main effector in clinical acute rejection, the role of myeloid cells is less clear. Expression of S100 calcium-binding protein A8 (S100A8) and S100A9 was evaluated in 303 biopsies before and after transplantation from 190 patients. In two independent cohorts of patients with acute rejection (n = 98 and n = 11; mostly cellular rejections), high expression of S100 calcium-binding protein A8 (S100A8) and A9 (S100A9) was related to improved graft outcome. Mechanisms of action of the S100 molecules were investigated. In the graft and peripheral blood cells, S100A8 and S100A9 expression correlated with myeloid-derived suppressor markers. In line with this finding, recombinant S100A8 and S100A9 proteins inhibited maturation and the allogeneic T cell stimulatory capacity of dendritic cells. S100A9 enhanced the production of reactive oxygen species by macrophages, which suppressed T cell activity at low concentrations in the form of hydrogen peroxide. Intragraft S100A8 and S100A9 expression linked to reduced expression of T cell immunity and tissue injury markers and higher expression of immune regulatory molecules. This study sheds new light on the importance of myeloid cell subsets in directing the outcome of T cell-mediated acute rejection.
