RESUMO

Fisheries social-ecological systems (SES) in the North Sea region confront multifaceted challenges stemming from environmental changes, offshore wind farm expansion, and marine protected area establishment. In this paper, we demonstrate the utility of a Bayesian Belief Network (BN) approach in comprehensively capturing and assessing the intricate spatial dynamics within the German plaice-related fisheries SES. The BN integrates ecological, economic, and socio-cultural factors to generate high-resolution maps of profitability and adaptive capacity potential (ACP) as prospective management targets. Our analysis of future scenarios, delineating changes in spatial constraints, economics, and socio-cultural aspects, identifies factors that will exert significant influence on this fisheries SES in the near future. These include the loss of fishing grounds due to the installation of offshore wind farms and marine protected areas, as well as reduced plaice landings due to climate change. The identified ACP hotspots hold the potential to guide the development of localized management strategies and sustainable planning efforts by highlighting the consequences of management decisions. Our findings emphasize the need to consider detailed spatial dynamics of fisheries SES within marine spatial planning (MSP) and illustrate how this information may assist decision-makers and practitioners in area prioritization. We, therefore, propose adopting the concept of fisheries SES within broader integrated management approaches to foster sustainable development of inherently dynamic SES in a rapidly evolving marine environment.

RESUMO

OBJECTIVE: Telehealth is rapidly gaining ground from usual treatment, not least because of coronavirus disease 2019 (COVID-19) measures. Within rheumatology, telehealth has been used for, inter alia, follow-up for patients with rheumatoid arthritis (RA) with low disease activity or in remission. This study aims to assess the cost-effectiveness of such a telehealth intervention. METHOD: In a randomized controlled trial, 294 patients were randomized into patient-reported outcome-based telehealth follow-up by either a nurse (PRO-TN) or a rheumatologist (PRO-TR) or to conventional outpatient follow-up (control). Cost-effectiveness was evaluated using costs per quality-adjusted life-year (QALY) gained. Individual-level healthcare and productivity costs were retrieved from national Danish registers. Incremental cost-effectiveness ratios were calculated for the intervention groups compared to the control group. Bootstrapping with 10 000 replications was used to obtain confidence intervals. Furthermore, cost-effectiveness acceptability curves were generated. RESULTS: The cost comparison showed that PRO-TR was significantly less costly than the control group, whereas the relative reduction in costs for PRO-TN was not significant. The telehealth groups experienced minor, non-significant declines in QALYs, whereas the control group experienced a slight, non-significant increase. The cost-effectiveness analysis showed that for PRO-TR, the willingness to accept a QALY loss was 89 328 EUR. A similar but smaller and non-significant result was seen for PRO-TN. CONCLUSION: PRO-TR and PRO-TN seem to cost less but provide broadly similar health outcomes compared with conventional follow-up. Between the intervention groups, PRO-TR was significantly less costly. More studies are needed to conclude whether rheumatologist- or nurse-led telehealth is more cost-effective than conventional follow-up.

RESUMO

Purpose Young patients represent a particularly vulnerable group regarding vocational prognosis after an acquired brain injury (ABI). We aimed to investigate how sequelae and rehabilitation needs are associated with vocational prognosis up to 3 years after an ABI in 15-30-year-old patients. Methods An incidence cohort of 285 patients with ABI completed a questionnaire on sequelae and rehabilitation interventions and needs 3 months after the index hospital contact. They were followed-up for up to 3 years with respect to the primary outcome "stable return to education/work (sRTW)", which was defined using a national register of public transfer payments. Data were analyzed using cumulative incidence curves and cause-specific hazard ratios. Results Young individuals reported a high frequency of mainly pain-related (52%) and cognitive sequelae (46%) at 3 months. Motor problems were less frequent (18%), but negatively associated with sRTW within 3 years (adjusted HR 0.57, 95% CI 0.39-0.84). Rehabilitation interventions were received by 28% while 21% reported unmet rehabilitation needs, and both factors were negatively associated with sRTW (adjusted HR 0.66, 95% CI 0.48-0.91 and adjusted HR 0.72, 95% CI 0.51-1.01). Conclusions Young patients frequently experienced sequelae and rehabilitation needs 3 months post ABI, which was negatively associated with long-term labor market attachment. The low rate of sRTW among patients with sequelae and unmet rehabilitation needs indicates an untapped potential for ameliorated vocational and rehabilitating initiatives targeted at young patients.

RESUMO

BACKGROUND: Head injuries are common injury in the fire service; however, very little data exist on the risks this may pose to the development of post-traumatic stress disorder (PTSD) and depression in this high-risk population. AIMS: Our study aimed to compare levels of PTSD and depression symptoms in firefighters with a line-of-duty head injury, non-line-of-duty head injury and no head injury. METHODS: In this cross-sectional study, we assessed current PTSD and depression symptoms as well as retrospective head injuries. RESULTS: Seventy-six per cent of the total sample reported at least one head injury in their lifetime. Depression symptoms were significantly more severe among firefighters with a line-of-duty head injury compared to those with no head injury, but not compared to those who sustained a non-line-of-duty head injury. Depression symptoms did not differ between firefighters with a non-line-of-duty head injury and those with no head injury. PTSD symptoms were significantly more severe among firefighters with a line-of-duty head injury compared to both firefighters with no head injury and those with a non-line-of-duty head injury. CONCLUSIONS: We found that firefighters who reported at least one line-of-duty head injury had significantly higher levels of PTSD and depression symptoms than firefighters who reported no head injuries. Our findings also suggest head injuries sustained outside of fire service could have less of an impact on the firefighter's PTSD symptom severity than head injuries that occur as a direct result of their job.

RESUMO

OBJECTIVE: To evaluate the cost-effectiveness of incisional negative pressure wound therapy (iNPWT) in preventing surgical site infection in obese women after caesarean section. DESIGN: A cost-effectiveness analysis conducted alongside a clinical trial. SETTING: Five obstetric departments in Denmark. POPULATION: Women with a pregestational body mass index (BMI) ≥30 kg/m2 . METHOD: We used data from a randomised controlled trial of 876 obese women who underwent elective or emergency caesarean section and were subsequently treated with iNPWT (n = 432) or a standard dressing (n = 444). Costs were estimated using data from four Danish National Databases and analysed from a healthcare perspective with a time horizon of 3 months after birth. MAIN OUTCOME MEASURES: Cost-effectiveness based on incremental cost per surgical site infection avoided and per quality-adjusted life-year (QALY) gained. RESULTS: The total healthcare costs per woman were €5793.60 for iNPWT and €5840.89 for standard dressings. Incisional NPWT was the dominant strategy because it was both less expensive and more effective; however, no statistically significant difference was found for costs or QALYs. At a willingness-to-pay threshold of €30,000, the probability of the intervention being cost-effective was 92.8%. A subgroup analysis stratifying by BMI shows that the cost saving of the intervention was mainly driven by the benefit to women with a pre-pregnancy BMI ≥35 kg/m2 . CONCLUSION: Incisional NPWT appears to be cost saving compared with standard dressings but this finding is not statistically significant. The cost savings were primarily found in women with a pre-pregnancy BMI ≥35 kg/m2 . TWEETABLE ABSTRACT: Prophylactic incisional NPWT reduces the risk of SSI after caesarean section and is probably dominant compared with standard dressings #healtheconomics.

RESUMO

OBJECTIVE: To evaluate the reduction of surgical site infections by prophylactic incisional negative pressure wound therapy compared with standard postoperative dressings in obese women giving birth by caesarean section. DESIGN: Multicentre randomised controlled trial. SETTING: Five hospitals in Denmark. POPULATION: Obese women (prepregnancy body mass index (BMI) ≥30 kg/m2 ) undergoing elective or emergency caesarean section. METHOD: The participants were randomly assigned to incisional negative pressure wound therapy or a standard dressing after caesarean section and analysed by intention-to-treat. Blinding was not possible due to the nature of the intervention. MAIN OUTCOME MEASURES: The primary outcome was surgical site infection requiring antibiotic treatment within the first 30 days after surgery. Secondary outcomes included wound exudate, dehiscence and health-related quality of life. RESULTS: Incisional negative pressure wound therapy was applied to 432 women and 444 women had a standard dressing. Demographics were similar between groups. Surgical site infection occurred in 20 (4.6%) women treated with incisional negative pressure wound therapy and in 41 (9.2%) women treated with a standard dressing (relative risk 0.50, 95% CI 0.30-0.84; number needed to treat 22; P = 0.007). The effect remained statistically significant when adjusted for BMI and other potential risk factors. Incisional negative pressure wound therapy significantly reduced wound exudate whereas no difference was found for dehiscence and quality of life between the two groups. CONCLUSION: Prophylactic use of incisional negative pressure wound therapy reduced the risk of surgical site infection in obese women giving birth by caesarean section. TWEETABLE ABSTRACT: RCT: prophylactic incisional NPWT versus standard dressings postcaesarean in 876 women significantly reduces the risk of SSI.

RESUMO

BACKGROUND: In emergency situations it is essential to get access to medical treatment as early as possible. In Germany, the time interval from alarm to arrival should be less than 10-15 min. The emergency medical service (EMS) cannot comply with this recommendation in approximately 10% of the emergencies in Baden-Württemberg. In addition to the traditional EMS system, a voluntary system of first responders has been developed over the last years to reduce this interval. They are incorporated into the alarm system of the traditional EMS and are alarmed as soon as an emergency call arrives. Data on process times (from alarm to begin of treatment or duration of treatment until arrival of EMS) and quality are rare. In Baden-Württemberg, the emergency aid "Deutsche Lebens-Rettungs-Gesellschaft e.V. (DLRG)" Nordhardt can only estimate times and quality of primary care. The objective of this analysis was to describe and evaluate such a first responder system. METHODS: The presented study investigated the emergency responses of a first responder system in Nordhardt, close to Karlsruhe, Germany. A total of 367 emergency data sets from 2017 containing information on operating time, medical history, suspected diagnosis and medical treatment, were evaluated. Of these, 363 anonymized emergency records including the complete information (concerning process time and medical treatment) were analyzed. The focus was on different time intervals from alarm to treatment and until arrival of the EMS. Additionally, the quality of medical treatment and the measured vital data were examined. RESULTS: The median response time and time to access to the patient was 2 min in both. The patient was reached within approximately 4 min and treated for another 5 min until the EMS arrived. In two thirds of the patients, the vital parameters were measured, 5 patients were resuscitated, 23 received supplementary oxygen, 4 patients were ventilated and 11 patients suffering from hypoglycemia showed a clinical benefit from the early treatment. A total of 50 trauma patients were treated, 5 with cervical spine stabilization and 38 received a body check. CONCLUSION: The first responders from Nordhardt received an emergency call nearly every day. In two thirds of the calls they were faster than the EMS as they usually have local sites with a shorter distance to the emergency scene where they are able to deal with critical medical cases until the EMS arrives. Despite the small case numbers, it could be concluded that the early medical treatment with respect to resuscitation based on earlier arrival on site may help to increase the survival rate of patients. The first responders were also able to manage airway problems with additional oxygen or other airway devices. Other medical treatment performed by the first responders, such as administration of glucose in hypoglycemic patients positively affected the patient's condition. There is a tactical advantage to include first responders in traditional EMS services. Further studies are needed to examine these questions in larger samples also over a longer time period. Standardization and digitalization of the records could help to gain more data in this field.

RESUMO

BACKGROUND: Oxygen is liberally administered in intensive care units (ICUs). Nevertheless, ICU doctors' preferences for supplementing oxygen are inadequately described. The aim was to identify ICU doctors' preferences for arterial oxygenation levels in mechanically ventilated adult ICU patients. METHODS: In April to August 2016, an online multiple-choice 17-part-questionnaire was distributed to 1080 ICU doctors in seven Northern European countries. Repeated reminder e-mails were sent. The study ended in October 2016. RESULTS: The response rate was 63%. When evaluating oxygenation 52% of respondents rated arterial oxygen tension (PaO2 ) the most important parameter; 24% a combination of PaO2 and arterial oxygen saturation (SaO2 ); and 23% preferred SaO2 . Increasing, decreasing or not changing a default fraction of inspired oxygen of 0.50 showed preferences for a PaO2 around 8 kPa in patients with chronic obstructive pulmonary disease, a PaO2 around 10 kPa in patients with healthy lungs, acute respiratory distress syndrome or sepsis, and a PaO2 around 12 kPa in patients with cardiac or cerebral ischaemia. Eighty per cent would accept a PaO2 of 8 kPa or lower and 77% would accept a PaO2 of 12 kPa or higher in a clinical trial of oxygenation targets. CONCLUSION: Intensive care unit doctors preferred PaO2 to SaO2 in monitoring oxygen treatment when peripheral oxygen saturation was not included in the question. The identification of PaO2 as the preferred target and the thorough clarification of preferences are important when ascertaining optimal oxygenation targets. In particular when designing future clinical trials of higher vs lower oxygenation targets in ICU patients.

RESUMO

Haemocyanin is the copper-containing respiratory protein present in many arthropods. In the hexapods, respiratory proteins had long been considered unnecessary as sufficient O2 was thought to be obtained via the trachea. Nevertheless, many ametabolous and hemimetabolous hexapod species actually possess haemocyanin. Here we investigated the occurrence of haemocyanin in Collembola (springtails). Haemocyanin was found in 22 collembolan species of the suborders Symphypleona, Tomoceroidea and Entomobryomorpha, demonstrating its widespread occurrence. No haemocyanin was identified in 16 species of these taxa, and it appears to be absent in Poduromorpha. The presence of haemocyanin does not correlate with either the phylogenetic history or lifestyle of the investigated species. We further investigated the function of haemocyanin in Folsomia candida (Entomobryomorpha) by applying different hypoxia regimes. Whereas short-term (1 h) and mild (10% O2 ) hypoxia led to a decrease in haemocyanin mRNA, strong hypoxia (24 h, 1.5% O2 ) resulted in a ∼4300-fold increase in haemocyanin expression. Hypoxia induction of haemocyanin could not be demonstrated in evolutionarily more advanced Hexapoda, where it is restricted to the embryo. The results indicate (1) an important role of haemocyanin in the oxygen supply of F. candida, which may be adaptive in the potentially hypoxic environment in the soil, and (2) a change in haemocyanin function in hexapod evolution.

RESUMO

BACKGROUND: Postoperative wound complications are common following surgical procedures. Negative-pressure wound therapy (NPWT) is well recognized for the management of open wounds and has been applied recently to closed surgical incisions. The evidence base to support this intervention is limited. The aim of this study was to assess whether NPWT reduces postoperative wound complications when applied to closed surgical incisions. METHODS: This was a systematic review and meta-analysis of randomized clinical trials of NPWT compared with standard postoperative dressings on closed surgical incisions. RESULTS: Ten studies met the inclusion criteria, reporting on 1311 incisions in 1089 patients. NPWT was associated with a significant reduction in wound infection (relative risk (RR) 0·54, 95 per cent c.i. 0·33 to 0·89) and seroma formation (RR 0·48, 0·27 to 0·84) compared with standard care. The reduction in wound dehiscence was not significant. The numbers needed to treat were three (seroma), 17 (dehiscence) and 25 (infection). Methodological heterogeneity across studies led to downgrading of the quality of evidence to moderate for infection and seroma, and low for dehiscence. CONCLUSION: Compared with standard postoperative dressings, NPWT significantly reduced the rate of wound infection and seroma when applied to closed surgical wounds. Heterogeneity between the included studies means that no general recommendations can be made yet.

RESUMO

3D asymmetries are major degradation mechanisms in inertial-confinement fusion implosions at the National Ignition Facility (NIF). These asymmetries can be diagnosed and reconstructed with the neutron imaging system (NIS) on three lines of sight around the NIF target chamber. Conventional tomographic reconstructions are used to reconstruct the 3D morphology of the implosion using NIS [Volegov et al., J. Appl. Phys. 127, 083301 (2020)], but the problem is ill-posed with only three imaging lines of sight. Asymmetries can also be diagnosed with the real-time neutron activation diagnostics (RTNAD) and the neutron time-of-flight (nToF) suite. Since the NIS, RTNAD, and nToF each sample a different part of the implosion using different physical principles, we propose that it is possible to overcome the limitations of too few imaging lines of sight by performing 3D reconstructions that combine information from all three heterogeneous data sources. This work presents a new machine learning-based reconstruction technique to do just this. By using a simple physics model and group of neural networks to map 3D morphologies to data, this technique can easily account for data of multiple different types. A simple proof-of-principle is presented, demonstrating that this technique can accurately reconstruct a hot-spot shape using synthetic primary neutron images and a hot-spot velocity vector. In particular, the hot-spot's asymmetry, quantified as spherical harmonic coefficients, is reconstructed to within ±4% of the radius in 90% of test cases. In the future, this technique will be applied to actual NIS, RTNAD, and nToF data to better understand 3D asymmetries at the NIF.

RESUMO

Osteosarcoma is the most common bone tumor in dogs. However, current literature focuses primarily on appendicular osteosarcoma. This study examined the prognostic value of histological and clinical factors in flat and irregular bone osteosarcomas and hypothesized that clinical factors would have a significant association with survival time while histological factors would not. All osteosarcoma biopsy samples of the vertebra, rib, sternum, scapula, or pelvis were reviewed while survival information and clinical data were obtained from medical records, veterinarians, and owners. Forty-six dogs were included in the analysis of histopathological variables and 27 dogs with complete clinical data were included in the analysis of clinical variables. In the histopathologic cox regression model, there was no significant association between any histologic feature of osteosarcoma, including grade, and survival time. In the clinical cox regression model, there was a significant association between the location of the tumor and survival time as well as between the percent elevation of alkaline phosphatase (ALP) above normal and survival time. Controlling for ALP elevation, dogs with osteosarcoma located in the scapula had a significantly greater hazard for death (2.8) compared to dogs with tumors in other locations. Controlling for tumor location, every 100% increase in ALP from normal increased the hazard for death by 1.7. For canine osteosarcomas of the flat and irregular bones, histopathological features, including grade do not appear to be rigorous predictors of survival. Clinical variables such as increased ALP levels and tumor location in the scapula were associated with decreased survival times.

RESUMO

STUDY OBJECTIVE: Fibromyalgia syndrome (FMS) is characterized by e. g. chronic, multilocular pain, and mental health problems. In Germany, patients with FMS are treated in somatic and psychosomatic rehabilitation centers - specialized for rheumatic diseases (somatic) or psychosomatic diseases. The aim of this study is to identify the status quo of FMS patients' access routes to the rehabilitation system, and to identify their predictors for being assigned to one or the other indication group. METHOD: Our cohort consists of 197 FMS patients from 3 psychosomatic (M=49.9 years) and 223 FMS patients (M=50.2 years) from 3 somatic rehabilitation centers. At the beginning of rehabilitation, patients filled out a questionnaire packet to identify their access routes to the rehabilitation centers and to record patients' disease-related, psychosocial and socio-demographic characteristics. To analyze the results we used descriptive calculations, calculated bivariate correlations, and conducted binary logistic regression analysis for the prediction of group membership. RESULTS: The access routes of FMS patients to a somatic or a psychosomatic rehabilitation center were often similar. Some items revealed significant group differences, i. e., a higher primary -rejection rate, longer waiting period between application for rehabilitation and its approval, and between the application itself and initiation of psychosomatic rehabilitation in comparison to somatic FMS patients. Prior experience of out-patient psychotherapy, and expectations ("psychological support") for the rehabilitation were predictive patient characteristics for the assignment into a psychosomatic rehabilitation center. Marriage, motivation, and expectations ("physical improvement" and "interaction with other patients") for the rehabilitation were predictive patient characteristics for the assignment in a somatic rehabilitation center. The predictors clarified 32% of the variance of group membership. CONCLUSION: Our results provide initial evidence of how FMS patients access the German rehabilitation system and which of their characteristics are responsible for being assigned to a particular rehabilitation setting.

RESUMO

In order to understand how close current layered implosions in indirect-drive inertial confinement fusion are to ignition, it is necessary to measure the level of alpha heating present. To this end, pairs of experiments were performed that consisted of a low-yield tritium-hydrogen-deuterium (THD) layered implosion and a high-yield deuterium-tritium (DT) layered implosion to validate experimentally current simulation-based methods of determining yield amplification. The THD capsules were designed to reduce simultaneously DT neutron yield (alpha heating) and maintain hydrodynamic similarity with the higher yield DT capsules. The ratio of the yields measured in these experiments then allowed the alpha heating level of the DT layered implosions to be determined. The level of alpha heating inferred is consistent with fits to simulations expressed in terms of experimentally measurable quantities and enables us to infer the level of alpha heating in recent high-performing implosions.

RESUMO

Dendritic cells (DCs), nature's adjuvant, must mature to sensitize T cells. However, although the maturation process is essential, it is not yet fully understood at the molecular level. In this study, we investigated the course of expression of the unique hypusine-containing protein eukaryotic initiation factor 5A (eIF-5A), which is part of a particular RNA nuclear export pathway, during in vitro generation of human DCs. We show that eIF-5A expression is significantly upregulated during DC maturation. Furthermore, an inhibitor of the hypusine modification, GC7 (N(1)-guanyl-1, 7-diaminoheptane), prevents CD83 surface expression by apparently interfering with nucleocytoplasmic translocation of the CD83 mRNA and, importantly, significantly inhibits DC-mediated T lymphocyte activation. The data presented suggest that CD83 mRNA is transported from the nucleus to the cytoplasm via a specific nuclear export pathway and that hypusine formation appears to be essential for the maturation of functional DCs. Therefore, pharmacological interference with hypusine formation may provide a new possibility to modulate DC function.

RESUMO

Background: The course of coronavirus disease 2019 (COVID-19) seems to be aggravated by air pollution, and some industrial chemicals, such as the perfluorinated alkylate substances (PFASs), are immunotoxic and may contribute as well. Methods: From Danish biobanks, we obtained plasma samples from 323 subjects aged 30-70 years with known SARS-CoV-2 infection. The PFAS concentrations measured at the background exposures included five PFASs known to be immunotoxic. Register data was obtained to classify disease status, other health information, and demographic variables. We used ordinal and ordered logistic regression analyses to determine associations between PFAS concentrations and disease outcome. Results: Plasma-PFAS concentrations were higher in males, in subjects with Western European background, and tended to increase with age, but were not associated with the presence of chronic disease. Of the study population, 108 (33%) had not been hospitalized, and of those hospitalized, 53 (16%) had been in intensive care or were deceased. Among the five PFASs considered, perfluorobutanoic acid (PFBA) showed an odds ratio (OR) of 2.19 (95% confidence interval, CI, 1.39-3.46) for increasing severities of the disease, although the OR decreased to 1.77 (95% CI, 1.09, 2.87) after adjustment for age, sex, sampling site and interval between blood sampling and diagnosis. Conclusions: Measures of individual exposures to immunotoxic PFASs included PFBA that accumulates in the lungs. Elevated plasma-PFBA concentrations were associated with an increased risk of more severe course of CIVID-19. Given the low background exposure levels in this study, the role of PFAS exposure in COVID-19 needs to be ascertained in populations with elevated exposures.

RESUMO

It is reported about the case of a 3-year-old girl who was admitted to hospital with high fever, vomiting, skin rash, dehydration, suspected staphyloderma and for exclusion of a severe acute respiratory syndrome coronavirus type 2-infection (SARS-CoV­2 infection). The suspicion of a toxic shock syndrome, among other inflammatory diseases as differential diagnoses, was based on profound erythroderma and arterial hypotension. The diagnostic pathway, treatment and clinical course of this rare disease are described.

RESUMO

Epimorphin was recently described as a mesenchymal factor modulating morphogenesis of murine mammary ducts, skin, liver, and lung in vitro. In this study epimorphin was analyzed in a human, pancreatic adenocarcinoma cell line (A818-6) which develops single layer epithelial hollow spheres resembling normal pancreatic ductal structures in vitro. Soluble 34- and 31-kD isoforms of epimorphin were found in the culture supernatant of A818-6 cells. In lysates of A818-6 cells we detected the 34-and 31-kD isoforms and the dimers, and in lysates of fibroblasts the 150-kD tetramers of epimorphin additionally. A neutralizing monoclonal antibody against epimorphin (MC-1) efficiently blocked the development of hollow sphere structures from A818-6 cells. Coculture of A818-6 cells with fibroblasts stimulated the development of hollow sphere structures in general and increased differentiation in 5-6-d-old hollow spheres. A818-6 hollow sphere development in the presence of fibroblasts was also blocked by MC-1. In this novel system for human duct-like differentiation of pancreatic epithelial cells, we provide evidence for an autocrine and paracrine function of epimorphin as a major mediator for morphogenesis.

RESUMO

Reducing the workload of the beta cell by inhibiting insulin secretion may provide beneficial effects for patients with type 2 diabetes. The aim of this study was to investigate the effect of NN414, a beta cell selective potassium channel opener in patients with type 2 diabetes. 24 patients were treated for seven days (placebo, 1.5, 4.5, and 10 mg/kg). In accordance with the pharmacological profile a significant and selective inhibition of insulin secretion was observed (1 h post dose). There were no statistically significant effects on overall glycaemic control. Based on OGTT derived parameters a borderline significant improvement in beta-cell function (1st and 2nd phase insulin secretion) was observed from Day 1 to Day 7.
