Activation of μ receptors by SR-17018 through a distinctive mechanism.

Agonists at μ opioid receptors relieve acute pain, however, their long-term use is limited by side effects, which may involve β-arrestin2. Agonists biased against β-arrestin2 recruitment may be advantageous. However, the classification of bias may be compromised by assays utilising overexpressed μ receptors which overestimate efficacy for G-protein activation.

The Biggest Loser Thinks Long-Term: Recency as a Predictor of Success in Weight Management.

Only a minority of participants in behavioral weight management lose weight significantly. The ability to predict who is likely to benefit from weight management can improve the efficiency of obesity treatment. Identifying predictors of weight loss can also reveal potential ways to improve existing treatments.

Decision-making, sensitivity to reward and attrition in weight management.

Objective: Attrition is a common problem in weight management. Understanding the risk factors for attrition should enhance professionals' ability to increase completion rates and improve health outcomes for more individuals. A model that draws upon neuropsychological knowledge on reward-sensitivity in obesity and overeating to predict attrition is proposed.

Antithrombin therapy in pancreas retransplantation and pancreas-after-kidney/pancreas-transplantation-alone patients.

Antithrombin (AT) is a coagulatory inhibitor with pleiotropic activities. AT reduces ischemia/reperfusion injury and has been successfully used in patients with simultaneous pancreas kidney transplantation. This study retrospectively analyzes prophylactic high-dose AT application in patients with solitary pancreas transplantation traditionally related to suboptimal results.

Comparison of glucose and lipid metabolism and bone mineralization in patients with growth hormone deficiency with and without long-term growth hormone replacement.

The effects of long-term growth hormone (GH) substitution in pituitary-insufficient patients with GH deficiency (GHD-pats) on glucose and lipid metabolism and bone mineral density (BMD) have yet to be ascertained. We performed this cross-sectional study comparing GHD-pats with and without long-term GH substitution. We measured lipid parameters at baseline and glucose and insulin concentrations for 3 hours during oral glucose tolerance test in 52 GHD-pats (21 female and 31 male; median age, 51.

Validation of the International Classification of Functioning, Disability and Health (ICF) core set for diabetes mellitus from the patient perspective using focus groups.

Aims: The Comprehensive ICF Core Set for diabetes mellitus (DM) is a specific application of the International Classification of Functioning, Disability and Health (ICF) of the World Health Organization for clinical and research purposes involving the disorder. It represents the typical spectrum of functional problems in patients with DM. The objective of the study was to validate the Comprehensive ICF Core Set for DM from the perspective of patients.

Intrarenal resistance index for the assessment of early renal function impairment in patients with liver cirrhosis.

Background: Renovascular vasoconstriction in patients with hepatorenal syndrome can be quantified by the renal arterial resistance index (RI). We investigated the value of RI measurement in detection of renal function impairment in patients with different stages of chronic liver disease.

Methods: Subjects were divided into 4 groups containing 21 patients with liver cirrhosis and ascites, 25 patients with liver cirrhosis without ascites, 35 patients with fatty liver disease and 78 control subjects.

Prevalence of cholecystolithiasis and its management among kidney/pancreas-transplanted type 1 (insulin-dependent) diabetic patients.

Background: Simultaneous pancreas/kidney transplantation (SPK) should be the procedure of choice for (pre)uremic patients with type 1 diabetes. All standard immunosuppressive protocols for SPK include a calcineurin-inhibitor. Both calcineurin inhibitors, cyclosporine (CyA) and probably tacrolimus (FK506) too, are associated with the occurrence of cholelithiasis due to their metabolic side effects.

Impaired glucose tolerance in pancreas grafted diabetic patients is due to insulin secretory defects.

Introduction: Pancreas transplantation in diabetic patients can sustain insulin independence for years. The aim of the study was to measure the incidence of an impaired or diabetic glucose tolerance in patients after successful transplantation and analyse insulin resistance and insulin secretion.

Methods: 174 Type 1 diabetic recipients of simultaneous pancreas/kidney (SPK) transplants were investigated early (three months) and 95 patients late (five years) after transplantation using an oral glucose tolerance test combined with an iv arginine load.

Age dependency of intrarenal resistance index (RI) in healthy adults and patients with fatty liver disease.

Background: Our aim was to investigate the influence of age and gender on intrarenal resistance index (RI) measurements in 78 healthy subjects (46 males, 32 females; group 1) and 35 subjects (group 2) with fatty liver disease (28 males and 7 females).

Subjects And Methods: First, each subject underwent a conventional abdominal ultrasound examination. Then, intrarenal RI values were determined from three distinct interlobar and cortical arteries respectively on both kidneys.

Metabolic follow-up after long-term pancreas graft survival.

Design: Successful pancreas transplantation results in insulin independence and normoglycemia. This prospective study was performed to investigate long-term metabolic changes after pancreas transplantation.

Methods: Thirty-eight type 1 diabetic patients after simultaneous pancreas/kidney transplantation (SPK) with a pancreas graft survival for at least 10 years were studied in a prospective manner.

Alcohol administration acutely inhibits ghrelin secretion in an experiment involving psychosocial stress.

The appetite-regulating hormones leptin and ghrelin are altered in alcoholism and influence the hypothalamic-pituitary-adrenal system. We investigated whether acute ethanol ingestion and stress exposure affect ghrelin secretion. Nine healthy male volunteers were exposed to a standardized laboratory stressor involving public speaking on 2 days.

Pulmonary function in patients with type 1 diabetes before and after simultaneous pancreas and kidney transplantation.

Introduction: Pulmonary function is impaired in type 1 diabetes mellitus and is associated with the quality of metabolic control. Correction of chronic hyperglycemia by pancreas transplantation may ameliorate pulmonary function.

Methods: Lung volume and diffusing capacity were measured in 75 uremic patients with type 1 diabetes and a long diabetes duration waiting for a simultaneous kidney and pancreas transplantation (SPK).

Effects of the long-acting somatostatin analogue Lanreotide Autogel on glucose tolerance and insulin resistance in acromegaly.

Object: Treatment with somatostatin analogues (SA) not only inhibits GH secretion but may also impair insulin secretion. In order to evaluate the influence of SA on glucose metabolism, we investigated insulin resistance (IR) and beta-cell function, using the recommended combination of homeostatic model assessment of IR (HOMA-IR) and beta-cell function (HOMA-beta).

Design And Methods: This is a prospective, cross-sectional study.

Single-shot antithrombin in human pancreas-kidney transplantation: reduction of reperfusion pancreatitis and prevention of graft thrombosis.

Reperfusion pancreatitis and graft thrombosis often induce early graft loss in simultaneous pancreas-kidney (SPK) transplantation. Antithrombin (AT) is a coagulatory inhibitor with pleiotropic activities that reduces experimental ischemia/reperfusion injury. This study retrospectively analyses prophylactic high-dose AT application in patients with first SPK.

[(Auto)immunological aspects of type 1 diabetes mellitus].

Today, the autoimmunogenesis of type 1 diabetes mellitus is unquestioned. Evidence for this includes the detection of specific antibodies, an association with other autoimmune diseases, and the possibilities of immunological interventions. The actual trigger that leads to the loss of immunotolerance has not so far been identified.

[Therapy of diabetes mellitus. Pancreas transplantation, islet transplantation, stem cell and gene therapy].

The long-term normalization of glucose metabolism - a prerequisite for the prevention of secondary complications in patients with diabetes mellitus - is only possible by transplantation of a whole pancreas or a reasonable number of islets. An absolute indication for pancreas grafting is given in type 1 diabetic patients with end-stage renal disease. The 1-year survival after simultaneous kidney/pancreas transplantation is, according to the international registry, 94-100% for patients, 89-92% for kidneys and 85-87% for the pancreas.

[Comorbidities and complications of adiposis].

Overweight and obesity are associated with a high number of complications and co-morbidities. Obesity can affect almost all tissues and organs of the body. Obesity is associated with the components of the metabolic syndrome and is the leading cause of type 2 diabetes.

Insulin and islet autoantibodies after pancreas transplantation.

Autoimmune recurrence and subsequent diabetes after pancreas transplantation has been described. In this cross-sectional study 91 type 1 diabetic patients were examined after successful pancreas/kidney transplantation (SPK). We studied the prevalence of autoantibodies to insulin (IAA), glutamate decarboxylase (GAD) and tyrosine phosphatase (IA-2) as well as parameters of pancreas graft function.

Simultaneous pancreas-kidney transplantation: analysis of rejection.

Unlabelled: The 3-year data concerning the occurrence of rejection episodes (RE) are reported herein.

Patients And Methods: Two hundred five simultaneous pancreas-kidney (SPK) transplantations were performed from May 1998 to September 2000, including 103 patients randomly assigned to tacrolimus (Tac) and 102 to cyclosporine microemulsion (CsA-ME). All patients received concomitant rATG induction therapy, mycophenolate mofetil (MMF), and short-term corticosteroids.

Rejection after simultaneous pancreas-kidney transplantation.

Background: Simultaneous pancreas-kidney (SPK) transplantation is an accepted therapy for type 1 diabetic patients with end-stage renal disease. This study analyses the occurrence of rejection episodes in patients undergoing SPK.

Methods: The study population was obtained from 205 patients enrolled in the Euro-SPK 001 study and randomized to receive tacrolimus- (n = 103) or cyclosporin microemulsion (ME)-based (n = 102) immunosuppressive therapy.

Four-year follow-up of acromegalic patients treated with the new long-acting formulation of Lanreotide (Lanreotide Autogel).

Lanreotide Autogel (Ipsen) is a long-acting somatostatin analogue (SA) in a new galenic formulation suitable for subcutaneous (s.c.) injection.

Glucose metabolism after pancreas transplantation: cyclosporine versus tacrolimus.

Background: The results of the new immunosuppressants in simultaneous pancreas-kidney transplantation (SPK) concerning organ survival and rejection rates are excellent. Tacrolimus as well as cyclosporine are assumed to be diabetogenic; however, there are no comparative studies investigating their effects on glucose metabolism.

Methods: One hundred thirty-six type 1 diabetic patients who had undergone successful SPK were investigated.

Detection of isolated tumor cells by polymerase chain reaction-restriction fragment length polymorphism for K-ras mutations in tissue samples of 199 colorectal cancer patients.

The aim of this study was to identify K-ras mutations as marker for isolated tumor cells in liver, lymph node, and bone marrow specimens of colorectal cancer patients. To detect these, a PCR-RFLP assay was used with a sensitivity exceeding that of routine histopathology by at least 1 order of magnitude. In addition, the ratio of mutated versus wild-type alleles was determined by an internal standard.

Improved ultrasound examination of pancreas grafts in type 1 (insulin-dependent) diabetic patients using tissue harmonic imaging.

Background: Combined kidney/pancreas transplantation is an established therapy for type 1 diabetic patients with end-stage renal disease. Ultrasound examinations are valuable noninvasive methods for postoperative monitoring of transplant recipients. Kidney grafts are easily to detect, whereas pancreas grafts are surrounded or covered by small bowel loops, which makes the examination much more difficult.
