Background: Maternal obesity is associated with adverse outcome for pregnancy and childbirths. While bariatric surgery may improve fertility and reduce the risk of certain pregnancy-related complications such as hypertension and gestational diabetes mellitus, there is a lack of evidence on the optimal nutritional monitoring and supplementation strategies in pregnancy following bariatric surgery. We aimed to assess the impact of bariatric surgery on micronutrients in post-bariatric pregnancy and possible differences between gastric bypass surgery and sleeve gastrectomy.

Background: N-methyladenosine (m6A) is one of the most abundant post-transcriptional modifications on mRNA influencing mRNA metabolism. There is emerging evidence for its implication in metabolic disease. No comprehensive analyses on gene expression of m6A regulators in human adipose tissue, especially in paired adipose tissue depots, and its correlation with clinical variables were reported so far.

Serglycin is a proteoglycan highly expressed by various immune cell types known to infiltrate adipose tissue under obese conditions. To investigate if serglycin expression has an impact on diet-induced adipose tissue inflammation, we subjected and mice (C57BL/6J genetic background) to an 8-wk high-fat and high-sucrose diet.

Significant childhood adversity and chronic life stress are highly prevalent in patients with severe obesity. Such stress has been found to increase risk of adulthood obesity by up to 50%, and it can also substantially degrade the effectiveness of evidence-based treatments for this chronic disease condition. Despite general appreciation of these facts, though, stress is not frequently measured in obesity research or routinely assessed during treatment for obesity or obesity-related complications.

Introduction: Bariatric surgery is increasingly recognised as an effective treatment option for subjects with type 2 diabetes and obesity; however, there is no conclusive evidence on the superiority of Roux-en-Y gastric bypass or sleeve gastrectomy. The Oseberg study was designed to compare the effects of gastric bypass and sleeve gastrectomy on remission of type 2 diabetes and β-cell function.
Methods And Analysis: Single-centre, randomised, triple-blinded, two-armed superiority trial carried out at the Morbid Obesity Centre at Vestfold Hospital Trust in Norway.
Background: Bariatric surgery is associated with greater and more sustainable weight loss compared with lifestyle intervention programs. On the other hand, bariatric surgery may also be associated with physical and psychosocial complications. The influence of psychological evaluation on treatment choice, however, is not known.

Aim: To assess the prevalence of undiagnosed DM2 and compare the performance of glycated A1c (HbA1c) and fasting glucose (FG) for the diagnosis of DM2 and prediabetes (preDM) in patients with morbid obesity.
Patients And Methods: We measured fasting glucose and HbA1c in 537 consecutive patients with morbid obesity without previously known DM2.
Background: The King's Obesity Staging Criteria (KOSC) comprises of a four-graded set of health related domains. We aimed to examine whether, according to KOSC, patients undergoing bariatric surgery differed from those opting for conservative treatment.
Methods: We graded 2142 consecutive patients with morbid obesity attending our centre from 2005-10 into the following KOSC domains: airway/apnoea, body mass index (BMI), cardiovascular risk (CV-risk), diabetes mellitus, economic complications, functional limitations, gonadal dysfunction, and perceived health status/body image.
Background: The association of early-onset posttransplantation hyperglycemia with long-term renal allograft survival is unknown.
Methods: Seventy-one (SD 9) days after transplantation, 1410 first-time kidney transplant recipients without diabetes underwent an oral glucose tolerance test and were observed until primary outcome (graft loss) or December 31, 2008 (median [range], 6.0 years [0.
Background And Objectives: Guidelines recommend that candidates for kidney transplantation (KTx) who do not have diabetes perform a pretransplantation oral glucose tolerance test (OGTT) when fasting plasma glucose (FPG) is <110 mg/dl (<6.1 mmol/L); however, the OGTT is potentially costly and cumbersome. We studied the role of the OGTT for diagnosing diabetes and the accuracy of FPG and glycated hemoglobin (HbA(1c)) for predicting a diabetic OGTT before KTx.

Suppression of regulatory T lymphocytes may have a negative impact on pancreatic beta-cells. Induction with basiliximab affects regulatory T-cell function and may therefore, theoretically, also affect glucose homeostasis in renal transplant recipients.
View Article and Find Full Text PDFBackground: Renal insufficiency predisposes to insulin resistance, hyperparathyroidism and derangements in calcium phosphate and nitrogenous compound balance, leading to pre-transplant hyperglycaemia. These metabolic risk factors are not fully corrected after renal transplantation. The present study aimed to assess the role of pre-transplant glycaemia and the named metabolic risk factors in post-transplant hyperglycaemia [PHYG; impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or diabetes mellitus (DM)].
View Article and Find Full Text PDFBackground: Fasting plasma glucose (fPG) is recommended to identify new-onset posttransplant diabetes mellitus (PTDM), but an oral glucose tolerance test (OGTT) has higher diagnostic sensitivity. We aimed to assess the accuracy of fPG and glycosylated hemoglobin (HbA1c) for the selection of patients who should undergo a diagnostic OGTT 10 weeks after renal transplantation.
Methods: A total of 1571 renal transplant recipients without prior diabetes underwent an OGTT 10 weeks after transplantation.
Background: A previous study (1995-1996) of 173 nondiabetic renal transplant recipients (historical cohort; HC) revealed a 20% incidence of new-onset posttransplantation diabetes mellitus (PTDM) and 32% with impaired glucose tolerance (IGT) or impaired fasting glucose (IFG). We examined whether glucose tolerance has improved after recent changes in our immunosuppressive protocol and a switch from deferred to preemptive cytomegalovirus (CMV) therapy.
Methods: A total of 321 consecutive, nondiabetic patients (new cohort; NC) were examined 10 weeks after kidney transplantation with an oral glucose tolerance test (n=301) between January 2004 and December 2005.
