  Background Vast amounts of data show associations between maternal obesity, dysglycemia, diabetes, and undernutrition during pregnancy and increased cardiovascular disease risk in offspring. However, elevated maternal LDL cholesterol (LDL-C) in pregnancy and offspring cardiovascular disease (CVD) risk has scarcely been studied. Objective Our objective was to investigate the associations between elevated maternal LDL-C in pregnancy and CVD risk factors in 6-to-13-year-old offspring. Methods We recruited 6-to-13-year-old children whose mothers attended a pregnancy cohort and who had high or low cholesterol in pregnancy, defined as LDL-C over the 90th percentile or below the 10th percentile within the pregnancy cohort, respectively. We measured CVD risk factors in the children in the 2 groups. Results Maternal plasma LDL-C at gestational week 14 to 16 was 4.0 and 1.4 mmol/L in the hypercholesterolemic (n = 27) and hypocholesterolemic (n = 34) groups, respectively (P < .001). Interestingly, offspring plasma LDL-C was 0.4 mmol/L higher in children whose mothers had hypercholesterolemia during pregnancy (P < .01). We found no difference in birthweight or any other clinical or biochemical CVD risk factors or dietary intake between the children at 6–13 years. Conclusions Women with elevated LDL-C during early pregnancy have offspring with higher LDL-C already at the age of 6–13 years. Unless cholesterol-reducing measures are successfully implemented, the affected children may be at increased cardiovascular risk.

  The aim of this commentary is to balance the pros and cons for pre-surgical SSA treatment in a modern perspective ending up with a pragmatic recommendation for treatment based on the current evidence and expertise of the authors. Even though prospective and randomized studies in this particular area are hampered by obvious limitations, the interpretation of the four published trials has in general been in favor of pre-treatment with SSA, showing a better outcome following surgery. However, major drawbacks of these studies, such as non-optimal diagnostic criteria for cure, potential selection bias, and timing of the postoperative evaluation in SSA pre-treated patients, limit their overall interpretation. Three matched-controlled studies showed remarkably similar results with no apparent beneficial effect of SSA pre-treatment on surgical outcome. Both prospective, randomized studies and retrospective studies did not find any significant difference in the rate of endocrine and non-endocrine complications related to surgery, despite the beneficial clinical effects of SSA treatment in most acromegalic patients. The newly diagnosed patient with acromegaly should be carefully evaluated in the trans-disciplinary neuroendocrine team and treatment individualized accordingly. The issue of SSA pre-treatment to improve surgical outcome is yet to be settled and further methodologically sound studies are probably necessary to clarify this point.

  OBJECTIVES: Somatotroph adenomas secrete supraphysiological amounts of GH, causing acromegaly. We have previously shown epithelial splicing regulator 1 (ESRP1) to play a role in epithelial mesenchymal transition (EMT) progression in these adenomas and account for poor treatment response. We evaluated if the mRNA levels of the GH/CSH gene cluster in somatotroph adenomas are associated with an epithelial phenotype and response to SA treatment. METHODS: We investigated the associations between ESRP1 and the growth hormone/chorionic somatomammotropin (GH/CSH) gene cluster by RNA sequencing (RNAseq). CSH2 isoform 3 mRNA was further evaluated in 65 somatotroph adenomas and associations with disease severity and treatment response. RESULTS: mRNA for all genes in the GH/CSH cluster were expressed, however, only chorionic somatomammotropin 2/placental lactogen 2 (CSH2) displayed an alternative splicing pattern. CSH2 isoform 3 was associated with a dense granulation pattern and an epithelial phenotype with high levels of ESRP1 and E-cadherin expression. Further, CSH2 isoform 3 was associated with reduced serum GH and IGF-I levels after somatostatin analog treatment. CONCLUSIONS: Attenuated CSH2 isoform 3 was associated with mesenchymal phenotype and a blunted clinical response to somatostatin analog treatment in patients with acromegaly.

  Background: Cushing’s disease is an ACTH-producing pituitary adenoma, and the primary treatment is microscopic or endoscopic transsphenoidal selective adenectomy. The aims of the present study were to evaluate whether the early postoperative S-cortisol level can serve as a prognostic marker for short- and long-term remission, and retrospectively review our own short and long term results after surgery for Cushing’s disease. Methods: This single centre, retrospective study consists of 19 consecutive patients with Cushing’s disease who underwent transsphenoidal surgery. S-cortisol was measured every 6 h after the operation without any glucocorticoid replacement. We have follow-up on all patients, with a mean follow-up of 68 months. Results: At the three-month follow-up, 16 patients (84 %) were in remission; at 12 months, 18 (95 %) were in remission and at the final follow-up (mean 68 months), 13 (68 %) were in remission. Five-years recurrence rate was 26 %. The mean postoperative S-cortisol nadir was significantly lower in the group of patients in remission than in the non-remission group at 3 months, but there was no difference between those in long-term remission compared to those in long-term non-remission. The optimal cut-off value for classifying 3-month remission was 74 nmol/l. Conclusion: We achieved a 95 % 1-year remission rate with transsphenoidal surgery for Cushing’s disease in this series of consecutive patients. However, the 5-year recurrence rate was 26 %, showing the need for regular clinical and biochemical controls in this patient group. The mean postoperative serum-cortisol nadir was significantly lower in patients in remission at 3 months compared to patients not in remission at 3 months, but a low postoperative S-cortisol did not predict long-term remission.

  The purposes of this study were to assess the prevalence of chronic fatigue (CF) in irradiated survivors of non-Hodgkin lymphoma, analyze for associations between hormonal dysfunction and CF, and to investigate the associations between CF and functioning. Invited survivors were all treated with radiation to the head and neck region, with or without additional chemotherapy. The participants (n =98) responded to questionnaires measuring CF, mental distress (HADS), and functioning (SF-36), and had blood drawn for analyses of four hormonal axes. Hormonal status was categorized as normal, hormone dysfunction in one or more axes, or hormone replacement therapy. A total of 29% of the survivors had CF. In multivariate analyses there was an increased risk of CF among survivors with untreated hormone dysfunction (OR 3.87, 95% CI: 1.20–12.51, P 0.02). Survivors on hormone substitution did not have increased risk for CF compared to survivors with normal hormonal status. CF was significantly associated with reduced functioning.

  Background: Patients suffering a distal radial fracture have a high prevalence of osteoporosis [1]. Ankle fractures have traditionally not been considered to be an osteoporotic fracture, however more recent studies suggest otherwise [2, 3]. Patients with celiac disease (CD) have low bone mineral bone density (BMD), and overall findings indicate an increased risk of fracture [4, 5]. Objectives: To investigate and compare the prevalence of osteoporosis in patients with acute distal radius or ankle fracture and describe risk factors for osteoporosis in the two groups. Methods: 400 consecutive patients over the age of 40 with acute distal radius or ankle fracture were included in this study after referral from the orthopedic department at Forde General Hospital, Norway. BMD of the hips and spine was measured and history of previous fracture, comorbidities, medication, physical activity, smoking habits, body mass index (BMI) and nutritional factors were registered. Serum analysis to detect secondary osteoporosis including IgA tissue transglutaminase was performed. Results: The prevalence of osteoporosis was 44.7 % in the patients with distal radius fracture (n=293) compared to 23.4 % in the ankle fracture group (n=107). Significant risk factors for having osteoporosis when having suffered a distal radius fracture were older age, female gender, lower BMI, and celiac disease (defined as either known celiac disease AND/OR positive IgA tissue transglutaminase). Elevated PTH or low vitamin D was not significant. The patients with radius fracture and osteoporosis had a higher prevalence of celiac disease (7.6%) than the ones with radius fracture and osteopenia or normal BMD (0.6%). In the ankle fracture patients with osteoporosis there were no celiac disease cases, versus 3.7% in the ankle fracture patients with osteopenia/normal BMD. In the ankle fracture group, low BMI was a significant risk factor for being osteoporotic, but no other significant risk factors were found. Conclusions: The prevalence of osteoporosis was higher among persons suffering a distal radius fracture than among those with acute ankle fracture. Several well-known risk factors for osteoporosis were associated with being osteoporotic among subjects suffering a distal radius fracture, but only BMI was associated with osteoporosis in the ankle fracture group.
