  Dopamine and noradrenaline are functionally connected to delirium and have been targets for pharmacological interventions but the biochemical evidence to support this notion is limited. To study the CSF levels of dopamine, noradrenaline and the third catecholamine adrenaline in delirium and dementia, these were quantified in three patient cohorts: (i) cognitively normal elderly patients (n¼122); (ii) hip fracture patients with or without delirium and dementia (n¼118); and (iii) patients with delirium precipitated by another medical condition (medical delirium, n¼26). Delirium was assessed by the Confusion Assessment Method. The hip fracture cohort had higher CSF levels of noradrenaline and adrenaline than the two other cohorts (both P<0.001). Within the hip fracture cohort those with delirium (n¼65) had lower CSF adrenaline and dopamine levels than those without delirium (n¼52, P¼0.03, P¼0.002). Similarly, the medical delirium patients had lower CSF dopamine levels than the cognitively normal elderly (P<0.001). Age did not correlate with the CSF catecholamine levels. These findings with lower CSF dopamine levels in hip fracture- and medical delirium patients challenge the theory of dopamine excess in delirium and question use of antipsychotics in delirium. The use of alpha-2 agonists with the potential to reduce noradrenaline release needs further examination.

  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.

  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.
