Juvenile neuronal ceroid lipofuscinosis, linked to mutations in the ceroid lipofuscinosis, neuronal 3 (CLN3) gene, is a childhood-onset neurodegenerative disorder. Although mood and behavioral symptoms are described in this group, it's unclear whether these meet diagnostic criteria. We investigated the occurrence of neurodevelopmental and psychiatric disorders in a nationally representative sample, using a semistructured psychiatric interview, as well as the use of psychotropic medication. Ten of 20 individuals met the criteria for one or more current diagnoses, with an additional 5 having past diagnoses, resulting in a lifetime occurrence in 15 individuals. Anxiety disorders were the most frequent diagnostic group, followed by neurodevelopmental disorders. Attention-deficit hyperactivity disorder was the most common single diagnosis. Subthreshold psychiatric symptoms were present in all individuals. Although psychiatric disorders were frequent, few used psychotropic medication. These findings underscore the need for routine monitoring of neurodevelopmental and psychiatric disorders in individuals with CLN3 and the provision of evidence-based treatments. Show less

We aimed to investigate the potential associations between serum apolipoprotein levels in early pregnancy and the risk of gestational diabetes mellitus (GDM) and adverse pregnancy outcomes. This was an observational study of the population-based Odense Child Cohort. Pregnant women were followed from inclusion until childbirth. Apolipoprotein levels, including 12 apolipoproteins (ApoA-I, ApoA-II, ApoA-IV, ApoB, ApoC-I, ApoC-II, ApoC-III, ApoD, ApoE, ApoH, ApoJ, and ApoM) were measured by targeted proteomics using liquid chromatography mass spectrometry on late first trimester serum samples stored in a biobank. GDM was defined by WHO 2013 diagnostic criteria. A total of 991 pregnant women were included, of which 415 (41.9%) were diagnosed with GDM. GDM was associated with increasing ApoB (adjusted odds ratio [OR]: 1.26, P = .002) and ApoD levels (adjusted OR: 0.84, P = .021). ApoB levels in early pregnancy correlated significantly and positively with insulin resistance (r = 0.22, P < .001) and beta-cell function in third trimester (r = 0.20, P < .001), whereas early pregnancy ApoD levels were inversely correlated with insulin resistance (r = -0.14, P < .001) and beta-cell function (r = -0.12, P < .001). Finally, high levels of ApoD was significantly associated with lower risk of large-for-gestational-age infants (adjusted OR: 0.78, P = .041). High levels of ApoB and low levels of ApoD in early pregnancy were independently associated with an increased risk of GDM, insulin resistance, and large-for-gestational-age infants (low ApoD only), suggesting potential roles for future management of pregnancy outcomes.

Bilberries and blackcurrants are nutrient sources rich in bioactive components, including dietary fibers, polyphenols, and anthocyanins, which possess potent cardiovascular protective properties. Few studies investigating the cardio-protective effects of natural components have focused on whole bilberries or blackcurrants. The aim of this trial was to investigate whether a diet enriched with bilberries or blackcurrants has beneficial effects on glucose metabolism, lipid profile, blood pressure, and expression of genes related to glucose and lipid metabolism. Male Zucker Diabetic Fatty (ZDF) rats (n = 48) were randomly assigned to either a control, bilberry-enriched, blackcurrant-enriched, or fiber-enriched diet for 8 weeks ad libitum. Real-time quantitative PCR analysis was performed on liver, adipose, and muscle tissue. Berry polyphenol content was determined by HPLC and LC-MS analysis. Bilberry enrichment reduced total (-21%, p = 0.0132) and LDL-cholesterol (-60%, p = 0.0229) levels, but increased HDL-cholesterol to a lesser extent than in controls. This may partly be due to the altered hepatic liver X receptor-α expression (-24%, p < 0.001). Neither bilberries nor blackcurrants influenced glucose metabolism or blood pressure. Nevertheless, transcriptional analysis implied a better conservation of hepatic and adipocyte insulin sensitivity by bilberry enrichment. Anthocyanins constituted 91% and 87% of total polyphenol content in bilberries and blackcurrants, respectively. However, total anthocyanin content (3441 mg/100 g) was 4-fold higher in bilberries than in blackcurrants (871 mg/100 g). Bilberry consumption ameliorated total and LDL-cholesterol levels, but not HDL-cholesterol levels in ZDF rats. Neither bilberry nor blackcurrant enrichment delayed the development of diabetes or hypertension. Thus, in rats, bilberries may be valuable as a dietary preventive agent against hypercholesterolemia, probably by virtue of their high anthocyanin content. Show less
