- Sleep loss and insufficient sleep are risk factors for cardiometabolic diseases, but data on how insufficient sleep contributes to these diseases are scarce. These questions were addressed using two approaches: an experimental, partial sleep restriction study (14 cases and 7 control subjects) with objective verification of sleep amount, and two independent epidemiological cohorts (altogether 2739 individuals) with questions of sleep insufficiency. In both approaches, blood transcriptome and serum metabolome were analysed. Sleep loss decreased the expression of genes encoding cholesterol transporters and increased expression in pathways involved in inflammatory responses in both paradigms. Metabolomic analyses revealed lower circulating large HDL in the population cohorts among subjects reporting insufficient sleep, while circulating LDL decreased in the experimental sleep restriction study. These findings suggest that prolonged sleep deprivation modifies inflammatory and cholesterol pathways at the level of gene expression and serum lipoproteins, inducing changes toward potentially higher risk for cardiometabolic diseases.

- Introduction: Calcium has a pivotal role in haemostasis. We investigated the association of baseline calcium levels with admission intracerebral haemorrhage (ICH) volume. Methods: This is a retrospective analysis of consecutive ICH patients in an academic hospital between January 2005 and March 2010. Computed tomography (CT) of the brain and serum/plasma ionized calcium had to be taken within 72 h of symptom onset and within 12 h of each other in order to fulfil the study criteria. ICH cases related to trauma or tumour as well as sole intraventricular haemorrhages were excluded. Baseline haematoma volumes were calculated using semiautomated planimetry. The hypocalcaemic (Ca-ion <1.16 mmol/L) and normocalcaemic (1.16–1.30 mmol/L) patient groups were compared in univariate analyses. Association between admission hypocalcaemia and haematoma volume was studied using multivariable regression models. Results: Out of 1013 consecutive patients, 447 fulfilled the study criteria. Hypocalcaemic patients (n = 178; 39.8%) had larger baseline hematoma volumes (median 30.2 mL, IQR 11.4–58.7 mL), compared to normocalcaemic patients (n = 255; 57.0%; median 16.8 mL, IQR 7.4–44.2 mL). The median ICH volume among hypercalcaemic patients (n = 14; 3.1% of included patients) was 6.5 mL (IQR 3.1–34.6 mL). On linear regression, admission hypocalcaemia was independently associated with larger hematoma volumes (β = 11.77; 95% CI 4.66–18.87, P = 0.01). Patients with larger haematoma volumes had higher mortality. Conclusion: Hypocalcaemia is associated with larger admission haematoma volumes among ICH patients. Higher mortality among hypocalcaemic patients is very likely mediated through larger ICH volumes. © 2019 Elsevier B.V.

- Background: Malignant potential of small (<= 20 mm) nonfunctional pancreatic neuroendocrine tumors (sNF-PNET) is difficult to predict and management remain controversial. The aim of this study was to assess the prognosis of sporadic nonmetastatic sNF-PNETs.Methods: Patients were identified from databases of 16 centers. Outcomes and risk factors for recurrence were identified by uni-and multivariate analyses.Results: sNF-PNET was resected in 210 patients, and 66% (n = 138) were asymptomatic. Median age was 60 years, median tumor size was 15 mm, parenchyma-sparing surgery was performed in 42%. Postoperative mortality was 0.5% (n = 1), severe morbidity rate was 14.3% (n = 30), and 14 of 132 patients (10.6%) with harvested lymph nodes had metastatic lymph nodes. Tumor size, presence of biliary or pancreatic duct dilatation, and WHO grade 2-3 were independently associated with recurrence. Patients with tumors sized <= 10 mm were disease free at last follow-up. The 1-, 3- and 5-year disease-free survival rates for patients with tumors sized 11-20 mm on preoperative imaging were 95.1%, 91.0%, and 87.3%, respectively.Conclusions: In sNF-PNETs, the presence of biliary or pancreatic duct dilatation or WHO grade 2-3 advocate for surgical treatment. In the remaining patients, a wait-and-see policy might be considered.
