randomised trial of continuous skin-to-skin contact after preterm birth and the effects on salivary cortisol, parental stress, depression, and breastfeeding, 2015, Early Human Development, (91) Ainsworth's sensitivity scale was used to control for parental sensitivity.Subjects: Thirty-seven families from two different neonatal care units in Sweden, randomised to either almost continuous SSC or standard care (SC).Results: Infants randomised to SSC had a lower salivary cortisol reactivity at one month (p=0.01). There was a correlation between the mothers' and the preterm infants' salivary cortisol levels at four months in the SSC group (ρ=0.65, p=0.005), but not in the SC group (ρ=0.14, p=0.63). Fathers in SSC scored lower on the SPSQ sub-scale spouse relationship problems compared to fathers in SC (p<0.05).Conclusions: Almost continuous SSC decreases infants' cortisol reactivity in response to handling, improves the concordance between mothers' and infants' salivary cortisol levels, and decreases fathers' experiences of spouse relationship problems.

Background: In Sweden, FreeStyle Libre a flash glucose monitoring system came onto the market in 2014 as a complement to self-monitoring of blood glucose. The aim of this study was to evaluate the accuracy and treatment experience of the FreeStyle Libre system.Methods: Fifty-eight adults with type 1 diabetes used FreeStyle Libre for 10–14 days and measured capillary blood glucose levels with the HemoCue blood glucose measurement system at least six times a day simultaneously.Results: For the entire study period, the mean absolute relative difference (MARD) was 13.2% (95% confidence interval [CI] 12.0%–14.4%). MARD was 13.6% (95% CI 12.1%–15.4%) during week 1 and 12.7% (95% CI 11.5%–13.9%) during week 2. The mean absolute difference (MAD) for the whole study period was 19.8 mg/dL (1.1 mmol/L) (95% CI 17.8–21.8 mg/dL), including 20.5 mg/dL (1.14 mmol/L) during week 1 and 19.0 mg/dL (1.05 mmol/L) during week 2. The overall correlation coefficient was 0.96. For glucose values <72, 72–180, and >180 mg/dL (<4, 4–10, and >10 mmol/L), the MARD was 20.3% (95% CI 17.7%–23.1%), 14.7% (95% CI 13.4%–16%), and 9.6% (95% CI 8.5%–10.8%), respectively, and respective MAD values were 12.3, 17.8, and 23.6 mg/dL (0.69, 0.99, and 1.31 mmol/L). Using the 10-item visual analog scale, patients rated their experience with FreeStyle Libre as generally positive, with mean values ranging from 8.22 to 9.8.Conclusions: FreeStyle Libre had a similar overall MARD as continuous blood glucose monitoring systems in earlier studies when studied in similar at-home conditions. The overall patient satisfaction was high.

In multiple endocrine neoplasia type 1 (MEN-1), benign enlargement of the adrenal cortex has been found in about one third of necropsy cases. To elucidate the clinical and genetic characteristics of the MEN-1 adrenal lesion, we have investigated 33 MEN-1 patients. Twelve individuals (37%) demonstrated adrenal enlargement, which was bilateral in 7 of them. Histopathology revealed diffuse and nodular cortical hyperplasia, adenomas, and a single case of adrenocortical carcinoma. The apparently benign adrenal enlargements were not associated with presently ascertainable biochemical disturbances in the hypothalamic-pituitary-adrenocortical axis, and they were without radiological signs of progression during follow-up. The individual developing unilateral adrenocortical carcinoma showed rapid adrenal expansion, feminization, and an abnormal urinary steroid profile after 4 yr of observation for bilateral minor adrenal enlargements. Pancreatic endocrine tumors were significantly overrepresented and present in all MEN-1 individuals with adrenal involvement. In agreement with findings in sporadic cases, the MEN-1 adrenocortical carcinoma genome showed loss of constitutional heterozygosity for alleles at 17p, 13q, 11p, and 11q. The benign adrenal lesions retained heterozygosity for the MEN-1 locus at chromosome 11 q 13. Despite its prevalence and malignant potential, the pituitary-independent adrenocortical proliferation does not appear to be a primary lesion in MEN-1, but might represent a secondary phenomenon, perhaps related to the pancreatic endocrine tumor.

OBJECTIVE: Some studies have shown a more rapid gastric emptying in obese subjects. Six to twelve months after jejunoileal bypass (JIB) neurotensin (NT) and enteroglucagon have been shown to be elevated after food intake. These hormones, together with peptide YY (PYY) and glucagon-like peptide-1 (GLP-1) have been implicated in the reduction of upper gastrointestinal motility seen after infusion of nutrients into the ileum. AIM: To study if the postprandial gut hormone pattern and gastric emptying is altered 20 y after JIB. SUBJECTS: Seven subjects operated with JIB a mean (s.d.) 20 AE 3 y ago, with a BMI of 44 AE 4 kg/m 2 at the time of surgery and 31 AE 4 at present. For comparison seven sex-matched non-operated obese controls (BMI 43 AE 3) were studied. METHODS: Serial blood samples were obtained every 10 min after intake of a 280 kcal meal. Radioimmunoassays for motilin, cholecystokinin (CCK), NT, PYY and GLP-1 were performed. Gastric emptying of a solid meal was studied using a radioactively labelled omelette (of 310 kcal) for 120 min). RESULTS: After JIB postprandial motilin, CCK, NT, PYY and GLP-1 were elevated compared to non-operated obese subjects. Similarly, basal levels of CCK, motilin, GLP-1 and PYY were elevated in the operated group. No difference was observed in the rate of gastric emptying between the two groups. CONCLUSION: Both fasting and postprandial gut hormone levels are elevated 20 y after JIB. The impact of long-term rapid stimulation of the ileum and subsequent raised gut hormone levels on gastric emptying is not clear.

This study reveals, for the first time, an interspecific synchronization in long-term stress levels. Previously, acute stress, has been shown to be highly contagious both among humans and between individuals of other species. Here, long-term stress synchronization in dogs and their owners was investigated. We studied 58 dog-human dyads and analyzed their hair cortisol concentrations (HCC) at two separate occasions, reflecting levels during previous summer and winter months. The personality traits of both dogs and their owners were determined through owner-completed Dog Personality Questionnaire (DPQ) and human Big Five Inventory (BFI) surveys. In addition, the dogs’ activity levels were continuously monitored with a remote cloud-based activity collar for one week. Shetland sheepdogs (N = 33) and border collies (N = 25), balanced for sex, participated, and both pet dogs and actively competing dogs (agility and obedience) were included to represent different lifestyles. The results showed significant interspecies correlations in long-term stress where human HCC from both summer and winter samplings correlated strongly with dog HCC (summer: N = 57, χ2 = 23.697, P < 0.001, β = 0.235; winter: N = 55, χ2 = 13.796, P < 0.001, β = 0.027). Interestingly, the dogs’ activity levels did not affect HCC, nor did the amount of training sessions per week, showing that the HCC levels were not related to general physical activity. Additionally, there was a seasonal effect in HCC. However, although dogs’ personalities had little effects on their HCC, the human personality traits neuroticism, conscientiousness, and openness significantly affected dog HCC. Hence, we suggest that dogs, to a great extent, mirror the stress level of their owners.
