- Among persons living with type 1-diabetes hypoglycemia and fear of hypoglycemia remain limiting barriers for achieving optimal glucose control and a good quality of life. Fear of hypoglycemia has been found stable over time if not treated. Uncooked cornstarch has been found to reduce the risk of hypoglycemia but has not been studied in relation to fear of hypoglycemia. The aims of this study were to through clinical data, self-reported measures and clinical interviews explore subjects’ experience of using uncooked cornstarch before bedtime and their beliefs and experiences of fear of hypoglycemia. Methods: Mixed methods with both quantitative and qualitative data were used. Self-reported measures of hypoglycemia and fear of hypoglycemia were compared to subjects’ responses during a clinical interview. The interviews were analyzed with a functional behavior analytical approach. Results: A total of five subjects took part in the study. One subject perceived the uncooked cornstarch helpful in reducing hypoglycemia. Several subjects could recall frightening hypoglycemic episodes triggering their fear. Three out of the five subjects reported avoidance behaviors such as excessive self-monitoring of blood glucose or overeating related to fear of hypoglycemia. Conclusions: The uncooked cornstarch was found appetizing but was not perceived as having an effect on BG or hypoglycemia frequency. The clinical interviews confirmed previous research regarding experience of hypoglycemia and fear of hypoglycemia.

- Aims: To investigate fear of hypoglycaemia (FoH) longitudinally in a cross‐sectional study of adult patients with type 1 diabetes. Specifically, we investigated two subgroups of patients who over 4 years either showed a substantial increase or decrease in level of FoH to identify factors associated with changes in FoH.Methods: The Swedish version of the Hypoglycaemia Fear Survey (HFS) along with a questionnaire to assess hypoglycaemia history was sent by mail to 764 patients in 2010. The responders in 2010 (n = 469) received another set of the same two questionnaires in 2014. HbA1c, insulin regimen, weight and creatinine from 2010 and 2014 were obtained from medical records. Those with an absolute difference in HFS scores ≥ 75th percentile were included in the subgroup analyses. Statistical analyses included one‐sample t tests, chi‐square and McNemar's test.Results: The absolute difference in the HFS total score (n = 347) between 2010 and 2014 was m = ±7.6, SD ± 6. In the increased FoH group, more patients reported a high level of moderate hypoglycaemic episodes as well as impaired awareness of hypoglycaemia in 2014 compared with the decreased FoH group. There were more subjects in the increased FoH group with insulin pumps in 2014 and in 2010. In the decreased FoH group, more patients had a high frequency of daily self‐monitoring of blood glucose (SMBG) in 2010 and in 2014.Conclusions: Fear of hypoglycaemia is stable across time for most patients. Changes in fear level are associated with changes in hypoglycaemia frequency. Thus, asking patients about changes in hypoglycaemia experiences is of great importance.

- OBJECTIVE: The major aims of this study were to examine (1) the association between fear of hypoglycemia (FOH) in adults with type 1 diabetes with demographic, psychological (anxiety and depression), and disease-specific clinical factors (hypoglycemia history and unawareness, A1c), including severe hypoglycemia (SH), and (2) differences in patient subgroups categorized by level of FOH and risk of SH.RESEARCH DESIGN AND METHODS: Questionnaires were mailed to 764 patients with type 1 diabetes including the Swedish translation of the Hypoglycemia Fear Survey (HFS) and other psychological measures including the Perceived Stress Scale, Hospital Anxiety and Depression Scale, Anxiety Sensitivity Index, Social Phobia Scale, and Fear of Complications Scale. A questionnaire to assess hypoglycemia history was also included and A1c measures were obtained from medical records. Statistical analyses included univariate approaches, multiple stepwise linear regressions, Chi-square t tests, and ANOVAs.RESULTS: Regressions showed that several clinical factors (SH history, frequency of nocturnal hypoglycemia, self-monitoring) were significantly associated with FOH but R (2) increased from 16.25 to 39.2 % when anxiety measures were added to the model. When patients were categorized by level of FOH (low, high) and SH risk (low, high), subgroups showed significant differences in non-diabetes-related anxiety, hypoglycemia history, self-monitoring, and glycemic control.CONCLUSION: There is a strong link between FOH and non-diabetes-related anxiety, as well as hypoglycemia history. Comparison of patient subgroups categorized according to level of FOH and SH risk demonstrated the complexity of FOH and identified important differences in psychological and clinical variables, which have implications for clinical interventions.

- Background: The estrogen receptor (ER) can change expression between primary tumor (PT) and distant metastasis (DM) in breast cancer. A tissue biopsy reflects a momentary state at one location, whereas circulating tumor cells (CTCs) reflect real-time tumor progression. We evaluated ER-status during tumor progression from PT to DM and CTCs, and related the ER-status of CTCs to prognosis. Methods: In a study of metastatic breast cancer, blood was collected at different timepoints. After CellSearch® enrichment, CTCs were captured on DropMount slides and evaluated for ER expression at baseline (BL) and after 1 and 3 months of therapy. Comparison of the ER-status of PT, DM, and CTCs at different timepoints was performed using the McNemar test. The primary endpoint was progression-free survival (PFS). Results: Evidence of a shift from ER positivity to negativity between PT and DM was demonstrated (p = 0.019). We found strong evidence of similar shifts from PT to CTCs at different timepoints (p <0.0001). ER-positive CTCs at 1 and 3 months were related to better prognosis. Conclusions: A shift in ER-status from PT to DM/CTCs was demonstrated. ER-positive CTCs during systemic therapy might reflect the retention of a favorable phenotype that still responds to therapy.

- While some of the future impacts of global environmental change such as some aspects of climate change can be projected and prepared for in advance, other effects are likely to surface as surprises - that is situations in which the behaviour in a system, or across systems, differs qualitatively from expectations. Here we analyse a set of institutional and political leadership challenges posed by 'cascading' ecological crises: abrupt ecological changes that propagate into societal crises that move through systems and spatial scales. We illustrate their underlying social and ecological drivers, and a range of institutional and political leadership challenges, which have been insufficiently elaborated by either crisis management researchers or institutional scholars. We conclude that even though these sorts of crises have parallels to other contingencies, there are a number of major differences resulting from the combination of a lack of early warnings, abrupt ecological change, and the mismatch between decision-making capabilities and the cross-scale dynamics of social-ecological change.

- Human skeletal muscle characteristics such as fiber type composition, fiber size and myonuclear content are widely studied in clinical and sports related contexts. Being aware of the methodological and biological variability of the characteristics is a critical aspect in study design and outcome interpretation, but comprehensive data on the variability of morphological features in human skeletal muscle is currently limited. Accordingly, in the present study, m. vastus lateralis biopsies (10 per subject) from young and healthy individuals, collected in a systematic manner, were analyzed for various characteristics using immunohistochemistry (n=7) and SDS-PAGE (n=25). None of the analyzed parameters; fiber type % (FT%), type I and II CSA (fCSA), percentage fiber type area (fCSA%), myosin heavy chain composition (MyHC%), type IIX content, myonuclear content or myonuclear domain varied in a systematic manner longitudinally along the muscle or between the two legs. The average within subject coefficient of variation for FT%, fCSA, fCSA%, and MyHC% ranged between 13-18%, but was only 5% for fiber specific myonuclear content, which reduced the variability for myonuclear domain size to 11-12%. Pure type IIX fibers and type IIX MyHC were randomly distributed and present in <24% of the analyzed samples, with the average content being 0.1 and 1.1%, respectively. In conclusion, leg or longitudinal orientation does not seem to be an important aspect to consider when investigating human vastus lateralis characteristics. However, single muscle biopsies should preferably not be used when studying fiber type and fiber size related aspects given the notable sample to sample variability.

Tidskriftsartikel (refereegranskat)abstract
- One of the most important properties influencing the chemical behavior of an element is the electron affinity (EA). Among the remaining elements with unknown EA is astatine, where one of its isotopes, 211At, is remarkably well suited for targeted radionuclide therapy of cancer. With the At− anion being involved in many aspects of current astatine labeling protocols, the knowledge of the electron affinity of this element is of prime importance. Here we report the measured value of the EA of astatine to be 2.41578(7) eV. This result is compared to state-of-the-art relativistic quantum mechanical calculations that incorporate both the Breit and the quantum electrodynamics (QED) corrections and the electron–electron correlation effects on the highest level that can be currently achieved for many-electron systems. The developed technique of laser-photodetachment spectroscopy of radioisotopes opens the path for future EA measurements of other radioelements such as polonium, and eventually super-heavy elements.
