- Background: To estimate cardiovascular disease (CVD) mortality in relation to obesity and gender. Methods: Data from 11 prospective cohorts from four European countries including 23 629 men and 21 965 women, aged 24 to 99 years, with a median follow-up of 7.9 years were analyzed. Hazards ratios (HR) for CVD mortality in relation to baseline body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were estimated using Cox proportional hazards models with age as the timescale. Results: Men had higher CVD mortality than women in all four BMI categories (<25.0, 25.0-29.9, 30.0-34.9 and >= 35.0 kg/m(2)). Compared with the lowest BMI category in women, multivariable adjusted HRs (95% confidence intervals) for higher BMI categories are 1.0 (0.8-1.4), 1.6 (1.1-2.1) and 2.8 (2.0-3.8) in women and 2.8 (2.2-3.6), 3.1 (2.5-3.9), 3.8 (2.9-4.9) and 5.4 (3.8-7.7) in men, respectively. Similar findings were observed for abdominal obesity defined by WC, WHR or WHtR. The gender difference was slightly smaller in obese than in non-obese individuals; but the interaction was statistically significant only between gender and WC (p = 0.02), and WHtR (p = 0.01). None of the interaction terms was significant among non-diabetic individuals. Conclusions: Men had higher CVD mortality than women across categories of anthropometric measures of obesity. The gender difference was attenuated in obese individuals, which warrants further investigation.

- Background: Diabetic foot ulcers (DFU) pose a significant health risk in diabetic patients, with insufficient revascularization during wound healing being the primary cause. This study aimed to assess microvessel sprouting and wound healing capabilities using vascular endothelial growth factor (VEGF-A) and a modified fibroblast growth factor (FGF1). Methods: An ex vivo aortic ring rodent model and an in vivo wound healing model in diabetic mice were employed to evaluate the microvessel sprouting and wound healing capabilities of VEGF-A and a modified FGF1 both as monotherapies and in combination. Results: The combination of VEGF-A and FGF1 demonstrated increased vascular sprouting in the ex vivo mouse aortic ring model, and topical administration of a combination of VEGF-A and FGF1 mRNAs formulated in lipid nanoparticles (LNPs) in mouse skin wounds promoted faster wound closure and increased neovascularization seven days post-surgical wound creation. RNA-sequencing analysis of skin samples at day three post-wound creation revealed a strong transcriptional response of the wound healing process, with the combined treatment showing significant enrichment of genes linked to skin growth. Conclusion: f-LNPs encapsulating VEGF-A and FGF1 mRNAs present a promising approach to improving the scarring process in DFU.

Bokkapitel (refereegranskat)abstract
- Care for adolescent patients with diabetes type 1 is a recognized challenge, with known adherence problems in a context where home-/self-care and continuous vital need of day-to-day life-style adjustment. The recommended care regimen often gives rise to conflicts with broader personal and social needs and desires, and in case of weak adherence negative spirals of undermined self-confidence and/or emotional denial further deteriorating the situation may result. The need to adjust care to the specific situation is accepted within the pediatric diabetes professional community, accepting a commitment to person centeredness involving alliance with the family as a critical part. Yet, families can be involved in different ways and the issue of how to involve families and what ethical tensions that may actualize is largely unexplored. Standard models of person- and family-centeredness tell us little about how to involve family members in care similar to that of diabetes. We have elsewhere proposed an alternative approach more attuned to such circumstances, aiming at empowering patients' long-term capacities to manage their condition domestically. This “counselling, self-care, adherence (CSA) approach” offers a look at the role that family can play to improve these types of care. We will illustrate how family members can assist in the care of teenagers with diabetes, but that there are also serious risks actualized by such involvement. In particular, we will highlight ethical complications that arise when the role of a family member is changed from “parent” to “care provider.”

- AIMS: The aims were to describe the food habits of adolescents with Type 1 diabetes (Type 1 DM) and to compare them with healthy control subjects; to describe the distribution of energy-providing nutrients in patients and compare it with current recommendations and previous reports; and finally, to investigate associations between dietary intake and glycaemic control. METHODS: One hundred and seventy-four adolescents with Type 1 DM and 160 age- and sex-matched healthy control subjects completed a validated food frequency questionnaire, and 38 randomly chosen patients completed a prospective 4-day food record. RESULTS: Patients ate more regularly, and more often ate fruit and fruit juice, potatoes and root vegetables, meat, fish, egg, offal and sugar-free sweets than control subjects. Control subjects more often ate ordinary sweets and snacks. Patients chose coarse rye bread and dairy products with less fat to a greater extent than control subjects. Patients were heavier than control subjects. The intake of saturated fat was higher in patients compared with recommendations and, for boys with diabetes, the intake of protein was higher than recommended. Patients with poorer glycaemic control ate vegetables, fruit and fish less often than patients with better control. CONCLUSIONS: The food habits of adolescents with Type 1 DM were healthier than those of control subjects. The intake of energy-providing nutrients was in line with current recommendations and showed improvements compared with previous reports, with the exception of fibre intake. The association between dietary intake and glycaemic control needs further investigation in prospective studies.

- AIMS: To compare the diagnostic usefulness of tuning fork, monofilament, biothesiometer and skin biopsies in peripheral neuropathy in individuals with varying glucose metabolism.METHODS: Normoglycaemic, impaired glucose tolerance (IGT) and type 2 diabetes (T2DM) individuals were recruited. Nerve conduction studies (NCS) and thermal threshold tests were performed. Vibrotactile sense was tested with a biothesiometer and a 128-Hz tuning fork. Touch/pressure perception was examined with a 10-g monofilament. Skin biopsies were performed and intraepidermal nerve fibres were quantified. Distal symmetric polyneuropathy (DSPN) was defined as neuropathy disability score ≥2 and abnormal NCS. Thermal threshold tests were used to define small nerve fibre neuropathy (sDSPN) in cases where NCS (large nerve fibres) were normal.RESULTS: The prevalence of DSPN and sDSPN in the whole group (n=119) was 18% and 23%, respectively. For the biothesiometer, a cut-off of ≥24.5V had a sensitivity of 82% and specificity of 70% (AUC=0.81, 95% CI 0.71-0.91) when evaluating DSPN. An intraepidermal nerve fibre density cut-off of ≤3.39fibres/mm showed a sensitivity of 74% and specificity of 70% in the detection of sDSPN, whereas the sensitivity of the tuning fork and the biothesiometer were relatively low, 46% and 67%, respectively. When combining skin biopsies with the tuning fork, 10 more sDSPN cases were identified. Adding skin biopsy to the combination of the tuning fork and biothesiometer increased the sensitivity of finding sDSPN cases, but not DSPN, from 81% to 93%.CONCLUSION: Using a biothesiometer in clinical routine might be a sensitive method to detect large nerve fibre dysfunction in the lower extremity, whereas skin biopsies in combination with methods measuring vibrotactile sense could increase the diagnostic sensitivity of detecting peripheral neuropathy at an early stage.

Tidskriftsartikel (refereegranskat)abstract
- A carbohydrate-restricted diet is a widely recommended intervention for non-alcoholic fatty liver disease (NAFLD), but a systematic perspective on the multiple benefits of this diet is lacking. Here, we performed a short-term intervention with an isocaloric low-carbohydrate diet with increased protein content in obese subjects with NAFLD and characterized the resulting alterations in metabolism and the gut microbiota using a multi-omics approach. We observed rapid and dramatic reductions of liver fat and other cardiometabolic risk factors paralleled by (1) marked decreases in hepatic de novo lipogenesis; (2) large increases in serum beta-hydroxybutyrate concentrations, reflecting increased mitochondrial beta-oxidation; and (3) rapid increases in folate-producing Streptococcus and serum folate concentrations. Liver transcriptomic analysis on biopsy samples from a second cohort revealed downregulation of the fatty acid synthesis pathway and upregulation of folate-mediated one-carbon metabolism and fatty acid oxidation pathways. Our results highlight the potential of exploring diet-microbiota interactions for treating NAFLD.

- Objectives To study evidence for construct validity, the aim was to describe the outcome from the recently developed Diabetes Questionnaire, assess the associations of that outcome with clinical variables and generic health-related quality of life, and study the sensitivity to differences between clinically relevant groups of glycaemic control in adults with type 1 and type 2 diabetes in a nation-wide setting. Design Cross-sectional survey. Setting Swedish diabetes care clinics connected to the National Diabetes Register (NDR). Participants Among 2479 adults with type 1 diabetes and 2469 with type 2 diabetes selected at random from the NDR, 1373 (55.4%) with type 1 and 1353 (54.8%) with type 2 diabetes chose to participate. Outcome measures The Diabetes Questionnaire, the generic 36-item Short Form version 2 (SF-36v2) health survey and clinical variables. Results Related to the prespecified assumptions, supporting evidence for construct validity for the Diabetes Questionnaire was found. Supporting divergent validity, the statistically significant correlations with the clinical variables were few and weak. In relation to the SF-36v2 and in support of convergent validity, the strongest correlations were seen in the Diabetes Questionnaire scales General Well-being and Mood and Energy. In those scales, machine learning analyses showed that about 40%-45% of the variance was explained by the SF-36v2 results and clinical variables. In multiple regression analyses among three groups with differing levels of glycated haemoglobin adjusted for demographics, other risk factors, and diabetes complications, the high-risk group had, in support of sensitivity to clinically relevant groups, statistically significant lower scores than the well-controlled group in most Diabetes Questionnaire scales. Conclusions This nation-wide study shows that the Diabetes Questionnaire captures some generic health-related quality-of-life dimensions, in addition to adding diabetes-specific information not covered by the SF-36v2 and clinical variables. The Diabetes Questionnaire is also sensitive to differences between clinically relevant groups of glycaemic control.

Tidskriftsartikel (refereegranskat)abstract
- Dynamic artery blood pressure (Finapres) response to active standing up, normally consisting of initial rise, fall and recovery above the baseline (overshoot), was compared with the early steady-state artery blood pressure level to measure sympathetic vasomotor function in healthy subjects (n = 23, age 35 +/- 9 years; mean +/-SD) and in type I diabetic patients without autonomic neuropathy (AN) (group 1: n = 18, 38 +/- 13 years), with AN but no cardiovascular drugs (group 2a: n = 7, 44 +/- 11 years) and with both AN and cardiovascular drugs (group 2b: n = 10, 47 +/- 7 years). Systolic and diastolic overshoot were similar in the control (15 +/- 13/15 +/- 11 mmHg) and group 1 subjects. Systolic overshoot disappeared in 57% of patients in group 2a (-1 +/- 9 mmHg; P < 0.03), whereas artery blood pressure still overshot in diastole (8 +/- 7 mmHg; NS). Systolic overshoot disappeared in all patients in group 2b (-22 +/- 22 mmHg; P < 0.0006) and diastolic overshoot disappeared in 60% of these patients (-6 +/- 16 mmHg; P = 0.0006). Systolic early steady-state level was not lower in group 2a than in group 1 (NS), but it was impaired in group 2b (P < 0.006), in which six diabetic patients had a pathological response beyond the age-related reference values. There was a strong association between the overshoot and steady-state levels (P for chi 2 < 0.001, n = 58). Overshoot of the control subjects and patients in group 2b correlated to their respective steady-state blood pressure levels (r > or = 0.76; P < or = 0.001). In conclusion, baroreceptor reflex-dependent overshoot of the artery blood pressure after active standing up diminishes with the development of AN and it is associated with the early steady-state level of the artery blood pressure.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Mortality rates have declined substantially over the past decades in the general population, but the situation among diabetic subjects is less clear. The aim of this study was to analyze mortality trends in diabetic and nondiabetic subjects during 1972–2004.Research design and methods: Since 1972, all patients with diabetes are entered in a diabetes register at Laxå Primary Health Care Center; 776 incident cases were recorded up to 2001. The register has been supplemented with a nondiabetic population of 3,880 subjects and with data from the National Cause of Death Register during 1972 to 2004.Results: During the 33-year follow-up period, 233 (62.0%) diabetic women and 240 (60.0%) diabetic men and 995 (52.9%) nondiabetic women and 1,082 (54.1%) nondiabetic men died. The age-adjusted hazard ratio (HR) for all-cause mortality among diabetic and nondiabetic subjects was 1.17 (P < 0.0021) for all, 1.22 (P < 0.007) for women, and 1.13 (P = 0.095) for men. The corresponding cardiovascular disease (CVD) mortality HRs were 1.33 (P < 0.0001), 1.41 (P < 0.0003), and 1.27 (P < 0.0093), respectively. The CVD mortality reduction across time was significant in nondiabetic subjects (P < 0.0001) and in men with diabetes (P = 0.014) but not in diabetic women (P = 0.69). The results regarding coronary heart disease (CHD) were similar (P < 0.0001, P < 0.006, and P = 0.17, respectively). The CVD and CHD mortality rate change across time was fairly linear in all groups.Conclusions: Diabetic subjects had less mortality rate reduction during follow-up than nondiabetic subjects. However the excess mortality risk for diabetic subjects was smaller than that found in other studies.

Association between symptoms of neuropathy, nerve conduction and levels of heat shock protein 27 in type 2 diabetes
- 2010
-
Konferensbidrag (refereegranskat)abstract
- Background and aims: Increased levels of serum HSP27 (sHSP27) are associated with distal symmetric polyneuropathy (DSPN) in type 1 diabetic patients. However, the association between nerve function and sHSP27 has not been studied in subjects with type 2 diabetes (T2D) and impaired glucose tolerance (IGT). Thus, our objectives were to investigate the association between nerve conduction in the legs, symptoms of distal polyneuropathy and sHSP27 levels. Methods: Subjects were consecutively recruited from the population-based Västerbotten Intervention Program; controls (n=39, m/f=19/20, mean age=61± 0.6 years), IGT (n=29, m/f=15/14, mean age=61± 0.8 years), T2D (n=51, m/f=30/21, mean age=61± 1.3 years). Nerve conduction studies were performed. Z-scores for motor conduction velocity (CV) of the peroneal nerve, and the sensory CV and amplitude of the sural nerve were measured and compiled into a composite Z-score of the right leg (Z-score leg). Neurological Disability Score (NDS), including examination of sensory perception, reflexes and muscle strength, were used to evaluate symptoms of neuropathy in the leg. NDS and Z-score leg were categorized into tertiles, respectively. sHSP27 levels were measured and divided into low and high levels. Results: Subjects in the highest NDS tertile had lower sHSP27 levels (328 ± 287 pg/mL) compared to subjects in the lowest NDS tertile (558 ± 404 pg/mL, p=0.04). Subjects in the lowest tertile of Z-score leg were in the lowest sHSP27 group (63%) compared to the subjects in the highest group (38%, p=0.034). The highest tertile of Z-score leg was associated with high levels of sHSP27 (OR 3.8, 95% CI 1.2; 11.5, p=0.02); adjusted for age and sex. However, this association was attenuated when adjusted for T2D status (OR 3.1, 95% CI 0.9; 9.9, p=0.06). Conclusion: In summary, increased sHSP27 levels were associated with an increasing Z-score of the leg; thus, a better nerve conduction, and fewer symptoms using the whole study population. The attenuation of the association when including diabetic status indicates an altered HSP27 production in T2D patients compared to controls and subjects with IGT.
