- Introduction: The effects of the GLP-1 analogue liraglutide on time in hypoglycaemia, time in hyperglycaemia, and time in range for type 2 diabetes patients initially treated with multiple daily insulin injections (MDI) were investigated. Variables associated with hypoglycaemia in the current population were also identified. Methods: Analyses were based on data from a previously performed double-blind, placebo-controlled trial in which 124 MDI-treated patients with type 2 diabetes were randomized to liraglutide or placebo. Masked continuous glucose monitoring (CGM) was performed at baseline and week 24 in 99 participants. Results: The mean time in hypoglycaemia was similar for participants receiving liraglutide and those receiving placebo after 24 weeks of treatment. Mean time in target was greater in the liraglutide group than in the placebo group: 430 versus 244 min/24 h (p < 0.001) and 960 versus 695 min/24 h (p < 0.001) for the two glycaemic ranges considered, 4–7 mmol/l and 4–10 mmol/l, respectively. Mean time in hyperglycaemia was lower in the liraglutide group: 457 versus 723 min/24 h (p = 0.001) and 134 versus 264 min/24 h (p = 0.023) for the two cutoffs considered, > 10 mmol/l and > 14 mmol/l, respectively. Lower mean glucose level, lower C-peptide, and higher glucose variability were associated with an increased risk of hypoglycaemia in both treatment groups. Higher proinsulin level was associated with a lower risk of hypoglycaemia in the liraglutide group. Conclusion: For type 2 diabetes patients initially treated with MDI, introducing liraglutide had a beneficial effect on glucose profiles estimated by masked CGM. Mean glucose level, glycaemic variability, C-peptide, and proinsulin level influenced the risk of hypoglycaemia in this population.

- Objective To evaluate variables associated with hemoglobin A1c (HbA1c) and weight reduction when adding liraglutide to persons with type 2 diabetes treated with multiple daily insulin injections (MDI). Research design and methods This was a reanalysis of a previous trial where 124 patients were enrolled in a double-blind, placebo-controlled, multicenter randomized trial carried out over 24 weeks. Predictors for effect on change in HbA1c and weight were analyzed within the treatment group and with concurrent interaction analyses. Correlation analyses for change in HbA1c and weight from baseline to week 24 were made. Results The mean age at baseline was 63.7 years, 64.8% were men, the mean number of insulin injections was 4.4 per day, the mean daily insulin dose was 105 units and the mean HbA1c was 74.5 mmol/mol (9.0%). The mean HbA1c and weight reductions were 12.3 mmol/mol (1.13%; P<0.001) and 3.8 kg (P<0.001) greater in liraglutide than placebo-Treated persons. There was no significant predictor for greater effect on HbA1c that existed in all analyses (univariate, multivariate and interaction analyses against controls). For a greater weight reduction when adding liraglutide, a lower HbA1c level at baseline was a predictor (liraglutide group P=0.002, P=0.020 for liraglutide group vs placebo). During follow-up in the liraglutide group, no significant correlation was found between change in weight and change in HbA1c (r=0.09, P=0.46), whereas a correlation existed between weight and insulin dose reduction (r=0.44, P<0.001). Conclusion Weight reduction becomes greater when adding liraglutide in patients with type 2 diabetes treated with MDI who had a lower HbA1c level compared with those with a higher HbA1c level. There was no correlation between reductions in HbA1c and weight when liraglutide was added, that is, different patient groups responded with HbA1c and weight reductions.

- BACKGROUND: The relationship between alcohol intake and risk of venous thromboembolism (VTE) is unclear. Men and women differ in their drinking habits, which may affect a possible association.OBJECTIVE: This article investigates the association between alcohol consumption, alcohol dependence and VTE in the total population as well as in men and women separately.METHODS: We performed a prospective, population-based cohort study in northern Sweden. Study participants were 108,025 (51% women) persons aged 30 to 60 years who underwent a health examination between 1985 and 2014. We assessed alcohol consumption and defined alcohol dependence using a questionnaire. The outcome was a validated first-time VTE.RESULTS: The mean follow-up time was 13.9 years, and 2,054 participants had a first-time VTE. The mean alcohol consumption was 3.5 standard drinks weekly in men and 1.5 in women. Alcohol dependence was found in 10% of men and 3% of women. There was an association between alcohol consumption (hazard ratio [HR], 1.02; 95% confidence interval [CI], 1.00-1.03 per standard drink weekly) as well as alcohol dependence (HR, 1.27; 95% CI, 1.06-1.52) and VTE after adjustments. In men, the risk of VTE increased over quartiles of weekly alcohol consumption (p for trend 0.02), with a HR of 1.22 (95% CI, 1.01-1.47) for the highest quartile. Alcohol dependence was associated with VTE in men (HR, 1.30; 95% CI, 1.07-1.59). In women, there were no significant associations.CONCLUSION: High alcohol consumption and alcohol dependence were associated with increased risk of first-time VTE in men, but not in women.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Venous thromboembolism (VTE) is a vascular disease with an incidence of approximately 140 cases per 100,000 person-years in adults. The incidence of VTE has increased over the last decades, and more than 20% of affected individuals die in the first year after diagnosis. To reduce the incidence of VTE, it is important to identify modifiable risk factors for the condition.Aims: The aims of this thesis were a) To study the incidence of first-time VTE and the prevalence of risk markers for VTE at the time of VTE diagnosis, b) To determine the validity of diagnoses of deep vein thrombosis and pulmonary embolism in administrative registries, and c) To study the association between glucose levels, diabetes, alcohol consumption, physical activity and risk of first-time VTE.Methods: To determine the incidence of first-time VTE and the prevalence of risk markers for VTE at the time of VTE diagnosis, a retrospective, population-based cohort study was conducted. The study included all adult residents of Västerbotten County during the year 2006. All other aims were addressed in the prospective, population-based Venous thromboEmbolism In Northern Sweden (VEINS) cohort study. The VEINS cohort included 108,025 residents of Västerbotten County aged 30 to 60 years without previous VTE events. They were included from 1985 onwards and were followed until a VTE event, death, emigration, or the study end on September 5, 2014. All underwent a health examination within the Västerbotten Intervention Programme where weight, height, blood pressure and glucose levels were measured, and answered a questionnaire regarding smoking, education level, medication use, history of diabetes, alcohol intake and physical activity. VTE diagnoses were validated by review of medical records and radiology reports. To study the validity of diagnoses of deep vein thrombosis and pulmonary embolism in administrative registries, a registry search for International Classification of Diseases diagnosis codes indicating pulmonary embolism and/or deep vein thrombosis events was made in the Swedish National Patient Registry and the Cause of Death Registry. An additional search using an extended set of International Classification of Diseases diagnosis codes was performed in order to identify misclassified events.Results: The incidence of first-time VTE was 137 (95% confidence interval [CI] 122–154) per 100,000 adults per year. The most common risk markers for VTE were recent hospitalization and concurrent malignancy. The positive predictive value for a diagnosis of pulmonary embolism was 80.7% (95% CI 78.4–82.9), and that of deep vein thrombosis 59.2% (95% CI 56.7–61.7). Misclassification occurred in 1.1% (95% CI 0.4–1.7) of pulmonary embolism events and in 16.4% (95% CI 14.2–18.7) of deep vein thrombosis events. In the VEINS cohort, a total of 2,054 participants experienced an objectively verified first-time VTE event during approximately 1.5 million person-years of follow-up. In univariable analysis, there were associations between fasting plasma glucose, oral glucose tolerance test two-hour post-load plasma glucose, diabetes and increased risk of first-time VTE. These associations were attenuated after adjustment for potential confounders, and were no longer significant. There was an association between alcohol consumption and risk of first-time VTE in men (P for trend 0.02 after adjustments for increased risk of first-time VTE over quartiles of weekly alcohol consumption). Alcohol dependence was associated with risk of first-time VTE in men (hazard ratio [HR] 1.30; 95% CI 1.07–1.59 after adjustments). In women, there were no significant associations between alcohol consumption and risk of first-time VTE. Women who performed leisure time physical activity at least once a week had a lower risk of first-time VTE (HR 0.83; 95% CI 0.71–0.98 after adjustments) compared to women with less or no physical activity. Women with high occupational physical activity also had a lower risk of first-time VTE (HR 0.85; 95% CI 0.74–0.98 after adjustments). In men, there were no consistent association between either measure of physical activity and risk of first-time VTE. Conclusions: VTE is a common vascular disease. Registry data on diagnoses of pulmonary embolism, but not deep vein thrombosis, is of acceptable quality and can be considered for use in registry-based studies. Glucose levels and diabetes are not associated with risk of first-time VTE. Alcohol intake and alcohol dependence are associated with an increased risk of first-time VTE in men, whereas high leisure time physical activity and occupational physical activity are associated with a decreased risk of first-time VTE in women.

- Background: Physical activity may have a protective effect against venous thromboembolism (VTE). The aim of this study was to investigate the association between leisure time physical activity, occupational physical activity, and the risk of VTE in men and women separately.Methods: The population-based, prospective Venous thromboEmbolism In Northern Sweden (VEINS) cohort study included 108,025 participants of health examinations between 1985 and 2014. Physical activity data were collected by questionnaire. Participants were followed from health examination to first-time VTE event, death, emigration or the end of the study. All VTE events were validated by reviewing medical records and radiology reports.Results: During 1,496,669 person-years, 2054 participants experienced VTE. Women who performed leisure time physical activity at least once a week had a lower risk of first-time VTE (hazard ratio (HR) 0.83; 95% confidence interval (CI) 0.71–0.98 after adjustments) compared with women with less or no physical activity. Furthermore, women with high occupational physical activity also had a lower risk of VTE (HR 0.85; 95% CI 0.74–0.98). In men, there was no consistent association between either measure of physical activity and the risk of VTE.Conclusion: We found an association between increased physical activity and a lower risk of first-time VTE in women.
