- 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.

- Aims The aim of this study was to examine the fear of hypoglycaemia and its association with demographic and disease-specific variables in a large and unselective population of adult patients with Type 1 diabetes. Methods Questionnaires were sent by post to all patients with Type 1 diabetes who were identified in the local diabetes registries of two hospitals in Stockholm, Sweden (n = 1387). Fear of hypoglycaemia was measured using the Swedish Hypoglycaemia Fear Survey, the Worry subscale and the Aloneness subscale. Demographic variables and disease-specific factors were collected from patients' self reports and medical records. Univariate analysis and multiple stepwise linear regression analysis were used in the statistical analyses of the data. Results Seven hundred and sixty-four (55%) patients participated in the study (mean age 43.3 years and mean HbA(1c) 7.0%, normal < 5.0%). The Hypoglycaemia Fear Survey - Worry subscale was significantly associated with frequency of severe hypoglycaemia, number of symptoms during mild hypoglycaemia, gender, hypoglycaemic symptoms during hyperglycaemia and hypoglycaemic unawareness. The Hypoglycaemia Fear Survey - Aloneness subscale was significantly associated with frequency of severe hypoglycaemia, number of symptoms during mild hypoglycaemia, gender, frequency of mild hypoglycaemia, HbA(1c) , hypoglycaemic unawareness and visits to the emergency room because of severe hypoglycaemia. Fear of hypoglycaemia proved to be more prevalent in females and indicated a different pattern between genders in relation to factors associated with fear of hypoglycaemia. Conclusions This study identifies the frequency of severe hypoglycaemia as the most important factor associated with fear of hypoglycaemia. Moreover, for the first time, we document gender differences in fear of hypoglycaemia, suggesting that females are more affected by fear of hypoglycaemia than men.

- Context:Dapagliflozin, a selective sodium-glucose cotransporter 2 (SGLT2) inhibitor, reduces hyperglycemia in patients with type 2 diabetes mellitus (T2DM) by increasing urinary glucose excretion, and weight loss is a consistent associated finding.Objectives:Our objectives were to confirm weight loss with dapagliflozin and establish through body composition measurements whether weight loss is accounted for by changes in fat or fluid components.Design and Setting:This was a 24-wk, international, multicenter, randomized, parallel-group, double-blind, placebo-controlled study with ongoing 78-wk site- and patient-blinded extension period at 40 sites in five countries.Patients:Included were 182 patients with T2DM (mean values: women 63.3 and men 58.6 yr of age; hemoglobin A1c 7.17%, body mass index 31.9 kg/m2, and body weight 91.5 kg) inadequately controlled on metformin.Intervention:Dapagliflozin 10 mg/d or placebo was added to open-label metformin for 24 wk.Main Outcome Measures:Primary endpoint was total body weight (TBW) change from baseline at wk 24. Key secondary endpoints were waist circumference and dual-energy x-ray absorptiometry total-body fat mass (FM) changes from baseline at wk 24, and patient proportion achieving body weight reduction of at least 5% at wk 24. In a subset of patients, magnetic resonance assessment of visceral adipose tissue (VAT) and sc adipose tissue (SAT) volume and hepatic lipid content were also evaluated.Results:At wk 24, placebo-corrected changes with dapagliflozin were as follows: TBW, −2.08 kg [95% confidence interval (CI) = −2.84 to −1.31; P < 0.0001]; waist circumference, −1.52 cm (95% CI = −2.74 to −0.31; P = 0.0143); FM, −1.48 kg (95% CI = −2.22 to −0.74; P = 0.0001); proportion of patients achieving weight reduction of at least 5%, +26.2% (95% CI = 15.5 to 36.7; P < 0.0001); VAT, −258.4 cm3 (95% CI = −448.1 to −68.6; nominal P = 0.0084); SAT, −184.9 cm3 (95% CI = −359.7 to −10.1; nominal P = 0.0385). In the dapagliflozin vs. placebo groups, respectively, serious adverse events were reported in 6.6 vs. 1.1%; events suggestive of vulvovaginitis, balanitis, and related genital infection in 3.3 vs. 0%; and lower urinary tract infections in 6.6 vs. 2.2%.Conclusions:Dapagliflozin reduces TBW, predominantly by reducing FM, VAT and SAT in T2DM inadequately controlled with metformin.

- Background: The compressed curriculum in modern knowledge-intensive medicine demands useful tools to achieve approved learning aims in a limited space of time. Web-based learning can be used in different ways to enhance learning. Little is however known regarding its optimal utilisation. Our aim was to investigate if the individual learning styles of medical students influence the choice to use a web-based ECG learning programme in a blended learning setting. Methods: The programme, with three types of modules (learning content, self-assessment questions and interactive ECG interpretation training), was offered on a voluntary basis during a face to face ECG learning course for undergraduate medical students. The Index of Learning Styles (ILS) and a general questionnaire including questions about computer and Internet usage, preferred future speciality and prior experience of E-learning were used to explore different factors related to the choice of using the programme or not. Results: 93 (76%) out of 123 students answered the ILS instrument and 91 the general questionnaire. 55 students (59%) were defined as users of the web-based ECG-interpretation programme. Cronbach's alpha was analysed with coefficients above 0.7 in all of the four dimensions of ILS. There were no significant differences with regard to learning styles, as assessed by ILS, between the user and non-user groups; Active/Reflective; Visual/Verbal; Sensing/Intuitive; and Sequential/Global (p = 0.56-0.96). Neither did gender, prior experience of E-learning or preference for future speciality differ between groups. Conclusion: Among medical students, neither learning styles according to ILS, nor a number of other characteristics seem to influence the choice to use a web-based ECG programme. This finding was consistent also when the usage of the different modules in the programme were considered. Thus, the findings suggest that web-based learning may attract a broad variety of medical students.

- Aims/hypothesis We reassessed the validity of previously reported incidence rates for type 1 diabetes in 0-34 year olds in Sweden. We estimated new incidence rates through three nationwide registers. Methods We used capture-recapture methods to assess ascertainment in the Diabetes Incidence Study in Sweden (DISS) and estimated incidence rates in the 20-34 year age group for 2007-2009. We examined whether incidence rates in patients aged 34 and younger could be estimated through the Prescribed Drug Register (PDR) via a proxy for diagnosis of type 1 diabetes; men with at least one and women with at least three prescriptions for insulin were included if they had not been given oral glucose-lowering drugs. We scrutinised the proxy by comparing incidence rates in patients aged 14 and younger with the Swedish Childhood Diabetes Register (SCDR), which has 95-99% ascertainment, and by assessing diabetes type among 18-34 year olds in the National Diabetes Register (NDR). Results Incidence rates were two to three times higher than previously reported. The absolute number of cases (2007-2009, age 20-34) was 435 in the DISS, 923 in the NDR, 1,217 in the PDR, 1,431 in all three and 1,617 per the capture-recapture method. Ascertainment in the DISS was similar to 29% for 2007-2009. The proxy diagnosis in the PDR was highly reliable, while the capture-recapture method presumably generated an overestimate. Conclusions/interpretation The incidence of type 1 diabetes in patients aged 34 and younger was two to three times higher than previously reported. The PDR can be used to reliably assess incidence rates in this age group.
