- AbstractObjective: To study trough levels of metformin in serum and its intra individual variation in patients using a newly developed assay. Research Design and Methods: Trough serum levels of metformin was measured once using Liquid Chromatography Tandem Mass Spectrometry (LcMSMS) in 137 type 2 diabetes patients with varying renal function (99 men) and followed repeatedly during two months in 20 patients (16 men) with estimated GFR (eGFR) below 60 ml/min/1.73 m(2) body surface. Results: Patients with eGFR >60, 30-60, and <30 ml/min/1.73 m(2) had a median trough metformin concentration of 4.5 mumol/l (range 0.1-20.7, n=107), 7.71 mumol/l (0.12-15.15, n=21), and 8.88 mumol/l (5.99-18.60, n=9), respectively. The median intraindividual overall coefficient of variation (CV) was 29.4 % (range 9,8-74,2). Conclusions: Determination of serum metformin with the LCMSMS technique is useful in patients on metformin treatment. Few patients had values over 20 mumol/L. Metformin measurement is less suitable for dose titration.

- The aim was to explore beliefs about health, illness and health care in women with gestational diabetes mellitus (GDM) managed in two different organisations based on diabetology or obstetrics.Semi-structured interviews were made in two different clinics. clinic A: a specialist diabetes clinic with regular contact with a diabetologist and antenatal care provided by a midwifeclinic B: a specialist maternity clinic providing regular contact with a midwife, a structured programme for self-monitoring of blood glucose and insulin treatment, and a 1-day diabetes class by an obstetrician, a diabetologist, a midwife and a dietician. The clinics were located at two different university hospitals in Sweden.Participants were a consecutive sample of Swedish women diagnosed with GDM; 13 managed in clinic A and 10 managed in clinic B.The findings showed that women described their perceptions of as well-being, being healthy and freedom from disease. All respondents reported a delay in the provision of information about GMD and an information gap about GDM and the management of the condition, from diagnosis until the start of treatment at the specialist clinic. Respondents from clinic A expressed fear about future development of type 2 diabetes. Women from clinic B discussed different causes of GDM, and many claimed that health-care staff informed them that GDM was a transient condition during pregnancy. Respondents from clinic A reported a conflict in their treatment of pregnancy and GDM as two different conditions.Beliefs differed and were related to the health-care model chosen.

- IMPORTANCE The majority of individuals with type 1 diabetes do not meet recommended glycemic targets. OBJECTIVE To evaluate the effects of continuous glucose monitoring in adults with type 1 diabetes treated with multiple daily insulin injections. DESIGN, SETTING, AND PARTICIPANTS Open-label crossover randomized clinical trial conducted in 15 diabetes outpatient clinics in Sweden between February 24, 2014, and June 1, 2016 that included 161 individuals with type 1 diabetes and hemoglobin A(1c) (HbA(1c)) of at least 7.5%(58 mmol/mol) treated with multiple daily insulin injections. INTERVENTIONS Participants were randomized to receive treatment using a continuous glucose monitoring system or conventional treatment for 26 weeks, separated by a washout period of 17 weeks. MAIN OUTCOMES AND MEASURES Difference in HbA(1c) between weeks 26 and 69 for the 2 treatments. Adverse events including severe hypoglycemia were also studied. RESULTS Among 161 randomized participants, mean age was 43.7 years, 45.3% were women, and mean HbA(1c) was 8.6%(70 mmol/mol). A total of 142 participants had follow-up data in both treatment periods. Mean HbA(1c) was 7.92%(63 mmol/mol) during continuous glucose monitoring use and 8.35%(68 mmol/mol) during conventional treatment (mean difference, -0.43% [95% CI, -0.57% to -0.29%] or -4.7 [-6.3 to -3.1 mmol/mol]; P < .001). Of 19 secondary end points comprising psychosocial and various glycemic measures, 6 met the hierarchical testing criteria of statistical significance, favoring continuous glucose monitoring compared with conventional treatment. Five patients in the conventional treatment group and 1 patient in the continuous glucose monitoring group had severe hypoglycemia. During washout when patients used conventional therapy, 7 patients had severe hypoglycemia. CONCLUSIONS AND RELEVANCE Among patients with inadequately controlled type 1 diabetes treated with multiple daily insulin injections, the use of continuous glucose monitoring compared with conventional treatment for 26 weeks resulted in lower HbA(1c). Further research is needed to assess clinical outcomes and longer-term adverse effects.

- OBJECTIVE: To investigate whether genetic susceptibility to type 1 diabetes or maturity-onset diabetes of the young (MODY) increases susceptibility to gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS: We studied mutations in MODY1-4 genes, the presence of GAD antibodies, and HLA DQB1 risk genotypes in 66 Swedish women with GDM and a family history of diabetes. An oral glucose tolerance test was repeated in 46 women at 1 year postpartum. RESULTS: There was no increase in type 1 diabetes-associated HLA-DQB1 alleles or GAD antibodies when compared with a group of type 2 diabetic patients (n = 82) or healthy control subjects (n = 86). Mutations in known MODY genes were identified in 3 of the 66 subjects (1 MODY2, 1 MODY3, and 1 MODY4). Of the 46 GDM subjects, 2 had diabetes (4%) and 17 had impaired glucose tolerance (IGT) (37%) at 1 year postpartum. Of the two subjects who developed manifest diabetes, one carried a MODY3 mutation (A203H in the hepatocyte nuclear factor-1alpha gene). There was no increase in high-risk HLA alleles or GAD antibodies in the women who had manifest diabetes or IGT at 1 year postpartum. CONCLUSIONS: MODY mutations but not autoimmunity contribute to GDM in Swedish women with a family history of diabetes and increase the risk of subsequent diabetes.

- BACKGROUND: To investigate which factors during gestational diabetes pregnancies correlate with the risk of developing impaired glucose tolerance or diabetes 1 year postpartum and to compare this risk in women with gestational diabetes and women with a normal oral glucose tolerance test during pregnancy. METHODS: Of 315 women with gestational diabetes, defined as a 2-hr blood glucose value of at least 9.0 mmol/l at a 75-g oral glucose tolerance test, who delivered in Lund 1991-99, 229 (73%) performed a new test 1 year postpartum. We compared maternal and fetal factors during pregnancy with the test value at follow up. A control group of 153 women with a 2-hr test value below 7.8 mmol/l during pregnancy were invited to a new test 1 year postpartum and 60 (39%) accepted. RESULTS: At 1 year follow up, 31% of the women with gestational diabetes but only one of the 60 controls showed pathologic glucose tolerance and one had developed diabetes. The following factors in women with gestational diabetes were identified as predicting impaired glucose tolerance or diabetes at 1 year follow up: maternal age over 40 and--in a multiple regression analysis, independent of each other--a high 2-hr value at oral glucose tolerance test during pregnancy and insulin treatment during pregnancy. CONCLUSION: The risk of developing manifest diabetes after gestational diabetes may be high enough to justify a general screening or diagnostic procedure in all pregnant women to identify women with gestational diabetes and a postpartum follow up program for them. This study did not identify any particular factor during pregnancy with enough precision to predict a later progression to diabetes.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents a pilot study on the prosodic marking of a contrastive topic in Southern Swedish. A test sentence was elicited in three experimental conditions: initial focus; final focus; contrastive topic (initial word) plus focus (final word). F0 patterns were analysed in recordings of 10 speakers. A majority of the speakers distinguished clearly between the conditions, but speakers employed different strategies. The most common one involved modifying the range and/or level of the F0 patterns given by the lexical pitch accents. Another frequent strategy involved a rising pitch accent on the initial word, where the lexical pitch accent would normally stipulate a fall. This result was unexpected and indicates that Southern Swedish sentence intonation might be more complex than typically assumed.
