Results from the randomized controlled trial 'Lifestyle in Pregnancy' (LiP). Diabet Med 2014; 31:1323-30.

Abstract
AIMS The Lifestyle in Pregnancy intervention in obese pregnant women resulted in significantly lower gestational weight gain compared with the control group, but without improvement in rates of clinical pregnancy complications. The impact of the lifestyle intervention on metabolic measurements in the study participants is now reported. METHODS The Lifestyle in Pregnancy study was a randomized controlled trial among 360 obese women (BMI 30-45 kg/m²) who were allocated in early pregnancy to lifestyle interventions with diet counselling and physical activities or to the control group. Fasting blood samples, including plasma glucose, insulin, lipid profile and capillary blood glucose during a 2-h oral glucose tolerance test were carried out three times throughout pregnancy. Insulin resistance was estimated with the homeostasis model assessment of insulin resistance. RESULTS Three hundred and four women (84%) were followed until delivery. Women in the intervention group had a significantly lower change in insulin resistance (HOMA-IR) from randomization to 28-30 weeks' gestation compared with control subjects (mean ± SD: 0.7 ± 1.3 vs. 1.0 ± 1.3, P = 0.02). Despite a significantly lower gestational weight gain in the intervention group, there was no difference between the groups with respect to total cholesterol, HDL, LDL or triglycerides. CONCLUSIONS Lifestyle intervention in obese pregnant women resulted in attenuation of the physiologic pregnancy-induced insulin resistance. Despite restricted gestational weight gain, there were no changes in glucose or lipid metabolism between the groups.

Abstract
OBJECTIVE The aim of this study was to describe the use of antibiotics in a national population-based cohort of pregnant Danish women between 2000 and 2010. DESIGN Register-based, population-wide, cohort study. SETTING Denmark, from 2000 to 2010. POPULATION All pregnancies among Danish residents during the period 2000-2010 were included for analysis. METHODS Data were obtained from the Danish Medical Birth Registry, the Danish National Patient Registry, and the Registry of Medicinal Product Statistics. The filled prescriptions for systemic antibacterial, antimycotic, and antiviral drugs, as well as intravaginally applied antibiotics, were analysed. Associations with demographic variables were assessed using multivariate analysis. MAIN OUTCOME MEASURES Filled prescriptions for antibiotic drugs during pregnancy. RESULTS We included 987 973 pregnancies in Denmark from 2000 to 2010; 38.9% of women with a delivery and 14.8% of women with a miscarriage or termination of pregnancy had one or more antibiotic treatments during pregnancy. Systemic antibacterial drugs were the most frequently used drug group, with filled prescriptions for 33.4% of all deliveries and 12.6% of all abortions. This proportion increased from 28.4% in 2000 to 37.0% in 2010 among deliveries. The biggest change was seen for pivmecillinam, which increased among deliveries from 6.3% in 2000 to 19.5% in 2010. Obese (odds ratio 1.51; 95% CI 1.47-1.56), young (odds ratio 1.35; 95% CI 1.30-1.39), and low-educated women (odds ratio 1.37; 95% CI 1.35-1.1.39) tended to fill more prescriptions of antibiotics during pregnancy. CONCLUSIONS Overall, the number of women who filled prescriptions of antibiotics increased during the 11-year study period. In 2010, at least 41.5% of all deliveries were exposed to antibiotic therapy during pregnancy.

Abstract
We aimed to study the occurrence of acute-onset symptoms at initial presentation in a national Danish cohort of patients with childhood- or adult-onset craniopharyngioma, and to investigate potential risk factors for acute presentation. Medical records of 189 consecutive patients (39 children, 150 adults) presenting with craniopharyngioma during the period 1985-2004 were reviewed, and data regarding initial symptoms, neuroimaging results, vision and pituitary function were systematically collected. Acute symptoms preceding hospital admission were noted. Subgroup analyses were based on age, gender and calendar year period. Potential risk factors for acute presentation were analysed through uni- and multivariate analyses. Acute symptoms were reported in 24 (13%) patients. Acute visual symptoms, headache, nausea or vomiting were most frequently reported, and acute symptoms were more frequent among children (28%) than among adults (9%) (P < 0.01). There were no differences according to sex or calendar year period. Hydrocephalus was present in half of childhood cases and one-fifth of adult patients (P < 0.001). Intra-tumour haemorrhage was seen in two cases. Acute symptoms were more frequent among patients with tumours occupying the third ventricle (P < 0.01), radiologic signs of calcification (P < 0.05) or hydrocephalus (P < 0.01). In multivariate analysis, however, only childhood onset (P < 0.05) and calcification (P < 0.05) were independent risk factors for acute presentation. Craniopharyngioma presented with acute symptoms in 13% of patients. Childhood onset and radiologic signs of calcification were independent risk factors for acute presentation. Intra-tumour haemorrhage was rare.

Abstract
CONTEXT In pregnancy, vitamin D insufficiency and deficiency, defined as serum 25-hydroxyvitamin D (25(OH)D) <50 nM, and <25 nM, respectively, may have adverse effects for both mother and child. Prevalence estimates, and identification of subgroups at special risk, may be useful for the planning of preventive strategies. OBJECTIVE To study the prevalence and risk factors of hypovitaminosis D in early pregnancy. DESIGN AND METHODS In a cross-sectional study of 1348 women in early pregnancy from the Odense Child Cohort, Denmark, 25(OH)D was determined and correlated to demographic and lifestyle variables (age, nationality, skin tone, parity, prepregnancy body mass index (BMI), smoking and sun exposure), using multiple linear and logistic regression analyses for all year, or stratified for summer and winter. The risk of vitamin D insufficiency was expressed as odds ratios (OR) with 95% confidence intervals in brackets. RESULTS The prevalence of vitamin D insufficiency and deficiency was estimated to 27·8% and 3·5% respectively. In adjusted analyses, vitamin D insufficiency was directly associated with winter season, OR = 1·89 (1·35-2·63); increasing prepregnancy BMI, OR = 1·06 (1·03-1·10); and smoking, OR = 2·7 (1·34-5·41); but was less frequent in nulliparous, OR = 0·47 (0·33-0·68) and tanned Caucasians, OR = 0·63 (0·41-0·97). Season-specific associations having parental origin from outside Europe in summer, OR = 4·13 (1·41-12·13); in winter smoking, OR = 3·15 (1·19-8·36); and prepregnancy BMI, OR = 1·12 (1·06-1·18). CONCLUSIONS Vitamin D insufficiency was widespread in early pregnancy. Associations to smoking, prepregnancy BMI and origin outside Europe varied with season. Multiparity and not being tanned in Caucasians represent new risk factors of vitamin D insufficiency.

Abstract
Bleeding episodes in five haemophiliacs with antibody to F VIII were treated by activated F IX concentrate (FEIBA). Relief of pain and haemostasis in affected muscles and joints were recorded in each case. One patient developed a mild attack of disseminated intravascular coagulation with an uneventful recovery. A substantial rise in natural inhibitors of coagulation was seen in two patients, and all but one experienced a rise in F VIII antibody titer.

Abstract
To evaluate the usefulness of haemoglobin A1c (HBA1C) determinations in the diagnosis of diabetes mellitus, the outcome of a standard oral glucose tolerance test (OGTT) and HbA1c values were compared in 178 consecutive subjects referred for a diagnostic OGTT. The subjects were mainly in age groups in which non-symptomatic diabetes mellitus predominates. The prevalences of elevated fasting plasma glucose and abnormal OGTT were found to increase with increasing age. One third of the total series had impaired or diabetic OGTT. In the group with normal OGTT, 16% had fasting plasma glucose concentrations above the upper normal limit, but the range of HbA1c values did not differ from that of healthy controls. In the group with impaired OGTTs (n = 20), elevated HbA1c values were found only in subjects with elevated fasting plasma glucose and the highest two-hour OGTT values (n = 4). In the group with diabetic OGTT, 86-94% had HbA1c values above the upper normal limit, and HbA1c was elevated in all subjects with a fasting plasma glucose higher than 10.5 mmol/l or a 2-hour OGTT glucose value above 14.4 mmol/l. Using the results of the OGTT as the true diagnosis, HbA1c had a diagnostic specificity of 0.78 and sensitivity of 0.96. Only subjects with a substantially reduced glucose tolerance may be diagnosed by HbA1c determinations.

Abstract
In a prospective consecutive study, 68 patients with various liver diseases and 67 control persons were examined for the occurrence of smooth muscle antibodies (SMA), antinuclear antibodies (ANA) and mitochondrial antibodies (MTA) of IgG, IgA and IgM class. A determination of serum immunoglobulins (S-IgG, S-IgA and S-IgM) was also performed. IgG-SMA in titres of greater than 80 occurred in 8 of 12 patients (67%) with hepatitis B antigen (HBag)-negative chronic active liver disease (CALD) and not in other diseases. Apart from one patient with primary biliary cirrhosis (PBC), IgG-ANA in titres of greater than 40 were likewise detected only in HBag-negative CALD (33%). The titres of IgG-SMA and IgG-ANA varied analogously with the biochemical liver parametres. There was a mutual exclusion between HBag and IgG-SMA/-ANA in titres of greater than 20, while IgM-SMA occured in titres of 80 in two patients with HBag-positive CALD. The incidence and titres of IgM-SMA and -ANA were not higher than in the controls. IgA-SMA and -ANA were detected only sporadically. The MTA demonstrated were of IgG PCLASS AND TITRES OF GREATER THAN 40 WERE FOUND ONLY IN PATIENTS WITH PBC (4 of 5). Som of the patients in all groups had an increased conenctration of one or more of the serum immunoglobulins. S-IgG levels were found to be significantly higher in CALD than in the other groups

Abstract
BACKGROUND AND OBJECTIVE Previous studies on hypopituitarism and mortality have concluded that insufficient pituitary function is associated with decreased survival. For several reasons the results are difficult to compare - particularly because definitions and treatment of hypopituitarism have varied and various underlying disorders have been included. The purpose was to assess the relationship between mortality and pituitary function. PATIENTS AND DESIGN One hundred and sixty consecutive patients (99 men and 61 women) with functionless, suprasellar pituitary adenoma. All were operated on transsphenoidally during the period 1985-1996. Additional radiotherapy was given to 29 patients. Mortality was calculated 12.4 years (median, range 8.1-19.9) after operation. Postoperative hormonal deficits were treated in most, though GH substitution was given only to a minority of patients. RESULTS Postoperatively 30% of the patients had normal pituitary function (normal adrenocortical, thyroid and gonadal function), 26% were panhypopituitary and 36% had partial pituitary insufficiency. Forty-one patients had died (34.7 expected) yielding a standard mortality ratio (SMR) of 1.18 (95% confidence limits (CI) 0.87-1.60). SMR was significantly increased in women (1.97, CI 1.20-3.21) but not in men (0.83, CI 0.55-1.26). SMR in patients with normal pituitary function, panhypopituitarism and partial insufficiency were not different from that in the general population. SMR in hypopituitary women was substantially higher than in men with pituitary insufficiency. Treatment with growth hormone in GH-deficient patients did not influence survival. CONCLUSION Pituitary surgery for nonfunctioning adenoma and subsequent pituitary insufficiency had no effect on mortality in men, but was associated with significantly increased mortality in women. Suboptimal hormonal substitution in women may play a role.

Abstract
BACKGROUND AND OBJECTIVE There is agreement in the literature that pituitary apoplexy is a rare disorder. As our experience differs from this view, we analysed the incidence in patients operated on for a nonfunctioning pituitary adenoma. PATIENTS AND DESIGN One hundred ninety-two consecutive patients with a suprasellar, clinically inactive adenoma operated on during the period 1985-1996 were retrospectively reviewed. A diagnosis of pituitary apoplexy was made from relevant neurological symptoms together with pertinent findings at operation. RESULTS Pituitary apoplexy occurred in 41 patients (21%), in 23 patients within 12 days prior to the operation. The male/female ratio was 1.9. Median follow-up time was 13.7 years (range 8.9-19.9). During this period, 12 patients had died, yielding a standard mortality ratio of 1.09 (95% CI 0.62-1.92), similar to that in the patients who had not sustained pituitary apoplexy. Postoperatively, 24% of the patients had normal pituitary function, 38% were panhypopituitary and partial pituitary insufficiency was present in 38%. Subnormal GH secretion was present in virtually all patients tested. Two patients died within 60 days of surgery and in two no or incomplete data were available, although they most likely were panhypopituitary. CONCLUSION Most of our findings add little to what is known about pituitary apoplexy. On one point, however, they are contrary to previously presented data. We found a much higher incidence of pituitary apoplexy despite rather rigorous criteria for the diagnosis. The outcome as regards survival and endocrine function was not different from that in patients with a nonfunctioning adenoma who did not suffer pituitary apoplexy.

Abstract
BACKGROUND The complete correction of highly or extremely myopic eyes to emmetropia can only be achieved by very few procedures: The combination of implanting phacic intraocular lenses and the use of LASIK (laser in-situ keratomileusis) - Bioptic - makes it possible to achieve this goal to a great extent. PATIENTS AND METHODS The Bioptic procedure was carried out on 17 eyes of 10 patients. Two weeks after corneal dissection with the Hansatom,an implantable phacic lens (STAAR) was introduced into the posterior chamber and 4 weeks later the residual myopia was treated with LASIK combined with the correction of astigmatic errors. The follow-up time was 10.2 (6.7) months. RESULTS Preoperative average values of the manifest refraction were -16.22 sph (3.86) with 1.40 cyl (1.30) which changed to -3.85 sph (2.73) with -1.50 cyl (0.87) after implantation of an ICL trade mark into the posterior chamber. Visual acuity increased from uncorrected hand motion to 0.13 (0.10) and corrected from 0.53 (0.19) to 0.63 (0.19). The refraction of implanted ICLs trade mark was 14.6 dpt (1.1). Following the LASIK procedure the uncorrected visual acuity improved to 0.68 (0.16) and fully corrected to 0.79 (0.20). The final refraction measured +0.16 sph (0.67) with -0.48 cyl (0.25). The keratectomy depth was 80.63 -m (26.9) and the optical zone showed a horizontal distance of 6.28 mm (0.39). CONCLUSION Bioptic is able to correct highly and extremely myopic eyes with the combination of phacic lenses and subsequent LASIK. A concomitant astigmatism can be corrected up to 2.5 dpt simultaneously. With the combination of both procedures,the optical zone can be enlarged. Keeping in mind that phacic lenses reveal a constant refraction after a few days and also that LASIK is refractively safe in low myopia of -4 dpt to -5 dpt, it can be expected that the refractive deviation following the Bioptic procedure is low.

Abstract
Fifty-seven IgG monoclonal anti-D antibodies were evaluated in the Rh flow cytometry section, in which 12 laboratories participated. Staining protocols and a fluorescein (FITC)-conjugated Fab fragment goat anti-human IgG (H + L) as a secondary antibody were recommended but not mandatory. A CcDEe red blood cell (RBC) sample that was shown to be homozygous for RHD by molecular methods was supplied and used as internal 'standard RBC' throughout all experiments. An RBC panel comprising two partial D and four weak D types was supplied as well. The use of standard RBC reduced the variability of the data among the laboratories and allowed the conversion of fluorescence data into epitope densities, which were compounded in an antigen density (antigen D per RBC). The highest antigen density was determined for DVI type III, followed by DVII and weak D type 3; the lowest antigen density were determined for weak D type 1 and type 2. Nine of the 12 participating laboratories discriminated three groups of aberrant RhD that had similar Rhesus indices (RI): D category VI with RI = 0; weak D type 2 and type 3 with an high RI; and D category VII and weak D type 1 with an intermediate RI. The antigen densities and the Rhesus indices obtained correlated well among the laboratories of this Workshop section despite different staining protocols, secondary antibodies and instrumentation.

Abstract
A primary metabolic disorder may be present in the colonic mucosa of patients with ulcerative colitis. Preserving the epithelium in situ, we evaluated the metabolism of the colonic mucosa of control patients and patients with ulcerative colitis and Crohn's disease. Colonic mucosal strips (approximately 500 mg) were incubated with partially 14C-labeled acetate (C2), butyrate (C4), hexanoate (C6), octanoate (C8), and glucose, and the production of CO2 and ketone bodies was quantitated. Metabolism by small intestinal mucosal strips was also evaluated. Compared with controls, no decrease in either CO2 or ketone body production by colonic strips from patients with either ulcerative colitis or Crohn's disease was observed for any substrate. The CO2 production from each of the C2-C8 fatty acids was the same for colonic and small intestinal strips, whereas CO2 production from glucose was higher in small intestinal strips than in colonic strips. The production of ketone bodies was low in small intestinal strips. A primary metabolic disorder in the colonic mucosa of patients with inflammatory bowel disease was not found.

Abstract
Hydrogen sulfide (HS-) impairs the oxidation of butyrate in colonocytes and is found in excess in feces of patients with ulcerative colitis. The possible pathogenic role of HS- in ulcerative colitis was further investigated. To investigate the metabolic effect of free and bound fecal HS-, isolated rat colonocytes were incubated in the presence of butyrate without and with the addition of (1) HS- in water, (2) sterile filtrates of fecal homogenates supplemented and incubated with HS- and known sources of fecal HS- production, and (3) HS- incubated with fecal agents known to bind HS-. Oxidation rates were obtained by quantifying the production of CO2. Total and free HS-, as well as the fecal ability to bind HS-, were determined in health and ulcerative colitis. Compared to the production of CO2 by colonocytes incubated with 2 mmol/liter of butyrate, the further addition of 1.25 and 2.5 mmol/liter of HS- in water reduced the production of CO2 by 57.6+/-10.0 and 98.9+/-1.4%, respectively. However, when adding fecal filtrate of homogenate supplemented with HS- corresponding to 1.25 and 2.5 mmol/liter of HS- in water, the reduction of CO2 production was only 30.7+/-12.0 and 53.2+/-14.0%, respectively. Neither the fecal level of total or free HS- nor the remarkable fecal ability to bind HS- differed in health or quiescent and active ulcerative colitis. Bound HS- had no or little effect on CO2 production. Addition of fecal filtrate of nonsupplemented homogenate to colonocytes significantly reduced the oxidation of butyrate to CO2 about 25%, which could not be ascribed to fecal HS-. In conclusion, fecal HS- has little effect on butyrate oxidation in colonocytes and does not seem to play a pathogenic role for UC by impairing colonic epithelial metabolism. Other fecal agents seem to be more potent metabolic inhibitors than fecal HS-. The role of colonic contents in the pathogenesis of ulcerative colitis remains circumstantial.

Abstract
BACKGROUND An increased intestinal permeability (IP) may be a pathogenetic factor in Crohn disease (CD). Increases in IP could be an indicator of subclinical disease and precede clinical relapses. We examined whether an increased IP is a valid predictor of relapse in CD. METHODS 27 patients with CD in remission (CDAI <150) and 22 healthy controls ingested 3.7 MBq of 51Cr-EDTA, 20 kBq of 14C-mannitol and 5 g of unlabelled mannitol in 100 ml of distilled water. The percent urine excretion (24 h) of labelled markers was determined. Patients were followed for 1 year or until relapse, defined as CDAI > 150 and > 50 from baseline. RESULTS Median (25th-75th percentiles). The excretion of 51Cr-EDTA was 1.55% (1.13%-2.53%) for patients and 1.20% (1.11%-1.44%) for controls (P = 0.04). Three of 9 patients with a raised, and 6 of 18 patients with a normal, 51Cr-EDTA excretion relapsed (P = 1.00; Fisher's exact test). Thus, the specificity and sensitivity of the 51Cr-EDTA test as a predictor of relapse was 67% and 33%, respectively. The 51Cr-EDTA/14C-mannitol index was 0.060 (0.037-0.093) for patients and 0.045 (0.038-0.054) for controls (P = 0.06). Four of 12 patients with a raised, and 5 of 15 patients with a normal, index relapsed (P = 1.00; Fisher's exact test). Thus, the specificity and sensitivity of the index test as a predictor of relapse was 56% and 44%, respectively. For controls and patients in remission, who were tested twice, variability of and fluctuations in both the 51Cr-EDTA excretion and the index were greatest for patients. CONCLUSIONS This study supports previous findings of an increased IP in patients with CD. Although fluctuations in the permeation of markers were pronounced in CD, neither the excretion of 51Cr-EDTA nor the 51Cr-EDTA/14C-mannitol index test were valid predictors of relapse in CD.

Abstract
The main purpose was to assess the incidence and late outcome of Cushing's syndrome, particularly in Cushing's disease. Information for all patients diagnosed with Cushing's syndrome during an 11-yr period in Denmark was retrieved. The incidence was 1.2-1.7/million.yr (Cushing's disease), 0.6/million.yr (adrenal adenoma) and 0.2/million.yr (adrenal carcinoma). Other types of Cushing's syndrome were rare. In 139 patients with nonmalignant disease, 11.1% had died during follow-up (median, 8.1 yr; range, 3.1-14.0), yielding a standard mortality ratio (SMR) of 3.68 [95% confidence interval (CI), 2.34-5.33]. The SMR was partly attributable to an increased mortality within the first year after diagnosis. Eight patients died before treatment could be undertaken. The prognosis in patients with malignant disease was very poor. Patients in whom more than 5 yr had elapsed since initial surgery were studied separately, including a questionnaire on their perceived quality of health. In 45 patients with Cushing's disease who had been cured through transsphenoidal neurosurgery, only 1 had died (SMR, 0.31; CI, 0.01-1.72) compared with 6 of 20 patients with persistent hypercortisolism after initial neurosurgery (SMR, 5.06; CI, 1.86-11.0). In patients with adrenal adenoma, SMR was 3.95 (CI, 0.81-11.5). The perceived quality of health was significantly impaired only in patients with Cushing's disease and appeared independent of disease control or presence of hypopituitarism. It is concluded that 1) Cushing's syndrome is rare and is associated with increased mortality, in patients with no concurrent malignancy also; 2) the excess mortality was mainly observed during the first year of disease; and 3) the impaired quality of health in long-term survivors of Cushing's disease is not fully explained.
