Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is a common pregnancy-related disorder and a well-known risk factor for adverse pregnancy outcomes. There are conflicting findings on the association of GDM with the risk of congenital anomalies (CAs) in offspring. In this study, we aimed to determine study whether maternal GDM is associated with an increased risk of major CAs in offspring. METHODS This Finnish Gestational Diabetes (FinnGeDi) register-based study included 6,597 women with singleton pregnancies and a diagnosis of GDM and 51,981 singleton controls with no diabetes identified from the Finnish Medical Birth Register (MBR) in 2009. Data from MBR were combined in this study with the Register of Congenital Malformations, which includes the data of CAs. We used logistic regression to calculate odds ratios (OR) for CAs, together with their 95% confidence intervals (CIs), adjusting for maternal age, parity, pre-pregnancy body mass index (BMI), and maternal smoking status. RESULTS The risk of major CAs was higher in the GDM-exposed (n = 336, 5.09%) than in the non-exposed group (n = 2,255, 4.33%) (OR: 1.18, 95% CI: 1.05-1.33, p = 0.005). The adjusted OR (aOR) was 1.14 (95% CI: 1.00-1.30, p = 0.047). There was a higher overall prevalence of CAs, particularly chromosomal abnormalities (0.52% vs. 0.21%), in the GDM-exposed group (OR: 2.49, 95% Cl: 1.69-3.66, p < 0.001). The aOR was 1.93 (95% Cl: 1.25-2.99, p = 0.003). CONCLUSIONS Offspring exposed to GDM have a higher prevalence of major CAs. Of note, risk factors other than GDM, such as older maternal age and a higher pre-pregnancy BMI, diminished the between group differences in the prevalence of major CAs. Nevertheless, our findings suggest that offspring exposed to maternal GDM are more likely to be diagnosed with a chromosomal abnormality, independent of maternal age, parity, pre-pregnancy BMI, and smoking.

Associations of low sex hormone-binding globulin and androgen excess in early pregnancy with fasting and post-prandial hyperglycaemia, gestational diabetes, and its severity. Diabetes Metab Res Rev 2023; 39:e3599. [PMID: 36484476 PMCID: PMC10078580 DOI: 10.1002/dmrr.3599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Revised: 10/07/2022] [Accepted: 11/10/2022] [Indexed: 12/13/2022]
Abstract
AIMS We studied whether androgen excess and low sex hormone-binding globulin (SHBG) measured in early pregnancy are independently associated with fasting and post-prandial hyperglycaemia, gestational diabetes (GDM), and its severity. MATERIALS AND METHODS This nationwide case-control study included 1045 women with GDM and 963 non-diabetic pregnant controls. We measured testosterone (T) and SHBG from biobanked serum samples (mean 10.7 gestational weeks) and calculated the free androgen index (FAI). We first studied their associations with GDM and secondly with the type of hyperglycaemia (fasting, 1 and 2 h glucose concentrations during the oral glucose tolerance test), early-onset GDM (<20 gestational weeks) and the need for anti-diabetic medication. RESULTS After adjustments for gestational weeks at sampling, pre-pregnancy BMI, and age, women with GDM had 3.7% (95% CI 0.1%-7.3%) lower SHBG levels, 3.1% (95% CI 0.1%-6.2%) higher T levels, and 4.6% (95% CI 1.9%-7.3%) higher FAI levels than controls. SHBG was inversely associated with fasting glucose, whereas higher FAI and T were associated with higher post-prandial glucose concentrations. Women with early-onset GDM had 6.7% (95% CI 0.7%-12.7%) lower SHBG levels and women who needed insulin for fasting hyperglycaemia 8.7% (95% CI 1.8%-14.8%) lower SHBG levels than other women with GDM. CONCLUSIONS Lower SHBG levels were associated especially with early-onset GDM, higher fasting glucose and insulin treatment, whereas androgen excess was associated with higher post-prandial glucose values. Thus, a low SHBG level may reflect the degree of existing insulin resistance, while androgen excess might impair post-prandial insulin secretion.

Increased Oral Care Needs and Third Molar Symptoms in Women with Gestational Diabetes Mellitus: A Finnish Gestational Diabetes Case-Control Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:10711. [PMID: 36078430 PMCID: PMC9518339 DOI: 10.3390/ijerph191710711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 08/13/2022] [Accepted: 08/24/2022] [Indexed: 06/15/2023]
Abstract
(1) Hyperglycemia and oral pathology accelerate each other in diabetes. We evaluated whether gestational diabetes mellitus (GDM) is associated with self-reported increased oral health care needs and oral symptoms, including third molar symptoms, during pregnancy. (2) Pregnant women with (n = 1030) and without GDM (n = 935) were recruited in this multicenter Finnish Gestational Diabetes study in 2009-2012. Of the women with GDM, 196 (19.0%) receiving pharmacological treatment, 797 (77.0%) receiving diet treatment and 233 (23.0%) with recurrent GDM were analyzed separately. Oral health was assessed using structured questionnaires and analyzed by multivariable logistic regression adjusted for background risk factors. (3) Women with GDM were more likely to report a higher need for oral care than controls (31.1% vs. 24.5%; odds ratio (OR) 1.39; 95% confidence interval (CI) 1.14-1.69), particularly women with recurrent GDM (38.1% vs. 24.5%; OR 1.90; 95% CI 1.40-2.58). Women with pharmacologically treated GDM (46.9%) more often had third molar symptoms than controls (36.1%; OR 1.57; 95% CI 1.15-2.15) than women with diet-treated GDM (38.0%; OR 1.47; 95% CI 1.07-2.02). (4) GDM is associated with perceived oral care needs. Third molar symptoms were associated with pharmacologically treated GDM.

Abstract
Sociocultural gender is a complex construct encompassing different aspects of individuals' life, whereas sex refers to biological factors. These terms are often misused, although they impact differently on individuals' health. Recognizing the role of sex and gender on health status is fundamental in the pursuit of a personalized medicine. Aim of the current study was to investigate the awareness in approaching clinical and research questions on the impact of sex and gender on health among European internists. Clinicians affiliated with the European Federation of Internal Medicine from 33 countries participated to the study on a voluntary basis between January 1st, 2018 and July 31st, 2019. Internists' awareness and knowledge on sex and gender issues in clinical medicine were measured by an online anonymized 7-item survey. A total of 1323 European internists responded to the survey of which 57% were women, mostly young or middle-aged (78%), and practicing in public general medicine services (74.5%). The majority (79%) recognized that sex and gender are not interchangeable terms, though a wide discrepancy exists on what clinicians think sex and gender concepts incorporate. Biological sex and sociocultural gender were recognized as determinants of health mainly in cardiovascular and autoimmune/rheumatic diseases. Up to 80% of respondents acknowledged the low participation of female individuals in trials and more than 60% the lack of sex-specific clinical guidelines. Internists also express the willingness of getting more knowledge on the impact of sex and gender in cerebrovascular/cognitive and inflammatory bowel diseases. Biological sex and sociocultural gender are factors influencing health and disease. Although awareness and knowledge remain suboptimal across European internists, most acknowledge the underrepresentation of female subjects in trials, the lack of sex-specific guidelines and the need of being more informed on sex and gender-based differences in diseases.

Normal Gestational Weight Gain Protects From Large-for-Gestational-Age Birth Among Women With Obesity and Gestational Diabetes. Front Public Health 2021; 9:550860. [PMID: 34136447 PMCID: PMC8200493 DOI: 10.3389/fpubh.2021.550860] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Accepted: 05/07/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Pre-pregnancy obesity, excess gestational weight gain (GWG), and gestational diabetes (GDM) increase fetal growth. Our aim was to assess whether normal GWG is associated with lower risk for a large-for-gestational-age (LGA; over the 90th percentile of birth weight for sex and gestational age) infant and lower birth weight standard deviation (SD) score in the presence of GDM and maternal obesity. Methods: This multicenter case-control study is part of the Finnish Gestational Diabetes (FinnGeDi) Study and includes singleton pregnancies of 1,055 women with GDM and 1,032 non-diabetic controls. Women were divided into 12 subgroups according to their GDM status, pre-pregnancy body mass index (BMI; kg/m2), and GWG. Non-diabetic women with normal BMI and normal GWG (according to Institute of Medicine recommendations) served as a reference group. Results: The prevalence of LGA birth was 12.2% among women with GDM and 6.2% among non-diabetic women (p < 0.001). Among all women, normal GWG was associated with lower odds of LGA [odds ratio (OR) 0.57, 95% CI: 0.41–0.78]. Among women with both obesity and GDM, the odds for giving birth to a LGA infant was 2.25-fold (95% CI: 1.04–4.85) among those with normal GWG and 7.63-fold (95% CI: 4.25–13.7) among those with excess GWG compared with the reference group. Compared with excess GWG, normal GWG was associated with 0.71 SD (95% CI: 0.47–0.97) lower birth weight SD score among women with GDM and obesity. Newborns of normal weight women with GDM and normal GWG had 0.28 SD (95% CI: 0.05–0.51) lower birth weight SD scores compared with their counterparts with excess GWG. In addition, in the group of normal weight non-diabetic women, normal GWG was associated with 0.46 SD (95% CI: 0.30–0.61) lower birth weight SD scores compared with excess GWG. Conclusion: GDM, obesity, and excess GWG are associated with higher risk for LGA infants. Interventions aiming at normal GWG have the potential to lower LGA rate and birth weight SD scores even when GDM and obesity are present.

Abstract
BACKGROUND Severe early onset (less than 34 weeks gestation) intrahepatic cholestasis of pregnancy (ICP) affects 0.1% of pregnant women in Australia and is associated with a 3-fold increased risk of stillbirth, fetal hypoxia and compromise, spontaneous preterm birth, as well as increased frequencies of pre-eclampsia and gestational diabetes. ICP is often familial and overlaps with other cholestatic disorders. Treatment options for ICP are not well established, although there are limited data to support the use of ursodeoxycholic acid (UDCA) to relieve pruritus, the main symptom. Rifampicin, a widely used antibiotic including in pregnant women, is effective in reducing pruritus in non-pregnancy cholestasis and has been used as a supplement to UDCA in severe ICP. Many women with ICP are electively delivered preterm, although there are no randomised data to support this approach. METHODS We have initiated an international multicentre randomised clinical trial to compare the clinical efficacy of rifampicin tablets (300 mg bd) with that of UDCA tablets (up to 2000 mg daily) in reducing pruritus in women with ICP, using visual pruritus scores as a measuring tool. DISCUSSION Our study will be the first to examine the outcomes of treatment specifically in the severe early onset form of ICP, comparing "standard" UDCA therapy with rifampicin, and so be able to provide for the first-time high-quality evidence for use of rifampicin in severe ICP. It will also allow an assessment of feasibility of a future trial to test whether elective early delivery in severe ICP is beneficial.

Abstract
The current classification of hypertension does not reflect the heterogeneity in characteristics or cardiovascular outcomes of hypertensive individuals. Our objective was to identify distinct phenotypes of hypertensive individuals with potentially different cardiovascular risk profiles using data-driven cluster analysis. We performed clustering, a procedure that identifies groups with similar characteristics, in 3726 individuals (mean age 59.4 years, 49% women) with grade 2 hypertension (blood pressure ≥160/100 mmHg or antihypertensive medication) selected from FINRISK 1997, 2002, and 2007 cohorts. We computed clusters based on eight factors associated with hypertension: mean arterial pressure, pulse pressure, non-high-density lipoprotein cholesterol, blood glucose, BMI, C-reactive protein, estimated glomerular filtration rate, and alcohol. After that, we used Cox regression models adjusted for age and sex to assess the relative risk of cardiovascular disease (CVD) outcomes between the clusters and a reference group of 11 020 individuals. We observed two comparable clusters in both men and women. The Metabolically Challenged (MC) cluster was characterized by high blood glucose (Z-score 4.4 ± 1.1 vs 0.2 ± 0.8, men; 3.5 ± 1.1 vs 0.0 ± 0.6, women) and elevated BMI (30.4 ± 4.1 vs 28.9 ± 4.3, men; 32.7 ± 4.9 vs 29.3 ± 5.5, women). Over a 10-year follow-up (1034 CVD events), MC had 1.6-fold (95% CI 1.1-2.4) CVD risk compared to non-MC and 2.5-fold (95% CI 1.7-3.7) CVD risk compared to the reference group (P ≤ .009 for both). Using unsupervised hierarchical clustering, we found two phenotypically distinct hypertension subgroups with different risks of CVD complications. This substratification could be used to design studies that explore the differential effects of antihypertensive therapies among subgroups of hypertensive individuals.

Abstract
Objective To assess the frequency and perinatal outcomes of gestational diabetes mellitus (GDM) defined by the criteria according to the International Association of Diabetes in Pregnancy Study Group (IADPSG) and the National Institute for Health and Care Excellence (NICE) diagnostic criteria for GDM. Design A retrospective cohort study. Setting Six secondary and tertiary delivery hospitals in Finland in 2009. Population Pregnant women (N = 4,033) and their offspring. Methods We used data on comprehensive screening of pregnant women with a 2-h 75-g oral glucose tolerance test (OGTT), performed between gestational weeks 24 and 40. OGTT glucose concentrations were used to identify women who fulfilled IADPSG and NICE criteria. While cut-offs according to Finnish national criteria partly overlapped with both criteria, a subgroup of IADPSG- or NICE-positive GDM women remained undiagnosed by Finnish criteria and hence non-treated. They were analysed as subgroups and compared to controls who were negative with all cut-offs. Main outcome measures GDM prevalence, birth weight SD score (BWSDS), large for gestational age (LGA) and caesarean section (CS) rates. Results Among the 4,033 women screened for GDM, 1,249 (31.0%) and 529 (13.1%) had GDM according to the IADPSG and NICE criteria, respectively. The LGA rate was similar in both groups. Regardless of the diagnostic criteria, women with GDM had a higher risk of induced delivery and CSs than controls. In IADPSG-positive non-treated women, offspring’s BWSDS and CS rate were higher than in controls. Conclusions GDM prevalence was 2.4-fold higher according to the IADPSG compared with the NICE criteria but the LGA rate did not differ. BWSDS and CS rate were increased already with mild untreated hyperglycaemia.

Abstract
Background To determine the risk of cesarean delivery after labor induction among patients with prior placenta-mediated pregnancy complications (pre-eclampsia, late pregnancy loss, placental abruption or intrauterine growth restriction). Methods The AFFIRM database includes patient level data from 9 randomized controlled trials that evaluated the role of LMWH versus no LMWH during pregnancy to prevent recurrent placenta-mediated pregnancy complications. The primary outcome of this sub-study was the proportion of women who had an unplanned cesarean delivery after induction of labor compared to after spontaneous labor. Results There were 512 patients from 7 randomized trials included in our sub-study. There was no difference in the risk of cesarean delivery between women with labor induction (21/148, 14.2%) and spontaneous labor (79/364, 21.7%) (odds ratio (OR) 0.60, 95% CI, 0.35–1.01; p = 0.052). Among 274 women who used LMWH prophylaxis during pregnancy, the risk of cesarean delivery was lower among those that underwent labor induction (9.8%) compared to spontaneous labor (22.4%) (OR 0.38, 95% CI, 0.17–0.84; p = 0.01). Conclusions The risk of cesarean delivery is not increased after labor induction among a higher risk patient population with prior pregnancy complications. Our results suggest that women who receive LMWH during pregnancy might benefit from labor induction.

Abstract
Abstract
Background
Indoleamine 2,3-dioxygenase (IDO) is an intracellular enzyme that has an important immunomodulator function. Human inflammatory response promotes upregulation of IDO level in blood. This may lead to suppression of inflammation in atherosclerotic vessel wall and consequently may slow the progression of the disease. Previous studies have shown that IDO activity correlates with early signs of atherosclerosis especially in females but is not an atherosclerosis-specific marker.
Materials and methods
IDO levels were measured from females (n=544; age 24–39; weight 40.5–134.4 kg) in 2001 along with several risk factors for atherosclerosis. Follow-up risk factor measurements were performed in 2007 and 2011. Here we aimed to elucidate the relationship between IDO measurements from 2001 and several atherosclerotic risk factors from 2007 and 2011 by analyzing correlations and risk ratios from the Cardiovascular Risk in Young Finns Study patient cohort.
Results
After age standardization, IDO correlated significantly with BMI (p=0.0008), waist (p=0.0009) and logarithmically modified triglycerides (p=0.0488) and CRP (p=0.0014) in female samples (n=434) from 2007. When female samples (n=384) from 2011 were examined, statistically significant correlations were discovered in BMI and Waist in both unadjusted (p<0.0001 and 0.0003, respectively) and age-adjusted analysis (p=0.0007 and 0.006, respectively). In contrast, only weak correlations were found in male samples. In risk ratio analysis IDO promoted obesity (RR=1.027, p=0.01) in females (n=431) in 10-year follow-up study even after the data was adjusted for age, CRP and BMI.
Conclusions
It is concluded that IDO activity forecasts obesity – a well-characterized risk factor for diabetes and atherosclerosis – in premenopausal females.

In a randomised open study, 44 pregnant women with confirmed previous or current thromboembolism were randomised to receive either low-molecular-weight heparin, dalteparin (N = 21) once daily subcutaneously or unfractionated sodium heparin (UF heparin, N = 23) twice daily subcutaneously for thromboprophylaxis during pregnancy and puerperium. Bone mineral density (BMD) in the lumbosacral spine was measured with dual X-ray absorptiometry (DEXA) 1, 6, 16, 52 weeks and, if possible, 3 years after delivery. BMD values were also compared with those of healthy, delivered women (N =19).Mean BMD of the lumbar spine was significantly lower in the unfractionated heparin group compared with the dalteparin and with the control groups (repeated measures ANOVA p = 0.02). BMD in the dalteparin group did not differ from BMD of healthy delivered women. Multiple logistic regression analysis revealed that therapy was the only independent factor influencing BMD at weeks 16 and 52. Therefore we recommend use of dalteparin instead of UF heparin for long-term thromboprophylaxis during and after pregnancy.

Abstract
AIMS/HYPOTHESIS The aim of this study was to explore the association between type 1 diabetes and reproductive health indicators in women, focusing on termination of pregnancy and sterilisation. METHODS We conducted a registry-based cohort study involving 2281 women with childhood-onset type 1 diabetes, matched for age and birthplace with women without diabetes: two control participants for each woman with diabetes. We compared the frequencies of termination of pregnancy and sterilisation over a 25 year period between women with type 1 diabetes and women without, and estimated standardised incidence ratios (SIRs). Smoothed age and period effects in the incidence of termination of pregnancy or sterilisation were tested statistically. RESULTS There were more terminations of pregnancy (SIR 1.67; 95% CI 1.51, 1.86) and sterilisations (SIR 1.69; 95% CI 1.56, 1.83) in women with diabetes than in control women. During recent years, sterilisations in women with diabetes have decreased and the difference compared with control women has vanished. The indications for both procedures showed a statistically highly significant difference: maternal medical indications were almost absent (< 1%) in procedures among control women, but comprised 23.6% of terminations of pregnancy and 22.9% of sterilisations in women with diabetes. CONCLUSIONS/INTERPRETATION The indications for termination of pregnancy and sterilisation are different in women with diabetes compared with other women. Pregnancies in women with type 1 diabetes are still terminated more often than in women without diabetes, but the difference in sterilisation rates has disappeared during recent years.

Abstract
SummaryThrombin regulation in newborns remains incompletely understood.We studied tissue factor-initiated thrombin formation in cord plasma in vitro, and the effects of Factor VLeiden (FVL) heterozygosity on thrombin regulation both in vitro and in vivo in newborns. Pregnant women with known thrombophilia (n=27) were enrolled in the study. Cord blood and venous blood at the age of 14 days were collected from 11 FVL heterozygous newborns (FVL-positive) and from 16 FVL-negative newborns. Prothrombin fragment F1+2 and coagulation factors were measured. Tissue factor-initiated thrombin formation was studied in cord platelet-poor plasma (PPP) of FVL-negative and -positive newborns, and in both PPP and platelet-rich plasma (PRP) of healthy controls. The endogenous thrombin potential (ETP) in cord PPP or PRP was ∼60% of that in adult plasma, while thrombin formation started ∼55% and ∼40% earlier in cord PPP and PRP, respectively. Further, in FVL-positive newborns thrombin formation started significantly earlier than in FVL-negative newborns. Exogenous activated protein C (APC) decreased ETP significantly more in cord than in adult PRP. In FVL-negative cord plasma 5nM APC decreased ETP by 17.4±3.5% (mean±SEM) compared with only 3.5±3.8% in FVL-positive cord plasma (p=0.01). FVL-positive newborns showed similar levels of F1+2 but significantly decreased levels of factor V compared with FVL negative newborns both in cord plasma (FV 0.82±0.07 U/ml vs. 0.98±0.05 U/ml, p=0.03) and at the age of two weeks (FV 1.15±0.04 U/ml vs. 1.32±0.05 U/ml, p=0.03). In conclusion, newborn plasma showed more rapid thrombin formation and enhanced sensitivity to APC compared with adult plasma. FVL conveyed APC resistance and a procoagulant effect in newborn plasma. Lack of elevated F1+2 levels in FVL-positive infants, however, suggested the existence of balancing mechanisms; one could be the observed lower level of factor V in FVL heterozygous newborns.

Abstract
BACKGROUND Placenta-mediated pregnancy complications include pre-eclampsia, late pregnancy loss, placental abruption, and birth of a small-for-gestational-age (SGA) neonate. These complications are leading causes of maternal, fetal, and neonatal morbidity and mortality in high-income countries. Affected women are at high risk of recurrence in subsequent pregnancies; however, effective strategies to prevent recurrence are absent. Findings from our previous study-level meta-analysis suggested that low-molecular-weight heparin reduced the risk of recurrent placenta-mediated pregnancy complications. However, we identified significant heterogeneity in the results, possibly due to trial design or inclusion criteria. To identify which patients benefit from, and which outcomes are prevented by, low-molecular-weight heparin, we did an individual patient data meta-analysis. METHODS We did a systematic review in May, 2013, which identified eight eligible randomised trials done between 2000 and 2013 of low-molecular-weight heparin to prevent recurrent placenta-mediated pregnancy complications. We excluded studies on the basis of the wrong population, the study being ongoing, inability to confirm eligibility of participants, intervention stopped too early, and no response from the principal investigator. We requested individual patient data from the study authors for eligible women (women pregnant at the time of the study with a history of previous pregnancy that had been complicated by one or more of the following: pre-eclampsia, placental abruption, birth of an SGA neonate [<10th percentile], pregnancy loss after 16 weeks' gestation, or two losses after 12 weeks' gestation) and recoded, combined, and analysed the data for our meta-analysis. The primary outcome was a composite of early-onset (<34 weeks) or severe pre-eclampsia, birth of an SGA neonate (<5th percentile), late pregnancy loss (≥20 weeks' gestation), or placental abruption leading to delivery, assessed on an intention-to-treat basis. We assessed risk of bias with the Cochrane Risk of Bias tool. This study is registered with PROSPERO, number CRD42013006249. FINDINGS We analysed data from 963 eligible women in eight trials: 480 randomly assigned to low-molecular-weight heparin and 483 randomly assigned to no low-molecular-weight heparin. Overall, the risk of bias was not substantial enough to affect decisions regarding trial inclusion. Participants were mostly white (795/905; 88%) with a mean age of 30·9 years (SD 5·0) and 403/963 (42%) had thrombophilia. In the primary analysis, low-molecular-weight heparin did not significantly reduce the risk of recurrent placenta-mediated pregnancy complications (low-molecular-weight heparin 62/444 [14%] versus no low-molecular-weight heparin 95/443 (22%) absolute difference -8%, 95% CI -17·3 to 1·4, p=0·09; relative risk 0·64, 95% CI 0·36-1·11, p=0·11). We noted significant heterogeneity between single-centre and multicentre trials. In subgroup analyses, low-molecular-weight heparin in multicentre trials reduced the primary outcome in women with previous abruption (p=0·006) but not in any of the other subgroups of previous complications. INTERPRETATION Low-molecular-weight heparin does not seem to reduce the risk of recurrent placenta-mediated pregnancy complications in at-risk women. However, some decreases in event rates might have been too small for the power of our study to explore. FUNDING Canadian Institutes of Health Research.

Abstract
AIMS This study aims to assess the association between parity and mortality in adults with childhood-onset type 1 diabetes (T1D) and their matched controls. METHODS Individual data (308 617 person-years) on mortality and the reproductive histories of a Finnish cohort of 2307 women and 2819 men with T1D, each with two matched controls, were obtained from the National Population Register. All persons with diabetes had been diagnosed with T1D in 1965-1979 at the age of 17 or under. RESULTS All-cause mortality in people without offspring was significantly higher than that in people with children among both people with diabetes and non-diabetic control persons in both sexes (all p-values <0.01). In men with offspring, the decrease of mortality rate compared with men without offspring was less marked among those with diabetes (9% reduction in mortality hazard ratio (HR) with one offspring, 47% with two) than among those without diabetes (33% HR (p = 0.025) and 61% HR (p = 0.023) reduction, respectively). In women with offspring, the association between parity and mortality was independent of diabetes status. Having at least two offspring was associated with a decreased hazard of diabetes-related death regardless of sex; among women with diabetes, even having one offspring was associated with a decreased hazard of dying from diabetes (HR = 0.46; 95% CI 0.31, 0.69). CONCLUSIONS The association between parity and mortality follows different patterns in men and women with T1D. To what extent this reflects effects of health on family planning decisions in people with T1D cannot be defined without further studies. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
OBJECTIVE Adiponectin is an adipocyte-derived protein with profound insulin-sensitizing, anti-inflammatory, and antiatherogenic effects. Surprisingly, recent evidence suggests that adiponectin concentrations are increased during preeclampsia, which is characterized by insulin resistance. We studied whether serum adiponectin is related to insulin sensitivity in preeclamptic and normotensive pregnant women. METHODS We measured serum adiponectin concentrations and insulin sensitivity (intravenous glucose tolerance test/minimal model) in 22 women with preeclampsia and 15 normotensive controls with similar pre-pregnancy body mass index (BMI) (range 18-29 kg/m(2)) between 29 and 39 weeks of gestation. Fourteen cases and 10 controls were also studied 6-22 weeks after delivery. No subject had gestational diabetes. RESULTS During pregnancy, the mean adiponectin concentration in preeclamptic women was 10.3 (SD 4.2) mug/mL as compared to 7.9 (SD 2.9) microg/mL in normotensive controls (95% confidence interval [CI] for difference 0.1-5.3 microg/mL; P = .04). Adiponectin concentrations were unrelated to insulin sensitivity both in preeclamptic and normotensive subjects; insulin sensitivity was decreased in preeclampsia (P = .01). After delivery, mean adiponectin concentration was lower than during pregnancy: 7.4 (SD 3.0) microg/mL in preeclamptic subjects (P = .001) and 7.1 (SD 1.6) microg/mL in normotensive controls (P = .06) and similar in cases and controls (95% CI for difference -1.7-2.3 microg/mL, P = .7). CONCLUSIONS Despite their reduced insulin sensitivity, preeclamptic women have higher adiponectin concentrations than normotensive pregnant women. These concentrations are unrelated to insulin sensitivity. After pregnancy, the difference in adiponectin concentrations is no longer present between the two groups. These findings are consistent with a role of adiponectin in the pathophysiology of preeclampsia.

Abstract
The presence of antiphospholipid antibodies is associated with thromboembolic events, thrombocytopenia and numerous pregnancy complications such as recurrent miscarriage, preeclampsia and HELLP syndrome. This condition is known as the antiphospholipid syndrome (APS). We describe a rare case of recurrent liver necrosis postpartum in two consecutive pregnancies of woman with systemic lupus erythematosus (SLE) and positive antiphospholipid antibodies (aPL) who underwent complete recovery.

Abstract
Progression of retinopathy and nephropathy in women with diabetes occurs, at least temporarily, during pregnancy and postpartum. However, normotensive pregnancy seems to have no detrimental effects regarding the long-term progression of any microvascular complication. Increased risk from pregnancy induced hypertension without proteinuria and with proteinuria (pre-eclampsia) relates mainly to the association with kidney disease in diabetes, and poor glycemic control. A history of pre-eclampsia or pregnancy induced hypertension is an important prognostic factor for micro- and macro-vascular complications later in life. Data regarding the long-term effects of hypertensive pregnancies on late complications of diabetes suggest that women with diabetes should be monitored regularly and nephroprotective treatment initiated early.

Abstract
AIMS The aim of this study is to find factors associated with metabolic syndrome in obese individuals and thus offer guidance to stay metabolically healthy if obese. METHODS A cardiovascular screening programme performed in Finland during the years 2005-2007, identified 901 obese white individuals. Of them, 269 (30%) were metabolically healthy according to the Harmonization criteria of metabolic syndrome. RESULTS In multivariate logistic regression analysis, male sex [odds ratio (OR) 1.44 (95% CI 1.01-2.07)], living alone [OR 1.77 (95% CI 1.18-2.65)], physical inactivity [OR 3.73 (95% CI 1.24-11.24)], and use of betablockers [OR 2.63 (95% CI 1.75-3.95)] were associated with metabolic syndrome. CONCLUSIONS Even mild or occasional physical exercise is beneficial to health in obese individuals. Betablockers may not be the antihypertensive agents of choice when treating obese hypertensive individuals.

Abstract
Diabetic women carry a 2-4 times increased risk of a hypertensive pregnancy compared to non-diabetic people. This risk is related to presence of diabetic nephropathy, but also poor glycaemic control. Efforts to improve glycaemic control have decreased perinatal morbidity and mortality related to diabetic nephropathy. Despite good glycaemic control, overt nephropathy is associated with a variety of pregnancy complications, such as fetal growth restriction and pre-eclampsia. General population studies show that women with a history of pre-eclampsia are more prone to develop cardiovascular disease later in life than women with a history of normotensive pregnancy. Furthermore, recent data regarding the long-term effects of hypertensive pregnancies on late diabetic complications indicate that these women should be followed and treatment should be started early. In this review we summarize data on risk factors and long-term effects of hypertensive pregnancies on late diabetic complications that may be of clinical relevance in the prevention of these complications.
