Background: Chronic obstructive pulmonary disease (COPD) is a common disease with considerable consequences for patients' daily lives. The Clinical COPD Questionnaire (CCQ) was designed to measure these consequences in daily practice. Although the CCQ is widely used, its original structure has never been tested., Aims: This study examines the psychometric properties of the CCQ with regard to its latent structure in a sample of primary care patients with COPD., Methods: Two cross-sectional studies were conducted; in study 1 (N=243) exploratory analyses, including exploratory factor analysis (EFA) and Mokken scale analysis, were performed to explore the latent structure of the CCQ. In study 2 (N=244), confirmatory factor analysis (CFA) was conducted to evaluate the model fit of the structure found in study 1., Results: Both EFA and Mokken scale analysis revealed a structure of two dimensions ('general impact' α=0.91 and 'cough' α=0.84). This structure, however, was not confirmed in study 2, nor was the original structure. However, subsequently removing items that violated the assumption of a normal response distribution did result in an excellent model fit with two dimensions measuring 'dyspnoea' and 'cough' (CFA: comparative fit index (CFI) 0.98; normed fit index (NFI) 0.97; root mean squared error of approximation (RMSEA) 0.08 (0.04))., Conclusions: In primary care, factor analyses on the CCQ revealed a two-component structure measuring 'general impact', and 'cough'. A shortened and more specific version of the CCQ could be regarded as a useful instrument to screen for exacerbations by measuring dyspnoea, coughing and producing phlegm.

Background: Maternal thyroid dysfunction is of known influence on pregnancies in the preterm period. However little is known about its effect on term and post term pregnancies. Meconium stained amniotic fluid (MSAF) is known to occur preferentially in (post)term pregnancies., Aims: To assess a possible independent relation between maternal thyroid function and MSAF., Study Design and Subjects: 1051 women, in whom thyroid function was assessed at each trimester, were followed prospectively (delivery ≥37weeks). We compared the difference in mean TSH and FT4 between women with (152) and without (899) MSAF using one way ANOVA. Thyroid function was assessed in subgroups regarding gestational age. Finally we performed multiple logistic regression analysis with MSAF as dependent variable and TSH as independent variable adjusting for various confounders., Results: Maternal thyroid function was not associated with the incidence of MSAF when analysing all deliveries ≥37weeks. However, in the "at-risk" group for MSAF (>41weeks), multiple logistic regression showed an independent relation between MSAF and TSH (O.R.: 1.61, 95% CI: 1.10-2.43)., Conclusions: The present study shows that in women delivering ≥41weeks of gestation, higher TSH is independently related to MSAF., (Copyright © 2014 Elsevier Ltd.

Objective: The DiaMind trial showed beneficial immediate effects of mindfulness-based cognitive therapy (MBCT) on emotional distress, but not on diabetes distress and HbA1c. The aim of the present report was to examine if the effects would be sustained after six month follow-up., Methods: In the DiaMind trial, 139 outpatients with diabetes (type-I or type-II) and a lowered level of emotional well-being were randomized into MBCT (n=70) or a waiting list with treatment as usual (TAU: n=69). Primary outcomes were perceived stress, anxiety and depressive symptoms, and diabetes distress. Secondary outcomes were, among others, health status, and glycemic control (HbA1c)., Results: Compared to TAU, MBCT showed sustained reductions at follow-up in perceived stress (p<.001, d=.76), anxiety (p<.001, assessed by HADS d=.83; assessed by POMS d=.92), and HADS depressive symptoms (p=.004, d=.51), but not POMS depressive symptoms when using Bonferroni correction for multiple testing (p=.016, d=.48). No significant between-group effect was found on diabetes distress and HbA1c., Conclusion: This study showed sustained benefits of MBCT six months after the intervention on emotional distress in people with diabetes and a lowered level of emotional well-being., Trial Registration: Dutch Trial Register NTR2145, http://www.trialregister.nl., (Copyright © 2014 Elsevier Inc.

Background and Objectives: Previous findings regarding a possible association between beta-blocker use and depression are mixed. To our knowledge there have been no studies investigating the association of beta-blockers with depression in primary care hypertension patients without previous myocardial infarction. The aim of this study was to determine the relation between lipophilic beta-blocker use and depression in elderly primary care patients with hypertension., Methods: This was a cross-sectional study in primary care practices located in the South of The Netherlands. Primary care hypertension patients without previous myocardial infarction or heart failure (n=573), aged between 60 and 85 years (mean age=70±6.6), were included. All patients underwent a structured interview that included a self-report questionnaire to assess depression (PHQ-9), which was divided in four groups (PHQ-9 score of 0, 1--3, 4--8, 9 or higher)., Results: A PHQ-9 score of 0 was more prevalent in non-beta-blocker users versus lipophilic beta-blocker users (46% versus 35%), a PHQ-9 score of 4--8 was less prevalent in non-beta-blocker users as compared with lipophilic beta-blocker users (14% versus 25%). A chi-squared test showed that lipophilic beta-blocker users as compared to non-beta-blockers users were more likely to be in a higher depression category. Ordinal regression showed a significant relationship between use of lipophilic beta-blockers and depression (OR=1.60, 95% CI=1.08--2.36) when adjusting for potential confounders., Conclusions: Our findings show that primary care hypertension patients who use a lipophilic beta-blocker are more likely to have higher depression scores than those who do not use a lipophilic beta-blocker.

Background: The prevalence and diagnostic value of heart failure symptoms in elderly primary care patients with hypertension is unknown., Aim: To assess the prevalence, sensitivity, specificity, positive and negative predictive value of symptoms in association with an abnormal echocardiogram., Design and Setting: Cross-sectional screening study in five general practices in the south-east of the Netherlands., Method: Between June 2010 and January 2013, 591 primary care hypertension patients aged between 60 and 85 years were included, without known heart failure and not treated by a cardiologist. All patients underwent an echocardiogram and a structured interview including assessment of heart failure symptoms: shortness of breath, fatigue, oedema, cold extremities, and restless sleep., Results and Conclusion: Restless sleep was reported by 25 %, cold extremities by 23 %, fatigue by 19 %, shortness of breath by 17 %, and oedema by 13 %. Oedema was the only symptom significantly associated with an abnormal echocardiogram (positive predictive value was 45 %, sensitivity 20 %, and specificity 90 %, OR 2.12; 95 % CI = 1.23-3.64), apart from higher age (OR 1.06; 95 % CI = 1.03-1.09), previous myocardial infarction (OR 3.00; 95 % CI = 1.28-7.03), and a systolic blood pressure of >160 mmHg (OR 1.62; 95 % CI = 1.08-2.41). Screening with echocardiography might be considered in patients with oedema.

Background: Identification of cardio-toxic psychological symptoms in coronary artery disease (CAD) patients is important., Purpose: We examined the association of negative affectivity (NA), social inhibition (SI), and their combination in the distressed (Type D) personality with functional status, fatigue, and mental distress in CAD patients., Method: Following acute coronary syndrome, 690 consecutive CAD patients agreed to participate in this cross-sectional study and were evaluated for clinical characteristics, including left ventricular ejection fraction (LVEF), and for NA, SI, and Type D personality (i.e., NA and SI; DS14 scale) when they entered a cardiac rehabilitation program in Lithuania. Patient-centered outcomes included functional status (bicycle ergometer), symptoms of fatigue (Multidimensional Fatigue Inventory-20), and mental distress (Beck Depression Inventory-II and Hospital Anxiety and Depression Scale)., Results: The reference subgroup (neither NA nor SI) included 34 % of patients; 13 % had NA only, 19 % had SI only, and 34 % had Type D profile. Type D patients had worse functional status, and Type D patients and NA-only patients had higher symptom levels of fatigue and mental distress. In multivariate regression models that included LVEF, clinical characteristics, and depressive symptoms, Type D personality was an independent predictor of decreased exercise capacity (OR = 1.77, 95 % CI 1.06-2.95, p = .03) and decreased motivation for activity (OR = 3.14, 95 % CI 1.73-5.73, p < .001). Type D, NA, and SI were also independent predictors of mental distress., Conclusions: Type D personality traits independently predicted poor functional status and worse patient-centered outcomes independently from LVEF and depression. Further studies exploring personality-related differences in cardiovascular outcomes are needed.

Background: Excercise self-efficacy is believed to influence physical activity bahavior., Purpose: The purpose of this study is to assess the psychometric aspects of the Exercise Self-efficacy Scale (ESS) in a type 2 diabetes Dutch Primary care sample., Method: Type 2 diabetes patients (n = 322; <80 years old) filled in the ESS and the short questionnaire to assess health enhancing physical activity (SQUASH). The structural validity of the ESS was assessed by means of principal axis factor analyses and confirmatory factor analysis. In addition, reliability and concurrent validity with the SQUASH outcomes "total" and "leisure time minutes/week of moderate to vigorous intensity physical activity" were evaluated. T tests and ANOVAs were used to examine ESS scores in subgroups. In addition, a 13-item version of the ESS was developed., Results: Analyses were performed on complete cases (n = 255). Exploratory factor analysis suggested one underlying factor (total explained variance 54 %), with good internal consistency (α = 0.95). Confirmatory factor analysis showed a poor fit, as did a three-factor model suggested in an earlier research. Therefore, a 13-item ESS was developed with one underlying factor (total explained variance 59 %) and good internal consistency (α = 0.95). Both the 18-item and 13-item ESS correlated significantly with total and leisure time physical activity. ESS scores differed significantly between categories of education level and physical activity level., Conclusion: The 13-item ESS had sound psychometric properties in a large sample of primary care type 2 diabetes patients. The 13-item ESS could be useful in (intervention) research on physical activity in type 2 diabetes patients.

Background: Objective was to determine whether fear for external cephalic version (ECV) and depression are associated with the success rate of ECV in women with a breech presentation at term., Methods: Prospective study conducted in the Catharina Hospital Eindhoven between October 2007 and May 2012. Participants fulfilled The Edinburgh Depression Scale (EDS) questionnaire and expressed their degree of fear on a visual analogue scale from one to ten before ECV. Obstetric factors were evaluated as well. Primary outcome was the relation between psychological factors (fear for ECV and depression EDS scores) and ECV success rate. Secondary outcome was a possible relation between fear for ECV and increased abdominal muscle tension., Results: The overall success rate was 55% and was significantly lower (p < 0.001) in nulliparous women (44.3%) compared with parous women (78.0%). Fear for ECV and depression EDS-scores were not related with ECV success rate. Parity, placental location, BMI and engagement of the fetal breech were obstetric factors associated with ECV outcome. There was no relation between fear for ECV and abdominal muscle tone., Conclusion: Fear for ECV and depression were not related with ECV success rate in this study. Engagement of the fetal breech was the most important factor associated with a successful ECV., Trial Registration Ebis: The Eindhoven Breech Intervention Study, NCT00516555.

Objective: To develop an instrument to the assess quality of care during pregnancy and delivery as perceived by women who recently gave birth., Study Design: Prospective design from focus group interviews to validation of the questionnaire. The focus groups consisted of seven care providers, ten pregnant women and six women who recently gave birth. With the results of the focus group interviews, a draft questionnaire of 52 items was composed and its psychometric properties were tested in a first cohort of 300 women who recently gave birth (sample I) by means of exploratory factor analysis (EFA) and reliability analysis. The final version was further explored by confirmatory factor analyses (CFA) in another sample of 289 women (sample II) with similar characteristics as sample I., Results: EFA in sample I suggested an 18-item scale with two components concerning the quality of care during pregnancy: 'personal treatment' (11 items, Cronbach's alpha (α)=0.87) and 'educational information' (7 items, α=0.90); the 'delivery' scale showed a single domain (7 items, α=0.88). CFA in sample II confirmed both factor structures with an adequate model fit. Overall, satisfaction with care was highest among women who only received midwife-led care, while women who were referred to an obstetrician during pregnancy reported less satisfaction., Conclusions: The 25-item PCQ, primarily based on the experiences and perceptions of pregnant women and women who recently gave birth, showed adequate psychometric properties evaluating the quality of care during pregnancy and delivery. This user-friendly instrument might be a valuable instrument for future research to further evaluate the quality of care to pregnant women., (Copyright © 2013 Elsevier Ireland Ltd.

Objective: A considerable proportion of pregnant women with a fetus in breech position refuses external cephalic version (ECV), with fear of pain as important barrier. As a consequence, they are at high risk for caesarean section at term. The current study investigated determinants of pain perception during ECV, with special attention to maternal mental state such as depression and fear of ECV., Design: Prospective study of 249 third-trimester pregnant women with breech position with a request for an ECV attempt., Setting: Department of Obstetrics and Gynaecology in a large teaching hospital in the Netherlands., Methods: Prior to the ECV attempts, obstetric factors were registered, participants fulfilled the Edinburgh Depression Scale (EDS) and reported fear of ECV on a 10-point visual analog scale. Perception of pain intensity was measured with a 10-point visual analog scale, immediately after ECV., Findings: Multivariate linear regression analyses showed success of ECV to be the strongest predictor of pain perception. Furthermore, scores on the depression questionnaire and degree of fear of ECV independently explained pain perception, which was not the case for obstetrical or ECV related factors., Conclusion: Apart from ECV outcome, psychological factors like depression and fear of ECV were independently related to pain perception of an ECV attempt., Implication for Practice: Maternal mood state should be taken into account when offering an ECV attempt to women with a fetus in breech position. Due to the painful experience and the importance of successful outcome, ECV should only be attempted in institutions with experienced practitioners and with careful attention to maternal mood and the way a woman is coping with the ECV attempt., (© 2013 Published by Elsevier Ltd.)

Objective: To determine whether thyroid hormone (free thyroxine (fT₄)) rather than TSH is directly related to bone mineral density (BMD)., Design: Cross-sectional population cohort study of peri-menopausal women., Methods: Of a sample of 6846 peri-menopausal Dutch women who participated in an osteoporosis-screening programme, a cohort of 2584 was randomly selected for the assessment of thyroid function (TSH, fT₄ and thyroid peroxidase antibodies (TPO-Abs)). TPO-Ab-positive women, with a previous history of thyroid dysfunction, overt thyroid disease, subclinical hypothyroidism, osteoporosis or bilateral oophorectomy and those receiving thyroid hormone or hormone replacement therapy were excluded. Of 1477 eligible women, 1426 had TSH and fT₄ within the reference range and 51 had low or undetectable serum TSH. BMD was measured at the lumbar spine and low BMD was defined as <0.937 g/cm(2)., Results: The mean BMD in the 51 women with low or undetectable serum TSH was 0.984 g/cm(2) compared with 1.001 g/cm(2) in the remaining 1426 (t=0.94, P=0.35); 33% of women with low or undetectable serum TSH had low BMD compared with 34% in 1426 euthyroid women. High fT₄ but not low TSH in euthyroid women was related to low BMD by multiple logistic regression corrected for age, BMI and smoking (OR, 1.30; 95% CI, 1.02-1.69)., Conclusions: Higher fT₄ levels within the normal reference range but not low or undetectable serum TSH were independently related to decreased BMD at lumbar spine in peri-menopausal women.

Background: Recent guidelines on cardiovascular disease prevention advocate the importance of psychological risk factors, as they contribute to the risk of developing cardiovascular disease. However, most previous research on psychological distress and cardiovascular factors has focused on selected populations with cardiovascular disease., Aim: The primary aim was to determine the prevalence of depression, anxiety, and Type D personality in elderly primary care patients with hypertension. Secondary aim was to examine the relation between elevated systolic blood pressure and depression, anxiety, and Type D personality., Design and Setting: A cross-sectional study in primary care practices located in the south of the Netherlands., Method: Primary care hypertension patients (N = 605), between 60 and 85 years (45 % men, mean age = 70 ± 6.6), were recruited for this study. All patients underwent a structured interview including validated self-report questionnaires to assess depression (PHQ-9), anxiety (GAD-7), and Type D personality (DS14) as well as blood pressure assessment., Results and Conclusion: Depression was prevalent in 5 %, anxiety in 5 %, and Type D personality in 8 %. None of the distress measures were associated with elevated systolic blood pressure of >160 mmHg (all p-values >0.05). This study showed no relation between psychological distress and elevated systolic blood pressure in elderly primary care patients with hypertension.

The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration., (© 2012 John Wiley & Sons Ltd.)

In 2011, the American Thyroid association published guidelines concerning the attitude toward maternal thyroid (dys)function during pregnancy and postpartum. The American Association of Clinical Endocrinologists also -recommend a case-finding approach although several studies has shown that up to 50% of women with thyroid dysfunction will be missed. Recently, it was shown that 0.6% of all pregnant women suffer from unknown overt hypothyroidism as a consequence of not screening: annually 1000 women in the Netherlands, 6000 in UK and over 24.000 in the US. Cost-effective studies have shown that screening of all pregnant women is beneficial. This commentary criticizes the guidelines that (incorrectly) use RCT principles rather than following the more modern concepts of preventive medicine. Assessing a risk profile for an endocrine syndrome does not necessarily mean intervention per se. Informing women that they are at great risk for developing future thyroid dysfunction might help to reduce the tremendous patient and doctor delay of diagnosing hypothyroidism in pregnancy.

Objective: COPD-guidelines recommend regular evaluation of both the degree of airway obstruction and health-status to provide adequate treatment. Numerous health-status questionnaires have been developed of which the 'Clinical-COPD-Questionnaire' and the 'COPD-Assessment-Test' are best known; although highly recommended, both have several limitations regarding structure, content, and/or methodological qualities. In the present study a new COPD-specific instrument was developed to measure impairment: the 'Patient-centred-COPD-Questionnaire' (PCQ)., Methods: Six focus groups with COPD patients and (lung) health care providers from primary, secondary and tertiary (rehabilitation) care were formed to discuss aspects of COPD most relevant to patients' daily lives. Eighty candidate items were derived for explorative factor analyses (EFA) to test their psychometric properties (study I, n=541). These resulted in an 18-item scale that was further explored by confirmatory factor analyses (CFA) and construct and concurrent validity assessment (study II, n=412)., Results: EFA in study I suggested a reliable three component solution ('shortness of breath', 'acceptance of COPD' and 'confidence in care'). In study II this model was confirmed with CFA, and significant and clinically relevant correlations were found between the PCQ subscales, and other COPD specific and general health questionnaires. Furthermore, multivariate analyses of covariance revealed that more severely ill patients reported more impairment., Conclusions: The PCQ is a questionnaire with three dimensions to assess the impact of COPD on daily life that is easy to complete. For the first time, a dimension referring to 'confidence in care' is included in a tool that assesses COPD-related impairment., (© 2013.)

Objective: To examine whether depressive symptoms are associated with time to insulin initiation in insulin-naïve people with type 2 diabetes in primary care., Methods: 1,389 participants completed the Edinburgh Depression Scale (EDS) in 2005 and were followed until: 1) insulin therapy was started, 2) death, 3) an oral antihyperglycemic drug (OAD) prescription gap >1 year, 4) last OAD prescription in 2010 or 5) the end of the study (December 31, 2010). Cox regression analyses were used to determine whether there was a difference in time to insulin initiation between people with a low versus a high depression score at baseline, adjusting for potential demographic and clinical confounders, including HbA1c levels., Results: The prevalence of depression (EDS ≥ 12) was 12% (n=168). After a mean follow-up of 1,597 ± 537 days, 253 (18%) participants had started insulin therapy. The rate of insulin initiation did not differ between depressed and non-depressed participants. People with depression were not more likely to start insulin therapy earlier or later than their non-depressed counterparts (HR=0.98, 95% CI 0.66-1.45), also after adjustment for sex and age (HR=0.95, 0.64-1.42). The association remained non-significant when individual candidate confounders were added to the age- and sex-adjusted base model., Conclusions: In the present study, depression was not associated with time to insulin initiation. The hypothesis that depression is associated with delayed initiation of insulin therapy merits more thorough testing, preferably in studies where more information is available about patient-, provider- and health care system factors that may influence the decision to initiate insulin.

Objective: To compare the obstetric outcomes of pregnant women after successful external cephalic version (ECV) (cases) with a large group of pregnant women with a spontaneously occurring cephalic fetal position at delivery (controls)., Methods: We conducted a retrospective matched cohort study in a teaching hospital in the Netherlands. Delivery outcomes of women with a successful ECV were compared with those of women with spontaneously occurring cephalic presentations, controlling for maternal age, parity, gestational age at delivery, and onset of labour (spontaneous or induced). Exclusion criteria were a history of Caesarean section, delivery at < 35 weeks, and elective Caesarean section. The primary outcome was the prevalence of Caesarean section and instrumental delivery in both groups; secondary outcomes were the characteristics of cases requiring intervention such as Caesarean section or instrumental delivery., Results: Women who had a successful ECV had a significantly higher Caesarean section rate than the women in the control group (33/220 [15%] vs. 62/1030 [6.0 %]; P < 0.001). There was no difference in the incidence of instrumental delivery (20/220 [9.1%] vs. 103/1030 [10%]). Comparison of characteristics of women in the cases group showed that nulliparity, induction of labour, and occiput posterior presentation were associated with Caesarean section and instrumental deliveries., Conclusion: Compared with delivery of spontaneous cephalic presenta-tions, delivery of cephalic presenting babies following successful ECV is associated with an increased rate of Caesarean section, especially in nulliparous women and women whose labour is induced.

Context: Obesity and too much weight gain during gestation have a negative effect on obstetric and neonatal outcomes., Objective: To determine the relationship between thyroid hormone parameters, body mass index (BMI) and weight gain during gestation., Design: Prospective follow-up study of thyroid parameters and gestational weight gain., Setting: Healthy pregnant women, included at first antenatal consultation., Patients: Thyroid function (TSH, FT4 and TPO-Ab) was assessed at 12, 24 and 36 weeks' gestation in 1035 Dutch Caucasian women who delivered at ≥37 weeks. BMI (WHO criteria) was assessed at eight weeks, and weight gain throughout gestation was also assessed using the US Institute of Medicine (IOM) criteria., Primary Outcome Measure: a possible relationship between maternal thyroid parameters and BMI at the first trimester., Secondary Outcome Measure: the relationship between thyroid parameters and weight gain throughout gestation., Results: At 12 weeks' gestation, BMI correlated with FT4 (r = -0·14, P < 0·001), but not with TSH (r = 0·04, P = 0·89). 415 (40%) of the women met the IOM criteria for appropriate weight gain, 326 (32%) showed less weight gain and 294 (28%) gained too much weight. At all trimesters, the latter group of women showed higher median TSH and lower median FT4 compared with those with normal weight gain. FT4 at 24 weeks' gestation (OR: 0·84, 95% CI: 0·77-0·91), younger age (OR: 0·97, 95% CI: 0·95-0·99) and primiparity (OR: 0·51, 95% CI: 0·38-0·68) were independently related to too much weight gain., Conclusions: Maternal thyroid parameters are related to both prepregnancy BMI and weight gain throughout gestation., (© 2013 John Wiley & Sons Ltd.)

Aims/hypothesis: Psychological problems are relatively common in people with type 2 diabetes. It is unclear whether exercise training exerts an effect on quality of life, symptoms of depression, symptoms of anxiety and emotional well-being in people with type 2 diabetes. The aim of this study was to conduct a systematic review to assess the effects of exercise training on these outcomes in people with type 2 diabetes., Methods: MEDLINE, PsycINFO, Embase and ClinicalTrials.gov databases were searched. The review included randomised controlled trials (RCTs) of at least 4 weeks' duration in people with type 2 diabetes that evaluated the effect of exercise training on quality of life, symptoms of depression, symptoms of anxiety and/or emotional well-being compared with usual care., Results: Of 1,261 retrieved articles, 20 RCTs were included with a total of 1,719 participants. Quality of life was assessed in 16 studies. Between-group comparisons showed no significant results for aerobic training with the exception of one study, and mixed results for resistance and combined training. Symptoms of depression were assessed in four studies. In only one study did the intervention decrease symptoms of depression. Emotional well-being was evaluated in four studies, which also showed conflicting results. Symptoms of anxiety were evaluated in one study, which showed a significant improvement., Conclusions/interpretation: The effects of exercise training on psychological outcomes in people with type 2 diabetes are conflicting. Therefore, there is a need for further high-quality RCTs in order to gain greater insight into the role of exercise training in people with type 2 diabetes.

Background: Accumulating evidence suggests that dysregulation of the immune system represents an important vulnerability factor for mood disorders. Postpartum psychosis (PP) is a severe mood disorder occurring within 4 weeks after delivery, a period of heightened immune responsiveness and an altered endocrine set point. Therefore, the aim of this study was to examine immune activation in patients with first-onset PP at the level of monocytes, T cells, and serum cytokines/chemokines., Methods: We included 63 women admitted with first-onset PP. Control groups included healthy postpartum (n = 56) and nonpostpartum (n = 136) women. A quantitative-polymerase chain reaction monocyte gene expression analysis was performed with 43 genes previously identified as abnormally regulated in nonpostpartum mood disorder patients including the isoforms of the glucocorticoid receptor. Peripheral blood mononuclear cells percentages were measured by fluorescence-activated cell sorter analysis, whereas serum cytokines/chemokines were determined with a cytometric bead array., Results: In healthy women, postpartum T cell levels were significantly elevated compared with nonpostpartum. Patients with PP failed to show the normal postpartum T cell elevation. In contrast, these patients showed a significant elevation of monocyte levels and a significant upregulation of several immune-related monocyte genes compared with control subjects postpartum and nonpostpartum. Furthermore, the glucocorticoid receptor α/β gene expression ratio was decreased in monocytes of PP patients, strongly correlating with their immune activation., Conclusions: This study demonstrates a robust dysregulation of the immuno-neuro-endocrine set point in PP, with a notable over-activation of the monocyte/macrophage arm of the immune system., (Copyright © 2013 Society of Biological Psychiatry.

Objective: Emotional distress is common in outpatients with diabetes, affecting ∼20-40% of the patients. The aim of this study was to determine the effectiveness of group therapy with Mindfulness-Based Cognitive Therapy (MBCT), relative to usual care, for patients with diabetes with regard to reducing emotional distress and improving health-related quality of life and glycemic control., Research Design and Methods: In the present randomized controlled trial, 139 outpatients with diabetes (type 1 or type 2) and low levels of emotional well-being were randomized to MBCT (n = 70) or a waiting list group (n = 69). Primary outcomes were perceived stress (Perceived Stress Scale), anxiety and depressive symptoms (Hospital Anxiety and Depression Scale), mood (Profiles of Mood States), and diabetes-specific distress (Problem Areas In Diabetes). Secondary outcomes were health-related quality of life (12-Item Short-Form Health Survey), and glycemic control (HbA(1c)). Assessments were conducted at baseline and at 4 and 8 weeks of follow-up., Results: Compared with control, MBCT was more effective in reducing stress (P < 0.001, Cohen d = 0.70), depressive symptoms (P = 0.006, d = 0.59), and anxiety (P = 0.019, d = 0.44). In addition, MBCT was more effective in improving quality of life (mental: P = 0.003, d = 0.55; physical: P = 0.032, d = 0.40). We found no significant effect on HbA(1c) or diabetes-specific distress, although patients with elevated diabetes distress in the MBCT group tended to show a decrease in diabetes distress (P = 0.07, d = 0.70) compared with the control group., Conclusions: Compared with usual care, MBCT resulted in a reduction of emotional distress and an increase in health-related quality of life in diabetic patients who had lower levels of emotional well-being.

Objective: To assess the association between baseline levels of highly sensitive cardiac troponin T (hs-cTnT) and long-term mortality in perimenopausal women of the general community using a gender specific 99th percentile reference limit., Design: Nested case control., Setting: The present study was conducted within the Eindhoven Perimenopausal Osteoporosis Study which is a large prospective cohort of 8503 community-derived women of the city of Eindhoven, The Netherlands., Participants: Cases were defined as Eindhoven Perimenopausal Osteoporosis Study participants who provided an adequate baseline blood sample and subsequently experienced death during follow-up between 1994 and 2003. In total, 123 cases were identified. For each case two matched controls were selected using age, body mass index and hypertension as matching factors. The gender specific 99th percentile reference limit determined in the 246 controls was 8.0 ng/l., Main Outcome Measure: All cause mortality., Results: Hs-cTnT was significantly higher in the cases: 3.0 ng/l versus 2.3 ng/l (p=0.04). After adjustment for matching and clinical risk factors, each 1 SD increase of the level of hs-cTnT was significantly associated with mortality (OR 1.3, 95% CI 1.1 to 1.7, p=0.018). With amino-terminal pro-B-type natriuretic peptide (NT-proBNP) in the multivariable model as a continuous variable the association of hs-cTnT with mortality was lost. With both hs-cTnT and NT-proBNP as dichotomous variables, the gender specific 99th percentile reference limit (8.0 ng/l) was associated with mortality, independent of NT-proBNP (OR 3.7, 95% CI 1.0 to 13.2, p=0.048)., Conclusions: In this study of community-derived perimenopausal women, hs-cTnT was associated with long-term mortality, independent of clinical risk factors. With the use of easily applicable cut-off levels, the gender specific reference limit of hs-cTnT had a prognostic impact that was independent of NT-proBNP.

Background: Anxiety disorders are prevalent and associated with poor prognosis in patients with coronary artery disease (CAD). However, studies examining screening of anxiety disorders in CAD patients are lacking. In the present study we evaluated the prevalence of anxiety disorders in patients with CAD and diagnostic utility of self-rating scales for screening of anxiety disorders., Methods: Five-hundred and twenty-three CAD patients not receiving psychotropic treatments at initiation of rehabilitation program completed self-rating scales (Hospital Anxiety and Depression Scale or HADS; Spielberger State-Anxiety Inventory or SSAI; and Spielberger Trait-Anxiety Inventory or STAI) and were interviewed for generalized anxiety disorder (GAD), social phobia, panic disorder and agoraphobia (Mini-International Neuropsychiatric Interview or MINI)., Results: Thirty-eight (7%) patients were diagnosed with anxiety disorder(s), including GAD (5%), social phobia (2%), agoraphobia (1%) and panic disorder (1%). Areas under the ROC curve of the HADS Anxiety subscale (HADS-A), STAI and SSAI for screening of any anxiety disorder were .81, .80 and .72, respectively. Optimal cut-off values for screening of any anxiety disorders were ≥ 8 for the HADS-A (sensitivity = 82%; specificity = 76%; and positive predictive value (PPV) = 21%); ≥ 45 for the STAI (sensitivity = 89%; specificity = 56%; and PPV = 14%); and ≥ 40 for the SSAI (sensitivity = 84%; specificity = 55%; PPV = 13%). In a subgroup of patients (n = 340) scoring below the optimal major depressive disorder screening cut-off value of HADS-Depression subscale (score <5), the HADS-A, STAI and SSAI had moderate-high sensitivity (range from 69% to 89%) and low PPVs (≤ 22%) for GAD and any anxiety disorders., Conclusions: Anxiety disorders are prevalent in CAD patients but can be reliably identified using self-rating scales. Anxiety self-rating scales had comparable sensitivities but the HADS-A had greater specificity and PPV when compared to the STAI and SSAI for screening of anxiety disorders. However, false positive rates were high, suggesting that patients with positive screening results should undergo psychiatric interview prior to initiating treatment for anxiety disorders and that routine use of anxiety self-rating scales for screening purposes can increase healthcare costs. Anxiety screening has incremental value to depression screening for identifying anxiety disorders.

The aim of this study was to evaluate, in patients with coronary artery disease (CAD), factor structure and psychometric properties of the Montgomery Åsberg Depression Rating Scale (MADRS) to identify patients with current major depressive episode (MDE). The construct validity of the MADRS against self-rating scales was also evaluated. Consecutive 522 CAD patients at admission to the cardiac rehabilitation program were interviewed for the severity of depressive symptoms using the MADRS and for current MDE using the structured MINI International Neuropsychiatric Interview. Also, all patients completed the Hospital Anxiety and Depression Scale and the Beck Depression Inventory-II. The MADRS had one-factor structure and high internal consistency (Cronbach's coefficient α=0.82). Confirmative factor analysis indicated an adequate fit: comparative fit index=0.95, normed fit index=0.91, and root mean square error of approximation=0.07. At a cut-off value of 10 or higher, the MADRS had good psychometric properties for the identification of current MDE (positive predictive value=42%, with sensitivity=88% and specificity=85%). There was also a moderate to strong correlation of MADRS scores with scores on self-rating depression scales. In sum, in CAD patients undergoing rehabilitation, the MADRS is a unidimensional instrument with high internal consistency and can be used for the identification of depressed CAD patients. The association between MADRS and self-rating depression scores is moderate to strong., (© 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins.)

Background: Sufficient exercise is important for people with Type 2 Diabetes Mellitus (T2DM), as it can prevent future health problems. Despite, it is estimated that only 30-40% of people with T2DM are sufficiently active. One of the psychosocial constructs that is believed to influence physical activity behaviour, is exercise self-efficacy. The goal of this study is to evaluate a patient-tailored exercise intervention for people with T2DM that takes exercise self-efficacy into account., Methods/design: This study is conducted as a non-randomized controlled clinical trial. Patients are eligible when they are diagnosed with T2DM, exercise less than advised in the ADA guideline of 150 min/week of moderate-intensity aerobic physical activity, have an BMI >25 and are between 18 and 80 years old. Recruitment takes place at a Primary care organization of general practitioners and practice nurses in the south of the Netherlands.Participants are allocated to three groups: An advice intervention -for participants with a high exercise self-efficacy score- in which participants receive a patient-tailored exercise intervention, an intensive intervention -for participants with a low exercise self-efficacy score- in which participants receive a patient-tailored exercise intervention accomplished by a group based intervention, and a control group in which participants receive regular Dutch diabetes care. The primary outcome measure of this study is physical activity. Secondary outcome measures are health status, (symptoms of) depression, exercise self-efficacy, Body Mass Index (BMI), blood pressure and glycemic control., Discussion: We aimed to design an intervention that can be implemented in Primary care, but also to design an easy accessible program. This study is innovative as it is -to our best knowledge- the first study that takes level of exercise self-efficacy of people with T2DM into account by means of giving extra support to those with the lowest exercise self-efficacy. If the program succeeds in increasing the amount of physical activity it can be implemented in regular primary care., Trial Registration: Dutch Trial Register NTR2734.

Recent studies examining the relationship between depression and glycosylated hemoglobin (HbA(1c)) concentrations in patients with type 2 diabetes have yielded mixed findings. One explanation may lie in the heterogeneity of depression. Therefore, we examined whether distinct features of depression were differentially associated with suboptimal glycemic control. Cross-sectional baseline data from a dynamic cohort study of primary care patients with type 2 diabetes from the Eindhoven region, The Netherlands, were analyzed. A total of 5772 individuals completed baseline measurements of demographic, clinical, lifestyle and psychological factors between 2005 and 2009. The Edinburgh Depression Scale was used to assess symptoms of depressed mood, anhedonia and anxiety. Suboptimal glycemic control was defined as HbA(1c) values ≥7%, with 29.8% of the sample (n=1718) scoring above this cut-off. In univariate logistic regression analyses, anhedonia was significantly associated with suboptimal glycemic control (OR 1.29, 95% CI 1.09-1.52), while both depressed mood (OR 1.04, 0.88-1.22) and anxiety (OR 0.99, 0.83-1.19) were not. The association between anhedonia and glycemic control remained after adjustment for the other depression measures (OR 1.33, 1.11-1.59). Alcohol consumption and physical activity met criteria for mediation, but did not attenuate the association between anhedonia and glycemic control by more than 5%. Although diabetes duration was identified as a confounder and controlled for, the association was still significant (OR 1.20, 1.01-1.43). Studying different symptoms of depression, in particular anhedonia, may add to a better understanding of the relationship between depression and glycemic control., (Copyright © 2012 Elsevier Ltd.

To newly identify loci for age at natural menopause, we carried out a meta-analysis of 22 genome-wide association studies (GWAS) in 38,968 women of European descent, with replication in up to 14,435 women. In addition to four known loci, we identified 13 loci newly associated with age at natural menopause (at P < 5 × 10(-8)). Candidate genes located at these newly associated loci include genes implicated in DNA repair (EXO1, HELQ, UIMC1, FAM175A, FANCI, TLK1, POLG and PRIM1) and immune function (IL11, NLRP11 and PRRC2A (also known as BAT2)). Gene-set enrichment pathway analyses using the full GWAS data set identified exoDNase, NF-κB signaling and mitochondrial dysfunction as biological processes related to timing of menopause.

Background: Chronic obstructive pulmonary disease (COPD) and asthma are common chronic diseases that are frequently accompanied by depression and/or anxiety. However, symptoms of depression and anxiety are often not recognized and therefore not treated. Currently, only a few studies have tested new clinical approaches that could improve the treatment of co-morbid depression and anxiety in these groups of patients., Methods/design: The present randomized controlled study will be conducted within the framework of PoZoB (Praktijk Ondersteuning Zuid-Oost Brabant), a large primary care organization in the Netherlands. Patients with asthma/COPD and co-morbid anxiety/depression will be included in order to test the effectiveness of a disease management approach to treat these co-morbid disorders. Important elements of this approach are: 1) systematic screening to improve detection of anxiety and depression 2) treatment in case of positive screening 3) monitoring of anxiety and depression 4) intensified treatment in case of non-remission (stepped care)., Discussion: The present study is a large primary care study on the treatment of co-morbid depression and anxiety in patients with asthma and COPD. Strengths of this study are its randomized design, the focus on implementation in primary care and the fact that it applies the latest findings on the treatment of depression and anxiety. First results are expected in 2012/2013.

Background: Depression and anxiety are common co-morbid health problems in patients with type 2 diabetes. Both depression and anxiety are associated with poor glycaemic control and increased risk of poor vascular outcomes and higher mortality rates. Results of previous studies have shown that in clinical practice, treatment of depression and anxiety is far from optimal as these symptoms are frequently overlooked and undertreated., Methods/design: This randomised controlled trial will examine the effectiveness of a disease management programme treating symptoms of depression and anxiety in primary care patients with Type 2 diabetes. Patients will be randomized on patient level in 1:1 ratio. Random block sizes of 2 and 4 are used. The disease management programme consists of screening, stepped treatment and monitoring of symptoms (n = 80). This will be compared to care as usual (n = 80)., Discussion: The disease management model for co-morbid depression and anxiety in primary care patients with diabetes is expected to result in reduced symptoms of depression and anxiety, improved quality of life, reduced diabetes specific distress and improved glyceamic control, compared to care as usual., Trial Registration: Dutch Trial Register NTR2626.

Background: Falls are one of the main causes of fractures in elderly people and after a recent fracture, the risk of another fall is increased, resulting in subsequent fracture. Therefore, risk factors for future falls should be determined. We prospectively investigated the relationship between depression and the incidence of falls in post-menopausal women after a low-energy fracture., Methods: At baseline, 181 women aged 60 years and older who presented with a recent low-energy fracture were evaluated at the fracture and osteoporosis outpatient clinics of two hospitals. As well as clinical evaluation and bone mineral density tests, the presence of depression (measured using the Edinburgh Depression Scale, EDS, depression cut-off > 11) and risk factors for falling were assessed. During two years of follow-up, the incidence of falls was registered annually by means of detailed questionnaires and interviews., Results: Seventy-nine (44%) of the women sustained at least one fall during follow-up. Of these, 28% (n = 22) suffered from depression at baseline compared to 10% (n = 10) of the 102 women who did not sustain a fall during follow-up (Χ(2) = 8.76, df = 1, p = .003). Multiple logistic regression showed that the presence of depression and co-morbidity at baseline were independently related to falls (OR = 4.13, 95% CI = 1.58-10.80; OR = 2.25, 95% CI = 1.11-4.56, respectively) during follow-up., Conclusions: The presence of depression in women aged 60 years and older with recent low-energy fractures is an important risk factor for future falls. We propose that clinicians treating patients with recent low-energy fractures should anticipate not only on skeletal-related risk factors for fractures, but also on fall-related risk factors including depression., (© 2011 van den Berg et al; licensee BioMed Central Ltd.)

Background: Pregnant women with high levels of stress, depression and/or anxiety are at increased risk for adverse perinatal outcomes and impaired neurologic and emotional development of the offspring. Pregnancy specific instruments to measure psychological functioning during gestation are scarce and do not define items based on in-depth interviews of pregnant and recently delivered women. The current study developed a pregnancy specific scale that measures psychological functioning using in-depth interviews., Methods: Three focus groups were formed to discuss issues most relevant to pregnancy distress; 22 candidate items were derived for pilot testing (study I, n = 419) its psychometric properties by means of explorative factor analyses (EFA). This resulted in a 17-item TPDS which was further explored by confirmatory factor analyses (CFA) and concurrent and construct validity assessment (study II, n = 454)., Results: EFA in study I suggested a two component solution (negative affect (NA) and partner involvement (PI)). CFA in study II resulted in a higher order model of the NA subscale into three more subscales: NA regarding confinement, delivery and general health. TPDS, EPDS and GAD-7 were all significantly correlated., Conclusions: The TPDS constitutes a valid and user friendly instrument to assess pregnancy distress. In addition to its proven ability to pick up pregnancy specific negative affect it also includes an important sub-scale measuring perceived partner involvement.

Objective: To study the relationship between maternal thyroid function at each pregnancy trimester and neonatal screening results., Background: Overt maternal thyroid dysfunction during gestation is associated with poor neonatal thyroid function. However, research on the relationship between suboptimal maternal thyroid function (assessed at three trimesters) and neonatal thyroid screening outcome is scarce., Design/patients: Prospective follow-up study during three trimesters of gestation in 886 Dutch Caucasian healthy pregnant women followed from 12-week gestation until term delivery (>37 weeks) and their neonates., Measurements: The relation between neonatal data from the Congenital Hypothyroidism (CH) screening and maternal thyroid determinants [TSH, FT4 and thyroid peroxidase (TPO)-Ab] assessed at 12-, 24- and 36-week gestation., Results: Boys have lower screening TT4 levels and their mothers have higher TSH levels at 24- and 36-week gestation. Higher maternal TSH levels (>97·5th percentile, as defined in 810 women without TPO-Ab at 12 weeks) at one or more times during pregnancy (O.R: 2·26, 95% CI: 1·20-4·29) and lower gestational age (O.R: 1·22, 95% CI: 1·05-1·41) are independently related to lower screening TT4 levels., Conclusions: Maternal thyroid function during gestation is related to neonatal TT4 at screening. The finding of both lower neonatal TT4 levels in boys and higher TSH levels in mothers carrying boys is worthy of further investigation, as both observations may be meaningfully related., (© 2011 Blackwell Publishing Ltd.)

Background: Depression is a common complication in type 2 diabetes (DM2), affecting 10-30% of patients. Since depression is underrecognized and undertreated, it is important that reliable and validated depression screening tools are available for use in patients with DM2. The Edinburgh Depression Scale (EDS) is a widely used method for screening depression. However, there is still debate about the dimensionality of the test. Furthermore, the EDS was originally developed to screen for depression in postpartum women. Empirical evidence that the EDS has comparable measurement properties in both males and females suffering from diabetes is lacking however., Methods: In a large sample (N = 1,656) of diabetes patients, we examined: (1) dimensionality; (2) gender-related item bias; and (3) the screening properties of the EDS using factor analysis and item response theory., Results: We found evidence that the ten EDS items constitute a scale that is essentially one dimensional and has adequate measurement properties. Three items showed differential item functioning (DIF), two of them showed substantial DIF. However, at the scale level, DIF had no practical impact. Anhedonia (the inability to be able to laugh or enjoy) and sleeping problems were the most informative indicators for being able to differentiate between the diagnostic groups of mild and severe depression., Conclusions: The EDS constitutes a sound scale for measuring an attribute of general depression. Persons can be reliably measured using the sum score. Screening rules for mild and severe depression are applicable to both males and females.

Background: Umbilical cords of fetuses in breech presentation differ in length and coiling from their cephalic counterparts and it might be hypothesised that these cord characteristics may in turn affect ECV outcome., Aim: To investigate the relation between umbilical cord characteristics and the outcome of external cephalic version (ECV)., Study Design: Prospective cohort study., Subjects: Women (>35 weeks gestation) with a singleton fetus in breech presentation, suitable for external cephalic version. Demographic, lifestyle and obstetrical parameters were assessed at intake. ECV success was based on cephalic presentation on ultrasound post-ECV. Umbilical cord length (UCL) and umbilical coiling index (UCI) were measured after birth., Outcome Measure: The relation between umbilical cord characteristics (cord length and coiling) and the success of external cephalic version., Results: ECV success rate was overall 79/146 (54%), for multiparas 37/46(80%) and for nulliparas 42/100 (42%). Multiple logistic regression showed that UCL (OR: 1.04, CI: 1.01-1.07), nulliparity (OR: 0.20, CI: 0.08-0.51), frank breech (OR: 0.37, 95% CI: 0.15-0.90), body mass index (OR: 0.85, CI: 0.76-0.95), placenta anterior (OR: 0.27, CI: 0.12-0.63) and birth weight (OR: 1.002, CI: 1.001-1.003) were all independently related to ECV success., Conclusions: Umbilical cord length is independently related to the outcome of ECV, whereas umbilical coiling index is not., (Copyright © 2011 Elsevier Ltd.

Background: Approximately 20-40% of outpatients with diabetes experience elevated levels of emotional distress, varying from disease-specific distress to general symptoms of anxiety and depression. The patient's emotional well-being is related to other unfavorable outcomes, like reduced quality of life, sub-optimal self-care, impaired glycemic control, higher risk of complications, and increased mortality rates. The purpose of this study is to test the effectiveness of a new diabetes-specific, mindfulness-based psychological intervention. First, with regard to reducing emotional distress; second, with respect to improving quality of life, dispositional mindfulness, and self-esteem of patients with diabetes; third, with regard to self-care and clinical outcomes; finally, a potential effect modification by clinical and personality characteristics will be explored., Methods/design: The Diabetes and Mindfulness study (DiaMind) is a randomized controlled trial. Patients with diabetes with low levels of emotional well-being will be recruited from outpatient diabetes clinics. Eligible patients will be randomized to an intervention group or a wait-list control group. The intervention group will receive the mindfulness program immediately, while the control group will receive the program eight months later. The primary outcome is emotional distress (anxiety, stress, depressive symptoms), for which data will be collected at baseline, four weeks, post intervention, and after six months follow-up. In addition, self-report data will be collected on quality of life, dispositional mindfulness, self-esteem, self-care, and personality, while complications and glycemic control will be assessed from medical files and blood pressure will be measured. Group differences will be analyzed with repeated measures analysis of covariance.The study is supported by grants from the Dutch Diabetes Research Foundation and Tilburg University and has been approved by a medical ethics committee., Discussion: It is hypothesized that emotional well-being, quality of life, dispositional mindfulness, self-esteem, self-care, and blood pressure will improve significantly more in the mindfulness group compared to the control group. Results of this study can contribute to a better care for patients with diabetes with lowered levels of emotional well-being. It is expected that the first results will become available in 2012., Trial Registration: Dutch Trial Register NTR2145.

Background: To investigate the relation between maternal thyroid function and the outcome of external cephalic version (ECV) in breech presentation., Methods: Prospective cohort study in 141 women (≥ 35 weeks gestation) with a singleton fetus in breech. Blood samples for assessing thyroid function were taken prior to ECV. Main outcome measure was the relation between maternal thyroid function and ECV outcome indicated by post ECV ultrasound., Results: ECV success rate was 77/141 (55%), 41/48 (85%) in multipara and 36/93 (39%) in primipara. Women with a failed ECV attempt had significantly higher TSH concentrations than women with a successful ECV (p < 0.001). Multiple logistic regression showed that TSH (OR: 0.52, 95% CI: 0.30-0.90), nulliparity (OR: 0.11, 95% CI: 0.03-0.36), frank breech (OR: 0.30, 95% CI: 0.10-0.93) and placenta anterior (OR: 0.31, 95% CI: 0.11-0.85) were independently related to ECV success., Conclusions: Higher TSH levels increase the risk of ECV failure., Trial Registration Number: ClinicalTrials.gov: NCT00516555.

Objective: To study the relationship between maternal thyrotrophin (TSH) and breech presentation at term., Design: Combined data sets of two prospective studies to obtain adequate epidemiological power., Patients: One thousand and fifty-eight healthy pregnant women (58 breech, 1000 cephalic) and 131 women who presented in breech at an obstetrical outpatient clinic., Measurements: Maternal thyroid parameters [TSH, free thyroid hormone (FT4), thyroid peroxidase antibody (TPO-Ab)] and foetal presentation were assessed in both groups between 35 and 38 weeks gestation. Power calculations suggested that at least 148 breech cases were required., Results: The characteristics of the women in breech in both samples were similar. Women in breech (n = 58 + 131) had significantly higher TSH (but not FT4) than those (n = 1000) with cephalic presentation (Mann-Whitney U-test, P = 0·003). Different cut-offs were used to define high TSH in the 916 TPO-Ab-negative women with cephalic presentation: the 90th, 95th and 97·5th percentiles were 2·4 mIU/l (n = 149), 2·7 mIU/l (n = 77) and 3·2 mIU/l (n = 37). The prevalence rates of breech presentation in these women were all higher compared to the prevalence of breech in women below these cut-offs (df = 1, P < 0·01). The relative risk of the 149 women with a TSH >90th percentile (>2·4 mIU/l) to present in breech was 1·82 (95% CI: 1·30-2·56)., Conclusions: Women with high TSH at end term are at risk for breech presentation. Substantial evidence for a relation between breech presentation and neurodevelopmental delay exists. As high TSH during gestation has also been linked to poor neurodevelopment, the relation between breech presentation and poor neurodevelopment might be thyroid-related., (© 2010 Blackwell Publishing Ltd.)

Background: Depression is a common psychiatric complication of diabetes, but little is known about the natural course and the consequences of depressive symptoms in primary care patients with type 2 diabetes. While depression has been related to poor glycemic control and increased risk for macrovascular disease, its association with microvascular complications remains understudied. The predictive role of other psychological risk factors such as Type D (distressed) personality and the mechanisms that possibly link depression and Type D personality with poor vascular outcomes are also still unclear., Methods/design: This prospective cohort study will examine: (1) the course of depressive symptoms in primary care patients with type 2 diabetes; (2) whether depressive symptoms and Type D personality are associated with the development of microvascular and/or macrovascular complications and with the risk of all-cause or vascular mortality; and (3) the behavioral and physiological mechanisms that may mediate these associations. The DiaDDZoB Study is embedded within the larger DIAZOB Primary Care Diabetes study, which covers a comprehensive cohort of type 2 diabetes patients treated by over 200 primary care physicians in South-East Brabant, The Netherlands. These patients will be followed during their lifetime and are assessed annually for demographic, clinical, lifestyle and psychosocial factors. Measurements include an interviewer-administered and self-report questionnaire, regular care laboratory tests and physical examinations, and pharmacy medication records. The DiaDDZoB Study uses data that have been collected during the original baseline assessment in 2005 (M0; N = 2,460) and the 2007 (M1; N = 2,225) and 2008 (M2; N = 2,032) follow-up assessments., Discussion: The DiaDDZoB Study is expected to contribute to the current understanding of the course of depression in primary care patients with type 2 diabetes and will also test whether depressed patients or those with Type D personality are at increased risk for (further) development of micro- and cardiovascular disease. More knowledge about the mechanisms behind this association is needed to guide new intervention studies.

Objective: To study the relationship between suboptimal maternal thyroid function during gestation and breech presentation at term., Design: Prospective follow-up study during three trimesters of gestation., Patients: A total of 1058 Dutch Caucasian healthy pregnant women were prospectively followed from 12 weeks gestation until term (>or=37 weeks) delivery., Measurements: Maternal thyroid parameters [TSH, free T4 (FT4) and auto-antibodies to thyroid peroxidase] were assessed at 12, 24 and 36 weeks gestation as well as foetal presentation at term., Results: At term, 58 women (5.5%) presented in breech. Compared with women with foetuses in the cephalic position, those women who presented in breech at term had significantly higher TSH concentrations, but only at 36 weeks gestation (P = 0.007). No between group differences were obtained for FT4 level at any assessment. The prevalence of breech presentation in the subgroup of women with TSH >or= 2.5 mIU/l (90th percentile) at 36 weeks gestation was 11%, compared with 4.8% in the women with TSH < 2.50 mIU/l (P = 0.006). Women with TSH below the 5th percentile had no breech presentations. Breech position was significantly and independently related to high maternal TSH concentration (>or=2.5 mIU/l) at 36 weeks gestation (O.R.: 2.23, 95% CI: 1.14-4.39), but not at 12 and 24 weeks gestation., Conclusions: Women with TSH levels above 2.5 mIU/l during end gestation are at risk for breech presentation, and as such for obstetric complications.

Aim: To investigate the effect of implementation of a number of process policy guidelines (protocol), on the success rate of external cephalic version (ECV) for breech presentation., Design: Prospective study., Methods: During a 3-year period (2004-2006) a standardized protocol for an ECV consultation was developed, evaluated and adapted. After implementing this modified protocol as 'process policy guidelines', the effect on the rate of successful ECV was prospectively evaluated during the period 1 January 2007-31 July 2008. Success was defined as cephalic presentation (ultrasound) immediately after ECV. A secondary outcome measure was the elective caesarean section rate for breech presentation., Results: The rate of successful ECV increased significantly from 47% (110/236 pregnant women) in the period January 2004-December 2006 to 61% (85/139, p = 0.006) in the period January 2007-July 2008. Patient characteristics were similar in both groups, with the exception of 2 subgroups of term of version. The increase was preferentially found in nulliparous and multiparous women with frank breech. Nulliparity, frank breech, anterior placenta and low birth weight were associated with a lower success rate of ECV. The term of pregnancy at which ECV was performed did not seem to affect the success rate. Implementing the process policy guidelines increased the number of cephalic presentations at delivery and decreased the rate of elective caesarean sections for breech presentation from 39% to 27% (p = 0.03). The number needed to treat to prevent 1 elective caesarean section by ECV according to the process policy guidelines was 8., Conclusion: After implementation of the process policy guidelines, the success rate of ECV increased considerably. The rate of elective caesarean section for breech presentation declined. These findings are in favour of establishing specialized ECV centres in the Netherlands.

This study aimed to evaluate how precise the Edinburgh Depression Scale (EDS) is in screening for major depressive disorder (MDD) during different periods of pregnancy. A random sample of 230 pregnant women was interviewed in the first, second, and third trimesters of pregnancy using the EDS and not-patient version of the Structured Clinical Interview for DSM-III-R (SCID-NP). We evaluated test-retest reliability of the EDS; area under the ROC curve (AUC), sensitivity, specificity, and positive predictive value (PPV) of the EDS against the SCID-NP diagnoses in the first, second, and third trimesters of pregnancy. Test-retest reliability of the EDS was 0.81 (p < 0.001). An optimal cutoff score of the EDS for screening current SCID-NP diagnosis of MDD was 12 and higher in the first trimester of pregnancy (AUC 0.94, sensitivity 92%, specificity 95%, and PPV 52%) and 11 and higher in the second and third trimesters of pregnancy (AUC 0.96 and 0.90, respectively; sensitivity 100% and 88%, respectively; specificity 92% and 92%, respectively; PPV 25% and 29%, respectively). The EPDS is a reliable instrument for repeated evaluations of depressive symptoms during pregnancy. It has a good sensitivity and specificity for detecting antenatal MDD with optimal cutoff of 11/12 or higher.

Objective: To evaluate whether there is an association between maternal thyroid hormone and foetal cephalic head position at term gestation., Context: Rotation and flexion of the head enables the foetus to negotiate the birth canal. Low-normal range thyroid hormone concentrations in euthyroid pregnant women constitute a risk of infant motor abnormality. We hypothesized that low normal maternal thyroid hormone levels are associated with increased risk of abnormal foetal position at delivery., Design: In 960 healthy Dutch women with term gestation and cephalic foetal presentation, thyroid parameters [foetal T4 (FT4), TSH and thyroid peroxidase antibody] were assessed at 36 weeks of gestation, and related to foetal head position (anterior cephalic vs. abnormal cephalic) and delivery mode (spontaneous vs. assisted delivery)., Results: Women presenting in anterior position (n = 891) had significantly higher FT4 levels at 36 weeks of gestation than those with abnormal cephalic presentation (n = 69). There were no between-group differences for TSH. Regression analyses indicated that the risk of abnormal head position decreased as a function of increasing FT4 [single odds ratio (OR) = 0.87, 95% confidence intervals (CI) 0.77-0.98; multivariate OR = 0.88, 95% CI 0.72-0.99)]. A similar inverse relationship between maternal FT4 and risk of assisted delivery was obtained (OR = 0.86, 95% CI 0.79-0.95; OR = 0.91, 95% CI 0.84-0.98)., Conclusion: The lower the maternal FT4 concentration at 36 weeks of gestation, the higher the risk of abnormal cephalic foetal presentation and assisted delivery.

Associations between prenatal maternal emotional complaints and child behavioral and cognitive problems have been reported, with different relations for boys and girls. Fetal programming hypotheses underline these associations and state that the early development of the HPA-axis of the children may have been affected. In the present study, differences in cortisol responses of prenatally exposed and nonexposed children are examined for both sexes separately. Cortisol response patterns of a group preschool aged children that were prenatally exposed to high levels of maternal emotional complaints (N = 51) were compared to a nonexposed group (N = 52). Child saliva was collected at the start of a home visit (T1), 22 min after a mother-child interaction episode (T2), and 22 min after a potentially frustrating task (T3). Repeated measures analyses showed that prenatally exposed girls showed higher cortisol levels across the three episodes compared to nonexposed girls. No differences were found in boys. Maternal prenatal emotional complaints might be related to child HPA-axis functioning differently for boys and girls.

Aims/hypothesis: The aim of the study was to determine the prevalence of depression in insulin-naive diabetes patients and to investigate the associations between different forms of vascular co-morbidity and depression., Methods: Cross-sectional data were used from a primary-care sample of 1,269 insulin-naive (i.e. not using insulin therapy) diabetes patients participating in the DIAZOB Primary Care Diabetes study. Demographics, vascular co-morbidities, clinical and lifestyle characteristics, and psychosocial factors were assessed. Depression symptoms were measured with the Edinburgh Depression Scale, with a score >11 defined as depression. The chi (2) and Student's t tests were used to compare groups with and without vascular co-morbidities. Rates and odds ratios of depression were calculated for each vascular co-morbidity, with diabetes only as the reference group, correcting for age and sex. Single and multiple logistic regression analyses were performed to test a more comprehensive model regarding the likelihood of depression in diabetes., Results: The prevalence of depression was 11% in the total sample with little difference between the groups with and without any vascular co-morbidity (11.2% vs 10.0%). Single vascular co-morbidities were not associated with increased rates of depression. The final model predicting depression included: having multiple vascular co-morbidities compared with none; having less social support; having experienced a recent stressful life event; female sex; and being a smoker., Conclusions/interpretation: Rates of depression in those with one additional vascular co-morbidity did not differ from patients with diabetes only. Vascular co-morbidities were only associated with higher depression scores in case of multiple co-morbidities.

We conducted a genome-wide association study for age at natural menopause in 2,979 European women and identified six SNPs in three loci associated with age at natural menopause: chromosome 19q13.4 (rs1172822; -0.4 year per T allele (39%); P = 6.3 × 10(-11)), chromosome 20p12.3 (rs236114; +0.5 year per A allele (21%); P = 9.7 × 10(-11)) and chromosome 13q34 (rs7333181; +0.5 year per A allele (12%); P = 2.5 × 10(-8)). These common genetic variants regulate timing of ovarian aging, an important risk factor for breast cancer, osteoporosis and cardiovascular disease.

Background: Depression is a common complication of type 2 diabetes, associated with poor disease outcomes such as impaired glycaemic control, cardiovascular disease and increased mortality. The mechanisms behind these associations are unclear. Depression might contribute to poor disease outcomes through decreased physical activity., Objective: To test whether type 2 diabetes patients with elevated depression scores are more often physically inactive., Methods: Demographic features, clinical factors, level of physical inactivity and depressive symptoms were assessed in 2646 primary care patients with type 2 diabetes. Sequential multiple logistic regression analyses [odds ratio, 95% confidence interval (CI)] were performed to test the association between depressive symptoms and physical inactivity., Results: About 48% of the respondents were physically inactive. Elevated depressive symptoms were found in 14% of the respondents. After adjustment for potential confounders, the odds for being physically inactive were almost doubled in depressed patients with type 2 diabetes 1.74 (95% CI 1.32-2.31)., Conclusions: Presence of depressive symptoms almost doubles the likelihood of physical inactivity in patients with type 2 diabetes. Longitudinal studies are needed to investigate whether physical inactivity forms the link between depression and poor disease outcomes.
