Risk and protective factors for pre- and postnatal bonding.

Since disturbances in the mother-child bond increase the risk of negative consequences for child development, it is important to identify risk and protective factors for bonding as well as longitudinal associations. Previous research has used different bonding instruments during pregnancy and the postnatal phase, leading to inconsistent results. In the current study, the same instrument was used during the various phases. In a large, community-based sample (N = 793), general information, feelings of pre- and postnatal bonding (Pre- and Postnatal Bonding Scale), depressive symptoms (Edinburgh Postnatal Depression Scale), and partner support (subscale Tilburg Pregnancy/Postnatal Distress Scale) were measured at both 32 weeks of pregnancy and 8 months postnatally. Partner support was found to be a protective factor for suboptimal pre- and postnatal bonding, as was the engagement with fetal movements for prenatal bonding. High maternal educational level was a risk factor for suboptimal prenatal bonding, as were depressive symptoms for suboptimal postnatal bonding. The associations between most prenatal determinants and postnatal bonding were mediated by prenatal bonding, which underlines the importance of promoting prenatal bonding. Professionals in clinical practice should be aware of partner support, engagement with fetal movements, and postnatal depressive symptoms: All these factors offer opportunities for improving the bonding processes.

Dado que las perturbaciones en la unión afectiva entre madre y niño aumentan el riesgo de consecuencias negativas para el desarrollo del niño, es importante identificar los factores de riesgo y de protección de la unión afectiva, así como también las asociaciones longitudinales. La investigación anterior ha utilizado diferentes instrumentos para la unión afectiva durante el embarazo y la fase postnatal, lo que ha llevado a resultados inconsistentes. En el presente estudio, el mismo instrumento se usó durante las diferentes fases. En un grupo muestra grande con base comunitaria (N = 793), se midieron, tanto a las 32 semanas del embarazo como a los ocho meses después del nacimiento, la información general, los sentimientos sobre la unión afectiva pre- y postnatal (Escala de Unión Afectiva Pre- y Postnatal), los síntomas depresivos (Escala de Edimburgo de la Depresión Postnatal), y el apoyo de la pareja (Sub-escala Tilburg sobre el Embarazo / Escala de la Angustia Postnatal). Se detectó el apoyo de la pareja como un factor de protección para la unión afectiva pre- y postnatal por debajo del punto óptimo, lo cual también se dio con respecto a la interacción con los movimientos fetales en la unión afectiva prenatal. El alto nivel de educación materna fue un factor de riesgo para la unión afectiva prenatal sub-óptima, así como los síntomas depresivos lo fueron para la unión afectiva postnatal sub-óptima. Las asociaciones entre la mayoría de los determinantes prenatales y la unión afectiva postnatal fueron mediadas por la unión afectiva prenatal, lo cual subraya la importancia de promover la unión afectiva prenatal. Los profesionales de la práctica clínica deben estar conscientes del apoyo de la pareja, la interacción con los movimientos fetales, y los síntomas depresivos postnatales: todos estos factores ofrecen oportunidades de mejorar los procesos de afectividad.

Etant donné que les perturbations du lien mère-enfant augmentent le risque de conséquences négatives pour le développement de l'enfant il est important d'identifier les facteurs de risque et les facteurs de protection du lien, ainsi que les associations longitudinales. Jusqu'à présent les recherches ont utilisé divers instruments de lien durant la grossesse et la phase postnatale, menant à des résultats n'étant pas uniformes. Dans cette étude, le même instrument a été utilisé durant les phases multiples. Chez un grand échantillon représentatif de la communauté (N = 793), les renseignements généraux, les sentiments de lien pré- et postnatal (Echelle Pré- et Postnatale) les symptômes dépressifs (Echelle de Dépression Postnatale d'Edinbourg) et le soutien du conjoint (sous-échelle de grossesse Tilburg/Echelle de Détresse Postnatale) ont été mesurés à la fois à 32 semaines de grossesse et à huit mois postnatalement. Le soutien du conjoint s'est avéré être une facteur de protection pour le lien sous-optimal pré- et postnatal, tout comme l'était le fait de s'engager avec les mouvements du foetus pour le lien prénatal. Un niveau élevé d'éducation chez la mère était un facteur de risque de lien prénatal sous-optimal, tout comme l'étaient des symptômes dépressifs pour le lien sous-optimal postnatal. Les associations entre la plupart des déterminants prénataux et le lien postnatal étaient toutes influencées par le lien prénatal, ce qui souligne l'important de la promotion du lien prénatal. Les professionnels en pratique clinique devraient être vigilants quant au soutien du partenaire, au fait de s'engager avec les mouvements du foetus et aux symptômes dépressifs postnataux: tous ces facteurs offrent des possibilités d'amélioration des processus de lien.

Comorbidity of autoimmune thyroid disorders and psychiatric disorders during the postpartum period: a Danish nationwide register-based cohort study.

BACKGROUND: The postpartum period is well-known risk period for the first onset of autoimmune thyroid disorders (AITDs) as well as first onset of psychiatric disorders. These two disorders are some of the most prevalent medical conditions postpartum, often misdiagnosed and disabling if left untreated. Our study was designed to explore the possible bidirectional association between AITDs and psychiatric disorders during the postpartum period. METHODS: A population-based cohort study through linkage of Danish national registers, which comprised 312 779 women who gave birth to their first child during 1997-2010. We conducted Poisson regression analysis to estimate the incidence rate ratio (IRR) of psychiatric disorders among women with first-onset AITDs, the IRR of AITDs among women with first-onset psychiatric disorders as well as the overlap between these disorders using a comorbidity index. RESULTS: Women with first-onset AITDs postpartum were more likely to have first-onset psychiatric disorders than women who did not have postpartum AITDs (IRR = 1.88, 95% confidence interval (CI): 1.25-2.81). Women with first-onset postpartum psychiatric disorders had a higher risk of AITDs than women with no psychiatric disorders (IRR = 2.16, 95% CI: 1.45-3.20). The comorbidity index 2 years after delivery was 2.26 (95% CI: 1.61-2.90), indicating a comorbidity between first-onset AITDs and psychiatric disorders. CONCLUSIONS: First-onset AITDs and psychiatric disorders co-occur in the postpartum period, which has relevance to further studies on the etiologies of these disorders and why childbirth in particular triggers the onset.

Thyroid disease symptoms during early pregnancy do not identify women with thyroid hypofunction that should be treated.

OBJECTIVE: To evaluate whether women during early pregnancy with "hypothyroidism" symptoms are at risk of biochemically defined hypothyroidism. The 2017 Guidelines of the American Thyroid Association (ATA) recommend case-finding on the basis of symptoms to identify these women during pregnancy, while evidence is lacking. DESIGN: Construct validation of a thyroid hypofunction symptom checklist during the first trimester of pregnancy comparing high scores with biochemically defined hypothyroidism. PATIENTS: A total of 2198 healthy pregnant women from an iodine-sufficient area in 2013-2014. MEASUREMENTS: Completion of a draft questionnaire with "classical" symptoms of hypothyroidism at 12 weeks of gestation. The 2.5th and 97.5th percentiles of TSH and fT4 during pregnancy in TPO-Ab-negative (<35 kU/L) women were used to define euthyroid women and those with overt (clinical) and subclinical hypothyroidism. The prevalence of overt (subclinical) hypothyroidism was compared between women with high symptom scores and those with low symptom scores. RESULTS: According to fT4 and TSH cut-offs (0.23-4.0 mIU/L and 11.5-18.0 pmol/L, respectively), there were 15 women with "to treat hypofunction" (overt hypothyroidism or TSH >10 mIU/L) and 68 women with subclinical hypothyroidism. Questionnaire construct validation revealed a 12-item hypothyroid checklist with normally distributed scores. The cut-off indicating high scores of OH was set at 1 SD > mean. Women with high symptom scores did not present more often with biochemically defined thyroid hypofunction. CONCLUSION: This study does not support the ATA recommendation that pregnant women who require levothyroxine therapy can be identified by case-based screening of women with symptoms of thyroid disease.

Increased maternal TSH and decreased maternal FT4 are associated with a higher operative delivery rate in low-risk pregnancies: A prospective cohort study.

BACKGROUND: The increasing number of operative deliveries is a topic of major concern in modern obstetrics. Maternal thyroid function is of known influence on many obstetric parameters. Our objective was to investigate a possible relation between maternal thyroid function, and operative deliveries. Secondary aim was to explore whether thyroid function was related to specific reasons for operative deliveries. METHODS: In this prospective cohort study, low-risk Caucasian women, pregnant of a single cephalic fetus were included. Women with known auto-immune disease, a pre-labour Caesarean section, induction of labour, breech presentation or preterm delivery were excluded. In all trimesters of pregnancy the thyroid function was assessed. Differences in mean TSH and FT4 were assessed using t-test. Mean TSH and FT4 levels for operative deliveries were determined by one way ANOVA. Repeated measurement analyses were performed (ANOVA), adjusting for BMI, partiy, maternal age and gestational age at delivery. RESULTS: In total 872 women were included, of which 699 (80.2%) had a spontaneous delivery. At 36 weeks gestation women who had an operative delivery had a significantly higher mean TSH (1.63 mIU/L versus 1.46 mIU/L, p = 0.025) and lower mean FT4 (12.9 pmol/L versus 13.3 pmol/L, p = 0.007)) compared to women who had a spontaneous delivery. Mean TSH was significantly higher (p = 0.026) and mean FT4 significantly lower (p = 0.030) throughout pregnancy for women with an operative delivery due to failure to progress in second stage of labour, compared to women with a spontaneous delivery or operative delivery for other reasons. CONCLUSIONS: Increased TSH and decreased FT4 seem to be associated with more operative vaginal deliveries and Caesarean sections. After adjusting for several confounders the association remained for operative deliveries due to failure to progress in second stage of labour, possibly to be explained by less efficient uterine action.

Effectiveness of a stepped care intervention for anxiety and depression in people with diabetes, asthma or COPD in primary care: A randomized controlled trial.

BACKGROUND: Depression and anxiety are common in people with a chronic somatic disease. Although guidelines recommend stepped care, the effectiveness of this approach has not been evaluated in people with diabetes, asthma, or COPD in primary care. METHODS: 3559 People were sent screening questionnaires (41% response). Of 286 persons with anxiety and/or depression (Generalized Anxiety Disorder questionnaire, GAD-7, cut-off ≥ 8 and/or Patient Health Questionnaire, PHQ-9, cut-off ≥ 7), 46 were randomized into the intervention (stepped care and monitoring of symptoms; n = 23) or control (usual care) group (n = 23). Main outcomes were symptoms of anxiety and depression after the 12-months intervention and six months post intervention. Analysis of covariance was first adjusted for condition and baseline GAD-7/PHQ-9 scores and additionally for age, sex and education. RESULTS: The intervention group had a significantly lower level of anxiety symptoms at the end of the program (GAD-7 6 ± 6 vs. 9 ± 6; Cohen's d = 0.61). This effect was still present six months post intervention. The effect on depression was statistically significant in the first model (PHQ-9 6 ± 4 vs. 9 ± 6; p = 0.035), but not in the fully adjusted model (p = 0.099), despite a large effect size (d = 0.63). At six months post intervention there was no statistically significant difference in symptoms of depression between the two groups although the difference in symptoms was still clinically significant (Cohen's d = 0.61). LIMITATIONS: Many people were screened, but relatively few participated in the randomized controlled trial. CONCLUSIONS: Stepped care with monitoring resulted in a lower level of symptoms of anxiety and depression in people with a chronic condition.

Prevalence, course and determinants of carpal tunnel syndrome symptoms during pregnancy: a prospective study.

OBJECTIVE: To investigate the prevalence, severity and relation to fluid retention of self-reported pregnancy-related carpal tunnel syndrome (CTS) symptoms in a large sample of pregnant women. DESIGN: A prospective longitudinal cohort study. SETTING: Dutch women who became pregnant between January 2013 and January 2014 in the southeast of The Netherlands. POPULATION OR SAMPLE: A total of 639 Dutch pregnant women. METHODS: Baseline characteristics were assessed at 12 weeks' gestation. CTS symptoms were assessed using the Boston Carpal Tunnel Questionnaire (BCTQ) at 32 weeks and during the first postpartum week regarding the last weeks of pregnancy. Fluid retention, sleeping problems and depressive symptoms (using the Edinburgh Depression Scale) were assessed at several time points during pregnancy. MAIN OUTCOME MEASURES: BCTQ scores, fluid retention and sleeping problems. RESULTS: Of the 639 women, 219 (34%) reported CTS symptoms during pregnancy. Total mean scores on the BCTQ were significantly higher after 32 weeks' than up to 32 weeks' gestation. Most women experienced mild to moderate symptoms. Pregnant women with CTS symptoms reported significantly higher levels of fluid retention during gestation compared with pregnant women without CTS symptoms [F = 60.6, df (1598), P < 0.001], adjusted for body mass index (BMI), age, parity, and depression scores. Higher scores on fluid retention throughout the pregnancy were significantly related to CTS (OR = 1.8, 95%CI 1.5, 2.1, P < 0.001). Finally, the occurrence of CTS was independently related to sleeping problems. CONCLUSIONS: Although the severity of symptoms and functional impairment of CTS were relatively mild, health care professionals should be aware of the high prevalence. The occurrence of CTS symptoms is significantly higher in women who report fluid retention during gestation and it can contribute to sleeping problems.

Maternal thyrotropin is independently related to small for gestational age neonates at term.

OBJECTIVE: Small for gestational age (SGA) newborns constitute still a major cause of perinatal morbidity and mortality. Overt thyroid disease is a known cause of preterm birth and low birthweight but in its untreated condition it is rare today. In this study, we investigated the possible relation between maternal thyroid function assessed in euthyroid women at each trimester and the incidence of term born SGA neonates. DESIGN: A prospective cohort study was performed. PATIENTS: Thyroid function was assessed at 12, 24 and 36 weeks gestation in 1051 healthy Caucasian women who delivered at ≥ 37 weeks gestation. MEASUREMENTS: One-way anova was used to compare mean TSH and FT4 levels between women with SGA neonates and controls. Multiple logistic regression analysis was performed to adjust for known risk factors of SGA. RESULTS: Seventy (6·7%) SGA neonates were identified and they were significantly more often born to women with a TSH ≥ 97·5th at first and third trimester. Multiple logistic regression analysis showed that smoking (OR: 4·4, 95% CI: 2·49-7·64), pre-eclampsia (OR: 2·8, 95% CI: 1·19-6·78) and TSH ≥ 97·5th percentile (OR 3·3, 95% CI 1·39-7·53) were significantly related to SGA. Maternal FT4 levels and TPO-Ab status were not associated with SGA offspring. CONCLUSIONS: Our data show that TSH levels in the upper range of the reference interval at different trimesters (3·0-3·29 mIU/l) are independently related to an increased risk of delivering SGA neonates at term.

Pregnancy, postpartum and the thyroid: isn't it time to offer women optimal care?

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.

Maternal thyrotrophin in euthyroid women is related to meconium stained amniotic fluid in women who deliver at or over 41 weeks of gestation.

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.

Symptoms associated with an abnormal echocardiogram in elderly primary care hypertension patients.

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.

Diabetes-specific emotional distress in people with Type 2 diabetes: a comparison between primary and secondary care.

AIMS: To compare levels of diabetes distress in people with Type 2 diabetes treated in primary and secondary care and to examine demographic and clinical correlates that may explain potential differences in levels of distress between care settings. METHODS: People with Type 2 diabetes from 24 primary care practices (n = 774) and three secondary care clinics (n = 526) completed the Problem Areas In Diabetes questionnaire. Data on HbA1c levels and diabetes complications were derived from medical charts. Hierarchical ordinal regression analysis was used to investigate which correlates could explain the potential differences in level of diabetes distress between care settings. RESULTS: Diabetes distress levels and the prevalence of elevated diabetes distress were considerably lower in the participants treated in primary care (mean (SD) total diabetes distress score 8 (11); 4% of participants with a Problem Areas In Diabetes score ≥ 40) than in secondary care (mean (SD) total diabetes distress score 23 (21); 19% of participants with a Problem Areas In Diabetes score ≥ 40, P < 0.001). In addition to care setting, the following variables were also independently related to diabetes distress: younger age, ethnic minority status, using insulin, having a higher HbA1c level, having a higher BMI and the presence of neuropathy. Other diabetes complications were not independently associated with diabetes distress. CONCLUSIONS: In primary care, lower levels of diabetes distress were reported than in secondary care. The difference in diabetes distress between care settings can be largely, but not fully, explained by specific demographic and clinical characteristics. These results need to be interpreted with caution as they are based on two separate studies, but do call into question the need to screen for diabetes distress in people with Type 2 diabetes in primary care.

Psychometric properties of the Exercise Self-efficacy Scale in Dutch Primary care patients with type 2 diabetes mellitus.

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.

Prevalence of psychological distress in elderly hypertension patients in primary care.

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.

Low bone mineral density is related to high physiological levels of free thyroxine in peri-menopausal women.

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.

Effects of exercise training on quality of life, symptoms of depression, symptoms of anxiety and emotional well-being in type 2 diabetes mellitus: a systematic review.

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.

Suboptimal glycemic control in type 2 diabetes: a key role for anhedonia?

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.

Neonatal thyroid screening results are related to gestational maternal thyroid function.

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.

Maternal thyroid function during gestation is related to breech presentation at term.

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.

Associations between vascular co-morbidities and depression in insulin-naive diabetes patients: the DIAZOB Primary Care Diabetes study.

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.
