RESUMO

BACKGROUND: Pulmonary arterial hypertension (PAH; World Heath Organization [WHO] Group 1) is associated with increased pulmonary arterial pressure and resistance, with pulmonary vascular remodelling. The vascular anatomy of the systemic arteries has been less well studied. METHOD: Nineteen (19) patients with PAH, confirmed by right heart catheterisation (RHC), 14 patients with left ventricular heart failure with reduced ejection fraction (LVrEF), and 30 healthy subjects were enrolled. Common carotid artery (CCA) intima thickness, intima/media (I/M) thickness ratio, and intima-media thickness (IMT) were assessed using non-invasive ultrasound (22 MHz centre frequency). RESULTS: The CCA intima thickness was correlated with several RHC variables (all p<0.05). The intima was 56% thicker (+0.05 mm; 95% CI 0.03, 0.06; p<0.0001) and the I/M thickness ratio was 128% greater (+0.21; 95% CI 0.13, 0.28; p<0.0001) in patients with PAH than healthy subjects. These values were also significantly higher than in patients with LVrEF. In ROC curve analysis, the c-values for CCA intima thickness (0.92) and I/M ratio (0.87), but not for IMT, correctly indicated which individuals belonged to the PAH or healthy control groups. The CCA IMT showed no corresponding significant group differences or associations and was of no use according to receiver operating curve analysis. CONCLUSIONS: Patients with PAH displayed signs of peripheral vascular remodelling, challenging the common opinion that vascular changes in PAH are restricted to the lung vasculature. Correlations with cardiopulmonary variables from RHC support peripheral vascular coupling and the association with vascular ageing. Results from this pilot study warrant further confirmation.

RESUMO

Background: Obesity in adolescents is increasing worldwide and associated with an elevated cardiovascular risk later in life. In a group-comparative study, we investigated the association between adiposity in adolescents and signs of vascular aging and inflammation. Methods: Thirty-nine adolescents (10-18 years old), 19 with obesity and 20 with normal weight, were enrolled. The intima thickness and intima/media thickness ratio (I/M) were assessed using high-resolution ultrasound in the common carotid artery (center frequency 22 MHz) and the distal radial artery (RA; 50 MHz). Increased intima and high I/M are signs of vascular aging. Body characteristics, high-sensitivity C-reactive protein (hs-CRP), plasma lipids, and glycemic parameters were measured. Results: Adolescents with obesity, compared to normal-weight peers, had elevated plasma lipid, insulin c-peptide, and hs-CRP levels, the latter increasing exponentially with increasing adiposity. Obese adolescents had a thicker RA intima layer [0.005 mm; 95% confidence intervals (0.000, 0.009); P = 0.043] and a higher RA I/M [0.10; (0.040, 0.147); P < 0.0007]. Group differences for the RA I/M remained significant after adjustment for age, sex, fasting plasma insulin, and body mass index, both separately and together (P = 0.032). The RA I/M was correlated with hs-CRP, and both were correlated with the analyzed cardiovascular risk factors. Receiver operating curve c-values for RA I/M (0.86) and hs-CRP (0.90) strongly indicated correct placement in the obese or non-obese group. Conclusions: Adolescents with obesity had significantly more extensive vascular aging in the muscular RA, than normal-weight peers. The findings support an inflammatory link between obesity and vascular aging in adolescents.

RESUMO

Rapid eye movement (REM) obstructive sleep apnea might be particularly harmful to the cardiovascular system. We aimed to investigate the association between sleep apnea during REM sleep and signs of atherosclerotic disease in the form of carotid intima thickness in a community-based sample of men and women and possible sex differences in this association. The association between sleep apnea during REM sleep and intima thickness was analysed cross-sectionally in women from the community-based "Sleep and Health in Women" (SHE) study (n = 253) and age- and body mass index (BMI)-matched men from the "Men in Uppsala; a Study of sleep, Apnea and Cardiometabolic Health" (MUSTACHE) study (n = 338). Confounders adjusted for were age, BMI, gender, alcohol, and smoking. All participants underwent a full-night polysomnography, high-resolution ultrasonography of the common carotid artery, anthropometric measurements, blood pressure measurements, and answered questionnaires. There was an association between sleep apnea during REM sleep and thicker carotid intima that remained after adjustment for confounding (adjusted ß = 0.008, p = 0.032). The intima was increased by 9.9% in the group with severe sleep apnea during REM sleep, and this association between severe sleep apnea during REM sleep and increased intima thickness remained after adjustment for confounders (adjusted ß = 0.043, p = 0.021). More women than men had severe sleep apnea during REM sleep; moreover, in sex-stratified analyses, the association between sleep apnea during REM sleep and intima thickness was found in women but not in men. We conclude that severe REM sleep apnea is independently associated with signs of atherosclerosis. When stratified by sex, the association is seen in women but not in men.

RESUMO

CONTEXT: A preponderance of basic luteinizing hormone (LH) molecules having elevated bioactivity was detected in the circulation of women with polycystic ovary syndrome (PCOS). Subsequent studies have shown that LH and follicle-stimulating hormone (FSH) both circulate as glycoforms differing in number of glycans: low-N-glycosylated glycoforms, LHdi and FSHtri, with high in vitro bioactivity, and fully glycosylated glycoforms, LHtri and FSHtetra, with high in vivo bioactivity. OBJECTIVE: This work aims to characterize the glycosylation patterns on circulating gonadotropin glycoforms in women with PCOS. METHODS: Serum samples, collected from 8 women with PCOS were included. The concentration, sulfonation, and sialylation of each glycoform were determined and compared with values of serum samples from healthy women: 22 women at follicular phase, 16 at midcycle, and 15 after menopause. RESULTS: All the women with PCOS had higher LHdi serum levels compared with those in the follicular-phase group. Median LHdi and median LHtri levels were significantly elevated in PCOS women. The percentage of LHdi was increased from 37 to 49 and that of FSHtri was decreased from 41 to 33. The LHdi, LHtri, and FSHtetra glycoforms were more sialylated and both LH glycoforms less sulfonated in women with PCOS. CONCLUSION: All women with PCOS had increased serum levels of LHdi, compared with those in the follicular phase. The percentage of LHdi was increased and that of FSHtri decreased in women with PCOS. The increased LHdi leads to maintenance of the abnormal early follicular development of the polycystic ovary, and the decreased FSHtri contributes to the arrested follicle growth.

RESUMO

OBJECTIVES: Circulating concentrations of endogenous steroids have systemic implications on health in elderly. However, population-based age- and ethnicity-specific data are scarce. The aim was to report sex-specific plasma concentrations of endogenous sex and adrenal steroids in elderly Swedish Caucasians, to examine the impact of BMI and to present concentrations in apparently healthy subjects. METHODS: A population-based observational study of 70-year olds, including 684 community-dwelling men and women enrolled in the PIVUS study, Sweden. Median plasma concentrations were determined using liquid chromatography-tandem mass spectrometry (LC-MS/MS) for pregnenolone, 17-hydroxypregnenolone, 17-hydroxy-progesterone, 11-deoxycortisol, DHEA, androstenedione, testosterone, estrone and estradiol. RESULTS: Plasma concentrations were significantly higher in men (n = 452) than in women (n = 232) for estradiol: median 61.3 pmol/L (95% CI, 11.4, 142.7) vs 18.4 (4.0, 127.3), for estrone: 92.8 (33.3, 206) vs 71.6 (17.8, 209) pmol/L, and for testosterone 13.8 (5.7, 28.0) vs 0.7 (0.2, 2.0) nmol/L. Higher concentrations of estrone and estradiol were observed in obese than non-obese women. Compared to non-obese men, obese men had lower concentrations of testosterone and its precursors: 17-hydroxypregnenolone, 17-hydroxyprogesterone, androstenedione and DHEA. The subgroup of apparently healthy individuals had median values > 20% lower for estrone and estradiol in women but slightly higher for testosterone in both sexes. CONCLUSIONS: Concentrations of estradiol, estrone and testosterone were higher in 70-year-old men than in women. BMI associated positively to estradiol and estrone in women and negatively to testosterone in men. Apparently healthy women had lower median concentrations of estradiol and estrone and men had higher median testosterone compared to all individuals.

RESUMO

OBJECTIVES: Asymmetric- and symmetric dimethylarginines (ADMA, SDMA) are elevated in cardiovascular disease (CVD). Preeclampsia is a pregnancy-specific syndrome and is an independent risk factor for subsequent CVD. Aims were to investigate whether ADMA, SDMA levels and l-arginine/ADMA and l-arginine/SDMA ratios during pregnancy and their changes from pregnancy to postpartum are associated to arterial wall layer dimensions and cardiovascular risk factors in women with and without preeclampsia. STUDY DESIGN: Dimethylarginines were analyzed by LC-MS, and the common-carotid-artery (CCA) intima and media thicknesses were estimated using 22-MHz non-invasive ultrasonography in women with preeclampsia (cases = 48) and normal pregnancies (controls = 58) in similar gestational age, with reassessment one-year postpartum. A thick intima, thin media and high intima/media ratio (I/M) indicates a less healthy arterial wall. RESULTS: The median age of cases and controls was 30 years. During pregnancy, women with preeclampsia had higher plasma ADMA, SDMA and lower l-arginine/ADMA and l-arginine/SDMA (all p < 0.01) than women with normal pregnancies. Further, ADMA, SDMA, l-arginine/ADMA and l-arginine/SDMA correlated to intima thickness (rs = 0.33/0.33/-0.33/-0.35 and p < 0.01), I/M (rs = 0.26/0.28/-0.22/-0.26 and p < 0.05) and mean arterial pressure (MAP) (rs = 0.43/0.42/-0.39/-0.40 and p < 0.0001). Changes in ADMA, SDMA and l-arginine/SDMA from pregnancy to postpartum correlated to changes in intima thickness (rs = 0.22/0.32/-0.21 and p < 0.05/<0.01/<0.05), I/M (rs = 0.22/0.31/0.08 and p < 0.05/<0.01/=0.43) and MAP (rs = 0.31/0.53/-0.25 and p < 0.01/<0.001/<0.05). No correlations were found for conventional CCA intima-media-thickness. CONCLUSIONS: Dimethylarginines were associated to signs of adverse effects on arterial wall layer dimensions and cardiovascular risk factors in women with and without preeclampsia, during pregnancy and to their changes from pregnancy up to one-year postpartum.

RESUMO

OBJECTIVE: Early-onset psychosis (EOP) and bipolar disorder (EOBP) (at <18 years of age), are associated with an increased future risk of cardiovascular disease (CVD) and premature death. Yet it is unknown whether the arteries show visible signs of atherosclerosis in EOP and EOBP. This study investigated whether having EOP or EOBP was associated with detectable signs of preclinical atherosclerosis. METHOD: By using 22 MHz high-frequency ultrasound, different layers of the arterial wall of the left common carotid artery (LCCA) were assessed in 77 individuals with EOP (n = 25), EOBP (n = 22), and in age-matched healthy controls (n = 30). Conventional CVD confounders were included in the analyses. RESULTS: Adolescents with EOP and EOBP, compared to controls, had a significantly thicker LCCA intima thickness (0.132 vs. 0.095 mm, p < .001) and intima/media ratio (0.24 vs. 0.17 p < .001). There was a nonsignificant intima difference between EOP and EOBP. Conventional CVD risk factors did not explain the association between EOP/EOBP and intima thickness. In the group of EOP/EOBP, there was a significant correlation between the dose of current antipsychotic medication and intima thickness; however, the correlation was attenuated to a nonsignificant level when adjusted for global function. CONCLUSIONS: Adolescents with EOP or EOBP had an increased LCCA intima thickness, interpreted as a sign of preclinical atherosclerosis. Global function of the disorders was the strongest determinant of intima thickness. The findings, if replicated, might have implications for long-term treatment of EOP and EOBP in order to reduce a future risk of CVD.

RESUMO

BACKGROUND AND AIMS: Pre-eclampsia is associated with increased risk of cardiovascular disease and premature death. However, conventional common carotid artery intima-media thickness (CCA-IMT) measurement does not reflect this. In contrast, measurement of the individual CCA intima and media thicknesses clearly indicates increased vascular risk both at diagnosis and about one year after pre-eclampsia. This study examined whether individual CCA wall layers, risk factors for cardiovascular disease, and markers of endothelial dysfunction had normalized or remained unfavorable seven years after pre-eclampsia. METHODS: The individual CCA intima and media thicknesses were measured using 22 MHz ultrasound. Conventional cardiovascular risk factors were recorded. A thick intima, thin media and high intima/media thickness ratio (I/M) are signs of sub-clinical atherosclerosis. RESULTS: The median age of women with previous pre-eclampsia (cases = 23) or normal pregnancies (controls = 35) was 39/37 years. At follow-up (median about seven years), the intima remained thicker and the I/M was higher in cases than in controls [all p < 0.0001; p < 0.001 after adjustment for time to follow-up, body mass index (BMI), and mean arterial pressure (MAP)], whereas the CCA-IMT was illogically thinner. Further, BMI, MAP, hip circumference, abdominal height, serum endostatin and apolipoprotein B levels were higher in cases (all p < 0.05). Intima and I/M measurements were correlated with age, MAP, endostatin and apolipoprotein B, whereas no logical correlations were found for CCA-IMT. CONCLUSIONS: The arteries in cases but not controls were still adversely affected after seven years. Measuring intima thickness and I/M appears preferable to measuring CCA-IMT for demonstrating vascular risk after pre-eclampsia.

RESUMO

Study Objectives: Although obstructive sleep apnea (OSA) is associated with overall cardiovascular disease and mortality, the association with atherosclerotic cardiovascular disease is less clear, especially in women. Recently, it has been suggested that OSA during rapid eye movement (REM) sleep, associated with long apneas and deep desaturations, could have severe cardiometabolic consequences. The aim of this study was to investigate whether OSA during REM sleep is associated with early signs of atherosclerosis in a population-based sample of women. Methods: In the community-based "Sleep and Health in Women" (SHE) cohort study, 400 women underwent polysomnography, anthropometric measurements, blood sampling, blood pressure measurement, and answered questionnaires. Ten years later, 201 of the original participants, free of known atherosclerotic disease at baseline and without continuous positive airway pressure treatment for OSA, underwent a high-frequency ultrasound of the common carotid artery to assess the individual thickness of the layers of the artery wall. Results: Severe OSA during REM sleep (REM apnea-hypopnea index [AHI] ≥ 30) was associated with a thicker intima. This association was still significant after adjustment for age, body mass index, alcohol, and smoking, as well as for further adjustment for systolic blood pressure, low-density lipoprotein, C-reactive protein, and diabetes (ß-coefficient, 0.008; p-value, 0.022). The association between a REM AHI of ≥30 and intima thickness was also seen in women with no or mild OSA and normal non-REM AHI. Conclusions: In this study of a community-based sample of women, severe OSA during REM sleep was independently associated with early signs of atherosclerosis.

RESUMO

OBJECTIVES: Our purpose was to study whether there is a difference in self-rated health-related quality of life (HRQOL) and changes in HRQOL perception after 3 months of hormonal contraceptive use in adolescents. Seasonal variations in symptoms of depression were also studied. METHODS: A test group (T1) (n = 193) and a selected control group (n = 238) of women aged 14-20 years who were visiting a young person's clinic completed the 36-item short-form health survey (SF-36) and answered additional questions on menstrual history and pattern, need for menstrual pain relief medication, and other regular medication. The test group was reassessed after 3 months of hormonal contraception (T2). Seasonal variations in reported SF-36 scores were studied for the whole group. RESULTS: The selected control group and test group at T1 were similar with regard to age at menarche and menstrual pattern. The duration of bleeding and use of painkillers were significantly reduced and the impact on everyday life was significantly improved after 3 months of hormonal contraception (p = .000, two-tailed). No changes in HRQOL or symptoms of possible depression were found after 3 months of hormonal contraception. The highest prevalence odds ratio for possible depression (SF-36 mental health scale score ≤48), adjusted for group, season and age, for spring vs winter, was 2.15 (95% confidence interval 0.95, 4.85). CONCLUSIONS: After 3 months of hormonal contraception both the number of days of menstrual bleeding and the use of medication to relieve menstrual pain were reduced, but there were no significant changes in self-rated HRQOL perception. Seasonal effects on HRQOL were reported.

RESUMO

BACKGROUND: Preeclampsia (PE) in pregnancy is a state of exaggerated inflammation and is associated with an increased risk of cardiovascular disease (CVD) later in life. Levels of pentraxin 3 (PTX3), a novel inflammation marker, are increased during PE and in individuals with CVD. The primary aim of this study was to assess whether serum PTX3 in women with PE is associated with adverse arterial effects; a thicker intima and higher intima/media (I/M) ratio in the common carotid artery (CCA). METHODS: Serum PTX3 levels were measured using commercially available enzyme-linked immunosorbent assay kits, and individual CCA intima and media thicknesses were estimated by 22MHz non-invasive ultrasound in 55 women at PE diagnosis and 64 women with normal pregnancies at a similar gestational age, and about one year postpartum. A thick intima, thin media and high I/M ratio indicate a less healthy artery wall. RESULTS: During pregnancy serum PTX3 correlated positively with intima thickness and I/M ratio but negatively with media thickness (all p<0.0001), indicating adverse arterial effects. About one year postpartum, PTX3 levels had decreased in both groups and there remained no significant group difference or significant correlation with CCA wall layers. CONCLUSIONS: Higher levels of serum PTX3 in women with PE were significantly associated with signs of adverse arterial effects during pregnancy, but not one year postpartum, supporting the rapid dynamics of PTX3.

RESUMO

STUDY OBJECTIVE: To investigate potential quantitative and qualitative differences in brain serotonergic activity between women with Premenstrual Dysphoria (PMD) and asymptomatic controls. BACKGROUND: Serotonin-augmenting drugs alleviate premenstrual mood symptoms in the majority of women with PMD while serotonin-depleting diets worsen PMD symptoms, both indicating intrinsic differences in brain serotonergic activity in women with PMD compared to asymptomatic women. METHODS: Positron-emission tomography with the immediate precursor of serotonin, 5-hydroxytryptophan (5-HTP), radiolabelled by 11C in the beta-3 position, was performed in the follicular and luteal phases for 12 women with PMD and 8 control women. Brain radioactivity-a proxy for serotonin precursor uptake and synthesis-was measured in 9 regions of interest (ROIs): the right and left sides of the medial prefrontal cortex, dorsolateral prefrontal cortex, putamen and caudate nucleus, and the single "whole brain". RESULTS: There were no significant quantitative differences in brain 5-HTP-derived activity between the groups in either of the menstrual phases for any of the 9 ROIs. However, multivariate analysis revealed a significant quantitative and qualitative difference between the groups. Asymptomatic control women showed a premenstrual right sided relative increase in dorsolateral prefrontal cortex 5-HTP derived activity, whereas PMD women displayed the opposite (p = 0.0001). Menstrual phase changes in this asymmetry (premenstrual-follicular) correlated with changes in self ratings of 'irritability' for the entire group (rs = -0.595, p = 0.006). The PMD group showed a strong inverse correlation between phase changes (premenstrual-follicular) in plasma levels of estradiol and phase changes in the laterality (dx/sin) of radiotracer activity in the dorsolateral prefrontal ROI (rs = -0.635; 0.027). The control group showed no such correlation. CONCLUSION: Absence of increased premenstrual right-sided relative 5-HTP-derived activity of the dorsolateral prefrontal cortices was found to strongly correlate to premenstrual irritability. A causal relationship here seems plausible, and the findings give further support to an underlying frontal brain disturbance in hormonally influenced serotonergic activity in women with PMD. Because of the small number of subjects in the study, these results should be considered preliminary, requiring verification in larger studies.

RESUMO

BACKGROUND: There is evidence of cerebral involvement among women with preeclampsia. Levels of the cerebral biomarkers neuron-specific enolase (NSE) and S100B are elevated during pregnancy in women developing preeclampsia. It is although not known if these biomarkers return to normal range postpartum. The aim with this study was to compare levels of S100B and NSE during pregnancy and 1 year postpartum in women who have had preeclampsia to women with normal pregnancies. METHODS: This study was a longitudinal study of cases (n = 53) with preeclampsia and controls (n = 58) consisted of normal pregnant women in matched gestational weeks. Plasma samples were collected at inclusion during pregnancy and 1 year postpartum. Plasma samples were analyzed for levels of S100B and NSE by enzyme-linked immunosorbent assays kits. RESULTS: Levels of NSE and S100B in women with preeclampsia were higher during pregnancy than in women with normal pregnancies. One year postpartum, women who have had preeclampsia still had a higher median level of both NSE (5.07 vs. 4.28 µg/l, P < 0.05) and S100B (0.07 vs. 0.06 µg/l, P < 0.05) compared to women with previous normal pregnancies. High levels of NSE and S100B postpartum remained associated with previous preeclampsia after adjustment for confounding factors. Levels of NSE correlated to S100B during pregnancy and postpartum. CONCLUSIONS: Levels of NSE and S100B are still elevated 1 year postpartum in women who have had preeclampsia in contrast to women with previous normal pregnancies. We hypothesize that there might be a persistent cerebral involvement among women with preeclampsia even 1 year postpartum.

RESUMO

OBJECTIVE: To investigate if topical oxytocin can reverse vaginal atrophy, as assessed by cytological and histological examination of the vaginal mucosal epithelium, in postmenopausal women after 12 weeks of treatment as compared to placebo. STUDY DESIGN: Sixty-eight postmenopausal women diagnosed with vaginal atrophy were randomized for this multicenter, double-blinded, placebo-controlled trial. Thirty-three women received 600 IU vagitocin, an oxytocin containing gel, and 35 women received a placebo gel intravaginally. The dose was 600 IU daily for the first two weeks and thereafter 600 IU twice a week for 10 weeks. All participant women underwent four visits and a subgroup of 20 women had a further fifth visit. Vaginal smears for cytological evaluation were collected at all visits. Vaginal biopsies were taken in 20 women before and after 12 weeks of treatment for histological analysis. In these women a vaginal smear was also collected after 14 weeks. RESULTS: The increase in the percentage of superficial cells between 0 and 2 weeks was significantly greater after treatment with vagitocin in comparison with placebo (p = 0.04). The difference in the maturation value between 0 and 12 weeks was significantly higher in the vagitocin than in the placebo group (p = 0.01). The reduction in the scores of atrophy was according to the histological investigation significantly greater in the vagitocin group than in the placebo group at 12 weeks (p < 0.04). CONCLUSION: Daily intravaginal treatment with vagitocin 600 IU improves expressions of vaginal atrophy as recorded by cytological investigation of vaginal smears and histological analysis of vaginal biopsies. Treatment twice weekly seems to be less effective regarding the increase in superficial cells.

RESUMO

Steroid concentrations in stimulated follicular fluid (sFF) samples have been linked to the quality of oocytes used in IVF treatments. Most of the published studies focused on evaluating the association of the IVF outcomes with only a few of the steroids, measured by immunoassays (IA). We performed a treatment outcome, prospective cohort study using stimulated FF sampled from 14 infertile women undergoing IVF treatment; single oocyte was used per IVF cycle. Fourteen endogenous steroids were analyzed in 22 ovarian follicle aspirations, which corresponded to the embryos used in the IVF. Ten oocytes were associated with live birth (LB) and 12 with no pregnancy (NP). Steroids were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods. Differences in distribution of concentrations in association with the pregnancy outcome (LB or NP), and receiver operating characteristic (ROC) curves analysis were performed for the entire cohort and for within-women data. The predominant androgen and estrogen in stimulated sFF were androstenedione (A4) and estradiol (E2), respectively. Lower concentrations of pregnenolone (Pr), lower ratios of A4/ dehydroepiandrosterone (DHEA), testosterone (Te)/DHEA, and greater ratios of E2/Te, and estrone/A4 were observed in sFF samples associated with LB. Among the oocytes associated with NP, in four out of 12 samples total concentration of androgens was above the distribution of the concentrations in the oocytes corresponding to the LB group. Observations of the study indicated increased consumption of precursors and increased biosynthesis of estrogens in the follicles associated with LB. Our data suggest that potentially steroid profiles in sFF obtained during oocyte retrieval may serve as biomarkers for selection of the best embryo to transfer after IVF.

RESUMO

BACKGROUND: S100B is supposed to be a peripheral biomarker of central nervous system (CNS) injury. The purpose of this study was to compare levels of S100B in women with preeclampsia with levels in healthy pregnant control subjects and furthermore to analyze levels of S100B in relation to possible CNS effects. METHODS: A cross-sectional case-control study in antenatal care centers in Uppsala, Sweden, was performed. Fifty-three women with preeclampsia and 58 healthy pregnant women were recruited at similar gestational length; women with preeclampsia were recruited at time of diagnosis, and control subjects were recruited during their routine visit to an antenatal clinic. Plasma samples were collected, and levels of S100B were analyzed with an enzyme-linked immunosorbent assay. Information about demographic and clinical characteristics, including symptoms related to CNS affection, was collected from the medical records. The main outcome measures were plasma levels of S100B and possible CNS effects. RESULTS: Levels of S100B were significantly higher among women with preeclampsia than among control subjects (0.12 µg/L vs. 0.07 µg/L; P < 0.001). In preeclampsia, there was a significant association between high levels of S100B and visual disturbances (P < 0.05). CONCLUSIONS: S100B is increased among women with preeclampsia, and high levels of S100B associate with visual disturbances, which might reflect CNS affection in women with preeclampsia.

RESUMO

OBJECTIVES: To study seasonal variations in self-rated health and depressive symptoms in adolescent girls and possible differences in reported health with regard to use of medications. METHOD: The SF-36 questionnaire was completed by 1250 girls with a mean age of 17 years, who visited a health centre in the course of one year. From January to July inclusive, depressive symptoms in 453 of the participants were also assessed using MADRS-S. Age and regular medication data were recorded. RESULTS: Significantly better mental health and less depressive symptoms were reported during the summer, than in winter months. Seasonality was more related to the SF-36 mental, than physical health subscales. Respondents treated with hormonal contraceptives (HCs) only and those not taking any medication scored better on several SF-36 subscales, than girls on antidepressives and other medications. Respondents taking HCs tended to report better physical health and less depressive symptoms on MADRS-S than those taking no medication. CONCLUSIONS: Adolescent girls showed seasonal variations in self-reported health and depressive symptoms, with more symptoms during winter months. HC users tended to report better physical health and less depressive symptoms than those on no medication. The high prevalence of suspected depression during the winter months deserves attention.

RESUMO

BACKGROUND: Preeclampsia (PE) is associated with increased risk of cardiovascular disease later in life. Ultrasound assessment of the common carotid artery intima-media thickness (IMT) during or after PE has not indicated any increased cardiovascular risk. METHODS AND RESULTS: We used high-frequency ultrasound (22 MHz) to estimate the individual common carotid artery IMTs in 55 women at PE diagnosis and in 64 women with normal pregnancies at a similar stage. All were re-examined about 1 year postpartum. A thick intima, thin media, and high intima/media (I/M) ratio are signs of a less healthy artery wall. PE was associated with a significantly thicker mean common carotid artery intima, thinner media, and higher I/M ratio than in normal pregnancy (mean I/M difference, 0.21; 95% confidence interval, 0.17-0.25; P<0.0001). After adjustment for first trimester body mass index and mean arterial pressure, differences in intima thickness and I/M remained significant. About 1 year postpartum, these values had improved in both groups, but group differences remained significant (all adjusted P<0.0001). There were no significant differences in IMT between groups. In receiver-operating characteristic curve analysis, intima thickness and I/M were strongly predictive of prevalent PE (area under the curve, ≈0.95), whereas IMT was not (area under the curve, 0.49). CONCLUSIONS: The arteries of women with PE were negatively affected during pregnancy and 1 year postpartum compared with women with normal pregnancies, indicating increased cardiovascular risk. Estimation of intima thickness and I/M ratio seem preferable to estimation of common carotid artery IMT in imaging cardiovascular risk in PE. Results from this pilot study warrant further confirmation.

RESUMO

The vascular effects of normal pregnancy were investigated by estimating the intima and media thicknesses of the common carotid artery separately using 22-MHz ultrasound (Collagenoson, Meudt, Germany) in 57 healthy women with normal pregnancies and pregnancy outcomes, in all three trimesters and at 1 yr postpartum. A thick intima, thin media, and high intima-to-media (I/M) ratio are signs of a less healthy artery wall. Mean artery wall layer dimensions remained fairly constant during pregnancy, but the intima thickness and I/M thickness ratio appeared to improve (decrease) postpartum (P < 0.001 for both). The cardiovascular risk parameters of age, body mass index, and blood pressure in the first trimester were associated with higher I/M ratios, especially in the second trimester, whereas higher serum estradiol levels were significantly associated with a lower I/M ratio. Changes from the first to second trimesters in I/M ratio, taking into account differential changes in intima and media thickness, were significantly (P < 0.05-0.001) associated with all risk parameters tested except age, which was associated with increased intima thickness (P = 0.02). Associations with third trimester values and changes from first to third trimesters were similar but less apparent. Thus, fairly constant mean artery wall layer dimensions during pregnancy appeared to improve postpartum. However, higher age, body mass index, or blood pressure and lower serum estradiol levels in the first trimester appeared to negatively affect the artery wall, strongly suggesting that pregnancy has negative vascular effects in some women. A less likely explanation involves possible adaptation to physiological changes during and after pregnancy.

RESUMO

Controlled ovarian hyperstimulation is performed to assist with generation of multiple mature oocytes for use in in vitro fertilization (IVF). The goal of our study was to evaluate differences in protein and steroid profiles in ovarian follicular fluid (hFF) samples obtained during oocyte retrieval from women undergoing IVF treatment and to identify physiological pathways associated with the proteins. The hFF samples were depleted of abundant proteins, fractionated by ultrafiltration, digested, and analyzed by nano-LC-QTOF. Concentrations of 15 endogenous steroids were determined in the samples using LC-MS/MS methods. The total number of proteins identified in the samples was 75, of which 4, 7, and 2 were unique to the samples from women with viable pregnancy, miscarriage, and no pregnancy, respectively. Identified proteins were associated with the acute response signaling, coagulation system, intrinsic and extrinsic prothrombin activation, complement system, neuroprotective role of THOP1, FXR/RXR activation, role of tissue factor, and growth hormone pathways. A greater number of proteins associated with biosynthesis was found in hFF samples corresponding to the oocytes resulting in pregnancy. The abundance of seven proteins was found to be associated with steroidogenesis. The obtained data will contribute to better understanding of the pathogenesis and development of noninvasive markers for assessment of oocytes viability.
