Postpartum depression in women with epilepsy versus women without epilepsy.

The goal of this study was to determine if there is a significant difference in the rate of postpartum depression among patients with epilepsy and healthy controls. All patients were recruited from the Epilepsy Center and the Department of Obstetrics and Gynecology, University of Milan, St. Paolo Hospital (Milan, Italy). Thirty-five pregnant women with epilepsy and an equal number of pregnant women without epilepsy were assessed with the Edinburgh Postnatal Depression Scale (EPDS), a clinical interview used to screen for postpartum depression (PPD), and a sociodemographic questionnaire. The rate of PPD in patients with epilepsy was statistically significantly higher than that of the controls (P<0.05). PPD was present in 29% of the patients with epilepsy and 11% of the controls. In conclusion, it is very important to point out that in our pilot study, the rate of PPD was higher among women with epilepsy than among women without epilepsy. In this regard, women at higher PPD risk can be identified earlier and treated as soon as possible to alleviate their symptoms and improve their quality of life.

Cathodic electrodeposition of ceramic and organoceramic materials. Fundamental aspects.

Electrodeposition of ceramic materials can be performed by electrophoretic (EPD) or electrolytic (ELD) deposition. Electrophoretic deposition is achieved via motion of charged particles towards an electrode under an applied electric field. Electrolytic deposition produces colloidal particles in cathodic reactions for subsequent deposition. Various electrochemical strategies and deposition mechanisms have been developed for electrodeposition of ceramic and organoceramic films, and are discussed in the present article. Electrode-position of ceramic and organoceramic materials includes mass transport, accumulation of particles near the electrode and their coagulation to form a cathodic deposit. Various types of interparticle forces that govern colloidal stability in the absence and presence of processing additives are discussed. Novel theoretical contributions towards an interpretation of particle coagulation near the electrode surface are reviewed. Background information is given on the methods of particle charging, stabilization of colloids in aqueous and non-aqueous media, electrophoretic mobility of ceramic particles and polyelectrolytes, and electrode reactions. This review also covers recent developments in the electrodeposition of ceramic and organoceramic materials.

Effects of contrast medium on left ventricular pressure and volume with emphasis on coronary artery disease.

Forty-one patients had left ventricular angiography repeated 3 minutes after an initial study in order to evaluate the effect of angiographic contrast medium on left ventricular end-diastolic pressure (EDP) and volume (EDV). Seven patients had no evidence of heart disease (normal group) and 34 patients had coronary artery disease. Single-vessel diseae was present in 10, double-vessel disease in 10, and triple-vessel disease in 14 patients. Seven other patients with radiopague epicardial clips previously attached to the left ventricle underwent cinefluorographic studies to determine end-diastolic intraclip distance at various intervals after a left ventricular angiogram. In all the groups studied there was a significant increase (p less than 0.005) in both the left ventricular EPD and EDV in the second angiographic study as compared to the first. This increase in EDV (deltaV) was similar in all groups. However, the increase in EDP (deltaP) was significantly greater (p less than 0.01) in patients with double- and triple-vessel disease as compared to the normal and single-vessel disease groups. Ejection fraction, per cent shortening of the heart axis, and contractile pattern in the normal subjects were not singnificantly different when the second angiographic study was compared to the first. In nine of 34 patients with coronary artery disease the second angiographic study demonstrated impairment in left ventricular contractile pattern not present in the first angiographic study. Cinefluorographic study demonstrated an increase in end-diastolic intraclip distance after the left ventricular angiogram. The change in intraclip distance corresponded directionally and temporally to the changes in left ventricular EDP. The present study revealed that the increase in left ventricular end-diastolic press-re associated with the injection of angiographic contrast medium can be explained by an increase in EDV and that such changes last for over 15 minutes and may be associated with alterations in the contractile pattern of the left ventricle.

Detecting mental disorders in general hospitals by the SCL-8 scale.

OBJECTIVE: The objective of this study is to validate the eight-item dichotomised version of the Symptoms Check List (SCL-8d) as a screening tool for psychiatric disorders. METHODS: The study population included 198 consecutive new neurological inpatients and outpatients and 294 consecutive internal medical inpatients, aged 18 or older. All patients received the SCL-8d questionnaire, and a stratified subsample was interviewed using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) interview. We tested the external SCL-8d validity using the SCAN interview as gold standard. The test was performed based on weighted data to correct for the skewness introduced by stratification. RESULTS: The diagnostic performance of the SCL-8d was excellent in the internal medical setting but not quite as good in the neurological sample. It performed better among the older compared with the younger patients, whereas the scale was not affected by gender. In the combined sample at the cut point 0/1, the sensitivity (SE) of the SCL-8d was 0.73 (confidence interval [CI](95%): 0.60-0.82), the specificity (SP) 0.61 (CI(95%): 0.53-0.68) and the positive predictive value (PPV) 0.42 (CI(95%): 0.34-0.50), using any International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) psychiatric disorder, excluding somatoform and substance abuse disorders, as gold standard. The risk of a patient having a mental disorder (except phobia, substance abuse or somatoform disorder) was less than 6% in case of a negative screening test. In patients with a current depressive disorder, 87.1% (27/31) were screening positive, and all except 1 (93.0%) of the 14 patients with a modest to severe depression scored 1 or higher on the SCL-8d. All 17 patients with an anxiety disorder, excluding phobias, were screening positive. CONCLUSION: The study suggests that the SCL-8d is a valid, brief screening tool for use in nonpsychiatric medical settings, especially to detect emotional psychiatric disorders (EPDs).

Attitudes toward motherhood in postnatal depression: development of the Maternal Attitudes Questionnaire.

This article describes the development of the Maternal Attitudes Questionnaire (MAQ), a 14-item self-report instrument measuring cognitions relating to role change, expectations of motherhood, and expectations of the self as a mother in postnatal women. This questionnaire was found to have good test-retest and internal reliability. In a large sample of women (n = 483) at 6-8 weeks postpartum, scores on the questionnaire were highly correlated with scores on the Edinburgh Postnatal Depression Scale (EPDS) and the Revised Clinical Interview Schedule (CIS-R). Cluster analysis demonstrated that, among depressed women with similar symptom scores on the CIS-R, the MAQ discriminated a group with low MAQ scores and a group with high MAQ scores. This finding supports the hypothesis that women who are depressed postnatally are cognitively heterogeneous; such differences may be important in understanding the etiology and determining the treatment of postnatal depression.

Arsenic removal using steel manufacturing byproducts as permeable reactive materials in mine tailing containment systems.

Steel manufacturing byproducts were tested as a means of treating mine tailing leachate with a high As concentration. Byproduct materials can be placed in situ as permeable reactive barriers to control the subsurface release of leachate from tailing containment systems. The tested materials had various compositions of elemental Fe, Fe oxides, Ca-Fe oxides and Ca hydroxides typical of different steel manufacturing processes. Among these materials, evaporation cooler dust (ECD), oxygen gas sludge (OGS), basic oxygen furnace slag (BOFS) and to a lesser degree, electrostatic precipitator dust (EPD) effectively removed both As(V) and As(III) during batch experiments. ECD, OGS and BOFS reduced As concentrations to <0.5mg/l from 25mg/l As(V) or As(III) solution in 72 h, exhibiting higher removal capacities than zero-valent iron. High Ca concentrations and alkaline conditions (pH ca. 12) provided by the dissolution of Ca hydroxides may promote the formation of stable, sparingly soluble Ca-As compounds. When initial pH conditions were adjusted to 4, As reduction was enhanced, probably by adsorption onto iron oxides. The elution rate of retained As from OGS and ECD decreased with treatment time, and increasing the residence time in a permeable barrier strategy would be beneficial for the immobilization of As. When applied to real tailing leachate, ECD was found to be the most efficient barrier material to increase pH and to remove As and dissolved metals.

Human exposure to respirable suspended particulate and airborne lead in different roadside microenvironments.

The aim of this study is to evaluate the particulate air pollution in selected roadside microenvironments of Hong Kong through an intensive field study dated from January 1997 to February 1997. The study employed the microenvironment monitoring technique to access the exposure of pedestrians to respirable suspended particulate and airborne lead (Pb) at heavily trafficked roadsides. A total of 62 roadside sites in 14 districts covering the most urbanized and densely populated areas were selected. It was found that pedestrians were exposed to a 24 h average of respirable suspended particulate, PM10, and airborne Pb (APb), typically ranged from 25.56 to 337.40 microg/m3 and 70.71 to 285.71 ng/m3, respectively. The average PM10 concentrations at different roadside microenvironments corresponding to urban residential, urban commercial, urban industrial and new town areas were 91.84, 129.08, 83.83, and 118.89 microg/m3 respectively. The corresponding values for APb were 130.01, 143.40, 127.40 and 173.17 ng/m3, respectively. It was found that measurement at EPD nearby rooftop monitoring stations might not reflect the actual roadside PM10 exposure. Most APb field study data was significantly higher than the nearby fixed station data.

The application of standard methods for the determination of toxaphene in environmental media.

In the United States, it is necessary to analyze for toxaphene using approved, validated methods acceptable to the regulatory agencies. As a result of an interlaboratory study and technical exchanges among the US EPA Region IV (EPA), the State of Georgia Environmental Protection Division (EPD), and Hercules Incorporated, guidelines for the application of SW-846 Method 8080 were developed. Results of analyses for sludge, soil, and water samples agreed within a percent relative standard deviation (% RSD) range of 6.9-20%. Through continued technical interchanges, guidance for the application of SW-846 Method 8081 has been developed. The results of analyses of fourteen split samples of soil and sediment produced a percent relative standard deviation that ranged from 1.6% to 127%, with an average of 38%. When two unusually divergent results were removed from consideration, the average % RSD reduced to 26%. The results of analyses of split samples show agreement between the EPA laboratory and a Hercules contract laboratory. Therefore, the guidance has achieved its purpose of producing agreement among data from different laboratories so that data reviewers may have assurance that the analytical method has been applied correctly and consistently for the determination of toxaphene in environmental samples.

Paternal depression in the postnatal period and child development: a prospective population study.

BACKGROUND: Depression is common and frequently affects mothers and fathers of young children. Postnatal depression in mothers affects the quality of maternal care, and can lead to disturbances in their children's social, behavioural, cognitive, and physical development. However, the effect of depression in fathers during the early years of a child's life has received little attention. METHODS: As part of a large, population-based study of childhood, we assessed the presence of depressive symptoms in mothers (n=13,351) and fathers (n=12,884) 8 weeks after the birth of their child with the Edinburgh postnatal depression scale (EPDS). Fathers were reassessed at 21 months. We identified any subsequent development of behavioural and emotional problems in their children (n=10,024) at age 3.5 years with maternal reports on the Rutter revised preschool scales. FINDINGS: Information was available for 8431 fathers, 11,833 mothers, and 10,024 children. Depression in fathers during the postnatal period was associated with adverse emotional and behavioural outcomes in children aged 3.5 years (adjusted odds ratio 2.09, 95% CI 1.42-3.08), and an increased risk of conduct problems in boys (2.66, 1.67-4.25). These effects remained even after controlling for maternal postnatal depression and later paternal depression. INTERPRETATION: Our findings indicate that paternal depression has a specific and persisting detrimental effect on their children's early behavioural and emotional development.

Postpartum depression and mother-infant relationship at 3 months old.

BACKGROUND: This paper is part of a prospective, epidemiologic study concerning postpartum depression (PPD). The women were first examined during pregnancy; after delivery they were seen with their infants at 3 and 18 months. The present study focuses on the 3-months-postpartum results. METHODS: A sample of 570 women and their infants were examined 3 months after delivery. Using the EPDS (Edinburgh Postnatal Depression Scale; Cox et al., 1987. Br. J. Psychiatry 150:782-786), 10.2% of these new mothers presented PPD. The focus of the study concerned the effects of this neurotic disorder on the mother, the infant and on the mother-infant relationship. RESULTS: The deleterious effects concerning the infant were functional disorders such as eating or sleeping difficulties. The 'depressed' dyads presented less vocal and visual communications, less corporal interactions and less smiling. Conditions surrounding delivery and tiredness at 3 months are linked to difficulties in mother-infant relationship for the non-depressed mothers. Logistic models showed that primiparous PPD mothers have difficulties bathing their infants, whereas multiparous PPD mothers are more tired. LIMITATION: This study did not take into account either protective factors or the effects of the infant himself. CLINICAL RELEVANCE: Knowledge of the mothers' and infants' difficulties may help caregivers to detect these at-risk dyads and initiate therapeutic measures.

Seasonal variation in postnatal depression.

BACKGROUND: We evaluated the occurrence of postnatal depression in general and during different seasons as part of a larger longitudinal mother-child follow-up study. METHOD: One hundred and eighty-five mothers, from the maternity wards of University Hospital of Oulu, Finland, completed a self-rating depression scale, the Edinburgh Postnatal Depression Scale (EPDS) twice: first at hospital 2-7 days after delivery and the second time at home 4 months after the delivery. Different psychosocial variables were mapped out to avoid any confounding factors. The year was divided in two separate ways: first, three different time periods were selected by the amount of sunlight: dark (October-January), intermediate (February, March, August, September) and light (April-July), and second, the year was divided by seasons. The results were analysed by the chi(2)-test for multinomials. RESULTS: Sixteen percent (16.2) of mothers were scored as being depressed using 13 as a cut-off point immediately after the infant was born. Thirteen percent (13.0) were depressed measured 4 months postpartum. There was more mild depression in the autumn (ratio observed/expected 1,62; 95% confidence interval 1.05-2.19) immediately after delivery, using 10 as a cut-off, and less depression in the spring (0.27; 0.00-0.62) measured at home later, using 13 as a cut-off. When using classification by the amount of light there was more depression during the dark time (1.58; 1.05-2.11) immediately postpartum. LIMITATIONS: The group sizes and the amount of sample sizes collected within each month are quite small. CONCLUSIONS: It should be borne in mind that seasonal changes and alterations in the amount of light might influence the occurrence of postnatal depression.

When the cradle falls: the treatment of postnatal depression in a psychiatric day hospital compared with routine primary care.

BACKGROUND: Postnatal depression affects one in ten women within 6 months of childbirth. The most effective treatment strategy for postnatal depression is not clear. METHODS: This prospective, naturalistic study of the treatment of postnatal depression compared 30 women treated at a specialised psychiatric day hospital with 30 women treated using routine primary care (RPC). Clinical, marital and social adjustment were assessed on three occasions over 6 months using: the Edinburgh Postnatal Depression Questionnaire (EPDS); the Clinical Interview schedule (CIS); the Anxiety Subscale of the Hospital Anxiety and Depression Scale; the Dyadic Adjustment Scale (DAS); and the Work Leisure and Family Life Questionnaire-Modified (WLFLQ-M). RESULTS: There were no significant differences between the two groups at baseline. However, there were significant differences in outcome at 3 and 6 months follow-up for all outcome measures except the DAS. At 6 month follow-up 21 of the PBDU group were no longer depressed compared with 7 of the RPC group. CONCLUSIONS: A specialised day hospital is a more effective treatment setting for postnatal depression than routine primary care. LIMITATIONS OF THE STUDY: The study is not an RCT, so systematic bias is possible. The sample size is relatively small and the duration of follow-up relatively short.

Psychosocial correlates of prepartum and postpartum depressed mood.

BACKGROUND: The aim of the present study was to delineate the influence of maternal stress, social support and coping styles on depressed mood during pregnancy and the early postpartum period. METHODS: Beginning in the third month of pregnancy, data on numerous variables including daily stress (Hassles), state-anxiety (STAI-state), pregnancy-specific stress (PEQ) and depressed mood (DACL) were collected monthly. In each trimester social support (SSQ), coping strategies (CISS) and pregnancy progress were assessed. Approximately 4-5 weeks following delivery, information on labor, delivery and infant status was collected and the DACL and the Edinburgh Postnatal Depression Scale (EPDS) were administered. The final sample consisted of 80 women. RESULTS: Approximately 16% of the women in this sample experienced depressed mood in the postpartum and 25% of the sample reported depressed mood only during pregnancy. Women depressed only during pregnancy and those depressed in the postpartum reported more emotional coping and higher trait and state anxiety during gestation. More hassles during pregnancy was related to prepartum depressed mood, but not postpartum depressed mood. Consistent with the literature, the best predictor of postpartum depressed mood was depressed mood during pregnancy. LIMITATIONS: The sample size was relatively small and we relied solely on self-reported depressive symptomology. CONCLUSIONS: The findings point to specific psychosocial variables which can be targeted early in pregnancy to reduce the rate of depressed mood in the prepartum and postpartum periods.

About 8- and approximately 84-h rhythms in endotheliocytes as in endothelin-1 and effect of trauma.

Population densities (PD) of capillaries (C) and endotheliocytes (E) were determined in pinnal dermis of C57BL mice before and after trauma. Moving (and overall) least-squares spectra before trauma detected in EPD (versus CPD) pronounced 3.5-day (circasemiseptan) and 8-h oscillations corresponding to components of the endothelin-1 chronome in human blood plasma reported earlier. Circadians were more pronounced in CPD. After trauma, circasemiseptan oscillations appeared also in CPD; their period gradually shortened and in two weeks split into about 2.5- and about 4.5-day oscillations; and circadian components became very pronounced. The pre-traumatic chronome was not restored within three weeks following trauma.

The impact of very premature birth on the psychological health of mothers.

BACKGROUND: The birth of a very premature infant is a critical event in the life of a family and studies have shown that mothers of these infants are at greater risk of psychological distress than mothers of full-term infants. STUDY DESIGN: A total population study of mothers of preterm infants born at less than 32-week gestation at a tertiary referral hospital. SUBJECTS AND METHODS: Sixty-two mothers of very preterm infants (<32 weeks) participated in the present study which examines correlates of maternal depressive symptomatology at 1 month following very premature birth. Information was obtained from structured questionnaires completed by mothers at 1 month after infant admission to neonatal intensive care. RESULTS: Forty percent of the mothers reported significant depressive symptoms on the Edinburgh Postpartum Depression Scale (EPDS). Logistic regression analysis indicated that high maternal stress resulted in an increased likelihood of depressive symptoms (OR 1.15, CI 1.04-1.26, p<0.01). Higher levels of maternal education (p<0.05), and increased perception of support from nursing staff (OR 1.06, CI 0.88-1.00, p<0.05) resulted in decreased likelihood of depressive symptoms. CONCLUSIONS: The birth and subsequent hospitalisation of a very premature infant evokes considerable psychological distress in mothers. These results have implications for policy development in order to enhance family centred care in the neonatal intensive care.

Salt transport and crystallization in porous building materials.

Salt weathering is a major cause of deterioration of porous building materials. To obtain information about the mechanisms underlying these damage processes we have studied the moisture and ion transport. We measured the time evolution of NaCl saturated samples of fired-clay brick during one-sided drying using Nuclear Magnetic Resonance. The moisture content and amount of dissolved Na ions could be measured quantitatively as a function of position. The NaCl concentration profiles obtained from these data reflect the competition between advection to the surface and redistribution by diffusion. By representing the measured moisture and NaCl profiles in an efflorescence pathway diagram (EPD) also the crystallization can be taken into account.

Postnatal depression: a study of mothers in the metropolitan area of Perth, Western Australia.

This paper sets out the extent to which postnatal depression (PND) existed within the Perth metropolitan area of Western Australia in 1993/94. More importantly, the phenomenon of PND, from the mothers' perspective, is described. The paper is based on a two-stage research carried out on PND from 1993 to 1994. In the first stage, the Edinburgh Postnatal Depression Scale (EPDS) was used to screen mothers for PND. A random sample of 399 women showed 72 (18 percent) were found to be suffering from a depressive illness of varying severity. The second stage of the study used a grounded theory approach. Fifteen mothers with PND from the group screened were interviewed in their own homes. A schema, developed from the data, revealed that the main problems of the mothers was vulnerability. Support played a pivotal role in the transition from PND to stable motherhood. There was a long and short circuit followed, according to the availability and non-availability of support.

Estimating psychiatric morbidity by logistic regression: application to post-natal depression in a community sample.

The use of logistic regression to estimate the prevalence of psychiatric morbidity in community samples is illustrated here with data from a study of post-natal depression in 702 primiparous Cambridge mothers. The method is also used to validate the primary screening instrument (in this case the Edinburgh Postnatal Depression Scale--EPDS), and to estimate the effects of cofactors, such as maternal age, previous psychiatric history and social class.
