Interleukin 8 correlates with intestinal involvement in surgically treated infants with necrotizing enterocolitis

PURPOSE

The aim of this study was to test the predictive value of interleukin (IL) 8 in the assessment of intestinal involvement in necrotizing enterocolitis (NEC).

METHODS

Forty infants with surgically treated NEC were classified into 3 groups based on intestinal involvement during laparotomy: focal (n = 11), multifocal (n = 16), and panintestinal (n = 13). Preoperatively obtained serum levels of IL-8, C-reactive protein, white blood cell count, and platelet count were correlated with intestinal involvement using logistic regression models.

RESULTS

Interleukin 8 correlated significantly with intestinal involvement in infants with surgically treated NEC (odds ratio, 1.74; confidence interval, 1.27-2.39; P < .001). An exploratory IL-8 cutoff value of 449 pg/mL provided a specificity of 81.8% and sensitivity of 82.8% to discriminate focal from multifocal and panintestinal disease. An IL-8 cutoff value of 1388 pg/mL provided a specificity of 77.8% and a sensitivity of 76.9% to discriminate panintestinal disease from focal and multifocal disease.

CONCLUSIONS

To our knowledge, this is the first study to demonstrate a significant correlation of IL-8 with intestinal involvement in advanced NEC in a large patient population. Our results indicate that IL-8 may be a promising biomarker for assessing intestinal involvement in infants with advanced NEC.

Perceived parental rearing in subjects with obsessive-compulsive disorder and their siblings

OBJECTIVE

Perceived parenting in patients suffering from obsessive-compulsive disorder (OCD) is examined. We attempted to overcome some methodological limitations of prior studies by taking age of onset, parental OCD and comorbid depression into consideration. In addition, we included data from unaffected siblings to corroborate information on parental rearing.

METHOD

One hundred and twenty-two cases with OCD and 41 of their siblings as well as 59 healthy controls and 45 of their siblings completed the German short-version of the EMBU (FEE).

RESULTS

Obsessive-compulsive disorder cases reported less parental warmth and more parental rejection and control. Further analyses indicated that parenting is also associated with OCD in cases with late onset and cases without parents affected by OCD. OCD cases with comorbid depression described their parents particularly negatively. Data from siblings indicated good validity of perceived parenting in OCD.

CONCLUSION

This study provides further evidence for dysfunctional child rearing being relevant to the development of OCD and depression.

Prevalence, onset and comorbidity of postpartum anxiety and depressive disorders

OBJECTIVE

The study presents data on the 3-month prevalences of postpartum anxiety disorders (PAD) and postpartum depressive disorders (PDD) and their comorbidity in a German community sample. Associations with sociodemographic variables and previous history of psychopathology were analysed.

METHOD

Data were gathered in a longitudinal study over the first 3 months postpartum. In a two-stage screening procedure, a population-based representative sample of 1024 postpartum women was assessed for symptoms of anxiety and depression using DSM-IV-based screening instruments.

RESULTS

The estimated rates of DSM-IV disorders were 11.1% for PAD and 6.1% for PDD. Comorbidity was found in 2.1%. The rate for PAD with postpartum onset was 2.2% and for PDD 4.6%. Young mothers and mothers with a low education level had a heightened risk of developing depression following delivery.

CONCLUSION

Because of the clinical relevance of PAD, controlled studies and specialized programmes for prevention and treatment are urgently required.

FENOTIPIA E CONCENTRAÇÃO INIBITÓRIA MÍNIMA (CIM) EM LINHAGENS DE ESCHERICHIA COLI ISOLADAS DE LEITÕES COM DIARRÉIA NAS FASES DE MATERNIDADE, CRECHE, CRESCIMENTO E TERMINAÇÃO

RESUMO Escherichia coli é reconhecida como causa freqüente de diarréia em suínos em todo o mundo. O objetivo do presente estudo foi caracterizar fenotipicamente os tipos fimbriais de 349 linhagens de E. coli isoladas de suínos com diarréia, em diferentes faixas etárias, utilizando os testes de microhemaglutinação e soroaglutinação, bem como determinar o perfil de suscetibilidade frente aos principais antimicrobianos utilizados em granjas de suínos. Do total de 159 linhagens de E. coli que não aglutinaram eritrócitos no teste de hemaglutinação manose-resistente (HAMR), 57 (35%) foram positivas para a expressão do antígeno fimbrial F6 no teste de soroaglutinação rápida em placa. Considerando a faixa etária e o fenótipo fimbrial, os sorotipos de E. coli, potencialmente patogênicos mais prevalentes até a terceira semana de idade, foram F5 (K99), F6 (987P), F42 e F41 em, respectivamente, 29%, 23%, 11% e 10% das linhagens. Em leitões com mais de 25 dias, predominaram fimbrias F4 (K88) em 44,6% (58) das linhagens. Os animais foram suscetíveis às cepas contendo F4, durante todas as faixas etárias, mas com maior predominância em idades mais avançadas, acima de 76 dias. Os maiores índices de resistência das linhagens foram observados para oxitetraciclina (84,0%), gentamicina (76,0 %) e amoxicilina (72,0%). Os menores valores de Concentração Inibitória Mínima (CIM) 50 e 90 foram observados para o ceftiofur.

Complications during pregnancy, peri- and postnatal period in a sample of women with a history of child abuse

BACKGROUND

As a proposed risk factor for infant and child development, maternal history of abuse has been a frequent target of investigation. However, there have been no controlled studies about the impact of maternal history of abuse on the medical course of pregnancy, the peri- and postnatal period.

METHOD

All women with a newborn child were contacted by mail and presented with the Childhood Trauma Questionnaire (CTQ). The index group (n = 58) was formed by women who scored above the cutoff for moderate or severe abuse and compared to a control group (n = 60) with regard to pre,- peri-, and postnatal complications as documented in the patient charts.

RESULTS

The results show that women with a history of abuse have significantly more prenatal medical complications and infant medical complications in the post- but not perinatal period.

CONCLUSIONS

Maternal history of abuse significantly impacts the medical course of delivery and the puerperium. Given the prevalence of abusive experiences, this finding is highly relevant from a preventive point of view.

Childhood behavioral inhibition and maternal symptoms of depression

BACKGROUND

The significance of behavioral inhibition in the second year of life for the development of social phobia in later childhood was the incentive to explore whether maternal postnatal psychopathology is a predictor for behavioral inhibition in the offspring.

METHOD

101 mother-infant pairs were recruited from local obstetric units and examined for maternal psychopathology by the Symptom Checklist and the Edinburgh Postnatal Depression Scale several times during the first postnatal year. Child behavioral inhibition was assessed at 14 months in a laboratory procedure.

RESULTS

Postpartum depression at 4 months measured by the Edinburgh Postnatal Depression Scale was found to be strongly associated with toddlers' fear score/behavioral inhibition at 14 months. Maternal depressive symptoms assessed by the revised 90-item Symptom Checklist at 6 weeks , 4 and 14 months were found to be related to child inhibition as well.

CONCLUSIONS

Even maternal depression not reaching the level of clinical diagnosis and treatment has an impact on child behavioral development. These data should give rise to further studies on the origins of this relationship, which might be primarily genetic or interactional.

Impulsiveness in obsessive-compulsive disorder: results from a family study

OBJECTIVE

Although obsessive-compulsive disorder (OCD) is usually conceptualized as an anxiety disorder some studies suggested it to be a deficit of impulse control. The purpose of this study was to assess impulsiveness in OCD families and compare it to control families.

METHOD

Seventy cases and their 139 relatives were compared with 70 controls and their 134 relatives from a German family study on OCD (German Epidemiologic Network for OCD Studies). All subjects were interviewed and diagnosed according DSM-IV criteria and were administered the Barratt Impulsiveness Scale (BIS) and PADUA-Inventory to assess obsessive-compulsive symptoms.

RESULTS

OCD subjects had significantly higher scores of cognitive impulsiveness. However, first-degree relatives of OCD cases and of controls had comparable BIS-11 scores. Significant associations of aggressive obsessions and checking with cognitive impulsiveness were found.

CONCLUSION

OCD is a severe mental disorder that is characterized by a lack of cognitive inhibition. However, impulsiveness does not represent a familial trait in families of OCD subjects.

Maternal depressive symptoms in the postnatal period are associated with long-term impairment of mother-child bonding

BACKGROUND

Postnatal Depression has demonstrated long-term consequences on child cognitive and emotional development, however, the link between maternal and child pathology has not been clearly identified.

OBJECTIVE

This study examined whether maternal bonding to the infant and young child is impaired by maternal depressive symptoms.

METHODS

101 mothers of newborn infants were recruited from local obstetric units and examined for psychopathology using Symptom Checklist, the Edinburgh Postnatal Depression Scale (EPDS) and the Postpartum Bonding Questionnaire at two weeks, six weeks, four months and fourteen months postpartum.

RESULTS

Maternal depressive symptoms at 2 weeks, 6 weeks and four months postnatally but not at fourteen months of infant's age were found to be strongly associated with lower quality of maternal bonding to the infant and child from two weeks until fourteen months of postnatal age. Even mild and unrecognized maternal depressive symptoms had a significant impact on maternal bonding, if they occurred during the first four months of life.

CONCLUSIONS

This gives reason for increased concern for mother-infant dyads in the first few months after birth that could be regarded as a highly sensitive period for the development of the mother-child relationship. The findings warrant further studies and inspire the development of preventive programs focussing on infant and early childhood mental health by emphasizing protection and support during the first critical months.

The German version of the Postpartum Bonding Instrument: psychometric properties and association with postpartum depression

BACKGROUND

To date there has been no study investigating mother-infant bonding impairment and its link to pospartum depressive symptoms in a representative German population sample. The present study therefore aimed to carry out initial analyses of the psychometric properties of the German version of the Postpartum Bonding Questionnaire (PBQ).

METHODS

Eight hundred and sixty two mothers provided the data for a principal component analysis of the original 25 item PBQ. This analysis was used to assess the validity of the four scale structure of the questionnaire. Correlations between postpartum depression, sociodemographic variables and bonding impairment were additionally calculated.

FINDINGS

On the basis of our data, the original 4 factor structure of the PBQ scale was not confirmed. Nine items did not meaningfully load onto the single factor accounting for the most variance. Mother-infant bonding impairment and postpartum depression were shown to be significantly positively correlated. According to the factor solution of Brockington we found a 7.1% rate of mothers with bonding impairment two weeks postpartum (with 95% confidence ranging from 5.5 to 9%).

INTERPRETATION

An abridged 16 item German version of the PBQ can be implemented as a reliable screening instrument for bonding impairment.

Mutter-Kind-Behandlung bei postpartalen Störungen im internationalen Vergleich

Postnatal depression is among the most frequent mental disorders in young women (incidence 10-15 %). Besides depressive illness, however anxiety disorder, stress disorder and psychosis play an important role as well. These disorders have not only negative impact on women's mental health, but may also adversely affect the child's development as well as the mother-child relationship. Inpatient mother-child care as established e. g. at the Heidelberg University Hospital offers adequate treatment without the need for the mother to separate from her child. In a retrospective study a profile of the women treated at the Psychiatric Department of the University Hospital Heidelberg was developed which reflects the psychological and social stress in their life situations. In order to gain an overview on the specific treatment options the data were then compared with those of other national and international centres. Analysis of demand shows that this mother-child psychiatric care is well accepted by the population and that there is a considerable need for adequate in- and outpatient care of postnatal mental disorders.
