RESUMO

OBJECTIVES: To describe the incidence and outcomes of pulmonary oedema in women with severe maternal outcome during childbirth and identify possible modifiable factors through audit. METHODS: All women with severe maternal outcome (maternal deaths or near misses) who were referred to Tygerberg referral hospital from health facilities in Metro East district, South Africa, during 2014-2015 were included. Women with severe maternal outcome and pulmonary oedema during pregnancy or childbirth were evaluated using three types of critical incident audit: criterion-based case review by one consultant gynaecologist, monodisciplinary critical incident audit by a team of gynaecologists, multidisciplinary audit with expert review from anaesthesiologists and cardiologists. RESULTS: Of 32,161 pregnant women who gave birth in the study period, 399 (1.2%) women had severe maternal outcome and 72/399 (18.1%) had pulmonary oedema with a case fatality rate of 5.6% (4/72). Critical incident audit demonstrated that pre-eclampsia/HELLP-syndrome and chronic hypertension were the main conditions underlying pulmonary oedema (44/72, 61.1%). Administration of volumes of intravenous fluids in already sick women, undiagnosed underlying cardiac illness, administration of magnesium sulphate as part of pre-eclampsia management and oxytocin for augmentation of labour were identified as possible contributors to the pathophysiology of pulmonary oedema. Women-related factors (improved antenatal care attendance) and health care-related factors (earlier diagnosis and management) would potentially have improved maternal outcome. CONCLUSIONS: Although pulmonary oedema in pregnancy is rare, among women with severe maternal outcome a considerable proportion had pulmonary oedema (18.1%). Audit identified options for prevention of pulmonary oedema and improved outcome. These included early detection and management of preeclampsia with close monitoring of fluid intake and cardiac evaluation in case of suspected pulmonary oedema. Therefore, a multidisciplinary clinical approach is recommended.

RESUMO

BACKGROUND: Attachment parameters affect the development of self-concept and relationship patterns. However, studies on the impact of attachment parameters on symptoms of the offspring in childhood are still lacking. We therefore investigated the influence of attachment parameters of the grandparents on those of the parents treated in a psychiatric hospital, and finally on the symptoms of their (grand)children. Furthermore, the impact of attachment factors on parenting style and on resilience of parents and children has been examined. SUBJECTS AND METHODS: A sample of n=50 mother-child-dyads in an inpatient setting was examined using the questionnaires FEB (Questionnaire on the Parental Attachment; adult and child perspective), RQ2 (Relationship Questionnaire), EFB-K (Educational Questionnaire, short form), RS13 (Resilience Scale; adult and child perspective), and CBCL (Child Behavior Checklist). Regression analyses and correlation analyses were carried out. RESULTS: On grandparents' level, attachment patterns predicted parents' attachment patterns (p=0.012): Grandfather's care (control) behavior correlated with more (less) mother's care for their own children (0.002 (0.005)). Control behavior of the grandfather was negatively correlated with the resilience of their daughters (p=0.033). On parents' level, a secure attachment style predicted a less overreacting parenting style (p=0.004), whereas an anxious-avoiding (p=0.035) or clinging attachment style (p=0.044) predicted an increased overreacting parenting style. On child's level, mental (esp. attentional (p=0.013) and externalizing (p=0.032)) symptoms correlated negatively with the level of care reported by the mother. CONCLUSION: Functional attachment behavior at the grandparents' level correlated significantly with functional attachment behavior at the parental level, which in turn correlated with reduced mental symptoms at the child's level. The parenting style seems to play a mediator role for the development of attachment between mother and child, with resilience mediating between attachment and the onset of mental disorders. The results point to the crucial role of attachment parameters for mental development with corresponding implications for psychotherapy.

RESUMO

OBJECTIVE: To describe the incidence and main causes of maternal near-miss events in middle-income countries using the World Health Organization's (WHO) maternal near-miss tool and to evaluate its applicability in these settings. METHODS: We did a systematic review of studies on maternal near misses in middle-income countries published over 2009-2020. We extracted data on number of live births, number of maternal near misses, major causes of maternal near miss and most frequent organ dysfunction. We extracted, or calculated, the maternal near-miss ratio, maternal mortality ratio and mortality index. We also noted descriptions of researchers' experiences and modifications of the WHO tool for local use. FINDINGS: We included 69 studies from 26 countries (12 lower-middle- and 14 upper-middle-income countries). Studies reported a total of 50 552 maternal near misses out of 10 450 482 live births. Median number of cases of maternal near miss per 1000 live births was 15.9 (interquartile range, IQR: 8.9-34.7) in lower-middle- and 7.8 (IQR: 5.0-9.6) in upper-middle-income countries, with considerable variation between and within countries. The most frequent causes of near miss were obstetric haemorrhage in 19/40 studies in lower-middle-income countries and hypertensive disorders in 15/29 studies in upper-middle-income countries. Around half the studies recommended adaptations to the laboratory and management criteria to avoid underestimation of cases of near miss, as well as clearer guidance to avoid different interpretations of the tool. CONCLUSION: In several countries, adaptations of the WHO near-miss tool to the local context were suggested, possibly hampering international comparisons, but facilitating locally relevant audits to learn lessons.

RESUMO

BACKGROUND: Major obstetric haemorrhage is a leading cause of maternal mortality and accounts for one-third of maternal deaths in of Africa. This study aimed to assess the population-based incidence, causes, management and outcomes of major obstetric haemorrhage and risk factors associated with poor maternal outcome. METHODS: Women with major obstetric haemorrhage who met the WHO maternal near-miss criteria or died in the Metro East region, Cape Town, South Africa, were evaluated from November 2014-November 2015. Major obstetric haemorrhage was defined as haemorrhage in pregnancies of at least 20 weeks' gestation or occurring up to 42 days after birth, and leading to hysterectomy, hypovolaemic shock or blood transfusion of ≥5 units of Packed Red Blood Cells. A logistic regression model was used to analyse associations with poor outcome, defined as major obstetric haemorrhage leading to massive transfusion of ≥8 units of packed red blood cells, hysterectomy or death. RESULTS: The incidence of major obstetric haemorrhage was 3/1000 births, and the incidence of massive transfusion was 4/10.000 births in the Metro East region (32.862 births occurred during the studied time period). Leading causes of haemorrhage were placental abruption 45/119 (37.8%), complications of caesarean section 29/119 (24.4%) and uterine atony 13/119 (10.9%). Therapeutic oxytocin was administered in 98/119 (82.4%) women and hysterectomy performed in 33/119 (27.7%). The median numbers of packed red blood cells and units of Fresh Frozen Plasma transfused were 6 (interquartile range 4-7) and 3 (interquartile range 2-4), ratio 1.7:1. Caesarean section was independently associated with poor maternal outcome: adjusted OR 4.01 [95% CI 1.58, 10.14]. CONCLUSIONS: Assessment of major obstetric haemorrhage using the Maternal Near Miss approach revealed that placental abruption and complications of caesarean section were the major causes of major obstetric haemorrhage. Caesarean section was associated with poor outcome.

RESUMO

BACKGROUND: To examine psychopathology present under prolonged antipsychotic treatment in schizophrenia and to analyse their relationship to both the duration of the prodromal stage (DPS; time between onset of first unspecific psychological symptoms and first schizophrenic symptoms) and the duration of untreated psychosis (DUP; time between the onset of psychosis and the initiation of antipsychotic treatment). METHODS: The psychopathology of 93 patients was assessed cross-sectionally using the Scales for the Assessment of Negative and Positive Symptoms and the Brief Psychiatric Rating Scale. DPS and DUP were assessed by means of the patient records and the Interview for the Retrospective Assessment of the Onset and Course of Schizophrenia and Other Psychoses. A path analysis using maximum likelihood estimation was conducted with the program Analysis of Moment Structures for Windows. RESULTS: The resulting path model indicated that DPS was predictive for a more severe negative symptomatology in schizophrenia, whereas DUP was associated with a more severe positive symptomatology in the long-term. Furthermore, DUP showed an inverse correlation with the age of the patients at the onset of both first unspecific psychological symptoms and first schizophrenic symptoms. CONCLUSION: A long prodromal stage suggests an increased risk of a long-term progression with negative symptoms in schizophrenia, whereas a delayed start of antipsychotic treatment could lead to an increased manifestation and severity of positive symptoms in the long term. These results underline the need to shorten the duration of the prodrome by an early detection and adequate intervention in patients with increased risk to develop psychosis.

RESUMO

BACKGROUND: Attachment parameters have an effect on later relationship patterns and the development of parameters of self-concept and personality. In the current study the role of attachment parameters on personality dimensions was investigated, especially with respect to personality disorders. SUBJECTS AND METHODS: 134 psychiatric inpatients were examined on attachment and personality parameters using the schedule FEB as a questionnaire on the parental attachment and the SKI as a self-concept inventory. RESULTS: Regression and correlation analyses suggest positive influences of parental care and negative influences of parental overprotection on the development of ego-strength in adulthood. Patients with personality disorders reported to have experienced less maternal care during their childhood and showed a trend towards a reduced ego-strength in adulthood compared to patients with others mental disorders. CONCLUSIONS: Relationships of attachment parameters in childhood with personality dimension are explorable. This approach seems meaningful for a better understanding of the development of personality disorders. Clinicians should be familiar with attachment patterns when treating people with mental disorders in order to adequately include appropriate personality dimensions in the therapy.

RESUMO

BACKGROUND: Value-based health care aims to optimize the balance of patient outcomes and health care costs. To improve value in perinatal care using this strategy, standard outcomes must first be defined. The objective of this work was to define a minimum, internationally appropriate set of outcome measures for evaluating and improving perinatal care with a focus on outcomes that matter to women and their families. METHODS: An interdisciplinary and international Working Group was assembled. Existing literature and current measurement initiatives were reviewed. Serial guided discussions and validation surveys provided consumer input. A series of nine teleconferences, incorporating a modified Delphi process, were held to reach consensus on the proposed Standard Set. RESULTS: The Working Group selected 24 outcome measures to evaluate care during pregnancy and up to 6 months postpartum. These include clinical outcomes such as maternal and neonatal mortality and morbidity, stillbirth, preterm birth, birth injury and patient-reported outcome measures (PROMs) that assess health-related quality of life (HRQoL), mental health, mother-infant bonding, confidence and success with breastfeeding, incontinence, and satisfaction with care and birth experience. To support analysis of these outcome measures, pertinent baseline characteristics and risk factor metrics were also defined. CONCLUSIONS: We propose a set of outcome measures for evaluating the care that women and infants receive during pregnancy and the postpartum period. While validation and refinement via pilot implementation projects are needed, we view this as an important initial step towards value-based improvements in care.

RESUMO

BACKGROUND: Pain is a common symptom in patients with depressive disorders, which, if present, worsens the prognosis. However, there is little empirical knowledge of the therapeutic effects of antidepressants on painful physical symptoms of patients with depressive disorders. Furthermore, tricyclic/tetracyclic antidepressants (TCAs) have not yet been included in existing meta-analyses. METHODS: A broad, systematic search of PubMed literature on antidepressant drug treatment of patients with depressive disorders with comorbid pain symptoms was carried out. A random-effects meta-analysis has been performed among 3 different groups of drugs for the 2 end points: pain and depression. RESULTS: Fourteen placebo-controlled studies with selective serotonin-noradrenaline reuptake inhibitors (SSNRIs) could be included, with 3 of them also investigating selective serotonin reuptake inhibitors (SSRIs). Three further placebo-controlled SSRI studies were identified, but only 2 placebo-controlled TCA studies.Both SSNRIs and SSRIs, but not TCAs, were significantly superior to placebo as regards their analgesic effects. However, all effects were small. For SSNRIs, there was a strong positive correlation between their effectiveness for pain relief and their positive effect on the mood of the patients. DISCUSSION: The analgesic effects of SSNRIs and SSRIs in patients with primary depressive disorders can be interpreted as largely equivalent. Because of a lack of placebo-controlled TCA studies, the results for TCAs would be comparable only to those of SSRIs and SSNRIs, if non-placebo-controlled TCA studies were included. The positive correlation found indicates a close relationship of pain relief and antidepressant treatment effects. These results refer merely to patients with primary depressive disorders, not to patients with primary pain disorders. Further studies comparing the effects of different types of antidepressant drugs on pain in depressive patients are warranted.

RESUMO

OBJECTIVE: To demonstrate that successful health systems strengthening (HSS) projects have addressed disparities and inequities in maternal and perinatal care in low-income countries. METHODS: A comprehensive literature review covered the period between 1980 and 2022, focusing on successful HSS interventions within health systems' seven core components that improved maternal and perinatal care. RESULTS: The findings highlight the importance of integrating quality interventions into robust health systems, as this has been shown to reduce maternal and newborn mortality. However, several challenges, including service delivery gaps, poor data use, and funding deficits, continue to hinder the delivery of quality care. To improve maternal and newborn health outcomes, a comprehensive HSS strategy is essential, which should include infrastructure enhancement, workforce skill development, access to essential medicines, and active community engagement. CONCLUSION: Effective health systems, leadership, and community engagement are crucial for a comprehensive HSS approach to catalyze progress toward universal health coverage and global improvements in maternal and newborn health.

RESUMO

OBJECTIVE: A high degree of satisfaction is probably one of the most important aims for each patient during medical treatment. However, database on the influencing variables in a general psychiatric inpatient sample is still small. Therefore, the objective of this study is to identify clinical variables related to patients' treatment satisfaction. METHODS: In 113 patients (59 females; mean age, 48.3 ± 16.6 years; mean treatment duration, 1.4 ± 1.2 months) admitted to a psychiatric hospital, data were assessed on treatment satisfaction using the ZUF-8 questionnaire ("Fragebogen zur Patientenzufriedenheit"; questionnaire of patient satisfaction) at discharge and on general treatment variables as well as the psychosocial functioning using the "Basisdokumentation" (basic documentation) questionnaire including Clinical Global Impression scale (CGI) and Global Assessment of Functioning scale (GAF) at admission and discharge. Student t tests, univariate variance analyses, and Pearson correlations were performed. RESULTS: ZUF-8 sum score correlated significantly negatively with CGI score at discharge (part 1: P = .036), positively with GAF at discharge (P = .011), and as a trend with the reduction of CGI during the treatment (CGI change; P = .050). Patients with pharmacologic disturbances (P = .003) and with a schizophrenia spectrum disorder or a personality disorder were less content (trend; P = .071). Satisfaction did not differ in dependency of the variables age, sex, native language, number of inpatient treatments, therapeutic setting of the ward, duration of disorder or treatment, level of school education, bodily impairment, number of somatic diagnoses, psychopharmacologic treatment (vs none), antidepressants, body weight, or body weight change. CONCLUSION: The results of the study suggest that patient satisfaction is dependent on symptom severity and global functioning at discharge, on pharmacologic disturbances during treatment, and on the diagnostic group. Therefore, symptom relief and reduction of adverse side effects as far as possible should be the primary aim of an inpatient treatment.

RESUMO

Our knowledge of pharmacogenetic variability in diverse populations is scarce, especially in sub-Saharan Africa. To bridge this gap in knowledge, we characterised population frequencies of clinically relevant pharmacogenetic traits in two distinct South African population groups. We genotyped 211 tagging single nucleotide polymorphisms (tagSNPs) in 12 genes that influence antiretroviral drug disposition, in 176 South African individuals belonging to two distinct population groups residing in the Western Cape: the Xhosa (n = 109) and Cape Mixed Ancestry (CMA) (n = 67) groups. The minor allele frequencies (MAFs) of eight tagSNPs in six genes (those encoding the ATP binding cassette sub-family B, member 1 [ABCB1], four members of the cytochrome P450 family [CYP2A7P1, CYP2C18, CYP3A4, CYP3A5] and UDP-glucuronosyltransferase 1 [UGT1A1]) were significantly different between the Xhosa and CMA populations (Bonferroni p < 0.05). Twenty-seven haplotypes were inferred in four genes (CYP2C18, CYP3A4, the gene encoding solute carrier family 22 member 6 [SLC22A6] and UGT1A1) between the two South African populations. Characterising the Xhosa and CMA population frequencies of variant alleles important for drug transport and metabolism can help to establish the clinical relevance of pharmacogenetic testing in these populations.

RESUMO

OBJECTIVE: Administration of atypical antipsychotics often induces significant weight gain and metabolic changes. Little is known about subjective weight-related parameters in adolescent patients. Therefore, this cross-sectional, explorative study aimed to assess these parameters and their relationship with biological weight-related parameters. METHOD: 74 patients (mean age: 19.9 [SD ± 2.3] years; 66.2% male) with schizophrenia under clozapine or olanzapine treatment were examined. Subjective well-being, eating behavior, body perception and social functioning were assessed, using the Three-Factor-Eating-Questionnaire, FKB-20 Body Perception Questionnaire, Subjective Well-being under Neuroleptics, Short Form and Global Assessment of Functioning. Patients' biological weight-related parameters were measured as well. Gender differences as well as associations between subjective and biological weight-related parameters were evaluated. RESULTS: Female patients reported significantly worse negative body appraisal and physical functioning than males. An elevated BMI was associated with impaired physical functioning in females and with negative body appraisal and hunger in males. CONCLUSIONS: In our sample of young patients with schizophrenia unter treatment with atypical antipsychotics, an elevated BMI was associated with impaired physical functioning and negative body appraisal, respectively. Bearing in mind the high risk of obesity in this population, the mentioned impairments should be accounted for, especially in terms of compliance and quality of life.

RESUMO

INTRODUCTION: Autopsy is regarded as the "gold standard" to determine probable causes of stillbirths. However, autopsy is expensive and not readily available in low- and middle-income countries. Therefore, we assessed how the clinical cause of death is modified by adding placental histology and autopsy findings. METHOD: Data from the Safe Passage Study was used where 7060 pregnant women were followed prospectively. Following a stillbirth, each case was discussed and classified at weekly perinatal mortality meetings. This classification was later adapted to the WHO ICD PM system. Clinical information was presented first, and a possible cause of death decided upon and noted. The placental histology was then presented and, again, a possible cause of death, using the placental and clinical information, was decided upon and noted, followed by autopsy information. Diagnoses were then compared to determine how often the additional information changed the initial clinical findings. RESULTS: Clinical information, placental histology, and autopsy results were available in 47 stillbirths. There were major amendments from the clinical only diagnoses when placental histology was added. Forty cases were classified as due to M1: complications of placenta, cord, and membranes, when placental histology was added compared to 7 cases with clinical classification only, and M5: No maternal condition identified decreased from 30 cases to 3 cases. Autopsy findings confirmed the clinical and placental histology findings. DISCUSSION: Clinical information together with examination of the placenta revealed sufficient information to diagnose the most probable cause of death in 40 of 47 cases of stillbirth (85%).

RESUMO

PURPOSE: The Western Cape Pregnancy Exposure Registry (PER) was established at two public sector healthcare sentinel sites in the Western Cape province, South Africa, to provide ongoing surveillance of drug exposures in pregnancy and associations with pregnancy outcomes. PARTICIPANTS: Established in 2016, all women attending their first antenatal visit at primary care obstetric facilities were enrolled and followed to pregnancy outcome regardless of the site (ie, primary, secondary, tertiary facility). Routine operational obstetric and medical data are digitised from the clinical stationery at the healthcare facilities. Data collection has been integrated into existing services and information platforms and supports routine operations. The PER is situated within the Provincial Health Data Centre, an information exchange that harmonises and consolidates all health-related electronic data in the province. Data are contributed via linkage across a unique identifier. This relationship limits the missing data in the PER, allows validation and avoids misclassification in the population-level data set. FINDINGS TO DATE: Approximately 5000 and 3500 pregnant women enter the data set annually at the urban and rural sites, respectively. As of August 2021, >30 000 pregnancies have been recorded and outcomes have been determined for 93%. Analysis of key obstetric and neonatal health indicators derived from the PER are consistent with the aggregate data in the District Health Information System. FUTURE PLANS: This represents significant infrastructure, able to address clinical and epidemiological concerns in a low/middle-income setting.

RESUMO

Oxidative DNA damage as one sign of reactive oxygen species induced oxidative stress is an important factor in the pathogenesis of various psychiatric disorders. Altered levels of DNA base damage products as well as the expression of the main repair enzyme 8-hydroxyguanine glycosylase 1 have been described. The aim of the present study was to examine the effects of drugs (amphetamine, methylphenidate and atomoxetine) used in the treatment of attention deficit-hyperactivity disorder on the expression of this enzyme via reverse transcriptase-polymerase chain reaction in human neuroblastoma SH-SY5Y and human monocytic U-937 cells at concentrations of 50, 500 and 5,000 ng/ml. We observed decreased expression of this enzyme for all applied substances. In U-937 cells, the significance level was reached after treatment with 5,000 ng/ml amphetamine as well as after treatment with 50, 500 and 5,000 ng/ml atomoxetine. Incubation of SH-SY5Y cells with 50 and 5,000 ng/ml amphetamine and 5,000 ng/ml methylphenidate led to significant decreases of 8-hydroxyguanine glycosylase 1. As a positive correlation between the expression of 8-hydroxyguanine glycosylase 1 and the level of oxidative DNA damage products has been described, we accordingly consider these substances (amphetamine, methylphenidate and atomoxetine) to possibly play a protective role in this process.

RESUMO

South Africa, like many other Southern African countries, has one of the highest HIV infection rates in the world and many individuals consequently receive antiretroviral therapy (ART). However, knowledge regarding (i) the prevalence of functional single nucleotide polymorphisms (SNPs) in pharmacologically relevant genes, and (ii) variance in pharmacotherapy both within and between different populations and ethnic groups is limited. The aim of this study was to determine whether selected polymorphisms in cytochrome P450 (CYP) genes (CYP2B6 and CYP3A4) and the multidrug-resistance 1 (ABCB1) gene underlie altered antiretroviral (ARV) drug response in two South African populations. DNA samples from 182 HIV-positive individuals of Mixed-Ancestry and Xhosa ethnicity on ART were genotyped for the A-392G SNP in CYP3A4, the G516T and A785G SNPs in CYP2B6, and the T-129C, C1236T, G2677T/A and C3435T SNPs in ABCB1. Univariate two-way analysis of variance (ANOVA) testing revealed no apparent effect of ethnicity on immune recovery (in terms of CD4-cell count) in response to ART. Univariate one-way ANOVA testing revealed a discernible effect of genotype on immune recovery in the cases of the T-129C (P=0.03) and G2677A (P<0.01) polymorphisms in the ABCB1 gene. This study serves as a basis for better understanding and possible prediction of pharmacogenetic risk profiles and drug response in individuals and ethnic groups in South Africa.

RESUMO

OBJECTIVE: To explore the impact of premorbid and baseline body mass indices (BMIs) as well as BMI of patient's parents and associated variables on the prediction of antipsychotic-induced body weight gain. METHODS: Retrospective/cross-sectional data of 65 patients receiving clozapine, olanzapine and/or risperidone were assessed according to a systematic categorization of the long-term (7.3+/-9.2 years) weight course and evaluated using descriptive, explorative correlation and regression analyses. RESULTS: Increased values of parents' BMI (p=0.041) and patients' BMI at premorbid stage (p=0.039) and prior to first antipsychotic treatment (p=0.032) as well as female gender (p=0.012), younger age (p=0.005) and non-smoking (p=0.047) have the most predictive value on body weight gain under antipsychotic treatment including pre-treatment with typical antipsychotics. Weight gain under atypical antipsychotics (pre-treatment excluded) is predicted by an increased premorbid BMI (p=0.019). Conversely, a low BMI prior to first antipsychotic treatment predicts a higher acceleration of BMI change (p=0.008) in vulnerable individuals, but not total BMI change itself. Furthermore, a diagnosis of a schizophrenia spectrum disorder showed a trend towards the prediction of an increased atypical DeltaBMI (p=0.067), possibly due to a longer treatment duration with atypical antipsychotics (p<0.001). DISCUSSION: The study indicates increased parents' BMI and patients' premorbid BMI, female gender, younger age and - as a trend - the diagnosis of a schizophrenia spectrum disorder to be predictors for antipsychotic-induced body weight gain involving atypical antipsychotics. Data contribute to the assumption of a strong impact of predispositional factors on weight gain, besides treatment-related factors.

RESUMO

OBJECTIVE: To determine incidence, risk indicators, and outcomes of emergency peripartum hysterectomy (EPH) in Metro East, Cape Town, South Africa. METHODS: A population-based district-wide prospective descriptive study of EPH in public hospitals from November 2014 to November 2015. Women were enrolled by using the WHO maternal near miss tool and followed until discharge. EPH was defined as hemorrhage or infection leading to hysterectomy during pregnancy or within 42 days of delivery. RESULTS: Fifty-nine women experienced EPH with an overall incidence of 14.3 per 10 000 women: 32 procedures were for postpartum hemorrhage, 27 for puerperal sepsis. Two women died: one from sepsis; one from hemorrhage. Overall, 51 (86%) women delivered by cesarean, and 23/51 (45%) by repeat cesarean. As compared with hemorrhage, EPH for sepsis involved older women (mean age, 31.5 vs 24.4 years) and those with higher gravidity (median, 3 vs 1), and was associated with longer hospital admission (median, 11.5 vs 4 days), with occurrence later postpartum (median, 8 vs 0 days), and more frequently with complications. CONCLUSIONS: The incidence of EPH for sepsis was higher than previously reported. Repeat cesarean was strongly associated with EPH. Clinical characteristics of sepsis-related EPH compared unfavorably with those of hemorrhage-related EPH.

RESUMO

OBJECTIVE: Antidepressants (AD) (desipramine, imipramine, maprotiline, mirtazapine) and corticosteroid (CS) were examined for their effects on gene expression in human monocytic U-937 blood cells. Endocrine and signaling-related response patterns were determined by expression analysis of different factors, comprising endocrine (glucocorticoid receptor [GR], GR-alpha/beta/gamma; mineralocorticoid receptor [MR]) and signaling-related pathways (p105, STAT3, c-jun, c-fos, JNK1, GAPDH, TNF-alpha). METHODS: A semiquantitative RT-PCR for factor responses after 24 h of treatment was conducted and exploratory multivariate statistical procedures were applied for further analysis. RESULTS: Compared to controls, significant reduction of mRNA levels of GR-beta under imipramine and of c-jun under desipramine treatment were found. CS treatment significantly reduced mRNA levels of GR-alpha/beta, TNF-alpha, p105 and c-jun compared to controls. Compared to CS treatment, significantly increased mRNA levels were found for JNK1 under imipramine treatment and for GR-alpha after treatment with all AD examined. DISCUSSION: The multivariate approach meets the requirements of the complex situation of metabolic reactions induced by AD or CS treatment. Our data show that AD affect both, endocrine and signaling-related factors in human monocytic U-937 blood cells, although clearly not in a uniform manner. Hereby, GR is obviously playing a comparably central role. Overall, AD treatment might indeed normalize deviations of cellular endocrine and signaling-related pathways in major depressive disorder via the mechanisms examined.
