Prospective Associations of Lifetime Post-traumatic Stress Disorder and Birth-Related Traumatization With Maternal and Infant Outcomes

Objective: Many women experience traumatic events already prior to or during pregnancy, and delivery of a child may also be perceived as a traumatic event, especially in women with prior post-traumatic stress disorder (PTSD). Birth-related PTSD might be unique in several ways, and it seems important to distinguish between lifetime PTSD and birth-related traumatization in order to examine specific consequences for mother and child. This post-hoc analysis aims to prospectively examine the relation of both, lifetime PTSD (with/without interpersonal trauma) and birth-related traumatization (with/without postpartum depression) with specific maternal and infant outcomes. Methods: In the prospective-longitudinal Maternal in Relation to Infants' Development (MARI) study, N = 306 women were repeatedly assessed across the peripartum period. Maternal lifetime PTSD and birth-related traumatization were assessed with the Composite International Diagnostic Interview for women. Maternal health during the peripartum period (incl. birth experience, breastfeeding, anxiety, and depression) and infant outcomes (e.g., gestational age, birth weight, neuropsychological development, and regulatory disorders) were assessed via standardized diagnostic interviews, questionnaires, medical records, and standardized observations. Results: A history of lifetime PTSD prior to or during pregnancy was reported by 25 women who indicated a less favorable psycho-social situation (lower educational level, less social support, a higher rate of nicotine consumption during pregnancy). Lifetime PTSD was associated with pregnancy-related anxieties, traumatic birth experience, and anxiety and depressive disorders after delivery (and in case of interpersonal trauma additionally associated with infant feeding disorder). Compared to the reference group, women with birth-related traumatization (N = 35) indicated numerous adverse maternal and infant outcomes (e.g., child-related fears, sexual problems, impaired bonding). Birth-related traumatization and postpartum depression was additionally associated with infant feeding and sleeping problems. Conclusion: Findings suggest that both lifetime PTSD and birth-related traumatization are important for maternal and infant health outcomes across the peripartum period. Larger prospective studies are warranted. Implications: Women with lifetime PTSD and/or birth related traumatization should be closely monitored and supported. They may benefit from early targeted interventions to prevent traumatic birth experience, an escalation of psychopathology during the peripartum period, and adverse infant outcomes, which in turn may prevent transgenerational transmission of trauma in the long term.Peer Reviewe

Subjective Birth Experience Predicts Mother–Infant Bonding Difficulties in Women With Mental Disorders

Background: The subjective experience of giving birth to a child varies considerably depending on psychological, medical, situational, relational, and other individual characteristics. In turn, it may have an impact on postpartum maternal mental health and family relationships, such as mother–infant bonding. The objective of the study was to evaluate the relevance of the subjective birth experience (SBE) for mother–infant bonding difficulties (BD) in women with mental disorders. - Methods: This study used data from N = 141 mothers who were treated for postpartum mental disorders in the mother–baby day unit of the Psychosomatic University Clinic in Dresden, Germany. Patients' mental status at admission and discharge was routinely examined using a diagnostic interview (SCID I) and standard psychometric questionnaires (e.g., EPDS, BSI, PBQ). Both, the SBE (assessed by Salmon's Item List, SIL) as well as medical complications (MC) were assessed retrospectively by self-report. The predictive value of SBE, MC, as well as psychopathological symptoms for mother–infant BD were evaluated using logistic regression analyses. - Results: About half of this clinical sample (47.2%) reported a negative SBE; 56.8% of all mothers presented with severe mother–infant BD toward the baby. Mothers with BD showed not only significantly more depressiveness (EPDS: M = 16.6 ± 5.6 vs. 14.4 ± 6.2*), anxiety (STAI: M = 57.2 ± 10.6 vs. 51.4 ± 10.6***), and general psychopathology (BSI-GSI: M = 1.4 ± 0.7 vs. 1.1 ± 0.6**) compared to women without BD, but also a significantly more negative SBE (SIL: M = 79.3 ± 16.2 vs. 61.3 ± 22.9***). Moreover, the SBE was the most powerful predictor for BD in univariate and multiple logistic regression analyses [OR = 0.96*** (95% CI 0.94–0.98) vs. OR = 0.96** (95% CI 0.93–0.98)], even when univariate significant predictors (e.g., current psychopathology and MC during birth) were controlled. - Conclusions: A negative SBE is strongly associated with mother–infant bonding in patients with postpartum mental disorders. It needs to get targeted within postpartum treatment, preferably in settings including both mother and child, to improve distorted mother–infant bonding processes and prevent long-term risks for the newborn. Furthermore, the results highlight the importance of focusing on the specific needs of vulnerable women prior to and during birth (e.g., emotional safety, good communication, and support) as well as individual factors that might be predictive for a negative SBE

Pre-aging of the Olfactory Bulb in Major Depression With High Comorbidity of Mental Disorders

Recent studies suggest that accelerated aging of the brain is a neuroanatomical signature of the state of mental diseases. In major depression, this pre-aging effect is negatively associated with the duration since the first onset of the disease. The olfactory bulb (OB) shrinks with age in healthy subjects and patients with mental diseases show reduced OB volumes, especially those with major depression. It is unclear whether this OB reduction in mental diseases resembles a pre-aging process and whether it is associated to the duration since the onset of the mental disease. To this aim, we investigated OB volume in 73 patients (mean-age 40.4 years, SD = 12.1 years, 57 women) with major depression and mixed comorbid mental diseases (diagnoses ranged from 1 to 6, median: 3) and 51 healthy controls (mean-age 39.2 years, SD = 13.0 years, 26 women) matched for age and sex. Patient’s first onset of disease ranged from 15 to 53 years (mean 24.2 years). All participants underwent structural MR imaging with a spin-echo T2-wheighted sequence covering the anterior and middle segments of the skull base. All results were corrected for total intracranial volume (TIV) and sex. Individual OB volume was calculated by planimetric manual contouring and the pronounced diameter change in transition from bulb to tract was used as the distal demarcation of the OB. Inter-rater correlation between two independent persons analyzing the data was high (IRC = 0.81, p < 0.005). An age-dependent decline of the OB volume was confirmed in healthy controls (r = −0.34, p < 0.05). However, this pattern was altered in patients where the OB volume was not related to age, but to the duration since the onset of the mental disease (r = −0.25, p < 0.05). This association remained stable when controlling for age. Additionally, analyses of age sub-groups revealed that the association between duration since the onset of the mental disease and OB volume was mainly driven by the group aged 50 years and above (r = −0.68; p < 0.01). We conclude that there are time windows where the OB volume is susceptible for the effects of a mental disease, e.g., depression. These effects result in cumulative pre-aging in the OB in older patients with mental diseases

Effect of mesograzer and nutrient levels on the induction of defenses in several Brazilian acroalgae

Herbivory can greatly modify benthic community structure by affecting the distribution of algal species. To deter herbivores, algae have developed several mechanisms, including the induction of chemical and morphological defenses, which may be influenced by nutrient availability. We tested 4 red (Chondrophycus flagellifera, Cryptonemia seminervis, Osmundaria obtusiloba, Pterocladiella capillacea), 4 brown (Dictyota menstrualis, Lobophora variegata, Sargassum vulgare, Stypopodium zonale), and 1 green (Codium decorticatum) algae for inducible defenses following exposure to direct consumption by an amphipod community dominated by Elasmopus brasiliensis. In addition, the effects of water-borne cues from nearby grazed conspecifics and non-grazing consumers on the induction of defenses were examined in C. decorticatum under natural and enhanced (200% natural) nutrient levels. Induction of defense was assessed in choice-feeding assays, using live algae or artificial food containing non-polar extracts of amphipod-exposed (treated) and non-exposed (control) algae. Palatability levels, estimated as the relative difference in wet mass due to consumption in feeding assays between grazer-exposed and control plants, declined significantly in 3 species after the acclimatization period. Tissue from the directly consumed red alga P. capillacea (live alga) was significantly less palatable than tissue from the control plants. Likewise, a significant effect was observed in the brown alga L. variegata. Similar, although not statistically significant, trends were observed in 6 other species. For the green alga C. decorticatum, nutrient enrichment did not affect induction of defenses by herbivores, yet unfertilized plants were more palatable than fertilized conspecifics

Entwicklungen in der Reproduktionsmedizin: mit welchen Konsequenzen müssen wir uns auseinandersetzen?

'Der vorliegende Artikel soll einen Überblick über verschiedene Aspekte der modernen Reproduktionsmedizin ermöglichen. Auf folgende Schwerpunkte wird deshalb genauer eingegangen: Entwicklung der medizinischen Möglichkeiten, Wissen in der Bevölkerung, Einschätzung von Chancen und Gefahren, psychologische Aspekte der Kinderlosigkeit, Belastungen während einer IVF-Behandlung, ethisch-moralische Konsequenzen der Verfahren. Darüber hinaus werden Zusammenhänge zwischen demographischer und medizinischer Entwicklung sowie die sich daraus ergebenden spezifischen psychologischen und soziologischen Perspektiven aufgezeigt. Die bisherigen Forschungsergebnisse zeigen nicht nur ein Mangel an Wissen bzgl. fortpflanzungsmedizinischer Aspekte, sondern auch übertrieben große, zum Teil unberechtigte, Hoffnungen hinsichtlich der Wirksamkeit der reproduktionsmedizinischen Verfahren. Oftmals werden hochaufwändige und kostenintensive Verfahren eingesetzt, um den (langen) Wunsch nach einem Kind zu erfüllen, allerdings ohne psychischen und sozialen Wirkfaktoren Rechnung zu tragen. Somit steht die Devise 'ein Kind um jeden Preis' seitens vieler Paare und aber auch Reproduktionsmediziner im krassen Gegensatz zu mangelnder Beratung vor, während und nach einer Behandlung.' (Autorenreferat)'This report gives an overview about certain aspects of modern reproductive medicine. The following issues are prioritised: development of medical facilities, people's knowledge on reproductive medicine, appraisal of chances and risks, psychological aspects of involuntary childlessness, stresses and strains during IVF-treatment, ethical consequences of these medical procedures. Furthermore interactions between demographic and medical developments are analysed as well as resulting psychological and sociological perspectives. Previous research results present both a lack of knowledge towards reproductive medical treatments and disproportionate expectations and hope toward treatment-outcome. Very often expensive and complex methods are practiced to fulfil the child wish, but mental and social aspects remain unconsidered. So the motto 'a child at any cost' on the part of many involuntary childless couples as well as of some fertility doctors poses a glaring contradiction to insufficient counselling in practice prior to, during and after the treatment.'

Peripheral serotonin transporter DNA methylation is linked to increased salience network connectivity in females with anorexia nervosa

Background: Epigenetic variation in the serotonin transporter gene (SLC6A4) has been shown to modulate the functioning of brain circuitry associated with the salience network and may heighten the risk for mental illness. This study is, to our knowledge, the first to test this epigenome–brain–behaviour pathway in patients with anorexia nervosa.Methods: We obtained resting-state functional connectivity (rsFC) data and blood samples from 55 acutely underweight female patients with anorexia nervosa and 55 age-matched female healthy controls. We decomposed imaging data using independent component analysis. We used bisulfite pyrosequencing to analyze blood DNA methylation within the promoter region of SLC6A4. We then explored salience network rsFC patterns in the group × methylation interaction.Results: We identified a positive relationship between SLC6A4 methylation levels and rsFC between the dorsolateral prefrontal cortex and the salience network in patients with anorexia nervosa compared to healthy controls. Increased rsFC in the salience network mediated the link between SLC6A4 methylation and eating disorder symptoms in patients with anorexia nervosa. We confirmed findings of rsFC alterations for CpG-specific methylation at a locus with evidence of methylation correspondence between brain and blood tissue.Limitations: This study was cross-sectional in nature, the sample size was modest for the method and methylation levels were measured peripherally, so findings cannot be fully generalized to brain tissue.Conclusion: This study sheds light on the neurobiological process of how epigenetic variation in the SLC6A4 gene may relate to rsFC in the salience network that is linked to psychopathology in anorexia nervosa.</p

Heart rate variability biofeedback in patients with alcohol dependence: a randomized controlled study

Background and objective In patients with alcohol dependence, ethyl-toxic damage of vasomotor and cardiac autonomic nerve fibers leads to autonomic imbalance with neurovascular and cardiac dysfunction, the latter resulting in reduced heart rate variability (HRV). Autonomic imbalance is linked to increased craving and cardiovascular mortality. In this study, we sought to assess the effects of HRV biofeedback training on HRV, vasomotor function, craving, and anxiety. Methods: We conducted a randomized controlled study in 48 patients (14 females, ages 25–59 years) undergoing inpatient rehabilitation treatment. In the treatment group, patients (n=24) attended six sessions of HRV biofeedback over 2 weeks in addition to standard rehabilitative care, whereas, in the control group, subjects received standard care only. Psychometric testing for craving (Obsessive Compulsive Drinking Scale), anxiety (Symptom Checklist-90-Revised), HRV assessment using coefficient of variation of R-R intervals (CVNN) analysis, and vasomotor function assessment using laser Doppler flowmetry were performed at baseline, immediately after completion of treatment or control period, and 3 and 6 weeks afterward (follow-ups 1 and 2). Results: Psychometric testing showed decreased craving in the biofeedback group immediately postintervention (OCDS scores: 8.6±7.9 post-biofeedback versus 13.7±11.0 baseline [mean ± standard deviation], P<0.05), whereas craving was unchanged at this time point in the control group. Anxiety was reduced at follow-ups 1 and 2 post-biofeedback, but was unchanged in the control group (P<0.05). Following biofeedback, CVNN tended to be increased (10.3%±2.8% post-biofeedback, 10.1%±3.5% follow-up 1, 10.1%±2.9% follow-up 2 versus 9.7%±3.6% baseline; P=not significant). There was no such trend in the control group. Vasomotor function assessed using the mean duration to 50% vasoconstriction of cutaneous vessels after deep inspiration was improved following biofeedback immediately postintervention and was unchanged in the control group (P<0.05). Conclusion: Our data indicate that HRV biofeedback might be useful to decrease anxiety, increase HRV, and improve vasomotor function in patients with alcohol dependence when complementing standard rehabilitative inpatient care

Effect of short-term heart rate variability biofeedback on long-term abstinence in alcohol dependent patients – a one-year follow-up

Background: A randomized controlled study (RCT) recently showed that short-term heart rate variability (HRV) biofeedback in addition to standard rehabilitation care for alcohol dependence can reduce craving, anxiety and improve cardiovascular autonomic function. In this one-year follow-up study we aimed to explore whether completion of 2-week HRV-Biofeedback training is associated with long-term abstinence. Furthermore, we sought to identify potential predictors of post-treatment abstinence. Methods: We conducted a survey on abstinence in patients with alcohol dependence 1 year after completion of an RCT comparing HRV-biofeedback in addition to inpatient rehabilitation treatment alone (controls). Abstinence rates were compared and analysed for association with demographic data as well as psychometric and autonomic cardiac assessment before and after completion of the biofeedback training using bivariate and multivariate regression analyses. Results: Out of 48 patients who participated in the RCT, 27 patients (9 females, ages 42.9 ± 8.6, mean ± SD) completed our one-year follow-up. When including in the analysis only patients who completed follow-up, the rate of abstinence tended to be higher in patients who underwent HRV-biofeedback 1 year earlier compared to those who received rehabilitative treatment alone (66.7% vs 50%, p = ns). This non-significant trend was also observed in the intention-to-treat analysis where patients who did not participate in the follow-up were assumed to have relapsed (46,7% biofeedback vs. 33.3% controls, p = ns). Neither cardiac autonomic function nor psychometric variables were associated with abstinence 1 year after HRV-biofeedback. Conclusion: Our follow-up study provide a first indication of possible increase in long-term abstinence after HRV-biofeedback for alcohol dependence in addition to rehabilitation. Trial registration The original randomized controlled trial was registered in the German Clinical Trials Register (DRKS00004618). This one-year follow-up survey has not been registered
