RESUMEN

OBJECTIVE: Inflammatory bowel diseases (IBD) are accompanied by symptoms that can vastly affect patients' representations of their bodies. The aim of this study was to investigate alterations in body evaluation and body ownership in IBD and their link to interoceptive sensibility, gastrointestinal-specific anxiety, and history of childhood maltreatment. METHODS: Body evaluation and ownership was assessed in 41 clinically remitted patients with IBD and 44 healthy controls (HC) using a topographical self-report method. Interoceptive sensibility, gastrointestinal-specific anxiety and a history of childhood maltreatment were assessed via self-report questionnaires. RESULTS: Patients reporting higher interoceptive sensibility perceived their bodies in a more positive manner. Higher gastrointestinal-specific anxiety was linked to a more negative body evaluation particularly of the abdomen in patients with IBD. Childhood maltreatment severity strengthened the positive association between interoceptive sensibility and body ownership only in those patients reporting higher trauma load. CONCLUSION: Altered body representations of areas associated with abdominal pain are linked to higher symptom-specific anxiety and lower levels of interoceptive sensibility in IBD. Particularly in patients with a history of childhood maltreatment, higher levels of interoceptive sensibility might have a beneficial effect on the patients' sense of body ownership.

RESUMEN

Dissociation is a multifaceted phenomenon that occurs in various mental disorders, including borderline personality disorder (BPD), but also in non-clinical populations. Severity of childhood trauma (abuse, neglect) plays an important role in the development of dissociation and BPD. However, the complex interplay of different dissociative symptoms, BPD features, and self-reported childhood trauma experiences is not yet fully understood. Graph-theoretical network analysis can help to better understand such multivariate interrelations. Objective: This study aimed to investigate associations between self-reported dissociation, BPD features, and childhood trauma experiences using a graph-theoretical approach. Data was collected online via international mental health platforms and research sites. N = 921 individuals (77.4% female) were included; 40% reported pathological levels of dissociation. Variables were assessed with established psychometric scales (Dissociative Experiences Scale; Personality Assessment Inventory Borderline Features Scale; Childhood Trauma Questionnaire) and analyzed within a partial correlation network. Positive bivariate correlations between all variables were found. When accounting for their mutual influence on each other, dissociation was predominantly connected to BPD features with effect sizes between rp = .028 and rp = .126, while still showing a slight unique relationship with physical neglect (rp = .044). Findings suggest close associations between dissociative experiences and BPD features. While childhood trauma plays an important role in the development of dissociation and BPD, its recall may not fully explain their current co-occurrence. Prospective studies are needed to shed more light on causal pathways to better understand which factors contribute to dissociation and its link to BPD (features).

RESUMEN

GOAL: The aim of this study was to investigate the network of biopsychosocial factors and quality of life (QoL) in persons with inflammatory bowel diseases (IBDs) and explore the influence of psychological factors on the course of the disease. BACKGROUND: QoL of persons with IBD depends on disease activity but also on numerous interacting psychosocial factors. The influence of psychosocial factors on the disease course in controversially discussed. MATERIALS AND METHODS: In 2 independent IBD samples (sample 1: n=209, anonymous internet survey; sample 2: n=84, outpatients with active disease), we measured QoL, anxiety, depression, illness identity, self-esteem, loneliness, childhood trauma, and visceral sensitivity with questionnaires. In addition, fatigue, hemoglobin levels, and response to therapy were assessed in sample 2. We estimated multiple regularized partial correlation networks and conducted accuracy and stability tests of the networks. RESULTS: In both samples, QoL had the strongest relationships with visceral sensitivity and the illness identity engulfment. Depression was the most central factor in the networks. Baseline depression scores, visceral sensitivity, and engulfment were associated with response to therapy in sample 2. CONCLUSIONS: This first network study to assess the interplay between biopsychosocial factors and QoL in IBD reveals a comparable network structure in 2 samples. Results partly replicate findings from previous studies with regard to the importance of depression and yield information on the central role of the newly introduced concepts of illness identity and visceral sensitivity. Preliminary findings point to an influence of these parameters on the disease course, which indicates their role as a possible target in individualized therapy.

RESUMEN

BACKGROUND: Extraintestinal symptoms are common in inflammatory bowel diseases (IBD) and include depression and fatigue. These are highly prevalent especially in active disease, potentially due to inflammation-mediated changes in the microbiota-gut-brain axis. The aim of this study was to investigate the associations between structural and functional microbiota characteristics and severity of fatigue and depressive symptoms in patients with active IBD. METHODS: We included clinical data of 62 prospectively enrolled patients with IBD in an active disease state. Patients supplied stool samples and completed the questionnaires regarding depression and fatigue symptoms. Based on taxonomic and functional metagenomic profiles of faecal gut microbiota, we used Bayesian statistics to investigate the associative networks and triangle motifs between bacterial genera, functional modules and symptom severity of self-reported fatigue and depression. RESULTS: Associations with moderate to strong evidence were found for 3 genera (Odoribacter, Anaerotruncus and Alistipes) and 3 functional modules (pectin, glycosaminoglycan and central carbohydrate metabolism) with regard to depression and for 4 genera (Intestinimonas, Anaerotruncus, Eubacterium and Clostridiales g.i.s) and 2 functional modules implicating amino acid and central carbohydrate metabolism with regard to fatigue. CONCLUSIONS: This study provides the first evidence of association triplets between microbiota composition, function and extraintestinal symptoms in active IBD. Depression and fatigue were associated with lower abundances of short-chain fatty acid producers and distinct pathways implicating glycan, carbohydrate and amino acid metabolism. Our results suggest that microbiota-directed therapeutic approaches may reduce fatigue and depression in IBD and should be investigated in future research.

RESUMEN

BACKGROUND: The COVID-19 pandemic represents a significant psychological burden for many people; however, especially during the first wave of the pandemic in Germany, little acute professional help was available for people in need. OBJECTIVE: In southern Germany, a telephone hotline for psychological first aid for COVID-19-related burdens was set up under the lead of the Baden-Wuerttemberg Ministry of Social Affairs and Integration, opened to the entire population and evaluated in April 2020. MATERIAL AND METHODS: In the period from 22 April to 24 July 2020, 753 volunteer psychotherapeutically trained counselors from different professional groups answered a total of 8096 calls. RESULTS: Depression symptoms (36%), anxiety symptoms (18%) and psychotic symptoms (19%) were most frequently reported. Every second call was related to a previous mental illness. During the counseling sessions, which lasted 25 min on average, a variety of psychological acute interventions were conducted. In the presence of unclear symptoms, psychotic symptoms or severe personality disorder symptoms, the counselors were able to help significantly less compared to the remaining calls in which other clearly defined symptoms were present. CONCLUSION: The results point to both the benefits and limitations of hotline services. The major benefits relate to the fast availability and effective professional help for people with clearly characterized symptoms. In the case of unclear or complex symptoms, immediate help by telephone seems to be possible only to a limited extent, but it could initiate access to further help offers. Overall, the results of this study provide a first indication that hotline services for psychological first aid are feasible under pandemic conditions.

RESUMEN

A major tenet in theoretical neuroscience is that cognitive and behavioral processes are ultimately implemented in terms of the neural system dynamics. Accordingly, a major aim for the analysis of neurophysiological measurements should lie in the identification of the computational dynamics underlying task processing. Here we advance a state space model (SSM) based on generative piecewise-linear recurrent neural networks (PLRNN) to assess dynamics from neuroimaging data. In contrast to many other nonlinear time series models which have been proposed for reconstructing latent dynamics, our model is easily interpretable in neural terms, amenable to systematic dynamical systems analysis of the resulting set of equations, and can straightforwardly be transformed into an equivalent continuous-time dynamical system. The major contributions of this paper are the introduction of a new observation model suitable for functional magnetic resonance imaging (fMRI) coupled to the latent PLRNN, an efficient stepwise training procedure that forces the latent model to capture the 'true' underlying dynamics rather than just fitting (or predicting) the observations, and of an empirical measure based on the Kullback-Leibler divergence to evaluate from empirical time series how well this goal of approximating the underlying dynamics has been achieved. We validate and illustrate the power of our approach on simulated 'ground-truth' dynamical systems as well as on experimental fMRI time series, and demonstrate that the learnt dynamics harbors task-related nonlinear structure that a linear dynamical model fails to capture. Given that fMRI is one of the most common techniques for measuring brain activity non-invasively in human subjects, this approach may provide a novel step toward analyzing aberrant (nonlinear) dynamics for clinical assessment or neuroscientific research.

RESUMEN

BACKGROUND: Emotion dysregulation is a core feature of borderline personality disorder (BPD), which often co-occurs with posttraumatic stress disorder (PTSD). Difficulties in emotion regulation (ER) have been linked to lower high-frequency heart rate variability (HF-HRV), a measure of autonomous nervous system functioning. However, previous research on vagally-mediated heart rate in BPD revealed heterogeneous findings and the effects of comorbid PTSD and dissociation on HF-HRV are not yet completely understood. This study aim to investigate HF-HRV during resting-state and an ER task in female BPD patients with comorbid PTSD (BPD + PTSD), patients without this comorbidity (BPD), and healthy controls (HC). METHODS: 57 BPD patients (BPD: n = 37, BPD + PTSD: n = 20) and 27 HC performed an ER task with neutral, positive, and negative images. Participants were instructed to either attend these pictures or to down-regulate their upcoming emotions using cognitive reappraisal. Subjective arousal and wellbeing, self-reported dissociation, and electrocardiogram data were assessed. RESULTS: Independent of ER instruction and picture valence, both patient groups (BPD and BPD + PTSD) reported higher subjective arousal and lower wellbeing; patients with BPD + PTSD further exhibited significantly lower HF-HRV compared with the other groups. Higher self-reported state dissociation predicted higher HF-HRV during down-regulating v. attending negative pictures in BPD + PTSD. CONCLUSIONS: Findings suggest increased emotional reactivity to negative, positive, and neutral pictures, but do not provide evidence for deficits in instructed ER in BPD. Reduced HF-HRV appears to be particularly linked to comorbid PTSD, while dissociation may underlie attempts to increase ER and HF-HRV in BPD patients with this comorbidity.

RESUMEN

BACKGROUND: Fear responses are particularly intense and persistent in post-traumatic stress disorder (PTSD), and can be evoked by unspecific cues that resemble the original traumatic event. Overgeneralisation of fear might be one of the underlying mechanisms. We investigated the generalisation and discrimination of fear in individuals with and without PTSD related to prolonged childhood maltreatment. METHODS: Sixty trauma-exposed women with (N = 30) and without (N = 30) PTSD and 30 healthy control participants (HC) underwent a fear conditioning and generalisation paradigm. In a contingency learning procedure, one of two circles of different sizes was associated with an electrical shock (danger cue), while the other circle represented a safety cue. During generalisation testing, online risk ratings, reaction times and fear-potentiated startle were measured in response to safety and danger cues as well as to eight generalisation stimuli, i.e. circles of parametrically varying size creating a continuum of similarity between the danger and safety cue. RESULTS: The increase in reaction times from the safety cue across the different generalisation classes to the danger cue was less pronounced in PTSD compared with HC. Moreover, PTSD participants expected higher risk of an aversive event independent of stimulus types and task. CONCLUSIONS: Alterations in generalisation constitute one part of fear memory alterations in PTSD. Neither the accuracy of a risk judgement nor the strength of the induced fear was affected. Instead, processing times as an index of uncertainty during risk judgements suggested a reduced differentiation between safety and threat in PTSD.

RESUMEN

Affective hyper-reactivity and impaired cognitive control of emotional material are core features of borderline personality disorder (BPD). A high percentage of individuals with BPD experience stress-related dissociation, including emotional numbing and memory disruptions. So far little is known about how dissociation influences the neural processing of emotional material in the context of a working memory task in BPD. We aimed to investigate whole-brain activity and amygdala functional connectivity (FC) during an Emotional Working Memory Task (EWMT) after dissociation induction in un-medicated BPD patients compared to healthy controls (HC). Using script-driven imagery, dissociation was induced in 17 patients ('BPD_D'), while 12 patients ('BPD_N') and 18 HC were exposed to neutral scripts during fMRI. Afterwards, participants performed the EWMT with neutral vs. negative IAPS pictures vs. no distractors. Main outcome measures were behavioral performance (reaction times, errors) and whole-brain activity during the EWMT. Psychophysiological interaction analysis was used to examine amygdala connectivity during emotional distraction. BPD patients after dissociation induction showed overall WM impairments, a deactivation in bilateral amygdala, and lower activity in left cuneus, lingual gyrus, and posterior cingulate than BPD_N, along with stronger left inferior frontal gyrus activity than HC. Furthermore, reduced amygdala FC with fusiform gyrus and stronger amygdala FC with right middle/superior temporal gyrus and left inferior parietal lobule was observed in BPD_D. Findings suggest that dissociation affects reactivity to emotionally salient material and WM. Altered activity in areas associated with emotion processing, memory, and self-referential processes may contribute to dissociative states in BPD.

RESUMEN

INTRODUCTION: Interpersonal problems together with feelings of intense loneliness constitute a core symptom domain in borderline personality disorder (BPD). Mimicry is one social behaviour that serves the forming of social affiliation and building a sense of belonging. In the present study, we investigated whether behavioural mimicry is altered in BPD and whether it is linked to the patient's feeling of loneliness. METHODS: Individuals with BPD (N = 26) and healthy participants (HC, N = 25) performed a finger tapping task with a congruent or incongruent finger movement displayed preceding the presentation of the task relevant stimulus. Additional trials showing an immobile hand were used as a control condition. Mimicry strength was estimated as response facilitation after congruent and response interference after incongruent cues. RESULTS: Both HC and BPD patients showed facilitated responses after congruent finger movements. Only BPD patients exhibited interference by incongruent cues. The lonelier the BPD patients felt, the weaker was the interference of the incongruent cues. In contrast, interference increased with the level of loneliness in the HC group. CONCLUSIONS: Behavioural mimicry was increased in BPD. However, this effect was less pronounced in those BPD patients who reported the highest levels of loneliness. Our findings emphasize that mimicry is a complex construct and only some of the involved processes are altered in BPD. Future studies must further disentangle the contribution of cognitive and social cognitive processes, address a potential causality in the link between loneliness and mimicry in BPD, and relate alterations of mimicry to interpersonal dysfunction during every-day life.

RESUMEN

PURPOSE: To evaluate changes in hemodynamic effects of intramyometrial epinephrine injection for blood loss reduction in laparoscopic myomectomy. METHODS: A total of 185 women with symptomatic uterine fibroids who underwent laparoscopic myomectomy were enrolled in this study. Eighty-six women (study collective) received an intramyometrial injection of epinephrine and were compared to ninety-nine women (control collective) who underwent laparoscopic myomectomy without an intramyometrial epinephrine injection. Demographic parameters, change of hemodynamic parameters during surgery as well as hemoglobin drop after surgery were analyzed. RESULTS: In the study collective maximum systolic blood pressure (p < 0.001), maximum increase of the systolic blood pressure within 5 min (p = 0.003), duration of hypertension (p = 0.012), maximal (p < 0.001) and mean heart rate (p = 0.005), maximal increase of heart rate within 5 min (p = 0.003) and difference of mean to maximal heart rate (p < 0.001) were higher compared to the control collective. There was no difference in pre- and postoperative hemoglobin levels in both collectives and no intraoperative clinically relevant complication occurred due to intramyometrial epinephrine injection. CONCLUSION: The intramyometrial application of epinephrine seems to be safe but leads to significant alterations of hemodynamic parameters without a significant change in postoperative hemoglobin levels.

RESUMEN

PURPOSE: To investigate psychosocial and biological parameters that may influence decision-making concerning the mode of delivery in women with caesarean section on maternal request (CSMR). METHODS: Two hundred and two women were enrolled prospectively. The study sample (n = 93) consisted of women who aimed for CSMR, the control sample were women who seeked for vaginal delivery (n = 109). Parturients of both samples were enrolled during the pre-birth counselling at the delivery room at the University Medical Centre Mannheim, University Heidelberg, Germany. Women completed standardised questionnaires regarding psychosocial burden (SCL-R 90), fear of childbirth (W-DEQ) and anxiety (STAI), personality structure (HEXACO-Pi-R), and ambiguity tolerance (PFI, PNS, and NFC), social support (F-SozU) as well as one questionnaire assessing demographic parameters and further factors potentially influencing their choice of the mode of delivery. Hair cortisol concentration as a marker for chronic psychological stress and pressure pain threshold with a pressure algometer was assessed. RESULTS: Women in the CSMR sample had less social support (F-SozU: 2.99 ± 0.52 vs. 3.12 ± 0.32; p = 0.043) and were less educated (high school or university degree: 37 vs. 71%, p = 0.001) compared to parturients of the control sample. Women who underwent CSMR were less open-minded (HEXACO-Pi-R: 3.08 ± 0.57 vs. 3.26 ± 0.50; p = 0.016) and less extroverted (HEXACO-Pi-R: 3.34 ± 0.36 vs. 3.46 ± 0.41; p = 0.041). The control collective showed higher scores in negative appraisal of the birth ('W-DEQ-negative appraisal': 2.5 ± 0.8 vs. 2.2 ± 0.9; p = 0.006), whereas "lack of positive anticipation" was higher in the study collective ('W-DEQ-lack of positive anticipation': 3.2 ± 1.2 vs. 2.8 ± 0.8; p = 0.015). The study collective had higher pressure pain threshold values (5.07 ± 2.06 vs. 4.35 ± 1.38; p = 0.007), while no significant differences were observed in hair cortisol concentration comparing both groups (5.0 ± 11.4 vs. 4.9 ± 8.3; p = 0.426). The majority of the control collective (80%) had chosen the vaginal route as their mode of delivery before pregnancy, whereas only 21% of the women in the study collective decided to undergo CSMR before conception. The advice of social sources including both medical and non-medical aspects was rated less important in the study sample, with significant differences indicating a lower relevance of counsel from friends (p = 0.002) and midwives (p < 0.001). CONCLUSION: Women who inquired a CSMR had lower social support, were less educated, more anxious, and had a lower sensitivity for physical pain compared to women seeking for spontaneous delivery. This should be considered when counselling women requiring CSMR and could be leverage points to intervene to reduce the continuously increasing CSMR rate.

RESUMEN

PURPOSE: To analyse post-partum short- and long-term pain sensitivity and the influence of endogenous pain inhibition as well as distinct psycho-social factors on birth-related pain. METHODS: Pain sensitivity was assessed in 91 primiparous women at three times: 2-6 weeks before, one to 3 days as well as ten to 14 weeks after childbirth. Application of a pressure algometer in combination with a cold pressor test was utilised for measurement of pain sensitivity and assessment of conditioned pain modulation (CPM). Selected psycho-social factors (anxiety, social support, history of abuse, chronic pain and fear of childbirth) were evaluated with standardised questionnaires and their effect on pain processing then analysed. RESULTS: Pressure pain threshold, cold pain threshold and cold pain tolerance increased significantly directly after birth (all p < 0.001). While cold pain parameters partly recovered on follow-up, pressure pain threshold remained increased above baseline (p < 0.001). These pain-modulating effects were not found for women with history of abuse. While CPM was not affected by birth, its extent correlated significantly (r = 0.367) with the drop in pain sensitivity following birth. Moreover, high trait anxiety predicted an attenuated reduction in pain sensitivity (r = 0.357), while there was no correlation with fear of childbirth, chronic pain and social support. CONCLUSION: Pain sensitivity showed a decrease when comparing post-partum with prepartum values. The extent and direction of CPM appear to be a trait variable that predicted post-partum hypalgesia without being changed itself. Post-partum hypalgesia was reduced in women with a history of abuse and high trait anxiety, which suggests that individual differences in CPM affect childbirth experience.

RESUMEN

AIM: To evaluate postoperative sexual functioning and the influence of patients' expectations on the change in sexuality following laparoscopic total (TLH) versus subtotal hysterectomy (LASH). METHODS: A total of 120 women undergoing laparoscopic hysterectomy were preoperatively enrolled in this bicentric prospective study. Sexual functioning (SF) was evaluated using the female sexual function index (FSFI). Additionally, participants filled in a standardised questionnaire concerning expected changes in SF after surgery. At 3, 6 and 12 months following surgery, women were asked again to assess their level of SF (FSFI). Data of women who participated in at least one FSFI follow-up assessment were analysed (n = 92). We compared the change in SF after surgery between patients with TLH (n = 46) and LASH (n = 46). Additionally, we calculated regression analyses with the patients' expectations as a predictor for change in FSFI scores. RESULTS: Comparing the change of FSFI scores after surgery in both collectives revealed differences only 3 months after surgery, as improvement was stronger for the LASH collective compared to the THL group (p = 0.006). There were no changes comparing collectives after 6 (p = 0.663) and 12 (p = 0.326) months. Concerning patients' expectations, for the LASH group baseline SF (p < 0.001), but not expectations (p = 0.567) predicted the strength of change at each of the follow ups: a lower level of baseline SF was linked to a stronger improvement after surgery. For the THL collective, both baseline SF (p < 0.001) as well as patients' expectations (3 months: p = 0.077, 6 months: p = 0.37, 12 months: p = 0.024) predicted the strength of change: both, a lower level of baseline SF and higher expectations towards an improvement predicted a stronger improvement. CONCLUSION: The preservation of the cervix does not show an advantage in improving SF after surgery. Both methods induce a comparable improvement in long-time SF, especially in patients with an impaired sexuality pre-surgery. Furthermore, patients' expectations concerning this matter seem to have an impact on the postoperative outcome; therefore, this circumstance should be considered in future projects.

RESUMEN

Self-conscious emotions, such as guilt, shame, or self-disgust, as well as self-related motives, such as self-enhancement or self-verification, influence how people perceive, evaluate, memorize, and respond to self-related information. They not only influence peoples' concepts of themselves but may also affect their behavior in social environments. In the current review, we describe alterations of self-related processing in borderline personality disorder (BPD). We chose BPD as an example of a mental disorder of which impairments in self-functioning and identity constitute a major feature. Since terminology used in clinical research on self-referential processing is diverse and often confusing, we start with reviewing some of the main concepts in this area of research using a conceptual framework provided from social psychology. Most studies on self-referential processing in BPD focused on descriptions of self-esteem and revealed a negative self-concept, particularly expressed by explicitly reported low self-esteem. Moreover, self-esteem is unstable in BPD and likely reactive to self-relevant cues. BPD patients are prone to negative emotions with respect to themselves, such as self-disgust and shame. First data point to altered self-related motives, too. In conclusion, although explicit self-esteem is widely studied as a global and trait-like feature of BPD, there is a strong lack of studies that take the complexity of the construct self-esteem into account. Further studies on alterations in self-related processes are required to deepen our understanding of impairments of the self-concept in BPD and enable the improvement of psychosocial therapeutic approaches.

RESUMEN

PURPOSE: To evaluate sexual functioning and expected changes in sexual functioning in women with planned total versus subtotal laparoscopic hysterectomy. METHODS: A total of 120 women undergoing laparoscopic hysterectomy were preoperatively enrolled in this study with a cross-sectional design. Full data sets were available for 112 patients, so that 56 patients with planned total laparoscopic hysterectomy (TLH) and 56 women with planned laparoscopic supracervical hysterectomy (LASH) were preoperatively assessed. Sexual functioning was evaluated using the female sexual function index (FSFI). Additionally, participants filled in a standardised questionnaire concerning expected changes on sexual function after the procedure. Demographic parameters, expectations concerning postoperative sexuality and FSFI scores were analysed and compared in women undergoing TLH and LASH. RESULTS: There were no significant differences concerning demographic parameters and FSFI scores comparing collectives. Sexuality in general was considered more important in women undergoing LASH (2.88 ± 0.83 vs. 2.48 ± 0.89; p = 0.011). Also, in 29 patients (52%) opting for LASH and 8 (14%) patients undergoing TLH a potential change in postoperative sexuality had an impact on their choice for a subtotal/total hysterectomy, respectively (p < 0.001). CONCLUSION: Patients' expectations concerning preservation of the cervix and postoperative sexuality appear to have the potential to bias investigations comparing total with subtotal hysterectomy. Hence, future research focusing on this issue should be accomplished incorporating patients' expectations stratified by mode of intervention.

RESUMEN

PURPOSE: To investigate sociopsychological factors of women undergoing a caesarean section on maternal request (CSMR). METHODS: Twenty-eight women who underwent CSMR and 29 women with vaginal delivery (VD) filled in standardized questionnaires concerning psychological burden (SCL-R 90), fear of childbirth (W-DEQ, STAI), personality structure (HEXACO-Pi-R) and social support (F-SozU) as well as one questionnaire assessing potential factors influencing their mode of delivery. RESULTS: Women with CSMR were older (36.5 ± 5.4 vs. 30.6 ± 5.2 years; p < 0.001) and suffered more from fear of childbirth (W-DEQ 4.3 ± 0.8 vs. 3.7 ± 1.2; p = 0.041), concerns for their child (W-DEQ 2.0 ± 1.5 vs. 1.3 ± 0.7; p = 0.026) and appraised the birth less negative (W-DEQ 2.0 ± 0.7 vs. 2.7 ± 1.1; p = 0.008). The majority of parturients had chosen their preferred mode of delivery before pregnancy (CS 61% vs. VD 82%, p = 0.328). In the decision-making process for the mode of delivery, the advice of the partner (85 and 90%) played an important role. 82% of the women who delivered via CSMR did not regret the decision for this mode of delivery. CONCLUSION: Women who underwent CS had higher fear of childbirth and appraised the birth less negative. The majority did not regret the decision for the CS and would even choose this mode of delivery for their next pregnancy. Although the partner and the physician seem to be important in the decision process for of the mode of delivery, reasons for the choice for CSMR appear to be multifactorial.

RESUMEN

BACKGROUND: Patients with borderline personality disorder frequently show non-suicidal self-injury (NSSI). In these patients, NSSI often serves to reduce high levels of stress. AIMS: Investigation of neurobiological mechanisms of NSSI in borderline personality disorder. METHOD: In total, 21 women with borderline personality disorder and 17 healthy controls underwent a stress induction, followed by either an incision into the forearm or a sham treatment. Afterwards participants underwent resting-state functional magnetic resonance imaging while aversive tension, heart rate and heart rate variability were assessed. RESULTS: We found a significant influence of incision on subjective and objective stress levels with a stronger decrease of aversive tension in the borderline personality disorder group following incision than sham. Amygdala activity decreased more and functional connectivity with superior frontal gyrus normalised after incision in the borderline personality disorder group. CONCLUSIONS: Decreased stress levels and amygdala activity after incision support the assumption of an influence of NSSI on emotion regulation in individuals with borderline personality disorder and aids in understanding why these patients use self-inflicted pain to reduce inner tension.
