Respiratory distress syndrome in near-term babies after caesarean section

OBJECTIVE: Severe respiratory distress syndrome (RDS) caused by surfactant deficiency is described not only in preterm infants but also in (near-) term babies after caesarean section (CS), especially when carried out before the onset of labour. The aim of the present study was to document the severity of this theoretically avoidable entity in order to improve obstetric and perinatal care. PATIENTS: All neonates admitted to the paediatric intensive care unit of the University Hospital of Bern between 1988 and 2000 with RDS on the basis of hyaline membrane disease (HMD) needing mechanical ventilation (MV) after CS and with a birthweight > or = 2500 g were analysed. HMD was diagnosed when respiratory distress and the typical radiological signs were present. Patients were grouped into elective CS before onset of labour and before rupture of membranes (group 1, n = 34) and patients delivered by emergency CS or CS after onset of labour or rupture of membranes (group 2, n = 22). Analysed indices for severity of illness were duration of stay in intensive care unit and MV, ventilation mode, worst oxygenation index (OI), presence of pulmonary air leak, and systemic hypotension. RESULTS: Mean gestational age (GA) was 37 2/7 weeks in group 1 and 36 2/7 weeks in group 2; no patient had a GA of > or = 39 0/7 weeks. Duration of MV was 4.4 days in group 1 and 3.9 days in group 2. Thirteen patients (38%) of group 1 and 7 (32%) of group 2 had to be managed by rescue high-frequency ventilation. A total of 7 patients had an OI>40. Eight patients (24%) in group 1 and 4 (18%) in group 2 developed a pulmonary air leak. Fourteen neonates (41%) in group 1 had to be supported by catecholamines versus 5 (22%) in group 2. There was one death in group 1. CONCLUSION: Severe RDS on the basis of HMD can also occur in near-term babies after CS; even a fatal outcome can not be excluded. The severity of illness in elective CS without labour may be quite high and is comparable to newborns delivered by CS (after onset of labour and/or rupture of the membranes) who were 1 week younger. No case of HMD was found in our population when CS was carried out after completion of 39 post-menstrual weeks of gestation.

The paradox of adult respiratory distress syndrome in neonates

Six full-term newborn infants are described who suffered from severe adult respiratory distress syndrome (ARDS). The triggering event was intrauterine/perinatal asphyxia in five, and group B streptococcal (GBS) septicemia in three. All had severe respiratory distress/failure and were ventilated mechanically with high concentrations of inspired oxygen and positive end-expiratory pressure. Radiography of the chest showed dense bilateral consolidation with air bronchograms and reduced lung volume. Persistent pulmonary hypertension (PPH) was documented in all cases. The coincidence of ARDS and PPH rendered respiratory management extremely difficult. For this reason high-frequency ventilation was instituted in all patients in order to improve CO2 elimination and induce respiratory alkalosis. Acute complications of respiratory therapy were encountered in five patients (pneumothorax, pulmonary interstitial emphysema, pneumopericardium). Three infants died (irreversible septic shock, progressive severe hypoxemia, and sudden cardiac arrest) after 17, 80, and 175 h of life. Histologic examination of the lungs was possible in all fatal cases and revealed typical changes of acute to subacute stages of ARDS. Three infants survived, the mean time of mechanical respiratory support being 703 h. Two patients were still dependent on oxygen after 1 month of life, and all survivors had increased interstitial markings and increased lung volumes on their chest roentgenograms at this time.

Is the relation between early post-session reports and treatment outcome an epiphenomenon of intake distress and early response? A multi-predictor analysis in outpatient psychotherapy

The early phase of psychotherapy has been regarded as a sensitive period in the unfolding of psychotherapy leading to positive outcomes. However, there is disagreement about the degree to which early (especially relationship-related) session experiences predict outcome over and above initial levels of distress and early response to treatment. The goal of the present study was to simultaneously examine outcome at post treatment as a function of (a) intake symptom and interpersonal distress as well as early change in well-being and symptoms, (b) the patient's early session-experiences, (c) the therapist's early session-experiences/interventions, and (d) their interactions. The data of 430 psychotherapy completers treated by 151 therapists were analyzed using hierarchical linear models. Results indicate that early positive intra- and interpersonal session experiences as reported by patients and therapists after the sessions explained 58% of variance of a composite outcome measure, taking intake distress and early response into account. All predictors (other than problem-activating therapists' interventions) contributed to later treatment outcomes if entered as single predictors. However, the multi-predictor analyses indicated that interpersonal distress at intake as well as the early interpersonal session experiences by patients and therapists remained robust predictors of outcome. The findings underscore that early in therapy therapists (and their supervisors) need to understand and monitor multiple interconnected components simultaneously

Sympathy, distress, and prosocial behavior of preschool children in four cultures

This study examined emotional responding (sympathy and distress) and prosocial behavior as well as their relations across four cultures in a specific context. Preschool children (N = 212) from two Western cultures, Germany and Israel, and two South-East Asian cultures, Indonesia and Malaysia, participated in this study. Children's emotional reactions and prosocial behavior were observed when interacting with an adult in a quasi-experimental situation. Results showed that children from the two South-East Asian cultures, as compared to children from the two Western cultures, displayed more self-focused distress and less prosocial behavior. Across cultures, a positive relation between sympathy and prosocial behavior and a negative relation between self-focused distress and prosocial behavior were found. The strengths of these relations were moderated by culture. These results are discussed with regard to their cultural meaning in the specific experimental situation as well as to general culture-specific characteristics.

Higher emotional distress in female partners of cancer patients: prevalence and patient-partner interdependencies in a 3-year cohort

OBJECTIVE: Assessment and treatment of psychological distress in cancer patients was recognized as a major challenge. The role of spouses, caregivers, and significant others became of salient importance not only because of their supportive functions but also in respect to their own burden. The purpose of this study was to assess the amount of distress in a mixed sample of cancer patients and their partners and to explore the dyadic interdependence. METHODS: An initial sample of 154 dyads was recruited, and distress questionnaires (Hospital Anxiety and Depression Scale, Symptom Checklist 9-Item Short Version and 12-Item Short Form Health Survey) were assessed over four time points. Linear mixed models and actor-partner interdependence models were applied. RESULTS: A significant proportion of patients and their partners (up to 40%) reported high levels of anxiety, depression, psychological distress, and low quality of life over the course of the investigation. Mixed model analyses revealed that higher risks for clinical relevant anxiety and depression in couples exist for female patients and especially for female partners. Although psychological strain decreased over time, the risk for elevated distress in female partners remained. Modeling patient-partner interdependence over time stratified by patients' gender revealed specific effects: a moderate correlation between distress in patients and partners, and a transmission of distress from male patients to their female partners. CONCLUSIONS: Our findings provide empirical support for gender-specific transmission of distress in dyads coping with cancer. This should be considered as an important starting point for planning systemic psycho-oncological interventions and conceptualizing further research.

Vulnerability Following a Critical Life Event: Temporary Crisis or Chronic Distress? A Psychological Controversy, Methodological Considerations, and Empirical Evidence

This contribution deals with psychological vulnerability resulting from marital breakup after a long-term relationship. Despite the existing vast body of consolidated knowledge on divorce and psychological adaptation, there are still several controversies concerning the vulnerabilizing impact of marital breakup. One major issue refers to the question of whether vulnerability after marital breakup is a temporary crisis or rather a chronic strain. In this chapter we want to present two possible methodological options to tackle this question: First, comparing a sample of almost 1000 middle-aged persons, who were married on average 19 years, and who experienced a marital split within the last 5 years (4 time groups), with a group of age-matched married controls with regard to various indicators of psychological vulnerability (such as depression and hopelessness). Second, comparing within the divorced group the most vulnerable individuals (in terms of depression, hopelessness, life satisfaction) with those who were the least affected, regarding intra-personal resources (personality, resilience), divorce circumstances, post-divorce situation, and socio-economic resources. The study results underline the vulnerabilizing impact of marital breakup, but at the same time they reveal individual differences in psychological adaptation especially due to personality, new partnership, economic resources, and last but not least due to time. Furthermore our data strongly suggest that there is not a generalized psychological vulnerability after marital breakup, but that the emotional dimensions such as depression or feelings of not overcoming the loss are more affected than the more cognitive ones such as life satisfaction.

A patient-reported outcome measure to identify occurrence and distress of post-surgery symptoms of WOMen with vulvAr Neoplasia (WOMAN-PRO) - a cross sectional study.

OBJECTIVE The aim of the study was to describe the (a) symptom experience of women with vulvar intraepithelial neoplasia and vulvar cancer (vulvar neoplasia) during the first week after hospital discharge, and (b) associations between age, type of disease, stage of disease, the extent of surgical treatment and symptom experience. METHODS This cross-sectional study was conducted in eight hospitals in Germany and Switzerland (Clinical Trial ID: NCT01300663). Symptom experience after surgical treatment in women with vulvar neoplasia was measured with our newly developed WOMAN-PRO instrument. Outpatients (n=65) rated 31 items. We used descriptive statistics and regression analysis. RESULTS The average number of symptoms reported per patient was 20.2 (SD 5.77) with a range of 5 to 31 symptoms. The three most prevalent wound-related symptoms were 'swelling' (n=56), 'drainage' (n=54) and 'pain' (n=52). The three most prevalent difficulties in daily life were 'sitting' (n=63), 'wearing clothes' (n=56) and 'carrying out my daily activities' (n=51). 'Tiredness' (n=62), 'insecurity' (n=54) and 'feeling that my body has changed' (n=50) were the three most prevalent psychosocial symptoms/issues. The most distressing symptoms were 'sitting' (Mean 2.03, SD 0.88), 'open spot (e.g. opening of skin or suture)' (Mean 1.91, SD 0.93), and 'carrying out my daily activities' (Mean 1.86, SD 0.87), which were on average reported as 'quite a bit' distressing. Negative associations were found between psychosocial symptom experience and age. CONCLUSIONS WOMAN-PRO data showed a high symptom prevalence and distress, call for a comprehensive symptom assessment, and may allow identification of relevant areas in symptom management.

Influence of inspiration to expiration ratio on cyclic recruitment and derecruitment of atelectasis in a saline lavage model of acute respiratory distress syndrome*

OBJECTIVE Cyclic recruitment and derecruitment of atelectasis can occur during mechanical ventilation, especially in injured lungs. Experimentally, cyclic recruitment and derecruitment can be quantified by respiration-dependent changes in PaO2 (ΔPaO2), reflecting the varying intrapulmonary shunt fraction within the respiratory cycle. This study investigated the effect of inspiration to expiration ratio upon ΔPaO2 and Horowitz index. DESIGN Prospective randomized study. SETTING Laboratory investigation. SUBJECTS Piglets, average weight 30 ± 2 kg. INTERVENTIONS At respiratory rate 6 breaths/min, end-inspiratory pressure (Pendinsp) 40 cm H2O, positive end-expiratory pressure 5 cm H2O, and FIO2 1.0, measurements were performed at randomly set inspiration to expiration ratios during baseline healthy and mild surfactant depletion injury. Lung damage was titrated by repetitive surfactant washout to induce maximal cyclic recruitment and derecruitment as measured by multifrequency phase fluorimetry. Regional ventilation distribution was evaluated by electrical impedance tomography. Step changes in airway pressure from 5 to 40 cm H2O and vice versa were performed after lavage to calculate PO2-based recruitment and derecruitment time constants (TAU). MEASUREMENTS AND MAIN RESULTS In baseline healthy, cyclic recruitment and derecruitment could not be provoked, whereas in model acute respiratory distress syndrome, the highest ΔPaO2 were routinely detected at an inspiration to expiration ratio of 1:4 (range, 52-277 torr [6.9-36.9 kPa]). Shorter expiration time reduced cyclic recruitment and derecruitment significantly (158 ± 85 torr [21.1 ± 11.3 kPa] [inspiration to expiration ratio, 1:4]; 25 ± 12 torr [3.3 ± 1.6 kPa] [inspiration to expiration ratio, 4:1]; p < 0.0001), whereas the PaO2/FIO2 ratio increased (267 ± 50 [inspiration to expiration ratio, 1:4]; 424 ± 53 [inspiration to expiration ratio, 4:1]; p < 0.0001). Correspondingly, regional ventilation redistributed toward dependent lung regions (p < 0.0001). Recruitment was much faster (TAU: fast 1.6 s [78%]; slow 9.2 s) than derecruitment (TAU: fast 3.1 s [87%]; slow 17.7 s) (p = 0.0078). CONCLUSIONS Inverse ratio ventilation minimizes cyclic recruitment and derecruitment of atelectasis in an experimental model of surfactant-depleted pigs. Time constants for recruitment and derecruitment, and regional ventilation distribution, reflect these findings and highlight the time dependency of cyclic recruitment and derecruitment.

General distress, hopelessness—suicidal ideation and worrying in adolescence: Concurrent and predictive validity of a symptom-level bifactor model for clinical diagnoses

BACKGROUND: Clinical disorders often share common symptoms and aetiological factors. Bifactor models acknowledge the role of an underlying general distress component and more specific sub-domains of psychopathology which specify the unique components of disorders over and above a general factor. METHODS: A bifactor model jointly calibrated data on subjective distress from The Mood and Feelings Questionnaire and the Revised Children's Manifest Anxiety Scale. The bifactor model encompassed a general distress factor, and specific factors for (a) hopelessness-suicidal ideation, (b) generalised worrying and (c) restlessness-fatigue at age 14 which were related to lifetime clinical diagnoses established by interviews at ages 14 (concurrent validity) and current diagnoses at 17 years (predictive validity) in a British population sample of 1159 adolescents. RESULTS: Diagnostic interviews confirmed the validity of a symptom-level bifactor model. The underlying general distress factor was a powerful but non-specific predictor of affective, anxiety and behaviour disorders. The specific factors for hopelessness-suicidal ideation and generalised worrying contributed to predictive specificity. Hopelessness-suicidal ideation predicted concurrent and future affective disorder; generalised worrying predicted concurrent and future anxiety, specifically concurrent generalised anxiety disorders. Generalised worrying was negatively associated with behaviour disorders. LIMITATIONS: The analyses of gender differences and the prediction of specific disorders was limited due to a low frequency of disorders other than depression. CONCLUSIONS: The bifactor model was able to differentiate concurrent and predict future clinical diagnoses. This can inform the development of targeted as well as non-specific interventions for prevention and treatment of different disorders.

Brief Report: HIV Testing Among Pregnant Women Who Attend Antenatal Care in Malawi.

Malawi adopted the Option B+ strategy in 2011. Its success in reducing mother-to-child transmission depends on coverage and timing of HIV testing. We assessed HIV status ascertainment and its predictors during pregnancy. HIV status ascertainment was 82.3% (95% confidence interval: 80.2 to 85.9) in the pre-Option B+ period and 85.7% (95% confidence interval: 83.4 to 88.0) in the Option B+ period. Higher HIV ascertainment was independently associated with higher age, attending antenatal care more than once, and registration in 2010. The observed high variability of HIV ascertainment between sites (50.6%-97.7%) and over time suggests that HIV test kit shortages and insufficient numbers of staff posed major barriers to reducing mother-to-child transmission.

Psychological distress in medical seeking ED care for somatic reasons: results of a systematic review

Objectives: The aim of this systematic literature review is to investigate (A) currently used instruments for assessing psychological distress, (B) the prevalence of psychological distress in medical emergency department (ED) patients with acute somatic conditions and (C) empirical evidence on how predictors are associated with psychological distress. Methods: We conducted an electronic literature search using three databases to identify studies that used validated instruments for detection of psychological distress in adult patients presented to the ED with somatic (non-psychiatric) complaints. From a total of 1688 potential articles, 18 studies were selected for in-depth review. Results: A total of 13 instruments have been applied for assessment of distress including screening questionnaires and briefly structured clinical interviews. Using these instruments, the prevalence of psychological distress detected in medical ED patients was between 4% and 47%. Psychological distress in general and particularly depression and anxiety have been found to be associated with demographic factors (eg, female gender, middle age) and illness-related variables (eg, urgency of triage category). Some studies reported that coexisting psychological distress of medical patients identified in the ED was associated with physical and psychological health status after ED discharge. Importantly, during routine clinical care, only few patients with psychological distress were diagnosed by their treating physicians. Conclusions: There is strong evidence that psychological distress is an important and prevalent cofactor in medically ill patients presenting to the ED with harmful associations with (subjective) health outcomes. To prove causality, future research should investigate whether screening and lowering psychological distress with specific interventions would result in better patient outcomes.

A picture paints a thousand words: Heart drawings reflect acute distress and illness perception and predict posttraumatic stress symptoms after acute myocardial infarction

The aim of this study was to examine whether heart drawings of patients with acute myocardial infarction reflect acute distress symptoms and negative illness beliefs and predict posttraumatic stress symptoms 3 months post-myocardial infarction. In total, 84 patients aged over 18 years drew pictures of their heart. The larger the area drawn as damaged, the greater were the levels of acute distress (r = 0.36; p < 0.05), negative illness perceptions (r = 0.42, p < 0.05), and posttraumatic stress symptoms (r = 0.54, p < 0.01). Pain drawings may offer a tool to identify maladaptive cognitions and thus patients at risk of posttraumatic stress disorder.

Irrational Beliefs and Psychological Distress: A Meta-Analysis

Background: Since the cognitive revolution of the early 1950s, cognitions have been discussed as central components in the understanding and treatment of mental illnesses. Even though there is an extensive literature on the association between therapy-related cognitions such as irrational beliefs and psychological distress over the past 60 years, there is little meta-analytical knowledge about the nature of this association. Methods: The relationship between irrational beliefs and distress was examined based on a systematic review that included 100 independent samples, gathered in 83 primary studies, using a random-effect model. The overall effects as well as potential moderators were examined: (a) distress measure, (b) irrational belief measure, (c) irrational belief type, (d) method of assessment of distress, (e) nature of irrational beliefs, (f) time lag between irrational beliefs and distress assessment, (g) nature of stressful events, (h) sample characteristics (i.e. age, gender, income, and educational, marital, occupational and clinical status), (i) developer/validator status of the author(s), and (k) publication year and country. Results: Overall, irrational beliefs were positively associated with various types of distress, such as general distress, anxiety, depression, anger, and guilt (omnibus: r = 0.38). The following variables were significant moderators of the relationship between the intensity of irrational beliefs and the level of distress: irrational belief measure and type, stressful event, age, educational and clinical status, and developer/validator status of the author. Conclusions: Irrational beliefs and distress are moderately connected to each other; this relationship remains significant even after controlling for several potential covariates.
