Organ Dysfunction in Children With Blood Culture-Proven Sepsis: Comparative Performance of Four Scores in a National Cohort Study.

OBJECTIVES: Previous studies applying Sepsis-3 criteria to children were based on retrospective analyses of PICU cohorts. We aimed to compare organ dysfunction criteria in children with blood culture-proven sepsis, including emergency department, PICU, and ward patients, and to assess relevance of organ dysfunctions for mortality prediction. DESIGN: We have carried out a nonprespecified, secondary analysis of a prospective dataset collected from September 2011 to December 2015. SETTING: Emergency departments, wards, and PICUs in 10 tertiary children's hospitals in Switzerland. PATIENTS: Children younger than 17 years old with blood culture-proven sepsis. We excluded preterm infants and term infants younger than 7 days old. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We compared the 2005 International Pediatric Sepsis Consensus Conference (IPSCC), Pediatric Logistic Organ Dysfunction-2 (PELOD-2), pediatric Sequential Organ Failure Assessment (pSOFA), and Pediatric Organ Dysfunction Information Update Mandate (PODIUM) scores, measured at blood culture sampling, to predict 30-day mortality. We analyzed 877 sepsis episodes in 807 children, with a 30-day mortality of 4.3%. Percentage with organ dysfunction ranged from 32.7% (IPSCC) to 55.3% (pSOFA). In adjusted analyses, the accuracy for identification of 30-day mortality was area under the curve (AUC) 0.87 (95% CI, 0.82-0.92) for IPSCC, 0.83 (0.76-0.89) for PELOD-2, 0.85 (0.78-0.92) for pSOFA, and 0.85 (0.78-0.91) for PODIUM. When restricting scores to neurologic, respiratory, and cardiovascular dysfunction, the adjusted AUC was 0.89 (0.84-0.94) for IPSCC, 0.85 (0.79-0.91) for PELOD-2, 0.87 (0.81-0.93) for pSOFA, and 0.88 (0.83-0.93) for PODIUM. CONCLUSIONS: IPSCC, PELOD-2, pSOFA, and PODIUM performed similarly to predict 30-day mortality. Simplified scores restricted to neurologic, respiratory, and cardiovascular dysfunction yielded comparable performance.

Ocrelizumab-treated patients with relapsing multiple sclerosis show volume loss rates similar to healthy aging.

BACKGROUND: Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system characterized by two major and interconnected hallmarks: inflammation and progressive neurodegeneration. OBJECTIVE: The aim of this work was to compare neurodegenerative processes, in the form of global and regional brain volume loss rates, in healthy controls (HCs) and in patients with relapsing MS (RMS) treated with ocrelizumab, which suppresses acute inflammation. METHODS: Whole brain, white matter, cortical gray matter, thalamic, and cerebellar volume loss rates were assessed in 44 HCs that were part of a substudy in the OPERA II randomized controlled trial (NCT01412333) and 59 patients with RMS enrolled in the same substudy as well as age- and sex-matched patients in OPERA I (NCT01247324) and II. Volume loss rates were computed using random coefficients models over a period of 2 years. RESULTS: Ocrelizumab-treated patients showed global and regional brain volume loss rates that were approaching that of HCs. CONCLUSION: These findings are consistent with an important role of inflammation on overall tissue loss and the role of ocrelizumab in reducing this phenomenon.

Key Factors in Decision Making for ECLS: A Binational Factorial Survey.

BACKGROUND: Extracorporeal life support (ECLS) provides support to patients with cardiopulmonary failure refractory to conventional therapy. While ECLS is potentially life-saving, it is associated with severe complications; decision making to initiate ECLS must, therefore, carefully consider which patients ECLS potentially benefits despite its consequences. OBJECTIVE: To answer 2 questions: First, which medically relevant patient factors influence decisions to initiate ECLS? Second, what are factors relevant to decisions to withdraw a running ECLS treatment? METHODS: We conducted a factorial survey among 420 physicians from 111 hospitals in Switzerland and Germany. The study included 2 scenarios: 1 explored willingness to initiate ECLS, and 1 explored willingness to withdraw a running ECLS treatment. Each participant responded to 5 different vignettes for each scenario. Vignettes were analyzed using mixed-effects regression models with random intercepts. RESULTS: Factors in the vignettes such as patients' age, treatment costs, therapeutic goal, comorbidities, and neurological outcome significantly influenced the decision to initiate ECLS. When it came to the decision to withdraw ECLS, patients' age, days on ECLS, criteria for discontinuation, condition of the patient, comorbidities, and neurological outcome were significant factors. In both scenarios, patients' age and neurological outcome were the most influential factors. CONCLUSIONS: This study provided insights into physicians' decision making processes about ECLS initiation and withdrawal. Patients' age and neurological status were the strongest factors influencing decisions regarding initiation of ECLS as well as for ECLS withdrawal. The findings may contribute to a more refined understanding of complex decision making for ECLS.

NRS-2002 components, nutritional score and severity of disease score, and their association with hospital length of stay and mortality.

BACKGROUND: Malnutrition is a substantial issue in hospitals, leading to prolonged length of hospital stay, increased perioperative morbidity and increased mortality. There are several validated screening tools for malnutrition, one of which is the Nutritional Risk Screening 2002 (NRS). It screens patients based on recent weight loss, reduction of recent food intake, body mass index (BMI), severity of disease and age. Higher NRS scores have been shown to be negatively associated with patients’ outcomes such as increased morbidity and mortality. OBJECTIVES: The aim of the study was to evaluate how the two NRS components Nutritional Score (NS) and Severity of Disease Score (SDS) are associated with patients’ length of hospital stay and mortality. METHODS: All patients admitted to the medical department of a large community hospital in Switzerland were screened for malnutrition using the nutrition screening NRS during the years 2014 to 2017. Data on patients’ NRS, primary diagnosis, number of secondary diagnoses, mortality, length of stay (LOS), discharge, sex and age were collected. The association between the NRS components and LOS/mortality was estimated using a linear mixed-effects regression model and a logistic regression model, respectively, with adjustment for confounders (age, sex, comorbidity, diagnosis group, mode of discharge and year of hospitalisation). RESULTS: The evaluation of the outcomes of 21,855 hospitalisations demonstrated that the NS was associated with an increment in the LOS of 5.5–12.3% per score point, depending on the diagnosis group. An increase in the SDS by one point was associated with an increase in the LOS of 2.2–11.3%. The odds for all-cause in-hospital mortality were increased by 44.1% (95% confidence interval [CI] 33.7–55.2%) per point in the NS, and by 73% (95% CI 57.5–90.1%) per point in the SDS. CONCLUSIONS: Increases in both components of the NRS are associated with longer LOS. The NS has a slightly stronger impact on LOS compared to the SDS and its effect is dependent on the patient’s diagnosis group. Increases in the SDS are linked to a higher mortality than increases in the NS.

Safety and efficacy of balloon angioplasty in symptomatic intracranial stenosis: A systematic review and meta-analysis.

BACKGROUND AND PURPOSE: Endovascular treatment is offered for symptomatic intracranial stenosis (ICS) when medical therapy fails. The purpose of this meta-analysis is to evaluate the risks and effectiveness of balloon angioplasty (BA) alone. MATERIALS AND METHODS: Systematic review and meta-analysis of all available articles on BA for symptomatic ICS was conducted. Data was analyzed separately for > 70% (Group 1) and > 50% (Group 2) stenosis. The results of the Group 1 were compared with those of SAMMPRIS study to the extent possible. RESULTS: A total of 25 studies comprising 674 patients were included. The cumulative incidence of periprocedural (within 30 days) stroke and death were 16.3% (Group 1), 7.6% (Group 2) and 11.5% (all studies). Incidence rates of ischemic stroke in the qualifying artery territory during follow-up (per 100 patient-years) were 2.0, 2.4 and 2.3, any stroke and death during follow-up were 4.4, 7.4 and 6.9, restenosis rates were 4.9, 11.5 and 8.9 respectively. While comparison of cumulative incidences of periprocedural ischemic stroke between Group 1 (13.0%) and the medical arm from SAMMPRIS study(4.4%) showed a significant difference (P = 0.008), there was no significant difference between the Group 1 and the stenting arm from SAMMPRIS study(10.7%) in the same variable. CONCLUSION: Balloon angioplasty for stenosis of more than 70% is likely to have similar outcome comparable to the stenting arm in the SAMMPRIS study, however it presents lower rates of late ischemic events and restenosis. These data may help deciding on the endovascular method of choice in case of medical therapy failure.

Physical activity and screen time in children who survived cancer: A report from the Swiss Childhood Cancer Survivor Study.

BACKGROUND: Physical activity (PA) can reduce the risk of chronic adverse health conditions in childhood cancer survivors. We examined PA and sedentary screen time behavior in a nationwide study in Switzerland. PROCEDURES: The Swiss Childhood Cancer Survivor Study sent questionnaires to parents of all Swiss resident ≥5-year survivors diagnosed between 1995 and 2010. We assessed PA including compulsory school sport, recreational sport, commuting to school, and time spent with screen media in those aged 5-15 years, and compared results with international recommendations. RESULTS: We included 766 survivors with a median age at diagnosis of 2.8 (interquartile range 1.4-5.0) years and a median age at study of 12.5 (10.0-14.3) years. Median PA time was 7.3 (4.8-10.0) h/week and median screen time was 82 (45-120) min/day. Compulsory school sport hours and walking or cycling to school contributed significantly to total PA. Note that 55% of survivors met PA and 68% screen time recommendations. PA was lower for children living in regions of Switzerland speaking French or Italian compared to German, and for those who had a relapse or musculoskeletal/neurological conditions. Screen time was higher in males, children with lower parental education, and a migration background. CONCLUSIONS: PA and sedentary screen watching were associated with social factors, and PA also with clinical risk factors. Structural preventions that afford active commuting to school and sufficient school sport are essential, as is counseling vulnerable survivor groups such as those with musculoskeletal and neurological problems, and those who have had a relapse.

The Spinal Transcriptome after Cortical Stroke: In Search of Molecular Factors Regulating Spontaneous Recovery in the Spinal Cord.

In response to cortical stroke and unilateral corticospinal tract degeneration, compensatory sprouting of spared corticospinal fibers is associated with recovery of skilled movement in rodents. To date, little is known about the molecular mechanisms orchestrating this spontaneous rewiring. In this study, we provide insights into the molecular changes in the spinal cord tissue after large ischemic cortical injury in adult female mice, with a focus on factors that might influence the reinnervation process by contralesional corticospinal neurons. We mapped the area of cervical gray matter reinnervation by sprouting contralesional corticospinal axons after unilateral photothrombotic stroke of the motor cortex in mice using anterograde tracing. The mRNA profile of this reinnervation area was analyzed using whole-genome sequencing to identify differentially expressed genes at selected time points during the recovery process. Bioinformatic analysis revealed two phases of processes: early after stroke (4-7 d post-injury), the spinal transcriptome is characterized by inflammatory processes, including phagocytic processes as well as complement cascade activation. Microglia are specifically activated in the denervated corticospinal projection fields in this early phase. In a later phase (28-42 d post-injury), biological processes include tissue repair pathways with upregulated genes related to neurite outgrowth. Thus, the stroke-denervated spinal gray matter, in particular its intermediate laminae, represents a growth-promoting environment for sprouting corticospinal fibers originating from the contralesional motor cortex. This dataset provides a solid starting point for future studies addressing key elements of the post-stroke recovery process, with the goal to improve neuroregenerative treatment options for stroke patients.SIGNIFICANCE STATEMENT We show that the molecular changes in the spinal cord target tissue of the stroke-affected corticospinal tract are mainly defined by two phases: an early inflammatory phase during which microglia are specifically activated in the target area of reinnervating corticospinal motor neurons; and a late phase during which growth-promoting factors are upregulated which can influence the sprouting response, arborization, and synapse formation. By defining for the first time the endogenous molecular machinery in the stroke-denervated cervical spinal gray matter with a focus on promotors of axon growth through the growth-inhibitory adult CNS, this study will serve as a basis to address novel neuroregenerative treatment options for chronic stroke patients.

Safety and immunogenicity of tetanus/diphtheria vaccination in patients with rheumatic diseases-a prospective multi-centre cohort study.

OBJECTIVES: We aimed to assess the safety and immunogenicity of a diphtheria/tetanus vaccine booster dose in three different patient groups with rheumatic diseases on a variety of immunosuppressive/immunomodulatory medications compared with healthy controls (HCs). METHODS: We conducted a multi-centre prospective cohort study in Switzerland. We enrolled patients with RA, axial SpA/PsA, vasculitis (Behçet's disease, ANCA-associated vasculitis) and HCs. Diphtheria/tetanus vaccination was administered according to the Swiss vaccination recommendations. Blood samples were drawn before vaccination, and 1 month and 3 months afterwards. Antibody concentrations against vaccine antigens were measured by ELISA. Immunogenicity was compared between patient and medication groups. A mixed model was applied for multivariate analysis. Missing data were dealt with using multiple imputation. RESULTS: Between January 2014 and December 2015, we enrolled 284 patients with rheumatic diseases (131 RA, 114 SpA/PsA, 39 vasculitis) and 253 HCs. Of the patients, 89% were on immunosuppressive/immunomodulatory medication. Three months post-vaccination 100% of HCs vs 98% of patients were protected against tetanus and 84% vs 73% against diphtheria. HCs and SpA/PsA patients had significantly higher responses than RA and vasculitis patients. Assessing underlying diseases and medications in a multivariate model, rituximab was the only factor negatively influencing tetanus immunogenicity, whereas only MTX treatment had a negative influence on diphtheria antibody responses. No vaccine-related serious adverse events were recorded. CONCLUSION: Diphtheria/tetanus booster vaccination was safe. Tetanus vaccination was immunogenic; the diphtheria component was less immunogenic. Vaccine responses were blunted by rituximab and MTX.

Disturbed sphingolipid metabolism with elevated 1-deoxysphingolipids in glycogen storage disease type I - A link to metabolic control.

BACKGROUND: 1-Deoxysphingolipids (1-deoxySLs) are atypical sphingolipids. They are formed during sphingolipid de novo synthesis by the enzyme serine palmitoyltransferase, due to the alternate use of alanine over its canonical substrate serine. Pathologically elevated 1-deoxySL are involved in several neurological and metabolic disorders. The objective of this study was to investigate the role of 1-deoxySL in glycogen storage disease type I (GSDI). METHODS: In this prospective, longitudinal observational study (median follow-up 1.8y), the plasma 1-deoxySL profile was analyzed in 15 adult GSDI patients (12 GSDIa, 3 GSDIb), and 31 healthy controls, along with standard parameters for monitoring GSDI. RESULTS: 1-Deoxysphinganine (1-deoxySA) concentrations were elevated in GSDI compared to controls (191 ±â€¯129 vs 35 ±â€¯14 nmol/l, p < 0.0001). Concordant with the mechanism of 1-deoxySL synthesis, plasma alanine was higher (625 ±â€¯182 vs 398 ±â€¯90 µmol/l, p < 0.0001), while serine was lower in GSDI than in controls (88 ±â€¯22 vs 110 ±â€¯18 µmol/l. p < 0.001). Accordingly, serine, alanine and triglycerides were determinants of 1-deoxySA in the longitudinal analysis of GSDIa. 1-deoxySA concentrations correlated with the occurrence of low blood glucose (area under the curve below 4 mmol/l) in continuous glucose monitoring. The 1-deoxySL profile in GSDIb was distinct from GSDIa, with a different ratio of saturated to unsaturated 1-deoxySL. CONCLUSION: In addition to the known abnormalities of lipoproteins, GSDI patients also have a disturbed sphingolipid metabolism with elevated plasma 1-deoxySL concentrations. 1-DeoxySA relates to the occurrence of low blood glucose, and may constitute a potential new biomarker for assessing metabolic control. GSDIa and Ib have distinct 1-deoxySL profiles indicating that both GSD subtypes have diverse phenotypes regarding lipid metabolism.

Pericardial effusion unrelated to surgery is a predictor of mortality in heart transplant patients.

BACKGROUND: Hemodynamically irrelevant pericardial effusion (PeEf) is a predictor of adverse outcome in heart failure patients. The clinical relevance of a PeEf unrelated to surgery in heart transplant patients remains unknown. This study assesses the prognostic value of PeEf occurring later than 1 year after transplantation. METHODS: All patients undergoing heart transplantation in Zurich between 1989 and 2012 were screened. Cox proportional hazard models were used to analyze mortality (primary) and hospitalization (secondary endpoint). PeEf time points were compared to baseline for rejection, immunosuppressants, tumors, inflam-mation, heart failure, kidney function, hemodynamic, and echocardiographic parameters. RESULTS: Of 152 patients (mean age 48.3 ± 11.9), 25 developed PeEf. Median follow-up period was 11.9 (IQR 5.8-17) years. The number of deaths was 6 in the PeEf group and 46 in the non-PeEf group. The occurrence of PeEf was associated with a 2.5-fold increased risk of death (HR 2.49, 95% CI 1.02-6.13, p = 0.046) and hospitalization (HR 2.53, 95% CI 1.57-4.1, p = 0.0002). CONCLUSIONS: This study reveals that the finding of hemodynamically irrelevant PeEf in heart trans-plant patients is a predictor of adverse outcome, suggesting that a careful clinical assessment is war-ranted in heart transplant patients exhibiting small PeEf.

Outer Retinal Dysfunction in the Absence of Structural Abnormalities in Multiple Sclerosis.

Purpose: Recent evidence suggests structural changes distal to the inner retina in multiple sclerosis (MS) patients. The functional correlates of these proposed structural abnormalities remain unclear. We investigated outer retinal function and structure in MS patients, and quantified to what extent outer retinal structure influenced function in these patients. Methods: Outer retinal function was assessed using the full-field and multifocal electroretinogram (ERG/MF-ERG), whereas retinal structure was assessed using spectral-domain optical coherence tomography (OCT). Results were compared with preexisting normative data. The relationships between electrophysiology parameters and the OCT values corresponding to the proposed cellular origins of the ERG and MF-ERG were analyzed. Results: Most electrophysiological responses were delayed in MS patients, independently of optic neuritis (ON). Inner retinal thickness and volumes were reduced, and inner nuclear layer volume marginally increased, in eyes with previous ON; all other OCT parameters were normal. OCT results correlated with ERG amplitudes, but not with ERG peak times or any MF-ERG parameters. Conclusions: We recorded outer retinal dysfunction without detectable abnormalities of the corresponding retinal layers in MS patients, not ascribable to retrograde degeneration following ON. The findings complement a growing body of literature reporting primary retinal abnormalities distal to the ganglion cell-inner plexiform layer complex in MS patients, with our data suggesting that this may be a more widespread phenomenon than previously thought. ERG may be of more utility in detecting retinal dysfunction in MS patients than MF-ERG. Analysis of peak times, rather than response amplitudes, is recommended.

High EDSS can predict risk for upper urinary tract damage in patients with multiple sclerosis.

BACKGROUND: Neurogenic lower urinary tract dysfunction (NLUTD) is very common in patients with multiple sclerosis (MS), and it might jeopardize renal function and thereby increase mortality. Although there are well-known urodynamic risk factors for upper urinary tract damage, no clinical prediction parameters are available. OBJECTIVE: We aimed to assess clinical parameters potentially predicting urodynamic risk factors for upper urinary tract damage. METHODS: A consecutive series of 141 patients with MS referred from neurologists for primary neuro-urological work-up including urodynamics were prospectively evaluated. Clinical parameters taken into account were age, sex, duration, and clinical course of MS and Expanded Disability Status Scale (EDSS). RESULTS: Multivariate modeling revealed EDSS as a clinical parameter significantly associated with urodynamic risk factors for upper urinary tract damage (odds ratio = 1.34, 95% confidence interval (CI) = 1.06-1.71, p = 0.02). Using receiver operator characteristic (ROC) curves, an EDSS of 5.0 as cutoff showed a sensitivity of 86%-87% and a specificity of 52% for at least one urodynamic risk factor for upper urinary tract damage. CONCLUSION: High EDSS is significantly associated with urodynamic risk factors for upper urinary tract damage and allows a risk-dependent stratification in daily neurological clinical practice to identify MS patients requiring further neuro-urological assessment and treatment.

Feasibility of reusing time-matched controls in an overlapping cohort.

The methods developed for secondary analysis of nested case-control data have been illustrated only in simplified settings in a common cohort and have not found their way into biostatistical practice. This paper demonstrates the feasibility of reusing prior nested case-control data in a realistic setting where a new outcome is available in an overlapping cohort where no new controls were gathered and where all data have been anonymised. Using basic information about the background cohort and sampling criteria, the new cases and prior data are "aligned" to identify the common underlying study base. With this study base, a Kaplan-Meier table of the prior outcome extracts the risk sets required to calculate the weights to assign to the controls to remove the sampling bias. A weighted Cox regression, implemented in standard statistical software, provides unbiased hazard ratios. Using the method to compare cases of contralateral breast cancer to available controls from a prior study of metastases, we identified a multifocal tumor as a risk factor that has not been reported previously. We examine the sensitivity of the method to an imperfect weighting scheme and discuss its merits and pitfalls to provide guidance for its use in medical research studies.

Evaluation of a multiprofessional, nonsurgical obesity treatment program: which parameters indicated life style changes and weight loss?

BACKGROUND: According to the current evidence, behavior modifications are an effective part of a non-surgical multiprofessional obesity treatment program (MOTP). The purpose of the present study was to report changes in weight as well in psychological variables during a one year MOTP. We aimed to identify the associations of emotional state and patients' emotion regulation skills with weight change. METHODS: Prospective interventional study. Data of participants attending the one year obesity treatment in either a group or individual structured MOTP were analyzed. Weight, BMI (Body Mass Index) and measures on psychosomatic variables, emotion regulation skills, affective state, shame and guilt were collected at baseline, after three months and after one year. Mixed-effects models were used for the statistical analysis of BMI. RESULTS: We included 238 patients at baseline (t1), 234 after three months (t2) and 179 after one year (t3). A drop in BMI measurements of at least 5% was observed in 20.6% of participants at t2 and 41.4% of participants at t3. After three months, participants showed significant improvements in the following psychosomatic variables: somatisation (p < 0.001), interpersonal sensitivity (p < 0.001), emotion regulation skills (p < 0.01), and attention to emotions (p < 0.05). Most of the improvements could be maintained after one year. BMI reduction was associated with a positive change in emotions, improvements in emotion regulation skills, and a reduction of depressive symptoms, disgust and shame. CONCLUSIONS: The results indicate that the assessment and treatment of psychological aspects like depression, emotion regulation skills, body awareness, and acceptance should be a vital part of an interdisciplinary MOPT. TRIAL REGISTRATION: Ethical approval for the present study was obtained from the Bern Kantonal Ethics Committee (KEK-Bern-Study Nr 258/14), Bern, Switzerland.

Prognostic power of NT-proBNP in left ventricular non-compaction cardiomyopathy.

BACKGROUND: The risk of adverse events in patients with left ventricular non-compaction cardiomyopathy (LVNC) is substantial. This study was designed to determine the prognostic value of NT-proBNP, left ventricular ejection fraction (LVEF), NYHA class, and exercise capacity in LVNC patients. METHODS: Cox regression analyses were performed for evaluating the prognostic value of NT-proBNP, LVEF, NYHA class, and exercise capacity on the occurrence of death or heart transplantation. 153 patients were included. RESULTS: During 1013 person-years (longest follow-up 18.5years) 23 patients (15%) died or underwent heart transplantation. We observed a significant relationship of NT-proBNP (adjusted HR 2.44, 95% CI 1.45-4.09, for every NT-proBNP doubling, p=0.0007) and LVEF (adjusted HR for age 60years: 2.68, 95% CI 1.62-4.41, p=0.0001) with the risk of death or heart transplantation. Combined covariate analysis indicated a strong influence of NT-proBNP (adjusted 2.89, 95% CI 1.33-6.26, p=0.007), whereas LVEF was no longer significant (adjusted HR 0.82, 95% CI 0.42-1.67, p=0.66) demonstrating a favorable prognostic power of NT-proBNP over LVEF. An increase in NYHA class was associated with a worse outcome, and exercise capacity revealed a trend in the same direction. For all the abovementioned analyses, similar results were obtained when assessing the values at first presentation. CONCLUSION: This study provides evidence that an increase in NT-proBNP is a strong predictor of outcome in patients with LVNC. The prognostic power of NT-proBNP is at least as good as that of LVEF, indicating that routine NT-proBNP measurement may improve risk assessment in LVNC.

Breastfeeding in Women Having Experienced Childhood Sexual Abuse.

BACKGROUND: Childhood sexual abuse (CSA) can have a serious effect on general and obstetric health. Breastfeeding includes several triggers for memories of abuse experiences, which will likely influence decisions about breastfeeding and its implementation in daily life. This is important since breastfeeding improves maternal well-being and bonding with the child. Research aim: As breastfeeding strongly influences the long-term health of children, we investigated experiences with breastfeeding in women with a history of CSA. METHODS: Data on breastfeeding were collected within a research project designed to compare labor and delivery experiences in women with a history of CSA to women without such antecedents. Data from 85 women having experienced CSA and 170 controls pair-matched for maternal age, children's age, and nationality were evaluated. The clinical record of pregnancy and a self-administered questionnaire were used to collect data. RESULTS: Although the prevalence of breastfeeding was similar in women with and without CSA experiences (96.5% vs. 90.6%), women exposed to CSA more often described complications associated with breastfeeding (77.7% vs. 67.1%, p = .08). Mastitis (49.4% vs. 27.6%, p < .01) and pain (29.4% vs. 18.8%, p = .15) were reported significantly more often by women after CSA. For 20% of women after CSA, breastfeeding was a trigger for memories of CSA. Furthermore, 58% of women with CSA reported dissociation when breastfeeding. CONCLUSION: In addition to the growing list of potential health consequences of CSA experience, this experience seems to be associated with an increased number of problems when breastfeeding. However, most women with a history of CSA intend to breastfeed despite particular challenges related to CSA. A support protocol tailored to the specific needs of these women during pregnancy and the lactation period may help to improve breastfeeding and the early mother-child relationship.

Cerebral Microembolization During Aortic Valve Replacement Using Minimally Invasive or Conventional Extracorporeal Circulation: A Randomized Trial.

To compare intraoperative cerebral microembolic load between minimally invasive extracorporeal circulation (MiECC) and conventional extracorporeal circulation (CECC) during isolated surgical aortic valve replacement (SAVR), we conducted a randomized trial in patients undergoing primary elective SAVR at a tertiary referral hospital. The primary outcome was the procedural phase-related rate of high-intensity transient signals (HITS) on transcranial Doppler ultrasound. HITS rate was used as a surrogate of cerebral microembolism in pre-defined procedural phases in SAVR using MiECC or CECC with (+F) or without (-F) an oxygenator with integrated arterial filter. Forty-eight patients were randomized in a 1:1 ratio to MiECC or CECC. Due to intraprocedural Doppler signal loss (n = 3), 45 patients were included in final analysis. MiECC perfusion regimen showed a significantly increased HITS rate compared to CECC (by a factor of 1.75; 95% confidence interval, 1.19-2.56). This was due to different HITS rates in procedural phases from aortic cross-clamping until declamping [phase 4] (P = 0.01), and from aortic declamping until stop of extracorporeal perfusion [phase 5] (P = 0.05). Post hoc analysis revealed that MiECC-F generated a higher HITS rate than CECC+F (P = 0.005), CECC-F (P = 0.05) in phase 4, and CECC-F (P = 0.03) in phase 5, respectively. In open-heart surgery, MiECC is not superior to CECC with regard to gaseous cerebral microembolism. When using MiECC for SAVR, the use of oxygenators with integrated arterial line filter appears highly advisable. Only with this precaution, MiECC confers a cerebral microembolic load comparable to CECC during this type of open heart surgery.

Adopting a family approach to theory and practice: measuring distress in cancer patient-partner dyads with the distress thermometer.

OBJECTIVE: Significant others are central to patients' experience and management of their cancer illness. Building on our validation of the Distress Thermometer (DT) for family members, this investigation examines individual and collective distress in a sample of cancer patients and their matched partners, accounting for the aspects of gender and role. METHOD: Questionnaires including the DT were completed by a heterogeneous sample of 224 couples taking part in a multisite study. RESULTS: Our investigation showed that male patients (34.2%), female patients (31.9%), and male partners (29.1%) exhibited very similar levels of distress, while female partners (50.5%) exhibited much higher levels of distress according to the DT. At the dyad level just over half the total sample contained at least one individual reporting significant levels of distress. Among dyads with at least one distressed person, the proportion of dyads where both individuals reported distress was greatest (23.6%). Gender and role analyses revealed that males and females were not equally distributed among the four categories of dyads (i.e. dyads with no distress; dyads where solely the patient or dyads where solely the partner is distressed; dyads where both are distressed). CONCLUSION: A remarkable number of dyads reported distress in one or both partners. Diverse patterns of distress within dyads suggest varying risks of psychosocial strain. Screening patients' partners in addition to patients themselves may enable earlier identification of risk settings. The support offered to either member of such dyads should account for their role- and gender-specific needs.
