Psychological characteristics and physiological reactivity to acute stress in mothers of children with autism spectrum disorder

Stress related to parenting a child with autism spectrum disorder can differently affect caregiver's physiological reactivity to acute stress. Here, parental stress levels, psychological characteristics, and coping strategies were assessed alongside measures of heart rate, heart rate variability, and cortisol during a psychosocial stress test in mothers of children with ASD (M‐ASD, n = 15) and mothers of typically developing children (n = 15). M‐ASD reported significantly higher levels of parental stress, anxiety, negative affectivity, social inhibition, and a larger preference for avoidance strategies. M‐ASD showed larger heart rate and cortisol responses to the psychosocial stress test. A positive relationship was found between parental stress levels and the magnitude of the cortisol stress response in both groups. The present findings indicate exaggerated physiological reactivity to acute psychosocial stress in M‐ASD and prompt further research to explore the role of individual differences in mediating the effects of parental stress on physiological stress responses.     

Prior Exposure to Interpersonal Violence and Long‐Term Treatment Response for Boys With a Disruptive Behavior Disorder

Interpersonal violence (IPV) is common in children with a disruptive behavior disorder (DBD) and increases the risk for greater DBD symptom severity, callous–unemotional (CU) traits, and neuroendocrine disruption. Thus, IPV may make it difficult to change symptom trajectories for families receiving DBD interventions given these relationships. The current study examined whether IPV prior to receiving treatment for a DBD predicted trajectories of a variety of associated outcomes, specifically DBD symptoms, CU traits, and cortisol concentrations. Boys with a DBD diagnosis (N = 66; age range = 6–11 years; 54.5% of whom experienced IPV prior to treatment) of either oppositional defiant disorder or conduct disorder participated in a randomized clinical trial and were assessed 3 years following treatment. Multilevel modeling demonstrated that prior IPV predicted smaller rates of change in DBD symptoms, CU traits, and cortisol trajectories, indicating less benefit from intervention. The effect size magnitudes of IPV were large for each outcome (d = 0.88–1.07). These results suggest that IPV is a predictor of the long‐term treatment response for boys with a DBD. Including trauma‐focused components into existing DBD interventions may be worth testing to improve treatment effectiveness for boys with a prior history of IPV.     

Adverse childhood experiences and neuroinflammatory biomarkers—The role of sex

Despite the growing interest in adverse childhood experiences and biomarkers, less attention has been paid to multiple biomarkers as representing interrelated systems among college students. Guided by the neuroinflammatory pathway hypothesis, the current project takes the initial step in examining the link between three types of childhood adversity and biomarkers of neuroplasticity (brain‐derived neurotropic factor [BDNF]) and low‐grade inflammation (C‐reactive protein [CRP]) in an overarching model and whether this link may differ in men and women. Undergraduate students (n = 85) were recruited through multiple departments from a state university. The participants responded to the detailed online survey questionnaire on childhood adversity and provided one blood sample via venous blood draw. Given that CRP and BDNF represent two interrelated systems, structural equation models were considered the most suitable for the analyses. The findings partially support neural and inflammatory pathways, such that childhood adversity and particularly family dysfunction have a significant positive effect on BDNF (b = 30.41, p < .01). The link between family dysfunction and CRP was stronger in female students (b = 0.57, p < .05). Results suggest that interventions for college students with family dysfunctions may need to target different physiological and behavioral outcomes for male and female students.     

Combining walking and relaxation for stress reduction—A randomized cross‐over trial in healthy adults

Both physical activity and relaxation have stress‐relieving potential. This study investigates their combined impact on the relaxation response while considering participants' initial stress level. In a randomized cross‐over trial, 81 healthy adults completed 4 types of short‐term interventions for stress reduction, each lasting for 1 hr: (1) physical activity (walking) combined with resting, (2) walking combined with balneotherapy, (3) combined resting and balneotherapy, and (4) resting only. Saliva cortisol, blood pressure, state of mood, and relaxation were measured preintervention and postintervention. Stress levels were determined by validated questionnaires. All interventions were associated with relaxation responses in the variables saliva cortisol, blood pressure, state of mood, and subjective relaxation. No significant differences were found regarding the reduction of salivary cortisol (F = 1.30; p = .281). The systolic blood pressure was reduced best when walking was combined with balneotherapy or resting (F = 7.34; p < .001). Participants with high stress levels (n = 25) felt more alert after interventions including balneotherapy, whereas they reported an increase of tiredness when walking was combined with resting (F = 3.20; p = .044). Results suggest that combining physical activity and relaxation (resting or balneotherapy) is an advantageous short‐term strategy for stress reduction as systolic blood pressure is reduced best while similar levels of relaxation can be obtained.     

School‐Based Psychological Screening in the Aftermath of a Disaster: Are Parents Satisfied and Do Their Children Access Treatment?

This study investigated parents’ satisfaction with postdisaster school‐based screening and whether satisfaction was related to follow‐through with screening recommendations. From among 1,268 there were 224 children, ages 7–18 years (M = 10.97, SD = 2.44 years) screened for emotional distress 4 months after a flood and 130 parents who completed the screening evaluation. Of the 44 children who showed severe emotional distress, less than 50% of their parents reported concerns and only 29.5% had sought assistance. Following screening, 86.7% of these children completed treatment. Overall satisfaction ratings by parents were high, with 99.2% very or mostly satisfied.     

Posttraumatic Stress Symptoms in Preschool Children in Foster Care: The Influence of Placement and Foster Family Environment

Children in foster care often experience traumatic events which increase their risk for posttraumatic stress symptoms (PTSS). Until now, no research has investigated the developmentally sensitive PTSS criteria for preschoolers among children in foster care. The current study estimated the prevalence of potentially traumatic experiences and clinical PTSS in German foster care children aged 3 to 7 years. The foster parents of 324 children completed questionnaires about children's PTSS, foster parental stress, parenting, and family functioning. Linear regression models tested trauma‐related variables, placement history, and foster family characteristics as predictors of PTSS. Approximately 45.4% of the foster children had experienced at least one traumatic event and 15.4% had clinical PTSS. Physical abuse, β = .34, p  < .001; hospitalization, β = −.17, p = .026; witnessing someone being hurt, β = −.15, p = .047; and parental stress, β = .43, p  < .001, were significantly associated with PTSS. Results demonstrate the impact the foster family has on children who are coping with trauma, and suggest the necessity of trauma‐sensitive trainings for foster parents, with stress management as an important component.     

Structural validity of the Parenting Daily Hassles Intensity Scale

Although the Parenting Daily Hassles Intensity Scale is a common measure, it has been relatively unclear whether users should employ the 15‐item form that quantifies routine parenting hassles on two dimensions of intensity or the 20‐item form that assumes a single dimension underlies the responses on the scale. To help address this gap, Bayesian confirmatory factor analysis was used to investigate the structural validity of the 15‐ and 20‐item forms in a sample of 174 mothers with at least one young child (  = 6.040, SD = 0.492). Results of the Bayesian analysis did not provide empirical support for either form. A subsequent exploratory factor analysis indicated that six of the hassles that appear to address challenging child behaviour tended to cluster onto one latent factor whereas 11 hassles that appear to speak to routine parenting chores tended to cluster onto a second factor. A follow‐up Bayesian analysis indicated that intensity scores can be approximated well under the 17‐item form (ppp = 0.124). Accordingly, researchers and clinicians are encouraged to consider the 17‐item form when addressing their measurement needs.     

Probable Posttraumatic Stress Disorder and Women's Use of Aggression in Intimate Relationships: The Moderating Role of Alcohol Dependence

Posttraumatic stress disorder (PTSD) is highly prevalent among individuals who experience intimate partner violence (IPV) and is associated with aggression in intimate relationships. The present study examined whether alcohol dependence (AD) attenuates the relation between PTSD and IPV‐victimized women's use of physical, psychological, and sexual aggression. Participants were recruited from the community and included 147 women who engaged in substance use and experienced IPV (80.3% Black; M age = 38.24 years, SD = 10.62; M income = $14,323, SD = $12,832). Women with (vs. without) AD reported using significantly more physical and psychological aggression (η_p² = .12 and .03, respectively). The probable PTSD × AD interaction emerged as a significant correlate of physical and sexual aggression (η_p² = .03). Post hoc analyses revealed higher levels of physical aggression among women with probable PTSD and AD and no‐PTSD and AD compared to women with probable PTSD and no‐AD (Cohen's ds = 1.09 and 0.63, respectively) and women without PTSD and no‐AD (Cohen's ds = 0.92 and 0.60, respectively). Further, women with PTSD and AD reported higher levels of sexual aggression than women without PTSD and AD (Cohen's d = 0.80). Findings suggest the utility of identifying and treating PTSD‐AD among IPV‐victimized women.     

Changes and predictors of psychological stress among elderly stroke survivors 6 months after hospital discharge

The aim of this study was to analyse the changes in psychological stress and identify its basal predictors among elderly stroke survivors after 6 months following discharge from hospital to home directly, rather than to a rehabilitation facility. The sample comprised 50 elderly stroke survivors. Data were collected at 2 weeks (T1), at 3 months (T2), and at 6 months (T3) after hospital discharge. The following instruments were applied: Perceived Stress Scale—10 items (PSS‐10), National Institute of Health Stroke Scale, Functional Independence Measure, and Geriatric Depression Scale—15 items. Study records indicated that the age of the study participants ranged from 60 to 87 years old (mean = 70.3; standard deviation = 7.6). The number of male and female participants was similar. The PSS‐10 score decreased almost 6 points between T1 (mean = 15.1) and T3 (mean = 9.7; p < .001). Both Functional Independence Measure (p = .025) and Geriatric Depression Scale‐15 (p = .017) scores at T1 predicted the PSS‐10 score at T3. The study thus demonstrated that elderly stroke survivors experienced significant stress after hospital discharge, which tended to improve over the next 6 months. Depression and lower functional independence 2 weeks after discharge were predictors of a greater level of psychological stress at 6 months following discharge.     

Posttransplant muscle mass measured by urinary creatinine excretion rate predicts long‐term outcomes after liver transplantation

Long‐term survival in orthotopic liver transplant (OLT) recipients remains impaired because of many contributing factors, including a low pretransplant muscle mass (or sarcopenia). However, influence of posttransplant muscle mass on survival is currently unknown. We hypothesized that posttransplant urinary creatinine excretion rate (CER), an established noninvasive marker of total body muscle mass, is associated with long‐term survival after OLT. In a single‐center cohort study of 382 adult OLT recipients, mean ± standard deviation CER at 1 year posttransplantation was 13.3 ± 3.7 mmol/24 h in men and 9.4 ± 2.6 mmol/24 h in women. During median follow‐up for 9.8 y (interquartile range 6.4‐15.0 y), 104 (27.2%) OLT recipients died and 44 (11.5%) developed graft failure. In Cox regression analyses, as continuous variable, low CER was associated with increased risk for mortality (HR = 0.43, 95% CI: 0.26‐0.71, P = .001) and graft failure (HR = 0.42, 95% CI: 0.20‐0.90, P = .03), independent of age, sex, and body surface area. Similarly, OLT recipients in the lowest tertile had an increased risk for mortality (HR = 2.69; 95% CI: 1.47‐4.91, P = .001) and graft failure (HR = 2.77, 95% CI: 1.04‐7.39, P = .04), compared to OLT recipients in the highest tertile. We conclude that 1 year posttransplant low total body muscle mass is associated with long‐term risk of mortality and graft failure in OLT recipients.     

Stress system dysregulation in pediatric generalized anxiety disorder associated with comorbid depression

Because chronic stress is an important risk factor for anxiety states and depressive disorders, we studied hypothalamus–pituitary–adrenal (HPA) axis and sympathetic system activity via changes in cortisol and alpha amylase activity levels in pediatric generalized anxiety disorder (GAD) patients (n = 26) with comorbid depression and a healthy comparison group (n = 26). Morning plasma cortisol and diurnal profiles of salivary cortisol and salivary alpha amylase (sAA) activity were assessed, also reactivity of HPA‐axis, sAA activity, and heart rate following a psychosocial stressor (Trier Social Stress Test for children). GAD patients with comorbid depression showed increased morning plasma and salivary cortisol levels, ameliorating throughout in‐patient treatment, and higher sAA activity in their diurnal profile. Both HPA and sympathetic activity positively correlated with the severity of anxiety and depression. We also demonstrated a blunted HPA and sympathetic response to acute stress in patients. This pattern of neuroendocrine and sympathetic changes seems to be distinct from the one previously reported in pediatric patients with only social anxiety or depressive disorders. We propose morning plasma and saliva cortisol levels as potential physiological indicators for supporting the evaluation of symptoms' severity and treatment progress in children with GAD and comorbid depressive disorder.     

Resilience dimensions and mental health outcomes in bipolar disorder in a follow‐up study

The individual process of resilience has been related to positive outcomes in mental disorders. We aimed (a) to identify the resilience domains from the Resilience Questionnaire for Bipolar Disorder that are associated cross sectionally and longitudinally with mental health outcomes in bipolar disorder (BD) and (b) to explore cross‐lagged associations among resilience factors. A clinical adult sample of 125 patients diagnosed with BD (62.10% female, mean age = 46.13, SD = 10.89) gave their informed consent and completed a battery of disease‐specific tools on resilience, personal recovery, symptomatology, psychosocial functioning, and quality of life, at baseline and at follow‐up (n = 63, 58.10% female, mean age = 45.13, SD = 11.06, participation rate = 50.40%). Resilience domains of self‐management of BD, turning point, self‐care, and self‐confidence were significantly associated with mental health indicators at baseline. In addition, self‐confidence at baseline directly predicted an increase in personal recovery at follow‐up, and self‐confidence improvement mediated the relationship between interpersonal support and self‐care at baseline and personal recovery at follow‐up. These findings highlight that resilience domains are significantly associated with positive mental health outcomes in BD and that some predict personal recovery at follow‐up. Moreover, some resilience factors improve other resilience factors over time.     

Assessment of seminal mast cells in infertile men with varicocele after surgical repair

This study aimed to assess seminal mast cells in infertile men associated with varicocele (Vx) pre‐ and post‐surgical repair. Forty‐five infertile men associated with Vx were subjected to history taking and clinical examination. In addition, semen parameters and seminal mast cells stained with 1% toluidine blue were estimated pre‐varicocelectomy and three months post‐varicocelectomy. Vx surgical repair revealed a significant improvement in the mean sperm concentration, progressive sperm motility, total sperm motility and sperm abnormal morphology and a significant decrement in seminal mast cells (mean ± SD, 3.56 ± 2.23 cells per high‐power field (HPF) vs. 2.22 ± 1.06 cells per HPF, p = .01). The pre‐operative mean mast cell count demonstrated significant increases in cases with Vx grade III compared with other Vx grades and in cases with bilateral Vx compared with unilateral Vx cases. Seminal mast cells demonstrated a significant correlation with sperm concentration, progressive sperm motility and total sperm motility and a nonsignificant correlation with age and sperm abnormal morphology. It is concluded that seminal mast cells decrease significantly in infertile men with Vx after surgical repair showing a significant negative correlation with sperm concentration, progressive sperm motility and total sperm motility.     

Long‐term results for living donor liver transplant recipients with hepatocellular carcinoma using intraoperative blood salvage with leukocyte depletion filter

Massive intraoperative bleeding during liver transplantation often requires large amounts of blood products. The goal of this study was to investigate long‐term outcomes of living donor liver transplantation (LDLT) recipients with hepatocellular carcinoma (HCC) who underwent intraoperative use of intraoperative blood salvage (IBS) and leukocyte depletion filter (LDF). In this study, we included 230 LDLT recipients with HCC from two transplantation centers, between February 2002 and December 2007. Group 1 patients (n = 121) underwent intraoperative IBS with LDF and group 2 patients (n = 109) did not. The amount of autotransfused, filtered red blood cells (RBCs) in group 1 was 1590.2 ± 1486.8 ml, which corresponded to 5.9 units of allogenic leukocyte‐depleted RBCs saved. The incidences of renal dysfunction, postoperative bleeding, and urinary tract infection in group 2 were higher than in group 1 (P < 0.05). Recurrence‐free survival rates for 1, 3, and 5 years were 91.3%, 83.3%, and 83.3%, respectively, in group 1, and 84.6%, 79.0%, and 77.4%, respectively, in group 2 (P = 0.314). IBS using LDF does not increase the risk of cancer recurrence during LDLT for recipients with HCC. Therefore, the use of IBS with LDF appears to be safe for LDLT recipients with HCC.     

Neutrophil and platelet‐to‐lymphocyte ratio as new predictors of dropout and recurrence after liver transplantation for hepatocellular cancer

There is increasing evidence that systemic inflammation markers like neutrophil (NLR) and platelet‐to‐lymphocyte ratios (PLR) may play a role in the outcome of hepatocellular cancer (HCC). Between January 1994 and March 2012, 181 patients with HCC were registered on the transplant waiting list: 35 (19.3%) patients dropped out during the waiting period and 146 (80.7%) patients underwent liver transplantation (LT). The median follow‐up of this patient cohort was 4.2 years (IQR: 1.8–8.3). On c‐statistics, the last NLR (AUROC = 67.4; P = 0.05) was the best predictor of dropout. The last PLR had an intermediate statistical ability (AUROC = 66.1; P = 0.07) to predict post‐LT tumor recurrence. Patients with a NLR value >5.4 had poor 5‐year intention‐to‐treat (ITT) survival rates (48.2 vs. 64.5%; P = 0.02). Conversely, PLR better stratified patients in relation to tumor‐free survival (TFS) (80.7 vs. 91.6%; P = 0.02). NLR is a good predictor for the risk of dropout, while PLR is a good predictor for the risk of post‐LT recurrence. Use of these markers, which are all available before LT, may represent an additional tool to refine the selection criteria of HCC liver recipients.     

Misdiagnosis of hepatocellular carcinoma in patients receiving no local‐regional therapy prior to liver transplant: An analysis of the Organ Procurement and Transplantation Network explant pathology form

Patients with T1 hepatocellular carcinoma (HCC) are not eligible for Model for End Stage Liver Disease (MELD) exception for liver transplant (LT) in part due to a high rate of misdiagnosis (no HCC on explant). The likelihood of misdiagnosis for T2 HCC and factors associated with misdiagnosis are unknown. We analyzed the Organ Procurement and Transplantation Network database including 5664 adults who underwent LT from 2012 to 2015 with MELD exception for T2 HCC, and searched for no evidence of HCC in the explant pathology file. We focused on those (n = 324) receiving no local‐regional therapy (LRT) to evaluate the probability of no HCC found in explant. Median waiting time was short at 1.7 months, and 35 (11%) had no HCC on explant. On multivariable logistic regression, factors associated with no HCC on explant were age <50 (OR: 17.3, P < .001), non‐HCV (OR: 5.4, P = .001), and alpha‐fetoprotein <10 (OR: 2.9, P = .04). Tumor size and number were not different between groups. The proportion of misdiagnosis did not change significantly after implementation of Liver Imaging Reporting and Data System (LI‐RADS) for HCC diagnosis. Conclusion: The rate of misdiagnosis was 11% among T2 HCC patients who underwent LT without receiving LRT prior to LT and did not change significantly after implementation of LI‐RADS. More efforts are needed to eliminate unnecessary LT for patients without HCC.     

The effects of general anaesthesia on memory in children: a comparison between propofol and sevoflurane

We studied the effects of general anaesthesia on memory 7 days and 3 months following elective hernia surgery. Sixty children aged between 7 and 13 years were randomly allocated to receive either propofol or sevoflurane. Memory was classified into immediate, short‐term and long‐term memory and assessed using the Wechsler Memory Scale‐Propofol impaired short‐term memory 7 days postoperatively compared with pre‐operative values (image recalling: p = 0.02, figure recognition: p = 0.01, visual reproduction: p = 0.03) but recovered to baseline levels 3 months following surgery. Neither general anaesthetic affected immediate or long‐term memory. We conclude that propofol impairs short‐term memory postoperatively in children.     

Dietary Approach to Stop Hypertension (DASH) diet and risk of renal function decline and all‐cause mortality in renal transplant recipients

Renal transplant recipients (RTR) are at risk of decline of graft function and premature mortality, with high blood pressure as an important risk factor for both. To study the association of the Dietary Approach to Stop Hypertension (DASH) diet with these adverse events, we conducted a prospective cohort study of adult RTR. Dietary data were collected using a validated 177‐item food frequency questionnaire and an overall DASH‐score was obtained. We included 632 stable RTR (mean ± standard deviation age 53.0 ± 12.7 years, 57% men). Mean DASH score was 23.8 ± 4.7. During median follow‐up of 5.3 (interquartile range, 4.1‐6.0) years, 119 (18.8%) RTR had renal function decline, defined as a combined endpoint of doubling of serum creatinine and death‐censored graft failure, and 128 (20.3%) died. In Cox‐regression analyses, RTR in the highest tertile of the DASH score had lower risk of both renal function decline (hazard ratio [HR] = 0.57; 95% confidence interval [CI], 0.33‐0.96, P = .03) and all‐cause mortality (HR = 0.52; 95%CI, 0.32‐0.83, P = .006) compared to the lowest tertile, independent of potential confounders. Adherence to a DASH‐style diet is associated with lower risk of both renal function decline and all‐cause mortality. These results suggest that a healthful diet might benefit long‐term outcome in RTR.     

Standardized measures of frailty predict hospital length of stay following orthotopic liver transplantation for hepatocellular carcinoma

Frailty in liver transplant (LT) waitlisted patients has been shown to predict waitlist mortality. While not currently used to allocate organs, the relationship between preoperative frailty and postoperative outcomes following orthotopic LT needs further elucidation. We determined the frailty status of 50 OLT candidates listed for hepatocellular carcinoma (HCC) and examined relationships between frailty and outcomes on the waitlist and, if transplanted, 30‐day mortality, hospital length of stay (LOS), ICU LOS, and several other secondary outcomes. The overall prevalence of frailty was 30%, and the median natural MELD score for patients was 13. The overall hospital LOS for the frail group was longer (14.5 days [IQR 12‐19]) as compared to the non‐frail group (8 days [IQR 7‐13]); P = .015. Groups also differed in the time to their first PT session (6 days [IQR 4‐15] for the frail vs 4 days [IQR 3‐7] for the non‐frail patients; P = .042). There was no statistically significant difference in other outcomes measures, including ICU LOS and 30‐day mortality. Frailty in OLT patients with diagnosed HCC is a predictor of longer hospital stay and longer time to the first completed PT session independent of preoperative MELD scores.     

Evaluation of a Trauma‐Focused Group Intervention for Unaccompanied Young Refugees: A Pilot Study

Recent research has shown that unaccompanied young refugees (UYR) encounter a wide range of traumatic events during preflight, flight, and resettlement. Although many UYR are resourceful, many develop posttraumatic stress symptoms (PTSS). However, only a small number of vulnerable UYR have access to trauma‐focused interventions. Trauma‐focused group interventions, adapted to the needs of UYR, may be one way of improving their mental health. A total of 29 male UYR between 14 and 18 years of age, mainly from Afghanistan, participated in the evaluation study of a trauma‐focused group intervention entitled Mein Weg (My Way ). The intervention included six sessions of psychoeducation, relaxation, trauma narrative, and cognitive restructuring. Pre–post comparisons of PTSS assessed by the Child and Adolescent Trauma Screen (CATS) were used. At study entry, participants endorsed, on average, eight traumatic events. After the group intervention, the participants reported significantly fewer overall PTSS preintervention mean = 27.6, SD  = 7.9; postintervention mean = 20.7, SD  = 6.3; t (28) = 4.2, p  = .001, Cohen's d  = 0.97. Improvement was especially pronounced in the domains of reexperiencing and avoidance, as well as negative alterations in cognitions and mood. There were 14 participants preintervention and 7 postintervention who fulfilled the PTSD criteria. This pilot study presented initial evidence of the efficacy of the trauma‐focused group intervention with regard to PTSS reduction.
