Nutrition and behavioral health in cystic fibrosis: Eating and body image.

People with CF (pwCF) are at high risk for malnutrition, making nutritional management a critical aspect of CF care. Over the past several decades, optimal nutritional status for pwCF has been defined by body mass index (BMI) based on evidence linking suboptimal BMI to decreased lung function and life expectancy, although more recent changes in CF care may also bring changes to how nutritional health is defined. The historical focus on weight, BMI, and nutrition as key parts of multidisciplinary CF care starting at an early age places pwCF at increased risk for body image concerns and disordered eating. The landscape of CF care is evolving with the approval of highly effective modulator therapies (HEMT) and resulting improvements in growth; however, issues related to body image and eating remain important to consider, especially as past difficulties gaining weight may shift to discomfort with one's weight gain and/or physical appearance. This review aims to describe how body image concerns and disordered eating occur in pwCF across the lifespan; to discuss evidence-based approaches to addressing these concerns; and to identify future directions for research and clinical practice in assessing and treating eating disorders and body image concerns in this population.

Randomized trial of parent-child interaction therapy improves child-welfare parents' behavior, self-regulation, and self-perceptions.

OBJECTIVE: We conducted a large (N = 204) randomized, clinical trial to test the efficacy of parent-child interaction therapy (PCIT) on observed parenting, two key drivers of maladaptive parenting-self-regulation and social cognitions, and child behavior outcomes in a sample of child welfare-involved families. METHOD: Participants were randomly assigned to standard PCIT (n = 120) or services-as-usual (SAU; n = 84). The sample was characterized by low household income, significant exposures to adverse childhood experiences, and substance abuse. Intention-to-treat analyses were conducted on multiply imputed data followed by secondary per-protocol analyses. RESULTS: Significant PCIT effects emerged on (a) increased positive parenting, reduced negative parenting and disruptive child behavior (small-to-medium intention-to-treat effects and medium-to-large per-protocol effects); (b) gains in parent inhibitory control on the stop-signal task (small-to-medium effects); (c) gains in parent-reported emotion regulation and (d) positive, affirming self-perceptions (small-to-medium effects), relative to the SAU control group. PCIT's effects on gains in parent emotion regulation were mediated by reductions in observed negative parenting. No differences in rates of parent commands or child compliance were observed across conditions. Harsh child attributions moderated treatment impact on parenting skills acquisition. PCIT parents who held harsher attributions displayed greater gains in use of labeled praises and declines in negative talk/criticism with their child, than control group parents. CONCLUSIONS: This randomized trial presents the first evidence that PCIT improves inhibitory control and emotion regulation in a child welfare parents and replicates other published trials documenting intervention gains in positive parenting and child behavior in child welfare families.

Parent-Child Interaction Therapy Supports Healthy Eating Behavior in Child Welfare-Involved Children.

OBJECTIVE: We tested the efficacy of standard Parent-Child Interaction Therapy (PCIT), a live-coached, behavioral parent-training program, for modifying problematic eating behaviors in a larger effectiveness trial of PCIT for children involved in the child welfare system. METHOD: Children ages 3-7 years and their parents were randomly assigned to PCIT intervention (n = 120) or services as the usual control (SAU; n = 84) groups in a randomized clinical trial. Children's eating behaviors were assessed pre- and post-intervention via the Child Eating Behaviors Questionnaire (CEBQ). Intention-to-treat analyses were conducted, followed by per-protocol analyses, on treatment-engaging families only. RESULTS: PCIT led to reductions in child welfare-involved children's food responsiveness, speed of food consumption, and tendency to engage in emotional overeating relative to children in the services-as-usual control condition. Standard PCIT may be an effective intervention to promote healthy child eating behaviors in families involved with child welfare, even when food-related behaviors are not directly targeted by the intervention. Public Health Significance: This clinical trial provides evidence that child welfare-involved children who received PCIT experienced significant reductions in maladaptive eating-related behaviors, namely food responsiveness, emotional overeating, and speed of eating. These findings were observed in relation to children in a comparison control group who had access to child welfare services-as-usual.

PCIT engagement and persistence among child welfare-involved families: Associations with harsh parenting, physiological reactivity, and social cognitive processes at intake.

Parent-Child interaction therapy (PCIT) has been shown to improve positive, responsive parenting and lower risk for child maltreatment (CM), including among families who are already involved in the child welfare system. However, higher risk families show higher rates of treatment attrition, limiting effectiveness. In N = 120 child welfare families randomized to PCIT, we tested behavioral and physiological markers of parent self-regulation and socio-cognitive processes assessed at pre-intervention as predictors of retention in PCIT. Results of multinomial logistic regressions indicate that parents who declined treatment displayed more negative parenting, greater perceptions of child responsibility and control in adult-child transactions, respiratory sinus arrhythmia (RSA) increases to a positive dyadic interaction task, and RSA withdrawal to a challenging, dyadic toy clean-up task. Increased odds of dropout during PCIT's child-directed interaction phase were associated with greater parent attentional bias to angry facial cues on an emotional go/no-go task. Hostile attributions about one's child predicted risk for dropout during the parent-directed interaction phase, and readiness for change scores predicted higher odds of treatment completion. Implications for intervening with child welfare-involved families are discussed along with study limitations.

Understanding disparities and barriers associated with pediatric transplant evaluation and time to listing: Moving toward a more comprehensive picture.

BACKGROUND: Delayed time to listing (TTL) for pediatric transplant patients is associated with increased risks of mortality and morbidity. The full range of health disparities, sociodemographic factors, and other barriers associated with delays in listing in the pediatric transplant candidate evaluation process has not been fully examined. METHODS: Retrospective chart reviews were conducted for 183 kidney, liver, and heart transplant candidates ages 0-18 who were referred for evaluation during 2012-2015. Demographic information and potential barriers (e g., social/medical factors, financial concerns) were gathered from pre-transplant evaluations and included in a comprehensive model to evaluate mechanisms that explain differences in TTL. Descriptive statistics, logistic regression models, Cox proportional hazards models, and path analysis were used for analyses. RESULTS: Candidates included 26.8% heart, 33.3% liver, and 39.9% kidney patients. The most common barrier to listing was financial (71.6%), followed by caregiver psychological or substance use (57.9%), and medical problems (49.7%). Higher age, kidney, and liver organ type (relative to the heart), and presence of social, medical, administrative/motivation, and financial barriers were all directly associated with longer TTL. Public insurance was indirectly associated with TTL through social, administrative/motivation, and financial barriers. Organ type was indirectly associated with TTL through financial barriers. CONCLUSIONS: Results suggest social problems, administrative issues, and financial issues act as mechanisms through which insurance type and liver transplant candidates face increased risk of delays in transplant listing time. There are numerous clinical implications and interventions that are warranted to reduce TTL among pediatric transplant candidates with co-occurring barriers.

Bespoke 3D printed eye cover for teen with rhabdomyosarcoma.

BACKGROUND: We report a case of using 3D printing to create a bespoke eye cover for an 18-year-old man with left maxillary alveolar rhabdomyosarcoma. Further, the patient had proptosis causing chemosis and subsequent conjunctival abrasions. This had been managed by taping a large dressing around the eye for a number of weeks previously. METHODS: A 3D scanner was used to capture the surface topography of the patients face. The data were imported into a CAD package and used as a guide to create a bespoke eye cover. The final design was 3D printed in a biocompatible material for use by the patient. RESULTS: The scan, modelling, and printing of the bespoke cover was completed successfully in less than 72 hours. CONCLUSION: 3D printing offers a method to create bespoke solutions for patients in palliative care to meet rare and difficult clinical challenges.

Dyadic synchrony and repair processes are related to preschool children's risk exposure and self-control.

We examined associations between preschool children's cumulative risk exposure, dyadic interaction patterns, and self-control abilities in 238 mother-child dyads. Positive interactive synchrony, relationship ruptures, and latency to repair were micro-coded during a 3-5 minute joint challenge task. Children's self-control was assessed via two laboratory tasks and by parent report. Structural equation modeling and mediation analyses were utilized to examine the direct and indirect effects of cumulative risk on children's observed and parent-reported self-control abilities. Parent-child interactive processes of dyadic synchrony and latency to repair ruptures in synchrony were examined as mediators. Dyadic synchrony and latency to repair ruptures were found to mediate associations between cumulative risk exposure and children's behavioral and parent-reported self-control. Children exposed to more cumulative risk engaged in less dyadic synchrony and experienced longer latencies to repair ruptures with their caregiver, which in turn was associated with lower child self-control. Though cross-sectional, findings suggest dyadic synchrony and repair processes may represent viable mechanistic pathways linking cumulative risk exposure and deficits in child self-control. However, independent replications using longitudinal and experimental intervention designs are needed to determine causal pathways and inform new approaches for targeting the effects of early risk exposure through a focus on two-generational interventions.

Study Protocol: The Coaching Alternative Parenting Strategies (CAPS) Study of Parent-Child Interaction Therapy in Child Welfare Families.

BACKGROUND: Child maltreatment (CM) constitutes a serious public health problem in the United States with parents implicated in a majority of physical abuse and neglect cases. Parent-Child Interaction Therapy (PCIT) is an intensive intervention for CM families that uses innovative "bug-in-ear" coaching to improve parenting and child outcomes, and reduce CM recidivism; however, the mechanisms underlying its effects are little understood. The Coaching Alternative Parenting Strategies (CAPS) study aims to clarify the behavioral, neural, and physiological mechanisms of action in PCIT that support positive changes in parenting, improve parent and child self-regulation and social perceptions, and reduce CM in child welfare-involved families. METHODS: The CAPS study includes 204 child welfare-involved parent-child dyads recruited from Oregon Department of Human Services to participate in a randomized controlled trial of PCIT versus a services-as-usual control condition (clinicaltrials.gov, NCT02684903). Children ages 3-8 years at study entry and their parents complete a pre-treatment assessment prior to randomization and a post-treatment assessment 9-12 months post study entry. Dyads randomized to PCIT complete an additional, abbreviated assessment at mid-treatment. Each assessment includes individual and joint measures of parents' and children's cardiac physiology at rest, during experimental tasks, and in recovery; observational coding of parent-child interactions; and individual electroencephalogram (EEG) sessions including attentional and cognitive control tasks. In addition, parents and children complete an emotion regulation task and parents report on their own and their child's adverse childhood experiences and socio-cognitive processes, while children complete a cognitive screen and a behavioral measure of inhibitory control. Parents and children also provide anthropometric measures of allostatic load and 4-5 whole blood spots to assess inflammation and immune markers. CM recidivism is assessed for all study families at 6-month follow-up. Post-treatment and follow-up assessments are currently underway. DISCUSSION: Knowledge gained from this study will clarify PCIT effects on neurobehavioral target mechanisms of change in predicting CM risk reduction, positive, responsive parenting, and children's outcomes. This knowledge can help to guide efforts to tailor and adapt PCIT to vary in dosage and cost on the basis of individual differences in CM-risk factors.

Couple Adjustment and Differentiation of Self in the United States, Italy, and Spain: A Cross-Cultural Study.

This study comprises a first attempt to explore a cross-cultural application of Bowen family systems theory and examines the relationship between differentiation of self and couple adjustment using measurement invariance. A sample of 2,141 individuals (n = 915 from the United States; n = 635 from Italy; n = 591 from Spain) completed measures of differentiation of self (DSI-R; Skowron & Schmitt, J Marital Fam Ther, 29, 2003, 209) and couple adjustment (DAS; Spanier, J Marriage Fam, 38, 1976, 15). Results showed evidence of partial measurement equivalence for the DSI-R across the three samples. Additionally, results from latent regression showed that less emotional cutoff predicted greater couple adjustment in the United States, Spain, and Italy, whereas greater emotional reactivity predicted poorer couple adjustment only in the more collectivistic cultures, Spain and Italy. Our findings are consistent with prior empirical studies, which suggest that emotional cutoff is a strong predictor of relationship adjustment. The use of measurement invariance provides a foundation for future studies to continue employing rigorous statistical methods when examining constructs across different cultures. The findings highlight culture-specific similarities and differences in differentiation that may benefit practitioners by informing psychotherapy with individuals, couples, or families from diverse populations.

Este estudio constituye un primer intento de explorar la aplicabilidad intercultural de la teoría de sistemas familiares de Bowen y de analizar la relación entre la diferenciación del self y el ajuste de la pareja utilizando un análisis de invariancia. Una muestra de 2.141 personas (n = 915 de Estados Unidos; n = 635 de Italia; n = 591 de España), completaron medidas de diferenciación del self (DSI-R; Skowron & Schmitt, 2003) y de ajuste diádico (DAS; Spanier, 1976). Los resultados aportan pruebas de equivalencia parcial de las medidas del DSI-R entre las tres muestras. Además, los resultados de la regresión latente indicaron que un menor corte emocional predijo mayor ajuste de la pareja en Estados Unidos, España e Italia, mientras que una mayor reactividad emocional predijo un menor ajuste de la pareja solo en las culturas más colectivistas: España e Italia. Nuestros resultados concuerdan con estudios empíricos anteriores, que sugieren que el corte emocional es un fuerte predictor del ajuste relacional. El uso del análisis de invariancia ofrece una base para que futuros estudios sigan utilizando métodos estadísticos rigurosos cuando se examinan constructos entre culturas diferentes. Los resultados ponen de manifiesto diferencias y similitudes específicas en la diferenciación entre las culturas estudiadas, que pueden ayudar a los profesionales orientando la psicoterapia de personas, parejas o familias de poblaciones diversas.

Systemic Molecular Mediators of Inflammation Differentiate Between Crohn's Disease and Ulcerative Colitis, Implicating Threshold Levels of IL-10 and Relative Ratios of Pro-inflammatory Cytokines in Therapy.

BACKGROUND AND AIMS: Faecal diversion is associated with improvements in Crohn's disease but not ulcerative colitis, indicating that differing mechanisms mediate the diseases. This study aimed to investigate levels of systemic mediators of inflammation, including fibrocytes and cytokines, [1] in patients with Crohn's disease and ulcerative colitis preoperatively compared with healthy controls and [2] in patients with Crohn's disease and ulcerative colitis prior to and following faecal diversion. METHODS: Blood samples were obtained from healthy individuals and patients with Crohn's disease or ulcerative colitis. Levels of circulating fibrocytes were quantified using flow cytometric analysis and their potential relationship to risk factors of inflammatory bowel disease were determined. Levels of circulating cytokines involved in inflammation and fibrocyte recruitment and differentiation were investigated. RESULTS: Circulating fibrocytes were elevated in Crohn's disease and ulcerative colitis patients when compared with healthy controls. Smoking, or a history of smoking, was associated with increases in circulating fibrocytes in Crohn's disease, but not ulcerative colitis. Cytokines involved in fibrocyte recruitment were increased in Crohn's disease patients, whereas patients with ulcerative colitis displayed increased levels of pro-inflammatory cytokines. Faecal diversion in Crohn's disease patients resulted in decreased circulating fibrocytes, pro-inflammatory cytokines, and TGF-ß1, and increased IL-10, whereas the inverse was observed in ulcerative colitis patients. CONCLUSIONS: The clinical effect of faecal diversion in Crohn's disease and ulcerative colitis may be explained by differing circulating fibrocyte and cytokine responses. Such differences aid in understanding the disease mechanisms and suggest a new therapeutic strategy for inflammatory bowel disease.

Recollections of positive early caregiving relate to sympathetic nervous system activation and chronic inflammation in subsequent generations.

To understand links between early experience and biomarkers of peripheral physiology in adulthood, this study examined associations between quality of early caregiving and markers of sympathetic activation and chronic inflammation in a sample of 52 low-income mothers and their preschool-aged children. Mothers reported on levels of positive caregiving experienced during childhood using the Structural Analysis of Social Behavior-Intrex. Mother and child sympathetic activation was indexed via pre-ejection period (PEP) at rest, during a dyadic social engagement task, and for children, while interacting with an unfamiliar adult. C-reactive protein (CRP) was collected using whole blood spots to assess levels of low-grade chronic inflammation. Results showed that mothers who reported experiencing more warm guidance and support for autonomy in early childhood displayed lower resting sympathetic nervous system activation (i.e., longer PEP) and lower chronic inflammation (i.e., CRP levels). Further, lower maternal chronic inflammation levels were associated with lower sympathetic activation (i.e., longer PEP) in their children at rest, and during social interactions with mother and a female stranger.

Incidental small cell carcinoma of the gallbladder-an unexpected finding at elective cholecystectomy.

A 69-year-old woman was admitted electively for a laparoscopic cholecystectomy. Pre-operatively she had an ultrasound abdomen which demonstrated a large gallbladder (GB) stone. Intraoperatively, a nodule was noted on the liver supero-lateral to GB. The procedure was subsequently converted to open and the lesion was resected en-bloc with GB. The histology result showed small cell carcinoma (SCC) of the gallbladder with invasion into the liver parenchyma. A staging computerized tomographic of the thorax, abdomen and pelvis was performed. This demonstrated enlarged adenopathy locally and systemically with metastasis to medial segment of the left hepatic lobe and right lung. Following multi-disciplinary team meeting she was referred to Oncology for chemotherapy. The patient has survived for 7 months after the initial diagnosis of SCC.

Veterinarian Nominated Common Conditions of Rabbits and Guinea Pigs Compared with Published Literature.

Rabbits and guinea pigs are increasingly popular pets in the UK, yet little is known about their common ailments, or how these relate to what appears in the published literature. The aim of this study was to characterise the common conditions of rabbits and guinea pigs, and to compare these with the topics found in the published literature. Information about the common conditions seen in rabbits and guinea pigs in clinical practice was obtained from a survey of UK veterinarians. The common conditions seen were compared with results from a structured literature search. Conditions relating to the dental (29.9%), and skin (37.6%) body systems were commonly nominated by veterinarians for rabbits and guinea pigs, respectively. A total of 655 rabbit and 1086 guinea pig citations were examined and there appeared to be a mismatch between the conditions nominated in the veterinary questionnaire, and those found in the literature. This is the first time that the published literature has been compared to the nominated caseload of veterinarians in practice, and there is concern that the literature about rabbits and guinea pigs may not be representative of, or relevant to the caseload seen in clinical practice. This is of importance for clinicians being able to apply an objective, evidence-based approach. The publishing of clinically-relevant, research-based evidence should be prioritised.

Intrinsic hippocampal activity as a biomarker for cognition and symptoms in schizophrenia.

OBJECTIVE: Identification of biomarkers for cognitive dysfunction in schizophrenia is a priority for psychiatry research. Functional imaging studies suggest that intrinsic "resting state" hippocampal hyperactivity is a characteristic feature of schizophrenia. The relationships between this phenotype and symptoms of the illness, however, are largely unexplored. The authors examined resting hippocampal activity in schizophrenia patients and healthy comparison subjects and analyzed the relationship between intrinsic hippocampal activity and cognitive function in patients as measured by the MATRICS Consensus Cognitive Battery (MCCB). METHOD: Twenty-eight schizophrenia patients and 28 age-matched healthy comparison subjects underwent functional "resting state" 3-T MR scanning. Hippocampal activity was extracted by group independent component analysis. Correlation analyses were used to examine the relationship between hippocampal activity and MCCB composite and domain scores in patients, as well as between hippocampal activity and positive and negative symptoms. RESULTS: Greater activity of the right hippocampus at rest was observed in patients relative to comparison subjects. In patients, a significant negative correlation was observed between right hippocampal activity and composite MCCB T-score. The correlation was driven by the MCCB domains of attention/vigilance, working memory, and visual learning. Hippocampal activity was positively correlated with negative symptoms. MCCB scores were inversely correlated with negative symptoms. CONCLUSIONS: These findings suggest that greater intrinsic hippocampal activity is a characteristic feature of schizophrenia that is broadly associated with cognitive dysfunction, and they support hippocampal activity as a candidate biomarker for therapeutic development.

Multidimensional sexual perfectionism.

Perfectionism is a multidimensional personality characteristic that can affect all areas of life. This article presents the first systematic investigation of multidimensional perfectionism in the domain of sexuality exploring the unique relationships that different forms of sexual perfectionism show with positive and negative aspects of sexuality. A sample of 272 university students (52 male, 220 female) completed measures of four forms of sexual perfectionism: self-oriented, partner-oriented, partner-prescribed, and socially prescribed. In addition, they completed measures of sexual esteem, sexual self-efficacy, sexual optimism, sex life satisfaction (capturing positive aspects of sexuality) and sexual problem self-blame, sexual anxiety, sexual depression, and negative sexual perfectionism cognitions during sex (capturing negative aspects). Results showed unique patterns of relationships for the four forms of sexual perfectionism, suggesting that partner-prescribed and socially prescribed sexual perfectionism are maladaptive forms of sexual perfectionism associated with negative aspects of sexuality whereas self-oriented and partner-oriented sexual perfectionism emerged as ambivalent forms associated with positive and negative aspects.

Early sensory processing deficits predict sensitivity to distraction in schizophrenia.

Patients with schizophrenia frequently report difficulties paying attention during important tasks, because they are distracted by noise in the environment. The neurobiological mechanism underlying this problem is, however, poorly understood. The goal of this study was to determine if early sensory processing deficits contribute to sensitivity to distracting noise in schizophrenia. To that end, we examined the effect of environmentally relevant distracting noise on performance of an attention task in 19 patients with schizophrenia and 22 age and gender-matched healthy comparison subjects. Using electroencephalography, P50 auditory gating ratios also were measured in the same subjects and were examined for their relationship to noise-induced changes in performance on the attention task. Positive symptoms also were evaluated in patients. Distracting noise caused a greater increase in reaction time in patients, relative to comparison subjects, on the attention task. Higher P50 auditory gating ratios also were observed in patients. P50 gating ratio significantly correlated with the magnitude of noise-induced increase in reaction time. Noise-induced increase in reaction time was associated with delusional thoughts in patients. P50 ratios were associated with delusional thoughts and hallucinations in patients. In conclusion, the observation of noise effects on attention in patients is consistent with subjective reports from patients. The observed relationship between noise effects on reaction time and P50 auditory gating supports the hypothesis that early inhibitory processing deficits may contribute to susceptibility to distraction in the illness.
