This article discusses 3 ways in which adaptive developmental mechanisms may produce maladaptive outcomes. First, natural selection may favor risky strategies that enhance fitness on average but which have detrimental consequences for a subset of individuals. Second, mismatch may result when organisms experience environmental change during…

Although illness perception has been shown to be associated with illness outcomes in various chronic physical diseases, the association of illness perception and rumination are not well elucidated in mental disorders. This study aims to investigate the mediational effects of adaptive and maladaptive rumination in the relationship between illness perception and negative emotions (depression, anxiety and stress) in male and female patients (N=110) suffering from depressive disorders. The results showed that maladaptive rumination mediated the relationship between illness perception and negative emotions in both male and female depressive patients. However, no mediating effects of adaptive rumination were found in the relationship between illness perception and negative emotion. Maladaptive rumination mediated the relationship between perceived identity, chronicity of illness, consequences of illness and emotional representation of illness and negative emotions in males. It also mediated the relationship between perceived identity and emotional representation of illness and negative emotions in females. The results, possible clinical implications and limitations of this study are also discussed.

Transactional theories of development suggest that displaying high levels of antisocial behavior early in life and persistently over time causes disruption in multiple life domains, which in turn places individuals at risk for negative life outcomes. We used longitudinal data from 1,137 primarily African American urban youth (49.1% female) to determine whether different trajectories of aggressive and disruptive behavior problems were associated with a range of negative life outcomes in young adulthood. General growth mixture modeling was used to classify the youths' patterns of aggressive-disruptive behavior across elementary school. These trajectories were then used to predict early sexual activity, early pregnancy, school dropout, unemployment, and drug abuse in young adulthood. The trajectories predicted the number but not type of negative life outcomes experienced. Girls with the chronic high aggression-disruption (CHAD) pattern experienced more negative outcomes than girls with consistently moderate levels, who were at greater risk than nonaggressive-nondisruptive girls. Boys with CHAD and boys with an increasing pattern had equal levels of risk for experiencing negative outcomes. The findings are consistent with transactional models of development and have implications for preventive interventions.

Randomized clinical trials have demonstrated that the increased intake of ω-3 polyunsaturated fatty acids significantly reduces the risk of ischemic cardiovascular disease, but no investigations have been performed in hereditary cardiomyopathies with diffusely damaged myocardium. In the present study, δ-sarcoglycan-null cardiomyopathic hamsters were fed from weaning to death with an α-linolenic acid (ALA)-enriched versus standard diet. Results demonstrated a great accumulation of ALA and eicosapentaenoic acid and an increased eicosapentaenoic/arachidonic acid ratio in cardiomyopathic hamster hearts, correlating with the preservation of myocardial structure and function. In fact, ALA administration preserved plasmalemma and mitochondrial membrane integrity, thus maintaining proper cell/extracellular matrix contacts and signaling, as well as a normal gene expression profile (myosin heavy chain isoforms, atrial natriuretic peptide, transforming growth factor-β1) and a limited extension of fibrotic areas within ALA-fed cardiomyopathic hearts. Consequently, hemodynamic indexes were safeguarded, and more than 60% of ALA-fed animals were still alive (mean survival time, 293 ± 141.8 days) when all those fed with standard diet were deceased (mean survival time, 175.9 ± 56 days). Therefore, the clinically evident beneficial effects of ω-3 polyunsaturated fatty acids are mainly related to preservation of myocardium structure and function and the attenuation of myocardial fibrosis.

To investigate the usefulness of myocardial scintigraphy with radioiodinated 15-(p-iodophenyl)-3-R,S-methylpentadecanoic acid (BMIPP) in cardiomyopathy, quantitative dual tracer autoradiographic study with /sup 201/Tl and (/sup 125/I)BMIPP was performed in 27 cardiomyopathic Bio 14.6 Syrian hamsters and eight normal hamsters. Furthermore, 16 Bio 14.6 Syrian hamsters aged 21 days were divided into verapamil-treated (during 70 days) and control groups (respectively, n = 8), and autoradiography with /sup 201/Tl and (/sup 125/I)BMIPP was performed. Quantitative autoradiography demonstrated an uncoupling of /sup 201/Tl and (/sup 125/I)BMIPP distributions and a regional heterogeneity of (/sup 125/I)BMIPP distribution in cardiomyopathic hamsters aged more than 2 mo, while normal hamsters showed only mild heterogeneity of (/sup 125/I)BMIPP distribution without an uncoupling of tracers. Age-matched comparison between normal and cardiomyopathic hamsters (5-8 mo old) demonstrated that a difference between their (/sup 125/I)BMIPP distributions are more marked than that between their /sup 201/Tl distributions. Furthermore, (/sup 125/I)BMIPP visualized effects of verapamil on cardiomyopathy more distinctly than did /sup 201/Tl. In conclusion, myocardial imaging with (/sup 123/I)BMIPP could be useful for investigating cardiomyopathy and evaluating the efficacy of therapeutic intervention in patients with cardiomyopathy.

To evaluate the influence of T-1032 (methyl2-(4-aminophenyl)-1,2-dihydro-1-oxo-7-(2-pyridylmethoxy)-4-(3,4,5-trimethoxyphenyl)-3-isoquinoline carboxylate sulfate), a potent and relatively selective phosphodiesterase 5 inhibitor, on chronic heart failure, we examined the acute hemodynamic profile of T-1032 and its chronic effect on the survival of Bio 14.6 cardiomyopathic hamsters. In the acute study, T-1032 (1, 10, 100 microg/kg) was administered intravenously by means of a dose-escalating procedure in 55-week-old hamsters. T-1032 significantly reduced both the right and left ventricular end-diastolic pressure in a dose-dependent manner. T-1032 modestly reduced the systemic arterial pressure at the highest dose (100 microg/kg i.v.). T-1032 did not change the heart rate or left ventricular dp/dt(max). In the survival study, chronic administration of T-1032 (50 and 500 ppm in a diet) increased survival, and the survival rate was 24.2%, 45.4% and 48.5% in the control, 50 and 500 ppm-treated groups, respectively. The median survival was 55, 58 and 58 weeks in control, 50 and 500 ppm-treated groups, respectively. Analysis of the survival curves revealed that T-1032 (500 ppm) significantly increased the survival of these hamsters (P<0.05 vs. control). It was concluded that T-1032 had beneficial hemodynamic effects on heart failure in Bio 14.6 cardiomyopathic hamsters, and the favorable hemodynamic changes induced by T-1032 were partly related to the increase in the survival of these hamsters. Phosphodiesterase type 5 inhibitors may have therapeutic potential for the treatment of chronic heart failure.

Significant connective tissue abnormalities occurring in hearts of cardiomyopathic Syrian hamsters are reported. These abnormalities include a pronounced loss of the intrinsic connective tissue skeletal framework around foci of myocytolytic necrosis within the non-necrotic myocardium. These changes were demonstrated by a silver impregnation technique, and they were confirmed by scanning electron microscopy. Quantitation demonstrated more than a twofold increase in the area of ventricular wall affected by pathologic changes, when the connective tissue alterations were included with the myocardial necrosis. In addition, the authors also observed focal, thick "tethering" connective tissue fibers at the termini of necrotic lesions, seemingly connecting them to normal muscle. These connective tissue abnormalities may contribute to the progressive loss of ventricular function that occurs in this model of cardiomyopathy. They may permit greater wall thinning than would occur with focal necrosis alone, and they may increase focal mural stiffness in the tethered regions. Further investigation of the pathogenesis of these changes and their mechanical significance is indicated. Images Figure 5 Figure 6 Figure 1 Figure 2 Figure 3 Figure 4 PMID:3578490

Unhealthy eating attitudes and poor body esteem often lead to adverse outcomes (e.g., eating disorders). Prior research has identified two risk factors for these outcomes--endorsement of the superhero ideal and maladaptive perfectionism--and has suggested that these factors may interact to predict unhealthy eating attitudes and body esteem. The current study examined the interaction between the superhero ideal and maladaptive perfectionism as predictors of unhealthy eating attitudes and body esteem among 161 12- to 14-year-olds (74 males, 87 females). Maladaptive perfectionism moderated the relation between endorsement of the superhero ideal and unhealthy eating attitudes for girls only, such that endorsement of the superhero ideal was significantly associated with unhealthy eating attitudes only for adolescents with high levels of maladaptive perfectionism. The moderation model was not significant for body esteem. Prevention strategies should focus on reducing endorsement of the superhero ideal when there are high levels of maladaptive perfectionism.

Family members of women substance users may be at risk for stress-related problems. Family coping responses may affect outcomes for both families and women in treatment. Eighty-two women in treatment for substance use disorders (56 with comorbid psychiatric conditions) and 82 family members were interviewed. Stressors related to women’s disorders were significantly related to increased family member burden. Women’s behavioral problems predicted greater family member Worry, Displeasure, and Impact. Extent of women’s drug or alcohol use predicted greater family member Stigma and Impact. Family member maladaptive coping partially mediated relationships between family member stressors and family member Displeasure and Impact. Family member maladaptive coping also functioned as a moderator between the stressors and Impact. PMID:21499498

The identification of modifiable risk factors for glaucoma progression is needed. Our objective was to determine whether maladaptive coping styles are associated with recent glaucoma progression or worse visual field mean deviation.A hospital-based case-control study was conducted in the Glaucoma Service of Maisonneuve-Rosemont Hospital in Montreal, Canada. Patients with primary open angle glaucoma or normal tension glaucoma with ≥4 years of follow-up and ≥5 Humphrey visual fields were included. Cases had recent visual field progression as defined according to the Early Manifest Glaucoma Trial pattern change probability maps. Controls had stable visual fields. The Brief Cope questionnaire, a 28-item questionnaire about 14 different ways of coping with the stress of a chronic disease, was asked. Questions were also asked about demographic and medical factors, and the medical chart was examined. Outcomes included glaucoma progression (yes, no) and visual field mean deviation. Logistic and linear regressions were used.A total of 180 patients were included (82 progressors and 98 nonprogressors). Although none of the 14 coping scales were associated with glaucoma progression (P > 0.05), higher denial was correlated with worse visual field mean deviation (r = -0.173, P = 0.024). In a linear regression model including age, sex, education, depression, intraocular pressure, and family history of glaucoma, greater levels of denial (β = -1.37, 95% confidence interval [CI] -2.32, -0.41), Haitian ethnicity (β = -7.78, 95% CI -12.52, -3.04), and the number of glaucoma medications (β = -1.20, 95% CI -2.00, -0.38) were statistically significantly associated with visual field mean deviation.The maladaptive coping mechanism of denial was a risk factor for worse visual field mean deviation. Further prospective research will be required to verify the pathways by which denial may exert an effect on glaucomatous visual field loss.

To determine a possible basis for the decreased action of atrial natriuretic factors (ANF) in congestive heart failure, we compared the cardiomyopathic hamster (CMH) in frank congestive failure, and the age-matched, normal, F1B strain of Golden Syrian Hamsters. Scatchard analysis of competitive binding studies revealed two classes of glomerular receptors. The CMH exhibited decreased binding overall and a markedly decreased number of high affinity receptors but comparable receptor affinity compared to the F1B. In contrast, the low affinity receptor population in the CMH had a much greater affinity compared to the F1B while receptor number was similar. Plasma ANF levels were substantially elevated in the CMH compared to the F1B and in-vitro generation of cGMP was significantly lower in the CMH. Such abnormalities could contribute to the resistance to ANF in this disease.

Existing treatments for maladaptive interpersonal dependency and dependent personality disorder do not meet basic scientific standards for effectiveness. The present investigation tested the efficacy of a mindfulness-based approach: mindfulness therapy for maladaptive interpersonal dependency (MT-MID). Forty-eight participants who reported consistently high levels of maladaptive dependency (i.e., scored higher than 1 standard deviation above the mean on the Interpersonal Dependency Inventory at two separate assessments) were randomized to either 5 sessions of MT-MID or a minimal contact control. Five self-reported outcomes (mindfulness, maladaptive interpersonal dependency, helplessness, fears of negative evaluation, and excessive reassurance seeking) were assessed at pretreatment, posttreatment, and a 4-week follow-up. Intent-to-treat analyses indicated that MT-MID yielded greater improvements than the control on all 5 outcomes at posttreatment (median d=1.61) and follow-up (median d=1.51). Participants assigned to MT-MID were more likely than control participants to meet criteria for clinically significant change at posttreatment (56.5% vs. 0%) and follow-up (42.9% vs. 0%). There was also evidence that increases in mindfulness mediated the dependency-related improvements. These results provide preliminary support for the efficacy of a mindfulness-based approach for treating the symptoms of maladaptive dependency.

Anthracyclines, most powerful anticancer agents, suffer from their cardiotoxic effects, which may be due to the induction of oxidative stress. Carvedilol, a third-generation, nonselective β-adrenoreceptor antagonist, possesses both reactive oxygen species (ROS) scavenging and ROS suppressive effects. It showed protective effects against daunorubicin- (DNR-) induced cardiac toxicity by reducing oxidative stress and apoptosis. This study therefore was designed to examine the effects of carvedilol on DNR-induced cardiomyopathic rats, focused on the changes of left ventricular function, cardiac fibrosis, and hypertrophy. Carvedilol increased survival rate, prevented systolic and diastolic dysfunction, and attenuated myocardial fibrosis and hypertrophy. DNR alone treated rats showed upregulated myocardial expression of ANP, PKC-α, OPN, and TGF-β1 and downregulation of GATA-4 in comparison with control, and treatment with carvedilol significantly reversed these changes. The results of the present study add the available evidences on the cardioprotection by carvedilol when associated with anthracyclines and explain the mechanisms underlying the benefits of their coadministration.

Although reasonably strong support has been obtained for the Five-Factor Model's (FFM) ability to account for the existing personality disorder (PD) constructs, the support for obsessive-compulsive PD (OCPD) and dependent PD (DPD) has been relatively less consistent. Specifically, the expected correlation between OCPD and the FFM trait of Conscientiousness has varied in magnitude across studies while DPD has, at times, also evinced rather weak relationships with FFM Agreeableness. We determined that these inconsistencies were due primarily to the reliance on FFM measures that lack adequate fidelity to assess the maladaptive aspects of high Conscientiousness and Agreeableness. When alternative measures were utilized, the correlations were generally large and in line with expectations. We conclude that OCPD and DPD can be fruitfully conceptualized within the FFM but encourage the use of measures that provide a comprehensive assessment of both the adaptive and maladaptive aspects of the FFM traits.

We address adaptive vs. maladaptive responses to hypoxemia in healthy humans and hypoxic-tolerant species during wakefulness, sleep, and exercise. Types of hypoxemia discussed include short-term and life-long residence at high altitudes, the intermittent hypoxemia attending sleep apnea, or training regimens prescribed for endurance athletes. We propose that hypoxia presents an insult to O2 transport, which is poorly tolerated in most humans because of the physiological cost. PMID:26136544

The prevalence of sleep apnea is very high in patients with heart failure (HF). The aims of this study were to investigate the influence of intermittent hypoxia (IH) on the failing heart and to evaluate the antioxidant effect of hydrogen gas. Normal male Syrian hamsters (n = 22) and cardiomyopathic (CM) hamsters (n = 33) were exposed to IH (repeated cycles of 1.5 min of 5% oxygen and 5 min of 21% oxygen for 8 h during the daytime) or normoxia for 14 days. Hydrogen gas (3.05 vol/100 vol) was inhaled by some CM hamsters during hypoxia. IH increased the ratio of early diastolic mitral inflow velocity to mitral annulus velocity (E/e', 21.8 vs. 16.9) but did not affect the LV ejection fraction (EF) in normal Syrian hamsters. However, IH increased E/e' (29.4 vs. 21.5) and significantly decreased the EF (37.2 vs. 47.2%) in CM hamsters. IH also increased the cardiomyocyte cross-sectional area (672 vs. 443 μm(2)) and interstitial fibrosis (29.9 vs. 9.6%), along with elevation of oxidative stress and superoxide production in the left ventricular (LV) myocardium. Furthermore, IH significantly increased the expression of brain natriuretic peptide, β-myosin heavy chain, c-fos, and c-jun mRNA in CM hamsters. Hydrogen gas inhalation significantly decreased both oxidative stress and embryonic gene expression, thus preserving cardiac function in CM hamsters. In conclusion, IH accelerated LV remodeling in CM hamsters, at least partly by increasing oxidative stress in the failing heart. These findings might explain the poor prognosis of patients with HF and sleep apnea.

Both maladaptive and adaptive emotion regulation strategies have been linked with psychopathology. However, previous studies have largely examined them separately, and little research has examined the interplay of these strategies cross-sectionally or longitudinally in patients undergoing psychological treatment. This study examined the use and interplay of adaptive and maladaptive emotion regulation strategies in 81 patients receiving cognitive-behavioral interventions for comorbid alcohol use and anxiety disorders. Patients completed measures of emotion regulation strategy use and symptoms of psychopathology pre- and post-treatment. Cross-sectionally, higher use of maladaptive strategies (e.g., denial) was significantly related to higher psychopathology pre- and post-treatment, whereas higher use of adaptive strategies (e.g., acceptance) only significantly related to lower psychopathology post-treatment. Prospectively, changes in maladaptive strategies, but not changes in adaptive strategies, were significantly associated with post-treatment psychopathology. However, for patients with higher pre-treatment maladaptive strategy use, gains in adaptive strategies were significantly associated with lower post-treatment psychopathology. These findings suggest that psychological treatments may maximize efficacy by considering patient skill use at treatment outset. By better understanding a patient's initial emotion regulation skills, clinicians may be better able to optimize treatment outcomes by emphasizing maladaptive strategy use reduction predominately, or in conjunction with increasing adaptive skill use.

The past few years have witnessed an extraordinary number of important developments in the study of compensatory and maladaptive responses to cardiac dysfunction. It now seems clear that the process whereby the heart remodels in response to left ventricular injury is of paramount importance in the expression of clinical heart failure. There have been parallel attempts by basic scientists and clinical investigators to understand better the fundamental biologic processes that underlie remodeling and to assess numerous new treatments--especially angiotensin-converting enzyme inhibitors. A general consensus seems to be emerging that holds that the response of the heart to acute injury includes a number of highly compensatory and adaptive mechanisms that ultimately become maladaptive and contribute to cardiomegaly and severe congestive heart failure. Such mechanisms undoubtedly include local and systemic release of cytokines, peptides, and neurohormones, and altered loading conditions leading to unusual mechanical forces on cardiac myocytes and other cells of the heart. At the organ level there is hypertrophy, dilatation and growth of the interstitium. Preliminary evidence also suggests there may be some "remodeling" at the cardiac myocyte level. Reduction in peripheral vasodilator reserve is seen in experimental animal models of heart failure. Patients with heart failure also develop an endothelial-dependent form of peripheral vascular dysfunction expressed clinically as an attenuated ability to dilate in response to such stimuli as acetylcholine. The transition point whereby these myocardial and peripheral vascular abnormalities become clearly dysfunctional and contribute toward the full clinical expression of heart failure remains to be further investigated.

A core manifestation of post-traumatic stress disorder (PTSD) is a disconnection between physiological state and psychological or behavioral processes necessary to adequately respond to environmental demands. Patients with PTSD experience abnormal oscillations in autonomic states supporting either fight and flight behaviors or withdrawal, immobilization, and dissociation without an intervening “calm” state that would provide opportunities for positive social interactions. This defensive autonomic disposition is adaptive in dangerous and life threatening situations, but in the context of every-day life may lead to significant psychosocial distress and deteriorating social relationships. The perpetuation of these maladaptive autonomic responses may contribute to the development of comorbid mental health issues such as depression, loneliness, and hostility that further modify the nature of cardiovascular behavior in the context of internal and external stressors. Over time, changes in autonomic, endocrine, and immune function contribute to deteriorating health, which is potently expressed in brain dysfunction and cardiovascular disease. In this theoretical review paper, we present an overview of the literature on the chronic health effects of PTSD. We discuss the brain networks underlying PTSD in the context of autonomic efferent and afferent contributions and how disruption of these networks leads to poor health outcomes. Finally, we discuss treatment approaches based on our theoretical model of PTSD. PMID:25653631
Despite theoretical understanding and empirical detection of local adaptation in natural environments, our knowledge of such divergence in fragmented habitats remains limited, especially in the context of microgeographic spatial scales and contemporary time scales. I used a combination of reciprocal transplant and common garden exposure experiments to evaluate potential microgeographic divergence in a pool-breeding amphibian occupying a landscape fragmented by roads. As indicated by reduced rates of survival and increased rates of malformation, I found evidence for maladaptation in road adjacent populations. This response is in direct counterpoint to recently described local adaption by a cohabiting species of amphibian. These results suggest that while divergence might commonly follow habitat modification, the direction of its outcome cannot be generalized even in identical habitats. Further, maladaptive responses can be associated with a more generalized depression effect that transcends the local environment. Alongside recent reports, these results suggest that maladaptive responses may be an emerging consequence of human-induced environmental change. Thus future studies should carefully consider the population unit as a key level for inference. PMID:24109548

Runaway and homeless youth often have a constellation of background behavioral, emotional, and familial problems that contribute to stress and maladaptive behaviors, which, in turn, can lead to self-harming and suicidal behaviors. The current study examined the roles of stress and maladaptive behaviors as mediators between demographic and psychosocial background characteristics and self-injurious outcomes through the lens of the stress process paradigm. The model was tested in a sample of runaway and homeless youth from Los Angeles County (N = 474, age 12-24, 41 % female, 17 % White, 32.5 % African American, 21.5 % Hispanic/Latino). Background variables (gender, age, sexual minority status, parental drug use history, and emotional distress) predicted hypothesized mediators of maladaptive behaviors and recent stress. In turn, it was hypothesized that the mediators would predict self-harming behaviors and suicide attempts in the last 3 months. Females and LGBT (lesbian, gay, bisexual, transgender) youth were more likely to have self-harmed and attempted suicide; younger participants reported more self-harming. The mediating constructs were associated more highly with self-harming than suicide attempts bivariately, although differences were modest. Maladaptive behaviors and recent stress were significant predictors of self-harm, whereas only recent stress was a significant predictor of suicide attempts. All background factors were significant predictors of recent stress. Older age, a history of parental drug use, and greater emotional distress predicted problem drug use. Males, younger participants, and participants with emotional distress reported more delinquent behaviors. Significant indirect effects on self-harming behaviors were mediated through stress and maladaptive behaviors. The hypothesized paradigm was useful in explaining the associations among background factors and self-injurious outcomes and the influence of mediating factors on these

Abstract Background Psychiatric treatment for children and adolescents with clinically significant aggression is common and often involves the use of antipsychotic medications. Increasingly, pediatricians are initiating or managing such treatments despite limited evidence on optimal diagnostic, psychosocial, and medication approaches for pediatric aggression. Aims The objective of this study was to gather clinicians' and researchers' expertise concerning the treatment of maladaptive aggression, using expert consensus survey methods to aid the development of guidelines for pediatricians and psychiatrists on the outpatient treatment of maladaptive aggression in youth (T-MAY). Methods Forty-six experts (psychiatrists, pediatricians, and researchers) with >10 years of clinical and/or research experience in the treatment of pediatric aggression completed a 27-item survey (>400 treatment alternatives) about optimal diagnostic, psychosocial, and medication treatments. Data were analyzed using descriptive statistics and confidence intervals. Results Expert consensus methodology clearly differentiated optimal versus nonoptimal treatment strategies for maladaptive aggression. In contrast to current practice trends, results indicated that experts support the use of psychosocial interventions and parent education and training before the use of medication for maladaptive aggression at every stage of medication treatment, from diagnosis to maintenance to medication discontinuation. Conclusion Overall findings indicate that evidence-informed strategies for outpatient treatment of pediatric maladaptive aggression, guided by systematically derived expert opinions, are attainable. In light of the gap between the research literature and clinical practice, expert consensus opinion supports specific practices for optimal outpatient management in children and adolescents with severe and persistent behavioral difficulties.

The domain of Openness within the Five-Factor Model (FFM) has received inconsistent support as a source for maladaptive personality functioning, at least when the latter is confined to the disorders of personality included within the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR; APA, ). However, an advantage of the FFM relative to the DSM-IV-TR is that the former was developed to provide a reasonably comprehensive description of general personality structure. Rather than suggest that the FFM is inadequate because the DSM-IV-TR lacks much representation of Openness, it might be just as reasonable to suggest that the DSM-IV-TR is inadequate because it lacks an adequate representation of maladaptive variants of both high and low Openness. This article discusses the development and validation of a measure of these maladaptive variants, the Experiential Permeability Inventory.

Conspiracy theories can be treated as both rational narratives of the world as well as outcomes of underlying maladaptive traits. Here, we examined associations between belief in conspiracy theories and individual differences in personality disorders. An Internet-based sample (N=259) completed measures of belief in conspiracy theories and the 25 facets of the Personality Inventory for DSM-5 (PID-5). Preliminary analyses showed no significant differences in belief in conspiracy theories across participant sex, ethnicity, and education. Regression analyses showed that the PID-5 facets of Unusual Beliefs and Experiences and, to a lesser extent, Suspiciousness, significantly predicted belief in conspiracy theories. These findings highlight a role for maladaptive personality traits in understanding belief in conspiracy theories, but require further investigation.

A limited amount of research examines the short-term consequences of gang membership. Rarer, though, is the examination of more distal consequences of gang membership. This is unfortunate because it understates the true detrimental effect of gang membership across the life course, as well as the effects it may have on children of former gang members. Using data from the Rochester Youth Development Study, this work investigates the impact of gang membership in adolescence (ages 12-18) on a particularly problematic style of parenting, child maltreatment. Using discrete time survival analysis, this study finds that gang membership increases the likelihood of child maltreatment and this relationship is mediated by the more proximal outcomes of gang membership during adolescence, precocious transitions to adulthood.

Children chronically exposed to stress early in life are at increased risk for maladaptive outcomes, though the physiological mechanisms driving these effects are unknown. Cortisol reactivity was tested as a mediator of the relation between prenatal substance exposure and/or early adversity on adaptive and maladaptive outcomes. Data were drawn…

The emergence of L-DOPA-induced dyskinesia (LID) in patients with Parkinson disease (PD) could be due to maladaptive plasticity of corticostriatal synapses in response to L-DOPA treatment. A series of recent studies has revealed that LID is associated with marked morphological plasticity of striatal dendritic spines, particularly cell type-specific structural plasticity of medium spiny neurons (MSNs) in the striatum. In addition, evidence demonstrating the occurrence of plastic adaptations, including aberrant morphological and functional features, in multiple components of cortico-basal ganglionic circuitry, such as primary motor cortex (M1) and basal ganglia (BG) output nuclei. These adaptations have been implicated in the pathophysiology of LID. Here, we briefly review recent studies that have addressed maladaptive plastic changes within the cortico-BG loop in dyskinetic animal models of PD and patients with PD. PMID:28066191

Gambling Disorder (GD) is an addictive disorder resulting in significant impairment in occupational and social functioning. The aim of the present study was to investigate the relationship of GD risk to adaptive and maladaptive personality dimensions in a sample of nonreferred Italian gamblers. The authors found the risk for GD to show significant associations with the Openness and Conscientiousness scales of the Big Five Inventory (BFI); however, these effects were not significant after controlling for alcohol and drug use. GD risk showed significant associations with the Detachment and Antagonism domains of the Personality Inventory for DSM-5 (PID-5), as well as with the PID-5 facet scales of Hostility, Callousness, Deceitfulness, Manipulativeness, Irresponsibility, and (low) Rigid Perfectionism, even when controlling for alcohol and drug use. Maladaptive personality dispositions may serve as risk factors for pathological gambling, even beyond their impact on frequently concomitant problems with alcohol and other drugs.

People routinely make poor choices, despite knowledge of negative consequences. We found that individuals with Anorexia Nervosa, who make maladaptive food choices to the point of starvation, engaged the dorsal striatum more than healthy controls when making choices about what to eat, and that activity in fronto-striatal circuits was correlated with their actual food consumption in a meal the next day.

Based on previous studies, we hypothesized that the clinical phenomena of preoperative anxiety, emergence delirium, and postoperative maladaptive behavioral changes were closely related. We examined this issue using data obtained by our laboratory over the past 6 years. Only children who underwent surgery and general anesthesia using sevoflurane/O(2)/N(2)O and who did not receive midazolam were recruited. Children's anxiety was assessed preoperatively with the modified Yale Preoperative Anxiety Scale (mYPAS), emergence delirium was assessed in the postanesthesia care unit, and behavioral changes were assessed with the Post Hospital Behavior Questionnaire (PHBQ) on postoperative days 1, 2, 3, 7, and 14. Regression analysis showed that the odds of having marked symptoms of emergence delirium increased by 10% for each increment of 10 points in the child's state anxiety score (mYPAS). The odds ratio of having new-onset postoperative maladaptive behavior changes was 1.43 for children with marked emergence status as compared with children with no symptoms of emergence delirium. A 10-point increase in state anxiety scores led to a 12.5% increase in the odds that the child would have a new-onset maladaptive behavioral change after the surgery. This finding is highly significant to practicing clinicians, who can now predict the development of adverse postoperative phenomena, such as emergence delirium and postoperative behavioral changes, based on levels of preoperative anxiety.

Previous research has shown that both alcohol use and jealousy are related to negative relationship outcomes. Little work, however, has examined direct associations between alcohol use and jealousy. The current study was aimed to build upon existing research examining alcohol use and jealousy. More specifically, findings from current jealousy literature indicate that jealousy is a multifaceted construct with both maladaptive and adaptive aspects. The current study examined the association between maladaptive and adaptive feelings of jealousy and alcohol-related problems in the context of drinking to cope. Given the relationship between coping motives and alcohol-related problems, our primary interest was in predicting alcohol-related problems, but alcohol consumption was also investigated. Undergraduate students at a large Northwestern university (N=657) in the US participated in the study. They completed measures of jealousy, drinking to cope, alcohol use, and alcohol-related problems. Analyses examined associations between jealousy subscales, alcohol use, drinking to cope, and drinking problems. Results indicated that drinking to cope mediated the association between some, but not all, aspects of jealousy and problems with alcohol use. In particular, the more negative or maladaptive aspects of jealousy were related to drinking to cope and drinking problems, while the more adaptive aspects were not, suggesting a more complex view of jealousy than previously understood.

Understanding the role of maladaptive gaming-related cognitions may assist in screening and interventions for problematic gaming, including Internet gaming disorder (IGD). Cognitive-behavioural interventions that target specific cognitions related to gaming may be more effective than more general approaches that focus only on preoccupation with games. Although past research has identified cross-sectional associations between maladaptive cognitions and problematic gaming, it is less clear whether these cognitions can predict future changes in problematic gaming behaviour. The present study employed an 18-item measure of gaming cognition, assessing perfectionism, cognitive salience, regret, and behavioural salience, to investigate potential changes in problematic gaming over a 12-month period. The sample included 465 Australian adults (84% male, Mage=26.2years). It was found that individuals who became problematic gamers over 12months had higher baseline scores on perfectionism (d=1.20), cognitive salience (d=0.74) and regret (d=0.69) than those who remained non-problematic gamers. Problematic gamers who became non-problematic gamers had lower baseline perfectionism scores (d=0.62) than those who remained problematic gamers. Cognitive change accounted for an additional 28% of variance in problematic gaming scores beyond gender, age, and frequency of gaming. These findings suggest that maladaptive gaming-related cognitions could be screened in clinical trials to aid in case formulation and inform decisions on needed interventions to deliver optimal client outcomes.

Purpose Various gastrointestinal factors may contribute to maladaptive behavior in children with autism spectrum disorders (ASD). To determine the association between maladaptive behavior in children with ASD and gastrointestinal symptoms such as severity, intestinal microbiota, inflammation, enterocyte damage, permeability and absorption of opioid peptides. Methods This observational cross-sectional study compared children with ASD to healthy controls, aged 2-10 years. Maladaptive behavior was classified using the Approach Withdrawal Problems Composite subtest of the Pervasive Developmental Disorder Behavior Inventory. Dependent variables were gastrointestinal symptom severity index, fecal calprotectin, urinary D-lactate, urinary lactulose/mannitol excretion, urinary intestinal fatty acids binding protein (I-FABP) and urinary opioid peptide excretion. Results We did not find a significant difference between children with ASD with severe or mild maladaptive behavior and control subjects for gastrointestinal symptoms, fecal calprotectin, urinary D-lactate, and lactulose/mannitol ratio. Urinary opioid peptide excretion was absent in all children. Children with ASD with severe maladaptive behavior showed significantly higher urinary I-FABP levels compared to those with mild maladaptive behavior (p=0.019) and controls (p=0.015). Conclusion In our series, maladaptive behavior in ASD children was not associated with gastrointestinal symptoms, intestinal inflammation (no difference in calprotectin), microbiota (no difference in urinary D-lactate) and intestinal permeability (no difference in lactulose/manitol ratio). ASD children with severe maladaptive behavior have significantly more enterocyte damage (increased urinary I-FABP) than ASD children with mild maladaptive behavior and normal children. PMID:26770897
Introduction: To examine the extent to which cigarette smoking in adolescence is associated with maladaptive versus adaptive coping behaviors in adulthood. Method: The data came from a longitudinal study of New Zealand adolescents followed into adulthood at age 32 years. Using structural equation modeling (SEM), we examined the predictive association between daily smoking of cigarettes and symptoms of tobacco dependence from 18 to 26 years of age and later coping at age 32 years. We included pathways from childhood family disadvantage in addition to both adolescent stress–worry and adult coping in the model. Results: SEM revealed that cigarette smoking had a small but direct inverse effect on later adaptive coping (−.14) and a direct effect on maladaptive coping (.23) independent of the relationships between adolescent coping and stress–worry and later adult coping. Conclusions: The findings are consistent with the hypothesis that tobacco smoking may inhibit the development of self-efficacy or one’s ability to act with appropriate coping behaviors in any given situation.

Theoretical accounts suggest that an alteration in the brain's learning mechanisms might lead to overhasty inferences, resulting in psychotic symptoms. Here, we sought to elucidate the suggested link between maladaptive learning and psychosis. Ninety-eight healthy individuals with varying degrees of delusional ideation and hallucinatory experiences performed a probabilistic reasoning task that allowed us to quantify overhasty inferences. Replicating previous results, we found a relationship between psychotic experiences and overhasty inferences during probabilistic reasoning. Computational modelling revealed that the behavioral data was best explained by a novel computational learning model that formalizes the adaptiveness of learning by a non-linear distortion of prediction error processing, where an increased non-linearity implies a growing resilience against learning from surprising and thus unreliable information (large prediction errors). Most importantly, a decreased adaptiveness of learning predicted delusional ideation and hallucinatory experiences. Our current findings provide a formal description of the computational mechanisms underlying overhasty inferences, thereby empirically substantiating theories that link psychosis to maladaptive learning.

Introduction Cognitive theories of psychopathology have generally proposed that early experiences of childhood abuse and neglect may result in the development of early maladaptive self-schemas. Maladaptive core schemas are central in the development and maintenance of psychological symptoms in a schema-focused approach. Psychosocial dysfunction in individuals with psychological problems has been consistently found to be associated with symptom severity. However, till date, linkages between psychosocial functioning, early traumatic experiences and core schemas have received little attention. The aim of the present study was to explore the relations among maladaptive interpersonal styles, negative experiences in childhood and core self-schemas in non-clinical adults. Methods A total of 300 adults (58% women) participated in the study. The participants completed a socio-demographic questionnaire, Young Schema Questionnaire, Childhood Trauma Questionnaire and Interpersonal Style Scale. Results Hierarchical regression analyses revealed that the Disconnection and Rejection and Impaired Limits schema domains were significant antecedents of maladaptive interpersonal styles after controlling for demographic characteristics and childhood abuse and neglect. Associations of child sexual abuse with Emotionally Avoidant, Manipulative and Abusive interpersonal styles were mediated by early maladaptive schemas. Early maladaptive schemas mediated the relations of emotional abuse with Emotionally Avoidant and Avoidant interpersonal styles as well as the relations of physical abuse with Avoidant and Abusive interpersonal styles. Conclusion Interpersonal styles in adulthood are significantly associated with childhood traumatic experiences. Significant relations between early traumatic experiences and maladaptive interpersonal styles are mediated by early maladaptive schemas.

This study examined the relationships between life event stress, early maladaptive schemas, impulsivity and binge eating among adolescents and investigated the effects of early maladaptive schemas and impulsivity on the relationship between life event stress and binge eating. Specifically, we examined a moderated mediation model in which early maladaptive schemas mediated this relationship and impulsivity moderated the mediation effect. Life event stress, early maladaptive schemas, impulsivity and binge eating were investigated in a sample of 2172 seventh-, eighth- and tenth-grade middle and high school students (mean age = 14.55 years, standard deviation = 1.29). The results indicated that adolescents with greater life event stress, more early maladaptive schemas and higher levels of impulsivity displayed more severe binge eating. In addition, early maladaptive schemas mediated the relationship between life event stress and binge eating, while impulsivity moderated this relationship. Furthermore, impulsivity also moderated the mediation effect of early maladaptive schemas; as impulsivity levels increased, the strength of the association between life event stress and early maladaptive schemas increased. This study illustrates the importance of understanding individual differences and their effects on the relationship between life event stress and binge eating.

The study of neurobiological mechanisms underlying anxiety disorders has been shaped by learning models that frame anxiety as maladaptive learning. Pavlovian conditioning and extinction are particularly influential in defining learning stages that can account for symptoms of anxiety disorders. Recently, dynamic and task related communication between the basolateral complex of the amygdala (BLA) and the medial prefrontal cortex (mPFC) has emerged as a crucial aspect of successful evaluation of threat and safety. Ongoing patterns of neural signaling within the mPFC-BLA circuit during encoding, expression and extinction of adaptive learning are reviewed. The mechanisms whereby deficient mPFC-BLA interactions can lead to generalized fear and anxiety are discussed in learned and innate anxiety. Findings with cross-species validity are emphasized.

The literature on identity formation in individuals from socially devalued racial and ethnic groups in the United States is summarized. Implications are discussed for a particular segment of at-risk adolescents--those in foster care residential group homes--who have received little published attention. The majority, in large urban centers, are African-American or Latino. These young people bear a disproportionate burden of such societal problems as unintended pregnancy and childbearing, academic underachievement and early educational discontinuation, substance abuse, and, ultimately, homelessness and more individually and socially costly forms of dependency (criminal justice, welfare, or mental health systems). It is postulated that their social maladaptation is reflective of identity disturbances created by the negative images of African-Americans and Latinos perpetuated by the dominant society and unfiltered by optimal parental racial socialization.

Narcissism is a multifaceted construct that is inconsistently defined and assessed between clinical psychology and social-personality psychology. The purpose of the present study was to examine the similarities and differences in the cognitive schemas underlying various forms of narcissism. This was accomplished by examining the associations of normal and pathological forms of narcissism with the early maladaptive schemas. The results showed important similarities in these associations (e.g., all of the narcissism scales were positively associated with the entitlement schema) as well as differences (e.g., vulnerable narcissism was the only form of narcissism that was positively associated with subjugation). Discussion focuses on the implications of these results for the ways in which individuals with these forms of narcissism perceive and navigate their social environments.

Evolutionary traps are severe cases of behavioral maladaptation that occur when, due to human activity, the cues animals use to guide their behavior become uncoupled from their fitness consequences. The result is that animals can prefer the most dangerous resources or behaviors, even when better options are available. Traps are increasingly common and represent a significant wildlife conservation problem. Understanding of the more proximate sensory-cognitive mechanisms underpinning traps remains poor, which highlights the need for interdisciplinary and collaborative approaches to investigating traps. Key to advancing basic trap theory and its conservation applications will be the development of appropriate and tractable model systems to investigate the mechanisms that cause traps within species, and how mechanisms vary across species.

Settlement from the plankton ends the major dispersive stage of life for many marine organisms and exposes them to intense predation pressure in juvenile habitats. This predation mortality represents a life-history bottleneck that can determine recruitment success. At the level of individual predator-prey interactions, prey survival depends upon behavior, specifically how behavior affects prey conspicuousness and evasive ability. We conducted an experiment to identify behavioral traits and performance levels that are important determinants of which individuals survive or die soon after settlement. We measured a suite of behavioral traits on late stage, pre-settlement Ward's damsel (Pomacentrus wardi) collected using light traps. These behavioral traits included two measures of routine swimming (indicators of conspicuousness) and eight measures of escape performance to a visual startle stimulus. Fish were then released onto individual patch reefs, where divers measured an additional behavioral trait (boldness). We censused each patch reef until approximately 50% of the fish were missing (~24 h), which we assumed to be a result of predation. We used classification tree analysis to discriminate survivors from fish presumed dead based on poor behavioral performance. The classification tree revealed that individuals displaying the maladaptive combination of low escape response speed, low boldness on the reef, and high routine swimming speed were highly susceptible to predation (92.4% with this combination died within 24 h). This accounted for 55.2% of all fish that died. Several combinations of behavioral traits predicted likely survival over 24 h, but there was greater uncertainty about that prediction than there was for fish that were predicted to die. Thus maladaptive behavioral traits were easier to identify than adaptive traits.

Maladaptive perfectionism and perceived incompetence are two factors associated with disordered eating. In this study, we examined whether perceived incompetence moderated the relationship between maladaptive perfectionism and disordered eating. Three hundred fifteen college women completed surveys assessing eating habits and levels of perceived incompetence and perfectionism. Results supported a moderating effect of perceived incompetence such that as levels of perceived incompetence increased, the relationship between maladaptive perfectionism and disordered eating became increasingly strong. These results imply that clinicians may want to focus efforts on helping clients learn to set healthy goals and improve their perception of competence in life domains.

Tinnitus is a phantom auditory sensation that reduces quality of life for millions of people worldwide, and for which there is no medical cure. Most cases of tinnitus are associated with hearing loss caused by ageing or noise exposure. Exposure to loud recreational sound is common among the young, and this group are at increasing risk of developing tinnitus. Head or neck injuries can also trigger the development of tinnitus, as altered somatosensory input can affect auditory pathways and lead to tinnitus or modulate its intensity. Emotional and attentional state could be involved in the development and maintenance of tinnitus via top-down mechanisms. Thus, military personnel in combat are particularly at risk owing to combined risk factors (hearing loss, somatosensory system disturbances and emotional stress). Animal model studies have identified tinnitus-associated neural changes that commence at the cochlear nucleus and extend to the auditory cortex and other brain regions. Maladaptive neural plasticity seems to underlie these changes: it results in increased spontaneous firing rates and synchrony among neurons in central auditory structures, possibly generating the phantom percept. This Review highlights the links between animal and human studies, and discusses several therapeutic approaches that have been developed to target the neuroplastic changes underlying tinnitus.

Tinnitus is a phantom auditory sensation that reduces quality of life for millions worldwide and for which there is no medical cure. Most cases are associated with hearing loss caused by the aging process or noise exposure. Because exposure to loud recreational sound is common among youthful populations, young persons are at increasing risk. Head or neck injuries can also trigger the development of tinnitus, as altered somatosensory input can affect auditory pathways and lead to tinnitus or modulate its intensity. Emotional and attentional state may play a role in tinnitus development and maintenance via top-down mechanisms. Thus, military in combat are particularly at risk due to combined hearing loss, somatosensory system disturbances and emotional stress. Neuroscience research has identified neural changes related to tinnitus that commence at the cochlear nucleus and extend to the auditory cortex and brain regions beyond.

Early maladaptive schemas (EMSs) are cognitive patterns resulting from unmet core emotional needs in childhood that have been linked to the development of psychopathology. As depression is a multifaceted phenomenon, we hypothesized that specific dysphoric symptoms would be predicted by different EMSs. Four hundred and fifty-six participants completed a measure of EMSs (Young Schema Questionnaire) and reported on the severity of the symptoms of criterion A for major depression in DSM-IV during the occurrence of a dysphoric episode in the previous 12 months. A series of stepwise multiple regression analyses were performed to investigate the predictive power of the EMSs for the severity of each specific depressive symptom. When controlling for gender and current levels of depression, specific symptoms were predicted by different EMSs: sadness by Negativity/Pessimism; anhedonia by Failure; self-harm by Emotional Deprivation and Vulnerability to Harm or Illness; worthlessness by Failure and Negativity/Pessimism; psychomotor retardation/restlessness by Vulnerability to Harm or Illness and Entitlement/Grandiosity; and poor concentration by Insufficient Self-Control/Self-Discipline. The more physical symptoms of fatigue, insomnia/hypersomnia, and appetite loss/appetite gain were not predicted by any of the EMSs. Although the cross-sectional design of the study does not allow for conclusions about the direction of effects, results suggest that depression is not a unitary phenomenon and provide a possible explanation for previous inconsistent findings.

Environmental stressors induce coping strategies in the majority of individuals. The stress response, involving the activation of the hypothalamic-pituitary-adrenocortical axis and the consequent release of corticosteroid hormones, is indeed aimed at promoting metabolic, functional, and behavioral adaptations. However, behavioral stress is also associated with fast and long-lasting neurochemical, structural, and behavioral changes, leading to long-term remodeling of glutamate transmission, and increased susceptibility to neuropsychiatric disorders. Of note, early-life events, both in utero and during the early postnatal life, trigger reprogramming of the stress response, which is often associated with loss of stress resilience and ensuing neurobehavioral (mal)adaptations. Indeed, adverse experiences in early life are known to induce long-term stress-related neuropsychiatric disorders in vulnerable individuals. Here, we discuss recent findings about stress remodeling of excitatory neurotransmission and brain morphology in animal models of behavioral stress. These changes are likely driven by epigenetic factors that lie at the core of the stress-response reprogramming in individuals with a history of perinatal stress. We propose that reprogramming mechanisms may underlie the reorganization of excitatory neurotransmission in the short- and long-term response to stressful stimuli. PMID:27057367

The objective of the present study was to investigate the role played by early maladaptive schemas (EMS) on male sexual functioning and clarify the way these nuclear cognitive structures discriminate men with and without sexual dysfunction. A total of 242 men participated in the study (a community sample of 200 men and a clinical sample of 42 men with a DSM-IV diagnosis of sexual dysfunction). The community sample was divided into a control group (n=147) and a sub-clinical group (n=53), according to the cutoff scores of the International Index of Erectile Dysfunction (Rosen et al., 1997). All participants completed a set of measures assessing EMS (Young & Brown, 1989), sexual functioning (Rosen et al., 1997), psychopathology (Derogatis & Spencer, 1982), and cognitive schemas activated in hypothetical unsuccessful sexual situations (Nobre & Pinto-Gouveia, 2009a). Findings supported the hypothesis of a typical cognitive pattern in men with sexual difficulties. After controlling for psychopathology, men with sexual dysfunction reported more dependence/incompetence EMS and activated more difference, helpless, and particularly incompetence schemas in hypothetical unsuccessful sexual situations, in comparison to sexually healthy men. These results have important therapeutic implications for sex therapy.

Neuromodulatory effects of non-invasive brain stimulation (NIBS) have been extensively studied in chronic pain. A hypothetic mechanism of action would be to prevent or revert the ongoing maladaptive plasticity within the pain matrix. In this review, the authors discuss the mechanisms underlying the development of maladaptive plasticity in patients with chronic pain and the putative mechanisms of NIBS in modulating synaptic plasticity in neuropathic pain conditions.

Social-cognitive theories of aggression postulate that individuals who perpetrate aggression are likely to have high levels of maladaptive cognitive schemas that increase risk for aggression. Indeed, recent research has begun to examine whether early maladaptive schemas may increase the risk for aggression. However, no known research has examined this among individuals in substance use treatment, despite aggression and early maladaptive schemas being more prevalent among individuals with a substance use disorder than the general population. Toward this end, we examined the relationship between early maladaptive schemas and aggression in men in a residential substance use treatment facility (N = 106). Utilizing pre-existing patient records, results demonstrated unique associations between early maladaptive schema domains and aggression depending on the type of aggression and schema domain examined, even after controlling for substance use, antisocial personality, age, and education. The Impaired Limits domain was positively associated with verbal aggression, aggressive attitude, and overall aggression, whereas the Disconnection and Rejection domain was positively associated with physical aggression. These findings are consistent with social-cognitive models of aggression and advance our understanding of how early maladaptive schemas may influence aggression. The implications of these findings for future research are discussed.

The current study was designed to evaluate: (a) whether an 8-week psychoeducational intervention can reduce maladaptive weight-management practices in women (University females, N=24) with sub-clinical levels of eating pathology; and (b) whether its implementation reduces the risk of developing more severe eating pathology across time. Participants were randomly assigned to an experimental (EX) group or a self-monitoring control (SMC) group. Statistically significant changes on measures of eating pathology, including the Eating Attitudes Test-26 [Garner, D. M., Olmsted, M. P., Bohr, Y., & Garfinkel, P. (1982). The Eating Attitudes Test: psychometric features and clinical correlates. Psychological Medicine, 12, 871-878]; Forbidden Food Survey [Ruggerio, L., Williamson, D. A., Davis, C. J., Schlundt, D. G., & Carey, M. P. (1988). Forbidden Food Survey: Measure of bulimic's anticipated emotional reactions to specific foods. Addictive Behaviors, 13, 267-274]; and Bulimia Test-Revised [Thelen, M. H., Farmer, J., Wonderlich, S., & Smith, M. (1991). A revision of the bulimia test: The BULIT-R. Journal of Consulting and Clinical Psychology, 3(1), 119-124] were observed, as were changes in body image, as measured by the Body Shape Questionnaire [Cooper, P. J., Taylor, M. J., Cooper, Z., & Fairburn, C. G. (1987). The development and validation of the body shape questionnaire. International Journal of Eating Disorders, 6(4), 485-494]. Additional significant between-group differences in eating behavior, as measured by daily meal records, were also seen. Participants in the EX group evidenced improvements in scores which were significantly different from those observed in the SMC group. Unfortunately, attrition limited the utility of follow up data.

Persistent error patterns sometimes develop when teaching new discriminations. These patterns can be adventitiously reinforced, especially during long periods of chance-level responding (including baseline). Such behaviors can interfere with learning a new discrimination. They can also disrupt already learned discriminations, if they re-emerge during teaching procedures that generate errors. We present an example of this process. Our goal was to teach a boy with intellectual disabilities to touch one of two shapes on a computer screen (in technical terms, a simple simultaneous discrimination). We used a size-fading procedure. The correct stimulus was at full size, and the incorrect-stimulus size increased in increments of 10 %. Performance was nearly error free up to and including 60 % of full size. In a probe session with the incorrect stimulus at full size, however, accuracy plummeted. Also, a pattern of switching between choices, which apparently had been established in classroom instruction, re-emerged. The switching pattern interfered with already-learned discriminations. Despite having previously mastered a fading step with the incorrect stimulus up to 60 %, we were unable to maintain consistently high accuracy beyond 20 % of full size. We refined the teaching program such that fading was done in smaller steps (5 %), and decisions to "step back" to a smaller incorrect stimulus were made after every 5-instead of 20-trials. Errors were rare, switching behavior stopped, and he mastered the discrimination. This is a practical example of the importance of designing instruction that prevents adventitious reinforcement of maladaptive discriminated response patterns by reducing errors during acquisition.

Current treatment options for aortic aneurysms are suboptimal and their pathogenic mechanisms remain unclear. We propose the existence of a coordinated multi-node baroreceptor network that measures pressures at all vascular bifurcations and enables system-wide hemodynamic coordination and vasomotor regulation, in accordance with the principle of Bernoulli. While the presence of baroreceptors at bifurcations remains unknown, behavior at the level of systems predicts their existence, possibly as glomus cell derivatives. We propose that pressure misregistration among sensor nodes at different vascular bifurcations can precipitate feed-forward dysfunctions that promote thrombosis, inflammation, and vasomotor dysregulation resulting in aneurysm formation. One example of this phenomenon is aortic aneurysm, which is currently attributed to focal anatomic defects. As plaque builds in the infrarenal aorta, the increased blood velocity through this segment can widen the difference between pressures sensed at the iliac and the renal artery bifurcations. Due to the Bernoulli effect, this change creates an incorrect impression of reduced dynamic pressure at the kidneys. The erroneous perception of hypovolemia can induce a pernicious cycle of maladaptive adrenergia and associated coagulation and thrombosis, particularly in the infrarenal aortic segment as the body attempts to normalize renal perfusion. Atherosclerosis can further exacerbate baroreceptor dysfunction by interfering with sensor biology in feed-forward fashion. Hypertension may be a consequence as well as a source of atherosclerosis and aneurysm. The described system may have evolved when trauma-related hypovolemia was a far more prevalent driver of natural selection but may be rendered maladaptive in the setting of modern stressors. Failure to address these factors may explain the suboptimal long-term outcomes with current surgical and endovascular treatments for aneurysms. Implications for other potential sensor

It is common following stroke to focus early rehabilitation efforts on developing compensatory use of the less-affected body side. Here we used a rat model of focal cortical infarct to examine how motor skill acquisition with the less-affected (“intact”) forelimb influences sensorimotor function of the infarct-impaired forelimb and neural activity in peri-infarct cortex. Rats proficient in skilled reaching with one forelimb were given focal ischemic lesions in the contralateral sensorimotor cortex (SMC). Recovery in this forelimb was tested following a period of reach training focused on the intact forelimb or control procedures. Quantitative measures of the cumulatively expressed transcription factor, FosB/ΔFosB, were used to assay intact forelimb training effects on neuronal activity in remaining SMC of the infarcted hemisphere. Intact forelimb training worsened behavioral recovery in the impaired forelimb following unilateral focal ischemia. Furthermore, it decreased neuronal FosB/ΔFosB expression in layer II/III of peri-infarct SMC. These effects were not found in sham-operated rats trained sequentially with both forelimbs or in animals receiving bilateral forelimb training after unilateral infarcts. Thus, focused use of the intact forelimb has detrimental effects on recovery of impaired forelimb function following a focal ischemic injury and this is linked to reduced neuronal activation in remaining cortex. These results suggest that peri-infarct cortex becomes vulnerable to early post-stroke experience with the less-affected forelimb and that this experience may drive neural plasticity here in a direction that is maladaptive for functional outcome.

Local adaptation has often been documented in herbivorous insects. The potential for local maladaptation in phytophagous insects, however, has not been widely considered. I performed a two-generation reciprocal cross-transplant experiment with the generalist soft scale insect Saissetia coffeae (Hemiptera: Coccidae) on two common species of host plants in rain forest habitat in Costa Rica. In this system, S. coffeae showed significant local maladaptation at the level of the host species. Lineages originally collected from Witheringia enjoyed a strong advantage over those collected from Lomariopsis when both sets of lineages were placed on Lomariopsis; however, when both sets of lineages were raised on Witheringia, their fitnesses were statistically indistinguishable. While some aspects of the biology of S. coffeae may impair its ability to adapt to local selection pressures, scale insects are often locally adapted on fine spatial scales, and local maladaptation is therefore especially surprising. Other documented cases of local maladaptation in parasites appear to be due to evolution on the part of the host. The possibility that hosts or natural enemies may place local genotypes at a disadvantage, producing a pattern of local maladaptation, is one that deserves more consideration in the context of plant-insect interactions.

Rumination has consistently been found to be associated with the onset and duration of major depressive episodes. Little research, however, has examined factors that may weaken the association between maladaptive coping, such as rumination, and depressive symptoms. In three samples of participants, including 149 never-depressed adolescent girls, 41 never-depressed women, and 39 depressed women, we examined whether generally adaptive forms of coping interacted with generally maladaptive coping to predict depressive symptoms. Age-appropriate measures of coping and depression were administered to participants in each sample. In never-depressed females, maladaptive coping / rumination were more strongly related to depressive symptoms in the presence of lower levels of adaptive coping. The relation between depression and maladaptive coping / rumination was weaker in the context of higher levels of adaptive coping. In contrast, for the depressed females, we found main effects for rumination and adaptive coping, with higher levels of rumination and lower levels of adaptive coping being associated with higher levels of depressive symptoms. The present findings highlight how adaptive coping and maladaptive coping, including rumination, differentially relate to each other and depressive symptoms depending on individuals’ current depressive state.

Technology (i.e. tools, methods of cultivation and domestication, systems of construction and appropriation, machines) has increased the vital rates of humans, and is one of the defining features of the transition from Malthusian ecological stagnation to a potentially perpetual rising population growth. Maladaptations, on the other hand, encompass behaviours, customs and practices that decrease the vital rates of individuals. Technology and maladaptations are part of the total stock of culture carried by the individuals in a population. Here, we develop a quantitative model for the coevolution of cumulative adaptive technology and maladaptive culture in a 'producer-scrounger' game, which can also usefully be interpreted as an 'individual-social' learner interaction. Producers (individual learners) are assumed to invent new adaptations and maladaptations by trial-and-error learning, insight or deduction, and they pay the cost of innovation. Scroungers (social learners) are assumed to copy or imitate (cultural transmission) both the adaptations and maladaptations generated by producers. We show that the coevolutionary dynamics of producers and scroungers in the presence of cultural transmission can have a variety of effects on population carrying capacity. From stable polymorphism, where scroungers bring an advantage to the population (increase in carrying capacity), to periodic cycling, where scroungers decrease carrying capacity, we find that selection-driven cultural innovation and transmission may send a population on the path of indefinite growth or to extinction.

Background and aims The current study examined the mediating role of maladaptive perfectionism among parental psychological control, eating disorder symptoms, and exercise dependence symptoms by gender in habitual exercisers. Methods Participants were 348 Italian exercisers (n = 178 men and n = 170 women; M age = 20.57, SD = 1.13) who completed self-report questionnaires assessing their parental psychological control, maladaptive perfectionism, eating disorder symptoms, and exercise dependence symptoms. Results Results of the present study confirmed the mediating role of maladaptive perfectionism for eating disorder and exercise dependence symptoms for the male and female exercisers in the maternal data. In the paternal data, maladaptive perfectionism mediated the relationships between paternal psychological control and eating disorder and exercise dependence symptoms as full mediator for female participants and as partial mediator for male participants. Discussion Findings of the present study suggest that it may be beneficial to consider dimensions of maladaptive perfectionism and parental psychological control when studying eating disorder and exercise dependence symptoms in habitual exerciser.

Here we aimed to investigate the neuronal correlates of different coping styles in patients suffering from chronic tinnitus. Adaptive and maladaptive coping styles were determined in 85 tinnitus patients. Based on resting state EEG recordings, coping related differences in brain activity and connectivity were found. Maladaptive coping behavior was related to increases in subjective tinnitus loudness and distress, higher tinnitus severity and higher depression scores. EEG recordings demonstrated increased alpha activity over the left dorsolateral prefrontal cortex (DLPFC) and subgenual anterior cingulate cortex (sgACC) as well as increased connectivity in the default (i.e. resting state) network in tinnitus patients with a maladaptive coping style. Correlation analysis revealed that the changes in the DLPFC correlate primarily with maladaptive coping behavior, whereas the changes in the sgACC correlate with tinnitus severity and depression. Our findings are in line with previous research in the field of depression that during resting state a alpha band hyperconnectivity exists within the default network for patients who use a maladaptive coping style, with the sgACC as the dysfunctional node and that the strength of the connectivity is related to focusing on negative mood and catastrophizing about the consequences of tinnitus.

Objective To identify mechanisms of change in individuals with moderately severe obsessive-compulsive disorder (OCD) receiving cognitive therapy (CT). Method Thirty-six adults with OCD received CT over 24 weeks. At weeks 0, 4/6, 12, 16/18, and 24, independent evaluators assessed OCD severity, along with obsessive beliefs and maladaptive schemas. To examine mechanisms of change, we utilized a time-varying lagged regression model with a random intercept and slope. Results Perfectionism and certainty obsessive beliefs and maladaptive schemas related to dependency and incompetence significantly mediated (improved) treatment response. Conclusions Cognitive changes in perfectionism/certainty beliefs and maladaptive schemas related to dependency/incompetence precede behavioral symptom reduction for OCD patients. Targeting these mechanisms in future OCD treatment trials will emphasize the most relevant processes and facilitate maximum improvement. PMID:25544403

Recent developmental theorizing conceptualizes perfectionism as a mediator of the relation between intrusive parenting and psychopathology. Research addressing this hypothesis in relation to eating disorders (EDs), however, is lacking. This case-control study (a) examined mean-level differences between ED patients and normal controls in psychologically controlling parenting and perfectionism and (b) addressed the intervening role of perfectionism in associations between psychological control and ED symptoms, distinguishing between maladaptive and relatively more adaptive types of perfectionism. Hypotheses were examined in a sample of normal controls (N = 85) and a sample of ED patients (N = 60). Findings indicate that ED patients and bulimics in particular show elevated levels of paternal (but not maternal) psychological control and elevated levels of maladaptive perfectionism compared with normal controls. Mediation analyses show that maladaptive perfectionism is a significant intervening variable between parental psychological control and ED symptoms. Directions for future research on controlling parenting, perfectionism, and ED are outlined.

The five-factor model (FFM) of general personality functioning was derived originally from lexical studies of trait terms within the English language. Many studies have been conducted on the relationship of the FFM to personality disorder symptomatology but, as yet, no lexical study of the representation of maladaptive personality functioning within a language has been conducted. The current study identified the distribution of socially undesirable trait terms within each of the poles of the Big Five and compared this distribution to findings obtained with FFM personality disorder measures. The implications of the results for a FFM of personality disorders and for the FFM assessment of maladaptive personality functioning are discussed.

Background and Objectives Impulsive, maladaptive, and potentially self-damaging behaviors are a hallmark feature of borderline personality (BP) pathology. Difficulties with emotion regulation have been implicated in both BP pathology and maladaptive behaviors. One facet of emotion regulation that may be particularly important in the relation between BP pathology and urges for maladaptive behaviors is emotion differentiation. Methods Over one day, 84 participants high (n = 34) and low (n = 50) in BP pathology responded to questions regarding state emotions and urges to engage in maladaptive behaviors using handheld computers, in addition to a measure of emotion-related difficulties controlling impulsive behaviors. Results Results revealed that individuals high in BP pathology reported greater emotion-related impulsivity as well as daily urges to engage in maladaptive behaviors. However, the association between BP group and both baseline emotion-related impulsivity and daily urges for maladaptive behaviors was strongest among individuals who had low levels of positive emotion differentiation. Conversely, negative emotion differentiation did not significantly moderate the relationships between BP group and either emotion-related difficulties controlling impulsive behaviors or state urges for maladaptive behaviors. Limitations Limitations to the present study include the reliance upon an analogue sample and the relatively brief monitoring period. Conclusions Despite limitations, these results suggest that, among individuals with high BP pathology, the ability to differentiate between positive emotions may be a particularly important target in the reduction of maladaptive behaviors.

Previous research has shown that early maladaptive schemas (EMS) play an important role in substance use, depression, and anxiety. However, few studies have examined the role of EMS within the context of all three concurrently. The goal of this study was to determine the role of EMS in predicting symptoms of Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) among adults in residential treatment for substance dependence. We used pre-existing patient records of adults diagnosed with a substance use disorder from a residential substance use treatment facility (N=122). The EMS domains of disconnection and rejection and impaired limits were associated with symptoms of MDD and the domain of impaired autonomy and performance was associated with symptoms of GAD, even after controlling for age, gender, years of education, alcohol use, drug use, and symptoms of MDD (when predicting GAD) and GAD (when predicting MDD). Findings suggest that EMS may play an important role in comorbid mental health problems among men and women in residential substance use treatment. Continued treatment outcome research is needed to examine whether modification of EMS results in improved mental health and substance use outcomes.

The Early Maladaptive Schema Questionnaires Set for Children and Adolescents (SQS) was developed to assess early maladaptive schemas in children between the ages of 10 and 16 in Turkey. The SQS consists of five questionnaires that represent five schema domains in Young's schema theory. Psychometric properties (n = 983) and normative values (n = 2250) of SQS were investigated in children and adolescents between the ages of 10 and 16. Both exploratory and confirmatory factor analyses were performed. Results revealed 15 schema factors under five schema domains, with good fit indexes. A total of 14 schema factors were in line with Young's early maladaptive schemas. In addition to these factors, one new schema emerged: self-disapproval. Reliability analyses showed that SQS has high internal consistency and consistency over a 1-month interval. Correlations of SQS with the Adjective Check List (ACL), the Inventory of Parent and Peer Attachment (IPPA), the Symptom Assessment (SA-45) and the Young Schema Questionnaire (YSQ) were investigated to assess criterion validity, and the correlations revealed encouraging results. SQS significantly differentiated between children who have clinical diagnoses (n = 78) and children who have no diagnosis (n = 100). Finally, general normative values (n = 2,250) were determined for age groups, gender and age/gender groups. In conclusion, the early maladaptive schema questionnaires set for children and adolescents turned out to be a reliable and valid questionnaire with standard scores.Copyright © 2016 John Wiley & Sons, Ltd.

Brain edema formation and the ensuing brain damages are the major cause of high mortality and long term disability following the occurrence of ischemic stroke. In this process, oxygen and glucose deprivation and the resulting reperfusion injury play primary roles. In response to the ischemic insult, the neurovascular unit experiences both intracellular and extracellular edemas, associated with maladapted astrocytic plasticity. The astrocytic plasticity includes both morphological and functional plasticity. The former involves a reactive gliosis and the subsequent glial retraction. It relates to the capacity of astrocytes to buffer changes in extracellular chemical levels, particularly K+ and glutamate, as well as the integrity of the blood-brain barrier (BBB). The latter involves the expression and activity of a series of ion and water transport proteins. These molecules are grouped together around glial fibrillary acidic protein (GFAP) and water channel protein aquaporin 4 (AQP4) to form functional networks, regulate hydromineral balance across cell membranes and maintain the integrity of the BBB. Intense ischemic challenges can disrupt these capacities of astrocytes and result in their maladaptation. The maladapted astrocytic plasticity in ischemic stroke cannot only disrupt the hydromineral homeostasis across astrocyte membrane and the BBB, but also leads to disorders of the whole neurovascular unit. This review focuses on how the maladapted astrocytic plasticity in ischemic stroke plays the central role in the brain edema formation. PMID:27242440

Burnout is associated with poor mental and physical functioning and high costs for societies. Personality attributes may critically increase the risk of personal burnout. We specifically examined whether narcissism associates with personal burnout in a working population. We studied n=1461employees (mean age 41.3±9.4 years, 52% men) drawn from a random sample of a pharmaceutical company in Germany. All participants completed the personal burnout subscale of the Copenhagen Burnout Inventory and the Narcissistic Personality Inventory to assess maladaptive (entitlement/exploitativeness) and adaptive (leadership/authority) narcissism. In linear regression analysis, when mutually adjusting for the maladaptive and adaptive narcissism scales, higher adaptive narcissism was associated with lower burnout scores (ß=-0.04, p<0.05), whereas higher maladaptive narcissism was associated with higher burnout scores (ß=0.04, p<0.05). Additionally, younger age (ß=-0.07), female gender (ß=0.11), depressive symptoms (ß=0.42), sleep problems (ß=0.30), stress at work (ß=0.23) and at home (ß=0.09) were all independently associated with increased burnout scores (all p-values <0.01).Narcissistic personality attributes may play an important role in personal burnout. While maladaptive narcissism was associated with increased levels of burnout symptoms, adaptive narcissism was associated with fewer burnout symptoms.

Reactive oxygen species (ROS) produced by NADPH oxidase 2 (Nox2) function as key mediators of mechanotransduction during both physiological adaptation to mechanical load and maladaptive remodeling of the heart. This is despite low levels of cardiac Nox2 expression. The mechanism underlying the transition from adaptation to maladaptation remains obscure, however. We demonstrate that transient receptor potential canonical 3 (TRPC3), a Ca2+-permeable channel, acts as a positive regulator of ROS (PRROS) in cardiomyocytes, and specifically regulates pressure overload-induced maladaptive cardiac remodeling in mice. TRPC3 physically interacts with Nox2 at specific C-terminal sites, thereby protecting Nox2 from proteasome-dependent degradation and amplifying Ca2+-dependent Nox2 activation through TRPC3-mediated background Ca2+ entry. Nox2 also stabilizes TRPC3 proteins to enhance TRPC3 channel activity. Expression of TRPC3 C-terminal polypeptide abolished TRPC3-regulated ROS production by disrupting TRPC3-Nox2 interaction, without affecting TRPC3-mediated Ca2+ influx. The novel TRPC3 function as a PRROS provides a mechanistic explanation for how diastolic Ca2+ influx specifically encodes signals to induce ROS-mediated maladaptive remodeling and offers new therapeutic possibilities.

Coercive parent-child interaction models posit that an escalating cycle of negative, bidirectional interchanges influences the development of boys' externalizing problems and caregivers' maladaptive parenting over time. However, longitudinal studies examining this hypothesis have been unable to rule out the possibility that between-individual factors account for bidirectional associations between child externalizing problems and maladaptive parenting. Using a longitudinal sample of boys (N = 503) repeatedly assessed eight times across 6-month intervals in childhood (in a range between 6 and 13 years), the current study is the first to use novel within-individual change (fixed effects) models to examine whether parents tend to increase their use of maladaptive parenting strategies following an increase in their son's externalizing problems, or vice versa. These bidirectional associations were examined using multiple facets of externalizing problems (i.e., interpersonal callousness, conduct and oppositional defiant problems, hyperactivity/impulsivity) and parenting behaviors (i.e., physical punishment, involvement, parent-child communication). Analyses failed to support the notion that when boys increase their typical level of problem behaviors, their parents show an increase in their typical level of maladaptive parenting across the subsequent 6 month period, and vice versa. Instead, across 6-month intervals, within parent-son dyads, changes in maladaptive parenting and child externalizing problems waxed and waned in concert. Fixed effects models to address the topic of bidirectional relations between parent and child behavior are severely underrepresented. We recommend that other researchers who have found significant bidirectional parent-child associations using rank-order change models reexamine their data to determine whether these findings hold when examining changes within parent-child dyads.

Impaired functions of myocardial muscle cells in human and animals, is a primary defect associated with idiopathic dilated cardiomyopathy (DCM). The pathophysiological mechanisms implicated in the DCM are yet to be clarified and an effective therapy is still not available. The BIO TO-2 cardiomyopathic Syrian Hamsters (CMSHs) represent an animal model of idiopathic DCM. The aim of this study was to investigate the effect of long-term treatment (2 months) with propionyl-L-carnitine (PLC), coenzyme Q(10), omega-3 fatty acids and a combination of these three agents (formulation HS12607) on mechanical properties and acto-myosin crossbridges (CBs) kinetics of left ventricular (LV) papillary muscle from control and treated 10 month old BIO TO-2 CMSHs. Isometric and isotonic contractile properties of isolated papillary muscle from control and treated CMSHs were investigated, and acto-myosin CB number, force and kinetics were calculated using Huxley's equations. Mechanical parameter values were higher in treated than in control hamsters, particularly when substances were administered together in a coformulation (HS12607). Compared to control, HS12607-treated papillary muscles showed a significant increase of maximum peak isometric tension (P(o)) (30.06 +/- 4.91 vs. 19.74 +/- 5.00 mN/mm(2)), maximum extent of muscle shortening (0.13 +/- 0.03 vs. 0.07 +/- 0.02 L/L(max)), maximum unloaded shortening velocity (1.18 +/- 0.24 vs. 0.53 +/- 0.13 L/L(max) s(-1)) and maximum peak of power output (5.52 +/- 1.61 vs. 1.58 +/- 0.83). The curvature of the hyperbolic force-velocity relationships did not differ between control and treated hamsters. When compared to controls, acto-myosin CB number increased in treated hamsters [(6.67 +/- 1.91) 10(10)/mm(2) vs. (3.55 +/- 2.08) 10(10)/mm(2)], whereas the unitary force of single CB was similar in control and treated animals. The peak value of the rate constant for CB attachment (f(1)) and detachment (g(2)) was higher in treated animals when
A number of studies have shown that phantom limb pain is associated with plastic changes along the neuraxis, with a close correlation between changes in the cortical representation of the affected limb and phantom limb pain. Mechanisms underlying these maladaptive plastic changes are related to a loss of GABAergic inhibition, glutamate-mediated long-term potentiation-like changes and structural alterations such as axonal sprouting. These plastic changes and phantom limb pain seem to be more extensive when chronic pain precedes the amputation. Behavioral interventions, stimulation, feedback and pharmacological interventions that are designed to reverse these maladaptive memory traces and enhance extinction may be beneficial for the treatment and prevention of phantom limb pain.

To examine relationship between Eating Disorder Behaviors (EDB) and Early Maladaptive Schemas (EMS) across eating disorder (ED) subgroups. EMS and ED behaviors were measured by Young Schema Questionnaire and Eating Behavior Severity Scale, respectively, among patients diagnosed with Restrictive or Binge/purging Anorexia, or bulimia nervosa. Canonical component analysis showed significant association between ED behaviors and EMSs. Canonical factor-pairs (EDB and EMS) revealed specific associations between certain patterns of EDBs, including binge-purging and physical exercise, and certain patterns of maladaptive cognitive schema, including Emotional deprivation, Abandonment, Enmeshments, Subjugation, and Emotional inhibition. ED subgroups significantly differred between the EMS and EDB canonical factors, respectively. Our findings indicate that EMS and EDB are associated, and that the factors that potentially mediate the association differ significantly among ED subgroups. These results are consistent with the notion that EMSs play a specific role in the development and maintenance of ED behaviors.

Oxidative stress has been implicated in diabetes long-term complications. In this paper, we summarize the growing evidence suggesting that hyperglycemia-induced overproduction of superoxide by mitochondrial electron transport chain triggers a maladaptive response by affecting several metabolic and signaling pathways involved in the pathophysiology of cellular dysfunction and diabetic complications. In particular, it is our goal to describe physiological mechanisms underlying the mitochondrial free radical production and regulation to explain the oxidative stress derived from a high intracellular glucose concentration and the resulting maladaptive response that leads to a cellular dysfunction and pathological state. Finally, we outline potential therapies for diabetes focused to the prevention of mitochondrial oxidative damage. PMID:22253615

The Geographic Mosaic Theory of Coevolution predicts the occurrence of mosaics of interaction-mediated local adaptations and maladaptations. Empirical support to this prediction has come mostly from specialist interactions. In contrast, local adaptation is considered highly unlikely in generalist interactions. In this study, we experimentally test local adaptation in a generalist plant-pollinator geographic mosaic, by means of a transplant experiment in which plants coming from two evolutionary hotspots and two coldspots were offered to pollinators at the same four localities. Plants produced in the hotspots attracted more pollinators in all populations, whereas coldspot plants attracted fewer pollinators in all populations. Differences in adaptation were not related to genetic similarity between populations, suggesting that it was mainly due to spatial variation in previous selective regimes. Our experiment provides the first strong support for a spatially structured pattern of adaptation and maladaptation generated by a generalist free-living mutualism.

Previous research suggests that individuals abused as children are more likely to engage in risky sexual behavior during adulthood. The present study examined early maladaptive schemas as mediators of the child abuse-risky sexual behavior relationship among 653 college women. Self-report surveys assessed three forms of child abuse: Sexual, physical, and emotional, and assessed early maladaptive schemas within two domains: Disconnection/rejection and Other-Directedness. Disconnection/rejection schemas fully mediated the relation between child emotional abuse and number of sexual partners and partially mediated the relationship for sexual and physical abuse. However, when frequency of specific risky sexual acts (e.g., sex without contraception) was examined in the previous six months, only abandonment was a partial mediator. Implications for intervention and future research are discussed.

Body image inflexibility, the unwillingness to experience negative appearance-related thoughts and emotions, is associated with negative body image and eating disorder symptoms. The present study investigated whether body image inflexibility mediated the relationship between body image evaluation and maladaptive body image coping strategies (appearance-fixing and experiential avoidance) in a college and community sample comprising 156 females aged 18-51 years (M=22.76, SD=6.96). Controlling for recruitment source (college vs. community), body image inflexibility fully mediated the relationship between body image evaluation and maladaptive body image coping strategies. Results indicated that an unwillingness to experience negative appearance-related thoughts and emotions is likely responsible for negative body image evaluation's relationship to appearance-fixing behaviours and experiential avoidance. Findings support extant evidence that interventions that explicitly target body image inflexibility, such as Acceptance and Commitment Therapy, may have utility in treating body dissatisfaction in nonclinical populations.

This research investigated cultural factors and expectancies about eating and thinness among 93 African American women. Participants completed the Multigroup Ethnic Identity Measure (MEIM), Eating Expectancy Inventory and Thinness and Restricting Expectancy Inventory (EEI, TREI), and Eating Attitudes Test (EAT). The MEIM assessed affective and developmental aspects of one's own cultural identity, along with attitudes toward other groups. Further, expectancies that eating manages negative affect and thinness leads to life improvement were examined using the EEI and TREI. As hypothesized, those with strong expectancies about eating and thinness showed a significant negative relationship between ethnic identity and maladaptive eating patterns, whereas those with strong expectancies regarding thinness showed a significant positive relationship between other group orientation and maladaptive eating patterns. The results suggest one's identification with their own culture versus another culture is important to developing maladaptive eating patterns, if they feel that eating and thinness play a role in their affect management and life improvement. These factors may help understand who is more vulnerable to the development of disordered eating patterns, and therefore direct treatment among African American women.

This study examined the associations between maladaptive dependency-related schemas, posttraumatic stress disorder (PTSD) hyperarousal symptoms, and intimate-partner psychological and physical aggression in a sample of court-referred men (N = 174) participating in a domestic-abuser-intervention program. The men were largely African American; average age was 33.5 years. The extent to which hyperarousal symptoms moderated the association between dependency schemas and aggression was also examined. Maladaptive dependency-related schemas were positively associated with severe psychological, and mild and severe physical aggression perpetration. Hyperarousal symptoms were positively associated with mild and severe psychological aggression, and mild physical aggression perpetration. Multiple regression analyses showed a significant interaction for mild physical aggression: For those with high levels of hyperarousal symptoms, greater endorsement of maladaptive dependency schemas was associated with the perpetration of aggression (B = 0.98, p = .001). For those with low levels of hyperarousal symptoms, there was no association between dependency schemas and aggression (B = 0.04, ns). These findings suggest that focusing on problematic dependency and PTSD-hyperarousal symptoms in domestic-abuser-intervention programs may be helpful, and that examining related variables as possible moderators between dependency schemas and intimate aggression would be a fruitful area for future research.

Important changes were introduced concerning posttraumatic-stress disorder (PTSD) by the DSM-5 recognizing the role of negative emotions such as guilt and shame, but little evidence is yet available on their prevalence in population assessed by means of DSM-5 criteria. In this study we explored the rates of guilt and shame DSM-5 PTSD diagnostic symptoms among Italian survivors to a massive earthquake and their possible correlation with PTSD and maladaptive behaviors. 869 residents of the town of L'Aquila exposed to the earthquake of April 6th, 2009 were investigated by the Trauma and Loss Spectrum-Self Report (TALS-SR) with particular attention to guilt and shame feelings. DSM-5 symptomatological PTSD was reported by 41.7% of survivors, further 11.6% endorsed at least one guilt/shame symptoms, with significantly higher rates of endorsement were in PTSD respect to No-PTSD subjects, and in the subgroup with at least one maladaptive behavior respect to those with none. There was a significant main effects of PTSD and at least one guilt/shame symptom on TALS-SR symptomatological domains. Mean TALS-SR Maladaptive coping domain score appeared significantly higher in the subgroup with at least one guilt/shame symptom. Further study are needed to investigate guilt and shame feelings in survivors to a natural disaster.

Child sexual abuse is one of the most serious forms of abuse due to the psychological consequences that persist even into adulthood. Expressions of anger among child sexual abuse survivors remain common even years after the event. While child sexual abuse has been extensively studied, the expression of displaced aggression has been studied less. Some factors, such as the maladaptive early schemas, might account for this deficiency. The objective of this study was to analyze the relationships between child sexual abuse, displaced aggression, and these schemas according to gender and determine if these early schemas mediate the relationship between child sexual abuse and displaced aggression. A total of 168 Spanish subjects who were victims of child sexual abuse completed measures of childhood trauma, displaced aggression, and early maladaptive schemas. The results depict the relationship between child sexual abuse, displaced aggression, and early maladaptive schemas. Women scored higher than men in child sexual abuse, emotional abuse, disconnection or rejection and impaired autonomy. Mediational analysis found a significant mediation effect of disconnection or rejection on the relationship between child sexual abuse and displaced aggression; however, impaired autonomy did not mediate significantly.

Anomia, or impaired word retrieval, is the most widespread symptom of aphasia, an acquired language impairment secondary to brain damage. In the last decades, functional neuroimaging techniques have enabled studying the neural basis underlying anomia and its recovery. The present study aimed to explore maladaptive plasticity in persistent verb anomia, in three male participants with chronic nonfluent aphasia. Brain activation maps associated with semantic verb paraphasia occurring within an oral picture-naming task were identified with an event-related fMRI paradigm. These maps were compared with those obtained in our previous study examining adaptive plasticity (i.e., successful verb naming) in the same participants. The results show that activation patterns related to semantic verb paraphasia and successful verb naming comprise a number of common areas, contributing to both maladaptive and adaptive neuroplasticity mechanisms. This finding suggests that the segregation of brain areas provides only a partial view of the neural basis of verb anomia and successful verb naming. Therefore, it indicates the importance of network approaches which may better capture the complexity of maladaptive and adaptive neuroplasticity mechanisms in anomia recovery. PMID:27429808

The presence of maladaptive behaviors in young people with autism spectrum disorder (ASD) can significantly limit engagement in treatment programs, as well as compromise future educational and vocational opportunities. This study aimed to explore whether the Early Start Denver Model (ESDM) treatment approach reduced maladaptive behaviors in preschool-aged children with ASD in a community-based long day care setting. The level of maladaptive behavior of 38 children with ASD was rated using an observation-based measure on three occasions during the intervention: on entry, 12 weeks post-entry, and on exit (post-intervention) over an average treatment duration of 11.8 months. Significant reductions were found in children’s maladaptive behaviors over the course of the intervention, with 68% of children showing a treatment response by 12 weeks and 79% on exit. This change was accompanied by improvement in children’s overall developmental level as assessed by the Mullen scales of early learning, but not by significant changes on the Vineland Adaptive Behavior Scales-II or Social Communication Questionnaire. Replication with a larger sample, control conditions, and additional measures of maladaptive behavior is necessary in order to determine the specific factors underlying these improvements; however, the findings of the present study suggest that the ESDM program may be effective in improving not only core developmental domains, but also decreasing maladaptive behaviors in preschool-aged children with ASD.

Adaptive and Maladaptive Correlates of Repetitive Behavior and Restricted Interests in Persons with Down Syndrome and Developmentally-Matched Typical Children: A Two-Year Longitudinal Sequential Design
Evans, David W.; Kleinpeter, F. Lee; Slane, Mylissa M.; Boomer, K. B.
We examined the course of repetitive behavior and restricted interests (RBRI) in children with and without Down syndrome (DS) over a two-year time period. Forty-two typically-developing children and 43 persons with DS represented two mental age (MA) levels: “younger” 2–4 years; “older” 5–11 years. For typically developing younger children some aspects of RBRI increased from Time 1 to Time 2. In older children, these aspects remained stable or decreased over the two-year period. For participants with DS, RBRI remained stable or increased over time. Time 1 RBRI predicted Time 2 adaptive behavior (measured by the Vineland Scales) in typically developing children, whereas for participants with DS, Time 1 RBRI predicted poor adaptive outcome (Child Behavior Checklist) at Time 2. The results add to the body of literature examining the adaptive and maladaptive nature of repetitive behavior. PMID:24710387

Children chronically exposed to stress early in life are at increased risk for maladaptive outcomes, though the physiological mechanisms driving these effects are unknown. Cortisol reactivity was tested as a mediator of the relation between prenatal substance exposure and/or early adversity on adaptive and maladaptive outcomes. Data were drawn from a prospective longitudinal study of prenatal substance exposure (N = 860). Cortisol reactivity was assessed at age 11. Among African-Americans, prenatal substance exposure exerted an indirect effect through early adversity and cortisol reactivity to predict externalizing behavior, delinquency, and a positive student-teacher relationship at age 11. Decreased cortisol reactivity was related to maladaptive outcomes, and increased cortisol reactivity predicted better executive functioning and a more positive student-teacher relationship.

Conservation management often focuses on counteracting the adverse effects of human activities on threatened populations. However, conservation measures may unintentionally relax selection by allowing the 'survival of the not-so-fit', increasing the risk of fixation of maladaptive traits. Here, we report such a case in the critically-endangered Chatham Island black robin (Petroica traversi) which, in 1980, was reduced to a single breeding pair. Following this bottleneck, some females were observed to lay eggs on the rims of their nests. Rim eggs left in place always failed to hatch. To expedite population recovery, rim eggs were repositioned inside nests, yielding viable hatchlings. Repositioning resulted in rapid growth of the black robin population, but by 1989 over 50% of all females were laying rim eggs. We used an exceptional, species-wide pedigree to consider both recessive and dominant models of inheritance over all plausible founder genotype combinations at a biallelic and possibly sex-linked locus. The pattern of rim laying is best fitted as an autosomal dominant Mendelian trait. Using a phenotype permutation test we could also reject the null hypothesis of non-heritability for this trait in favour of our best-fitting model of heritability. Data collected after intervention ceased shows that the frequency of rim laying has strongly declined, and that this trait is maladaptive. This episode yields an important lesson for conservation biology: fixation of maladaptive traits could render small threatened populations completely dependent on humans for reproduction, irreversibly compromising the long term viability of populations humanity seeks to conserve.

In schema therapy (ST), early maladaptive schemas (EMS) are proposed to be the defining core of personality disorders. Adverse relational experiences in childhood are assumed to be the main cause for the development of EMS. The present study explored the links between perceived parental rearing behaviours, EMS, and personality disorder symptoms in a clinical sample (N=108). Results from mediation analyses suggest that EMS mediate the relationships between recalled parenting rearing behaviours and personality disorder symptoms. Findings give support to the theoretical model ST is based on.

Type D personality (the combination of negative affect and social inhibition) is associated with poor prognosis in cardiac patients. The current study aims to investigate the relationship between Type D and health-related behaviours. In a cross-sectional study, 200 healthy participants completed measures of Type D personality, and health-related behaviours. The results showed that Type D individuals engaged in more unhealthy behaviours including smoking, poor diet and lack of physical activity than non-Type D individuals. The association between Type D personality and maladaptive health behaviours may represent one mechanism to explain the link between Type D and ill-health.

Although conceptualizations of perfectionism have emphasized adaptive as well as maladaptive expressions of the construct, how these different dimensions or types of perfectionists might be reflected in comprehensive personality assessment instruments is unknown. An initial sample of 267 university students completed the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 2001), Millon Index of Personality Styles Revised (MIPS-R; Millon, 2004), and Almost Perfect Scale-Revised (Slaney, Mobley, Trippi, Ashby, & Johnson, 1996). Analyses indicated that dimensions and types of perfectionism were associated, in expected directions, with select scores on the MMPI-2 and MIPS-R.

The schema-focused model of occupational stress and work dysfunctions (Bamber & Price, 2006; Bamber, 2006) hypothesizes that individuals with EMS (unconsciously) gravitate toward occupations with similar dynamics and structures to the toxic early environments and relationships that created them. They subsequently re-enact these EMS and their associated maladaptive coping styles in the workplace. For most individuals, this results in 'schema healing', but for some individuals with more rigid and severe EMS, schema healing is not achieved and the structures and relationships of the workplace, together with the utilization of maladaptive coping styles, serve to perpetuate their EMS. The model hypothesizes that it is these individuals who are most vulnerable to developing occupational stress syndromesTo date, this model has been subjected to very little empirical investigation, so the main aim of this study was to address this gap in the literature by testing out some of its main assumptions and to provide empirical data, which would either support or reject the model using a population of health workers. Specifically, it was hypothesized that 'occupation-specific' EMS would be found in health workers from a range of different healthcare professions. It was also hypothesized that the presence of higher levels of EMS would be predictive of raised levels of occupational stress, psychiatric caseness and increased sickness absence in those individuals.A cross-sectional study design was employed and a total of 249 staff working within a NHS Trust, belonging to one of five occupational groups (medical doctors, nurses, clinical psychologists, IT staff and managers), participated in the study. All participants completed the Young Schema Questionnaire-Short Form (Young, 1998); the Maslach Burnout Inventory-Human Services Form (Maslach & Jackson, 1981), and the General Health Questionnaire-28-item version (Goldberg, 1978).

Microglia-induced maladaptive plasticity is being recognized as a major cause of deleterious self-sustaining pathological processes that occur in neurodegenerative and neuroinflammatory diseases. Microglia, the primary homeostatic guardian of the central nervous system, exert critical functions both during development, in neural circuit reshaping, and during adult life, in the brain physiological and pathological surveillance. This delicate critical role can be disrupted by neural, but also peripheral, noxious stimuli that can prime microglia to become overreactive to a second noxious stimulus or worsen underlying pathological processes. Among regulators of microglia, neuropeptides can play a major role. Their receptors are widely expressed in microglial cells and neuropeptide challenge can potently influence microglial activity in vitro. More relevantly, this regulator activity has been assessed also in vivo, in experimental models of brain diseases. Neuropeptide action in the central nervous system has been associated with beneficial effects in neurodegenerative and neuroinflammatory pathological experimental models. This review describes some of the mechanisms of the microglia maladaptive plasticity in vivo and how neuropeptide activity can represent a useful therapeutical target in a variety of human brain pathologies.

Maladaptive/irrational beliefs are significant cognitive vulnerability mechanisms in psychopathology. They are more likely to be associated with a genetic vulnerability marker under conditions of emotional distress when irrational beliefs are more salient. Therefore, in the current study we investigated the COMT Val(158)Met gene variation in relation to irrational beliefs, assuming this relationship depended on the level of emotional distress. Two hundred and sixty-seven genotyped volunteers were assessed for core/general maladaptive beliefs, as well as trait emotional distress. We focused on context-independent measures of irrational beliefs and emotional distress in the absence of a stressor. As expected, the relationship between COMT Val(158)Met and irrational beliefs depended on the level of emotional distress (f(2)=.314). The COMT Val(158)Met-irrationality association was significant only when individuals fell in the average to above average range of emotional distress. Furthermore, within this range the Met allele seemed to relate to higher irrational beliefs. These results were significant for overall irrational beliefs and its subtypes, but not for rational beliefs, the functional counterpart of irrationality. In light of the study's limitations, the results should be considered as preliminary. If replicable, these findings have potential implications for therapygenetics, changing the view that COMT Val(158)Met might be of greater relevance when treatment modality does not rely on cognitive variables.

Multi-host pathogens occur widely on both natural and agriculturally managed hosts. Despite the importance of such generalists, evolutionary studies of host-pathogen interactions have largely focused on tightly coupled interactions between species pairs. We characterized resistance in a collection of Arabidopsis thaliana hosts, including 24 accessions collected from the Midwest USA and 24 from around the world, and patterns of virulence in a collection of Pseudomonas syringae strains, including 24 strains collected from wild Midwest populations of A. thaliana (residents) and 18 from an array of cultivated species (non-residents). All of the non-resident strains and half of the resident strains elicited a resistance response on one or more A. thaliana accessions. The resident strains that failed to elicit any resistance response possessed an alternative type III secretion system (T3SS) that is unable to deliver effectors into plant host cells; as a result, these seemingly non-pathogenic strains are incapable of engaging in gene for gene interactions with A. thaliana. The remaining resident strains triggered greater resistance compared to non-resident strains, consistent with maladaptation of the resident bacterial population. We weigh the plausibility of two explanations: general maladaptation of pathogen strains and a more novel hypothesis whereby community level epidemiological dynamics result in adaptive dynamics favoring ephemeral hosts like A. thaliana.

The aim of the study was to conduct in-depth analyses of the lived experiences of the caregivers of dementia and their maladaptive thinking patterns and how their physical health was influenced and compromised. The main method used was interpretative phenomenological analysis and involved in-depth analysis of eight participants screened through homogenous purposive sampling. After taking written consent from the participants, semi-structured interviews were conducted to gather the data that were transcribed later on to carry out free textual analysis. The themes were generated from the transcripts through the funneling approach in order to arrive at the themes that were common, frequent, and reflected the experiences shared by the participants. The verification was done through peer review and rich thick description. The most significant themes regarding maladaptive cognitions were catastrophizing, overgeneralizing, and blaming, whereas fatigue and sleep disturbances were the most significant themes regarding physical health. The emergent themes point towards a need to devise indigenous therapeutic intervention for the caregivers of dementia in the Pakistani sociocultural context as the literature available on caregiving is quite scanty in our culture.

Decrements in one or more domains of psychosocial functioning (e.g., poor job performance, poor interpersonal relations) are commonly observed in psychiatric patients. The purpose of this study is to increase understanding of psychosocial functioning as a broad, multifaceted construct as well as its associations with both adaptive- and maladaptive-range personality traits in both nonclinical and psychiatric outpatient samples. The study was conducted in two phases. In Study 1, a nonclinical sample (N = 429) was administered seven psychosocial functioning and adaptive-range personality trait measures. In Study 2, psychiatric outpatients (N = 181) were administered the same psychosocial functioning measures, and maladaptive- as well as adaptive-range personality trait measures. Exploratory (both studies) and confirmatory (Study 2) factor analyses indicated a common three-factor, hierarchical structure of psychosocial functioning-Well Being, Social/Interpersonal Functioning, and Basic Functioning. These psychosocial functioning domains were closely--and differentially--linked with personality traits, especially strongly so in patients. Across samples, Well Being was associated with both Neuroticism/Negative Affectivity and Extraversion/Positive Affectivity, Social/Interpersonal Functioning was associated with both Agreeableness and Conscientiousness/Disinhibition, and Basic Functioning was associated with Conscientiousness/Disinhibition, although only modestly in the nonclinical sample. These relations generally were maintained even after partialing out current general dysphoric symptoms. These findings have implications for considering psychosocial functioning as an important third domain in a tripartite model together with personality and psychopathology.

The biotic and abiotic factors that facilitate or hinder species range expansions are many and complex. We examine the impact of two genetic processes and their interaction on fitness at expanding range edges: local maladaptation resulting from the presence of an environmental gradient and expansion load resulting from increased genetic drift at the range edge. Results from spatially explicit simulations indicate that the presence of an environmental gradient during range expansion reduces expansion load; conversely, increasing expansion load allows only locally adapted populations to persist at the range edge. Increased maladaptation reduces the speed of range expansion, resulting in less genetic drift at the expanding front and more immigration from the range center, therefore reducing expansion load at the range edge. These results may have ramifications for species being forced to shift their ranges because of climate change or other anthropogenic changes. If rapidly changing climate leads to faster expansion as populations track their shifting climatic optima, populations may suffer increased expansion load beyond previous expectations.

Research has shown that different maladaptive behavior categories may be maintained by different contingencies. We examined whether behavior categories or behavior topographies determine functional properties. The Questions about Behavioral Function with its five subscales (Attention, Escape, Nonsocial, Physical, and Tangible) was completed by direct care staff for one target behavior for each of 115 adults with varying degrees of intellectual disabilities. In the first step we examined the functional properties of three broad behavior categories (self-injurious behavior [SIB], stereotypic behavior, and aggressive/destructive behavior). Consistent with previous research stereotyped behaviors and SIB had significantly higher QABF Nonsocial (i.e., automatic positive reinforcement or self-stimulation) subscale scores than aggressive behavior, while none of the other subscales showed differences across the three behavior categories. Contrary to earlier studies, escape (or negative social reinforcement) was an important function not only for aggressive behavior, but also for SIB and stereotypies. A second analysis examined functional properties depending on two factors: the behavior topography (hitting vs. non-hitting behaviors) and their respective behavior category (SIB vs. aggression). SIB topographies had higher ratings than aggressive behavior on the QABF Nonsocial subscale. Of the five QABF subscales, only the subscale Nonsocial differed between categories of maladaptive behavior. Furthermore it was the behavior categories rather than the topographies that determined functional properties.

Stimuli that are more predictive of subsequent reward also function as better conditioned reinforcers. Moreover, stimuli attributed with incentive salience function as more robust conditioned reinforcers. Some theories have suggested that conditioned reinforcement plays an important role in promoting suboptimal choice behavior, like gambling. The present experiments examined how different stimuli, those attributed with incentive salience versus those without, can function in tandem with stimulus-reward predictive utility to promote maladaptive decision-making in rats. One group of rats had lights associated with goal-tracking as the reward-predictive stimuli and another had levers associated with sign-tracking as the reward-predictive stimuli. All rats were first trained on a choice procedure in which the expected value across both alternatives was equivalent but differed in their stimulus-reward predictive utility. Next, the expected value across both alternatives was systematically changed so that the alternative with greater stimulus-reward predictive utility was suboptimal in regard to primary reinforcement. The results demonstrate that in order to obtain suboptimal choice behavior, incentive salience alongside strong stimulus-reward predictive utility may be necessary; thus, maladaptive decision-making can be driven more by the value attributed to stimuli imbued with incentive salience that reliably predict a reward rather than the reward itself.

Objective The aim of this study was to examine the difference of early maladaptive schemas and parenting origins in opioid abusers and non-opioid abusers. Method The early maladaptive schemas and parenting origins were compared in 56 opioid abusers and 56 non-opioids abusers. Schemas were assessed by the Young Schema Questionnaire 3rd (short form); and parenting origins were assessed by the Young Parenting Inventory. Results Data were analyzed by multivariate analysis of variance (MANOVA). The analysis showed that the means for schemas between opioid abusers and non-opioid abusers were different. Chi square test showed that parenting origins were significantly associated with their related schemas. Conclusion The early maladaptive schemas and parenting origins in opioid abusers were more than non-opioid abusers; and parenting origins were related to their Corresponding schemas. PMID:22952522

Background: Children with intellectual disability (ID) are at risk for maladaptive development of social relatedness. Controversy exists whether Pervasive Developmental Disorder (PDD) takes precedence over disordered attachment for describing maladaptive social behaviour. The aim of this study was to assess the prevalence of disordered attachment…

Background: Post-traumatic stress disorder (PTSD) represents one of the most frequently psychiatric sequelae to earthquake exposure. Increasing evidence suggests the onset of maladaptive behaviors among veterans and adolescents with PTSD, with specific gender differences emerging in the latter. Aims of the present study were to investigate the relationships between maladaptive behaviors and PTSD in earthquake survivors, besides the gender differences in the type and prevalence of maladaptive behaviors and their association with PTSD. Methods: 900 residents of the town of L’Aquila who experienced the earthquake of April 6th 2009 (Richter Magnitude 6.3) were assessed by means of the Trauma and Loss Spectrum-Self Report (TALS-SR). Results: Significantly higher maladaptive behavior prevalence rates were found among subjects with PTSD. A statistically significant association was found between male gender and the presence of at least one maladaptive behavior among PTSD survivors. Further, among survivors with PTSD significant correlations emerged between maladaptive coping and symptoms of re-experiencing, avoidance and numbing, and arousal in women, while only between maladaptive coping and avoidance and numbing in men. Conclusions: Our results show high rates of maladaptive behaviors among earthquake survivors with PTSD suggesting a greater severity among men. Interestingly, post-traumatic stress symptomatology appears to be a better correlate of these behaviors among women than among men, suggesting the need for further studies based on a gender approach.

The study of habitat selection has long been influenced by the ideal free model, which maintains that young adults settle in habitat according to its inherent quality and the density of conspecifics within it. The model has gained support in recent years from the finding that conspecifics produce cues inadvertently that help prebreeders locate good habitat. Yet abundant evidence shows that animals often fail to occupy habitats that ecologists have identified as those of highest quality, leading to the conclusion that young animals settle on breeding spaces by means not widely understood. Here, we report that a phenomenon virtually unknown in nature, natal habitat preference induction (NHPI), is a strong predictor of territory settlement in both male and female common loons (Gavia immer). NHPI causes young animals to settle on natal-like breeding spaces, but not necessarily those that maximize reproductive success. If widespread, NHPI might explain apparently maladaptive habitat settlement. PMID:23804619

Src homology 2 B adapter protein 1 (SH2B1) modulates signaling by a variety of ligands that bind to receptor tyrosine kinases or JAK-associated cytokine receptors, including leptin, insulin, growth hormone (GH), and nerve growth factor (NGF). Targeted deletion of Sh2b1 in mice results in increased food intake, obesity, and insulin resistance, with an intermediate phenotype seen in heterozygous null mice on a high-fat diet. We identified SH2B1 loss-of-function mutations in a large cohort of patients with severe early-onset obesity. Mutation carriers exhibited hyperphagia, childhood-onset obesity, disproportionate insulin resistance, and reduced final height as adults. Unexpectedly, mutation carriers exhibited a spectrum of behavioral abnormalities that were not reported in controls, including social isolation and aggression. We conclude that SH2B1 plays a critical role in the control of human food intake and body weight and is implicated in maladaptive human behavior.

Both maladaptive schemas (MS) and perfectionism have been associated with eating pathology. However, previous research has not examined these variables simultaneously and has not studied possible mediating relationships between MS and multidimensional perfectionism for body image concerns in eating disorder (ED) patients. Eighty-eight female ED patients completed the Young Schema Questionnaire, the Frost Multidimensional Perfectionism Scale, and the Body Attitude Test. Body image concerns were found to be positively related to Personal Standards (PS) and Evaluative Concerns (EC) perfectionism and all five schema domains. PS Perfectionism was positively associated with Disconnection, Other-directedness, and Overvigilance. EC Perfectionism was positively related to Disconnection, Impaired Autonomy, Other-directedness, and Overvigilance. Moreover, EC perfectionism was found to be a significant mediator in the relationship between the schema domains Impaired Autonomy and Overvigilance and body image concerns. These findings denote the importance to address both core beliefs and perfectionism in ED treatment.

Children with Smith-Magenis Syndrome (SMS) exhibit deficits in adaptive behavior but systematic studies using objective measures are lacking. This descriptive study assessed adaptive functioning in 19 children with SMS using the Vineland Adaptive Behavior Scales (VABS). Maladaptive behavior was examined through parent questionnaires and the Childhood Autism Rating Scale. Cognitive functioning was evaluated with an age-appropriate test. Children scored below average on VABS Communication, Daily Living Skills, and Socialization scales. Learning problems and hyperactivity scales on the Conner's Parent Rating Scale were elevated, and girls were more impulsive than boys. Stereotypic and self-injurious behaviors were present in all children. Cognitive functioning was delayed and consistent with communication and daily living skills, while socialization scores were higher than IQ.

Changes in body shape, fluctuating asymmetry (FA) and crypsis were compared among Atlantic salmon Salmo salar fry kept as controls in captivity and those released and subsequently recaptured in the wild according to a before-after-control-impact (BACI) design. Hatchery fish that survived in the wild became more cryptic and displayed a much lower incidence of fin erosion and of asymmetric individuals than control fish kept in captivity. Significant differences in body shape were also apparent, and survivors had longer heads, thicker caudal peduncles and a more streamlined body shape than hatchery controls as early as 20 days following stocking, most likely as a result of phenotypic plasticity and non-random, selective mortality of maladapted phenotypes. Hatchery-reared fish typically perform poorly in the wild and the results of this study indicate that this may be due to phenotypic mismatch, i.e. because hatcheries generate fish that are phenotypically mismatched to the natural environment.

There has been a increasing interest in understanding emotion regulation deficits in social anxiety disorder (SAD; e.g., Hofmann, Sawyer, Fang, & Asnaani, 2012). However, much remains to be understood about the patterns of associations among regulation strategies in the repertoire. Doing so is important in light of the growing recognition that people's ability to flexibly implement strategies is associated with better mental health (e.g., Kashdan et al., 2014). Based on previous work (Aldao & Nolen-Hoeksema, 2012), we examined whether putatively adaptive and maladaptive emotion regulation strategies interacted with each other in the prediction of social anxiety symptoms in a sample of 71 participants undergoing CBT for SAD. We found that strategies interacted with each other and that this interaction was qualified by a three-way interaction with a contextual factor, namely treatment study phase. Consequently, these findings underscore the importance of modeling contextual factors when seeking to understand emotion regulation deficits in SAD.

This study examined the association among healthy and maladaptive aspects of interpersonal dependency and the management of pain in physical therapy outpatients. Ninety-eight patients were administered the Relationship Profile Test, West Haven-Yale Multidimensional Pain Inventory, and Pain Catastrophizing Scale. Results indicated that Destructive Overdependence was positively associated with an increased number of office visits, pain interference in one's daily life, pain severity, affective distress, and receiving positive partner responses. Dysfunctional Detachment was associated with affective distress, pain interference in one's daily life, and rumination about pain. Healthy Dependency was only associated with receiving distracting responses from others. Believing that a spouse/partner is supportive and caring about one's pain partially mediated the relationship between overdependency and pain interfering in one's life. These results support the clinical utility of assessing interpersonal dependency for its relationship to managing one's pain and health care utilization.

The current study prospectively examined trajectories of change in symptoms of irritability, hyperactivity, and social withdrawal, as well as predictors of such behaviors from age 9 to 18 for youths with autism spectrum disorder (ASD) and a comparison group with nonspectrum developmental delays. Children with more severe core features of autism had consistently higher irritability and hyperactivity scores over time than those with broader ASD and nonspectrum delays. Across all diagnoses, behaviors related to hyperactivity showed the greatest improvement. Social withdrawal worsened with age for a substantial proportion of youths with ASD but not for the nonspectrum comparison group. Compared with nonspectrum youths, children with ASD showed greater heterogeneity in trajectories for maladaptive behaviors. PMID:21905806

In human-altered environments, organisms may preferentially settle in poor-quality habitats where fitness returns are lower relative to available higher-quality habitats. Such ecological trapping is due to a mismatch between the cues used during habitat selection and the habitat quality. Maladaptive settlement decisions may occur when organisms are time-constrained and have to rapidly evaluate habitat quality based on incomplete knowledge of the resources and conditions that will be available later in the season. During a three-year study, we examined settlement decision-making in the long-distance migratory, open-habitat bird, the Red-backed shrike (Lanius collurio), as a response to recent land-use changes. In Northwest Europe, the shrikes typically breed in open areas under a management regime of extensive farming. In recent decades, Spruce forests have been increasingly managed with large-size cutblocks in even-aged plantations, thereby producing early-successional vegetation areas that are also colonised by the species. Farmland and open areas in forests create mosaics of two different types of habitats that are now occupied by the shrikes. We examined redundant measures of habitat preference (order of settlement after migration and distribution of dominant individuals) and several reproductive performance parameters in both habitat types to investigate whether habitat preference is in line with habitat quality. Territorial males exhibited a clear preference for the recently created open areas in forests with higher-quality males settling in this habitat type earlier. Reproductive performance was, however, higher in farmland, with higher nest success, offspring quantity, and quality compared to open areas in forests. The results showed strong among-year consistency and we can therefore exclude a transient situation. This study demonstrates a case of maladaptive habitat selection in a farmland bird expanding its breeding range to human-created open habitats in

Background Although the association between psychological trauma and early maladaptive schemas (EMS) is well established in the literature, no study to date has examined the relationship of EMS to PTSD and psychopathologies beyond depression and anxiety in a sample of adult survivors of interpersonal trauma. This information may be useful in helping our understanding on how to best treat interpersonal trauma. Objective We set out to investigate the association between EMS and common forms of psychopathology in a sample of women with a history of interpersonal trauma (n=82). We have hypothesised that survivors of interpersonal trauma will present with elevated EMS scores compared to a non-clinical control group (n=78). We have also hypothesised that unique schemas will be associated with unique psychopathological entities and that subgroups of interpersonal trauma survivors would be present in our sample, with subgroups displaying different profiles of schema severity elevations. Method Participants completed measures of trauma, psychopathology, dissociation, self-esteem, and the Young Schema Questionnaire. Results It was found that survivors of interpersonal trauma displayed elevated EMS scores across all 15 schemas compared to controls. Although the pattern of associations between different psychopathological features and schemas appears to be rather complex, schemas in the domains of Disconnection and Impaired Autonomy formed significant associations with all psychopathological features in this study. Conclusions Our findings support the usefulness of cognitive behavioural interventions that target schemas in the domains of Disconnection and Impaired Autonomy in an effort to modify existing core beliefs and decrease subsequent symptomatology in adult survivors of interpersonal trauma. Highlights of the article Interpersonal trauma survivors are distinguished primarily by a generalised elevation of their maladaptive schemas, rather than a unique schema profile

Personality disorders (PDs) can be partly captured by dimensional traits, a viewpoint reflected in the most recent Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) Alternative (Section III) Model for PD classification. The current study adds to the literature on the Alternative Model by examining the magnitude of genetic and environmental influences on 6 domains of maladaptive personality: negative emotionality, detachment, antagonism, disinhibition, compulsivity, and psychoticism. In a large, population-based sample (N = 2,293) of Norwegian male and female twin pairs, we investigated (a) if the domains demonstrated measurement invariance across gender at the phenotypic level, meaning that the relationships between the items and the latent factor were equivalent in men and women; and (b) if genetic and environmental influences on variation in these domains were equivalent across gender. Multiple group confirmatory factor modeling provided evidence that all 6 domain scale measurement models were gender-invariant. The best fitting biometric model for 4 of the 6 domains (negative emotionality, detachment, disinhibition, and compulsivity) was one in which genetic and environmental influences could be set invariant across gender. Evidence for sex differences in psychoticism was mixed, but the only clear evidence for quantitative sex differences was for the antagonism scale, with greater genetic influences found for men than women. Genetic influences across domains were moderate overall (19-37%), in line with previous research using symptom-based measures of PDs. This study adds to the very limited knowledge currently existing on the etiology of maladaptive personality traits. (PsycINFO Database Record

Fear-conditioning experiments in the anxiety disorders focus almost exclusively on passive-emotional, Pavlovian conditioning, rather than active-behavioral, instrumental conditioning. Paradigms eliciting both types of conditioning are needed to study maladaptive, instrumental behaviors resulting from Pavlovian abnormalities found in clinical anxiety. One such Pavlovian abnormality is generalization of fear from a conditioned danger-cue (CS+) to resembling stimuli. Though lab-based findings repeatedly link overgeneralized Pavlovian-fear to clinical anxiety, no study assesses the degree to which Pavlovian overgeneralization corresponds with maladaptive, overgeneralized instrumental-avoidance. The current effort fills this gap by validating a novel fear-potentiated startle paradigm including Pavlovian and instrumental components. The paradigm is embedded in a computer game during which shapes appear on the screen. One shape paired with electric-shock serves as CS+, and other resembling shapes, presented in the absence of shock, serve as generalization stimuli (GSs). During the game, participants choose whether to behaviorally avoid shock at the cost of poorer performance. Avoidance during CS+ is considered adaptive because shock is a real possibility. By contrast, avoidance during GSs is considered maladaptive because shock is not a realistic prospect and thus unnecessarily compromises performance. Results indicate significant Pavlovian-instrumental relations, with greater generalization of Pavlovian fear associated with overgeneralization of maladaptive instrumental-avoidance.

Although 96-100% of individuals with eating disorders (EDs) report insecure attachment, the specific mechanisms by which adult insecure attachment dimensions affect ED symptomatology remain to date largely unknown. This study examined maladaptive perfectionism as both a mediator and a moderator of the relationship between insecure attachment (anxiety and avoidance) and ED symptomatology in a clinical, treatment seeking, sample. Insecure anxious and avoidant attachment, maladaptive perfectionism, and ED symptomatology were assessed in 403 participants from three medium size specialized care centres for EDs in Italy. Structural equation modeling indicated that maladaptive perfectionism served as mediator between both insecure attachment patterns and ED symptomatology. It also interacted with insecure attachment to predict higher levels of ED symptoms - highlighting the importance of both insecure attachment patterns and maladaptive aspects of perfectionism as treatment targets. Multiple-group comparison analysis did not reveal differences across diagnostic groups (AN, BN, EDNOS) in mediating, main and interaction effects of perfectionism. These findings are consistent with recent discussions on the classification and treatment of EDs that have highlighted similarities between ED diagnostic groups and could be viewed through the lens of the Trans-theoretical Model of EDs. Implications for future research and intervention are discussed.

Background: University students confront psychological difficulties that can negatively influence their academic performance. The present study aimed to assess several areas of adaptive and maladaptive psychological functioning among university students who request counseling services. Method: One hundred eighty-four young female students seeking professional psychological help (Counseling seekers) and 185 young female students who have never asked for psychological help (Non-counseling seekers) were asked to complete the Adult Self-Report (ASR) to evaluate both their internalizing and externalizing problems through DSM-oriented scales as well as their adaptive functioning. Results: ANOVA results indicated worse psychological functioning for the students who sought counseling. They reported lower score in ASR Adaptive Functioning Scales (i.e., friends, jobs, family, education), and higher scores in DSM-oriented scales (i.e., Depressive, Anxiety, Somatic, Avoidant Personality, Attention Deficit/Hyperactivity symptoms) than the students who never asked psychological help. Furthermore, discriminant analysis successfully discriminated between the two groups of students on the basis of the ASR’s adaptive and DSM-oriented scales. Conclusion: The study findings could be useful to guide university counseling services in their screening activities as well as useful for clinical practice. PMID:28360880

Dysfunctional cognitions may be associated with unhealthy eating behaviors seen in individuals with obesity. However, dysfunctional cognitions commonly occur in individuals with poor mental health independently of weight. We examined whether individuals with morbid obesity differed with regard to dysfunctional cognitions when compared to individuals of normal weight, when mental health status was controlled for. 111 participants-53 with morbid obesity and 58 of normal weight-were assessed with the Mini-Mental State Examination, Young Schema Questionnaire, Cognitive Distortions Questionnaire, Depression, Anxiety and Stress Scale, and a Demographic and Clinical Questionnaire. Participants with morbid obesity showed higher scores in one (insufficient self-control/self-discipline) of 15 early maladaptive schemas and in one (labeling) of 15 cognitive distortions compared to participants of normal weight. The difference between groups for insufficient self-control/self-discipline was not significant when mental health status was controlled for. Participants with morbid obesity showed more severe anxiety than participants of normal weight. Our findings did not show clinically meaningful differences in dysfunctional cognitions between participants with morbid obesity or of normal weight. Dysfunctional cognitions presented by individuals with morbid obesity are likely related to their individual mental health and not to their weight.

The present study explores the validity of the Five Factor Dependency Inventory (FFDI), a measure of dependent personality traits from the perspective of the five factor model, examined across three separate samples and two studies. The first study examined the FFDI with respect to the traits assigned to assess dependent personality disorder (DPD) by the DSM-5 work group, two measures of DSM-IV-TR DPD and three measures of dependent traits, sampling 184 Mechanical Turk participants and 83 students (the latter oversampled for DPD features). Based on responses from an additional 137 students, the second study investigated the role of maladaptive agreeableness in dependency by examining the FFDI in relation to the interpersonal circumplex using three alternative measures. Discriminant validity was provided with respect to DSM-5 traits and the interpersonal circumplex. Incremental validity was provided with respect to the ability of the FFDI to account for variance within DPD measures beyond the variance explained by DSM-5 traits. Implications for the assessment of dependency and the proposed DSM-5 dimensional trait model are discussed.

This study investigates early maladaptive schemas (EMSs) in function of eating disorder (ED) subtypes (restrictive/bulimic) and the presence/absence of non-suicidal self-injury (NSSI). Female inpatients (N = 491) completed the Young Schema Questionnaire and the Self-Injury Questionnaire. The influence of ED subtype and the presence/absence of NSSI and their interaction on the EMS were investigated by means of a MANCOVA. The results showed main effects of ED subtype and the presence of NSSI on EMS. Patients with bulimia scored significantly higher on insufficient self-control and emotional deprivation, which are more related to cluster B compared with restrictive patients, whereas restrictive patients scored significantly higher on social undesirability, failure to achieve, subjugation and unrelenting standards compared with patients with bulimia that are more related to cluster C. Patients with ED with NSSI reported significantly higher EMS levels compared with patients without NSSI, suggesting that they could be of particular interest to benefit from schema therapy.

The present study investigated the validity of the two-factor solution of items selected from the Rumination Scale of the Response Style Questionnaire proposed by Treynor, Gonzalez, and Nolen-Hoeksema (2003). In the first part of this study we used samples of currently depressed (MDD), formerly depressed (FD), socially anxious (SP), and healthy control participants to examine whether the brooding and reflective pondering components differentiate participants with an anxiety disorder from participants with depression. In the second part of this study we examined whether these components of rumination were differentially related to cognitive biases in depression. Overall, the MDD group exhibited higher brooding scores than did all other groups; SP and FD groups did not differ from each other but obtained higher brooding scores than did the control participants. Only the MDD and the control groups differed on the reflective pondering factor. Importantly, brooding and reflective pondering were differentially related to cognitive biases. Specifically, the correlation between brooding/reflective pondering and memory bias was not significant when depressive symptoms were partialed out. The correlation between brooding and attentional bias for sad faces, however, remained significant even when current depressive symptoms were taken into account. In sum, our results support the formulation that rumination is composed of an adaptive reflective pondering factor and a maladaptive brooding factor.

Despite the important focus on the notion of cognitive distortions in the sexual offending area, the relevance of underlying cognitive schemas in sexual offenders has also been suggested. The aim of the present study was to investigate a potential relationship between Early Maladaptive Schemas (EMSs) and cognitive distortions in rapists. A total of 33 men convicted for rape completed the Bumby Rape Scale (BRS), the Young Schema Questionnaire - Short form-3 (YSQ-S3), the Brief Symptom Inventory (BSI), and the Socially Desirable Response Set Measure (SDRS-5). Results showed a significant relationship between the impaired limits schematic domain and the Justifying Rape dimension of the BRS. Specifically, after controlling for psychological distress levels and social desirability tendency, the entitlement/grandiosity schema from the impaired limits domain was a significant predictor of cognitive distortions related to Justifying Rape themes. Overall, despite preliminary, there is some evidence that the Young's Schema-Focused model namely the impaired limits dimension may contribute for the conceptualization of cognitive distortions in rapists and further investigation is recommended.

Music therapists use guided affect regulation in the treatment of mood disorders. However, self-directed uses of music in affect regulation are not fully understood. Some uses of music may have negative effects on mental health, as can non-music regulation strategies, such as rumination. Psychological testing and functional magnetic resonance imaging (fMRI) were used explore music listening strategies in relation to mental health. Participants (n = 123) were assessed for depression, anxiety and Neuroticism, and uses of Music in Mood Regulation (MMR). Neural responses to music were measured in the medial prefrontal cortex (mPFC) in a subset of participants (n = 56). Discharge, using music to express negative emotions, related to increased anxiety and Neuroticism in all participants and particularly in males. Males high in Discharge showed decreased activity of mPFC during music listening compared with those using less Discharge. Females high in Diversion, using music to distract from negative emotions, showed more mPFC activity than females using less Diversion. These results suggest that the use of Discharge strategy can be associated with maladaptive patterns of emotional regulation, and may even have long-term negative effects on mental health. This finding has real-world applications in psychotherapy and particularly in clinical music therapy. PMID:26379529

This qualitative study describes the lived experience of maladaptive daydreaming (MD), an excessive form of unwanted daydreaming that produces a rewarding experience based on a created fantasy of a parallel reality associated with a profound sense of presence. A total of 21 in-depth interviews with persons who self-identified as struggling with MD were analyzed utilizing a phenomenological approach. Interviewees described how their natural capacity for vivid daydreaming had developed into a time-consuming habit that resulted in serious dysfunction. The phenomenology of MD was typified by complex fantasized mental scenarios that were often laced with emotionally compensatory themes involving competency, social recognition, and support. MD could be activated if several requirements were met. Because social interaction seems to be incompatible with this absorbing mental activity, solitude was necessary. In addition, kinesthetic activity and/or exposure to evocative music also appeared to be essential features. Besides delivering a firsthand description of key characteristics of MD, the study also indicates that MD is associated with dysfunctionality for which participants expressed a substantial need for help.

The DSM-5 Section III model of personality disorders remains largely unexplored in older adults. More specifically, there is a need for further research on the generalizability of the five trait domains in old age. The development of a short operationalization to screen for maladaptive trait domains, the Personality Inventory for DSM-5 Brief Form (PID-5-BF), can stimulate the use of the alternative DSM-5 model in older adults by addressing the need for short instruments. The primary goal of this study was to examine the construct validity of the PID-5-BF by comparing its structural model and nomological network with the original PID-5 in terms of relations with domains of personality functioning and a gero-specific personality disorder indicator. A five-factor model was supported, but the domain Disinhibition was not replicated in the original PID-5, and some PID-5-BF items showed weak loadings. Nevertheless, the nomological network was similar and showed meaningful relations, supporting the use of the Brief PID-5 in older clinical samples.

This study applies the theoretical concepts of Rational Emotive Behavior Therapy (REBT; Ellis, 1962, 1994) to the analysis of functional and dysfunctional behaviour and emotions in the workplace and tests central assumptions of REBT in an organizational setting. We argue that Ellis' appraisal theory of emotion sheds light on some of the cognitive and emotional antecedents of emotional intelligence and emotionally intelligent behaviour. In an extension of REBT, we posit that adaptive emotions resulting from rational cognitions reflect more emotional intelligence than maladaptive emotions which result from irrational cognitions, because the former lead to functional behaviour. We hypothesize that semantically similar emotions (e.g. annoyance and rage) lead to different behavioural reactions and have a different functionality in an organizational context. The results of scenario experiments using organizational vignettes confirm the central assumptions of Ellis' appraisal theory and support our hypotheses of a correspondence between adaptive emotions and emotionally intelligent behaviour. Additionally, we find evidence that irrational job-related attitudes result in reduced work (but not life) satisfaction.

The current longitudinal study examined the effect of the transmission of maladaptive parenting strategies from grandmothers to adolescent mothers on children's subsequent development. Mexican-origin adolescent mothers (N = 204) participated in home interviews when the adolescent's child (89 boys, 60 girls) was 2, 3, 4, and 5 years old. Grandmothers' psychological control toward the adolescent mother was positively related to adolescents' potential for abuse 1 year later, which was subsequently positively related to adolescents' punitive discipline toward their young child. In addition, adolescent mothers' punitive discipline subsequently predicted greater externalizing problems and less committed compliance among their children. Adolescent mothers' potential for abuse and punitive discipline mediated the effects of grandmothers' psychological control on children's externalizing problems. Finally, adolescent mothers' potential for abuse mediated the effect of grandmothers' psychological control on adolescent mothers' punitive discipline. Results highlight the salience of long-term intergenerational effects of maladaptive parenting on children's behavior.

Abstract Clinical spinal cord injury (SCI) is accompanied by comorbid peripheral injury in 47% of patients. Human and animal modeling data have shown that painful peripheral injuries undermine long-term recovery of locomotion through unknown mechanisms. Peripheral nociceptive stimuli induce maladaptive synaptic plasticity in dorsal horn sensory systems through AMPA receptor (AMPAR) phosphorylation and trafficking to synapses. Here we test whether ventral horn motor neurons in rats demonstrate similar experience-dependent maladaptive plasticity below a complete SCI in vivo. Quantitative biochemistry demonstrated that intermittent nociceptive stimulation (INS) rapidly and selectively increases AMPAR subunit GluA1 serine 831 phosphorylation and localization to synapses in the injured spinal cord, while reducing synaptic GluA2. These changes predict motor dysfunction in the absence of cell death signaling, suggesting an opportunity for therapeutic reversal. Automated confocal time-course analysis of lumbar ventral horn motor neurons confirmed a time-dependent increase in synaptic GluA1 with concurrent decrease in synaptic GluA2. Optical fractionation of neuronal plasma membranes revealed GluA2 removal from extrasynaptic sites on motor neurons early after INS followed by removal from synapses 2 h later. As GluA2-lacking AMPARs are canonical calcium-permeable AMPARs (CP-AMPARs), their stimulus- and time-dependent insertion provides a therapeutic target for limiting calcium-dependent dynamic maladaptive plasticity after SCI. Confirming this, a selective CP-AMPAR antagonist protected against INS-induced maladaptive spinal plasticity, restoring adaptive motor responses on a sensorimotor spinal training task. These findings highlight the critical involvement of AMPARs in experience-dependent spinal cord plasticity after injury and provide a pharmacologically targetable synaptic mechanism by which early postinjury experience shapes motor plasticity.

Background: This study aimed to compare the effects of the schema along with mindfulness-based therapies in the psoriasis patients. Materials and Methods: This semi-experimental study with post- and pre-tests was conducted on the psoriasis patients in the Dermatology Clinic of the Isfahan Alzahra Hospital, Iran using the convenience sampling in 2014. The patients had a low general health score. The experimental groups included two treatment groups of schema-based (n = 8) and mindfulness (n = 8). Both groups received eight 90-min sessions therapy once a week; they were compared with 8 patients in the control group. To evaluate the psoriasis patients’ maladaptive schema, Young schema questionnaire was used. Data were analyzed through the covariance analysis test. Results: There was a significant difference between the schema-based therapy and mindfulness groups with the control group. There was also a significant difference between the schema-based therapy groups consisting of the defeated schema, dependence/incompetence schema, devotion schema, stubbornly criteria schema, merit schema, restraint/inadequate self-discipline schema, and the control group. Moreover, a significant difference existed between the maladaptive schema of mindfulness therapy group and the controls. There was a significant difference concerning the improvement of the psychopathologic symptoms between the mindfulness therapy group and the control group. Conclusions: This study showed similar effects of both the schema and mindfulness-based therapies on the maladaptive schemas in improving the psoriasis patients with the psychopathologic symptoms.

Growing evidence supports that the coping strategies that individuals utilize are a key predictor of distress following trauma. However, there is limited longitudinal research examining the relationship between psychological distress and coping over time, and even less research examining the possibility of reciprocal relationships between distress and coping, despite the fact that prior theoretical work posits such a relationship. The current study modeled the relationship between distress (PTSD and general distress) and maladaptive coping over time in a sample of 368 college women exposed to the mass shooting at Virginia Tech (VT). Participants completed web surveys regarding their distress, shooting-related coping, and shooting-related PTSD 2 months, 6 months, and 1 year following the shooting. They also completed measures of their psychological distress prior to the shooting as part of an unrelated study. A structural cross-lagged model with latent variables supported a reciprocal relationship between maladaptive coping and general psychological distress over time. In contrast, the cross-lagged model evaluating the relationship between PTSD and maladaptive coping supported that PTSD symptoms predicted coping over time, but there was no reciprocal relationship between coping and PTSD. Implications of the findings for future work examining adjustment following traumatic events are discussed.

Behavioral experience, in the form of skilled limb use, has been found to impact the structure and function of the central nervous system, affecting post-stroke behavioral outcome in both adaptive and maladaptive ways. Learning to rely on the less-affected, or non-paretic, body side is common following stroke in both humans and rodent models. In rats, it has been observed that skilled learning with the non-paretic forelimb following ischemic insult leads to impaired or delayed functional recovery of the paretic limb. Here we used a mouse model of focal motor cortical ischemic injury to examine the effects of non-paretic limb training following unilateral stroke. In addition, we exposed some mice to increased bimanual experience in the home cage following stroke to investigate the impact of coordinated dexterous limb use on the non-paretic limb training effect. Our results confirmed that skilled learning with the non-paretic limb impaired functional recovery following stroke in C56BL/6 mice, as it does in rats. Further, this effect was avoided when the skill learning of the non-paretic limb was coupled with increased dexterous use of both forelimbs in the home cage. These findings further establish the mouse as an appropriate model in which to study the neural mechanisms of recovery following stroke and extend previous findings to suggest that the dexterous coordinated use of the paretic and non-paretic limb can promote functional outcome following injury.

Bevezetés: Bár a sötéttől való félelem előfordulási gyakorisága gyermekkorban a legmagasabb, a jelenség fiatal felnőttkorban sem elhanyagolható. Célkitűzés: A sötéttől való félelem korai maladaptív sémákkal és kötődési minőséggel mutatott összefüggéseinek feltárása fiatal felnőttkorban, valamint a félelem nemi különbségeinek kimutatása. Módszer: A kérdőívcsomagot a félelem gyakoriságát és intenzitását mérő saját fejlesztésű kérdőív, a Young-féle Séma Kérdőív rövidített változata és a kötődés dimenzionális mérését szolgáló két mérőeszköz alkotta. A teszteket 120 egyetemista (közülük 68 nő) töltötte ki. Eredmények: A sötéttől való félelem gyakorisága az elkerülő, intenzitása a független és a szorongó kötődési minőséggel mutatott kapcsolatot. A sötéttől való félelem jellemzői számos korai maladaptív sémával összefüggést mutattak. A nők sötéttől való félelme a férfiakénál intenzívebb és gyakoribb volt. Következtetések: Az eredmények rámutatnak, hogy a sötéttől való félelem fokozott mértékének hátterében a személy kognitív jellegzetességeinek és kötődési mintázatának sajátosságai állnak. Ez a sötéttől való félelem lehetséges klinikai relevanciájára hívja fel a figyelmet. Orv. Hetil., 2014, 155(49), 1967–1972.

The aim of this study was to investigate cardiac functional status in pregnancy using a comprehensive approach taking into account the simultaneous changes in loading and geometry, as well as maternal age and anthropometric indices. This was a prospective cross-sectional study of 559 nulliparous pregnant women assessed at 4 time points during pregnancy and at 1 year postpartum. All women underwent conventional echocardiography and tissue Doppler velocities and strain rate analysis at multiple cardiac sites. Mean arterial pressure and total vascular resistance index significantly decreased (both P<0.001) during the first 2 trimesters of pregnancy and increased thereafter. Stroke volume index and cardiac index showed the opposite trend compared with mean arterial pressure and total vascular resistance index (both P<0.05). Myocardial and ventricular function were significantly enhanced in the first 2 trimesters but progressively declined thereafter. By the end of pregnancy, significant chamber diastolic dysfunction and impaired myocardial relaxation was evident in 17.9% and 28.4% of women, respectively, whereas myocardial contractility was preserved. There was full recovery of cardiac function at 1 year postpartum. Cardiovascular changes during pregnancy are thought to represent a physiological adaptation to volume overload. The findings of a drop in stroke volume index, impaired myocardial relaxation with diastolic dysfunction, and a tendency toward eccentric remodeling in a significant proportion of cases at term are suggestive of cardiovascular maladaptation to the volume-overloaded state in some apparently normal pregnancies. These unexpected cardiovascular findings have important implications for the management of both normal and pathological pregnancy states.

Rejection sensitivity (RS) refers to the tendency to anxiously expect, readily perceive, and overreact to experiences of possible rejection. RS is a clear risk factor for psychological maladaptation during early adolescence. However, there is growing evidence of significant heterogeneity in the psychological correlates of RS. To investigate when RS poses the greatest psychological risk during early adolescence, this study examines mutual best friendship involvement (or lack thereof) and the best friends' RS as potential moderators of the associations between RS and psychological difficulties. Participants were 150 7th grade students (58 boys; M age = 13.05 years) who nominated their best friends, and reported on their RS, social anxiety, and self-esteem. Results from a series of hierarchical multiple regression analyses indicated that mutual best friendship involvement and best friends' RS were both significant moderators when fear of negative evaluation (a type of social anxiety) served as the dependent variable. The association between RS and fear of negative evaluation was stronger for adolescents without mutual best friends than adolescents with mutual best friends. In addition, the association between RS and fear of negative evaluation was the strongest for adolescents whose best friends were highly rejection sensitive (relative to adolescents whose best friends were moderately or low in RS). Findings highlight the importance of considering best friendships in studies of RS and strongly suggest that, although having mutual best friendships may be protective for rejection sensitive adolescents, having a rejection sensitive best friend may exacerbate difficulties. The significance of friends in the lives of rejection sensitive adolescents is discussed as well as possible applied implications of the findings and study limitations.

Children of incarcerated mothers are at increased risk for social and emotional difficulties, yet few studies have investigated potential mechanisms of risk within this population. This research simultaneously examined the association of children’s experience of incarceration-specific risk factors (e.g., witness mother’s arrest) and environmental risks (e.g., low educational attainment) to children’s psychological maladaptation using a multi-informant design and a latent variable analytic approach. Participants were 117 currently incarcerated mothers (64.1% African American), their 151 children (53.6% boys, M age =9.8 years, range =6–12 years, 61.7% African American), and the 118 caregivers (74.8% female, 61.9% grandparents, 62.2% African American) of the children. Mothers, children, and caregivers each provided accounts of children’s experiences related to maternal incarceration and children’s internalizing and externalizing behavior problems. Mothers and caregivers each supplied information about 10 environmental risk factors. Findings from structural equation modeling indicate that children’s incarceration-specific risk experiences predict internalizing and externalizing behavior problems whereas the influence of environmental risks was negligible. Follow-up analyses examining the contribution of specific risks indicate that significant predictors differ by reporter and separate into effects of family incarceration history and direct experiences of maternal incarceration. Incarceration-specific experiences place children at higher risk for maladjustment than exposure to general environmental risk factors. These findings indicate the need to critically examine children’s exposure to experiences related to maternal incarceration and family incarceration history to help to clarify the multifaceted stressor of maternal incarceration.

Understanding adaptive genetic responses to climate change is a main challenge for preserving biological diversity. Successful predictive models for climate-driven range shifts of species depend on the integration of information on adaptation, including that derived from genomic studies. Long-lived forest trees can experience substantial environmental change across generations, which results in a much more prominent adaptation lag than in annual species. Here, we show that candidate-gene SNPs (single nucleotide polymorphisms) can be used as predictors of maladaptation to climate in maritime pine (Pinus pinaster Aiton), an outcrossing long-lived keystone tree. A set of 18 SNPs potentially associated with climate, 5 of them involving amino acid-changing variants, were retained after performing logistic regression, latent factor mixed models, and Bayesian analyses of SNP-climate correlations. These relationships identified temperature as an important adaptive driver in maritime pine and highlighted that selective forces are operating differentially in geographically discrete gene pools. The frequency of the locally advantageous alleles at these selected loci was strongly correlated with survival in a common garden under extreme (hot and dry) climate conditions, which suggests that candidate-gene SNPs can be used to forecast the likely destiny of natural forest ecosystems under climate change scenarios. Differential levels of forest decline are anticipated for distinct maritime pine gene pools. Geographically defined molecular proxies for climate adaptation will thus critically enhance the predictive power of range-shift models and help establish mitigation measures for long-lived keystone forest trees in the face of impending climate change.

Over the past decade, it has become increasingly evident that there are extensive bidirectional interactions between the body and its microbiota. These interactions are evident during stressful periods, where it is recognized that commensal microbiota community structure is significantly changed. Many different stressors, ranging from early life stressors to stressors administered during adulthood, lead to significant, community-wide differences in the microbiota. The mechanisms through which this occurs are not yet known, but it is known that commensal microbes can recognize, and respond to, mammalian hormones and neurotransmitters, including those that are involved with the physiological response to stressful stimuli. In addition, the physiological stress response also changes many aspects of gastrointestinal physiology that can impact microbial community composition. Thus, there are many routes through which microbial community composition might be disrupted during stressful periods. The implications of these disruptions in commensal microbial communities for host health are still not well understood, but the commensal microbiota have been linked to stressor-induced immunopotentiation. The role of the microbiota in stressor-induced immunopotentiation can be adaptive, such as when these microbes stimulate innate defenses against bacterial infection. However, the commensal microbiota can also lead to maladaptive immune responses during stressor-exposure. This is evident in animal models of colonic inflammation where stressor exposure increases the inflammation through mechanisms involving the microbiota. It is likely that during stressor exposure, immune cell functioning is regulated by combined effects of both neurotransmitters/hormones and commensal microbes. Defining this regulation should be a focus of future studies.

Patients with the early-onset Alzheimer's disease P117L mutation in the presenilin-1 gene (PS-1) present pathological hallmarks in the hippocampus, the frontal cortex and the basal ganglia. In the present work we determined by immunohistochemistry which brain regions were injured in the transgenic PS-1 P117L mice, in comparison to their littermates, the B6D2 mice. Furthermore, as these regions are involved in novelty detection, we investigated the behavior of these mice in tests for object and place novelty recognition. Limited numbers of senile plaques and neurofibrillary tangles were detected in aged PS-1 P117L mice in the CA1 only, indicating that the disease is restrained to an initial neuropathological stage. Western blots showed a change in PSD-95 expression (p=0.03), not in NR2A subunit, NR2B subunit and synaptophysin expressions in the frontal cortex, suggesting specific synaptic alterations. The behavioral tests repeatedly revealed, despite a non-significant preference for object or place novelty, maladaptive exploratory behavior of the PS-1 P117L mice in novel environmental conditions, not due to locomotor problems. These mice, unlike the B6D2 mice, were less inhibited to visit the center of the cages (p=0.01) and they continued to move excessively in the presence of a displaced object (p=0.021). Overall, the PS-1 P117L mice appear to be in an initial Alzheimer's disease-like neuropathological stage, and they showed a lack of reaction toward novel environmental conditions.

constraint. It may be that hypothyroidism is conserved in such areas because it may confer adaptive advantage in such marginal environments as an effect, as well as a cause, of underdevelopment. Hypothyroidism may limit energy requirements, fertility, and consumer population pressure in closed ecosystems that could otherwise be outstripped. Single factor intervention in a vertical health care program not sensitive to the fragile biologic balance and not part of a culture-sensitive development program might result in medical maladaptation.

A prospective longitudinal follow-up study (n = 59) of child and adolescent survivors of physical assaults and motor vehicle accidents assessed whether cognitive processes predicted posttraumatic stress symptomatology (PTSS) at 6 months posttrauma in this age group. In particular, the study assessed whether maladaptive posttraumatic appraisals mediated the relationship between initial and later posttraumatic stress. Self-report measures of PTSS, maladaptive appraisals, and other cognitive processes, as well as structured interviews assessing for acute stress disorder and posttraumatic stress disorder (PTSD), were completed at 2-4 weeks and 6 months posttrauma. PTSS and PTSD at 6 months were associated with maladaptive appraisals and other cognitive processes but not demographic or objective trauma severity variables. Only maladaptive appraisals were found to associate with PTSS/PTSD after partialing out initial symptoms/diagnosis and to mediate between initial and later PTSS. It was argued that, on this basis, maladaptive appraisals are involved in the development and maintenance of PTSS over time, whereas other cognitive processes (e.g., subjective threat, memory processes) may have an effect only in the acute phase. The implications of this study for the treatment of PTSS in youths are discussed.

Diabetes mellitus significantly increases the risk of heart failure, independent of coronary artery disease. The mechanisms implicated in the development of diabetic heart disease, commonly termed diabetic cardiomyopathy, are complex, but much of the impact of diabetes on the heart can be attributed to impaired glucose handling. It has been shown that the maladaptive nutrient-sensing hexosamine biosynthesis pathway (HBP) contributes to diabetic complications in many non-cardiac tissues. Glucose metabolism by the HBP leads to enzymatically-regulated, O-linked attachment of a sugar moiety molecule, β-N-acetylglucosamine (O-GlcNAc), to proteins, affecting their biological activity (similar to phosphorylation). In normal physiology, transient activation of HBP/O-GlcNAc mechanisms is an adaptive, protective means to enhance cell survival; interventions that acutely suppress this pathway decrease tolerance to stress. Conversely, chronic dysregulation of HBP/O-GlcNAc mechanisms has been shown to be detrimental in certain pathological settings, including diabetes and cancer. Most of our understanding of the impact of sustained maladaptive HBP and O-GlcNAc protein modifications has been derived from adipose tissue, skeletal muscle and other non-cardiac tissues, as a contributing mechanism to insulin resistance and progression of diabetic complications. However, the long-term consequences of persistent activation of cardiac HBP and O-GlcNAc are not well-understood; therefore, the goal of this timely review is to highlight current understanding of the role of the HBP pathway in development of diabetic cardiomyopathy.

The objectives of this study were to assess within-person hypotheses regarding temporal cognition-pain associations: (1) do morning pain flares predict changes in two afternoon adaptive and maladaptive pain-related cognitions, and (2) do these changes in afternoon cognitions predict changes in end-of-day pain reports, which in turn, carry over to predict next morning pain in individuals with fibromyalgia. Two hundred twenty individuals with fibromyalgia completed electronic assessments of pain intensity, pain catastrophizing, and pain coping efficacy three times a day for three weeks. Multilevel structural equation modeling established that afternoon catastrophizing and coping efficacy were parallel mediators linking late morning with end-of-day pain reports (controlling for afternoon pain), in line with prediction. Catastrophizing was a stronger mediator than coping efficacy. Moreover, afternoon cognitions and end-of-day pain reports served as sequential mediators of the relation between same-day and next-day morning pain. These findings align with assertions of cognitive-behavioral theories of pain that pain flares predict changes in pain both adaptive and maladaptive cognitions, which in turn, predict further changes in pain.

Stress responses entail neuroendocrine, autonomic, and behavioral changes to promote effective coping with real or perceived threats to one’s safety. While these responses are critical for the survival of the individual, adverse effects of repeated exposure to stress are widely known to have deleterious effects on health. Thus, a considerable effort in the search for treatments to stress-related CNS disorders necessitates unraveling the brain mechanisms responsible for adaptation under acute conditions and their perturbations following chronic stress exposure. This paper is based upon a symposium from the 2014 International Behavioral Neuroscience Meeting, summarizing some recent advances in understanding the effects of stress on adaptive and maladaptive responses subserved by limbic forebrain networks. An important theme highlighted in this review is that the same networks mediating neuroendocrine, autonomic, and behavioral processes during adaptive coping also comprise targets of the effects of repeated stress exposure in the development of maladaptive states. Where possible, reference is made to the similarity of neurobiological substrates and effects observed following repeated exposure to stress in laboratory animals and the clinical features of stress-related disorders in humans.

Despite often being considered equivalent affective states, shame and guilt have differential associations with problem gambling with only shame showing a strong positive association with problem gambling. However, little is known about the mechanisms underlying the shame-problem gambling association. Further, shame and guilt are associated with distinct coping strategies, with shame motivating maladaptive coping (e.g., avoidance, escape) and guilt motivating adaptive coping (e.g., taking corrective action). This study aimed to examine whether maladaptive coping motives for gambling mediate the relationship between shame, but not guilt, and gambling problems. Participants were 196 (126 male) regular gamblers who completed a same and guilt scale, the Problem Gambling Severity Index, and a modified Gambling Motives Questionnaire, which assessed individual motives to engage in gambling for coping, enhancement, or social reasons. Results indicated that coping motives for gambling fully mediated the relationship between shame and problem gambling severity, but did not mediate the association between guilt and problem gambling severity. Experiencing shame contributes to problem gambling as a result of gambling to cope with negative affect. Cultivating more adaptive strategies to cope with shame may be effective in preventing and treating problem gambling.

The multiple-family group intervention is an effective, yet affordable, 8-week treatment that is conducted in a juvenile correctional institution in Alabama with adolescents who sexually offend and their families. Data from 115 incarcerated male adolescents and their male and female caregivers collected at pre-, post-, and 1-year follow-up were used to determine that problem behaviors (internalizing, externalizing) decreased over pre- and posttest and the significant decreases in maladaptive emotion regulation predicted those changes. Adolescent-reported anxiety over abandonment and attachment dependence on parents increased significantly; these changes were predicted by decreases in maladaptive emotion regulation. Linear growth models were also fit over the 3 time points and indicate decreases in adolescent problem behavior and maladaptive emotion regulation.

Sensitizing young adults about sleep hygiene knowledge and helpful sleep attitudes may have the potential to instill long-lasting healthy sleep practices. Towards these ends, evaluation of psychoeducational program "Sleep 101" tailored to college students was undertaken. Following two weeks of sleep-log recordings, participants were randomly assigned to a Sleep 101 (experimental) condition or a sleep monitoring (control) condition. The Sleep 101 condition was comprised of two 90-minute workshops aimed to educate students about healthy sleep practices, helpful thoughts about sleep, and ways to improve sleep. The sleep monitoring group received a sleep hygiene handout and completed sleep logs for the study duration. Sleep 101 participants endorsed fewer maladaptive beliefs and attitudes about sleep, increased sleep hygiene knowledge, and reduced sleep onset latency compared to the sleep monitoring participants. Brief psychoeducational courses may be a cost-effective way to alleviate current, and/or prevent future, sleep problems in young adults.

Maladaptive arterial remodeling may constitute a mechanism underlying the risk of stroke in individuals with the metabolic syndrome (MetS), but evidence supporting this contention derives from cross-sectional studies only. We, therefore, investigated, in apparently healthy adults, whether changes in MetS status between the ages of 36 and 42 years (never [n=207, reference group], incident [n=31], recovery [n=23], and persistent [n=32]) were associated with changes in carotid interadventitial diameter, lumen diameter, intima-media thickness, circumferential wall tension and stress, and Young's elastic modulus. All data analyses were adjusted for sex, height, and (changes in) age, lifestyle variables, low-density lipoprotein cholesterol, and use of antihypertensive medication. At baseline and as compared with the reference group, individuals with persistent MetS had significantly higher interadventitial diameter, circumferential wall tension, circumferential wall stress, and Young's elastic modulus but not intima-media thickness. In the course of follow-up, these individuals (versus reference group) displayed significantly steeper increases in intima-media thickness (0.011 versus 0.005 mm/y), which were accompanied by significantly steeper increases in interadventitial diameter (0.077 versus 0.032 mm/y) and lumen diameter (0.055 versus 0.023 mm/y) but not circumferential wall stress, which decreased (-0.34 versus 0.12 kPa/y). These findings suggest that increases in intima-media thickness in young adults with the MetS may primarily reflect an adaptive mechanism that attempts to restore local hemodynamic conditions to an equilibrium rather than atherosclerosis, per se. However, carotid adaptations did not restore circumferential wall stress to levels comparable with those of the reference group, and, therefore, outward remodeling was maladaptive. Importantly, individuals who recovered from the MetS restored carotid properties to levels comparable to the reference group

Objective Social psychological theories provide bases for understanding how social comparison processes may impact peer influence. This study examined two peer characteristics that may impact peer influence on adolescent girls’ weight-related behavior intentions: body size and popularity. Method A school-based sample of 66 9th grade girls (12–15 years old) completed an experimental paradigm in which they believed they were interacting with other students (i.e., “e-confederates”). The body size and popularity of the e-confederates were experimentally manipulated. Participants were randomly assigned to one of the three experimental conditions in which they were exposed to identical maladaptive weight-related behavior norms communicated by ostensible female peers who were either: (1) Thin and Popular; (2) Thin and Average Popularity; or (3) Heavy and Average Popularity. Participants’ intent to engage in weight-related behaviors was measured pre-experiment and during public and private segments of the experiment. Results A significant effect of condition on public conformity was observed. Participants exposed to peers’ maladaptive weight-related behavior norms in the Heavy and Average condition reported significantly less intent to engage in weight-related behaviors than participants in either of the thin-peer conditions (F(2) = 3.93, p = .025). Peer influence on private acceptance of weight-related behavior intentions was similar across conditions (F(2) = .47, p = .63). Discussion Body size comparison may be the most salient component of peer influence processes on weight-related behaviors. Peer influence on weight-related behavior intention also appears to impact private beliefs. Considering peer norms in preventive interventions combined with dissonance-based approaches may be useful.

The prevalence of postural orthostatic tachycardia syndrome (POTS) in adolescents and young adults has been increasing during the past decade. Despite this increase, documentation regarding treatment of these patients is just beginning to emerge. In addition, despite a call for a multidisciplinary or interdisciplinary approach, no studies have examined the efficacy of such an approach to treatment. This paper describes a case study of a 19-year-old male with debilitating POTS seen at a tertiary clinic for evaluation and subsequent intensive interdisciplinary treatment. The treatment approach is described and outcomes are presented.
Genetic and Environmental Influences on Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) Maladaptive Personality Traits and Their Connections With Normative Personality Traits.
Wright, Zara E; Pahlen, Shandell; Krueger, Robert F
The Diagnostic and Statistical Manual for Mental Disorders-Fifth Edition (DSM-5) proposes an alternative model for personality disorders, which includes maladaptive-level personality traits. These traits can be operationalized by the Personality Inventory for the DSM-5 (PID-5). Although there has been extensive research on genetic and environmental influences on normative level personality, the heritability of the DSM-5 traits remains understudied. The present study addresses this gap in the literature by assessing traits indexed by the PID-5 and the International Personality Item Pool NEO (IPIP-NEO) in adult twins (N = 1,812 individuals). Research aims include (a) replicating past findings of the heritability of normative level personality as measured by the IPIP-NEO as a benchmark for studying maladaptive level traits, (b) ascertaining univariate heritability estimates of maladaptive level traits as measured by the PID-5, (c) establishing how much variation in personality pathology can be attributed to the same genetic components affecting variation in normative level personality, and (d) determining residual variance in personality pathology domains after variance attributable to genetic and environmental components of general personality has been removed. Results revealed that PID-5 traits reflect similar levels of heritability to that of IPIP-NEO traits. Further, maladaptive and normative level traits that correlate at the phenotypic level also correlate at the genotypic level, indicating overlapping genetic components contribute to variance in both. Nevertheless, we also found evidence for genetic and environmental components unique to maladaptive level personality traits, not shared with normative level traits. (PsycINFO Database Record

Research on adjustment of internationally adopted children indicates that, although they have adequate development, more emotional and behavioral problems are detected compared with nonadopted children. In this research, emotional and behavioral characteristics of a sample of 52 internationally adopted minors were examined with the BASC (Parent Rating Scales and Self-Report of Personality), comparing the outcomes with 44 nonadopted minors, all of them of ages between 6 and 11 years (mean age = 8.01 years). Results indicate differences between adopted and nonadopted children related to somatization, adopted minors are those that obtain lower scores in the scale, and in the adaptability scale, where nonadopted minors obtain higher scores. Significant differences were found in the adaptive abilities scales, suggesting that nonadopted boys show better abilities than adopted ones, and no differences were found among girls. In general, boys present higher scores in externalizing symptomatology and depression than girls. Among adopted children, time spent in an institution is a variable that has negative impact on the onset of externalizing and internalizing problems. Minors coming from Eastern Europe display more attentional problems, poorer adaptive abilities and poorer interpersonal relations than the rest of the minors. According to the age at placement, attentional problems appear in minors adopted after the age of 3 years.

Recent EEG and fMRI evidence suggests that behavioral errors are foreshadowed by systematic changes in brain activity preceding the outcome by seconds. In order to further characterize this type of error precursor activity, we investigated single-trial event-related EEG activity from 70 participants performing a modified Eriksen flanker task, in particular focusing on the trial-by-trial dynamics of a fronto-central independent component that previously has been associated with error and feedback processing. The stimulus-locked peaks in the N2 and P3 latency range in the event-related averages showed expected compatibility and error-related modulations. In addition, a small pre-stimulus negative slow wave was present at erroneous trials. Significant error-preceding activity was found in local stimulus sequences with decreased conflict in the form of less negativity at the N2 latency (310–350 ms) accumulating across five trials before errors; concomitantly response times were speeding across trials. These results illustrate that error-preceding activity in event-related EEG is associated with the performance monitoring system and we conclude that the dynamics of performance monitoring contribute to the generation of error-prone states in addition to the more remote and indirect effects in ongoing activity such as posterior alpha power in EEG and default mode drifts in fMRI.

Pre-operative treatment with recombinant human erythropoietin may improve aortic stenosis patients' condition, including anemia and/or cardiac dysfunction, for subjecting to aortic valve replacement. In this study, we tested this hypothesis in a mouse model of aortic stenosis. Adult male mice were subjected to either aortic stenosis created by aortic ligature or sham operation. Aortic stenosis for 4 weeks caused cardiac hypertrophy, pulmonary congestion and left ventricular dysfunction. It was associated with increased levels of tumor necrosis factor-alpha in serum and myocardium, and reduced levels of interleukin-10 in myocardium but not in serum. Myocyte apoptosis rate, level of cleaved caspase 3, activity of nuclear factor-kappaB and expression of p38-MAPK pathway were also elevated. Erythropoietin treatment increased hematocrit but did not prevent the development of cardiac hypertrophy. It, however, reduced the apoptosis, prevented the increases in tumor necrosis factor-alpha, nuclear factor-kappaB activation and phosphorylation of p38, and attenuated the increases in lung weight, the decreases in LVEF and LVFS, and the increases in LVDd and LVDs. In conclusion recombinant human erythropoietin has cardioprotective effects in maladaptive cardiac hypertrophy by inhibiting nuclear factor-kappaB activation, phosphorylation of p38-MAPK pathway, and production of tumor necrosis factor-alpha, together leading to a reduced apoptosis.

Although the current diagnostic manual conceptualizes personality disorders (PDs) as categorical entities, an alternative perspective is that PDs represent maladaptive extreme versions of the same traits that describe normal personality. Existing evidence indicates that normal personality traits, such as those assessed by the five-factor model (FFM), share a common structure and obtain reasonably predictable correlations with the PDs. However, very little research has investigated whether PDs are more extreme than normal personality traits. Utilizing item-response theory analyses, the authors of the current study extend previous research to demonstrate that the diagnostic criterion for borderline personality disorder and FFM neuroticism could be fit along a single latent dimension. Furthermore, the authors' findings indicate that the borderline criteria assessed the shared latent trait at a level that was more extreme (d = 1.11) than FFM neuroticism. This finding provides further evidence for dimensional understanding of personality pathology and suggests that a trait model in DSM-5 should span normal and abnormal personality functioning, but focus on the extremes of these common traits.

Synaptic plasticity is the process by which long-lasting changes take place at synaptic connections. The phenomenon itself is complex and can involve many levels of organization. Some authors separate forms into adaptations that have positive or negative consequences for the individual. It has been hypothesized that an increase in the number of synapses may represent a structural basis for the enduring expression of synaptic plasticity during some events that involve memory and learning; also, it has been suggested that perforated synapses increase in number after some diseases and experimental situations. The aim of this study was to analyze whether dopamine depletion induces changes in the synaptology of the corpus striatum of rats after the unilateral injection of 6-OHDA. The findings suggest that after the lesion, both contralateral and ipsilateral striata exhibit an increased length of the synaptic ending in ipsilateral (since third day) and contralateral striatum (since Day 20), loss of axospinous synapses in ipsilateral striatum and a significant increment in the number of perforated synapses, suggesting brain plasticity that might be deleterious for the spines, because this type of synaptic contacts are presumably excitatory, and in the absence of the modulatory effects of dopamine, the neuron could die through excitotoxic mechanisms. Thus, we can conclude that the presence of perforated synapses after striatal dopamine depletion might be a form of maladaptive synaptic plasticity.

The purpose of the current study was to examine the joint influences of experiential avoidance and social problem solving on the link between childhood emotional abuse (CEA) and intimate partner violence (IPV). Experiential avoidance following CEA may interfere with a person’s ability to effectively problem solve in social situations, increasing risk for conflict and interpersonal violence. As part of a larger study, 232 women recruited from the community completed measures assessing childhood emotional, physical, and sexual abuse, experiential avoidance, maladaptive social problem solving, and IPV perpetration and victimization. Final trimmed models indicated that CEA was indirectly associated with IPV victimization and perpetration via experiential avoidance and Negative Problem Orientation (NPO) and Impulsivity/Carelessness Style (ICS) social problem solving strategies. Though CEA was related to an Avoidance Style (AS) social problem solving strategy, this strategy was not significantly associated with IPV victimization or perpetration. Experiential avoidance had both a direct and indirect effect, via NPO and ICS social problem solving, on IPV victimization and perpetration. Findings suggest that CEA may lead some women to avoid unwanted internal experiences, which may adversely impact their ability to effectively problem solve in social situations and increase IPV risk.

Coping plays a central role in the appearance and persistence of pathological gambling. Anxious and depressive symptomatology also influence pathological gambling and are related to coping. This study aimed to analyze pathological gamblers' coping strategies and styles, as well as associated anxious and depressive symptomatology. The study sample included 167 male pathological gamblers (mean age = 39.29 years) and 107 non-gamblers (mean age = 33.43 years). Measures of gambling, coping, and anxious and depressive symptomatology were used. Results showed that pathological gamblers' scored higher in all the maladaptive coping strategies, problem- and emotion-focused disengagement, and disengagement subscales. These subscales also correlated with pathological gambling, and anxious and depressive symptomatology. Pathological gamblers also scored higher in emotional expression and emotion-focused engagement, with no differences in the rest of the adaptive coping strategies. Coping was also found to predict pathological gambling and anxious and depressive symptomatology. It was found that coping mediated the relationship between pathological gambling and anxious symptomatology when controlling for the effect of age. Specifically, social withdrawal and disengagement stood out as mediators. These results provide practical information for use in clinical settings with people diagnosed with pathological gambling.

Reintroductions are increasingly used to enhance declining populations, yet comparative data for critical germination and establishment phases are seldom available for both rare and common herbaceous perennials. After introducing a total of >1800 seeds, we compared experimentally manipulated and natural populations of widespread Silene douglasii var. douglasii relative to rare S. douglasii var. oraria, known in only three coastal headlands. Despite equivalent ex situ germination, oraria field plots produced significantly fewer juveniles than douglasii plots indicating that seedling survival limits plant establishment. We also evaluated transplant vs. seed reintroductions as restoration tools, the effect of inbreeding on fitness, and the potential importance of buried seed pools. Germination declined rapidly for seeds over 1-2 years old, and only 2.2% of newly collected seeds of oraria survived as seedlings. Transplant survival over 5 years was greatest for outbred progeny; furthermore, 75% of the new seedlings emerged near outbred progeny from the original reintroduction. Despite similar ovule numbers and pollinator visitation, transplants exhibited 49-179% maladaptation in the formerly grazed site, with significantly lower fruit and seed set than adults in more diverse natural populations. This study experimentally identifies several key factors affecting plant reintroductions, facilitating effective development of large-scale reintroduction strategies for native perennials.

Objective The purpose of this study is to assess the potential unique and relative mediating effects of three interpersonal risk factors (i.e., excessive reassurance-seeking [ERS], negative feedback seeking [NFS], and rejection sensitivity [RS]) in the relationship between childhood emotional abuse (CEA) and depressive symptoms. Method One hundred eighty-five undergraduates were followed over a four-month interval. Participants completed assessments of childhood abuse history, ERS, NFS, and RS, and depressive symptoms at baseline, as well as depressive symptoms at four-month followup. Results Findings from single-mediator analyses indicated that RS and NFS, but not ERS, mediated the relationship between CEA and prospective depressive symptoms, after accounting for childhood sexual and physical abuse, as well as baseline depressive symptoms. In our multi-mediator model, only RS remained a significant mediator of the relationship between CEA and prospective depressive symptoms. Conclusions The current study provides preliminary evidence that negative behavioral styles may function as a mechanism linking prior experiences of CEA to subsequent depressive symptoms. Clinical implications of these findings suggest that targeting maladaptive behavioral tendencies, particularly RS, may be an effective adjunct in behavioral modification treatments of CEA victims at risk for depression.

The relationships between two measures proposed to describe personality pathology, that is the Revised NEO Personality Inventory (NEO-PI-3) and the Personality Inventory for DSM-5 (PID-5), are examined in an undergraduate sample (N = 240). The NEO inventories are general trait measures, also considered relevant to assess disordered personality, whereas the PID-5 measure is specifically designed to assess pathological personality traits, as conceptualized in the DSM-5 proposal. A structural analysis of the 25 PID-5 traits confirmed the factor structure observed in the U.S. derivation sample, with higher order factors of Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism. A joint factor analysis of, respectively, the NEO domains and their facets with the PID-5 traits showed that general and maladaptive traits are subsumed under an umbrella of five to six major dimensions that can be interpreted from the perspective of the five-factor model or the Personality Psychopathology Five. Implications for the assessment of personality pathology and the construction of models of psychopathology grounded in personality are discussed.

We investigated whether prior exposure to chronic wheel running (WR) alters maladaptive patterns of excessive and escalating methamphetamine intake under extended access conditions, and intravenous methamphetamine self-administration-induced neurotoxicity. Adult rats were given access to WR or no wheel (sedentary) in their home cage for 6 weeks. A set of WR rats were injected with 5-bromo-2'-deoxyuridine (BrdU) to determine WR-induced changes in proliferation (2-h old) and survival (28-day old) of hippocampal progenitors. Another set of WR rats were withdrawn (WRw) or continued (WRc) to have access to running wheels in their home cages during self-administration days. Following self-administration [6 h/day], rats were tested on the progressive ratio (PR) schedule. Following PR, BrdU was injected to determine levels of proliferating progenitors (2-h old). WRc rats self-administered significantly less methamphetamine than sedentary rats during acquisition and escalation sessions, and demonstrated reduced motivation for methamphetamine seeking. Methamphetamine reduced daily running activity of WRc rats compared with that of pre-methamphetamine days. WRw rats self-administered significantly more methamphetamine than sedentary rats during acquisition, an effect that was not observed during escalation and PR sessions. WR-induced beneficial effects on methamphetamine self-administration were not attributable to neuroplasticity effects in the hippocampus and medial prefrontal cortex, but were attributable to WR-induced inhibition of methamphetamine-induced increases in the number of neuronal nitric oxide synthase expressing neurons and apoptosis in the nucleus accumbens shell. Our results demonstrate that WR prevents methamphetamine-induced damage to forebrain neurons to provide a beneficial effect on drug-taking behavior. Importantly, WR-induced neuroprotective effects are transient and continued WR activity is necessary to prevent compulsive methamphetamine intake.

Spinal cord injury (SCI) causes chronic peripheral sensitization of nociceptors and persistent generation of spontaneous action potentials (SA) in peripheral branches and the somata of hyperexcitable nociceptors within dorsal root ganglia (DRG). Here it is proposed that SCI triggers in numerous nociceptors a persistent hyperfunctional state (peripheral, synaptic, and somal) that originally evolved as an adaptive response to compensate for loss of sensory terminals after severe but survivable peripheral injury. In this hypothesis, nociceptor somata monitor the status of their own receptive field and the rest of the body by integrating signals received by their peripheral and central branches and the soma itself. A nociceptor switches into a potentially permanent hyperfunctional state when central neural, glial, and inflammatory signal combinations are detected that indicate extensive peripheral injury. Similar signal combinations are produced by SCI and disseminated widely to uninjured as well as injured nociceptors. This paper focuses on the uninjured nociceptors that are altered by SCI. Enhanced activity generated in below-level nociceptors promotes below-level central sensitization, somatic and autonomic hyperreflexia, and visceral dysfunction. If sufficient ascending fibers survive, enhanced activity in below-level nociceptors contributes to below-level pain. Nociceptor activity generated above the injury level contributes to at- and above-level sensitization and pain (evoked and spontaneous). Thus, SCI triggers a potent nociceptor state that may have been adaptive (from an evolutionary perspective) after severe peripheral injury but is maladaptive after SCI. Evidence that hyperfunctional nociceptors make large contributions to behavioral hypersensitivity after SCI suggests that nociceptor-specific ion channels required for nociceptor SA and hypersensitivity offer promising targets for treating chronic pain and hyperreflexia after SCI.

Acute metabolic stress such as insulin-induced hypoglycemia triggers a counterregulatory response during which the release of catecholamines (epinephrine), the activation of tyrosine hydroxylase (TH) enzyme and subsequent compensatory catecholamine biosynthesis occur in the adrenal medulla. However, recurrent exposure to hypoglycemia (RH), a consequence of tight glycemic control in individuals with type 1 and type 2 diabetes compromises this physiological response. The molecular mechanisms underlying the maladaptive response to repeated glucose deprivation are incompletely understood. We hypothesize that impaired epinephrine release following RH reflects altered regulation of adrenal catecholamine biosynthesis. To test this hypothesis, we compared the effect of single daily (RH) and twice-daily episodes of insulin-induced hypoglycemia (2RH) on adrenal epinephrine release and production in normal rats. Control animals received saline injections under similar conditions (RS and 2RS, respectively). Following 3 days of treatment, we assessed the counterregulatory hormonal responses during a hypoglycemic clamp. Changes in adrenal TH gene expression were also analyzed. The counterregulatory responses, relative TH transcription and TH mRNA levels and Ser40-TH phosphorylation (marker for enzyme activation) were induced to a similar extent in RS, 2RS, and RH groups. In contrast, epinephrine and glucagon responses were attenuated in the 2RH group and this was associated with a limited elevation of adrenal TH mRNA, rapid inactivation of TH enzyme and no significant changes in TH protein. Our results suggest that novel posttranscriptional mechanisms controlling TH mRNA and activated TH enzyme turnover contribute to the impaired epinephrine responses and may provide new therapeutic targets to prevent HAAF.

The present paper aims to longitudinally assess the emotional functioning of children of mothers with depression, anxiety, or eating disorders and of mothers with no psychological disorders and to evaluate the possible mediating role of fathers' psychological profiles on children's internalizing/externalizing functioning using SCID I, SCL-90/R and CBCL/1½-5. The results showed maternal psychopathology to be strongly related to children's maladaptive profiles. Children of mothers with depression and anxiety showed higher internalizing scores than children of other groups. These scores increased from T1 to T2. Children of mothers with eating disorders showed higher and increasing externalizing scores than children of other groups. The data showed that fathers' interpersonal sensitivity, depression, anxiety and psychoticism significantly predicted internalizing problems of the children. Moreover, interpersonal sensitivity and psychoticism significantly predicted externalizing problems. Our results confirmed the impact of maternal psychopathology on maladaptive outcomes in their children, which suggests the importance of considering paternal psychological profiles.

Over the past two decades, evidence has suggested that personality disorders (PDs) can be conceptualized as extreme, maladaptive variants of general personality dimensions, rather than discrete categorical entities. Recognizing this literature, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) alternative PD model in Section III defines PDs partially through 25 maladaptive traits that fall within 5 domains. Empirical evidence based on the self-report measure of these traits, the Personality Inventory for DSM-5 (PID-5), suggests that these five higher-order domains share a structure and correlate in meaningful ways with the five-factor model (FFM) of general personality. In the current study, item response theory was used to compare the DSM-5 alternative PD model traits to those from a normative FFM inventory (the International Personality Item Pool-NEO [IPIP-NEO]) in terms of their measurement precision along the latent dimensions. Within a combined sample of 3,517 participants, results strongly supported the conclusion that the DSM-5 alternative PD model traits and IPIP-NEO traits are complimentary measures of 4 of the 5 FFM domains (with perhaps the exception of openness to experience vs. psychoticism). Importantly, the two measures yield largely overlapping information curves on these four domains. Differences that did emerge suggested that the PID-5 scales generally have higher thresholds and provide more information at the upper levels, whereas the IPIP-NEO generally had an advantage at the lower levels. These results support the general conceptualization that 4 domains of the DSM-5 alternative PD model traits are maladaptive, extreme versions of the FFM. (PsycINFO Database Record

This study explored the association between personal resilience and distress, coping, and diabetes outcomes in 50 adolescents with type 1 diabetes. Resilience was defined by a factor score derived from validated instruments measuring self-efficacy, optimism, and self-esteem. Variable- and person-focused methodologies were used to explore these associations. Low resilience was associated with higher distress, poor quality of life, and poor glycemic control. Participants with low resilience used more maladaptive coping strategies and were at greatest risk of poor outcomes. Findings suggest that resilience is a promising candidate for interventions designed to reduce distress and improve outcomes for adolescents with type 1 diabetes.

The aim of this study was to examine the psychometric properties and preliminary validity of a newly developed 16-item measure to assess maladaptive responses to the stress of being at risk for HIV infection among HIV-negative gay men. The measure consisted of three factors: (1) fatalistic beliefs about maintaining an HIV-negative serostatus; (2) reduced perceived severity of HIV infection due to advances in medical treatment of HIV/AIDS; and (3) negative affective states associated with the risk of HIV infection. A total of 285 HIV-negative gay men at a counseling program in New York City participated in the study. Confirmatory factor analyses supported the three-factor model as an acceptable model fit: NNFI = .91, CFI = .92, GFI = .90, RMSEA = .07. The measure and its subscales obtained in this sample achieved adequate internal consistency coefficients. Construct validity was supported by significant positive associations with internalized homophobia, depression, self-justifications for the last unprotected anal intercourse (UAI), and actual UAI with casual sex partners. Understanding the dynamics of maladaptive responses to the epidemic and intense anxieties elicited by HIV risk among HIV-negative gay men living in a place of high seroprevalence provides useful information to guide psychosocial interventions in the population.

Maladaptive plasticity can be defined as behavioral loss or even development of disease symptoms resulting from aberrant plasticity changes in the human brain. Hyperkinetic movement disorders, in the neurological or psychiatric realms, have been associated with maladaptive neural plasticity that can be expressed by functional changes such as an increase in transmitter release, receptor regulation, and synaptic plasticity or anatomical modifications such as axonal regeneration, sprouting, synaptogenesis, and neurogenesis. Recent evidence from human and animal models provided support to the hypothesis that these phenomena likely depend on altered dopamine turnover induced by long-term drug treatment. However, it is still unclear how and where these altered mechanisms of cortical plasticity may be localized. This study provides an up-to-date overview of these issues together with some reflections on future studies in the field, particularly focusing on two specific disorders (levodopa-induced dyskinesias in Parkinson's disease patients and tardive dyskinesias in schizophrenic patients) where the modern neuroimaging approaches have recently provided new fundamental insights.

This study examined differences in friendship quality between children with traumatic brain injury (TBI) and orthopedic injury (OI) and behavioral outcomes for children from both groups. Participants were 41 children with TBI and 43 children with OI (M age = 10.4). Data were collected using peer- and teacher-reported measures of participants’ social adjustment and parent-reported measures of children’s post-injury behaviors. Participants and their mutually nominated best friends also completed a measure of the quality of their friendships. Children with TBI reported significantly more support and satisfaction in their friendships than children with OI. Children with TBI and their mutual best friend were more similar in their reports of friendship quality compared to children with OI and their mutual best friends. Additionally, for children with TBI who were rejected by peers, friendship support buffered against maladaptive psychosocial outcomes, and predicted skills related to social competence. Friendship satisfaction was related to higher teacher ratings of social skills for the TBI group only. Positive and supportive friendships play an important role for children with TBI, especially for those not accepted by peers. Such friendships may protect children with TBI who are rejected against maladaptive psychosocial outcomes, and promote skills related to social competence. PMID:24840021

Blood motion in the heart features vortices that accompany the redirection of jet flows towards the outlet tracks. Vortices have a crucial role in fluid dynamics. The stability of cardiac vorticity is vital to the dynamic balance between rotating blood and myocardial tissue and to the development of cardiac dysfunction. Moreover, vortex dynamics immediately reflect physiological changes to the surrounding system, and can provide early indications of long-term outcome. However, the pathophysiological relevance of cardiac fluid dynamics is still unknown. We postulate that maladaptive intracardiac vortex dynamics might modulate the progressive remodelling of the left ventricle towards heart failure. The evaluation of blood flow presents a new paradigm in cardiac function analysis, with the potential for sensitive risk identification of cardiac abnormalities. Description of cardiac flow patterns after surgery or device therapy provides an intrinsic qualitative evaluation of therapeutic procedures, and could enable early risk stratification of patients vulnerable to adverse cardiac remodelling.
Whilst cognitive-behavioural therapy has demonstrated efficacy in the treatment of eating disorders, therapy outcomes and current conceptualizations still remain inadequate. In light of these shortcomings there has been growing interest in the utility of schema therapy applied to eating pathology. The present article first provides a narrative review of empirical literature exploring schemas and schema processes in eating disorders. Secondly, it critically evaluates outcome studies assessing schema therapy applied to eating disorders. Current evidence lends support to schema-focused conceptualizations of eating pathology and confirms that eating disorders are characterised by pronounced maladaptive schemas. Treatment outcomes also indicate that schema therapy, the schema-mode approach, and associated techniques are promising interventions for complex eating disorders. Implications for clinical practice and future directions for research are discussed.

Existing literature examining the relation between social networking sites and mental health is primarily based on correlational methods and presents mixed findings. Many researchers neglect to examine the cognitive and behavioral processes used while online. This study’s qualitative approach strives to understand how individuals with elevated depressive symptoms may use Facebook following an interpersonal stressor. Participants’ narration of their Facebook use was coded. Common adaptive uses included using Facebook to seek social support, actively communicate, distract, recall positive memories, and reappraise negative thoughts. Maladaptive uses included engaging in social comparison, ruminating, and recalling negative memories. Feedback regarding development of a future intervention was also elicited. Suggestions included using Facebook to view positive, interesting, or meaningful information, distract, garner social support, and engage in social activities. Findings indicate that how one engages with Facebook after an interpersonal stressor may affect adjustment and may help to inform the development of a novel, Facebook-based intervention.

The Developmental Audit[R] is a comprehensive means of assessment and treatment planning that identifies the coping strategies underlying a youth's maladaptive and self-defeating behavior. This is a strength-based assessment that engages youth in conflict in the process of generating solutions rather than focusing on deficits. This process…

Stein, Riedel, and Rotheram-Borus reported in 1999 that early parentification predicted maladaptive outcomes of more emotional distress, substance use, and conduct problems among adolescents of parents with HIV/AIDS (PWH) 6 months later. The current study assessed the adolescents (N = 213) 6 years later to assess whether there were continuing negative effects of parentification, or, rather, if there were some positive outcomes. Although the premature assumption of parental roles had negative effects in the short term, we hypothesized that such skills may have been adaptive in the long run, especially in the case of adolescents with major stressors in their lives, including dying or ill parents, impoverished environments, and family instability. We found that early parentification predicted better adaptive coping skills and less alcohol and tobacco use 6 years later. In addition, early parentification was not associated with later emotional distress and dysfunctional parenting attitudes, including expecting role reversals in their own children.
The schema therapy model posits that maltreatment generates early maladaptive schemas (EMSs) that lead to the development of emotional disorders throughout the life span. The model also stipulates that temperament moderates the influence of maltreatment on EMSs. This study examines (a) whether emotional abuse perpetrated by parents and peers, both alone and interactively with temperament, predicts the worsening of EMSs; and (b) whether EMSs in turn predict an increase in depressive and social anxiety symptoms in adolescents. A total of 1,052 adolescents (Mage=13.43; SD=1.29) were assessed at three time points, each of which was separated by 6 months. The subjects completed measures of emotional abuse by parents and peers, neuroticism, extraversion, EMSs, depressive symptoms, and social anxiety. The findings indicate that emotional bullying victimization and neuroticism predict a worsening of all schema domains over time. Contrary to expectations, there was no significant interaction between temperament dimensions and emotional abuse. The results confirmed the mediational hypothesis that changes in EMSs mediated the predictive association between bullying victimization and emotional symptoms. This study provides partial support for the schema therapy model by demonstrating the role of emotional abuse and temperament in the genesis of EMSs.

Parental effects passed from adults to their offspring have been identified as a source of rapid acclimation that may allow marine populations to persist as our surface oceans continue to decrease in pH. Little is known, however, whether parental effects are beneficial for offspring in the presence of multiple stressors. We exposed adults of the oyster Saccostrea glomerata to elevated CO2 and examined the impacts of elevated CO2 (control = 392; 856 µatm) combined with elevated temperature (control = 24; 28°C), reduced salinity (control = 35; 25) and reduced food concentration (control = full; half diet) on their larvae. Adult exposure to elevated CO2 had a positive impact on larvae reared at elevated CO2 as a sole stressor, which were 8% larger and developed faster at elevated CO2 compared with larvae from adults exposed to ambient CO2 These larvae, however, had significantly reduced survival in all multistressor treatments. This was particularly evident for larvae reared at elevated CO2 combined with elevated temperature or reduced food concentration, with no larvae surviving in some treatment combinations. Larvae from CO2-exposed adults had a higher standard metabolic rate. Our results provide evidence that parental exposure to ocean acidification may be maladaptive when larvae experience multiple stressors.

The Diagnostic and Statistical Manual of Mental Disorders-Fifth edition (DSM-5) Personality and Personality Disorders workgroup developed the Personality Inventory for the DSM-5 (PID-5) for the assessment of the alternative trait model for DSM-5 Along with this measure, the American Psychiatric Association published an abbreviated version, the PID-5-Brief form (PID-5-BF). Although this measure is available on the DSM-5 website for use, only two studies have evaluated its psychometric properties and validity and no studies have examined the U.S. version of this measure. The current study evaluated the reliability, factor structure, and construct validity of PID-5-BF scale scores. This included an evaluation of the scales' associations with Section II PDs, a well-validated dimensional measure of personality psychopathology, and broad externalizing and internalizing psychopathology measures. We found support for the reliability of PID-5-BF scales as well as for the factor structure of the measure. Furthermore, a series of correlation and regression analyses showed conceptually expected associations between PID-5-BF and external criterion variables. Finally, we compared the correlations with external criterion measures to those of the full-length PID-5 and PID-5-Short form. Intraclass correlation analyses revealed a comparable pattern of correlations across all three measures, thereby supporting the use of the PID-5-BF as a screening measure of dimensional maladaptive personality traits.

The Personality Inventory for DSM-5 (PID-5), a new measure of maladaptive personality traits, has recently been developed by the DSM-5 Personality and Personality Disorders Workgroup. The PID-5 variables were examined within the seven-factor space defined by the six HEXACO factors and the Schizotypy/Dissociation factor (Ashton & Lee, 2012) using participant samples from Canada (N = 378) and the Netherlands (N = 476). Extension analyses showed that several PID-5 facet-level scales represented each of the Honesty-Humility, Emotionality, Extraversion, Conscientiousness, and Schizotypy/Dissociation factors. In contrast, only one PID-5 scale loaded strongly on HEXACO Agreeableness, and no PID-5 scales loaded strongly on Openness to Experience. In addition, a joint factor analysis involving the PID-5 variables and facets of the Five-Factor Model was conducted in the Canadian sample and recovered a set of seven factors corresponding rather closely to the HEXACO factors plus Schizotypy/Dissociation. The authors discuss implications for the assessment and structure of normal and abnormal personality.

A number of studies have reported an association between 5-HTTLPR, a polymorphism of the serotonin transporter gene, and the development of depressive states in response to a variety of distal and proximal stressors. We report here studies of the effects of the 5-HTTLPR polymorphism on the probability that an individual will develop mental maladaptation in 224 close relatives of patients with severe chronic mental disorders - schizophrenia and schizoaffective and affective psychoses. The ss genotype of the serotonin transporter gene contributes to the formation predominantly of manifestations of distress, reflected by increases on the hypochondriasis scale of the MMPI scale of factors such as the extent of the autonomic component of anxiety reactions and increased attention to own health, as well as increases in sensitivity. At the same time, the ss genotype was less likely to influence the appearance of depression and anxiety, as determined on the depression scale. These tendencies were more marked in males than females. Furthermore, males with the ss genotype were characterized by some increase in tension, suspicion, detachment, and attention difficulty (on the paranoia and schizophrenia scales). These data can be regarded as supporting the role of the short allele of the serotonin transporter gene in enhancing and modulating psychopathological reactions to chronic stress situations in relatives of mental patients.

Acute and chronic critical conditions are associated with reduced serum levels of free triiodothyronine (FT(3)), free thyroxine FT(4), and thyrotropin, known as nonthyroidal illness syndrome (NTIS). It is still controversial whether these changes reflect a protective mechanism or a maladaptive process during prolonged illness. However, larger studies to determine the prevalence of the NTIS and its association with outcome in medical intensive care units (ICUs) are missing. Complete thyroid hormone levels from 247 of 743 patients admitted to our ICU between October 2002 and February 2004 were retrospectively evaluated. From these patients, Acute Physiology and Chronic Health II scores, ICU mortality, length of stay, mechanical ventilation, and concomitant medication were recorded. Ninety-seven patients (44.1%) had low FT(3) levels indicating an NTIS, either with normal (23.6%) or reduced (20.5%) serum thyrotropin levels. Of 97 patients with NTIS, 24 (23.3%) also showed reduced serum FT(4) levels. The NTIS was significantly associated with Acute Physiology and Chronic Health II scores, mortality, length of stay, and mechanical ventilation. In a multivariate Cox regression analysis, the combination of low FT(3) and low FT(4) was an independent risk factor for survival. Nonthyroidal illness syndrome is frequent at a medical ICU. A reduction of FT(4) together with FT(3) is associated with an increase in mortality and might reflect a maladaptive process, thereby worsening the disease.

Maternal immunity undergoes subtle adjustment in order to tolerate the semi-allogeneic embryo and maintain the host defense against potential pathogens. Concomitantly, coagulation systems change from an anti-coagulant state to a pro-coagulant state to meet the hemostatic challenge of placentation and delivery. Innate immunity and blood coagulation systems are the first line of defense to protect a host against exogenous challenges, including alloantigens and mechanical insults, and preserve the integrity of an organism. The interactions between coagulation and immune systems have been extensively studied. Immune cells play a pivotal role in the initiation of the coagulation cascade, whereas coagulation proteases display substantial immuno-modulatory effects. Upon exogenous challenges, the immune and coagulation systems are capable of potentiating each other leading to a vicious cycle. Natural killer (NK) cells, macrophages (Mphis) and dendritic cells (DCs) are three major innate immune cells that have been demonstrated to play essential roles in early pregnancy. However, immune maladaptation and hemostatic imbalance have been suggested to be responsible for adverse pregnant outcomes, such as preeclampsia (PE), miscarriage, recurrent spontaneous abortion (RSA) and intrauterine growth restriction (IUGR). In this review, we will summarize the mutual regulation between blood coagulation and innate immune systems as well as their roles in the maintenance of normal pregnancy and in the pathogenesis of adverse pregnancy outcomes.

There is growing interest in whether the parenting strategies and offspring outcomes of mothers with borderline personality disorder (BPD) differ from those of mothers without BPD. We searched PsychINFO, PubMed, EMBASE, Web of Science, Scopus and ASSIA databases for studies examining parenting skills and attitudes among mothers with BPD/BPD symptoms and/or offspring outcomes. PRISMA reporting guidelines were followed. Of 10,067 abstracts screened, 101 full-text articles were retrieved and 33 met pre-determined criteria for qualitative synthesis. Overall, studies suggest that mothers with BPD/BPD symptoms are more likely to engage in maladaptive interactions with their offspring characterised by insensitive, overprotective, and hostile parenting compared to mothers without BPD/BPD symptoms. Adverse offspring outcomes include BPD symptoms, internalising (including depression) and externalising problems, insecure attachment patterns, and emotional dysregulation. Findings suggest that vulnerability from mother to offspring may be partly transmitted via maladaptive parenting and maternal emotional dysfunction. Conclusions were limited by study heterogeneity in methodology and construct definitions, as well as a paucity of clinical comparison groups. Prospective studies of mothers with BPD and their offspring from pregnancy onwards may further elucidate mechanisms of transmission and identify resilience factors across development. Parenting behaviour awareness, improving attachment behaviours and emotional regulation strategies may be important intervention targets.

Outcomes research uses diverse inputs to examine innovative end results aimed to deliver quality patient care. Yet defining "outcomes research" remains a challenge, and its interpretation is often nuanced. In this review, we discuss the definition of outcomes research in the context of its historical evolution along with the rise of other similar types of research. We then discuss key considerations in interpreting the results of outcomes analysis.

Much of contemporary associative learning research is focused on understanding how and when the associative history of cues affects later learning about those cues. Very little work has investigated the effects of the associative history of outcomes on human learning. Three experiments extended the "learned irrelevance" paradigm from the animal conditioning literature to examine the influence of an outcome's prior predictability on subsequent learning of relationships between cues and that outcome. All 3 experiments found evidence for the idea that learning is biased by the prior predictability of the outcome. Previously predictable outcomes were readily associated with novel predictive cues, whereas previously unpredictable outcomes were more readily associated with novel nonpredictive cues. This finding highlights the importance of considering the associative history of outcomes, as well as cues, when interpreting multistage designs. Associative and cognitive explanations of this certainty matching effect are discussed.

Sensory features are prevalent and heterogeneous across children with ASD and these features have been associated with child outcomes. Identification of clinically defined sensory subtypes may enhance our understanding of unique phenotypes that have implications for etiology, prognosis, and intervention. This longitudinal study used a national online survey aimed to identify associations of previously validated sensory subtypes to specific child and family characteristics and functional outcomes [vineland adaptive behavior scale-II (VABS) and parenting stress index short form (PSI)]. The sensory experiences questionnaire-3.0 was collected from caregivers with children with ASD, ages 2-12, at two time points (Time 1, n = 1307, Time 2, n = 884), 1 year apart. Functional outcomes assessments were collected at the second time point. A latent profile transition analysis (LPTA) was used to test associations, and results indicated that the attenuated-preoccupied subtype presented with the significantly lowest levels of VABS adaptive behavior composite scores compared to the other three sensory subtypes. Both the VABS maladaptive behavior index and the total PSI score were significantly highest in the extreme-mixed subtype. These results underscore the clinical utility of this subtyping approach for differentiating characteristics and functional outcomes associated with clinically defined sensory phenotypes. These findings may have implications for better understanding etiology, prognosis, and more precise targets for interventions designed to ameliorate sensory difficulties, and ultimately mitigate negative developmental consequences and parenting stress.

In non-meditating samples, distinct facets of mindfulness are found to be negatively correlated, preventing the meaningful creation of a total mindfulness score. The present study used person-centered analyses to distinguish subgroups of college students based on their mindfulness scores, which allows the examination of individuals who are high (or low) on all facets of mindfulness. Using the Lo-Mendell-Rubin Adjusted LRT test, we settled on a 4-class solution that included a high mindfulness group (high on all 5 facets, N = 245), low mindfulness group (moderately low on all 5 facets, N = 563), judgmentally observing group (high on observing, but low on non-judging and acting with awareness, N =63), and non-judgmentally aware group (low on observing, but high on non-judging and acting with awareness, N =70). Consistent across all emotional outcomes including depressive symptoms, anxiety symptoms (i.e., worry), affective instability, and distress intolerance, we found that the judgmentally observing group had the most maladaptive emotional outcomes followed by the low mindfulness group. Both the high mindfulness group and the non-judgmentally aware group had the most adaptive emotional outcomes. We discuss the implications of person-centered analyses to exploring mindfulness as it relates to important psychological health outcomes.

Disorganized/controlling attachment in preschool has been found to be associated with maternal and child maladjustment, making it of keen interest in the study of psychopathology. Additional work is needed, however, to better understand disorganized/controlling attachment occurring as early as age three. The primary aims of this study were to evaluate risk factors and outcomes associated with disorganized/controlling behavior at age three and to evaluate the risk factors and outcomes differentiating the four subtypes of disorganized/controlling attachment. Analyses were conducted with the first two phases of the NICHD Study of Early Child Care and Youth Development, a prospective study of 1,364 children from birth. At 36 months of age, across the attachment-relevant domains of maternal well-being, mother-child interactions, and child social adaptation, the disorganized/controlling group evidenced the most maladaptive patterns in comparison to both secure and insecure-organized groups. At 54 months of age, the disorganized/controlling group displayed the highest levels of internalizing and externalizing behavior problems, as rated by mothers and teachers, and the lowest quality relationships with teachers. Significant differences found among the disorganized/controlling subtypes indicated that the behaviorally disorganized and controlling-punitive subtypes had more maladaptive patterns across variables than did the controlling-caregiving and controlling-mixed subtypes.

An experimental model of early-stage cardiomyopathy was created by immunizing rabbits for 1 year with synthetic peptides corresponding to the sequence of the second extracellular loop of either beta-adrenoceptors or M2-muscarinic receptors. Thirty male rabbits were used and divided into three groups: a control group (n = 10), a group immunized with the peptide corresponding to the beta-adrenoceptor (beta 1 group) (n = 10) and a group immunized with the peptide corresponding to the M2-muscarinic receptor (M2 group) (n = 10). If the sera from both groups of immunized rabbits high-titres of anti-peptide antibodies were found throughout the study period but not in the sera from control rabbits or in the preimmune sera of immunized rabbits. No significant cross-reaction with peptides other than those used for immunization was found. The myocardial receptor density of both immunized groups displayed a strong trend toward receptor up-regulation. This was significant in the beta 1 group but not in the M2 group. Both groups of immunized rabbits displayed significantly enlarged ventricles and thinner walls, as compared with the control group. However, in contrast to the beta 1 group, which showed enlarged cavities in both left and right ventricles, the M2 group was mainly affected in the right ventricles. Moreover, morphological examinations of the hearts of rabbits from both immunized groups demonstrated focal myofibrillar lysis, loss of myofilament, mitochondrial swelling and condensation, sarcoplasmic vacuolation, deposition of dense granules in the sarcoplasm and the myofibrils. One of the sex control rabbit hearts which were examined showed mild degenerative changes in the myocardium and scant mononuclear cell infiltration. However, when all the control rabbit hearts were examined by electron microscopy, no significant alterations were found. These results suggest that immunization by peptides, corresponding to the target sequences for anti-receptor autoantibodies in idiopathic dilated cardiomyopathy, induces morphological changes in the heart similar to those found in the human disease.

The aim of the present study was to assess the effects of an anticholinesterase agent, pyridostigmine bromide (Pyrido), on experimental chronic Chagas heart disease in mice. To this end, male C57BL/6J mice noninfected (control:Con) or chronically infected (5 months) with Trypanosoma cruzi (chagasic:Chg) were treated or not (NT) with Pyrido for one month. At the end of this period, electrocardiogram (ECG); cardiac autonomic function; heart histopathology; serum cytokines; and the presence of blood and tissue parasites by means of immunohistochemistry and PCR were assessed. In NT-Chg mice, significant changes in the electrocardiographic, autonomic, and cardiac histopathological profiles were observed confirming a chronic inflammatory response. Treatment with Pyrido in Chagasic mice caused a significant reduction of myocardial inflammatory infiltration, fibrosis, and hypertrophy, which was accompanied by a decrease in serum levels of IFNγ with no change in IL-10 levels, suggesting a shift of immune response toward an anti-inflammatory profile. Lower nondifferent numbers of parasite DNA copies were observed in both treated and nontreated chagasic mice. In conclusion, our findings confirm the marked neuroimmunomodulatory role played by the parasympathetic autonomic nervous system in the evolution of the inflammatory-immune response to T. cruzi during experimental chronic Chagas heart disease in mice.

Background Outcomes of pulmonary physiology have a central place in asthma clinical research. Objective At the request of National Institutes of Health (NIH) institutes and other federal agencies, an expert group was convened to provide recommendations on the use of pulmonary function measures as asthma outcomes that should be assessed in a standardized fashion in future asthma clinical trials and studies to allow for cross-study comparisons. Methods Our subcommittee conducted a comprehensive search of PubMed to identify studies that focused on the validation of various airway response tests used in asthma clinical research. The subcommittee classified the instruments as core (to be required in future studies), supplemental (to be used according to study aims and in a standardized fashion), or emerging (requiring validation and standardization). This work was discussed at an NIH-organized workshop in March 2010 and finalized in September 2011. Results A list of pulmonary physiology outcomes that applies to both adults and children older than 6 years was created. These outcomes were then categorized into core, supplemental, and emerging. Spirometric outcomes (forced expiratory volume in 1 second [FEV1], forced vital capacity [FVC], and FEV1/FVC) are proposed as core outcomes for study population characterization, for observational studies, and for prospective clinical trials. Bronchodilator reversibility and pre- and post-bronchodilator FEV1 also are core outcomes for study population characterization and observational studies. Conclusions The subcommittee considers pulmonary physiology outcomes of central importance in asthma and proposes spirometric outcomes as core outcomes for all future NIH-initiated asthma clinical research.

The aim of this study was to determine the behavioral outcome in children with CAH and to identify the risk factors that may influence it. Participants (aged 6–18 years) included 29 girls and 20 boys with CAH and unaffected siblings (25 girls and 17 boys). Psychological adjustment was assessed with parent reports on the Child Behavior Checklist (CBCL). Information about disease characteristics was obtained from medical records. Our study reveals that there was higher incidence of parent-reported problem of anxious/depressed and withdrawn/depressed behaviours, somatic complaints, social, thought, and attention problems, and rule-breaking, aggressive, internalizing, and externalizing behaviour among children with CAH compared to controls. The prevalence of internalizing behaviour problems was higher in CAH boys compared with that of controls. Psychosocial adjustment of girls with CAH was found to be similar to unaffected female controls and was within the normal population range. Family income may be associated with behavioral outcome. Glucocorticoid dose may reflect disease severity which may be associated with behavioral outcome. We conclude that internalizing behavioral problem was prevalent among boys with CAH reflecting maladaptive adjustment in coping with chronic illness. This highlighted the importance of psychological and social support for the patients and their families. PMID:24799898

Maternal adverse childhood experiences (ACEs) have been associated with negative physical and mental health outcomes in adulthood. Less is known regarding how maternal ACEs relate to perinatal depressive symptoms or the intergenerational effect of maternal childhood trauma history on birth outcomes and infant functioning. To address this gap, an at-risk sample of 398 pregnant women was recruited from Women, Infants, and Children health clinics. Participants completed a prenatal (M = 4.84 months before due date) and postnatal (M = 6.76 months after birth) assessment and provided birth outcome data. At the prenatal assessment, mothers completed an ACEs measure which assessed experiences of childhood maltreatment and household dysfunction. Self-report measures of maternal depressive symptoms were obtained at both time points. Mothers reported on infant socioemotional functioning at 6 months. Maternal ACEs predicted higher levels of prenatal depressive symptoms. Childhood maltreatment experiences, in particular, predicted higher postnatal depressive symptoms and a smaller reduction in depressive symptoms across the perinatal period. Regarding intergenerational associations, maternal childhood maltreatment directly predicted higher levels of maladaptive infant socioemotional symptoms, whereas maternal household dysfunction indirectly related to infant socioemotional symptoms through maternal age at first pregnancy and infant birth weight. Limitations and future directions are discussed.

This study was designed to test the feasibility and child clinical outcomes for group-based trauma-focused cognitive behavior therapy (TF-CBT) for orphaned children in Tanzania. There were 64 children with at least mild symptoms of grief and/or traumatic stress and their guardians who participated in this open trial. The TF-CBT for Child Traumatic Grief protocol was adapted for use with a group, resulting in 12 weekly sessions for children and guardians separately with conjoint activities and 3 individual visits with child and guardian. Using a task-sharing approach, the intervention was delivered by lay counselors with no prior mental health experience. Primary child outcomes assessed were symptoms of grief and posttraumatic stress (PTS); secondary outcomes included symptoms of depression and overall behavioral adjustment. All assessments were conducted pretreatment, posttreatment, and 3 and 12 months after the end of treatment. Results showed improved scores on all outcomes posttreatment, sustained at 3 and 12 months. Effect sizes (Cohen's d) for baseline to posttreatment were 1.36 for child reported grief symptoms, 1.87 for child-reported PTS, and 1.15 for guardian report of child PTS.

Stress activates the hypothalamic–pituitary–adrenal (HPA) axis, which then modulates the degree of adaptation and response to a later stressor. It is known that early-life stress can impact on later health but less is known about how early-life stress impairs HPA axis activity, contributing to maladaptation of the stress–response system. Early-life stress exposure (either prenatally or in the early postnatal period) can impact developmental pathways resulting in lasting structural and regulatory changes that predispose to adulthood disease. Epidemiological, clinical, and experimental studies have demonstrated that early-life stress produces long term hyper-responsiveness to stress with exaggerated circulating glucocorticoids, and enhanced anxiety and depression-like behaviors. Recently, evidence has emerged on early-life stress-induced metabolic derangements, for example hyperinsulinemia and altered insulin sensitivity on exposure to a high energy diet later in life. This draws our attention to the contribution of later environment to disease vulnerability. Early-life stress can alter the expression of genes in peripheral tissues, such as the glucocorticoid receptor and 11-beta hydroxysteroid dehydrogenase (11β-HSD1). We propose that interactions between altered HPA axis activity and liver 11β-HSD1 modulates both tissue and circulating glucocorticoid availability, with adverse metabolic consequences. This review discusses the potential mechanisms underlying early-life stress-induced maladaptation of the HPA axis, and its subsequent effects on energy utilization and expenditure. The effects of positive later environments as a means of ameliorating early-life stress-induced health deficits, and proposed mechanisms underpinning the interaction between early-life stress and subsequent detrimental environmental exposures on metabolic risk will be outlined. Limitations in current methodology linking early-life stress and later health outcomes will also be

The concept of measuring the outcomes of treatment in health care was promoted by Ernest Amory Codman in the early 1900s, but, until recently, his ideas were generally ignored. The forces that have advanced outcome measurement to the forefront of health care include the shift in payers for health care from the patient to large insurance companies or government agencies, the movement toward assessing the care of populations not individuals, and the effort to find value (or cost-effective treatments) amid rising healthcare costs. No ideal method exists to measure outcomes, and the information gathered depends on the reason the outcome information is required. Outcome measures used in research are best able to answer research questions. The methods for assessing physician and hospital performance include process measures, patient-experience measures, structure measures, and measures used to assess the outcomes of treatment. The methods used to assess performance should be validated, be reliable, and reflect a patient's perception of the treatment results. The healthcare industry must measure outcomes to identify which treatments are most effective and provide the most benefit to patients.

The outcome for children with common surgical conditions that cause an acute abdomen is discussed. These conditions include appendicitis, intussusception, malrotation, inflammatory bowel disease, intestinal obstructions, and nonorganic pain. Emphasis is placed on surgical intervention and disease processes that significantly affect outcome. The outcome of many of the diseases discussed is strongly influenced by the timing of diagnosis and treatment. These children should have prompt care and intervention to prevent morbidity and mortality. In addition, many children who present with common pediatric surgical emergencies have other medical conditions and are best treated in an environment that has a multidisciplinary team to handle their care and decrease the long-term complications.

Child maltreatment has been linked with a number of risk behaviors that are associated with long-lasting maladaptive outcomes across multiple domains of functioning. This study examines whether the ages of onset of four risk behaviors-sexual intercourse, alcohol use, drug use, and criminal behavior-mediate the relationship between child maltreatment and outcomes in middle adulthood among a sample of court-documented victims of child abuse/neglect and matched controls (N = 1,196; 51.7% female; 66.2% White, 32.6% Black). Adult outcomes included employment status, welfare receipt, internalizing symptoms of anxiety and depressive symptoms, substance use problems, and criminal arrests. The results indicated gender differences in these relationships. For females, age of onset of sexual intercourse mediated the relationship between child abuse/neglect and both internalizing symptoms and substance use problems in middle adulthood. For males, age at first criminal arrest mediated the relationship between child abuse/neglect and extensive involvement in the justice system in middle adulthood. Age of onset of alcohol use and drug use did not mediate the relationship between child abuse/neglect and middle adult outcomes. This study expands current knowledge by identifying associations between early initiation of risk behavior in one domain and later, continuing problems in different domains. Thus, early initiation of specific risk behaviors may have more wide-ranging negative consequences than are typically considered during intervention or treatment and strategies may need to target multiple domains of functioning.

Previous research across species has shown that the amygdala is critical for learning about aversive outcomes, while the striatum is involved in reward-related processing. Less is known, however, about the role of the amygdala and the striatum in learning how to exert control over emotions and avoid negative outcomes. One potential mechanism for active avoidance of stressful situations is postulated to involve amygdala-striatal interactions. The goal of this study was to investigate the physiological and neural correlates underlying avoidance learning in humans. Specifically, we used a classical conditioning paradigm where three different conditioned stimuli (CS) were presented. One stimulus predicted the delivery of a shock upon stimulus offset (CS+), while another predicted no negative consequences (CS-). A third conditioned cue also predicted delivery of a shock, but participants were instructed that upon seeing this stimulus, they could avoid the shock if they chose the correct action (AV+). After successful learning, participants could then easily terminate the shock during subsequent stimulus presentations (AV-). Physiological responses (as measured by skin conductance responses) confirmed a main effect of conditioning, particularly showing higher arousal responses during pre (AV+) compared to post (AV-) learning of an avoidance response. Consistent with animal models, amygdala-striatal interactions were observed to underlie the acquisition of an avoidance response. These results support a mechanism of active coping with conditioned fear that allows for the control over emotional responses such as fears that can become maladaptive and influence our decision-making.

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age.

Teleophthalmology is gaining importance as an effective eye care delivery modality worldwide. In many developing countries, teleophthalmology is being utilized to provide quality eye care to the underserved urban population and the unserved remote rural population. Over the years, technological innovations have led to improvement in evidence and teleophthalmology has evolved from a research tool to a clinical tool. The majority of the current teleophthalmology services concentrate on patient screening and appropriate referral to experts. Specialty care using teleophthalmology services for the pediatric group includes screening as well as providing timely care for retinopathy of prematurity (ROP). Among geriatric eye diseases, specialty teleophthalmology care is focused toward screening and referral for diabetic retinopathy (DR), glaucoma, age-related macular degeneration (ARMD), and other sight-threatening conditions. Comprehensive vision screening and refractive error services are generally covered as part of most of the teleophthalmology methods. Over the past decades, outcome assessment of health care system includes patients’ assessments on their health, care, and services they receive. Outcomes, by and large, remain the ultimate validators of the effectiveness and quality of medical care. Teleophthalmology produces the same desired clinical outcome as the traditional system. Remote portals allow specialists to provide care over a larger region, thereby improving health outcomes and increasing accessibility of specialty care to a larger population. A high satisfaction level and acceptance is reported in the majority of the studies because of increased accessibility and reduced traveling cost and time. Considering the improved quality of patient care and patient satisfaction reported for these telemedicine services, this review explores how teleophthalmology helps to improve patient outcomes.

BACKGROUND Multiple randomized clinical trials comparing renal artery stent placement plus medical therapy with medical therapy alone have not shown any benefit of stent placement. However, debate continues whether patients with extreme pressure gradients, stenosis severity, or baseline blood pressure benefit from stent revascularization. OBJECTIVES The study sought to test the hypothesis that pressure gradients, stenosis severity, and/or baseline blood pressure affects outcomes after renal artery stent placement. METHODS Using data from 947 patients with a history of hypertension or chronic kidney disease from the largest randomized trial of renal artery stent placement, the CORAL (Cardiovascular Outcomes in Renal Atherosclerotic Lesions) study, we performed exploratory analyses to determine if subsets of patients experienced better outcomes after stent placement than the overall cohort. We examined baseline stenosis severity, systolic blood pressure, and translesion pressure gradient (peak systolic and mean) and performed interaction tests and Cox proportional hazards analyses for the occurrence of the primary endpoint through all follow-up, to examine the effect of these variables on outcomes by treatment group. RESULTS There were no statistically significant differences in outcomes based on the examined variables nor were there any consistent nonsignificant trends. CONCLUSIONS Based on data from the CORAL randomized trial, there is no evidence of a significant treatment effect of the renal artery stent procedure compared with medical therapy alone based on stenosis severity, level of systolic blood pressure elevation, or according to the magnitude of the transstenotic pressure gradient.

The study aimed to identify different patterns of gambling activities (PGAs) and to investigate how PGAs differed in gambling problems, substance use outcomes, personality traits and coping strategies. A representative sample of 4989 young Swiss males completed a questionnaire assessing seven distinct gambling activities, gambling problems, substance use outcomes, personality traits and coping strategies. PGAs were identified using latent class analysis (LCA). Differences between PGAs in gambling and substance use outcomes, personality traits and coping strategies were tested. LCA identified six different PGAs. With regard to gambling and substance use outcomes, the three most problematic PGAs were extensive gamblers, followed by private gamblers, and electronic lottery and casino gamblers, respectively. By contrast, the three least detrimental PGAs were rare or non-gamblers, lottery only gamblers and casino gamblers. With regard to personality traits, compared with rare or non-gamblers, private and casino gamblers reported higher levels of sensation seeking. Electronic lottery and casino gamblers, private gamblers and extensive gamblers had higher levels of aggression-hostility. Extensive and casino gamblers reported higher levels of sociability, whereas casino gamblers reported lower levels of anxiety-neuroticism. Extensive gamblers used more maladaptive and less adaptive coping strategies than other groups. Results suggest that gambling is not a homogeneous activity since different types of gamblers exist according to the PGA they are engaged in. Extensive gamblers, electronic and casino gamblers and private gamblers may have the most problematic PGAs. Personality traits and coping skills may predispose individuals to PGAs associated with more or less negative outcomes.
I have recently become involved in the ABET certification process under the new system - ABET 2000. This system relies heavily on concepts of Total Quality Management (TQM). It encourages each institution to define its objectives in terms of its own mission and then create a coherent program based on it. The prescribed steps in setting up the new system at an engineering institution are: o identification of constituencies G definition of mission. It is expected that the department's mission will be consistent with that of the overall institution, but containing some higher resolution language appropriate to that particular discipline of the engineering profession. o statement of objectives consistent with the mission 3G~~\\vED " enumeration of desired, and preferably measurable, outcomes of the process that would ~ `=. verify satisfaction of the objectives. ~~~ 07 !398 o establish performance standards for each outcome. o creation of appropriate feedback loops to assure that the objectives are still consistent with Q$YT1 the mission, that the outcomes remain consistent with the objectives, and that the curriculum and the teaching result in those outcomes. It is my assertion that once the institution verbalizes a mission, enumerated objectives naturally flow from that mission. (We shall try to demonstrate by example.) Further, if the mission uses the word "engineer", one would expect that word also to appear in at least one of the objectives. The objective of producing engineers of any sort must -by decree - involve the presence of the ABET criteria in the outcomes list. In other words, successful satisfaction of the ABET items a-k are a necessary subset of the measure of success in producing engineers. o We shall produce bachelor level engineers whose training in the core topics of chemical (or electrical, or mechanical) engineering is recognized to be among the best in the nation. o We shall provide an opportunity for our students to gain a

Contemporary associative learning research largely focuses on cue competition phenomena that occur when 2 cues are paired with a common outcome. Little research has been conducted to investigate similar phenomena occurring when a single cue is trained with 2 outcomes. Three conditioned lick suppression experiments with rats assessed whether treatments known to alleviate blocking between cues would also attenuate blocking between outcomes. In Experiment 1, conditioned responding recovered from blocking between outcomes when a long retention interval was interposed between training and testing. Experiment 2 obtained recovery from blocking between outcomes when the blocking outcome was extinguished after the blocking treatment. In Experiment 3, a recovery from blocking between outcomes occurred when a reminder stimulus was presented in a novel context prior to testing. Collectively, these studies demonstrate that blocking of outcomes, like blocking of cues, appears to be caused by a deficit in the expression of an acquired association.

In prematurely born children, various visual and ophthalmologic sequelae occur because of both retinopathy of prematurity (ROP) and preterm birth per se. Several long-term follow-up studies have described the outcome of ROP. Visual impairment and blindness are well-known consequences, but the prevalence varies globally because of differing neonatal and ophthalmologic care. Improving treatment options and criteria for the treatment of ROP are continuously changing the ophthalmologic outcome. The anatomic outcome has improved with treatment, but good anatomic outcome in treated severe ROP does not always reflect the functional outcome. There is no consensus regarding long-term follow-up of prematurely born children.

Introduction Methamphetamine (MA) is one of the most commonly used illicit drugs in pregnancy, yet studies on MA-exposed pregnancy outcomes have been limited because of retrospective measures of drug use, lack of control for confounding factors: other drug use, including tobacco; poverty; poor diet; and lack of prenatal care. This study presents prospective collected data on MA use and birth outcomes, controlling for most confounders. Materials and Methods This is a retrospective cohort study of women obtaining prenatal care from a clinic treating women with substance use disorders, on whom there are prospectively obtained data on MA and other drug use, including tobacco. MA-exposed pregnancies were compared with non-MA exposed pregnancies as well as non-drug exposed pregnancies, using univariate and multivariate analysis to control for confounders. Results One hundred forty-four infants were exposed to MA during pregnancy, 50 had first trimester exposure only, 45 had continuous use until the second trimester, 29 had continuous use until the third trimester, but were negative at delivery and 20 had positive toxicology at delivery. There were 107 non MA-exposed infants and 59 infants with no drug exposure. Mean birth weights were the same for MA-exposed and non-exposed infants (3159 g vs. 3168 g p=0.9), though smaller than those without any drug exposure (3159 vs. 3321 p=0.04), Infants with positive toxicology at birth (meconium or urine) were smaller than infants with first trimester exposure only (2932 g vs. 3300 g p=0.01). Gestation was significantly shorter among the MA-exposed infants compared to non-exposed infants (38.5 vs. 39.1 weeks p=0.045) and those with no drug exposure (38.5 vs. 39.5 p=0.0011), The infants with positive toxicology at birth had a clinically relevant shortening of gestation (37.3 weeks vs. 39.1 p=0.0002). Conclusions MA use during pregnancy is associated with shorter gestational ages and lower birth weight, especially if used continuously

Spirituality is a multifaceted construct that might affect veterans' recovery from posttraumatic stress disorder (PTSD) in adaptive and maladaptive ways. Using a cross-lagged panel design, this study examined longitudinal associations between spirituality and PTSD symptom severity among 532 U.S. veterans in a residential treatment program for combat-related PTSD. Results indicated that spirituality factors at the start of treatment were uniquely predictive of PTSD symptom severity at discharge, when accounting for combat exposure and both synchronous and autoregressive associations between the study variables, βs = .10 to .16. Specifically, veterans who scored higher on adaptive dimensions of spirituality (daily spiritual experiences, forgiveness, spiritual practices, positive religious coping, and organizational religiousness) at intake fared significantly better in this program. In addition, possible spiritual struggles (operationalized as negative religious coping) at baseline were predictive of poorer PTSD outcomes, β = .11. In contrast to these results, PTSD symptomatology at baseline did not predict any of the spirituality variables at posttreatment. In keeping with a spiritually integrative approach to treating combat-related PTSD, these results suggest that understanding the possible spiritual context of veterans' trauma-related concerns might add prognostic value and equip clinicians to alleviate PTSD symptomatology among those veterans who possess spiritual resources or are somehow struggling in this domain.

Background Respiratory symptoms are commonly used to assess the impact of patient-centered interventions. Objective At the request of National Institutes of Health (NIH) institutes and other federal agencies, an expert group was convened to propose which measurements of asthma symptoms should be used as a standardized measure in future clinical research studies. Methods Asthma symptom instruments were classified as daily diaries (prospectively recording symptoms between research visits) or retrospective questionnaires (completed at research visits). We conducted a systematic search in PubMed and a search for articles that cited key studies describing development of instruments. We classified outcome instruments as either core (required in future studies), supplemental (used according to study aims and standardized), or emerging (requiring validation and standardization). This work was discussed at an NIH-organized workshop in March 2010 and finalized in September 2011. Results Four instruments (3 daily diaries, 1 for adults and 2 for children; and 1 retrospective questionnaire for adults) were identified. Minimal clinically important differences have not been established for these instruments, and validation studies were only conducted in a limited number of patient populations. Validity of existing instruments may not be generalizable across racial-ethnic or other subgroups. Conclusions An evaluation of symptoms should be a core asthma outcome measure in clinical research. However, available instruments have limitations that preclude selection of a core instrument. The working group participants propose validation studies in diverse populations, comparisons of diaries versus retrospective questionnaires, and evaluations of symptom assessment alone versus composite scores of asthma control.

Delay discounting describes the tendency for organisms to devalue outcomes because they are delayed. Robust, positive correlations exist between excessive delay discounting and many maladaptive behaviors (e.g., substance abuse, obesity). Several studies have demonstrated that delay discounting can be reduced and this may hold promise for improving treatment outcomes. One method of reducing delay discounting provides rats with extended training with delayed reinforcement (i.e., delay-exposure training) and this significantly reduces impulsive choices, relative to rats trained with an equal number of immediate-reinforcement sessions (i.e., immediate-exposure training). To evaluate the stability of this effect, 12 weanling male Wistar rats were randomly assigned to receive either delay-exposure or immediate-exposure training for 120 sessions. Impulsive choice was assessed using an increasing-delay procedure immediately following training and 120 days after completion of the initial assessment. Delay-exposed rats discounted delayed food rewards significantly less than immediate-exposed rats in the initial assessment and the reassessment conducted 120 days later. These results are encouraging as they suggest that the effects of delay-exposure training are robust to the passage of time and intervening experience.
The survivors of the initial years of neonatal intensive care of preterm infants reached adulthood during the last decade. Reports of their adult outcomes examined have included neurodevelopmental, behavioral and health outcomes as well as social functioning and reproduction. Despite statistically significant differences between preterm young adults and controls in most outcomes studied, the majority of preterm survivors do well and live fairly normal lives. The two major predictors of adult outcomes are lower gestational age that reflect perinatal injury and family sociodemographic status which reflects both genetic and environmental effects.

Unfavourable outcomes are part and parcel of performing surgeries of any kind. Unfavourable outcomes are results of such work, which the patient and or the clinician does not like. This is an attempt to review various causes for unfavorable outcomes in orthognathic surgery and discuss them in detail. All causes for unfavorable outcomes may be classified as belonging to one of the following periods A) Pre- Treatment B) During treatment Pre-Treatment: In orthognathic surgery- as in any other discipline of surgery- which involves changes in both aesthetics and function, the patient motivation for seeking treatment is a very important input which may decide, whether the outcome is going to be favorable or not. Also, inputs in diagnosis and plan for treatment and its sequencing, involving the team of the surgeon and the orthodontist, will play a very important role in determining whether the outcome will be favorable. In other words, an unfavorable outcome may be predetermined even before the actual treatment process starts. During Treatment: Good treatment planning itself does not guarantee favorable results. The execution of the correct plan could go wrong at various stages which include, Pre-Surgical orthodontics, Intra and Post-Operative periods. A large number of these unfavorable outcomes are preventable, if attention is paid to detail while carrying out the treatment plan itself. Unfavorable outcomes in orthognathic surgery may be minimized If pitfalls are avoided both, at the time of treatment planning and execution. PMID:24501454

Purpose Provision of a wheelchair has immediate intuitive benefits; however, it can be difficult to evaluate which wheelchair and seating components best meet an individual’s needs. As well, funding agencies now prefer evidence of outcomes; and therefore measurement upon prescription of a wheelchair or its components is essential to demonstrate the efficacy of intervention. As no existing tool can provide individualized goal-oriented measure of outcome after wheelchair prescription, a research project was undertaken to create the Wheelchair Outcome Measure (WhOM). Method A mixed method research design was employed to develop the instrument, which used in-depth interviews of prescribers, individuals who use wheelchairs and their associates, supplemented by additional questions in which participant preferences in key areas of the measure were quantified. Results The WhOM is a client-specific wheelchair intervention measurement tool that is based on the World Health Organization’s International Classification of Function, Disability, and Health. It identifies desired outcomes at a participation level and also acknowledges concerns about body structure and function. Conclusion The new outcome instrument will allow clients to identify and evaluate the outcomes they wish to achieve with their wheelchairs and seating and provide clinicians a way to quantify outcomes of their interventions in a way that is meaningful to the client and potential funding sources.

The outcome of pediatric hydrocephalus, including surgical complications, neurological sequelae and academic achievement, has been the matter of many studies. However, much uncertainty remains, regarding the very long-term and social outcome, and the determinants of complications and clinical outcome. In this paper, we review the different facets of outcome, including surgical outcome (shunt failure, infection and independence, and complications of endoscopy), clinical outcome (neurological, sensory, cognitive sequels, epilepsy), schooling and social integration. We then provide a brief review of the English-language literature and highlighting selected studies that provide information on the outcome and sequelae of pediatric hydrocephalus, and the impact of predictive variables on outcome. Mortality caused by hydrocephalus and its treatments is between 0 and 3%, depending on the duration of follow-up. Shunt event-free survival (EFS) is about 70% at one year and 40% at ten years. The EFS after endoscopic third ventriculostomy (ETV) appears better but likely benefits from selection bias and long-term figures are not available. Shunt infection affects between 5 and 8% of surgeries, and 15 to 30% of patients according to the duration of follow-up. Shunt independence can be achieved in 3 to 9% of patients, but the definition of this varies. Broad variations in the prevalence of cognitive sequelae, affecting 12 to 50% of children, and difficulties at school, affecting between 20 and 60%, attest of disparities among studies in their clinical evaluation. Epilepsy, affecting 6 to 30% of patients, has a serious impact on outcome. In adulthood, social integration is poor in a substantial number of patients but data are sparse. Few controlled prospective studies exist regarding hydrocephalus outcomes; in their absence, largely retrospective studies must be used to evaluate the long-term consequences of hydrocephalus and its treatments. This review aims to help to establish
This paper attempts to answer the question: why does normal, goal-directed, purposeful, and coordinated behavior fragment in a survival situation? Events accompanying the initial impact phase of a survival incident are characterized by speed, danger, violence, and uncontrollability. The following recoil phase is known to produce behavioral and cognitive impairment that leads to a reduced ability to produce a response that is meaningful and may result in tonic immobility. The author argues that the commonly witnessed responses among survivors comprise a subset of known behaviors, including loss of initiative, stereotypy, perseveration of thought and action, hyperkinesia, hypokinesia, and, in extreme cases, akinesia or cognitive paralysis. These behaviors are characteristic of executive dysfunction and a model is given suggesting how this condition may arise under survival conditions. The case is presented that during the initial phase of a survival incident, victims show a transient, nonclinical dysexecutive syndrome. This model should aid survival training and provide a context for conducting behavioral autopsies by accident investigators.

Induction of anesthesia can be a very stressful period for a child and his family and can be associated with increased risk of psychological disturbances. These disturbances are categorized as preoperative anxiety, emergence delirium and postoperative behavioral changes. Several tools have been developed to measure these psychological manifestations as well as the baseline personality traits of these patients. Postoperative negative behavioral changes, such as sleep and eating disorders, separation anxiety, temper tantrum, aggression toward authorities, may occur in up to 60% of all children undergoing general anesthesia. Several studies found a strong association between these postoperative behavioral changes, the distress of the child on induction and his individual personality characteristics, although a cause-effect relationship could not be determined. Understanding the risk factors for behavior changes helps us determine the best way for prevention and treatment of these changes in the perioperative period.

Peripartum cardiomyopathy (PPCM) is a rare condition with a diverse spectrum of potential outcomes, ranging from frequent complete recovery to fulminant heart failure and death. The pathogenesis of PPCM is not well understood, and relatively little is known about its incidence and prevalence. PPCM is often under-recognised in the clinical setting. Early investigation and diagnosis with subsequent expert management may improve outcomes. The development of registries will allow this condition to be better characterised and may help answer crucial questions regarding its optimal medical and surgical management. This paper reviews the potential approaches to improve outcomes in patients with PPCM.

OBJECTIVES—The impact of stroke on the emotional outcome of patients is large. The aim was to describe the emotional outcomes among a cohort of patients which was of sufficient size to provide a precise estimate of their frequency and help identify those factors which are associated with poor outcomes after an acute stroke. METHODS—372 surviving patients, who had been referred to a hospital and entered into a randomised trial to evaluate a stroke family care worker, were asked to complete questionnaires at a 6 month follow up. These included measures of emotional distress (general health questionnaire 30 item, hospital anxiety and depression scale) and physical functioning (modified Rankin, Barthel index). A regression analysis was used to identify factors which were independently associated with poor outcomes. RESULTS—184 (60%) surviving patients scored more than 4 on the GHQ-30, 55 (22%) more than 8 on the HAD anxiety subscale, and 49 (20%) more than 8 on the HAD depression subscale. Patients with severe strokes resulting in physical disability were more likely to be depressed whereas there was a less strong relation between disability and anxiety. Patients with posterior circulation strokes had consistently better emotional outcomes than those with anterior circulation strokes. CONCLUSIONS—These data may help identify those patients at greatest risk of poor emotional outcomes and thus help in planning trials and delivering appropriate interventions. PMID:10601401

The Patient-Centered Outcomes Research Institute is funding 8 comparative effectiveness research projects to improve patient-centered outcomes for African American and Hispanic/Latino patients with uncontrolled asthma. These projects aim to compare multilevel interventions with known efficacy at the community, home, and health system levels to enhance patient and clinician uptake of the National Heart, Lung, and Blood Institute's National Asthma Education Prevention Program guidelines and improve outcomes. The National Asthma Education Prevention Program guidelines provide clinicians with a range of acceptable approaches for the diagnosis and management of asthma and define general practices that meet the needs of most patients. Yet disparities in asthma care and outcomes remain pervasive for African Americans and Hispanics/Latinos. The National Heart, Lung, and Blood Institute AsthmaNet consortium has identified several top research priorities for pediatric and adult populations, including a recommendation to examine tailored approaches based on race/ethnicity. In addition, the guidelines emphasize the need for studies that focus on multicomponent interventions recognizing that single interventions are generally ineffective. This article will describe the Patient-Centered Outcomes Research Institute-funded asthma projects and how they are individually and collectively addressing evidence gaps in asthma care by focusing on multicomponent and tailored approaches for improving outcomes and reducing disparities for African American and Hispanic/Latino patients.

Osteoarthritis (OA) is one of the most frequently occurring musculoskeletal diseases, posing a significant public health problem due to its impact on pain and disability. Traditional risk factors fail to account for all of the risk observed for OA outcomes. In recent years, our view of disease causation has broadened to include health risks that are created by an individual’s socioeconomic circumstances. Early research into social determinants has focused on social position and explored factors related to the individual such as education, income and occupation. Results from these investigations suggest that low education attainment and nonprofessional occupation are associated with poorer arthritis outcomes. More recently, research has expanded to examine how one’s neighborhood socioeconomic environment may be relevant to OA outcomes. This narrative review proposes a framework to help guide our understanding of how social context may interact with pathophysiological processes and individual-level variables to influence health outcomes in those living with OA.

The toxicological effects of many stressors are mediated through unknown, or poorly characterized, mechanisms of action. We describe the application of reverse engineering complex interaction networks from high dimensional omics data (gene, protein, metabolic, signaling) to characterize adverse outcome pathways (AOPs) for chemicals that disrupt the hypothalamus-pituitary-gonadal endocrine axis in fathead minnows. Gene expression changes in fathead minnow ovaries in response to 7 different chemicals, over different times, doses, and in vivo versus in vitro conditions were captured in a large data set of 868 arrays. We examined potential AOPs of the antiandrogen flutamide using two mutual information theory methods, ARACNE and CLR to infer gene regulatory networks and potential adverse outcome pathways. Representative networks from these studies were used to predict a network path from stressor to adverse outcome as a candidate AOP. The relationship of individual chemicals to an adverse outcome can be determined by following perturbations through the network in response to chemical treatment leading to the nodes associated with the adverse outcome. Identification of candidate pathways allows for formation of testable hypotheses about key biologic processes, biomarkers or alternative endpoints, which could be used to monitor an adverse outcome pathway. Finally, we identify the unique challenges facing the application of this approach in ecotoxicology, and attempt to provide a road map for the utilization of these tools. Key Words: mechanism of action, toxicology, microarray, network inference

Why does self-control predict such a wide array of positive life outcomes? Conventional wisdom holds that self-control is used to effortfully inhibit maladaptive impulses, yet this view conflicts with emerging evidence that self-control is associated with less inhibition in daily life. We propose that one of the reasons individuals with better self-control use less effortful inhibition, yet make better progress on their goals is that they rely on beneficial habits. Across 6 studies (total N = 2,274), we found support for this hypothesis. In Study 1, habits for eating healthy snacks, exercising, and getting consistent sleep mediated the effect of self-control on both increased automaticity and lower reported effortful inhibition in enacting those behaviors. In Studies 2 and 3, study habits mediated the effect of self-control on reduced motivational interference during a work-leisure conflict and on greater ability to study even under difficult circumstances. In Study 4, homework habits mediated the effect of self-control on classroom engagement and homework completion. Study 5 was a prospective longitudinal study of teenage youth who participated in a 5-day meditation retreat. Better self-control before the retreat predicted stronger meditation habits 3 months after the retreat, and habits mediated the effect of self-control on successfully accomplishing meditation practice goals. Finally, in Study 6, study habits mediated the effect of self-control on homework completion and 2 objectively measured long-term academic outcomes: grade point average and first-year college persistence. Collectively, these results suggest that beneficial habits-perhaps more so than effortful inhibition-are an important factor linking self-control with positive life outcomes.

Aims To examine the relationship between personality, pregnancy and birth outcomes in adolescents Background Personality has been shown to be a strong predictor of many health outcomes. Adolescents who become pregnant have worse birth outcomes than adults. Design Cross-sectional study using data from the National Longitudinal Study of Adolescent Health (baseline, 1994-1995; follow-up, 2007-2008). Methods The study sample was 6529 girls, 820 of whom reported on pregnancy outcomes for a teenage birth. Personality data was taken from the Mini International Personality Item Pool personality tool, which measures the five-factor personality traits of neuroticism, conscientiousness, intellect/imagination, extraversion and agreeableness. Logistic regression was used to predict teen pregnancy and linear regression was used to predict birth weight and gestational age with adjustment for confounders and stratification by race. Results Agreeableness and intellect/imagination were associated with a reduced likelihood of becoming pregnant as an adolescent, while neuroticism, conscientiousness and extraversion were all associated with an increased likelihood of becoming pregnant. Higher neuroticism was associated with lower birth weight and gestational age among Black girls, but not non-Black. Conscientiousness was associated with lower gestational age among non-Black girls. No relationships were found with extraversion or agreeableness and birth outcomes. Receiving late or no prenatal care was associated with higher intellect/imagination. Conclusions Personality is understudied with respect to pregnancy and birth outcomes compared with other health outcomes. Such research could help professionals and clinicians design and target programs that best fit the characteristics of the population most likely to need them, such as those with high neuroticism.

In this paper, we report our experience from a prospective study in 40 ischemic stroke patients admitted during the last two years at University Department of Neurology Stroke Unit, Banja Luka Clinical Center, in order to assess the safety and efficacy of thrombolytic therapy, the impact of age, sex and risk factors, and functional outcome at 6 months of intravenous tissue plasminogen activator treatment. According to the National Institutes of Health Stroke Scale, there were 5 mild, 22 moderate and 13 severe stroke cases in the study group. The outcome measures at 6 months of thrombolytic treatment were taken in 38 (100%) patients, yielding a Functional Independent Measure score > or=90 (good clinical outcome) in 21 (52.50%) and modified Rankin Score < or =2 (good clinical outcome) in 22 (55%) patients. The rate of symptomatic intracerebral hemorrhage in tissue plasminogen activator treated patients was 5%, with a mortality rate of 17.50%. The outcomes were comparable with those found in the NINDS t-PA trial. Current guidelines recommend a 'door-to-needle' time of less than 60 minutes and emphasize that 'time is brain'.

Recent literature has already embraced the topic of endoscopic septoplasty, with several published articles on the subject. This approach provides a direct-targeted route to the anatomic deformity, improved visualization, and magnification of the surgical field. It allows improved evaluation of the posterior nasal septal deformities, identification of the degree of mucosal involvement of the posterior ends of the inferior turbinates, and concomitant assessment of the middle meatus. It permits objective documentation of the cause of nasal obstruction with possible use in outcome assessment. It is also an effective teaching method and a motivating approach for the nursing team. We present our experience in a series of 47 patients performed during a 1 1/2-year period and discuss the surgical technique and patients' outcomes. We systematically used the endoscope for all septal and turbinate surgery. We evaluated outcomes using a telephone survey along with a validated disease-specific health status measure and a global rating questionnaire.

A number of studies have revealed that low birth weight children have a heightened risk of various maladaptive outcomes, including academic challenges and delinquent involvement. However, very little research to date has examined whether the relationship between low birth weight, poor academic performance, and delinquent peer affiliation is moderated by genetic risk. Using data from the National Longitudinal study of Adolescent Health, the present study examines whether male adolescents born at very low birth weights are significantly predisposed to poor academic performance and delinquent peer affiliation. Moreover, we test whether the effect of birth weight on these outcomes is conditioned by level of genetic risk. We find no evidence that very low birth weight males are more likely to affiliate with delinquent peers or perform poorly in school during adolescence. However, upon examining gene-environment interactions, we find that being born at a very low birth weight does significantly increase the odds of poor academic performance and delinquent peer affiliation among males who possess a higher level of genetic risk. Limitations are noted and the implications of the findings are discussed.

Endoscopic ear surgery (EES) provides several advantages compared with traditional binocular microscopy, including a wide-field view, improved resolution with high magnification, and visual access to hidden corridors of the middle ear. Although binocular microscopic-assisted surgical techniques remain the gold standard for most otologists, EES is slowly emerging as a viable alternative for performing otologic surgery at several centers in the United States and abroad. In this review, we evaluate the current body of literature regarding EES outcomes, summarize our EES outcomes at the Massachusetts Eye and Ear Infirmary, and compare these results with data for microscopic-assisted otologic surgery.

The neural mechanisms underlying recovery of language after left hemisphere stroke remain elusive. Although older evidence suggested that right hemisphere language homologues compensate for damage in left hemisphere language areas, the current prevailing theory suggests that right hemisphere engagement is ineffective or even maladaptive. Using a novel combination of support vector regression-based lesion-symptom mapping and voxel-based morphometry, we aimed to determine whether local grey matter volume in the right hemisphere independently contributes to aphasia outcomes after chronic left hemisphere stroke. Thirty-two left hemisphere stroke survivors with aphasia underwent language assessment with the Western Aphasia Battery-Revised and tests of other cognitive domains. High-resolution T1-weighted images were obtained in aphasia patients and 30 demographically matched healthy controls. Support vector regression-based multivariate lesion-symptom mapping was used to identify critical language areas in the left hemisphere and then to quantify each stroke survivor's lesion burden in these areas. After controlling for these direct effects of the stroke on language, voxel-based morphometry was then used to determine whether local grey matter volumes in the right hemisphere explained additional variance in language outcomes. In brain areas in which grey matter volumes related to language outcomes, we then compared grey matter volumes in patients and healthy controls to assess post-stroke plasticity. Lesion-symptom mapping showed that specific left hemisphere regions related to different language abilities. After controlling for lesion burden in these areas, lesion size, and demographic factors, grey matter volumes in parts of the right temporoparietal cortex positively related to spontaneous speech, naming, and repetition scores. Examining whether domain general cognitive functions might explain these relationships, partial correlations demonstrated that grey matter

Canada is a federal country of 10 provinces and three territories. High level information on mental health conditions and service use has mostly been generated from administrative data collected by provinces and territories. These include four major types - hospital admissions and discharges, physician billings, ambulatory care services, and drug databases. At the national level, the Canadian Institute for Health Information brings together this information to produce indicators of outcome. Although these data provide information on patient and health system characteristics, they do not capture the full spectrum of formal and informal mental healthcare. These include changes in health status, functioning, community integration and quality of life. As a result, some jurisdictions have begun to implement more standardized measures of outcome such as the clinician-rated Health of the Nation Outcome Scales or the inpatient Resident Assessment Instrument - Mental Health. In this paper we provide an overview of mental-health-related data sources in Canada, highlight some of the more progressive practices beginning to emerge, and conclude with some thoughts about how the routine measurement and reporting of mental health outcomes in Canada might be advanced including efforts at engaging both clinicians and decision-makers.

Children (0-18 years) with maltreatment histories are vulnerable to experiencing difficulties across multiple domains of functioning, including educational outcomes that encompass not only academic achievement but also mental well-being. The current literature review adopted Slade and Wissow's model to examine (1) the link between childhood maltreatment and academic achievement, (2) the link between childhood maltreatment and mental health outcomes (i.e., emotional and behavioral difficulties), and (3) the bidirectional relationship between childhood academic achievement and mental health. In addition, we reviewed variables that might influence or help explain the link between childhood maltreatment and educational outcomes, drawing on developmental perspectives and Bronfenbrenner's ecological model. Finally, whenever possible, we presented findings specific to maltreated children in out-of-home care to highlight the unique challenges experienced by this population. Results indicated that children with maltreatment histories often experience impairments in both their academic performance (e.g., special education, grade retention, lower grades) and mental well-being (e.g., anxiety, low mood, aggression, social skills deficits, poor interpersonal relationships). These impairments appeared to be particularly pronounced among maltreated children in out-of-home care. Findings, albeit sparse, also indicated that mental health difficulties are negatively associated with children's academic achievement and, similarly, that academic achievement deficits are linked with mental health problems. The link between childhood maltreatment and educational outcomes may be partly explained through the disruption of key developmental processes in children, such as attachment, emotion regulation, and sense of agency. As well, maltreatment characteristics and the functioning of various systems in which children are embedded (e.g., family, school, child welfare) can serve to positively

Renal disease management organizations have reported achieving significant decreases in mortality and hospitalization in conjunction with cost savings, improved patient satisfaction and quality of life. Disease management organizations strive to fill existing gaps in care delivery through the standardized use of risk assessment, predictive modeling, evidence based guidelines and process and outcomes measurement. Patient self-management education and the provision of individual nurse care managers are also key program components. As we more fully measure clinical outcomes and total health-care costs including payments from all insurance and government entities, pharmacy costs and out-of-pocket expenditures, the full implications of disease management can be better defined. The results of this analysis will have a profound influence on United States healthcare policy. At present, current data suggests that the promise of disease management, improved care at reduced cost, can and is being realized in ESRD.

There is emerging evidence related to the effects of nitrous oxide on important perioperative patient outcomes. Proposed mechanisms include metabolic effects linked to elevated homocysteine levels and endothelial dysfunction, inhibition of deoxyribonucleic acid and protein formation, and depression of chemotactic migration by monocytes. Newer large studies point to possible risks associated with the use of nitrous oxide, although data are often equivocal and inconclusive. Cardiovascular outcomes such as stroke or myocardial infarction were shown to be unchanged in previous studies, but the more recent Evaluation of Nitrous Oxide in the Gas Mixture for Anesthesia I trial shows possible associations between nitrous oxide and increased cardiovascular and pulmonary complications. There are also possible effects on postoperative wound infections and neuropsychological function, although the multifactorial nature of these complications should be considered. Teratogenicity linked to nitrous oxide use has not been firmly established. The use of nitrous oxide for routine anesthetic care may be associated with significant costs if complications such as nausea, vomiting, and wound infections are taken into consideration. Overall, definitive data regarding the effect of nitrous oxide on major perioperative outcomes are lacking. There are ongoing prospective studies that may further elucidate its role. The use of nitrous oxide in daily practice should be individualized to each patient's medical conditions and risk factors.

The origin of liposuction can be traced to an adverse event by Dujarrier in 1921 when he used a uterine curette to remove fat from the knees of a ballerina ending in an amputation secondary to damage of the femoral artery. The history of liposuction since then has been one of avoiding complications and optimising outcome. After this adverse event, liposuction was abandoned until the 1960's when Schrudde revived the practice using small stab incisions and sharp curettage with the secondary suction to aspirate the freed tissue. This technique was associated with a high incidence of complications especially seroma and skin necrosis. Illouz then replaced the curette with a blunt cannula connected to vacuum pump thus avoiding the complications of a sharp curette. Despite the presence of various techniques for liposuction, suction assisted liposuction (SAL) is still the standard technique of liposuction. This article aims to discuss literature regarding the various aspects of liposuction (SAL) and to highlight the salient points in the literature and in the senior author's experience in order to avoid unfavourable outcomes in liposuction. A literature review on avoiding complication is in liposuction including some of the seminal papers on liposuction. Liposuction is generally a safe procedure with reproducible outcome. Just like any surgical procedure it should be treated with the utmost care. Illouz published 10 commandments for liposuction in 1989 and we review these commandments to demonstrate how liposuction has evolved. PMID:24501475

Optimal transplantation strategies are uncertain in primary hyperoxaluria (PH) due to potential for recurrent oxalosis. Outcomes of different transplantation approaches were compared using life table methods to determine kidney graft survival among 203 patients in the International Primary Hyperoxaluria Registry. From 1976–2009, 84 kidney alone (K) and combined kidney and liver (K+L) transplants were performed in 58 patients. Among 58 first kidney transplants (32 K, 26 K+L), 1, 3, and 5 year kidney graft survival was 82%, 68%, and 49%. Renal graft loss occurred in 26 first transplants due to oxalosis in 10, chronic allograft nephropathy in 6, rejection in 5, and other causes in 5. Delay in PH diagnosis until after transplant favored early graft loss (p=0.07). K+L had better kidney graft outcomes than K with death censored graft survival 95% vs. 56% at 3yrs (p=.011). Among 29 year 2000–09 first transplants (24 K+L), 84% were functioning at 3 years compared to 55% of earlier transplants (p=0.05). At 6.8 years after transplantation, 46 of 58 patients are living (43 with functioning grafts). Outcomes of transplantation in PH have improved over time, with recent K+L transplantation highly successful. Recurrent oxalosis accounted for a minority of kidney graft losses. PMID:20849551

Outcomes management as a patient management system has been designed to impact and improve select outcomes. Central to the development and implementation of best practice senario identified throughout outcomes management is the advanced practice nurse. SLEH has been in the forefront of development and implementation of an outcomes management program. This article describes the outcomes management position and shares the job description and performance evaluation used at this institution. The tools allow for measuring and quantifying the impact of the outcomes manager position on improving patient outcomes. The improvement of outcomes has increased the value of the advanced practice nurse and provided the institution with a solid future necessary for survival in a managed care market.

Background Esophagectomy is a complex operation and is associated with significant morbidity and mortality. In an attempt to lower morbidity, we have adopted a minimally invasive approach to esophagectomy. Objectives Our primary objective was to evaluate the outcomes of minimally invasive esophagectomy (MIE) in a large group of patients. Our secondary objective was to compare the modified McKeown minimally invasive approach (videothoracoscopic surgery, laparoscopy, neck anastomosis [MIE-neck]) with our current approach, a modified Ivor Lewis approach (laparoscopy, videothoracoscopic surgery, chest anastomosis [MIE-chest]). Methods We reviewed 1033 consecutive patients undergoing MIE. Elective operation was performed on 1011 patients; 22 patients with nonelective operations were excluded. Patients were stratified by surgical approach and perioperative outcomes analyzed. The primary endpoint studied was 30-day mortality. Results The MIE-neck was performed in 481 (48%) and MIE-Ivor Lewis in 530 (52%). Patients undergoing MIE-Ivor Lewis were operated in the current era. The median number of lymph nodes resected was 21. The operative mortality was 1.68%. Median length of stay (8 days) and ICU stay (2 days) were similar between the 2 approaches. Mortality rate was 0.9%, and recurrent nerve injury was less frequent in the Ivor Lewis MIE group (P < 0.001). Conclusions MIE in our center resulted in acceptable lymph node resection, postoperative outcomes, and low mortality using either an MIE-neck or an MIE-chest approach. The MIE Ivor Lewis approach was associated with reduced recurrent laryngeal nerve injury and mortality of 0.9% and is now our preferred approach. Minimally invasive esophagectomy can be performed safely, with good results in an experienced center. PMID:22668811

AIM: To conduct a review of the telepsychiatry literature. METHODS: We conducted a systematic search of the literature on telepsychiatry using the search terms, “telepsychiatry”, “telemental health”, “telecare”, “telemedicine”, “e-health”, and “videoconferencing”. To meet criteria for inclusion, studies had to: (1) be published in a peer-reviewed journal after the year 2000; (2) be written in English; (3) use videoconferencing technology for the provision of mental health assessment or treatment services; and (4) use an adequately-powered randomized controlled trial design in the case of treatment outcome studies. Out of 1976 studies identified by searches in PubMed (Medline database), Ovid medline, PsychInfo, Embase, and EBSCO PSYCH, 452 met inclusion criteria. Studies that met all inclusion criteria were organized into one of six categories: (1) satisfaction; (2) reliability; (3) treatment outcomes; (4) implementation outcomes; (5) cost effectiveness; and (6) and legal issues. All disagreements were resolved by reassessing study characteristics and discussion. RESULTS: Overall, patients and providers are generally satisfied with telepsychiatry services. Providers, however, tend to express more concerns about the potentially adverse of effects of telepsychiatry on therapeutic rapport. Patients are less likely to endorse such concerns about impaired rapport with their provider. Although few studies appropriately employ non-inferiority designs, the evidence taken together suggests that telepsychiatry is comparable to face-to-face services in terms of reliability of clinical assessments and treatment outcomes. When non-inferiority designs were appropriately used, telepsychiatry performed as well as, if not better than face-to-face delivery of mental health services. Studies using both rudimentary and more sophisticated methods for evaluating cost-effectiveness indicate that telepsychiatry is not more expensive than face-to-face delivery of

The goal of fine-tuning bunion surgery is to optimize outcomes and prevent complications. This is accomplished through restoring anatomic alignment, imparting first ray stability, meticulous surgical technique, and accounting for other causes that may contribute to first ray instability. Despite various soft tissue and osseous surgical procedures along with anatomic variations of each patient, the principles of anatomic restoration and stability remain consistent. Maintenance of correction is predicated on the treatment of underlying pathology and the establishment of optimal stability and first ray alignment.

Despite an appreciation for many unwanted physiological effects from inadequate pain postoperative relief, moderate to severe postoperative pain remains commonplace. Though treatment options have evolved in recent years, including improvement in medications, multimodal regimens, and regional anesthetic techniques, including ultrasound and continuous catheters, outcomes data indicate that many of these strategies are associated with varying degrees of morbidity and mortality. This review focuses on the importance of effective postoperative analgesia and both short- and long-term effects associated with inadequate management. A careful literature review of emphasizing treatment options and potential pathogenesis associated with these strategies is emphasized in this review.

Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for 7 years and is now approximately 11.39%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23 to 24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal estimated date of confinement. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (<1000 g) remain at high risk for death and disability with 30% to 50% mortality and, in survivors, at least 20% to 50% risk of morbidity. The introduction of continuous positive airway pressure, mechanical ventilation, and exogenous surfactant increased survival and spurred the development of neonatal intensive care in the 1970s through the early 1990s. Routine administration of antenatal steroids during premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91% and 95% (compared with 85%-89%) avoids excess mortality; however, final analyses of data from these trials have not been published, so definitive recommendations are still pending. The development of neonatal neurocritical intensive care units may improve neurocognitive outcomes in this high-risk group. Long-term follow-up to detect and address

Group forms of therapy have been growing at a rapid rate, in part because of their documented effectiveness and economic considerations such as managed care. It is therefore becoming increasingly important to assess the psychological risks of these interventions. The author provides an overview of the published literature and conference presentations on negative effects in adult outpatient groups. Although much of the literature on adverse outcomes in group therapy focuses on single risk factors (e.g., negative leader, group process, or patient characteristics), the author argues that an interactional model should be encouraged. Means of reducing casualties are also discussed, as well as methodological issues and research directions. PMID:10896735

Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for four years and is now approximately 11.5%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23–24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal EDC. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (ELBW) (< 1000 grams) remain at high risk for death and disability with 30–50% mortality and, in survivors, at least 20–50% risk of morbidity. The introduction of CPAP, mechanical ventilation, and exogenous surfactant increased survival and spurred the development of neonatal intensive care in the 1970s through the early 1990s.

There are few empirical studies of the adult outcomes of nonverbal learning disability (NLD). An overwhelming majority of NLD studies has been devoted to the nature of academic difficulties of school children, whereas the few follow-up studies have tended to be limited to college-age young adults. Herein, it is argued that the problems of adults with NLD do not fall solely in academic areas, and that early academic remediation programs might do well to include intervention in emotional and social skills enhancement.

Almost fifty million people are food insecure in the United States, which makes food insecurity one of the nation's leading health and nutrition issues. We examine recent research evidence of the health consequences of food insecurity for children, nonsenior adults, and seniors in the United States. For context, we first provide an overview of how food insecurity is measured in the country, followed by a presentation of recent trends in the prevalence of food insecurity. Then we present a survey of selected recent research that examined the association between food insecurity and health outcomes. We show that the literature has consistently found food insecurity to be negatively associated with health. For example, after confounding risk factors were controlled for, studies found that food-insecure children are at least twice as likely to report being in fair or poor health and at least 1.4 times more likely to have asthma, compared to food-secure children; and food-insecure seniors have limitations in activities of daily living comparable to those of food-secure seniors fourteen years older. The Supplemental Nutrition Assistance Program (SNAP) substantially reduces the prevalence of food insecurity and thus is critical to reducing negative health outcomes.

Objective To determine if arrhythmia in the setting of maternal cardiac disease (MCD) affects perinatal outcomes. Study Design This is a retrospective cohort study of pregnant women with MCD who delivered from 2008 to 2013. Perinatal outcomes among women with an arrhythmia were compared to those without. Result Among 143 women; 36 (25%) had an arrhythmia. Those with an arrhythmia were more likely to have a spontaneous vaginal delivery (64% vs. 43%, p < 0.05) and required fewer operative vaginal births (8% vs. 27%, p=0.02). Pregnancies were more likely to be complicated by IUGR (17% vs. 5%, p < 0.05) although there were no differences in the rate of small for gestational age. The risk of IUGR remained increased after controlling for confounding (aOR 6.98, 95% CI 1.59–30.79, p=0.01). Two cases of placental abruption were identified among mothers with arrhythmia while none were identified in the controls (p < 0.05) Conclusion Patients with arrhythmias were more likely to have a spontaneous vaginal delivery. Our data suggests that these pregnancies were an increased risk for IUGR. PMID:27309629

OBJECTIVE To compare maternal outcomes of cesarean sections performed by GPs with the outcomes of those performed by specialists. DESIGN Retrospective, comorbidity-adjusted study. SETTING Mostly small isolated rural hospitals in Ontario, British Columbia, Alberta, and Saskatchewan compared with all levels of specialist obstetric programs offered in Canada. PARTICIPANTS Fifteen GPs with less than 1 year of surgical training who performed cesarean sections. METHOD Using data from the Canadian Institute for Health Information’s Discharge Abstracts Database for the years 1990 to 2001, we matched each of 1448 cesarean section cases managed by these GPs to 3 cases managed by specialists and looked for comorbidity. In total, we analyzed the outcomes of 5792 cesarean sections. MAIN OUTCOME MEASURES Composites of major morbidity possibly attributable to surgery:death, sepsis, cardiac arrest, shock, hypotension, ileus or bowel obstruction,major puerperal infection, septic or fat embolism, postpartum hemorrhage requiring hysterectomy, need for cardiopulmonary resuscitation, or another operation; and all major morbidity: major surgical morbidity, acute coronary syndrome, endocarditis, pulmonary edema, cerebrovascular disorder, pneumothorax, respiratory failure, amniotic fluid embolism, complications of anesthesia, deep vein thrombosis, pulmonary embolism, acute renal failure, and need for mechanical ventilation. RESULTS The rate of all major morbidity was higher among GPs’ patients than among specialists’ patients (3.1% vs 1.9%, odds ratio [OR] 1.6, 95% confidence interval [CI] 1.1 to2.3, P = .009) as was the rate of major surgical morbidity (2.5% vs 1.6%, OR 1.6, 95% CI 1.1 to 2.4, P = .024). Differences in major morbidity variables were not significant if major postpartum infection was excluded (all major morbidity 1.5% vs 1.1%, major surgical morbidity 1.0% vs 0.8%). Secondary outcomes included rate of transfer to acute care institutions (6.0% vs 1.5%, OR 4.6, 95% CI

We extend the recently proposed "tradeoff model" of intertemporal choice (Scholten & Read, 2010) from choices between pairs of single outcomes to pairwise choices involving two-outcome sequences. The core of our proposal is that choices between sequences are made by weighing accumulated outcomes against outcome-adjusted delays. Thus extended, the…

Learning outcomes define the veterinary curriculum and inform students about what they must be able to demonstrate to succeed. Stakeholder consultation during their development ensures that programme learning outcomes equip graduates to contribute to the veterinary profession. Effective learning outcomes form a hierarchy linking the programme, its courses and tasks. Clear outcomes direct students towards higher quality learning by indicating the achievements intended, but leave scope for emergent learning outcomes. Defined technical competencies fit within this overarching framework, complementing higher order learning. Mapping is used to align learning outcomes horizontally and vertically so students are systematically guided towards entry-level competence and professional independence. Constructively aligned learning and assessment tasks ensure learners spend the focused time required to sequentially develop programme outcomes. Assessment by staff, peers and other stakeholders certifies achievement of intended outcomes. Effective assessment also empowers students to define and achieve their own learning outcomes, so they develop the habits of autonomous life-long learning. Evaluation of the quality and consistency of achieved outcomes informs ongoing programme improvement. If we are going to achieve the objectives of this set of papers, i.e. to improve public health education globally (Rev. sci. tech. Off. int. Epiz. 28  2009), then it is essential that they be well defined in the learning outcomes statement of all veterinary schools.
Inflammatory rheumatic diseases are generally multifaceted disorders and, therefore, measurement of multiple outcomes is relevant to most of these diseases. Developments in outcome measures in the rheumatic diseases are promoted by the development of successful treatments. Outcome measurement will increasingly deal with measurement of low levels of disease activity and avoidance of disease consequences. It is an advantage for patient management and knowledge transfer if the same outcomes are used in practice and in trials. Continuous measures of change are generally the most powerful and, therefore, are preferred as primary outcomes in trials. For daily clinical practice, outcome measures should reflect the patients' state and have to be easily derivable. The objective of this review is to describe recent developments in outcome measures for inflammatory rheumatic diseases for trials and clinical practice, with an emphasis on rheumatoid arthritis.

The high-level athletic population poses difficulty when evaluating outcomes in orthopedic surgery, given generally good overall health and high function at baseline. Subtle differences in performance following injury or orthopedic surgery are hard to detect in high-performance athletes using standard outcome metrics; however, attaining these subtle improvements after injury or surgery are key to an athletes' livelihood. Outcome measures serve as the cornerstone for critical evaluation of clinical outcomes following orthopedic surgery or injury. In the age of "evidence-based medicine" and "pay-for-performance" accountability for surgical intervention, understanding clinically relevant outcome measures is essential for careful review of the published literature, as well as one's own critical review of surgical performance. The purpose of this manuscript is to evaluate clinical outcome measures in the context of the athletic elbow. An emphasis will be placed on evaluation of the 5 most clinically relevant outcome measures for sports-related elbow outcomes: (1) American Shoulder and Elbow Committee; (2) Mayo Elbow Performance Index; (3) Andrews-Timmerman [and its precursor the (4) Andrews-Carson]; and (5) Kerlan-Jobe Orthopaedic Clinic overhead athlete score. A final outcome measure that will be analyzed is "return to play" statistics, which has been published in various studies of athletes' recovery from elbow surgery, as well as, the outcomes metric known as the "Conway-Jobe scale." Although there is no perfect outcomes score for the athletic elbow, the Kerlan-Jobe Orthopaedic Clinic score is the only outcomes tool developed and validated for outcomes for elbow injuries in the overhead athlete, as compared with the Andrew-Timmerman and Conway-Jobe metrics, which were not validated outcome measures for the elbow in this patient population. Despite the Disabilities of Arm, Shoulder, Hand (DASH) (and DASH-Sport module) being validated in the general population, this

Gallbladder cancer, though generally considered rare, is the most common malignancy of the biliary tract, accounting for 80%–95% of biliary tract cancers. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis, often proving fatal. Its carcinogenesis follows a progression through a metaplasia–dysplasia–carcinoma sequence. This comprehensive review focuses on and explores the risks, management, and outcomes for primary gallbladder carcinoma. Epidemiological studies have identified striking geographic and ethnic disparities – inordinately high occurrence in American Indians, elevated in Southeast Asia, yet quite low elsewhere in the Americas and the world. Age, female sex, congenital biliary tract anomalies, and a genetic predisposition represent important risk factors that are immutable. Environmental triggers play a critical role in eliciting cancer developing in the gallbladder, best exemplified by cholelithiasis and chronic inflammation from biliary tract and parasitic infections. Mortality rates closely follow incidence; those countries with the highest prevalence of gallstones experience the greatest mortality from gallbladder cancer. Vague symptoms often delay the diagnosis of gallbladder cancer, contributing to its overall progression and poor outcome. Surgery represents the only potential for cure. Some individuals are fortunate to be incidentally found to have gallbladder cancer at the time of cholecystectomy being performed for cholelithiasis. Such an early diagnosis is imperative as a late presentation connotes advanced staging, nodal involvement, and possible recurrence following attempted resection. Overall mean survival is a mere 6 months, while 5-year survival rate is only 5%. The dismal prognosis, in part, relates to the gallbladder lacking a serosal layer adjacent to the liver, enabling hepatic invasion and metastatic progression. Improved imaging modalities are helping to diagnose patients at an earlier

Successful pregnancies have been reported in all types of solid-organ transplant recipients on a variety of immunosuppressive regimens. Immunosuppression is essential to maintain the transplanted organ and maternal health, thus the safety of these medications continues to be studied. This article reviews information in the literature and data from the National Transplantation Pregnancy Registry (NTPR) in the United States related to immunosuppressive medication and pregnancy. Although most maintenance immunosuppressive regimens have not been shown to affect the outcome of posttransplant pregnancies, mycophenolic acid products are associated with an increased incidence of spontaneous abortion and an increase in the incidence and a specific pattern of birth defects. When counseling transplant recipients about the prospect and safety of pregnancy, the health of the mother, her graft, and the developing fetus must all be taken into account.

The authors address the hospital outcomes of patient satisfaction, healthcare quality, and net income per bed. They define union density as the percentage of a hospital's employees who are in unions, healthcare quality as its 30-day acute myocardial infraction (AMI; heart attack) mortality rate, and patient satisfaction as its overall Hospital Consumer Assessment of Healthcare Providers and Systems score. Using a random sample of 84 union and 84 nonunion hospitals from across the United States, multiple regression analyses show that union density is negatively related to patient satisfaction. Union density is not related to healthcare quality as measured by the AMI mortality rate or to net income per bed. This implies that unions per se are not good or bad for hospitals. The authors suggest that it is better for hospital administrators to take a Balanced Scorecard approach and be concerned about employee satisfaction, patient satisfaction, healthcare quality, and net income.

Mental state of adult patients, who since childhood had features of Asperger's syndrome (AS), was studied. We examined 107 patients (89 men and 18 women). At the moment of inclusion in the study, all the patients met criteria of ICD=10 for AS. This was confirmed by the examination of the patients with the help of ASDASQ and ASDI scales. Based on the results of psychopathological and psychological five variants of AS outcomes in the age of early adulthood were identified as follows: integrated, inhibitory, peculiar, border-line and hypernormative. At the moment of examination, psychosocial compensation was observed in 38% of patients, only 28% of patients were on treatment and 20% had a history of transitory psychotic episodes. The authors conclude that the results of the study suggest the relatively favorable prognosis of AS. The differential clinical evaluation of this group as well as implication of adequate psychosocial and psychotherapeutic methods in their treatment is needed.

This study used a theoretical model to determine whether an efficacy-enhancing teaching protocol was effective in improving immediate postoperative behaviors and selected short- and long-term health outcomes in women who underwent abdominal hysterectomies. The model used was the self-efficacy theory of Albert Bandura, PhD. One hundred eight patients in a 486-bed teaching hospital in the Midwest who underwent hysterectomies participated. The participation rate was 85%, and the attrition rate was 17% during the six-month study. The major finding was that participants in the efficacy-enhancing teaching group ambulated significantly longer than participants in the usual care group. This is an important finding because the most prevalent postoperative complications after hysterectomy are atelectasis, pneumonia, paralytic ileus, and deep vein thrombosis, and postoperative ambulation has been shown to decrease or prevent all of these complications. This finding could affect the overall health status of women undergoing hysterectomies.

The adverse pulmonary effects of asbestos are well accepted in scientific circles. However, the extrapulmonary consequences of asbestos exposure are not as clearly defined. In this review the potential for asbestos to produce diseases of the peritoneum, immune, gastrointestinal (GIT), and reproductive systems are explored as evidenced in published, peer-reviewed literature. Several hundred epidemiological, in vivo, and in vitro publications analyzing the extrapulmonary effects of asbestos were used as sources to arrive at the conclusions and to establish areas needing further study. In order to be considered, each study had to monitor extrapulmonary outcomes following exposure to asbestos. The literature supports a strong association between asbestos exposure and peritoneal neoplasms. Correlations between asbestos exposure and immune-related disease are less conclusive; nevertheless, it was concluded from the combined autoimmune studies that there is a possibility for a higher-than-expected risk of systemic autoimmune disease among asbestos-exposed populations. In general, the GIT effects of asbestos exposure appear to be minimal, with the most likely outcome being development of stomach cancer. However, IARC recently concluded the evidence to support asbestos-induced stomach cancer to be “limited.” The strongest evidence for reproductive disease due to asbestos is in regard to ovarian cancer. Unfortunately, effects on fertility and the developing fetus are under-studied. The possibility of other asbestos-induced health effects does exist. These include brain-related tumors, blood disorders due to the mutagenic and hemolytic properties of asbestos, and peritoneal fibrosis. It is clear from the literature that the adverse properties of asbestos are not confined to the pulmonary system. PMID:21534087

Background “Asthma-related quality of life” refers to the perceived impact that asthma has on the patient’s quality of life. Objective National Institutes of Health (NIH) institutes and other federal agencies convened an expert group to recommend standardized measures of the impact of asthma on quality of life for use in future asthma clinical research. Methods We reviewed published documentation regarding the development and psychometric evaluation; clinical research use since 2000; and extent to which the content of each existing quality of life instrument provides a unique, reliable, and valid assessment of the intended construct. We classified instruments as core (required in future studies), supplemental (used according to the study’s aims and standardized), or emerging (requiring validation and standardization). This work was discussed at an NIH-organized workshop convened in March 2010 and finalized in September 2011. Results Eleven instruments for adults and 6 for children were identified for review. None qualified as core instruments because they predominantly measured indicators of asthma control (symptoms and/or functional status); failed to provide a distinct, reliable score measuring all key dimensions of the intended construct; and/or lacked adequate psychometric data. Conclusions In the absence of existing instruments that meet the stated criteria, currently available instruments are classified as either supplemental or emerging. Research is strongly recommended to develop and evaluate instruments that provide a distinct, reliable measure of the patient’s perception of the impact of asthma on all of the key dimensions of quality of life, an important outcome that is not captured in other outcome measures.

OBJECTIVES: To describe the spectrum of cognitive outcomes of children with and without cerebral palsy (CP) after neonatal encephalopathy, evaluate the prognostic value of early developmental testing and report on school services and additional therapies. METHODS: The participants of this study are the school-aged survivors of the National Institute of Child Health and Human Development Neonatal Research Network randomized controlled trial of whole-body hypothermia. Children underwent neurologic examinations and neurodevelopmental and cognitive testing with the Bayley Scales of Infant Development–II at 18 to 22 months and the Wechsler intelligence scales and the Neuropsychological Assessment–Developmental Neuropsychological Assessment at 6 to 7 years. Parents were interviewed about functional status and receipt of school and support services. We explored predictors of cognitive outcome by using multiple regression models. RESULTS: Subnormal IQ scores were identified in more than a quarter of the children: 96% of survivors with CP had an IQ <70, 9% of children without CP had an IQ <70, and 31% had an IQ of 70 to 84. Children with a mental developmental index <70 at 18 months had, on average, an adjusted IQ at 6 to 7 years that was 42 points lower than that of those with a mental developmental index >84 (95% confidence interval, −49.3 to −35.0; P < .001). Twenty percent of children with normal IQ and 28% of those with IQ scores of 70 to 84 received special educational support services or were held back ≥1 grade level. CONCLUSIONS: Cognitive impairment remains an important concern for all children with neonatal encephalopathy. PMID:25713280

The purpose of the present investigation was to evaluate the contribution of age-at-insult and brain pathology on longitudinal outcome and recovery of pragmatic language in a sample of children and adolescents with traumatic brain injury (TBI). Children and adolescents with mild to severe TBI (n=112) were categorized according to timing of brain insult: (i) Middle Childhood (5-9 years; n=41); (ii) Late Childhood (10-11 years; n=39); and (iii) Adolescence (12-15 years; n=32) and group-matched for age, gender and socio-economic status (SES) to a typically developing (TD) control group (n=43). Participants underwent magnetic resonance imaging (MRI) including a susceptibility weighted imaging (SWI) sequence 2-8 weeks after injury and were assessed on measures of pragmatic language and behavioural functioning at 6- and 24-months after injury. Children and adolescents with TBI of all severity levels demonstrated impairments in these domains at 6-months injury before returning to age-expected levels at 2-years post-TBI. However, while adolescent TBI was associated with post-acute disruption to skills that preceded recovery to age-expected levels by 2-years post injury, the middle childhood TBI group demonstrated impairments at 6-months post-injury that were maintained at 2-year follow up. Reduced pragmatic communication was associated with frontal, temporal and corpus callosum lesions, as well as more frequent externalizing behaviour at 24-months post injury. Findings show that persisting pragmatic language impairment after pediatric TBI is related to younger age at brain insult, as well as microhemorrhagic pathology in brain regions that contribute to the anatomically distributed social brain network. Relationships between reduced pragmatic communication and more frequent externalizing behavior underscore the need for context-sensitive rehabilitation programs that aim to increase interpersonal effectiveness and reduce risk for maladaptive behavior trajectories into the

Outcomes are, simply put, why a surgeon comes to work each day. For decades, surgeons have insisted on a regular self-examination of outcomes to ensure the optimal treatment of our patients. Clinical research in pediatric surgery has largely subsisted on outcome analysis as it relates to the rudimentary end-result of an operation, utilizing variables such as mortality, operative time, specific complication rates, and hospital length of stay to name a few. Recently, outcomes research has become a more complex endeavor. This issue of Seminars in Pediatric Surgery addresses a wide array of these newfound complexities in contemporary outcomes research. The purpose of this review is to assist the pediatric surgeon in understanding the tools that are used in contemporary outcomes research and to be able to use this information to ask new questions of our patients and ourselves as we continue to strive for excellence in caring for sick infants and children.

This article describes how organizations devise strategic directions. The process of focused strategic or hoshin planning is introduced and reviewed. This model illustrates how a nursing department planned a focused strategic direction for outcomes evaluation. This discussion includes the dedication of resources, the focusing of research priorities and a summary of the outcomes evaluation program, and the method used for implementation of the priorities. Finally, benefits of both the focused planning process and the outcomes evaluation program are discussed.

Abstract Objective: Anecdotally, breastfeeding experiences differ between those who have previously nursed an infant and those who are primiparous. This analysis contrasted breastfeeding outcomes between primiparous women and those with previous experience spanning from maternity stay through 6 months postpartum. Study Design: A secondary analysis was conducted of data collected in a randomized, controlled trial with mothers and “well” newborns ≥34 weeks of gestation comparing two post–hospital discharge care models. Mothers completed an in-person interview during the postpartum stay and phone surveys at 2 weeks, 2 months, and 6 months where questionnaires related to breastfeeding were completed. All participants intended to breastfeed. Chi-squared and Wilcoxon rank sum tests were used to test for differences between parity groups. Breastfeeding duration by parity group was compared using a Kaplan–Meier plot and a logrank test. A Cox proportional hazards model was used to evaluate the relationship between breastfeeding duration and parity after adjusting for covariates. Results: Among 1,099 mothers available for analysis, 542 (49%) were primiparous. Multiparous mothers had a longer intended breastfeeding duration (median, 9 vs. 6 months; p<0.001). Following delivery, primiparous mothers had a longer median time to first breastfeeding attempt (119 vs. 96 minutes; p<0.001) and were more likely to have eight or fewer feeding attempts in the first 24 hours (33% vs. 44%; p<0.001)). More primiparous women reported early breastfeeding problems (35% vs. 20%; p<0.001) and mixed feeding at hospital discharge (39% vs. 23%; p<0.001) despite reporting less breastfeeding-associated pain during the first week (p=0.04). Multiparous women were more likely to breastfeed through 6 months (p<0.001). In a multivariable Cox model for breastfeeding duration, an interaction existed between intended breastfeeding duration and parity (p=0.006); among those intending to breastfeed

Outcome measurement is crucial to assuring high-quality patient services and improving the quality of services provided by prosthetists. This article summarizes recent evidence on the measurement properties of outcome measures, and updates previously published summaries of outcome instruments. The review focuses on measures of mobility, functional status, quality of life, and patient satisfaction, and includes both performance-based and patient-reported outcomes. Amputation-specific and general measures that are suitable for patients served by prosthetists are discussed. It is encouraging that responsiveness of measures is often reported, as this information is needed to improve clinical utility.

Synopsis This article provides an introduction to key aspects of outcomes research in pediatric rheumatology with focus on arthritis. Patient centered outcomes research addresses questions of interest to multiple stakeholders in order to guide the best health care decisions suited to a particular patient's circumstances and preferences. Discussion includes the importance of maintaining high quality longitudinal patient registries and use of valid clinical and patient reported outcome measures. Rapid, reliable translation of research on best practices into clinical care, as facilitated by quality improvement learning networks, leads to timely and meaningful improvement in patient outcomes.

As Medicaid expands in scope and influence, it is evolving toward being a “purchaser” of quality health care. This commentary discusses measurement and incentivization of clinical outcomes in Medicaid. Advantages and disadvantages of outcome versus process measures are discussed. Distinctions are drawn between the roles of Medicare and Medicaid, including the implications of the growth in Medicaid managed care. Medicaid's influence is particularly notable for obstetric, pediatric, newborn, and long-term care. We provide data on 3 Medicaid outcomes: potentially preventable hospital admissions, readmissions, and complications. The commentary concludes with suggestions for choosing and implementing outcome-oriented value-based purchasing initiatives in Medicaid. PMID:26945295

The purpose of this study is to evaluate the relationship between maternal and/or cord blood folate/homocysteine concentrations and adverse pregnancy outcomes. The study population included a random sample of singleton pregnant women in whom we measured total homocysteine and folic acid in maternal or cord blood at deliveries. A total of 227 pregnant women were enrolled. The concentration of folate in maternal blood tended to be significantly lower in pre-term birth than in full-term delivery group (median (95% CI), 14.4 (3.6-73) vs 25 (7.3-105.5) p < 0.01). The total homocysteine in maternal and cord blood was significantly higher in the pre-eclampsia than in the normotensive group (7.9 (1.7-28.2) vs 5.9 (1.8-14.6) μmol/ml, p < 0.05; and 5.8 (2.6-14.4) vs 4.2 (0.7-7.9) ng/ml, p < 0.05, respectively). Lower maternal serum folate concentration is associated with pre-term delivery and higher maternal plasma homocysteine concentration with pre-eclampsia.

Abstract Neurilemmoma commonly occurs from the fourth to sixth decades of life with an incidence of 3 to 10 per 100,000 people, and is rare in adolescence. This case report describes the clinical and radiographic features of 2 rare cases with intraspinal neurilemmoma of the cervical and thoracic spine. A 29-year-old man who experienced middle back pain with prominent right lower limb weakness, and an 11-year-old boy who suffered from sudden onset neck pain with left arm weakness and hand clawing for 2 weeks before admission to our department were included in this case report. Magnetic resonance imaging of both patients revealed an intraspinal mass causing spinal cord compression at the cervical and thoracic spine. The patients subsequently received urgent posterior spinal cord decompression and tumor resection surgery. The histopathology reports revealed neurilemmoma. The 2 patients recovered and resumed their normal lives within 1 year. Intraspinal neurilemmoma is rare but should be considered in the differential diagnosis of spinal cord compression. Advances in imaging techniques and surgical procedures have yielded substantially enhanced clinical outcomes in intraspinal neoplasm cases. Delicate preoperative study and surgical skill with rehabilitation and postoperative observation are critical. PMID:25654395

Both the initial evaluation and follow-up of patients with osteoarthritis require systematic evaluation of the indicators that provide information on the degree of involvement of the disease and allow its quantification. Reliable measures of disease progression help decision-making by clinicians and provide valid information on treatment response and the effectiveness of the distinct therapeutic interventions. The instruments recommended in research, as outcome measures in osteoarthritis, are pain evaluation, assessment of physical function, and self-reported global evaluation. In studies lasting more than 1 year, structural changes are evaluated through simple X-ray. Self-reported quality of life assessment and physician global assessment are also recommended as options. These indicators should be incorporated into routine clinical practice for adequate evaluation and correct follow-up of patients with osteoarthritis. The recommended pain evaluation method for use in clinical practice is the visual analog scale (VAS). The best instrument to evaluate physical function in patients with hip or knee osteoarthritis is the WOMAC scale (Western Ontario and McMaster Universities Osteoarthritis Index). For patient-reported global assessment in routine practice, the recommended scales are VAS or the SF-12 (12-item short-form health survey).

Social networks can profoundly affect human behavior, which is the primary force driving environmental change. However, empirical evidence linking microlevel social interactions to large-scale environmental outcomes has remained scarce. Here, we leverage comprehensive data on information-sharing networks among large-scale commercial tuna fishers to examine how social networks relate to shark bycatch, a global environmental issue. We demonstrate that the tendency for fishers to primarily share information within their ethnic group creates segregated networks that are strongly correlated with shark bycatch. However, some fishers share information across ethnic lines, and examinations of their bycatch rates show that network contacts are more strongly related to fishing behaviors than ethnicity. Our findings indicate that social networks are tied to actions that can directly impact marine ecosystems, and that biases toward within-group ties may impede the diffusion of sustainable behaviors. Importantly, our analysis suggests that enhanced communication channels across segregated fisher groups could have prevented the incidental catch of over 46,000 sharks between 2008 and 2012 in a single commercial fishery.

Diet and patterns of eating during pregnancy can affect perinatal outcomes through direct physiologic effects or by stressing the fetus in ways that permanently affect phenotype. Supplements are not a magic nutritional remedy, and evidence of profound benefit for most supplements remains inconclusive. However, research supports calcium supplements to decrease preeclampsia. Following a low glycemic, Mediterranean-type diet appears to improve ovulatory infertility, decrease preterm birth, and decrease the risk of gestational diabetes. Although women in the United States have adequate levels of most nutrients, subpopulations are low in vitamin D, folate, and iodine. Vitamin D has increasingly been shown to be important not only for bone health, but also for glucose regulation, immune function, and good uterine contractility in labor. To ensure adequate vitamin and micronutrient intake, especially of folate before conception, all reproductive age women should take a multivitamin daily. In pregnancy, health care providers need to assess women's diets, give them weight gain recommendations based on their body mass index measurement, and advise them to eat a Mediterranean diet rich in omega-3 fatty acids (ingested as low-mercury risk fatty fish or supplements), ingest adequate calcium, and achieve adequate vitamin D levels through sun exposure or supplements. Health care providers should continue to spend time on nutrition assessment and counseling.

Constipation, defined as delay or difficulty in defecation, present for 2 or more weeks, is a common problem encountered by both primary and specialty medical providers. There are no randomized controlled trials on the use of antegrade enemas in the pediatric population. Most published papers are based on the experience at a particular center. The aim of this article is to describe the pathophysiology of constipation, review the contribution of colonic manometry to the diagnosis of constipation, summarize the advancements in the management of constipation through the use of antegrade enemas, and study the outcomes of cecostomy at different centers. This study is a comprehensive literature review generated by computerized search of literature, supplemented by review of monographs and textbooks in pathology, gastroenterology, and surgery. Literature search was performed using the publications from 1997 to 2012. The search included publications of all types presenting or reviewing data on cecostomy. The antegrade continence enema is a therapeutic option for defecation disorders when maximal conventional therapy is not successful. Symptoms of defecation disorders in children with different underlying etiologies improve significantly after a cecostomy is created. In addition, there is a benefit on the patients' physical activity, healthcare utilization, and general well-being. Based on the review of published literature it seems that antegrade enemas are a successful therapeutic option in children with severe constipation and/or fecal incontinence. With the advent of cecostomy buttons, patient compliance and the overall cosmetic appearance have improved.

Accumulating evidence suggests an association between patient pretreatment expectations and numerous health outcomes. However, it remains unclear if and how expectations relate to outcomes after treatments in multidisciplinary pain programs. The present study aims at investigating the predictive association between expectations and clinical outcomes in a large database of chronic pain patients. In this observational cohort study, participants were 2272 patients treated in one of 3 university-affiliated multidisciplinary pain treatment centers. All patients received personalized care, including medical, psychological, and/or physical interventions. Patient expectations regarding pain relief and improvements in quality of life and functioning were measured before the first visit to the pain centers and served as predictor variables. Changes in pain intensity, depressive symptoms, pain interference, and tendency to catastrophize, as well as satisfaction with pain treatment and global impressions of change at 6-month follow-up, were considered as treatment outcomes. Structural equation modeling analyses showed significant positive relationships between expectations and most clinical outcomes, and this association was largely mediated by patients' global impressions of change. Similar patterns of relationships between variables were also observed in various subgroups of patients based on sex, age, pain duration, and pain classification. Such results emphasize the relevance of patient expectations as a determinant of outcomes in multimodal pain treatment programs. Furthermore, the results suggest that superior clinical outcomes are observed in individuals who expect high positive outcomes as a result of treatment.

In developing countries, 1/3 of infants are born weighing less than 2500 grams. A study conducted in Ethiopia among women consuming about 1600 kcal/day, those who were very physically active during pregnancy bore smaller babies, and gained less weight during pregnancy, than those who were not so active. Average birth weight was 3068 grams for the 1st group, 3270 grams for the less active. The active group of women gained an average of 6.5 kilograms, and the less active 9.2 kilograms. Women who did not engage in heavy work during pregnancy, although they were undernourished, apparently did not bear growth-retarded babies. Indirect evidence for the effect of physical activity on pregnancy outcome comes from studies conducted in Taiwan, and the Gambia. These studies, and others from Malawi, Burkina Faso, and Kenya have shown that women's energy expenditures vary greatly with the agricultural season. Daily housekeeping tasks, however, also consume a lot of women's energy. Technologies that allow women to reduce energy expenditure can have beneficial effects, if they do not simultaneously reduce their incomes. For instance, programs improving water or fuel availability, or reducing fuel needs, reduce women's energy expenditures. Food processing mills can help too if women have access to them, and are thus not in danger of being displaced from their jobs and losing necessary income. Examples of technology improving women's tasks are pedal drying machines for nice in Bangladesh, using a greater and pressing machine to prepare gari in Ghana; but growing thicker rice stalks in Indonesia displaced women workers and reduced income.

Spasticity is a frequent consequence of upper motor neuron lesion and is associated with a variety of symptoms such as pain, muscle stiffness and reflex patterns that interfere with activities of daily living, dexterity and gait. As therapy strategies in managing spasticity-associated problems have been evolving there is an increasing need for a practicable documentation system which describes spasticity and related symptoms on different levels in order to evaluate especially the level of functioning. In daily routine the single-case-design reflects a useful technique to evaluate the status in terms of technical, functional and individual goals for treatment. However, there is no single tool to measure the different types of changes due to treatment, therefore a variety of selecting tests, based on the functional changes expected from the selected treatment, is recommended. The sensitivity of the selected tests should match the range of expected improvements related to the specific treatment. Technical goals should be evaluated by validated spasticity rating scales. As changes in technical measures of spasticity such as muscle tone, muscle length, range of motion or repetitive voluntary movements may not correlate with clinical improvements, individual functional goals should be defined. Those functional goals should reflect the patients' and care-givers' individual perception of the actual problem. A treatment diary is a useful tool to document subjective perception of changes over time. Some practical issues are adressed below. Reliable outcome measures enable patients and doctors to select further treatment strategies and gives health care providers information on treatment expectations in return for their investments.

Purpose. To review the clinical outcome of patients with hypertensive uveitis. Methods. Retrospective review of uveitis patients with elevated intraocular pressure (IOP) > 25 mmHg and >1-year follow-up. Data are uveitis type, etiology, viral (VU) and nonviral uveitis (NVU), IOP, and medical and/or surgical treatment. Results. In 61 patients, IOP values are first 32.9 mmHg (SD: 9.0), highest 36.6 mmHg (SD: 9.9), 3 months after the first episode 19.54 mmHg (SD: 9.16), and end of follow-up 15.5 mmHg (SD: 6.24). Patients with VU (n = 25) were older (50.6 y/35.7 y, p = 0.014) and had more unilateral disease (100%/72.22% p = 0.004) than those with NVU (n = 36). Thirty patients (49.2%) had an elevated IOP before topical corticosteroid treatment. Patients with viral uveitis might have higher first elevated IOP (36.0/27.5 mmHg, p = 0,008) and maximal IOP (40.28/34.06 mmHg, p = 0.0148) but this was not significant when limited to the measurements before the use of topical corticosteroids (p = 0.260 and 0.160). Glaucoma occurred in 15 patients (24.59%) and was suspected in 11 (18.03%) without difference in viral and nonviral groups (p = 0.774). Conclusion. Patients with VU were older and had more unilateral hypertensive uveitis. Glaucoma frequently complicates hypertensive uveitis. Half of the patients had an elevated IOP before topical corticosteroid treatment. PMID:26504598

Many observational studies have consistently shown that high-flux hemodialysis has positive effects on the survival and morbidity of uremic patients when compared with low-flux hemodialysis. However, the HEMO study, a randomized trial designed to evaluate the effect of membrane permeability on patient survival, showed only an 8% non-statistically significant reduction of mortality, albeit a secondary analysis suggested an advantage for high-flux membranes in certain patient subgroups. The prospective, randomized Membrane Permeability Outcome (MPO) study investigated the impact of membrane permeability on survival in incident hemodialysis patients who had low albumin (≤4 g/dl) and normal albumin ( >4 g/dl) as separate randomization groups. Patients with serum albumin ≤4 g/dl had significantly better survival rates in the high-flux group compared with the low-flux group (p = 0.032). Moreover, a post-hoc secondary analysis showed that high-flux membranes may significantly improve survival in diabetic patients. No difference was found in patients with normal albumin levels. Considering the increasing number of dialysis patients with low serum albumin levels and with diabetes, the relevance of the MPO study led to the publication of a position statement by the European Renal Best Practice Advisory Board. This board strongly recommended that high-flux hemodialysis should be used for high-risk patients and, with a lower degree of evidence, even also for low-risk subjects due to the substantial reduction in β(2)-microglobulin levels observed in the high-flux group.

Rapid assessment of patients presenting with acute chest pain is essential, in order to distinguish between those who have a life-threatening condition, such as myocardial infarction or unstable angina, and the substantial proportion who do not have an acute coronary syndrome. It is thus of vital importance that reliable techniques are available to facilitate rapid risk stratification, as an aid to both clinical diagnosis and management strategy decisions. Assessments based on clinical findings, electrocardiographic monitoring, symptom-limited exercise testing, and biochemical marker measurements, used either singly or in various combinations, can fulfill this role. The present paper reviews some of the recent data that demonstrate the value of these techniques. Very few studies allow conclusions to be drawn about optimal treatment strategies in relation to groups stratified according to prognostic markers, and the question of whether intense medical treatment or early invasive intervention is most beneficial is one that clinical trials have yet to address adequately. In the recently completed Fragmin and Fast Revascularization during InStability in Coronary artery disease (FRISC II) study, comparisons were made of clinical outcomes achieved with early invasive versus noninvasive (i.e., medical) management strategies, and with short-term versus prolonged anticoagulation with dalteparin sodium (Fragmin), in patients with unstable coronary artery disease. All study participants underwent symptom-limited exercise testing and provided blood sample for measurements of biochemical markers; continuous electrocardiography monitoring and echocardiography were also performed in a high proportion of patients. Data from the FRISC II trial thus shed further light on the issue of risk stratification and its use to determine optimal treatment strategies.

Simulation of wear in total hip replacements has been recognised as an important factor in determining the likelihood of clinical success. However, accurate measurement of wear can be problematic with factors such as number and morphology of wear particles produced as well as ion release proving more important in the biological response to hip replacements than wear volume or wear rate alone. In this study, hard-on-hard (CoCr alloy, AgCrN coating) and hard-on-soft (CoCr alloy and CrN coating on vitamin E blended highly cross-linked polyethylene) bearing combinations were tested in an orbital hip simulator under standard and some adverse conditions. Gravimetric wear rates were determined for all bearings, with cobalt and where applicable, silver release determined throughout testing. Isolation of wear particles from the lubricating fluid was used to determine the influence of different bearing combinations and wear conditions on particle morphology. It was found that cobalt and silver could be measured in the lubricating fluid even when volumetric wear was not detectable. In hard-on-hard bearings, Pearson's correlation of 0.98 was established between metal release into the lubricating fluid and wear volume. In hard-on-soft bearings, coating the head did not influence the polyethylene wear rates measured under standard conditions but did influence the cobalt release; the diameter influenced both polyethylene wear and cobalt release, and the introduction of adverse testing generated smaller polyethylene particles. While hip simulators can be useful to assess the wear performance of a new material or design, measurement of other outcomes may yield greater insight into the clinical behaviour of the bearings in vivo.

Maternal nutritional status during pregnancy will affect the outcomes for the mother and the baby. Many analyses of the relationship between diet and outcome are often based on a single or a few food items or nutrients. However, foods are not consumed in isolation and dietary patterns can be used to assess the whole diet consumed. The use of dietary pattern analysis to understand nutritional intake and pregnancy outcome is becoming more and more popular. Many published studies have showed the association between maternal dietary patterns and pregnancy outcome. This review examined articles about the relationship between maternal dietary patterns and pregnancy outcome. As a modifiable factor, dietary patterns may be more applicable to clinical and pregnant health interventions. PMID:27338455

Clinical outcome prediction, as strong implications for health service delivery of clinical treatment processes (CTPs), is important for both patients and healthcare providers. Prior studies typically use a priori knowledge, such as demographics or patient physical factors, to estimate clinical outcomes at early stages of CTPs (e.g., admission). They lack the ability to deal with temporal evolution of CTPs. In addition, most of the existing studies employ data mining or machine learning methods to generate a prediction model for a specific type of clinical outcome, however, a mathematical model that predicts multiple clinical outcomes simultaneously, has not yet been established. In this study, a hybrid approach is proposed to provide a continuous predictive monitoring service on multiple clinical outcomes. More specifically, a probabilistic topic model is applied to discover underlying treatment patterns of CTPs from electronic medical records. Then, the learned treatment patterns, as low-dimensional features of CTPs, are exploited for clinical outcome prediction across various stages of CTPs based on multi-label classification. The proposal is evaluated to predict three typical classes of clinical outcomes, i.e., length of stay, readmission time, and the type of discharge, using 3492 pieces of patients' medical records of the unstable angina CTP, extracted from a Chinese hospital. The stable model was characterized by 84.9% accuracy and 6.4% hamming-loss with 3 latent treatment patterns discovered from data, which outperforms the benchmark multi-label classification algorithms for clinical outcome prediction. Our study indicates the proposed approach can potentially improve the quality of clinical outcome prediction, and assist physicians to understand the patient conditions, treatment inventions, and clinical outcomes in an integrated view.

In congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, affected girls are born with ambiguous genitalia due to increased secretion of androgens in utero by the defective adrenal gland. Even though it is generally accepted that there are differences between male and female brain development, determining factors have been difficult to identify. Girls with CAH have frequently been studied to evaluate the impact of prenatal androgen exposure on psychological, psychosocial, and psychosexual development, and impairments in various areas have been identified. However, there is no comprehensive study available regarding the outcome of this chronic disorder in adult life. We studied the quality of life in women with CAH, with particular emphasis on how they cope with genital malformations, genital operations, and chronic disease as well as lifelong medication. The patients filled out questionnaires covering their physical state, psychological well-being, social relationships, and functional capacity, as well as questionnaires on psychosexual identification and psychosocial integration. The results were evaluated using a computerized statistical program for social studies. Out of a total of 94 patients above 18 years of age, 45 agreed to participate and were compared to 46 healthy, age-matched controls. Age at diagnosis was 2. 31 +/- 1.55 years and 38% suffered from the simple-virilizing, 45% from the salt-wasting, and 17.0% from the late-onset form of CAH. About one-third of patients had Prader stage 3 or 4 genital virilization. While the overall quality of life did not differ significantly, CAH patients were more often single (47.8% vs. 66.7%) and fewer of them had children (22.2% vs. 38.6%) compared to controls. Significant impairments were found in regard to body image and attitudes toward sexuality, but there was no increased homosexual preference. The women were successful in adjusting to illness and receiving social support. It is speculated that

Health systems around the world are implementing integrated care strategies to improve quality, reduce or maintain costs, and improve the patient experience. Yet few practical tools exist to aid leaders and managers in building the prerequisites to integrated care, namely a shared vision, clear roles and responsibilities, and a common understanding of how the vision will be realized. Outcome mapping may facilitate stakeholder alignment on the vision, roles, and processes of integrated care delivery via participative and focused dialogue among diverse stakeholders on desired outcomes and enabling actions. In this paper, we describe an outcome-mapping exercise we conducted at a Local Health Integration Network in Ontario, Canada, using consensus development conferences. Our preliminary findings suggest that outcome mapping may help stakeholders make sense of a complex system and foster collaborative capital, a resource that can support information sharing, trust, and coordinated change toward integration across organizational and professional boundaries. Drawing from the theoretical perspectives of complex adaptive systems and collaborative capital, we also outline recommendations for future outcome-mapping exercises. In particular, we emphasize the potential for outcome mapping to be used as a tool not only for identifying and linking strategic outcomes and actions, but also for studying the boundaries, gaps, and ties that characterize social networks across the continuum of care.

Long term outcomes after liver transplantation are major determinants of quality of life and of the value of this heroic treatment. As short term outcomes are excellent, our community is turning to take a harder look at long term outcomes. The purpose of this paper is to review these outcomes, and highlight proposed treatments, as well as pressing topics needing to be studied. A systemic review of the English literature was carried in PubMed, covering all papers addressing long term outcomes in pediatric liver transplant from 2000-2013. Late outcomes after pediatric liver transplant affect the liver graft in the form of chronic liver dysfunction. The causes include rejection particularly humoral rejection, but also de novo autoimmune hepatitis, and recurrent disease. The metabolic syndrome is a major factor in long term cardiovascular complication risk. Secondary infections, kidney dysfunction and malignancy remain a reality of those patients. There is growing evidence of late cognitive and executive function delays affecting daily life productivity as well as likely adherence. Finally, despite a good health status, quality of life measures are comparable to those of children with chronic diseases. Long term outcomes are the new frontier in pediatric liver transplantation. Much is needed to improve graft survival, but also to avoid systemic morbidities from long term immunosuppression. Quality of life is a new inclusive measure that will require interventions and innovative approaches respectful not only on the patients but also of their social circle. PMID:24511516

Background A National Spina Bifida Patient Registry (NSBPR) was begun in 2009 to help understand the natural history of spina bifida (SB) and the effects of treatments provided by SB clinics. We used the NSBPR to explore the relationship of sociodemographic characteristics with SB outcomes. Methods Using NSBPR data collected in 2009 to 2012, we examined the unadjusted association between demographic characteristics and 4 SB outcomes: bowel continence, bladder continence, mobility, and presence of pressure sores. We then developed multivariable logistic models to explore these relationships while controlling for SB clinic, SB type, and level of lesion. Results Data were available on 2054 patients <22 years of age from 10 SB clinics. In the multivariable models, older age groups were more likely to have continence and pressure sores and less likely to be community ambulatory. Males and patients without private insurance were less likely to be continent and community ambulatory. Non-Hispanic blacks were less likely to be continent. Level of lesion was associated with all outcomes; SB type was associated with all but pressure sores; and all outcomes except community ambulation showed significant variation across clinic sites. Conclusions Sociodemographic attributes are associated with SB outcomes. In particular, males, non-Hispanic blacks, and patients without private insurance have less favorable outcomes, and age has an impact as well. These characteristics need to be considered by clinicians who care for this patient population and factored into case-mix adjustment when evaluating variation in clinical and functional outcomes among different SB clinics.

Intensivists, surgeons, neurologists, and others involved in pediatric intensive care units (PICUs) have an important investment in both short-and long-term outcomes of children and adolescents with head injury who are treated under their care. Outcomes are most often documented by either single- or multiple-item rating scales and are implemented both during and after hospital care. For this review, the authors have organized the content of rating scales into 6 general classes: (1) mortality prediction, (2) severity, (3) global recovery, (4) activity restrictions, (5) secondary adverse conditions, and (6) limitations in participation, quality of life, and health status. Rating scales that describe the outcomes of children and adolescents after head injury are used to monitor medical and functional recovery, guide clinical management, drive quality assurance initiatives, and conduct clinical research. The authors restrict their selective review to rating scales that describe child outcomes (vs family) and that have been reported and applied in the outcome literature. Although head injury is a major cause of mortality and short- and long-term morbidity in children and adolescents, there is no consensus on which rating scales are optimal for hospital care or community follow-up. Major considerations for clinical use are feasibility, type of outcome information needed, content breadth across multiple ages and levels of recovery, and utility in determining the short-term impact of PICU care on long-term outcome.

The effective evaluation and management of orthopaedic conditions including shoulder disorders relies upon understanding the level of disability created by the disease process. Validated outcome measures are critical to the evaluation process. Traditionally, outcome measures have been physician derived objective evaluations including range of motion and radiologic evaluations. However, these measures can marginalize a patient’s perception of their disability or outcome. As a result of these limitations, patient self-reported outcomes measures have become popular over the last quarter century and are currently primary tools to evaluate outcomes of treatment. Patient reported outcomes measures can be general health related quality of life measures, health utility measures, region specific health related quality of life measures or condition specific measures. Several patients self-reported outcomes measures have been developed and validated for evaluating patients with shoulder disorders. Computer adaptive testing will likely play an important role in the arsenal of measures used to evaluate shoulder patients in the future. The purpose of this article is to review the general health related quality-of-life measures as well as the joint-specific and condition specific measures utilized in evaluating patients with shoulder conditions. Advances in computer adaptive testing as it relates to assessing dysfunction in shoulder conditions will also be reviewed. PMID:25405091

Introduction The differential outcomes of laparoscopic adrenalectomy are not well described. Therefore, we evaluated these outcomes in the 3 groups most often seen clinically: bilateral adrenalectomy for Cushing's disease (group 1), pheochromocytoma (group 2) and unilateral adrenalectomy for non-pheochromocytoma (group 3). Methods We reviewed a longitudinal database of 72 consecutive cases of laparoscopic adrenalectomy carried out between 1997 and 2001 at the Centre for Minimally Invasive Surgery, University of Toronto. Results Patients in group 1 tended to be older (median 49 yr) and heavier (median 87 kg). They had a longer operating time (median 255 min), more postoperative complications (15%) and a longer median postoperative stay (4 d). Patients in group 2 had intermediate outcomes: a median operating time of 198 minutes, complication rate of 8.3% and a median postoperative hospital stay of 3 days. However, they had more intraoperative blood loss (median 150 mL). Group 3 patients had the best outcomes with the shortest median operating time (125 min), least blood loss (median 50 mL), fewer complications (6%) and shortest hospital stay (median 2 d). Conclusions Although the outcomes of laparoscopic adrenalectomy are uniformly good, on the basis of the underlying pathologic characteristics, patients can be divided into groups that have different expected outcomes. Patients requiring a unilateral adrenalectomy except for pheochromocytoma have the best recorded outcomes. Surgeons transferring to laparoscopic adrenalectomy would benefit from selecting patients in this group during their learning curve. PMID:14577705

Women have been increasingly delaying the start of motherhood in recent decades. The same trend is seen also for men. The influence of maternal age on fertility, chromosomal anomalies, pregnancy complications, and impaired perinatal and post-natal outcome of offspring, has been thoroughly investigated, and these aspects are clinically applied during fertility and pregestational counseling. Male aging and reproductive outcome has gained relatively less attention. The purpose of this review is to evaluate updated and relevant literature on the effect of paternal age on reproductive outcome. PMID:22157982
Clinical trials are large and expensive and could require exceedingly long-term follow-up for subjects to reach clinically meaningful end points. To combat these methodologic issues, researchers sometimes use biomarkers as surrogate end points. A biomarker is an objectively measured characteristic that is indicative of some underlying phenomenon or process, while a surrogate is a biomarker that "takes the place" of a clinically meaningful outcome, usually earlier in the disease process. This paper reviews the history, strengths, and weaknesses of surrogate outcome use in clinical research and then discusses potential surrogate outcomes in nephrology research.

In this article we review the literature on financial literacy, financial education, and consumer financial outcomes. We consider how financial literacy is measured in the current literature, and examine how well the existing literature addresses whether financial education improves financial literacy or personal financial outcomes. We discuss the extent to which a competitive market provides incentives for firms to educate consumers or offer products that facilitate informed choice. We review the literature on alternative policies to improve financial outcomes, and compare the evidence to evidence on the efficacy and cost of financial education. Finally, we discuss directions for future research.

Predicting functional outcome in stroke is challenging to most clinicians, partly because of the complexity of the condition and also because of the lack of validated prognostic models. The strongest predictors of functional outcome are age and motor function at stroke onset. There is a growing literature on predicting recovery of upper limb after stroke; however, literature on prediction of language recovery remains sparse. This review covers the current status of predicting functional outcome after stroke focusing on recovery of activities of daily living, ambulation, upper limb use, and aphasia. Use of clinical factors, imaging, and neurophysiological measures are discussed.

In the current health care market, there is a sharp awareness by both consumers and managed care providers that hospitals are only as good as the outcomes they can produce. Collaboration among disciplines that provide services, in this case treatment for stroke has enhanced patient outcomes. The synergy that has developed among those involved has thus far created a win-win situation. The key to successful outcomes is to have all those involved possessing a clear picture of their role, accepting it, and taking ownership of it.

Whereas a large literature has shown the importance of early life health for adult socioeconomic outcomes, there is little evidence on the importance of adolescent health. We contribute to the literature by studying the impact of adolescent health status on adult labor market outcomes using a unique and large-scale dataset covering almost the entire population of Swedish males. We show that most types of major conditions have long-run effects on future outcomes, and that the strongest effects result from mental conditions. Including sibling fixed effects or twin pair fixed effects reduces the magnitudes of the estimates, but they remain substantial.

Thermography; Ground Penetrating Radar; low-frequency Geophysical Techniques; ground based SAR and optical cameras for the assessment of the dynamical behaviour of the infrastructure. A great effort has been devoted to "transfer" these novel and state-of art technologies from the laboratory experience to actual on field applications by adapting/improving them and developing prototypes for the specific application domain of the monitoring of transport and critical infrastructures. Sensor synergy, data cross correlation and novel concepts of information fusion have permitted to carry out a multi-method, multi-resolution and multi-scale electromagnetic detection and monitoring of the infrastructure, including surface and subsurface aspects. The project has allowed to develop an ICT architecture based on web sensors and serviceoriented- technologies that comply with specific end-user requirements, including interoperability, economical convenience, exportability, efficiency and reliability. The efforts have focussed mainly to the creation of web based interfaces able to control "not standard" sensors, as the ones proposed in the project, and to the standardization necessary to have a full interoperability and modularity of the monitoring system. In addition, the system is able to provide a more easily accessible and transparent scheme for use by different end-users and to integrate the monitoring results and images with other kind of information such as GIS layer and historical datasets relating to the site. The ISTIMES system has been evaluated at two test sites and two test beds. At the two test sites of Montagnole rock-fall station (Chambery, France) and Hydrogeosite Laboratory (Potenza, Italy), the attention was posed to a thorough analysis of the performances of the in situ sensing techniques, by investigating, with good outcomes, also the possibility to correlate and have a synergy from the different sensors. In particular, it is worth noting that the experiment realized at

Background Use of supplemental registered nurses (SRNs) is common practice among U.S. hospitals to fill gaps in nurse staffing. Objective To examine the relationship between use of SRNs and patient outcomes. Methods Multilevel modeling was performed to analyze hospital administrative data from 19 hospital units in a large tertiary medical center for the years 2003–2006. Patient outcomes included in-hospital mortality, medication errors, falls, pressure ulcers, and patient satisfaction with nurses. Results SRN use ranged from 0–30.4% of total RN hours per unit quarter. Among 188 of the 304 unit quarters in which SRNs were used, the average SRN use was 9.8% in non-ICUs and 6.4% in ICUs. All observed effects of SRN use on patient outcomes were non-significant. Conclusions SRN use was substantial and varied widely by unit. No evidence was found that links SRN use to either adverse or positive patient outcomes. PMID:23151931

Procedural quality is an important aspect of crime victims' experiences in criminal proceedings and consists of different dimensions. Two of these dimensions are procedural justice (voice) and interpersonal justice (respectful treatment). Social psychological research has suggested that both voice and respectful treatment are moderated by the impact of outcomes of justice procedures on individuals' reactions. To add to this research, we extend this assertion to the criminal justice context, examining the interaction between the assessment of procedural quality and outcome favorability with victim's trust in the legal system and self-esteem. Hierarchical regression analyses reveal that voice, respectful treatment and outcome favorability are predictive of trust in the legal system and self-esteem. Further investigation reveals that being treated with respect is only related to trust in the legal system when outcome favorability is high.

The healthcare environment has been impacted tremendously by higher patient acuity, cost-cutting measures, an increase in litigation, and increased expectations by an educated generation of healthcare consumers. This has led to the need to continually measure, assess, and improve quality. These activities must consider not only patient clinical outcomes, but also customer service ratings and financial outcomes. Quality improvement requires a collaborative approach to succeed, and the need to build a cohesive and effective multidisciplinary team is critical for positive outcomes. Strategies to build a culture of teamwork include incorporating total quality management principles into every level of the organization, seeking participation from every discipline and level of the organization, and recognizing employees for their efforts. Infusion nurses have an excellent opportunity to contribute their expertise to any multidisciplinary team that impacts the outcomes of infusion patients. In addition, team-building and quality improvement may prove to be excellent career moves for infusion nurses looking to further specialize their practice.

Countries across the globe are experiencing nursing shortages. In hospitals, supportive practice environments have positive effects on both nurse and patient outcomes. However, these relationships have been established primarily in the US. International studies of the effects of nurse staffing levels and the practice environment on nurse outcomes and the quality of care mirror the findings from the US, thus raising these issues to the international level. The solutions that have been successful in the US for improving practice environment and patient outcomes are solutions that should be successful in any country, thus putting them on a global scale. The Magnet hospital program is one model that has been shown to improve nurse and patient outcomes and is one solution to the shortage of hospital nurses. PMID:18218265

Background and Objectives The relationship between patients’ baseline expectations regarding treatment outcome and actual outcomes has not been widely studied within the field of substance use disorders. We hypothesized that outcome expectations would be unrelated to outcomes in a study investigating Motivational Enhancement Therapy delivered in English (MET-E) consistent with our earlier work, and conducted exploratory analyses in a separate study that investigated the same treatment delivered in Spanish (MET-S). Methods These secondary analyses compared patient outcome expectations and substance use treatment outcomes in two large, multisite randomized controlled clinical trials that evaluated three sessions of MET-E or MET-S. The MET-E sample included 461 participants and the MET-S sample included 405 participants. Outcome expectations were measured by a single item regarding expectations about abstinence prior to initiating treatment. Results Outcome expectations were strongly associated with most substance use outcomes in the MET-S trial (but not in MET-E), even after controlling for severity of substance use at baseline. In MET-S, those who indicated that they were ‘unsure’ that they would achieve abstinence during treatment submitted a greater percentage of drug-positive urine toxicology screens during the treatment period than those who were ‘sure’ they would achieve abstinence (F = 18.83, p <.001). Discussion and Conclusions Patients’ outcome expectations regarding the likelihood of abstinence may be an important predictor of drug use treatment outcomes among Spanish-speakers, but not necessarily for English-speakers. Scientific Significance Individual differences and cultural factors may play a role in the association between outcome expectations and treatment outcomes. PMID:26541501

Operative treatment of displaced patella fractures with tension band fixation remains the gold standard, but is associated with a significant rate of complications and symptomatic implants. Despite the evolution of tension band fixation to include cannulated screws, surprisingly little other development has been made to improve overall patient outcomes. In this article, we present the techniques and outcomes of patella plating for displaced patella fractures and patella nonunions.

Background and Purpose Infections are common following stroke and associated with worse outcome. Clinical trials evaluating the benefit of prophylactic antibiotics have produced mixed results. This study explores the possibility that antibiotics of different classes may differentially affect stroke outcome. Methods Lewis rats were subjected to transient cerebral ischemia (2 hrs) and survived for 1 month. The day after stroke they were randomized to therapy with ceftiofur (a β-lactam antibiotic), enrofloxacin (a fluoroquinolone antibiotic) or vehicle (as controls) and underwent the equivalent of 7 days of treatment. Behavioral tests were performed weekly until sacrifice. In a subset of animals, histology was done. Results There were no differences in outcomes at 24 hours or 1 week after stroke among the different groups. At 1 month after stroke, however, performance on the rotarod was worse in enrofloxacin treated animals when compared to control animals. Conclusions Independent of infection, the antibiotic enrofloxacin was associated with worse stroke outcome. These data echo the clinical observations to date and suggest that the secondary effects of antibiotics on stroke outcome should be considered when treating infection in subjects with stroke. The mechanism by which this antibiotic affects outcome needs to be elucidated. PMID:26138122

Infants born at extreme preterm gestation are at risk for both death and disability. Although rates of survival have improved for this population, and some evidence suggests a trend toward decreased neuromotor impairment over the past decades, a significant improvement in overall early neurodevelopmental outcome has not yet been realized. This review will examine the rates and types of neurodevelopmental impairment seen after extremely preterm birth, including neurosensory, motor, cognitive, and behavioral outcomes. We focus on early outcomes in the first 18-36 months of life, as the majority of large neonatal studies examining neurodevelopmental outcomes stop at this age. However, this early age is clearly just a first glimpse into lifetime outcomes; the neurodevelopmental effects of extreme prematurity may last through school age, adolescence, and beyond. Importantly, prematurity appears to be an independent risk factor for adverse development, but this population demonstrates considerable variability in the types and severity of impairments. Understanding both the nature and prevalence of neurodevelopmental impairment among extremely preterm infants is important because it can lead to targeted interventions that in turn may lead to improved outcomes.

The Adverse Outcome Pathway (AOP) framework provides a template that facilitates understanding of complex biological systems and the pathways of toxicity that result in adverse outcomes (AOs). The AOP starts with an molecular initiating event (MIE) in which a chemical interacts with a biological target(s), followed by a sequential series of KEs, which are cellular, anatomical, and/or functional changes in biological processes, that ultimately result in an AO manifest in individual organisms and populations. It has been developed as a tool for a knowledge-based safety assessment that relies on understanding mechanisms of toxicity, rather than simply observing its adverse outcome. A large number of cellular and molecular processes are known to be crucial to proper development and function of the central (CNS) and peripheral nervous systems (PNS). However, there are relatively few examples of well-documented pathways that include causally linked MIEs and KEs that result in adverse outcomes in the CNS or PNS. As a first step in applying the AOP framework to adverse health outcomes associated with exposure to exogenous neurotoxic substances, the EU Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM) organized a workshop (March 2013, Ispra, Italy) to identify potential AOPs relevant to neurotoxic and developmental neurotoxic outcomes. Although the AOPs outlined during the workshop are not fully described, they could serve as a basis for further, more detailed AOP development and evaluation that could be useful to support human health risk assessment in a variety of ways.

Tumours are known to be heterogeneous, yet typical treatment plans consider them as a single unit. This may influence treatment outcomes. However, treatment cannot be customised to intra-tumour variation without a method to establish outcomes at an intra-tumour scale. This work proposes a method to both assess and measure outcomes locally within tumours. Methods: Four patients were scanned at two post-surgery time points using contrast enhanced MRI and 3,4-dihydroxy-6-[18F]-fluoro-L-phenylalanine (18F-DOPA) PET. The shell of active tumour tissue is divided into a set of small subregions at both time points. Local outcome is measured from changes in subregion volume over time. The utility of the proposed approach is evaluated by measuring the correlation between PET uptake and documented growth. Correlation with overall survival time was also examined. Results: Local outcomes were heterogeneous and evidence of a positive correlation between local 18F-DOPA uptake and local progression was observed. Conclusions: Given that intra-tumour outcomes are heterogeneous the consistently positive correlation between FDOPA uptake and progression, local analysis of tumours could prove useful for treatment planning.

Adverse pregnancy outcomes significantly contribute to morbidity and mortality for mother and child, with lifelong health consequences for both. The innate and adaptive immune system must be regulated to insure survival of the feta allograft, and the complement system is no exception. An intact complement system optimizes placental development and function and is essential to maintain host defense and fetal survival. Complement regulation is apparent at the placental interface from early pregnancy with some degree of complement activation occurring normally throughout gestation. However, a number of pregnancy complications including early pregnancy loss, fetal growth restriction, hypertensive disorders of pregnancy and preterm birth are associated with excessive or misdirected complement activation, and are more frequent in women with inherited or acquired complement system disorders or complement gene mutations. Clinical studies employing complement biomarkers in plasma and urine implicate dysregulated complement activation in components of each of the adverse pregnancy outcomes. In addition, mechanistic studies in rat and mouse models of adverse pregnancy outcomes address the complement pathways or activation products of importance and allow critical analysis of the pathophysiology. Targeted complement therapeutics are already in use to control adverse pregnancy outcomes in select situations. A clearer understanding of the role of the complement system in both normal pregnancy and complicated or failed pregnancy will allow a rational approach to future therapeutic strategies for manipulating complement with the goal of mitigating adverse pregnancy outcomes, preserving host defense, and improving long term outcomes for both mother and child.

Glomerulonephritis (GN) is a major cause of chronic renal failure (CRF). To evaluate the trends and outcome with modern improved treatment strategies, we retrospectively reviewed the clinical records of 120 patients with biopsy proven primary GN at our center from January 1990 to June 2001. All the biopsy specimens were subjected to light, electron and immunofluorescent microscopy. The recorded clinical parameters included the presenting symptoms, blood pressure readings, complete blood count, urinalysis, 24-hr urinary protein excretion, creatinine clearance besides rendered therapy and the outcome. Focal segmental glomerulosclerosis was the most common GN and accounted for 56 (47.6%) cases. The frequency of other GN cases in our study included IgA GN in 21 (17.5%) patients, membranous GN in 20 (16.7%), minimal change disease (MCD) in 13 (10.8%), membranoproliferative GN in 4 (3.3%), post infection in 4 (3.3%) and rapidly progressive glomerulonephritis (RPGN) in 2 (1.7%). The type of nephropathy had great influence on outcome and response to therapy. The deterioration of patients with FSGS was the fastest of the glomerulopathies, and nine (16.1%) patients developed end-stage renal failure (ESRD). MCD and post infection GN had the best outcome. Corticosteroids alone along with supportive medication conferred good results in MCD, while combined therapies of mycophenolate mofetil (MMF) and/or cyclophosphamide with corticosteroids provided better outcomes in the rest of the GN. RPGN responded well to the cyclophosphamide and the patients did not develop ESRD. Hyperuricemia, high serum creatinine and hypertension predicted worse outcomes. The control of blood pressure and glucose, and treatment of hyperuricemia and hypoalbuminemia had salutary effect on the outcome. We conclude that due to the better delivered care the outcome of primary GN has improved over the years. However, FSGS is still the most frequently encountered primary GN and has the worst outcome.

Severe shock is a life-threatening condition with very high short-term mortality. Whether the long-term outcomes among survivors of severe shock are similar to long-term outcomes of other critical illness survivors is unknown. We therefore sought to assess long-term survival and functional outcomes among 90-day survivors of severe shock and determine whether clinical predictors were associated with outcomes. Seventy-six patients who were alive 90 days after severe shock (received ≥1 μg/kg per minute of norepinephrine equivalent) were eligible for the study. We measured 3-year survival and long-term functional outcomes using the Medical Outcomes Study 36-Item Short-Form Health Survey, the EuroQOL 5-D-3L, the Hospital Anxiety and Depression Scale, the Impact of Event Scale-Revised, and an employment instrument. We also assessed the relationship between in-hospital predictors and long-term outcomes. The mean long-term survival was 5.1 years; 82% (62 of 76) of patients survived, of whom 49 were eligible for follow-up. Patients who died were older than patients who survived. Thirty-six patients completed a telephone interview a mean of 5 years after hospital admission. The patients' Physical Functioning scores were below U.S. population norms (P < 0.001), whereas mental health scores were similar to population norms. Nineteen percent of the patients had symptoms of depression, 39% had symptoms of anxiety, and 8% had symptoms of posttraumatic stress disorder. Thirty-six percent were disabled, and 17% were working full-time. Early survivors of severe shock had a high 3-year survival rate. Patients' long-term physical and psychological outcomes were similar to those reported for cohorts of less severely ill intensive care unit survivors. Anxiety and depression were relatively common, but only a few patients had symptoms of posttraumatic stress disorder. This study supports the observation that acute illness severity does not determine long-term outcomes. Even extremely

In outcome-selective Pavlovian-to-instrumental transfer (PIT), stimuli that are predictive of specific outcomes prime instrumental responses that are associated with these outcomes. Previous human studies yielded mixed evidence in respect to whether the PIT effect is affected by a posttraining devaluation of an outcome, with the PIT effect being preserved after a devaluation of a primary reinforcer (food, drugs) but not following the devaluation of a secondary reinforcer (money). The present research examined whether outcome-selective transfer is eliminated when the devaluation of a primary (liquid) reinforcer is strong and aversive. Experiment 1 confirmed these expectations following a devaluation with bad tasting Tween 20. However, outcome-selective transfer was still observed when the earned (devalued) outcome was not consumed immediately after each test (Experiment 2). These results suggest that the capacity of a Pavlovian cue to motivate a specific response is affected by the incentive value of the shared outcome only when the devaluation yields an aversive outcome that is consumed immediately.

A century ago the Boston surgeon Earnest A. Codman described in detail the requirements for monitoring quality of care and emphasized the importance of outcomes in evaluating care. At the time the medical societies were disconcerted by his ideas, which were perceived as revolutionary. After several decade of focusing on the structures and processes of care we are now witnessing a renaissance of measuring outcomes. This paper emphasizes the need for outcomes measurement monitor quality of care. The introduction of diagnosis-related groups in Germany is the most recent development that underlines the importance of outcomes measurement and benchmarking.

Study Design A broad narrative review. Objectives Outcome assessment in spinal disorders is imperative to help monitor the safety and efficacy of the treatment in an effort to change the clinical practice and improve patient outcomes. The following article, part two of a two-part series, discusses the various outcome tools and instruments utilized to address spinal disorders and their management. Methods A thorough review of the peer-reviewed literature was performed, irrespective of language, addressing outcome research, instruments and tools, and applications. Results Numerous articles addressing the development and implementation of health-related quality-of-life, neck and low back pain, overall pain, spinal deformity, and other condition-specific outcome instruments have been reported. Their applications in the context of the clinical trial studies, the economic analyses, and overall evidence-based orthopedics have been noted. Additional issues regarding the problems and potential sources of bias utilizing outcomes scales and the concept of minimally clinically important difference were discussed. Conclusion Continuing research needs to assess the outcome instruments and tools used in the clinical outcome assessment for spinal disorders. Understanding the fundamental principles in spinal outcome assessment may also advance the field of "personalized spine care."

Background Subjective well-being as a predictor for later behavior and health has highlighted its relationship to health, work performance, and social relationships. However, the majority of such studies neglect the developmental nature of well-being in contributing to important changes across the transition to adulthood. Methods To examine the potential role of subjective well-being as a long-term predictor of critical life outcomes, we examined indicators of positive and negative affect at age 14 as a predictor of relationship, adjustment, self worth, and career outcomes a decade later at ages 23 to 25, controlling for family income and gender. We utilized multi-informant methods including reports from the target participant, close friends, and romantic partners in a demographically diverse community sample of 184 participants. Results Early adolescent positive affect predicted less relationship problems (less self-reported and partner-reported conflict, greater friendship attachment as rated by close peers), healthy adjustment to adulthood (lower levels of depression, anxiety, and loneliness). It also predicted positive work functioning (higher levels of career satisfaction and job competence) and increased self-worth. Negative affect did not significantly predict any of these important life outcomes. In addition to predicting desirable mean levels of later outcomes, early positive affect predicted beneficial changes across time in many outcomes. Conclusions The findings extend early research on the beneficial outcomes of subjective well-being by having an earlier assessment of well-being, including informant reports in measuring a large variety of outcome variables, and by extending the findings to a lower socioeconomic group of a diverse and younger sample.

The days of surprise about actual election outcomes in the big data world are likely to be fewer in the years ahead, at least to those who may have access to such data. In this paper we highlight the potential for forecasting the Unites States presidential election outcomes at the state and county levels based solely on the data about viewership of television programs. A key consideration for relevance is that given the infrequent nature of elections, such models are useful only if they can be trained using recent data on viewership. However, the target variable (election outcome) is usually not known until the election is over. Related to this, we show here that such models may be trained with the television viewership data in the "safe" states (the ones where the outcome can be assumed even in the days preceding elections) to potentially forecast the outcomes in the swing states. In addition to their potential to forecast, these models could also help campaigns target programs for advertisements. Nearly two billion dollars were spent on television advertising in the 2012 presidential race, suggesting potential for big data-driven optimization of campaign spending.

Despite suggestions in the literature that depression has serious consequences, few studies have examined specific health and psychosocial outcomes of depression in Black single mothers. The purpose of this study was to estimate paths in a just-identified theoretical model of outcomes of depression for Black single mothers based on theoretical propositions and empirical findings. The model included the variables, depressive cognitions, depressive symptomatology, perceived social support, and positive health practices. Five direct and two indirect hypothesized relationships were estimated using structural equation modeling. A nonprobability sample of convenience of 159 Black single mothers aged 18 to 45 years was recruited for the study. This study used a cross-sectional correlational design. The participants responded in person or via the U.S. mail to the Center for Epidemiologic Studies-Depression scale, the Depressive Cognition Scale, the Personal Resource Questionnaire 85-Part 2, and the Personal Lifestyle Questionnaire. Beta and Gamma path coefficients were statistically significant for four out of five hypothesized direct relationships within the model (p < .01). The direct path between depressive cognitions and positive health practices was not supported (Gamma = -.11, p > .05). The two indirect paths were weak but statistically significant (p < .01). Depressive symptoms and perceived social support were outcomes of depressive cognitions. Positive health practices was not a direct outcome of depressive cognitions. Perceived social support and positive health practices were outcomes of depressive symptoms.

Although the association of fetal growth restriction and adverse pregnancy outcomes is well known, lack of sensitivity limits its clinical value. To a large extent, this limitation is a result of traditionally used method to define growth restriction by comparing fetal or birth weight to population norms. The use of population norms, by virtue of their inability to fully consider individual variation, results in high false positive and negative rates. An alternative, calculating fetal individually optimal growth potential, based on physiological determinants of individual growth, is superior in predicting adverse outcomes of pregnancy. Impairment of fetal growth potential identifes some adverse pregnancy outcomes that are not associated with growth restrction defined by population norms. When compared with traditional population-based norms, fetal growth potential is a better predictor of several important adverse outcomes of pregnancy which include: stillbirth, neonatal mortality and morbidity, and long-term adverse neonatal outcomes like neonatal encephalopathy, cerebral palsy and cognitive abilities. Impairment of individual growth potential is also strongly associated with spontaneous preterm delivery. Although definitive interventional trials have not been conducted as yet to validate the clinical value of fetal growth potential, many observational studies, conducted in various populations, indicate its significant promise in this respect.

Although several studies have examined the subcortical circuitry underlying Pavlovian-to-instrumental transfer (PIT), the role of medial prefrontal cortex in this behavior is largely unknown. Elucidating the cortical contributions to PIT will be key for understanding how reward-paired cues control behavior in both adaptive and maladaptive context…
The primary outcome measure is the outcome that an investigator considers to be the most important among the many outcomes that are to be examined in the study. The primary outcome needs to be defined at the time the study is designed. There are 2 reasons for this: it reduces the risk of false-positive errors resulting from the statistical testing of many outcomes, and it reduces the risk of a false-negative error by providing the basis for the estimation of the sample size necessary for an adequately powered study. This article discusses the setting of the primary outcome measure, the need for it, the increased risk of false-positive and false-negative errors in secondary outcome results, how to regard articles that do not state the primary outcome, how to interpret results when secondary outcomes are statistically significant but not the primary outcome, and limitations of the concept of a primary outcome measure in clinical trial research.

Randomization is firmly established as a cornerstone of clinical trial methodology. Yet, the ethics of randomization continues to generate controversy. The default, and most efficient, allocation scheme randomizes patients equally (1:1) across all arms of study. However, many randomized trials are using outcome-adaptive allocation schemes, which dynamically adjust the allocation ratio in favor of the better performing treatment arm. Advocates of outcome-adaptive allocation contend that it better accommodates clinical equipoise and promotes informed consent, since such trials limit patient-subject exposure to sub-optimal care. In this essay, we argue that this purported ethical advantage of outcome-adaptive allocation does not stand up to careful scrutiny in the setting of two-armed studies and/or early-phase research.

Several national evaluations have been conducted since the late 1960s that have assessed the effectiveness of publicly-funded substance abuse treatment in the United States. These studies, however, have focused principally on urban-based treatment programs, and it is unclear whether findings from urban programs can be replicated in outcome studies of programs in rural areas. The current study, therefore, examined the treatment outcomes of clients admitted to one of several short-term inpatient or outpatient drug-free treatment agencies in rural Kentucky. Findings showed that treatment was associated with reductions in drug use and criminality during a six-month follow-up interval. Employment status also improved significantly, and health services utilization was reduced. The similarity between the current findings and findings from national outcome studies of urban-based treatment programs is discussed.

Nursing informatics actively supports nursing by providing standard language systems, databases, decision support, readily accessible research results, and technology assessments. Through normalized datasets spanning an entire enterprise or other large demographic, nursing informatics tools support improvement of healthcare by answering questions about patient outcomes and quality improvement on an enterprise scale, and by providing documentation for business process definition, business process engineering, and strategic planning. Nursing informatics tools provide a way for advanced practice nurses to examine their practice and the effect of their actions on patient outcomes. Analysis of patient outcomes may lead to initiatives for quality improvement. Supported by nursing informatics tools, successful advance practice nurses leverage their quality improvement initiatives against the enterprise strategic plan to gain leadership support and resources.

During the last several decades, colorectal cancer surgery has experienced some major perioperative improvements. Preoperative risk-assessment of nutrition, frailty, and sarcopenia followed by interventions for patient optimization or an adapted surgical strategy, contributed to improved postoperative outcomes. Enhanced recovery programs or fast-track surgery also resulted in reduced length of hospital stay and overall complications without affecting patient safety. After an initially indecisive start due to uncertainty about oncological safety, the most significant improvement in intraoperative care was the introduction of laparoscopy. Laparoscopic surgery for colon and rectal cancer is associated with better short-term outcomes, whereas long-term outcomes regarding survival and recurrence rates are comparable. Nevertheless, long-term results in rectal surgery remain to be seen. Early recognition of anastomotic leakage remains a challenge, though multiple improvements have allowed better management of this complication. PMID:25253944

The cost of childhood stroke receives little notice. The authors examined potential drivers of cost and outcome to test whether (1) neonatal strokes cost less than childhood strokes, (2) associated diseases influence cost, (3) arterial ischemic stroke is more costly than sinovenous thrombosis, and (4) cost correlates with outcome. The authors reviewed records of 111 children who sustained arterial ischemic stroke or sinovenous thrombosis between 2005 and 2010 to identify costs for the following year. They assessed outcomes in 46 with the Recovery and Recurrence Questionnaire and the Pediatric Quality of Life Inventory. Neonatal strokes cost less than childhood stroke. Strokes associated with congenital heart disease or vasculopathy cost the most, while perinatal or idiopathic strokes cost the least. Higher costs are correlated with worse impairment and poorer quality of life. Stroke etiology significantly influences the cost of pediatric stroke. Future cost-benefit studies must consider etiology when estimating the incremental costs associated with stroke.

This review article summarizes the major studies that have investigated the outcomes of coronary artery bypass graft surgery (CABG). The article includes a review of the literature in the areas of: history of CABG; indications for CABG; and measurement of quality of life following CABG, including prolongation of life, physical functioning (ie, relief from angina and dyspnea, physical activity, as well as complications of surgery and re-hospitalization), psychological functioning, and social functioning. Overall, the literature demonstrates that the outcomes of CABG have historically been measured in terms of mortality and morbidity; however, it has now been well recognized that adjustment to CABG is a multidimensional phenomenon that is not fully explained by medical factors. Therefore, in addition to studying mortality and morbidity outcomes following CABG, many recent studies have identified that it is important to investigate various physical, psychological, and social variables that have a significant impact on post-operative adjustment to CABG.

We examined the extent to which nonhedonically different differential outcomes involving feeder location control pigeons' comparison choices in matching to sample. In Experiment 1, we showed that differential feeder location outcomes associated with each of two samples can facilitate delayed-matching accuracy. In Experiment 2, we found positive transfer following training on two matching tasks with differential feeder location outcomes when samples from one task were replaced by samples from the other task. In Experiment 3, we found that when differential-outcome expectations could no longer serve as the cues for comparison choice, sample stimuli continued to exert some control over choice of comparisons. The results indicate that differential outcomes (involving feeder location) that presumably do not differ in hedonic value are sufficient to control comparison choice. Thus, the differential hedonic value of the outcome elicited by the sample does not appear to be a requirement of the differential-outcome effect. Furthermore, these differential outcomes appear to augment matching accuracy, but they do not eliminate control by the samples.

Post-error slowing (PES) reflects efficient outcome monitoring, manifested as slower reaction time after errors. Cognitive control account assumes that PES depends on error information, whereas orienting account posits that it depends on error frequency. This raises the question how the outcome valence and outcome frequency separably influence the generation of PES. To address this issue, we varied the probability of observation errors (50/50 and 20/80, correct/error) the “partner” committed by employing an observation-execution task and investigated the corresponding behavioral and neural effects. On each trial, participants first viewed the outcome of a flanker-run that was supposedly performed by a ‘partner’, and then performed a flanker-run themselves afterwards. We observed PES in the two error rate conditions. However, electroencephalographic data suggested error-related potentials (oERN and oPe) and rhythmic oscillation associated with attentional process (alpha band) were respectively sensitive to outcome valence and outcome frequency. Importantly, oERN amplitude was positively correlated with PES. Taken together, these findings support the assumption of the cognitive control account, suggesting that outcome valence and outcome frequency are both involved in PES. Moreover, the generation of PES is indexed by oERN, whereas the modulation of PES size could be reflected on the alpha band. PMID:25732237

Objective To characterize the delivery and postnatal neurodevelopmental outcomes of fetuses referred for ventriculomegaly (VM). Methods Under an internal review board-approved protocol, pregnant women were referred for magnetic resonance imaging (MRI) after sonographic diagnosis of VM and classified into one of four diagnostic groups: Group 1, normal central nervous system (CNS); Group 2, isolated mild VM (10–12 mm); Group 3, isolated VM > 12 mm; and Group 4, other CNS findings. Pregnancy outcome was obtained. Follow-up visits were offered with assessment of neurodevelopmental, adaptive and neurological functioning at 6 months and 1 year and/or 2 years of age. Atrial diameter and VM group differences in developmental outcomes were evaluated using repeated measures logistic regression and Fishers exact test, respectively. Results Of 314 fetuses, 253 (81%) were liveborn and survived the neonatal period. Fetuses in Groups 4 and 3 were less likely to progress to live delivery and to survive the neonatal period (60% and 84%, respectively) than were those in Groups 2 or 1 (93% and 100%, respectively, P < 0.001). Of the 143 fetuses followed postnatally, between 41% and 61% had a Bayley Scales of Infant Development (BSID-II) psychomotor developmental index score in the delayed range (< 85) at the follow-up visits, whereas the BSID-II mental developmental index and Vineland Adaptive Behavior composite scores were generally in line with normative expectations. Among those that were liveborn, neither VM group nor prenatal atrial diameter was related to postnatal developmental outcome. Conclusions Diagnostic category and degree of fetal VM based on ultrasound and MRI measurements are associated with the incidence of live births and thus abnormal outcome. Among those undergoing formal postnatal testing, VM grade is not associated with postnatal developmental outcome, but motor functioning is more delayed than is cognitive or adaptive functioning.

It is well documented that high therapeutic doses of oxazaphosphorines, cyclophosphamide (CP) and ifosfamide (IFO), are associated with cardiomyopathy. This study investigated whether oxazaphosphorines alter the expression of organic cation/carnitine transporter (OCTN2) and antioxidant genes and if so, whether these alterations contribute to CP and IFO-induced cardiotoxicity. Adult male Wistar albino rats were assigned to one of six treatment groups namely, control, L carnitine, CP, IFO, CP plus L carnitine and IFO plus L carnitine. In cardiac and kidney tissues, CP and IFO significantly decreased mRNA and protein expression of OCTN2. Oxazaphosphorines significantly increased serum acyl-carnitine/free carnitine ratio and urinary carnitine excretion and significantly decreased total carnitine in cardiac tissues. Interestingly, carnitine supplementation completely reversed the biochemical and gene expression changes-induced by oxazaphosphorines to the control values, except OCTN2 expression remained inhibited by IFO. Data from this study suggest that: (1) Oxazaphosphorines decreased myocardial carnitine content following the inhibition of OCTN2 mRNA and protein expression in cardiac tissues. (2) Oxazaphosphorine therapy increased urinary loss of carnitine secondary to the inhibition of OCTN2 mRNA and protein expression in proximal tubules of the kidney. (3) Carnitine supplementation attenuates CP but not IFO-induced inhibition of OCTN2 mRNA and protein expression in heart and kidney tissues. PMID:22701146

Background: Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiac muscle disease with left ventricular hypertrophy, interstitial fibrosis and diastolic dysfunction. Increased myofilament Ca(2+) sensitivity could be the underlying cause of diastolic dysfunction. Epigallocatechin-3-gallate (EGCg), a catechin found in green tea, has been reported to decrease myofilament Ca(2+) sensitivity in HCM models with troponin mutations. However, whether this is also the case for HCM-associated thick filament mutations is not known. Therefore, we evaluated whether EGCg affects the behavior of cardiomyocytes and myofilaments of an HCM mouse model carrying a gene mutation in cardiac myosin-binding protein C and exhibiting both increased myofilament Ca(2+) sensitivity and diastolic dysfunction. Methods and Results: Acute effects of EGCg were tested on fractional sarcomere shortening and Ca(2+) transients in intact ventricular myocytes and on force-Ca(2+) relationship of skinned ventricular muscle strips isolated from Mybpc3-targeted knock-in (KI) and wild-type (WT) mice. Fractional sarcomere shortening and Ca(2+) transients were analyzed at 37°C under 1-Hz pacing in the absence or presence of EGCg (1.8 μM). At baseline and in the absence of Fura-2, KI cardiomyocytes displayed lower diastolic sarcomere length, higher fractional sarcomere shortening, longer time to peak shortening and time to 50% relengthening than WT cardiomyocytes. In WT and KI neither diastolic sarcomere length nor fractional sarcomere shortening were influenced by EGCg treatment, but relaxation time was reduced, to a greater extent in KI cells. EGCg shortened time to peak Ca(2+) and Ca(2+) transient decay in Fura-2-loaded WT and KI cardiomyocytes. EGCg did not influence phosphorylation of phospholamban. In skinned cardiac muscle strips, EGCg (30 μM) decreased Ca(2+) sensitivity in both groups. Conclusion: EGCg hastened relaxation and Ca(2+) transient decay to a larger extent in KI than in WT cardiomyocytes. This effect could be partially explained by myofilament Ca(2+) desensitization.

There is growing evidence that obesity is associated with poor outcomes in early stage breast cancer. This paper addresses four current areas of focus: 1. Is obesity associated with poor outcomes in all biologic subtypes of breast cancer? 2. Does obesity effect AI efficacy or estrogen suppression in the adjuvant setting? 3. What are the potential biologic underpinnings of the obesity-breast cancer association? 4. Are intervention studies warranted? If so, which interventions in which populations? Research is needed to resolve these questions; intervention trials involving lifestyle interventions or targeting the biology postulated to link obesity and cancer are recommended.
The impetus to pursue quality in limb salvage is high in the current economic environment. This has been spurred on by the diffusion of multiple technologies, the lack of well-defined cost-effectiveness benchmarks, and the paucity of process and structure benchmarks. Furthermore, no national database exists to capture current activity and trends, and lead structure and process changes that could analyze outcomes and improve standards in peripheral interventions for limb salvage. This manuscript examines the challenges in measuring outcomes and quality in limb salvage and explores the components necessary for ensuring quality in limb salvage interventions. PMID:23342183
Traditionally, the primary outcome of infertility trials has been a positive pregnancy test or a clinically recognized pregnancy. However, parents desire a healthy baby that grows up to be a healthy adult, rather than a positive pregnancy test. Too often results of infertility trials are lacking in crucial obstetric details. This is problematic because treatments for infertility have the capacity to increase the risk for a variety of adverse obstetric outcomes. This review will outline important obstetric variables that should be included when reporting infertility research. The rationale for including these data, precise definitions of the variables, and cost-effective strategies for obtaining these obstetric details will be highlighted.

Infant mortality rate (IMR) is a reference indicator for societal health status. Trend analysis of IMR highlights 2 challenges to overcome in the United States: (1) US IMR is higher than most industrialized countries and (2) there are persistent racial/ethnic disparities in birth outcomes, especially for blacks. Racial/ethnic infant mortality disparities result from the complex interplay of adverse social, economic, and environmental exposures. In this article, racial/ethnic disparities are discussed, highlighting trends, the role of epigenetics in understanding mechanisms, key domains of community action planning, and programs and policies addressing the racial gaps in adverse birth outcomes.

This report describes the course of psychiatric illness in two boys. Both presented with attention deficit hyperactivity disorder (ADHD) in midchildhood; after puberty, one boy developed a schizophrenic illness while the other boy developed a major affective illness. Although the major ADHD outcome studies have found no link between the childhood occurrence of ADHD and psychosis in adulthood, occasionally such a link may exist. The theoretical and practical implications of this finding are discussed. It should be noted, however, that such outcome is highly atypical and very rare.

Subdural haemorrhages (SDH) are associated with significant neurodisability in affected individuals. The incidence of SDH in infants is between 12 and 25 cases per 100 000 children and most detected SDH are due to physical abuse. In the infant brain, SDH are caused by tearing of the bridging veins in the subdural space and may result in significant brain injury. The challenge of assessing outcome in infants with SDH is evaluating whether SDH or other accompanying brain insults are instrumental in the neurodevelopmental outcome. PMID:17376941

Despite a lack of proven efficacy, pre-employment or pre-duty screening, which alleges to test for vulnerability to PTSD and other mental health disorders, remains common amongst emergency services. This systematic review aimed to determine the usefulness of different factors in predicting mental disorder amongst emergency workers and to inform practice regarding screening procedures. Systematic searches were conducted in MEDLINE, PsycINFO and EMBASE to identify cohort studies linking pre-employment or pre-duty measures in first responders with later mental health outcomes. Possible predictors of poor mental health were grouped into six categories and their overall level of evidence was assessed. Twenty-one prospective cohort studies were identified. Dynamic measures including physiological responses to simulated trauma and maladaptive coping styles (e.g. negative self-appraisal) had stronger evidence as predictors of vulnerability in first responders than more traditional static factors (e.g. pre-existing psychopathology). Personality factors (e.g. trait anger) had moderate evidence for predictive power. Based on the evidence reviewed, however, we are unable to provide emergency services with specific information to enhance their current personnel selection. The results indicate that pre-duty screening protocols that include personality assessments and dynamic measures of physiological and psychological coping strategies may be able to identify some personnel at increased risk of mental health problems. However, further longitudinal research is required in order to provide meaningful guidance to employers on the overall utility of either pre-employment or pre-duty screening. In particular, research examining the sensitivity, specificity and positive predictive values of various screening measures is urgently needed.

Background Network meta-analysis (NMA) enables simultaneous comparison of multiple treatments while preserving randomisation. When summarising evidence to inform an economic evaluation, it is important that the analysis accurately reflects the dependency structure within the data, as correlations between outcomes may have implication for estimating the net benefit associated with treatment. A multivariate NMA offers a framework for evaluating multiple treatments across multiple outcome measures while accounting for the correlation structure between outcomes. Methods The standard NMA model is extended to multiple outcome settings in two stages. In the first stage, information is borrowed across outcomes as well across studies through modelling the within-study and between-study correlation structure. In the second stage, we make use of the additional assumption that intervention effects are exchangeable between outcomes to predict effect estimates for all outcomes, including effect estimates on outcomes where evidence is either sparse or the treatment had not been considered by any one of the studies included in the analysis. We apply the methods to binary outcome data from a systematic review evaluating the effectiveness of nine home safety interventions on uptake of three poisoning prevention practices (safe storage of medicines, safe storage of other household products, and possession of poison centre control telephone number) in households with children. Analyses are conducted in WinBUGS using Markov Chain Monte Carlo (MCMC) simulations. Results Univariate and the first stage multivariate models produced broadly similar point estimates of intervention effects but the uncertainty around the multivariate estimates varied depending on the prior distribution specified for the between-study covariance structure. The second stage multivariate analyses produced more precise effect estimates while enabling intervention effects to be predicted for all outcomes, including

Several studies have suggested that surgical procedures performed at high-volume centers may result in superior outcome. Technically more demanding procedures such as aortic aneurysm repair appear to demonstrate a stronger relationship with volume. The present chapter reviewed the literature using the MEDLINE database to identify studies investigating the effect of volume in aortic aneurysm repair outcomes. The great majority of studies identified shows an advantage for high-volume hospitals with regard to perioperative mortality of abdominal (AAA), thoracic (TAA) and thoracoabdominal (TAAA) aortic aneurysm repair. A similar advantage is shown for high-volume surgeons. The volume advantage appears to be less evident for simple endovascular procedures (EVAR & TEVAR), compared to more complex endovascular (F/BEVAR) and open surgical procedures. Superior outcomes observed in high-volume hospitals are not only explained by increased surgeons' experience, but importantly also by a more effective management of intra- and postoperative complications. Confounding factors to be taken into account are the timing of the studies in relation to positive evolution of outcomes in several high-risk procedures, and patient cohorts selected in regions with very low- and very high-volume hospitals only.
Adverse outcome pathways (AOPs) are descriptive biological sequences that start from a molecular initiating event (MIE) and end with an adverse health outcome. AOPs provide biological context for high throughput chemical testing and further prioritize environmental health risk research. According to the Organization for Economic Co-operation and Development guidelines, AOPs are pathways with one MIE anchored to an adverse outcome (AO) by key events (KEs) and key event relationships (KERs). However, this approach does not always capture the cumulative impacts of multiple MIEs on the AO. For example, hepatic lipid flux due to chemical-induced toxicity initiates from multiple ligand-activated receptors and signaling pathways that cascade across biology to converge upon a common fatty liver (FL, also known as steatosis) outcome. To capture this complexity, a top-down strategy was used to develop a FL AOP network (AOPnet). Literature was queried based on the terms steatosis, fatty liver, cirrhosis, and hepatocellular carcinoma. Search results were analyzed for physiological and pathophysiological organ level, cellular and molecular processes, as well as pathway intermediates, to identify potential KEs and MIEs that are key for hepatic lipid metabolism, maintenance, and dysregulation. The analysis identified four apical KE nodes (hepatic fatty acid uptake, de novo fatty acid and lipid synthesis, fatty acid oxidation, and lipid efflux) juxtaposed to the FL AO. The apic

A robust anomaly in intertemporal choice is the delay-speedup asymmetry: Receipts are discounted more, and payments are discounted less, when delayed than when expedited over the same interval. We developed 2 versions of the tradeoff model (Scholten & Read, 2010) to address such situations, in which an outcome is expected at a given time but…

Background: Information on long-term prognosis in autism is limited. Outcome is known to be poor for those with an IQ below 50, but there have been few systematic studies of individuals with an IQ above this. Method: Sixty-eight individuals meeting criteria for autism and with a performance IQ of 50 or above in childhood were followed up as…

Examines growth parameters at birth in 204 infants born to mothers who used cocaine and/or opiates during pregnancy. Outcome measures included birth weight, length, and head circumference. Study provides support that in utero cocaine exposure may confer more risk for somatic growth retardation at birth than opiate exposure. (Author/GCP)
There is considerable debate about the relative importance of family versus school factors in producing academic and nonacademic student outcomes, and whether and how their impacts vary across different student groups. In addition to critically reviewing and synthesizing earlier work, this study extends the literature by (a) using the ECLS-K, a…
Much of the institutional research conducted at Harcum Junior College, a private women's college, has focused on measuring the educational outcomes of students in relation to the college's objectives. Past studies have sought to determine how well Harcum prepares transfer curriculum students by analyzing rates of baccalaureate degree attainment,…

Long-term follow-up of infants born prematurely is necessary to determine neurodevelopmental outcomes, particularly with the expansion of interest from major disabilities to high prevalence/low severity dysfunctions. Models of pathogenesis include changes due to developmental disruptions and to injury, the magnitude and type of change influenced by the infant's age, and central nervous system recovery and reorganization. Alterations in neurogenesis, migration, myelination, cell death, and synaptogenesis occur even in the absence of insult. Despite increased knowledge regarding these processes, the functional significance of brain abnormalities is unclear. Because of methodologic problems in follow-up studies, it is difficult to characterize outcome definitively. Nonetheless, an acceptable degree of agreement across studies is found with regard to specific neurodevelopmental outcomes: motor/neurologic function, visuomotor integrative skills, IQ, academic achievement, language, executive function, and attention-deficit hyperactivity disorder/behavioral issues. In general, children born prematurely have more problems in these areas than do their normal birth weight counterparts. Suggestions for improved analyses and clarification of outcomes include use of cluster analysis, structural equation modeling, growth curve analysis, developmental epidemiologic approaches, and better control of background variables using risk indexes and factor scores. Better assessment techniques measuring functions documented to be at higher risk of problems are discussed.
