Does depression influence the postoperative result of total hip arthroplasties?

Chronic pain and functional limitations caused by coxarthrosis are important factors in the onset of depression, as there are higher rates of depression in this group of patients than in the general population. Total hip arthroplasty (THA) has been shown to decrease pain and improve function in these patients, which may positively influence the patient's depressive symptoms. The objectives of the study are to evaluate the differences between patients with depression and patients without depression in the immediate postoperative period (pain and hospitalization time) and to evaluate functional outcomes one year after surgery. Therefore, we conducted a prospective cohort study in which all patients with indications for primary total hip arthroplasty during 2018 were included. Preoperatively, patients completed the PHQ-9 questionnaire, and were classified into patients with depression (if preoperative PHQ-9 > or = to 10) and patients without depression (pre PHQ-9 < to 10). During the hospital stay, postoperative pain was assessed by VAS, and the need for analgesic rescue with major opioids. One year after surgery, the PHQ-9 test was retaken, and functional outcomes were assessed. The results showed that both groups were comparable in terms of sex, age, BMI, and ASA. No differences were found in postoperative pain or hospitalization time. There were also no differences between the two groups of patients in functional outcomes one year after surgery. Therefore, we can conclude that patients with a diagnosis of depression do not present worse postoperative pain after THA. In addition, they show a significant improvement in their depressive symptoms one year after surgery.

Sensation-seeking-related DNA methylation and the development of delinquency: A longitudinal epigenome-wide study.

Heightened sensation-seeking is related to the development of delinquency. Moreover, sensation-seeking, or biological correlates of sensation-seeking, are suggested as factors linking victimization to delinquency. Here, we focused on epigenetic correlates of sensation-seeking. First, we identified DNA methylation (DNAm) patterns related to sensation-seeking. Second, we investigated the association between sensation-seeking related DNAm and the development of delinquency. Third, we examined whether victimization was related to sensation-seeking related DNAm and the development of delinquency. Participants (N = 905; 49% boys) came from the Avon Longitudinal Study of Parents and Children. DNAm was assessed at birth, age 7 and age 15-17. Sensation-seeking (self-reports) was assessed at age 11 and 14. Delinquency (self-reports) was assessed at age 17-19. Sensation-seeking epigenome-wide association study revealed that no probes reached the critical significance level. However, 20 differential methylated probes reached marginal significance. With these 20 suggestive sites, a sensation-seeking cumulative DNAm risk score was created. Results showed that this DNAm risk score at age 15-17 was related to delinquency at age 17-19. Moreover, an indirect effect of victimization to delinquency via DNAm was found. Sensation-seeking related DNAm is a potential biological correlate that can help to understand the development of delinquency, including how victimization might be associated with adolescent delinquency.

Perceived Support from Best Friends and Depressive Symptoms During Adolescence: Disentangling Personal from Dyadic Level Effects.

Support from best friends is an important interpersonal factor in adolescent depression development but is often studied from an individual perspective in which dyadic effects are overlooked. This study aims to a) test whether differences in support vary at the individual level and are related to individual differences in the development of depressive symptoms, whether these differences vary at the dyadic level and are related to dyadic depression symptom development, or both, b) explore whether these associations are moderated by initial levels of depressive symptoms on the individual and/or dyadic level. Data from 452 adolescents (Mage = 13.03), nested in 226 same-gender friendship dyads (60.6% boy-dyads) who participated in the RADAR-Y project were included. Best friends self-reported annually (2006-2008; 3 waves) on their own depressive symptoms and perceived support from their friend. Multilevel models showed no direct association between support and depression development on the individual or dyadic level. However, the initial level of dyads' depressive symptoms moderated the association between dyadic support and dyads' subsequent depression symptom development. When dyads experienced relatively more initial depressive symptoms, higher levels of dyadic support were associated with relative increasing dyadic depressive symptoms. When dyads experienced relatively few initial depressive symptoms, higher levels of dyadic support were associated with relative decreasing dyadic depressive symptoms. Findings suggest that support from best friends can either protect against or exacerbate the development of depressive symptoms for friends, depending on the initial level of depressive symptoms of the dyad.

Moderators of an intervention on emotional and behavioural problems: household- and school-level parental education.

BACKGROUND: Children of lower-educated parents and children in schools with a relatively high percentage of peers with lower-educated parents (lower parental education schools) are more likely to develop emotional and behavioural problems compared to children in higher-educated households and schools. Universal school-based preventive interventions, such as the Good Behaviour Game (GBG), are generally effective in preventing the development of emotional and behavioural problems, but information about potential moderators is limited. This study examined whether the effectiveness of the GBG in preventing emotional and behavioural problems differs between children in lower- and higher-educated households and schools. METHODS: Using a longitudinal multi-level randomized controlled trial design, 731 children (Mage=6.02 towards the end of kindergarten) from 31 mainstream schools (intervention arm: 21 schools, 484 children; control arm: 10 schools, 247 children) were followed annually from kindergarten to second grade (2004-2006). The GBG was implemented in first and second grades. RESULTS: Overall, the GBG prevented the development of emotional and behavioural problems. However, for emotional problems, the GBG-effect was slightly more pronounced in higher parental education schools than in lower parental education schools (Bhigher parental education schools =-0.281, P <0.001; Blower parental education schools =-0.140, P = 0.016). No moderation by household-level parental education was found. CONCLUSIONS: Studies into universal school-based preventive interventions, and in particular the GBG, should consider and incorporate school-level factors when studying the effectiveness of such interventions. More attention should be directed towards factors that may influence universal prevention effectiveness, particularly in lower parental education schools.

Children's behavioral and emotional problems and peer relationships across elementary school: Associations with individual- and school-level parental education.

This study examined (a) whether growing up with lower-educated parents and attending lower parental education schools associated with children's problem development within the behavioral, emotional, and peer relationship domains; and (b) whether the association of lower individual-level parental education with children's development within these three domains depended upon school-level parental education. To this end, 698 children (Mage = 7.08 in first grade) from 31 mainstream elementary schools were annually followed from first grade to sixth grade. Problems within the behavioral domain included conduct problems, oppositional defiant problems, attention-deficit and hyperactivity problems, and aggression. Problems within the emotional domain included depression and anxiety symptoms. Problems within the peer relationship domain included physical victimization, relational victimization, and peer dislike. Results from multi-level latent growth models showed that, as compared to children of higher-educated parents, children of lower-educated parents generally had higher levels of problems within all three domains in first grade and exhibited a faster growth rate of problems within the behavioral domain from first to sixth grade. Furthermore, as compared to children attending higher parental education schools, children attending lower parental education schools generally had higher levels of problems within the behavioral and emotional domains in first grade and showed a faster growth rate of peer dislike over time. In addition, cross-level interaction analyses showed that in higher parental education schools, children of lower-educated parents showed a faster growth rate of depression symptom levels than children of higher-educated parents. In lower parental education schools, the growth rate of depression symptom levels did not differ between children of higher- and lower-educated parents. Results highlight that addressing the needs of lower parental education schools and children growing up with lower-educated parents may be of primary importance.

Diminished error-related negativity and error positivity in children and adults with externalizing problems and disorders: a meta-analysis on error processing.

BACKGROUND: Deficits in error processing are reflected in an inability of people with externalizing problems to adjust their problem behaviour. The present study contains 2 meta-analyses, testing whether error processing - indexed by the event-related potentials error-related negativity (ERN) and error positivity (Pe) - is reduced in children and adults with externalizing problems and disorders compared to healthy controls. METHODS: We conducted a systematic search in PubMed (1980 to December 2018), PsycInfo (1980 to December 2018) and Scopus (1970 to December 2018), identifying 328 studies. We included studies that measured error processing using the Eriksen flanker task, the go/no-go task or the stop-signal task in healthy controls and in adults or children with clearly described externalizing behavioural problems (e.g., aggression) or a clinical diagnosis on the externalizing spectrum (e.g., addiction). RESULTS: Random-effect models (ERN: 23 studies, 1739 participants; Pe: 27 studies, 1456 participants) revealed a reduced ERN amplitude (Hedges' g = 0.44, 95% confidence interval [CI] 0.29 to 0.58) and a reduced Pe amplitude (Hedges' g = -0.27, 95% CI -0.44 to -0.09) during error processing in people with externalizing problems or disorders compared to healthy controls. Type of diagnosis, age and the presence of performance feedback or comorbidity did not moderate the results. The employed cognitive task was a moderator for Pe but not for ERN. The go/no-go task generated a greater amplitude difference in Pe than the Eriksen flanker task. Small-sample assessment revealed evidence of publication bias for both event-related potentials. However, a p curve analysis for ERN showed that evidential value was present; for Pe, the p curve analysis was inconclusive. LIMITATIONS: The moderators did not explain the potential heterogeneity in most of the analysis, suggesting that other disorder- and patient-related factors affect error processing. CONCLUSION: Our findings indicate the presence of compromised error processing in externalizing psychopathology, suggesting diminished activation of the prefrontal cortex during performance monitoring.

Developmental associations between risk-taking and anxiety symptoms across ages 8-12 years.

This study explored the transactional association between anxiety symptoms and risk-avoidance in Dutch elementary schoolchildren (N = 1200; 50% girls) across ages 8-12. Anxiety symptoms were obtained using self-, peer-, and teacher-reports. Risk-avoidance was measured using the Balloon Analogue Risk Task-Youth Version. Random-intercept cross-lagged panel models showed that, across informants, increases in anxiety symptoms predicted decreases in risk-taking. Apart from minor exceptions, this effect was similar across sexes. For peer-reports, the reverse path from decreases in risk-taking to increased anxiety was also found. Overall, this study gives insight into the developmental link between symptoms of anxiety and risk-avoidance which is important for early signaling and prevention as well as for our understanding of the consequences of childhood anxiety symptoms.

Lassa-VSV chimeric virus targets and destroys human and mouse ovarian cancer by direct oncolytic action and by initiating an anti-tumor response.

Ovarian cancer is the third most common female cancer, with poor survival in later stages of metastatic spread. We test a chimeric virus consisting of genes from Lassa and vesicular stomatitis viruses, LASV-VSV; the native VSV glycoprotein is replaced by the Lassa glycoprotein, greatly reducing neurotropism. Human ovarian cancer cells in immunocompromised nude mice were lethal in controls. Chemotherapeutic paclitaxel and cisplatin showed modest cancer inhibition and survival extension. In contrast, a single intraperitoneal injection of LASV-VSV selectively infected and killed ovarian cancer cells, generating long-term survival. Mice with human ovarian cancer cells in brain showed rapid deterioration; LASV-VSV microinjection into brain blocked cancer growth, and generated long-term survival. Treatment of immunocompetent mice with infected mouse ovarian cancer cells blocked growth of non-infected ovarian cancer cells peritoneally and in brain. These results suggest LASV-VSV is a viable candidate for further study and may be of use in the treatment of ovarian cancer.

Exposure to Bullying and General Psychopathology: A Prospective, Longitudinal Study.

Although there is mounting evidence that the experience of being bullied associates with both internalizing and externalizing symptoms, it is not known yet whether the identified associations are specific to these symptoms, or shared between them. The primary focus of this study is to assess the prospective associations of bullying exposure with both general and specific (i.e., internalizing, externalizing) factors of psychopathology. This study included data from 6,210 children participating in the Avon Longitudinal Study of Parents and Children (ALSPAC). Child bullying was measured by self-report at ages 8 and 10 years. Child psychopathology symptoms were assessed by parent-interview, using the Development and Well-being Assessment (DAWBA) at ages 7 and 13 years. Bullying exposure significantly associated with the general psychopathology factor in early adolescence. In particular, chronically victimized youth exposed to multiple forms of bullying (i.e., both overt and relational) showed higher levels of general psychopathology. Bullying exposure also associated with both internalizing and externalizing factors from the correlated-factors model. However, the effect estimates for these factors decreased considerably in size and dropped to insignificant for the internalizing factor after extracting the shared variance that belongs to the general factor of psychopathology. Using an integrative longitudinal model, we found that higher levels of general psychopathology at age 7 also associated with bullying exposure at age 8 which, in turn, associated with general psychopathology at age 13 through its two-year continuity. Findings suggest that exposure to bullying is a risk factor for a more general vulnerability to psychopathology.

Early childhood internalizing problems, externalizing problems and their co-occurrence and (mal)adaptive functioning in emerging adulthood: a 16-year follow-up study.

PURPOSE: A vast amount of studies suggest that internalizing or externalizing problems are related to individual functioning, and often co-occur. Yet, a focus on their additive and interactive effects is scarce. Furthermore, most research has focused on a limited number of developmental domains and mostly on maladaptive functioning. Therefore, the current prospective study examined whether early childhood (ages 4-8) internalizing and externalizing problems and their interaction were related to a broad range of (mal)adaptive functioning outcomes in emerging adulthood (ages 20-24). METHODS: Data from the Flemish Study on Parenting, Personality and Development were used. At Time 1 (1999) mothers of 374 children (45% boys) and fathers of 357 children (46% boys) rated internalizing and externalizing problems through the Child Behavior Checklist. Outcomes in emerging adulthood were measured through self-reports 16 years later across the following domains: psychological functioning, social functioning, work, physical health, and self-concept. RESULTS: Early externalizing problems were related to maladaptive outcomes on the psychological and social domains. With regard to adaptive functioning, externalizing problems were associated with lower satisfaction regarding general health on the physical domain. Early internalizing problems were not associated with any emerging adulthood outcomes. The interaction of (father reported) internalizing and externalizing problems was related to aggressive behavior. CONCLUSION: Early childhood externalizing problems were associated with maladaptive and adaptive functioning over a time span of 16 years. The results add to studies on the implementation of prevention and intervention programs in early childhood and to the value for developing personalized interventions.

[The value of booster vaccination against COVID-19]. / Boostervaccinatie tegen covid-19.

The first vaccines against Covid-19 were approved in December 2020 and administered in the Netherlands from the beginning of January 2021. As of November 2021, The Dutch government has started its booster programme to administer an additional vaccine dose to the population.This paper discusses the current knowledge about the duration of protection of the Covid-19 vaccines that are used in the Netherlands, and the added value of booster vaccination.

Prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Trichomonas vaginalis including relevant resistance-associated mutations in a single center in the Netherlands.

PURPOSE: In this study, we report the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG) and Trichomonas vaginalis (TV) amongst clinical specimens of patients suspected for sexually transmitted infections received at our laboratory and in addition report the prevalence of resistance-associated mutations (RAM) for ciprofloxacin in NG and azithromycin and moxifloxacin in MG. METHODS: All specimens received from December 2018 to May 2019 were tested for the four pathogens. In addition, the presence of RAM associated with resistance to ciprofloxacin in NG and to azithromycin and moxifloxacin in MG was determined by different real-time PCR assays on all NG- and MG-positive specimens. RESULTS: CT was detected most often (267/2613, 10.2%), followed by MG (106/2592, 4.1%), NG (41/2613, 1.6%) and TV (10/2592, 0.4%) amongst all specimens. The prevalence of ciprofloxacin RAM in NG was 21.2%, and the prevalence of RAM in MG was 40.6% for azithromycin and 8.1% for moxifloxacin. Nearly all specimens containing moxifloxacin-resistant MG also contained azithromycin-resistant MG. CONCLUSION: CT is found most often in our population followed by MG and NG. By using molecular assays to detect RAM supplementary to pathogen identification of NG and MG, optimal therapy can be advised.

Heightened neural sensitivity to social exclusion in boys with a history of low peer preference during primary school.

Peer preference among classmates is a highly influential factor in children's social development and not being preferred by peers has long-term consequences for children's developmental outcomes. However, little is known about how a history of low peer preference during primary school is associated with neural responses to a new social exclusion experience in childhood. In this functional magnetic resonance imaging (fMRI) study, we examined self-reported social distress and neural responses to social exclusion using the Cyberball paradigm in primary school boys (Mage = 10.40 years) with a history of low (n = 27) versus high peer preference (n = 28). Boys were selected from a longitudinal classroom-based study in which children's peer social preferences were assessed in three consecutive years prior to this study. Neuroimaging results showed that low peer preferred boys exhibited increased activation in the lateral prefrontal cortex during early social exclusion relative to later social exclusion experiences as compared to high peer preferred boys. Increased neural activity was not accompanied by higher self-reported levels of social distress during social exclusion in low versus high peer preferred children. Findings of this study may provide insight into the neural processes associated with real-life peer experiences in children attending primary school.

Cardiac foetal reprogramming: a tool to exploit novel treatment targets for the failing heart.

As the heart matures during embryogenesis from its foetal stages, several structural and functional modifications take place to form the adult heart. This process of maturation is in large part due to an increased volume and work load of the heart to maintain proper circulation throughout the growing body. In recent years, it has been observed that these changes are reversed to some extent as a result of cardiac disease. The process by which this occurs has been characterized as cardiac foetal reprogramming and is defined as the suppression of adult and re-activation of a foetal genes profile in the diseased myocardium. The reasons as to why this process occurs in the diseased myocardium are unknown; however, it has been suggested to be an adaptive process to counteract deleterious events taking place during cardiac remodelling. Although still in its infancy, several studies have demonstrated that targeting foetal reprogramming in heart failure can lead to substantial improvement in cardiac functionality. This is highlighted by a recent study which found that by modulating the expression of 5-oxoprolinase (OPLAH, a novel cardiac foetal gene), cardiac function can be significantly improved in mice exposed to cardiac injury. Additionally, the utilization of angiotensin receptor neprilysin inhibitors (ARNI) has demonstrated clear benefits, providing important clinical proof that drugs that increase natriuretic peptide levels (part of the foetal gene programme) indeed improve heart failure outcomes. In this review, we will highlight the most important aspects of cardiac foetal reprogramming and will discuss whether this process is a cause or consequence of heart failure. Based on this, we will also explain how a deeper understanding of this process may result in the development of novel therapeutic strategies in heart failure.

Associations between peer attachment and neural correlates of risk processing across adolescence.

Adolescence is a period of increased risk-taking behavior where individual differences in risk taking may relate to both adverse and positive experiences with peers. Yet, knowledge on how risk processing develops in the adolescent brain and whether this development is related to peer attachment is limited. In this longitudinal functional magnetic resonance imaging (fMRI) study, we collected data from 167 adolescents (53% male) followed for four annual assessments across ages 13-17 years. At each assessment, participants completed a lottery choice task to assess neural risk processing and reported on their perceived attachment to peers and parents. Behaviorally, risk-preference on the lottery choice task decreased linearly with age. Neural activation during risk processing was consistently found in the insula and dACC across the four assessments and increased linearly from ages 13-17 years. Furthermore, higher peer attachment was related to greater right insula risk processing for males but not for females, even after controlling for parental attachment. The magnitudes of this association did not change with age. Findings demonstrate that neural risk processing shows maturation across adolescence and high peer attachment may be associated with low risk taking by heightening neural sensitivity to potential risks for male adolescents.

Author Correction: GWAS of lifetime cannabis use reveals new risk loci, genetic overlap with psychiatric traits, and a causal effect of schizophrenia liability.

Several occurrences of the word 'schizophrenia' have been re-worded as 'liability to schizophrenia' or 'schizophrenia risk', including in the title, which should have been "GWAS of lifetime cannabis use reveals new risk loci, genetic overlap with psychiatric traits, and a causal effect of schizophrenia liability," as well as in Supplementary Figures 1-10 and Supplementary Tables 7-10, to more accurately reflect the findings of the work.

Heightened neural sensitivity to social exclusion in boys with a history of low peer preference during primary school.

Peer preference among classmates is a highly influential factor in children's social development and not being preferred by peers has long-term consequences for children's developmental outcomes. However, little is known about how a history of low peer preference during primary school is associated with neural responses to a new social exclusion experience in childhood. In this functional magnetic resonance imaging (fMRI) study, we examined self-reported social distress and neural responses to social exclusion using the Cyberball paradigm in primary school boys (Mage = 10.40 years) with a history of low (n = 27) versus high peer preference (n = 28). Boys were selected from a longitudinal classroom-based study in which children's peer social preferences were assessed in three consecutive years prior to this study. Neuroimaging results showed that low peer preferred boys exhibited increased activation in the bilateral dorsolateral prefrontal cortex and right supramarginal gyrus during social exclusion as compared to high peer preferred boys. Increased neural activity was not accompanied by higher self-reported levels of social distress during social exclusion in low versus high peer preferred boys. Findings of this study may provide insight into the neural processes associated with real-life peer experiences in children attending primary school.

Searching for bodies: ERP evidence for independent somatosensory processing during visual search for body-related information.

Attention allows us to select relevant information by modulating neural activity within sensory brain areas processing that information. Previous research has shown that visual perception of body stimuli recruits visual cortices together with observer's body representation in somatosensory cortex, which is known for processing body-related information (e.g., haptics, kinematics). However, whether attentional selection of visual body stimuli involves just visual or additional somatosensory areas remains elusive. Here we elicited visual and somatosensory evoked activity during a visual search task, whereby participants searched for target hand images defined by either visual (colour) or bodily (posture) features. In line with previous studies, we found electrophysiological evidence for attentional selection over visual areas (i.e., N2pc) regardless of the feature type. Importantly, after dissociating somatosensory from visual evoked activity, we show that only attentional selection of hand posture - but not hand colour - elicits modulation of somatosensory evoked electrocortical activity over somatosensory cortex. This suggests that attention may not only modulate cortical activity associated with the input-sensory modality (in this case, visual), but, depending on the type of attended information, it may also modulate cortical activity associated with another task-relevant sensory modality (in this case, somatosensory). Overall, our results provide evidence for a flexible attention mechanism that operates according to specific behavioural goals and the information embedded in the percept.

Oxytocin Receptor Gene (OXTR) and Deviant Peer Affiliation: A Gene-Environment Interaction in Adolescent Antisocial Behavior.

Although the oxytocin receptor gene (OXTR) is involved in aggression and social affiliation, it has not been examined in gene-environment interaction studies. This longitudinal study examined the effect of genetic variants in OXTR and its gene-environment interaction with perceived deviant peer affiliation in the trajectories of antisocial behavior in 323 adolescents (182 males) from 13 to 18 years. Annual assessments of reactive and proactive aggression, delinquency, and friends' delinquency, as well as DNA at age 17 were collected. Gene-based tests yielded no main effect of OXTR, but revealed a significant gene-environment interaction in proactive aggression and delinquency. Variation in the OXTR might affect the influence of deviant peer affiliation on antisocial behavior, contributing to a better understanding of individual differences in antisocial behavior.

Violence and aggression in the intensive care unit: What is the impact of Australian National Emergency Access Target?

INTRODUCTION: Violence in healthcare settings is a concern for healthcare professionals and patients. Media reports, and debate within the healthcare profession, and the academic literature infer that workplaces such as intensive care units are becoming exposed to increasing violence. Increases in the incidence of violent behaviour are sometimes attributed to the increased pressure on emergency departments to accelerate the throughput of patients to meet targets. To ensure the wellbeing of patients and staff, there is a need to evaluate the impact of such targets. The aim in this study was to evaluate the incidence and to describe the context in which patients' aggressive and violent behaviours occurred since the introduction of the National Emergency Access Target in a local tertiary Australian intensive care unit. METHODS: A retrospective examination of events triggering violence-related emergency codes from 12 months before the introduction of the National Emergency Access Target up until 12 months after its implementation (2011-2013). RESULTS: A small increase in the number of Code Grey/Code Black activation was identified after the introduction of the target (before = 18, after = 29). Admissions following drug overdoses, isolated head trauma, and cardiac arrest were the presentations most likely to have been associated with a violence-related emergency call. Female registered nurses, male critical care registered nurses, and clinical nurse specialists were the most at risk of occupational violence. Male nursing staff members were found to be more likely to be involved in incidences of verbal violence (p < 0.003). CONCLUSION: Although there was a minimal increase in the overall number of emergencies triggered by violent behaviour, valuable information on the type of occupational violence occurring towards healthcare professionals and patients in this setting was found. We suggest that these findings add further important detail to the existing understanding of the problem of occupational violence. These detailed insights can further inform policy development, professional education, and practice.
