RESUMEN
PURPOSE: Survival rates of lower extremity musculoskeletal tumours (LEMTs) have been increasing. However, patients continue to experience functional limitations after LEMT followed by limb-salvage surgery (LSS). This study aimed to identify factors influencing functional recovery after LSS for LEMT. METHODS: A qualitative study was conducted using semi-structured interviews with a purposive sample of adult patients who underwent LSS for LEMT (n=7) and healthcare professionals (HCPs) with expertise in orthopaedic oncology (n=7). Recruitment continued until data saturation. A combination of deductive and inductive qualitative content analysis was performed to analyse the transcribed data, producing subthemes under the main International Classification of Functioning, disability and health (ICF)-model domains. RESULTS: Four themes were described: (1) bodily functions and structures, (2) activities and participation, (3) environmental factors, and (4) expectations. Physical aspects such as larger resection size and complications negatively affected recovery. The importance of communication strategies of tertiary HCPs and the unfamiliarity of the primary physical therapists with the disease, its surgical treatment, and related consequences were emphasised by both the interviewed patients and HCPs. CONCLUSIONS: Functional recovery after LSS for LEMT is a multifactorial process. To improve patient care, improving (intercollegiate) communication strategies on treatment details and expectations about functional outcomes is warranted.Implications for rehabilitationHealthcare professionals should be aware some patients experience limited functional recovery after limb-salvage surgery (LSS) for lower extremity musculoskeletal tumours.Healthcare professionals should use multiple communication strategies to bridge the gap between the information provided and what the patient recalls.Knowledge exchange and communication between primary and tertiary care should be more extensive.Multidisciplinary consultations and/or case managers are needed to address all aspects of the individual's functional recovery after LSS.
RESUMEN
BACKGROUND: Heterogeneity and comorbidity in psychiatric disorders are common, however, little is known about the impact on well-being and the role of functional limitations. We aimed to identify transdiagnostic psychiatric symptom profiles and to study their association with well-being and the mediating role of functional limitations in a naturalistic psychiatric patient group. METHODS: We used four disorder-specific questionnaires to assess symptom severity within a sample of 448 psychiatric patients with stress-related and/or neurodevelopmental disorders and 101 healthy controls. Using both exploratory and confirmatory factor analyses we identified transdiagnostic symptom profiles, which we entered into a linear regression analysis to assess their association with well-being and the mediating role of functional limitations in this association. RESULTS: We identified eight transdiagnostic symptom profiles, covering mood, self-image, anxiety, agitation, empathy, non-social interest, hyperactivity and cognitive focus. Mood and self-image showed the strongest association with well-being in both patients and controls, while self-image also showed the highest transdiagnostic value. Functional limitations were significantly associated with well-being and fully mediated the relationship between cognitive focus and well-being. LIMITATIONS: The participant sample consisted of a naturalistic group of out-patients. While this strengthens the ecological validity and transdiagnostic perspective of this study, the patients with a single neurodevelopmental disorder were underrepresented. CONCLUSION: Transdiagnostic symptom profiles are valuable in understanding what reduces well-being in psychiatric populations, thereby opening new avenues for functionally meaningful interventions.

BACKGROUND: Anhedonia is apparent in different mental disorders and is suggested to be related to dysfunctions in the reward system and/or affect regulation. It may hence be a common underlying feature associated with symptom severity of mental disorders. METHODS: We constructed a cross-sectional graphical Least Absolute Shrinkage and Selection Operator (LASSO) network and a relative importance network to estimate the relationships between anhedonia severity and the severity of symptom clusters of major depressive disorder (MDD), anxiety sensitivity (AS), attention-deficit hyperactivity disorder (ADHD), and autism spectrum disorder (ASD) in a sample of Dutch adult psychiatric patients (N = 557). RESULTS: Both these networks revealed anhedonia severity and depression symptom severity as central to the network. Results suggest that anhedonia severity may be predictive of the severity of symptom clusters of MDD, AS, ADHD, and ASD. MDD symptom severity may be predictive of AS and ADHD symptom severity. CONCLUSIONS: The results suggest that anhedonia may serve as a common underlying transdiagnostic psychopathology feature, predictive of the severity of symptom clusters of depression, AS, ADHD, and ASD. Thus, anhedonia may be associated with the high comorbidity between these symptom clusters and disorders. If our results will be replicated in future studies, it is recommended for clinicians to be more vigilant about screening for anhedonia and/or depression severity in individuals diagnosed with an anxiety disorder, ADHD and/or ASD.

BACKGROUND: Individuals with a parental family history of dementia have an increased risk of developing dementia because they share their genes as well as their psychosocial behaviour. Due to this increased risk and their experience with dementia, they may be particularly eager to receive information regarding dementia risk reduction (DRR). This study evaluated the knowledge, beliefs and attitudes towards dementia and DRR among descendants of people with dementia. METHOD: Using a semi-structured topic guide, three focus group discussions were conducted consisting of 12 female (80%) and 3 male (20%) descendants of people with dementia with a mean (± SD) age of 48.8 (± 12) years. Focus group discussions were audio recorded and transcribed. Each transcript was analysed thoroughly, and where appropriate, a code was generated and assigned by two researchers independently. Then, similar codes were grouped together and categorized into themes. RESULTS: The items in the topic guide could only be addressed after participants had been given the opportunity to share their experiences of having a parent with dementia. Participants were unaware or uncertain about the possibility of reducing the risk of developing dementia and therefore hesitant to assess their dementia risk without treatment options in sight. Moreover, participants indicated that their general practitioner only gave some information on heritability, not on DRR. Although participants identified a large number of modifiable risk factors as a group during the group discussions, they were eager to receive more information on dementia and DRR. In the end, participants adopted a more positive attitude towards a DRR programme and provided suggestions for the development of future DRR programmes. CONCLUSIONS: Although the research aim was to evaluate the knowledge, beliefs and attitudes towards dementia and DRR, sharing experiences of having a parent with dementia seemed a prerequisite for considering participants' own risk of developing dementia and participating in a DRR programme. Knowledge of dementia and DRR was limited. Due to unawareness of the possibility of reducing dementia risk, participants were hesitant about assessing their dementia risk. Group discussions positively changed the perception of dementia risk assessment and participants' willingness to participate in a DRR programme.

BACKGROUND: Positive health beliefs and attitudes towards dementia and dementia risk reduction may encourage adopting a healthy behaviour. Therefore, we aimed to investigate the knowledge, health beliefs and attitudes towards dementia and dementia risk reduction among the Dutch general population and its association with the intention to change health behaviours. METHODS: A random sample of Dutch residents (30 to 80 years) was invited to complete an online survey. We collected data on knowledge, health beliefs and attitudes towards dementia (risk reduction) and the intention to change health behaviours. Multivariable logistic regression analyses were used to obtain effect estimates. RESULTS: Six hundred fifty-five participants completed the survey. In general, participants had insufficient knowledge about dementia and dementia risk reduction. Participants had relatively high scores on general health motivation and perceived benefits, but low scores on perceived susceptibility, perceived severity, perceived barriers, cues to action and self-efficacy. Individuals with higher scores on perceived benefits and cues to action had more often the intention to change their behaviour with regard to physical activity (OR = 1.33, 95%-CI:1.11-1.58; OR = 1.13, 95%-CI:1.03-1.24, respectively) and alcohol consumption (OR = 1.30, 95%-CI:1.00-1.69; OR = 1.17, 95%-CI:1.02-1.35, respectively). Younger excessive alcohol consumers with higher perceived severity scores had more often the intention to change their alcohol consumption behaviour (OR = 2.70, 95%-CI:1.04-6.97) compared to older excessive alcohol consumers. Opposite results were found for middle-aged excessive alcohol consumers (OR = 0.81, 95%-CI:0.67-0.99). Individuals who perceived more barriers had more often the intention to change their diet (OR = 1.10, 95%-CI:1.01-1.21), but less often the intention to change their smoking behaviour (OR = 0.78, 95%-CI:0.63-0.98). Moreover, less educated individuals with higher perceived benefits scores had less often the intention to change their diet (OR = 0.78, 95%-CI:0.60-0.99), while highly educated individuals with higher perceived benefits scores had more often the intention to change their diet (OR = 1.41, 95%-CI:1.12-1.78). CONCLUSIONS: The knowledge, beliefs and attitudes towards dementia and dementia risk reduction among the Dutch general population is insufficient to support dementia risk reduction. More education about dementia and dementia risk reduction is needed to improve health beliefs and attitudes towards dementia and dementia risk reduction in order to change health behaviour.

BACKGROUND: The Ruff Figural Fluency Test (RFFT) is a valid but time-consuming and labour-intensive cognitive paper-and-pencil test. A digital RFFT was developed that can be conducted independently using an iPad and Apple Pencil and RFFT scores are computed automatically. We investigated the validity and reliability of this digital RFFT. METHODS: We randomly allocated participants to the digital or paper-and-pencil RFFT. After the first test, the other test was performed immediately (cross-over). Participants were invited for a second digital RFFT 1 week later. For the digital RFFT, an (automatic) algorithm and two independent raters (criterion standard) assessed the number of unique designs (UD) and perseverative errors (PE). These raters also assessed the paper-and-pencil RFFT. We used Intraclass correlation coefficients (ICC), sensitivity, specificity, %-agreement, Kappa, and Bland-Altman plots. RESULTS: We included 94 participants (mean (SD) age 39.9 (14.8), 73.4% follow-up). Mean (SD) UD and median (IQR) PE of the digital RFFT were 84.2 (26.0) and 4 (2-7.3), respectively. Agreement between manual and automatic scoring of the digital RFFT was high for UD (ICC = 0.99, 95% CI 0.98, 0.99, sensitivity = 0.98; specificity = 0.96) and PE (ICC = 0.99, 95% CI 0.98, 0.99; sensitivity = 0.90, specificity = 1.00), indicating excellent criterion validity. Small but significant differences in UD were found between the automatic and manual scoring (mean difference: - 1.12, 95% CI - 1.92, - 0.33). Digital and paper-and-pencil RFFT had moderate agreement for UD (ICC = 0.73, 95% CI 0.34, 0.87) and poor agreement for PE (ICC = 0.47, 95% CI 0.30, 0.62). Participants had fewer UD on the digital than paper-and-pencil RFFT (mean difference: - 7.09, 95% CI - 11.80, - 2.38). The number of UD on the digital RFFT was associated with higher education (Spearman's r = 0.43, p < 0.001), and younger age (Pearson's r = - 0.36, p < 0.001), showing its ability to discriminate between different age categories and levels of education. Test-retest reliability was moderate (ICC = 0.74, 95% CI 0.61, 0.83). CONCLUSIONS: The automatic scoring of the digital RFFT has good criterion and convergent validity. There was low agreement between the digital RFFT and paper-and-pencil RFFT and moderate test-retest reliability, which can be explained by learning effects. The digital RFFT is a valid and reliable instrument to measure executive cognitive function among the general population and is a feasible alternative to the paper-and-pencil RFFT in large-scale studies. However, its scores cannot be used interchangeably with the paper-and-pencil RFFT scores.

BACKGROUND: Negative memory bias is a strong risk factor for the development and maintenance of depression. Recent evidence also found negative memory bias in other mental disorders. Here, we aim to: 1) assess the presence and strength of negative memory bias in a range of (comorbid) mental disorders, 2) investigate which disorder-specific symptoms are associated with negative memory bias, and 3) test whether negative memory bias might be a transdiagnostic mechanism. METHODS: Negative memory bias was measured in patients with at least one diagnosis of a stress-related disorder (n = 86), a neurodevelopmental disorder (n = 53), or both (n = 68), and 51 controls. Depression, anxiety, attention-deficit/hyperactivity disorder, and autism spectrum disorder symptom severity was assessed using questionnaires. Groups were compared on negative memory bias and the associations between negative memory bias and symptom severity were made using linear regression models. RESULTS: All patient groups showed stronger negative memory bias than the controls. Negative memory bias was individually associated with all symptom severity indices, but when added into a single model, only the association with depressive symptom severity remained. This persisted after controlling for diagnostic group. LIMITATIONS: Due to the cross-sectional sectional study design, we could only look at the associations between negative memory bias and disorder-specific symptoms and not at the direction of the effects. CONCLUSIONS: Negative memory bias is characteristic of a depressotypic processing style and present in different mental disorders. It might play a mechanistic role in the development of (subclinical) co-occurrence between mental disorders.

BACKGROUND: Most mental health hospitals in the Netherlands use disorder specific standards of care. In case of comorbidity, we lack evidence in choosing the treatment of preference when both depressive- and anxiety disorder(s) are present in the same patient.
AIM: To investigate the prevalence of depression and anxiety (including obsessive compulsive disorder and post-traumatic stress disorder) in an outpatient mental health hospital population treated for their anxiety disorder, and to investigate the difference in outcome of (anxiety) treatment between patients with and without a comorbid depressive disorder.
METHOD: A retrospective study using outcome data from 2012 to 2017. In this period, we identified 127 patients for whom outcome data and diagnostic criteria were available. Comorbidity in this group was determined by a clinical interview. During treatment symptoms were monitored using self-reporting scales, among others the Inventory of Depressive Symptomatology (IDS) and the Beck Anxiety Inventory (BAI).
RESULTS: In 46,5% of the patients a comorbid depressive disorder was diagnosed. No significant difference in treatment outcome was observed between the group of patients with and the group of patients without a comorbid depressive disorder. However, the amount of reduction of depressive symptoms measured by the ids was a good predictor of the reduction of anxiety: a faster reduction of depressive symptoms predicts a better outcome of the treatment of anxiety.
CONCLUSION: Comorbid depressive disorders were observed in almost half of the patients treated in specialized (outpatient) clinics for anxiety disorders. A slower reduction of depressive symptoms predicts worse outcome of the treatment of anxiety.

Clinically, it is well-established that vulnerability to stress is a common feature across a broad spectrum of psychiatric disorders. However, this link has been mechanistically studied almost exclusively in patients with so-called stress-related disorders such as depression and anxiety. To probe transdiagnostic mechanisms, we set out to study the acute stress response across a broader range of psychiatric disorders taking a large-scale brain network perspective. We investigated the brain's response to a mild, experimentally well-controlled psychological stressor in the form of an aversive movie. We studied 168 patients with stress-related and/or neurodevelopmental disorders (including comorbidity) and 46 control subjects. We focused on three networks that have a central role in the brain's stress response and are affected in a wide range of psychiatric disorders: the salience network (SN), default mode network (DMN) and frontoparietal network (FPN). Our results support an increased vulnerability to stress across all patients, indicated by a higher subjective stress level at baseline and follow-up compared to matched controls. At the brain systems level, the stress response was characterized by a relatively decreased FPN connectivity and an absence of a decrease in the within DMN connectivity across all disorders compared to controls. At the neurocognitive level, these findings may reflect a diminished top-down control and a tendency to more pronounced (negative) self-referential processing. Besides these shared aspects of the maladaptive stress response, we also discuss indications for disorder-specific aspects. Taken together, our results emphasize the importance of investigating the mechanistic underpinnings of psychiatric disorders transdiagnostically as recently done in neurogenetics.

Major depressive disorder is a prevalent condition with high relapse rates. There is evidence that cognitive reactivity is an important vulnerability factor for the recurrence of depression. Mindfulness-based interventions are designed to reduce relapse rates, with cognitive reactivity as one of the proposed working mechanisms. In a randomised controlled trial we compared the effect of mindfulness-based cognitive therapy (MBCT) with treatment-as-usual (TAU) on cognitive reactivity in recurrently depressed patients (N = 115). Depressive symptoms, cognitive reactivity, and mindfulness skills were assessed pre and post treatment. Patients in the MBCT group reported a significantly greater reduction in cognitive reactivity than those in the TAU group (d = .51). The reduction of cognitive reactivity appeared to mediate the association between MBCT/TAU and decrease of depressive symptoms, using pre and post scores. The current study provides evidence that MBCT reduces cognitive reactivity and preliminary evidence that cognitive reactivity is a working mechanism of MBCT.

The brain-derived neurotrophic factor (BDNF) and catechol-O-methyltransferase (COMT) genes are relevant candidates for depression. Variation in these genes is associated with stress sensitivity and depressotypic cognitive biases. The interaction between genes and stressful events is considered as an important mechanism in the development of depression. This study examined the effects of the BDNF and COMT genes on biased processing and the interaction with childhood stress in vulnerable individuals. A total of 198 remitted depressed individuals performed an n-back task with emotional facial stimuli (happy and sad). Childhood events were measured with a questionnaire. Genotype by childhood events interactions were analyzed for happy and sad expressions for BDNF (Val66Met; rs6265) and COMT (Val158Met; rs4680), individually and combined. BDNF and COMT both interacted significantly (P = 0.006 and P = 0.014, respectively) with childhood trauma on reaction time for happy faces. For both genes, Met-carriers with childhood trauma showed less positive bias for happy faces than those without childhood trauma. Val-carriers did not show a differential bias. Individuals with childhood trauma and 3 or 4 risk alleles (BDNF and COMT combined) showed less positive bias than those without childhood trauma (P = 0.011). The BDNF × COMT × childhood trauma interaction yielded a P = 0.055, but had limited power. A potential weakness is the measurement method of the childhood events, as negative bias might have affected participants' recall. Our findings endorse the association of BDNF and COMT with stress and depression and provide a possible intermediate, i.e. biased processing of positive information. Tailoring treatment to specific risk profiles based on genetic susceptibility and childhood stress could be promising.
