The online mindset intervention 'The Growth Factory' for adolescents with intellectual disabilities: moderators and mediators.

BACKGROUND: The online mindset intervention The Growth Factory (TGF) has shown promising effects-increasing growth mindsets and perseverance and decreasing mental health problems among youth with intellectual disabilities (ID). Studying moderators and mediators of intervention effects is essential to elucidate for whom and why TGF works. Using a randomised controlled trial design, we examined youth's baseline mindset, gender, age, level of ID and intervention satisfaction as moderators of TGF effects and examined whether the intervention effects of TGF on improvements in mental health were mediated by perseverance. METHODS: The sample consisted of 119 participants with mild to borderline ID (Mage  = 15.83; SD = 2.23), randomly assigned to the intervention (n = 60) or passive control group (n = 59). Participants reported mindsets, perseverance, internalising, externalising, attention and total mental health problems at pre-test, at post-test and at 3-month follow-up. Additionally, youth in the intervention group graded their satisfaction with a score at the end of each session. RESULTS: Findings indicated that the effectiveness of TGF was not affected by participants' baseline mindsets, age and ID level. TGF was more effective in reducing internalising problems in girls and increasing perseverance in boys. In addition, in the intervention group TGF was more effective in improving internalising, externalising and total mental health problems for youth who reported higher levels of intervention satisfaction at post-test. Finally, TGF indirectly decreased internalising and externalising problems at follow-up through improvements in perseverance reported at post-test. CONCLUSIONS: TGF offers a universal, 'add-on' mindset intervention complementing usual care programmes. It improves mindsets, perseverance and mental health in youth with ID. Both practical and theoretical implications are discussed.

'You are Okay': Effects of a support and educational program for children with mild intellectual disability and their parents with mental health concerns.

BACKGROUND: Children with mild intellectual disabilities and emotional and behavioural problems whose parents have mental health concerns are at an increased risk of developing problems themselves. This study analysed the effectiveness of the 'You are Okay'-program aimed to support these children and parents and to reduce the risk of problem development in children. METHOD: A quasi-experimental design was used to compare the experimental group ('care as usual' and 'You are Okay') with the control group ('care as usual') on the main outcome of emotional and behavioural problems and proposed intermediate outcomes. RESULTS: Children in the experimental group reported a significant medium to large decrease in emotional and behavioural problems compared to the control group. The effects on the intermediate outcomes were non-significant. CONCLUSIONS: This specific study population comprising a vulnerable group of children seems to benefit from this specially adapted 'You are Okay'-program. More research is necessary to draw further conclusions.

Social-emotional problems of children with mild intellectual disabilities having parents with mental health concerns: A quantitative comparison study.

INTRODUCTION: Children of parents with mental health concerns are at-risk for social-emotional problems. In this study, we assessed whether children with a mild intellectual disability and parents with mental health concerns are particularly at-risk. METHOD: Strengths and Difficulties Questionnaire (SDQ) reports of children with a mild intellectual disability (N = 55) and their parents with mental health concerns (N = 45) were compared to two comparison groups. The first group included children with average intelligence (N = 13) and their parents with mental health concerns (N = 56), the second group included children with mild intellectual disability (N = 44) and their parents (N = 36). RESULTS: Children with a mild intellectual disability and a parent with mental health concerns show higher total SDQ problem scores and more internalizing and externalizing problems as compared to children in the two other groups. DISCUSSION: Children having mild intellectual disability and parents with mental health concerns are particularly at risk for developing social-emotional problems.

Are patients accurate forecasters of their emotional response to medical conditions? A scoping review on affective forecasting.

OBJECTIVE: In this paper, we challenge the premise that patients are capable of accurately predicting their emotional response or quality of life in anticipation of health changes. Our goal was to systematically review the published empirical evidence related to the reliability of affective forecasting in the context of medical conditions. DESIGN: Scoping review. SETTING: We conducted a search string using both simple search terms as well as MeSH terms and searched the electronic databases of PubMed, Embase, CINAHL and Cochrane up to April 2021. PARTICIPANTS: We initially selected 5726 articles. Empirical studies reporting on predicted and/or observed emotions or quality of life concerning deterioration, improvement in health or chronic illnesses were included. Furthermore, empirical studies of healthy individuals predicting emotional response or quality of life compared with patients reflecting on emotions or quality of life concerning deterioration or improvement in health or chronic illnesses were also included. Studies on healthy participants, psychiatric patients and non-English articles were excluded. RESULTS: 7 articles were included in this review. We found that patients generally tend to systematically exaggerate both anticipated happiness and sorrow/grief after health improvement and deterioration, respectively. CONCLUSION: Patients are less adept in predicting emotional response or quality of life regarding to health changes than we are inclined to assume. We discuss several biases which could explain this phenomenon. Our findings are relevant in the context of treatment decisions, advanced care planning and advanced care directives.

Factors facilitating or hindering meaningful staff-client interactions in people with intellectual disabilities and challenging behaviour: A systematic mixed studies review using thematic synthesis.

BACKGROUND: Interactions with professional caregivers affect the quality of support and life of people with intellectual disabilities and contribute to the occurrence of challenging behaviour. The present literature review provides an overview of factors facilitating or hindering meaningful staff-client interactions in people with borderline to profound intellectual disabilities and challenging behaviour. METHOD: Database searches, reference list and citation screening, and expert consultations were undertaken. A thematic synthesis of 28 studies was performed. RESULTS: Factors were identified at the client (i.e. behaviour, emotions and (dis)abilities), staff (i.e. interactive principles, knowledge, psychological resources, attributions, attitudes and (coping with) emotions) and context levels (i.e. group size, team and organization). CONCLUSIONS: The present overview provides insights into factors that facilitate or hinder meaningful staff-client interactions with people with intellectual disabilities and challenging behaviour. The results support the need to combine client, staff and contextual factors when considering staff-client interactions in research and practice.

Hemithyroidectomy versus total thyroidectomy for well differentiated T1-2 N0 thyroid cancer: systematic review and meta-analysis.

BACKGROUND: Evidence for limiting the extent of surgery in patients with low-risk thyroid cancer is lacking. METHODS: A systematic search was performed according to the PRISMA and MOOSE guidelines to assess the effect of total thyroidectomy (TT) with or without radioactive iodine (RAI) treatment versus hemithyroidectomy (HT) on recurrence and overall mortality in patients with differentiated (papillary or follicular) T1-2 N0 thyroid cancer. PubMed, Embase and Cochrane databases were searched, and two authors independently assessed the articles. RESULTS: A total of ten eligible articles were identified. All were observational cohort series, representing a total of 23 134 patients, of which 17 699 were available for meta-analysis. Six studies included patients who had TT followed by RAI treatment. The pooled recurrence rate after TT ± RAI and HT was 2·3 and 2·8 per cent respectively (odds ratio (OR) 1·12, 95 per cent c.i. 0·82 to 1·53; P = 0·48). The pooled 20-year overall survival rate after TT ± RAI was 96·8 per cent, compared with 97·4 per cent for HT (OR 1·30, 0·71 to 2·37; P = 0·40). Overall, higher complication rates were found in the TT ± RAI group. CONCLUSION: Recurrence rates after HT for treatment of well differentiated T1-2 N0 thyroid cancer were similar to those after TT ± RAI, with a lower incidence of treatment-related complications.

ANTECEDENTES: No hay evidencia para limitar la extensión de la cirugía en pacientes con cáncer de tiroides de bajo riesgo. MÉTODOS: Se realizó una búsqueda sistemática siguiendo las recomendaciones PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) y MOOSE (Meta-analysis of Observational Studies in Epidemiology) para evaluar el efecto de la tiroidectomía total (TT) +/− yodo radioactivo (radioactive iodine treatment, RAI) versus hemitiroidectomía (HT) en la recidiva y en la mortalidad global en el cáncer de tiroides diferenciado (papilar/folicular) T1-T2N0. Se realizaron búsquedas en las bases de datos PubMed, Embase y Cochrane, y dos autores evaluaron los artículos de forma independiente. RESULTADOS: Se identificaron un total de 10 artículos de interés. Todos ellos eran estudios de cohortes observacionales, con un total de 23.134 pacientes, de los cuales 17.699 se incluyeron en el metaanálisis. En seis estudios, los pacientes fueron tratados mediante TT seguida de RAI. Las tasas agrupadas de recidiva tras TT +/− RAI y HT fueron 2,3% and 2,8%, respectivamente (razón de oportunidades, odds ratio, OR = 1,12, i.c. del 95% 0,82-1,54, P = 0.48). La supervivencia global a 20 años de TT +/− RAI fue del 96,8% en comparación con el 97,4% para la HT (OR = 1,30, i.c. del 95% 0,71-2,37, P = 0,40). Globalmente, se observaron más complicaciones en el grupo de TT +/− RAI. CONCLUSIÓN: Esta revisión sistemática con metaanálisis demuestra tasas de recidiva similares tras una HT para el tratamiento del cáncer de tiroides T1-2N0 bien diferenciado en comparación con TT +/− RAI, con una menor incidencia de complicaciones relacionadas con el tratamiento.

The association between allergic diseases and cancer: a systematic review of the literature.

INTRODUCTION: Atopic syndrome (allergic rhinitis, asthma and eczema) and food allergies are frequently reported, especially in developed countries. Studies have previously suggested an inverse association between allergic diseases and cancer. The aim of this study was to investigate the association between allergic diseases and different types of cancers by performing a systematic review of the literature. METHODS: A systematic literature search of Ovid Medline, Embase, Web of Science, Cochrane Library and Google Scholar was performed for studies on the association between allergic diseases and cancers. RESULTS: We identified a total of 5868 articles through our search, with 145 articles describing an association between allergic diseases and cancers. Allergies were associated with reduced risk of brain cancer, pancreatic cancer and melanoma and with possibly reduced risk of lymphatic and hematopoietic cancer, colorectal cancer, urogenital cancers of women and cancers in general. Asthma, but not atopy without asthma, was however associated with increased risk of lung cancer. There is possibly no association between allergic diseases and the risk of breast cancer and prostate cancer. CONCLUSION: Overall, allergic diseases are inversely associated with the risk of cancers.

Allergic acute coronary syndrome in exercise-induced anaphylaxis.

In this case report we present a 49-year-old male who was seen in the emergency department after collapsing due to anaphylactic shock, with ECG findings suggesting myocardial ischaemia. We linked both diagnoses to Kounis syndrome, which describes an acute coronary syndrome due to an allergic event. His circulatory collapse was explained by exercise-induced anaphylaxis.

Nonsteroidal anti-inflammatory drug hypersensitivity: not always an allergy!

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a major cause of hypersensitivity reactions. Several distinct clinical syndromes are described regarding NSAID hypersensitivity. Such a reaction is generally caused by a non-immunological mechanism. In susceptible patients, COX-1 inhibition leads to an imbalance in lipid mediators such as leukotrienes and prostaglandins. It is essential to distinguish multiple nonspecific NSAID hypersensitivity from single NSAID hypersensitivity, since the management of these respective syndromes is essentially different. This review provides an overview on all the aspects of NSAID hypersensitivity reactions, from pathophysiology to clinical symptoms, leading practical recommendations.

[Sleep-wake patterns in adults with autism spectrum disorders in a clinical setting: a pilot study]. / Slaap-waakstoornissen bij volwassenen met autisme in een klinische setting: een pilotstudie.

BACKGROUND: The negative consequences of sleep-wake disorders in the general population and in children with an autism spectrum disorder (ASD) are well-established. However, little is known about sleep-wake disorders in adults with ASD.
AIM: To study and measure sleep-wake disorders and sleep-wake patterns in adults in a clinical facility who have been diagnosed primarily as having ASD without any comorbid intellectual disability.
METHOD: We assessed the sleep patterns of 19 patients in a residential facility. We asked patients to provide their sleep history, answer questionnaires and keep a sleep diary (subjective measurement). We also asked patients to collect actigraphy data (objective measurement) for seven days and to provide information about comorbid symptoms of anxiety and depression and use of medication.
RESULTS: Nine patients (47%) had undiagnosed comorbid sleep-wake disorders. Patients in our study overrated their sleep efficiency (diary) compared to objective data (actigraphy). However, patients' subjective sleep quality did match patients' sleep efficiency. Only two out of 14 patients with symptoms of anxiety and/or depression were diagnosed with a comorbid depressive disorder, 15 patients were treated with medication.
CONCLUSION: Sleep-wake disorders and comorbid symptoms of anxiety and depression might be more prevalent in adults with ASD in a residential facility than reported so far. This possibility needs to be considered more carefully during the diagnostic process and during treatment.

Beck's cognitive theory and the response style theory of depression in adolescents with and without mild to borderline intellectual disability.

AIM: This study tests the validity of Beck's cognitive theory and Nolen-Hoeksema's response style theory of depression in adolescents with and without MBID. METHODS: The relationship between negative cognitive errors (Beck), response styles (Nolen-Hoeksema) and depressive symptoms was examined in 135 adolescents using linear regression. RESULTS: The cognitive error 'underestimation of the ability to cope' was more prevalent among adolescents with MBID than among adolescents with average intelligence. This was the only negative cognitive error that predicted depressive symptoms. There were no differences between groups in the prevalence of the three response styles. In line with the theory, ruminating was positively and problem-solving was negatively related to depressive symptoms. Distractive response styles were not related to depressive symptoms. The relationship between response styles, cognitive errors and depressive symptoms were similar for both groups. CONCLUSION: The main premises of both theories of depression are equally applicable to adolescents with and without MBID. The cognitive error 'Underestimation of the ability to cope' poses a specific risk factor for developing a depression for adolescents with MBID and requires special attention in treatment and prevention of depression. WHAT THIS PAPER ADDS?: Despite the high prevalence of depression among adolescents with MBID, little is known about the etiology and cognitive processes that play a role in the development of depression in this group. The current paper fills this gap in research by examining the core tenets of two important theories on the etiology of depression (Beck's cognitive theory and Nolen-Hoeksema's response style theory) in a clinical sample of adolescents with and without MBID. This paper demonstrated that the theories are equally applicable to adolescents with MBID, as to adolescents with average intellectual ability. However, the cognitive bias 'underestimation of the ability to cope' was the only cognitive error related to depressive symptoms, and was much more prevalent among adolescents with MBID than among adolescents with average intellectual ability. This suggests that underestimating one's coping skills may be a unique risk factor for depression among adolescents with MBID. This knowledge is important in understanding the causes and perpetuating mechanisms of depression in adolescents with MBID, and for the development of prevention- and treatment programs for adolescents with MBID.

Cognitive functioning of individuals aged 90 years and older without dementia: A systematic review.

INTRODUCTION: Reference values to define cognitive impairment in individuals aged 90 years and older are lacking. We systematically reviewed the literature to determine the level of cognitive functioning of individuals aged 90 years and older without dementia. METHODS: The search identified 3972 articles of which 20 articles were included in the review. We calculated mean cognitive test scores and cut-off scores for cognitive tests published in two or more articles. RESULTS: The mean cognitive test scores (SD)/cut-off scores for individuals aged 90 years and older without dementia of the five most commonly used cognitive tests were: MMSE: 26.6 (2.6)/23.3 points, Digit Span forward: 5.9 (1.8)/3.6 digits, Digit Span backward: 4.4 (1.6)/2.4 digits, TMT-A: 85.8 (42.5)/140.2s and TMT-B: 220.3 (99.2)/347.3s. DISCUSSION: We provided mean cognitive test scores and cut-off scores that will improve the diagnostic process of cognitive impairment in individuals aged 90 years and older.

Kinase dynamics. Using ancient protein kinases to unravel a modern cancer drug's mechanism.

Macromolecular function is rooted in energy landscapes, where sequence determines not a single structure but an ensemble of conformations. Hence, evolution modifies a protein's function by altering its energy landscape. Here, we recreate the evolutionary pathway between two modern human oncogenes, Src and Abl, by reconstructing their common ancestors. Our evolutionary reconstruction combined with x-ray structures of the common ancestor and pre-steady-state kinetics reveals a detailed atomistic mechanism for selectivity of the successful cancer drug Gleevec. Gleevec affinity is gained during the evolutionary trajectory toward Abl and lost toward Src, primarily by shifting an induced-fit equilibrium that is also disrupted in the clinical T315I resistance mutation. This work reveals the mechanism of Gleevec specificity while offering insights into how energy landscapes evolve.

Internet programs targeting multiple lifestyle interventions in primary and secondary care are not superior to usual care alone in improving cardiovascular risk profile: a systematic review.

OBJECTIVE: To review the effects of Internet delivered multiple modifiable lifestyle interventions complementary to usual care on cardiovascular risk factors in the primary and secondary healthcare setting. METHOD: PubMed, EMBASE.com, CINAHL, PsycINFO, and the Cochrane Library were searched up to June 2012 for English written studies that 1) addressed multiple lifestyle interventions, 2) used Internet intervention through websites or email, 3) included at least one usual care group not using Internet, 4) aimed to improve any of cardiovascular risk factors and 5) targeted patients aged 18 or older. RESULTS: Our systematic search yielded 1857 citations of which 9 were selected for this review. Three studies reported significant differences in weight loss in favor of the intervention group and five studies reported non-significant differences between groups. From the 7 studies reporting on blood pressure (BP) measurements, two found significant improvement in favor of the intervention group, while the other studies found no significant differences. Only one study found a significant improvement of LDL-C in the intervention group compared to usual care. Another study found a significant improvement of HDL-C in the usual care group compared to the intervention group. CONCLUSION: The addition of a multiple modifiable lifestyle Internet intervention in primary or secondary care is not superior to usual care with respect to prevention and treatment of cardiovascular risk factors. However, an Internet delivered program does have the potential of being successful in reducing the number of doctor's visits and may therefore be cost-effective when applied in large scale.

Texture and shape of two-dimensional domains of nematic liquid crystals.

We present a generalized approach to compute the shape and internal structure of two-dimensional nematic domains. By using conformal mappings, we are able to compute the director field for a given domain shape that we choose from a rich class, which includes drops with large and small aspect ratios and sharp domain tips as well as smooth ones. Results are assembled in a phase diagram that for given domain size, surface tension, anchoring strength, and elastic constant shows the transitions from a homogeneous to a bipolar director field, from circular to elongated droplets, and from sharp to smooth domain tips. We find a previously unaccounted for regime, where the drop is nearly circular, the director field bipolar, and the tip rounded. We also find that bicircular director fields, with foci that lie outside the domain, provide a remarkably accurate description of the optimal director field for a large range of values of the various shape parameters.

Magnetic field effects on tactoids of plate-like colloids.

We investigate the effect of a magnetic field on the shape and director field of nematic droplets in dispersions of sterically stabilized and charge-stabilized colloidal gibbsite platelets with a negative diamagnetic anisotropy. Depending on the magnetic field strength and tactoid size, we observe with polarized light microscopy several interesting structures, with different shapes and director fields both with and without defects. In particular, our findings provide the first experimental evidence for the existence of the split-core defect structure predicted ten years ago by Mkaddem and Gartland [Phys. Rev. E 62, 6694 (2000)]. The split-core structure is a metastable director-field configuration that can be stabilized by a sufficiently strong externally applied magnetic field but only if the diamagnetic anisotropy of the particles is negative. To account for our observations, we present a calculation of the stability regions of different shapes and director-field structures as a function of tactoid size, anchoring conditions, surface tension, elastic constants, and magnetic field strength. By fitting the experimental data to the theoretically predicted structures, we are able to extract values for the splay elastic constant, interfacial tension, and anchoring strength. Remarkably, we find significant differences between the two systems studied: for sterically stabilized gibbsite in bromotoluene the anchoring strength is one order of magnitude larger than that of aqueous gibbsite, with the latter exhibiting weak and the former strong anchoring of the director field to the interface. The splay elastic constants that we obtain are in agreement with earlier experiments, simulations, and theory, while the interfacial tension and anchoring strength are considerably larger than what was found in earlier experiments.

Tactoids of plate-like particles: size, shape, and director field.

We studied, by means of polarized light microscopy, the shape and director field of nematic tactoids as a function of their size in dispersions of colloidal gibbsite platelets in polar and apolar solvents. Because of the homeotropic anchoring of the platelets to the interface, we found large tactoids to be spherical with a radial director field, whereas small tactoids turn out to have an oblate shape and a homogeneous director field, in accordance with theoretical predictions. The transition from a radial to a homogeneous director field seems to proceed via two different routes depending in our case on the solvent. In one route, the what presumably is a hedgehog point defect in the center of the tactoid transforms into a ring defect with a radius that presumably goes to infinity with decreasing drop size. In the other route, the hedgehog defect is displaced from the center to the edge of the tactoid, where it becomes virtual again going to infinity with decreasing drop size. Furthermore, quantitative analysis of the tactoid properties provides us with useful information on the ratio of the splay elastic constant and the anchoring strength and the ratio of the anchoring strength and the surface tension.

Depressive mood and smoking onset: A comparison of adolescents with and without asthma.

This prospective population-based study aimed to compare associations between depressive feelings and smoking behaviour of adolescents with and without asthma. Data were collected from a two-wave 22-24 months prospective study among 5938 adolescents who completed self-report questionnaires. Logistic regression analyses showed that depressive feelings and smoking were related both cross-sectionally and longitudinally. Smoking behaviour was similar for adolescents with and without asthma, as well as its correlation with depressive feelings. However, participants with asthma were more likely to report depressive feelings than those without asthma, implying an indirect relationship between asthma and smoking behaviour. Implications for prevention are addressed.
