A systematic review of observational, naturalistic, and neurophysiological outcome measures of nonpharmacological interventions for autism

Objective: Naturalistic and neurophysiological assessments are relevant as outcome measures in autism intervention trials because they provide, respectively, ecologically valid information about functioning and underlying neurocognitive mechanisms. We conducted a systematic review to highlight which specific neurophysiological techniques, experimental tasks, and naturalistic protocols have been used to assess neural and behavioral functioning in autism intervention studies. Methods: Studies were collected from four electronic databases between October 2019 and February 2020: MEDLINE (via PubMed), PsycINFO, LILACS, and Web of Science, and were included if they used structured observational, naturalistic, or neurophysiological measures to assess the efficacy of a nonpharmacological intervention for ASD. Results: Fourteen different measures were used by 64 studies, with the Autism Diagnostic Observation Schedule the most frequently used instrument. Thirty-seven different coding systems of naturalistic measures were used across 51 studies, most of which used different protocols. Twenty-four neurophysiological measures were used in 16 studies, with different experimental paradigms and neurophysiological components used across studies. Conclusions: Cross-study variability in assessing the outcomes of autism interventions may obscure comparisons and conclusions about how different behavioral interventions affect autistic social communication and underlying neurophysiological mechanisms.

Preserved executive functioning and low stress symptoms in children treated for acute lymphoblastic leukemia.

Pediatric cancer treatment can negatively impact cognitive and psychosocial development, although it has been suggested that these adverse effects may be minimized when children have higher resilience and better executive functioning. We aimed to evaluate the impact of pediatric Acute Lymphoblastic Leukemia (ALL) treatment on executive function, resilience and stress in survivors and to investigate correlations between executive functioning and resilience and between executive functioning and stress. The neuropsychological assessment was performed in 32 ALL survivors aged 7-17 years and 28 age-, sex- and socioeconomic status matched controls. Executive functioning was assessed by inhibitory control, mental flexibility and working memory tasks. Children's self-report scales were used to assess stress symptoms and resilience. Results revealed no executive function impairment nor stress symptom differences between ALL survivors and control group. In the ALL group, executive function and resilience were positively correlated, whereas executive function and stress were negatively correlated. We concluded that ALL treatment was not associated with impairment in executive functioning nor to increased stress symptoms in our sample. ALL survivors with better performance in mental flexibility and inhibition tasks reported fewer stress symptoms and more resilience, indicating a possible relationship between these variables.

Assessment of Executive Functions after Treatment of Childhood Acute Lymphoid Leukemia: a Systematic Review.

Individuals treated for childhood acute lymphoblastic leukemia (ALL) have a high survival rate. This fact, however, may lead to neurocognitive impairments in survivors, as shown in some studies. The prefrontal cortex and executive functions seem to be particularly vulnerable due to the late maturation in the development process. Executive impairments have been associated with poorer quality of life in childhood cancer survivors. A systematic review was carried out with studies that assessed executive functions in childhood ALL survivors.\ Studies were collected from five electronic databases: MEDLINE (PubMed); PsycInfo; WebOfScience; LILACS and IBECS. Eighty-four studies were retrieved from the database search, of which 50 were read in full and 26 met the inclusion criteria. The studies were heterogeneous as to the instruments used to assess executive function, the skills assessed and the comparison methods. Despite some discrepancies, ALL survivors seem to exhibit poorer executive functioning than typical controls, but this result did not hold true when subjects were compared to normative mean. Changes in brain structure and dynamics resulting from the disease itself, the toxicity of the treatment and difficulties in coping with the stress during treatment may be related to executive impairments in ALL survivors. Discussion proposed standardized methods and measures for assessing executive functioning in children during and after ALL treatment.

Investigação da ansiedade, depressão e qualidade de vida em pacientes portadores de osteoartrite no joelho: um estudo comparativo / Investigation of depression, anxiety and quality of life in patients with knee osteoarthritis: a comparative study

RESUMOIntrodução:A osteoartrite (OA), artrose ou osteoartrose acomete a cartilagem hialina e o osso subcondral e compromete a articulação como um todo. A articulação do joelho caracteriza-se como um dos principais sítios de acometimento da OA. O envelhecimento, o sobrepeso e o gênero (prevalência em mulheres) são os fatores de risco mais significativos para o desenvolvimento da doença. A OA é considerada uma das mais frequentes causas de incapacidade laborativa e pode afetar a qualidade de vida de seus portadores e favorecer a emergência de transtornos mentais.Objetivo:Avaliar se os sintomas de ansiedade e depressão são mais expressivos em mulheres com OA quando comparados com mulheres sem tal diagnóstico e o quanto essa doença reumática compromete a qualidade de vida desses pacientes.Métodos:Participaram deste estudo 75 mulheres, com média de 67 anos, 40 com diagnóstico de OA no joelho e 35 sem. Foram usados os seguintes instrumentos: Inventário de Ansiedade Traço e Estado, Inventário de Depressão de Beck e SF-36, questionário de qualidade de vida.Resultados:Mulheres portadoras de OA no joelho têm níveis maiores de depressão e ansiedade, além de apresentar qualidade de vida inferior em comparação com o grupo sem a doença.Conclusão:Acreditamos que o tratamento aos portadores de OA deveria considerar a combinação de farmacoterapia, psicoterapia, orientação e apoio por parte dos parentes e/ou pessoas próximas para que o paciente possa atingir melhor qualidade de vida.

ABSTRACTIntroduction:Osteoarthritis (OA) affects the articular cartilage and subchondral bone, compromising the joint as a whole. The knee joint is characterized as one of the main sites of involvement of OA and the most significant risk factors for developing the disease are aging, overweight and female gender. OA is considered one of the most frequent causes of disability, which may affect the quality of life of the patients, favoring the onset of mental disorders.Objective:To investigate whether anxiety and depression symptoms are more significant in women with OA, when compared with women without this diagnosis, and to what extent this rheumatic disease affects the quality of life of these patients.Methods:The study included 75 women, mean age 67 years; 40 were diagnosed with knee OA and 35 without this diagnosis. The following instruments were used: State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI) and SF-36, a quality of life questionnaire.Results:Women with knee OA have higher rates of depression and anxiety when compared to controls; in addition, they have a lower quality of life.Conclusion:We believe that the treatment of patients with OA should consider the combination of pharmacotherapy, psychotherapy, counseling and family support, in order to achieve a better quality of life.
