- Association between depression severity and executive functioning in late-life depression: a systematic reviewPublication . Monteiro, Suzana; Monteiro, Bárbara; Candida, Maristela; Adler, Nathalia; Campos, Carlos; Rocha, Nuno; Paes, Flávia; Nardi, Antônio Egidio; Machado, SérgioOBJECTIVE: Late-life depression is an under-diagnosed and under-treated disease that reduces the well-being of older adults. Executive dysfunction is another critical impairment in elderly depressed individuals which further disrupts their everyday functioning. This systematic review aims to analyze the association between executive function and depression severity in elderly individuals diagnosed with major depressive disorder. METHOD: The studies were retrieved from MEDLINE/PubMed, ISI Web of Knowledge and PsychInfo, after a search strategy combining the terms "depression", "executive function", "neuropsychological assessment", "elderly" and "late life". Study selection, data collection and quality ratings was performed by two independent raters. RESULTS: A total of 1,130 articles were found but only 8 studies met the defined eligibility criteria and evaluated the association between depression severity and executive functioning. Six out of 8 studies found an association between depression severity and executive function, with correlations ranging from small to large (r= -0.15 to -0.53). The included reports had several methodological limitations such as selective data reporting, non-comprehensive executive function assessment and not controlling potential biases. CONCLUSION: Depression severity may be more strongly correlated with a specific set of executive abilities although it also seems to be a broad-based association with executive functioning as a whole. Future high-quality prospective studies are recommended in order to understand the causal relationship between depression severity and executive functioning taking into account possible mediators such as age-related or neurodegenerative cognitive impairment, educational level and other clinic characteristics (e.g. age of onset, medication).
- Chronic effects of aerobic exercise on panic disorder: a systematic review of randomized and non-randomized trialsPublication . Lattari, Eduardo; Paes, Flávia; Machado, Ana; Rocha, Nuno Barbosa Ferreira; Nardi, Antônio Egidio; Machado, SérgioIn general, most studies have supported an association between the acute effects of exercise and a reduced state anxiety, but failed to completely explain the relationship between the chronic effect of exercise and anxiety traits. The aim of this study was to systematically review the literature regarding the chronic effect of exercise on symptoms associated with panic disorder. The studies were retrieved from a MEDLINE/PubMed, ISI Web of Knowledge and SciELO. We adopted PICOS’s strategy recommended to determine the eligibility criteria. The survey was conducted using an advanced search in the ISI Web of Science and MEDLINE / PubMed with MeSH terms and Entry Terms for the keywords “Panic Disorder” basis and “Exercise”. Boolean operators “AND” and “OR” were used separately or in combination. Two independent researchers performed the selection of studies; in case of disagreement they sought a consensus on the selection. A total of 265 articles were identified: 199 articles from PubMed/Medline, 63 articles from ISI Web of Science and 3 articles by manual searches. Thus, 31 articles were analyzed by the eligibility criteria and the exclusion criteria, a total of five studies included in the systematic review. The regular practice of aerobic exercise seems to be an appropriate intervention to promote improvements in the severity of anxiety symptoms in PD patients.
- Effects of dual-task interventions on gait performance of patients with Parkinson’s Disease: A systematic reviewPublication . Santos, Luís A. A.; Campos, Carlos; Bento, Teresa; Lattari, Eduardo; Nardi, Antônio Egidio; Rocha, Nuno; Machado, SérgioParkinson’s disease is characterized by motor and non-motor symptoms that impair patients’ gait performance, especially while performing dual/concurrent tasks. These deficits impair patients’ daily function, because dual-tasking is a crucial ability in terms of everyday living. The aim of this study was to systematically review the effects of dual task interventions on gait performance of patients with Parkinson’s disease. Studies were retrieved from MEDLINE/PubMed, LILACS and SciELO. We used the PICOS strategy to determine eligibility criteria. The search strategy included an advanced search on the included databases, using the following search query: “Parkinson’s Disease” AND “Double Task” OR “Concurrent Tasks” OR “Gait” AND “Walk”. Study selection was carried out by two independent researchers and a third one was called when consensus was needed. A total of 188 articles were identified: 169 articles from Medline/PubMed, 10 articles in SciELO, 8 articles in LILACS and 1 item from manual searches. A total of 56 articles were analyzed regarding the eligibility and exclusion criteria based on full text. A final total of 7 studies were included in the systematic review. The different types of dual-task interventions reported (dance, sound stimuli, visual and somatosensory) were associated to improvements in several gait performance indicators of Parkinson’s disease patients, including gait speed, stride time and length, cadence and step length. External stimuli seem to play a critical role on specific training effects on dual-task gait performance.
