Comorbidades físicas e psicológicas antes e depois da cirurgia bariátrica : um estudo longitudinal
Introduction: Morbid obesity has multiple implications for
psychological and physical health. Bariatric surgery has been
selected as the treatment of choice for this chronic disease,
despite the controversial impact of the surgery on psychosocial
health. The objective of this study was to describe candidates
for bariatric surgery and analyze changes in weight, psychopathology,
personality, and health problems and complaints at
6- and 12- month follow-up assessments.
Methods: Thirty obese patients (20 women and 10 men) with a
mean age of 39.17±8.81 years were evaluated in different dimensions
before surgery and 6 and 12 months after the procedure.
Results: Six and 12 months after bariatric surgery, patients
reported significant weight loss and a significant reduction in
the number of health problems and complaints. The rates of
self-reported psychopathology were low before surgery, and
there were no statistically significant changes over time. The
conscientiousness, extraversion, and agreeableness dimensions
increased, but neuroticism and openness remained unchanged.
All changes had a medium effect size.
Conclusions: Our results suggest that patients experience
significant health improvements and some positive personality
changes after bariatric surgery. Even though these findings
underscore the role of bariatric surgery as a relevant treatment
for morbid obesity, more in-depth longitudinal studies
are needed to elucidate the evolution of patients after the
procedure.Introdução: A obesidade mórbida tem várias implicações para
a saúde psicológica e física. A cirurgia bariátrica tem sido o
tratamento de escolha para essa doença crônica, apesar da
controvérsia sobre o impacto da cirurgia na saúde psicossocial.
O objetivo deste estudo foi descrever candidatos a cirurgia bariátrica e analisar mudanças no peso, psicopatologia personalidade,
problemas e queixas de saúde desses pacientes em avaliações
realizadas 6 e 12 meses após a cirurgia.
Métodos: Trinta pacientes obesos (20 mulheres e 10 homens)
com idade média de 39,17±8,81 anos foram avaliados em diferentes
dimensões antes da cirurgia e 6 e 12 meses após.
Resultados: Aos 6 e 12 meses após a cirurgia bariátrica, os
pacientes relataram significativa perda de peso e significativa
redução no número de problemas e queixas de saúde. As taxas
de psicopatologia autorrelatada foram baixas antes da cirurgia e
não sofreram mudanças significativas com o tempo. As dimensões
conscienciosidade, extroversão e agradabilidade aumentaram,
mas o neuroticismo e a abertura permaneceram inalteradas.
Todas as mudanças apresentaram um tamanho de efeito médio.
Conclusões: Os nossos resultados sugerem que os pacientes
experimentam melhoras significativas em saúde e algumas mudanças
positivas de personalidade após a cirurgia bariátrica.
Embora esses achados reforcem o papel da cirurgia bariátrica
como um tratamento relevante para a obesidade mórbida, mais
estudos longitudinais e aprofundados são necessários para elucidar
a evolução dos pacientes após a realização do procedimento.(undefined
Sensory theories of developmental dyslexia: three challenges for research.
Recent years have seen the publication of a range of new theories suggesting that the basis of dyslexia might be sensory dysfunction. In this Opinion article, the evidence for and against several prominent sensory theories of dyslexia is closely scrutinized. Contrary to the causal claims being made, my analysis suggests that many proposed sensory deficits might result from the effects of reduced reading experience on the dyslexic brain. I therefore suggest that longitudinal studies of sensory processing, beginning in infancy, are required to successfully identify the neural basis of developmental dyslexia. Such studies could have a powerful impact on remediation.This is the accepted manuscript. The final version is available from NPG at http://www.nature.com/nrn/journal/v16/n1/abs/nrn3836.html
