Is neurodevelopment impaired in Brazilian children with intestinal failure on prolonged parenteral nutrition? A single center study.

Purpose: To assess the neurodevelopment outcomes of children younger than 42 months of age with intestinal failure (IF) using prolonged parenteral nutrition (PN) followed by a Pediatric Multidisciplinary Intestinal Rehabilitation Program from a public tertiary hospital in Brazil.

Methods: Bayley III scale was administered in children aged 2 to 42 months with IF and receiving PN for more than 60 days. Composite scores in cognitive, motor, and language domains were analyzed.

Self-reported social media use by adolescents in Brazil: a school-based survey.

Objective: Although there is a general perception that adolescent social media use is a global phenomenon, there is a scarcity of data on patterns and preferences of social media use among youth in low- and middle-income countries (LMICs). We here describe self-reported prevalence and perceived effects of social media use in a school-based sample of Brazilian adolescents.

Methods: We analyzed cross-sectional data on 7,113 adolescents aged 14 to 16 years enrolled at 101 public state schools between 2018 and 2019 in Porto Alegre, state of Rio Grande do Sul, Brazil.

Aspiration in the First Year of Life and Later Tube Feeding: A Retrospective Cohort from a Low-Income Country.

The objective of this study is to investigate in infants submitted to videofluoroscopic swallowing study (VFSS) during the first year of life, the association between aspiration and later tube feeding, and to identify potential risk factors related to feeding route outcome. Retrospective cohort study with data from electronic health records was performed. Data were collected from infants < 12 months of age who underwent VFSS during inpatient hospital stay in the period between 2013 and 2018.

Influence of intra- and extrauterine factors on infant sleep in the first 6 months of life.

Objective: Infant sleep problems can affect the child's health. Maternal characteristics have been associated with the quality of infant sleep, but few studies have investigated the impact of intrauterine conditions. The aim of the study was to evaluate the association between adverse intrauterine environments (maternal smoking, hypertension, diabetes, and intrauterine growth restriction) and extrauterine factors on infant sleep in the first 6 months of life.

Intrinsic Brain Connectivity Following Long-Term Treatment with Methylphenidate in Children with Attention-Deficit/Hyperactivity Disorder.

Introduction: Although widely used for the treatment of attention-deficit/hyperactivity disorder (ADHD) across the life span, the effects of methylphenidate (MPH) on the brain are not completely understood. Functional neuroimaging techniques may help increase knowledge about the mechanisms of MPH action.

Objective: To evaluate changes in functional connectivity patterns of the default mode network (DMN) in children with ADHD following long-term treatment with MPH.

Searching for the best approach to assess teachers' perception of inattention and hyperactivity problems at school.

Although major guidelines in the field and current diagnostic criteria clearly demand an assessment of children's attention deficit/hyperactivity disorder (ADHD) symptoms at school, few studies address the fundamental question of which is the best approach for clinicians to get this information from teachers. Three screening strategies for ADHD were applied to teachers of 247 third grade students. They were asked (1) an overt question about potential cases of ADHD in their classroom; (2) to complete a broad-band questionnaire assessing common child mental health problems; (3) to rate ADHD-specific symptoms in a narrow-band questionnaire.

Bilateral perisylvian ulegyria: an under-recognized, surgically remediable epileptic syndrome.

Purpose: Interest in the association of epilepsy and pseudobulbar palsy was rekindled since the identification through magnetic resonance imaging (MRI) of bilateral perisylvian polymicrogyria (PMG). Seizures are often intractable, but resective epilepsy surgery has not been recommended. However, a similar clinical picture can be encountered in patients with bilateral perisylvian destructive lesions, which fit the description of ulegyria (ULG).

Increasing teachers' knowledge about ADHD and learning disorders: an investigation on the role of a psychoeducational intervention.

Objective: To investigate elementary school teachers' baseline knowledge about ADHD and learning disorders (LD) and the impact of a strategy to increase awareness of these disorders.

Method: A total of 37 teachers were selected from four elementary schools in the catchment area of the University Hospital, in Porto Alegre, Brazil. To evaluate teachers' knowledge, two self-report questionnaires about ADHD and LD were applied before and after an awareness program on these disorders.

ADHD in children and adults: diagnosis and prognosis.

Attention-deficit hyperactivity disorder (ADHD) is one of the most common neuropsychiatric disorders with childhood onset, having a chronic course associated with high dysfunction and morbidity throughout life. Despite significant advances in our understanding of the neurobiological underpinnings of the disorder, diagnosis of ADHD remains strictly clinical and is based on behavioral symptoms of inattention, impulsivity, and hyperactivity. In this chapter, we review the diagnostic process and current controversies in the diagnosis of ADHD, discuss the clinical presentation of the disorder across the lifespan, and examine the patterns of comorbidity and the longitudinal predictors of outcomes.

Mental disorders and delivery motorcycle drivers (motoboys): a dangerous association.

Objective: Low and middle-income countries experience an expressive growth in the number of circulating motorcycles, paralleled by an increasing number of traffic accidents. Delivery motorcycles drivers ("motoboys") are generally perceived as accountable for this scenario. Although traffic accidents have a multivariate etiology, mental disorders, such as substance use disorders (SUD) and attention deficit/hyperactivity disorder (ADHD), are often involved.
