Validity of Cognitive Disengagement Syndrome with Mother and Father Ratings of Brazilian Children: Replication of Northern Hemisphere Findings in South America.

Although the Child and Adolescent Behavior Inventory (CABI) cognitive disengagement syndrome (CDS) scale has demonstrated validity relative to the CABI attention-deficit/hyperactivity disorder-inattention (ADHD-IN) scale with parent ratings of youth from North America, Europe, East Asia, and Central Asia, no study has evaluated the validity of the 15 symptom CDS scale with children from South America. Our purpose was to examine for the first time the validity of the CABI CDS scale with Brazilian children. Latent variable modeling procedures were used to examine the validity of CDS scores.

Nonsurgical periodontal therapy decreases the severity of rheumatoid arthritis and the plasmatic and salivary levels of RANKL and Survivin: a short-term clinical study.

Aim: To investigate the influence of nonsurgical periodontal treatment (NSPT) on clinical periodontal status, rheumatoid arthritis (RA) activity, and plasmatic and salivary levels of biomarkers through a controlled clinical trial on individuals with RA and periodontitis (PE).

Methods: Sixty-six individuals from a convenience sample were considered eligible and consecutively allocated in 3 groups: (1) individuals without PE and RA (-PE-RA, n = 19); (2) individuals without PE and with RA (-PE+RA, n = 23), and (3) individuals with PE and RA (+PE+RA, n = 24). Full-mouth periodontal clinical examinations, Disease Activity Score (DAS-28) evaluations, and analysis in plasma and saliva of RANKL, OPG, RANKL/OPG, and Survivin were performed at baseline (T1) and 45 days after NSPT (T2).

Are neutrophil extracellular traps the link for the cross-talk between periodontitis and rheumatoid arthritis physiopathology?

Objectives: Neutrophil extracellular traps (NETs) play a role in the pathogenesis of periodontitis and rheumatoid arthritis (RA). However, it remains poorly understood whether NETs participate in the cross-talk between periodontitis and RA. Herein, we investigated the production of NETs in individuals with periodontitis and RA and its association with clinical parameters.

Clinical and microbiological effects of non-surgical periodontal treatment in individuals with rheumatoid arthritis: a controlled clinical trial.

The effect of periodontal treatment on clinical, microbiological and serological parameters of patients with rheumatoid arthritis (RA) are scarce and controversial. The aim of this study was to investigate the influence of non-surgical periodontal treatment on clinical periodontal status, subgingival bacterial levels of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and RA activity through a controlled clinical trial on individuals with RA and periodontitis (PE). From a convenience sample, 107 individuals were considered eligible and consecutively allocated in four groups: (1) individuals without PE and RA (- PE-RA, n = 30); (2) individuals without PE and with RA (- PE + RA, n = 23); (3) individuals with PE and RA (+ PE + RA, n = 24); and (4) individuals with PE and without RA (+ PE-RA, n = 30).

Association Between Sense of Coherence and Periodontal Outcomes: A Systematic Review and Meta-analysis.

This systematic review and meta-analysis aimed to evaluate the association between sense of coherence (SOC) and periodontal outcomes. Electronic searches were performed in 6 databases. Seventeen studies that evaluated the association between SOC and periodontal outcomes were included.

Periodontitis and Endothelial Dysfunction: Periodontal Clinical Parameters and Levels of Salivary Markers Interleukin-1β, Tumor Necrosis Factor-α, Matrix Metalloproteinase-2, Tissue Inhibitor of Metalloproteinases-2 Complex, and Nitric Oxide.

Background: Periodontitis has been associated with a greater risk for atherosclerotic cardiovascular disease (ACD). Endothelial dysfunction (ED) is a parameter of early ACD, and its association with periodontitis has rarely been investigated to date. The objective of this study is to evaluate the association between periodontitis and ED by means of periodontal clinical parameters and salivary markers interleukin (IL)-1β, tumor necrosis factor (TNF)-α, nitric oxide (NO), and matrix metalloproteinase (MMP)-2 and tissue inhibitor of metalloproteinases (TIMP)-2 complex.

Bifactor latent structure of ADHD/ODD symptoms: predictions of dual-pathway/trait-impulsivity etiological models of ADHD.

Objective: To determine if ADHD/ODD symptoms are better represented by a bifactor model of disruptive behavior [general disruptive behavior factor along with specific inattention (IN), specific hyperactivity/impulsivity (HI), and specific oppositional defiant disorder (ODD) factors] than an ADHD-IN, ADHD-HI, and ODD three-factor model.

Method: Mothers' and fathers' ratings of ADHD-IN, ADHD-HI, and ODD symptoms in a community sample of 4,658 children and adolescents (53% female) from Brazil, Thailand, and the US were used to evaluate the measurement models.

Results: The bifactor model of disruptive behavior provided a better fit than the three factor model.

Oppositional defiant behavior toward adults and oppositional defiant behavior toward other children: evidence for two separate constructs with mothers' and fathers' ratings of Brazilian children.

Background: Confirmatory factor analysis (CFA) was used to determine if oppositional defiant behavior (ODB) toward adults and oppositional defiant behavior toward other children were constructs distinct from each other as well as from attention-deficit/hyperactivity disorder-hyperactivity/impulsivity (ADHD-HI), attention-deficit/hyperactivity disorder-inattention (ADHD-IN), and academic competence.

Methods: Mothers and fathers rated the occurrence of the DSM-IV oppositional defiant disorder (ODD) symptoms where the target was an adult (e.g.

Invariance and convergent and discriminant validity between mothers' and fathers' ratings of oppositional defiant disorder toward adults, ADHD-HI, ADHD-IN, and academic competence factors within Brazilian, Thai, and American children.

Confirmatory factor analysis was used to test the invariance of an oppositional defiant disorder toward adults, attention-deficit/hyperactivity disorder-hyperactivity/impulsivity, attention-deficit/hyperactivity disorder-inattention, and an Academic Competence factor model between mothers' and fathers' ratings within Brazilian (n = 894), Thai (n = 2,075), and American (n = 817) children with the Child and Adolescent Disruptive Behavior Inventory (G. L. Burns, T.

Understanding source effects in ADHD rating scales: reply to DuPaul (2003).

G. J. DuPaul (2003) offered two suggestions for additional research to understand the strong source effects reported by R.

A multitrait-multisource confirmatory factor analytic approach to the construct validity of ADHD rating scales.

Confirmatory factor analysis was used to model a multitrait-multisource design to evaluate the construct validity of attention-deficit/hyperactivity disorder (ADHD) rating scales. The 2 trait factors were the ADHD inattention and hyperactivity/impulsivity dimensions. The 2 source factors were parents and teachers.
