RESUMO
OBJECTIVE: To identify predictive factors for the length of physiotherapy sessions for adult intensive care unit (ICU) patients. DESIGN: Longitudinal panel study. SETTING: ICU of a secondary-care public teaching hospital, the University Hospital at the University of Sao Paulo, Brazil. PARTICIPANTS: Medical and surgical patients who received physiotherapy (N=181) assessed in 339 physiotherapy sessions. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The study investigator followed physiotherapists during their work shift and timed the physiotherapy session's length with a stopwatch. The association between session length and patient, physiotherapist, and service-related factors was evaluated by a mixed model. RESULTS: Assessed in this study were 339 physiotherapy sessions during 79 periods of observation that involved 181 patients and 19 physiotherapists. Median session length was 29 (interquartile range: 22.6-38.9) minutes; median number of patients assisted per physiotherapist per 6-hour shift was 5 (4-5). Physiotherapist's median age was 35 (26-39) years old, and median ICU experience was 13.0 (0.4-16.0) years. Patients were mostly older adults who were post surgery and had been at the ICU for 5 (2-9) days. Factors associated with physiotherapy session length (min) were the following: performing both motor- and respiratory-related physiotherapy procedures during the session (ß=6.5; 95% confidence interval [CI], 3.8-9.2), altered chest x-ray (ß=2.8; 95% CI, 0.3-5.3), ICU mobility scale (IMS) (ß=1.2; 95% CI, 0.4-2.0), contraindication to any level of out-of-bed mobilization (ß=-6.9; 95% CI, -10.5 to -3.3), afternoon shift (ß=-4.0; 95% CI, -6.7 to -1.4), and Barthel index (ß=-0.2; 95% CI, -0.3 to -0.1). CONCLUSIONS: The factors associated with longer session lengths were performing both motor- and respiratory-related physiotherapy procedures during the session, altered chest x-ray, and the IMS. Contraindication to any level of out-of-bed mobilization and sessions performed during the afternoon shift (vs the morning shift) were associated with shorter session lengths.

BACKGROUND: Web-based personalized normative feedback (PNF) interventions are less effective than their laboratory versions. Participant motivation may account for this reduced effect, but there is only a limited amount of research into the influence of motivation on PNF effectiveness. We evaluated the effectiveness of a web-based PNF in reducing alcohol use and consequences among college students with different motivation levels. METHODS: Pragmatic randomized controlled trial among Brazilian college drinkers aged 18-30 years (N = 4460). Participants were randomized to a Control or PNF group and followed-up after one (T1), three (T2) and six (T3) months. Outcomes were: AUDIT score (primary outcome), the number of consequences, and the typical number of drinks. Motivation for receiving the intervention was assessed with a visual analog scale (range: 0-10). Generalized mixed models assessed intervention effects via two paradigms: observed cases and attrition models. RESULTS: PNF reduced the number of typical drinks at T1 (OR = 0.71, p = 0.002), T2 (OR = 0.60, p < 0.001) and T3 (OR = 0.68, p = 0.016), compared to the control. Motivated students (score ≥3) receiving PNF also reduced the number of typical drinks at T1 (OR = 0.60, p < 0.001), T2 (OR = 0.55, p < 0.001) and T3 (OR = 0.56, p = 0.001), compared to the control. However, the attrition models were more robust at T1 and T2. In contrast, low-motivated students receiving the PNF increased AUDIT score at T3 (b = 1.49, p < 0.001). CONCLUSIONS: The intervention reduced alcohol use, and motivation for receiving the intervention moderated the intervention effects. Motivated students reduced their typical alcohol use, whereas low-motivated students increased their AUDIT score.

This study aimed to compare answers given by parents and their adolescent children to the Portuguese version of the Parent Mealtime Action Scale (PMAS) and to assess associations among the reported behaviors. To compare these answers, a cross-sectional study was conducted in a sample of 72 patients of the Obesity Clinic of the Division of Nutrology of the Pediatrics Department at the Federal University of São Paulo (Unifesp), Brazil. These patients were aged from 10 years to 19 years and 11 months, and their parents or legal guardians also participated. First, parents were interviewed and instructed to answer how often they perform each behavior measured by the PMAS (never, sometimes or always). Next, the same questions were answered by the adolescents. The general linear model (GLM) showed the effects of the interviewees and of the interaction between interviewees and sex. We also observed a triple interaction effect (sex x interviewees x categorized age). The internal reliability of the PMAS was higher for parental answers than for those given by the children. This finding is probably observed because the scale has been developed and validated to evaluate the pattern of parental responses concerning their eating practices during their children's meals. In addition, although parents believe they are engaging in certain behaviors, the effectiveness of these strategies may not be recognized by their children. Very low intraclass correlation coefficients were observed between parents' and children's answers to the original domains of the PMAS (ICC: 0.130-0.578), suggesting that the factorial structure of the PMAS may only be used to assess parental behavior, as it is not sufficiently accurate to assess the children's understanding of parent mealtime actions.

Attention-deficit/hyperactivity disorder (ADHD) is a widely studied neurodevelopmental disorder. It is a highly heterogeneous condition, encompassing different types of expression. The predominantly inattentive type is the most prevalent and the most stable over the lifetime, yet it is the least-studied presentation. To increase understanding of its cognitive profile, 29 children with attention-deficit/hyperactivity disorder of predominantly inattentive type (ADHD-I) and 29 matched controls, aged 7-15 years, had their attentional abilities assessed through the Conners' continuous performance test. Diffusion tensor imaging data were collected for all of the participants using a 3.0-T MRI system. Fractional anisotropy (FA) values were obtained for 20 fiber tracts, and brain-behavior correlations were calculated for 42 of the children. The ADHD-I children differed significantly from the typically developing (TD) children with respect to attentional measures, such as the ability to maintain response-time consistency throughout the task (Hit RT SE and Variability), vigilance (Hit RT ISI and Hit RT ISI SE), processing speed (Hit RT), selective attention (Omissions), sustained attention (Hit RT Block Change), error profile (Response Style), and inhibitory control (Perseverations). Evidence of significant differences between the ADHD-I and the TD participants was not found with respect to the mean FA values in the fiber tracts analyzed. Moderate and strong correlations between performance on the attention indicators and the tract-average FA values were found for the ADHD-I group. Our results contribute to a better characterization of the attentional profile of ADHD-I individuals and suggest that in children and adolescents with ADHD-I, attentional performance is mainly associated with the white matter structure of the long associative fibers that connect anterior-posterior brain areas.
RESUMO
Slow wave oscillations in the electroencephalogram (EEG) during sleep may reflect both sleep need and intensity, which are implied in homeostatic regulation. Adenosine is strongly implicated in sleep homeostasis, and a single nucleotide polymorphism in the adenosine deaminase gene (ADA G22A) has been associated with deeper and more efficient sleep. The present study verified the association between the ADA G22A polymorphism and changes in sleep EEG spectral power (from C3-A2, C4-A1, O1-A2, and O2-A1 derivations) in the Epidemiologic Sleep Study (EPISONO) sample from São Paulo, Brazil. Eight-hundred individuals were subjected to full-night polysomnography and ADA G22A genotyping. Spectral analysis of the EEG was carried out in all individuals using fast Fourier transformation of the signals from each EEG electrode. The genotype groups were compared in the whole sample and in a subsample of 120 individuals matched according to ADA genotype for age, gender, body mass index, caffeine intake status, presence of sleep disturbance, and sleep-disturbing medication. When compared with homozygous GG genotype carriers, A allele carriers showed higher delta spectral power in Stage 1 and Stages 3+4 of sleep, and increased theta spectral power in Stages 1, 2 and REM sleep. These changes were seen both in the whole sample and in the matched subset. The higher EEG spectral power indicates that the sleep of individuals carrying the A allele may be more intense. Therefore, this polymorphism may be an important source of variation in sleep homeostasis in humans, through modulation of specific components of the sleep EEG.

The goal of the present study was to compare the relative distress of homosexual and heterosexual Brazilian men and women on scenarios in which they imagined their partners sexually or emotionally involved with another person, using a forced-choice paradigm and continuous measures. Participants were 68 heterosexual men, 72 heterosexual women, 42 homosexual men, and 35 homosexual women. On the forced-choice questions heterosexual men (39 on one question and 37 on the other) were more upset than their female counterparts (21 on one question and 15 on the other) by scenarios of sexual infidelity than those of emotional infidelity. On questions using continuous measures no significant difference was found between pleasurable sex and attachment scenarios for heterosexual women or heterosexual men. On the highly upsetting scenarios heterosexual men discriminated between flirting and both pleasurable sex and attachment scenarios, being less disturbed by the former. In contrast, heterosexual women were equally distressed by the three scenarios. Scores for the homosexual men and homosexual women fell in between those of the heterosexual men and heterosexual women and did not show a clear cut preference for the sexual infidelity or the emotional alternative on the forced-choice paradigm. However, on the continuous measures of jealousy homosexuals resembled heterosexuals of the opposite sex. There was no evidence that jealousy would be less intense among homosexuals although reproductive outcomes were not at risk.

The present study investigated the contribution of men's facial hair to impression formation. Participants evaluated photographs of one of four versions of a man--clean shaven, mustached, goateed, or bearded--on a 7-point scale. In Study 1, participants were 106 Brazilian undergraduates (68 men and 38 women). Beardedness was associated with older age, greater responsibility, and leftist political ideas. In Study 2, respondents were 50 Brazilian personnel managers (28 men and 22 women) who made hiring decisions at different companies in the city of Saõ Paulo. Personnel managers clearly preferred clean shaven over bearded, mustached, or goateed men as prospective employees. In a hiring situation for a conservative occupation, a man who signals disposition to conform to rules may be preferred by personnel managers over another who signals nonconformity.
