    Associations between oral health-related quality of life and emotional statuses in children and preadolescents
    (Wiley-Blackwell, 2012-10-01) Barbosa, T. S.; Castelo, P. M. [UNIFESP]; Leme, M. S.; Gaviao, M. B. D.; Universidade Estadual de Campinas (UNICAMP); Universidade Federal de São Paulo (UNIFESP)
    Oral Diseases (2012) 18, 639647 Objectives: To evaluate the associations between oral health-related quality of life (OHRQoL) and emotional statuses in children and preadolescents. Methods: One hundred and forty-five Brazilian students (814 years) were clinically examined for caries, gingivitis, fluorosis, malocclusions, and temporomandibular disorders (TMD). OHRQoL was measured using two global ratings of oral health (OH) and overall well-being (OWB). the Revised Childrens Manifest Anxiety Scale (R-CMAS) and Childrens Depression Inventory (CDI) were used to assess anxiety and depression, respectively. SalivCezannea was collected 30 min after waking and at night to determine the diurnal decline in salivary cortisol (DDSC). the results were analyzed using non-paired t test/one-way ANOVA, Pearsons correlation test, and multiple linear regression analyses. Results: 1114-year-old participants had higher CDI scores (P < 0.01) and DDSC concentrations (P < 0.001). Participants with fewer caries and without gingivitis had higher DDSC concentrations (P < 0.05). TMD patients had higher DDSC concentrations and OWB ratings (P < 0.001). Girls had higher Revised Childrens Manifest Anxiety Scale (RCMAS) scores (P < 0.01). There was positive correlation between RCMAS and CDI scores and OWB ratings (P < 0.05). the OH model retained age (beta =0.312; P < 0.001) and the OWB model retained TMD (beta = 0.271; P < 0.001) and CDI scores (beta=0.175; P < 0.05). Conclusions: Children and preadolescents with poor emotional well-being are more sensitive to the impacts of OH and its effects on OWB.

    Effects of Mindfulness-Based Interventions on Salivary Cortisol in Healthy Adults: A Meta-Analytical Review
    (Frontiers Media Sa, 2016) Sanada, Kenji; Montero-Marin, Jesus; Alda Diez, Marta; Salas-Valero, Montserrat; Perez-Yus, Maria C.; Morillo, Hector; Demarzo, Marcelo Marcos Piva [UNIFESP]; Garcia-Toro, Mauro; Garcia-Campayo, Javier
    Objective: The aim of the present study was to elucidate the effects of Mindfulness-based interventions (MBIs) on salivary cortisol levels in healthy adult populations. Method: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs), published between January 1980 and June 2015 in PubMed, EMBASE, PsycINFO and the Cochrane library. The PRISMA and Cochrane guidelines were followed. The pooled effect sizes were calculated with the random-effects model, using Hedges' g-values, and heterogeneity was measured using the 12 statistic. The contribution of different characteristics of participants and programmes were assessed by meta-regression models, using beta coefficients. Results: Five RCTs with 190 participants in total were included in this systematic review. The overall effect size (ES) for improving the state of health related to cortisol levels was moderately low (g = 0.41

    Repetitive transcranial magnetic stimulation reduces cortisol concentrations in bulimic disorders
    (Cambridge Univ Press, 2011-06-01) Claudino, A. M. [UNIFESP]; Van den Eynde, F.; Stahl, D.; Dew, T.; Andiappan, M.; Kalthoff, J.; Schmidt, U.; Campbell, I. C.; Kings Coll London; Universidade Federal de São Paulo (UNIFESP); Kings Coll NHS Trust
    Background. in people with bulimic eating disorders, exposure to high-calorie foods can result in increases in food craving, raised subjective stress and salivary cortisol concentrations. This cue-induced food craving can be reduced by repetitive transcranial magnetic stimulation (rTMS). We investigated whether rTMS has a similar effect on salivary cortisol concentrations, a measure of hypothalamic-pituitary-adrenal axis (HPAA) activity.Method. We enrolled twenty-two female participants who took part in a double-blind randomized sham-controlled trial on the effects of rTMS on food craving. Per group, eleven participants were randomized to the real or sham rTMS condition. the intervention consisted of one session of high-frequency rTMS delivered to the left dorsolateral prefrontal cortex (DLPFC). Salivary cortisol concentrations were assessed at four time points throughout the 90-min trial. To investigate differences in post-rTMS concentrations between the real and sham rTMS groups, a random-effects model including the pre-rTMS cortisol concentrations as covariates was used.Results. Salivary cortisol concentrations following real rTMS were significantly lower compared with those following sham rTMS. in this sample, there was also a trend for real rTMS to reduce food craving more than sham rTMS.Conclusions. These results suggest that rTMS applied to the left DLPFC alters HPAA activity in people with a bulimic disorder.
