Anxiety, Depression, and Anger in Bruxism: A Cross-sectional Study among Adult Attendees of a Preventive Center.

The relationship between emotional symptom and bruxism is not well-established. We aimed to investigate sleeping bruxism and psychological factors. A cross-sectional study was performed in working-age adults attended in general outpatient service. The main outcome was the sleep bruxism diagnosed by dentist. Sociodemographic, clinical and psychological characteristics were evaluated according to sleep bruxism (yes/no). Scores of self-report scales of psychological symptoms (Beck Anxiety Inventory, Patient Health Questionnaire, and Dimensions of Anger Reactions) were individually subjected to factor analysis, through the extraction method of principal axis factoring. The associations between probable cases of sleep bruxism with dimensions of anxiety (somatic and cognitive), depression, and anger were estimated by linear regression models. Linear regression models (with ß coefficients and 95% CI) were adjusted for sociodemographic covariates. Among 351 respondents, 37.3% presented sleep bruxism. Of them, high frequencies of symptoms of anger (68.1%), moderate-severe anxiety (23.6%), and depression (17.9%) were observed. After adjustment, somatic-anxiety (ß: 0,136; CI95%: 0,028 to 0.276) was associated with sleep bruxism, but not cognitive-anxiety, depression or anger. The presence of sleeping bruxism should be routinely explored among adults, regarding its relationship with emotional symptoms.

Dimensions of Anger Reactions (DAR-5): a useful screening tool for anger in the general population.

BACKGROUND: Dimensions of Anger Reactions (DAR-5) is a brief 5-item instrument to assess experience of anger. We aimed to verify the DAR-5 as a screening instrument in the community. METHODS: A sample of 368 apparently healthy adults who attended an outpatient ambulatory facility self-reported on the DAR-5 scale, the Spielberger's State-Trait Anger Expression Inventory (STAXI), the Beck Anxiety Inventory (BAI), and the Patient Health Questionnaire (PHQ-9). Indicators of reliability and validity were calculated to demonstrate the performance of the DAR-5. RESULTS: According to the DAR-5, around half the respondents found themselves becoming angry with people or situations and reported persistent duration of anger. Antagonism towards others was the least frequently experienced anger (8.4%). The DAR-5 was found to be reliable and stable, showing a significant correlation with the BAI and PHQ-9 for both sexes. In confirmatory factor analysis, a one-dimensional structure of anger experience was demonstrated through salient fit statistics. A cut-off > 8 was the best threshold against STAXI for discriminating cases of anger, irrespective of sex. CONCLUSIONS: The shortness of the DAR-5, along with its cost-effective applicability, qualifies this measuring tool as a useful instrument for inclusion in the routine assessment of anger reactions in the general population.Key pointsThis is the first time the validity of DAR-5 has been demonstrated in a developing country.The Portuguese version of DAR-5 has appropriate sensitivity and high specificity.The DAR-5 demonstrated to be a reliable and stable instrument, irrespective of sex.

Validating the Framingham Hypertension Risk Score: A 4-year follow-up from the Brazilian Longitudinal Study of the Adult Health (ELSA-Brasil).

The Framingham Heart Study published an equation that permits to estimate the 4-year incidence of hypertension among adults. In Brazil, only the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) of 15 105 men and women aged 35-74 years enrolled in 2008-2010 has data that can validate the Framingham Risk Score for Hypertension and create a new equation according to the Brazilian population. We examined the predictive performance of the Framingham Risk Score for Hypertension in the ELSA-Brasil using as an outcome variable, the 4-year incidence of hypertension. We split randomly the 8027 participants who participated in the second visit (2012-2014) and without hypertension at baseline in derivation data set (n = 4825; 60%) and a validation data set (n = 3202 participants; 40%). The area under the curve for Framingham Risk Score for Hypertension and ELSA-Brasil Risk Score was relatively similar. Hosmer-Lemeshow chi-squared statistic applied for the Framingham Risk Score was 3.78 (P-value = .876) and for our model was 8.22 (P-value = .41), disclosing good discrimination and calibration for both models. Even with these classification intervals, our model presents more underestimation of the risk, classifying 15% of the participants with new onset of hypertension in low risk vs 9% of the Framingham model and less overestimation of the risk, classifying 17% of the participants without hypertension as high risk vs 24% of the Framingham model. We concluded that the Framingham Risk Score for Hypertension has an acceptable performance when applied in the ELSA-Brasil population with good discrimination and calibration.

Anastomoses intestinais com histoacryl: comparacao entre anastomose com fio, com fio reforcada por histoacryl, com uso exclusivo de histoacryl: estudo experimental em ratos / Intestinal anastomosis performed with histoacryl: comparison between anastomosis performed with stitches, with stitches reinforced by histoacryl and exclusively with histoacryl

As anastomoses coloretais constituem controversia na literatura. A ocorrencia de deiscencia e fistula em varios estudos demonstrou a necessidade de pesquisa de novas tecnicas. Foram estudados 80 ratos em 4 tecnicas diferentes de anastomose e no quinto e setimo dias de pos-operatorio. A primeira tecnica foi executada com fio de sutura em 8 pontos separados...
