Effects of academic stress on the levels of oral volatile sulfur compounds, halitosis-related bacteria and stress biomarkers of healthy female undergraduate students.

To investigate whether academic stress changes the salivary microbiota and its relationship with salivary parameters, evaluating the effects on the production of volatile sulfur compounds (VSCs) in healthy women. Fifty-five women who were enrolled in a four-year Dentistry course were assessed for academic stress by the questionnaire Maslach Burnout Inventory-Student Survey and were then classified into 'Not Stressed' and 'Stressed' groups. Cortisol and alpha-amylase (AA) were measured as physiological stress biomarkers.

Prevalence and correlates of common mental disorders among dental students in Brazil.

This study aimed to estimate prevalence of common mental disorders (CMD) and associated factors among dental students. In this cross-sectional study, 230 students answered a questionnaire and instruments to assess CMD (Self Reporting Questionnaire-20), hazardous alcohol consumption (Alcohol Use Disorder Identification Test), social support (Social Support Scale), perceptions of academic life (Dundee Ready Education Environment Measure), coping (Ways of Coping Inventory) and resilience (Resilience Scale). Bivariate analysis was conducted using the Chi-Square and Mann-Whitney tests.

Stress-related salivary proteins affect the production of volatile sulfur compounds by oral bacteria.

Objective: To determine whether stress-related substances and sex hormones influence the growth and in vitro production of volatile sulfur compounds (VSCs) by Solobacterium moorei and Fusobacterium nucleatum.

Materials And Methods: Bacteria growth and VSCs production were evaluated in the presence of alpha-amylase, beta-defensin-2, mucin, estradiol, and progesterone. Growth was evaluated by colony counting, and the production of the VSCs hydrogen sulfide (H S) and methyl mercaptan (CH SH) was measured using the Oral Chroma™ instrument.

Changes in salivary microbiota increase volatile sulfur compounds production in healthy male subjects with academic-related chronic stress.

Objective: To investigate the associations among salivary bacteria, oral emanations of volatile sulfur compounds, and academic-related chronic stress in healthy male subjects.

Materials And Methods: Seventy-eight healthy male undergraduate dental students were classified as stressed or not by evaluation of burnout, a syndrome attributed to academic-related chronic stress. This evaluation was carried out using the Maslach Burnout Inventory-Student Survey questionnaire.

[Collaboration and participation of children in speech therapy care].

Situations of non-cooperation/participation of the patient are detected in healthcare,. In many cases, it is impossible to complete the assessment procedures, and procedures of intervention may be prejudiced. This problem has been researched in some health areas, however there are few studies involving activities in Speech Therapy.

[Determinants of the exclusive breastfeeding abandonment in children assisted by interdisciplinary program on breast feeding promotion].

Objectives: To identify variables potentially related with the exclusive breastfeeding abandonment in children assisted by interdisciplinary program on breast feeding promotion.

Methods: Data were collected by a longitudinal study with 111 mothers who breastfeed their children until six months of age. Univariate analyses were used to assess factors associated with the exclusive breastfeeding abandonment, and also multiple regression analyses.

[The impact of breastfeeding promotion in women with formal employment].

This study focused on programs to promote breastfeeding in order to prevent early weaning of working mothers' infant children. A non-randomized intervention study was conducted using a survey of mothers who had returned to work after childbirth, including both participants and non-participants in a program to promote breastfeeding. The sample consisted of 200 mothers of infants ranging from 6 to 10 months of age.

Consequences of bottle-feeding to the oral facial development of initially breastfed children.

Objective: To identify and assess the possible consequences of bottle-feeding on the oral facial development of children who were breastfed up to at least six months of age.

Method: Two hundred and two children (4 years of age) enrolled in an early health attention program participated in the study. The sample was divided into two groups: G1 (children who used only a cup to drink) and G2 (those who used a bottle).
