Abstract
Suicide is a serious public health problem and is among the top ten causes of death worldwide for all age groups. It is the third leading cause among 15-35-year olds. The main objective of this quasi-experimental, quantitative, and cross-sectional study was to compare the levels of suicidal ideation among college students (n = 50) and nonstudents (n = 51). Subjects were compared according to sex, age, place of residence, living arrangements, educational level, and occupational status using the Suicidal Ideation Questionnaire. The sample consisted of 101 individuals aged 18- 25 years, Mean of 21.44 years and Standard Deviation of 2.43. The results showed higher levels of suicidal ideation among the non-college students. Statistically significant effects were found among the following variables: level of education, occupational status, living alone, and presence of anxiety disorder and/or depression. The findings of this study suggest the need for suicide prevention measures in order to reduce deaths by suicide and suicide attempt rate.

Abstract
There still are many clinical and biological aspects of the natural history of cancer of the upper aerodigestive tract to be unveiled; which in Brazil is a direct consequence of the failure of systematic prevention and early diagnosis campaigns. Objective: To analyze the signs and symptoms presented by patients with the disease at initial and advanced stages. Other variables such as disease duration, general and nutritional status were considered. Method: A historical cohort study with a cross-section involving 895 subjects with cancer of the upper aerodigestive tract. Results: Clinical findings were not statistically correlated with disease progression, nor with the disease in early stages, but it showed rapid disease development. Conclusion: The results suggest a disease of insidious onset in the early stages and fast course afterwards. The long disease duration - greater than three months, was associated with worsening in general and nutritional states of patients.

Abstract
The present study aims to translate and validate the Temple Presence Inventory (TPI) for the Portuguese context, respecting the maintenance of an equivalent semantics as well as the validity of its contents and concepts. This study also aims to verify the psychometric properties of the instrument (factor validity and internal consistency). The sample consisted of 455 individuals (male = 271, female = 184). The fidelity of the factors varied between 0.5 and 0.84. The confirmatory factor analysis produced a theoretical model with 38 items distributed among eight factors. The covariance between some residual errors of instrument items was considered, and the following fit indices were observed: chi 2/df = 2.073; GFI = 0.858; CFI = 0.887; RSMEA = 0.049; AIC = 1527. The results confirm the appropriateness of the version adapted to the Portuguese language of the TPI and that it can be used in research projects aiming to evaluate Presence in the Portuguese-speaking population (Europe).

Abstract
This article analyzes the use of physical education in treating mental illness by describing the contributions of this area to mental health therapies. Based on several studies, the authors discuss the benefits of physical education as a therapeutic aid in reducing the symptoms of psychic disorders. The conclusion is that physical education and science can be useful to psychiatry as part of interdisciplinary efforts in the treatment of patients with mental distress.

Abstract
The purpose of the present study was to assess the factor structure and reliability of the Depression, Anxiety and Stress Scales (DASS-21) in a large Portuguese community sample. Participants were 1020 adults (585 women and 435 men), with a mean age of 36.74 (SD = 11.90) years. All scales revealed good reliability, with Cronbach's alpha values between .80 (anxiety) and .84 (depression). The internal consistency of the total score was .92. Confirmatory factor analysis revealed that the best-fitting model (*CFI = .940, *RMSEA = .038) consisted of a latent component of general psychological distress (or negative affectivity) plus orthogonal depression, anxiety and stress factors. The Portuguese version of the DASS-21 showed good psychometric properties (factorial validity and reliability) and thus can be used as a reliable and valid instrument for measuring depression, anxiety and stress symptoms.
