Consistency and reliability of the Brazilian Portuguese version of the Mini-Sleep Questionnaire in undergraduate students

PurposeQuestionnaires are indispensable tools in epidemiologic studies and clinical surveys. Many questionnaires focusing on sleep disorders have been described in the literature. This cross-sectional study is aimed to assess the consistency and reliability of the Brazilian Portuguese Version of the Mini-Sleep Questionnaire (MSQ-BR).MethodsSelf-administered questionnaires were given to a sample of 1,108 undergraduate students. The variables collected were age, gender, socioeconomic level, and MSQ-BR scores. A subgroup of 53 students was randomly chosen to test the test–retest reliability of the instrument. Internal consistency of total MSQ-BR and its subscales (i.e., insomnia and hypersomnia) was evaluated using Cronbach’s alpha coefficient.ResultsOur results showed good internal consistency of total MSQ-BR score, with a Cronbach’s alpha value of 0.770. The insomnia subscale had an adequate internal consistency (Cronbach’s alpha, 0.749). On the other hand, the hypersomnia subscale had moderate internal consistency (Cronbach’s alpha, 0.624). The test–retest analysis showed good reliability of the instrument using Pearson’s correlation coefficient.ConclusionsThe MSQ-BR has adequate internal consistency and test–retest reliability. The MSQ-BR insomnia has adequate internal consistency for use as a separate application. However, the MSQ-BR hypersomnia demonstrated only moderate internal consistency for use as a separate application. Our intention was not to introduce modifications to the questionnaire, but to evaluate the reliability of total MSQ-BR and its subscales. Others studies are needed to assess the consistency of MSQ compared to other instruments.

Sleep disorders among undergraduate students in Southern Brazil

PurposeSleep disorders are very common in the young, being a result of the typical lifestyle lived by young people or a sleep disease that requires assistance and treatment. Furthermore, according to previous findings, sleep alterations can favor the development of depressive mood disorder. This survey aimed to assess the prevalence and characteristics of sleep disorders in a young population sample and their association with depressive symptoms.MethodsWith a cross-sectional study design, self-administered questionnaires were applied to 1,180 undergraduate students. The Mini-Sleep Questionnaire (MSQ) and the Beck Depression Inventory were used to evaluate sleep disturbances and depressive symptoms, respectively. Bivariate and multivariate analyses were conducted, with the main findings being the presence of disrupted sleep (MSQ > 24), with an alpha error of 5%. The median point of the MSQ was 26 (P25–P75, 21–32 points).ResultsSleep alterations were found in 59.6%. The prevalence of depression was 9.3% (n = 110), mild depression being identified in 5.9% (n = 62), moderate in 3.4% (n = 40), and severe in 0.7% (n = 8) of the students. In logistic regression, female gender (OR, 1.48; CI 95%, 1.09–2.01; P = 0.012) and being depressed (OR, 4.42; CI 95%, 2.30–8.50; P < 0.001) were independent factors for disrupted sleep.ConclusionsSleep alterations are prevalent complaints among young people, being present in nearly 60% of the students. Female gender and being depressed are independent factors for having some form of sleep disorder.

Association between primary headaches and depression in young adults in southern Brazil

OBJECTIVE To verify the association between depression and headache in young adults, as well as to identify the features of headache associated with depression and the influence of this mood disorder on headache-related disability. METHODS A cross-sectional study with self-administered questionnaires about headache and depression was conducted at the Universidade de Caxias do Sul. Beck Depression Inventory (BDI) and Migraine Disability Assessment (MIDAS) were used to evaluate depressive symptoms and headache-related disability, respectively. Depression was considered if BDI ≥ 15. RESULTS A thousand and thirteen young adults were included in the study. A clear relationship was observed between headache and depression among the participants. Multivariate analyses demonstrated that nausea or vomiting related to headache and higher headache-related disability scores were independent factors associated with depression. Migraine was more associated with depression than the other types of headache. CONCLUSION The results demonstrate an association between headache and depression. Depressive symptoms are more likely to be found in young adults with more disabling headaches.

Staging of colorectal cancer in the private service versus Brazilian National Public Health System: what has changed after five years?

INTRODUCTION: Cancer is a disease that affects a large population, being the colorectal cancer one of the most prevalent. The early diagnosis of these neoplasms represents a better life expectancy. The high cost of diagnostic tests and the low socioeconomic status are considered factors leading to delayed diagnosis. OBJECTIVES: Assess the difference between colorectal cancer staging in patients of private clinics and patients of the Brazilian National Health Service (SUS) and assess the changes in cancer staging in the past five years. METHODS: This retrospective study was conducted with 53 patients divided in two groups (SUS and private clinic) diagnosed with colorectal cancer and treated in 2009. Staging of patients diagnosed in 2009 was compared with data from patients diagnosed in 2004, already published in 2005. RESULTS: Both groups were similar in gender and age. Regarding the staging of patients, no statistical difference was observed between the two groups (p=0.147). When comparing the staging of patients diagnosed in 2009 with that of patients studied in 2004, patients diagnosed in 2009 presented early stages (II and III) in relation to patients analyzed in 2004 (III and IV), p<0.001. CONCLUSION: No significant difference was observed in cancer staging between SUS and private clinic patients. The patients analyzed in 2009 were diagnosed with early stage tumors when compared to patients diagnosed in 2004.

Fungus ball of the paranasal sinuses: report of two cases and literature review

Summary Introduction: Fungal ball of the sinuses is a not invasive infection that if characterizes for its chronicity, being the majority related with previous endodontic treatment. Affect mainly the breasts to maxillary; even so all the breasts can be involved. The main etiological agent is the Aspergillus spp. The computed tomography, had to characteristic the radiological presentations, suggests the diagnosis that is carried through definitively through histopathological analyses. The treatment standard-gold is the sinus surgery with average meatal antrostomy. Objective: Reporting two cases of fungal ball of the sinuses and to stand out important aspects of this pathology. Story of the Cases: Case 1) Patient of the feminine sex, 78 years old, presented itself with complaints of face pain has 6 months and previous history of endodontic treatment. To the physical examination it was evidenced purulent secretion presence in left average meatus. Ray X presented complete veiling of the breasts to maxillary left, while the computed tomography showed injury calcified in this place. Sinusotomy was become fulfilled that evolved well. Case 2) Patient of the feminine sex, 70 years old, looked attendance for history of sinusitis of repetition. To the physical examination no particularity was not perceived. The computed tomography, as well as the magnetic resonance, detected thickening of the mucous wall of the breasts to maxillary left, beyond a calcified mass. It was become fulfilled same sequence of treatment and the patient also evolved well. Final Considerations: The fungal infection must be considered in the patients who if present with chronic sinusitis, that they do not answer to the antibiotic use and that they possess history of endodontic manipulation.

Biocompatibility Assessment of Poly(lactic acid) Films after Sterilization with Ethylene Oxide in Histological Study In Vivo with Wistar Rats and Cellular Adhesion of Fibroblasts In Vitro

Biomaterials must meet certain fundamental requirements for their usage in living beings, such as biocompatibility, bifunctionality, and sterilizability, without having chemical and structural changes. The biocompatibility of poly(lactic acid) (PLA) films, shaped by compression, was evaluated after sterilization by ethylene oxide by a histological in vivo test with Wistar rats and cytotoxicity in cell adhesion in vitro. The cytotoxicity test was performed by the reduction of tetrazolium salt (MTT). Thermal and chemical changes in PLA films concerning the proposed sterilization process and characteristics were not observed to evidence polymer degradation due to sterilization. The analysis of the cytotoxicity by the MTT method has shown that the sterilized PLA films are not cytotoxic. The adhesion and proliferation of fibroblasts on PLA films were homogeneously distributed over the evaluation period, showing an elongated appearance with unnumbered cytoplasmic extensions and cell-cell interactions. By examining the biocompatibility in a histological study, a mild tissue inflammation was observed with the presence of fibrosis in the samples that had been exposed for 21 days in the rats’ bodies. PLA films sterilized with ethylene oxide did not exhibit cell adhesion in vitro and toxicity to the surrounding tissue in vivo and they may be used in future in vivo testing, according to histological findings in Wistar rats in the present study.
