Association between bruxism, alcohol and tobaco use among brazilian students

The etiology of bruxism is not well defined. Different factors affecting the central nervous system are considered as risk factors for bruxism. Dental students are not immune to the bruxism, alcohol consumption and tobacco use, despite their training, knowledge of its effects and social responsibility. The purpose of this study was to evaluate the association between bruxism, alcohol consumption and tobacco use among Brazilian dental students. Participants were chosen among 180, 17-29 year-old students at the UNESP’s Dentistry School – Araçatuba Campus. They were divided into those with and without bruxism on the basis at validated clinical criteria. The clinical examinations were carried out by four standardized examiners (Intraexaminer and Interexaminer Unweighted kappa= 0.82, Weighted kappa= 0.89, respectively), in the clinic, with daylight and a tongue depressor. Bruxism was registered with the following categories: no wear facets, wear facets in enamel, dentine wear facets, facets wear half of the crown and wear facets more than 2/3 of the tooth crown. A self report validated questionnaire for alcohol consumption and tobacco use with 29 questions was completed by both groups. Fischer exact test and T-test were used and Odds Ratio and Confidence Interval was estimated. Bruxism was more frequent among cigarette smokers both in men (68.4%) and in women (56.8%). Among all respondents in this group, 82.6% reported that they would like to quit smoking and those who have tried previously to quit (76.4%) found it made them more stressed. Drinker was more frequent in the group with bruxism also (66.5% of the female and 73.5% of the male). 88.4% reported drinking alcohol because it “allows dealing with stress in an adequate way”. Results suggest a positive association between bruxism and alcohol consumption and tobacco use.

Subtle Cognitive Deficits in Adults With a Previous History of Sydenham's Chorea During Childhood

Objective. To evaluate the neuropsychological profile and health-related quality of life (HRQOL) of adults who had rheumatic fever (RF) during childhood with and without Sydenham's chorea (SC).Methods. Three groups of patients were assessed: adults who had RF with SC during childhood (SC group), adults who had RF without SC during childhood (RF group), and controls (CT group). A range of neuropsychological tests looked at several cognitive domains. HRQOL was measured through a Brazilian version of the Short Form 36 (SF-36) health survey.Results. Twenty patients were included in the SC group, 23 patients in the RF group, and 19 patients in the CT group. The 3 groups were homogeneous regarding sex (P = 0.078), age (P = 0.799), schooling (P = 0.600), socioeconomic status (P = 0.138), intelligence quotient (P = 0.329), and scores for anxiety (P = 0.156) and depression (P = 0.076). The SC group demonstrated inferior performance in tests that assessed attention (Digit Span Forward [ P = 0.005], Corsi Block Forward [ P = 0.014]), speeded information processing (Trail Making A [ P = 0.009], Symbol Search [ P = 0.042]), and executive functions and working memory (Corsi Block Backward [ P = 0.028]), and higher scores for attention deficit scale (P = 0.030) when compared with the RF and CT groups. They also showed a tendency toward lower scores in the physical aspects, vitality, emotional aspects, and mental health domains of the SF-36. The RF group had a lower score for the general health domain than the CT group (P = 0.030).Conclusion. Patients who had SC during childhood can exhibit inferior performance in tasks that evaluate attention, speeded information processing, executive functions, and working memory in adult life. Therefore, there is indirect evidence of the persistence of dysfunction in cerebral circuits involved with the basal ganglia. They also presented a worse self-evaluation in HRQOL that was not related to cognitive impairments.

Variability and resistance mutations in the hepatitis C virus NS3 protease in patients not treated with protease inhibitors

The goal of treatment of chronic hepatitis C is to achieve a sustained virological response, which is defined as exhibiting undetectable hepatitis C virus (HCV) RNA levels in serum following therapy for at least six months. However, the current treatment is only effective in 50% of patients infected with HCV genotype 1, the most prevalent genotype in Brazil. Inhibitors of the serine protease non-structural protein 3 (NS3) have therefore been developed to improve the responses of HCV-infected patients. However, the emergence of drug-resistant variants has been the major obstacle to therapeutic success. The goal of this study was to evaluate the presence of resistance mutations and genetic polymorphisms in the NS3 genomic region of HCV from 37 patients infected with HCV genotype 1 had not been treated with protease inhibitors. Plasma viral RNA was used to amplify and sequence the HCV NS3 gene. The results indicate that the catalytic triad is conserved. A large number of substitutions were observed in codons 153, 40 and 91; the resistant variants T54A, T54S, V55A, R155K and A156T were also detected. This study shows that resistance mutations and genetic polymorphisms are present in the NS3 region of HCV in patients who have not been treated with protease inhibitors, data that are important in determining the efficiency of this new class of drugs in Brazil.

Treatment seeking by individuals with obsessive-compulsive disorder from the British Psychiatric Morbidity Survey of 2000

Objective: For several reasons, many individuals with obsessive-compulsive disorder (OCD) do not seek treatment. However, data on treatment seeking from community samples are scant. This study analyzed service use by adults with OCD living in private households in Great Britain. Methods: Data from the British Survey of Psychiatric Morbidity of 2000, in which 8,580 individuals were surveyed, were analyzed. Service use was compared for those with OCD, with other neuroses, with different subtypes of OCD (only obsessions, only compulsions, or both), and with OCD and comorbid neuroses. Results: Persons with OCD (N=114) were more likely than persons with other neuroses (N=1,395) to be receiving treatment (40% compared with 23%, p<.001). However, those with OCD alone (N=38) were much less likely than those with OCD and a comorbid disorder to be in treatment (14% compared with 56%, p<.001). In the previous year, 9.4% of persons with OCD had seen a psychiatrist and 4.6% had seen a psychologist. Five percent were receiving cognitive-behavioral therapy, 2% were taking selective serotonin reuptake inhibitors, and 10% were taking tricyclics. Conclusions: Most persons with OCD were not in contact with a mental health professional, and apparently very few were receiving appropriate treatments. Very few persons with noncomorbid OCD were receiving treatment. Individuals with OCD who are in treatment may not be disclosing their obsessions and compulsions and may be discussing other emotional symptoms, leading to inappropriate treatment strategies. Public awareness of OCD symptoms should be raised, and primary care professionals should inquire about them with all patients who have depressive or anxiety disorders.

Ambulatory blood pressure monitoring in children with obstructive sleep apnea and primary snoring

Objective: To evaluate the systemic blood pressure (BP) during daytime and nighttime in children with sleep breathing disorders (SBD) and compare parameters of BP in children with diagnosis of obstructive sleep apnea syndrome (OSA) to those one with primary snoring (PS).Methods: Children, both genders, aged from 8 to 12 years, with symptoms of SBD realized an overnight polysomnography followed by a 24 h recording of ambulatory BP.Results: All subjects presented with a history of snoring 7 nights per week. Children who have apnea/hipoapnea index >= four or a apnea index >= one presented a mean BP of 93 +/- 7 mmHg and 85 +/- 9 mmHg diurnal and nocturnal respectively whereas children who have a apnea/hipoapnea < four or a apnea index < one presented 90 +/- 7 mmHg and 77 +/- 2 mmHg. Eight children out of fourteen, from OSA group, lost the physiologic nocturnal dipping of the blood pressure. Among OSA children 57% were considered non-dippers. Two (16%) have presented absence of nocturnal dipping among children with primary snoring. The possibility of OSA children loosing physiologic blood pressure dipping was 6.66 higher than the possibilities of patients from PS group.Discussion: Our results indicate that children with sleep apnea syndrome exhibit a higher 24 h blood pressure when compared with those of primary snoring in form of decreased degree of nocturnal dipping and increased levels of diastolic and mean blood pressure, according to previous studies in literature. OSA in children seems to be associated to the development of hypertension or other cardiovascular disease. (C) 2012 Elsevier B.V. All rights reserved.

Serum homocysteine and physical exercise in patients with Parkinson's disease

Background: Hyperhomocysteinemia is a major risk factor for cerebral and peripheral vascular diseases, as well as cortical and hippocampal injury, including an increased risk of dementia and cognitive impairment. Elevated serum homocysteine (Hcy) concentrations are common in patients with Parkinson's disease (PD) who have been treated with levodopa; however, physical exercises can help reduce Hcy concentrations. The aim of the present study was to compare serum Hcy levels in patients with PD who partook in regular physical exercises, sedentary PD patients, and healthy controls.Methods: Sixty individuals were enrolled in the present study across three groups: (i) 17 patients who did not partake of any type of exercise; (ii) 24 PD patients who exercised regularly; and (iii) 19 healthy individuals who did not exercise regularly. All participants were evaluated by Hoehn and Yahr scale, the Unified Parkinson's Disease Rating Scale (UPDRS) and Schwab and England scale (measure daily functionality). The serum levels of Hcy were analyzed by blood samples collected of each participant. An analysis of variance and a Tukey's post hoc test were applied to compare and to verify differences between groups. Pearson's correlation and stepwise multiple regression analyses were used to consider the association between several variables.Results: Mean plasma Hcy concentrations in individuals who exercised regularly were similar to those in the healthy controls and significantly lower than those in the group that did not exercise at all (P = 0.000). In addition, patients who did not exercise were receiving significantly higher doses of levodopa than those patients who exercised regularly (P = 0.001). A positive relationship between levodopa dose and Hcy concentrations (R(2) = 0.27; P = 0.03) was observed in patients who did not exercise, but not in those patients who exercised regularly (R(2) = 0.023; P = 0.15).Conclusions: The results of the present study suggest that, even with regular levodopa therapy, Hcy concentrations in PD patients who exercise regularly are significantly lower than in patients who do not exercise and are similar Hcy concentrations in healthy controls.

Ploidy, sex and crossing over in an evolutionary aging model

Nowadays, many forms of reproduction coexist in nature: Asexual, Sexual, apomictic and meiotic parthenogenesis, hermaphroditism and parasex. The mechanisms of their evolution and what made them successful reproductive alternatives are very challenging and debated questions. Here, using a simple evolutionary aging model, we give I possible scenario. By studying the performance of Populations where individuals may have diverse characteristics-different ploidies, sex with or without crossing over, as well as the absence of sex-we find all evolution sequence that may explain why there are actually two major or leading groups: Sexual and asexual. We also investigate the dependence of these characteristics on different conditions of fertility and deleterious mutations. Finally, if the primeval organisms oil Earth were, in fact, asexual individuals we conjecture that the sexual form of reproduction could have more easily been set and found its niche during a period of low-intensity mutations.

Desfazendo mitos para minimizar o preconceito sobre a sexualidade de pessoas com deficiências

Este texto aborda a presença de idéias preconceituosas sobre a sexualidade de pessoas com deficiência discorrendo, de modo critico e reflexivo, sobre diversos mitos, tais como: (1) pessoas com deficiência são assexuadas: não têm sentimentos, pensamentos e necessidades sexuais; (2) pessoas com deficiência são hiperssexuadas: seus desejos são incontroláveis e exacerbados; (3) pessoas com deficiência são pouco atraentes, indesejáveis e incapazes para manter um relacionamento amoroso e sexual; (4) pessoas com deficiência não conseguem usufruir o sexo normal e têm disfunções sexuais relacionadas ao desejo, à excitação e ao orgasmo; (5) a reprodução para pessoas com deficiência é sempre problemática porque são pessoas estéreis, geram filhos com deficiência ou não têm condições de cuidar deles. A crença nesses mitos revela um modo preconceituoso de compreender a sexualidade de pessoas com deficiência como sendo desviante a partir de padrões definidores de normalidade e isso se torna um obstáculo para a vida afetiva e sexual plena daqueles que são estigmatizados pela deficiência. Esclarecer esses mitos é um modo de superar a discriminação social e sexual que prejudica os ideais de uma sociedade inclusiva.

Repetition of Suicide Attempts Data from Emergency Care Settings in Five Culturally Different Low- and Middle-Income Countries Participating in the WHO SUPRE-MISS Study

Background: Attempted suicide is a strong risk factor for subsequent suicidal behaviors. Innovative strategies to deal with people who have attempted suicide are needed, particularly in resource-poor settings. Aims: To evaluate a brief educational intervention and periodic follow-up contacts (BIC) for suicide attempters in five culturally different sites (Campinas, Brazil; Chennai, India; Colombo, Sri Lanka; Karaj, Islamic Republic of Iran; and Yuncheng, People's Republic of China) as part of the WHO Multisite Intervention Study on Suicidal Behaviors (SUPRE-MISS). Methods: Among the 1,867 suicide attempters enrolled in the emergency departments of the participating sites, 922 (49.4%) were randomly assigned to a brief intervention and contact (BIC) group and 945 (50.6%) to a treatment as usual (TAU) group. Repeated suicide attempts over the 18 months following the index attempt - the secondary outcome measure presented in this paper - were identified by follow-up calls or visits. Subsequent completed suicide - the primary outcome measure has been reported in a previous paper. Results: Overall, the proportion of subjects with repeated suicide attempts was similar in the BIC and TAU groups (7.6% vs. 7.5%, chi(2) = 0.013; p = .909), but there were differences in rates across the five sites. Conclusions: This study from five low-and middle-income countries does not confirm the effectiveness of brief educational intervention and follow-up contacts for suicide attempters in reducing subsequent repetition of suicide attempts up to 18 months after discharge from emergency departments.

Mortalidade e prognóstico específico em pacientes com insuficiência renal aguda

A variety of systems of risk factor stratification have been studied to predict the outcome in acute renal failure (ARF). OBJECTIVES. Assess and compare mortality and the Acute Tubular Necrosis Individual Severity Score (ATN-ISS) in patients with AFR treated in a university hospital. METHODS. A prospective analysis was made of 103 patients with a diagnosis of intrinsic ARF admitted to the Hospital das Clinicas da Faculdade de Medicina de Botucatu, UNESP. Patients were followed up until recovery of renal function or death. The Score ATN-ISS was recorded during the first hours of the assessment by a nephrologist. Results were reported as median or mean ± SD, with statistical significance of p<0.05. RESULTS. Fifty-one percent of patients were male with a mean age of 58 ± 36 years. Forty-four percent died in the hospital. Mortality was higher in patients from the surgical wards (52.7%) and in patients who were treated with dialysis (63.8%). The score ATN-ISS showed a good confidence level, with high discriminatory power (area under the curve of 0.95) and good accuracy. CONCLUSIONS. Mortality in this study was comparable to that found in literature. The ATN-ISS was shown to be a prognostic index with a high confidence level that could be routinely applied by nephrologists to patients with AFR.
