Relations between Depression, Alcohol and Gender in the Metropolitan Region of São Paulo, Brazil

Como parte do projeto GENACIS, este artigo visou estimar a prevalência de depressão em amostra urbana de São Paulo, Brasil, assim como a associação entre depressão e padrão de uso de álcool segundo gênero. Para tanto, foi realizado inquérito epidemiológico com amostra probabilística e por conglomerados, com um total de 2083 adultos. Utilizou-se o CIDI SF para identificação de depressão. A análise estatística utilizou o teste de Rao Scott e regressão logística multivariada. A taxa de resposta foi de 74,9%. Predominaram mulheres (58,8%), menores de 40 anos de idade (52%). A prevalência de depressão foi de 28,3% para as mulheres e 12,7% para os homens. Entre os homens, 61,1% são de bebedores no último ano e a depressão esteve associada ao padrão de consumo de álcool, à maior frequência de binge drinking e à presença de problemas decorrentes do álcool. Entre as mulheres, 69,5% são abstinentes e a depressão se associou à convivência com cônjuge com problemas devidos ao álcool. Os resultados ressaltam que a associação entre depressão e consumo de álcool é distinta entre os gêneros.

Transsexuality in the interface with, the gender relationships

Over the past 60 years, the advancement of the sciences, the urbanization process of industrial centers, the mediatical advancement, the new family arrangements, the conquers of sexual minorities: homosexuals, transsexuals, transvestites, among other phenomena, coupled with the emphasis on individualism, and upon obtaining mediatical visibility, have softened the ethos of gender relationships in such a way to insert other approaches to the hegemony of the heteronormativity, whose resonances are present in and through symbolic exchanges with the other being, through which the contemporary subject comprises the subjectivation process.

Semiparametric modeling of the spatial distribution of occupational accident risk in the casual labor market, Piracicaba, southeast Brazil

The objective of this study was to estimate the spatial distribution of work accident risk in the informal work market in the urban zone of an industrialized city in southeast Brazil and to examine concomitant effects of age, gender, and type of occupation after controlling for spatial risk variation. The basic methodology adopted was that of a population-based case-control study with particular interest focused on the spatial location of work. Cases were all casual workers in the city suffering work accidents during a one-year period; controls were selected from the source population of casual laborers by systematic random sampling of urban homes. The spatial distribution of work accidents was estimated via a semiparametric generalized additive model with a nonparametric bidimensional spline of the geographical coordinates of cases and controls as the nonlinear spatial component, and including age, gender, and occupation as linear predictive variables in the parametric component. We analyzed 1,918 cases and 2,245 controls between 1/11/2003 and 31/10/2004 in Piracicaba, Brazil. Areas of significantly high and low accident risk were identified in relation to mean risk in the study region (p < 0.01). Work accident risk for informal workers varied significantly in the study area. Significant age, gender, and occupational group effects on accident risk were identified after correcting for this spatial variation. A good understanding of high-risk groups and high-risk regions underpins the formulation of hypotheses concerning accident causality and the development of effective public accident prevention policies.

Seroprevalence of and risk factors for Toxoplasma gondii in sheep raised in the Jaboticabal microregion, São Paulo State, Brazil

Seroprevalence of and risk factors for toxoplasmosis in sheep from different properties in the Jaboticabal microregion, São Paulo State, Brazil were determined. Antibodies to Toxoplasma gondii were found in sera of 52.0% of 488 sheep tested by indirect fluorescent antibody test (IFAT >= 64). T gondii seropositivity in sheep was significantly associated with gender of the sheep, pasturing system, contact with cats, and the use of mineral supplements and the type of feed.

Mucosal Bridge of the Vocal Fold: Difficulties in the Diagnosis and Treatment

Mucosal bridges are rare laryngeal lesions probably of genetic origin. They may cause dysphonia of varying degrees, especially when associated with other laryngeal lesions such as vocal sulci and cysts. Reports on mucosal bridges are rare, and the better treatment is inconclusive.Aim. To report the authors' experience in 14 cases of mucosal bridge showing details on endoscopic examinations and treatment.Study Design. Retrospective study.Methods. We reviewed the medical records of 14 patients with a diagnosis of mucosal bridge confirmed by video-laryngostroboscopy and direct laryngoscopy who attended the Outpatient Clinic of Voice Disorders of the Discipline of Otorhinolaryngology, Botucatu Medical School, São Paulo State University, São Paulo. Data collected included information on gender, age, symptoms, time of onset, history of intubation, smoking status, alcohol intake, associated laryngeal lesions, treatment, and GRBAS (grade of hoarseness, roughness, breathiness, asthenia, and stress) scale ratings.Results. of 14 patients, 10 were females and four were males. There was a prevalence of adults (n = 12), with only two of the patients being younger than 13 years (10 and 13 years). Mucosal bridges showed no correlations with smoking, alcohol intake, or gastroesophageal and sinonasal symptoms. Voice abuse was reported in 50% of the cases that consisted of patients who had high-voice demand occupations. In seven cases, mucosal bridges were associated with other laryngeal lesions, particularly vocal cysts and sulci. All patients who underwent surgery and phonotherapy showed improved vocal quality.Conclusions. We documented 14 patients with dysphonia caused by mucosal bridge. Promising results were obtained with surgery.

Occurrence of tooth injuries in patients treated in hospital environment in the region of Aracatuba, Brazil during a 6-year period

Dental trauma has been considered as a public health problem that affects mainly children and youngsters and due to its impact on the patient's quality of life. This study presents the results of a 6-year survey of the occurrence and characteristics of dental trauma in patients admitted to the Service of Surgery and Oral and Maxillofacial Traumatology of the School of Dentistry of Aracatuba (UNESP, Brazil) after emergency care in hospital facilities in the region of Aracatuba, SP, Brazil. For such purpose, the clinical files of patients treated at the Service between 1999 and 2005 were reviewed. Information regarding gender, age, number of traumatized teeth, etiology and diagnosis of the trauma was collected from the files of patients with tooth injuries and recorded in case report forms specifically designed for this purpose. The results showed that from a total of 4112 patients admitted to the Service within the surveyed period, 266 (6.5%) had tooth injuries (172 males - 64.7%; 94 females - 35.3%). The total number of traumatized teeth was 496. Most patients belonged to the 16-20 year-old age group (20.3%) and the most frequent causes of tooth injuries were bicycle accidents (28.6%), motorcycle accidents (19.2%) and falls (18.8%). Injuries to the periodontal tissues were the most frequent type of tooth injuries (408 teeth; 82.26%), occurring in 118 primary and 290 permanent teeth. Among the injuries to the periodontal tissues, avulsion was the most common (32.86%) (29.41% for primary and 34.0% for permanent teeth), followed by extrusive luxation (19.15%) (25.21% for primary and 17.24% for permanent teeth). In conclusion, in the surveyed population, cases of tooth injuries were more frequent in males aged 16-20 years old due to cyclist accidents with predominance of injuries to the periodontal tissues, in particular, avulsions.

Symptoms of Temporomandibular Disorders in the Population: An Epidemiological Study

Aims: To estimate the prevalence of symptoms of temporomandibular disorders (TMD) as a function of age and gender, in a representative urban sample from the Brazilian population. Methods: A total of 1,230 inhabitants (51.5% women) aged 15 to 65 years were interviewed by a validated phone survey. Sample size had been previously calculated. TMD symptoms were assessed through five questions, as recommended by the American Academy of Orofacial Pain, in an attempt to identify possible TMD. Data were derived by age and gender. Prevalence of each TMD symptom, and of combination of symptoms, was calculated. Results: At least one TMD symptom was reported by 39.2% of the individuals. Pain related to TMD was noted by 25.6% of the population. Temporomandibular joint (TMJ) sound was the most common symptom of TMD, followed by TMJ pain and masticatory muscle pain. All symptoms were more prevalent in women than in men. With men used as the reference, a relative risk (RR) of at least one TMD symptom in women was 1.31 (95% confidence interval [CI] = 1.14 to 1.52). When at least two symptoms were present, the RR was 1.93 (95% CI = 1.49 to 2.51). For three or more TMD symptoms, the RR was 2.49 (95% CI = 1.67 to 3.71). Women were also more likely than men to have TMD pain (RR = 1.78; 9% CI = 1.45 to 2.18). Conclusion: Individual symptoms, as well as a combination of TMD symptoms, are prevalent in the Brazilian urban population and are more frequent in women than in men. Additional studies should focus on risk factors for and relevance of TMD for the sufferers. J OROFAC PAIN 2010;24:270-278

Stages of behavior change and perceived barriers to physical activity in the elderly living in a medium size city in Brazil

The aim was to analyze the prevalence of the stages of behavior change (BCS) and the perceived barriers to physical activity in older people residents in a medium size city of São Paulo state, Brazil. Seventy-nine older people participated of the study. The BCS was assessed by the Questionnaire of Behavior Chance Stages and those on perception of barriers by the Questionnaire on Barriers to the Practice of Physical Activity in Older People (QBPPAE). Statistical analyses was comprised by the Chi-square test (p<0.05). Data showed that: a) 64,6% of the older people do not practice physical activity and only 22,8% of them have been practicing it on a regular basis for more than 6 months; b) The most perceived barriers were: "Active enough", "Too old"; "Need to rest" and; "Disease or injury"; c) The BCS seems modulate significantly the perception of barriers (p<0.05). We can conclude that: a) most of the older people are in the pre-contemplation, contemplation and preparation stages of the BCS, yet; b) gender influences almost nothing with perception of barriers and; c) the BCS interferes with the type of perceived barriers. Such conclusions support the suggestions that it is necessary to develop specific strategies for different stages of behavior change if it is to minimize the barriers. This may help to find the most effective way to change to more active lifestyle in the elderly.

Epidemiological aspects of enteroparasitosis at daycare centers in the city of Botucatu, State of São Paulo, Brazil

Estimou-se a prevalência e a incidência de parasitas intestinais em crianças e funcionários de 5 creches municipais em Botucatu/SP. Foram realizados dois estudos seccionais em 2002 (N=379) e 2003 (N=397) e um estudo longitudinal observacional, onde as crianças de 2002 e 2003 foram seguidas por um ano. Foram aplicados questionários nos funcionários e nos pais das crianças, onde foram coletadas as seguintes variáveis: nível sócio-econômico, hábitos sanitários, moradia, idade, sexo e presença de animais domésticos. Foram realizados exames coproparasitológicos nas crianças das creches. A prevalência de enteroparasitas em 2002 foi de 76,74% e 34% em 2003. As variáveis associadas à presença de enteroparasitas no ano de 2002 foram: localização das creches (OR=0,27 IC=0,15-0,47), renda familiar (OR=4,38 IC=1,91-10,04), sexo (OR=0,52 IC=0,32-0,85), faixa etária (OR=2,08 IC=1,06-4,08) e presença de animais domésticos na casa (OR=1,85 IC=1,10-3,11); em 2003, as variáveis foram: creche localizada em bairro periférico (OR=0,49 IC=0,31-0,78), renda familiar (OR=3,69 IC=2,19-6,24), nível educacional da mãe (OR=6,19 IC=1,81-21,21), sexo (OR=0,36 IC=0,36-0,93) e presença de animais domésticos (OR=1,68 IC=1,01-2,79). A coorte foi integrada por 253 crianças apresentando incidência de 23,22%. Os dados deste estudo evidenciam situações de risco em populações específicas (creches) e poderiam ser utilizados por Instituições que promovem o cuidado com as crianças.

Anti-neutrophil cytoplasmic antibodies (ANCA) in the clinical forms of leprosy

Anti-neutrophil cytoplasmic antibodies (ANCA) are autoantibodies against enzymes present in primary granules of neutrophils and lysosomes of monocytes detected in systemic vasculitis and in other diseases, including infections, ANCA are markers of active Wegener granulomatosis, which presents some anatomo-pathologic and immune response features similar to those of leprosy. Thus, we raised the hypothesis that ANCA may be present in leprosy as markers specifically linked to the presence of vasculitis. The aim of this study was to determine the presence of ANCA in leprosy and its correlation with the clinical forms of the disease. Sera from 60 normal individuals and from 59 patients with different clinical forms of leprosy were studied. The patients were also allocated into reactional and nonreactional groups. By indirect immunofluorescence, ANCA were positive, an atypical pattern A-ANCA, in 28.8% of the patient sera. A-ANCA predominated, although not significantly (p >0,05), in the reactional groups (37.9% vs 20.0%), and in those at the lepromatous pole (41.6% vs 20.0%). There was no correlation between ANCA positivity and either disease duration, disease activity, or therapeutic regimen (p >0.05), An interesting finding was the correlation between ANCA and gender: 94.1% of ANCA-positive patients were males (p <0.01), a feature that so far has not been reported in ANCA-related diseases and for which there is no explanation at the moment. By ELISA, the sera of the lepromatous leprosy patients did not show activity against either PR3, MPO, HLE, the most common ANCA antigens. Because A-ANCA are nonspecific, this finding requires further investigation for the determination of the responsible antigen(s), in conclusion, A-ANCA are present in 28.8% of leprosy patients but are not related to vasculitis in the erythema nodosum leprosum reaction and are not a marker of a specific clinical form.

A second mutation in the methylenetetrahydrofolate reductase gene and the risk of venous thrombotic disease

We assessed the effect of a recently described mutation in the MTHFR gene (1298 A --> C) on the risk of deep venous thrombosis (DVT) by determining its prevalence in 190 patients with verified DVT and in age-, race- and gender-matched controls. MTHFR 1298 A --> C was found in 42.1% of patients and in 41.1% of controls. The OR for venous thrombosis was 1.07 (95% CI 0.70-1.65) for heterozygotes and 0.83 (95% CI 0.33-2.08) for homozygotes. The OR for the factor V Leiden (FVL) mutation was 3.40 (95% CI 1.22-9.48), for FII 20210 G --> A was 5.22 (95% CI 1.12-24.2) and for MTHFR 677 C --> T, 1.24 (95% CI 0.82-1.87). No significant increased risk for venous thrombosis was found when MTHFR 1298 A --> C was coinherited with FVL (OR 2.85, 95% CI 0.88-9.23), FIT 20210 G --> A (OR 7.19, 95% CT 0.87-59.4) or MTHFR 677 C --> T (OR 1.44, 95% CT 0.71-2.92). These data do not support a critical role of MTHFR 1298 A --> C in the predisposition to DVT.
