Desigualdade de indicadores de mortalidade no Sudeste do Brasil

INTRODUÇÃO: Há indícios de que a deterioração das condições de trabalho ocorrida em anos recentes influencie a mortalidade. O objetivo do estudo é estimar indicadores de mortalidade para a população de Botucatu, classificada de acordo com as ocupações exercidas. MÉTODO: Foram calculados os indicadores coeficiente de mortalidade padronizado (CMP), razão de risco padronizada e anos potenciais de vida perdidos (APVP) para a população de Botucatu, em 1997, segundo ocupações e causas básicas do óbito. RESULTADOS: Os indicadores CMP e APVP variaram entre 0,6 e 39,9 óbitos/1000 trabalhadores e entre 33 e 334 anos/1000 trabalhadores, respectivamente, de acordo com a ocupação principal exercida. Observou-se que a ordenação quantitativa das causas de óbito depende da ocupação e do indicador utilizado. CONCLUSÕES: Os indicadores de mortalidade verificados apresentam uma grande heterogeneidade quando analisados de acordo com ocupação e causas básicas de óbito, refletindo a enorme desigualdade social existente na população estudada.

Dental Practice and Musculoskeletal Disorders Association: A Look at the Evidence

Disorders localized to the musculoskeletal system are a common problem among dental personnel. This study has the aim of surveying epidemiological studies reporting positive associations between dental practice and musculoskeletal disorders (MSKDs). The focus was to evaluate the size of reported risk increase and the extent to what alternative causal explanations were considered. Reports with significant links (p value .05) were systematically selected from 2 electronic databases. Twenty-five studies were identified. Risk measures were reported in 8 studies, and all of them presented weak associations. The impact of at least 1 competing explanations was analyzed in 32% of studies, but adjustment was considered not adequate in half of them. The evidence on dentistry as a profession with potential risk for development of MSKDs remains questionable. Further research is needed to more carefully elucidate the risk and the impact of MSKDs in this particular occupational group.

Análise de risco em carteiras

The work consists of analyzing the risk management of investments by applying statistical concepts, economic and mathematical models considering the assets on the market on renowned financial institution. The assessment of these risks becomes increasingly interesting in view of minimizing your losses thus maximizing your chances of gains in both markets boom as extreme uncertainty, even with the sudden changes of scenery. Introducing concepts of investment funds, as well as the classification of the types of funds as funds management and equity, its guidelines, the concept of market investment funds. The types of assets comprising the investment funds, their taxation rules beyond the incidents that market widely used by investors and skilled people, both physical and legal, who keep their resources in this modality. With the historical data collected yields of investment funds of the Bank of Brazil, is an accomplished inflation adjustment and calculated the mean and variance for the verification of the model of Markowitz efficient frontier, a method used as investment analysis. This scan is used Matlab to obtain the set (or border) efficient portfolios. Once verified such data, there will be a critique of the Markowitz model as a quadratic programming and more coherent risk measures currently studied as VaR and CVaR minimizing the expected error, approaching our studies of current research. It is found that such studies have much to be explored, since there are many discussions about how effectively measure risk investments such as its characteristic and behavior, using a time series and volatility

Risk factors of oropharyngeal carriage of Pseudomonas aeruginosa among patients from a Medical-Surgical Intensive Care Unit

Oropharyngeal carriage of Pseudomonas aeruginosa is associated with increased risk of infection and may provide a source for spread of drug-resistant strains. In order to assess the incidence and risk factors of oropharyngeal carriage, we conducted a retrospective cohort study based on results of surveillance cultures (oropharyngeal swabs) from a medical-surgical intensive care unit, collected from March 2005 through May 2006. Variables investigated included demographic characteristics, comorbid conditions, invasive procedures, use of devices and use of antimicrobials. Thirty case patients with P. aeruginosa carriage were identified. Other 84 patients with surveillance cultures negative to P. aeruginosa were enrolled as control subjects. Case patients were more likely to have a solid malignancy (Odds Ratio [OR] = 12.04, 95% Confidence Interval [CI] = 1.93-75.09, p=0.008), Acquired Immunodeficiency Syndrome (AIDS, OR = 7.09, 95% CI=1.11-45.39, p = 0.04), central nervous system disease (OR = 4.51, 95% CI = 1.52-13.39, p = 0.007), or to have a central venous catheter placed (OR = 7.76, 95% CI = 1.68-35.79, p=0.009). The use of quinolones was a protective factor (OR = 0.13, 95% CI = 0.03-0.47, p = 0.002). The predominance of comorbidities as risk factors points out a group of patients to whom preventive measures should be directed.

Association between anthropometric indicators of body fat and metabolic risk markers in post-menopausal women

Objective. to evaluate anthropometric indicators of body fat and their association with metabolic risk markers in postmenopausal women.Methods. A cross-sectional study with 80 Brazilian women (40-70 years) was carried out. Body mass index (BMI = weight/height(2)), waist circumference (WC) and waist-to-hip ratio (WHR) were obtained for anthropometric evaluation. Trunk fat mass (TFM) was measured by dual-energy X-ray absorptiometry. The following metabolic variables were evaluated: total cholesterol (TC), HDL, LDL, triglycerides (TG), as well as glycemia and insulin to determine insulin resistance (HOMA-IR).Results. Overweight and obesity were observed in 81% of the women. Values of WC >88 cm were observed in 68.5% of the women. on average, TC, LDL and TG levels were above normal levels in 60, 50 and 42.5% of the women, respectively; and HDL was normal in 82.5%. IR was observed in 37.5% of the women. Positive correlations were found between anthropometric indicators and TFM (P < 0.05). WC was most correlated with TFM (r = 0.92), followed by BMI (r = 0.88) and by WHR (r = 0.48; P < 0.05). All anthropometric indicators and TFM showed significant negative correlations with HDL and significant positive correlations with HOMA-IR (P < 0.05). Only WHR was significantly associated with dysglycemia (R(2) = 12%), hypertriglyceridemia (R(2) = 17%) and decreased HDL (R(2) = 27%). WC was significantly associated with HOMA-IR (R(2) = 34%).Conclusion. WC and WHR are anthropometric measures that showed strong correlation with TFM and with metabolic risk markers in postmenopausal women.

The impact of prior preeclampsia on the risk of superimposed preeclampsia and other adverse pregnancy outcomes in patients with chronic hypertension

OBJECTIVE: We sought to compare the rates of superimposed preeclampsia and adverse outcomes in women with chronic hypertension with or without prior preeclampsia.STUDY DESIGN: We conducted secondary analysis of 369 women with chronic hypertension (104 with prior preeclampsia) enrolled at 12-19 weeks as part of a multisite trial of antioxidants to prevent preeclampsia (no reduction was found). Outcome measures were rates of superimposed preeclampsia and other adverse perinatal outcomes.RESULTS: Prepregnancy body mass index, blood pressure, and smoking status at enrollment were similar between groups. The rates of superimposed preeclampsia (17.3% vs 17.7%), abruptio placentae (1.0% vs 3.1%), perinatal death (6.7% vs 8.7%), and small for gestational age (18.4% vs 14.3%) were similar between groups, but preterm delivery <37 weeks was higher in the prior preeclampsia group (36.9% vs 27.1%; adjusted risk ratio, 1.46; 95% confidence interval, 1.05-2.03; P = .032).CONCLUSION: In women with chronic hypertension, a history of preeclampsia does not increase the rate of superimposed preeclampsia, but is associated with an increased rate of delivery at <37 weeks.

Risk factors and presence of antibodies to Toxoplasma gondii in dogs from the coast of São Paulo State, Brazil

A toxoplasmose é causada por um protozoário parasita intracelular obrigatório, Toxoplasma gondii, e acomete vertebrados homeotérmicos incluindo animais de companhia e o homem. O cão apresenta importância epidemiológica por atuar como sentinela da infecção para o homem. O presente estudo objetivou determinar a ocorrência de anticorpos para T. gondii em 205 amostras de soro de cães do município de Ubatuba, SP, Brasil, pela reação de imunofluorescência indireta (RIFI), assim como os fatores de risco relacionados à infecção nos animais, como raça, idade, sexo, acesso a rua, ingestão de comida caseira, acesso a água não tratada e presença de roedores. 52/205 (25,4%) amostras foram positivas para toxoplasmose, com títulos variando de 16 a 256. Os resultados sorológicos apresentaram associação significativa (P<0,05) com consumo de comida caseira (45/118; 38,1%; IC95% 29,9%-47,2%) (OR=7,0; CI95% 3,0-16,6), e acesso a rua, em que aqueles que não tinham acesso a rua foram prevalentes (37/121; 30,6%; IC95% 23,1%-39,3%) (OR=0,5; CI95% 0,2-1,0). Estes resultados demonstram que a toxoplasmose na região está relacionada com problema de educação sanitária, principalmente quanto ao adequado cozimento dos alimentos, visto que a maioria dos animais positivos não apresentou associação significativa com presença de roedores ou consumo de água não tratada, porém os mesmos permaneciam em casa aos quais fora oferecida comida caseira. Portanto, a toxoplasmose consiste em um problema de saúde pública na região estudada, sendo necessárias medidas sanitárias para o controle da infecção, visto a estreita relação homem-cão e os fatores de risco presentes.

Alcohol dehydrogenase 3 genotype as a risk factor for upper aerodigestive tract cancers

Objective: To assess alcohol dehydrogenase 3 (ADH3) polymorphism at position Ile349Val as indicator of risk factor for upper aerodigestive tract (UADT) cancer to verify its association with UADT cancer in nonalcoholic or nonsmoking individuals.Design: Cross-sectional study.Setting: Primary care or referral center.Patients: the study group consisted of 141 consecutive patients with newly diagnosed squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx admitted for surgical treatment. The comparison group consisted of 94 inpatients without cancer from the A. C. Camargo or other São Paulo (Brazil) hospital and 40 healthy individuals.Intervention: All participants were interviewed and data were collected using a structured questionnaire. After written informed consent was obtained, 20 mL of blood was collected in heparinized tubes.Main Outcome Measures: Odds ratio for ADH3 genotypes using logistic regression models.Results: After adjustment for sex, age, tobacco use, and history of cancer in first-degree family relatives, a significantly higher odds ratio for UADT cancer was observed among individuals with AA genotype and low cumulative alcohol consumption (:5 100 kg of ethanol) (odds ratio=3.8 [95% confidence interval, 1.5-9.7]). A 4-fold increase in odds ratio for UADT cancer among individuals with AA genotype and low tobacco consumption (:525 pack-years) was also found in the adjusted model.Conclusions: These results suggest that genotype AA may be a risk factor for UADT cancer, especially in individuals with low alcohol or tobacco consumption. However, further epidemiological case-control or cohort studies, preferably prospective, are needed to establish the exact role of ADH3 polymorphism and its association with the development of UADT cancers.

Prevalence of dog intestinal parasites and risk perception of zoonotic infection by dog owners in São Paulo State, Brazil

Coprological examination was used to estimate the prevalence of gastrointestinal parasites in stray and domiciled dogs from Botucatu, São Paulo State, Brazil. Risk factors for dog infection were assessed in relation to demographic, husbandry and management data. The dog owners completed a questionnaire survey on some aspects of dog parasitism such as parasite species, mechanisms of infection, awareness of zoonotic diseases and history of anthelmintic usage. Parasites were found in the faeces of 138 dogs, with an overall prevalence of 54.3%. Dogs harbouring one parasite were more common (31.4%) than those harbouring two (18.5%), three (3.2%) or four (1.2%). The following parasites and their respective frequencies were detected: Ancylostoma (37.8%), Giardia (16.9%), Toxocara canis (8.7%), Trichuris vulpis (7.1%), Dipylidium caninum (2.4%), Isospora (3.5%), Cryptosporidium (3.1%) and Sarcocystis (2.7%). Stray dogs were found more likely to be poliparasitized (P < 0.01) and presented higher prevalence of Ancylostoma, T. canis and Giardia (P < 0.01) than domiciled ones. Toxocara canis was detected more frequently in dogs with < 6 months of age (P < 0.05) and no effect of sex or breed could be observed (P > 0.05). Except for Ancylostoma, that showed a significantly higher prevalence in dogs living in a multi-dog household (P < 0.01), parasite prevalences were similar in single- and multi-dog household. The answers of dog owners to the questionnaire showed that the majority does not know the species of dog intestinal parasites, the mechanisms of transmission, the risk factors for zoonotic infections, and specific prophylactic measures. The predominance of zoonotic species in dogs in the studied region, associated with the elevated degree of misinformation of the owners, indicates that the risk of zoonotic infection by canine intestinal parasite may be high, even in one of the most developed regions of Brazil.

Prevalence and risk factors for Toxoplasma gondii infection in certified and non-certified pig breeding farms in the Toledo microregion, PR, Brazil

A infecção pelo Toxoplasma gondii tem sido diagnosticada em suínos em todo o mundo. Perdas econômicas geralmente estão relacionadas a distúrbios reprodutivos. A infecção pelo Toxoplasma tem também importância em saúde pública, já que cistos teciduais do parasito podem persistir na carne e subprodutos oriundos de suínos, que servirão de fontes de infecção para o ser humano. O objetivo deste trabalho foi verificar a frequência e os fatores de risco associados à infecção pelo Toxoplasma em granjas de reprodutores suídeos certificados ou não da microrregião de Toledo, no Paraná, que inclui os municípios de Toledo, Nova Santa Rosa, São José das Palmeiras e São Pedro do Iguaçú. A frequência relativa de infecção foi 13,4%, sem diferença com o tipo de granja. A análise de regressão logística demonstrou os seguintes fatores associados à infecção: não utilização de funcionários separados por área da granja, o acesso de animais ao cocho de ração e ao reservatório de água, a não utilização de tampa neste reservatório, a não prevenção de roedores, o número e peso médio de leitões ao desmame por porca.

Panretinal photocoagulation versus PRP plus intravitreal bevacizumab for high-risk proliferative diabetic retinopathy (IBeHi study)

Purpose: To evaluate the effects of panretinal photocoagulation (PRP) compared with PRP plus intravitreal bevacizumab on best corrected visual acuity (BCVA) and total area of fluorescein leakage from active new vessels (NVs) in patients with high-risk proliferative diabetic retinopathy (PDR).Methods: We carried out a prospective study of patients with high-risk PDR and no prior laser treatment who were randomly assigned to receive PRP (PRP group) or PRP plus intravitreal injection of 1.5 mg of bevacizumab (PRP-plus group). In all patients, the PRP was administered at two time-points (weeks 1 and 3), with the intravitreal bevacizumab delivered at the end of the second laser episode in the PRP-plus group. Standardized ophthalmic evaluation including Early Treatment Diabetic Retinopathy Study BCVA as well as stereoscopic fundus photography and fluorescein angiography were performed at baseline and at weeks 4, 9 (+/- 1) and 16 (+/- 2). Main outcome measures included changes in BCVA and in total area of fluorescein leakage from active NVs.Results: Twenty-two (n = 30 eyes) consecutive patients completed the 16-week follow-up. There was no significant difference between the PRP and PRP-plus groups with respect to age, gender, type or duration of diabetes, area of fluorescein leakage from active NVs or BCVA. No significant difference in BCVA was observed between the groups throughout the study period. However, the total area of actively leaking NVs was significantly reduced in the PRP-plus group compared with the PRP group at weeks 4, 9 and 16 (p < 0.001). No major adverse events were identified.Conclusions: In the short-term, the adjunctive use of intravitreal bevacizumab with PRP was associated with a greater reduction in the area of active leaking NVs than PRP alone in patients with high-risk PDR.
