E-mail: carrasco.lara@gmail.com Cryptosporidium spp. is recognized as an important etiologic agent of diarrhea in many countries. The aim of this study was to detect the presence of DNA of the parasite Cryptosporidium spp. in feces of cats with history of chronic diarrhea attended in the Feline Medicine Sector of the Veterinary Hospital of the Federal Rural University of Rio de Janeiro, by the polymerase chain reaction technique in real time (RT-PCR. In this study, 100 animals were admitted, of any breed or sex and from 8 weeks of age. As inclusion criteria, patients had to have diarrhea history for more than three weeks, with little success of clinical response to previously established therapies. From the samples obtained by collecting via washing the animal colon and spontaneous defecation, methods of direct examination of the feces, centrifugal flotation technique and real-time PCR were carried out. Of all cats selected for this study, 10% showed infection by Cryptosporidium spp. Most positive animals were aged over one year (70% and only 30% had up to one year old. Cats were 50% purebred and 50% were domestic short hair cats. The clinical signs presented by these cats at the time of consultation were diarrhea (60% and prolapsed rectum (40%. Four animals had co-infections with other enteropathogens (40%, such as Giardia, Toxocara sp. or Tritrichomonas fetus alone or combined. We concluded that infection by

    This study described the sociodemographic profile and professional qualifications of pediatric intensive care physicians in the State of Rio de Janeiro (RJ), southeastern Brazil. This investigation was an observational, cross-sectional and descriptive study that was conducted in neonatal, pediatric and mixed intensive care units in the State of Rio de Janeiro. Physicians working in the participating intensive care units voluntarily completed a semistructured and anonymous questionnaire. Questionnaires that were not returned within 30 days were considered lost, and questionnaires with less than 75% questions completed were excluded. The differences in neonatal and pediatric intensive care physicians' medical training were compared using the Chi-squared test with a 5% significance level. A total of 410 physicians were included in this study: 84% female, 48% between 30 and 39 years old and 45% with monthly incomes between US $1,700 to 2,700. Forty percent of these physicians worked exclusively in this specialty, and 72% worked in more than one intensive care unit. Only 50% of the participants had received specific training (either medical residency or specialization) in neonatology, and only 33% were board-certified specialists in this area. Only 27% of the physicians had received specific training in pediatric intensive care medicine, and only 17% were board-certified specialists (p professional activity; 49% were dissatisfied due to working conditions, 23% due to low incomes and 18% due to training-related issues. These results suggested that the medical qualifications of neonatal and pediatric intensive care physicians in the State of Rio de Janeiro, Brazil are inadequate, especially in pediatric intensive care medicine. A high level of dissatisfaction was reported, which may jeopardize the quality of medical assistance that is provided by these professionals.

    Full Text Available Abstract Background Blastocystis is a cosmopolitan protist parasite found in the human gastrointestinal tract and is highly prevalent in developing countries. Recent molecular studies have revealed extensive genetic diversity, which has been classified into different subtypes (STs based on sequence analysis of small subunit ribosomal RNA gene. Blastocystis is one of the most common fecal parasites in Brazil, but the diversity of subtypes remains unknown in the country. This study aimed to determine the distribution of Blastocystis STs in an urban community in Duque de Caxias, Rio de Janeiro, Brazil. Methods A total of 64 stool samples positive for Blastocystis in Pavlova’s medium were subtyped by PCR and sequenced using primers targeting the small subunit rRNA gene, in addition to phylogenetic analysis and subtype-specific PCR using sequence-tagged-site (STS primers. Results Endolimax nana (14%, Entamoeba complex (10.5%, Taenia sp. (0.6%, Trichuris trichiura (1.3% and Enterobius vermicularis (1.3% were detected in Blastocystis-positive samples. Of the 64 samples tested by PCR/DNA sequencing, 55 were identified as ST1 (42%, ST3 (49%, ST2 (7% and ST4 (2%, and the presence of mixed ST (ST1 + ST3 infection was detected in nine samples (14%. Conclusions DNA sequencing and phylogenetic analysis of Brazilian Blastocystis isolates identified four different subtypes. To our knowledge, this study provided the first genetic characterization of Blastocystis subtypes in an urban area of Rio de Janeiro, Brazil. We also identified ST4 for the first time in Brazil. Further studies are necessary to determine the distribution of STs across human populations in Rio de Janeiro.

    Full Text Available OBJECTIVE: Estimate the prevalence of psychotropic drugs use in the city of Rio de Janeiro, Brazil, and establish its relationship with the presence of mental disorders. METHODS: A probabilistic sample of non-institutionalized individuals, from the general population of Rio de Janeiro (n = 1208;turn out:81%, 15 years or older, who were interviewed using the Composite International Diagnostic Interview 2.1 (depression, anxiety-phobia, OCD\\PTSD, alcoholism sections, and asked about their psychotropic use during a 12 and one-month period before the interview. Data were collected between June/2007-February/2008.The prevalence was estimated with a confidence interval of 95%. The associations between psychotropics use and mental disorders were analyzed through a logistic regression model (Odds Ration - OR. RESULTS: The one-month prevalence of psychotropic drug use was 6.55%, 3.19% for men and 9.13% for women. Antidepressants were the most frequently used drug (2.78%, followed by anorectics (1.65%, tranquilizers (1.61% and mood stabilizers (1.23%. General practitioners issued the highest number of prescriptions (46.3%, followed by psychiatrists (29.3%; 86.6% of the psychotropic drugs used were paid for by the patient himself. Individuals with increased likelihood of using psychotropic drugs were those that had received a psychiatric diagnosis during a one-month period before the study (OR:3.93, females (OR:1.82, separated/divorced (OR:2.23, of increased age (OR:1.03, with higher income (OR:2.96, and family history of mental disorder (OR:2.59; only 16% of the individuals with a current DSM IV diagnosis were using a psychotropic drug; 17% among individuals with a depression-related diagnosis and 8% with Phobic Anxiety Disorders-related diagnosis used psychotropics. CONCLUSION: Approximately 84% of individuals displaying some mental disorder did not use psychotropic drugs, which indicates an important gap between demand and access to treatment. A

The unit of analysis was the home district registered in the Sistema de Informação de Agravos de Notificação (Notifiable Diseases Information System of Rio de Janeiro, Southeastern Brazil. The rates were standardized by sex and age group, and smoothed by the empirical Bayes method. Spatial autocorrelation was evaluated by Moran’s I. Multiple linear regression models were studied and the appropriateness of incorporating the spatial component in modeling was evaluated.RESULTS We observed a higher risk of the disease in some neighborhoods of the port and north regions, as well as a high incidence in the slums of Rocinha and Vidigal, in the south region, and Cidade de Deus, in the west. The final model identified a positive association for the variables: percentage of permanent private households in which the head of the house earns three to five minimum wages; percentage of individual residents in the neighborhood; and percentage of people living in homes with more than two people per bedroom.CONCLUSIONS The spatial analysis identified areas of risk of tuberculosis incidence in the neighborhoods of the city of Rio de Janeiro and also found spatial dependence for the incidence of tuberculosis and some socioeconomic variables. However, the inclusion of the space component in the final model was not required during the modeling process.

    The burden of HIV in transgender women (transwomen) in Brazil remains unknown. We aimed to estimate HIV prevalence among transwomen in Rio de Janeiro and to identify predictors of newly diagnosed HIV infections. We recruited transwomen from Rio de Janeiro, Brazil, by respondent-driven sampling. Eligibility criteria were self-identification as transwomen, being 18 years of age or older, living in Rio de Janeiro or its metropolitan area, and having a valid peer recruitment coupon. We recruited 12 seed participants from social movements and formative focus groups who then used peer recruitment coupons to refer subsequent peers to the study. We categorised participants as HIV negative, known HIV infected, or newly diagnosed as HIV infected. We assessed predictors of newly diagnosed HIV infections by comparing newly diagnosed with HIV-negative participants. We derived population estimates with the Respondent-Driven Sampling II estimator. Between Aug 1, 2015, and Jan 29, 2016, we enrolled 345 eligible transwomen. 29·1% (95% CI 23·2-35·4) of participants had no previous HIV testing (adjusted from 60 participants), 31·2% (18·8-43·6) had HIV infections (adjusted from 141 participants), and 7·0% (0·0-15·9) were newly diagnosed as HIV infected (adjusted from 40 participants). We diagnosed syphilis in 28·9% (18·0-39·8) of participants, rectal chlamydia in 14·6% (5·4-23·8), and gonorrhoea in 13·5% (3·2-23·8). Newly diagnosed HIV infections were associated with black race (odds ratio 22·8 [95% CI 2·9-178·9]; p=0·003), travesti (34·1 [5·8-200·2]; p=0·0001) or transsexual woman (41·3 [6·3-271·2]; p=0·0001) gender identity, history of sex work (30·7 [3·5-267·3]; p=0·002), and history of sniffing cocaine (4·4 [1·4-14·1]; p=0·01). Our results suggest that transwomen bear the largest burden of HIV among any population at risk in Brazil. The high proportion of HIV diagnosis among young participants points to the need for tailored long-term health

    Full Text Available In the developing countries of the world, few people with hemophilia receive adequate care. Nevertheless, Brazil has made significant advances in the treatment of hemophilia over the last decade. The provision of factor concentrates imported by the Government of Brazil is gradually increasing, and patients receive the concentrates for free. A national register was established as well as a coordinated program for comprehensive care. Of the 6 297 persons with hemophilia in Brazil who were registered as of January 2001, 689 of them (11.1% were registered in the state of Rio de Janeiro. Of those 689, 664 of them were being monitored at the state's coordinating blood transfusion center, which is located in the city of Rio de Janeiro. Among those 664, factor VIII inhibitors were identified in 81 of them (12.2%. Among 653 of the Rio de Janeiro patients who were tested for transfusion-transmitted diseases, the overall prevalence found was 41.5%, with the specific rates being 13.3% for human immunodeficiency virus (HIV, 2.9% for hepatitis B virus (HBV, and 39.4% for hepatitis C virus (HCV. The state of Rio de Janeiro has adopted a comprehensive hemophilia management approach that includes medical, psychological, and social care. As a result, the quality of life of hemophilia patients has improved noticeably. For example, the rate of hospitalization among patients fell by 30% between 1998 and 2001, and there has also been a decline in the school and work activities that they have missed.En los países en desarrollo, pocas personas con hemofilia reciben un tratamiento adecuado. No obstante, el Brasil ha logrado grandes avances en este sentido en el último decenio.

    In the scientific literature, sporotrichosis has traditionally been associated with agricultural work, since the causative agent is found naturally in the soil. However, cases have been reported recently in an urban area, related to zoonotic transmission. The current study aimed to contribute to knowledge on sporotrichosis in an urban area through an exploratory analysis of its socio-spatial distribution in Rio de Janeiro, Brazil, from 1997 to 2007, identifying the areas with the heaviest transmission. The database from the Health Surveillance Service at the Evandro Chagas Institute for Clinical Research, Oswaldo Cruz Foundation, was used to estimate incidence rates and spatial distribution. During the study period, 1,848 cases of sporotrichosis were reported, predominantly in adult women not currently in the labor market. The leading source of infection was wounds caused by domestic cats, which contributed to the spread of sporotrichosis in this urban area. Georeferencing of 1,681 cases showed a transmission belt along the border between the city of Rio de Janeiro and the adjacent municipalities in the Greater Metropolitan Area.

    Full Text Available CONTEXT: The relationship between body size and breast cancer still remains controversial in considering menopausal status. OBJECTIVE: To evaluate the association of height, weight and weight changes with breast cancer in the city of Rio de Janeiro, Brazil. DESIGN: Case-control study. SETTING: National Cancer Institute (INCA, Rio de Janeiro, Brazil, and State University of Rio de Janeiro (UERJ. SAMPLE: 177 incident cases of invasive breast cancer admitted to the main hospital of INCA between May 1995 and February 1996, and 377 controls recruited from among female visitors to the same hospital. MAIN MEASUREMENTS: Height and weight were measured and information on maximum weight, weight at ages 18 and 30 years, and potential risk factors were ascertained by interview at the hospital. RESULTS: Height was not related to risk of breast cancer among both pre and postmenopausal women. Nevertheless, women in this study were shorter than in studies that have found a positive association. Premenopausal women in the upper quartile of recent body mass index (BMI and maximum BMI showed a reduced risk of breast cancer (P for trend <= 0.03. Weight loss between ages 18 and 30 years and from 18 years to present was also associated with breast cancer among premenopausal women. CONCLUSIONS: These findings may merely indicate the known association between leanness and breast cancer. Further studies should explore the role of weight loss on breast cancer risk.

In field studies and reviews of herbarium collections, we identified five Hippeastrum species occurring in areas of restinga in the state of Rio de Janeiro. The five species identified could be distinguished according to the following palynological characteristics: pollen grain size, polarity, pollen units, shape, aperture (number and type, exine sculpture, colpus length and pattern of sexine ornamentation. Of the five species identified, Hippeastrum aulicum Herb. and H. glaucescens (Ker Gawl. Herb. were not identified in the field. Among the three species that were found in the field, H. striatum had the widest distribution in the study area, whereas the distribution of H. reticulatum was restricted to a single area of restinga, in the Jaconé district of the municipality of Saquarema. Through palynological examinations of specimens from herbaria in the state of Rio de Janeiro, we were able to confirm the identity of all five species of Hippeastrum studied. Our data represent a relevant contribution to increasing knowledge of this plant group in the region and will aid in future conservation efforts.

    To qualitatively assess the influence of patient-provider communication on contraceptive choice among HIV-positive women in the context of universal antiretroviral therapy (ART) access. Focus group discussions (FGD; n=3), in-depth (IDI; n=15) and freelist interviews (FLI; n=36) were conducted with HIV-positive women aged 18-40 years recruited from public health units in Rio de Janeiro/Brazil. Of 70 participants, 49 used ART and the median time since HIV diagnosis was 6 years (range: 1-18). The majority of participants (71.4%) reported some degree of dissatisfaction with their health providers (usually lack of open dialogue) and a few reported experiences of stigma/prejudice during appointments. Intra, interpersonal and social factors modulated behaviors and reproductive health decisions, and those issues were rarely addressed by providers during HIV clinical care. Despite dramatic increases in survival and life quality after universal ART implementation in Brazil, reproductive health issues are neglected by multiple cadres of HIV health providers. Communication on reproductive health issues remains fragmented and potentially contradictory, compromising care in these settings. Adequate provider training to address reproductive health-related issues in a comprehensive, culturally sensitive manner and improved integration of HIV and reproductive health care are urgently needed in this setting.

    Full Text Available In 2015, Brazil was faced with the cocirculation of three arboviruses of major public health importance. The emergence of Zika virus (ZIKV presents new challenges to both clinicians and public health authorities. Overlapping clinical features between diseases caused by ZIKV, Dengue (DENV and Chikungunya (CHIKV and the lack of validated serological assays for ZIKV make accurate diagnosis difficult.The outpatient service for acute febrile illnesses in Fiocruz initiated a syndromic clinical observational study in 2007 to capture unusual presentations of DENV infections. In January 2015, an increase of cases with exanthematic disease was observed. Trained physicians evaluated the patients using a detailed case report form that included clinical assessment and laboratory investigations. The laboratory diagnostic algorithm included assays for detection of ZIKV, CHIKV and DENV. 364 suspected cases of Zika virus disease were identified based on clinical criteria between January and July 2015. Of these, 262 (71.9% were tested and 119 (45.4% were confirmed by the detection of ZIKV RNA. All of the samples with sequence information available clustered within the Asian genotype.This is the first report of a ZIKV outbreak in the state of Rio de Janeiro, based on a large number of suspected (n = 364 and laboratory confirmed cases (n = 119. We were able to demonstrate that ZIKV was circulating in Rio de Janeiro as early as January 2015. The peak of the outbreak was documented in May/June 2015. More than half of the patients reported headache, arthralgia, myalgia, non-purulent conjunctivitis, and lower back pain, consistent with the case definition of suspected ZIKV disease issued by the Pan American Health Organization (PAHO. However, fever, when present, was low-intensity and short-termed. In our opinion, pruritus, the second most common clinical sign presented by the confirmed cases, should be added to the PAHO case definition, while fever could be given less

    Full Text Available Objective: The paper analyzes the supply and the utilization of hemodynamic services in Rio de Janeiro, Brazil.Methods: It's an exploratory study that uses data obtained from Brazilian official databases. The period of supply analysis was from 1999 to 2009, and of utilization was from 2008 to October 2012.Results: Since 1999 there is a growth of hemodynamic equipment purchase. The private sector concentrates most of the supply, but it has been reducing its availability to SUS. The rate between population and equipment in Brazil exceeds the ones of some rich countries. In the sense of supply, there are in 2009, a supply rate of 1,4 equipments for 1 million inhabitants in RJ state, larger than brazilian rate, of 3,4 but the rates are similar for public customers.Conclusion: Interventional cardiology procedures have improved in the state, but in a different way. And this is because the public hospitals at Rio de Janeiro have mostly reduced their production, while the private ones have increased their production. The observed result is the SUS users performing their procedures at great distances.

    Background The burden of HIV in transgender women (transwomen) in Brazil remains unknown. We aimed to estimate HIV prevalence among transwomen, and identify the factors associated with newly diagnosed HIV infections. Methods “Transcender” was a respondent driven sampling study of transwomen in Rio de Janeiro, Brazil, conducted from August 2015 to January 2016. Twelve seeds were recruited from social movements and formative phase. Eligibility criteria were: self-identification as transwomen, being 18 years of age or older, living in Rio de Janeiro or metropolitan area, and having a valid peer recruitment coupon. Participants were categorized as HIV-negative, known HIV infected, or newly diagnosed as HIV infected. Predictors of newly diagnosed HIV infections were assessed by comparing the newly diagnosed with the HIV-negative. Population estimates were adjusted using the RDSII estimator. Findings In total, 345 eligible transwomen were enrolled. The study sample was young and diverse on gender identity. Population estimates of no prior HIV testing, HIV-infection and newly diagnosed as HIV-infected were 29·1%, 32·1% and 7·0%, respectively (based on n=60 with no prior testing, n=141 HIV-infected, n=40 newly diagnosed). Syphilis, rectal chlamydia and gonorrhea infection were diagnosed in 28·9%, 14·6%, and 13·5%, respectively. Newly diagnosed HIV infections were associated with black race (22·8; 95%CI 2·9–178·9), travesti (34·1; 95%CI 5·8–200·2) or transsexual woman (41·3; 95%CI 6·3–271·2) gender identity, history of sex work (30·7; 95%CI 3·5–267·3), and history of sniffing cocaine (4·4; 95%CI 1·4–14·1). Interpretation Our results suggest that transwomen bear the largest burden of HIV among any population at risk in Brazil. The high proportion of HIV diagnosis among young participants points to the need for tailored long-term health care and prevention services in order to curb the HIV epidemic and improve the quality-of-life of

    SUMMARY The first epidemic of sporotrichosis in humans as a result of zoonotic transmission was identified in Rio de Janeiro, Brazil, in 1998. A cross-sectional study was conducted applying questionnaires to patients seen in 2002 at Evandro Chagas Clinical Research Institute, Fiocruz, with a confirmed diagnosis of sporotrichsosis. A total of 73 dwellings were studied, where 255 individuals, including 94 patients and 161 healthy household contacts, lived with 133 cats with sporotrichosis. Most dwellings were houses with 83% having complete basic sanitation. Among patients, there was a predominance of women with a median age of 41 years who were engaged in domestic activities. These women contracted the disease twice more often than men. The prevalence of sporotrichosis was four times higher among patients caring for animals, irrespective of gender. In the current epidemic of sporotrichosis, taking care of sick cats was the main factor associated with transmission of the disease to humans. PMID:18028580

  6. The dynamics of the production of AIDS-related stigma among pregnant women living with HIV/AIDS in Rio de Janeiro, Brazil

    Directory of Open Access Journals (Sweden)

    Simone Monteiro

    Full Text Available The study analyses the relationship between AIDS-related stigma and the processes of discrimination prior to diagnosis among pregnant women living with HIV/AIDS. The fieldwork involved interviews about the life trajectories of 29 pregnant women living with HIV/AIDS, recruited at two AIDS services in Rio de Janeiro, Brazil. The analysis revealed that before HIV diagnosis, social and gender inequalities experienced by these women reduced their access to material and symbolic goods that could have enhanced educational and career prospects and their ability and autonomy to exercise sexual and reproductive rights. Being diagnosed with HIV triggered fear of moral judgment and of breakdown in social and family support networks. Given these fears, pregnant women living with HIV/AIDS opt for concealment of the diagnosis. It is necessary for health services, NGOs and government agencies to work together to face the factors that fuel stigma, such as socioeconomic and gender inequalities, taboos and prejudices related to sexuality, and also develop actions to enable women to redefine the meaning of the disease.

    This is a study of the organization of public health services in the state of Rio de Janeiro concerning the diagnosis of potentially malignant disorders. Secondary data from the database of the first phase of the Program for Enhancement for Access to and Quality of Primary Care were used. The implementation of actions at different levels for cancer prevention, the availability of diagnostic support services and the organization of the care network were assessed. The results show that only 58.8% of oral health teams record and monitor suspect cases; that only 47.1% reported having preferential channels for referring patients and there is great variation in waiting times to confirm the diagnosis. Local managerial and regional support actions can improve the organization of the care network for oral cancer prevention in the state.

    How professionals are compensated may affect how they perform their tasks. Fixed compensation may take the form of wages, payment for productivity or capitation. In addition to fixed compensation, there are numerous mechanisms for variable compensation. This article describes the experience of Curitiba and Rio de Janeiro in Brazil, and Lisbon in Portugal, using different models of performance-based compensation. In all three of these examples, management felt the need to offer monetary reward to achieve certain goals. The indicators analyzed the structure, processes and outcomes, and assessed professionals individual and as part of healthcare teams. In Lisbon, variable compensation can be as high as 40% of the base wage, while in Curitiba and Rio de Janeiro it is limited to 10%. Despite the growing use of this management tool in Brazil and the world, further studies are required to analyze the effectiveness of variable compensation.

    Poisoning is one of the three main means used in suicide and suicides attempts. In order to improve the quality of such information, a cross-sectional descriptive study was conducted on case records in the State of Rio de Janeiro, Brazil, from 2006 to 2008, in the databases of the Information System on Diseases of Notification (SINAN), the Mortality Information System (SIM), and the Poison Control Center in Niterói (CCIn-Niterói). Probabilistic linkage was used to develop a model for monitoring suicides and suicide attempts by poisoning. Although 68.8% of the 948 records at CCIn had been reported by health professionals, only 2.6% were included in the other databases. Linking CCIn and SIM showed 61.3% underreporting. Information is important for surveillance, public policy-making, and decision-making. Probabilistic linkage allowed identifying problems in each system and provided better data quality and a more accurate diagnosis of the real situation in a complex and serious problem like suicidal behavior.

    Full Text Available Bat species richness in Neotropical localities is generally higher than that of any other group of mammals, and surveys of local bat assemblages may provide useful data for conservation management plans. Although the bat fauna of the Rio de Janeiro state is currently one of the best known in Brazil, there are several localities not adequately surveyed yet, and most of them are in the mountainous regions and in the northern portion of the state. From January 2008 to November 2009, we conducted surveys of bats in three localities in the state of Rio de Janeiro (municipalities of Varre-Sai, Sumidouro, and Cantagalo, and our fieldwork constitutes the first assessment of the bat assemblages of these localities. Surveys were conducted using mist nets in four different habitat types in each locality (forest interior, forest edge, riparian forest, and open areas [pastures]. We captured a total of 148 individuals in 17 species, 14 genera and 3 families. Among them, 11 species were recorded in Sumidouro, seven in Cantagalo, and nine in Varre-Sai. Although species richness was low compared with previous surveys in other close localities, we recorded species that have been rarely sampled in Southeastern Brazil (e.g., Macrophyllum macrophyllum [Phyllostomidae]. The results reinforce the importance of sampling different habitats in short surveys to improve the number of species registered.

    Spatial and temporal patterns of rainfall were identified over the state of Rio de Janeiro, southeast Brazil. The proximity to the coast and the complex topography create great diversity of rainfall over space and time. The dataset consisted of time series (1967-2013) of monthly rainfall over 100 meteorological stations. Clustering analysis made it possible to divide the stations into six groups (G1, G2, G3, G4, G5 and G6) with similar rainfall spatio-temporal patterns. A linear regression model was applied to a time series and a reference. The reference series was calculated from the average rainfall within a group, using nearby stations with higher correlation (Pearson). Based on t-test ( p River (G5) and the metropolitan area of the city of Rio de Janeiro (G6). The driest months in all regions were June, July and August, while November, December and January were the rainiest months. Sharp transitions occurred when considering monthly accumulated rainfall: from January to February, and from February to March, likely associated with episodes of "veranicos", i.e., periods of 4-15 days of duration with no rainfall.

    The exposure to cosmic radiation in aircraft travel is significantly higher than at ground level and varies with the route due to the effect of latitude, the altitude of flight, the flight time, and the year according to the solar cycle effects in galactic cosmic ray flux. A database, including about 4000 domestic flights in Brazil, was implemented in Excel spreadsheets based on data flights for November 2011. The fields included on the database are the origin and destination of flights, time of departure and arrival, plane type, number of passengers, airline and total time of flight. In this work, doses from flights to and from the town of Rio de Janeiro within Brazil have been assessed using the computer program CARI-6, developed by the U.S. Federal Aviation Administration, that calculates the effective dose of galactic cosmic radiation received by an individual in an aircraft flying the shortest route between two airports of the world. Average effective doses for individual flights ranged from 0.2 to 8.8 μSv. This is a very small contribution to average overall exposure to natural background radiation (2.4 mSv/y). A frequent flyer with weekly flights on the most usual route, Rio-São Paulo, would receive about 0.18 mSv/y, which means about 7,5 % increase to its usual exposure to natural radiation sources. Collective dose to passengers due to all national flights to and from Rio de Janeiro was estimated to be about 100 manSv per year. (author)

    This paper shows the result of a study on the extent of cocaine contamination in Real banknotes in circulation in the state of Rio de Janeiro (Brazil). A study of the percentage of contaminated banknotes was made, as well as a study on the contamination of banknotes based on different values, and a study of contamination depending on the region where the banknote was collected. The idea of this last study was to verify if the peculiar characteristics of the region of study (in particular, the city of Rio de Janeiro) influence the amount of cocaine in the banknotes. Some regions have higher consumption/drug trafficking of cocaine than others. Also, some contaminated banknotes confiscated directly from drug dealers and users were analyzed. Also, is showed in this paper all the optimization of the available analytical techniques for making the measurements possible. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Dengue fever is currently the most important arthropod-borne viral disease in Brazil. Mathematical modeling of disease dynamics is a very useful tool for the evaluation of control measures. To be used in decision-making, however, a mathematical model must be carefully parameterized and validated with epidemiological and entomological data. In this work, we developed a simple dengue model to answer three questions: (i which parameters are worth pursuing in the field in order to develop a dengue transmission model for Brazilian cities; (ii how vector density spatial heterogeneity influences control efforts; (iii with a degree of uncertainty, what is the invasion potential of dengue virus type 4 (DEN-4 in Rio de Janeiro city. Our model consists of an expression for the basic reproductive number (R0 that incorporates vector density spatial heterogeneity. To deal with the uncertainty regarding parameter values, we parameterized the model using a priori probability density functions covering a range of plausible values for each parameter. Using the Latin Hypercube Sampling procedure, values for the parameters were generated. We conclude that, even in the presence of vector spatial heterogeneity, the two most important entomological parameters to be estimated in the field are the mortality rate and the extrinsic incubation period. The spatial heterogeneity of the vector population increases the risk of epidemics and makes the control strategies more complex. At last, we conclude that Rio de Janeiro is at risk of a DEN-4 invasion. Finally, we stress the point that epidemiologists, mathematicians, and entomologists need to interact more to find better approaches to the measuring and interpretation of the transmission dynamics of arthropod-borne diseases.

    Sporotrichosis associated with zoonotic transmission remains a relevant public health problem in Rio de Janeiro, Brazil, affecting a large at-risk population, which includes HIV-infected individuals. We assessed patients co-infected by Sporothrix spp. and HIV over time in the context of an unabated sporotrichosis epidemic. A retrospective cohort retrieved information from a National reference institute for infectious diseases regarding 48 patients with sporotrichosis-HIV co-infection (group 1) as well as 3,570 patients with sporotrichosis (group 2), from 1987 through March 2013. Most patients from group 1 were male (68.8%), whereas women were predominant in group 2 (69.1%; psporotrichosis over time, whereas hospitalization was very unlikely in group 2, among whom approximately 1% were hospitalized over time. Dissemination of sporotrichosis was the main cause of hospitalization in both groups, although it was more common among hospitalized patients from group 1 (19/21 [90.5%] vs. 16/37 [43.2%]; psporotrichosis (3/48 vs. 5/3,570). The diagnosis of sporotrichosis elicited HIV testing and subsequent diagnosis in 19/48 patients, whereas 23/48 patients were simultaneously diagnosed with the two infections. HIV infection aggravates sporotrichosis, with a higher incidence of severe disseminated cases and a higher number of hospitalizations and deaths. Underserved populations, among whom sporotrichosis has been propagated, have been affected by different transmissible (e.g., HIV) and non-transmissible diseases. These populations should be targeted by community development programs and entitled to integrated management and care of their superimposed burdens.

    During the 40's and 50's there had been a hexachlorocyclohexane(HCH) industry in Duque de Caxias, state of Rio de Janeiro, Brazil. Duque de Caxias is a very important borough within the state's political and administrative structure. It is located in a strategic point connecting Minas Gerais and Rio de Janeiro. It also holds one of Brazil's greatest petroleum refineries. For 20 years, this factory (which is located next to an orphanage called Cidade dos Meninos, an area belonging to the Ministry of Social Assistance) produced thousands of tons of HCH and also other pesticides, such as DDT, DDD and DDE. In the beginning of the 60's, the industry had its activities stopped1. In 1989, significant amounts of HCH had been found by local inspectors in Duque de Caxias, where it had been being sold for use in agriculture. Once the product's usage had already been prohibited in Brazil, after a investigation authorities found that it would come from the inactive industry. Both environmental and public health institutions decided to use a mixture of lime and soil, in order to destroy the residues and organic compounds found in the old plant. Such procedure would cause a greater problem, for the lime used wouldn't meet the right proportions of the large area and its contaminated soil. In addition, it also affected the water supply and the local population. The consequences have been disastrous. Data referring to breastfeeding and blood revealed alarming pesticide rates that endangered the local people health conditions both in short and long term. After 14 years, monitoring is still necessary in that region so it is possible to control contamination and its damage related to secondary reactions, climatic effects and soil structure. For this reason, a monitoring program has been developed in order to investigate the rates of certain pesticides and PCDD/F in locations near the contamination field.

    Full Text Available The aim of the present study is to describe the type and frequency of bladder dysfunction in a series of female patients with multiple sclerosis (MS from Rio de Janeiro, and analyze the role of the urologist in the multidisciplinary team. A team of urologists and a neurologist from the Hospital da Lagoa, Rio de Janeiro, Brazil, interviewed female patients with MS about illness onset, urologic follow-up since diagnosis, current stage of the disease and current urological symptoms. The interview was followed by an urodynamic testing, ultrasound of the urinary tract and urinalysis. Data resulting from the interviews and exam results were gathered and submitted to statistical evaluation. Sixty one patients were evaluated, with average age of 41.4 years. Urinary symptoms such as urinary incontinence, urinary hesitancy, urinary retention, urinary urgency and incomplete bladder emptying were reported in 44% of patients as initial signs of MS disease. Mean disease duration was 8 years and all patients (100% with the primary progressive form of the disease and 63.5% with the relapsing-remitting presentation had urological symptoms. Analysis of complementary exams showed that 37.7% of urinalysis, 8.2% of the urinary tract ultrasound exams and 66.7% of the urodynamic evaluations were abnormal and the most frequent abnormality were overactive neurogenic bladder. Only 4 patients (6.6% had seen an urologist during the course of their disease and only 1.6% had performed an urodynamic evaluation. This study shows a high prevalence (68% of urinary dysfunction in a female population with MS. Urologic care should be part of the multidisciplinary team since the beginning of the disease. An urodynamic evaluation and simple urinalysis should be included in the routine testing during disease follow-up due to the high incidence of neurogenic bladder and other urologic complications.

    Full Text Available The occurrence and fate of trace-level contamination of pharmaceuticals in the aquatic environment has been recognized as one of the emerging issues in environmental chemistry. The effluents of wastewater treatment plants, usually directly emitted to the environment, often contain the anti-inflammatory drug diclofenac. Diclofenac was chosen because it is of high consumption; by background literature indicate toxic effects on biota and the lack of profile in sewage removal provided by the city. For this purpose, a survey on the presence of diclofenac in urban wastewater of Rio de Janeiro was carried out. It were evaluated diclofenac concentration in the affluent and effluent from wastewater treatment plant (WWTP Penha and Ilha do Governador, Rio de Janeiro, Brazil. Samples were collected along the line of treatment of each WWTP, and for clean up the samples were solid phase extraction (SPE, analysed by high performance liquid chromatography (HPLC, assisted by diode array detector (DAD techniques. The removal efficiency of pharmaceuticals in the wastewater treatment plants was roughly evaluated. Diclofenac was detected in all samples analysed wastewater (treated and raw, which confirms the low removal efficiency of conventional treatment systems, aerobes and anaerobes.

    Full Text Available ABSTRACT This study surveyed species of the family Araceae in Grumari restinga, located in the metropolitan region of the city of Rio de Janeiro, Brazil. We aimed to: i evaluate the contribution of a single locality (Grumari restinga to regional conservation (Rio de Janeiro State of Araceae; and ii compare the distribution of species of Araceae among restingas of the state. We calculated the extent of occurrence and the area of occupancy in the entire state for eight species of Araceae found in Grumari,and performed a similarity analysis among restingas. Our data demonstrate that the extent of occurrences for Anthurium augustinum, A. coriaceum and A. maricense are influenced by Grumari because this area is the boundary of their known distribution in the state. Grumari did not have an influence on the distribution of the other studied species. We found Anthurium coriaceum, A. luschnathianum and Philodendron crassinervium to exhibit unusual habits as terrestrial plants in sandy soil. The similarity analysis identified six groups of Araceae, four of which are related to the distance from adjacent forests. We demonstrated that this small conservation unit represents a key locality in the preservation of natural populations of species of Araceae in Rio de Janeiro State.

    Full Text Available A lethal case of Brazilian spotted fever (BSF is presented. Clinical features were initially of gastrointestinal involvement and evolved with progression to septic shock, meningoencephalitis and death on the 6th day of illness. Indirect immunofluorescence assay (IFA for spotted fever group rickettsia (SFGR was non-reactive. Diagnosis was confirmed by the polymerase chain reaction (PCR and the nucleotide sequencing of a fragment of the ompA gene showed 100% homology to Rickettsia rickettsii. BSF has not been reported in the city of Rio de Janeiro in the last three decades, and the present description should alert the clinicians to its presence in urban Rio de Janeiro, and to the differential diagnosis with dengue fever, gastroenteritis, leptospirosis and bacterial septic shock, among others.

    The growth and nutritional status of 185 school-aged children (97 boys and 88 girls) of low socio-economic level in Nova Iguaçú, State of Rio de Janeiro, Brazil, were studied. Nutritional anthropometry identified 3.52 and 6.25% of the children as suffering from wasting and stunting, respectively. These prevalences of malnutrition were comparable to those described in pre-school children living in a "favela" (shanty town) of Rio de Janeiro. In general, the median height fell below the 25th centile of the international standard of growth. The value of 10 year-old boys fell below the 10th centile. The mean values of weight and height of these children were comparable to those of children from the Northeastern region of Brazil ("Nordeste"), higher than those found for children in the State of Paraíba, Brazil, and lower than those for middle-class children of the State of S. Paulo. Skinfold thickness, arm circumference, and arm fat area data were higher in girls than boys. However, arm muscle are values in boys were superior in comparison to those of girls.

    Full Text Available Sanitary sewage collection and treatment is a serious environmental problem in Brazilian cities, as well as the destination of solid waste resulting from this process, i.e. the sewage sludge, a substance rich in organic matter and nutrients, which is normally discarded in landfills. The aim of this study was to characterize the sewage sludge generated in four treatment stations in Rio de Janeiro State, Brazil and check if they meet the legal criteria of the National Environment Council (CONAMA, Resolution No. 375/2006. It also focused on analyzing the perspectives for its agricultural recycling based on the potential demand for main agricultural crops grown in Rio de Janeiro State. Samples from eight sewage sludge lots from four treatment stations located in the metropolitan area of Rio de Janeiro were analyzed. These stations receive and treat only domestic sewage by activated sludge system. For chemical and biological characterization of these lots, representative samples were collected and analyzed according to parameters of CONAMA Resolution No. 375/2006. In order to analyze the perspectives of agricultural recycling of sewage sludge in Rio de Janeiro State, 10 crops with the largest cultivated area in the state were surveyed and analyzed which of them are apt to receive sewage sludge as fertilizer and/or soil amendment. To determine the potential demand for sewage sludge in agriculture, the area occupied by these crops were multiplied by each fertilizer recommendation considering the sewage sludge as fertilizer. The analyzed sludge presented a high content of nutrients and organic matter and was included in the parameters of heavy metals, pathogenic agents, and bacteriological indicators stipulated by CONAMA Resolution No. 375/2006. The agricultural panorama of Rio de Janeiro State is favorable for agricultural recycling of sewage sludge since there is a great potential demand for this residue and, among the 10 agricultural crops with the

These include data on the epidemiology, clinic-pathological aspects, bacteriological, virological and ultramicroscopic examinations, the experimental reproduction of the disease and cross immunity tests with classical swine fever virus performed in Brazil, and on the confirmation with isolation of the virus and determination of its identity at the Plum Island Animal Disease Center, New York, USA. The pigs of the affected herd had been fed untreated remains of meals from airplanes of international lines flying to Brazil from Portugal and Spain where ASF was occurring at the time. According to publication by the Ministry of Agriculture, after the diagnosis of the outbreak of ASF described in this paper, 223 additional outbreaks were reported in Brazil between 1978 and 1979, in all the Brazilian regions (North, Northeast, Central-West, Southeast and South. Further outbreaks were reported in 1981, but their number is not known. The last case was reported to have occurred on November 15, 1981, and on December 5, 1984, Brazil was declared free of ASF.

    Full Text Available SUMMARY American visceral leishmaniasis is a vector-borne zoonosis in expansion in Brazil. Dogs are the main urban reservoir. Departing from a case of canine visceral leishmaniasis (CVL in Jacaré, Niterói, Rio de Janeiro State, an epidemiological canine and entomological study was performed to assess the extension of the disease at the location. Sample was collected around the case and the dogs identified by serological tests (rapid double platform immunochromatographic exams, immunoenzymatic assay/ELISA, indirect immunofluorescence/IFAT. The parasitological diagnosis was performed in animals positive in at least one of these tests. The entomological study was carried out by using light traps and manual collection. The associations between canine variables and outcome (ELISA and IFAT reagents were assessed by the chi-square test and adjusted by multivariate logistic regression for those associations with p < 0.1 in the bivariate analysis. Seventeen cases of CVL were detected among 110 evaluated dogs (prevalence of 15.5%. Presence of ectoparasites (OR 6.5; 95% CI 1.1-37.4, animals with clinical signs (OR 9.5; 95% CI 1.2-76.6, and previous cases of CVL in the same house (OR 17.9; 95% CI 2.2-147.1 were associated with the outcome.

    Full Text Available Ticks were obtained from dogs from February to September of 1999 at weekly intervals, in the County of Piraí, State of Rio de Janeiro. Four hundred seventy four ixodids were taxonomically identified, 103 Amblyomma cajennense, seven Amblyomma ovale, 209 Rhipicephalus sanguineus, and 155 Amblyomma sp. An hemolymph test associated with Giemsa's stain revealed two specimens in 163 ticks tested (R. sanguineus and Amblyomma sp, containing rickettsia-like organisms. Direct immunofluorescence verified the presence of spotted fever group rickettsia in one specimen of R. sanguineus. Considering the limited information on rickettsiosis in Brazil, principally in relation to the vectors involved in perpetuating it in foci, these preliminary results give us an idea on the importance of infection in ticks, allowing to expand our knowledge on this zoonosis.

    Full Text Available Costs of tuberculosis diagnosis and treatment may represent a significant burden for the poor and for the health system in resource-poor countries.The aim of this study was to analyze patients' costs of tuberculosis care and to estimate the incremental cost-effectiveness ratio (ICER of the directly observed treatment (DOT strategy per completed treatment in Rio de Janeiro, Brazil.We interviewed 218 adult patients with bacteriologically confirmed pulmonary tuberculosis. Information on direct (out-of-pocket expenses and indirect (hours lost costs, loss in income and costs with extra help were gathered through a questionnaire. Healthcare system additional costs due to supervision of pill-intake were calculated considering staff salaries. Effectiveness was measured by treatment completion rate. The ICER of DOT compared to self-administered therapy (SAT was calculated.DOT increased costs during the treatment phase, while SAT increased costs in the pre-diagnostic phase, for both the patient and the health system. Treatment completion rates were 71% in SAT facilities and 79% in DOT facilities. Costs per completed treatment were US$ 194 for patients and U$ 189 for the health system in SAT facilities, compared to US$ 336 and US$ 726 in DOT facilities. The ICER was US$ 6,616 per completed DOT treatment compared to SAT.Costs incurred by TB patients are high in Rio de Janeiro, especially for those under DOT. The DOT strategy doubles patients' costs and increases by fourfold the health system costs per completed treatment. The additional costs for DOT may be one of the contributing factors to the completion rates below the targeted 85% recommended by WHO.

    Flávia L. P. C. Pellegrino

    Full Text Available Previous analysis of Pseudomonas aeruginosa class-1 integrons from Rio de Janeiro, Brazil, revealed the blaGES gene in one isolate. We screened isolates of two widespread PFGE genotypes, A and B, at a public hospital in Rio, for the presence of blaGES. The gene was detected in all seven P. aeruginosa isolates belonging to genotype B. Three of the seven genotype-B isolates were resistant to amikacin, aztreonam, ceftazidime, cefepime, ciprofloxacin, gentamicin, imipenem, meropenem, piperacillin-tazobactam and ticarcillin-clavulanic acid. The other four isolates were resistant to all these agents, except gentamicin, imipenem, meropenem and piperacillin-tazobactam. A synergistic effect between ceftazidime and imipenem or clavulanic acid suggested the production of GES-type ESBL.

    The induction of cytochrome P4501A-mediated activity (e.g. ethoxyresorufin-O-deethylation, EROD) has been used as a biomarker for monitoring fish exposure to AhR-receptor ligands such as polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB) and polychlorinated dibenzo-dioxins/furans (PCDD/Fs). In this study we found that hepatic EROD is induced in fish ('Nile tilapia', Oreochromis niloticus and 'acara', Geophagus brasiliensis) from the Guandu River (7-17-fold) and Jacarepagua Lake (7-fold), Rio de Janeiro, Brazil. Since both cichlid fish are consumed by the local population and the Guandu River is the main source of the drinking water supply for the greater Rio de Janeiro metropolitan area, pollution by cytochrome P4501A-inducing chemicals is a cause for concern and should be further investigated in sediments, water and biota. We additionally showed that EROD activity in the fish liver post-mitochondrial supernatant-simpler, cheaper and less time consuming to prepare than the microsomal fraction-is sufficiently sensitive for monitoring purposes. - Increased EROD activity in the liver of cichlid fishes indicated that Guandu River, the source of drinking water supply for Rio de Janeiro is polluted by CYP1A-inducing chemicals

    This study focused on views towards emergency contraception among pharmacy attendants in Greater Metropolitan Rio de Janeiro, Brazil. The empirical material came from a socio-anthropological study with 20 semi-structured interviews of pharmacy attendants of both sexes (8 females and 12 males). The interviews showed negative views of emergency contraception, emphasizing its potential health risks. Interviews considered emergency contraception a "hormone bomb" that can harm the female reproductive organs and other organ systems. The pharmacy attendants highlighted the risks of "uncontrolled" or "indiscriminate" use, especially by adolescents and young women. Since they considered it "dangerous" to women's bodies, they assigned the responsibility for orientation and counseling on use of the method to gynecologists rather than to pharmacists. The article discusses the need to expand the public debate on emergency contraception in Brazil to include pharmacists and pharmacy attendants, in addition to health professionals in general and teachers.

    To clarify the seroprevalence of human T-cell lymphotropic virus type I (HTLV-I) among hematologic and cancer patients in the State of Rio de Janeiro, Brazil, we investigated sera from 2430 individuals from the following groups: 152 patients with T-cell diseases, 250 with B-cell disorders, 67 with myeloid leukemia, 41 with Hodgkin's disease, 351 with a history of multiple blood transfusions, 235 patients with solid tumors of different types, and 109 family members of HTLV-I-infected patients. Antibodies to HTLV-I were screened by enzyme-linked immunosorbent assay or particle agglutination assays (or both). Repeatedly reactive samples were tested by Western blot and polymerase chain reaction assay to differentiate HTLV-I from HTLV-II. We found an increased seroprevalence rate of HTLV-I among those with lymphoid malignancies, mainly in T-cell diseases (28.9%), and these results were important in characterizing 44 cases of adult T-cell leukemia/lymphoma. We confirmed the presence of HTLV-I and HTLV-II infections in blood donors (0.4% and 0.1%, respectively), in patients exposed to multiple blood transfusions (10.2% and 0.8%, respectively), and in 30 (27.5%) of 109 family members of HTLV-I- or HTLV-II-infected patients. We also confirmed the high rate occurrence of adult T-cell leukemia/lymphoma among lymphoproliferative disorders in Rio de Janeiro, Brazil.

    Highlights: ► We constructed future scenarios of emissions of greenhouse gases in waste. ► Was used the IPCC methodology for calculating emission inventories. ► We calculated the costs of abatement for emissions reduction in landfill waste. ► The results were compared to Brazil, state and city of Rio de Janeiro. ► The higher the environmental passive, the greater the possibility of use of biogas. - Abstract: This paper examines potential changes in solid waste policies for the reduction in GHG for the country of Brazil and one of its major states and cities, Rio de Janeiro, from 2005 to 2030. To examine these policy options, trends in solid waste quantities and associated GHG emissions are derived. Three alternative policy scenarios are evaluated in terms of effectiveness, technology, and economics and conclusions posited regarding optimal strategies for Brazil to implement. These scenarios are been building on the guidelines for national inventories of GHG emissions (IPCC, 2006) and adapted to Brazilian states and municipalities’ boundaries. Based on the results, it is possible to say that the potential revenue from products of solid waste management is more than sufficient to transform the current scenario in this country into one of financial and environmental gains, where the negative impacts of climate change have created a huge opportunity to expand infrastructure for waste management

    Abstract Chrysomelinae is one of the largest subfamilies in Chrysomelidae, yet much basic information remains unknown for Neotropical species. The present study aims to compile the first regional list of Chrysomelinae for the State of Rio de Janeiro, Brazil, and assemble natural history traits obtained from our fieldwork from 2005 to 2010 in Serra dos Órgãos National Park, a mountainous area of Atlantic forest. The species list was compiled from data from field work, collections, and literature, and recorded a total of 100 species, belonging to 21 genera in one tribe (Chrysomelini) and three subtribes: Chrysolinina (91 species), Chrysomelina (eight species) and Entomoscelina (one species). Of these, 91 species are new records for the state. Serra dos Órgaõs National Park holds records of 43 species, with Platyphora being the most species-rich genus, and Solanaceae the most common host plant family. Some new records of reproductive mode (larviparous vs. oviparous) and larval behavior are also given. These Brazil Chrysomelinae species exhibited a clear seasonal pattern, with more species recorded in the hot and rainy season from October to January, and considerably fewer species from June to August, during the drier and colder months. The fraction of new records in comparison with published species and natural history information illustrates how little we know of Chrysomelinae in the state and in the country. PMID:29391849

    Full Text Available A study of polychlorinated dibenzo-p-dioxins (PCDDs, polychlorinated dibenzofurans (PCDFs and polychlorinated biphenyls (dl-PCBs was conducted in a pooled sample of breast milk from 27 primiparous mothers living in 12 locations in the meso-region industrial area of southern Rio de Janeiro, Brazil, between August 2012 and July 2013. Questionnaires with questions regarding food habits, social and economic conditions and places of dwelling were applied. Milk was collected between four and six weeks after delivery from mothers were breast-feeding only one infant. The toxic equivalency (TEQ of PCDD/Fs, and dl-PCBs were 10.6, 4.77, 6.96 TEQ pg/g, respectively. The understanding and identification of pollution sources may be helpful for applying better counter measures against breast milk dioxin contamination. It is important for pregnant women to have a diet that is as free as possible from chemical contaminants. Further research must be undertaken in the context of epidemiological investigations to more accurately assess the effects of these compounds. The background contamination by PCDD/Fs, and dl-PCBs in mothers living at industrial area in Rio de Janeiro is lower than that generally found in industrialized countries.

    Full Text Available Climate variations and historical land use had a major impact on landscape development in the Brazilian Atlantic Forest (Mata Atlântica. In southeast Brazil, rainforest expanded under warm-humid climate conditions in the late Holocene, but have been dramatically reduced in historical times. Nevertheless, the numerous remaining forest fragments are of outstanding biological richness. In our research in the Atlantic Forest of Rio de Janeiro we aim at the reconstruction of the late Quaternary landscape evolution and an assessment of human impact on landscapes and rainforests. In this context, special focus is given on (a effects of climate variations on vegetation cover, soil development, and geomorphological processes, and (b spatial and temporal land use and landscape degradation patterns. In this paper we present some new results of our interdisciplinary research in the Serra dos Órgãos mountain range, state of Rio de Janeiro.

    To evaluate dentists' professional experience and knowledge of emergency management of tooth avulsion injuries in Rio de Janeiro, Brazil. A total of 100 questionnaires were evaluated. The first part of the questionnaire consisted of questions regarding personal information. The second part evaluated dentists' knowledge of emergency management in cases of dental avulsion. The responses for each question were counted and expressed as percentages. All dentists had a college degree or above. Only three dentists had a Master's or PhD degree. Most of the dentists (94.5%) considered time and storage media important for the prognosis of avulsed teeth. However, the dentists did not show consistent responses about the adequate time and ideal storage media to transport avulsed teeth. The study highlighted Brazilian dentists' need for continuing education in order to improve current knowledge in emergency management of avulsed teeth.

    The drug residues of lipid regulators, anti-inflammatories and some drug metabolites have been detected in raw sewage, treated waste water and river water in the state of Rio de Janeiro, Brazil. These residues are mainly derived from humans via excretion. The median concentrations in the effluents of sewage treatment plants (STPs) of most drugs investigated in this study ranged from 0.1 to 1 microgram/l. The removal rates of individual drugs during passage through a Brazilian STP varied from 12 to 90%. As a consequence of the incomplete removal of these residues during passage through a STP, rivers were also found to be contaminated. Median concentrations ranged from between 0.02 and 0.04 microgram/l in river water, whereas the maximum values were observed to be up to 0.5 microgram/l.

    Full Text Available Some of the most difficult and troubling problems encountered in construction are those caused by corrosive processes. The corrosion processes are constituted by some material degradation, generally metallic material, by means of chemical or electrochemical actions of environment in which the material are and can or cannot be combined with mechanical stress. Corrosion is present in the materials in general. Their deterioration is caused by such physical-chemical interaction between the material and the corrosive environment where it causes major problems in several activities. In order to prevent material losses, anticorrosive techniques are used which include coatings, medium modification techniques, anodic and cathodic protection, and corrosion inhibitors such as the organic compounds use. This article analyses the statistical study of corrosion types in construction in south region of Rio de Janeiro, Brazil.

    Full Text Available In Brazil, American visceral leishmaniasis (AVL is caused byLeishmania (Leishmania chagasi and its main vector isLutzomyia longipalpis. Cases of canine visceral leishmaniasis (CVL in non-endemic areas have been reported over the last few years throughout the country. The objective of this research note is to describe an autochthonous case of CVL that occurred in the municipality of Volta Redonda, state of Rio de Janeiro, an area where the disease is not endemic, alerting veterinarians and the scientific community to the expansion of this important zoonosis and advising veterinary practitioners on how to deal with a suspicion of CVL. Canine visceral leishmaniasis can be misdiagnosed within a broad spectrum of canine diseases based on clinical and laboratory findings. Therefore, knowledge of its clinical manifestations, specific and sensitive laboratory diagnostic tests and parasitological procedures are of the utmost importance for rapid confirmation and notification of a case, thus contributing directly to the control of a focus.

    Full Text Available The Atlantic Rain forest, which is considered the second largest pluvial forest in the American continent, has had an estimated 93% of its original area destroyed. Although studies concerning the herpetofaunal diversity in this biome have been intensified in the past years, its diversity is still underestimated. The Nucleo Experimental de Iguaba Grande (NEIG is included in an Environmental Protection Area (APA de Sapeatiba in the Iguaba Grande municipality, Rio de Janeiro state, Brazil (22º 51' S and 42º 10' W. The goal of this study was to conduct an inventory of the reptile and amphibian species that occur in this area between July 2008 and December 2009. We recorded 19 species of amphibians (18 anurans and one caecilian and 15 species of reptiles (three lizards, 11 snakes and one amphisbaenian. Leptodactylus latrans and L. mystacinus had the highest capture rates among amphibians captured, and among reptiles, Ameiva ameiva, Hemidactylus mabouia and Mabuya agilis had the highest capture rates. Rarefaction curves for both amphibians and reptiles did not reach the asymptote, indicating that the species richness in the NEIG is still underestimated.

    Full Text Available Pharmaceuticals are considered to be important environmental contaminants. The aim of this study was to evaluate their presence in water intended for public supply to Municipally of Rio de Janeiro, Brazil. The regional environmental assessment was done from the analysis of surface water and distribution for the presence of psychiatric drugs. The study reveals the presence of benzodiazepine derivatives in all samples of surface water samples of the Guandu River, with the amounts of 42 ng L-1, 198 ng L-1 and 335 ng L-1 for bromazepam, clonazepam, and diazepam, respectively. The population served by Companhia Estadual de Águas e Esgotos (CEDAE is the order of ten million. Psychiatric pharmaceuticals, in particular, are thought to impose significant ecological risks. A better understanding of the real impact of these pollutants implies a comprehensive evaluation of their persistence and fate in environmental matrices. The studies presented in this article are intended to contribute to improve the knowledge about the occurrence of some psychiatric drugs in the water supply.

    Cannabis sativa, known by the common name marijuana, is the psychoactive drug most widely distributed in the world. Identification of Cannabis cultivars may be useful for association to illegal crops, which may reveal trafficking routes and related criminal groups. This study provides evidence for the performance of a segment of the rbcL gene, through genetic signature, as a tool for identification for C. sativa samples apprehended by the Rio de Janeiro Police, Brazil. The PCR amplified and further sequenced the fragment of approximately 561 bp of 24 samples of C. sativa rbcL gene and showed the same nucleotide sequences, suggesting a possible genetic similarity or identical varieties. Comparing with other Cannabaceae family sequences, we have found 99% of similarity between the Rio de Janeiro sequence and three other C. sativa rbcL genes. These findings suggest that the fragment utilized at this study is efficient in identifying C. sativa samples, therefore, useful in genetic discrimination of samples seized in forensic cases.

    One of the main concerns of contemporary society regarding prevailing climate change is related to possible changes in the frequency and intensity of extreme events. Strong heat and cold waves, droughts, severe floods, and other climatic extremes have been of great interest to researchers because of its huge impact on the environment and population, causing high monetary damages and, in some cases, loss of life. The frequency and intensity of extreme events associated with precipitation and air temperature have been increased in several regions of the planet in recent years. These changes produce serious impacts on human activities such as agriculture, health, urban planning and development and management of water resources. In this paper, we analyze the trends in indices of climatic extremes related to daily precipitation and maximum and minimum temperatures at 22 meteorological stations of the National Institute of Meteorology (INMET) in Rio de Janeiro State (Brazil) in the last 50 years. The present trends are evaluated using the software RClimdex (Canadian Meteorological Service) and are also subjected to statistical tests. Preliminary results indicate that periods of drought are getting longer in Rio de Janeiro State, except in the North/Northwest area. In "Vale do Paraíba", "Região Serrana" and "Região dos Lagos" the increase of consecutive dry days is statistically significant. However, we also detected an increase in the total annual rainfall all over the State (taxes varying from +2 to +8 mm/year), which are statistically significant at "Região Serrana". Moreover, the intensity of heavy rainfall is also growing in most of Rio de Janeiro, except in "Costa Verde". The trends of heavy rainfall indices show significant increase in the "Metropolitan Region" and in "Região Serrana", factor that increases the vulnerability to natural disasters in these areas. With respect to temperature, it is found that the frequency of hot (cold) days and nights is

    To determine the mortality rate of children, adolescents and adults with sickle cell anemia in Rio de Janeiro, Brazil. The number of deaths, the mortality rate and the causes of deaths in patients with sickle cell anemia who were treated and followed up at our institution for 15 years were determined and compared to data available for the Brazilian population. The overall number of deaths was 281 patients with a mortality rate of 16.77%. Survival probability was significantly higher in females. The number of deaths and the mortality rate were age-specific with a significant increase in the 19- to 29-year-old age group. The remaining life expectancy of the patients with sickle cell anemia was less than that of Brazilians at large. The gap between the two was about 20 years for ages between one and five years with this gap decreasing to ten years after the age of 65 years. The most common causes of death were infection, acute chest syndrome, overt stroke, organ damage and sudden death during painful crises. To the best of our knowledge, this is the first Brazilian study in a single institution in Rio de Janeiro; the mortality rate was 18.87% among adult patients with sickle cell anemia. The mortality rates in children and adults are higher than those reported in developed countries of the northern hemisphere.

    Full Text Available Rio de Janeiro, Brazil, experienced a severe dengue fever epidemic in 2008. This was the worst epidemic ever, characterized by a sharp increase in case-fatality rate, mainly among younger individuals. A combination of factors, such as climate, mosquito abundance, buildup of the susceptible population, or viral evolution, could explain the severity of this epidemic. The main objective of this study is to model the spatial patterns of dengue seroprevalence in three neighborhoods with different socioeconomic profiles in Rio de Janeiro. As blood sampling coincided with the peak of dengue transmission, we were also able to identify recent dengue infections and visually relate them to Aedes aegypti spatial distribution abundance. We analyzed individual and spatial factors associated with seroprevalence using Generalized Additive Model (GAM.Three neighborhoods were investigated: a central urban neighborhood, and two isolated areas characterized as a slum and a suburban area. Weekly mosquito collections started in September 2006 and continued until March 2008. In each study area, 40 adult traps and 40 egg traps were installed in a random sample of premises, and two infestation indexes calculated: mean adult density and mean egg density. Sera from individuals living in the three neighborhoods were collected before the 2008 epidemic (July through November 2007 and during the epidemic (February through April 2008. Sera were tested for DENV-reactive IgM, IgG, Nested RT-PCR, and Real Time RT-PCR. From the before-after epidemics paired data, we described seroprevalence, recent dengue infections (asymptomatic or not, and seroconversion. Recent dengue infection varied from 1.3% to 14.1% among study areas. The highest IgM seropositivity occurred in the slum, where mosquito abundance was the lowest, but household conditions were the best for promoting contact between hosts and vectors. By fitting spatial GAM we found dengue seroprevalence hotspots located at the

    The induction of cytochrome P4501A-mediated activity (e.g. ethoxyresorufin-O-deethylation, EROD) has been used as a biomarker for monitoring fish exposure to AhR-receptor ligands such as polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB) and polychlorinated dibenzo-dioxins/furans (PCDD/Fs). In this study we found that hepatic EROD is induced in fish ("Nile tilapia", Oreochromis niloticus and "acará", Geophagus brasiliensis) from the Guandu River (7-17-fold) and Jacarepaguá Lake (7-fold), Rio de Janeiro, Brazil. Since both cichlid fish are consumed by the local population and the Guandu River is the main source of the drinking water supply for the greater Rio de Janeiro metropolitan area, pollution by cytochrome P4501A-inducing chemicals is a cause for concern and should be further investigated in sediments, water and biota. We additionally showed that EROD activity in the fish liver post-mitochondrial supernatant-simpler, cheaper and less time consuming to prepare than the microsomal fraction-is sufficiently sensitive for monitoring purposes.

    Intestinal parasitic infections are considered a serious public health problem and widely distributed worldwide, mainly in urban and rural environments of tropical and subtropical countries. Globally, soil-transmitted helminths and protozoa are the most common intestinal parasites. Blastocystis sp. is a highly prevalent suspected pathogenic protozoan, and considered an unusual protist due to its significant genetic diversity and host plasticity. A total of 294 stool samples were collected from inhabitants of three rural valleys in Rio de Janeiro, Brazil. The stool samples were evaluated by parasitological methods, fecal culture, nested PCR and PCR/Sequencing. Overall prevalence by parasitological analyses was 64.3% (189 out of 294 cases). Blastocystis sp. (55.8%) was the most prevalent, followed by Endolimax nana (18.7%), Entamoeba histolytica complex (7.1%), hookworm infection (7.1%), Entomoeba coli (5.8%), Giardia intestinalis (4.1%), Iodamoeba butchilii (1.0%), Trichuris trichiura (1.0%), Pentatrichomonas hominis (0.7%), Enterobius vermicularis (0.7%), Ascaris lumbricoides (0.7%) and Strongyloides stercoralis (0.7%). Prevalence of IPIs was significantly different by gender. Phylogenetic analysis of Blastocystis sp. and BLAST search revealed five different subtypes: ST3 (34.0%), ST1 (27.0%), ST2 (27.0%), ST4 (3.5%), ST8 (7.0%) and a non-identified subtype. Our findings demonstrate that intestinal parasite infection rates in rural areas of the Sumidouro municipality of Rio de Janeiro, Brazil are still high and remain a challenge to public health. Moreover, our data reveals significant genetic heterogeneity of Blastocystis sp. subtypes and a possible novel subtype, whose confirmation will require additional data. Our study contributes to the understanding of potential routes of transmission, epidemiology, and genetic diversity of Blastocystis sp. in rural areas both at a regional and global scale.

    We propose the use of previously developed small area estimation techniques to monitor obesity and dietary habits in developing countries and apply the model to Rio de Janeiro city. We estimate obesity prevalence rates at the Census Tract through a combinatorial optimization spatial microsimulation model that matches body mass index and socio-demographic data in Brazil's 2008-9 family expenditure survey with Census 2010 socio-demographic data. Obesity ranges from 8% to 25% in most areas and affects the poor almost as much as the rich. Male and female obesity rates are uncorrelated at the small area level. The model is an effective tool to understand the complexity of the problem and to aid in policy design. © 2013 Published by Elsevier Ltd.

    Ninety-two surface sediment samples were collected in Guanabara Bay, one of the most prominent urban bays in SE Brazil, to investigate the spatial distribution of anthropogenic pollutants. The concentrations of heavy metals, organic carbon and particle size were examined in all samples. Large spatial variations of heavy metals and particle size were observed. The highest concentrations of heavy metals were found in the muddy sediments from the north western region of the bay near the main outlets of the most polluted rivers, municipal waste drainage systems and one of the major oil refineries. Another anomalous concentration of metals was found adjacent to Rio de Janeiro Harbour. The heavy metal concentrations decrease to the northeast, due to intact rivers and the mangrove systems in this area, and to the south where the sand fraction and open-marine processes dominate. The geochemical normalization of metal data to Li or Al has also demonstrated that the anthropogenic input of heavy metals have altered the natural sediment heavy metal distribution.

    The offshore oil industry is characterized by complex systems in relation to technology and organization of work. Working conditions are hazardous, resulting in accidents and even occasional full-scale catastrophes. This article is the result of a study on work-related accidents in the offshore platforms in the Campos Basin, Rio de Janeiro State. The primary objective was to provide technical back-up for both workers' representative organizations and public authorities. As a methodology, we attempt to go beyond the immediate causes of accidents and emphasize underlying causes related to organizational and managerial aspects. The sources were used in such a way as to permit classification in relation to the type of incident, technological system, operation, and immediate and underlying causes. The results show the aggravation of safety conditions and the immediate need for public authorities and the offshore oil industry in Brazil to change the methods used to investigate accidents in order to identify the main causes in the organizational and managerial structure of companies.

    SUMMARY The aim of the present study was to analyze the status of the American Tegumentary Leishmaniasis (ATL) in the state of Rio de Janeiro, from 2004 to 2013, through its spatiotemporal distribution. We also described variables considered relevant to the epidemiology of the disease, such as the clinical form, gender, ethnic group, age group, and progression of disease. This is a descriptive study, which used notified secondary data from the Brazilian Information System of Notifiable Diseases (SINAN), Ministry of Health, Brazil, regarding confirmed diagnoses. To help the calculation of coefficients of detection and mortality, we used population data from the Brazilian Institute of Geography and Statistics (IBGE). We analyzed 1,470 cases of ATL with the predominance of the cutaneous clinical form (1,292/87.89%). The data has also revealed seven deaths, a predominance of males (922/62.72%), and a higher incidence of ATL in the white ethnic group (731/49.72%). We observed a high incidence of ATL in the group of 20 - 39 years old (477/32.44%). We concluded that there was a decrease in the number of ATL cases in the state of Rio de Janeiro, based on a coefficient of detection of 1.44/100.000 inhabitants in 2004 decreasing to 0.20/100.000 inhabitants in 2013. The localities with the highest occurrences of ATL were the metropolitan region (843 cases) and the municipality of Rio de Janeiro (740 cases). In 2005, the highest incidence of the disease was observed (351 cases) in the study. Among the variables selected to describe the epidemiology of the disease, the following categories: cutaneous clinical form, male patients, white ethnic group, and the age group of 20 - 39 years old were more affected than the others.

E-mail: nathaliecunha@id.uff.br Toxoplasmosis is a serious public health problem worldwide as it can cause prenatal and neonatal morbidity and mortality in humans. Although dogs are not definitive hosts of T. gondii, they play an important role in the mechanical dissemination of oocysts. This study aimed to carry out a seroepidemiological investigation of anti-Toxoplasma gondii antibodies in domestic dogs from seven municipalities in the state of Rio de Janeiro, Brazil. A crosssectional epidemiological study was carried out to evaluate the profile of anti-Toxoplasma gondii IgG antibodies in dogs from canine sera from different municipalities in the state of Rio de Janeiro. The municipalities studied were Cachoeiras de Macacu, Guapimirim, Itaboraí, Magé, Resende, Seropédica and Silva Jardim. The detection of antibodies of the IgG class anti-Toxoplasma gondii was performed using the indirect enzyme immunoadsorption (ELISA assay and the statistical analyzes used were the chi-square test and the prevalence ratio. Of the 651 samples tested, 300 were reactive for T. gondii, representing a relative frequency of 46.08% of seroreactive dogs. It was concluded that dogs are good sentinels for evaluations of risk for occurrence of T. gondii, emphasizing those coming from rural areas and that there was no difference in the occurrence of serorreative dogs in front of different municipalities studies of the state of Rio de Janeiro.

    In the first half of 2014, 6,675 adults and caregivers of children using Primary Care (PC) services in Rio de Janeiro were interviewed using the Primary Care Assessment Tool - PCATool-Brazil. The aim was to arrive at an accurate overview of the extent to which PC services in all of the Planning Areas (PA) of the Rio de Janeiro City Health Department (CHD) - Municipal Health Secretariat have the essential and derivative attributes. This was a cross-sectional study of random, independent samples of the service users (children and adults). Results were measured using the scores assigned to PC attributes. In the opinion of adults and children using PC services, Type A Units - Municipal Healthcare Centers and Family Clinics staffed only with Family Health Teams, performed better than Type B units. The scores for the attributes "first contact accessibility", "comprehensive service - services provided", "community orientation" and "family orientation" still need to be improved. On the other hand "coordinated care" and "continuity" are on their way to quality scores, being always rated at around 6.0 or even higher.

    Full Text Available Agriculture in the mountain region of Rio de Janeiro State is characterized by intensive soil use and input. Such mountainous environments are vulnerable to climate events; thus, the current article presents a report on methods applied to exchange academic and traditional knowledge. The aim is to expand farmers’ perception about the need of implementing agro-ecological practices, mainly soil management practices, which are important for agricultural sustainability in mountainous environments. The study was conducted in a Nova Friburgo family production unit, in the mountain region of Rio de Janeiro State (Brazil. It consisted of implementing three observation and soil organic-matter management units. The idea was to reduce the incidence of clubroot of crucifers disease caused by Plasmidiophora brassicae. The soil fauna was discussed with local farmers, with emphasis on the association between ecological processes and soil management. The present study improved the discussion with farmers and the need of introducing other innovative conservation practices such as no-tillage system and participatory research based on agro-ecological propositions.

E-mail: carolinespitz@yahoo.com.br The parabasalid flagellate Tritrichomonas foetus is recognized as the causative agent of large bowel diarrhea in domestic cats. A second species of parabasalid flagellate Pentatrichomonas hominis, has also been reported in association with domestic cats, albeit almost exclusively as a commensal organism. However, there is growing evidence to suggest that P. hominis may also be involved in feline gastro-intestinal disorders including diarrhea and that the incidence of infection with P. hominis may have been underestimated due to it being misidentified as T. foetus. The aim of the current study was to establish the basis for routine morphological identification of P. hominis employing light microscopy and to apply the methodology to the examination of cases of diarrhea in a laboratory population of Brazilian domestic cats (n =39. A detailed morphological description of P. hominis isolated from 11 cats with diarrhea was produced and molecular analyses were performed in support of the morphological data and to demonstrate the absence of T. foetus in infected cats. All animals with diarrhea were demonstrated to be infected solely with P. hominis. The findings of the current study provide a straight forward and validated method for the differential diagnosis of P. hominis and contribute to the on-going debate surrounding the pathogenic potential of this parabasalid flagellate.

    Full Text Available INTRODUCTION: Strongyloides stercoralis is a soil-transmitted helminth that produces an infection that can persist for decades. The relationships between certain clinical conditions and strongyloidiasis remains controversial. This study aims to identify the clinical conditions associated with intestinal strongyloidiasis at a reference center for infectious diseases in Rio de Janeiro, Brazil. METHODS: The clinical conditions that were assessed included HIV/AIDS, HTLV infection, cardiovascular diseases, diabetes, obstructive respiratory diseases, viral hepatitis, tuberculosis, cancer, chronic renal disease, nutritional/metabolic disorders, psychiatric conditions, rheumatic diseases and dermatologic diseases. We compared 167 S. stercoralis-positive and 133 S. stercoralis-negative patients. RESULTS: After controlling for sex (male/female OR = 2.29; 95% (CI: (1.42 - 3.70, rheumatic diseases remained significantly associated with intestinal strongyloidiasis (OR: 4.96; 95% CI: 1.34-18.37 in a multiple logistic regression model. With respect to leukocyte counts, patients with strongyloidiasis presented with significantly higher relative eosinophil (10.32% ± 7.2 vs. 4.23% ± 2.92 and monocyte (8.49% ± 7.25 vs. 5.39% ± 4.31 counts and lower segmented neutrophil (52.85% ± 15.31 vs. 61.32% ± 11.4 and lymphocyte counts (28.11% ± 9.72 vs. 30.90% ± 9.51 than S. stercoralis-negative patients. CONCLUSIONS: Strongyloidiasis should be routinely investigated in hospitalized patients with complex conditions facilitate the treatment of patients who will undergo immunosuppressive therapy. Diagnoses should be determined through the use of appropriate parasitological methods, such as the Baermann-Moraes technique.

  6. Diagnosis of Alzheimer's disease in Brazil: Supplementary exams

    Directory of Open Access Journals (Sweden)

    Paulo Caramelli

    Full Text Available Abstract This article presents a review of the recommendations on supplementary exams employed for the clinical diagnosis of Alzheimer's disease (AD in Brazil published in 2005. A systematic assessment of the consensus reached in other countries, and of articles on AD diagnosis in Brazil available on the PUBMED and LILACS medical databases, was carried out. Recommended laboratory exams included complete blood count, serum creatinine, thyroid stimulating hormone (TSH, albumin, hepatic enzymes, Vitamin B12, folic acid, calcium, serological reactions for syphilis and serology for HIV in patients aged younger than 60 years with atypical clinical signs or suggestive symptoms. Structural neuroimaging, computed tomography or - preferably - magnetic resonance exams, are indicated for diagnostic investigation of dementia syndrome to rule out secondary etiologies. Functional neuroimaging exams (SPECT and PET, when available, increase diagnostic reliability and assist in the differential diagnosis of other types of dementia. The cerebrospinal fluid exam is indicated in cases of pre-senile onset dementia with atypical clinical presentation or course, for communicant hydrocephaly, and suspected inflammatory, infectious or prion disease of the central nervous system. Routine electroencephalograms aid the differential diagnosis of dementia syndrome with other conditions which impair cognitive functioning. Genotyping of apolipoprotein E or other susceptibility polymorphisms is not recommended for diagnostic purposes or for assessing the risk of developing the disease. Biomarkers related to the molecular alterations in AD are largely limited to use exclusively in research protocols, but when available can contribute to improving the accuracy of diagnosis of the disease.

    Full Text Available Echovirus 30 belongs to the genus Enterovirus and is widely associated with aseptic meningitis (AM outbreaks. In Brazil epidemics due to this serotype were reported in several states but in Rio de Janeiro, before this study, it was only involved in sporadic episodes. We retrospectively collected data from AM notifications charts and enterovirus isolation database from Rio de Janeiro State Health Department (RJSHD and Enterovirus Reference Laboratory in the year of 2005. An outbreak of AM was detected during March, April and May associated with a high cell culture isolation rate for echovirus 30 (17.4%. Male children with ages varying from 1 to 9 years were more affected. Of the 22 patients with confirmed echovirus 30 disease, clinical information was available in eight; fever, headache and vomiting were the most common manifestations. CSF analysis showed a typical pattern of viral infection with median of cellularity of 100 cells/mm³ and mononuclear cell predominance in 64.7% of the cases. The median of protein and glucose levels of 49 mg/dL and 56.5 mg/dL. The fatality rate was null. Despite its benign course and the lack of treatment options, aseptic meningitis surveillance is crucial for early identification of causative agents of outbreaks, which helps to avoid additional testing and inappropriate use of antimicrobials.

    Rodrigo Garcia Alvim

    Full Text Available ABSTRACT: Aleurocanthus woglumi is an exotic pest, widely disseminated in Brazil, with a high preference for citrus plants, but with a polyphagous feeding habit. The contribution of the state of Rio de Janeiro in the Brazilian production of citrus fruits is small; however, there are still public policies that encourage citrus production in the state. In 2010, the appearance of this pest in Rio de Janeiro was confirmed in the municipality of Cachoeiras de Macacu. The objectives of this research were to evaluate the dissemination of A. woglumi in this state, conduct a survey of new species of host plants, identify and evaluate the population of natural enemies present at two orchards that grow 'Tahiti' limes ( Citrus latifolia infested by the pest in Cachoeiras de Macacu, RJ, Brazil. In 19 municipalities, leaves of citrus and other species of plants presenting aleyrodid nymphs were collected, and yellow sticky traps were installed to capture adults for subsequent identification. At the 'Tahiti' lime orchards, the leaf collections were done to confirm the species of Aleyrodidae , and regarding A. woglumi , the natural enemies associated with this pest were collected directly from the infested plants. The results showed that A. woglumi is wide-spread in 12 municipalities. Three new host plants for A. woglumi were identified: Artocarpus heterophyllus ( Moraceae , Pouteria caimito ( Sapotaceae and Struthanthus flexicaulis ( Loranthaceae . In Cachoeiras de Macacu, a new species of parasitoid of A. woglumi nymphs was named: Encarsia pergandiella (Hymenoptera: Aphelinidae , while the insects in the Coccinellidae (Coleoptera family have stood out as predators of this pest.

    The Accelerator Mass Spectrometry (AMS) technique is a very attractive method for mass spectrometry, since it allows determination of concentrations with sensitivity down to 1 atom of isotope in 1015 atoms, using few milligrams samples. A Tandem accelerator is used as a magnetic and electrostatic analyzer. The determination of these extremely low concentrations of rare isotopes, accelerated to the MeV range, is measured by the direct counting of the atoms by nuclear detection techniques. The AMS technique has been implemented recently in Brazil, at the Pelletron 8UD Tandem accelerator (Sao Paulo), following many improvements on the ion source, VGM control, machine parameters control and detection system. In this contribution we report an important application on AMS on archaeological studies, performed at the Prime Lab (USA), on the dating of ceramics, bones, charcoals, nuts and shells samples of the of the coast of Rio de Janeiro. The main objective of this work is to improve the present knowledge on the occupation of Brazil by the Indians in the prehistoric period, studying archaeological sites located in Rio de Janeiro. Studies show that the Brazilian coast was first occupied in the beginning of the Holocene, with the settlements of the collectors of mollusk, builders of shell mounds, called S ambaquis . The word is of Tupi etymology, tamba meaning shellfish and ki to pile up. The Tupi were a horticultural/potter group who used to live on the Brazilian coast at the time of the European arrivals; they coined the term that describes the main characteristic of the sites - the accumulation of great quantities of mollusk shells. One of objectives of this research is to understand those societies functioning structure, spatial ordering, interaction in the environment and their transformation processes, from the study of their remains. It is intended to analyze the region occupation process dynamics and search for possible links between the pre-pottery population socio

    Full Text Available SUMMARY American tegumentary leishmaniasis (ATL is an infectious disease caused by protozoa of the genus Leishmania, and transmitted by sandflies. In the state of Rio de Janeiro, almost all of the cases of American tegumentary leishmaniasis (ATL are caused by Leishmania (Viannia braziliensis, while cases of visceral leishmaniasis (VL are caused by Leishmania (Leishmania infantum chagasi. The resurgence of autochthonous VL cases in Rio de Janeiro is related to the geographic expansion of the vector Lutzomyia longipalpis and its ability to adapt to urban areas. We report the first case of leishmaniasis with exclusively cutaneous manifestations caused by L. (L. infantum chagasi in an urban area of Rio de Janeiro. An eighty-one-year-old woman presented three pleomorphic skin lesions that were not associated with systemic symptoms or visceromegalies. Multilocus enzyme electrophoresis identified L. (L. infantum chagasi, but direct smear and PCR of bone narrow were negative for Leishmania sp. (suggesting exclusively cutaneous involvement. We discuss the different dermatological presentations of viscerotropic leishmaniasis of the New and Old World, and the clinical and epidemiological importance of the case. Etiologic diagnosis of ATL based upon exclusive clinical criteria may lead to incorrect conclusions. We should be aware of the constant changes in epidemiological patterns related to leishmaniases.

    Amblyomma rotundatum Koch is a parthenogenetic tick usually associated with reptiles and amphibians. However, relatively few studies on occurrences of ticks in wild reptile populations in Brazil have been produced. The aim of this study was to analyze the presence of ticks associated with reptile species in the Grussaí restinga, in the municipality of São João da Barra, state of Rio de Janeiro, Brazil. Between December 2010 and January 2011, 131 individuals belonging to nine species of reptiles of the order Squamata were sampled: the lizards Tropidurus torquatus (n = 51), Hemidactylus mabouia (n = 25), Mabuya agilis (n = 30), Mabuya macrorhyncha (n = 6), Cnemidophorus littoralis (n = 5) and Ameiva ameiva (n = 10); and the snakes Philodryas olfersii (n = 2), Oxyrhopus rhombifer (n = 1) and Micrurus corallinus (n = 1). The only tick species found to be associated with any of the reptiles sampled was A. rotundatum. One adult female was detected on one individual of the lizard A. ameiva, one nymph on one individual of the lizard T. torquatus and four nymphs on one individual of the snake P. olfersii. This study is the first record of parasitism of A. rotundatum involving the reptiles T. torquatus and P. olfersii as hosts. Our results suggest that in the Grussaí restinga habitat, A. rotundatum may use different species of reptiles to complete its life cycle.

    Full Text Available Samples of liver and kidney of Kelp gull (Larus dominicanus collected on Sepetiba Bay, Rio de Janeiro, Brazil, were analysed for their copper, zinc, cadmium, lead, chromium and nickel content. All the analyses were made using the inductively coupled plasma optical spectrometry method (ICP-OES. The investigation focused on the variability of the elements content in kidney and liver from a number of sampling seabirds and over different seasons. The results were interpreted using the analysis of variance test (ANOVA. This has revealed differences in concentration for the majority of elements with regard to organs, and how different sampling metals and organs are related to each other. Results indicate relatively high trace etalcontamination in L. dominicanus, showing potential power of idespread biological and mutagenic adverse effects in trophic levels, and herefore, signalling risk to human health.

    This study aimed to assess the microbiological contamination of lettuces commercialized in Rio de Janeiro, Brazil, in order to investigate detection of norovirus genogroup II (NoV GII), Salmonella spp., total and fecal coliforms, such as Escherichia coli. For NoV detection samples were processed using the adsorption-elution concentration method associated to real-time quantitative polymerase chain reaction (qPCR). A total of 90 samples of lettuce including 30 whole fresh lettuces, 30 minimally processed (MP) lettuces, and 30 raw ready-to-eat (RTE) lettuce salads were randomly collected from different supermarkets (fresh and MP lettuce samples), food services, and self-service restaurants (RTE lettuce salads), all located in Rio de Janeiro, Brazil, from October 2010 to December 2011. NoV GII was not detected and PP7 bacteriophage used as internal control process (ICP) was recovered in 40.0%, 86.7%, and 76.7% of those samples, respectively. Salmonella spp. was not detected although fecal contamination has been observed by fecal coliform concentrations higher than 10(2) most probable number/g. E. coli was detected in 70.0%, 6.7%, and 30.0% of fresh, MP, and RTE samples, respectively. This study highlights the need to improve hygiene procedures at all stages of vegetable production and to show PP7 bacteriophage as an ICP for recovering RNA viruses' methods from MP and RTE lettuce samples, encouraging the evaluation of new protocols that facilitate the establishment of methodologies for NoV detection in a greater number of food microbiology laboratories. The PP7 bacteriophage can be used as an internal control process in methods for recovering RNA viruses from minimally processed and ready-to-eat lettuce samples. © 2014 Institute of Food Technologists®

    Due to the populations' susceptibility, DENV-4 introduction in 2010 led to the occurrence of explosive epidemics in the following years in Brazil. In 2011, DENV-4 was identified in Rio de Janeiro (RJ) and it was prevalent in 2012 and 2013. Here, we aimed to characterize clinical, epidemiological and laboratorial aspects of DENV-4 cases after this serotype introduction in an endemic scenario. Dengue suspected cases (n = 3727) were received and analyzed from January 2011 to December 2013, during outbreaks occurred in RJ, Brazil. Samples were submitted to virological, serological and molecular methods for case confirmation. DENV-4 cases (n = 705) were characterized according to the type of infection, disease severity and, viremia levels and NS1 antigenemia were accessed. Representative strains were partial sequenced for genotyping. DENV-4 was identified in 44.2% (705/1593) of dengue positive cases, virus isolated in 48.7% of the cases. Anti-DENV IgM was detected in 39.4% of the cases, however an increased detection was observed in cases with ≥4 days of symptoms (57.0%). NS1 antigen was identified in 41.5% of DENV-4 cases however, after immune complexes dissociation, the detection significantly increased (87.6%). Females were more affected than males, so did children aged 11-15 years old. Primary cases were more frequently observed than secondary ones and most of them were classified as dengue. No differences on NS1 antigenemia and viraemia within the groups were observed. Despite the higher frequency of severe disease on individuals >65 years old, no differences were observed among the groups and type of infection. However, DENV-4 fatal cases were more frequent on secondary infections (57.1%). DENV-4 Genotype II was identified with a probable origin from Venezuela and Colombia. It has been shown that laboratorial diagnosis is still a reliable tool for the disease surveillance, detecting and confirming emerging epidemics. Despite the occurrence of secondary

    This study aimed to identify factors associated with the health care of patients with HIV/AIDS who drop out. The study was developed in a specialized health care unit of a University hospital in Rio de Janeiro, Brazil, considering a stratified sample of adult patients including all dropout cases (155) and 44.0% of 790 cases under regular follow-up. Bivariate analyses were used to identify associations between health care dropout and demographic, socioeconomic and clinical variables. Logistic and Cox regression models were used to identify the independent effects of the explanatory variables on risk for dropout, in the latter by incorporating information on the outcome over time. Patients were, on average, 35 years old, predominantly males (66.4%) and of a low socioeconomic level (45.0%). In both models, health care dropout was consistently associated with being unemployed or having an unstable job, using illicit drugs and having psychiatric background--positive association; and with age, having AIDS, and having used multiple antiretroviral regimens--negative association. In the logistic regression, dropping out was also positively associated with time between diagnosis and the first outpatient visit, while in the Cox model, the hazard for dropping out was positively associated with being single, and negatively associated with a higher educational level. The results of this work allow for the identification of HIV/AIDS patients more likely to drop out from health care.

    In this article, we outline the discussions about the mechanisms of governance and public administration taking into account the main political and economic schools of thought which affect the decisions taken by elected and public bodies. We discuss the pendulum-style approach of the reforms and the degree of minimization of the Weberian thesis on rational bureaucracy. Taking into account conceptual aspects and the trajectory of the debate on a new form of public governance and the 1995 State of Brazil reforms, we analyzed the institutional design of the Municipal Health Secretariat in Rio de Janeiro after the reforms were adopted, based on a social organizational model. We also took into account regulatory capacity and the sustainability of the governmental schools.

    Full Text Available This research aimed to describe the frequency of parasites in stool samples in the environment of Ilha da Marambaia, Rio de Janeiro, Brazil. One hundred and five stool samples were collected and processed by the coproparasitological techniques ethyl acetate sedimentation and centrifuge-flotation using saturated sugar solution. Parasites were detected in 81.9% of the samples, hookworm being the most prevalent, followed by Trichuris vulpis. Ascaris sp. eggs were also found. A high level of evolutive forms of parasites with public health risk was found in stool samples of the environment studied. We propose that health education programs, allied to an improvement of human and animal health care, must be employed to reduce the environmental contamination.

    On January, 2011, a devastating tropical storm hit the mountain area of Rio de Janeiro State in Brazil, resulting in flooding and mudslides and leaving 30,000 individuals displaced. This article explores key lessons learned from this major mass casualty event, highlighting prehospital and hospital organization for receiving multiple victims in a short period of time, which may be applicable in similar future events worldwide. A retrospective review of local hospital medical/fire department records and data from the Health and Security Department of the State were analyzed. Medical examiner archives were analyzed to determine the causes of death. The most common injuries were to the extremities, the majority requiring only wound cleaning, debridement, and suture. Orthopedic surgeries were the most common operative procedures. In the first 3 days, 191 victims underwent triage at the hospital with 50 requiring admission to the hospital. Two hundred fifty patients were triaged at the hospital by the end of the fifth day. The mortis cause for the majority of deaths was asphyxia, either by drowning or mud burial. Natural disasters are able to generate a large number of victims and overwhelm the main channels of relief available. Main lessons learned are as follows: 1) prevention and training are key points, 2) key measures by the authorities should be taken as early as possible, and 3) the centralization of the deceased in one location demonstrated greater effectiveness identifying victims and releasing the bodies back to families.

    As a consequence of the importance of ticks in forests in protected areas, was conducted survey of species of free-living ticks in the Natural Park Municipal Curió, state of Rio de Janeiro, Brazil. Monthly samples were taken by dragging method, dry ice traps and visual search in two transects. Adults and nymphs of Amblyomma cajennense (n= 147), Amblyomma brasiliense (n= 4) and Amblyomma parvum (n= 1) were collected. This is the first occurrence of A. parvum in the state. No correlation was found between the abundance of stages of A. cajennense and rainfall, temperature and relative humidity. The highest abundances of adults were in the months of January and May, and nymphs in September and October. The low diversity of parasites on Curió Park can be attributed to the proximity of households with pets, which would also explain the higher abundance of A. cajennense that is commonly found in areas impacted by anthropogenic pressure.

    In this study, twenty samples of clay smoking pipes excavated in an 18 km2 area between the Macacu and Caceribu rivers, in the municipality of Itaboraí, Rio de Janeiro, Brazil were analyzed by FT-IR technique. The samples, excavated in different archeological sites of the region, are dated between the seventeenth and the nineteenth centuries and are part of the material culture left by Africans and African descendants that lived in the complex. FT-IR analyses and complementary SEM-EDS studies showed that the clay paste used in the manufacture of smoking pipes, mostly handcrafted, is composed of quartz, feldspar, phyllosilicates and iron oxides. Multivariate statistical tests (PCA) were applied to FT-IR data to assess the interactions between the archeological sites. The results indicated that one archeological site - Macacu IV - is greatly related to the other sites. The results obtained have helped archeologists and anthropologists in better understanding the manufacturing process employed in ancient ceramic artifacts produced during the period of colonial Brazil.

    Full Text Available The author analyzes medical slang in Rio de Janeiro based on the view of interactive or live metaphor proposed by such authors as Black and Ricoeur, applied to puns and other jokes from medical work, with the goal of unveiling what physicians mean by this linguistic register. The article classifies medical slang in three broad areas, pertaining to the physician's relations with professional training and knowledge, patients, and health care services. Comparing his empirical material with previous studies focusing on hospital slang for patients, the author identifies, in addition, a range of slang terms for health care services themselves. The article points to interfaces between medical slang and the Brazilian "health hypercrisis" identified by Schramm.

Brazil is the seventh country with the highest rate of mercury in the atmosphere. The major input of Hg to ecosystems is through atmospheric deposition (wet and dry), being transported in the atmosphere over large distances. The forest biomes are of strong importance in the atmosphere/soil cycling of elemental Hg through foliar uptake and subsequent transference to the soil through litter, playing an important role as sink of this element. Soil microarthropods are keys to understanding the soil ecosystem, and for such purpose were characterized by the soil fauna of two Units of Forest Conservation of the state of the Rio de Janeiro, inwhich one of the areas suffer quite interference from petrochemicals and industrial anthropogenic activities and other area almost exempts of these perturbations. The results showed that soil and litter of the Atlantic Forest in Brazil tend to stock high mercury concentrations, which could affect the abundance and richness of soil fauna, endangering its biodiversity and thereby the functioning of ecosystems.

  10. Pacifying the Empire of Love: Sport, Spectacle, Security in Rio de Janeiro

    Richard Benjamin Penglase

    2016-06-01

    Full Text Available This essay examines the confluence of sport, spectacle and security in Rio de Janeiro, Brazil, by juxtaposing scandals involving two football players, Vagner Love and Adriano, with policies attempting to secure Rio de Janeiro in advance of the 2014 World Cup and 2016 Olympics, especially the favela “pacification” policy. The scandals involving Vagner Love and Adriano centered on questions of race and social class, discipline, and urban space, leading to media-driven concern about security in contemporary Rio and, more broadly, about the shifting nature of structures of class, race and gender in post neoliberal Brazil. I argue that attentiveness to how concerns about class, race and place play themselves out in the arena of media commentary on soccer can help to draw attention to less visible anxieties about the favela “pacification” policy. More broadly, they illustrate anxieties about modes of governance and how these might impact Brazil’s performance on a global stage.

    Full Text Available Rotavirus is a major cause of infantile acute diarrhea, causing about 440,000 deaths per year, mainly in developing countries. The World Health Organization has been recommending the assessment of rotavirus burden and strain characterization as part of the strategies of immunization programs against this pathogen. In this context, a prospective study was made on a sample of 134 children with acute diarrhea and severe dehydration admitted to venous fluid therapy in two state hospitals in Rio de Janeiro, Brazil, from February to September 2004. Rotavirus where detected by polyacrylamide gel electrophoresis (PAGE and by an enzyme-linked immunoassay to rotavirus and adenovirus (EIARA in 48% of the children. Positive samples for group A rotavirus (n = 65 were analyzed by reverse transcription/heminested multiplex polymerase chain reaction to determine the frequency of G and [P] genotypes and, from these, 64 samples could be typed. The most frequent G genotype was G1 (58% followed by G9 (40%. One mixed infection (G1/G9 was detected. The only [P] genotype identified was [8]. In order to estimate the rotavirus infection frequency in children who acquired diarrhea as hospital infection in those hospitals, we studied 24 patients, detecting the pathogen in 41% of them. This data suggest that genotype G9 is an important genotype in Rio de Janeiro, with implications to the future strategies of vaccination against rotavirus, reinforcing the need of continuous monitoring of circulating strains of the pathogen, in a surveillance context.

    This study addressed the identification and monitoring of pollution sources of terrestrial origin in rivers (domestic sewage and industrial effluents) and critical fluvial segments in highly polluted environments under tidal influence (mixing marine and continental sources) from Guanabara Bay Basin, Rio de Janeiro, Brazil. The mass balance of contaminants was determined in conditions of continuous flow (low tide) during dry season (lower dilution capability). The results allowed the evaluation of the potential of contaminant mass generation by the different river segments and the estimation of their natural and anthropogenic components. The water quality of Iguaçú and Sarapuí Rivers were evaluated for metals and biochemical oxygen demand. The method gave an excellent response, including the possibility of sources identification and contaminated river segments ranking. The approach also offers fast execution and data interpretation, being highly efficient.

    A novel multivariate method based on principal component analysis of pre-processed sections of chromatograms is used to characterize the complex PAH pollution patterns in sediments from Guanabara Bay, Brazil. Five distinct sources of 3- to 6-ring PAHs could be revealed. The harbour is the most contaminated site in the bay, its plume stretches in a South West to North East direction and the chemical profile indicates mainly pyrogenic sources mixed with a fraction of high-molecular-weight petrogenic PAHs. Rio Sao Joao de Meriti is the second largest source of PAHs, and introduces mainly a fraction of low-molecular-weight petrogenic PAHs from the western region of Rio de Janeiro. The sites close to the ruptured pipeline at the Duque de Caxias Refinery show a distinctive pollution pattern indicating a heavy petroleum fraction. The method also led to the identification of new potential indicator ratios also involving coeluting peaks (e.g., triphenylene and chrysene). - A novel multivariate method is used to characterize the complex PAH pollution patterns in sediments from Guanabara Bay, Brazil.

    Full Text Available Surfing arrived in Brazil in 1938, giving rise to the first national surfers. By the 1970s, the sports had evolved into both a social and market structure, specifically in the states of Rio de Janeiro, São Paulo and Rio Grande do Sul, where surfboard producers, importers of materials and raw materials, promotion of championships and sporting events, as well as major brands and specialist stores began to open, starting a growing trend of new products and services. This paper analyzes the management operation of the surfing service sector in the State of Rio de Janeiro, and seeks to understand the complex relations between components, to explore those connections and make suggestions for future opportunities. The results show that Brazil is a strong consumer market of goods and services related to surfing due to the climate, young population, of which the majority lives close to the coast, features that are especially strong in Rio de Janeiro state. Among the factors that contribute to the development of surfing in Brazil is its insertion into the general media, in particular its projected image as a young and exciting activity, whose practice is related to psychological factors such as emotion, control of the external environment and overcoming challenges. The products and services that enable the consumer to overcome there physical and psychological challenges with the objective of achieving stronger control over these factors reveals growing possibilities for business and innovation.

  18. Dredging and disposal of fine sediments in the state of Rio de Janeiro, Brazil.

    Barbosa, M C; de Souza Soares de Almeida, M

    2001-07-30

    Dredging is employed quite frequently in the state of Rio de Janeiro, especially for the installation and upkeep of commercial ports and rehabilitation of the hydraulic section of silted bodies of water. Until recently, all dredged material with no economic use was destined for marine disposal or stored at the edge of the water body. Since the 1990s, however, a new approach has been adopted for dredging as a result of pressure from the environmental organisations, encouraging closer interaction in Rio de Janeiro between the local and state public authorities and the universities on issues relating to licensing of this kind of activity. The recent experiments of the Civil and Ocean Engineering Programs of COPPE-UFRJ (Federal University of Rio de Janeiro) described herein are included in this context. The state of Rio de Janeiro has three bays, several coastal lagoon systems and a number of small and medium sized rivers in or close to urban areas, with a gentle slope as they near the sea. This is, then, a region highly susceptible to silting processes of water bodies, and therefore, to maintenance and/or environmental rehabilitation. As discussed in the article, fine and almost always organic sediments prevail, which is a considerable obstacle to the end disposal and possibility of reuse.

    Full Text Available This study aimed to analyze time trends in complementary feeding practices among children under one year of age in the city of Rio de Janeiro, Brazil, from 1998 to 2008. Based on comparable questions on food consumption in five surveys conducted in representative randomized samples of children in 1998 (n = 3,762, 2000 (n = 3,670, 2003 (n = 4,305, 2006 (n = 3,686, and 2008 (n = 2,621, 16 complementary feeding indicators were constructed. The percentage frequency of all indicators was estimated for each year of the study. Linear trend analyses were also conducted by means of multivariate regression models. All indicators of early complementary feeding decreased from 1998 to 2008. In the 6-11.9 month age group, there was a significant downward trend in the proportion of children receiving food with adequate consistency for their age, consumption of iron-rich foods, and overall adequacy of the diet. A significant upward trend in fruit consumption was observed. There was a decrease in the early complementary feeding, and generally a worsening of complementary feeding practices in children aged 6-11.9 months in Rio de Janeiro during the period studied.

    Natural disasters are the result of extreme or intense natural phenomena that cause severe impacts on society. These impacts can be mitigated through preventive measures that can be aided by better knowledge of extreme phenomena and monitoring of forecasting and alert systems. The city of Petropolis (in a mountainous region of the state of Rio de Janeiro, Brazil) is prone to heavy rain events, often leading to River overflows, landslides, and loss of life. In that context, this work endeavored to characterize the thermodynamic and dynamic synoptic patterns that trigger heavy rainfall episodes and the corresponding flooding of Quitandinha River. More specifically, we reviewed events from the time period between January 2013 and December 2014 using reanalysis data. We expect that the overall description obtained of synoptic patterns should provide adequate qualitative aid to the decision-making processes involved in operational forecasting procedures. We noticed that flooding events were related to the presence of the South Atlantic Convergence Zone (SACZ), frontal systems (FS), and convective storms (CS). These systems showed a similar behavior on high-frequency wind components, notably with respect to northwest winds before precipitation and to a strong southwest wind component during rainfall events. Clustering analyses indicated that the main component for precipitation formation with regard to CS systems comes from daytime heating, with the dynamic component presenting greater efficiency for the FS configurations. The SACZ events were influenced by moisture availability along the vertical column of the atmosphere and also due to dynamic components of precipitation efficiency and daytime heating, the latter related to the continuous transport of moisture from the Amazon region and South Atlantic Ocean towards Rio de Janeiro state.

    The effects of environmental factors on the richness, diversity and abundance of ants were studied in the Restinga da Marambaia, south coast of Rio de Janeiro State, Brazil. The samples were taken using pitfall traps in August/2004 (winter) and March/2005 (summer) in three different vegetation types: (1) herbaceous ridge palmoid (homogeneous habitat); (2) shrub dune thicket and (3) ridge forest (heterogeneous habitats). At each habitat a range of environmental attributes was recorded: soil temperature and humidity, percentage of soil covering by litter and litter depth. Ninety-two ant species belonging to 36 genera and eight subfamilies were recorded. Density of ant species and abundance varied significantly between habitats and seasons; ant diversity varied only between habitats. Homogeneous habitat had lower ant species density, abundance and diversity than heterogeneous habitats. The two first variables were positively correlated with litter depth and both were higher in summer than in winter samples. There were more species of Ponerinae and Ectatomminae in heterogeneous than in the homogeneous habitat, whereas the Formicinae species were more abundant in the later.

    The urban suburbs of Brazilian cities have grown without an adequate sanitation infrastructure. Different social groups try to overcome these shortcomings seeking local sanitation alternatives at individual or community levels, contrasting with the universal model of sewage networks. This study was developed in the suburban neighborhood of Recreio dos Bandeirantes, Rio de Janeiro, Brazil, in order to analyze the installation process of the sewage system under a territorial approach. Data facilitated the construction of territorial schemes related to conflicts during the implementation of sewage networks in this neighborhood, where middle class groups and favela residents coexist with environmental preservation areas, beaches and commercial activities. This work revealed the need for contextualized sanitation information made available by the Brazilian Institute of Geography and Statistics (IBGE) and state sewage collection company, which conceal these conflicts or the representation of residents about their sanitation problems. Overlapping territorial managing functions should be considered as one of the factors responsible for the conflicts identified in the neighborhood. Further studies are suggested as methodological complementation and data update.

    This is a descriptive research, with qualitative approach, which aimed at analyze the interaction process between woman and her partner starting from the diagnosis of infection by the human papilomavirus (HPV). It was accomplished in 13 communities in the cities of Duque de Caxias and Nova Iguaçu, Rio de Janeiro state, Brazil, from October/2006 to September/2008. Twenty women, diagnosed with HPV infection related to oncogenic high risk, were interviewed. The Symbolic Interactionism and Grounded Theory perspectives guided data collection and analysis. The results revealed that the HPV diagnosis means serious challenges in the women's relationship with her partner mainly regarding to the adoption of preventive initiatives. It is concluded that these issues lead to the need of a humanized care in order to favor the women's empowerment.

    This paper presents the Conversion Project of Rio de Janeiro, Brazil, that converted all customers and the distribution network from Manufactured Gas (MG) to Natural Gas (NG), evaluating its logistic and benefits, highlighting those related to consumer safety. The Conversion Project was executed under the responsibility of CEG with the support of UERJ, specially on the definition and revision of the technical procedures as well as the quality assurance of the project execution. As main advantages followed by MG to NG network conversion, we can note: increasing of gas distribution network capacity and gas network operational condition improvements; elimination of production plant; revision and renovation of gas network; revision and repairing of building gas facilities; augmenting of NG usage; elimination of carbon monoxide as a supplied gas constituent. Conservation condition of most consumer internal gas facilities and ambient ventilation were so critical that conversion program resulted in no measurable accident prevention. The achieved safety level should be maintained through a periodically re-evaluation program of customer's gas facilities and appliances, with special focus on permanent ventilation required for NG safety usage.

    Full Text Available A evolução urbana do município do Rio de Janeiro durante o século XX, especialmente a partir da sua segunda metade, é fortemente marcada por crescentes privilégios concedidos ao crescimento da utilização dos meios de transporte de massa e, principalmente, individuais, feitos por veículos a motor de explosão. Uma das conseqüências desta política é a ascenção da mortalidade por acidentes de trânsito, verificada durante a década de 80, entre homens e mulheres de todas as idades. Neste trabalho demonstra-se também que, em 1990, apenas cerca de 1/3 das vítimas fatais nos acidentes de trânsito estavam "embarcadas" nos veículos. Portanto, a maioria dos óbitos por este tipo de acidente, cerca de 2/3, ocorreu por atropelamentos. Isto indica a necessidade de o poder público reverter a prioridade na prevenção das mortes por acidentes de trânsito em favor de medidas eficazes que protejam os pedestres.The evolution of the city of Rio de Janeiro during the 20th century, particularly since 1950, has been strongly characterized by increasing concession of privileges for the use of motor vehicles for both mass (and especially individual transportation. One of the main consequences of this policy was a rising mortality rate due to traffic accidents during the 1980s, among men and women of all ages. This paper demonstrates that in 1990 only about one-third of the fatal victims of traffic accidents were inside the vehicles involved. In Rio de Janeiro, the majority of deaths from this kind of accident (approximately two-thirds were pedestrians. Thus, policies aimed at reducing traffic-related mortality should give priority to the protection of pedestrians rather than drivers.

    The stomach contents of culicids from the Atlantic Forest in Rio de Janeiro state, Brazil, were analyzed using the precipitin technique to evaluate the feeding patterns of the species. Sampling was performed from February 2012 to December 2013, using CO2-baited Centers for Disease Control and Prevention traps to catch mosquitoes from 15 00 to 07 00 hours. The following antisera were used: bird, rodent, opossum, human, horse, capybara, lizard, and frog. Of the 325 adult bloodfed females caught and analyzed, 273 (84.0%) reacted in the precipitin test. The percentage of specimens with a positive reaction to a single antiserum included bird (39.2%), rodent (22.5%), opossum (13.2%), capybara (6.6%), horse (5.7%), frog (6.2%), human (4.0%), and lizard (2.6%). The specimens that reacted positively against more than one blood source (46) most frequently presented the following combinations: bird + rodent and bird + frog (17.4%), followed by bird + human (13.0%). The predominance of positive results for birds suggested that the avian-rich environment might have influenced the feeding behavior of the culicids. © The Authors 2015.

    There have been several recent changes in the taxonomy of Sporothrix schenckii as well as new observations regarding the clinical aspects of sporotrichosis. In this study, we determined the identification of the Sporothrix species associated with both classic and unusual clinical aspects of sporotrichosis observed in the endemic area of sporotrichosis in Rio de Janeiro, Brazil. To verify whether S. brasiliensis is associated with clinical manifestations of sporotrichosis, a cross-sectional study was performed in which Sporothrix isolates from 50 patients with different clinical manifestations were analyzed and their isolates were studied by phenotypic and genotypic methods. Data from these patients revealed a distinct clinical picture and therapeutic response in infections caused by Sporothrix brasiliensis (n = 45) compared to patients with S. schenckii sensu stricto (n = 5). S. brasiliensis was associated with disseminated cutaneous infection without underlying disease, hypersensitivity reactions, and mucosal infection, whereas patients with S. schenckii presented with less severe and more often localized disease, similar to the majority of previously described sporotrichosis cases. Interestingly, S. brasiliensis-infected patients overall required shorter durations of itraconazole (median 16 weeks) compared to the individuals with S. schenckii (median 24 weeks). These findings suggest that Sporothrix species are linked to different clinical manifestations of sporotrichosis and that S. brasiliensis is effectively treated with oral itraconazole.

    Full Text Available Foi realizada uma análise da incidência de exames realizados no Instituto Médico-Legal Afrânio Peixoto, Rio de Janeiro, Brasil, entre janeiro e julho de 2000. Foram selecionados 124 casos suspeitos de abuso sexual, envolvendo ambos os sexos em indivíduos com idade entre 0 e 17 anos. Os menores entre 0 e 14 anos representaram 81,45% da amostra, coincidindo com os índices observados em estudo anterior que abrangeu o primeiro trimestre do mesmo ano. O sexo masculino predominou nos casos suspeitos de atentado violento ao pudor - 20,97% do grupo, não havendo registro, em ambos os gêneros, entre 15 e 17 anos. O maior número de casos alegados de conjunção carnal (cópula vaginal foi observado no grupo de menores do sexo feminino entre 10 e 17 anos. Dos alegados agressores, 44,36% eram relacionados às vítimas; os desconhecidos corresponderam a 13,71% do grupo estudado. Em 30,65% dos casos não havia informação sobre o agressor. A maior parte dos registros de ocorrências policiais diz respeito às Zonas Norte e Oeste da cidade. O perfil sócio-econômico-cultural dos indivíduos examinados não foi contemplado no presente estudo.We present an incidence analysis of forensic medical examinations at the Afrânio Peixoto Institute of Forensic Medicine in Rio de Janeiro, Brazil, from January to July 2000. A sample of 124 cases of suspected sexual abuse was selected, both male and female, aged 0 to 17 years. Minors from 0 to 14 years of age represented 81.45% of the sample, coinciding with rates from a former study spanning the first quarter of 2000. Other than vaginal rape, young male subjects prevailed in cases of suspected anal, oral, or other forms of sexual violence and comprised 20.97% of the total sample, with no such cases, either male or female, in the 15-17-year group. Most cases of alleged vaginal sexual abuse were detected in the 10-17-year group. 44.36% of the alleged aggressors were related to the victims; non-related aggressors

    To assess the prevalence of elder abuse and to investigate potential sociodemographic, health behavior, and medical correlates. Cross-sectional data were collected in face-to-face assessments. São Paulo and Rio de Janeiro, Brazil. Individuals aged 60 to 75. Information on elder abuse was obtained using the Brazil-adapted, nine-item Hwalek-Sengstock Elder Abuse Screening Test. Sampling design-adjusted descriptive statistics and logistic regression were used in analyses. The overall prevalence of abuse was 14.4% (n = 46/259, 95% confidence interval (CI) = 9.82-20.61) in São Paulo and 13.3% (n = 27/197, 95% CI = 8.76-19.74) in Rio de Janeiro. Unadjusted analyses indicated that poor education, low physical activity, unemployment, heart disease, and psychiatric problems were associated with abuse, but in adjusted analyses, self-reported elder abuse was significantly associated only with psychiatric problems (São Paulo: OR = 4.48, 95% CI = 1.75-11.45; Rio de Janeiro: OR = 21.61, 95% CI = 6.39-73.14). Elder abuse is prevalent in São Paulo and Rio de Janeiro, but whether concomitants of abuse are cause, effect, or both is unclear because this was a cross-sectional study. These findings highlight the importance of the problem, as well as the need to develop measures to increase awareness, facilitate prevention, and fight against abuse of elderly adults. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Full Text Available Visceral Leishmaniasis has been showing remarkable epidemiological changes in recent decades, with marked expansion and an emergence of cases in urban areas of the North, Southeast and Midwest regions of Brazil. The Kala-azar cases reported here, despite being very characteristic, presented a great difficulty of diagnosis, because the disease is not endemic in Volta Redonda. The child underwent two hospitalizations in different hospitals, but got the correct diagnosis only after 11 months of symptom onset. In this report we discuss the main differential diagnoses and call attention to the suspected symptoms of visceral leishmaniasis in patients with prolonged fever, hepatosplenomegaly and pancytopenia, even in areas not traditionally endemic for the disease.

    Full Text Available The phytosociology of planted and natural mangrove forests were compared in the estuary of the Ostras River, Rio de Janeiro State, Brazil. Vegetation sampling was performed by the plot method, and the diameter at breast height (DBH and height of individuals > 1 m tall were recorded. The results indicated that the planted forest had lower average DBH and basal area and higher density of trunks in relation to natural forest. The distribution of individuals by height class and the distribution of stems per diameter class showed that the planted forest was younger. Laguncularia racemosa and Rhizophora mangle occurred in both forests, while Avicennia schaueriana was found only in the planted forest. Laguncularia racemosa showed greater dominance and relative density at all sites analyzed, probably because it is characteristic of sites with less marine influence and the fact that the estuary had been altered by human disturbance.

    Full Text Available Mycetoma is caused by the subcutaneous inoculation of filamentous fungi or aerobic filamentous bacteria that form grains in the tissue. The purpose of this study is to describe the epidemiologic, clinic, laboratory, and therapeutic characteristics of patients with mycetoma at the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil, between 1991 and 2014. Twenty-one cases of mycetoma were included in the study. There was a predominance of male patients (1.3:1 and the average patient age was 46 years. The majority of the cases were from the Southeast region of Brazil and the feet were the most affected anatomical region (80.95%. Eumycetoma prevailed over actinomycetoma (61.9% and 38.1% respectively. Eumycetoma patients had positive cultures in 8 of 13 cases, with isolation of Scedosporium apiospermum species complex (n = 3, Madurella mycetomatis (n = 2 and Acremonium spp. (n = 1. Two cases presented sterile mycelium and five were negative. Six of 8 actinomycetoma cases had cultures that were identified as Nocardia spp. (n = 3, Nocardia brasiliensis (n = 2, and Nocardia asteroides (n = 1. Imaging tests were performed on all but one patients, and bone destruction was identified in 9 cases (42.68%. All eumycetoma cases were treated with itraconazole monotherapy or combined with fluconazole, terbinafine, or amphotericin B. Actinomycetoma cases were treated with sulfamethoxazole plus trimethoprim or combined with cycles of amikacin sulphate. Surgical procedures were performed in 9 (69.2% eumycetoma and in 3 (37.5% actinomycetoma cases, with one amputation case in each group. Clinical cure occurred in 11 cases (7 for eumycetoma and 4 for actinomycetoma, and recurrence was documented in 4 of 21 cases. No deaths were recorded during the study. Despite of the scarcity of mycetoma in our institution the cases presented reflect the wide clinical spectrum and difficulties to take care of this neglected disease.

    Dengue dynamics in Rio de Janeiro, Brazil, as in many dengue-endemic regions of the world, is seasonal, with peaks during the wet-hot months. This temporal pattern is generally attributed to the dynamics of its mosquito vector Aedes aegypti (L.). The objectives of this study were to characterize the temporal pattern of Ae. aegypti population dynamics in three neighborhoods of Rio de Janeiro and its association with local meteorological variables; and to compare positivity and density indices obtained with ovitraps and MosquiTraps. The three neighborhoods are distinct in vegetation coverage, sanitation, water supply, and urbanization. Mosquito sampling was carried out weekly, from September 2006 to March 2008, a period during which large dengue epidemics occurred in the city. Our results show peaks of oviposition in early summer 2007 and late summer 2008, detected by both traps. The ovitrap provided a more sensitive index than MosquiTrap. The MosquiTrap detection threshold showed high variation among areas, corresponding to a mean egg density of approximately 25-52 eggs per ovitrap. Both temperature and rainfall were significantly related to Ae. aegypti indices at a short (1 wk) time lag. Our results suggest that mean weekly temperature above 22-24 degrees C is strongly associated with high Ae. aegypti abundance and consequently with an increased risk of dengue transmission. Understanding the effects of meteorological variables on Ae. aegypti population dynamics will help to target control measures at the times when vector populations are greatest, contributing to the development of climate-based control and surveillance measures for dengue fever in a hyperendemic area.

    2015-01-01

    The objective of this article is to analyze the background of the historiography of psychoanalysis in Rio de Janeiro. Three different phases and approaches are analyzed, based on the viewpoints of different groups of authors. The first group features authors who displayed an early interest in the subject, in the 1920's-1930's. The second refers to psychiatrists/psychoanalysts who worked with mental health institutes and societies between the 1940's and 1970's, while the third perspective comes from the academic/university environment, from the end of the 70's to the present. This distinction was made not only to better define the timeframe of the arrival and dissemination of psychoanalysis in Rio de Janeiro, but also to provide a better understanding of the relation between the specific professional and intellectual interests of each group and the respective historical context.

    Full Text Available OBJETIVO: Existe uma expressiva subnotificação de casos de Aids no Município do Rio de Janeiro, RJ. Nesse sentido, foi realizado estudo com o objetivo de analisar os fatores associados a esse evento. MÉTODOS: Com base em dados do Sistema de Informações Hospitalares do Sistema Único de Saúde, referentes ao ano de 1996 e ao Município do Rio de Janeiro, e do Sistema de Informações sobre Agravos de Notificação, atualizado até setembro de 1997, selecionou-se uma amostra aleatória de prontuários, pela qual os pacientes foram classificados em notificados, não notificados e sem evidência para notificação. Foi utilizado um modelo multinomial para a análise das chances de ocorrência de subnotificação versus notificação e não-notificação sem evidência de diagnóstico de Aids versus notificação. RESULTADOS: Não foram encontradas associações estatisticamente significativas entre as variáveis "idade", "estado civil", "escolaridade", "ocupação" e "gravidade da doença" e subnotificação de casos de Aids. A variável "sexo feminino" apresentou forte associação com as internações por procedimento Aids sem evidências para `fechar caso' dessa doença. Foi encontrada associação bastante expressiva entre ter sido internado no mesmo hospital mais de uma vez e estar notificado. A presença de um setor de vigilância epidemiológica no hospital esteve inversamente associada à subnotificação de casos de Aids. CONCLUSÕES: Os resultados mostraram que a associação significativa entre variáveis organizacionais e estruturais e subnotificação de casos de AIDS apontam para a necessidade de normatização de processos e fluxos, a fim de melhorar a qualidade do sistema de informações em saúde.OBJECTIVE: The underreporting of AIDS cases in the municipality of Rio de Janeiro, Brazil, is significant.

    To analyze sociocultural differences and perceptions of gynecological consultations for high school girls. A transversal study with 418 high school girls from three schools of different profiles in the city of Rio de Janeiro, Southeastern Brazil in 2010. A structured questionnaire encompassing socio-demographic characteristics, sexual behavior and evaluation of gynecological consultations was completed. Yates' Chi-square test and the Student's t-test were utilized adopting a value of p students of private and federal public schools presented similar profiles but both were different from the state school girls. The latter had lower socioeconomic status, and their parents had lower levels of education, the predominance of afro-descendants was observed, as were a larger number of sexual partners, pregnancy and cases of sexual violence. The average age of menarche and sexarche among the students were similar, but the first gynecological consultation was significantly later among the state school students. The majority showed some knowledge of contraception and STDs, although only a minority received guidance from the consultations. Students expressed the desire that the professionals dedicate more time, patience and availability to them during consultations. The provision of gynecological services for teenagers is not satisfactory, according to the teenagers' evaluations. Users of the private health system have gynecological consultations earlier than those who only have access to the public system. It is necessary to create mechanisms that facilitate access and adhesion to a routine of gynecological prevention for this age group.

    Vector-borne diseases transmitted by insect vectors such as mosquitoes occur in over 100 countries and affect almost half of the world's population. Dengue is currently the most prevalent arboviral disease but chikungunya, Zika and yellow fever show increasing prevalence and severity. Vector control, mainly by the use of insecticides, play a key role in disease prevention but the use of the same chemicals for more than 40 years, together with the dissemination of mosquitoes by trade and environmental changes, resulted in the global spread of insecticide resistance. In this context, innovative tools and strategies for vector control, including the management of resistance, are urgently needed. This report summarizes the main outputs of the first international workshop on Insecticide resistance in vectors of arboviruses held in Rio de Janeiro, Brazil, 5-8 December 2016. The primary aims of this workshop were to identify strategies for the development and implementation of standardized insecticide resistance management, also to allow comparisons across nations and across time, and to define research priorities for control of vectors of arboviruses. The workshop brought together 163 participants from 28 nationalities and was accessible, live, through the web (> 70,000 web-accesses over 3 days).

    Full Text Available ABSTRACT Marine sponges has been a large reservoir of microbial diversity, with the presence of many species specific populations as well as producing biologically active compounds, which has attracted great biotechnological interest. In order to verify the influence of the environment in the composition of the bacterial community present in marine sponges and biotechnological potential of bacteria isolated from these organisms, three species of sponges and the waters surrounding them were collected in different beaches of Rio de Janeiro, Brazil. The profile of the bacterial community present in sponges and water was obtained by PCR-DGGE technique and the biotechnological potential of the strains isolated by producing amylase, cellulase, protease and biosurfactants. The results showed that despite the influence of the environment in the composition of the microbial community, studied marine sponges shown to have specific bacterial populations, with some, showing potential in the production of substances of biotechnological applications.

    This study aims to assess pesticide exposure risk perception among farmers from three rural areas of Nova Friburgo, Rio de Janeiro State, Brazil. Data were collected through semi-structured interviews with 66 adults and participatory workshops with 27 teenagers and analyzed through content analysis techniques. Systematized results were discussed at local meetings, and two risk communication initiatives were devised. Study results demonstrated the use of defensive strategies by men and a diminished risk perception among women. Teenagers relied on parents to develop their own work practices. These findings supported the importance of cultural and social determinants of farmers' understandings of risk and of the relevance of different pesticide exposure pathways. Risk perceptions and work practices are strongly influenced by local cultural patterns and, therefore, must be taken into account when developing effective intervention strategies, including risk communication initiatives.

    Full Text Available There is considerable data to support a central role for human papillomavirus (HPV in the etiology of cervical cancer. More than a 100 HPV types have been described, and 40 have been isolated from benign and malignant genital lesions. Consequently, there is strong motivation to evaluate HPV testing for cervical cancer screening. Few studies concerning the natural history of HPV infection have been conducted in the state of Rio de Janeiro. We determined the prevalence of HPV types in female genital lesions by using Hybrid Capture Assay (HCA and we retrospectively analyzed the course of HPV infection. Our sample included 788 women attended at Laboratórios Sérgio Franco. The average age of the participants was 29.6 years. HPV prevalence and cytological diagnosis were determined. The overall prevalence of HPV DNA in the study group was 50.1% (395/788, ranging from 25% (NORMAL to 100% in high-grade intraepithelial lesions (HSIL. High risk HPV was found in 12% inflammatory, 58.3% HPV, 63.2% LSIL and 100% HSIL. A retrospective analysis of 78 patients showed that 22 presented persistent lesions, 2 had progressive lesions, 4 had regressive lesions, 13 showed latent infections, 18 were transiently infected and 19 were submitted to curative treatment. No cases of cancer were registered in this population, which can afford private medical care and regular follow-up exams. We suggest that HCA be used in specific cases involving persistent and recurrent lesions.

    Salmonella is a major foodborne pathogen that constantly threatens food safety in developed countries and underdeveloped countries such as Brazil, where it is responsible for 38% of notified cases of foodborne illness. Swine are one of the main meat-producing species that may asymptomatically carry Salmonella, periodically shedding the bacteria through feces. The state of Rio de Janeiro is not a major producer of swine meat, but small slaughterhouses are operational and produce meat for consumption within the state, although few studies have been conducted in the region. In this context, this study was designed to evaluate Salmonella contamination in carcasses, lymph nodes, feces, utensils, and the environment of three small slaughterhouses in the state of Rio de Janeiro. A total of 344 samples from carcasses, utensils, equipment, water, and the environment were collected from these slaughterhouses in the northwestern region of Rio de Janeiro. Salmonella was isolated from 36 (10.5%) samples: 10 of 48 carcasses, 19 of 96 lymph nodes, 4 of 48 fecal samples, 2 of 6 water samples, and 1 of 6 bleeding knives; 55 isolates were recovered. Serotyping revealed the predominance of Salmonella Typhimurium (20 isolates) followed by Salmonella Abony (10 isolates), Salmonella Give (7 isolates), Salmonella Heidelberg (4 isolates), and Salmonella Infantis (1 isolate). Ten isolates were only partially typeable, with only their O antigen identified, and three isolates had rough, nontypeable colonies. Despite the overall low prevalence of Salmonella in this study, all three slaughterhouses had poor hygienic and sanitary conditions, providing easy routes for carcass and, consequently, meat contamination. Thus, it is imperative to enforce sanitary inspections in these establishments and to apply good manufacture practices to assure the safety of the produced pork.

    Full Text Available Research on fishing activity at Atafona village, in Northern Rio de Janeiro, Brazil (21°35'S, was carried out between 1987-96 for the purpose of relating it to the accidental capture of small cetaceans and of estimating the relationship between fishing activity and the diet of small cetaceans. Data on fishing operations were obtained at the cold storage plants management, from interviews with fishermen and personal observations. The most representative fishing resources were Xyphopenaeus kroyeri, Micropogonias furnieri, Carcharhinus plumbeus, C. acronotus,and Rhizoprionodon porosus. Gillnets are responsible for the accidental capture of small cetaceans in the region, mainly Pontoporia blainvillei and Sotalia fluviatilis (marine form. Four types of gillnets that are used on the region ("minjuada", "sarda", "caçoá" and "pescadinha" were dangerous to these species because they are placed in their preferred habitat. There is no competition between fishermen and small cetaceans due to the selection in the capture of commercialized fishesInvestigação sobre a atividade pesqueira na localidade de Atafona, Norte do Rio de Janeiro, Brasil (21º25`S, foi conduzida entre 1987-96 com o objetivo de relacioná-la com a captura acidental e a dieta dos pequenos cetáceos.

    In recent decades the Brazilian population has undergone intense changes in its nutritional conditions, especially with an increase in obesity. According to the National Survey on Health and Nutrition in 1989, 32.0% of adults were overweight. However, distribution of the problem is not homogeneous. The highest prevalence occurs among poor women in the Southeast. Understanding this apparent paradox requires the search for approaches capable of overcoming simplistic interpretations about eating practices. Thus, the objective of this study was to understand obesity combined with poverty, focusing beyond economic determinants on constraints of a cultural and symbolic nature. From this perspective, the study analyzed the daily lives of poor women who used a Municipal Health Center and resided in the Rocinha slum in Rio de Janeiro. The results showed the complexity of the relationship between obesity and poverty. Cultural and material life aspects as well as different concepts of eating and the body proved to be fundamental elements for the analysis of the multiple facets of obesity in Brazil.

    This study focuses on metals analysis in kidney and liver tissues of Egretta thula which were collected prostrate or newly dead in Coroa Grande mangrove, Sepetiba Bay, Rio de Janeiro, Brazil, between March 2005 and October 2008. Kidney and liver were collected and analysed to evaluate heavy metal pollution. High values and widest range were detected for all metals in liver and kidney tissues. Geometric mean differences from metals concentrations for Zn, Cd, Ni, Pb, Cu, and Cr, respectively, were found in both organs. Results from linear regression analysis were non-significant in kidney (r = -0.79975, P = 0.10428), and in liver (r = -0.53193, P = 0.35618). With ANOVA analysis for metal accumulation differences (kidney*liver), at the 0.05 level, the results were significantly different (F = 33.17676, P = 0.00000; F = 12.47880, P = 0.00000). These results indicate that Sepetiba Bay shows worrying levels of metals in this study with E. thula, showing potential power of widespread biological and mutagenic adverse effects in trophic levels, and therefore, signalling risk to human health.

    This article compares food intake by women 35 years or older in two population-based cross-sectional studies in Rio de Janeiro, Brazil, in 1995-1996 (n = 1,014) and 2004-2005 (n = 1,001). Food intake was assessed with a food-frequency questionnaire, and nutritional status was defined according to body mass index (BMI = weight/height(2)). Prevalence of obesity (BMI 30 kg/m(2)) increased in the ten-year period (16.6% to 24%). Many high energy density (kcal/g) foods showed a statistically significant increase in the period, such as crackers, candies, bacon, sausage, and hamburger. Some high energy density items were reported less frequently: butter, mayonnaise, potato chips, and sugar. The intake of fruits, milk, beans, roots and potatoes, and meat decreased in the 10-year period. Women with more education showed a larger reduction in fruit and meat intake and a smaller reduction in fish, dairy product, and root and potato intake. Changes in prevalence of obesity were associated with numerous changes in food intake, depending on the level of schooling.

Realizou-se um estudo qualitativo sócio-antropológico com 14 famílias do Rio de Janeiro, Brasil, cujos filhos permaneciam solteiros e residindo com os pais, após o nascimento da criança. Foram realizadas 25 entrevistas em profundidade com 6 rapazes e 7 moças entre 18 e 24 anos e seus pais (11 mães e 1 pai, para avaliação retrospectiva da gravidez e de seus impactos na trajetória juvenil e familiar. Três aspectos são analisados: as dificuldades de internalização da norma contraceptiva; a descoberta tardia da gravidez e a tomada de decisão ­ aborto ou reprodução ­ pelos jovens e seus pais. O estudo permitiu configurar a gravidez na adolescência como um evento contingente ao processo de construção da autonomia pessoal em curso nessa fase da vida, no qual a sexualidade tem grande relevância. Conclui-se que o fenômeno precisa ser compreendido em um contexto histórico e cultural específico, distinto de sua ocorrência décadas atrás, pois está marcado pelas regras que organizam o processo de individualização juvenil na contemporaneidade.The subject of this paper is teenage pregnancy among middle-class youth, a topic not sufficiently studied in Brazil. The paper is based on a qualitative, socio-anthropological study of 14 middle-class families in Rio de Janeiro, Brazil, whose children have remained single, living with their parents after the child's birth. A total of 25 in-depth interviews were conducted with 6 young men and 7 young women, ages 18 to 24, and their parents (11 mothers, one father, to examine the event in retrospect and its impact on these young people and their families. Three aspects are analyzed: difficulties young people face in internalizing contraception as a norm; late discovery of pregnancy; and how the decision to either have an abortion or give birth is made by young people and their parents

    Instituto de Ginecologia (Institute of Gynecology), in Rio de Janeiro, headed by Dr. Arnaldo de Moraes, was the first institution in Brazil to introduce and divulge medical techniques for the control of cervical cancer in the mid-1900s. It became a benchmark for actions geared towards the disease at the time, organizing a specific diagnostic procedure that set Brazilian medicine apart in the field, in which it remained a leader until the 1970s. The aim of this text is to discuss the organization and running of the institution from two perspectives: its role in enhancing the position of gynecology as a medical specialty, and its role in spreading a standard practice for the control of cervical cancer.

    Full Text Available OBJECTIVE: To determine the frequency of and the factors related to delayed diagnosis of sarcoidosis in Brazil. METHODS: We evaluated patients with a biopsy-proven diagnosis of sarcoidosis, using a questionnaire that addressed the following: time since symptom onset and since the first medical visit; and the number and specialty of the physicians visited. We divided the patients by the timeliness of the diagnosis-timely (< 6 months and delayed (≥ 6 months-comparing the two groups in terms of systemic and pulmonary symptoms; extrathoracic involvement; spirometric data; radiological staging; level of education; income; and tuberculosis (diagnosis and treatment. RESULTS: We evaluated 100 patients. The median number of physicians consulted was 3 (range, 1-14. In 11 cases, sarcoidosis was diagnosed at the first visit. In 54, the first physician seen was a general practitioner. The diagnosis of sarcoidosis was timely in 41 patients and delayed in 59. The groups did not differ in terms of gender; race; type of health insurance; level of education; income; respiratory/systemic symptoms; extrathoracic involvement; and radiological staging. In the delayed diagnosis group, FVC was lower (80.3 ± 20.4% vs. 90.5 ± 17.1%; p = 0.010, as was FEV1 (77.3 ± 19.9% vs. 86.4 ± 19.5%; p = 0.024, misdiagnosis with and treatment for tuberculosis (≥ 3 months also being more common (24% vs. 7%, p = 0.032, and 20% vs. 0%; p = 0.002, respectively. CONCLUSIONS: The diagnosis of sarcoidosis is often delayed, even when the imaging is suggestive of sarcoidosis. Delayed diagnosis is associated with impaired lung function at the time of diagnosis. Many sarcoidosis patients are misdiagnosed with and treated for tuberculosis.

    Dengue, a reemerging disease, is one of the most important viral diseases transmitted by mosquitoes. Climate is considered an important factor in the temporal and spatial distribution of vector-transmitted diseases. This study examined the effect of seasonal factors and the relationship between climatic variables and dengue risk in the city of Rio de Janeiro, Brazil, from 2001 to 2009. Generalized linear models were used, with Poisson and negative binomial distributions. The best fitted model was the one with "minimum temperature" and "precipitation", both lagged by one month, controlled for "year". In that model, a 1°C increase in a month's minimum temperature led to a 45% increase in dengue cases in the following month, while a 10-millimeter rise in precipitation led to a 6% increase in dengue cases in the following month. Dengue transmission involves many factors: although still not fully understood, climate is a critical factor, since it facilitates analysis of the risk of epidemics.

    Full Text Available This work is based on the study of the core T1 collected in the Guaratiba Mangrove, located on the northeastern margin of Sepetiba Bay. Few studies dealing with the application of benthic foraminifera to study sea level changes during the Holocene have been conducted in Sepetiba Bay, State of Rio de Janeiro, Brazil. In order to fill this gap, the core T1 was studied using textural, geochemical (carbonate, total organic carbon, total sulfur and stable isotopes evaluated in Ammonia tepida and microfaunal (benthic foraminifera data, unveiling paleoecological relationships of these organisms and the evolutionary scenario of Guaratiba Mangrove. Radiocarbon results indicate an estimated age of about 2400 yrs cal BP for the core base. Textural, geochemical and benthic foraminifera data suggest that the study area changed significantly during the last 2400 yrs cal BP. It experienced coastal waves action and shoreface processes in the period between ≈2.400-1.400 yrs cal BP; then, this phase gave place to a shallow marine environment similar to that found currently in internal and protected areas of Sepetiba Bay, between ≈1.400-350 yrs cal BP. Thenceforth, the study area evolved to the present mangrove environment. Factors related to climatic oscillations and the formation, evolution and events of rupture of Marambaia sand ridge influenced the late Holocene evolution of the northeast intertidal area of Sepetiba Bay.

    Full Text Available Dengue epidemics have occurred in the city of Rio de Janeiro (Brazil since 1986. In the year 2015, Zika and chikungunya viruses were introduced in the city, causing sequential and simultaneous epidemics. Poor socioeconomic conditions have been suggested as contributing factors of arboviral infection.To describe the spatial distribution of human cases of symptomatic arboviral infections and to identify risk factors for infection in a poor community of Rio de Janeiro in the years 2015 and 2016.We built thematic maps of incidence rates for 78 micro-areas in the Manguinhos neighborhood. The micro-areas congregate about 600 inhabitants. Simple and multiple multilevel logistic regression models were used to evaluate the association between the incidence of arboviral diseases and socio-demographic factors at both the individual and micro-area levels.From 2015 to 2016, 370 human cases of arbovirus infection were reported in the Manguinhos community: 123 in 2015 and 247 in 2016. There was a significant difference in the risk of arbovirus diseases among different micro-areas, but this was not explained by water and sanitation indicators. The cumulative incidence rate was 849/100,000 in two years. The incidence was greater in those individuals with familiar vulnerability (1,156/100,000 vs. 794/100,000. The multilevel adjusted model showed that the odds of acquiring an arbovirus infection was 55% greater in those with familiar vulnerability.Arbovirus infections cause a high burden of disease in Brazilian urban centers. Our results suggest that even in poor neighborhoods, there is a high spatial variability in the risk of acquiring an arbovirus infection. The conditions that favor vector proliferation and infection by arboviruses are complex and involve both individual and environmental characteristics that vary from place to place. To reduce the burden of arboviral diseases, continued public health policies and basic services should be provided to the

    2016-09-01

    Full Text Available The Americas have suffered a dramatic epidemic of Zika since May in 2015, when Zika virus (ZIKV was first detected in Brazil. Mosquitoes belonging to subgenus Stegomyia of Aedes, particularly Aedes aegypti, are considered the primary vectors of ZIKV. However, the rapid spread of the virus across the continent raised several concerns about the transmission dynamics, especially about potential mosquito vectors. The purpose of this work was to assess the vector competence of the house mosquito Culex quinquefasciatus from an epidemic Zika area, Rio de Janeiro, Brazil, for local circulating ZIKV isolates.Culex quinquefasciatus and Ae. aegypti (positive control of ZIKV infection from Rio de Janeiro were orally exposed to two ZIKV strains isolated from human cases from Rio de Janeiro (Rio-U1 and Rio-S1. Fully engorged mosquitoes were held in incubators at 26 ± 1°C, 12 h:12 h light:dark cycle and 70 ± 10% humidity. For each combination mosquito population-ZIKV strain, 30 specimens were examined for infection, dissemination and transmission rates, at 7, 14 and 21 days after virus exposure by analyzing body (thorax plus abdomen, head and saliva respectively. Infection rates were minimal to completely absent in all Cx. quinquefasciatus-virus combinations and were significantly high for Ae. aegypti. Moreover, dissemination and transmission were not detected in any Cx. quinquefasciatus mosquitoes whatever the incubation period and the ZIKV isolate. In contrast, Ae. aegypti ensured high viral dissemination and moderate to very high transmission.The southern house mosquito Cx. quinquefasciatus from Rio de Janeiro was not competent to transmit local strains of ZIKV. Thus, there is no experimental evidence that Cx. quinquefasciatus likely plays a role in the ZIKV transmission. Consequently, at least in Rio, mosquito control to reduce ZIKV transmission should remain focused on Ae. aegypti.

    This study aimed at estimating the prevalence of postpartum depression (PPD) according to postpartum periods and sub-groups in public primary health care settings in Rio de Janeiro, Brazil. A cross-sectional survey was carried out in five primary health care units and included 811 participants randomly selected among mothers of children up to five postpartum months. Women were classified as depressed and given scores on Edinburgh Postnatal Depression Scale (EPDS) above 11. The overall estimate of PPD was 24.3% (95% CI, 21.4-27.4). However, estimates were not homogeneous during the first 5 months postpartum (p value = 0.002). There was a peak of depressive symptoms around 3 months postpartum, when 128 women (37.5%, 95% CI, 29.1-46.5) disclosed scores above 11 on EPDS. Regarding the magnitude of PPD according to some maternal and partners' characteristics, it was consistently higher among women with low schooling, without a steady partner, and whose partners misused alcohol or used illicit drugs. The prevalence of PPD among women attending primary health care units in Rio de Janeiro seems to be higher than general estimates of 10-15%, especially among mothers with low schooling and that receive little (if any) support from partners. Also, the "burden" of PPD may be even higher around 3 months postpartum. These results are particularly relevant for public health policies. Evaluation of maternal mental health should be extended at least until 3 to 4 months postpartum, and mothers presenting a high-risk profile deserve special attention.

A week prior (May 5, the same specimen (identified by a parallel scar pattern had been observed at Costão Beach (24º19’S; 47º00’W, Peruíbe, São Paulo State. Two days later, the animal reappeared at Barra do Sahy Beach (23º47’S; 45º33’W, São Sebastião, São Paulo. Subsequently, the seal’s further northerly displacement to Cação River made a total distance covered of 229km. The occurrence of two cold fronts and the prevalence of southern currents in the first fortnight of May may have favored the displacement of this Ocorrência de Lobodon carcinophagus no Rio de Janeiro animal to areas of low latitude in southeastern Brazil. On June 16, 2003, a male of approximately 200cm in length was seen in Tombo Beach (24º00’S ; 46º18’W, Guarujá (São Paulo. It was the second appearance of L. carcinophagus in São Paulo in 41 days. This note confirms the occasional occurrence of this species along the Brazilian coast, and provides insights into the dispersion of the species in the southwestern Atlantic.

    Full Text Available The introduction of highly active antiretroviral therapy during the 1990s was crucial to the decline in the rates of morbidity and death related to the acquired immunodeficiency syndrome (AIDS and turned human immunodeficiency virus (HIV infection into a chronic condition. Consequently, the HIV/AIDS population is becoming older. The aim of this study was to describe the immunological, clinical and comorbidity profile of an urban cohort of patients with HIV/AIDS followed up at Instituto de Pesquisa Clinica Evandro Chagas, Oswaldo Cruz Foundation in Rio de Janeiro, Brazil. Retrospective data from 2307 patients during January 1st, 2008 and December 31st, 2008 were collected. For continuous variables, Cuzick's non-parametric test was used. For categorical variables, the Cochran-Armitage non-parametric test for tendency was used. For all tests, the threshold for statistical significance was set at 5%. In 2008, 1023 (44.3%, 823 (35.7%, 352 (15.3% and 109 (4.7% were aged 18-39, 40-49, 50-59 and >60 years-old, respectively. Older and elderly patients (>40 years were more likely to have viral suppression than younger patients (18-39 years (p 0.001. No significant difference in the latest CD4+ T lymphocyte count in the different age strata was observed, although elderly patients (> 50 years had lower CD4+ T lymphocyte nadir (p 0.02. The number of comorbidities increased with age and the same pattern was observed for the majority of the comorbidities, including diabetes mellitus, dyslipidemia, hypertension, cardiovascular diseases, erectile dysfunction, HCV, renal dysfunction and also for non-AIDSrelated cancers (p 0.001. With the survival increase associated to successful antiretroviral therapy and with the increasing new infections among elderly group, the burden associated to the diagnosis and treatment of the non-AIDS related HIV comorbidities will grow. Longitudinal studies on the impact of aging on the HIV/AIDS population are still necessary

    Full Text Available Imposex, an endocrine disruption phenomenon, is a biomarker of tributyltin (TBT exposure in marine gastropod populations. The occurrence and intensity of the syndrome in populations of the neogastropod Stramonita haemastoma were ascertained at nine sampling stations in October 2008 at Arraial do Cabo, a very important tourist resort in Rio de Janeiro state (Brazil and part of the Marine Extractive Reserve of Arraial do Cabo. The results obtained made it possible to evaluate the changes which had occurred since the last biomonitoring campaign, undertaken in 2001, at these same stations. Despite the ban on the use of TBT imposed by the Brazilian Navy in 2003, the controls on the use of this agent in Brazil resulting from the establishment of NORMAM 23 by the Navy in 2007 and the complete ban of organotin compounds in antifouling paint formulae by the IMO on a global scale in 2008, imposex was still detected. Instead of the expected reduction, an increase was observed in the areas affected by imposex. Furthermore, populations in the areas seriously affected by imposex in 2001 were absent in the 2008 sampling campaign. These results suggest an increase in TBT pollution in the study area, indicating the inefficacy of legislative measures.O imposex, um fenômeno de desregulação endócrina, é um biomarcador da exposição ao tributilestanho (TBT em populações de gastrópodes marinhos. A ocorrência e intensidade dessa síndrome nas populações do neogastrópode Stramonita haemastoma foram verificadas em nove estações amostrais em outubro de 2008 em Arraial do Cabo, uma área de grande importância turística no Rio de Janeiro (Brasil e integrante da Reserva Extrativista Marinha de Arraial do Cabo. Com os resultados obtidos foi possível avaliar as alterações ocorridas desde o último biomonitoramento realizado em 2001, nessas mesmas estações.

    Full Text Available Within the scope of the MAR-14 Project, part of the Brazil-Germany Bilateral Agreement in Marine Sciences, an oceanographic survey aboard the R/V Victor Hensen was carried out in Brazilian coastal waters between Santos (23º56'S and Rio de Janeiro (22º54'S, from January 15 to January 22,1991. In this article we report results of preliminary analyses of the hydrographic data collected with CTD, STD, Nansen bottles and XBT's. These preliminary results show intense stratification in the first 200 m depth, and the penetration of the Brazil Current deep into the continental shelf region. Two eddy-like features were detected. The first one, anticyclonic, was located in the northern part of the domain and confined to the uppermost 200 m. The second, a cyclonic vortex, was found a little to the southwest below 200 m and extending downwards to about 800 m depth. Water mass analyses based on T-S diagrams suggest that the interface between the South Atlantic Central Water (SACW and the Antarctic Intermediate Water (AIW is located at about 500 m depth. One important aspect of this study is that this was the first time a high resolution survey with a CTD probe was realized along the eastern Brasilian Coast, south of Cabo Frio.Como parte do projeto MAR-14, componente do Acordo Bilateral Brasil-Alemanha em Ciências Marinhas, uma campanha oceanógrafica a bordo do R/V Victor Hensen foi realizada em águas costeiras do Brasil entre Santos (23º56'S, de 15 a 22 de janeiro de 991.

    Brazil is signatory of international protocols for receiving the visit of nuclear ships and submarines. Such naval units, during their stays in Brazilian ports, inform that there is no release of radioactive material to the environment. However, there is always the possibility of an accident, leading to environmental release of radioactive material. This work had the objective of assessing the potential radiological environmental impact due to the eventual occurrence of an accident during the permanence of ships and submarines of nuclear propulsion in the port of the city of Rio de Janeiro, in Guanabara Bay. The accident scenarios considered include releases to the marine environment and to the atmosphere. Previous results indicated that, in normal operation conditions, no significant radiological impact is foreseen due to the visits of nuclear submarines to the city, even if small routine radionuclide releases occur. The analysis of the accidental releases, however, indicates that the anchorage points should be located at a minimum distance of 2,5 km of inhabited areas in the contour the Bay. (author)

    To describe the difficulties and peculiarities encountered by health professionals during the treatment and investigation of contacts of tuberculosis (TB) patients in disadvantaged communities. A qualitative study carried out at health care facilities in Health Programming Area 1.0, located in the city of Rio de Janeiro, Brazil, which has a TB incidence rate of 240/100,000 inhabitants. From among the professionals responsible for visiting and treating TB cases and their contacts, two home visit agents and one clinical nurse were selected to be interviewed for the study. Data were transcribed and structured in the form of quotations, emphasizing the predominant ideas. The central ideas focus on the issue of violence, one significant facet of which is the set of rules imposed by narcotraffickers, and on the barriers to the movement of patients/health professionals for TB treatment, as well as on public safety (police). This study provides public health officials, as well as institutions that graduate health professionals, data for reflection and analysis of the difficulties that urban violence creates for the control of TB in a disadvantaged community.

    The aim of this study was to assess the sociodemographic risk factors for urinary tract infection and the inadequacy of antenatal care, according to the Kotelchuck index, in pregnant women in the city of Rio de Janeiro. A cross-sectional study was conducted with 1,091 pregnant women, 501 with urinary tract infection, in the public health antenatal care units in Rio de Janeiro, Brazil, in 2007-2008. Demographic and socioeconomic data, obstetric history and adequacy of antenatal care were collected by interviews and antenatal care card. Inadequacy management of urinary tract infection was evaluated by professional performance, health services and women dimensions. Chi-square and multivariate logistic regression were used to compare groups and to identify associated factors with management of urinary tract infection. Pregnant teenagers, anemic and diabetic pregnant women and quality of prenatal partially adequate or inadequate were those with higher odds of urinary tract infection. In the overall assessment, 72% had inadequate management of urinary tract infection. Inadequate management of urinary tract infection was associated with brown skin color compared to white skin color. In the assessment of health professional performance, inadequacy management of urinary tract infection was more common in pregnant women with low weight and overweight and obesity. According to pregnant women evaluation, primiparous women have lower odds of inadequacy management of urinary tract infection compared to those with one or more children.

    Full Text Available Counseling for human immunodeficiency virus infected travelers is becoming increasingly specialized. Previous studies have reported the experience of HIV-infected travelers from temperate-climate countries but little is known about HIV-infected travelers from tropical countries. A retrospective study was conducted on HIV-infected travelers presenting at a travel health clinic in Rio de Janeiro. Eleven journeys by ten people were recorded. Brazil (Amazon region and Northeast was the destination for six journeys. Other destinations were Peru, Angola, Europe and Asia. Nine attendees were undergoing antiretroviral therapy. Few HIV-infected people from Rio de Janeiro consulted a travel medicine specialist before traveling. Since they travel to destinations in Brazil and abroad where there are endemic diseases not encountered in Rio de Janeiro, careful pre-travel planning needs to be undertaken. Strategies for increasing the frequency of pre-travel consultations need to be developed, such as closer collaboration between HIV clinics and travel health clinics.O aconselhamento para os viajantes infectados pelo vírus da imunodeficiência humana está se especializando cada vez mais. Estudos prévios relatam a experiência dos viajantes infectados pelo vírus da imunodeficiência humana dos países de clima temperado, mas pouco se sabe sobre os viajantes infectados pelo vírus da imunodeficiência humana dos países tropicais. Foi realizado um estudo retrospectivo dos viajantes infectados pelo vírus da imunodeficiência humana que consultaram um serviço de medicina de viagem no Rio de Janeiro. Dez viajantes realizaram onze viagens. O Brasil (Amazônia e Nordeste foi o destino de seis viagens. Outros destinos foram Peru, Angola, Europa e Ásia.

    The south coast of Rio de Janeiro State, in Brazil, is endemic for cutaneous and visceral leishmaniases and is frequently visited by tourists from different parts of the world. Since the complex epidemiology of leishmaniases demands local studies, the goal of this study was to investigate the phlebotomine sand fly fauna and leishmaniases transmission in Ilha Grande, an ecotourism area of Angra dos Reis municipality. Sand fly fauna was sampled in three monitoring stations using HP light traps in domiciles, peridomiciles and forests. Species abundance was evaluated by the Index of Species Abundance. A Leishmania natural infection survey was done using multiplex PCR and dot blot hybridization. During 15 consecutive months of sand fly monitoring, 1093 specimens from 16 species were captured. The potential leishmaniases vectors found were Lutzomyia (Nyssomyia) intermedia, L. migonei, L. (N.) flaviscutellata, L. (Psychodopygus) ayrozai and L. (Lutzomyia) longipalpis. Five species were new records in Ilha Grande: L. (Sciopemyia) microps, L. termitophila, L. firmatoi, L. rupicola and L. (P.) ayrozai. Higher species richness was found inside forest areas, although potential leishmaniases vectors were present in deforested areas, peridomiciles and inside houses. Lutzomyia (N.) intermedia and L. migonei were the most abundant species. Females of L. migonei showed a high rate (10.3%) of natural infection by Leishmania (Viannia) sp., probably Leishmania (V.) braziliensis. The detection of leishmaniases transmission and potential vectors in Ilha Grande is of public health concern, especially because tourists are frequently visiting the island. Besides reinforcing the epidemiological importance of L. (N.) intermedia in Rio de Janeiro State, the role of L. migonei in cutaneous leishmaniasis transmission is highlighted with its high rate of Leishmania natural infection. The finding of L. (L.) longipalpis confirmed the human autochthonous case of visceral leishmaniasis from the

    Full Text Available This work intends to apply new ecological descriptors to a coastal marine area aiming to assess its environmental trophic status. This approach makes possible to identify relevant variables associated with eutrophication process applicable and valid worldwide. The aim of this work is to study the organic matter (OM quality and quantity, in terms of biopolymers, in Saquarema Lagoonal System (SLS located in Rio de Janeiro State (Brazil. Sediment samples collected in SLS were analyzed in this study for granulometric and geochemical data such as total organic carbon (TOC, total sulfur (TS and biopolimeric carbon (BPC concentrations, including proteins (PTN, carbohydrates (CHO and lipids (LIP. These data were combined with additional environmental parameters measured in water of the four linked lagoons that compose SLS. Data analyses allowed the identification of four distinct regions in SLS: an inner and impacted zone characterized by sediment particularly enriched in TOC, with lowest quality of OM most probably provided by contaminated effluents and rivers runoff; an outer-less impacted lagoonal area with relatively low TOC content and submitted to high hydrodynamic forces; an intermediate area characterized by transitional features between the two previously mentioned and a zone that is influenced mainly by salinity. The organic matter accumulation depends on the hydrodynamic conditions mostly governed by tidal currents. The quality of organic matter seems to be mainly influenced by the water renewal, rivers inputs and mangroves contributions as well as by the autochthonous lagoonal biological productivity. Results of this work indicate that the inner zone of SLS is being affected by eutrophication not necessarily caused by anthropic factors.

    Full Text Available Euglossine bee communities in small forest fragments of the Atlantic Forest, Rio de Janeiro state, southeastern Brazil (Hymenoptera, Apidae. Euglossine bees are important pollinators in forests and agricultural areas. Although the structure of their communities is critically affected by anthropogenic disturbances, little is known about these bees in small forest fragments. The objectives of this study were to analyze the composition, abundance, and diversity of euglossine bee species in nine small fragments of different phytophysiognomies of the Atlantic Forest in southeastern Brazil, and to identify the environmental variables that may be related to the species composition of these communities. Males were sampled quarterly from May 2007 to May 2009 with aromatic traps containing methyl cinnamate, vanillin, eucalyptol, benzyl acetate, and methyl salicylate. A total of 1558 males, belonging to 10 species and three genera of Euglossina were collected. The richness ranged from five to seven species per fragment. Euglossa cordata, E. securigera, Eulaema nigrita e E. cingulata were common to all fragments studied. The diversity differed significantly among areas, ranging from H' = 1.04 to H' = 1.65. The precipitation, phytophysiognomy, and altitude had the highest relative importance over the species composition variation. The results presented in this study demonstrate that small forest fragments are able to support populations of euglossine bee species, most of which are widely distributed and reportedly tolerant to open and/or disturbed areas and suggest that the conservation of such areas is important, particularly in areas that are regenerating and in regions with agricultural matrices where these bees can act as important pollinators

The attitudes of the most authoritative sports experts are analyzed. Various media discuss the performance of Russians in the Olympics of the third Millennium, the role and importance of psychology in modern sport and also in preparation of elite sport athletes for such important tournaments as the Olympic Games. The paper discusses fundamental differences of psychological preparation of the Russian and foreign athletes, comparative analysis of national team performances of Russia in the summer Olympics and Paralympic Games over the past 20 years, i.e. in 1996, 2000, 2004, 2008 and 2012. The paper analyses the strongest team performances on the global level in the latest Summer Olympic games and the probabilistic prediction of the performance results in the Summer Olympics in Brazil in reference with November doping scandal in the Russian Athletics Federation associated with charges of the Russian athletes in the mass doping followed by a loud dismissal of a number of sports officials and coaches, with two Russian athletes to be disqualified and stripped of their medals of London Olympics-2012, and also a RAF member in the IAAF to be suspended, which puts into question the possibility of Russian national athletics team participating in the next Olympics. The paper outlines current problematic issues the solution of which is urgent for the 21st Summer Olympics 2016 in Rio de Janeiro, Brazil, and should contribute to a fundamental change in the psychological, spiritual, moral atmosphere not only of an individual athlete, but for all Russian sport in general.

    Calls to address crack-cocaine use in Brazil among homeless and street-frequenting populations who are in urgent need of health services have questioned the capacity of the Brazilian Unified Health System to attend to the nation's most marginalized citizens. In recent years, Brazil has launched several actions to escalate care for substance users, yet many obstacles hindering accessibility and effectiveness of services remain. Paradoxically, these actions have been implemented in the context of a growing economic crisis, and expanding services for a population of poor and stigmatized substance users while cutting other government programs tends to elicit harsh criticism from citizens. In consequence of such prospects, this commentary aims to discuss barriers marginalized substance users face in accessing health services that are at risk of worsening with government cutbacks. Using Rio de Janeiro as an example, we explore two primary issues: the resource-strained, under-staffed and decentralized nature of the Brazilian Unified Health System and the pervading stigma that bars vulnerable citizens from official structures and services. Abandoning initiated government efforts to increase access to health services would risk maintaining vulnerable citizens at the margins of public structures, inhibiting the opportunity to offer this population humane and urgently needed treatment and care.

    The objective of this study was to assess the mortality profile related to SSc in the state of Rio de Janeiro, Brazil. We retrospectively examined all registered deaths in the region (2006-2015 period) in which the diagnosis of SSc was mentioned on any line of the death certificates (underlying cause of death [UCD], n = 223; non-UCD, n = 151). Besides the analysis of gender, age, and the causes of death, we also compared the mortality from UCDs between individuals whose death causes included SSc (cases) and those whose death causes did not include SSc (deceased controls). For the latter comparison, we used the mortality odds ratio to approximate the cause-specific standardized mortality ratio. We identified 1495 death causes among the 374 SSc cases. The mean age at death of the SSc cases (85% women) was significantly lower than that of the controls (n = 1,294,117) (58.7 vs. 65.5 years, respectively). The main death causes were circulatory system diseases, infections, and respiratory diseases (36%, 34%, and 21% of SSc cases, respectively). Compared to the deceased controls, there were proportionally more deaths among the SSc cases from pulmonary arterial hypertension, lung fibrosis, septicemia, gastrointestinal hemorrhage, other systemic connective tissue diseases, and heart failure (for death age causes in this predominantly non-Caucasian sample of SSc patients. Of interest, the percentage of infection-related deaths in our report was about three times higher than that in SSc studies with predominantly Caucasian populations.

    The context of first drug injection and its association with ongoing injecting practices and HCV (hepatitis C virus) infection were investigated. Injection drug users (IDUs) (N = 606) were recruited in "drug scenes" (public places, bars) in Rio de Janeiro, Brazil, interviewed, and tested for HCV. Sharing of needles/syringes was more prevalent at the first injection (51.3%) than at the baseline interview (36.8%). Those who shared syringes/needles at first injection were more likely to be currently engaged in direct/indirect sharing practices.

    The paper offers a historical analysis of the creation of the sector responsible for inaugurating and managing Rio de Janeiro's basic sanitary services, examining the period from the mid-nineteenth century, when sanitary issues were first posed, through the 1920s. The analysis centers on the relation between the service structure established by the state, on the one hand, and urban space, on the other, taking a particular look at the special interests involved in creation of this structure. Exploring the vast literature available on Rio de Janeiro's urban world at that time, the present text supplements this with an analysis focused above all on the architecting of Brazil's first policies on sanitation infrastructure.

    To assess the physical characteristics of public spaces designed for sport/physical activity/leisure in Rio de Janeiro, Brazil, and their relationship to the socioeconomic indicators. Public spaces (n = 38) spread across the city were evaluated between December 2011 and January 2012 using the Physical Activity Resource Assessment (PARA) instrument. Based on PARA results, a Quality Indicator (QI) was prepared and the sample was grouped into "High QI" and "Low QI" using a k-means clustering algorithm. The association between QI and the local Social Development Index (SDI) was tested using a Chi-square test. The average QI was 13.6 ± 4.91 and the median was equal to 13 points. The High QI group, composed of sites with a QI above median, reached 17.9 ± 2.35 points, while the Low QI group reached 9.3 ± 2.16 points. Pearson's Chi-square tests identified a significant association between QI and SDI when the value of SDI 0.7 was used as a criterion for separation (χ(2) = 17.84, p public spaces usually had a lower QI. Policies to encourage physical activity need to focus attention on the built environment also, particularly in socially vulnerable areas. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Some aspects of the ecology of the skink Mabuya agilis (Raddi, 1823 at the restinga habitat of Grumari, in Rio de Janeiro, Brazil are studied. Most of the lizards were first sighted on the ground, though a few were using perches (mainly cacti up to 30 cm high. Mean body temperature in activity was 33.1 ± 2.4ºC and was significantly correlated to air temperature. There was sexual dimorphism in size (snout-vent length - SVL, with females growing larger than males. Frequency of broken tails was high overall (83% and did not differ between sexes. Females and males are sexually mature at 49 mm and 47 mm SVL, respectively. Brood size averaged 3.2 ± 1.0 (range 1-5 and was positively and significantly related to female SVL (r = 0.65, p = 0.001. Relative clutch mass (RCM of seven gravid females averaged 0.250 ± 0.042, being relatively low compared to those of other congeners. The diet of M. agilis was composed basically of arthropods, with relatively large and soft-bodied arthropods such as spiders, caterpillars and homopterans being the most important prey. The results of our work confirm and expand the knowledge of ecological tendencies previously observed for M. agilis in other areas.

    Full Text Available Noroviruses (Norwalk-like viruses are an important cause of gastroenteritis worldwide. They are the most common cause of outbreaks of gastroenteritis in the adult population and occur in nursing homes for the elderly, geriatric wards, medical wards, and in hotel and restaurant settings. Food-borne outbreaks have also occurred following consumption of contaminated oysters. This study describes the application of a reverse transcription-polymerase chain reaction (RT-PCR assay using random primers (PdN6 and specific Ni and E3 primers, directed at a small region of the RNA-dependent RNA polymerase-coding region of the norovirus genome, and DNA sequencing for the detection and preliminary characterisation of noroviruses in outbreaks of gastroenteritis in children in Brazil. The outbreak samples were collected from children <5 years of age at the Bertha Lutz children's day care facility at Oswaldo Cruz Foundation (Fiocruz, Rio de Janeiro, that occurred between 1996 and 1998, where no pathogen had been identified. At the Bertha Lutz day care center facility, only Fiocruz's employee children are provided for, and they come from different social, economic and cultural backgrounds. Three distinct genogroup II strains were detected in three outbreaks in 1997/98 and were most closely related to genotypes GII-3 (Mexico virus and GII-4 (Grimsby virus, both of which have been detected in paediatric and adult outbreaks of gastroenteritis worldwide.

    Yellow fever virus is a mosquito-borne flavivirus that causes yellow fever, an acute infectious disease that occurs in South America and sub-Saharan Africa. Most patients with yellow fever are asymptomatic, but among the 15% who develop severe illness, the case fatality rate is 20%-60%. Effective live-attenuated virus vaccines are available that protect against yellow fever (1). An outbreak of yellow fever began in Brazil in December 2016; since July 2017, cases in both humans and nonhuman primates have been reported from the states of São Paulo, Minas Gerais, and Rio de Janeiro, including cases occurring near large urban centers in these states (2). On January 16, 2018, the World Health Organization updated yellow fever vaccination recommendations for Brazil to include all persons traveling to or living in Espírito Santo, São Paulo, and Rio de Janeiro states, and certain cities in Bahia state, in addition to areas where vaccination had been recommended before the recent outbreak (3). Since January 2018, 10 travel-related cases of yellow fever, including four deaths, have been reported in international travelers returning from Brazil. None of the 10 travelers had received yellow fever vaccination.

    Although the Rio de Janeiro State owns one of Brazilian most important natural gas reserves and is responsible for 40% of country's natural gas production, the option to increase the utilization of this form of energy, in Rio, has been unexpectedly delayed. The warning that soon there will be a lack of electric power has already been given, and Rio's industrial activity, which has been growing above national average, may suffer irretrievable damages from this scarcity. Brazil is not self-sufficient as regards PLG yet, this fuel is heavily subsidized which thwarts competition in the residential market, with presently existing systems for distributing piped gas. It becomes necessary to remove barriers for obtaining resources and for incorporating PETROBRAS parallel distribution system into the State system, thus supplying the conditions for accelerating large scale use of natural gas in Rio de Janeiro.

    Full Text Available As Rocky Mountain Spotted Fever is the most common tick-borne disease in South America, the presence of Rickettsia sp. in Amblyomma ticks is a possible indication of its endemicity in certain geographic regions. In the present work, bacterial DNA sequences related to Rickettsia amblyommii genes in A. dubitatum ticks, collected in the Brazilian state of Mato Grosso, were discovered. Simultaneously, Paracoccus sp. was detected in aproximately 77% of A. cajennense specimens collected in Rio de Janeiro, Brazil. This is the first report of Paracoccus sp. infection in a specific tick population, and raises the possibility of these bacteria being maintained and/or transmitted by ticks. Whether Paracoccus sp. represents another group of pathogenic Rhodobacteraceae or simply plays a role in A. cajennense physiology, is unknown. The data also demonstrate that the rickettsial 16S rRNA specific primers used forRickettsia spp. screening can also detect Paracoccus alpha-proteobacteria infection in biological samples. Hence, a PCRRFLP strategy is presented to distinguish between these two groups of bacteria.

    Full Text Available OBJECTIVE: To evaluate density, parity rates, daily survival and longevity of natural populations of Culex quinquefasciatus in three neighborhoods with distinct socio-economic and infrastructure profiles. METHODS: Mosquito collections of the Culex quinquefasciatus species were performed weekly during two four month periods, from August to November 2008 (spring and March to June 2009 (fall, in a favela (slum, a suburban area and a middle class area of Rio de Janeiro, Southeastern Brazil. Collections were performed with backpack aspirators, in 20 randomly selected houses in each area per week, during 15-20 minutes per house. Ovaries were removed from captured females and classified as initial, intermediary or final stage. Furthermore, females were dissected for determination of parity based on the condition of the tracheal system. Mosquito survival rate and longevity were estimated on a per month basis for each neighborhood. RESULTS: We collected a total of 2,062 Culex quinquefasciatus, but monthly vector density was not correlated with temperature and rainfall. We dissected the ovaries of 625 Culex quinquefasciatus, and overall, there was a higher proportion of nulliparous females during the dryer months, while gravid females were more frequent in rainy months. In the middle class neighborhood, the parity rate reached up to 93.75% with survivorship of 0.979. Lower parity and survival rates were obtained in the suburban area (as low as 36.4% parity and 0.711 daily survival. Up to 84.7% of Culex quinquefasciatus females could survive the eight day period needed to complete West Nile Virus incubation. CONCLUSIONS: The survival rate of Culex quinquefasciatus varied significantly between the neighborhoods. This suggests that vectorial capacity and disease transmission risk may vary greatly between different urban areas, which is potentially useful information for vector control programs.

    Full Text Available Estuaries enhance growth and maximize the survivorship of initial development stages of fish species, functioning as nursery grounds for many species. However, estuaries throughout the world host a wide variety of human activities, and fish communities can be severely impacted. Protection of aquatic biodiversity and proper management of these coastal systems require robust tools to assess habitat integrity and ecological quality status. Thus, the present study investigated the use of fish larvae as indicators of estuarine ecosystem condition in Brazil, testing the hypothesis that estuaries with different human impacts and environmental conditions carry distinct larval fish assemblages. For this, four estuaries were analysed with: similar environmental conditions (the same water mass surveyed, similar pool of species (the same geographical region and no seasonal influences (different periods analysed separately. Surveys were conducted in Macaé, São João, Bracuí and Perequê-Açu estuaries located in Rio de Janeiro State, Brazil. Sampling surveys were conducted every two months between May 2013 and March 2015. All samples were taken in the estuary middle region (salinity 15-25 during nightly ebb tides. At each estuary, ichthyoplankton subsurface tows were perfomed using a Bongo net. Water parameters were measured by a multiparameter probe and surface water samples collected for further analytical analyses. Fish larvae were identified and species were assigned into functional guilds. The water conditions were assessed based on water temperature, pH, chlorophyll a, dissolved oxygen and total particulate matter. Faecal coliforms, nutrient load (NO3, NO2, NH3, PO4, SiO3 and presence/absence of dams, dredging and mangroves were used as anthropogenic pressure descriptors. The species composition and ecological guilds of Macaé and Perequê-Açu differed significantly of São João and Bracuí, separating the impacted versus non-impacted estuaries

    Full Text Available ABSTRACT The present work aimed to report the histopathological findings verified in lungs of hawksbill turtles (Eretmochelys imbricata retrieved from the coasts of the states of Espírito Santo and Rio de Janeiro, Brazil. Between the years 2010 and 2014, 29 E. imbricata individuals were found stranded on the coasts, already dead or dying during treatment. Lung samples of all specimens were collected during necropsies, fixed in 10% neutral buffered formalin, subjected to routine histological processing and classified histomorphologically. The findings revealed that 37.93% of the specimens presented lung lesions. Of these, 90.91% were rescued alive and 9.09% were found dead; 63.63% were females and 36.37% were males. The mean weight was 5.44 Kg and the mean length 39 cm, characterizing young individuals. The animals originated from São Francisco de Itabapoana - RJ, Aracruz - ES, São Mateus - ES, Guarapari - ES, Linhares - ES, Itapemirim - ES, and Anchieta - ES. Macroscopic analysis revealed presence of foam, hyperemia, nodules in the parenchyma, cyst and caseous material. Microscopic examination evidenced heterophilic bronchopneumonia, parasitic granulomatous pneumonia caused by spirorchiids, bacterial granulomatous pneumonia, fungal granulomatous pneumonia, and congestion. It was concluded that juvenile specimens of Eretmochelys imbricata, females and males, originated from the states of Espírito Santo and Rio de Janeiro and found stranded both alive or dead, have significant lung lesions, mainly inflammatory ones, associated or not with infectious agents.

    Full Text Available The concentrations of twenty-five elements (Al, As, Ba, Bi, Ca, Cd, Cr, Cu, Fe, Ga, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Rb , Sb, Se, Sn, Sr, V and Zn were determined in three edible mushrooms, Shiitake (Lentinula edodes, Black Shimeji (Pleurotus ostreatusi and Cardoncello (Pleurotus eryngyii from Petrópolis, Rio de Janeiro, Brazil. Samples were collected along the year 2010 and their preparations were made after drying, milling, an acid pre-digestion and a decomposition procedure in a muffle furnace. The analytical techniques employed for the elements determination were Mass Spectrometry with Inductively Coupled Plasma and Flame Atomic Absorption Spectrometry. Two certified reference materials, Apple Leaves and Mussel Tissue, were used for the evaluation of the analytical procedure and recovery values around 98% were obtained. The results showed that the analyzed mushrooms have high levels of Cu, Fe, K, Mg, Mn and Zn containing more than 30% the recommended daily intake for these nutrients according to Brazilian legislation. These mushrooms presented a very low ratio Na/K. Regarding the levels of some contaminants, the mushrooms had concentrations of Cd, Pb and As below the recommended maximum limits allowed by Brazilian legislation.

    Full Text Available The age-specific prevalence of antibodies to hepatitis A virus (anti-HAV was determined in two different population groups with low socio-economic status from Rio de Janeiro city, Brazil, whose serum samples were collected 17 years apart (Population 1, 1978; Population 2, 1995. In Population 2, analysis of the anti-HAV prevalence was also carried out with respect to environmental factors. Population 1 was composed of 520 stored sera collected from the umbilical cord of term neonates and children aged 1 month to 6 years. In population 2, 720 serum samples were collected from children and adolescents with ages ranging from 1 to 23 years. The overall prevalence rate of anti-HAV in Population 1 and Population 2 was 65.6% and 32.1%, respectively. In Population 1, the anti-HAV prevalence reached 88% at the age of 3, while in Population 2, it increased from 4.5% in children under the age of 3 to 66% in the group of adolescents over the age of 14. The low exposure to HAV infection in younger children from Population 2 could be a result of improved environmental hygiene and sanitation, as demonstrated by the presence of piped water, waste and sewage disposal systems in most houses from this population group. These findings indicate a possible change in the prevalence of hepatitis A in Rio de Janeiro

METHODS: Plasma samples from 1 101 consecutive blood donations made in November 2000 at HEMORIO, the largest blood bank in the state of Rio de Janeiro, were tested for measles immunoglobulin G, using a commercial enzyme immunoassay and a plaque reduction neutralization test. We calculated the proportion (and 95% confidence interval (CI of samples seronegative for measles antibody for the total sample of blood donors and also for subgroups categorized by age, sex, neighborhood of residence, education, and occupation. We used the chi-square test to assess the statistical significance of differences in proportions and linear trends in proportions. RESULTS: Of the total group of blood donors, 6.9% of them (95% CI: 5.4%­8.4% were seronegative for measles. Women had a higher proportion (10.1%; 95% CI: 6.8%­13.4% of seronegative results than did men (5.6%; 95% CI: 4.0%­7.2%.

    2004-01-01

    In parallel to Brazil's recent supply crisis, the privatization process of its power sector has drastically reshaped the nation's energy matrix. From a profile based mainly on hydro-power generation, this sector is being reshaped through a thermo-power plant construction program whose environmental repercussions will certainly be felt over the next few years. This paper offers a description of the thermo-power segment currently in operation, under construction and on the drawing board in Brazil, followed by the results of a diagnosis of the control and monitoring of the gas emissions by this segment. The methodology used for the exploratory analysis and to prepare the diagnosis consists of surveys through questionnaires completed by companies owning the thermo-power plants. After consolidating, processing and analyzing the findings reached through the replies sent in by the companies, it is concluded that thermo-power plants currently in operation lack control systems that would help reduce atmospheric pollution, and are not equipped with monitoring systems for these emissions. The thermo-power plants currently under construction and on the drawing board indicate a trend towards including these systems in their project designs, due to more stringent licensing processes

    Full Text Available Malignant hyperthermia (MH is a pharmacogenetic disease triggered by volatile anesthetics and succinylcholine. Deaths due to MH have been reported in Brazil. The first Malignant Hyperthermia Diagnostic and Research Center in Latin America was inaugurated in 1993 at the Federal University of Rio de Janeiro, Brazil. The center followed the diagnostic protocols of the North America MH Group, in which the contractures of biopsies from the vastus lateralis muscle are analyzed after exposure to caffeine and halothane (CHCT. CHCT was performed in individuals who survived, their relatives and those with signs/symptoms somewhat related to MH susceptibility (MHS. Here, we report data from 194 patients collected over 16 years. The Southeast (N = 110 and South (N = 71 represented the majority of patients. Median age was 25 (4-70 years, with similar numbers of males (104 and females (90. MHS was found in 90 patients and 104 patients were normal. Abnormal responses to both caffeine and halothane were observed in 59 patients and to caffeine or halothane in 20 and 11 patients, respectively. The contracture of biopsies from MHS exposed to caffeine and halothane was 1.027 ± 0.075 g (N = 285 and 4.021 ± 0.255 g (N = 226, respectively. MHS was found in patients with either low or high blood creatine kinase and also, with a low score on the clinical grading scale. Thus, these parameters cannot be used with certainty to predict MHS. We conclude that the CHCT protocol described by the North America MH Group contributed to identification of MHS in suspected individuals at an MH center in Brazil with 100% sensitivity and 65.7% specificity.

    Full Text Available OBJECTIVE: To assess the additional cost of incorporating the detection and treatment of retinopathy of prematurity (ROP into neonatal care services of Brazil's Unified Health System (SUS. METHODS: A deterministic decision-tree simulation model was built to estimate the direct costs of screening for and treating ROP in neonatal intensive-care units (NICUs, based on data for 869 preterm infants with birth weight less than 1 500 g examined in six governmental NICUs in the capital city of Rio de Janeiro, where coverage was 52% and 8% of infants were treated. All of the parameters from this study were extrapolated to Brazilian newborn estimates in 2010. Costs of screening and treatment were estimated considering staff, equipment and maintenance, and training based on published data and expert opinion. A budget impact analysis was performed considering the population of preterm newborns, screening coverage, and the incidence of treatable ROP. One- and two-way sensitivity analyses were performed. RESULTS: In Rio de Janeiro, unit costs per newborn were US$ 18 for each examination, US$ 398 per treatment, and US$ 29 for training. The estimated cost of ROP diagnosis and treatment for all at-risk infants NICUs was US$ 80 per infant. The additional cost to the SUS for one year would be US$ 556 640 for a ROP program with 52% coverage, increasing to US$ 856 320 for 80% coverage, and US$ 1.07 million or 100% coverage. CONCLUSIONS: The results of this study indicate that providing ROP care is affordable within the framework of the SUS in Brazil, and might be feasible elsewhere in Latin America, considering the evidence of the effectiveness of ROP treatment and the social benefits achieved.

    Full Text Available The influence of sedimentation and turbidity caused by the pluviometric precipitation and by the Paraiba do Sul River during the summer was investigated on an artificial reef along the north coast of Rio de Janeiro, Brazil. Four recruitment and four cumulative plates were removed monthly (January 2002 to February 2003 from the external surface of the concrete reef modules. Empty space was not a limiting factor the recruitment. Turnover rate and structural difference index were higher in the first months and reflected low change in the species dominance during almost the entire study period. The high correlation between the precipitation and the empty space suggested that rain influence the recruitment and the succession. The recruitment was possible despite stress factors such as sedimentation, turbidity, abrasion, strong bottom currents and a lack of natural consolidated substrate. Changes in the community structure reflected the substrate colonization history of a few resistant species and their subsequent interactions.A influência da sedimentação e da turbidez causadas pela precipitação pluviométrica e vazão do rio Paraíba do Sul nos meses de verão foi investigada em um recife artificial na costa norte do Estado do Rio de Janeiro, Brasil. Quatro placas de recrutamento e quarto placas de sucessão eram retiradas mensalmente (Janeiro de 2002 a Fevereiro de 2003 da superfície externa de módulos recifais de concreto. Espaço vazio não foi um fator limitante para o recrutamento. A taxa de substituição de espécies e o grau de diferença na estrutura da comunidade foram superiores nos meses iniciais, refletindo as reduzidas mudanças na dominância das espécies durante o período de estudo. A alta correlação entre precipitação e espaço vazio sugere a influência da precipitação no recrutamento e sucessão dos organismos. Recrutamento foi possível mesmo com fatores estressantes como sedimentação, turbidez, correntes de fundo

    Sporotrichosis is endemic in Rio de Janeiro, Brazil, and cases have been reported to be associated with HIV. This article describes the clinical manifestations and evolution of sporotrichosis in HIV-positive patients and constitutes the largest case series reported to date. There were 21 HIV-positive patients with sporotrichosis diagnosed by the recovery of the etiologic agent from 1999-2009. Sixteen patients (76.2%) were men and five (23.8%) were women, with a mean age of 41.2 years. Seven of these individuals were previously unaware of their HIV infection. Mean CD4 count was 346.4 cells/μl. The most frequent clinical presentations of sporotrichosis in these patients were the lymphocutaneous and disseminated form (seven patients each, 33.3%), followed by the widespread cutaneous form in five (23.8%), and fixed form in the remaining two (9.5%). In patients with the disseminated forms, clinical manifestations involved the skin in six, mucosa (nasal, oral, or conjunctival) in four, bone in two, and meninges in two. Eleven (52.4%) patients received itraconazole and eight (38.1%) amphotericin B contributing to an overall cure rate of 81%. Spontaneous cure was observed in one patient. The clinical forms of sporotrichosis varied according to the patients' immune status. The results demonstrate the importance of sporotrichosis as an opportunistic infection associated with AIDS in countries where the mycosis occurs.

    Full Text Available The aim of this research is to characterize the mortars of the Rui Barbosa House Museum, built in 1850, in the city of Rio de Janeiro, Brazil, using X-ray diffraction (XRD, gel-CSH determination, Fourier Transform Infrared spectrometry (FTIR, Wavelength-Dispersive X-ray Fluorescence spectrometry (WDXRF, Thermo gravimetric analysis (TG-DTG, and granulometric analysis. Also, petrographic and physical characteristics such as porosity, water absorption, and apparent density of the mortars were used to identify the raw materials employed in their preparation. Mineralogical associations found are similar (quartz, calcite, kaolinite, microcline, muscovite, and albite for the majority of samples and only vary in their proportions; the most prominent phases are quartz and calcite. The collected data, indicating that the binder is hydrated lime, lead us to conclude that the analyzed samples are lime mortars, discarding the possibility of cement as the binder material. Two samples, located on the corner of the building, which underwent repairs, present a differentiated behavior, with high levels of dolomite and the presence of pozzolanic material, with greater water absorption and higher density, indicating the use of a different mortar type. In addition, it was verified that the WDXRF and XRD methods are able to determine the trace element composition with comparable precision with respect to the methodological approach proposed by Teutonico (1988. In addition, it has been verified that the major pollutant causing degradation of building are sulfur emitted by the vehicles and saline spray.

  12. On norms and bodies: findings from field research on cosmetic surgery in Rio de Janeiro, Brazil.

    2010-05-01

    Brazil has the second highest rate of cosmetic surgery worldwide, provided in a large number of public and private clinics and hospitals, especially in the southeast. This qualitative field research in Rio de Janeiro included participant observation and in-depth interviews with 18 women cosmetic surgery patients, 10 key informants (e.g. psychologists and sociologists) and 12 plastic surgeons. Fifteen of the women were either pre- or post-operative; three had not decided whether to have surgery. When asked about their motivations and expectations of the surgery, the majority of the women said they wanted to be "normal". Most of the surgeons said they acted as empathic companions from decision-making through surgery and beyond. Many of the key informants were critical of what was happening to medical ethics in relation to cosmetic surgery. With the growth in a consumer culture, they saw ethics in medicine becoming more bendable and subject to the "law" of the market. The cult of the body has become a mass phenomenon and taken on an important social dimension in a society where norms and images are broadcast widely by the media. The trend towards body-modification by cosmetic surgery at an early age is increasing dramatically. What demands critical thinking and further investigation are the consequences of cosmetic surgery for physical and mental health. Copyright 2010 Reproductive Health Matters.

    Full Text Available This paper analyzed the solid wastes of anthropogenic origin obtained from the stomach contents of juvenile green turtles, Chelonia mydas, on the eastern Rio de Janeiro state coast, southeastern Brazil (22º50’S – 23º00’S. Between June 2009 and May 2010, the stomach contents of 49 specimens stranded on beaches were analyzed. Solid wastes were recorded in 29 stomach contents (59.2% and more than one category of wastes was found out in 22 samples. Plastic bags, categorized as flexible plastic materials, achieved the greatest occurrence frequency (96.5%. Perhaps, these wastes came from the disposal of garbage bags, raffia bags, commercial shop bags and various packaging. Wastes related to manufacture of fishing equipment were also often reported, such as nylon yarns, rubber, ropes, Styrofoam, and fishhooks. The region is an area of regular occurrence of C. mydas and the relatively large intake of solid wastes deposited in the environment poses a risk to the conservation of this species.

    Full Text Available SUMMARY Chagas disease (CD is an endemic anthropozoonosis from Latin America of which the main means of transmission is the contact of skin lesions or mucosa with the feces of triatomine bugs infected by Trypanosoma cruzi. In this article, we describe the first acute CD case acquired by vector transmission in the Rio de Janeiro State and confirmed by parasitological, serological and PCR tests. The patient presented acute cardiomyopathy and pericardial effusion without cardiac tamponade. Together with fever and malaise, a 3 cm wide erythematous, non-pruritic, papule compatible with a "chagoma" was found on his left wrist. This case report draws attention to the possible transmission of CD by non-domiciled native vectors in non-endemic areas. Therefore, acute CD should be included in the diagnostic workout of febrile diseases and acute myopericarditis in Rio de Janeiro.

    The aims of the present study were to identify and describe the occurrence of nematode parasites in the gonads of bluefish Pomatomus saltatrix from off the coast of the state of Rio de Janeiro, Brazil. Only females were found to be parasitized by the nematodes, which were identified as P. saltatrix using morphological, morphometric and molecular data. Infection of female bluefish by this nematode had the following values: prevalence, 48.7%; mean intensity, 2.6; mean abundance, 1.3; and range of infection, 1-10 specimens. Histopathological examination of transverse and longitudinal sections of the parasitized ovaries showed nematodes at different stages of development among oocytes, but no indication of any associated inflammatory reaction. The presence of nematodes in the ovaries of bluefish is an important indication of fish hygiene, and parasitized fish are usually rejected by consumers because of their repugnant appearance.

    The tribe Vatellini Sharp, 1882 is composed of 55 species divided in two genera. Even though a recent revision of the tribe was made, Vatellini of the new world are weakly explored with great gaps in the distributions of species. In Brazil the knowledge is based only on a few localities. In this work two new species are described and illustrated, Vatellus caissara sp. nov. and Vatellus yanomami sp. nov.; new records are given for Brazil: Vatellus maculosus Miller, 2005 in the state of Mato Grosso, Derovatellus lentus (Wehncke, 1876) in Amazonas, Pará and Rio de Janeiro, Vatellus lateralis (Sharp, 1882) in Alagoas, Ceará, Espírito Santo, Pará, Pernambuco and Rio Grande do Sul, Vatellus sahlbergi (Sharp, 1882) in Rio de Janeiro, and Vatellus tarsatus (Laporte, 1835) in Pará. A checklist with all species of Vatellini occurring in Brazil is provided and steps for identification of the new species are added in the key of Miller (2005).

    Access to antiretroviral therapy (ART), universally provided in Brazil since 1996, resulted in a reduction in overall morbidity and mortality due to AIDS or AIDS-related complications, but in some municipalities of Rio de Janeiro, AIDS incidence remains high. Public health surveillance remains an invaluable tool for understanding current AIDS epidemiologic patterns and local socioeconomic and demographic factors associated with increased incidence. Geographically Weighted Poisson Regression (GWPR) explores spatial varying impacts of these factors across the study area focusing attention on local variations in ecological associations. The set of sociodemographic variables under consideration revealed significant associations with local AIDS incidence and these associations varied geographically across the study area. We find the effects of predictors on AIDS incidence are not constant across the state, contrary to assumptions in the global models. We observe and quantify different local factors driving AIDS incidence in different parts of the state. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    2010-01-01

    This article analyses the connections between the ideas and principles of American city planning from 1920 with those articulated by Brazilian city planners in the 1930s and implemented by the administration of the City of Rio de Janeiro, then the capital of Brazil, notably during the period of the Estado Novo [The New State] from 1937 to 1945. In a period characterized by the centralization of political power and the concentration of decision-making in the hands of the president and the state, the City of Rio de Janeiro undertook a series of restructuring projects which utilized new forms of administration and organization. This article explores the links between urban planning in Brazil and the USA that were a notable feature of these projects. It examines particular requirements set down in city plans, city planning commissions and funding for urban activities, such as 'excess condemnation', by focusing upon articles and books written by four Brazilian engineers and proposals put forward by the American City Planning Institute, detailed in the proceedings of the National Conference on City Planning, in the periodical, City Planning and works by affiliated authors.

    Full Text Available This article describes the main issues regarding clinical cancer research in Brazil, including both the opportunities and the hurdles. Scientists and clinicians in this field had the opportunity to talk to regulatory agencies and to the Health Ministry representative at a meeting held in the State of Rio de Janeiro, Brazil, in April 2014. Our conclusions are that we do indeed have opportunities; however, we need to move forward regarding partnerships between academia and industry, increase the availability of funding, and provide easier navigation through the regulatory processes.

    Surveys in the coastal sandy plains (restingas) of Rio de Janeiro have shown a great richness of galls. We investigated the galling insects in two preserved restingas areas of Rio de Janeiro state: Parque Estadual da Costa do Sol and Reserva Particular do Patrimônio Natural Fazenda Caruara. The collections were done each two months, from June 2011 to May 2012. We investigated 38 points during 45 minutes each per collection. The galls were taken to the laboratory for rearing the insects. A total number of 151 insect galls were found in 82 plant species distributed into 34 botanic families. Most of the galls occurred on leaves and the plant families with the highest richness of galls were Myrtaceae and Fabaceae. All the six insect orders with galling species were found in this survey, where Cecidomyiidae (Diptera) was the main galler group. Hymenoptera and Thysanoptera were found as parasitoids and inquilines in 29 galls. The richness of galls in the surveyed areas reveals the importance of restinga for the composition and diversity of gall-inducing insect fauna.

    A radioisotope production laboratory has been installed at Instituto de Engenharia Nuclear in Rio de Janeiro. It is intended primarily for processing short-lived radioisotopes produced by a multiparticle, variable energy, isochronous, compact CV-28 Cyclotron and for preparation of radiopharmaceuticals and labelled molecules. Carrier-free iodine-123, indium-111, thalium-201, bromine-77 and gallium-67 with high purity have been produced. An irradiated target transport system has been built. Special targets that can dissipate high surface power densities are being developed. Each radioisotope is processed in a remotely controlled cell equiped with electric and pneumatic systems as well as manipulators ans tongs. Quality control is achieved by atomic absorption spectrophotometry, spot tests, gamma-ray spectroscopy and thin-layer chromatography. Biological tests in mice have confirmed the good quality of the radiopharmaceuticals. (Author) [pt

    This article presents the partial results of a multicenter, qualitative study, which involved seven Latin-American countries and Canada. The results presented refer to Northern Rio de Janeiro (city), Brazil. The objective of the study was to describe the perspective of relatives/acquaintances of illicit drug users about protective and risk factors, prevention initiatives, treatment services, and legal aspects regarding illicit drugs. Interviews were performed with 99 individuals, who reported being affected by their relationship with an illicit drug user (relative or acquaintance), approaching their perspectives regarding the key-domains. Most participants were women (73.7%); relatives who used drugs were mostly men (78.2%); the most consumed drug was marijuana (77.8%). The highlighted protective factor was having recreational-sports activities in the community (88.9%), and the risk factor was curiosity for trying something new (94.4%). The main treatment services were Church Groups (51.5%), and participants stated that laws should be more punitive (82.8%). In conclusion, this information is essential to fight against drug use/abuse, showing that there is a need for actions that consider different perspectives at different levels.

    HIV-1 CRF02_AG is responsible for at least 8% of the HIV-1 infections worldwide and is distributed mainly in West Africa. CRF02_AG has recently been reported in countries where it is not native, including Brazil. In a previous study including 10 CRF02_AG Brazilian samples, we found at least four independent introductions and two autochthonous transmission networks of this clade in Brazil. As more CRF02_AG samples have been identified in Brazil, we performed a new phylogeographic analysis using a larger dataset than before. A total of 20 Brazilian (18 from Rio de Janeiro and two from São Paulo) and 1,485 African HIV-1 CRF02_AG pol sequences were analyzed using maximum likelihood (ML). The ML tree showed that the Brazilian sequences were distributed in five different lineages. The Bayesian phylogeographic analysis of the Brazilian and their most closely related African sequences (n = 212) placed the origin of all Brazilian lineages in West Africa, probably Ghana, Senegal, and Nigeria. Two monophyletic clades were identified, comprising only sequences from Rio de Janeiro, and their date of origin was estimated at around 1985 (95% highest posterior density: 1979-1992). These results support the existence of at least five independent introductions of the CRF02_AG lineage from West Africa into Brazil and further indicate that at least two of these lineages have been locally disseminated in the Rio de Janeiro state over the past 30 years.

    Full Text Available OBJECTIVES: to evaluate infant mortality in very low birth weight newborns from a public hospital in Rio de Janeiro, Brazil (2002-2006. METHODS: a retrospective cohort study was performed using the probabilistic linkage method to identify infant mortality. Mortality proportions were calculated according to birth weight intervals and period of death. The Kaplan-Meier method was used to estimate overall cumulative survival probability. The association between maternal schooling and survival of very low birth weight infants was evaluated by means of Cox proportional hazard models adjusted for: prenatal care, birth weight, and gestational age. RESULTS: the study included 782 very low birth weight newborns. Of these, (28.6% died before one year of age. Neonatal mortality was 19.5%, and earlyneonatal mortality was 14.9%. Mortality was highest in the lowest weight group (71.6%. Newborns whose mothers had less than four years of schooling had 2.5 times higher risk of death than those whose mothers had eight years of schooling or more, even after adjusting for intermediate factors. CONCLUSIONS: the results showed higher mortality among very low birth weight infants. Low schooling was an independent predictor of infant death in this low-income population sample.

    Endocrine disrupting compounds (EDCs) can be found in domestic sewage, wastewater treatment plant effluents, natural water, rivers, lakes and in the marine environment. Jurujuba Sound, located in the state of Rio de Janeiro, Southeastern Brazil, receives untreated sewage into its waters, one the main sources of aquatic contamination in this area. In this context, the aim of the present study was to evaluate the estrogenic potential of water sampled from different depths and from areas with differential contamination levels throughout Jurujuba Sound. Water quality was evaluated and acute toxicity assays using Allviibrio fischeri were conducted, while estrogenic activity of the water samples was determined by a Yeast Estrogen Screening assay (YES). Water quality was mostly within the limits established for marine waters by the Brazilian legislation, with only DOC and ammoniacal nitrogen levels above the maximum permissible limits. No acute toxicity effects were observed in the Allivibrio fisheri assay. The YES assay detected moderate estrogenic activity in bottom water samples from 3 sampling stations, ranging from 0.5 to 3.2ngL -1 , as well as in one surface water sample. Estrogenic activity was most frequently observed in samples from the bottom of the water column, indicating adsorption of estrogenic compounds to the sediment. Copyright © 2017 Elsevier Inc.

    Freshwater lagoons comprise important coastal ecosystems and natural buffers between urbanized land areas and open ocean in the Rio de Janeiro State, Brazil. Studies of sediment and water chemistry, zooplankton and bacterial communities to assess the extent of anthropogenic disturbance are available. Here we contribute with an organic-geochemical approach supplemented by some microbiological aspects to complete the characterization of these lagoonal ecosystems. Bulk organic matter and extractable lipids (aliphatic hydrocarbons, alcohols and fatty acids, sterols) were investigated from two locations per lagoon: at the seaward site and landward ends - and at two depth intervals (0-3 and 3-6 cm) per site. Urbanized Imboacica Lagoon received increased anthropogenic input over the most recent years represented by the topmost 3 cm of sediment, whereas deeper sediment layers are less affected by human influence. Eutrophication or nutrient availability favored enhanced algal/cyanobacterial growth. In remote Cabiúnas and Comprida Lagoons pristine conditions are preserved. Organic matter from vascular plants dominates (chain length of free lipids up to C36), which is exceptionally well preserved by acidic lagoonal waters. Differentiation between landward and seaward sites in these two lagoons is less well established due to much smaller surface/volume to catchment ratios. No anthropogenic influences are yet detectable in sediments of Cabiúnas and Comprida Lagoons.

    Antiretroviral (ARV) resistance mutations in human immunodeficiency virus type 1 (HIV-1) infection may reduce the efficacy of prophylactic therapy to prevent mother-to-child transmission (PMTCT) and future treatment options. This study evaluated the diversity and the prevalence of transmitted drug resistance (TDR) in protease (PR) and reverse transcriptase (RT) regions of HIV-1 pol gene among 87 ARV-naive HIV-1-infected pregnant women from Rio de Janeiro, Brazil, between 2012 and 2015. The viral diversity comprised HIV-1 subtypes B (67.8%), F1 (17.2%), and C (4.6%); the circulating recombinant forms 12_BF (2.3%), 28/29_BF, 39_BF, 02_AG (1.1% each) and unique recombinants forms (4.5%). The overall prevalence of any TDR was 17.2%, of which 5.7% for nucleoside RT inhibitors, 5.7% for non-nucleoside RT inhibitors, and 8% for PR inhibitors. The TDR prevalence found in this population may affect the virological outcome of the standard PMTCT ARV-regimens, reinforcing the importance of continuous monitoring.

    Zika virus infection was declared a public health emergency of international concern in February 2016 in response to the outbreak in Brazil and its suspected link with congenital anomalies. In this study, we use notification data and disease natural history parameters to estimate the basic reproduction number (R 0) of Zika in Rio de Janeiro, Brazil. We also obtain estimates of R 0 of dengue from time series of dengue cases in the outbreaks registered in 2002 and 2012 in the city, when DENV-3 and DENV-4 serotypes, respectively, had just emerged. Our estimates of the basic reproduction number for Zika in Rio de Janeiro based on surveillance notifications (R 0 = 2·33, 95% CI: 1·97-2·97) were higher than those obtained for dengue in the city (year 2002: R 0 = 1·70 [1·50-2·02]; year 2012: R 0 = 1·25 [1·18-1·36]). Given the role of Aedes aegypti as vector of both the Zika and dengue viruses, we also derive R 0 of Zika as a function of both dengue reproduction number and entomological and epidemiological parameters for dengue and Zika. Using the dengue outbreaks from previous years allowed us to estimate the potential R 0 of Zika. Our estimates were closely in agreement with our first Zika's R 0 estimation from notification data. Hence, these results validate deriving the potential risk of Zika transmission in areas with recurring dengue outbreaks. Whether transmission routes other than vector-based can sustain a Zika epidemic still deserves attention, but our results suggest that the Zika outbreak in Rio de Janeiro emerged due to population susceptibility and ubiquitous presence of Ae. aegypti.

    This work presents the results of a dose survey performed for paediatric patients and carried out in two large paediatric public hospitals in Rio de Janeiro city. The entrance surface dose (ESD) and the effective dose (ED) were evaluated for chest, skull, abdomen, lumbar spine, cervical spine and pelvis in antero-posterior (AP), postero-anterior (PA) and lateral (LAT) projections. For each examination, four age groups 0-1, 1-5, 5-10 and 10-15 years were studied. The DoseCal software was used to calculate these doses. Wide variations for the same type of examination and projection have been detected. These variations were evident, in Brazil, from previous work. In spite of the present results being still preliminary, they can give an idea of what paediatric ESDs are like in Brazil. Also, with respect to the entrance surface dose, some of the results are above the reference levels, which cause high ED, as well. On the other hand, the wide range of ESD reflects the disparity of radiographic techniques and demonstrates that the ALARA principle is not being applied in Brazilian hospitals and becomes a concern in terms of public health

    Checklist of Social Wasps (Vespidae: Polistinae in Two Green Urban Areas in the Municipality of Barra Mansa, Rio de Janeiro, Brazil Abstract. New concepts on city planning and urbanization have progressively encouraged the creation and maintenance of public or private green areas, which are important feeding and shelter zones for several species of social wasps. However, in spite of the sampling effort and representativeness of southeastern Brazil, knowledge of richness and abundance of social wasps in Rio de Janeiro is still poor. The present study aimed at inventorying the fauna of social wasps in urban phytophysiognomies in downtown Barra Mansa, state of Rio de Janeiro, within the campus of Barra Mansa University. We sampled two areas for 12 months - a human-modified grassland and a reforested area, through active search with insect nests, Möericke traps, and aromatic traps. We collected 148 wasps of three tribes, four genera, and 17 species. Through active search we recorded 70.7% of the species sampled. The tribe Epiponini showed the highest species richness, and Polybia chrysothorax Lichtenstein and Polybia erythrothoraxla Richards were recorded for the first time in the state of Rio de Janeiro. In the anthropic field it was observed greater diversity (H’ = 1,890, equitability (J = 0,7605, and minor dominance (D(1/D = 0,2124, while in the reforested area was obtained H’ = 1,582, J = 0,6366 e D(1/D = 0,3465. The configuration and size of the reforested area in the campus Barra Mansa (UBM are insufficient elements to restrict the movement of species or segregate communities when considering the anthropic field, thereby still allowing that species could also be sampled between the areas.

    The management of solid residues has, in recent decades, been a source of concern for public administrators the world over. Experiments in the sustainable use of such residues are highly relevant in social and environmental terms, stimulating widespread interest and debate, with considerable research going into sustainability projects. In many areas, however, adequate public funding for sustainable-use projects is hard to come by. One of the major reasons for this is that public authorities, particularly in times of financial constraints, are reluctant to invest in undertakings in which the economic returns are difficult to quantify. Official scrutiny of the expenditures of public authorities is also normally heavily influenced by cost-benefit analyses. The specific objective of this article is to show that putting solid domestic residue (household solid waste) to sustainable use is capable of generating economic returns, as well as environmental benefits for society as a whole. These economic returns can be set out in financial statements, which may, in turn, be used to justify expenditures by public authorities on sustainable-use projects and as a basis for further investment in such incentives. We drew on the findings of existing research into sustainable use, undertaken by the Municipal Urban Cleaning Company in the city of Rio de Janeiro, Brazil, to establish a conceptual framework for setting out the economic results of the collection of household solid waste.

    In developing countries, traditional sources of employment and work practices have changed rapidly and work environment has appeared as an important factor associated with an increased prevalence of mental disorders in these countries. To investigate the association between job strain and other work characteristics with psychological distress, and to estimate the contextual effects of different working environments on psychological distress, using cross-sectional data from an occupational cohort. The subjects were 3,574 non-faculty civil servants working at university campuses in Rio de Janeiro, Brazil (Pró-Saúde Study). Psychological distress was measured by the 12-item General Health Questionnaire. Work characteristics were measured by the modified version of the Karasek model and through questions about night shift work and occupational status. After adjusting for age, education, income and other work characteristics, low social support at work and high job strain were associated with psychological distress. For low social support, the association was stronger in men (Prevalence Ratio = 2.02; 95% Confidence Interval 1.6-2.6) than in women (PR = 1.46; 95% CI 1.2-1.4). High job strain was similarly significant in both women (PR = 1.43; 95% CI 1.2-1.7) and men (PR = 1.30; 95% CI 1.0-1.7). Men having a routine non-manual work presented 29% more psychological distress than those undertaking professional roles. Night shift work did not show significant association with psychological distress. In the multilevel analysis, the prevalence of psychological distress did not vary significantly across work units. Job strain and poor support at work seem important psychological stressors in the workplace in Brazil. Our findings are comparable to those found in more developed countries, providing additional evidence of an association between an adverse psychosocial work environment and psychological distress, being thus useful for policymakers in planning and promoting

    Vehicular emissions in megacities such as Sao Paulo and Rio de Janeiro are increasingly becoming a global issue. The São Paulo Metropolitan Area (SPMA), located in Southeast of Brazil, is a megacity with a population of 18 million people, with 7 million cars and large-scale industrial emissions. Rio de Janeiro is also a large city with different meteorology than São Paulo. All cars in Brazil runs gasohol, with 23% ethanol in gasoline, and for the last 10 years, flex cars that can run on gasohol, ethanol or any mixture dominate the market. Overall ethanol accounts for about 30-40% of fuel burned in both cities. To improve the understanding of vehicular emission impacts on aerosol composition and life cycle in these two large megacities a source apportionment study, combining online and offline measurements, was performed. Aerosols were collected for one year to capture seasonal variability at 4 sites in each city, with inorganic and organic aerosol component being sampled. Organic and elemental carbon were measured using a Sunset Laboratory Dual Optics (transmission and reflectance) Carbon Analyzer and about 22 trace elements has been measured using polarized X-Ray Fluorescence (XRF). Aerosol mass and black carbon were also measured, as well as trace gases to help in aerosol source apportionment. In Sao Paulo, the average PM2.5 mass concentration obtained varied from 9.6 to 12.2 μg m-3 for the several sites, and similar concentrations were measured in Rio de Janeiro. At all sites, organic matter (OM) has dominated fine mode aerosol concentration with 42 to 60% of the aerosol mass. EC accounted for 21 to 31% of fine mode aerosol mass concentration. Sulfate accounted for 21 to 26% of PM2.5 for the sites. Aerosol source apportionment was done with receptor analysis and integration with online data such as PTR-MS, Aethalometers, Nephelometers and ACSM helped to apportion vehicular emissions. For the 8 sites operated in Sao Paulo and Rio de Janeiro, vehicular

    Full Text Available The paper is a contribution for the knowledge upon concentrations and fate of different kinds of organic micropollutants in Tropical River system from a very industrialized region in Brazil. The presented data was obtained during three years of an International Research Project between Brazilian and Dutch institutions. The sediments were sampled at the Paraiba do Sul-Guandu river watershed, the most important watercourse of Rio de Janeiro state, where up 90 % of the population depends on its water for domestic uses. After extraction with non-polar solvents in a hot sohxlet device and clean up using chromatographic columns, three classes of organic micropollutants were analyzed: organochlorine insecticides (OCs, polychlorinated biphenyls (PCBs and polynuclear aromatic hydrocarbons (PAHs. The organochlorines, including the PCBs were scarcely present in the collected samples probably reflecting the restrictions of use of this class of compounds in the Brazilian market. However, the PAHs levels were high at the vicinity of a huge steelworks located in the city of Volta Redonda. This contamination is probably due to the massive use of coal in the above-cited metallurgical plant.Este artigo pretende contribuir para o conhecimento sobre a concentração e destino de diferentes tipos de micro-poluentes num sistema fluvial tropical de uma região brasileira altamente industrializada.

    Full Text Available Spatial patterns of shallow landslide initiation reflect both spatial patterns of heavy rainfall and areas susceptible to mass movements. We determine the areas most susceptible to shallow landslide occurrence through the calculation of critical soil cohesion and spatial patterns of rainfall derived from TRMM (Tropical Rainfall Measuring Mission data for Paraty County, State of Rio de Janeiro, Brazil. Our methodology involved: (a creating the digital elevation model (DEM and deriving attributes such as slope and contributing area; (b incorporating spatial patterns of rainfall derived from TRMM into the shallow slope stability model SHALSTAB; and (c quantitative assessment of the correspondence of mapped landslide scars to areas predicted to be most prone to shallow landsliding. We found that around 70% of the landslide scars occurred in less than 10% of the study area identified as potentially unstable. The greatest concentration of landslides occurred in areas where the root strength of vegetation is an important contribution to slope stability in regions of orographically-enhanced rainfall on the coastal topographic flank. This approach helps quantify landslide hazards in areas with similar geomorphological characteristics, but different spatial patterns of rainfall.

    This paper presents the results obtained in a program for the postal evaluation of radiation protection parameters in dental radiography in the state of Rio de Janeiro. The postal kit contains a radiographic film and two pairs of thermoluminescent dosimeters separated by a 3 mm aluminium filter and is accompanied by a questionnaire about equipment characteristics and exposition parameters. The analysis of 2596 equipment in the last three years showed that near half of the examinations produces doses higher than the diagnostic reference level established by the health authorities for this kind of examination. Field diameter is within the acceptable range in 73,5% of the tests and total filtration is higher than 1,5 mm Al equivalent in 86,64% of the cases. Comparing with earlier results this analysis suggests that radiation protection conditions in dental radiography are improving in the state of Rio de Janeiro. (author)

    Full Text Available Experimental releases of female Aedes (Stegomyia aegypti and Aedes (Stegomyia albopictus were performed in August and September 1999, in an urban area of Nova Iguaçu, State of Rio de Janeiro, Brazil, to estimate their flight range in a circular area of 1,600 m where 1,472 ovitraps were set. Releases of 3,055 Ae. aegypti and 2,225 Ae. albopictus females, fed with rubidium (Rb-marked blood and surgically prevented from subsequent blood-feeding, were separated by 11 days. Rb was detected in ovitrap-collected eggs by atomic emission spectrophotometry. Rb-marked eggs of both species were detected up to 800 m from the release point. Eggs of Ae. albopictus were more numerous and more heterogeneously distributed in the area than those of Ae. aegypti. Eggs positively marked for Rb were found at all borders of the study area, suggesting that egg laying also occurred beyond these limits. Results from this study suggest that females can fly at least 800 m in 6 days and, if infected, potentially spread virus rapidly.

    Organochlorinated compounds, seven indicator PCB congeners, DDT and its main metabolites, were determined in sediment and crab (Chasmagnathus granulata) samples collected from mangrove areas near Rio de Janeiro, Brazil. Samples were analysed according to the FAO/SIDA protocols using continuous non-polar solvent extraction and a conventional GC-ECD apparatus. The highest levels of total PCB congeners and total DDT metabolites in sediments (184.16 and 37.40 ng.g−1d.w. respectively) and crab eggs (570.62 and 98.22 ng.g−1d.w. respectively) were found at impacted mangroves. The higher PCB congeners than DDT metabolites levels suggesting a stronger industrial impact in this area. The results indicate that the population density of crab is negatively affected by sediment contamination that is reflected basically by the organochlorine content in the female eggs. The organochlorine concentration in eggs is more significant to evaluate or estimate an impact of these pollutants upon C. granulata population than the organochlorine concentration in sediment samples.

    Full Text Available OBJECTIVE: To assess incidence and predictors of first pregnancy among women with HIV/AIDS. METHODS: Prospective cohort study was conducted in Rio de Janeiro, southeastern Brazil, between 1996 and 2003. This study comprised 225 women with HIV/AIDS followed up until their first pregnancy or first censored event (hysterectomy, tubal ligation, menopause, 50 years of age, loss to follow-up, death or the end of December 2003. Pregnancy and abortion rates were estimated, and Cox proportional hazards models were used to identify baseline characteristics associated with pregnancy risk. RESULTS: The women were followed up for 565 person/years with a median follow-up of 3 years per women. The mean age was 32 years (SD: 7, and 54.7% were white. There were 60 pregnancies in 39 women, and 18 were terminated (induced abortions, accounting for a rate of 6.9% and 2.1% women/year, respectively. Repeated pregnancies occurred in 33.3% of the women (13/39. Higher pregnancy risk was seen among younger women (HR=3.42; 95%CI: 1.69;6.95 and those living with their partners (HR=1.89; 95%CI: 1.00;3.57. Lower pregnancy risk was associated with higher education level (HR=0.43; 95%CI: 0.19;0.99 and use of antiretroviral therapy (HR=061; 95%CI: 0.31;1.17. CONCLUSIONS: Lower pregnancy rates were found in our cohort than in the general population. Sociodemographic characteristics should be taken into consideration in the management of reproductive health in HIV-positive childbearing age women. Reproductive and family planning counseling must be incorporated into HIV/AIDS programs for women to help preventing HIV transmission to their partners and offspring.

  17. Practices and ethical concerns regarding preimplantation diagnosis. Who regulates preimplantation genetic diagnosis in Brazil?

    Directory of Open Access Journals (Sweden)

    B.B. Damian

    2015-01-01

    Full Text Available Preimplantation genetic diagnosis (PGD was originally developed to diagnose embryo-related genetic abnormalities for couples who present a high risk of a specific inherited disorder. Because this technology involves embryo selection, the medical, bioethical, and legal implications of the technique have been debated, particularly when it is used to select features that are not related to serious diseases. Although several initiatives have attempted to achieve regulatory harmonization, the diversity of healthcare services available and the presence of cultural differences have hampered attempts to achieve this goal. Thus, in different countries, the provision of PGD and regulatory frameworks reflect the perceptions of scientific groups, legislators, and society regarding this technology. In Brazil, several texts have been analyzed by the National Congress to regulate the use of assisted reproduction technologies. Legislative debates, however, are not conclusive, and limited information has been published on how PGD is specifically regulated. The country requires the development of new regulatory standards to ensure adequate access to this technology and to guarantee its safe practice. This study examined official documents published on PGD regulation in Brazil and demonstrated how little direct oversight of PGD currently exists. It provides relevant information to encourage reflection on a particular regulation model in a Brazilian context, and should serve as part of the basis to enable further reform of the clinical practice of PGD in the country.

    The Instituto de Radioprotecao e Dosimetria, IRD/CNEN, started in 1980 a program called 'PATIENT EXPOSURES IN ORAL RADIOLOGY'. The basic goal is the reduction of patient exposure during dental X-ray examinations. The program is being applied by mail to the pilot area of the city of Rio de Janeiro and covers the following topics: 1. Determination of skin doses and all physical parameters inherent to radiographic examinations wich are needed for effective dose equivalent calculations; 2. Guidance to dentists regarding proper techniques, basic procedures in Radiation Protection and aptimization of the radiographic image. According to the results obtained from 308 people studied the exposure ranged from 200mR to 4000mR at the patient skin during a molar X-ray. In regard to field diameter measurements in this group it was observed that 40% of the X-ray units used showed higher values than the acceptable limit of 7.5cm at skin. (Author) [pt

    The UN Conference on Environment and Development held in June 1992 in Brazil has been the biggest environment conference ever, but whether this Earth Summit can claim to be a big event in terms of results achieved is a matter of controversial debates all around the world. Judging the conference's success against the background of the global environmental situation, the decisions taken in Rio de Janeiro seem to fall short of current needs. However, even critics admit that this conference has initiated a process which is likely to exert a decisive impetus on global politics over the decades to come. The book in hand presents the major results and decisions of the conference and excerpts of important reports and speeches from various countries, and gives an outline of the resulting consequences and perspectives of the emergin 'process after Rio'. The concluding part of the book is a documentation presenting the UN Global Climate Convention, the Biodiversity Convention, the Declaration of Rio de Janeiro, the Forest Declaration, and excerpts of Agenda 21.

    Time series of pollutants and weather variables measured at four sites in the city of Rio de Janeiro, Brazil, between 2002 and 2004, were used to characterize temporal and spatial relationships of air pollution. Concentrations of particulate matter (PM10), sulfur dioxide (SO2) and carbon monoxide (CO) were compared to national and international standards. The annual median concentration of PM10 was higher than the standard set by the World Health Organization (WHO) on all sites and the 24 h means exceeded the standards on several occasions on two sites. SO2 and CO did not exceed the limits, but the daily maximum of CO in one of the stations was 27% higher on weekends compared to weekdays, due to increased activity in a nearby Convention Center. Air temperature and vapor pressure deficit have both presented the highest correlations with pollutant's concentrations. The concentrations of SO2 and CO were not correlated between sites, suggesting that local sources are more important to those pollutants compared to PM10. The time series of pollutants and air temperature were decomposed in time and frequency by wavelet analysis. The results revealed that the common variability of air temperature and PM10 is dominated by temporal scales of 1-8 days, time scales that are associated with the passage of weather events, such as cold fronts.

    Full Text Available ABSTRACT Objectives To better understand the role that health care plays in breast cancer survival by investigating the effects that hormone therapy adherence and other select health care variables, adjusted for clinical and sociodemographic factors, had among a population of women in Rio de Janeiro, Brazil. Methods This was a longitudinal study based on secondary data of 5 861 women treated with hormone therapy (tamoxifen or aromatase inhibitors at the National Cancer Institute of Brazil (INCA, from 1 January 2004 – 29 October 2010. Four different sources of data were integrated for analysis: INCA Pharmacy Sector Dispensation System; Hospital-based Cancer Registry; Integrated Hospital System and INCA Absolute System; and Mortality Information System. Analyses explored the effects of adherence to hormone therapy, disease care aspects, and sociodemographic, behavioral, and clinical variables, on the time of survival, using Kaplan-Meier and Cox proportional hazards models. Results The general survival rate was 94% in the first year after initiation of hormone therapy, and 71% in the fifth year. The Cox model indicated a higher hazard of death among women smokers, with more hospitalizations, more exams, and, among those who used, who used only aromatase inhibitors, as hormone therapy modality. The hazard was lower among women with a partner (stable relationship, a high school or college education a family history of cancer, and those who were treated by a mastologist, oncologist, and/or psychotherapist, who underwent surgery, and who adhered to hormone therapy. Conclusions The study indicated more vulnerable sub-groups and the aspects of care that provide best results, bringing new knowledge to improve assistance to this group of women.

    Full Text Available Abstract: This article presents results for young men’s health based on an intervention-study on gender, sexuality, and health of adolescents and young men in conflict with the law, deprived of their freedom, and subject to socio-educational confinement in Rio de Janeiro, Brazil. The themes addressed included questions on overall health, mental health, and sexual and reproductive health, analyzed from a relational gender perspective and social construction of masculinities. The majority of these young men are black, from low-income communities, with low schooling levels, and ranging in age from 14 to 21 years of age; some of them are fathers. The study showed that these young men have been exposed to police and social violence from a very early age and have been deprived of their freedom due to involvement with the drug traffic, homicides, or episodes of sexual violence. The male and female health professionals that work with them report that the most common health problems are skin conditions, mental disorders, and sexually transmissible infections. Male chauvinism and rigid notions of gender and sexuality are important factors in the views of these young men on health (especially sexual and reproductive.

    As there are few studies about evaluation of attitudes of health care workers to people with mental disorders in Brazil, a cross-sectional study was carried out to assess the health professionals' attitudes working in a university hospital in Rio de Janeiro and also examine the proportion of negative and positive attitudes endorsed by healthcare professionals in Brazil towards people with mental illness in comparison with other parts of the world. Data were collected using the Community Attitudes towards the Mentally Ill (CAMI) in a random sampling frame of health professionals (n = 246) working in a University Hospital in Rio de Janeiro between April 2013 and June 2013. The CAMI consists of four sub-scales: Authoritarianism, Benevolence, Social Restrictiveness and Community Mental Health Ideology. The results showed attitudes that range from neutral to positive, with the Benevolence and Social Restrictiveness sub-scales showing the least stigmatizing results. The following individual characteristics were associated with negative attitudes: lower levels of education and less clinical experience. In general, health workers attitudes towards service users are characterized as positive when compared with other international studies. However, educational programs for health workers should be reinforced to further promote pre-existing positive attitudes towards people with mental health and the implementation of Brazilian Mental Health Policies.

    The repeating of the experiments of Wilhelm Konrad Roentgen in Brazil happened thanks to the initiative of physician' from Rio de Janeiro and Minas Gerais. The present article, research fruit and documental rising from the archive of the Center of Memory of the Medicine (UFMG), it verified how the scientific innovations reached the Brazilian medical society. One year after X-ray's discovery (1895), Dr. Francisco Pereira das Neves got to repeat the German scientist's experiments. Based on imported material, as tube of Crookes, tube Hittorf, Ruhmkorff's inductor and plate Lumiere, the first X-ray for clinical medicine started in September of 1896. In Minas Gerais, the pioneer was Dr. Jose Carlos Ferreira Pires that, in 1898, brought the X-ray's took to the city of Formiga, being the first X-ray's device of South America. The distance of the great world scientific centers and the inherent difficulties the obtaining technical publications and foreigner supplies were not barriers. Everything was still for being understanding: the time of exposition, the correct way of the reading the foils, X rays effects in human. Until the decade of 1960 x-ray's use was predominantly for diagnosis ends, as they attest Brazilian medical publications. Therapeutic aspects of the radiation have been addressed as a focus in Brazil only after 1963. The present article intends to discuss the paper in the introduction of new radiation technologies and to punctuate the qualitative jumps heading for therapeutic use of the radioactivity in Brazil, aiming external influences, pioneering and improvisations.

    Full Text Available This paper is supported by analysis and reflections on a concept of differentiated and essentially relational tourism which takes into account the complexity, diversity and contingencies associated with the local dynamics in the area of the Morro da Conceição, in the city of Rio de Janeiro, Brazil. The theoretical approach was based on the proposals of two authors: Symbolic Site of Belonging and Located Tourism of Hassan Zaoual and Geographic Area of Milton Santos. The empirical approach was developed in the light of the experiences of the Project Palacios do Rio, through participatory observations, interviews and secondary sources review. Elements and dynamics of Morro da Conceição were presented highlighting the historical context, heritage and daily life of residents and visitors of the site, and also conditions that enable the site for embracing Located Tourism. In conclusion we emphasize the importance of addressing human and social relations in tourism. Also, that the current dominant tourism industry, supported by superficial exchange and discrepant profit needs to give way to a kind of tourism that strengthens human and social values such as authenticity, solidarity, trust, empathy, curiosity and time for human relationship.

    Several medicinal plants are traditionally traded in open-air markets in Rio de Janeiro State (Brazil) to treat tuberculosis (TB) and related symptoms. Conduct a survey in the open-air markets of 20 cities of Rio de Janeiro State to find medicinal plants that are popularly used to treat tuberculosis and other related diseases and assess their in vitro antimycobacterial activity. We used direct observation and semi-structured interviews and asked herbalists to list species (free listing) in order to gather data about the plant species most commonly used for lung problems. We calculated a Salience Index and acquired two species of "erva-de-passarinho" (mistletoe), Struthanthus marginatus and Struthanthus concinnus (Loranthaceae), commonly used to treat tuberculosis for a bioassay-guided isolation of the antimycobacterial active principles. Extracts, fractions and isolated compounds of both species were assayed in vitro against susceptible (H37Rv) and rifampicin-resistant (ATCC 35338) Mycobacterium tuberculosis strains. From the interviews, we generated a list of 36 plant species belonging to 12 families. The mistletoes Struthanthus marginatus and Struthanthus concinnus showed high Salience Index values among plants used to treat tuberculosis. Bioassay-guided fractionation of hexane extracts from both species led to the isolation and/or identification of steroids and terpenoids. The Minimum Inhibitory Concentration (MIC) of the extracts and isolated compounds ranged from 25 to 200 μg/mL. Some of the isolated compounds have been previously assayed against Mycobacterium tuberculosis, others are reported here for the first time (obtusifoliol: MIC H37Rv 50 μg/mL, MIC ATCC 35338 12.5 μg/mL; 3-O-n-acil-lup-20(29)-en-3β,7β,15α-triol: MIC H37Rv 200 μg/mL, MIC ATCC 35338 100 μg/mL). This study demonstrated the importance of ethnobotanical surveys in markets as a source for new drugs and also for scientific validation of folk medicine. © 2013 Elsevier Ireland Ltd. All

    The distribution of fallout {sup 137}Cs in soil samples of the Rio de Janeiro State was investigated. Two-hundred sixty-two samples of soil were analyzed for {sup 137}Cs by gamma spectrometry. A reference data set was built containing thirty-six detected values (14%) and two hundred twenty-six (86%) multiple detection limits of non-detected observations. Distribution pattern of the radionuclide, as well their controlling factors were evaluated based on statistical methods for censored data set (with non-detected observations). The mean of concentration values of thirty-six detected observations was 1.25 Bq.kg{sup -1}, while for the censored data sets the mean value was 0.51 Bq.kg{sup -1}. The references values for the Rio de Janeiro State were estimated as 1.44 Bq.kg{sup -1} (75{sup th}) and 1.78 Bq.kg{sup -1} (90{sup th}) (considering the year of 2015). {sup 137}Cs concentrations tend to be higher in soils with high levels of organic matter and clay and locations with high levels of these parameters would provide higher Cs fixation. No influence of the rainfall index and soil pH on the Cs content in soil was observed. The data and information gathered in this study provide valuable information for decision making purposes in case of soil contamination. (author)

    Full Text Available During six consecutive months, sampling were made at three points located on Governador Island and three on Paquetá Island in Guanabara Bay, Rio de Janeiro, Brazil. Material was collected from dock pilings and rocks in the intertidal zone. In these samples, five species belonging to three families, Corynidae, Kirchenpaueriidae and Campanulariidae, were identified. The campanulariid species Obelia dichotoma Linnaeus, 1758, dominated at nearly all points sampled. The small number of species obtained in this survey is attributed to the intense pollution in the bay, which borders the second-largest industrial complex and the second-largest demographic center of Brazil.Durante seis meses consecutivos foram feitas coletas em três pontos localizados na ilha do Governador e três em Paquetá, sendo colhido material em pilares de cais e rochas na zona entremarés. Foram identificadas cinco espécies pertencentes a três famílias: Corynidae, Kirchenpaueriidae e Campanulariidae. A espécie Obelia dichotoma Linnaeus, 1758 dominou em praticamente todos os pontos. O pequeno número de espécies encontradas neste levantamento deve-se, provavelmente, ao alto grau de poluição atualmente existente na baía, uma vez que ela abriga o segundo maior polo industrial e o segundo maior centro demográfico do Brasil.

    The bacteriological quality of crabs from three different mangroves (Itaóca, Suruí, and Piedade) from Rio de Janeiro state, Brazil, was investigated using conventional and molecular methods. The results revealed high counts for total coliforms in meat and hepatopancreas samples. PCR analyses identified 25 Escherichia coli colonies in the Itaóca, Piedade, and Suruí samples, detecting 13 enterotoxigenic colonies and 9 enteroaggregative colonies. Respectively, 12, 11, and 21 Vibrio parahaemolyticus strains were detected in the Itaóca, Piedade, and Suruí samples. Two V. cholerae strains were detected in the Piedade samples. The E. coli strains isolated in the present study showed resistance to gentamicin. E. coli strains from the Piedade samples showed 33% resistance to chloramphenicol and the strains also showed multiresistance to several antimicrobial agents with a MAR index ranging from 0.12 to 0.31. Vibrio strains from Piedade, Itaóca, and Suruí showed 86%, 78%, and 85% resistance, respectively, to ampicillin. The isolated Vibrio strains showed multiresistance to several antimicrobial agents, with a MAR index ranging from 0.12 to 0.25. The presence of these organisms in crab meat is an indication of microbial contamination, which may pose health risks to consumers when improperly cooked.

    Full Text Available We studied the ecology of ticks found in different species of a taxocenosis of snakes from the Serra do Mendanha, an area of Atlantic Rainforest located in the state of Rio de Janeiro, southeastern Brazil. Snakes were sampled monthly in the field during a period of 48 months. The specific identity of the hosts and their parasites, the number of parasites, and and snout-vent length and body mass of each host were recorded. A total of 25% of the species of snakes in the area were parasitized by ticks (larvae, nymphs and adult females Amblyomma rotundatum Koch, 1844 was the predominant parasite species. The infestation parameters varied among the species of snakes sampled, with the highest prevalence of A. rotundatum being observed in the viperid Bothrops jararaca (Wied, 1824 (71.4%, followed by the colubrids Xenodon neuwiedii Günther, 1820 (33%, Chironius laevicollis (Wied, 1824 and Spilotes pullatus (Linnaeus, 1758 (both with 22%. The latter three species also showed the highest rates of infestation by A. rotundatum. The results of the present study suggest that a combination of skin shedding, habitat of the host, type of scale and pattern of scale distribution on the body of the host can influence the degree to which a given species is parasitized by ticks

    The fast-growing formation of solid waste, resulting from demographic density, presents itself as one of the most pressing problems to be addressed by governments of large cities all over the world. In Rio de Janeiro, 60% of solid waste stems from the construction industry. Although envisaged by under current municipal legislation, no application of policy regarding systematic recycling of this kind of waste exists in fact. Both sanitation experts and epidemiologists highlight that the deficient sanitary system contributes to the growth of endemic breeding sites, which may reach epidemic proportions. In Brazil, over the recent years, there has been an increase of Dengue Fever cases followed by deaths. In the first half of 2008, the State of Rio de Janeiro was plagued by an intense Dengue epidemic. The city of Rio de Janeiro alone accounted for 48.7% of the cases, in absolute values. By drawing upon an analytical method based on the interrelation between health and sanitation, the outcomes herein indicate that the city of Rio de Janeiro bears a direct relation between Dengue incidence rates and rubble formation from construction - measured by the total area built. Thus, there is a strong urge to implement recycling systems out of construction rubble as a sanitation measure in order to promote Dengue incidence reduction.

Brazil does not have a program instituted for the monitoring of deaths of horses. By means of a descriptive study in association with a multivariate analysis method, an epidemiologic profile was determined for deaths related to musculoskeletal (MS, gastrointestinal (GI, respiratory (RES systems, neurologic origin (NEU and sudden death (SD for the years of 2002 to 2008, at the Octavio Dupont Veterinary Hospital-Rio de Janeiro (ODVH. Males comprised the majority of deaths and that deaths were related to, decreasing order, MS>GI>SD>NEU>RES, with respect to general mortality rate per large group of determined causes (TSPMr. The majority of deaths registered included horses aged four to five years (ID4-ID5. We observed the following correspondence relations: (3-year period = SM - ID>5 - SD; ID>5 - GI; ID4-5 - MS; SF - ID5 - GI; SF - ID5. The present study points out the importance and necessity of epidemiologic studies of lesions in horses, based on diagnosis for the recognition of predisposing factors and prevention.

Eighty-three randomly selected male workers participated in the present study, aimed at assessing the physiological workload of garbage collection (GC in Rio de Janeiro, Brazil. Heart rate (HR was obtained on four consecutive workdays. Energy expenditure (EE was extrapolated from heart rate data based on individual laboratory-established heart rate/oxygen consumption curve in 70 workers. Mean HR during GC was 104.0 ± 11.7bpm (± SD, representing 56.9 ± 7.5% of maximum heart rate. EE was 1608.3 ± 738.5kcal for an average of 293.1 ± 103.9 minutes of work per day. Based on all measurements, work in garbage collection in Rio de Janeiro can be considered excessively heavy. These data emphasize the need to develop appropriate classification of workload to be used in health-related research and in the development of maximum acceptable work time in association with the physiological workload, particularly in developing countries.A carga de trabalho fisiológica é utilizada para estimar a demanda física de uma tarefa na população de trabalhadores adultos; no entanto, nos países em desenvolvimento há poucos dados disponíveis sobre as diversas atividades ocupacionais.

    Full Text Available An epidemic of sporotrichosis, a subcutaneous mycosis caused by the fungus Sporothrix schenckii, is ongoing in Rio de Janeiro, Brazil, in which cases of human infection are related to exposure to cats. In an attempt to demonstrate the zoonotic character of this epidemic using molecular methodology, we characterised by DNA-based typing methods 19 human and 25 animal S. schenckii isolates from the epidemic, as well as two control strains. To analyse the isolates, the random amplified polymorphic DNA (RAPD technique was performed using three different primers, together with DNA fingerprinting using the minisatellite derived from the wild-type phage M13 core-sequence. The analyses generated amplicons with considerable polymorphism. Although isolates exhibited high levels of genetic relatedness, they could be clustered into 5-10 genotypes. The RAPD profiles of epidemic S. schenckii isolates could be distinguished from that of the United States isolate, displaying 20% similarity to each primer and 60% when amplified with the M13 primer. DNA fingerprinting of S. schenckii isolated from the nails (42.8% and the oral cavities (66% of cats were identical to related human samples, suggesting that there is a common infection source for animals and humans in this epidemic. It is clear that cats act as a vehicle for dissemination of S. schenckii.

    In the last three decades, Sepetiba bay, located about 60 km south of the city of Rio de Janeiro, Brazil, has been subjected to increasing pollution impacts. The Sepetiba region has undergone fast industrial expansion leading to high levels of pollution by metals. For the last two decades, an industrial park composed of about 400 industrial plants, basically metallurgical, was established in the Sepetiba Bay basin, releasing its effluents either straight into the bay or through local rivers. Potential toxic elements such as As, Zn, Cr, Pb and Cd have been introduced into the bay through industrial and domestic wastes. In the present paper, instrumental neutron activation analysis (INAA) was applied to determine the elements As, Cr and Zn in sediments from Sepetiba bay, sampled in August 2003, in order to compare to previous results obtained in 1998, for these elements, by Pellegatti et al. (2001). By using a geostatistical model it was possible to evaluate the spatial mobility of As, Cr and Zn in the last six years. The results obtained showed that none of the studied elements showed a significant spatial mobility. This behavior is probably related to geochemical barriers present in Sepetiba bay. (author)

    Full Text Available The context of first drug injection and its association with ongoing injecting practices and HCV (hepatitis C virus infection were investigated. Injection drug users (IDUs (N = 606 were recruited in "drug scenes" (public places, bars in Rio de Janeiro, Brazil, interviewed, and tested for HCV. Sharing of needles/syringes was more prevalent at the first injection (51.3% than at the baseline interview (36.8%. Those who shared syringes/needles at first injection were more likely to be currently engaged in direct/indirect sharing practices. Among young injectors (< 30 years, those reporting sharing of needles/ syringes at the first injection were about four times more likely to have been infected by HCV. Hepatitis C virus prevalence among active IDUs (n = 272 was 11%. Prison history and longer duration of drug injection were identified as independent predictors of HCV infection. To effectively curb HCV transmission among IDUs and minimize harms associated with risk behaviors, preventive strategies should target individuals initiating drug injection beginning with their very first injection and discourage the transition from non-injecting use to the self-injection of illicit drugs.

    A. S. Cordeiro

    Full Text Available Eighty-nine specimens of Selene setapinnis (Mitchill, 1815 collected from the coastal zone of the State of Rio de Janeiro (21-23ºS, 41-45ºW and 23º05'S, 44º30'W, Brazil, from August 2001 to May 2002, were necropsied to study their metazoan parasites. Eighty-one (91% specimens of S. setapinnis were parasitized by one or more metazoan species. Twenty-one species of parasites were collected: 8 digeneans, 3 monogeneans, 2 cestodes, 5 nematodes, and 3 copepods. The endoparasites (digeneans, cestodes, and nematodes were 74.1% of total number of parasite specimens collected. The monogenean Pseudomazocraes selene (Hargis, 1957 was the most dominant species with the highest prevalence in the parasite community of S. setapinnis. The metazoan parasites of this host species showed the typical aggregated pattern of distribution. Only one parasite species (Acanthocolpoides pauloi Travassos, Freitas & Buhrnheim, 1955 showed positive correlation between the host total length and parasite abundance in S. setapinnis. Caligus robustus Bassett-Smith, 1898, P. selene, and Terranova sp. demonstrated positive correlation between the host total length and prevalence. Larvae of Terranova sp. showed influence of the host sex on its prevalence. A pair of ectoparasite species, P. selene-C. robustus, exhibited positive covariation between their abundances. Two pairs of endoparasite species, L. microstomum-P. merus and A. pauloi-P. merus showed significant covariation among their abundances; and the pair Terranova sp.-Raphidascaris sp. had positive co-ocorrence and covariation in the infracommunities of S. setapinnis. Like the parasite communities of the other carangid fishes from Rio de Janeiro, the parasite community of S. setapinnis is apparently only a slightly ordered species complex, characterized by dominance of endoparasite species.

    As part of a research study on the 1930s and 1940s medical-criminological debate in Brazil, this research paper analyzes some of the uses and criticisms of arguments of a psychiatric and criminological nature, among certain jurists who carried out important work in the city of Rio de Janeiro during the 1930s. In this context, these magistrates, tended to have significant psychiatric and criminological knowledge, in spite of all the heterogeneity, plurality and differences in perspectives that existed among them. We selected two principal areas to conduct an analysis of the activities of these jurists: the Appellate Court of the Federal District of Rio de Janeiro and Jury Trial Courts.

    Full Text Available Leprosy is an ancient infectious disease caused by Mycobacterium leprae. According to comparative genomics studies, this disease originated in Eastern Africa or the Near East and spread with successive human migrations. The Europeans and North Africans introduced leprosy into West Africa and the Americas within the past 500 years. In Brazil, this disease arrived with the colonizers who disembarked at the first colonies, Rio de Janeiro, Salvador and Recife, at the end of the sixteenth century, after which it was spread to the other states. In 1854, the first leprosy cases were identified in State of Amazonas in the north of Brazil. The increasing number of leprosy cases and the need for treatment and disease control led to the creation of places to isolate patients, known as leprosaria. One of them, Colonia Antônio Aleixo was built in Amazonas in 1956 according to the most advanced recommendations for isolation at that time and was deactivated in 1979. The history of the Alfredo da Matta Center (AMC, which was the first leprosy dispensary created in 1955, parallels the history of leprosy in the state. Over the years, the AMC has become one of the best training centers for leprosy, general dermatology and sexually transmitted diseases in Brazil. In addition to being responsible for leprosy control programs in the state, the AMC has carried out training programs on leprosy diagnosis and treatment for health professionals in Manaus and other municipalities of the state, aiming to increase the coverage of leprosy control activities. This paper provides a historical overview of leprosy in State of Amazonas, which is an endemic state in Brazil.

    It has been reported that the formation and stabilization of coastal dune fields in Brazil have a dependence on the climate changes and Relative Sea Level (RSL) variations. A few topics regarding the morphodynamics of coastal aeolian systems in Brazil can be the RSL variations in the Holocene and weather conditions. In this work, a dune field known as 'Dama Branca', located in the town of Cabo Frio, Rio de Janeiro, has been studied to understand its formation and stabilization. Dating by trapped charge dating techniques as Optically Stimulated Luminescence (OSL) using the Single Aliquot Regenerative protocol (SAR), help to understand the formation and dynamics of aeolian systems in Brazil. Samples from a dune were collected from different heights and points for dating. The results obtained by OSL-SAR showed that ages decrease as the height from the dune base increase and older samples are found in deeper horizontal positions. The ages for the base of the studied dunes indicated that its stabilization occurred during the recess of the sea level. (author)

    Full Text Available Objective: To understand how the HIV diagnosis combines with other factors that influence the decision to abort.Methodology: Data were collected during a crossover study of women aged between 18 and 49 years old and seen in public health services in Porto Alegre, Brazil. The life stories of 18 interviewees who had post-diagnosis abortion were reconstructed on a timeline, using information collected quantitatively.Results: The time between the diagnosis and abortion was 2 years or less for more than half of the women. For some, post-diagnosis abortion did not mean the end of reproductive life. The most frequent reason for terminating pregnancy was to be living with HIV; however, only some of the women who stated having this motivation did not have post-diagnosis children. Changing partners between pregnancies was a recurring finding; however, in most pregnancies that ended in abortion, the women lived with their partners.Discussion: The analysis of the reproductive trajectory of the women studied showed that there is no specific profile of the woman who aborts after receiving the HIV diagnosis. Although this diagnosis may be involved in the decision to terminate a pregnancy, it does not necessarily result in the end of a woman's reproductive trajectory. Thus, abortion should be understood within a diversity of decision-making processes and the specific moment of a woman's life story.

    This paper presents the results obtained in a program for the postal evaluation of radiation protection parameters in dental radiography in the state of Rio de Janeiro. The postal kit contains a radiographic film and two pairs of thermoluminescent dosimeters separated by a 3 mm aluminium filter and is accompanied by a questionnaire about equipment characteristics and exposition parameters. The analysis of 2596 equipment in the last three years showed that near half of the examinations produces doses higher than the diagnostic reference level established by the health authorities for this kind of examination. Field diameter is within the acceptable range in 73,5% of the tests and total filtration is higher than 1,5 mm Al equivalent in 86,64% of the cases. Comparing with earlier results this analysis suggests that radiation protection conditions in dental radiography are improving in the state of Rio de Janeiro. (author)

    Full Text Available Introduction. Obesity is defined by the World Health Organization (WHO as a disease characterized by the excessive accumulation of body fat. Obesity is considered a public health problem, leading to serious social, psychological and physical problems. However, the appropriate cut-off point of body mass index (BMI based on body fat percentage (BF% for classifying an individual as obese in middle-aged adults living in Rio de Janeiro remains unclear. Materials and methods. This was a prospective cross-sectional study comprising of 856 adults (413 men and 443 women living in Rio de Janeiro, Brazil ranging from 30-59 years of age. The data were collected over a two year period (2010-2011, and all participants were underwent anthropometric evaluation. The gold standard was the percentage of body fat estimated by bioelectrical impedance analysis. The optimal sensitivity and specificity were attained by adjusting BMI cut-off values to predict obesity based on the WHO criteria: BF% >25% in men and >35% in women, according to the receiver operating characteristic curve (ROC analysis adjusted for age and for the whole group.Results. The BMI cut-offs for predicting BF% were 29.9 kg/m2 in men and 24.9 kg/m2 in women. Conclusions. The BMI that corresponded to a BF% previously defining obesity was similar to that of other Western populations for men but not for women. Furthermore, gender and age specific cut-off values are recommended in this population.

Whereas, E. coli ST131 is often multidrug resistant (MDR, ST69 remains susceptible to antibiotics such as cephalosporins. Both STs are commonly linked to community and nosocomial infections. E. coli phylogenetic groups B2 and D are associated with virulence and resistance profiles making them more pathogenic. Little is known about the population structure of E. coli isolates obtained from urine samples of hospitalized patients in Brazil. Therefore, we characterized E. coli isolated from urine samples of patients hospitalized at the university and three private hospitals in Rio de Janeiro, using whole genome sequencing. A high prevalence of E. coli ST131 and ST69 was found, but other lineages, namely ST73, ST648, ST405, and ST10 were also detected. Interestingly, isolates could be divided into two groups based on their antibiotic susceptibility. Isolates belonging to ST131, ST648, and ST405 showed a high resistance rate to all antibiotic classes tested, whereas isolates belonging to ST10, ST73, ST69 were in general susceptible to the antibiotics tested. Additionally, most ST69 isolates, normally resistant to aminoglycosides, were susceptible to this antibiotic in our population. The majority of ST131 isolates were ESBL-producing and belonged to serotype O25:H4 and the H30-R subclone. Previous studies showed that this subclone is often associated with more complicated UTIs, most likely due to their high resistance rate to different antibiotic classes. Sequenced isolates could be classified into five phylogenetic groups of which B2, D, and F showed higher resistance rates than groups A and B1. No significant difference for the predicted virulence genes scores was found for isolates belonging to ST131, ST648, ST405, and ST69. In contrast, the phylogenetic groups B2, D and F showed a higher

    Wild polioviruses still remain endemic in three countries (Afghanistan, Pakistan, and Nigeria) and re-emergency of wild polio has been reported in previously polio-free countries. Environmental surveillance has been used as a supplementary tool in monitoring the circulation of wild poliovirus (PVs) and/or vaccine-derived PVs even in the absence of acute flaccid paralysis cases. This study aimed to monitor the presence of polioviruses in wastewater samples collected at one wastewater treatment plant located in the municipality of Rio de Janeiro, Brazil. From December 2011 to June 2012 and from September to December 2012, 31 samples were collected and processed. RD and L20B cell cultures were able to isolate PVs and non-polio enteroviruses in 27/31 samples. Polioviruses were isolated in eight samples (type 1 Sabin = 1, type 2 Sabin = 5, and type 3 Sabin = 2). Vaccine-derived polioviruses were not detected nor evidence of recombination with other PVs or non-polio enterovirus serotypes were observed among the isolates. The Sabin-related serotypes 2 and 3 presented nucleotide substitutions in positions associated with the neurovirulent phenotype at the 5'-UTR. Changes in important Amino acid residues at VP1 were also observed in the serotypes 2 and 3. Environmental surveillance has been used successfully in monitoring the circulation of PVs and non-polio enteroviruses and it is of crucial importance in the final stages of the WHO global polio eradication initiative. Our results show the continuous circulation of Sabin-like PVs and non-polio enteroviruses in the analyzed area during the study period.

    Objective: to establish a correlation between clinical features in a group of children with tomographic diagnosis of schizencephaly and clefts extent and localization. Materials and methods: retrospective study of dossiers from the archives of Neurology and Medical Genetics Services at Instituto Fernandes Figueira/FIOCRUZ and Hospital Municipal Jesus, Rio de Janeiro, RJ, Brazil, in the period between 2000 and 2003. The study included 16 patients, nine female and seven male, with tomographic diagnosis of schizencephaly investigated for clinical findings, psychomotor development, motor/cognitive deficits and epilepsy. Results: predominance of bilateral clefts in 10:16 patients, open-lip schizencephaly type in 23:27 patients, and small lips in 11:27 patients. As regards anomalies associated with schizencephaly, pellucid septum absence was the most frequent one (10:16 patients). As regards clinical findings, 15 patients presented with developmental delay and motor deficit, six patients with cognitive deficit and ten with epilepsy. In three patients, we observed discordant clinical findings and cleft sizes, although the clefts were small, the clinical features severity was high because of other cerebral anomalies. Conclusion: the clinical features of schizencephaly are related to the size of the clefts, regardless laterality, presenting higher severity when associated with other cerebral anomalies. (author)

    The principal characteristics of the Brazil-Angola Alkaline Carbonatite Province are defined and described with specific reference to tectonic setting and economic aspects. The economic aspects of the Brazilian uranium deposits are emphasised. The Brazil-Angola Alkaline-Carbonatite Province can be divided into six Brazilian sub-provinces and two Angolan sub-provinces. Correlation between the sub-provinces of Brazil and Angola remains speculative due to the lack of detailed information, especially age determinations on the Angolan rocks. However, an analysis of the tectonic and petrochemical aspects suggests that the two Brazilian sub-provinces situated along the littoral of Rio de Janeiro/ Sao Paulo and around the periphery of the Parana Basin may be more easily comparable to the two Angolan sub-provinces than the remaining four.

    In this article, we analyze the physical and mental stress and illness of military and civil police force officers in the State of Rio de Janeiro (Brazil) due to their working conditions and professional activities. The same methodology was used for the study of two categories, namely a quantitative approach (simple random sampling by conglomerates, involving a total of 1,458 civil police officers and 1,108 military police officers, who answered questionnaires anonymously) and a qualitative approach (focal groups involving 143 professionals and 18 interviews with managers of both police forces). The data presented here are all original. Disorders identified were: overweight and obesity in both forces but mainly in the Military Police; low frequency of physical exercise and high levels of cholesterol, especially in the Civil Police. The main health complaints are neck, back or spinal cord pain, eyesight complaints and headaches/ migraines. Sixteen point two per cent of officers of both forces reported physical lesions that were more prevalent in the Military Police, among whom psychic suffering was also more frequent (SRQ20). The need for changes in the individual and professional dimensions and in institutional aspects regarding the conditions and organization of work and of health services is emphasized.

    Data on disasters around the world reveal greater seriousness in countries with lower social and economic development levels. In this context, disaster risk-reduction and resilience-building policies are priorities in the sustainable development agenda, featuring among the topics selected for the Rio+20 Summit. By means of a contribution of a conceptual nature and from examples of disasters in countries with different development levels, namely the Haiti earthquake and the torrential rains in the mountain range close to Rio de Janeiro in Brazil, the scope of this article is to demonstrate how socio-environmental vulnerability creates conditions for disasters, while at the same time limiting strategies for their prevention and mitigation. Lastly, some of the measures that disaster risk reduction and resilience-building demand in a socio-environmental vulnerability context are highlighted. These involve changes in the current patterns of social, economic and environmental development geared toward ecological sustainability and social justice as pillars of sustainable development.

    Background Leprosy is a leading cause of preventable disability worldwide. Delay in diagnosis of patients augments the transmission of infection, and allows progression of disease and more severe disability. Delays in diagnosis greater than ten years have been reported in Brazil. To reduce this delay, it is important to identify factors that hinder patients from presenting to doctors, and those that delay doctors from diagnosing patients once they have presented. This study aimed to explore factors associated with the delayed diagnosis of leprosy in Brazil. Methodology/ Principal Findings This is an exploratory study using a self-constructed questionnaire delivered to patients attending three leprosy referral clinics across three states in Brazil. Data were analysed to determine associations between variables and the time taken for participants to present to the health-service, and between variables and the time taken for doctors to diagnose participants once they had presented. Participants who suspected they had leprosy but feared community isolation were 10 times more likely to wait longer before consulting a doctor for their symptoms (OR 10.37, 95% CI 2.18–49.45, p = 0.003). Participants who thought their symptoms were not serious had a threefold greater chance of waiting longer before consulting than those who did (OR 3.114, 95% CI 1.235–7.856, p = 0.016). Forty-two point six per cent of participants reported initially receiving a diagnosis besides leprosy. These had a three times greater chance of receiving a later diagnosis of leprosy compared to those not misdiagnosed or not given a diagnosis (OR 2.867, 95% CI 1.288–6.384, p = 0.010). Conclusions/ Significance This study implies a need for patient education regarding leprosy symptoms and the reduction of stigma to encourage patients to present. The high rate of misdiagnosis reported suggests a need to increase clinician suspicion of leprosy. Further education regarding disease symptoms in medical

    Full Text Available Depression is the most prevalent psychiatric disorder during pregnancy and is associated with psychosocial and clinical obstetric factors. Despite being an important public health issue, there are few studies about this issue in Brazil. A cross-sectional study was carried out, involving 331 pregnant women attending a public primary health service over a one-year period in Rio de Janeiro city, Brazil. Participants were interviewed about their socio-demographic status, obstetric/medical conditions, life events and violence during pregnancy. Depression was assessed using the Composite International Development Interview. The prevalence of depression during pregnancy was 14.2% (95%CI: 10.7-18.5 and associated factors included: previous history of depression and any psychiatric treatment, unplanned pregnancy, serious physical illness and casual jobs. These data emphasize the need for screening for depression and its risk factors during pregnancy in settings where care is available. Psychosocial interventions and social policies need to be devised for this population.A depressão é o transtorno mental de maior prevalência durante a gravidez e está associada a fatores psicossociais e clínicos/obstétricos.

    We evaluated the profile of patients referred to the Fiocruz Outpatient Clinic, a reference center for the diagnosis and treatment of leprosy in Rio de Janeiro, RJ, and analyzed the origins and outcomes of these referrals. This is an observational retrospective study based on information collected from the Leprosy Laboratory database at Fiocruz, Rio de Janeiro, RJ, Brazil. A total of 1,845 suspected leprosy cases examined at the reference center between 2010 and 2014 were included. The originating health service referrals and diagnostic outcomes were analyzed as well as the clinical and epidemiological data of patients diagnosed with leprosy. Our data show that the profile of the patients treated at the Clinic has changed in recent years. There was an increase in both the proportion of patients with other skin diseases and those who had visited only one health service prior to our Clinic. Among the total 1,845 cases analyzed, the outcomes of 1,380 were linked to other diseases and, in 74% of these cases, a biopsy was not necessary to reach a diagnostic conclusion. A decrease in new leprosy case detection among our patients was also observed. Yet, among the leprosy patients, 40% had some degree of disability at diagnosis. The results of the present study demonstrated the importance of referral centers in support of basic health services within the decentralization strategy. But, the success of the program depends on the advent of new developmental tools to augment diagnostic accuracy for leprosy. However, it should be emphasized that for new diagnostic methods to be developed, a greater commitment on the part of the health care system regarding research is urgently needed.

    In this work, the contribution of evaporative emissions from light passenger vehicles to the degradation of the air quality was investigated on the basis of the indoor quantification of the monoaromatic volatile compounds Benzene, Toluene, Ethylbenzene and Xylenes (BTEX), specifically, a confined shopping mall parking area in the northern zone of Rio de Janeiro, a site that represents the reality of the vehicular fleet of the Metropolitan Region of Rio de Janeiro. In order to evaluate the concentration of the BTEX compounds, samples were collected, by an active sampling system using charcoal cartridge as adsorbent. The samples were extracted with organic solvent and subsequently analyzed by gas chromatography-mass spectrometry (GCMS). The average results were 54.14 μg m-3 (benzene), 209.24 μg m-3 (toluene), 45.87 μg m-3 (ethylbenzene) and 118.93 μg m-3 (xylenes). These results are compared with results from the literature of vehicular emissions in confined spaces such as garages and tunnels. Possible correlations with emissions from moving vehicles, obtained from previous studies in a tunnel of large circulation and emissions obtained in other underground parkings, are also investigated. The results suggest different emission sources.

    Full Text Available Ischnocnema (Brachycephalidae includes many species that are important members of the leaf litter frog communities in the Atlantic Rainforest of Brazil. Ischnocnema parva (Girard, 1853 is endemic to the Atlantic Rainforest biome and is restricted to the forests of southeastern Brazil. Currently, the available information about the ecology of I. parva is scarce. We studied the diet, the habitat use, reproduction and density of I. parva in an area of Atlantic Rainforest at the Concórdia mountain range, Rio de Janeiro. Individuals of I. parva were captured in April 2005 using different sampling methods: time constrained search (transects, plots of 5 x 5 m (25 m² on the litter, and pitfall traps with drift fences. We found 240 frogs; 35 females and 205 males. Females (mean SVL = 19.1 mm were significantly larger (F1,238 = 143.016, R² = 0.375, p < 0.001 than males (13.2 mm. The species preyed mainly on arthropods, with ants and isopods being the most important items, both showing high values of importance index (Ix = 50.0 and 26.7, respectively. Ischnocnema parva is a terrestrial species whose preferential microhabitat at the Serra da Concórdia was the litter of the forest floor (78.7%. The activity was predominantly crepuscular-nocturnal and the estimated density of I. parva was 24.9 ind/100 m². For the eight ovigerous females captured, the mean number of mature oocytes per female was 25 (range: 22-30 and the oocyte mean diameter was 1.11 mm (N = 40 oocytes. Oocyte number increased with female body size (R² = 0.504, F1,6 = 6.107, p < 0.05, N = 8, indicating that as females increase in size they produce larger clutches. Some ecological aspects such as diet and microhabitat use were similar to that observed for an insular population of I. parva, whereas reproductive traits differed. Thus, long term studies are necessary to understand the extent to which these differences are explained by environmental factors.

    The intense economic growth experienced by Brazil in recent decades and its consequent explosive motorization process have evidenced an undesirable impact: the increasing and unbroken trend in traffic fatality numbers. In order to contribute to road safety diagnosis on a national level, this study presents a research into two main indicators available in Brazil: mortality rate (represented by fatalities per capita) and fatality rate (represented by two sub-indicators, i.e., fatalities per vehicle and fatalities per vehicle kilometer traveled). These indicators were aggregated into a composite indicator or index through a multiple layer data envelopment analysis (DEA) composite indicator model, which looks for the optimum combination of indicators' weights for each decision-making unit, in this case 27 Brazilian states. The index score represents the road safety performance, based on which a ranking of states can be made. Since such a model has never been applied for road safety evaluation in Brazil, its parameters were calibrated based on the experience of more consolidated European Union research in ranking its member countries using DEA techniques. Secondly, cluster analysis was conducted aiming to provide more realistic performance comparisons and, finally, the sensitivity of the results was measured through a bootstrapping method application. It can be concluded that by combining fatality indicators, defining clusters and applying bootstrapping procedures a trustworthy ranking can be created, which is valuable for nationwide road safety planning.

Foram publicadas em 1852/53 nos jornais de Günther Fröbel, em Rudolstadt, com o intuito de incentivar a emigração para as fazendas de café fluminenses que haviam adotado o sistema de parceria em substituição ao sistema de trabalho escravo. Além de desempenharem a função de incentivo à emigração, construíram uma imagem do Brasil especificamente para imigrantes.This article presents nine letters of German immigrants living in coffee-plantations in the state of Rio de Janeiro. They were published in 1852/53 in Günther Fröbel's newspapers in Rudolstadt. The intention was to encourage an emigration to the fluminense coffee-plantation, which had adopted a "parceria system" instead of slavery. Besides playing a part in the promotion of the emigration they built specific images of Brazil for immigrants.

Com o objetivo de avaliar a confiabilidade e a validade da causa básica de morte "câncer de boca", no Município do Rio de Janeiro, selecionou-se no banco de dados da Secretaria Municipal de Saúde, todas as declarações de óbito (DOs com essa causa básica, no ano de 1999. As DOs foram submetidas à nova codificação da causa básica, por técnico independente, e construiu-se formulário padronizado para coleta de dados clínicos e laboratoriais para a confirmação do diagnóstico nos prontuários médicos de cada caso. Foi considerado como padrão-ouro o diagnóstico de câncer de boca formulado com base no exame histopatológico e/ou história clínica. Observou-se concordância simples de 95,1% e coeficiente kappa de 0,93. O valor preditivo positivo correspondeu a 86,5%. Conclui-se que as estatísticas de mortalidade por neoplasia de boca no Município do Rio de Janeiro são confiáveis e que é boa a validade desta causa básica, possivelmente, por se tratar de sítio de fácil acesso para a inspeção direta e com maior facilidade de confirmação clínica.Mortality statistics are frequently employed in cancer epidemiology studies. The aim of this research was to evaluate the reliability and validity of oral cavity cancer as the underlying cause of death reported on death certificates in the Municipality of Rio de Janeiro, Brazil. All death certificates since 1999 reporting this underlying cause of death were selected from the Municipal Mortality Information System. The death certificates were re-coded by an independent technician, and a standardized questionnaire was designed to collect clinical and laboratory data for diagnostic confirmation from patient records. Histopathological results and/or clinical history were considered as the gold standard to establish the diagnosis of cancer of the mouth. Reliability analysis

    Background Zika virus (ZIKV) is an emergent threat provoking a worldwide explosive outbreak. Since January 2015, 41 countries reported autochthonous cases. In Brazil, an increase in Guillain-Barré syndrome and microcephaly cases was linked to ZIKV infections. A recent report describing low experimental transmission efficiency of its main putative vector, Ae. aegypti, in conjunction with apparent sexual transmission notifications, prompted the investigation of other potential sources of viral dissemination. Urine and saliva have been previously established as useful tools in ZIKV diagnosis. Here, we described the presence and isolation of infectious ZIKV particles from saliva and urine of acute phase patients in the Rio de Janeiro state, Brazil. Methodology/Principal Findings Nine urine and five saliva samples from nine patients from Rio de Janeiro presenting rash and other typical Zika acute phase symptoms were inoculated in Vero cell culture and submitted to specific ZIKV RNA detection and quantification through, respectively, NAT-Zika, RT-PCR and RT-qPCR. Two ZIKV isolates were achieved, one from urine and one from saliva specimens. ZIKV nucleic acid was identified by all methods in four patients. Whenever both urine and saliva samples were available from the same patient, urine viral loads were higher, corroborating the general sense that it is a better source for ZIKV molecular diagnostic. In spite of this, from the two isolated strains, each from one patient, only one derived from urine, suggesting that other factors, like the acidic nature of this fluid, might interfere with virion infectivity. The complete genome of both ZIKV isolates was obtained. Phylogenetic analysis revealed similarity with strains previously isolated during the South America outbreak.

    This work is part of a program of evaluating doses in patients developed in several hospitals in the States of Rio de Janeiro and Pernambuco. We used the program DoseCal to evaluate the Input Skin Dose (DEP) and the Effective Dose (DE) in big public hospitals in the cities of Rio de Janeiro and Recife. It were included in the survey the doses of chest radiographs, cervical spine, lumbar spine, skull and pelvis in the projections AP, PA and LAT. To chest in PA the average value of DEP for the hospital A was 0.19 mGy. For to hospital B was 0.07 mGy. For the exam of the skull in PA the average value in A was 3.25 mGy and B of 0.49 mGy. With respect to radiological techniques might be noted that in most cases the hospital A used kilovoltage lower than in B and miliamperes higher. This can be one of the explanations for the difference of the values found for DEP and DE. The results showed significant discrepancies in values of doses as radiographic techniques when compared to the requirements established by the European Community for X-rays with image quality. This result is due to several factors: filtration, radiographic technique, professional technical experience and performance of radiographic equipment

    Full Text Available This study was designed to analyse the clinical and epidemiological data from human parvovirus B19 cases in a six-year study of rash diseases conduct in an urban area in Brazil (Niterói city area, State of Rio de Janeiro. A total of 673 patients with acute rash diseases were seen at two primary health care units and at a general hospital. A clotted blood sample was collected from all subjects at the time of consultation. Forty-nine per cent (330 cases of the patients were negative for dengue, rubella and measles IgM or for low avidity IgG to HHV-6. Of these 330, 105 (31.8% were identified as IgM positive to parvovirus B19 by using an antibody capture EIA. During the study period, three distinct peaks of parvovirus infection were detected, suggesting that the disease appears to cycle in approximately 4-5 years. B19 infection was characterized by variable combinations of fever, flu-like symptoms, arthropathy, and gastrointestinal symptoms. Frequency of fever and arthropathy was substantially higher in adults, 75% [chi2 (1 D.F. = 11.39, p = 0.0007] and 62.5% [chi2 (1 D.F. = 29.89, p = 0.0000], respectively. "Slapped-cheek" appearance and reticular or lace-like rash were seen in only 30.1% of the children. No adult presented this typical rash. The lack of the typical rash pattern in a large proportion of parvovirus B19 and the similarity of clinical manifestations to other rash diseases, specially to rubella, highlight the difficulty of diagnosing B19 infection on clinical grounds alone.

    The mullet Mugil liza is distributed along the Atlantic coast of South America, from Argentina to Venezuela, and it is heavily exploited in Brazil. We assessed patterns of distribution of neutral nuclear genetic variation in 250 samples from the Brazilian states of Rio de Janeiro, São Paulo, Santa Catarina and Rio Grande do Sul (latitudinal range of 23-31°S) and from Buenos Aires Province in Argentina (36°S). Nine microsatellite loci revealed 131 total alleles, 3-23 alleles per locus, He: 0.69 and Ho: 0.67. Significant genetic differentiation was observed between Rio de Janeiro samples (23°S) and those from all other locations, as indicated by FST, hierarchical analyses of genetic structure, Bayesian cluster analyses and assignment tests. The presence of two different demographic clusters better explains the allelic diversity observed in mullets from the southernmost portion of the Atlantic coast of Brazil and from Argentina. This may be taken into account when designing fisheries management plans involving Brazilian, Uruguayan and Argentinean M. liza populations.

    Full Text Available The goal of this study was to evaluate the morphometric variation of laelapine populations (Acari, Mesostigmata associated with neotropical oryzomyine rodents at different geographic localities in Brazil. Three nominal mite species were selected for study, all infesting the pelage of small mammals at different localities in Rio de Janeiro, Espírito Santo, Bahia, and the Federal District, Brazil. To analyse morphometric characteristics, thirty-seven morphological characters distributed across the whole body of each specimen were measured. We use the Analysis of Principal Components, extracting the three first axes and projecting each mite in these axes. Major species level changes in the taxonomy of the host mammals allows an independent examination of morphometric variation of mites infesting a set of distinctly different host species at different geographic localities. Gigantolaelaps vitzthumi and Laelaps differens are associated with oryzomyine rodents of the genus Cerradomys, and consistently showed a tendency to cluster by host phylogeny. Laelaps manguinhosi associated with Nectomys rattus in central Brazil is morphometrically distinct from mites infesting N. squamipes in the coastal restingas of Rio de Janeiro and Espírito Santo. The results obtained here indicate that laelapine mite populations can vary among geographic areas and among phylogenetically related host species. Clearly, the study of these mites at the population level can be an important tool for clarifying the taxonomy of both mites and hosts.

    Full Text Available Despite the prevalence of syphilis worldwide, little is known about its manifestations when associated with other Sexually Transmitted Infections (STI, specifically the Human Papilloma Virus (HPV. Current epidemiological studies show that there is a high incidence of both diseases in ambulatory clinics all over Brazil. This study aims to estimate the incidence of syphilis - HPV co-infections, among patients from the STI ambulatory clinic at the Santa Casa da Misericórdia Hospital, Rio de Janeiro, Brazil. Two-hundred and seven patients were seen in the clinic between March and December 2005, of which 113 (54.6% sought care for an HPV infection. Blood samples were taken from all patients to check syphilis serology using the flocculation and the non-treponemic test or VDRL (Venereal Disease Research Laboratory and the TPHA (Treponema Pallidum Hemagglutination Assay treponemic and confirmatory method. Of the 207 patients, 113 (54.6% consulted referring to HPV as their primary complaint, and of these, 18 (15.9% also presented with positive syphilis serology, demonstrating a high incidence of coinfection. The average age of the patients varied between 20 and 25 years, 203 (98.1% were male and 4 (1.9% were female. The predominance of the male sex in this sample confirms the profile usually treated in STI clinics across the country, and the age range is that of typically high sexually activity. Conclusion: The results demonstrated the need for a differentiated examination of all STD patients.

  4. Retrofitting Housing with Lightweight Green Roof Technology in Sydney, Australia, and Rio de Janeiro, Brazil

    Full Text Available The built environment contributes around half of total greenhouse gas emissions and with 87% of residential buildings that we will have by 2050 already built, it is vital to adopt sustainable retrofitting practices. The question is: what are the viable solutions? One answer may be green roof retrofitting. The environmental benefits include reduced operational carbon emissions, reduced urban heat island effect, increased bio-diversity, housing temperature attenuation and reduced stormwater run-off. The economic benefits are the reduced maintenance costs and lower running costs. The social gain is the creation of spaces where people have access to green areas. However, the barriers to retrofitting include the perceptions of structural adequacy, the risk of water damage, high installation and maintenance costs, as well as access and security issues. Many Australian and Brazilian residential buildings have metal sheet roofs, a lightweight material with poor thermal performance. During the summer, temperatures in Sydney and Rio de Janeiro reach 45 degrees Celsius, and in both cities, rainfall patterns are changing, with more intense downpours. Furthermore, many residential buildings are leased, and currently, tenants are restricted by the modifications that they can perform to reduce running costs and carbon emissions. This research reports on an experiment on two small-scale metal roofs in Sydney and Rio de Janeiro to assess the thermal performance of portable small-scale modules. The findings are that considerable variation in temperature was found in both countries, indicating that green roof retrofitting could lower the cooling energy demand considerably.

    Air pollutants have been associated with the exacerbation of respiratory diseases. They may intensify the inflammatory allergic response and airways reactivity to inhaled allergens. However, it is still not clear if air pollution contributes to the increased prevalence of asthma. To investigate if different levels of air pollution exposure can be related to differences in the prevalence of asthma. The International Study of Asthma and Allergies in Childhood (ISAAC) protocol was used to determine and compare the prevalence of asthma among schoolchildren in 2 cities of the metropolitan region of Rio de Janeiro, Brazil, Duque de Caxias (DC) and Seropédica (SR), which have different levels of atmospheric pollution. The research involved 4,064 students aged 13 to 14 years from 49 schools in DC and 1,129 from 17 schools in SR. Air pollution was evaluated by the concentration of inhalable particulate matter (PM10). ISAAC's written questionnaire was answered by 4,040 students aged 13 to 14 years in DC and 1,080 in SR. Between 1998 and 2000, the PM10 annual arithmetic mean was 124 microg/m3 in DC and 35 microg/m3 in SR (acceptable level is up to 50 microg/m3). The prevalence of wheezing ever was 35.1% in DC and 29.9% in SR (P = .001), and the prevalence of wheezing in the last 12 months was 19.0% in DC and 15.0% in SR (P = .002). In DC, 14.5% of the adolescents presented 1 to 3 crises of wheezing in the last year, whereas in SR only 11.0% presented 1 to 3 crises (P = .003). In this study, the prevalence of asthma in adolescents was directly related to atmospheric pollution.

    Full Text Available Tourism is perceived as an economic, social and cultural phenomenon with important social and environmental impacts. In Brazil, the Rio de Janeiro is a city that receives the most foreign tourists. However its beaches face problems because of pollution. In this context, analysis of the socio environmental awareness of tourists and hotel managers on the quality of Rio's beaches constitutes a factor in the reflection of environmental impacts and, above all, for public policies aimed at tourism. Thus, the objective of this research was to analyze the environmental awareness of tourists and managers of hotels on the impacts of pollution on the beaches of Rio de Janeiro tourism. To do this, they applied semi-structured questionnaires for tourists and managers of hotels. The results showed that tourists arriving in the city are more concerned with enjoying the beauties and the sights than to learn about the environmental conditions of Rio de Janeiro. It could be observed also that the beaches strongly influence the image they have of the city. For this reason, although most of them realize the pollution of beaches, both for aesthetics, as the public health, does not compromise the interest in visiting the Rio de Janeiro nor in attending the beaches for swimming. It is noteworthy that even in hotels that develop strategies that help educate guests, they continue with just tourists perception and do not seek to find out about potential health risks.

    Based upon several years of experience in investigations with macrozoobenthos in rivers in the states of Minas Gerais and Rio de Janeiro, a biological assessment system has been developed to indicate pollution levels caused by easily degradable organic substances from sewers. The biotic index presented here is aimed at determining water's saprobic levels and was, therefore, named the "Saprobic Index for Brazilian Rivers in Minas Gerais and Rio de Janeiro states" (ISMR). For this purpose, saprobic valences and weights have been established for 122 taxa of tropical macrozoobenthos. Investigations were carried out in little, medium sized and big rivers in mountains and plains. Through ISMR, a classification of water quality and the respective cartographic representation can be obtained. Data collection and treatment methods, as well as the limitations of the biotic index, are thoroughly described. ISMR can also be used as an element to establish complex multimetric indexes intended for an ecological integrity assessment, where it is essential to indicate organic pollution.

O artigo sustenta que o racismo desempenha importante papel no processo e que, talvez devido à representação corrente de que o Brasil é uma democracia racial, os agentes públicos podem discriminar pessoas negras sem sequer suspeitarem de que o fazem. A análise é baseada nas diferentes visões do problema como percebido por pessoas da "classe média", de um lado, e por pessoas "pobres" de outro, e também em casos concretos de racismo levados ao sistema penal. No que tange às estratégias de intervenção policial, parece claro que em razão da hierarquização social característica de nossa sociedade, qualquer ação há que ir além do círculo vicioso das medidas organizativas como se costuma acreditar seja a solução, e corresponder a necessidades de natureza diversa.

    Full Text Available This paper proposes to discuss the transformation of urban landscapes in the Paraíba River Valley as members of the coffee elite emerged in this area and a specific landscape configuration was projected there based on the use of imperial palms ( Roystonea oleracea. Chronologically speaking, the paper covers a period from 1808 to 1911; with regard to space, it focuses on the stretch between Rio de Janeiro and São Paulo, with a closer look at the case of the city of Lorena (SP, so as to encompass all the changes that took place in this region from the introduction to the decline of coffee growing as an economic activity. The urban changes during this period were accompanied by the advent and consolidation of landscapes typical of the society of coffee growers: streets lined with palm trees, a token of their close connections with the royal court, a display of their adherence to “Frenchified customs”. Such configurations were used to characterize public areas and raise them to the same status as the new buildings that gradually replaced those built in colonial style. The paper is structured around three key moments, namely: the introduction of imperial palms in Rio de Janeiro and their association with the idea of nobility and rank, and consequently with neoclassical architecture, which was brought to the colony by the 1816 French Mission; the dissemination of the use of imperial palms as a landscaping resource typical of public spaces from the royal court to the capital of São Paulo, particularly by the coffee barons during the second period of monarchic rule; and, finally, the hypothesis that the use of imperial palms to embellish public areas in São Paulo may have been introduced by a Lorena citizen associated with the coffee elite, albeit later, when Brazil was already a republic

    Full Text Available In Brazil relatively little attention is being paid to the study of the features of the spread of the AIDS epidemic towards small cities and rural areas. We report a descriptive study on the epidemiological features of HIV infection among 208 adult patients seen between July 1999 and May 2006 in the municipal HIV/AIDS Programs of three cities of inner Rio de Janeiro State: Saquarema, Santo Antonio de Pádua and Miracema. A portrait of a heterosexual epidemic emerged, with an overall male to female ratio of 1.1. More than 90% were residents of the studied cities, demonstrating a local demand for HIV-related assistance and the importance of municipal HIV/AIDS Programs. Past or current use of snorted cocaine was reported by a quarter of the patients. Older age and male gender were independent predictors of having a diagnosis of AIDS at presentation. The latter is in accordance with a more recent wave of epidemic spread towards female gender. A low frequency of male circumcision, an important determinant of heterosexual HIV transmission, was recorded. Almost 60% of the patients first presented in advanced stages of HIV infection, suggesting the existence of a large pool of undiagnosed cases in the community.No Brasil, relativamente pouca atenção vem sendo dispensada ao estudo das características do avanço da epidemia de Aids em direção aos pequenos municípios e áreas rurais.

    Full Text Available Pythiosis is caused by Pythium insidiosum and the occurrence of disease in horses was described in the North and Northwest State of Rio de Janeiro, Brazil. The disease was described in cattle, sheep, humans, and horses in different states and regions across the country. This paper describes the development of IgY and IgG polyclonal antibodies, in chicken and rabbits, respectively against proteins extracted from kunkers and hyphae of P. insidiosum from affected horses. The proteins were recognized by chicken, rabbit and horse antibodies by immunodiffusion and Western blot against majority bands of 27 and 43 KDa, and titrated by ELISA. The antibodies IgY developed by the first time against Brazilian strains of P. insidiosum may represent a valuable tool in the detection of antigens of the pathogen and contribute to further studies aimed at immunotherapy and knowledge about this disease in endemic areas in Rio de Janeiro and in Brazil.Pitiose é causada por Pythium insidiosum e a doença foi descrita em equinos no Norte e Noroeste do Estado do Rio de Janeiro, Brasil. A doença foi descrita em bovinos, ovelhas, humanos e cavalos em diferentes estados e regiões do país. Este trabalho descreve o desenvolvimento de anticorpos policlonais, IgY e IgG, em galinha e coelho, respectivamente, contra proteínas extraídas de kunkers e hifas de P. insidiosum de cavalos doentes. As proteínas foram reconhecidas por anticorpos de galinha, coelho e cavalos contra as bandas majoritárias de 27 e 34 KDa em imunodifusão e Western blot tituladas por ELISA. Os anticorpos IgY desenvolvidos pela primeira vez contra cepas brasileiras de P. insidiosum podem representar um valioso instrumento na detecção de antígenos de patógenos e contribuem para novos estudos baseados na imunoterapia e no entendimento sobre esta doença em áreas endêmicas no Rio de Janeiro e em todo o país.

  15. Noise in large cities in Brazil

    2004-05-01

    Large cities' noise is considered by the World Health Organization to be the third most hazardous pollution, preceded by air and water pollution. In urban centers, in general, and especially in developing countries such as Brazil, large populations are affected by excessive noise due mainly to traffic flow. The Brazilian Federal Government specifies noise limits, but each state can enforce its own set of noise limits, providing they are lower. The rapid economic growth, together with large migration of northern Brazilians to the developing southern urban areas in search of more lucrative jobs in construction and industrial sectors, resulted in a fast increase in activities such as vehicle and bus traffic, home construction, and development of all necessary infrastructures to support this growth. Urban noise in Brazil has been receiving the attention of national authorities only since 1990, when the Federal Government approved the first ``Program of Community Silence,'' based on ISO R 1996-1971. This paper highlights the noise situation in the five largest and most populated cities in Brazil: Sao Paulo, Rio de Janeiro, Belo Horizonte, Porto Alegre and Curitiba [Zannin et al., Appl. Acoust. 63, 351-358 (2002)].

    Tirado-Soto, Magda Martina; Zamberlan, Fabio Luiz

    2013-04-01

    The objective of this study is to discuss the role of networks formed of waste-picker cooperatives in ameliorating problems of final disposal of solid waste in the city of Rio de Janeiro, since the city's main landfill will soon have to close because of exhausted capacity. However, it is estimated that in the city of Rio de Janeiro there are around five thousand waste-pickers working in poor conditions, with lack of physical infrastructure and training, but contributing significantly by diverting solid waste from landfills. According to the Sustainable Development Indicators (IBGE, 2010a,b) in Brazil, recycling rates hover between 45% and 55%. In the municipality of Rio de Janeiro, only 1% of the waste produced is collected selectively by the government (COMLURB, 2010), demonstrating that recycling is mainly performed by waste-pickers. Furthermore, since the recycling market is an oligopsony that requires economies of scale to negotiate directly with industries, the idea of working in networks of cooperatives meets the demands for joint marketing of recyclable materials. Thus, this work presents a method for creating and structuring a network of recycling cooperatives, with prior training for working in networks, so that the expected synergies and joint efforts can lead to concrete results. We intend to demonstrate that it is first essential to strengthen the waste-pickers' cooperatives in terms of infrastructure, governance and training so that solid waste management can be environmentally, socially and economically sustainable in the city of Rio de Janeiro.

Este estudo objetivou pesquisar as demandas de medicamentos considerados essenciais nas decisões da 2ª instância do Tribunal de Justiça do Estado do Rio de Janeiro, Brasil, em 2006. Foram analisados 185 processos e em três casos o pedido foi negado. Os tempos medianos entre início da ação e decisão liminar, sentença na 1a instância, e acórdão na 2ª instância, foram de 7, 239 e 478 dias, respectivamente. Em 98 processos o medicamento pode ser identificado e em 80,6% havia solicitação de ao menos um medicamento não pertencente aos elencos oficiais. Isto sugere que, além de problemas relacionados à aquisição, distribuição e dispensação de itens listados, os não selecionados em listas oficiais foram também grande motivação da demanda. Os medicamentos mais solicitados foram os dos sistemas cardiovascular e nervoso central.Recognition of the right to health raises two practical issues: the government's ethical and legal duty to ensure comprehensive health care and citizens' recourse to legal action to guarantee this right. This study focused on lawsuits to demand "essential" medicines, filed at the State Court of Appeals in Rio de Janeiro, Brazil, in 2006. One hundred and eighty-five suits were examined, and the claims were granted in all but three cases. Median times between filing the suit, the injunction, first ruling, and appellate ruling were 7, 239, and 478 days respectively. In 80.6% of the 98 suits in which the specific medicines could be identified, at least one drug did not belong to any publicly funded list of medicines. This could indicate that lawsuits demanding "essential" drugs were motivated not only by problems in procurement

    Pulmonary tuberculosis (PTB) remains a worldwide public health problem. Diagnostic algorithms to identify the best combination of diagnostic tests for PTB in each setting are needed for resource optimization. We developed one artificial neural network model for classification (multilayer perceptron-MLP) and another risk group assignment (self-organizing map-SOM) for PTB in hospitalized patients in a high complexity hospital in Rio de Janeiro City, using clinical and radiologic data collected from 315 presumed PTB cases admitted to isolation rooms from March 2003 to December 2004 (TB prevalence = 21.5 %). The MLP model included 7 variables-radiologic classification, age, gender, cough, night sweats, weight loss and anorexia. The sensitivity of the MLP model was 96.0 % (95 % CI ±2.0), the specificity was 89.0 % (95 % CI ±2.0), the positive predictive value was 72.5 % (95 % CI ±3.5) and the negative predictive value was 98.5 % (95 % CI ±0.5). The variable with the highest discriminative power was the radiologic classification. The high negative predictive value found in the MLP model suggests that the use of this model at the moment of hospital admission is safe. SOM model was able to correctly assign high-, medium- and low-risk groups to patients. If prospective validation in other series is confirmed, these models can become a tool for decision-making in tertiary health facilities in countries with limited resources.

    Sporotrichosis has emerged as the main subcutaneous mycosis of humans and animals around the world. With particular differences in frequency, the major species includes Sporothrix brasiliensis, S. schenckii, S. globosa and S. luriei. In Brazil, the main aspect of this epidemic is based on the zoonotic transmission through the scratches and bites of diseased cats contaminated with S. brasiliensis. Areas free of feline sporotrichosis are poorly characterised in Brazil. We investigated by molecular tools the epidemiology of human sporotrichosis in the Espírito Santo (ES) state, an area adjacent to Rio de Janeiro where is the epicentre of the long-lasting outbreak of cat-transmitted sporotrichosis. The human cases in the ES state reveal the prevalence of classical transmission types where subjects are mainly infected by accidental traumatic inoculation during manipulation of contaminated plant material. In agreement with an environmental source, Sporothrix schenckii was the major aetiological agent in the classical transmission. Unlike Rio de Janeiro, this study shows that cat-transmitted epidemic in Espírito Santo is still scanty, although the geographic proximity and similar climatic features. Sporothrix brasiliensis was the agent in the feline-transmitted cases. Sporothrix globosa was isolated from a patient with fixed cutaneous lesions that did not report any contact with diseased animals. In conclusion, beyond the borders of Rio de Janeiro epidemic, agents of sporotrichosis in Espírito Santo show a scattered occurrence with high species diversity. © 2015 Blackwell Verlag GmbH.

    Lutzomyia longipalpis is the main vector of Leishmania infantum chagasi in the Americas. Phlebotomine captures were conducted during 2008 and 2009 in a rural area endemic for cutaneous leishmaniasis located in the municipality of Saquarema, Rio de Janeiro. Among other species captured, we observed the presence of Lutzomyia longipalpis. This is the first report of the occurrence of Lutzomyia longipalpis in this region, demonstrating the potential risk of visceral leishmaniasis transmission in the coastal area of the State of Rio de Janeiro. Therefore, active vigilance by all municipalities in the area is necessary.

To analyze the time trend and evolution of murder charges, resistance to police resulting in death and missing persons rates, Joinpoint regression was performed, using these rates as the dependent variables and the calendar year as the independent variable. For the other categories only the time trends of the rates were analyzed for the relative change in rates at the beginning and end of the period. There were falls in rates in all categories, except for missing persons. The murder rate showed a significant downward trend in the three locations. The results contributed to definition of the pattern of violence in the three locations based on the dialogue between the social sciences, public health and safety that made it possible to establish subjective and objective aspects linked to the study findings.

    Polyclads are free-living Platyhelminthes with a simple, dorsoventrally flattened body and a much ramified intestine. In Brazil, 66 species are reported; only three from Rio de Janeiro State (RJ). The main objective of this study is to describe and illustrate coloration pattern, external morphology, reproductive system morphology and, when possible, biological and ecological aspects of species of the suborder Cotylea found in Cabo Frio, RJ. Of the 13 cotylean polyclad species found, Pseudobiceros pardalis, Cycloporus variegatus and Eurylepta aurantiaca are new records from the Brazilian coast and one species is new to science, Pseudoceros juani sp. nov. Feeding observations were made of four species. It is the first time that Lurymare utarum, Cycloporus gabriellae, C. variegatus and E. aurantiaca are illustrated with digital photographs of live specimens and histological preparations. This study increases to 70 the number of Brazilian Polycladida and to 14 the number of species known from Rio de Janeiro State. However, the knowledge about Polycladida in Brazil still has gaps, with great parts of the coast remaining unsampled.

    This work focuses on the export of trace metals and combustion residues from land to ocean and on the Southeast continental margin of Brazil and its historical variability using stable lead isotopes. Two sediment cores were collected, one in highly impacted Guanabara Bay and the other on the Southeast continental shelf. Continental shelf samples were analyzed for trace element concentrations [Mn (117±50 ppm), Ni (6.5±2.3 ppm), Zn (5.0±1.5), (233±46 ppm), ], Pb (5.4±2.4 ppm), as well as Cu, Ag, Cd, Sr, Ba, Tl, U and Pb isotope ratios & Pb-210. Most of the elements show higher concentrations on the upper part of the core compared to the bottom. Downcore changes of the concentrations of these elements were similar. The sediments of adjacent rivers and bays around the upper section of the southeast continental shelf of Brazil are considered highly enriched with Pb, Zn, Cu and Cr such as Guanabara Bay, Sepetiba Bay and Paraíba do Sul River compared with the natural concentrations and other regions in the world. A [Pb] maximum is seen between samples from 24 to 43 cm (~8 ppm). Utilization of tetraethyl lead (TEL) gasoline in Brazil was phased out beginning in 1983 and was largely completed by 1988. Continental shelf Pb-206/Pb-207 varies between 1.174 near the core top to 1.190 at 100 cm, with a sharp difference between samples at 6 and 8 cm. Higher core top Pb, Zn, and Ni corroborate the recent anthropogenic influence on the southeast continental shelf of Brazil. For Guanabara Bay sediment samples [Pb] varies between 90 ppm near the top to 1 ppm at the bottom. Pb-206/Pb-207 varies between 1.161 near the core top to 1.165 near the bottom. Using triple isotope plots we can discern different sources of lead to the region and how these vary with time.

    Full Text Available OBJETIVO: Analisar a freqüência da tuberculose e das outras principais doenças oportunistas definidoras de síndrome da imunodeficiência adquirida, no momento em que estes casos são notificados, no Município do Rio de Janeiro. MÉTODOS: Análise do banco de dados do Sistema de Vigilância Epidemiológica do Programa de Doenças Sexualmente Transmissíveis e Síndrome da Imunodeficiência Adquirida da Cidade do Rio de Janeiro, no período de 1993 a 2002. RESULTADOS: A expansão da definição de casos de síndrome da imunodeficiência adquirida ocorrida em 1998 criou um aumento substancial no número de casos notificados de síndrome da imunodeficiência adquirida, principalmente por aqueles que passaram a ser definidos pelo critério imunológico. Dentre os casos de síndrome da imunodeficiência adquirida que foram definidos apenas por doença, a candidíase em suas diversas formas manteve-se como a doença oportunista de maior freqüência no momento da notificação. Embora a pneumonia por Pneumocystis carinii se apresentasse como a segunda doença mais freqüente na maioria dos anos observados, a partir de 2001, a tuberculose ultrapassou-a em freqüência, tornando-se a segunda doença mais freqüente no momento da notificação dos casos de síndrome da imunodeficiência adquirida. CONCLUSÃO: Apesar da diminuição do número de casos de síndrome da imunodeficiência adquirida definidos por doença, a tuberculose manteve-se como um importante evento definidor dessa síndrome, sendo atualmente de ocorrência mais freqüente do que a pneumonia por Pneumocystis carinii e a toxoplasmose, provavelmente por sua alta taxa de prevalência na cidade.OBJECTIVE: To analyze the frequency of tuberculosis and of the other principal opportunistic infections defining acquired immunodeficiency syndrome at the time such cases were reported in the city of Rio de Janeiro, Brazil.

    Baía de Guanabara is a 384 km 2 eutrophic coastal bay in Brazil, impacted by the polluted discharge from the Rio de Janeiro metropolitan area. The structurally controlled bay has a central channel with a depth of 30 m and a sandy bottom near the entrance, reflecting wave and tidal forcing. In contrast, the bay-averaged water depth is 5.7 m and the bottom sediments are mostly muds as a result of the Holocene transgression and rapid fluvial sedimentation, accelerated by channelization of rivers and deforestation. An extensive sand bank is located seaward of the bay entrance and a flood-oriented sand wave system indicates sand transport into the bay. The mean freshwater discharge measures 100±59 m 3 s -1 and is greatest in the rainy austral summer in December and January. Tides are mixed mainly semidiurnal with a range of 0.7 m, and peak spring tidal currents reach 0.5 m s -1 inside the bay and 1.6 m s -1 near the bay entrance. The passage of northward propagating polar fronts results in regular strong southwesterly winds and heavy wave forcing. The bay has mean salinities from 21.0 to 34.5‰ with an average of 29.5±4.8‰. The vertical salinity stratification, Δs/s, varies from 0.06 to 0.21 and is relatively weak and inversely proportional to rms tidal currents. The residual circulation is characterized by both gravitational circulation and transverse residual tidal circulation, measuring 800 and 400 m 3 s -1 respectively. The renewal time of 50% of the bay water volume is 11.4 days. Untreated sewage runoff enters the bay from the west, resulting in locally poor water quality, where the near-bottom mean dissolved oxygen measures only 3.1 mg 1 -1 and results in anoxic bottom muds. The worst water quality is indicated by average fecal coliform of 1140 counts ml -1 and excessive ammonia and phosphate loading. The average chlorophyll concentration in this region responds to the nutrient loading and exceeds 130 μg 1 -1 although 57 μg 1 -1 is the overall mean for

    In Brazil, the rate of cervical cancer remains high despite the availability of screening programs. With ongoing vaccine development and implementation, information on the prevalence of specific HPV types is needed, particularly among high-risk populations, such as HIV-infected women. We performed a study of HIV-infected women in Rio de Janeiro, Brazil, who underwent cervical HPV genotype testing between 2005-2013. We examined the prevalence of high-risk HPV types and the patterns of high-risk HPV type clustering. Using logarithmic binomial regression, we estimated the risk of abnormal cytology by HPV genotype result. Of the 562 women included, 498 (89 %) had at least one HPV type detected. 364 women (65 %) had at least one high-risk HPV type detected and 181 (32 %) had more than one high-risk type detected. HPV 58 was the most frequent HPV type detected overall (prevalence 19.8 % [95 % confidence interval 16.4–23.1]), followed by HPV 53 (prevalence 15.5 % [12.5–18.5]) and HPV 16 (prevalence 13 % [10.2–15.8]). Women infected with more than one high-risk HPV type were younger, had lower CD4+ lymphocyte counts, and were more likely to be infected with HPV 16 or 18. In adjusted analyses, presence of more than one high-risk HPV type was associated with a two-fold increased risk of abnormal cytology after adjusting for presence of individual high-risk type, age, and CD4+ lymphocyte count (adjusted prevalence ratios 1.88–2.07, all p <0.001). No single high-risk HPV type was statistically associated with abnormal cytology after adjusting for the presence of more than one high-risk HPV type. In the largest study of cervical HPV genotypes among HIV-infected women in Latin America, infection by high-risk HPV types other than 16 or 18 and infection by more than one high-risk HPV types were common. Infection by more than one high-risk type was more strongly associated with abnormal cervical cytology than any individual high-risk HPV type, highlighting the need for

    Full Text Available In addition to the structural reforms that inaugurated elements in the public management of the State Department of Education of Rio de Janeiro (SEEDUC, expressed through goals established in its strategic planning, was also presented the Integrated School Management (GIDE, a system of management that covers strategic, political and managerial aspects of the educational area with focus on results. According to SEEDUC, through the implementation of GIDE each school unit would have a diagnosis of their situation and could give priority to the causes of the problems, helping the state to raise its results in the Index of Development of Basic Education (IDEB. In this sense, we observe the close link between GIDE and target culture, which ultimately leads to the elevation of IDEB. Under careful analysis it is possible to identify that the emphasis on managerial aspects is associated with performativity. Thus, the present text intends to present the proposal of GIDE, to relate it to the managerial context of the educational policy of Rio de Janeiro, and to reflect on the implications of the introduction of a new model of educational management in the State.

    Full Text Available Thirty-eight stations were sampled in Guanabara Bay, Rio de Janeiro, Brazil, to assess the spatio-temporal diversity and biomass of sublittoral polychaetes. Samples were collected during the dry (September 2000 and rainy season (May 2001 in shallow sublittoral sediments. The polychaete spatial composition showed a heterogeneous distribution throughout the bay. A negative gradient of diversity and biomass was observed towards the inner parts of the bay and sheltered areas. A wide azoic area was found inside the bay. Some high-biomass and low-diversity spots were found near a sewage-discharge point. In these areas, the polychaete biomass increased after the rainy season. A diversified polychaete community was identified around the bay mouth, with no dramatic changes of this pattern between the two sampling periods. Deposit-feeders were dominant in the entire study area. The relative importance of carnivores and omnivores increased towards the outer sector, at stations with coarse sediment fractions. Guanabara Bay can be divided into three main zones with respect to environmental conditions and polychaete diversity and biomass patterns: A High polychaete diversity, hydrodynamically exposed areas composed of sandy, oxidized or moderately reduced sediments with normoxic conditions in the water column. B Low diversity and high biomass of deposit and suspension-feeding polychaete species in the middle part of the bay near continental inflows, comprising stations sharing similar proportions of silt, clay and fine sands. C Azoic area or an impoverished polychaete community in hydrodynamically low-energy areas of silt and clay with extremely reduced sediments, high total organic matter content and hypoxic conditions in the water column, located essentially from the mid-bay towards the north sector. High total organic matter content and hypoxic conditions combined with slow water renewal in the inner bay seemed to play a key role in the polychaete

    Road transportation has contributed to increased emissions of conventional air pollutants and, consequently, to the increase in problems associated with the environment and human health, depending on the type of pollutant and the concentration of it. To support the development of public policies aimed to decrease total tonnes of emissions, we used a bottom-up approach to estimate the amount of air pollutants, such as carbon monoxide (CO), total hydrocarbons (THC), nitrogen oxides (NO x ), particulate matter (PM), and aldehydes (RCHO), that are emitted by road transportation in the state of Rio de Janeiro (RJ) from 1980 to 2010. The results from 2010 show that cars are responsible for 55% of CO emissions, 61% of THC emissions, and 93% of RCHO emissions. Due to the use of hydrated ethanol and compressed natural gas (CNG) instead of petroleum based fuels during the period analyzed, 1,760,370 t of air pollutant emissions were avoided. Compared to Brazil, in 2010, RJ had a quantity of emissions per vehicle from 12% (CO) to 59% (PM) smaller than the national average. As strategies to reduce air pollutant emissions, we consider reducing the intensity of use, with a proportional reduction in emissions, and increased the use of biodiesel. - Highlights: ► We estimate road transportation emissions for Rio de Janeiro from 1980 to 2010. ► C gasoline was most responsible for CO (74%) and diesel for PM (91%). ► Emissions/vehicle for Rio de Janeiro are (12% to 59%) smaller than Brazilian. ► 1,760,370 t of emissions was avoided using non-petroleum-based fuels. ► Strategies to reduce the emissions of these air pollutants were proposed.

    According to the Brazilian National Database there are about 300 Nuclear Medicine Services (NMS) in Brazil, 44 of them located in the State of Rio de Janeiro (RJ). Individual dose measurements are an important input for the evaluation of occupational exposure in order to demonstrate the effectiveness of radioprotection implementation and to keep individual doses as low as possible. In Brazil, most nuclear medicine (NM) staff is routinely monitored for external dose. The internal committed dose is estimated only in abnormal conditions. This paper makes a statistics analysis of all the RJ NMS annual external occupational doses in year 2005. A study of the evolution of monthly external individual doses higher than 4.00 mSv from 2004 to 2008 is also presented. The number of registered thorax monthly dose higher than 4.0 mSv is increasing, as its value. In this period the highest dose measured reaches 56.9 mSv, in one month, in 2008. About 50% of the annual doses are smaller than the monthly record level of 0.20 mSv. In 2005, around 100 professionals of RJ NMS received annual doses higher than 4.0 mSv, considering only external doses, but no one receives doses higher than 20.0 mSv. Extremities dosimeters are used by about 15% of the staff. In some cases, these doses are more than 10 times higher than the dose in thorax. This study shows the importance to improve radiation protection procedures in NM. (author)

    Full Text Available Seabirds play a significant role as bioindicators: they are conspicuous, relatively easy to observe, well-established studied group of organisms, and in the focus of public interest due to pollution in aquatic ecosystem. Systematically, a significant number of man-made chemicals have been introduced in the marine environment and represent the major problem arising in the development worldwide. Many of these chemical contaminants are persistent, known to bioaccumulate and biomagnify through the aquatic food web, affecting species associated with aquatic systems. Dioxins [polychlorinated dibenzo-p-dioxins (PCDD, dibenzofurans (PCDF] and polychlorinated biphenyls (PCB concentrations were measured in Kelp gull Larus dominicanus collected from 2006 to 2011 on Marambaia Island, Sepetiba Bay, Rio de Janeiro State, Brazil. Detectable liver concentrations of PCDD Fs-1 and PCBs were found in all samples analyzed. These represent some of the first measurements of PCDD Fs-1 and PCBs in seabirds from this area. Although levels of these contaminants in the tested species currently appear to fall below critical values, a continuous and systematic monitoring on these compounds becomes essential and desirable to not express toxic values in the future.

    Full Text Available Objective. To estimate rates of lower extremity amputations (LEAs in persons with peripheral vascular disease, diabetes mellitus, trauma, neoplasm, osteomyelitis, or emphysematous gangrene. Methods. Regional amputee registries were used to estimate the rate of lower extremity amputations with the capture-recapture (CR technique. Data were extracted from three amputee registries in Rio de Janeiro: source 1, with 1 191 cases from 23 hospitals; source 2, with 157 cases from a limb-fitting center; and source 3, with 34 cases from a rehabilitation center. Amputee death certificates from source 1 identified 257 deaths from 1992 to 1994. Three CR models were evaluated using sources 2 and 3. In order to avoid an overestimation of the rate of LEAs, two models were applied for the data analysis: in one case, deceased patients listed in source 1 were excluded from the model, and in the other case, deceased patients were included as well. Results. Excluding the 257 deaths, the estimated number of amputations in the municipality of Rio de Janeiro from 1992 to 1994 was 3 954, for a mean annual incidence rate of 13.9 per 100 000 inhabitants. Among persons with diabetes, the annual incidence rate of lower extremity amputations was substantially higher (180.6 per 100 000 persons per year, representing 13 times the risk of individuals without diabetes. The yearly rate of LEAs according to the routine surveillance system was estimated at 5.4 and 96.9 per 100 000 in the general population and in diabetics, respectively. If data from the three registries are added, 1 382 patients with LEAs were identified, with the reasons for the amputations distributed as follows: peripheral vascular disease = 804 (58.1%; diabetes mellitus = 379 (27.4%; trauma = 103 (7.4%; osteomyelitis = 44 (3.1%; gangrene = 36 (2.6%, and neoplasm = 16 (1.1%. Conclusions. These findings show a high incidence of LEAs in Brazil, when compared to countries such as Spain, that is attributable mainly

    Full Text Available Botulism is a rare and potentially lethal illness caused by Clostridium botulinum neurotoxin. We describe the findings of a laboratorial investigation of 117 suspected cases of botulism reported to the surveillance system in Brazil from January 2000 to October 2008. Data on the number and type of samples analyzed, type of toxins identified, reporting of the number of botulism cases and transmission sources are discussed. A total of 193 clinical samples and 81 food samples were analyzed for detection and identification of the botulism neurotoxin. Among the clinical samples, 22 (11.4% presented the toxin (nine type A, five type AB and eight with an unidentified type; in food samples, eight (9.9% were positive for the toxin (five type A, one type AB and two with an unidentified type. Of the 38 cases of suspected botulism in Brazil, 27 were confirmed by a mouse bioassay. Laboratorial botulism diagnosis is an important procedure to elucidate cases, especially food-borne botulism, to confirm clinical diagnosis and to identify toxins in food, helping sanitary control measures.Botulismo é uma doença rara e potencialmente letal, resultante da ação de uma neurotoxina produzida pelo Clostridium botulinum. No presente estudo, estão descritos os resultados da investigação laboratorial de 117 casos suspeitos de botulismo notificados ao sistema de vigilância, ocorridos no Brasil no período de janeiro de 2000 a outubro de 2008. Os dados obtidos sobre as fontes de transmissão, os tipos de toxina identificados e de amostras analisadas serão discutidos. Foram analisadas 193 amostras clínicas e 81 amostras de alimentos para detecção e identificação de neurotoxina botulínica. Entre as amostras clínicas, 22 (11,4% amostras apresentaram resultado positivo para toxina (nove do tipo A, cinco do tipo AB e em oito o tipo não foi identificado e entre as amostras de alimentos, oito (9,9% foram positivas (cinco do tipo A, uma do tipo AB e em duas o tipo n

    Full Text Available Between June 4th and June 20th1996 rotavirus, adenovirus, and astrovirus (HAstrV were investigated in fecal samples from 27 children under three years old with acute diarrhea, attending the Bertha Lutz day care center, in Rio de Janeiro. All fecal samples were analyzed by polyacrylamide gel electrophoresis (PAGE, reverse transcriptase polymerase chain reaction (RT-PCR, enzyme immunoassays (EIA, and electron microscopy (EM. Nine of them (33% showed positive results for HAstrV by at least one of the employed methodologies. Eight were positive by RT-PCR and EIA, and six by EM. All positive samples were inoculated onto HT-29 (human colon adenocarcinoma cultured cells for HAstrV isolation and seven were positive after three passages. The sequencing analysis of eight RT-PCR products (449 bp from gene that codifies VP2 protein, showed a total nucleotide identity among them and 98% with HAstrV-1 (strain Oxford type 1. This is the first report of a gastroenteritis outbreak associated with HAstrv-1 in a day care center in Rio de Janeiro and it reinforces the importance of this virus in association with infantile acute gastroenteritis.

    Full Text Available The political history of the Museu do Índio, founded in 1953 in Rio de Janeiro under the institutional guiding of the anthropologist Darcy Ribeiro, enables to establish some social relations with elements of nature in Brazil. The study of the initial moment of the constitution of this cultural heritage, its history and the disputes it begot, even in memory, starts from the notion of "deceptive coherence" of a generation of ethnologists, intellectuals and of the military and the Brazilian National State policies in the 50s. The consulted sources and documentation are journalistic, bibliographic and archivistic.

    Full Text Available Schistosomiasis constitutes a major public health problem, with an estimated 200 million people infected worldwide. Many areas of Brazil show low endemicity of schistosomiasis, and the current standard parasitological techniques are not sufficiently sensitive to detect the low-level helminth infections common in areas of low endemicity (ALEs. This study compared the Kato-Katz (KK; Hoffman, Pons, and Janer (HH; enzyme-linked immunosorbent assay- (ELISA- IgG and ELISA-IgM; indirect immunofluorescence technique (IFT-IgM; and qPCR techniques for schistosomiasis detection in serum and fecal samples, using the circumoval precipitin test (COPT as reference. An epidemiological survey was conducted in a randomized sample of residents from five neighborhoods of Barra Mansa, RJ, with 610 fecal and 612 serum samples. ELISA-IgM (21.4% showed the highest positivity and HH and KK techniques were the least sensitive (0.8%. All techniques except qPCR-serum showed high accuracy (82–95.5%, differed significantly from COPT in positivity P<0.05, and showed poor agreement with COPT. Medium agreement was seen with ELISA-IgG (Kappa = 0.377 and IFA (Kappa = 0.347. Parasitological techniques showed much lower positivity rates than those by other techniques. We suggest the possibility of using a combination of laboratory tools for the diagnosis of schistosomiasis in ALEs.

    Full Text Available The purpose of this paper is to analyze the National Memorial to the World War II Dead (1956-60, a monument designed by Marcos Konder Netto and Hélio Ribas Marinho, and located in Flamengo Park, Rio de Janeiro. We start by commenting on the debates that were going on within the Modernist movement about the need for a new monumentality. Then, we examine the memorial against the urban landscape of Rio de Janeiro and its specific architectural language. Finally, we make an effort to explain the apparent paradox found in modern monuments.

    Full Text Available El artículo analiza la percepción de un grupo de jóvenes de las capas populares de Río de Janeiro, Brasil, sobre las repercusiones de programas sociales en sus trayectorias afectivo/sexual y escolar/profesional. Desde una perspectiva comparativa, examinamos las visiones, las prácticas y las condiciones de vida de 42 chicos y chicas, entre 18 y 24 años, con y sin participación en proyectos sociales dirigidos a la profesionalización y promoción de la ciudadanía. Son discutidos, particularmente, los impactos de las intervenciones en las concepciones de salud y SIDA, en los indicadores de movilidad social y profesionalización y en la formación de redes sociales, incluyendo la dimensión de género. Buscamos reflexionar sobre los efectos de organizaciones civiles en la población juvenil de baja renta, en un contexto de crisis socioeconómica y de pocos avances en términos de políticas sociales. Destacamos que, a pesar de las limitaciones de tales intervenciones en el contexto macro social, la experiencia de apoyo social promovida por los proyectos contribuye a la ampliación de la perspectiva de vida y del capital simbólico de este grupo social, con impactos positivos para la esfera de la salud.This article analyzes the perceptions of a group of youth from the lower economic levels of Rio de Janeiro, Brazil, about the repercussions of social programs on their affective/sexual and educational/professional trajectories.

  15. Potential geographic distribution and conservation of Audubon's Shearwater, Puffinus lherminieri in Brazil

    Full Text Available Audubon's Shearwater (Puffinus lherminieri Lesson 1839 is a tropical seabird occurring mainly between southern Canada and the southeast coast of Brazil. Puffinus lherminieri is considered Critically Endangered on the Brazilian Red List because it only occurs in two known localities, both of which contain very small populations. However, many offshore islands along the Brazilian coast are poorly known and the discovery of new colonies would be of considerable significance for the conservation of this species. The aim of this study was to estimate the potential geographic distribution of Audubon's Shearwater in Brazil, based on ecological niche model (ENM using Maxent algorithm with layers obtained from AquaMaps environmental dataset. The ENM was based on 37 records for reproduction areas in North and South America. The model yielded a very broad potential distribution, covering most of the Atlantic coast ranging from Brazil to the US. When filtered for islands along the Brazilian coast, the model indicates higher levels of environmental suitability near the states of São Paulo, Rio de Janeiro, Espírito Santo and Bahia. However, P. lherminieri prefers islands in environments with warm saline water. Thus, based on the influence of currents that act on the Brazilian coast we can infer undiscovered colonies are most likely to occur on islands on coast of Bahia, Espírito Santo and extreme north of the Rio de Janeiro. These should be intensively surveyed while the islands south of Cabo Frio should be discarded. The existence of new populations would have profound effects on the conservation status of this enigmatic and rarely seen seabird.

Este estudo analisou os teores de ácidos graxos trans, saturados, monoinsaturados e poliinsaturados em batatas fritas, biscoitos e sorvetes. As batatas fritas foram dos tipos chips e de duas redes de fast food, os sorvetes, de duas marcas comerciais e de duas lojas de fast food, e os biscoitos, de marcas diferentes. As amostras de batatas chips e de biscoitos pertenciam a lotes distintos e foram adquiridas em supermercados da região. Analisaram-se seis amostras por produto, através de cromatografia gasosa. O valor médio dos ácidos trans de batatas fritas de redes de fast food foi de 4,74g/100g, enquanto em batatas chips estes ácidos graxos não foram detectados. Nos sorvetes os valores variaram de 0,041g a 1,41g e em biscoitos, de 2,81g a 5,60g. Biscoitos tipo cream cracker apresentaram teores de ácidos graxos trans mais altos e de insaturados mais baixos. Concluiu-se que alguns produtos apresentaram, em 100g, teores de ácidos graxos trans superiores aos recomendados para ingestão total diária em diversos países.The content of trans fatty acids in most consumed foods in Brazil is unknown. This study assessed trans saturated, monounsaturated and polyunsaturated fatty acids in samples of fried potatoes, cookies and ice cream. The analysis included: potato chips and fried potatoes from two popular fast food restaurants, ice cream of two different trademarks and from two fast food restaurants, and cookies of different trademarks.

    Full Text Available A mortalidade fetal, apesar de elevada no Brasil, é pouco estudada quanto à sua determinação. Um estudo caso-controle aninhado foi feito para investigar os determinantes da mortalidade fetal em uma população usuária dos serviços públicos de uma região do Rio de Janeiro, de 2002 a 2004. Os dados foram coletados por meio de entrevista com as puérperas e complementados em prontuários e cartões de pré-natal. Os casos foram óbitos fetais com peso igual ou superior a 500g e os controles foram nascidos vivos no mesmo período. Para análise estatística, usou-se um modelo hierárquico de fatores sócio-econômicos e psicossociais (nível distal, reprodutivos, comportamentais e assistenciais (intermediário e características biológicas do feto (proximal. Destacaram-se vínculo empregatício, situação marital estável, acompanhante na admissão e pré-natal adequado como protetores de mortalidade fetal, enquanto violência doméstica, morbidade na gravidez e crescimento fetal restrito aumentaram o risco. O pré-natal se mostrou importante estratégia de redução do risco nesta população.Stillbirth rate is high in Brazil, and it is important to identify its determinants. A nested case-control was conducted to explore the determinants of fetal death in a population treated at public services in Rio de Janeiro from 2002 to 2004. Data were collected from mothers' interviews and medical records. A structured model was proposed to perform statistical analysis, attributing hierarchical levels: socioeconomic factors (distal level, reproductive, behavioral, and healthcare determinants (intermediate level, and fetal biological characteristics (proximal level. According to the findings, work stability, stable marital status, presence of a companion during admission, and adequate prenatal care had a protective effect against fetal death, while domestic violence, maternal morbidity, and intrauterine growth restriction increased the risk.
