O tempo das brincadeiras : memória, turismo e tradição em Barra do Camaratuba PB

Barra do Camaratuba belongs to Mataraca city, nearby the boarder between Paraíba and Rio Grande do Norte states. It was the chosen community to develop this research, objectifying to study the set of practical of the cultural manifestations and the implications of the local tourist activity, considering the cultural dynamics. We tried to reconstruct stories from the narratives of the oldest inhabitants, natives, among others that they had lived, some how, individual and collective experiences related to the popular tricks and the traditional parties, considering what they speak and imagine about their experiences and its culture. The Lapinha, the Pastoril, the viola s songs, the Balls of Concertina, the João Redondo, the Ox of Kings, the wheel of Coconut were common practical perceivable through the communitarian bonds. Among these manifestations, the only one that resisted for a longer time was the wheel coconut. The São Pedro s fest is another popular manifestation that appears on the current scene like the padroeiro party, while others cultural practical compose the spectacle s scenery. These questions cover many of the narratives of the interviewed ones in the interlaced thing between memory, tourism and tradition. Therefore, we tried to build our research from the memory, participant observation, orality, techniques of the life history, personal depositions, among others basic methods for the reconstruction of a collective memory . Speaking about the past of Barra do Camaratuba is to live again the parties, the blood relations, the terço , the work in the roçados , in the flour house, the fishing, the leisure and the habits of the daily life. In this community, there is the presence of conflicts of social and cultural order, caused for the hegemonic classes that sponsor the parties. In the padroeiro party we perceive that the mercantile logic has started, very recently, to transform the religious factor into an excuse to put into motion the local economy. This way, a community originated from artisan fishers and agriculturists, having the fishing practical as a way of subsistence and the tricks as a reference, they had started to compose a new social picture with the arrival of the others and with the presumption and recent tourist development. We perceive social, environmental and cultural impact transformations, exemplified by a non planned activity or a predatory tourism. The changes will always be pointed and compared with other passing in a sphere of relations lived by the natives, local players and fishers

Etnobiologia do boto cinza (Sotalia guianensis, van Bénéden, 1864) por comunidades pesqueiras do Rio Grande do Norte, Basil

Ethnobiology studies Local Ecological Knowledge (LEK) as well as the use and management of natural resources by local communities in order to understand how the environment is perceived, known and classified by human groups. In fishing communities, LEK adds empirical information about the biology of aquatic species and complements scientific findings, especially when it is difficult to obtain factual information during studies on cetaceans, whose behavior is essentially underwater. Cetaceans (whales and dolphins) are constantly threatened by human activities, especially by accidental capture of small coastal species, as in the case of the estuarine dolphin (Sotalia guianensis), object of this study. Ethnobiological researches in fishing communities are of great importance and can clarify aspects of the biology and conservation of this species. Although extensively studied throughout its distribution range, there are still gaps in the knowledge about S. guianensis. Therefore, fishers local ecological knowledge becomes an additional tool to get and confirm information about S. guianensis. This study evaluated the LEK of artisanal fishers who are daily exposed to local population of S. guianensis, through the use of semistructured interviews (N=116). The interviewed fishers were asked about the biology and popular classification of S. guianensis and about possible interactions between this dolphin and them. The studied communities were located in Tibau do Sul (n=39), Pipa (n=36) and Baía Formosa (n=41), all on the south coast of Rio Grande do Norte, Brazil. The study was based on the assumption that differences in fishers LEK among those communities would be caused by both the variety of fishing environments (lagoon/estuary and ocean) and the intensity of tourism activities. Fishers knowledge is expressive and differed among the studied communities depending on the topic investigated. Fishers correctly reported the habitat, distribution, seasonality and behavioral particularities of S. guianensis. Tourism mainly affected the naming of the species. The study results also suggest that marine fishers have greater knowledge about the species than the estuarine/lagoon ones. Local populations accumulate empirical knowledge according to their environment. Hence, it is important to take into account both empirical knowledge and popular participation in management systems, in order to maintain information sharing among communities

Perfil imuno-histoquímico do infiltrado inflamatório no front de invasão em carcicomas epidermóides de língua e lábio inferior

The progression of the oral squamous cells carcinomas (OSCCs) seems to suffer influence from related factors to the host, as local and systemic immunologic response, which are essential to the antineoplasic defenses. The purpose of this study was evaluate the local immunity in 30 tongue and 20 lower lip SCC by immunohistochemistry method, utilizing antibodies anti-CD3, CD4, -CD8, -CD25 e -ζ(zeta), which immunoexpressions were compared considering the anatomical localization, the intensity of the inflammatory infiltrate into the front of invasion and metastases. The CD4/CD8+ ratio was calculated for each case and associate with the mentioned variable, being the intensity of the inflammatory infiltrated also compared with the anatomical localization and metastase and for this the cases had been grouped in two categories: (n = 10) absent/scarce inflammatory infiltrate; and (n = 40) moderate/intense infiltrate. Fisher´s exact test was performed (α= 0.05) and it was not observed any significant correlation between these groups with anatomical sites and metastases. With regard to the immunoexpression, the CD3+, CD4+, CD8+ and CD25+ cells count was higher in the lower lip SCCs while the anti-ζimmunomarcation was more evident in the non metastatic cases. Through the statistical analyses, it was verified that the CD3 exhibited positive-significant correlation with the inflammatory infiltrate (p = 0.023). Furthermore, antibodies against CD8 and CD25 cells were also significantly correlated with the inflammatory infiltrate (p = 0.002 and 0.030, respectively) and with the anatomical site (p = 0.004 and p = 0.004) mainly in the lower lip SCCs. CD4/CD8 ratio did not show significant association with metastase nor with anatomical localization. We conclude that the inflammatory infiltrated of the Bryne s (1998) system did not constitute an indicator of aggressiveness in the tongue and lower lip SCCs analyzed and that clinical behavior of the SCCs studied was related in part to the immunohistochemical profile of infiltrated the inflammatory present in tumoral invasion front

Avaliação do potencial de toxicidade de florações de cianobactérias como subsídio para ações de gestão ambiental em açudes do semiárido potiguar

Blooms negatively compromise the aquatic environment, plants, animals and human health.Some species are toxin-producing, such as the neurotoxin saxitoxin and the hepatotoxin microcystin, which may contaminate water reservoirs, as those existing in the semiarid region of Rio Grande do Norte (Brazil) which are used to supply the population, fishing, aquiculture and recreational activities, thereby providing the risk of human exposure through water intake, dermal contact and respiratory tract. Thus, it is recommended a constant monitoring of the density of cyanobacteria with the quantification of cyanotoxins. One goal with this work was the monitoring of water in four reservoirs in semiarid of RN through the identification and enumeration of cyanobacteria and through the identification and quantification of cyanotoxins by ELISA. Furthermore, we intended to assess the environmental perception of farmers and artisanal fishers in reservoirs of semiarid of RN through semi-structured interviews with questions mostly related to water and eutrophication. Through these objectives the aim was the development of management strategies for aquaculture and prevention of risks to public health. The results showed that the highest values of microcystins were found in the rainy season. Standards for drinking water, according to the guidelines of Ministry of Health 2914/2011 and CONAMA 357/05, setting the maximum values for raw water density of cyanobacteria: 50,000 cel.mL-1; microcystin: 1 μg. L-1 and saxitoxin: 3 μg. L-1. The values found for microcystin ranged between 0.00227 μg. L-1 and 24.1954 μg. L-1. From 128 samples analyzed, 27% were above the limit. There was no clear seasonal pattern for saxitoxins and their values ranged between 0.003 μg. L-1 and 0.766 μg. L-1 with none of the values above the limit. Furthermore, 76% of the densities of cyanobacteria values were above the limit. About environmental perception, 52 interviews were conducted and the results show that the respondents recognize the main uses of water of the rervoirs, recognize the importance and have a positive view about the reservoirs. They also realize that the water has a poor quality and can cause health problems. The results provide data showing the persistence of cyanobacteria and cyanotoxins, many times over the limit, reinforcing the importance of constant monitoring. The assessment of environmental perception gives foundation for later proposed environmental education linked to public health management into the context of this particular population, making it more effective

Agroindústria canavieira e unidade de conservação: Impactos Sociais na comunidade de pescadores de Baía Formosa (RN)

The conservation unities emerged in response to the environmental damages. In the Atlantic Forest of the Brazilian Northeast, the most of the damages come from the sugar-cane agro-industry, especially by the deforestation for the introduction of sugar-cane fields and installation of the industry structure. Besides the damages over the biodiversity, there are critical social problems that affect the communities which survive using directly or indirectly the biome from the Atlantic Forest. The objective of this research is to analyze the social impacts on the fishermen of Baía Formosa/RN generated by the changes and socio-environmental transformations occurred starting the installation of a sugar-cane factory and the creation of a conservation area in the municipality of Baía Formosa/RN community. The research is based on a qualitative and diachronic perspective, for both approach, it was used the method of oral history in conjunction with the literature search and some technical and research tools such as direct observation, interview, records images and recordings . The results show that social and symbolic practices of the community in the conservation unit Mata Estrela last more strongly presented. Today fewer natural resources are used, due to factors such as limit access to forest and disappearance of some natural resources by deforestation. It is believed that the loss of free access to space for the community is the most significant negative impact, as promoted changes in the relationship of the community with the Star Forest that contributed to the fading of their social and symbolic practices. The loss of free access caused the decline in the practice of agriculture, which resulted in the loss of one of the means of social reproduction of the community

Ecologia humana e manejo participativo da pesca do búzio Anomalocardia brasiliana (Gmelin, 1791) (Bivalvia: Veneridae) na Reserva de Desenvolvimento Sustentável Estadual Ponta do Tubarão (RN)

Coastal and marine protected areas are created to protect habitat, avoid biodiversity loss, and to help maintain viable fisheries. However, most of these areas in tropical countries occurs in impoverished regions and directly affect the livelihood and survival of coastal communities which directly depend on fisheries and shellfisheries. Therefore, socioeconomic and conservation goals overlap. In this context, fishers should have a central place in resource management. They are critical resource users and their behavior directly affects the system. Shellfish resources are important sources of food, employment and income to fishing communities in Latin America. But despite its widespread use for food and income, there is an urgent need of more research on shellfish management. This research discusses the artisanal fisheries of Venus clam (Anomalocardia brasiliana) (Gmelin, 1791) (Bivalvia: Veneridae) in Brazil, and points out strategies to improve the system. Venus clam is a small and commonly exploited species for food and income on the Brazilian coast. This research was carried out at Ponta do Tubarão Sustainable Development Reserve (Brazilian Northeast coast), where there was no information available about who harvest, where or how much Venus clam has been harvested, despite this resource being exploited for generations. Clam fishery follows the pattern of socio-economic invisibility that general clam exploitation has in Brazil. Methods used were interviews, participatory monitoring and focal follow observation from January 2010 to May 2011. Results include: (a) the identification of shell fishers, (b) how harvest and meat processing are performed (mollusk beds, time spent, gross and net production), (c) the analisis of shell fisher income and their economic sustentability, and (d) the involvement of shell fisher families in data gathering and analyses for the first time. Based on the acquired knowledge, we propose a new institutional arrangement for clam fishery including co-management, fisheries agreement, compensatory arrangements and improvements for the Venus clam value chain such as the establishment of a minimum price for clam meat. This research also includes two other results: a general description for Venus clam harvesting in the Brazilian Northeast coast and a specific discussion about co-management of Venus clam in Brazil. The first one was possible through the meeting of several shell fisherwomen from other states during activities promoted by People of the Tides (PoT) project. PoT was an international initiative aiming to develop coastal communities that depend on mollusk for their livelihood. The second one is a comparison between PoT and Venus clam management at Pirajubaé Marine Extractive Reserve (Santa Catarina). It evaluates the success and failures of these only two initiatives involving co-management of A. brasiliana in Brazil

Avaliação da qualidade da assistência à mulher e ao filho durante o parto normal

The practices developed in the everyday life of obstetric services are sometimes out of step with the recommendations of the public health policies. Accordingly, this research had the objective of assessing the quality of the care provided to women and children during cases of natural childbirth in municipal public maternity wards of the city of Natal/RN, Brazilian Northeast. We developed a cross-sectional and quantitative study in two maternity wards that provide care actions to pregnant women at regular risk (maternity wards A and B). The participants were 314 puerperal women who were treated during the period between April and July 2014, whose children were born alive, through transpelvic way, with spontaneous or induced beginning of labor and that showed physical and emotional conditions to respond to the proposed questions. The data collection instrument was constructed on the basis of the recommendations of the World Health Organization focused on the care of normal childbirth and validated by skilled judges, and the final version has obtained optimum agreement (k = 0,96; IVC = 0,99). Associated with these recommendations, we used three indicators: percentage of women with induced labor or subjected to elective cesarean section (Indicator A); percentage of women served by a qualified health professional during labor and childbirth (Indicator B); and Bologna Index (Indicator C). The research obtained a favorable opinion of the Research Ethics Committee from the Federal University of Rio Grande do Norte, under the nº 562.313 and Certificate of Presentation for Ethics Appreciation: 25958513.0.0000.5537. The analysis of categories related to the recommendations of the World Health Organization was conducted by means of absolute and relative frequency and the Chi-square Pearson’s and Fisher’s exact tests made the comparison of the differences observed between the two maternity wards. Furthermore, we calculated the percentage of the indicators A and B and with the results of the Indicator C, the quality was assessed as follows: the closer to 5, the better will be the quality, and the closer to 0, the worst will be the quality, and the Mann-Whitney U test was used to compare the differences of the obtained averages. The significance level of 5% was considered in all statistical tests. The differences between the maternity wards were identified with regard to the provision of liquids orally (p=0,018), stimulus for non-supine positions (p=0,002), existence of partograph (p=0,001), support or welcoming by health professionals (p= 0,047), intravenous infusion (p<0,001), supine position (p<0,001), use of oxytocin (p<0,001), food and liquid restriction (p= 0,002) and, lastly, the fact of the touch is performed by more than 1 examiner (p=0,011). The indicators A and B showed percentages of 13,09% and 100%, respectively. The overall average of the Indicator C was equal to 2,07 (± 0,74). There was a statistically significant difference between the averages of the maternity wards (p<0,001). The care actions provided during the process of labor and childbirth is inappropriate, especially in the maternity ward B. It is necessary to implement improvements and redesign the obstetric model in force

Economy of the island of eco-tourism: the role of shark-diving and shark harvesting

Beyond its importance in maintaining ecosystems, sharks provide services that play important socioeconomic roles. The rise in their exploitation as a tourism resource in recent years has highlighted economic potential of non-destructive uses of sharks and the extent of economic losses associated to declines in their population. In this work, we present estimates for use value of sharks in Fernando de Noronha Island - the only ecotouristic site offering shark diving experience in the Atlantic coast of South America. Through the Travel Cost Method we estimate the total touristic use value aggregated to Noronha Island by the travel cost was up to USD 312 million annually, of which USD 91.1 million are transferred to the local economy. Interviewing people from five different economic sectors, we show shark-diving contribute with USD 2.5 million per year to Noronha’s economy, representing 19% of the island’s GDP. Shark-diving provides USD 128.5 thousand of income to employed islanders, USD 72.6 thousand to government in taxes and USD 5.3 thousand to fishers due to the increase in fish consumption demanded by shark divers. We discover, though, that fishers who actually are still involved in shark fishing earn more by catching sharks than selling other fish for consumption by shark divers. We conclude, however, that the non-consumptive use of sharks is most likely to benefit large number of people by generating and money flow if compared to the shark fishing, providing economic arguments to promote the conservation of these species.

Avaliação da efetividade do Programa de Alimentação do Trabalhador

This study analyzed the Worker’s Healthy Eating Program in Rio Grande do Norte state (RN) to assess its possible impact on the nutritional status of the workers benefitted. To that end, we conducted a cross-sectional observational prospective study based on a multistage stratified random sample comparing 26 small and medium-sized companies from the Manufacturing Sector (textiles, food and beverages, and nonmetallic minerals) of RN, divided into two equal groups (WFP and Non WFP). Interviews were conducted at each company by trained interviewers from Tuesday to Saturday between September and December 2014. Data were collected on the company (characterization and information regarding the program’s desired results) and workers (personal and professional information, anthropometrics, health, lifestyle and food consumed the previous day). Population estimates were calculated for RN on the characteristics of workers and the study variables. The main variable was BMI. The secondary variables were waist circumference (WC), nutritional diagnosis, calorie intake, blood pressure, metabolic variables and lifestyle indicators. The statistical method used was hierarchical mixed effects linear regression for interval variables and hierarchical mixed effects logistic regression for binary variables. The variables measured in ordinal scales were analyzed by ordinal logistic regression adjusted for correlated variables, adopting robust standard errors. The results for interval variables are presented as point estimates and their 95% confidence intervals; and as odds-ratios and their 95% confidence intervals for binary variables. The Fisher’s exact and Student’s t-tests were used for simple comparisons between proportions and means, respectively. Differences were considered statistically significant at p<0.05. A total of 1069 workers were interviewed, of which 541 were from the WFP group and 528 from the Non WFP group. Subjects were predominantly males and average age was 34.5 years. Significant intergroup differences were observed for schooling level, income above 1 MW (minimum wage) and specific training for their position at the company. The results indicated a significant difference between the BMI of workers benefitted, which was on average 0.989 kg/m2 higher than the BMI of workers from the Non WFP group (p=0.002); and between the WC, with the waist circumference of WFP group workers an average of 1.528 cm larger (p<0.05). Higher prevalence of overweight and obesity (p<0.001) and cardiovascular risk (p=0.038) were recorded in the WFP group. Tests on the possible effect of the WFP on health (blood pressure and metabolic indicators) and lifestyle indicators (smoking, alcohol consumption and exercise) were not significant. With respect to worker’s diets, differences were significant for consumption of saturated fat (lunch and daily intake), salt (lunch, other meals and daily intake) and proteins (other meals and daily intake), with higher consumption of these nutrients in the WFP group. The study showed a possible positive impact of the WFP on nutritional status (BMI and WC) among the workers benefitted. No possible effects of the program were observed for the lifestyle indicators studied. Workers benefitted consumed less salt, saturated fat and protein. The relevance of the WFP is recognized for this portion of society and it is understood that, if the program can reach and impact those involved, the development of educational initiatives aimed at nutritional and food safety may also exert a positive influence.

Quedas em idosos assistidos na estratégia saúde da família: frequência e fatores associados

The growth of the elderly population is a global phenomenon and, in Brazil, this transformation is happening in a very rapid rhythm. With the current population aging, this emerging age group will need more health care and attention. One of the characteristics of the population aging is the progressive accumulation of disabilities, which makes it more vulnerable to falls. This study was developed with the purpose of knowing the episode falls in the scope of an elderly population treated at a Family Health Unit. It is a research with cross-sectional nature, and its sample was composed by 121 elderly. The research was approved by the Ethics Committee of HUOL, with Opinion nº 816.022. We applied a questionnaire to the participants, and the results were statistically analyzed by using Chi-square test and Fisher’s exact test to verify the association between variables. In order to perform a multivariate analysis, we used the method of the Binomial Logistic Regression. For both tests, we accepted significance p<0,05 and CI of 95%. The results prove that the majority belongs to the female gender (76,9%); the age group of elderly reaches 88,4% and 11,6% is over-aged; regarding the marital status, 35,3% are married and 29,4% widowed; 92,1% with family income between one and two minimum wages; and 91,8% live with their partners and/or children. Regarding the frequency of falls, we found that 61,2% of the surveyed elderly suffered one or more falls in 2014. As associated factors, it became clear that 73,8% were due to extrinsic factors, 6,4% to intrinsic factors and 21,4% to both factors. As a consequence of the fall, we found that 89,2% have fear of falling again, 37,3% showed anxiety and 13,3% had their ambulation affected. Concerning the exposure to the risk factors, the most prevalent places were: street/avenue (31,0%), pavement (19,0%), living room (14,3%) and courtyard/backyard (10,7%). The study has proven a statistically significant association among female gender (p=0,001), rubble/objects in the backyard (p=0,015) and furniture that may cause accidents (p=0,005). It was evident among the elderly people surveyed, 72.7% receive little information about falls, being a risk factor for falls. We conclude that there is a high frequency of falls in the surveyed elderly, thereby constituting a worrisome data because this event in the elderly population is a serious matter, which raises the need to ensure them a safe environment in their homes and, above all, outside them. The information provided by the Family Health Strategy team are important to avoid these occurrences, which reinforces the need for developing health education activities together with the population as a way to prevent and reduce the occurrence of falls, thereby improving the quality of life of elderly.

Imunoexpressão das proteínas APE-1 e XRCC-1 em carcinoma epidermoide de língua oral

DNA repair systems play a critical role in protecting the human genome from damage caused by carcinogens present in the environment. Mutations in DNA repair genes may be responsible for tumor development and resistance of malignant cells to chemotherapeutic agents. The major pathway for oxidative DNA damage repair is the base excision repair pathway. The objective of this study was to investigate the immunoexpression of APE-1 and XRCC-1, which are proteins involved in DNA base excision repair and its association with clinical and histopathological parameters in oral tongue squamous cell carcinoma (OTSCC), in order to investigate a possible prognostic value for those proteins. The expression of APE-1 and XRCC-1 was evaluated semi-quantitatively by immunohistochemistry in 50 OTSCC cases. Clinical data was collected from patients’ medical charts and histopathological grading was performed for each case. Statistical analysis (Chi-square and Fisher’s exact tests; significance of 5%) was performed to determine the association between protein expressions and clinico-pathological characteristics. APE-1 was highly expressed in nucleus and cytoplasm in 56% of cases. XRCC-1 showed overexpression only in nucleus in 60% of cases. High expression of XRCC-1 was significantly associated to clinical stages I and II (P=0.02). Both proteins were not associated to other clinical parameters or histopathological grading. Our findings demonstrate that DNA base excision repair proteins APE-1 and XRCC-1 are upregulated in OTSCC, however, they are not related to clinical and histologic parameters, except for XRCC-1 association to better clinical staging. Our results indicate that the immunohistochemical expression of these proteins has no association with prognostic parameters in this tumor.
