The participation of the nutritionist in Primary Health Care in a large urban center

Nutritionists are important professionals for ensuring the implementation of health promotion, treatment and rehabilitation. However, their participation in primary healthcare from a quantitative standpoint is limited. The city of Sao Paulo has experienced an uneven urbanization process triggering new problems of insecurity in terms of food and nutrition. This article analyzes the performance of the primary healthcare nutritionist in a large urban center. It is a quantitative study that used data from the Municipal Health Department, population data of Sao Paulo and a semi-structured questionnaire applied in individual interviews. All regions of the city are found to have fewer nutritionists than the recommendation of the Federal Council of Nutritionists. There are 123 nutritionists in the basic healthcare network and 51 in the Family Health Support Nuclei (FHSN) (57.3%). Each nutritionist from the FHSN accompanies 7.1 family health strategy teams on average. The age groups corresponding to children are less frequently seen by nutritionists. Comparing the activities, the transition from a model of primary health care focused on individual care to a model that prioritizes group care was observed.

Emissions generated by sugarcane burning promote genotoxicity in rural workers: a case study in Barretos, Brazil

Abstract Background To determine the possible genotoxic effect of exposure to the smoke generated by biomass burning on workers involved in manual sugar cane harvesting. Methods The frequency of micronuclei in exfoliated buccal cells and peripheral blood lymphocytes was determined in sugarcane workers in the Barretos region of Brazil, during the harvest season and compared to a control population, comprised of administrative employees of Barretos Cancer Hospital. Results The frequency of micronuclei was higher in the sugar cane workers. The mean frequency in blood lymphocytes (micronuclei/1000 cells) in the test group was 8.22 versus 1.27 in the control group. The same effect was observed when exfoliated buccal cells were considered (22.75 and 9.70 micronuclei/1000 cells for sugar cane workers and controls, respectively). Conclusion Exposure to emissions produced by the burning of sugar cane during harvesting induces genomic instability in workers, indicating the necessity of adopting more advanced techniques of harvesting sugar cane to preserve human health.

Bridging innovation, nature and tradition: assessment of strategies for rural tourism development in Maramureş (Romania)

In the frame of EU rural policy, always more oriented towards environmental concerns and green livelihoods, Romania stands out for the predominance of rural areas and high nature value farming. The country has to face the challenge of joining the modernization process of rural farming systems with the valorization of local assets. Tourism has emerged as one of the main drivers of change and contributors for a sustainable exploitation of local resources. Rural tourism (RT) can foster the enhancement of the territorial capital (TC), the preservation of public goods (PGs) and the promotion of a more environmental oriented livelihood. The research focuses on a case study area, two valleys from Maramureş, where environmental approaches as diversification strategies are partially explored. The work investigates the role of tourism initiatives for the promotion of green oriented practices. The first part of the work is based on a literature review and interdisciplinary analysis of secondary data to identify the key issues: from rural development policy, to the concept of TC, of PGs and RT. The Romanian development programmes and related strategies are investigated; afterwards the characteristics of the County and the role of RT as diversification and valorisation policies is considered. The second part is based on the collection of primary data through interviews to different local stakeholders (farmers owners of rural guesthouses, local administrators, networks and artisans). The main frequencies are analyzed, a cluster analysis is computed to evaluate the similarities within the most representative groups and a comparative analysis is carried out between the two Valleys. The frame of the analysis is based on a set of indicators following the dimensions of the TC, to assess the characteristics of the local stakeholders and to outline the perception about the local PGs and on the adopted strategies to manage the territory. Final considerations are elaborated and few scenarios are outlined, giving relevance to the importance of improving awareness and creating embeddedness among public-private local stakeholders and resources as a tool for a socio-economic and environmental development of the area.

Linking rural tourism to agriculture. Evidences from comparative case studies in Kosovo, Italy and Spain

Rural tourism has been widely promoted in the European Union as an effective measure counteracting economic and social challenges facing rural areas especially those with declining agriculture economies. Particularly its role is seen in provision and maintenance of public goods which are more and more demanded by the public and considered in the policymaking. In Kosovo, rural tourism has been developed through the support of the international organizations and private sector initiatives, with primary aim to generate additional income for rural households and sustainable management of natural and cultural resources. Anyhow, it could be stated that the use of territorial capital to enhance the quality of the tourist offer and undertake promotion at wider circles of people has not been well explored so far, particularly possible links with agriculture that would satisfy visitors demand. In this regard this research study analyzes involvement of local stakeholders and use of territorial capital to develop tourist offer in rural areas of Kosovo. Beside, study applies comparative approach with other two areas of the European Union, Appennino Bolognese in Italy and Alpujara in Spain, to understand and compare the process of rural tourism development and demand characteristics between Kosovo and these areas. A survey has been conducted in all three study areas with rural tourism visitors to understand their preferences for public and private goods and services when visiting rural areas and the role of agriculture in sustaining rural tourism. Results show that there is a potential to link rural tourism with agriculture in Kosovo, which would help in sustaining agriculture and add additional value to local food products, which in return would enhance the tourist offer and make it more attractive for the visitors but also for the farmers as an additional revenue generating sector.

Connecting the Dots: Families and Children with Special Needs in a Rural Community

Due to the rising number of children with disabilities, the needs of these families must be addressed. This article describes the development and implementation of a regional forum in a rural community to address education and training needs of families and professionals. The Special Needs Summit provided workshops, information, and activities for parents and professionals. Participants were invited to participate in a study through a survey soliciting feedback regarding the importance and effectiveness of the training and information received through the Summit, gaps in resources, and future educational and training needs. Overall, participants gave satisfactory ratings regarding the training and education provided during the forum, and gave direction for future programming.

Commentary on “Connecting the Dots: Families and Children with Special Needs in a Rural Community”

Starks et al. discuss an evaluation of educational initiatives to improve rural systems of care for children with special needs. Akin to the medical home neighborhood concept, building a holistic medical "village" entails improving collaboration, sharing accountability, and helping families to navigate the health care system. The article suggests that policymakers should include patient experiences of care in program evaluation, and they should build a community infrastructure for shared information and efficient communication.

Coordination of Family Preservation Services in a Rural Community: A Case Study

Family preservation programs designed to prevent the out-of-home placement of children depend on the coordination of services from multiple agencies. Little is known regarding how coordination occurs. This case study examined this issue. Information was sought from all workers who provided services to each of five families and 'from families' case records. Thirty-one workers were interviewed with a semi-structured interview schedule containing rating scales and questions with open-ended response formats. Case records were reviewed with a case record review form. Analyses of data revealed the following. Services were coordinated to a moderate degree but that coordination deteriorated over time. Workers elaborated how aspects of communities, human service agencies, workers, and families affected coordination. Implications of findings for future research were drawn.

Mechanistic studies of mouse skin tumor promotion by chrysarobin

Since the anthrone chrysarobin oxidizes and generates free radicals, investigations were conducted to assess a possible role for free radicals or reactive oxygen species (ROS) in skin tumor promotion by chrysarobin. Epidermal glutathione levels were not noticeably altered by chrysarobin, nor did a glutathione-depleting agent enhance promotion by chrysarobin. Multiple applications of chrysarobin increased lipid peroxide levels in mouse epidermis two-fold as compared with controls. The antioxidant $\alpha$-tocopherol and the lipoxygenase inhibitor nordihydroguaiaretic acid both inhibited production of lipid peroxides by chrysarobin. The antioxidants $\alpha$-tocopherol acetate and ascorbyl palmitate effectively inhibited promotion and promoter-related effects induced by chrysarobin. Since prooxidant states can lead to increases in intracellular Ca$\sp{2+}$, the effect of two Ca$\sp{2+}$ antagonists, verapamil and TMB-8, on chrysarobin-induced promotion and promoter-related effects were investigated. Both Ca$\sp{2+}$ antagonists inhibited promotion and promoter-related effects induced by chrysarobin, suggesting a possible role for intracellular Ca$\sp{2+}$ alterations in chrysarobin-tumor promotion. Since radical generating compounds are reported to possess the ability to enhance progression of papillomas to squamous cell carcinomas (SCCs), the effects of chrysarobin on papilloma development were tested. Growth kinetics and regression of papillomas generated with limited promotion with chrysarobin were similar to what was reported for the nonradical generating promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) (Aldaz et al., 1991). To test the chrysarobin's ability to enhance progression of pre-existing papillomas to SCCs, tumors were generated by initiation with dimethylbenz (a) anthracene and promotion with TPA. Then mice were treated with chrysarobin, TPA or acetone for 45 weeks. When mice treated with chrysarobin were compared to mice treated continually with TPA with similar numbers of papillomas, the number of papillomas that progressed to SCCs was similar, suggesting that papilloma burden influences the progression of papillomas to SCCs, rather than radical production. In summary, the present study suggests that chrysarobin produces oxidative stress in mouse epidermis as indicated by the generation of lipid peroxides. Antioxidants inhibited production of lipid peroxides and tumor promotion by chrysarobin. Collectively, these data suggest a role for free radicals or ROS in tumor promotion by chrysarobin. ^

Presence of three pesticides in rural drinking water sources in Kenya

A cross-sectional study on the use of three pesticides and their presence in drinking water sources was conducted in Githunguri/Kiaria community between January 1994-March 1995. The main objective of the study was to determine the extent to which some of the pesticides used by the Githunguri/Kiaria agricultural community were polluting their drinking water sources. Due to monetary and physical limitations, only DDT, its isomers and metabolites, carbofuran and carbaryl pesticides were identified and used as surrogates of pollution for the other pesticides.^ The study area was divided into high and low lying geographic surface areas. Thirty-four and 38 water sampling sites were randomly selected respectively. During wet and dry seasons, a total of 144 water samples were collected and analyzed at the Kenya Bureau of Standards Laboratory in Nairobi. Gas chromatography was used to analyze samples for possible presence of DDT, its isomers and metabolites, while high pressure liquid chromatography was used to analyze samples for carbofuran and carbaryl pesticides.^ Six sites testing positively for DDT, its isomers and metabolites represented 19.4% of the total sampled sites, with a mean concentration of 0.00310 ppb in the dry season and 0.0130 ppb in the wet season. All the six sites testing positively for the same pesticide exceeded the European maximum contaminant limit (MCL) in the wet season, and only one site exceeded the European MCL in the dry season.^ Those sites testing positively for carbofuran and carbaryl represented 5.6% of the total sampled sites. The mean concentration for the carbofuran at the sites was 2.500 ppb and 1.590 ppb in the dry and wet seasons respectively. Similarly, the mean concentration for carbaryl at the sites was 0.281 ppb in the dry season and 0.326 ppb in the wet season.^ One site testing positively for carbofuran exceeded the European MCL and WHO set limit in the wet season, while one site testing positively for the same pesticide exceeded the USA, Canada, European and WHO MCLs in the dry season. Similarly, one site which tested positively for carbaryl pesticide exceeded the European MCL in both seasons.^ Out of the 2,587 community members in the study area, 333 (13%) were exposed through their drinking water sources to the three pesticides investigated by this study. As a public health measure, integrated pest management approaches (IPM), protection of the wells and education of the community is necessary to minimize the pollution of the environment and safeguard the drinking water sources from pollution by the pesticides. ^

The door of the tomb is open: Participatory action research to assess the impact of strengthened community capacity on maternal health care in rural Mali

This participatory action-research project addressed the hypothesis that strengthened community and women's capacity for self-development will lead to action to address maternal health problems and the prevention of maternal morbidity and mortality in Mali. Research objectives were: (1) to undertake a comparative cross-sectional study of the association of community capacity with improved maternal health in rural areas of Sanando, Mali, where capacity building interventions have taken place in some villages but not in others. (2) to describe women's maternal health status, access to and use of maternal health services given their residence in program or comparison communities.^ The participatory action research project was an integrated qualitative and quantitative study using participatory rural appraisal exercises, semi-structured group interviews and a cross-sectional survey.^ Factors related to community capacity for self-development were identified: community harmony; an understanding of the benefits of self-development; dynamic leadership; and a structure to implement collective activities.^ A distinct difference between the program and comparison villages was the commitment to train and support traditional birth attendants (TBAs). The TBAs in the program villages work in the context of the wider, integrated self-development program and, 10 years after their initial training, the TBAs continue to practice.^ Many women experience labor and childbirth alone or are attended by an untrained relative in both program and comparison villages. Nevertheless a significant change is apparent, with more women in program villages than in comparison villages being assisted by the TBAs. The delivery practices of the TBAs reveal the positive impact of their training in the "three cleans" (clean hands of the assistant, clean delivery surface and clean cord-cutting). The findings of this study indicate a significant level of unmet need for child spacing methods in all villages.^ The training and support of TBAs in the program villages yielded significant improvements in their delivery practices, and resulting outcomes for women and infants. However, potential exists for further community action. Capacities for self-development have not yet been directed toward an action plan encompassing other Safe Motherhood interventions, including access to family planning services and emergency obstetric care services. ^

Cultural beliefs and hypertension in rural Philippines

Hypertension (HTN), the major risk factor for cardiovascular disease (CVD), is emerging as a major public health problem in the Philippines. CVD has been the leading cause of mortality in the Philippines since 1990. ^ Although research has shown that certain populations have a greater propensity for HTN, and that culture may be a factor, empirical investigations of the influence of cultural beliefs on HTN are lacking. ^ The operational aims of this study were to: (a) develop and examine the reliability (test-retest, internal consistency) and validity (content) of a questionnaire which measures factors related to HTN; (b) administer the questionnaire; and (c) measure blood pressure, height, and weight of the ≥ 30 year old residents of San Antonio, Nueva Ecija, Philippines. ^ The analytic aims were to determine the: (a) cultural beliefs relating to HTN; (b) associations between cultural beliefs and HTN; and (c) extent to which cultural beliefs versus biological, behavioral, socioeconomic, and access factors are associated with HTN. ^ A cluster survey was conducted among 336 residents ≥ 30 years old in May, 1998. Sixty clusters of households were derived using probability proportionate to size sampling technique. Seven households per cluster were visited and one respondent per household was randomly chosen for interview and measurement of blood pressure, height and weight. A response rate of 84% (336/400) was achieved. ^ Results showed that the test-retest reliability of cultural belief items was 0.69–0.96. Internal consistency reliability was 0.74. ^ HTN (SBP ≥ 140; or DBP ≥ 90 mmHg; or currently taking anti-hypertensive medication) prevalence was 23/100. Univariate logistic regression showed cultural beliefs to be significantly associated (p < 0.037) with HTN. However, multivariate analysis showed that only age ≥ 50 (p = 0.000), family history of HTN (p = 0.004) and body mass index ≥ 25 (p = 0.003) were significant predictors. ^ In the absence of fully implemented programs to prevent and control HTN, the current prevalence is only expected to increase, leading to substantial increases in morbidity and mortality and health care cost. It is recommended that research which focuses on designing, implementing, and evaluating culturally appropriate community-wide programs on HTN prevention and control be undertaken in this community. ^

Understanding the underlying mechanisms of recent Jatropha curcas L. adoption by smallholders in Kenya: A rural livelihood assessment in Bondo, Kibwezi, and Kwale districts

Between 2004 and 2007, NGOs, community based organisations and private investors promoted jatropha in Kenya with the aim of generating additional income and producing biofuel for rural development. By 2008 it became gradually evident that jatropha plantations (both mono- and intercropping) are uneconomical and risky due to competition for land and labour with food crops. Cultivation of jatropha hedges was found to have better chances of economic success and to present only little risks for the adopting farmers. Still, after 2008 a number of farmers went on adopting jatropha in plots rather than as hedges. It is hypothesised that lack of awareness about the low economic prospects of jatropha plantations was the main reason for continued adoption, and that smallholder farmers with higher resource endowments mainly ventured into its cultivation. In this study we provide an empirical basis for understanding the role of households' capital assets in taking up new livelihood strategies by smallholder farmers in three rural districts in Kenya. For that purpose, we assess the motivation and enabling factors that led to the adoption of jatropha as a new livelihood strategy, as well as the context in which promotion and adoption took place. A household survey was conducted in 2010, using a structured questionnaire, to collect information on household characteristics and capital asset endowment. Data were analysed using descriptive statistics and non-parametric statistical tests. We established that access to additional income and own energy supply were the main motivation for adoption of jatropha, and that financial capital assets do not necessarily have a positive influence on adoption as hypothesised. Further, we found that the main challenges that adopting farmers faced were lack of access to information on good management practices and lack of a reliable market. We conclude that continued adoption of on-farm jatropha after 2008 is a result of lacking awareness about the low economic value of this production type. We recommend abandoning on-farm production of jatropha until improved seed material and locally adapted agronomic knowledge about jatropha cultivation becomes available and its production becomes economically competitive.
