    Background: Peru is experiencing a stage of nutritional transition where the principal characteristics are typical of countries undergoing development. Objectives: The objectives of this study were the following: (a) compare physical growth patterns with an international standard; (b) determine biological age; and (c) analyze the double nutritional burden of adolescents living at a moderate altitude in Peru. Design: Weight, standing height, and sitting height were measured in 551 adolescents of both sexes (12.0 to 17.9 years old) from an urban area of Arequipa, Peru (2328 m). Physical growth was compared with the international standard of the CDC-2000. Biological age was determined by using a non-invasive transversal technique based on years from age at peak height velocity (APHV). Nutritional state was determined by means of weight for age and height for age. Z scores were calculated using international standards from the CDC-2000. Results: Body weight for both sexes was similar to the CDC-2000 international standards. At all ages, the girls’ height (p < 0.05) was below the standards. However, the boys’ height (p < 0.05) was less at ages, 15, 16, and 17. Biological age showed up in girls at age 12.7 years and for boys at 15.2 years. Stunted growth (8.7% boys and 18.0% girls) and over weight (11.3% boys and 8.8% girls) occurred in both groups. A relationship existed in both sexes between the categories of weight for the age and stunted growth by sex. Conclusions: Adolescents living at a moderate altitude exhibited stunted linear growth and biological maturation. Furthermore, adolescents of both sexes showed the presence of the double nutritional burden (stunted growth and excessive weight). PMID:26404334

    Titi monkeys (genus Callicebus) are small-bodied platyrrhines that supplement their predominantly frugivorous diet with variable amounts of leaves, seeds, and/or arthropod prey. Notable interspecific variation in the amount of insect prey in the diet has been observed in Callicebus, ranging from 0% to 20%. In this study, I investigate the degree and type of prey foraging in a little-known species, Callicebus oenanthe inhabiting a fragmented, secondary forest on the foothills of the Andes in northern Peru. I present data on prey type, prey search and capture techniques, substrate/vegetation use, foraging height, prey capture efficiency, and seasonal variation of insect prey foraging in one group of C. oenanthe observed from January to August 2005. Insect prey accounted for 22% of the diet, the highest amount reported for any Callicebus species to date, and insects from at least six different orders were included. C. oenanthe was mainly an investigative forager of hidden prey, manipulating easy-to-open substrates such as rolled up leaves, and hunted ant swarms and larger insects opportunistically. Insect foraging was predominant during the dry season (26%) and decreased during the wet season (13%). The study group foraged mostly in the understory (2-6 m) within vine-laden shrubs and trees, which may conform to an anti-predator strategy of crypticity. Overall the group had an 83% insect capture success rate. These data suggest that insect prey is an important part of the diet of C. oenanthe and may be especially notable during periods of resource scarcity. This study adds to the knowledge concerning insect prey foraging in Callicebus, which can have an important role in defining ecological strategies in the selection of secondary protein food resources within a given ecosystem.

    Background Rapid urbanization, increase in food availability, and changes in diet and lifestyle patterns have been changing nutritional profiles in developing nations. We aimed to describe nutritional changes in children under 5 years and women of reproductive age in Peru, during a 15-year period of rapid economic development and social policy enhancement. Materials and Methods Trend analyses of anthropometric measures in children of preschool age and women between 15–49 years, using the Peruvian National Demographic and Family Health Surveys (DHS) from 1996 to 2011. WHO growth curves were used to define stunting, underweight, wasting and overweight in children <5y. We employed the WHO BMI-age standardized curves for teenagers between 15–19y. In women >19 years, body mass index (BMI) was analyzed both categorically and as a continuous variable. To statistically analyze the trends, we used regression models: Linear and Poisson for continuous and binary outcomes, respectively. Results We analyzed data from 123 642 women and 64 135 children, from 1996 to 2011. Decreases over time were evidenced for underweight (p<0.001), wasting (p<0.001), and stunting (p<0.001) in children under 5y. This effect was particularly noted in urban settings. Overweight levels in children reduced (p<0.001), however this reduction stopped, in urban settings, since 2005 (∼12%). Anemia decreased in children and women (p<0.001); with higher reduction in urban (↓43%) than in rural children (↓24%). BMI in women aged 15–19 years increased (p<0.001) across time, with noticeable BMI-curve shift in women older than 30 years. Moreover, obesity doubled during this period in women more than 19y. Conclusion Nutrition transition in Peru shows different patterns for urban and rural populations. Public policies should emphasize targeting both malnutrition conditions—undernutrition/stunting, overweight/obesity and anemia—considering age and place of residence in rapid developing societies

    Millions of people in Asia are facing challenges from undernutrition, obesity, and diet-related non-communicable diseases. Unilever, as a global food business, has a simple approach to nutrition strategy: 'better products' help people to enjoy 'better diets' and live 'better lives.' For 'Better Products,' Unilever strives to improve the taste and nutritional qualities of all our products. By 2020, we commit to double the proportion of our entire global portfolio meeting the highest nutrition standards, based on globally recognised dietary guidelines. Unilever sets a clear plan to achieve reduction of sodium, saturated fat, trans fat, sugar, and calories in our products. Unilever developed fortified seasoning and spread products in 2013 for Vietnam, Indonesia, and the Philippines in collaboration with government bodies to address nutrient deficiencies. For 'Better Diets and Better Lives,' Unilever uses targeted communication to raise awareness and promote behavior change for healthy lifestyles. We committed to full nutrition labeling on our food products by 2015. We contribute experience to science-based regional initiatives on product labeling as well as nutrient profiling. Unilever collaborated with international, regional and country bodies to promote consumer understanding and food accessibility on public health priorities such as proper salt consumption, healthier meals, and employee well-being programs. Looking ahead, we are continuing to improve the nutritional profile of our products as well as our communication to improve diets and lives. Collaboration between industry, government and public health organizations is needed to address complex diet and life style issues.

    Irritable bowel syndrome is a complex disorder whose pathophysiology involves alterations in the enteric microbiota, visceral hypersensitivity, gut immune/barrier function, hypothalamic-pituitary-adrenal axis regulation, neurotransmitters, stress response, psychological factors, and more. The importance of diet in the management of irritable bowel syndrome has taken center stage in recent times as the literature validates the relationship of certain foods with the provocation of symptoms. Likewise, a number of elimination dietary programs have been successful in alleviating irritable bowel syndrome symptoms. Knowledge of the dietary management strategies for irritable bowel syndrome will help guide nutritionists and healthcare practitioners to deliver optimal outcomes. This tutorial reviews the nutrition management strategies for irritable bowel syndrome.

    Formative research is critical for developing effective nutrition-specific interventions to improve infant and young child (IYC) feeding practices and promote healthy growth. Health workers interact with caregivers during health facility visits, yet there is limited research about how to optimize delivery of such interventions during these visits. The extensive reach of IYC health services globally calls for research to address this gap. In Trujillo, Peru, formative research was conducted to explore complementary feeding practices with caregivers as well as health worker routines and interactions with caregivers related to feeding and healthy growth; results informed the development and delivery of an educational intervention. Multiple qualitative methods were used to collect data on a purposive sample of health workers and caregivers from three health facilities and communities: household trials followed. Complementary feeding messages with doable behaviours were developed, and three were selected as key to promote based on their nutritional impact and cultural acceptability. In the health facilities, medical consultation, well-child visits and nutrition consultation all dealt with aspects of IYC nutrition/growth during their interactions with caregivers but were independent and inconsistent in approach. A nutrition education strategy was developed based on consistency, quality and coverage in the IYC health services. We conclude that formative research undertaken in the community and IYC health services was critical to developing a successful and culturally relevant intervention to promote optimal complementary feeding practices and healthy growth during interactions between health workers and caregivers at routine health facility visits. © 2016 John Wiley & Sons Ltd.

    We analyzed and compared two Integrated Management Strategies for Dengue Prevention and Control (IMS-dengue Colombia and IMS-dengue Peru), through a narrative review of available literature, in order to identify common and dissimilar patterns in two Andean countries with epidemiological differences in the context of dengue disease. We were able to identify differences related to: formal assessment of problem, formation of groups of actors, and quantitative information provided by performance indicators. These limitations identified in IMS-dengue Colombia 2006-2010 were overcome in a new version of the strategy (IMS-dengue Colombia 2012-2021). We were able to document an epidemiological impact of implementation of IMS-dengue Colombia 2006-2010. Additionally, a gradual increase was observed in incidence rates of dengue cases that could be related to the strengthening of surveillance system of IMS- dengue Peru.

    To provide novel information on psittacine diets, we analyzed the texture, crude protein, crude fat, Ca, P (total), Mg, K, Na, S, Cu, Fe, and Zn concentrations of crop contents from 10 free-living scarlet macaw (Ara macao) chicks from lowland forests of southeastern Peru. We compared our results with nutrient concentrations of known wild parrot foods and published psittacine dietary recommendations to highlight similarities and differences and suggest future avenues of research. The diets were much coarser textured than those recommended for hand feeding. Soil in the diet provided an important source of Na, but Na levels were still lower than all recommendations. Concentrations of protein, Zn, K, Cu, and P (total) were near to or within the range of recommendations for captive psittacine birds. Fat, Ca, and Mg concentrations were greater in crop contents than in the average food plants and greater than published recommendations. The Na:K ratios were only one-twentieth of those recommended for young poultry. Future analyses should investigate the bioavailability of Fe, Ca, and Zn in these diets and the effects of varying concentrations of fat, Na, Ca, Mg, and Na:K ratio on psittacine growth and development.

    The objective of this study was to test the hypothesis that cooperative learning strategies will help to increase nutrition knowledge of nurses and nursing assistants caring for the elderly in different institutional communities of the Basque Country, Spain. The target population was a sample of volunteers, 16 nurses and 28 nursing assistants. Training consisted of 12 nutrition education sessions using cooperative strategies conducted over a period of 3 consecutive weeks. The assessment instruments included two pretest and two posttest questionnaires with questions selected in multiple-choice format. The first questionnaire was about general knowledge of applied nutrition (0-88 point scale) and the second one on geriatric nutrition knowledge (0-18 point scale). Data were analyzed using SPSS vs. 11.0. The outcomes indicated a significant increase in general nutrition knowledge (difference between the pre- and post-test mean score: 14.5+/-10.1; P<0.001) and in geriatric nutrition knowledge for all participants (difference between the pre- and post-test mean score: 4.6+/-4.6; P<0.001). So the results indicated that cooperative learning strategies could improve the nutrition knowledge of nursing staff. Additionally, the results of this study provide direction to continuing nutrition education program planners regarding appropriate content and methodology for programs.

    Background The population of Portugal is aging. The lack of data on older adults’ nutritional status and the lack of nutrition knowledge amongst health professionals, caregivers, and older adults themselves, remains a challenge. Objective The Nutrition UP 65 study aims to reduce nutritional inequalities in the older Portuguese adult population and improve knowledge regarding older Portuguese adults’ nutritional status, specifically relating to undernutrition, obesity, sarcopenia, frailty, hydration, sodium, and vitamin D statuses. Methods A representative sample of older Portuguese adults was selected. Sociodemographic, lifestyle, anthropometric, functional, and clinical data were collected. Sodium excretion, hydration, and vitamin D statuses were assessed. Results Data collection (n=1500) took place between December, 2015 and June, 2016. Results will be disseminated in national and international scientific journals, and via Portuguese media. Conclusions Nutrition UP 65 results will provide evidence for the design and implementation of effective preventive public health strategies regarding the elderly. These insights may represent relevant health gains and costs savings. PMID:27628097

  15. Nutritional strategies to optimize dairy cattle immunity.

    2016-06-01

    Dairy cattle are susceptible to increased incidence and severity of both metabolic and infectious diseases during the periparturient period. A major contributing factor to increased health disorders is alterations in bovine immune mechanisms. Indeed, uncontrolled inflammation is a major contributing factor and a common link among several economically important infectious and metabolic diseases including mastitis, retained placenta, metritis, displaced abomasum, and ketosis. The nutritional status of dairy cows and the metabolism of specific nutrients are critical regulators of immune cell function. There is now a greater appreciation that certain mediators of the immune system can have a reciprocal effect on the metabolism of nutrients. Thus, any disturbances in nutritional or immunological homeostasis can provide deleterious feedback loops that can further enhance health disorders, increase production losses, and decrease the availability of safe and nutritious dairy foods for a growing global population. This review will discuss the complex interactions between nutrient metabolism and immune functions in periparturient dairy cattle. Details of how either deficiencies or overexposure to macro- and micronutrients can contribute to immune dysfunction and the subsequent development of health disorders will be presented. Specifically, the ways in which altered nutrient metabolism and oxidative stress can interact to compromise the immune system in transition cows will be discussed. A better understanding of the linkages between nutrition and immunity may facilitate the design of nutritional regimens that will reduce disease susceptibility in early lactation cows.

    Background Chagas disease is endemic in the rural areas of southern Peru and a growing urban problem in the regional capital of Arequipa, population ∼860,000. It is unclear how to implement cost-effective screening programs across a large urban and periurban environment. Methods We compared four alternative screening strategies in 18 periurban communities, testing individuals in houses with 1) infected vectors; 2) high vector densities; 3) low vector densities; and 4) no vectors. Vector data were obtained from routine Ministry of Health insecticide application campaigns. We performed ring case detection (radius of 15 m) around seropositive individuals, and collected data on costs of implementation for each strategy. Results Infection was detected in 21 of 923 (2.28%) participants. Cases had lived more time on average in rural places than non-cases (7.20 years versus 3.31 years, respectively). Significant risk factors on univariate logistic regression for infection were age (OR 1.02; p = 0.041), time lived in a rural location (OR 1.04; p = 0.022), and time lived in an infested area (OR 1.04; p = 0.008). No multivariate model with these variables fit the data better than a simple model including only the time lived in an area with triatomine bugs. There was no significant difference in prevalence across the screening strategies; however a self-assessment of disease risk may have biased participation, inflating prevalence among residents of houses where no infestation was detected. Testing houses with infected-vectors was least expensive. Ring case detection yielded four secondary cases in only one community, possibly due to vector-borne transmission in this community, apparently absent in the others. Conclusions Targeted screening for urban Chagas disease is promising in areas with ongoing vector-borne transmission; however, these pockets of epidemic transmission remain difficult to detect a priori. The flexibility to adapt to the epidemiology that

    This review focuses on evidence-informed strategies to enhance learning in undergraduate nutrition education. Here, we describe the general shift in undergraduate education from a teacher-centered model of teaching to a student-centered model and present approaches that have been proposed to address the challenges associated with this shift. We further discuss case-based, project-based, and community-based learning, patient simulation, and virtual clinical trials as educational strategies to improve students' critical thinking and problem-solving skills; these strategies are well suited to the teaching of undergraduate nutrition. The strategies are defined, and we discuss the potential benefits to students and how they can be applied specifically to the teaching of undergraduate nutrition. Finally, we provide a critical analysis of the limitations associated with these techniques and propose several directions for future research, including research methodologies that may best evaluate teaching strategies in terms of both teaching and learning outcomes. Consideration of these evidence-informed strategies is warranted, given their ability to encourage students to develop relevant skills that will facilitate their transition beyond the university classroom.

    Healthy eating is a prominent concern amongst public health and diet professionals. Public understanding of healthy eating presents a topic of interest in understanding scientific credibility in the public domain. Three prominent Dutch nutrition scientists, Kok, Seidell and Katan, have produced popular science books on healthy eating, aiming to remove myths about food and nutrition from the public domain. I describe how they do so, and which strategies they have chosen to achieve this goal. In their books, they move beyond traditional academic strategies to build credibility and devise credibilising strategies resembling those of diet authors. While doing so, they move beyond the deficit model, but end up competing for dietary credibility on the diet authors' terms.

    As part of a larger research program evaluating chemical threshold levels for a Push-Pull intervention to reduce man-vector (Aedes aegypti) contact, this qualitative study explored local perceptions and strategies associated with mosquito control within dengue-endemic communities in Peru and Thailand. Focus groups were used to provide preliminary information that would identify possible public acceptance issues to the Push-Pull strategy in each site. Nine focus group discussions (total of 102 individuals) conducted between September 2008 and March 2009 examined several themes: 1) current mosquito control practices; 2) perceptions of spatial repellency and contact irritancy versus killing mosquitoes; and 3) initial perceptions toward mosquito host-seeking traps. Results indicate participants use household-level strategies for insect control that reveal familiarity with the concept of spatial repellent and contact irritant actions of chemicals and that placing traps in the peridomestic environment to remove repelled mosquitoes was acceptable. Preliminary evidence suggests a Push-Pull strategy should be well accepted in these locations. These results will be beneficial for developing future large scale push-pull interventions and are currently being used to guide insecticide application strategies in (entomological) proof-of-concept studies using experimental huts.

    Three new specimens of the walrus-like dolphin Odobenocetops from the Pliocene of Peru, shed new light on the anatomy and adaptive strategies of this unique Cetacean. Odobenocetops leptodon nov. sp. is represented by a skull, which bears a 1 35-cm-long needle-like right tusk and a small 25-cm-long left tusk the apex of which was erupted. The long tusk was probably held almost parallel to the axis of the body when swimming. In contrast to O. peruvianus, O. leptodon probably had a small melon and, therefore, echolocation ability, but had reduced (or no) binocular vision. A skull of O. peruvianus with two small tusks similar in size is referred to a female.

    It was tested whether a marathon was completed faster by applying a scientifically based rather than a freely chosen nutritional strategy. Furthermore, gastrointestinal symptoms were evaluated. Nonelite runners performed a 10 km time trial 7 weeks before Copenhagen Marathon 2013 for estimation of running ability. Based on the time, runners were divided into two similar groups that eventually should perform the marathon by applying the two nutritional strategies. Matched pairs design was applied. Before the marathon, runners were paired based on their prerace running ability. Runners applying the freely chosen nutritional strategy (n = 14; 33.6 ± 9.6 years; 1.83 ± 0.09 m; 77.4 ± 10.6 kg; 45:40 ± 4:32 min for 10 km) could freely choose their in-race intake. Runners applying the scientifically based nutritional strategy (n = 14; 41.9 ± 7.6 years; 1.79 ± 0.11 m; 74.6 ± 14.5 kg; 45:44 ± 4:37 min) were targeting a combined in-race intake of energy gels and water, where the total intake amounted to approximately 0.750 L water, 60 g maltodextrin and glucose, 0.06 g sodium, and 0.09 g caffeine per hr. Gastrointestinal symptoms were assessed by a self-administered postrace questionnaire. Marathon time was 3:49:26 ± 0:25:05 and 3:38:31 ± 0:24:54 hr for runners applying the freely chosen and the scientifically based strategy, respectively (p = .010, effect size=-0.43). Certain runners experienced diverse serious gastrointestinal symptoms, but overall, symptoms were low and not different between groups (p > .05). In conclusion, nonelite runners completed a marathon on average 10:55 min, corresponding to 4.7%, faster by applying a scientifically based rather than a freely chosen nutritional strategy. Furthermore, average values of gastrointestinal symptoms were low and not different between groups.

  5. Developing a Robust Strategy for Implementing a Water Resources Master Plan in Lima, Peru

    Lima, the capital of Peru, faces significant water stress. It is the fifth largest metropolitan area in Latin America, and the second largest desert city in the world. The city has developed a Master Plan of major investment projects to improve water reliability until 2040. Yet key questions remain. Is the Master Plan sufficient for ensuring reliability in the face of deeply uncertain future climate change and demand? How do uncertain budget and project feasibility conditions shape Lima's options? How should the investments in the plan be prioritized, and can some be delayed? Lima is not alone in facing these planning challenges. Governments invest billions of dollars annually in long-term projects. Yet deep uncertainties pose formidable challenges to making near-term decisions that make long-term sense. The World Bank has spearheaded a community of practice on methods for Decision Making Under Deep Uncertainty (DMU). This pilot project in Peru is the first in-depth application of DMU techniques to water supply planning in a developing country. It builds on prior analysis done in New York, California, and for the Colorado River, yet shows how these methods can be applied in regions which do not have as advanced data or tools available. The project combines three methods in particular -- Robust Decision Making, Decision Scaling, and Adaptive Pathways -- to help Lima implement its Master Plan in a way that is robust, no-regret, and adaptive. It was done in close partnership with SEDAPAL, the water utility company in Lima, and in coordination with other national WRM and meteorological agencies. This talk will: Present the planning challenges Lima and other cities face, including climate change Describe DMU methodologies and how they were applied in collaboration with SEDAPAL Summarize recommendations for achieving long-term water reliability in Lima Suggest how these methodologies can benefit other investment projects in developing countries.

    Peru has been undergoing a revolution since the election of Alberto Fujimori as president in 1990. A revolution that is reversing many of the policies of the past 25 years and one which aims to bring Peru back into the mainstream of the world economy. All the enterprises nationalized in the heady days of the early 1970s are set up for privatization. The most important are the three mining companies: Hierro-Peru, Centromin, and Mineroo-Peru. It will not be easy to attract foreign investment after such a long period of political and economic instability but the rewards are there for the intrepid.

    As an experimental project, the Nutrition Communication and Behavior Change Component (NCBC) of the Indonesian Nutrition Development Program (UPGK) showed how social marketing could further the national program's goal of significantly improving the nutrition of Indonesia's young children and pregnant and nursing women. The social marketing approach successfully developed nutrition communication materials that were responsive to the needs, desires, and resources of the communities, particularly of the mothers and volunteer nutrition workers. Between 1977-79 Dr. I.B. Mantra, NCBC Director, established administrative and community infrastructures modeled after UPGK in 5 culturally diverse areas in Indonesia. In mid-1979, with technical assistance from Manoff International, the project departed from the approach of the national plan and embarked upon an unprecedented course with the formative evaluation of educational messages and a communication strategy. The success of the NCBC Component was to be judged by whether education -- as the sole intervention -- could produce significant improvements in the nutritional status of children and the improved nutrient intake of pregnant and lactating women in project communities. The 1st step was to design and execute qualitative research on the health and nutritional problems of children under 3 and pregnant and nursing women, consisting of in-depth household interviews, concept testing with mothers, and focus group interviews with kaders and community opinion leaders. Surveying was based on issues identified earlier by the Ministry of Health as most severe for the population overall. The qualitative investigation identified the need for change or reinforcement in particular nutrition-related behaviors. The target audience of mothers was segmented according to their needs during designated maternal stages and by the age-related dietary needs of their children under 3 years of age. This meant that only the most useful

    Background The aim of this study was to identify dietary strategies for physically active individuals with muscle dysmorphia based on a systematic literature review. Method References were included if the study population consisted of adults over 18 years old who were physically active in fitness centers. We identified reports through an electronic search ofScielo, Lilacs and Medline using the following keywords: muscle dysmorphia, vigorexia, distorted body image, and exercise. We found eight articles in Scielo, 17 in Medline and 12 in Lilacs. Among the total number of 37 articles, only 17 were eligible for inclusion in this review. Results The results indicated that the feeding strategies used by physically active individuals with muscle dysmorphia did not include planning or the supervision of a nutritionist. Diet included high protein and low fat foods and the ingestion of dietary and ergogenic supplements to reduce weight. Conclusion Physically active subjects with muscle dysmorphia could benefit from the help of nutritional professionals to evaluate energy estimation, guide the diet and its distribution in macronutrient and consider the principle of nutrition to functional recovery of the digestive process, promote liver detoxification, balance and guide to organic adequate intake of supplemental nutrients and other substances.

    The Peruvian National Tuberculosis Control Program issued guidelines in 2006 specifying criteria for culture and drug-susceptibility testing (DST), including district-level rapid DST. All patients referred for culture and DST in 2 districts of Lima, Peru, during January 2005–November 2008 were monitored prospectively. Of 1,846 patients, 1,241 (67.2%) had complete DST results for isoniazid and rifampin; 419 (33.8%) patients had multidrug-resistant (MDR) TB at the time of referral. Among patients with new smear-positive TB, household contact and suspected category I failure were associated with MDR TB, compared with concurrent regional surveillance data. Among previously treated patients with smear-positive TB, adult household contact, suspected category II failure, early relapse after category I, and multiple previous TB treatments were associated with MDR TB, compared with concurrent regional surveillance data. The proportion of MDR TB detected by using guidelines was higher than that detected by a concurrent national drug-resistance survey, indicating that the strategy effectively identified patients for DST.

    Background Taenia solium, a parasitic cestode that affects humans and pigs, is the leading cause of preventable epilepsy in the developing world. T. solium eggs are released into the environment through the stool of humans infected with an adult intestinal tapeworm (a condition called taeniasis), and cause cysticercosis when ingested by pigs or other humans. A control strategy to intervene within high-risk foci in endemic communities has been proposed as an alternative to mass antihelminthic treatment. In this ring strategy, antihelminthic treatment is targeted to humans and pigs residing within a 100 meter radius of a pig heavily-infected with cysticercosis. Our aim was to describe the roaming ranges of pigs in this region, and to evaluate whether the 100 meter radius rings encompass areas where risk factors for T. solium transmission, such as open human defecation and dense pig activity, are concentrated. Methodology/Principal Findings In this study, we used Global Positioning System (GPS) devices to track pig roaming ranges in two rural villages of northern Peru. We selected 41 pigs from two villages to participate in a 48-hour tracking period. Additionally, we surveyed all households to record the locations of open human defecation areas. We found that pigs spent a median of 82.8% (IQR: 73.5, 94.4) of their time roaming within 100 meters of their homes. The size of home ranges varied significantly by pig age, and 93% of the total time spent interacting with open human defecation areas occurred within 100 meters of pig residences. Conclusions/Significance These results indicate that 100 meter radius rings around heavily-infected pigs adequately capture the average pig’s roaming area (i.e., home range) and represent an area where the great majority of exposure to human feces occurs.

    Despite over 50 years of research, the field of sports nutrition continues to grow at a rapid rate. Whilst the traditional research focus was one that centred on strategies to maximise competition performance, emerging data in the last decade has demonstrated how both macronutrient and micronutrient availability can play a prominent role in regulating those cell signalling pathways that modulate skeletal muscle adaptations to endurance and resistance training. Nonetheless, in the context of exercise performance, it is clear that carbohydrate (but not fat) still remains king and that carefully chosen ergogenic aids (e.g. caffeine, creatine, sodium bicarbonate, beta-alanine, nitrates) can all promote performance in the correct exercise setting. In relation to exercise training, however, it is now thought that strategic periods of reduced carbohydrate and elevated dietary protein intake may enhance training adaptations whereas high carbohydrate availability and antioxidant supplementation may actually attenuate training adaptation. Emerging evidence also suggests that vitamin D may play a regulatory role in muscle regeneration and subsequent hypertrophy following damaging forms of exercise. Finally, novel compounds (albeit largely examined in rodent models) such as epicatechins, nicotinamide riboside, resveratrol, β-hydroxy β-methylbutyrate, phosphatidic acid and ursolic acid may also promote or attenuate skeletal muscle adaptations to endurance and strength training. When taken together, it is clear that sports nutrition is very much at the heart of the Olympic motto, Citius, Altius, Fortius (faster, higher, stronger).

    Access to nutrients is a key factor governing development, reproduction and ultimately fitness. Within social groups, contest-competition can fundamentally affect nutrient access, potentially leading to reproductive asymmetry among individuals. Previously, agent-based models have been combined with the Geometric Framework of nutrition to provide insight into how nutrition and social interactions affect one another. Here, we expand this modelling approach by incorporating evolutionary algorithms to explore how contest-competition over nutrient acquisition might affect the evolution of animal nutritional strategies. Specifically, we model tolerance of nutrient excesses and deficits when ingesting nutritionally imbalanced foods, which we term ‘nutritional latitude’; a higher degree of nutritional latitude constitutes a higher tolerance of nutritional excess and deficit. Our results indicate that a transition between two alternative strategies occurs at moderate to high levels of competition. When competition is low, individuals display a low level of nutritional latitude and regularly switch foods in search of an optimum. When food is scarce and contest-competition is intense, high nutritional latitude appears optimal, and individuals continue to consume an imbalanced food for longer periods before attempting to switch to an alternative. However, the relative balance of nutrients within available foods also strongly influences at what levels of competition, if any, transitions between these two strategies occur. Our models imply that competition combined with reproductive skew in social groups can play a role in the evolution of diet breadth. We discuss how the integration of agent-based, nutritional and evolutionary modelling may be applied in future studies to further understand the evolution of nutritional strategies across social and ecological contexts.

    In last decades modern societies are undergoing a rapid nutrition transition process that reinforces, at international level, the emergence of nutritional problems of contradictory nature, such as malnutrition and obesity. This represents a considerable challenge for contemporary Public Health leaders, who have been gradually developing a set of strategies which overwhelmingly adopt a population perspective. Nevertheless, the collective nature of these strategies could neglect the particular individual and family needs. We consider social participation as an approach to simultaneously reinforce both individual and population perspectives during the divers phases of development of Community Nutrition programs which tackle the paradoxical nature of this problematic. However in relation to some contextual factors, we find a growing trend to develop a more technocratic dimension of participatory practices, which distorts the emancipator and transformative potential of social participation. In order to avoid this tendency, we propose the use of the five intervention axes of the Ottawa Chart for Health Promotion as a guide for a systemic integration of social participation in planning, implementation and evaluation processes of Community Nutrition programs. We therefore take into account the integration of social participation in the efforts made in developing individual capacity-building, reinforcing collective action, creating enabling environments, health care reorganization, and finally, implementing nutritional and public health policies.

    OBJECTIVE: To describe geographical patterns of implementation of the Integrated Management of Childhood Illness (IMCI) strategy in three countries and to assess whether the strategy was implemented in areas with the most pressing child health needs. METHODS: We conducted interviews with key informants at the national and district levels in Brazil, Peru and the United Republic of Tanzania, and an ecological study of factors associated with health worker training in IMCI. Explanatory factors included district population, distance from the capital, human development index, other socioeconomic indicators and baseline mortality rates in children younger than five years. FINDINGS: In line with recommendations by WHO, early implementation districts were characterized by proximity to the capital and suitable training sites, presence of motivated health managers and a functioning health system. In the expansion phase, IMCI tended to be adopted by other districts with similar characteristics. In Brazil, uptake by poor and small municipalities and those further away from the state capital was significantly lower. In Peru, there was no association with distance from Lima, and a non-significant trend for IMCI adoption by small and poor departments. In the United Republic of Tanzania, the only statistically significant finding was a lower uptake by remote districts. Implementation was not associated with baseline mortality levels in any country studied. CONCLUSION: Whereas clear and reasonable guidelines are provided for selection of early use districts, no criteria for promoting IMCI expansion had been issued, and areas of greatest need were not prioritized. Equity analyses based on the geographical deployment of new programmes and strategies can contribute to assessing whether they are reaching those who need them most. PMID:17128359

    Implementation of a nutrition programme for team sports involves application of scientific research together with the social skills necessary to work with a sports medicine and coaching staff. Both field and court team sports are characterized by intermittent activity requiring a heavy reliance on dietary carbohydrate sources to maintain and replenish glycogen. Energy and substrate demands are high during pre-season training and matches, and moderate during training in the competitive season. Dietary planning must include enough carbohydrate on a moderate energy budget, while also meeting protein needs. Strength and power team sports require muscle-building programmes that must be accompanied by adequate nutrition, and simple anthropometric measurements can help the nutrition practitioner monitor and assess body composition periodically. Use of a body mass scale and a urine specific gravity refractometer can help identify athletes prone to dehydration. Sports beverages and caffeine are the most common supplements, while opinion on the practical effectiveness of creatine is divided. Late-maturing adolescent athletes become concerned about gaining size and muscle, and assessment of maturity status can be carried out with anthropometric procedures. An overriding consideration is that an individual approach is needed to meet each athlete's nutritional needs.

    Nutrition and diet therapy are at the center of health promotion activities and self-management of chronic diseases. To assist an individual in making informed decisions regarding his or her diet and increase adherence to dietary recommendations or treatments, healthcare professionals must select health information that is appropriate to the client's level of understanding. A systematic approach in the evaluation of patient education material, whether in print or on the World Wide Web, must focus on the information's content, literacy level, graphical displays, layout and typography, motivating principles, cultural relevance, and feasibility. Additional criteria should be evaluated when accessing Web sites and include source, site credibility, conflict of interest, disclaimer, disclosure, navigation, and interactivity information.

    Chris Pennington was an archetypal team player, strategist and networker. Clinical nutritional support has progressed remarkably since the 1970s and it has been a privilege to work in this field over this period during which teamwork, strategy development and networking have been crucial. British experience has been characterised by groups of individuals of differing professions and specialties coming together to enable progress to be made. This approach was initially in the form of nutrition support teams orientated to patient-centred ward-based care, then as hospital strategic committees and the concept of the 'patient journey'. Indeed, the formation of the British Association for Parenteral and Enteral Nutrition (now known as BAPEN) in 1992 required the statesmanlike burying of jealousies as societies came together into a multiprofessional association. With the understanding that disease-related malnutrition was highly prevalent it became apparent that it must be managed on a broad and organised clinical front. In the Organisation of Food and Nutritional Support in Hospitals a group of professionals developed for BAPEN concepts of hospital-wide organisation to tackle malnutrition that were based on previous reports, both national and international, and were made easily accessible from the BAPEN website, especially the 'Malnutrition Universal Screening Tool' and the National Institute for Health and Clinical Excellence nutrition guidelines. The coming together of six national clinical societies to develop evidence-based consensus guidelines for intravenous saline therapy (also on the BAPEN website) has shown that BAPEN can catalyse opinion well beyond its own nutritional constituency. In England Chris Pennington's Scottish lead is being followed by developing a patient-centred strategic framework for a managed home parenteral nutrition and intestinal failure national network. In research, education or clinical practice the engines of progress have been teams

    The purpose of this article was to evaluate and establish microfiltration (MF) operating conditions for vinasse (ethanol industries wastewater also known as stillage, slop, distillery effluent or dunder) concentration aiming to improve the use of its nutritive potential. The operating conditions influence permeate flux that has been evaluated by monitoring the flow rate profile during the operation on bench scale in different conditions (feed pH, aeration condition and recovery rate). From the results found, the process scale up was then effected. The bench scale findings showed that the vinasse microfiltration under air flow of 0.5 m(3).h(-1) between membrane fibers, with no pH adjustment, and recovery rate of 93% produced two flows, one of permeate that may be used to wash the sugarcane during the ethanol production processing, and the other of concentrate that contains a high organic compounds and nutrients concentration. This concentrate has additional potentiality of being used as organic compound supplement in contaminated soil bioremediation, and as a supplier of microbial biomass or substrate for biosurfactant production.

    Obesity and overweight are significant problems for children in the US, particularly for Hispanic children. This paper focuses on the children in families of immigrant Hispanic farmworkers, as farm work is the portal though which many immigrants come to the US. This paper (1) describes a model of the nutritional strategies of child feeding in farmworker families; and (2) uses this model to identify leverage points for efforts to improve the nutritional status of these children. In-depth interviews were conducted in Spanish with 33 mothers of 2–5 year old children in farmworker families recruited in North Carolina in 2010–2011. The purposive sample was balanced by farmworker status (migrant or seasonal), child age, and child gender. Interviews were transcribed and translated. Multiple coders and a team approach to analysis were used. Nutritional strategies centered on domains of procuring food, using food, and maintaining food security. The content of these domains reflected environmental factors (e.g., rural isolation, shared housing), contextual factors (e.g., beliefs about appropriate food, parenting style), and available resources (e.g., income, government programs). Environmental isolation and limited access to resources decrease the amount and diversity of household food supplies. Parental actions (parental sacrifices, reduced dietary variety) attempt to buffer children. Use of government food sources is valuable for eligible families. Leverage points are suggested that would change nutritional strategy components and lower the risk of overweight and obesity. Further prospective research is needed to verify the nutritional strategy identified and to test the ability of leverage points to prevent childhood obesity in this vulnerable population.

    Iron is an essential element for the growth and development of virtually all living organisms. As iron acquisition is critical for the pathogenesis, a host defense strategy during infection is to sequester iron to restrict the growth of invading pathogens. To counteract this strategy, bacteria such as Vibrio parahaemolyticus have adapted to such an environment by developing mechanisms to obtain iron from human hosts. This review focuses on the multiple strategies employed by V. parahaemolyticus to obtain nutritional iron from host sources. In these strategies are included the use of siderophores and xenosiderophores, proteases and iron-protein receptor. The host sources used by V. parahaemolyticus are the iron-containing proteins transferrin, hemoglobin, and hemin. The implications of iron acquisition systems in the virulence of V. parahaemolyticus are also discussed. PMID:26217331

    2002-01-01

    Exercise and nutrition represent primary countermeasures used during space flight to maintain or restore maximal aerobic capacity, musculoskeletal structure, and orthostatic function. However, no single exercise, dietary regimen, or combination of prescriptions has proven entirely effective in maintaining or restoring cardiovascular and musculoskeletal functions to preflight levels after prolonged space flight. As human space flight exposures increase in duration, identification, assessment, and development of various effective exercise- and nutrition-based protective procedures will become paramount. The application of adequate dietary intake in combination with effective exercise prescription will be based on identification of basic physiologic stimuli that maintain normal function in terrestrial gravity, and understanding how specific combinations of exercise characteristics (e.g., duration, frequency, intensity, and mode) can be combined with minimal nutritional requirements that mimic the stimuli normally produced by living in Earth's gravity environment. This can be accomplished only with greater emphasis of research on ground-based experiments targeted at understanding the interactions between caloric intake and expenditure during space flight. Future strategies for application of nutrition and exercise countermeasures for long-duration space missions must be directed to minimizing crew time and the impact on life-support resources.

    Lerner, R; Ferrando, D

    1995-01-01

    In Peru, the prevalence and consequences of inhalant abuse appear to be low in the general population and high among marginalized children. Inhalant use ranks third in lifetime prevalence after alcohol and tobacco. Most of the use appears to be infrequent. Among marginalized children, that is, children working in the streets but living at home or children living in the street, the problem of inhalant abuse is a serious problem. Among children working in the streets but living at home, the lifetime prevalence rate for inhalant abuse is high, ranging from 15 to 45 percent depending on the study being cited. For children living in the streets, the use of inhalant is even more severe. As mentioned earlier in this chapter, most of these street children use inhalants on a daily basis. The lack of research on the problem of inhalant abuse is a serious impediment to development of intervention programs and strategies to address this problem in Peru. Epidemiologic and ethnographic research on the nature and extent of inhalant abuse are obvious prerequisites to targeted treatment and preventive intervention programs. The urgent need for current and valid data is underscored by the unique vulnerability of the youthful population at risk and the undisputed harm that results from chronic abuse of inhalants. Nonetheless, it is important to mention several programs that work with street children. Some, such as the Information and Education Center for the Prevention of Drug Abuse, Generation, and Centro Integracion de Menores en Abandono have shelters where street children are offered transition to a less marginal lifestyle. Teams of street educators provide the children with practical solutions and gain their confidence, as well as offer them alternative socialization experiences to help them survive the streets and avoid the often repressive and counterproductive environments typical of many institutions. Most of the children who go through these programs tend to abandon

    Background In developing countries, deficiencies in essential micronutrients are common, particularly in pregnant women. Although, biochemical indicators of diet and nutrition are useful to assess nutritional status, few studies have examined such indicators throughout pregnancy in women in developing countries. Methods The primary objective of this study was to assess the nutritional status of 78 Peruvian women throughout pregnancy for 16 different nutritional indicators including fat-soluble vitamins and carotenoids, iron-status indicators, and selenium. Venous blood samples from which serum was prepared were collected during trimesters one (n = 78), two (n = 65), three (n = 62), and at term via the umbilical cord (n = 52). Questionnaires were completed to determine the demographic characteristics of subjects. Linear mixed effects models were used to study the associations between each maternal indicator and the demographic characteristics. Results None of the women were vitamin A and E deficient at any stage of pregnancy and only 1/62 women (1.6%) was selenium deficient during the third trimester. However, 6.4%, 44% and 64% of women had ferritin levels indicative of iron deficiency during the first, second and third trimester, respectively. Statistically significant changes (p ≤ 0.05) throughout pregnancy were noted for 15/16 nutritional indicators for this Peruvian cohort, with little-to-no association with demographic characteristics. Three carotenoids (beta-carotene, beta-cryptoxanthin and trans-lycopene) were significantly associated with education status, while trans-lycopene was associated with age and beta-cryptoxanthin with SES (p < 0.05). Concentrations of retinol, tocopherol, beta-cryptoxanthin, lutein + zeaxanthin and selenium were lower in cord serum compared with maternal serum (p < 0.05). Conversely, levels of iron status indicators (ferritin, transferrin saturation and iron) were higher in cord serum (p < 0

    Consumers demand both safer and more nutritious food products exempt of non-natural origin preservatives or other food additives. In this frame, products with lower fat content and/or a higher ratio in unsaturated fatty acids, especially n-3 fatty acids, are desired because these lipids can help prevent the development of cardiovascular and inflammatory pathologies. The intake of meat products is of interest because they are an excellent source of vitamins and minerals. In addition, the shelf-life of meat products can be extended by the presence of natural antioxidants coming from different sources such as plant extracts. Therefore, different strategies have been studied to improve the nutritional value, oxidative stability, and sensory characteristics of meat products and eggs through different mineral and natural dietary supplements. In comparison to other strategies, dietary supplements present the advantage that first the living animals may efficiently distribute the compounds throughout the tissues and second, the dietary supplementation is safer because the resulting enriched meat products and eggs ensure tolerable amounts in humans. Poultry meats and eggs are widely consumed and their fatty acid profile and tocopherol content can be easily modified through different dietary strategies thus being excellent models to improve their nutritional value and oxidative stability.

    Objectives to describe the maternal eating and physical activity strategies (monitoring, discipline, control, limits and reinforcement) [MEES]; to determine the relation between MEES and the child's nutritional status [body mass index (BMI) and body fat percentage (BFP)]; to verify whether the MEES differ according to the child's nutritional status. Method participants were 558 mothers and children (3 to 11 years of age) who studied at public schools. The Parental Strategies for Eating and Activity Scale (PEAS) was applied and the child's weight, height and BFP were measured. For analysis purposes, descriptive statistics were obtained, using multiple linear regression and the Kruskal-Wallis test. Results the highest mean score was found for reinforcement (62.72) and the lowest for control (50.07). Discipline, control and limits explained 12% of the BMI, while discipline and control explained 6% of the BFP. Greater control is found for obese children (χ2=38.36, p=0.001) and greater reinforcement for underweight children (χ2=7.19, p<0.05). Conclusions the mothers exert greater control (pressure to eat) over obese children and greater recognition (congratulating due to healthy eating) in underweight children. Modifications in parental strategies are recommended with a view to strengthening healthy eating and physical activity habits. PMID:26107837

    Obesity, diet and physical inactivity are risk factors for some cancers. Grantees of the National Comprehensive Cancer Control Program (NCCCP) in US states, tribes, and territories develop plans to coordinate funding and activities for cancer prevention and control. Including information and goals related to nutrition and physical activity (NPA) is a key opportunity for primary cancer prevention, but it is currently unclear to what extent NCCCP plans address these issues. We reviewed 69 NCCCP plans and searched for terms related to NPA. Plans were coded as (1) knowledge of NPA and cancer link; (2) goals to improve NPA behaviors; and (3) strategies to increase healthy NPA activities, environments, or systems changes. NPA content was consistently included in all cancer plans examined across all years. Only 4 (6 %) outlined only the relationship between NPA and cancer without goals or strategies. Fifty-nine plans (89 %) contained goals or strategies related to NPA, with 53 (82 %) including both. However, numbers of goals, strategies, and detail provided varied widely. All programs recognized the importance of NPA in cancer prevention. Most plans included NPA goals and strategies. Increasing the presence of NPA strategies that can be modified or adapted appropriately locally could help with more widespread implementation and measurement of NPA interventions.

    Obesity, the prevalence of which is still on the rise, is related to the main chronic diseases affecting the health of the population. Therefore, in 2004, the World Health Assembly approved the Global Strategy on Diet, Physical Activity and Health with the aim of reducing the risk factors of nontransmittable diseases related to unhealthy diets and physical inactivity. Along this same line, the Spanish Ministry of Health and Consumer Affairs began implementing the NAOS Strategy in 2005 as a platform from which to include and promote all those initiatives contributing to achieving the necessary social change in the promotion of healthy eating and the prevention of a sedentary lifestyle by meeting certain specific challenges within different scopes of action. The NAOS Strategy extends far beyond the healthcare and educational areas, by combining actions in all those sectors of society playing a role in preventing obesity. Informative campaigns, agreements with public and private institutions, voluntary working agreements, educational programs and supporting health promotion initiatives are some of the activities being carried out as part of the NAOS Strategy. Carrying out these activities and incorporating yet others, in conjunction with the work of evaluating and monitoring all of these activities, will be what is going to make it possible to maintain a high degree of effectiveness in preventing obesity.

    Periods of immobilisation are often associated with pathologies and/or ageing. These periods of muscle disuse induce muscle atrophy which could worsen the pathology or elderly frailty. If muscle mass loss has positive effects in the short term, a sustained/uncontrolled muscle mass loss is deleterious for health. Muscle mass recovery following immobilisation-induced atrophy could be critical, particularly when it is uncompleted as observed during ageing. Exercise, the best way to recover muscle mass, is not always applicable. So, other approaches such as nutritional strategies are needed to limit muscle wasting and to improve muscle mass recovery in such situations. The present review discusses mechanisms involved in muscle atrophy following disuse and during recovery and emphasises the effect of age in these mechanisms. In addition, the efficiency of nutritional strategies proposed to limit muscle mass loss during disuse and to improve protein gain during recovery (leucine supplementation, whey proteins, antioxidants and anti-inflammatory compounds, energy intake) is also discussed.

    Modern research in food science and nutrition is moving from classical methodologies to advanced analytical strategies in which MS-based techniques play a crucial role. In this context, Foodomics has been recently defined as a new discipline that studies food and nutrition domains through the application of advanced omics technologies in which MS techniques are considered indispensable. Applications of Foodomics include the genomic, transcriptomic, proteomic, and/or metabolomic study of foods for compound profiling, authenticity, and/or biomarker-detection related to food quality or safety; the development of new transgenic foods, food contaminants, and whole toxicity studies; new investigations on food bioactivity, food effects on human health, etc. This review work does not intend to provide an exhaustive revision of the many works published so far on food analysis using MS techniques. The aim of the present work is to provide an overview of the different MS-based strategies that have been (or can be) applied in the new field of Foodomics, discussing their advantages and drawbacks. Besides, some ideas about the foreseen development and applications of MS-techniques in this new discipline are also provided.

  6. Nutritional strategies to combat Salmonella in mono-gastric food animal production.

    PubMed

    Berge, A C; Wierup, M

    2012-04-01

    Nutritional strategies to minimize Salmonella in food animal production are one of the key components in producing safer food. The current European approach is to use a farm-to-fork strategy, where each sector must implement measures to minimize and reduce Salmonella contamination. In the pre-harvest phase, this means that all available tools need to be used such as implementation of biosecurity measures, control of Salmonella infections in animals at the farm as well as in transport and trade, optimal housing and management including cleaning, disinfection procedures as well as efforts to achieve Salmonella-free feed production. This paper describes some nutritional strategies that could be used in farm control programmes in the major mono-gastric food production animals: poultry and pigs. Initially, it is important to prevent the introduction of Salmonella onto the farm through Salmonella-contaminated feed and this risk is reduced through heat treatment and the use of organic acids and their salts and formaldehyde. Microbiological sampling and monitoring for Salmonella in the feed mills is required to minimize the introduction of Salmonella via feed onto the farm. In addition, feed withdrawal may create a stressful situation in animals, resulting in an increase in Salmonella shedding. Physical feed characteristics such as coarse-ground meal to pigs can delay gastric emptying, thereby increasing the acidity of the gut and thus reducing the possible prevalence of Salmonella. Coarse-ground grains and access to litter have also been shown to decrease Salmonella shedding in poultry. The feed can also modify the gastro-intestinal tract microflora and influence the immune system, which can minimize Salmonella colonization and shedding. Feed additives, such as organic acids, short- and medium-chain fatty acids, probiotics, including competitive exclusion cultures, prebiotics and certain specific carbohydrates, such as mannan-based compounds, egg proteins, essential oils

    Hypoglycaemia remains the major limiting factor for adequate diabetes control for patients with type 1 diabetes (T1D), especially during the night-time. Although nutritional strategies for nocturnal hypoglycaemia (NH) prevention are regularly suggested in clinical practice, there is no evidence-based recommendation for the usefulness and optimal composition of a bedtime snack. The aim of this narrative review was to analyse the current state of knowledge on nutritional strategies to prevent NH in individuals with T1D. A literature search was conducted, using PubMed and Medline (1946 to 2013); 16 studies were retrieved. Overall, the level of evidence was low. Results indicated that a calibrated bedtime snack based on bedtime blood glucose (BG) level could be effective to reduce NH occurrence for patients treated with human or animal insulin (short-acting combined with lente, ultralente and/or intermediate-acting insulin), but there is no evidence for patients treated with insulin analogues as part of multiple daily injections or insulin pump regimen. Some evidence suggests that including uncooked cornstarch or alanine in the bedtime snack composition could provide some benefits for the prevention of NH. Individualized recommendations of a bedtime snack intake for patients or situations at high risk for NH (long standing diabetes, hypoglycaemia unawareness, prior physical activity, alcohol consumption, bedtime BG close to hypoglycaemia threshold) appear as a prudent recommendation. On the basis of the available evidence, a bedtime snack cannot be recommended systematically but it might be useful if prescribed in an individualized fashion; further research is needed to evaluate these strategies.

    Two major domestic terrorist groups have plagued Peru over the past 20 years, the Sendero Luminoso or "Shining Path" (SL) and the Revolutionary Movement Túpac Amaru (MRTA). On 28 August 2003, the Peruvian Truth and Reconciliation Commission reported that an estimated 69,280 persons were killed in the internal conflict in Peru from 1980 to 2000. Most of the victims were farmers (56%), most attacks occurred in rural settings (79%), and the SL was responsible for most of the deaths (54%). Aggressive anti-terrorism efforts by police and military during this period, often at the expense of basic human rights, also contributed to this large burden of terrorism on Peru. During the 1990s, terrorist attacks in Peru had spread to its urban areas. On 17 December 1996, 22 members of MRTA took over the Japanese ambassador's residence in Lima, holding 72 hostages until the grounds were stormed by Peruvian special forces on 23 April 1997. Until recently, emergency planning and preparedness for terrorism-related events in Peru were largely underdeveloped. In the last five years, Peru has taken two key steps towards developing a mature emergency response system, with the establishment of the country's first emergency medicine residency training program and the construction of the first dedicated trauma center in Lima.

    Food resources consumed by primates vary markedly in nutritional content. As a result, foragers must develop a feeding strategy to select resources that balance energy and macronutrient intake and reduce the consumption of fiber and toxins. In this study, we collected data on dietary patterns, rates of food consumption, and weight of food items consumed and combined them with published values of the nutritional content of Neotropical foods to estimate energy and nutrient intake during a 10-month period in two groups (N=16 individuals) of black howler monkeys (Alouatta pigra) inhabiting Palenque National Park, Mexico. Although howler monkeys are generally assumed to exploit a leaf-dominated diet and be energy-limited, our results indicated that black howlers met their estimated energy requirements, consuming an average of 0.58 MJ of overall energy per metabolic body mass per day. The howlers also surpassed protein requirements by consuming an average of 8.2 g of protein per metabolic body mass per day. The amount of time they spent resting was not correlated with the amount of leaves or fruit in the diet or with overall energy intake. Therefore, despite consuming a leaf-heavy diet during some months of the year, black howlers do not appear to be energy-limited. Additionally, the howlers maintained a relatively consistent level of average daily protein energy intake regardless of diet composition, while non-protein energy intake varied in response to the amount of ripe fruits consumed. Although our use of published nutritional data introduces error, these findings suggest that black howler feeding ecology is more similar to other fruit-eating atelines than previously suspected, and several common assumptions regarding howler behavior and feeding ecology need to be reexamined.

    2013-03-01

    The recently sequenced cattle (Bos taurus) genome unraveled the unique genomic features of the species and provided the molecular basis for applying a systemic approach to systematically link genomic information to metabolic traits. Comparative analysis has identified a variety of evolutionary adaptive features in the cattle genome, such as an expansion of the gene families related to the rumen function, large number of chromosomal rearrangements affecting regulation of genes for lactation, and chromosomal rearrangements that are associated with segmental duplications and copy number variations. Metabolic reconstruction of the cattle genome has revealed that core metabolic pathways are highly conserved among mammals although five metabolic genes are deleted or highly diverged and seven metabolic genes are present in duplicate in the cattle genome compared to their human counter parts. The evolutionary loss and gain of metabolic genes in the cattle genome may reflect metabolic adaptations of cattle. Metabolic reconstruction also provides a platform for better understanding of metabolic regulation in cattle and ruminants. A substantial body of transcriptomics data from dairy and beef cattle under different nutritional management and across different stages of growth and lactation are already available and will aid in linking the genome with metabolism and nutritional physiology of cattle. Application of cattle genomics has great potential for future development of nutritional strategies to improve efficiency and sustainability of beef and milk production. One of the biggest challenges is to integrate genomic and phenotypic data and interpret them in a biological and practical platform. Systems biology, a holistic and systemic approach, will be very useful in overcoming this challenge.

    Background: The research to date does not present an articulated approach to ensure nutrition and food systems education is systematically implemented within schools. This paper aimed to investigate food experts’ views of the best strategies to improve school-leavers’ knowledge of nutrition and food systems. Methods: In this qualitative study, 28 Iranian food and nutrition experts from four major provinces (Tehran, Fars, Isfahan, and Gilan) were selected and agreed to be interviewed. Required data were collected through in-depth, semi-structured, face-to-face, or telephone interviews and were analyzed thematically using NVivo. Results: The experts’ suggested strategies to improve Iranian school-leavers’ knowledge of nutrition and food systems fell into three key themes: Policy, education processes, and supportive environments. Together they formed an overarching theme of a multileveled system approach for transferring knowledge. Conclusions: Development of a scaffolded education program could assist curriculum developers and policy makers to assess and update current nutrition and food systems education programs in schools. Insights gained about education initiatives in one country such as Iran can provide an important impetus to support nutrition and food system education more widely. PMID:27857832

  12. Nutritional strategies to support adaptation to high-intensity interval training in team sports.

    PubMed

    Gibala, Martin J

    2013-01-01

    Team sports are characterized by intermittent high-intensity activity patterns. Typically, play consists of short periods of very intense or all-out efforts interspersed with longer periods of low-intensity activity. Fatigue is a complex, multi-factorial process, but intense intermittent exercise performance can potentially be limited by reduced availability of substrates stored in skeletal muscle and/or metabolic by-products associated with fuel breakdown. High-intensity interval training (HIT) has been shown to induce adaptations in skeletal muscle that enhance the capacity for both oxidative and non-oxidative metabolism. Nutrient availability is a potent modulator of many acute physiological responses to exercise, including various molecular signaling pathways that are believed to regulate cellular adaptation to training. Several nutritional strategies have also been reported to acutely alter metabolism and enhance intermittent high-intensity exercise performance. However, relatively little is known regarding the effect of chronic interventions, and whether supplementation over a period of weeks or months augments HIT-induced physiological remodeling and promotes greater performance adaptations. Theoretically, a nutritional intervention could augment HIT adaptation by improving energy metabolism during exercise, which could facilitate greater total work and an enhanced chronic training stimulus, or promoting some aspect of the adaptive response during recovery, which could lead to enhanced physiological adaptations over time.

    Variation is inherent to living systems. Because feeding strategies are applied to groups of pigs, it contributes to the inefficient use of natural resources and may even amplify the variation among pigs at slaughter. Precision pork production and precision feeding, through management of the variation among individuals, may contribute to improving the efficiency of animal production systems. This approach relies on the prediction of the response of the animal to the nutrient supply, the continuous monitoring of the response, and a system to control nutrient supply. Most nutritional models of pig growth are based on the partitioning of nutrients between energy expenditure, and protein and lipid deposition. However, the link between chemical body composition and tissue growth, tissue composition and thus carcass quality remains a challenge in modeling. The potential of precision pork production also depends on the (real-time) information that can be obtained to control growth and carcass quality.

    2015-11-01

    Intramuscular acidosis is a contributing factor to fatigue during high-intensity exercise. Many nutritional strategies aiming to increase intra- and extracellular buffering capacity have been investigated. Among these, supplementation of beta-alanine (~3-6.4 g/day for 4 weeks or longer), the rate-limiting factor to the intramuscular synthesis of carnosine (i.e. an intracellular buffer), has been shown to result in positive effects on exercise performance in which acidosis is a contributing factor to fatigue. Furthermore, sodium bicarbonate, sodium citrate and sodium/calcium lactate supplementation have been employed in an attempt to increase the extracellular buffering capacity. Although all attempts have increased blood bicarbonate concentrations, evidence indicates that sodium bicarbonate (0.3 g/kg body mass) is the most effective in improving high-intensity exercise performance. The evidence supporting the ergogenic effects of sodium citrate and lactate remain weak. These nutritional strategies are not without side effects, as gastrointestinal distress is often associated with the effective doses of sodium bicarbonate, sodium citrate and calcium lactate. Similarly, paresthesia (i.e. tingling sensation of the skin) is currently the only known side effect associated with beta-alanine supplementation, and it is caused by the acute elevation in plasma beta-alanine concentration after a single dose of beta-alanine. Finally, the co-supplementation of beta-alanine and sodium bicarbonate may result in additive ergogenic gains during high-intensity exercise, although studies are required to investigate this combination in a wide range of sports.

    Chronic kidney disease (CKD) requires extensive changes to food and lifestyle. Poor adherence to diet, medications, and treatments has been estimated to vary between 20% and 70%, which in turn can contribute to increased mortality and morbidity. Delivering effective nutritional advice in patients with CKD coordinates multiple diet components including calories, protein, sodium, potassium, calcium, phosphorus, and fluid. Dietary intake studies have shown difficulty in adhering to the scope and complexity of the CKD diet parameters. No single educational or clinical strategy has been shown to be consistently effective across CKD populations. Highest adherence has been observed when both diet and education efforts are individualized to each patient and adapted over time to changing lifestyle and CKD variables. This narrative review and commentary summarizes nutrition education literature and published strategies for providing nutritional advice in CKD. A cohort of practical and effective strategies for increasing dietary adherence to nutritional advice are provided that include communicating with “talking control” principles, integrating patient-owned technology, acknowledging the typical food pattern may be snacking rather than formal meals, focusing on a single goal rather than multiple goals, creating active learning and coping strategies (frozen sandwiches, visual hands-on activities, planting herb gardens), and involving the total patient food environment.

    The focus of this paper is to explore better strategies for optimising bone strength and reducing risk of fracture, while at the same time decreasing risk of cardiovascular disease. The majority of Americans do not consume the current recommended dietary allowance for calcium, and the lifetime risk of osteoporosis is about 50%. However, traditional mononutrient calcium supplements may not be ideal. We comprehensively and systematically reviewed the scientific literature in order to determine the optimal dietary strategies and nutritional supplements for long-term skeletal health and cardiovascular health. To summarise, the following steps may be helpful for building strong bones while maintaining soft and supple arteries: (1) calcium is best obtained from dietary sources rather than supplements; (2) ensure that adequate animal protein intake is coupled with calcium intake of 1000 mg/day; (3) maintain vitamin D levels in the normal range; (4) increase intake of fruits and vegetables to alkalinise the system and promote bone health; (5) concomitantly increase potassium consumption while reducing sodium intake; (6) consider increasing the intake of foods rich in vitamins K1 and K2; (7) consider including bones in the diet; they are a rich source of calcium-hydroxyapatite and many other nutrients needed for building bone.

    Background: Reproductive years represent a major proportion of women‟s life. This review focuses on recommended nutritional considerations, physical activity pattern as well as the effect of nutrition education (NE) on behavior modification and health outcomes of women of reproductive age using either single-level, multiple-level or community-level interventions. Methods: For this narrative review, numerous searches were conducted on databases of PubMed, Science Direct and Google Scholar search engine using the keywords women, reproductive age, NE, interventions, community-based. Results: Even though single intervention is effective, multiple intervention programmes in addition to behavior modification components are even more successful in terms of modified behaviors and health outcomes. Moreover, community based interventions using multilevel strategies are further useful for improved health outcomes and behavior modification. Conclusion: NE programmes have been effective in positive behavior modification measured in terms of eating pattern and health quality. Thus, it is recommended that health professionals use multiple intervention strategies at community level to ensure improved outcomes. Political support is also required to create culturally sensitive methods of delivering nutritional programmes. Finally, as policy is dependent on program cost, nutritional programmes need to combine methods of cost analysis to show cost effectiveness of supplying adequate nutrition for women throughout the lifecycle.

    This study assessed lubricant use during receptive anal intercourse (RAI) among Peruvian men who have sex with men (MSM) and willingness to use a hypothetical rectal microbicide (RM) formulated as a lubricant to prevent HIV infection. Data were collected from 843 Peruvian MSM for the 2008 HIV Sentinel Surveillance using a computerized self-interview. Half of the participants reported using a lubricant with their last sex partner during RAI, while 77% were willing to use a lubricant to prevent HIV transmission. Lubricant use with last sex partner was significantly associated with unprotected RAI (odds ratio [OR] 1.59, 95% confidence interval [CI], 1.23, 2.05; P < 0.001) and willingness to use a future lubricant RM (OR 1.56, 95% CI: 1.24, 1.95; P < 0.001).

    Overweight and obesity are major world global health challenges of the 21st century. Mexico is not an exception. Approximately 70% of the adult Mexican population has an excessive body weight. The prevalence of obesity and overweight in Mexican school children aged 5-11 is also high: one child in four is overweight. In light of the seriousness of the situation, the solutions for this problem are based on modification of the environments and change of individual habits and behaviors related to nutrition and physical activity. As a result, the Mexican government, public sector and academy established three common goals and 10 priority objectives that are expressed in the National Agreement for Nutritional Health-Strategy to Control Overweight and Obesity. The obesity problem requires interventions and policies that reside outside of the health sector domain, key aspects of this public health policy was agreement among all stakeholders on cross-cutting actions. The best examples of National Agreement's inter-sectorial action implementation is in the school setting and Code of 'Self Regulation' on Advertising of Food and Non-Alcoholic Beverages to Children introduced by the food and beverage industry. The ultimate goal of this national policy is to provide the strategic plan for healthy weight and better health, by promoting healthy lifestyles focused on correct diet and physical activity in all life stages, from pregnancy and early childhood and on into adulthood by a multi stakeholder approach. Although there have been great achievements in some areas of implementation, there are still challenges to confront.

    Background Chrysophytes are protist model species in ecology and ecophysiology and important grazers of bacteria-sized microorganisms and primary producers. However, they have not yet been investigated in detail at the molecular level, and no genomic and only little transcriptomic information is available. Chrysophytes exhibit different trophic modes: while phototrophic chrysophytes perform only photosynthesis, mixotrophs can gain carbon from bacterial food as well as from photosynthesis, and heterotrophs solely feed on bacteria-sized microorganisms. Recent phylogenies and megasystematics demonstrate an immense complexity of eukaryotic diversity with numerous transitions between phototrophic and heterotrophic organisms. The question we aim to answer is how the diverse nutritional strategies, accompanied or brought about by a reduction of the plasmid and size reduction in heterotrophic strains, affect physiology and molecular processes. Results We sequenced the mRNA of 18 chrysophyte strains on the Illumina HiSeq platform and analysed the transcriptomes to determine relations between the trophic mode (mixotrophic vs. heterotrophic) and gene expression. We observed an enrichment of genes for photosynthesis, porphyrin and chlorophyll metabolism for phototrophic and mixotrophic strains that can perform photosynthesis. Genes involved in nutrient absorption, environmental information processing and various transporters (e.g., monosaccharide, peptide, lipid transporters) were present or highly expressed only in heterotrophic strains that have to sense, digest and absorb bacterial food. We furthermore present a transcriptome-based alignment-free phylogeny construction approach using transcripts assembled from short reads to determine the evolutionary relationships between the strains and the possible influence of nutritional strategies on the reconstructed phylogeny. We discuss the resulting phylogenies in comparison to those from established approaches based on ribosomal

    1997-01-01

    Lima's population grew from 1 million to 7 million during 1969-89, almost entirely due to rural-urban immigration. Other urban areas such as Iquitos experienced similar growth over the period. National, regional, and municipal governments have been working to restore civil order in the country and to bring basic health, sanitation, and education programs to the population. However, language, attitudinal, and cultural differences impede progress in this diverse and changing country. Peru's young population of median age 21 years presents a challenge to the development and implementation of effective reproductive health care programs for the country. Pathfinder's work in Peru is helped by current President Alberto Fujimori's strong and active support for family planning. In the face of strong opposition from the Roman Catholic Church, President Fujimori has held onto his conviction and commitment to reduce levels of maternal morbidity and mortality in Peru by increasing the accessibility of family planning programs. Pathfinder's work in Peru with the US Agency for International Development (USAID) includes the 5-year program Project 2000 designed to improve maternal and child health in 12 priority regions of the country. Pathfinder is also working with USAID to link family planning to postpartum services in 30 public hospitals throughout the country. New programs will be launched with contributions from individuals and foundations.

    We measured plasma concentrations of variables associated with lipid metabolism (free fatty acids, glycerol, triglyceride, and ??- hydroxybutyrate), protein metabolism (uric acid), and baseline corticosterone to characterize the nutritional state of incubating king eiders Somateria spectabilis and relate this to incubation constancy at two sites, Kuparuk and Teshekpuk, in northern Alaska. King eiders at both sites appeared to employ a partial-income incubation strategy, relying on both endogenous and exogenous energy resources. Females maintained high invariant levels of free fatty acids, ??-hydroxybutyrate, and glycerol throughout incubation, indicating that fat reserves were a major energy source, and not completely depleted during incubation. Similarly, uric acid did not increase, suggesting effective protein sparing or protein ingestion and adequate lipid reserves throughout incubation. Baseline corticosterone and triglyceride levels increased during incubation, indicative of an increase in foraging during late stages of incubation. Incubating females at Kuparuk had higher triglyceride concentrations but also had higher ??-hydroxybutyrate concentrations than females at Teshekpuk. This dichotomy may reflect a short-term signal of feeding overlaying the longer-term signal of reliance on endogenous lipid reserves due to higher food intake yet higher metabolic costs at Kuparuk because of its colder environment. Incubation constancy was not correlated with plasma concentrations of lipid or protein metabolites. ?? 2008 The Authors.

    Overweight and obesity in children and adolescents represent a serious public health problem in Peru, with high costs for society that require the implementation of a set of public policies directed toward its control. Thus, interventions have been proposed as the regulation of advertising of unhealthy foods, self-regulation, the implementation of kiosks healthy and nutritional labeling. From the analysis of the problem of overweight and obesity in children and adolescents in Peru, this article is a narrative review of such interventions.

    Plant and soil types are usually considered as the two main drivers of the rhizosphere microbial communities. The aim of this work was to study the effect of both N availability and plant genotype on the plant associated rhizosphere microbial communities, in relation to the nutritional strategies of the plant-microbe interactions, for six contrasted Medicago truncatula genotypes. The plants were provided with two different nutrient solutions varying in their nitrate concentrations (0 mM and 10 mM). First, the influence of both nitrogen availability and Medicago truncatula genotype on the genetic structure of the soil bacterial and fungal communities was determined by DNA fingerprint using Automated Ribosomal Intergenic Spacer Analysis (ARISA). Secondly, the different nutritional strategies of the plant-microbe interactions were evaluated using an ecophysiological framework. We observed that nitrogen availability affected rhizosphere bacterial communities only in presence of the plant. Furthermore, we showed that the influence of nitrogen availability on rhizosphere bacterial communities was dependent on the different genotypes of Medicago truncatula. Finally, the nutritional strategies of the plant varied greatly in response to a modification of nitrogen availability. A new conceptual framework was thus developed to study plant-microbe interactions. This framework led to the identification of three contrasted structural and functional adaptive responses of plant-microbe interactions to nitrogen availability.

    The objective of this study was to explore whether singing an educational song would be effective in improving older adults' knowledge about nutrition. We used a randomized controlled design to determine whether singing an educational song would result in increased nutrition knowledge in a low-income population of older adults compared to a control group of similar adults who did not sing the song. Eighteen congregate nutrition sites were randomly assigned to the treatment or control group. Analysis via independent samples t -test showed the knowledge gain mean scores for the treatment group were significantly ( P  < 0.05) greater than those of the control group. This study supports a unique new approach to increasing nutrition knowledge of older adults by using music.

    2007-01-01

    In 2004, a specific need for data on mercury use in South America was indicated by the United Nations Environmental Programme-Chemicals (UNEP-Chemicals) at a workshop on regional mercury pollution that took place in Buenos Aires, Argentina. Mercury has long been mined and used in South America for artisanal gold mining and imported for chlor-alkali production, dental amalgam, and other uses. The U.S. Geological Survey (USGS) provides information on domestic and international mercury production, trade, prices, sources, and recycling in its annual Minerals Yearbook mercury chapter. Therefore, in response to UNEP-Chemicals, the USGS, in collaboration with the Economic Section of the U.S. Embassy, Lima, has herein compiled data on Peru's exports, imports, and byproduct production of mercury. Peru was selected for this inventory because it has a 2000-year history of mercury production and use, and continues today as an important source of mercury for the global market, as a byproduct from its gold mines. Peru is a regional distributor of imported mercury and user of mercury for artisanal gold mining and chlor-alkali production. Peruvian customs data showed that 22 metric tons (t) of byproduct mercury was exported to the United States in 2006. Transshipped mercury was exported to Brazil (1 t), Colombia (1 t), and Guyana (1 t). Mercury was imported from the United States (54 t), Spain (19 t), and Kyrgyzstan (8 t) in 2006 and was used for artisanal gold mining, chlor-alkali production, dental amalgam, or transshipment to other countries in the region. Site visits and interviews provided information on the use and disposition of mercury for artisanal gold mining and other uses. Peru also imports mercury-containing batteries, electronics and computers, fluorescent lamps, and thermometers. In 2006, Peru imported approximately 1,900 t of a wide variety of fluorescent lamps; however, the mercury contained in these lamps, a minimum of approximately 76 kilograms (kg), and in

    There is controversy about fish-oil supplementation and oxidative damage. This ambiguity should be explored to elucidate its role as modulator of oxidative stress, especially during gestation and postnatal life. This is the objective of this study. One hundred ten pregnant women were divided in two groups: control group CT (400 mL/day of the control dairy drink); supplemented group FO (400 mL/day of the fish oil-enriched dairy drink (±400-mg EPA-DHA/day)). Different biomarkers of oxidative damage were determined in the mother's at enrolment, at delivery and at 2.5 and 4 months postpartum and newborns at delivery and at 2.5 months postpartum. Omega-3 LC-PUFA supplementation during pregnancy and lactation decreased plasma hydroperoxides especially in newborn at delivery (P = 0.001) and 2.5 months (P = 0.006), increased superoxide dismutase (SOD) and catalase (CAT) in mothers at delivery (P = 0.024 (SOD)) and after 2.5 months (P = 0.040 (CAT)) and in newborns at 2.5 months (P = 0.035 (SOD); P = 0.021 (CAT)). Also, supplementation increased α-tocoferol in mothers at 2.5 months (P = 0.030) and in umbilical cord artery (P = 0.039). Higher levels of CoQ10 were found in mothers at delivery (P = 0.039) as well as in umbilical cord vein (P = 0.024) and artery (P = 0.036). Our supplementation prevents the oxidative stress in the mother and neonate during the first months of postnatal life, being a potential preventive nutritional strategy to prevent functional alterations associated with oxidative stress that have an important repercussion for the neonate development in the early postnatal life.

    Nutrition plays a key role in allowing the numerous training hours to be translated into useful adaptive responses of various tissues in the individual athlete. Research over the last decade has shown many examples of the impact of dietary interventions to modulate the skeletal muscle adaptive response to prolonged exercise training. Proper nutritional coaching should be applied throughout both training and competition, each with their specific requirements regarding nutrient provision. Such dietary support will improve exercise training efficiency and, as such, further increase performance capacity. Here, we provide an overview on the properties of various nutritional interventions that may be useful to support the adaptive response to exercise training and competition and, as such, to augment exercise training efficiency.

    Despite the global transition to overnutrition, stunting affected approximately 159 million children worldwide in 2014, while an estimated 50 million children were wasted. India is an important front in the fight against malnutrition and is grappling with the coexistence of undernutrition, overnutrition, and micronutrient deficiencies. This report summarizes discussions on trends in malnutrition in India, its evolution in the context of economic growth, intrahousehold aspects, infant and young child feeding practices, women's status, maternal nutrition, and nutrition policymaking. The discussion focuses on a review of trends in malnutrition and dietary intakes in India in the context of economic change over the past four decades, identification of household dynamics affecting food choices and their consequences for family nutritional status in India, and effective malnutrition prevention and treatment interventions and programs in India and associated policy challenges.

    Poor diet quality is implicated in almost every disease and health issue. And yet, in most advanced market economies diet quality is poor, with a minority meeting guidelines for healthy eating. Poor diet is thus responsible for substantial disease burden. Societies have at their disposal a range of strategies to influence diet behaviors. These can be classified into: (i) population level socio-educational approaches to enhance diet knowledge; (ii) pricing incentives (subsidies on healthy foods, punitive taxes on unhealthy foods); (iii) regulations to modify the food environment, and (iv) the provision of clinical dietetic services. There is little evidence that societies are active in implementing the available strategies. Advertising of “junk foods” is largely unchecked, contrasting with strict controls on advertising tobacco products, which also attract punitive taxes. Access to dieticians is restricted in most countries, even in the context of universal health care. In Australia in 2011 there were just 2,969 practicing dieticians/nutritionists or 1.3 clinicians per 10,000 persons, compared with 5.8 physiotherapists per 10,000 persons, 14.8 general practitioners (family physicians) per 10,000 persons or 75 nurses per 10,000 persons. It is time to implement comprehensive national nutrition strategies capable of effecting change. Such strategies need to be multi-component, incorporating both public health approaches and expanded publicly funded dietetic services. Access to individualized dietetic services is needed by those at risk, or with current chronic conditions, given the complexity of the diet message, the need for professional support for behavior change and to reflect individual circumstances. The adoption of a comprehensive nutrition strategy offers the promise of substantial improvement in diet quality, better health and wellbeing and lower health care costs. PMID:26321951

    Food intolerance is becoming increasingly prevalent, and increasing numbers of athletes have celiac disease. This poses challenges as dietary recommendations for exercise are largely based on gluten-containing carbohydrate-rich foods. The K4 cycle race covers 384 km around the Coromandel Peninsula, New Zealand. Lack of sleep, darkness, and temperature variations pose a number of nutritional challenges. Limited food choices present those with celiac disease with even greater challenges. This case study describes the intakes of one such athlete during training and competing in the K4. Nutritional intakes were obtained during training using weighed-food records and during the race via dietary recall and the weighing of foods pre- and post-race. As simple substitution of gluten-containing foods for gluten-free foods leads to increased energy intake, alternatives need to be considered. During the race, insufficient energy was consumed to meet the nutritional guidelines for endurance performance. This was probably due to the nature of the course, racing conditions, the consistency of gluten-free food, and, toward the end of the race, sensory-specific satiety.

    A growing body of scientific and epidemiological evidence indicates that diet and health are related: diet may be a risk factor or have potential protective effects. As a consequence, the focus of nutrition research has experienced a shift towards qualitative aspects of diet which could influence chronic disease, longevity, quality of life and physical and cognitive performance, leading to the development of Community Nutrition. The main undertakings in a Community Nutrition Unit are related to the identification, assessment and monitoring of nutrition problems at the community level and to planning, design, implementation and evaluation of nutrition intervention programs. Such programs combine a number of suitable strategies in a whole population approach, a high risk approach or an approach targeted at specific population groups, and are implemented in different settings, such as the work place, schools or community organizations. Community nutrition interventions aim to gradually achieve change in eating patterns towards a healthier profile. Community Nutrition programs require the use of a combination of strategies and a working group of people from different backgrounds. Many factors influence the nutritional status of an individual or a population. In order to gain effective work output, sound understanding of these patterns and a practical surveillance system are required.

    In the last 20 years, Public Health Nutrition focused mainly on the qualitative aspects which may influence the onset of chronic diseases, quality of life, physical and mental performance and life expectancy. This applied knowledge organised as part of preventive and health promotion programs led to the development of Community Nutrition. The aim of Community Nutrition actions is to adequate lifestyles related to food consumption patterns in order to improve the quality of life and contribute to health promotion of the population in the community where programs and services are delivered. Key functions to develop in a Community Nutrition Unit consist in the identification and assessment of nutrition problems in the community as well as the design, implementation and evaluation of intervention programs by means of appropriate strategies. These should aim at different populations groups and settings, such as work places, schools, high risk groups or the general public. Nowadays, Community Nutrition work efforts should focus on three main aspects: nutrition education in schools and in the community; food safety and food security and the development and reinforcement of food preparation skills across all age groups. Social catering services, either in schools, the work place or at the community level, need to ensure adequate nutritional supply, provide foods contributing to healthy eating practices as well as to enhance culinary traditions and social learning. Food safety and food security have become a top priority in Public Health. The concepts referes to the availability of food safe and adequate as well as in sufficient amount in order to satisfy nutrition requirements of all individuals in the community. Social changes along new scientific developments will introduce new demands in Community Nutrition work and individual dietary counselling will become a key strategy. In order to face new challenges, community nutrition pactitioners require a high quality

    In 1991-1992, Via Libre, a nongovernmental organization (NGO), developed an information program for the general public in Lima using a portable pavilion. The metallic structure is 32 square meters and houses 30 posters with prevention messages. Collaboration with another NGO, Instituto Generacion, resulted in the production of a 7 minute video of basic information that is shown continuously at the pavilion. Facilitators distribute printed materials. Occasionally, a third NGO, Asociacion Germinal, provides street clowns who carry prevention messages to accompany the exhibit. Due to positive public response, the exhibit became "The Information Traveling Pavilion" in 1993; the exhibit has traveled to more than seven cities throughout Peru. Via Libre staff provide local health workers with information update courses and counseling workshops in order to respond to increased public demands for information and support following the activities. 75 private enterprises have provided support for the program. Radio and television collaborate in publicizing the activities.

    2008-01-01

    This article is the second in a two-part review of law's possible role in a regulatory approach to healthier nutrition and obesity prevention in Australia. As discussed in Part 1, law can intervene in support of obesity prevention at a variety of levels: by engaging with the health care system, by targeting individual behaviours, and by seeking to influence the broader, socio-economic and environmental factors that influence patterns of behaviour across the population. Part 1 argued that the most important opportunities for law lie in seeking to enhance the effectiveness of a population health approach. Part 2 of this article aims to provide a systematic review of the legal strategies that are most likely to emerge, or are worth considering, as part of a suite of policies designed to prevent population weight gain and, more generally, healthier nutrition. While the impact of any one intervention may be modest, their cumulative impact could be significant and could also create the conditions for more effective public education campaigns. This article addresses the key contenders, with particular reference to Australia and the United States. PMID:18533999

    2016-01-01

    Summary In the past couple of decades, evidence from prospective observational studies and clinical trials has converged to support the importance of individual nutrients, foods, and dietary patterns in the prevention and management of type 2 diabetes. The quality of dietary fats and carbohydrates consumed is more crucial than the quantity of these macronutrients. Diets rich in whole grains, fruits, vegetables, legumes, nuts, moderate in alcohol consumption, and lower in refined grains, red/processed meats, and sugar-sweetened beverages have demonstrated to reduce diabetes risk and improve glycemic control and blood lipids in patients with diabetes. Several healthful dietary patterns emphasizing the overall diet quality can be adapted to appropriate personal and cultural food preferences and calorie needs for weight control and diabetes prevention and management. Although considerable progress has been made in developing and implementing evidence-based nutrition recommendations in developed countries, concerted global efforts and policies are warranted to alleviate regional disparities.

    Dairy farm activities contribute to environmental pollution through the surplus N and P that they produce. Optimization of animal feeding and management has been described as a key strategy for decreasing N and P excretion in manure. Sixty-four commercial dairy farms were studied to assess the efficiency of N and P use in lactating herds and to identify dietary and management factors that may contribute to improving the efficiency of nutrient use for milk production, and decrease N and P excretion. The average ration was formulated to 50:50 forage:concentrate ratio with grass silage and corn silage as the main forage sources. Mean N and P intakes were 562 g/d [16.4% crude protein (CP)] and 84.8 g/d (0.40% P), respectively. Milk yield averaged 29.7 kg/d and contributed to 25.8% (standard deviation +/- 2.9) of N utilization efficiency (NUE) and 31.9% (standard deviation +/- 4.5) of P utilization efficiency (PUE). Dietary N manipulation through fitting the intake of CP to animal requirements showed a better response in terms of decreasing N excretion (R(2) = 0.70) than that estimated for P nutrition and excretion (R(2) = 0.30). Improvement in NUE helped increase PUE, despite the widespread use of feedstuffs with a high P content. Management strategies for lactating herds, such as the use of different feeding groups, periodical ration reformulation, and selection of feeding system did not show any consistent response in terms of improved NUE and PUE. The optimization of NUE and PUE contributed to decreasing the N and P excretion per unit of milk produced, and therefore, reductions in N and P excretion of between 17 and 35%, respectively, were estimated. Nevertheless, nutritional and herd management strategies were limited when N and P excretion were considered in relation to the whole lactating herd and farmland availability. Dietary CP manipulation was estimated to decrease herd N excretion by 11% per hectare, whereas dietary P manipulation would be decreased by no

    2013-01-01

    Background Syphilis is an important sexually transmitted infection (STI) with serious public health consequences. Among men who have sex with men (MSM) in Lima, the prevalence and incidence are extraordinarily high. Current syndromic approaches, however, fail to identify asymptomatic cases, and in settings where large proportions of individuals test positive again after treatment, it is frequently difficult to distinguish treatment failure from re-infection. Thus, new approaches are needed to improve treatment strategies and public health control efforts. Methods/Design Study participants will undergo baseline testing for syphilis infection along with a behavioral survey covering demographics, sexual behavior, drug and alcohol abuse and health-care seeking behavior. The cohort will be followed for 18 months at three-month intervals. Blood and earlobe scrapings will also be collected for T. pallidum DNA testing, to create molecular markers for subtyping. We will also perform cytokine testing on collected samples in order to create host immunologic profiles associated with recurrence, re-infection, treatment failure and success. Discussion Advances in social epidemiology, molecular typing and characterization of host immune responses will offer promise in developing new understandings of syphilis management. We will share our findings with the Peruvian Ministry of Health and other public health organizations, to identify new approaches of case detection and successful treatment. PMID:24016185

    The Nasca Lines are located in the Pampa region of Peru, the desolate plain of the Peruvian coast 400 km south of Lima. The Lines were first spotted when commercial airlines began flying across the Peruvian desert in the 1920's. Passengers reported seeing 'primitive landing strips' on the ground below. The Lines were made by removing the iron-oxide coated pebbles which cover the surface of the desert. When the gravel is removed, they contrast with the light color underneath. In this way the lines were drawn as furrows of a lighter color. On the pampa, south of the Nasca Lines, archaeologists have now uncovered the lost city of the line-builders, Cahuachi. It was built nearly two thousand years ago and was mysteriously abandoned 500 years later. This ASTER sub-image covers an area of 14 x 18 km, was acquired on December 22, 2000, and is located at 14.7 degrees south latitude and 75.1 degrees west longitude.

    The performance of female calves in creep feeding under different strategies of supplementation and milk production, intake, and digestibility of grazing Nellore and crossbred cows (Nellore × Holstein) during the dry-rainy transition season were assessed. Forty-four female beef suckling calves, with initial age between 90 and 150 days and average initial body weight of 117.7 ± 4.3 kg, and their respective dams (24 Nellore and 20 crossbred) with average initial body weight of 417.5 ± 8.3 kg, were used. The experimental treatments consisted of: control group--mineral mixture only; strategy 1--supplementation from 112 days prior to weaning (0.375 kg/animal/day); strategy 2--supplementation from 112 days prior to weaning, in increasing amounts of 0.15, 0.30, 0.45, and 0.60 kg/animal/day through the four experimental periods, respectively; and strategy 3--supplementation from 56 days prior to weaning (0.750 kg/animal/day). Calves from strategy 1 had greater (P < 0.05) average daily gain (0.672 kg/day) than control animals (0.582 kg/day) and greater (P < 0.05) efficiency of supplement use than the other groups. Crossbred cows produced more milk than Nellore cows (P < 0.05). Crossbred cows presented greater (P < 0.05) dry matter intake (DMI) than Nellore cows. However, no differences were found (P > 0.05) for nutrient digestibility among genetic types. It can be concluded that strategies of supplementation that present an equitable distribution of supplement provides greater weight gain in suckling female beef calves. Crossbred cows produce more milk and present greater DMI than Nellore cows. There are no differences in the nutrient digestibility between Nellore and Nellore × Holstein crossbred cows.

    The Supplemental Nutrition Assistance Program (SNAP), the largest federal food assistance program, currently serves 44.7 million Americans with a budget of $75 billion in 2011. This study engaged leading experts for in-depth, semi-structured interviews to explore their opinions concerning the existing challenges and barriers to eating nutritiously in SNAP. Experts also proposed strategies for improving nutritional status among SNAP recipients. Twenty-seven individuals were interviewed from advocacy, government, industry, and research organizations. Interviews were recorded, transcribed, coded, and analyzed for thematic content. The high cost of nutrient-rich foods, inadequate SNAP benefits, limited access to purchasing healthy foods, and environmental factors associated with poverty were identified as barriers that influence nutrition among low-income households in the United States. Six themes emerged among respondents from diverse sectors about how to address these challenges, including providing SNAP participants with incentives to purchase nutrient-rich food consistent with the 2010 Dietary Guidelines for Americans, restricting the purchase of nutrient-poor foods and beverages with program benefits, modifying the frequency of SNAP benefit distribution, enhancing nutrition education, improving the SNAP retailer environment, and increasing state and federal level coordination and consistency of program implementation. Given the recent dramatic increase in SNAP enrollment, policymakers must address existing barriers as well as consider new strategies to improve nutrition policies in SNAP so that the program can continue to address food insecurity needs as well as provide a healthful diet for SNAP beneficiaries.

  7. Could the 3D Printing Technology be a Useful Strategy to Obtain Customized Nutrition?

    PubMed

    Severini, Carla; Derossi, Antonio

    Within the concept of personalized nutrition we want to introduce the terms of "customized food formula" which refers to the preparation (at home) or the production (at industrial level) of new food formulations having nutrients and functional compounds necessary to prevent diseases or to reduce the risk for each subject (or subjects category) who exhibit a susceptibility to diseases. Three-dimensional (3D) printing is a group of technologies of growing interest able to produce, slice by slice, materials with any desired shape, dimension, and structure properties. The application of 3D printing in food science, as called "3D food printing," is a pioneering technology that could allow to build personalized foods by depositing nutrients and functional compounds or soft-materials obtained by their mixture. Also by 3D food printing it is expected to obtain personalized food formula having desired shape, dimension, and microstructure. This would be useful for people having swallowing problems. In this paper we analyzed the first examples of 3D food printing available in literature as well as we reported our results focused on the production of 3D printed wheat-based snacks enriched with insect powder (Tenebrio molitor) with the aim to improve the quality and the content of proteins.

    Fostering interaction in the online classroom is an important consideration in ensuring that students actively create their own knowledge and reach a high level of achievement in science courses. This study focuses on fostering interaction in an online introductory nutrition course offered in a public institution of higher education in Hawai'i, USA. Interactive features included synchronous discussions and polls in scheduled sessions, and social media tools for sharing of information and resources. Qualitative student feedback was solicited regarding the new course features. Findings indicated that students who attended monthly synchronous sessions valued live interaction with peers and the instructor. Issues identified included technical difficulties during synchronous sessions, lack of participation on the part of fellow students in discussion and inability to attend synchronous sessions due to scheduling conflicts. In addition, few students made use of the opportunity to interact via social media. While students indicated that the interactive components of the course were valuable, several areas in which improvement may be made remain. Future studies may explore potential solutions to issues identified with new features to further promote interaction and foster learning in the course. Recommendations for instructors who are interested in offering online science courses in higher education are provided.

    2016-01-01

    Summary The gut microbiota is a dense and diverse microbial community governed by dynamic microbe–microbe and microbe–host interactions, the status of which influences whether enteric pathogens can cause disease. Here we review recent insights into the key roles that nutrients play in bacterial pathogen exploitation of the gut microbial ecosystem. We synthesize recent findings to support a five-stage model describing the transition between a healthy microbiota and one dominated by a pathogen and disease. Within this five-stage model, two stages are critical to the pathogen: (i) an initial expansion phase that must occur in the absence of pathogen-induced inflammation, followed by (ii) pathogen-promoting physiological changes such as inflammation and diarrhoea. We discuss how this emerging paradigm of pathogen life within the lumen of the gut is giving rise to novel therapeutic strategies. PMID:24720567

    Astronauts face numerous health challenges during long-duration space missions, including diminished immunity, bone loss and increased risk of radiation-induced carcinogenesis. Changes in the intestinal flora of astronauts may contribute to these problems. Soy-based fermented food products could provide a nutritional strategy to help alleviate these challenges by incorporating beneficial lactic acid bacteria, while reaping the benefits of soy isoflavones. We carried out strain selection for the development of soy ferments, selecting strains of lactic acid bacteria showing the most effective growth and fermentation ability in soy milk ( Streptococcus thermophilus ST5, Bifidobacterium longum R0175 and Lactobacillus helveticus R0052). Immunomodulatory bioactivity of selected ferments was assessed using an in vitro challenge system with human intestinal epithelial and macrophage cell lines, and selected ferments show the ability to down-regulate production of the pro-inflammatory cytokine interleukin-8 following challenge with tumour necrosis factor-alpha. The impact of fermentation on vitamin B1 and B6 levels and on isoflavone biotransformation to agluconic forms was also assessed, with strain variation-dependent biotransformation ability detected. Overall this suggests that probiotic bacteria can be successfully utilized to develop soy-based fermented products targeted against health problems associated with long-term space travel.

    Obesity and associated chronic inflammation initiate a state of insulin resistance (IR). The secretion of chemoattractants such as MCP-1 and MIF and of cytokines IL-6, TNF-α, and IL-1β, draw immune cells including dendritic cells, T cells, and macrophages into adipose tissue (AT). Dysfunctional AT lipid metabolism leads to increased circulating free fatty acids, initiating inflammatory signaling cascades in the population of infiltrating cells. A feedback loop of pro-inflammatory cytokines exacerbates this pathological state, driving further immune cell infiltration and cytokine secretion and disrupts the insulin signaling cascade. Disruption of normal AT function is causative of defects in hepatic and skeletal muscle glucose homeostasis, resulting in systemic IR and ultimately the development of type 2 diabetes. Pharmaceutical strategies that target the inflammatory milieu may have some potential; however there are a number of safety concerns surrounding such pharmaceutical approaches. Nutritional anti-inflammatory interventions could offer a more suitable long-term alternative; whilst they may be less potent than some pharmaceutical anti-inflammatory agents, this may be advantageous for long-term therapy. This review will investigate obese AT biology, initiation of the inflammatory, and insulin resistant environment; and the mechanisms through which dietary anti-inflammatory components/functional nutrients may be beneficial.

    Inflammatory bowel disease (IBD) is a group of chronic, lifelong, and relapsing illnesses, such as ulcerative colitis and Crohn's disease, which involve the gastrointestinal tract. There is no cure for these diseases, but combined pharmacological and nutritional therapy can induce remission and maintain clinical remission. Malnutrition and nutritional deficiencies among IBD patients result in poor clinical outcomes such as growth failure, reduced response to pharmacotherapy, increased risk for sepsis, and mortality. The aim of this review is to highlight the consequences of malnutrition in the management of IBD and describe nutritional interventions to facilitate induction of remission as well as maintenance; we will also discuss alternative delivery methods to improve nutritional status preoperatively.

    Background/objectives: Sodium intake in the Netherlands is substantially above the recommended intake of 2400 mg/day. This study aimed to estimate the effect of two sodium reduction strategies, that is, modification of the composition of industrially processed foods toward the technologically feasible minimum level or alteration of consumers' behavior on sodium intake in the Netherlands. Subjects/methods: Data from the Dutch National Food Consumption Survey (2007–2010) and the Food Composition Table (2011) were used to estimate the current sodium intake. In the first scenario, levels in processed foods were reduced toward their technologically feasible minimum level (sodium reduction in processed foods scenario). The minimum feasible levels were based on literature searches or expert judgment. In the second scenario, foods consumed were divided into similar food (sub)groups. Subsequently, foods were replaced by low-sodium alternatives (substitution of processed foods scenario). Sodium intake from foods was calculated based on the mean of two observation days for the current food consumption pattern and the scenarios. Results: Sodium levels of processed foods could be reduced in most food groups by 50%, and this may reduce median sodium intake from foods by 38% (from 3042 to 1886 mg/day in adult men). Substitution of foods may reduce sodium intake by 47% (from 3042 to 1627 mg/day in adult men), owing to many low-sodium alternatives within food groups. Conclusions: In the Netherlands, reduction of sodium intake by modification of food composition or by alteration of behavior may substantially reduce the median sodium intake from foods below the recommended sodium intake.

    Revival of Peru's moribund oil and gas industry in the 1990s hinges on whether the new administration of President Alberto Fujimori is successful in attracting foreign investment in Peru. Fujimori's success would mean Peru pushing ahead into stepped up exploration and major development projects, such as the huge Camisea gas/condensate field discovered 2 years ago. His failure could mean Peru continuing to fall further behind in its already lagging low oil production. Huge sums of money will be needed. Peru also needs to succeed in its efforts to become creditworthy again for international agencies, foreign governments, and commercial banks. Meanwhile, Petroleos del Peru SA (Petroperu), the state oil company, will have to transfer an increasing share of its operations to private investors. But the company is likely to try to hold onto producing fields, even though it is unable to maintain full output.

    Global recommendations on strategies to improve infant feeding, care and nutrition are clear; however, there is limited literature that explains methods for tailoring these recommendations to the local context where programmes are implemented. This paper aims to: (1) highlight the individual, cultural and environmental factors revealed by formative research to affect infant and young child feeding and care practices in Baitadi district of Far Western Nepal; and (2) outline how both quantitative and qualitative research methods were used to design a context-specific behaviour change strategy to improve child nutrition. Quantitative data on 750 children aged 12-23 months and their families were collected via surveys administered to mothers. The participants were selected using a multistage cluster sampling technique. The survey asked about knowledge, attitude and behaviours relating to infant and young child feeding. Qualitative data on breastfeeding and complementary feeding beliefs and practices were also collected from a separate sample via focus group discussions with mothers, and key informant interviews with mothers-in-law and husbands. Key findings revealed gaps in knowledge among many informants resulting in suboptimal infant and young child feeding practices - particularly with relation to duration of exclusive breastfeeding and dietary diversity of complementary foods. The findings from this research were then incorporated into a context-specific nutrition behaviour change communication strategy.

    Introduction As a group, transwomen in Peru have the highest prevalence of HIV (>20%) in the country, but they have little access to HIV prevention, testing and care services. Until recently, Peru's national HIV programme did not recognize transwomen and had remained essentially static for decades. This changed in December 2014, when the Ministry of Health expressed its commitment to improve programming for transwomen and to involve transwomen organizations by prioritizing the development of a “Targeted Strategy Plan of STIs/HIV/AIDS Prevention and Comprehensive Care for Transwomen.” Discussion A policy dialogue between key stakeholders – Peru's Ministry of Health, academic scientists, civil society, transgender leaders and international agencies – created the conditions for a change in Peru's national HIV policy for transwomen. Supported by the effective engagement of all sectors, the Ministry of Health launched a plan to provide comprehensive HIV prevention and care for transwomen. The five-year plan includes new national guidelines for HIV prevention, care and support, and country-level investments in infrastructure and equipment. In addition to new biomedical strategies, the plan also incorporates several strategies to address structural factors that contribute to the vulnerability of transwomen. We identified three key factors that created the right conditions for this change in Peru's HIV policy. These factors include (1) the availability of solid evidence, based on scientific research; (2) ongoing efforts within the transwomen community to become better advocates of their own rights; and (3) a dialogue involving honest discussions between stakeholders about possibilities of changing the nation's HIV policy. Conclusions The creation of Peru's national plan for HIV prevention and care for transwomen shows that long-term processes, focused on human rights for transwomen in Peru, can lead to organizational and public-policy change.

    The purpose of the study was to evaluate the effectiveness of a multicomponent nutrition education program among adults. A pretest—posttest design was used assessing Nutritional Knowledge (NK), BMI, Energy Intake (EI), Physical Activity Level (PAL), Dietary Intake (DI) and attitudes. 353 adults aged 19–55 years (178 control group (CG) and 175 intervention group (IG)) were recruited. IG participants attended nutrition education sessions evaluated through a post-test given at the end of the 12-week program. Statistical tests performed revealed that compared to CG, participants in IG increased fruit intake and decreased intake of snacks high in sugar and fat significantly (p < 0.05). NK and attitudinal scores also increased significantly in the IG (p < 0.05). No intervention effect was found for vegetables intake, EI, BMI and PAL (p > 0.05). Factors influencing NK were age, gender and education level. “Taste” was the main barrier to the application of the nutrition education strategy. Findings are helpful to health practitioners in designing their intervention programs. PMID:26938555

    Introduction Residents of rural communities in the United States are at higher risk for obesity than their urban and suburban counterparts. Policy and environmental-change strategies supporting healthier dietary intake can prevent obesity and promote health equity. Evidence in support of these strategies is based largely on urban and suburban studies; little is known about use of these strategies in rural communities. The purpose of this review was to synthesize available evidence on the adaptation, implementation, and effectiveness of policy and environmental obesity-prevention strategies in rural settings. Methods The review was guided by a list of Centers for Disease Control and Prevention Recommended Community Strategies and Measurements to Prevent Obesity in the United States, commonly known as the “COCOMO” strategies. We searched PubMed, Cumulative Index of Nursing and Allied Health Literature, Public Affairs Information Service, and Cochrane databases for articles published from 2002 through 2013 that reported findings from research on nutrition-related policy and environmental strategies in rural communities in the United States and Canada. Two researchers independently abstracted data from each article, and resolved discrepancies by consensus. Results Of the 663 articles retrieved, 33 met inclusion criteria. The interventions most commonly focused on increasing access to more nutritious foods and beverages or decreasing access to less nutritious options. Rural adaptations included accommodating distance to food sources, tailoring to local food cultures, and building community partnerships. Conclusions Findings from this literature review provide guidance on adapting and implementing policy and environmental strategies in rural communities. PMID:25927605

    Food insecurity, micronutrient deficits, dyslipidemia, insulin resistance, obesity, cardiovascular disease, and bone disorders complicate the treatment of HIV infection. Nutrition and exercise interventions can be effective in ameliorating these symptoms that are associated with HIV and antiretroviral therapy (ART). In this literature review, we examine the most recent nutrition and exercise interventions for HIV-infected patients. Macronutrient supplementation can be useful in treating malnutrition and wasting. Multivitamin (vitamin B complex, vitamin C, and vitamin E) supplements and vitamin D may improve quality of life and decrease morbidity and mortality. Nutritional counseling and exercise interventions are effective for treating obesity, fat redistribution, and metabolic abnormalities. Physical activity interventions improve body composition, strength, and fitness in HIV-infected individuals. Taken collectively, the evidence suggests that a proactive approach to nutrition and physical activity guidance and interventions can improve outcomes and help abrogate the adverse metabolic, cardiovascular, and psychological consequences of HIV and its treatments.

    The aim of this project was to collect data from focus-group participants to inform the future development of region-specific educational strategies to modify infant-feeding practices that may predispose children to obesity. Infant-feeding perceptions and practices were collected from participants of the Special Supplemental Nutrition Program for Women, Infants, and Children, through recorded focus groups, in two East Tennessee counties. Focus groups replaced the participants' required, prescheduled nutrition-education classes for participants with infants younger than 6 months of age. Twenty-nine focus groups were convened and recorded, reaching a total of 109 participants. Results of this series of focus groups indicate that the Special Supplemental Nutrition Program for Women, Infants, and Children population in rural East Tennessee was similar to populations elsewhere in terms of early solid-food introduction, frequent switching of formula, and sources of and valuation of infant-feeding advice. However, this population seemed to be different in the magnitude at which they introduce infant cereal early (primarily as an addition to the bottle). For this reason, interventions designed to reduce inappropriate infant-feeding behaviors in this population should focus on early introduction of solid food (especially infant cereal) first. In addition to these findings, a model of infant-feeding strategy development based on caregiver-orientation (framed within parenting styles) is presented and discussed.

    Epidemiological data about mycotic diseases are limited in Peru and estimation of the fungal burden has not been previously attempted. Data were obtained from the Peruvian National Institute of Statistics and Informatics, UNAIDS and from the Ministry of Health's publications. We also searched the bibliography for Peruvian data on mycotic diseases, asthma, COPD, cancer and transplants. Incidence or prevalence for each fungal disease were estimated in specific populations at risk. The Peruvian population for 2015 was 31,151,543. In 2014, the estimated number of HIV/AIDS and pulmonary tuberculosis cases was 88,625, 38,581 of them not on ART, and 22,027, respectively. A total of 581,174 cases of fungal diseases were estimated, representing approximately 1.9% of the Peruvian population. This figure includes 498,606, 17,361 and 4,431 vulvovaginal, oral and esophageal candidiasis, respectively, 1,557 candidemia cases, 3,593 CPA, 1,621 invasive aspergillosis, 22,453 allergic bronchopulmonary aspergilllosis, 29,638 severe asthma with fungal sensitization, and 1,447 Pneumocystis pneumonia. This first attempt to assess the fungal burden in Peru needs to be refined. We believe the figure obtained is an underestimation, because of under diagnosis, non-mandatory reporting and lack of a surveillance system and of good data about the size of populations at risk.

    Natural abundance stable-isotope analysis (δ(13)C and δ(15)N) and C:N ratios were used to study the ammocoete phase of two common non-parasitic lamprey species (least brook lamprey Lampetra aepyptera and American brook lamprey Lethenteron appendix) in two tributaries of the Ohio River (U.S.A.). The C:N ratios suggest that each species employs different lipid accumulation strategies to support its metamorphosis and recruitment into an adult animal. Ammocoete δ(13)C values generally increased with increasing C:N values. In contrast to δ(13)C, ammocoete δ(15)N values were weakly related to the total length (LT) in L. aepyptera, but positively correlated to both LT and C:N ratios in L. appendix. In L. appendix, C:N also correlated positively with LT, and presumably age. A Bayesian mixing model using δ(13)C and δ(15)N was used to estimate nutritional subsidies of different potential food resources to ammocoetes at each site. The models suggested that although nutritional subsidies to ammocoetes varied as a function of site, ammocoetes were generally reliant on large contributions (42-62% at three sites) from aquatic plants. Contributions from aquatic sediment organic matter were also important at all sites (32-63%) for ammocoetes, with terrestrially derived plant materials contributing smaller amounts (4-33%). These findings provide important insights into the feeding ecology and nutrition of two species of lampreys. They also suggest that similar and other quantitative approaches are required to (1) fully understand how the observed stable-isotopes ratios are established in ammocoetes and (2) better assess ammocoete nutritional subsidies in different natal streams.

    The Pediatric Gastroenterology and Nutrition in Peru, is one of the subspecialties of Pediatrics that has experienced one of the most significant growth in recent decades, however, to achieve this seat it should have passed a long way built through the efforts and talent hundreds of doctors for several generations. Its modern history began in 1981 with the creation of the first unit of the specialty in the National Institute of Child Health (INSN), followed by the establishment of the second specialization that contributed to its spread and progress of several hospitals in the country, and many of them now have a doctor of this specialty. Our purpose is to plant the foundations of that story, whose extension go beyond the space that allows us an article.

    The nuclear factor E2-related factor 2 (Nrf2) plays an important role in cellular protection against cancer, renal, pulmonary, cardiovascular and neurodegenerative diseases where oxidative stress and inflammation are common conditions. The Nrf2 regulates the expression of detoxifying enzymes by recognizing the human Antioxidant Response Element (ARE) binding site and it can regulate antioxidant and anti-inflammatory cellular responses, playing an important protective role on the development of the diseases. Studies designed to investigate how effective Nrf2 activators or modulators are need to be initiated. Several recent studies have shown that nutritional compounds can modulate the activation of Nrf2-Keap1 system. This review aims to discuss some of the key nutritional compounds that promote the activation of Nrf2, which may have impact on the human health.

    Background Since 2010, federal and local agencies have invested broadly in a variety of nutrition-focused policy, systems and environmental change (PSE) initiatives in Los Angeles County (LAC). To date, little is known about whether the public supports such efforts. We address this gap in the literature by examining predictors of support for a variety of PSEs. Methods Voters residing in LAC (n=1007) were randomly selected to participate in a cross-sectional telephone survey commissioned by the LAC Department of Public Health. The survey asked questions about attitudes towards the obesity epidemic, nutrition knowledge and behaviours, public opinions about changing business practices/government policies related to nutrition, and sociodemographics. A factor analysis informed outcome variable selection (ie, type of PSEs). Multivariable regression analyses were performed to examine predictors of public support. Predictors in the regression models included (primary regressor) community economic hardship; (control variables) political affiliation, sex, age, race and income; and (independent variables) perceptions about obesity, perceived health and weight status, frequency reading nutrition labels, ease of finding healthy and unhealthy foods, and food consumption behaviours (ie, fruit and vegetables, non-diet soda, fast-food and sit-down restaurant meals). Results 3 types of PSE outcome variables were identified: promotional/incentivising, limiting/restrictive and business practices. Community economic hardship was not found to be a significant predictor of public support for any of the 3 PSE types. However, Republican party affiliation, being female and perceiving obesity as a serious health problem were. Conclusions These findings have implications for public health practice and community planning in local health jurisdictions. PMID:28087545

    BACKGROUND Taeniasis and cysticercosis are major causes of seizures and epilepsy. Infection by the causative parasite Taenia solium requires transmission between humans and pigs. The disease is considered to be eradicable, but data on attempts at regional elimination are lacking. We conducted a three-phase control program in Tumbes, Peru, to determine whether regional elimination would be feasible. METHODS We systematically tested and compared elimination strategies to show the feasibility of interrupting the transmission of T. solium infection in a region of highly endemic disease in Peru. In phase 1, we assessed the effectiveness and feasibility of six intervention strategies that involved screening of humans and pigs, antiparasitic treatment, prevention education, and pig replacement in 42 villages. In phase 2, we compared mass treatment with mass screening (each either with or without vaccination of pigs) in 17 villages. In phase 3, we implemented the final strategy of mass treatment of humans along with the mass treatment and vaccination of pigs in the entire rural region of Tumbes (107 villages comprising 81,170 people and 55,638 pigs). The effect of the intervention was measured after phases 2 and 3 with the use of detailed necropsy to detect pigs with live, nondegenerated cysts capable of causing new infection. The necropsy sampling was weighted in that we preferentially included more samples from seropositive pigs than from seronegative pigs. RESULTS Only two of the strategies implemented in phase 1 resulted in limited control over the transmission of T. solium infection, which highlighted the need to intensify the subsequent strategies. After the strategies in phase 2 were implemented, no cyst that was capable of further transmission of T. solium infection was found among 658 sampled pigs. One year later, without further intervention, 7 of 310 sampled pigs had live, nondegenerated cysts, but no infected pig was found in 11 of 17 villages, including all

    In order to test the sensitivity and specificity of the East Orange Nutritional Screening Form (EONSF), nutritional assessments were performed on a random sample of 10% of general medical/surgical admissions at a large midwestern veteran's administration hospital. Patients were followed until discharge to determine if they met the standard criteria of additional nutritional support. The tool correctly identified patients at nutritional risk (sensitivity) 95% of the time and patients not at nutritional risk (specificity) 89% of the time. It proved to be an effective, low-cost tool for identifying patients at risk and for planning appropriate nutritional strategies.

    Alzheimer's disease (AD) is characterized by dysfunctional intracellular and extracellular biochemical processes that result in neuron death. This article summarizes hypotheses regarding cell dysfunction in AD and discusses the effectiveness of, and problems with, different therapies. Pharmaceutical therapies discussed include cholinesterase inhibitors, memantine, antihypertensive drugs, anti-inflammatory drugs, secretase inhibitors, insulin resistance drugs, etanercept, brain-derived neurotrophic factor, and immunization. Nutritional and botanical therapies included are huperzine A, polyphenols, Ginkgo, Panax ginseng, Withania somnifera, phosphatidylserine, alpha-lipoic acid, omega-3 fatty acids, acetyl L-carnitine, coenzyme Q10, various vitamins and minerals, and melatonin. Stimulatory therapies discussed are physical exercise, cognitive training, music, and socialization. Finally, treatment strategies are discussed in light of the benefits and drawbacks of different therapeutic approaches. It is concluded that potential risks of both approved and non-approved therapies should be weighed against the potential benefits and certain consequences of disease progression. Approaches that target several dysfunctions simultaneously and that emphasize nutritional, botanical, and stimulatory therapies may offer the most benefit at this time.

  5. Camana, Peru, and Tsunami Vulnerability

    A tsunami washed over the low-lying coastal resort region near Camana, southern Peru, following a strong earthquake on June 23, 2001. The earthquake was one of the most powerful of the last 35 years and had a magnitude of 8.4. After the initial quake, coastal residents witnessed a sudden drawdown of the ocean and knew a tsunami was imminent. They had less than 20 minutes to reach higher ground before the tsunami hit. Waves as high as 8 m came in four destructive surges reaching as far as 1.2 km inland. The dashed line marks the approximate area of tsunami inundation. Thousands of buildings were destroyed, and the combined earthquake and tsunami killed as many as 139 people. This image (ISS004-ESC-6128) was taken by astronauts onboard the International Space Station on 10 January 2002. It shows some of the reasons that the Camana area was so vulnerable to tsunami damage. The area has a 1 km band of coastal plain that is less than 5 m in elevation. Much of the plain can be seen by the bright green fields of irrigated agriculture that contrast with the light-colored desert high ground. Many of the tsunami-related deaths were workers in the onion fields in the coastal plain that were unwilling to leave their jobs before the end of the shift. A number of lives were spared because the tsunami occurred during the resort off-season, during the daylight when people could see the ocean drawdown, and during one of the lowest tides of the year. Information on the Tsunami that hit Camana can be found in a reports on the visit by the International Tsunami Survey Team and the USC Tsunami Research Lab. Earthquake Epicenter, Peru shows another image of the area. Image provided by the Earth Sciences and Image Analysis Laboratory at Johnson Space Center. Additional images taken by astronauts and cosmonauts can be viewed at the NASA-JSC Gateway to Astronaut Photography of Earth.

It follows that the combination of different institutional mechanisms favors intersectorality, such as: the existence and location of councils integrated by government sectors and civil society in the presidency; political support by the presidency and inclusion of the issue as being strategic in the governmental agenda; assembly of institutional spaces that articulate the highest government spheres and that integrate technical levels; programs that integrate food production, commercialization, and consumption. Challenges concern interrelation with economic policy and the construction of budget agreed among sectors, integrated to policy management and monitoring.

  7. Physician nutrition education.

    Nutrition education for physicians in the United States is limited in scope, quality, and duration due to a variety of factors. As new data and quality improvement initiatives highlight the importance of nutrition and a generation of nutrition experts retire, there is a need for new physician educators and leaders in clinical nutrition. Traditional nutrition fellowships and increased didactic lecture time in school and postgraduate training are not feasible strategies to develop the next generation of physician nutrition specialists in the current environment. One strategy is the development of short immersion courses for advanced trainees and junior attendings. The most promising courses include a combination of close mentorship and adult learning techniques such as lectures, clinical experiences, literature review, curricular development, research and writing, multidisciplinary interactions, and extensive group discussion. These courses also allow the opportunity for advanced discourse, development of long-term collaborative relationships, and continued longitudinal career development for alumni after the course ends. Despite these curricular developments, ultimately the field of nutrition will not mature until the American Board of Medical Specialties recognizes nutrition medicine with specialty board certification.

    Human infection by leptospires has highly variable clinical manifestations, which range from subclinical infection to fulminant disease. We conducted a population-based, cross-sectional seroepidemiologic study in Peru to determine potential relationships of environmental context to human exposure to Leptospira and disease associated with seroconversion. Three areas were studied: a flooded, urban slum in the Peruvian Amazon city of Iquitos; rural, peri-Iquitos villages; and a desert shantytown near Lima. Seroprevalence in Belen was 28% (182/650); in rural areas, 17% (52/316); and in a desert shantytown, 0.7% (1/150). Leptospira-infected peridomestic rats were found in all locales. In Belen, 20 (12.4%) of 161 patients seroconverted between dry and wet seasons (an incidence rate of 288/1,000). Seroconversion was associated with history of febrile illness; severe leptospirosis was not seen. Human exposure to Leptospira in the Iquitos region is high, likely related both to the ubiquity of leptospires in the environment and human behavior conducive to transmission from infected zoonotic sources.

  10. Risk of aspiration in patients on enteral nutrition: frequency, relevance, relation to pneumonia, risk factors, and strategies for risk reduction.

    2007-08-01

    Upper digestive feeding intolerance, as evidenced by high gastric residual volume and vomiting, is the most common complication among hospitalized patients receiving enteral nutrition. These patients are at high risk of developing aspiration pneumonia, which in turn is associated with prolonged hospital stay and increased mortality. Most episodes of aspiration are small in volume and do not lead to pneumonia. The likelihood of pneumonia increases with multiple aspirations. Pneumonia is also more common in critically ill patients who have bacterial colonization of the oropharynx. Gastric residual volume is commonly used as a means to assess aspiration risk during tube feeding. However, recent studies have demonstrated that this measurement has limited sensitivity. The approach to minimizing the frequency of aspiration during tube feeding involves assessment of the patient's degree of risk and initiation of appropriate measures directed at risk reduction.

    This study examines the performance of dietitians-in-training on developing a diet plan for a diabetic patient either independently or after peer discussion. Participants (n = 58) from an undergraduate program in food and nutrition were divided into two groups based on their prior knowledge before being randomly assigned into three conditions: (1) peer discussion with just-in-time information (JIT information), (2) peer discussion without JIT information), and (3) independent performers. The learners' performance in the three conditions was analyzed. The results presented here describe the role of prior knowledge and JIT information across the conditions and the interaction of the two factors as well as the instructional implications of the findings.

    2003-01-01

    An inquiry into options for Masters-level training and into attitudes and perceptions among a convenience sample of nutrition students and professionals from 11 countries suggests that the term, "Public Health Nutrition", as such, is poorly represented and poorly understood in the Latin American region. At least six countries (Brazil, Chile, Cuba, Mexico, Peru, Puerto Rico) at seven sites have Masters programs to provide training for nutrition in a public health context or public health with an emphasis in nutrition. Exploring alliances from the Americas with the formal PHN discipline emerging in Europe should enrich the mutual perspective on curriculum design. However, the form and context of postgraduate training in Latin America must consider first and foremost its own job-markets, diverse public health needs, and resource allocations in building or transforming training programs.

    Peru is a country located on the Pacific coast of South America with a population of more than 30 million inhabitants. In the past 10 years, Peru has had a steady economic growth. Peru is predominantly an extractive industry country, but the manufacturing and construction sectors are booming. It is in this context that regulations have been implemented to protect the safety and health of workers. One of the most important regulations is the Law on Safety and Health at Work, which has been recently promulgated. Regulations are complemented by training and education in occupational safety and health. The measures are yet to be fully implemented thus a positive effect in reducing accidents and occupational diseases at work has not yet been seen.

  14. Peru action simmering despite privatization delays

    1995-08-07

    After months of delays, the sale of Petroleos del Peru SA (Petroperu) was postponed earlier this year until after the elections, which saw Peru`s incumbent President Alberto Fujimori reelected. In June, Fujimori appointed Amado Yataco Minister of Energy and Mines. Yataco, also serving as president of the privatization commission Copri, said a decision on the sale of Petroperu would be made quickly, perhaps by July 28, ahead of this report`s presstime. The uncertain status of Petroperu has not, however, slowed activity in Peru`s petroleum sector. The paper first discusses privatization plans and Petroperu`s budget, then describes exploration and development activities in the supergiant Camisea gas/condensate fields in the central southern jungle. Activities in several smaller fields are briefly described.

    Neurocysticercosis, the infection of the human central nervous system by the larval stage of the cestode Taenia solium, is an important cause of epilepsy and other neurological manifestations in Peru and most developing countries. Since 1987, the Cysticercosis Working Group in Peru has performed a series of epidemiological studies which led to estimate the impact and to better understand the transmission of Taenia solium. This information was later applied to the design and execution of a control program in Tumbes, in the Northern Coast of Peru. This paper reviews the main epidemiological findings, as well as the conceptual framework of the elimination program and the tools used. Advances in the control of taeniasis/cysticercosis in our country open the road towards its elimination and potential eradication.

    Northern Peru has an exceptionally rich archaeological heritage that includes metalwork, ceramics and textiles. The success of at least a half-dozen pre-Columbian societies dating back 3,000 years and subsequent Spanish colonization in the 1400s has rested on the effective use of northern Peru's abundant resources. In the summer of 2000, my son Matt and I learned about that connection firsthand by volunteering at the Santa Rita B archaeological site in the Chao Valley near Trujillo in northern Peru. Riding donkey-back through the Andes and talking with local people, we got our hands dirty in the rich archaeology and geology of the area. We were able to correlate mineral occurrences to their various roles in society - opening a window into the region's fascinating past. From construction to metallurgy, pre-Columbian societies flourished and advanced because of their understanding and use of the available mineral resources.

    Objectives The primary aim of this article is to review literature regarding the relationship between substance use and HIV transmission in Peru. Methods Detailed search of published literature completed in PubMed and Google-Scholar and other local Peruvian publications. Mesh words: “Peru”; “substance-related-disorders”; “HIV”; “sexual-behavior” and their combinations. From 3921 articles, 150 were chosen for more careful review and only 26 were used for the review. No date limit was used in this review. Results Peruvian HIV epidemic is limited to MSM and its prevalence goes up to 33% in certain MSM-subpopulations. Transmission is mainly through sexual contact. Drug use doubled the risk for casual sex, decreased by half the chances of using condoms, increased the number of partners per year and the risk for STD’s. Peruvian HIV-positive populations have higher rates drug use and using drugs have been associated with a higher prevalence of being HIV-positive. This may be also true for other populations such as pregnant women in which there is an association between drug use and HIV. Conclusions Although the amount of Peruvian research in this area limits the review, there seems to be a relationship between using drugs, having risky-sexual-behaviors and being HIV positive in Peru. HIV-prevention strategies for Peruvians must address the link between sex and substance use. PMID:25264494

    Malaria in Peru, dominated by Plasmodium vivax, remains a public health problem. The 1990s saw newly epidemic malaria emerge, primarily in the Loreto Department in the Amazon region, including areas near to Iquitos, the capital city, but sporadic malaria transmission also occurred in the 1990s-2000s in both north-coastal Peru and the gold mining regions of southeastern Peru. Although a Global Fund-supported intervention (PAMAFRO, 2005-2010) was temporally associated with a decrease of malaria transmission, from 2012 to the present, both P. vivax and Plasmodium falciparum malaria cases have rapidly increased. The Peruvian Ministry of Health continues to provide artemesinin-based combination therapy for microscopy-confirmed cases of P. falciparum and chloroquine-primaquine for P. vivax Malaria transmission continues in remote areas nonetheless, where the mobility of humans and parasites facilitates continued reintroduction outside of ongoing surveillance activities, which is critical to address for future malaria control and elimination efforts. Ongoing P. vivax research gaps in Peru include the following: identification of asymptomatic parasitemics, quantification of the contribution of patent and subpatent parasitemics to mosquito transmission, diagnosis of nonparasitemic hypnozoite carriers, and implementation of surveillance for potential emergence of chloroquine- and 8-aminoquinoline-resistant P. vivax Clinical trials of tafenoquine in Peru have been promising, and glucose-6-phosphate dehydrogenase deficiency in the region has not been observed to be a limitation to its use. Larger-scale challenges for P. vivax (and malaria in general) in Peru include logistical difficulties in accessing remote riverine populations, consequences of government policy and poverty trends, and obtaining international funding for malaria control and elimination.

  20. From anti-natalist to ultra-conservative: restricting reproductive choice in Peru.

    2004-11-01

    This article examines Peru's population policy since the 1994 International Conference on Population and Development and assesses to what extent its policies and programmes have affected reproductive health and rights. It is drawn from data collected during ongoing monitoring of sexual and reproductive health policies and programmes in Peru since 1998 for the Center for Health and Gender Equity (CHANGE). Accomplishments since 1994 in Peru demonstrate good faith on the port of the government and foreign donors to make progress towards fulfilling the ICPD agenda by addressing key reproductive health concerns and promoting women's rights. Unfortunately, this progress has not been consistent. It has been overshadowed by two periods of anti-choice policies and interventions. The first, in 1996--97 under the Fujimori government, was a demographic approach that used numerical targets and undue pressure on women to accept sterilisation as the government's main poverty reduction strategy, which led to documented abuses. The second, in 2001--03 under the Toledo government, was a far-right approach that worked to limit access to essential services, including emergency contraception, condoms and post-abortion core. In spite of their contradictory nature, these two policy approaches have been the greatest obstacles to making long-lasting improvements to reproductive health and rights in Peru.

    Nutrients play a fundamental role as regulators of the activity of enzymes involved in liver metabolism. In the general population, the action of nutrients may be affected by gene polymorphisms. Therefore, individualization of a diet for individuals with fatty liver seems to be a fundamental step in nutritional strategies. In this study, we tested the nutrient-induced insulin output ratio (NIOR), which is used to identify the correlation between the variants of genes and insulin resistance. We enrolled 171 patients, Caucasian men (n = 104) and women (n = 67), diagnosed with non-alcoholic fatty liver disease (NAFLD). From the pool of genes sensitive to nutrient content, we selected genes characterized by a strong response to the NIOR. The polymorphisms included Adrenergic receptor (b3AR), Tumor necrosis factor (TNFα), Apolipoprotein C (Apo C III). Uncoupling Protein type I (UCP-1), Peroxisome proliferator activated receptor γ2 (PPAR-2) and Apolipoprotein E (APOEs). We performed three dietary interventions: a diet consistent with the results of genotyping (NIOR (+)); typical dietary recommendations for NAFLD (Cust (+)), and a diet opposite to the genotyping results (NIOR (−) and Cust (−)). We administered the diet for six months. The most beneficial changes were observed among fat-sensitive patients who were treated with the NIOR (+) diet. These changes included improvements in body mass and insulin sensitivity and normalization of blood lipids. In people sensitive to fat, the NIOR seems to be a useful tool for determining specific strategies for the treatment of NAFLD. PMID:27455252

    The goal of the International Journal of Behavioral Nutrition and Physical Activity (IJBNPA) is to be the leading diet and physical activity journal. To achieve this aim we embrace and publish a number of different research designs from small, but in depth, qualitative studies to large scale cohort studies. IJBNPA prioritises research based on randomised controlled trials (RCTs), systematic reviews (with or without meta-analyses, as appropriate), and well conducted observational studies that expand knowledge and understanding of the area. IJBNPA will also consider and publish other study designs that are of sufficient quality such as strong or ground-breaking methodological papers, rigorous qualitative studies, debate papers and commentaries. However, due to the demands on the journal, we publish pilot studies only in exceptional circumstances and we do not publish protocol papers or letters to the editors. The goal of this editorial is to highlight to our readers and authors the process by which we identify which papers to review and publish along with our editorial priorities.

    Plant-based foods offer a wide range of nutrients that are essential for human and animal health. Among these nutrients, iron stands out as one of the most important micronutrients. Increasing the iron content in many staple and non-staple plant foods continues to be a goal of many scientists around the world. However, the success of such initiatives has sometimes fallen short of their expected targets. In this review we highlight the most recent and promising results that have contributed to increasing the iron content in different crops. We also discuss methods that to date have been used to reach iron biofortification goals and new strategies that we believe are most promising for crop biofortification in the future. Plant anatomical, physiological and metabolic hurdles still need to be tackled for making progress on further increasing currently reached levels of micronutrient improvements. New strategies need to take into account growing environmental challenges that may constrain biofortification efforts.

    Undernutrition and obesity have serious implications for both health and recovery from illness or surgery. These nutritional problems are common in hospital patients but often go unnoticed. This article reviews the means of carrying out nutritional assessment and recommends simple techniques for routine use at ward level to identify patients who need nutritional intervention. Nursing staff are in an ideal position to undertake nutritional screening and simple nutritional assessment should be routinely included as part of patient assessment.

    Obesity and nonalcoholic steatohepatitis are increasing in westernized countries, regardless of their geographic location. In Latin America, most countries, including Mexico, have a heterogeneous admixture genome with Amerindian, European and African ancestries. However, certain high allelic frequencies of several nutrient-related polymorphisms may have been achieved by past gene-nutrient interactions. Such interactions may have promoted the positive selection of variants adapted to regional food sources. At present, the unbalanced diet composition of the Mexicans has led the country to a 70% prevalence rate of overweightness and obesity due to substantial changes in food habits, among other factors. International guidelines and intervention strategies may not be adequate for all populations worldwide because they do not consider disparities in genetic and environmental factors, and thus there is a need for differential prevention and management strategies. Here, we provide the rationale for an intervention strategy for the prevention and management of obesity-related diseases such as non-alcoholic steatohepatitis based on a regionalized genome-based diet. The components required to design such a diet should focus on the specific ancestry of each population around the world and the convenience of consuming traditional ethnic food. PMID:25834309

    Background Cystic echinococcosis (CE) constitutes an important public health problem in Peru. However, no studies have attempted to estimate the monetary and non-monetary impact of CE in Peruvian society. Methods We used official and published sources of epidemiological and economic information to estimate direct and indirect costs associated with livestock production losses and human disease in addition to surgical CE-associated disability adjusted life years (DALYs) lost. Findings The total estimated cost of human CE in Peru was U.S.$2,420,348 (95% CI:1,118,384–4,812,722) per year. Total estimated livestock-associated costs due to CE ranged from U.S.$196,681 (95% CI:141,641–251,629) if only direct losses (i.e., cattle and sheep liver destruction) were taken into consideration to U.S.$3,846,754 (95% CI:2,676,181–4,911,383) if additional production losses (liver condemnation, decreased carcass weight, wool losses, decreased milk production) were accounted for. An estimated 1,139 (95% CI: 861–1,489) DALYs were also lost due to surgical cases of CE. Conclusions This preliminary and conservative assessment of the socio-economic impact of CE on Peru, which is based largely on official sources of information, very likely underestimates the true extent of the problem. Nevertheless, these estimates illustrate the negative economic impact of CE in Peru. PMID:21629731

  11. Peru's population in the 1980s.

    Sanders, T G

    1984-12-01

    In this discussion of Peru's population in the 1980s, attention focuses on the following; population growth; population policy and family planning; internal migration; and economic and social characteristics. Peru's rate of population growth was 1.8% annually between the censuses of 1940-61, a little less than 2.9% between 1961-71, and 2.7% in the decade preceding the 1981 census. These figures demonstrate that the national population is now growing at a less rapid rate than 1 or 2 decades ago but that Peru did not experience a marked drop like that in several other countries. As with overall population growth, the decline of fertility in Peru has been slow and gradual. During the past 20 years the crude birthrate dropped from 46.27 to 36.71/1000 and the total fertility rate from 6.85 to 5.00. The reason why Peru's population growth rate never exceeded 3% is a direct result of its exceptionally high mortality and infant mortality levels. Peru has a crude mortality rate of 10.74/1000 and an infant mortality rate of 98.63/1000. These are extremely high compared with other Latin American countries. Theoretically, the momentum of progress should be carrying Peru rapidly into the demographic transition. Some modernizing factors, i.e., improved health care, urbanization, communications, and education, are slowly reducing fertility and mortality, but progress on other factors such as per capita income and social mobility is not occurring. A table projects Per's population at various projected growth rates until 2025. Differences in fertility among Peruvian women indicate that family planning and contraception are relatively common in urban areas. The adoption of contraception occurred totally without government assistance before 1980, when policy changed. Until then, Peru was the only major Latin American country with population growing at over 2.5% annually that did not have some kind of public family planning program. In 1981 a survey on contraceptive use was conducted

    The impact of the internal armed conflict in Peru (1980-2000) was felt in many regions in this South American country, and especially in rural regions such as the Southern Andean province of Cotabambas in the Apurímac department. This article describes and analyzes the actions and results of a community mental health project in this area that aimed to address the conflict's aftermath. The intervention used participatory strategies to identify the communities' prioritized problems, established actions appropriate to the cultural characteristics of the population, and implemented creative and recreational initiatives that responded to communities' needs. Based on democratic dialogue, horizontal relations, and reciprocity, the targeted communities became protagonists in the process of psychosocial transformation that fostered individual and collective exercise of rights, individual human development, and democratic community building.

    2013-12-01

    The incidence of malnutrition in hospitalized patients is relatively high (up to 55%) despite breakthroughs in nutrition support therapies. These patients have increased morbidity and mortality, extended hospital stays, and care that is associated with higher costs. These patients are often poorly managed due to inadequate nutrition assessment and poor medical knowledge and practice in the field of nutrition. Nutrition support teams (NSTs) are interdisciplinary support teams with specialty training in nutrition that are often comprised of physicians, dietitians, nurses, and pharmacists. Their role includes nutrition assessment, determination of nutrition needs, recommendations for appropriate nutrition therapy, and management of nutrition support therapy. Studies have demonstrated significant improvements in patient nutrition status and improved clinical outcomes as well as reductions in costs when patients were appropriately managed by a multispecialty NST vs individual caregivers. Despite this, there has been steady decline in the number of formal NST in recent years (65% of hospitals in 1995 to 42% in 2008) as hospitals and other healthcare organizations look for ways to cut costs. Given the importance of nutrition status on clinical outcomes and overall healthcare costs, a number of institutions have introduced and sustained strong nutrition training and support programs and teams, demonstrating both clinical and economic benefit. The benefits of NST, training and implementation strategies, and tips for justifying these clinically and economically beneficial groups to healthcare organizations and governing bodies are discussed in this review.

  14. Nutritional considerations in rheumatoid arthritis.

    PubMed

    Touger-Decker, R

    1988-03-01

    Rheumatoid arthritis is a chronic, systemic, inflammatory disorder of unknown etiology. The severity of the disease process adversely affects nutritional status. Articular changes, such as small joint deformities and temporomandibular joint syndrome, alter the ability to self-feed. The inflammatory process may increase metabolic rate. Ingestion, digestion, absorption, and excretion may be compromised by secondary manifestations of the disease. Comprehensive nutrition assessment incorporates evaluation of disease and treatment-specific factors, along with the usual assessment parameters. Abnormal values for certain assessment parameters do not necessarily reflect nutritional status. Treatment methods, including medications, may have an impact on nutritional status, assessment tools, and self-feeding. Nutrition management goals focus on identification and implementation of feeding strategies. Evaluation of the ability to feed oneself includes consideration of functional status, secondary manifestations, and medical treatment. Multiple feeding modalities may be required. Oral supplements, tube feedings, and parenteral nutrition may be employed to meet the nutrition needs of the individual with rheumatoid arthritis.

    Abstract Three new species of “non-spiny" Solanum are described from Peru and Ecuador, and a revised description for Solanum verecundum M. Nee is presented. Solanum kulliwaita S. Knapp, sp. nov. (Dulcamaroid clade) is endemic to the Department of Cuzco in southern Peru, and is most similar to the recently described Solanum sanchez-vegae S. Knapp of northern Peru. Solanum dillonii S. Knapp, sp. nov. (Brevantherum clade) is found in southern Ecuador and northern Peru in the Amotape-Huancabamba phytogeographic zone, and is morphologically similar to the widespread Solanum riparium Ruiz & Pav. Solanum oxapampense S. Knapp, sp. nov., (also of the Brevantherum clade) is endemic to the Oxapampa region (Department of Pasco) of central Peru, and is similar to and segregated from Solanum verecundum M. Nee of Peru and Ecuador. Complete descriptions, distributions and preliminary conservation assessments of all new species are given. PMID:22171167

    Carrion's disease, the iconic disease in Peruvian medicine has been found in the mountains of Ecuador, Colombia and the Andean valleys of Peru. In the 1990s, the phenomenon of El Niño was associated with significantly increased risk of disease in Ancash, Cajamarca and Cusco. In Cusco in 1998 there was an acute phase epidemic in various Andean provinces and the jungle area. Between 2001 and 2005 the disease has spread or reactivated in different regions such as Ancash, Cajamarca, Amazonas, Piura, Cusco, La Libertad, Puno, and Ayacucho. In 2004 a major outbreak of the disease in all of Peru was presented, reporting more than 11 164 cases, and therefore diverse strategies based vector susceptibility studies was applied, lowering significantly the number of cases.

    We report the results of a statistical study on the number of women entering the undergraduate and master's programs of physics at Universidad Nacional Mayor de San Marcos in Peru. From 2006 through 2010, 13 female students entered the master's degree program but no females graduated with the degree. Considering that Peru is a developing country, a career in physics is not considered an attractive professional choice even for male students because it is thought that there are no work centers to practice this profession. We recommend that the causes preventing female physics students from completing their studies and research work be analyzed, and that strategies be planned to help women complete their academic work. We are considering getting help from the Peruvian Physics Society (SOPERFI) in order to draw more attention for our plan.

    Health information systems play a key role in enabling high quality, complete health information to be available in a timely fashion for operational and strategic decision-making that makes it possible to save lives and improve the health and quality of life of the population. In many countries, health information systems are weak, incomplete, and fragmented. However, there is broad consensus in the literature of the need to strengthen health information systems in countries around the world. The objective of this paper is to present the essential components of the conceptual framework to strengthen health information systems in Peru. It describes the principal actions and strategies of the Ministry of Health of Peru during the process of strengthening health information systems. These systems make it possible to orient policies for appropriate decision-making in public health.

    Peru receives a high degree of solar radiation, except for part of its coastal area, and has almost an ideal climate for the development of solar energy. However, only recently has a concerted effort been made in Peru to take advantage of these conditions. Work focuses on the development of low-temperature applications, including the design of passive solar-heated buildings for the high Andes, the design and evaluation of various types of solar water heaters and crop dryers for both household and industrial uses (based on flat-plate collectors), and the construction of a desalinization prototype plant. Photovoltaic systems are being investigated for suitable applications and have an excellent potential, especially in telecommunications.

    Background Syndromic management is an inexpensive and effective method for the treatment of symptomatic sexually transmitted infections (STIs), but its effectiveness as a method of STI control in at-risk populations is questionable. We sought to determine the potential utility of syndromic management as a public health strategy to control STI transmission in high-risk populations in urban Peru. Methodology We surveyed 3,285 at-risk men and women from three Peruvian cities from 2003–05. Participants were asked about the presence of genital ulcers, discharge, or dysuria in the preceding six months. Participants reporting symptoms were asked about subsequent health-seeking and partner notification behavior. Urine and vaginal swab samples were tested for Neisseria gonorrhoeae and Chlamydia trachomatis by nucleic acid testing. Serum was tested for syphilis and Herpes Simplex Virus-Type 2 antibodies. Findings Recent urogenital discharge or dysuria was reported by 42.1% of participants with gonorrhea or chlamydia versus 28.3% of participants without infection. Genital ulceration was reported by 6.2% of participants with, and 7.4% of participants without, recent syphilis. Many participants reporting symptoms continued sexual activity while symptomatic, and approximately half of all symptomatic participants sought treatment. The positive and negative predictive values of urogenital discharge or genital ulcer disease in detecting STIs that are common in the study population were 14.4% and 81.5% for chlamydia in women and 8.3% and 89.5% for syphilis among gay-identified men. Conclusions In our study, STIs among high-risk men and women in urban Peru were frequently asymptomatic and symptomatic participants often remained sexually active without seeking treatment. Additional research is needed to assess the costs and benefits of targeted, laboratory-based STI screening as part of a comprehensive STI control program in developing countries. PMID:19779620

    Neurogenetics is an emerging discipline in Peru that links basic research with clinical practice. The Neurogenetics Research Center located in Lima, Peru is the only unit dedicated to the specialized care of neurogenetic diseases in the country. From the beginning, neurogenetics research has been closely linked to the study of Huntington’s Disease (HD), from the PCR genotyping of the HTT gene, to the current haplogroup studies in HD. Research in other monogenic diseases led to the implementation of alternative methodologies for the genotyping of Fragile X and Myotonic Dystrophy Type 1. Both, national and international collaborative efforts have facilitated the discovery of new genetic variants in complex multigenic diseases such as Parkinson’s disease and Alzheimer’s disease. Additionally, multidisciplinary education and mentoring have allowed for the training of new neurogenetics specialists, supporting the sustained growth of the discipline in the country. The promotion of research in Peru has spurred the growth of neurogenetics research, although limitations in infrastructure, technology, and education remain a challenge for the further growth of research in this field.

    PubMed

    Andrien, M; Beghin, I

    1993-12-01

    Seven years ago Hygie published an article on the limits of conventional nutrition education in urban Africa. Strategies and methods in communication for nutrition have since evolved, incorporating results of international research to develop innovative, highly participative approaches. In this article the authors provide an extensive analysis of the different methodologies used in nutrition education programmes, in particular the KAB, social marketing, and community participation models, indicating main areas where each method used separately has failed. Members of the African Nutritional Education Network (RENA) have studied the above mentioned approaches, modifying them or integrating certain elements to adopt a more effective approach, which they consider somewhat as the management of social communication for nutrition education. Needs assessments and programme planning are largely enhanced by a causal analysis component specific to nutrition education in a community setting which has been developed by the authors. Other classic elements of programme implementation such as community participation, diversity of methods and intervention, are then combined with a multi-level/multi-actor evaluation processes to produce what the authors esteem to be a more effective nutrition education programme. They conclude, however, with the warning that although behavioural modifications brought about by nutrition communication and education might be beneficial for public health, they could have different, possibly adverse effects on other aspects of society. Effective nutrition education must therefore be included in a more extensive field of health promotion by acting on the multiple factors which influence the nutrition and health state of vulnerable groups.

    Nutritional stunting is a common problem of the pediatric population especially in developing countries. Although it is a resolvable problem, it continues to be an important health issue. Stunting can be diagnosed when a child's height falls more than two standard deviations below the mean height for age. Stunting may be caused by genetic, hormonal, pharmaceutical, psychosocial and nutritional factors. Before doing extensive laboratory tests, nutritional factors must be searched for at the time of diagnosis. If the etiology is nutritional deficiency, meticulous dietary regulation must be done. The results of treatment must be assessed for guiding the nutritional rehabilitation during follow up. Here we review the interaction of wasting and nutritional stunting; the prevalence of nutritional stunting; diet components and growth; the pathophysiology of stunting; periods of accelerated growth; the diagnosis and clinical assessment of nutritional stunting; the anthropometric and laboratory nutritional indices that can be used at the time of diagnosis and for follow-up purposes during rehabilitation and also the management of nutritional stunting.

    Background Several risk factors for noncommunicable diseases (NCDs), including obesity, are associated with behaviors established in infancy that persist throughout adolescence and adulthood. As such, adolescents should be engaged in the design and implementation of NCD prevention strategies. Community Context In Lima, Peru’s capital, the proportion of adolescents aged 15 to 19 is 9.3% of the city’s population, and school enrollment rates are high. The prevalence of excess weight in Peruvian adolescents is 14.2%, and prevalence has not declined in recent years. Also recently, NCDs and their risk factors have gained more attention in public health and policy areas, with regulatory action focusing on healthful nutrition to address obesity and related NCDs. The Multiplicadores Jóvenes (Young Multipliers) project was conducted among adolescents aged 15 to 17 from 9 public secondary schools in peri-urban areas of Lima, Peru. Methods The project provided basic communication tools and knowledge of NCD prevention and public health research to adolescents during 16 weekly participatory sessions to enable them to design and disseminate healthful lifestyle promotion messages to their school peers. Outcome Thirty of 45 participants finished the program. Seven communications campaigns were designed and implemented in schools, reaching 1,200 students. The participants gained motivation, increased knowledge, and developed communication skills that were combined to implement healthful lifestyle promotion campaigns. Interpretation Engaging young people in public health promotion activities was feasible and advantageous for the design of tailored prevention-related content and its dissemination among peers.

    Objectives In Peru, a country with constrained health resources, breast cancer control is characterized by late stage treatment and poor survival. To support breast cancer control in Peru, this study aims to determine the cost-effectiveness of different breast cancer control interventions relevant for the Peruvian context. Methods We performed a cost-effectiveness analysis (CEA) according to WHO-CHOICE guidelines, from a healthcare perspective. Different screening, early detection, palliative, and treatment interventions were evaluated using mathematical modeling. Effectiveness estimates were based on observational studies, modeling, and on information from Instituto Nacional de Enfermedades Neoplásicas (INEN). Resource utilizations and unit costs were based on estimates from INEN and observational studies. Cost-effectiveness estimates are in 2012 United States dollars (US$) per disability adjusted life year (DALY) averted. Results The current breast cancer program in Peru ($8,426 per DALY averted) could be improved through implementing triennial or biennial screening strategies. These strategies seem the most cost-effective in Peru, particularly when mobile mammography is applied (from $4,125 per DALY averted), or when both CBE screening and mammography screening are combined (from $4,239 per DALY averted). Triennially, these interventions costs between $63 million and $72 million per year. Late stage treatment, trastuzumab therapy and annual screening strategies are the least cost-effective. Conclusions Our analysis suggests that breast cancer control in Peru should be oriented towards early detection through combining fixed and mobile mammography screening (age 45-69) triennially. However, a phased introduction of triennial CBE screening (age 40-69) with upfront FNA in non-urban settings, and both CBE (age 40-49) and fixed mammography screening (age 50-69) in urban settings, seems a more feasible option and is also cost-effective.

    Abstract Iron deficiency causes anaemia and other adverse effects on the nutritional status and development of millions of children. Multi‐micronutrient powders (MNP) have been shown to reduce anaemia in young children. In Peru, 50% of children 6–36 months are anaemic. Since 2009, the government has started distributing MNP. This qualitative study explored the acceptability of MNP by caregivers and the role of health personnel (HP) in three regions (Apurimac, Ayacucho and Cajamarca), piloting the MNP programme between 2009 and 2011. Data collection consisted of interviews (35) and observations (13) with caregivers and HP (11). In Cajamarca, 16 families were visited three times in their homes to understand caregivers' use and difficulties. Results showed the critical role HP has in influencing caregiver understanding and use of the MNP, as well as the need for training to avoid confusing messages and provide counselling techniques that consider cultural sensitivity to optimize HP interactions with caregivers and adapt the recommendations for MNP use to local family feeding routines. There was greater acceptance of MNP by caregivers giving semi‐solid foods (e.g. purees) to their children than those who served dilute preparations (e.g. soups). Acceptance was similar across regions, but there were some differences between urban and rural settings. Home visits were shown to be a key in improving the use of MNP by caregivers as misunderstandings on preparation, required consistency and optimum practices were common. These findings can contribute to strategies to enhance acceptability and use. Key messages Acceptance and use of multi‐micronutrient powders (MNP) by caregivers greatly depend upon how it is presented, promoted and counselled by health personnel.Counselling for MNP use needs to consider and adapt to the local cultural context and incorporate family and child feeding routines.MNP are presented as part of appropriate feeding practices, encouraging

    Background Currently, there is a paucity of data regarding human adenovirus (HAdv) circulation in Andean regions of South America. To address this shortcoming, we report the clinical, phylogenetic, and epidemiologic characteristics of HAdv respiratory tract infection from a large sentinel surveillance study conducted among adults and children in Peru. Methods/Principal Findings Oropharyngeal swabs were collected from participants visiting any of 38 participating health centers, and viral pathogens were identified by immunofluorescence assay in cell culture. In addition, molecular characterization was performed on 226 randomly selected HAdv samples. Between 2000 and 2010, a total of 26,375 participants with influenza-like illness (ILI) or severe acute respiratory infection (SARI) were enrolled in the study. HAdv infection was identified in 2.5% of cases and represented 6.2% of all viral pathogens. Co-infection with a heterologous virus was found in 15.5% of HAdv cases. HAdv infection was largely confined to children under the age of 15, representing 88.6% of HAdv cases identified. No clinical characteristics were found to significantly distinguish HAdv infection from other respiratory viruses. Geographically, HAdv infections were more common in sites from the arid coastal regions than in the jungle or highland regions. Co-circulation of subgroups B and C was observed each year between 2006 and 2010, but no clear seasonal patterns of transmission were detected. Conclusions/Significance HAdv accounted for a significant fraction of those presenting with ILI and SARI in Peru and tended to affect the younger population disproportionately. Longitudinal studies will help better characterize the clinical course of patients with HAdv in Peru, as well as determine the role of co-infections in the evolution of illness. PMID:23056519

  8. Maternal nutritional knowledge and the nutritional status of preschool children in a Nairobi slum.

    Most nutrition education programmes in Kenya operate on the premise that nutritional knowledge can have an impact on children's nutritional status. It has, however, been argued that nutritional knowledge among low income groups is unlikely to have an impact, hence, the need to establish whether there is a relationship between nutritional status and maternal nutritional knowledge. In a cross-sectional survey carried out in a Nairobi slum (Kibera), nutritional status of 363 children aged six to 24 months was measured and nutritional knowledge of their mothers assessed. Makina village was randomly selected as the study site and all consenting households were involved in the study. The study established that most mothers (97.5%) have access to nutrition education. Prevalence of stunting (86.2%) and underweight (58.4%) was high but that of wasting (1.9%) was low. There was no significant relationship between the nutritional status of children and overall nutritional knowledge. Unexpectedly, a negative relationship was found between nutritional status and mothers' ability to recognise clinical signs of malnutrition, knowledge in the weaning process and dietary management during sickness. Knowledge on frequency of feeding was, however, positively related to nutritional states. In conclusion, nutritional knowledge alone is inadequate in ensuring young children's nutrition security and, hence, for nutrition education programmes to have a positive impact, facilitational strategies must be incorporated.

    We present the case of a full-term female newborn, whose mother died seven days postpartum from multi-organ failure due to severe dengue confirmed by NS1 antigen detection and positive IgM. The newborn did not have any complication, but at the fourth day of life she developed fever, jaundice, signs of plasma leakage, thrombocytopenia, hepatomegaly, ascitis, and others signs of systemic inflammation response syndrome. She fully recovered with supportive treatment. The RT-PCR test of a peripheral blood sample revealed a positive result for the dengue virus serotype 2, confirming the first case of neonatal dengue reported in Peru.

    For most crops, like Capsicum, their diversity remains under-researched for traits of interest for food, nutrition and other purposes. A small investment in screening this diversity for a wide range of traits is likely to reveal many traditional varieties with distinguished values. One objective of this study was to demonstrate, with Capsicum as model crop, the application of indicators of phenotypic and geographic diversity as effective criteria for selecting promising genebank accessions for multiple uses from crop centers of diversity. A second objective was to evaluate the expression of biochemical and agromorphological properties of the selected Capsicum accessions in different conditions. Four steps were involved: 1) Develop the necessary diversity by expanding genebank collections in Bolivia and Peru; 2) Establish representative subsets of ~100 accessions for biochemical screening of Capsicum fruits; 3) Select promising accessions for different uses after screening; and 4) Examine how these promising accessions express biochemical and agromorphological properties when grown in different environmental conditions. The Peruvian Capsicum collection now contains 712 accessions encompassing all five domesticated species (C. annuum, C. chinense, C. frutescens, C. baccatum, and C. pubescens). The collection in Bolivia now contains 487 accessions, representing all five domesticates plus four wild taxa (C. baccatum var. baccatum, C. caballeroi, C. cardenasii, and C. eximium). Following the biochemical screening, 44 Bolivian and 39 Peruvian accessions were selected as promising, representing wide variation in levels of antioxidant capacity, capsaicinoids, fat, flavonoids, polyphenols, quercetins, tocopherols, and color.

    Six species of oribatid mites of the genus Pergalumna (Oribatida, Galumnidae) are collected from the German Expedition to Amazonian Peru in 2013; of these, three are new for science, described from upper soil and leaf litter in the primary evergreen lowland rainforest. Pergalumna (Pergalumna) parapassimpunctata sp. nov. is morphologically most similar to P. (P.) passimpunctata Balogh & Mahunka, 1969, but differs from the latter by the presence of foveolate body surface, two pairs of porose areas Aa and minute interlamellar setae, and the absence of porose areas A3. Pergalumna (Pergalumna) krisperi sp. nov. is morphologically most similar to P. (P.) cardosensis Pérez-Íñigo & Baggio, 1986, but differs from the latter by the smaller body size, rostral and lamellar setae of medium size and the presence of four pairs of notogastral porose areas. Pergalumna (Pergalumna) lenticulata sp. nov. is morphologically most similar to P. (P.) decorata Balogh & Mahunka, 1977, but differs from the latter by the larger body size and the presence of lenticulus and bidentate rostrum. The species Pergalumna (Pergalumna) bryani Jacot, 1934 is recorded for the first time in Peru.

  18. Astrology in seventeenth-century Peru.

    PubMed

    Brosseder, Claudia

    2010-06-01

    This article discusses three aspects of the history of astrology in seventeenth-century Peru that are of larger interest for the history of science in Latin America: Creole concerns about indigenous idolatry, the impact of the Inquisition on natural philosophy, and communication between scholars within the Spanish colonies and the transatlantic world. Drawing mainly on the scholars Antonio de la Calancha, Juan de Figueroa, and Ruiz de Lozano, along with several Jesuits, the article analyzes how natural and medical astrology took shape in Peru and how they fostered astronomical investigations of the southern skies. While natural and medical astrology, showing New and Old World influences, oscillated between orthodoxy and heterodoxy, and between scholasticism and new science, judicial astrology remained undeveloped. Toward the end of the seventeenth century the discourse about astrology took an unexpected turn, reflecting a newly invigorated moral and Christian reading of the heavens that was in part a response to a deep-rooted dissatisfaction with the failure of the extirpation of idolatry campaigns. Inscribing divine and cardinal virtues, the Virgin Mary, Christian saints, and Greco-Roman allegories into the heavens was considered a way to finally solve the problem of idolatry and to convey Creole greatness.

    Although encephalomyocarditis virus (EMCV) infection has been commonly documented among domestic animals, less is known about EMCV transmission among humans. Recently, we described the isolation of EMCV from two febrile patients in Peru. To further investigate EMCV transmission in Peru, we screened febrile patients reporting to health clinics in Peru for serological evidence of recent EMCV infection. We also conducted a serological survey for EMCV-neutralizing antibodies in the city of Iquitos, located in the Amazon basin department of Loreto, Peru. Additionally, we screened serum from rodents collected from 10 departments in Peru for evidence of EMCV exposure. EMCV infection was found to be only rarely associated with acute febrile disease in Peru, accounting for <1% of febrile episodes analyzed. Despite the low acute disease burden associated with the virus, human exposure was quite common, as prevalence of EMCV-neutralizing antibodies ranged between 6.0% in the coastal city of Tumbes and >17% in cities in the tropical rainforest of northeastern Peru (Iquitos and Yurimaguas). On the basis of the serological survey conducted in Iquitos, risk factors for past infection include increased age, socioeconomic indicators such as residence construction materials and neighborhood, and swine ownership. Evidence from the rodent survey indicates that EMCV exposure is common among Murinae subfamily rodents in Peru (9.4% EMCV IgG positive), but less common among Sigmodontinae rodents (1.0% positive). Further studies are necessary to more precisely delineate the mode of EMCV transmission to humans, other potential disease manifestations, and the economic impact of EMCV transmission among swine in Peru.

    A health problem each time more frequent and dispersed in tropical and subtropical areas of the world, including Peru where it entered in 1990, is dengue. It is produced by the dengue virus with four serotypes and transmitted by Aedes aegypti, a vector that coexists with humans and whose presence is favored by deficient sanitary, social and economic conditions. Manifestations of severe forms of the disease such as shock and bleeding, are related to the frequent co-circulation of the four serotypes and the emergence of new genotypes such as American/Asian serotype 2. The new classification of the disease by WHO as dengue with or without warning signs and severe dengue, is contributing to more timely diagnosis and treatment, enabling reductions in mortality. Of note is the need to highlight the surveillance of acute febrile illness and Aedes indices that contribute to a timely diagnosis and guide vector control measures through sanitary education and environmental management with community and intersectoral participation, in a creative manner according to ecological niches. An alternative for complementary prevention would be vaccination using tetravalent vaccines whose safety and efficacy must be guaranteed before its use in the population under the framework of comprehensive strategies.

    The extensive literature on nutrition in pregnancy is reviewed with special reference to international experience, including observations on nutritional trials in pregnancy, pregnancy during famines caused by war, and studies of birth-weight in relation to pregnancy interval, parity and multiple pregnancies. Recent research on the significance of fetal nutrition suggests that ”small-for-dates” infants, i.e., those that are developmentally retarded in utero, suffer long-term developmental sequelae. A high world-wide incidence of small-for-dates births was reported by the World Health Organization in 1960. Although a definite correlation has been found between socio-economic status and birth-weight, it is not known to what extent the smaller birth-weights observed in the lower socio-economic groups can be improved by specific nutritional measures. In addition to the general advice given on maternal nutrition and family-planning, further studies are needed to determine the precise means of achieving improvement in fetal nutrition and a better outcome of pregnancy.

    Optimal nutrition will be critical for crew members who embark on space exploration missions. Nutritional assessment provides an opportunity to ensure that crewmembers begin their missions in optimal nutritional status, to document changes during a mission and, if necessary, to provide intervention to maintain that status throughout the mission, and to assesses changes after landing in order to facilitate the return to their normal status as soon as possible after landing. We report here the findings from our nutritional assessment of astronauts who participated in the International Space Station (ISS) missions, along with flight and ground-based research findings. We also present ongoing and planned nutrition research activities. These studies provide evidence that bone loss, compromised vitamin status, and oxidative damage are the critical nutritional concerns for space travelers. Other nutrient issues exist, including concerns about the stability of nutrients in the food system, which are exposed to longterm storage and radiation during flight. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health.

Chan Chan was the capital of the Chimú Empire (A.D. 1100-1400) and the largest pre-Columbian city in the Americas. These furnaces, my guide explained, were where Andean gold, silver and copper ores were smelted and fabricated into jewelry, masks and plates sought by the Spaniards.

    American Trypanosomosis is an important parasitic infection in Peru. Human cases, reservoirs and vectors have been showed in two known geographic areas in the endemic zones: southwestern and northern and northeastern regions of the country; however vectors belonging to the three genera of triatominae: Triatoma, Panstrongylus and Rhodnius have been collected in almost all the territory. The serological surveys in blood banks in the southwestern region is 2-6% and human cases found out of the endemic areas show the possibility of congenital cases. The study of the prevalence is starting. This preliminary study performed on 3000 pregnant of Arequipa shows serological positives in 22 (0.7%) and only a newborn positive at IgM. This result indicates a probable low rate of congenital transmission and necessary to perform more studies.

    Malnutrition is often seen at the point of diagnosis in childhood malignancy or may develop during the course of treatment. Strategies for optimal diagnosis and management of nutritional problems in children with cancer are limited in the published literature. Identification of children who may be malnourished or at nutritional risk can be achieved through improved approaches for risk stratification and classification. Once recognised, various strategies have been demonstrated to reduce malnutrition, minimise side effects of treatment and improve survival. Novel approaches in vivo and adult oncology populations provide future avenues for investigation.

    Calcium is an essential macronutrient for plants and animals and plays an indispensable role in structure and signaling. Low dietary intake of calcium in humans has been epidemiologically linked to various diseases which can have serious health consequences over time. Major staple food-grains are poor source of calcium, however, finger millet [Eleusine coracana (L.) Gaertn.], an orphan crop has an immense potential as a nutritional security crop due to its exceptionally high calcium content. Understanding the existing genetic variation as well as molecular mechanisms underlying the uptake, transport, accumulation of calcium ions (Ca(2+)) in grains is of utmost importance for development of calcium bio-fortified crops. In this review, we have discussed molecular mechanisms involved in calcium accumulation and transport thoroughly, emphasized the role of molecular breeding, functional genomics and transgenic approaches to understand the intricate mechanism of calcium nutrition in finger millet. The objective is to provide a comprehensive up to date account of molecular mechanisms regulating calcium nutrition and highlight the significance of bio-fortification through identification of potential candidate genes and regulatory elements from finger millet to alleviate calcium malnutrition. Hence, finger millet could be used as a model system for explaining the mechanism of elevated calcium (Ca(2+)) accumulation in its grains and could pave way for development of nutraceuticals or designer crops.

    Adequate nutritional status is critical for maintenance of crew health during extended- duration space flight and postflight rehabilitation. Nutrition issues relate to intake of required nutrients, physiological adaptation to weightlessness, psychological adaptation to extreme environments, and countermeasures to ameliorate the negative effects of space flight. Thus, defining the nutrient requirements for space flight and ensuring provision and intake of those nutrients are critical issues for crew health and mission success. Specialized nutritional requirements have only been considered for what are referred to here as extended- duration flights, i.e., those greater than 30 days in length. While adequate nutrition is important on the 1- to 3-week Shuttle flights, intakes of specific nutrients above or below space specific requirements for this period will not produce cause for concern. Thus, Shuttle flights have always used the recognized nutritional requirements for adult men and women. In this chapter, long-duration flights will be further differentiated into orbital missions (e.g., International Space Station) and interplanetary exploration missions.

    Special Operations Forces (SOF) training, combat, and contingency operations are unique and demanding. Performance nutrition within the Department of Defense has emphasized that nutrition is relative to factors related to the desired outcome, which includes successful performance of mentally and physically demanding operations and missions of tactical and strategic importance, as well as nonoperational assignments. Discussed are operational, nonoperational, and patient categories that require different nutrition strategies to facilitate category-specific performance outcomes. Also presented are 10 major guidelines for a SOF comprehensive performance nutrition program, practical nutrition recommendations for Special Operators and medical providers, as well as resources for dietary supplement evaluation. Foundational health concepts, medical treatment, and task-specific performance factors should be considered when developing and systematically implementing a comprehensive SOF performance nutrition program. When tailored to organizational requirements, SOF unit- and culture-specific nutrition education and services can optimize individual Special Operator performance, overall unit readiness, and ultimately, mission success.

    This article discusses the deficits in food security in India. It is recommended that India commit to nutrition security by direct actions. Programs should provide essential staples and a nutrient distribution system with affordable prices. India should adopt an Employment Guarantee Program. Creches should provide maternal-child health care, nutrition, literacy, and employment. Government must resolve the internal conflicts of interest between overlapping sectors. India should resolve the "dysfunction" between macroeconomic policies and anti-poverty strategies. Interventions should be people oriented, rely on social mobilization, and provide information and financial resources in a nonconflict context. Efforts will require the cooperation between the private sector, voluntary organizations, state agencies, and local self-governing decentralized agencies. There is a need to build capacity and viable institutions. Poverty agencies do not have access to the minimum required cereals for the poor. The Public Distribution System (PDS) does not guarantee a minimum quantity of foodstuffs per household regardless of income level. More high quality varieties of rice are produced due to higher prices in the marketplace. Most state governments do not provide staple cereals to the PDS at affordable prices. The government sets fair prices for sugar, but not cereal. The government sells more cereal in the open market than to PDS. PDS should target poor households; that is, the 29.9% who live below the poverty line. Lack of nutrition security is due to poverty that is enhanced by ignorance and the lack of health and nutrition education.

    The Peruvian Andes presents a climate suitable for many species of sandfly that are known vectors of leishmaniasis or bartonellosis, including Lutzomyia peruensis (Diptera: Psychodidae), among others. In the present study, occurrences data for Lu. peruensis were compiled from several items in the scientific literature from Peru published between 1927 and 2015. Based on these data, ecological niche models were constructed to predict spatial distributions using three algorithms [Support vector machine (SVM), the Genetic Algorithm for Rule-set Prediction (GARP) and Maximum Entropy (MaxEnt)]. In addition, the environmental requirements of Lu. peruensis and three niche characteristics were modelled in the context of future climate change scenarios: (a) potential changes in niche breadth; (b) shifts in the direction and magnitude of niche centroids, and (c) shifts in elevation range. The model identified areas that included environments suitable for Lu. peruensis in most regions of Peru (45.77%) and an average altitude of 3289 m a.s.l. Under climate change scenarios, a decrease in the distribution areas of Lu. peruensis was observed for all representative concentration pathways. However, the centroid of the species' ecological niche showed a northwest direction in all climate change scenarios. The information generated in this study may help health authorities responsible for the supervision of strategies to control leishmaniasis to coordinate, plan and implement appropriate strategies for each area of risk, taking into account the geographic distribution and potential dispersal of Lu. peruensis.

    Over recent years, modelling approaches from nutritional ecology (known as Nutritional Geometry) have been increasingly used to describe how animals and some other organisms select foods and eat them in appropriate amounts in order to maintain a balanced nutritional state maximising fitness. These nutritional strategies profoundly affect the physiology, behaviour and performance of individuals, which in turn impact their social interactions within groups and societies. Here, we present a conceptual framework to study the role of nutrition as a major ecological factor influencing the development and maintenance of social life. We first illustrate some of the mechanisms by which nutritional differences among individuals mediate social interactions in a broad range of species and ecological contexts. We then explain how studying individual- and collective-level nutrition in a common conceptual framework derived from Nutritional Geometry can bring new fundamental insights into the mechanisms and evolution of social interactions, using a combination of simulation models and manipulative experiments.

    2017-02-01

    Frailty and sarcopenia are important concepts in the quest to prevent physical dependence, as geriatrics are shifting towards identifications of early stages of disability. Definitions of both sarcopenia and frailty are still developing, and both concepts clearly overlap in their physical aspects. Malnutrition (both undernutrition and obesity) plays a key role in the pathogenesis of frailty and sarcopenia. The quality of the diet along the lifespan has a close relation with the incidence of both entities, and nutritional interventions may be able to reduce the incidence or revert either of them. This brief review explores the role of energy and protein intake and other key nutrients on muscle function. Nutrition may be a key element of multimodal interventions for frailty and sarcopenia. The results of the "Sarcopenia and Physical fRailty IN older people: multi-componenT Treatment strategies" (SPRINTT) trial will offer key insights on the effect of such interventions in frail, sarcopenic older individuals.

    2012-12-01

    Landslides originating from inner slopes of moraine dams are often capable of producing glacial lakes outburst floods (GLOFs). Therefore assessing stability conditions of the moraines is important for predicting this potentially damaging phenomenon. Characteristics of the basic mechanical properties of the material and geophysical investigations were applied to collect necessary information for slope stability assessment of the Palcacocha Lake moraine dam, Peru. The lake is situated in the Cordillera Blanca Mts. at the altitude of about 4,500m asl and produced catastrophic GLOF in 1941. Another minor flood originated in 2003 due to landslide impact into the lake. Detailed investigations of this landslide site included geomorphological mapping, geophysical investigations and characterization of basic mechanical properties of the forming material. Geomorphological mapping identified dormant landslide with scarp up to 2m high which developed on the edge of the inner moraine slope. It is conditioned by set of parallel extension trenches which also affected the origin of 2003 landslide. Within its scarp area, significant water bearing layer was noticed around 10 m bellow the moraine surface. Three profiles were investigated using electric resistivity tomography performed on 4poing light instrument with 24 electrodes and with spacing ranging from 1 to 4m. Results helped to verify geometry of the main shear plane of the mapped landslide as well as the spacing and depth of extension trenches. Significant heterogeneity in the moraine resistivity characteristics was found. The high resistivity regions are explained by rock block accumulation whereas the low resistivity may represent wet layers within the moraine body. Grain size distribution of 33 disturbed soil samples originating from moraine material within the Cordillera Blanca Mts., Peru were determined and classified according to the UCSC classification system. The samples were taken from moraine dams and slopes

  13. [Nutritional therapy of gout].

    PubMed

    Nickolai, Beate; Kiss, Caroline

    2016-01-01

    Nutrition and nutritional behaviours have been found to play a major role in the development of gout. Studies show that body mass index (BMI), as well as excessive intake of alcoholic beverages, meat, soft drinks and fruit juices increase the risk of developing gout. Similarly, dairy products and coffee have been seen to decrease the risk of hyperuricemia and gout, as they increase the excretion of uric acid. Flares of gout are often caused by large meals and high alcohol consumption. Each additional intake of meat portion per day increases the risk of gout by 21 %. Taking total alcohol consumption into account, the risk of gout increases after one to two standard drinks. In contrast to previous assumptions purine-rich plant foods like legumes and vegetables do not increase the risk of gout. The current dietary guidelines take into account nutritional factors, which not only consider purine intake, but also their endogenous production and their influence on renal excretion. A balanced diet based on the Swiss healthy eating guideline pyramid as well as the Mediterranean diet is appropriate for this patient population. The treatment of gout is multi-faceted, since this patient population presents other comorbidities such as obesity, diabetes mellitus, dyslipidemia and hypertension. Collectively, these risk factors are diet dependent and require a treatment strategy that is centered on modifying one's nutrition and nutritional behaviours. The aim of such therapy is to educate the patient as well as treat the accompanying comorbidities with the goal of decreasing serum uric acid values. Motivated patients require consultation and follow-up care in order to be able to actively decrease the serum uric acid.

Although previous nutrition interventions involving peer mentoring of youth have been successful, there is a lack of studies evaluating the influence of cross-age peers within interventions targeting youth. This article evaluates the implementation of the BHCK intervention in recreation centers, and describes lessons learned. Sixteen youth leaders delivered bi-weekly, interactive sessions to 10- to 14-y olds. Dose, fidelity and reach are assessed, as is qualitative information regarding what worked well during sessions. Dose is operationalized as the number of interactive sessions, and taste tests, giveaways and handouts per session; fidelity as the number of youth leaders participating in the entire intervention and per session and reach as the number of interactions with the target population. Based on a priori set values, number of interactive sessions was high, and number of taste tests, giveaways and handouts was moderate to high (dose). The number of participating youth leaders was also high (fidelity). Of the 14 planned sessions, the intervention was implemented with high/moderate reach. Data suggest that working with cross-age peers is a promising nutritional intervention for recreation centers.

  1. Crafting regulations in emerging geothermal countries: The Peru example

    SciTech Connect

    Armstrong, A.J.

    1996-12-31

    Conventional wisdom holds that no prudent investor or lender will ante up a penny of investment money in a geothermal project unless and until there is a geothermal resources law in place. Since every law depends on a regulatory regime to make the law work in actual practice, implemented regulations are equally important conditions precedent for geothermal development. In recognition of the importance of assisting geothermal regulatory development in the emerging geothermal countries of Latin America, during the 1995 to 1996 timeframe, the Geothermal Energy Association has acted in an advisory capacity to the Ministry of Energy and Mines of Peru, in the drafting of geothermal regulations for Peru. These regulations are designed to promote developmental investment in the geothermal resources of Peru, while simultaneously establishing reasonable standards for the protection of the people and the environment of the country. While these regulations are specific to Peru, they may well serve as a model for other countries of Latin America. Thus, the lessons learned in crafting the Peru regulatory regime may have applicability in other countries in which the geothermal industry is now working or may work in the future.

  3. Mass media in Peru promotes "responsible parenthood".

    PubMed

    Brace, J; Pareja, R

    1985-01-01

    This article describes a media campaign being carried out in Peru under the auspices of the Ministry of Health. The overall theme of the campaign is Responsible Parenthood, specifically in the areas of family planing, oral rehydration, and immunization. The mass media campaign was based on the results of extensive audience research data that identified knowledge and beliefs in these areas. The research identified 2 target audiences for family planning messages: those who want no more children and those who are using traditional contraceptive methods. In addition to quantitative audience surveys, focus group discussions were held. These groups revealed important information about contraceptive habits, male attitudes toward family planning, and the folk vocabulary used for family planning activities. They further suggested that the quality of services given in health centers affects future use of that service and that the most credible source of information about family planning is considered to be a mature female doctor, herself a mother. Pretesting of television spots for the campaign was valuable for identifying unacceptable or ineffective images. It was also learned that radio and telvision spots cannot be the same; rather, they require unique content.

    In 1969, two consecutive earthquakes activated a reverse fault at an elevation of 4600 m in the Huaytapallana mountain range near Huancayo in central Peru. In 1975, a small geodetic network was established and measured across the fault covering an area of about 1.5 km 2. The network has been remeasured in 1976, 1977, 1978, and 1982, using standard geodetic instruments, as a joint effort by two Canadian and one German universities in cooperation with the Peruvian Institute of Geophysics. In 1978, the network was expanded to cover 6 km 2. High-altitude sickness, logistic problems with old vehicles, civil unrest and riots plagued the survey expeditions. The results show a cyclic rigid body motion of the southwest side versus the northeast side of the fault in a general east-west direction of about ± 3 mm/year. The direction of the motion agrees with the direction of compressive forces expected in this subduction region. The next survey campaign is planned for 1987.

    2015-10-01

    Stem cells are defined as rare cells that are characterized by asymmetric division, a process known as self-renewal, and the potential to differentiate into more than one type of terminally differentiated cell. There is a diversity of stem cells including embryonic stem cells, which exist only during the first stages of human development, and many adult stem cells depending on the specific tissues from where they derive or the ones derived from mesenchymal or stromal tissues. On the other hand, there are induced pluripotent stem cells generated by genetic engineering with similar properties to embryonic stem cells that are derived from adult tissues without the ethical and legal limitations. In all cases, there are many questions that are being addressed by research in basic sciences to better inform clinical practice. In Peru, there is much to do refining techniques and improving methodologies, which requires experience, proper facilities and highly specialized human resources. However, there are interesting efforts to place Peruvian stem cell research in the international scientific arena.

    1993-01-01

    In Peru pork supplied through regulated slaughterhouses is primarily restricted to the large cities on the coast. Approximately 65% of the pork consumed in the country is obtained through informal channels that are not inspected or supervised. The pathways via which pigs are commercialized were studied in Huancayo, a city in the Peruvian Sierra where cysticercosis is endemic. Official purchase, slaughter, and market records were reviewed. Also, direct surveys and participant observation were carried out at two local live pig markets and at two informal meat markets. Pigs were not processed in local slaughterhouses; instead, they were butchered informally. The proportion of cysticercotic pigs detected by tongue examination ranged from 14% to 25% of the total sold. Since cysticercotic pigs and pork are sold through informal markets, surveys of abattoirs and meat markets are not a reliable way to monitor the prevalence of porcine cysticercosis in Peru. We estimate that 48% of the pork traded informally and 23% of the total pork consumed in Huancayo is derived from pigs that are infected with cysticercosis. PMID:8490986

    Classical swine fever (CSF) is considered to be endemic in Peru with outbreaks reported to the World Organization for Animal Health as recently as 2008 and 2009. Nevertheless, little is known regarding the genetic subgroup(s) of CSF virus that are circulating in Peru or their relationship to recent CSF viruses that have been isolated from neighbouring South American countries or other parts of the world. In this study, we molecularly characterize CSF viruses that were isolated from domestic pigs from different regions of Peru from the middle of 2007 to early 2008. All virus isolates were found to belong to genetic subgroup 1.1, consistent with the subgroup of viruses that have been identified from other South American countries. Although the Peruvian isolates are most closely related to viruses from Colombia and Brazil, they form a monophyletic clade, which suggests they have a distinct evolutionary history.

    The genus Eumops is the most diverse genera of molossid bats in the Neotropics. In Peru this genus is widely distributed and represented by nine species: E. auripendulus, E. delticus, E. hansae, E. maurus, E. nanus, E. patagonicus, E. perotis, E. trumbulli, and E. wilsoni. After several years of mammalian diversity surveys in the coastal desert and western slopes of southwestern Peru, a specimen of Eumops was collected whose unique set of traits allows us to assert that deserves to be described as a new species. Based on molecular and morphological evidence, the new species is related to medium-large sized species (i.e. E. glaucinus, E. auripendulus, and E. perotis). Cytochrome b genetic divergence between the new species and the other species of the genus was high (> 12%) and it is consistent with morphological divergence presented for this new species. This new species, endemic to Peru, increases the diversity of Eumops to 16 species.

    Summary Female sex workers (FSWs) are at high risk of human papillomavirus (HPV) infection. Questionnaires were administered to 200 FSWs aged 18–26 years in Lima, Peru, to gather risk behaviours, and cervical swab samples were collected for Pap smears and HPV DNA testing as part of a longitudinal study. Participants reported a median of 120 clients in the past month, and 99.2% reported using condoms with clients. The prevalence of any HPV in cervical samples was 66.8%; 34 (17.1%) participants had prevalent HPV 16 or 18, and 92 (46.2%) had one or more oncogenic types. Fifteen women had abnormal Pap smears, 13 of which were HPV DNA positive. Fewer years since first sex was associated with oncogenic HPV prevalence in a model adjusted for previous sexually transmitted infection (STI) status and condom use with partners (prevalence ratio = 0.77, 95% confidence interval [CI] = 0.60–0.97). Our data confirm the high rates of HPV transmission among FSWs in Peru, highlighting the need for early and effective strategies to prevent cervical cancer. PMID:22581946

    Well-trained people are urgently needed to tackle global health challenges through information and communication technologies. In this report, AMAUTA, a joint international collaborative training program between the Universidad Peruana Cayetano Heredia and the University of Washington, which has been training Peruvian health professionals in biomedical and health informatics since 1999, is described. Four short-term courses have been organized in Lima, offering training to more than 200 graduate-level students. Long-term training to masters or doctorate level has been undertaken by eight students at the University of Washington. A combination of short-term and long-term strategies was found to be effective for enhancing institutional research and training enterprise. The AMAUTA program promoted the development and institution of informatics research and training capacity in Peru, and has resulted in a group of trained people playing important roles at universities, non-government offices, and the Ministry of Health in Peru. At present, the hub is being extended into Latin American countries, promoting South-to-South collaborations. PMID:20595317

    2016-11-01

    Obesity is a common disorder with complex causes. The epidemic has spurred significant advances in the understanding of nutritional approaches to treating obesity. Although the primary challenge is to introduce a dietary intake that creates an energy deficit, clinicians should also consider targeted risk factor modification with manipulation of the nutrient profile of the weight-reducing diet. These strategies produce significant weight loss and improvements in cardiometabolic risk factors. Future research is needed to better understand how to personalize nutrient prescriptions further to promote optimal risk modification and maintenance of long-term energy balance in the weight-reduced state.

  17. Pediatric Parenteral Nutrition-Associated Liver Disease.

    PubMed

    Israelite, Jill C

    Pediatric parenteral nutrition-associated liver disease (PNALD) is typically defined as a decrease in bile flow that is independent of a mechanical obstruction and of any other underlying liver disease. It is most often seen in pediatric patients receiving parenteral nutrition support. Up to 50% to 66% of children receiving long-term parenteral nutrition are reported to be diagnosed with PNALD. The goal of treatment for PNALD is advancement to full enteral nutrition and elimination of dependence on parenteral nutrition support. Achieving this goal is not always possible, especially in patients with short bowel syndrome. The following review article highlights some of the current treatment strategies focused on prevention or correction of PNALD as noted in current American Society for Parenteral and Enteral Nutrition guidelines.

    Tungiasis is a neglected ectoparasitism of impoverished areas in South America and sub-Saharan Africa. The sand flea Tunga spp. preferably infests the soles and the periungueal and interdigital regions of the feet. Ectopic tungiasis is rare, even in highly endemic areas. We describe a case of an indigenous patient in Peru who presented with a nodular lesion in the extensor aspect of the knee and whose biopsy was compatible with Tunga spp. This is the first documented case of knee tungiasis in an endemic country. The historical, clinical, histological, and current epidemiological aspects of tungiasis in Peru are discussed here. PMID:20519602

    wetland habitats throughout their annual cycles. Survival, reproduction, and growth are dependent on the availability of foods that meet nutritional requirements for recurring biological events. These requirements occur among a wide variety of environmental conditions that also influence nutritional demands. Recent work on nesting waterfowl has identified the female’s general nutrient needs for egg laying and incubation. Far less is known about nutritional requirements for molt and other portions of the life cycle, particularly those during the nonbreeding season. Although information on specific requirements for amino acids and micronutrients of wild birds is meager, the available information on waterfowl requirements can be used to develop waterfowl management strategies. For example, nutrient content of foods, nutritional requirements of waterfowl, and the cues waterfowl use in locating and selecting foods are all kinds of information that managers need to encourage use of habitats by feeding waterfowl. Waterfowl nutritional needs during the annual cycle and the nutritional values of natural foods and crops will be discussed below.

    The climate variability and change will have increasing influence on the economic and social development of all countries and regions, such as the Andes in Latin America. The CLIMANDES project (Climate services to support decision-making in the Andean Region) will address these issues in Peru. CLIMANDES supports the WMO Regional Training Centre (RTC) in Lima, which is responsible for the training of specialized human resources in meteorology and climatology in the South American Andes (Module 1). Furthermore, CLIMANDES will provide high-quality climate services to inform policy makers in the Andean region (Module 2). It is coordinated by the World Meteorological Organization (WMO) and constitutes a pilot project under the umbrella of the WMO-led Global Framework for Climate Services (GFCS). The project is funded by the Swiss Agency for Development and Cooperation (SDC) and runs from August 2012 - July 2015. Module 1 focuses on restructuring the curricula of Meteorology at the La Molina Agraria University (UNALM) and applied training of meteorologists of the Peruvian National Service of Meteorology and Hydrology (SENAMHI). In Module 2, the skills will be shared and developed in the production and delivery of high-quality climate products and services tailored to the needs of the decision makers in the pilot regions Cusco and Junín. Such services will benefit numerous sectors including agriculture, education, health, tourism, energy, transport and others. The goals of the modules 1 and 2 will be achieved through the collaboration of the UNALM, SENAMHI and the Federal Office of Meteorology and Climatology MeteoSwiss, with the support of the University of Bern (UNIBE), Meteodat and WMO.

We will also discuss the validity of the status given the neglect of health surveillance, disbanded specialized control entities, health medical staff forgetting to account for leprosy in early stages, the presence of undiagnosed smear-positive leprosy in Lima and the undeniable hidden prevalence, suggest that there is a danger to the country and the region that a re-emergence of leprosy will occur, if relevant and appropriate sanitary measures are not taken.

  2. Nutritional Supplements to Enhance Recovery

    The ability to recover from intense exercise often separates good athletes from great ones. In the past, "recovery" often simply included rest, physical modalities (e.g., massage, hydration therapy) and meeting basic nutritional needs for fluid and energy intake. Today, athletes have a number of additional options to help them recover from high intensity training, one of which includes the judicious use of dietary supplements. This chapter briefly reviews nutritional strategies that have a strong theoretical background for enhancing rehydration/electrolyte balance, replenishing energy reserves, minimizing oxidative damage, and stimulating muscle repair.

    according to 744 different uses (Tyrol: 552, Australia: 200, Brazil: 180, Peru: 357) belonging to 22 different categories of use. Use values are significantly different between Tyrol and Australia (p < 0.001) but not between Tyrol and Brazil (p = 0.127) and Tyrol and Peru (p = 0.853). The average informant agreement ratio (IAR) in Tyrol is significantly higher than in Australia (p = 0.089) and Brazil (p = 0.238), but not Peru (p = 0.019). Conclusions Changing ecological and social conditions have transformed and shaped traditional knowledge of medicinal plants through adaptation processes to match the new circumstances in the country of arrival. Continuation, substitution and replacement are strategies that have taken place at different rates depending on local circumstances in the research areas. Traditional knowledge of medicinal plants acquired in the home country is continuously diminishing, with its composition influenced by urbanisation and ongoing globalisation processes and challenged by shifts from traditional healing practices to modern healthcare facilities.

    Bacillus spp. are well known rhizosphere residents of many crops and usually show plant growth promoting (PGP) activities that include biocontrol capacity against some phytopatogenic fungi. Potato crops in the Andean Highlands of Peru face many nutritional and phytophatogenic problems that have a significant impact on production. In this context is important to investigate the natural presence of these microorganisms in the potato rhizosphere and propose a selective screening to find promising PGP strains. In this study, sixty three Bacillus strains isolated from the rhizosphere of native potato varieties growing in the Andean highlands of Peru were screened for in vitro antagonism against Rhizoctonia solani and Fusarium solani. A high prevalence (68%) of antagonists against R. solani was found. Ninety one percent of those strains also inhibited the growth of F. solani. The antagonistic strains were also tested for other plant growth promotion activities. Eighty one percent produced some level of the auxin indole-3-acetic acid, and 58% solubilized tricalcium phosphate. Phylogenetic analysis revealed that the majority of the strains belonged to the B. amyloliquefaciens species, while strains Bac17M11, Bac20M1 and Bac20M2 may correspond to a putative new Bacillus species. The results suggested that the rhizosphere of native potatoes growing in their natural habitat in the Andes is a rich source of Bacillus fungal antagonists, which have a potential to be used in the future as PGP inoculants to improve potato crop.

    Social capital has been shown to be positively associated with a range of health outcomes, yet no studies have explored the association between maternal social capital and child nutritional status. Using data from the Young Lives study comprising 7242 1-year-old children from Peru, Ethiopia, Vietnam and the state of Andhra Pradesh in India, we find significant differences in the levels of, in particular, structural social capital (group membership and citizenship) between countries. While few associations were found between structural measures of social capital, support from individuals and cognitive social capital (e.g. trust, social harmony) displayed fairly consistent positive associations with child nutritional status across countries.

  7. Nutritional aspects of depression.

    2015-01-01

    Several nutrition, food and dietary compounds have been suggested to be involved in the onset and maintenance of depressive disorders and in the severity of depressive symptoms. Nutritional compounds might modulate depression associated biomarkers and parallel the development of depression, obesity and diabetes. In this context, recent studies revealed new mediators of both energy homeostasis and mood changes (i.e. IGF-1, NPY, BDNF, ghrelin, leptin, CCK, GLP-1, AGE, glucose metabolism and microbiota) acting in gut brain circuits. In this context several healthy foods such as olive oil, fish, fruits, vegetables, nuts, legumes, poultry, dairy and unprocessed meat have been inversely associated with depression risk and even have been postulated to improve depressive symptoms. In contrast, unhealthy western dietary patterns including the consumption of sweetened beverage, refined food, fried food, processed meat, refined grain, and high fat diary, biscuits, snacking and pastries have been shown to be associated with an increased risk of depression in longitudinal studies. However, it is always difficult to conclude a real prospective causal relationship from these mostly retrospective studies as depressed individuals might also change their eating habits secondarily to their depression. Additionally specific selected nutritional compounds, e.g. calcium, chromium, folate, PUFAs, vitamin D, B12, zinc, magnesium and D-serine have been postulated to be used as ad-on strategies in antidepressant treatment. In this context, dietary and lifestyle interventions may be a desirable, effective, pragmatical and non-stigmatizing prevention and treatment strategy for depression. At last, several medications (pioglitazone, metformin, exenatide, atorvastatin, gram-negative antibiotics), which have traditionally been used to treat metabolic disorders showed a certain potential to treat depression in first randomized controlled clinical trials.

    Cardiovascular disease (CVD) is a universal problem in modern society. Atherosclerosis is the leading cause of CVD resulting in high rate of mortality in the population. Nutrition science has focused on the role of essential nutrients in preventing deficiencies, at the present time, the nutritional strategies are crucial to promote health and intervene with these global noncommunicable diseases. In many cases, diet is a major driving force, which is much easier to change and follow than other factors. It is important to establish that the first strategy to treat atherosclerosis is to modify lifestyle habits, focusing on the beneficial properties of specific nutrients. In the last decades, epidemiological, clinical and experimental studies have demonstrated that diet plays a central role in the prevention of atherosclerosis. In this review we will focus on the effect of specific foods, nutrients and bioactive compounds, including epidemiological facts, potential mechanisms of action and dietary recommendations to reduce the risk of atherosclerosis. In particular, we include information about fiber, plant sterols and stanols, niacin, taurine, olive oil, omega 3 fatty acids, antioxidants, minerals, methyl nutrients and soy. In addition, we also show that dysbiosis of the intestinal microbiota associated with a consumption of certain animal food sources can generate some metabolites that are involved in the development of atherosclerosis and its consequences on CVD. According to the epidemiological, clinical and experimental studies we suggest a recommendation for some dietary foods, nutrients and bioactive compounds to support the complementary clinical management of patients with atherosclerosis.

    Background Cervical cancer, although usually preventable by Pap smear screening, remains the leading cause of cancer-related deaths among women in Peru. The percentages and characteristics of women in Peru who have or have not had a Pap smear have not been defined. Methods In an urban community randomized trial of sexually transmitted infection (STI)/HIV prevention in Peru, 6712 randomly selected women between the ages of 18 and 29 from 20 cities were interviewed regarding having had cervical Pap smears. Results Among women sampled, only 30.9% had had a Pap smear. By multivariate analysis, the main predictors of having a Pap smear were having had sex, having had children, completion of secondary education and increasing age. Regional variations were also found: women from the highlands and rainforest were less likely to have had Pap smears than women from the coast. Conclusion A norm of seeking and receiving Pap smears has not been established among sexually active young Peruvian women. To improve Pap smear coverage in Peru, promotion efforts should target underserved women and regions with less coverage. PMID:18653515

  4. Geriatric nutrition.

    PubMed

    Markham, R W; Hodgkins, E M

    1989-01-01

    In recent decades, veterinary medicine has become more successful in prolonging the healthy, useful lives of pets. As a result, the practitioner spends a greater part of each practice day caring for the geriatric animal, both healthy and unhealthy. Because of their longevity, older pets are typically regular family members, with owners who seek the finest health care possible for their pets. The practice of geriatric medicine most properly should begin not when the dog or cat reaches some specific "golden" age, but rather when the wiggly, robust puppy or kitten receives its first examination. Like all parts of a sound preventive program, geriatric nutrition best follows from a well-considered juvenile and adult nutrition program. Furthermore, once it becomes senior, the "well" geriatric is as much a candidate for a diet designed especially to accommodate old age changes as is his unhealthy contemporary. In fact, evidence suggests that appropriate dietary management of the healthy, but often subclinical, patient may help postpone the signs of dysfunction and increase quality and length of life. A knowledge of the most significant nutrients and the impact of each on aging systems is now, and will become increasingly more, important to the progressive, skillful veterinarian.

  5. Reservoir storage and irrigation in Arequipa, Peru

    NASA Astrophysics Data System (ADS)

    Ertsen, Maurits; Swiech, Theoclea; Machicao Pererya, Carlos

    2010-05-01

    In countries such as Peru, irrigated agriculture is not only vital for the subsistence of many but can also be a factor of economic development and by extent social improvement. To answer the local demand and respond to the water scarcity in the sub-basin of Yarabamba, near city of Arequipa, the government decided the construction of a dam for irrigation. The irrigation systems are affected by the lack of water during the dry season for lack of storage and of water distribution between downstream and upstream sectors, among other issues. Water scarcity is the main issue in the basin, leading to poor yields and the inability of growing crops with a high commercial value. Rainfall is available only from November to April, the rest of the year being very dry. Furthermore, the lowest areas of Yarabamba, Sogay and Quequeña are disadvantaged compared to the highest area of Polobaya. By creating a large storage area to regulate the variations of water availability through the year, the dam would allow to at least palliate the lack of water in existing lands, and at best to extend agricultural lands. Farmers would then be able to shift toward higher value crops more easily than without this extra storage. The main focus of the research was the dam which was supposed to improve the water distribution and availability in the sub-basin. From the results of the study, it can be concluded that other factors, related to the irrigation system itself, are involved in the efficiency of the new structure. The farmers, the main stakeholders, believe that more could be done to improve the system and their standard of living. Most of all, the main issue that should be resolved is the fair distribution of water. However, this is not possible without a strong cooperation between sectors, and a potential change in diversion structures. The competition between the districts should be reduced, otherwise the benefits of the dam would not give the expected results. This example shows that

    2003-11-01

    We determine the spatial pattern of Aedes aegypti and the containers in which they develop in two neighborhoods of the Amazonian city of Iquitos, Peru. Four variables were examined: adult Ae. aegypti, pupae, containers positive for larvae or pupae, and all water-holding containers. Adults clustered strongly within houses and weakly to a distance of 30 meters beyond the household; clustering was not detected beyond 10 meters for positive containers or pupae. Over short periods of time restricted flight range and frequent blood-feeding behavior of Ae. aegypti appear to be underlying factors in the clustering patterns of human dengue infections. Permanent, consistently infested containers (key premises) were not major producers of Ae. aegypti, indicating that larvaciding strategies by themselves may be less effective than reduction of mosquito development sites by source reduction and education campaigns. We conclude that entomologic risk of human dengue infection should be assessed at the household level at frequent time intervals.

  8. Nutritional Supplements for Endurance Athletes

    NASA Astrophysics Data System (ADS)

    Rasmussen, Christopher J.

    Athletes engaged in heavy endurance training often seek additional nutritional strategies to help maximize performance. Specific nutritional supplements exist to combat certain factors that limit performance beginning with a sound everyday diet. Research has further demonstrated that safe, effective, legal supplements are in fact available for today's endurance athletes. Several of these supplements are marketed not only to aid performance but also to combat the immunosuppressive effects of intense endurance training. It is imperative for each athlete to research the legality of certain supplements for their specific sport or event. Once the legality has been established, it is often up to each individual athlete to decipher the ethics involved with ingesting nutritional supplements with the sole intent of improving performance.

    Nutritional quality during the first weeks of life can influence health during both infancy and adulthood. Exclusive long-term breast feeding is strongly recommended, particularly for infants at risk of allergy. It protects against gastrointestinal and respiratory infections, and has been shown to enhance cognitive and intellectual development. Breast-feeding is also associated with a lower risk of obesity and type 1 diabetes in infants and of cardiovascular disease in adults. Breast-feeding is rarely contraindicated. Multiple European and French guidelines and regulations govern the composition of infant formulas, which may be given during the first year of life when breast-feeding is unavailable. Hypoallergenic and soy-based formulas are not recommended for healthy infants.

    Most clinicians believe that nutrition support therapy improves outcome in hospitalized patients. Unfortunately, few patients receive optimal nutrition management. A lack of strong, well-designed research studies may prevent the medical/surgical community from fully embracing the practice. More quality research is needed. This article discusses 3 potential strategies to improve research activity in clinical nutrition: increase funding of nutrition research, foster young physician training in nutrition and research, and attract nutrition researchers to our national nutrition society meetings. The best chance for this process to succeed is for the national nutrition societies to partner with medical and surgical subspecialty societies to develop larger scale clinical and translational research programs.

    Precision nutrition encompasses prevention and treatment strategies for optimizing health that consider individual variability in diet, lifestyle, environment and genes by accurately determining an individual's nutritional status. This is particularly important as malnutrition now affects a third of the global population, with most of those affected or their care providers having limited means of determining their nutritional status. Similarly, program implementers often have no way of determining the impact or success of their interventions, thus hindering their scale-up. Exciting new developments in the area of point-of-care diagnostics promise to provide improved access to nutritional status assessment, as a first step towards enabling precision nutrition and tailored interventions at both the individual and community levels. In this review, we focus on the current advances in developing portable diagnostics for assessment of nutritional status at point-of-care, along with the numerous design challenges in this process and potential solutions.

  12. Nutritional recommendations for water polo.

    Water polo is an aquatic team sport that requires endurance, strength, power, swimming speed, agility, tactical awareness, and specific technical skills, including ball control. Unlike other team sports, few researchers have examined the nutritional habits of water polo athletes or potential dietary strategies that improve performance in water polo match play. Water polo players are typically well muscled, taller athletes; female players display higher levels of adiposity compared with their male counterparts. Positional differences exist: Center players are heavier and have higher body fat levels compared with perimeter players. Knowledge of the physical differences that exist among water polo players offers the advantage of player identification as well as individualizing nutrition strategies to optimize desired physique goals. Individual dietary counseling is warranted to ensure dietary adequacy, and in cases of physique manipulation. Performance in games and during quality workouts is likely to improve by adopting strategies that promote high carbohydrate availability, although research specific to water polo is lacking. A planned approach incorporating strategies to facilitate muscle glycogen refueling and muscle protein synthesis should be implemented following intensified training sessions and matches, particularly when short recovery times are scheduled. Although sweat losses of water polo players are less than what is reported for land-based athletes, specific knowledge allows for appropriate planning of carbohydrate intake strategies for match play and training. Postgame strategies to manage alcohol intake should be developed with input from the senior player group to minimize the negative consequences on recovery and player welfare.

    The β-nicotinamide adenine dinucleotide (NAD) requirement has been considered to be essential for the isolation of the causal agent of infectious coryza, Avibacterium paragallinarum. Nevertheless, NAD-independent reports from South Africa and Mexico dismissed this paradigm. It is now accepted that both NAD-dependent and NAD-independent agents are able to cause infectious coryza and thus belong to the species A. paragallinarum. Here, we report for the first time in Peru a NAD-independent isolate from broiler chickens with typical signs of infectious coryza that have received a trivalent inactivated vaccine against infectious coryza. The isolate was identified based on its morphology, biochemical and serologic tests, and PCR results. Partial 16S rRNA gene sequence analysis confirmed the isolate as A. paragallinarum. There have been no cases of NAD-independent A. paragallinarum isolates reported in South America. Increasing reports around the world highlight not only the need to reconsider the in vitro nutritional requirements of this species for its correct isolation but also the cross-protection conferred by commercial infectious coryza vaccines against NAD-independent isolates.

  16. Cost-effectiveness and cost utility analysis of three pneumococcal conjugate vaccines in children of Peru

    2013-01-01

    Background The clinical and economic burden associated with invasive and non-invasive pneumococcal and non-typeable Haemophilus influenzae (NTHi) diseases is substantial in the Latin America and Caribbean region, where pneumococcal vaccines have only been introduced to a few countries. This study analyzed the cost-effectiveness and cost utility of three different pneumococcal conjugate vaccines (PCVs) for Peru. Methods A Markov model that simulated the disease processes in a birth cohort over a lifetime, within 1,128 month cycles was used to evaluate the cost-effectiveness of 10-valent pneumococcal NTHi protein D conjugate vaccine (PHiD-CV) and 7- and 13-valent PCVs (PCV-7 and PCV-13). Expected quality-adjusted life years (QALYs), cost-savings and incremental cost-effectiveness ratios (ICERs) were calculated. Results Without vaccination, pneumonia was associated with the greatest health economic burden (90% of QALYs lost and 63% of lifetime direct medical costs); while acute otitis media (AOM) was responsible for 1% of QALYs lost and 25% of direct medical costs. All vaccines were predicted to be cost-effective for Peru, with PHiD-CV being most cost-effective. PHiD-CV was predicted to generate 50 more QALYs gained and required a reduced investment (−US$ 3.4 million) versus PCV-13 (discounted data), and was therefore dominant and cost saving. The probabilistic sensitivity analysis showed that PHiD-CV generated more QALYs gained at a reduced cost than PCV-13 in 84% of the simulations and less QALYs gains at a reduced cost in 16%. Additional scenarios using different assumptions on vaccine efficacies based on previous evidence were explored, but no significant change in the overall cost-effective results were observed. Conclusions The results of this modeling study predict that PCVs are likely to be a cost-effective strategy to help relieve the epidemiological and economic burden associated with pediatric pneumococcal and NTHi diseases for Peru. PHiD-CV is likely

    Team sports are based on intermittent high-intensity activity patterns, but the exact characteristics vary between and within codes, and from one game to the next. Despite the challenge of predicting exact game demands, performance in team sports is often dependent on nutritional factors. Chronic issues include achieving ideal levels of muscle mass and body fat, and supporting the nutrient needs of the training program. Acute issues, both for training and in games, include strategies that allow the player to be well fuelled and hydrated over the duration of exercise. Each player should develop a plan of consuming fluid and carbohydrate according to the needs of their activity patterns, within the breaks that are provided in their sport. In seasonal fixtures, competition varies from a weekly game in some codes to 2-3 games over a weekend road trip in others, and a tournament fixture usually involves 1-3 days between matches. Recovery between events is a major priority, involving rehydration, refuelling and repair/adaptation activities. Some sports supplements may be of value to the team athlete. Sports drinks, gels and liquid meals may be valuable in allowing nutritional goals to be met, while caffeine, creatine and buffering agents may directly enhance performance.

    The goal of training is to prepare the distance athlete to perform at his or her best during major competitions. Whatever the event, nutrition plays a major role in the achievement of various factors that will see a runner or walker take the starting line in the best possible form. Everyday eating patterns must supply fuel and nutrients needed to optimize their performance during training sessions and to recover quickly afterwards. Carbohydrate and fluid intake before, during, and after a workout may help to reduce fatigue and enhance performance. Recovery eating should also consider issues for adaptation and the immune system that may involve intakes of protein and some micronutrients. Race preparation strategies should include preparation of adequate fuel stores, including carbohydrate loading for prolonged events such as the marathon or 50-km walk. Fluid and carbohydrate intake during races lasting an hour or more should also be considered. Sports foods and supplements of value to distance athletes include sports drinks and liquid meal supplements to allow nutrition goals to be achieved when normal foods are not practical. While caffeine is an ergogenic aid of possible value to distance athletes, most other supplements are of minimal benefit.

    Osteoporosis is a debilitating disease that affects many older people. Fragility fractures are the hallmark of osteoporosis. Although nutrition is only 1 of many factors that influence bone mass and fragility fractures, there is an urgent need to develop and implement nutritional approaches and policies for the prevention and treatment of osteoporosis that could, with time, offer a foundation for population-based preventive strategies. However, to develop efficient and precocious strategies in the prevention of osteoporosis, it is important to determine which modifiable factors, especially nutritional factors, are able to improve bone health throughout life. There are potentially numerous nutrients and dietary components that can influence bone health, and these range from the macronutrients to micronutrients as well as bioactive food ingredients. The evidence-base to support the role of nutrients and food components in bone health ranges from very firm to scant, depending on the nutrient/component. This article initially overviews osteoporosis, including its definition, etiology, and incidence, and then provides some information on possible dietary strategies for optimizing bone health and preventing osteoporosis. The potential benefits of calcium, vitamin D, vitamin K(1), phytoestrogens, and nondigestible oligosaccharides are briefly discussed, with particular emphasis on the evidence base for their benefits to bone. It also briefly considers some of the recent findings that highlight the importance of some dietary factors for bone health in childhood and adolescence.

  20. Ferret nutrition.

    PubMed

    1999-01-01

    The unusually short intestinal tract of ferrets and closely related mustelids lacks a cecum and ileocolic valve. As a result, the transit time of ingesta in these carnivores is very rapid compared with other animals, and their food is inefficiently digested. Although the precise nutritional requirements of ferrets have not been determined by feeding defined diets, information has been compiled from experience feeding commercial and analyzed homemade diets to breeding ferrets, fitch, and mink at all stages of their lives. The requirements of spayed or neutered pet ferrets are met by allowing them constant access to drinking water and a palatable, pelleted, or extruded, 90% dry matter, premium cat or ferret food that, as fed, contains at least 15% fat and 30% high quality, meat source protein, less than 30% carbohydrates, and approximately 4 Kcal of metabolizable energy per gram. Lower density diets with more carbohydrate and less protein are associated with poor reproductive performance and growth and greater susceptibility to infectious and metabolic diseases.

    The tantalizing potential of nanotechnology is to fabricate and combine nanoscale approaches and building blocks to make useful tools and, ultimately, interventions for medical science, including nutritional science, at the scale of approximately 1-100 nm. In the past few years, tools and techniques that facilitate studies and interventions in the nanoscale range have become widely available and have drawn widespread attention. Recently, investigators in the food and nutrition sciences have been applying the tools of nanotechnology in their research. The Experimental Biology 2009 symposium entitled "Nanotechnology Research: Applications in Nutritional Sciences" was organized to highlight emerging applications of nanotechnology to the food and nutrition sciences, as well as to suggest ways for further integration of these emerging technologies into nutrition research. Speakers focused on topics that included the problems and possibilities of introducing nanoparticles in clinical or nutrition settings, nanotechnology applications for increasing bioavailability of bioactive food components in new food products, nanotechnology opportunities in food science, as well as emerging safety and regulatory issues in this area, and the basic research applications such as the use of quantum dots to visualize cellular processes and protein-protein interactions. The session highlighted several emerging areas of potential utility in nutrition research. Nutrition scientists are encouraged to leverage ongoing efforts in nanomedicine through collaborations. These efforts could facilitate exploration of previously inaccessible cellular compartments and intracellular pathways and thus uncover strategies for new prevention and therapeutic modalities.

  2. The history of 20th century malaria control in Peru

    2013-01-01

    Malaria has been part of Peruvian life since at least the 1500s. While Peru gave the world quinine, one of the first treatments for malaria, its history is pockmarked with endemic malaria and occasional epidemics. In this review, major increases in Peruvian malaria incidence over the past hundred years are described, as well as the human factors that have facilitated these events, and concerted private and governmental efforts to control malaria. Political support for malaria control has varied and unexpected events like vector and parasite resistance have adversely impacted morbidity and mortality. Though the ready availability of novel insecticides like DDT and efficacious medications reduced malaria to very low levels for a decade after the post eradication era, malaria reemerged as an important modern day challenge to Peruvian public health. Its reemergence sparked collaboration between domestic and international partners towards the elimination of malaria in Peru. PMID:24001096

    We use data from the recent PeruSE seismic experiment in southern Peru to compare the variation in properties between the normal-dip portion of the subduction interface and the flat slab-mantle interface. The analysis includes migration of the receiver functions to determine the variations in shear and compressional velocities, and the detail measurements of along amplitudes of the receiver-function images. Converted amplitudes at the top and bottom of the Nazca oceanic crust are used to constrain shear wave velocity and density of the subducted crust, and these values are compared to those determined from the experimental mineral physics. We also separately examine the stations closest to the coast to explore how structural variations near the plate interface can be linked to along-strike change in frictional behavior in the seismogenic zone. The results will be compared to the flat subduction zones in Mexico and central Chile.

    While numerous studies have explored young people's sexual behaviour in Peru, to date few have explored how adolescents situate sexuality within the context of their broader lives. This information is needed to inform policies and programmes. Life history interviews were conducted with 20 12-17-year-old young women and men from a low-income settlement near Lima, Peru. Data were analysed using holistic content analysis and grounded theory. Sexuality had a strong presence in respondents' lives. However, interviewees viewed the full expression of their sexuality as a constrained choice. Particular constraints derive from the belief that sexual intercourse always results in pregnancy; the nature of sex education; the provision of proscriptive advice; and the family tensions, economic problems, racism and violence present in young people's lives. The results of this study can inform policies and programmes to support young people as they make sexuality-related decisions.

    Guaroa virus (GROV) was first isolated from humans in Colombia in 1959. Subsequent isolates of the virus have been recovered from febrile patients and mosquitoes in Brazil, Colombia, and Panama; however, association of the virus with human disease has been unclear. As part of a study on the etiology of febrile illnesses in Peru and Bolivia, 14 GROV strains were isolated from patients with febrile illnesses, and 3 additional cases were confirmed by IgM seroconversion. The prevalence rate of GROV antibodies among Iquitos residents was 13%; the highest rates were among persons with occupations such as woodcutters, fisherman, and oil-field workers. Genetic characterization of representative GROV isolates indicated that strains from Peru and Bolivia form a monophyletic group that can be distinguished from strains isolated earlier in Brazil and Colombia. This study confirms GROV as a cause of febrile illness in tropical regions of Central and South America. PMID:20810845

This article uses findings from 185 direct clinician observations in four cities of Peru (representing the capital and each of the three main geographic regions of the country) to assess missed opportunities for health education on Pap smears and other preventive women’s health behaviors during women’s visits to a health care provider. Various types of health establishments, provider settings, and provider types were observed. Opportunities for patient education on the importance of prevention were rarely exploited. In fact, health education provided was minimal. Policy and programmatic implications are discussed. PMID:21464205

    Few supplement combinations that are marketed to athletes are supported by scientific evidence of their effectiveness. Quite often, under the rigor of scientific investigation, the patented combination fails to provide any greater benefit than a group given the active (generic) ingredient. The focus of this chapter is supplement combinations and dosing strategies that are effective at promoting an acute physiological response that may improve/enhance exercise performance or influence chronic adaptations desired from training. In recent years, there has been a particular focus on two nutritional ergogenic aids—creatine monohydrate and protein/amino acids—in combination with specific nutrients in an effort to augment or add to their already established independent ergogenic effects. These combinations and others are discussed in this chapter.

    Objective To consolidate and assess information on counterfeit medicines subject to pharmaceutical alerts issued by the Peruvian Medicines Regulatory Authority over 18 years (1997–2014) of health monitoring and enforcement. Design A retrospective review of drug alerts. Setting A search of the website of the General Directorate of Medicines, Supplies and Drugs (DIGEMID) of the Ministry of Health of Peru for drug alerts issued between 1997 and 2014. Eligibility criteria Drug alerts related to counterfeit medicines. Results A total of 669 DIGEMID alerts were issued during the study period, 354 (52.91%) of which cover 1738 cases of counterfeit medicines (many alerts deal with several cases at a time). 1010 cases (58.11%) involved pharmaceutical establishments and 349 (20.08%) involved non-pharmaceutical commercial outlets. In 126 cases (7.25%), counterfeit medicines were seized in an unauthorised trade (without any marketing authorisation); in 253 cases (14.56%) the type of establishment or business associated with the seized product was not identified. Conclusions Counterfeit medicines are a serious public health problem in Peru. A review of the data cannot determine whether counterfeit medicines in Peru increased during the study period, or if monitoring by different government health agencies highlighted the magnitude of the problem by providing more evidence. The problem is clearly structural, since the majority of cases (58.11% of the total) were detected in legitimate supply chains. Most counterfeit medicines involve staple pharmaceutical products and common dosage forms. Considerable work remains to be done to control the serious problem of counterfeit medicines in Peru.

    Objectives Gastric carcinoma is the most common cancer and cause of cancer mortality in Peru. Helicobacter pylori, a bacterium that colonizes the human stomach, is a Group 1 carcinogen due to its causal relationship to gastric carcinoma. While eradication of H. pylori can help prevent gastric cancer, characterizing regional antibiotic resistance patterns is necessary to determine targeted treatment for each region. Thus, we examined primary antibiotic resistance in clinical isolates of H. pylori in Lima, Peru. Materials and methods H. pylori strains were isolated from gastric biopsies of patients with histologically proven H. pylori infection. Primary antibiotic resistance among isolates was examined using E-test strips. Isolates were examined for the presence of the cagA pathogenicity island and the vacA m1/m2 alleles via polymerase chain reaction. Results Seventy-six isolates were recovered from gastric biopsies. Clinical isolates showed evidence of antibiotic resistance to 1 (27.6%, n=21/76), 2 (28.9%, n=22/76), or ≥3 antibiotics (40.8%). Of 76 isolates, eight (10.5%) were resistant to amoxicillin and clarithromycin, which are part of the standard triple therapy for H. pylori infection. No trends were seen between the presence of cagA, vacA m1, or vacA m2 and antibiotic resistance. Conclusion The rate of antibiotic resistance among H. pylori isolates in Lima, Peru, is higher than expected and presents cause for concern. To develop more targeted eradication therapies for H. pylori in Peru, more research is needed to better characterize antibiotic resistance among a larger number of clinical isolates prospectively.

  16. Preterm nutrition and the brain.

    Ramel, Sara E; Georgieff, Michael K

    2014-01-01

    The brain is the most highly metabolic organ in the preterm neonate and consumes the greatest amount of nutrient resources for its function and growth. As preterm infants survive at greater rates, neurodevelopment has become the primary morbidity outcome of interest. While many factors influence neurodevelopmental outcomes in preterm infants, nutrition is of particular importance because the healthcare team has a great deal of control over its provision. Studies over the past 30 years have emphasized the negative neurodevelopmental consequences of poor nutrition and growth in the preterm infant. While all nutrients are important for brain development, certain ones including glucose, protein, fats (including long-chain polyunsaturated fatty acids), iron, zinc, copper, iodine, folate and choline have particularly large roles in the preterm infant. They affect major brain processes such as neurogenesis, neuronal differentiation, myelination and synaptogenesis, all of which are proceeding at a rapid pace between 22 and 42 weeks' post-conception. At the macronutrient level, weight gain, linear growth (independent of weight gain) and head circumference growth are markers of nutritional status. Each has been associated with long-term neurodevelopment. The relationship of micronutrients to neurodevelopment in preterm infants is understudied in spite of the large effect these nutrients have in other young populations. Nutrients do not function alone to stimulate brain development, but rather in concert with growth factors, which in turn are dependent on adequate nutrient status (e.g. protein, zinc) as well as on physiologic status. Non-nutritional factors such as infection, corticosteroids, and inflammation alter how nutrients are accreted and distributed, and also suppress growth factor synthesis. Thus, nutritional strategies to optimize brain growth and development include assessment of status at birth, aggressive provision of nutrients that are critical in this time

    The consequences of global warming on the Peru-Chile Current System (PCCS) ocean circulation are examined with a high-resolution, eddy-resolving regional oceanic model. We performed a dynamical downscaling of climate scenarios from the IPSL-CM4 Coupled General Circulation Model (CGCM), corresponding to various levels of CO2 concentrations in the atmosphere. High-resolution atmospheric forcing for the regional ocean model are obtained from the IPSL atmospheric model run on a stretched grid with increased horizontal resolution in the PCCS region. When comparing future scenarios to preindustrial (PI) conditions, the circulation along the Peru and Chile coasts is strongly modified by changes in surface winds and increased stratification caused by the regional warming. While the coastal poleward undercurrent is intensified, the surface equatorial coastal jet shoals and the nearshore mesoscale activity are reinforced. Reduction in alongshore wind stress and nearshore wind stress curl drive a year-round reduction in upwelling intensity off Peru. Modifications in geostrophic circulation mitigate this upwelling decrease in late austral summer. The depth of the upwelling source waters becomes shallower in warmer conditions, which may have a major impact on the system's biological productivity.

    Soil dwelling Uropodina mites were collected from a primary lowland rainforest in Amazonian Peru. The species found belong to three different families. A new diagnosis and the type genus of Tetrasejaspidae fam. nov. are given, and the family is recorded from Peru for the first time on the basis of Tetrasejaspis sellnicki Hirschmann, 1973. Two rotundabaloghid mites were collected (Rotundabaloghia (Circobaloghia) magna Hirschmann, 1992 and Rotundabaloghia (Circobaloghia) iquitosensis Hirschmann, 1992), both already reported from Peru. A new species (Origmatrachys peruensis sp. nov.) from the family Trachyuropodidae was collected in large numbers from soil, and is described on the basis of females, males, nymphs and larvae. This is the first description of the protonymphs and larvae of Origmatrachys. The new species differs from the previously described ones in the basis of sculptural pattern of dorsal, ventral, sternal shields and the length of the setae in the central part of the dorsal shield. A new key to the known adults and deutonymphs of Origmatrachys is given.

    Congenital hypothyroidism (CH) is the most important cause of preventable mental retardation. The prevalence of CH varies by geographic region, race and ethnicity. In the countries of the Northern hemisphere, the prevalence has been reported as 1:4,000 live newborns. The prevalence is remarkably different among the countries of Latin America not only because of their different races and ethnicities but also because of the heterogeneous social-economic development. The prevalence of CH in 1984 in Peru was reported as 1:1250. In 2007, the reported incidence by the Instituto Nacional Materno Perinatal was 1:1638. A recent retrospective study performed by the Instituto Nacional de Salud del Niño in Lima, Peru described the average age of diagnosis of CH as 5,9 months +/- 5,28. This late age of CH diagnosis certainly suggests the poor efficiency of the current neonatal CH screening programs in Peru. Every Peruvian infant deserves a timely newborn screening and treatment for CH. The Peruvian government is responsible for ensuring this mandatory goal is achieved promptly.

    The purpose of this review is to show the experimental studies carried out on the biological cycle, culture, pathogenicity of the anisakidae nematode larvae and to disseminate the information regarding current epidemy and the probable emergence of anisakidosis in Peru, and in addition, to propose measures of prevention and control, as well as the perspective and need for investigation. The studies of experimental pathogenicity in cats, dos, and hamsters are incomplete. Eight cases of acute human anisakidosis have been reported (5 confirmed and 3 unconfirmed). It is probable that it emerges during the "El Niño" Weather Phenomenon; however, during normal conditions it is probably due to the increase of raw fish consumption and other factors. In the coast of Peru, five and four fishes of direct human consumption are parasited by the Anisakis simplex and Anisakis physeteris larva, respectively, and two fishes are parasited by the Pseudoterranova decipiens. The main host for the Anisakis simplex is the dolphin (Delphinus delphia), but the Contracaecum osculatum is hosted by the sea lion: Otaria byronia and Arctocephalus australis, P. decipiens parasita a O. byronia. Eviscerating the fish would be most adequate prevention method to lessen the risk of human infection. There is evidence that anisakidosis is an underestimated zoonosis in Peru, and that it is probably and emerging disease. Therefore, its presence is to be suspected in patients with the prototype clinical syndrome.

    Given the need to reduce socio- economic and environmental drought in Peru as well as the vulnerability and increasing responsiveness and recovery to these events, the National Service of Meteorology and Hydrology of Peru (SENAMHI ) in conjunction with the Peru's Environment Ministry has developed a plan Drought Monitoring nationwide, which consists of two components: 1) Monitoring System and 2 ) Dissemination System . The first component consists of calculating drought indicators at national level; and for that purpose we have selected the following indexes: Normal Precipitation Index (NPI), Standardized Precipitation Index (SPI) , Precipitation Concentration Index (PCI) , Vegetation Condition Index (VCI ) , Temperature Condition Index ( TCI) , Healthy Vegetation Index (VHI ) and Streamflow Drought Index (SDI). In order to estimate these index observed climatological and hydrological data of SENAMHI network is used as well as remote sensing data of precipitation, temperature and vegetation (TRMM, CHIRPS and MODIS). The second component is the spread of these indicators and a compilation thereof to a summary document that integrates all indicators (Monthly Bulletin). This will be done through newsletters and a website (www.senamhi.gob.pe/serviciosclimaticos); in the case of exceptional drought events special notes will be made. A date has launched the first newsletter in September 2014. This drought monitoring system will be used as an instrument of climate service and we intend to make it a useful tool for decision makers and the general population .

  4. Nutritional sustainability of pet foods.

    PubMed

    2013-03-01

    Sustainable practices meet the needs of the present without compromising the ability of future generations to meet their needs. Applying these concepts to food and feed production, nutritional sustainability is the ability of a food system to provide sufficient energy and essential nutrients required to maintain good health in a population without compromising the ability of future generations to meet their nutritional needs. Ecological, social, and economic aspects must be balanced to support the sustainability of the overall food system. The nutritional sustainability of a food system can be influenced by several factors, including the ingredient selection, nutrient composition, digestibility, and consumption rates of a diet. Carbon and water footprints vary greatly among plant- and animal-based ingredients, production strategy, and geographical location. Because the pet food industry is based largely on by-products and is tightly interlinked with livestock production and the human food system, however, it is quite unique with regard to sustainability. Often based on consumer demand rather than nutritional requirements, many commercial pet foods are formulated to provide nutrients in excess of current minimum recommendations, use ingredients that compete directly with the human food system, or are overconsumed by pets, resulting in food wastage and obesity. Pet food professionals have the opportunity to address these challenges and influence the sustainability of pet ownership through product design, manufacturing processes, public education, and policy change. A coordinated effort across the industry that includes ingredient buyers, formulators, and nutritionists may result in a more sustainable pet food system.

  19. Food for nutrition: mainstreaming nutrition in WFP.

    PubMed

    2006-03-01

    Most preventable deaths among hungry people take place outside of emergency contexts. In countries not involved in conflicts or natural disasters malnutrition is directly implicated in the deaths of millions of children and mothers each year. Thus, WFP's great efforts focused on saving lives in emergencies should be mirrored by efforts aimed at tackling malnutrition, and hence saving lives, beyond emergencies as well. While food sufficiency is not the same as good nutrition, food is nevertheless an important part of the nutrition equation. New scientific evidence confirms that it is possible to have positive nutritional impacts with food aid. Consistent with Strategic Priority No. 3, WFP seeks to use food resources to achieve nutritional impacts in three complementary ways: a) enhancing the effectiveness and impact of targeted mother and child health and nutrition interventions (MCHN) that combine food and appropriate nonfood inputs; b) enhancing the nutritional value of WFP food (for instance, through micronutrient fortification); and c) enhancing the nutritional impact of other WFP (non-MCHN) interventions. These approaches represent a mainstreaming of nutrition across WFP's activities. Adoption of evidence-based programming, joint interventions with partners, and new project designs offer the promise of greater WFP effectiveness and impact in the coming years.

    Background Vector-borne transmission of Trypanosoma cruzi is seen exclusively in the Americas where an estimated 8 million people are infected with the parasite. Significant research in southern Peru has been conducted to understand T. cruzi infection and vector control, however, much less is known about the burden of infection and epidemiology in northern Peru. Methodology A cross-sectional study was conducted to estimate the seroprevalence of T. cruzi infection in humans (n=611) and domestic animals [dogs (n=106) and guinea pigs (n=206)] in communities of Cutervo Province, Peru. Sampling and diagnostic strategies differed according to species. An entomological household study (n=208) was conducted to identify the triatomine burden and species composition, as well as the prevalence of T. cruzi in vectors. Electrocardiograms (EKG) were performed on a subset of participants (n=90 T. cruzi infected participants and 170 age and sex-matched controls). The seroprevalence of T. cruzi among humans, dogs, and guinea pigs was 14.9% (95% CI: 12.2 – 18.0%), 19.8% (95% CI: 12.7- 28.7%) and 3.3% (95% CI: 1.4 – 6.9%) respectively. In one community, the prevalence of T. cruzi infection was 17.2% (95% CI: 9.6 - 24.7%) among participants < 15 years, suggesting recent transmission. Increasing age, positive triatomines in a participant's house, and ownership of a T. cruzi positive guinea pig were independent correlates of T. cruzi infection. Only one species of triatomine was found, Panstrongylus lignarius, formerly P. herreri. Approximately forty percent (39.9%, 95% CI: 33.2 - 46.9%) of surveyed households were infested with this vector and 14.9% (95% CI: 10.4 - 20.5%) had at least one triatomine positive for T. cruzi. The cardiac abnormality of right bundle branch block was rare, but only identified in seropositive individuals. Conclusions Our research documents a substantial prevalence of T. cruzi infection in Cutervo and highlights a need for greater attention and vector

    Saprotrophy on plant biomass is a recently developed nutrition strategy for Trichoderma. However, the physiology and evolution of this new nutrition strategy is still elusive. We report the deep sequencing and analysis of the genome of Trichoderma longibrachiatum, an efficient cellulase producer. The 31.7-Mb genome, smallest among the sequenced Trichoderma species, encodes fewer nutrition-related genes than saprotrophic T. reesei (Tr), including glycoside hydrolases and nonribosomal peptide synthetase-polyketide synthase. Homology and phylogenetic analyses suggest that a large number of nutrition-related genes, including GH18 chitinases, β-1,3/1,6-glucanases, cellulolytic enzymes, and hemicellulolytic enzymes, were lost in the common ancestor of T. longibrachiatum (Tl) and Tr. dN/dS (ω) calculation indicates that all the nutrition-related genes analyzed are under purifying selection. Cellulolytic enzymes, the key enzymes for saprotrophy on plant biomass, are under stronger purifying selection pressure in Tl and Tr than in mycoparasitic species, suggesting that development of the nutrition strategy of saprotrophy on plant biomass has increased the selection pressure. In addition, aspartic proteases, serine proteases, and metalloproteases are subject to stronger purifying selection pressure in Tl and Tr, suggesting that these enzymes may also play important roles in the nutrition. This study provides insights into the physiology and evolution of the nutrition strategy of Trichoderma.

    PubMed Central

    Puntis, J W L

    2006-01-01

    The theory and practice of nutritional support in the premature newborn has assumed increasing importance with survival of greater numbers of very immature infants. After birth, many do not tolerate full enteral feeding until gastrointestinal motor function has matured. During this process some will develop necrotising enterocolitis (NEC), a devastating failure of adaptation to postnatal life that may result in death, or severe complications. The feeding strategy that minimises the risk of NEC remains to be defined. In addition, promoting growth rates and nutrient accretion equivalent to those achieved during fetal development while optimising neurodevelopmental and long term health outcomes represents an important challenge for neonatologists. This review will focus on the problems associated with enteral nutrition, the requirement for parenteral nutrition, and the long term consequences of early nutritional interventions, underlining the need for prolonged follow up in assessing the potential benefits of different approaches to feeding.

    2014-07-22

    Nutritional abnormalities are associated with chronic obstructive pulmonary disease with a frequency ranging from 2 to 50%, depending on the geographical area and the study design. Diagnostic tools include anthropometry, bioelectrical impedance, dual energy radioabsortiometry and deuterium dilution, being the body mass and the lean mass indices the most frequently used parameters. While the most important consequences of nutritional abnormalities are muscle dysfunction and exercise limitation, factors implicated include an imbalance between caloric intake and consumption, and between anabolic and catabolic hormones, inflammation, tobacco smoking, poor physical activity, hypoxemia, some drugs and aging/comorbidities. The most important molecular mechanism for malnutrition associated with chronic obstructive pulmonary disease appears to be the mismatching between protein synthesis and breakdown. Among the therapeutic measures proposed for these nutritional abnormalities are improvements in lifestyle and nutritional support, although the use of anabolic drugs (such as secretagogues of the growth hormone) offers a new therapeutic strategy.

The Center of Excellence in Cervical Cancer Training is an interventional pioneer that has applied a methodological design intended to improve health professional skills and has disseminated this model to other Schools of Excellence. Through this intervention, the skills of 12,194 health professionals trained by the INEN have been strengthened with respect to nationwide promotion and primary and secondary prevention during the period of 2012-2015.

  18. Maternal nutrition in deprived populations.

    Shah, K P

    1981-02-01

    In deprived populations, a large proportion of women are chronically undernourished, the chances being therefore great that their infants will be undernourished in utero and present a low birth weight. Their children thus have a poor start in life, for which even breastmilk with its special protective and nutritive qualities cannot completely compensate, especially if the mothers continue to be chronically malnourished while subject to heavy workloads and repeated pregnancies. The supplementary feeding of pregnant and lactating women can to some extent offset these negative effects on both mother and child, but constitute a late intervention. Current literature on these issues is reviewed, and areas of action to improve women's nutritional status are indicated. In order to ensure that those most in need are reached at the grass roots level, the actions undertaken should be based on community participation, within the context of a multisectoral approach and a primary health care strategy.

    Background We aim to identify optimal strategies for deploying pre-exposure prophylaxis among men who have sex with men in the US and Peru to maximize population-level effectiveness in an efficient manner. We use epidemic models to simulate the impact of targeting strategies. Most studies have focused on targeting either the general population or high-risk MSM. Alternative strategies, including serodiscordant couples, may better balance effectiveness and efficiency. Methods We use dynamic, stochastic sexual network models based in exponential-family random graph modeling, parameterized from behavioral surveys of MSM in the US and Peru. These models represent main partnerships and casual contacts separately, permitting modeling of interventions targeting men whose risk derives from combinations of relational types. We also model varying rates of uptake and adherence to PrEP. We assess sensitivity of results to risk compensation via increases in condomless casual contacts and condomless sex in main partnerships. Results Targeting all men who are not exclusively insertive has the largest impact on HIV incidence, but targeting only those with high levels of casual activity yields comparable results using fewer person-years on PrEP. The effect is robust to risk compensation in the US, but less so in Peru. Targeting serodiscordant main partnerships does not significantly impact incidence, but requires fewer person-years on PrEP per infection averted than other strategies. Conclusions PrEP could be effective in reducing new infections at the population level in both settings. Serodiscordant partnerships are an attractive component of a targeting program, but targeting should include other high-risk men. PMID:25942463

    In Peru, the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW). Multiple studies correlate alcohol use disorders (AUDs) with risky sexual behaviors among Peruvian MSM. Qualitative research was used to inform a clinical trial on the acceptability of medication-assisted therapies to assist management of AUDs and improve antiretroviral therapy (ART) adherence among MSM/TGW in Peru. Three focus groups involving HIV-infected or HIV-uninfected MSM/TGW (n = 26) with AUDs (AUDIT ≥ 8) were transcribed, translated from Spanish into English, and analyzed using thematic content analysis. Despite having an AUD, participants considered themselves "social" drinkers, minimized their drinking behaviors, and differed about whether or not alcohol problems could be treated. Participants expressed skepticism about medication for treating AUDs. Three concepts emerged as necessary components of a treatment program for alcohol problems: cost, family support, and the potential to drink less alcohol without attaining total abstinence. This study reveals important areas of education to increase potential acceptability of a medication for treating AUDs among MSM/TGW. Given the social conditions and knowledge base of the participants, medication-assisted therapies using naltrexone may be a beneficial strategy for MSM with AUDs.

    Echinococcus granulosus, the etiologic agent of cystic echinococcosis (CE) in humans and other animal species, is distributed worldwide. Ten intra-specific variants, or genotypes (G1-G10), have been defined based on genetic diversity. To determine the genotypes present in endemic areas of Peru, samples were collected from cattle (44), sheep (41) and humans (14) from Junín, Puno Huancavelica, Cusco, Arequipa and Ayacucho. DNA was extracted from protoscolex and/or germinal layers derived from 99 E. granulosus isolates and used as templates to amplify the mitochondrial cytochrome C oxidase subunit 1 gene. The resulting polymerase chain reaction products were sequenced and further examined by sequence analysis. All isolates, independent of the host, exhibited the G1 genotype. Phylogenetic analysis showed that three isolates from Ayacucho shared the same cluster with microvariant G1(4). The G1 genotype is considered the most widespread and infectious form of E. granulosus worldwide and our results confirm that the same patterns apply to this country. Therefore, these findings should be taken into consideration in developing prevention strategies and control programs for CE in Peru.

  3. Recent advances in primate nutritional ecology.

    Righini, Nicoletta

    2017-04-01

    Nutritional ecology seeks to explain, in an ecological and evolutionary context, how individuals choose, acquire, and process food to satisfy their nutritional requirements. Historically, studies of primate feeding ecology have focused on characterizing diets in terms of the botanical composition of the plants consumed. Further, dietary studies have demonstrated how patch and food choice in relation to time spent foraging and feeding are influenced by the spatial and temporal distribution of resources and by social factors such as feeding competition, dominance, or partner preferences. From a nutritional perspective, several theories including energy and protein-to-fiber maximization, nutrient mixing, and toxin avoidance, have been proposed to explain the food choices of non-human primates. However, more recently, analytical frameworks such as nutritional geometry have been incorporated into primatology to explore, using a multivariate approach, the synergistic effects of multiple nutrients, secondary metabolites, and energy requirements on primate food choice. Dietary strategies associated with nutrient balancing highlight the tradeoffs that primates face in bypassing or selecting particular feeding sites and food items. In this Special Issue, the authors bring together a set of studies focusing on the nutritional ecology of a diverse set of primate taxa characterized by marked differences in dietary emphasis. The authors present, compare, and discuss the diversity of strategies used by primates in diet selection, and how species differences in ecology, physiology, anatomy, and phylogeny can affect patterns of nutrient choice and nutrient balancing. The use of a nutritionally explicit analytical framework is fundamental to identify the nutritional requirements of different individuals of a given species, and through its application, direct conservation efforts can be applied to regenerate and protect specific foods and food patches that offer the opportunity of a

    Balamuthia mandrillaris is an opportunistic free-living amoeba that has been reported to cause skin lesions and the fatal Balamuthia amoebic encephalitis (BAE) in humans and other animals. Currently, around 200 human BAE cases have been reported worldwide, although this number is considered to be underestimated. The highest number of BAE cases has been reported in the American continent, mainly in the southwest of the USA. Peru seems to be another hotspot for BAE with around 55 human cases having been identified, usually involving cutaneous infection, especially lesions in the central face area. The isolation of Balamuthia from environmental sources has been reported on only three prior occasions, twice from Californian soils and once from dust in Iran and so it seems that this amoeba is relatively rarely encountered in samples from the environment. We investigated that possibility of finding the amoebae in soil samples from different regions where clinical cases have been reported in Peru. Twenty-one samples were cultured in non-nutrient agar plates and were checked for the presence of B. mandrillaris-like trophozoites and/or cysts. Those samples that were positive for these amoebae by microscopic criteria were then confirmed by PCR amplification and DNA sequencing of the mitochondrial 16S rDNA gene of B. mandrillaris. We have detected the presence of B. mandrillaris in four samples collected in the regions of Piura (3) and Lima (1) where infection cases have been previously reported. We hypothesize that B. mandrillaris is present in Peru in soil and dust which therefore constitutes a source of the infection for the BAE cases previously reported in this country. Further studies should be carried out in the area to confirm the generality of this finding.

    Data from the national Peru Fertility Survey are used to estimate infant and childhood mortality ratios, 1968--77, for 124 Peruvian communities, ranging from small Indian hamlets in the Andes to larger cities on the Pacific coast. Significant mortality variations are found: mortality is inversely related to community population size and is higher in the mountains than in the jungle or coast. Multivariate analysis is then used to assess the influence of community population size, average female education, medical facilities, and altitude on community mortality. Finally, this study concludes that large-scale sample surveys, which include maternal birth history, add useful data for epidemiological studies of childhood mortality. PMID:6886581

    While studying respiratory infections of unknown etiology we detected Saffold virus in an oropharyngeal swab collected from a two-year-old female suffering from diarrhea and respiratory illness. The full viral genome recovered by deep sequencing showed 98% identity to a previously described Saffold strain isolated in Japan. Phylogenetic analysis confirmed the Peruvian Saffold strain belongs to genotype 3 and is most closely related to strains that have circulated in Asia. This is the first documented case report of Saffold virus in Peru and the only complete genomic characterization of a Saffold-3 isolate from the Americas.

    Early detection of prostate cancer in Peru is very uncommon, as patients usually arrive when the disease is locally advanced or advanced. There are no prostate cancer screening campaigns that allow us to detect this disease in early stages. The incidence rates, according to the Registry of Cancer in Metropolitan Lima, are increasing. However, there is probably an under register of cases in our country, since there are not any nation-wide records showing the real magnitude of this disease. It is imperative to develop prevention programs for the early diagnosis of prostate cancer through digital rectal exams and to perform the measurement of the prostate- specific antigen (PSA) in the blood.

    1995-08-01

    We studied preservation/dissolution cycles and paleoproductivity in eight sediment cores from the Peru Basin south of the highly productive surface waters of the eastern equatorial Pacific. Stratigraphy is based on stable oxygen isotopes and on combined magnetostratigraphy and biostratigraphy. Sediment cores which span the last 8 m.y., were retrieved during cruise 79 with RV SONNE close to the carbonate compensation depth (CCD). In general, sediments show Pacific-type carbonate cycles. We interpret a pronounced carbonate peak between 6 and 7 Ma as the result of a western and northern extension of the highly productive Peru Current. Decreased carbonate contents from the late Miocene to the late Pliocene might be associated with a slow contraction of the latitudinal extent of the high-productivity belt north of the study areas. During the Pliocene, carbonate variations showed 400 kyr cycles indicating the growth and decay of ice sheets, which should have been associated with pulsations of the Antarctic ice cap. An abrupt collapse of the carbonate system occurred at 2.4 Ma. Higher frequency variations of the carbonate record indicate the major increase of the northern hemisphere glaciation. During the Quaternary, carbonate fluxes are high during glacials and low during interglacials. Large amplitude variations with long broad minima and maxima, associated with small migrations of the lysocline and the CCD (< 200 m), are indicative of the preservation/dissolution history in the Peru Basin. During the early Pleistocene, climatic forcing by the 41 kyr obliquity cycle is not observed in the carbonate record. During the last 800 kyr, variability in the carbonate record was dominated by the 100 kyr eccentricity cycle. Fluxes of biogenic material (calcium carbonate, organic carbon, opal, and barium) were greatest during glacials, which imply higher productivity and export production of the Peru Current during cold climatic periods. Dissolution was greatest during

    Background Malnutrition is prevalent among peri-operative patients undergoing hepatobiliary surgery and is an important prognostic factor. Both hepatobiliary disease and surgical trauma significantly affects body’s metabolism and environment. Therefore, it is very important for patients with liver diseases undergoing hepatobiliary surgery to receive essential nutritional support during peri-operative period. Methods We summarized our clinical experience and reviewed of related literature to find the way for implementing the appropriate nutritional strategy. Results We found after comprehensively evaluating nutrition status, function of liver and gastrointestinal tract, nutritional strategy would be selected correctly. In severe malnutrition, initiation of enteral nutrition (EN) and/or parenteral nutrition (PN) with essential or special formulae is often recommended. Especially nasojejunal feeding is indicated that early application can improve nutritional status and liver function, reduce complications and prolong survival. Conclusions The reasonable peri-operative nutritional support therapy can improve the effect of surgical treatment and promote the patients’ recovery. PMID:26605277

    The diets of Americans fall far short of recommended dietary guidelines, and those who live in low-income households have even poorer diets than higher-income households. Many low-income Americans rely on the Supplemental Nutrition Assistance Program (SNAP). The program's dual goals are to improve food security and nutrition. Among the possible strategies to address dietary shortfalls among low-income Americans is to increase the SNAP benefit. This article uses data from the random assignment evaluation of the Summer Electronic Benefit Transfer for Children demonstration to add new insights on the impact of SNAP on diet quality for households receiving SNAP who also received SNAP-like benefits through Summer Electronic Benefit Transfer for Children. Households received $60 each month per eligible school-aged child. The objective of the evaluation was to see if Summer Electronic Benefit Transfer for Children improved children's food security and nutrition. The evaluation surveyed these households to collect information about food expenditures, food security, and children's diets. For households receiving SNAP in sites that used the SNAP Electronic Benefit Transfer delivery system, the analysis showed increases in food expenditures and decreases in levels of food insecurity. The analysis also indicates improvements in dietary quality among school-aged children, but the impacts were modest.

    On April 11 2010, the city of Carhuaz and settlements in the Chucchún Catchment (Ancash region, Peru) suffered the impact of a glacier lake outburst flood. An avalanche of rock and ice from the Mount Hualcán hit the glacier lake 513, triggering a glacial lake outburst flood (GLOF) of 1 million m3 which destroyed farmland and several infrastructures. Although there was no loss of human life, the event caused panic in the population. In consequence, the Municipality of Carhuaz prioritized GLOF-related risk management. The Glacier Project, funded by Swiss Agency for Development and Cooperation, and executed by CARE Peru and the University of Zurich, fosters the coordination among public institutions (Glaciological Unit of the National Water Authority, the Ministry of Environment and Municipality) and the population for risk management. In this contribution we present all components of the risk management strategy as well as the lessons learned during the implementation. Risk management involves managing both glacier hazard as well as the vulnerability of the population. In this framework a glaciological and geomorphological characterization of Mount Hualcán and lake 513 was perfomed in order to model past and potential future outburst floods and to assess the slope stability conditions. Based on three potential GLOF scenarios of different magnitudes, a hazard map was produced for the entire catchment, which served as the basis for the vulnerability and risk assessment as well as for the design and the implementation of an Early Warning System (EWS), including evacuation planning. The EWS consists of 4 components: 1) knowledge of risk, through hazard and vulnerability characterization; 2) monitoring and alert, through the installation of monitoring stations on lake 513 for detecting avalanches with geophones and cameras; 3) broadcasting and communications, through the implementation of communication protocols between the Municipality of Carhuaz and emergency

    Symptomatic high-altitude pulmonary hypertension and structural cardiac abnormalities related to high altitude have been reported previously. However, their true prevalence has not been systematically determined. We assessed clinical indicators of cardiovascular health or disease and correlated them with anatomic and physiologic cardiovascular features in preschool and schoolchildren living at 4000 m. We also estimated the prevalence of cardiovascular problems in the population, with emphasis on symptomatic high altitude pulmonary hypertension and structural cardiopathies. Three hundred and twenty-six children residents of Tintaya, Peru, were cross-sectionally studied. Methods included structured interviews, anthropometry and physical examination, arterial oxygen saturation, hemoglobin determination, electrocardiography, and echocardiography. The prevalence of structural cardiac problems was 1.5%, with less than 1% possibly attributable to high altitude. All children with structural cardiac abnormalities were identified by a focused physical exam prior to echocardiography. None were identified by the health interview. No symptomatic high altitude pulmonary hypertension was identified in the absence of underlying structural anomalies. The prevalence of structural cardiac problems was consistent with data from sea level. Active monitoring of the health status of a pediatric population at high altitude is valuable in the timely detection of cardiac abnormalities. Although our study children enjoyed generally excellent health, comparative, longitudinal studies are warranted to determine the incidence of high altitude cardiopulmonary problems and to identify risk factors and early markers for later disorders associated to life at high altitude. Our findings are applicable to children with some degree of high altitude genetic background and high mobility patterns to lower altitudes and living in comparatively good nutritional and socioeconomic conditions.

    Forty-five percent of the 6.6 million under-5 deaths in 2012 were attributable to infectious disease, of which pneumonia and diarrhea were the leading causes. Despite the close interrelation between these infections and nutrition conditions, key nutrition interventions for prevention of childhood diarrhea and pneumonia have not received deserved attention, especially in low- and middle-income countries. Several interventions and strategies can effectively address these issues but are not available to those in need. This article discusses in detail the burden and trends of global under-5 mortality, infections, and nutrition conditions; etiology and associated risk factors; biological plausibility and the interrelation between infections, nutrition, and growth; and existing interventions and strategies to reduce major childhood infections and improve nutrition and growth and implications.

  3. Enteral nutrition for optimal growth in preterm infants

    PubMed Central

    2016-01-01

    Early, aggressive nutrition is an important contributing factor of long-term neurodevelopmental outcomes. To ensure optimal growth in premature infants, adequate protein intake and optimal protein/energy ratio should be emphasized rather than the overall energy intake. Minimal enteral nutrition should be initiated as soon as possible in the first days of life, and feeding advancement should be individualized according to the clinical course of the infant. During hospitalization, enteral nutrition with preterm formula and fortified human milk represent the best feeding practices for facilitating growth. After discharge, the enteral nutrition strategy should be individualized according to the infant's weight at discharge. Infants with suboptimal weight for their postconceptional age at discharge should receive supplementation with human milk fortifiers or nutrient-enriched feeding, and the enteral nutrition strategy should be reviewed and modified continuously to achieve the target growth parameters.

    PubMed

    Hoffmann, Ingrid

    2003-09-01

    The reductionist approach has traditionally been and continues today as the dominant approach in nutrition research. This means that parts of diet rather than the whole, or single food components rather than food habits, are studied. Even though much progress has been made with this approach, the relationship between diet and health is not yet fully understood. With the recognition about the whole being more than the sum of its parts, the limitations on the applicability of the reductionist approach, and the growing knowledge about parts of diet, another epistemological approach, such as holism, and new research strategies, such as transdisciplinarity, are needed to reveal more about the relationship between diet and health.

    2017-02-01

    We propose a local magnitude scale (M L ) for Peru, based on the original Richter definition, using 210 seismic events between 2011 and 2014, recorded by 35 broadband stations of the National Seismic Network operated by the Geophysical Institute of Peru. In the solution model, we considered 1057 traces of maximum amplitude records on the vertical channel from simulated Wood-Anderson seismograms of shallow events (depths between 0 and 60 km) and hypocentral distances less than 600 km. The attenuation factor has been evaluated in terms of geometrical spreading and anelastic attenuation coefficients. The magnitude M L was defined as M L = L o g 10 A W A +1.5855L o g 10(R/100)+0.0008(R-100)+3±S, where, A W A is the displacement amplitude in millimeters (Wood-Anderson), R is the hypocentral distance (km), and S is the station correction. The results obtained for M L have good correlation with the m b , M s and M w values reported the ISC and NEIC. The anelastic attenuation curve obtained has a similar behavior to that other highly seismic regions. Station corrections were determined for all stations during the regression analysis resulting in values ranging between -0.97 and +0.73, suggesting a strong influence of local site effects on amplitude.

    Previously published estimates of the area of the Peru upwelling ecosystem vary by more than an order of magnitude. In an effort to improve this situation, we used a 24-month sequence of SeaWiFS satellite images of chlorophyll in the surface water off Peru from 5°S to 18.5°S during September 1997-August 1999 to estimate the size of the nutrient enhanced productive habitat associated with the upwelling. The first 12-month period was marked by El Niño conditions, the second by strong upwelling. Using a chlorophyll threshold of >1.0 mg m -3 to define the limit of the productive habitat resulted in maximum area estimates of 120×10 3 km 2 during September 1997-August 1998, and 220×10 3 km 2 during September 1998-August 1999. The latter result is consistent with an area estimate we calculated using total fishery landings and a regression relating fishery yields per unit area to annual primary production per unit area. Although year-to-year variation in the annual mean size of the upwelling ecosystem must be significant, even discounting El Niño events, our analysis has shown that at least five of the extreme earlier values are not good estimates of the size of the productive habitat. We may now be close to knowing the average size of the ecosystem to within a factor of about two.

    Oceanography and climate along the coast of Peru is fundamentally linked to ENSO variability with stronger lithic flux into the sea and reduced marine bioproductivity during El Nino events. A 19 m long piston core with laminated marine sediments has been recovered on the edge of the Peruvian shelf (12 03'S, 77 40W, 184 m waterdepth) during cruise Sonne-147 in 2000. We present the lower 6 meters of this core that cover the time between 100 to 130 kyr before the present (BP). SST has been estimated from alkenone analysis with a mean temporal resolution of 300 years. Color logging along the core at 2 mm intervals revealed high resolution proxy data (3 to 30 a) for the precipitation on the continent (fine-grained lithics) and marine bioproduction (photosynthesis pigments: chlorines, carotenoids). Proxy data show that a major change occurred around 123 kyr BP. Mean sedimentation rate which is largely controlled by lithics dropped from 40-70 cm/kyr to 18 cm/kyr after 123 kyr BP. Contemporaneously SST start to decline towards the early Glacial level that is reached between 118 to 116 ka during the time of glacial inception. We conclude that stronger El Nino floods occurred before 123 kyr BP and El Ninos were weaker during the second half of MIS 5e. The change to weaker ENSO activity in Peru is therewith roughly contemporaneous with the beginning cooling in Greenland.

    The causative agent of fasciolosis in South America is thought to be Fasciola hepatica. In this study, Fasciola flukes from Peru were analyzed to investigate their genetic structure and phylogenetic relationships with those from other countries. Fasciola flukes were collected from the three definitive host species: cattle, sheep, and pigs. They were identified as F. hepatica because mature sperms were observed in their seminal vesicles, and also they displayed Fh type, which has an identical fragment pattern to F. hepatica in the nuclear internal transcribed spacer 1. Eight haplotypes were obtained from the mitochondrial NADH dehydrogenase subunit 1 (nad1) sequences of Peruvian F. hepatica; however, no special difference in genetic structure was observed between the three host species. Its extremely low genetic diversity suggests that the Peruvian population was introduced from other regions. Nad1 haplotypes identical to those of Peruvian F. hepatica were detected in China, Uruguay, Italy, Iran, and Australia. Our results indicate that F. hepatica rapidly expanded its range due to human migration. Future studies are required to elucidate dispersal route of F. hepatica from Europe, its probable origin, to other areas, including Peru.

    The Cosmos Coronagraphic Observatory was completely destroyed by terrorists in 1988. In 1995, in coordination with the Minister of Education of Peru, a project to construct a new Educational Astronomical Observatory has been executed. The main purpose of the observatory is to promote an interest in basic space sciences in young students from school to university levels, through basic astronomical studies and observations. The planned observatory will be able to lodge 25 visitors; furthermore an auditorium, a library and a computer room will be constructed to improve the interest of people in astronomy. Two 15-cm refractor telescopes, equipped with a CCD camera and a photometer, will be available for observations. Also a 6-m dome will house a 60-cm class reflector telescope, which will be donated soon, thanks to a fund collected and organized by the Nishi-Harima Astronomical Observatory in Japan. In addition a new modern planetarium donated by the Government of Japan will be installed in Lima, the capital of Peru. These installations will be widely open to serve the requirements of people interested in science.

    While human illness associated with hantavirus infection has been documented in many countries of South America, evidence for hantavirus transmission in Peru has been limited to the isolation of Rio Mamore virus from a pigmy mouse rat (Oligoryzomys microtis) in the Amazon city of Iquitos. To address the possibility of human hantavirus exposure in the region, we screened febrile patients reporting to health clinics in Iquitos from 2007 to 2010 for serological evidence of recent hantavirus infection. In addition, we conducted a serological survey for hantavirus-reactive IgG among healthy participants residing in Iquitos and rural areas surrounding the city. Through the febrile surveillance study, we identified 15 participants (0.3%; 15/5174) with IgM reactive to hantavirus (Andes virus) antigen, all with relatively mild, self-limited illness. From the cross-sectional serosurvey we found that 1.7% (36/2063) of residents of the Iquitos area had serum IgG reactive to one or more hantaviruses, with a higher prevalence in the urban population (2.2%, compared to 1.1% in rural areas). These results suggest that human infection with hantavirus has occurred in Peru.

    Between May and October 2002, a cluster of acute febrile illnesses occurred in the subtropical Andean foothills of Peru. Serologic evidence in villages where disease had been documented showed that the prevalence of IgM antibody to Leptospira ranged from 6% to 52%, that of IgM antibody to spotted fever group (SFG) rickettsia ranged from 10% to 19%, and that of IgM antibody to Coxiella burnetii from 1% to 15%. Measurement of IgG antibodies for SFG rickettsiae suggested that this disease was endemic. In contrast, IgG antibodies against C. burnetii were largely absent. In humans, microagglutination tests identified pathogenic variants of Leptospira. The presence of an SFG rickettsial infection was confirmed in four febrile patients following polymerase chain reaction and sequencing of the conserved 17-kD common antigen gene (htrA). Collectively, these analyses indicated that Rickettsia sp., C. burnetii, and Leptospira sp. were circulating in the region during the time of disease outbreak and implicate the involvement of an as yet undetermined SFG rickettsia in northwestern Peru.

    Liver levels of arsenic, cadmium, copper, lead, manganese, and zinc were assessed in adult female sheep living in the vicinity of a zinc smelter in Peru. The study was conducted on a large sheep-raising cooperative divided into seven management units, operated under a standardized husbandry system. Soil samples were analyzed for the same metals at varying distances from the smelter. A gradient of concentration of heavy metals in soil was found between 1 and 56 km from the smelter. Soil concentrations for all metals except manganese decreased significantly with increasing distance from the smelter. The strongest correlations were found for copper, lead, and zinc (P less than 0.001). Topographic features and prevailing wind direction appeared to play a role in the dispersion of pollutants. Liver samples were obtained from 153 sheep on five units of the cooperative. The centers of the units sampled were between 13 and 56 km from the smelter. Hepatic concentrations of arsenic, lead, manganese, and zinc decreased significantly with increasing distance from the smelter. Liver arsenic and liver zinc were significantly related to soil concentrations. Liver levels of arsenic, cadmium, lead, and manganese in sheep from the cooperative were significantly higher than those detected in control sheep from southern Peru. Sheep populations may serve as biological monitors for heavy metal accumulation and environmental carcinogenesis.

    We present the preliminary results of a provenance study of obsidians samples from Cerrillos (ca. 800 100 b.c.) using Mössbauer Spectroscopy. The Cerrillos archaeological site, located in the Upper Ica Valley, Peru, is the only Paracas ceremonial center excavated so far. The archaeological data collected suggest the existence of a complex social and economic organization on the south coast of Peru. Provenance research of obsidian provides valuable information about the selection of lithic resources by our ancestors and eventually about the existence of communication routes and exchange networks. We characterized 18 obsidian artifacts samples by Mössbauer spectroscopy from Cerrillos. The spectra, recorded at room temperature using different velocities, are mainly composed of broad asymmetric doublets due to the superposition of at least two quadrupole doublets corresponding to Fe2+ in two different sites (species A and B), one weak Fe3+ doublet (specie C) and magnetic components associated to the presence of small particles of magnetite. Multivariate statistical analysis of the Mössbauer data (hyperfine parameters) allows to defined two main groups of obsidians, reflecting different geographical origins.

  14. Constrained Choices: Adolescents Speak on Sexuality in Peru

    While numerous studies have explored adolescent sexual behavior in Peru, to date, none have explored how adolescents situate sexuality within the context of their broader lives. This information is needed to inform policies and programs. Life history interviews were conducted with 20 12–17 year-old females and males from a low-income settlement near Lima, Peru. Data were analyzed using holistic content analysis and grounded theory. Sexuality had a strong presence in adolescents’ lives. However, adolescents viewed the complete expression of their sexuality as a constrained choice. Constraints are due to the belief that sexual intercourse always results in pregnancy; the nature of sex education; the provision of proscriptive advice; and the family tensions, economic problems, racism and violence present in adolescents’ lives. Social and cultural factors seem to surpass and often suppress the physical and psychological dimensions of adolescents’ sexuality. The results of this study can inform policies and programs to support adolescents as they construct their sexuality and make sexuality-related decisions. PMID:20526920

  15. Nutrition in the adolescent.

    Wahl, R

    1999-02-01

    This article reviews the nutritional requirements of puberty and the clinical assessment of nutritional status, and discusses the nutritional risks imposed by vegetarian diets, pregnancy, and athletic involvement. Energy (calories) and protein are essential in pubertal development. Adolescent females require approximately 2200 calories/day, whereas male adolescents require 2500-3000 calories/day. Additional intake requirements include fat, calcium, iron, zinc, vitamins, and fiber. The clinical assessment of nutritional status begins with obtaining a good diet history of the patient and this could be offered by the body mass index. Nutritional deficiencies and poor eating habits established during adolescence can have long-term consequences, including delayed sexual maturation, loss of final adult height, osteoporosis, hyperlipidemia, and obesity. As for vegetarian adolescents, nutritional risks include lack of iodine, vitamin B12, vitamin D, and some essential fatty acids. In addition, substances in some grains reduce gut absorption, thus increasing mineral deficiencies. Pregnancy may also be a risk factor for poor nutrition during adolescence. A pregnant adolescent has different nutritional needs because she is still growing. Among adolescent athletes many are turning to nutritional supplements in an attempt to improve athletic performance. A balanced, varied diet provides adequate calories and nutrition to meet the needs of most adolescents. They also have greater water needs than do adult athletes. Details on adolescent health concerns are further discussed in this article.

    Nutritional status affects every pediatric patient's response to illness. Good nutrition is important for achieving normal growth and development. Nutritional assessment therefore should be an integral part of the care for every pediatric patient. Routine screening measures for abnormalities of growth should be performed on all pediatric patients. Those patients with chronic illness and those at risk for malnutrition should have detailed nutritional assessments done. Components of a complete nutritional assessment include a medical history, nutritional history including dietary intake, physical examination, anthropometrics (weight, length or stature, head circumference, midarm circumference, and triceps skinfold thickness), pubertal staging, skeletal maturity staging, and biochemical tests of nutritional status. Alternative measures for linear growth assessment (e.g., lower leg and upper arm measures) can be performed on patients unable to stand or who have musculoskeletal deformities. Bone densitometry can be used to assess bone mineralization and the risk of fracture. Nutritionally at risk patients may benefit from determination of resting energy expenditure by indirect calorimetry. The use of age, gender, and disease-specific growth charts is essential in assessing nutritional status and monitoring nutrition interventions. The importance of accurate measurements using trained personnel and appropriate equipment cannot be overemphasized.

    Unhealthy nutrition is a leading factor in various rehabilitation diagnoses such as stroke and several musculoskeletal complications. Further, the association between nutrition, pain management, and brain plasticity support the importance of having rehabilitation patients follow healthy nutrition guidelines. The goal of this brief report is to emphasize the importance of nutritional counseling to physiatrists and to briefly describe recommended communication skills, behavioral change strategies, and opportunities for interprofessional collaborations. Potential next steps aimed at prescribing nutrition within physiatry clinics are provided. Incorporating healthy nutrition in the physiatrist's personal and professional life presents an opportunity for a meaningful change. Physiatrists can lead the way one bite at a time. The time for a healthy approach to food is now.

  19. Nutrition considerations for open-water swimming.

    2014-08-01

    Open-water swimming (OWS) is a rapidly developing discipline. Events of 5-25 km are featured at FINA World Championships, and the international circuit includes races of 5-88 km. The Olympic OWS event, introduced in 2008, is contested over 10 km. Differing venues present changing environmental conditions, including water and ambient temperatures, humidity, solar radiation, and unpredictable tides. Furthermore, the duration of most OWS events (1-6 hr) creates unique physiological challenges to thermoregulation, hydration status, and muscle fuel stores. Current nutrition recommendations for open-water training and competition are either an extension of recommendations from pool swimming or are extrapolated from other athletic populations with similar physiological requirements. Competition nutrition should focus on optimizing prerace hydration and glycogen stores. Although swimmers should rely on self-supplied fuel and fluid sources for shorter events, for races of 10 km or greater, fluid and fuel replacement can occur from feeding pontoons when tactically appropriate. Over the longer races, feeding pontoons should be used to achieve desirable targets of up to 90 g/ hr of carbohydrates from multitransportable sources. Exposure to variable water and ambient temperatures will play a significant role in determining race nutrition strategies. For example, in extreme environments, thermoregulation may be assisted by manipulating the temperature of the ingested fluids. Swimmers are encouraged to work with nutrition experts to develop effective and efficient strategies that enhance performance through appropriate in-competition nutrition.

    On an international scale, the last seventy-five years have been a period of deep social, economic and political transformation for the developing countries. They have been especially influenced by the international phenomenon of globalization, the benefits of which have been unequally distributed among countries. In this context, the strategies used to improve the general nutritional health of the population of developing countries include broad approaches integrating nutritional interventions in a context of sustainable community development, while valuing the existing relations between fields as diverse as agriculture, education, sociology, economy, health, environment, hygiene and nutrition. The community nutrition programmes are emblematic of these initiatives. Nevertheless, in spite of the increasing evidence of the potential possibilities offered by these programmes to improve the nutritional status and contribute to the development and the self-sufficiency of the community, their success is relatively limited, due to the inappropriate planning, implementation and evaluation of the programmes. In the present article, I attempt to emphasie the importance of community participation of the population of developing countries in the community nutrition programmes within the context of globalization. This process is not only an ethical imperative, but a pragmatic one. It is a crucial step in the process of liberation, democratization and equality that will lead to true sustainable development.

Here we complement the previously published checklist with the addition of 83 nominal species and six genera, including three genera recorded only from morphospecies. This increases the list of ants reported from Peru to at least 679 species and subspecies and 85 genera. We also modify the list of species known as endemic from Peru, discuss the historical importance of the Peruvian ant fauna in myrmecology, and highlight potential research for future studies.

These maps and data compilation show evidence for activity of Quaternary faults and folds in Peru and its offshore regions of the Pacific Ocean. The maps show the locations, ages, and activity rates of major earthquake-related features such as faults and fault-related folds. These data are accompanied by text databases that describe these features and document current information on their activity in the Quaternary.

    Because the contortion in the seismic zone in southern Peru is aligned approximately parallel to the direction of relative plate motion, rather than perpendicular to the coast of Peru, the position of the contortion need not migrate with respect to the overriding South American plate as the Nazca plate subducts beneath it, and the flow in the surrounding asthenosphere could be in a steady state. In addition, the position of the contortion defines the northern boundary of the volcanic arc in southern Peru. The inference that a wedge of asthenospheric material must overlie the downgoing slab for subduction-related volcanism to occur is thereby strengthened.

    Undernutrition is the single largest contributor to the global burden of disease and can be addressed through a number of highly efficacious interventions. Undernutrition generally has not received commensurate attention in policy agendas at global and national levels, however, and implementing these efficacious interventions at a national scale has proven difficult. This paper reports on the findings from studies in Bangladesh, Bolivia, Guatemala, Peru and Vietnam which sought to identify the challenges in the policy process and ways to overcome them, notably with respect to commitment, agenda setting, policy formulation and implementation. Data were collected through participant observation, documents and interviews. Data collection, analysis and synthesis were guided by published conceptual frameworks for understanding malnutrition, commitment, agenda setting and implementation capacities. The experiences in these countries provide several insights for future efforts: (a) high-level political attention to nutrition can be generated in a number of ways, but the generation of political commitment and system commitment requires sustained efforts from policy entrepreneurs and champions; (b) mid-level actors from ministries and external partners had great difficulty translating political windows of opportunity for nutrition into concrete operational plans, due to capacity constraints, differing professional views of undernutrition and disagreements over interventions, ownership, roles and responsibilities; and (c) the pace and quality of implementation was severely constrained in most cases by weaknesses in human and organizational capacities from national to frontline levels. These findings deepen our understanding of the factors that can influence commitment, agenda setting, policy formulation and implementation. They also confirm and extend upon the growing recognition that the heavy investment to identify efficacious nutrition interventions is unlikely to reduce

    Cervical cancer is the leading malignant neoplasm in Peruvian women. This malignancy is a public health problem and several efforts were previously performed to develop cancer control plans. Geographical, cultural, structural, infrastructural and procedural barriers can limit the implementation of such strategies. Several previous studies have characterized human papilloma virus (HPV) epidemiology, where prevalence of high-risk HPV in adult females is ~12% and the prevalence in cervical cancer is 90–95%. The predominant barriers for the control of cervical cancer are lack of specialists in remote villages, education/cultural issues, loss of patients in follow-up, lack of access to HPV testing and lack of compliance for HPV vaccination. A good strategy for the prevention and early detection of high-risk HPV, pre-malignant neoplasms and cervical cancer, identified by interventional studies, is the self-sampling test, which assists with overcoming the cultural and geographic barriers. The current cancer control plan, termed ‘Plan Esperanza’, is performed with massive training of health professionals and social sensitization campaigns leading to filling the gaps regarding education and, in addition, it provides cancer care coverage for poorer individuals. In our experience at Oncosalud-AUNA, with a cohort of ~750,000 affiliates using a pre-paid system with annual screenings for cervical cancer for women, offered free-of-charge, a lower incidence of this malignancy (5.8/100,000) is now observed compared with the national incidence (32.7/100,000). As in other countries, the HPV vaccination can be a cost-utility strategy to reduce the high burdens of cervical cancer in Peru, a rapid and cheap HPV molecular sub-typification is rapidly required.

    2008-08-01

    Sexual and romantic relationships between local people and tourists have long taken place. Such encounters are not a modern phenomenon, but the potential of sexually transmitted infections (STIs), including HIV/AIDS, warrants greater research into the issue. This paper analyses local people's views of local-tourist relationships in Cuzco/Peru. Data were obtained through in-depth interviews, participant and non-participant observation and informal discussions. Attraction based on physical difference was reportedly the main trigger for such relationships. Emerging themes discussed include issues of self-esteem, strategies of approach, tourists' motives, emotional involvement and expectations from such encounters. Levels of unprotected sexual behaviour and lack of STI awareness are of sufficient concern to recommend urgent action. Suggestions for sexual health education are made with particular emphasis on targeting local people involved in the tourism and hospitality industries.

    Ten years has passed since we began the nutrition support team(NST)to make a regional alliance between local institutions for construction of the NST network. The network was formed with the following aims: 1) regional joint conferences for learning about nutrition with family doctors, facilities, and hospitals; 2) open general meetings for information about nutrition within the suburbs of our city; 3) preparing and sending an NST manual about parenteral nutrition(PN)and enteral nutrition(EN); and 4) preparation of an NST summary of patient malnutrition to foster mutual understanding. We produced a questionnaire summarizing the completion of nutritional management in patients. The following positive benefits were observed: 1) improved nutritional motivation and technique; 2) reduced nutritional confusion after discharge from our hospital; and 3) lower levels of anxiety in the facilities, the patient, and among the patient's family. In addition, follow-upinquiries allowed us to estimate whether our nutritional strategy was adequate. A more widely open regional alliance is needed in the future to strengthen patient nutrition following hospital discharge.

    Plagiarism is a serious, yet widespread type of research misconduct, and is often neglected in developing countries. Despite its far-reaching implications, plagiarism is poorly acknowledged and discussed in the academic setting, and insufficient evidence exists in Latin America and developing countries to inform the development of preventive strategies. In this context, we present a longitudinal case study of seven instances of plagiarism and cheating arising in four consecutive classes (2011-2014) of an Epidemiology Masters program in Lima, Peru, and describes the implementation and outcomes of a multifaceted, "zero-tolerance" policy aimed at introducing research integrity. Two cases involved cheating in graded assignments, and five cases correspond to plagiarism in the thesis protocol. Cases revealed poor awareness of high tolerance to plagiarism, poor academic performance, and widespread writing deficiencies, compensated with patchwriting and copy-pasting. Depending on the events' severity, penalties included course failure (6/7) and separation from the program (3/7). Students at fault did not engage in further plagiarism. Between 2011 and 2013, the Masters program sequentially introduced a preventive policy consisting of: (i) intensified research integrity and scientific writing education, (ii) a stepwise, cumulative writing process; (iii) honor codes; (iv) active search for plagiarism in all academic products; and (v) a "zero-tolerance" policy in response to documented cases. No cases were detected in 2014. In conclusion, plagiarism seems to be widespread in resource-limited settings and a greater response with educational and zero-tolerance components is needed to prevent it.

    Endemic dengue transmission has been documented in the Amazonian city of Iquitos, Peru, since the early 1990s. To better understand the epidemiology of dengue transmission in Iquitos, we established multiple active surveillance systems to detect symptomatic infections. Here we compare the efficacy of distinct community-based (door to door) and school absenteeism-based febrile surveillance strategies in detecting active cases of dengue. Febrile episodes were detected by both systems with equal rapidity after disease onset. However, during the period that both programs were running simultaneously in 2004, a higher number of febrile cases in general (4.52/100 versus 1.64/100 person-years) and dengue cases specifically (2.35/100 versus 1.29/100 person-years) were detected in school-aged children through the community-based surveillance program. Similar results were obtained by direct comparison of 435 participants concurrently enrolled in both programs (P < 0.005). We conclude that, in Iquitos, community-based door-to-door surveillance is a more efficient and sensitive design for detecting active dengue cases than programs based on school absenteeism.

    Interpolity interaction and regional control were central features of all early state societies, taking the form of trade-embedded in political processes to varying degrees-or interregional conquest strategies meant to expand the polity's control or influence over neighboring territories. Cross-cultural analyses of early statecraft suggest that territorial expansion was an integral part of the process of primary state formation, closely associated with the delegation of authority to subordinate administrators and the construction of core outposts of the state in foreign territories. We report here on a potential case of a core outpost, associated with the early Virú state, at the site of Huaca Prieta in the Chicama Valley, located 75 km north of the Virú state heartland on the north coast of Peru. This site is discussed in the context of other possible Virú outposts in the Moche Valley, Pampa La Cruz, and Huaca Las Estrellas, and as part of a broader reflection on expansionary dynamics and statecraft.

    Summary Disability is the result of interactions between biological and environmental factors including the physical, economic, and social barriers imposed on an individual by society. In low and middle-income countries, limited attention has been given to the situation of individuals with intellectual disabilities, who remain seriously neglected. Given the lack of resources available to address mental disorders, it is essential to examine the role of socioeconomic and socio-cultural factors in the lives of these individuals. We conducted interviews of key informants and community members in a shantytown community in Lima, Peru, to explore public knowledge, perceptions, and attitudes regarding intellectual disability. Findings indicated that the most important concern for community members was the longstanding issues associated with poverty. There was a profound lack of awareness of intellectual disability among the general population and an absence of social integration for these individuals. However, interviewees also recognized the productive potential of persons with intellectual disabilities provided they received currently inaccessible support services. The results suggest that educational efforts and intervention strategies must be mindful of the challenges of chronic poverty in order to successfully facilitate the social integration of individuals with intellectual disabilities into the community.

    Inadequate dietary intake is the primary nutritional concern of today's female athlete. As these athletes fail to consume enough energy to support the physical demands of training, they become at risk for disordered eating, amenorrhea, and osteoporosis, conditions collectively identified as the female athlete triad. This review addresses nutritional concerns of the female athlete, identification of those at risk, relationship of energy intake to menstrual irregularities, and recently identified chronic diseases associated with the female athlete triad. Strategies are offered to prevent harmful behaviors leading to the comorbidities associated with inadequate dietary intakes.

    Rivers, although inherently dynamic, have been chosen as political boundaries since the beginning of colonization for several reasons. Such divisions were chosen namely for their defensive capabilities and military benefits, and because they were often the first features mapped out by explorers. Furthermore, rivers were indisputable boundaries that did not require boundary pillars or people to guard them. However, it is important to understand the complexities of a river as a boundary. All rivers inevitably change over time through processes such as accretion, deposition, cut-off, or avulsion, rendering a political boundary subject to dispute. Depending upon the flow, size, and surrounding land, a river will migrate differently than others. As these natural features migrate one country loses land while another gains land leading to tension between legal rigidity and fluid dynamism. This in turn can manifest in social disruption due to cultural differences, political upheaval, or conflict risk as a result of scarce water resources. The purpose of this research is to assess the temporal and spatial variability of the political boundaries of Peru that follow rivers. Peru shares borders with Colombia, Brazil, Bolivia, Chile, and Ecuador. A large part of its northern border with Colombia follows the Putumayo River and later the Amazon River. Part of its eastern border with Brazil follows the Yavari River and later the Yaquirana River. These rivers are natural features used as political boundaries yet they differ in how each migrates. By means of a spatial and temporal analysis of satellite images it was possible to obtain erosion and deposition areas for the Putumayo River, the portion of the Amazon River that is part of the Peruvian boundary, the Yavari River, and the Yaquirana River. The erosion and deposition areas were related to land distribution among Peru, Colombia, and Brazil. By examining the Digital Elevation Model one can see how the altitude of the

  5. Aqueducts and geoglyphs : the response of Ancient Nasca to water shortages in the desert of Atacama (Peru)

    Masini, Nicola; Lasaponara, Rosa

    2016-04-01

    The desert of Atacama is a plateau in South America, covering a 1,000-kilometre strip of land on the Pacific coast, west of the Andes mountains, between Chile and Peru. Due to the confluence of a cold ocean current (the Humboldt Current) along with other climatic factors, connected to the particular topography and geomorphology of the region, Atacama desert is one of the most arid areas of the world. In particular, in Nasca region (Southern Peru) the lack of water was (and still is) due to the following causes: (i) the scarce pluvial precipitations and the (ii) high infiltration capacity, and the consequent yearly significant reduction of the surface water (Schreiber & Lancho Rojas 2009). Over the millennia long periods of drought occurred and frequently the lack of water was persistent for several decades. Despite the arid and extreme nature of the environment, this region was populated by important civilizations, such as Paracas and Nasca, which flourished in the Early Intermediate period (200 BCE-500 AD) (Silvermann & Proulx 2002). In particular the Nasca civilization is well-known for its refined and colourful pottery, characterized by a rich icononographic repertory, and, above all, by the huge and mysterious geoglyphs drawn on the arid plateaus of the Rio Grande de Nasca Basin. In order to practice agriculture, the Nasca developed adequate strategies to cope with hostile environmental factors and water scarcity, building a very efficient aqueduct system. They were aided by the fact that underground water was likely enough close to the surface and accessible by constructing wells and underground aqueducts, known with quechua name of puquios (Schreiber & Lancho Rojas 2009; Lasaponara & Masini 2012a; 2012b) The effectiveness of the techniques of hydraulic engineering depended on the climate and the weather events that sometimes underwent drastic changes, as results of the cyclical phenomenon of El Niño Southern Oscillation (commonly called ENSO).

    In Peru, the industry's development has made economic improvements but at the same time, it has had a major impact on the health of the workers; for that reason, it was necessary to generate control mechanisms. So, in 1940 it was created the Departmento de Higiene Industrial, which in 1956 was changed to Instituto de Salud Ocupacional, but it was deactivated in 1994. However, in 2001 it reappeared into the Ministerio de Salud organizational structure with the name of Instituto de Salud Ocupacional "Alberto Hurtado Abadía". Actually, it is the Centro Nacional de Salud Ocupacional y Protección del Ambiente para la Salud (CENSOPAS), organ of the Instituto Nacional de Salud which continues working in synergy with other institutions and sectors, making research to protect the health of exposed persons (workers and community) to contamination and risks associated with economic activities.

    Within and between tombs at the 1,000-year-old site of Huaca Loro on north coastal Peru, interment characteristics vary to an intriguing degree. Following and elaborating upon prior intracemetery studies, biological relatedness among associated burial groupings was assessed using 23 dental characters (assuming familial allele segregation) for 29 individuals. Biological patterning was based on multivariate distance between individuals using all traits, rather than the previously widespread reliance upon univariate comparison of each trait separately within samples. This multivariate approach did seem more informative. Statistically significant variation of biological similarities and dissimilarities corresponded to spatial groupings and also to various specific archaeological indications of the cohesiveness, or lack thereof, of interment pattern. The partition of biological distances among tombs at Huaca Loro supports the archaeological evidence that the tombs represent a planned elite cemetery.

    The tourniquet test (TT) is a physical examination maneuver often performed on patients suspected of having dengue. It has been incorporated into dengue diagnostic guidelines and is used in clinical studies. However, little is known about TT performance characteristics in different patient types or epidemiologic conditions. In the dengue-endemic city of Iquitos, Peru, we performed TTs and dengue laboratory assays on 13,548 persons with febrile disease, recruited through either active (n = 1,095) or passive (n = 12,453) surveillance. The sensitivity was 52% and 56%, the specificity was 58% and 68%, the positive predictive value was 45% and 55%, and the negative predictive value was 64% and 69% for persons enrolled in active and passive surveillance, respectively. We demonstrated that the TT was more sensitive identifying dengue disease in women and those of younger age and that sensitivity increased the later a person came to a medical clinic for care.

    During the past decade, incidence of human infection with rabies virus (RABV) spread by the common vampire bat (Desmodus rotundus) increased considerably in South America, especially in remote areas of the Amazon rainforest, where these bats commonly feed on humans. To better understand the epizootiology of rabies associated with vampire bats, we used complete sequences of the nucleoprotein gene to infer phylogenetic relationships among 157 RABV isolates collected from humans, domestic animals, and wildlife, including bats, in Peru during 2002–2007. This analysis revealed distinct geographic structuring that indicates that RABVs spread gradually and involve different vampire bat subpopulations with different transmission cycles. Three putative new RABV lineages were found in 3 non–vampire bat species that may represent new virus reservoirs. Detection of novel RABV variants and accurate identification of reservoir hosts are critically important for the prevention and control of potential virus transmission, especially to humans.

    The Peruvian Andes are the home of 27 species of frogs of the genus Telmatobius, many of which are critically endangered. Illegal trade of adult frogs for purported medical properties likely represents the major threat facing these species. This activity, besides reducing their populations, may contribute to the dissemination of the fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, a disease posing a threat to many populations of amphibians. We screened frogs confiscated by the Administration of Forestry and Wildlife in Lima, Peru, for Bd. We used real-time PCR to diagnose Bd at the Laboratory of Wildlife, Faculty of Veterinary Medicine and Zootecnics, Universidad Peruana Cayetano Heredia, in Lima and Pisces Molecular Laboratory in Boulder, Colorado, US. Of 62 samples collected during this study, 60% (37) were PCR positive for Bd, confirming that illegal trade of amphibians can pose a risk for disseminating Bd.

    Archaeological research has identified the use of cultivated cotton (Gossypium barbadense) in the ancient Andes dating back to at least 7800 years ago. Because of unusual circumstances of preservation, 6000-year-old cotton fabrics from the Preceramic site of Huaca Prieta on the north coast of Peru retained traces of a blue pigment that was analyzed and positively identified as an indigoid dye (indigotin), making it the earliest known use of indigo in the world, derived most likely from Indigofera spp. native to South America. This predates by ~1500 years the earliest reported use of indigo in the Old World, from Fifth Dynasty Egypt [ca. 4400 BP (before present)]. Indigo is one of the most valued and most globally widespread dyes of antiquity and of the present era (it being the blue of blue jeans).

    1984-01-01

    Using data from the World Fertility Survey of 1977-78, this paper examines how community characteristics influence completed fertility in Peru. The analysis shows that community characteristics do not condition (interact with) the effects of mother's education in determining completed fertility. Rather, the effects of community characteristics are best described by a threshold model, which posits that below or above critical cut points, the effects on fertility of community (or individual) characteristics will diminish or increase. Empirical results showed that residence in communities with higher levels of access to the benefits of development decreased completed fertility beyond what one would have predicted on the basis of women's characteristics alone, and this effect was further amplified with increasing levels of development.

    Creutzfeldt-Jakob disease (CJD) is a fatal neurological disease caused by pathological isoform of the human prion protein. Clinical features of six cases of the sporadic form of CJD with definitive diagnosis by histopathology, and five cases with probable diagnosis were reported in patients treated at the Peruvian National Institute of Neurological Sciences. The average age of onset in definite cases was 55.8 years and in probable cases was 59.6, mostly males. The average disease duration was 8.8 months. A typical EEG was found in 50% of definite cases and in 80% of probable. The 14-3-3 protein in cerebrospinal fluid was positive in a probable case, and typical MRI findings were observed in two probable cases. All cases studied had a typical clinical course of the disease, and it is considered as the first report of CJD in Peru.

All five people received the same lot of 17DD live attenuated yellow fever vaccine before their illness; four of the five died of confirmed YEL-AVD. The surviving case was classified as probable YEL-AVD. Intensive investigation yielded no abnormalities of the implicated vaccine lot and no common risk factors. This is the first described space-time cluster of yellow fever viscerotropic disease involving more than two cases. Mass yellow fever vaccination should be avoided in areas that present extremely low risk of yellow fever.

    This study explores the lives of Peruvian adolescents in a low-income human settlement outside of Lima. Twenty 12–17 year olds were asked to narrate their own life stories using the life history narrative research method. Holistic content analysis was coupled with a grounded theory approach to explore these data. Intergenerational responsibility, family tensions, economic pressures, racism and violence emerged without prompting and dominated the narrators’ life stories, underscoring the degree to which these adolescents lack access to the supportive individuals and structures that are key to positive adolescent development. The challenges faced by these and the other 5.8 million 10 to 19 year olds in Peru requires increased attention to the role of families, peers and communities in ensuring that adolescents are able to maintain their well-being and achieve their future expectations.

    In Arequipa, Peru, vectorborne transmission of Chagas disease by Triatoma infestans has become an urban problem. We conducted an entomologic survey in a periurban community of Arequipa to identify risk factors for triatomine infestation and determinants of vector population densities. Of 374 households surveyed, triatomines were collected from 194 (52%), and Trypanosoma cruzi–carrying triatomines were collected from 72 (19.3%). Guinea pig pens were more likely than other animal enclosures to be infested and harbored 2.38× as many triatomines. Stacked brick and adobe enclosures were more likely to have triatomines, while wire mesh enclosures were protected against infestation. In human dwellings, only fully stuccoed rooms were protected against infestation. Spatially, households with triatomines were scattered, while households with T. cruzi–infected triatomines were clustered. Keeping small animals in wire mesh cages could facilitate control of T. infestans in this densely populated urban environment. PMID:17073082

    Many gay men in the popular sectors of Lima, Peru participate in vóley callejero, or street volleyball. The ethnographic data presented in this article describes verbal and corporal mechanisms through which gay identity emerges within the particular context of the street volleyball game, ultimately highlighting the contextual nature of identity. The volleyball players are not just hitting a ball back and forth, they are engaging in a meaningful activity that illuminates intersections of language, sexuality, and identity. Through the manipulation of the street into a volleyball court, the volleyball players create a space conducive to the articulation of particular verbal and embodied practices that index gay identity. The challenge to the regulations of "proper" volleyball through the practice of ritual insulting and the cultivation of gay volleyball technique are playful reconfigurations of gendered practices prominent in the sites where fieldwork was carried out.

    Magda Mateus Cardenas, trained as an anthropologist, is currently director of Centro Amauta, a feminist organization in Peru that addresses issues of gender, class, and culture. In this interview, Mateus Cardenas describes her long involvement with development organizations and grass-roots campaigns to improve women's status. She notes that, although many organizations have adopted a gender perspective, few comprehend its highly political, transformational aspects. Women's rights tend to be viewed by development agencies as just one more factor to be incorporated into development projects rather than as a perspective that changes views of development itself. A genuine gender perspective entails changes in the organizational, social, and political aspects of the themes of autonomy and empowerment, with adaptations of content and methods to local conditions. A precondition to women's emancipation is access to and control of financial and economic resources. This, in turn, requires training in technical skills and access to the marketplace on more competitive terms.

To better understand the epizootiology of rabies associated with vampire bats, we used complete sequences of the nucleoprotein gene to infer phylogenetic relationships among 157 RABV isolates collected from humans, domestic animals, and wildlife, including bats, in Peru during 2002-2007. This analysis revealed distinct geographic structuring that indicates that RABVs spread gradually and involve different vampire bat subpopulations with different transmission cycles. Three putative new RABV lineages were found in 3 non-vampire bat species that may represent new virus reservoirs. Detection of novel RABV variants and accurate identification of reservoir hosts are critically important for the prevention and control of potential virus transmission, especially to humans.

    Bartonella infections were investigated in bats in the Amazon part of Peru. A total of 112 bats belonging to 19 species were surveyed. Bartonella bacteria were cultured from 24.1% of the bats (27/112). Infection rates ranged from 0% to 100% per bat species. Phylogenetic analyses of gltA of the Bartonella isolates revealed 21 genetic variants clustering into 13 divergent phylogroups. Some Bartonella strains were shared by bats of multiple species, and bats of some species were infected with multiple Bartonella strains, showing no evident specific Bartonella sp.-bat relationships. Rarely found in other bat species, the Bartonella strains of phylogroups I and III discovered from the common vampire bats (Desmodus rotundus) were more specific to the host bat species, suggesting some level of host specificity.

    The oldest old are among the fastest growing segment of the population and it is important to understand not only the influence of modifiable lifestyle factors such as diet and nutrition on the achievement of exceptional longevity but also the role, if any, of these factors on maintaining optimal cognitive, mental and physical health into advanced age. This review summarizes studies of dietary intake and patterns of long-lived peoples and presents current knowledge of nutritional status of centenarians as determined with nutritionally relevant biomarkers, providing information on comparative levels of the various biomarkers between centenarians and older adult controls and on the prevalence and predictors of nutritional deficiencies in centenarians. The studies indicate that BMI and nutritional status as indicated by circulating levels of antioxidant vitamins, vitamin B12, folate, homocysteine and 25(OH) vitamin D of centenarians are quite heterogeneous and influenced by region of residency and many of the demographic, dietary and lifestyle factors that influence nutritional status in other older adults. While many of the studies have been small, convenience samples of relatively healthy community-dwelling centenarians, a few have population-based or included participants of varying cognitive functioning. These and future studies examining associations between nutritional status and cognitive, mental and physical function should be instrumental in determining the role of nutrition in promoting longevity and improving the quality of life in these exceptional survivors.

    Objectives In developing nations, the use of operational parameters (OPs) in the prediction of clinical care represents a missed opportunity to enhance the care process. We modeled the impact of multiple measurements of antiretroviral treatment (ART) adherence on antiretroviral treatment outcomes in Peru. Design And Methods Retrospective cohort study including ART naïve, non-pregnant, adults initiating therapy at Hospital Nacional Cayetano Heredia, Lima-Peru (2006-2010). Three OPs were defined: 1) Medication possession ratio (MPR): days with antiretrovirals dispensed/days on first-line therapy; 2) Laboratory monitory constancy (LMC): proportion of 6 months intervals with ≥1 viral load or CD4 reported; 3) Clinic visit constancy (CVC): proportion of 6 months intervals with ≥1 clinic visit. Three multi-variable Cox proportional hazard (PH) models (one per OP) were fit for (1) time of first-line ART persistence and (2) time to second-line virologic failure. All models were adjusted for socio-demographic, clinical and laboratory variables. Results 856 patients were included in first-line persistence analyses, median age was 35.6 years [29.4-42.9] and most were male (624; 73%). In multivariable PH models, MPR (per 10% increase HR=0.66; 95%CI=0.61-0.71) and LMC (per 10% increase 0.83; 0.71-0.96) were associated with prolonged time on first-line therapies. Among 79 individuals included in time to second-line virologic failure analyses, MPR was the only OP independently associated with prolonged time to second-line virologic failure (per 10% increase 0.88; 0.77-0.99). Conclusions The capture and utilization of program level parameters such as MPR can provide valuable insight into patient-level treatment outcomes. PMID:24098475

    This is the first study of adobe brick contamination anywhere in the world. Huancavelica, Peru is the site of historic cinnabar refining and one of the most mercury (Hg) contaminated urban areas in the world. Over 80% of homes in Huancavelica are constructed with adobe bricks made from Hg contaminated soil. In this study we measured total Hg concentrations in adobe brick, dirt floor, surface dust, and air samples from the interior of 60 adobe brick houses located in four neighborhoods. Concentrations of total Hg in adobe bricks, dirt floors, and surface dust ranged from 8.00 to 1070 µg/g, 3.06 to 926 µg/g, and 0.02 to 9.69 µg/wipe, respectively, with statistically significant differences between the four neighborhoods. Concentrations of Hg in adobe brick and dirt floor samples in Huancavelica were orders of magnitude higher than in Ayacucho, a non-mining town in Peru. A strong correlation exists between total Hg concentrations in adobe bricks and dirt floors which confirms that adobe bricks were being made on-site and not purchased from an off-site source. A strong correlation between surface dust and adobe bricks and dirt floors indicates that walls and floors serve as indoor sources of Hg contamination. Elemental Hg vapor concentrations were below detection (<0.5 µg/m(3)) in most homes; however in homes with detectable levels, concentrations up to 5.1 µg/m(3) were observed. No statistically significant differences in Hg vapor measurements were observed between neighborhoods. This study demonstrates that building materials used widely in developing communities, such as adobe bricks, may be a substantial source of residential Hg exposure in silver or gold refining communities where Hg is produced or used for amalgamation in artisanal gold production.
