Challenges for implementing Earthquake Early Warning: A Case Study in Nicaragua

NASA Astrophysics Data System (ADS)

Massin, F.; Clinton, J. F.; Boese, M.; Cauzzi, C.; Strauch, W.

2017-12-01

Earthquake early warning (EEW) systems aim at providing fast and accurate estimates of event parameters or local ground shaking over wide ranges of source dimensions and epicentral distances. The Swiss Seismological Service (SED) has integrated EEW solutions into the SeisComP3 (SC3) professional earthquake monitoring software. VS(SC3) provides fast magnitude estimates for network-based point-sources using conventional triggering and phases association techniques, while FinDer(SC3) matches the evolving patterns of ground motion to track on-going rupture extent, and can provide accurate ground motion predictions for finite fault ruptures. SC3 is widely used, including in Central America, and at INETER in Nicaragua. In 2016, SED and INETER started a joint project to assess the feasibility of EEW in Nicaragua and Central America and to set up a prototype EEW system. We test VS(SC3) and FinDer(SC3) softwares at INETER since 2016. Excellent relations between regional seismic networks mean broadband and strong motion seismic data are exchanged across Central America in real time, which means the network is sufficient to warrant investigation into its potential for EEW. We report on the successes and challenges of operating an EEW system where seismicity is high, but infrastructure is fragile and the design and operation of a seismic network is challenging (in Nicaragua, on average 50% of all stations do not work effectively for EEW). The current best EEW delays for on-shore earthquakes in Nicaragua is in the order of 20s and 40s offshore. However, the current network should be able to provide EEW in 10 to 15s on-shore and 20 to 25s off-shore which correspond to potential EEW intensities over or equal to VII. We compare the performances of EEW in Nicaragua with an ideal setting, featuring optimized data availability. We evaluate improvements strategies of the Nicaraguan and the Joint Central American Seismic Networks for EEW. And we discuss how to combine real-time EEW

To assess private-sector stakeholders' and donors' perceptions of a total market approach (TMA) to family planning in Nicaragua in the context of decreased funding; to build evidence for potential strategies and mechanisms for TMA implementation (including public-private partnerships (PPPs)); and to identify information gaps and future priorities for related research and advocacy. A descriptive exploratory study was conducted in various locations in Nicaragua from March to April 2010. A total of 24 key private-sector stakeholders and donors were interviewed and their responses analyzed using two questionnaires and a stakeholder analysis tool (PolicyMakerTM software). All survey participants supported a TMA, and public-private collaboration, in family planning in Nicaragua. Based on the survey responses, opportunities for further developing PPPs for family planning include building on and expanding existing governmental frameworks, such as Nicaragua's current coordination mechanism for contraceptive security. Obstacles include the lack of ongoing government engagement with the commercial (for-profit) sector and confusion about regulations for its involvement in family planning. Strategies for strengthening existing PPPs include establishing a coordination mechanism specifically for the commercial sector and collecting and disseminating evidence supporting public-private collaboration in family planning. There was no formal or absolute opposition to a TMA or PPPs in family planning in Nicaragua among a group of diverse nongovernmental stakeholders and donors. This type of study can help identify strategies to mobilize existing and potential advocates in achieving articulated policy goals, including diversification of funding sources for family planning to achieve contraceptive security.

Women's strategic responses to violence in Nicaragua

2001-01-01

STUDY OBJECTIVE—To describe the responses of women in León, Nicaragua to partner abuse and identify contextual factors associated with the use of certain coping mechanisms and the likelihood of permanent separation.
DESIGN—Cross sectional population-based survey.
SETTING—León, Nicaragua.
PARTICIPANTS—188 women 15-49 years of age who had experienced physical partner abuse, out of 488 women interviewed.
MAIN RESULTS—66% of women defended themselves effectively from abuse either physically or verbally. Forty one per cent of women had left home temporarily because of violence and 20% had sought help outside the home. Women experiencing severe abuse were more likely to leave or seek help, whereas women with less severe abuse were more able to defend themselves effectively. Seventy per cent of women eventually left abusive relationships. Help seeking and temporary separations increased the likelihood of a permanent separation, whereas women who defended themselves and were able to stop the violence, at least temporarily, were more likely to remain in abusive relationships.
CONCLUSIONS—Women in Nicaragua use a variety of methods in order to overcome physical partner abuse. Temporary leaving and help seeking are critical steps in the process of leaving a violent relationship. However, many women indicated that they did not receive support for their situation. More interventions are needed to help women recognise and deal with violence, as well as strengthening the community support networks available to abused women.

1999-01-01

OBJECTIVES: This study measured the prevalence, frequency, and severity of physical wife abuse and its risk factors in León, Nicaragua. METHODS: A cross-sectional survey was conducted with a representative sample of 488 women 15 to 49 years of age. RESULTS: The lifetime prevalence of spousal violence was 52% among ever-married women (n = 360). Spousal violence was significantly positively associated with poverty, parity, urban residence, and history of violence in the husband's family. No significant associations were found between spousal violence and women's age, education, marital dependency, or occupation. CONCLUSIONS: Wife abuse constitutes a major public health problem in Nicaragua, requiring urgent measures for prevention and treatment for victims. PMID:9949757

Men's Educational Group Appointments in Rural Nicaragua.

PubMed

Campbell, Bruce B; Gonzalez, Hugo; Campbell, McKenzie; Campbell, Kent

2017-03-01

Men's preventive health and wellness is largely neglected in rural Nicaragua, where a machismo culture prevents men from seeking health care. To address this issue, a men's educational group appointment model was initiated at a rural health post to increase awareness about hypertension, and to train community health leaders to measure blood pressure. Men's hypertension workshops were conducted with patient knowledge pretesting, didactic teaching, and posttesting. Pretesting and posttesting performances were recorded, blood pressures were screened, and community leaders were trained to perform sphygmomanometry. An increase in hypertension-related knowledge was observed after every workshop and community health leaders demonstrated proficiency in sphygmomanometry. In addition, several at-risk patients were identified and follow-up care arranged. Men's educational group appointments, shown to be effective in the United States in increasing patient knowledge and satisfaction, appear to function similarly in a resource-constrained environment and may be an effective mechanism for reaching underserved men in Nicaragua.

Geo hazard studies and their policy implications in Nicaragua

Nicaragua, situated at the Central American Subduction zone and placed in the trajectory of tropical storms and hurricanes, is a frequent showplace of natural disasters which have multiplied the negative effects of a long term socioeconomic crisis leaving Nicaragua currently as the second poorest country of the Americas. In the last years, multiple efforts were undertaken to prevent or mitigate the affectation of the natural phenomena to the country. National and local authorities have become more involved in disaster prevention policy and international cooperation boosted funding for disaster prevention and mitigation measures in the country. The National Geosciences Institution (INETER) in cooperation with foreign partners developed a national monitoring and early warning system on geological and hydro-meteorological phenomena. Geological and risk mapping projects were conducted by INETER and international partners. Universities, NGO´s, International Technical Assistance, and foreign scientific groups cooperated to capacitate Nicaraguan geoscientists and to improve higher education on disaster prevention up to the master degree. Funded by a World Bank loan, coordinated by the National System for Disaster Prevention, Mitigation and Attention (SINAPRED) and scientifically supervised by INETER, multidisciplinary hazard and vulnerability studies were carried out between 2003 and 2005 with emphasis on seismic hazard. These GIS based works provided proposals for land use policies on a local level in 30 municipalities and seismic vulnerability and risk information for each single building in Managua, Capital of Nicaragua. Another large multidisciplinary project produced high resolution air photos, elaborated 1:50,000 vectorized topographic maps, and a digital elevation model for Western Nicaragua. These data, integrated in GIS, were used to assess: 1) Seismic Hazard for Metropolitan Managua; 2) Tsunami hazard for the Pacific coast; 3) Volcano hazard for Telica

Extracting Environmental Benefits from a New Canal in Nicaragua: Lessons from Panama

PubMed Central

Condit, Richard

2015-01-01

Biologists have raised objections to a new canal in Nicaragua, but in this Essay I argue that dire predictions of environmental catastrophe are exaggerated. I present an alternative view based on my research experience in Panama, where Canal operations foster forest conservation. Currently in Nicaragua, the rate of forest loss is so rapid that the canal cannot make it worse. Rather, I contend, adoption of international standards in canal construction could lead to net environmental and social benefits for the country. PMID:26214182

Occupational injuries identified by an emergency department based injury surveillance system in Nicaragua

2004-01-01

Objectives: To identify and describe the work related injuries in both the formal and informal work sectors captured in an emergency department based injury surveillance system in Managua, Nicaragua. Setting: Urban emergency department in Managua, Nicaragua serving 200–300 patients per day. Methods: Secondary analysis from the surveillance system data. All cases indicating an injury while working and seen for treatment at the emergency department between 1 August 2001 and 31 July 2002 were included. There was no exclusion based on place of occurrence (home, work, school), age, or gender. Results: There were 3801 work related injuries identified which accounted for 18.6% of the total 20 425 injures captured by the surveillance system. Twenty seven work related fatalities were recorded, compared with the 1998 International Labor Organization statistic of 25 occupational fatalities for all of Nicaragua. Injuries occurring outside of a formal work location accounted for more than 60% of the work related injuries. Almost half of these occurred at home, while 19% occurred on the street. The leading mechanisms for work related injuries were falls (30%), blunt objects (28%), and stabs/cuts (23%). Falls were by far the most severe mechanism in the study, causing 37% of the work related deaths and more than half of the fractures. Conclusions: Occupational injuries are grossly underreported in Nicaragua. This study demonstrated that an emergency department can be a data source for work related injuries in developing countries because it captures both the formal and informal workforce injuries. Fall prevention initiatives could significantly reduce the magnitude and severity of occupational injuries in Managua, Nicaragua. PMID:15314050

The burden of dengue in Nicaragua has been steadily rising during the last three decades; however, there have been few efforts to quantify the burden (measured in disability-adjusted life years [DALYs]) and cost to society. Using primary data from the Nicaraguan Ministry of Health (MINSA), the total cost and burden of dengue were calculated from 1996 to 2010. Total costs included both direct costs from medical expenditures and prevention activities and indirect costs from lost productivity. The annual disease burden ranged from 99 to 805 DALYs per million, with a majority associated with classic dengue fever. The total cost was estimated to be US$13.5 million/year (range: US$5.1–27.6 million). This analysis can help improve allocation of dengue control resources in Nicaragua and the region. As one of the most comprehensive analyses of its type to date in Nicaragua and Latin America, this study can serve as a model to determine the burden and cost of dengue. PMID:22890033

The Global Fund and tuberculosis in Nicaragua: building sustainable capacity?

Plamondon, Katrina M; Hanson, Lori; Labonté, Ronald; Abonyi, Sylvia

2008-01-01

The purpose of the study was to explore and provide feedback on local stakeholders' experiences with the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM) as it related to capacity building for tuberculosis (TB) services in Nicaragua. An ethnomethodological approach was used to capture the experiences of three different groups: service providers, service recipients, and decision-makers. Data collection involved reviewing secondary texts and records, participant observation, and in-depth interviews and focus groups in both rural and urban municipalities. Stakeholders felt that Nicaragua's Global Fund project improved TB control, built human resource capacity and strengthened community involvement in TB programming; however, they noted several contextual and structural threats to sustainable capacity development. The nature of the GFATM's performance-based evaluation de-emphasized qualitative assessment and, at times, created pressure to meet numeric targets at the risk of decreasing quality. Contextual challenges often determined or limited the potential sustainability of activities. Two examples (training volunteer health workers and establishing TB Clubs) from the broader study are offered here to highlight these challenges from health systems and community perspectives. Current approaches to GFATM evaluation and accountability may compromise its positive impacts on capacity building in Nicaragua. Greater consideration needs to be given to ensuring more comprehensive evaluation of project implementation.

Camino Verde (the Green Way) is an evidence-based community mobilisation tool for prevention of dengue and other mosquito-borne viral diseases. Its effectiveness was demonstrated in a cluster-randomised controlled trial conducted in 2010-2013 in Nicaragua and Mexico. The Nicaraguan arm of the trial was preceded, from 2004 to 2008, by a feasibility study that provided valuable lessons and trained facilitators for the trial itself. Here, guided by the Template for Intervention Description and Replication (TIDieR), we describe the Camino Verde intervention in Nicaragua, presenting its rationale, its time and location, activities, materials used, the main actors, modes of delivery, how it was tailored to encourage community engagement, modifications made from the feasibility study to the trial itself, and how fidelity to the process originally designed was maintained. We also present information on costs and discuss the place of this study within the literature on implementation science. ISRCTN27581154 .

2014-01-01

Background Epidemic severe leptospirosis was recognized in Nicaragua in 1995, but unrecognized epidemic and endemic disease remains unstudied. Methodology/Principal Findings To determine the burden of and risk factors associated with symptomatic leptospirosis in Nicaragua, we prospectively studied patients presenting with fever at a large teaching hospital. Epidemiologic and clinical features were systematically recorded, and paired sera tested by IgM-ELISA to identify patients with probable and possible acute leptospirosis. Microscopic Agglutination Test and PCR were used to confirm acute leptospirosis. Among 704 patients with paired sera tested by MAT, 44 had acute leptospirosis. Patients with acute leptospirosis were more likely to present during rainy months and to report rural residence and fresh water exposure. The sensitivity of clinical impression and acute-phase IgM detected by ELISA were poor. Conclusions/Significance Leptospirosis is a common (6.3%) but unrecognized cause of acute febrile illness in Nicaragua. Rapid point-of-care tests to support early diagnosis and treatment as well as tests to support population-based studies to delineate the epidemiology, incidence, and clinical spectrum of leptospirosis, both ideally pathogen-based, are needed.

Gender, inequality and Depo-Provera: Constraints on reproductive choice in Nicaragua.

PubMed

Yarris, Kristin Elizabeth; Dent, Nicolette Jeannette

2017-04-01

This article examines the sociocultural determinants of Nicaraguan women's use of Depo-Provera as a means of contraception. The prevalence of Depo-Provera in Nicaragua is high and increasing compared to other Central American countries. Drawing on data from structured interviews with 87 women and from focus groups with 32 women, we show how women's preference for Depo is shaped by both gendered inequalities and socioeconomic constraints. We employ basic statistical tests to analyse correlations between women's marital status and socioeconomic status (SES) with contraceptive use. Our statistical findings show significant associations between use of Depo and both marital status and SES, such that women who are married or in conjugal unions and women with lower SES are more likely to use Depo. To help explain women's use of Depo-Provera in Nicaragua, we situate our findings within the context of gender, culture, and power, reviewing the contested history of Depo-Provera in the developing world and dynamics of gender inequality, which constrain women's contraceptive choices. We conclude with suggestions for reproductive health programming in Nicaragua and beyond, arguing that gender equity and addressing socioeconomic barriers to family planning remain priorities for the achievement of global reproductive health.

International collaboration for pediatric oncology nursing leadership: Nicaragua and Canada.

2009-01-01

In 2005, with financial support from the Pediatric Oncology Group of Ontario, a pilot nursing leadership project linked pediatric oncology nurses from Canada with nurses at the La Mascota Hospital in Managua, Nicaragua. Following consultation with the pediatric oncology team in Nicaragua, a program was developed to strengthen clinical nursing leadership in a clinical setting through continuing education. The nurses believed that care of the patient and family improved due to the increased leadership skills of nurses in the unit and as the profile and credibility of nurses as peers in the health care team became evident. Providing nurses with the autonomy and financing for a project related directly to nursing care represented an important development for leadership in the profession.

Environmental pollution and shipping feasibility of the Nicaragua Canal.

PubMed

Chen, Jihong; Zeng, Xin; Deng, Yibing

2016-12-15

In recent years, the Nicaraguan government's renewed interest in constructing this interoceanic canal has once again aroused widespread concern, particularly in the global shipping industry. The project's immense ecological risks, coupled with the recent expansions of both the Panama Canal and the Suez Canal, have raised questions among scientists and experts about its viability. Whether the Nicaragua Canal is really feasible for international shipping, given its high marine pollution risks, requires the further study. This paper discusses and analyses the feasibility of the Nicaragua Canal in the context of its environmental impact and value as a shipping service. This paper aims to provide an important information reference to inform strategic decision-making among policymakers and stakeholders. Our research results indicate that the environmental complexity, economic costs and safety risks of building a new transoceanic canal are simply too high to justify the project.

Country watch: Nicaragua.

Pauw, J

1999-01-01

The Association of Workers for Education, Health and Social Integration (TESIS) works with commercial sex workers to control HIV and sexually transmitted diseases in Nicaragua through free condom distribution and education. Education includes group work, individual counseling, and demonstrations of correct condom use. Condoms are also distributed to the motels frequented by commercial sex workers. When the Condom Social Marketing (CSM) project in Central America started, it sold condoms of the same quality as the ones offered by TESIS; thus the condom donors reduced their donations, and in turn, TESIS lost its normal quota for free condom distribution. Because of this situation, TESIS dealt with a condom promotion scheme at a lower cost for the poorest women. Condom quality did not deteriorate as products only came with simpler packaging. TESIS fills the gap which CSM missed.

Malaria control in Nicaragua: social and political influences on disease transmission and control activities.

PubMed

Garfield, R

1999-07-31

Throughout Central America, a traditional malaria control strategy (depending on heavy use of organic pesticides) became less effective during the 1970s. In Nicaragua, an alternative strategy, based on frequent local epidemiological assessments and community participation, was developed in the 1980s. Despite war-related social instability, and continuing vector resistance, this approach was highly successful. By the end of the contra war, there finally existed organisational and ecological conditions that favoured improved malaria control. Yet the expected improvements did not occur. In the 1990s, Nicaragua experienced its worst recorded malaria epidemics. This situation was partly caused by the country's macroeconomic structural adjustment programme. Volunteers now take fewer slides and provide less treatment, malaria control workers are less motivated by the spirit of public service, and some malaria control stations charge for diagnosis or treatment. To "roll back malaria", in Nicaragua at least, will require the roll-back of some erroneous aspects of structural adjustment.

To identify perceived barriers to accessing reproductive health care according to the women of Ocotal, Nicaragua; describe their understanding of their reproductive rights; and document their opinions about Nicaragua's total ban on abortion. From May to June 2014, three focus group discussions were held in Spanish with 17 women from two different neighborhoods (barrios) in the city of Ocotal, Nicaragua. A semi-structured discussion guide with open-ended questions was employed to elucidate local perspectives regarding the focus group discussions themes. Serious obstacles including 1) violence against women, 2) machismo, 3) criticism from others, and 4) lack of communication and education limit women's ability to make their own reproductive health decisions. Women had a pervasive lack of knowledge about reproductive rights and the international human rights documents that define them. In addition, due to religious and cultural ideologies, most women supported the country's total ban on abortion in most circumstances, with the possible exception of rape. Both men and women in Ocotal should be encouraged to participate in community-level programs designed to reduce the impact of the following obstacles to receiving reproductive health care: 1) violence against women and machismo; 2) insufficient, non-standardized sexual education and information about reproductive rights; and 3) poor communication within families and the community at large. Any future public health campaigns to address women's reproductive health needs in Ocotal should implement these types of programs, at the neighborhood level, to reduce stigma surrounding sexual health and activity.

Perspective View with Landsat Overlay, Lakes Managua and Nicaragua

NASA Technical Reports Server (NTRS)

2002-01-01

This perspective view shows Lakes Managua and Nicaragua near the Pacific coast of Nicaragua. Lake Managua is the 65-kilometer (40-mile)-long fresh water lake in the foreground of this south-looking view, emptying via the Tipitapa River into the much larger Lake Nicaragua in the distance. The capital city of Managua, with a population of more than 500,000, is located along the southern shore of Lake Managua, the area with the highest population density in Nicaragua.

The physical setting of Lake Managua is dominated by the numerous volcanic features aligned in a northwest-southeast axis. The cone-like feature in the foreground is Momotombo, a 1,280-meter (4,199-foot)-high stratovolcano located on the northwest end of the lake. Two water-filled volcanic craters (Apoyegue and Jiloa volcanoes) reside on the Chiltepe Peninsula protruding into the lake from the west. Two volcanoes can also be seen on the island of Ometepe in Lake Nicaragua: El Maderas rising to 1,394 meters (4,573 feet) and the active El Conception at 1,610 meters (5,282 feet).

This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated two times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, S.D.

Elevation data used in this image was acquired by the SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne

Health-related outcomes of war in Nicaragua.

Since 1983, war in Nicaragua has slowed improvements in health which had developed rapidly from 1979-82. The rate of war-related deaths among Nicaraguans now exceeds that of the United States citizens in either the Vietnam War or World War II. Forty-two of the 84 documented war-related casualties among Nicaraguan health workers have been deaths. This high case fatality rate reflects the targeting of health workers by contra troops. The number of staff and services of the public medical system decreased by approximately 10 per cent from 1983 to 1985. Population movements, the establishment of new settlements, and war-related destruction of the primary health infrastructure are associated with recent epidemics of malaria, dengue, measles, and leishmaniasis. The estimated rate of infant mortality in Nicaragua, which had declined from 120 per 1,000 in 1978 to 76/1,000 live births in 1983, has since shown no further decline. Internationally mandated protections enjoyed by civilians and health workers during times of war do not appear to operate in this so-called "low intensity" conflict. Further declines in infant mortality, prevention of epidemics, and improvement in other health indicators will likely await the cessation of military hostilities. PMID:3565659

By and for women. Nicaragua's Si Mujer.

PubMed

1993-01-01

In Nicaragua, a group of women physicians and health professionals created an alternative health service for women. "Si Mujer" (Yes Woman), which stands for Integrated Services for Women, provides: 1) gynecologic services (comprehensive check-up, early cancer detection, sterility counseling, and AIDS and sexually transmitted disease [STD] prevention); 2) obstetric services (prenatal care, normal and high-risk pregnancy care, and family planning); 3) counseling (for women, couples, and families, and for victims of sexual violence); and 4) sex education and training (in reproductive health, gynecology, and sexuality). The non-profit organization collects fees according to ability to pay (11% pay nothing) and serves approximately 800 clients per month. Special programs provide services to teenagers and to men. While the training program began as a secondary effort, it is now as important as the direct service provision, with training activities reaching more than 1600 people in the first year through courses on such topics as sexuality, gender and power, AIDS and STD prevention, and cancer prevention. Si Mujer is one of more than 52 women's health centers in Nicaragua that have arisen to fill the gap left by the deterioration of public health services and which apply a gender perspective to the manner in which they approach their clients.

Influenza and Other Respiratory Viruses 5(1), 1–5. Background  Globally, respiratory infections are the primary cause of illness in developing countries, specifically among children; however, an etiological agent for many of these illnesses is rarely identified. Objectives  Our study aimed to estimate the frequency of human bocavirus (HBoV) infection among pediatric populations in Argentina, Nicaragua and Peru. Methods  We conducted a cross‐sectional study using stored samples of an influenza‐like illness surveillance program. Irrespective of previous diagnosis, nasopharyngeal or nasal swab specimens were randomly selected and tested using real‐time PCR from three sites during 2007 from patients younger than 6 years old. Results  A total of 568 specimens from Argentina (185), Nicaragua (192) and Peru (191) were tested. The prevalence of HBoV was 10·8% (95% CI: 6·3; 15·3) in Argentina, 33·3% in Nicaragua (95% CI: 26·6; 40·1) and 25·1% in Peru (95% CI: 18·9; 31·3). Conclusions  These findings demonstrate circulation of HBoV in Argentina, Nicaragua and Peru among children with influenza‐like symptoms enrolled in a sentinel surveillance program. PMID:21138534

Providing sanctuary for battered women: Nicaragua's casas de la mujer.

PubMed

Wessel, L; Campbell, J C

1997-01-01

A combination of participant observation and in-depth interviews (10 with key informants; 21 with battered women) was used to investigate wife battering in Nicaragua and the casas de la mujer, or women's centers, that have been established to help abused women. The results are presented within the context of the historical and structural realities of women's lives in Nicaragua and the sanctions and sanctuary framework of cultural analysis of wife battering. Nicaraguan wife battering is exacerbated in the context of cultural traditions of acceptance of wife beating, machismo, and the recent history of warfare. Findings about the relationship context and intervention outcomes were similar to those found in studies of battered women and shelters in the United States. The results were generally supportive of the framework, demonstrating the importance of women's solidarity groups, community sanctions against domestic violence, and sanctuary for battered women.

Objectives Investigate clinical and epidemiological factors of pediatric GII.4 norovirus infections in children with acute gastroenteritis (AGE) in Nicaragua between 1999 and 2015. Methods We retrospectively analyzed laboratory and epidemiologic data from 1,790 children ≤ 7 years with AGE from 6 hospitals in Nicaragua (n = 538), and 3 community clinics (n = 919) and households (n = 333) in León, between 1999 and 2015. Moreover, asymptomatic children from community clinics (n = 162) and households (n = 105) were enrolled. Norovirus was detected by real-time PCR and genotyped by sequencing the N-terminal and shell region of the capsid gene. Results Norovirus was found in 19% (n = 338) and 12% (n = 32) of children with and without AGE, respectively. In total, 20 genotypes including a tentatively new genotype were detected. Among children with AGE, the most common genotypes were GII.4 (53%), GII.14 (7%), GII.3 (6%) and GI.3 (6%). In contrast, only one (1.4%) GII.4 was found in asymptomatic children. The prevalence of GII.4 infections was significantly higher in children between 7 and 12 months of age. The prevalence of GII.4 was lowest in households (38%), followed by community clinics (50%) and hospitals (75%). Several different GII.4 variants were detected and their emergence followed the global temporal trend. Conclusions Overall our study found the predominance of pediatric GII.4 norovirus infections in Nicaragua mostly occurring in children between 7 and 12 months of age, implicating GII.4 as the main norovirus vaccine target.

The Central America volcanic front provides a unique opportunity to study hydrothermal inputs and their interaction and mixing with modern meteoric waters. The objectives of this study were to: a) characterize the isotopic composition (δ18O, δ2H, d-excess, and lc-excess) of hydrothermal/volcanic systems, b) analyze the influence of kinetic fractionation and meteoric water inputs in the isotopic composition of hydrothermal waters, and c) estimate the 'andesitic water' contribution (recycled subduction fluids) within the volcanic front of Nicaragua and Costa Rica. Hydrothermal evaporation lines are described as: δ2H = 4.7·δ18O - 13.0 (Costa Rica) and δ2H = 2.7·δ18O - 31.6 (Nicaragua). These regressions are significantly (p < 0.001) deviated from their respective meteoric water lines: δ2H = 7.6·δ18O + 7.4 (Costa Rica) and δ2H = 7.4·δ18O + 5.2 (Nicaragua). The greater rainfall inputs in Costa Rica with respect to Nicaragua, resulted in the attenuation of the evaporative effect as observed in the strong bimodal distribution of the hydrothermal waters, which can be divided in fluids: a) isotopically-close to meteoric conditions and b) isotopically-altered by the interaction with recycled subduction fluids and kinetic fractionation. The latter is clearly depicted in the significantly (p < 0.001) low d-excess and lc-excess median values between Costa Rica (+ 5.10‰, - 5.25‰) and Nicaragua (- 2.42‰, - 10.65‰), respectively. Poor correlations between δ18O/δ2H and the elevation gradient emphasize that the contribution of recycled subduction fluids and subsequent surface kinetic fractionation are the main drivers of the isotopic departure from the orographic distillation trend captured in the rainfall isoscapes. End-member mixing calculations resulted in a significant difference (p < 0.001) between the mean 'andesitic water' contribution to the hydrothermal systems of 15.3 ± 10.8 (%, ± 1σ) (Nicaragua) and 19.7 ± 10.3 (%, ± 1σ) (Costa Rica).

This is the first assessment of catch rates for the legal, artisanal green turtle, Chelonia mydas, fishery in Caribbean Nicaragua. Data were collected by community members, monitoring up to 14 landing sites from 1991 to 2011. We examined take levels, and temporal and spatial variability in catch rates for the overall fishery, by region, and community using General Additive Mixed Models (GAMMs). More than 171,556 green turtles were killed during the period, with a mean estimated minimum 8,169±2,182 annually. There was a statistically significant decline in catch rates overall. Catch rates peaked in 1997 and 2002, followed by a downward trend, particularly from mid-2008 to the end of the study period. Similar downward trends were evident in both study regions. Community specific catch rate trends also indicated declines with decreases ranging from 21% to 90%. Decrease in catch rates in Nicaragua is cause for concern even though the principal source rookery at Tortuguero, Costa Rica, shows an increase in nesting activity. Explanations for the apparent discrepancy between the increasing trend at Tortuguero and decreasing catch rate trends in Nicaragua include: i) an increase in reproductive output, ii) insufficient time has passed to observe the impact of the fishery on the rookery due to a time lag, iii) changes in other segments of the population have not been detected since only nesting activity is monitored, iv) the expansive northern Nicaragua foraging ground may provide a refuge for a sufficient portion of the Tortuguero rookery, and/or v) a larger than expected contribution of non-Tortuguero rookeries occurring in Nicaragua turtle fishing areas. Our results highlight the need for close monitoring of rookeries and in-water aggregations in the Caribbean. Where consumptive use still occurs, nations sharing this resource should implement scientifically based limits on exploitation to ensure sustainability and mitigate impacts to regional population diversity.

To examine the costs of implementing kangaroo mother care (KMC) in a referral hospital in Nicaragua, including training, implementation, and ongoing operating costs, and to estimate the economic impact on the Nicaraguan health system if KMC were implemented in other maternity hospitals in the country. After receiving clinical training in KMC, the implementation team trained their colleagues, wrote guidelines for clinicians and education material for parents, and ensured adherence to the new guidelines. The intervention began September 2010 The study compared data on infant weight, medication use, formula consumption, incubator use, and hospitalization for six months before and after implementation. Cost data were collected from accounting records of the implementers and health ministry formularies. A total of 46 randomly selected infants before implementation were compared to 52 after implementation. Controlling for confounders, neonates after implementation had lower lengths of hospitalization by 4.64 days (P = 0.017) and 71% were exclusively breastfed (P < 0.001). The intervention cost US$ 23 113 but the money saved with shorter hospitalization, elimination of incubator use, and lower antibiotic and infant formula costs made up for this expense in 1 - 2 months. Extending KMC to 12 other facilities in Nicaragua is projected to save approximately US$ 166 000 (based on the referral hospital incubator use estimate) or US$ 233 000 after one year (based on the more conservative incubator use estimate). Treating premature and low-birth-weight infants in Nicaragua with KMC implemented as a quality improvement program saves money within a short period even without considering the beneficial health effects of KMC. Implementation in more facilities is strongly recommended.

Health care in Nicaragua: a social and historical perspective.

PubMed

Petrack, E M

1984-10-01

To facilitate understanding of the advances in health care in Nicaragua since 1979, this discussion examines them within a historical framework. Nicaragua was occupied by US marines almost continuously from 1909-33. In 1933, their withdrawal left in power the US backed National Guard and the 1st dictator, Anastasio Somoza Garcia. Health conditions under the Somoza regime are difficult to evaluate because lack of data and underreporting were the norm. The health care system under Somoza was administered by 23 separate agencies, including the National Social Security Institute (INSS), a national Ministry of Health, independent local health ministries, and autonomous public hospital governing boards. On July 19, 1979, the dictatorship was overthrown in a popular uprising. Somoza left behind a foreign debt of 1.6 billion dollars, which the Sandinista Front for National Liberation (FSLN) needed to honor to qualify for needed loans. Following Somoza's defeat, the new government faced the problem of how to care for the tens of thousands of persons wounded and how to distribute the aid and medical supplies coming in from other countries. The key to achieving these tasks was popular participation and organization. By the early part of 1980, the new government was addressing more directly the organization of the health care system. Unlike the fragmented services under Somoza, health care in the new Nicaragua fell under the control of a unified Ministry of Health (MINSA). In 1980, the FSLN initiated an intensive campaign against illiteracy, 100,000 young Nicaraguans, called "brigadistas," were trained and sent around the country to teach basic reading and writing. In addition, 1 out of 10 was trained in elementary health principles. They were responsible for educating others about hygiene and basic sanitation as well as distributing antimalarial medication. 5 popular Health Campaigns were waged during 1981 against polio; measles, diphtheria, pertussis, and tetanus; rabies

To evaluate the cost-effectiveness of human papillomavirus (HPV) DNA testing (versus Papanicolaou (Pap)-based screening) for cervical cancer screening in Nicaragua. A previously developed Monte Carlo simulation model of the natural history of HPV infection and cervical cancer was calibrated to epidemiological data from Nicaragua. Cost data inputs were derived using a micro-costing approach in Carazo, Chontales and Chinandega departments; test performance data were from a demonstration project in Masaya department. Nicaragua's public health sector facilities. Women aged 30-59 years. Screening strategies included (1) Pap testing every 3 years, with referral to colposcopy for women with an atypical squamous cells of undetermined significance or worse result ('Pap'); (2) HPV testing every 5 years, with referral to cryotherapy for HPV-positive eligible women (HPV cryotherapy or 'HPV-Cryo'); (3) HPV testing every 5 years, with referral to triage with visual inspection with acetic acid (VIA) for HPV-positive women ('HPV-VIA'); and (4) HPV testing every 5 years, with referral to Pap testing for HPV-positive women ('HPV-Pap'). Reduction in lifetime risk of cancer and incremental cost-effectiveness ratios (ICER; 2015 US$ per year of life saved (YLS)). HPV-based screening strategies were more effective than Pap testing. HPV-Cryo was the least costly and most effective strategy, reducing lifetime cancer risk by 29.5% and outperforming HPV-VIA, HPV-Pap and Pap only, which reduced cancer risk by 19.4%, 12.2% and 10.8%, respectively. With an ICER of US$320/YLS, HPV-Cryo every 5 years would be very cost-effective using a threshold based on Nicaragua's per capita gross domestic product of US$2090. Findings were robust across sensitivity analyses on test performance, coverage, compliance and cost parameters. HPV testing is very cost-effective compared with Pap testing in Nicaragua, due to higher test sensitivity and the relatively lower number of visits required. Increasing

Reinforcing marginality? Maternal health interventions in rural Nicaragua.

PubMed

Kvernflaten, Birgit

2017-06-23

To achieve Millennium Development Goal 5 on maternal health, many countries have focused on marginalized women who lack access to care. Promoting facility-based deliveries to ensure skilled birth attendance and emergency obstetric care has become a main measure for preventing maternal deaths, so women who opt for home births are often considered 'marginal' and in need of targeted intervention. Drawing upon ethnographic data from Nicaragua, this paper critically examines the concept of marginality in the context of official efforts to increase institutional delivery amongst the rural poor, and discusses lack of access to health services among women living in peripheral areas as a process of marginalization. The promotion of facility birth as the new norm, in turn, generates a process of 're-marginalization', whereby public health officials morally disapprove of women who give birth at home, viewing them as non-compliers and a problem to the system. In rural Nicaragua, there is a discrepancy between the public health norm and women's own preferences and desires for home birth. These women live at the margins also in spatial and societal terms, and must relate to a health system they find incapable of providing good, appropriate care. Strong public pressure for institutional delivery makes them feel distressed and pressured. Paradoxically then, the aim of including marginal groups in maternal health programmes engenders resistance to facility birth.

We report on a pilot study to assess the effects of low intensity war in Nicaragua on the health of the civilian population. The study compared data from two regions in Nicaragua, one in an area of intense conflict, the other further removed from the war's violence. Information was obtained from a questionnaire administered to female heads of randomly selected households; structured interviews with community leaders and health workers; group discussions with community residents; and a review of regional and municipal death records. Height and mid-upper arm circumference of children were measured, and immunization records reviewed. The war has had a serious negative effect on the lives of the civilian population in both the war zone and the non-war zone, with the effects most severe in the war zone. In both communities, over half of the respondents reported the death of a friend or relative. In the war zone community, over one-fourth of respondents reported attacks on family members in non-combat situations around their homes. Death by firearms was the leading cause of death in persons over age 6 in the war zone. Vaccination coverage, nutritional indices, and familial disruption were worse in the war zone community. The findings suggest that continued funding of the Nicaraguan contra forces by the United States may be harming the ostensible beneficiaries of that policy, and that use of such low intensity conflict as a foreign policy tool should be questioned.

Nicaragua is one of the poorest nations in the Western Hemisphere. The health of the population suffers as a result of poor nutrition, epidemic diseases, natural and manmade disasters, sporadic violence, urban industrial growth, and inadequate government funding for even basic medical equipment and supplies. Within this environment, emergency services development has been recognized as an important and cost-effective public health intervention. In recent years, government and nongovernmental agencies working together have had a dramatic positive impact on the quality of emergency care provided.

The focus of the present study was to find out which native plants were most suited for soil bioengineering purposes, particularly in the realization of riverbank protection in Nicaragua. Furthermore, we have also been aiming at economic efficiency. These techniques are appropriate for sustainable watershed management especially in underdeveloped countries. Concerning the plants to be used we experimented four native species. Gliricidia Sepium, Cordia dentata and Jatropha curcas are suitable for soil bioengineering more than Bursera Simaruba. Economically speaking, the sustainability of such interventions in underdeveloped countries, has been shown by the evaluation of the cost of riverbank protection using vegetated crib-walls in Nicaragua compared to the cost in different contexts.

Common bean (Phaseolus vulgaris) is an annual grain legume that was domesticated in Mesoamerica (Central America) and the Andes. It is currently grown widely also on other continents including Africa. We surveyed seedborne viruses in new common bean varieties introduced to Nicaragua (Central America) and in landraces and improved varieties grown in Tanzania (eastern Africa). Bean seeds, harvested from Nicaragua and Tanzania, were grown in insect-controlled greenhouse or screenhouse, respectively, to obtain leaf material for virus testing. Equal amounts of total RNA from different samples were pooled (30-36 samples per pool), and small RNAs were deep-sequenced (Illumina). Assembly of the reads (21-24 nt) to contiguous sequences and searches for homologous viral sequences in databases revealed Phaseolus vulgaris endornavirus 1 (PvEV-1) and PvEV-2 in the bean varieties in Nicaragua and Tanzania. These viruses are not known to cause symptoms in common bean and are considered non-pathogenic. The small-RNA reads from each pool of samples were mapped to the previously characterized complete PvEV-1 and PvEV-2 sequences (genome lengths ca. 14 kb and 15 kb, respectively). Coverage of the viral genomes was 87.9-99.9%, depending on the pool. Coverage per nucleotide ranged from 5 to 471, confirming virus identification. PvEV-1 and PvEV-2 are known to occur in Phaseolus spp. in Central America, but there is little previous information about their occurrence in Nicaragua, and no information about occurrence in Africa. Aside from Cowpea mild mosaic virus detected in bean plants grown from been seeds harvested from one region in Tanzania, no other pathogenic seedborne viruses were detected. The low incidence of infections caused by pathogenic viruses transmitted via bean seeds may be attributable to new, virus-resistant CB varieties released by breeding programs in Nicaragua and Tanzania.

The Costa Rica-Nicaragua subduction zone shows systematic along strike variation in arc chemistry, geology and seismic velocity and attenuation, presenting global extremes within a few hundred kilometres. In this study we use teleseismic and ambient noise derived surface wave tomography to produce a 3-D shear velocity model of the region. We use the 48 stations of the TUCAN array, and up to 96 events for the teleseismic Rayleigh wave inversion, and 20 months of continuous data for cross correlation to estimate Green's functions from ambient noise. In the shallow crust (0-15 km) we observe low shear velocities directly beneath the arc volcanos (< 3 km/s) with higher velocities in the back arc of Nicaragua. The anomalies are likely caused by heated crust, possibly intruded by magma. We observe > 40 km thick crust beneath the Costa Rican arc and the Nicaraguan Highlands, with thinned crust (~20 km) beneath the Nicaraguan Depression, with increasing crustal thickness in the back arc region. At mantle depths (55-120 km depth) we observe lower shear velocities (~2%) beneath the Nicaraguan arc and back arc relative to Costa Rica. This is well-correlated with a Vp/Vs anomaly beneath Nicaragua. The lower shear velocity beneath Nicaragua may indicate higher melt content in the mantle perhaps due to higher volatile flux from the slab. Finally, we observe a linear high velocity region at depths > 120 km parallel to the trench, which is consistent with the subducting slab.

[Distribution, surface and protected area of palm-swamps in Costa Rica and Nicaragua].

In Central America, palm swamps are known collectively as yolillales. These wetlands are usually dominated by the raffia palm Raphia taedigera, but also by the royal palm Manicaria saccifera and -in lower extensions- by the American oil palm Elaeis oleifera. The yolillales tend to be poor in woody species and are characteristic of regions with high rainfall and extensive hydroperiods, so they remain flooded most of the year. The dominance of large raffia palm leaves in the canopy, allow these environments to be distinguishable in aerial photographs, which consequently has helped to map them along most of their distribution. However, while maps depicting yolillales are available, the extent of their surface area, perimeter and connectivity remains poorly understood. This is particularly true for yolillales in Costa Rica and Nicaragua, countries that share a good proportion of palm dominated swaps in the Rio San Juan Basin. In addition, it is not known the actual area of these environments that is under any category of protection according to the conservation systems of both countries. As a first step to catalog yolillal wetlands in Costa Rica and Nicaragua, this paper evaluates cartographic maps to delineate yolillales in the region. A subsample of yolillales mapped in this study were visited and we geo-referenced them and evaluate the extent and condition of the swamp. A total of 110 883.2ha are classified as yolillales in Nicaragua, equivalent to 22% of wetland surface area recorded for that country (excluding the Cocibolca and Xolothn Lakes). In Costa Rica, 53 931.3ha are covered by these palm dominated swamps, which represent 16.24% of the total surface area covered by wetlands. About 47% of the area covered by yolillales in Nicaragua is under some category of protection, the largest extensions protected by Cerro Silva, Laguna Tale Sulumas and Indio Maiz Nature Reserves. In Costa Rica, 55.5% of the area covered by yolillal is located within protected areas

Leptospirosis is an epidemic-prone zoonotic disease that occurs worldwide. In Central America, leptospirosis outbreaks have been reported in almost all countries; Nicaragua in particular has faced several outbreaks. The objective of this study was to stratify the risk and identify “critical areas” for leptospirosis outbreaks in Nicaragua, and to perform an exploratory analysis of potential “drivers”. This ecological study includes the entire country (153 municipalities). Cases from 2004 to 2010 were obtained from the country’s health information system, demographic and socioeconomic variables from its Census, and environmental data from external sources. Criteria for risk stratification of leptospirosis were defined. Nicaragua reported 1,980 cases of leptospirosis during this period, with the highest percentage of cases (26.36%) in León, followed by Chinandega (15.35%). Among the 153 municipalities, 48 were considered critical areas, 85 were endemic and 20 silent. Using spatial and statistical analysis, the variable presenting the most evident pattern of association with critical areas defined by top quintile of incidence rate is the percentage of municipal surface occupied by the soil combination of cambisol (over pyroclastic and lava bedrock) and andosol (over a volcanic ashes foundation). Precipitation and percentage of rural population are also associated with critical areas. This methodology and findings could be used for Nicaragua’s Leptospirosis Intersectoral Plan, and to identify possible risk areas in other countries with similar drivers. PMID:23202822

Climate Change affects weather patterns and modifies meteorological extreme events like tropical cyclones, heavy rainfalls, dry events, extreme temperatures, etc. The aim of this study is to show the Climate Change projections over Nicaragua for the period 2010-2040 focused on precipitation and temperature. In order to obtain the climate change signal, the results obtained by modelling a past period (1980-2009) were compared with the ones obtained by modelling a future period (2010-2040). The modelling method was based on a dynamical downscaling, coupling global and regional models. The MPI-ESM-MR global climate model was selected due to the better performance over Nicaragua. Moreover, a detailed sensitivity analysis for different parameterizations and schemes of the Weather Research and Forecast (WRF-ARW) model was made to minimize the model uncertainty. To evaluate and validate the methodology, a comparison between model outputs and satellite measurements data was realized. The results show an expected increment of the temperature and an increment of the number of days per year with temperatures higher than 35°C. Monthly precipitation patterns will change although annual total precipitation will be similar. In addition, number of dry days are expected to increase.

After the civil war and the Hurricane-Mitch disaster, cattlemen in Nicaragua were forced to transport their cattle from lowland areas to higher, dryer areas of the country. These areas are natural ecological niches for the cattle grub Dermatobia hominis (L. Jr.) (Diptera: Cuterebridae). To determine the importance of this infestation, the Agricultural and Livestock-Forestry Ministry selected a central area of Nicaragua to run a pioneer survey program to acquire information about hosts involved, number of cases, treatments applied and general knowledge of 42 farmers about the life cycle of the parasite. The subjects were either farm owners or farm managers. Ninety-five percentage of the farms indicated cases of D. hominis infestation in their animals, with cattle being the most affected host (100% of the affected farms). There was poor understanding of the D. hominis life cycle, vectors and control methods. A misuse of insecticides for the treatment of larval infestation by D. hominis was indicated.

Crustal and mantle shear velocity structure of Costa Rica and Nicaragua from ambient noise and teleseismic Rayleigh wave tomography

The Costa Rica-Nicaragua subduction zone shows systematic along strike variation in arc chemistry, geology, tectonics and seismic velocity and attenuation, presenting global extremes within a few hundred kilometres. In this study, we use teleseismic and ambient noise derived surface wave tomography to produce a 3-D shear velocity model of the region. We use the 48 stations of the TUCAN array, and up to 94 events for the teleseismic Rayleigh wave inversion, and 18 months of continuous data for cross correlation to estimate Green's functions from ambient noise. In the shallow crust (0-15 km) we observe low-shear velocities directly beneath the arc volcanoes (<3 km s-1) and higher velocities in the backarc of Nicaragua. The anomalies below the volcanoes are likely caused by heated crust, intruded by magma. We estimate crustal thickness by picking the depth to the 4 km s-1 velocity contour. We infer >40-km-thick crust beneath the Costa Rican arc and the Nicaraguan Highlands, thinned crust (˜20 km) beneath the Nicaraguan Depression, and increasing crustal thickness in the backarc region, consistent with receiver function studies. The region of thinned, seismically slow and likely weakened crust beneath the arc in Nicaragua is not localizing deformation associated with oblique subduction. At mantle depths (55-120 km depth) we observe lower shear velocities (up to 3 per cent) beneath the Nicaraguan arc and backarc than beneath Costa Rica. Our low-shear velocity anomaly beneath Nicaragua is in the same location as a low-shear velocity anomaly and displaced towards the backarc from the high VP/VS anomaly observed in body wave tomography. The lower shear velocity beneath Nicaragua may indicate higher melt content in the mantle perhaps due to higher volatile flux from the slab or higher temperature. Finally, we observe a linear high-velocity region at depths >120 km parallel to the trench, which is consistent with the subducting slab.

2012-01-01

Coffea arabica L. (arabica coffee), the only tetraploid species in the genus Coffea, represents the majority of the world's coffee production and has a significant contribution to Nicaragua's economy. The present paper was conducted to determine the genetic diversity of arabica coffee in Nicaragua for its conservation and breeding values. Twenty-six populations that represent eight varieties in Nicaragua were investigated using simple sequence repeat (SSR) markers. A total of 24 alleles were obtained from the 12 loci investigated across 260 individual plants. The total Nei's gene diversity (H T) and the within-population gene diversity (H S) were 0.35 and 0.29, respectively, which is comparable with that previously reported from other countries and regions. Among the varieties, the highest diversity was recorded in the variety Catimor. Analysis of variance (AMOVA) revealed that about 87% of the total genetic variation was found within populations and the remaining 13% differentiate the populations (F ST = 0.13; P < 0.001). The variation among the varieties was also significant. The genetic variation in Nicaraguan coffee is significant enough to be used in the breeding programs, and most of this variation can be conserved through ex situ conservation of a low number of populations from each variety.

Dengue is an emerging infectious disease of global significance. Suspected dengue, especially in children in Nicaragua's heavily-urbanized capital of Managua, has been well documented, but unsuspected dengue among children and adults with undifferentitated fever has not. To prospectively study dengue in semi-urban and rural western Nicaragua, we obtained epidemiologic and clinical data as well as acute and convalescent sera (2 to 4 weeks after onset of illness) from a convenience sample (enrollment Monday to Saturday daytime to early evening) of consecutively enrolled patients (n = 740) aged ≥ 1 years presenting with acute febrile illness. We tested paired sera for dengue IgG and IgM and serotyped dengue virus using reverse transcriptase-PCR. Among 740 febrile patients enrolled, 90% had paired sera. We found 470 (63.5%) were seropositive for dengue at enrollment. The dengue seroprevalance increased with age and reached >90% in people over the age of 20 years. We identified acute dengue (serotypes 1 and 2) in 38 (5.1%) patients. Only 8.1% (3/37) of confirmed cases were suspected clinically. Dengue is an important and largely unrecognized cause of fever in rural western Nicaragua. Since Zika virus is transmitted by the same vector and has been associated with severe congenital infections, the population we studied is at particular risk for being devastated by the Zika epidemic that has now reached Central America.

2016-01-01

Common bean (Phaseolus vulgaris L.) is an important legume with high nutritional value. In Nicaragua, certified healthy seeds of local bean varieties are not available, and seedborne fungi have gained little attention. Here, were surveyed seedborne pathogenic fungi in an important local bean cultivar, 'INTA Rojo'. Beans grown in the four main production areas in Nicaragua (Boaco, Carazo, Estelí, Matagalpa) for future use as seed stock were sampled from four seed storehouses and six seed lots. A total of 133 fungal strains were isolated from surface-sterilized beans and inoculated to healthy lima beans (Phaseolus lunatus) under controlled conditions. Eighty-seven isolates caused symptoms of varying severity in the seedlings, including discoloration, necrotic lesions, cankers, rot, and lethal necrosis. Pathogenic isolates were divided into eight phenotypically distinguishable groups based on morphology and growth characteristics on artificial growth medium, and further identified by analysis of the internal transcribed spacer sequences (ITS1 and ITS2) of the ribosomal RNA genes. The pathogenic isolates belonged to eight genera. Fusarium spp. (F. chlamydosporum, F. equiseti, F. incarnatum), Lasiodiplodia theobromae, Macrophomina phaseolina, and Penicillium citrinum were the most damaging and common fungi found in the seed lots. Furthermore, Corynespora cassiicola, Colletotrichum capsisi, Colletotrichum gloeosporioides, Aspergillus flavus, and Diaporthe sp. (Phomopsis) were seedborne in cultivar 'INTA Rojo' and found to be pathogenic to bean seedlings. This study reveals, for the first time, many seedborne pathogenic fungi in beans in Nicaragua; furthermore, prior to this study, little information was available concerning F. equiseti, F. incarnatum, L. theobromae, C. cassiicola, and Diaporthe spp. as seedborne pathogens of common bean. Our results lay the basis for developing diagnostic tools for seed health inspection and for further study of the epidemiology

Intercultural bilingual education in Nicaragua: Contextualisation for improving the quality of education

NASA Astrophysics Data System (ADS)

Valiente Catter, Teresa

2011-12-01

For the past 35 years, various models of intercultural bilingual education (IBE) have been implemented in Latin American schools and adult education. While Spanish is the official language in Nicaragua, many indigenous languages, such as Miskito and Sumo-Mayangna, are also spoken - especially in the Atlantic coastal region. The Nicaraguan Ministry of Education, Culture and Sport recognises the need for a flexible curriculum that reflects individual local and regional linguistic and socio-cultural characteristics, through the use of mother tongue and second language learning. The contextualisation model applied in the Atlantic coastal region of Nicaragua is therefore based on the use of a languages strategy in preparing textbooks and basic technical materials with an IBE approach, as part of the process of improving the quality of education. Thus intercultural communication is enhanced, and the need to strengthen the systematic teaching of languages, differentiating between mother tongue, second language and foreign language, is recognised. As well as explaining the contextualisation process in detail, this article discusses the conceptual differences between intercultural bilingual education (IBE) and bilingual intercultural education (BIE). The paper concludes with several recommendations for the further development of BIE in Latin America.

Lahar hazards at Mombacho Volcano, Nicaragua

Mombacho volcano, at 1,350 meters, is situated on the shores of Lake Nicaragua and about 12 kilometers south of Granada, a city of about 90,000 inhabitants. Many more people live a few kilometers southeast of Granada in 'las Isletas de Granada and the nearby 'Peninsula de Aseses. These areas are formed of deposits of a large debris avalanche (a fast moving avalanche of rock and debris) from Mombacho. Several smaller towns with population, in the range of 5,000 to 12,000 inhabitants are to the northwest and the southwest of Mombacho volcano. Though the volcano has apparently not been active in historical time, or about the last 500 years, it has the potential to produce landslides and debris flows (watery flows of mud, rock, and debris -- also known as lahars when they occur on a volcano) that could inundate these nearby populated areas. -- Vallance, et.al., 2001

Women (especially mothers) are theorized as critical to reducing household food insecurity through their work and caregiver roles. The present study tests these assumptions, assessing how maternal economic and social resources are associated with food insecurity in households with young children. Data from a population-based sample of households was collected in León, Nicaragua (n 443). Data include a newly validated measure of household food insecurity (ELCSA), maternal resource measures, and household economic status and demographics. Regression analysis tests the statistical associations (P<0·05) of maternal resources with household, adult-specific and child-specific food insecurity. Municipality of León, Nicaragua. Households with children aged 3-11 years in rural and urban León. Only 25% of households with young children were food secure, with 50% mildly food insecure and 25% moderately/severely food insecure. When mothers contributed substantially to household income, the odds of moderate/severe household food insecurity were 34% lower than when their spouse/partner was the main provider. The odds of food insecurity were 60% lower when mothers managed household money, 48% lower when mothers had a secondary (v. primary) education, 65% higher among single mothers and 16% lower with each indicator of social support. Results were similar for adult- and child-specific food insecurity. This research provides new evidence that maternal economic and social resources are important for reducing household food insecurity and adult- and child-specific food insecurity. Women's social status, social support and access to economic resources need to be enhanced as a part of policies aimed to reduce food insecurity in high-poverty settings.

Most children with cancer live in resource-limited countries where malnutrition is often prevalent. We identified the relationship between malnutrition and treatment-related morbidity (TRM), abandonment of therapy, and survival of children with cancer in Nicaragua to better inform targeted nutritional interventions. We conducted a retrospective review of patients aged 6 months to 18 years with newly diagnosed acute lymphoblastic leukemia, acute myeloid leukemia (AML), Wilms tumor, Hodgkin lymphoma, or Burkitt lymphoma (BL) who were treated between January 1, 2004, and December 31, 2007 at Children's Hospital Manuel de Jesus Rivera in Managua, Nicaragua. Statistical analysis examined the relations among nutritional status and cancer type, risk category, TRM, and event-free survival (EFS). Sixty-seven percent of patients (189/282) were malnourished at diagnosis. Malnutrition was highest among patients with Wilms tumor (85.7%), BL (75%), and AML (74.3%). A total of 92.2% of patients (225/244) experienced morbidity during the first 90 days. Malnutrition was associated with severe infection (P = 0.033). Severely malnourished patients had ≥grade 3 TRM on more days (P = 0.023) and were more likely to experience severe TRM on >50% of days (P = 0.032; OR, 3.27 [95% CI, 1.05-10.16]). Malnourished patients had inferior median EFS (2.25 vs. 5.58 years; P = 0.049), and abandoned therapy more frequently (P = 0.015). In Nicaragua, pediatric oncology patients with malnutrition at diagnosis experienced increased TRM, abandoned therapy more frequently, and had inferior EFS. Standardized nutritional evaluation of patients with newly diagnosed cancer and targeted provision of nutritional support are essential to decrease TRM and improve outcomes. © 2017 Wiley Periodicals, Inc.

On 27 August 2012 (04:37 UTC, 26 August 10:37 p.m. local time) a magnitude M w = 7.3 earthquake occurred off the coast of El Salvador and generated surprisingly large local tsunami. Following the event, local and international tsunami teams surveyed the tsunami effects in El Salvador and northern Nicaragua. The tsunami reached a maximum height of ~6 m with inundation of up to 340 m inland along a 25 km section of coastline in eastern El Salvador. Less severe inundation was reported in northern Nicaragua. In the far-field, the tsunami was recorded by a DART buoy and tide gauges in several locations of the eastern Pacific Ocean but did not cause any damage. The field measurements and recordings are compared to numerical modeling results using initial conditions of tsunami generation based on finite-fault earthquake and tsunami inversions and a uniform slip model.

Nicaragua's HIV epidemic is concentrated among men who have sex with men. Nevertheless, the increasing number of HIV cases among heterosexuals, high levels of poverty and migration rates, and incomplete epidemiological data suggest the need to improve the understanding of the epidemic. To examine the prevalence of HIV-related knowledge, attitudes, and sexual risk-taking behaviors, and their predictors among the adult population. A community-based cross-sectional survey was conducted in 2009 among 520 participants ages 15-49 from an ongoing Health and Demographic Surveillance System in Nicaragua. Bivariate analysis and adjusted prevalence ratios were use to examine factors associated with HIV-related knowledge, attitudes, and sexual behavior. Contributing factors for risk-taking behaviors included cognitive, psychosocial, and emotional elements. Insufficient knowledge affecting the accurate assessment of HIV risk were low educational level, poverty, and rural origin, especially among females. Recognizing risk was not sufficient to promote safer sex: 90% of the females and 70% of the males who reported being sexually active in the past year did not use condoms during their last sexual encounter. Inconsistent condom use among men was associated with older age, long-term relationships, and lack of awareness about acquiring HIV infection. Interventions to reduce social-structural contextual factors in Nicaragua are needed so that individuals may adopt and maintain HIV risk reduction strategies. Increased gender-specific HIV education and skills-building programs need to be implemented. Sensitive mass media messages may also increase the knowledge of HIV and AIDS, and serve to encourage protective attitudes and behaviors. Copyright © 2012 Elsevier B.V. All rights reserved.

Landslides in Nicaragua - Mapping, Inventory, Hazard Assessment, Vulnerability Reduction, and Forecasting Attempts

Dévoli, G.; Strauch, W.; Álvarez, A.; Muñoz, A.; Kjekstad, O.

2009-04-01

A successful landslide hazard and risk assessment requires awareness and good understanding of the potential landslide problems within the geographic area involved. However, this requirement is not always met in developing countries where population, scientific community, and the government may not be aware of the landslide threat. The landslide hazard assessment is often neglected or is based on sparse and not well documented technical information. In Nicaragua (Central America), the basic conditions for landslide hazard and risk assessment were first created after the catastrophic landslides triggered by Hurricane Mitch in October 1998. A single landslide took the life of thousands of people at Casita volcano forcing entire communities to be evacuated or relocated and, furthermore, thousands of smaller landslides caused loss of fertile soils and pasture lands, and made serious damages to the infrastructure. Since those events occurred, the public awareness has increased and the country relies now on new local and national governmental laws and policies, on a number of landslide investigations, and on educational and training programs. Dozens of geologists have been capacitated to investigate landslide prone areas, The Instituto Nicaragüense de Estudios Territoriales (INETER), governmental geo-scientific institution, has assumed the responsibility to help land-use planners and public officials to reduce geological hazard losses. They are committed to work cooperatively with national, international, and local agencies, universities and the private sector to provide scientific information and improve public safety through forecasting and warnings. However, in order to provide successful long-term landslide hazard assessment, the institutions must face challenges related to the scarcity and varied quality of available landslide information; collection and access to dispersed data and documents; organization of landslide information in a form that can be easy to

Fertility after natural disaster: Hurricane Mitch in Nicaragua

This investigation evaluates the effect of Hurricane Mitch on women’s reproductive outcomes throughout Nicaragua. This research aim is achieved by analyzing a unique Nicaraguan Living Standards Measurement Study panel dataset that tracks women’s fertility immediately before and at two time points after Hurricane Mitch, combined with satellite-derived municipality-level precipitation data for the 10-day storm period. Results show higher odds of post-disaster fertility in municipalities receiving higher precipitation levels in the immediate post-Hurricane Mitch period. However, fertility normalizes between disaster and non-disaster areas four to six years after the storm. These findings suggest that the disruptive effects of a natural disaster such as Hurricane Mitch can have an initial stimulative effect on fertility but the effect is ephemeral. PMID:28694556

Brune, Nancy E; Bossert, Thomas

Studies of social capital have focused on the static relationship between social capital and health, governance and economic conditions. This study is a first attempt to evaluate interventions designed to improve the levels of social capital in post-conflict communities in Nicaragua and to relate those increases to health and governance issues. The two-year study involved a baseline household survey of approximately 200 households in three communities in Nicaragua, the implementation of systematic interventions designed to increase social capital in two of the locales (with one control group), and a second household survey administered two years after the baseline survey. We found that systematic interventions promoting management and leadership development were effective in improving some aspects of social capital, in particular the cognitive attitudes of trust in the communities. Interventions were also linked to higher levels of civic participation in governance processes. As in other empirical studies, we also found that higher levels of social capital were significantly associated with some positive health behaviors. The behavioral/structural components of social capital (including participation in groups and social networks) were associated with more desirable individual health behaviors such as the use of modern medicine to treat children's respiratory illnesses. Attitudinal components of social capital were positively linked to community health behaviors such as working on community sanitation campaigns. The findings presented here should be of interest to policy makers interested in health policy and social capital, as well as those working in conflict-ridden communities in the developing world.

The 2016 El Salvador-Nicaragua outer-rise earthquake (M w 6.9) generated a small tsunami observed at the ocean bottom pressure sensor, DART 32411, in the Pacific Ocean off Central America. The dispersive observed tsunami is well simulated using the linear Boussinesq equations. From the dispersive character of tsunami waveform, the fault length and width of the outer-rise event is estimated to be 30 and 15 km, respectively. The estimated seismic moment of 3.16 × 1019 Nm is the same as the estimation in the Global CMT catalog. The dispersive character of the tsunami in the deep ocean caused by the 2016 outer-rise El Salvador-Nicaragua earthquake could constrain the fault size and the slip amount or the seismic moment of the event.

To evaluate the duration of protection of pentavaent rotavirus vaccine (RV5) against rotavirus hospitalizations in Nicaragua, a developing country in Central America. We conducted a case-control study at 4 hospitals from 2007 through 2010, including 1016 children hospitalized with laboratory-confirmed rotavirus diarrhea, 4930 controls with nonrotavirus diarrhea (ie, "test-negative"), and 5627 controls without diarrhea. All cases and controls were aged ≥ 6 months and born after August 2006. Outcomes included odds of antecedent vaccination between case-patients and controls, and effectiveness of vaccination (1 - adjusted odds ratio [OR] × 100). Duration of protection was assessed by comparing effectiveness among children aged <1 year compared with ≥ 1 year. Indicators of socioeconomic conditions and nonrotavirus vaccination (oral polio vaccine and diphtheria/tetanus/pertussis/hepatitis A/hepatitis B) for test-negative controls were more comparable to the rotavirus case-patients than nondiarrhea controls. RV5 vaccination was associated with a significantly lower risk of rotavirus hospitalization by using test-negative controls (OR: 0.55; 95% confidence interval [CI]: 0.41-0.74) and nondiarrhea controls (OR: 0.30; 95% CI: 0.22-0.40). Risk of rotavirus hospitalization was twofold lower among RV5 vaccinated children aged <1 year (OR: 0.36; 95% CI: 0.22-0.57) compared with RV5 vaccinated children aged ≥ 1 year (OR: 0.70; 95% CI: 0.47-1.05). RV5 provided good protection against severe rotavirus disease in Nicaragua during the first year of life, when most severe and fatal rotavirus disease in developing countries occurs. However, the decline in protection with age warrants monitoring of disease among older children and consideration of a booster dose evaluation at the end of infancy.

The article analyzes various aspects of overall happiness expressed by 136 women in poverty who are victims of intimate partner violence (IPV) in Nicaragua, a country with low levels of development. The information was gathered using a structured interview. Results obtained show that despite the hardships they face, one half of the women in poverty who are victims of IPV say they are happy, and the vast majority are optimistic about their future. The main sources of happiness among the interviewees are in areas outside their economic life and are mainly associated with social relations.

Objective To examine the association between overweight and obesity and serum ferritin among women of reproductive age (15–49 years) in Nicaragua, considering the effect of α1-acid glycoprotein (AGP), a marker of inflammation. Design We analysed data from the 2004–05 Nicaraguan Integrated Surveillance System for Nutrition Interventions. Three logistic regression models were analysed with low serum ferritin (<15 μg/l) as the dependent variable: (i) overweight or obese status and covariates; (ii) model 1 plus AGP; and (iii) model 1 restricted to only women with normal AGP levels (≤1·0 g/l). Setting Nicaragua. Subjects Included in this analysis were 832 non-pregnant mother/caregivers (15–49 years) surveyed in 2004–2005. Results In the sample, prevalence of overweight and obesity was 31·8 % and 19·2 %, respectively, and 27·6 % had low serum ferritin. In model 1, the adjusted OR of low serum ferritin was 0·74 (95 % CI 0·52, 1·05) for overweight women and 0·42 (95 % CI 0·26, 0·65) for obese women. In model 2, AGP was significantly independently associated with low serum ferritin (adjusted OR=0·56, 95 % CI 0·34, 0·92) while the adjusted OR for overweight and obesity were largely unchanged. Excluding women with elevated AGP did not appreciably affect the relationship between overweight or obesity and low serum ferritin (model 3). Conclusions Overall, in this population of reproductive-age women, obese women were less likely to have low serum ferritin levels, and this was independent of inflammation as measured by AGP.

None of the sera from Iran and Nicaragua were HIV-antibody positive.

Reflections on curative health care in Nicaragua.

Slater, R G

1989-01-01

Improved health care in Nicaragua is a major priority of the Sandinista revolution; it has been pursued by major reforms of the national health care system, something few developing countries have attempted. In addition to its internationally recognized advances in public health, considerable progress has been made in health care delivery by expanding curative medical services through training more personnel and building more facilities to fulfill a commitment to free universal health coverage. The very uneven quality of medical care is the leading problem facing curative medicine now. Underlying factors include the difficulty of adequately training the greatly increased number of new physicians. Misdiagnosis and mismanagement continue to be major problems. The curative medical system is not well coordinated with the preventive sector. Recent innovations include initiation of a "medicina integral" residency, similar to family practice. Despite its inadequacies and the handicaps of war and poverty, the Nicaraguan curative medical system has made important progress. PMID:2705603

Gas measurements from the Costa Rica-Nicaragua volcanic segment suggest possible along-arc variations in volcanic gas chemistry

Obtaining accurate estimates of the CO2 output from arc volcanism requires a precise understanding of the potential along-arc variations in volcanic gas chemistry, and ultimately of the magmatic gas signature of each individual arc segment. In an attempt to more fully constrain the magmatic gas signature of the Central America Volcanic Arc (CAVA), we present here the results of a volcanic gas survey performed during March and April 2013 at five degassing volcanoes within the Costa Rica-Nicaragua volcanic segment (CNVS). Observations of the volcanic gas plume made with a multicomponent gas analyzer system (Multi-GAS) have allowed characterization of the CO2/SO2-ratio signature of the plumes at Poás (0.30±0.06, mean ± SD), Rincón de la Vieja (27.0±15.3), and Turrialba (2.2±0.8) in Costa Rica, and at Telica (3.0±0.9) and San Cristóbal (4.2±1.3) in Nicaragua (all ratios on molar basis). By scaling these plume compositions to simultaneously measured SO2 fluxes, we estimate that the CO2 outputs at CNVS volcanoes range from low (25.5±11.0 tons/day at Poás) to moderate (918 to 1270 tons/day at Turrialba). These results add a new information to the still fragmentary volcanic CO2 output data set, and allow estimating the total CO2 output from the CNVS at 2835±1364 tons/day. Our novel results, with previously available information about gas emissions in Central America, are suggestive of distinct volcanic gas CO2/ST (= SO2 + H2S)-ratio signature for magmatic volatiles in Nicaragua (∼3) relative to Costa Rica (∼0.5-1.0). We also provide additional evidence for the earlier theory relating the CO2-richer signature of Nicaragua volcanism to increased contributions from slab-derived fluids, relative to more-MORB-like volcanism in Costa Rica. The sizeable along-arc variations in magmatic gas chemistry that the present study has suggested indicate that additional gas observations are urgently needed to more-precisely confine the volcanic CO2 from the CAVA, and from

Objective To describe the prevalence of noncommunicable disease (NCD) risk factors (overweight/obesity, tobacco smoking, and alcohol consumption) and identify correlations between these and sociodemographic characteristics in western and central Nicaragua. Methods This was a cross-sectional study of 1 355 participants from six communities in Nicaragua conducted in September 2007–July 2009. Demographic and NCD risk-related health behavior information was collected from each individual, and their body mass index (BMI), blood pressure, diabetes status, and renal function were assessed. Data were analyzed using descriptive statistics, bivariate analyses, and (non-stratified and stratified) logistic regression models. Results Of the 1 355 study participants, 22.0% were obese and 55.1% were overweight/obese. Female sex, higher income, and increasing age were significantly associated with obesity. Among men, lifelong urban living correlated with obesity (Odds Ratio [OR] = 4.39, 1.18–16.31). Of the total participants, 31.3% reported ever smoking tobacco and 47.7% reported ever drinking alcohol. Both tobacco smoking and alcohol consumption were strikingly more common among men (OR = 13.0, 8.8–19.3 and 15.6, 10.7–22.6, respectively) and lifelong urban residents (OR = 2.42, 1.31–4.47 and 4.10, 2.33–7.21, respectively). Conclusions There was a high prevalence of obesity/overweight across all income levels. Women were much more likely to be obese, but men had higher rates of tobacco and alcohol use. The rising prevalence of NCD risk factors among even the poorest subjects suggests that an epidemiologic transition in underway in western and central Nicaragua whereby NCD prevalence is shifting to all segments of society.

The proposed interoceanic canal will connect the Caribbean Sea with the Pacific Ocean, traversing Lake Nicaragua, the major freshwater reservoir in Central America. If completed, the canal would be the largest infrastructure-related excavation project on Earth. In November 2015, the Nicaraguan government approved an environmental and social impact assessment (ESIA) for the canal. A group of international experts participated in a workshop organized by the Academy of Sciences of Nicaragua to review this ESIA. The group concluded that the ESIA does not meet international standards; essential information is lacking regarding the potential impacts on the lake, freshwater and marine environments, and biodiversity. The ESIA presents an inadequate assessment of natural hazards and socioeconomic disruptions. The panel recommends that work on the canal project be suspended until an appropriate ESIA is completed. The project should be resumed only if it is demonstrated to be economically feasible, environmentally acceptable, and socially beneficial.

Water-related diseases, particularly diarrhea, are major contributors to morbidity and mortality in developing countries. Monitoring water quality on a global scale is crucial to making progress in terms of population health. Traditional analytical methods are difficult to use in many regions of the world in low-resource settings that face severe water quality issues due to the inaccessibility of laboratories. This study aimed to evaluate a new low-cost method (the compartment bag test (CBT)) in rural Nicaragua. The CBT was used to quantify the presence of Escherichia coli in drinking water wells and aimed to determine the source(s) of any microbial contamination. Results indicate that the CBT is a viable method for use in remote rural regions. The overall quality of well water in Pueblo Nuevo, Nicaragua was deemed unsafe, and results led to the conclusion that animal fecal wastes may be one of the leading causes of well contamination. Elevation and depth of wells were not found to impact overall water quality. However rope-pump wells had a 64.1% reduction in contamination when compared with simple wells.

Maternity waiting homes and institutional birth in Nicaragua: policy options and strategic implications.

With the aim of promoting institutional births and reducing the high maternal and child mortality rates in rural and poor zones, the government of Nicaragua is supporting the creation of maternity waiting homes. This study analyzes that strategy and examines the factors associated with the use of maternity waiting homes and institutional birth. To that end, we apply a quantitative approach, by means of an econometric analysis of the data extracted from surveys conducted in 2006 on a sample of women and parteras or traditional birth attendants, as well as a qualitative approach based on interviews with key informants. Results indicate that although the operation of the maternity waiting homes is usually satisfactory, there is still room for improvement along the following lines: (i) disseminating information about the homes to both women and men, as the latter frequently decide the course of women's healthcare, and to parteras, who can play an important role in referring women; (ii) strengthening the postpartum care; (iii) ensuring financial sustainability by obtaining regular financial support from the government to complement contributions from the community; and (iv) strengthening the local management and involvement of the regional government. These measures might be useful for health policy makers in Nicaragua and in other developing countries that are considering this strategy. Copyright © 2011 John Wiley & Sons, Ltd.

Hygiene behaviour in rural Nicaragua in relation to diarrhoea.

Childhood diarrhoea is a leading cause of morbidity and mortality in Nicaragua. Amongst the risk factors for its transmission are 'poor' hygiene practices. We investigated the effect of a large number of hygiene practices on diarrhoeal disease in children aged <2 years and validated the technique of direct observation of hygiene behaviour. A prospective follow-up study was carried out in a rural zone of Nicaragua. From the database of a previously conducted case-control study on water and sanitation 172 families were recruited, half of which had experienced a higher than expected rate of diarrhoea in their children and the other half a lower rate. Hygiene behaviour was observed over two mornings and diarrhoea incidence was recorded with a calendar, filled out by the mother, and collected every week for 5 months. Of 46 'good' practices studied, 39 were associated with a lower risk of diarrhoea, five were unrelated and only for two a higher risk was observed. Washing of hands, domestic cleanliness (kitchen, living room, yard) and the use of a diaper/underclothes by the child had the strongest protective effect. Schooling (>3 years of primary school) and better economic position (possession of a radio) had a positive influence on general hygiene behaviour, education having a slightly stronger effect when a radio was present. Individual hygiene behaviour appeared to be highly variable in contrast with the consistent behaviour of the community as a whole. Feasible and appropriate indicators of hygiene behaviour were found to be domestic cleanliness and the use of a diaper or underclothes by the child. A consistent relationship between almost all hygiene practices and diarrhoea was detected, more schooling producing better hygiene behaviour. The high variability of hygiene behaviour at the individual level requires repeated observations (at least two) before and after the hygiene education in the event one wants to measure the impact of the campaign on the individual.

Forearc kinematics in obliquely convergent margins: Examples from Nicaragua and the northern Lesser Antilles

NASA Astrophysics Data System (ADS)

Turner, Henry L., III

In this study, I use surface velocities derived from GPS geodesy, elastic half-space dislocation models, and modeled Coulomb stress changes to investigate deformation in the over-riding plate at obliquely convergent margins at the leading and trailing edges of the Caribbean plate. The two principal study areas are western Nicaragua, where the Cocos plate subducts beneath the Caribbean plate, and the northern Lesser Antilles, where the North American plate subducts beneath the Caribbean plate. In Nicaragua, plate convergence is rapid at 84 mm yr1 with a small angle of obliquity of 10° along a slightly concave portion of the Middle America Trench. GPS velocities for the period from 2000 to 2004 from sites located in the Nicaraguan forearc confirmed forearc sliver motion on the order of ˜14 mm yr1 in close agreement with the value predicted by DeMets (2001). These results are presented here in Chapter 3 and were reported in Geophysical Research Letters (Turner et al., 2007). GPS observations made on sites located in the interior and on the eastern coast of Nicaragua during the same time period were combined with new data from eastern Honduras to help better constrain estimates of rigid Caribbean plate motion (DeMets et al., 2007). Slip approaching the plate convergence rate along the Nicaraguan and El Salvadoran sections of the Middle America Trench was quantitatively demonstrated by finite element modeling of this section of the plate interface using GPS velocities from our Nicaraguan network together with velocities from El Salvador and Honduras as model constraints (Correa-Mora, 2009). The MW 6.9 earthquake that ruptured the seismogenic zone offshore Nicaragua on October 9, 2004 resulted in coseismic displacements and post-seismic motion at GPS sites in the central part of the Nicaraguan forearc that currently prevent extension of interseismic time-series in this region. An elastic half-space dislocation model was used to estimate coseismic displacements at these

Health services reforms in revolutionary Nicaragua.

Garfield, R M; Taboada, E

1984-01-01

Before the Nicaraguan revolution of 1979, access to health services was largely limited to the affluent sectors of the urban population and the minority of workers with social security coverage. Repeated attempts at reform by organized medicine were ineffective. Since the revolution, a tremendous expansion in health services has occurred. The national health system receives approximately one-third of its funds from the social security system. Steadily increasing equity in access is a result of the promotion of primary care, health campaigns involving up to 10 per cent of the general population as volunteers, the use of paramedical aides, and foreign assistance. Private practice nevertheless remains strong. In the coming years, several complex issues must be examined, including: a balance in the number of nurses and doctors trained, the role of private practice, and the relationship of the Ministry of Health to the social security system. Further progress in health reforms may be delayed by the defensive war which Nicaragua is fighting on its northern and southern borders. Despite emergent health problems in the war zones, most of the innovative aspects of the health system remain intact as of this writing. PMID:6476169

Application of a CROPWAT Model to Analyze Crop Yields in Nicaragua

NASA Astrophysics Data System (ADS)

Doria, R.; Byrne, J. M.

2013-12-01

ABSTRACT Changes in climate are likely to influence crop yields due to varying evapotranspiration and precipitation over agricultural regions. In Nicaragua, agriculture is extensive, with new areas of land brought into production as the population increases. Nicaraguan staple food items (maize and beans) are produced mostly by small scale farmers with less than 10 hectares, but they are critical for income generation and food security for rural communities. Given that the majority of these farmers are dependent on rain for crop irrigation, and that maize and beans are sensitive to variations in temperature and rainfall patterns, the present study was undertaken to assess the impact of climate change on these crop yields. Climate data were generated per municipio representing the three major climatic zones of the country: the wet Pacific lowland, the cooler Central highland, and the Caribbean lowland. Historical normal climate data from 1970-2000 (baseline period) were used as input to CROPWAT model to analyze the potential and actual evapotranspiration (ETo and ETa, respectively) that affects crop yields. Further, generated local climatic data of future years (2030-2099) under various scenarios were inputted to the CROPWAT to determine changes in ETo and ETa from the baseline period. Spatial variability maps of both ETo and ETa as well as crop yields were created. Results indicated significant variation in seasonal rainfall depth during the baseline period and predicted decreasing trend in the future years that eventually affects yields. These maps enable us to generate appropriate adaptation measures and best management practices for small scale farmers under future climate change scenarios.

As abortion is illegal in Nicaragua, postcoital contraception is an important option for preventing pregnancy. Emergency contraceptive pills are available in Nicaraguan pharmacies over the counter, but pharmacy personnel's knowledge and attitudes about this method can affect access. A cross-sectional survey was conducted in Managua, Nicaragua's capital. Interviewers administered a semistructured questionnaire to 93 pharmacy employees to determine their knowledge of and attitudes toward emergency contraceptive pills. Descriptive statistics and cross-tabulations were used to examine responses of and differences between male and female employees. All participants knew about emergency contraceptive pills and reported experience selling them. The majority sold them at least once a week (92%), usually without a prescription (97%). Of participants who were aware that emergency contraceptive pills should be taken only after sexual intercourse, 45% knew that the pills can be taken up to three days afterward; none knew that the pills are effective up to five days afterward. More than one-third of all respondents (39%) thought the pills can induce abortion, and most overestimated contraindications and side effects. Large majorities believed the availability of emergency contraceptive pills discourages use of ongoing methods (75%), encourages sexual risk-taking (82%) and increases transmission of HIV and other STIs (76%). Sixty-three participants (68%) thought emergency contraceptive pills are necessary to reduce unwanted and unplanned pregnancy; 65% were willing to provide them to all women in need, although only 13% would provide them to minors. Managuan pharmacy personnel frequently dispense emergency contraceptive pills, but need additional education to accurately counsel women about the method.

1998-11-01

In October 1995, epidemic "hemorrhagic fever," without jaundice or renal manifestations, was reported in rural Nicaragua following heavy flooding; 2259 residents were evaluated for nonmalarial febrile illnesses (cumulative incidence, 6.1%) and 15 (0.7%) died with pulmonary hemorrhage. A case-control study found that case-patients were more likely than controls to have ever walked in creeks (matched odds ratio [MOR], 15.0; 95% confidence interval [CI], 1.7-132.3), have household rodents (MOR, 10.4; 95% CI, 1.1-97.1), or own dogs with titers >/=400 to Leptospira species (MOR, 23.4; 95% CI, 3.6-infinity). Twenty-six of 51 case-patients had serologic or postmortem evidence of acute leptospirosis. Leptospira species were isolated from case-patients and potential animal reservoirs. This leptospirosis epidemic likely resulted from exposure to flood waters contaminated by urine from infected animals, particularly dogs. Leptospirosis should be included in the differential diagnosis for nonmalarial febrile illness, particularly during periods of flooding or when pulmonary hemorrhage occurs.

Objectives To evaluate the cost-effectiveness of human papillomavirus (HPV) DNA testing (versus Papanicolaou (Pap)-based screening) for cervical cancer screening in Nicaragua. Design A previously developed Monte Carlo simulation model of the natural history of HPV infection and cervical cancer was calibrated to epidemiological data from Nicaragua. Cost data inputs were derived using a micro-costing approach in Carazo, Chontales and Chinandega departments; test performance data were from a demonstration project in Masaya department. Setting Nicaragua’s public health sector facilities. Participants Women aged 30–59 years. Interventions Screening strategies included (1) Pap testing every 3 years, with referral to colposcopy for women with an atypical squamous cells of undetermined significance or worse result (‘Pap’); (2) HPV testing every 5 years, with referral to cryotherapy for HPV-positive eligible women (HPV cryotherapy or ‘HPV-Cryo’); (3) HPV testing every 5 years, with referral to triage with visual inspection with acetic acid (VIA) for HPV-positive women (‘HPV-VIA’); and (4) HPV testing every 5 years, with referral to Pap testing for HPV-positive women (‘HPV-Pap’). Outcome measures Reduction in lifetime risk of cancer and incremental cost-effectiveness ratios (ICER; 2015 US$ per year of life saved (YLS)). Results HPV-based screening strategies were more effective than Pap testing. HPV-Cryo was the least costly and most effective strategy, reducing lifetime cancer risk by 29.5% and outperforming HPV-VIA, HPV-Pap and Pap only, which reduced cancer risk by 19.4%, 12.2% and 10.8%, respectively. With an ICER of US$320/YLS, HPV-Cryo every 5 years would be very cost-effective using a threshold based on Nicaragua’s per capita gross domestic product of US$2090. Findings were robust across sensitivity analyses on test performance, coverage, compliance and cost parameters. Conclusions HPV testing is very cost-effective compared with Pap testing in

To identify factors related to dropping out from tuberculosis treatment in health centers in the departments of Managua and Matagalpa, in Nicaragua. This study matched cases and controls (1:1 ratio) by age and by municipality of treatment. The 251 cases were patients over 15 years of age who had dropped out of tuberculosis treatment, and the 251 controls were patients who had completed pharmacotherapy, during the period of January 1998 to December 2001. Data were obtained on demographic and socioeconomic characteristics, lifestyle habits, and treatment characteristics. The variables were chosen and grouped using a hierarchical theoretical model. Conditional logistic regression analysis was used to calculate odds ratios (ORs) with 95% confidence intervals (95% CIs). The risk factors for dropping out of tuberculosis drug treatment were: male gender (OR, 2.51; 95% CI, 1.63 to 3.94), an unstable living situation or being homeless (OR, 3.08; 95% CI, 1.57 to 6.49), changing residence during the treatment period (OR, 4.22; 95% CI, 2.06 to 9.93), consuming alcoholic beverages (OR, 5.25; 95% CI, 2.43 to 12.94), using illegal drugs (OR, 5.25; 95% CI, 2.43 to 12.94), difficulty in access to the health services (OR, 2.64; 95% CI, 1.39 to 5.29), and a negative opinion of the health care received (OR, 5.33; 95% CI, 1.52 to 28.56). It is essential for the health services in Nicaragua to develop measures to reduce the risk of dropout from treatment. In particular, it is important for the health sector to work with community groups that can support the health sector's activities.

Water, sanitation, and hygiene (WaSH) in schools contributes to better health and educational outcomes among school-aged children. In 2012, UNICEF Nicaragua and partners conducted a cross-sectional survey of WaSH in 526 schools in 12 low socio-economic status municipalities in Nicaragua. The survey gathered information on: school characteristics; teacher and community participation; water and sanitation infrastructure; and hygiene education and habits. Survey results were analyzed for associations between variables. WaSH coverage was significantly higher in urban than rural areas. Presence of drinking water infrastructure (43%) was lower than sanitation infrastructure (64%). Eighty-one percent of schools had no hand washing stations and 74% of schools lacked soap. Sanitation facilities were not in use at 28% of schools with sanitation infrastructure and 26% of schools with water infrastructure had non-functional systems. Only 8% of schools had budgets to purchase toilet-cleaning supplies and 75% obtained supplies from students' families. This study generates transferable WaSH sector learnings and new insights from monitoring data. Results can be used by donors, service providers, and policy makers to better target resources in Nicaraguan schools.

Peña, R; Wall, S; Persson, L A

2000-01-01

OBJECTIVES: This study assessed the effect of poverty and social inequity on infant mortality risks in Nicaragua from 1988 to 1993 and the preventive role of maternal education. METHODS: A cohort analysis of infant survival, based on reproductive histories of a representative sample of 10,867 women aged 15 to 49 years in León, Nicaragua, was conducted. A total of 7073 infants were studied; 342 deaths occurred during 6394 infant-years of follow-up. Outcome measures were infant mortality rate (IMR) and relative mortality risks for different groups. RESULTS: IMR was 50 per 1000 live births. Poverty, expressed as unsatisfied basic needs (UBN) of the household, increased the risk of infant death (adjusted relative risk [RR] = 1.49; 95% confidence interval [CI] = 1.15, 1.92). Social inequity, expressed as the contrast between the household UBN and the predominant UBN of the neighborhood, further increased the risk (adjusted RR = 1.74; 95% CI = 1.12, 2.71). A protective effect of the mother's educational level was seen only in poor households. CONCLUSIONS: Apart from absolute level of poverty, social inequity may be an independent risk factor for infant mortality in a low-income country. In poor households, female education may contribute to preventing infant mortality. PMID:10630139

Since the Aedes aegypti mosquitoes that transmit dengue virus can breed in clean water, WHO-endorsed vector control strategies place sachets of organophosphate pesticide, temephos (Abate), in household water storage containers. These and other pesticide-dependent approaches have failed to curb the spread of dengue and multiple dengue virus serotypes continue to spread throughout tropical and subtropical regions worldwide. A feasibility study in Managua, Nicaragua, generated instruments, intervention protocols, training schedules and impact assessment tools for a cluster randomised controlled trial of community-based approaches to vector control comprising an alternative strategy for dengue prevention and control in Nicaragua and Mexico. The Camino Verde (Green Way) is a pragmatic parallel group trial of pesticide-free dengue vector control, adding effectiveness to the standard government dengue control. A random sample from the most recent census in three coastal regions of Guerrero state in Mexico will generate 90 study clusters and the equivalent sampling frame in Managua, Nicaragua will generate 60 clusters, making a total of 150 clusters each of 137-140 households. After a baseline study, computer-driven randomisation will allocate to intervention one half of the sites, stratified by country, evidence of recent dengue virus infection in children aged 3-9 years and, in Nicaragua, level of community organisation. Following a common evidence-based education protocol, each cluster will develop and implement its own collective interventions including house-to-house visits, school-based programmes and inter-community visits. After 18 months, a follow-up study will compare dengue history, serological evidence of recent dengue virus infection (via measurement of anti-dengue virus antibodies in saliva samples) and entomological indices between intervention and control sites. Our hypothesis is that informed community mobilisation adds effectiveness in controlling

The conversion of forest to pasture and other agricultural uses has increased interest in the role that small-scale agroforestry systems can play in linking sustainable agriculture to biodiversity conservation, particularly in rapidly developing areas of the tropics. Complementing the provisioning of natural resources (i.e. food, medicine, lumber), agroforestry systems tend to maintain higher levels of biodiversity and greater biomass than lower diversity crop or pasture systems. Greater plant diversity may also enhance soil quality, further supporting agricultural productivity in nutrient-limited tropical systems. We studied the relationships between plant diversity (including species richness, phylogenetic diversity, and natural resource diversity), and soil quality within pasture, agroforest, and secondary forest: three common land use types maintained by small-scale farmers in the Pearl Lagoon Basin, Nicaragua. The area is undergoing accelerated globalization following the 2007 completion of the region's first major road; a change which is expected to increase forest conversion for agriculture. However, farmer agrobiodiversity maintenance in the Basin was previously found to be positively correlated with affiliation to local agricultural NGOs through the maintenance of agroforestry systems, despite these farmers residing in the communities closest to the new road, highlighting the potential for maintaining diverse agroforestry agricultural strategies despite heightened globalization pressures. We found that agroforestry sites tended to have higher surface soil %C, %N, and pH relative to neighboring to secondary forest, while maintaining comparable plant diversity. In contrast, pasture reduced species richness, phylogenetic diversity, and natural resource diversity. No significant relationships were found between plant diversity and the soil properties assessed; however higher species richness and phylodiversity was positively correlated with natural resource

Objective (1) Determine the incidence and risk factors for congenital hearing loss. (2) Perform cost analysis of screening programs. Study Design Proportionally distributed cross-sectional survey. Setting Jinotega, Nicaragua. Subjects and Methods Otoacoustic emissions (OAEs) were used to screen 640 infants <6 months of age from neonatal intensive care unit, institutional, and home birth settings. Data on 15 risk factors were analyzed. Cost of 4 implementation strategies was studied: universal screening, screening at the regional health center (RHC), targeted screening, and screening at the RHC plus targeted screening. Cost-effectiveness analysis over 10 years was based on disability-adjusted life year estimates, with the World Health Organization standard of cost-effectiveness ratio (CER) / gross domestic product (GDP) <3, with GDP set at $4884.15. Results Thirty-eight infants failed the initial OAE (5.94%). In terms of births, 325 (50.8%) were in the RHC, 69 (10.8%) in the neonatal intensive care unit, and 29 (4.5%) at home. Family history and birth defect were significant in univariate analysis; birth defect was significant in multivariate analysis. Cost-effectiveness analysis demonstrated that OAE screening is cost-effective without treatment (CER/GDP = 0.06-2.00) and with treatment (CER/GDP = 0.58-2.52). Conclusions Our rate of OAE failures was comparable to those of developed countries and lower than hearing loss rates noted among Nicaraguan schoolchildren, suggesting acquired or progressive etiology in the latter. Birth defects and familial hearing loss correlated with OAE failure. OAE screening of infants is feasible and cost-effective in rural Nicaragua, although highly influenced by estimated hearing loss severity in identified infants and the high travel costs incurred in a targeted screening strategy.

A qualitative study on primary health care professionals’ perceptions of mental health, suicidal problems and help-seeking among young people in Nicaragua

2014-01-01

Background Mental health problems among young peoples are a growing public health issue around the world. In low- income countries health systems are characterized by lack of facilities, human resources and primary health care is rarely an integrated part of overall health care services. This study aims at exploring how primary health care professionals in Nicaragua perceive young people’s mental health problems, suicidal problems and help–seeking behaviour. Methods Twelve in-depth interviews were conducted with nurses and doctors working in primary health care services in León, Nicaragua. A qualitative research design was applied. Data was analysed using thematic analysis approach. Results This study revealed that doctors and nurses were reluctant to deal with young people presenting with suicidal problems at the primary health care. This was more likely to stem from feelings of incompetence rather than from negative attitudes. Other barriers in providing appropriate care to young people with mental health problems were identified such as lack of time, lack of privacy, lack of human resources, lack of trained professionals and difficulties in communicating with young people. The primary health care (PHC) professionals suggested different solutions to improve care for young people with suicidal problems. Conclusion PHC doctors and nurses in Nicaragua felt that providing skilled mental health services to young people was a priority for them but they also identified a number of barriers to be able to do so. They discussed ways to improve young people’s willingness to share sensitive issues with them and suggested ways to make PHC more appreciated by young people. PMID:24989871

Tropical forest conversion to pasture, which drives greenhouse gas emissions, soil degradation, and biodiversity loss, remains a pressing socio-ecological challenge. This problem has spurred increased interest in the potential of small-scale agroforestry systems to couple sustainable agriculture with biodiversity conservation, particularly in rapidly developing areas of the tropics. In addition to providing natural resources (i.e. food, medicine, lumber), agroforestry systems have the potential to maintain higher levels of biodiversity and greater biomass than lower diversity crop or pasture systems. Greater plant diversity may also enhance soil quality, further supporting agricultural productivity in nutrient-limited tropical systems. Yet, the nature of these relationships remains equivocal.

Investigating competing uses of unevenly distributed resources in Nicaragua applying the Climate, Land Use (Food), Energy and Water strategies framework

The distribution of resources in Nicaragua is not even, as it is the case in many countries in the world. However, in the particular case of water resources, commonly used by different sectors and essential to basic human activities, their availability differs along the main drainage basins and is often mismatched with sectoral demands. For example, the population is distributed unevenly, with 80% being located in water scarce areas of the Pacific and Central region of Nicaragua. Agricultural activities also take place in regions where water resources are vulnerable. The spatial distribution of water and energy resources, population and land use in Nicaragua allowed for the identification of three target regions for the analysis: the Pacific coast, the Dry Corridor zone, and the Atlantic region. Each of these zones has different challenges on which the CLEWs assessment focused on. Water sources in the Pacific coast are mostly groundwater, and uncertainty exists related to the long-term availability of such source. This is also the region where most of the sugarcane, an important source of revenue for Nicaragua, is produced. As sugarcane needs to be irrigated, this increases the pressure on water resources. The Dry Corridor is an arid stretch in Central America cyclically affected by droughts that have a severe impact on the households whose economy and subsistence depends on agriculture of grains and coffee beans. It is expected that climate change will exacerbate further the food security problem. When water is lacking, also population experiences limited access to water for drinking and cooking. In addition, two major hydropower plants are located in this zone. Water resources are available both from surface and groundwater sources, however, due to their intensive use and vulnerability to climate, their availability can affect severely different sectors, presenting risks to food, water and energy security. Hydropower potential is foreseen to be exploited in the

On Dec. 4, 2015, the Advanced Land Imager (ALI) on NASA's Earth Observing 1 (EO-1) spacecraft observed the new eruption. This image is created from infrared data, and shows the incandescent active vent at the summit of the volcano and lava flowing down the side of the volcano. These data are being examined by scientists to determine where lava will flow, allowing assessment of possible threats to local infrastructure. The EO-1 data were obtained at an altitude of 438 miles (705 kilometers) and at a resolution of 98 feet (30 meters) per pixel at different visible and infrared wavelengths. The ALI image is 23 miles (37 kilometers) wide. http://photojournal.jpl.nasa.gov/catalog/PIA20203

The Psychological Impact of First Burn Camp in Nicaragua.

PubMed

Tropez-Arceneaux, Lisa L; Castillo Alaniz, Arlen Tatiana; Lucia Icaza, Ivette; Alejandra Murillo, Evelyn

Asociacion Pro-Ninos Quemados de Nicaragua (APROQUEN) is a comprehensive burn center that provides a holistic and integrated approach to treating burns. APROQUEN has set the standards internationally with acute treatment for burns, intensive care, reconstructive surgeries, nutritional care, rehabilitation, occupational therapy, and psychological treatment. APROQUEN is excelling within Central and South America with life-saving techniques and quality of care. It is imperative that burn centers in Central America recognize that the treatment of a child with a burn injury surpasses physical care to include psychological treatment for the complete well-being of the child. It is necessary to provide the tools necessary to reintegrate the child back into their environment. APROQUEN developed and implemented the first burn camp in Latin America, "Confio en Mi" (I trust myself). The camp theme focused on self-esteem. The camp program included theory (educational) and practice (applied) components where the campers through "classroom type" activities had the opportunity to reflect and share with other campers and camp staff on self-esteem, depression, and anxiety. Participants were children who survived major burns (N = 33; 58% women; ages 12-25; 61% <18) and were shown to have difficulty socializing. Comprehensive interviews were conducted to ensure fit for camp. Forty-two percent of the campers had not slept away from home since the burn injury. Mean TBSA = 20% and mean age at time of burn injury was 13. The majority of campers (46%) endured flame burn injuries, with 24% having scald injuries. Mean years postburn = 4.8 + 3.2. Most campers (40%) were enrolled in secondary school, 30% in elementary school, and 21% in college. Standardized measures (CDI-2 Parent Form and Child Form, Rosenberg Scale, APROQUEN Burn Camp Measure Parent and Child Form, Beck Anxiety Inventory, and Beck Depression Inventory) were given to all campers prior to attending camp.

Telica volcano, an andesitic stratovolcano in north-western Nicaragua, erupted in May 2011. The eruption, produced ash but no lava and required the evacuation of over 500 people; no injuries were reported. We present the first detailed report of the eruption, using information from the TElica Seismic ANd Deformation (TESAND) network, that provides real-time data, along with visual observations, ash leachate analysis, and fumarole temperature measurements. Telica is located in the Maribios mountain range. It is one of the most active volcanoes in Nicaragua and has frequent small explosions and rare large (VEI 4) eruptions, with the most recent sizable eruptions (VEI 2) occurring in 1946 and 1999. The 2011 eruption is the most explosive since 1999. The eruption consisted of a series of ash explosions, with the first observations from May 8, 2011 when local residents reported ash fall NE of the active crater. Popping sounds could be heard coming from the crater on May 10. On May 13, the activity intensified and continued with some explosions every day for about 2 weeks. The well-defined plumes originated from the northern part of the crater. Ash fall was reported 4 km north of the active crater on May 14. The largest explosion at 2:54 pm (local time) on May 21 threw rocks from the crater and generated a column 2 km in height. Fresh ash samples were collected on May 16, 18, and 21 and preliminary inspection shows that the majority of the material is fragmented rock and crystalline material, i.e. not juvenile. Ash leachates (ash:water = 1:25) contain a few ppb As, Se, and Cd; tens of ppb Co and Ni; and up to a few hundred ppb Cu and Zn. Telica typically has hundreds of small seismic events every day, even when the volcano is not erupting. The TESAND network detected an increase in the rate and magnitude of seismic activity, with a maximum magnitude of 3.3. Elevated fumarole temperatures at locations near the active vent were also observed throughout the May 2011

Background In Nicaragua, cervical cancer is the leading cause of cancer-related death for women ages 15–44, yet access to the HPV vaccine is limited to those with financial resources to pay for it. Cervical cytology is provided free of charge in public clinics; however, only 10% of women receive Pap smears at the nationally recommended frequency. Previous studies have not investigated how beliefs regarding cervical cancer screening may differ for urban and rural populations in Nicaragua. Furthermore, no investigation has assessed Nicaraguan women’s beliefs about a potential HPV immunization campaign. Given beliefs’ influence on health behavior, we investigated the structural, sociocultural, and knowledge-based factors influencing women’s beliefs regarding cervical cancer screening among urban and rural women in León, Nicaragua, and assessed acceptance of a potential HPV immunization program. Methods Our sequential explanatory mixed-methods study consisted of two phases: (1) a close-ended questionnaire, followed by (2) a qualitative, in-depth interview. Our quantitative sample contained 117 urban and 112 rural participants aged 18–49. We assessed beliefs regarding cervical cancer screening using a 22-item scale, with higher scores indicating screening-promoting beliefs in simple linear and multiple linear regressions. Twenty qualitative interviews, exploring the sociocultural dimensions of knowledge and attitudes indicated by our quantitative findings, were conducted with a sample of 13 urban and 7 rural women aged 19–46. Results The multiple linear regression indicates that greater knowledge of Pap smears, HPV, and cervical cancer is significantly associated with screening-promoting beliefs after adjusting for other relevant factors. There was no significant difference in screening knowledge and beliefs for urban and rural women.

Magma-Tectonic Interactions along the Central America Volcanic Arc: Insights from the August 1999 Magmatic and Tectonic Event at Cerro Negro, Nicaragua

Volcanic vent alignments form parallel to the direction of maximum horizontal stress, accommodating extensional strain via dike injection. Roughly east-west extension within the Central America Volcanic Arc is accommodated along north-northwest-trending basaltic vent alignments. In Nicaragua, these alignments are located in a northwest-trending zone of dextral shear, with shear accommodated along northeast trending bookshelf faults. The recent eruption of Cerro Negro volcano, Nicaragua and Marabios Range seismic swarm revealed the interaction of these fault systems. A low energy (VEI 1), small volume (0.001 km3 DRE) eruption of highly crystalline basalt occurred at Cerro Negro volcano, Nicaragua, August 5-7, 1999. This eruption followed three tectonic earthquakes (each Mw 5.2) in the vicinity of Cerro Negro hours before the onset of eruptive activity. The temporal and spatial pattern of microseismicity and focal mechanisms of the Mw 5.2 earthquakes suggests the activation of northeast-trending faults northwest and southeast of Cerro Negro within the Marabios Range. The eruption was confined to three new vents formed on the southern flank of Cerro Negro along a preexisting north-northwest trending alignment; the El Hoyo alignment of cinder cones, maars and explosion craters. Surface ruptures formed > 1 km south and southeast of the new vents suggest dike injection. Numerical simulations of conduit flow illustrate that the observed effusion rates (up to 65 ms-1) and fountain heights (50-300 m) can be achieved by eruption of magma with little or no excess fluid pressure, in response to tectonic strain. These observations and models suggest that 1999 Cerro Negro activity is an excellent example of tectonically induced small-volume eruptions in an arc setting.

Background An epidemic of chronic kidney disease (CKD) of non-traditional aetiology has been recently recognized by health authorities as a public health priority in Central America. Previous studies have identified strenuous manual work, agricultural activities and residence at low altitude as potential risk factors; however, the aetiology remains unknown. Because individuals are frequently diagnosed with CKD in early adulthood, we measured biomarkers of kidney injury among adolescents in different regions of Nicaragua to assess whether kidney damage might be initiated during childhood. Methods Participants include 200 adolescents aged 12–18 years with no prior work history from four different schools in Nicaragua. The location of the school served as a proxy for environmental exposures and geographic locations were selected to represent a range of factors that have been associated with CKD in adults (e.g. altitude, primary industry and CKD mortality rates). Questionnaires, urine dipsticks and kidney injury biomarkers [interleukin-18, N-acetyl-d-glucosaminidase (NAG), neutrophil gelatinase-associated lipocalin (NGAL) and albumin–creatinine ratio] were assessed. Biomarker concentrations were compared by school using linear regression models. Results Protein (3.5%) and glucose (1%) in urine measured by dipstick were rare and did not differ by school. Urine biomarkers of tubular kidney damage, particularly NGAL and NAG, showed higher concentrations in those schools and regions within Nicaragua that were defined a priori as having increased CKD risk. Painful urination was a frequent self-reported symptom. Conclusions Although interpretation of these urine biomarkers is limited because of the lack of population reference values, results suggest the possibility of early kidney damage prior to occupational exposures in these adolescents.

Normal block faulting in the Airport Graben, Managua pull-apart rift, Nicaragua: gravity and magnetic constraints

NASA Astrophysics Data System (ADS)

Campos-Enriquez, J. O.; Zambrana Arias, X.; Keppie, D.; Ramón Márquez, V.

2012-12-01

Regional scale models have been proposed for the Nicaraguan depression: 1) parallel rifting of the depression (and volcanic front) due to roll back of the underlying subducted Cocos plate; 2) right-lateral strike-slip faulting parallel to the depression and locally offset by pull-apart basins; 3) right-lateral strike-slip faulting parallel to the depression and offset by left-lateral transverse or bookshelf faults. At an intermediate scale, Funk et al. (2011) interpret the depression as half graben type structures. The E-W Airport graben lies in the southeastern part of the Managua graben (Nicaragua), across which the active Central American volcanic arc is dextrally offset, possibly the result of a subducted transform fault where the subduction angle changes. The Managua graben lies within the late Quaternary Nicaragua depression produced by backarc rifting during roll back of the Middle American Trench. The Managua graben formed as a pull-apart rift associated with dextral bookshelf faulting during dextral shear between the forearc and arc and is the locus of two historical, large earthquakes that destroyed the city of Managua. In order to asses future earthquake risk, four E-W gravity and magnetic profiles were undertaken to determine its structure across the Airport graben, which is bounded by the Cofradia and Airport fault zones, to the east and west, respectively. These data indicated the presence of a series of normal faults bounding down-thrown and up-thrown fault blocks and a listric normal fault, Sabana Grande Fault. The models imply that this area has been subjected to tectonic extension. These faults appear to be part of the bookshelf suite and will probably be the locus of future earthquakes, which could destroy the airport and surrounding part of Managua. Three regional SW-NE gravity profiles running from the Pacific Ocean up to the Caribbean See indicate a change in crustal structure: from north to south the crust thins. According to these regional

Because >60 rotavirus strains have been reported worldwide, concerns exist about strain replacement after the introduction of rotavirus vaccines, particularly in developing countries with diverse strains and lower efficacy. We used the case-control design in 4 hospitals in Nicaragua to assess strain-specific vaccine effectiveness (VE) of a pentavalent rotavirus vaccine (RotaTeq) against rotavirus diarrhea. Cases were identified through prospective strain surveillance with reverse transcription-polymerase chain reaction for 3 years among children hospitalized for diarrhea, and controls were children negative for rotavirus. We enrolled 1178 case-patients, 1082 (92%) with G and P typing, and 4927 controls. A different strain predominated each year with increasing age of the vaccine-eligible cohort during the study period: G2P[4] in 2008 (97%; mean age, 11.9 months), G1P[8] in 2009 (55%; mean age, 17.0 months), and G3P[8] in 2010 (78%; mean age, 17.3 months). Overall VE was 45% (95% confidence interval, 25%-59%). Regardless of the strain, VE estimates were 12%-79% lower among children aged ≥12 months relative to those 6-11 months of age. The lower VE for G3P[8] was related to the higher mean age of cases (17.3 months) compared with the G2P[4] strains (11.9 months), with a significant trend (R(2)= 0.819;P< .001) of declining effectiveness with increasing mean age of the cases. Introduction of RotaTeq did not result in sustained emergence of any particular strain in Nicaragua. Variation in strain-specific effectiveness was due to an age-related decline in effectiveness rather than differences in protection against the observed strains.

Background Nicaragua was the first developing nation to implement routine immunization with the pentavalent rotavirus vaccine (RV5). In this RV5-immunized population, understanding infectious etiologies of childhood diarrhea is necessary to direct diarrhea treatment and prevention efforts. Methods We followed a population-based sample of children less than 5 years in León, Nicaragua for diarrhea episodes through household visits. Information was obtained on RV5 history and sociodemographics. Stool samples collected during diarrhea episodes and among healthy children underwent laboratory analysis for viral, bacterial, and parasitic enteropathogens. Detection frequency and incidence of each enteropathogen was calculated. Results The 826 children in the cohort experienced 677 diarrhea episodes during 607.5 child-years of exposure time (1.1 episodes per child-year). At least one enteropathogen was detected among 61.1% of the 337 diarrheal stools collected. The most common enteropathogens among diarrheal stools were: norovirus (20.4%), sapovirus (16.6%), enteropathogenic Escherichia coli (EPEC, 11.3%), Entamoeba histolytica/dispar (8.3%), Giardia lamblia (8.0%), and enterotoxigenic E.coli (ETEC, 7.7%), with rotavirus detected among 5.3% of diarrheal stools. EPEC and ETEC were frequently detected among stools from healthy children. Among children with diarrhea, norovirus was more commonly detected among younger children (< 2 years) and G. lamblia was more commonly detected among older children (2-4 years). The mean age of rotavirus detection was 34.6 months. Conclusions In this Central American community following RV5 introduction, rotavirus was not commonly detected among children with diarrhea. Prevention and appropriate management of norovirus and sapovirus should be considered to further reduce the burden of diarrheal disease. PMID:24879131

Objectives To elicit the views of primary healthcare providers from Bolivia, Ecuador, and Nicaragua on how adolescent sexual and reproductive health (ASRH) care in their communities can be improved. Methods Overall, 126 healthcare providers (46 from Bolivia, 39 from Ecuador, and 41 from Nicaragua) took part in this qualitative study. During a series of moderated discussions, they provided written opinions about the accessibility and appropriateness of ASRH services and suggestions for its improvement. The data were analyzed by employing a content analysis methodology. Results Study participants emphasized managerial issues such as the prioritization of adolescents as a patient group and increased healthcare providers’ awareness about adolescent-friendly approaches. They noted that such an approach needs to be extended beyond primary healthcare centers. Schools, parents, and the community in general should be encouraged to integrate issues related to ASRH in the everyday life of adolescents and become ‘gate-openers’ to ASRH services. To ensure the success of such measures, action at the policy level would be required. For example, decision-makers could call for developing clinical guidelines for this population group and coordinate multisectoral efforts. Conclusions To improve ASRH services within primary healthcare institutions in three Latin American countries, primary healthcare providers call for focusing on improving the youth-friendliness of health settings. To facilitate this, they suggested engaging with key stakeholders, such as parents, schools, and decision-makers at the policy level. PMID:23680267

Psychometric properties of external HIV-related stigma and discrimination scales and their predictors were investigated. A cross-sectional community-based study was carried out among 520 participants using an ongoing health and demographic surveillance system in León, Nicaragua. Participants completed an 18-item HIV stigma scale and 19 HIV and AIDS discrimination-related statements. A factor analysis found that 15 of the 18 items in the stigma scale and 18 of the 19 items in the discrimination scale loaded clearly into five- and four-factor structures, respectively. Overall Cronbach's alpha of .81 for the HIV stigma scale and .91 for the HIV discrimination scale provided evidence of internal consistency. Hierarchical multiple linear regression analysis identified that females, rural residents, people with insufficient HIV-related transmission knowledge, those not tested for HIV, those reporting an elevated self-perception of HIV risk, and those unwilling to disclose their HIV status were associated with higher stigmatizing attitudes and higher discriminatory actions towards HIV-positive people. This is the first community-based study in Nicaragua that demonstrates that overall HIV stigma and discrimination scales were reliable and valid in a community-based sample comprised of men and women of reproductive age. Stigma and discrimination were reported high in the general population, especially among sub-groups. The findings in the current study suggest community-based strategies, including the monitoring of stigma and discrimination, and designing and implementing stigma reduction interventions, are greatly needed to reduce inequities and increase acceptance of persons with HIV.

This article analyses two instances of abortion law reform in Latin America. In 2006, after a decades-long impasse, the highly controversial issue of abortion came to dominate the political agenda when Colombia liberalized its abortion law and Nicaragua adopted a total ban on abortion. The article analyses the central actors in the reform processes, their strategies and the opportunity contexts. Drawing on Htun's (2003) framework, it examines why these processes concluded with opposing legislative outcomes. The authors argue for the need to understand the state as a non-unitary site of politics and policy, and for judicial processes to be seen as a key variable in facilitating gender policy reforms in Latin America. In addition, they argue that ‘windows of opportunity’ such as the timing of elections can be critically important in legislative change processes.

Using terrestrial radar to explore lava channel erosion on Momotombo volcano, Nicaragua

We explore the application of terrestrial radar as a tool for imaging topography on Momotombo volcano, Nicaragua. A major feature of the edifice is an incised lava flow channel (possibly created by the 1904 eruption) that measures 150m in width and up to 60m in depth. This feature is unusual because most lava channels are constructional in nature and constrained by levees on their margins. The radar elevation model was used alongside a TerraSAR-X/TanDEM-X DEM to help create a topographic time series. We consider the possibility that the channel was formed during the 1904 eruption by thermal and / or mechanical erosion. We aim to quantify the energy required to create the observed topography by merging this topographic time series with existing field observations and mathematical models of erosion via lava flow.

Geophysical Investigations of Magma Plumbing Systems at Cerro Negro Volcano, Nicaragua

NASA Astrophysics Data System (ADS)

MacQueen, Patricia Grace

Cerro Negro near Leon, Nicaragua is a very young (163 years), relatively small basaltic cinder cone volcano that has been unusually active during its short lifespan (recurrence interval 6--7 years), presenting a significant hazard to nearby communities. Previous studies have raised several questions as to the proper classification of Cerro Negro and its relation to neighboring Las Pilas-El Hoyo volcano. Analysis of Bouguer gravity data collected at Cerro Negro has revealed connected positive density anomalies beneath Cerro Negro and Las Pilas-El Hoyo. These findings suggest that eruptions at Cerro Negro may be tapping a large magma reservoir beneath Las Pilas-El Hoyo, implying that Cerro Negro should be considered the newest vent on the Las Pilas-El Hoyo volcanic complex. As such, it is possible that the intensity of volcanic hazards at Cerro Negro may eventually increase in the future to resemble those pertaining to a stratovolcano. Keywords: Cerro Negro; Las Pilas-El Hoyo; Bouguer gravity; magmatic plumbing systems; potential fields; volcano.

Leptospirosis is an epidemic-prone zoonotic disease that occurs worldwide, with more than 500,000 human cases reported annually. It is influenced by environmental and socioeconomic factors that affect the occurrence of outbreaks and the incidence of the disease. Critical areas and potential drivers for leptospirosis outbreaks have been identified in Nicaragua, where several conditions converge and create an appropriate scenario for the development of leptospirosis. The objectives of this study were to explore possible socioeconomic variables related to leptospirosis critical areas and to construct and validate a vulnerability index based on municipal socioeconomic indicators. Municipalities with lower socioeconomic status (greater unsatisfied basic needs for quality of the household and for sanitary services, and higher extreme poverty and illiteracy rates) were identified with the highest leptospirosis rates. The municipalities with highest local vulnerability index should be the priority for intervention. A distinction between risk given by environmental factors and vulnerability to risk given by socioeconomic conditions was shown as important, which also applies to the “causes of outbreaks” and “causes of cases”.

The social relations of health care and household resource allocation in neoliberal Nicaragua.

2010-05-22

With the transition to neoliberalism, Nicaragua's once-critically acclaimed health care services have substantially diminished. Local level social formations have been under pressure to try to bridge gaps as the state's role in the provision of health care and other vital social services has decreased. This paper presents a case study of how global and national health policies reverberated in the social relations of an extended network of female kin in a rural community during late 2002 - 2003. The qualitative methods used in this ethnographic study included semi-structured interviews completed during bi-weekly visits to 51 households, background interviews with 20 lay and professional health practitioners working in the public and private sectors, and participant-observation conducted in the region's government health centers. Interviews and observational field notes were manually coded and iteratively reviewed to identify and conceptually organize emergent themes. Three households of extended kin were selected from the larger sample to examine as a case study. The ongoing erosion of vital services formerly provided by the public sector generated considerable frustration and tension among households, networks of extended kin, and neighbors. As resource allocations for health care seeking and other needs were negotiated within and across households, longstanding ideals of reciprocal exchange persisted, but in conditions of poverty, expectations were often unfulfilled, exposing the tension between the need for social support, versus the increasingly oppositional positioning of social network members as sources of competition for limited resources. In compliance with neoliberal structural adjustment policies mandated by multilateral and bilateral agencies, government-provided health care services have been severely restricted in Nicaragua. As the national safety net for health care has been eroded, the viability of local level social formations and their ability to

Under the rubrics of preventive and social medicine, public health, and family and community medicine, medical educators in Latin America have developed programs to train physicians for community-oriented health care (COPC). The historical background for such programs in Latin America is reviewed. Three relevant examples of programs in Mexico, Nicaragua, and Costa Rica are highlighted, drawing on the author's direct experience with and in these faculties. The paper addresses the relation between these programs and national and regional trends in education and services. PMID:3826469

Leptospirosis is one of the most extended zoonosis worldwide and humans become infected most commonly through contact with the urine of carrier animals, either directly or via contaminated water or soil. The aim in this study was to analyse the epidemiological behaviour of Leptospira spp., from domestic animals around the sites of human leptospirosis cases in Nicaragua, from 2007 through 2013. We report the results of a cross-sectional epidemiological study with a non-probability sampling of blood (n=3050) and urine (n=299) from Domestic Animals (DA) around the sites of human leptospirosis cases in Nicaragua. We analysed data obtained through Microscopic Agglutination Test (MAT), in-vitro culture, real time PCR and sequencing of lfb1 locus. Frequencies of 30.31% (95% CI: 28.66-31.95) and 15.38% (95% CI: 11.12-19.64) were obtained from serological test and from in-vitro culture, respectively. Although similar frequencies from serology test (P≥0.05) were found in DA species, in-vitro culture frequencies were significantly higher from bovine, equine and sheep (P<0.05) in comparison with swine and canine species. Ten serogroups of pathogenic Leptospira spp. were encountered, with the highest presence of Icterohaemorrhagiae serogroup 34.65% (95% CI: 29.35-39.94). We identified 7 samples homologous to L. interrogans species Pyrogenes serovar and 3 samples as L. noguchii Louisiana or Panama serovars by analysis of lfb1 sequences. We were able to establish a temporal and spatial correlation from DA and cumulative incidence of human cases. Therefore an effective epidemiological surveillance should be implemented with a specific control program toward DA in order to reduce human leptospirosis incidence. Copyright © 2017 Elsevier B.V.

OBJECTIVE: To investigate the impact of violence against mothers on mortality risks for their offspring before 5 years of age in Nicaragua. METHODS: From a demographic database covering a random sample of urban and rural households in Le n, Nicaragua, we identified all live births among women aged 15-49 years. Cases were defined as those who had died before the age of 5 years, between January 1993 and June 1996. For each case, two referents, matched for sex and age at death, were selected from the database. A total of 110 mothers of the cases and 203 mothers of the referents were interviewed using a standard questionnaire covering mothers' experience of physical and sexual violence. The data were analysed for the risk associated with maternal experience of violence of infant and under-5 mortality. FINDINGS: A total of 61% of mothers of cases had a lifetime experience of physical and/or sexual violence compared with 37% of mothers of referents, with a significant association being found between such experiences and mortality among their offspring. Other factors associated with higher infant and under-5 mortality were mother's education (no formal education), age (older), and parity (multiparity). CONCLUSIONS: The results suggest an association between physical and sexual violence against mothers, either before or during pregnancy, and an increased risk of under-5 mortality of their offspring. The type and severity of violence was probably more relevant to the risk than the timing, and violence may impact child health through maternal stress or care-giving behaviours rather than through direct trauma itself.

A pilot-scale study was undertaken to evaluate alternatives to the solid waste management of a Central American municipal market located in Estelí, Nicaragua. The municipal solid waste from the local market is the second largest contributor to the municipal solid waste (MSW) stream. Waste from the market without any previous sorting or treatment is open dumped. The options evaluated in this study were windrow composting, windrow composting with yard waste, bokashi and vermicompost. Significant differences between the properties of composts produced were found; however, all of them reduce the initial waste volume and are potential useful agronomic products for a survival agrarian milieu.

Suitability of soil bioengineering techniques in Central America: a case study in Nicaragua

In the last few years "D. I. A. F." (Department of Agriculture and Forestry Engineering of Florence University), has been testing the effectiveness of Soil Bio-Engineering techniques in Central America. The focus of the present study was to find out which native plants were most suited for soil bio-engineering purposes, particularly in the realization of riverbank protection. Furthermore, we have also been aiming at economic efficiency. In the context of sustainable watershed management, these techniques seem to be appropriate, especially in underdeveloped countries. Concerning the plants to be used, we considered three native species, Gliricidia Sepium, Cordia dentata and Jatropha curcas, to be appropriate for this type of work. Economically speaking, the low cost of such interventions in underdeveloped countries, has been shown by the construction of riverbank protection using vegetated crib-walls in Nicaragua.

Quaternary volcanic rocks from the Central American Volcanic Arc in central Nicaragua and central Costa Rica exhibit major differences in their volatile, trace element and isotopic compositions. Olivine-hosted melt inclusions in Nicaraguan volcanic rocks with high Fo contents (>73) extend to high H2O (up to 5.3%), S (10-6860 ppm) and Cl (490-2340 ppm) contents. The volcanic rocks have high ratios of fluid mobile to fluid immobile elements such as Ba/La (65-122), Ba/Th (484-1304) and U/La (0.08-0.17). Additionally, they have 143Nd/144Nd (0.51300-0.51307) similar to normal mid-ocean-ridge basalts (N-MORB) from the East Pacific Rise (EPR), but 87Sr/86Sr (0.7035-0.7042) ratios are much higher than those found in fresh EPR glasses. Pb isotopic compositions of the samples (e.g. 206Pb/204Pb = 18.5-19.0, 207Pb/204Pb = 15.52-15.58) form an array between EPR basalts and subducted sediments. The volatile, trace element and isotope data are consistent with mixing of fluids highly enriched in fluid-mobile elements from subducted sediments with a N-MORB-type mantle wedge to produce the Nicaraguan volcanic rocks. In contrast, olivine-hosted melt inclusions (Fo >82) in Costa Rican volcanic rocks show a similar range in H2O (up to 5.1%) to Nicaraguan inclusions but overall have lower S (0-1340 ppm) and Cl (10-790 ppm) contents. Costa Rican lavas also have lower Ba/La (7-35), Ba/Th (55-338), U/La (0.02-0.12), 87Sr/86Sr (0.7035-0.7038) and 143Nd/144Nd (0.51292-0.51301) than Nicaraguan lavas, but 87Sr/86Sr and Pb isotope ratios (e.g. 206Pb/204Pb = 19.02-19.32) are more radiogenic than in Nicaragua and than usually found in fresh EPR MORB. Our data are consistent with the presence of Galapagos Hotspot-type components in the source of the central Costa Rican volcanic rocks, derived from the subducting Galapagos Hotspot Track and from Galapagos-type material entering the mantle wedge through a slab tear or window (Abratis and Worner, 2000; Geology).

The global carbon emissions budget over the next decades depends critically on the choices made by fast-growing emerging economies. Few studies exist, however, that develop country-specific energy system integration insights that can inform emerging economies in this decision-making process. High spatial- and temporal-resolution power system planning is central to evaluating decarbonization scenarios, but obtaining the required data and models can be cost prohibitive, especially for researchers in low, lower-middle income economies. Here, we use Nicaragua as a case study to highlight the importance of high-resolution open access data and modeling platforms to evaluate fuel-switching strategies and their resulting cost of power under realistic technology, policy, and cost scenarios (2014-2030). Our results suggest that Nicaragua could cost-effectively achieve a low-carbon grid (≥80%, based on non-large hydro renewable energy generation) by 2030 while also pursuing multiple development objectives. Regional cooperation (balancing) enables the highest wind and solar generation (18% and 3% by 2030, respectively), at the least cost (US127 MWh-1). Potentially risky resources (geothermal and hydropower) raise system costs but do not significantly hinder decarbonization. Oil price sensitivity scenarios suggest renewable energy to be a more cost-effective long-term investment than fuel oil, even under the assumption of prevailing cheap oil prices. Nicaragua’s options illustrate the opportunities and challenges of power system decarbonization for emerging economies, and the key role that open access data and modeling platforms can play in helping develop low-carbon transition pathways.

Irritable bowel syndrome (IBS) is a disabling functional gastrointestinal disorder, which serves as a model for abdominal pain syndromes. An association between intimate partner violence and IBS has been shown among Caucasian women in the industrialized world. To determine whether this relationship transcends cultural boundaries, we conducted a population-based, cross-sectional survey in Nicaragua, using the innovative Health and Demographic Surveillance System in the León province. Women who had experienced physical intimate partner violence had significantly increased risk of IBS (OR 2.08, 95% CI, 1.35, 3.21), as did those who had experienced sexual intimate partner violence (OR 2.85, 95% CI 1.45, 5.59). These findings argue for intimate partner violence screening among Latina women with IBS. PMID:20558772

Adverse drug reactions (ADRs) to antiretroviral therapy (ART) are an important cause of hospitalization, treatment discontinuation, and regimen changes in both developed and developing countries. This study is the first to examine and understand ADRs in HIV-infected patients in Nicaragua. A retrospective descriptive study was conducted from May 2010 to March 2011, in a cohort of HIV-infected patients receiving ART at the largest public hospital in Managua, Nicaragua. Patients were identified based on ADRs reporting on a standardized antiretroviral pharmacotherapy form. Subsequently, chart reviews of these patients were performed in order to document the specific ADRs. Six hundred ninety-two patients on ART were included. The incidence of ADRs was 6.4% (95% confidence interval [CI] 4.5-8.2). Females demonstrated a higher incidence, that is, 10.2% (95% CI 5.3-15.1, P = .020). Patients treated with combinations of zidovudine (ZDV)/lamivudine (3TC) and emtricitabine (FTC)/tenofovir (TDF) had fewer ADRs (P < .01) than those using other combinations. Five patients were hospitalized or had a prolonged hospitalization secondary to ADRs, with no mortality attributed to ADR. The most common manifestations of ADRs were central nervous system (20 of 44), gastrointestinal (12 of 44), and dermatologic (8 of 44) reactions. Adverse drug reactions were classified as "likely ADRs" (25 of 44) and "possible ADRs" (19 of 44). No ADRs were preventable. Adverse drug reactions most frequently affected the central nervous system. No ADR was life threatening. The frequency of ADRs in this Nicaraguan patient population was less than that reported from other studies in resource-limited settings. © The Author(s) 2014.

East German medical aid to Nicaragua: the politics of solidarity between biomedicine and primary health care.

Borowy, Iris

2017-01-01

Between 1979 and 1989 the government of the German Democratic Republic provided health assistance to Sandinista Nicaragua. After initial relief aid, the Sandinista embrace of a primary health care-based health system made East German health support difficult. The non-convertible currency, the repressive quality of the East German leadership, and the lack of experience with primary health care processes all limited its potential to provide support. After 1985, when implementation of this system stalled, East German health assistance was revitalized with the donation of the Hospital Carlos Marx. Providing medical services to three hundred thousand people, it combined elements of a strictly East German institution, using German personnel and equipment, with some integration into local systems.

The prevalence of soil-transmitted helminthiasis is close to half the population in Central America, with the marginalized peri-urban poor disproportionately affected. Previous single province helminth surveys conducted in Nicaragua have shown Ascaris lumbricoides to be the predominant species. In 2005, we conducted a cross-sectional study of 880 children in 10 Nicaraguan primary schools located in four provinces. We aimed to establish the prevalence and intensity of soil-transmitted helminth infections and to investigate the factors associated with helminthiasis. Almost half (46%) of the children were infected with soil-transmitted helminths. Tichuris trichiura was the most common infective species (34.7%). The prevalence and intensity of helminthiasis was heterogeneous in the provinces, with children educated in peri-urban schools most affected. Healthy policies are required that favour the peri-urban poor who have inadequate and declining access to water and sanitation.

MPA in Labor: Securing the Pearl Cays of Nicaragua

Implementation of Marine Protected Areas (MPAs) has always a step-zero, i.e., an initial phase when the idea is incepted, communicated and negotiated among stakeholders. What happens during this phase is likely to have an impact later on. If not done right, the management of the MPA may encounter problems at later stage that will be difficult to correct. Inspired by this working theory, this article describes the effort to establish the Pearl Cays off the Caribbean coast of Nicaragua as a protected area. This case-study illustrates the critical actions to be taken during step-zero, i.e., what needs to be considered and done before an MPA is formally declared. The area investigated consists of a number of small islands (cays) and coral reefs, fishing grounds and marine turtle nesting areas. Throughout history, the cays have played an important role in sustaining livelihoods of nearby communities. Although the idea of an MPA was originally conservation, the communities saw it as an opportunity to regain ownership and control of the cays. By Nicaraguan law, in order to establish protected areas, consultation and approval from local people is required. In the case of the Pearl Cays, this has proved difficult. The article demonstrates how MPA initiatives must sometimes relate to already ongoing complex social processes in the area where they are to be instigated.

In this case study from Nicaragua, an account is given of how the Essential Drugs Program developed in a context which relectss exceptional political, economic and military pressures. The overall picture could provide a useful guide to the issues behind such an apparently simple concept as the essential drugs list. The criteria for including drugs in the National Formulary were those of the WHO report on essential drugs: proven efficacy, acceptable risks associated with their use, favorable cost, and need. A proposal of the basic list of drugs, classified in therapeutic groups and according to their priority and level of use, was prepared by a central Committee for the National Drug Formulary. An annotated Formulary was prepared to ensure consistency with rigorous scientific standards and to meet the needs of daily practice. The annotated therapeutic formulary has been distributed to all physicians, other health workers responsible for peripheral health centers, pharmacists, and medical students. It has been adopted as the main reference textbook for teaching clinical pharmacology and therapeutics to medical students. A training program in clinical pharmacology has been started at the University Autonoma de Barcelona. It pays particular attention to drug evaluation, drug epidemiology methods, and retrieval and preparation of drug information for health workers.

In a post-war frontier area in north-western Nicaragua that was severely hit by Hurricane Mitch in 1998, local stakeholders embarked on and facilitated multi-dimensional development initiatives to break the cycles of poverty. The aim of this paper is to describe the process of priority-setting, and the strategies, guiding principles, activities, achievements, and lessons learned in these local development efforts from 1990 to 2014 in the Cuatro Santos area, Nicaragua. Data were derived from project records and a Health and Demographic Surveillance System that was initiated in 2004. The area had 25,893 inhabitants living in 5,966 households in 2014. A participatory process with local stakeholders and community representatives resulted in a long-term strategic plan. Guiding principles were local ownership, political reconciliation, consensus decision-making, social and gender equity, an environmental and public health perspective, and sustainability. Local data were used in workshops with communities to re-prioritise and formulate new goals. The interventions included water and sanitation, house construction, microcredits, environmental protection, school breakfasts, technical training, university scholarships, home gardening, breastfeeding promotion, and maternity waiting homes. During the last decade, the proportion of individuals living in poverty was reduced from 79 to 47%. Primary school enrolment increased from 70 to 98% after the start of the school breakfast program. Under-five mortality was around 50 per 1,000 live births in 1990 and again peaked after Hurricane Mitch and was approaching 20 per 1,000 in 2014. Several of the interventions have been scaled up as national programs. The lessons learned from the Cuatro Santos initiative underline the importance of a bottom-up approach and local ownership of the development process, the value of local data for monitoring and evaluation, and the need for multi-dimensional local interventions to break the cycles of

This study follows the social identity model of leadership proposed by van Knippenberg and Hogg (2003), in order to examine empirically the mediator effect of leadership prototypicality between social identity, extra effort, and perceived effectiveness of group members. The sample consisted of 109 participants who worked in 22 different work-teams of non-profit organizations (NPO) from Nicaragua and El Salvador. The data analysis was performed through structural equation modeling (SEM). The results show that NPO membership is related to a high level of social identity. In addition, the results confirmed that leadership prototypicality has a significant and positive mediator effect in the relationship between the group identification and the group members' extra effort and the perceived effectiveness of leadership.

This study offers a feminist psychology analysis of various aspects of relationship power and control and their relative explanatory contribution to understanding physical, psychological, and sexual violence against women. Findings from structured interviews with 345 women from rural Nicaragua (M age = 44) overwhelmingly demonstrate that measures of power and control reflecting interpersonal relationship dynamics have the strongest predictive power for explaining violence when compared in multivariate analyses to several of the more commonly used measures. These findings have implications for future research and the evaluation of interventions designed to decrease levels of violence against women. © The Author(s) 2014.

The reuse of treated wastewater for agricultural purposes in Nicaragua; Central America.

The first subsurface flow wetland (SSFW) system for about 1,000 PE, was constructed in Nicaragua in 1996 to apply this technology in the form of an integral project, combining the treatment of domestic wastewater with its reuse for crop production in small and medium size communities. The SSFW-effluent meets all standards established in the national regulations for wastewater reuse in agriculture, except for faecal coliforms, existent at an average concentration of 7 x 10(4) MPN/100 ml. A conventional surface irrigation method was used to irrigate different crop species selected to establish their risk of contamination. To judge the potential health risk for consumers and farmers, samples of vegetables and fruits harvested in the dry seasons of the years 1997 to 2002, were analyzed for the presence of pathogenic microorganisms like faecal coliforms, salmonella and shigella. In addition, a yield comparison between crops irrigated with well water using chemical fertilizers, and crops irrigated with the effluent of the SSFW-system was made, to analyze the economical benefits of the wastewater reuse.

In the Caribbean slope of Isthmian Central America, plant associations dominated by the palms Raphia taedigera and Manicaria saccifera develop in poorly drained or waterlogged soils. These associations are known locally as yolillales or palm-swamps, although there are differences in the forest structure and plant diversity associated with both palm species. In this paper, we report the results of a preliminary inventory of tree species found in eight palm-swamps at five locations in southeastern Nicaragua and northeastern Costa Rica. Our data reveal low tree diversity in these swamps with only 60 species accounted in them. This figure is equivalent to close to 8% of the plant species known for this region. In general, R. taedigera dominates flooded areas with extensive hydroperiods and lower floristic diversity, while M. saccifera is often found in flooded forests with more structure and diversity.

The Central American seasonally dry tropical (SDT) forest biome is one of the worlds' most endangered ecosystems, yet little is known about the genetic consequences of its recent fragmentation. A prominent constituent of this biome is Calycophyllum candidissimum, an insect-pollinated and wind-dispersed canopy tree of high socio-economic importance, particularly in Nicaragua. Here, we surveyed amplified fragment length polymorphisms across 13 populations of this species in Nicaragua to elucidate the relative roles of contemporary vs historical factors in shaping its genetic variation. Genetic diversity was low in all investigated populations (mean H E =0.125), and negatively correlated with latitude. Overall population differentiation was moderate (Φ ST =0.109, P<0.001), and Bayesian analysis of population structure revealed two major latitudinal clusters (I: 'Pacific North'+'Central Highland'; II: 'Pacific South'), along with a genetic cline between I and II. Population-based cluster analyses indicated a strong pattern of 'isolation by distance' as confirmed by Mantel's test. Our results suggest that (1) the low genetic diversity of these populations reflects biogeographic/population history (colonisation from South America, Pleistocene range contractions) rather than recent human impact; whereas (2) the underlying process of their isolation by distance pattern, which is best explained by 'isolation by dispersal limitation', implies contemporary gene flow between neighbouring populations as likely facilitated by the species' efficient seed dispersal capacity. Overall, these results underscore that even tree species from highly decimated forest regions may be genetically resilient to habitat fragmentation due to species-typical dispersal characteristics, the necessity of broad-scale measures for their conservation notwithstanding.

The sensory quality and the contents of quality-determining chemical compounds in unfermented and fermented cocoa from 100 cacao trees (individual genotypes) representing groups of nine genotype spectra (GG), grown at smallholder plantings in the municipality of Waslala, Nicaragua, were evaluated for two successive harvest periods. Cocoa samples were fermented using a technique mimicking recommended on-farm practices. The sensory cocoa quality was assessed by experienced tasters, and seven major chemical taste compounds were quantified by near infrared spectrometry (NIRS). The association of the nine, partially admixed, genotype spectra with the analytical and sensory quality parameters was tested. The individual parameters were analyzed as a function of the factors GG and harvest (including the date of fermentation), individual trees within a single GG were used as replications. In fermented cocoa, significant GG-specific differences were observed for methylxanthines, theobromine-to-caffeine (T/C) ratio, total fat, procyanidin B5 and epicatechin, as well as the sensory attributes global score, astringency, and dry fruit aroma, but differences related to harvest were also apparent. The potential cocoa yield was also highly determined by the individual GG, although there was significant tree-to-tree variation within every single GG. Non-fermented samples showed large harvest-to-harvest variation of their chemical composition, while differences between GG were insignificant. These results suggest that selection by the genetic background, represented here by groups of partially admixed genotype spectra, would be a useful strategy toward enhancing quality and yield of cocoa in Nicaragua. Selection by the GG within the local, genetically segregating populations of seed-propagated cacao, followed by clonal propagation of best-performing individuals of the selected GG could be a viable alternative to traditional propagation of cacao by seed from open pollination.

The potential cocoa yield was also highly determined by the individual GG, although there was significant tree-to-tree variation within every single GG. Non-fermented samples showed large harvest-to-harvest variation of their chemical composition, while differences between GG were insignificant. These results suggest that selection by the genetic background, represented here by groups of partially admixed genotype spectra, would be a useful strategy toward enhancing quality and yield of cocoa in Nicaragua. Selection by the GG within the local, genetically segregating populations of seed-propagated cacao, followed by clonal propagation of best-performing individuals of the selected GG could be a viable alternative to traditional propagation of cacao by seed from open pollination.

Horses, mules and donkeys are indispensable farming and working animals in many developing countries, and their health status is important to the farmers. Strongyle parasites are ubiquitous in grazing horses world-wide and are known to constitute a threat to equine health. This study determined the prevalence of strongyle infection, the efficacy of ivermectin and fenbendazole treatment, and strongyle re-infection rates of working horses during the dry months in Nicaragua. One hundred and five horses used by farmers for transport of people and goods were randomly allocated into three treatment groups, i.e., the IVM group treated with ivermectin, the FBZ group treated with fenbendazole and the control group treated with placebo. Determined by pre-treatment faecal egg counts (FECs), horses showed a high prevalence (94%) of strongyle parasites with high intensities of infection (mean FEC of 1117 eggs per gram (EPG) with an SD of 860 EPG, n=102). Body condition scores of all horses ranged from 1.5 to 3.5 with a mean of 2.4 (scales 1-5). Fourteen days after treatment faecal egg count reductions (FECRs) were 100% and 94% in the IVM and the FBZ groups, respectively. The egg reappearance period (ERP) defined as the time until the mean FEC reached 20% of the pre-treatment level, was estimated as 42 days for the FBZ group and 60 days for the IVM group. Individual faecal cultures were set up and the larval differentiation revealed a 36% prevalence of Strongylus vulgaris before treatment (n=45). In the FBZ group, 25% of the horses were S. vulgaris-positive 70 days post treatment compared to 11% in the IVM group. Our results indicate that strongyle infection intensities in Nicaragua are high and that S. vulgaris is endemic in the area. Furthermore, efficacies and ERPs of IVM and FBZ were within the expected range with no signs of anthelmintic resistance. Copyright © 2011 Elsevier B.V. All rights reserved.

To evaluate the associations of women's autonomy and social support with infant and young child feeding practices (including consumption of highly processed snacks and sugar-sweetened beverages) and nutritional status in rural Nicaragua. Cross-sectional study. Feeding practices and children's nutritional status were evaluated according to the WHO guidelines complemented with information on highly processed snacks and sugar-sweetened beverages. Women's autonomy was assessed by a seventeen-item questionnaire covering dimensions of financial independence, household-, child-, reproductive and health-related decision making and freedom of movement. Women's social support was determined using the Duke-UNC Functional Social Support Questionnaire. The scores attained were categorized into tertiles. Los Cuatro Santos area, rural Nicaragua. A total of 1371 children 0-35 months of age. Children of women with the lowest autonomy were more likely to be exclusively breast-fed and continue to be breast-fed, while children of women with middle level of autonomy had better complementary feeding practices. Children of women with the lowest social support were more likely to consume highly processed snacks and/or sugar-sweetened beverages but also be taller. While lower levels of autonomy and social support were independently associated with some favourable feeding and nutrition outcomes, this may not indicate a causal relationship but rather that these factors reflect other matters of importance for child care.

San Cristóbal volcano in northwest Nicaragua is one of the most active basaltic-andesitic stratovolcanoes of the Central American Volcanic Arc (CAVA). Here we provide novel constraints on the volcano's magmatic plumbing system, by presenting the first direct measurements of major volatile contents in mafic-to-intermediate glass inclusions from Holocene and historic-present volcanic activity. Olivine-hosted (forsterite [Fo] < 80; Fo< 80) glass inclusions from Holocene tephra layers contain moderate amounts of H2O (0.1-3.3 wt%) and S and Cl up to 2500 μg/g, and define the mafic (basaltic) endmember component. Historic-present scoriae and tephra layers exhibit more-evolved olivines (Fo69-72) that contain distinctly lower volatile contents (0.1-2.2 wt% H2O, 760-1675 μg/g S, and 1021-1970 μg/g Cl), and represent a more-evolved basaltic-andesitic magma. All glass inclusions are relatively poor in CO2, with contents reaching 527 μg/g (as measured by nanoscale secondary ion mass spectrometry), suggesting pre- to postentrapment CO2 loss to a magmatic vapor. We use results of Raman spectroscopy obtained in a population of small (< 50 μm) inclusions with CO2-bearing shrinkage bubbles (3-12 μm) to correct for postentrapment CO2 loss to bubbles, and to estimate the original minimum CO2 content in San Cristóbal parental melts at 1889 μg/g, which is consistent with the less-CO2-degassed melt inclusions (MI) (> 1500 μg/g) found in Nicaragua at Cerro Negro, Nejapa, and Granada. Models of H2O and CO2 solubilities constrain the degassing pathway of magmas up to 425 MPa ( 16 km depth), which includes a deep CO2 degassing step (only partially preserved in the MI record), followed by coupled degassing of H2O and S plus crystal fractionation at magma volatile saturation pressures from ∼ 195 to < 10 MPa. The variation in volatile contents from San Cristóbal MI is interpreted to reflect (1) Holocene eruptive cycles characterized by the rapid emplacement of basaltic magma

In Central America, few cases of leprosy have been reported, but the disease may be unrecognized. Diagnosis is based on clinical criteria and histology. Preliminary field work in Nicaragua and Honduras found patients, including many children, with skin lesions clinically suggestive of atypical cutaneous leishmaniasis or indeterminate leprosy. Histology could not distinguish these diseases although acid-fast organisms were visible in a few biopsies. Lesions healed after standard antimicrobial therapy for leprosy. In the present study, patients, family members, and other community members were skin-tested and provided nasal swabs and blood samples. Biopsies were taken from a subgroup of patients with clinical signs of infection. Two laboratories analyzed samples, using local in-house techniques. Mycobacterium leprae , Leishmania spp. and Leishmania infantum were detected using polymerase chain reactions. Mycobacterium leprae DNA was detected in blood samples and nasal swabs, including some cases where leprosy was not clinically suspected. Leishmania spp. were also detected in blood and nasal swabs. Most biopsies contained Leishmania DNA and coinfection of Leishmania spp. with M. leprae occurred in 33% of cases. Mycobacterium leprae DNA was also detected and sequenced from Nicaraguan and Honduran environmental samples. In conclusion, leprosy and leishmaniasis are present in both regions, and leprosy appears to be widespread. The nature of any relationship between these two pathogens and the epidemiology of these infections need to be elucidated.

Developments in health care in Nicaragua.

The 4 year war that resulted in the overthrow of Nicaragua's Somoza dictatorship cost 50,000 lives. In 1972 an earthquake killed 20,000 with 10,000 injured. Under Somoza health conditions had been worse than in neighboring countries with 35% of the urban and 95% of the rural population lacking access to potable water and only about 10% of the population receiving adequate medical care. 1/3 of the people contracted malaria at least once in their lives and 46-83% of the children were malnourished. Life expectancy at the time of the revolution was 52.9 years, infant mortality was between 120-140/1000. Since July 1979, however, about 70% of the people have regular medical care and health care education campaigns are widespread. Public health programs have administered vaccinations to thousands of children and literacy programs have incorporated elementary health principles into their curricula. However, despite these efforts malaria continued to rise from 4.4 people/1000 in 1978 to 9.4/1000 in 1980. After an antimalarial drug campaign in 1981, a 98% decline was noted in new cases of malaria. Poliomyelitis and tuberculosis prevention campaigns are likewise effective and oral rehydration centers have been set up to combat infant diarrhea. Having recently experienced a baby boom, a campaign to disseminate family planning information is being planned. Technical and professional health training has been expanded as well with a second medical school opening in Managua in 1981 along with growth in the amount of nursing school students. International aid has been crucial in health care with more than 24 countries sending medical supplies and personnel. Lack of equipment and facilities is holding back medical advances and there is a dilemma concerning physicians' time spent at public versus their private practices. Drugs remain the largest health import for the country even though their pharmaceutical manufacturers have increased production. 5 new hospitals are being built with

OBJECTIVES. The purpose of this study was to demonstrate the usefulness of the Northwestern Nicaraguan Ministry of Health surveillance system for detecting pesticide poisonings. METHODS. Cases were reported to the regional department of epidemiology through daily telephone reports and through monthly consolidated reports from each of the 18 health centers of the National Health Service. Reporting forms were also distributed to the four area hospitals. RESULTS. During June and July 1987, an epidemic of 548 pesticide poisoning was detected in northwestern Nicaragua. Seventy-seven percent of the poisonings were caused by carbofuran or methamidophos. Of the work-related cases (91% of reported poisonings), more than 80% occurred among maize farmers and on small to medium land holdings (fewer than 140 hectares). Nineteen percent of the work-related cases involved children under 16 years of age. CONCLUSIONS. Unsafe working conditions such as manual application of pesticides and the use of backpack sprayers, the introduction of a hazardous powdered formulation of carbofuran highly restricted in the developed world, and agricultural subsidies that encouraged the use of hazardous pesticides all contributed to the epidemic.

Lahar Hazards at Concepción volcano, Nicaragua

Concepción is one of Nicaragua’s highest and most active volcanoes. The symmetrical cone occupies the northeastern half of a dumbbell shaped island called Isla Ometepa. The dormant volcano, Maderas, occupies the southwest half of the island. A narrow isthmus connects Concepción and Maderas volcanoes. Concepción volcano towers more than 1600 m above Lake Nicaragua and is within 5 to 10 km of several small towns situated on its aprons at or near the shoreline. These towns have a combined population of nearly 5,000. The volcano has frequently produced debris flows (watery flows of mud, rock, and debris—also known as lahars when they occur on a volcano) that could inundate these nearby populated areas. Concepción volcano has erupted more than 25 times in the last 120 years. Its first recorded activity was in AD 1883. Eruptions in the past century, most of which have originated from a small summit crater, comprise moderate explosions, ash that falls out of eruption plumes (called tephra), and occasional lava flows. Near the summit area, there are accumulations of rock that were emplaced hot (pyroclastic deposits), most of which were hot enough to stick together during deposition (a process called welding). These pyroclastic rocks are rather weak, and tend to break apart easily. The loose volcanic rock remobilizes during heavy rain to form lahars. Volcanic explosions have produced blankets of tephra that are distributed downwind, which on Isla Ometepe is mostly to the west. Older deposits at the west end of the island that are up to 1 m thick indicate larger explosive events have happened at Concepción volcano in prehistoric time. Like pyroclastic-flow deposits, loose tephra on the steep slopes of the volcano provides source material that heavy rainstorms and earthquakes can mobilize to trigger debris flow.

Health care providers play a central role in the promotion and protection of human rights in patient care. Consequently, the World Medical Association, among others, has called on medical and nursing schools to incorporate human rights education into their training programs. This report describes the efforts of one Central American nongovernmental organization to include human rights - related content into reproductive health care provider training programs in Nicaragua and El Salvador. Baseline findings suggest that health care providers are not being adequately prepared to fulfill their duty to protect and promote human rights in patient care. Medical and nursing school administrators, faculty, and students recognize the need to strengthen training in this area and are enthusiastic about incorporating human rights content into their education programs. Evaluation findings suggest that exposure to educational materials and methodologies that emphasize the relationship between human rights and reproductive health may lead to changes in health care provider attitudes and behaviors that help promote and safeguard human rights in patient care.

The study of parallel evolution facilitates the discovery of common rules of diversification. Here, we examine the repeated evolution of thick lips in Midas cichlid fishes (the Amphilophus citrinellus species complex)-from two Great Lakes and two crater lakes in Nicaragua-to assess whether similar changes in ecology, phenotypic trophic traits and gene expression accompany parallel trait evolution. Using next-generation sequencing technology, we characterize transcriptome-wide differential gene expression in the lips of wild-caught sympatric thick- and thin-lipped cichlids from all four instances of repeated thick-lip evolution. Six genes (apolipoprotein D, myelin-associated glycoprotein precursor, four-and-a-half LIM domain protein 2, calpain-9, GTPase IMAP family member 8-like and one hypothetical protein) are significantly underexpressed in the thick-lipped morph across all four lakes. However, other aspects of lips' gene expression in sympatric morphs differ in a lake-specific pattern, including the magnitude of differentially expressed genes (97-510). Generally, fewer genes are differentially expressed among morphs in the younger crater lakes than in those from the older Great Lakes. Body shape, lower pharyngeal jaw size and shape, and stable isotopes (δ(13)C and δ(15)N) differ between all sympatric morphs, with the greatest differentiation in the Great Lake Nicaragua. Some ecological traits evolve in parallel (those related to foraging ecology; e.g. lip size, body and head shape) but others, somewhat surprisingly, do not (those related to diet and food processing; e.g. jaw size and shape, stable isotopes). Taken together, this case of parallelism among thick- and thin-lipped cichlids shows a mosaic pattern of parallel and nonparallel evolution. © 2012 Blackwell Publishing Ltd.

Livestock systems in the tropics can contribute to mitigate climate change by reducing greenhouse gas (GHG) emissions and increasing carbon accumulation. We quantified C stocks and GHG emissions of 30 dual-purpose cattle farms in Nicaragua using farm inventories and lifecycle analysis. Trees in silvo-pastoral systems were the main C stock above-ground (16-24 Mg ha-1), compared with adjacent secondary forests (43 Mg C ha-1). We estimated that methane from enteric fermentation contributed 1.6 kg CO2-eq., and nitrous oxide from excreta 0.4 kg CO2-eq. per kg of milk produced. Seven farms that we classified as climate-smart agriculture (CSA) out of 16 farms had highest milk yields (6.2 kg cow-1day-1) and lowest emissions (1.7 kg CO2-eq. per kg milk produced). Livestock on these farms had higher-quality diets, especially during the dry season, and manure was managed better. Increasing the numbers of CSA farms and improving CSA technology will require better enabling policy and incentives such as payments for ecosystem services.

2000-12-01

The aim of this study was to describe the characteristics of domestic violence against women in León, Nicaragua. A survey was carried out among a representative sample of 488 women between the ages of 15-49. The physical aggression sub-scale of the Conflict Tactics Scale was used to identify women suffering abuse. In-depth interviews with formerly battered women were performed and narratives from these interviews were analysed and compared with the survey data. Among ever-married women 52% reported having experienced physical partner abuse at some point in their lives. Median duration of abuse was 5 years. A considerable overlap was found between physical, emotional and sexual violence, with 21% of ever-married women reporting all three kinds of abuse. Thirty-one percent of abused women suffered physical violence during pregnancy. The latency period between the initiation of marriage or cohabitation and violence was short, with over 50% of the battered women reporting that the first act of violence act took place within the first 2 years of marriage. Significant, positive associations were found between partner abuse and problems among children, including physical abuse. Both the survey data and the narrative analysis pointed to extreme jealousy and control as constant features of the abusive relationship. Further, the data indicate that battered women frequently experience feelings of shame, isolation and entrapment which, together with a lack of family and community support, often contribute to women's difficulty in recognizing and disengaging from a violent relationship. These findings are consistent with theoretical conceptualisations of domestic violence developed in other countries, suggesting that, to a large degree, women's experiences of violence transcend specific cultural contexts.

ABSTRACT Background: In a post-war frontier area in north-western Nicaragua that was severely hit by Hurricane Mitch in 1998, local stakeholders embarked on and facilitated multi-dimensional development initiatives to break the cycles of poverty. Objective: The aim of this paper is to describe the process of priority-setting, and the strategies, guiding principles, activities, achievements, and lessons learned in these local development efforts from 1990 to 2014 in the Cuatro Santos area, Nicaragua. Methods: Data were derived from project records and a Health and Demographic Surveillance System that was initiated in 2004. The area had 25,893 inhabitants living in 5,966 households in 2014. Results: A participatory process with local stakeholders and community representatives resulted in a long-term strategic plan. Guiding principles were local ownership, political reconciliation, consensus decision-making, social and gender equity, an environmental and public health perspective, and sustainability. Local data were used in workshops with communities to re-prioritise and formulate new goals. The interventions included water and sanitation, house construction, microcredits, environmental protection, school breakfasts, technical training, university scholarships, home gardening, breastfeeding promotion, and maternity waiting homes. During the last decade, the proportion of individuals living in poverty was reduced from 79 to 47%. Primary school enrolment increased from 70 to 98% after the start of the school breakfast program. Under-five mortality was around 50 per 1,000 live births in 1990 and again peaked after Hurricane Mitch and was approaching 20 per 1,000 in 2014. Several of the interventions have been scaled up as national programs. Conclusions: The lessons learned from the Cuatro Santos initiative underline the importance of a bottom-up approach and local ownership of the development process, the value of local data for monitoring and evaluation, and the need

Feminist Organizing in Rural Nicaragua: Assessing a Psychosocial Process to Promote Empowered Solidarity.

This study examines a psychosocial process linking women's involvement in a grassroots women's organization with skills and experiences to promote empowered solidarity. Empowered solidarity is described as a process of increasing the sense of connection and capacity to create social transformation among a group of people united by interest in addressing a social issue. Data collected and analyzed for this research were 298 quantitative surveys conducted with two groups of women living in rural Nicaragua. One group of women were members of a grassroots feminist organization, and the other group lived in nearby communities where the organization did not offer programs. Findings document higher levels of leadership skills and sense of community, and lower levels of powerlessness among members of the organization. Additionally, tests of a process model using structural equation modeling provides support for a model that links involvement in the organization to women's increased interest in, capacity and experience in working to support women, broadly. Overall findings from this research are valuable to both community psychologists and groups seeking to enhance social justice and uphold feminist values of equity and community well-being. © Society for Community Research and Action 2018.

Chagas disease is one of the neglected tropical diseases (NTDs). International goals for its control involve elimination of vector-borne transmission. Central American countries face challenges in establishing sustainable vector control programmes, since the main vector, Triatoma dimidiata, cannot be eliminated. In 2012, the Ministry of Health in Nicaragua started a field test of a vector surveillance-response system to control domestic vector infestation. This paper reports the main findings from this pilot study. This study was carried out from 2012 to 2015 in the Municipality of Totogalpa. The Japan International Cooperation Agency provided technical cooperation in designing and monitoring the surveillance-response system until 2014. This system involved 1) vector reports by householders to health facilities, 2) data analysis and planning of responses at the municipal health centre and 3) house visits or insecticide spraying by health personnel as a response. We registered all vector reports and responses in a digital database. The collected data were used to describe and analyse the system performance in terms of amount of vector reports as well as rates and timeliness of responses. During the study period, T. dimidiata was reported 396 times. Spatiotemporal analysis identified some high-risk clusters. All houses reported to be infested were visited by health personnel in 2013 and this response rate dropped to 39% in 2015. Rates of insecticide spraying rose above 80% in 2013 but no spraying was carried out in the following 2 years. The timeliness of house visits improved significantly after the responsibility was transferred from a vector control technician to primary health care staff. We argue that the proposed vector surveillance-response system is workable within the resource-constrained health system in Nicaragua. Integration to the primary health care services was a key to improve the system performance. Continual efforts are necessary to keep adapting

Four social audits in 1998, 2003, 2006 and 2009 identified actions that Nicaragua could take to reduce corruption and public perception in primary health care and other key services. In a 71-cluster sample, weighted according to the 1995 census and stratified by geographic region and settlement type, we audited the same five public services: health centres and health posts, public primary schools, municipal government, transit police and the courts. Some 6,000 households answered questions about perception and personal experience of unofficial and involuntary payments, payments without obtaining receipts or to the wrong person, and payments "to facilitate" services in municipal offices or courts. Additional questions covered complaints about corruption and confidence in the country's anti-corruption struggle. Logistic regression analyses helped clarify local variations and explanatory variables. Feedback to participants and the services at both national and local levels followed each social audit. Users' experience of corruption in health services, education and municipal government decreased. The wider population's perception of corruption in these sectors decreased also, but not as quickly. Progress among traffic police faltered between 2006 and 2009 and public perception of police corruption ticked upwards in parallel with drivers' experience. Users' experience of corruption in the courts worsened over the study period--with the possible exception of Managua between 2006 and 2009--but public perception of judicial corruption, after peaking in 2003, declined from then on. Confidence in the anti-corruption struggle grew from 50% to 60% between 2003 and 2009. Never more than 8% of respondents registered complaints about corruption.Factors associated with public perception of corruption were: personal experience of corruption, quality of the service itself, and the perception that municipal government takes community opinion into account and keeps people informed

GPS-derived coupling estimates for the Central America subduction zone and volcanic arc faults: El Salvador, Honduras and Nicaragua

We invert GPS velocities from 32 sites in El Salvador, Honduras and Nicaragua to estimate the rate of long-term forearc motion and distributions of interseismic coupling across the Middle America subduction zone offshore from these countries and faults in the Salvadoran and Nicaraguan volcanic arcs. A 3-D finite element model is used to approximate the geometries of the subduction interface and strike-slip faults in the volcanic arc and determine the elastic response to coupling across these faults. The GPS velocities are best fit by a model in which the forearc moves 14-16 mmyr-1 and has coupling of 85-100 per cent across faults in the volcanic arc, in agreement with the high level of historic and recent earthquake activity in the volcanic arc. Our velocity inversion indicates that coupling across the potentially seismogenic areas of the subduction interface is remarkably weak, averaging no more than 3 per cent of the plate convergence rate and with only two poorly resolved patches where coupling might be higher along the 550-km-long segment we modelled. Our geodetic evidence for weak subduction coupling disagrees with a seismically derived coupling estimate of 60 +/- 10 per cent from a published analysis of earthquake damage back to 1690, but agrees with three other seismologic studies that infer weak subduction coupling from 20th century earthquakes. Most large historical earthquakes offshore from El Salvador and western Nicaragua may therefore have been intraslab normal faulting events similar to the Mw 7.3 1982 and Mw 7.7 2001 earthquakes offshore from El Salvador. Alternatively, the degree of coupling might vary with time. The evidence for weak coupling indirectly supports a recently published hypothesis that much of the Middle American forearc is escaping to the west or northwest away from the Cocos Ridge collision zone in Costa Rica. Such a hypothesis is particularly attractive for El Salvador, where there is little or no convergence obliquity to drive the

Globally about 40% of adults are diagnosed with hypertension, with high-income countries having a lower prevalence than low-income countries. However, there are limited data about adult hypertension prevalence in Nicaragua. The purpose of this study was to determine the prevalence of hypertension in rural coffee farm workers. A convenience sample of 229 adult coffee farm workers was used. Blood pressure was measured using an established protocol and the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC-7) guidelines. Nearly 60% of the sample reported at least one prior blood pressure measurement. Hypertension was detected in 16.7% of males and 26.3% of females (20.7% of the total). Prehypertension was detected in 59.3% of males and 27.7% of females (46.2% of the total). Of the men, 51.4% reported smoking at least some days and just over one third of the sample reported adding extra salt to their food. While the prevalence of hypertension in this sample is lower than global estimates, almost half of the sample had prehypertension, demonstrating an area where health promotion efforts could be focused. Given the limited funding and resources often available in these areas, increasing disease prevention efforts (including health promotion and wellness programs) and establishing settings that provide outreach and education, may improve chronic disease management and prevent comorbidities from occurring.

Our study aimed to evaluate the effect of various risk indicators for dental caries on primary teeth of Nicaraguan children (from Leon, Nicaragua) ages 6 to 9, using the negative binomial regression model. A cross-sectional study was carried out to collect clinical, demographic, socioeconomic, and behavioral data from 794 schoolchildren ages 6 to 9 years, randomly selected from 25 schools in the city of León, Nicaragua. Clinical examinations for dental caries (dmft index) were performed by 2 trained and standardized examiners. Socio-demographic, socioeconomic, and behavioral data were self-reported using questionnaires. Multivariate negative binomial regression (NBR) analysis was used. Mean age was 7.49 ± 1.12 years. Boys accounted for 50.1% of the sample. Mean dmft was 3.54 ± 3.13 and caries prevalence (dmft >0) was 77.6%. In the NBR multivariate model (p<0.05), for each year of age, the expected mean dmft decreased by 7.5%. Brushing teeth at least once a day and having received preventive dental care in the last year before data collection were associated with declines in the expected mean dmft by 19.5% and 69.6%, respectively. Presence of dental plaque increased the expected mean dmft by 395.5%. The proportion of students with caries in this sample was high. We found associations between dental caries in the primary dentition and dental plaque, brushing teeth at least once a day, and having received preventive dental care. To improve oral health, school programs and/or age-appropriate interventions need to be developed based on the specific profile of caries experience and the associated risk indicators.

Previous studies of subduction zone earthquakes have shown that fault conditions control earthquake rupture and behavior. There are many potential properties that may vary along the subduction margin that could cause fault zone variability, including plate age, temperature, and/or geometry, convergence rate, state of hydration, overriding geology, subducting sediment packages, or subducting seamounts/ridges. The Nicaragua/Costa Rica segment of the Middle America subduction zone is highly variable along strike and down dip. We use this margin to examine how these variable conditions affect earthquake behavior by determining local ratios of compressional to shear wave velocities (Vp/Vs) and detailed seismic velocity structure. Vp/Vs is one of the best tools available to reliably define fault conditions because it is directly related to the Poisson's ratio of the fault material, and it is sensitive to the presence of fluids and changing permeability. Thus with well-resolved near source Vp/Vs measurements we can infer composition and/or high fluid pressures. Here, we use a technique developed by Lin and Shearer (2007) to determine local Vp/Vs in small areas (~2 x 2 x 2 km) with high seismicity. Within the seismogenic zone, we find the margin to be highly variable along strike in Vp/Vs and seismic velocity. These changes correlate to documented variability in incoming plate properties. Increased Vp/Vs is associated with intraplate earthquakes along Nicaragua and northern Costa Rica. We compare our results with other geophysical studies including new high-resolution images of seismic velocity structure, an extensive catalog of high quality relocated events, apparent stress calculations, coupling, and SSE/NVT occurrence. A better understanding of the connection between fault properties and earthquake behavior gives insight into the role of fluids in seismogenesis, the spectrum of earthquake rupture, and possible hazard at subduction zones.

Rickettsial infections and Q fever present similarly to other acute febrile illnesses, but are infrequently diagnosed because of limited diagnostic tools. Despite sporadic reports, rickettsial infections and Q fever have not been prospectively studied in Central America. We enrolled consecutive patients presenting with undifferentiated fever in western Nicaragua and collected epidemiologic and clinical data and acute and convalescent sera. We used ELISA for screening and paired sera to confirm acute (≥4-fold rise in titer) spotted fever and typhus group rickettsial infections and Q fever as well as past (stable titer) infections. Characteristics associated with both acute and past infection were assessed. We enrolled 825 patients and identified acute rickettsial infections and acute Q fever in 0.9% and 1.3%, respectively. Clinical features were non-specific and neither rickettsial infections nor Q fever were considered or treated. Further study is warranted to define the burden of these infections in Central America.

HIV viral load testing as a component of antiretroviral therapy monitoring is costly. Understanding the full costs and the major sources of inefficiency associated with viral load testing is critical for optimizing the systems and technologies that support the testing process. The objective of our study was to estimate the costs associated with viral load testing performed for antiretroviral therapy monitoring to both patients and the public healthcare system in a low-HIV prevalence, low-resource country. A detailed cost analysis was performed to understand the costs involved in each step of performing a viral load test in Nicaragua, from initial specimen collection to communication of the test results to each patient's healthcare provider. Data were compiled and cross referenced from multiple information sources: laboratory records, regional surveillance centre records, and scheduled interviews with the key healthcare providers responsible for HIV patient care in five regions of the country. The total average cost of performing a viral load test in Nicaragua varied by region, ranging from US$99.01 to US$124.58, the majority of which was at the laboratory level: $88.73 to $97.15 per specimen, depending on batch size. The average cost to clinics at which specimens were collected ranged from $3.31 to $20.92, depending on the region. The average cost per patient for transportation, food, lodging and lost income ranged from $3.70 to $14.93. The quantitative viral load test remains the single most expensive component of the process. For the patient, the distance of his or her residence from the specimen collection site is a large determinant of cost. Importantly, the efficiency of results reporting has a large impact on the cost per result delivered to the clinician and utility of the result for patient monitoring. Detailed cost analysis can identify opportunities for removing barriers to effective antiretroviral therapy monitoring programmes in limited

Rapid response of a hydrologic system to volcanic activity: Masaya volcano, Nicaragua

Hydrologic systems change in response to volcanic activity, and in turn may be sensitive indicators of volcanic activity. Here we investigate the coupled nature of magmatic and hydrologic systems using continuous multichannel time series of soil temperature collected on the flanks of Masaya volcano, Nicaragua, one of the most active volcanoes in Central America. The soil temperatures were measured in a low-temperature fumarole field located 3.5 km down the flanks of the volcano. Analysis of these time series reveals that they respond extremely rapidly, on a time scale of minutes, to changes in volcanic activity also manifested at the summit vent. These rapid temperature changes are caused by increased flow of water vapor through flank fumaroles during volcanism. The soil temperature response, ~5 °C, is repetitive and complex, with as many as 13 pulses during a single volcanic episode. Analysis of the frequency spectrum of these temperature time series shows that these anomalies are characterized by broad frequency content during volcanic activity. They are thus easily distinguished from seasonal trends, diurnal variations, or individual rainfall events, which triggered rapid transient increases in temperature during 5% of events. We suggest that the mechanism responsible for the distinctive temperature signals is rapid change in pore pressure in response to magmatism, a response that can be enhanced by meteoric water infiltration. Monitoring of distal fumaroles can therefore provide insight into coupled volcanic-hydrologic-meteorologic systems, and has potential as an inexpensive monitoring tool.

The four dengue virus serotypes (DENV1–4) cause the most prevalent mosquito-borne viral disease affecting humans worldwide. In 2009, Nicaragua experienced the largest dengue epidemic in over a decade, marked by unusual clinical presentation, as observed in two prospective studies of pediatric dengue in Managua. From August 2009–January 2010, 212 dengue cases were confirmed among 396 study participants at the National Pediatric Reference Hospital. In our parallel community-based cohort study, 170 dengue cases were recorded in 2009–10, compared to 13–65 cases in 2004–9. In both studies, significantly more patients experienced “compensated shock” (poor capillary refill plus cold extremities, tachycardia, tachypnea, and/or weak pulse) in 2009–10 than in previous years (42.5% [90/212] vs. 24.7% [82/332] in the hospital study (p<0.001) and 17% [29/170] vs. 2.2% [4/181] in the cohort study (p<0.001). Signs of poor peripheral perfusion presented significantly earlier (1–2 days) in 2009–10 than in previous years according to Kaplan-Meier survival analysis. In the hospital study, 19.8% of subjects were transferred to intensive care, compared to 7.1% in previous years – similar to the cohort study. DENV-3 predominated in 2008–9, 2009–10, and 2010–11, and full-length sequencing revealed no major genetic changes from 2008–9 to 2010–11. In 2008–9 and 2010–11, typical dengue was observed; only in 2009–10 was unusual presentation noted. Multivariate analysis revealed only “2009–10” as a significant risk factor for Dengue Fever with Compensated Shock. Interestingly, circulation of pandemic influenza A-H1N1 2009 in Managua was shifted such that it overlapped with the dengue epidemic. We hypothesize that prior influenza A H1N1 2009 infection may have modulated subsequent DENV infection, and initial results of an ongoing study suggest increased risk of shock among children with anti-H1N1-2009 antibodies. This study demonstrates that

In recent years, the use of collaborative and partnership approaches in health and agricultural research has flourished. Such approaches are frequently adopted to ensure more successful research uptake and to contribute to community empowerment through participatory research practices. At the same time that interest in research partnerships has been growing, publications on methods, models, and guidelines for building these partnerships have proliferated. However, partnership development is not necessarily as straightforward or linear a process as such literature makes it appear, particularly when the research involves divisive or contentious issues. This paper explores prevailing views on research partnerships, and also questions the applicability of partnership models using an emerging research program around gender equity and health in Fair Trade coffee cooperatives in Nicaragua as an example. Moreover, the paper introduces some of the complicated issues facing the authors as they attempt to develop and expand partnerships in this research area. The paper culminates with a series of strategies that the authors plan to use that offer alternative ways of thinking about building research partnerships concerning controversial or complex issues in the field of community health and development.

Globalization, shifting livelihoods, and their effects on natural resources on the Atlantic coast of Nicaragua

Knowledge of local peoples' livelihoods is important in understanding the use of, access to, and regulation of natural resources. Drivers of global change, including climate change and globalization, often result in shifts in local peoples' livelihood portfolios. Here, we use longitudinal data to examine how increasing market access, migration, and technology adoption have affected livelihood portfolios in a dozen communities along Nicaragua's Atlantic coast and the effects of livelihood change on terrestrial and marine wildlife. Our study communities are located in varying proximity to the terminus of the first trans-isthmian highway in this region, completed in 2008. Our results indicate that changes in livelihood portfolios, such as shifts between agriculture, fishing, and tourism, can be explained by a combination of household and community characteristics. Moreover, globalization's effects on specific livelihoods are distinct while varying both spatially and temporally. Trends in fisheries abundance, deforestation, and the management of endangered species and protected areas are better understood in the context of these shifting livelihood patterns. Moreover, this study provides new insights as to how natural resource dependent communities might decrease their vulnerability to the forces of global change.

This study was conducted to determine rural Nicaraguan health promotores' perceptions of their community's health problems, their self-identified learning needs, and resource needs. Despite the valuable contributions of promotores, there is limited research regarding unpaid volunteer promotores' perceptions of their needs in providing care to remote communities. A qualitative descriptive study of 13 unpaid, volunteer promotores in Waslala, Nicaragua, was conducted. Data were collected during individual interviews with seven promotores and two focus groups with 13 promotores. Data were analyzed by reading verbatim transcripts repeatedly and establishing general themes. Promotores confirmed the findings. Waslalan promotores described a synergy of traditional folk health beliefs and natural practices along with use of modern medications while working to meet the health needs of their communities. Without much formal training, the promotores used public health strategies to influence health behaviors and address health disparities in the communities they serve. Serving their communities and God were their motivation in their work. Recommendations include supporting efforts to meet promotores' needs regarding community health education with messages from community leaders and nurses, finding methods to financially compensate promotores, and including promotores in health program planning and evaluation. © 2012 Wiley Periodicals, Inc.

A sedimentary-based history of hurricane strikes on the southern Caribbean coast of Nicaragua

2012-11-01

Multi-millennial hurricane landfall records from the western North Atlantic indicate that landfall frequency has varied dramatically over time, punctuated by multi-centennial to millennial scale periods of hyperactivity. We extend the record geographically by presenting a paleostrike record inferred from a four-core transect from a marsh on the Caribbean coast of Nicaragua. Fossil pollen indicates that the site was a highly organic wetland from ~ 5400-4900 cal yr BP, at which time it became a shallow marine lagoon until ~ 2800 cal yr BP when it transitioned back into swamp/marsh, freshening over time, with the present fresh-to-brackish Typha marsh developing over the very recent past. Hurricane Joan, 1988, is recorded as a distinctive light-colored sand-silt-clay layer across the top of the transect, identifiable by abrupt shifts in color from the dark marsh deposits, increased grain size, and two upward-fining sequences, which are interpreted as representing the storm's traction and suspension loads. The six layers identified as hurricane-generated display temporal clustering, featuring a marked increase in landfall frequency ~ 800 cal yr BP. This pattern is anti-phase with the activity pattern previously identified from the northern Caribbean and the Atlantic coast of North America, thereby opposing the view that hyperactivity occurs simultaneously across the entire basin.

The ERTS Data Collection System makes it feasible for the first time to monitor the level of activity at widely separated volcanoes and to relay these data rapidly to one central office for analysis. While prediction of specific eruptions is still an evasive goal, early warning of a reawakening of quiescent volcanoes is now a distinct possibility. A prototypical global volcano surveillance system was established under the ERTS program. Instruments were installed in cooperation with local scientists on 15 volcanoes in Alaska, Hawaii, Washington, California, Iceland, Guatemala, El Salvador and Nicaragua. The sensors include 19 seismic event counters that count four different sizes of earthquakes and six biaxial borehole tiltmeters that measure ground tilt with a resolution of 1 microradian. Only seismic and tilt data are collected because these have been shown in the past to indicate most reliably the level of volcano activity at many different volcanoes. Furthermore, these parameters can be measured relatively easily with new instrumentation.

Cerro el Castillo is located in the NW of Nicaragua, Central America, close to the border of Honduras (Provincia Central de las Cordilleras) at 1000-1200m above sea level. In this region, small and medium-sized farms are agroforestry systems with mangos, avocados, coffee, papayas, bananas, strawberries, maize, pumpkins, beans and other vegetables. The production systems are strongly linked to facilities for raising small domestic animals and cows. Main regional agricultural production problems are steep slopes, soil erosion, varying precipitation and distribution, water management and the unstable family income. An investigation of topsoil properties with comparable management systems showed on small scales significant differences in key values of soil chemistry and mineralogy. The outline of the analytical parameters included determination of pH, electrical conductivity (EC), cation exchange capacity (CEC), organic carbon (TOC), dissolved organic carbon (DOC), total nitrogen (TN) and dissolved nitrogen (DN) in soil solution, and plant available nutrients (P and K). The soil's mineralogical composition was determined by X-ray diffraction analysis. The area is a highly weathered karst landscape within a tropical limestone region displaying different amounts of volcanic pyroclastic parent material. The dominant Nitisoils and Andosols show degraded argic and andic horizons along the upper half of the mountainside. The pH values in the topsoil are moderate from pH 5.0 to 5.6. The upland topsoil is decalcified and the amount of plant available phosphorous is very low with significant low Ca concentration at the sorption complex. The mineralogical composition points to the high weathering intensity of this area (high content of kaolinite and a lower concentration of potassium and plagioclase feldspars and andesite). Along the upper half of the mountain, the soil profiles show wider C:N ratios and lower amounts of organic matter. Topsoil at lower altitude and with a lower

Background Social inequality in child survival hampers the achievement of Millennium Development Goal 4 (MDG4). Monitoring under-five mortality in different social strata may contribute to public health policies that strive to reduce social inequalities. This population-based study examines the trends, causes, and social inequality of mortality before the age of five years in rural and urban areas in Nicaragua. Methods The study was conducted in one rural (Cuatro Santos) and one urban/rural area (León) based on data from Health and Demographic Surveillance Systems. We analyzed live births from 1990 to 2005 in the urban/rural area and from 1990 to 2008 in the rural area. The annual average rate reduction (AARR) and social under-five mortality inequality were calculated using the education level of the mother as a proxy for socio-economic position. Causes of child death were based on systematic interviews (verbal autopsy). Results Under-five mortality in all areas is declining at a rate sufficient to achieve MDG4 by 2015. Urban León showed greater reduction (AARR = 8.5%) in mortality and inequality than rural León (AARR = 4.5%) or Cuatro Santos (AARR = 5.4%). Social inequality in mortality had increased in rural León and no improvement in survival was observed among mothers who had not completed primary school. However, the poor and remote rural area Cuatro Santos was on track to reach MDG4 with equitable child survival. Most of the deaths in both areas were due to neonatal conditions and infectious diseases. Conclusions All rural and urban areas in Nicaragua included in this study were on track to reach MDG4, but social stratification in child survival showed different patterns; unfavorable patterns with increasing inequity in the peri-urban rural zone and a more equitable development in the urban as well as the poor and remote rural area. An equitable progress in child survival may also be accelerated in very poor settings. PMID:24428933

Antibiotic-resistant bacteria are a major concern in the healthcare of today, especially the increasing number of gram-negative bacteria producing β-lactamases such as extended-spectrum β-lactamases (ESBLs). However, little is known about the relationship of ESBL producers in humans and domestic and wild birds, especially in a low-income setting. Therefore, we studied the fecal carriage of ESBL-producing Escherichia coli and Klebsiella pneumoniae in healthy humans, poultry, and wild birds in the vicinity of León, Nicaragua. Three hundred fecal samples were collected during December 2012 from humans (n = 100), poultry (n = 100) and wild birds (n = 100). The samples were examined for ESBL-producing E. coli and K. pneumoniae, revealing the prevalence of 27% in humans, 13% in poultry, and 8% in wild birds. Further characterization of the ESBL-producing isolates was performed through polymerase chain reaction (PCR) (NDM, CTX-M), epidemiological typing (ERIC2-PCR), multilocus sequence typing, and sequencing. ESBL producers harbored bla CTX-M-2 , bla CTX-M-15 , bla CTX-M-22 , and bla CTX-M-3 genotypes. The bla CTX-M-15 constituted the absolute majority of ESBL genes among all samples. ERIC-PCR demonstrated highly related E. coli clones among humans, poultry, and wild birds. Clinically relevant E. coli clone ST648 was found in humans and poultry. There is a shared pool of bla CTX-M genes between humans and domesticated and wild birds in Nicaragua, and the results suggest shared clones of ESBL-producing E. coli. The study adds to the notion that wild birds and poultry can pick up antibiotic-resistant bacteria of human origin and function as a melting pot of resistance. Structured surveillance programs of antimicrobial resistance and a more regulated prescription of antibiotics are warranted in Nicaragua.

This article describes the municipal solid waste management system in Managua, Nicaragua. It updates an initial profile developed by the authors for the 2010 UN-HABITAT publication Solid Waste Management in the World's Cities and applies the methodology developed in that publication. In recent years, the municipality of Managua has been the beneficiary of a range of international cooperation projects aimed at improving municipal solid waste management in the city. The article describes how these technical assistance and infrastructure investments have changed the municipal solid waste management panorama in the city and analyses the sustainability of these changes. The article concludes that by working closely with the municipal government, the UN-HABITAT project Strengthening Capacities for Solid Waste Management in Managua was able to unite these separate efforts and situate them within a strategic framework to guide the evolution of the municipal solid waste management system in the forthcoming years. The creation of this multi-stakeholder platform allowed for the implementation of joint activities and ensured coherence in the products generated by the different projects. This approach could be replicated in other cities and in other sectors with similar effect. Developing a long term vision was essential for the advancement of municipal solid waste management in the city. Nevertheless, plan implementation may still be undermined by the pressures of the short term municipal administrative government, which emphasize operational over strategic investment. © The Author(s) 2014.

A re-assessment of aerosol size distributions from Masaya volcano (Nicaragua)

Cascade impactors were used to sample volcanic aerosol from Masaya (Nicaragua) in 2007, 2009 and 2010. Differences were found in the size distributions of volcanic aerosol between these recent campaigns and with a campaign in 2001: (1) SO 42- showed modes in both the fine (<1 μm; with low Na +/K +) and coarse (>1 μm; with high Na +/K +) fractions in all of the recent campaigns despite being unimodal in 2001 (<1 μm); (2) The modal diameters for SO 42- roughly doubled in 2009, compared to 2007 or 2010; (3) total Cl - was depleted in volcanic aerosol compared to background aerosol in all the more recent campaigns but was enriched in 2001. Other aspects of the volcanic aerosol appear to be persistent, such as a fine SO 42--H +-Na +-K + mode, which was the most abundant mode in all campaigns, and a coarse Cl --F --Mg 2+-Ca 2+ mode of lower abundance. Water uptake and speciation in the aerosol were investigated using the equilibrium model, ISORROPIA II. Results show that the coarse SO 42--rich mode deliquesces at lower relative humidity (40% RH) than the fine SO 42--rich mode (50% RH) due to increased Na +/K + in the former. The aerosol was predicted to be dry at ambient relative humidity in 2009 and dominated by NaHSO 4, KHSO 4, CaSO 4 and MgSO 4. In contrast, model results predict a liquid aerosol at ambient relative humidity in 2010. These results indicate that aerosol emissions from a volcano can vary in ionic composition and even more so in physical speciation (i.e., salts or solutions). These observations are set against a near-constant magmatic gas composition at Masaya, which highlights the significance of atmospheric and dynamic factors in the formation of volcanic aerosols.

Abstract Background and objectives The prevalence of teenage pregnancies in Nicaragua is the highest in Latin-America. This study aimed to gain insight into factors which determine the sexual behaviours concerned. Methods From July until August 2011, a door-to-door survey was conducted among adolescents living in randomly selected poor neighbourhoods of Managua. Logistic regression was used to analyse factors related to sexual onset and contraceptive use. Results Data from 2803 adolescents were analysed. Of the 475 and 299 sexually active boys and girls, 43% and 54%, respectively, reported contraceptive use. Sexual onset was positively related to increasing age, male sex, alcohol consumption and not living with the parents. Catholic boys and boys never feeling peer pressure to have sexual intercourse were more likely to report consistent condom use. Having a partner and feeling comfortable talking about sexuality with the partner were associated with hormonal contraception. Conclusions Our data identified associates of adolescents’ sexual behaviour related to personal characteristics (sex and alcohol use), to the interaction with significant others (parents, partners, peers) and to the environment (housing condition, religion). We interpreted those associates within the context of the rapidly changing society and the recently implemented health system reform in Nicaragua.

Rheumatic heart disease (RHD) results in morbidity and mortality that is disproportionate among people in developing countries compared to those living in economically developed countries. The global burden of disease is uncertain because most previous studies to determine the prevalence of RHD in children relied on clinical screening criteria that lacked the sensitivity to detect most cases. The present study was performed to determine the prevalence of RHD in children and young adults in León, Nicaragua, an area previously thought to have a high prevalence of RHD. This was an observational study of 3150 children, ages 5–15, and 489 adults, ages 20–35, randomly selected from urban and rural areas of León. Cardiopulmonary exams and echo-Doppler studies were performed on all subjects. Echo-Doppler diagnosis of RHD was based on pre-defined consensus criteria that were developed by a WHO/NIH working group. The overall prevalence of RHD in children was 48/1000 (95% C.I. = 35/1000–60/1000. The prevalence in urban children was 34/1000 and in rural children it was 80/1000. Using more stringent echo-Doppler criteria designed to diagnose definite RHD in adults, the prevalence was 22/1000 (95% C.I.=8/1000–37/1000). In conclusion, the prevalence of RHD among children and adults in this economically disadvantaged population far exceeds previously predicted rates. The findings underscore the potential health and economic burden of acute rheumatic fever and RHD and support the need for more effective measures of prevention, which may include safe, effective and affordable vaccines to prevent the streptococcal infections that trigger the disease.

Seasonal influenza affects a considerable proportion of the global population each year. We assessed the association between subnational influenza activity and temperature, specific humidity and rainfall in three Central America countries, i.e. Costa Rica, Honduras and Nicaragua. Using virologic data from each country's national influenza centre, rainfall from the Tropical Rainfall Measuring Mission and air temperature and specific humidity data from the Global Land Data Assimilation System, we applied logistic regression methods for each of the five sub-national locations studied. Influenza activity was represented by the weekly proportion of respiratory specimens that tested positive for influenza. The models were adjusted for the potentially confounding co-circulating respiratory viruses, seasonality and previous weeks' influenza activity. We found that influenza activity was proportionally associated (P<0.05) with specific humidity in all locations [odds ratio (OR) 1.21-1.56 per g/kg], while associations with temperature (OR 0.69-0.81 per °C) and rainfall (OR 1.01-1.06 per mm/day) were location-dependent. Among the meteorological parameters, specific humidity had the highest contribution (~3-15%) to the model in all but one location. As model validation, we estimated influenza activity for periods, in which the data was not used in training the models. The correlation coefficients between the estimates and the observed were ≤0.1 in 2 locations and between 0.6-0.86 in three others. In conclusion, our study revealed a proportional association between influenza activity and specific humidity in selected areas from the three Central America countries.

A three month relief operation for the 25,303 people living in the municipal area of Villanueva, Nicaragua, hit by Hurricane Mitch, was carried out jointly by the staff of an international non-government organization and an Italian Regional Hospital's staff. Health Mobile Teams joined the local health facilities (Health Centers and Health Posts) in responding to the people's urgent health problems. From their files the thirty-day post-disaster incidence of acute diarrheas (AD), respiratory tract infectious diseases (ARD), and malaria were estimated and compared with off-crisis data. New cases of leptospirosis were searched, but no control group was available. The incidence of AD and ARD increased significantly in comparison with pre-disaster data (6,798 vs. 2,849 per 100,000 inhabitants (p < 0.01) and 1,205 vs. 295 per 100,000 inhabitants (p < 0.01)). The increase in incidence of malaria was not explicit. Only three cases of leptospirosis were ascertained. The relief operators used the gathered data to make decisions to allocate the poorly available resources. The feasibility of the infectious disease surveillance and the reliability of the results under such conditions may change according to the setting. In this case study the infectious disease surveillance was feasible, and the gathered data were reliable and of some help to the relief operators in order to allocate the resources efficiently.

Momotombo volcano, Nicaragua, began erupting in December 2015 after 105 years of dormancy. Within weeks of the eruption onset, an international team of scientists began interdisciplinary studies investigating the geophysical and geochemical processes of the eruption. Our work included the installation of new seismic and geodetic networks, sampling of lava flows and ashes for geochemical and petrographic analyses, and the collection and analysis of space and ground-based radar data. Momotombo volcano has been seismically restless since at least the 1980's, when modern records are first available. Beginning in September 2013, discrete seismic swarms including events up to M4 and depths of 20 km occurred periodically. On April 10, 2014 an M6.1 earthquake occurred in Lake Managua displacing the southern flank of the volcano more than 5 cm as measured at a continuous GPS (cGPS) site. A major seismic swarm, which included an M4.7 earthquake, began on November 24, 2015, and culminated in gas and ash eruptions beginning at 7:49 am (local time) on December 1, 2015. By the evening of December 1, Momotombo was in strombolian eruption with columns to 1 km and a lava flow advancing down the northern flank. To date, there have been over 435 explosions as detected by seismic data and visually on webcam imagery, with the last explosion on April 7, 2016. Utilizing cGPS and episodic GPS observations and radar interferometry (InSAR), we did not detect any significant pre-, co-, or post-eruptive magmatic deformation. Lava samples collected from the 2015, 1905, and pre-1905 eruptions are all basaltic andesites with nearly identical major and trace element compositions, suggesting a long-lived magma body. Concentrations of metals and volatiles in ash leachates decrease over time in the first two days of the eruption. Our interdisciplinary studies allow for an integrated analysis of this strombolian eruption and its hazards.

In low-income countries renal diseases generally and chronic kidney disease (CKD) in particular represent a wide-spread and often underdiagnosed clinical problem. The aim of the cooperative project between the pediatric nephrology units of Milan, Italy, and Managua, Nicaragua was to improve the diagnosis and treatment of renal diseases and CKD in Nicaraguan children. When the project started, in 2000, there were many constraints in human and material resources in the Children's Hospital in Managua. Since 2001, a specialized Unit of Pediatric Nephrology and Urology has developed, offering free of charge basic clinical assistance to hospitalized children, and training abroad of the whole staff. Shared protocols, renovation of infrastructure and an information technology (IT) program were implemented. In 2003, renal replacement therapy (RRT) for selected children was initiated, along with a network of six department hospitals in 2005 and, in 2007, a CKD prevention program in the most peripheral Health Units, so that 61% of the Nicaraguan pediatric population is now covered by the project. To ensure implementation of the project, applications for funds to Italian private and public institutions were made and a Nicaraguan charity foundation was activated. The Nicaraguan Ministry of Health and the hospital directors were always involved in the plans of the development of the project and accepted the progressive transfer of the costs to the government, throughout the 9-year duration of the project. The IT program, inclusive of a database of children with kidney and other urinary tract (UT) diseases and a web connection between Milan and Managua, was crucial in monitoring the activities and providing epidemiological data, in order to better allocate resources. The clinical activities and the number of children managed in Managua in 2008 are similar to those of pediatric nephrology units worldwide and depict the level of clinical autonomy achieved.

To evaluate the impact of a community-wide intervention to increase HIV/AIDS-related knowledge, change attitudes and increase safer-sex practices in Managua, Nicaragua. Household-based health education intervention trial comprising a knowledge, attitudes and practices (KAP) survey at baseline, a health education intervention and a follow-up KAP survey. Four neighbourhoods were included, two received the intervention, and the other two served as controls. Randomly selected residents aged 15-45 years were interviewed at baseline (n = 2160) and follow-up (n = 2271) using an identical questionnaire. The intervention consisted of a health education campaign that emphasized HIV transmission and condom use. OUTCOME AND ANALYSIS: Knowledge levels regarding transmission and prevention of HIV infection, self-reported use of condoms, levels of worries about HIV/AIDS and perceptions of personal risk of HIV infection. Comparisons between baseline and follow-up employed chi 2 tests with continuity correction. The influence of the intervention was examined in multivariate logistic models including an appropriate interaction term. Intervention and control samples were comparable with regard to sex, age, and age at first intercourse. Significantly less intervention residents had formal education (P < 0.001). At baseline, outcome variables were generally similar in control and intervention samples. Condom use increased from 9 to 16% (P = 0.003) among intervention women, but only from 9 to 11% (P = 0.5) in control women (test for interaction, P = 0.08). Among men, increases were from 31 to 41% (P < 0.001) and from 30 to 37% (P = 0.06), respectively (test for interaction, P = 0.3). Levels of worries about HIV/AIDS decreased in all groups, but perception of individual risk increased only among intervention women (test for interaction, P = 0.02). This household-targeted health education intervention appears to have had some effect; however, sustained efforts are needed further to

An epidemic of Mesoamerican Nephropathy (MeN) is killing thousands of agricultural workers along the Pacific coast of Central America, but the natural history and aetiology of the disease remain poorly understood. We have recently commenced a community-based longitudinal study to investigate Chronic Kidney Disease (CKD) in Nicaragua. Although logistically challenging, study designs of this type have the potential to provide important insights that other study designs cannot. In this paper we discuss the rationale for conducting this study and summarize the findings of the baseline visit. The baseline visit of the community-based cohort study was conducted in 9 communities in the North Western Nicaragua in October and November 2014. All of the young men, and a random sample of young women (aged 18-30) without a pre-existing diagnosis of CKD were invited to participate. Glomerular filtration rate (eGFR) was estimated with CKD-EPI equation, along with clinical measurements, questionnaires, biological and environmental samples to evaluate participants' exposures to proposed risk factors for MeN. We identified 520 young adults (286 males and 234 females) in the 9 different communities. Of these, 16 males with self-reported CKD and 5 females with diagnoses of either diabetes or hypertension were excluded from the study population. All remaining 270 men and 90 women, selected at random, were then invited to participate in the study; 350 (97%) agreed to participate. At baseline, 29 (11%) men and 1 (1%) woman had an eGFR <90 mL/min/1.73 m 2 . Conducting a community based study of this type requires active the involvement of communities and commitment from local leaders. Furthermore, a research team with strong links to the area and broad understanding of the context of the problem being studied is essential. The key findings will arise from follow-up, but it is striking that 5% of males under aged 30 had to be excluded because of pre-existing kidney disease, and that

Background Dengue is the most prevalent mosquito-borne viral disease in humans and a major urban public health problem worldwide. Methods A prospective cohort study of ~3,800 children initially aged 2-9 years old was established in Managua, Nicaragua, in 2004 to study the natural history of dengue transmission in an urban pediatric population. Blood samples from healthy subjects were collected annually prior to the dengue season, and identification of dengue cases occurred via enhanced passive surveillance at the study health center. Results Over the first four years of the study, seroprevalence of anti-dengue virus (DENV) antibodies increased from 22-40% in the 2-year-old cohort and 90-95% in the 9-year-old cohort. The incidence of symptomatic dengue cases and the ratio of inapparent to symptomatic DENV infection varied substantially year-to-year. The switch in dominant transmission from DENV-1 to DENV-2 was accompanied by an increase in disease severity but, paradoxically, a decrease in transmission. Phylogeographic analysis of full-length DENV-2 sequences revealed strong geographic clustering of dengue cases. Conclusions This large-scale cohort study of dengue in the Americas demonstrates year-to-year variation of dengue within a pediatric population, revealing expected patterns in transmission while highlighting the impact of interventions, climate, and viral evolution.

We study the lithology, structure, and emplacement of two debris-avalanche deposits (DADs) with contrasting origins and materials from the Quaternary-Holocene Mombacho Volcano, Nicaragua. A clear comparison is possible because both DADs were emplaced onto similar nearly flat (3° slope) topography with no apparent barrier to transport. This lack of confinement allows us to study, in nature, the perfect case scenario of a freely spreading avalanche. In addition, there is good evidence that no substratum was incorporated in the events during flow, so facies changes are related only to internal dynamics. Mombacho shows evidence of at least three large flank collapses, producing the two well-preserved debris avalanches of this study; one on its northern flank, “Las Isletas,” directed northeast, and the other on its southern flank, “El Crater,” directed south. Other south-eastern features indicate that the debris-avalanche corresponding to the third collapse (La Danta) occurred before Las Isletas and El Crater events. The materials involved in each event were similar, except in their alteration state and in the amount of substrata initially included in the collapse. While “El Crater” avalanche shows no signs of substratum involvement and has characteristics of a hydrothermal weakening-related collapse, the “Las Isletas” avalanche involves significant substratum and was generated by gravity spreading-related failure. The latter avalanche may have interacted with Lake Nicaragua during transport, in which case its run-out could have been modified. Through a detailed morphological and structural description of the Mombacho avalanches, we provide two contrasting examples of non-eruptive volcanic flank collapse. We show that, remarkably, even with two distinct collapse mechanisms, the debris avalanches developed the same gross stratigraphy of a coarse layer above a fine layer. This fine layer provided a low friction basal slide layer. Whereas DAD layering and

This discussion describes the impact of a World Food Program (WFP) project on the food consumption of preschool Miskito Indian children in eastern Nicaragua. The data were collected during January, March, and May 1977 by the recall method for the random sample of 252 children ranging in age from 6 months-5 years. 24-hour recalls were obtained from mothers or other persons responsible for childfeeding. Homes were visited once per day in the late afternoon. Food intakes for the 24 hours immediately preceding the interview were recorded using food models and marked dishes as aids. The amount of breastmilk consumed was not estimated. In March, homes of selected children were visited 3 days in succession with 24-hour food intakes recorded for each day. To evaluate the contribution of different food sources to the children's diets, the following classification was used: home--food acquired through the family's own agriculture, hunting, fishing, or gathering, or received as a gift; market--food purchased in village stores or a food combination made with purchased ingredients; mixed--food purchased from another family or a food combination made with ingredients from a mixture of home, market, and National Development Institute (INFONAC) sources; and INFONAC--food items from the INFONAC project or a food combination made from a majority of INFONAC ingredients, which consisted of oatmeal, whole wheat, and dried skim milk. Marked changes occurred in food sources over the 5-month period. Data for January and March were relatively similar but, in May, there was a significant increase in the contribution of INFONAC foods to the consumption of almost all nutrients. This shift was due to a decrease in the availabiltiy of "home" foods as well as to increased consumption of INFONAC foods. The percentage contributions of the 4 different food sources to the diets of Miskito Indian children cannot indicate the actual nutrient adequacy of the food consumed. Total food consumption

Dengue is a major public health problem in tropical and subtropical regions; however, under-reporting of cases to national surveillance systems hinders accurate knowledge of disease burden and costs. Laboratory-confirmed dengue cases identified through the Nicaraguan Pediatric Dengue Cohort Study (PDCS) were compared to those reported from other health facilities in Managua to the National Epidemiologic Surveillance (NES) program of the Nicaraguan Ministry of Health. Compared to reporting among similar pediatric populations in Managua, the PDCS identified 14 to 28 (average 21.3) times more dengue cases each year per 100,000 persons than were reported to the NES. Applying these annual expansion factors to national-level data, we estimate that the incidence of confirmed pediatric dengue throughout Nicaragua ranged from 300 to 1000 cases per 100,000 persons. We have estimated a much higher incidence of dengue than reported by the Ministry of Health. A country-specific expansion factor for dengue that allows for a more accurate estimate of incidence may aid governments and other institutions calculating disease burden, costs, resource needs for prevention and treatment, and the economic benefits of drug and vaccine development.

Nicaraguan Midas cichlids from crater lakes have recently attracted attention as potential model systems for speciation research, but no attempt has been made to comprehensively reconstruct phylogenetic relationships of this highly diverse and recently evolved species complex. We present a first AFLP (2793 loci) and mtDNA based phylogenetic hypothesis including all described and several undescribed species from six crater lakes (Apoyeque, Apoyo, Asososca Leon, Masaya, Tiscapa and Xiloá), the two great Lakes Managua and Nicaragua and the San Juan River. Our analyses demonstrate that the relationships between the Midas cichlid members are complex, and that phylogenetic information from different markers and methods do not always yield congruent results. Nevertheless, monophyly support for crater lake assemblages from Lakes Apoyeque, Apoyo, A. Leon is high as compared to those from L. Xiloá indicating occurrence of sympatric speciation. Further, we demonstrate that a 'three species' concept for the Midas cichlid complex is inapplicable and consequently that an individualized and voucher based approach in speciation research of the Midas cichlid complex is necessary at least as long as there is no comprehensive revision of the species complex available.

OBJECTIVES: To explore whether symptoms resulted from pesticide spray drift on residentially exposed populations in rural Nicaragua. METHODS: 100 residents, each 10 years of age or older, were randomly selected from a Nicaraguan community surrounded by actively sprayed cotton fields (the exposed community) and from a socioeconomically similar community far from agricultural spraying (the control community). Subjects working with pesticides were excluded, and the study was conducted at the end of the 1990 cotton spraying season (August-December). Demographic information, exposure questions, and prevalence of 11 acute symptoms and 17 chronic symptoms were gathered from a structured interview. Finger stick erythrocyte cholinesterase (AChE) was measured with a portable colorimeter. Acute symptoms were grouped according to their previously known associations with cholinesterase (ChE) inhibitors into four ordinal categories (asymptomatic, non-specific, possible, probable). RESULTS: Residents from the exposed community were significantly more likely to report recently sighting a spray plane near their community, exposure to pesticide from drift, crossing recently sprayed fields, eating home grown food, and feeling ill after drift exposure. The mean AChE value was significantly lower for residents of the exposed community (4.9 v 5.3 IU/dl). The proportion of subjects complaining of one or more chronic or acute symptoms was significantly higher for the exposed community (87%) than for the controls (53%). Odds ratios for residents in the exposed community, by symptom categories, were non-specific 1.6 (95% confidence interval (95% CI) 0-8 to 3.2), possible 4.1 (95% CI 1.7 to 10.2), and probable 9.93 (95% CI 2-9 to 34.4). CONCLUSION: These findings indicate a strong association between exposure to aerial pesticides and symptoms. This study should be replicated with more quantitative exposure measures, for if confirmed, the results have relevance for millions in rural

Significant cocoa production in the municipality of Waslala, Nicaragua, began in 1961. Since the 1980s, its economic importance to rural smallholders increased, and the region now contributes more than 50% of national cocoa bean production. This research aimed to assist local farmers to develop production of high-value cocoa based on optimal use of cacao biodiversity. Using microsatellite markers, the allelic composition and genetic structure of cacao was assessed from 44 representative plantings and two unmanaged trees. The population at Waslala consists of only three putative founder genotype spectra (lineages). Two (B and R) were introduced during the past 50 years and occur in >95% of all trees sampled, indicating high rates of outcrossing. Based on intermediate allelic diversity, there was large farm-to-farm multilocus genotypic variation. GIS analysis revealed unequal distribution of the genotype spectra, with R being frequent within a 2 km corridor along roads, and B at more remote sites with lower precipitation. The third lineage, Y, was detected in the two forest trees. For explaining the spatial stratification of the genotype spectra, both human intervention and a combination of management and selection driven by environmental conditions, appear responsible. Genotypes of individual trees were highly diverse across plantings, thus enabling selection for farm-specific qualities. On-farm populations can currently be most clearly recognized by the degree of the contribution of the three genotype spectra. Of two possible strategies for future development of cacao in Waslala, i.e. introducing more unrelated germplasm, or working with existing on-site diversity, the latter seems most appropriate. Superior genotypes could be selected by their specific composite genotype spectra as soon as associations with desired quality traits are established, and clonally multiplied.

The Momotombo volcano has a special place in the history of Nicaragua. It is perfectly visible from the Capital, Managua, and from the major city of Leon. The old capital "Leon Viejo", founded in 1524 was abandoned in 1610, after a series of earthquakes and some major eruptions from Momotombo. The site was subsequently covered by Momotombo ash. A major geothermal power plant stands at the base of the volcano. Momotombo had been dormant for a hundred years, but had maintained high fumarole temperatures (900°C), indicating magma had been close to the surface for decades. In recent years, seismic activity has increased around the volcano. In December 2015, after a short ash eruption phase the volcano erupted lava, then a string of Vulcanian explosions. The volcano is now in a phase of small Vulcanian explosions and degassing. The Leon Viejo World Heritage site is at risk to mainly ash fall from the volcano, but the abandonment of the old city was primarily due to earthquakes. Additional risks come from high rainfall during hurricanes. There is an obvious link between the cultural site (inscribed under UNESCO cultural criteria) and the geological environment. First, the reactivation of Momotombo volcano makes it more important to revise the hazard of the site. At the same time, Leon Viejo can provide a portal for outreach related to the volcano and for geological risk in general. To maximise this, we provide a geosite inventory of the main features of Momotombo, and it's environs, that can be used as the first base for such studies. The volcano was visited by many adventure tourists before the 2015/2016 eruption, but is out of bounds at present. Alternative routes, around the volcano could be made, to adapt to the new situation and to show to visitors more of the geodiversity of this fascinating volcano-tectonic and cultural area.

Background Millennium Development Goal 1 encourages local initiatives for the eradication of extreme poverty. However, monitoring is indispensable to insure that actions performed at higher policy levels attain success. Poverty in rural areas in low- and middle-income countries remains chronic. Nevertheless, a rural area (Cuatro Santos) in northern Nicaragua has made substantial progress toward poverty eradication by 2015. We examined the level of poverty there and described interventions aimed at reducing it. Methods Household data collected from a Health and Demographic Surveillance System was used to analyze poverty and the transition out of it, as well as background information on family members. In the follow-up, information about specific interventions (i.e., installation of piped drinking water, latrines, access to microcredit, home gardening, and technical education) linked them to the demographic data. A propensity score was used to measure the association between the interventions and the resulting transition from poverty. Results Between 2004 and 2009, poverty was reduced as a number of interventions increased. Although microcredit was inequitably distributed across the population, combined with home gardening and technical training, it resulted in significant poverty reduction in this rural area. Conclusions Sustainable interventions reduced poverty in the rural areas studied by about one- third. PMID:22894144

Nicaragua's Bosawás Biosphere Reserve is a vast forested area inhabited largely by indigenous Mayangna and Miskitu people. Most Bosawás residents rely on subsistence hunting and swidden agriculture, and hunting dogs are important for finding and securing wild game. We investigated the health of hunting dogs in three communities differing in location, size, and economy. Dogs in all communities were nutritionally compromised and experienced a heavy burden of disease. Seroprevalence of canine distemper, canine parvovirus, Rickettsia rickettsii, and Leptospira spp. exceeded 50% of dogs. At least one dog was actively shedding leptospires in urine, and many dogs were anemic and/or dehydrated. These dogs interact with wildlife in the forest and humans and domestic livestock in the communities, and may therefore serve as sources of zoonotic and wildlife diseases. Bosawás represents one of the largest intact tracts of habitat for jaguars (Panthera onca) in Central America, and given that these communities are located within the forest, jaguars may be at risk from disease spillover from hunting dogs. Dog owners reported that four of 49 dogs had been attacked and killed by jaguars in the past year, and that retaliatory killing of jaguars was sometimes practiced. Disease spillover from dogs to wildlife could occur both in the course of dogs' hunting activities as well as during jaguar attacks. A better understanding of dog depredation by jaguars, pathogen exposure in jaguars, and a management strategy for the hunting dog population, are urgently needed to mitigate these dual threats to jaguars, improve the lives of hunting dogs, and safeguard the health of their owners.

Cerro Negro, Nicaragua: A key Mars Analog Environment for Acid-Sulfate Weathering

Sulfate-rich bedrock has been discovered in many locations on Mars and has been studied by both orbiting spacecraft and landers. It appears that in most cases these minerals are produced by acid-sulfate weathering of igneous rocks, which may have been a widespread process for the first billion years of Mars' history. The origin of life on Earth may have occurred in iron-sulfur hydrothermal settings and it is conceivable that early Mars had similar environmental conditions. An excellent terrestrial analog for acid- sulfate weathering of Mars-like basalts exists at Cerro Negro (CN), Nicaragua, where sulfur-bearing gases interact with recently erupted basaltic ash in numerous fumaroles. To date, we have made two expeditions to CN to assess the chemical, mineralogical, and biological conditions. At the fumaroles pH ranges from <1 to 5 and temperatures range from 40 to 400° C. Basalts with a chemical composition very similar to those on Mars are being chemically altered in the solfatara setting. In a few years, freshly erupted basalt can be converted into predominately Ca-, Mg-, and Fe-sulfates, Fe-hydroxides (including jarosite), clays, and free silica. Altered rocks have up to 30 wt% SO3 equivalent, which is similar to the Meridiani Planum bedrocks and inferred in other sulfate-bearing bedrock on Mars. Moreover, heavily weathered rocks have silica contents up to 80 wt%, similar to silica-rich soils at Gusev Crater that possibly formed in hydrothermal environments. Samples were collected for biological analysis including enrichment and isolation of novel thermophiles as well as molecular characterization of thermophile diversity. The low water and nutrient levels found in solfatara environments lead to less biomass when compared to hot springs with similar geochemical conditions. Nonetheless, microbes are thriving in these hot, acidic vent environments. At Cerro Negro solfatara, we are characterizing the metabolic and phylogenetic diversity of resident microbial

In Nicaragua, the principal cause of infant mortality is diarrhea, which is responsible for 40% of these deaths annually. This statistic reflects the low usage of health services and oral rehydration therapy (ORT). In an effort to improve the situation, several studies were carried out in Villa Carlos Fonseca municipio. This report describes two of those studies, one ethnographic and the other epidemiologic (conducted in 1989 and 1990, respectively), to find out beliefs and traditional health practices and their influence on the way in which mothers responded to their children's diarrheal illness. The ethnographic study involved interviewing 70 mothers with an average age of 28 years who had children under 2 years of age. The children represented two groups: one at high risk for diarrhea and the other at low risk. The objectives were to learn the traditional names for diarrhea, the perception of risk, and the treatments that were used. The epidemiologic study included 391 mothers over 14 years of age with one or more children under age 5 years, of whom 215 had had diarrhea in the two weeks preceding the survey. The objectives were to describe local beliefs and health practices and to determine the incidence of diarrheas according to the diagnosis made by the mothers. At least 12 types of diarrhea were identified, for which terms such as "empacho" and "sol de vista" were used. In most cases, the mothers had more confidence in folkloric treatments that they themselves or the traditional healers (curanderos) applied than in the services offered at health centers. This attitude limited their use of health services and ORT, although it was observed that in certain cases traditional treatments were used in combination with those of western medicine. There was a direct but nonsignificant correlation between the level of schooling of the mothers and the frequency with which they visited the health center. The authors suggest the effects of massages, herbal baths, and other

The diversity, composition and structure of vegetation in a cattle landscape in Matiguás, Nicaragua was characterized, and the floristic and structural differences of six types of habitats (secondary forests, riparian forests, charrales, live fences and pastures with high and low tree cover) were compared. A total of 3 949 trees of 180 species and 52 families were recorded. Forty six percent of the total trees reported for the landscape were represented by Guazuma ulmifolia (18.5%), Bursera simaruha (13.2%), Tabebuia rosea (6.3%), Enterolobium cyclocarpum (4.2%) and Albizia saman (3.4%). Many of the dominant species in the landscape were typical of open and disturbed areas. There were significant differences between the different habitats in the patterns of tree species richness, abundance, diversity, structure and floristic composition. The riparian forests had greater tree richness (p=0.0001) and diversity (p=0.0009) than other habitats. The floristic composition varied across habitats. with pairs of habitats sharing between 18.4 and 51.6% of the same tree species, and with clear differences in composition between the forested (riparian and secondary forests) and agricultural habitats. Of the habitats studied, the riparian forests and secondary forests seem to have greatest value for the conservation of the flora in the agropaisaje because they have the greatest species richness, and maintain small populations of endangered species. On the basis of the study, we recommend including agricultural landscapes in strategies to conserve tree diversity and suggest measures to ensure the maintenance of tree diversity in the Matiguas landscape.

The distribution of groundwater beneath Masaya Volcano, in Nicaragua, and its surrounding caldera was characterized using the transient electromagnetic method (TEM). Multiple soundings were conducted at 30 sites. Models of the TEM data consistently indicate a resistive layer that is underlain by one or more conductive layers. These two layers represent the unsaturated and saturated zones, respectively, with the boundary between them indicating the water-table elevation. A map of the TEM data shows that the water table in the caldera is a subdued replica of the topography, with higher elevations beneath the edifice in the south-central caldera and lower elevations in the eastern caldera, coinciding with the elevation of Laguna de Masaya. These TEM data, combined with regional hydrologic data, indicate that the caldera in hydrologically isolated from the surrounding region, with as much as 60??m of difference in elevation of the groundwater table across caldera-bounding faults. The water-table information and estimates of fluxes of water through the system were used to constrain a numerical simulation of groundwater flow. The simulation results indicate that basalt flows in the outer parts of the caldera have a relatively high transmissivity, whereas the central edifice has a substantially lower transmissivity. A layer of relatively high transmissivity must be present at depth within the edifice in order to deliver the observed flux of water and steam to the active vent. This hydrologic information about the caldera provides a baseline for assessing the response of this isolated groundwater system to future changes in magmatic activity. ?? 2007.

We investigate geologic controls on circulation in the shallow hydrothermal system of Masaya volcano, Nicaragua, and their relationship to surface diffuse degassing. On a local scale (~250 m), relatively impermeable normal faults dipping at ~60° control the flowpath of water vapor and other gases in the vadose zone. These shallow normal faults are identified by modeling of a NE-SW trending magnetic anomaly of up to 2300 nT that corresponds to a topographic offset. Elevated SP and CO2 to the NW of the faults and an absence of CO2 to the SE suggest that these faults are barriers to flow. TOUGH2 numerical models of fluid circulation show enhanced flow through the footwalls of the faults, and corresponding increased mass flow and temperature at the surface (diffuse degassing zones). On a larger scale, TOUGH2 modeling suggests that groundwater convection may be occurring in a 3-4 km radial fracture zone transecting the entire flank of the volcano. Hot water rising uniformly into the base of the model at 1 x 10-5 kg/m2s results in convection that focuses heat and fluid and can explain the three distinct diffuse degassing zones distributed along the fracture. Our data and models suggest that the unusually active surface degassing zones at Masaya volcano can result purely from uniform heat and fluid flux at depth that is complicated by groundwater convection and permeability variations in the upper few km. Therefore isolating the effects of subsurface geology is vital when trying to interpret diffuse degassing in light of volcanic activity.

Mesoamerican nephropathy (MeN) is a kidney disease of unknown cause that mainly affects working-age men in Central America. Despite being a major cause of morbidity and mortality in this region, its clinical characteristics have not been well defined. Cross-sectional family-based study. 266 members of 24 families with high chronic kidney disease (CKD) burdens in a MeN hotspot in Northwestern Nicaragua. We compared clinical and biochemical characteristics of affected individuals first with their unaffected relatives and then with NHANES (National Health and Nutrition Examination Survey) participants with CKD in order to reveal identifying features of MeN. CKD defined as serum creatinine level ≥ 1.5mg/dL in men and ≥1.4mg/dL in women. Clinical and biochemical parameters, including serum sodium, potassium, bicarbonate, calcium, magnesium, phosphorus, and uric acid. Hyperuricemia, in many cases severe, was common among patients with MeN. Uric acid levels in patients with MeN were higher than those in NHANES participants (mean, 9.6 vs 7.4mg/dL for men in each group) despite more frequent use of uric acid-lowering medications in Nicaraguan individuals (71.7% vs 11.2%). In multivariable linear mixed-effects regression analysis, uric acid levels were 2.0mg/dL (95% CI, 1.0-3.0; P<0.001) higher in patients with MeN compared with their NHANES counterparts after adjusting for age, estimated glomerular filtration rate, and uric acid-lowering therapies. In contrast to prior reports, hyponatremia and hypokalemia were not common. CKD defined by single serum creatinine measurement; population likely not representative of full MeN phenotype spectrum across Central America; major differences between MeN and NHANES groups in important characteristics such as age, ancestry, and recruitment method. Hyperuricemia out of proportion to the degree of decreased kidney function was common among Nicaraguan patients with MeN. Our results suggest that rather than being solely a consequence

Discrete locales of sulfate-rich bedrocks exist on Mars and in many cases represent the products of acid-sulfate alteration of martian basalt. In some places, the products have been attributed to hydrothermal processes from local volcanism. In order to evaluate the habitability of such an environment, we are investigating the geochemical and biological composition of active fumaroles at Cerro Negro Volcano, Nicaragua, where fresh basaltic cinders similar in composition to martian basalts are altered by acidic, sulfur-bearing gases. Temperatures at active fumaroles can reach as high as 400°C and the pH of the steam ranges from <0 to 5. Adjacent to some fumaroles, silica is being precipitated from condensing steam on the crater walls and endolithic photosynthetic mats are found at 1-2 cm depth within these silica deposits. We have analyzed one of these mats, Monkey Cheek (T=65°C, pH ~4.5), for both Archaeal and Bacterial diversity. Cloning of PCR-amplified 16S rRNA genes reveals a diverse community of Bacteria, with eight phyla represented. The most common bacterial sequences belonged to the Cyanobacteria and Ktedonobacteria, however Actinobacteria, alpha-Proteobacteria and Acidobacteria were also identified. Many of the cyanobacterial sequences were similar to those of the eukaryotic Cyanidiales, red algae that inhabit acidic, geothermal environments. Many of sequences related to Ktedonobacteria and Actinobacteria have also been found in acid mine drainage environments. The Archaeal community was far less diverse, with sequences matching those of unclassified Desulfurococcales and unclassified Thermoprotei. These sequences were more distant from isolated species than the bacterial sequences. Similar bacterial and archaeal communities have been found in hot spring environments in Yellowstone National Park, Greenland, Iceland, New Zealand and Costa Rica. Some of Mars' volcanoes were active for billions of years and by analogy to Cerro Negro, may have hosted

Payment schemes for hydrological ecosystem services as a political instrument for the sustainable management of natural resources and poverty reduction - a case study from Belén, Nicaragua

The importance of intact ecosystems for human-wellbeing as well as the dependence on functions and services they provide is undoubted. But still neither the costs of ecosystem degradation nor the benefits from ecosystem functions and services appear on socio-economic balance sheets when development takes place. Consequently overuse of natural resources is socio-economically promoted by conventional resource management policies and external effects (externalities), equally positives and negatives, remain unregarded. In this context the potential of payments for hydrological ecosystem services as a political instrument to foster sustainable natural resource use, and rural development shall be investigated. This paper introduces the principle concept of such payments, presents a case study from Nicaragua and highlights preliminary effects of the application of this instrument on natural resource use and development.

To test whether community mobilization adds effectiveness to conventional dengue control. Pragmatic open label parallel group cluster randomized controlled trial. Those assessing the outcomes and analyzing the data were blinded to group assignment. Centralized computerized randomization after the baseline study allocated half the sites to intervention, stratified by country, evidence of recent dengue virus infection in children aged 3-9, and vector indices. Random sample of communities in Managua, capital of Nicaragua, and three coastal regions in Guerrero State in the south of Mexico. Residents in a random sample of census enumeration areas across both countries: 75 intervention and 75 control clusters (about 140 households each) were randomized and analyzed (60 clusters in Nicaragua and 90 in Mexico), including 85,182 residents in 18,838 households. A community mobilization protocol began with community discussion of baseline results. Each intervention cluster adapted the basic intervention-chemical-free prevention of mosquito reproduction-to its own circumstances. All clusters continued the government run dengue control program. Primary outcomes per protocol were self reported cases of dengue, serological evidence of recent dengue virus infection, and conventional entomological indices (house index: households with larvae or pupae/households examined; container index: containers with larvae or pupae/containers examined; Breteau index: containers with larvae or pupae/households examined; and pupae per person: pupae found/number of residents). Per protocol secondary analysis examined the effect of Camino Verde in the context of temephos use. With cluster as the unit of analysis, serological evidence from intervention sites showed a lower risk of infection with dengue virus in children (relative risk reduction 29.5%, 95% confidence interval 3.8% to 55.3%), fewer reports of dengue illness (24.7%, 1.8% to 51.2%), fewer houses with larvae or pupae among houses visited

Chagas disease is one of the most serious health problems in Latin America. Because the disease is transmitted mainly by triatomine vectors, a three-phase vector control strategy was used to reduce its vector-borne transmission. In Nicaragua, we implemented an indoor insecticide spraying program in five northern departments to reduce house infestation by Triatoma dimidiata. The spraying program was performed in two rounds. After each round, we conducted entomological evaluation to compare the vector infestation level before and after spraying. A total of 66,200 and 44,683 houses were sprayed in the first and second spraying rounds, respectively. The entomological evaluation showed that the proportion of houses infested by T. dimidiata was reduced from 17.0% to 3.0% after the first spraying, which was statistically significant (P < 0.0001). However, the second spraying round did not demonstrate clear effectiveness. Space-time analysis revealed that reinfestation of T. dimidiata is more likely to occur in clusters where the pre-spray infestation level is high. Here we discuss how large-scale insecticide spraying is neither effective nor affordable when T. dimidiata is widely distributed at low infestation levels. Further challenges involve research on T. dimidiata reinfestation, diversification of vector control strategies, and implementation of sustainable vector surveillance. © The American Society of Tropical Medicine and Hygiene.

We discuss two ethical issues raised by Camino Verde, a 2011-2012 cluster-randomised controlled trial in Mexico and Nicaragua, that reduced dengue risk though community mobilisation. The issues arise from the approach adopted by the intervention, one called Socialisation of Evidence for Participatory Action. Community volunteer teams informed householders of evidence about dengue, its costs and the life-cycle of Aedes aegypti mosquitoes, while showing them the mosquito larvae in their own water receptacles, without prescribing solutions. Each community responded in an informed manner but on its own terms. The approach involves partnerships with communities, presenting evidence in a way that brings conflicting views and interests to the surface and encourages communities themselves to deal with the resulting tensions.One such tension is that between individual and community rights. This tension can be resolved creatively in concrete day-to-day circumstances provided those seeking to persuade their neighbours to join in efforts to benefit community health do so in an atmosphere of dialogue and with respect for personal autonomy.A second tension arises between researchers' responsibilities for ethical conduct of research and community autonomy in the conduct of an intervention. An ethic of respect for individual and community autonomy must infuse community intervention research from its inception, because as researchers succeed in fostering community self-determination their direct influence in ethical matters diminishes.

Community attributes have been gradually recognized as critical determinants shaping sexual behaviors in young population; nevertheless, most of the published studies were conducted in high income countries. The study aims to examine the association between community social capital with the time to sexual onset and to first birth in Central America. Building upon the 2011/12 Demographic and Health Survey conducted in Nicaragua, we identified a sample of 2766 community-dwelling female adolescents aged 15 to 19 years. Multilevel survival analyses were performed to estimate the risks linked with three domains of community social capital (i.e., norms, resource and social network). Higher prevalence of female sexual debut (norms) and higher proportion of secondary school or higher education (resource) in the community are associated with an earlier age of sexual debut by 47 % (p < 0.05) and 16 %, respectively (p < 0.001). Living in a community with a high proportion of females having a child increases the hazard of teen birth (p < 0.001) and resource is negatively associated with teen childbearing (p < 0.05). Residential stability and community religious composition (social network) were not linked with teen-onset sex and birth. The norm and resource aspects of social capital appeared differentially associated with adolescent sexual and reproductive behaviors. Interventions aiming to tackle unfavorable sexual and reproductive outcomes in young people should be devised and implemented with integration of social process.

Corridors are critical elements in the long-term conservation of wide-ranging species like the jaguar (Panthera onca). Jaguar corridors across the range of the species were initially identified using a GIS-based least-cost corridor model. However, due to inherent errors in remotely sensed data and model uncertainties, these corridors warrant field verification before conservation efforts can begin. We developed a novel corridor assessment protocol based on interview data and site occupancy modeling. We divided our pilot study area, in southeastern Nicaragua, into 71, 6. ??. 6 km sampling units and conducted 160 structured interviews with local residents. Interviews were designed to collect data on jaguar and seven prey species so that detection/non-detection matrices could be constructed for each sampling unit. Jaguars were reportedly detected in 57% of the sampling units and had a detection probability of 28%. With the exception of white-lipped peccary, prey species were reportedly detected in 82-100% of the sampling units. Though the use of interview data may violate some assumptions of the occupancy modeling approach for determining 'proportion of area occupied', we countered these shortcomings through study design and interpreting the occupancy parameter, psi, as 'probability of habitat used'. Probability of habitat use was modeled for each target species using single state or multistate models. A combination of the estimated probabilities of habitat use for jaguar and prey was selected to identify the final jaguar corridor. This protocol provides an efficient field methodology for identifying corridors for easily-identifiable species, across large study areas comprised of unprotected, private lands. ?? 2010 Elsevier Ltd.

We report the results of fourteen soil CO2 efflux surveys by the closed accumulation chamber method at Cerro Negro volcano, Nicaragua. The surveys were undertaken from 1999 to 2016 to constrain the diffuse CO2 emission from this volcano and to evaluate the spatial and temporal variations of CO2 degassing rate in relation to the eruptive cycle. Cerro Negro is an active basaltic volcano belonging to the active Central American Volcanic Arc which includes a 1,100 Km long chain of 41 active volcanoes from Guatemala to Panama. Cerro Negro first erupted in 1850 and has experienced 21 eruptive eruptions with inter eruptive average periods between 7 and 9 years. Since the last eruption occurred on 5 August 1999, with erupted lava flows and ash clouds together with gas emissions, a collaborative research program between INETER and ITER/INVOLCAN has been established for monitoring diffuse CO2 emissions from this volcano. The first survey carried out at Cerro Negro was in December 1999, just 3 months after the 1999 eruption, with a total diffuse CO2 emission output estimated on 1,869 ± 197 td-1. The second survey carried out in March 2003, three years after the eruption, yielded a value of 432 ± 54 td-1. Both values that can be considered within the post-eruptive phase. The last survey performed at Cerro Negro was in November 2016, with an estimated diffuse CO2 emission of 63 ± 14 tṡd-1and soil CO2 efflux values ranging from non-detectable (˜0.5 g m-2 d-1) up to 7264 g m-2 d-1. The long-term record of diffuse CO2 emissions at Cerro Negro shows small temporal variations in CO2 emissions with a peak in 2004 (256 ± 26 td-1) followed by a peak in seismicity. Except this value, the rest of estimated values can be considered within the inter-eruptive phase, period during which a decreasing trend on the total diffuse CO2 output has been observed, with estimates between 10 and 83 tṡd-1. Regarding to the spatial distribution of diffuse CO2 values, most of relatively high CO2

Waste picker livelihoods and inclusive neoliberal municipal solid waste management policies: The case of the La Chureca garbage dump site in Managua, Nicaragua.

The modernization (i.e. mechanization, formalization, and capital intensification) and enclosure of municipal solid waste management (MSWM) systems threaten waste picker livelihoods. From 2009 to 2013, a major development project, embodying traditional neoliberal policies with inclusive social policies, transformed the Managua, Nicaragua, municipal solid waste site from an open-air dump where as many as 2,000 informal waste pickers toiled to a sanitary landfill. To investigate waste pickers' social and economic condition, including labor characteristics, household income, and poverty incidence, after the project's completion, 146 semi-structured survey questionnaires were administered to four communities adjacent to the landfill and 45 semi-structured interviews were completed with key stakeholders. Findings indicate that hundreds of waste pickers were displaced by the project, employment benefits from the project were unevenly distributed by neighborhood, and informal waste picking endures due to persistent impoverishment, thereby contributing to continued social and economic marginalization and environmental degradation. The findings highlight the limitations of inclusive neoliberal development efforts to transform MSWM in a low-income country. Copyright © 2017 Elsevier Ltd. All rights reserved.

Forest degradation and deforestation affect ecosystem function and climate regulation services such as carbon storage. Historically, Central America has been a deforestation and forest degradation hotspot. Wiwili and El Cuá municipalities in northern Nicaragua are no exception, where subsistence agriculture and cattle ranch expansion have driven deforestation and other wood extraction activities, leading to various levels of forest degradation. Reduction of Emissions from forest Degradation and Deforestation (REDD) projects are proposed as a tool to slow the degradation and loss of carbon stocks by restoring carbon to its natural levels in order to mitigate carbon dioxide emissions that cause global warming. REDD projects require baseline estimations of current carbon stocks and forest degradation status. We estimated carbon stocks across a forest degradation gradient based on common biophysical variables and commercially available (RapidEye) remote sensing data. We measured 80 temporary forest plots (50x20m) for aboveground biomass to sample a gradient of forest degradation at two municipalities (El Cuá and Wiwili) in northern Nicaragua. We measured biomass in trees (≥10 cm DBH), saplings (5-9.9 cm DBH), other growth forms (ferns, palms and woody vines), and large detritus (snags and downed wood). Biomass was estimated by a range of allometric models and a constant conversion factor (0.47) was applied to calculate aboveground carbon stocks. Remote sensing data from a RapidEye scene for 02/2010 provided data for 5 spectral bands and 19 vegetation indexes at 6 m spatial resolution. Precipitation, temperature, altitude, slope, canopy cover, and aspect were also used as input variables for carbon modeling. We tested linear mixed models, generalized additive mixed models and regression tree approaches to explain carbon stocks based on vegetation indexes and biophysical variables. Additionally, we grouped plots into low (17-168 Mg C ha-1), medium (168-302 Mg C ha-1

In addition, frequent occurrence of urinary tract infections (UTI) among men and a dysuria syndrome described by sugarcane workers as "chistata" are both reported. This study examines health professionals´ perceptions regarding etiology of these conditions and their treatment approaches, including use of potentially nephrotoxic medications. Nineteen in-person semi-structured interviews were conducted in November 2010 among ten physicians and nine pharmacists practicing in the region. Health professionals perceived CKD as a serious and increasing problem in the region, primarily affecting young men working as manual laborers. All interviewees regarded occupational and environmental exposure to sun and heat, and dehydration as critical factors associated with the occurrence of CKD. These factors were also considered to play a role in the occurrence of chistata in the region. Health professionals indicated that reluctance among workers to hydrate might be influenced by perceptions of water contamination. Symptoms often were treated with non-steroidal anti-inflammatory drugs (NSAIDs), diuretics and antibiotics. Physicians acknowledged that the diagnosis of UTI usually was not based on microbial culture and opined that the use of potentially nephrotoxic medications may be contributing to CKD. Interviews provided evidence suggesting that medications such as diuretics, antibiotics and NSAIDs are widely used and sold over the counter for symptoms that may be related to dehydration and volume depletion. These factors, alone or in combination, may be possible contributors to kidney damage. Acute kidney damage coupled with volume depletion and exposures including medications and infectious agents should be further evaluated as causal factors for CKD in this region.

Cerro Negro, near León, Nicaragua is a young, relatively small basaltic cinder cone volcano that has been unusually active during its short lifespan. Multiple explosive eruptions have deposited significant amounts of ash on León and the surrounding rural communities. While a number of studies investigate the geochemistry and stress regime of the volcano, subsurface structures have only been studied by diffuse soil gas surveys. These studies have raised several questions as to the proper classification of Cerro Negro and its relation to neighboring volcanic features. To address these questions, we collected 119 gravity measurements around Cerro Negro volcano in an attempt to delineate deep structures at the volcano. The resulting complete Bouguer anomaly map revealed local positive gravity anomalies (wavelength 0.5 to 2 km, magnitude +4 mGal) and regional positive (10 km wavelength, magnitudes +10 and +8 mGal) and negative (12 and 6 km wavelength, magnitudes -18 and -13 mGal) Bouguer anomalies. Further analysis of these gravity data through inversion has revealed both local and regional density anomalies that we interpret as intrusive complexes at Cerro Negro and in the Nicaraguan Volcanic Arc. The local density anomalies at Cerro Negro have a density of 2700 kg m-3 (basalt) and are located between -250 and -2000 m above sea level. The distribution of recovered density anomalies suggests that eruptions at Cerro Negro may be tapping an interconnected magma plumbing system beneath El Hoyo, Cerro La Mula, and Cerro Negro, and more than seven other proximal volcanic features, implying that Cerro Negro should be considered the newest cone of a Cerro Negro-El Hoyo volcanic complex.

We present a comparative study of soil CO2 flux (FCO2">FCO2) measured by five groups (Groups 1–5) at the IAVCEI-CCVG Eighth Workshop on Volcanic Gases on Masaya volcano, Nicaragua. Groups 1–5 measured FCO2 using the accumulation chamber method at 5-m spacing within a 900 m2 grid during a morning (AM) period. These measurements were repeated by Groups 1–3 during an afternoon (PM) period. Measured FCO2 ranged from 218 to 14,719 g m−2 day−1. The variability of the five measurements made at each grid point ranged from ±5 to 167%. However, the arithmetic means of fluxes measured over the entire grid and associated total CO2 emission rate estimates varied between groups by only ±22%. All three groups that made PM measurements reported an 8–19% increase in total emissions over the AM results. Based on a comparison of measurements made during AM and PM times, we argue that this change is due in large part to natural temporal variability of gas flow, rather than to measurement error. In order to estimate the mean and associated CO2 emission rate of one data set and to map the spatial FCO2 distribution, we compared six geostatistical methods: arithmetic and minimum variance unbiased estimator means of uninterpolated data, and arithmetic means of data interpolated by the multiquadric radial basis function, ordinary kriging, multi-Gaussian kriging, and sequential Gaussian simulation methods. While the total CO2 emission rates estimated using the different techniques only varied by ±4.4%, the FCO2 maps showed important differences. We suggest that the sequential Gaussian simulation method yields the most realistic representation of the spatial distribution of FCO2, but a variety of geostatistical methods are appropriate to estimate the total CO2 emission rate from a study area, which is a primary goal in volcano monitoring research.

Oxygen fugacity of gases and rocks from Momotombo Volcano, Nicaragua: Application to volcanological monitoring

1988-12-01

The oxygen fugacity (fO2) and the fO2 versus T°C relationship of high-temperature (600°-860°C) gas emissions from Momotombo volcano, Nicaragua, was determined from both field electrochemical measurements (electrolytic cell assembly) and thermodynamic computations on gas samples collected between 1978 and 1985. It was then compared with the intrinsic fO2 of fresh and altered lavas from the last eruption (1905), as measured between 500° and 1100°C in laboratory. The electrochemical results show that the oxygen fugacity of Momotombo fumaroles, at equivalent temperature, is much higher than that of the fresh 1905 lava (˜FMQ buffer) and closer to that of their altered wall rocks (˜FMQ buffer). The equilibrium O2 fugacities calculated from the chemistry of gas samples confirm this pattern. However, they suggest that the gas mixtures preserve the (variable) memory of a higher thermal equilibrium achieved at depth, under temperature and fO2 conditions of up to 1050°C and 10-9.0 atm, respectively, which correspond to the cross over between the fO2-T gas and lava trends. These data thus support the idea that Momotombo volcanic gases, released in a period of increasing activity, escape from a shallow magma body before suffering a variable oxidation during their ascent through both unbuffered cooling and reactions with environmental fluids and rocks. This late oxidation is weaker at central fumaroles than at peripherical ones. While between 1978 and 1985 the temperature of the hottest fumarole increased from 750° to 865°-900°C, the equilibrium fO2 of the gas decreased by nearly one order of magnitude (at comparable equilibrium temperature). Such an evolution presumably reflects an increasing connection between the surface exhalations and the magma degassing at depth along with time. This work underlines the possibility of monitoring the processes of magma ascent and gas-magma separation within a volcano before an eruption by continuously recording the changes of

Closing the cycle on food and energy resource flows in order to create a more sustainable rural economy in Nicaragua

NASA Astrophysics Data System (ADS)

Casillas, C. E.

2009-12-01

The ecologically sustainable development of economies is often discussed at the urban scale and framed in terms of the environmental threats that accompany rapid growth. The dynamics of rural economies are less complex and provide valuable insights into how resource flows may be better utilized, as well what are the critical roles and relationships of government and society. This paper will present a case study of economic and ecologically appropriate innovations that can be made to the production and consumption behavior within a community on the Atlantic Coast of Nicaragua. Orinoco is a small Garifuna community situated on the Pearl Lagoon basin. It has a population of over 1000 people and its economy is primarily based on the exploitation of declining shrimp and fish resources. This paper will quantify the monetary and material resource flows comprising the current economy, and present technically viable alternatives that would utilize the abundant natural resources in a more ecologically sustainable manner, while decreasing the dependence on imported food and fuels. Specifically, the paper will describe how recently implemented projects of energy conservation can be coupled with improved agricultural and fishing practices in order to meet local and external market demands for fish and vegetable oil. Secondary products can be utilized to eliminate the dependence on imported liquid and gas fossil fuels for cooking and electricity generation.

2012-12-01

In Central America, approximately 12% of women report ever having been forced to have sex by an intimate male partner, and sexual violence by others is also a frequent experience. All Central American countries are signatories to human rights agreements that oblige States to ensure access to comprehensive health services for victims of sexual violence, but there is limited information as to whether these agreements have been translated into policy and practice. This article critically examines health sector guidelines for the treatment of sexual violence in El Salvador, Guatemala, Honduras and Nicaragua, and reports on an assessment of services in 34 private- and public-sector facilities in the four countries. Overall, policies were consistent with international agreements and included guidance on detection and documentation of violence, forensic examination, treatment, referral and follow-up care. However, only a small proportion of women who experience sexual violence actually seek care. The challenge facing all four countries is to turn policy into practice. Screening practices were inconsistent, and policies needed to indicate more clearly the roles and responsibilities of health care providers and forensic specialists. Finally, women's right to privacy and confidentiality in reports of cases to legal authorities needed further consideration, as well as the importance of providing all services at a single location.

2015-09-01

Cochlear implantation (CI) is a common intervention for severe-to-profound hearing loss in high-income countries, but is not commonly available to children in low resource environments. Owing in part to the device costs, CI has been assumed to be less economical than deaf education for low resource countries. The purpose of this study is to compare the cost effectiveness of the two interventions for children with severe-to-profound sensorineural hearing loss (SNHL) in a model using disability adjusted life years (DALYs). Cost estimates were derived from published data, expert opinion, and known costs of services in Nicaragua. Individual costs and lifetime DALY estimates with a 3% discounting rate were applied to both two interventions. Sensitivity analysis was implemented to evaluate the effect on the discounted cost of five key components: implant cost, audiology salary, speech therapy salary, number of children implanted per year, and device failure probability. The costs per DALY averted are $5,898 and $5,529 for CI and deaf education, respectively. Using standards set by the WHO, both interventions are cost effective. Sensitivity analysis shows that when all costs set to maximum estimates, CI is still cost effective. Using a conservative DALY analysis, both CI and deaf education are cost-effective treatment alternatives for severe-to-profound SNHL. CI intervention costs are not only influenced by the initial surgery and device costs but also by rehabilitation costs and the lifetime maintenance, device replacement, and battery costs. The major CI cost differences in this low resource setting were increased initial training and infrastructure costs, but lower medical personnel and surgery costs.

2009-01-01

Background Although reducing intimate partner violence (IPV) is a pervasive public health problem, few longitudinal studies in developing countries have assessed ways to end such abuse. To this end, this paper aims to analyze individual, family, community and societal factors that facilitate reducing IPV. Methods A longitudinal population-based study was conducted in León, Nicaragua at a demographic surveillance site. Women (n = 478) who were pregnant between 2002 and 2003 were interviewed, and 398 were found at follow-up, 2007. Partner abuse was measured using the WHO Multi-country study on women's health and domestic violence questionnaire. Women's socio demographic variables, perceived emotional distress, partner control, social resources, women's norms and attitudes towards IPV and help-seeking behaviours were also assessed. Ending of abuse was defined as having experienced any abuse in a lifetime or during pregnancy but not at follow-up. Crude and adjusted odds ratios were applied. Results Of the women exposed to lifetime or pregnancy IPV, 59% reported that their abuse ended. This finding took place in a context of a substantial shift in women's normative attitudes towards not tolerating abuse. At the family level, no or diminishing partner control [ORadj 6.7 (95%CI 3.5-13)] was associated with ending of abuse. At the societal level, high or improved social resources [ORadj 2.0 (95%CI 1.1.-3.7)] were also associated with the end of abuse. Conclusion A considerable proportion of women reported end of violence. This might be related to a favourable change in women's norms and attitudes toward gender roles and violence and a more positive attitude towards interventions from people outside their family to end abuse. Maintaining and improving social resources and decreasing partner control and isolation are key interventions to ending abuse. Abuse inquiring may also play an important role in this process and must include health care provider's training and a

Photogrammetric Analysis of Changes in Crater Morphology at Telica Volcano, Nicaragua from 1994 to 2016

NASA Astrophysics Data System (ADS)

Hanagan, C.; La Femina, P.

2017-12-01

Understanding processes that lead to volcanic eruptions is paramount for predicting future volcanic activity. Telica volcano, Nicaragua is a persistently active volcano with hundreds of daily, low magnitude and low frequency seismic events, high-temperature degassing, and sub-decadal VEI 1-3 eruptions. The phreatic vulcanian eruptions of 1999, 2011, and 2013, and phreatic to phreatomagmatic vulcanian eruption of 2015 are thought to have resulted by sealing of the hydrothermal system prior to the eruptions. Two mechanisms have been proposed for sealing of the volcanic system, hydrothermal mineralization and landslides covering the vent. These eruptions affect the crater morphology of Telica volcano, and therefore the exact mechanisms of change to the crater's form are of interest to provide data that may support or refute the proposed sealing mechanisms, improving our understanding of eruption mechanisms. We use a collection of photographs between February 1994 and May 2016 and a combination of qualitative and quantitative photogrammetry to detect the extent and type of changes in crater morphology associated with 2011, 2013, and 2015 eruptive activity. We produced dense point cloud models using Agisoft PhotoScan Professional for times with sufficient photographic coverage, including August 2011, March 2013, December 2015, March 2016, and May 2016. Our May 2016 model is georeferenced, and each other point cloud was differenced using the C2C tool in CloudCompare and the M3C2 method (CloudCompare plugin) Lague et al. (2013). Results of the qualitative observations and quantitative differencing reveal a general trend of material subtraction from the inner crater walls associated with eruptive activity and accumulation of material on the crater floor, often visibly sourced from the walls of the crater. Both daily activity and VEI 1-3 explosive events changed the crater morphology, and correlation between a landslide-covered vent and the 2011 and 2015 eruptive sequences

Soil-transmitted helminths are intestinal nematodes that can infect all members of a population but specially school-age children living in poverty. Infection can be significantly reversed with anthelmintic drug treatments and sanitation improvement. Implementation of effective public health programs requires reliable and updated information to identify areas at higher risk and to calculate amount of drug required. Geo-referenced in situ prevalence data will be overlaid over an ecological map derived from RS data using ARC Map 9.3 (ESRI). Prevalence data and RS data matching at the same geographical location will be analyzed for correlation and those variables from RS data that better correlate with prevalence will be included in a multivariate regression model. Temperature, vegetation, and distance to bodies of water will be inferred using data from Moderate-Resolution Imaging Spectroradiometer (MODIS) and Landsat TM and ETM+. Elevation will be estimated with data from The Shuttle Radar Topography Mission (SRTM). Prevalence and intensity of infections are determined by parasitological survey (Kato Katz) of children enrolled in rural schools in Boaco, Nicaragua, in the communities of El Roblar, Cumaica Norte, Malacatoya 1, and Malacatoya 2). This study will demonstrate the importance of an integrated GIS/RS approach to define sampling clusters without the need for any ground-based survey. Such information is invaluable to identify areas of high risk and to geographically target control programs that maximize cost-effectiveness and sanitation efforts.

Upper Paleogene shallow-water events in the Sandino Forearc Basin, Nicaragua-Costa Rica - response to tectonic uplift

Andjic, Goran; Baumgartner-Mora, Claudia; Baumgartner, Peter O.

2016-04-01

The Upper Cretaceous-Neogene Sandino Forearc Basin is exposed in the southeastern Nicaraguan Isthmus and in the northwestern corner of Costa Rica. It consists of an elongated, slightly folded belt (160 km long/30 km wide). During Campanian to Oligocene, the predominantly deep-water pelagic, hemipelagic and turbiditic sequences were successively replaced by shelf siliciclastics and carbonates at different steps of the basin evolution. We have made an inventory of Tertiary shallow-water limestones in several areas of Nicaragua and northern Costa Rica. They always appear as isolated rock bodies, generally having an unconformable stratigraphic contact with the underlying detrital sequences. The presence of these short-lived carbonate shoals can be attributed to local or regional tectonic uplift in the forearc area. The best-preserved exposure of such a carbonate buildup is located on the small Isla Juanilla (0.15 km2, Junquillal Bay, NW Costa Rica). The whole island is made of reef carbonates, displaying corals in growth position, associated with coralline red algae (Juanilla Formation). Beds rich in Larger Benthic Foraminifera such as Lepidocyclina undosa -favosa group permit to date this reef as late Oligocene. A first uplift event affected the Nicaraguan Isthmus, that rose from deep-water to shelfal settings in the latest Eocene-earliest Oligocene. The upper Oligocene Juanilla Formation formed on an anticline that developed during the early Oligocene, contemporaneously with other folds observed in the offshore Sandino Forearc Basin. During the early Oligocene, a period of global sea-level fall, the folded tectonic high underwent deep erosion. During the late Oligocene, a time of overall stable eustatic sea level, tectonic uplift gave way to moderate subsidence, creating accommodation space for reef growth. A 4th or 5th order (Milankovic-type) glacio-eustatic sea level rise, could also have triggered reef growth, but its preservation implies at least moderate

Geochemistry and volatile content of magmas feeding explosive eruptions at Telica volcano (Nicaragua)

Telica volcano, in north-west Nicaragua, is a young stratovolcano of intermediate magma composition producing frequent Vulcanian to phreatic explosive eruptions. The Telica stratigraphic record also includes examples of (pre)historic sub-Plinian activity. To refine our knowledge of this very active volcano, we analyzed major element composition and volatile content of melt inclusions from some stratigraphically significant Telica tephra deposits. These include: (1) the Scoria Telica Superior (STS) deposit (2000 to 200 years Before Present; Volcanic Explosive Index, VEI, of 2-3) and (2) pyroclasts from the post-1970s eruptive cycle (1982; 2011). Based on measurements with nanoscale secondary ion mass spectrometry, olivine-hosted (forsterite [Fo] > 80) glass inclusions fall into 2 distinct clusters: a group of H2O-rich (1.8-5.2 wt%) inclusions, similar to those of nearby Cerro Negro volcano, and a second group of CO2-rich (360-1700 μg/g CO2) inclusions (Nejapa, Granada). Model calculations show that CO2 dominates the equilibrium magmatic vapor phase in the majority of the primitive inclusions (XCO2 > 0.62-0.95). CO2, sulfur (generally < 2000 μg/g) and H2O are lost to the vapor phase during deep decompression (P > 400 MPa) and early crystallization of magmas. Chlorine exhibits a wide concentration range (400-2300 μg/g) in primitive olivine-entrapped melts (likely suggesting variable source heterogeneity) and is typically enriched in the most differentiated melts (1000-3000 μg/g). Primitive, volatile-rich olivine-hosted melt inclusions (entrapment pressures, 5-15 km depth) are exclusively found in the largest-scale Telica eruptions (exemplified by STS in our study). These eruptions are thus tentatively explained as due to injection of deep CO2-rich mafic magma into the shallow crustal plumbing system. More recent (post-1970), milder (VEI 1-2) eruptions, instead, do only exhibit evidence for low-pressure (P < 50-60 MPa), volatile-poor (H2O < 0.3-1.7 wt%; CO2 < 23

Whereas natural disasters more commonly occur in low-income countries, almost all studies on psychological consequences have been conducted in the Western world. In countries where resources are poor it is of importance to know which groups should be targeted for early intervention after a disaster. The study aims at assessing the prevalence of post-traumatic stress disorder PTSD and of post-traumatic symptoms among people afflicted by hurricane Mitch in Nicaragua and at identifying risk factors for PTSD symptoms 6 months following a disaster. At four primary health care centres, 496 consecutive adult patients were interviewed 6 months after hurricane Mitch regarding PTSD symptoms (Harvard Trauma Questionnaire, HTQ), disaster experiences and post-disaster help-seeking. All individuals resident in the area during Mitch were judged to have experienced a trauma fulfilling A criteria for PTSD. Regarding more specific traumas, 39% reported a close relative to be dead or seriously injured and 72% had their house partly or completely destroyed. Prevalence of PTSD ranged from 9.0% in the worst afflicted area to 4.5% in a less damaged area. From a dimensional perspective, PTSD symptoms according to HTQ 6 months after the disaster were significantly associated with the death of a relative (beta-coefficient 0.257, P = 0.000), a house destroyed (beta-coefficient 0.148, P = 0.001), female sex (beta-coefficient 0.139, P = 0.001), previous mental health problems (beta-coefficient 0.109, P = 0.009) and illiteracy (beta-coefficient 0.110, P = 0.009). Those with previous mental health problems (OR = 4.84; 95% CI = 3.04-7.66) were more likely than others to seek from help, any source whereas the opposite was true for illiterate people (OR = 0.38; 95% CI = 0.21-0.69). Of all respondents, 8.5% reported that they had thought of taking their lives, and illiterates (OR 2.84; 95% CI = 1.12-4.37) and those with previous mental health problems (OR 2.84; 95% CI = 1.12-4.57) were at particular

Appropriate feeding behaviours are important for child growth and development. In societies undergoing nutrition transition, new food items are introduced that may be unfavourable for child health. Set in rural Nicaragua, the aim of this study was to describe the infant and young child feeding (IYCF) practices as well as the consumption of highly processed snack foods (HP snacks) and sugar-sweetened beverages (SSBs). All households with at least one child 0- to 35-month-old (n = 1371) were visited to collect information on current IYCF practices in the youngest child as well as consumption of SSBs and HP snacks. Breastfeeding was dominant (98%) among 0- to 1-month-olds and continued to be prevalent (60%) in the second year, while only 34% of the 0- to 5-month-olds were exclusively breastfed. Complementary feeding practices were deemed acceptable for only 59% of the 6- to 11-month-old infants, with low dietary diversity reported for 50% and inadequate meal frequency reported for 30%. Consumption of HP snacks and SSBs was frequent and started early; among 6- to 8-month-olds, 42% and 32% had consumed HP snacks and SSBs, respectively. The difference between the observed IYCF behaviours and World Health Organization recommendations raises concern of increased risk of infections and insufficient intake of micronutrients that may impair linear growth. The concurrent high consumption of SSBs and HP snacks may increase the risk of displacing the recommended feeding behaviours. To promote immediate and long-term health, growth and development, there is a need to both promote recommended IYCF practices as well as discourage unfavourable feeding behaviours. © 2014 John Wiley & Sons Ltd.

Thermal Models of the Costa Rica - Nicaragua Subduction Zone: the Effect of a Three-Dimensional Oceanic Plate Structure and Hydrothermal Circulation in the Temperature Distribution and Mantle Wedge Dynamics

NASA Astrophysics Data System (ADS)

Rosas, J. C.; Currie, C. A.; He, J.

2014-12-01

Over the last years several 2D thermo-mechanical models of the Costa Rica - Nicaragua Subduction Zone (CNSZ) have studied the thermal distribution of sections of the fault. Such investigations allow us to understand temperature-related aspects of subduction zones, like volcanism and megathrust earthquake locations. However, certain features of the CNSZ limit the range of applicability of 2D models. In the CNSZ, geochemical trends and seismic anisotropy studies reveal a 3D mantle wedge flow that departs from the 2D corner flow. The origin of this flow are dip variations (20o to 25o between Nicaragua and Costa Rica) and the presence of a slab window in Panama that allows material to flow into the mantle wedge. Also, the Central America trench has abrupt variations in surface heat flux that contrasts with steady changes in plate age and convergence rate. These variations have been attributed to hydrothermal circulation (HC), which effectively removes heat from the oceanic crust.In this project we analyze the thermal structure of the CNSZ. The objective is to study dehydration and metamorphic reactions, as well as the length of the megathrust seismogenic zone. We created 3D finite-element models that employ a dislocation creep rheology for the mantle wedge. Two aspects make our models different from previous studies: an up-to-date 3D slab geometry, and an implementation of HC by introducing a conductive proxy in the subducting aquifer, allowing us to model convective heat transport without the complex, high-Rayleigh number calculations. A 3D oceanic boundary condition that resembles the along-strike changes in surface heat flux is also employed. Results show a maximum mantle wedge flow rate of 4.69 cm/yr in the along-strike direction, representing more than 50% of the slab convergence rate. With respect to 2D models, analysis shows this flow changes temperatures by ~100 C in the mantle wedge near areas of strong slab curvature. Along the subducting interface, there is

Large earthquakes, such as the Mw 7.7 1992 Nicaragua earthquake, have occurred off the Pacific coasts of El Salvador and Nicaragua in Central America and have generated distractive tsunamis along these coasts. It is necessary to determine appropriate fault models before large tsunamis hit the coast. In this study, first, fault parameters were estimated from the W-phase inversion, and then an appropriate fault model was determined from the fault parameters and scaling relationships with a depth dependent rigidity. The method was tested for four large earthquakes, the 1992 Nicaragua tsunami earthquake (Mw7.7), the 2001 El Salvador earthquake (Mw7.7), the 2004 El Astillero earthquake (Mw7.0), and the 2012 El Salvador-Nicaragua earthquake (Mw7.3), which occurred off El Salvador and Nicaragua in Central America. The tsunami numerical simulations were carried out from the determined fault models. We found that the observed tsunami heights, run-up heights, and inundation areas were reasonably well explained by the computed ones. Therefore, our method for tsunami early warning purpose should work to estimate a fault model which reproduces tsunami heights near the coast of El Salvador and Nicaragua due to large earthquakes in the subduction zone.

Low-pressure differentiation of tholeiitic lavas as recorded in segregation veins from Reykjanes (Iceland), Lanzarote (Canary Islands) and Masaya (Nicaragua)

Martin, E.; Sigmarsson, O.

Segregation veins are common in lava sheets and result from internal differentiation during lava emplacement and degassing. They consist of evolved liquid, most likely replaced by gas-filter pressing from a ˜50% crystallised host lava. Pairs of samples, host lavas and associated segregation veins from the Reykjanes Peninsula (Iceland), Lanzarote (Canary Islands) and the Masaya volcano (Nicaragua) show extreme mineralogical and compositional variations (MgO in host lava, segregation veins and interstitial glass ranges from 8-10 wt%, 3-6 wt%, and to less than 0.01 wt%, respectively). These samples allow the assessment of the internal lava flow differentiation mechanism, since both the parental and derived liquid are known in addition to the last magma drops in the form of late interstitial glasses. The mineralogical variation, mass-balance calculated from major- and trace element composition, and transitional metal partition between crystals and melts are all consistent with fractional crystallisation as the dominant differentiation mechanism. The interstitial glasses are highly silicic (SiO2 = 70-80 wt%) and represent a final product of high-degree (75-97%) fractional crystallisation of olivine tholeiite at a pressure close to one atmosphere. The tholeiitic liquid-line-of-decent and the composition of the residual melts are governed by the K2O/Na2O of the initial basaltic magma. The granitic minimum is reached if the initial liquid has a high K2O/Na2O whereas trondhjemitic composition is the final product of magma with low initial K2O/Na2O.

Smallholder Food and Water Security in the Face of Climatic Stress and the Coffee Leaf Rust: Lessons from Nicaragua

Smallholder farmers in Nicaragua and throughout much of Central America preserve forest biodiversity and contribute to the sustainable production of coffee and other crops while, paradoxically, they themselves must cope with recurring periods of seasonal hunger. Smallholder food and water security in the region is affected by hurricanes, periodic drought events, climatic changes, an on-going outbreak of the coffee leaf rust, and fluctuations in food prices. Using regression analysis, our research examines what factors strengthened resilience to these hazards at the household level over the 1981 - 2014 time period. To this end, we integrate qualitative research on coping responses and local institutions, a participatory survey of 368 households, and an analysis of hydro-climatic data. Our results indicate that coping responses to the coffee leaf rust outbreak and the 2014 drought are comparable in severity to those used to endure Hurricane Mitch in 1998, and a severe 2009 drought. Higher smallholder resilience to stresses affecting food and water security is associated with larger farms, off-farm employment, more on-farm food production, higher numbers of fruit trees, and greater coffee harvests. Households that reported more severe coping responses to hazards earlier in the study period tended to be more strongly impacted by later hazards and reported generally greater seasonal hunger. Affiliation with local farmer-to-farmer institutions prioritizing either subsistence-oriented production or sales to international fair-trade markets did not correlate strongly with coping responses; however, subsistence-oriented institutions promote several resilience-enhancing practices. Lessons learned by adapting to past hazards may be used to develop adaptation and mitigation strategies for smallholders under continued climate variability and change.

A Simple Approach To Mass Movement Hazard Evaluation In Developing Countries: Example From NW Nicaragua.

NASA Astrophysics Data System (ADS)

Pallàs, R.; Vilaplana, J. M.; Guinau, M.; Falgàs, E.; Alemany, X.; Muñoz, A.

Current trends in landslide hazard assessment involve a complex combination of methodologies. In spite of being the most vulnerable and in need of mitigation poli- cies, developing countries lack the general socioeconomic structures and technical facilities for such complex approaches to be implemented. The main difficulties com- monly encountered in those countries are the scarcity of previous topographic, geo- logical, geotechnical, historical and instrumental data, and the unavailability of aerial- photo coverages at suitable times and scales. In consequence, there is a strong need for developing simple methodologies of landslide hazard assessment and mitigation, which can be readily tested and implemented by developing countries themselves. To explore this line of research, we selected an area of about 20 square km severely hit by Hurricane Mitch, at the Departamento de Chinandega (NW Nicaragua). The abun- dant mass movements (mainly debris flows) produced during the Mitch rainfall event were investigated through aerial photographs at 1:60.000 scale (flight of December 1998), while much less conspicuous pre-Mich landslides were detected on 1:40.000 aerial photographs (1996 flight). We mapped over one hundred mass movements at 1:10.000 scale in the field, and recorded information concerning regolith composi- tion and thickness, mass movement dimensions and volumes, failure angle (around 22 degrees) and land use for each movement. We realised that, due to the extreme fragility of antropic structures found in the area, any mass movement is highly destructive whatever its magnitude. On the other hand, we found an almost complete lack of data concerning frequency of landsliding. Thus, the concepts of magnitude and frequency commonly used for hazard evaluation pur- poses were of little help in this case. With these considerations in mind, we found that hazard evaluation and zoning could be approached by combining two main concepts: (1) the observed degree of slope

Evolution of the Northern Nicaragua Rise during the Oligocene Miocene: Drowning by environmental factors

NASA Astrophysics Data System (ADS)

Mutti, Maria; Droxler, André W.; Cunningham, Andrew D.

2005-04-01

Possible causes to explain platform drowning have been hotly debated by carbonate sedimentologists for more than a decade now. In this paper, we present multiple evidence to explain the drowning of a carbonate megabank that covered most of the modern Northern Nicaragua Rise (NNR) during an interval spanning from late Oligocene to early Miocene by the interaction of several environmental factors. The recovery during ODP Leg 165 of late Oligocene to middle Miocene sedimentary sequences in the sub-seafloor of the modern channels and basin, Pedro Channel and Walton Basin, respectively, that dissect the NNR (Site 1000) and south of the rise in the Colombian Basin (Site 999), combined with information from dredged rock samples, allows us to explore in more detail the timing and possible mechanisms responsible for the drowning of the megabank and its relationship to Miocene climate change. The modern system of isolated banks and shelves dissected by a series of intervening seaways and basins on the NNR has evolved from a continuous, shallow-water carbonate “megabank” that extended from the Honduras/Nicaraguan mainland to the modern island of Jamaica. Available information suggests that this megabank broke apart and partially drowned in the late part of the late Oligocene at around 27 Ma and finally foundered during the late early Miocene around 20 Ma, resulting in limited neritic coral growth in the areas where the modern isolated carbonate banks and shelves are occurring today. Available information also suggests that the southern and central parts of Pedro Channel were already a deep-water area before the major episode of platform drowning, and its formation predates the initiation of the Caribbean Current. However, after the partial drowning of the megabank, the channel has become a major pathway for the Caribbean Current. Stratigraphic units identified in deep-water carbonates sampled at ODP Sites 999 and 1000 help to constrain the environmental setting leading to

The 12.4 ka Upper Apoyeque Tephra, Nicaragua: stratigraphy, dispersal, composition, magma reservoir conditions and trigger of the plinian eruption

Upper Apoyeque Tephra (UAq) was formed by a rhyodacitic plinian eruption in west-central Nicaragua at 12.4 ka BP. The fallout tephra was dispersed from a progressively rising plinian eruption column that became exposed to different wind speeds and directions at different heights in the stratosphere, leading to an asymmetric tephra fan with different facies in the western and southern sector. Tephra dispersal data integrated with geochemical compositions of lava flows in the area facilitate delimitation of the source vent to the south of Chiltepe Peninsula. UAq, Lower Apoyeque Tephra, Apoyeque Ignimbrite, and two lava lithic clasts in San Isidro Tephra together form a differentiation trend distinct from that of the younger tephras and lavas at Chiltepe Volcanic Complex in a TiO2 versus K2O diagram, compositionally precluding a genetic relationship of UAq with the present-day Apoyeque stratovolcano. Apoyeque Volcano in its present shape did not exist at the time of the UAq eruption. The surface expression of the UAq vent is now obscured by younger eruption products and lake water. Pressure-temperature constraints based on mineral-melt equilibria and fluid inclusions in plagioclase indicate at least two magma storage levels. Clinopyroxenes crystallised in a deep crustal reservoir at ˜24 km depth as inferred from clinopyroxene-melt inclusion pairs. Chemical disequilibrium between clinopyroxenes and matrix glasses indicates rapid magma ascent to the shallower reservoir at ˜5.4 km depth, where magnesiohornblendes and plagioclase fractionated at a temperature of ˜830 °C. Water concentrations were ˜5.5 wt.% as derived from congruent results of amphibole and plagioclase-melt hygrometry. The eruption was triggered by injection of a hotter, more primitive melt into a water-supersaturated reservoir.

Highly-explosive plinian eruptions belong to the most devastating phenomena of volcanic activity. Upper Apoyeque Tephra (UAq), erupted in close vicinity of the Managua city region in west-central Nicaragua with two million inhabitants, was formed by a rhyodacitic plinian eruption at 12.4 ka BP. The fallout tephra was dispersed from a progressively rising plinian eruption column that became exposed to different wind speeds and directions at different heights in the stratosphere, leading to an asymmetric tephra fan with different facies in the western and southern sector. Tephra dispersal data integrated with geochemical compositions of lava flows in the area facilitate to delimit the source vent to the south of Chiltepe Peninsula.

The eruption was triggered through injection of a hotter, more primitive melt into a water-supersaturated reservoir.

The HLA system shows the most extensive polymorphism in the human genome. Allelic and haplotypic frequencies of HLA genes vary dramatically across human populations. Due to a complex history of migration, populations in Latin America show a broad variety of admixture proportions, usually varying not only between countries, but also within countries. Knowledge of HLA allele and haplotype frequencies is essential for medical fields such as transplantation, but also serves as a means to assess genetic diversity and ancestry in human populations. Here, we have determined high-resolution HLA-A, -B, -C, and -DRB1 allele and haplotype frequencies in a sample of 713 healthy subjects from three Mestizo populations, one population of African descent, and Amerindians of five different groups from Costa Rica and Nicaragua and compared their profiles to a large set of indigenous populations from Iberia, Sub-Saharan Africa, and the Americas. Our results show a great degree of allelic and haplotypic diversity within and across these populations, with most extended haplotypes being private. Mestizo populations show alleles and haplotypes of putative European, Amerindian, and Sub-Saharan African origin, albeit with differential proportions. Despite some degree of gene flow, Amerindians and Afro-descendants show great similarity to other Amerindian and West African populations, respectively. This is the first comprehensive study reporting high-resolution HLA diversity in Central America, and its results will shed light into the genetic history of this region while also supporting the development of medical programs for organ and stem cell transplantation. © 2018 John Wiley & Sons A/S.

Atmospheric dispersion, environmental effects and potential health hazard associated with the low-altitude gas plume of Masaya volcano, Nicaragua

NASA Astrophysics Data System (ADS)

Delmelle, P.; Stix, J.; Baxter, P.; Garcia-Alvarez, J.; Barquero, J.

2002-09-01

Masaya volcano (560 m a.s.l.), Nicaragua, resumed its degassing activity in mid-1993 with the continuous emission of SO2 at rates increasing from 600 metric tons (t) day-1 (7.0 kg s-1) in 1995 to 1800 t day-1 (21.0 kg s-1) in 1999. The low-altitude gas plume is typically blown westward by the prevailing wind across the Masaya caldera and Las Sierras highlands, which are at a higher elevation than the gas vent. In this study, the areal distribution of atmospheric SO2 concentrations was monitored within 44 km of the vent with a network of passive samplers. Measured SO2 air concentrations ranged from <2 to 90 ppbv in 1998 and from <2 to 230 ppbv in 1999. The data suggest that the volcanic emissions influenced air quality across a 1,250-km2 area downwind. Local topography exerts a strong control on plume dispersal, and hilltops are particularly prone to fumigation and thus, to high ambient SO2 levels. In a zone 22 km2 in size located within 15 km of the source, the response of vegetation to sustained exposure to high atmospheric dose of volcanic SO2 and HF resulted in a strong reduction in the number of plant communities. A transition zone of somewhat indefinite boundary surrounds the devastated zones and exhibits vegetation damage in the form of leaf injury. In addition to the environmental impacts of the volcanic emissions, both short- and long-term public health hazards may exist in areas most exposed to the plume. The harmful effects of the volcanic emissions on cultivated vegetation could be diminished by using windbreaks made of gas-tolerant trees and shrubs such as Eugenia jambos, Brosimum utile and Clusia rosea. The current gas crisis at Masaya volcano provides an unique opportunity for investigating the atmospheric, environmental and medical impacts of volcanic gases and aerosols.

Identification of a Latin American-specific BabA adhesin variant through whole genome sequencing of Helicobacter pylori patient isolates from Nicaragua

In this study, Helicobacter pylori (H. pylori) is one of the most common bacterial infections in humans and this infection can lead to gastric ulcers and gastric cancer. H. pylori is one of the most genetically variable human pathogens and the ability of the bacterium to bind to the host epithelium as well as the presence of different virulence factors and genetic variants within these genes have been associated with disease severity. Nicaragua has particularly high gastric cancer incidence and we therefore studied Nicaraguan clinical H. pylori isolates for factors that could contribute to cancer risk. The complete genomes ofmore » fifty-two Nicaraguan H. pylorii isolates were sequenced and assembled de novo, and phylogenetic and virulence factor analyses were performed. The Nicaraguan isolates showed phylogenetic relationship with West African isolates in whole-genome sequence comparisons and with Western and urban South-and Central American isolates using MLSA (Multi-locus sequence analysis). A majority, 77 % of the isolates carried the cancer-associated virulence gene cagA and also the s1/i1/m1 vacuolating cytotoxin, vacA allele combination, which is linked to increased severity of disease. Specifically, we also found that Nicaraguan isolates have a blood group-binding adhesin (BabA) variant highly similar to previously reported BabA sequences from Latin America, including from isolates belonging to other phylogenetic groups. These BabA sequences were found to be under positive selection at several amino acid positions that differed from the global collection of isolates. In conclusion, the discovery of a Latin American BabA variant, independent of overall phylogenetic background, suggests hitherto unknown host or environmental factors within the Latin American population giving H. pylori isolates carrying this adhesin variant a selective advantage, which could affect pathogenesis and risk for sequelae through specific adherence properties.« less

The study analyzed differences in the risk of experiencing stressful life events (SLE) according to cultural factors, the level of economic development of the region inhabited, and gender. Information was gathered on the number and nature of SLE experienced by a sample of 604 undergraduates from 3 regions with very different levels of economic development: Madrid (Spain), León (Nicaragua), and Bilwi (Nicaragua). The results indicated a greater risk of experiencing SLE among undergraduates from Nicaragua, but few differences attributed to the undergraduates' gender or the level of economic development in the region they inhabit within the same country.

How is shrimp aquaculture transforming coastal livelihoods and lagoons in Estero Real, Nicaragua? The need to integrate social-ecological research and ecosystem-based approaches.

PubMed

Benessaiah, Karina; Sengupta, Raja

2014-08-01

Ecosystem-based approaches to aquaculture integrate environmental concerns into planning. Social-ecological systems research can improve this approach by explicitly relating ecological and social dynamics of change at multiple scales. Doing so requires not only addressing direct effects of aquaculture but also considering indirect factors such as changes in livelihood strategies, governance dynamics, and power relations. We selected the community of Puerto Morazán, Nicaragua as a case study to demonstrate how the introduction of small-scale aquaculture radically transformed another key livelihood activity, lagoon shrimp fishing, and the effects that these changes have had on lagoons and the people that depend on them. We find that shrimp aquaculture played a key role in the collapse, in the 1990s, of an existing lagoon common-property management. Shrimp aquaculture-related capital enabled the adoption of a new fishing technique that not only degraded lagoons but also led to their gradual privatization. The existence of social ties between small-scale shrimp farmers and other community members mitigated the impacts of privatization, illustrating the importance of social capital. Since 2008, community members are seeking to communally manage the lagoons once again, in response to degraded environmental conditions and a consolidation of the shrimp industry at the expense of smaller actors. This research shows that shrimp aquaculture intersects with a complex set of drivers, affecting not only how ecosystems are managed but also how they are perceived and valued. Understanding these social-ecological dynamics is essential to implement realistic policies and management of mangrove ecosystems and address the needs of resource-dependent people.

Rural electrification, climate change, and local economies: Facilitating communication in development policy and practice on Nicaragua's Atlantic Coast

NASA Astrophysics Data System (ADS)

Casillas, Christian E.

I explore the role of information and communication in the world of institution-led development. Through a series of case studies from the Atlantic Coast of Nicaragua, I present several projects and their implications for uncovering information that may lead to greater local benefit from externally-planned development projects. In order to construct policies and implement projects, development institutions collect, analyze, and simplify information, collapsing messy physical and social realities into narrow sets of metrics. In addition, local stakeholders often aren't privy to the analysis and assumptions of the "expert" planners. An evolved set of methods for dialogue and planning, which focus on sharing available information, can help facilitate outcomes that are more beneficial for targeted groups. Carbon abatement cost curves provide a clear example where the relations of complex social, economic, and environmental systems are reduced to a narrow set of metrics, specifically the cost of carbon mitigation and the total tons reduced. When the carbon abatement cost curve is applied to the community level, it reveals information and allows for conclusions obscured by aggregated national level studies. I show that there are opportunities for augmenting the limited metrics of these cost curves to include those that relate to welfare, beginning to highlight how costs and savings are distributed among stakeholders. In particular, the benefits to the most marginalized groups are heavily dependent on planners taking a pro-poor approach. However, planners typically remain blind to the priorities, capabilities, and values of the target stakeholders. There is a dearth of methods that effectively open up the development expert's black box of project designs, allowing their proposed solutions to be transparent to the target beneficiaries. I address this challenge through the presentation of a participatory modeling process that was utilized with groups of artisanal fishers

Several types of intestinal nematodes, that can infect humans and specially school-age children living in poverty, develop part of their life cycle in soil. Presence and survival of these parasites in the soil depend on given environmental characteristics like temperature and moisture that can be inferred with remote sensing (RS) technology. Prevalence of diseases caused by these parasitic worms can be controlled and even eradicated with anthelmintic drug treatments and sanitation improvement. Reliable and updated identification of geographic areas at risk is required to implement effective public health programs; to calculate amount of drug required and to distribute funding for sanitation projects. RS technology and geographical information systems (GIS) will be used to analyze for associations between in situ prevalence and remotely sensed data in order to establish RS proxies of environmental parameters that indicate the presence of these parasits. In situ data on helminthisasis will be overlaid over an ecological map derived from RS data using ARC Map 9.3 (ESRI). Temperature, vegetation, and distance to bodies of water will be inferred using data from Moderate-Resolution Imaging Spectroradiometer (MODIS) and Landsat TM and ETM+. Elevation will be estimated with data from The Shuttle Radar Topography Mission (SRTM). Prevalence and intensity of infections are determined by parasitological survey (Kato Katz) of children enrolled in rural schools in Boaco, Nicaragua, in the communities of El Roblar, Cumaica Norte, Malacatoya 1, and Malacatoya 2). This study will demonstrate the importance of an integrated GIS/RS approach to define clusters and areas at risk. Such information will help to the implementation of time and cost efficient control programs and sanitation efforts.

Objectives To assess differences in the prevalence and incidence of low back pain (LBP) and associated disability among office workers in Costa Rica, Nicaragua and Spain. Methods Data were collected at baseline (n=947, 93% response) in November 2007 and at follow-up after 12 months (n=853, 90% response). Six outcome measures were examined: baseline prevalence of (1) LBP in past 12 months, (2) LBP in past month, and (3) disabling LBP in past month; and at follow-up: (4) incidence of new LBP in the past month, (5) new disabling LBP, and (6) persistent LBP. Differences in prevalence by country were characterized by odd ratios (ORs) with 95% confidence intervals (95%CIs), before and after adjustment for covariates. Results Prevalence of LBP in the past month among office employees in Costa Rica (46.0%) and Nicaragua (44.2%) was higher than in Spain (33.6%). Incidence of new LBP was 37.0% in Nicaragua (OR=2.49; 95% CI: 1.57-3.95), 14.9% in Costa Rica (OR=0.74; 95% CI: 0.41-1.34), and 19.0% in Spain (reference). Incidence of new disabling LBP was higher in Nicaragua, 17.2% (OR=2.49; 95% CI: 1.43-4.34) and Costa Rica, 13.6% (OR=1.89; 95% CI: 1.03-3.48) than Spain (7.7%), while persistence of LBP was higher only in Nicaragua. Conclusions Prevalence of LBP and disabling LBP was higher in Costa Rican and Nicaraguan office workers than in Spain, but incidence was higher mainly in Nicaragua. Measured sociodemographic, job-related and health-related variables only partly explained the differences between countries, and further research is needed to explore reasons for the remaining differences.

Models of Metabolic Community Structure in Martian Habitable Environments: Constraints from a Terrestrial Analog Acid-Sulfate Fumarole Environment, Cerro Negro Volcano, Nicaragua

NASA Astrophysics Data System (ADS)

Rogers, K. L.; McCollom, T. M.; Hynek, B. M.

2014-12-01

Microbial habitability in extreme environments on Earth is described by microscale geochemical conditions that constrain metabolic niches in concert with long-term habitat stability that is governed by dynamic geologic processes. Using terrestrial analogs to identify habitable martian environments requires correlating microscale geochemical constraints with reconstructions of past martian environments that are based on global-scale observations. While past martian environments can be characterized by primary parameters (e.g. pH, redox, mineralogy, thermal history), microbial habitability on Earth is a complex function of both primary and derived parameters (e.g. metabolic reaction energetics, chemical & thermal gradients, flow dynamics). In recent years we have been investigating acid-sulfate fumaroles at the Mars analog site, Cerro Negro Volcano, Nicaragua, where habitability is constrained by steep thermal gradients, spatially- and temporally-variable vent dynamics, and limited water and nutrient availability. The most common niche identified thus far is found in fumaroles that host mixed photosynthetic and chemosynthetic endolithic microbial communities. One such endolith is dominated by acidic red algae (Cyanidiales), aerobic bacterial heterotrophs (Ktedonobacteria), and archaeal thermoacidophiles (Hyperthermus, Caldisphaera, and Thermofilum). An analysis of the metabolic structure suggests that primary production by the red algae supports the growth of heterotrophic thermoacidophiles. Diversification among the chemoheterotrophs with respect to temperature and oxygen tolerance suggests community adaptation to environmental gradients or variable venting dynamics. Furthermore, individual cells within the endolith are silica-encrusted, providing the possibility for biosignature formation and preservation. Putative hydrothermal environments on early Mars with similar conditions could have supported endolithic communities with comparable metabolic strategies. Even

Poor mental health among those living in poverty is a serious global public health concern. Food insecurity (FI) is recognized as an important, yet critically understudied social determinant of mental health. The relationship between FI and mothers' mental health in low- and middle-income countries (LMIC) is especially important to understand considering the high rates of poverty and associated FI in these settings. For these mothers, social support may serve as a buffer in ameliorating the impact of FI on mental distress. However, data required to understand these relationships in LMIC remain sparse. To address this gap we used quantitative and qualitative data and convergence parallel analysis to assess: the association between FI and maternal mental distress; and, whether three forms of social support - mother's general social network support and family support (spouse/partner living in the home, parents/in-laws living in the home) - moderated the association. A survey that included data on FI (ELCSA) and mental distress (SRQ-20) was administered to a population-based sample of mothers in León, Nicaragua (n = 434) in 2012. The survey was complemented by data from 6 focus groups. Regression models identified a strong positive relationship between household-level FI and maternal distress. Evidence of social support moderation was mixed: while maternal social network and spousal/partner support did not moderate this relationship, parental support did. Our ethnographic data revealed three themes that help explain these findings: FI is embarrassing/shameful, close family is the most appropriate source of social support and, fear of gossip and ridicule limit the buffering capacity of the social support network. Our findings contribute to a growing literature demonstrating that FI is an important social determinant of maternal mental distress in LMIC; and that some forms of social support may reduce (but not eliminate) the impact of FI on mental distress.

Controls on reef development and the terrigenous-carbonate interface on a shallow shelf, Nicaragua (Central America)

Marine geology and physical oceanographic data collected during two field projects (˜4 months) on the Caribbean shelf of Nicaragua indicate a surprising dominance of carbonate deposition and reef growth on a shelf that is receiving an abnormally large volume of terrigenous sediments. High rainfall rates (˜400 500 cm/year), coupled with a warm tropical climate, encourage rapid denudation of the country's central volcanic highland and transport of large volumes of terrigenous sediment and fresh water to the coast. Estimates suggest that three times more fresh water and fifteen times more sediment are introduced per unit length of coastline than on the east coast of the United States. Distribution of the terrigenous facies, development of carbonate sediment suites, and the location and quality of viable reefs are strongly controlled by the dynamic interaction near the coasts of highly turbid fresh to brackish water effluents from thirteen rivers with clear marine waters of the shelf. Oceanic water from the central Caribbean drift current intersects the shelf and moves slowely in a dominant northwest direction toward the Yucatan Channel. A sluggish secondary gyre moves to the south toward Costa Rica. In contrast, the turbid coastal water is deflected to the south in response to density gradients, surface water slopes, and momentum supplied by the steady northeast trade winds. A distinct two-layered flow is commonly present in the sediment-rich coastal boundary zone, which is typically 10 20 km wide. The low-salinity upper layer is frictionally uncoupled from the ambient shelf water and therefore can expand out of the normally coherent coastal boundary zone during periods of abnormal flooding or times when instability is introduced into the northeast trades. Reef distribution, abruptness of the terrigenous-carbonate interface, and general shelf morphology reflect the long-term dynamic structure of the shelf waters.

In the course of two trips to Central America (June 1967 and JulyAugust 1976) I had the opportunity of collecting topotypic specimens of Planorbis nicaraguanus Morelet, 1849, anatomically defined in this paper, and of P. yzabalensis Crosse & Fischer, 1879, the identity of the latter with Drepanotrema anatinum (Orbigny, 1835) is confirmed. The following planorbid species were also found: Helisoma trivolvis (Say, 1817) in Nicaragua, Guatemala, Costa Rica and Belize; H. duryi (Wetherby, 1879) in Costa Rica; Biomphalaria helophila (Orbigny, 1835) in Guatemala, Belize, Nicaragua, Costa Rica and El Salvador; B. kuhniana (Clessin, 1883) in Panama; B. obstructa (Morelet,1849) in Guatemala, Belize and El Salvador; B. straminea (Dunker, 1848) in Costa Rica; B. subprona (Martens, 1899) in Guatemala; D. anatinum (Orbigny,1835) in Belize, Guatemala, Nicaragua and Costa Rica; D. depressissimum (Moricand,1839) in Nicaragua, Costa Rica and Panama; D. lucidum (Pfeiffer, 1839) in Guatemala, Belize and Nicaragua; D. surinamense (Clessin, 1884) in Costa Rica and Panama; and Gyraulus percarinatus sp. n. in Panama. The occurrence of B. kuhniana and D. surinamense is first recorded in Central America, and Gyraulus percarinatus is the first representative of the genus provenly occurring in the American continent south of the United States. The following synonymy is proposed: Planorbis declivis Tate, 1870 = Biomphalaria helophila (Orbigny, 1835); Planorbis isthmicus Pilsbry, 1920 = Biomphalaria kuhniana (Clessin, 1883); Planorbis cannarum Morelet, 1849 and Segmentina donbilli Tristram, 1861 = Biomphalaria obstructa (Morelet, 1849); and Planorbis yzabalensis Crosse & Fischer, 1879 = Drepanotrema anatinum (Orbigny, 1835), confirming Aguayo (1933).

Forearc Sliver Translation, a Lack of Arc-Normal Strain Accumulation, and Interplate Thrust Earthquakes: GPS Geodesy in Western Nicaragua

We have been investigating the kinematics of the Nicaraguan forearc using campaign GPS measurements of our geodetic network made over the last seven years (Turner et al., 2007). We currently have interseismic velocities for 18 campaign sites and have installed 10 additional sites in the backarc to investigate the nature of the transition from forearc sliver motion to stable Caribbean Plate motion. Our work focusing on the later issue is presented elsewhere at this meeting (Styron et al., 2007). Corrections for modeled coseismic offsets from the Jan. 13, 2001 Mw7.7 earthquake off the coast of El Salvador have been applied to our campaign site velocities. Some of our time-series are also strongly affected by coseismic and postseismic effects of the Oct. 9, 2004 Mw6.9 earthquake off of the coast of Nicaragua. The geodetic effects of this event are being removed from the affected time-series for interseismic velocity analysis. We have also derived interseismic velocities for five continuous GPS sites in the region. Our GPS results confirm previous predictions of northwest transport of a forearc sliver with an average Northwest velocity of ~15 mm yr-1, but show little evidence for an arc- normal component of strain accumulation associated with locking on the subduction interface. However, the amount of seismicity along this section of the Middle America Trench, including several recent large events such as the 1992 Mw7.6 and 2004 Mw6.9 earthquakes, indicates some amount of locking is present. Several possibilities may account for the apparent contradiction between the GPS results and observed seismicity. The locked zone may be too shallow and too far offshore for the arc-normal component to show up in our network, or the arc-normal signal may be masked by post-seismic effects from the 1992 offshore earthquake. If coupling between the downgoing slab and the overriding plate is weak or limited to a small seismogenic zone, then arc-parallel motion of the forearc sliver may

Water saturation of hydrothermal smectite-rich clay might have promoted slope instability prior to the 1998 debris avalanche at Casita volcano, Nicaragua

NASA Astrophysics Data System (ADS)

Delmelle, P.; Opfergelt, S.; Boivin, P.; Delvaux, B.

2006-12-01

In October 1998, a relatively small collapse (1 600 000 cubic meters) of a pre-existing scarp occurred on the southern flank of the dormant Casita volcano, Nicaragua. It resulted in a debris avalanche, which quickly transformed into a disastrous debris flow that destroyed two towns and killed more than 2500 people. The failure was shown to be triggered by an excess pore water pressure within highly fractured rocks, following prolonged seasonal rains and precipitations from Hurricane Mitch. This pressure was linked to the water saturation of a hydrothermally-altered clay bedrock impeding in-depth infiltration. Yet, the nature and amounts of the clay material involved in the slope failure were still unknown. Here we report on physical, chemical and mineralogical investigations aimed at quantifying the clay content, and identifying the layer silicates of the hydrothermally-altered clays uncovered by the 1998 debris avalanche. The fine clay material was exceptionally rich in smectite (up to 50 wt. percent), which swells upon wetting and shrinks during dry conditions (Opfergelt et al., 2006, Geophys. Res. Lett., 33 (15), L15305). The smectite belonged to the beidellite-montmorillonite series. The pervasive presence of water-saturated smectitic clay strongly reduced the permeability in depth, and also altered the rheological and mechanical properties of both the pre-failure rock mass and flow materials. The shrink-swell behavior progressively decreased the rock's shear strength, and gradually destabilized the overlying rock mass in the decades and centuries before the landslide, thereby contributing to slope instability. Prolonged intense rainfall led to the formation of incipient weak failure surfaces in the superficial rock mass. As provoked by water saturation, this process was likely favored by the rapid change of the mechanical properties of smectite-rich clays deposited in fracture, joint and gouge interfaces. We suggest that hazard assessments associated with

Diversified Native Species Restoration for Recovery of Multiple Ecosystem Services in a Highly Disturbed Tropical Dry Forest Landscape of Southwestern Nicaragua

Williams-Guillen, K.; Otterstrom, S.; Perla, C.

2015-12-01

Tropical dry forests have been reduced to a fraction of their original extent in the Neotropics due to conversion to agriculture and cattle pasture. While TDF can recover via natural regeneration, resulting forests are dominated by wind-dispersed pioneer species of limited value for frugivorous wildlife. Additionally, passive restoration can be perceived as "abandonment" resulting in neighbors casually invading property to rear livestock and extract timber. In 2007, the NGO Paso Pacífico initiated restoration in a highly degraded tropical dry forest landscape of southwestern Nicaragua; funded by an ex-ante carbon purchase, the project was designed to integrate multiple native tree species known to provide resources used by local wildlife. We restored roughly 400 hectares spanning a rainfall gradient from dry to transitional moist forest, using reforestation (planting 70 species of tree seedlings in degraded pastures on a 4x4 m grid, leaving occurring saplings) and assisted regeneration (clearing vines and competing vegetation from saplings in natural regeneration and strategically managing canopy cover). In just over seven years, mean carbon increased nearly threefold, from to 21.5±5.0 to 57.9±9.6 SE tonnes/ha. Current carbon stocks match those of 20-year-old forests in the area, accumulated in less than a decade. Stem density per 15-m radius plot decreased from 16.3±2.3 to 12.5±0.9 SE, while species richness increased from 3.9±0.4 to 18.4±1.4 SE. Alpha richness of woody stems across plots increased from 36 to 94 species, and over 20 tree species established as a result of natural dispersal and recruitment. We have observed sensitive species such as spider monkeys and parrots foraging in restoration areas. Managed reforestation is a highly effective method for rapidly restoring the functionality of multiple ecosystem services in degraded TDF, particularly when social and political realities force restoration to coexist with human productive activities

Objectives To estimate the prevalence and incidence of upper extremity musculoskeletal pain (UEMP) and related disability among office workers in Costa Rica, Nicaragua and Spain. Methods Data from the multinational CUPID study on 947 (93%) participants at baseline with 90% follow-up after 12 months. logistic regression was used to estimate the associations (odds ratios [ORs] and corresponding 95% confidence intervals [95%CIs]) between country and six outcomes: baseline prevalence of (1) UEMP in past 12 months, (2) UEMP in past month, and (3) disabling UEMP in past month; (4) incidence of new UEMP at follow-up; (5) incidence of new disabling UEMP at follow-up; and (6) persistence of UEMP at follow-up, after adjustment for sociodemographic, job-related and health-related covariates. Results Baseline prevalence of UEMP in the past month was higher in Costa Rica (53.6%) (OR=1.89; 95% CI: 1.36-2.62), and Nicaragua (51.9%) (OR=1.74; 95% CI: 1.28-2.35) than in Spain (38.4%). Compared to Spain (33.2%), the incidence of new UEMP was 50.4% in Costa Rica (OR=2.04; 95% CI: 1.34-3.12), and 60.2% in Nicaragua (OR=3.04; 95% CI: 2.06-4.50). The incidence of disabling UEMP was higher in Nicaragua (OR=2.57; 95% CI: 1.50-4.41) and Costa Rica (OR=2.16; 95% CI: 1.22-3.84) when compared to Spain. Conclusion Prevalence of UEMP was approximately 2-fold higher and its incidence 2- to 3-fold higher in Costa Rica and Nicaragua as compared with Spain. Between-country differences were only partially explained by the covariates analyzed. Research is needed to explore other aspects of work and cultural attributes that might explain the residual differences in UEMP. PMID:26972870

The A.D. 1835 eruption of Volcán Cosigüina, Nicaragua: A guide for assessing local volcanic hazards

2006-01-01

The January 1835 eruption of Volcán Cosigüina in northwestern Nicaragua was one of the largest and most explosive in Central America since Spanish colonization. We report on the results of reconnaissance stratigraphic studies and laboratory work aimed at better defining the distribution and character of deposits emplaced by the eruption as a means of developing a preliminary hazards assessment for future eruptions. On the lower flanks of the volcano, a basal tephra-fall deposit comprises either ash and fine lithic lapilli or, locally, dacitic pumice. An overlying tephra-fall deposit forms an extensive blanket of brown to gray andesitic scoria that is 35–60 cm thick at 5–10 km from the summit-caldera rim, except southwest of the volcano, where it is considerably thinner. The scoria fall produced the most voluminous deposit of the eruption and underlies pyroclastic-surge and -flow deposits that chiefly comprise gray andesitic scoria. In northern and southeastern sectors of the volcano, these flowage deposits form broad fans and valley fills that locally reach the Gulf of Fonseca. An arcuate ridge 2 km west of the caldera rim and a low ridge east of the caldera deflected pyroclastic flows northward and southeastward. Pyroclastic flows did not reach the lower west and southwest flanks, which instead received thick, fine-grained, accretionary-lapilli–rich ashfall deposits that probably derived chiefly from ash clouds elutriated from pyroclastic flows. We estimate the total bulk volume of erupted deposits to be ∼6 km3. Following the eruption, lahars inundated large portions of the lower flanks, and erosion of deposits and creation of new channels triggered rapid alluviation. Pre-1835 eruptions are poorly dated; however, scoria-fall, pyroclastic-flow, and lahar deposits record a penultimate eruption of smaller magnitude than that of 1835. It occurred a few centuries earlier—perhaps in the fifteenth century. An undated sequence of thick tephra-fall deposits on

Sulfur and halogen gases at Masaya Caldera Complex, Nicaragua: Total flux and variations with time

Stoiber, Richard E.; Williams, Stanley N.; Huebert, Barry J.

Santiago Crater, of Masaya Caldera Complex near Managua, Nicaragua, entered a phase of intense magmatic degassing in late 1979. The flux of SO2 increased rapidly from a previous average of 380 t d-1 to approximately 1200 t d-1 in February 1980. We report on results of a study of the gas flux and geochemistry conducted as part of a broader interdisciplinary study of the volcano and its impact on the adjacent environment. Masaya is an unusual volcano because of its low shield like form, consistent tholeiitic basaltic composition, frequent activity, and especially because of the approximately 25 year cycle of major non-eruptive degassing crises. We have used a combination of techniques involving remote sensing (using a correlation spectrometer (COSPEC)) of the flux of SO2 and direct filter sampling of the ratios of the sulfur and halogen gases and aerosols to quantify the flux of all of these species. The three-stage filters successively trap aerosols, halogen acid gases, and sulfur dioxide and are analyzed by ion chromatography. We have used the ratios of various species, with the COSPEC measurements of the flux of SO2, to calculate that the average flux of SO2 is 1275 t d-1, HCl is 830 t d-1, HF is about 16 t d-1, and HBr is at most 1 t d-1. H2S and SO4 = are only minor sulfur species. The flux of SO2 and HCl represents the largest reported noneruptive sustained volcanic release of these species in the world. Masaya contributed 7% of the total SO2 estimated to have been released by volcanoes worldwide in 1981. The flux of SO2 has declined by about 9% each year since 1979 and can be modeled as a first-order kinetic rate law with a decay constant of approximately 0.04 yr-1. Approximately 2.2 × 106 tons of SO2 has been released between September 1979 and September 1985. The ratio S/Cl has declined more rapidly than the flux of SO2, reflecting the greater solubility of HCl than SO2 in the magma. The SO2 flux at Santiago varies more widely within a single day than

Phylogenetics of Ogyges Kaup and the biogeography of Nuclear Central America (Coleoptera, Passalidae)

Abstract A phylogenetic morphological analysis of the genus Ogyges Kaup, distributed in Nuclear Central America, from Chiapas, Mexico, to northwestern Nicaragua was undertaken. Five species of Proculejus Kaup, distributed north of the Isthmus of Tehuantepec in Mexico, were selected as outgroup. Ogyges was recovered as monophyletic with three species groups: championi, laevissimus, and crassulus. Each species group shows a distinct, generally allopatric distribution. The O. championi species group, with ten species, is distributed in the Maya block, more specifically in the mountainous system north of the Motozintla-Comaltitlán fault in Chiapas, and north of the dry valleys of the Cuilco and Motagua rivers in Guatemala. The two remaining species groups are distributed in the Chortis block. The O. laevissimus species group, including seven species, ranges mostly along the Pacific Volcanic Chain from Guatemala to El Salvador, and from southeastern Honduras to the northwestern area of Nicaragua. The O. crassulus species group, with ten species, is distributed from northeastern Guatemala (Merendón) to northern Honduras. The Isthmus of Tehuantepec in Mexico, the Motagua-Cuilco and Motozintla-Comaltitlán sutures zones in Chiapas and Guatemala, the lowland valleys of Colón and Comalí rivers between Nicaragua and Honduras (or, perhaps, the northern suture of the Siuna Terrane in Nicaragua), the Guayape fault system in Honduras, and the intricate dry valleys of Ulúa-Chamelecón-Olancho in Honduras, are hypothesized to have acted as barriers that affected the geographical distribution of Ogyges, as well as probably other montane organisms.

Studies in different countries have identified irregular water supply as a risk factor for dengue virus transmission. In 2013, Camino Verde, a cluster-randomised controlled trial in Managua, Nicaragua, and Mexico's Guerrero State, demonstrated impact of evidence-based community mobilisation on recent dengue infection and entomological indexes of infestation by Aedes aegypti mosquitoes. This secondary analysis of data from the trial impact survey asks: (1) what is the importance of regular water supply in neighbourhoods with and without the trial intervention and (2) can community interventions like Camino Verde reasonably exclude households with adequate water supply? Entomological data collected in the dry season of 2013 in intervention and control communities allow contrasts between households with regular and irregular water supplies. Indicators of entomological risk included the House Index and pupa positive household index. Generalised linear mixed models with cluster as a random effect compared households with and without regular water, and households in intervention and control communities. For the House Index, regular water supply was associated with a protection in both intervention households (OR 0.7, 95%CI 0.6-0.9) and control households (OR 0.6, 95%CI 0.5-0.8). For the pupa positive household index, we found a similar protection from regular water supply in intervention households (OR 0.6, 95%CI 0.4-0.8) and control households (OR 0.7, 95%CI 0.5-0.9). The Camino Verde intervention had a similar impact on House Index in households with regular water supply (OR 0.7, 95%CI 0.5-1.0) and irregular water supply (OR 0.6, 95%CI 0.4-0.8); for the pupa positive household index, the effect of the intervention was very similar in households with regular (OR0.5, 95%CI 0.3-0.8) and irregular (OR 0.5, 95%CI 0.3-0.9) water supply. While Aedes aegypti control efforts based on informed community mobilisation had a strong impact on households without a regular water

Socio-economic resources may be associated with infant feeding in complex patterns in societies undergoing a nutrition transition. This study evaluates associations of housing quality, food security and maternal education to the World Health Organization (WHO) feeding recommendations and to consumption of highly processed snacks (HP snacks) and sugar-sweetened beverages (SSBs) in rural Nicaragua. Data were collected from May to November 2009, with mothers of 0- to 35-month-olds being asked about young child feeding using a food frequency questionnaire. A validated questionnaire was used to assess household food insecurity and data were collected on maternal education and housing quality. Pearson's chi-squared test was used to compare proportions and determine associations between the resources and young child feeding. The three socio-economic resources and other confounders were introduced to multivariate logistic regression analyses to assess the independent contribution of the resources to the feeding practices and consumption of HP snacks and SSBs. Mothers with the lowest education level were more likely to be exclusively breastfeeding (EBF) their infants (OR not EBF: 0.19; 95% CI: 0.07, 0.51), whilst mothers of 6- to 35-month-olds in the lowest education category had more inadequate dietary diversity (DD) (OR for not meet DD: 2.04; 95% CI: 1.36, 3.08), were less likely to consume HP snacks (OR for HP snacks: 0.47; 95% CI: 0.32, 0.68) and SSBs (OR for SSBs: 0.68; 95% CI: 0.46, 0.98), compared to mothers with the highest level of education. Similarly, children residing in households with the highest food insecurity were also more prone to have inadequate dietary diversity (OR for not meet DD: 1.47; 95% CI: 1.05, 2.05). The odds for double burden of suboptimal feeding (concurrent inadequate diet and consumption of HP snacks/SSBs) were significantly lower in children of least educated mothers (OR: 0.64; 95% CI: 0.44, 0.92).

The astonishing range of plants and animals of Central America's 7 countries (Guatemala, Belize, Honduras, El Salvador, Nicaragua, Costa Rica and Panama) is disappearing, as 60% of its forests have been cut for lumber and firewood as well as for cotton, cattle, or subsistence crops. Up to 5 million Mayans lived sustainably for thousands of years in an area now being destroyed by a few hundred thousand inhabitants. The Spanish colonization that started 500 years ago was concentrated in Panama, Nicaragua, and Guatemala. The majority of the English-speaking country of Belize are descended from the black slave population whose culture spread down the coast to Central America. Panama's service economy is based on the Panama Canal and trade and finance. Costa Rica benefits from a tourist industry based on its natural beauty, however, it also has the highest rate of deforestation and its fast population growth could jeopardize earlier social and economic progress. In El Salvador and Guatemala long periods of civil conflict have taken their toll on the economy and the environment. El Salvador has a mountainous territory and limited natural resources and industrialization, while the best land is in the hands of a few families. Honduras and Nicaragua retain the highest proportion of forest cover of the countries in the region, despite Nicaragua's years of tyranny, then revolution and the Contra war, and Honduras's own turmoils. Belize has achieved some stability, and is now strengthening its Central American links. Its coral reefs and coastal areas offer potential for sustainable development through fishing and tourism. Central American countries face the challenges of their fragile environments and major social problems.

Outpatient laparoscopy procedures have made sterilization possible for millions of women in developing countries. This report describes the experience of a team of doctors, nurses, and support staff that performed 107 laparoscopic tubal sterilizations during on eight-day sojourn in a remote north-central area of Nicaragua. Minimal analgesia (oral ibuprofen) and anesthesia (1% lidocaine) were used since most of the patients walked to and from the hospital-some up to 15 miles. Because the Nicaraguan government's support for birth-control programs is unreliable and because illegal abortion is the leading cause of maternal mortality in Nicaragua, this safe, minimally invasive surgical method is the favored means of birth control.

Timely and accurate measurement of population protection against measles is critical for decision-making and prevention of outbreaks. However, little is known about how survey-based estimates of immunization (crude coverage) compare to the seroprevalence of antibodies (effective coverage), particularly in low-resource settings. In poor areas of Mexico and Nicaragua, we used household surveys to gather information on measles immunization from child health cards and caregiver recall. We also collected dried blood spots (DBS) from children aged 12 to 23 months to compare crude and effective coverage of measles immunization. We used survey-weighted logistic regression to identify individual, maternal, household, community, and health facility characteristics that predict gaps between crude coverage and effective coverage. We found that crude coverage was significantly higher than effective coverage (83% versus 68% in Mexico; 85% versus 50% in Nicaragua). A large proportion of children (19% in Mexico; 43% in Nicaragua) had health card documentation of measles immunization but lacked antibodies. These discrepancies varied from 0% to 100% across municipalities in each country. In multivariate analyses, card-positive children in Mexico were more likely to lack antibodies if they resided in urban areas or the jurisdiction of De Los Llanos. In contrast, card-positive children in Nicaragua were more likely to lack antibodies if they resided in rural areas or the North Atlantic region, had low weight-for-age, or attended health facilities with a greater number of refrigerators. Findings highlight that reliance on child health cards to measure population protection against measles is unwise. We call for the evaluation of immunization programs using serological methods, especially in poor areas where the cold chain is likely to be compromised. Identification of within-country variation in effective coverage of measles immunization will allow researchers and public health

Are there trends towards drier hydrological conditions in Central America?

2013-12-01

A summary of hydrological projections at the end of the century from 30 General Circulation Models (GCMs) is presented; and several hydrometeorological parameters are analyzed to validate if there are hydroclimatological trends during the observational period (1982-2005) consistent with the GCMs results. At the end of the century the median of 30 GCM simulations projects a drier future for Tegucigalpa and San Jose, with a marked increment in evapotranspiration in the first half of the rainy season along with reductions of soil moisture. With respect to the observations (1982-2005): 1) the Normalized Difference Vegetation Index showed negative trends in the North Pacific coast of Costa Rica, the border of Honduras and Nicaragua, and especially in southern Mexico (except the Yucatan Peninsula). Positive trends were found in the several parts of Central America, 2) the Palmer Drought Severity Index showed strong and consistent trends from Nicaragua to the North of Central America and southern Mexico (not including Yucatan), consistent with the direction of GCM projections; 3) negative precipitation trends in satellite data were found in Nicaragua, with strong trends in its Caribbean coast; 4) NCEP/NCAR Reanalysis precipitation showed strong negative trends in northern Central America, the Central Valley, the Dry Pacific of Costa Rica and the South-Pacific coast of Nicaragua, all consistent with the direction of GCM projections; and 5) station data showed no significant trends however, and 6) Reanalysis' temperature showed positive trends in southern Mexico (not including Yucatan) and negative trends in El Salvador. It can be concluded that several trends in drought indexes and precipitation are consistent with the future projected by the GCMs; that is, with some exceptions some of the trends were validated towards a drier future for the region, especially in the northern part.

Curie point depth in the SW Caribbean using the radially averaged spectra of magnetic anomalies

Salazar, Juan M.; Vargas, Carlos A.; Leon, Hermann

2017-01-01

We have estimated the Curie Point Depth (CPD) using the average radial power spectrum in a tectonically complex area located in the SW Caribbean basin. Data analyzed came from the World Digital Magnetic Anomaly Map, and three methods have been used to compare results and evaluate uncertainties: Centroid, Spectral Peak, and Forward Modeling. Results show a match along the three methods, suggesting that the CPD values in the area ranging between 6 km and 50 km. The results share the following characteristics: A) High values (> 30 km) are in continental regions; B) There is a trend of maximum CPD values along the SW-NE direction, starting from the Central Cordillera in Colombia to the Maracaibo Lake in Venezuela; C) There is a maximum CPD at the Sierra Nevada de Santa Marta (Colombia) as well as between Costa Rica - Nicaragua and Nicaragua - Honduras borders. The lowest CPD values (< 20 km) are associated with the coastal regions and offshore. We also tested results by estimating the geothermal gradient and comparing measured observations of the study area. Our results suggest at least five thermal terrains in the SW Caribbean Basin: A) The area that is comprising the Venezuela Basin, the Beata Ridge and the Colombia Basin up to longitude parallel to the Providencia Throat. B) The area that includes zones to the north of the Cocos Ridge and Panam Basin up to the trench. C) The orogenic region of the northern Andes and including areas of the Santa Marta Massif. D) The continental sector that encompasses Nicaragua, northern Costa Rica and eastern of Honduras. E) Corresponds to areas of the northern Venezuela and Colombia, NW of Colombia, the Panamanian territory and the transition zones between the Upper and Lower Nicaragua Rise.

Intra-Arc extension in Central America: Links between plate motions, tectonics, volcanism, and geochemistry

NASA Astrophysics Data System (ADS)

Phipps Morgan, Jason; Ranero, Cesar; Vannucchi, Paola

2010-05-01

This study revisits the kinematics and tectonics of Central America subduction, synthesizing observations of marine bathymetry, high-resolution land topography, current plate motions, and the recent seismotectonic and magmatic history in this region. The inferred tectonic history implies that the Guatemala-El Salvador and Nicaraguan segments of this volcanic arc have been a region of significant arc tectonic extension; extension arising from the interplay between subduction roll-back of the Cocos Plate and the ~10-15 mm/yr slower westward drift of the Caribbean plate relative to the North American Plate. The ages of belts of magmatic rocks paralleling both sides of the current Nicaraguan arc are consistent with long-term arc-normal extension in Nicaragua at the rate of ~5-10 mm/yr, in agreement with rates predicted by plate kinematics. Significant arc-normal extension can ‘hide' a very large intrusive arc-magma flux; we suggest that Nicaragua is, in fact, the most magmatically robust section of the Central American arc, and that the volume of intrusive volcanism here has been previously greatly underestimated. Yet, this flux is hidden by the persistent extension and sediment infill of the rifting basin in which the current arc sits. Observed geochemical differences between the Nicaraguan arc and its neighbors which suggest that Nicaragua has a higher rate of arc-magmatism are consistent with this interpretation. Smaller-amplitude, but similar systematic geochemical correlations between arc-chemistry and arc-extension in Guatemala show the same pattern as the even larger variations between the Nicaragua arc and its neighbors. We are also exploring the potential implications of intra-arc extension for deformation processes along the subducting plate boundary and within the forearc ‘microplate'.

Walking through volcanic mud: the 2,100 year-old Acahualinca footprints (Nicaragua) II: the Acahualinca people, environmental conditions and motivation

NASA Astrophysics Data System (ADS)

Schmincke, Hans-Ulrich; Rausch, Juanita; Kutterolf, Steffen; Freundt, Armin

2010-10-01

We analyzed bare human footprints in Holocene tuff preserved in two pits in the Acahualinca barrio in the northern outskirts of Managua (Nicaragua). Lithology, volcanology, and age of the deposits are discussed in a companion paper (Schmincke et al. Bull Volcanol doi: 10.1007/s00445-008-0235-9 , 2008). The footprint layer occurs within a series of rapidly accumulated basaltic-andesitic tephra that is regionally correlated to the Masaya Triple Layer Tephra. The people were probably trying to escape from a powerful volcanic eruption at Masaya Caldera 20 km farther south that occurred at 2.1 ka BP. We subdivided the swath of footprints, up to 5.6 m wide, in the northern pit (Pit I) into (1) a central group of footprints made by about six individuals, the total number being difficult to determine because people walked in each other’s footsteps one behind the other and (2) two marginal groups on either side of the central group with more widely spaced tracks. The western band comprises tracks of three adjacent individuals and an isolated single footprint farther out. The eastern marginal area comprises an inner band of deep footprints made by three individuals and, farther out, three clearly separated individuals. We estimate the total number of people as 15-16. In the southern narrow and smaller pit (Pit II), we recognize tracks of ca. 12 individuals, no doubt made by the same group. The group represented in both pits probably comprised male and female adults, teenagers and children based on differences in length of footprints and of strides and depth of footprints made in the soft wet ash. The smallest footprints (probably made by children) occur in the central group, where protection was most effective. The footprint layer is composed of a lower 5-15-cm thick, coarse-grained vesicle tuff capped by a medium to fine-grained tuff up to 3 cm thick. The

Gender inequity negatively affects health in Central America. In 2011, we conducted 60 semistructured interviews and 12 photovoice focus groups with young coupled men and women in León, Nicaragua, to explore the ways in which social norms around marriage and gender affect sexual health and gender-based violence. Participants' depictions of their experiences revealed gendered norms around infidelity that provided a narrative to justify male expressions of jealousy, which included limiting partner autonomy, sexual coercion, and physical violence against women, and resulted in increased women's risk of sexually transmitted infections, including HIV. By understanding and taking account of these different narratives and normalized beliefs in developing health- and gender-based violence interventions, such programs might be more effective in promoting gender-equitable attitudes and behaviors among young men and women in Nicaragua.

Rapid Determination of Appropriate Source Models for Tsunami Early Warning using a Depth Dependent Rigidity Curve: Method and Numerical Tests

NASA Astrophysics Data System (ADS)

Tanioka, Y.; Miranda, G. J. A.; Gusman, A. R.

2017-12-01

Recently, tsunami early warning technique has been improved using tsunami waveforms observed at the ocean bottom pressure gauges such as NOAA DART system or DONET and S-NET systems in Japan. However, for tsunami early warning of near field tsunamis, it is essential to determine appropriate source models using seismological analysis before large tsunamis hit the coast, especially for tsunami earthquakes which generated significantly large tsunamis. In this paper, we develop a technique to determine appropriate source models from which appropriate tsunami inundation along the coast can be numerically computed The technique is tested for four large earthquakes, the 1992 Nicaragua tsunami earthquake (Mw7.7), the 2001 El Salvador earthquake (Mw7.7), the 2004 El Astillero earthquake (Mw7.0), and the 2012 El Salvador-Nicaragua earthquake (Mw7.3), which occurred off Central America. In this study, fault parameters were estimated from the W-phase inversion, then the fault length and width were determined from scaling relationships. At first, the slip amount was calculated from the seismic moment with a constant rigidity of 3.5 x 10**10N/m2. The tsunami numerical simulation was carried out and compared with the observed tsunami. For the 1992 Nicaragua tsunami earthquake, the computed tsunami was much smaller than the observed one. For the 2004 El Astillero earthquake, the computed tsunami was overestimated. In order to solve this problem, we constructed a depth dependent rigidity curve, similar to suggested by Bilek and Lay (1999). The curve with a central depth estimated by the W-phase inversion was used to calculate the slip amount of the fault model. Using those new slip amounts, tsunami numerical simulation was carried out again. Then, the observed tsunami heights, run-up heights, and inundation areas for the 1992 Nicaragua tsunami earthquake were well explained by the computed one. The other tsunamis from the other three earthquakes were also reasonably well explained

Tectonic Structure of the Middle America Pacific Margin and Incoming Cocos Plate From Costa Rica to Guatemala

NASA Astrophysics Data System (ADS)

Ranero, C. R.; Weinrebe, W.; Grevemeyer, I.; Phipps Morgan, J.; Vannucchi, P.; von Huene, R.

2003-12-01

A new multibeam bathymetry and magnetic survey with R/V SONNE in summer 2003 has mapped the continental margin and incoming plate of NW Nicaragua, El Salvador and Guatemala, extending existing coverage from offshore Costa Rica and part of Nicaragua to a full coverage map of about 1200 km long by 100 km wide area along the plate boundary. The incoming plate along Nicaragua, El Salvador and Guatemala is of similar age and was formed at superfast spreading rates; however, its morphology changes drastically along strike. The seafloor-spreading inherited morphology is very smooth along Nicaragua, but with ridges up to 800 m high in Guatemala, with a transition across El Salvador. The development and dimensions of the dominant inherited fabric seems to be related to discontinuities at the paleospreading center. A series of troughs oblique to the main fabric may indicate the location of pseudofaults and correspond to areas where the seafloor fabric is most prominent. Bending of the oceanic plate into the trench reactivates the inherited fabric forming a well pervasive faulting system along the oceanic trench slope. The continental slope displays three morphotectonic units that roughly correspond to the upper, middle and lower slope, although the across slope width of each unit is fairly variable. Small canyons and gullies that form at the sudden dip change across the shelf break carve the upper slope. The canyons coalesce and become shallower as the dip decreases downslope. Locally some large canyons continue into the slope toe. The middle slope is a rough terrain variable in width and dip sculptured by pervasive normal faulting and locally by mass wasting processes. The lower slope is formed by en echelon terraces striking similar to the rough terrain of the incoming plate and mimicking the half graben morphology of the underthusting plate. The three morphotectonic slope domains represent differences in tectonic activity, with more stable upper slope, a middle slope

Adolescent sexual behavior and reproductive outcomes in Central America: trends over the past two decades.

PubMed

Samandari, Ghazaleh; Speizer, Ilene S

2010-03-01

Compared with the Latin American average, adolescent fertility is high in El Salvador, Guatemala, Honduras and Nicaragua, countries that also have high poverty levels and poor access to reproductive health care. For each country, data were drawn from four national health surveys conducted between 1987 and 2007, and analysis focused on trends in sexual and reproductive behavior among adolescent females aged 15-19. Event history analysis examined transitions to first sexual intercourse, first union and first live birth across survey years; Cox hazard and logistic regression analyses assessed associations between selected demographic characteristics and these outcomes, as well as ever-use of a modern contraceptive method. The likelihood that adolescent females have initiated sexual intercourse has increased over time in El Salvador, Honduras and Nicaragua, and has remained stable in Guatemala. Meanwhile, the odds of having entered their first union have declined in Nicaragua and risen in El Salvador, but have not changed in Honduras or Guatemala. Notably, the likelihood that adolescents have ever used a modern contraceptive method has increased in all four countries over the survey years. Nicaraguan adolescents became significantly less likely to have had their first live birth over the study period. Finally, urban residence, education level and socioeconomic status were important predictors of adolescents' sexual and reproductive outcomes. Programmatic and policy initiatives should focus on improving adolescents' education and socio- economic prospects, and efforts are especially needed to help adolescents delay the age at which they become sexually active and enter their first union.

Magnitude scale for the Central American tsunamis

NASA Astrophysics Data System (ADS)

Hatori, Tokutaro

1995-09-01

Based on the tsunami data in the Central American region, the regional characteristic of tsunami magnitude scales is discussed in relation to earthquake magnitudes during the period from 1900 to 1993. Tsunami magnitudes on the Imamura-Iida scale of the 1985 Mexico and 1992 Nicaragua tsunamis are determined to be m=2.5, judging from the tsunami height-distance diagram. The magnitude values of the Central American tsunamis are relatively small compared to earthquakes with similar size in other regions. However, there are a few large tsunamis generated by low-frequency earthquakes such as the 1992 Nicaragua earthquake. Inundation heights of these unusual tsunamis are about 10 times higher than those of normal tsunamis for the same earthquake magnitude ( M s =6.9 7.2). The Central American tsunamis having magnitude m>1 have been observed by the Japanese tide stations, but the effect of directivity toward Japan is very small compared to that of the South American tsunamis.

Addressing the needs of Nicaraguan older adults living on the edge: A university-community partnership in international service-learning.

Nicaragua is a very low-income country entering a period of rapid aging with limited geriatric training for health care professionals. To help build capacity and to enhance student learning, a short-term international service-learning program was implemented in 2004 in partnership with the Jessie F. Richardson Foundation and Nicaraguan community stakeholders. Graduate and undergraduate students at Portland State University complete coursework for one term in the United States then travel to Nicaragua for about two weeks to participate in educational, research, and service activities, primarily in group homes for older Nicaraguans. Students learn about global aging, gerontology, community development, service learning, and Nicaraguan history and culture, then apply their gerontology-related knowledge by training direct care staff, older adults and their family members, and students. The authors describe the impetus for and evolution of the program, students' evaluation of the program, faculty observations on program benefits and challenges, lessons learned, and future plans.

Impact of a nutrition intervention program on the growth and nutritional status of Nicaraguan adolescent girls.

PubMed

Pawloski, Lisa Renee; Moore, Jean Burley

2007-06-01

This research examines the impact of a nutrition education intervention program on the nutritional status and knowledge of Nicaraguan adolescent girls. Anthropometric measurements, hemoglobin values, and data concerning nutritional knowledge were collected from adolescent girls living in Managua, Nicaragua. Using a pre-test/post-test design, data are compared prior to and after the nutrition intervention program. When using Mexican American reference data, statistically significant differences in height-for-age z-scores and weight-for-age z-scores were found when comparing the entire sample of baseline data with data collected after three years of the nutrition intervention program (p < 0.05). Significant improvement was also found concerning the indicators of nutritional knowledge (p < 0.05). However, hemoglobin data revealed a significant decrease which may be due to specific environmental factors and pubertal changes. This research has implications concerning the development of successful adolescent focused nutrition intervention programs in Nicaragua, and examines the possibility that catch-up growth occurs during adolescence.

Health and health services in Central America.

PubMed

Garfield, R M; Rodriguez, P F

1985-08-16

Despite rapid economic growth since World War II, health conditions improved only slowly in most of Central America. This is a result of poor medical, social, and economic infrastructure, income maldistribution, and the poor utilization of health investments. The economic crisis of the 1980s and civil strife have further endangered health in the region. Life expectancy has fallen among men in El Salvador and civil strife has become the most common cause of death in Guatemala, Nicaragua, and El Salvador. Large-scale US assistance has done little to improve conditions, and refugees continue to pour into North America. It is estimated that there are more than a million refugees within Central America, while a million have fled to the United States. Costa Rica and Nicaragua are partial exceptions to this dismal health picture. An effective approach to the many health problems in Central America will require joint planning and cooperation among all countries in the region.

Disaster mitigation and preparedness on the Nicaraguan post-Mitch agenda.

PubMed

Rocha, J L; Christoplos, I

2001-09-01

Nicaragua provides an example of how a major disaster, in this case Hurricane Mitch, can transform the national agenda for disaster mitigation and preparedness. Hurricane Mitch was a reminder of how extremely disaster prone Nicaragua is, and also how neoliberal reforms have weakened governmental response capacity. In the face of critiques of how governmental policies had affected preparedness and response, discussions of this transformation became a highly politicised process where the debate over alternative development models tended to overshadow the original calls to strengthen risk management. Progress can be seen in some areas, such as disaster mitigation through environmental management. This study of NGO roles, and their relations with other key actors, draws attention to the need to anchor improved risk management in local-level NGO-government collaboration. Structures are being put into place to achieve this aim, but dependence on donor financing raises questions regarding the longer-term sustainability of these efforts.

Learning from recovery after Hurricane Mitch.

Christoplos, Ian; Rodríguez, Tomás; Schipper, E Lisa F; Narvaez, Eddy Alberto; Bayres Mejia, Karla Maria; Buitrago, Rolando; Gómez, Ligia; Pérez, Francisco J

2010-04-01

This paper reviews how Nicaragua has recovered from Hurricane Mitch of October 1998. In particular, it examines how the assumptions and claims that were made during initial recovery planning have proven relevant in light of subsequent development. One must consider the response to Hurricane Mitch from the perspective of the broader trends that have driven recovery, including household, community and government initiatives and the wider economic context. Recovery efforts have not 'transformed' Nicaragua. In fact, market upheavals and livelihood changes in rural areas have had a more profound impact on poverty profiles than recovery programmes. Social protection programmes have been piloted, but patron-client ties and relations with aid providers are still more reliable sources of support in a time of crisis. Risk reduction has become more deeply integrated into the rural development discourse than was the case before the disaster, but risk reduction initiatives continue to place undue emphasis on hazard response rather than addressing vulnerability.

The Generation of Continents through Subduction Zone Processing of Large Igneous Provinces: A Case Study from the Central American Subduction Zone

NASA Astrophysics Data System (ADS)

Harmon, N.; Rychert, C.

2013-12-01

Billions of years ago primary mantle magmas evolved to form the continental crust, although no simple magmatic differentiation process explains the progression to average andesitic crustal compositions observed today. A multiple stage process is often invoked, involving subduction and or oceanic plumes, to explain the strong depletion observed in Archean xenoliths and as well as pervasive tonalite-trondhjemite-granodiorite and komatiite protoliths in the greenstone belts in the crust in the cratons. Studying modern day analogues of oceanic plateaus that are currently interacting with subductions zones can provide insights into continental crust formation. Here we use surface waves to image crustal isotropic and radially anisotropic shear velocity structure above the central American subduction system in Nicaragua and Costa Rica, which juxtaposes thickened ocean island plateau crust in Costa Rica with continental/normal oceanic crust in Nicaragua. We find low velocities beneath the active arc regions (3-6% slower than the surrounding region) and up to 6% radially anisotropic structures within the oceanic crust of the Caribbean Large Igneous Province beneath Costa Rica. The low velocities and radial anisotropy suggest the anomalies are due to pervasive deep crustal magma sills. The inferred sill structures correlate spatially with increased silicic outputs in northern Costa Rica, indicating that deep differentiation of primary magmas is more efficient beneath Costa Rica relative to Nicaragua. Subduction zone alteration of large igneous provinces promotes efficient, deep processing of primary basalts to continental crust. This scenario can explain the formation of continental lithosphere and crust, by both providing strongly depleted mantle lithosphere and a means for rapidly generating a silicic crustal composition.

Earth Observations taken by the Expedition 16 Crew

ISS016-E-010894 (17 Nov. 2007) --- Cosiguina Volcano, Nicaragua is featured in this image photographed by an Expedition 16 crewmember on the International Space Station. Three Central American countries (El Salvador, Honduras, and Nicaragua) include coastline along the Gulf of Fonseca that opens into the Pacific Ocean. The southern boundary of the Gulf is a peninsula formed by the Cosiguina volcano illustrated in this view. Cosiguina is a stratovolcano, typically tall cone-shaped structures formed by alternating layers of solidified lava and volcanic rocks (ash, pyroclastic flows, breccias) produced by explosive eruptions. The summit crater is filled with a lake (Laguna Cosiguina). The volcano last erupted in 1859, but its most famous activity occurred in 1835 when it produced the largest historical eruption in Nicaragua. Ash from the 1835 eruption has been found in Mexico, Costa Rica, and Jamaica. The volcano has been quiet since 1859, only an instant in terms of geological time. An earthquake swarm was measured near Cosiguina in 2002, indicating that tectonic forces are still active in the region although the volcano is somewhat isolated from the line of more recently active Central American volcanoes to the northwest and southeast. Intermittently observed gas bubbles in Laguna Cosiguina, and a hot spring along the eastern flank of the volcano are the only indicators of hydrothermal activity at the volcano. The fairly uniform vegetation cover (green) on the volcano's sides also attest to a general lack of gas emissions or "hot spots" on the 872 meter high cone, according to NASA scientists who study the photos downlinked from the orbital outpost.

Use of Remote Sensing/Geographical Information Systems (RS/GIS) to Identify the Distributional Limits of Soil-Transmitted Helminths (STHs) and Their Association to Prevalence of Intestinal Infection in School-Age Children in Four Rural Communities in Boaco, Nicaragua

NASA Technical Reports Server (NTRS)

Moreno, Max J.; Al-Hamdan, Mohammad Z.; Parajon, David G.; Rickman, Douglas L.; Luvall, Jeffrey; Parajon, Laura C.; Martinez, Roberto A.; Estes, Sue

2011-01-01

STHs can infect all members of a population but school-age children living in poverty are at greater risk. Infection can be controlled with drug treatment, health education and sanitation. Helminth control programs often lack resources and reliable information to identify areas of highest risk to guide interventions and to monitor progress. Objectives: To use RS/GIS to identify the environmental variables that correlate with the ecology of STHs and with the prevalence of STH infections. Methods: Geo-referenced in situ prevalence data will be overlaid over an ecological map derived from the RS environmental data using ESRI s ArcGIS 9.3. Prevalence data and RS environmental data matching at the same geographical location will be analyzed for correlation and those RS environmental variables that better correlate with prevalence data will be included in a multivariate regression model. Temperature, vegetation, and distance to bodies of water will be inferred using data from the Moderate-Resolution Imaging Spectroradiometer (MODIS) onboard the Terra and Aqua satellites, and Thematic Mapper (TM) and Enhance Thematic Mapper Plus (ETM+) satellite sensors onboard Landsat 5 and Landsat 7 respectively. Elevation will be estimated with data from The Shuttle Radar Topography Mission (SRTM). Prevalence and intensity of infections will be determined by parasitological survey (Kato Katz) of children enrolled in rural schools in Boaco, Nicaragua, in the communities of El Roblar, Cumaica Norte, Malacatoya 1, and Malacatoya 2). Expected Results: Associations between RS environmental data and prevalence in situ data will be determined and their applications to public health will be discussed. Discussion/Conclusions: The use of RS/GIS data to predict the prevalence of STH infections could be useful for helminth control programs, providing improved geographical guidance of interventions while increasing cost-effectiveness. Learning Objectives: (1) To identify the RS environmental

2015-12-01

Neotropical dry forests (TDF) have experienced an unprecedented deforestation that is leading to the loss of tropical biodiversity at a rapid pace, but information on deforestation dynamics in TDF is scarce. In this study, we present a sub-continental and national level assessment of TDF loss patterns in Mexico and Central America at high spatial and temporal resolution using remote sensing and GIS technologies. We used the Global Forest Change (GFC) dataset published by Hansen et al. (2013) which shows results from time-series analysis of Landsat images in characterizing global forest extent and change from 2000 through 2013. We analyzed forest loss within and around mapped TDF cover mapped by Portillo-Quintero et al. 2010. In order to minimize errors in source data, we overlaid a 25 x 25 km grid on top of the regional dataset and conducted a cell by cell and country by country inspection at multiple scales using high resolution ancillary data. We identified trends in the clustering of space-time TDF deforestation data using ArcGIS, categorizing trends in: new, consecutive, intensifying, persistent, diminishing, sporadic, oscillating and historical hotspots (high frequency of deforestation events) and cold spots (low frequency of deforestation). In general, the region is experiencing less frequent deforestation events with a higher number of intensifying and new cold spots across TDF landscapes. However, an important number of intensifying and persistent hotspots exist so no general trend in forest loss was detected for the period 2001-2013, except for El Salvador which shows a significant decreasing trend in forest loss. Mexico, Nicaragua, Honduras and Guatemala are the major sources of intensifying, persistent and new deforestation hot spots. These were identified in the southern pacific coast and the Yucatan Peninsula in Mexico, northwestern Guatemala, both western and eastern Honduras and around Lake Nicaragua in Nicaragua.

Dialysis enrollment patterns in Guatemala: evidence of the chronic kidney disease of non-traditional causes epidemic in Mesoamerica.

PubMed

Laux, Timothy S; Barnoya, Joaquin; Guerrero, Douglas R; Rothstein, Marcos

2015-04-14

In western Nicaragua and El Salvador, chronic kidney disease (CKD) is highly prevalent and generally affects young, male, agricultural (usually sugar cane) workers without the established CKD risk factors. It is yet unknown if the prevalence of this CKD of Non-Traditional causes (CKDnT) extends to the northernmost Central American country, Guatemala. Therefore, we sought to compare dialysis enrollment rates by region, municipality, sex, daily temperature, and agricultural production in Guatemala and assess if there is a similar CKDnT distribution pattern as in Nicaragua and El Salvador. The National Center for Chronic Kidney Disease Treatment (Unidad Nacional de Atención al Enfermo Renal Crónico) is the largest provider of dialysis in Guatemala. We used population, Human Development Index, literacy, and agricultural databases to assess the geographic, economic, and educational correlations with the National Center for Chronic Kidney Disease Treatment's hemodialysis and peritoneal dialysis enrollment database. Enrollment rates (per 100 000) inhabitants were compared by region and mapped for comparison to regional agricultural and daytime temperature data. The distribution of men and women enrolled in dialysis were compared by region using Fisher's exact tests. Spearman's rank correlation coefficients were calculated. Dialysis enrollment is higher in the Southwest compared to the rest of the country where enrollees are more likely (p < 0.01) to be male (57.8%) compared to the rest of the country (49.3%). Dialysis enrollment positively correlates with Human Development Index and literacy rates. These correlations are weaker in the agricultural regions (predominantly sugar cane) of Southwest Guatemala. In Guatemala, CKDnT incidence may have a similar geographic distribution as Nicaragua and El Salvador (higher in the high temperature and sugar cane growing regions). Therefore, it is likely that the CKNnT epidemic extends throughout the Mesoamerican region.

This case history discusses the exploration methods used at the Momotombo Geothermal Field in western Nicaragua, and evaluates their contributions to the development of the geothermal field models. Subsequent reservoir engineering has not been synthesized or evaluated. A geothermal exploration program was started in Nicaragua in 1966 to discover and delineate potential geothermal reservoirs in western Nicaragua. Exploration began at the Momotombo field in 1970 using geological, geochemical, and geophysical methods. A regional study of thermal manifestations was undertaken and the area on the southern flank of Volcan Momotombo was chosen for more detailed investigation. Subsequent exploration by various consultantsmore » produced a number of geotechnical reports on the geology, geophysics, and geochemistry of the field as well as describing production well drilling. Geological investigations at Momotombo included photogeology, field mapping, binocular microscope examination of cuttings, and drillhole correlations. Among the geophysical techniques used to investigate the field sub-structure were: Schlumberger and electromagnetic soundings, dipole mapping and audio-magnetotelluric surveys, gravity and magnetic measurements, frequency domain soundings, self-potential surveys, and subsurface temperature determinations. The geochemical program analyzed the thermal fluids of the surface and in the wells. This report presents the description and results of exploration methods used during the investigative stages of the Momotombo Geothermal Field. A conceptual model of the geothermal field was drawn from the information available at each exploration phase. The exploration methods have been evaluated with respect to their contributions to the understanding of the field and their utilization in planning further development. Our principal finding is that data developed at each stage were not sufficiently integrated to guide further work at the field, causing inefficient use

To develop and evaluate serological methods for chikungunya diagnosis and research in Nicaragua. Two IgM ELISA capture systems (MAC-ELISA) for diagnosis of acute chikungunya virus (CHIKV) infections, and two Inhibition ELISA Methods (IEM) to measure total antibodies against CHIKV were developed using monoclonal antibodies (mAbs) and hyperimmune serum at the National Virology Laboratory of Nicaragua in 2014-2015. The sensitivity, specificity, predictive values, and agreement of the MAC-ELISAs were obtained by comparing the results of 198 samples (116 positive; 82 negative) with the Centers for Disease Control and Prevention's IgM ELISA (Atlanta, Georgia, United States; CDC-MAC-ELISA). For clinical evaluation of the four serological techniques, 260 paired acute and convalescent phase serum samples of suspected chikungunya cases were used. All four assays were standardized by determining the optimal concentrations of the different reagents. Processing times were substantially reduced compared to the CDC-MAC-ELISA. For the MAC-ELISA systems, a sensitivity of 96.6% and 97.4%, and a specificity of 98.8% and 91.5% were obtained using mAb and hyperimmune serum, respectively, compared with the CDC method. Clinical evaluation of the four serological techniques versus the CDC real-time RT-PCR assay resulted in a sensitivity of 95.7% and a specificity of 88.8%-95.9%. Two MAC-ELISA and two IEM systems were standardized, demonstrating very good quality for chikungunya diagnosis and research demands. This will achieve more efficient epidemiological surveillance in Nicaragua, the first country in Central America to produce its own reagents for serological diagnosis of CHIKV. The methods evaluated here can be applied in other countries and will contribute to sustainable diagnostic systems to combat the disease.

Seismic evidence for hydration of the Central American slab: Guatemala through Costa Rica

NASA Astrophysics Data System (ADS)

Syracuse, E. M.; Thurber, C. H.

2011-12-01

The Central American subduction zone exhibits a wide variability in along-arc slab hydration as indicated by geochemical studies. These studies generally show maximum slab contributions to magma beneath Nicaragua and minimum contributions beneath Costa Rica, while intermediate slab fluid contributions are found beneath El Salvador and Guatemala. Geophysical studies suggest strong slab serpentinization and fluid release beneath Nicaragua, and little serpentinization beneath Costa Rica, but the remainder of the subduction zone is poorly characterized seismically. To obtain an integrated seismic model for the Central American subduction zone, we combine 250,000 local seismic arrivals and 1,000,000 differential arrivals for 6,500 shallow and intermediate-depth earthquakes from the International Seismic Centre, the Central American Seismic Center, and the temporary PASSCAL TUCAN array. Using this dataset, we invert for Vp, Vs, and hypocenters using a variable-mesh double-difference tomography algorithm. By observing low-Vp areas within the normally high-Vp slab, we identify portions of the slab that are likely to contain serpentinized mantle, and thus contribute to higher degrees of melting and higher volatile components observable in arc lavas.

Recent outbreaks of measles in the Americas have received news and popular attention, noting the importance of vaccination to population health. To estimate the potential increase in immunization coverage and reduction in days at risk if every opportunity to vaccinate a child was used, we analyzed vaccination histories of children 11-59 months of age from large household surveys in Mesoamerica. Our study included 22,234 children aged less than 59 months in El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Child vaccination cards were used to calculate coverage of measles, mumps, and rubella (MMR) and to compute the number of days lived at risk. A child had a missed opportunity for vaccination if their card indicated a visit for vaccinations at which the child was not caught up to schedule for MMR. A Cox proportional hazards model was used to compute the hazard ratio associated with the reduction in days at risk, accounting for missed opportunities. El Salvador had the highest proportion of children with a vaccine card (91.2%) while Nicaragua had the lowest (76.5%). Card MMR coverage ranged from 44.6% in Mexico to 79.6% in Honduras while potential coverage accounting for missed opportunities ranged from 70.8% in Nicaragua to 96.4% in El Salvador. Younger children were less likely to have a missed opportunity. In Panama, children from households with higher expenditure were more likely to have a missed opportunity for MMR vaccination compared to the poorest (OR 1.62, 95% CI: 1.06-2.47). In Nicaragua, compared to children of mothers with no education, children of mothers with primary education and secondary education were less likely to have a missed opportunity (OR 0.46, 95% CI: 0.24-0.88 and OR 0.25, 95% CI: 0.096-0.65, respectively). Mean days at risk for MMR ranged from 158 in Panama to 483 in Mexico while potential days at risk ranged from 92 in Panama to 239 in El Salvador. Our study found high levels of missed opportunities for immunizing

The purpose of this study was to examine the effect of a community-based nutrition education program on the nutritional knowledge, hemoglobin levels, and nutritional status of Nicaraguan adolescent girls and the nutritional knowledge of their mothers. Self-care deficit nursing theory was used in this study. This longitudinal study used a mixed quantitative/qualitative design to study the effect of the nutrition education program. The nonprobability sample consisted of 182 adolescent girls and 67 of their mothers. The setting for the study was a community (barrio) in Managua, Nicaragua. INTERVENTION/MEASUREMENT: A team of nurse and nutrition researchers created the nutrition education program designed to improve girls' and mother's nutrition-related self-care operations. Data collection was carried out for 4 years for girls and 2 years for mothers in Managua, Nicaragua, using questionnaires, a HemoCue, and anthropometric measures. The findings of this study were that girls' and mothers' nutritional knowledge scores significantly improved in most cases after participation in the nutrition intervention program. Girls' hemoglobin levels did not significantly improve and their nutritional status findings were mixed. Girls and mothers described what dietary changes girls made and why.

A rapid estimation of near field tsunami run-up

USGS Publications Warehouse

Riqueime, Sebastian; Fuentes, Mauricio; Hayes, Gavin; Campos, Jamie

2015-01-01

Many efforts have been made to quickly estimate the maximum run-up height of tsunamis associated with large earthquakes. This is a difficult task, because of the time it takes to construct a tsunami model using real time data from the source. It is possible to construct a database of potential seismic sources and their corresponding tsunami a priori.However, such models are generally based on uniform slip distributions and thus oversimplify the knowledge of the earthquake source. Here, we show how to predict tsunami run-up from any seismic source model using an analytic solution, that was specifically designed for subduction zones with a well defined geometry, i.e., Chile, Japan, Nicaragua, Alaska. The main idea of this work is to provide a tool for emergency response, trading off accuracy for speed. The solutions we present for large earthquakes appear promising. Here, run-up models are computed for: The 1992 Mw 7.7 Nicaragua Earthquake, the 2001 Mw 8.4 Perú Earthquake, the 2003Mw 8.3 Hokkaido Earthquake, the 2007 Mw 8.1 Perú Earthquake, the 2010 Mw 8.8 Maule Earthquake, the 2011 Mw 9.0 Tohoku Earthquake and the recent 2014 Mw 8.2 Iquique Earthquake. The maximum run-up estimations are consistent with measurements made inland after each event, with a peak of 9 m for Nicaragua, 8 m for Perú (2001), 32 m for Maule, 41 m for Tohoku, and 4.1 m for Iquique. Considering recent advances made in the analysis of real time GPS data and the ability to rapidly resolve the finiteness of a large earthquake close to existing GPS networks, it will be possible in the near future to perform these calculations within the first minutes after the occurrence of similar events. Thus, such calculations will provide faster run-up information than is available from existing uniform-slip seismic source databases or past events of pre-modeled seismic sources.

The 10 April 2014 Nicaraguan Crustal Earthquake: Evidence of Complex Deformation of the Central American Volcanic Arc

On 10 April 2014, an M w 6.1 earthquake struck central Nicaragua. The main event and the aftershocks were clearly recorded by the Nicaraguan national seismic network and other regional seismic stations. These crustal earthquakes were strongly felt in central Nicaragua but caused relatively little damage. This is in sharp contrast to the destructive effects of the 1972 earthquake in the capital city of Managua. The differences in damage stem from the fact that the 1972 earthquake occurred on a fault beneath the city; in contrast, the 2014 event lies offshore, under Lake Managua. The distribution of aftershocks of the 2014 event shows two clusters of seismic activity. In the northwestern part of Lake Managua, an alignment of aftershocks suggests a northwest to southeast striking fault, parallel to the volcanic arc. The source mechanism agrees with this right-lateral, strike-slip motion on a plane with the same orientation as the aftershock sequence. For an earthquake of this magnitude, seismic scaling relations between fault length and magnitude predict a sub-surface fault length of approximately 16 km. This length is in good agreement with the extent of the fault defined by the aftershock sequence. A second cluster of aftershocks beneath Apoyeque volcano occurred simultaneously, but spatially separated from the first. There is no clear alignment of the epicenters in this cluster. Nevertheless, the decay of the number of earthquakes beneath Apoyeque as a function of time shows the typical behavior of an aftershock sequence and not of a volcanic swarm. The northeast-southwest striking Tiscapa/Ciudad Jardín and Estadio faults that broke during the 1972 and 1931 Managua earthquakes are orthogonal to the fault where the 10 April earthquake occurred. These orthogonal faults in close geographic proximity show that Central Nicaragua is being deformed in a complex tectonic setting. The Nicaraguan forearc sliver, between the trench and the volcanic arc, moves to the

Finite-time singularity signature of hyperinflation

We present a novel analysis extending the recent work of Mizuno et al. (Physica A 308 (2002) 411) on the hyperinflations of Germany (1920/1/1-1923/11/1), Hungary (1945/4/30-1946/7/15), Brazil (1969-1994), Israel (1969-1985), Nicaragua (1969-1991), Peru (1969-1990) and Bolivia (1969-1985). On the basis of a generalization of Cagan's model of inflation based on the mechanism of “inflationary expectation” of positive feedbacks between realized growth rate and people's expected growth rate, we find that hyperinflations can be characterized by a power law singularity culminating at a critical time tc. Mizuno et al.'s double-exponential function can be seen as a discrete time-step approximation of our more general non-linear ODE formulation of the price dynamics which exhibits a finite-time singular behavior. This extension of Cagan's model, which makes natural the appearance of a critical time tc, has the advantage of providing a well-defined end of the clearly unsustainable hyperinflation regime. We find an excellent and reliable agreement between theory and data for Germany, Hungary, Peru and Bolivia. For Brazil, Israel and Nicaragua, the super-exponential growth seems to be already contaminated significantly by the existence of a cross-over to a stationary regime.

Central America and Cuba in the new world order

DOE Office of Scientific and Technical Information (OSTI.GOV)

Smith, W.; Gilbert, L.

In Central America and the Caribbean, as in many other parts of the world, military institutions are being forced to define new roles for themselves in the post-Cold War era. In recent times, developments throughout the region, including the dismantling of Panama`s military, the downsizing of the armed forces in El Salvador and Nicaragua, a call by the new Honduran president for military reform and renewed peace talks in Guatemala, suggest that the time may be ripe to reinvigorate earlier regional political organizations and to press for a new round of talks to achieve regional arms control. During the 1980s,more » the ideological struggle between East and West, reignited by the Nicaraguan revolution in 1979, dragged the entire region into conflicts that devastated the isthmus in terms of human lives and economic infrastructure. Indigenous struggles that had developed during the 1970s were suddenly thrust upon the international stage, becoming part of a larger drama between the superpowers. Conflicts in El Salvador, Nicaragua and Guatemala provided impetus for larger armed forces throughout the region. This growth was justified as necessary to defend the state from external intervention and the established order from internal subversion, goals which were seen as complementary.« less

Members of Gammaproteobacteria as indicator species of healthy banana plants on Fusarium wilt-infested fields in Central America

2017-01-01

Culminating in the 1950’s, bananas, the world’s most extensive perennial monoculture, suffered one of the most devastating disease epidemics in history. In Latin America and the Caribbean, Fusarium wilt (FW) caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (FOC), forced the abandonment of the Gros Michel-based export banana industry. Comparative microbiome analyses performed between healthy and diseased Gros Michel plants on FW-infested farms in Nicaragua and Costa Rica revealed significant shifts in the gammaproteobacterial microbiome. Although we found substantial differences in the banana microbiome between both countries and a higher impact of FOC on farms in Costa Rica than in Nicaragua, the composition especially in the endophytic microhabitats was similar and the general microbiome response to FW followed similar rules. Gammaproteobacterial diversity and community members were identified as potential health indicators. Healthy plants revealed an increase in potentially plant-beneficial Pseudomonas and Stenotrophomonas, while diseased plants showed a preferential occurrence of Enterobacteriaceae known for their plant-degrading capacity. Significantly higher microbial rhizosphere diversity found in healthy plants could be indicative of pathogen suppression events preventing or minimizing disease expression. This first study examining banana microbiome shifts caused by FW under natural field conditions opens new perspectives for its biological control. PMID:28345666

Languages have diverse strategies for marking agentivity and number. These strategies are negotiated to create combinatorial systems. We consider the emergence of these strategies by studying features of movement in a young sign language in Nicaragua (NSL). We compare two age cohorts of Nicaraguan signers (NSL1 and NSL2), adult homesigners in Nicaragua (deaf individuals creating a gestural system without linguistic input), signers of American and Italian Sign Languages (ASL and LIS), and hearing individuals asked to gesture silently. We find that all groups use movement axis and repetition to encode agentivity and number, suggesting that these properties are grounded in action experiences common to all participants. We find another feature – unpunctuated repetition – in the sign systems (ASL, LIS, NSL, Homesign) but not in silent gesture. Homesigners and NSL1 signers use the unpunctuated form, but limit its use to No-Agent contexts; NSL2 signers use the form across No-Agent and Agent contexts. A single individual can thus construct a marker for number without benefit of a linguistic community (homesign), but generalizing this form across agentive conditions requires an additional step. This step does not appear to be achieved when a linguistic community is first formed (NSL1), but requires transmission across generations of learners (NSL2). PMID:26740937

Soil bioengineering for risk mitigation and environmental restoration in a humid tropical area

NASA Astrophysics Data System (ADS)

Petrone, A.; Preti, F.

2010-02-01

The use of soil bio-engineering techniques in developing countries is a relevant issue for disaster mitigation, environmental restoration and poverty reduction. Research on the autochthonal plants suitable for these kinds of interventions and on the economic efficiency of the interventions is essential for the dissemination of such techniques. The present paper is focused on these two issues as related to the realization of various typologies of soil bioengineering works in the humid tropics of Nicaragua. In the area of Río Blanco, located in the Department of Matagalpa, soil bioengineering installations were built in several sites. The particular structures built were: drainages with live fascine mattress, a live palisade, a vegetated live crib wall for riverbank protection, a vegetative covering made of a metallic net and biotextile coupled with a live palisade made of bamboo. In order to evaluate the suitability of the various plants used in these works, monitoring was performed, one on the live palisade alongside an unpaved road and the other on the live crib wall along a riverbank, by collecting data on survival rate and morphological parameters. Concerning economic efficiency, we proceeded to a financial analysis of the works. Once the unit price was obtained, we converted the amount into EPP Dollars (Equal Purchasing Power) in order to compare the Nicaraguan context with the European one. Among the species used we found that Gliricidia sepium (local common name: Madero negro) and Tabebuia rosea (local common name: Roble macuelizo) are adequate for soil bioengineering measures on slopes, while Erythrina fusca (local common name: Helequeme) resulted in successful behaviour only in the crib wall for riverbank protection. In comparing costs in Nicaragua and in Italy, the unit price reduction for Nicaragua ranges from 1.5 times (for the vegetative covering) to almost 4 times (for the fascine mattress), using the EPP dollar exchange rate. Our conclusions with
