- ObjectiveTo 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.DesignCross-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.SettingLos Cuatro Santos area, rural Nicaragua.Subjects A total of 1371 children 0–35 months of age.ResultsChildren 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.ConclusionsWhile 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.

- Giardiasis is a major problem in León, Nicaragua, yet despite this no data are available regarding the prevalence of different Giardia genotypes in this area. To address this question, a molecular analysis of Giardia isolates from humans and dogs living in the same area in León, Nicaragua was performed. Giardia isolates from 119 Nicaraguan patients and 8 dogs were successfully genotyped using single and/or nested beta-giardin PCR with subsequent restriction length fragment polymorphism (RFLP) analysis. The analyses of human samples yielded 94 (79%) assemblage B isolates and 25 (21%) assemblage A isolates. Only the non-human-associated assemblages C and D were found in the dog samples. Sixteen isolates with assemblage A pattern, 26 isolates with assemblage B pattern and all dog isolates were further characterized by sequencing the nested beta-giardin PCR product and by molecular analyses of the glutamate dehydrogenase (gdh) gene. Within the study area the assemblage A isolates were highly genetically homogenous, showing only sub-genotypes A2 (n=3) or A3 (n=13) at the beta-giardin locus and AII only at the gdh locus while assemblage B showed a high genetic polymorphism at both loci. Seven different sub-genotypes were identified within 13 of the sequenced assemblage B beta-giardin isolates. The remaining 13 sequenced assemblage B-isolates appeared to contain several different variants of the beta-giardin gene since the chromatograms displayed one to seven double peaks. The gdh sequences showed an even higher polymorphism since only 2 of 26 assemblage B isolates were without double peaks. Two mixed infections between assemblage A and B were found when the gdh gene was analyzed. Polymorphisms were also observed in the dog-associated assemblages C and D, but to a lesser extent than in assemblage B.

- BackgroundChikungunya infections range from subclinical infection to debilitating arthralgia and to chronic inflammatory rheumatism. Tumor necrosis factor (TNF) α, DC-SIGN (dendritic cell–specific intercellular adhesion molecule 3–grabbing nonintegrin), Toll-like receptor (TLR) 3, and blood groups have been directly or indirectly implicated in the susceptibility and pathogenesis of chikungunya.MethodsTo test the hypothesis that polymorphisms in genes coding for these molecules determine clinical outcomes of chikungunya infection, a retrospective case-control study was performed in León, Nicaragua. The study included 132 case patients and 132 controls, matched for age, sex and neighborhood. Case patients had clinical symptoms of chikungunya, which was diagnosed by means of polymerase chain reaction. Controls were individuals not reporting abrupt presentation of clinical chikungunya-like symptoms. Polymorphisms were identified by TaqMan single-nucleotide polymorphism genotyping assays.ResultsAfter adjustment for sociodemographic risk factors, chikungunya disease was associated with polymorphism in DC-SIGN and TLR3 genes (odds ratios, 5.2 and 3.3, respectively), and TNF-α with reduced persistent joint pain (0.24). Persistent joint pain was also associated with age, female sex and other comorbid conditions. Most interestingly, the Lewis-negative phenotype was strongly associated with both symptomatic chikungunya and immunoglobulin G seropositivity (odds ratios, 2.7, and 3.3, respectively).ConclusionThis study identified polymorphisms in DC-SIGN, TLR3, and TNF-α genes as well as Lewis-negative phenotype as risk factors for chikungunya infection and disease progression.

- Information about norovirus (NoV) infections in Central America is limited. Through a passive community and hospital pediatric diarrhea surveillance program, a total of 542 stool samples were collected between March 2005 and February 2006 in León, Nicaragua. NoV was detected in 12% (65/542) of the children; of these, 11% (45/409) were in the community and 15% (20/133) were in the hospital, with most strains (88%) belonging to genogroup II. NoV infections were age and gender associated, with children of <2 years of age (P < 0.05) and girls (P < 0.05) being most affected. Breast-feeding did not reduce the number of NoV infections. An important proportion (57%) of NoV-infected children were coinfected with diarrheagenic Escherichia coli. A significant proportion (18/31) of NoV-positive children with dehydration required intravenous rehydration. Nucleotide sequence analysis (38/65) of the N-terminal and shell region in the capsid gene revealed that at least six genotypes (GI.4, GII.2, GII.4, GII.7, GII.17, and a potentially novel cluster termed "GII.18-Nica") circulated during the study period, with GII.4 virus being predominant (26/38). The majority (20/26) of those GII.4 strains shared high nucleotide homology (99%) with the globally emerging Hunter strain. The mean viral load was approximately 15-fold higher in children infected with GII.4 virus than in those infected with other G.II viruses, with the highest viral load observed for the group of children infected with GII.4 and requiring intravenous rehydration. This study, the first of its type from a Central American country, suggests that NoV is an important etiological agent of acute diarrhea among children of <2 years of age in Nicaragua.

- Although injuries constitute a major public health problem worldwide, the magnitude and nature of this problem is difficult to establish in low-income settings due to the lack of valid and representative data. In Nicaragua, several parallel studies have been carried out attempting to assess levels and patterns of injury using various sources of information. The objective of this study was to describe the magnitude and profile of moderate and severe injuries in a well-defined community in Nicaragua. The study was conducted using a household-based survey design. Randomized cluster sampling provided information from 10,797 households (63,886 inhabitants). The outcomes included fatal and non-fatal injuries registered during a recall period of 6 weeks. Seven percent of all. injuries were classified as moderate or severe. The estimated annual incidence rate of moderate/severe injuries was 27.6 per 1000 [95% confidence intervals (CI): 26.4-29.2], white the mortality and impairment rates were 108.9 (95% CI: 83.5-134.4) and 95.3 (95% CI: 71.4-119.2) per 100,000 inhabitants, respectively. Home and traffic areas were the main environments associated with injury occurrence. The most affected groups were the elderly, children and mates. No differences were found between urban and rural areas. Only 9% of all cases, including minor injuries, sought hospital treatment. The main causes of non-fatal injuries were falls, traffic and cuts, whereas fatalities were largely associated with intentional injuries. For every death due to injury, there was one permanent disability, 25 moderate/severe injuries and 354 minor injuries. This study provides a broad description of injury magnitudes and patterns in a defined Nicaraguan community, and demonstrates the aggregate injury pyramid of the same community. It also identifies the issue of severity and concludes with a recommendation to apply different criteria of severity. Our results support the call for a careful evaluation of injury data sources and severity scores when planning injury prevention programmes.

- 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 amp;lt;= 7 years with AGE from 6 hospitals in Nicaragua (n = 538), and 3 community clinics (n = 919) and households (n = 333) in Leon, 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.

- This situational analysis study aims to position the discourses that young Nicaraguan women use in their understanding of femininities, male intimate partner violence (IPV), and men's sexual violence toward women (SA). Eight focus group discussions with a total of 59 women were conducted. Positional maps were used to display the data. The findings show a dominant discourse that portrays femininity as enacting attributes habitually bestowed to men such as independence and agency, while still upholding key patriarchal conceptions (respectability) limiting women's agency. Tolerance of IPV and SA by nonpartners varies depending on women's perceived respectability and agency. Most important, we identified a pro-women's rights resistance discourse that constructs femininity and advocates nonviolence from a human rights perspective.

- OBJECTIVES: To estimate the cumulative incidence rate of acute pesticide poisoning in the year 2000 among Nicaraguan subjects over 15 years of age. METHODS: Data on pesticide exposure and health effects were assessed in a nationally representative survey. Based on self-reported cases, we estimated the 1-year incidence rate and the number of expected cases of acute pesticide poisonings in Nicaragua. RESULTS: Among the 3169 survey respondents, we identified 72 persons who self-reported one episode of acute pesticide poisoning in 2000. Of these, 65 cases (90%) were related to occupational exposure, five (7%) to domestic exposure and two (3%) to intentional exposure. The cumulative incidence rate/100 individuals of pesticide poisonings in Nicaragua in 2000 was 2.3 (95% CI 1.7 to 2.8). This corresponds to 66 113 cases (95% CI 51 017 to 81 210). The highest rate was found among males in rural areas, particularly among farmers and agricultural workers. CONCLUSION: This study demonstrates an extremely high risk of acute pesticide poisoning in Nicaragua. Considering this, comprehensive measures should be implemented to reduce adverse health effects.
