A cross-sectional study was carried out in four indigenous communities of Costa Rica to detect presence and prevalence ofBabesia caballiandTheileria equiand to investigate factors associated with presence of these hemoparasites. General condition of horses (n=285) was evaluated, and hematocrits and hemoglobin were determined from blood samples of 130 horses, which were also analyzed using blood smears, nested polymerase chain reaction (PCR), and immunosorbent assay (c-ELISA). The general condition of the horses (n=285) in terms of their body and coat was between regular and poor, and hematocrit and hemoglobin average values were low (19% and 10.65 g/dL, resp.). Erythrocyte inclusions were observed in 32 (24.6%) of the samples. Twenty-six samples (20.0%) gave positive results forB. caballiand 60 (46.2%) forT. equi; 10 horses (7.7%) showed mixed infection, when analyzed by PCR. Using c-ELISA, it was found that 90 (69.2%) horses had antibodies againstB. caballiand 115 (88.5%) againstT. equi, while 81 (62.3%) showed mixed reactions. There were no factors associated with the presence ofB. caballiandT. equi. These results contrast with results previously obtained in equines in the Central Valley of Costa Rica.

Abstract Objective This work aims to evaluate the factors associated with Streptococcus pneumoniae nasopharyngeal colonization and antimicrobial susceptibility among pediatric outpatients in southwestern Colombia, 2019. Methods A cross-sectional study was performed using survey-based interviews and the collection of nasopharyngeal-swab specimens for microbiological characterization and antimicrobial susceptibility testing. Logistic regression analyses were performed for factors associated with nasopharyngeal carriage. Results A total of 452 children under the age of 5 years were examined in which 41.8% carried S. pneumoniae. Higher pneumococcal carriage frequencies were observed among participants aged <2 years and in individuals belonging to indigenous communities, which were lacking established pneumococcal-conjugated vaccine-10 immunization schemes. Additionally, children attending childcare institutions were also highly colonized by pneumococci. S. pneumoniae showed 57.7% nonsusceptibility to benzyl-penicillin (meningitis-cut); 45.5% intermediate-sensitivity to benzyl-penicillin (oral-cut) and 21.7% to cefotaxime; and resistance to erythromycin (40.7%), tetracycline (36.0%), trimethoprim/sulfamethoxazole (24.9%), clindamycin (24.3%), and ceftriaxone (27.0%). Conclusion The 41.8% of participants carrying S. pneumoniae show a scenario with the presence of multidrug and extensively drug-resistant strains, which constitutes important reservoirs of bacterial transmission by children aged <5 years in Colombia, leading to an onset of pneumococcal diseases. Hence, there is an urgent need to expand conjugate pneumococcal immunization in the community and ensure compliance with established immunization schedules.

Factors Associated

This article has 3 main objectives: (1) to assess the prevalence of child labor in Colombia, (2) to identify factors associated with child labor, and (3) to determine whether social protection programs have an association with the prevalence of child labor in the country. Using a cross-sectional study with data from the Colombian Demographic and Health Survey 2010, a working child was defined as a child who worked during the week prior to the survey in an activity other than household chores. Through descriptive statistics, bivariate analysis, and multivariate regressions, it was found that child labor was associated with gender (boys were more likely to work), older age, ethnicity (children from indigenous communities were more likely to be workers), school dropout, disability (children with disabilities were less likely to be working), subsidized health social security system membership, and lower number of years of mother’s schooling. Furthermore, the results of this study suggest that children beneficiaries of the subsidy Familias en Acción were less likely to be working and that social protection programs were more effective to reduce child labor when targeting the lowest wealth quintiles of the Colombian population.

Blood Smear Examination

A cross-sectional study was carried out on 50 N’ Dama cattle and 35 equids blood samples from Republic of Guinea and Punjab, India, respectively to assess the level of exposure to obligatory haemoprotozoa Theileria equi and Trypanosoma evansi by 18S rRNA gene based primary and nested polymerase chain reaction (nPCR) and RoTat1.2 based card agglutination test (CATT), and to investigate risk factors associated with the infection. Blood smear examination revealed the prevalence rate of 6% (95% CI = 2.06-16.22) for Trypanosoma spp. in N’dama cattle and 5.7% for T. equi in equids. In equids, 17.14% (95% CI = 8.10-32.68) samples showed positive titer by CATT. Primary PCR showed 5.71% (95% CI = 1.58-18.8) infection and on the other hand nested PCR depicted 20% (95% CI = 10.04-35.89) T. equi infection. Moreover, only 8.57% (95% CI = 2.96-22.38) prevalence of T. evansi was recorded by T. evansi based multiplex PCR. PCRs revealed higher risk of infectionof both T. equi (OR = 5.28, 95% CI = 0.68-49.81) and T. evansi (OR = 3.33, 95% CI = 0.20-104.83) in the farms where proper deworming/vaccination schedule was not followed. The risk factor associated with the type of host species had an odds ratio (OR) of 5 (95% CI = 3.90-74.33) for donkeys/mules versus horses for T. equi infection. This group was also at higher risk of infection with OR of 4.8 (95% CI = 0.12-124.47) for T. evansi. The present exploration brings out a variety of commodities at risk of infectivity pertaining to trypanosomosis and theileriosis calculated by different PCRs assay.

Baseline Characteristics

Background: Hyponatremia is associated with unfavorable outcomes in many cases. The mainstay of hyponatremia treatment depends on its symptoms and etiology. However, etiologies, clinical manifestations, and factors associated with severe symptomatic hyponatremia have been rarely reported. Objective: To analyze and report etiologies, clinical manifestations, and factors associated with severe symptomatic hyponatremia. Materials and Methods: In the present cross-sectional study, the authors enrolled hospitalized patients with hyponatremia who had consulted a nephrologist between October 1, 2017, and October 31, 2018. Their baseline characteristics and clinical manifestations were recorded. Etiologies were confirmed by the attending nephrology staff. Factors associated with severe symptomatic hyponatremia were evaluated using logistic regression analysis. Results: One hundred patients were included in this study. The syndrome of inappropriate antidiuresis (SIAD), hypovolemia, and hydrochlorothiazide use were the leading hyponatremia etiologies. Hyponatremia etiologies differed between patients with community-acquired hyponatremia (n=50) and those with hospital-associated hyponatremia (n=50). Patients with communityacquired hyponatremia were older, presented with a higher frequency of severe symptomatic hyponatremia, and showed lower SNa-levels. Low SNa-levels were significantly associated with severe symptomatic hyponatremia (p=0.014). Conclusion: Hyponatremia remains an important health problem. SIAD, hypovolemia, and hydrochlorothiazide use are among the leading etiologies of hyponatremia. Low SNa-levels are associated with severe symptomatic hyponatremia; thus, physicians should pay close attention to low SNa-levels in hospitalized patients.

Stroke Subtypes

Background: Stroke is a great public health problem in Ethiopia. According to reports, in-hospital stroke mortality was estimated to be 14.7% in Ethiopia. Despite this, in this country researches done on factors associated with stroke sub-types were inadequate. Objective: To assess the Characteristics and risk factors associated with stroke sub-types among patients admitted to JUMC. Methods and materials: A retrospective cross sectional study was conducted from May 2017 to May 2018 in stroke unit of Jimma University Medical Center. A total of 106 medical charts of patients diagnosed with stroke were reviewed. Checklist comprising of relevant variables was used to collect data. SPSS version 21 was employed for data entry and analysis. Chi-square test was used to point-out association and difference among stroke sub-types. The data was presented using text, tables and figures. Result: From a total of 106 patients, 67(63.2%) were men. The mean ± SD of age was 52.67±12.46 years, and no significant association was found. Of all the patients, 59(55.6%) had ischemic strokes and 47(44.4%) had hemorrhagic strokes. The most common risk factor in the patients was alcohol use with a prevalence of 69.9%. Of all the risk factors, only sex, cigarettes smoking and dyslipidemia were significantly associated to sub-types of stroke. Conclusion: Ischemic stroke was the most common subtype of stroke. Sex of patient, cigarette smoking and dyslipidemia are significantly associated with the two stroke subtypes.
