West Nile virus (WNV) was probably introduced in southern and northern Mexico from the USA in two independent events. Since then, WNV activity has been reported in several Mexican states bordering the USA and the Gulf of Mexico, but disease manifestations seen there in humans and equids are quite different to those observed in the USA. We have analysed WNV seroprevalence in asymptomatic, unvaccinated equids from two Mexican states where no data had been previously recorded. WNV IgG antibodies were detected in 31.6% (91/288) of equine sera from Chiapas and Puebla states (53.3% and 8.0%, respectively). Analysis by plaque reduction neutralization test (PRNT) showed good specificity (99.4%) and sensitivity (84.9%) with the ELISA results. Further analyses to detect antibodies against three different flaviviruses (WNV, St Louis encephalitis virus, Ilheus virus) by haemagglutination inhibition (HI) tests on a subset of 138 samples showed that 53% of the 83 HI-positive samples showed specific reaction to WNV. These data suggest continuous expansion of WNV through Mexico.
predictors of non-conventional laparoscopic approach to leiomyoma hysterectomy. Our findings suggest that there is a differential access to LH procedures among the US population which may be, in part, a result of racial and socioeconomic differences and centralization of laparoscopy services in urban areas.
Adolescent pregnancies are more likely to occur in poor communities, commonly driven by lack of education and employment opportunities. We aimed to estimate the subdermal implant discontinuation rate and to establish the factors associated with the discontinuation of long-acting reversible contraceptive (LARC) methods in a cohort of poor women in the Caribbean region of Colombia. A retrospective cohort study of LARC method use through review of administrative record data was conducted. A population of 2,192 adolescents and young women between 10-24 years old enrolled in the "SER JOVEN" program and who received subdermal implants between 2015-2018 was considered for eligibility. This program is for young people affiliated to a health care company in the Caribbean region of Colombia. We realized a follow-up time-person of the retrospective cohort, and we estimated the incidence of discontinuation of the subdermal implant at six months, one year, two years, and three years. Kaplan-Meier estimator for survival curves, and Cox proportional hazard model were used to ascertain factors associated with method discontinuation risk. A p-value <0.050 was considered significant. A total of 2,192 women were selected with a mean (standard deviation -SD) age of 19.4 (2.8) years and a mean duration of use of subdermal implant of 2.6 (0.8) years. We estimated the subdermal implant discontinuation rate at six months in 0.7% [CI95% 0.3-1.1], a year later in 1.5% [CI95% 1-2], two years later in 2.1% [CI95% 1.5-2.7] and finally at three years in 2.2% [CI95% 1.6-2.8]. Women who stated they have children at baseline were about 70% less risk to discontinue subdermal implants (HR: 0.3 [CI95% 0.1 -0.8]). Adolescent pregnancy is a public health problem, and it is an important cause of poverty and illness. Then, the use of subdermal implants is an effective alternative to prevent unintended pregnancies.
To identify the characteristics and risk factors of malnourished children age ≤ 24 months. Methods: A case-control study was conducted at two clinics in Cartagena, Colombia. WHO reference populations for weight-for-height and height-for-age Z-scores were utilized to determine acute and chronic malnutrition. Cases are children with mild, moderate, or severe malnutrition, determined by a Z-score < -1SD; controls are children with Z-scores between -1SD and +2SD. Cases were recruited between August 2014 and October 2015. Chart review and in-person questionnaires were used to gather information on the child's age, height, weight, birth weight and gestational age, maternal characteristics, socioeconomic factors, and household characteristics. Odds Ratios with 95% CI were estimated. Results: Of the total 481 children recruited, 71% had malnutrition, 53% are male and have a median age of 10.93 (SD± 6.57) months, 86% pertain to socioeconomic stratum
To identify associated factors to the control of blood pressure (BP), low-density lipoprotein cholesterol (LDL) and glycated hemoglobin (hba1c) in a low-income population from the Caribbean region of Colombia, enrolled in "De todo corazón -DTC" program between 2013-2018
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
