La medicina enfrenta el reto de adquirir, analizar y aplicar conocimiento para resolver problemas clínicos complejos. Existen innumerables adelantos que involucran el uso intensivo de la tecnología para realizar correlación de datos necesarios para la toma de decisiones. En este artículo se realiza una estimación de la presencia de diarreas en niños por Rotavirus frente a condiciones climáticas a través del factor bayesiano que, incluye una correlación de Pearson, donde se caracteriza la distribución posterior y se estima el factor de Bayes. Para tal fin se analizan series de datos climático temporales y series de datos de pacientes enfermos con diarreas por rotavirus. El estudio se realiza en el municipio de Pinar del Río, en el periodo comprendido de noviembre de 2018 – mayo 2019. La población susceptible a la enfermedad es de 516 pacientes, para una muestra de 210 niños, con edad de 1 mes de nacido a 5 años de vida y que fueron hospitalizados en el Hospital Pediátrico Pepe Portilla de la provincia de Pinar del Río. Los resultados obtenidos a través de una correlación lineal de Pearson es que existe una correlación significativa muy por debajo del P valor y se plantea al respecto que, en la medida que existe un mayor número de precipitaciones, mayores son los enfermos con diarreas por rotavirus. Posteriormente se calcula el Factor Bayes para corroborar lo planteado; obteniéndose un valor igual a 0.124, resultado que demuestra la existencia de evidencia moderada de que los enfermos con diarreas por rotavirus.
Neonatal and young infant GBS disease can be classified into early-onset disease (EOD, onset during the first 6 days of life), and late-onset disease (LOD, onset between days 7-89 of life). It is estimated that 60.00-90.00 % of EOD occurs on the first day of life [3,4]. In the first week of life, invasive disease may appear early and frequently can cause bacteremia or pneumonia. After this period, transmission can be associated with medical care or community [5]. In most cases, it can manifests clinically as bacteremia, but also as meningitis. Both clinical forms can cause high case-fatality rate (CFR), causing often severe permanent neurological sequel [6]. The epidemiology of GBS disease considerably varies geographically and over time. A recent meta-analysis of worldwide published studies reported a mean global incidence of 0.53/1000 live births and a mean CFR of 9.60 % [7]. GBS is a Gram-positive bacterium, and there are 10 serotypes based on their capsular polysaccharide composition (Ia, Ib, II-IX). The polysaccharide capsule is a major virulence factor contributing to bacterial evasion of phagocytic clearance [8]. Serotype III is the most common invasive isolates and accounts for 30.00-50.00% of EOD and majority of LOD [7,9]. The bacteria colonize the human vagina, upper gastrointestinal and respiratory tract of healthy humans. The entrance door is often not obvious, but may be through the skin, genital, urinary and respiratory tract. Vertical transmission (mother to child) from colonized mothers can lead to invasive disease in their offspring. Later on, it transmission Volume 7 Issue 3-2017
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.
