Factores predictivos de anemia en gestantes de un área de salud

Introducción: La anemia es un desorden nutricional que afecta con frecuencia, a niños, adultos, lactantes y en especial a las embarazas, constituye un problema de salud en Cuba y el mundo, ha sido relacionado con complicaciones materno perinatales, razón por la cual es importante determinar los factores asociados, para un tratamiento y prevención adecuada. Objetivo: Identificar los factores predictivos de la anemia en las gestantes atendidas en el Policlínico Ramón López Peña. Métodos: Se realizó un estudio analítico observacional, de tipo caso-control, a partir de gestantes diagnosticadas con anemia en cualquier trimestre del embarazo (casos), y otro grupo que no tuvieron esta condición (controles). Se determinó el Odd Ratio, el intervalo de confianza, la prueba de Chi 2 y riesgo atribuible en expuesto porcentual. El análisis de los datos se basó en la construcción de un modelo multivariado (regresión logística multivariable) para identificar los factores predictivos de anemia. Resultados: Hubo un predominio de la anemia ligera (52,9 %) en el tercer trimestre del embarazo (44,1 %). Los ocho predictores que formaron parte del modelo fueron: el embarazo múltiple, la multiparidad, el período intergenésico corto, la adolescencia, la hemorragia de la 1ra y 2da mitad del embarazo, el bajo ingreso económico y el peso deficiente a la captación. El modelo presentó una muy buena discriminación, con un área bajo la curva de 0,826. El estadígrafo correspondiente de la prueba de Hosmer-Lemeshow fue de 0,29. Conclusiones: La edad, el bajo ingreso económico, el peso deficiente a la captación y otros relacionados con la gestación como: el embarazo múltiple, la multiparidad, el período intergenésico corto y las hemorragias, fueron los factores de riesgos predictivos de la anemia gestacional en el Área de Salud.

Introduction: Anemia is a nutritional disorder that frequently affects children, adults, infants and especially pregnant women, it constitutes a health problem in Cuba and the world, it has been related to maternal and perinatal complications, which is why it is important determine the associated factors, for adequate treatment and prevention. Objective: To identify the predictive factors of anemia in pregnant women treated at the Ramón López Peña Polyclinic. Methods: An observational analytical study was carried out, of the case-control type, from pregnant women diagnosed with anemia in any trimester of pregnancy (cases), and another group that did not have this condition (controls). The Odd Ratio, the confidence interval, the Chi 2 test, and attributable risk in percentage exposed were determined. Data analysis was based on the construction of a multivariate model (multivariate logistic regression) to identify predictors of anemia. Results: There was a predominance of light anemia (52.9 %) in the third trimester of pregnancy (44.1 %). The eight predictors that were part of the model were: multiple pregnancy, multiparity, short birth interval, adolescence, hemorrhage in the 1st and 2nd half of pregnancy, low income, and low weight at pregnancy detection. The model presented very good discrimination, with an area under the curve of 0.826. The corresponding statistic for the Hosmer-Lemeshow test was 0.29. Conclusions: Age, low income, deficient weight at pregnancy detection and others related to pregnancy such as: multiple pregnancy, multiparity, short intervals between pregnancies and bleeding, were the predictive risk factors of gestational anemia in the Health Area.

Analysis of anemia in chronic heart failure / 中国医师杂志

Objective To investigate the correlation between the incidence and characteristics of anemia in chronic heart failure population through retrospective analysis of patients hospitalized at the Hunan Provincial People's Hospital.Methods A total of 259 patients who were diagnosed as chronic heart failure (CHF) and hospitalized at the Hunan Provincial People's Hospital from October to November in 2012 was collected,and divided into cardiac function Ⅰ ～ Ⅳ grade,then their clinical characteristics was analyzed.Results (1)Compared with CHF patients without anemia,the creatinine value was significantly higher,the percentage of patients with severe heart failure was significantly higher in the CHF patients with anemia (P＜ 0.05).(2) Logistic regression analysis demonstrated that age (95％ CI:1.123 ～ 3.580,P ＜ 0.05),renal insufficiency (95％ CI:1.320 ～ 4.845,P ＜ 0.05),and cardiac function (95 ％ CI:1.368 ～ 3.385,P ＜ 0.05) in patients with heart failure were important risk factors for anemia.Conclusions Anemia was common in CHF patients.The poorer cardiac function was and the lower hemoglobin was,the higher incidence of anemia was.The patients with anemia had the characteristics of worse renal function and poorer nutritional status compared patients without anemia.Age,renal insufficiency,and cardiac function were important risk factors for anemia.

Massive septic pelvic osteolysis following revision total hip arthroplasty in a patient with sickle cell anemia: clinical presentation and review of the literature.

Total hip arthroplasty (THA) performed in patients with osteonecrosis, caused by sickle cell disease, carries a higher risk of medical and orthopedic complications, than those observed after THA for osteonecrosis related to other conditions. We report such a case of a male patient, who underwent one-stage revision hip arthroplasty due to septic cup loosening after primary cementless THA and later developed severe septic osteomyelitis of the ipsilateral hemipelvis that had a fatal outcome. The relative literature regarding loosening and infection after THA in patients with sickle cell disease is thoroughly reviewed.
