Ductus venosus as a marker of fetal growth in first trimester in a population of Colombian pregnant women / Ductus venoso como marcador de crecimiento fetal en primer trimestre en una población de gestantes colombianas

Abstract Objectives: to evaluate the relationship between the ductus venosus (DV) and the variables of fetal growth in the first trimester in a Colombian pregnant population. Methods: a descriptive cross-sectional study was carried out with secondary data obtained from a multicenter study.526 patients were included between weeks 11 and 14 for gestational ultrasound follow-up attended in three health care institutions in Bogotá, Colombia, between May 2014 and October 2018. A bivariate descriptive analysis was carried out where the relationship between the characteristics of the DV in the first trimester and ultrasound findings. Results: the flow wave of the DV in the first trimester was normal in the entire sample, with a pulsatility index of the ductus venosus (DVPI) of 0.96±0.18. In addition, a negative correlation was found between the crown-rump length (CRL) and the DVPI (p<0.05). Conclusion: there is a relationship between the DVPI regarding the CRL, indicating an interest in this early marker in relation to fetal growth alterations; however, more studies are required to determine the usefulness of this variable with respect to fetal growth.

Resumen Objetivos: evaluar la relación entre el ductus venoso (DV) y las variables del crecimiento fetal en primer trimestre en una población de gestantes colombianas. Métodos: se realizó un estudio transversal descriptivo con datos secundarios obtenidos de un estudio multicéntrico. Se incluyeron 526 pacientes entre las semanas 11 a 14 para seguimiento ecográfico gestacional atendidas en tres instituciones prestadoras de salud en Bogotá, Colombia, entre mayo del 2014 y octubre del 2018. Se realizó un análisis descriptivo bivariado donde se evaluó la relación entre las características del DV en primer trimestre y los hallazgos ecográficos. Resultados: la onda de flujo del DV en primer trimestre fue normal en la totalidad de la muestra, con un índice medio de pulsatilidad del ductus venoso (IPDV) de 0,96±0.18. Se encontró una correlación negativa entre la longitud cefalocaudal (LCC) y el IPDV (p<0.05). Conclusión: existe una relación entre el IPDV respecto a la LCC, señalando un interés de este marcador temprano en relación con las alteraciones del crecimiento fetal, sin embargo, se requieren más estudios para determinar la utilidad entre esta variable respecto al crecimiento fetal

Biometry and pathological ultrasound findings in multiple pregnancies / Características ecográficas y hallazgos patológicos en embarazos múltiples

Resumo Objectives: to determine the prevalence of pathological findings according to the type of chorionicity in pregnancies in two institutions in Bogotá, Colombia. Methods: descriptive, retrospective, cohort study. Biometric variables were calculated, and pathological findings were evaluated according to the type of chorionicity in multiple pregnancies. Statistical characterization was performed with absolute frequencies, calculation of relative frequencies in qualitative variables, standard deviation measures, median and interquartile range. In addition, a descriptive analysis of the information was carried out. Results: 528 studies were carried out in 141 pregnant women, 98.5% (n = 139) twins and 1.4% (n = 2) triplets. A prevalence of 35.4% of fetal complications was calculated. The most frequent was fetal growth restriction (p=0.37). According to each type of chorionicity, fetal growth restriction was presented in 50% (1/2) of the trichorionics, 16.6% (7/42) of the monochorionics, and 11.3% (11/97) of the dichorionics. Conclusion: fetal growth restriction was the most common finding, both in trichorionics, monochorionics and dichorionics pregnancies.

Resumen Objetivos: el objetivo del estudio fue determinar la prevalencia de los hallazgos patológicos ecográficos en embarazos múltiples de acuerdo con la corionicidad en dos instituciones en Bogotá-Colombia. Métodos: estudio de cohorte, descriptivo, retrospectivo. Las variables biométricas realizadas y los hallazgos patológicos se evaluaron de acuerdo con el tipo de embarazo gemelar.

Además, se realizó análisis descriptivo de la información. Resultados: se realizaron 528 estudios en 141 gestantes, encontrando 98,5% (n=139) gemelares y 1,4% (n=2) triples. Se calculó una prevalencia de 35,4% de complicaciones fetales siendo más frecuente la restricción del crecimiento fetal (p=0,37). Según la corionicidad, esta complicación se presentó en 50% (1/2) de los tricoriónicos, 16,6% (7/42) de los monocoriónicos y 11,3% (11/97) de los dicoriónicos. Conclusión: la restricción del crecimiento fetal fue el hallazgo más común en los embarazos múltiples en la población estudiada.

Efecto producido por la población institucionalizada en la estimación del riesgo de mortalidad en áreas pequeñas de Euskadi (España) / Effect of the population in collective dwellings on small-area mortality risk estimation in the Basque Country region (Spain)

OBJETIVO: Cuantificar el efecto que tiene la inclusión de la población institucionalizada en la estimación del riesgo de mortalidad en las secciones censales de Euskadi (España) para las principales causas de mortalidad en el periodo 1996-2003. MÉTODO: Estudio ecológico transversal por áreas pequeñas. Se analizaron las principales causas de mortalidad y por sexo. RESULTADOS: Al analizar el efecto general que tiene en todas las secciones con población institucionalizada se ha visto que no hay apenas ningún efecto reseñable en hombres ni en mujeres. En cambio, cuando se han seleccionado las áreas geográficas donde la población institucionalizada supone un porcentaje importante, más del 10% de la población de esa área, sí se ha observado un efecto incrementando la estimación del riesgo de mortalidad. CONCLUSIONES: El efecto que tiene la inclusión de la población institucionalizada se ve claramente en aquellas causas de mortalidad relacionadas con una mayor dependencia o fragilidad, y por lo tanto con estar en una residencia de personas mayores, como son las demencias y la enfermedad de Alzheimer, y la enfermedad pulmonar obstructiva crónica, sobrestimando el riesgo de mortalidad en torno a un 8% y un 4%, respectivamente, en esas áreas

OBJECTIVE: To quantify the effect of the inclusion of the population in collective dwellings on the estimation of mortality risk in the census areas of the Basque Country (Spain) for the main causes of mortality in the period 1996-2003. METHOD: Small-area ecological cross-sectional study. The main causes of mortality by sex were analyzed. RESULTS: When the general effect on all areas with a a population in collective dwellings was analyzed, hardly any noticeable effect was seen on either men or women. On the other hand, an effect was found when selecting the areas where the population in collective dwellings is more than 10% of the area's population. CONCLUSIONS: The effect of the inclusion of the population in collective dwellings clearly seen in causes of mortality, such as dementia and Alzheimer's disease, and in chronic obstructive pulmonary disease, related to greater dependence or frailty, and therefore related to being in a nursing or elderly persons' home, over-estimating the risk of mortality by approximately 8% and 4%, respectively, in these geographical areas

Dementia-related neuropsychiatric symptoms: inequalities in pharmacological treatment and institutionalization.

BACKGROUND: Dementia-related neuropsychiatric symptoms (NPS) are the main determinant of family stress and institutionalization of patients. This study aimed to identify inequalities by gender and socioeconomic status in the management of NPS in patients diagnosed with dementia. METHODS: An observational study was carried out to study all the cases of dementia in the corporate database of the Basque Health Service (29,864 patients). The prescription of antipsychotics and antidepressants and admission to a nursing home were used to establish the presence of NPS. The socioeconomic status of individuals was classified by a deprivation index. Logistic regressions were used to identify drivers for drug prescriptions and institutionalization. RESULTS: NPS are poorly recorded in the clinical databases (12%). Neuropsychiatric symptoms were severe enough in two thirds of patients with dementia to be treated with psychoactive medication. Institutionalization showed an increase from those who did not receive medication to those who had been prescribed antidepressants (OR: 1.546), antipsychotics (OR: 2.075) or both (OR: 2.741). The resulting inequalities were the increased prescription of antidepressant drugs in women and more nursing-home admissions for women who were the least socioeconomically deprived and men who were the most deprived. CONCLUSIONS: In large clinical databases, psychoactive drugs prescriptions can be useful to underscore the considerable burden of dementia-related NPS. Specific tools are needed to monitor social and health care programs targeted to dementia-related NPS from a population perspective. Programs aimed at reducing the family burden of care of dementia patients at home become the key elements in reducing inequalities in these patients' care. Socioeconomic status is the most important driver of inequality, and gender inequality may simply be hidden within the social environment. Integrated programs boosting the continuity of care are an objective for which compliance could be measured according to the NPS coding in the electronic health record.

Estimación de indicadores de salud en áreas pequeñas a partir de datos de la Encuesta de Salud de Euskadi / Small area estimation of health indicators based on data from the Basque Country Health Survey

Las encuestas de salud son una herramienta clave para la toma de decisiones en políticas de salud y para la planificación de los servicios de salud. El uso de métodos estadísticos para áreas pequeñas que utilizan información de diferentes ámbitos geográficos puede resultar útil para estimar indicadores de salud a una escala geográfica menor que la originalmente considerada en el diseño de una encuesta

Health surveys are a key tool for decision-making in health policies and health services planning. The use of small-area statistical methods that use information at different geographic levels may be useful for estimating health indicators at a lower geographical level than originally considered in the survey design

Gender and socioeconomic inequalities in the implementation of the Basque programme for multimorbid patients.

BACKGROUND: The aim of our study was to increase awareness of the relevance of the implemented programmes to inequity of access and inequality of health by analyzing the impact of a patient-centred strategy for multimorbid patients. METHODS: This retrospective study compared the 2014 multimorbid patient group (intervention group) with its 2012 analogue (control group), before the Department of Health of the Basque Country launched the strategy for managing disease chronicity. Inequalities in healthcare access were represented by differences in the inclusion of patients in the programme and in contacts with primary care (PC) services by gender and socioeconomic status (measured by deprivation index by census track). Likewise, differences in hospital care represented inequalities in health outcomes. Generalized linear models were used to analyze relationships among variables. A propensity score by a genetic matching approach was used to minimize possible selection bias. RESULTS: At baseline, women had less probability of being eligible for the programme. No clear patterns were seen in resource consumption in PC. The probability of hospitalization was higher for men and increased according to socioeconomic status. The implementation of the programme yielded more contacts with PC services in all groups and a reduction in hospitalizations, especially among men and the most socioeconomically deprived patients. CONCLUSION: The patient-centred, integrated-care intervention launched by the Department of Health of the Basque Country might have reduced some gender and socioeconomic inequalities in health outcomes, as it avoided more hospitalizations in subgroups that presented with more episodes of decompensation in the reference year.

Protocolo del estudio sobre el efecto de la crisis económica en la mortalidad, la salud reproductiva y las desigualdades en salud en España / Study protocol on the effect of the economic crisis on mortality and reproductive health and health inequalities in Spain

Se presenta el protocolo de los dos subestudios sobre el efecto de la crisis económica en la mortalidad, la salud reproductiva y las desigualdades en salud en España. Subestudio 1: describir la evolución de la mortalidad y la salud reproductiva entre 1990 y 2013 mediante un estudio longitudinal ecológico en las comunidades autónomas. Se analizarán los cambios producidos por la crisis económica en la tendencia de los indicadores de mortalidad y salud reproductiva utilizando datos panel (17 comunidades autónomas por años de estudio) y ajustando modelos de Poisson de efectos aleatorios. Subestudio 2: analizar las desigualdades según la privación socioeconómica en la mortalidad y en la salud reproductiva en varias zonas de España. Se realizará un estudio ecológico de tendencias en el cual se analizará la precrisis (1999-2003 y 2004-2008) y la crisis (2009-2013). Se ajustarán modelos de efectos aleatorios según Besag York y Mollié para estimar los indicadores de mortalidad y de salud reproductiva suavizados en secciones censales (AU)
