Effects of Environmental and Socioeconomic Inequalities on Health Outcomes: A Multi-Region Time-Series Study.

The gradual increase in temperatures and changes in relative humidity, added to the aging and socioeconomic conditions of the population, may represent problems for public health, given that future projections predict even more noticeable changes in the climate and the age pyramid, which require analyses at an appropriate spatial scale. To our knowledge, an analysis of the synergic effects of several climatic and socioeconomic conditions on hospital admissions and deaths by cardiorespiratory and mental disorders has not yet been performed in Brazil. Statistical analyses were performed using public time series (1996-2015) of daily health and meteorological data from 16 metropolitan regions (in a subtropical climate zone in South America). Health data were stratified into six groups according to gender and age ranges (40-59; 60-79; and ≥80 years old) for each region. For the regression analysis, two distributions (Poisson and binomial negative) were tested with and without zero adjustments for the complete series and percentiles. Finally, the relative risks were calculated, and the effects based on exposure-response curves were evaluated and compared among regions. The negative binomial distribution fit the data best. High temperatures and low relative humidity were the most relevant risk factors for hospitalizations for cardiovascular diseases (lag = 0), while minimum temperatures were important for respiratory diseases (lag = 2 or 3 days). Temperature extremes, both high and low, were the most important risk factors for mental illnesses at lag 0. Groups with people over 60 years old presented higher risks for cardiovascular and respiratory diseases, while this was observed for the adult group (40-59 years old) in relation to mental disorders. In general, no major differences were found in the results between men and women. However, regions with higher urbanization levels presented risks, mainly for respiratory diseases, while the same was observed for cardiovascular diseases for regions with lower levels of urbanization. The Municipal Human Development Index is an important factor for the occurrence of diseases and deaths for all regions, depending on the evaluated group, representing high risks for health outcomes (the value for hospitalization for cardiovascular diseases was 1.6713 for the female adult group in the metropolitan region Palmas, and the value for hospitalization for respiratory diseases was 1.7274 for the female adult group in the metropolitan region Campo Mourão). In general, less developed regions have less access to adequate health care and better living conditions.

Embarazo de alto riesgo en pacientes con complejo extrofia-epispadias: características uro-ginecológicas y manejo / High risk pregnancy in patients with extrophy-epispadia complex: Uro-gynecological characteristics and management

OBJETIVO: El complejo extrofia-epispadias (CEE) abarca desde las epispadias distales hasta la extrofia de cloaca, con serias repercusiones en la calidad de vida de los pacientes; sin embargo, la cirugía reconstructiva ofrece la oportunidad de llegar a la edad adulta y plantearse la maternidad. El objetivo de este trabajo es valorar las características uro-ginecológicas y los riesgos que presentan las gestantes con CEE. MATERIALES Y MÉTODO: Estudio retrospectivo de 50 pacientes diagnosticadas de CEE y tratadas en un centro de referencia para esta patología, nacidas entre 1968 y 2000. Se revisaron sus historias clínicas y se recogieron todos los datos demográficos, patológicos y ginecológicos. RESULTADOS: 37 pacientes cumplían los criterios de inclusión y de estas 8 lograron 17 embarazos (90% espontáneos y 10% mediante FIV). 10 fueron exitosos (50% a término) y 7 fueron abortos, 87,5% de los cuales fueron en el primer trimestre. La infección urinaria (ITU) fue la complicación más frecuente (41,6%) y la más severa fue la oclusión intestinal. Ninguna de las pacientes presentó deterioro de la función renal durante la gestación o dilatación del tracto urinario superior (TUS) patológica. 62,5% de las pacientes presentaron prolapsos genitales posteriores a los embarazos, 80% de los cuales fueron grado III y IV. 87,5% se encontraban secas en el seguimiento posterior a sus embarazos. CONCLUSIÓN: El embarazo en el CEE es de alto riesgo y es crucial que el seguimiento sea llevado a cabo por un equipo multidisciplinar especializado e integrado para minimizar las complicaciones

OBJECTIVE: The exstrophy-epispadias complex (EEC) ranges from distal epispadias to cloacal exstrophy, with serious repercussions on the quality of life of patients. However, reconstructive surgery offers the opportunity to reach adulthood and consider motherhood. The objective of this work is to assess the uro-gynecological characteristics and the risks that pregnant women have with EEC. MATERIALS AND METHOD: Retrospective study of 50 patients diagnosed with EEC and treated in a reference center for this pathology, born between 1968 and 2000. Their medical records were reviewed and all demographic, pathological and gynecological data were collected. RESULTS: 37 patients have the inclusion criteria and of these 8 achieved 17 pregnancies (90% spontaneous and 10% through IVF). 10 were successful (50% at term) and 7 were abortions, 87.5% of which were in the first trimester. Urinary tract infection (UTI) was the most frequent complication (41.6%) and the most severe was intestinal occlusion. None of the patients presented renal function impairment during the gestation or dilation of the pathological upper urinary tract (UUT). 62.5% of the patients presented genital prolapses after pregnancies, 80% of which were grade III and IV. 87.5% were dry in the follow-up after their pregnancies. CONCLUSION: Pregnancy in the EEC patients is high risk and it is crucial that the follow-up is carried out by a specialized and integrated multidisciplinary team to minimize complications

Calcificaciones cardiovasculares en la enfermedad renal crónica: Potenciales implicaciones terapéuticas / Cardiovascular calcifications in chronic kidney disease: Potential therapeutic implications

La calcificación cardiovascular (CV) es una condición muy prevalente en todos los estadios de la enfermedad renal crónica (ERC) y se asocia directamente a una mayor morbimortalidad CV y global. En la primera parte de esta revisión hemos mostrado cómo las calcificaciones CV son una característica destacada del complejo CKD-MBD (chronic kidney disease-mineral and bone disorders) así como un predictor superior de la evolución clínica de nuestros pacientes. No obstante, es necesario también demostrar que la calcificación CV es un factor de riesgo modificable y con la posibilidad, como mínimo, de poder disminuir su progresión (o al menos no agravarla) con maniobras iatrogénicas. Aunque estrictamente solo se disponga de evidencias circunstanciales, sabemos que el uso de determinados fármacos puede modificar la progresión de las calcificaciones CV, aunque no se ha demostrado un vínculo directo causal sobre la mejoría de la supervivencia. En este sentido, el uso de quelantes del fósforo no cálcicos ha demostrado reducir la progresión de las calcificaciones CV en comparación con el uso liberal de quelantes cálcicos en varios ensayos clínicos aleatorizados. Por otra parte, aunque solo a nivel experimental, los activadores selectivos del receptor de la vitamina D parecen mostrar un mayor margen terapéutico contra la calcificación CV. Finalmente, los calcimiméticos también parece que podrían atenuar la progresión de la calcificación CV en pacientes en diálisis. Mientras se desarrollan nuevas estrategias terapéuticas (p. ej. vitamina K, SNF472…), proponemos que la valoración de las calcificaciones CV puede ser una herramienta usada por el nefrólogo para la toma individualizada de decisiones terapéuticas (AU)

Cardiovascular (CV) calcification is a highly prevalent condition at all stages of chronic kidney disease (CKD) and is directly associated with increased CV and global morbidity and mortality. In the first part of this review, we have shown that CV calcifications represent an important part of the CKD-MBD complex and are a superior predictor of clinical outcomes in our patients. However, it is also necessary to demonstrate that CV calcification is a modifiable risk factor including the possibility of decreasing (or at least not aggravating) its progression with iatrogenic manoeuvres. Although, strictly speaking, only circumstantial evidence is available, it is known that certain drugs may modify the progression of CV calcifications, even though a direct causal link with improved survival has not been demonstrated. For example, non-calcium-based phosphate binders demonstrated the ability to attenuate the progression of CV calcification compared with the liberal use of calcium-based phosphate binders in several randomised clinical trials. Moreover, although only in experimental conditions, selective activators of the vitamin D receptor seem to have a wider therapeutic margin against CV calcification. Finally, calcimimetics seem to attenuate the progression of CV calcification in dialysis patients. While new therapeutic strategies are being developed (i.e. vitamin K, SNF472, etc.), we suggest that the evaluation of CV calcifications could be a diagnostic tool used by nephrologists to personalise their therapeutic decisions (AU)
