Prevalencia e incidencia de los principales trastornos endocrinos y metabólicos

How heat waves, ozone and sunlight hours affect endocrine and metabolic diseases emergency admissions? A case study in the region of Madrid (Spain)

BACKGROUND

Studies which analyse the joint effect of acoustic or chemical air pollution variables and different meteorological variables on neuroendocrine disease are practically nonexistent. This study therefore sought to analyse the impact of air pollutants and environmental meteorological variables on daily unscheduled admissions due to endocrine and metabolic diseases in the Madrid Region from January 01, 2013 to December 31, 2018.

MATERIAL AND METHODS

We conducted a longitudinal, retrospective, ecological study of daily time series analysed by Poisson regression, with emergency neuroendocrine-disease admissions in the Madrid Region as the dependent variable. The independent variables were: mean daily concentrations of PM₁₀, PM_2.5, NO₂ and O₃; acoustic pollution; maximum and minimum daily temperatures; hours of sunlight; relative humidity; wind speed; and air pressure above sea level. Estimators of the statistically significant variables were used to calculate the relative risks (RRs).

RESULTS

A statistically significant association was found between the increase in temperatures in heat waves, RR: 1.123 95% CI (1.001-1.018), and the number of emergency admissions, making it the main risk factor. An association between a decrease in sunlight and an increase in hospital admissions, RR: 1.005 95% CI (1.002 1.008), was likewise observed. Similarly, ozone, in the form of mean daily concentrations in excess of 44 μg/m³, had an impact on admissions due to neuroendocrine disease, RR: 1.010 95% CI (1.007-1.035). The breakdown by sex showed that in the case of women, NO₂ was also a risk factor, RR: 1.021 95% CI (1.007-1.035).

CONCLUSION

The results obtained in this study serve to identify risk factors for this disease, such as extreme temperatures in heat waves, O₃ or NO₂. The robust association found between the decrease in sunlight and increase in hospital admissions due to neuroendocrine disease serves to spotlight an environmental factor which has received scant attention in public health until now.

Health care activity at the endocrinology and nutrition outpatient clinics of Castilla-La Mancha (the AACENCAM study)

INTRODUCTION

This study was promoted by Sociedad Castellano Manchega de Endocrinología, Nutrición y Diabetes to ascertain the characteristics of patients seen at the outpatient clinics of endocrinology and nutrition of the Castilla-La Mancha Health Authority and the case mix of diagnoses.

PATIENTS AND METHODS

This was a retrospective, cross-sectional study of the activity of the endocrinology and nutrition outpatient clinics of public hospitals of Castile-La Mancha during 2018. All visits made on 10% of the working days were analyzed. Data collected comprised patient age and sex, whether a first or subsequent had been made, and whether this was face-to-face or not, and up to five diagnoses per visit.

RESULTS

A total of 10,709 visits with a subsequent/first visit ratio of 3.4 were analyzed. Patient age was 52.1?±?18.2 years, and 67.1% were women. Type 2 diabetes mellitus, primary hypothyroidism, thyroid nodular disease, and obesity/overweight were the most common conditions recorded as first diagnosis, accounting for more than half of the total number of visits. Type 1 diabetes mellitus and thyroid cancer were the diagnoses in which the subsequent/first visit ratio was greater. Type 2 diabetes mellitus, obesity, and primary hypothyroidism accounted for almost half of the first visits.

CONCLUSIONS

A wide variety of conditions were seen, some of which are among the most prevalent in the general population, while others are not so prevalent, but are complex and difficult to manage by other specialties. Improved knowledge and analysis of the data should allow for the identification of opportunities for improvement and for the implementation of specific actions.
