Prevalence of children exposed to secondhand smoke at home and in the car in Azores (Portugal)

Article in PressTo identify the prevalence of exposure to secondhand smoke(SHS) at home and in the car among children attending the 4th grade in Azores. Methods:This is across-sectional study that assessed children’s exposure to SHS in a convenience sample of school children attending the 4th grade in all primary schools of Azores.The entire population of 4th graders from all elementary schools in Azores were asked to participate in the study (n=2463) in 2017. A validated self-reported questionnaire was administered to 2092 students who delivered the signed informed consent form. We analyzed frequencies, contingency tables, and performed Chi-square tests. Results: Results showed that 56.1% (95% CI54.0--58.2) children reported having, at least, one smoking parent. Overall exposure to SHS at home was 38.4%(95% CI36.3--40.6), and overall exposure to SHS in the car was 27.6%(95%CI25.8--29.3). Children whose parents were smokers reported being more exposed to SHS at home (63.6%;95% CI58.6--68.3) than children whose parents were non-smokers (32.3%;95% CI30.2--34.6). Conclusion: The results showed that the children’s exposure to SHS in Azores is high and it tends to be higher than the prevalence found in mainland Portugal. Having parents who smoke is a major risk factor for children’s exposure to SHS at home. These data justify a population-wide intervention plan for preventing tobacco consumption and children’s exposure to SHS in Azores.Portuguese national funds through the FCT (Foundation for Science and Technology) within the framework of the CIEC (Research Center for Child Studies of the University of Minho) project under the reference UID/CED/00317/2019

Serum Cystatin C Reflects the Progress of Albuminuria

BackgroundResearch on the relationship between urinary albumin excretion and serum cystatin C in diabetes is restricted to cross-sectional studies. In this study, we investigated how well serial measurements of serum cystatin C level reflect changes in the urinary albumin excretion rate.MethodsWe enrolled and retrospectively collected data on 1,058 participants with type 2 diabetes who were older than 18 years and who had more than 3 years of follow-up with serial measurements of albuminuria and serum cystatin C at an outpatient clinic.ResultsWith the use of a linear mixed model, we found that the albuminuria level for each patient over time corresponded with the annual change in serum cystatin C-based estimated glomerular filtration rate (cysC-eGFR) but did not correspond with the creatinine-based eGFR calculated by the modification of diet in renal disease formula (MDRD-eGFR). The discrepancy in the direction of the trend was smaller with cysC-eGFR than with MDRD-eGFR.ConclusionSerum cystatin C level reflects the trend in albuminuria level more accurately than serum creatinine level in Korean type 2 diabetes mellitus patients

Cystatin C as an Early Biomarker of Nephropathy in Patients with Type 2 Diabetes

This study was done to evaluate clinical usefulness of cystatin C levels of serum and urine in predicting renal impairment in normoalbuminuric patients with type 2 diabetes and to evaluate the association between albuminuria and serum/urine cystatin C. Type 2 diabetic patients (n = 332) with normoalbuminuria (n = 210), microalbuminuria (n = 83) and macroalbuminuria (n = 42) were enrolled. Creatinine, urinary albumin levels, serum/urine cystatin C and estimated glomerular filtration rate (eGFR by MDRD [Modification of Diet in Renal Disease] and CKD-EPI [Chronic Kidney Disease Epidemiology Collaboration] equations) were determined. The cystatin C levels of serum and urine increased with increasing degree of albuminuria, reaching higher levels in macroalbuminuric patients (P < 0.001). In multiple regression analysis, serum cystatin C was affected by C-reactive protein (CRP), sex, albumin-creatinine ratio (ACR) and eGFR. Urine cystatin C was affected by triglyceride, age, eGFR and ACR. In multivariate logistic analysis, cystatin C levels of serum and urine were identified as independent factors associated with eGFR < 60 mL/min/1.73 m2 estimated by MDRD equation in patients with normoalbuminuria. On the other hand, eGFR < 60 mL/min/1.73 m2 estimated by CKD-EPI equation was independently associated with low level of high-density lipoprotein in normoalbuminuric patients. The cystatin C levels of serum and urine could be useful markers for renal dysfunction in type 2 diabetic patients with normoalbuminuria
