“…However, as previously stated, our study may have still been limited by reverse causation due to the population already having diminished kidney function. Still, this design allowed us to obtain measurements of PAHs over time, which is important given their nonpersistence 19 and in contrast to other studies that have investigated impacts on renal function using just one spot urine measurement of PAHs [15][16][17][18] . This study represents the first exploration of serially measured PAHs in relation to kidney function and allowed for a careful examination of these biomarkers over time.…”

“…In contrast, two other cross-sectional studies using NHANES data found associations between urinary PAH metabolites and decreased eGFR (15) and increased albuminuria (16). Two other cross-sectional studies among highly exposed indigenous populations in Mexico reported conflicting results: one found positive associations between PAH metabolites and kidney injury biomarkers, including neutrophil gelatinase-associated lipocalin (NGAL) (17), whereas the other found no such correlation (18). To our knowledge, no longitudinal studies have been conducted on PAH exposure in relation to renal function.…”

Background: Air pollution, which results in the formation of polycyclic aromatic hydrocarbons (PAH), has been identified as a cause of renal function decline and a contributor to chronic kidney disease (CKD). However, the results of cross-sectional studies investigating personal, integrated biomarkers of PAHs have been mixed. Longitudinal studies may be better suited to evaluate environmental drivers of kidney decline. The purpose of this study was to examine associations of serially measured urinary PAH metabolites with clinical and subclinical measures of kidney function over time among children with CKD. Methods: This study was conducted among 618 participants in the CKD in Children study, a cohort study of pediatric CKD patients from the US and Canada, between 2005 and 2015. In serially collected urine samples over time, nine PAH metabolites were measured. Clinical outcomes measured annually included estimated glomerular filtration rate (eGFR), proteinuria, and blood pressure. Subclinical biomarkers of tubular injury (kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL)) and oxidant stress (8-hydroxy-2'- deoxyguanosine (8-OHdG) and F2-isoprostane) were assayed in urine samples. Results: Children were followed over an average of 3.0 years (standard deviation (SD)=1.6) and 2469 study visits (mean=4.0, SD=1.6). Hydroxynaphthalene (NAP) or hydroxyphenanthrene (PHEN) metabolites were detected in >99% of samples and NAP concentrations were greater than PHEN concentrations. PHEN metabolites, driven by 3-PHEN, were associated with increased eGFR and reduced proteinuria, diastolic blood pressure z-score, and NGAL concentrations over time. However, PAH metabolites were consistently associated with increased KIM-1 and 8-OHdG concentrations. Conclusions: Among children with CKD, these findings provoke the potential explanation of reverse causation where renal function affects measured biomarker concentrations even in the setting of a longitudinal study. Additional work is needed to determine if elevated KIM-1 and 8-OHdG excretion reflects site-specific injury to the proximal tubule mediated by low-grade oxidant stress.

“…El segundo grupo de problemas de salud son aquellos ligados a la presencia de contaminantes ambientales en el entorno domiciliar. Se ha documentado la presencia de plaguicidas, metales, hidrocarburos y otras sustancias tóxicas en animales sinantrópicos, agua y en seres humanos, ligando su exposición a los quehaceres cotidianos, los cuales muchas veces se dan en el contexto de las actividades productivas como talleres, manufacturas, artesanías, o por manejo inadecuado de plaguicidas o agroquímicos desarrollados en el huerto familiar o el peridomicilio; representando un importante riesgo para la salud pública y para la sostenibilidad ambiental (Ramírez-Hernández et al, 2018;Pérez-Herrera et al, 2019;Escamilla-López, Ruiz-Piña and Rendón-von Osten, 2020;Díaz de León-Martínez et al, 2021;Perera-Rios et al, 2021).…”

Background: People's peridomicile and home gardens represent a critical bridge for circulating endemic, emerging, and reemerging zoonotic pathogens in the Yucatan region. Objective: to analyze the information on zoonotic diseases documented in the premise and family gardens environment in the Yucatan region and propose an approximation for their prevention and control focusing on a One Health approach. Implications: Proposals based on One Health approach requires the horizontal involvement of social actors, because vertical or government based decisions are not enough to reach health objectives Conclusion: the access to actions based on a One Health approach can directly impact the prevention and control of zoonotic diseases and other environmental health problems.
