    Objectives: To evaluate for any association between time of admission to the PICU and mortality. Design: Retrospective cohort study of admissions to PICUs in the Virtual Pediatric Systems (VPS, LLC, Los Angeles, CA) database from 2009 to 2014. Setting: One hundred and twenty-nine PICUs in the United States. Patients: Patients less than 18 years old admitted to participating PICUs; excluding those post cardiac bypass. Interventions: None. Measurements and Main Results: A total of 391,779 admissions were included with an observed PICU mortality of 2.31%. Overall mortality was highest for patients admitted from 07:00 to 07:59 (3.32%) and lowest for patients admitted from 14:00 to 14:59 (1.99%). The highest mortality on weekdays occurred for admissions from 08:00 to 08:59 (3.30%) and on weekends for admissions from 09:00 to 09:59 (4.66%). In multivariable regression, admission during the morning 06:00-09:59 and midday 10:00-13:59 were independently associated with PICU death when compared with the afternoon time period 14:00-17:59 (morning odds ratio, 1.15; 95% CI, 1.04-1.26; p = 0.006 and midday odds ratio, 1.09; 95% CI; 1.01-1.18; p = 0.03). When separated into weekday versus weekend admissions, only morning admissions were associated with increased odds of death on weekdays (odds ratio, 1.13; 95% CI, 1.01-1.27; p = 0.03), whereas weekend admissions during the morning (odds ratio, 1.33; 95% CI, 1.14-1.55; p = 0.004), midday (odds ratio, 1.27; 95% CI, 1.11-1.45; p = 0.0006), and afternoon (odds ratio, 1.17; 95% CI, 1.03-1.32; p = 0.01) were associated with increased risk of death when compared with weekday afternoons. Conclusions: Admission to the PICU during the morning period from 06:00 to 09:59 on weekdays and admission throughout the day on weekends (06:00-17:59) were independently associated with PICU death as compared to admission during weekday afternoons. Potential contributing factors deserving further study include handoffs of care, rounds, delays related to resource availability, or unrecognized patient deterioration prior to transfer

    <b><i>Background:</i></b> Socioeconomic position (SEP) is an important determinant of health and it is dynamic across the entire lifespan. We sought to investigate the relationship between life-course SEP and chronic kidney disease (CKD) using 3 conceptual models: critical period, pathway and accumulation. <b><i>Methods:</i></b> Cross-sectional analysis of 4,996 participants from The Irish Longitudinal Study on Ageing, a nationally representative cohort of community-dwelling adults aged ≥50 years. We defined childhood and adulthood SEP according to father’s and respondent’s occupation respectively. SEP was categorised as high (reference), intermediate, low and never worked. CKD was defined as a glomerular filtration rate < 60 mL/min/1.73 m<sup>2</sup> estimated from the combination of creatinine and cystatin C. We used logistic regression to estimate the age-adjusted association between SEP and CKD separately in men and women. <b><i>Results:</i></b> Low childhood SEP was strongly associated with CKD in women, after adjusting for adulthood SEP (OR 1.90 [95% CI 1.24–2.92]), supporting the critical period hypothesis. This association was not explained by traditional CKD risk factors. Women who experienced low childhood SEP and whose circumstances improved in adulthood also had increased odds of CKD, further supporting a critical period effect in childhood. There was comparatively less evidence in support of the pathway or accumulation models. We did not observe a statistically significant association between SEP and CKD in men. <b><i>Conclusions:</i></b> Our findings suggest that women exposed to disadvantaged SEP in childhood represent an at-risk group in whom there may be opportunities for identification of CKD and facilitation of health-promoting behaviours from an early age
