RESUMEN
OBJECTIVE: To test whether updated clinical practice guidelines for managing upper respiratory tract infections released in France in November 2011 were associated with changes in national outpatient pediatric antibiotic use. STUDY DESIGN: We performed an interrupted time-series analysis using national antibiotic dispensation data in French children from January 2009 to December 2017 (IQVIA Suivi de la Dispensation Médicale database). We described the overall evolution of antibiotic prescription rates and modeled the changes in the proportion of amoxicillin and the proportion of broad-spectrum antibiotics following the guidelines in 2 age groups (0-5 and 6-14 years old). RESULTS: We analyzed 123 million pediatric antibiotic prescriptions. The most commonly prescribed individual antibiotic agent was amoxicillin (37.7%). Over the study period, the annual antibiotic prescription rate decreased by 33.1% (from 1387 to 928 per 1000 pediatric inhabitants per year), consistently across age groups and major antibiotic agents except for amoxicillin (+14.4%). After the release of the guidelines, we observed a gradual increase in the proportion of amoxicillin (relative change 5 years postintervention of +64.3% [95% CI 51.6-80.1] and +28.4% [21.1-36.2] for children 0-5 and 6-14 years, respectively) concomitantly with a gradual decrease in the proportion of broad-spectrum antibiotics (relative change 5 years postintervention of -26.1% [-29.3, -23.7] and -19.8% [-22.1, -16.0] for children 0-5 and 6-14 years old, respectively). CONCLUSIONS: The 2011 guidelines for upper respiratory tract infections preceded changes in outpatient pediatric antibiotic use at the national level, with a replacement of broad-spectrum antibiotics by amoxicillin.

Background: Ischaemic heart disease (IHD) ranks as the leading cause of death worldwide. Whereas much attention focuses on behavioural and lifestyle factors, less research examines the role of acute, ambient stressors. An unprecedented rise in homicides in Mexico over the past decade and the attendant media coverage and publicity have raised international concern regarding its potential health sequelae. We hypothesize that the rise in homicides in Mexico acts as an ecological threat to security and elevates the risk of both transient ischaemic events and myocardial infarctions, thereby increasing IHD deaths. Methods: We applied time-series methods to monthly counts of IHD deaths and homicides in Mexico for 156 months spanning January 2000 to December 2012. Methods controlled for strong temporal patterns in IHD deaths, the unemployment rate and changes in the population size at risk. Results: After controlling for trend and seasonality in IHD deaths, a 1-unit increase in the logged count of homicides coincides with a 7% increase in the odds of IHD death in that same month (95% confidence interval: 0.04 - 0.10). Inference remains robust to additional sensitivity checks, including a state-level fixed effects analysis. Conclusions: Our findings indicate that the elevated level of homicides in Mexico serves as a population-level stressor that acutely increases the risk of IHD death. This research adds to the growing literature documenting the role of ambient threats, or perceived threats, to security on cardiovascular health.

OBJECTIVES: To examine temporal trends in race-specific neonatal death in California to determine whether the overall decline in mortality attenuated the paradoxical survival advantage of very low birth weight (VLBW; birth weight < 1500 g) non-Hispanic black infants relative to VLBW non-Hispanic white infants. STUDY DESIGN: The data set comprised the California birth cohort file on non-Hispanic black and non-Hispanic white VLBW neonatal mortality for 1989-2004. Logistic regression methods were used to control for potentially confounding maternal characteristics. RESULTS: In 1989 and 1990, non-Hispanic black VLBW infants demonstrated a paradox of lower neonatal mortality (adjusted odds ratio [aOR] = 0.84; 95% confidence interval [CI] = 0.75-0.94). This survival advantage disappeared after 1991, however. In 2003 and 2004, the incidence of neonatal mortality increased in non-Hispanic black VLBW infants but decreased in non-Hispanic white VLBW infants, resulting in a racial disparity (aOR = 1.34; 95% CI = 1.14-1.56). CONCLUSIONS: An initial survival paradox transformed into a disparity. The magnitude of this non-Hispanic black/non-Hispanic white VLBW disparity rose to its highest levels in the last 2 years of the study period. Moreover, the steady mortality increase in VLBW non-Hispanic black VLBW infants since 2001 reversed the secular decline in neonatal mortality in this population. Our findings underscore the need to augment strategies to improve the health trajectory of gestation in non-Hispanic black women.
