Temperature-mortality associations by age and cause: a multi-country multi-city study.

Background: Heterogeneity in temperature-mortality relationships across locations may partly result from differences in the demographic structure of populations and their cause-specific vulnerabilities. Here we conduct the largest epidemiological study to date on the association between ambient temperature and mortality by age and cause using data from 532 cities in 33 countries.

Methods: We collected daily temperature and mortality data from each country.

Grouped mixtures of air pollutants and seasonal temperature anomalies and cardiovascular hospitalizations among U.S. Residents.

Background: Air pollution is a recognized risk factor for cardiovascular disease (CVD). Temperature is also linked to CVD, with a primary focus on acute effects. Despite the close relationship between air pollution and temperature, their health effects are often examined separately, potentially overlooking their synergistic effects.

Additive effects of 10-year exposures to PM and NO and primary cancer incidence in American older adults.

Unlabelled: Epidemiologic evidence on the relationships between air pollution and the risks of primary cancers other than lung cancer remained largely lacking. We aimed to examine associations of 10-year exposures to fine particulate matter (PM) and nitrogen dioxide (NO) with risks of breast, prostate, colorectal, and endometrial cancers.

Methods: For each cancer, we constructed a separate cohort among the national Medicare beneficiaries during 2000 to 2016.

Application of geostationary satellite and high-resolution meteorology data in estimating hourly PM levels during the Camp Fire episode in California.

Wildland fire smoke contains large amounts of PM that can traverse tens to hundreds of kilometers, resulting in significant deterioration of air quality and excess mortality and morbidity in downwind regions. Estimating PM levels while considering the impact of wildfire smoke has been challenging due to the lack of ground monitoring coverage near the smoke plumes. We aim to estimate total PM concentration during the Camp Fire episode, the deadliest wildland fire in California history.

Tracking the impacts of climate change on human health via indicators: lessons from the Lancet Countdown.

Background: In the past decades, climate change has been impacting human lives and health via extreme weather and climate events and alterations in labour capacity, food security, and the prevalence and geographical distribution of infectious diseases across the globe. Climate change and health indicators (CCHIs) are workable tools designed to capture the complex set of interdependent interactions through which climate change is affecting human health. Since 2015, a novel sub-set of CCHIs, focusing on climate change impacts, exposures, and vulnerability indicators (CCIEVIs) has been developed, refined, and integrated by Working Group 1 of the "Lancet Countdown: Tracking Progress on Health and Climate Change", an international collaboration across disciplines that include climate, geography, epidemiology, occupation health, and economics.

Association between maximum temperature and PM with pregnancy outcomes in Lima, Peru.

Background: We have previously documented an inverse relationship between PM in Lima, Peru, and reproductive outcomes. Here, we investigate the effect of temperature on birth weight, birth weight-Z-score adjusted for gestational age, low birth weight, and preterm birth. We also explore interactions between PM and temperature.

The 2021 report of the Lancet Countdown on health and climate change: code red for a healthy future.

Unlabelled: The Countdown is an international collaboration that independently monitors the health consequences of a changing climate. Publishing updated, new, and improved indicators each year, the Countdown represents the consensus of leading researchers from 43 academic institutions and UN agencies. The 44 indicators of this report expose an unabated rise in the health impacts of climate change and the current health consequences of the delayed and inconsistent response of countries around the globe—providing a clear imperative for accelerated action that puts the health of people and planet above all else.

Effect modification by maximum temperature of the association between PM and short-term cardiorespiratory mortality and emergency room visits in Lima, Peru, 2010-2016.

Background: The health effects of fine particulate matter (PM) may be worse at higher temperatures.

Objective: To investigate temperature's effect on PM-mortality/morbidity associations in Lima, Peru.

Methods: Time-series regressions relating PM and temperature to mortality and emergency room (ER) visits during 2010-2016.

The association between asthma emergency department visits and satellite-derived PM in Lima, Peru.

Background: Asthma affects millions of people worldwide. Lima, Peru is one of the most polluted cities in the Americas but has insufficient ground PM (particulate matter that are 2.5 μm or less in diameter) measurements to conduct epidemiologic studies regarding air pollution.

PM exposure on daily cardio-respiratory mortality in Lima, Peru, from 2010 to 2016.

Background: There have been no studies of air pollution and mortality in Lima, Peru. We evaluate whether daily environmental PM exposure is associated to respiratory and cardiovascular mortality in Lima during 2010 to 2016.

Methods: We analyzed 86,970 deaths from respiratory and cardiovascular diseases in Lima from 2010 to 2016.

Correction to: Association of PM2.5 concentration with health center outpatient visits for respiratory diseases of children under 5 years old in Lima, Peru.

The original version of this article [1], published on 15 January 2020, contained incorrect name of the co- author. In this Correction the affected part of the article is shown.

Association of PM concentration with health center outpatient visits for respiratory diseases of children under 5 years old in Lima, Peru.

Background: Lima is one of the more polluted cities in Latin America. High levels of PM have been shown to increase health center outpatient visits of respiratory diseases.

Methods: Health center outpatient visits for children < 5 years for childhood respiratory disease (acute lower respiratory infections (ALRI), pneumonia and acute bronchiolitis/asthma) from 498 public clinics in Lima were available on a weekly basis from 2011 to 2015 from Peru's Ministry of Health (MINSA).

Increased Outdoor PM Concentration Is Associated with Moderate/Severe Anemia in Children Aged 6-59 Months in Lima, Peru.

Anemia affects 1.62 billion people worldwide. Although iron deficiency is the main cause of anemia, several other factors may explain its high prevalence.

Developing an Advanced PM Exposure Model in Lima, Peru.

It is well recognized that exposure to fine particulate matter (PM) affects health adversely, yet few studies from South America have documented such associations due to the sparsity of PM measurements. Lima's topography and aging vehicular fleet results in severe air pollution with limited amounts of monitors to effectively quantify PM levels for epidemiologic studies. We developed an advanced machine learning model to estimate daily PM concentrations at a 1 km spatial resolution in Lima, Peru from 2010 to 2016.
