Long-term exposure to air pollution and risk of dementia among older individuals of a Danish nationwide administrative cohort.

Background: Increasing evidence associates air pollution with dementia, but some pollutants and susceptible groups are understudied.

Methods: We followed all Danish residents aged ≥60 years as of 1-1-2000, without prior dementia, until 12-31-2018 for dementia incidence identified via hospital contact or prescription. We assessed annual mean levels of fine particulate matter (PM), nitrogen dioxide (NO), and black carbon (BC) in 2010 utilizing European-wide hybrid land-use regression models, at baseline (2000) residential addresses.

Short-term exposure to ultrafine particles and respiratory infection hospital admissions in children in Copenhagen, Denmark.

Introduction: Short-term exposure to ultrafine particles (UFP; <100 nm) may trigger respiratory hospitalizations, potentially even more so among children than adults, but available evidence is limited. We examined the association between short-term UFP exposure and respiratory infection hospital admissions in children in Copenhagen, Denmark.

Methods: Daily concentrations of UFP were monitored at an urban background station during 2002-2018.

Exposure to ultrafine particles while bicycling in a residential area near Copenhagen International Airport, Denmark: A repeated measures study.

Airports are major sources of ultrafine particles (UFP), raising health concerns among people living in immediate proximity. However, little is known about UFP concentrations in residential areas around airports. In this study, we mapped UFP exposure concentrations in a residential area nearby Copenhagen International Airport (CPH).

Short-term exposure to ultrafine particles and asthma hospital admissions in children in Copenhagen, Denmark.

Background: Ultrafine particles (UFP; <0.1 µm in diameter) are not regulated or commonly monitored but may be harmful to human health, particularly for children. In this study, we aimed to examine the association between short-term exposure to UFP and asthma hospital admissions in children.

Long-Term Exposure to Ambient Air Pollution and Lower Respiratory Tract Infection in Adults: Danish Nationwide Evidence.

Long-term exposure to air pollution has been linked with acute lower respiratory infections (ALRIs) in children, but the evidence in adults is still mixed and sparse. We aimed to examine the association between long-term exposure to air pollution and incident ALRIs in adults. We followed all Danish residents aged ≥30 years ( = 3,083,227) for the first-ever hospital contact (inpatient, outpatient, or emergency) for ALRIs (and pneumonia or influenza separately) from 2000 to 2018.

Long-term exposure to green and blue space and incidence of cardiovascular disease: A Danish Nurse Cohort study.

Background: Few cohort studies have examined the associations of natural surroundings (green and blue space) with cardiovascular disease (CVD) and show mixed findings. We aimed to investigate the associations between long-term exposure to green and blue space and incidence of CVD in the Danish Nurse Cohort.

Methods: We followed 19,070 female nurses living in Denmark from 1993/1999 to 2018.

Long-term exposure to road traffic noise and acute lower respiratory infections in the Danish Nurse Cohort.

Background: Long-term exposure to road traffic noise is associated with cardiovascular disease, but the evidence on respiratory diseases is just emerging. We aimed to examine the association between long-term exposure to road traffic noise and the incidence of acute lower respiratory infections (ALRIs) in adults.

Methods: We followed 23,141 female nurses (age ≥ 44 years) from the Danish Nurse Cohort from baseline (1993 or 1999) to their first hospital contact (inpatient, outpatient, or emergency room) for ALRI, death, emigration or the end of 2015.

Long-term exposure to air pollution and road traffic noise and incidence of dementia in the Danish Nurse Cohort.

Introduction: We examined the association of long-term exposure to air pollution and road traffic noise with dementia incidence in the Danish Nurse Cohort.

Methods: Female nurses were followed for dementia incidence (hospital contact or medication prescription) from 1993/1999 to 2020. Air pollution and road traffic noise levels were estimated at nurses' residences, and their associations with dementia were examined using Cox regression models.

Long-Term Exposure to Air Pollution and Risk of Acute Lower Respiratory Infections in the Danish Nurse Cohort.

Air pollution is a major risk factor for chronic cardiorespiratory diseases, affecting the immune and respiratory systems' functionality, but epidemiological evidence in respiratory infections remains sparse. We aimed to assess the association of long-term exposure to ambient air pollution with the risk of developing new and recurrent acute lower respiratory infections (ALRIs), characterized by persistently severe symptoms necessitating hospital contact, and identify the potential susceptible populations by socioeconomic status, smoking, physical activity status, overweight, and comorbidity with chronic lung disease. We followed 23,912 female nurses from the Danish Nurse Cohort (age >44 yr) from baseline (1993 or 1999) until 2018 for incident and recurrent ALRIs defined by hospital contact (inpatient, outpatient, and emergency room) data from the National Patient Register.

Lifetime exposure to air pollution and academic achievement: A nationwide cohort study in Denmark.

Recent research suggests a link between air pollution and cognitive development in children, and studies on air pollution and academic achievement are emerging. We conducted a nationwide cohort study in Denmark to explore the associations between lifetime exposure to air pollution and academic performance in 9th grade. The study encompassed 785,312 children born in Denmark between 1989 and 2005, all of whom completed 9th-grade exit examinations.

Short-term exposure to ultrafine particles and mortality and hospital admissions due to respiratory and cardiovascular diseases in Copenhagen, Denmark.

Ultrafine particles (UFP; particulate matter <0.1 μm in diameter) may be more harmful to human health than larger particles, but epidemiological evidence on their health effects is still limited. In this study, we examined the association between short-term exposure to UFP and mortality and hospital admissions in Copenhagen, Denmark.

Retrospective assessment of pregnancy exposure to particulate matter from desert dust on a Caribbean island: could satellite-based aerosol optical thickness be used as an alternative to ground PM concentration?

Desert dust transported from the Saharan-Sahel region to the Caribbean Sea is responsible for peak exposures of particulate matter (PM). This study explored the potential added value of satellite aerosol optical thickness (AOT) measurements, compared to the PM concentration at ground level, to retrospectively assess exposure during pregnancy. MAIAC MODIS AOT retrievals in blue band (AOT) were extracted for the French Guadeloupe archipelago.

Proficiency of Medical Students at Obtaining Pressure Measurement Readings Using Automated Ankle and Toe Measuring Devices for Diagnosis of Lower Extremity Peripheral Artery Disease.

Background: Pressure measurement is a key component in the diagnosis of lower extremity peripheral artery disease (PAD) but is technically challenging and time-consuming for nonvascular specialists, thus hindering its wider implementation. The aim of this study was to assess the proficiency of students at obtaining satisfactory ankle or toe pressure readings for PAD diagnosis using 2 automated devices.

Methods: Medical students followed a training session after which they performed ankle and toe pressure measurements to calculate the ankle-brachial index (ABI) using the MESI ABPI MD® device, and the toe-brachial index (TBI) using the SYSTOE® device.

Assessment of endothelial function and myocardial flow reserve using (15)O-water PET without attenuation correction.

Purpose: Myocardial blood flow (MBF) measurement using positron emission tomography (PET) from the washout rate of (15)O-water is theoretically independent of tissue attenuation. The aim of this study was to evaluate the impact of not using attenuation correction in the assessment of coronary endothelial function and myocardial flow reserve (MFR) using (15)O-water PET.

Methods: We retrospectively processed 70 consecutive (15)O-water PET examinations obtained at rest and during cold pressor testing (CPT) in patients with dilated cardiomyopathy (n = 58), or at rest and during adenosine infusion in heart transplant recipients (n = 12).
