MedicalResearch.com Interview with: Tao Liu Ph.D Guangdong Provincial Institute of Public Health Guangdong Provincial Center for Disease Control and Prevention MedicalResearch.com: What is the background for this study? What are the main findings? Response: Hypertension is the most important cause of disability and the leading risk factor for death globally and causes approximately 16.5% of all deaths. Since the 1990s, many epidemiological studies have investigated the associations between air pollution exposure and hypertension, the two most common public health concerns. However, their results remain controversial. Some studies found an association between them, while other studies sowed either no association or an association only for selected pollutants. In order to quantitatively synthesize and interpret these inconsistent and controversial results, here we used a new analysis method (Meta-analysis) to combine results from different previous studies to estimate the overall effect of every air pollutant on hypertension. This is the first study to simultaneously estimate the effects of short-term and long-term exposure to air pollutants on hypertension by meta-analysis. These results could provide more explicit information for policy decisions and clinical use. (more…)

MedicalResearch.com Interview with: Maayan Yitshak Sade MPH Chief Scientific Officer Clinical Research Center, Soroka University Medical Center, Israel and   Victor Novack, MD, PhD Soroka University Medical Center and Ben-Gurion University in Beer Sheva, Israel   MedicalResearch.com: What is the background for this study? Response: Numerous studies found association between exposure the air pollution and increased risk of cardiovascular and respiratory diseases. In recent years links were found between air pollution and diabetes as well. The scientific evidence supports a causal association between air pollution and oxidative stress, possibly involving impaired metabolism of glucose and lipids. In a recent study performed by our group, we observed a significantly increased risk for ischemic stroke among young adults, associated with air pollution exposure. Following these findings, and as a part of the possible theory linking the association air pollution exposure and cardiovascular diseases, we sought to investigate if this association might be mediated through the well-established cardiovascular risk factors such as abnormal lipid and glucose metabolism.

MedicalResearch.com Interview with: Kathryn Reid PhD Research associate Professor of Neurology Northwestern University Feinberg School of Medicine.  MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Reid: There is increasing evidence that light and dark exposure patterns over time impact health outcomes such as body weight and food intake. This study found that bright light exposure increased insulin resistance compared to dim light exposure in both the morning and the evening. In the evening, bright light also caused higher peak glucose (blood sugar) levels. (more…)

Medical Research Interview with: Eva Morales, MD, PhD, MPH Centre for Research in Environmental Epidemiology (CREAL) Barcelona Biomedical Research Park Barcelona, Spain Medical Research: What are the main findings of the study? Dr. Morales: We aimed to assess the consequences of exposure to outdoor air pollution during specific trimesters of pregnancy and postnatal lifetime periods on lung function in preschool children. We conducted a longitudinal study by using data from 620 mother-child pairs participating in the INfancia y Medio Ambiente (INMA) Project – a population-based cohort study set up in several geographic areas in Spain. We found that exposure to outdoor air pollution during the second trimester of pregnancy in particular raises the risk of harm to a child’s lung function at preschool age. (more…)

Elaine Fuertes Institute of Epidemiology I, Helmholtz Zentrum München, German Research Centre for Environmental Health Neuherberg, Germany and School of Population and Public Health University of British Columbia, Vancouver, British Columbia, CanadaMedicalResearch.com Interview with: Elaine Fuertes Institute of Epidemiology I, Helmholtz Zentrum München, German Research Centre for Environmental Health Neuherberg, Germany and School of Population and Public Health University of British Columbia, Vancouver, British Columbia, Canada MedicalResearch: What are the main findings of the study? Answer: The main finding of our study was that despite the use of identical study designs and statistical methods, the level of greenness (measured using the Normalized Difference Vegetation Index) around a child's home address was differentially associated with the development of allergic health outcomes among children living in two areas in Germany. In our urban study centre, which includes the city of Munich, we found that higher greenness levels around a child's home increased their risk of developing allergic rhinitis and experiencing eyes and nose symptoms. In contrast, greenness around the home appeared to be protective for allergic rhinitis, nose and eye symptoms and sensitization to inhalant allergens in the second more rural study centre investigated. These observations emphasize that the effects of greenness around the home on respiratory health is complex and multifaceted, and are based on 5,803 German children followed from birth to 10 years as part of the GINIplus and LISAplus birth cohorts.

Kesava Reddy, PhD, MHA University Cancer and Diagnostic Centers, Houston, TexMedicalResearch.com  interview with: Kesava Reddy, PhD, MHA University Cancer and Diagnostic Centers, Houston, Tex     MedicalResearch.com: What are the main findings of the study? Dr. Reddy: Crude oil spills affect the human health through their exposure to the inherent hazardous chemicals such as para-phenols and volatile benzene. Evidence show that oil spill exposure is associated with multiple adverse health effects and increased cancer risk. In this study, we assessed the adverse health effects of the Gulf oil spill exposure in subjects participating in the clean-up operation along the coast of Louisiana. The findings were compared with those not exposed to the oil spill. We found that platelet counts were notably decreased in the oil spill exposed group. In addition, creatinine and blood urea nitrogen levels were substantially lower in the exposed group, while hemoglobin and hematocrit levels were increased compared to the unexposed subjects. Furthermore, considered indicators of hepatic damage, the serum alkaline phosphatase (ALP), aspartate amino transferase (AST), alanine amino transferase (ALT), levels in the exposed subjects were also elevated. Participants  in the oil spill cleanup activity also reported somatic symptoms, with headache reported most frequently, followed by shortness of breath, skin rash, cough, dizzy spells, fatigue, painful joints, night sweats, and chest pain.

MedicalResearch.com Interview with: Dr Anoop Shah MBChB Cardiology Research fellow Centre of Cardiovascular sciences Chancellors Building University Of Edinburgh Little France Edinburgh MedicalResearch.com: What are the main findings of the study? Answer: Many studies have shown the effect of air pollution on cardiac mortality and myocardial infarction. Less studies have shown a similar effect on patients with heart failure. We therefore systemically reviewed and pooled data across 12 countries involving over 4 million patients with heart failure. We showed that air pollution has a close temporal association with either being hospitalized or dying from heart failure. Most of the effects of air pollution on patients with heart failure were acute. Most of the data that we analyzed came from developed countries across Europe and the USA. There was a  significant paucity of data from rapidly urbanizing nations such as India and China. (more…)

Ole Raaschou-Nielsen, MSc, PhD Head of Research Group for Work, Environment & Cancer Danish Cancer Society Research Center Strandboulevarden 49 2100 Copenhagen ØMedicalResearch.com Interview with: Ole Raaschou-Nielsen, MSc, PhD Head of Research Group for Work, Environment & Cancer Danish Cancer Society Research Center Strandboulevarden 49 2100 Copenhagen Ø MedicalResearch.com: What are the main findings of the study? Answer: The study shows that people who live at locations with higher levels of particles in the air are at higher risk for development of lung cancer. It seems that there is no threshold for air pollution with particles below which there is no risk; the results show that it is more like “the more air pollution the worse and the less pollution the better”. The strongest association was seen for adenocarcinoma of the lung. (more…)
