In 1967 three epidemiology department chairs, Drs. Abraham Lilienfeld (the Johns Hopkins University), Milton Terris (New York Medical College) and Brian MacMahon (Harvard University), proposed a new society. Their goals were to create a venue for their graduate students to present their research findings and exchange ideas with senior researchers and to establish a meeting at which epidemiologists studying chronic diseases, infectious diseases and mental health could come together. The first meeting of the Society for Epidemiological Research took place in May 1968 in Washington DC. ...

Our research is aimed at increasing knowledge about the etiology of major chronic diseases, mainly a broad range of cardiovascular diseases including cardiometabolic disorders, but also cancer, fractures, lung diseases, neurological diseases and gastrointestinal disorders. We also conduct research on exposures in relation to birth outcomes.

From a methodologic standpoint, the scholarly study was perfectly conducted, and the chance factor appealing, hemoglobin A1C, is available widely, while not measured in nondiabetic CKD sufferers consistently. Therefore, this research offers an exceptional possibility to review the interpretation of an applicant novel risk element in sufferers with CKD as well as the intellectual procedure that people must make use of to answer fully the question posed by our name. In traditional epidemiology, we evaluate organizations between characteristics appealing (predictors) and disease end factors (final results) to raised understand the condition procedure. Characteristics that may be associated with disease final results in epidemiologic research are known as risk elements; any suggested risk factor is certainly scrutinized by many follow-up questions. We will use the following four questions to evaluate the clinical effect of the paper by Trivin (1) and as a road map for where the literature on ...

BACKGROUND: Severity of viral respiratory illnesses can be increased with bacterial coinfection and can vary by sex, but influence of coinfection and sex on human endemic coronavirus (CoV) species, which generally cause mild to moderate respiratory illness, is unknown. We evaluated CoV and pneumococcal co-detection by sex in childhood pneumonia. METHODS: In the 2011-2014 Pneumonia Etiology Research for Child Health study, nasopharyngeal and oropharyngeal (NP/OP) swabs and other samples were collected from 3981 children ,5 years hospitalized with severe or very severe pneumonia in 7 countries. Severity by NP/OP detection status of CoV (NL63, 229E, OC43 or HKU1) and high-density (≥6.9 log10 copies/mL) pneumococcus (HDSpn) by real-time polymerase chain reaction was assessed by sex using logistic regression adjusted for age and site. RESULTS: There were 43 (1.1%) CoV+/HDSpn+, 247 CoV+/HDSpn-, 449 CoV-/HDSpn+ and 3149 CoV-/HDSpn- cases with no significant difference in co-detection frequency by sex ...

This book provides a practical guide to the understanding, interpretation, and application of the principles of nutritional epidemiology, set in the context of public health nutrition. Relating dietary and nutritional exposures to health outcomes requires a rigorous approach to measurement of both the key exposure and outcome variables of interest and also the associated measurement errors. Moreover, the analysis of such data requires appropriate statistical approaches that take into account sampling, measurement techniques, and the role of confounders in the context of specific study designs. The first part of the book brings a practical focus to the scientific concepts underlying study design with emphasis on design, planning, and evaluation of nutritional epidemiological studies; issues of sampling, sample size and power; and an understanding of the impact of measurement error, with practical remedies. The second part deals with the problems of measurement and interpretation of a variety of variables

BACKGROUND: Few data exist describing pertussis epidemiology among infants and children in low- and middle-income countries to guide preventive strategies. METHODS: Children 1-59 months of age hospitalized with World Health Organization-defined severe or very severe pneumonia in 7 African and Asian countries and similarly aged community controls were enrolled in the Pneumonia Etiology Research for Child Health study. They underwent a standardized clinical evaluation and provided nasopharyngeal and oropharyngeal swabs and induced sputum (cases only) for Bordetella pertussis polymerase chain reaction. Risk factors and pertussis-associated clinical findings were identified. RESULTS: Bordetella pertussis was detected in 53 of 4200 (1.3%) cases and 11 of 5196 (0.2%) controls. In the age stratum 1-5 months, 40 (2.3% of 1721) cases were positive, all from African sites, as were 8 (0.5% of 1617) controls. Pertussis-positive African cases 1-5 months old, compared to controls, were more often human

This course will focus on epidemiologic methods - primarily methods used in observational studies, cohort studies, case-control studies and randomized controlled trials. With respect to cohort studies, topics covered include cohort identification, ascertainment of exposure status, follow-up of cohort members, measuring outcomes, sources of bias and interpretational issues. Case-control topics include issues around defining cases and controls, control of confounding, and sources of bias/systematic error. Topics around randomized trials include randomization procedures, defining and assembling treatment/intervention arms, selecting study subjects and approaches to data collection. Other topics covered in this course include surveillance and ecologic studies. Pros and cons of all study designs will be discussed, in part through readings of published papers. Fundamentals of data analysis will also be addressed, but a detailed discussion is reserved for Epidemiology Research II.

Background.: Detection of pneumococcus by lytA polymerase chain reaction (PCR) in blood had poor diagnostic accuracy for diagnosing pneumococcal pneumonia in children in 9 African and Asian sites. We assessed the value of blood lytA quantification in diagnosing pneumococcal pneumonia. Methods.: The Pneumonia Etiology Research for Child Health (PERCH) case-control study tested whole blood by PCR for pneumococcus in children aged 1-59 months hospitalized with signs of pneumonia and in age-frequency matched community controls. The distribution of load among PCR-positive participants was compared between microbiologically confirmed pneumococcal pneumonia (MCPP) cases, cases confirmed for nonpneumococcal pathogens, nonconfirmed cases, and controls. Receiver operating characteristic analyses determined the optimal threshold that distinguished MCPP cases from controls. Results.: Load was available for 290 of 291 cases with pneumococcal PCR detected in blood and 273 of 273 controls. Load was higher in MCPP

Abstract: The analysis of causal effects when the outcome of interest is possibly truncated by death has a long history in statistics and causal inference. The survivor average causal effect is commonly identified with more assumptions than those guaranteed by the design of a randomized clinical trial. We demonstrate that individual level causal effects in the `always survivor principal stratum can be identified and quantified with no stronger identification assumptions than randomization. We illustrate the practical utility of our methods using data from a clinical trial on patients with prostate cancer. Our methodology is the first and, as of yet, only proposed methodology that enables detecting and quantifying causal effects in the presence of truncation by death and informative censoring using only the assumptions that are guaranteed by design of the randomized clinical trial.. *All talks will be held virtually through Zoom.

Epidemiologists are now embarking on the evaluation of the hypothesis that exposure to radio frequency energy from low-power wireless communication devices, such as portable cellular telephones, causes brain cancer and other adverse health outcomes. Even in the laboratory, exposures from radio frequency sources are difficult to quantify; their measurement in large populations for epidemiologic study is challenging. In this paper, we outline the nature and magnitude of these exposures and discuss the prospects for obtaining useful measures of exposure for epidemiologic research

Nutritional epidemiology uses epidemiological methods to examine associations between diet and disease. In the research group, we investigate whether dietary composition influtences the risk of developing cardiovascular disease, obesity, type 2 diabetes and cancer. We use large population studies, mainly the Malmö Diet and Cancer cohort, which was established in the 90s and consists of 28.098 individuals. Malmö Diet and Cancer have great opportunities to clarify nutrition relationships, as dietary data have high relative validity. Clear information about dietary influence is of great significance for public health because eating habits, in contrast to many other factors, can change during the life cycle. ...

Contents: There are two reasons for a statistical analysis. One is prediction of future data based on what one has learned from past data and accounting for uncertainty. Prediction need not be concerned with understanding cause-effect relationships, but understanding causality is central to our understanding of data and how we use that knowledge. For instance, standard statistical techniques allow to predict the survival probability of a current smoker, typically predicting earlier death compared to non-smokers. But there is no standard statistical technique that analyses the causal effect of smoking on mortality. The difficulty is that smoking is not assigned in a randomized experiment, and there are more differences between smokers and non-smokers than just smoking status. In fact, defining a causal effect is not even part of the usual statistical and mathematical formalism. In the last 30 years or so, there has been a statistical revolution of developing causal inference, motivated by ...

When assessing an environmental issue, it may be useful and appropriate to evaluate its links with human deaths and illnesses. Although this is difficult, and requires extensive professional analysis, you can begin to spot trends that raise questions worth asking by evaluating patterns of deaths and illness. Or you can use the patterns to confirm or challenge scientific research.. The data for doing this are increasingly available online to reporters and the general public. One of the latest developments is a recent upgrade of the US Centers for Disease Control and Preventions WONDER data for underlying causes of death. WONDER stands for Wide-ranging Online Data for Epidemiologic Research.. CDC has added a fifth year to the latest inventory (1999-2003), which helps smooth out the inevitable gyrations in number of deaths in any one location. Thats particularly important for cities or counties with lower populations, since just a few deaths can dramatically change the death rate.. In addition, ...

LUNET, Nuno. Epidemiological studies are like cherries, one draws another. Gac Sanit [online]. 2009, vol.23, n.5, pp.479-482. ISSN 0213-9111.. The proverb Words are like cherries, meaning that when you start talking subjects pop up and you end up with long conversations, just like cherries coming out of the plate in chains when you pick one, may also be applied to epidemiological research. A sequence of epidemiological studies, each being drawn from the previous, is presented as an example of how each investigation may raise new questions to be addressed in following studies. This description stresses the need for appropriate planning and the usefulness of pilot testing to depict inadequacies that can hardly be anticipated without field work. I intend to illustrate how epidemiological research can provide a deep approach to research questions, as long as findings are properly interpreted and suboptimal methodological options are taken into account in future investigations..

In an observational study, the researcher identifies a condition or outcome of interest and then measures factors that may be related to that outcome. Although observational studies cannot lead to strong causal inferences, they may nonetheless suggest certain causal hypotheses. To infer causation in observational studies, investigators attempt to establish a sequence of events if event A generally precedes event B in time, then it is possible that A may be responsible for causing B. Such studies may be either (the investigator tries to reconstruct what happened in the past) or prospective (the investigator identifies a group of individuals and
