 BMA - BMA cohort study ninth report
Cohort doctors were asked to rate satisfaction with their current work-life balance on a scale from 1(least satisfied) to 10 (most satisfied).
Furthermore, cohort doctors who chose a career in general practice are more likely to also be working less than full-time at some point, compared with doctors who chose a career in hospital medicine.
A fifth of cohort doctors worked in some form of research post during the past year.

 ATSDR - El Paso Multiple Sclerosis Cluster Investigation
Within the scope of this study, we were not able to access one potentially very important source of information for the E.B. Jones cohort which also may have facilitated tracing, worker records from the smelter which employed the people who lived in Smeltertown.
El Paso and ASARCO were the focus of a landmark study examining blood lead levels in the communities in the vicinity of the smelter in 1972.
The delay from the time the initial cluster was reported to TDH to the time the study was funded and initiated may have negatively affected both our tracing activities and cohort response rates.

 VACS: Veterans Aging Cohort Study
The Veterans Aging Cohort Study (VACS) is a prospective, observational cohort study of HIV- positive and an age/race/site matched control group of HIV- negative veterans in care in the United States.
The first, assembled from administrative data alone, is a “virtual cohort” of >40,000 HIV- positive veterans and a similar number of age/race/site matched HIV- negative controls, used to understand the overall impact of HIV and comorbid conditions on survival and health-care utilization.
This in-depth cohort allows us to “get behind” gross associations with outcome, to better understand the likely complex and overlapping etiologies resulting in differences outcome and patient utilization.

 [No title]
A Cohort Study is a study in which patients who presently have a certain condition and/or receive a particular treatment are followed over time and compared with another group who are not affected by the condition under investigation.
The main problem with cohort studies, however, is that they can end up taking a very long time, since the researchers have to wait for the conditions of interest to develop.
Physicians are, of course, anxious to have meaningful results as soon as possible, but another disadvantage with long studies is that things tend to change over the course of the study.

 NIH Guide: COHORT STUDIES IN CANCER EPIDEMIOLOGY
Also, because study factor information must be observed at the outset of the study, a cohort study design limits opportunities for generating new etiologic hypotheses requiring information on other, unanticipated exposures.
However, these types of population-based cohort studies are usually substantially more time-consuming and expensive than most cross-sectional and case-control approaches, and are usually less suitable for study of more uncommon outcomes unless very large numbers of subjects are followed.
Applications pursuant to this PA are limited to population-based epidemiologic and survivorship cohort studies of human cancers.

 An Expanded Cohort Study of Cancer Among Benzene-exposed Workers in China
Based on analysis of the incidence in the largest cohort, it was confirmed that benzene is a leukemogen, especially for myelogenous leukemia in humans, and benzene is possibly also associated with excess risk of non-Hodgkin's lymphoma and lung cancer among humans.
The present study was initiated as a collaboration between the Institute of Occupational Medicine, China, and the U.S. National Cancer Institute (NCI), based on an earlier retrospective cohort study carried out by Chinese investigators among 28,480 benzene-exposed and 28,257 unexposed workers followed up from 1972 to 1981 in China (5).
The major reasons for expanding upon the original cohort study were to include substantially more subjects, additional person-years of follow-up, and more leukemia cases, for analyzing in detail the relationship of benzene with subtype of leukemia and other hematolymphoproliferative malignancies.

 Cohort study - Wikipedia, the free encyclopedia
A cohort study is a form of longitudinal study used in medicine and social science.
The study groups, so defined, are observed over a period of time to determine the frequency of disease among them.
Shorter term studies are commonly used in medical research as a form of clinical trial, or means to test a particular hypothesis of clinical importance.

 UBC Sawmill Cohort Study
Central to this is the large cohort study of approximately 26,000 BC Sawmill workers which examined a number of health effects associated with chlorophenate and dioxin exposure.
The original purpose of the study was to examine the effects of chorophenate fungicides, which are no longer used in B.C. sawmills.
This approach allows both the efficient use of occupational cohorts as well as providing the opportunity for investigators to develop a more comprehensive perspective on the determinants of the health status of workers and their families.

 Pooling Project of Prospective Studies of Diet and Cancer at Harvard School of Public Health
Each study is a published cohort study which 1) used a comprehensive dietary assessment method to measure usual diet, 2) assessed the validity of their dietary assessment instrument or a closely related instrument, and 3) included a minimum number of cases of the specific cancer being examined.
The Netherlands Cohort Study on diet and cancer is an ongoing cohort study that was initiated in 1986.
This project is an example of a retrospectively planned meta-analysis of individual patient data as opposed to a prospectively planned meta-analysis of individual patient data or a meta-analysis of the published literature.

 A National Prospective Cohort Study of American Children
The initiation of a children's cohort study could be one of this generation's most important legacies.

 Drinking Water Arsenic in Utah: A Cohort Mortality Study
During this study, the investigators were able to gather a considerable number of arsenic concentrations from private wells, so that estimates of exposure to arsenic from drinking water for individuals may be possible in future studies.
This cohort was expanded in a second phase of data collection to include all individuals who lived for any length of time in the study communities.
Males in the mortality cohort had significantly less mortality due to all malignant cancers and cancer of the digestive organs and peritoneum, large intestine, and respiratory system than Utah white males.

Cohorts complement randomized clinical trials -- there are currently no on-going randomized clinical trials that directly address these needs.
One of the most frequent objections to carrying out randomized, controlled trials to answer questions about long-term effectiveness is that observational cohort studies could provide the answers faster, more cheaply and as a closer proxy to real-world clinical experience.
We do not have any large-scale randomized studies which can show clinically the benefit of early vs. later initiation of antiretroviral therapy.

One of the limitations of our study is that we cannot say for certain that no uncircumcised child included had a circumcision outside the hospital setting, since we had information only on hospital circumcisions.
Our study used a cohort based on population data (including almost 60 000 infants) to estimate subsequent UTI risk in relation to circumcision.

Sixty members of the cohort who were seronegative in 1984 were tested again in 1985, an average of 14 months (range 9-18) after their last specimens were collected; nine (15.0%) were found to have developed antibodies to HTLV-III/LAV.
