© 1998 - Founded in 1905 to combat TB, the ATS has grown to tackle asthma, COPD, lung cancer, sepsis, acute respiratory distress, and sleep apnea, among other diseases. Finally, avoid including variables in the causal pathway as potential confounders as they will mask risk factors that may be causal in a given disease state. Both the children's biological and adoptive parents were identified. The former, Titler notes, is research focused on rigorous testing of implementation strategies in “real world settings;” the aim of translational research is to identify which strategies are more effective in promoting uptake and use of evidence among diverse patient groups in various contexts. [CDATA[ Therefore, once an association has been identified in a univariate analysis, it is important to confirm its effects in a stratified or multivariable analysis to account for possible confounders or effect modification. In a more recent genetic study, Marshall reported the increased frequency of a polymorphism in the ACE gene in patients with ARDS, suggesting that a genetic variant can increase the likelihood of developing ARDS [7]. to download free article PDFs, For example, basic science investigators in our group developed a septic model to examine the effects of alcohol abuse in rats. Customize your JAMA Network experience by selecting one or more topics from the list below. Although the association of patient positioning and the development of ventilator-associated pneumonia were still evident in patients not receiving enteral nutrition, it is much greater in those who are (figure 8). As illustrated in figure 6, an exposure is identified that is believed to be associated with a specific outcome. The National Institutes of Health (NIH) has made translational research a priority, forming centers of translational research at its institutes and launching the Clinical and Translational Science Award (CTSA) program in 2006. It is important to realize that factors associated with disease development may not be associated with disease outcomes. Translational research is becoming an increasingly important factor in most medical specialties. Potential confounding variables can be identified by careful examination of the literature. Obviously, many more cases of lung cancer are present in the smoking individuals compared to the non-smokers. With large samples (databases), some factors such as race, gender, and age should be examined as potential confounding variables. In summary, heterogeneity in the incidence of ARDS due to chronic alcohol abuse was initially observed in a clinical sample of patients with ARDS. Assistance with some of the difficult tasks faced by translational investigators appears to be more forthcoming in recent years than in the past, as will be discussed in this monograph. billion budget for health-related research, and the United Kingdom has invested £450 million over 5 years to establish translational research centers.2, Woolf SH. Glutathione deficiency was proposed as a mechanism to account for these findings through its effects on surfactant secretion, apoptosis, and alveolar epithelial fluid transport, leading to increased susceptibility for ARDS. but it seems important to almost everyone. barriers in the translational research process. With 24 CTSA-funded academic centers already established, other universities are transforming themselves to compete for upcoming CTSA grants. The last half century has yielded many basic discoveries. document.write(new Date().getFullYear()) Similarly, anti-TNF antibodies may only be benefit septic patients who are TNF hypersecretors based on genetic polymorphisms, and might be harmful for those septic patients who are TNF hyposecretors. It is therefore more accurate to discuss the effects of body position on VAP in relation to the presence or absence of enteral feeding as it is an effect modifier on the relationship between body position and the development of VAP.

For example, if regular physical activity is being examined in relationship to cardiovascular disease, one might not include HDL levels in the multivariable analysis because the effect of exercise on HDL levels may be the mechanism by which physical activity limits the cardiovascular disease, thus masking the effects of a sedentary life style on cardiovascular disease. A fundamental objective of translational research is the development of a “personalised medicine” which enables therapy to be customised for a certain patient.

Moss and colleagues have reported that a prior history of alcohol abuse, an acquired risk factor, is associated with an increased incidence and severity of ARDS [8]. Epidemiological studies can also be analytical, where determinants of variability in a disease are sought. However, analyzing the entire cohort after first stratifying subjects into smokers and non-smokers, and then examining the effects of alcohol on the incidence of lung cancer in each of these two groups separately, one finds that the effects of alcohol abuse on the development of lung cancer go away (odds ratio for both analyses is 0.63, (figure 7b). The stronger an association, the more likely it is to be causal, and associations that are consistently reported in the literature are more likely to be causal. Heterogeneity may be a beneficial phenomenon for identifying specific subgroups of patients that merit further investigation in a particular disease state. When studying an exposure-disease relationship, it is imperative to determine if the association is causal in nature. The application of findings derived in basic science to the development of new understanding of disease mechanisms, diagnoses, and therapeutics in humans is known as translational research [ 1 ]. Performance of successful translational research is highly dependent on an investigator's environment, as evidenced by the examples cited in this monograph. In Nuckton's study [9], the size of the dead space ventilation, although associated with mortality, is unlikely to be a risk factor for the development of ARDS. By 2012, the NIH expects to fund 60 such centers with a budget of $500 The etiology of these racial and gender disparities is probably related to genetic factors, acquired factors, and components of the acute illness. Ultimately, discoveries made at the bench were examined prospectively in a cohort of patients where mechanisms operative in animals were determined to be applicable to human subjects. From there potential therapies need to be identified and developed, and then undergo the rigorous methodologies of phase I, II, and III trials. All Rights Reserved. This data is based on the assumption that a majority of clinical researchers will hold MD degrees, in contrast to PhDs who are more likely to engage in basic science research. Effect modification describes the variation in association between exposure and disease according to the magnitude of another factor. C all it what you will – a “golden spike,” a “missing link,” a “crossroads” – translational research is a critically important trend at NIH.. Translational research activities are intended to bring knowledge from the lab into practice, and ideally, allow practice to influence what occurs in the laboratory. Future studies are necessary to further explore these associations. The next step in examining a hypothesis is to determine how significant an association may be using Bradford-Hill criteria. Heterogeneity in patient populations is a key concept in identifying clinically relevant associations that warrant further investigation. The ICU population comprises a heterogeneous group of patients with syndromes (eg ARDS, sepsis) rather than diseases, leading to difficulties in the performance of clinical trials in the ICU. A classic example of genetic factors affecting outcome was illustrated by Sorensen and colleagues [6], who studied causes of premature death in children who were adopted at an early age.

Ideas for epidemiological studies in an attempt to identify important associations between demographic characteristics and clinically relevant outcomes often arise from observing ICU patients and reading the medical literature.
