Selected AbstractsUniversity faculty perceptions of the health risks related to cigarettes and smokeless tobaccoDRUG AND ALCOHOL REVIEW, Issue 2 2010NICHOLAS PEIPER Abstract Introduction and Aims. It is now widely understood by tobacco research and policy experts that smokeless tobacco (ST) use confers significantly less risk than smoking, but no studies have assessed tobacco risk perceptions in highly educated populations. The purpose of this study was to explore the perception of risks related to smoking and ST use among full-time faculty on two campuses at the University of Louisville. Design and Methods. In October 2007, a survey that quantified risk perceptions of cigarette smoking and ST use with respect to four health domains (general health, heart attack/stroke, all cancer, oral cancer) was sent to 1610 full-time faculty at the Belknap and the Health Sciences Center (HSC) campuses of the University of Louisville, and 597 (37%) returned a completed survey. Results. Overall, cigarettes were considered as high risk for all health domains by large majorities (75,97%). Except for heart attack/stroke, ST was also considered as high risk by the majority of faculty (69,87%), and at least half perceived cigarettes and ST to be equally harmful across all domains. HSC faculty had somewhat more accurate risk perceptions than Belknap faculty for ST, but both groups overestimated the risks, especially for oral cancer. Discussion and Conclusions. This study found that the risks of ST use are overestimated and conflated to that of cigarettes among highly educated professionals, demonstrating the need for better education about the risks of tobacco use and for communication of accurate information by health organisations and agencies.[Peiper N, Stone R, Van Zyl R & Rodu B.

Drug Alcohol Rev 2010] [source] Co-twin control and cohort analyses of body mass index and height in relation to breast, prostate, ovarian, corpus uteri, colon and rectal cancer among Swedish and Finnish twinsINTERNATIONAL JOURNAL OF CANCER, Issue 4 2007Ellen Lundqvist Abstract Associations between anthropometric measures and cancer have been studied previously, but relatively few studies have had the opportunity to control for genetic and early shared environmental factors. In this study, we analyzed 2 twin cohorts from Sweden born 1886,1925 (n = 21,870) and 1926,1958 (n = 30,279) and 1 from Finland born 1880,1958 (n = 25,882) including in total 78,031 twins, and studied the association between BMI and height and risk of prostate, breast, ovarian, corpus uteri, colon and rectal cancer. The cohorts were both analyzed through a co-twin control method and as traditional cohorts. In co-twin control analyses, older obese (BMI , 30 kg/m2) subjects (median age 56 years at baseline) were at higher risk of cancer of the corpus uteri (OR = 3.0; 95% CI 0.9,10.6), colon (OR = 1.9; 95% CI 0.8,4.5) and breast (OR = 2.5; 95% CI 1.3,4.2). For younger obese women (median age 30 years at baseline), an inverse tendency was observed for breast cancer (OR = 0.6; 95% CI 0.3,1.5, p for trend = 0.05). The tallest women had an increased risk of breast (OR = 1.8; 95% CI 1.3,2.7) and ovarian cancer (OR = 1.7; 95% CI 0.8,3.5). No consistent associations were found for prostate cancer either for BMI or height. There are some suggestions in our study that uncontrolled genetic or early shared environmental factors may affect risk estimates in studies of anthropometric measures and cancer risk, but do not explain observations of increased cancer risks related to BMI or height. © 2007 Wiley-Liss, Inc. [source] Demographic and risk factors in patients with head and neck tumorsJOURNAL OF MEDICAL VIROLOGY, Issue 5 2009Ruth Tachezy Abstract The association between human papillomavirus (HPV) infection and the development of head and neck cancer has been documented recently. In this study on 86 head and neck cancer patients and 124 controls, data regarding demographics, behavioral risk factors, and risks related to HPV exposure were collected. HPV detection was carried out using polymerase chain reaction in the tumors and in oral exfoliated cells, and HPV typing by a reverse line blot assay specific for 37 HPV types. Sera were tested by an enzyme-linked immunosorbent assay specific for HPV proteins. Head and neck cancer cases report significantly more oral-anal contact (P,=,0.02) and tobacco and alcohol use than controls (P,=,0.001; P,=,0.02, respectively). High-risk HPV DNA was detected in 43% of oral washings of cases and 4% of controls (P,<,0.0001). The association between the presence of high-risk HPV DNA in oral exfoliated cells and in tumor tissues was statistically significant (adjusted P,<,0.0001). The prevalence of HPV-specific antibodies was significantly higher in cases than in controls (adjusted P,<,0.0001). These results provide epidemiological and immunological evidence for HR HPV as a strong risk factor (OR,=,44.3, P,<,0.0001) for head and neck cancer, even after controlling for age, tobacco and alcohol use. The detection of high-risk HPV DNA in oral exfoliated cells and HPV-specific antibodies in serum can be considered as clinically relevant surrogate markers for the presence of a HPV-associated head and neck cancer, with a high sensitivity (83%) and specificity (88%).

[source] Interactions of Valeriana officinalis L. and Passiflora incarnata L. in a patient treated with lorazepamPHYTOTHERAPY RESEARCH, Issue 12 2009Marķa Consuelo Carrasco Abstract There is an increasing interest in the health risks related to the use of herbal remedies. Although most consumers think that phytomedicines are safe and without side effects, interactions between complementary alternative and conventional medicines are being described. The aim of this clinical case report is to highlight the importance of the safe use of herbal remedies by providing a clinical interaction study between pharmaceutical medicines and herbal medicinal products. The case of a patient self-medicated with Valeriana officinalis L. and Passiflora incarnata L. while he was on lorazepam treatment is described. Handshaking, dizziness, throbbing and muscular fatigue were reported within the 32 h before clinical diagnosis. The analysis of family medical history ruled out essential tremor, Parkinson's disease, Wilson's disease and other symptom-related pathologies. His medical history revealed a generalized anxiety disorder and medicinal plant consumption but no neurological disorder. Appropriate physical examination was carried out. An additive or synergistic effect is suspected to have produced these symptoms. The active principles of Valerian and passionflower might increase the inhibitory activity of benzodiazepines binding to the GABA receptors, causing severe secondary effects. Due to the increase in herbal product self-medication, the use of herbal remedies should be registered while taking the personal clinical history. Multidisciplinary teams should be created to raise studies on medicinal plants with impact on medical praxis. Copyright © 2009 John Wiley & Sons, Ltd. [source] | ||||||||||
