BACKGROUND The inflammatory process involving Helicobacter pylori-associated gastritis is thought to lead to epithelial damage and contribute to the development of gastric cancer. Evidence exists from animal and in vitro studies suggesting that tetracyclines have both anti-inflammatory and tissue-protectant effects unrelated to their antimicrobial activity.(More)
Objectives:As there are no US population-based studies examining Lynch syndrome (LS) screening frequency by microsatellite instability (MSI) and immunohistochemistry (IHC), we seek to quantitate statewide rates in patients aged ≤50 years using data from a Centers for Disease Control and Prevention-funded Comparative Effectiveness Research (CER) project and(More)
The survival of unfed adult Hyalomma truncatum Koch held under different regimes of constant temperature (5, 17, 24, and 30 degrees C) and relative humidity (10, 50, and 80%) was monitored during > 1 yr. Longevity of this medically important African tick was shortest at the highest temperature and lowest relative humidity (100% dead at week 25). Conversely,(More)
A review of the literature reveals a very consistent association between gastric cancer risk and low intake of fruits and vegetables. This observation has been documented in many countries with different epidemiological techniques: interpopulation correlations, case-control studies and follow up of several cohorts. Low serum levels of beta-carotene and(More)
An international comparison of the ratio of mortality rates from gastric and duodenal ulcers (GU/DU) reveals a positive correlation with gastric carcinoma death rates. This correlation is driven by the rates of gastric ulcer and has decreased in recent decades. Genetic susceptibility factors appear to be involved in the pathogenesis of peptic ulcers:(More)
Conflicting reports of the effects of beta-carotene supplementation on serum alpha-tocopherol concentration led us to evaluated serum alpha-tocopherol in subjects with and without beta-carotene (30 mg/day) supplementation for up to 2 years duration in an ongoing chemoprevention trial. No adverse effect has been observed at any of the time periods examined.
Data from numerous studies show that lumpectomy (breast-conserving therapy) plus radiation therapy provides survival equivalent to that following mastectomy (either modified radical or radical mastectomy) for patients with ductal carcinoma in situ (DCIS). According to the data from the National Cancer Data Base and the Surveillance Epidemiology End Results(More)
Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer death among Louisiana women. The incidence data from Louisiana Tumor Registry were used to calculate breast cancer incidence rates, which were compared with the combined rates from the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER)(More)
OBJECTIVES In response to a previous finding of increased mortality from lymphohaematopoietic (LH) malignancies, this study examines incidence of LH malignancy in a petrochemical industry cohort. Emphasis is on chronic lymphocytic leukaemia (CLL) and on comparisons by period of first employment. METHOD The study cohort consists of 8942 employees who were(More)
