Trends and Determinants of Up-to-date Status with Colorectal Cancer Screening in Tennessee, 2002-2008

BACKGROUND: Screening rates for colorectal cancer (CRC) are increasing nationwide including Tennessee (TN); however, their up-to-date status is unknown. The objective of this study is to determine the trends and characteristics of TN adults who are up-to-date status with CRC screening during 2002-2008. METHODS: We examined data from the TN Behavioral Risk Factor Surveillance System for 2002, 2004, 2006 and 2008 to estimate the proportion of respondents aged 50 years and above who were up-to-date status with CRC screening, defined as an annual home fecal occult blood test and/or sigmoidoscopy or colonoscopy in the past 5 years. We identified trends in up-to-status in all eligible respondents. Using multivariable logistic regression models, we delineated key characteristics of respondents who were up-to-date status. RESULTS: During 2002-2008, the proportion of respondents with up-to-date status for CRC screening increased from 49% in 2002- 55% in 2006 and then decreased to 46% in 2008. The screening rates were higher among adults aged 65-74 years, those with some college education, those with annual household income ≥$35,000 and those with health-care access. In 2008, the respondents who were not up-to-date status with CRC screening included those with no health-care coverage (adjusted odds ratio [OR] 0.46, 95% confidence interval [CI] 0.33-0.63), those aged 50-54 years (OR 0.62, 95% CI 0.46-0.82) and those with annual household income CONCLUSIONS: TN adults who are up-to-date status with CRC screening are increasing, but not across all socio-demographic subgroups. The results identified specific subgroups to be targeted by screening programs, along with continued efforts to educate public and providers about the importance of CRC screening

Processing of fine size minerals : Studies on some Indian uranium ores

Conventionally uranium ores are processed by direct chemical leaching techniques. However, the application of chemical leaching for lean tenor and high tonnage uranium- ores is being desisted due to obvious environmental concerns. It is in this context that the physical benefi-ciation methods for the pre-concentration of uranium ores, if feasible, are gaining importance. Adoption of physical beneficiation helps in containing uranium and daughter nuclides in a smaller mass of pre-concentrate, which can be further subjected to conventional chemical processing, leaving bulk of the ore safe for disposal. In the application of physical beneficiation techniques, particle size plays a significant role. Both the economic mineral of uranium - uraninite and pitchblend, are brittle and report in very fine sizes during comminution, an oper-ation meant for their liberation.It is well established fact that concentration of particles finer than 25um by conventional physical beneficiation methods is very difficult due to the low mass and high surface area. However with the advent of new fine particle concentrators and techniques the situation has shown tremendous impr-ovement. This paper highlights the studies carried out on the use of both physical (gravity and magnetic) and physico-chemical beneficiation methods for recovering fine size uranium values from some low grade uranium bearing ores of India

Epithelioid trophoblastic tumor: a case report of a rare trophoblastic neoplasm

Epithelioid Trophoblastic Tumor (ETT) is a rare neoplasm of the chorionic type intermediate trophoblastic cells. It is a neoplasm of reproductive age women and usually follows a gestational event. ETT can occur at both intra uterine and extra uterine sites and can be confused with other entities such as squamous cell carcinoma, placental site nodule, placental site trophoblastic tumor etc. Hence, proper diagnosis of this tumor is necessary to avoid unnecessary, excessive treatment as surgical treatment is considered sufficient for ETT. We present a case of ETT in a 36 year old female, who came with symptoms of pain abdomen, white discharge per vaginum and a cervical mass

Primary pulmonary synovial sarcoma: a rare case report

Primary lung sarcoma is an extremely rare tumor, accounting for less than 0.5% of all lung tumors. Histological subtypes are differentiated on the basis of immunohistochemical markers, such as vimentin, desmin, actin, CD99, and epithelial membrane antigen. A 50-year-old male presented with progressively increasing shortness of breath with cough for 2 months. On Contrast Enhanced Computed Tomography (CECT) of thorax a large heterogeneous mass with multiple areas of necrosis, occupying almost whole of left hemithorax was seen. CT-guided Fine Needle Aspiration Cytology (FNAC) revealed spindle cell neoplasm. Histopathological examination revealed a spindle cell sarcoma. On immunohistochemistry the tumor cells expressed both epithelial membrane antigen and vimentin. Hence, final impression from immunohistochemistry was primary monophasic synovial sarcoma of lung

Uncontrolled Hypertension Increases Risk of All-Cause and Cardiovascular Disease Mortality in Us Adults: The NHANES III Linked Mortality Study

Clinical trials had provided evidence for the benefit effect of antihypertensive treatments in preventing future cardiovascular disease (CVD) events; however, the association between hypertension, whether treated/untreated or controlled/uncontrolled and risk of mortality in US population has been poorly understood. A total of 13,947 US adults aged ≥18 years enrolled in the Third National Health and Nutrition Examination Survey (1988-1994) were used to conduct this study. Mortality outcome events included all-cause, CVD-specific, heart disease-specific and cerebrovascular disease-specific deaths, which were obtained from linked 2011 National Death Index (NDI) files. During a median follow-up of 19.1 years, there were 3,550 all-cause deaths, including 1,027 CVD deaths. Compared with normotensives, treated but uncontrolled hypertensive patients were at higher risk of all-cause (HR = 1.62, 95%CI = 1.35-1.95), CVD-specific (HR = 2.23, 95%CI = 1.66-2.99), heart disease-specific (HR = 2.19, 95%CI = 1.57-3.05) and cerebrovascular disease-specific (HR = 3.01, 95%CI = 1.91-4.73) mortality. Additionally, untreated hypertensive patients had increased risk of all-cause (HR = 1.40, 95%CI = 1.21-1.62), CVD-specific (HR = 1.77, 95%CI = 1.34-2.35), heart disease-specific (HR = 1.69, 95%CI = 1.23-2.32) and cerebrovascular disease-specific death (HR = 2.53, 95%CI = 1.52-4.23). No significant differences were identified between normotensives, and treated and controlled hypertensives (all p \u3e 0.05). Our study findings emphasize the benefit of secondary prevention in hypertensive patients and primary prevention in general population to prevent risk of mortality later in life

Study on self-medication among 2nd year medical students

Background: Self-medication is use of medicines by individuals to treat self-recognized symptoms and illness. Self-medication is a common type of self-care behavior in the general public, but medical students differ in such practice, as they have knowledge about drugs and diseases.Methods: The present study involved 100 2nd year final term medical students in “Shivamogga Institute of Medical Sciences,” Shivamogga, Karnataka. Study was questionnaire based, and the results were analyzed by descriptive statistical methods.Results: In our study, 57% were female, and 43% were male. About 60% had knowledge about over the counter (OTC) drugs and considered Ayurveda drugs also OTC drugs. 25% considered self-medication entirely safe, whereas 61% considered self-medication have advantages. Self-medication was preferred by 72% as they felt that there is no need to consult health care professionals for a simple ailment. Self-medication was practiced by 62% students, among which 86% were appropriate, and 48% among them utilized knowledge from previous consultation. In 28% fever was the most common condition and paracetamol was the most commonly used drug.Conclusions: Self-medication was widely practiced among the students. They had good knowledge of OTC drugs. The practice of self-medication was almost appropriate. In general self-medication must be accompanied by appropriate information. Educating benefits and risks of self-medication is very much needed for medical students and the public now a day

Prevalence and Correlates of Tobacco Use Among School-Going Adolescents in Madagascar

Approximately 90% of adults start smoking during adolescence, with limited studies conducted in low-and-middle-income countries where over 80% of global tobacco users reside. The study aims to estimate prevalence and identify predictors associated with adolescents\u27 tobacco use in Madagascar. We utilized tobacco-related information of 1184 school-going adolescents aged 13-15 years, representing a total of 296,111 youth from the 2008 Madagascar Global Youth Tobacco Survey to determine the prevalence of tobacco use. Gender-wise multivariable logistic regression models were conducted to identify key predictors.Approximately 19% (30.7% males; 10.2% females) of adolescents currently smoke cigarettes, and 7% (8.5% males and 5.8% females) currently use non-cigarette tobacco products. Regardless of sex, peer smoking behavior was significantly associated with increased tobacco use among adolescents. In addition, exposures to tobacco industry promotions, secondhand smoke (SHS) and anti-smoking media messages were associated with tobacco use. The strong gender gap in the use of non-cigarette tobacco products, and the role of peer smoking and industry promotions in adolescent females\u27 tobacco use should be of major advocacy and policy concern. A comprehensive tobacco control program integrating parental and peer education, creating social norms, and ban on promotions is necessary to reduce adolescents\u27 tobacco use

The distribution of apolipoprotein E in mouse olfactory epithelium

Previous studies from our laboratory suggest that apolipoprotein (apoE), a lipid transporting protein, facilitates olfactory nerve regeneration. We have shown that apoE is enriched in the olfactory nerve and around the glomeruli of the olfactory bulb (OB). The studies reported herein were undertaken to identify possible sources of apoE in the olfactory epithelium (OE). Immunoblotting results revealed apoE expression in the OE of wild-type (WT) mice, but not in apoE deficient/knockout (KO) mice. Immunohistochemical studies revealed that the perikarya and processes of sustentacular (Sus) cells expressed apoE-like immunoreactivity. Minimal neuronal apoE immunostaining was seen, although apoE was observed in the interstial spaces between olfactory receptor neurons (ORN). Substantial apoE-like immunoreactivity was localized to the endfeet and terminal process of Sus cells surrounding the basal cells. Double labeling immunocytochemical studies confirmed that the cell bodies and endfeet of Sus cells expressed high levels of apoE. The endothelial cells of blood vessels were intensely stained for apoE in the lamina propria. Cells forming Bowman’s gland also immunostained for apoE. The apoE staining in the nerve fascicles was less intense, but was uniformly distributed throughout the core of the nerve bundles. Heavily stained cells, probably ensheathing glia, surrounded the nerve fascicles. These results revealed that apoE is expressed in the adult OE and lamina propria at strategic locations where it could facilitate the differentiation, maturation and axonal growth of the ORN, perhaps by recycling lipids from degenerating ORN for use by growing axons

Validation of the Waterpipe Tolerance Questionnaire Among Jordanian School-Going Adolescent Waterpipe Users

INTRODUCTION: Waterpipe use among adolescents has been increasing progressively. Yet no studies were reported to assess the validity and reliability of nicotine dependence scale. The current study aims to assess the validity and reliability of an Arabic version of the modified Waterpipe Tolerance Questionnaire WTQ among school-going adolescent waterpipe users. METHODS: In a cross-sectional study conducted in Jordan, information on waterpipe use among 333 school-going adolescents aged 11-18 years was obtained using the Arabic version of the WTQ. An exploratory factor analysis and correlation matrices were conducted to assess validity and reliability of the WTQ. RESULTS: The WTQ had a 0.73 alpha of internal consistency indicating moderate level of reliability. The scale showed multidimensionality with items loading on two factors, namely waterpipe consumption and morning smoking. CONCLUSION: This study report nicotine dependence level among school-going adolescents who identify themselves as waterpipe users using the WTQ
