Background: Cervical cancer is common among women worldwide. A multitude of risk factors aggravate the disease. This study was conducted to: (1) determine the prevalence and (2) make a comparative analysis of the socio-demographic and behavioural risk factors of cervical cancer and knowledge, attitude and practice between rural and urban women of North Bengal, India. Study Design: Community-based cross-sectional study. Methods: A survey (first in North Bengal) was conducted among 133 women in a rural area (Kawakhali) and 88 women in an urban slum (Shaktigarh) using predesigned semi-structured questionnaires. The respondents were informed of the causes (including HPV), signs and symptoms, prevention of cervical cancer and treatment, and the procedure of the PAP test and HPV vaccination. Results: The prevalence of risk factors like multiparity, early age of marriage, use of cloth during menstruation, use of condom and OCP, early age of first intercourse was 37.2%, 82%, 83.3%, 5.4%, 15.8% and 65.6% respectively. Awareness about the cause, signs and symptoms, prevention of cervical cancer, PAP test and HPV vaccination was 3.6%, 6.3%, 3.6%, 9.5% and 14.5% respectively. Chi-square testing revealed that in the study population, significant differential at 5% exists between rural and urban residents with respect to number of children, use of cloth/sanitary napkins, family history of cancer and awareness regarding causes of cervical cancer. Regarding KAP, again using chi-square tests, surprisingly, level of education is found to be significant for each element of KAP in urban areas in contrast to complete absence of association between education and elements of KAP in rural areas. Conclusions: A large number of risk factors were present in both areas, the prevalence being higher in the rural areas. The level of awareness and role of education appears to be insignificant determinants in rural compared to urban areas. This pilot study needs to be followed up by large scale programmes to re-orient awareness campaigns, especially in rural areas.

Background: The objective of this study is to determine the effect of nursing education on awareness of risk factors for colorectal cancer. Materials and Methods: In this descriptive study, the sample is consisted of 132 volunteer students studying in the 1st and 4th grades of School of Health Nursing Department during the fall semester of 2014-2015. Data were collected via a questionnaire including information on the socio-demographic features of the participants and the correlating risk factors of colorectal cancer, prepared by researchers in view of the literature. The questionnaire was distributed to students and completed during class time. Before presenting the questionnaires to the respondents, informed consent was obtained from each. The data obtained were analyzed with a statistical package (SPSS). At first, a Kolmogorov-Smirnow test was performed on the research data. However, since it was seen that variables did not have a normal distribution, the Wilcoxon Signed Ranks Test was applied. P values of <0.05 were considered statistically significant. Percentages, means and standard deviations were also utilized for evaluation. Results: Of the total of 132 students participating in this study, 85.6% (n=113) were female, and 14.4% (n=19) were male. The average age was $20.5{\pm}2.04$. 54.5 % of the students (n=72) were 4th graders and 45.5 % (n=60) were first graders. Total score averages of first graders on risk awareness was $X=12{\pm}7.24$, and fourth graders was $X=16.93{\pm}7.71$. The difference between these two scores were found to be statistically significant (Z= -9,333; p=0.000). Conclusions: Nursing education was found out to have a positive influence on the students' awareness of risk factors for colorectal cancer.

Purpose: The purpose of this study was to examine the frequency and the course of delirium, and identify risk factors for the development of delirium in surgical intensive care unit (SICU). Methods: Subjects older than 19 years admitted to the SICU were recruited. After informed written consent, enrolled subjects had baseline cognitive and functional assessments. Subjects were assessed daily for delirium using the Confusion Assessment Method-ICU (CAM-ICU). Results: During the study period, 110 patients were enrolled. The overall incidence of delirium was 20% (22/110). The average time to onset of delirium was 3.04(${\pm}1.25$) days. Several variables were associated with an increased risk of delirium including older age (p<.05), higher admission APACHE II score (p<.001), use of opioid and analgesics (p<.01), using physical restraints (p<.001), and intraoperative hypotension (p<.05). In a multivariate logistic regression model, using physical restraints (p<.001), intraoperative hypotension (p<.05), and older age (p<.05) remained significant predictors of the delirium development. Conclusion: Using physical restraints, intraoperative hypotension and older age was strongly associated with development of delirium in the SICU. Prevention measures need to focus on identifying patients at higher risk for delirium development.

Diabetes, a comprehensive genetic disease, is principally due to the deregulation of glucose levels in the blood. In addition to contemporary epidemiological studies, systematic substantiation suggests that long-term diabetes leads to cancers due to a variety of reasons. In this study, blood samples were collected with informed consent from confirmed type I diabetic (T1DM, n=25) and type II Diabetic patients (T2DM, n=25) with equal numbers of controls. Further depending on the lifestyle habits they were subdivided into smokers/non-smokers and alcoholics/non-alcoholics. Chromosomal assays were performed for these cases and it was found that there was a significant increase in chromosomal aberration frequency in diabetic patient groups who are exposed to smoking and alcohol than that of normal diabetic groups (T1DM and T2DM). On the other hand, patient groups who were non-smoking and non-alcoholics also showed higher chromosomal aberrations when compared to that of controls. While the mechanisms for these increased chromosomal aberrations in diabetic groups are not clear, they may be due to increased oxidative stress leading to oxidative damage and resulting in genomic instability, which in turn may contribute to an increased risk for cancer.

Though implant treatment is considered as a common treatment option for edentulous patients, there have been few studies on the temporomandibular disorder (TMD) related with implant treatment. The purposes of this study were to evaluate the relevance of TMD to the implant patients and to evaluate the risk factors of TMD in relation with implant treatment. For the evaluation of various risk factors of TMD in relation with implant therapy, clinical evaluation focused on patient factors and implant factors. From a group of 694 patients, 25 patients (3.6 %) were included in this study. The majority of the patients were included in the asymptomatic 'adaptive' group. Parafunction was detected in 11 patients, 8 patients were male. Four patients having parafunction showed complications such as implant failure or fracture of the suprastructure. From the results, it is possible that TMJ related symptoms are developed or aggravated after implant therapy, which requires relatively more chair time; so TMJ examination should be included in the pre-operative evaluation for dental implant patients. Also, it is important to treat patients after they sign an informed consent that includes a detailed explanation on the possibility of TMD during treatment.

Number of elderly patients requiring nerve blocks have been increasing in recent years. We had two elderly patients who suffered stroke one day and three days after lumbar facet joint block and lumbar single epidural block respectively. Both patients due to their advanced age had potential risk factor to suffer one or more of the following; stroke, hypertension, and diabetes mellitus. Due to our experience with these patients, we suggested the following: (1) Nerve blocks should be reconsidered for elderly patient who posesses a potential risk factor to suffer a stroke. (2) Prior to invasive block administration of mild sedatives or analgesics may provide beneficial effects for patients with hypertension. (3) Adequately informed consent must be fully discussed time of consultation with patient scheduled for nerve block especially for elderly and risky patient.

This study aims to examine the dynamics of price changes and trading volume of Kuala Lumpur Options and Financial Futures Exchange (KLOFFE) from 2000 to 2008. With augmented analysis, our results support two hypotheses. First, under information spillover, our findings support noise traders' hypothesis as the time span for variance of past trading volume to cause variance of current return is found to be asymmetric under bull and bear markets. Second, looking at the dynamic relation between volume and volatility of price changes, our findings support Liquidity-Driven Trade hypothesis as past trading volume and subsequent volatility of return exhibit positive correlation. In terms of investors' behavior in response to the news, we find that investors are more risk taking in bull market and more risk reverse in bear market. Our study suggests that investors should adjust their strategy in the futures market in a dynamic manner as the time span of new information arrival is not consistent. Also, uninformed investors with information asymmetry should expect noninformational trading from informed investors to establish their desired positions for better liquid position.

Background: The industrial revolution that took place in the United Kingdom (UK) between 1760 and 1830 led to profound social change. Occupational medicine was concerned with the diagnosis, treatment, and prevention of occupational diseases, that is, diseases directly caused by exposure to workplace hazards. A similar pattern of development has occurred globally. Methods: A review of relevant literature. Results: The international conceptualization and development of occupational health occurred during the 20th century. A new paradigm for occupational health has emerged that extends the classical focus on what might be termed "health risk management" that is, the focus on workplace hazards and risk to health to include the medical aspects of sickness absence and rehabilitation, the support and management of chronic noncommunicable diseases, and workplace health promotion. Conclusion: The future strategic direction for occupational health will be informed by a needs analysis and a consideration of where it should be positioned within future healthcare provision. What are the occupational health workforce implications of the vision for occupational health provision? New challenges and new ways of working will necessitate a review of the competence and capacity of the occupational health workforce, with implications for future workforce planning.
