The effect of prenatal factors on the development of colon cancer.

BACKGROUND: There is some evidence that prenatal factors can play a role in the development of colon cancer. Children with an old parent age at the time of birth were observed to develop certain childhood cancers more frequently. OBJECTIVE: This trial was designed to investigate the effects of some prenatal factors on colon cancer risk. Particularly, investigation of the effect of advanced parent age on colon cancer development risk was targeted. MATERIALS AND METHODS: In this study 117 in or out patients diagnosed with colon cancer and 234 control subjects were included. Definitive diagnostic results and dates of diagnosis were determined from pathological reports. Groups were asked for the parent age, smoking habits, sociodemographic, environmental, familial and reproductive traits. The results were compared between the patients and the control group. RESULTS: It was determined that children may have higher risk if mother and father are more than 30 at birth (p = 0.018, p = 0.020). While the mean mother age at birth was 25.6 +/- 5.72 in patients, it was 24.7 +/- 6.90 in the controls. The difference was not statistically significant (p < 0.056). The mean father age at birth was 29.4 +/- 6.58 in patients and 27.4 +/- 7.47 in the controls. The difference was statistically significant (p < 0.001). Smoking of mother was one of the important risk factors of colon cancer (p = 0.044). CONCLUSION: Our data supports that some prenatal factors such as high parental age at birth and mother -smoker may be risk factors for some cancers in children. This is the first study to report that high parental age at birth and exposure to smoke prenatally increase the risk or colon cancer (Tab. 7, Ref. 28).

Health content analysis of organ donation and transplantation news on Turkish television channels and in Turkish print media.

The media affects individuals' behaviors, especially by means of news and advertisements. In this study, we evaluated health content of organ donation and transplantation news in the printed media and on television programs for a 1-year period in Turkey. We examined 2449 news items in 230 newspapers and magazines; 1179 news programs on 45 television channels, all concerning organ donation and transplantation. The news obtained from the Media Pursuit Center were transferred to an electronic file to evaluate the format and content of the news. Nine variables were examined about the scope and the formal characteristics of the news: the publication name, its type, the province, the date, the headline, the title length, the presence of a photograph, or its kind, the news size, and the page number. In the content analysis of the news, we also examined 9 variables: the topic, the message of the headline, the property of the words in the title, the identification of photographs in the news, the age, gender of actors in the news, as well as donor or recipient. In a summary, print media and television channels, failed to show sufficient information about organ donation and transplantation. The percentage of news about organ donation and transplantation was small and mostly negative items in the media. On television channels, sufficient place was not given to organ donation and transplantation. The news in printed media and on television channels was not about motivated or altruistic behavior. The pattern of organ donation and transplantation news is important in terms of perception and comment by the public. Furthermore it directly affects the perception of the news by the reader.

A household study to determine attitudes and beliefs related to organ transplantation and donation: a pilot study in Yapracik Village, Ankara, Turkey.

Rural areas display adverse attitudes toward organ donation. Through a population-based cross-sectional study of people 18 years of age or older in the rural area of Ankara, Yapracik Village, Turkey, we identified the attitudes and beliefs of people related to organ transplantation and organ donation. The research universe included 87 people in 75 households. The research instrument was a questionnaire. None of the respondents had been involved in organ donation. The percentage of willingness to donate an organ was 47% which was significantly associated with younger age, including 34.4% who expressed willingness while alive. Twenty-five percent believed that their religion is adverse to transplantation, 28% thought it would create pain in death, 20% were afraid, and 83% believed in life afterwards, 15% said that their custom and usage were adverse to organ donation, 50% stated that they can accept organ donation from other races, and 65% stated that they can request organs from their friends. Eighty percent thought that organ donation is a gift given to a human; 34% of them stated that they can be a donor while they are alive. Fifty-four percent of respondents stated that they wanted to get information about organ donation and transplantation. Therefore basic educational campaigns targeting the increase of knowledge about organ donation are warranted in the rural population. There is a need to increase awareness about organ donation and transplantation. Findings like those in this study will help campaigns conducted for organ donation.

Dimensions of health professionals-patient interaction.

Health-professional-patient interaction determines the ethical, technical and behavioural aspects of medical care. Modern approaches to medical and health services focus on patients' expectations and satisfaction. The purpose of this study is to determine the main dimensions of relationships between health professionals (doctors and nurses) and elderly patients. Patients, older than 65 years, admitted to a university hospital in the first three months of 1996, comprise the study population. With probability sampling procedures, research data were obtained from 135 patients, discharged from the university hospital, via a questionnaire method. The questionnaire used in this study has 23 items. Reliability and validity of the questionnaire were tested before actual application. To determine the main dimensions of health professional-patient interaction, factor analysis, a multivariate statistical analysis, was performed. The factor analysis extracted three factors describing the dimensions of health-professional patient interactions. The first two factors included the behavioural side of interaction (physician's behaviour and nurse's behaviour).

Technical efficiencies of Turkish hospitals: DEA approach.

This study uses Data Envelopment Analysis to examine the technical efficiencies of 573 Turkish acute general hospitals. Inputs of number of beds, number of primary care physicians, and number of specialists, and how they are used to produce outputs of inpatient discharges, outpatient visits, and surgical operations, are examined. Results illustrate that less than ten percent of Turkish acute general hospitals operate efficiently compared to their counterparts. Inefficient, compared to efficient hospitals, on average utilize 32% more specialists, 47% more primary care physicians, and have 119% more staffed bed capacity. They also produce on average less output. Particularly, 13% less outpatient visits, 16% inpatient hospitalization, and 57% less surgical procedures. Additionally, the validity of DEA is illustrated by comparing it to the ratio analysis method; no discernible differences in the results are found.
