(National Center for Health Statistics, Centers for Disease Control and Prevention)Spectrometry, Mass, Electrospray Ionization: A mass spectrometry technique used for analysis of nonvolatile compounds such as proteins and macromolecules. The technique involves preparing electrically charged droplets from analyte molecules dissolved in solvent. The electrically charged droplets enter a vacuum chamber where the solvent is evaporated. Evaporation of solvent reduces the droplet size, thereby increasing the coulombic repulsion within the droplet. As the charged droplets get smaller, the excess charge within them causes them to disintegrate and release analyte molecules. The volatilized analyte molecules are then analyzed by mass spectrometry.Tandem Mass Spectrometry: A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization: A mass spectrometric technique that is used for the analysis of large biomolecules.

(1/10392) Screening for cervical cancer: a review of women's attitudes, knowledge, and behaviour.

The United Kingdom (UK) cervical screening programme has been successful in securing participation of a high proportion of targeted women, and has seen a fall in mortality rates of those suffering from cervical cancer. There remains, however, a significant proportion of unscreened women and, of women in whom an abnormality is detected, many will not attend for colposcopy. The present work reviews the psychological consequences of receiving an abnormal cervical smear result and of secondary screening and treatment, and examines reasons for women's non-participation in the screening programme. Psychological theories of screening behavior are used to elucidate women's reactions and to suggest methods of increasing participation, of improving the quality of the service, and of reducing women's anxiety. A literature search identified studies that examine factors influencing women's participation in the screening programme, their psychological reaction to the receipt of an abnormal cervical smear result, and experiences of colposcopy. Reasons for non-participation include administrative failures, unavailability of a female screener, inconvenient clinic times, lack of awareness of the test's indications and benefits, considering oneself not to be at risk of developing cervical cancer, and fear of embarrassment, pain, or the detection of cancer. The receipt of an abnormal result and referral for colposcopy cause high levels of distress owing to limited understanding of the meaning of the smear test; many women believe the test aims to detect existing cervical cancer. The quality of the cervical screening service can be enhanced by the provision of additional information, by improved quality of communication, and by consideration of women's health beliefs. This may result in increased participation in, and satisfaction with, the service.  (+info)

(2/10392) The PRIME study: classical risk factors do not explain the severalfold differences in risk of coronary heart disease between France and Northern Ireland. Prospective Epidemiological Study of Myocardial Infarction.

We are studying the contribution of risk and genetic factors, and their interaction, to the development of ischaemic heart disease (IHD) and other cardiovascular endpoints. The study is prospective, based in three centres in the south, east and north of France and in Northern Ireland. A total of 10,592 men aged 50-59 years were recruited from 1991 to 1993, and examined for evidence of IHD at baseline. Subjects are followed annually by questionnaire. Clinical information is validated from hospital and GP records. Demographic characteristics were similar in all four centres. Body mass index was highest in Strasbourg (mean 27.4 kg/m2 vs. 26.3 kg/m2 in Toulouse and Belfast), but total cholesterol, triglyceride and fibrinogen were highest in Belfast. In Belfast, 6.1% reported having had a coronary angiogram, compared to 3.0% in Toulouse. Conversely, 13.8% in Toulouse reported taking lipid-lowering drugs vs. 1.6% in Belfast. As predicted, a history of myocardial infarction (MI) was highest in Belfast (6.1%) and lowest in Toulouse (1.2%). Some 7.1% of Belfast men reported a medical diagnosis of angina vs. 1.5% in Toulouse. Subjects showing evidence of pre-existing IHD will be studied prospectively but treated in the analysis as an additional variable. These results provide a measure of reassurance that these cohorts are representative of the communities from which they are drawn and provide a reliable baseline for prospective evaluation and cross-sectional comparisons. The levels of the classical risk factors found in this study, particularly when examined in combination, as multiple logistic functions based on previous British studies, are very similar between centres and cannot explain the large differences in the incidence of IHD which exist. Additional risk factors may help explain, at least in part, the major differences in incidence of IHD between these study centres.  (+info)

(3/10392) Coeliac disease detected by screening is not silent--simply unrecognized.

Coeliac disease (CD) is associated with a wide spectrum of clinical presentation and may be overlooked as a diagnosis. There is some evidence that untreated CD is associated with a doubling of mortality, largely due to an increase in the incidence of malignancy and small intestinal lymphoma, which is decreased by a strict gluten-free diet. We studied the clinical features of screening-detected coeliacs compared to age- and sex-matched controls as a 3-year follow-up to a population screening survey, and followed-up subjects who had had CD-associated serology 11 years previously to determine whether they have CD or an increased mortality rate compared to the general population. Samples of the general population (MONICA 1991 and 1983) were screened for CD-associated serology and followed-up after 3 and 11 years, respectively, and assessed by a clinical questionnaire, screening blood tests and jejunal biopsy. Mortality rates for 'all deaths' and 'cancer deaths' were compared in subjects with positive serology in 1983 with reference to the general population. Thirteen coeliacs were diagnosed by villous atrophy following screening, compared to two patients with clinically detected CD, giving a prevalence of 1:122. Clinical features or laboratory parameters were not indicative of CD compared to controls. Subjects with positive serology followed up after 11 years did not have an excess mortality for either cancer deaths or all causes of death. Screening-detected CD is rarely silent and may be associated with significant symptoms and morbidity. In this limited study with small numbers, there does not appear to be an increased mortality from screening-detected CD, although the follow-up may be too short to detect any difference.  (+info)

(4/10392) Faecal occult blood screening and reduction of colorectal cancer mortality: a case-control study.

To estimate the efficacy of screening on colorectal cancer mortality, a population-based case-control study was conducted in well-defined areas of Burgundy (France). Screening by faecal occult blood test prior to diagnosis in cases born between 1914 and 1943 and who died of colorectal cancer diagnosed in 1988-94 was compared with screening in controls matched with the case for age, sex and place of residence. Cases were less likely to have been screened than controls, with an odds ratio (OR) of 0.67 [95% confidence interval (CI) 0.48-0.94]. The negative overall association did not differ by gender or by anatomical location. The odds ratio of death from colorectal cancer was 0.64 (95% CI 0.46-0.91) for those screened within 3 years of case diagnosis compared with those not screened. It was 1.14 (95% CI 0.50-2.63) for those screened more than 3 years before case diagnosis. There was a negative association between the risk of death from colorectal cancer and the number of participations in the screening campaigns. The inverse association between screening for faecal occult blood and fatal colorectal cancer suggests that screening can reduce colorectal cancer mortality. This report further supports recommendations for population-based mass screening with faecal occult blood test.  (+info)

(5/10392) The identification of agreed criteria for referral following the dental inspection of children in the school setting.

AIM: To clarify the function of the school based dental inspection. OBJECTIVE: For representatives of the Community Dental Service, General Dental Service and Hospital Dental Service to identify an agreed set of criteria for the referral of children following school dental inspection. DESIGN: Qualitative research methodology used to establish a consensus for the inclusion of referral criteria following dental screening. SETTING: Ellesmere Port, Cheshire, England. MATERIALS: A Delphi technique was used to establish a consensus amongst the study participants on the inclusion of nine possible criteria for referral following dental screening. All participants scored each criterion in the range 1-9, with a score of 1 indicating that referral of individuals with the condition should definitely not take place, and a score of 9 indicating referral should definitely take place. Referral criteria were accepted only if they achieved a group median score of 7 or more, with an interquartile range of three scale points, with the lower value being no less than 7. RESULTS: Four of the nine possible criteria met the agreed group standard for inclusion: 'Sepsis', 'Caries in the secondary dentition', 'Overjet > 10 mm', and 'Registered & caries in the permanent dentition'. CONCLUSION: It is possible to agree clear criteria for the referral of children following the school dental inspection.  (+info)

(6/10392) Special medical examination program reform proposal in Korea.

We are at a time when reform in the special medical examination program in keeping with the changing times is desperately needed because the common perception of workers, employers, and medical examination facilities is "special medical examination is merely ritualistic and unproductive." Therefore, we have tried to set forth the basic structure for reforming the special medical examination program by taking a close look at the management status of the current program and analyzing its problems. The specifics of the special medical examination program reform proposal consist of three parts such as the types, health evaluation based on occupational medicine, and the interval, subject selection, items and procedure. Pre-placement medical examination and non-periodic medical examinations-as-necessary are introduced newly. Health evaluation based on occupational medicine consists of classification of health status, evaluation of work suitability, and post-examination measure. Details regarding the medical examination interval, subject selection, items and procedure were changed.  (+info)

(7/10392) Screening Mammography Program of British Columbia: pattern of use and health care system costs.

BACKGROUND: The use of mammography for screening asymptomatic women has increased dramatically in the past decade. This report describes the changes that have occurred in the use of bilateral mammography in British Columbia since the provincial breast cancer screening program began in 1988. METHODS: Using province-wide databases from both the breast cancer screening program and the provincial health insurance plan in BC, the authors determined the number and costs of bilateral mammography services for women aged 40 years or older between Apr. 1, 1986, and Mar. 31, 1997. Unilateral mammography was excluded because it is used for investigating symptomatic disease and screening abnormalities, and for follow-up of women who have undergone mastectomy for cancer. RESULTS: As the provincial breast cancer screening program expanded from 1 site in 1988 to 23 in 1997, it provided an increasing proportion of the bilateral mammographic examinations carried out each year in BC. In fiscal year 1996/97, 65% of bilateral mammographic examinations were performed through the screening program. The cost per examination within the screening program dropped as volume increased. Thirty percent more bilateral mammography examinations were done in 1996/97 than in 1991/92, but health care system expenditures for these services increased by only 4% during the same period. In calendar year 1996, 21% of new breast cancers were diagnosed as a result of a screening program visit.

PROBLEM ADDRESSED: First Nations women in British Columbia, especially elders, are underscreened for cancer of the cervix compared with the general population and are much more likely to die of the disease than other women. OBJECTIVE OF PROGRAM: To develop a pilot program, in consultation with community representatives, to address the Pap screening needs of First Nations women 40 years and older on a rural reserve. MAIN COMPONENTS OF PROGRAM: Identification of key links to the population; consultation with the community to design an outreach process; identification of underscreened women; implementation of community Pap screening clinics; evaluation of the pilot program. CONCLUSIONS: We developed a Pap screening outreach program that marked a departure from the usual screening approach in the community. First Nations community health representatives were key links for the process that involved family physicians and office staff at a local clinic on a rural reserve. Participation rate for the pilot program was 48%, resulting in an increase of 15% over the previously recorded screening rate for this population. More screening clinics of this type and evaluation for sustainability are proposed.  (+info)
