Convective heat transfer on an inlet guide vane.

The flow and temperature fields around an inlet guide vane are determined numerically by a CFD method. Outer surface temperatures, heat transfer coefficient distributions, and static pressure distributions are presented. Three different thermal boundary conditions on the vane are analysed. The computed results are compared with experimental data. The governing equations are solved by a finite-volume method with the low Reynolds number version of the k-omega turbulence model by Wilcox implemented. It is found that the calculated results agree best with measurements if a conjugate heat transfer approach is applied and thus this wall condition is recommended for future investigations of film cooling of guide vanes and turbine blades.

Smoking attributable medical expenditures, years of potential life lost, and the cost of premature death in Taiwan.

OBJECTIVE: To estimate the smoking attributable medical expenditures and productivity loss of people aged 35 and over in Taiwan in 2001 from a societal viewpoint. METHODS: A prevalence based approach was used to estimate smoking attributable costs. Epidemiological parameters were obtained from two follow up studies and government statistics. Data on medical care utilisation and expenditure were extracted from the National Health Insurance claim data. RESULTS: Total smoking attributable medical expenditures (SAEs) amounted to USD 397.6 million, which accounted for 6.8% of the total medical expenditures for people aged 35 and over. Mean annual medical expenditures per smoker was USD 70 more than that of each non-smoker. Smoking attributable years of potential life lost (YPLL) totalled to 217,761 years for males and 15,462 years for females, and the corresponding productivity loss was USD 1371 million for males and USD 18.7 million for females. CONCLUSION: Medical expenditures attributable to smoking accounted for 6.8% of the total medical expenditure of people aged 35 and over for the year 2001 in Taiwan. Corresponding YPLL and productivity loss also demand that actions be taken to fight cigarette smoking.

Women and tobacco in Indonesia.

OBJECTIVES: To present a broad exploration of the relationship of women and tobacco in Indonesia and to describe action on tobacco and health specific to women taken by government and non-government agencies. DATA SOURCES: Published and unpublished prevalence surveys, official documents, vernacular newspapers, secondary sources, unstructured interviews, and personal observations. STUDY SELECTION: Data on smoking prevalence among women was primarily sought from official household surveys but several smaller scale local surveys were also examined. The only representative national household data on smoking prevalence from 1995 suggested a national prevalence for occasional and regular smoking of 2.6% for women aged 20 years or older. Smaller, local level surveys had reported rates varying from 4% for junior high school girls, and 2.9% for women undergraduates at a provincial university, to 6.4% of women in a representative sample in Jakarta. Claims that the incidence of female smoking is increasing cannot be confirmed due to an absence of comparable national longitudinal data. CONCLUSION: Although Indonesian women are conspicuous in growing and processing tobacco, their rates of smoking are low in comparison with their male compatriots and internationally. Anecdotal evidence suggests that their disinclination to smoke is commonly attributed to cultural values, which stigmatise women smokers as morally flawed, while at the same time sanctioning smoking by men. Although there is little evidence of tobacco advertising directly targeting women, Indonesian health activists interviewed by the author felt that women are increasingly taking up smoking due to a weakening of stigma and to Western cultural influences. Cultural factors in the low rates of smoking among Indonesian women deserve closer investigation as they have proved to be a major source of health protection, albeit within a stigmatising context. More also needs to be known about the dynamics of female tobacco use in Indonesia and the factors contributing to marked geographical variations in smoking prevalence.

Incidence of multiple sclerosis among First Nations people in Alberta, Canada.

Multiple sclerosis (MS) is thought to be rare among North American aboriginals, although few population-based frequency studies have been conducted. Data from government health databases were used to describe the incidence of MS among First Nations aboriginal people in the province of Alberta compared to the general population from 1994 to 2002. The general population rates were consistently higher than First Nations rates, but were essentially stable across this time span for both groups. For First Nations the MS incidence was 7.6 per 100,000 and 20.6 per 100,000 for the general population in 2002. During 2000-2002 for First Nations the incidence was 12.7 for females and 7.6 for males, with a female-to-male ratio of 1.7:1. During the same period the general population incidence was 32.2 for females and 12.7 for males, with a female-to-male ratio of 2.5:1. The peak incidence for both First Nations and the general population of Alberta was in the age group 30-39 years in 2002. The high incidence rates are consistent with high prevalence rates reported for both groups in 2002: 99.9 per 100,000 for First Nations and 335.0 per 100,000 for the general population. While the MS incidence in First Nations people is lower than in the general population of Alberta, it is not rare by worldwide standards.

Homicide and mental illness in New Zealand, 1970-2000.

BACKGROUND: Homicides by mentally ill persons have led to political concerns about deinstitutionalisation. AIMS: To provide accurate information about the contribution of mental illness to homicide rates. METHOD: Retrospective study of homicide in New Zealand from 1970 to 2000, using data from government sources. 'Mentally abnormal homicide'perpetrators were defined as those found unfitto stand trial, not guilty by reason of insanity, convicted and sentenced to psychiatric committal, or convicted of infanticide. Group and time trends were analysed. RESULTS: Mentally abnormal homicides constituted 8.7% of the 1498 homicides. The annual rate of such homicides was 1.3 per million population, static over the period. Total homicides increased by over 6% per year from 1970 to 1990, then declined from 1990 to 2000. The percentage of all homicides committed by the mentally abnormal group fell from 19.5% in 1970 to 5.0% in 2000. Ten percent of perpetrators had been admitted to hospital during the month before the offence; 28.6% had had no prior contact with mental health services. Victims were most commonly known to the perpetrator (74%). CONCLUSIONS: Deinstitutionalisation appears not to be associated with an increased risk of homicide by people who are mentally ill.

Wiring health care.

Health care is in need of an industrial revolution. To reform health care delivery, improve quality, and address the economic burdens that health care places on business and individuals in this country, we must first have access to the data that will allow us to create meaningful process improvements and reforms. Only by implementing computerized care tools can we gather the data. The government--and Medicare in particular--should fund this effort and use its purchasing power to ensure that our health care infrastructure is brought up to the level that all other key industries demand.

Ontology annotation treebrowser : an interactive tool where the complementarity of medical subject headings and gene ontology improves the interpretation of gene lists.

Gene expression and proteomics analysis allow the investigation of thousands of biomolecules in parallel. This results in a long list of interesting genes or proteins and a list of annotation terms in the order of thousands. It is not a trivial task to understand such a gene list and it would require extensive efforts to bring together the overwhelming amounts of associated information from the literature and databases. Thus, it is evident that we need ways of condensing and filtering this information. An excellent way to represent knowledge is to use ontologies, where it is possible to group genes or terms with overlapping context, rather than studying one-dimensional lists of keywords. Therefore, we have built the ontology annotation treebrowser (OAT) to represent, condense, filter and summarise the knowledge associated with a list of genes or proteins. The OAT system consists of two disjointed parts; a MySQL database named OATdb, and a treebrowser engine that is implemented as a web interface. The OAT system is implemented using Perl scripts on an Apache web server and the gene, ontology and annotation data is stored in a relational MySQL database. In OAT, we have harmonized the two ontologies of medical subject headings (MeSH) and gene ontology (GO), to enable us to use knowledge both from the literature and the annotation projects in the same tool. OAT includes multiple gene identifier sets, which are merged internally in the OAT database. We have also generated novel MeSH annotations by mapping accession numbers to MEDLINE entries. The ontology browser OAT was created to facilitate the analysis of gene lists. It can be browsed dynamically, so that a scientist can interact with the data and govern the outcome. Test statistics show which branches are enriched. We also show that the two ontologies complement each other, with surprisingly low overlap, by mapping annotations to the Unified Medical Language System. We have developed a novel interactive annotation browser that is the first to incorporate both MeSH and GO for improved interpretation of gene lists. With OAT, we illustrate the benefits of combining MeSH and GO for understanding gene lists. OAT is available as a public web service at: http://www.ifm.liu.se/bioinfo/oat.

Lack of clinical utility of cytomegalovirus blood and urine cultures in patients with HIV infection.

OBJECTIVE: To determine the clinical significance of cytomegalovirus (CMV) blood and urine cultures in patients with human immunodeficiency virus (HIV) infection. DESIGN: Inception cohort of patients with HIV infection and CMV culture data. SETTING: Government referral-based research hospital. PATIENTS: A total of 322 HIV-infected patients who had a CMV blood culture and 293 HIV-infected patients who had a CMV urine culture within 7 days of a CD4 determination. MEASUREMENTS: Cytomegalovirus blood and urine culture results; circulating CD4 lymphocyte counts; pathologic or retinopathic findings of CMV disease. RESULTS: Nine of 26 patients (34.6%) with CMV viremia subsequently developed CMV end-organ disease compared with 11 of 74 (14.9%) patients without viremia, (difference, 19.7%; 95% CI, -0.3% to 39.7%). Fifteen of 47 patients (31.9%) with CMV viruria developed end-organ disease compared with 4 of 43 (9.3%) patients without viruria, (difference, 22.6%; CI, 6.7% to 38.5%). Cytomegalovirus culture positivity had poor predictive value for the subsequent development of end-organ disease (35% for viremia and 28% for viruria). Further, patients with proven end-organ disease were often not viremic (45%), but most were viruric (88%). Cytomegalovirus viremia did not correlate with the presence of either fever or weight loss in this patient group. Both blood culture positivity and urine culture positivity varied inversely with the CD4 count (P = 0.0001 for both associations). CONCLUSIONS: The likelihood that a blood or urine culture will be positive in a patient with HIV infection correlates better with immunologic status than with current or future clinical status. Although the absence of CMV viruria may suggest that CMV disease is not present, CMV blood and urine cultures have poor diagnostic and predictive value and therefore should be used primarily for research purposes or drug susceptibility testing and not for making clinical decisions.

Surveillance for polio eradication: current status and lessons learnt--India, 1999.

With the launch of the Universal Immunisation Programme in India in 1985, childhood immunisation was provided to children in all districts of the country in a phased manner by 1990. Surveillance for vaccine preventable diseases (VPD) including polio was started at the same time with monthly reporting from the districts to the Ministry of Health and Family Welfare (MOHFW), Government of India (GOI). In 1995, the Pulse Polio Immunisation (PPI) campaign was launched with the objective of polio eradication. Prior to 1997, surveillance for polio was directed at finding clinical polio cases by passive reporting from health facilities. There was no active surveillance for all cases of acute flaccid paralysis (AFP). In 1996, a scheme for the surveillance of AFP was drawn up. With the support of the Danish and US governments and Rotary International, 59 surveillance medical officers (SMOs) were hired, trained, and posted throughout the country in October 1997 to establish active surveillance of AFP. The number of SMOs was increased to 108 in August 1999. The SMOs along with their government counterparts established 10,069 reporting units nationwide by the end of November 1999 reporting weekly the occurrence of AFP cases to the district, state, and national levels; timely case investigation and collection of stool specimens from AFP cases; linkages to support the polio laboratory network; and extensive training of government counterparts. Data reported to the national level is analysed and put on an internet website which is updated every two weeks. Annualised rates of reported non-polio AFP have increased from 0.22 per 100,000 children aged < 15 years in 1997 to 1.57 in 1999. The number of polio cases associated with isolation of wild poliovirus decreased from 1404 in the third trimester of 1998 to 664 in the third trimester of 1999, yet widespread transmission of wild polioviruses persists throughout the country.

A study of compliance with environmental regulations of ISO 14001 certified companies in Korea.

This article investigates the impact of ISO 14001 certification on the compliance with environmental regulations by Korean companies. The impact of ISO 14001 certification on the industry was studied through a questionnaire survey and the compliance of environmental regulations were investigated using government-released data. The motivation for an environment management system was a result of the current international situation and the need to maintain fair competition. ISO 14001 certification has been recognized as an essential strategy for industrial competition and to improve company/product recognition. The certified and non-certified companies' environmental regulation violation (ERV) rates were 3.5% and 11.6%, respectively, in 1997. In 1998, the ERV rate had an eight-time difference with 1.0% and 8.5% for certified and non-certified companies, respectively. Annual regulation violation rates were reduced from 3.5% in 1997 to 1.0% in 1998 with certified companies and from 11.6% in 1997 to 8.5% in 1998 with their non-certified counterparts, respectively. ISO 14001 certified companies showed more improvement than non-certified companies in regards to environmental performance.

Motor vehicle seat belt restraint system analysis during rollover.

The multi-planar and multiple impact long duration accident sequence of a real world rollover results in multidirectional vehicle acceleration pulses and multiplanar occupant motions not typically seen in a planar crash sequence. Various researchers have documented that, while contemporary production emergency locking seatbelt retractors (ELRs) have been found to be extremely effective in the planar crashes in which they are extensively evaluated, when subjected to multi-planar acceleration environments their response may be different than expected. Specifically, accelerations in the vertical plane have been shown to substantially affect the timeliness of the retractors inertial sensor moving out of its neutral position and locking the seat belt. An analysis of the vehicle occupant motions relative to the acceleration pulses sensed at the retractor location indicates a time phase shift that, under certain circumstances, can result in unexpected seat belt spool out and occupant excursions in these multi-planar, multiple impact crash sequences. This paper will review the various previous studies focusing on the retractors response to these multidirectional, including vertical, acceleration environments and review statistical studies based upon U.S. government collected data indicating a significant difference in belt usage rates in rollover accidents as compared to all other planar accident modes. A significant number of real world accident case studies will be reviewed wherein the performance of ELR equipped seatbelt systems spooled out. Finally, the typical occupant injury and the associated mechanism due to belt spool out in real world accidents will be delineated.

Performance management in small practices.

Performance management, variably referred to as corporate, business, or enterprise performance management, has traditionally been viewed as a strategy to achieve an optimum mix of solvency, quality, safety, and patient satisfaction in large healthcare organizations. Now, however, with the readily available data from government and nonprofit organizations promoting quality health care and affordable business intelligence tools, small practices can adopt management strategies, tools, and techniques once limited to corporate executives. With a modest investment in self-assessment and affordable analysis tools, a small practice can benefit from a scaled-down version of the performance management initiatives in place at the leading health-care organizations.

[Electronic data processing-assisted high dosage therapy with stem cell transplantation at the Donauspital].

Organization of high dose chemotherapy with stem cell transplantation essentially requires EDV-support. "ONCOBASE" has been adapted into the Donauspital network on May 1, 1992. We report about the 2-year clinical experience with ONCOBASE: 1. ONCOBASE effectively supports communication between the ward, ambulance and hospital pharmacy (where all cytostatics are prepared). 2. ONCOBASE provides better surveillance concerning all therapeutic procedures including cytostatic drugs and supportive therapies. 3. ONCOBASE allows the generation of medical letters which include all drugs and supportive therapies delivered. 4. Since ONCOBASE is a database program, all informations concerning the patients are registered. These include cumulative drug doses, information on side effects, blood cell kinetics after previous therapies, kinetics of tumor markers and results of further examinations. 5. ONCOBASE permits rapid data exchange with other hospital networks using the communication data record governed by the "Arbeitskreis für EDV der deutschen Gesellschaft für Hämatoonkologie".

Information for clinical governance: analysis of routine hospital activity data in Wales.

BACKGROUND: Variations in hospital admission rates have been extensively reported for many years, but this evidence has not had a wide impact on clinical practice. Understanding local reasons for high variation to improve quality of healthcare should be a focus of clinical governance. Our aim was to convert routine hospital activity data into information on a category of high-variation, discretionary, hospital admissions and provide a tool for analysis for clinical governors in Local Health Groups (LHG). METHODS: We undertook a cross-sectional analysis of hospital activity data for the 22 LHGs in Wales and 101 general practices in Gwent Health Authority. Hospital spells for 1998-1999 and 1999-2000 were classified into Healthcare Resource Groups (HRGs). Using the systematic component of variation we identified a category of high-variation admissions for which the only plausible explanation was medical discretion. Using scatter plots we compared the proportion of these discretionary admissions with the age-, sex- and deprivation-adjusted standardized admission ratio. (SAR) for each LHG and practice. RESULTS: We found a two-fold variation in SARs between LHGs and a three-fold variation between practices. Mean discretionary activity was 55 per cent (range 50-59 per cent) of total activity for LHGs and 56 per cent (51-62 per cent) for practices. Greatest variation was found for elective admissions. The relation between discretionary admissions and the SAR was identified for each LHG and practice as the starting point for further investigation. CONCLUSION: This method provides useful information to LHG clinical governors to contribute to the process of reducing medical practice variation, increasing equity, improving the quality of care and making more cost-effective use of resources.
