Retention force of complete palate coverage and palate-less dentures in vitro.

The purpose of this study was to investigate the retention force of complete palate coverage and palate-less dentures made with three polymerization systems (DS system, SR-Ivocap system, microwave polymerization system) in vitro. The retention force between each denture and a polyurethane model by intervening artificial saliva was measured using a tensile tester. In addition, discrepancies between the denture base and the stone cast were measured at several points. The retention force of complete palate coverage and palate-less dentures made with the 3 polymerization systems shows that the DS system had a greater retention force than the SR-Ivocap system and the microwave system. Moreover, the retention force of palate-less dentures was greater than that of complete dentures only in the case of the DS system. The interaction of the polymerization system and the denture type also had a statistically significant effect on the retention force. Dentures made with the DS system had smaller discrepancies compared with dentures processed with the other systems. The retention force correlated very closely with discrepancies at the denture border and the residual ridge.

Evaluation of stigmatizing language and medical errors in neurology coverage by US newspapers.

OBJECTIVES: To analyze US newspaper coverage of neurologic diseases to determine whether stigmatizing language is used in describing patients and examine its sources where found and to examine stories for medical errors. METHODS: A content analysis of newspaper articles was performed for 2003 using the Lexis-Nexis database. Keyword searches for 11 common neurologic conditions were performed for The New York Times and 8 regional newspapers with circulation greater than 200,000. RESULTS: A total of 1203 stories focusing on 11 neurologic conditions were recovered. Newspaper coverage did not reflect disease prevalence (rank correlation, p=-0.009; P=.98). The topics most covered were Alzheimer disease and other dementias (400 stories, 33% of total), which were eventually combined Into 1 category for purposes of data analysis. Conditions with the highest prevalence were among the least covered topics, including migraine (34 stories, 3% of total) and head trauma (19 stories, 2% of total). Stigmatizing language was found in 15% of all stories. Excluding wire stories, the average among locally produced newspaper stories was higher (21%). Stories on epilepsy (30%) and migraine (29%) contained the highest frequency of stigmatizing language. Sources of stigma within a story included reporters (55%), patients (26%), family (17%), and physicians (16%). In an accuracy analysis, 20% of sampled stories contained medical errors or exaggerations, with half of these concerning neurodegenerative conditions. CONCLUSION: A total of 21% of all stories (excluding wire stories) contained language judged stigmatizing, with reporters as the most common source of the stigmatizing language. A total of 20% of analyzed stories had medical errors or exaggerations, the latter most often overstating treatment effectiveness.

Increasing health insurance coverage through an extended Federal Employees Health Benefits Program.

The Federal Employees Health Benefits Program (FEHBP) could be combined with health insurance tax credits to extend coverage to the uninsured. An extended FEHBP, or "E-FEHBP," would be open to all individuals who were not covered through work or public programs and who also were eligible for the tax credits on the basis of income. E-FEHBP also would be open to employees of very small firms, regardless of their eligibility for tax credits. Most plans available to FEHBP participants would be required to offer enrollment to E-FEHBP participants, although premiums would be rated separately. High-risk individuals would be diverted to a separate high-risk pool, the cost of which would be subsidized by the federal government. E-FEHBP would be administered by the states, or if a state declined, by an entity that contracted with the Office of Personnel Management. While E-FEHBP would provide group insurance to people who otherwise could not get it, premiums could exceed the tax-credit amount and some people still might find the coverage unaffordable.

Transitional subsidies for health insurance coverage.

Losing or leaving a job often means losing health insurance. Of all those who have lost private insurance and become uninsured, one-third have either left or lost a job in the recent past. Continuation of coverage subsidies under the Consolidated Omnibus Budget Reconciliation Act (COBRA) of 1985 mitigate only slightly this problem due to the high costs of the group coverage that must be purchased. This paper discusses a proposal to build on the successes of COBRA to extend insurance to this important population. The key components are: a doubling of the length of COBRA entitlement to 36 months; eligibility for workers in all firms, not just those with more than 20 employees, but with a waiting period of one to two years; the establishment of a new COBRA-LOAN program that would offer government loans to help enrollees pay the cost of COBRA while they searched for new opportunities; and forgiveness of repayments after the entitlement period for those with low incomes.

Low-wage workers and health insurance coverage: can policymakers target them through their employers?

Many policy initiatives to increase health insurance coverage would subsidize employers to offer coverage or subsidize employees to participate in their employers' health plans. Using data from the 1997 Robert Wood Johnson Foundation Employer Health Insurance Survey, we contrast "low-wage employers" with all other employers. Employees in low-wage businesses have significantly worse access to employment-based insurance than other employees do; they are less likely to work for an employer that offers insurance, less likely to be eligible if working in a business that offers insurance, and less likely to be enrolled if eligible. Low-wage employers contribute lower shares of premiums and offer less generous benefits than other employers do. Policies that would target subsidies to selected employers to increase insurance offers to low-wage workers are difficult to design, however, because several commonly mentioned employer characteristics (including firm size) are found to be poor indicators of low-wage worker concentration. Programs that would set minimum standards for employer plans to be eligible for "buy-ins" need to base these standards on the less generous terms offered by low-wage employers in order to effectively reach low-wage workers and their dependents.

Tobacco coverage in popular magazines: 1996-1999.

OBJECTIVE: To determine the extent of coverage of tobacco topics, as compared to coverage of health and nonhealth topics, in "general interest" and "health" magazines. METHODS: Lead articles and fillers published from 1996 through 1999 in 9 widely circulated magazines were studied. RESULTS: Less than 1% of all articles and fillers on health topics focused on tobacco topics. A smaller proportion of tobacco articles and fillers, as compared to other health topics, was published in health magazines than in general interest magazines. CONCLUSION: Tobacco is covered less, compared to other health topics, especially in health magazines, than its importance warrants as a threat to health.

HPRC2: A human pangenome reference with near-complete coverage of common genetic variation.

A pangenome reference overcomes the inherent limitation of any individual reference genome by integrating the variation present in a population. We present the Human Pangenome Reference Consortium's (HPRC) Release 2 (HPRC2), an openly available, second phase pangenome that is an approximately fivefold expansion in genome number over HPRC Release 1 (HPRC1) and measurable improvement in genome completeness, contiguity, and accuracy. Selecting samples with a principled algorithm prioritising common variant coverage, HPRC2 contributes 460 haplotypes that together capture over 99% of common variation observed in the All of Us Research Program v8 cohort. Combining high-coverage long and ultra-long reads with modern assemblers and polishers, we produce thousands of telomere-to-telomere (T2T) chromosomes, and relative to HPRC1 halve the number of structurally unreliable regions as well as individual base errors per haplotype. We complement the assemblies with whole genome multiple alignments and gene annotations, and derive formal pangenome coordinate systems for addressing off-reference variation, demonstrating that individual human genomes contain more than one hundred thousand variants not succinctly described with respect to existing reference genomes. We also present the first matched long-read backed pantranscriptome and panepigenome at this scale, provide continuous local-ancestry estimates spanning every genome, and outline a host of new tools and applications that leverage the pangenome resource for improved genomics analysis.

Tuberculin reactivity in a pediatric population with high BCG vaccination coverage.

SETTING: The tuberculin skin test (TST) is often included in diagnostic algorithms for tuberculosis (TB) in children. TST interpretation, however, may be complicated by prior Bacillus Calmette-Guerin (BCG) vaccination. We assessed the prevalence of and risk factors for positive TST reactions in children 3 to 60 months of age in Botswana, a country with high TB rates and BCG coverage of over 90%. METHODS: A multi-stage cluster survey was conducted in one rural and three urban districts. Data collected included demographic characteristics, nutritional indices, vaccination status, and prior TB exposure. Mantoux TSTs were administered and induration measured at 48-72 hours. RESULTS: Of 821 children identified, 783 had TSTs placed and read. Of the 759 children with vaccination cards, 755 (99.5%) had received BCG vaccine. Seventy-nine per cent of children had 0 mm induration, 7% had > or =10 mm induration ('positive' TST), and 2% had > or =15 mm. A positive TST was associated with reported contact with any person with active TB (odds ratio [OR] 1.9; 95% confidence interval [CI] 1.02-3.6), or a mother (OR 5.1; 95% CI 2.1-12.4) or aunt (OR 5.3; 95% CI 2.0-14.0) with active TB. TSTs > or =5 mm (but not > or =10 mm) were associated with presence of a BCG scar. Positive reactions were not associated with age, time since BCG vaccination, clinical signs or symptoms of TB, nutritional status, crowding, or recent measles or polio immunization. CONCLUSION: The TST remains useful in identifying children with tuberculous infection in this setting of high TB prevalence and extensive BCG coverage.

Coverage and quality of oral cancer information in the popular press: 1987-98.

OBJECTIVES: National data show a lack of knowledge and misinformation about oral cancer and its early detection among the general public. A major source of health information is the popular press. For that reason this study reviewed coverage and quality of news items on the topic of oral cancer in the popular press. In addition, the number and types of tobacco advertisements in women and men's magazines were recorded for a one-year period. METHODS: Articles from magazines and newspapers were retrieved from the Magazine Index (1987 to April 1998), Newspaper Abstract (1989 to April 1998) and the Health & Wellness (1987 to April 1998) databases. The articles were analyzed both for adequacy of content and information. RESULTS: A total of 50 articles and news items including oral cancer were identified and analyzed, 18 from newspapers and 32 from magazines. Ninety-four percent of the articles mentioned at least one risk factor for oral cancer. More than half of the articles (56%) identified spit tobacco (chewing tobacco or snuff) as the major risk factor for oral cancer, while far fewer mentioned either cigarettes (32%) or cigars (12%). Over 50 percent of the articles did not mention warning signs for oral cancers. Fourteen percent suggested clinical oral cancer examinations by a health professional; only 8 percent advised the use of self-examination. A total of 417 tobacco advertisements (482 pages) were found among 22 magazines for the one-year period. They included 410 cigarette ads, seven cigar ads, and no spit tobacco ads. CONCLUSIONS: This study demonstrates the lack of coverage about oral cancer in the popular press in the past decade and provides a partial explanation of the public's lack of knowledge and misinformation about oral cancers.

Medicare program; changes to maintenance of effort requirements (section 421 of the Medicare Catastrophic Coverage Act)--HCFA. Notice.

This notice announces the effect on employers of the repeal of section 421 (Maintenance of Effort Provision) of the Medicare Catastrophic Coverage Act of 1988 (MCCA). The enactment of Public Law 101-234 (Medicare Catastrophic Coverage Repeal Act of 1989) on December 13, 1989 repealed many of the provisions of MCCA and restored the Medicare benefit levels to those available prior to January 1, 1989. Consequently, employers are relieved of their Maintenance of Effort responsibilities effective January 1, 1990.

Coverage, technology assessment, and the courts.

Coverage decisions by third-party payers are relying more and more heavily on the conclusions of technology assessment programs about the safety and effectiveness of technologies applied in specific clinical situations. Assessment programs vary markedly in the sophistication and rigor of their methodology. Payers differ as to how such assessment information is integrated into their decision-making processes. Finally, coverage decisions about a specific technology can vary widely across the country.

Americans' health insurance coverage, 1980-91.

The authors of this article have used Current Population Surveys to summarize public and private health insurance trends in the United States over the last 12 years. Key findings include the declining percentage of the non-elderly population with employer-sponsored coverage and increasing numbers of low- and middle-income uninsured. That is, in a period of fast-rising health care costs, the poor and the near-poor in working families have been losing coverage for health care and facing increasing risks of inadequate care and financial loss. These data highlight health care access and financing problems now facing the Nation.
