Vaccination policies in the military: an insight on influenza.

Influenza, despite its generally benign clinical course, is accompanied by absenteeism from work, acute suffering and even mortality, mainly in the elderly and in subjects who have high-risk medical conditions. Its prevention consists of strain specific vaccination, which must be repeated annually due to the high antigenic variability of the influenza virus. Influenza may represent an important obstacle to military readiness, particularly when considering its infectivity within closed communities. Despite such epidemiological situations, influenza vaccination is seldom included in the compulsory vaccination programme of the military on a global level. This may be due to several reasons, namely, a lack of confidence in the vaccine's effectiveness, the need for annual administrations (with expansion of economic and organisational efforts), false assumption that influenza is a disease with a minor impact, contradictory results of cost-effectiveness analyses (examples of which have yet to be made specifically for the military environment). The availability of more effective, economic and easy to administer vaccines, together with detailed and tailored cost-effectiveness analyses, may have a beneficial effect on the role the military plays in the fight against influenza across the globe.

A pesticide surface water mobility index and its relationship with concentrations in agricultural drainage watersheds.

An index to benchmark pesticide mobility relevant to surface water runoff and soil erosion (surface water mobility index, or SWMI) was derived based on two key environmental fate parameters: degradation half-life and organic carbon-normalized soil/water sorption coefficient (Koc). Values assigned with the index of each individual compound correlate well with the concentration trend of 13 pesticides monitored in six Lake Erie, USA, tributaries from 1983 to 1991. Regression using a power function of SWMI fits concentration data well at various percentiles in the database for each tributary and all six tributaries combined, with r2 ranging from 0.71 to 0.94 for the concentrations at the 95th percentile. Good agreement was also obtained between SWMI and the time-weighted annual mean concentrations (r2 = 0.67-0.87). Although concentrations at or near peaks tend to be driven by rare hydrological events (intense precipitation immediately after application), SWMI explains the peak concentration data generally well (r2 = 0.53-0.86). The SWMI-concentration relationship was further evaluated with two other pesticide monitoring databases: the U.S. Geological Survey National Water Quality Assessment Program White River Study Unit (1991-1996) at Hazelton, Indiana, USA, and the Syngenta (previously Novartis) Voluntary Monitoring Program with Community Water Systems at the Higginsville City Lake, Missouri, USA (1995-1997). The ability of the proposed SWMI to discriminate pesticide runoff mobility and its correlation with surface water monitoring data can be significant in the development of screening methodologies and data-based models for government agencies and/or practitioners in general facing increasing pressure to assess pesticide occurrence in aquatic environments.

Immunisation and the law: compulsion or parental choice?

A debate has been developing in Nursing Standard on the issue of childhood immunizations. This article adds to the discussion by considering the likelihood of legislation being introduced to make immunisation compulsory in the UK. It also discusses how the courts approach an application for childhood vaccination against the wishes of a parent and the implications for nursing practice of that approach.

A profile of the population enrolled in New York State's Child Health Plus.

BACKGROUND: The recently enacted State Children's Health Insurance Program (SCHIP), designed to provide affordable health insurance for uninsured children, was modeled in part on New York State's Child Health Plus (CHPlus), which was implemented in 1991. All SCHIP programs involve voluntary enrollment of eligible children. Little is known about characteristics of children who enroll in these programs. OBJECTIVES: To provide a profile of children enrolled in CHPlus between 1993 and 1994 in the 6-county upstate New York study area, and to estimate the participation rate in CHPlus. Methods. A parent interview was conducted to obtain information about children, 0 to 6.9 years old, who enrolled in CHPlus in the study area. Two school-based surveys and the Current Population Survey were used to estimate health insurance coverage. Enrollment data from New York State's Department of Health, together with estimates of the uninsured, were used to estimate participation rates in CHPlus. RESULTS: Most children enrolled in CHPlus in the study area were white. Although 17% of all children in the study area who were <13 years old and living in families with incomes below 160% of the federal poverty level were black, only 9% of CHPlus-enrolled children were black. Twenty-one percent of enrolled children were uninsured during the entire year before enrollment and 61% of children had a gap in coverage lasting >1 month. Children were generally healthy; only 4% had fair or poor health. Eighty-eight percent of parents of enrolled children had completed high school or a higher level of education. Parents reported that loss of a job was the main reason for loss of prior health insurance for their child. Most families learned about CHPlus from a friend (30%) or from their doctor (26%). The uninsured rate among children in the study area was approximately 4.1%. By 1993, the participation rate in CHPlus was about 36%. CONCLUSION: Blacks were underrepresented in CHPlus. Because the underlying uninsured rate was relatively low and parental education and family income were relatively high, the effects of CHPlus observed in this evaluation may be conservative in comparison to the potential effects of CHPlus for other populations of children. Participation rates during the early years of the program were modest.

AIDS: family physicians' attitudes and experiences.

A study was developed to examine the current experiences and opinions of a national sample of family physicians with regard to acquired immunodeficiency syndrome (AIDS). The survey response rate was 72.5% (757 questionnaires were returned out of a sample of 1044). Approximately 47% of respondents have cared for an HIV-infected patients. This percentage varied from a low of 31.4% in the Midwest to as high as 56.1% on the East Coast. Thirty-two percent of family physicians practicing in communities of fewer than 2500 have dealt with this illness, while 60% of those in communities of greater than 100,000 have done so. Seventy-seven percent of respondents are willing to provide care to HIV-infected individuals; 62.9% believe that physicians have a right to refuse to care for a patient because he or she is infected with the AIDS virus. Forty percent believe that they would lose patients if it were known that they were caring for an AIDS patient in their office. Finally, the vast majority of those surveyed favor required partner notification and would inform the sexual partner of an HIV-positive patient if the patient refused to do so.
