Minnesota Colleagues in Caring Collaborative.

Greater mobility, new practice settings, a tight labor market, high expectations for nursing skills in both acute and ambulatory settings, and an uncertain future for higher education--what do these spell for nursing employment? Managed care in Minnesota has led to greater diversity in practice settings and professional activities for nurses. Nursing has proved resilient to changes in this environment so far, but what about the future? Minnesota Colleagues in Caring is positioning itself through regional service/education partnerships to be proactive in nursing's future in Minnesota.

Validation of the Minnesota Leisure Time Physical Activity Questionnaire In Spanish Women. Investigators of the MARATDON Group.

PURPOSE: Regular physical activity (PA) is associated with lower risk for several chronic diseases. It is important to validate PA measurement instruments in different populations. The objective was to validate the Minnesota leisure time PA questionnaire among Spanish women. METHODS: A cross-sectional study with quota sampling was designed. Two PA groups (active, expending less than 301 MET-min x d(-1) in PA, and very active, expending more than 300 MET-min x d(-1)) and two age groups (18-40 and 41-60 yr) were defined. The Minnesota questionnaire was administered to obtain total energy expenditure in leisure time PA (EEPAtotal) and classified according to the intensity of the different types of PA (EEPAheavy, EEPAmoderate, and EEPAlight). The 250 women recruited performed an exercise test to assess fitness. RESULTS: Spearman correlation coefficients among EEPAtotal, EEPAheavy, EEPAmoderate, EEPAlight, and fitness were 0.39, 0.51, 0.13, and 0.02, respectively. Multiple linear regression model adjusted by the different EEPAs and age accounted for 46% of fitness variability. Besides age, only EEPAmoderate and EEPAheavy were associated with fitness. CONCLUSION: The Spanish version of the Minnesota questionnaire is a valid instrument for measuring leisure time PA performed in the last year in Spanish women aged 18-60 yr. Moderate and heavy physical activity are adequately assessed whereas light physical activity practice assessment may be questionable.

The home care practice and attitudes of Minnesota family physicians.

OBJECTIVE: Assess home care practice and attitudes of Minnesota family physicians (FPs). DESIGN: Mailed survey. SETTING: State of Minnesota. PARTICIPANTS: Members of the Minnesota Academy of Family Physicians, 80% of the FPs practicing in the state. INTERVENTION: A 55-item mailed, self-complete questionnaire regarding general practice and personal physician characteristics (18 questions), specific questions regarding geriatric and home care practice and related attitudes (37 questions); up to four reminder or follow-up surveys were sent. MAIN OUTCOME MEASURES: Descriptive summary of FP home care practice and attitudes. RESULTS: Eighty percent of surveys were completed, 76% of responding physicians made at least one home visit in the previous year, and 92% of home visits were to geriatric patients. Discriminant function analysis identified six significant (P less than 0.001) variables that explained 52% of the variance (r2 = 0.52, Wilks Lambda = 0.48) in home visiting behavior between frequent home visiting FPs (greater than 24 visits/year) and non-visiting FPs. FPs most likely to do home visiting were older and tended to have small group or solo practices in rural settings. CONCLUSION: The survey documented continued decline (from previously published surveys) of physician home visiting behavior and widespread dissatisfaction with reimbursement. However, attitudes regarding home care provided by other professionals were highly positive.

BIOCHEMICAL STUDIES OF THE SMOOTH-ROUGH MUTATION IN SALMONELLA MINNESOTA.

Lüderitz, O. (Max-Planck-Institut für Immunbiologie, Frieburg, Germany), H. J. Risse, H. Schulte-Holthausen, J. L. Strominger, I. W. Sutherland, and O. Westphal. Biochemical studies of the smooth-rough mutation in Salmonella minnesota. J. Bacteriol. 89:343-354. 1965.-A comparative study of the O antigen from the smooth strain of Salmonella minnesota and of the two R antigens derived from two rough forms of S. minnesota (strains R 60 and R 345) has been carried out. The O-specific polysaccharide of the smooth form is composed of heptose, galactose, glucose, glucosamine, galactosamine, and ketodeoxyoctanoate (KDO). R 60 polysaccharide contains KDO, heptose, galactose, glucose, and glucosamine, whereas the R 345 polysaccharide contains only KDO, heptose, galactose, and glucose. Serologically, R 345 and R 60 polysaccharides belong to serogroups R I and R II, respectively. Enzymatic studies revealed that the acetylgalactosamine-synthesizing enzyme, uridine diphosphate-N-acetylglucosamine-4-epimerase, is present in wild-type and R 345 cells but is absent from R 60 cells. Two distinct polysaccharides were obtained from the R 345 cells: a polysaccharide derived from the R antigen (lipopolysaccharide) containing no galactosamine and exerting R specificity, and a soluble polysaccharide containing galactosamine and exerting O specificity. The structure of O and R antigens is discussed, together with the general significance of the results for the biosynthesis of the O antigens of the genus Salmonella.

Geographic, clinical, serologic, and molecular evidence of granulocytic ehrlichiosis, a likely zoonotic disease, in Minnesota and Wisconsin dogs.

Seventeen Minnesota and Wisconsin dogs with granulocytic ehrlichosis were studied. The diagnoses were made by finding ehrlichia morulae in peripheral blood neutrophils. Eight dogs were studied retrospectively, and nine dogs were studied prospectively. The medical records of all dogs were reviewed. Eighty-eight percent of the dogs were purebred and 76% were spayed females. The median age was 8 years. Sixty-five percent of the cases were diagnosed in October and November. Fever and lethargy were the most common clinical signs. The most frequent laboratory findings were lymphopenia, thrombocytopenia, elevated activities of serum alkaline phosphatase and amylase, and hypoalbuminemia. No dogs seroreacted to Ehrlichia canis or Ehrlichia chaffeensis antigens, which are cross-reactive. Seventy-five percent of the dogs tested during the acute phase of disease and 100% of the dogs tested during convalescence were seropositive for E. equi antigens. Granulocytic ehrlichial 16S rRNA gene DNAs from six dogs were amplified by PCR. Sequence analysis of a 919-bp sequence of the ehrlichial 16S rRNA gene amplified by PCR from the blood of two dogs revealed the agent to be identical to the agent of human granulocytic ehrlichiosis in Minnesota and Wisconsin and to be very similar to E. equi and Ehrlichia phagocytophila and less similar to E. canis, Ehrlichia ewingii, and E. chaffeensis. The geographic, clinical, serologic, and molecular evidence indicates that granulocytic ehrlichiosis in Minnesota and Wisconsin dogs is not caused by E. ewingii, but suggests that it is a zoonotic disease caused by an agent closely related to E. equi and that dogs likely contribute to the enzootic cycle and human infection.

Relation between policies and work related assault: Minnesota Nurses' Study.

AIMS: To assess the relation between violence prevention policies and work related assault. METHODS: From Phase 1 of the Minnesota Nurses' Study, a population based survey of 6300 Minnesota nurses (response 79%), 13.2% reported experiencing work related physical assault in the past year. In Phase 2, a case-control study, 1900 nurses (response 75%) were questioned about exposures relevant to violence, including eight work related violence prevention policy items. A comprehensive causal model served as a basis for survey design, analyses, and interpretation. Sensitivity analyses were conducted for potential exposure misclassification and the presence of an unmeasured confounder. RESULTS: Results of multiple regression analyses, controlling for appropriate factors, indicated that the odds of physical assault decreased for having a zero tolerance policy (OR = 0.5, 95% CI 0.4 to 0.8) and having policies regarding types of prohibited violent behaviours (OR = 0.5, 95% CI 0.3 to 0.9). Analyses adjusted for non-response and non-selection resulted in wider confidence intervals, but no substantial change in effect estimates. CONCLUSIONS: It appears that some work related violence policies may be protective for the population of Minnesota nurses.

Characteristics of rhizobia nodulating beans in the central region of Minnesota.

Until recently, beans (Phaseolus vulgaris L.) grown in Minnesota were rarely inoculated. Because of this, we hypothesized that bean rhizobia collected in Minnesota would either share characteristics identifiable with Rhizobium etli of Mesoamerican or Andean origin, introduced into the region as seed-borne contaminants, or be indigenous rhizobia from prairie species, such as Dalea spp. The latter organisms have been shown to nodulate and fix N2 with Phaseolus vulgaris. Rhizobia recovered from the Staples, Verndale, and Park Rapids areas of Minnesota were grouped according to the results of BOXA1R-PCR fingerprint analysis into 5 groups, with only one of these having banding patterns similar to 2 of 4 R. etli reference strains. When representative isolates were subject to fatty acid - methyl ester analysis and 16S rRNA gene sequence analysis, the results obtained differed. 16S rRNA gene sequences of half the organisms tested were most similar to Rhizobium leguminosarum. Rhizobia from Dalea spp., an important legume in the prairie ecosystem, did not play a significant role as the microsymbiont of beans in this area. This appears to be due to the longer time needed for them to initiate infection in Phaseolus vulgaris. Strains of Rhizobium tropici IIB, including UMR1899, proved tolerant to streptomycin and captan, which are commonly applied as seed treatments for beans. Local rhizobia appeared to have very limited tolerance to these compounds.

Amplified fragment length polymorphism to detect clonal diversity and distribution of Mycobacterium avium subspecies paratuberculosis in selected Minnesota dairy cattle.

The molecular ecology of Mycobacterium avium subspecies paratuberculosis (MAP), the causative agent of Johne's disease, is not well understood in the United States. In this study, a DNA fingerprinting method, amplified fragment length polymorphism (AFLP), was used to subtype the pathogen and assess the clonal diversity of MAP in Minnesota dairy herds. Fifty-six fecal culture test-positive isolates from various Minnesota counties and culture dates were analyzed in this study. The AFLP identified 11 profiles with 50% of isolates representing 1 major profile. The major profile was distributed across the state. The genetic diversity of bovine MAP clones in Minnesota based on AFLP analysis of this data appears to be relatively low.

Computerized placement in dentistry: the Minnesota experience.

In response to identified manpower information and service requirements, the Minnesota Dental Association, the board of dentistry, and the University of Minnesota School of Dentistry established the Dental Information Service Center in 1972. One major effort of the center was to develop a computerized placement service for dentistry in the state. This service was recently subjected to a user evaluation. Of 1,030 delivered questionnaires, 431 were returned in response to a single mailing. The respondents included 216 employers and 215 employees, including dentists seeking positions. Dental employers generally found the system to be their most successful strategy in the search for employees; from the perspective of employees, other sources such as personal contact competed with the computerized system as the most successful source of information. Evidence from this evaluation indicates that the computerized placement experience in Minnesota has been quite positive. Dentists have relied on the service somewhat more heavily than other dental occupational groups, possibly because alternate sources of information traditionally have not served the health professions. Overall satisfaction ran quite high, and an overwhelming majority of the respondents thought that the service should be continued and expanded to either a regional or a national level.

Parental knowledge and attitudes of Minnesota laws concerning adolescent medical care.

OBJECTIVE: To determine parents' knowledge and attitudes of medicolegal issues affecting adolescent medical care. DESIGN: An anonymous, mailed survey with 16 questions concerning Minnesota consent and confidentiality laws that affect adolescents' medical care. SETTING: A community of >70 000 in rural, southeastern Minnesota. PARTICIPANTS: Parents of 600 randomly selected 7th- through 12th-grade public school students. RESULTS: Two hundred eighty-eight (48%) parents returned the surveys. Parents achieved a median score of 18.8% (range, 0%-93.8%) correct on a test of knowledge. Opinion was a median of +0.3 on a scale where -1 signified "a bad law," 0 signified "neither a good nor bad law," and +1 signified "a good law." Four questions, however, generated a more intense response. Seventy-seven percent of parents reported that, as a whole, the laws in the survey had no effect on them and/or their children. CONCLUSIONS: These results suggest that parents are not knowledgeable of Minnesota laws that affect adolescent medical care. Overall opinion of these laws was mildly positive, with notable exceptions. Parents also lack a sense of impact of laws affecting adolescent medical care. Lack of knowledge and the presence of certain attitudes allow for identification of issues that clinicians should address by incorporating medicolegal education into the care of adolescents and their families. These results are especially timely in light of the Parental Rights and Responsibilities Act under consideration in Congress, which would provide parents greater authority over their children's medical care.

Evaluation of action thresholds and spinosad for lepidopteran pest management in Minnesota cabbage.

Action thresholds, based on the percentage of plants infested, for the lepidopteran pest complex in fresh-market cabbage Brassica oleracea variety capitata were evaluated in 1996 and 1997 in southern Minnesota. Three lepidopteran pests are common in Minnesota, including the imported cabbageworm, Pieris (=Artogeia) rapae (L.), diamondback moth, Plutella xylostella (L.), and the cabbage looper, Trichoplusia ni (Hübner). Most of the thresholds tested included all three pests. However, because T. ni is often the most consistent and damaging pest in Minnesota, two thresholds were based solely on the percentage of plants infested with T. ni eggs and larvae. Action thresholds were also evaluated for their compatibility with a recently labeled biologically based insecticide, spinosad, and a conventional pyrethroid, permethrin. Although all three lepidopteran pests were present in both years of the study, P. rapae provided most of the pest pressure in 1996, and T. ni was most abundant in 1997. Compared with the 0% larval infestation treatment (approximately weekly sprays from early heading to harvest), all action thresholds resulted in less insecticide use (17- 80%), while maintaining high levels of marketability. Despite variable pest pressure between years, one of the thresholds based solely on T. ni (10% of plants infested with eggs or larvae) performed as well as each of the thresholds based on all three species combined. For both years, and compared with a weekly spray schedule from early heading to harvest (average of 5.5 sprays per year), use of the 10% T. ni egg or larval threshold resulted in an average of 36.5% (3.5 sprays) and 65% (2.0 sprays) fewer applications of spinosad and permethrin, respectively, with no significant loss in marketability. The results indicate that a variety of incidence-based action thresholds can be used to ensure the production of high-quality cabbage in the midwestern United States with only minimal applications of spinosad or permethrin.

The social and economic costs of alcohol abuse in Minnesota, 1983.

Alcohol abuse in the State of Minnesota has an impact on health, health care resources, and the economy. Alcohol abuse was related to 3.3 per cent (1,150) of deaths in Minnesota in 1983; of these, almost one-third were the result of fatal injuries. Alcohol abuse contributed to 12 per cent (33,909) of all years of potential life lost, two-thirds of which were secondary to injury. The estimated cost of alcohol abuse ranged from $1.4 billion to $2.1 billion, representing from 2.8 per cent to 4.3 per cent of all personal income of Minnesotans, from 32 per cent to 50 per cent of State expenditures, and from 26 to 39 times the alcohol excise tax revenues generated in 1983. Alcohol-related direct medical care costs were estimated to be at least $216 million, 3.8 per cent of Minnesota medical costs for 1983. Costs of reduced on-the-job productivity and short-term absenteeism related to alcohol abuse were estimated to be between $630 million and $1.2 billion. The documentation of the costs of alcohol abuse is an important step in the campaign to reduce alcohol-related deaths, morbidity, and health care costs.

Changes in the distribution of physicians in rural areas of Minnesota, 1965-85.

The purpose of this study was to assess changes in the physician-population ratio in non-SMSA Minnesota counties between 1965 and 1985 using county specific data published by the American Medical Association. The physician-population ratio actually decreased by 2 per cent for primary care physicians and by 11 per cent for family practitioners in the non-SMSA counties. The large increase in the number of physicians in Minnesota has not translated into improved access to primary care physicians in Minnesota's rural areas.

Impact of the Minnesota Parental Notification Law on abortion and birth.

BACKGROUND: The impact of the Minnesota Parental Notification Law on abortion and birth was examined. METHODS: Using linear models, outcome parameters were compared before and after enactment of the law. Time by age group interactions also were examined. RESULTS: The pre-enactment to post-enactment change in the Minnesota abortion rate reflected a greater decline for minors (less than or equal to 17 years old) than for 18-19 year-olds (who were not under the law). An increase in abortion rate occurred for women ages 20-44. The law appeared to have had no impact on birth rate in minors. Following the enactment of the law, the rate of early abortions (less than or equal to 12 weeks) declined among minors more than the rate of late abortions (greater than 12 weeks). This resulted in a pre-enactment to post-enactment increase in the ratio of late-to-early abortions among minors. CONCLUSIONS: These data suggest that parental notification facilitated pregnancy avoidance in 15-17 year-old Minnesota women. Abortion rates declined unexpectedly while birth rates continued to decline in accordance with a long-term trend.

Characteristics of adolescent work injuries reported to the Minnesota Department of Labor and Industry.

OBJECTIVES: The purpose of the study was to provide descriptive data and incidence data on adolescent work-related injuries and to determine whether such injuries are underreported to the Minnesota Department of Labor and Industry. METHODS: The study consisted of a 1-year survey of 534 adolescent work-related injuries reported to the Department of Labor and Industry and a cross-sectional survey of 3312 public high school students from throughout Minnesota. The high school survey used an abbreviated questionnaire with a subset of items from the Department of Labor and Industry survey. RESULTS: Ninety-six percent of the injuries were strains and sprains, cuts and lacerations, burns, bruises and contusions, and fractures. There were 11 hospitalizations; 4 were for burns that occurred during work in restaurants. Eighty workers (15%) reported permanent impairment as a result of their injuries. It was estimated that there were 2268 reportable injuries to working adolescents in Minnesota during the study year. CONCLUSIONS: The most common serious injuries were injuries to the lower back and burns. The demographic characteristics of adolescents whose injuries were reported to the Department of Labor and Industry were similar to those of injured adolescent workers identified through the high school survey. The results suggest that there is substantial underreporting of adolescent work injuries.

Incidence, prevalence, and mortality of diabetes mellitus in Wadena, Marshall, and Grand Rapids, Minnesota: the Three-City Study.

The Minnesota Department of Health (MDH) in concert with the Centers for Disease Control (CDC) conducted population-based studies of diabetes mellitus in three Minnesota communities. The use of hospital and clinic records alone for case ascertainment purposes would have missed 16% of study-eligible diabetic individuals. Thus, studies that use only hospital or clinic records may present a biased view of the natural history of diabetes. Physician-defined diabetes without additional diagnostic review yielded a prevalence of 1.6% (age standardized to the 1970 US Caucasian population). Diabetes incidence was 117 per 100,000 (age standardized to the same population). These results compare well with those of a Mayo Clinic population-based study in Rochester, Minnesota, and indicate the utility of physician-defined diabetes as an epidemiologic case definition. Despite differences in population size and structure as well as different medical care systems, diabetes incidence, prevalence, and mortality in these communities was remarkably similar.

The distribution of Mycobacterium avium ssp. paratuberculosis in the environment surrounding Minnesota dairy farms.

The objective of this study was to characterize the distribution of Mycobacterium paratuberculosis (Map) in the environment of infected and uninfected Minnesota dairy farms. Eighty herds known to be infected from Minnesota's Johne's Disease Control Program (JDCP) and 28 herds known to be uninfected from Minnesota Voluntary Johne's Disease Herd Status Program (VJDHSP) were sampled. Fecal samples from up to 100 cows in each herd were cultured in pools of 5 cows. Two environmental samples were obtained from each farm from various locations. All samples were tested using bacterial culture for Map. Eighty percent of the JDCP herds had at least one positive pool. Environmental samples were cultured positive in 78% of the JDCP herds. Two (7%) of the VJDHSP herds had one positive pool, and one herd had one positive environmental sample. Environmental samples were cultured positive in cow alleyways (77% of the herds), manure storage (68%), calving area (21%), sick cow pen (18%), water runoff (6%), and postweaned calves areas (3%). There was an association between maximum level of colonies per tube from cow alleyways and manure storage and fecal pool prevalence. Herds with both areas cultured negative were estimated to have 0.3 to 4% fecal pool prevalence. Herds with both areas having a heavy load of bacteria were estimated to have 53 to 73% fecal pool prevalence. The study results indicate that targeted sampling of cow alleyways and manure storage areas appears to be an alternative strategy for herd screening and Johne's infection status assessment and for estimating herd fecal prevalence.

Volumetric assessment of airborne pollen and spore levels in Rochester, Minnesota, 1992 through 1995.

OBJECTIVE: To reassess airborne pollen counts and to study spore counts by volumetric collection in Rochester, Minnesota. MATERIAL AND METHODS: Samples of pollen and spores were collected from the top of a six-story building in downtown Rochester by use of a rotational rod sampler, which was activated for 30 seconds every 10 minutes for 24 hours a day, 5 days a week, from mid-April to mid-October 1992 through 1995. Particles were stained with Calberla's fluid and viewed microscopically by transmitted light. Identifications were substantiated by comparison with field-collected "known" materials and standard reference guides. Data were expressed as "particles retained/cubic meter of air sampled." RESULTS: Because the methods of collection varied, only qualitative comparisons could be made with a study done in Rochester more than 3 1/2 decades earlier. For tree pollens, a similar progression of appearance and seasonal duration were noted for most species. Alder (Alnus), willow (Salix), and hickory-pecan (Carya), however, were found to have distinctly longer seasons, and walnut (Julgans) was detected 2 weeks earlier in the season. The most frequently detected tree pollen had changed from oak (Quercus) to apple and crab apple (Malus), which was not reported at all previously. Ragweed (Ambrosia) was still found to peak at the end of August and had a similar duration. Study of grass and nettle pollen as well as the Amaranthaceae-Chenopodiaceae complex yielded findings similar to those in the prior investigation. Fungal spores were detected from April through October and represented a substantial percentage of the airborne allergens; Cladosporium, ascospores, and basidiospores were the most common. CONCLUSION: Volumetric assessment of airborne pollen and spore levels in Rochester, Minnesota, yielded useful information for clinicians in southern Minnesota that could help direct skin test selection.
