Effects of breed group by location interaction on crossbred cattle in Nebraska and Florida.

Data on 2,744 calves produced in Clay Center, Nebraska and Brooksville, Florida were used to evaluate the importance of genotype x location interactions on the reproductive and maternal performance of eight breed groups of F1 crossbred cows. A total of 648 F1 crossbred cows included Bos taurus x Bos taurus (Bt x Bt) crosses: Hereford x Angus reciprocal crossbreds (HA and AH), Pinzgauer x Angus (PA), Pinzgauer x Hereford (PH); and Bos indicus x Bos taurus (Bi x Bt) crosses: Brahman x Angus (BA), Brahman x Hereford (BH), Sahiwal x Angus (SA) and Sahiwal x Hereford (SH). The first calf crop was sired by Red Poll bulls. All remaining calf crops were sired by Simmental bulls. Although the pregnancy rate was 9% higher in Nebraska, the rate of unassisted calvings and calf survival rate were both 4.6% lower in Nebraska. Calf birth and weaning weights were 8.0 and 15.6 kg heavier in Nebraska than in Florida. Bi x Bt dams exceeded (P less than .001) Bt x Bt crossbred dams for all traits except age of calf at weaning and calf-survival rates (P greater than .10). Birth weights of calves from Bi x Bt crossbred dams were 3.4 kg lighter than those from the Bt x Bt crossbred dams. The interaction of location with the breed group comparison of Bi x Bt vs Bt x Bt crossbred dams was significant for pregnancy rate, calf age at weaning, rate of unassisted calving and all weight traits. Adjusted weaning weights of calves from HA, AH, PA, PH, BA, BH, SA and SH cows were as follows: HA, 194 and 222; AH, 202 and 230; PA, 213 and 242; PH, 217 and 245; BA, 251 and 254; BH, 252 and 254; SA, 236 and 238; and SH, 238 and 243 kg, respectively, in Florida and Nebraska. Bos indicus-sired cows (BA, BH, SA and SH) weaned essentially equal-weight calves at both locations, whereas calves from Bt x Bt crossbred cows (HA, AH, PA, PH) were about 28 kg lighter in Florida.

Survey of Florida green turtles for exposure to a disease-associated herpesvirus.

A recently developed enzyme-linked immunosorbent assay (ELISA) was used to assess exposure of Florida wild green turtles Chelonia mydas to LETV, the herpesvirus associated with lung-eye-trachea disease (LETD). Plasma samples from 329 wild juvenile green turtles netted in the Indian River lagoon, along the Sebastian reef, or in the Trident basin (Indian River and Brevard Counties, Florida) were tested by ELISA for the presence of antibodies to LETV. Plasma samples from 180 wild juvenile green turtles were tested from these study sites to compare the prevalence of anti-LETV antibodies. While some plasma samples from each site contained anti-LETV antibodies (confirmed by Western blot analysis), plasma samples collected from the Indian River lagoon had statistically higher optical density values measured in the ELISA. No statistical differences were observed when these same plasma samples were analyzed for changes in the level of anti-LETV antibodies over 3 years (1997, 1998, and 1999). To explore the relationship between anti-LETV antibodies and fibropapillomatosis (FP), plasma from 133 green turtles scored for fibropapilloma tumor severity were tested by ELISA. There was no correlation between tumor severity and the presence of antibodies against LETV. Additional plasma samples collected from 16 tagged green turtles captured and sampled more than once (recaptures) were also tested to monitor antibody levels to LETV relative to the FP status of individual turtles over time. Again there was no clear relationship between FP tumor status and the presence of antibodies to LETV. Finally, ELISA tests on plasma from 13 nesting female turtles (9 green and 4 loggerhead) revealed high levels of anti-LETV antibodies in 11 individuals, including 2 loggerhead turtles. These results provide strong evidence that wild Florida green turtle populations at these 3 study sites are exposed to LETV or a closely related virus and that loggerhead turtles may be exposed as well. Based on a cutoff optical density value of 0.310, 71 out of the 329 wild Florida green turtles tested were seropositive for LETV antibodies (seroprevalence = 21.6%). In addition, no relationship between FP tumor severity or status and the presence of anti-LETV antibodies was found, further supporting the hypothesis that LETV and the FP-associated herpesvirus (FPHV) are separate infections of marine turtles.

Incentives and physician specialty choice: a case study of Florida's Program in Medical Sciences.

The growing shortage of primary care physicians in medically underserved areas of the nation led medical schools and policymakers years ago to design and fund numerous innovative medical education programs to foster the development of a more balanced physician workforce. Florida's Program in Medical Sciences (PIMS) was an example of one such initiative that was established in fall 1971 at Florida State University (FSU). A precursor of the present-day FSU College of Medicine, this program was created specifically to address the growing need for primary care physicians in rural areas of northwest Florida. The results of empirical tests on the career choices of PIMS graduates in the first 20 years provide weak evidence that the program was more effective than the existing channels of medical education in producing additional primary care physicians to rural Florida counties.

Hematologic and serum biochemical reference intervals for Florida panthers.

Ninety-four blood samples were collected from 48 (29 males and 19 females) free-ranging Florida panthers (Felis concolor coryi) captured in southern Florida (USA) from 1983 to 1994 for routine hematological and serum biochemical analysis. Florida panthers in the northern portion of their range had significantly higher red blood cell (mean +/- SD = 7.923 x 10(6) +/- 0.854 x 10(6)/microliter), hemoglobin (12.53 +/- 1.66 g/dl), and packed cell volume (36.97 +/- 4.27%) values compared to those of panthers localized in more southern parts of Florida (7.148 x 10(6) +/- 1.045 x 10(6)/microliter, 11.60 +/- 1.62 g/dl, and 34.82 +/- 5.99%, respectively). Adults had significantly higher mean serum total protein (7.50 +/- 0.59 g/dl) and packed cell volume (36.90 +/- 4.97%) values than juveniles (6.88 +/- 0.49 g/dl and 34.54 +/- 5.30%). However, mean serum albumin concentrations were significantly higher in juveniles (3.80 +/- 0.26 g/dl) when compared to adult values (3.58 +/- 0.26 g/dl). Mean serum calcium concentrations were significantly higher in juveniles (10.33 +/- 0.39 mg/dl) than in adults (9.66 +/- 0.45 mg/dl). Additionally, mean serum iron concentrations were significantly higher in those panthers of intergrade genetic stock compared to values in those of authentic genetic stock (105.6 +/- 72.1 micrograms/dl versus 59.3 +/- 19.7 micrograms/dl, respectively).

Causes of mortality of free-ranging Florida panthers.

The Florida panther (Puma concolor coryi) is one of the most endangered mammals, with the entire population estimated to consist of only 30-50 adult animals. Between 1978 and 1999, 73 free-ranging Florida panther carcasses were submitted for postmortem evaluation, of which 47 (64%) were radiocollared and 26 (36%) were uncollared cats. Overall, mortality of panthers > 6-mo-old was due to vehicular trauma in 25 (35%), intraspecific aggression in 19 (26%), illegal kill in seven (10%), research activities in two (3%), infectious diseases in two (3%), esophageal tear in one (1%), pleuritis in one (1%), pyothorax in one (1%), aortic aneurysm in one (1%), atrial septal defect in one (1%), and causes of death were undetermined in 13 (18%) due to autolysis. Of the 25 panthers that were killed by vehicular trauma, 20 (80%) died between October and April. This coincides with increased number of winter visitors to south Florida. Among radiocollared panthers, intraspecific aggression was the primary cause of mortality for 19 (41%) dead cats. Of these cats, 16 (84%) were males and 14 (88%) were either less than 3 or more than 8-yr-old. These animals were probably fighting to establish or retain territory. Among the 26 uncollared panthers, vehicular trauma was the primary cause of mortality and was responsible for 16 (62%) deaths. This study documents the causes of mortality and the age, sex, and seasonal mortality trends for both radiocollared and uncollared free-ranging endangered Florida panthers over a 21-yr-period.

Gastrointestinal helminths of free-ranging Florida panthers (Puma concolor coryi) and the efficacy of the current anthelmintic treatment protocol.

Thirty-five Florida panthers (Puma concolor coryi [Bangs, 1899]) collected from six counties in southern Florida between 1978 and 2003 were examined at necropsy for gastrointestinal helminths. The panthers were placed into two groups: 1) treated with anthelmintics (n = 17), and 2) untreated (n = 18). Nine species of helminths (one trematode, six nematodes, and two cestodes) were identified in the untreated panthers. The most prevalent helminths were Alaria marcianae (LaRue, 1917) (100%), Spirometra mansonoides (Mueller, 1935) (91%), and Ancylostoma pluridentatum (Alessandrini, 1905) (89%). Ancylostoma caninum (Ercolani, 1859) is reported from the Florida panther for the first time. The intensities of helminths with prevalences >10% did not differ between untreated panthers collected in 1978-1983 and 1996-2003. Treated panthers had helminth faunas similar to those of untreated panthers. The current anthelmintic treatment being used reduced the intensity of both A. marcianae and A. pluridentatum in panthers < or =6 mo posttreatment (PT); however, treated panthers between 6 and 9 mo PT, and >9 mo PT were similar to untreated panthers. Treatment was less effective on S. mansonoides and Taenia omissa Lühe, 1910. Treated panthers had slightly lower intensities of S. mansonoides at < or =6 mo PT; however, between 6 and 9 mo PT and >9 mo PT they had significantly higher intensities than untreated panthers. At all periods PT, the intensity of T. omissa for the treated panthers was similar to that of untreated panthers. We suggest that Mesocestoides sp. may not be present in the Florida panther population as reported earlier by Forrester et al. (1985), due to parasite misidentification by those authors.

Theft of expensive hospital medical equipment: how professional thieves have been operating in Florida; what you should be doing to protect your hospital's assets.

A number of Florida hospitals report they have fallen prey to thieves who are dressing as hospital workers or service company employees and stealing expensive medical equipment. The thefts are creating both financial loss to hospitals and the danger that some lifesaving equipment will be missing when needed. More than 50 hospitals have been hit over the past 18 months, says Jim Kendig, incoming president of the Florida Society for Healthcare Security and Safety Professionals, Orlando. Are these thefts the tip of the iceberg? Logic dictates they are taking place or will take place elsewhere, since there is nothing different security-wise or equipment-wise about Florida hospitals compared to those in the rest of the country that would limit criminals to one state. Therefore, the lessons learned by Florida hospitals, as detailed in this report, are worth heeding elsewhere.

Benefits of political activism: sunset revision of the Florida Medical Practice Act.

Physician assistants need to recognize their ability to influence state legislators, to vigilantly review all legislation affecting the PA profession, and to lobby lawmakers whenever possible. Recent experience in Florida provides a good example of how PAs can effect change. The author retraces legislative and regulatory history of the PA profession in Florida, explaining why change in the Medical Practice Act was needed and how Florida's PAs took advantage of this political opportunity. Legislative response to the recommendations made by the Florida Academy of Physician Assistants is discussed, exploring effectiveness of the FAPA's strategy and providing a model for other states faced with similar legislative battles.

Florida's salt-marsh management issues: 1991-98.

During the 1990s, Florida has continued to make important strides in managing salt marshes for both mosquito control and natural resource enhancement. The political mechanism for this progress continues to be interagency cooperation through the Florida Coordinating Council on Mosquito Control and its Subcommittee on Managed Marshes (SOMM). Continuing management experience and research has helped refine the most environmentally acceptable source reduction methods, which typically are Rotational Impoundment Management or Open Marsh Water Management. The development of regional marsh management plans for salt marshes within the Indian River Lagoon by the SOMM has helped direct the implementation of the best management practices for these marshes. Controversy occasionally occurs concerning what management technique is most appropriate for individual marshes. The most common disagreement is over the benefits of maintaining an impoundment in an "open" vs. "closed" condition, with the "closed" condition, allowing for summer mosquito control flooding or winter waterfowl management. New federal initiatives influencing salt-marsh management have included the Indian River Lagoon-National Estuary Program and the Pesticide Environmental Stewardship Program. A new Florida initiative is the Florida Department of Environmental Protection's Eco-system Management Program with continuing involvement by the Surface Water Improvement and Management program. A developing mitigation banking program has the potential to benefit marsh management but mosquito control interests may suffer if not handled properly. Larvicides remain as an important salt-marsh integrated pest management tool with the greatest acreage being treated with temephos, followed by Bacillus thuringiensis israelensis and methoprene. However, over the past 14 years, use of biorational larvicides has increased greatly.

Comparison of Florida Hispanic and non-Hispanic Caucasian women in their health beliefs related to breast cancer and health locus of control.

PURPOSE/OBJECTIVES: To compare Florida Hispanic and non-Hispanic Caucasian women in their health beliefs about breast cancer and health locus of control (LOC). DESIGN: Exploratory, comparative. SETTING: A variety of healthcare settings in an urban area in Florida. SAMPLE: Hispanic (n = 113) and non-Hispanic (n = 197) Caucasian women who could read and understand either English or Spanish. METHODS: The Health Screening Questionnaire, which assesses health beliefs and health LOC, was administered in either Spanish or English, and the results were analyzed. MAIN RESEARCH VARIABLES: Attitudes about health in general, perceptions about susceptibility to cancer, beliefs about benefits of early diagnosis, and perceptions about the seriousness of cancer; LOC. FINDINGS: Florida Hispanic women are better educated than the Mexican American Hispanic women described in the literature. Hispanic and non-Hispanic women were significantly different in their health beliefs and LOC. With age and education controlled statistically, these differences remained. Hispanic women who preferred to speak/read English were more like the non-Hispanic women in their responses than were the women who preferred Spanish. CONCLUSIONS: Cultural differences exist between Hispanic and non-Hispanic women; however, differences also exist between groups of Hispanic women in Florida versus Hispanics in the southwestern United States. IMPLICATIONS FOR NURSING PRACTICE: Outreach programs for cancer screening should be culturally relevant and may need to be different for subgroups of Hispanics in the United States.

Cancer trends among Hispanic men in South Florida, 1981-1998.

BACKGROUND: Hispanics now represent a majority of residents in Miami-Dade County, Florida. In this report, the authors present new cancer incidence and mortality data for South Florida's Hispanic men for the period 1990-1998 and compare them with data from a previous report from the 1980s. Periodic updating of cancer incidence data, reflecting current population distribution, lifestyle, and environmental risk factors, is necessary to inform cancer prevention and control activities optimally. METHODS: The study population consisted of all incidents of cancer (1981-1998) occurring in males from Miami-Dade County, as determined from the Florida Cancer Data System data base; patients were divided into two 9-year periods for analysis. Age-standardized incidence and mortality rates were computed for 14 common cancer sites, and rates for Hispanic men were compared with the rates for non-Hispanic white men as standardized rate ratios (SRRs) with 95% confidence intervals (95% CIs). Incidence and mortality trends were determined using linear regression analysis. RESULTS: Nearly 70,000 incident cancer cases were analyzed. For 1990-1998, the top five incident cancers for both race/ethnic groups were the same. The overall decreased cancer risk for Hispanic men (SRR, 0.80; 95% CI, 0.79-0.82), compared with non-Hispanic white men, remained essentially constant over the two study periods. Cancer incidence increased similarly for the two race-ethnic groups; cancer mortality decreased, with a sharper decrease for non-Hispanic white men, resulting in apparent convergence of mortality trends recently. CONCLUSIONS: Differences in cancer risk for South Florida's Hispanic men have not attenuated over the past 20 years. With cancer incidence significantly less for Hispanic men, their mortality rate approaches that of non-Hispanic white men, and cancer prevention and control strategies targeted for this ethnic group become increasingly important.

Occurrence of chlorinated hydrocarbon insecticides, southern Florida--1968-72.

The frequency with which chlorinated hydrocarbon insecticides appear in samples of southern Florida surface waters decreased sharply between 1968 and 1972. Sediment analyses attest to the earlier widespread use of chlordane, DDT, and dieldrin. Insecticide residues are more frequently detected in southern Florida than in other U.S. cropland soils. Transport of DDT, DDD, and DDE from the Everglades agricultural area into water conservation areas and undeveloped parts of the Everglades of southeastern Florida is facilitated by a system of water-management canals. Canal sediments within the urban area of southern Florida have high DDD, DDE, and dieldrin residue concentrations which may reflect local use of insecticides rather than their transport from adjacent agricultural areas.

The black cloud over the Sunshine State: health disparities in south Florida.

Florida, the "Sunshine State", is paradise for international tourists and has been adopted as seasonal or permanent home by many wealthy individuals and celebrities. However, Florida is not paradise for the growing number of residents who suffer from poverty, health problems, and a lack of access to health care and social services. The purpose of this paper is to present data on health care problems and disparities throughout the state of Florida and in select south Florida counties. Flaskerud and Winslow (1998) have provided a framework which can be used to analyze disparities in resource availability, relative risk, and health status indicators and suggests areas in which nursing and other health professionals can ethically intervene through research, practice, and political action.

Improving performance on the endodontic section of the Florida Dental Licensure Examination.

In an attempt to improve performance of University of Florida College of Dentistry (UFCD) graduates on the endodontic section of the Florida Dental Licensure Examination, a retrospective analysis was conducted for classes graduating between 1996 and 2003 to assess potential relationships between passing and failing performance and three factors with potential impact on "first attempt" pass rates. The three factors were clinical endodontic experience, performance on the senior mock board examination, and dialogue with representatives of the licensure examination, which resulted in modification of the endodontic section of the licensure exam. Using ANOVA, we found no differences in performance on the endodontic section of the senior mock board exam between graduates who passed the endodontic section of the dental licensure exam and those who failed this section. Furthermore, no differences were found in the mean number of clinical endodontic experiences (number of teeth treated) between graduates who passed the endodontic section of the licensure exam and those who failed. However, in 2003 following dialogue between representatives of the Florida Board of Dentistry and endodontic faculty from the two dental schools in Florida, a significant difference in senior mock board endodontic scores (p>0.05) and a significant difference in performance on the endodontic section of the licensure exam scores (p>0.005) was observed for the 2003 graduates when compared to the 2002 graduates. The mean mock board scores and the mean state board endodontic section scores were higher for the 2003 graduates. In addition, the UFCD failure rate on the endodontic section of the state board exam dropped from 34 percent in 2002 to 6 percent in 2003. The primary factors believed responsible for these improvements were a direct result of dialogue between dental school faculty and state board representatives. They include a greater appreciation by the UFCD faculty for the performance criteria used by the Board of Dentistry to evaluate procedures and a change by the board in the tooth selection criteria for the endodontic experience. The options in tooth-type used in the board exams increased from a two-rooted maxillary premolar to any anterior or premolar tooth. In conclusion, this report supports the positive benefits from ongoing discussions between dental school faculty and representatives of the state licensure board.

Tuberculosis among foreign-born children in the State of Florida, 1993--1999: a re-emergence phase after a sustained decline?

STUDY OBJECTIVE: To determine the temporal trend of tuberculosis disease among foreign-born children in the State of Florida. DESIGN AND SETTING: Descriptive population-based study on data obtained from the Tuberculosis Control and Surveillance Program in the State of Florida. We employed Poisson assumption to derive estimates for rates of tuberculosis among US-born and foreign-born children in the studied population. We also applied linear and nonlinear regression equations to describe the best trajectories for observed temporal trends in incidence cases of the disease. PATIENTS: All cases of tuberculosis disease among children notified in the State of Florida between 1993 and 1999 inclusive. MAIN RESULTS: The incidence rate of TB over the study period was five times higher among foreign-born children (11.3 per 105; CI = 8.0-14.6 per 105) as compared to US-born (1.7 per 105; CI = 0.8-4.2 per 105). Whereas, new cases of TB among US-born children have continuously and significantly dropped throughout the period of study, our data indicated that the decline achieved from 1993 to 1996 among foreign-born children has ceased, and a resurgence of tuberculosis in this population was apparent. CONCLUSIONS: Our data tend to suggest a re-emergence of tuberculosis among foreign-born children in the State of Florida as from 1997 after several years of decline. There is a need for a more in-depth investigation to elucidate and address causes responsible for the resurgence if the current battle to eliminate tuberculosis from the State is to succeed.

Gonococcal infection of the newborn in Florida, 1984-1989.

An increase in neonatal gonococcal infections was recorded in Florida between 1984 and 1988. By reviewing Florida sexually transmitted disease surveillance case records between 1984 and 1989, 68 cases of neonatal gonococcal infections were identified state-wide. Those 68 cases included 55 (81%) cases of gonococcal ophthalmia neonatorum, 4 genital infections, 1 nasal infection, 1 ear infection, 1 skin infection, and 1 scalp infection. At birth, positive culture results were demonstrated in 3 gastric and 2 respiratory aspirate cultures. A case-control study using birth certificates as the source of information showed that mothers of infected infants were more likely to be younger, black (odds ratio [OR] = 6.2; 95% confidence interval [CI] 2.3, 16.2), and less educated (less than a high school education, OR = 2.9, CI 1.0,8.8) in comparison to mothers of control subjects. Although mothers of infected newborns were less likely to have received prenatal care than were mothers of control subjects, this difference was not statistically significant. Maternal substance abuse was documented among 19% of the mothers of the infected infants. The rate of clinical gonococcal ophthalmia neonatorum in Florida hospitals from which cases had been reported was 1.7 per 10,000 live births, and tended to be higher in hospitals using erythromycin than in hospitals using any other prophylactic eye treatment. This study suggests that the rate of neonatal gonococcal infection, in particular ophthalmia neonatorum, may have increased in Florida among high-risk populations between 1984 and 1988, and underscores the need for targeted prevention efforts and surveillance.

Epidemiologic assessment of the impact of four hurricanes--Florida, 2004.

During August 13, 2004-September 25, 2004, Florida experienced four major hurricanes: Charley and Frances (both Category 4) and Ivan and Jeanne (both Category 3). An estimated 20% of homes throughout Florida were damaged by these hurricanes, and 124 persons died. In October 2004, the Florida Department of Health (FDOH) added 30 questions to the Behavioral Risk Factor Surveillance System (BRFSS) survey to assess the impact of the hurricanes on state residents. This report summarizes the results of that survey, which indicated that 48.7% of Florida residents had no evacuation plan before any of the hurricanes, portable generators were used in 17.5% of homes after electric power outages, and residents of counties not in the direct paths of the four hurricanes had consequences similar to those who lived in the direct paths of the hurricanes (e.g., physical injuries, barriers to medical treatment, and loss of work days). Public health officials should consider the needs of residents both in and not in the direct paths of hurricanes in their preparedness planning.
