Delaware RNs' reasons for nonparticipation in continuing education.

A descriptive study determined the reasons for nonparticipation in continuing education (CE) for RNs living in Delaware, where lack of CE results in loss of licensure. Subjects were asked to complete a 40-item Deterrents to Participation Scale with a 13-item demographic questionnaire. The sample (N = 94) identified disengagement as the primary factor for predicting nonparticipation in CE, with the primary reason being they had higher priorities than CE in their lives. Implications for nursing administrators and educators are discussed.

Pullorum disease in Delaware roasters.

An index case of pullorum disease in 4-week-old roasters from a completely integrated poultry operation is reported from Delaware. Severe articular and periarticular swelling of hock and/or wing joints was observed on postmortem examination. Also seen were moderate to severe hydropericardium and large white-gray nodules in the heart and gizzard that grossly could have been taken for tumors. The livers showed multiple small white foci, petechial hemorrhages, and swelling. Initially, Salmonella pullorum was isolated from the articular fluid by direct culture on MacConkey agar, but it was not isolated from liver, spleen, or heart samples after enrichment in selenite broth.

Selected mosquito vectors of West Nile virus: comparison of their ecological dynamics in four woodland and marsh habitats in Delaware.

We compared human landing, CO2-baited light trap, CO2-baited Omni-Fay trap, and gravid trap collections of mosquitoes at 4 woodland and marsh sites with varied vegetative habitats in Delaware during summer 2001. Landing collections provided more consistent, but sometimes smaller, collection numbers than light traps. Proportions of parous mosquitoes were also higher in landing than in light trap or Omni-Fay collections about 65% of the time. Circadian feeding rhythms were observed for 3 suspected vector species selected on the basis of 1999-2000 laboratory vector competence data and their presence at local habitats. These species included Aedes vexans, Culex salinarius, and Cx. pipiens pipiens. Aedes vexans fed after dusk, primarily before 2200 h and again around dawn (0600-0700 h). Both Cx. salinarius and Cx. p. pipiens exhibited peak feeding activity after dusk and in predawn periods, as well as extended feeding periods up until midnight. Time of feeding is an important factor in evaluating vector-host associations and risks of human outbreaks.

Pertussis outbreak in an Amish community--Kent County, Delaware, September 2004-February 2005.

Vaccine-preventable disease outbreaks continue to occur among undervaccinated populations in the United States, including contained religious communities. The Amish practice separation from the world through group solidarity and caring for their own. Amish religious doctrine does not prohibit vaccination; however, coverage levels for routine childhood vaccination remain low in many Amish communities. This report describes an outbreak of pertussis in an Amish community in Kent County, Delaware, during September 2004-February 2005, that resulted in 345 cases and affected primarily preschool-aged children. The outbreak underscores the need to promote vaccination in Amish communities through culturally appropriate strategies, such as education and outreach to community leaders.

Breastfeeding continuation factors in a cohort of Delaware mothers.

PURPOSE: To determine whether maternal age, race, or income, is the primary determinant of breastfeeding continuation rates. METHODS: Using the Delaware modified-PRAMS 2000 de-identified data set, multivariate modeling of age, income, race, weight, health status, and other breastfeeding continuation factors were analyzed. RESULTS: Breastfeeding continuation at 12 weeks of age was predicted by maternal age independent of race or income. Mothers greater than the mean age were 86% more likely to continue to breastfeed than younger mothers (OR 1.861 95% CI 1.234-2.805). Maternal BMI > or = 26, nipple soreness, and breastfeeding difficulty were associated with lower breastfeeding continuation. DISCUSSION: Maternal age, not race or income, are driving factors in breastfeeding continuation. Physiologic variables, such as maternal obesity, breastfeeding difficulty, and nipple soreness have an adverse influence on duration of breastfeeding. Investment into processes that lengthen breastfeeding duration among mothers, especially younger mothers, who chose to initiate breastfeeding, may have individual and community benefits.

Concentrations of total mercury in several fishes from Delaware Bay, 1975.

Mercury levels in eleven species of fishes collected from lower Delaware Bay in April 1975 ranged from 0.018 to 0.321 microgram/g and averaged 0.092 microgram/g. Raja eglanteria, the clearnose skate, had the highest mean mercury concentration (0.214 microgram/g). No correlation was found with feeding habits. These assays provide baseline data for future measurement of mercury accumulation by fishes in this region.

The impact of consumer health information provided by libraries: the Delaware experience.

In the past two decades, consumer health libraries have proliferated in response to the changing health care environment and consumer demand. While this growth of consumer health resources and services has been extensively described in the literature, there is little documentation about the impact and value of providing consumer health information. This paper explores the issues of impact and value as examined in a retrospective study of consumers who received health information from the Delaware Academy of Medicine's Consumer Health Library during 1995. In this study, 270 adults were mailed a questionnaire that focused on whether the information influenced decisions, actions, anxiety levels, and patient-provider communication. The questionnaire also addressed the value of such library service in terms of likelihood of repeat use, recommendation to others, and willingness to pay. The results, based on a return rate of 86.7%, identified effects of library-supplied consumer health information that extend beyond the anticipated acquisition of knowledge to specific actions and effects on anxiety. The value of consumer health library information service was shown by the extremely high percentage of probable repeat use and recommendation to others, the willingness of 83.8% of the respondents to pay for such service, and the copious comments volunteered by the respondents.

Antigenic and S-1 genomic characterization of the Delaware variant serotype of infectious bronchitis virus.

A previously unrecognized infectious bronchitis virus (IBV) serotype, referred to hereafter as the Delaware variant (DE var), was isolated from commercial broiler chickens during a severe, widespread respiratory disease epornitic in the Delmarva peninsula region of the United States in January-March 1992. The DE var serotype was found to be antigenically unrelated by virus-neutralization (VN) test to nine reference IBV serotypes from North America. Additional VN tests indicated that the DE var isolates (DE/072/92, DE/121/ 92, DE/152/92, and DE/174/92) from broilers were fully or partially neutralized by monospecific antisera prepared against themselves and against two IBV field isolates (DE/492/90 and DE/903/90) recovered from a Delmarva commercial layer flock experiencing egg production losses in 1990. Antigenic relatedness values determined by VN indicated layer isolate DE/492/90 was more closely related to the broiler DE var isolates than was layer isolate DE/903/90. Cross-challenge tests performed in specific-pathogen-free chickens also demonstrated the antigenic similarity of the broiler (DE/072/92 and DE/174/92) and the layer isolates (DE/492/90 and DE/903/90), with heterologous strain protection values ranging from 55% to 100%. Protection values of DE var isolates vs. Massachusetts 41 and Arkansas DPI were considerably lower (0-60%). The S-1 gene of the US/DE/072/92 isolate of the DE var serotype was amplified by reverse transcription polymerase chain reaction, cloned, and sequenced. The DE var S-1 gene sequence was compared with the S-1 gene sequences of IBV serotypes from North America, Europe, and Australia. A dendrogram based on this analysis supported the conclusion that the DE var serotype is highly novel among IBV. A high degree of similarity (> 88%) was observed between the S-1 genes of the DE var broiler isolates (DE/072/92 and DE/174/92) and layer isolates (DE/492/90 and DE/903/90). These data, taken with the VN and cross-challenge results, establish a genetic as well as an antigenic link between the isolates from layers and broilers and indicate the DE var serotype was responsible for both infectious bronchitis outbreaks.

Ilyanassa obsoleta (Gastropoda) as a host for trematodes in Delaware estuaries.

Extensive data characterizing larval trematode communities in marine gastropods do not exist for many systems. The purpose here is to report on the infections encountered in Delaware Ilyanassa obsoleta and to compare this trematode community with certain others that have been well studied. Over 15 yr, 11,774 I. obsoleta from 9 different estuarine habitats were examined. Trematode parasitism, sex, and size were determined for each snail. In the total collection, 9 trematode species were encountered; 51.04% of snails were infected with 1 or more species. The sexes were equally susceptible to being parasitized. Smaller snails were less likely to be infected than larger ones. Juvenile snails can be infected, but few have been colonized because of the short time they have been exposed to infective stages. Other studies of trematodes in this snail have revealed few multispecies infections. In contrast, they were strikingly common in this study (12.57% of all snails). Himasthla quissetensis seldom infects the same snail with Lepocreadium setiferoides or Austrobilharzia variglandis, but other species combinations can coexist. The important element in this trematode community seems to be time. The observed frequencies of different infracommunities (single and multispecies combinations) in samples of snails are considered to result from a variety of causes. These include commonness of the trematode species in the system, where and how the sample was collected, definitive host behavior, the low probability of a snail becoming infected, the long life of the snail and its infections, the vagility of the snail, and the incompatibility of certain species in terms of infecting the same snail.

A comparison of congeneric PCB patterns in American eels and striped bass from the Hudson and Delaware River estuaries.

The Hudson River estuary has enormous spatial variation in polychlorinated biphenyl (PCB) contamination due in large part to historical point source discharges above Troy Dam. The Delaware River estuary has accumulated significant levels of PCBs through decades of industrial, municipal, and non-point source inputs. The overall goal of this research was to use existing data sets to compare and contrast the patterns of accumulated PCB congeners in sub-populations of American eels and striped bass inhabiting these two estuaries and surrounding coastal waters. Using principal component analysis and analysis of covariance (ANCOVA), inter- and intra-estuarine differences in accumulated congeneric patterns were denoted for both species. Results from our study support the idea that migratory behaviors of striped bass hamper the use of accumulated congener-specific PCB patterns in providing information on localized contamination, although major regional differences were seen between upriver Hudson River fish, downriver Hudson River fish and fish from other areas within this study. This study provides additional evidence for the use of the American eel as a biomonitoring tool, since its limited home range provides finer resolution of regional contamination.

Effects of naphthalene on microbial community composition in the Delaware estuary.

The effects of naphthalene on microbial communities in the bottom boundary layer of the Delaware Bay estuary were investigated in microcosms using denaturing gradient gel electrophoresis (DGGE) and fluorescent in situ hybridization (FISH) with oligonucleotide probes. Three days after the addition of naphthalene, rates of bacterial production and naphthalene mineralization were higher than in no-addition controls and than in cases where glucose was added. Analyses using both DGGE and FISH indicated that the bacterial community changed in response to the addition of naphthalene. FISH data indicated that a few major phylogenetic groups increased in response to the glucose addition and especially to the naphthalene addition. DGGE also demonstrated differences in community composition among treatments, with four phylotypes being unique to naphthalene-amended treatments and three of these having 16S rRNA genes similar to known hydrocarbon degraders. The bacterial community in the naphthalene-amended treatment was distinct from the communities in the glucose-amended treatment and in the no-addition control. These data suggest that polycyclic aromatic hydrocarbons may have large effects on microbial community structure in estuaries and probably on microbially mediated biogeochemical processes.

Enumeration and relative importance of acetylene-reducing (nitrogen-fixing) bacteria in a delaware salt marsh.

Three groups of N(2)-fixing bacteria were enumerated from the top 1 cm of the surface in four vegetational areas in a Delaware salt marsh. The results over the 9-month sampling period showed that there were no discernible seasonal patterns for any of the groups enumerated (Azotobacter sp., Clostridium sp., and Desulfovibrio sp.). Azotobacter sp. was present in numbers of 10 per g of dry mud, whereas the two anaerobic fixers were present in much lower numbers (10 to 10 per g of dry mud). There were no differences in the numbers of each group among the different vegetational areas, indicating that there was a heterogeneous population of N(2) fixers present. Additional studies indicate that the activity of sulfate reducers (Desulfovibrio sp.) may account for as much as 50% of the total observed acetylene reduction activity. Oxygen was found to exert little effect on the observed acetylene reduction activity, indicating that stable aerobic and anaerobic microenvironments exist in the surface layer of marsh sediments.

Neural network modelling of Cryptosporidium and Giardia concentrations in the Delaware River, USA.

Artificial neural networks are brain-like structures used in mathematical modelling that excel in pattern recognition. In this research, a simple feed-forward artificial neural network, trained by error back-propagation algorithm, was used as a tool to relate peak Cryptosporidium and Giardia concentrations with other biological, chemical and physical parameters in surface water. Multiple water quality parameters at a water treatment plant intake on the Delaware River, New Jersey, USA, collected in 1996, were provided to the authors for recognition analysis. Water samples were classified as "background" and "above background" based on the concentration of full and empty oocysts and cysts of Cryptosporidium and Giardia. The results of this preliminary effort were encouraging. Parameters significant to the identification of each protozoa were identified, eight for Cryptosporidium and seven for Giardia by a stepwise elimination technique. Data withheld from the model training was used to validate the trained models and evaluate the most effective internal architecture. In both cases, the best prediction performance was found when the number of internal nodes was twice that of the input parameters in single hidden-layer architecture. Predictions for the classification of the verification data set resulted in no false-negatives (mis-prediction of above background protozoa concentrations) when the models were optimally trained.

Residues of organochlorines and heavy metals in ruddy ducks from the Delaware River, 1973.

In December 1973, eight ruddy ducks killed in an oil spill on the Delaware River were collected to be analyzed for residues of environmental pollutants. Whole carcasses were analyzed for organochlorine pesticides and livers were examined for lead, cadmium, and mercury. Residues of polychlorinated biphenyls and DDT and/or its metabolites were present in all carcasses. Dieldrin and hexachlorobenzene were present in seven of the eight samples. All livers contained detectable levels of lead, cadmium, and mercury.
