Antimicrobial resistance of animal and human strains of Enterobacteriaceae in Greece.

Two hundred sixty two strains of Enterobacteriaceae from animal and human sources where intermixing and/or spreading is possible were examined for their resistance to 15 antimicrobials frequently used in animal prophylaxis and metaphylaxis. The antimicrobials with the highest proportion of resistant strains from animal sources were amoxicillin 25 mg, colistin sulphate 25 mg, erythromycin 5 mg, penicillin G 10 mg and spectinomycin 10 mg. The same with isolates from human sources where ampicillin 10 mg, amoxicillin 25 mg, colistin sulphate 25 mg, erythromycin 5 mg, neomycin 10 mg, penicillin G 10 mg and spectinomycin 10 mg. Human isolates were resistant to more antimicrobials than animal isolates. Common a high proportion of isolates from both sources were resistant to some antimicrobials. Systematic and better distributed information is needed to address the epidemiological role of veterinary treatment, prophylaxis and metaphylaxis in antimicrobial resistance in Greece.

Distribution of deoxynivalenol in wheat, wheat flour, bran, and gluten, and variability associated with the test procedure.

Analytical data obtained on deoxynivalenol (DON) concentration in naturally contaminated wheat during processing in an industrial mill were statistically analyzed, and the distribution functions of DON concentration in lots of wheat, bran, wheat flour, and gluten were estimated. The analytical method had acceptable precision (HORRAT 0.25-0.32) for each test sample. The total variance combined sampling, sample preparation, and analytical variances were 0.188, 0.033, 0.42, and 0.0014 ppm2 for wheat, 1.93; flour, 0.99; bran, 4.68; and gluten, 0.29, respectively. The distribution function of DON contamination presented an asymmetric tail for high values of concentration in wheat grains and wheat flour; in bran it seemed to be bimodal with 2 separated peaks of different concentrations; in gluten the normal distribution function gave a reasonably good fit to empirical data. The function eta(c) = -In(-Inp), where p (c) is the cumulative distribution function was linear with c in the so-called extreme-value type I distribution and could be fitted by a cubic polynomial in c in the distributions determined for all the products. This variability and distributional information contributes to the design of better sampling plans in order to reduce the total variability and to estimate errors in the evaluation of DON concentration in lots of wheat and wheat products.

A new species of Lipoptena (Diptera:Hippoboscidae) from southern Africa.

A new species of Lipoptena Nitzsch, 1818 was found on springbok Antidorcas marsupialis Zimmerman, 1780 in the Cape Province and the Orange Free State, South Africa. The flies, for which the name Lipoptena annalizeae is proposed, can be differentiated from the closely related Lipoptena sepiacea Speiser, 1905 on size, palps, chaetotaxy, pulvilli, and the shape of the posterior genital plates of the males. The morphology of the puparium of the new species is also described and compared with that of the puparia of Lipoptena paradoxa Newstead, 1907 and Lipoptena binocula (Speiser, 1908). A revised key to the southern African species and a summary of host records and distributional information is also presented.

Who's enrolled in the State Children's Health Insurance Program (SCHIP)? An overview of findings from the Child Health Insurance Research Initiative (CHIRI).

BACKGROUND: The State Children's Health Insurance Program (SCHIP) was enacted in 1997 to provide health insurance coverage to uninsured low-income children from families who earned too much to be eligible for Medicaid. OBJECTIVES: To develop a "baseline" portrait of SCHIP enrollees in 5 states (Alabama, Florida, Kansas, Indiana, and New York) by examining: 1) SCHIP enrollees' demographic characteristics and health care experiences before enrolling in SCHIP, particularly children with special health care needs (CSHCN), racial and ethnic minority children, and adolescents; 2) the quality of the care adolescents received before enrollment; and 3) the changes in enrollee characteristics as programs evolve and mature. METHODS: Each of 5 projects from the Child Health Insurance Research Initiative (CHIRI) surveyed new SCHIP enrollees as identified by state enrollment data. CHIRI investigators developed the CHIRI common core (a set of survey items from validated instruments), which were largely incorporated into each survey. Bivariate and multivariate analyses were conducted to ascertain whether there were racial and ethnic disparities in access to health care and differences between CSHCN and those without. Current Population Survey data for New York State were used to identify secular trends in enrollee characteristics. RESULTS: Most SCHIP enrollees (65% in Florida to 79% in New York) resided in families with incomes < or =150% of the federal poverty level. Almost half of SCHIP enrollees lived in single-parent households. A majority of SCHIP parents had not had education beyond high school, and in 2 states (Alabama and New York) approximately 25% had not completed high school. The vast majority of children lived in households with a working adult, and in a substantial proportion of households both parents worked. Children tended to be either insured for the entire 12 months or uninsured the entire 12 months before enrolling in SCHIP. Private insurance was the predominant form of insurance before enrollment in SCHIP in most states, but 23.3% to 51.2% of insured children had Medicaid as their most recent insurance. HEALTH CARE USE AND UNMET NEEDS BEFORE SCHIP: The vast majority of all SCHIP enrollees had a usual source of care (USC) during the year before SCHIP. The proportion of children who changed their USC after enrolling in SCHIP ranged from 29% to 41.3%. A large proportion of SCHIP enrollees used health services during the year before SCHIP, with some variability across states in the use of health care. Nevertheless, 32% to almost 50% of children reported unmet needs. CSHCN: The prevalence of CSHCN in SCHIP (between 17% and 25%) in the study states was higher than the prevalence of CSHCN reported in the general population in those states. In many respects, CSHCN were similar to children without special health care needs, but CSHCN had poorer health status, were more likely to have had unmet needs, and were more likely to use the emergency department, mental health care, specialty care, and acute care in the year before enrolling in SCHIP than children without special health care needs. RACE AND ETHNICITY: A substantial proportion of SCHIP enrollees were black non-Hispanic or Hispanic children (Alabama: 34% and <1%; Florida: 6% and 26%; Kansas: 12% and 15%; and New York: 31% and 45%, respectively). Minority children were poorer, in poorer health, and less likely to have had a USC or private insurance before enrolling in SCHIP. The prevalence and magnitude of the disparities varied among the states. QUALITY OF CARE FOR ADOLESCENTS: Seventy-three percent of adolescent SCHIP enrollees engaged in one or more risk behaviors (ie, feeling sad or blue; alcohol, tobacco, and drug use; having sexual intercourse; and not wearing seat belts). Although almost 70% of adolescents reported having had a preventive care visit the previous year, a majority of them did not receive counseling in each of 4 counseling areas. Controlling for other factors, having a private, confidential visit with the physician was associated with an increased liked likelihood (2-3 times more likely) that the adolescent received counseling for 3 of 4 counseling areas. TRENDS OVER TIME: New York SCHIP enrollees in 2001, compared with 1994 enrollees in New York's SCHIP-precursor child health insurance program, were more likely to be black or Hispanic, older, from New York City, and from families with lower education, income, and employment levels. A greater proportion of 2001 enrollees was uninsured for some time in the year before enrollment, was insured by Medicaid, and lacked a USC. Secular trends in the low-income population in the state did not seem to be responsible for these differences. Program modifications during this time period that may be related to the shift in enrollee characteristics include changes to benefits, outreach and marketing efforts, changes in the premium structure, and the advent of a single application form for multiple public programs. CONCLUSIONS: SCHIP enrollees are a diverse group, and there was considerable variation among the 5 study states. Overall, SCHIP enrollees had substantial and wide-ranging health care needs despite high levels of prior contact with the health care system. A sizable minority of SCHIP enrollees has special health care needs. There is racial and ethnic diversity in the composition of enrollees as well, with racial and ethnic disparities present. The quality of care adolescents received before enrollment in SCHIP was suboptimal, with many reporting unmet health care needs and not receiving recommended counseling. The characteristics of SCHIP enrollees can be expected to change as SCHIP programs evolve and mature. POLICY IMPLICATIONS: 1) Benefits should be structured to meet the needs of SCHIP enrollees, which are comparable to Medicaid enrollees' needs in many respects. 2) Provider networks will have to be broad if continuity of care is to be achieved. 3) Multiple outreach strategies should be used, including using providers to distribute information about SCHIP. 4) The quality of care delivered to vulnerable populations (eg, minority children, CSHCN, and adolescents) should be monitored. 5) States and health plans should actively promote quality health care with the goal of improving the care received by SCHIP enrollees before enrollment. 6) States will have to craft policies that fit their local context. 7) Collecting baseline information on SCHIP enrollees on a continuous basis is important, because enrollee characteristics and needs can change, and many vulnerable children are enrolling in SCHIP.

Computational prediction of operons in Synechococcus sp. WH8102.

We computationally predict operons in the Synechococcus sp. WH8102 genome based on three types of genomic data: intergenic distances, COG gene functions and phylogenetic profiles. In the proposed method, we first estimate a log-likelihood distribution for each type of genomic data, and then fuse these distribution information by a perceptron to discriminate pairs of genes within operons (WO pairs) from those across transcription unit borders (TUB pairs). Computational experiments demonstrated that WO pairs tend to have shorter intergenic distances, a higher probability being in the same COG functional categories and more similar phylogenetic profiles than TUB pairs, indicating their powerful capabilities for operon prediction. By testing the method on 236 known operons of Escherichia coli K12, an overall accuracy of 83.8% is obtained by joint learning from multiple types of genomic data, whereas individual information source yields accuracies of 80.4%, 74.4%, and 70.6% respectively. We have applied this new approach, in conjunction with our previous comparative genome analysis-based approach, to predict 556 (putative) operons in WH8102. All predicted data are available at (http://www.cs.ucr.edu/~xin/operons.htm) for public use.

Body area network--a key infrastructure element for patient-centered telemedicine.

The Body Area Network (BAN) extends the range of existing wireless network technologies by an ultra-low range, ultra-low power network solution optimised for long-term or continuous healthcare applications. It enables wireless radio communication between several miniaturised, intelligent Body Sensor (or actor) Units (BSU) and a single Body Central Unit (BCU) worn at the human body. A separate wireless transmission link from the BCU to a network access point--using different technology--provides for online access to BAN components via usual network infrastructure. The BAN network protocol maintains dynamic ad-hoc network configuration scenarios and co-existence of multiple networks.BAN is expected to become a basic infrastructure element for electronic health services: By integrating patient-attached sensors and mobile actor units, distributed information and data processing systems, the range of medical workflow can be extended to include applications like wireless multi-parameter patient monitoring and therapy support. Beyond clinical use and professional disease management environments, private personal health assistance scenarios (without financial reimbursement by health agencies / insurance companies) enable a wide range of applications and services in future pervasive computing and networking environments.

Student screening for inherited blood disorders in Bahrain.

In Bahrain and neighbouring countries inherited disorders of haemoglobin, i.e. sickle-cell disease, thalassaemias and glucose-6-phosphate dehydrogenase (G6PD) deficiency, are common. As part of the National Student Screening Project to determine the prevalence of genetic blood disorders and raise awareness among young Bahrainis, we screened 11th-grade students from 38 schools (5685 students), organized lectures and distributed information about these disorders. Haemoglobin electrophoresis, high performance liquid chromatography, blood grouping and G6PD deficiency testing were performed. Prevalences were: 1.2% sickle-cell disease; 13.8% sickle-cell trait; 0.09% beta-thalassaemia; 2.9% beta-thalassaemia trait; 23.2% G6PD deficiency; 1.9% G6PD deficiency carrier. Health education, carrier screening and premarital counselling remain the best ways to reduce disease incidence with potentially significant financial savings and social and health benefits.

Internet searching on internal medicine literature.

Internet technology for distributing information enormously supports the development of medical knowledge. Various medical resources on the internet are very helpful for the doctors' self-improvement; either on education, research, or health care application. Famous medical journals have made their online version, which can be accessed at any time and anywhere. However, there are extremely enourmous information that could be retrieved, so that the doctors should have appropriate strategy or measure to obtain the literature effectively and efficiently.

Marine and freshwater toxins.

In a very busy and exciting year, 2005 included First Action approval of a much needed official method for paralytic shellfish toxins and multiple international toxin symposia highlighted by groundbreaking research. These are the first-year milestones and activities of the Marine and Freshwater Toxins Task Force and Analytical Community. Inaugurated in 2004 and described in detail in last year's General Referee Report (1) this international toxins group has grown to 150 members from many regions and countries. Perhaps most important they are now making important and global contributions to food safety and to providing alternatives to animal-based assays. Official Method 2005.06 was first approved in late 2004 by the Task Force and subsequently Official First Action in 2005 (2) by the Methods Committee on Natural Toxins and Food Allergens and the Official Methods Board. This nonproprietary method (3) is a precolumn oxidation, liquid chromatographic method that makes good use of fluorescence detection to provide high sensitivity detection of the saxitoxins. It has also proven to be rugged enough for regulatory use and the highest level of validation. As pointed out in the report of method principle investigator and Study Director James Lawrence, approval of 2005.06 now provides the first official alternative to the mouse bioassay after many decades of shellfish monitoring. This past year in April 2005 the group also held their first international conference, "Marine and Freshwater Toxins Analysis: Ist Joint Symposium and AOAC Task Force Meeting," in Baiona, Spain. The 4-day conference consisted of research and stakeholder presentations and symposium-integrated subgroup sessions on ciguatoxins, saxitoxin assays and liquid chromatography (LC) methods for saxitoxins and domoic acids, okadaiates and azaspiracids, and yessotoxins. Many of these subgroups were recently formed in 2005 and are working towards their goals of producing officially validated analytical methods. (Abstracts from the Baiona 2005 meeting cited in this report can be found in the online version of the conference abstract book in the Files and Folders section of the Marine and Freshwater Toxins online community at www.aoac.org.) An active topic for discussion in Baiona and subsequent Task Force activities was the expert consultation for Codex which met in Oslo, Norway in 2004 (previously described and cited in last year's GR report, ref 1). The consultation group's executive summary report (http://www.fao.org/es/ESN/food/risk_biotoxin en.stm) describes suggested changes in action levels as well as methods, method validation, and other issues. September 2005 saw the AOAC Task Force efforts further supported by another symposium, "Marine and Freshwater Toxins: Quality Methods for Food Safety and International Trade," at the AOAC INTERNATIONAL Annual Conference in Orlando, Florida. The multidisciplinary talks at this full day symposium ranged from ciguatoxins to cyanobacterial toxins, and spanned toxicology, biochemistry, molecular biology and analytical chemistry. Again, the symposium preceded Task Force meetings. Toxin subgroups, including a new group on cyanobacterial toxins, met for engaging and productive subgroup discussions. All of these activities were preceded by a Wiley Award symposium for Task Force member Mike Quilliam of NRC Canada. These talks, presented at a half-day symposium on the first day of the Annual Meeting, focused on Quilliam's work with LC tandem mass spectrometry (LC/MS/MS) and certified reference standards and materials, and included related presentations by some of his many research collaborators. To maintain flow and continuity between symposia and between Task Force meetings, the group now uses new electronic discussion forums. Individual subgroup areas, under the Marine and Freshwater Toxins Task Force, comprise this online community. First introduced by AOAC INTERNATIONAL in early 2005, these new resources are being used to distribute information and to supplement the in-person subgroup meetings and electronic mail in the group's validation efforts.

Promoting bicycle helmets: a new focus for injury prevention.

Bicycle accidents cause many serious injuries and deaths in the United States, often as a result of head injury in riders not wearing helmets. Helmets reduce the incidence of head injury, and an aggressive safety education campaign has been shown to increase the number of children wearing helmets while riding. Such a campaign has been initiated in the Central Indiana area. The campaign is designed to educate families and to promote bicycle helmet use among children and their parents. Suggestions are given on how physicians can help educate, distribute information and encourage bicycle helmet use through their contact with families. A resource list is included so these materials can be easily obtained. Ultimately, we hope such a program will increase helmet use and consequently reduce morbidity and mortality from head injury in Indiana's children.
