Oneida nation of New York: health needs assessment 1990
This is the report of a health needs assessment for the Oneida Indian Nation of New York (ONNY). This needs assessment was conducted in order to collect population-based data related to behavioral risks and reproductive health for Oneida males and females. The survey of the Oneida was initiated because there is almost no risk factor data available on Indian tribes of the northeast, and none available for the Oneida Nation of New York. There are four primary goals for the 1990 Oneida Nation Health Needs Assessment. They are 1) to collect behavioral risk factor and reproductive health data for adult Oneida Nation members living on or near Oneida Nation lands, 2) to assess the current basic health needs of the ONNY, 3) to document the medical providers and hospitals which are currently being utilized by the Nation members and. 4) to develop recommendations for use by health planners from this baseline data.The Oneida Nation Health Needs Assessment (ONHNA) was carried out among enrolled members of the Oneida Nation who were 18 years of age and older who lived in the six counties that are contiguous to the Oneida Nation lands. The Nation Enrollment List was used to identify the Oneida population located in the six-county area. The choice to interview only adults was made to avoid legal difficulties in interviewing minors. Interviewing was conducted in each household face-to-face rather than using mailed questionnaires or telephone contact. All interviewers were enrolled Oneida Nation members. Interviews were conducted by interviewers of the same sex as the respondent. All interviewers participated in one week of training prior to the start of the field work. Four types of data were collected. First, the behavioral risk factors surveyed were related to the 10 leading causes of death in the United States. Behavioral factors include seat belt usage, physical exercise, diet, cigarette and smokeless tobacco usage, alcohol consumption, and the existence of high blood pressure. The second data set included health needs. The survey questions dealt with the prevalence of current diseases and health problems among the Oneidas, and with whether the Oneida people have routine screening tests such as cholesterol, diabetes, and hypertension, and eye exams, pap smears, breast exams, and rectal exams. The third set of data questions focused on reproductive health factors. Questions covered topics such as fertility, contraception, and general maternal-child health conditions. The fourth and final set of questions gathered data on health care utilization. This data will be used to establish health provider contracts with physicians, dentists, pediatricians, and hospitals to provide quality health care for a more reasonable cost. For each risk factor, comparisons were made between the Oneida Nation and data from the 1988 New York State Behavioral Risk Factor Survey.The individual completion rates were 54% for females and 69% for males for a total of 211 respondents in all. The following is an abbreviated summary of selected data from the survey. Seat belt use was only slightly lower than for all New Yorkers. Non-use was highest among young drivers. Sixty percent of Oneida males and 78 percent of Oneida females reported having their blood pressure taken within a year of the survey. All Oneida members were more active physically than the general New York population. However, all Oneida members were more likely to be overweight by comparison Forty percent of all Oneida people are smokers compared to 25 percent of the New York population. Fifty-seven percent of Oneida males and 32 percent of Oneida females are classified as acute and heavy drinkers. Percentages for regular health checks across all factors vary considerably among the Oneida people. Several areas of concern were identified including cholesterol checks, diabetes screening, rectal exams and mammograms. The completed fertility of the Oneida women in this survey is 2.1 children which is lower than that of all U.S. women surveyed in the 1980 census. Female sterilization is the most prevalent contraceptive method among Oneida women. as it is among the general U.S. population.With respect to behavioral risks, cigarette smoking and alcohol consumption are of major concern. This impacts on concerns for overall reproductive health. The task now is to identify the highest priority objectives and to secure resources needed to accomplish these tasks
Using global analysis, partial specifications, and an extensible assertion language for program validation and debugging
We discuss a framework for the application of abstract interpretation as an aid during program development, rather than in the more traditional application of program optimization. Program validation and detection of errors is first performed statically by comparing (partial) specifications written in terms of assertions against information obtained from (global) static analysis of the program. The results of this process are expressed in the user assertion language. Assertions (or parts of assertions) which cannot be checked statically are translated into run-time tests. The framework allows the use of assertions to be optional. It also allows using very general properties in assertions, beyond the predefined set understandable by the static analyzer and including properties defined by user programs. We also report briefly on an implementation of the framework. The resulting tool generates and checks assertions for Prolog, CLP(R), and CHIP/CLP(fd) programs, and integrates compile-time and run-time checking in a uniform way. The tool allows using properties such as types, modes, non-failure, determinacy,
and computational cost, and can treat modules separately, performing incremental analysis
Early and efficient detection of Mycobacterium tuberculosis in sputum by microscopic observation of broth cultures.
Early, efficient and inexpensive methods for the detection of pulmonary tuberculosis are urgently needed for effective patient management as well as to interrupt transmission. These methods to detect M. tuberculosis in a timely and affordable way are not yet widely available in resource-limited settings. In a developing-country setting, we prospectively evaluated two methods for culturing and detecting M. tuberculosis in sputum. Sputum samples were cultured in liquid assay (micro broth culture) in microplate wells and growth was detected by microscopic observation, or in Löwenstein-Jensen (LJ) solid media where growth was detected by visual inspection for colonies. Sputum samples were collected from 321 tuberculosis (TB) suspects attending Bugando Medical Centre, in Mwanza, Tanzania, and were cultured in parallel. Pulmonary tuberculosis cases were diagnosed using the American Thoracic Society diagnostic standards. There were a total of 200 (62.3%) pulmonary tuberculosis cases. Liquid assay with microscopic detection detected a significantly higher proportion of cases than LJ solid culture: 89.0% (95% confidence interval [CI], 84.7% to 93.3%) versus 77.0% (95% CI, 71.2% to 82.8%) (p = 0.0007). The median turn around time to diagnose tuberculosis was significantly shorter for micro broth culture than for the LJ solid culture, 9 days (interquartile range [IQR] 7-13), versus 21 days (IQR 14-28) (p<0.0001). The cost for micro broth culture (labor inclusive) in our study was US 11.35 per sample for the LJ solid culture. The liquid assay (micro broth culture) is an early, feasible, and inexpensive method for detection of pulmonary tuberculosis in resource limited settings
Effects of reducing beta-lactam antibiotic pressure on intestinal colonization of antibiotic-resistant gram-negative bacteria
Background: We determined the effects of two antibiotic policies (predominance of either β-lactam antibiotics or fluroquinolones) on acquisition with third-generation cephalosporin-resistant Enterobacteriaceae (CRE) and fluoroquinolone-resistant CRE (FCRE) in two ICUs, with monitoring of other variables that may influence acquisition. Methods: After an 8-month baseline period, units were randomized to a predominant β-lactam antibiotic regimen (weekly cycling of ceftriaxone, amoxicillin-clavulanic acid and fluroquinolones) or a fluoroquinolone regimen for 3 months, with cross-over for another 3 months. Acquisition of CRE and FCRE was determined by microbiological surveillance. Results: During baseline, acquisition rates for CRE and FCRE were 14/1,000 and 2/1,000 patient days at risk, respectively. Cross-transmission of CRE accounted for ≤25% of acquisitions, and CRE acquisition was associated with the use of β-lactam antibiotics (amoxicillin-clavulanic acid in particular). As compared to baseline, β-lactam antibiotic use [in defined daily dose (DDD)/1,000 patient days] was reduced from 854 to 526 (-39%) and 555 (-35%) during both intervention periods. Fluoroquinolone use was increased from 150 and 129 DDD/1,000 patient days in baseline and the β-lactam period to 514 DDD/1,000 patient days (+243%) in the fluoroquinolone period. Reductions in β-lactam use were not associated with reduced CRE acquisition [adjusted HRs were 1.0 (95% CR: 0.5-2.2) and 1.1 (95% CI: 0.5-2.5) during both periods, respectively]. Increased use of fluoroquinolones was associated with increased acquisition of FCRE [adjusted HR 4.1 (95% CI: 1.4-11.9; p < 0.01]. Infection control variables remained comparable during all periods. Conclusion: A 35-39% reduction of β-lactam exposure was not associated with reduced acquisition of CRE, whereas a 243% increase of fluoroquinolone use increased acquisition of FCRE
The pseudogap: friend or foe of high Tc?
Although nineteen years have passed since the discovery of high temperature
superconductivity, there is still no consensus on its physical origin. This is
in large part because of a lack of understanding of the state of matter out of
which the superconductivity arises. In optimally and underdoped materials, this
state exhibits a pseudogap at temperatures large compared to the
superconducting transition temperature. Although discovered only three years
after the pioneering work of Bednorz and Muller, the physical origin of this
pseudogap behavior and whether it constitutes a distinct phase of matter is
still shrouded in mystery. In the summer of 2004, a band of physicists gathered
for five weeks at the Aspen Center for Physics to discuss the pseudogap. In
this perspective, we would like to summarize some of the results presented
there and discuss its importance in the context of strongly correlated electron
systems.Comment: expanded version, 20 pages, 11 figures, to be published, Advances in

Human pluripotent embryonal carcinoma NTERA2 cl.D1 cells maintain their typical morphology in an angiomyogenic medium
BACKGROUND: Pluripotent embryonal carcinomas are good potential models, to study, "in vitro," the mechanisms that control differentiation during embryogenesis. The NTERA2cl.D1 (NT2/D1) cell line is a well known system of ectodermal differentiation. Retinoic acid (RA) induces a dorsal pattern of differentiation (essentially neurons) and bone morphogenetic protein (BMP) or hexamethylenebisacetamide (HMBA) induces a more ventral (epidermal) pattern of differentiation. However, whether these human cells could give rise to mesoderm derivatives as their counterpart in mouse remained elusive. We analyzed the morphological characteristics and transcriptional activation of genes pertinent in cardiac muscle and endothelium differentiation, during the growth of NT2/D1 cells in an inductive angiomyogenic medium with or without Bone Morphogenetic Protein 2 (BMP2). RESULTS: Our experiments showed that NT2/D1 maintains their typical actin organization in angiomyogenic medium. Although the beta myosin heavy chain gene was never detected, all the other 15 genes analyzed maintained their expression throughout the time course of the experiment. Among them were early and late cardiac, endothelial, neuronal and teratocarcinoma genes. CONCLUSION: Our results suggest that despite the NT2/D1 cells natural tendency to differentiate into neuroectodermal lineages, they can activate genes of mesodermal lineages. Therefore, we believe that these pluripotent cells might still be a good model to study biological development of mesodermal derivatives, provided the right culture conditions are met

Comparison of Beta-value and M-value methods for quantifying methylation levels by microarray analysis
First documented cure of a suggestive exogenous reinfection in polymyositis with same but multidrug resistant M. tuberculosis
BACKGROUND: MDR Mycobacterium tuberculosis is the major cause of treatment failure in tuberculosis patients, especially in immunosuppressed. We described a young polymyositis patient on immunosuppressive therapy who was started with antituberculosis therapy as a susceptible strain of M. tuberculosis was isolated from a single cutaneous abscess in his neck and from regional lymph nodes. CASE PRESENTATION: He had non-reactive miliary tuberculosis and multiple cutaneous abscesses 6 months later with the same strain, which was resistant this time to 9 antituberculosis drugs. We described clinical presentation, radiological and laboratory work-up, treatment and follow-up as the patient was cured after 1.5 years with 6 antituberculosis drugs. CONCLUSION: To our knowledge, this is the first reported case where an immunosuppressed patient with suggestive exogenous reinfection within 6 months with the same but MDR strain of M. tuberculosis was cured. Intense management and regular follow up were important since the patient was a potent source of MDR M. tuberculosis infection and there was limited choice for therapy
Enzyme Sequence and Its Relationship to Hyperbaric Stability of Artificial and Natural Fish Lactate Dehydrogenases
The cDNAs of lactate dehydrogenase b (LDH-b) from both deep-sea and shallow living fish species, Corphaenoides armatus and Gadus morhua respectively, have been isolated, sequenced and their encoded products overproduced as recombinant enzymes in E. coli. The proteins were characterised in terms of their kinetic and physical properties and their ability to withstand high pressures. Although the two proteins are very similar in terms of their primary structure, only 21 differences at the amino acid level exist between them, the enzyme from the deep-sea species has a significantly increased tolerance to pressure and a higher thermostability. It was possible to investigate whether the changes in the N-terminal or C-terminal regions played a greater role in barophilic adaptation by the construction of two chimeric enzymes by use of a common restriction site within the cDNAs. One of these hybrids was found to have even greater pressure stability than the recombinant enzyme from the deep-living fish species. It was possible to conclude that the major adaptive changes to pressure tolerance must be located in the N-terminal region of the protein. The types of changes that are found and their spatial location within the protein structure are discussed. An analysis of the kinetic parameters of the enzymes suggests that there is clearly a trade off between Km and kcat values, which likely reflects the necessity of the deep-sea enzyme to operate at low temperatures
