Friday, July 04, 2003, 12:18 EDT (12:18 AM EDT)CDCHAN-00150-03-07-04-UPD-NThis notice is an update to the press release distributed by the United States Department of Agriculture, Food Safety and Inspection Service (FSIS) on June 29, 2003.Health authorities in Minnesota have identified three residents with E. coli O157:H7 infection associated with steaks produced by Stampede Meat, Inc. of Chicago Ill. To date, 16 persons with confirmed E. coli O157:H7 infections in 12 states have been associated with the outbreak. Investigators have also isolated the outbreak strain of E. coli O157:H7 from leftover steak consumed by an infected child.Stampede Meat, Inc. issued a recall on June 29, 2003, of approximately 739,000 pounds of frozen meat produced from March 17 through March 22, 2003. Stampede Meat, Inc. bears the USDA establishment code of "EST. 19113" and is sold under a variety of brand names. Stampede Meat, Inc. meat, potentially contaminated by E. coli O157:H7, has been distributed to retail grocery stores, restaurants, institutions and to door-to-door meat sales companies in at least 18 states.Whole steak is not usually associated with E. coli O157:H7 outbreaks. The meats produced by Stampede Meat, Inc. are subject to one or more processes that can introduce surface contamination into the center of the meat, including needle tenderization and injection of flavor enhancing additives. The meat is sold frozen. Because E. coli O157:H7 contamination may be internal to the steak, cooking the surface may not be adequate to kill the contaminating E. coli O157:H7. In addition, because it is sold and stored frozen, the meat has a long shelf-life. The implicated meat has a "best if used by" date of September 13 through 18, 2003. Thus people may still have implicated meat potentially contaminated with E. coli O157:H7. Consumers should not eat the implicated meat and should return the recalled products to the point of purchase.Public health officials at state and local health departments, the Centers for Disease Control and Prevention, and FSIS are continuing to investigate this outbreak. Meat potentially contaminated by E. coli O157:H7 should not be eaten. E. coli O157:H7 infection often causes severe bloody diarrhea and abdominal cramps; sometimes the infection causes nonbloody diarrhea or no symptoms. Usually little or no fever is present, and the illness resolves in 5 to 10 days. In some persons, particularly children under 5 years of age and the elderly, the infection can also cause a complication called hemolytic uremic syndrome, in which the red blood cells are destroyed and the kidneys fail. About 2%-7% of infections lead to this complication.

June 3, 2011, 9:30 a.m. ESTCDCHAN-00322-ADV-NCDC is monitoring a large outbreak of Shiga toxin-producing Escherichia coli 0104:H4 (STEC 0104:H4) infections ongoing in Germany. The responsible strain shares virulence characteristics with enteroaggregative E. coli (EAEC). As of May 31, 2011, the Robert Koch Institute (RKI) reported 470 patients with hemolytic uremic syndrome, or HUS (a severe condition associated with STEC infection that can lead to kidney failure), and nine deaths. The strain of STEC that is causing this illness, STEC 0104:H4 is very rare. The illness that it causes is similar to that caused by E. coli 0157:H7 or STEC 0157:H7, which is also a Shiga toxin-producing E. coli.2011Shiga-Toxigenic Escherichia coli Infections, 2011BacteriaShiga-Toxigenic Escherichia coli O104-H

Assortative Marriage and the Effects of Government Homecare Subsidy Programs on Gender Wage and Participation Inequality

We develop a model of the labor market where firms incur an adjustment cost when one of their workers quits, and males and females form households assortatively by skill. We show how this environment can lead to an economy where females earn less and drop out more frequently than equally skilled males in equilibrium, even when males and females constitute ex-ante identical populations. We then examine how different government homecare subsidy schemes may affect such gender inequality in the labor market. We show that the effect of government homecare subsidy schemes on gender inequality depends crucially on the form in which the subsidy is given and to whom it is allocated.Gender Inequality, Discrimination, Subsidized Childcare

Thursday, December 14, 2006, 13:50 EST (1:50 PM EST)CDCHAN-00255-2006-12-14-UPD-NAs of Wednesday, December 13, 2006, 71 persons have become ill with Escherichia coli 0157:H7 associated with eating contaminated lettuce at Taco Bell restaurants in the northeastern United States. Cases have been reported to CDC from five states: New Jersey (33), New York (22), Pennsylvania (13), Delaware (2) and South Carolina (1). Other cases of illness are under investigation by state public health officials. Among the 71 persons with illness, 53 (75 %) were hospitalized and 8 (11%) developed a type of kidney failure called hemolytic-uremic syndrome (HUS). Illness onset dates have ranged from November 20-December 6. New cases have declined substantially. The last week of November was the peak time when persons became ill.Of the 71 persons with illness, 48 have been confirmed as cases. Strains are routinely "DNA fingerprinted" by laboratories in all 50 states as part of CDC's PulseNet Network (the network of public health laboratories that subtype bacteria). E. coli 0157 strains from other cases are being tested by PulseNet. As a result of testing, cases found with the outbreak strain "fingerprint" are being re-classified as confirmed cases and cases with an unrelated "fingerprint" pattern are being dropped from the case count. There have been no illnesses with onset within the past 5 days among identified cases, including suspects; therefore, the outbreak has ended.Concerning the outbreak of E. coli O157 infections associated with Taco John's restaurants, Minnesota and Iowa are reporting 27 and 50 associated illnesses, respectively. Isolates from these outbreaks cases of E. coli O157 demonstrate indistinguishable patterns, confirming that the two clusters are linked. However, this pattern is distinct from the Taco Bell outbreak pattern. One other matching isolate from Wisconsin has been identified. Investigators in Minnesota and Iowa have independently identified lettuce as the contaminated food vehicle in that outbreak. Trace back efforts are underway.2006Spinach-related E. coli outbreak (Sep-Oct 2006)BacteriaEscherichia coli O157-H

Thursday, May 20, 2004, 16:01 EDT (4:01 PM EDT)CDCHAN-00201-2004-05-20-ADV-NOn May 12, 2004, the Oregon Department of Human Services State Health Division identified five cases of Salmonella serotype Enteritidis (SE) infections with isolates having indistinguishable pulsed-field gel electrophoresis (PFG E) patterns. In the five days before illness, all patients had consumed raw almonds produced by Paramount Farms and sold under the Kirkland Signature label through Costco stores. The link between illness and consumption of raw almonds was a statistically significant finding when patients were compared with other persons in the community.A review of recent SE isolates submitted to PulseNet, the National Molecular Subtyping Network for Foodborne Disease Surveillance, revealed 17 additional isolates from 9 states, for a total of 22 S E isolates with the outbreak-associated PFGE pattern (Alaska 1, Arizona 2, Idaho 2, Massachusetts 1, Michigan 3, Oregon 6, Tennessee 1, Utah 2, Washington 4). Ages of case-patients range from 11 months to 91 years with illness onset dates from June 2003 to April 2004. Of sixteen patients with known medical data, 5 were hospitalized and no one died. SE isolates from 2004 continue to be analyzed and case finding is ongoing.2004Salmonella Food Poisoning, 2004BacteriaSalmonella enteritidi

The Applicability of the Astrometric Method in Determining the Physical Parameters of Gravitational Microlenses

In this paper, we investigate the applicability of the astrometric method to the determination of the lens parameters for gravitational microlensing events toward both the LMC and the Galactic bulge. For this analysis, we investigate the dependency of the astrometrically determined angular Einstein ring radius, $\Delta(\theta_{\rm E}/\theta_{\rm E,0})$, on the lens parameters by testing various types of events. In addition, by computing $\Delta(\theta_{\rm E}/\theta_{\rm E,0})$ for events with lensing parameters which are the most probable for a given lens mass under the standard models of Galactic matter density and velocity distributions, we determine the expected distribution of the uncertainties as a function of lens mass. From this study, we find that the values of the angular Einstein ring radius are expected to be measured with uncertainties $\Delta(\theta_{\rm E}/\theta_{\rm E,0}) \lesssim 10$ up to a lens mass of $M\sim 0.1 M_\odot$ for both Galactic disk-bulge and halo-LMC events with a moderate observational strategy. The uncertainties are relatively large for Galactic bulge-bulge self-lensing events, $\Delta(\theta_{\rm E}/\theta_{\rm E,0}) \sim 25$ for $M\sim 0.1 M_\odot$, but they can be substantially reduced by adopting more aggressive observational strategies. We also find that although astrometric observations can be performed for most photometrically detected Galactic bulge events, a significant fraction ($\sim 45$) of LMC events cannot be astrometrically observed due to the faintness of their source stars.Comment: 16 pages, including 2 tables and 4 figures, submitted to Monthly Notices of the Royal Astronomical Socirt

Higgs boson production and decay at e+e−e^{+}e^{-} colliders as a probe of the Left-Right twin Higgs model

In the framework of the Left-Right twin Higgs (LRTH) model, we consider the constrains from the latest search for high-mass dilepton resonances at the LHC and find that the heavy neutral boson $Z_H$ is excluded with mass below 2.76 TeV. Under these constrains, we study the Higgs-Gauge coupling production processes $e^{+}e^{-}\rightarrow ZH$, $e^{+}e^{-}\rightarrow \nu_{e}\bar{\nu_{e}}H$ and $e^{+}e^{-}\rightarrow e^{+}e^{-}H$, top quark Yukawa coupling production process $e^{+}e^{-}\rightarrow t\bar{t}H$, Higgs self-couplings production processes $e^{+}e^{-}\rightarrow ZHH$ and $e^{+}e^{-}\rightarrow \nu_{e}\bar{\nu_{e}}HH$ at $e^{+}e^{-}$ colliders. Besides, we study the major decay modes of the Higgs boson, namely $h\rightarrow f\bar{f}$($f=b,c,\tau$), $VV^{*}(V=W, Z)$, $gg$, $\gamma\gamma$. We find that the LRTH effects are sizable so that the Higgs boson processes at $e^{+}e^{-}$ collider can be a sensitive probe for the LRTH model.Comment: Final version to appear in Nucl.Phys.
