H1N1 Death Toll Doubles Over Last Month; First Vaccine Trial Begins
The worldwide death toll from the H1N1 (swine flu) virus has doubled in the past month, reaching over 700, the WHO announced Tuesday, the AP/Google.com reports. "WHO did not give a breakdown of the deaths Tuesday. But as of last week, the U.S. reported 263 deaths, Canada reported 45 deaths and Britain had 29. According to WHO"s last update on July 6, there were 119 deaths in Mexico," the news service writes. "Yet even Tuesday"s figure of 700 deaths may seriously underestimate the true toll, experts say, because not all swine flu cases are being picked up due to testing limitations" (Jordans, 7/21).

Protesters Disrupt Democrats' Best-Laid Plans For Health Reform 'Conversations'
Over the weekend, a series of protests at Democratic events meant to promote health reform "organized by loose-knit coalition of conservative voters and advocacy groups, were a raucous start to what is expected to be weeks of political and ideological clashes over the health care overhaul," the New York Times reports. "Republicans said that the protests were just the beginning of spontaneous opposition to the health care proposals and that they would only gain momentum as Americans learn more about the legislation." But Democrats said they were only an effort to block discourse, and were anything but a grass-roots campaign. "This is a very coordinated effort," said one Democratic Congressman who was confronted by protestors at a grocery store (Herszenhorn and Stolberg, 8/3).

Illicit Drug Use Mapped Using Wastewater

A team of researchers has mapped patterns of illicit drug use across the state of Oregon using a method of sampling municipal wastewater before it is treated. Their findings provide a one-day snapshot of drug excretion that can be used to better understand patterns of drug use in multiple municipalities over time. Municipal water treatment facilities across Oregon volunteered for the study to help further the development of this methodology as a proactive tool for health officials. Applying analytical methods advanced at Oregon State University, researchers from the University of Washington, McGill University and OSU collected single-day samples from 96 municipalities across Oregon and tested the samples for evidence of methamphetamine, cocaine, and "ecstasy" or MDMA. The study, published this week in the journal Addiction, reports a demonstration of this methodology conducted by UW drug epidemiologist Caleb Banta-Green, OSU chemist Jennifer Field, OSU toxicologist Daniel Sudakin, McGill spatial epidemiologist Luc de Montigny, OSU faculty research assistant Laura Power and OSU graduate student Aurea Chiaia. "This work is the first to demonstrate the use of wastewater samples for spatial analyses, a relatively simple and cost-effective approach to measuring community drug use," said Banta-Green, lead author of the paper. "Current measures of the true prevalence of drug use are severely limited both by cost and methodological issues. We believe these data have great utility as a population measure of drug use and provide further evidence of the validity of this methodology." "Municipalities across the state generously volunteered to help us test our methods by collecting samples more or less simultaneously, providing us with 24-hour composite influent samples from one day -- March 4, 2008," said Field, who led the laboratory analyses of the samples. Using these samples from 96 municipalities, representing 65 percent of Oregon"s population, the researchers calculated the presence, measured as index loads, of three stimulant drugs: methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA, or ecstasy), and benzoylecgonine (BZE, a cocaine metabolite). They found that the index loads of BZE were significantly higher in urban areas and below the level of detection in some rural areas. Methamphetamine was present in all municipalities, rural and urban. MDMA was at quantifiable levels in less than half of the communities, with a significant trend toward higher index loads in more urban areas. Researchers said the study validates wastewater drug testing methodology that could serve as a tool for public health officials. Officials could, for example, use the methodology to identify patterns of drug abuse across multiple municipalities over time. The research team underscored, too, that data used for this study are inadequate as a complete measure of drug excretion for a community or entire state. The team looked at a single day, mid-week sample, for instance. Results might be altered depending on the day or time of year the sample was gathered. "We believe this methodology can dramatically improve measurement of the true level and distribution of a range of illicit drugs. By measuring a community"s drug index load, public health officials will have information applicable to a much larger proportion of the total population than existing measures can provide," said Banta-Green. Currently, Field and Banta-Green are working on a project funded by the National Institutes of Health to determine the best method for collecting data in order to get a reliable annual estimate of drug excretion for a community.
