ECOSOC's Agenda Should Include Noncommunicable Disease Threat In Developing Countries
"[E]xplicit indicators to measure progress in reducing heart diseases, stroke, diabetes, cancers and chronic respiratory diseases" are missing from the U.N. Economic and Social Council (ECOSOC) agenda as it meets in Geneva this week "to focus on implementing the internationally agreed goals and commitments in regard to public health," and the "omission needs to be urgently addressed if the intent is to have a major impact on reducing poverty by 2015," Ala Alwan, WHO"s assistant director-general for Noncommunicable Diseases and Mental Health; George Alleyne, PAHO"s director emeritus; and Martin Silink, president of the International Diabetes Federation write in an opinion piece in the Hindu.

A Urine Test For Appendicitis?
Appendicitis is the most common childhood surgical emergency, but the diagnosis can be challenging, especially in children, often leading to either unnecessary surgery in children without appendicitis, or a ruptured appendix and serious complications when the condition is missed. Now, emergency medicine physicians and scientists at the Proteomics Center at Children"s Hospital Boston demonstrate that a protein detectable in urine might serve as a "biomarker" for appendicitis. Their report was published online June 23 by the Annals of Emergency Medicine.

GOP State Sens. Ask Bayh, Lugar To Oppose DOJ Nominee Johnsen; Senate Confirms FDA Head Hamburg
In a May 15 letter to Sens. Evan Bayh (D-Ind.) and Dick Lugar (R-Ind.), 31 Republican Indiana state senators asked the lawmakers to oppose the confirmation of Indiana University law professor Dawn Johnsen, President Obama"s nominee to head the Office of Legal Counsel in the Justice Department, due to her support for abortion rights, the AP/Milwaukee Journal Sentinel reports. The state senators wrote that Johnsen"s support for abortion rights "is more than simply pro-choice" and that "she is pro-choice in an extremely radical way," citing Johnsen"s statements and writings. The letter, which was signed by all but two of the state"s Republican senators, asked Bayh and Lugar to consider what Johnsen"s nomination "could mean for the future of the country." Indiana Senate President Pro Tem David Long (R) said, "It"s a statement from a very strong pro-life caucus," adding, "It is not based on the fact she is pro-choice, it is based on the fact that she is radically so." According to Long, the letter originated with a request from Indiana Right to Life to urge Bayh and Lugar to oppose Johnsen"s confirmation.Johnsen in an e-mail said that as a nominee she would not make public comments to the media. White House spokesperson Amy Brundage said that Johnsen "will bring unquestioned integrity and a commitment to non-partisan interpretation of the law to the Office of Legal Counsel, and we"re pleased that both of Indiana"s senators have expressed support for her nomination." Lugar spokesperson Andy Fisher on Monday in an e-mail said that although the senator has said he would not oppose Johnsen"s confirmation, Senate Democrats currently do not have enough support to move forward with the confirmation process. Bayh supports Johnsen"s confirmation, according to Bayh spokesperson Eric Kleiman (Smith, AP/Milwaukee Journal Sentinel, 5/18).Senate Confirms Hamburg as FDA CommissionerThe Senate on Monday by voice vote confirmed the nomination of Margaret Hamburg to be FDA commissioner, CQ HealthBeat reports (CQ HealthBeat, 5/18). According to the AP/Washington Post, Hamburg"s priorities include leading the development of a swine flu vaccine and overhauling the U.S. food safety system. During her confirmation hearing, Hamburg, a bioterrorism expert, said that she wants to increase consumer confidence in the agency by increasing transparency and accountability. Previously, Hamburg served as an assistant health secretary under President Clinton (AP/Washington Post, 5/19).

Immune Genes Adapt To Parasites

Thank parasites for making some of our immune proteins into the inflammatory defenders they are today, according to a population genetics study that will appear in the June 8 issue of the Journal of Experimental Medicine (online May 25). The study, conducted by a team of researchers in Italy, also suggests that you might blame parasites for sculpting some of those genes into risk factors for intestinal disorders. Parasite-driven selection leaves a footprint on our DNA in the form of mutations known as "single nucleotide polymorphisms" (SNPs). Making sure that genetic variation (in the form of multiple SNPs) is maintained within certain immune genes over time helps ensure that the host can fend off different infections in different environments. In the new study, Matteo Fumagalli and colleagues sift through 1,052 SNPs in genes that code for immune proteins called interleukins from roughly 1000 people worldwide. Of 91 genes assessed, 44 bore signatures of evolutionary selection, meaning that the genetic variation was neither due to chance nor to the migration of populations over time. And some of that variation correlated with the diversity of parasites that live alongside humans. The data suggests that having lots of different parasites around has shaped the evolution of our interleukin genes. In general, parasitic worms appear to have had a more powerful influence on certain interleukin genes than smaller microbes such as viruses, bacteria, and fungi. That isn"t surprising, says senior author Manuela Sironi, because worms typically evolve slower than bacteria or viruses, giving their human hosts time to adapt in response. Some of the genes that were shaped by worm diversity made perfect sense, as the proteins they encode help generate the precise type of immune response required to rid the body of worms. Other genes, however, seemed to be influenced more by the diversity of viruses, bacteria, and fungi than by that of worms. SNPs in some of these genes are known risk alleles for inflammatory bowel diseases, such as Crohn"s and celiac disease. These "risky" alleles were probably maintained during evolution because they promote the kind of immune response needed to fend off viruses and bacteria. But this type of response also contributes to inflammatory bowel diseases. Fumagalli, M., et al. 2009. J. Exp. Med. doi: 10.1084/jem.20082779 Amy Maxmen Rockefeller University Press
