Blogs Comment On World Population Day, Health Care Reform, Other Topics
The following summarizes selected women"s health-related blog entries. ~ "World Population Day 2009 -- Time To Finally Make Maternal Health a Priority," Sharon Camp, Huffington Post blogs: World Population Day on Saturday "serves as an urgent reminder that ... governments around the world must boost investments in global health," especially maternal health, despite the global economic recession, Camp, president and CEO of the Guttmacher Institute, writes. Efforts "have fallen short" to date as the "financial res and political will needed to promote maternal health have been lagging," Camp writes. She notes that the nations are "hardly any closer" to achieving the United Nations" Millennium Development Goals of reducing maternal deaths by 75% and achieving universal access to reproductive health services by 2015. A "critical shortcoming" of recent efforts to achieve the MDGs has been the "reluctance of some governments and advocates to accept that better maternal health cannot be achieved without acknowledging, committing and fully funding sexual and reproductive health services," Camp writes. In particular, "this includes contraceptive services to help women time and space pregnancies as well as treatment of septic or incomplete abortions," and "providing safe abortion services consistent with individual country law," according to Camp. However, there is "some good news," she writes, noting that "[n]ew momentum behind worldwide advocacy efforts may yield the res and political commitment needed to make a difference." Camp concludes, "It is precisely because res are scarce that they must be used wisely and efficiently in a way that serves both humanitarian and economic development goals. Investing in saving women"s lives fits this bill" (Camp, Huffington Post blogs, 7/9).~ "Proposed Amendments Would Deny Health Care to Women," Lois Uttley, RH Reality Check: In a blog post addressed to "Gentlemen of the Congress," Uttley asks if they have "forgotten about the women" in their lives as they work on crafting health care reform legislation. Uttley writes,"[S]ome of you are wasting valuable time and taxpayer dollars proposing amendments that would deny health care" to several groups of people, including women. She writes that Republican Sens. Mike Enzi (Wyo.), Orrin Hatch (Utah) and Tom Coburn (Okla.) this week submitted amendments to the Senate Health, Education, Labor and Pensions Committee that would ban coverage for abortion services; protect health care providers and insurers from ""discrimination" for refusing to provide health care requested by their patients," including abortion and emergency contraception; allow federally qualified health centers to "not provide abortions and still get government grants"; and require that "[a]ny independent medical board appointed to determine the benefits that would be included in national health reform coverage would have to include "professional ethicists ... with specialty in rights of the life of the unborn."" Meanwhile, Democrats "are spending far too much time trying to win over colleagues who are never going to vote for health reform, no matter if you offer them abortion exclusions or new provider "conscience" laws or other provisions that would hobble health reform," Uttley writes. She continues, "Don"t forget that women are among the strongest supporters of moving quickly on health reform this year" because they are "grassroots experts on what is broken in the current health system," such as insurers" labeling of pregnancy as a "pre-existing condition," using "gender rating" in individual policies and excluding contraception coverage. She asks, "So what do women want?" Uttley provides a "list we"ve been compiling at Raising Women"s Voices for the Health Care We Need." Among the priorities, the list stresses that lawmakers should keep "moral values" out of the debate and that health insurance must be affordable, more simple to understand, fair, portable and universal (Uttley, RH Reality Check, 7/9).~ "Reports

Nanodiamonds, The New Tool For Next-Generation Cancer Treatments

A research team at Northwestern University has demonstrated a tool that can precisely deliver tiny doses of drug-carrying nanomaterials to individual cells. The tool, called the Nanofountain Probe, functions in two different ways: in one mode, the probe acts like a fountain pen, wherein drug-coated nanodiamonds serve as the ink, allowing researchers to create devices by "writing" with it. The second mode functions as a single-cell syringe, permitting direct injection of biomolecules or chemicals into individual cells. The research was led by Horacio Espinosa, professor of mechanical engineering, and Dean Ho, assistant professor of mechanical and biomedical engineering, both at the McCormick School of Engineering and Applied Science at Northwestern. Their results were recently published online in the scientific journal Small. The probe could be used both as a research tool in the development of next-generation cancer treatments and as a nanomanufacturing tool to build the implantable drug delivery devices that will apply these treatments. The potential of nanomaterials to revolutionize drug delivery is emergent in early trials, which show their ability to moderate the release of highly toxic chemotherapy drugs and other therapeutics. This provides a platform for drug-delivery schemes with reduced side effects and improved targeting. "This is an exciting development that complements our previous demonstrations of direct patterning of DNA, proteins and nanoparticles," says Espinosa. Using the Nanofountain Probe, the group injected tiny doses of nanodiamonds into both healthy and cancerous cells. This technique will help cancer researchers investigate the efficacy of new drug-nanomaterial systems as they become available. The group also used the same Nanofountain Probes to pattern dot arrays of drug-coated nanodiamonds directly on glass substrates. The production of these dot arrays, with dots that can be made smaller than 100 nanometers in diameter, provides the proof of concept by which to manufacture devices that will deliver these nanomaterials within the body. The work addresses two major challenges in the development and clinical application of nanomaterial-mediated drug-delivery schemes: dosage control and high spatial resolution. In fundamental research and development, biologists are typically constrained to studying the effects of a drug on an entire cell population because it is difficult to deliver them to a single cell. To address this issue, the team used the Nanofountain Probe to target and inject single cells with a dose of nanodiamonds. "This allows us to deliver a precise dose to one cell and observe its response relative to its neighbors," Ho says. "This will allow us to investigate the ultimate efficacy of novel treatment strategies via a spectrum of internalization mechanisms." Beyond the broad research focused on developing these drug-delivery schemes, manufacturing devices to execute the delivery will require the ability to precisely place doses of drug-coated nanomaterials. Ho and colleagues previously developed a polymer patch that could be used to deliver chemotherapy drugs locally to sites where cancerous tumors have been removed. This patch is embedded with a layer of drug-coated nanodiamonds, which moderate the release of the drug. The patch is capable of controlled and sustained low levels of release over a period of months, reducing the need for chemotherapy following the removal of a tumor. "An attractive enhancement will be to use the Nanofountain Probe to replace the continuous drug-nanodiamond films currently used in these devices with patterned arrays composed of multiple drugs," Ho says. "This allows high-fidelity spatial tuning of dosing in intelligent devices for comprehensive treatment." "One of the most significant aspects of this work is the Nanofountain Probe"s ability to deliver nanomaterials coated with a broad range of drugs and other biological agents," Espinosa says. "The injection technique is currently being explored for delivery of a wide variety of bio-agents, including DNA, viruses and other therapeutically relevant materials." Nanodiamonds have also proven effective in seeding the growth of diamond thin films. These diamond films have exciting applications in next-generation nanoelectronics. Here again, the ability to pattern nanodiamonds with sub-100-nanometer resolution provides inroads to realizing these devices on a mass scale. The resolution in nanodiamond patterning demonstrated by the Nanofountain Probe represents an improvement of three orders of magnitude over other reported direct-write schemes of nanodiamond patterning. The work was supported by the National Science Foundation, the National Institutes of Health, the V Foundation for Cancer Research and the Wallace H. Coulter Foundation. In addition to Espinosa and Ho, other authors of the paper, entitled "Nanofountain Probe-based High-resolution Patterning and Single-cell Injection of Functionalized Nanodiamonds," are Owen Loh, Robert Lam, Mark Chen, Nicolaie Moldovan and Houjin Huang of Northwestern University.
