Workplace Toxins: A Hidden Epidemic
In his groundbreaking new book, The Formula for Better Health: How to Save Millions of Lives—Including Your Own, former CDC Director Dr. Tom Frieden draws on decades of experience leading public health efforts to reveal how to defeat the world's deadliest diseases. While the book covers many health threats, its principles are particularly relevant to one of America's most overlooked crises: occupational exposure to toxic substances.

Perspectives in Biological Monitoring of Inhaled Nanosized Particles
In this review, the authors synthesize published data of experimental studies on the distribution of inhaled nanoparticles and the first case reports to discuss the potential usefulness of their biological monitoring for clinical purposes.
Toxicokinetic studies suggest that nanoparticles may be absorbed predominantly by respiratory and oral routes with possible systemic translocation, leading to accumulation in the peripheral organs or excretion in feces or urine.
Some methods used in these studies may be applied successfully in retrospective evaluation of exposure or in follow-up of occupational exposure in the workplace. Biological monitoring of nanoparticles should be based on imaging methods that are essential to confirm their presence and to characterize them in tissue associated with analytical quantitative methods.
The first case reports reviewed emphasize the urgent need for the development of standardized procedures for the preparation and analysis of biological samples with a view to characterizing and quantifying nanoparticles.

Right to Die Debate Heating Up
Today's post by Brett Gowen of the California Bar is shared from fbgslaw.com
You may have heard about and seen the recent news coverage about Brittany Maynard, a 29 year old woman who is choosing to end her life after she was diagnosed with a terminal brain tumor last spring. Recently the Editorial Board of the Sacramento Bee advocated enactment of a “death with dignity law” similar to that adopted by Oregon 20 years ago. The Editorial Board contends that the Oregon model fully answers the concerns of those who have opposed “death with dignity” efforts in the past in the California.

Ask Well: Nanoparticles in Sunscreens
Today's post is shared from nytimes.com. Workers' in an outdoor environment are exposed the the sun's rays. The question arises as to whether present protective measures, ie. sunscreens are more harmful than helpful.
Titanium dioxide nanoparticles have been used increasingly in sunscreens in the last decade to protect the skin because the tiny particles directly absorb the radiation from sunlight, especially in the UVB range. But because the articles are so tiny — generally about 100 nanometers across, compared with about 3,000 to 9,000 nanometers for a speck of dust — some scientists have raised concerns about whether they might do harm by seeping through the skin and into the bloodstream.
Concerns grew when studies in mice showed that when injected under the skin, titanium dioxide caused inflammation . In addition, the International Agency on Cancer Research, part of the World Health Organization, decided in 2006 to classify titanium dioxide as a potential human carcinogen, based mostly on inhalation studies in animals, though the group called the evidence “conflicting at best.”
But research has largely dismissed such concerns about absorption, and most experts say that sunscreens containing nanoparticles can be safely used.
More recently, concerns have focused on the possibility that these nanoparticles could promote skin aging....

Reaching Towards a Healthier, Safer Workplace:NIOSH looks at healthcare worker familiarity with recommended respiratory protection practices
Every day healthcare workers (HCWs) make decisions about the best way to protect themselves. What would you do if you entered the room of a new patient and noticed symptoms such as fever and a mucus-producing cough? As a HCW, you must then ask yourself, “What type of disease does the patient have? What sort of precautions should I take to protect myself because the patient may have an infectious disease?” While it is your employer’s responsibility to provide policies, programs, training, and guidance on respirator use, it is the health care workers who implement these procedures. Do you know when to use respiratory protection? If so, do you understand what type of protection to choose and how to use it properly?NIOSH Research – the REACH II StudyResearchers at NIOSH conducted a study to determine HCW familiarity with recommended respiratory protection practices[i], [ii] including the selection of respiratory protective devices. NIOSH collaborated with several state health departments and universities for the Respirator Use Evaluation in Acute Care Hospitals (REACH II) study. REACH II involved 98 hospitals in six states, and surveyed over 1,500 HCWs, Hospital and Unit Managers. Research staff observed respirator donning (i.e., putting on) and doffing (i.e., taking off) demonstrations by more than 300 HCWs. To determine HCWs’ knowledge about which respiratory protection to use, both HCWs and managers were given six scenarios... |

ND workers' comp agency sues over computer project
Yet another reason for a universal integratable workers' compensation docketing program. Today's post is share from http://www.sacbee.com/.
BISMARCK, N.D. -- North Dakota's workers' compensation agency has sued a Chicago company over a failed $17 million computer system overhaul. The Workforce Safety and Insurance agency filed its lawsuit last month in state court against Aon eSolutions Inc. to recoup costs associated with the system that was never delivered. WSI hired Aon eSolutions in 2007 for a software system upgrade. The work was to cost $14 million, but it was plagued by delays and cost overruns and was never finished. The contract with the company expired in 2012, and WSI did not renew it. The state Legislature last year gave WSI $750,000 for potential litigation. WSI, which provides coverage for businesses when employees are hurt or killed on the job, alleges, among other things, negligence, fraud and deceit against the company in court papers. The agency has requested a jury trial. "Aon promised to deliver a state-of-the-art integrated software package that would replace WSI's existing software system and meet all of the agency's business needs," said WSI Director Bryan Klipfel said in a statement. "WSI intends to prove that Aon did not follow through on its promise. We are acting in the best interest of our stakeholders as we try to recover the money that was spent on this desired product." Aon said in a statement that it is "disappointed that WSI chose this course. We delivered substantial value to WSI and we did nothing wrong. We look forward to telling our side of... |

What Does Cancer Smell Like?
On a lab bench in Philadelphia sits a tiny box lined with nearly invisible nanotubes and gold. A clear plastic pipe runs through it, and a thicket of pins, each sprouting a red or blue wire, protrudes from its end. As air from the pipe wafts over the nanotubes, electrical signals surge out of the box along the wire threads. The whole apparatus is situated near a vial of blood, “sniffing” the air above it through the pipe.
The box, an electronic nose, is a key part of a theory being explored by George Preti, an organic chemist at the Monell Chemical Senses Center, and an interdisciplinary team that includes physicists and veterinarians at the University of Pennsylvania. Preti is an expert on human odors, having studied them for more than 40 years. He has sniffed — both with machines and with his nose — breath, sweat and other secretions in search of answers about why we smell the way we do. This latest project seeks to answer a question others might have never thought to ask: Does ovarian cancer have a smell?
In modern cancer medicine, doctors tend to rely on advanced imaging techniques and the detection of lumps. The widely acknowledged problem with these methods, though, is that by the time doctors have reason to order a scan or feel something, it’s often too late. Ovarian cancer has usually spread to other organs by the time it’s detected. If it is caught early — which happens only 15 percent of the time, often by accident when...

Sleep, Pain, and Hospital Workers
Today's post was shared by Safe Healthy Workers and comes from blogs.cdc.gov
Orfeu M. Buxton, PhD; Glorian Sorensen, PhD, MPH
We know that decreased sleep duration and extended shifts in healthcare workers are linked to workplace injuries. The effects of decreased sleep on pain in the workplace are less clear.
New research from the Harvard Center for Work, Health and Wellbeing –one of four NIOSH Centers of Excellence funded to explore and research the concepts of Total Worker Health™- examines the question: Does lack of sleep increase pain and limit function among hospital care workers?
The study, published in the American Journal of Occupational and Environmental Medicine, finds that sleep deficiency (including short sleep duration, insomnia symptoms, sleep insufficiency, or all three) is significantly associated with pain, functional limitations of daily living tasks due to that pain, and difficulty performing work tasks due to that pain, among hospital care workers.

Fashion Safety: US Endorses Bangladesh Action Plan
The following is a joint statement from the Department of Labor, Office of the United States Trade Representative, and the State Department:
"Today, the United States is outlining next steps in a longstanding effort to address in a meaningful way worker safety problems in Bangladesh — the severity of which were exemplified in the tragedies of the November 2012 Tazreen Fashions factory fire and the April 2013 Rana Plaza building collapse — and, more broadly, the ability of Bangladeshi workers to exercise their full range of labor rights.
On June 27, 2013, President Obama announced his decision to suspend Bangladesh's trade benefits under the Generalized System of Preferences (GSP) in view of insufficient progress by the Government of Bangladesh in affording Bangladeshi workers internationally recognized worker rights. That decision followed an extensive, interagency review under the GSP program of worker rights and worker safety in Bangladesh during which the U.S. Government encouraged the Government of Bangladesh to implement needed reforms. At the time of the announcement, the Administration provided the Government of Bangladesh with an action plan which, if implemented, could provide a basis for the President to consider the reinstatement of GSP trade benefits.

FDA Closes Down Illegal On-Line Pharmacies
Operation Pangea VI combats online sale and distribution of unapproved prescription medicines
The U.S. Food and Drug Administration, in partnership with international regulatory and law enforcement agencies, took action this week against more than 9,600 websites that illegally sell potentially dangerous, unapproved prescription medicines to consumers. These actions include the issuance of regulatory warnings, and seizure of offending websites and $41,104,386 worth of illegal medicines worldwide.
The action occurred as part of the 6th annual International Internet Week of Action (IIWA), a global cooperative effort to combat the online sale and distribution of potentially counterfeit and illegal medical products. As part of this year’s international effort – Operation Pangea VI – the FDA’s Office of Criminal Investigations, in coordination with the United States Attorney's Office for the District of Colorado, seized and shut down 1,677 illegal pharmacy websites. The effort ran from June 18 to June 25, 2013.
Many of these websites appeared to be operating as a part of an organized criminal network
that falsely purported its websites to be “Canadian Pharmacies.” These websites displayed fake licenses and certifications to convince U.S. consumers to purchase drugs they advertised as “brand name” and “FDA approved.” The drugs received as part of Operation Pangea were not from Canada, and were neither brand name nor FDA approved. These websites also used certain major U.S. pharmacy retailer names to trick U.S. consumers into believing an affiliation existed with these retailers.

Distracted Walkers Are a Workplace Hazard
Over the last 2 days I watched at least a half-a-dozen people walking in the streets with a cellphone in their hands, and totally ignoring all traffic signals and vehicles around them. We are too quick to blame workers for causing all accidents through the use of cellphones. Pedestrians on many occasions ignore all reason and logic, and walk in front of vehicles oblivious to the world.

Nanomaterials: NIOSH Publishes Safe Practices Guide
NIOSH (The National Institute for Occupational Safety and Health) has published safety recommendations on engineering controls and safe practices for handling engineered nanomaterials in laboratories and some pilot scale operations. This guidance was designed to be used in tandem with well-established practices and the laboratory’s chemical hygiene plan. The introduction of nanoparticles into the workplace has created a new dimension in workers' compensation occupational exposure claims.
"Nanotechnology, the manipulation of matter at a nanometer scale to produce new materials, structures, and devices having new properties, may revolutionize life in the future. It has the potential to impact medicine through improved disease diagnosis and treatment technologies and to impact manufacturing by creating smaller, lighter, stronger, and more efficient products. Nanotechnology could potentially decrease the impact of pollution by improving methods for water purification or energy conservation. Although engineered nanomaterials present seemingly limitless possibilities, they bring with them new challenges for identifying and controlling potential safety and health risks to workers. Of particular concern is the growing body of evidence that occupational exposure to some engineered nanomaterials can cause adverse health effects.
"As with any new technology or new material, the earliest exposures will likely occur for those workers conducting discovery research in laboratories or developing production processes in pilot plants. The research community is at the front line of creating new nanomaterials, testing their usefulness in a variety of applications and determining their toxicological and environmental impacts. Researchers handling engineered nanomaterials in laboratories should perform that work in a manner that protects their safety and health. This guidance document provides the best information currently available on engineering controls and safe work practices to be followed when working with engineered nanomaterials in research laboratories.

US Announces Effort to Prevent Emergency Responders From Occupational Illness
The National Institute for Occupational Safety and Health (NIOSH) and partners in the U.S. Centers for Disease Control and Prevention (CDC) today announced revised and updated resources to help prevent exposures of emergency response employees to potentially life-threatening infectious diseases in the line of duty.
The resources include:
- A list of potentially life-threatening infectious diseases, including emerging infectious diseases, and specifying those diseases routinely transmitted through airborne or aerosolized means.
- Guidelines describing the circumstances in which emergency response employees may be exposed to such diseases while attending to or transporting victims of emergencies.
- Guidelines for medical facilities making determinations whether such exposures have occurred.
The action was taken as a result of provisions in the Ryan White HIV/AIDS Treatment Extension Act of 2009. In the reauthorization, Congress directed the U.S. Department of Health and Human Services to update resources originally compiled under the Ryan White Comprehensive AIDS Resources Emergency Act, enacted in 1990.
The Secretary of Health and Human Services delegated the task to CDC. NIOSH and CDC’s Division of Healthcare Quality Promotion (DHQP) worked together to develop the required list and guidelines, incorporating input from stakeholders that was received via a public comment process. NIOSH was created under the Occupational Safety and Health Act of 1970 and is a part of CDC.
The updated list of potentially life-threatening infectious diseases which emergency response employees occupationally may be exposed include all that were in an earlier list under the 1990 Ryan White Act:
- Diphtheria
- Hepatitis B
- HIV, including AIDS
- Tuberculosis
- Viral hemorrhagic fevers
- Meningococcal disease
- Plague, pneumonic
- Rabies
New additions include:
- Anthrax, cutaneous
- Novel influenza A and other influenza strains with pandemic severity index greater than or equal to 3.
- Hepatitis C
- Measles
- Mumps
- Pertussis
- Rubella
- Severe acute respiratory syndrome (SARS-CoV)
- Smallpox
- Vaccinia
- Varicella disease
- Select agents
The notice of the action and further details can be found at http://www.gpo.gov/fdsys/pkg/FR-2011-11-02/html/2011-28234.htm

Deadly Delay: The Chemical Industry's Game Play
The Toxic Substances Control Act (TSCA) is in desperate need of reform. Its weaknesses have allowed chemical companies to exploit the act by thwarting the EPA's attempts to finalize health assessments and delaying regulation of chemicals -- sometimes for decades. The chemical industry's roadblocks often follow predictable patterns:
- Attack early drafts of health assessments
- Force new reviews
- Hold workshops populated with industry-funded panelists
- Introduce new industry-funded studies when assessments are close to final
- Force more reviews
- Enlist elected officials to assist with political interference
- Attack new assessment drafts
This report details how the U.S. legal system and TSCA itself have helped the chemical industry to be effective in its efforts to delay regulations. Congress needs to reform TSCA to make it a more effective regulatory tool. The chemical industry should not be able to endlessly postpone regulatory decisions while profiting from unregulated chemical sales until all scientific controversies and uncertainties, large and small, have been eliminated. With good public policy, the EPA should be empowered to make the best decisions it can on a timely basis using existing information, and apply new science to update its evaluations as it becomes available.
