Seems pretty obvious â€“ if a sunscreen with an SPF of 30 is good, then an SPF of 100 should be at least three times as good.
Unfortunately, that is not the case.Â There are other important details to consider when you are purchasing a sunscreen.
â€œPeople have become much more educated about the importance of using sunscreen, and manufacturers have responded with an abundance of products,â€ says Carl Washington, MD, associate professor of Dermatology at Emory University School of Medicine. â€œUnfortunately, the labeling can be confusing and many of the current sunscreens only contain the ingredients necessary to offer protection against sunburn, but not skin cancer or aging.â€
Recently, the Food and Drug Administration created new regulations to establish standards for sunscreen manufacturers to follow before they label their products.
Under the new regulations, which will go into effect in 2012, sunscreen products that protect against alltypes of sun-induced skin damage will be labeled â€œbroad spectrumâ€ and â€œSPF 15â€ or higher on the container. Only products that have been tested to ensure they protect against both UVA (ultraviolet radiation A) and UVB (ultraviolet radiation B) radiation will be allowed to use this labeling.Â Broad-spectrum sunscreens of SPF 15 and higher can also be labeled as protective against skin cancer and premature aging. The maximum SPF value is set at 50-plus because the FDA says anything higher doesnâ€™t provide a significant amount of additional protection.
Manufacturers will have to include warning labels on products that are not broad spectrum. Products that claim to be water resistant must indicate how long the consumer should expect to be protected in the water, and using such language as â€œwaterproofâ€ or â€œsweat proofâ€ will not be allowed.
â€œSkin cancer is the most common form of cancer in the United States, and the number of people affected keeps rising. Simply getting into the habit of using a sunscreen every day – with the appropriate levels of protection – can make a significant difference in preventing many skin cancers, as well as premature aging,â€ says Washington.
â€œThese new regulations will help consumers understand the difference in degrees of sun protection, and choose carefully.â€
Washington also suggests staying out of direct sunlight between 10 am and 2 pm, seeking shade when you are outdoors, remembering to reapply sunscreen every two hours and wearing protective clothing.
Sperling and his panel colleagues reviewed information about 20 well-known diets, from Atkins to Zone, and rated each one on specific measures such as safety, easiness to follow and nutritional completeness.
Using the expertsâ€™ ratings, U.S. News developed five diet categories to address a broad range of consumersâ€™ dieting goals and needs including Best Diabetes Diets, Best Heart Diets, Best Weight Loss Diets and Best Overall. “The goal of the Best Diets rankings is to help consumers find authoritative guidance on healthful diets that will work for them over the long haul,” said Lindsay Lyon, U.S. News‘s Health News Editor.
Weight Watchers ranked first in the Weight Loss category. Tied for number two were Jenny Craig and the Raw Food Diet, an approach that challenges dieters to avoid foods that have been cooked.
The government-endorsed DASH Diet took the top spot as the best diet overall. Three diets tied at number two, excelling in all measures U.S News considered: the Mediterranean Diet, the TLC Diet, and Weight Watchers.

A womanâ€™s body shape – often described as pear, apple or hourglass – is usually determined by the amount of fat in various regions of the body including the bust, waist, arms and hips. New research from Emory University School of Medicine suggests that these patterns of fat distribution may help predict arterial stiffness â€“ a precursor to cardiovascular disease.
Stiff arteries make the heart work harder to pump blood and are associated with atherosclerosis, or the buildup of plaques in vessels that can block blood flow and cause a heart attack.
Noting that fat distribution generally differs between black and white womenâ€™s bodies, researchers enlisted 68 black women and 125 white women, all middle-aged, to see whether these patterns could help assess cardiovascular risk.
Using skin calipers, the researchers measured subcutaneous fat in seven sites: the upper chest; midaxillary, or the side of the torso just under the armpit; triceps, or the back of the arm; subscapular, or on the back just below the shoulder blade; abdominal; suprailiac, or just above the front of the hip bone; and the thigh.
â€œBlack women have higher rates of cardiovascular disease than white women and are more likely to die from it,â€ says Eapen. â€œBlack and white women also have different patterns of fat distribution, so we were interested in measuring these pockets of fat at various regions of the body to evaluate whether it might be helpful in predicting cardiovascular risk between the two groups.Â Our hope was to evaluate whether a quick, easy-to-use clinical tool could aid in further risk stratifying our female patients.â€
The study also assessed the arterial stiffness of the women, adjusting for heart rate.
As a group, the black women had greater arterial stiffness than the white women. They also had more subcutaneous fat in the armpit, triceps, shoulder blade and hip bone areas.
In addition, they also found specific race dependent pockets of fat that could be related to arterial stiffness â€“ fat measurements in the triceps area could predict increased arterial stiffness in black women, while fat in the suprailiac areas was a predictor in white women.

Healthcare Heroes award winners Dean Thomas Lawley and Dr. Ursula Kelly
This weekâ€™s issue of the Atlanta Business Chronicle spotlights the winners of its annual Healthcare Heroes Awards, recognizing the contributions of top medical professionals in the Atlanta health care community. Emory was well represented again this year among the impressive list of winners and finalists. Winners included:
Linda Cendales, MD, assistant professor of Surgery at Emory University School of Medicine, nominated in the Healthcare Innovations category for successfully performing the stateâ€™s â€“ and one of the nationâ€™s â€“ first hand transplants on a college student from Orlando, Fla. (see Emory article)
Katherine L. Heilpern, MD, professor and chair of the department of emergency medicine, nominated in the Physician category for her contributions to emergency and trauma care and for her leadership among 5 hospitals in Metro Atlanta which receive 250,000 patient visits per year.
Curtis Lewis, MD, assistant professor of radiology, Emory University School of Medicine, nominated in the Physician category for his management and training of physicians and residents in his role as chief of staff and senior vice president of medical affairs at Grady.
Approximately 250,000 people each year suffer from a particularly deadly form of heart attack known as a STEMI (ST-Elevation Myocardial Infarction), in which blood flow is completely blocked to the heart. Restoring blood flow quickly is crucial in order to save the patientâ€™s life, yet more than 30 percent of these patients receive no life-saving intervention at all.
Michael Ross, MD
Led by Emory emergency medicine physician Michael Ross, the Society of Chest Pain Centers (SCPC) and the American Heart Association (AHA) recently announced they will be joining efforts to save even more lives. The joint agreement seeks to improve cardiac care, specifically the care of patients suffering from STEMI.
The new collaborative framework for hospital accreditation meets criteria of the AHA initiative â€œMission: Lifeline,” established in 2007 to improve the processes surrounding care of the STEMI patient by eliminating the obstacles that keep patients from accessing and receiving appropriate treatments.
Mission: Lifeline systems start with the 9-1-1 call or at the point of entry in the emergency system, continue through the catheterization laboratory and through hospital discharge by promoting best practices that use the latest scientific evidence-based treatment for STEMI.
Mission: Lifeline systems currently cover more than 56 percent of the United States. Mortality rates from STEMI have decreased from 5.8 percent in 2008 to 4.8 percent in 2010.
â€œSCPC, through their Chest Pain Center accreditation, has already improved cardiac processes in close to 14 percent of hospitals within the U.S. and has moved this accreditation to the international setting,â€ says Ross, who is immediate-past SCPC president and an associate professor of emergency medicine and medical director for observation medicine at Emory.
â€œCollaboration between these two non-profit organizations, who share similar missions, will help bring consistency to health care delivery by providing a standard approach to the treatment of STEMI. Providing cardiac accreditation programs is in the best interest of patients, meets the needs of the health care community, and will help to significantly reduce cardiac deaths.â€
Most commonly known as coronary angioplasty, PCI is a therapeutic procedure to treat the narrowed coronary arteries of the heart found in coronary heart disease. The designation is a distinguishing attribute since PCI is now the preferred treatment for heart attack patients.

When Jon Pomenville of Anderson, SC, decided to donate a kidney altruistically to someone â€“ anyonein need, anywhere in the country â€“ little did he know his selfless sacrifice would in turn change the lives of not one, but numerous individuals and their families, including one little boy from Atlanta.
And little did he know that the selfless, anonymous act would quickly become not so anonymous. During a recent post-surgical clinic visit to Emory University Hospital, Pomenville met by accident â€“ right in the transplant clinic waiting room â€“ many of the individuals whose lives were changed. Soon the patients â€“ recipients and donors â€“ two father and son combinations and Pomenville, the man who would give to anyone â€“ were hugging, shaking hands, and recounting their backgrounds and experiences.
Pomenville and the others, who were all part of what is called a paired kidney exchange, were unwittingly scheduled for appointments within a short period of one another. As one person began recounting the experience, eyes and ears began to focus on the tale being told from across a crowded room.
A chance meeting in a doctors’ waiting room led to a meeting between most of the people involved in the paired kidney exchange.
The Emory Transplant Center created and opened its innovative Paired Donor Kidney Exchange Program in 2009, providing greater hope for patients in need of kidney transplants. According to Kenneth Newell, MD, director of Emory’s living donor program, a paired exchange donation allows healthy individuals to donate a kidney to either a friend, loved one, or even altruistically to a stranger, despite incompatible blood matches. In paired donation, a donor and recipient are matched with another incompatible donor and recipient and the kidneys are exchanged between the pairs.
The procedure is another form of living donor transplantation. Donated kidneys also come from recently deceased donors. While most kidneys from deceased donors function well, studies have shown that a kidney from a living donor, either a blood relative or an unrelated person, provides the greatest chance for long-term success.
“Paired donor exchanges allow us to cast a much wider net to find compatible donors and recipients,” says Newell. “With a paired kidney transplant, one incompatible donor-pair is able to give a healthy kidney to a compatible recipient. In exchange, the second donor-recipient pair will give a compatible kidney to the first donor-recipient pair, making two compatible living donor transplants possible and increasing the potential number of available donor kidneys. This option can help those patients waiting for kidney transplants who have family members or friends willing to be donors and who are medically suitable, but who have an ABO blood type that is incompatible with the recipient’s blood type.”
Because of Pomenvilleâ€™s donation, a 7-year-old boy named Zion was able to receive a lifesaving kidney from an unrelated donor because his dad, Mike, was able to donate. His surgery took place at Children’s Healthcare of Atlanta at Egleston.
And Gerald Smith of Five Points, Ala., would receive his life-saving kidney because his son, Matt, a recent University of Alabama graduate, would donate his to Zion. And finally, 20 year-old Edward Hill of Macon, a young man with a history of health challenges, would also receive his transplant at Childrenâ€™s Healthcare of Atlanta â€“ completing the six-person cycle, although the donor of Edwardâ€™s kidney is still unknown.
And Zion and Matt Smith will not only share a common bond and connection throughout life in the form of a kidney, but something even sweeter that that â€¦ blue Powerade.
â€œIâ€™ve always really enjoyed drinking Powerade, particularly the blue flavor,â€ says Smith. Shortly after Zion awoke from his surgery, he inexplicably began requesting the blue-tinted soft drink too.

Dr. Demuth (pictured far right) was a key player in advancing legislation to call attention to the challenges of food allergies in children. She and several of her patients were on hand to witness Governor Nathan Deal signing a proclamation declaring May 8 to 14 Food Allergy Awareness Week in Georgia.
â€œThe new NIAID guidelines help providers understand food allergies,â€ Demuth says. â€œThey address when we should consider a food allergy and the utility of testing for food allergy. In addition, they address the management of food allergies, including acute reactions and follow-up of individuals with food allergy.â€
The guidelines are comprised of input from a panel of 25 experts and draw the important distinction between food allergies and food intolerances. Food allergies are defined as â€œan adverse health effect arising from a specific immune response hat occurs reproducibly on exposure to a given food.â€ Food intolerances produce an adverse reaction but are likely not related to an immune response.
The most common food allergies are to milk, eggs, peanuts, tree nuts, shellfish, fish and soy. Fortunately, the understanding of food allergies and the best ways to manage them is expanding.
â€œThe gold standard of treatment of food allergies â€“ avoidance â€“ has remained constant throughout the years,â€ Demuth says. â€œThere are new therapies on the horizon such as oral immunotherapy, vaccines and a Chinese herbal extract; however, these therapies are still considered experimental. At the Emory-Childrenâ€™s Center, we are active in research and advocacy in pediatric allergies so that we can bring new treatments to our patients when they are ready for widespread use. We are dedicated solely to the care of children with allergic and immunologic disorders and offer multidisciplinary clinics to offer a specialized level of care.â€
Emory Healthcare is a key player in plans to bring the worldâ€™s most advanced radiation treatment for cancer patients to Georgia.Â Emory Healthcare has signed a letter of intent with Advanced Particle Therapy, LLC, of Minden, Nevada, opening the door to a final exploratory phase for development of The Georgia Proton Treatment Center – Georgiaâ€™s first proton therapy facility.
For certain cancers, proton therapy offers a more precise and aggressive approach to destroying cancerous and non-cancerous tumors, as compared to conventional X-ray radiation. Proton therapy involves the use of a controlled beam of protons to target tumors with precision unavailable in other radiation therapies. According to The National Association for Proton Therapy, the precise delivery of proton energy may limit damage to healthy surrounding tissue, potentially resulting in lower side effects to the patient. This precision also allows for a more effective dose of radiation to be used.
Proton therapy is frequently used in the care of children diagnosed with cancer, as well as in adults who have small, well-defined tumors in organs such as the prostate, brain, head, neck, bladder, lungs, or the spine.Â And research is continuing into its efficacy in other cancers.
The gantry, or supporting structure, of a proton therapy machine.
The closest proton therapy facility to Georgia is the University of Florida Proton Therapy Institute in Jacksonville.Â Currently there are only nine proton therapy centers in the United States, including centers at Massachusetts General Hospital, MD Anderson Cancer Center in Houston and the University of Pennsylvania.
This is an exciting development in our ability to offer not only patients throughout Georgia and the Southeast the widest possible array of treatment options but patients from around the world who can come to Atlanta via the world’s busiest airport, Hartsfield-Jackson International. In addition, we will work to expand its utility and access for patients through collaborative research projects with Georgia Tech and other institutions. Winship physicians will also be able to reach out to their international colleagues and provide direction in how best to study and implement this technology in the care of cancer patients.
Under the letter of intent, Emory Healthcare faculty and staff will provide physician services, medical direction, and other administrative services to the center. Advanced Particle Therapy, through a Special Purpose Company, Georgia Proton Treatment Center, LLC, (GPTC) will design, build, equip and own the center.Â The facility, which will be funded by GPTC, will be approximately 100,000 square feet and is expected to cost approximately $200 million.Â Site selection for the facility is underway, and pending various approvals, groundbreaking is expected in the Spring of 2012.

As parents we hope all babies are born with a healthy start in life, after a full 37 â€“ 40 weeks in the womb. Sadly, every year more than half a million babies are born prematurely in the United States. The rate of premature birth has risen by 30 percent since 1981 according to the March of Dimes. Itâ€™s not clear why some babies are born before full gestation – before their lungs, brains or other organs are fully developed. Thousands donâ€™t live to celebrate their first birthday as a result.
In Georgia more than 400 babies are born too soon each week.Â Dr. William Sexson, a neonatologist and professor of pediatrics at Emory University School of Medicine and March of Dimes Prematurity Campaign Chair witnesses the effects of preterm birth every day.Â He says, â€œPremature birth is the leading cause of infant mortality. Babies born just a few weeks too soon are at increased risk for newborn health complications, such as breathing problems, can face serious health challenges and are at risk of lifelong disabilities.â€
On Saturday April 30, 2011, a legion of more than 10,000 families and business leaders from across Georgia will band together for the March of Dimes annual â€œMarch for Babies.â€ With more than 30 â€œMarch for Babiesâ€ events planned throughout the state, the annual affair is the nationâ€™s oldest walk fundraiser dedicated to preventing premature birth, birth defects and infant mortality.
â€œMarch for Babiesâ€ supports research and educational programs aimed at helping women have healthy babies. Funds raised from the â€œMarch for Babiesâ€ event will support prenatal wellness programs, critical research and community grants, along with local resources such as the Angel II neonatal transport unit at Grady Memorial Hospital.
Most pregnancies last around 40 weeks. Babies born between 37 and 42 completed weeks of pregnancy are called full term. Babies born before 37 completed weeks of pregnancy are called premature. â€œWomen who have hypertension and diabetes are at higher risk to have preterm babies or babies with health problems,â€ says Sexson.
According to the March of Dimes, the most urgent infant health problem in the U.S. today is premature birth. It affects more than half a million babies each year and is the leading cause of newborn death within the first month of life. Last November, the March of Dimes issued a Report Card on Premature Birth, giving the nation a â€œDâ€ and Georgia, the grade of â€œF.â€Â Sexson adds, â€œWe have a long way to go before all babies in America get a healthy start in life and we are committed to working with state health officials, hospitals and health care providers to continue to fight for preemies.â€
The March of Dimes is the leading nonprofit organization with its mission to improve the health of babies by preventing birth defects, premature birth and infant mortality.

A new pilot simulation laboratory at Emory University Hospital Midtown (EUHM) is providing medical students, residents, nursing students and staff with hands-on training to develop, perfect and maintain their skills. Located in the former obstetrics/gynecology (OB/GYN) operating rooms, space that wasnâ€™t currently being utilized, the lab focuses on team building, clinical competencies and research. This is the first simulation lab of its kind at EUHM.
The simulation lab is a joint venture of Emory Healthcare and Emory University School of Medicine, both providing equipment to outfit the lab and a wealth of expertise. Nursing Education, a department within Emory Healthcare, and the Emory School of Medicine have worked together in the development of the simulation lab. Some equipment being used has been donated or given to the hospital for training purposes.
One side of the simulation lab is set-up to train OB/GYN residents and students in deliveries and laparoscopic surgeries, cardiac arrests, mock codes and low volume/high risk procedures.
The other side of the lab focuses on nursing training, nursing education, central-line and intravenous insertion and medication dispensing. It is also being used by nursing for competency validation for new nursing employees and for annual skills assessment of current nursing staff.
Those instrumental in setting up the nursing side of the simulation lab are Sharlene Toney, PhD, RN, executive director, Professional Nursing Practice for Emory Healthcare, and Beth Botheroyd, RN, BSN, MHA/INS, nursing education coordinator for Emory Healthcare.
Toney says the lab is a critical part of the training and education of new nurses and current nursing employees, while also focusing on process improvement activities concentrated on patient safety. Nurses also have the opportunity to test their skills on training simulators and new equipment while in the lab.
Ander describes the lab as a â€œproof of conceptâ€ center, with the small set-up being only the first step in the process. Down the road, he envisions a larger simulation center for all Emory Healthcare employees, Emoryâ€™s School of Medicine and even the community.
Arluck observes as resident Hudson performs an ultrasound on Noelle, the birthing simulator.
Arluck says she uses the simulation lab regularly with OB/GYN residents, teaching them the basics of laparoscopic surgery on a training module and monitor. She also teaches students with the help of an adult-size doll named Noelle, which simulates delivering a baby and going into cardiac arrest.
The simulation lab has also opened the door to medical education research. Emory pulmonary critical care fellow, Jenny Han, MD, is studying to see if a standardized, advanced cardiac life support simulation training has any effect on real patient outcomes in the hospital.
In the future, plans include adding cardiac catheterization simulator capabilities, as well as emergency department and nursing station simulation space.
