Emma Kahn, a longtime volunteer at UC San Francisco Medical Center, brightens the day of patient Robert Watson.

“How might we all maintain well-being and thrive as we age?”

This question was posed in a worldwide OpenIDEO/Mayo Clinic Challenge that produced 133 concepts and eventually six winners, including a team from UC San Francisco.

UCSF’s team ranked in the top three in terms of popularity and number of views to its proposal.

“Nine medical education staff decided to take on the challenge and over the course of two months they participated in a worldwide community who were inspiring, ideating, prototyping and refining solutions to the challenge,” said Kevin Souza, M.S., associate dean for medical education at UCSF. “Eventually the team coalesced around the solution titled ‘More than just a doctor’s visit, a bridge to wellness,’ which proposes a different approach to the learner-patient health care visit.”

The nine members of the UCSF group, all from the medical education staff in the School of Medicine, envisioned reshaping a doctor’s visit by creating a wellness team. Consisting of medical students and senior volunteers, the team members would serve as coaches for aging community members in inpatient settings, where they could talk about everything from prevention and nutrition to depression and other mental or emotional issues.

“My overall goal is to empower the staff to look at the system around them,” Souza said. “For example, if you’re at the front desk at the Student Affairs Center, how could it be better? We started training our staff in these skills, and I started looking for ways to practice them. This challenge came up and it was health-related, which fit beautifully with our focus.”

Souza invited his entire staff to participate if they wished. The nine members of the final team brought diverse skills and backgrounds. Their work is also directly tied into the UCSF Bridges Curriculum now being designed, which will allow medical students to learn systems improvement skills and work on quality improvement projects.

Guide to buying sunglasses

Berkeley Wellness offers tips for what to look for in sunglasses.

Woman wearing sunglassesMany people choose sunglasses by how they look and feel. But the most important feature to consider is how well they shield your eyes from ultraviolet rays (high-frequency invisible energy emitted by the sun), as well as blue light (high-frequency visible light).

Chronic ultraviolet (UV) exposure is implicated in a range of eye conditions, including cataracts, benign growths on the surface of the eye, skin cancer on the eyelid and around the eyes and even melanoma of the eye itself. Blue light is particularly damaging to internal eye tissues and over time may permanently damage the retina, leading to macular degeneration.

Sun damage is cumulative, so the more time you spend outdoors with your eyes unprotected, the greater your lifetime risk. The good news is that it’s not hard to find affordable sunglasses that are fashion-forward and protective.

Can wellness cure?

UCSF scientists prove benefits of living a healthy lifestyle.

Should anyone doubt America’s mounting health crisis, a new report from the National Research Council and Institute of Medicine makes it crystal clear. On average, Americans of all ages die sooner and experience higher rates of disease than people in 16 other rich countries.

Even advantaged Americans with health insurance, college educations, and higher incomes appear to be sicker than their peers in other wealthy nations. While the reasons are varied and potential solutions complex, experts at UC San Francisco are proving that your mother’s admonishments – eat your vegetables, get off your duff, quiet down – may be just the prescription this nation needs.

Turns out, a healthy lifestyle can not only keep illness at bay, but it may even stop a disease like cancer dead in its tracks.

UC San Francisco has long led the way in demonstrating the positive effects of living a healthy lifestyle. Read more about studies by UCSF researchers such as Dean Ornish, Peter Carroll, Nobel laureate Elizabeth Blackburn and Elissa Epel.

Getting help to live tobacco-free, one day at a time

UC Riverside offers services to help quit smoking as UC system going tobacco free by January.

Smoking cessation expert V.J. Sleight (left) and UC Riverside Wellness Program Coordinator Julie Chobdee (right) with Bob Slater, the senior superintendent for building maintenance and operations, who is working to give up smoking after having the habit for 40 years.

About 40 years ago, one of Bob Slater’s friends offered him a cigarette. Smoking was the “cool thing to do”, so he succumbed to “peer pressure” and smoked it. That cigarette was the first step on a pack-a-day habit that lasted four decades.

Now in 2013, Slater, the senior superintendent for building maintenance and operations at UC Riverside, is enlisting the help of his family, friends, co-workers and Mayo Clinic-trained tobacco cessation expert V.J. Sleight to help him break the habit. With the entire University of California system going smoke and tobacco free on Jan. 2, 2014, Slater is one of many UCR staff, students and faculty who are taking advantage of services offered through campus wellness programs to help them kick the habit. Estimates are that as many as 70 percent of smokers want to stop using tobacco, but are not ready to do so.

For Slater, while the campus’ pending ban provided some motivation, he made the decision to give up tobacco for himself and his family. He smoked his last cigarette on April 23.

“My wife, Karen, had wished that I would quit smoking for some time,” he said. “I finally realized that smoking negatively affects my daily health would certainly shorten my life or quality of life which would affect my children, grandchildren, loved ones and friends. I’ve only been off cigarettes for three weeks and I already feel better and can taste and smell things differently.”

“As an ex-smoker V.J. has helped me tremendously to understand the symptoms of nicotine withdrawal and educated me on many little tricks to get by the initial challenges in the first two weeks,” he added.

Julie Chobdee, the UCR Wellness Program coordinator, explained that the university partnered with Sleight because it is important to support employees and students who want to stop using tobacco.

“Smoking cessation education and support can significantly improve compliance and the UC is committed to supporting all students, staff and faculty who wish to stop using tobacco products,” Chobdee said, adding that assistance is available through the Campus Health Center and The Well, in addition to the Faculty/Staff Wellness Program.

How to manage low back pain

Berkeley Wellness offers insight into the second most common medical complaint.

Four out of every five people will experience low back pain at some point in their lives, and many will contend with repeated episodes of debilitating pain on and off, sometimes for years. Low back pain is the second most common medical complaint after headache. It’s a leading cause of doctor visits and missed days from work, second only to the common cold.

So what should you do about low back pain? Find out more in an interview with William Pereira, M.D., M.P.H., adapted from the UC Berkeley Wellness Report “How to Manage Back Pain,” of which he is the co-author. Pereira is associate chair of the editorial board of the UC Berkeley Wellness Letter and is board-certified in occupational and environmental medicine. He has more than 30 years of clinical experience in occupational, preventive, primary care, physical and emergency medicine.

Emotional-health connection not limited to industrialized nations

UC Irvine study finds phenomenon more marked in developing countries.

Sarah Pressman, UC Irvine

Positive emotions are known to play a role in physical well-being, and stress is strongly linked to poor health, but is this strictly a “First World” phenomenon? In developing nations, is the fulfillment of basic needs more critical to health than how one feels? A UC Irvine researcher has found that emotions do affect health around the world and may, in fact, be more important to wellness in low-income countries.

The study, which appears online in Psychological Science, is the first to examine the emotion-health connection in a representative sample of 150,000 people in 142 countries. Previous research on the topic has been limited to industrialized nations.

“We wondered whether the fact that emotions make a difference in our health is simply because we have the luxury of letting them,” said Sarah Pressman, assistant professor of psychology & social behavior and the study’s lead author. “We wanted to assess the impact of emotions on health in places where people face famine, homelessness and serious safety concerns that might be more critical correlates of wellness.”

Against expectations, researchers found that the link between positive emotions (enjoyment, love, happiness) and health is stronger in countries with a weaker gross domestic product. In fact, the association increased as GDP decreased, according to Pressman.

People in Malawi, which has a per capita GDP of $900, show a more robust connection between positive emotions and health than residents of the U.S., which has a per capita GDP of $49,800.

“A hostile American with hypertension can take blood pressure-lowering medication. A Malawian cannot,” Pressman said. “Medical interventions might lower the impact of emotions on health.”

Using data from the Gallup World Poll, researchers noted whether participants had reported experiencing enjoyment, love, happiness, worry, sadness, stress, boredom, depression or anger during the previous day. They also measured physical health and the degree to which subjects’ basic needs were met. Security was assessed by asking if participants felt safe walking alone at night or whether they had been robbed, assaulted or mugged.

“We hope that by showing that this phenomenon is prevalent and stronger than some factors considered critical to wellness, more attention will be drawn to the importance of studying both positive and negative emotions,” Pressman said.

She co-authored the study with Shane Lopez of the Gallup Organization and Matthew Gallagher of Boston University.

How good are generic drugs?

The Berkeley Wellness Letter explores the issue.

In the last few years, many blockbuster prescription medications — including some leading statins, antidepressants and drugs for hypertension, reflux disease and osteoporosis — have become available as generics, and more brands will soon join the list. About three-quarters of prescriptions in the U.S. are now for generic drugs. This has trimmed hundreds of billions of dollars from the nation’s rising health care costs and, by allowing more people to afford the medication they need, has undoubtedly saved countless lives.

The government (notably the Food and Drug Administration, or FDA, which regulates drugs), insurers and virtually all medical groups insist that generics are as effective and safe as the original products. Still, some people believe that cheaper drugs can’t be as good as the brand names and fear that switching to a generic is risky.

The FDA (as well as Health Canada) requires generics to measure up to the originals in terms of strength, quality, purity and safety. Generics must deliver to the body the same amount of active ingredient, at very close to the same rate, as their brand-name counterparts — this is called bioequivalence. (Some generics are made by the same manufacturers that make the branded drugs and are then sold to the generics companies, in which case the drugs are truly identical.) The FDA requires manufacturers to do bioequivalence testing of generics, though not necessarily of all formulations; it rarely does the testing itself. Complicating matters is the fact that generics for a specific drug are typically made by several companies.

Even though brand name and generic drugs have the same active ingredient, the drugs can differ in shape, color and inactive ingredients, such as preservatives and fillers. A generic tablet may be harder or softer than the original, which could affect how quickly it dissolves and is absorbed. And a generic of a time-release drug may employ a different mechanism to gradually release the active ingredient.

For these and other reasons, generics may not be the exact bioequivalent of the originals. The FDA does allow some leeway for generics (as well as for differences among brand-name drugs). Its reviews of thousands of studies have found that the absorption of generics differs from the brand names by only 3 to 4 percent, on average, comparable to differences among batches of many brand-name drugs. Such a small difference won’t matter for most drugs, but for some it may reduce effectiveness and/or safety. Moreover, that “average” difference disguises a wider range of variability in bioequivalence.

Watching your weight

UC brown bag event offers nutritional tips.

Susan Algert

>>Listen to an audio recording of the event

By Alec Rosenberg

If you want to maintain a healthy weight, UC Cooperative Extension nutrition advisor Susan Algert, Ph.D., R.D., has some sage tips: snack wisely; eat more fruits and vegetables; keep a food record and stay active.

Algert shared the latest dietary advice from the U.S. departments of Agriculture and Health and Human Services with UC Office of the President employees at a brown bag event Wednesday in Oakland co-hosted by UC Health and UC Agriculture and Natural Resources.

“How many of you really watch your weight?” Algert asked the audience. “No matter how hard we try, it seems to creep up a little bit as we get older.”

Indeed, studies have shown that adults gain an average of around a pound a year. How that happens might surprise you, according to Algert, a nutrition advisor with UC Cooperative Extension of Santa Clara, San Mateo and San Francisco counties.

Research from a large representative study of women in the U.S. shows that as little as an extra 13 calories per day – the equivalent of consuming one extra ounce of soda and walking one minute less – has led to an average weight gain of 35 pounds in 28 years since the 1970s. Eating an extra chocolate chip cookie every day for life? Expect to gain 6 pounds.

“People always say, ‘I don’t know how I gained it.’ We don’t usually gain weight by eating fruits and vegetables. It’s all those goodies loaded with fat, sugar and salt that we snack on,” said Algert, who previously was a clinical research nutritionist with UC San Diego School of Medicine’s Warren Celiac Center.

Snacking is the worst culprit, Algert said. Instead of soda and chips, try fruits and vegetables, nonfat yogurt, or nuts, she said. If you drink sugar-free soda, limit yourself to one or two cans a day. Better yet, drink water flavored with cucumber or lemon.

People also need to be careful when eating out. She pointed to examples such as Cheesecake Factory’s Bistro Shrimp Pasta, which has more than 3,000 calories – 1 ½ times the recommended daily caloric intake for an average adult – and Smoothie King’s 40-ounce Peanut Power Plus Grape smoothie, which contains about a cup of sugar and nearly 1,500 calories.

“If you eat out more than a couple of times a week, you’re in trouble because you’re likely consuming more fat and calories than you realize,” Algert said. Other key factors that lead to weight gain are decreased physical activity, increased television viewing, increased alcohol intake and poor sleep.

So what should you do?

Algert said two reliable sources of nutrition information are the U.S. Department of Agriculture’s MyPlate dietary guidelines and the U.S. Department of Health and Human Services’ DASH (Dietary Approaches to Stop Hypertension) eating plan, which focuses on healthy fat, fruits, vegetables and reduced-fat dairy and limits sweets to no more than five servings a week. Also, UC offers a variety of nutrition education, including the CalFresh program, which reaches 140,000 Californians a year.

Algert encouraged people to buy fresh, local food. “Vote with your fork,” she said. “Don’t buy junk food. Support a healthy food environment by going to the community gardens and by going to the farmers markets.”

Another suggestion is to keep a food record — track what you eat, when you eat and what your mood is (do you eat ice cream when you are stressed?).

Most of all, keep trying. Even the experts wrestle with their weight.

“I am trying to increase my fruit and vegetable intake to the eight-10 per day recommended in the DASH diet. I have a bit of a sweet tooth. It is a challenge in today’s food environment!” Algert said.

UC WorkStrong helps employees with repeat injuries get healthier

Program taking shape on UC campuses such as UCLA.

UCLA's Danny Flores, in a warehouse at University Apartments South where he works, shed 20 pounds so far through the WorkStrong program.

Danny Flores’ New Year’s resolution has a ring of familiarity to many of us: He’s determined to eat healthier, exercise and shed 10 pounds. Fortunately for Flores, a 16-year employee with UCLA Housing and Hospitality Services, there’s a high probability that he will actually reach his goal.

That’s because Flores has gotten one-on-one help from a personal-fitness trainer, a registered dietitian and a motivational-wellness coach to put him on the road to better health. And he’s now working out at a campus gym on a free pass that’s good through April.

A special 12-week program — offered to him through the combined efforts of UC’s Office of Insurance and Risk Management, UCLA’s Occupational Health Facility and UCLA Recreation and funded by UCLA’s Office of Risk Management — has empowered him to get healthy by giving him access to UCLA’s personal coaches in health, fitness and behavior modification. And it’s paid off — he’s already taken 20 pounds off his 5-foot-8 frame over the last three months.

“Having different people right there to motivate you … it’s an unbelievable support group,” said Flores. “Honestly, if it was just me doing this on my own, I would have given up. But if I make a commitment to someone, I will come through. Obligate me, make me responsible for something, and I will come through.”

Flores is one of a small pool of UCLA employees who have been invited to join the WorkStrong program, which got under way at UCLA last April but really picked up steam over the summer. So far, 46 UCLA employees have participated and eight have completed it to date. The program was launched systemwide by the UC Office of the President to help those employees who are most prone to workplace injuries — people who have been injured on the job at least twice within a 24-month period.

Run on the Westwood campus out of the Occupational and Employee Health Facility on the sixth floor of the Center for the Health Sciences, WorkStrong is designed to help employees improve their overall health and thereby cut their risk for reinjury, said Dr. T. Warner Hudson, director of the facility.

“Many people join an employer when they are young, lean and healthy with good blood pressure and good weight,” the physician said. “But over time, people can gradually pick up weight, get high blood pressure and diabetes, develop sore backs and knees, and maybe even have heart attacks and strokes. But people can turn this around. The Centers for Disease Control and Prevention have data that show that about 75 percent of chronic health conditions can be avoided if people adopt a healthier lifestyle.”

To find out whether this holistic approach works, UC San Francisco did a pilot study with 73 employees who had been injured and gave them access to personal trainers, dietitians, smoking-cessation programs and behavior-modification coaches. After four years, researchers found only one of the participants had been reinjured.

Arsenic & old rice

Wellness Letter: Chronic arsenic exposure from rice, other foods poses long-term health risks.

Bowls of rice and grainsArsenic, a naturally occurring element and industrial byproduct, poses a significant health risk to millions of people worldwide when it leaches into drinking water. It’s highly poisonous at high doses, but chronic exposure to lower levels increases the risk of bladder, lung and skin cancer, as well as infertility and possibly diabetes, heart disease and other conditions.

Though this is often thought of as a major problem only in developing countries, such as Bangladesh, the U.S. has arsenic problems of its own. In fact, it’s estimated that over two million Americans drink water from private wells that have high arsenic concentrations. This past year, arsenic made headlines on several occasions for its presence in rice and other foods, too.

Against the grain

In September, Consumer Reports released results of its analysis of 223 rice samples, which included white and brown, organic and conventionally grown, domestic and imported, and brand-name and store-brand rices. It also tested rice-based products, such as rice cereals, beverages, pasta, flour, and crackers. Virtually all were found to contain both inorganic arsenic (a known human carcinogen) and organic arsenic (considered less harmful but still of concern) — many at “worrisome levels.” In this context, the term “organic” refers to the element’s chemistry, not whether the food was grown organically.

There were wide variations in the findings — after all, there are many different kinds of rice grown all over the world and under different conditions. But some trends emerged: White rice from Arkansas, Louisiana, Missouri and Texas (where most U.S. rice comes from) had more total and inorganic arsenic than rice grown elsewhere (including California, India and Thailand). And within the same brands, brown rice had more arsenic than white rice (some arsenic is removed when the grain’s outer layer is stripped during processing to make white rice). Preliminary results from an FDA analysis of 200 rice products, also released in September, were consistent with those of Consumer Reports; results from about a thousand more samples are due out shortly.

Cold supplements, from Airborne to zinc

UC Berkeley Wellness Letter examines how effective these supplements are.

A cure or preventive for the common cold has been a holy grail for medical researchers and drug companies. So far nothing has worked — medications for colds simply relieve some symptoms temporarily, at best. No wonder, then, that people are tempted by the cold-fighting and/or immunity-boosting claims made for many dietary supplements. Do any of them stand up to scientific scrutiny?

Some supplements with purported cold-fighting ability are single nutrients or herbs. Others try to impress with a mind-numbing list of ingredients.


The best known supplement that throws the kitchen sink at colds, Airborne contains vitamins (A, C, E), minerals (magnesium, zinc and selenium) and echinacea, ginger and a bouquet of other herbs. In 2008, the Federal Trade Commission accused the company of making unproven claims about curing and preventing colds and flu; the company had to pay a $30 million settlement. So now the ads and packages merely say that Airborne “supports” the immune system (wink, wink).

Some of the ingredients in Airborne and other formulas have been tested in controlled studies, with inconsistent results. But there have been no clinical trials testing the specific formulas, at least none that have been published in peer-reviewed journals.

Our take: Forget about Airborne and similar formulas. They’re a waste of money. And if taken often, Airborne may weaken bones because of its relatively high level of vitamin A.


Lab research suggests that this herbal remedy, usually Echinacea purpurea, can stimulate the immune system and have direct antiviral and anti-inflammatory effects. But human studies on echinacea’s effect on colds or immunity have had inconsistent results. Commercial preparations vary widely in the species and the parts of the plants used, making it hard to compare results. Two large, well-designed studies in 2010 and 2011 found that echinacea was not better than a placebo at preventing colds or reducing their severity.

Our take: The claims about echinacea for colds have yet to be supported by solid research.


Despite a common belief that garlic can prevent colds, there has been remarkably little human research on this. This year a study in Clinical Nutrition found that an aged garlic extract taken for three months did not reduce the incidence of colds or flu, but did reduce their severity somewhat when they did occur.

Our take: Garlic is no more likely to keep away colds than to repel vampires, unless you eat it raw and the smell makes cold sufferers stay away from you.


Like echinacea, this herbal cure-all can affect certain aspects of the immune system, though it’s not clear what practical significance this has. Commercial preparations vary widely. A few preliminary studies suggest that Cold-fX, a patented standardized extract of North American ginseng, may help reduce the frequency and severity of colds (and flu) when taken twice daily throughout the winter, a claim allowed by Health Canada, which functions like the our FDA. There’s no evidence that it can provide relief once you have symptoms, though marketers have sometimes claimed or strongly suggested this. In the U.S., Cold-fX is available only online.

Our take: Cold-fX may help against colds and flu when taken daily for several months. But at about $30 a month, we don’t think it’s worth it. Moreover, long-term use raises questions about possible interactions with drugs (such as the blood thinner warfarin) and potential problems in people with certain health conditions (such as autoimmune disorders).


These supplements contain “friendly” bacteria that are supposed to strengthen immunity, among other proposed benefits. But studies on whether they can curb colds and other respiratory infections have been inconsistent. One problem is that supplements use countless different strains and doses. In 2011, the Cochrane Collaboration, which evaluates medical research, concluded that probiotics may help prevent acute respiratory infections, though there were limitations in the studies and no data for older people.

Our take: We don’t recommend probiotic supplements for cold prevention. We’ll discuss probiotics in an upcoming issue.

Vitamin C

This gained popularity in the 1970s when Linus Pauling claimed it could prevent and alleviate colds. However, numerous studies have failed to confirm any benefit. According to a Cochrane Collaboration review in 2010, vitamin C supplements do not prevent colds, except perhaps in people exposed to severe physical stress, such as marathon runners and skiers. And research on the vitamin’s potential role in reducing the severity and/or duration of cold symptoms when taken at their onset has yielded mixed results.

Our take: The tide has turned against vitamin C. If there were a significant benefit, it wouldn’t be so hard to prove.

Vitamin D

Some experts believe that vitamin D can help protect against respiratory infections, in part because it plays key roles in the immune system. Many studies have found that people with low blood levels of D are at increased risk for colds and other upper respiratory tract infections.

But the few clinical trials have had mostly disappointing results. For instance, a study from Winthrop Hospital in New York in 2009 found that 2,000 IU of vitamin D a day, taken for 12 weeks, did not reduce the risk of upper respiratory tract infections. And in a study from New Zealand in the Journal of the American Medical Association in October, monthly megadoses of D (100,000 IU), taken for 18 months, also did not reduce the risk. The great majority of subjects in both studies started with sufficient blood levels of D, however, so it’s not known if people who were deficient would have benefited.

Our take: There are some good reasons to take vitamin D supplements, notably for bone health — but not for cold prevention. More on vitamin D.


This mineral is also essential for immunity. In lab studies, large amounts of zinc can block cold viruses from adhering to the nasal lining and/or replicating themselves. Earlier this year a Cochrane Collaboration review concluded that, compared to a placebo, zinc lozenges can shorten colds by about a day and reduce their severity somewhat, particularly when started within 24 hours of the first symptoms, though not all the studies found a benefit. Another 2012 research review, in the Canadian Medical Association Journal, came to similar conclusions. There is no good research showing that zinc will prevent colds, however.

Our take: Because of possible side ef­­fects (nausea, diarrhea, cramps and a bad taste in the mouth) and questions about the effectiveness of some formulations, the Cochrane authors concluded that zinc lozenges, taken during the first day of symptoms, are “advised with caution.” We agree. Prolonged use of high doses of zinc can interfere with the absorption of copper and actually impair immune function. Don’t use any zinc product that’s applied directly in the nose; this can damage the sense of smell, possibly permanently.

Bottom line

There’s no convincing evidence that any supplement can prevent or treat colds. “Cold remedies,” including many over-the-counter drugs, may well make you feel better, since they have a strong placebo effect. That is, if you expect or hope that a remedy is going to help, there’s a fair chance it will, whether it contains vitamins, herbs or just plain old sugar. And, of course, remedies may seem to work because colds go away on their own. Though we don’t recommend them, it probably can’t hurt to take such products when you feel a cold coming on, but taking them throughout cold season, as is sometimes recommended, increases the risk of adverse effects.
