BWH research suggests that certain heart failure patients may extend their life by switching medications.
New Brigham and Women’s Hospital (BWH) research suggests that certain heart failure patients may extend their life by switching medications. The BWH-led study finds that patients with reduced ejection fraction (reduced ability to pump blood from the heart) can expect to live one-and-a-half to two years longer when treated with sacubitril-valsartan instead of enalapril, the current standard of care in heart failure.
Heart failure, the leading cause of hospitalization for Americans over the age of 65, accounts for more than one million hospitalizations in the U.S. each year. About one-half of the nearly six million Americans living with heart failure have the reduced ejection fraction form of the disease, which bears a markedly increased risk for future cardiac events and death.

GERD symptoms may include reflux, difficulty swallowing, coughing, and chest pain.
About 30 to 40 million people in the United States annually complain of frequent heartburn and indigestion, a chronic condition that we describe as gastroesophageal reflux disease (GERD). GERD is characterized by regular reflux – the regurgitation of acid and other stomach content into the esophagus. Other symptoms may include difficulty swallowing, coughing, and chest pain.
Although less common, there are several other types of esophageal disorders, and their symptoms sometimes mimic those of GERD. These conditions may be caused by a lower esophageal sphincter (the muscular ring between the esophagus and the stomach) that fails to relax, a weak esophagus wall, poorly coordinated contractions of the esophagus, a narrowing of the esophagus, or tumors.

Research shows that fall injuries can be prevented through assessment, care plans, and follow-up by primary care providers.
Although falling is a major public health problem among older adults, a growing body of research shows that fall injuries can be prevented through assessment, care plans, and follow-up by primary care providers. Twelve Brigham and Women’s Hospital (BWH) primary care practices are now participating in the largest-ever national research study on fall prevention – Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE).
Falls are all too common among older persons and their results can be devastating. The Centers for Disease Control and Prevention (CDC) reports that in 2013:

Taking testosterone may not improve men’s sexual function or quality of life.
Recent Brigham and Women’s Hospital (BWH) research has found that testosterone use among men doesn’t appear to increase their risk of developing atherosclerosis (hardening of the arteries), a condition that can lead to severe cardiovascular diseases. The same study, however, also found that these same men failed to realize the quality of life benefits that are often the primary goals of testosterone therapy.
Testosterone, a hormone primarily secreted by the testicles, plays a key role not only in male reproductive tissues, but also in muscle growth, bone mass, and metabolism. As men get older, their testosterone levels naturally decline – an average of one percent a year after age 40. In an attempt to counter this natural decline, an increasing number of men over the past decade have turned to testosterone therapy.
Although previous studies aimed at examining rates of adverse cardiovascular events in men taking testosterone have produced conflicting results, concerns remain that testosterone therapy might increase a person’s risk of a heart attack or stroke. BWH investigators developed the Testosterone’s Effects on Atherosclerosis Progression in Aging Men (TEAAM) trial to explore whether there is link between testosterone use and atherosclerosis, a critical risk factor for heart attack and stroke. The three-year study found that administering testosterone to older men (over 60) with low to low normal testosterone levels had no effect on the progression of hardening of the arteries, but also did not significantly improve sexual function or health-related quality of life.

BWH plastic surgeons are offering new breast reconstruction options that use a patient’s own thigh tissue.
Plastic surgeons at Brigham and Women’s Hospital (BWH) are now offering women several new options for natural breast reconstruction after a mastectomy.
These new autologous (own tissue) procedures – PAP (profunda artery perforator), TUG (transverse upper gracilis), and DUG (diagonal upper gracilis) flap reconstruction – are typically reserved for patients who do not have enough tissue in their abdomen for reconstruction or who have already had abdominal surgery. Each option involves taking a complete flap of tissue – including skin, fat, and its accompanying blood supply – from the patient’s own leg and transferring it to the chest to create a new breast.
Women are increasingly turning to these and other types of autologous reconstruction as alternatives to reconstruction with artificial implants. Chief among the reasons for this trend is that flap procedures give women the opportunity to have a reconstructed breast with a natural look and feel that lasts. Because they’re biologic, soft tissue reconstructions evolve with the patient. As a woman loses weight, gains weight, or ages, the reconstructed breast tends to respond in proportion to the rest of the body.

A hydrogel developed by the BWH Biomedical Engineering Division team is strong, flexible, and biocompatible.
Brigham and Women’s Hospital (BWH) bioengineers have a developed a unique hydrogel whose properties could provide significant benefits in wound healing. The BWH Biomedical Engineering Division team, led by biomedical engineer Ali Khademhosseini, PhD, MASc, and chemical engineer Nasim Annabi, PhD, reported their findings in the July 1, 2015, online edition of Advanced Functional Materials.
“Hydrogels are widely used in biomedicine, but currently available materials have limitations,” says Khademhosseini, study senior author and Director of the BWH Biomaterials Innovation Research Center. “Some synthetic gels degrade into toxic chemicals over time, and some natural gels are not strong enough to withstand the flow of arterial blood through them.”
Preclinical testing by the BWH Biomedical Engineering Division researchers, however, shows that their hydrogel is strong, flexible, and biocompatible (harmless to living tissue).

Chelsea Phaneuf and her family.
It’s not every day that a baby is born in the Brigham and Women’s Hospital (BWH) cardiovascular hybrid operating room (OR), but that’s where a multidisciplinary cardiovascular and obstetrics team was at the ready as 29-year-old Chelsea Phaneuf delivered her daughter, Aria, this spring. Chelsea had been admitted to the Shapiro Cardiovascular Center with a failing heart valve about a month before Aria’s arrival.
At the age of 23, an echocardiogram showed that Chelsea’s bicuspid valve had suddenly deteriorated and needed to be replaced. At such a young age, Chelsea was concerned about how the surgery would impact planning for a future family. The daily blood-thinning medication required for patients who undergo a valve replacement with a mechanical device is a risk to a developing fetus. Chelsea, therefore, opted for a biological valve, even though they don’t last as long as a mechanical valve.

Breastfeeding provides benefits to babies and their mothers.
August is National Breastfeeding Month, a good time to talk about the significant short- and long-term benefits that breastfeeding provides to babies and their mothers. This includes lower risk of ear infections, pneumonia, leukemia, and sudden infant death syndrome for babies and lower risk of cardiovascular disease, type 2 diabetes, and ovarian and breast cancers for mothers.
In 1991, the World Health Organization and the United Nations Children’s Fund launched the Baby-friendly Hospital Initiative to establish practices that protect, promote, and support breastfeeding. Brigham and Women’s Hospital is participating in this global effort. Below is an overview of the baby-friendly practices that we follow and promote at the Brigham and Women’s Center for Women and Newborns to help initiate and extend the duration of breastfeeding.

A patient's viral history can be found in a single drop of blood.
Researchers have developed a test that uses a single drop of blood to simultaneously determine which of more than 1,000 different viruses currently infects or previously infected a person.
Using the new method, known as VirScan, researchers from Brigham and Women’s Hospital (BWH) and Harvard Medical School detected an average of 10 viral species per person during their study. The findings, published in Science (June 5, 2015), shed light on the relationship between the vast array of viruses that can infect humans (the human virome) and a person’s immunity. This insight, in turn, has significant implications for our understanding of immunology and patient care.
The research team found the sensitivity and precision of VirScan to be very similar to that of today’s standard blood tests. However, today’s standard blood tests can detect only one pathogen at a time and have not been developed to detect all viruses.

The green areas in the picture above represent a buildup of amyloid in the heart of a patient with senile amyloidosis.
Cardiac amyloidosis is a dangerous and progressive disease that is not yet well understood. As it is quite rare and produces symptoms very similar to other heart diseases, it is often misdiagnosed.
Amyloidosis refers to a group of diseases, caused by deposits of abnormal proteins (amyloid) that affect one or more organ systems in the body. Buildup of amyloid in the heart is known as cardiac amyloidosis, and whether it occurs solely in the heart or in conjunction with other organs, it is the presence of amyloidosis in the heart that determines the severity and outcome of the disease and its treatments.
To promote effective and efficient treatment and a better understanding of the disease among physicians and patients, Brigham and Women’s Hospital established the multidisciplinary Cardiac Amyloidosis Program that draws upon the expertise of some of the country’s leading cardiology specialists. The program is led by noted cardiac amyloidosis expert Rodney H. Falk, MD, who, in the video below, discusses the importance of early diagnosis and the progress being made in caring for patients with the disease.
