Small vesicles secreted by bacterial cells play a role in recruiting immune cells but surprisingly also might help to protect the pathogens, according to a new study from Carnegie Mellon University and University of Pittsburgh researchers published in mBio. The study is one of the first studies to look at the role of extracellular vesicles released by the pathogen pneumococcus in vivo and may provide a new avenue for vaccine development.
Peripartum cardiomyopathy (PPCM) is a relatively rare but serious complication of pregnancy in which the heart muscle weakens. The source of the condition is unknown, but researchers believe it impacts at least one in 2,000 live births in the US. Greater risk for the disease is associated with preeclampsia, twin or multiple births, older maternal age, some genetic mutations, and ethnicity. Sarah Yahr Tucker reported on PPCM for Popular Science.
It was a nagging mystery: A rare-disease expert at UPMC Children’s Hospital of Pittsburgh had found a successful treatment for two of the deadliest symptoms of one of the more common classes of rare diseases diagnosed by newborn screenings, but one symptom—painful episodes of muscle breakdown that land victims in intensive care—persisted.
Today, the only cure for end-stage liver disease is an organ transplant – an expensive treatment, the demand for which outweighs the supply. Nearly 12,000 people in the U.S. are waiting for a liver as of July 2021.
There is no long-term benefit to surgically placing tympanostomy tubes in a young child’s ears to reduce the rate of recurrent ear infections during the ensuing two years compared with giving oral antibiotics to treat ear infections, a randomized trial led by UPMC Children’s Hospital of Pittsburgh and University of Pittsburgh pediatrician-scientists determined.

Launched recently at UPMC is a novel clinical trial developed by researchers at the University of Pittsburgh School of Medicine to address one of the most important debates during the COVID-19 pandemic: How should doctors decide between quickly adopting new therapies, such as the anti-malarial drug hydroxychloroquine, and waiting until they are tested in longer clinical trials?
University of Pittsburgh School of Medicine scientists announced a potential vaccine against SARS-CoV-2, the new coronavirus causing the COVID-19 pandemic. When tested in mice, the vaccine, delivered through a fingertip-sized patch, produces antibodies specific to SARS-CoV-2 at quantities thought to be sufficient for neutralizing the virus.
As reported by David Templeton for the Pittsburgh Post-Gazette, UPMC researchers are close to completing a blood test to determine immunity against the virus that causes COVID-19. Such a test could certify little or no risk of SARS-CoV-2 infection and identify the so-called “super” people who could serve in the health-care battle against COIVD-19 with little risk to themselves.
Pairing chemotherapy nanodrugs with a nutritional supplement can lessen devastating side-effects while reducing the amount of the expensive drugs needed to treat cancer according to a study from Carnegie Mellon University (CMU) and Taiwan’s National Health Research Institutes (NHRI). In addition, pretreatment with the supplement promotes the production of tumor-killing macrophages, making it a promising complement and supplement to existing chemotherapies.
Auto-brewery syndrome is a rare medical condition in which intoxicating quantities of ethanol are produced by specific types of yeast or bacteria through endogenous fermentation in the digestive system. McGowan Institute for Regenerative Medicine affiliated faculty member Kenichi Tamama, MD, PhD, FCAP, Associate Professor of Pathology at the University of Pittsburgh School of Medicine and Director of the Toxicology Laboratory, and colleagues have reported in the Annals of Internal Medicine the first known case of a woman who urinates alcohol after a never-before-seen condition effectively turned her bladder into a microbrewery.
Although 1 in 7 adults smoke cigarettes the year prior to undergoing weight-loss surgery, nearly all successfully quit at least a month before their operation. However, smoking prevalence steadily climbs to pre-surgery levels within seven years, according to new research led by the University of Pittsburgh Graduate School of Public Health. McGowan Institute for Regenerative Medicine affiliated faculty member Steven Belle, PhD, MScHyg, Professor in the Department of Epidemiology and a Co-Director in the Epidemiology Data Center, Graduate School of Public Health at the University of Pittsburgh, is a co-author on this work.
Mucus is a protective, slimy secretion produced by goblet cells and which lines organs of the respiratory, digestive, and reproductive systems. Slime production is essential to health, and an imbalance can be life-threatening. Patients with diseases such as asthma, chronic obstructive pulmonary disease (COPD), and ulcerative colitis produce too much mucus, often after growing too many goblet cells. Loss of goblet cells can be equally devastating – for instance during cancer, after infection, or injury. The balance of slime creation, amount, and transport is critical, so doctors and medical researchers have long sought the origins of goblet cells and have been eager to control processes that regenerate them and maintain balanced populations.
Sometimes, in order to understand the big picture, you need to start by assessing the smallest of details. It’s a truth that engineers know well — selecting the right materials can mean the success or failure of a given application.
Overweight and obese vitamin D-deficient children who took a relatively high dose of vitamin D every day for six months had lower blood pressure and improved insulin sensitivity than their peers who took a lower dose, according to the results of a UPMC Children’s Hospital of Pittsburgh clinical trial reported in The American Journal of Clinical Nutrition. McGowan Institute for Regenerative Medicine affiliated faculty member Abbe de Vallejo, PhD, Associate Professor of Pediatrics and Immunology in the School of Medicine at the University of Pittsburgh, is a co-author on the study.
Twice as many people as previously believed are dying of sepsis worldwide, according to an analysis published in The Lancet and announced at the Critical Care Reviews annual meeting in Belfast. Among them are a disproportionately high number of children in poor areas.
As a healthy heart ages, it becomes more susceptible to cardiovascular diseases. Though researchers have discovered that relaxin, an insulin-like hormone, suppresses atrial fibrillation (AF), inflammation, and fibrosis in aged rats, the underlying mechanisms of these benefits are still unknown. In a recent Scientific Reports paper, a University of Pittsburgh research team discusses how relaxin interacts with the body’s signaling processes to produce a fundamental mechanism that may have great therapeutic potential.

Surgery can mend congenital heart defects shortly after birth, but those babies will carry a higher risk of heart failure throughout the rest of their lives. Yet, according to a Science Translational Medicine study published by UPMC Children’s Hospital of Pittsburgh researchers, β-blockers could supplement surgery to regenerate infant heart muscle and mitigate the lasting effects of congenital heart disease.
Jenny Blair, writer for PittMed, reports in her article that in April 2019, Pitt began enrolling patients in one of the world’s first trials that combines the electronic health record with a new, efficient, safety-focused randomization process. The system is powered by software created by the Texas-based Berry Consultants. The approach, called REMAP (randomized, embedded, multi-factorial, adaptive platform), may transform the way doctors learn from patients—and how they care for them.
