Key steps could reduces cases and deaths from rheumatic heart disease in the African Union
Modelling study predicts 30 percent reduction of RHD deaths through early detection, disease management, and cardiac surgery with short-term return on investment
2021-05-11
(Press-News.org) Rheumatic heart disease (RHD) remains a major cause of cardiovascular disease in Africa, even as acute rheumatic fever and RHD have become rare in high-income countries. In a new study led by investigators at Brigham and Women's Hospital, the team modeled the investment case for control of RHD in the African Union (AU) region. Results showed the potential to reduce RHD death by almost a third by increasing coverage of RHD interventions in regions of the AU to 2030, with a high return on investment in both the long and short term. Their results are published in The Lancet Global Health.
"Investing in early detection of rheumatic fever and rheumatic heart disease and providing cardiac surgery to those who need it could have a dramatic effect, saving around 70,000 lives by 2030," said corresponding author Gene Bukhman, MD, PhD, of the Division of Cardiovascular Medicine and Division of Global Health Equity. "Our findings illustrate the importance and high return on investments in the PEN-Plus package of integrated disease management as well as cardiac surgery."
Rheumatic heart disease is the most commonly acquired heart disease in people under age 25 and causes more than 280,000 globally deaths each year. The disease is the result of accumulated damage to the heart valves caused by rheumatic fever. Rheumatic fever is an autoimmune inflammatory reaction to strep throat and frequently occurs in childhood, potentially leading to death or life-long disability.
Rheumatic heart disease can be averted by preventing streptococcal infections or treating them with antibiotics when they do occur. Bukhman and colleagues constructed a model to estimate the health effects, costs, and monetized health gains from increasing coverage of a set of RHD interventions between 2021 and 2030. These interventions include strategies for expanding integrated outpatient care for severe, chronic noncommunicable diseases (NCDs) at district hospitals, encompassing the WHO's Package of Essential NCD Services (PEN-Plus). Examples include preliminary echocardiographic RHD diagnosis, medical treatment of RHD, and postoperative anticoagulation.
The team's modelling approach estimates a 30 percent reduction in death from RHD by increasing coverage of these interventions. The authors note that in the short term, investment in primary prevention would not avert a large number of deaths and would be costly because of the large number of childhood pharyngitis cases. But in the longer term, primary prevention would offer a significant return on investment by preventing costly secondary effects.
"Investing in these measures could avert large amounts of morbidity and mortality and provide returns in economic welfare," said Bukhman. "Our findings indicate that these achievable interventions could accelerate progress towards eliminating RHD in the AU."

Gram-negative bacteria are the bane of health care workers' existence.
They're one of the most dangerous organisms to become infected with--and one of the hardest to treat. But new research from the University of Georgia suggests a component of bacteria's cell walls may hold the key to crushing the antibiotic-resistant microbes.
The reason Gram-negative bacteria are difficult to kill is their double cell membranes, which create an almost impenetrable shield of protection. This shield blocks antibiotics from entering, preventing medications from doing their job of destroying the bacteria. Meanwhile, toxic molecules, known as lipopolysaccharides, on the surface of the bacteria's outer membrane provoke a potentially deadly immune response.

ITHACA, N.Y. - A project based in Tanzania found significant improvements in the diversity of children's diets and food security for households after farmers learned about sustainable crop-growing methods, gender equity, nutrition and climate change from peer mentors.
The farmers experimented with practices introduced to them by Malawian farmers and Tanzanian and American scientists, decided which ones to incorporate within their own farms, and met monthly to share experiences and problem-solve.
The three-year study builds on longer-term research where these environmentally-friendly farming methods, called agroecology, combined with peer-mentoring and farmers collaborating in the process, had successfully improved adult nutrition in Malawi.
"There were a lot of questions about whether ...

May 11, 2021 - For patients seen at a urology clinic, patient satisfaction scores vary by insurance status - with higher scores for patients on Medicare and commercial insurance, but lower scores for those on Medicaid, reports a study in Urology Practice®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.
"Our study adds to previous evidence showing patient satisfaction scores are affected by the type of insurance - not just by the quality of care provided," comments senior author Werner de Riese, MD, PhD, Chair of the Department of Urology of Texas Tech University Health Sciences Center ...

Columbia Engineering/UCLA team is first to demonstrate that phase precession plays a significant role in the human brain, and links not only sequential positions, as seen in animals, but also abstract progression towards specific goals.
New York, NY--May 11, 2021-- For decades the dominant approach to understanding the brain has been to measure how many times individual neurons activate during particular behaviors. In contrast to this "rate code," a more recent hypothesis proposes that neurons signal information by changing the precise timing when they activate. One such timing code, called phase precession, is commonly observed in rodents as they navigate through spaces and is thought to form the ...

WASHINGTON, May 11, 2021 -- Improved ventilation can lower the risk of transmission of the COVID-19 virus, but large numbers of decades-old public school classrooms lack adequate ventilation systems. A systematic modeling study of simple air cleaners using a box fan reported in Physics of Fluids, by AIP Publishing, shows these inexpensive units can greatly decrease the amount of airborne virus in these spaces, if used appropriately.
A low-cost air cleaner can be easily constructed from a cardboard frame topped by an air filter and a box fan. The air filter is placed between the fan and the cardboard base. The fan is oriented so that air is drawn in from the top and forced through ...

PITTSBURGH, May 11, 2021 - Patients with clinically diagnosed neurological symptoms associated with COVID-19 are six times more likely to die in the hospital than those without the neurological complications, according to an interim analysis from the Global Consortium Study of Neurologic Dysfunction in COVID-19 (GCS-NeuroCOVID).
A paper published today in JAMA Network Open presents early results of the global effort to gather information about the incidence, severity and outcomes of neurological manifestations of COVID-19 disease.
"Very early on in the pandemic, it became apparent that a good number of people who were sick enough to be hospitalized also develop neurological problems," said lead author Sherry Chou, ...

Furthering efforts to understand why potentially life-saving statins are so under-prescribed among American patients with heart disease, a new study shows that clinicians are more likely to sign a script for them earlier in the day. The new study by researchers in Penn Medicine's Nudge Unit found that patients with the very first appointments of the day were most likely to have statins prescribed, and the odds progressively fell through the morning and remained low throughout the afternoon. The study was published today in JAMA Network Open.
In recent years, researchers ...

WASHINGTON, May 11, 2021 -- When trauma, illness, or injury causes significant muscle loss, reconstructive procedures for bioengineering functional skeletal muscles can fall short, resulting in permanent impairments.
Finding a synergy in the importance of biochemical signals and topographical cues, researchers from Wake Forest Institute for Regenerative Medicine, Sungkyunkwan University, and Chonnam National University developed an efficient technique for muscle regeneration and functional restoration in injured rats. They describe results from the technique in the journal Applied Physics Reviews, from AIP Publishing.
The group expanded on a method they previously developed using muscle-specific materials derived from ...

To protect their newly formed fragile organs, dark-grown dicotyledonous plants form an apical hook when penetrating through the soil. The apical hook of pifq (pif1 pif3 pif4 pif5) mutant was fully opened, even in complete darkness, suggesting that PIF proteins are required for maintaining the apical hook in the darkness and are involved in regulation of the apical hook opening. But the underlying mechanism for PIF proteins mediated apical hook development remains elusive.
To better understand how PIF proteins affect apical hook development, scientists from the Institute of Botany of the Chinese Academy of Sciences recently investigated their roles ...
