Interplay of magnetic fields and gravitation in the Orion Nebula leads to star development

Space bears witness to a constant stream of star births. And whole star clusters are often formed at the same time – and within a comparatively short period. Amelia Stutz and Andrew Gould from the Max Planck Institute for Astronomy in Heidelberg have proposed a new mechanism to explain this quick formation. The researchers have investigated a filament of gas and dust which also includes the well-known Orion nebula.

Hunting for hidden life on worlds orbiting old, red stars

All throughout the universe, there are stars in varying phases and ages. The oldest detected Kepler planets (exoplanets found using NASA's Kepler telescope) are about 11 billion years old, and the planetary diversity suggests that around other stars, such initially frozen worlds could be the size of Earth and could even provide habitable conditions once the star becomes older. Astronomers usually looked at middle-aged stars like our sun, but to find habitable worlds, one needs to look around stars of all ages.

Mysterious happenings around the star KIC 846852

The Kepler satellite was designed to search for Earth-sized planets in the habitable zone of stars by measuring dips in a star's brightness as orbiting planets move across the stellar disc (transits). Its sensitive camera stares at more than 150,000 stars towards the constellations of Cygnus and Lyrae, and so far has found over 5000 exoplanet candidates. But Kepler also monitors the light fluctuations in all the other stars, even dips not caused by transits, and has found some bizarre situations.

A soft actuator using electrically controllable membranes could pave the way for machines that are no danger to humans

In interacting with humans, robots must first and foremost be safe. If a household robot, for example, encounters a human, it should not continue its movements regardless, but rather give way in case of doubt. Researchers at the Max Planck Institute for Intelligent Systems in Stuttgart are now presenting a motion system—a so-called elastic actuator—that is compliant and can be integrated in robots thanks to its space-saving design. The actuator works with hyperelastic membranes that surround air-filled chambers. The volume of the chambers can be controlled by means of an electric field at the membrane. To date, elastic actuators that exert a force by stretching air-filled chambers have always required connection to pumps and compressors to work. A soft actuator such as the one developed by the Stuttgart-based team means that such bulky payloads or tethers may now be superfluous.

Binocular vision-based UAVs autonomous aerial refueling platform—pilots are no longer needed

Unmanned aerial vehicles (UAVs) are invaluable in today's military and civilian initiatives. However, most unmanned systems are being designed to execute the long-running mission. Thus, it is necessary for UAVs to return to the base for refueling. Autonomous aerial refueling (AAR) is therefore an important capability for the future deployment of UAVs. Vision-based sensor and navigation system are widely used in AAR, while experiments are done for both probe-and-drogue refueling system and boom approaches.

An energy strategy that can take the heat

Long-acting cardioplegia solution results in better outcomes for pediatric heart surgery patients

The myocardium (muscular tissue) of the pediatric heart exhibits structural and functional differences as compared to adult myocardium. As a result, different myocardial protection techniques have been developed for clinical use in neonates, infants, and children undergoing cardiac surgery. In a presentation at the 96th AATS Annual Meeting, a team of cardiac surgeons presents the results of a prospective randomized clinical trial of pediatric surgery patients, comparing a new type of long-acting cardioplegia (heart stopping) solution to the standard short-acting agent that requires repeated dosing during surgery. On many of the key parameters measured, such as length of time needed for surgery and interruption of blood flow, the results favored the long-acting del Nido cardioplegic solution.

Older Patients with atrial fibrillation at greater risk for post-op tricuspid regurgitation after mitral valve repair

Tricuspid regurgitation (TR) occurs when the heart's tricuspid valve leaks, allowing blood to flow back from the right ventricle to the right atrium. TR can be secondary to disorders of left-sided heart valves (mitral or aortic). At the 96th AATS Annual Meeting, investigators present the results of a long-term study of patients who underwent mitral valve (MV) repair. They found that although newly developed TR after MV repair was rare, the risk could increase in older patients with atrial fibrillation and impaired heart function.

National trends in opioid related overdoses are being felt across every part of the medical system, including the country's intensive care units. ICU admissions related to opioid overdoses are steadily increasing, and opioid overdose-related ICU deaths have nearly doubled since 2009. New research from Boston's Beth Israel Deaconess Medical Center, University of Chicago, and Vizient, Inc., presented at the ATS 2016 International Conference shows the strain America's opioid crisis is putting on ICUs and the critical care teams who care for these patients and calls attention to efforts needed to meet the demands of this expanding population.

Risk factors identified for readmission to hospital following esophagectomy

Esophagectomy is a major surgical procedure associated with significant complications with up to 1 in 5 patients readmitted following hospital discharge. These unplanned readmissions are an important problem as they negatively impact patient care and, in the future, may have implications for reimbursement through the Hospital Readmissions Reduction program. Identification of patients at risk of readmission is critical for enabling centers to develop strategies to reduce unplanned readmissions. Some readmission events may be unavoidable, but others, often due to postoperative complications, are not. The key to reducing the burden on patients and healthcare resources is to identify potentially preventable readmissions and institute measures to mitigate them.

Cancer risk perception could lead to adverse health outcomes among women

According to recent studies, the U.S. has a disadvantage in women's life expectancy compared to peer countries despite high rates of health screenings such as mammography and popular national awareness campaigns. Recently, researchers at the University of Missouri examined the perceptions of risk among females and found that minority and less educated women believe that breast cancer, rather than heart disease, is the more common killer. Based on these findings, they recommend that health care providers should incorporate healthier lifestyle strategies for heart disease with messages for improved breast health to greater impact disease outcomes.

Implantation of rapid deployment aortic valve found to be durable, safe, and effective

When replacing a defective aortic valve with a new one, restoring function is the first priority. However, variables such as durability, length of surgery, duration of heart stoppage, size of the surgical incision, postoperative pain, and complications are other important considerations. In a presentation at the 96th AATS Annual Meeting, the results of the TRANSFORM Trial, a large multicenter study evaluating the safety and performance of an investigational rapid deployment aortic valve replacement (RDAVR) system for patients with severe aortic stenosis, was presented. The results show that compared to more conventional methods, this system was associated with excellent one-year survival, reduced the duration of heart stoppage, and was associated with clinically acceptable postoperative complication rates.

Is laparoscopic repair of ventral hernia the ideal approach for all patients?

Laparascopic repair of ventral hernias has advanced and overcome many challenges during the past two decades, and patients who are obese, diabetic, and have a hernia no larger than 10 cm in width are best suited for this evolving minimally invasive approach. New types of mesh to close the defect are in development, and better long-term studies are needed to define best practices and determine ideal indications of this technique, according to an article in Journal of Laparoendoscopic & Advanced Surgical Techniques (JLAST), a peer-reviewed journal published by Mary Ann Liebert, Inc., publishers. The article is available free to download on the JLAST website until June 16, 2016.

Stage IIIA non-small cell lung cancer survival rates improved when care includes four specific quality measures

Current guidelines from the National Comprehensive Cancer Network (NCCN) and American College of Chest Physicians (ACCP) recommend that operable patients with clinical Stage IIIA non-small cell lung cancer (NSCLC) should receive induction chemotherapy (with or without concurrent radiotherapy) followed by resection if there is no apparent progression of disease. While four quality measures have been identified as associated with improved overall survival, until now it has been unclear to what extent patients are actually receiving each of these measures as part of their care. A presentation at the 96th AATS Annual Meeting clearly demonstrates that survival rates increase as more quality measures are incorporated into patient care - but only 13% of eligible patients actually received all four measures.

Minimally invasive tendon repair technique supports knee movement sooner after surgery

Quadriceps tendon ruptures are disabling knee injuries that typically occur in adults ages 40 and older. Obesity, illness or traumatic injuries can cause these types of injuries. Most tendon ruptures require surgery, and the current gold-standard technique for repairing these ruptures is transosseous (literally, through-the-bone) tunnel repair, a lengthy, technically demanding procedure. In a new study, University of Missouri researchers have found that suture anchors, a less-invasive repair technique, responded better to strength-testing after the surgery, supporting more movement in the knee earlier in the recovery process.

New implantable VAD for severe heart failure in kids shows encouraging results in sheep

The number of children with severe heart failure is increasing. Over the last decade, ventricular assist devices (VADs) have become the standard of care in the management of severe heart failure. In adults, implantable VADs (i.e. pumps placed within the chest) are used exclusively, due in part to favorable risk profiles and, more importantly, the opportunity for home discharge and outpatient management. By contrast, no implantable VADs designed specifically for small children (approximately 5 to 20 kg) are currently available. The result is that the vast majority of pediatric patients with severe heart failure are currently managed with paracorporeal VADs (i.e. pumps sitting outside the body), which in general are associated with higher risk profiles and require hospital management. In a presentation at the 96th AATS Annual Meeting, researchers describe testing of a pediatric-specific implantable VAD in living animals.

MSK surgeons present strategies for increasing survival in soft tissue sarcoma patients

Up to 50% of patients with soft tissue sarcoma (STS) develop lung metastases. Effective systemic therapies for metastatic STS are currently limited; when possible, surgical removal of the lung metastases (known as pulmonary metastasectomy, PM) is the preferred treatment. However, guidelines for the performance of PM for STS do not exist and decisions to operate are often made on an individual basis. In a presentation at the 96th AATS Annual Meeting, researchers from Memorial Sloan Kettering Cancer Center share the results of their experience with more than 500 patients with pulmonary metastases from STS and describe prognostic factors associated with improved survival.
