Robot performs laparoscopic surgery without guiding hand of a human

February 2, 2022 by Editor Leave a Comment

By Catherine Graham, Johns Hopkins University

In four experiments on pig tissues, the robot excelled at suturing two ends of intestine – one of the most intricate and delicate tasks in abdominal surgery

A robot has performed laparoscopic surgery on the soft tissue of a pig without the guiding hand of a human – a significant step toward fully automated surgery on humans.

Designed by a team of Johns Hopkins University researchers, the Smart Tissue Autonomous Robot, or STAR, is described today in Science Robotics.

Senior author Axel Krieger, an assistant professor of mechanical engineering at Johns Hopkins’ Whiting School of Engineering, says: “Our findings show that we can automate one of the most intricate and delicate tasks in surgery: the reconnection of two ends of an intestine.

Versius receives ‘indication’ extended into thoracic surgery

January 25, 2022 by Editor Leave a Comment

CMR Surgical says its Versius Surgical Robotic System has been “indicated” for thoracics to support surgeons providing minimally invasive surgery to patients undergoing operations in the lungs, thymus and oesophagus.

In medicine, an “indication” is a valid reason to use a certain test, medication, procedure, or surgery.

Following a gradual introduction with specific case and procedure selection, Versius has now been used in both major and minor cases including oesophagomyotomies, lobectomies and thymectomies. [Read more…] about Versius receives ‘indication’ extended into thoracic surgery

Opinion: Predictions about the surgical robots market

January 25, 2022 by Editor Leave a Comment

By Anthony Fernando, CEO and president of Asensus Surgical

Surgery has evolved from open surgery to robotic surgery. Surgical robots can perform complex procedures with geometrical precision, even in anatomical areas that are difficult to reach by human surgeons.

This is resulting in increased demand and adoption of minimally invasive surgeries and is one of the key drivers for the growth of the surgical robotics market.

So here are some predictions that foresee changes in the coming year within the surgical robotics market, telehealth and telesurgery, and augmented intelligence. [Read more…] about Opinion: Predictions about the surgical robots market

Study shows hormone therapy not associated with an increased risk of developing dementia

January 4, 2022 by Editor

New research, led by experts at the University of Nottingham, shows that the use of menopausal hormone therapy (MHT – also known as hormone replacement therapy, HRT) is not linked to an increased risk of developing dementia.

The study, which was led by Dr Yana Vinogradova from the School of Medicine at the University and is published today in the BMJ, provides the most comprehensive and reliable risk estimates to date, and the findings should reassure women in need of MHT.

The large UK study, based on clinical records over many years of women representative of the general population, has shown that this is true regardless of hormone type, dose, or duration of use.

How meditation can help you make fewer mistakes

January 3, 2022 by Farhana Leave a Comment

If you are forgetful or make mistakes when in a hurry, a new study from Michigan State University – the largest of its kind to-date – found that meditation could help you to become less error prone.

The research, published in Brain Sciences, tested how open monitoring meditation – or, meditation that focuses awareness on feelings, thoughts or sensations as they unfold in one’s mind and body – altered brain activity in a way that suggests increased error recognition.

“People’s interest in meditation and mindfulness is outpacing what science can prove in terms of effects and benefits,” said Jeff Lin, MSU psychology doctoral candidate and study co-author. “But it’s amazing to me that we were able to see how one session of a guided meditation can produce changes to brain activity in non-meditators.” [Read more…] about How meditation can help you make fewer mistakes

Secret garden: Drug-resistant pathogen strains meet and evolve on plant bulbs

September 6, 2021 by Editor

Just when we thought it was safe to go to the local garden center, researchers from Japan have discovered that fungicide-resistant strains of a nasty pathogen have been getting up to no good among the tulip bulbs.

In a study published in August in Environmental Microbiology researchers from the University of Tsukuba and Chiba University have revealed that plant bulbs harboring a potentially lethal pathogen also make the perfect lab for evolving fungicide-resistant strains.

The risk associated with fungal infections is increasing, with occurrences of pulmonary aspergillosis (PA), a deadly fungal infection caused by the human pathogen Aspergillus fumigatus, rising globally. Of particular concern are influenza-related PA and Covid-19-related PA, the case numbers of which are growing quickly.

One in ten cardiac arrest patients phoned emergency services the day before

September 6, 2021 by Editor

Difficulty breathing is the most common symptom before cardiac arrest, according to research presented at ESC Congress 2021.

“Breathing problems more frequently preceded cardiac arrest than chest pain,” said study author Mr. Filip Gnesin, a research scholar at North Zealand Hospital, Hillerød, Denmark. “Since difficulty breathing is also a sign of other health conditions, we hope our findings will stimulate further research to help emergency medical dispatchers distinguish between symptoms of a pre-arrest condition versus other medical issues.”

There is limited knowledge on whether there are warning signs for out-of-hospital cardiac arrest. Information on warning signs and early symptoms would enable medical professionals to assess whether a patient is at risk of developing a cardiac arrest and potentially prevent it.

Eating more plant foods may lower heart disease risk in young adults, older women

August 18, 2021 by Editor

Eating more nutritious, plant-based foods is heart-healthy at any age, according to two research studies published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.

In two separate studies analyzing different measures of healthy plant food consumption, researchers found that both young adults and postmenopausal women had fewer heart attacks and were less likely to develop cardiovascular disease when they ate more healthy plant foods.

The American Heart Association Diet and Lifestyle Recommendations suggest an overall healthy dietary pattern that emphasizes a variety of fruits and vegetables, whole grains, low-fat dairy products, skinless poultry and fish, nuts and legumes and non-tropical vegetable oils. It also advises limited consumption of saturated fat, trans fat, sodium, red meat, sweets and sugary drinks.

Metabolism changes with age, just not when you might think

August 18, 2021 by Editor

Most of us remember a time when we could eat anything we wanted and not gain weight. But a new study suggests your metabolism – the rate at which you burn calories – actually peaks much earlier in life, and starts its inevitable decline later than you might guess.

The findings will appear Aug. 12 in the journal Science.

“There are lots of physiological changes that come with growing up and getting older,” said study co-author Herman Pontzer, associate professor of evolutionary anthropology at Duke University. “Think puberty, menopause, other phases of life. What’s weird is that the timing of our ‘metabolic life stages’ doesn’t seem to match those typical milestones.” [Read more…] about Metabolism changes with age, just not when you might think

Deep learning model classifies brain tumors with single MRI scan

August 13, 2021 by Editor

A team of researchers at Washington University School of Medicine have developed a deep learning model that is capable of classifying a brain tumor as one of six common types using a single 3D MRI scan, according to a study published in Radiology: Artificial Intelligence.

“This is the first study to address the most common intracranial tumors and to directly determine the tumor class or the absence of tumor from a 3D MRI volume,” said Satrajit Chakrabarty, M.S., a doctoral student under the direction of Aristeidis Sotiras, Ph.D., and Daniel Marcus, Ph.D., in Mallinckrodt Institute of Radiology’s Computational Imaging Lab at Washington University School of Medicine in St. Louis, Missouri.
