Head of Cardiac Surgery and Director of the Robotics and Minimally Invasive Surgery Program at the King Faisal Specialist Hospital & Research Centre (KFSHRC) Professor Feras Khaliel was honored at the inaugural day of the Global Health Exhibition (GHE) with the Health Research Excellence: Applied Innovation Award in recognition for his exceptional contributions to advancing research, enhancing knowledge, and fostering innovation in healthcare.
The award also commemorates Khaliel's successful completion of the world’s first robotic heart transplant on a 16-year-old patient suffering from end-stage (Class IV) heart failure, SPA reported.

According to a KFSHRC press release, the center continues to set itself apart by providing innovative specialized healthcare services, particularly through its robotic heart surgery program that has experienced accelerated success since its establishment in 2019.
In its first year, the program performed 105 robotic heart surgeries, rising to 400 and culminating in its leadership in conducting the world’s first fully robotic heart transplant, a pioneering achievement that not only bolsters Saudi Arabia's standing in healthcare but also highlights KFSHRC’s ability to innovate medical practices that enhance treatment outcomes and patient experience.
KFSHRC’s robotic heart surgery program has introduced innovative cardiac procedures, such as robotic multi-valve surgeries and robotic aortic valve replacement. Additionally, it has integrated cutting-edge technologies related to mechanical circulatory support (MCS) systems, including ventricular assist devices (VADs), which aid the heart in pumping blood. These devices serve as either a bridge to heart transplantation or a permanent solution for patients who are not eligible for transplants. This has resulted in significantly improved patient outcomes with survival rates of up to 98%, recovery times reduced by 30%, and a reduction in blood transfusions, mechanical ventilation, and hospital stay by over 50% while cutting costs by 40% compared to traditional methods.
The program is renowned for performing robotic surgeries on a wide age range of patients, from 14 to 78 years old, and for its ability to handle complex, high-risk cases, including patients with severe obesity and those requiring repeat surgeries. Notably, the program excels in performing robotic surgeries on heart patients who have undergone three previous operations, a feat in which the KFSHRC has surpassed its counterparts in American hospitals.

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas.

Paulo de Meo Filho, a postdoctoral researcher at University of California, Davis, is part of an ambitious experiment aiming to develop a pill to transform cow gut bacteria so it emits less or no methane.

While the fossil fuel industry and some natural sources emit methane, cattle farming has become a major climate concern due to the sheer volume of the cows' emissions.

"Almost half of the increase in (global) temperature that we've had so far, it's been because of methane," said Ermias Kebreab, an animal science professor at UC Davis.

Methane, the second largest contributor to climate change after carbon dioxide, breaks down faster than CO2 but is more potent.

"Methane lives in the atmosphere for about 12 years" unlike carbon dioxide which persists for centuries, Kebreab said.

"If you start reducing methane now, we can actually see the effect on the temperature very quickly."

Filho uses the tube to extract liquid from Thing 1's rumen -- the first stomach compartment containing partially digested food.

Using the rumen liquid samples, the scientists are studying the microbes that convert hydrogen into methane, which is not digested by the cow but instead burped out.

A single cow will burp roughly 220 pounds (100 kilograms) of the gas annually.

- 'Social critters' -

Thing 1 and other calves receive a seaweed-supplemented diet to reduce methane production.

Scientists hope to achieve similar results by introducing genetically modified microbes that soak up hydrogen, starving methane-producing bacteria at the source.

However, the team proceeds cautiously.

"We can't just simply cut down methane production by removing" methane-making bacteria, as hydrogen could accumulate to the point of harming the animal, warned Matthias Hess, who runs the UC Davis lab.

"Microbes are kind of social critters. They really like to live together," he said.

"The way they interact and affect each other impacts the overall function of the ecosystem."

Hess's students test different formulas in bioreactors, vessels that reproduce microorganisms' living conditions in a stomach from movements to temperature.

- More productive cows -

The project is being carried out at UC Davis as well as UC Berkeley's Innovative Genomics Institute (IGI).

IGI scientists are trying to identify the right microbe -- the one they hope to genetically alter to supplant methane-producing microbes.

The modified microorganisms will then be tested at UC Davis in the lab and in the animals.

"Not only are we trying to reduce methane emissions, but you also increase the feed efficiency," said Kebreab.

"Hydrogen and methane, they are both energy, and so if you reduce that energy and redirect it to something else... we have a better productivity and lower emissions at the same time."

The ultimate goal is a single-dose treatment administered early in life, since most cattle graze freely and can't receive daily supplements.

The three research teams have been given $70 million and seven years to achieve a breakthrough.

Kebreab has long studied sustainable livestock practices and pushes back against calls to reduce meat consumption to save the planet.

While acknowledging this might work for healthy adults in developed nations, he pointed to countries like Indonesia, where the government is seeking to increase meat and dairy production because 20 percent of children under five suffer from stunted growth.

"We can't tell them to not eat meat," he said.
