The Texas high-speed train that plans to zip between Houston and Dallas still has some obstacles to plow through, but the project now has a builder at least.

Texas Central, the developer of the Texas Bullet Train, has signed a contract with Salini Impregilo, an Italian construction company and one of the largest civil engineering contractors in the world, and its American subsidiary, Lane Construction.

"This agreement brings us one step closer to beginning construction of the civil infrastructure segments of the project," said Texas Central CEO Carlos F. Aguilar, in a release.

The train still can't move forward because it doesn't own all of the land necessary for the route.

But if/when it does get the land, Salini Impregilo will do the following:

  • supply the civil and infrastructure scope, including the design and construction of the viaduct and embankment sections along the entire route
  • install the track system
  • oversee alignment and construction of all buildings and services that will house maintenance and other rail system equipment

Salini-Lane had previously provided front-end engineering and design for the train's civil infrastructure, as well as an analysis of construction costs and schedule estimates.

"Salini-Lane's unmatched track record with rail infrastructure and, very specifically, its world-class high-speed rail expertise across the globe will be central to the completion of America's first end-to-end high-speed rail system," Aguilar says.

Salini's CEO Pietro Salini says in a statement that the company is both thrilled and honored to bring its large-scale railway expertise to the project.

Salini Impregilo is active in more than 50 countries on five continents, with experience building more than 4,000 miles of railway infrastructure around the world. It has built high-speed train projects in Europe and some iconic projects in the world, including the expansion of the Panama Canal.

Although the company has worked in the U.S. since the 1980s, it expanded its presence in 2016 when it merged with The Lane Construction Corporation, a U.S.-based company with almost 130 years of experience in infrastructure work.

The Texas train will be based on Central Japan Railway's Tokaido Shinkansen train system, which is considered the safest mass transportation system in the world.

The system has transported more than 10 billion passengers in 54-plus years, with no fatalities or injuries from operations, and has an impeccable on-time performance record.

It will debut a new train, the Shinkansen N700S, the sixth generation of this train, before the 2020 Olympics.

Rice University lands $18M to revolutionize lymphatic disease detection

fresh funding

An arm of the U.S. Department of Health and Human Services has awarded $18 million to scientists at Rice University for research that has the potential to revolutionize how lymphatic diseases are detected and help increase survivability.

The lymphatic system is the network of vessels all over the body that help eliminate waste, absorb fat and maintain fluid balance. Diseases in this system are often difficult to detect early due to the small size of the vessels and the invasiveness of biopsy testing. Though survival rates of lymph disease have skyrocketed in the United States over the last five years, it still claims around 200,000 people in the country annually.

Early detection of complex lymphatic anomalies (CLAs) and lymphedema is essential in increasing successful treatment rates. That’s where Rice University’s SynthX Center, directed by Han Xiao and Lei Li, an assistant professor of electrical and computer engineering, comes in.

Aided by researchers from Texas Children’s Hospital, Baylor College of Medicine, the University of Texas at Dallas and the University of Texas Southwestern Medical Center, the center is pioneering two technologies: the Visual Imaging System for Tracing and Analyzing Lymphatics with Photoacoustics (VISTA-LYMPH) and Digital Plasmonic Nanobubble Detection for Protein (DIAMOND-P).

Simply put, VISTA-LYMPH uses photoacoustic tomography (PAT), a combination of light and sound, to more accurately map the tiny vessels of the lymphatic system. The process is more effective than diagnostic tools that use only light or sound, independent of one another. The research award is through the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics and pHenotyping Technologies (LIGHT) program, part of the U.S. HHS, which saw the potential of VISTA-LYMPH in animal tests that produced finely detailed diagnostic maps.

“Thanks to ARPA-H’s award, we will build the most advanced PAT system to image the body’s lymphatic network with unprecedented resolution and speed, enabling earlier and more accurate diagnosis,” Li said in a news release.

Meanwhile, DIAMOND-P could replace the older, less exact immunoassay. It uses laser-heated vapors of plasmonic nanoparticles to detect viruses without having to separate or amplify, and at room temperature, greatly simplifying the process. This is an important part of greater diagnosis because even with VISTA-LYMPH’s greater imaging accuracy, many lymphatic diseases still do not appear. Detecting biological markers is still necessary.

According to Rice, the efforts will help address lymphatic disorders, including Gorham-Stout disease, kaposiform lymphangiomatosis and generalized lymphatic anomaly. They also could help manage conditions associated with lymphatic dysfunction, including cancer metastasis, cardiovascular disease and neurodegeneration.

“By validating VISTA-LYMPH and DIAMOND-P in both preclinical and clinical settings, the team aims to establish a comprehensive diagnostic pipeline for lymphatic diseases and potentially beyond,” Xiao added in the release.

The ARPA-H award funds the project for up to five years.

Houston doctor wins NIH grant to test virtual reality for ICU delirium

Virtual healing

Think of it like a reverse version of The Matrix. A person wakes up in a hospital bed and gets plugged into a virtual reality game world in order to heal.

While it may sound far-fetched, Dr. Hina Faisal, a Houston Methodist critical care specialist in the Department of Surgery, was recently awarded a $242,000 grant from the National Institute of Health to test the effects of VR games on patients coming out of major surgery in the intensive care unit (ICU).

The five-year study will focus on older patients using mental stimulation techniques to reduce incidences of delirium. The award comes courtesy of the National Institute on Aging K76 Paul B. Beeson Emerging Leaders Career Development Award in Aging.

“As the population of older adults continues to grow, the need for effective, scalable interventions to prevent postoperative complications like delirium is more important than ever,” Faisal said in a news release.

ICU delirium is a serious condition that can lead to major complications and even death. Roughly 87 percent of patients who undergo major surgery involving intubation will experience some form of delirium coming out of anesthesia. Causes can range from infection to drug reactions. While many cases are mild, prolonged ICU delirium may prevent a patient from following medical advice or even cause them to hurt themselves.

Using VR games to treat delirium is a rapidly emerging and exciting branch of medicine. Studies show that VR games can help promote mental activity, memory and cognitive function. However, the full benefits are currently unknown as studies have been hampered by small patient populations.

Faisal believes that half of all ICU delirium cases are preventable through VR treatment. Currently, a general lack of knowledge and resources has been holding back the advancement of the treatment.

Hopefully, the work of Faisal in one of the busiest medical cities in the world can alleviate that problem as she spends the next half-decade plugging patients into games to aid in their healing.
