X-ray Text of an interventional: shows new imaging system may cut X-ray exposure for liver cancer patients

Johns Hopkins researchers report that their test of an interventional X-ray guidance device approved by the U.S. Food and Drug Administration in 2013 has the potential to reduce the radiation exposure of patients undergoing intra-arterial therapy (IAT) for liver cancer.

3-D mammography improves cancer detection in dense breasts

3-D mammography improves cancer detection in dense breasts

A major new study being presented at the annual meeting of the Radiological Society of North America (RSNA) has found that digital breast tomosynthesis, also known as 3-D mammography, has the potential to significantly increase the cancer detection rate in mammography screening of women with dense breasts.

Breasts are considered dense if they have a lot of fibrous or glandular tissue but not much fatty tissue. Research has shown that dense breasts are more likely to develop cancer, a problem compounded by the fact that cancer in dense breasts can be difficult to detect on mammograms.
Other imaging modalities like ultrasound and MRI are often used to help find cancers that can't be seen on mammograms, but both modalities have higher rates of false-positive findings, which are suspicious findings that turn out not to be cancer. This higher false-positive rate often results in more tests and unnecessary biopsies, making MRI and ultrasound expensive to implement in high-volume screening programs, according to study lead author Per Skaane, M.D., Ph.D., from the Department of Radiology at Oslo University Hospital in Oslo, Norway.

Dr. Skaane and colleagues have been studying tomosynthesis as a promising breast cancer screening option that addresses some of the limitations of mammography by providing 3-D views of the breast.
"Tomosynthesis could be regarded as an improvement of mammography and would be much easier than MRI or ultrasound to implement in organized screening programs," Dr. Skaane said. "So the intention of our study was to see if tomosynthesis really would significantly increase the cancer detection rate in a population-based mammography screening program."

The researchers compared cancer detection using full-field digital mammography (FFDM) versus FFDM plus digital breast tomosynthesis in 25,547 women between the ages of 50 and 69. Breast density was classified based on the American College of Radiology's Breast Imaging-Reporting and Data System (BI-RADS). The BI-RADS breast density scale runs from 1 to 4, with 1 being the least dense and 4 being the most dense.

There were 257 malignancies detected on FFDM and a combination of FFDM and tomosynthesis in the study group, including 105 in the density 2 group and 110 in density 3. Of the 257 cancers, 211, or 82 percent were detected with FFDM plus tomosynthesis, a significant improvement over the 163, or 63 percent, detected with FFDM alone.

FFDM plus tomosynthesis pinpointed 80 percent of the 132 cancer cases in women with dense breasts, compared to only 59 percent for FFDM alone.
"Our findings are extremely promising, showing an overall relative increase in the cancer detection rate of about 30 percent," Dr. Skaane said. "Stratifying the results on invasive cancers only, the relative increase in cancer detection was about 40 percent."

Tomosynthesis not only improved the cancer detection rate in women with dense breasts, it also helped increase detection for women in the "fatty breast" BI-RADS categories. The addition of tomosynthesis to FFDM improved the cancer detection rate from 68 percent to 84 percent in women with BI-RADS density 1 or 2 breasts.
"Our results show that implementation of tomosynthesis might indicate a new era in breast cancer screening," Dr. Skaane said.

Wireless ECG introduces the ViSi Mobile System

The ViSi Mobile System is able to continuously measure and display all vital signs (ECG, Heart/Pulse Rate, SpO_{2 and} Blood Pressure

Sotera Wireless introduces the ViSi Mobile System, a platform for comprehensive vital signs monitoring that is designed to keep clinicians connected to their patients, whether in or out of bed, or while in transport – “monitoring in motion.”
Featuring comfortable body-worn sensors that allow for freedom of movement, the system enables highly accurate, continuous monitoring of all vital signs.

The ViSi Mobile System is able to continuously measure and display all vital signs (ECG, Heart/Pulse Rate, SpO₂, Blood Pressure (cuff-based and now also cuffless on a beat-to-beat basis), Respiration Rate, Skin Temperature) with monitoring accuracy and resolution typically found in ICUs. In addition to the color touchscreen display on the patient-worn device, platforms such as desktop or tablet PCs can be utilized as remote viewing and notification devices. ViSi Mobile is able to wirelessly transmit data, leveraging existing hospital WiFi infrastructure, and is designed to provide information output in electronic form (i.e. EMR connectivity) as well as print-outs. In the future, the ViSi Mobile System will also include Sotera’s patient Posture / Motion as a “new vital sign.”
ViSi Mobile is a comprehensive system, designed to enhance patient safety by allowing early detection of patient deterioration and connecting clinicians with their patients anywhere, any time.

How ViSi Mobile System Became Famous

There are some certain benefited filed of ViSi Mobile System. They are as follows:

1. Benefit For Patient Safety
2. Benefit For Healthcare
3. Benefit for  Clinician
4. Benefit for Hospital 

Benefit For Patient Safety

The ViSi Mobile Monitor allows wearable, continuous monitoring of all core vital signs. Going forward, it will also add patients’ activity and posture/motion as a “new vital sign” that may help avoid “Never Events” like falls and pressure ulcers. The ViSi Mobile System wirelessly connects patients in or out of bed with their mobile clinicians and provides vital signs information

Only 3 in 10 Americans with HIV have virus in check

Only 3 in 10 Americans with HIV Have virus in check

November 26, 2014
Just 30% of the 1.2 million Americans with HIV had the virus under control in 2011, according to a report released yesterday by the Centers for Disease Control and Prevention. Among those who don’t have their virus in check, two-thirds have been diagnosed, but are no longer in care, according to the report. When used consistently, antiretroviral treatment can keep HIV at very low levels in the body (known as viral suppression), allowing people with HIV to live longer, healthier lives and substantially reducing the likelihood that they will transmit the virus to others. The report says doctors, nurses and health care systems should test patients for HIV as a regular part of medical care; counsel patients who do not have HIV on how to prevent it; make sure people living with HIV are prescribed and take HIV medicines, stay in care and get supportive services; and work with health departments to get and keep people in HIV medical care.

SurgiBot, a Robotic Version of Spider Surgical System Video

Trans Enterics (Durham, NC), maker of the highly articulating single-site Spider laparoscopic surgical system, just released a preview video of a robotized version of the device. Manipulation of the two pincers looks pretty intuitive, but the controls for the articulating light are less so. There’s the ability to change the scale the movement of the device so that during close-up work the surgeon can gain a new level of precision with a push of a button.
Though the device is still in development, the company hopes it will be a cheaper alternative to other robotic surgical systems. We’re thinking they’re thinking of the da Vinci. Check out the SurgiBot:
