How stress increases seizures for patients with epilepsy

It is well known that stress can increase the frequency and severity of seizures for patients with epilepsy. Now, researchers have shed light on why this is, and they may have even found a way to stop it.

Published in the journal Science Signaling, the researchers reveal how epilepsy alters the way brain reacts to stress to cause seizures.

Epilepsy is a neurological disorder characterized by recurrent seizures, which are sudden surges of electrical activity in the brain.

All You Need to Know About Insulin Sensitivity Factor

Insulin is a hormone that plays and important role in the body's metabolism by controlling blood sugar levels and other processes.

It is produced by beta cells in the pancreas and released it into the bloodstream after we eat to enable some body cells, such as muscle, fat, and heart cells, to absorb the sugar from the food we eat.

Insulin also helps store glucose in the liver as glycogen when it is not needed, so it can be released it when blood sugar levels are low or when more energy is needed.

Insulin sensitivity factor reflects how blood sugar levels fall after taking 1 unit of insulin.

Clinical Chemistry and Integrated Test Systems

Lab consolidation drives technological advances and platform integration

Under the emerging integrated health model, the clinical lab is but one strand in a complex web of healthcare partners. From the emergency department (ED), to physician’s offices, to the specialty clinic, patients are often treated at multiple points of care. Achieving reliable test results across the spectrum of healthcare settings, therefore, is not just desirable, but crucial.

Nevertheless, as testing demand surges, laboratory administrators also face budgetary pressures and staffing shortages. This article examines why and how labs are turning to automated technology to accommodate increases in testing volume. Specifically, advances in clinical chemistry analyzers have enabled labs not just to meet ever-growing workloads, but even to improve turnaround times while achieving consistency in results and minimizing labor requirements.

Lab Automation: Renewed Vigor Under Pressure

Over the years, automation in clinical labs has made sizable gains toward improving efficiency and productivity, and delivering timely and accurate results to improve patient outcomes. But automating the many processes used in microbiology departments has been laboratories’ “last frontier,” according to Brad Banks, worldwide marketing manager for lab automation at BD Diagnostics–Diagnostic Systems, Sparks, Md.

Because of the nation’s aging population, the volume of assays performed by US labs is continuing to increase. Yet, at the same time, the number of available techs is decreasing, says Nilam Patel, senior product manager for automation solutions at Sysmex America Inc, Lincolnshire, Ill. Coupled with an increased emphasis on quality and patient outcome initiatives, these trends are leading clinical laboratories to seek automation that provides quality clinical information, maximizes operational efficiency, and minimizes “sample touch points.”

Data Analytics in the Clinical Laboratory

Managing test utilization reveals opportunities for improved laboratory performance and better patient care

The laboratory reimbursement market is shifting away from consumption-, fee-for-service-, and transaction-based paradigms to models based on the quality and value of the services provided by clinical labs. Payors are increasingly asking health systems and their providers to respond by providing high-quality care while being mindful of financial performance.

In turn, the move away from fee-for-service payments in favor of other models of reimbursement—especially bundled payment models—is causing lab managers to take a hard look at how they can reduce unnecessary testing.

Proper QC of Hematology Critical Values

The reporting of critical values—laboratory results that indicate a possible life-threatening situation for a patient—requires rapid clinical intervention in order to avert significant patient morbidity and mortality. Given the imperative of clear, accurate, and expeditious communication of critical value results from the laboratory to clinicians, one method of ensuring prompt handling is to create a protocol that optimizes workflow by eliminating waste and placing checks and balances throughout the process.

As with most vital aspects of laboratory work, managing hematology critical values depends largely on the acumen and aptitude of staff. Thus, an instituted protocol will only be successful if staff technologists are properly trained, gain sufficient knowledge of all involved systems and automation, and are equipped with tools to recognize the effectiveness of checks and balances.

Measles: Causes, Symptoms and Treatments

Measles, also known as Rubeola or morbilli, is a highly infectious illness caused by a virus - a viral infection caused by the rubeola virus.

Measles is an endemic disease; meaning it is continually present in a community and many people develop resistance. If measles enters an area where the people have never been exposed the result can be devastating.

A measles outbreak in 1592 in the island of Cuba killed approximately two-thirds of the native population who had previously survived smallpox. A couple of years later half the indigenous population of Honduras died.

How Much Salt is Too Much?

Salt intake has become a major health concern in the United States. An array of studies have claimed too much salt in the diet can increase the risk of serious illness, such as heart disease and stroke, prompting recommendations to lower salt intake. But how much is "too much" when it comes to salt consumption?

The Dietary Guidelines for Americans recommend that adults consume less than 2,300 milligrams of sodium each day - the equivalent to around 1 teaspoon of salt - as part of a healthy diet.

A report from the Centers for Disease Control and Prevention (CDC) released earlier this year, however, found that around 90 percent of adults and children in the U.S. consume more than the recommended sodium intake, with most adults consuming more than 3,400 milligrams daily.

Current guidelines recommend limiting salt intake to less than 2,300 milligrams daily.

How a single blood test could identify your entire viral infection history

Researchers have created what they say is a "one-stop shop" for diagnosing infections - a test that can determine an individual's complete viral history just by scanning a single drop of blood.

The test, called VirScan, was created by Stephen Elledge and colleagues from the Howard Hughes Medical Institute (HHMI).

"We've developed a screening methodology to basically look back in time in people's [blood] sera and see what viruses they have experienced," explains Elledge. "Instead of testing for one individual virus at a time, which is labor intensive, we can assay all of these at once. It's one-stop shopping."
