Science Finds a Super Easy Way to Lose Weight

Even if you order seemingly healthy dishes, your restaurant habit is likely derailing your weight loss efforts.

It’s been a long day, you’re tired, and the last thing you want to do is trudge to the grocery store and slave over the stove to make dinner. But hold up; don’t tell your hubby to meet you at your favorite restaurant just yet—especially if you’re trying to shed weight. According to a new study in the Journal of the Academy of Nutrition and Dietetics, nearly all restaurant entrées carry more calories than you should eat in a single meal. Even worse, a fair number of restaurants manage to load their meals with an entire day's worth of calories!

To come to this stomach-churning discovery, researchers from Tufts University visited both independent and chain restaurants across the country and purchased dozens of popular entrees from gyros and spaghetti to meatballs to burritos.

How to Perform CPR

Forget mouth-to-mouth rescue breaths. This expert-backed technique is the correct way to perform this lifesaver

Sudden cardiac arrest occurs when the heart unexpectedly stops beating, which cuts off blood flow to the brain and other organs. If not treated, it can cause death within minutes.

In fact, only about 10 percent of people overall who experience it outside a hospital survive with their brain functions intact, a new study in JAMA found.

But early action can stave off the Grim Reaper: When sudden cardiac arrest victims first received CPR from bystanders, they were more likely to survive with favorable prognoses, the researchers discovered.

But the way you perform CPR has changed in recent years. You no longer have to put your mouth on the victim’s.

Sleep Apnea Triggers Pediatric Fatty Liver Disease Progression

Obstructive sleep apnea and low nighttime oxygen - which results in oxidative stress - may trigger progression of pediatric non-alcoholic fatty liver disease to non-alcoholic steatohepatitis.

Non-alcoholic fatty liver disease (NAFLD) describes the accumulation of fat in the liver of people who drink little or no alcohol. In some individuals with the condition, the accumulated fat causes inflammation and scarring in the liver, resulting in a more serious form of the disease called non-alcoholic steatohepatitis (NASH).

A disease of epidemic proportions, rates of NAFLD are increasing worldwide in both adults and children. NAFLD affects an estimated 30 percent of the population in Western countries and up to 9.6 percent of all children.

Around 38 percent of obese children are affected across the NAFLD spectrum, which includes isolated hepatic steatosis, non-alcoholic steatohepatitis, and cirrhosis.

A combination of OSA and low nighttime oxygen triggered NAFLD progression in obese adolescents.

Appendicitis: Warning Signs and Early Symptoms

Appendicitis is a condition in which the appendix becomes inflamed. Its symptoms can become very uncomfortable, painful, and potentially life-threatening if left untreated.

Sudden appendicitis is the most common cause of acute abdominal pain requiring surgery in the United States. Additionally, more than 5 percent of the population develops appendicitis at some point.

Though it most commonly occurs between the ages of 10 and 30, appendicitis can develop at any age.

The appendix is a tube-shaped piece of tissue attached to part of the long intestine and severe pain is
often the first symptom of appendicitis. In most cases, it will begin near the belly button and surgery
may be needed to treat a case of appendicitis.

Resolving QC Failures

Most medical technologists and technicians, responsible for outputting test results as quickly and reliably as possible, hate it when their smooth flow of work is abruptly interrupted by an out-of-control QC rule flag. Suddenly they are faced with delayed reports, the prospect of a complicated technical investigation, and a litany of questions they must ask themselves, such as:

“Is the out-of-control condition real?”
“Do I really have a problem with the analytical system?”
“If I do have a problem, when did it start and how many patient samples are affected?”
“What should I do first?”
“What should I do next?”

The laboratory would have much less of a conundrum if it were using a new QC rule proposed in a 2012 Clinical Chemistry article.1 This rule allows, as part of its process control, the possibility of a second set of QC measurements when the first results are inconclusive.

Clinical Case Study: Red Brown Urine in a Patient with Chronic HIV Infection and Quadriparesis

A 42-year-old woman with chronic HIV infection presented with sudden onset of progressive limb weakness, leading to immobility within 4 days. This was preceded by severe abdominal pain, nausea, and vomiting for 2 days and episodes of confusion and agitation.

Six weeks prior, she had commenced highly active antiretroviral therapy (HAART), consisting of efavirenz/emtricitabine/tenofovir and cotrimoxazole for opportunistic infection prophylaxis. Additional history included constipation for 4 weeks and an admission for psychiatric symptoms 1 week before starting HAART. She had declined HAART when HIV infection was diagnosed 6 years earlier, but was successfully treated for multidrug-resistant tuberculosis.

Pre-Dementia Memory Loss Improved With Acupuncture

Acupuncture appears to be effective for the mild cognitive impairment that is a precursor for dementia, when used as an alternative or in combination with other treatment, a new study finds.

The review of available published evidence and presented in Acupuncture in Medicine shows promise for clinical effectiveness and safety of acupuncture use for the pre-dementia state. However, the authors caution that further, more rigorously designed studies are needed.

Min Deng, from the Department of Neurology at Zhongnan Hospital of Wuhan University in China, and Xu-Feng Wang, from the Department of General Surgery at Renmin Hospital of Wuhan University, conducted the study.

Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and the most severe decline of dementia.

Acupuncture may assist with improving the subtle memory loss that precedes the development of
dementia.

External and Internal QC for Blood Gases

Quality Control (QC) and Quality Assurance (QA) in the clinical lab have changed. The Centers for Medicare and Medicaid Services (CMS) has embraced a voluntary QC option for meeting CLIA quality control standards called Individualized Quality Control Plan (IQCP), which was implemented in January 2016 for all labs that have been utilizing Equivalent Quality Control (EQC). CLIA QC regulations will remain the same as published in 2003. All of the pre-analytical, analytical, and post-analytical systems requirements in the CLIA regulations will remain in effect.

There are many different aspects of the IQCP for laboratories to consider. This article will cover the minimum requirements for use of external quality controls with regard to blood gas QC.

Minimum guidelines

The minimum guidelines according to CLIA 88 (2003) require laboratories to perform external quality control at least one time per eight-hour shift.1 The IQCP does not change this requirement. In addition to the daily QC requirement, the laboratory is also responsible for calibration verification for all non-waived “moderate to high-complexity” test systems.

Throat Cancer: Get the Facts

The throat is often described as having many different parts. This article looks at two of the more common places throat cancer can occur: the pharynx and the larynx.

The pharynx is most commonly thought of as the throat. It is a tube around 5 inches long that leads from behind the nose to the food pipe.
The larynx is also known as the voicebox. It is a short passage just below the pharynx. The larynx holds the vocal cords and a small piece of tissue called the epiglottis.

The epiglottis moves to cover the top of the larynx so food cannot enter it when people breathe.
