Study: When hospital workers get vaccines, community flu rates fall

Public health data in California reveals for every 15 hospital vaccinations, there is one fewer case of flu in the community

2014-06-04

(Press-News.org) Anaheim, Calif., June 4, 2014 – For every 15 healthcare providers who receive the influenza vaccination, one fewer person in the community will contract an influenza-like illness, according to a study using California public health data from 2009 – 2012.

In an abstract that will be presented on June 7 at the 41st Annual Conference of the Association for Professionals in Infection Control and Epidemiology (APIC), a researcher analyzed archival data from the California Department of Public Health to determine the relationship between vaccinating healthcare personnel against influenza and the rate of influenza-like illness in the surrounding community.

"This study suggests that there is a strong connection between how many healthcare personnel are vaccinated against the flu and how many cases of influenza-like illnesses are reported in the community," said James F. Marx, PhD, RN, CIC, investigator and founder of Broad Street Solutions, an infection prevention consultancy. "More research would be helpful to further understand the impact of vaccinating healthcare workers on community influenza rates."

For the 2011-2012 influenza season, the influenza vaccination rate of California hospital healthcare personnel was 68 percent. According to Marx, if 90 percent of California healthcare personnel were vaccinated – the goal set by the federal government's Healthy People 2020 initiative – there would be about 30,000 fewer cases of influenza-like illness in California.

Influenza-like illness causes more than 200,000 hospitalizations each year and, on average, 24,000 people die as a result, according to the Centers for Disease Control and Prevention (CDC). Currently, vaccination is the single best way to prevent the flu.

Marx said: "It is critical that healthcare providers receive the flu vaccine since they come into contact with our most vulnerable community members."

Beginning last flu season, the County of Los Angeles was one of 12 California counties that began requiring healthcare personnel to receive the influenza vaccination or wear protective masks. APIC recommends that all healthcare personnel – in acute care hospitals, long-term care and other facilities – require annual influenza immunization as a condition of employment unless there are compelling medical contraindications. Read the APIC position paper on influenza vaccination.

"Efforts to promote influenza vaccination of healthcare personnel have traditionally focused on protecting patients inside healthcare facilities," said APIC 2014 President Jennie Mayfield, BSN, MPH, CIC. "Now we have evidence that through enhanced healthcare worker vaccination we can protect the broader community. This represents a tremendous public health opportunity."

MU scientists successfully transplant, grow stem cells in pigs

2014-06-04

COLUMBIA, Mo. – One of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts. This rejection can render experiments useless, making research into potentially life-saving treatments a long and difficult process. Now, researchers at the University of Missouri have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection. "The rejection of transplants and grafts by host bodies is a huge hurdle for medical researchers," ...

Saturated fat intake may influence a person's expression of genetic obesity risk

2014-06-04

Boston, MA (June 4, 2014) ─ Limiting saturated fat could help people whose genetic make-up increases their chance of being obese. In a new study, researchers from the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University identified 63 gene variants related to obesity and used them to calculate a genetic risk score for obesity for more than 2,800 white, American men and women enrolled in two large studies on heart disease prevention. People with a higher genetic risk score, who also consumed more of their calories as saturated fat, ...

Ice cream sensations on the computer

Changes in coldness, creaminess or texture that we experience in the mouth while we are eating an ice cream can be visualised on a screen using coloured curves. Graphs help manufacturers improve product quality, as proven by researchers at the Institute of Agrochemistry and Food Technology in Valencia, Spain. In the last five years a technique known as 'Temporal Dominance of Sensations' (TDS) has become popular, used to analyse how consumer impressions evolve from the moment they taste a product. Researchers at the Institute of Agrochemistry and Food Technology (CSIC) ...

Weight loss surgery also safeguards obese people against cancer

2014-06-04

Weight loss surgery might have more value than simply helping morbidly obese people to shed unhealthy extra pounds. It reduces their risk of cancer to rates almost similar to those of people of normal weight. This is the conclusion of the first comprehensive review article taking into account relevant studies about obesity, cancer rates and a weight loss procedure called bariatric surgery. Published in Springer's journal Obesity Surgery, the review was led by Daniela Casagrande of the Universidade Federal do Rio Grande do Sul in Brazil. With bariatric surgery, a part ...

Observed by Texas telescope: Light from huge explosion 12 billion years ago reaches Earth

2014-06-04

Intense light from the enormous explosion of a star more than 12 billion years ago — shortly after the Big Bang — recently reached Earth and was visible in the sky. Known as a gamma-ray burst, light from the rare, high-energy explosion traveled for 12.1 billion years before it was detected and observed by a telescope owned by Southern Methodist University, Dallas. Gamma-ray bursts are believed to be the catastrophic collapse of a star at the end of its life. SMU physicists report that their telescope was the first on the ground to observe the burst and to capture an ...

A new approach to diversity research

2014-06-04

When people work in socially homogeneous groups, they overestimate their own contributions to the group's success, according to a new study co-authored by an MIT scholar. In fact, in some cases such "self-serving bias" occurs to a degree about five times as great in homogeneous groups as in ethnically diverse groups. Such results raise a larger point, suggests Evan Apfelbaum, the W. Maurice Young Assistant Professor of Organization Studies at the MIT Sloan School of Management, and the lead author of the new study: Researchers have often used homogeneous social groups ...

NASA should maintain long-term focus on Mars as 'horizon goal' for human spaceflight

2014-06-04

WASHINGTON – Arguing for a continuation of the nation's human space exploration program, a new congressionally mandated report from the National Research Council concludes that the expense of human spaceflight and the dangers to the astronauts involved can be justified only by the goal of putting humans on other worlds. The report recommends that the nation pursue a disciplined "pathway" approach that encompasses executing a specific sequence of intermediate accomplishments and destinations leading to the "horizon goal" of putting humans on Mars. The success of this approach ...

Multilingual or not, infants learn words best when it sounds like home

2014-06-04

Los Angeles, London (June 04, 2014). Growing up in a multilingual home has many advantages, but many parents worry that exposure to multiple languages might delay language acquisition. New research could now lay some of these multilingual myths to rest, thanks to a revealing study that shows both monolingual and bilingual infants learn a new word best from someone with a language background that matches their own. While 1.5 year old babies are powerful word learners, they can have difficulty learning similar-sounding words (e.g., "coat" and "goat"). A string of previous ...

Shaken, not stirred: Control over complex systems consisting of many quantum particles

2014-06-04

This news release is available in German. Sometimes quantum particles behave like waves. This phenomenon is often used for high precision measurements, for instance in atomic clocks. Usually, only the wave properties of single particles play a role, but now researchers at the Vienna Center for Quantum Science and Technology, Vienna University of Technology have succeeded in quantum mechanically controlling hundreds of Rubidium atoms of an ultracold Bose-Einstein-condensate by shaking it in just the right way. Now, not only internal states of atoms can be used for ...

Five-question clinical tool the first to help screen risk of violence in military veterans

2014-06-04

CHAPEL HILL, N.C. -- A new brief, 5-question screening tool can help clinicians identify which veterans may be at greater risk of violence, according to a new study led by a UNC researcher. The study, published online by the American Journal of Psychiatry, is based on a national survey sample of veterans combined with a smaller, in-depth assessment sample. The screening tool, called the Violence Screening and Assessment of Needs (VIO-SCAN), asked veterans about financial stability, combat experience, alcohol misuse, history of violence or arrests, and probable posttraumatic ...
