Inhaling hypertonic saline decreases hospital admissions in children with bronchiolitis

Inhaling hypertonic saline decreases hospital admissions in children with bronchiolitis
2014-05-26
(Press-News.org) A team of researchers, led by physicians from Children's Hospital Los Angeles, have found that infants with bronchiolitis who were treated with inhaled hypertonic saline in the emergency department (ED) were less likely to require admission to the hospital compared to infants treated with normal saline.

The study, conducted at Children's Hospital Los Angeles and UCSF Benioff Children's Hospital Oakland, will be published in JAMA Pediatrics on May 26.

Bronchiolitis is a respiratory infection common in infants and young children that results in approximately 150,000 hospitalizations each year, with an estimated cost of $500 million.

"Previous studies have shown positive effects of using hypertonic saline, a concentrated salt solution, on infants and young children with bronchiolitis," said lead author, Susan Wu, MD, with The Saban Research Institute of Children's Hospital Los Angeles. "What is unique about this study is that we looked at the effect of administering hypertonic saline in the ED and then considered its effect on hospital admission."

The investigators treated 408 babies and young children; 197 received normal saline and 211 received 3% hypertonic saline. Patients were treated with their assigned intervention up to three times in the ED. Those admitted continued to receive the therapy every eight hours until discharge.

Investigators found that 42.6% of patients treated with normal saline required hospital admission compared with 28.9% of patients treated with hypertonic saline.

"We found that infants and young children with bronchiolitis treated with nebulized hypertonic saline in the ED were less likely to require hospitalization," said Wu, who is also an assistant professor of Clinical Pediatrics at the Keck School of Medicine of the University of Southern California. "It's gratifying to find an inexpensive yet effective therapy that helps patients while also reducing the cost of healthcare."

Hot flashes/night sweats solutions: Estrogen therapy vs. Venlafaxine

2014-05-26
BOSTON, MA – A new research study from Brigham and Women's Hospital (BWH) that compares low-dose oral estrogen and low-dose non-hormonal venlafaxine hydrochloride extended release (XR) to placebo were both found effective in reducing the number of hot flashes and night sweats reported by menopausal women. The study is the first clinical trial to simultaneously evaluate estrogen therapy (ET), known as the "gold standard" treatment for hot flashes and night sweats, and a non-hormonal treatment, venlafaxine, a first-line treatment in women who are unwilling or unable to ...

Conflicting conclusions in 2 bronchiolitis studies; editorial explains why

2014-05-26
Less Improvement in Infants with Bronchiolitis After Nebulized Hypertonic Saline Treatment Bottom Line: Children with bronchiolitis (a common respiratory tract infection that can result in hospitalization) who were treated in the emergency department showed less clinical improvement after receiving nebulized 3 percent hypertonic saline (HS) than infants who received normal saline (NS). Author: Todd A. Florin, M.D., M.S.C.E., of the Cincinnati Children's Hospital, and colleagues. Background: Nebulized HS has been shown to increase mucociliary clearance (the clearing ...

Ebola vaccine success highlights dilemma of testing on captive chimps to save wild apes

2014-05-26
The first conservation-specific vaccine trial on captive chimpanzees has proved a vaccine against Ebola virus is both safe and capable of producing a robust immune response in chimpanzees. This unprecedented study, published in the journal PNAS, shows that 'orphan' vaccines - which never complete the expensive licensing process for human use - can be co-opted for use on wildlife and might be a godsend for highly endangered species such as gorillas and chimpanzees, say researchers. They suggest that, by ending captive research in an effort to pay back an "ethical ...

From chaos to order: How ants optimize food search

2014-05-26
Ants are capable of complex problem-solving strategies that could be widely applied as optimization techniques. An individual ant searching for food walks in random ways, biologists found. Yet the collective foraging behaviour of ants goes well beyond that, as a mathematical study to be published in the Proceedings of the National Academy of Sciences reveals: The animal movements at a certain point change from chaos to order. This happens in a surprisingly efficient self-organized way. Understanding the ants could help analyze similar phenomena - for instance how humans ...

Relaxation helps pack DNA into a virus

Relaxation helps pack DNA into a virus
2014-05-26
Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published in in the early edition of the Proceedings of the National Academy of Sciences the week of May 26 and the May 30 issue of Physical Review Letters. DNA is a long, unwieldy molecule that tends to repel itself because it is negatively charged, yet it can spool tightly. Within the heads of viruses, DNA can be packed to near crystalline densities, crammed in by a molecular ...

Breakthrough shows how DNA is 'edited' to correct genetic diseases

2014-05-26
An international team of scientists has made a major step forward in our understanding of how enzymes 'edit' genes, paving the way for correcting genetic diseases in patients. Researchers at the Universities of Bristol, Münster and the Lithuanian Institute of Biotechnology have observed the process by which a class of enzymes called CRISPR – pronounced 'crisper' – bind and alter the structure of DNA. The results, published in the Proceedings of the National Academy of Sciences (PNAS) today, provide a vital piece of the puzzle if these genome editing tools are ultimately ...

Sex-specific changes in cerebral blood flow begin at puberty, Penn study finds

Sex-specific changes in cerebral blood flow begin at puberty, Penn study finds
2014-05-26
PHILADELPHIA – Puberty is the defining process of adolescent development, beginning a cascade of changes throughout the body, including the brain. Penn Medicine researchers have discovered that cerebral blood flow (CBF) levels decreased similarly in males and females before puberty, but saw them diverge sharply in puberty, with levels increasing in females while decreasing further in males, which could give hints as to developing differences in behavior in men and women and sex-specific pre-dispositions to certain psychiatric disorders. Their findings are available in Proceedings ...

A mechanism of how biodiversity arises

A mechanism of how biodiversity arises
2014-05-26
AMHERST, Mass. – A new study of how biodiversity arises, by evolutionary biologists at the University of Massachusetts Amherst, shows how a mutation in a single gene during development can lead to different consequences not only in how animals' skull and jaw are shaped, but how this leads to different feeding strategies to exploit different ecological niches. The study in the cichlid fish model by Yinan Hu, a doctoral student in organismic and evolutionary biology, with his advisor Craig Albertson, is among the first to address how a single genetic change can influence ...

Implications of mandatory flu vaccinations for health-care workers

2014-05-26
Employers planning to implement mandatory influenza vaccination policies for health care workers need to understand the implications, according to an analysis published in CMAJ (Canadian Medical Association Journal). Vaccination rates among health care workers are less than 50%, well below the level necessary for herd immunity. Evidence indicates that vaccination of health care workers can benefit patient health, leading to a move by many to consider mandatory influenza vaccination as a condition of employment or to require employees to wear a mask during influenza season. ...

Neurons can use local stores for communication needs

Neurons can use local stores for communication needs
2014-05-26
Researchers reveal that neurons can utilize a supremely localized internal store of calcium to initiate the secretion of neuropeptides, one class of signaling molecules through which neurons communicate with each other and with other cells. The study appears in The Journal of General Physiology. Neuropeptides are released from neurons through a process that—like other secretory events—is triggered primarily by the influx of calcium into the neuron through voltage-gated channels. Although neuropeptides are stored in large dense core vesicles (LDCVs) that also contain ...
