Scientists Have Developed a Type of HIV Test on a USB Stick
November 10th 2016Scientists have developed a type of HIV test on a USB stick. The device, created by scientists at Imperial College London and DNA Electronics, uses a drop of blood to detect HIV, and then creates an electrical signal that can be read by a computer, laptop or handheld device. The disposable test could be used for HIV patients to monitor their own treatment. Furthermore, the technology could enable patients with HIV to be managed more effectively in remote locations.
Could an Iron-Grabbing Molecule Help Prevent UTIs? New Vaccine Shows Promise in Mice
November 8th 2016For most invading bacteria, the bladder is not a friendly place. But for those that have figured out how to scavenge iron from their hosts, it’s a fine place to grow and reproduce. And for millions of women a year, that means painful, burning, potentially dangerous urinary tract infections. Now, in an ironic twist, scientists have turned that iron-scavenging power against the most common UTI-causing bacteria.
Early Study Finds Antibody That 'Neutralizes' Zika Virus
November 7th 2016Researchers at Vanderbilt University Medical Center and Washington University School of Medicine in St. Louis, Missouri, have isolated a human monoclonal antibody that in a mouse model “markedly reduced” infection by the Zika virus.
Scientists Develop Method for Faster Diagnosis of Sepsis-Causing Pathogens
November 7th 2016It is estimated that in Germany alone around 150,000 people fall ill with sepsis every year; despite medical advances, between 30 percent and 50 percent of the patients still die of the consequences. One of the reasons for the high mortality rate: the diagnosis often comes too late for the lifesaving therapy with antibiotics that only combat the specific causative pathogen. In general the sepsis pathogens are detected by means of so-called blood cultures in which the pathogenic organism from blood samples of the patients are cultivated in the laboratory. Here, two to five days pass before the pathogens have multiplied and a result is available. Due to rapid progress in nucleic acid analysis, the currently available high-throughput technologies (Next-Generation Sequencing) make it possible to sequence the complete genome of organisms within just a few hours and to check them against known gene sequences.
New Method Allows to Detect the Presence in Ham of the Parasite That Causes Toxoplasmosis
November 4th 2016Scientists from the universities of Granada (UGR) and Valencia (UV) have developed a new molecular method for determining the presence of the parasite Toxoplasma gondii, which causes toxoplasmosis, in samples of ham.
Implications of the Growing Antibiotic Resistance in Patient Care
November 3rd 2016The discovery of penicillin and subsequent generations of antibiotics has been heralded as one of the biggest medical discoveries in history. Yet shortly after his discovery of penicillin in 1928, Fleming warned of the dangers of resistance. This fear has since been proven to be accurate. Within a few years of the introduction of each new class of antibiotics, resistance was detected, helping drive the need for development of the next blockbuster antibiotic.
Cleanliness is Contagious: Analyzing the Significance of HCAHPS' Question 8
November 3rd 2016With flu season around the corner and the latest Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) deadline just passed, now seems the ideal time to explore the issue of cleanliness, the topic of Question 8 of that quarterly survey. Almost every aspect of the healthcare environment involves decontamination. After all, a hospital is the last place where germs should flourish and spread. And these days, with the HCAHPS reporting mandate in place, the subject of cleanliness – and the poll’s other questions as well – has become even more important. Patients’ responses to HCAHPS influence a hospital’s reputation and finances. Therefore, as fall and winter bring bouts of flu cases and facilities aim to stay at the top of their survey scores, some pointers on cleanliness principles and procedures may be what the doctor ordered.
