Patients Often Withhold Information From Providers
Patients often do not disclose medically relevant information to their healthcare providers, according to results of a study published online November 30 in JAMA Network Open.

HIV: Global Map Reveals Challenge to Vaccine Development
A study to be published in The Lancet Infectious Diseases on World AIDS Day shows the extraordinary global genetic diversity of HIV and highlights just how big the challenge is to develop a vaccine to combat the global spread of HIV.
AIDS Stigma Remains in Australia, Research
As Australia marks World AIDS Day on Saturday 1 December, new research reveals the enduring challenge of tackling stigma surrounding HIV. The Stigma Indicators Monitoring Project: People Living with HIV, by the UNSW Sydney Center for Social Research in Health (CSRH), is jointly released with The Australian Federation of AIDS Organization (AFAO).
Malaria Diagnosis Improved Using Old Smartphones
Their ambitious attempt to improve the diagnosis of malaria in developing countries has clinched them the runner-up spot in the international James Dyson Award 2018. Over 212 million cases of malaria are reported annually, with the majority of incidences occurring in Sub-Saharan Africa.
However, a lack of medical resources means blood sample analysis is often delayed, leading to errors and ultimately high mortality rates. Seeking to improve the efficiency and accuracy of diagnosis, a group of students from Delft University of Technology are developing Excelscope, a semi-automated malaria diagnostic device.
High Yield Cell-Free Protein Expression Kit Introduced
AMSBIO introduces ALiCE® – a new high yield cell-free protein expression system. Cell-free protein expression (CFPE) is today used by protein chemists to quickly produce small amounts of proteins when screening DNA libraries. However current technologies are limited and there is a need for higher protein expression yields.
Effects of Long-Term Missions on the ISS on Skin Physiological Parameters
Skin reaction to spaceflight has not really been studied yet, although the skin has a very important barrier function to protect the body and can contribute to a more general understanding of physiology. It is proposed here to make a more thorough investigation of the skin during long-term spaceflight, using noninvasive techniques.
Bigger Brains are Smarter, But Not by Much
The English idiom "highbrow," derived from a physical description of a skull barely able to contain the brain inside of it, comes from a long-held belief in the existence of a link between brain size and intelligence. The study is published in the journal Psychological Science.
Studying Flu: A New Approach Highlighted
Scientists have known for decades that a flu virus in a human body can be a lot different than viruses grown in a lab. As opposed to the uniform, spherical, textbook-style viruses in a petri dish, in humans they vary in shape and composition — particularly the abundance of certain proteins — even if they are genetically very similar.
Lung Diseases in Premature Babies: Treatment with Innovative Inhalation System
Premature babies who have born before their lungs have finished maturing often suffer from a lack of surfactant – a necessary substance for lung development. They are also particularly susceptible to illnesses of the respiratory organ, which have to be treated by means of inhalation. However, the inhalation systems available are not geared to the needs of preterm infants and newborns. Researchers are working with partners to develop a system that would allow drugs to be administered as aerosols in an efficient and breath-triggered manner. This would shorten the duration of therapy, so easing the strain on little bodies.
Nanocarrier-Delivered MicroRNA In Sepsis Treatment
One in three patients who die in the U.S. dies of sepsis, according to the Centers for Disease Control and Prevention. It is one of the leading causes of death in intensive care units and, with an estimated price tag of $20 billion in 2011, the most expensive condition that hospitals treat.
New Method Developed to Detect Viral RNA Without Special Equipment
Scientists from the SCAMT Laboratory of ITMO University developed a method to detect viral RNA without special equipment. The sensor is based on a polymerization reaction: if the sample contains traces of the target virus, then under the ultraviolet irradiation the liquid-sensor turns into a gel.
The results of such an analysis can easily be detected even by people with limited vision. As the required reagents are widely available and resistant to temperature extremes, the method can be used in difficult field conditions. The results are published in RSC Advances.
Effectiveness of Oils from Herbs Against Lyme Disease Bacteria
Oils from garlic and several other common herbs and medicinal plants show strong activity against the bacterium that causes Lyme disease, according to a study by Johns Hopkins Bloomberg School of Public Health. These oils may be especially useful in alleviating Lyme symptoms that persist despite standard antibiotic treatment, the study also suggests.
