(Press-News.org) Today, deliveries via cesarean sections, or c-sections, have become quite common globally. Sometimes, c-sections are a medical necessity when normal deliveries become risky either for the mother or the baby. At other times, it can be a choice. C-sections today have become a considerably safer procedure than it was a few decades ago, but there is need to refine it further.

New study determines cystic fibrosis therapy is safe and effective for young children
2021-05-07
Children ages two to five who have the most common form of cystic fibrosis (CF), caused by two copies of the F508 gene mutation, have not had any modulator treatments available to them until recently. A new study authored by researchers at Children's Hospital Colorado and published May 6, 2021, in Lancet Respiratory Medicine shows that the CFTR modulator - lumacaftor/ivacaftor - can be safe and well-tolerated for this age range for up to 120 weeks, allowing younger children to begin proactive treatment of CF earlier in their lives.
CF affects more than 70,000 people worldwide and is a chronic, progressive, life-shortening genetic disease caused by an absent or defective protein called the CF transmembrane conductance regulator (CFTR) protein, resulting from mutations in both copies ...
Emissions from human activity modify biogenic secondary organic aerosol formation
2021-05-07
Despite their extremely small size, submicron atmospheric aerosols are critical pollutants with climate change, air quality, and human health implications. Of these particles, secondary organic aerosols (SOA) form when volatile organic compounds (VOCs) oxidize to lower volatility products that bond with and increase aerosol particle size, or in some cases, they may simply exist by themselves. SOA constitutes a significant fraction of the global aerosol mass. Scientists are attempting to improve future aerosol modeling, but several discrepancies still exist between model-simulated and field-observed SOA budgets.
''Large uncertainties in model assessments of SOA budgets and correspondingly, its climate effects, ...
Discovery of huge Raman scattering at atomic point contact
2021-05-07
Nanofabrication of electronic devices has reached a single nanometer scale (10-9 m). The rapid advancement of nanoscience and nanotechnology now requires atomic-scale optical spectroscopy in order to characterize atomistic structures that will affect the properties and functions of the electronic devices.
The international team headed by Takashi Kumagai at Institute for Molecular Science discovered a huge enhancement of Raman scattering mediated by a formation of an atomic point contact between a plasmonic silver tip and a Si(111)-7×7 reconstructed surface. This was achieved by means of state-of-the-art low-temperature tip-enhanced ...
Algorithms show accuracy in gauging unconsciousness under general anesthesia
2021-05-07
Anesthestic drugs act on the brain but most anesthesiologists rely on heart rate, respiratory rate, and movement to infer whether surgery patients remain unconscious to the desired degree. In a new study, a research team based at MIT and Massachusetts General Hospital shows that a straightforward artificial intelligence approach, attuned to the kind of anesthetic being used, can yield algorithms that assess unconsciousness in patients based on brain activity with high accuracy and reliability.
"One of the things that is foremost in the minds of anesthesiologists is 'Do I have somebody who is lying in front of me who may be conscious and I don't realize it?' Being ...
Learning on the fly
2021-05-07
Even the humble fruit fly craves a dose of the happy hormone, according to a new study from the University of Sussex which shows how they may use dopamine to learn in a similar manner to humans.
Informatics experts at the University of Sussex have developed a new computational model that demonstrates a long sought after link between insect and mammalian learning, as detailed in a new paper published today in Nature Communications.
Incorporating anatomical and functional data from recent experiments, Dr James Bennett and colleagues modelled how the anatomy and physiology of the fruit fly's brain can support learning according to the reward prediction error (RPE) hypothesis.
The computational model indicates how dopamine neurons in an area of ...
Rare genetic disease caused by mutations in protein that controls RNA metabolism
2021-05-07
PITTSBURGH, May 7, 2021 - In a paper published today in Nature Communications, an international group of collaborators led by researchers at UPMC Children's Hospital of Pittsburgh have identified a genetic cause of a rare neurological disorder marked by developmental delay and loss of coordination, or ataxia.
The disorder, scientists found, is caused by mutations in a protein called GEMIN5--one of the key building blocks of a protein complex that controls RNA metabolism in neurons. No mutations in GEMIN5 were previously linked to any genetic disease. ...
Alzheimer Europe calls for people with dementia and carers to be prioritized for vaccine
2021-05-07
Luxembourg, 7 May 2021 - In a new position statement, Alzheimer Europe has issued a call for prioritisation of people with dementia and their carers in national COVID-19 vaccination strategies, urging governments to recognise the disproportionate effect of the pandemic on these groups.
Alzheimer Europe has today issued a call for people with dementia and their carers to be given priority in the ongoing COVID-19 vaccination campaigns across Europe.
In its position statement, Alzheimer Europe notes that people with dementia have almost twice the risk for developing COVID-19 compared to their ...
Systemic inequalities driving exposure to high indoor air pollution in London
2021-05-07
Systemic inequalities mean that low-income households in London are more likely to be exposed to higher levels of indoor air pollution, according to a report by UCL researchers.
The biggest factors are the quality of housing and the characteristics of the surrounding environment, taking location and levels of outdoor air pollution into account - factors beyond occupants' control.
Air pollution exposure is the greatest environmental health threat in the UK, with long-term exposures estimated to cause 28,000-36,000 premature deaths a year.
In the paper, published in Buildings and Cities, researchers used available data and models, assembling evidence to examine five factors explaining why lower socio-economic groups may be exposed to higher levels of indoor air pollution ...
The role of the gut microbiota in inflammatory skin diseases
2021-05-07
LUGANO, 7 May, 2021- Findings presented at today's EADV 2021 Spring Symposium suggest that an imbalance in gut microbiota (dysbiosis), could play a significant role in the progression of inflammatory skin disease, Hidradenitis Suppurativa (HS). HS is a painful, long-term skin condition, with a chronic and relapsing nature that significantly impacts patients' quality of life.
Researchers at Hacettepe University collected faecal samples from 15 patients with HS and 15 age and sex matched healthy individuals and analysed regions of the bacterial 16S rRNA gene to investigate ...
Hand dermatitis in two thirds of public due to stringent hand hygiene during COVID
2021-05-07
LUGANO, 6 May, 2021- The dermatological impact of COVID-19 is a burning topic at EADV's 2021 Spring Symposium. New research presented today highlights the effect that stringent hand hygiene during the pandemic has had on hand skin health.1
Researchers at Father Muller Medical College, India, analysed transepidermal water loss (TEWL - an essential parameter for measuring skin barrier function) from 582 people (291 healthcare professionals (HCPs) and 291 healthy individuals from the general population). Results indicated that hand dermatitis was now present among 92.6% of HCPs and 68.7% of the general population, despite only ~3% of HCPs and 2.4% of the general public in the study having reported a prior history of hand dermatitis (obtained through medical history ...
