Use of cryopreserved oocytes in patients with poor ovarian response

JAMA Network Open

(Press-News.org)

About The Study: This study of 67,000 freezing cycles among 47,000 patients reveals a distinct pattern in the utilization of cryopreserved oocytes among patients undergoing planned oocyte cryopreservation in the U.S. Despite the increase in number of patients pursuing oocyte cryopreservation, there is a notably low rate of return to utilize previously vitrified oocytes; notably, patients with poor ovarian response are more likely to return, although the time to return is similar to those with normal ovarian response. 

Authors: Yuval Fouks, M.D., M.P.H., of Boston IVF-The Eugin Group in Waltham, Massachusetts, is the corresponding author.

Problem-solving skills training for parents of children with chronic health conditions

2024-01-02
About The Study: The findings of this systematic review and meta-analysis of 23 randomized clinical trials including 3,100 parents suggest that problem-solving skills training for parents of children with chronic health conditions may improve the psychosocial well-being of the parents, their children, and their families. Further high-quality randomized clinical trials with longer follow-up times and that explore physical and clinical outcomes are encouraged to generate adequate evidence.  Authors: Yuanhui Luo, Ph.D., of Central South University in Changsha, Hunan, China, is the corresponding ...

Reducing inequality is essential in tackling climate crisis, researchers argue

2024-01-02
In a report just published in the journal Nature Climate Change, researchers argue that tackling inequality is vital in moving the world towards Net-Zero – because inequality constrains who can feasibly adopt low-carbon behaviours. They say that changes are needed across society if we are to mitigate climate change effectively. Although wealthy people have very large carbon footprints, they often have the means to reduce their carbon footprint more easily than those on lower incomes. The researchers say there is ...

First step towards synthetic CO2 fixation in living cells

First step towards synthetic CO2 fixation in living cells
2024-01-02
Synthetic biology offers the opportunity to build biochemical pathways for the capture and conversion of carbon dioxide (CO2). Researchers at the Max-Planck-Institute for Terrestrial Microbiology have developed a synthetic biochemical cycle that directly converts CO2 into the central building block Acetyl-CoA. The researchers were able to implement each of the three cycle modules in the bacterium E.coli, which represents a major step towards realizing synthetic CO2 fixing pathways within the context of living cells. Developing new ways for the capture and conversion of CO2 is key to tackle ...

Continuous glucose monitoring

2024-01-02
Monitoring glucose levels is one of the key elements in health monitoring. A research team has now developed a battery-independent fluorescent nanosensor based on single-wall carbon nanotubes and an inactive form of the enzyme glucose oxidase (GOx). Because the enzyme is not in its active form, the analyte is not consumed during the measurement, and continuous, reversible, and non-invasive bioimaging of glucose levels in body fluids and tissues is possible, the team reports in the journal Angewandte Chemie. Blood glucose levels are typically measured using GOx-based electrochemical sensors. However, these sensors ...

Researchers receive USDA grant to study changing food spending patterns

Researchers receive USDA grant to study changing food spending patterns
2024-01-02
After a long day, there’s the age-old question of do we eat out or stay in? Over the last decade, that answer has increasingly shifted to eating out. In that timeframe, households have increasingly spent more money on food outside of the home than what's spent on eating at home. In that same time, the farmer’s share of the food dollar eaten outside of the home has declined while the share of food eaten at home has increased. With a more than $550,000 grant from the National Institute of Food and Agriculture, researchers George Davis and Anubhab Gupta, in the Department of Agricultural and Applied Economics in Virginia Tech's College ...

High adolescent BMI increases risk of early chronic kidney disease, according to JAMA study by Hebrew University researchers

2024-01-02
New study finds that adolescent obesity significantly heightens the risk of developing early chronic kidney disease in young adulthood. Even those with high-normal BMI are at risk. Severe obesity poses the highest risk, but even mild obesity and being overweight contribute significantly to this increased risk for both males and females. Lowering obesity rates in adolescents is crucial to better managing the risk of kidney disease and subsequent cardiovascular issues. This study emphasizes the need for preventive measures and management of risk factors associated with chronic kidney disease ...

Healthy omega-3 fats may slow deadly pulmonary fibrosis, research suggests

Healthy omega-3 fats may slow deadly pulmonary fibrosis, research suggests
2024-01-02
Could healthy fats found in nuts and fish slow the progression of potentially deadly lung scarring known as pulmonary fibrosis and delay the need for lung transplants?  UVA pulmonary researchers looked at the association between blood-plasma levels of omega-3 fatty acids – the heart-healthy fats found in foods such as salmon and flaxseeds – and the progression of pulmonary fibrosis, as well as how long patients could go without needing a transplant. The researchers found that higher levels of omega-3 were associated with better lung function and longer transplant-free survival. While more research ...

Predicting COVID-19 variant waves with AI

Predicting COVID-19 variant waves with AI
2024-01-02
An AI model can predict which SARS-CoV-2 variants are likely to cause new waves of infection. Current models used to predict the dynamics of viral transmission do not predict variant-specific spread. Retsef Levi and colleagues studied what factors could shape the viral spread based on analysis of 9 million SARS-CoV-2 genetic sequences collected by the Global Initiative on Sharing Avian Influenza Data (GISAID) from 30 countries, along with data on vaccination rates, infection rates, and other factors. The patterns that emerged from this analysis ...

Cultivated kelp can now be as good as wild kelp

Cultivated kelp can now be as good as wild kelp
2024-01-02
Norway’s exports products derived from from tangle kelp (Laminoria hyperborea) and knotted kelp (Ascophyllum nodosu) to the tune of more than NOK 1 billion a year. The industry mainly extracts alginate from kelp, which is used in over 600 different products as diverse as paint, soft serve ice cream, sauces, bandages, nappies, acid reflux medicine and material for encapsulating cells and medicine. However, the market is far from saturated. “Alginate is becoming a scarce commodity on the global market. There are great opportunities here if we could cultivate more kelp that yielded alginate of good enough quality,” says Finn Aachmann, a professor at the Norwegian ...

Researchers identify new coding mechanism that transfers information from perception to memory

2024-01-02
Our memories are rich in detail: we can vividly recall the color of our home, the layout of our kitchen, or the front of our favorite café. How the brain encodes this information has long puzzled neuroscientists. In a new Dartmouth-led study, researchers identified a neural coding mechanism that allows the transfer of information back and forth between perceptual regions to memory areas of the brain. The results are published in Nature Neuroscience. Prior to this work, the classic understanding of brain organization was that perceptual regions of the brain represent the world "as it is," with the ...
