Do different plant-based diets affect pregnancy and birth outcomes?

2024-01-24
(Press-News.org) Women who follow vegan diets during pregnancy may face higher risks of developing preeclampsia and of giving birth to newborns with lower birth weight, suggests a recent study published in Acta Obstetricia et Gynecologica Scandinavica.

For the study, 65,872 women identified themselves as omnivorous, 666 as fish/poultry vegetarians, 183 as lacto/ovo vegetarians, and 18 as vegans. Based on a questionnaire completed mid-pregnancy, investigators found that protein intake was lower among lacto/ovo vegetarians (13.3%) and vegans (10.4%) compared with omnivorous participants (15.4%). Micronutrient intake was also much lower among vegans, but when dietary supplements were considered, no major differences were observed.

Compared with omnivorous mothers, vegan mothers had a higher prevalence of preeclampsia (a pregnancy complication characterized by high blood pressure), and their newborns weighed an average of 240 g less.

“Further research is needed regarding possible causality between plant-based diets and pregnancy and birth outcomes, to strengthen the basis for dietary recommendations,” the authors wrote

Do couples’ wages differ based on interracial versus intraracial marriage?

2024-01-24
In a study published in Economic Inquiry, investigators compared wages of Black and white interracially married individuals with those of intraracially married individuals in the United States. After controlling for other factors that influence wages, the researchers found a wage penalty for white males in interracial marriages and a wage premium for Black males in interracial marriages, compared with their same sex and race counterparts in intraracial marriages. There were no wage penalties or premiums for white or Black females in interracial marriages. The study also ...

How does climate change affect eczema?

2024-01-24
In an analysis of all relevant published studies that assessed atopic dermatitis (also known as eczema) associated with trends in climate-related hazards due to greenhouse gas emissions, investigators found that impacts include direct effects on eczema, like particulate matter-induced inflammation from wildfires, and indirect effects, such as stress resulting from drought-induced food insecurity.    In their research published in Allergy, the scientists created maps showing the past, ...

Can genetics affect the need for surgery in patients with thumb osteoarthritis?

2024-01-24
Rhizarthrosis, also known as trapeziometacarpal osteoarthritis, is a type of osteoarthritis that affects the thumb, and treatments range from splints to surgery. Investigators have uncovered various genetic differences between individuals with rhizarthrosis who undergo surgery for their condition versus those who opt for nonsurgical treatments. The study, which is published in the Journal of Orthopaedic Research, included 1,083 surgical patients and 1,888 nonsurgical patients with rhizarthrosis, as well as 205,371 controls ...

AA attendance lower among African American, Hispanic and young populations

AA attendance lower among African American, Hispanic and young populations
2024-01-24
By Amy Norton Alcoholics Anonymous has long been a cornerstone of treating alcohol use disorders in the United States. But even today, Americans are not accessing it equally, according to a new study in the Journal of Studies on Alcohol and Drugs. Alcoholics Anonymous, or AA, got its start nearly 90 years ago and is famous for spurring the "12-step" approach to recovery -- which includes acknowledging powerlessness over alcohol and giving your life over to a "higher power." Over the years, AA and similar "mutual-help groups" ...

Why do carrots curl? Research reveals the mechanics behind root vegetable ageing

2024-01-24
Chopped carrot pieces are among the most universally enjoyed foods and a snacking staple – a mainstay of school lunchboxes, picnics and party platters year-round. Now researchers from the University of Bath have uncovered the secret science of prepping the popular root veg and quantified the processes that make them curl up if left uneaten for too long. Mechanical Engineering student Nguyen Vo-Bui carried out the research as part of his final-year studies, in the limited circumstances of Covid-19 lockdowns of 2021. Without access to labs, Nguyen aimed to identify the geometrical ...

FDG PET/CT imaging after just one week may predict treatment response in patients with advanced melanoma

2024-01-24
Bottom Line: Imaging the tumors of patients with advanced melanoma receiving pembrolizumab (Keytruda) after only one week—rather than the standard of around three months—identified metabolic changes that corresponded with treatment response and progression-free survival (PFS). Journal in Which the Study was Published: Clinical Cancer Research, a journal of the American Association for Cancer Research (AACR) Author: Michael D. Farwell, MD, an associate professor of radiology at the Hospital of the University of Pennsylvania Background: Cancer immunotherapy has helped ...

Centralized social networks potentially hinder innovation by making decision-making too similar

2024-01-24
Social systems where influence is focused around one or a few individuals may create environments where new ideas are ignored, and innovation is hindered. This is according to a study published today in People and Nature by researchers at the University of Sydney and Stockholm University. It looked at the social networks and fertiliser use of 30 rural, cocoa-producing villages in Sulawesi, to examine how innovative and sustainable farming practices are adopted among communities. It found that when one or two farmers hold a disproportionate level of influence (often due to their roles as "model farmers" in official sustainability programs) ...

Tunnelling of electrons via the neighboring atom

Tunnelling of electrons via the neighboring atom
2024-01-24
Tunnelling is one of most fundamental processes in quantum mechanics, where the wave packet could traverse a classically insurmountable energy barrier with a certain probability. Within the atomic scale, tunnelling effects play an important role in molecular biology, such as accelerating enzyme catalysis, prompting spontaneous mutations in DNA and triggering olfactory signaling cascades. Photoelectron tunnelling is a key process in light-induced chemical reactions, charge and energy transfer and radiation emission. The size of optoelectronic chips ...

Space-based landscape site perception: Teaching principles and methods for the basic course of landscape architecture

Space-based landscape site perception: Teaching principles and methods for the basic course of landscape architecture
2024-01-24
Replacing abstract form-making training with the perception of landscape site has been an important trend in the basic course of landscape architecture. Based on theoretical research and the authors’ teaching practice, this article aims to explore the significance, objects, and methods of site perception training. The authors argue that because landscape design is stemmed from the perception and interpretation of site characteristics, experiencing landscape sites must precede form-making training to become the foundation of design learning. Human-scale spaces that concern elements, structure, processes, and feelings for perception, representation, ...

Suppression of deep-level traps for lead-free perovskite solar cells

Suppression of deep-level traps for lead-free perovskite solar cells
2024-01-24
Tin perovskites have gained tremendous attention in lead-free perovskite solar cells. However, Sn vacancies and undercoordinated Sn ions on the tin perovskite surfaces can create deep-level traps, leading to non-radiative recombination and absorption nucleophilic O2 molecules, impeding further device efficiency and stability.   Researchers led by Prof. Ligang Xu at Nanjing University of Posts & Telecommunications, China, are interested in lead-free perovskite solar cells, where the deep-level traps lead to inferior efficiency and stability. The work first introduced semicarbazide hydrochloride (SEM-HCl) into ...
