First trial of faecal microbiota transplantation for people with active peripheral psoriatic arthritis shows no advantage

A double-blind trial found that faecal microbiota transplantation did not improve treatment outcomes or reduce symptoms in patients with active peripheral PsA. The study suggests that FMT may not be an effective treatment option for this condition, and future research is needed to explore its potential benefits.

Organic farming could feed Europe by 2050

A study by CNRS scientists proposes a balanced coexistence between agriculture and the environment. Implementing an organic, sustainable system involves changing diet, generalizing long crop rotation systems, and bringing together crops and livestock to reduce synthetic fertilizers and pesticides.

Pregnancy outcomes are affected by both maternal and paternal inflammatory disease

Women with rheumatoid arthritis (RA) have an increased likelihood of pre-term birth and small babies. High maternal disease activity during pregnancy strengthens these associations. In contrast, paternal inflammatory disease is associated with a higher risk of miscarriage, particularly in pregnancies conceived after the father's diagno...

Stop-motion photons: Localized light particles on the road

Scientists at the University of Rostock have made a groundbreaking discovery in the field of quantum mechanics. Localized light particles have been observed on long optical fibers, transcending the mechanism previously considered by Phil Anderson's theory of Anderson localization. This new class of disorder allows for the abrupt transp...

Paderborn University hosts 'HEART'21'

The symposium will explore the latest research findings on computer systems and methods in HPC, focusing on achieving optimal computing performance and energy efficiency. Researchers from top institutions will present their work, including keynotes and special sessions on up-to-the-minute topics.

EULAR is working to accelerate gender-equitable career advancement in academic rheumatology

The European Alliance of Associations for Rheumatology (EULAR) has established a framework to address the unmet need for support of female rheumatologists and other healthcare professionals in academic rheumatology. The framework outlines six thematic areas with 29 potential interventions to accelerate gender-equitable career advancement.

Does cannabis affect brain development in young people with ADHD? Too soon to tell, reports Harvard Review of Psychiatry

A review published in Harvard Review of Psychiatry found that cannabis use by young people with ADHD does not appear to have additional adverse effects on brain development or functioning. However, the authors note a need for further research to clarify possible effects and consider factors such as potency and frequency of use.

Picky neurons

Neurons in the mouse visual thalamus establish strong functional connections only with one retina, not with both, resolving contradictory results from previous studies. The dominant eye is determined by a clear selection of input, and non-dominant eye signals are weak or inactive.

Study: Men doing more family caregiving could lower their risk of suicide

A new study by Colorado State University Professor Silvia Sara Canetto found that men who engage in more family care work have lower suicide rates. The research suggests that men's underinvestment in family care work may contribute to their vulnerability to suicide, particularly during economic difficult circumstances.

Study examines heart and kidney outcomes of adults with nephrotic syndrome

A new study highlights the high risk of kidney failure and cardiovascular complications in patients with primary nephrotic syndrome, particularly those with focal segmental glomerulosclerosis. Adults with this condition are 19.63 times more likely to develop kidney failure over a median follow-up period of 4.5 years.

The true spread of SARS-CoV-2 infection is much greater than that observed by capturing only swab-diagnosed COVID-19 cases

A study of 300 rheumatism patients found 9% SARS-CoV-2 antibody positivity rates for IgG, IgM, and IgA, with higher titres in symptomatic patients and those with obesity and multiple comorbidities. The study confirms that the true spread of SARS-CoV-2 infection is broader than previously thought, particularly among vulnerable populations.
