(Press-News.org) Two recent studies suggest there is no significant benefit of early biologics over standard step-up care with methotrexate2,3, but these did not select for poor prognosis. The aim therefore of the SPEED trial (Severe Psoriatic arthritis – Early intervEntion to control Disease) – which was funded by the National Institute for Health Research (NIHR) – was to compare disease activity in 192 PsA patients with poor prognostic factors when treated with one of three regimens: standard step-up with conventional systemic disease-modifying anti-rheumatic drugs (csDMARD), combination csDMARD, or early induction with a tumour necrosis factor inhibitor (TNFi). The primary endpoint was the mean PsA disease activity score (PASDAS) at 24 weeks. Data were presented at the 2025 annual EULAR congress in Barcelona.
At Week 24, a difference was found in PASDAS mean scores between treatment groups, with both the combination csDMARD and early TNFi groups showing evidence of a difference when compared to standard step-up care. Of note, there was no evidence of a difference between the early TNFi and combination csDMARD groups. However, by Week 48 the benefit compared to standard step-up care was seen only for early TNFi therapy.
Presenting the work, Laura Coates said “these data show that initial intensive therapy with early biologics or combination csDMARDs are superior for rapid control of early moderate-to-severe PsA. Even with only 6 months of early biologic therapy, better outcomes are maintained at 1 year in those initially receiving a TNF inhibitor.”
A case series also presented at the congress aimed to describe real-world safety and effectiveness of combined biologic and targeted synthetic DMARD therapy in PsA. Andre Lucas Ribeiro and colleagues analysed prospectively collected data from the University of Toronto psoriatic arthritis cohort, which included 22 people treated with combinations of a bDMARD and either JAKi or TYK2i, with some patients trying multiple combinations. The primary indications for combination therapy were active peripheral arthritis and skin disease, including palmoplantar psoriasis.
Results showed numerical improvement across multiple disease-activity measures. In the bDMARD plus JAKi group, the most frequent combination was an IL-17i plus JAKi, and over 10.5 patient–years of exposure only one case of mild infectious stomatitis was reported, which did not result in treatment discontinuation. Additionally, IL-23i plus JAKi were used for 3.7 patient–years without any reported safety events.
For the bDMARD plus TYK2i group, IL-17i plus TYK2i were used for 8.5 patient-years, with one person experiencing two mild upper respiratory infections (URI) on bimekizumab plus deucravacitinib, prompting a switch for risankizumab plus deucravacitinib. IL-23i plus TYK2i were used for 8.3 patient-years, with two cases of mild URI leading to a switch to bimekizumab monotherapy, and one case of folliculitis where therapy was continued. One patient received TNFi plus TYK2i for 0.9 patient–years with no adverse events reported.
Combinations of bDMARD plus apremilast were also reported, with two cases of diarrhoea observed, but no infections.
Overall, the safety profile of bDMARD combinations with JAKi, TYK2i, and apremilast appear favourable. All reported infections were mild, managed without hospitalisation, and rarely led to treatment discontinuation. Furthermore, patients achieved short-term responses, with improvements in both musculoskeletal and skin domains. However, as this is an observational study with short-term follow-up, there is a need for randomised clinical trials to further explore and validate these findings.

New hydrogel treatments turn water waste to fertilizer
2025-06-11
By Beth Miller
Excessive nutrients in wastewater can lead to detrimental discharges into natural water bodies, prompting harmful algal blooms with severe environmental and economic repercussions. To address this pressing issue, a team of engineers in the McKelvey School of Engineering at Washington University in St. Louis has developed an innovative solution. Their novel composite nanotechnology removes and recovers nutrients from wastewater, subsequently upcycling them as agricultural fertilizers or as biorefinery feedstocks, ...
Clinical trial significantly improves detection of hidden blood clots in stroke patients
2025-06-11
LONDON, ON – A groundbreaking clinical trial led by London Health Sciences Centre Research Institute (LHSCRI) and Western University’s Schulich School of Medicine & Dentistry may enhance how medical professionals detect hidden blood clots responsible for strokes. The study, published in The Lancet Neurology, is the first to show that extending imaging to include the heart within minutes of a patient’s arrival to hospital with an acute stroke significantly improves the ability to determine the stroke’s underlying cause. This innovative diagnostic approach can be used to determine an effective and tailored treatment plan for preventing future strokes.

Survey reveals bleak job prospects for Pinoy nursing, MD graduates
2025-06-11
Ateneo de Manila University researchers warn that young Filipinos graduating with a degree in nursing or medicine face an uphill battle for stable employment, fair pay, and meaningful roles in the local public health system.
This comes as the Philippines faces a massive shortage of health professionals, with less than eight doctors per 10,000 people—below the international standard of 10 per 10,000—and over 127,000 vacancies for nurses, particularly in rural areas and private facilities.
The researchers found that many new graduates feel lost and unsupported ...
Book explores how ‘domestication’ of environmentalism limits who it protects
2025-06-11
CHAMPAIGN, Ill. — The response to a 1969 oil spill off the coast of Santa Barbara, California, reveals how the modern environmental movement has been used to protect the interests of private homeowners, said a University of Illinois Urbana-Champaign researcher.
Landscape architecture professor Pollyanna Rhee chronicled how affluent homeowners use what she calls “ownership environmentalism” to focus on protection of property and community norms, rather than society as a whole, in her new book “Natural Attachments: The Domestication of American Environmentalism, 1920–1970.”
Rhee said she was interested in examining how ...
Leading scientists: Trees and tech needed for carbon removal to help meet the 2C goal of the Paris agreement
2025-06-11
Researchers released a peer-reviewed analysis in the academic journal Climate Policy today arguing that the urgent work of removing excess carbon from the atmosphere — known as carbon dioxide removal (CDR) — can’t just rely on complex, untested techniques to capture carbon dioxide (CO2) and inject it deep underground or pump it into the ocean. Rather, they show that nature-based solutions, which include restoring forests and other ecosystems that capture atmospheric CO2 using the ancient biochemical process ...
New study from landmark trial suggests avocados may play a role in sleep, a key factor in cardiovascular health
2025-06-11
MISSION VIEJO, Calif. (June 11, 2025) – A new study suggests that eating one avocado a day may positively impact sleep. Science now confirms sleep is as important for good health as nutrition and exercise. In a secondary analysis of the largest randomized controlled trial on avocados to date, researchers found adults who consumed one avocado daily for six months reported better sleep compared to those who ate fewer than two avocados per month.
As, per the CDC, getting enough sleep can help lower the risk factors for heart disease, these findings add to a growing body of evidence supporting avocados as a heart-healthy food and mark the first time avocado consumption ...
How flies grow their gyroscopes: Study reveals how flight stabilizers take shape
2025-06-11
A team from the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and the Miguel Hernández University (UMH) in Elche, has revealed how a structure essential for fly flight, the haltere, is formed. This small organ, located behind the main wings, functions as a biological gyroscope that helps the insect stay stable in the air. The study, published in the journal Current Biology, was led by researcher José Carlos Pastor Pareja, head of the Cell-to-tissue architecture in the nervous system laboratory at the IN.
This work shows that, contrary to previous ...
Researchers find that, overall, prescribing ADHD medications via telehealth does not alter risk of substance use disorder
2025-06-11
Telehealth patients were not more likely to develop substance use disorder
Researchers found that a small number of people who received initial stimulant prescription via telehealth developed stimulant disorder and emphasize the importance of follow-up care
Telehealth can make health care easier to access for patients with attention-deficit/hyperactivity disorder (ADHD) who need treatment, but experts worry about an increased risk of substance use disorder for patients being prescribed controlled medications such as stimulants for ADHD during these appointments. Mass General Brigham researchers scrutinized this concern with the first-ever study comparing ...
How trace elements are recycled in the deep sea
2025-06-11
The oceans are full of living things, with microscopic algae (phytoplankton) at the base of the marine food chain. These organisms make a living in the same way as land plants, using the sunlight that penetrates the upper 100 meters or so of the ocean as the energy source by which they synthesise organic matter for their cells. Every year, these tiny algae make about as much organic carbon as land plants. Like land plants, they obtain the building blocks of their cells from the surrounding environment – not a soil in this case but the seawater solution they live in.
But unlike the land ecosystem, when these algae die, they fall into the dark ...
Cyborg tadpoles with soft, flexible neural implants
2025-06-11
Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a tadpole embryo’s neural plate, the early-stage, flat structure that folds to become the 3D brain and spinal cord.
The researchers demonstrated that the device could integrate seamlessly into the brain as it develops and record electrical activity from single brain cells with millisecond precision, with no impact on normal tadpole embryo development or behavior.
These so-called cyborg tadpoles offer a glimpse into a future in which profound mysteries of the brain could be illuminated, ...
