(Press-News.org) A new editorial in Biocontaminant reports that Guangdong Province is experiencing the largest outbreak of chikungunya fever ever recorded in China, with more than 4,000 confirmed cases since late July. Shunde District of Foshan alone has reported over 3,600 infections, and cases have also spread to Guangzhou, Shenzhen, Hong Kong, and Macao.
Chikungunya fever is transmitted by Aedes mosquitoes, the same vectors responsible for dengue and Zika. The disease, marked by fever and severe joint pain, does not spread directly between people, making mosquito control the key to prevention.
“The outbreak reflects both the global spread of chikungunya and the favorable conditions for mosquito-borne diseases in southern China,” said lead author Guang-Guo Ying of South China Normal University.
Authorities have launched a province-wide campaign urging residents to remove stagnant water and reduce mosquito breeding sites. The editorial also stresses that climate change, urbanization, and global travel are expanding the reach of arboviruses worldwide, posing growing public health challenges.
The World Health Organization has recently introduced updated clinical guidelines and reinforced its Global Arbovirus Initiative to strengthen monitoring, prevention, and coordinated response. The authors call for investment in genomic surveillance, community engagement, and international cooperation to mitigate future outbreaks.

Tirzepatide improves blood sugar control in children aged 10-17 years with type 2 diabetes inadequately controlled on existing therapies (SURPASS-PEDS trial)
2025-09-18
New research shows that that the diabetes/obesity medication tirzepatide can cause clinically meaningful improvements in blood sugar control and weight loss in children and adolescents with type 2 diabetes aged 10-17 years whose diabetes and weight are inadequately controlled with an existing treatment regimen of metformin, insulin, or both.
The study (the SURPASS-PEDS trial), by Dr Tamara Hannon, Division of Pediatric Endocrinology and Diabetology, Indiana University School of Medicine, Indiana University School of Medicine, Indianapolis, ...
An old drug, in a low dose, shown to be safe and effective in preventing progression of type 1 diabetes in children and young people (MELD-ATG trial)
2025-09-18
New research presented at this year’s Annual Meeting of the European Association for the Study of Diabetes (EASD) in Vienna, Austria (15-19 September) and published simultaneously in The Lancet shows that a much lower dose than previously thought of the old immunomodulatory drug anti-thymocyte globulin (ATG) is safe and effective in preventing progression of type 1 diabetes (T1D) in young people.
The authors, led by EASD President Professor Chantal Mathieu, Department of Endocrinology, UZ Leuven, Belgium, say that the trial findings open up the potential use of this affordable, repurposed agent, ATG, in a low and safe dose, as ...
Study reports potential effects of verapamil in slowing progression of type 1 diabetes
2025-09-18
New research (the Ver-A-T1D trial) presented at this year’s Annual Meeting of the European Association for the Study of Diabetes (EASD) (Vienna, 15-19 September) shows that slow-release (SR) verapamil (360mg daily) could have a potential effect on beta-cell function in adults with newly diagnosed type 1 diabetes. The study is led by Professor Thomas R. Pieber, Medical University of Graz, Austria, on behalf of the Ver-A-T1D Study Group.
Type 1 diabetes (T1D) is a chronic autoimmune disease where the body's immune ...
Fresh hope for type 1 diabetes as daily pill that slows onset confirms promise at 2-year follow-up
2025-09-18
In 2023, the groundbreaking Australian BANDIT (Baricitinib in New Onset Type 1 Diabetes) trial [1] reported that a daily pill of baricitinib, commonly prescribed for rheumatoid arthritis and alopecia, could safely preserve the body’s own insulin production and slow the progression of type 1 diabetes (T1D) in people recently diagnosed with the condition.
Now the follow-up of the blinded BANDIT trial, being presented at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Vienna ...
New estimates predict over 4 million missing people who would be alive in 2025 if not for inadequate type 1 diabetes care
2025-09-18
The global type 1 diabetes (T1D) burden continues to increase rapidly driven by rising cases, ageing populations, improved diagnosis and falling death rates, according to the results of a new modelling study being presented at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Vienna (15-19 Sept).
The study estimates that T1D will affect 9.5 million people globally in 2025 (up by 13% since 2021), and this number is predicted to rise to 14.7 million in 2040. However, due to lack of diagnosis and challenges in collecting sufficient data, the actual number of individuals living with T1D is likely much higher, researchers say.

So what should we call this – a grue jay?
2025-09-18
Biologists at The University of Texas at Austin, who have reported discovering a bird that’s the natural result of a green jay and a blue jay’s mating, say it may be among the first examples of a hybrid animal that exists because of recent changing patterns in the climate. The two different parent species are separated by 7 million years of evolution, and their ranges didn’t overlap as recently as a few decades ago.
“We think it’s the first observed vertebrate that’s hybridized as a result of ...
Chicago Quantum Exchange-led coalition advances to final round in NSF Engine competition
2025-09-18
A Chicago Quantum Exchange–led coalition focused on leveraging cutting-edge quantum technology to protect the nation’s most sensitive information from cyber attacks has advanced to the final stage of the National Science Foundation Regional Innovation Engines (NSF Engines) program, the NSF announced Thursday afternoon.
If funded, Quantum Connected, a Midwest-based coalition of academic, industry, nonprofit, and government partners, will build critically needed quantum-based cyber security. It is one of 15 teams who will pitch the NSF on different projects. Winners, anticipated to be announced in early 2026, could receive as much as $160 million ...
Study identifies candidates for therapeutic targets in pediatric germ cell tumors
2025-09-18
A study conducted by the Molecular Oncology Research Center (CPOM) at Hospital de Amor in Barretos (formerly Barretos Cancer Hospital) in the state of São Paulo, Brazil, has identified possible biomarkers that could guide the development of more personalized therapies for pediatric germ cell tumors (GCTs). Although GCTs account for only 3% of childhood cancers, they challenge doctors and researchers due to their diversity and the toxicity of available treatments.
The main approach today involves surgery combined with chemotherapy. ...

Study illuminates contributing factors to blood vessel leakage
2025-09-18
OKLAHOMA CITY – A new study from the University of Oklahoma reveals how a little-understood protein, CD82, contributes to blood vessel leakage, a process that initiates inflammation but becomes dangerous when it occurs during severe inflammatory diseases such as sepsis, acute respiratory distress syndrome and COVID-19. The findings, published in Nature Cardiovascular Research, could open the door to new therapies aimed at protecting patients from multi-organ failure and death in severe and systemic inflammation.
Blood vessel (vascular) leakage happens when blood vessels ...
