The extensive training and the sacrifices athletes make to compete at the Olympic games take center stage. For Paralympians and high-performance athletes with spinal cord injuries (SCI), assessing chronic pain plays a key role in their training and readiness to compete. However, the source of chronic pain is often misattributed to acute trauma or overuse injuries. While the International Olympic Committee acknowledges pain management data among Paralympians and athletes with disabilities is limited, few studies have been launched investigating this dilemma.

Neuroscientists have sought to better understand brain function but lacked the capability to observe neuronal activity deep within the brain. Scientists have applied rational molecular engineering to develop photoacoustic probes that can be used deep within brain tissue to label and visualize neurons. This imaging approach expands significantly on what neuroscientists have been able to see with conventional light microscopy, offering the potential to report on deep neuron activity and better understand brain function.

Scientists have learned that children find it hard to focus on a task, and often take in information that won't help them complete their assignment. But the question is, why? In a new study, researchers found that this 'distributed attention' wasn't because children's brains weren't mature enough to understand the task or pay attention, and it wasn't because they were easily distracted and lacked the control to focus. It now appears that kids distribute their attention broadly either out of simple curiosity or because their working memory isn't developed enough to complete a task without 'over exploring.'

Researchers discovered that treating pancreatic cancer with a common chemotherapy drug makes immunotherapy more effective. Folinic acid elevates levels of two anti-cancer immune molecules within pancreatic tumors: natural killer T cells and type-I interferons. In mice, this led to a more effective immune response, slower tumor growth, and longer survival.

Abdominal pain associated with gallstones does not always subside after the gallbladder is removed (cholecystectomy). Even five years after surgery, one-third of patients still experience persisting abdominal pain. Additionally, some patients who do not undergo a cholecystectomy continue to have pain. These symptoms may be caused not only by the presence of gallstones but also by dyspepsia issues or irritable bowel syndrome.

A recent study explored one possible cause -- hyperoxia or high concentrations of oxygen given to such patients during surgery -- as opposed to doses more similar to air. The study concluded that hyperoxia increased oxidative stress during surgery, but this effect did not persist after surgery and did not lead to more acute kidney injury.

The study highlights the remarkable resilience of older adults (median age 86) during the COVID-19 pandemic. Disruptions to their routines led many to discover new hobbies like gardening and painting and explore virtual activities such as online yoga. While 51% experienced psychosocial issues such as anxiety and depression, 86% did not see worsening of their medical conditions and supported pandemic precautions. Despite the hardships, including the loss of residents and increased use of antidepressants and telehealth, many found joy and growth in their altered circumstances.

Detecting diseases early requires the rapid, continuous and convenient monitoring of vital biomarkers. Researchers have now developed a novel sensor that enables the continuous, and real-time detection of solid-state epidermal biomarkers, a new category of health indicators. The team's wearable, stretchable, hydrogel-based sensor overcomes the limitations of current methods that rely on biofluid samples, such as blood, urine and sweat. This makes it a promising alternative for wearable, continuous, and real-time health monitoring, facilitating the early detection of conditions such as cardiovascular diseases and stroke.

The latest research indicates that 16% to 85% of people recovering from a stroke experience at least one psychosocial symptom, including depression, anxiety, stress, fatigue and/or decreased quality of life. Critical nursing interventions, such as regular mental health screenings, education, symptom management and follow-up care, are key to reducing the negative effects on a patient's mental well-being after a stroke, yet only a small proportion of patients receive treatment.

Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation.

This surprising discovery sheds new light on how our immune system works, particularly during allergic reactions.
