This paper introduces a newly digitized, open-access version of the Food and Drug Administration's "Orange Book"-a linkage between approved small-molecule drugs and the patents that protect them. The Orange Book also reports any applicable regulatory exclusivity that prevents competitive entry. We summarize the Orange Book's coverage and discuss the opportunities and challenges associated with using these data for research.

Aim: To synthesise research on the view of the public and patients of the use of artificial intelligence (AI) in radiology investigations.

Methods: A literature review of narrative synthesis of qualitative and quantitative studies that reported views of the public and patients toward the use of AI in radiology.

Results: Only seven studies related to patient and public views were retrieved, suggesting that this is an underexplored area of research.

Background: The cancer burden falls predominantly on older (≥65 years) adults. Prompt presentation to primary care with cancer symptoms could result in earlier diagnosis. However, patient symptom appraisal and help-seeking decisions involving cancer symptoms are complex and may be further complicated in older adults.

The modern regime for balancing innovation and competition in pharmaceuticals was established through the Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Act. This regime needs updating. The process that Hatch-Waxman established for listing patents and challenging patents on the Food and Drug Administration's Orange Book is one important area for reform.

Many cancer referral guidelines use patient's age as a key criterium to decide who should be referred urgently. A recent rise in the incidence of colorectal cancer in younger adults has been described in high-income countries worldwide. Information on other cancers is more limited.

Background: Older age and frailty increase the risk of morbidity and mortality from cancer surgery and intolerance of chemotherapy and radiotherapy. The effect of old age on diagnostic intervals is unknown; however, older adults need a balanced approach to the diagnosis and management of cancer symptoms, considering the benefits of early diagnosis, patient preferences, and the likely prognosis of a cancer.

Aim: To examine the association between older age and diagnostic processes for cancer, and the specific factors that affect diagnosis.

Propofol infusion syndrome is a rare, potentially fatal condition first described in children in the 1990s and later reported in adults. We provide a narrative review of what is currently known about propofol infusion syndrome, including a structured analysis of all published case reports; child and adult cases were analysed separately as propofol is no longer used for long-term sedation in children. The review contains an update on current knowledge of the pathophysiology of this condition along with recommendations for its diagnosis, prevention, and management.

Observers worry that generic patent challenges are on the rise and reduce the effective market life of drugs. A related concern is that challenges disproportionately target high-sales drugs, reducing market life for these "blockbusters." To study these questions, we examine new data on generic entry over the past decade.
