As befitting someone whose life’s work was to enable patients to have a good death, Robert Twycross had mapped out his own to the last detail. Every aspect of his funeral was planned. The day before he died he was dictating messages to publishers about a forthcoming textbook. He had even told one of his daughters the day he was most likely to die—and he was right. More importantly, says his eldest daughter Alison Twycross, who was with him as he died, his final hours were as he would have advocated. “Dad died very peacefully in a way that I wish everyone could achieve,” she said. “He was ready. He was at home, pain free, and his family were around him—it was a good death.” Apart from Cicely Saunders, founder of the modern hospice movement, “I don’t think there has been anyone else that has made such a sustained and major contribution to palliative care,” said Andew Wilcock, long term mentee, writing partner, and friend. “He leaves a profound legacy that continues to influence how end-of-life care is provided around the world.

When choosing to specialise in cardiology, Rob Egdell worried that he was taking the easy route as he enjoyed it so much “I dabbled with lots of other complicated things, but always came back to cardiology,” says Rob Edgell. “I was worried that something I enjoyed and found straightforward might get boring. But if you enjoy it, you do it with vigour and energy, and you’re fulfilled by it.” That he made this choice is clearly a relief to the consultant cardiologist at East Cheshire NHS Trust in Macclesfield—he has loved caring for cardiac patients ever since. It also prompts him to recommend to resident doctors that they choose a specialty they enjoy. “Even when you’re focused on the end game of becoming a consultant or a GP, training is a long process and you can’t really go through it as a sort of period of purgatory,” he advises. “You have to enjoy what you’re doing or life feels miserable, and …

We need to redesign social media and other digital platforms so that these spaces are safer and healthier, writes Louise Holly Across the globe, countries are grabbling with how to shield children from the dangers of the digital world. One idea is to prevent children from accessing the most harmful digital spaces. Australian has just introduced a bill to parliament proposing to ban children under 16 from using social media.1 If passed, it would make Australia the first country in the world to have such strict legislation. Mitigating the physical and mental health risks posed by digital platforms is an urgent public health priority that governments need to engage with, but limiting children’s online participation will not tackle the root causes of these harms. Australia’s proposed law will make it illegal for anyone under 16 to have a social media account and wouldn’t have exemptions for parental consent. Companies such as Meta, ByteDance, and Google will be responsible for checking that users are not under 16 and could face penalties if they fail to comply.2 If the law is passed, it wouldn’t take effect for over a year, …

Of the various types of academic misdemeanours and felonies, perhaps plagiarism is the most difficult and complex to study and write about. Even defining it is difficult. The US Office of Research Integrity (ORI) defines plagiarism as “the appropriation of another person's ideas, processes, results, or words without giving appropriate credit,” but how do you define when it has occurred? What are the quantitative and qualitative thresholds? What are the different types of plagiarism? Why does plagiarism occur? How does one detect it? What is self-plagiarism and should we even call it that? There is an enormous literature on the subject and it needs to be tamed; an annotated bibliography would help, if anyone would create one. Perhaps they already have? The third member of the academic felonies trio, after fabrication and falsification, which I have previously discussed,12 is plagiarism. It may not seem obvious, but the origin of the word “plagiarism” is buried in the hypothetical IndoEuropean root PLĀK, meaning flat. The Greek word πλάξ meant a flat plate, from which we get “placoid” an adjective referring to the type of scale that covers certain cartilaginous fishes, of the order Placoidei, including sharks and rays, now known as Elasmobranchii, ἐλασμός being a beaten out metal plate. Another group of fishes, now extinct, with flat bony plates encasing the head and thorax, went under the name of placoderms. Other flat words that come from the same root include placenta, which in Latin meant a flat cake, and leukoplakia, the flat white precancerous patches that are sometimes seen covering mucous membranes, typically in parts of the mouth and on the vulva, where it is also called lichen sclerosus or kraurosis vulvae (Greek κραῦρος brittle, dry); in men it can affect the penis, when it is known as balanitis xerotica …

The temptations of doctors to act inappropriately are many and well documented. They include, among others, the temptation to put financial gain before patient wellbeing, to cut corners to reduce workload, to cover up errors for self-preservation, to speak ill of patients and colleagues in moments of frustration, and to engage in improper relationships with patients. Far less discussed are the temptations towards wrongdoing of medical students which, although usually less dramatic in nature, are nonetheless rife. Medical students are for the most part high achieving students, accustomed to success and in fear of failure. At medical school, they tend to have one overriding goal, which is to pass their exams and qualify as doctors. The desire to pass is so intense that it leaves them prone to the temptation of wrongdoing in order to secure a pass.

The response to the Olympian’s call for wider access to prostate cancer screening has been largely uncritical, Margaret McCartney finds Media coverage has been rightly sympathetic to Chris Hoy, one of the most successful cyclists in history, who recently disclosed that he has metastatic prostate cancer. The press has also taken up Hoy’s call that more men should be tested for the disease. He told the BBC that the age at which men can obtain a prostate specific antigen (PSA) test should be reduced from 50. “It seems a no-brainer,” he said. “Why would they not reduce the age? Bring the age down and allow more men to go in and get a blood test.”1 In a commentary the Independent said that Hoy’s intervention could save thousands of lives: “Some 12 000 men die from prostate cancer each year, many after begging their doctors to be tested—after which they are told they only have months to live. The Olympic cyclist’s call for a rethink of GP screening could be a game-changer.”2 The health and social care secretary, Wes Streeting, told the BBC that Hoy made a “powerful” …

Tom Nolan reviews this week’s research When it comes to peripherally inserted lines for outpatient parenteral antimicrobial therapy (OPAT), where should one draw the line? Midline catheters, which end in peripheral veins, are thought to offer lower risks of infection and thromboembolism than peripherally inserted central catheters (PICCs). A new cohort study supports this, finding that, for a device dwell of 14 days or less, midline catheters were associated with a lower risk of major complications (0.9% v 5.3%, adjusted hazard ratio 0.29 (95% CI 0.12 to 0.68)). However, the study design means that confounding by indication—whereby lower risk patients received a midline catheter—is hard to measure and exclude.

汤姆-诺兰（Tom Nolan）回顾本周研究 当谈到用于门诊肠外抗菌治疗（OPAT）的外周插入管路时，应该在哪里划线？与外周置入中心静脉导管（PICC）相比，末端位于外周静脉的中线导管被认为具有更低的感染和血栓栓塞风险。一项新的队列研究证实了这一点，该研究发现，在设备停留时间为 14 天或更短的情况下，中线导管发生重大并发症的风险较低（0.9% 对 5.3%，调整后危险比为 0.29（95% CI 0.12 至 0.68））。然而，研究设计意味着很难测量和排除适应症的混杂因素，即风险较低的患者接受中线导管。JAMA Intern Med doi:10.1001/jamainternmed.2024.5984 社论建议，不要等到前列腺癌确诊后才考虑预期寿命 ...
