AMR: Over 400 antibiotic resistant infections were reported every week in England last year
Antibiotic resistant infections in England continued to rise in 2025, national surveillance data have shown.1The UK Health Security Agency (UKHSA) said that a total of 21 129 antibiotic resistant bacteraemia cases were reported in England in 2025, up 16.8% from 18 086 in 2019. An average of 406 cases were reported every week.Although resistant infections are still rising, the pace of that increase slowed in the past year, the new UKHSA report showed.Between 2024 and 2025, cases only rose by 3.2%, from 20 468 to 21 129. This is about a third of the 9.3% rise in cases between 2023 and 2024 (18 732 to 20 468).There has also been further progress in reducing antibiotic use in the NHS, the UKHSA said, including efforts to promote best prescribing practices and responsible use of these drugs.Between 2019 and 2025, total antibiotic use in the NHS decreased by 10.7%, from 17.8 to...

Heatwaves: Ambulances hit hardest as many delayed seeking care, analysis finds
Boosting ambulance capacity should be prioritised during heatwaves, as they faced the most immediate pressure during this year’s sweltering temperatures, a new analysis concludes.However, all healthcare services, including emergency care and general practice, must be better equipped to deal with demand after heat surges, the report by the King’s Fund says.Many patients delayed seeking care on the hottest days during this summer’s record breaking heatwaves but then sought treatment afterwards, the think tank’s analysis found.NHS officials said that this summer was the busiest ever for the health service. In June officials issued “red” heat health alerts, which are reserved for the most life threatening events.1Last month health leaders told The BMJ that the NHS was now facing a twin summer and winter crisis requiring an equal level of planning because of the pressure on services.2The King’s Fund used daily activity data to show how this summer’s heatwaves affected the healthcare...

Effect of intensive blood pressure control on cognitive outcomes and brain structures in adults with type 2 diabetes: prespecified analysis of secondary outcomes of BPROAD randomised controlled trial
AbstractObjectiveTo evaluate the effect of intensive compared with standard treatment of systolic blood pressure (SBP) on cognitive outcomes and brain structures in adults with type 2 diabetes.DesignMulticentre, open label, outcome assessor masked, randomised controlled trial.Setting145 clinical centres across seven geographical regions in China.Participants12?821 adults aged ?50 years with type 2 diabetes, raised SBP, and increased cardiovascular risk, of whom 12?434 without probable dementia at baseline were included in this cognitive ancillary study. Further assessments were performed annually and at the end of study.InterventionsParticipants were randomly assigned to receive intensive treatment targeting SBP <120 mm Hg or standard treatment targeting SBP <140 mm Hg for up to five years.Main outcome measuresThe primary cognitive outcome was a composite of all cause dementia or mild cognitive impairment. Secondary cognitive outcomes included all cause dementia, mild cognitive impairment, changes in cognitive functions, and changes in brain magnetic resonance imaging (MRI) characteristics. A subset of participants underwent brain MRI at baseline (n=862) and at the end of study (n=605) to assess changes in white matter lesion volume and total brain volume.Results6219 participants were assigned to receive intensive treatment and 6215 to receive standard treatment. Baseline mean age was 63.7 years, and 5567 (44.8%) participants were women. After one year, mean SBP was 121.6 mm Hg in the intensive treatment group and 133.2 mm Hg in the standard treatment group. During a median follow-up of 3.8 years, the primary cognitive outcome of all cause dementia or mild cognitive impairment occurred in 747 participants (3.69 events per 100 person years) in the intensive treatment group and 783 participants (3.89 events per 100 person years) in the standard treatment group (hazard ratio 0.96, 95% confidence interval (CI) 0.86 to 1.06; P=0.38). In the MRI substudy (428 intensive treatment v 434 standard treatment), the intensive treatment group had a smaller increase in white matter lesion volume compared with the standard treatment group (between group difference ?0.09 inverse hyperbolic sine (asinh) transformed cm3, 95% CI ?0.15 to ?0.02; P=0.01).ConclusionsOver a median of about four years, no statistically significant difference in incidence of a composite of all cause dementia or mild cognitive impairment was observed among adults with type 2 diabetes receiving standard treatment of SBP (target <140 mm Hg) and intensive treatment (target <120 mm Hg). Intensive treatment was, however, associated with a reduction in the accrual of cerebral white matter lesion volume.Trial registrationClinicalTrials.gov NCT03808311.

Kay Dickersin: pioneer of evidence based medicine and a founder of the Cochrane Collaboration
bmj;395/nov12_7/e101440/F1F1f1In 1987 Kay Dickersin and her colleagues published a short study with an uncomfortable finding.1 They had asked 318 authors of published randomised trials whether they had also taken part in trials that were never published. Among the completed but unpublished trials, 14% favoured the new treatment; among the published ones, 55% did. Editors were not chiefly to blame: most unpublished trials had simply never been written up and submitted, usually because the results were negative—meaning that they failed to reject the null—or were uninteresting.If trials showing benefit are more likely to reach print than those showing no effect or harm, then reviews, meta-analyses, guidelines, and the clinicians who rely on them will overestimate benefits and underestimate harms. Patients receive treatments that work less well than believed, and the contribution of trial participants who accepted risk for the common good is wasted.Dickersin later showed that bias also operates inside published...

What Brazil’s leftist win means for the world’s biggest universal health system
Public health experts and researchers in Brazil breathed a sigh of relief on 25 October after Luiz Inácio Lula da Silva overturned a deficit of 2.2 million votes in the first round of presidential elections to defeat Flávio Bolsonaro by more than 4.4 million votes in the runoff.The historic comeback against Flávio Bolsonaro—son of former president Jair Bolsonaro—made Lula the first candidate since Brazil resumed direct presidential elections in 1989 to lose the first round and go on to win the presidency. The surprise result also bucked a Donald Trump backed regional shift to the right, with seven right wing leaders elected across Latin America since 2025.As the octogenarian leftist gave his victory speech in São Paulo, he told supporters that the desire to protect Brazil’s national health system, the Sistema Único de Saúde (SUS), had helped drive his comeback.“I want you to know that one of the things that...

Changes to Prevent guidance on radicalisation: what you need to know
What is Prevent?Prevent is part of Contest, the UK’s counterterrorism strategy. It is underpinned by the Counter-Terrorism and Security Act 2015.Its aim is to prevent terrorist threats by identifying and intervening with people at risk of radicalisation before they commit violent acts.What is the Prevent duty?Everyone working in a healthcare setting has a duty to ensure that they understand Prevent and know what to do if someone they have had contact with is at risk of radicalisation.The Prevent duty sits alongside established safeguarding duties on healthcare professionals to protect people from a range of other harms, such as sexual exploitation.What role do mental health staff play?If a professional in a mental health service has concerns about someone who may be susceptible to radicalisation, they should consider making a referral to Prevent.Referrals are assessed by the police and, where appropriate, progressed to a multi-agency Channel panel that can include the police,...

Surrogate outcomes in clinical research
A patient can live longer, feel better, or function better—these are direct, patient relevant clinical outcomes.1 Surrogate endpoints, in contrast, are indirect measures intended to predict such benefits. They can be used to shorten the duration of trials and make treatments available sooner, but that comes at the cost of greater uncertainty: improving a surrogate may not improve what ultimately matters to patients.A linked article by Lo and colleagues (doi:10.1136/bmj-2026-100618) presents the REASSurE framework for evaluating a single surrogate against a clinical endpoint.2 Developed through a Delphi survey, consensus meeting, piloting, and finalisation, the framework deserves credit for its transparent methods and reporting. It provides a structured checklist of mandatory or recommended items across four areas. Joint evaluation of multiple surrogates remains outside its scope.REASSurE aims to go beyond existing approaches, including the IQWiG (Institute for Quality and Efficiency in Health Care) framework,3 the Biomarker-Surrogacy Evaluation Schema,4 and the three-level...

What doctors search for . . . and other research
US Military mightAs most GPs know from bitter experience, requesting testosterone levels on healthy men creates a lot of extra worry and work, without clinical benefits. In July, US Defence Secretary Pete Hegseth controversially announced that US military personnel aged 30 years and older would be required to have annual testosterone screening. Researchers have estimated how many low testosterone concentration, or low T, results army medics will need to churn through, using cross sectional data from the Military Health and Nutrition Examination Study. Analysing morning testosterone levels from 479 men with a mean age of 30, they estimated that one in four active duty US Army personnel would have a morning testosterone below the American Urology Association’s cut off of 300 ng/dL (10.4 nmol/L). Scaled up to the whole US army, that’s 100 000 positive results.JAMA doi:10.1001/jama.2026.19794What doctors search forOpenEvidence is marketed as an AI copilot for doctors and claims...

How cells die . . . and other stories
Sleep and illnessWhen investigators interrogated accelerometer data from 96 000 UK Biobank participants, they found links between quality of sleep and the incidence of 156 different conditions (Plos Med doi:10.1371/journal.pmed.1005213). On the whole, more REM (rapid eye movement) and deep sleep were associated with lower risk of disease, while sleep irregularity and wakefulness after sleep onset were associated with higher risk. But it’s far from clear whether disturbed sleep contributes to illness or is an early sign of it.GLP-1 drugs and anaesthesiaGlucagon-like peptide 1 (GLP-1) receptor agonists delay gastric emptying, potentially increasing the risk of regurgitation and aspiration during anaesthesia. In a prospective study of 47 000 patients undergoing anaesthesia in UK hospitals, 2.9% were taking these drugs (Anaesthesia doi:10.1111/anae.70380). Regurgitation or pulmonary aspiration occurred in 1.41% of users, compared with 0.12% of non-users. Most events involved regurgitation rather than aspiration.Congenital infections and neurodevelopmentTORCH infections are a group of congenital...

Harnessing the personal health data explosion
Smart watches, health and fitness apps, and social media have fuelled an explosion in people’s access to health information about themselves and other people. Yet as these innovations serve up ever more individual data, and the reach of influencers and entrepreneurs on social media expands, so the challenges facing health workers accumulate.With social media awash with inaccurate posts about health, should doctors be wading in to offer medical advice or to correct misinformation? When influencers are pushing iron or testosterone supplementation to their followers (doi:10.1136/bmj-2026-101080 doi:10.1136/bmj-2026-101300),12 do doctors need to be more active in outlining the risks and benefits? Our feature on “medfluencers” finds doctors arguing the case for engaging directly with influencers on social media, while others warn about the potential regulatory pitfalls (doi:10.1136/bmj-2026-101156).3 John Dale-Skinner, a medicolegal adviser at the Medical Defence Union, says that he would steer doctors “away from that minefield.”People understandably want to impose some...

Mass in the liver
A woman in her 30s presented with a six hour history of epigastric pain. She described a sudden onset tearing sensation which developed into a constant sharp pain of eight out of 10 severity, accompanied by pre-syncopal symptoms. She had no relevant medical history.Her blood pressure was 93/58 mm Hg. Vital signs were otherwise normal.Physical examination showed right upper quadrant tenderness and a firm mass at the inferior pole of the liver. Initially, a ruptured liver tumour or liver vascular malformation with haemorrhage was suspected.Liver function and serum tumour markers were tested and showed mildly raised levels of alkaline phosphatase (121.96 U/L; reference 35-100 U/L) and markedly raised levels of alpha fetoprotein (AFP) (2603.78 ng/mL; reference < 9 ng/mL).High levels of AFP raised suspicion of hepatocellular carcinoma (HCC). Abdominal computed tomography showed a cystic solid mass in the right hepatic lobe with capsular rupture and pericapsular fluid (fig 1). Biopsy...

Big tobacco is shifting to big addiction and must be curbed
Decades of progress in reducing global tobacco use have come under threat in the past 15 to 20 years because of the multibillion dollar tobacco industry’s backlash against efforts to move beyond controlling the tobacco epidemic to ending it—the “endgame” concept.1 Despite this hiatus, recent developments suggest that an endgame is achievable, but only if governments step up to the mark.In 2025, for example, the Maldives became the first country to implement a tobacco-free generation policy, a birthdate based sales restriction designed to prevent future generations taking up smoking.2 In 2027, the UK is set to become the second through its Tobacco and Vapes Act.2 Both legislative measures also seek to counter the rapid increase in non-therapeutic nicotine (NTN) use, with the Maldives going further by stopping the import and sales of e-cigarettes.2While positive, these developments23 show that endgame policies must now extend beyond tobacco to address NTN products. The...

Thousands of patients automatically deleted from electronic referral service, watchdog warns
Patients waiting for specialist care were dropped off the electronic referral service (e-RS) without warning, a national safety watchdog has warned.A Health Services Safety Investigations Body (HSSIB) report earlier this month found that from February to July 2026 over 120 000 referrals, including advice and guidance requests and referrals for review, disappeared from the e-RS.1The watchdog warned that these disappearances came to light only after GPs raised the alarm that patients had not heard from a provider about their referrals and otherwise might have been missed.The HSSIB’s report found no evidence of patients being harmed because of these referral disappearances. However, it acknowledged concerns that some patients could have avoided invasive treatment had they been seen earlier.The e-RS is a web based digital platform supplied by NHS England for referring patients to specialist providers.Responding to the HSSIB’s report, NHS England said that the e-RS was not designed for current referral...

Rama Shanker Singh
bmj;395/oct30_11/e101174/F1F1f1Rama (known to many of his UK colleagues as “Ron”) was born in Bihar, India, in 1949. His father was an acclaimed general surgeon and, after Rama’s mother died suddenly, he was raised by his beloved second mother, a nurse. The eldest of four siblings, he was raised in Patna, a historic city on the banks of the Ganges. There he attended St Xavier School before transferring to Darbhanga for further college. In his teens he developed a lifelong passion for cinema and at one stage was keen to be an actor himself, before deciding to devote his life to medicine.He graduated from Darbhanga Medical College, Bihar, in 1972. He obtained his masters in general surgery in 1976 and moved to the UK in 1979. He worked in various hospitals and was subsequently appointed as a consultant in emergency medicine at Withybush General Hospital in Wales. From there he moved...

Healthwatch: Plans to abolish patient watchdog are scrapped in government U turn
Ministers have scrapped plans to abolish Healthwatch England and local Healthwatch groups, after pushback from health leaders and organisations.Launched in 2012, Healthwatch functions as a statutory independent voice for patients, helping the public hold the NHS accountable and push for patient centred improvements.Plans to abolish the Healthwatch network, consisting of 153 local groups and the national body Healthwatch England, were introduced as part of the Health Bill in May,1 amid wider governmental efforts to “simplify the patient safety landscape” of the NHS.It was proposed that the functions of the local Healthwatch organisations would be transferred to NHS integrated care boards, while the role of Healthwatch England would be transferred to the Department of Health and Social Care.2 This would mean an increased reliance on the NHS App for patient feedback. But critics warned that a loss of independence would have led to “health and care services marking their own homework.”Now,...

Hundreds of GP websites crash after online provider enters administration
“Questions must be asked” about the lack of warning before hundreds of practice websites went offline after an online provider entered administration, GP leaders say.They have also questioned why there doesn’t seem to be a coordinated national contingency plan for the failure of a provider delivering critical NHS infrastructure.Hundreds of general practice websites in England and Wales suddenly went offline on 28 October after their online provider—Silicon Practice—entered administration.The software company claimed on its website to provide services for more than 1000 general practices.NHS England said that less than 500 practices had been affected—under 10% of the total number of practices in England and Wales.Reacting, Sarah Jacques, GP co-lead of the Doctors’ Association UK. said: “The sudden loss of websites and online consultation services across hundreds of [general] practices is deeply concerning.”“These are no longer optional extras; they are essential routes through which patients access care.”A notice of administration was...

RCGP does U turn on policy that put assisted dying on par with arms dealers
An “ethical policy” that prevented assisted dying campaign groups from hosting events at the Royal College of General Practitioners will be “reviewed and amended,” the college pledged today.This reversal comes after the campaign group Dignity in Dying was prevented from hosting a GP led event at the college’s London headquarters, prompting outrage among RCGP members and terminally ill patients.Dignity in Dying said that terminally and incurably ill people had hoped to share their experiences with clinicians, parliamentarians, and policy makers at the event.Until Thursday the RCGP website listed assisted dying alongside various groups and industries, including those involved in arms manufacturing, adult entertainment, and fossil fuel exploration, that are banned from holding events at the college’s 30 Euston Square headquarters.1“30 Euston Square is not permitted to accommodate meetings, events, or corporate membership from any organisation engaged with assisted dying or any event where its purpose is to promote and lobby...

The UK should invest in healthy lifestyles rather than drugs
The BMJ’s analysis of Mounjaro’s cost to the NHS is fascinating.1 Kudos to the drug industry for finding a true and perhaps never ending El Dorado. There is no shortage of obese people with medical problems or those with body image issues in need of a quick fix.But the NHS expenditure, representing government expenditure or our tax money, is sadly also a quick fix—£574m a year could fund six Olympic velodromes in six cities in the UK (based on figures from 2011).2 It could also fund approximately 5740 high quality tennis courts in state schools across England.3 Investing in health, in sport, and in young people is more likely to produce sustained impact in the effort to tackle the obesity epidemic.The complex interplay between eligibility, affordability, and effectiveness is likely to be exploited by the drug industry. But as a nation, our preference should be for a healthy, active lifestyle...

Protecting workers from increasing heat
Climate change is increasing the frequency, intensity, and duration of hazardous heat, particularly in tropical and subtropical regions, and strong El Niño conditions may push temperatures even higher.12 An estimated 2.41 billion workers are exposed to excessive heat each year, contributing to 22.85 million injuries and 18 970 deaths.3 A meta-analysis of 111 studies from 30 countries and more than 40 occupations found that 35% of workers exposed to heat experienced heat strain and 30% reported productivity losses.4 In 2024, heat caused an estimated 639 billion lost working hours and $1.09tn in lost income.1Temperature is not the only determinant of heat risk. Humidity, radiant heat, air movement, workload, clothing, exposure duration, and acclimatisation interact with access to water, sanitation, shade, and recovery time.The burden is unequal; those with the least bargaining power and weakest protection face the greatest risks. Around two billion people work informally worldwide, often beyond the reach...
