Urgent suspected cancer (“red‑flag”) referrals were designed around speed because time to diagnosis and treatment initiation is a determinant of survival in multiple malignancies. Yet many services across England now report median waits that approach or exceed seven weeks from referral to first specialist assessment or diagnostic completion. The clinical concern is not abstract: even modest system‑level delays are consistently associated with measurable increases in mortality when they postpone curative surgery, radical radiotherapy, or systemic therapy. In multi‑tumour meta‑analytic evidence, each four‑week delay in initiating treatment is linked to a clinically relevant rise in mortality for surgery and radical radiotherapy, underscoring the need to compress pathways wherever possible. Backlogs stem from a confluence of causes: pandemic‑era disruptions to endoscopy, imaging, and theatre schedules; workforce shortages in radiology, pathology, endoscopy, and oncology; rising referral volumes driven by awareness campaigns and guideline broadening; and entrenched capacity–demand mismatches in high‑throughput diagnostics. Importantly, evidence indicates that building capacity is unlikely to provoke a short‑term surge in unnecessary referrals; instead, it can relieve structural bottlenecks without materially changing general practice behaviour. This analysis synthesises high‑quality evidence on time‑to‑treatment effects, models how diagnostic delays alter stage and survival, and outlines practical mitigation strategies the NHS can deploy now—spanning triage tools like faecal immunochemical testing (FIT), rapid diagnostic centre (RDC) models, and targeted technology adoption—to compress pathways safely while protecting outcomes.

England and Wales will introduce a free universal childhood varicella (chickenpox) vaccination programme beginning January 2026. This policy aligns the UK more closely with countries that have already reported substantial reductions in varicella incidence, hospitalizations and school outbreaks following universal childhood vaccination. Policymakers have weighed expected gains against long-discussed concerns about potential medium-term changes in herpes zoster (HZ, shingles) epidemiology due to reduced “exogenous boosting” of adult immunity. Dynamic modeling tailored to England and Wales projects large, durable reductions in varicella burden with universal vaccination, with only a modest, temporary uptick in HZ that later falls below baseline as vaccinated cohorts age. Real-world evidence from the United States and European regions adopting two-dose schedules corroborates strong public health impact with significant cuts in primary care visits, hospitalizations, and outbreaks, particularly in school settings. Clinicians, schools, and parents should prepare for updated vaccination schedules, catch-up pathways, documentation requirements, and pragmatic infection control as the programme rolls out. This brief synthesizes the clinical background of varicella-zoster virus (VZV), outlines diagnostic and management considerations, summarizes the evidence base for one- and two-dose strategies, and highlights surveillance priorities and operational implications for the NHS, schools, and families. It integrates UK-focused modeling, comparative international experience, and up-to-date surveillance and clinical trial signals.

The UK’s confidential discounting of tirzepatide (marketed as Mounjaro for type 2 diabetes and as Zepbound for obesity in some jurisdictions) marks a pivotal moment for metabolic therapeutics. Incretin-based agents—particularly dual GIP/GLP‑1 receptor agonists—have demonstrated substantial and durable weight loss along with metabolic disease modification in large randomized trials. The clinical promise now intersects with health‑system realities: affordability, capacity to scale, and equitable access. For the NHS, price concessions via patient access schemes (PAS) and other commercial arrangements are a well‑established lever to align cost with value. Because obesity imposes rising burdens in cardiometabolic conditions, liver disease, sleep‑disordered breathing, and musculoskeletal morbidity, an effective therapy with long‑term benefits could shift population risk trajectories—if sustained access is feasible. Globally, a UK rebate can reverberate across pricing references, competitor strategies (e.g., GLP‑1 monotherapy), and supply planning, potentially accelerating adoption while intensifying scrutiny of outcomes and budget impact. Concurrent clinical developments—including completed Phase 3 trials in obstructive sleep apnoea (OSA) and ongoing studies on lean‑mass preservation during pharmacologic weight loss—underscore how broader health gains may further strengthen the value case.

Diffuse midline glioma (DMG), including diffuse intrinsic pontine glioma (DIPG), is among the most devastating pediatric brain tumors. Most cases harbor the hallmark histone H3 K27-alteration (commonly H3K27M), which rewires epigenetic programs and drives aggressive, infiltrative growth in the brainstem and other midline structures. Historically, focal radiation yields temporary neurologic improvement but nearly universal relapse. Durable disease control with systemic therapy has remained elusive. ONC201 (dordaviprone), the first-in-class imipridone and a pharmacologic activator of the mitochondrial protease ClpP that triggers the integrated stress response, has been extensively explored preclinically and clinically in DMG. As of August 2025, the U.S. FDA has approved dordaviprone (brand name MODEYSO) for adults and pediatric patients aged 1 year and older with H3 K27M-mutant DMG and progressive disease, with Jazz Pharmaceuticals as the NDA holder (NDA 219876), based on safety and efficacy data in this molecularly defined population. Compassionate-use series and translational monitoring studies suggest that a subset of patients experience clinical or radiographic stabilization, often accompanied by favorable biomarker dynamics, though broad, durable remissions remain uncommon in monotherapy settings. This review synthesizes mechanistic and clinical evidence to answer a critical question from families and clinicians: do ONC201 or related ClpP-activating agents materially help children with DMG—or do they mainly add adverse effects? We integrate regulatory developments, observational and translational data, and the current clinical trial landscape to provide a balanced, evidence-based appraisal.

Diffuse intrinsic pontine glioma (DIPG) is a highly aggressive pediatric brainstem glioma that classically arises in the pons and is characterized by diffuse infiltration, lack of surgical resectability, and historically poor outcomes. Over the last decade, molecular profiling has reframed DIPG within the broader category of diffuse midline gliomas (DMG), notably those harboring histone H3 lysine 27 to methionine mutations (H3K27M). This oncohistone change defines a biologically distinct subset strongly associated with adverse prognosis and unique epigenetic dysregulation. Clinically, the disease presents with rapidly progressive cranial neuropathies, long tract signs, and cerebellar dysfunction. Conventional focal radiotherapy remains the mainstay of initial disease control, while multimodal strategies—including re-irradiation at progression, locoregional delivery, and experimental immunotherapies—are being actively evaluated. In 2025, early-phase studies report feasibility and immune activation with oncolytic viruses, GD2-directed CAR T cells, and convection-enhanced radioimmunotherapy, reflecting a maturing translational pipeline. Importantly, in August 2025 the FDA approved oral dordaviprone (MODEYSO) for H3 K27M–mutant diffuse midline glioma with progressive disease in patients 1 year of age and older, marking a significant regulatory milestone that is reshaping trial design and clinical pathways in this population. This review synthesizes evidence across diagnostic pathology, clinical trials, and emerging therapeutics. We emphasize validated biomarkers such as H3K27M immunohistochemistry (IHC), evolving locoregional strategies (e.g., convection-enhanced delivery), and immuno-oncology approaches (oncolytic adenoviruses expressing IL-12 and GD2-directed CAR T cells). We also summarize the active clinical trials landscape using registry data to guide clinicians in current options and near-term developments.

Dental caries, commonly known as tooth decay, remains one of the most prevalent chronic diseases worldwide, affecting individuals across all age groups. This condition poses significant challenges to dental practitioners and public health officials alike, as it not only impacts oral health but also overall well-being. Recent oral health surveillance data highlights the persistent burden of dental caries, with approximately 45% of children and 90% of adults having experienced this condition. These statistics underscore the need for effective prevention and treatment strategies within dental practice. This article explores the global landscape of dental caries prevalence, drawing on current research findings and WHO oral health initiatives aimed at reducing disparities and improving oral health outcomes. The integration of recent data from the CDC and WHO provides a comprehensive view of the current state of dental caries, emphasizing the importance of targeted interventions and evidence-based practices in addressing this pervasive issue.
