MRCPCH Weekly — 11 September 2026
A briefing for MRCPCH candidates · covering 4–11 September 2026
This week: AKP 2026.3 sits next Wednesday, the consultation on the redesigned Clinical exam is due to open this month, and new work on chemotherapy's genomic legacy, the infant skin microbiome and autism outcomes leads the journals.
General
Your autumn exam diary, at a glance. AKP 2026.3 sits on Wednesday 16 September and FOP/TAS 2026.3 follows on 14 October. Applications for AKP 2027.1 (exam 20 January) open on 2 November and close 6 November online — 9 November for test centres — and the full 2027 theory calendar is now listed. (RCPCH theory exam dates)
Top 5 in paediatrics & neonatal medicine this week
Wales risks its "unhealthiest generation in decades". RCPCH Wales' new analysis reports the highest early-childhood obesity ever recorded (27.3% of 4–5-year-olds), tooth decay in 27% of 5–6-year-olds, ~135,000 children with diagnosable mental-health conditions and a 378% September asthma-admission spike. A companion report warns of a "shocking decline" in Northern Ireland. (RCPCH, 7–9 Sep 2026)
Childhood chemotherapy leaves lasting DNA damage in healthy cells. Using ultrasensitive NanoSeq sequencing, a Science study of childhood cancer survivors found platinum-based chemotherapy left healthy tissues with mutation burdens equivalent to decades of ageing, plus a previously unknown liver-specific damage signature — sharpening understanding of second-malignancy risk in long-term follow-up. (Science, 10 Sep 2026)
Infant skin microbiome may predict eczema and food allergy. Shotgun metagenomics of 1,000+ swabs from 429 infants found microbiome shifts at 2–3 months preceding later eczema and food allergy, with distinct profiles in FLG-mutation carriers — pointing to early biomarkers and prevention windows, and firmly on-syllabus for atopy and the skin barrier. (Allergy, 9 Sep 2026)
Autism linked to a 14-year life-expectancy deficit. A JAMA Network Open analysis of over two million autistic US Medicaid beneficiaries found life expectancy of 64.9 years — 13.8 years below the general population — with excess deaths from pneumonia, influenza, accidents and drowning, underscoring preventable-mortality themes in neurodisability and safeguarding teaching. (JAMA Network Open, 10 Sep 2026)
"Smart jumpsuit" builds growth charts for infant motor development. A Science Translational Medicine study used a sensor-laden wearable and deep learning across 1,227 hours of at-home play in 92 infants to chart gross motor development continuously, flagging 121 of 220 metrics as abnormal in neurodevelopmental follow-up cases — a glimpse of developmental surveillance beyond milestone checklists. (Sci Transl Med, 8 Sep 2026)
Clinical Exam
Consultation watch: redesign feedback window due this month. RCPCH's assessment-review timeline still lists a September 2026 consultation on the redesigned Clinical exam — a proposed 12-station OSCE piloted in December 2025 and June 2026 — with Council approval and GMC submission targeted for September–October. As of 11 September no consultation link has appeared; current candidates sit the existing format. (RCPCH assessment review)
Evergreen tip: Drill examination technique against the official guidance. The face-to-face guidance hub collects candidate guidance, station structure and RCPCH's own clinical examination technique document — practising each system examination to that published sequence, out loud and under time, remains the most reliable way to score across stations.
AKP
Five days to go: AKP 2026.3 sits Wednesday 16 September. Final-week priorities: confirm your test-centre or online-invigilation details and ID against your admission email, rehearse the on-screen format, and taper rather than cram. Results reach online accounts six to seven weeks after the sitting, with detailed feedback emailed about a week later. (RCPCH theory exam dates)
Key dates: 16 Sep 2026 — AKP 2026.3 exam day · 2–6 Nov 2026 — AKP 2027.1 applications (to 9 Nov for test centres); exam 20 Jan 2027.
TAS
No new TAS-specific announcements this week.
Five weeks out — and 2027 dates are now published. TAS 2026.3 sits on 14 October; applications closed in August, so registered candidates should be deep into physiology, pharmacology, genetics and evidence-based medicine. Planning further ahead, FOP/TAS sittings for 2027 are confirmed for 17 February, 23 June and 13 October. (RCPCH theory exam dates)
FOP
No new FOP-specific announcements this week.
Evergreen tip: FOP shares the 14 October sitting — revise to the syllabus domains. RCPCH's theory-exam guidance covers format, timing and test-centre rules for the single-best-answer papers. FOP samples broad foundation-level paediatrics — child health, development and common acute presentations — so structure revision around the published syllabus domains and rehearse timing with full-length practice papers.
