Abstract:

Critical closing pressure (CCP) and the vascular waterfall have long been used to explain perfusion failure in shock, yet their physiological meaning has been inconsistently interpreted. CCP is frequently treated as a continuous downstream pressure and inserted into formulas such as mean arterial pressure (MAP) – CCP, implying that a collapse threshold behaves like an opposing pressure even when vessels remain open. Drawing on classical vascular mechanics, whole-bed flow studies, microvascular models, and contemporary clinical physiology, we show that this interpretation is incorrect. Tone-dependent arteriolar collapse does not behave as a Starling resistor: CCP is a threshold at which smooth-muscle tension exceeds intraluminal pressure and vessels close, not a pressure governing flow in patent vessels. Perfusion becomes heterogeneous because different vascular beds reach their collapse thresholds at different pressures (via excessive tone, extrinsic compression, or profound hypotension), disconnecting macro-haemodynamics from microcirculatory flow. This explains why systemic variables such as MAP and systemic vascular resistance (SVR) may appear adequate even while tissues are under-perfused, a phenomenon now termed haemodynamic incoherence. Reframing CCP as a binary collapse threshold resolves longstanding contradictions in the literature, clarifies why MAP-centred targets often fail, and unifies the behaviour of shock states within a four-interface model of circulatory coupling. Therapeutically, the aim is not to "restore a waterfall" but to reopen closed vascular territories by lowering excessive tone, relieving external pressure, or raising truly low arterial inflow. This mechanistic reinterpretation provides a more coherent, physiologically grounded approach to personalised perfusion management in critical illness.

Abstract:

BACKGROUND: Day case elective surgery is becoming increasingly common across a range of procedures. The aim of this study was to investigate the safety of day case thyroid lobectomy, a procedure with low uptake in the UK.

METHODS: This study analysed the Hospital Episode Statistics administrative data set for all first-time elective thyroid lobectomies performed on adults in England from 1 April 2017 to 31 March 2024. The primary outcome was 30-day emergency readmission and secondary outcomes were 30-day emergency readmission for complications and specifically for haemorrhage. The primary exposure variable was whether patients were day case patients or inpatients. Models were adjusted for the demographic and frailty characteristics of the patients.

RESULTS: Over the 7-year interval, 41 518 elective thyroid lobectomies were performed by 127 different hospital trusts. The day case rate was 9.9% (4125 patients) across all hospital trusts. Rates in the 118 hospital trusts conducting >20 procedures during the 7 years varied from 0% to 74.6%. Day case surgery was associated with a lower 30-day emergency readmission rate (OR 0.73 (95% c.i. 0.56 to 0.96); P < 0.021), with no evidence of association with poorer outcomes. There was no evidence that trusts with day case rates >30% had poorer outcomes than trusts with day case rates <1%.

CONCLUSION: In low-risk patients, day case thyroid lobectomy is safe.

Abstract:

This case report presents the clinical scenario of a 35-year-old male patient who experienced chest pain due to a combination of pulmonary embolism (PE) and myocardial infarction with non-obstructive coronary arteries (MINOCA), concurrently while undergoing treatment with avatrombopag for immune thrombocytopenia (ITP). His investigations included a CT pulmonary angiogram that confirmed a PE, a coronary angiography which was normal, a cardiac MRI which showed evidence of subendocardial infarct, and a CT coronary angiogram, which was normal. His unique presentation with these findings prompted further investigations, which revealed an undiagnosed antiphospholipid syndrome (APS) alongside a patent foramen ovale (PFO). Hence, the paradoxical thrombotic incidents were precipitated by this unique diagnosis. After establishing the diagnosis, our patient was commenced on warfarin, and his treatment protocol for ITP was changed to a different drug. He remains under haematology follow-up.

Abstract:

INTRODUCTION AND HYPOTHESIS: Obstructed defecation syndrome (ODS) is a defecatory abnormality with a sensation of incomplete evacuation, the need to strain at stool, the need for digitation in the vagina, the anus, or the perineum. Anterior rectocele and rectal intussusception are the frequent pathologies behind ODS. The review focuses on the assessment and treatment of obstructed defecation in women with rectocele, recto-enterocele and rectal intussusception in the remit of a urogynecologist.

METHODS: A working subcommittee from the International Urogynecology Association (IUGA) Research and Development (R&D) Committee was formed with colorectal surgeons from the American Society of Colon & Rectal Surgeons (ASCRS). An initial document was drafted based on a literature review. The review focused on the treatment options of women with presenting with obstructed defecation and posterior compartment prolapse either on clinical examination or on imaging. After evaluation by the entire IUGA R&D Committee revisions were made. The quality of the evidence was graded and used to form consensus recommendations.

RESULTS: Ultrasound and dynamic MRI are helpful imaging modalities in triaging patients. A defecating proctogram to evaluate the size of rectal intussusception and enterocele is the standard investigation. Conservative therapies are effective first-line management options. The transvaginal native tissue rectocele repair is a safe and effective first-line surgical treatment in women with obstructed defecation.

CONCLUSIONS: When evaluating patients with obstructive defecation, it is important to address anatomy as well as function. In the absence of a clinically significant rectocele or enterocele during vaginal examination, in women with obstructed defecation, referral to a gastroenterologist or colorectal surgeon for further evaluation and management is recommended.

Abstract:

PURPOSE: Management of chronic Achilles tendon ruptures (CATR) varies according to patient and injury characteristics, but clear guidelines regarding the evaluation and treatment options are still lacking. This study aims to identify tendencies regarding the evaluation and management of CATR among foot and ankle orthopaedic surgeons. The research question is if there is any tendency regarding evaluation, preoperative planning, choice of surgical approach and technique for management of CATR.

METHODS: A web-based questionnaire was distributed through 56 national and international foot and ankle orthopaedic societies. Replies were pooled and analysed. A 'main tendency' was considered when 75% of the participants chose the same treatment method, a 'tendency' for 50%-75%, and 'no tendency' when less than 50% choose the same method.

RESULTS: A total of 667 orthopaedic surgeons from 60 countries participated. Most respondents were experienced, specialised foot and ankle surgeons; however, 68% managed fewer than five CATR annually. MRI was the predominant imaging modality selected for surgical planning (88%). Gap size (80%) is the principal determinant of technique selection, followed by time from injury (61%) and then patient age (57%). Open repair was the most common technique (66%). End-to-end repair for defects <2 cm was the only treatment tendency (68%). Rehabilitation strategies were heterogeneous, though plaster immobilisation in equinus (55%), walker boot use for partial weight-bearing (90%), and physiotherapy initiation at 4-6 weeks following surgery were common tendencies. Compared with acute ruptures, functional outcomes were perceived as slightly worse in CATR (54%).

CONCLUSION: This study confirms significant variation in CATR management internationally. While end-to-end repair is a consistent choice for gaps smaller than 2 cm, the variability observed in responses reflects the lack of evidence and clear treatment algorithms.

Abstract:

BACKGROUND: Narrowband UVB (NBUVB) is a second-line treatment for chronic moderate-to-severe atopic eczema unresponsive to adequate topical therapy, and is known to induce good short-term improvement of eczema severity. However, it is unclear how adult patients fare with their eczema severity long after completion of a course of NBUVB.

OBJECTIVES: We aimed to investigate the severity of atopic eczema in adults, 1 year following completion of NBUVB, using validated clinical activity measures.

METHODS: We undertook a multi-centre prospective observational study of adults with moderate-to-severe atopic eczema who were prescribed NBUVB as part of their standard clinical care. Assessments were made at baseline prior to starting NBUVB, at the end of NBUVB and at 4, 8 and 12 months after completion of NBUVB.

RESULTS: Eighty participants with moderate-to-severe atopic eczema (mean SCORAD 39.2, POEM 18.5, IGA 3.2) underwent NBUVB therapy. Significant reductions were observed post-treatment: SCORAD decreased to 17.8, POEM to 8.2, and IGA to 1.7 (p<0.001 achieved for all time points). These therapeutic effects were sustained at 4, 8, and 12 months post-treatment (n=27 at 12 months). Loss of follow-up was attributed to non-attendance exacerbated by the COVID-19 pandemic and patient relocation. Mild adverse events (n=5), including erythema and eczema flares, were reported, with no serious events.

CONCLUSIONS: These findings indicate that NBUVB may provide a long-lasting effect for patients who complete a course, helping to diminish their eczema severity to a more manageable level.

Abstract:

INTRODUCTION: Patients awaiting elective procedures often have conditions that carry a risk of medical emergencies. This study quantifies the extent and variation of emergency hospital admissions during the waiting period across selected specialties and procedures.

METHODS: Data from the NHS England Waiting List Minimum Dataset linked to the Secondary Uses Service hospital admissions data set from 1 January 2022 to 31 December 2023 was analysed. Emergency admissions occurring while patients awaited treatment were identified and categorized from 'very likely' related to the index condition or its recognized co-morbid risks-and potentially avoidable through definitive treatment-through to 'unrelated'.

RESULTS: In 2023 some 2 093 789 waits (both incomplete and complete) were recorded across 41 selected procedures spanning 11 specialties. Over a combined waiting time of 33 832 790 days, 69 322 emergency admissions occurred, accounting for 535 806 bed days. The highest emergency admission rates per 52 weeks waiting were observed for urinary stent procedures (0.71), endoscopic retrograde cholangiopancreatography (0.63), and urinary catheter care (0.55). Nine procedures had more emergency bed days during the wait than elective bed days post-treatment, with the highest emergency/elective bed day ratios for ureteric stones (4.59), colonoscopy (2.80), and ablation/cardioversion (2.05).

CONCLUSION: A substantial number of patients on elective waiting lists are being admitted as emergencies during their wait, placing a burden on emergency care that would be avoided through more timely treatment. The variation in risk between specialties and pathways requires further prioritization strategies that mitigate patients' risk of associated harm, acting both within and across waiting lists, specialties, and organizations.

Abstract:

Cardiotocography (CTG) is a common investigative modality in obstetrics to evaluate the fetal condition. Advancements in digital technology has enabled the innovation of CTG monitoring for usage in the home setting. This review aims to comprehensively examine the current evidence on the effectiveness and applicability of home antenatal CTG monitoring. MEDLINE, EMBASE, Cochrane, Web of Science, and PubMed databases were searched from inception to June 2025. Primary studies examining home antenatal CTG were included. For randomised controlled trials (RCTs), the joint primary outcomes were perinatal mortality and emergency caesarean section. For observational studies, the feasibility, diagnostic accuracy, qualitative and economic burden of home CTG were evaluated. RCTs were eligible for meta-analysis using risk ratio or mean difference, with 95% confidence intervals. Included observational studies were narratively described due to significant methodological heterogeneity. 39 studies (28 observational, seven RCTs and four qualitative studies), comprising of 7240 participants were included. Home antenatal CTG monitoring was non-inferior to conventional care across all meta-analysed maternal, perinatal and healthcare usage outcomes. GRADE assessments were low/very low quality of evidence. Home CTG monitoring was feasible in several settings and remote interpretation was graded as moderate to excellent. Transmission failures were frequently low but commonly occurred due to infrastructure and/or equipment errors. Remote CTG monitoring demonstrated comparative capabilities to conventional CTG with respect to coincidence and beat-to-beat variability. Overall acceptability ratings were high for patient and providers. Often implementation costs were high but accrued back by non-fixed savings when compared against routine care. High-quality studies were underrepresented, particularly when assessing service-led and safety outcomes. Home antenatal CTG monitoring demonstrates noninferiority to conventional care across several outcomes, representing a promising avenue for antenatal management However, current evidence is of low quality and additional high-quality evidence with sufficient methodological detail and standardised outcome assessment is required prior to making definitive recommendations.
