3±27.6 days. Twenty-four adverse events occurred in 19 patients (32%); most frequent adverse events were abdominal pain or discomfort (n=9) and constipation (n=3).

Ferric maltol increases haemoglobin and iron indices and is generally well tolerated in patients with IBD and IDA treated in clinical practice. These real-world data support findings from randomised controlled trials.

To compare the 1973 WHO and the 2004/2016 WHO grading systems in patients with urothelial carcinoma of urinary bladder (UCUB), since no consensus has been made which classification should supersede the other and since both are recommended in clinical practice.

Newly diagnosed patients with Ta UCUB treated with transurethral resection of bladder tumour were abstracted from the Surveillance, Epidemiology and End Results database (2010-2016). Kaplan-Meier plots and multivariable Cox regression models (CRMs) tested cancer-specific mortality (CSM), according to 1973 WHO (G1 vs G2 vs G3) and to 2004/2016 WHO (low-grade vs high-grade) grading systems.

Of 35 986 patients, according to 1973 WHO grading system, 8165 (22.7%) were G1, 17 136 (47.6%) were G2 and 10 685 (29.7%) were G3. According to 2004/2016 WHO grading system, 24 961 (69.4%) were low-grade versus 11 025 (30.6%) high-grade. In multivariable CRMs, G3 (HR 2.05, p<0.001), relative to G1, and high-grade(HR 2.13, p<0.001), relative to low-grade, predicted higher CSM. Conversely, G2 (p=0.8) was not an independent predictor. The multivariable models without consideration of either grading system were 74% accurate in predicting 5-year CSM. After addition of 1973 WHO or 2004/2016 WHO grade, the accuracy increased to 76% and 77%, respectively.

From a statistical standpoint, it appears that the 2004/2016 WHO grading system holds a small, although measurable advantage over the 1973 WHO grading system. Other considerations, such as intraobserver and interobserver variability may represent an additional matric to consider in deciding which grading system is better.

The objective of this cohort study was to analyse long-term relative survival in patients with bicuspid aortic valve (BAV) who underwent aortic valve surgery.

We studied 865 patients with BAVs who participated in three prospective cohort studies of elective, open-heart, aortic valve surgery at the Karolinska University Hospital, Stockholm, Sweden, between 2007 and 2020. The expected survival for the age, sex and calendar year-matched general Swedish population was obtained from the Human Mortality Database. The Ederer II method was used to calculate relative survival, which was used as an estimate of cause-specific survival.

No differences were found in the observed versus expected survival at 1, 5, 10 or 12 years 99%, 94%, 83% and 76% vs 99%, 93%, 84% and 80%, respectively. The relative survival at 1, 5, 10 and 12 years was 100% (95% CI 99% to 100%), 101% (95% CI 99% to 103%), 99% (95% CI 95% to 103%) and 95% (95% CI 87% to 102%), respectively. The relative survival at the end of follow-up tended to be lower for women than men (86% vs 95%). The mean follow-up was 6.3 years (maximum 13.3 years).

The survival of patients with BAV following aortic valve surgery was excellent and similar to that of the general population. Our results suggest that the timing of surgery according to current guidelines is correct and provide robust long-term survival rates, as well as important information about the natural history of BAV in patients following aortic valve surgery.

Similarities and differences between these guidelines should be viewed in the context of different objectives, responsibilities and roles of guideline developers. This review describes the NICE clinical guidelines development principles and processes with the aim to provide the reader an informed perspective on the recommendations made. NICE clinical guidelines are developed by an appointed independent advisory committee comprising healthcare professionals as well as lay members, supported by a professional team comprising project managers, information specialists, systematic reviewers and health economists. Furthermore, registered stakeholders comprising organisations that have an interest in the guideline topic, or represent people whose practice or care may be directly affected by the guideline, are consulted on the draft scope and draft guidelines. NICE selects a limited number of high impact questions to be answered by the review of evidence, rather than cover a certain topic exhaustively as the clinical guidelines developed by professional societies may do. NICE clinical guidelines recommendations reflect both the clinical effectiveness and the cost-effectiveness of interventions.
To evaluate the outcomes of immunosuppressive therapy (IST) discontinuation in patients with neuromyelitis optica spectrum disorder (NMOSD) after a sustained remission period.

We retrospectively reviewed the medical records of 17 patients with antiaquaporin-4 antibody-positive NMOSD who discontinued IST after a relapse-free period of ≥3 years.

IST was discontinued at a median age of 40 years (interquartile range [IQR], 32-51) after a median relapse-free period of 62 months (IQR, 52-73). Among the 17 enrolled patients, 14 (82%) relapsed at a median interval of 6 months (IQR, 4-34) after IST discontinuation, 3 (18%) of whom experienced severe attacks; notably, all 3 of these patients had a history of severe attack before IST. These 3 patients received steroids, followed by plasma exchange for acute treatment, but 2 exhibited poor recovery and significant disability worsening at 6 months after relapse.

IST discontinuation may increase the risk of relapse in seropositive patients with NMOSD even after 5 years of remission.
