Background and objective Continuous positive airway pressure (CPAP) is the most common treatment for obstructive sleep apnoea (OSA), but many patients fail long‐term therapy. Bilevel positive airway pressure (BPAP) is a potential alternative. We hypothesized that BPAP could improve treatment adherence and outcomes in patients who cannot tolerate CPAP. Methods Patients with OSA who failed CPAP (usage < 4 h/day) and were referred to a tertiary sleep centre between 2014 and 2017 for BPAP were included. Age, gender, body mass index (BMI), co‐morbidities, CPAP use and reasons for failure, Epworth Sleepiness Scale (ESS), sleep study data, spirometry data and average maximum nightly compliance were recorded. Results A total of 52 patients with OSA requiring CPAP > 15 cm H2O (71% male, age: 58 (15) years, BMI: 42.6 (10.1) kg/m2, apnoea–hypopnoea index (AHI): 51.1 (30.4)/h) were studied; 62% had respiratory co‐morbidities affecting nocturnal breathing including obesity hypoventilation syndrome and COPD; 25% had neuromuscular conditions; and 17% had cardiovascular disease. CPAP was used for 199 (106–477) days prior to referral for BPAP. Reasons for CPAP failure were intolerant pressures (23%), uncontrolled symptoms (23%), mask problems (21%), adverse effects (13%), claustrophobia (8%), co‐morbidities (8%) and other issues (4%). Lower expiratory positive airway pressures were needed with BPAP compared to CPAP (10 (8–12) vs 16.8 (15.7–19.2) cm H2O, P = 0.001); patients achieved better adherence to BPAP (7.0 (4.0–8.5) vs 2.5 (1.6–6.7) h/night, P = 0.028) and better symptom control (ESS: 4.0 (1.0–7.0) vs 10.0 (6.0–17.0) points, P = 0.039). Conclusion In patients with moderate–severe OSA who fail CPAP therapy due to low adherence, BPAP is well tolerated and achieves sufficient control of sleep‐disordered breathing and its symptoms.

HighlightsThere is no consensus on the optimal flexor tendon repair technique at each anatomical flexor zone.There is paucity of high quality evidence.Heterogenous study designs limit inter-study comparisons.Patient reported outcome measures are crucial but there is a perennial need for robust disease-specific tools to be utilised.

PurposeCardiac resynchronisation therapy (CRT) is an established treatment for symptomatic patients with heart failure, a prolonged QRS duration, and impaired left ventricular (LV) function; however, non-response rates remain high. Recently proposed computer-assisted interventional platforms for CRT provide new routes to improving outcomes. Interventional systems must process information in an accurate, fast and highly automated way that is easy for the interventional cardiologists to use. In this paper, an interventional CRT platform is validated against two offline diagnostic tools to demonstrate that accurate information processing is possible in the time critical interventional setting.MethodsThe study consisted of 3 healthy volunteers and 16 patients with heart failure and conventional criteria for CRT. Data analysis included the calculation of end-diastolic volume, end-systolic volume, stroke volume and ejection fraction; computation of global volume over the cardiac cycle as well as time to maximal contraction expressed as a percentage of the total cardiac cycle.ResultsThe results showed excellent correlation ( values of and Pearson correlation coefficient of ) with comparable offline diagnostic tools.ConclusionResults confirm that our interventional system has good accuracy in everyday clinical practice and can be of clinical utility in identification of CRT responders and LV function assessment.

Objectives Analyse clinical characteristics and treatment provided to an adult population diagnosed with intracranial ependymomas between 2009–2018. Methods Single centre retrospective cohort study. Variables reviewed: demographics, extent of resection, adjuvant oncological treatment and molecular genetics. Results 17 patients were included (6 females, 11 males). Average age at presentation was 51.3 yrs (range 19-74yrs). 4 supratentorial (2 intraventricular, 1 temporal lobe and 1 frontal lobe) and 13 infratentorial lesions were identified. In the supratentorial subgroup the following treatment was performed: GTR (1 patient), STR (1 patient) and Biopsy (2 patients); 2 patients underwent post-operative radiotherapy. 3 patients had a WHO grade 2 tumour (1 patient - insufficient tissue for grading). 3 recurrences were identified and 2 patients had re-debulking. 2 patients had postoperative hemiparesis, 1 patient died during treatment and 3 are currently being followed up. In the infratentorial subgroup the following treatment was performed: GTR (5 patients), STR (7 patients) and biopsy (1 patient). 3 patients underwent post-operative radiotherapy. 1 patient was WHO grade 1, 11 patients were WHO grade 2 and 1 patient was WHO grade 3. 2 patients had tumour recurrences of which 1 was re-operated. 7 patients develop new post-operative deficits after surgery; 1 patient died and the rest are currently being followed up. Conclusion Even though this case series supports the good prognosis in terms of overall survival in adults with intracranial ependymomas, they represent a challenge to manage given the morbidity of optimal surgical resection and their poor response to adjuvant treatment.
