Fifteen-minute consultation: Empowering children, young people and families through shared decision-making: a practical guide.

Shared decision-making (SDM) is a collaborative approach to healthcare decision-making that involves patients and healthcare professionals working together to make decisions that are informed by the best available medical evidence, as well as the patient's values, preferences and goals. The importance of SDM and the intricate interplay among parents, children and young people (CYP), and healthcare professionals are increasingly acknowledged as the crucial aspects of delivering high-quality paediatric care. While there is a substantial evidence base for SDM improving knowledge and reducing decisional conflict, the evidence for long-term measures such as improved health outcomes is limited and mainly inconclusive. To support healthcare teams in implementing SDM, the authors offer a practical guide to enhance decision-making processes and empower CYP and their families.

Left Upper Lobe Multi-Segmentectomy Versus Lobectomy for Early-Stage Lung Cancer: A Meta-Analysis.

INTRODUCTION: The left upper lobe (LUL) has unique hilar anatomy, and LUL multi-segmentectomy (apical trisegmentectomy and lingulectomy) may result in different outcomes than both single anatomical segmentectomy and left upper lobectomy in the management of early-stage primary lung cancer; however no meta-analyses have been performed. The aim of this meta-analysis is to determine if LUL multi-segmentectomy is non-inferior to left upper lobectomy for long-term survival outcomes, or superior for in-hospital outcomes. METHODS: Electronic databases searches were performed on PubMed, Embase, and the Cochrane Library to identify studies comparing outcomes in LUL multi-segmentectomy vs left upper lobectomy in early-stage lung cancer (clinical stage T2 N0 or less). Long-term postoperative overall and disease-free survival were assessed via reconstruction of Kaplan-Meier survival curves. In-hospital complications and length of stay, as well as long term recurrence were analysed via random effects models. RESULTS: Five relevant studies were identified, including 1,196 patients. Overall survival did not differ at 5 years (multi-segmentectomy 92.6% vs lobectomy 89.3%, P=0.188), but patients undergoing LUL multi-segmentectomy had better disease-free survival at 5 years (93.1% vs 88.4%, P=0.041). Patients undergoing LUL multi-segmentectomy had a shorter mean length of hospital stay (mean difference -0.26 days, 95% CI; -0.39 to 0.14, P<0.01, I2=0.00%). There was no difference in combined in-hospital complications (P=0.14), local recurrence (P=0.35), distant recurrence (P=0.23), or overall recurrence (P=0.39). CONCLUSION: LUL multi-segmentectomy is associated with reduced hospital length of stay, but no difference in long-term overall survival compared with left upper lobectomy in the management of early-stage primary lung cancer.

Preoperative Intra-Aortic Balloon Pumps in Cardiac Surgery: A Propensity Score Analysis.

INTRODUCTION: The role of intra-aortic balloon pumps (IABP) in high-risk patients undergoing coronary artery bypass graft (CABG) surgery remains controversial. We report the 5-year experience from a new Australian centre. METHODS: We retrospectively analysed 690 patients undergoing urgent isolated CABG surgery at a Western Australian tertiary centre from February 2015 to May 2020. De-identified data was obtained from the Australia & New Zealand Society of Cardiothoracic Surgeons database. Patients were stratified according to preoperative IABP use. A propensity score was created for the probability of IABP use and a propensity adjusted analysis was performed using logistic regression. The primary outcome was 30-day mortality. Secondary outcomes were postoperative inhospital outcomes. RESULTS: Preoperative IABP was used in 78 patients (11.3%). After propensity score adjustment, in a subgroup of patients with reduced ejection fraction or left main disease, 30-day mortality (7.0% vs 2.0%, OR 6.03, 95% CI 1.89-19.28, p=0.002) was significantly higher in the IABP group. Red blood cell transfusions (19.7% vs 12.6%, OR 1.86, 95% CI 1.02-3.35, p=0.039), prolonged inotrope use (78.9% vs 50.9%, OR 6.11, 95% CI 2.77-13.48, p<0.001), prolonged invasive ventilation (28.2% vs 3.4%, OR 20.2, 95% CI 8.24-49.74, p<0.001), mesenteric ischaemia (2.8% vs 0%, OR 4.52, 95% CI 1.15-17.77, p=0.031) and multisystem organ failure (1.3% vs 0.7%, OR 25.68, 95% CI 2.55-258.34, p=0.006) were significantly higher in the IABP group. CONCLUSION: In patients undergoing isolated CABG surgery, preoperative IABP use was associated with increased 30-day mortality and adverse outcomes. Large randomised controlled trials are required to confirm our findings.

A proteomics-based approach identifies secreted protein acidic and rich in cysteine as a prognostic biomarker in malignant pleural mesothelioma.

BACKGROUND: We aimed to identify prognostic blood biomarkers using proteomics-based approaches in malignant pleural mesothelioma (MPM). METHODS: Plasma samples from 12 MPM patients were used for exploratory mass spectrometry and ELISA analyses. The significance of secreted protein acidic and rich in cysteine (SPARC) was examined in sera from a Dutch series (n=97). To determine the source of the circulating SPARC, we investigated SPARC expression in MPM tumours and healthy controls, as well as the expression and secretion from cell lines and xenografts. RESULTS: Secreted protein acidic and rich in cysteine was identified as a putative prognostic marker in plasma. Validation in the Dutch series showed that the median survival was higher in patients with low SPARC compared with those with high SPARC (19.0 vs 8.8 months; P=0.01). In multivariate analyses, serum SPARC remained as an independent predictor (HR 1.55; P=0.05). In MPM tumour samples, SPARC was present in the tumour cells and stromal fibroblasts. Cellular SPARC expression was higher in 5 out of 7 cell lines compared with two immortalized mesothelial lines. Neither cell lines nor xenograft tumours secreted detectable SPARC. CONCLUSIONS: Low circulating SPARC was associated with favourable prognosis. Secreted protein acidic and rich in cysteine was present in both tumour cells and stromal fibroblasts; and our in vitro and in vivo experiments suggest that stromal fibroblasts are a potential source of circulating SPARC.

Point-of-care ultrasound as a diagnostic tool in respiratory assessment in awake paediatric patients: a comparative study.

BACKGROUND: Chest X-ray (CXR) has typically been the main investigation in children with suspected respiratory pathology. Recent advances in lung point-of-care ultrasound (POCUS) have shown the potential for it to be comparative, if not better, than CXR. The objective of this study was to compare CXR with lung POCUS in children with respiratory illness in a ward-based setting at a paediatric teaching hospital. METHODS: Any child <18 years of age presenting to Southampton Children's Hospital requiring a CXR for clinical reasons also had lung POCUS performed. CXR was reported by a consultant paediatric radiologist and lung POCUS was reviewed retrospectively by a blinded POCUS clinician, with only the clinical information provided on the CXR request. Comparisons were made between the CXR and lung POCUS findings. RESULTS: 100 paired lung POCUS and CXR were included in the study. 30% of lung POCUS were normal with 97% of these having a normal CXR. 70% of cases had POCUS abnormalities with 96% of POCUS cases identifying comparative lung pathology. Lung POCUS therefore had a sensitivity of 98.51% and a specificity of 87.9% with a diagnostic accuracy of 95% when compared with the CXR report. CONCLUSIONS: Lung POCUS has excellent diagnostic accuracy. The diagnosis of normal lung on POCUS when performed by a trained practitioner can reliably reduce the need for a CXR, thus reducing CXR use and radiation exposure in children. An abnormal lung POCUS could then either give the diagnosis or lead to a CXR with the expectation of clinically relevant findings.

Dual inflow, total-arterial, anaortic, off-pump coronary artery bypass grafting: how to do it.

Coronary surgery performed on an arrested heart, using one internal mammary artery and a saphenous vein carries two main potential drawbacks: the known failure rate of vein grafts and the relatively high rate of neurologic injury. To address these concerns, we describe a technique that achieves complete revascularization without manipulating the ascending aorta (anaortic, off-pump) and utilizing total arterial grafts. All patients undergo thorough preoperative investigation, including bilateral carotid, vertebral and subclavian artery Duplex ultrasounds. A pulmonary artery catheter, transoesophageal echocardiography, and point-of-care coagulation testing are used in each case. The left and right internal mammary arteries and non-dominant radial artery are harvested using a fully skeletonised technique. Wide bilateral extrapleural retrothymic tunnels are developed and the pericardium is opened widely to facilitate cardiac positioning. A tandem graft is constructed with the right internal mammary artery (RIMA) in situ and radial artery using an end-to-end anastomosis. This graft is brought into the pericardium and through the transverse sinus in order to graft the lateral and inferior walls with multiple sequential distal anastomoses. The left internal mammary artery (LIMA) in situ is used to graft the anterior wall. Four main cardiac positions (high and low lateral walls, inferior and anterior walls) are obtained using a combination of off-pump stabilizer positioning, alternate tension on pericardial 'heart-strings', table tilting and folded wet sponges. All distal anastomoses are performed using silastic intracoronary shunts and an off-pump myocardial stabilizer. All grafts are checked using transit-flow time measurements. Milrinone is continued overnight and dual antiplatelet therapy is continued for 3 months postoperatively.

Mechanical Versus Bioprosthetic Aortic Valve Replacement in Middle-Aged Adults: A Systematic Review and Meta-Analysis.

The choice of a bioprosthetic valve (BV) or mechanical valve (MV) in middle-aged adults undergoing aortic valve replacement is a complex decision that must account for numerous prosthesis and patient factors. A systematic review and meta-analysis was performed to compare long-term survival, major adverse prosthesis-related events, anticoagulant-related events, major bleeding, reoperation, and structural valve degeneration in middle-aged patients receiving a BV or MV. A comprehensive search from six electronic databases was performed from their inception to February 2016. Results from patients aged less than 70 years undergoing aortic valve replacement with a BV or MV were included. There were 12 studies involving 8,661 patients. Baseline characteristics were similar. There was no significant difference in long-term survival among patients aged 50 to 70 or 60 to 70 years. Compared with MVs, BVs had significantly fewer long-term anticoagulant-related events (hazard ratio [HR] 0.54, p = 0.006) and bleeding (HR 0.48, p < 0.00001) but significantly greater major adverse prosthesis-related events (HR 1.82, p = 0.02), including reoperation (HR 2.19, p < 0.00001). The present meta-analysis found no significant difference in survival between BVs and MVs in patients aged 50 to 70 or 60 to 70 years. Compared with MVs, BVs have reduced risk of major bleeding and anticoagulant-related events but increased risk of structural valve degeneration and reoperation. However, the mortality consequences of reoperation appear lower than that of major bleeding, and recent advances may further lower the reoperation rate for BV. Therefore, this review supports the current trend of using BVs in patients more than 60 years of age.
