The burden of constipation from the patient's perspective has been well described. The aim of this study was to evaluate the cost of managing constipation in patients taking opioids in a specialist palliative care inpatient unit. A retrospective review of the medical records of 58 patients (70 admissions) who died during a six-month period was undertaken to identify prescribing patterns for opioids and oral laxatives and tasks associated with managing constipation in these patients. A prospective time and motion study also was undertaken, whereby staff recorded the time and resources required to perform each task. These data were then applied to the actual frequency recorded in the retrospective review to calculate the direct cost of managing constipation in those 70 admissions during that six-month period. There was no discernable pattern in oral laxative prescribing. The mean cost of managing constipation was 29.81 pounds (48.74 USD) per admission, with staff time accounting for 85% of the cost. The most time-consuming activity was staff discussion about bowel management, which occurred at least once daily for doctors and twice for nurses and involved up to eight members of staff at a time. The cost of managing constipation is skewed in that it costs 30 pounds (49 USD) or less in 71% of admissions but exceeded 100 pounds (163 USD) in 5%. In the latter group, earlier and/or more effective intervention for constipation could lead to clinical and economic benefits.
The SPIRE study demonstrated activity of pazopanib in heavily pretreated aSTS patients in a compassionate use setting. No new safety concerns were noted. Reassuringly, the relative dose intensity of pazopanib was 92%.
A retrospective cohort analysis to explore 10-year mortality and prevalence of transfusion-dependent b-thalassaemia (TDT)-associated co-morbidities in patients with TDT was undertaken using Hospital Episode Statistics (HES) data from the National Health Service (NHS) in England. A 10-year forward-looking cohort analysis for the period 2009-2018 was completed using HES admitted patient care (APC), outpatient data, and linked HES/ Office of National Statistics mortality data for patients with b-thalassaemia (ICD-10 diagnosis code D56.1). TDT-associated co-morbidity rates were high in the 612 patients with TDT, with 76% having at least one co-morbidity, 54% suffering from two of more, and 37% three or more. The three most common TDT-associated co-morbidities, occurring in more than one third of patients were: endocrine disorders (excluding diabetes) 40%, osteoporosis 40%, and diabetes 34%. Cardiac disease was observed in 18% of patients overall, with atrial fibrillation and heart failure being the most common with a prevalence of 11% and 9%, respectively. The crude 10-year mortality rate in the TDT cohort was 6Á2% (38/612), significantly greater than the 1Á2% age/sex-adjusted mortality rate of the general population (P < 0Á001). These data support the notion that the unmet need in TDT remains significant, with high rates of co-morbidity and mortality.
Background:Lapatinib, a dual EGFR and HER2 inhibitor has shown disappointing results in clinical trials of metastatic oesophago-gastric adenocarcinomas (OGAs), and in vitro studies suggest that MET, IGFR, and HER3 confer resistance. This trial applied Lapatinib in the curative neoadjuvant setting and investigated the feasibility and utility of additional endoscopy and biopsy for assessment of resistance mechanisms ex vivo and in vivo.Methods:Patients with HER2 overexpressing OGA were treated for 10 days with Lapatinib monotherapy, and then in combination with three cycles of Oxaliplatin and Capecitabine before surgery. Endoscopic samples were taken for molecular analysis at: baseline including for ex vivo culture +/− Lapatinib to predict in vivo response, post-Lapatinib monotherapy and at surgery. Immunohistochemistry (IHC) and proteomic analysis was performed to assess cell kinetics and signalling activity.Results:The trial closed early (n=10) due to an anastomotic leak in two patients for which a causative effect of Lapatinib could not be excluded. The reduction in Phosphorylated-HER2 (P-HER2) and P-EGFR in the ex vivo-treated biopsy demonstrated good correlation with the in vivo response at day 10. Proteomic analysis pre and post-Lapatinib demonstrated target inhibition (P-ERBB2, P-EGFR, P-PI3K, P-AKT, and P-ERK) that persisted until surgery. There was also significant correlation between the activation of MET with the level of P-Erk (P=0.0005) and P-PI3K : T-PI3K (total PI3K) ratio (P=0.0037). There was no significant correlation between the activation status of IGFR and HER3 with downstream signalling molecules.Conclusions:Additional endoscopy and biopsy sampling for multiple biomarker endpoints was feasible and confirmed in vitro data that MET is likely to be a significant mechanism of Lapatinib resistance in vivo.
Objectives Transfusion-dependent β-thalassemia (TDT) is a genetic disease that affects production of red blood cells. Conventional treatment involves regular red blood cell transfusions and iron chelation, which has a substantial impact on quality of life. While potentially curative, allogeneic hematopoietic stem cell transplantation (allo-HSCT) is associated with risk of complications, including graft-versus-host disease (GvHD). Gene addition therapy, a novel treatment approach, involves autologous transplantation of the patient's own genetically modified hematopoietic stem cells. The purpose of this study was to estimate utilities associated with treatment approaches for TDT. Methods General population respondents in England valued eight health state vignettes (developed with clinician, patient, and parent input) in time trade-off interviews. Results A total of 207 participants completed interviews (49.8% female; mean age = 43.2 years). Mean (SD) utilities for the pre-transplant health states were 0.73 (0.25) with oral chelation and 0.63 (0.32) with subcutaneous chelation. Mean utilities for the transplant year were 0.62 (0.35) for gene addition therapy, 0.47 (0.39) for allo-HSCT, and 0.39 (0.39) for allo-HSCT with acute GvHD. Post-transplant utilities were 0.93 (0.15) for transfusion independent, 0.75 (0.25) for 60% transfusion reduction, and 0.51 (0.38) for chronic GvHD. Acute and chronic GvHD were associated with significant disutility (acute = − 0.09, p < 0.0001; chronic = − 0.42, p < 0.0001). Conclusions Utilities followed expected patterns, with logical differences between treatment options for TDT and substantially greater utility for transfusion independence than for ongoing treatment involving transfusion and chelation. These utilities may be useful in cost-utility models estimating the value of treatments for TDT.
