Hepatocellular Carcinoma : A Decade of Hospitalizations and Financial Burden in the United States

BACKGROUND: Despite a rise in the prevalence of hepatocellular carcinoma (HCC), data on HCC-related hospitalizations and financial burden are limited. The aim of this study was to evaluate temporal trends of HCC-related hospitalizations and evaluate its financial influence. MATERIALS AND METHODS: Patients with the diagnosis of HCC, as reported by International Classification of Diseases-Ninth Revision code, were identified from the National Inpatient Sample databases from 2002-2011. The national estimates of hospitalizations were derived using appropriate sample weights. The change in total average charges per each hospitalization over the study period was calculated after adjusting for inflation. RESULTS: Hospitalizations related to HCC have increased from 24,024 in 2002 to 50,609 in 2011. Of these admissions, HCC was the principal diagnosis in 10,762 and 16,350 subjects in 2002 and 2011, respectively. Most were white males (male: 70%; white: 55%). The overall inpatient mortality was significantly decreased from 13.5% in 2002 to 9.9% in 2011 (P < 0.01). The same trend was also observed for the length of hospital stay (6.5 versus 5.6 days in 2002 and 2011, respectively). The inflation-adjusted cost per hospitalization increased by approximately 47% during the study period. CONCLUSIONS: Despite the decrease in mortality rate and length-of-stay, hospitalizations and financial burden associated with HCC continued to increase between 2002 and 2011 in the United States

Proliferaton index in pituitary adenomas from a black African population

Background: The WHO has recognized a variant of pituitary adenomas with potential aggressive behaviour which have been termed atypical pituitary adenomas. This group of tumours are recognized by their mitotic rate of more than &gt;3%, p53 expression and invasion of surrounding structures. There has however been no study of the occurrence of these tumours in a black African population. This study is a preliminary attempt to examine this group of tumours in blacks.Methods: This study retrospectively reviewed fifty-seven histologically diagnosed and immunohistochemically characterized pituitary adenomas received in our department over a twenty-one year period. Specimens were stained with ki67, a nuclear marker of cell proliferation which has been identified as the single best predictor of atypical pituitary adenoma.Results: Twelve of the tumours showed atypical features with eight (67%) of these tumours being prolactinomas. Two of the tumours were gonadotrophs and two were null cell adenomas. There was no correlation with age or gender. Two of the tumours required neurosurgical re-exploration with one of these showing a higher mitotic index in the second biopsy.Conclusion: The study suggests similarity in the rate of occurrence of pituitary adenomas with atypical features in a black African population with what is seen in Caucasians. Prolactinomas constitute a significant percentage of the tumours with this feature.Keywords: Pituitary adenoma, Immunohistochemistry, Atypical, Ki6

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
