Pentraxin-3 - a potential biomarker in ANCA-associated vasculitis.

OBJECTIVE: The aim of this study was to investigate pentraxin-3 (PTX3) as a potential biomarker of inflammatory activity in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) at baseline and 6 month follow-up in a longitudinal cohort. METHOD: Plasma PTX3 levels were measured in 79 newly diagnosed or relapsing AAV patients at baseline and 6 month follow-up, and in 23 healthy controls. Urinary PTX3 levels were measured in 34 of the patients. C-reactive protein (CRP), creatinine, and albuminuria were measured and the cumulative glucocorticoid dose at inclusion was calculated. The Birmingham Vasculitis Activity Score (BVAS) was assessed at baseline and follow-up. RESULTS: Plasma PTX3 levels were significantly higher at baseline than at 6 months (2.85 vs 1.23 ng/mL, p < 0.001). Plasma and urinary PTX3 levels correlated with BVAS at baseline (ρ = 0.45, p < 0.001, and ρ = 0.49, p = 0.008, respectively). A significant correlation between both plasma and urinary PTX3 levels and estimated glomerular filtration rate and albuminuria was found. However, there was no correlation between plasma and urinary PTX3 levels. At baseline, plasma and urinary PTX3 levels were significantly higher in patients with kidney involvement. PTX3 levels did not correlate with CRP, nor was there a correlation between CRP levels and BVAS at baseline. CONCLUSION: Plasma and urinary PTX3 seem to reflect disease activity in AAV better than the commonly used CRP. PTX3 may have a potential role as a biomarker in monitoring disease activity in AAV patients, particularly in patients with kidney involvement.

Validity and reliability of the Swedish version of the Self-Efficacy for Managing Chronic Disease scale for individuals with systemic sclerosis.

OBJECTIVE: To investigate aspects of validity and reliability of the Swedish version of the Self-Efficacy for Managing Chronic Disease (SEMCD-Swe) scale in systemic sclerosis (SSc). METHOD: A forward-backward translation procedure was used. Content validity was assessed through interviews with 11 people with SSc and 10 healthcare professionals. Construct validity, internal consistency, test-retest reliability, and floor and ceiling effects were evaluated in 104 SSc patients. RESULTS: The content validity of the SEMCD-Swe was interpreted as satisfactory, but some adjustments were made to increase the understanding. Confirmatory factor analysis supported a single-factor structure. Moderate to strong correlations between the SEMCD-Swe and Scleroderma Health Assessment Questionnaire; Multidimensional Assessment of Fatigue; Patient Health Questionnaire-8 (rs = -0.4 to -0.7), and RAND-36 subscales (rs = 0.5 to 0.7) were found. Weak correlations were found between SEMCD-Swe and modified Rodnan skin score; and disease severity of peripheral vascular and lung (rs = -0.1 to -0.2) and kidney (rs = 0.1) systems (Medsger severity scale). Cronbach's alpha was sufficient (0.85) and corrected item-to-total correlations were good (≥ 0.50). The intraclass correlation coefficient for the total score was sufficient (0.82). No floor or ceiling effects were found. CONCLUSION: Support for construct validity was indicated, as the SEMCD-Swe in SSc show a single-factor structure and is more strongly associated with pain, fatigue, depressive symptoms, interferences with daily activities, disability, and quality of life than with disease severity. Our results also indicate support for content validity and reliability. However, the responsiveness of the SEMCD-Swe needs to be tested.

Centralized repeated resectability assessment of patients with colorectal liver metastases during first-line treatment: prospective study.

BACKGROUND: Metastasectomy is probably underused in metastatic colorectal cancer. The aim of this study was to investigate the effect of centralized repeated assessment on resectability rate of liver metastases. METHODS: The prospective RAXO study was a nationwide study in Finland. Patients with treatable metastatic colorectal cancer at any site were eligible. This planned substudy included patients with baseline liver metastases between 2012 and 2018. Resectability was reassessed by the multidisciplinary team at Helsinki tertiary referral centre upfront and twice during first-line systemic therapy. Outcomes were resectability rates, management changes, and survival. RESULTS: Of 812 patients included, 301 (37.1 per cent) had liver-only metastases. Of these, tumours were categorized as upfront resectable in 161 (53.5 per cent), and became amenable to surgery during systemic treatment in 63 (20.9 per cent). Some 207 patients (68.7 per cent) eventually underwent liver resection or ablation. At baseline, a discrepancy in resectability between central and local judgement was noted for 102 patients (33.9 per cent). Median disease-free survival (DFS) after first resection was 20 months and overall survival (OS) 79 months. Median OS after diagnosis of metastatic colorectal cancer was 80, 32, and 21 months in R0-1 resection, R2/ablation, and non-resected groups, and 5-year OS rates were 68, 37, and 9 per cent, respectively. Liver and extrahepatic metastases were present in 511 patients. Of these, tumours in 72 patients (14.1 per cent) were categorized as upfront resectable, and 53 patients (10.4 per cent) became eligible for surgery. Eventually 110 patients (21.5 per cent) underwent liver resection or ablation. At baseline, a discrepancy between local and central resectability was noted for 116 patients (22.7 per cent). Median DFS from first resection was 7 months and median OS 55 months. Median OS after diagnosis of metastatic colorectal cancer was 79, 42, and 17 months in R0-1 resection, R2/ablation, and non-resected groups, with 5-year OS rates of 65, 39, and 2 per cent, respectively. CONCLUSION: Repeated centralized resectability assessment in patients with colorectal liver metastases improved resection and survival rates.

Perceptions of nurses on inter-shift handover: A descriptive study in Hospital Kuala Lumpur, Malaysia.

INTRODUCTION: The quality of information and efficiency in the practice and care environments are important aspects of nursing care. The use of a reliable and valid scale can monitor the quality of handover and provide information for continuous improvement of practice. This study aims to describe the perception of nurses, on the domains of quality of information, efficiency, interaction and support and patient involvement. METHOD: A cross-sectional descriptive study was conducted among 450 nurses from 37 wards in Hospital Kuala Lumpur. Nurses on shift duty were recruited by convenience sampling from the Medical, Surgery, Obstetrics & Gynaecology, Orthopaedic and Paediatric wards. Using a validated questionnaire (Handover Evaluation Scale), nurses self-rated their perceptions using a 7-point scale and provided open-ended responses to the strengths and challenges that they faced. Descriptive and inferential analyses were done while open-ended questions were summarised based on key themes. RESULTS: A total of 414 nurses completed the survey (92.0% response rate). Nurses had an overall mean (SD) perception score of 5.01 (SD 0.56). They perceived good interaction and support during handover and on the quality of information that they received, with mean scores of 5.54 (SD 0.79) and 5.19 (SD 0.69), respectively. There was an association between the departments where the nurses worked and their overall perceptions on nursing handover (p<0.001). Interruptions being the most common theme emerged from the open-ended section. CONCLUSION: Despite having substantial interaction and support amongst nurses, opportunities for improvements were noted. Improvements in the quality of handover information and reducing interruptions should be the main emphases as these were perceived to be essential in the current handover practices by nurses.

Muscle endurance, strength, and active range of motion in patients with different subphenotypes in systemic sclerosis: a cross-sectional cohort study.

OBJECTIVE: Proximal muscle weakness is common in patients with systemic sclerosis (SSc). Dynamic muscle endurance, muscle strength in the lower extremities, and active range of motion (AROM) in the upper extremities are less studied. We investigated functional muscle endurance, strength, and AROM, and explored differences depending on skin and/or lung involvement in SSc patients. METHOD: The study divided 205 patients with limited/diffuse cutaneous systemic sclerosis (lcSSc/dcSSc) into no-mild and moderate-end-stage lung involvement, the latter based on the Medsger disease severity score. Dynamic muscle endurance in shoulder and hip flexion was assessed by the Functional Index-2, lower extremity muscle strength by the Timed-Stands Test (TST), and shoulder-arm AROM by the Functional Shoulder Assessment (FSA). RESULTS: Shoulder and hip flexion muscle endurance were reduced in relation to reference values median (IQR) [53% (27-100%) and 40% (23-90%), respectively, p < 0.001]. Patients with moderate-end-stage lung involvement had less endurance in shoulder [39% (21-71%) and hip flexion 35% (20-70%)] than patients with no-mild lung involvement [57% (33-99%) and 48% (28-100%), p < 0.05]. All patients, regardless of subtype/grouping, needed longer to complete the TST [21 s (17-27 s)] compared to reference values [17 s (15-18 s), p < 0.001], and patients with moderate-end-stage lung involvement had worse TST score than patients with no-mild lung involvement,  [25 s (18-30 s) vs 19 s (16-25 s), p < 0.001]. The FSA sum scores were lower compared with reference values (p < 0.01). DcSSc patients had a lower FSA-sum score [53 (48-57)] than lcSSc patients [57 (52-60), p < 0.01]. CONCLUSION: SSc patients have markedly reduced muscle endurance in the upper and lower extremities, reduced muscle strength in the lower extremities, and impaired AROM in the shoulders and arms. Patients with moderate-end-stage lung involvement had more impaired muscle endurance and strength but no differences were found between lcSSc and dcSSc patients. Not only muscle strength, but also dynamic muscle endurance should be measured in SSc patients.

Geographic variation in the use of lymphadenectomy and external-beam radiotherapy for endometrial cancer: a cross-sectional analysis of population-based data.

OBJECTIVE: To quantify geographic variation in the use of lymphadenectomy and/or external-beam radiotherapy (EBRT) for endometrial cancer in England. DESIGN: Cross-sectional analysis of population-based data. SETTING: English cancer registry data, linked to chemotherapy, radiotherapy and hospital episodes statistics data. POPULATION: Twenty-two thousand four hundred and eighty-three women with endometrial cancer presenting without clinical or radiological evidence of distant metastatic spread, diagnosed in England from 2013 to 2016. METHODS: Proportions of patients receiving lymphadenectomy and/or EBRT were compared across 19 Cancer Alliances, to identify variations in clinical practice. Two separate logistic regression models assessed the impact on variation of adjustment for tumour and patient characteristics. MAIN OUTCOME MEASURES: Receipt of lymphadenectomy, receipt of EBRT. RESULTS: There was substantial variation by Cancer Alliance in the adjusted proportion of women with endometrial cancer receiving lymphadenectomy (range 5% [95% CI 4-6%] to 48% [95% CI 45-52%]) and EBRT (range 10% [95% CI 7-12%] to 31% [95% CI 28-33%]), after adjusting for variation in pathological grade, age, comorbidities, deprivation, ethnic group and (EBRT only) FIGO stage. Different approaches to clinical practice were identified; (i) one Cancer Alliance had significantly higher than average lymphadenectomy and significantly lower than average EBRT use, (ii) three had high use of both lymphadenectomy and EBRT, (iii) one had low lymphadenectomy use and high EBRT use, and (iv) three had low use of both lymphadenectomy and EBRT. CONCLUSIONS: Lymphadenectomy is probably used to triage for EBRT when lymphadenectomy use is high and EBRT use is low. This is probably a result of variation in local endometrial cancer management guidelines, suggesting that UK recommendations should be clarified. TWEETABLE ABSTRACT: There is geographic variation in England in the use of lymphadenectomy and radiotherapy to treat endometrial cancer.

Decreasing incidence of cancer after liver transplantation-A Nordic population-based study over 3 decades.

Cancer remains one of the most serious long-term complications after liver transplantation (LT). Data for all adult LT patients between 1982 and 2013 were extracted from the Nordic Liver Transplant Registry. Through linkage with respective national cancer-registry data, we calculated standardized incidence ratios (SIRs) based on country, sex, calendar time, and age-specific incidence rates. Altogether 461 cancers were observed in 424 individuals of the 4246 LT patients during a mean 6.6-year follow-up. The overall SIR was 2.22 (95% confidence interval [CI], 2.02-2.43). SIRs were especially increased for colorectal cancer in recipients with primary sclerosing cholangitis (4.04) and for lung cancer in recipients with alcoholic liver disease (4.96). A decrease in the SIR for cancers occurring within 10 years post-LT was observed from the 1980s: 4.53 (95%CI, 2.47-7.60), the 1990s: 3.17 (95%CI, 2.70-3.71), to the 2000s: 1.76 (95%CI, 1.51-2.05). This was observed across age- and indication-groups. The sequential decrease for the SIR of non-Hodgkin lymphoma was 25.0-12.9-7.53, and for nonmelanoma skin cancer 80.0-29.7-10.4. Cancer risk after LT was found to be decreasing over time, especially for those cancers that are strongly associated with immunosuppression. Whether immunosuppression minimization contributed to this decrease merits further study.

Recurrence of vulval intraepithelial neoplasia following treatment with cidofovir or imiquimod: results from a multicentre, randomised, phase II trial (RT3VIN).

OBJECTIVE: To compare the recurrence rates after complete response to topical treatment with either cidofovir or imiquimod for vulval intraepithelial neoplasia (VIN) 3. DESIGN: A prospective, open, randomised multicentre trial. SETTING: 32 general hospitals located in Wales and England. POPULATION OR SAMPLE: 180 patients were randomised consecutively between 21 October 2009 and 11 January 2013, 89 to cidofoovir (of whom 41 completely responded to treatment) and 91 to imiquimod (of whom 42 completely responded to treatment). METHODS: After 24 weeks of treatment, complete responders were followed up at 6-monthly intervals for 24 months. At each visit, the Common Terminology Criteria for Adverse Events (CTCAE) v3.0 was assessed and any new lesions were biopsied for histology. MAIN OUTCOME MEASURES: Time to histologically confirmed disease recurrence (any grade of VIN). RESULTS: The median length of follow up was 18.4 months. At 18 months, more participants were VIN-free in the cidofovir arm: 94% (95% CI 78.2-98.5) versus 71.6% (95% CI 52.0-84.3) [univariable hazard ratio (HR) 3.46, 95% CI 0.95-12.60, P = 0.059; multivariable HR 3.53, 95% CI 0.96-12.98, P = 0.057). The number of grade 2+ events was similar between treatment arms (imiquimod: 24/42 (57%) versus cidofovir: 27/41 (66%), χ2 = 0.665, P = 0.415), with no grade 4+. CONCLUSIONS: Long-term data indicates a trend towards response being maintained for longer following treatment with cidofovir than with imiquimod, with similar low rates of adverse events for each drug. Adverse event rates indicated acceptable safety of both drugs TWEETABLE ABSTRACT: Long-term follow up in the RT3VIN trial suggests cidofovir may maintain response for longer than imiquimod.

Decentralised black water treatment by combined auto-thermal aerobic digestion and ammonia - A pilot study optimising treatment capacity.

Partial heating of black water by auto-thermal aerobic digestion was combined with the addition of 1% w/w urea and monitoring of pathogens and indicator organisms over a 21-day period. After initial mixing, the 160 m3 black water (60 m3 heated and 100 m3 non-heated) was left undisturbed. The urea was confirmed to be fully degraded into ammonia (5.1 g N L-1) first after 14 days, while the pH stabilised at around 9.2 after one week. The initial temperature of 17 °C fell by 6 °C during the study. E. coli and Salmonella spp., which are sensitive to ammonia, were inactivated during the first few days of the study, despite the urea only being partly hydrolysed. At day 14, f-RNA bacteriophages could also no longer be detected. The more persistent somatic coliphages, Enterococcus spp. and Ascaris eggs, showed significant but slow inactivation. The treatment proved to be efficient with regards to salmonella, which is a target pathogen in the Swedish context, but for parasite egg inactivation a higher temperature was required. The treatment would benefit from more frequent stirring to speed up the hydrolysis of urea and thus improve treatment efficiency. The alternative treatment scheme could increase capacity by 2.4 times, albeit with a 40% higher cost per volume due to the increased use of urea.

A rare case of non-contact salter harris type 2 fracture of distal femur during a football match.

Distal femoral physeal fractures in adolescents are often due to high velocity injuries. We present an unusual case of a non-contact distal femoral physeal fracture that occurred during a football match. A torsional force had been directed at the fracture site occurring at the growth plate causing a transverse fracture rather than a spiral fracture. It is important to be aware that such fractures can occur despite little or no evidence of contact. These type of injuries should also be treated as an emergency to reduce the risk of further complications.

The role of PET/CT amyloid Imaging compared with Tc99m-HMPAO SPECT imaging for diagnosing Alzheimer's disease.

BACKGROUND: Imaging such as Tc99m-HMPAO single photon emission computed tomography (SPECT), and positron emission tomography/ computed tomography (PET/CT) amyloid scans are used to aid the diagnosis of Alzheimer's disease (AD). OBJECTIVE: We aimed to correlate the ability of these modalities to differentiate Probable AD and Possible AD using the clinical diagnosis as a gold standard. We also investigated the correlation of severity of amyloid deposit in the brain with the diagnosis of AD. METHODS: A retrospective study of 47 subjects (17 Probable AD and 30 Possible AD) who were referred for PET/CT amyloid scans to our centre was conducted. Hypoperfusion in the temporo-parietal lobes on Tc99m-HMPAO SPECT and loss of grey-white matter contrast in cortical regions on PET/CT Amyloid scans indicating the presence of amyloid ß deposit were qualitatively interpreted as positive for AD. SPECT and PET/CT were also read in combination (Combo reading). The severity of amyloid ß deposit was semiquantitatively assessed in a visual binary method using a scale of Grade 0-4. The severity of amyloid ß deposit was assessed in a visual binary method and a semi-quantitative method using a scale of Grade 0-4. RESULTS: There was significant correlation of Tc99m-HMPAO SPECT, PET/CT amyloid findings and Combo reading with AD. The sensitivity, specificity, PPV and NPV were 87.5%, 73.7%, 58.3% and 93.3% (SPECT); 62.5%, 77.4%, 58.8% and 80.0% (PET/CT) and 87.5%, 84.2%, 70.0% and 30.0% (Combo reading) respectively. The grade of amyloid deposition was not significantly correlated with AD (Spearman's correlation, p=0.687). CONCLUSION: There is an incremental benefit in utilizing PET/CT amyloid imaging in cases with atypical presentation and indeterminate findings on conventional imaging of Alzheimer's disease.

Troponin I and echocardiography in patients with systemic sclerosis and matched population controls.

OBJECTIVES: Cardiac manifestations in systemic sclerosis (SSc) are associated with poor prognosis. Few studies have investigated cardiac troponins in SSc. We studied the relationships between echocardiographic abnormalities, cardiac biomarkers, and disease manifestations in a population-based cohort of patients with SSc and controls. METHOD: The study comprised 110 patients with SSc and 105 age- and sex-matched population-based controls. We examined ventricular function, heart valves, and estimated pulmonary arterial pressure (ePAP) by echocardiography in all participants. Disease characteristics, manifest ischaemic heart disease (IHD), and measurements of N-terminal prohormone brain natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin I (hs-cTnI) were tabulated. RESULTS: NT-proBNP and hs-cTnI levels were higher in SSc patients than controls. Both NT-proBNP and hs-cTnI were associated with the presence of echocardiographic abnormalities. Forty-four SSc patients and 23 control subjects had abnormal echocardiograms (p = 0.002). As a group, SSc patients had lower (but normal) left ventricular ejection fraction (LVEF, p = 0.02), more regional hypokinesia (p = 0.02), and more valve regurgitations (p = 0.01) than controls. Thirteen patients and four controls had manifest IHD. Decreased right ventricular (RV) function (n = 7) and elevated ePAP (n = 15) were exclusively detected among SSc patients. CONCLUSIONS: Both NTproBNP and hs-cTnI were associated with echocardiographic abnormalities, which were more prevalent in SSc patients than in controls. Our results thus suggest that hs-cTnI could be a potential cardiac biomarker in SSc. Low RV function and signs of pulmonary hypertension (PH) were uniquely found in the SSc group. SSc patients had more valve regurgitation than controls, an observation that warrants more clinical attention.

Self-reported physical capacity and activity in patients with systemic sclerosis and matched controls.

OBJECTIVE: The aim was to investigate differences in self-reported physical capacity and activity between systemic sclerosis (SSc) patients and population-based controls, as well as between patients with normal-mild, or moderate-severe, lung disease and their respective controls. METHOD: The study included 106 patients fulfilling the American College of Rheumatology SSc criteria and 106 controls, individually matched for age and gender. Patients were subdivided into normal-mild and moderate-severe lung disease based on results from pulmonary function tests and SSc severity scale. Participants answered questions regarding physical capacity and activity, exercise, and time spent sitting. RESULTS: SSc patients reported overall lower capacity for walking, jogging, and running (p < 0.001), and more limiting factors for physical capacity than controls (p < 0.001). Both patients with normal-mild and moderate-severe lung disease also reported lower overall physical capacity than their respective controls (p = 0.001, p < 0.001). Normal-mild lung disease patients reported pain more often than their controls (p < 0.05), whereas moderate-severe lung disease patients reported cardiopulmonary disease (p < 0.001) and reduced muscle strength (p = 0.03) as limiting factors for physical capacity more often than their controls. More patients than controls had 'never exercised' for at least 30 min per occasion within the past year (28% vs 15%, p = 0.03); however, there were no differences overall between patients and controls in frequency of exercise, physical activity, or time spent sitting. CONCLUSION: Although SSc patients reported lower physical capacity and more limiting factors for physical capacity than controls, there were no differences in reported physical activity and time spent sitting. Further development of physical activity programmes for SSc patients, especially for patients who never exercise or have physical impairments, is needed.

MIR137 variants identified in psychiatric patients affect synaptogenesis and neuronal transmission gene sets.

Sequence analysis of 13 microRNA (miRNA) genes expressed in the human brain and located in genomic regions associated with schizophrenia and/or bipolar disorder, in a northern Swedish patient/control population, resulted in the discovery of two functional variants in the MIR137 gene. On the basis of their location and the allele frequency differences between patients and controls, we explored the hypothesis that the discovered variants impact the expression of the mature miRNA and consequently influence global mRNA expression affecting normal brain functioning. Using neuronal-like SH-SY5Y cells, we demonstrated significantly reduced mature miR-137 levels in the cells expressing the variant miRNA gene. Subsequent transcriptome analysis showed that the reduction in miR-137 expression led to the deregulation of gene sets involved in synaptogenesis and neuronal transmission, all implicated in psychiatric disorders. Our functional findings add to the growing data, which implicate that miR-137 has an important role in the etiology of psychiatric disorders and emphasizes its involvement in nervous system development and proper synaptic function.

Thirty-day postoperative mortality for endometrial carcinoma in England: a population-based study.

OBJECTIVE: To quantify trends in 30-day mortality following surgery for endometrial carcinoma in England, and investigate hospital- and geographical-level variations. DESIGN: Retrospective population-based observational study using cancer registration and Hospital Episodes Statistics data. SETTING: England. POPULATION: Women diagnosed with endometrial carcinoma (ICD10 C54-C55 excluding sarcomas and malignant mixed Mullerian tumours) between 2000 and 2009 who were treated surgically (n = 38 332). METHODS: Random effects logistic regression model of postoperative mortality rates, adjusting for patient- and/or tumour-level factors (namely age, income deprivation, year of diagnosis, FIGO stage and grade). Case-mix adjusted postoperative mortality rates for hospitals and cancer networks were derived from the model. Multiple imputation was used to account for missing stage and grade data. MAIN OUTCOME MEASURES: 30-day postoperative mortality rate. RESULTS: For 2000-2009, the percentage of women dying within 30 days of surgery for endometrial carcinoma was very low at 0.61% (235 deaths), and decreased from 0.70% in 2000-2001 to 0.48% in 2008-2009. Postoperative mortality rates were lower for laparoscopic surgery, and higher for older women, those with advanced stage disease and high-grade tumours. Crude and case-mix adjusted results indicated that one hospital had a higher postoperative mortality rate than expected. CONCLUSIONS: The postoperative mortality rate for endometrial carcinoma in England is low and has improved since 2000, with increasing use of laparoscopic surgery. Postoperative mortality rates differed by surgical approach, patient age, disease stage and tumour grade. Only one hospital had a higher postoperative mortality rate than expected after adjusting for patient case-mix. TWEETABLE ABSTRACT: More women with endometrial cancer but better 30-day survival after surgery since 2000.

Benchmarking of surgical complications in gynaecological oncology: prospective multicentre study.

OBJECTIVE: To explore the impact of risk-adjustment on surgical complication rates (CRs) for benchmarking gynaecological oncology centres. DESIGN: Prospective cohort study. SETTING: Ten UK accredited gynaecological oncology centres. POPULATION: Women undergoing major surgery on a gynaecological oncology operating list. METHODS: Patient co-morbidity, surgical procedures and intra-operative (IntraOp) complications were recorded contemporaneously by surgeons for 2948 major surgical procedures. Postoperative (PostOp) complications were collected from hospitals and patients. Risk-prediction models for IntraOp and PostOp complications were created using penalised (lasso) logistic regression using over 30 potential patient/surgical risk factors. MAIN OUTCOME MEASURES: Observed and risk-adjusted IntraOp and PostOp CRs for individual hospitals were calculated. Benchmarking using colour-coded funnel plots and observed-to-expected ratios was undertaken. RESULTS: Overall, IntraOp CR was 4.7% (95% CI 4.0-5.6) and PostOp CR was 25.7% (95% CI 23.7-28.2). The observed CRs for all hospitals were under the upper 95% control limit for both IntraOp and PostOp funnel plots. Risk-adjustment and use of observed-to-expected ratio resulted in one hospital moving to the >95-98% CI (red) band for IntraOp CRs. Use of only hospital-reported data for PostOp CRs would have resulted in one hospital being unfairly allocated to the red band. There was little concordance between IntraOp and PostOp CRs. CONCLUSION: The funnel plots and overall IntraOp (≈5%) and PostOp (≈26%) CRs could be used for benchmarking gynaecological oncology centres. Hospital benchmarking using risk-adjusted CRs allows fairer institutional comparison. IntraOp and PostOp CRs are best assessed separately. As hospital under-reporting is common for postoperative complications, use of patient-reported outcomes is important. TWEETABLE ABSTRACT: Risk-adjusted benchmarking of surgical complications for ten UK gynaecological oncology centres allows fairer comparison.

Predictors of complications in gynaecological oncological surgery: a prospective multicentre study (UKGOSOC-UK gynaecological oncology surgical outcomes and complications).

BACKGROUND: There are limited data on surgical outcomes in gynaecological oncology. We report on predictors of complications in a multicentre prospective study. METHODS: Data on surgical procedures and resulting complications were contemporaneously recorded on consented patients in 10 participating UK gynaecological cancer centres. Patients were sent follow-up letters to capture any further complications. Post-operative (Post-op) complications were graded (I-V) in increasing severity using the Clavien-Dindo system. Grade I complications were excluded from the analysis. Univariable and multivariable regression was used to identify predictors of complications using all surgery for intra-operative (Intra-op) and only those with both hospital and patient-reported data for Post-op complications. RESULTS: Prospective data were available on 2948 major operations undertaken between April 2010 and February 2012. Median age was 62 years, with 35% obese and 20.4% ASA grade ⩾3. Consultant gynaecological oncologists performed 74.3% of operations. Intra-op complications were reported in 139 of 2948 and Grade II-V Post-op complications in 379 of 1462 surgeries. The predictors of risk were different for Intra-op and Post-op complications. For Intra-op complications, previous abdominal surgery, metabolic/endocrine disorders (excluding diabetes), surgical complexity and final diagnosis were significant in univariable and multivariable regression (P<0.05), with diabetes only in multivariable regression (P=0.006). For Post-op complications, age, comorbidity status, diabetes, surgical approach, duration of surgery, and final diagnosis were significant in both univariable and multivariable regression (P<0.05). CONCLUSIONS: This multicentre prospective audit benchmarks the considerable morbidity associated with gynaecological oncology surgery. There are significant patient and surgical factors that influence this risk.

Enhanced recovery protocol after liver resection.

BACKGROUND: Enhanced recovery protocols (ERPs) accelerate patient recovery and shorten hospital stay by optimization of perioperative care. However, experience with ERPs is still limited in liver surgery. METHODS: The implementation of a multimodal ERP was studied in patients who underwent open and laparoscopic liver surgery. An opioid-sparing pain treatment was chosen together with early mobilization and oral feeding, as well as restricted use of abdominal drains and catheters. Date to discharge, postoperative complications and patient satisfaction were assessed. A historical cohort of patients who underwent liver resection served as a control group. RESULTS: Some 134 liver resections (126 open, 8 laparoscopic) were performed between April 2013 and March 2014. Operations were carried out mostly for malignant liver tumours. One hundred and six (79.1 per cent) of the 134 patients were discharged by the fifth postoperative day. The median (range) postoperative hospital stay was 4 (2-11) days, compared with 6 (4-16) days for the control group (P < 0.001). Only four patients in the ERP group were readmitted and the 30-day mortality rate was zero. CONCLUSION: An ERP for perioperative care after liver surgery was introduced safely and effectively. Discharge within 4 days is achievable with no increase in adverse events and good patient satisfaction.

Increased Serum Levels of the IL-33 Neutralizing sST2 in Limited Cutaneous Systemic Sclerosis.

The pathophysiology of both limited cutaneous systemic sclerosis (lcSSc) and diffuse cutaneous SSc (dcSSc), representing two subtypes of an autoimmune disease of the connective tissue, is still enigmatic. Life-limiting, progressive fibrotic changes as a consequence of vasculopathy and autoimmunity are characteristic in varying extent for lcSSc and dcSSc. Previously, an increased IL-33 serum concentration in early phase SSc patients and an elevated tissue expression of its receptor, ST2L, on endothelial cells (EC) were described. While suggested as a biomarker for fibrotic diseases, for example liver fibrosis, the role of soluble ST2 (sST2) in the pathological processes and its contribution to vascular fibrosis in SSc has not been investigated. Here, we showed that sST2 is elevated in late phase limited cutaneous SSc (lcSSc) as compared to patients with shorter disease duration or with the diffuse subtype of SSc. We demonstrated that sST2, not IL-33, is significantly increased in serum of lcSSc patients with disease duration over 9 years. Soluble ST2 was not elevated in healthy controls or in SSc patients with early skin involvement or disease duration shorter than 9 years. Furthermore, we observed that sST2 serum levels were lowered by iloprost (prostacyclin) treatment. After 5 days of iloprost infusion, sST2 serum levels fell in 6 of 7 patients. Therefore, we not only like to propose sST2 as a biomarker for progressive vascular fibrosis, but moreover, suggest that the involvement of sST2 in the pathogenesis of lcSSc may be exploited therapeutically.

18F-FDG PET/CT as a potential predictor of survival in patient with oesophageal cancer: a preliminary result.

AIMS: A study was undertaken to investigate the value of pretreatment PET-CT in predicting survival in patients with oesophageal cancer (OC). METHODS: Between June 2010 and December 2011, 18 consecutive OC patients median (61.00 ± 12.07 years) with median survival of 7.5 month had a pretreatment PET-CT scan. Staging of the disease was made in accordance to the American Joint Committee on Cancer staging system (7th edition) and grouped as stage I-IIA and stage IIB-IV. Maximum standardized uptake value (SUVmax), size of a primary tumour and the presence of fluorodeoxyglucose (FDG)-avid lymph nodes were evaluated for all patients. Survival was analysed using the Kaplan-Meier product limit method and Cox proportional hazards regression model. RESULTS: PET-CT stages I-IIA and IIB-IV had a 1-year survival of 50% and 25%, respectively. Patient with size of primary tumour (<4.5 cm) had significantly (p < 0.036) better survival than those with large size (>4.5 cm). Multivariate Cox regression analysis showed that SUVmax of >5.5 in the primary tumour [hazard ratio (HR) 23.017; 95% confidence interval, p = 0.038] and the presence of FDG-avid lymph node (HR 1.248; p = 0.028) were strongly predictive of poor overall survival on multivariate analysis. CONCLUSION: Pretreatment 18F-FDG PET-CT SUVmax of a primary tumour and the presence of FDG-avid lymph nodes independently predict survival in patients with oesophageal carcinoma which may potentially be used as surrogate markers for prognostic and therapeutic purposes.
