Deep Vein Thrombosis in Europe-Health-Related Quality of Life and Mortality.

OBJECTIVES: Deep vein thrombosis (DVT) is a major health-care burden in Europe, but exact estimates are lacking. This study reports results from the PREFER venous thromboembolism (VTE) study concerning health-related quality of life (HrQoL) and mortality of patients with DVT. METHODS: PREFER VTE was a prospective, observational study, conducted in 7 European countries, designed to provide data concerning treatment patterns, resource utilization, mortality, and QoL. First-time or recurrent patients with DVT were followed at 1, 3, 6, and 12 months. Health-related QoL-as measured by the EuroQoL 5-Dimension 5-Level instrument ( EQ-5D-5L)-was analyzed using Tobit regression with repeated measures, assessing the impact of baseline characteristics stratified by cancer activity. Mortality was analyzed using logistic regression. RESULTS: At baseline, patients with DVT had a 0.14 lower EQ-5D-5L index score (0.72 for total sample) compared to the reference UK population (0.85). The EQ-5D-5L index score improved from baseline to 12 months in patients with active cancer (from 0.70 to 0.79) and those without (0.72-0.87); 7.3% died within a year, a 5.2% excess mortality compared to the age- and gender-adfjusted general population. The 12-month mortality rate of DVT varied between 2.9% in the pooled data from Germany, Switzerland, or Austria and 15.4% in Italy. Furthermore, the mortality rate differed between patients with active cancer and those without (42.9% vs 4.7%). CONCLUSIONS: Deep vein thrombosis is associated with a substantial burden of illness in terms of HrQoL at baseline, which following treatment normalizes after 12 months and has a significant mortality rate. In addition, active cancer has a significant impact on mortality and the HrQoL of patients with DVT.

Relationship between fasting plasma glucose and incidence of diabetes in children and adolescents.

AIM: To investigate the appropriate fasting plasma glucose threshold by which to define prediabetes in children and adolescents, based on its ability to predict incident paediatric diabetes. METHODS: In a nationwide survey of diabetes and renal disease conducted between 1992 and 2000 in all school-aged children in Taiwan, those with abnormal results in repeated urine tests received further physical examination and blood tests. Students who had blood tests for at least two time points were selected for the present study (N = 12 119). The incidence of paediatric diabetes, adjusted hazard ratio and predictive power of fasting plasma glucose were analysed. RESULTS: The incidence of paediatric diabetes increased with increasing fasting plasma glucose levels. Groups with fasting plasma glucose >5.6 mmol/l had a higher adjusted hazard ratio. The adjusted hazard ratio of incident diabetes for participants with higher fasting plasma glucose rose continuously when using a higher threshold for fasting plasma glucose. The area under the receiver-operating characteristic curve for fasting plasma glucose was 0.628 for predicting paediatric diabetes. The association between fasting plasma glucose and incident paediatric diabetes and the area under the receiver-operating characteristic curve were similar in boys and girls and were higher in the age group 12-18 years. According to receiver-operating characteristic curve analysis, the optimal thresholds, sensitivity and specificity were 4.75 mmol/l, 65% and 51%, respectively, for those aged 6-11 years and 5.19 mmol/l, 60% and 73%, respectively, for those aged 12-18 years. CONCLUSION: Fasting plasma glucose is associated with the incidence of paediatric diabetes. The results of the present study can be used as reference data to suggest a cut-off value to define paediatric prediabetes.

Deep-vein thrombosis in Europe - Burden of illness in relationship to healthcare resource utilization and return to work.

OBJECTIVES: Deep-vein thrombosis (DVT) forms a major healthcare burden in Europe, but exact estimates concerning the economic burden on society are lacking. This study reports results from the PREFER in VTE study concerning resource utilization and absence from work in DVT patients. METHODS: The PREFER in VTE registry was a prospective, observational, multicenter study carried out in Europe (France, Italy, Spain, the UK, and DACH [Germany, Switzerland and Austria]), designed to provide data concerning treatment patterns, resource utilization, mortality and quality of life. Patients with a first-time and/or recurrent DVT, were recruited and followed for 12 months. Data about resource utilization concerns resource utilization related to DVT. Specifically, treatment pattern, re-hospitalization rate, length of hospital stay, ambulatory/office visit, and proportion of patients returning to work, were analyzed and presented. Subgroup analysis by country and active cancer were also conducted. The length of hospital stay was analyzed as a function of demographics, previous events and co-morbidities using zero-inflated binomial negative regression. Similarly, time until return to work was analyzed using Cox regression. RESULTS: A total of 2056 patients with DVT were recruited, with an average age of 60 years. Patients with active cancer were mostly treated with heparin (83.9%), while patients without active cancer were treated with combinations of heparin, VKA and DOACs. DOACs were less often used in Spain and Italy (<7.0%). Following the management of their initial DVT 20.5% of the patients with and 12.2% of patients without active cancer (n = 88; n = 1462) were hospitalized for on average 8.2 and 10.1 days, respectively. The hospitalization-rate was highest in Italy (16.7%) and lowest in France (7.7%). Furthermore, the average length of stay was highest in Italy (16.6 days) and lowest in DACH (5.2 days). Physician visits were highest in DACH (9.3), lowest in the UK (2.6). Of those working, 50% returned to work at 1 month; >30% did not return to work within the year. CONCLUSIONS: Medical treatment of DVT differed between patients with active cancer and those without. Post-VTE or VTE-related resource utilization differs remarkably between countries. Work-loss seems high, but questions may be raised concerning the causality due to the presence of co-morbidities.

Imaging and cancer of the cervix in low- and middle-income countries.

Cervix cancer is the fourth most common cancer globally but the second most cancer in women in resource-limited countries. It has remained a clinically-staged neoplasm as per the International Federation of Gynecology and Obstetrics staging classification. As the imaging machines are becoming more available worldwide, the resource-stratified guidelines recommended the inclusion of imaging whenever possible to guide treatment planning. In this report, the utility of imaging in low- and middle-income countries for diagnosis and treatment of cancer of the cervix will be reviewed.

Collaborations in gynecologic oncology education and research in low- and middle- income countries: Current status, barriers and opportunities.

Eighty-five percent of the incidents and deaths from cervical cancer occur in low and middle income countries. In many of these countries, this is the most common cancer in women. The survivals of the women with gynecologic cancers are hampered by the paucity of prevention, screening, treatment facilities and gynecologic oncology providers. Increasing efforts dedicated to improving education and research in these countries have been provided by international organizations. We describe here the existing educational and research programs that are offered by major international organizations, the barriers and opportunities provided by these collaborations and hope to improve the outcomes of cervical cancer through these efforts.

Association between thyroid dysfunction and dysglycaemia: a prospective cohort study.

AIMS: To compare the incidence of hyperglycaemia among participants with low, elevated and normal serum thyroid-stimulating hormone concentration, as well as the incidence of abnormal thyroid function test results among participants with normal blood glucose and those with hyperglycaemia. METHODS: In a prospective study, a cohort of 72 003 participants with normal, low and elevated serum thyroid-stimulating hormone concentration were followed from the study beginning to the first report of diabetes and prediabetes. A proportional hazards regression model was used to calculate the hazard ratios and 95% CIs for each outcome, adjusting for age, sex, education level, smoking, alcohol consumption and obesity. Analyses for the association between dysglycaemia and incident abnormal thyroid function test were also conducted. RESULTS: During a median 2.6 year follow-up, the incident rates for dysglycaemia, particularly prediabetes, were substantially higher in participants with elevated thyroid-stimulating hormone concentrations at baseline, while the rates for participants with normal and low thyroid-stimulating hormone were similar. After controlling for risk factors, participants with elevated thyroid-stimulating hormone retained a 15% increase in risk of prediabetes (adjusted hazard ratio 1.15, 95% CI 1.04-1.26), but were not at greater risk of diabetes (adjusted hazard ratio 0.96, 95% CI 0.64-1.44). By contrast, participants with normal and low thyroid-stimulating hormone concentrations had similar dysglycaemia risks. Participants with diabetes and prediabetes were not at greater risks of developing abnormal thyroid function test results when compared with participants with euglycaemia. CONCLUSIONS: People with elevated serum thyroid-stimulating hormone concentration are at greater risk of developing prediabetes. Whether this includes a greater risk of developing frank diabetes may require an extended period of follow-up to clarify.

Prescription trends and the selection of initial oral antidiabetic agents for patients with newly diagnosed type 2 diabetes: a nationwide study.

OBJECTIVES: The aim of this study was to examine the characteristics of patients, physicians, and medical facilities, and their association with prescriptions that do not include metformin as the initial oral antidiabetic agent. STUDY DESIGN: Observational, cross-sectional study. METHODS: Patients with incident type 2 diabetes between January 1, 2006, and December 31, 2010, were identified from the Taiwan National Insurance Research Database. We describe trends in the initial prescription of antidiabetic medications that do not contain metformin during the study period. A multivariable logistic model and a multilevel linear model were used in the analysis of factors at a range of levels (patient, physician, and medical facility), which may be associated with the selection of oral antidiabetic drugs. RESULTS: During the study period, the proportion of prescriptions that did not include metformin declined from 43.8% to 26.2%. Male patients were more likely to obtain non-metformin prescriptions (adjusted odds ratio [OR]: 1.15; 95% confidence interval [CI]: 1.08-1.23), and the likelihood that a patient would be prescribed a non-metformin prescription increased with age. Physicians aged ≥35 years and those with specialties other than endocrinology tended to prescribe non-metformin prescriptions. Metformin was less commonly prescribed in for-profit hospitals (adjusted OR: 1.34, 95% CI: 1.11-1.61) and hospitals in smaller cities (adjusted OR: 1.28, 95% CI: 1.05-1.57) and rural areas (adjusted OR: 1.83, 95% CI: 1.32-2.54). CONCLUSIONS: Disparities continue to exist in clinical practice with regard to the treatment of diabetes. These inequalities appear to be linked to a variety of factors related to patients, physicians, and medical facilities. Further study will be required to understand the effects of continuing medical education in enhancing adherence to clinical guidelines.

Detection and correlation of pre-operative, frozen section, and final pathology in high-risk endometrial cancer.

PURPOSE: To evaluate sensitivity and specificity of pre-operative and frozen section pathologic evaluation (FSA) in predicting high-risk (HR) histology endometrial cancer. MATERIALS AND METHODS: A retrospective analysis was performed on all patients diagnosed with endometrial cancer at a single institution. Medical records were abstracted for baseline characteristics, surgical reports for staging, and final histology was confirmed by a gynecologic pathologist. RESULTS: 868 patients were identified. Of these, 118 had Grade 3 endometrioid, 36 clear cell carcinoma (CCC), 47 carcinosarcoma (CS), and 84 uterine papillary serous carcinoma (UPSC) histology. Endometrial biopsy (EMB) had an overall sensitivity of 90%, 77% for low grade, 78% for HR, with a specificity of 0%. For dilation and curettage (D&C), overall sensitivity was 85%, 69% for low grade, and 77% for HR. Specificity was 33%. Sensitivities for combined pre-operative testing for G3 endometrioid, CCC, CS, and UPSC were: 56%, 28%, 72%, and 60%, respectively. For frozen section analysis (FSA), overall sensitivity was 77%, and 67% for low and high grade. For G3 endometrioid, CCC, CS, and UPSC, sensitivities were 57%, 20%, 74%, 32%, respectively. Specificity was 95%. FSA identified an additional six patients (8%) with UPSC, CCC or CS that were pre-operatively low risk, providing an 8% improvement in sensitivity but decreased specificity. CONCLUSIONS: Pre-operative EMB and D&C are overall very sensitive for detecting endometrial cancer; however, sensitivity decreases with HR histology. Pre-op testing will miss 28% of HR diagnoses and FSA provides an opportunity to identify some patients with UPSC, CCC, and CS. If pre-operative results suggest HR cancer, the surgeon should proceed with comprehensive surgical staging without an FSA.

Cost-effectiveness analysis of exenatide once-weekly versus dulaglutide, liraglutide, and lixisenatide for the treatment of type 2 diabetes mellitus: an analysis from the UK NHS perspective.

OBJECTIVE: To assess the cost-effectiveness of exenatide 2 mg once-weekly (EQW) compared to dulaglutide 1.5 mg QW, liraglutide 1.2 mg and 1.8 mg once-daily (QD), and lixisenatide 20 µg QD for the treatment of adult patients with type 2 diabetes mellitus (T2DM) not adequately controlled on metformin. METHODS: The Cardiff Diabetes Model was applied to evaluate cost-effectiveness, with treatment effects sourced from a network meta-analysis. Quality-adjusted life years (QALYs) were calculated with health-state utilities applied to T2DM-related complications, weight changes, hypoglycemia, and nausea. Costs (GBP £) included drug treatment, T2DM-related complications, severe hypoglycemia, nausea, and treatment discontinuation due to adverse events. A 40-year time horizon was used. RESULTS: In all base-case comparisons, EQW was associated with a QALY gain per patient; 0.046 vs dulaglutide 1.5 mg; 0.102 vs liraglutide 1.2 mg; 0.043 vs liraglutide 1.8 mg; and 0.074 vs lixisenatide 20 µg. Cost per patient was lower for EQW than for liraglutide 1.8 mg (-£2,085); therefore, EQW dominated liraglutide 1.8 mg. The cost difference per patient between EQW and dulaglutide 1.5 mg, EQW and liraglutide 1.2 mg, and EQW and lixisenatide 20 µg was £27, £103, and £738, respectively. Cost per QALY gained with EQW vs dulaglutide 1.5 mg, EQW vs liraglutide 1.2 mg, and EQW vs lixisenatide 20 µg was £596, £1,004, and £10,002, respectively. In the probabilistic sensitivity analysis, the probability that EQW is cost-effective ranged from 76-99%. CONCLUSION: Results suggest that exenatide 2 mg once-weekly is cost-effective over a lifetime horizon compared to dulaglutide 1.5 mg QW, liraglutide 1.2 mg QD, liraglutide 1.8 mg QD, and lixisenatide 20 µg QD for the treatment of T2DM in adults not adequately controlled on metformin alone.

Cost effectiveness of surgical versus non-surgical treatment of adults with displaced fractures of the proximal humerus: economic evaluation alongside the PROFHER trial.

AIMS: A pragmatic multicentre randomised controlled trial (PROFHER) was conducted in United Kingdom National Health Service (NHS) hospitals to evaluate the clinical effectiveness and cost effectiveness of surgery compared with non-surgical treatment for displaced fractures of the proximal humerus involving the surgical neck in adults. METHODS: A cost utility analysis from the NHS perspective was performed. Differences between surgical and non-surgical treatment groups in costs and quality adjusted life years (QALYs) at two years were used to derive an estimate of the cost effectiveness of surgery using regression methods. RESULTS: Patients randomised to receive surgical intervention accumulated mean greater costs and marginally lower QALYs than patients randomised to non-surgery. The surgical intervention cost a mean of £1758 more per patient (95% confidence intervals (CI) £1126 to £2389). Total QALYs for the surgical group were smaller than those for non-surgery -0.0101 (95% CI -0.13 to 0.11). The probability of surgery being cost effective was less than 10% given the current NICE willingness to pay at a threshold of £20 000 for an additional QALY. The results were robust to sensitivity analyses. DISCUSSION: The results suggest that current surgical treatment is not cost effective for the majority of displaced fractures of the proximal humerus involving the surgical neck in the United Kingdom's NHS. TAKE HOME MESSAGE: The results of this trial do not support the trend of increased surgical treatment for patients with displaced fractures of the proximal humerus involving the surgical neck within the United Kingdom NHS.

RUNX3 is a novel negative regulator of oncogenic TEAD-YAP complex in gastric cancer.

Runt-related transcription factor 3 (RUNX3) is a well-documented tumour suppressor that is frequently inactivated in gastric cancer. Here, we define a novel mechanism by which RUNX3 exerts its tumour suppressor activity involving the TEAD-YAP complex, a potent positive regulator of proliferative genes. We report that the TEAD-YAP complex is not only frequently hyperactivated in liver and breast cancer, but also confers a strong oncogenic activity in gastric epithelial cells. The increased expression of TEAD-YAP in tumour tissues significantly correlates with poorer overall survival of gastric cancer patients. Strikingly, RUNX3 physically interacts with the N-terminal region of TEAD through its Runt domain. This interaction markedly reduces the DNA-binding ability of TEAD that attenuates the downstream signalling of TEAD-YAP complex. Mutation of RUNX3 at Arginine 122 to Cysteine, which was previously identified in gastric cancer, impairs the interaction between RUNX3 and TEAD. Our data reveal that RUNX3 acts as a tumour suppressor by negatively regulating the TEAD-YAP oncogenic complex in gastric carcinogenesis.

A fixed denture for a child with epidermolysis bullosa simplex.

AIM: To report the caries treatment and delivery of a fixed denture for a 3-year-old girl with epidermolysis bullosa simplex (EBS). CASE REPORT: EBS is manifested on the skin or mucous membranes where skin separation is easily induced by trauma. Full- mouth rehabilitation under in-patient general anaesthesia was performed to the patient in conjunction with proper pre- and postoperative care. A fixed denture was fabricated and installed to replace the extracted teeth without later causing irritation on the mucosa. The prosthesis restored aesthetics and provided comfort without imposing the burden of compliance on the patient. CONCLUSION: Aided by meticulous pre- and postoperative care and oral hygiene reinforcement, comprehensive dental treatment coupled with fixed denture delivery can greatly improve the life quality and aesthetics for children with EBS.

Cardiovascular risks associated with second-line oral antidiabetic agents added to metformin in patients with Type 2 diabetes: a nationwide cohort study.

AIM: To compare the cardiovascular risks associated with second-line oral antidiabetic agents added to initial metformin therapy in a large nationwide observational study. METHODS: We conducted a nationwide retrospective cohort study using the Taiwan National Health Insurance database. A total of 36 118 users of different add-on oral antidiabetic agents (sulphonylureas, glinides, pioglitazone, α-glucosidase inhibitors and dipeptidyl peptidase-4 inhibitors) after initial metformin therapy were included in the analysis. The reference group was sulphonylureas added to metformin, the most commonly used combination regimen. The main outcomes of interest were hospitalizations for any cardiovascular event including acute myocardial infarction, congestive heart failure and ischaemic stroke. In the main analysis, all patients were followed within their initiation groups until the study end, disregarding any changes in treatment status over time. RESULTS: In intention-to-treat analyses, there was no difference in the risk of any cardiovascular event among the add-on combination treatment groups, but significantly lower risks of acute myocardial infarction were found for the glinides plus metformin treatment group (crude hazard ratio 0.52, adjusted hazard ratio 0.39; 95% CI 0.20-0.75) and for the α-glucosidase inhibitors plus metformin treatment group (crude hazard ratio 0.63, adjusted hazard ratio 0.54; 95% CI 0.31-0.95). No difference in risk of congestive heart failure or ischaemic stroke risk was found among the combination treatment groups. In secondary as-treated analyses, similar but less significant associations were found as compared with the primary intention-to-treat analyses for all treatment groups. CONCLUSION: There were no differences in overall cardiovascular risks among several add-on second-line oral antidiabetic agents; however, glinide plus metformin and α-glucosidase inhibitors plus metformin combination therapies might be associated with lower risks of acute myocardial infarction.

Omega-3 dietary Fatty Acid status of healthy older adults in Tasmania, Australia: an observational study.

OBJECTIVES: To determine the dietary and supplement intake of omega-3 (n-3) polyunsaturated fatty acids (PUFA) of older Tasmanian adults; their plasma n-3 PUFA status and the relationship between n-3 PUFA intake and plasma status. DESIGN: Cross-sectional study. SETTING: Launceston and surrounding regions, Tasmania, Australia. PARTICIPANTS: Seventy-three community-dwelling older adults: 23 men aged 70 ± 6.1 years and 50 women aged 70 ± 6.7 years. MEASUREMENTS: A validated, semi-quantitative food frequency questionnaire estimated dietary PUFA intake. The plasma phospholipid fraction of venous blood samples was analysed for fatty acid content. Anthropometric data was recorded. RESULTS: Thirty-five participants (48%) regularly ingested a fish oil supplement. Their plasma n-3 PUFA profile contained significantly more eicosapentaenoic acid (EPA) (odds ratio 3.14; 95% CI 1.37% to 7.30%; p<0.05) and docosahexaenoic acid (DHA) (odds ratio 2.64; 95% CI 1.16% to 6.01%; p<0.05) than non-supplement users. Fish and meat were the main dietary sources of n-3 PUFAs. Participants most commonly consumed fish 3-4 times per week. Significant associations of dietary α-linolenic acid (ALA), EPA, docosapentaenoic acid (DPA) and DHA with plasma n-3 PUFAs were noted but not always between dietary and plasma counterparts. CONCLUSION: Without the use of fish oil supplements, most study participants were unable to meet the recommended daily intake of 0.5g EPA and DHA combined; however, the plasma n-3 PUFA profile of non-supplement-users was still robust compared to other Australian and overseas studies.
