The management of acute venous thromboembolism in clinical practice. Results from the European PREFER in VTE Registry
Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in Europe. Data from real-world registries are necessary, as clinical trials do not represent the full spectrum of VTE patients seen in clinical practice. We aimed to document the epidemiology, management and outcomes of VTE using data from a large, observational database. PREFER in VTE was an international, non-interventional disease registry conducted between January 2013 and July 2015 in primary and secondary care across seven European countries. Consecutive patients with acute VTE were documented and followed up over 12 months. PREFER in VTE included 3,455 patients with a mean age of 60.8 ± 17.0 years. Overall, 53.0 % were male. The majority of patients were assessed in the hospital setting as inpatients or outpatients (78.5 %). The diagnosis was deep-vein thrombosis (DVT) in 59.5 % and pulmonary embolism (PE) in 40.5 %. The most common comorbidities were the various types of cardiovascular disease (excluding hypertension; 45.5 %), hypertension (42.3 %) and dyslipidaemia (21.1 %). Following the index VTE, a large proportion of patients received initial therapy with heparin (73.2 %), almost half received a vitamin K antagonist (48.7 %) and nearly a quarter received a DOAC (24.5 %). Almost a quarter of all presentations were for recurrent VTE, with >80 % of previous episodes having occurred more than 12 months prior to baseline. In conclusion, PREFER in VTE has provided contemporary insights into VTE patients and their real-world management, including their baseline characteristics, risk factors, disease history, symptoms and signs, initial therapy and outcomes

Evaluation of appendicitis risk prediction models in adults with suspected appendicitis
Background
Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis.
Methods
A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16–45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (proportion of patients who did not have appendicitis correctly classified as low risk) whilst maintaining a failure rate below 5 per cent (proportion of patients identified as low risk who actually had appendicitis).
Results
Some 5345 patients across 154 UK hospitals were identified, of which two‐thirds (3613 of 5345, 67·6 per cent) were women. Women were more than twice as likely to undergo surgery with removal of a histologically normal appendix (272 of 964, 28·2 per cent) than men (120 of 993, 12·1 per cent) (relative risk 2·33, 95 per cent c.i. 1·92 to 2·84; P < 0·001). Of 15 validated risk prediction models, the Adult Appendicitis Score performed best (cut‐off score 8 or less, specificity 63·1 per cent, failure rate 3·7 per cent). The Appendicitis Inflammatory Response Score performed best for men (cut‐off score 2 or less, specificity 24·7 per cent, failure rate 2·4 per cent).
Conclusion
Women in the UK had a disproportionate risk of admission without surgical intervention and had high rates of normal appendicectomy. Risk prediction models to support shared decision‐making by identifying adults in the UK at low risk of appendicitis were identified

Cysteine and serine proteases in gastric cancer
I.F. 2.864
Abstract: Background. Cysteine proteases (cathepsin B [CATB] and cathepsin L [CATL]), the serine protease urokinase-type plasminogen activator (UPA), and plasminogen activator inhibitor type-1 (PAI-1) are thought to play an important part in cancer invasion and metastasis. The aims of this study were to measure CATB, CATL, UPA, and PAI-1 in gastric cancer (GC) and normal mucosa distant from the tumor (NORM); to evaluate whether tissue levels are related to tumor stage, grade, or histotype; to assess their prognostic relevance; and to examine UPA and PAI-1 expression immunohistochemically.
Methods. Gastric cancer and NORM samples were obtained from 25 patients with gastric cancer patients undergoing surgery (17 males, 8 females; mean age, 62 years; range, 31-84 years). Antigen concentrations were measured using the enzyme-linked immunosorbent assay method. Immunohistochemistry was performed using monoclonal UPA and PAI-1 antibodies.
Results. Significantly higher antigen levels were found: (1) in GC vs. NORM (CATB, CATL, UPA, PAI-1) tissues; (2) in GC with versus without metastasis (CATB, CATL, UPA); (3) in poorly or moderately versus well differentiated GC; and (4) in diffuse versus intestinal-type GC (CATB, CATL). Urokinase-type plasminogen activator, PAI-1 and CATB levels had a significant prognostic impact. Cancer and stromal cells, showed immunoreactivity to anti-UPA and anti-PAI-1 antibodies.
Conclusions. These results confirm the important role of CATB, CATL, UPA and PAI-1 in gastric cancer progression. Higher levels are detected in GC with metastases, poorer differentiation, and diffuse histotype, thus identifying patients with a worse prognosis

Do Perioperative Blood Transfusions Influence Prognosis of Gastric Cancer Patients? Analysis of 927 Patients and Interactions with Splenectomy
IF 3,898
This study was to assess the influence of perioperative blood transfusions on the prognosis of patients undergoing a potentially curative resection for gastric cancer and to investigate the interaction between transfusions and splenectomy.
Between January 1990 and December 2005, 927 patients from 6 Italian tertiary referral centers underwent curative resections for gastric cancer. Clinical and pathologic variables were prospectively collected. The influence of perioperative blood transfusions on survival were evaluated by univariate and multivariate analysis. Moreover, the influence of splenectomy both in transfused and nontransfused patients undergoing total gastrectomy was also evaluated.
The overall 5-year survival was 54.6%. The 5-year survival rate in transfused patients (n = 327) was 50.6% compared with 56.6% in nontransfused patients (n = 600) (P = .094). In the subgroup of patients who underwent total gastrectomy with spleen preservation (n = 209), 5-year survival rate was 46% and 51.4% in transfused and nontransfused patients, respectively (P = .418); those who underwent total gastrectomy with splenectomy (n = 199) presented a 5-year survival rate of 45% in transfused group compared with 39.1% in nontransfused patients (P = .571).
Our study indicates a slightly, but not significantly, negative effect of allogeneic blood transfusion on prognosis of gastric cancer patients. In the subgroup of patients who underwent total gastrectomy, splenectomy seems to invert this mild effect, with a positive influence on overall surviva
