To analyse the clinical features, laboratory data and foetal-maternal outcomes, and follow them up on a cohort of 1000 women with obstetric antiphospholipid syndrome (OAPS). Methods: The European Registry of OAPS became a registry within the framework of the European Forum on Antiphospholipid Antibody projects and was placed on a website in June 2010.

Background/Aim: Paraneoplastic syndrome symptoms include isolated involuntary weight loss (IIWL). The differential diagnosis of cancer from other diseases may require a significant number of tests. Tumour markers (TMs) can be used for the diagnosis and stratification of patients according to cancer risk. Patients and Methods: This study included 606 patients (48% females) seen at the rapid diagnostic unit for IIWL. We determined the levels of TMs carcinoembryonic antigen, carbohydrate antigen 19-9, soluble fragments of cytokeratin 19, carbohydrate antigen 15-3, carbohydrate antigen 125, neuron specific enolase, alpha-fetoprotein, prostatic specific antigen using the multiparametric analyser COBAS 601. Two cut-off points were established, the upper reference limit described by the manufacturer and a high cut-off point suggested by Molina et al., to stratify patients according to cancer risk. Results: Patients were classified according to TM levels as follows: I) all TMs below the upper reference limit; II) highest number of TMs between the two cut-offs; III) at least one TM above the higher cut-off. The odds ratio for malignancy was 4.3 for group II and 248 for group III. These results indicate that when at least one TM is above the higher cut-off, neoplasia is highly probable. Conclusion: TM determination allowed to establish cancer risk in patients with IIWL.Many cancer patients do not present specific symptoms or signs when they consult medical services (1, 2). These symptoms, including cachexia, weight loss, and muscle wasting arise from tumour secretion of hormones, peptides or cytokines (3,4) or in case of autoimmune neurological disorders, from immune cross reactivity between malignant and normal host tissues (5,6). Other disorders are due to tumour invasion or compression in surrounding or distant tissues.In some cases, paraneoplastic syndromes are presented before cancer diagnosis and may be used to select patients for more exhaustive tests, in order to perform differential diagnosis with benign diseases.In our country, specialised hospital units have been created to avoid unnecessary delays for patients with these symptoms. The rapid diagnostic unit (RDU) is an ambulatory resource for the study of severe pathologies without the need for hospital admission. It refers to patients with guidesymptoms derived from other hospital services or primary care. Some of the frequent signs that require referral to RDU are constitutional syndrome, wasting syndrome, or isolated involuntary weight loss (IIWL). Between 10 and 30% of patients who arrive at these units present involuntary weight loss as the only sign. In the RDU, they are being prioritized to undergo endoscopies, image tests, blood tests and biopsies in order to reach a diagnosis and start treatment when possible within one month (7-9).

Background Goal-directed haemodynamic therapy (GDHT) has been shown to reduce morbidity and mortality in high-risk surgical patients. However, there is little evidence of its efficacy in patients undergoing hip fracture surgery. This study aims to evaluate the effect of GDHT guided by non-invasive haemodynamic monitoring on perioperative complications in patients undergoing hip fracture surgery. Methods Patients > 64 years undergoing hip fracture surgery within an enhanced recovery pathway (ERP) were enrolled in this single-centre, non-randomized, intervention study with a historical control group and 12-month follow-up. Exclusion criteria were patients with pathological fractures, traffic-related fractures and refractures. Control group (CG) patients received standard care treatment. Intervention group (IG) patients received a GDHT protocol based on achieving an optimal stroke volume, in addition to a systolic blood pressure > 90 mmHg and an individualized cardiac index. No changes were made between groups in the ERP during the study period. Primary outcome was percentage of patients who developed intraoperative haemodynamic instability. Secondary outcomes were intraoperative arrhythmias, postoperative complications (cardiovascular, respiratory, infectious and renal complications), administered fluids, vasopressor requirements, perioperative transfusion, length of hospital stay, readmission and 1-year survival. Results In total, 551 patients (CG=272; IG=279) were included. Intraoperative haemodynamic instability was lower in the IG (37.5% vs 28.0%; p=0.017). GDHT patients had fewer postoperative cardiovascular (18.8% vs 7.2%; p < 0.001), respiratory (15.1% vs 3.6%; p<0.001) and infectious complications (21% vs 3.9%; p<0.001) but not renal (12.1% vs 33.7%; p<0.001). IG patients had less vasopressor requirements (25.5% vs 39.7%; p<0.001) and received less fluids [2.600 ml (IQR 1700 to 2700) vs 850 ml (IQR 750 to 1050); p=0.001] than control group. Fewer patients required transfusion in GDHT group (73.5% vs 44.4%; p<0.001). For IG patients, median length of hospital stay was shorter [11 days (IQR 8 to 16) vs 8 days; (IQR 6 to 11) p < 0.001] and 1-year survival higher [73.4% (95%CI 67.7 to 78.3 vs 83.8% (95%CI 78.8 to 87.7) p<0.003]. Conclusions The use of GDHT decreases intraoperative complications and postoperative cardiovascular, respiratory and infectious but not postoperative renal complications. This strategy was associated with a shorter hospital stay and increased 1-year survival. Trial registration ClinicalTrials.gov NCT02479321.
