Additive effect of factors related to assisted conception on the reduction of maternal serum pregnancy-associated plasma protein A concentrations and…
2013
Objective To analyze whether assisted conceptions need adjustments in first-trimester Down syndrome screening and why modifications in screening markers occur. Design Eleven-year cohort retrospective analysis. Setting Maternal-fetal medicine unit. Patient(s) Two thousand eleven naturally conceived normal singleton pregnancies and 2,042 normal singleton pregnancies achieved with assisted conception: 350 by IUI and 1,692 with IVF (n = 328) or intracytoplasmic sperm injection (ICSI; n=1,364), using nondonor (n = 1,086) or donated ova (n = 606), with fresh (n = 1,432) or frozen (n = 260) embryos. Intervention(s) Comparison of ultrasound and biochemical markers of first-trimester Down syndrome s…
Risk Weighing in Twin Pregnancy
2010
Multiple pregnancies are more often associated with complications than singleton pregnancies. In our retrospective study of 613 twin pregnancies the most important risk factors in twin pregnancies were premature labour before the 37th week of gestation and the premature rupture of the membrane. The increase of perinatal mortality and morbidity for twins might be primary the result of premature delivery.
Impact of donor-recipient age on cardiac transplant survival. Subanalysis of the Spanish Heart Transplant Registry.
2020
[Abstract] Introduction and objectives. The age of heart transplant recipients and donors is progressively increasing. It is likely that not all donor-recipient age combinations have the same impact on mortality. The objective of this work was to compare survival in transplant recipients according to donor-recipient age combinations. Methods. We performed a retrospective analysis of transplants performed between 1 January 1993 and 31 December 2017 in the Spanish Heart Transplant Registry. Pediatric transplants, retransplants and combined transplants were excluded (6505 transplants included). Four groups were considered: a) donor < 50 years for recipient < 65 years; b) donor < 50 years for r…
REVIEW OF RETROSPECTIVE DOSIMETRY TECHNIQUES FOR EXTERNAL IONISING RADIATION EXPOSURES
2011
The current focus on networking and mutual assistance in the management of radiation accidents or incidents has demonstrated the importance of a joined-up approach in physical and biological dosimetry. To this end, the European Radiation Dosimetry Working Group 10 on 'Retrospective Dosimetry' has been set up by individuals from a wide range of disciplines across Europe. Here, established and emerging dosimetry methods are reviewed, which can be used immediately and retrospectively following external ionising radiation exposure. Endpoints and assays include dicentrics, translocations, premature chromosome condensation, micronuclei, somatic mutations, gene expression, electron paramagnetic re…
Primary thromboembolic prevention in multiple myeloma patients: An exploratory meta-analysis on aspirin use
2018
Background: Multiple myeloma (MM) is a common hematological disorder, often complicated by venous thromboembolism, especially during treatment with immunomodulatory drugs. Acetylsalicylic acid (ASA) has been extensively used as thromboprophylaxis but its rationale is unclear and the efficacy versus low-molecular weight heparins (LMWH) is still matter of debate. European and American guidelines suggest different approaches and the optimal antithrombotic strategy is yet to be established. Methods: We conducted an exploratory metanalysis and a systematic review on studies comparing ASA versus other interventions for thromboprophylaxis (no intervention or LMWH) in patients with MM. Results: Ten…
Effects of the number of removed lymph nodes on survival outcome in patients with sentinel node-negative breast cancer.
2021
Abstract Background Sentinel lymph node biopsy is the gold standard surgical technique for axillary staging in patients with clinically node-negative. However, it is still uncertain what is the optimal number of sentinel lymph nodes (SLNs) to be removed to reduce the false-negative rate. The aim of this study was to investigate whether patients with a single negative SLN have a worse prognosis than those with two or more negative SLNs. Methods A retrospective review was conducted on a large series of SLN-negative breast cancer patients. Survival outcomes and regional recurrence rate were evaluated according to the number of removed SLNs. Secondly, the contribution of different adjuvant ther…
Patterns of care and cost profiles of women with breast cancer in Italy: EPICOST study based on real world data
2020
Objectives To estimate total direct health care costs associated to diagnosis and treatment of women with breast cancer in Italy, and to investigate their distribution by service type according to the disease pathway and patient characteristics. Methods Data on patients provided by population-based Cancer Registries are linked at individual level with data on health-care services and corresponding claims from administrative databases. A combination of cross-sectional approach and a threephase of care decomposition model with initial, continuing and final phases-of-care defined according to time occurred since diagnosis and disease outcome is adopted. Direct estimation of cancer-related cost…
Accuracy of SCORTEN and ABCD‐10 to predict mortality and the influence of renal function in Stevens–Johnson syndrome/toxic epidermal necrolysis
2020
Epidermal necrolysis (EN) compromises a spectrum of life-threatening dermatoses (Stevens-Johnson Syndrome [SJS], overlap syndrome and toxic epidermal necrolysis [TEN]). Currently, no active therapeutic regimen with unequivocal benefit exists for SJS/TEN. SCORTEN is the widely-used prognostic scale specific for SJS/TEN. Nevertheless, a new prognostic scale, the ABCD-10, has been recently proposed. In this context, acute renal failure (ARF) seems to be an important comorbidity that could influence prognosis in SJS/TEN patients more than it is assumed by these two scales. Our objectives were to compare the accuracy of the SCORTEN and ABCD-10 scales in predicting the mortality in SJS/TEN, and t…
Acute kidney injury in heart failure: a population study
2020
Abstract Aims The objective of the present study is to assess the prognostic value of acute kidney injury (AKI) in the evolution of patients with heart failure (HF) using real‐world data. Methods and results Patients with a diagnosis of HF and with serial measurements of renal function collected throughout the study period were included. Estimated glomerular filtration rate (GFR) was calculated with the CKD‐EPI (Chronic Kidney Disease Epidemiology Collaboration). AKI was defined when a sudden drop in creatinine with posterior recovery was recorded. According to the Risk, Injury, Failure, Loss, and End‐Stage Renal Disease (RIFLE) scale, AKI severity was graded in three categories: risk [1.5‐…
Repeated resection for recurrent intrahepatic cholangiocarcinoma: A retrospective German multicentre study.
2020
Background Tumour recurrence is common after resection of intrahepatic cholangiocarcinoma (ICC). Repeated resection is a potential curative treatment, but outcomes are not well-defined thus far. The aim of this retrospective multicentre cohort study was to show the feasibility and survival of repeated resection of ICC recurrence. Methods Data were collected from 18 German hepato-pancreatico-biliary centres for patients who underwent repeated exploration of recurrent ICC between January 2008 and December 2017. Primary end points were overall (OS) and recurrence-free survival from the day of primary and repeated resection. Results Of 156 patients who underwent repeated exploration for recurre…
