Short- and long-term outcomes for the surgical treatment of acute pulmonary embolism
2018
AbstractObjectivesAcute pulmonary embolism can be a life-threatening condition with a high mortality. The treatment choice is a matter of debate. The early and late outcomes of patients treated with surgical pulmonary embolectomy for acute pulmonary embolism in a single center were analyzed.MethodsAll consecutive patients operated on for pulmonary embolism between January 2002 and March 2017 were reviewed. Patient demographics and pre- and postoperative clinical data were retrieved from our patient registry, and risk factors for in-hospital and long-term mortality were identified.ResultsIn total, 175 patients (mean age 59±3 years, 50% male) were operated on for acute pulmonary embolism. In-…
Time trends of benign/malignant breast biopsy ratios a multicenter Italian study.
1996
Aims and background Although they have been decreasing over time due to improved specificity of diagnostic assessment, benign biopsies of the breast are still common. Benign biopsies should be regarded as negative events, due to their economical and psychological cost and their possible negative impact on cosmesis and on further diagnostic evaluation. Methods Retrospective data on benign/malignant breast biopsies ratio (B/M) were collected in 9 Italian centers for a period of 10-15 years. The time trend of B/M and its association to age or to single centers was evaluated. Results Overall 31,001 cases were considered. A strong association of B/M to age was evident (average B/M values were 5.…
Late Breaking Abstract - Relationship between clinical features and mortality in a cohort of COPD patients
2021
Background: Chronic obstructive pulmonary disease (COPD) is a progressive disease with poor outcomes, including a high mortality. GULP is a multicenter Italian study that described clinical characteristics, exacerbation rates and survival of a cohort of COPD patients, as part of AstraZeneca’s AvoidEX program. Aims and objectives: To evaluate whether the clinical profile of subjects enrolled in the GULP study predicts mortality on a period of 3 years. Methods: Post-hoc analysis of an observational, multicenter, retrospective study. Patients were stratified according to survival status: alive (A) and dead (D). Clinical characteristics, comorbidities and exacerbation rates were reported in the…
Risk factors associated with adverse fetal outcomes in pregnancies affected by Coronavirus disease 2019 (COVID-19): a secondary analysis of the WAPM …
2020
Abstract Objectives To evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19. Methods Secondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. The primary outcome was a composite adverse fetal outcome, defined as the presence of either abortion (pre…
X Chromosome Contribution to the Genetic Architecture of Primary Biliary Cholangitis
2021
Background & aims: Genome-wide association studies in primary biliary cholangitis (PBC) have failed to find X chromosome (chrX) variants associated with the disease. Here, we specifically explore the chrX contribution to PBC, a sexually dimorphic complex autoimmune disease. Methods: We performed a chrX-wide association study, including genotype data from 5 genome-wide association studies (from Italy, United Kingdom, Canada, China, and Japan; 5244 case patients and 11,875 control individuals). Results: Single-marker association analyses found approximately 100 loci displaying P < 5 × 10-4, with the most significant being a signal within the OTUD5 gene (rs3027490; P = 4.80 × 10-6; odds…
Calorie intake, olive oil consumption and mammographic density among Spanish women
2013
High mammographic density (MD) is one of the main risk factors for development of breast cancer. To date, however, relatively few studies have evaluated the association between MD and diet. In this cross-sectional study, we assessed the association between MD (measured using Boyd's semiquantitative scale with five categories: 75%) and diet (measured using a food frequency questionnaire validated in a Spanish population) among 3,548 peri- and postmenopausal women drawn from seven breast cancer screening programs in Spain. Multivariate ordinal logistic regression models, adjusted for age, body mass index (BMI), energy intake and protein consumption as well as other confounders, showed an asso…
Viral infection, atopy and mycosis fungoides
2003
Mycosis fungoides (MF) is a rare disease with an unknown aetiology, although it has been suggested that infections may play a role. The present study investigates whether infections, atopic disorders and some other diseases are risk indicators for MF. A European multicentre case-control study involving seven rare cancers, including MF, was conducted from 1995 to 1998. Patients between 35 and 69 years of age diagnosed with MF (n = 140) were recruited, and the diagnoses were verified by a reference pathologist, who classified 83 cases as definitive and 35 cases as possible; 22 cases were not accepted. Of the 118 accepted cases, 104 patients were interviewed (including 76 definitive cases and …
Fetal growth and childhood acute lymphoblastic leukemia: Findings from the childhood leukemia international consortium
2013
Positive associations have been reported between measures of accelerated fetal growth and risk of childhood acute lymphoblastic leukemia (ALL). We investigated this association by pooling individual-level data from 12 case-control studies participating in the Childhood Leukemia International Consortium. Two measures of fetal growth – weight-for-gestational-age and proportion of optimal birth weight (POBW) – were analysed. Study-specific odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using multivariable logistic regression, and combined in fixed effects meta-analyses. Pooled analyses of all data were also undertaken using multivariable logistic regression. Subgroup analy…
Home pesticide exposures and risk of childhood leukemia: Findings from the childhood leukemia international consortium
2015
Some previous studies have suggested that home pesticide exposure before birth and during a child's early years may increase the risk of childhood leukemia. To further investigate this, we pooled individual level data from 12 case-control studies in the Childhood Leukemia International Consortium. Exposure data were harmonized into compatible formats. Pooled analyses were undertaken using multivariable unconditional logistic regression. The odds ratio (ORs) for acute lymphoblastic leukemia (ALL) associated with any pesticide exposure shortly before conception, during pregnancy and after birth were 1.39 (95% confidence interval [CI]: 1.25, 1.55) (using 2,785 cases and 3,635 controls), 1.43 (…
Relation of childhood brain tumors to exposure of parents and children to tobacco smoke: The Search international case-control study
2002
The etiology of childhood brain tumors (CBTs) remains unknown. Tobacco smoke contains several known carcinogens and can induce DNA adducts in human placenta and hemoglobin adducts in fetuses. We present the results of an international case-control study to evaluate the association between CBTs and exposure of parents and children to cigarette smoke. The study was undertaken as part of the SEARCH program of the IARC. Nine centers in 7 countries were involved. The studies mainly covered the 1980s and early 1990s. Cases (1,218, ages 0-19 years) were children newly diagnosed with a primary brain tumor; there were 2,223 population-based controls. Most mothers who agreed to participate were inter…
