Determinants of Individual Investment Decisions in Investment-Based Crowdfunding
2017
We investigate determinants of investment decisions in investment-based (equity and real estate) crowdfunding, using a novel investment-, investor- and campaign-level database. We find that this market is a man's world, with nearly 93% of investments made by men. Consistent with behavioral and finance theories, we find that women invest less in the riskiest investments but more in safer ones. Further analyses show that these findings are better explained by differences in risk aversion than differences in overconfidence between men and women. Investors located in an area considered more "sociable" (socially friendly) also invest more, but only if the investor is a woman. Overall, the findin…
Paracetamol and antibiotics in childhood and subsequent development of wheezing/asthma: association or causation?
2011
Background Several studies found an association between early administration of paracetamol and antibiotics and development of wheezing. This could be due to confounding: wheeze and asthmatic symptoms in early childhood are difficult to distinguish from respiratory tract infections that are widely treated with these drugs; in case of persistence of symptoms up to school age, this could explain the observed relationship. Methods We investigated the association between paracetamol and antibiotics use in the first year of life and wheezing phenotypes, i.e. wheezing starting in different time periods (early, persistent and late-onset) in the SIDRIA-2 study, a cross-sectional survey of 16,933 ch…
Telomere Length and Frailty: The Helsinki Birth Cohort Study
2018
Objectives: Telomere length is associated with aging-related pathologies. Although the association between telomere length and frailty has been studied previously, only a few studies assessing longitudinal changes in telomere length and frailty exist. Design: Longitudinal cohort study. Setting and participants: A subpopulation of the Helsinki Birth Cohort Study consisting of 1078 older adults aged 67 to 79 years born in Helsinki, Finland, between 1934 and 1944. Measures: Relative leukocyte telomere length (LTL) was measured using quantitative real-time polymerase chain reaction at the average ages of 61 and 71 years, and at the latter the participants were assessed for frailty according to …
Knee arthroscopy and exercise versus exercise only for chronic patellofemoral pain syndrome: a randomized controlled trial.
2007
Abstract Background Arthroscopy is often used to treat patients with chronic patellofemoral pain syndrome (PFPS). As there is a lack of evidence, we conducted a randomized controlled trial to study the efficacy of arthroscopy in patients with chronic PFPS. Methods A total of 56 patients with chronic PFPS were randomized into two treatment groups: an arthroscopy group (N = 28), treated with knee arthroscopy and an 8-week home exercise program, and a control group (N = 28), treated with the 8-week home exercise program only. The arthroscopy included finding-specific surgical procedures according to current recommendations. The primary outcome was the Kujala score on patellofemoral pain and fu…
First-trimester screening for trisomy-21 using a simplified method to assess the presence or absence of the fetal nasal bone.
2005
Objective To determine the benefit of including nasal bone assessment in addition to standard first-trimester markers (nuchal translucency, free beta human chorionic gonadotropin and pregnancy-associated plasma protein A) as a screening test for Down syndrome, using a strict criterion for classification of nasal bone absence. Study design Nasal bone assessment was conducted in 2411 patients with crown-rump length between 45 and 84 mm, including 15 patients with Down syndrome. A patient was considered to have an absent nasal bone only if there was no evidence of present nasal bone. Unlike other studies, nasal bone was classified as present when there was evidence of a thin echogenic line und…
Anakinra drug retention rate and predictive factors of long-term response in systemic juvenile idiopathic arthritis and adult onset still disease
2019
Background and Objective: Only a few studies have reported long-term efficacy of interleukin (IL)-1 inhibition in systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still disease (AOSD). Herein we report on the effectiveness of anakinra (ANA), expressed in terms of drug retention rate (DRR), and evaluate the predictive factors of drug survival in a cohort of patients with sJIA and AOSD. Patients and Methods: This is a multicenter study reviewing retrospectively the medical records from 61 patients with sJIA and 76 with AOSD, all treated with ANA in 25 Italian tertiary referral centers. Results: The cumulative retention rate of ANA at 12-, 24-, 48-, and 60-month of follow-up was 7…
Blood pressure for outcome prediction and risk stratification in acute pulmonary embolism.
2015
Abstract Introduction Risk stratification of patients with acute pulmonary embolism (PE) is crucial in deciding appropriate therapy management. Blood pressure (BP) is rapidly available and a reliable parameter. We aimed to investigate BP for short-term outcome in acute PE. Materials and methods Data of 182 patients with acute PE were analyzed retrospectively. Logistic regression models were calculated to investigate associations between BP and in-hospital-death as well as myocardial necrosis. Moreover, receiver operating characteristic (ROC) curves and cutoff values for systolic and diastolic BPs predicting in-hospital death and myocardial necrosis were computed. Results A total of 182 pati…
Immune-unreactive urinary albumin as a predictor of cardiovascular events: The Hortega Study
2019
Background: We aimed to determine if immune-unreactive albumin excretion (IURAE) is associated with cardiovascular (CV) events in a representative sample of a general population from Spain.Methods: We included 1297 subjects (mean age ± standard error 48.0 ± 0.2 years, 48% females), who participated in the Hortega Follow-Up Study. The primary endpoint was incidence of fatal and non-fatal CV events. Urinary albumin excretion (UAE) was measured in spot voided urine, frozen at -80°C, by immunonephelometry [immune-reactive albumin excretion (IRAE)] and by high-performance liquid chromatography (HPLC) [total albumin excretion (AE)]. IURAE was calculated as the difference between HPLC measurements…
Impact of routine invasive strategy on outcomes in patients with non-ST-segment elevation myocardial infarction during 2005–2014: A report from the P…
2020
Background: Non-ST-segment elevation myocardial infarction (NSTEMI) has become the most frequently encountered type of myocardial infarction. The patient clinical profile and management has evolved over the past decade. As there is still a scarcity of data on the latest trends in NSTEMI, changes herein were observed and assessed in the treatment and outcomes in Poland between 2005 and 2014. Methods: A total of 197,192 patients with NSTEMI who enrolled in the Polish Registry of Acute Coronary Syndromes (PL-ACS) between 2005 and 2014 were analyzed. In-hospital and 12-month mortality were assessed. Results: Coronary angiography use increased from 35.8% in 2005–2007 to 90.7% in 2012–2014 (p < 0…
Early deaths from childhood cancer in Germany 1980-2016
2020
Abstract Background Even though the survival of childhood cancer has improved over the last decades, there are still children dying shortly after diagnosis. The aim of the study is to add to understanding of the reasons for deaths shortly after date of diagnosis. Methods Using data of the population-based German Childhood Cancer Registry (cancer below 15 years of age diagnosed between 1980 and 2016), we compared characteristics of 671 children with cancer who died within 30 days of diagnosis to 53,649 patients with childhood cancer who survived longer. In addition to a descriptive analysis, we used logistic regression with multivariable fractional polynomials to describe the relationship be…
