Short-term economic impact of the Zika virus outbreak

Summary Zika virus (ZIKV) is mainly transmitted by mosquitoes bites. However, transmission by sexual contacts has been reported in 11 non endemic countries. The rapid spread of ZIKV in Latin American and Caribbean Countries (LCR), person-to-person transmission and perceived risk on people’s well being can affect the emerging economies of LCR which historically dependent on truism. Here we present an analysis on economic outputs for assessing the current impact of ZIKV on markets. Our analysis show an unexpected resilience of LCR markets to international alerts. This positive response represents an opportunity to scale-up interventions for preventing the further spreading of the ZIKV epidemic

Gender differences in asthma perception and its impact on quality of life: A post hoc analysis of the PROXIMA (Patient Reported Outcomes and Xolair\uae in the Management of Asthma) study

Background: Gender differences in asthma perception and control have been reported. The PROXIMA observational study assessed these outcomes in a cohort of Italian severe allergic asthma (SAA) patients. This post hoc analysis of the PROXIMA results was aimed at assessing gender differences in SAA in a real-world setting, focusing on disease perception and impact on quality of life (QoL). Methods: The PROXIMA study was an observational, multicenter study, consisting of a cross-sectional and a prospective longitudinal phase, including adult outpatients diagnosed with SAA at step 4 requiring a therapeutic step-up. Patients on omalizumab treatment at baseline were included in the 12-month longitudinal phase. Disease control was assessed by the Asthma Control Questionnaire (ACQ) score, patients' disease perception by the Brief Illness Perception Questionnaire (BIPQ), and QoL by the EuroQoL five-dimensional three-level questionnaire (EQ-5D-3 L) at baseline and after 6 and 12 months. Two regression models were used to evaluate the association between gender and BIPQ total score and EQ-5D-3L score, respectively. Results: 357 patients (65% females) were analyzed for the cross-sectional phase and 99 (62.6% females) for the longitudinal phase. The prevalence of perennial and seasonal aeroallergens was similar between genders. ACQ score decreased similarly during omalizumab treatment at 6 and 12 months in both genders; no gender differences were observed in control rates. Asthma perception was worse among females at all study visits reaching statistical significance at 12 months (mean (SD) B-IPQ total score 41.8 (9.4) vs 35.6 (12.0); T test p-value (males vs females) < 0.05). Statistically significant gender differences were observed for some specific items, with males reporting less symptom experience, concern about the disease, and emotional impact at 12-months. The results of the multivariate regression model for repeated measures showed that overall treatment with omalizumab improved disease perception overtime regardless from gender. Males reported a significantly better QoL compared to females at both 6 and 12 months. Conclusions: In this real-world setting, females confirmed to have a worse perception of asthma, feel it as more symptomatic and suffer a greater impact on their QoL, even though having similar baseline severity and obtaining similar level of control

Metabolic changes in concussed American football players during the acute and chronic post-injury phases

<p>Abstract</p> <p>Background</p> <p>Despite negative neuroimaging findings many athletes display neurophysiological alterations and post-concussion symptoms that may be attributable to neurometabolic alterations.</p> <p>Methods</p> <p>The present study investigated the effects of sports concussion on brain metabolism using ¹H-MR Spectroscopy by comparing a group of 10 non-concussed athletes with a group of 10 concussed athletes of the same age (mean: 22.5 years) and education (mean: 16 years) within both the acute and chronic post-injury phases. All athletes were scanned 1-6 days post-concussion and again 6-months later in a 3T Siemens MRI.</p> <p>Results</p> <p>Concussed athletes demonstrated neurometabolic impairment in prefrontal and motor (M1) cortices in the acute phase where NAA:Cr levels remained depressed relative to controls. There was some recovery observed in the chronic phase where Glu:Cr levels returned to those of control athletes; however, there was a pathological increase of m-I:Cr levels in M1 that was only present in the chronic phase.</p> <p>Conclusions</p> <p>These results confirm cortical neurometabolic changes in the acute post-concussion phase as well as recovery and continued metabolic abnormalities in the chronic phase. The results indicate that complex pathophysiological processes differ depending on the post-injury phase and the neurometabolite in question.</p

Pathogen reduction/inactivation of products for the treatment of bleeding disorders:what are the processes and what should we say to patients?

Patients with blood disorders (including leukaemia, platelet function disorders and coagulation factor deficiencies) or acute bleeding receive blood-derived products, such as red blood cells, platelet concentrates and plasma-derived products. Although the risk of pathogen contamination of blood products has fallen considerably over the past three decades, contamination is still a topic of concern. In order to counsel patients and obtain informed consent before transfusion, physicians are required to keep up to date with current knowledge on residual risk of pathogen transmission and methods of pathogen removal/inactivation. Here, we describe pathogens relevant to transfusion of blood products and discuss contemporary pathogen removal/inactivation procedures, as well as the potential risks associated with these products: the risk of contamination by infectious agents varies according to blood product/region, and there is a fine line between adequate inactivation and functional impairment of the product. The cost implications of implementing pathogen inactivation technology are also considered

Investor Horizon and Disclosure Policies

We investigate the relation between investor horizon and disclosure policy. We develop and analyze a rational expectations model where the original investors commit to a disclosure policy. Counter to casual intuition, short-horizon investors prefer more disclosure and are willing to bear costs of disclosure to reduce information asymmetries among capital market participants. We empirically test our predictions in the setting of newly public firms and find that firms with short-horizon controlling investors disclose more than other firms and experience lower information asymmetry. Our study contributes to the understanding of firms' disclosure choices by suggesting that the horizon of controlling investors shapes a firm's disclosure polic

CEO turnover, earnings management and value relevance. A theoretical analysis on the Italian context

The aim of this paper is to provide a theoretical framework in order to study the relationship between earnings management and CEO turnover in Italy. The issue is relevant because it has never been tackled in the Italian context, which presents some important peculiarities when compared to other, most widely studied, corporate governance systems. We find that, according to previous literature and despite the relevant differences existing between market oriented and control-oriented systems, there should be a positive relationship between the level of earnings management and the likelihood for CEOs to be turnovered. Relying on the literature on value relevance, we also analyze the relation between CEO turnover and value relevance of earnings, which in this context is seen as a consequence of the turnover. We propose that the market may reward the company for its decision of contrasting earnings management by firing the CEO through increasing the 'weight' attributed to its accounting numbers

Dalla CSR alla social innovation

La responsabilità sociale d’impresa (RSI) rappresenta un tema di grande interesse e discussione, sia per le imprese che per gli studiosi. Il dibattito si svolge soprattutto nel comprendere in che modo lo strumento possa essere migliorato e reso più efficace. Rispetto a questo tema, la comunità scientifica cerca di comprendere quali sono gli sviluppi futuri della RSI. Il tema dell’Innovazione Sociale si inserisce proprio all’interno di questo dibattito, rappresentando una opportunità per la RSI di evolvere in qualcosa di nuovo. In questo articolo si cerca di sistematizzare quali sono i punti di interconnessione tra RSI e Innovazione Sociale in maniera tale da sviluppare una piattaforma di lavoro congiunt
