Screening for Infectious diseases among newly arrived migrants. experiences and practices in non-EU countries of the Mediterranean basin and Black Sea
Changing migration dynamics in the Mediterranean Sea and differences in infectious diseases (ID) burden between the countries of origin have raised questions whether public health actions are needed to avoid the transmission of ID. Screening newly arrived migrants for ID is one health monitoring option, offering opportunities for prevention, early detection and treatment. The authors conducted a survey among country experts in non-European Union countries of the Mediterranean and Black Sea, in order to explore current ID screening practices and policies for newly arrived migrants. The association between the existence of guidelines and the proportion of refugees in the population was also estimated. Eighteen country experts responded (90%) out of the 20 invited. Eleven countries (61%) implemented screening programmes and six (38%) had national guidelines. Screening was performed most often for tuberculosis at the holding level. A higher proportion of refugees in the population was associated with the existence of guidelines for screening (p = 0.05). Fourteen experts (88%) considered screening among migrants useful. The results show that screening for ID in newly arrived migrants is relevant for non-EU countries of the Mediterranean and Black Sea. Common guidelines could be promoted focusing on both individual and public health benefits of screening programmesChanging migration dynamics in the Mediterranean Sea and differences in infectious diseases (ID) burden between the countries of origin have raised questions whether public health actions are needed to avoid the transmission of ID.

Come affinare le armi della seduzione: emozioni e vigilanza epistemica
Seduction is often seen as a deceptive strategic game, which hampers deliberation. However, in case of seduction, emotions play a central role in modulating communicated contents. In this sense, seduction is not a form of deception, but an impulse to know. How to provide a cognitive account of seduction able to distinguish it from deception? Within philosophical Western tradition, emotions have a negative role in deliberation as they are automatic, unconscious and obliged. In contrast with this tradition, Mascaro and Sperber have recently argued that the capacity for epistemic vigilance enables people to filter misinformation, based not only on epistemic but also on affective knowledge. Some of the cognitive mechanisms presupposed by epistemic vigilance are targeted at the source of information, others at its content. Within the framework of the argumentative theory of reasoning, we propose a cognitive account of seduction able to distinguish it from deception, by focusing on the affective component of epistemic vigilance. We argue that in seduction emotions, far from being totally automatic, unconscious and obliged, contribute to the appreciation of both the source and content of information. Diversely from deception, seduction presupposes a positive role of emotions which induces a creative style of argumentation
Acquisitions of small high-tech firms as a mechanism for external knowledge sourcing: the integration-autonomy dilemma
Acquisitions of small high-tech firms by large incumbents are a prominent mechanism for external knowledge sourcing, whose success strictly depends on the choice of a wise post-acquisition implementation strategy. This paper theoretically discusses and empirically documents - on a sample of 458 deals in the 2001–2005 period - the antecedents of this choice by focusing on the integration-autonomy dilemma. Specifically, we jointly consider two main dimensions of the post-acquisition implementation: whether the acquiring firm absorbs the acquired one into its organization or keeps it separate as an autonomous subsidiary/business unit and whether the acquired CEO is replaced or retained. Separation with CEO retention corresponds to the minimum level of integration (and the maximum level of autonomy), whereas absorption with CEO replacement corresponds to the maximum level of integration (and the minimum level of autonomy.) We hypothesize that the acquiring firm chooses an implementation strategy with high level of integration when the acquired firm produces a component technology or operates in a related market. Indeed, in both cases, the interdependency between the two firms is high and thus the benefits of integration likely exceed the costs of the loss of autonomy. However, this positive association is weaker when the acquiring and acquired firms have common ground, originating from technological relatedness or prior alliances, which acts as a low-cost coordination mechanism. Results of econometric estimates largely confirm our hypotheses
The Use of Peripheral Blood-Mononuclear Cells in Scleroderma Patients: An Observational Preliminary Study
Introduction: Systemic sclerosis (SSc) is a systemic autoimmune
disease characterized by vasculopathy and excessive production
of collagen, which lead to skin and visceral fibrosis. The aim of our
study is to assess the potential benefits of autologous peripheral
blood mononuclear cells (PBMCs) implants in the treatment of clinical
manifestations such as mouth impairment, hand disability, digital ulcers
and Raynaud’s phenomenon in Scleroderma patients.
Methods: From February 2016 to May 2019, 10 female patients
were enrolled from the outpatient clinic of the Plastic Surgery Unit of
Sapienza University of Rome. Parameters evaluated were: patients’
disability, using the Health Assessment Questionnaire (HAQ) disability
index (DI) and the scleroderma HAQ (sHAQ); mouth opening capacity, by
measuring the maximum interincisal distance and the mouth perimeter;
hand mobility, assessed with clinical exam and the Hand Mobility in
Scleroderma (HAMIS) scale; Raynaud’s phenomenon, evaluated through
nailfold capillaroscopy; digital ulcers, examined through their features
and incidence of appearance. SPSS software was used for a simple
descriptive statistical analysis performed by the Student’s paired t-test.
P values less than 0.05 were considered statistically significant.
Results: The treatment showed a significant improvement of all
the parameters evaluated at 1-year follow-up, it was well-tolerated by
all the patients and the only complications noticed were small areas of
ecchymosis.
Conclusions: With our preliminary study we tought to exploit PBMCs
capability to induce angiogenesis widely described in literature in order
to treat the vasculopathy-related manifestations of SSc, in patients with
no chance for lipofilling. Our results suggest that PBMCs injection could
represent a treatment option to take into account for SSc patients. The
procedure we used is easy and fast to perform, minimally invasive and
not-operator dependent. We hope our observational and preliminary
study could be considered as a starting point for further research studies
Methylglyoxal-dependent glycative stress and deregulation of SIRT1 functional network in the ovary of PCOS mice
Advanced glycation end-products (AGEs) are involved in the pathogenesis and consequences of polycystic ovary syndrome (PCOS), a complex metabolic disorder associated with female infertility. The most powerful AGE precursor is methylglyoxal (MG), a byproduct of glycolysis, that is detoxified by the glyoxalase system. By using a PCOS mouse model induced by administration of dehydroepiandrosterone (DHEA), we investigated whether MG-dependent glycative stress contributes to ovarian PCOS phenotype and explored changes in the Sirtuin 1 (SIRT1) functional network regulating mitochondrial functions and cell survival. In addition to anovulation and reduced oocyte quality, DHEA ovaries revealed altered collagen deposition, increased vascularization, lipid droplets accumulation and altered steroidogenesis. Here we observed increased intraovarian MG-AGE levels in association with enhanced expression of receptor for AGEs (RAGEs) and deregulation of the glyoxalase system, hallmarks of glycative stress. Moreover, DHEA mice exhibited enhanced ovarian expression of SIRT1 along with increased protein levels of SIRT3 and superoxide dismutase 2 (SOD2), and decreased peroxisome proliferator-activated receptor gamma co-activator 1 alpha (PGC1 alpha), mitochondrial transcriptional factor A (mtTFA) and translocase of outer mitochondrial membrane 20 (TOMM20). Finally, the presence of autophagy protein markers and increased AMP-activated protein kinase (AMPK) suggested the involvement of SIRT1/AMPK axis in autophagy activation. Overall, present findings demonstrate that MG-dependent glycative stress is involved in ovarian dysfunctions associated to PCOS and support the hypothesis of a SIRT1-dependent adaptive response
Open Business Models and Venture Capital Finance
We investigate the differences in venture capital (VC) governance of investee firms with Open Business Models, specifically Open Source Software (OSS), versus closed business models. Due to OSS’s pronounced complexity and uncertainty, we conjecture that VC-backed OSS firms are more frequently staged and syndicated. We present robust empirical evidence from the United States that OSS ventures have more financing rounds and are more likely to be syndicated, and mixed evidence that OSS ventures have a larger number of syndicated investors
The ACEF score: a simple but powerful predictor of short-term mortality in patients with ST-elevation myocardial infarction
Background: several clinical risk scores are available for the risk stratification of patients with ST-elevation myocardial infarction (STEMI), such as the CADILLAC, GRACE, PAMI, TIMI, and Zwolle, but all are complex to use and there is uncertainty on the best one. The age-creatinine-ejection fraction (ACEF) score, has been recently proven effective and proficient as a risk score in cardiac surgery despite its user-friendliness. We thus aimed to compare the performance of the ACEF score in comparison to the other available risk scores in patient with STEMI.
Methods: subjects with STEMI undergoing primary percutaneous coronary intervention at our Institution from 2001 to 2009 were enrolled. The primary end-point was in-hospital all-cause death, whereas long-term all-cause death, long-term cardiac death were appraised as secondary outcomes. ACEF, CADILLAC, GRACE, PAMI, TIMI, and Zwolle risk scores were compared with receiver-operating characteristics (ROC) curves with areas under the curve (AUC), and binary multivariable logistic regression analysis with odds ratios (OR), plus 95% confidence intervals
