An Efficient Vector System to Modify Cells Genetically

The transfer of foreign genes into mammalian cells has been essential for understanding the functions of genes and mechanisms of genetic diseases, for the production of coding proteins and for gene therapy applications. Currently, the identification and selection of cells that have received transferred genetic material can be accomplished by methods, including drug selection, reporter enzyme detection and GFP imaging. These methods may confer antibiotic resistance, or be disruptive, or require special equipment. In this study, we labeled genetically modified cells with a cell surface biotinylation tag by co-transfecting cells with BirA, a biotin ligase. The modified cells can be quickly isolated for downstream applications using a simple streptavidin bead method. This system can also be used to screen cells expressing two sets of genes from separate vectors

The PROVENT-C19 registry: A study protocol for international multicenter SIAARTI registry on the use of prone positioning in mechanically ventilated patients with COVID-19 ARDS

Background The worldwide use of prone position (PP) for invasively ventilated patients with COVID-19 is progressively increasing from the first pandemic wave in everyday clinical practice. Among the suggested treatments for the management of ARDS patients, PP was recommended in the Surviving Sepsis Campaign COVID-19 guidelines as an adjuvant therapy for improving ventilation. In patients with severe classical ARDS, some authors reported that early application of prolonged PP sessions significantly decreases 28-day and 90-day mortality. Methods and analysis Since January 2021, the COVID19 Veneto ICU Network research group has developed and implemented nationally and internationally the "PROVENT-C19 Registry", endorsed by the Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care. . .'(SIAARTI). The PROVENT-C19 Registry wishes to describe 1. The real clinical practice on the use of PP in COVID-19 patients during the pandemic at a National and International level; and 2. Potential baseline and clinical characteristics that identify subpopulations of invasively ventilated patients with COVID-19 that may improve daily from PP therapy. This web-based registry will provide relevant information on how the database research tools may improve our daily clinical practice. Conclusions This multicenter, prospective registry is the first to identify and characterize the role of PP on clinical outcome in COVID-19 patients. In recent years, data emerging from large registries have been increasingly used to provide real-world evidence on the effectiveness, quality, and safety of a clinical intervention. Indeed observation-based registries could be effective tools aimed at identifying specific clusters of patients within a large study population with widely heterogeneous clinical characteristics.

Judicial outcome and follow up of abused child protection acts in a pediatric emergency department: 12-year experience in a third level pediatric hospital

Background: Italian laws allow the protection of a child who is suspected to be a victim of abuse through a procedure that can be put in motion by the attending physician in any Emergency Department (article nr. 403 Civil Code) with a temporarily suspension of parental authority. This study aims at evaluating both the appropriateness of the activation of the protection procedure by ED doctors in cases of suspected child abuse in terms of judicial confirmation and how it impacts children in the long-term. Methods: We selected cases in which the procedure was activated due to suspected child abuse. The children were admitted to the ED of a tertiary children hospital from 2006 to 2018. We then reviewed the medical charts and collected data from the social services through a questionnaire concerning the long-term outcomes. Results: Twenty-eight patients were included (75% females, mean age 13.8 years). In 90% of cases the activation of the procedure in the ED was followed by a Court confirmation. Evaluation of long term outcome was possible in 22 cases. Among them, a positive social outcome was achieved in 15 cases (68.2%). The remaining abandoned the program or had critical reintegration in the family. Eighteen percent of patients developed major issues such as aberrant behaviours, substance abuse or psychiatric disorders. Conclusions: This report identifies a good ability of ED doctors in the activation of an emergency procedure to protect the child. Overall, the social outcome was good for nearly 70% of the patients, highlighting the importance of activation of social support programs for child abuse

Ranking and Selecting Components to Build Systems

Component-Based Software Engineering (CBSE) allows developers to build systems using existing components. Developers need to find the best set of components that implements most of required features. Retrieving components manually can be very complicated and time expensive. Tools that partially automate this task help developers to build better systems with less effort. This paper proposes a methodology for ranking and selecting components to build an entire system instead of retrieving just a single component. This methodology was developed in the European project CLARiFi (CLear And Reliable Information For Integration)
