The Sustanability of Public Finance in New Members States of European Union

<p>The issue of public finance sustainability is very important for all EU member states in the actual context after the economic crisis. This article makes an analysis of the sustainability of public finances for the new member states (which joined EU in 2004 and 2007). Firstly, we try to analyze the impact of the economic crisis on public finances sustainability. The sustainability of public finances can be reflected through the level of public debt and budget deficit for a country. For this reason the article presents the evolution of budget deficits for NMS 12 before and after the recent economic crisis. Based on the econometric regression the correlation between economic growth rate (indicator used for measuring the economic evolution) and the budget deficit is revealed. Results for Romania and NMS 12 are quite similar; fact that tells us that the status of public finances is following the same trend in Romania as in the NMS 12.</p

The effect of an organic waste compost on the agro-chemical characteristics of the soil, and the mineral composition of the sunflower leaves

Aiming to increase the use of natural resources and unexplored opportunities in industrial and agricultural practices, the marine algae biomass, that causes serious environmental problems in the Romanian Black Sea coast, was used in association with another two organic wastes, farmyard manure from cattle-breeding farms and sewage sludge resulted from the waste water treatment, to produce a compost suitable as organic fertilizer for plant cultivation in ecologic farming systems. Four variants of compost, first representing equal parts (33.33%) of those three components, and the other three proportions of 50% of each component, the difference being ensured in a ratio of 25% of each of the other two components, have been tested in a field experiment to assess their effects, both on the agro-chemical properties of the soil and on the sunflower plants development and crops. Until the phase of sunflower calathidia formation, the compost containing 50% farmyard manure influenced the best plant development in terms of height and number of leaves, then, at the end of vegetation period, the best plant development took place under the influence of compost prevalent in marine algae. The mobile forms of N and P were statistically differentiated depending on the dose of compost, the maximum dose generating the lowest content levels in the soil, as a result of higher absorption of these chemical elements in plants. The content of P and Ca in sunflower leaves recorded significant differences

Biocompatible Chitosan-Based Hydrogels for Bioabsorbable Wound Dressings

Supramolecular hydrogels based on chitosan and monoaldehydes are biomaterials with high potential for a multitude of bioapplications. This is due to the proper choice of the monoaldehyde that can tune the hydrogel properties for specific practices. In this conceptual framework, the present paper deals with the investigation of a hydrogel as bioabsorbable wound dressing. To this aim, chitosan was cross-linked with 2-formylphenylboronic acid to yield a hydrogel with antimicrobial activity. FTIR, NMR, and POM procedures have characterized the hydrogel from a structural and supramolecular point of view. At the same time, its biocompatibility and antimicrobial properties were also determined in vitro. Furthermore, in order to assess the bioabsorbable character, its biodegradation was investigated in vitro in the presence of lysosome in media of different pH, mimicking the wound exudate at different stages of healing. The biodegradation was monitored by gravimetrical measurements, SEM microscopy and fractal analyses of the images. The fractal dimension values and the lacunarity of SEM pictures were accurately calculated. All these successful investigations led to the conclusion that the tested materials are at the expected high standards

Intubation Practices and Adverse Peri-intubation Events in Critically Ill Patients from 29 Countries

Importance: Tracheal intubation is one of the most commonly performed and high-risk interventions in critically ill patients. Limited information is available on adverse peri-intubation events. Objective: To evaluate the incidence and nature of adverse peri-intubation events and to assess current practice of intubation in critically ill patients. Design, Setting, and Participants: The International Observational Study to Understand the Impact and Best Practices of Airway Management in Critically Ill Patients (INTUBE) study was an international, multicenter, prospective cohort study involving consecutive critically ill patients undergoing tracheal intubation in the intensive care units (ICUs), emergency departments, and wards, from October 1, 2018, to July 31, 2019 (August 28, 2019, was the final follow-up) in a convenience sample of 197 sites from 29 countries across 5 continents. Exposures: Tracheal intubation. Main Outcomes and Measures: The primary outcome was the incidence of major adverse peri-intubation events defined as at least 1 of the following events occurring within 30 minutes from the start of the intubation procedure: cardiovascular instability (either: systolic pressure &lt;65 mm Hg at least once, &lt;90 mm Hg for &gt;30 minutes, new or increase need of vasopressors or fluid bolus &gt;15 mL/kg), severe hypoxemia (peripheral oxygen saturation &lt;80%) or cardiac arrest. The secondary outcomes included intensive care unit mortality. Results: Of 3659 patients screened, 2964 (median age, 63 years; interquartile range [IQR], 49-74 years; 62.6% men) from 197 sites across 5 continents were included. The main reason for intubation was respiratory failure in 52.3% of patients, followed by neurological impairment in 30.5%, and cardiovascular instability in 9.4%. Primary outcome data were available for all patients. Among the study patients, 45.2% experienced at least 1 major adverse peri-intubation event. The predominant event was cardiovascular instability, observed in 42.6% of all patients undergoing emergency intubation, followed by severe hypoxemia (9.3%) and cardiac arrest (3.1%). Overall ICU mortality was 32.8%. Conclusions and Relevance: In this observational study of intubation practices in critically ill patients from a convenience sample of 197 sites across 29 countries, major adverse peri-intubation events - in particular cardiovascular instability - were observed frequently
