Influence of synthesis parameters on luminescence emission properties of some sol-gel derived Eu3+ doped willemite phosphors

Europium doped zinc silicate phosphor sample, corresponding to general formula, Zn2-(x+y)EuxLiySi0 4 , (where x = 0.01 or 0.02 and y = 0, 0.01, or 0, 02), have been synthesized by acid, or two steps (acid-base) catalyzed sol-gel processing, in the presence, or absence of Li+ ions, as charge compensator. The obtained xerogel samples was successively annealed, at different steps, up to 1000°C, for 180 minutes time soaking for each temperature. Starting from 700°C temperature, the formation of Si-O-Zn linkage was put in evidence by FT-IR spectra. The appearance of IR signals corresponding to willemite vibration modes has been observed for 900°C calcined samples. At UV excitation beam, the luminescence spectra of Zn2Si0 4 :Eu3+ synthesized phosphors samples show some emission peaks in the red region of spectra, assigned to 5Do—> Fj (j = 0, 1, 2, 3, 4 and 5) spin forbidden f-f transitions of Eu3+ ions, respectively. Specifically they were situated around 575 nm, 590 nm, 615 nm, 624 nm, 650 nm and 700 nm. The most intense emission was observed for the 1000°C calcined sample, with 0.02 moles Eu3+ activator content, prepared with charge compensator

Point-of-care visual medicine in the management of emergency intensive care patients: case study

Moinesti Emergency Country Hospital Moinesti, Romania, The 5th International Congress of the Society of Anesthesiology and Reanimatology of the Republic of Moldova, 16th Edition of the International Course of Guidelines and Protocols in Anesthesia, Intensive Care and Emergency Medicine, 28th Meeting of the European Society for Computing and Technology in Anesthesia and Intensive Care, September 27-29, 2018, Chisinau, the Republic of MoldovaIntroduction: Real-time, bedside (point-of-care) medical image is actually a valuable tool in the diagnosis and management of intensive care patients. In order to illustrate, we present a case with acute chronic respiratory acidosis and hypercapnic coma, when the use of visual medicine shortened the intervention time frame and minimized the complication risks. Case presentation: A male, 64 years old patient, admitted to Internal Medicine with the diagnosis of chronic obstructive bronchopneumopathy exacerbation (respiratory infection) and multiple co-morbidities presents on the 7th day rapid aggravation and has emergency ICU admittance with coma (GCS=8), polypnea (36 breath/min), hypoxemia (SpO2=55%), abundant tracheobronchial secretion retention, arterial hypotension (65/45 mm Hg), tachyarrhythmia (150b/min), acute on chronic respiratory acidosis (pH=7.21, PaCO2=105 mmHg). The emergency management included: video-assisted oro-tracheal intubation (after tube insertion, plugging with abundant secretions) and ventilatory support; vascular access (ultrasound guided central venous and arterial catheterization); fiberoptic-bronchoscopic removal of purulent and bloody abundant secretions; transthoracic echocardiography (severe LV hypokinezia, EF-30%, diffuse subepicardial ischemia). Under complex intensive care treatment (antibiotics, water and electrolyte correction, inotropic support, antiarrhythmic drugs, anticoagulants, mucolytics, antipyretics, enteral nutrition) the condition improves and results in weanning from ventilatory support (the 5th day), from inotropic support (the 7th day) and ICU discharge (the 8th day). Discussion: In critical emergencies, the use of bedside, real-time medical images during diagnostic, monitoring or therapeutic procedures results in several advantages: it shortens the implementation time (tracheal intubation, vascular access), allows rapid evaluation and proper management institution (echocardiography), allows a significant decrease of complication risk (video-assisted laryngoscopy, fiberoptic-bronchoscopy, vascular access). Conclusions: Point-of-care visual medicine – the use of real-time, bedside medical images is an imperative necessity in modern intensive care

Green Accounting in Romania - a Vision to European Integration

The paper debates solutions, points of view and a commune language for Green Accounting. The main purposes of our research are the following: 1.Define the object of Green Accounting 2.Scope 3.Theory and specific practices 4.Disclosure and financial analysis 5.Romanian experience in Green Accounting. How to define Green Accounting? Is Green Accounting a part of Environmental Accounting? How to ensure the balance between business interests and envinronmental protection? Are environmental goals based on Total Quality Management? How to design for Environment? This are some questions proposed to be discused in this paper.

ETIOLOGICAL PROFILE OF INFECTIOUS MENINGITIS AT “DR V. BABES” CLINICAL HOSPITAL OF INFECTIOUS AND TROPICAL DISEASES, BUCHAREST

Infectious meningitis is a serious medical problem that can be fatal if treatment is delayed. Objectives. There are presented clinical and laboratory aspects of patients with suspected meningitis, presented and hospitalized during 2014-2017 at Hospital for Infectious and Tropical Diseases Dr V. Babes Bucharest. Clinical and paraclinical variables that show statistically significant differences depending on the etiology of meningitis have been identified. Methods. Patients who showed signs and symptoms according to the case definition would be included in the study. Clinical and laboratory values were recorded in a database which was then processed to identify statistically significant differences between the group of patients with suspicion only but subsequently not ill against the group of confirmed, and also among different subgroups within the confirmed. Results. Of the 97 cases of infectious meningitis included within 3 years, 53 cases (55%) were viral, 31 (32%) bacterial, one case of fungal meningitis and 12 cases of tuberculous meningitis

Post-anaesthesia pulmonary complications after use of muscle relaxants (POPULAR): a multicentre, prospective observational study

Background Results from retrospective studies suggest that use of neuromuscular blocking agents during general anaesthesia might be linked to postoperative pulmonary complications. We therefore aimed to assess whether the use of neuromuscular blocking agents is associated with postoperative pulmonary complications. Methods We did a multicentre, prospective observational cohort study. Patients were recruited from 211 hospitals in 28 European countries. We included patients (aged ≥18 years) who received general anaesthesia for any in-hospital procedure except cardiac surgery. Patient characteristics, surgical and anaesthetic details, and chart review at discharge were prospectively collected over 2 weeks. Additionally, each patient underwent postoperative physical examination within 3 days of surgery to check for adverse pulmonary events. The study outcome was the incidence of postoperative pulmonary complications from the end of surgery up to postoperative day 28. Logistic regression analyses were adjusted for surgical factors and patients’ preoperative physical status, providing adjusted odds ratios (ORadj) and adjusted absolute risk reduction (ARRadj). This study is registered with ClinicalTrials.gov, number NCT01865513. Findings Between June 16, 2014, and April 29, 2015, data from 22803 patients were collected. The use of neuromuscular blocking agents was associated with an increased incidence of postoperative pulmonary complications in patients who had undergone general anaesthesia (1658 [7·6%] of 21694); ORadj 1·86, 95% CI 1·53–2·26; ARRadj –4·4%, 95% CI –5·5 to –3·2). Only 2·3% of high-risk surgical patients and those with adverse respiratory profiles were anaesthetised without neuromuscular blocking agents. The use of neuromuscular monitoring (ORadj 1·31, 95% CI 1·15–1·49; ARRadj –2·6%, 95% CI –3·9 to –1·4) and the administration of reversal agents (1·23, 1·07–1·41; –1·9%, –3·2 to –0·7) were not associated with a decreased risk of postoperative pulmonary complications. Neither the choice of sugammadex instead of neostigmine for reversal (ORadj 1·03, 95% CI 0·85–1·25; ARRadj –0·3%, 95% CI –2·4 to 1·5) nor extubation at a train-of-four ratio of 0·9 or more (1·03, 0·82–1·31; –0·4%, –3·5 to 2·2) was associated with better pulmonary outcomes. Interpretation We showed that the use of neuromuscular blocking drugs in general anaesthesia is associated with an increased risk of postoperative pulmonary complications. Anaesthetists must balance the potential benefits of neuromuscular blockade against the increased risk of postoperative pulmonary complications
