Analysis of Global Systems, Support Centers, and Weather Units Aviation

This paper examines the analysis of meteorological observations concerning wind direction and intensity. These observations are typically found in regular weather reports, which play a crucial role in the safe arrival and departure of aircraft, and provide vital information about current conditions along airport runways. To ensure accuracy, the locations of wind sensors along runways must be specified in routine weather reports. Furthermore, reported wind information data should be linked to the specific sections of the runway for which the data are representative. In cases where wind observations are available from multiple tracks, the relevant track information should also be included in routine weather reports, alongside the corresponding wind data. For surface wind conditions, the observations included in the METAR reports should accurately represent the entire runway, and it is important to indicate the specific runway or runway sections to which the observations pertain

Sex difference and intra-operative tidal volume: Insights from the LAS VEGAS study

BACKGROUND: One key element of lung-protective ventilation is the use of a low tidal volume (VT). A sex difference in use of low tidal volume ventilation (LTVV) has been described in critically ill ICU patients.OBJECTIVES: The aim of this study was to determine whether a sex difference in use of LTVV also exists in operating room patients, and if present what factors drive this difference.DESIGN, PATIENTS AND SETTING: This is a posthoc analysis of LAS VEGAS, a 1-week worldwide observational study in adults requiring intra-operative ventilation during general anaesthesia for surgery in 146 hospitals in 29 countries.MAIN OUTCOME MEASURES: Women and men were compared with respect to use of LTVV, defined as VT of 8 ml kg-1 or less predicted bodyweight (PBW). A VT was deemed 'default' if the set VT was a round number. A mediation analysis assessed which factors may explain the sex difference in use of LTVV during intra-operative ventilation.RESULTS: This analysis includes 9864 patients, of whom 5425 (55%) were women. A default VT was often set, both in women and men; mode VT was 500 ml. Median [IQR] VT was higher in women than in men (8.6 [7.7 to 9.6] vs. 7.6 [6.8 to 8.4] ml kg-1 PBW, P < 0.001). Compared with men, women were twice as likely not to receive LTVV [68.8 vs. 36.0%; relative risk ratio 2.1 (95% CI 1.9 to 2.1), P < 0.001]. In the mediation analysis, patients' height and actual body weight (ABW) explained 81 and 18% of the sex difference in use of LTVV, respectively; it was not explained by the use of a default VT.CONCLUSION: In this worldwide cohort of patients receiving intra-operative ventilation during general anaesthesia for surgery, women received a higher VT than men during intra-operative ventilation. The risk for a female not to receive LTVV during surgery was double that of males. Height and ABW were the two mediators of the sex difference in use of LTVV.TRIAL REGISTRATION: The study was registered at Clinicaltrials.gov, NCT01601223

A Five-Year Analysis of Antibiotic Resistance Trends among Bacteria Identified in Positive Urine Samples in a Tertiary Care Hospital from Bucharest, Romania

The rise of multidrug-resistant bacteria (MDR) has resulted in limited treatment options and poorer outcomes for patients. The objective of this study was to analyze the overall antibiotic resistance trends and distribution for pathogens identified in urine samples at the National Institute of Infectious Diseases “Prof. Dr. Matei Balș” from Bucharest, Romania, over a 5-year period. Antibiotic susceptibility testing was performed using automatic systems and the disk diffusion method. ESBL- and carbapenemases-producing strains were identified using immunochromatography tests, and ROSCO Diagnostica kits were used for definitive confirmation. All results were interpreted according to EUCAST clinical breakpoints. Gram-negative rods (GNR) had overall resistance rates higher than 50% for penicillin and 40% for 3rd- and 4th-generation cephalosporins. Escherichia coli resistance to fosfomycin (3%) and nitrofurantoin (2%) remains low, and 33.30% of E. coli, 48% of Klebsiella spp., and 37% of Pseudomonas aeruginosa isolates were multidrug-resistant (MDR). All Acinetobacter baumannii isolates were MDR by the last year of the study. For Gram-positive cocci (GPC), 37% of all Enterococcus faecium strains and 2% of Enterococcus faecalis were vancomycin-resistant (VRE). E. coli’s incidence in UTIs’ etiology is on a downward trend. The incidence of Klebsiella spp. and GPCs is rising. Antibiotic stewardship strategies should be implemented after carefully considering regional variations in etiology and resistance trends

CONSIDERATIONS ON THE EFFECTS OF TASTE CHANGES CAUSED BY LONG-COVID ON NUTRITION AND ORAL HEALTH

Long-COVID, alternatively referred to as post-COVID syndrome, has garnered significant attention among individuals affected by SARS-CoV-2 as well as healthcare practitioners. The phenomenon began to be perceived as a secondary epidemic that is impacting an increasing number of individuals on a global scale. A notable proportion of individuals who have contracted SARS-CoV-2, including those with mild or moderate symptoms, have reported alterations in their sense of taste subsequent to the resolution of the acute stage of the disease. Patients sometimes report a frequent occurrence of an inability to interpret food tastes in a typical manner or an encounter with distorted taste perceptions. The present state of literature related to oral manifestations associated with long-term COVID-19 is still in the context of ongoing study. The nutritional imbalance observed in individuals with long-COVID syndrome may be attributed to changes in taste and smell, which affect both the quality and quantity of food intake. The changes in taste perception observed in persons suffering with long-COVID involve a complex and significant immune response that has implications for the nutritional and oral health of these patients

Traditional Medicinal Plants—A Possible Source of Antibacterial Activity on Respiratory Diseases Induced by <i>Chlamydia pneumoniae</i>, <i>Haemophilus influenzae</i>, <i>Klebsiella pneumoniae</i> and <i>Moraxella catarrhalis</i>

Background. Nowadays, phytotherapy offers viable solutions in managing respiratory infections, disorders known for considerable incidence in both children and adults. In a context in which more and more people are turning to phytotherapy, finding new remedies is a topical goal of researchers in health and related fields. This paper aims to identify those traditional medicinal plants that show potentially antibacterial effects against four Gram-negative germs (Chlamydia pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, and Moraxella catarrhalis), which are considered to have high involvement in respiratory infections. Furthermore, a comparison with Romanian folk medicines was performed. Methods. An extensive review of books and databases was undertaken to identify vegetal species of interest in the context of the topic. Results. Some traditional Romanian species (such as Mentha × piperita, Thymus vulgaris, Pinus sylvestris, Allium sativum, Allium cepa, Ocimum basilicum, and Lavandulaangustifolia) were identified and compared with the plants and preparations confirmed as having antibacterial effects against specific germs. Conclusions. The antibacterial effects of some traditionally used Romanian medicinal plants are poorly investigated, and deserve further attention

Heritage ethnographic objects - antimicrobial effects of chitosan treatment

[EN] Chitosan is a natural polymer, which presents, according to studies made up to present, low toxicity and good biocompatibility. Recent studies are focused not only on its antimicrobial effects on textiles, because this polysaccharide leads to improvements such as: shrink resistance, dye uptake etc. Two Romanian traditional shirts were non-invasively tested by applying Chitosan and by investigating the SEM images, before and after applying the chitosan. The paper underlines the surface modifications of tested textiles using chitosan. The odd agents on the fibres surfaces were removed and the limitation of the number of microorganisms was observed[Otros] Chitosanul este un polimer natural care, conform studiilor realizate pân¿ în prezent, prezint¿ o toxicitate sc¿zut¿ ¿i o bun¿ biocompatibilitate. Studii recente, care se concentreaz¿ nu doar pe efectele sale antimicrobiene asupra materialelor textile, au eviden¿iat c¿ aceast¿ polizaharid¿ conduce la îmbun¿t¿¿iri din punctul de vedere al rezisten¿ei la contrac¿ie, precum rezisten¿a la contrac¿ie, absorb¿ia coloran¿ilor etc. Dou¿ c¿m¿¿i tradi¿ionale române¿ti (ii) au fost testate neinvaziv prin aplicarea chitosanului ¿i prin investigarea imaginilor SEM, înainte ¿i dup¿ tratamentul cu chitosan.

PRELIMINARY STUDY ON ANTIMICROBIAL EFFICIENCY OF SOME COMMON CHEMICAL SUBSTANCES WITH A DISINFECTING CHARACTER ON IMPRESSION MATERIALS USED IN IMPLANT-PROSTHETIC REHABILITATION

Purpose. Starting from a very recent event on the market of disinfectants, where for many years very diluted disinfectant products were marketed in Romania, the antimicrobial activity being non-existent, we tried, on the basis of simple experiments, to study the antimicrobial efficiency of the active substances of some common products used on impression materials in implant-prosthetic rehabilitation, but also in classical dental prosthetics and in orthodontics and dentofacial orthopedics, products approved and used in the European Union. Material and method. 7 decontamination and/or disinfectant products were tested for qualitative screening for the sensitivity to different microbial strains as well as for quantitative testing of antimicrobial activity. Results and discussions. The study results for the two objectives are influenced by the active substances of the tested products. Conclusions. Decontamination of dental impressions must also become a certainty in implant-prosthetic rehabilitation, in classical dental prosthetics and in orthodontics and dentofacial orthopedics even if this work is disregarded and ignored by many practitioners
