Fatty acid composition of fl owers of Crepis foetida subsp. rhoeadifolia from Turkey

This study aims to describe the fatty acid composition of flowers of Crepis foetida subsp. rhoeadifolia. In order todefine qualitative and quantitative profile, fatty acids were derived to their methyl esters, and then these wereanalyzed by gas chromatography - flame ionization detector. 20 fatty acids were determined in the oil. Palmitic(C 16:0), myristic (C 14:0), and linoleic acids (18:2 ω6) were found to be major fatty acids. Total saturatedfatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids (PUFA) were 62.67%, 17.54%, and19.79%, respectively. Also, total essential fatty acids (EFA) were determined ad 14.48%. Therefore, the oil canbe considered as a new source of PUFA, especially EFA

Evaluation of renal near-infrared spectroscopy for predicting extubation outcomes in the pediatric intensive care setting

BackgroundIn pediatric intensive care units, extubation failure following invasive mechanical ventilation poses significant health risks. Determining readiness for extubation in children can minimize associated morbidity and mortality. This study investigates the potential role of renal near-infrared spectroscopy (RrSO2) in predicting extubation failure in pediatric patients.MethodsA total of 84 patients aged between 1 month and 18 years, mechanically ventilated for at least 24 h, were included in this prospective study. RrSO2 levels were measured using near-infrared spectroscopy before and during an extubation readiness test (ERT). The primary outcome measure was extubation failure, defined as a need for reintubation within 48 h.ResultsOf the 84 patients, 71 (84.6%) were successfully extubated, while 13 (15.4%) failed extubation. RrSO2 was found to be lower in the failed extubation group, also decrease in RrSO2 values during ERT was significantly greater in patients with extubation failure. ROC analysis indicated a decrease in ΔRrSO2 of more than 6.15% from baseline as a significant predictor of extubation failure, with a sensitivity of 0.984 and a specificity of 0.889.ConclusionMonitoring changes in RrSO2 values may serve as a helpful tool to predict extubation failure in pediatric patients. Further multi-center research is warranted to improve the generalizability and reliability of these findings

THE EFFECT OF COVID-19 OUTBREAK ON THE MENTAL STATUS OF HEALTH CARE PROFESSIONALS IN THE PEDIATRIC INTENSIVE CARE UNIT

Background: Coronavirus disease 2019 (COVID-19) may affect the mental status of health care professionals. The purpose of our study is to evaluate the mental health effects of the COVID-19 epidemic on health care professionals in the pediatric intensive care units (PICUs). Subjects and methods: Our study was conducted prospectively between 01.04.20 and 10.04.20. The created questionnaire was applied to health care professionals through online platforms. Thus it was involved in 5 different institutions that participated from different regions of Turkey. With the questionnaire, we applied; the participants\u27 age, gender, the general status of contamination and the level of COVID-19 knowledge were questioned. Besides; Beck Anxiety Scale, Acute Stress Scale (PCL-5), STAI-1 and STAI-2 (State and Trait Anxiety Inventory 1-2) scales were used to determine the anxiety levels. Results: A survey of 210 participants, 86 (41%) doctors, 124 (59%) nurses, were included in our study. When we evaluate the Beck anxiety levels, the majority of the participants (44%) were normal, while about one third had mild anxiety. When we evaluated the acute stress scale, all participants had a certain amount of stress levels. The majority (80 people each (38%)) experienced mild and moderate acute stress. Being female and having chronic disease poses a high risk for anxiety (OR, 0.330; 95% CI, 0.087-1.250, p <0.05 and OR, 0.246; 95% CI, 0.068-1.116, p<0.05), preoccupation (OR, 0.603; 95% CI 0.261-1.395, p<0.05 and OR, 0.433; 95% CI, 0.122-1.538, p<0.05) and acute stress (OR, 0.294; 95% CI, 0.033-2.649, p<0.05 and OR, 0.317; 95 % CI 0.060-1.679, p<0.05). Professional definition, marital status and having a child do not pose any risk factors. Conclusion: Our study has shown that the COVID-19 outbreak affects the mental status of health care professionals working at PICU at various levels

Multiple biological activities of two Onosma species (O. sericea and O. stenoloba) and HPLC-MS/MS characterization of their phytochemical composition

Members of the Onosma genus are widely used in folk medicine and they have great interest in the pharmaceutical industry. In this study, phytochemical characterization, antioxidant activity (2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP), cupric reducing antioxidant capacity (CUPRAC), metal chelation, and phosphomolybdenum assays), enzyme inhibition (acetylcholinesterase (AChE), butyrylcholinesterase (BChE), α-amylase, α-glucosidase, and tyrosinase), antimicrobial activity (microdilution method), genotoxic and antigenotoxic (by using Drosophila melanogaster larvae and Comet assay) potentials of Onosma sericea Willd. and Onosma stenoloba Hausskn. ex Riedl. were investigated. Additionally, the bioactive compounds were identified by high performance liquid chromatography-mass spectrometry/mass spectrometry (HPLC-MS/MS) analysis. Generally, O. sericea showed stronger antioxidant activity, while O. stenoloba extract exhibited stronger enzyme inhibitory abilities (cholinesterases and α-amylase). The protective effects of extracts, at the concentration range from 25 to 400 μg/mL, against hydroxyl radical-induced DNA damage were dose-dependent, increasing with a higher dosage. The extracts at the highest concentration (80 mg/mL) showed the absence of genotoxicity in vivo. Antigenotoxic effects were evident after treatment with both extracts, with a percentage reduction of over 80 %. Overall antimicrobial activity of studied extracts was weak, with the lowest minimal inhibitory concentration values (MIC) of 2.5 mg/mL. Taken together, obtained results showed that tested Onosma species can be considered as promising sources of bioactive phytochemicals for pharmacological purposes.Publishe

Prenatal diagnosis of Caudal Regression Syndrome : a case report

BACKGROUND: Caudal regression is a rare syndrome which has a spectrum of congenital malformations ranging from simple anal atresia to absence of sacral, lumbar and possibly lower thoracic vertebrae, to the most severe form which is known as sirenomelia. Maternal diabetes, genetic predisposition and vascular hypoperfusion have been suggested as possible causative factors. CASE PRESENTATION: We report a case of caudal regression syndrome diagnosed in utero at 22 weeks' of gestation. Prenatal ultrasound examination revealed a sudden interruption of the spine and "frog-like" position of lower limbs. Termination of pregnancy and autopsy findings confirmed the diagnosis. CONCLUSION: Prenatal ultrasonographic diagnosis of caudal regression syndrome is possible at 22 weeks' of gestation by ultrasound examination
