Vacutainer ve Enjektör ile Kan Alma Tekniğinin Hemoliz Oranına Etkisinin İncelenmesi

Objective: This study was conducted to determine hemolysis rates for venous blood samples drawn by injector and vacutainer holder and to assess the effect of the venipuncture technique on the process of hemolysis. Material and Method: This cross-sectional and analytical study was conducted with 128 patients who were admitted to the Cardiology and Angio clinics of a university hospital and met the inclusion criteria. One group of patients who were to have routine biochemical tests underwent venipuncture with an injector, and another group with a vacutainer. Results: The serum hemolysis level is not significantly different by gender. No significant correlation was found between blood serum hemolysis levels and age or Body Mass Index with blood drawn with an injector or with a vacutainer. While the serum hemolysis level was on average 0.11 g/dl in blood drawn with an injector, the level in blood drawn with a vacutainer was 0.06 g/dl; the difference was not statistically significant. Conclusion: This study revealed that there was no statistically significant difference between hemolysis rates in blood drawn with an injector or with a vacutainer. However, the hemolysis rates in blood drawn with an injector were almost twice the rates noted in blood drawn with a vacutainer, and this difference may be clinically significant. Amaç: Bu araştırma enjektör ve vacutainer kullanılarak alınan venöz kanlarda hemoliz oranını belirlemek ve kan alma tekniğinin hemoliz gelişimi üzerindeki etkisini değerlendirmek amacıyla yapılmıştır. Gereç ve Yöntem: Kesitsel ve analitik tipte olan bu araştırma, bir üniversite hastanesinin Kardiyoloji ve Anjiyo kliniklerine yatışı yapılan ve araştırmaya dahil edilme kriterlerine uyan 128 hasta ile yürütülmüştür. Rutin biyokimyasal tetkikleri istenilen bir grup hastadan enjektörle, diğer gruptaki hastalardan vacutainer ile kan alınmıştır. Bulgular: Serum hemoliz düzeyi cinsiyetler arasında anlamlı olarak farklı değildir. Enjektör ve vacutainer ile alınan kan örneklerindeki serum hemoliz düzeyleri ile yaş ve Beden Kütle İndeksi arasında anlamlı korelasyon saptanmamıştır. Serum hemoliz düzeyi enjektör ile alınan kanlarda ortalama 0.11 g/dl iken vacutainer ile alınan kanlarda ortalama 0.06 g/dl olup bu fark istatistiksel olarak anlamlı bulunmamıştır. Sonuç: Bu araştırmada enjektör ve vacutainer ile alınan kan örneklerindeki hemoliz oranları istatistiksel olarak anlamlı farklılık göstermemiştir. Ancak enjektörle alınan kanlarda ortalama hemoliz oranı vacutainer ile alınan kanlardan neredeyse iki kat fazladır, bu fark klinik açıdan anlamlı olabilmektedir

Bu bağlamda bu çalışmada COVID-19 tanısı almış dört ayrı olgu, her bir vakaya özgü hemşirelik tanıları doğrultusunda bakım öncelikleri ve kritik hemşirelik girişimleri ile sunulmuşturThe coronavirus disease 2019 (COVID-19) is a new respiratory disease, and as a pandemic has affected hundreds of thousands of people all around the world. In Turkey, as well as all over the world, nurses are on the front lines to provide qualified and safe healthcare services to the society. In these extraordinary conditions, nurses who care for patients diagnosed with COVID-19 should be able to evaluate the patient as a whole. It is also a fact that it is important to provide road maps for effective nursing care so that they can plan nursing interventions. In this context, four different cases diagnosed with COVID-19, their care priorities, and critical nursing interventions are presented in line with the nursing diagnoses specific to each case

Stainability and translucency of potassium aluminum sulfate applied computer-aided design and computer-aided manufacturing materials after coffee thermocycling.

OBJECTIVE The purpose of this in vitro study was to evaluate the effect of potassium aluminum sulfate (alum) application on the stainability and translucency of computer-aided design and computer-aided manufacturing (CAD-CAM) materials after coffee thermocycling (CTC). MATERIALS AND METHODS Disk-shaped specimens (Ø10 × 1 mm; N = 200) were fabricated by using additively (Crowntec [CT] and Varseo Smile Crown Plus [VS]) and subtractively manufactured (Brilliant Crios [RCR], CEREC Block [FC], and Vita Enamic [VE]) CAD-CAM materials and polished. All specimens were randomly divided into two groups as alum applied and control (n = 10). All specimens were then subjected to CTC (10,000 cycles at 5-55°C) and color coordinates were measured at each time interval. Color differences (ΔE00 ) and relative translucency parameters (RTPs) were calculated and the data were statistically analyzed (a = 0.05). RESULTS Among tested time intervals, alum applied specimens had their lowest ΔE00 after alum application (p ≤ 0.006), except for FC (p = 0.177). In addition, alum applied RCR had lower ΔE00 values than its control specimens (p = 0.029). Alum applied specimens had their lowest RTP after CTC (p < 0.001) and alum application decreased the RTP of CT (p = 0.010). CTC reduced the RTP of all materials in control groups (p < 0.001). Alum applied CT had higher RTP than its control specimens (p = 0.049). CONCLUSIONS Alum application's effect on color change varied depending on the material and alum mostly resulted in clinically acceptable changes in translucency. CTC led to unacceptable color and translucency changes based on previously reported threshold values. CLINICAL SIGNIFICANCE Optical properties of CAD-CAM materials and the sustainability of these properties over time is critical for longevity. Alum may improve the color stability of reinforced composite resin when subjected to long-term coffee consumption

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

Early-detection and classification of live bacteria using time-lapse coherent imaging and deep learning

We present a computational live bacteria detection system that periodically captures coherent microscopy images of bacterial growth inside a 60 mm diameter agar-plate and analyzes these time-lapsed holograms using deep neural networks for rapid detection of bacterial growth and classification of the corresponding species. The performance of our system was demonstrated by rapid detection of Escherichia coli and total coliform bacteria (i.e., Klebsiella aerogenes and Klebsiella pneumoniae subsp. pneumoniae) in water samples. These results were confirmed against gold-standard culture-based results, shortening the detection time of bacterial growth by >12 h as compared to the Environmental Protection Agency (EPA)-approved analytical methods. Our experiments further confirmed that this method successfully detects 90% of bacterial colonies within 7-10 h (and >95% within 12 h) with a precision of 99.2-100%, and correctly identifies their species in 7.6-12 h with 80% accuracy. Using pre-incubation of samples in growth media, our system achieved a limit of detection (LOD) of ~1 colony forming unit (CFU)/L within 9 h of total test time. This computational bacteria detection and classification platform is highly cost-effective (~$0.6 per test) and high-throughput with a scanning speed of 24 cm2/min over the entire plate surface, making it highly suitable for integration with the existing analytical methods currently used for bacteria detection on agar plates. Powered by deep learning, this automated and cost-effective live bacteria detection platform can be transformative for a wide range of applications in microbiology by significantly reducing the detection time, also automating the identification of colonies, without labeling or the need for an expert.Comment: 24 pages, 6 figure

Impact of antimicrobial drug restrictions on doctors' behaviors

Background/aim: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics.Materials and methods: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician.Results: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had 5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05).Conclusion: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did

Cotton in the new millennium: advances, economics, perceptions and problems

Cotton is the most significant natural fibre and has been a preferred choice of the textile industry and consumers since the industrial revolution began. The share of man-made fibres, both regenerated and synthetic fibres, has grown considerably in recent times but cotton production has also been on the rise and accounts for about half of the fibres used for apparel and textile goods. To cotton’s advantage, the premium attached to the presence of cotton fibre and the general positive consumer perception is well established, however, compared to commodity man-made fibres and high performance fibres, cotton has limitations in terms of its mechanical properties but can help to overcome moisture management issues that arise with performance apparel during active wear. This issue of Textile Progress aims to: i. Report on advances in cotton cultivation and processing as well as improvements to conventional cotton cultivation and ginning. The processing of cotton in the textile industry from fibre to finished fabric, cotton and its blends, and their applications in technical textiles are also covered. ii. Explore the economic impact of cotton in different parts of the world including an overview of global cotton trade. iii. Examine the environmental perception of cotton fibre and efforts in organic and genetically-modified (GM) cotton production. The topic of naturally-coloured cotton, post-consumer waste is covered and the environmental impacts of cotton cultivation and processing are discussed. Hazardous effects of cultivation, such as the extensive use of pesticides, insecticides and irrigation with fresh water, and consequences of the use of GM cotton and cotton fibres in general on the climate are summarised and the effects of cotton processing on workers are addressed. The potential hazards during cotton cultivation, processing and use are also included. iv. Examine how the properties of cotton textiles can be enhanced, for example, by improving wrinkle recovery and reducing the flammability of cotton fibre
