Prevention of workplace violence in ED nursing using the implementation of an educational program and a new reporting tool
No full textThe Emergency Department (ED) is a place that regularly deals with acute scenarios and people that are generally sensitive in nature. In a fast-paced environment such as this, people can be emotionally charged and react in different ways. Unfortunately, nurses in the ED tend to be most affected. Literature shows that workplace violence incidents that occur tend to involve ED nurses. Furthermore, ED nurses are more inclined to have an attitude that makes them think that any acts of transgression are “part of the job” and incidents usually go underreported. Moreover, reporting tools are usually difficult to use and tend to be a barrier to reporting workplace violence. In this evidence-based project, ED nurses will participate in an educational prevention program that will help equip them with the knowledge and awareness that is needed to decrease the incidence of workplace violence. Furthermore, a new, easy-to-use reporting tool will be implemented for ED staff. An implementation of an easier reporting tool and an education prevention program on the incidence of workplace violence will help reduce the number of future incidents of workplace violence. The purpose of this evidence-based project is to create a “zero tolerance” workplace culture for ED nurses that ultimately decreases the incidence of workplace violence. Based on research, an educational program and new reporting tool will be implemented at an urban community hospital in Westchester. Included is a purpose statement, and operational and conceptual definition, PICO questions, and an evidence-based practice protocol for workplace violence
Age, smoking, hypertension, and aortic aneurysm: Interactions and risks
No full textBackground/Aim: Aortic aneurysm is the bulging of a weakened portion of the aorta. The aorta is the major blood vessel that feeds blood (carrying oxygen, nutrients and water) to the tissues of the body. When a portion of the wall of the aorta becomes weak, blood pushing against the vessel wall can cause it to bulge like a balloon (aneurysm) leading to aortic dissection (a tear in the wall of the aorta that can cause life-threatening bleeding or sudden death). Blood pressure is the force arterial blood exerts on the wall of the artery. When this pressure is consistently high above 140/100 mmHg it is referred to as hypertension. As an individual gets older over time, physiological functions of the body depreciate leading to some abnormalities. Smoking is the consumption of tobacco mostly by inhalation of the smoke that is produced from burning the tobacco. This review article examines the close interactions between age, smoking, hypertension and aortic aneurysm, with a view to understanding mechanisms by which these factors predispose a patient to an aortic aneurism. It is also to observe if these factors interfere with treatment and recovery from aneurysms. Conclusion: After careful review, it is observed that age and smoking are risk factors for hypertension, and together with hypertension, the three factors predispose an individual to high risk for aortic aneurysm
Laser spears for the Russian army
No full textThe paper is devoted to the problem of high-energy solid-state laser arms, demonstrating the highest efficiency in the terms of weight and sizing. We can predict a very bright future for such laser systems as a significant means of defeating the enemy. The problem of scalability for such an approach based on fiber laser technology is the key question of our days for many companies of the world. At the same time, it is clear that a tactical LW based on solid-state technology with a weight factor of 5 kg / kW with the total weight of a laser complex significantly less than a ton can be created. But the level of output power around 500 kW is very close to the limit for the fiber technology..
Addition of dydrogesterone to vaginal progesterone and transfer postponement improve outcomes in patients with low progesterone levels in hormonally substituted cycles for frozen-thawed embryo transfer
No full textPurpose: Adding dydrogesterone (DYD) to vaginal micronized progesterone (VMP) and postponing embryo transfer in order to improve outcomes in patients with low progesterone (P) levels in hormonally substituted cycles prior to frozen/thawed embryo transfer (FET). Methods: Endometrial preparation comprised sequential administration of vaginal estradiol until endometrial thickness reached 7 mm, followed by transdermal estradiol combined with 800 mg/day VMP. Our previous analysis of serum P levels on FET day showed that the optimal P level was > 11 ng/mL for live birth. Serum P was measured on day1 (D1) following exogenous VMP introduction in the evening. When P levels were > 11 ng/mL, FET was performed “in phase” on day-2, day-3, or day-5 depending on embryo stage at cryopreservation (n = 139 cycles). When P levels were < 11 ng/mL, DYD 10 mg three times a day orally, was added to VMP and FET was postponed by one day (n = 237 cycles, 63%). The primary endpoint was the comparison of live birth rates (LBR) between the two groups.Results: Mean serum P level on D1 was 10.2 + 3.7 ng/mL. Characteristics of patients in both groups were similar for age, body mass index, endometrial thickness prior to P introduction, quality of transferred embryos, and embryo transfer stage. Regarding the primary endpoint, LBR was similar between the VMP+DYD group and the VMP group (26.1% vs. 27.3%, NS). Conclusion: These results suggest that adding DYD to VMP and postponing the transfer in patients with low P levels in hormonally substituted FET cycles might optimize outcomes
Assessment of knowledge on breast self-examination among female adolescent: a cross-sectional study
No full textBackground: Breast self-examination is the most important screening method for early detection and diagnosis of Breast cancer. Females assess their breasts regularly to detect any abnormalities to seek instant medical attention. Objectives: The main objective of the study was to assess the knowledge on breast self-examination among female adolescents of Nepal.Method: A cross-sectional study was conducted using self-structured questionnaires among female adolescents of Model Multiple College, Dhanusha. The sample size was 120 participants. Probability proportionate stratified sampling technique was used to collect the data from October 28th to November 12th, 2013. Data were processed through Statistical Package for Social Sciences version 16 and analyzed using descriptive statistics.Results: Out of 120 participants 67.5% participants had knowledge about breast cancer and 40% had knowledge of breast self-examination (BSE). Most of them (94.2%) had a poor knowledge of BSE followed by 5.8% of participants with a moderate level of knowledge of BSE. The mean knowledge score was 18.7 ± 3.5. The majority (66.7%) of participants were from science faculties. More than half (51.7%) of participants stated source of information on BSE was health personnel. Only 25% of the respondent had a family history of breast cancer. Conclusion: The study revealed that most (94.2%) of the participants had poor knowledge of breast self-examination. There is further need for awareness and health education on breast self-examination. 
Optimization of the fermentation process, characterization and antioxidant activity of exopolysaccharides produced from Azotobacter As101
No full textAzotobacter was selectively isolated and purified from the soil samples of Xinjiang Salt Lake Scenic spot, the fermentation technology of exopolysaccharides (EPS) by Azotobacter was optimized, and the antioxidant activity of exopolysaccharides (EPS) was studied. The bacteria were isolated and purified from the soil samples by the scribing method and the 16SrRNA gene was used for molecular identification. The carbon source, fermentation time, inoculation amount and pH of target bacteria in the exopolysaccharides (EPS) fermentation process were optimized through single-factor experiments and their antioxidant activity was measured. Eight types of Azotobacter were isolated and purified from the soil samples of Salt Lake scenic spot. Among them, As101, which showed 99.58% homology with Azotobacter salinestris, was selected as the target strain. Through single-factor experiments which used exopolysaccharides (EPS) yield and exopolysaccharides content as indexes, the optimal conditions for the As101 fermentation process were determined as follows: fermentation temperature 35, fermentation time 96h, pH 7 and mannitol as carbon source. Exopolysaccharides content from Azotobacter salinestris was 61.35% and the yield was 6.34 g/L. The results of the exopolysaccharides (EPS) antioxidant activity experiment under optimal conditions showed that As101 EPS had excellent scavenging ability against DPPH free radical, ABTS free radical and hydroxyl free radical, with IC50 values of 6.11 mg/ml, 2.42 mg/ml and 9.57 mg/ml, respectively. As101 with high yield and high exopolysaccharides content was isolated from saline soil in a special environment of Xinjiang, and the EPS obtained showed excellent antioxidant activity. The Azotobacter found in this study would provide the material basis for further opening up the adsorption of exopolysaccharides on heavy metals and the improvement of saline-alkali soil and contribute to further understanding of the structure and other activities of exopolysaccharides derived from Azotobacter
Pretreatments, dehydration methods and packaging materials: effects on the nutritional quality of tomato powder: a review
No full textPretreatments and drying are commonly used before drying tomatoes to inactivate enzymes, improve the drying process, and improve the quality of dried tomato powders. In this review, the effects of different pretreatments (osmotic solutions), dehydration methods, and packaging materials on the quality attributes of tomato powder were summarized. These include pretreatments and osmotic agent solutions (potassium metabisulfite, calcium chloride, sodium metabisulphite, ascorbic acid, citric acid, sodium chloride, and sodium benzoate), thermal blanching (steam blanching and hot water) and non-thermal-processes-like-freezing, sulfuring, etc. and drying methods (oven, sun, and indirect solar dryer). The tomato powders were dried to preserve, store, and transport them. Drying implies not only physical changes, which the consumer can easily detect through visual inspection but also chemical modifications. These are responsible for alterations in color, flavor, and nutritional value, which compromise the overall quality of the final tomato powder. Maximum lycopene, vitamin A, and C contents were found in freeze-dried and direct sundried than samples dried using other methods at low drying temperatures. Freeze driers showed in keeping the nutritional quality of tomato powder with a combination of different pretreatments. Different pretreatments including osmotic agent solutions have their own merits and demerits for the final tomato powder. To overcome the drawbacks of nutritional quality, non-thermal pretreatment categories may be a better alternative to thermal blanching, and more fundamental research is required for better design and scale-up
A relevant article, white papers and other documents concerning the mRNA vaccine: an interesting collection useful to better understand some phenomena and to generate hypotesys
No full textThe aim of this work is to report some interesting references and documents related to the mRNA vaccine. Every cited reference can act as an instrument to better understand what some independent researchers find: this work is mainly focused on the public debate related presence/absence of graphene derivates in some vaccine vials for COVID-19. Relevant classic articles White Papers or other kinds of a document are useful instruments to better clarify some crucial aspects of this infectious disease, its epidemiology and the efficacy of the measure adopted (preventive, therapeutic, or vaccine).If the reviewed article show an intrinsic recognized international value other kinds of source like a White Paper or other documents can be of interest to generate hypotheses or to open public discussion on crucial topics. For this reason, it is useful to use this method also in the discussion related to impurity profiles in new innovative bio-pharmaceuticals like the mRNA vaccine. The fact that this product was introduced with an emergency authorization, whit reduced the time of experimentation and due to the lack of official quality information related to some raw materials used authorizes us to use also this method.Even if the international official regulatory agency does not find this substance in the control for release of the lots it is interesting to more deeply investigate what funded by an independent researcher in some vials of vaccine or sample patient’s blood after vaccination. This reference even if not a smoking gun the same can stimulate the reasoning about the general concept involved. It is needed, to read this work, to consider the intrinsic limitation of some of the study research reported (White Paper) or the other documents
Atrial fibrillation in elite athletes. What is missing?
No full textAlthough the beneficial effect of physical activity in the general population is well established, in elite athletes under vigorous physical activity, the effect on the electrical system of the heart is controversial. Indeed, several studies have shown an increased rate of atrial fibrillation among athletes, whereas others suggest that improved exercise capacity with training reduces atrial fibrillation recurrence. The pathophysiologic explanation of that discrepancy is missing, although several underlying mechanisms have been proposed. Taking into account the current knowledge, it seems that, although the beneficial effects of exercise are well recognized, there are conflicting data regarding the relation of the occurrence - the rate of atrial fibrillation to high-volume exercise and too long-term training. Its significance on the quality of life especially in highly trained athletes remains to be elucidated. Therefore, this short review will try to discuss this discrepancy and hopefully underlie the arising arguments.
