The Caring Experience of Fetal Loss and Termination of Pregnancy Through the Eyes of Gynecological Medical and Surgical Nurses
Authors: Fowler Susan B. , Miller Harriet D. , Livingston Taylor
Published: June 2022

Nurses care for women experiencing fetal loss as a result of elective or therapeutic termination of pregnancy or unexpected delivery of a nonviable infant. It is an emotional experience for the family and nurses. Investigators aimed to illuminate the experience of nurses caring for women experiencing a fetal loss and/or termination of pregnancy on a gynecological medical/surgical unit. The study used a qualitative, descriptive design approved by the Institutional Review Board. Semi-structured interviews were conducted with nine registered nurses, and transcripts were analyzed using constant comparison methods resulting in codes and themes by three investigators. The experience of nurses caring for women and infants during fetal loss and termination of pregnancy occurs throughout a continuum before, during, and after work. The experience is one of the layers, starting with emotions, sadness, and remorse in the center, followed by layers of attitude (respect and comfort) and action (communication). The foundation for these layers is teamwork, faith, and coping, surrounded by a box of uncomfortableness and distress. Nurses care for both the woman and infant during the termination of pregnancy and fetal loss, treating each with respect and comfort by communicating in both words and physical presence. Support between nurses with similar experiences provides a strong foundation that buffers the uncomfortable and distressing experience.

Background: Periodontitis, an inflammation that causes alveolar bone destruction, is caused by bacteria and aggravated by nicotine exposure and is therefore a disease that many smokers have. Antibacterial agents are essential for the rejuvenation process in periodontitis treatment; antimicrobial peptide (AMP) gel is a broad-spectrum antibacterial agent that is hardly cause bacteria resistance. Purpose: The objective of this study is to determine the effect of AMP gel administration on neutrophil and macrophage counts on periodontitis regeneration in nicotine-exposed rats. Methods: 24 Wistar rats were separated into four groups: nicotineexposed, non-nicotine-exposed, treatment and control. Rats with periodontitis were given AMP in the gingival line on days 1, 3 and 7 after having their mandibular central incisors ligated for 14 days to induce periodontitis. After AMP treatment, two groups of rats were collected randomly. Each group were decapitated, followed by treatment and histological examination with hematoxylin-eosin staining in the pathology laboratory to view neutrophils and macrophages. The asymmetric Kruskal Wallis test was used to analyse the data. Results: In mice treated with AMP, neutrophil counts on day 3 were lower than in distilled water (Aquadest) controls. The number of macrophages on day 3 was higher than that of the Aquadest control. Kruskal Wallis test results for neutrophils were p = 0.017 and for macrophages p = 0.01, where both test results had p < 0.05, there were significant differences between the neutrophil and macrophage groups. Conclusion: The administration of AMP effects on decreasing the number of neutrophils and enhancing macrophages in the periodontitis regeneration. in nicotine-exposed rats.

Published: June 2022

A educação em saúde é um campo desafiador, visto que o aprendizado prático deve ser transmitido para profissionais ainda inexperientes, sem comprometer a segurança dos pacientes. O uso da simulação em saúde vem crescendo progressivamente nas últimas décadas e promove o treinamento de habilidades técnicas e não-técnicas, com menor exposição de aprendizes a situações clínicas delicadas em um ambiente controlado e seguro. As atividades de simulação costumam ser acompanhadas de um feedback ou debriefing, que consiste em uma prática reflexiva interativa na qual se discutem as ações e o desempenho de uma atividade simulada. Metodologia: revisão narrativa de artigos da base de dados MEDLINE sobre técnicas de debriefing. Objetivos: descrever as diferentes abordagens de debriefing através de revisão da literatura. Resultados: Existem várias estruturas descritas de debriefing, com suas semelhanças e peculiaridades, sem que haja evidência de superioridade de alguma delas. Conclusão: A atividade simulada provê uma experiência concreta e autêntica, mas a análise, discussão e reflexão deliberadas a partir do evento são os principais componentes que estruturam o ensino prático eficaz. Não há uma melhor maneira de conduzir o debriefing, mas diferentes métodos que os facilitadores podem escolher conforme o contexto do cenário, bem como suas habilidades e preferências.

Objective: To explore the effect of dysregulation of epigenetic regulator EZH1 and EZH2 on the proliferation in MCL and the underlying mechanisms. Methods: In this study, we elucidated the role of EZH1 and EZH2 overexpression by immunohistochemistry and correlated them to clinical outcome in 41 MCL patients. Quantitative real-time PCR and Western blot were applied to confirm the level of EZH1 and EZH2 in well-characterized MCL cell lines which were compared to those of na B cells. Then we manipulated the expression of EZH1 and EZH2 in MCL cells using CRISPR/Cas9 system to directly investigate their functional roles in MCL. We also evaluated the effect of two small molecule selective inhibitors, EPZ005687 and UNC1999, on MCL cell proliferation, cell cycle distribution and apoptosis in vitro. Finally, we performed RNA-sequencing (RNA-Seq) and Chromatin immunoprecipitation (ChIP) assay to further gain insight into the underlying molecular mechanisms. Results: We found that EZH2 protein is overexpressed in approximately half of this cohort of MCL cases. More importantly, the overexpression of EZH2 is associated with poor OS in the patients. Nevertheless, simple EZH2 depletion in vitro has little impact on the viability of MCL cells, predominantly because of the consequent up-regulation of EZH1. Consistently, UNC1999, a dual EZH1/2 inhibitor, unlike the EZH2 selective inhibitor EPZ005687, exerts a potent inhibitory effect on MCL cells. Furthermore, we discover CDKN1C and TP53INP1 as the two important cell cycle regulators, the expression of which are repressed by EZH1/2 mediated epigenetic regulation and are restored by EZH1/2 dual inhibition. Conclusions: Our study suggests that EZH2 participates in the pathogenesis of MCL which may serve as a potential biomarker for prognosis prediction. The dual inhibition of EZH1/2 is a promising therapeutic strategy for MCL.
The Latest News for May 2022 All You Need to Know on Monkeypox
Authors: m dheeraj
Published: June 2022

Monkeypox virus was named so because of its detection in monkeys in 1958. It belongs to the same family as smallpox and chickenpox viruses. There had been numerous outbreaks of this malady initially in the African continent and other parts of the world. The simultaneous spread in nineteen countries in 2022 has raised some serious concerns.Monkeypox is no more a rare disease and has the potential for bioweapon use. We discuss the various ways to prevent its spread, treatment options available, diagnosis, and differentiation from other closely related diseases. We also discuss if the present outbreak could be a bioattack or if this disease is here to stay.The literature suggests that we can effectively manage Monkeypox because of the availability of drugs and vaccination against smallpox. There is also a need for active surveillance against the new resistant recombinant viral strains. The possibility of this outbreak being a bioattack seems remote, although there are questions about the transmission which still need to be answered.
Dynamics of Whole Virus and Non-structural Protein 1 (NS1) IgG Response in Mice Immunised with Two Commercial Tick-borne Encephalitis Vaccines
Authors: Salat Jiri , Strakova Petra , Ruzek Daniel
Published: June 2022

The presence of a non-structural protein 1 (NS1) in tick-borne encephalitis (TBE) vaccines and the possible induction of an NS1-specific immune response in vaccinated individuals remains a somewhat controversial topic. Previously, we detected the presence of NS1 in Encepur TBE vaccine by mass spectrometry and found the induction of NS1-specific IgG antibodies in mice vaccinated with FSME-Immun TBE vaccine. Here, in this follow-up study, we examined the dynamics and extent of the NS1-specific IgG response in mice vaccinated with these two vaccines in more detail and compared it with the IgG response to the whole virus (WV). Mice were vaccinated at two-week intervals with a total of six doses of each vaccine, and levels of IgG antibodies to TBE virus WV and NS1 were measured by ELISA after each dose. Both vaccines elicited a robust anti-WV IgG response after two doses. The Encepur vaccine did not elicit NS1-specific IgG even after all six doses. In contrast, FSME-Immun vaccine triggered production of NS1-specific IgG after four doses. The results indicate that FSME-Immun is the only vaccine that elicits an NS1-specific antibody response in mice. However, compared to WV-specific IgG, the NS1-specific response is weaker, and a higher number of doses is required to induce detectable levels of NS1-specific IgG antibodies.

Masons are often overlooked part of impact basins, but play an important role in revealing the lunar history. Previous study in masons were usually limited to gravity data. Few researches were reported on morphology features and chronology, which hampers the construction of a complete geological interpretation for the evolution of each mascons. We use multi source remote sensing data to identify the details characteristic of mascons. Result of topography, gravity and characteristic are combined to prove that a mason beside Copernicus crater is a buried peak-ring basin which is about 130km and 260km in diameter. The underground structure is of confirmed as 890m thick mare basalts by analyzing the spectral feature of the material in a geological outcrop called Copernicus H. Geology evolution analysis joint crater size-frequency distribution (CSDF) dating demonstrate that the buried basin impact event occurred in 3.6Ga. Then a hawaiian-style eruption in late Imbrian formed Sinus Aestuum Ⅰ Dark Mantling Deposit (DMD). Mare basalts filling in 3.4Ga. After that, ejecta from Copernicus impact event in about 820Ma and weathering processes cause the disappearing from lunar surface of the buried basin.

Published: June 2022

The present study shows a methodology for analyzing and designing a cylindrical packed-bed reactor considering stationary and dynamic models. The design comprises the reactor's stationary and dynamic governing differential equations for mass and heat transfer under multi-dimensional approaches. The results included simulation of concentration, temperature, and reaction rate profiles via the 1-D and 2-D differential equations solution with FlexPDE software. The analysis was complemented with a scaled 3-D dynamic model implemented in COMSOL Multiphysics. Both FlexPDE and COMSOL Multiphysics relied on the finite element technique to solve the governing differential equations. The simulated concentration and temperature profiles from both FlexPDE and COMSOL models were compared to experimental data gathered from literature (specifically from a Fischer-Tropsch process to produce low-molecular-weight hydrocarbons in a configuration of cylindrical packed-bed reactors). Simulated concentration and temperature profiles from the 2-dimensional dynamic model and the COMSOL model were in good agreement with the trend observed in experimental data. Finally, the predicted reaction rate profiles from the COMSOL model and the 2-dimensional dynamic model followed the temperature trend, thus reflecting the temperature dependence of the reaction.

Pathologies of the blood brain barrier (BBB) have been linked to a multitude of CNS disorders whose pathology is poorly understood. Cortical spreading depression (CSD) has long been postulated to be involved in the underlying mechanisms of these disease states, yet full understanding remains elusive. This study utilized an in vitro model of the BBB with b.End3 murine endothelial cells to investigate the role of CSD in BBB pathology by characterizing effects of the release of major pronociceptive substances on BBB functional integrity using TEER screening, transcellular uptake, and immunoreactive methods in concert with global proteome and phospho-proteomic approaches. Findings demonstrated relocalization and functional alteration to proteins associated with the cytoskeleton and endothelial tight junctions. Pathologic mechanisms induced by individual substances released during CSD were found to have unique phosphorylation signatures in phospho-proteome analysis, identifying Zona Occludens 1 as a possible pathologic “checkpoint” of the BBB. Utilizing these phosphorylation signatures, possible novel diagnostic methods may be developed for neurological diseases and warrants further investigation.

Work Accident Guarantee Program (JKK) is one form of welfare and legal protection for workers who experience work accidents. However, in fact, there are still many companies that do not register their workers in the Work Accident Guarantee Program (JKK) which was initiated by the Employment Guarantee Agency or commonly called BPJS Employment. Furthermore, the authors raise the formulation of the problem, namely: (1) What are legal sanctions against employers if they do not register their workers in the Work Accident Guarantee Program based on Chapter 4 of Government Regulation Number 44 of 2015. (2) How is the legal protection for workers/labourers who are not registered in the Work Accident Guarantee Program.

The research is a type of legal research using normative legal research methods which is analyze through statute approach, conceptual approach, and historical approach.

The result of this research shows that, Employers who do not register their workers in the Work Accident Guarantee Program (JKK) will receive administrative sanctions, either in the form of fines, written warnings, or not receiving certain public services. The rights of workers who experience work accidents both from the cost of transportation, care, and treatment, as well as wages for not being able to do work are the responsibility of the employer. In addition, since starting to work, the worker concerned can also register himself in the Work Accident Guarantee Program (JKK) and charge the employer with the collection of contributions.

Published: June 2022

The design of social media promotions is focused on one beverage brand, namely "Pour And Peace". "Pour And Peace" is a beverage brand originating from Pekanbaru City and has a good appeal among teenagers to the elderly. With the uniqueness of the drink that uses coffee beans typical of the Sumatran region and the visuals on the product, it is possible to promote the "Pour And Peace" product to strengthen the image and awareness of the target audience for local products. The “Pour And Peace” product has its own uniqueness with its visual appearance that looks like a drink containing alcohol in its packaging. But actually this drink is coffee beer or so-called coffee soda. "Pour And Peace" itself makes the design more unique because the main target market is young people or teenagers. The use of photography is very possible to be used as a way to promote "Pour And Peace" products, by taking pictures made more expressive, with product photo techniques, still life, angel placement, composition and so on. This design is made using a marketing design method that identifies product data and marketing data which are finally analyzed. After the identification process, the author determines the synthesis and design concept which consists of media planning and creative planning so as to produce a design concept concept. The final design results are determined in the form of promotional media in the form of photos and videos published on social media. The results of this design are expected to introduce coffee beer products

Japan sea sediments consist of various detrital materials of eolian and riverine origin. Understanding the provenance of eolian dust is vital for reconstructing the variability of wind patterns and monsoons in the past. New and complete eolian accumulation rates from Taklimakan, Gobi, and Ordos are reconstructed at Integrated Ocean Drilling Program (IODP) Site U1425 in the Japan Sea using parallel factor (PARAFAC) endmember modeling. Our results show that Taklimakan dust is dominated by the silt fraction, while Gobi dust is dominated by the clay fraction, and they are controlled by the relative contributions of different pathways of dust transport, such as the westerly winds and East Asian winter monsoon (EAWM). Clay-size dust from Gobi increased during three periods, late Miocene global cooling (LMGC), intensification of Northern Hemisphere Glaciation (iNHG), and mid-Pleistocene Transition (MPT), which reflected increased EAWM winds associated with global cooling and glaciation. Taklimakan became the major dust contributor to the Japan Sea sediments during the warmer climate periods in the latest Miocene to early Pliocene and the Late Pleistocene, where westerly wind activity dominated eolian transport. Dust from Ordos increased greatly 0.95-0.85 Ma due to enhanced Asian aridification since 2 Ma in Northwest China. Detrital flux from Japanese islands suggests that the East Asian summer monsoon (EASM) was stronger 9.6-8 Ma and weakened from 8 Ma to the Pleistocene.

To ensure the safe and efficient development of deep and ultradeep natural gas exploration, it is very important to solve the gas channeling problem of cementing annulus cement slurry in a high-temperature environment. In particular, how to ensure that the cement slurry still has a certain strength, good microstructure, and low permeability in the well are the key points. Based on the current high-temperature and deep well conditions, this paper conducts tests on the microstructure, pore size distribution, and permeability of cement slurry samples with different hydration times. The study found that before the initial setting, the cement slurry gradually changed from a liquid state to a “skeleton-pore” solid medium state, and the permeability of the cement slurry gradually decreased and the rate of decrease gradually accelerated. On the whole, conventional cement slurry has good channeling channel and large permeability before the initial setting. Second, the ability of different antichanneling agents to improve the performance of the cement slurry, the period of action, and the mechanism of action are different. Therefore, to further fully consider its influence on the comprehensive performance of the cement slurry in actual use, it is better to use different antichanneling agents with each other, which can significantly improve the gas channeling resistance and cementing quality of high-temperature cementing slurry system.
