Assessment Framework for Recognizing Clinical Deterioration in Patients With ACS Undergoing PCI
Authors: White Kevin , Currey Judy , Considine Julie
Published: August 2021

Topic

Patients with acute coronary syndrome undergoing primary percutaneous coronary intervention are at risk of clinical deterioration that results in similar general signs and symptoms regardless of its cause. However, specific causes and forms of clinical deterioration are associated with key differences in assessment findings. Focused clinical assessments using a modified primary survey enable nurses to rapidly identify the cause and form of clinical deterioration, facilitating targeted treatment.

Clinical Relevance

Clinical deterioration during percutaneous coronary intervention is associated with increased mortality and morbidity. Previous studies identified nursing inconsistencies when recognizing clinical deterioration, with inconsistent collection of cues and prioritization of cues related to cardiac performance over more sensitive indicators of clinical deterioration.

Purpose of Paper

To describe a framework to help nurses optimize physiological cue collection to improve recognition of clinical deterioration during periprocedural care of patients undergoing percutaneous coronary intervention for unstable acute coronary syndrome.

Content Covered

Literature analysis revealed 7 forms of clinical deterioration in patients undergoing percutaneous coronary intervention: coronary artery occlusion, stroke, ventricular rupture, valvular insufficiency, lethal cardiac arrhythmias, access-site and non–access-site bleeding, and anaphylaxis. Evidence for the pathophysiology, incidence, severity, and clinical features of each form of clinical deterioration is identified. A framework is proposed to help nurses conduct highly focused patient assessments, enabling prompt recognition of and response to the specific forms of clinical deterioration that occur in patients undergoing percutaneous coronary intervention.

The vertical ladder-based protocols contribute to the NMJ junction's adaptations, and when combined with and without load, can be potentiated. The present study aimed to investigate postsynaptic regions of the biceps brachii muscle in adult male Wistar rats submitted to different vertical ladder-based protocols (Sedentary - S; Climbing - C; Climbing with Load - LC and Combined Climbing - CC). The protocols (C, LC, CC) were performed in 24 sessions, 3 x/week, for 8 weeks. The myofibrillar ATPase analysis showed an increase in cross-sectional area (CSA) of the muscle fibers Type I in all trained Groups; Type II in C and LC and reduction in CC; Type IIx higher in all trained Groups. In the postsynaptic cleft, the stained area presents smaller in Groups C, LC, and CC; the total area showed smaller than LC and higher in C and CC. The stained and total perimeter, and dispersion showed a reduction in C, LC, and CC, higher maximum diameter in Groups C and CC, and decreased in LC. Regarding the postsynaptic cleft distribution, the stained area presented a decrease in all trained Groups. The integrated density presented higher principally in CC. The NMJ count showed an increase in all trained Groups. We concluded that the vertical ladder-based protocols combined contributed to the postsynaptic region adaptations.

Colorectal cancer (CRC) is a major public health threat. Therefore, CRC screening uptake has been a focus with the established precancerous lesion and the strong association of early detection with staging and survival of the disease. However, CRC screening is relatively low in many countries. This article briefly discussed the current situation of CRC, recommendations, and current uptake of CRC screening in various countries. Besides that, this article also highlights the potential factors that help to predict the CRC screening uptake worldwide. Identification of those factors could guide policymakers to develop an effective strategy to improve the CRC screening uptake and ultimately improve the health outcome of the population.

Published: August 2021

With improvement in the outcomes of chemotherapy, the management of late effects of chemotherapy is an increasingly important concern in patients with osteosarcoma. However, the risk factors for late effects on kidney function are not clear. We report seven cases of osteosarcoma, including three patients with severe or recurrent drug-induced acute kidney injury, who were diagnosed with tubulointerstitial nephritis after the treatment of osteosarcoma. Although late renal effects are considered to be dose-dependent, they are not invariable with the same protocol. The severity and frequency of acute kidney injury following chemotherapy might have influenced the occurrence of renal late effects.
Catheter-related Blood Stream Infections among Children on Hemodialysis over 7 Years
Authors: Kumar Gurinder
Published: August 2021

Patients with end-stage kidney disease frequently require hemodialysis (HD) through central venous catheters (CVCs) as a bridge to renal transplantation. However, longevity of CVCs is affected by the occurrence of CVC-related bloodstream infections (CVC-RBI). This retrospective study evaluated the outcomes of CVCs inserted for HD, with specific attention to rates and etiology of CVC-RBI. Over 7 years between January 2010 and December 2016, 39 patients, aged 2–15 years, were admitted for HD for ESRD in the Department of Pediatric Nephrology, Sheikh Khalifa Medical City, Abu Dhabi, UAE. The most etiology for ESRD was renal dysplasia (28.2%). Tunneled cuffed CVC was inserted most commonly in the right internal jugular vein (40.2%). The most common reason for change of CVC was CVC-RBI (28.9%). The estimated rate of CVC-RBIs was 1.72/000 CVC days. Staphylococcus aureus was the most common (28.6%) etiology. CVC longevity was significantly influenced by the occurrence of CVC-RBI (P < 0.001), and the rates of CVC-RBI were significantly different between patients with less or more than 200 CVC days (P = 0.002). Most patients either continued on HD (48.7%) or underwent kidney transplantation (28.2%). This study highlights that rates of CVC-RBI were low but were associated with prolonged CVC use.

Published: August 2021

Henoch–Schönlein purpura (HSP) nephritis (HSPN) and immunoglobulin A (IgA) nephropathy (IgAN) are related conditions that may be encountered sequentially in the same patient, are described in twins, and have common biological and pathological basis. The clinical features as well as the spectrum of severity at presentation vary significantly among patients. Here, we report a girl who first presented with acute glomerulonephritis and biopsy evidence of acute diffuse proliferative IgA nephritis with crescents, and 5 years later, she developed HSP and proteinuria. Such delayed appearance of cutaneous manifestations after initial renal involvement is unusual, though reported previously. This presentation stresses the importance of long-term follow-up of patients with HSPN and primary IgAN.

Management of acute gastroenteritis (AGE) includes treatment of underlying infections as well, since AGE may be an atypical presentation of urinary tract infection (UTI). The present study was planned to study the prevalence of UTI in children presenting with AGE. Two hundred consecutive patients presenting with AGE at 2 months to 4 years of age to one center's emergency department over 1 year were evaluated for UTI. Of 200 patients, 103 were male and 97 were female. One patient had infectious diarrhea. One hundred and forty-one (70.5%) patients were febrile, 63 (31.5%) patients had mild dehydration, 107 (53.5%) patients had moderate dehydration and 30 (15%) patients had severe dehydration. Twenty-five (12.5%) patients had pyuria. Fifteen (7.5%) patients had positive urine cultures. One of these (6.7%) patients had a history of UTI in the mother and 5 (33.3%) patients reported a history of UTI in their siblings. Of 15 patients with UTI, 13 (86.6%) were girls; 5 (38.4%) had labial adhesions. Escherichia coli and Klebsiella were isolated in 4 and one cases in urine culture, respectively. UTI underlies 7.5% of children presenting with AGE.
The growing international relevance of Ambiente & Água according to Scopus CiteScore results
Authors: Dias Nelson Wellausen
Published: August 2021

The Ambiente & Água Journal has adopted strategies in recent years to increase its relevance within the international scientific community. The results of CiteScore, recently released for the triennium ending in 2020, indicate that the journal’s strategies are starting to show good results. Evidence of an increase in the proportion between the number of citations received versus the number of documents published is corroborated by the impact indicators from other sources, such as the Scimago Journal Rank (SJR) and Leiden University’s Centre for Science and Technology Studies (CWTS) Impact per Publication (IPP). Also positive is the fact that the journal's impact is increasing even with the increase in the number of papers published, contrary to the strategy adopted by some journals that limit the number of papers in order to increase the journal's impact.
Heaven, hell, and saving souls: Were we always wrong?
Authors: Verster Pieter
Published: August 2021

Is the Bible clear on heaven, hell, and eternity? This question is important for the mission of the church. In recent books, N.T. Wright challenges the concepts of heaven and hell and the saving of souls for eternal heaven or the proclamation of judgement to those who are lost. Although his view is one of critical realism, which differs substantially from Bultmann’s demythologizing of the Bible as viewpoint, there are some similarities. Hans Küng also has some questions regarding traditional views on eternity. Bram van de Beek, however, explains that it is necessary to mention that this world is not our abode. In discussing biblical texts such as many parables and many of Paul’s utterances, one must regard the references to eternal life and the reality of heaven and hell as essential in the proclamation of the gospel. God’s grace is, however, much more glorious and encompassing than his wrath.
Management decision-making in the transition of a multinational company’s internationalisation strategy
Authors:   , Gehrlein Mario
Published: August 2021

In a globalized world economy, it is more beneficial for companies to have international activities because a larger group of customers can be served (Hollensen, 2017). As the business environment is continuously evolving (e.g. through enhanced transport systems), international active companies need to constantly investigate whether their strategy for an international activity (e.g. working with a local distributor) is the most appropriate or not and if not, to efficiently switch to a new market strategy (mode switching). This decision-making process of mode switching is considered as critical for companies since finding the most appropriate strategy for an international activity results in maximizing the profit of companies (Sachse, 2010). A literature review process combined with a qualitative thematic analysis of the selected studies have shown that within multinational companies (MNC) there can be multiple simultaneous switching processes because MNC have a global network of several international activities (Rezende, 2006; Hollensen, 2017). These simultaneous decision-making processes can be connected within the network of the MNC and can impact each other (interdependencies). One example of interdependence is that the used human resources for one process are only available for a limited extent of a simultaneous decision-making process (Rezende, 2006; Asmussen et al., 2009). Ignoring the interdependencies of this network within MNC can result in increasing complexity, costs and not using synergistic effects to raise the efficiency within MNC (Rezende, 2006; Asmussen, 2009). Using a single case study approach from a phenomenological philosophical position, the mode switching process of one MNC has been investigated by conducting 15 semi-structured interviews with managers of the decision-making process and by documentation reviewing. This detailed and in-depth analysis has led to the outcome of a new process model which illustrates three set-ups for the decision-making process of mode switching within MNC including the interdependencies existing between multiple simultaneous mode switches.

In some cases, there are problems associated with the compression and enlargement of images. The use of splines is quite effective in some cases. In this paper, a new image compression algorithm is presented. The features of increasing the size of an image when using local polynomial or non-polynomial splines are considered. The main method for enlarging an image is based on the use of splines of the second and third order of approximation. Polynomial and trigonometric splines are considered. To speed up the process of enlarging the image, we used the parallelization techniques
Application of the Kinesio® Taping Method for a Child with Hypotonia: A Pilot Case Study
Authors: Griffin Margaret , McGuff Christina , Willse Nicole , Twaddell MacKenzie , Shin Julia
Published: August 2021

Background: This study explored the application of the Kinesio® Taping (KT®) method in conjunction with traditional occupational therapy (OT) intervention for a child with hypotonia. Specifically, differences in functional hand outcomes (manual dexterity and grasp pattern) were examined between the sessions with and without the application of the KT® method.

Methods: A 9-year and 5-month-old male subject, at the time of enrollment, diagnosed with hypotonia, global developmental delay, and autism spectrum disorder participated in the study. A single-subject alternating treatment design was employed. A total of 14 OT sessions were conducted across baseline (n=3), alternating treatment (n=8), and replication (n=3) phases. During the alternating treatment phase, the subject was randomly applied the KT® method in four out of the eight OT sessions. At the end of each session, the participant was administered standardized assessments.

Results: There were no statistically significant differences observed in functional hand outcomes across the baseline, alternating treatment, and replication phases. There were no statistically significant differences observed in manual dexterity and grasp pattern between the sessions with and without the application of the KT® method.

Discussion: The results from the study replicated the mixed outcomes reported in the efficacy of the KT® method in addressing functional hand outcomes; OT practitioners are recommended to consider the KT® method as an auxiliary intervention modality. Future research involving the KT® method can consider ways to better control for the confounding variables noted in the current study including the novelty effect, subject’s comorbid conditions, and number and length of sessions allotted across the baseline, alternating treatment, and replication phases.

Authors: Chauhan Gagandeep , Kumar Vivek
Published: August 2021

Timetable scheduling is a problem that concerns every teaching institution. Every semester or year a new timetable must be produced to take account of faculty, student and course changes causing a necessarily large amount of work. All institutions face a considerable number of difficulties especially before the start of academic semesters in colleges due to the increased number of students and courses. Also, visualizing the timetable needs drastic amount of work like to print them on papers and display it then to its respective classes, that too in colleges need to be secured since it got snatched away by the students there. And timetable updation require to follow full steps as followed during its creation in traditional paper-based method but here using timesync, it makes everything so smooth that it need to only update it with its user-friendly UI and no need to follow other steps as in orthodox method. The main objective of this study is to develop a web-based application for timetable scheduling and visualizing for schools and colleges. However, some work and studies still need to be done to make this system further smart and consistent as described in the recommendations section.

Published: August 2021

Os traumatismos faciais no cenário da guerra são um fator importante de incapacidade funcional e estética. Devido a localização da face no corpo e a falta de equipamento de proteção adequado, lesões são comuns nesta região. A evolução do padrão destas lesões acompanhou a mudança na sua etiologia ao longo dos últimos anos. Portanto é importante identificar o tipo de armamento empregado, assim como realizar a prevenção e tratamento otimizado dessas lesões. O objetivo deste trabalho foi identificar a etiologia e incidência destes tipos de lesão através de uma revisão integrativa da literatura. Foram utilizadas plataformas de pesquisa científica (PUBMED, Scielo e ScienceDirect) e análise das publicações relacionadas a este tema. Podemos concluir com base nos dados pesquisados que as lesões bucomaxilofaciais no cenário da guerra apresentam relevante incidência e sua principal etiologia foram os estilhaços/explosivos. Dessa forma, podemos destacar o importante papel do cirurgião bucomaxilofacial no contexto da saúde operativa.

O Serviço de Saúde reúne os militares que executam atividades e tarefas destinadas a promover, aumentar, conservar ou restabelecer a saúde física e mental dos recursos humanos da Força Terrestre. Por sua natureza, o suporte do Serviço de Saúde do Exército é contínuo, flexível e adaptado a cada situação de emprego e à natureza da força apoiada. O objetivo do presente trabalho foi desvelar sobre o impacto da habilitação de militares da linha bélica em Atendimento Pré-Hospitalar, na sobrevivência do militar acidentado. Foi realizada revisão sistemática do tema na literatura, utilizando as bases Biblioteca Virtual em Saúde (BVS), Lilacs, Scielo, Medline (Pubmed), Cochrane Database of Systematic Reviews, Health Evidence e EBUSCA (bibliotecas do Exército Brasileiro), além do Google Scholar (literatura cinzenta). Foi evidenciado na revisão que existem, inclusive no Brasil, variadas entidades médicas especializadas em APH tático, algumas formadas inclusive por ex-combatentes de outros países ou militares que atuaram com a necessidade de técnicas especiais de primeiros socorros, com cursos de especialização que atendem a empresas de segurança, órgãos públicos e público interessado com a finalidade de difundir a mentalidade do TCCC no cenário atual, mostrando que não há falta de fontes para formação de uma doutrina do tipo no Exército Brasileiro. O APH é a assistência primária, das vítimas de trauma e disfunções clínicas, recomendada em diversos países e no Brasil. Os motivos clínicos de assistência durante as ações realizadas pelas equipes de APH, no meio militar não são habituais, certamente, pela saúde potencial dos militares, que deve ser levado em consideração na higidez dos seus quadros. Observou-se ainda, o fato de o efetivo ser constituído por militares mais jovens com vigor físico único para o cumprimento das missões. O trauma, assim como as causas clínicas, é minimizado, pela capacitação das tropas, e implemento fiel dos regulamentos e normas de segurança nas atividades militares, desta forma, evitando a ocorrência de eventos adversos. Desta forma, a capacitação dos militares da linha bélica é de suma importância para a efetiva implantação do APH no âmbito do Exército Brasileiro. Este aspecto possibilita ainda, um sistema mais fluido e alivia o atendimento em alguns setores mais especializados. Sob esta ótica, outro fator a ser considerado é a complexidade do treinamento das equipes de APH, exigindo conhecimento técnico especializado para sua execução, e também provimento de equipamentos (ambulâncias, insumos, etc..) para a execução das missões, que deve ser coberta de grande importância para que o APH seja eficiente no EB.

A preservação da saúde dos militares nos diversos cenários de operações é essencial para que a tropa esteja em condições integrais para atuação. Essa atividade, denominada atualmente como Proteção à Saúde da Força, engloba vários âmbitos, dentre os quais se destacam: controle de enfermidades infecciosas e zoonoses, gestão de resíduos e gerenciamento de animais sinantrópicos, imunização e quimioprofilaxia, proteção à água e aos alimentos e inteligência em saúde. Apesar destes vários âmbitos, ainda é escassa a literatura sobre as diversas tarefas que comporiam a atividade. Desta maneira, o presente estudo visou levantar estas tarefas através da aplicação de questionários entre especialistas, com objetivo de contribuir para a formulação de abordagens para o treinamento e desenvolvimento de habilidades de proteção à saúde da Força nos cenários de operações militares de campanha. Para isso, foram produzidos questionários eletrônicos, a serem respondidos por especialistas nas áreas pertinentes, sobre esses cinco eixos. No total, foram abordadas 46 tarefas que seriam fundamentais para desenvolver tal aspecto da proteção à saúde, 10 pontos doutrinários a serem seguidos, bem como diversas atividades que deveriam ser realizadas em nível operacional e estratégico para adestramento e desenvolvimento de uma cultura preventiva. A importância de tais ações fica evidente no elevado índice de baixas por doenças infectocontagiosas preveníveis no curso de operações militares ao longo da História. É fundamental que sejam desenvolvidas políticas e estratégias consistentes para a proteção à saúde da Força Terrestre.

Responden penelitian ini terdiri dari siswa kelas VIII berjumlah 24 anak yang diperoleh dari hasil penjaringan siswa sebanyak 300 anak. Pengumpulan data dilakukan dengan observasi, tes prestasi belajar dan dokumentasi. Metode dalam penelitian ini menggunakan dua siklus, yaitu siklus pertama dan siklus kedua. Masing-masing siklus terdiri dari dari perencanaan, tindakan, observasi dan refleksi. Pda setiap siklus dilaksanakan dalam dua kali pertemuan. Karena situasi pandemi covid, siklus kedua dilaksanakan melalui zoom meeting/ layanan jarak jauh. Adapun diskusi kelompok dilaksanakan cukup beranggotakan 2 anak melalui whatsApp /video call. Analisa data statistik penelitian ini menggunakan rumus t-test untuk menguji perbedaan hasil pretest dengan postest. Kesimpulan penelitian ini pelaksanaan layanan bimbingan klasikal melalui metode problem-based learning optimal serta dapat mengatasi perilaku bullying. Hal itu terbukti dari perolehan skor rata-rata post test siklus pertama dengan kedua mengalami penurunan -0,076. Data yang lain, sebelum ada tindakan ada 19 anak hampir sering sekali melakukan pembullyian, 3 anak sering dan 2 hampir sering melakukan pembullyian. Setelah mengikuti layanan bimbingan klasikal melalui model problem-based learning terdapat 12 anak sama sekali tidak melakukan pembullyian, 3 anak pernah dan 9 anak kadang pernah melakukan pembullyian. Selanjutnya rata-rata nilai diskusi kelompok siklus pertama dengan siklus kedua mengalami peningkatan 13,75. Sedangkan rata-rata nilai individu siklus pertama dan siklus kedua juga meningkat 11,46.

DESIGN AND OPTIMIZATION OF PCM-AIR COLD ENERGY STORAGE DEVICE TO BE USED FOR PEAK ELECTRICITY SHAVING
Authors: TÜRKAKAR Göker
Published: August 2021

Parametric analysis and dimensional optimization study for the melting process of the phase changing material placed in cold energy storage devices have been conducted. Phase changing material, PCM, is used to store the cold energy. A cross-flow tubular PCM-air heat exchanger is used. An electricity peak shaving for a summer day in Antalya for 5 hours (10:00-15:00) is aimed. The cooling load of a room (33 m2) in Antalya is taken as a reference value. A minimum cooling load of 2850 W is supplied throughout 5 hours to maintain the building's comfort temperature. Contrary to the studies handling air velocity constant, it is varied during melting in the present study to satisfy the minimum cooling load. The melting process is analyzed using a numerical model. A computational algorithm is implemented in MATLAB environment. The numerical model is validated for the same conditions and the dimensions with an analytical model presented in the literature. A transient analysis has been employed, and the problem is discretized for the time and space domain. A dimensional optimization algorithm is employed. A parameter “performance ratio/ cooling index”, the ratio of total cooling to fan energy consumption, is defined. Spacing between the tubes giving the maximum performance ratio is sought for aligned and staggered tube bank arrangements using this algorithm. The best performance ratio is obtained at 0.2 m/s initial velocities for both arrangements. In addition, the effect of sizing/arrangement of the tubes, PCM mass, and thermal conductivity of the PCM on the melting characteristics is investigated. As a result of increasing the thermal conductivity from 0.2 W/(m·K) to 0.6 W/(m·K), the performance ratios are raised 4.58 and 3.52 times for aligned and staggered orders, respectively. It is calculated that 10 kg PCM can be saved thanks to enhancing the thermal conductivity of the PCM.
