Deltakelse, prosess og produkt: Kreativitet i en skapende teknologimediert samarbeidsprosess i barnehagen
Authors: Undheim Marianne
Published: February 2022

I denne artikkelen utforsker jeg begrepet kreativitet i en skapende prosess med digital teknologi i barnehagen. Problemstillingen er: Hva kjennetegner en skapende teknologimediert samarbeidsprosess der en gruppe barnehagebarn (4–5-åringer) og en barnehagelærer lager en digital bildebok sammen? Studien er en kvalitativ casestudie, og datamaterialet består av videoobservasjoner av prosessen og det ferdige produktet, en digital bildebok. Som teoretisk rammeverk for analysen bruker jeg begrepene mulighetstenkning av Anna Craft og distribuert kreativitet av Keith R. Sawyer. Analysen viser at den skapende teknologimedierte samarbeidsprosessen kjennetegnes av at barna og barnehagelæreren på ulike måter engasjerer seg i mulighetstenkning og sammen utforsker nye muligheter. Kreativiteten distribueres mellom deltakerne, aktivitetene og artefaktene, og prosessen kan karakteriseres som et eksempel på en kreativ teknologimediert samarbeidsprosess. Ved å ta utgangspunkt i egne tanker og ideer skaper barna og barnehagelæreren sammen en ny kulturressurs; de lager et produkt som er nytt, originalt og meningsfylt for dem. Analysen viser også at for å forstå helheten i barns kreative samarbeidsprosesser, er det viktig å inkludere både prosessen og produktet. Artikkelen bidrar med kunnskap om kreativ og skapende bruk av digital teknologi sammen med grupper av barnehagebarn, som er sentralt for både praksisfeltet og barnehagelærerutdanningen.
English abstract
Participation, process, and product: Creativity in a collaborative technology-mediated creation process in kindergarten
In this article I explore the concept of creativity in a creation process with digital technology in an early childhood education and care institution (kindergarten). The research question is as follows: What characterises a collaborative technology-mediated creation process in which a group of kindergarten children (age 4-5 years)and a kindergarten teacher create a digital picture book together? The study is a qualitative case study, and the empirical material consists of video observations of the process and the finished product, a digital picture book. As the theoretical framework, I use the concepts of possibility thinking and distributed creativity. The analysis shows that the participants engage in possibility thinking in different ways during the creation process and explore new possibilities together. I interpret the process as a creative collaborative technologymediated process in which creativity is distributed between the participants, the activities, and the artefacts. By drawing on their own thoughts and ideas, the participants create a new cultural resource; they create a product that is new, original, and meaningful to them. The article contributes with knowledge of creative useof digital technology together with groups of young children, which is central to the field of practice and the kindergarten teacher education.

Published: February 2022

Regardless of how the public perceives agriculture, the reality is that today's agriculture industry is more data-driven, precise, and sophisticated than ever before. The rapid rise of Internet-of-Things (IoT)-based technologies has transformed practically every industry, including "smart agriculture," which has moved away from statistical to quantitative techniques. Smart agriculture allows for more efficient fertilizer use and less water waste. The goal of the smart agribusiness research is to create a dynamic and emotionally supportive farm management network. IoT is being used in agriculture to learn about the agricultural field by using sensors for field monitoring and control. Sensors are used to acquire a better understanding of the crop field for monitoring, field control, and other applications. We'll look at how Internet of Things architectures aid farm fields in this research. The entire Internet of Things (IoT) Solicitations in Agriculture, as well as how they work, are provided. According to the report, IoT can also be used to fill in gaps in agriculture. Technology scalability should be encouraged without jeopardizing existing infrastructures functionality. The current state of Internet of Things (IoT) solicitations in agricultural, as well as future projections, are discussed in this article.

AUKUS: The Changing Dynamic and Its Regional Implications
Authors: Cheng Manqing
Published: February 2022

A historic security deal was announced on 15 September 2021. The strategic partnership amalgamating the United States, the United Kingdom and Australia is contrived to share advanced defence know-how and equip Australian forces with the nuclear-powered submarines. Attentions mount to the partnership’s ultimate purpose and implications for other countries. France expressed fury over its loss of the lucrative submarine deal by the scuppered pact. China sees itself as the target of the new grouping. Although reactions vary, the ASEAN generally views the enunciation of AUKUS as deteriorating the geopolitical situation in the region. Why have the three member states initiated such trilateral defence agreement? This article analyses that the audacious enlistment marks a shift in US global strategy, redistributing its forces by empowering its allies to strengthen military capabilities around the Indo-Pacific. It represents Australian eager to project power up to shape the security environment more in Australia’s favour, enhance its status and influence within the American alliance system and heighten its Anglophone identity. This article contends that the advent of a new inner Anglosphere core has disturbed the regional order by potentially escalating arms race, increasing regional tensions and undermining relevant institutions of non-proliferation of nuclear weapons.

Published: February 2022

Schoolteachers and college instructors from around the world can create or join special Facebook pages (FPs), groups, or clubs for ESL teachers for free. Those FPs are online learning communities that provide opportunities for in-depth peer-to-peer interaction, communication, and support. This study aims to give examples of FPs for ESL teachers; identify the kinds of topics and issues posted about the teaching and learning of English as a second/foreign language; find out whether there are special ESL Teachers’ Facebook Pages (TFPs) that focus on remote teaching and learning during the Covid-19 Pandemic; whether there are difference in the topics posted in TFPs before and during the Pandemic; and to explore the advantages and shortcomings of TFPs, and their role in teacher’s professional development before and during the Covid-19 Pandemic as perceived by a sample of ESL teacher who are members of those pages. 2500 posts from 75 ESL TFPs were analyzed. It was found that 12% are general TFPs, 42% target ESL teachers in specific countries, 16% are devoted to recruitment and job announcements, 38% are theme-based, and 22% focus on online/virtual and home-based teaching. The topics that teachers post in the TFPs, teachers’ views of the benefits and shortcomings of joining TFPs, and the role of TFPs in their professional development are reported in detail.

Published: February 2022

Probiotics are live microorganisms added to food products to confer health benefits such as gut health, cancer protection and improved immunity when consumed. Fruits juices are considered as potential channels for delivering probiotics as they contain essential nutrients and low pH suitable for the growth of probiotics. The study was undertaken to formulate, process and characterize fermented probiotic mango fruit juice using three different mixed lactic acid bacteria cultures: Abt-5® culture (Streptococcus thermophillus, Bifidobacterium and Lactobacillus acidophilus); Fiti® culture (Lactobacillus rhamnosus GR-1) and Yo-mix® culture (Streptoc.occus thermophillus and Lactobacillus delbruikii ssp bulgaricus). The viability of the cultures was also assessed. The mango juice was formulated using mango pulp to water ratios of 100:0, 25:75, 50:50 and 75:25 (v/v) and adjusted to 17° brix by adding cane sugar. The formulated mango juices were pasteurized at 90 °C for 1 minute and cooled to 10 °C. Sensory evaluation was carried out to determine the most preferred formulation of the fruit juice before fermentation. The preferred mango juice samples were cooled to 402 °C and incubated with the three different mixed bacteria cultures (1 g/l) for 0, 12, 16, 24, 36, 48 and 72 hours. The final product stored at 4 °C. Analysis for sensory evaluation, culture viability, pH, total soluble solids (TSS) and total titratable acidity (TTA) was done. The 50:50 ([mango pulp: water) mango fruit juice formulation was significantly different (p<0.05) from the other samples in consistency and was rated the best in overall acceptability. There was general increase in cell count in all cultures with mango juice fermented with Lactobacillus rhamnosus GR-1 for 48 hours recording the highest viable cell count of log10 9.14 CFU/ml. Highest pH decrease was observed in 50:50 formulation with significant (p<0.05) increase in TTA from 0.15% to 0.69% using Lactobacillus rhamnosus GR-1 within 72 hours. Subsequently, the TSS decreased from 17° brix to 14.47° brix. The study showed that the three mixed were able to utilize nutrients present in the formulated mango juice during fermentation as demonstrated by decrease in pH and TSS. The study therefore recommends that further research should be done on the probiotic fermented mango juice to determine the change in physco-chemical characteristics and culture viability during storage.

Yoghurt is a popular probiotic milk product. Coffee flavoured yoghurt was developed to enrich the product with functional properties and help enhance local coffee consumption. The aim of the research was to study potential interaction of polyphenolic compounds present in coffee extract on the viability of lactic acid bacteria, yeast and moulds and, functional properties of coffee flavored yoghurt. Coffee flavoured yoghurt was prepared by adding coffee flavour extract to the yoghurt in varying amounts; 0.0%, 0.1%, 0.2%, and 0.3%. Treatment 0.0% was the control. A complete randomized design (CRD) was used, in which yoghurt was divided into 4 treatments in triplicate and was randomly assigned to 12 experimental units. The sampling for analysis was done at intervals of one week for 28 days from day one. Microbial analysis was done using standard AOAC 2016 method using MRS and PDA media and results were reported as CFU/ml of the coffee flavored yoghurt. Functional properties were determined by evaluation of total polyphenols and antioxidant activity using the Free radical scavenging activity by DPPH method and Folin ciocateau method. Data was analyzed by use of ANOVA, means separated by LSD at p<0.05 level of significance. From the findings, lactic acid bacteria in coffee flavoured yoghurt ranged between 3.7x107-1.09x108CFU/ml. Yeast and moulds ranged between 3.6x101-8.33x100 CFU/ml. TPC between 5.76±0.4-97.89±0.6mgGAE/ml while Antioxidant properties ranged from 15.82±0.9- 68.55±0.9 % DPPH. There were significant differences between coffee flavoured yoghurt and the control on the functional properties. In conclusion, addition of coffee flavour extract into the yoghurt improved the keeping quality of the yoghurt while maintaining its probiotic potential. More studies on addition of natural coffee flavour into other milk products are recommended.
Factors Influencing Labour Turnover Intentions in Non-Governmental Organization: Insights from Christian Social Service Commission (CSSC) in Dar es Salaam
Authors: Bangi Yustin Ignas , Mgeni Prisca Levi
Published: February 2022

Managing labour turnover is critical for any organization sustainability and competitiveness. In the past, turnover was higher in government organizations as compared to non-Governmental Organizations. Currently however, non-Governmental organizations are facing difficulties to retain good performers, experienced and well trained employees due to high turnover. This study attempted to assess factors influencing labour turnover intentions in non-Governmental Organizations by taking the case of the Christian Social Service Commission (CSSC) in Dar es Salaam. Specifically, the study sought to assess how work-related factors, organization factors and personal factors influence labour turnover intentions at CSSC. A case study design and quantitative approach were employed in this study. Data was collected from 80 employees through standardized questionnaire, and both descriptive and inferential statistics procedures were applied in data analysis. The research revealed that organization factors and work-related factors moderately influence turnover intentions, whereas the personal factors had no significant influence. In this respect improving on salaries, fringe benefits, personal career advancement opportunities, involvement in decision making, friendly organization policies, job securities to name a few will scale down turnover intensions. However, further studies can be carried out including more variables than those assessed in this study to reveal factors affecting labour turnover intentions.
Reading the Club as Colonial Island in E.M. Forster’s A Passage to India and George Orwell’s Burmese Days
Authors: Crane Ralph
Published: February 2022

This paper examines the “island effect” in two enormously influential colonial fictions published in the final decades of the British Empire in India. Through a detailed analysis of the Club scene in Forster’s A Passage to India (1924) and Orwell’s pervasive use of the Kyauktada Club in Burmese Days (1934), this paper brings critical focus to the phenomenon of the Club in British India. It explores the way the Club functions as an ‘island’ microcosm within a larger framework of colonial isolation, and the way intimate colonial relations prevail within its walls and sustain an isolated community which fears for its survival outside its enclosing border.
Envisioning the archipelago

Published: February 2022

Certain limitations arise from the persistent consideration of two common relations of islands in the humanities and social sciences: land and sea, and island and continent/mainland. What remains largely absent or silent are ways of being, knowing and doing—ontologies, epistemologies and methods—that illuminate island spaces as inter-related, mutually constituted and co-constructed: as island and island. Therefore, this paper seeks to map out and justify a research agenda proposing a robust and comprehensive exploration of this third and comparatively neglected nexus of relations. In advancing these aims, the paper’s goal is to (re)inscribe the theoretical, metaphorical, real and empirical power and potential of the archipelago: of seas studded with islands; island chains; relations that may embrace equivalence, mutual relation and difference in signification.
Autonomy Initiatives and Quintessential Englishness on the Isle of Wight
Authors: Grydehøj Adam , Hayward Philip
Published: February 2022

This article addresses the nature of autonomist impulses and initiatives that developed on the Isle of Wight, off the southern coast of England, in the late 20th Century. Drawing on recent discussions of the process of decolonization of island territories and the broader field of study of ethnopolitical mobilization in support of regional autonomy, the article considers the reasons why local autonomist initiatives failed to secure significant traction with the local population. Focus is placed on the historical process of identity building, on how the Isle of Wight community conceptualizes its relationship with England as a whole and of the manner in which the island and its heritage has been considered as quintessentially English.

Chat-bot as an (AI) technology has taken great attention in recent years and especially in the education sector. before applying such new technology. it is vital to Understand the determinates that affect the behaviour intention for a student to accept or reject this technology in higher education, to understand this behaviour intension, the current research applied the unified theory of acceptance and use of technology (UTAUT) with excluding for two moderators from the original model which are experience and Voluntariness of use. Additionally, this research excluded facilitating conditions and behaviour use as it aimed to investigate only the intension behaviour of the students. This study also aimed to examine the role of demographic factors (gender and age) effect on the model research independent variables and the behaviour intension variable. Therefore, the researcher put the objectives of the study that are represented in, developing a framework for the acceptance of chat-bot technology on the behaviour intension of students in higher education in Egypt. To achieve these objectives, the researcher collects data about the required variables by making a questionnaire. This questionnaire targeted students at the Arab academy for science and technology and maritime transport (AASTMT). AASTMT was selected because it represents one of the oldest private universities in Egypt that apply artificial intelligence technology in its educational system. The final sample consisted of 385 responses. data were analyzed through data testing, descriptive analysis, correlations, regression, and structural equation modelling (SEM). Results indicated a significant impact of performance expectancy, effort expectancy and social influence on students' behaviour intention to accept the chat-bot technology in their higher education in Egypt. Moreover, the results have shown that there is no moderating role of demographic factors (gender and age) proved in the relation between performance expectancy, effort expectancy, social influence, and behaviour intention

Objective. The establishment and substantiation of biostatistical trends in the state of mortality of the population of Ukraine due to diseases of the circulatory system (I00-I99) in the context of the place of residence of the deceased for the period 2009-2019.Material and methods. An epidemiological, one-time, continuous, prospective scientific study was carried out using statistical data of the State Statistics Service of Ukraine and the Center for Medical Statistics of the Ministry of Health of Ukraine for the period 2009-2019, where the author performed the compilation and processing in spreadsheets of Microsoft Office Еxcel (2019). Retrospective, biostatistical, mathematical, abstract and graphic research methods are used, as well as methods of copying, deductive awareness, structural and logical analysis taking into account the principles of systematicity.Results and discussion. The obtained results indicate that mortality due to DCS (I00-I99), during the studied period (2009-2019), is dominant in the overall mortality structure of the population of Ukraine, where ischemic heart disease (I20, I24-I25) ranks first in terms of mortality, especially among the inhabitants of rural areas of the country, while the following rankings: second, third, fourth, consistently and intransigently share cerebrovascular disease (I60-I69), myocardial infarction (I21-I24) and hypertension (I10-I15), which are dominant in the inhabitants of urban areas.Conclusions. Given the excessive and direct burden of DCS mortality on the quantitative expression of the country's population and its negative impact on people's quality of life, as well as the state of public health, socio-economic well-being and resource provision of society, the state of Ukraine is required to make decisive and effective priority adequate management decisions of preventive content, to minimize cardiovascular pathology (I00-I99) in the context of "European guidelines for the prevention of cardiovascular disease in clinical practice" (2016).
Application of DataMining clustering and classification methods in the study of the mechanisms of mutual burdening of reactive arthritis and chronic pyelonephritis in terms of connective tissue metabolism

Published: February 2022

Disorders of metabolic processes in the "proteoglycans-collagen" system, changes in enzymatic reactions in patients with reactive arthritis (ReA) are often preceded by many complications, including impaired renal function. Classical regression methods are not very informative in determining the mutual burden of ReA and chronic pyelonephritis (CP), as well as the primacy of the disease.Objective - to investigate the possible relationship between ReA and CP in order to establish early criteria for predicting the development of CP on the background of ReA on the indicators of connective tissue metabolism. Material and methods. 113 patients were examined, which were divided into two groups: the first group - patients with urogenic ReA, activity I-III. FTS I-III st. (n = 65); the second group - patients with urogenic ReA and CKD I-II: pyelonephritis in the acute phase (n = 48). The control group consisted of 20 healthy individuals. The average duration of the disease of the examined patients was 24.4 ± 4.7 months. The mean age of patients was 32.5 ± 1.2 years. DataMining clustering and classification methods were used to process the obtained research results.Results. As a result of clustering methods (k-means and fuzzy clustering), the same results of cluster membership were obtained. In particular, ReA disease was correctly diagnosed in 48 cases, which is 74% of all diagnosed, 17 people (26%) were assigned to cluster "2". There is also a mismatch in the second cluster. In particular, out of 32 people diagnosed with ReA + CP, according to mathematical calculations, 28 people (88%) got into this cluster. Four patients (13%) were assigned to cluster "1" – to the group of persons in whom only one ReA disease should be diagnosed. This indicates that the boundary between the ReA and ReA + CP clusters are somewhat blurred. And this is the basis for establishing the fact that ReA disease can gradually lead to CP.Conclusions. Using DataMining clustering methods the greatest significance was defined in the diagnostic algorithm of ReA progression of such indicators as free oxyproline (FOP), protein-bound oxyproline (PBOP), the degree of collagenolytic activity (CLA) (intensity of azocol lysis), which showed a direct dependence on the degree of activity of the inflammatory process. Increases in FOP> 13.8 μmol/l, PBOP> 65.0 μmol/l and CLA (azocol)> 0.85 μg / ml in 1 h are probable risk factors for progression and early criteria for severe ReA and CP.

Authors: ÖZDEMİR Ercan
Published: February 2022

Purpose: In the present study, the ability of middle school prospective mathematics teachers to subtract integers with counters and a number line was investigated.

Design/Methodology/Approach: A case study method was used for the investigation. The research was conducted with 37 prospective teachers who were training in a state university’s undergraduate program on primary mathematics in northern Turkey. Four questions developed by the researcher for subtraction in integers were used as a data collection tool. The data of the study were analyzed in two stages. In the first stage, the answers of the prospective teachers were determined as right or wrong; subsequently, in the second stage, the mistakes that led to the wrong answers were determined.

Findings: The prospective teachers were relatively successful with respect to both modeling types. The prospective teachers had the highest rates of success in modeling with counters, with a rate of approximately 97% in subtracting a negative integer from a positive integer ((+3) − (−5)), and the lowest rates of success in subtracting a negative integer from a negative integer, with a rate of around 89% for the operation ((−4) − (−7)). In modeling with the number line, the highest success rate was approximately 91% for subtracting a positive integer ((+2) − (+5)) from another positive integer, whereas the lowest success rate was around 86% for subtracting a negative integer from a negative integer in the operation of ((−4) − (−7))

Highlights: According to the results of the research, the prospective teachers were relatively successful in modeling the subtraction of integers using counters and a number line.

Due to their semi-nomadicnature of living, convenience sampling was used to select the participants, who wereapproached at their homes. A questionnaire was used to assess the knowledge and practicesrelating to bush meat and hygiene. Results The majority of the participants ate bush meatregularly but had poor knowledge about disease transmission. There was a significantassociation between sex and occupation with knowledge. A significant association was foundbetween knowledge on disease transmission with the consumption of bush meat. There wasno association between practice on cooking, hunting activities and handling carcasses andhand hygiene practice with the consumption of bush meat. Conclusion Most Jahai lackedsufficient knowledge on disease transmission and have poor practices regarding the handlingof bush meat and its carcasses, which might put them at a risk of infection. The findings canbe used as baseline data to develop effective strategies such as cultural-sensitive educationalprograms, to deepen the understanding of the community on the risk and prevention ofdeveloping diseases.

Latar Belakang dan Tujuan: Stroke menurut WHO adalah terjadinya gejala penurunan fungsi neurologis secara tiba-tiba, fokal maupun global, berlangsung lebih dari 24 jam karena gangguan pasokan darah menuju ke otak. Stroke merupakan penyakit multifaktorial penyebab kematian dan disabilitas. Sebagian besar pasien stroke memiliki ≥ 2 faktor risiko. Tujuan penelitian ini adalah untuk membandingkan gambaran luaran klinis pada pasien stroke iskemik fase akut dengan satu atau lebih faktor risiko. Subjek dan Metode: Penelitian ini merupakan penelitian deskriptif retrospektif pada pasien stroke iskemik fase akut serangan pertama di Departemen Neurologi Rumah Sakit Hasan Sadikin Bandung periode 2015–2019. Hasil: Terdapat 176 subjek pada penelitian ini, 160 pasien (90,9%) dengan lebih dari satu faktor risiko dan 16 pasien (9,1%) dengan satu jenis faktor risiko. Faktor risiko paling banyak adalah hipertensi sebanyak 147 pasien (83,5%), dislipidemia 91 pasien (51,7%) dan penyakit kardiovaskular 56 orang (31,8%). Penelitian menunjukan luaran klinis yang diukur dengan skor National Institute of Health Stroke Scale (NIHSS) keluar RS pada kelompok lebih dari satu faktor risiko lebih bervariatif dari derajat ringan hingga sangat berat. Sedangkan, pada kelompok dengan satu faktor risiko skor NIHSS cenderung ringan hingga sedang. Simpulan: Pasien dengan lebih dari satu faktor risiko memiliki luaran klinis lebih buruk dibandingan pasien dengan satu faktor risiko.

Latar Belakang dan Tujuan: Disabilitas yang berat pada stroke meningkatkan risiko terjadinya malnutrisi. Malnutrisi pada pasien stroke dapat disebabkan oleh defisit neurologis dan faktor risiko. Malnutrisi pada stroke meningkatkan morbiditas dan mortalitas. Penelitian ini bertujuan untuk mengetahui karakteristik klinis dan status nutrisi pasien stroke. Subjek dan Metode: Penelitian bersifat deskriptif retrospektif pada pasien stroke yang dirawat di RSUP Hasan Sadikin Bandung pada periode 1 Agustus 2020 hingga 30 September 2020. Status nutrisi dinilai menggunakan Indeks Massa Tubuh (IMT) dan skor Subjective Global Assessment (SGA). IMT dihitung menggunakan kg/m2, dikelompokkan menjadi obesitas (IMT >30), overweight (IMT 25,0–29,9), normal (IMT 18,5–24,9) dan underweight (IMT <18,5). Skor SGA <2 termasuk nutrisi baik, dan ≥2 tergolong malnutrisi. Hasil: Didapatkan 52 orang pasien stroke yang sebagian besar berjenis kelamin laki-laki (57,7%) dengan rentang usia 38–86 tahun (rata-rata 57 tahun), 51,9% mengalami malnutrisi berdasarkan skor SGA, IMT normal dan overweight sebanyak 23 (44,2%) orang, diikuti obesitas (5,7%) dan underweight (5,7%). Ditemukan 71,4% usia ≥65 tahun mengalami malnutrisi. Kondisi malnutrisi didominasi pasien stroke infark kardioemboli (63,6%), dengan derajat stroke berat (58,3%), disfagia (59,4%), dengan komorbid infeksi (71,4%) dan stress ulcer (55,6%). Simpulan: Berdasarkan penelitian ini, didapatkan bahwa usia tua , derajat stroke sedang-berat, komorbid infeksi dan stress ulcer akan memiliki kecenderungan malnutrisi sehingga penanganan stroke yang baik dapat menurunkan risiko terjadinya malnutrisi. Kejadian stroke berulang tidak menjadi risiko terjadinya malnutrisi pada penelitian ini.

Hemofilia adalah kelainan darah bawaan yang serius dengan wanita sebagai pembawa, terutama didapatkan pada pria dan berlangsung sepanjang hidup dimana hemofilia A merupakan tipe hemofilia tersering. Ketika salah satu faktor yang diperlukan untuk pembekuan darah hilang atau memiliki fungsi yang tidak memadai, mekanisme koagulasi yang terganggu menyebabkan perdarahan yang tidak dapat dihentikan. Saat ini, penyebab kematian paling umum di antara pasien hemofilia adalah perdarahan otak karena trauma kepala. Kasus perdarahan intrakranial sebisa mungkin dilakukan tindakan operasi segera untuk mendapatkan prognosis yang lebih baik. Tindakan evakuasi perdarahan harus dikerjakan dalam waktu singkat namun memiliki resiko tinggi terjadinya perdarahan ulang. Pemberian penggantian faktor VIII rekombinan untuk pengobatan perdarahan akut pada pasien hemofilia A berat harus dilakukan segera. Rumatan anestesi juga harus mencakup penurunan resiko hipertensi dan takikardia untuk meminimalkan terjadinya perdarahan. Laki-laki usia 17 tahun dengan diagnosa penurunan kesadaran cedera kepala 2x4 karena perdarahan intracranial subdural hemorrhage (SDH) regio frontotemporoparietal sinistra dan edema cerebri hari ke 4 disertai herniasi subfalcine ke kanan dengan hemofilia A direncanakan tindakan trepanasi dekompresi evakuasi SDH. Pasien mendapatkan injeksi faktor VIII 4000 unit sebelum operasi. Durante operasi perdarahan 1100cc dan mendapat transfusi 1940cc produk darah hingga hemodinamik stabil. Post operatif pasien dilakukan perawatan di ICU selama 8 hari, dilakukan extubasi setelah kondisi membaik.

Tumor hipofisis dapat disertai gejala neuropsikiatri. Apopleksia pituitari (AP) merupakan kejadian jarang akibat infark dan perdarahan tumor hipofisis. Pemulihan total masih mungkin terjadi walaupun pada kasus berat dengan terapi pembedahan maupun konservatif. Terapi pembedahan dipilih bila adanya tanda peningkatan intrakranial dengan kondisi klinis dan neurologis yang tidak stabil. Seorang laki laki, umur 36 tahun dengan keluhan gangguan bicara mendadak sehari sebelum masuk RS, dengan riwayat terapi skizofrenia selama 8 bulan. Pasien mengalami penurunan kesadaran dalam perawatan dan didiagnosis tumor hipofisis anterior dengan komponen apopleksia dari CT-scan kepala. Pasca operasi transphenoid urgensi diterapi vasopresin intramuskular akibat poliuria. Penatalaksanaan anestesi pada pembedahan AP tidak berbeda dengan tumor hipofisis lainnya, hanya saja kondisi AP dapat bersifat urgensi. Satu bulan pasca pembedahan, pasien sudah lebih mudah berbicara, mulai beraktifitas fisik, dan halusinasi suara sudah tidak ada. Tatalaksana AP memberikan tantangan dalam manajemennya. Keluhan yang ditemukan dapat berupa halusinasi. Hingga kasus ini dilaporkan, ada satu publikasi kasus AP dengan psikosis akut dan keterlambatan diagnosis masih mungkin terjadi. Kecurigaan gangguan organik tetap perlu dipikirkan pada gangguan neuropsikiatri. Gangguan produksi urin bisa terjadi pasca operasi yang disebabkan beberapa hal sehingga memerlukan pemantauan ketat status hidrasi untuk menghindari morbiditas dan mortalitas yang mungkin terjadi.

Vasospasme cerebral merupakan penyebab morbiditas dan mortalitas utama pada pasien dengan perdarahan subarahonid. Delayed ischemic neurologic deficit yang berhubungan dengan vasospasme serebral menyebabkan kematian pada 50% pasien yang bertahan pada periode awal setelah aneurisma ruptur yang ditangani. Onset vasospasme serebral yang bervariasi, mulai dari 24 jam pasca perdarahan subarahnoid atau subarahcnoid hemorrhage (SAH) sampai dengan 14 hari, patofisiologi vasospasme serebral yang kompleks dan cara diagnosis yang masih kontroversial, turut berkontribusi terhadap morbiditas dan mortalitas yang tinggi pada pasien dengan SAH. Evaluasi ketat selama perawatan di ICU untuk mendeteksi kejadian vasospasme serebral awal sangat penting, setiap gejala neurologis baru yang muncul harus diperiksa dan ditangani secepatnya. Banyak obat-obatan yang diteliti untuk mengatasi vasospasme serebral namun efektifitasnya masih dipertanyakan. Tatalaksana utama yang dulu diketahui adalah dengan melakukan terapi triple H, namun hal ini sudah ditinggalkan. Induced hypertension menjadi satu-satunya bagian dari terapi triple H yang masih digunakan, namun belum banyak dipergunakan secara luas. Oleh karena itu perlu dikaji lebih lanjut bagaimana tatalaksana SAH untuk mencegah luaran yang buruk.

Konsep dasar Neuroanestesi & Neuro Critical Care disebut sebagai ABCDE neuroanestesi. Early Brain Injury (EBI) dahulu dikenal sebagai cedera otak primer. Pada EBI terjadi hilangnya autoregulasi, hilangnya integritas barier darah otak. Adanya Trias Cushing menunjukkan adanya hipertensi intrakranial. Target tekanan darah pada cedera otak traumatik (traumatic brain injury/TBI) adalah hindari tekanan darah sistolik <110 mmHg, pertahankan tekanan perfusi otak (cerebral perfusion pressure/CPP) 60-70 mmHg, target pengaturan PaCO2 adalah normokarbia, PaCO2 35–40 mmHg, penggunaan profilaksis phenytoin atau valproate tidak direkomendasikan untuk mencegah late post traumatic seizure (late PTS). Masih perlu menganalisa terapi decompressive craniectomy (DECRA) dibandingkan dengan terapi medikal kontinyu untuk peningkatan tekanan intrakranial (intracranial pressure/ICP) yang refrakter setelah TBI. Anestesi umum untuk pasien dengan TBI berat lebih baik dengan total intravenous anesthesia (TIVA), pemberian cairan harus mempertimbangkan osmolaritas cairan tersebut. Pada konsep yang baru, pada pasien dengan peningkatan ICP, konsentrasi anestetika volatil harus dibatasi sampai 0,5 MAC. Target gula darah adalah normoglikemia. Hipotermi profilaksis atau terapeutik tampaknya tidak memiliki tempat dalam pengelolaan cedera otak berat
