Authors: Leines Medina D. , Berlanga Reséndiz K. , Rocha Campos X. , Hernández Pérez A.C.
Published: January 2023

Hoy en día son frecuentes los problemas generados por un ritmo de vida acelerado; es común encontrar problemas de salud, como la obesidad, diabetes, insomnio, ansiedad, problemas estomacales y digestivos entre otros. Estudios confirman que gran parte de la población busca en el consumo de infusiones tipo “Te”, solucionar alguna de estas problemáticas. En este sentido, la okra (Abelmoschus esculentus) es una planta tropical de fruto comestible, originaria de África y perteneciente a la familia de las malváceas, conocida como quingombó, gombo, molondrón u okra; en México se le conoce como quimbombó o simplemente okra. La okra crece en regiones tropicales de clima cálido, en algunas regiones es considerada un alimento, aprovechando su tallo, hojas y fruto; es consumida por su valor nutrimental, poseedora de antioxidantes naturales que ayudan a prevenir padecimientos como estrés oxidativo, daño celular, cúmulo de placas lipídicas en vasos sanguíneos, colesterol entre otros. Particularmente es una planta silvestre de la Huasteca Potosina, utilizada de forma empírica y limitada por pobladores de la Zona Tének de Ciudad Valles, S.L.P., sin aprovechar su semilla, ni dar valor agregado a ella por su gran aporte nutrimental. Por lo anterior, se propone OKRAF´T, una infusión tipo café a base de semilla de okra, sin cafeína, con antioxidantes y alto valor nutrimental. Un producto atractivo, sostenible, saludable e innovador que aporte a través de su consumo una mejora en la calidad de vida del consumidor.

Published: January 2023

El acero en la vida cotidiana es de gran importancia, en los últimos años la tendencia con respecto al procesamiento del material en sus múltiples aplicaciones, han generado medidas más respetuosas con el medio ambiente. El acero ofrece un gran potencial en aplicaciones por sus propiedades mecánicas, su alta relación resistencia/peso y propiedades de elongación. Este estudio tuvo como fin comprender la inferencia del hidróxido de calcio como medio de enfriamiento en el proceso de temple, comparándolo con aquellos tradicionales, e interpretarlo mediante los métodos de Tukey y Duncan, fueron necesarias 72 probetas que pasaron por los procesos de corte, lijado y pulido calidad espejo, a 36 se les aplicó un tratamiento térmico y se llevaron a una temperatura de austenización por un promedio de 1.30 horas, después de esto se sometieron a un enfriamiento rápido en distintas concentraciones de calcio Ca(OH)₂, lo que determinó los cambios estructurales midiendo las durezas. Se obtuvieron las durezas de los cambios estructurales y con los gráficos estadísticos se observa su resistencia a la penetración en kgf/cm2 y mediante los métodos de comparación múltiple Tukey y Duncan, se infiere el comportamiento de la cal en la dureza de las muestras, para plantear la posibilidad de utilizar el desecho industrial del proceso de nixtamalización de la industria de la masa y la tortilla “nejayote” como alternativa para medio de enfriamiento.

Process-oriented models of autumn leaf phenology: ways to sound calibration and implications of uncertain projections
Authors: Meier Michael , Bigler Christof
Published: January 2023

Abstract. Autumn leaf phenology marks the end of the growing season, during which trees assimilate atmospheric CO2. Since autumn leaf phenology responds to climatic conditions, climate change affects the length of the growing season. Thus, autumn leaf phenology is often modelled to assess possible climate change effects on future CO2 mitigating capacities and species compositions of forests. Projected trends have been mainly discussed with regards to model performance and climate change scenarios. However, there has been no systematic and thorough evaluation of how performance and projections are affected by the calibration approach. Here, we analyzed >2.3 million performances and 39 million projections across 21 models, 5 optimization algorithms, ≥7 sampling procedures, and 26 climate model chains from two representative concentration pathways. Calibration and validation were based on >45 000 observations for beech, oak, and larch from 500 Central European sites each. Phenology models had the largest influence on model performance. The best performing models were (1) driven by daily temperature, day length, and partly by seasonal temperature or spring leaf phenology and (2) calibrated with the Generalized Simulated Annealing algorithm (3) based on systematically balanced or stratified samples. Assuming an advancing spring phenology, projected autumn phenology shifts between 13 and +20 days by 2080–2099, resulting in a lengthening of the growing season by 7–40 days. Climate scenarios and sites explained more than 80 % of the variance in these shifts and thus had eight to 22 times the influence of phenology models. Warmer climate scenarios and better performing models predominantly extended the growing season more than cooler scenarios and poorer models. Our results justify inferences from comparisons of process-oriented phenology models to phenology-driving processes and we advocate species-specific models for such analyses and subsequent projections. For sound calibration, we recommend a combination of cross-validations and independent tests, using randomly selected sites from stratified bins based on mean annual temperature and average autumn phenology, respectively. Poor performance and little influence of phenology models on autumn phenology projections suggest that the models are overlooking relevant drivers. While the uncertain projections indicate an extension of the growing season, further studies are needed to develop models that adequately consider the relevant processes for autumn phenology.

Published: January 2023

Abstract. A second occurrence of bobtraillite is described from the
Gejiu nepheline syenite, southwestern China. The extremely rare and complex
boron-bearing zirconium silicate is associated with albite, orthoclase,
jadeite, fluorite, andradite, titanite, as well as other REE and
zirconium-bearing minerals, catapleiite, moxuanxueite, låvenite,
eudialyte, britholite-(Ce), and calcioancylite-(La). The EMP and LA-ICP-MS
analyses of the studied material give an empirical formula:
(Na9.70Li0.42K0.08□1.80)Σ12.00(Sr10.61Ca1.14Fe0.07□0.18)Σ12.00(Zr12.87Ti0.53Nb0.31REE0.08Y0.06U0.02Th0.01□0.12)Σ14.00(Si42.41B5.59Al0.02)Σ48.02O132(OH)12 ⚫ 12H2O. Bobtraillite is trigonal,
with space group P3¯c1, a=19.6977(6), c=9.9770(3) Å, V=3352.4(2) Å3, Z=1. Single-crystal structure refinement revealed
that all sodium occupies the Na(1) and Na(2) sites; the site occupancy of
these two positions is 0.835(18) and 0.15(2), respectively, suggesting that
Na(1) site is Na dominant, while Na(2) is a vacancy-dominant site. The
[8]-coordinated site has been assigned to Sr and Ca, with free
occupancy factors, 0.874(10) and 0.126(10), respectively. These new data
indicate that the ideal formula of bobtraillite could be written as
(Na,□)12(□,Na)12Sr12Zr14(Si3O9)10[Si2BO7(OH)2]6 ⚫ 12H2O.
SHAFTS (v2022.3): a deep-learning-based Python package for simultaneous extraction of building height and footprint from sentinel imagery
Authors: Li Ruidong , Sun Ting , Tian Fuqiang , Ni Guang-Heng
Published: January 2023

Abstract. Building height and footprint are two fundamental urban morphological features required by urban climate modelling.
Although some statistical methods have been proposed to estimate average building height and footprint from publicly available satellite imagery, they often involve tedious feature engineering which makes it hard to achieve efficient knowledge discovery in a changing urban environment with ever-increasing earth observations.
In this work, we develop a deep-learning-based (DL) Python package – SHAFTS (Simultaneous building Height And FootprinT extraction from Sentinel imagery) to extract such information.
Multi-task deep-learning (MTDL) models are proposed to automatically learn feature representation shared by building height and footprint prediction.
Besides, we integrate digital elevation model (DEM) information into developed models to inform models of terrain-induced effects on the backscattering displayed by Sentinel-1 imagery.
We set conventional machine-learning-based (ML) models and single-task deep-learning (STDL) models as benchmarks and select 46 cities worldwide to evaluate developed models’ patch-level prediction skills and city-level spatial transferability at four resolutions (100, 250, 500 and 1000 m). Patch-level results of 43 cities show that DL models successfully produce discriminative feature representation and improve the coefficient of determination (R2) of building height and footprint prediction more than ML models by 0.27–0.63 and 0.11–0.49, respectively.
Moreover, stratified error assessment reveals that DL models effectively mitigate the severe systematic underestimation of ML models in the high-value domain: for the 100 m case, DL models reduce the root mean square error (RMSE) of building height higher than 40 m and building footprint larger than 0.25 by 31 m and 0.1, respectively, which demonstrates the superiority of DL models on refined 3D building information extraction in highly urbanized areas.
For the evaluation of spatial transferability, when compared with an existing state-of-the-art product, DL models can achieve similar improvement on the overall performance and high-value prediction.
Furthermore, within the DL family, comparison in building height prediction between STDL and MTDL models reveals that MTDL models achieve higher accuracy in all cases and smaller bias uncertainty for the prediction in the high-value domain at the refined scale, which proves the effectiveness of multi-task learning (MTL) on building height estimation.

Abstract. State-of-the-art Earth system models typically employ grid spacings of O(100 km), which is too coarse to explicitly resolve main drivers of the flow of energy and matter across the Earth system. In this paper, we present the new ICON-Sapphire model configuration, which targets a representation of the components of the Earth system and their interactions with a grid spacing of 10 km and finer. Through the use of selected simulation examples, we demonstrate that ICON-Sapphire can (i) be run coupled globally on seasonal timescales with a grid spacing of 5 km, on monthly timescales with a grid spacing of 2.5 km, and on daily timescales with a grid spacing of 1.25 km; (ii) resolve large eddies in the atmosphere using hectometer grid spacings on limited-area domains in atmosphere-only simulations; (iii) resolve submesoscale ocean eddies by using a global uniform grid of 1.25 km or a telescoping grid with the finest grid spacing at 530 m, the latter coupled to a uniform atmosphere; and (iv) simulate biogeochemistry in an ocean-only simulation integrated for 4 years at 10 km. Comparison of basic features of the climate system to observations reveals no obvious pitfalls, even though some observed aspects remain difficult to capture. The throughput of the coupled 5 km global simulation is 126 simulated days per day employing 21 % of the latest machine of the German Climate Computing Center. Extrapolating from these results, multi-decadal global simulations including interactive carbon are now possible, and short global simulations resolving large eddies in the atmosphere and submesoscale eddies in the ocean are within reach.

Abstract. The seasonal cycle of the Antarctic sea ice extent is strongly asymmetric,
with a relatively slow increase after the summer minimum followed by a more
rapid decrease after the winter maximum. This cycle is intimately linked to
the seasonal cycle of the insolation received at the top of the atmosphere,
but sea ice processes as well as the exchanges with the atmosphere and ocean
may also play a role. To quantify these contributions, a series of idealized
sensitivity experiments have been performed with an eddy-permitting
(1/4∘) NEMO-LIM3 (Nucleus for European Modelling of the Ocean–Louvain-la-Neuve sea ice model version 3) Southern Ocean configuration, including a
representation of ice shelf cavities, in which the model was either driven
by an atmospheric reanalysis or coupled to the COSMO-CLM2 regional
atmospheric model. In those experiments, sea ice thermodynamics and dynamics
as well as the exchanges with the ocean and atmosphere are strongly
perturbed. This perturbation is achieved by modifying snow and ice thermal
conductivities, the vertical mixing in the ocean top layers, the effect of
freshwater uptake and release upon sea ice growth and melt, ice dynamics, and surface
albedo. We find that the evolution of sea ice extent during the ice advance
season is largely independent of the direct effect of the perturbation and
appears thus mainly controlled by initial state in summer and subsequent
insolation changes. In contrast, the melting rate varies strongly between
the experiments during the retreat, in particular if the surface albedo or
sea ice transport are modified, demonstrating a strong contribution of those
elements to the evolution of ice coverage through spring and summer. As with
the advance phase, the retreat is also influenced by conditions at the
beginning of the melt season in September. Atmospheric feedbacks enhance the
model winter ice extent response to any of the perturbed processes, and the
enhancement is strongest when the albedo is modified. The response of sea
ice volume and extent to changes in entrainment of subsurface warm waters to
the ocean surface is also greatly amplified by the coupling with the
atmosphere.

Published: January 2023

Uzaktan eğitim ile eğitim veren kurum sayısının her geçen gün arttığı bilinmektedir. Pandemi ile birlikte örgün eğitim kurumlarında uzaktan eğitim ile verilen ders sayılarında da artış olmuştur. Bu artış ile birlikte niteliksel durumun analizi de önemli bir hal almaktadır. Bu çalışmada örgün eğitim öğrencisi olan ve bazı derslerini uzaktan eğitim platformunda alan öğrencilerin uzaktan eğitim derslerinin kalitesi ile ilgili görüşlerinin incelenmesi amaçlanmıştır.

Çalışmada “Uzaktan Eğitim Hizmet Kalitesi (UE-SERVQUAL)” ölçeği ile veri toplanarak nicel bir araştırma gerçekleştirilmiştir. Ölçek e-öğrenme, güvenirlik, erişilirlik ve heveslilik olmak üzere toplam dört alt faktörden oluşmaktadır. Çalışma Anadolu’da bulunan bir devlet üniversitesinde gerçekleştirilmişidir. Üniversite Ortak Seçmeli dersi olan Bilişim Teknolojileri ve Uygulamaları dersini alan önlisans öğrencileri çalışmaya katılmıştır. Çalışmada, Sağlık Kurumları İşletmeciliği, Bilgisayar Programcılığı, Fotoğrafçılık ve Halkla İlişkiler Bölümlerinde okuyan toplam 159 öğrenci bulunmaktadır. Öğrencilerin hizmet kalitesi ölçeğine verdiği cevaplar betimsel istatistikler, t-tesi ve ANOVA testi ile analiz edilmiştir. Öğrencilerin hizmet kalitesi ile ilgili görüşlerinin belirlenmesinde betimsel istatistik kullanılmıştır. Cinsiyete göre farklılığın belirlenmesinde t-testi ve bölümlere göre farklılığın belirlenmesinde ANOVA testi kullanılmıştır.

Çalışma sonunda öğrencilerin hizmet kalitesi ile ilgili görüşlerinin olumlu olduğu, her bir alt faktörde değerlerin ortalamanın üstünde çıktığı belirlenmiştir. Öğrencilerin cinsiyetlerinin ve okudukları bölümün hizmet kalitesi ile ilgili görüşlerinde anlamlı bir farklılık oluşturmadığı tespit edilmiştir.

Yapılan çalışmada araştırma yapılan dersin uzun yıllardır online olarak verilmeye devam ettiği buna rağmen öğrencilerin dersin uzaktan olmasına pek fazla adapte olamadığı ve genellikte katılım sorunu yaşandığı bilinmektedir. Ancak öğrencilerin pandemi ile birlikte dersin online olarak verilmesini kabul ederek sürece daha çok dahil olduğu görülmüştür. Literatürden farklı olarak hizmet kalitesindeki olumlu görüşün ana nedenini bu durumun oluşturmuş olabileceği düşünülmektedir. Bu nedenle çalışma sonucunda dile getirilen öneriler arasında hizmet kalitesi ile ilgili çalışmaların farklı dersler kapsamında tekrar edilebileceği bulunmaktadır.

Minat belajar mengacu pada kecenderungan siswa untuk memperoleh pengetahuan dan keterampilan dalam mata pelajaran tertentu. Salah satu penentu keberhasilan proses pembelajaran adalah minat belajar. Siswa yang memiliki minat belajar yang tinggi akan mencapai hasil belajar yang baik. Ada dua faktor utama dalam menentukan minat belajar; faktor internal dan eksternal. Investigasi awal di SMP 3 Sungguminasa mengungkapkan bahwa hasil belajar matematika siswa mengalami penurunan dari tahun 2019 ke tahun 2021, oleh karena itu perlu dilakukan penelitian lebih lanjut mengenai permasalahan tersebut. Pendekatan data mining dapat dimanfaatkan untuk mengekstrak informasi penting dan relevan dari data siswa untuk mengetahui faktor-faktor apa saja yang mempengaruhi penurunan dalam pembelajaran matematika. Populasi data dalam penelitian ini adalah 1093 siswa SMPN 3 Sungguminasa. Penulis mengambil 15% dari total populasi sebagai sampel yang representatif. Variabel penelitian terdiri dari faktor internal (perhatian, rasa ingin tahu, hobi, kecerdasan, gaya belajar, kesehatan psikologis), dan faktor eksternal (aspek sekolah, aspek keluarga, dan aspek masyarakat). Berdasarkan pendekatan yang diusulkan, penulis mengidentifikasi bahwa faktor utama penyebab penurunan minat belajar siswa adalah faktor eksternal, yaitu fasilitas sekolah. Fasilitas sekolah seperti media/alat pengajaran yang tepat akan menentukan keberhasilan proses belajar mengajar matematika. Faktor-faktor seperti hobi, disiplin guru, suasana rumah, dan kondisi ekonomi merupakan faktor lain yang mempengaruhi minat belajar matematika siswa SMPN 3 Sungguminasa.

Thematic real work lecture is a form of implementation of the higher education in which it provides real work experience and learning for students in the implementation of community service and empowerment. Thematic real work lecture  activities are a golden opportunity for students to be more critical, innovative, active, and creative in finding the right solutions, formulations and strategies in solving problems and developing in the village. Development is often interpreted as meeting the needs of physical facilities and infrastructure imported from outside, carried out with a very dominant government role and with top-down planning. Likewise with village and rural development, which at the location Bagoang village, initially there was a village boundary monument, but due to building maintenance that was never paid attention to and factors from the age of the building itself which was quite old, causing the monument to collapse and reach currently no new village boundary monument has been made, so based on the consideration of our group, we intend to do community service by making building plans and constructing boundary monuments in Bagoang Village.

The Regency Apparatus Work Unit (SKPK) is an apparatus of the Regional Government (Provincial and Regency/City) in Indonesia. SKPK is the executor of executive functions that need to be coordinated for the success of government administration. The legal basis for the formation of the SKPK is in article 120 of Law No. 32 of 2004 concerning Regional Government. The Department of Communication,  Informatics, and Encryption Service (Diskominfosa) is an agency that is fully responsible for processing information within the Government in Indonesia. The purpose of this application is to collect the data in various offices in Bireuen Regency and store it in the database. The system is web-based that uses the PHP framework Codeigniter 3 and also using the Bootstrap framework. Initially, this study applied field research using the interview as the primary data and the Reports of the Evaluation on Accountability Performance at The Regency Apparatus Work Unit of Bireuen District as the secondary data. In developing the application, the waterfall is applied as a software model used. As the result, the application shifted the manual data processing into the system such as filtering the report based on a daily, monthly, and even yearly basis. In addition, they can check the status of their application data by entering the SKPK code that has been made. This SKPK application data collection information system was created with the aim of making data management orderly and checking the status of the Regency Apparatus Work Unit (SKPK) application easier and more precise.

A pandemia de Covid-19 ressaltou a importância do jornalismo local porque tem sido através dele que as pessoas estão se informando sobre os riscos, os cuidados e a evolução da doença na sua vizinhança, que lhe diz respeito e afeta suas vidas mais diretamente. Este artigo apresenta os resultados de uma pesquisa exploratória que teve como objetivo coletar impressões e experiências entre profissionais da imprensa local sobre seu trabalho nesta crise sanitária. A pesquisa foi realizada no segundo semestre de 2021 através de um e-survey aplicado entre membros de equipes de reportagens de diferentes mídias de Campos dos Goytacazes, um centro urbano com 514.643 habitantes, localizado a 300 Km da capital fluminense, Rio de Janeiro. O estudo permitiu identificar questões relacionadas às condições de trabalho dos respondentes, às relações de poder e conflito envolvendo comercial, administrativo e redações, aos critérios de noticiabilidade e ao papel social do jornalismo local para seu público.

The aim of this research was to investigate individual and club-level variables that explain individual differences in gymnasts´ motor performance (MP). The sample was comprised of 249 female gymnasts (68 elite; 181 non-elite), aged between 9 and 20 years, split into four age categories: 9-10 years (n=98); 11-12 years (n=72); 13-15 years (n=64), and 16 and above (n=15). Gymnasts were from 26 Brazilian clubs, from six different states. The Talent Opportunity Program physical ability total test score was used to assess gymnasts’ MP, based on a battery of seven tests: handstand hold, cast, rope climb, press handstand, leg flexibility, leg lift, and 20 meter sprint. Anthropometric, body composition, biological maturation, and training history data were also collected, as were club dimensions, infrastructures, competitions, manpower, and availability of selection/talent programs. Data were analyzed using a multilevel modelling approach. Individual gymnast’ characteristics explained 39% of physical ability score variance from which 32% was related to the independent effects of age, competitive level, fat free mass, occurrence of menarche, and trainings hours per week (p<0.05). Club characteristics explained 61% of gymnasts’ total variance in physical ability score; 96% of this amount was related to club dimension, manpower, and talent program. These results reinforce the relevant role of the contextual effects and highlight the need to invest in club infrastructures: ideally in coaches’ expertise and effective selection programs. Such investments should enable the enhancement and development of a gymnast’s careers during their lifetime involvement in training and competition.

Colonoscopic polypectomy is effective in decreasing the incidence and mortality of colorectal cancer (CRC). Premalignant polyps discovered during colonoscopy are associated with the risk of metachronous advanced neoplasia. Postpolypectomy surveillance is the most important method for managing advanced metachronous neoplasia. A more efficient and evidence-based guideline for postpolypectomy surveillance is required because of the limited medical resources and concerns regarding colonoscopy complications. In these consensus guidelines, an analytic approach was used to address all reliable evidence to interpret the predictors of CRC or advanced neoplasia during surveillance colonoscopy. The key recommendations state that the high-risk findings for metachronous CRC following polypectomy are as follows: adenoma ≥10 mm in size; 3 to 5 (or more) adenomas; tubulovillous or villous adenoma; adenoma containing high-grade dysplasia; traditional serrated adenoma; sessile serrated lesion containing any grade of dysplasia; serrated polyp of at least 10 mm in size; and 3 to 5 (or more) sessile serrated lesions. More studies are needed to fully comprehend the patients who are most likely to benefit from surveillance colonoscopy and the ideal surveillance interval to prevent metachronous CRC.
Self-organization and the Process of Dynamic Learner Language Development
Authors: An Shan
Published: January 2023

Adopting Complex Dynamic Systems Theory (CDST) in Second Language Acquisition (SLA) is a testament to the revolutionary and evolutionary advancement in theory and empirical practice in the field. CDST is revolutionary for the fact that it warrants systems thinking of SLA phenomena that breaks the chain of dichotomous conceptualization on vital issues such as the mechanism of language acquisition and learning and the effectiveness of positive and negative evidence. The emergence of CDST, on the other hand, is an evolutionary product nurtured by the painstaking collaborations of SLA scholars for over two decades of scientific inquiry (see, e.g., Han, 2019; Hiver & Al-Hoorie, 2019; Larsen-Freeman & Cameron, 2008; Ortega & Han, 2017). To capitalize on CDST as a valid approach to scholarly work, it is necessary to grapple with its fundamental constructs. This forum piece accentuates a critical notion of CDST: self-organization. By first referring to the theoretical aspects of self-organization, this forum piece seeks to demonstrate the relevance of this notion in SLA. This piece will then review three sample studies homing in on learner language development with a CDST lens and a specific focus on self-organization.
The “Problem” of L2 Writers in College Composition Placement: Identity, Outcomes, and the Future of Directed Self Placement
Authors: Guida Mesina Vanessa
Published: January 2023

In response to the rapidly growing number of international and multilingual students on U.S. college campuses, many colleges’ first year composition (FYC) courses have expanded to include classes designated for “ESL” or “International” students, with increasing scholarship on the best pedagogical practices for such classes.  Despite increasing scholarship on the best pedagogical practices for such classes, the implications of placing students into them remains “the thorniest of issues” (Crusan, 2011), with mounting debate as to how to measure L2 students’ suitability for either “ESL” or “mainstream” writing classes, as well as the role students should play in labelling themselves “ESL” writers. Directed Self-Placement (DSP) is emerging as a more equitable and anti-racist alternative to test-based placement; however, there are concerns about its suitability for L2 writers specifically (Crusan, 2011; Ferris, 2017). This literature review therefore aims to address two questions: (1) what are the unique challenges of placing L2 writers in FYC courses? Specifically, what are the implications of the identity labelling inherent in placing L2 students in courses designated as “ESL” or for “International Students” with regard to student investment and learning outcomes?  (2) Might DSP offer a viable alternative to traditional L2 placement testing that addresses such implications?

Published: January 2023

INTRODUCTION: Intraoperative blood loss is considered to be one of the major complications in neurosurgical operations and neurosurgical procedures and is directly related to the postoperative morbidity and mortality. Administration of Tranexamic acid [TXA] by reducing blood loss has resulted in survival benefits in Traumatic Brain Injury [TBI] population, as shown in two recent meta-analysis.
AIMS AND OBJECTIVES: To study the effect of tranexamic acid on blood loss in brain tumor resection surgery.
MATERIAL AND METHODS: Patients of either sex, aged 18-65 years who were undergoing brain tumour resection were randomly allocated to either group - the study group and the control group (30 patients in each group). Patients in the study group received tranexamic acid intravenously @10 mg/kg body weight over 10 minutes after induction and then maintenance of continuous infusion @ 1mg/kg/hr intraoperatively till skin closure. Patients in the control group received the same volume of saline per kg body weight as the volume of tranexamic acid in study group.
RESULTS: The average drop in haemoglobin and HCT was significantly lower in TXA group. Accordingly, amount of blood loss was less in TXA group compared to saline group. (332ml vs 576 ml; p = 0.011).
CONCLUSION: From our study, it was concluded that the administration of TXA resulted in a significant reduction in blood loss. TXA can thus be suggested as a cost effective method of reducing mortality due to hemorrhage in brain tumor surgery.

Keywords: Tranexamic acid [TXA], Traumatic Brain Injury [TBI].
