La reconfiguración de la esfera pública en América Latina: un acercamiento analítico desde la ciudadanía subalterna
Authors: Sandoval Forero Eduardo Andrés , Capera Figueroa José Javier
Published: April 2021

La democracia se ha constituido en uno de los temas de gran interés y debate para las ciencias sociales, en particular para el campo de la sociología política en América Latina. El trayecto histórico que ha tenido la esfera de lo público se ha convertido en un espacio epistémico encargado de reconfigurar las relaciones sociopolíticas que existen entre la ciudadanía y el Estado en el marco de los procesos endógenos/exógenos que constituyen la democracia en su concepción de lo público. Así pues, el propósito del presente artículo consiste en realizar un breve análisis sobre la discusión de la democracia en el marco del imaginario de los grupos subalternos que ejercen una mirada crítica sobre los procesos hegemónicos fomentados por los grupos dominantes, los cuales instituyen un modelo propio de la democracia moderna/liberal que está en función de un orden político en el plano vertical que genera actores marginados en la región.
Los derechos humanos y la paz en disputa: una lectura crítica en clave relacional
Authors: Acosta Navas Juan Pablo
Published: April 2021

Pese a la consolidación de teorías y perspectivas críticas en las discusiones contemporáneas en materia de derechos humanos, estas siguen en gran medida limitadas a la esfera jurídico-normativa y ligadas a la narrativa occidental hegemónica del liberalismo, negando el contenido relacional de los derechos humanos y su proceso constante de reconstrucción a partir de la interacción de los sujetos que son titulares de esos derechos. Una perspectiva crítica de los derechos humanos debe apuntar a desmontar, entre otras, la idea de que los derechos humanos se constituyen de manera exclusiva por los Estados, y que son estos los únicos llamados a su respeto y garantía.

A narrative study of students’ and staff’s experiences of living with HIV and AIDS at Rhodes University
Authors:   , Tsope Linwide
Published: April 2021

A narrative study of students’ and staff’s experiences of living with HIV and AIDS at Rhodes University Research on HIV and AIDS in university settings, especially research exploring the experience of living with the disease, has been minimal. As a response to the knowledge and research gaps, this thesis is a qualitative study involving students and staff living with HIV (LWH) and accessing treatment (ART) at the Rhodes University Health Care Centre. This study explored the personal and social symbolisms as well as meanings attached to living with HIV, through in-depth interviews with ten students and staff living with HIV, all purposively sampled and recruited through the Rhodes University Health Care Centre. Using social constructionism, symbolic interactionism and the theory of biographical disruption, the narratives revealed a positive and inspirational side of living with HIV and AIDS – especially emphasizing that PLWHA do not have to surrender to the deadly narrative of the disease. It became evident that stigma, both internal and external, largely influences illness narratives. Furthermore, the study revealed the social reconstruction of life narratives both in order to understand the illness in terms of past social experiences and to reaffirm the impression that life has a course and the self has a purpose. All participants found that accessing treatment from the Rhodes University Health Care Centre positively influenced their experiences of adherence and reconstruction of narratives. The study indicates that HIV-related interventions in place at the university need to pay more attention to the psychosocial needs of PLWH, involvement of PWLH, as well as keeping up with the continuously changing global HIV narrative. The study argues for more attention to in-depth experiences and personal narratives in HIV and AIDS, and PLWHA education at Rhodes University.
A critical analysis of how the potential of Dynamic Geometry Software as a visualisation tool may enhance the teaching of Mathematics
Authors:   , Mavani Beena Deepak
Published: April 2021

Visualisation in the mathematics classroom has its own pedagogical value and plays a significant role in developing mathematical intuition, thought and ideas. Dynamic visualisation possibilities of current digital technologies afford new ways of teaching and learning mathematics. The freely available GeoGebra software package is highly interactive and makes use of powerful features to create objects that are dynamic, and which can be moved around on the computer screen for mathematical exploration. This research study was conceptualised within the GeoGebra Literacy Initiative Project (GLIP) – an ICT teacher development project in Mthatha in the Eastern Cape, South Africa. The focus of this study was on how GeoGebra could be used as a teaching tool by harnessing its powerful visualisation capacity. In the study, selected GLIP teachers collaboratively developed GeoGebra applets, then implemented and evaluated them. The research methodology took the form of action research cycles in which the design, implementation and evaluation of successive applets determined the data gathering and analysis process. My data consisted mainly of recorded observations and reflective interviews. The underlying theoretical foundation of this study lies in constructivism, which aligned well with the conceptual and analytical framework of Kilpatrick et al.’s (2001) description of teaching proficiency. An in-depth analysis of my classroom observations resulted in multiple narratives that illuminated how teachers harnessed the visualisation capabilities inherent in the software. My findings showed that dynamic visualisation and interactivity afforded by the use of technology are key enabling factors for teachers to enhance the visualisation of mathematical concepts. My analysis across participants also showed that technical difficulties often compromised the use of technology in the teaching of mathematics. The significance of this research is its contribution to the ongoing deliberations of visualisation and utilisation of technological resources, particularly through the empowerment of a community of teachers. The findings recognised that the integration of technology required appropriate training, proper planning and continuous support and resources for the teaching of mathematics. This action research provided insightful information on integrating Dynamic Geometry Software (DGS) tools in mathematics classrooms that could be useful to teachers and curriculum planners.
Conceptualisations and pedagogical practices of academic literacy in Namibian higher education
Authors:   , Julius Lukas Homateni
Published: April 2021

The purpose of this study was to investigate academic literacy development lecturers’ conceptualisations of academic literacy and resultant pedagogical practices in academic development courses at three different Higher Education Institutional types in Namibia. The research sites were a Traditional University, a University of Technology and a Comprehensive University. The focus was to understand the extent to which the academics’ conceptions of academic literacy and the resultant pedagogical practices in the academic development courses at these three Higher Education Institutions (HEIs) facilitate epistemological access into students’ chosen fields of study. Bernstein’s Pedagogical theory (1990), Genre theory (1996) and Halliday’s Systemic Functional Linguistics (1978) were used as the study’s theoretical lenses and analytical framework. An interpretative paradigm and a qualitative case study design were employed as the research approach. Semi-structured interviews, classroom observations and documentary evidence were used to generate data. Research findings revealed a common (mis)conception of the nature of academic literacy, the resultant inadequate learning support offered to students in the selected academic literacy development courses, and a clear divorcing of academic literacy interventions from the students’ ‘home’ or mainstream disciplines at the three HEIs. The participants understood academic literacy from an autonomous position as a set of generic skills which could be taught outside of mainstream classes. Moreover, findings revealed that this understanding impacted on the design and assessments of all the academic literacy courses across the three universities under study. The study calls for a context sensitive model through which academic literacy acquisition can be scaffolded to meet the discipline-specific epistemological needs of the students.
The association between cognitive biases and the quality of strategic decision making: Evidence from Jordanian banks
Authors: Jarrar Ayman
Published: April 2021

Excellence in strategic decision making is the driving force behind successful strategy adoption and implementation. However, it is becoming more and more complex as businesses emerge in unpredictable environments and conditions. The main objective of this study is to investigate the impact of cognitive bias and its dimensions (the illusion of control, prior hypothesis bias, escalating commitment bias and representativeness, and availability bias) on strategic decision making. In terms of methodology, the study used a random sampling technique. The study applied a survey as a research tool distributed among 138 bankers (employees at the managerial level) in managerial and administrative positions. Further, descriptive analysis and regression analysis were used to analyze the data and test hypotheses. The results show a positive and significant effect of the illusion of control and representativeness. The results show that the illusion of control, prior hypothesis bias, escalating commitment bias and representativeness, and availability bias significantly impact the strategic decision-making in Jordanian banks. It is concluded that the null hypothesis will be accepted and, therefore, the alternative hypothesis will be rejected based on the significant levels for the primary and secondary hypotheses. The factors of the escalating commitment bias, the availability bias, and the reasoning by analogy were not significant. Finally, the study recommends developing more literature on integrating psychology and discrimination and applying the research to different industries and managerial levels.

Authors: Kurlaev Petr P. , Gritsenko Viktor A. , Belozertseva Yuliya P.
Published: April 2021

Objective: to identify predictors of an unfavorable course of the wound process in the postoperative period in patients with purulent-necrotic complications (PNC) of neuropathic and neuroischemic forms of diabetic foot syndrome (DFS). Materials and methods. A comparative analysis of anamnestic, clinical, laboratory, and microbiological parameters of 40 patients with PNC of DFS, divided into 2 statistically homogeneous opposition groups of 20 patients each. Studies were conducted at the time of admission of patients to the hospital and 3-5 days after surgical treatment. In patients of the 1 (main) group with an unfavorable course of the wound process in the postoperative period, there was a need for repeated surgical interventions, and in patients of the 2 (compared) group, wound healing occurred after a single radical surgical aid. Results. Preoperative biomarkers of unfavorable course of wound process in patients with PNC of DFS were: age less than 60 years, treatment with insulin before admission, the lesion of the foot tissue of 4-5 degree (according to Wagner), the persistence of pulsation at a. dorsalis pedis, contamination of the wound by Pseudomonas aeruginosa or Staphylococcus aureus with gram-negative bacteria, resistance of the wound microflora to cephalosporins. In the postoperative period on the 3-5 days the patients of the main group significantly more often developed the following signs: hyperthermia >37.5°C, hypoalbuminemia <35 g/l, hyperglycemia >10 mmol/l and local signs of inflammation in the affected foot area, such as pain, edema, hyperemia, inconsistency of sutures, wet necrosis and purulent discharge from the wound, as well as detection of P. aeruginosa or enterobacteria. Conclusion. The identified biomarkers can be used to develop a model for predicting the unfavorable course of the wound process in the postoperative period in patients with PNC of neuropathic and neuroischemic forms of DFS which, in turn, will allow optimizing surgical tactics and timely adjusting the conservative therapy regimen.
Possibilities for forecasting and preventing early postoperative complications
Authors: Saraev Igor A. , Mishustin Vladimir N.
Published: April 2021

Objective. The article provides information on how to improve the forecast of the early postoperative period by additional individualization of anesthetic management of patients during emergency surgical interventions on the gallbladder using artificial neural network technologies. Materials and methods. The course of combined anesthesia and the features of the postoperative period were analyzed in 92 patients with an endoscopic cholecystectomy performed for urgent indications. The prediction of the variant of the postoperative stage of hospitalization was realized using the analysis of the significance of 20 different-modal variables selected for the description of patients using fuzzy logic technologies. The possibility of changing the forecast to a more favorable one was achieved on the basis of the developed algorithm for evaluating the results of training neural networks on the Neuro Pro 0.2 neuroimitator. Results. According to the generally accepted criteria, all patients had endoscopic cholecystectomy and anesthesia wit out complications. At the postoperative stage, 2 groups of persons were identified - with the expected short hospitalization (72 cases - 6.7±2.1 days) and with the clinic, which led to its reliable prolongation (20 cases - 12.2±3.5 days). It has been shown that the use of a neural network approach makes it possible with a confidence of more than 80% to assume cases with a high probability of postoperative disorders and in half of such patients to improve the prognosis within the framework of neural network technology and the developed algorithm for selecting the severity of the selected 5 variable factors related to the method of conducting anesthesia. Conclusion. Neural network technology makes it possible to predict cases with individual “unpredictable” responses to surgical trauma. Assessing the significance of the factors used and varying their severity create the basis for the individualization of anesthetic management of patients, prevention of postoperative reactions and a reduction in the period of hospitalization.
Modification in energy and productivity of high-temperature variable pressure humidification–compression
Authors: Abedi Marzieh , Ghalavand Younes
Published: April 2021

One of the important approaches in thermal desalination processes is consumed energy reduction. To achieve this aim, three arrangements of humidification–compression (HC) processes are designed. Two single-stage processes and one double-stage HC process are designed and their performances are compared based on desalinated water production, gained output ratio (GOR) and power consumption. An attempt is made to reduce the power consumption and improve the system performance. All three processes are simulated to examine the effect of operation parameters on HC performance. To validate these simulations, the theoretical results are compared with an experimental rig with a humidifier column of 1.5 m height. The results indicate that the simulation values conform to the experimental data. The effect of minimum approach temperature (ΔTmin) on system performance is investigated for three processes subject to constant operating conditions (feed temperature, water mass flow, air mass flow, and pressure ratio). For this purpose, four values of ΔTmin are considered (7.5, 10, 12.5 and 15 °C) for heat exchanger operations. The results indicate that an increase in ΔTmin in all three cases increases desalinated water volume and GOR. Also, the double-stage HC system has higher water production rate (66.08 kg/h) and higher GOR (17.19) compared with its counterparts.

Authors: Liu Xinliang , Yin Hailiang , Zhao Jian , Guo Ziqi , Liu Zhen , Sang Yizhou
Published: April 2021

Coagulation kinetics and floc properties are of great fundamental and practical importance in the field of water treatment. To investigate the performance of Fe(VI) and Fe(III) salt on particle coagulation, Malvern Mastersizer 2000 was employed to continuously and simultaneously monitor the kaolin floc size and structure change, and population balance modeling was used to investigate the coagulation mechanism. The results show dosage increase had positive effect on collision efficiency and floc strength and negative effect on restructure rate. Low shear rate resulted in higher collision efficiency and stronger floc. Low water temperature had a pronounced detrimental effect on coagulation kinetics. Temperature increase showed the most significant positive effect on collision efficiency, floc strength and restructure rate. The optimum pH zone for the coagulation was found to be between 6 and 8. Further pH increase lowered the collision efficiency and floc strength and increased the restructure rate. FeCl3 resulted in a larger ratio of the mass to volume of kaolin flocs (compactness) than those induced by ferrate.
Review of the hydraulic capacity of urban grate inlet: a global and Latin American perspective
Authors: Cárdenas-Quintero M. , Carvajal-Serna F.
Published: April 2021

The most recent numerical models of urban drainage allow the integration of runoff from roads with the network of sewer pipes, thus evolving towards a holistic version of the system. A fundamental part of this integration is the capture of stormwater in urban drain inlets. These studies have recently increased, resulting in different methodologies to represent the uptake process and making it difficult to apply unified or general formulations. Therefore, this document intends to be a review of the most representative experimental and numerical studies on the capture of rainwater through grates. In addition, the review includes the proposed methodologies for estimating the flow captured by urban storm drains to define a starting point for new and complementary studies to be carried out by researchers, manufacturers, and operators involved in public drainage service systems. Particularly in Latin America, research on the subject is limited even though it is a highly urbanized region. In this context, this document has an additional interest in presenting a particular analysis of the concept of urban drainage in Latin American cities.

Published: April 2021

Os anos de 1970 tem como marco histórico o início do processo de formação de professores indígenas, formando monitores bilíngues. A partir da Constituição de 1988 e do Decreto nº 26 de 1991, a política da educação escolar indígena passa a ser de responsabilidade do Ministério da Educação, possibilitando a formulação de uma vasta legislação específica para esta modalidade de ensino, entre elas Diretrizes que definem e orientam programas e cursos específicos para a formação de professores indígenas. Nesse texto, cujo objetivo é analisar os avanços e desafios para a formação inicial de professores indígenas, apresentamos as ações desenvolvidas no estado do Paraná para essa política, a partir de pesquisa qualitativa e quantitativa de cunho bibliográfico e documental. Verificamos que o estado tem avançado, entretanto, ainda há necessidade de aumentar os números de professores formados em nível superior para atuar nas escolas indígenas, bem como a oferta de licenciaturas específicas e interculturais que possibilitem a formação integral do sujeito indígena em seus aspectos de territorialidade, cultura, língua, metodologias, concepções de ensino e de aprendizagem que considerem os modos próprios de aprender, inter-relacionados com os etnosaberes.
Formação docente para bacharéis: possibilidades para professores novatos
Authors: Souza Daniela Maysa de , Backes Vânia Marli Schubert , Medina Moya José Luis , Lazzari Daniele Delacanal
Published: April 2021

Muitos profissionais inserem-se precocemente na docência e em muitos casos, apresentando despreparo pedagógico. O artigo objetiva refletir sobre o professor considerado novato e seu processo de formação docente. Este estudo de reflexão teórica teve como questões norteadoras: como constitui-se um docente novato? Quais os principais dilemas enfrentados por este? Como a formação docente pode auxiliar em suas situações problemáticas? Os resultados sugerem que a possibilidade de formação formal seja amplamente considerada e que propostas de formação docente utilizem estratégias para além daquelas que estimulam unicamente a reflexão sobre a própria prática docente. Podem auxiliar, mas não substituir a formação, neste processo: observação da prática dos colegas e aprendizagem horizontal com os pares, uso do portfólio reflexivo, estudos colaborativos, como Lesson Study, criação de comunidades de prática e adoção do período de indução profissional. Reiteramos como imprescindível o apoio institucional. A partir destas reflexões, intencionamos contribuir para a prática docente, salientando que estratégias de formação docente são parte de um amplo processo de formação.

Published: April 2021

Background:

Formulation of topical products for skin delivery that fulfill good formulation
criteria has always been a challenge for pharmaceutical scientists. Despite the challenges, gelbased
drug delivery offers some advantages such that it is non-invasive, painless, involves avoidance
of the first-pass metabolism, and has satisfactory patient compliance.

Objectives:

In this study, C. odorata gel and quercetin gel (bioactive flavonoid compound) were
successfully formulated and compared with placebo and conventional wound aid gel. The chromatographic
profiling was conducted to screen the presence of phytoconstituents. Subsequently, all
formulated gels were evaluated for physical characteristics and stability.

Methods:

Reverse Phase High-Performance Liquid Chromatography (RP-HPLC) of C. odorata
methanolic leaves extract showed a distinct compound separation at a retention time of 8.4min to
34.8 min at 254nm. All gels were characterised by evaluating their rheological properties, including
storage modulus, loss modulus, and plastic viscosity. Besides, texture analysis was performed
to measure the firmness, consistency, cohesiveness, and viscosity index of the gels.

Results:

According to the results, C. odorata gel demonstrated better spreadability as compared to
the other gels, which required less work and was found to be favourable for application on the skin.
Moreover, C. odorata gel showed no changes in organoleptic properties and proven to be stable after
30 days of accelerated stability study at 40°C ± 2°C with Relative Humidity (RH) of 75% ± 5%.

Conclusion:

C. odorata gel was found to be stable, reflecting the combination of materials used in
the formulation, which did not degrade throughout the study. This work suggests the potential of
this gel as a vehicle to deliver the active ingredients of C. odorata to the skin, which can be further
explored as a topical application for antimicrobial wound management or other skin diseases study.

Authors: Heidari Zahra , Tajbakhsh Amir , Gheibihayat Seyed M. , Moattari Afagh , Razban Vahid , Berenjian Aydin , Savardashtaki Amir , Negahdaripour Manica
Published: April 2021

Background:

Viral respiratory infections could result in perturbation of the gut microbiota
due to a probable cross-talk between lungs and gut microbiota. This can affect pulmonary
health and the gastrointestinal system.

Objective:

This review aimed to discuss the impact of probiotics/prebiotics and supplements
on the prevention and treatment of respiratory infections, especially emerging pathogens.

Methods:

The data were searched in PubMed, Scopus, Google Scholar, Google Patents, and
The Lens-Patent using keywords of probiotics and viral respiratory infections in the title, abstract,
and keywords.

Result:

Probiotics consumption could decrease the susceptibility to viral respiratory infections,
such as COVID-19 and simultaneously enhance vaccine efficiency in infectious disease
prevention through the immune system enhancement. Probiotics improve the gut microbiota
and the immune system via regulating the innate system response and production of anti-inflammatory
cytokines. Moreover, treatment with probiotics contributes to intestinal homeostasis
restitution under antibiotic pressure and decreasing the risk of secondary infections due to
viral respiratory infections. Probiotics present varied performances in different conditions;
thus, promoting their efficacy through combining with supplements (prebiotics, postbiotics,
nutraceuticals, berberine, curcumin, lactoferrin, minerals, and vitamins) is important. Several
supplements reported to enhance the probiotics’ efficacy and their mechanisms as well as probiotics-
related patents are summarized in this review. Using nanotechnology and microencapsulation
techniques can also improve probiotics’ efficiency.

Conclusion:

Given the global challenge of COVID-19, probiotic/prebiotic and following nutritional
guidelines should be regarded seriously. Additionally, their role as an adjuvant in vaccination
for immune response augmentation needs attention.

Solar energy is an attractive renewable energy source across the globe that can help overcome the energy crises and has the ability to replace conventional resources. Hybrid solar cells have higher conversion efficiency. In the current chapter the research related to the carbon nanotubes, organic and inorganic solar cell, dye-sensitized solar cells and tandem solar cells are reviewed. The organic solar cells are most suitable and economic, but it has low efficiency of up to 15%. The inorganic solar cells are very expensive and have high efficiency of up to 46% and are used in space applications. The hybrid solar cell is the third type and the perovskite tandem has already proven to be quite efficient (17%) and low cost, mostly because of the cheap materials that are being used.
Semantic deviation in Arabic and English proverbs of love
Authors: Hashem Zahraa Abed , Muhi Thulfiqar Hussein
Published: April 2021

Proverbs are a type of idiomatic expressions that are commonly used in everyday spoken language. They concisely and figuratively summarize everyday experiences and common observations (Borowska, 2014). The proverbs of love often contain various stylistic features that are worthy of analysis. The present paper hypothesizes that semantic deviations in the Arabic and English proverbs of love facilitate pleasurable and enjoyable delivery of the didactic messages conveyed by these proverbs and maximize their persuasive effects. Semantic deviations (such as simile, metaphor, metonymy and synecdoche) represent an important type of stylistic deviation in proverbs because of their figurative features and aesthetic values. Such stylistic devices make the content of these proverbs more appealing the audience and maximize the persuasive effect of their contents. This study examined 50 proverbs of love (25 in each language) from stylistic perspective, based on the semantic deviation model developed by Leech (1969). The analysis showed that the extensive use of various types of semantic deviations maximize the persuasive effects, and eventually efficient transmission of cultural wisdom. Additionally, such deviations were found to reinforce and facilitates the pleasurable delivery of the didactic function of proverbs.

Published: April 2021

Изучены состав, эмиссионные и оптические свойства монокристаллов CdS с поверхностной пленкой Ва толщиной Theta от 0.5 до 5 монослоев. Установлено, что с ростом Theta до 1 монослоя глубина зоны выхода истинно-вторичных электронов (и фотоэлектронов) λ существенно увеличивается, что объясняется уменьшением работы выхода. При дальнейшем росте Theta значения λ и интенсивность фототока уменьшаются. Показано, что при комнатной температуре не происходит заметной взаимодиффузии атомов на границе Ва-CdS. После прогрева при T=700 K происходит интенсивная диффузия S в пленку Ba и образуется соединение типа Ba2S. Ключевые слова: зона выхода электронов, адсорбция, профили распределения атомов, эмиссионная эффективность, работа выхода.

A multilayer heteronanostructure consisting of three pairs of amorphous silicon and amorphous germanium (a-Ge/a-Si:H) layers grown on a silicon substrate by low-frequency plasma-chemical deposition at temperature 225 oC was investigated. From the analysis of the Raman spectra, the phase composition of the silicon and germanium layers was determined, which showed that the layers are completely amorphous. The transmittance electron microscopy images show vertically ordered amorphous Ge nanoclusters initiated by local inhomogeneities in the first germanium layer, the lateral dimensions of which increase from the lower to the upper layer.

Radiation damage to isolated glycyl-leucine (C8H16N2O3) molecules caused by interaction with He2+ ions was studied. For the first time, the relative cross sections of the main processes of changes in the charge state of the collision partners and the relative cross sections of the fragmentation processes of singly and doubly charged molecular ions formed during single collisions of glycyl-leucine molecules with ions have been obtained. The optimized geometry of the molecule and singly charged glycyl-leucine ion was calculated using the density functional theory (DFT).

An experimental study of the behavior of laser ultrasonic signals near a hole in a plate from dielectric silicon nitride ceramics under the action of external compressive stresses is carried out. A fundamental discrepancy between the results obtained and similar results obtained by us earlier for metals and a quantitative discrepancy with the predicted thermodynamic model of the formation of thermoelastic signals from stressed materials is shown. An explanation of the observed discrepancies is proposed using the model of thermal excitation of lattice defect states that we proposed earlier.

Clinicians spend a substantial part of their workday reviewing and writing electronic medical notes. Here we describe how the current, widely accepted paradigm for electronic medical notes represents a poor organizational framework for both the individual clinician and the broader medical team. As described in this viewpoint, the medical chart—including notes, labs, and imaging results—can be reconceptualized as a dynamic, fully collaborative workspace organized by topic rather than time, writer, or data type. This revised framework enables a more accurate and complete assessment of the current state of the patient and easy historical review, saving clinicians substantial time on both data input and retrieval. Collectively, this approach has the potential to improve health care delivery effectiveness and efficiency.

Pemberian obat dengan dosis sesuai pada pasien Chronic Kidney Disease  (CKD ) penting dilakukan, salah satunya untuk memastikan luaran terapi obat yang optimal. Penelitian ini bertujuan mengetahui hubungan antara dose adjustment obat dan luaran terapi serta efisiensi biaya terapi obat dengan adanya dose adjustment pada pasien rawat inap dengan CKD.Jenis penelitian ini observasional dengan desain cross sectional. Sebanyak 200 rekam medis pasien rawat inap dengan CKD periode Januari – Desember 2017 di RSUD dr. Soeselo dan RSUD Suradadi Kabupaten Tegal dilibatkan dalam penelitian ini. Dose adjustment dihitung berdasarkan fungsi ginjal pasien, yang diestimasikan dengan laju filtrasi glomerular menggunakan formula Cockcroft-Gault. Hubungan antara dose adjustment obat dan luaran terapi menggunakan analisis Chi-square.Hasil penelitian menunjukkan terdapat 1882 obat yang diresepkan, 338 (17,93%) obat memerlukan dose adjustment pada pasien CKD. Dari  obat tersebut, 175 (51,78%) obat diberikan dengan dose adjustment,  sejumlah 118 (67,43%) obat menghasilkan luaran terapi membaik , 23 (15,52%)  obat tidak membaik  dan 34 (19,43%) obat tidak dapat dievaluasi. Sedangkan dari 163 obat tanpa dose adjustment, 103 (63,19%) obat menghasilkan luaran terapi membaik dan 40 (24,54%) obat tidak membaik dan 20 (12,27%) obat tidak dapat dievaluasi. Terdapat hubungan yang signifikan antara dose adjustment dengan luaran terapi obat pada pasien rawat inap dengan CKD (OR 1,922, 95% CI = 1,119-3,548, p= 0,018). Efisiensi biaya yang dapat dihasilkan dengan adanya dose adjusment pada penelitian ini sebesar Rp. 1.620.588,00.

Penelitian terdahulu menunjukkan bahwa fraksi ke-6 (F6) merupakan fraksi aktif (F-akt) daun Tithonia diversifolia (Hemsley) A.Gray yang menghambat pertumbuhan Plasmodium. Pertumbuhan parasit ini memerlukan energi yang diperoleh dari aktivitas laktat dehidrogenase (LDH). Penelitian ini bertujuan mengkaji aktivitas antiplasmodium fraksi aktif T. diversifolia terhadap kadar LDH kultur P. falciparum. Kultur Plasmodium falciparum strain D10 stadium cincin dibagi menjadi kelompok eritrosit tidak terinfeksi (KTI), eritrosit terinfeksi (KI), dan eritrosit terinfeksi Plasmodium yang diberi F6 (F-akt) T. diversifolia (KI+F-akt) konsentrasi 9,38-150 µg/mL. Kultur diinkubasi 48 jam. Media kultur diukur kadar LDH-nya secara enzimatik. Adanya perbedaan LDH antar kelompok dianalisa dengan Anova. Penghambatan aktivitas LDH (IC50) ditetapkan dengan analisa probit. Kadar LDH kelompok KI (362,33 ± 133,18 U/L) lebih tinggi daripada KTI (270,33 ± 65,85 U/L) (p>0,05). Pemberian F-akt pada KI menyebabkan kadar LDH parasit lebih rendah daripada KI. Kadar LDH parasit yang diberi F-akt konsentrasi 9,38; 18,75; 37,50; dan 150 µg/mL secara berturut-turut adalah 365,5 ± 129,5; 210,5 ± 1,5; 195,5 ± 81,5; dan 111,5 ± 53,5 U/L. Tidak ada perbedaan kadar LDH antar kelompok penelitian (p>0,05). F-akt  T. diversifolia mampu menghambat LDH P. falciparum strain D10 dengan nilai IC50 = 39,22 µg/mL.Kata kunci: Tithonia diversifolia, laktat dehidrogenase, Plasmodium falciparum
Pengaruh kombinasi Superdisintegrant Crospovidone dan Croscarmellose Sodium pada sifat fisik dan disolusi Fast Disintegrating Tablet Hidroklorotiazid

Published: April 2021

Hidroklorotiazid (HCT) merupakan obat lini pertama untuk penanganan hipertensi. HCT memiliki kelemahan terkait bioavailabilitasnya yang rendah dan umumnya tersedia dalam bentuk sediaan tablet konvensional sehingga dapat menimbulkan masalah tersendiri bagi pasien yang tidak mampu menelan tablet. Fast disintegrating tablet (FDT) HCT merupakan tablet yang dapat terdisintegrasi dan terdisolusi dengan cepat di dalam mulut yang memungkinkan obat dapat diabsorpsi di daerah pregastric sehingga meningkatkan bioavailabilitas obat. Penelitian ini bertujuan untuk mendapatkan formula FDT HCT yang menghasilkan sifat fisik optimum dengan kombinasi superdisintegrant crospovidone (CP) dan croscarmellose sodium (CCS). FDT HCT diformulasikan menggunakan kombinasi superdisintegrant CP:CCS pada rentang konsentrasi CP 2-6% dan CCS 1-5%. FDT dibuat dengan metode kempa langsung. Tablet FDT yang dihasilkan, dilakukan uji sifat fisik tablet yaitu kekerasan, kerapuhan, waktu disintegrasi, waktu pembasahan, rasio absorpsi air, dan uji disolusi. Data diolah dengan metode simplex lattice design menggunakan software Design Expert® untuk memprediksi formula optimum. Hasil penelitian menunjukkan bahwa  CP berpengaruh signifikan dalam mempercepat waktu pembasahan, waktu disintegrasi, dan disolusi tablet, sedangkan CCS berpengaruh signifikan dalam menurunkan kekerasan, meningkatkan kerapuhan dan rasio absorpsi air.
