SIMULATION OF WIRELESS ESTIMATION BANDWIDTH FOR NETWORK TECHNOLOGY
Authors: WAN ABU BAKAR WAN AEZWANI , CHE WAIL CHE MUHAMMAD FAIZUL , MAN MUSTAFA
Published: September 2022

Wireless estimation bandwidth is used in path selection for a network environment. To access the internet, a typical user shares the same bandwidth that has been provided by the Internet Service Provider (ISP). The scenario worsens when a few of the users access multimedia content on the Internet which requires high bandwidth at the same time. This research could be enhanced in other different network environments, such as wired and mobile phone environments, and represents an analysis of ready bandwidth using a few wireless bandwidth estimation tools, which are WBest, Pathload, IGI MRTG, PRTG and PTR. This paper attempts to design and develop a detection mechanism for wireless estimation bandwidth to estimate an available bandwidththrough several sending of injection traffic packets to the server. In this paper, we measured available bandwidth with WBest. Then we analysed the estimation measurements prior to 2 simulations done on Wireless Mode 11 Mbps 802.11b and Wireless Mode 54 Mbps 802.11g. Three different percentages of packet injection (0%, 25%, 50%) were tested on Wireless Mode 54 Mbps 802.11g. The results accuracy shows that the 50% packet injection performs the least available bandwidth compared to the injection of 0% and 25% of packets.

In addition to the mentioned systems, the project also included a system of protection against atmospheric discharges and a complete video surveillance system on a given plot.
Analysis of the Influence of Active Parts of the Power Transformer on the Propagation of Signals from Source of Partial Discharges to UHF Sensors
Authors: Dukanac Đorđe
Published: September 2022

Partial discharges caused by initial weaknesses in the insulation system of the power transformer cannot be completely ignored, because they can warn in advance of possible serious deficiencies, which in the worst cases could cause irreversible failure of the power transformer. Monitoring of partial discharge signals using UHF sensors during power transformer operation enables their processing in order to determine the main properties of recorded partial discharge signals (e.g. amplitude, repetition rate, frequency range) to prevent power transformer failure. Using simulations in ANSYS HFSS, this paper investigates the waveforms and delays of UHF electromagnetic signals on UHF sensors mounted at different locations of a small power transformer tank. Electromagnetic waves are emitted by a specially designed model of the source of partial discharges in the insulation of the power transformer. Full-wave electromagnetic simulations are performed on the model of a small power transformer of core construction. The effect of reflections of electromagnetic UHF waves from the walls of the tank is taken into account, then the diffractions of waves around and the reflections of waves from the elements of the three-phase magnetic core and three-phase primary and secondary windings. The simulation is based on finite element method. It is a numerical method that is applied to differential equations with limit values in order to obtain an approximate solution. The source and receiver sensors in the computer simulation are designed with transmitting and receiving UHF antennas, respectively. The advantages and disadvantages of this computer simulation will be described.

Authors: Sum Grace , Kadir Mumtaz Mohamed , Ho Soon Hoe , Yoong Joanne , Chay Junxing , Wong Chek Hooi
Published: September 2022

Introduction: The Patient-Centred Medical Home (PCMH) demonstration in Singapore, launched in November 2016, aimed to deliver integrated and patient-centred care for patients with biopsychosocial needs. Implementation was based on principles of comprehensiveness, coordinated care and shared decision-making.
Method: We conducted a prospective single-arm pre-post study design, which aimed to perform cost analysis of PCMH from the perspectives of patients, healthcare providers and society. We assessed short-to-intermediate-term health-related costs by analysing data on resource use and unit costs of resources.
Results: We analysed 165 participants enrolled in PCMH from November 2017 to April 2020, with mean age of 77 years. Compared to the 3-month period before enrolment, mean total direct and indirect participant costs and total health system costs increased, but these were not statistically significant. There was a significant decrease in mean cost for primary care (government primary care and private general practice) in the first 3-month and second 3-month periods after enrolment, accompanied by a significant decrease in service utilisation and mean costs for PCMH services in the second 3-month period post-enrolment. This suggested a shift in resource costs from primary care to community-based care provided by PCMH, which had added benefits of both clinic-based primary care and home-based care management. Findings were consistent with a lower longer-term cost trajectory for PCMH after the initial onboarding period. Indirect caregiving costs remained stable.
Conclusion: The PCMH care model was associated with reduced costs to the health system and patients for usual primary care, and did not significantly change societal costs.

Authors: Camacho Lazarraga Pablo
Published: September 2022

Se realiza un análisis de la utilización de las estrategias de enseñanza incidentales para el aprendizaje de las habilidades en el baloncesto. Para ello, se utiliza la estructura de la metodología DAFO (debilidades, amenazas, fortalezas y oportunidades), que ha demostrado ser una técnica eficaz para analizar y formular nuevas estrategias de acción. Hemos realizado una evaluación interna y externa, recopilando, analizando, interpretando e identificando algunos elementos que consideramos se deberían tener en cuenta en investigaciones futuras, aprovechando las fortalezas y oportunidades y minimizando las amenazas y debilidades detectadas que pudieran favorecer o limitar la generalización de los resultados obtenidos, con objeto de avanzar en el entendimiento del efecto de la configuración de determinadas variables sobre el comportamiento de los jugadores, aumentando la eficacia del proceso de enseñanza-aprendizaje a través de la mejora del diseño de nuestras tareas. Analizamos dichos elementos y realizamos una comparación de la tendencia del efecto de las tareas desarrolladas en los estudios que utilizan dichas estrategias de enseñanza (n=124), fundamentalmente de naturaleza inespecífica, con un estudio realizado de corte ecológico donde se desarrollan tareas específicas (n=1). En líneas generales, los resultados de nuestro estudio evidencian la importancia de que los jugadores dispongan de ambos tipos de procesamiento, reflexivos e intuitivos. Finalmente, consideramos que el análisis DAFO puede aportar una visión más amplia en el campo de la investigación del entrenamiento deportivo, actuando como complemento en el análisis de los principios que rigen el diseño de las tareas.

Authors: Sá Carla , Vilar Jorge , Magalhães Pedro , Vasques Catarina
Published: September 2022

This study aims to evaluate the sedentary behavior, caloric content of snacks and sleep time of preschool children in two different regions of Portugal (Bragança and Gondomar). Participated in this study 230 healthy preschoolers (103 girls; 127 boys), of which 176 (76.5%) were from Bragança (mean age of 4.5±0.7 years) and 54 (23.5%) were from Gondomar (mean age of 4.3±1.0 years). A questionnaire about sedentary behavior, sleep time and caloric content of snacks (morning and afternoon) were answer by parents of this preschool children. The principal results of our study indicated that the preschool children slept an average of 9.9 ± 0.9 hours, spent time 1.5 ± 0.8 hours in front of television (TV) during the week, and 2.5 ± 1.5 hours during weekend. Regarding the time spent playing video games, they did 0.6 ± 0.6 hours during the week and 0.9 ± 0.9 hours during the weekend. The children morning snack had an average of 232.7 ± 100.8 kcal and the afternoon snack had an average of 350.4 ± 122.4 kcal. According to the WHO guidelines, the results of this study revealed that preschool children spent less hours sleeping, had more caloric content in the morning and afternoon snacks and spent more time in sedentary behaviors, of what is in the recommendations.  These results also suggest that the children’s slept time is affected by the time they spent watching TV and playing video games.

Published: September 2022

The use of technologies to develop serious games for the enhancement of the abilities in the spectrum of emotional intelligence is of utmost importance and it has led progressively to the appearance of new applications. On the other hand, emotional intelligence is a very important concept that positively affects all areas of our lives. This paper aimed to review to show the current state of the studies that administrate the use of serious games to develop and improve emotional intelligence which is very important for our physical, mental and emotional health. The review included 14 scientific articles that met the inclusion criteria from 2010 until 2021. Our findings showed that serious games can play an important role in cultivating and promoting emotional intelligence skills which in turn results in a better quality of life. Future research on the subject could study and focus more systematically on the importance of serious games in the development of emotional skills in people's daily lives in general. It would be important, in other words, to investigate whether the development of emotional skills through the use of serious games is transferred to a more general context of individuals' personal lives and not just when engaging in the specific activity during the research.

El objetivo de este estudio fue analizar el impacto objetivo y percibido del tipo de evaluación sobre el rendimiento académico de estudiantes de Educación Física bajo un modelo curricular por competencias. Se realizó una investigación de tipo no experimental, de corte transversal, con enfoque de investigación mixto, nivel descriptivo-relacional e interpretativo, con una muestra no probabilística e intencionada, en que participaron 29 estudiantes mediante entrevistas y sobre quienes se obtuvo una base de datos con 2804 registros evaluativos del primer ciclo de la carrera. Los resultados muestran una transición paulatina hacia el uso de técnicas de un tipo de evaluación integradora lo que resulta coherente con el modelo por competencias. Se encontraron diferencias significativas en el rendimiento a favor de esta tipología respecto a las tradicionales, aunque con un tamaño de efecto bajo. Los estudiantes también la valoran positivamente porque permite vincular teoría y práctica, favorece el autocontrol, disminuye la ansiedad, por tanto, se pueden preparar mejor para rendirla, y por ello refleja el rendimiento real. 
Abstract. This research aimed to analyze the objective and perceived impact the type of assessment has on academic performance in Physical Education Teaching program students under a competency-based curriculum model. A non-experimental study was conducted; cross-sectional, with a mixed-research focus, at a descriptive-correlational and interpretative level. A non-probabilistic and purposeful sampling was used; 29 students participated through interviews, and from whom a 2804 assessment register database was obtained regarding the program's first cycle participation. Results indicate a gradual transition towards integrative assessment use, which is coherent with the program's competency model. Significant performance differences were found in favor of this assessment type in contrast with the more traditional ones, though with a low effect size. Students positively value integrative assessment, as it ties theory and practice, encourages self-monitoring and lowers anxiety. Consequently, students can better prepare for testing, reflecting authentic academic performance.

El deporte ha experimentado una gran evolución a lo largo de los años, hecho que se ha manifestado en un incremento de la práctica deportiva, así como también en un aumento de la oferta de instalaciones deportivas. En mercados cada vez más competitivos, la excelencia en la prestación de servicios juega un papel decisivo. Pese a la importancia de dicha temática, no se han encontrado estudios que evalúen la gestión de la política comercial de los centros y clubs deportivos, y en consecuencia tampoco se han hallado instrumentos válidos para tal fin. Por ello, el objetivo de la presente investigación es validar el instrumento TP-SPORTS: una hoja de registro estructurada en ocho dimensiones y noventa variables que permite analizar la gestión de la política comercial de los centros y clubs deportivos. Para la validación de la misma se ha recurrido a una valoración de juicio de expertos, una evaluación inter e intrapersonal mediante la prueba kappa de Cohen y una prueba piloto con 150 alumnos del grado de Ciencias de la Actividad Física y el Deporte. Tras estos pasos, se puede concluir que el instrumento TP-SPORTS manifiesta ser una herramienta innovadora, a la vez que válida para el análisis de la política comercial de los centros y clubs deportivos de nuestro país.
Abstract. Sport has experienced a huge evolution through the years, which is directly reflected on an increase in the population engaged in sport, as well as in the supply of sport facilities. In increasingly competitive markets, excellence in the provision of services plays a decisive role. Despite the importance of this subject, no studies have been found that evaluate the management of the commercial policy of sport centres and clubs and consequently no valid instruments have been found for this purpose. Therefore, the objective of the present research is to validate the TP-SPORTS instrument: a record sheet structured in eight dimensions and ninety variables that allows the analysis of the management of the commercial policy of sports centres and clubs. In order to validate it, an expert judgment assessment, inter and intrapersonal evaluation using Cohen's kappa test and a pilot test with 150 students of the Physical Activity and Sport Sciences degree have been used. In view of the above, it can be concluded that TP-SPORTS instrument proves to be an innovative and valid tool for the analysis of the commercial policy of sports centres and clubs in our country.

Introduction: The sedentary lifestyle in adolescence, combined with unhealthy eating habits, leads to the accumulation of body fat and the development of non-communicable chronic diseases (NCDs). Objective: To investigate the effects of the multidisciplinary project on the anthropometric and body composition responses of adolescents with obesity and to compare the intervention responses according to gender. Methods: forty-eight adolescents aged 12-17 years old were evaluated: [male (n = 19) and female: (n = 29)]. Body mass, height, waist (WC), hip (HC), neck (NC), arm (AC), circumference, and waist-to-hip ratio (WHR) were measured. Body mass index (BMI), BMI z-score, body fat percentage (BF%), fat mass (FM), lean mass (LM), fat-free mass (FFM), skeletal muscle mass (SMM), and visceral fat were evaluated. Body composition was assessed via bioelectrical impedance InBody 570®. Data were compared via paired t-test (comparison between pre- and post-intervention between the adolescents) and a two analysis of variance (ANOVA): comparison between gender in pre- and post-interventions), both assuming pd»0.05 was performed. Results: A time effect was identified with significant reductions in body mass, WC, HC, BMI, BMI z-score, BF%, FM, and visceral fat in the post-intervention period (p<0.05). However, no significant differences were identified for NC, AC, LM, FFM, SMM, and WHR (p>0.05) after the intervention. Conclusion: Multiprofessional interventions effectively improved male and female adolescents’ anthropometric aspects and body composition. However, no differences were observed between them.
Influencia de la Actividad Físico-Deportiva en el rendimiento académico, la autoestima y el autoconcepto de las adolescentes: el caso de la isla de Tenerife (Influence of Physical-Sports Activity on academic performance, self-esteem and self-concept of adolescent girls: the case of the island of Tenerife)
Authors: Vallejo Ana Gaspar , Alguacil Jiménez Mario
Published: September 2022

El estudio analiza la actividad físico deportiva (en adelante AFD) de 632 chicas adolescentes de la isla de Tenerife, pertenecientes a 68 centros educativos. El objetivo, además de conocer dichos hábitos, fue comprobar la influencia que estos ejercen en su rendimiento académico, su autoestima y su autoconcepto. Los datos fueron recogidos a través del Cuestionario Internacional de Actividad Física (IPAQ), la adaptación del cuestionario de autoconcepto físico para jóvenes (C-PSQ) y el cuestionario AF5. Los resultados confirman la influencia de la AFD en las variables comentadas, la relación entre los hábitos deportivos de los padres y madres y los de las hijas, la disminución de la práctica de AFD en la adolescencia frente a la infancia y la existencia de actividades que siguen marcadas por estereotipos de género. Esta información puede ser útil para desarrollar políticas deportivas públicas más adecuadas, que fomenten la AFD, reduzcan el abandono y sirvan para romper con los estereotipos de género, ofreciendo alternativas que permitan crear y consolidar hábitos deportivos saludables.
Abstract. The study analyzed the physical sports activity (hereafter PSA) of 632 adolescent girls from the island of Tenerife, belonging to 68 educational centers. The objective, besides knowing these habits, was to check the influence of these habits on their academic performance, self-esteem and self-concept. The data were collected through the International Physical Activity Questionnaire (IPAQ), the adaptation of the physical self-concept questionnaire for young people (C-PSQ) and the AF5 questionnaire. The results confirm the influence of PSA on the aforementioned variables, the relationship between the sports habits of fathers and mothers and those of daughters, the decrease in the practice of PSA in adolescence compared to childhood, and the existence of activities that continue to be influenced by gender stereotypes. This information can be useful for developing more appropriate public sports policies that encourage PSA, reduce dropouts and contribute to breaking gender stereotypes, offering alternatives that allow the creation and consolidation of healthy sports habits.

Authors: Azevedo Eugénia Lopes , Mesquita Isabel Ribeiro , Araújo Rui Flores
Published: September 2022

Research has shown an increased attention towards Reflective Practice as a successful aspect in the professional development of Physical Education Teacher Education. Notwithstanding, there is a lack of empirical research about how teachers’ reflective skills should be developed in this context. The aim of this systematic review was to understand what and how has been studied about physical education teachers’ reflective skills, and how such strategies can be further developed and refined in Physical Education Teacher Education. Following Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) (Page et al., 2021) six databases were included to ensure that all relevant data was considered, and criteria scales were adapted in order to access studies’ quality. The results show the importance of incorporating meticulously planned and organized practicum in teachers’ training of reflective skills. Despite the importance of collaborative work in reflective skills development, there is a need to perform a deeper examination of those which contribute to improve reflective skills and how teachers develop reflection in collaborative settings, such as through the examination of communities of practice. Besides, writing reflections and video-taped classroom situations can enhance teachers’ reflective skills, although supervision is required. This review highlights the important yet challenging role of teachers’ reflective skills investigation, in order to achieve a deeper understanding of the contexts and strategies through which this issue is developed.

Published: September 2022

El aumento de las tasas de supervivencia en unidades de cuidados intensivos (UCI) ha conllevado el incremento de pacientes que sufre el denominado síndrome de debilidad adquirida en UCI. Para el cual no ha tratamiento específico actualmente. Este síndrome provoca múltiples secuelas clínicas y repercute en la esfera bio-psico-social del paciente. En su etiología figuran alteraciones fisiopatológicas diversas, así como numerosos factores de riesgo. Entre los factores de riesgo, uno de los más importantes es la inmovilización prolongada. Por lo que la rehabilitación temprana en UCI se alza como arma fundamental para combatir este síndrome. La identificación precoz es fundamental para iniciar la terapia lo antes posible, evitando así incrementar la duración esta patología. Numerosos estudios han intentado demostrar la evidencia de aplicar estrategias rehabilitadoras precoces, y son los que aquí se manifiestan.
Abstract: The increase in survival rates in intensive care units (ICU) has led to an increase in patients suffering from the so-called ICU-acquired frailty syndrome. For which there is currently no specific treatment. This syndrome causes multiple clinical sequelae and affects the bio-psycho-social sphere of the patient. Its etiology includes various pathophysiological alterations, as well as numerous risk factors. Among the risk factors, one of the most important is prolonged immobilization. Therefore, early rehabilitation in the ICU stands as a fundamental tool to combat this syndrome. Early identification is essential to start therapy as soon as possible, thus avoiding increasing the duration of this pathology. Numerous studies have tried to demonstrate the evidence of applying early rehabilitative strategies, and they are the ones that are manifested here.
Alterações no intestino anterior durante a metamorfose da abelha Apis mellifera (Hymenoptera: Apidae): origem do proventrículo
Authors:   ,   Universidade Federal de Viçosa, Guedes Daniela de Castro
Published: September 2022

Abelhas são insetos holometábolos, passando assim por uma complexa mudança corpórea durante a metamorfose. Além disso, são insetos bem-sucedidos evolutivamente, e parte desse sucesso se deve a variedade fisiológica e estrutural de seu trato digestório, que é dividido em três porções anatomicamente distintas: intestino anterior ou estomodeu, intestino médio ou ventrículo e intestino posterior ou proctodeu. O intestino posterior tem como função o equilíbrio osmótico e excreção, o intestino médio é simples morfologicamente, porém é complexo funcionalmente, sendo este o principal sitio de digestão e absorção de nutrientes. No intestino anterior ocorre a passagem e o armazenamento do alimento. Este, segundo Cruz-Landin (2009), não sofre uma metamorfose real no sentido de degeneração, o que ocorre de fato é uma diferenciação seguida de uma reorganização celular, ocorrendo assim um alongamento dessa porção do intestino e a formação do papo e do proventrículo. O proventrículo é o segmento final do intestino anterior, situado na transição para o intestino médio. Durante a fase larval o proventrículo está representado apenas pela válvula estomodeal, sendo o bulbo formado durante a metamorfose. O presente estudo buscou investigar os eventos celulares que possibilitam a formação e diferenciação do proventrículo durante a metamorfose de Apis mellifera. As regiões precursoras do proventrículo foram submetidos a análises histológicas e de imunofluorescência para detecção de apoptose, autofagia, proliferação e diferenciação celular. Os dados mostraram proliferação celular ocorrendo nas pré- pupas, nas pupas de olho branco e de olho marrom. Nas pupas de olho rosa não ocorre proliferação, e sim uma intensa diferenciação celular. Morte celular por apoptose ocorre em grande quantidade nas pré-pupas, sendo raras nos outros estágios do desenvolvimento. Pupas de olho preto e adultas não apresentaram células positivas para os anticorpos testados.
Foresight in Agriculture, Food and Nutrition for Planning Freshwater in the Course of Climate Change in Africa
Authors:   Full Professor, Economics and Environment, Integrated Water Resources Management, University of Kinshasa, DR Congo & Director of Postgraduate Studies, Francophone Africa (Online), Ballsbridge University Curacao, The Netherlands, Luwesi Cush Ngonzo
Published: September 2022

Integrated Water Resources Management (IWRM) has been designed as a foresight process for world leaders to solve communities’ issues dealing with water uncertainty in agriculture, food and nutrition as well as other related industries. That is why a Global Water Partnership (GWP) was initiated in 1992 by the United Nations to develop water and place it to the center of the political and economic concerns of the member States with an aim to mobilize resources that are necessary to manage water rationally. A focus was put on more than two billion poor people living without access to adequate potable drinking water, among whom more than three-quarters (¾) of the African populations living in poor areas and unurbanized cities. Predictions show that by the 2050, most of this population will be living in African megacities. This will be amplifying the “3As” of water issues: Water Availability, Accessibility and Affordability. Solving this major crisis in prospect requires foresight, both as a process and an analytical tool to address these key issues in the course of climate change. As a process, foresight involves consultation among stakeholders to ensure socio-political, economic, agro-natural and engineering technological solutions to “Develop and Avail Water to All! “. This process, would later require an evaluation of the feedbacks to and from these proposed solutions and their tools. These may include among other strategies and legislations for water policies; innovative techniques for irrigation (production, storage, transport and distribution of water) and hydro-power generation; Payments for water ecosystems services (PWES); and various management operating systems for risk control and mitigation at the watershed and community levels. However, the uncoordinated efforts of scientists working the climate adaptation, mitigation and amelioration spheres have generated another threat, that of climate intervention in the form of solar Geoengineering. African leaders, thus need foresight to check closely opportunities and dangers arising from these technologies. They require a neutral organization having to conduct rigorous socio-economic and environmental impacts assessments prior to embracing these technologies. That is the only way they may ensure a climatic justice to peasants and farmers so that they can leave a legacy in the agriculture, food and nutrition niche for the next generations

Background: Type 2 diabetes (T2D) is a chronic and progressive condition whose early management is crucial in preventing the occurrence of its chronic degenerative complications. Cystatin C (CysC) is a biomarker that may have a beneficial interest in the early detection of microvascular and macrovascular complications of T2D. Methods: We carried out a cross-sectional analytic study at the National Obesity Center of the Yaounde Central Hospital. We recruited 135 patients with T2D and performed a neurologic physical exam using the Toronto clinical score, a fundoscopy, ECG, ABI, and the following paraclinicals: dosage of serum levels of Cystatin C, lipid profile (with determination of Atherogenic indexes), Creatinine (with calculation of glomerular filtration rate using CKD-EPI formula) and hs-CRP. Results: Prevalences of diabetic retinopathy, nephropathy, neuropathy and PAD were 3.0%, 8.9%, 38.5%, 28.1% respectively. Electrocardiographic signs of myocardial ischemia were present in 5.9 % of the participants. We found 0.3[0.5-0.3] mg/l as median levels of the HDL-cholesterol and 0.9[1.2-0.7] mg/l for LDL-cholesterol. The median value of GFR was 105.7[119,0-85.7] ml/min/1.73m². The median serum CysC level was 0.8[0.9-0.6]mg/l and varied with age (p=0.01), A1C (p=0.016) and high blood pressure (HBP) (p=0.006). There was a relationship between serum CysC and diabetic nephropathy (p=0.01) and neuropathy (p=0.025). There was no significant relationship with diabetic retinopathy (p=0.225), PAD (p=0.169) and ECG signs of myocardial ischemia (p=0.669). Conclusion: Chronic microvascular and macrovascular complications of type 2 diabetes are common and in our study are predominantly represented by diabetic neuropathy and PAD. Serum CysC can be useful in the diagnosis of chronic complications of T2D.

Iron deficiency is the most common cause of anaemia. Over the years, various IV preparations of iron have been developed, including Monofer® (Iron isomaltoside 1000), that showed a remarkable reduction in the occurance of hypersensitivity reactions. The main aim of the study was to evaluate the severity and extent to which hypersensitivity reactions occur after the administration of IV iron isomaltoside 1000 in an Asian population. Multistage sampling was adopted for this study. The overall sample size was 864. The mean age of the participants was 55.29 ±18.44 years. The results depicted that 63 (7.29%) of the entire participants faced hypersensitivity reactions after IV administration. A total of 43 (68.25%) of participants who experienced hypersensitivity reactions showed clinical symptoms within one hour, 11(17.46%) showed reaction in 1-3 hours and 9 (14.29%) showed in > 3 Hours.

Hydralazine is a direct-acting vasodilator and has a short biological half-life (2-4 hours) due to significant first-pass metabolism with poor oral bioavailability. The aim of the current research is to reduce the frequency of dosing and enhance bioavailability to improve patient compliance by developing and systematically evaluating the sustained release of Floating alginate microbeads of Hydralazine hydrochloride. Using sodium alginate as the hydrophilic carrier in combination with different viscosity grades of HPMC such as HPMC K4M, HPMC K15M and HPMC K100M as drug release modifiers for the preparation of floating alginate microbeads of Hydralazine Hydrochloride by ionotropic gelation and cross-linking technique. Prepared beads were evaluated for percentage yield, particle size, micromeritic properties, drug entrapment efficiency, drug loading capacity, swelling ratio, in-vitro buoyancy studies, in-vitro release (in acidic buffer pH 1.2) and in-vitro release kinetic study. No significant drug-polymer interactions were observed from FT-IR studies. In fixed concentration of sodium alginate and calcium chloride and increases in the coating polymer concentration results increases in diameter of microbeads and also decrease the swelling ratio of beads. With the increase in coating polymer ratio, drug entrapment efficiency has been improved. All the formulations (F1 to F9) floated immediately or with a very short lag time and remained floating up to 12 hours. From the result of in-vitro dissolution studies reveals that the formulation F9 gave sustained release pattern of drug upto 12 hours (99.75%) and exhibited zero order kinetic followed by non-fickian diffusion transport of mechanism. Hence the formulated HPMC K100M coated sodium alginate beads can be used as an alternative and cheaper carrier for the oral controlled delivery of Hydralazine hydrochloride, especially for the treatment of congestive heart failure.
Anaphylaxis: Life-Threatening Allergic Reaction
Authors: Hussain MD Sadique , Mohit Mr.
Published: September 2022

Anaphylaxis is an extreme allergic response that occurs quickly and even sometimes ends up killing. The episodes of anaphylaxis range from moderate ones and resolve spontaneously to fatal ones within minutes. The actual worldwide magnitude of anaphylaxis is unknown as multiple episodes do not exist in the population and several regions have not yet evolved reliable systems to track extreme allergic events. Global rates of all anaphylaxis attributable primarily to drugs and food-based anaphylaxis can be convincingly improved. Idiopathic anaphylaxis applies to unexplained anaphylaxis, which entails a death possibility, whether by shock or from upper or lower airway blockages. It is increasingly important to consider causes, stimuli, and patient-specific risk factors for serious or lethal anaphylaxis. Professionals in the health industry must be able to detect anaphylactic symptoms, handle the incident quickly and properly, and make decisions on prevention. The awareness of gaps in our knowledge and diagnosis of anaphylaxis will aid in the detection of promising objectives for potential care and prevention. Anaphylactic patients and their families and caregivers' knowledge help avoid and rapidly recognize and manage anaphylactic episodes. The emphasis of this paper is on signs and symptoms, disease pathogenesis, causes of risk, medication, management, education of anaphylaxis, and, also focuses on the Idiopathic anaphylaxis.
