Postrenal Transplant Disseminated Cryptococcosis Presenting as a Syndrome of Inappropriate Antidiuretic Hormone Secretion - A Case Report
Authors: Suresh Sandhya , Konnur Abhijit , Gang Sishir
Published: October 2022

Cryptococcosis is the most common invasive fungal infection to involve the central nervous system in the posttransplant period. Cryptococcal meningitis, which constitutes disseminated cryptococcosis, can present with nonspecific signs and symptoms leading to a diagnostic challenge. There are case reports of cryptococcal meningitis presenting as a syndrome of inappropriate antidiuretic hormone secretion (SIADH). A 54-year-old male with autosomal dominant polycystic kidney disease was a live-related renal allograft recipient 1 year back and presented with complaints of generalized weakness and imbalance while walking. His serum sodium on admission was 117 mEq/L and investigations were suggestive of SIADH. He was given hypertonic saline and fluid restriction. However, he had a recurrence of symptomatic hyponatremia. He was evaluated for the cause of SIADH. Chest X-ray and computed tomography of the thorax revealed patchy consolidation. In view of persistent giddiness and imbalance, lumbar puncture was done and cerebrospinal fluid (CSF) analysis showed hypoglycorrhachia with elevated protein and cell counts. CSF cryptococcal antigen test was positive. He was thus diagnosed with disseminated cryptococcosis with meningitis and pulmonary involvement. He received amphotericin B deoxycholate for 4 weeks, followed by fluconazole. He improved symptomatically and serum sodium normalized thereafter. This is the first case of disseminated cryptococcosis presenting with SIADH in the postrenal transplant period with one prior case being reported after a liver transplant. This highlights the variable presentations of cryptococcosis and the need to evaluate the primary cause in posttransplant patients presenting with hyponatremia.

Background:

Being happy in life is very essential to be healthy, which is important for nursing students to grow and adapt well in their professional life.

Aim:

The aim of this study is to assess the level of happiness and identify the determinants of happiness among nursing students.

Materials and Methods:

Three hundred and forty-two undergraduate nursing students College of Nursing, All India Institutes of Medicals Sciences, New Delhi, India, enrolled in the study by convenience sampling. Data were collected through demographic information sheets and oxford happiness questionnaires. Frequencies, percentages, mean, standard deviation, Chi-square test, and multiple linear regression were used to analyze the data.

Results:

The mean happiness score of nursing students was 3.96 ± 0.59 on a scale of 6. The percentage distribution showed that 43.2% of the students responded “not particularly happy,” and 42.1% were “rather happy.” The current year of study, the number of close friends, stress experienced in the past 6 months, and engagement in physical activities contributed 53% of the variance in the happiness score of nursing students (P < 0.001). Further, monthly family income (P = 0.018) and choice of course (P = 0.003) had a significant association with their happiness score.

Conclusion:

Nursing students had a moderate level of happiness. The study suggests that there is a need to develop strategies to enhance happiness among nursing students in alignment with the identified factors. Educators need to develop a holistic curriculum giving equal importance to academic competencies and personal flourishment.

Published: October 2022

The alarming growth in online gaming activities in recent years calls for an understanding of the determinants of gaming behaviors among adolescents and young adults. A systematic review was conducted to collate and review all the research studies concerning the understanding of the gaming motives. Relevant published articles were identified through the electronic search from PubMed, Medline, PsycInfo, Sciencedirect, and APA databases. The review identified four major topics of gaming motives, namely gaming behavior, gaming usage pattern, gaming demographics, and associated psychopathology. The review highlighted the role of motives in gaming use and psychopathology. The age of the player was associated with the expression of these motives. Further insights were drawn into the role of motive in the recreational and problematic use of gaming. The study findings emphasize the need to develop adequate interventions to prevent the occurrence of psychological impairments that would result from potentially problematic video gaming.

Published: October 2022

Background:

Cognitive impairment and alexithymia are commonly associated with schizophrenia and alcohol use disorder independently. Both can lead to poor prognosis and recovery. In patients with dual diagnosis, this association can be more prevalent and severe.

Materials and Methods:

A total of 75 participants were grouped into two (35 each): Group A, a Schizophrenia group and Group B with comorbid alcohol use. Sociodemographic factors, clinical profile, cognitive functions, and alexithymia were compared between the two groups using semi-structured pro forma, Positive and Negative Syndrome Scale, Alcohol Use Disorders Identification Test (AUDIT), Montreal Cognitive Assessment (MoCA) Scale, Toronto Alexithymia Scale (TAS-20) (subcategorized into three subscales (1) “Difficulty describing feelings” (DDF), (2) “Difficulty identifying feeling” (DIF), and (3) “Externally-Oriented Thinking” and Brief Psychiatric Rating Scale. Statistical analysis was performed using the Chi-square tests and t-tests as applicable. P < 0.05 was considered statistically significant.

Results:

The mean age of the participants was 33.61 (standard deviation [SD]-8.11), mean duration of schizophrenia was 70.8 months (SD-47.5) and mean duration of alcohol consumption was 9.10 years (SD-7.7). MoCA score was significantly lower (mean-21.80, SD-2.98) and TAS total score was significantly higher in Group B (Mean-67.31, SD-8.10). DDF (Mean-19.28, SD-4.02) and DIF scores (Mean-22.86, SD-4.66) were significantly higher in alcohol group compared to nonalcohol group. Furthermore, MoCA score was significantly impaired and TAS total, DDF and DIF scores were significantly higher in participants with AUDIT score >8 (P < 0.05). Lower score on MoCA correlated with the higher score of alexithymia.

Conclusion:

Cognitive dysfunction and alexithymia were significantly more in patients of schizophrenia with comorbid alcohol use and positively correlated with the severity of alcohol use disorder.

У статті зроблено акцент на особливостях розвитку творчих здібностей у здобувачів освіти під час проведення занять з української мови, літератури, української мови (за професійним спрямуванням) та за допомогою позааудиторних заходів;  визначено актуальні засоби реалізації даної проблеми для вирішення основних освітніх завдань, зокрема, нові підходи до гурткової роботи в сучасних навчальних закладах та форми взаємодії з учасниками навчально-виховного процесу з метою розвитку та формування креативної компетентності у майбутніх фахівців. Визначаються також основні складники роботи зі здібною молоддю, пропонуються шляхи подолання комунікативної нестабільності через залучення здобувачів освіти до гурткової роботи та творчих домашніх завдань і проєктів. Зосереджено увагу на тих змінах, що повинні бути внесені до змісту навчально-виховного процесу для удосконалення роботи предметних гуртків у закладах вищої та фахової передвищої освіти. Врахована креативна роль викладача у виборі форм та методів роботи з творчими групами та проєктами. Наведено приклади масових заходів, позааудиторних форм роботи, творчих вправ та завдань, які практично були використані під час навчання та в ході виховної роботи. Використано авторський матеріал, творчі надбання викладача та його вихованців. Розкрито системну роботу творчих майстерень, взаємодії викладача та здобувачів освіти, особливості моделювання проблемних завдань, професійних виробничих ситуацій. Саме у цьому є перспектива вивчення проблеми розвитку креативності молоді та професійної гнучкості. Немає дітей нездібних, бракує учителів, які б побачили і розкрили їх талант. А для цього повинно бути бажання педагога і можливості, вибір форм, методів, засобів для виховання та навчання. Доведено, що необхідна навчальна співпраця, в процесі якої відбувається розвиток творчого мислення, яке дає змогу молодим людям бачити те, чого ще немає, але що може бути створене ними (для пошуку невідомого, нового, загадкового, незвичайного). Творче мислення, творчі здібності формуються через творчу активність.

— Volatile organic compounds (VOCs) are among the most common pollutants released into the air in the petrochemical and chemical industries. The article deals with removing VOCs while producing plastic granules containing approx. 80% polypropylene and polyethene, together with other additives. In this sector, the simplifying factor is that it deals with only one volatile pollutant, total organic carbon TOC, regardless of the specific materials from which the VOC emission originates. The permissible pollution level indicates a TOC emission limit of 50 mg ∙ m-3 for this production. During operation, emissions are extracted from the machinery to a stationary source. It is a fabric filter where the air is cleaned through a layer of diatomaceous earth. To determine if the above limit is not exceeded, measurements showed that the TOC limits are significantly higher (82.9 mg m-3 ). Therefore, tests were carried out using a mixture of activated carbon and diatomaceous earth. The results showed that activated carbon significantly reduced TOC concentrations to 8.4 mg m-3 . Keywords— Activated carbon, diatomaceous earth, polymers, stationary source, total organic carbon, TOC, volatile organic compounds, VOC.

Published: October 2022

The energy demand is on the rise in all over the world; at the same time, the wastage of energy is also increasing. Footstep Power Generator “FsPG” is developed to help finding ways to utilize human force in most usable ways by generating a power that depends on footsteps. In this paper, we built a noise free power generator that depends on human foot force applied on the” piezoelectric” sensors which are placed bellow the platform. The force is converted to electrical energy. The produced electrical power is then stored in 12V rechargeable battery which helps the users to charge specific loads with a USB cable that is attached to the system. The system is successfully tested to generate a maximum voltage of 23.6 V across the cells when a maximum average weight of 75 Kg is applied on the system plates.

Published: October 2022

The use of mixed image sources requires digital preprocessing to separate them, for making easier their storage and improve their quality. The ICALAB for Image Processing method is one of the solutions proposed for the blind efficient separation of signals without prior knowledge of the source images. Nevertheless, to choose the appropriate algorithm with the most efficient separation index, several tests are carried out on a certain number of algorithms, with off-line processing of image samples bases, by means of software tools which are generally installed on a computer, such as ICALAB, TIPICA, GIFT, NMFLAB, model identification UBSS, ... Thus, in order to perform the image separation processing in real time, this study aims to develop a rapid prototyping embedded system for implementing the blind source separation concept. It mainly provides a promising approach for implementing twelve efficient blind image separation algorithms on the ZYBO Z7 FPGA board, using Xilinx System Generator (XSG) for Real Time Hardware Co-simulation. As an application example, this study deals with the blind separation of two e-frames mixture, and then provides the adequate algorithm, basing on the calculation of the Performance Index (PI), and the separated images results.

Published: October 2022

Cardiovascular diseases (CVD) are among those with the highest mortality rates, and various wearable devices for continuous monitoring are emerging as a complement to medical procedures. Blood pressure (BP) monitoring in wearable devices, in order to be continuous, must be performed noninvasively, thus involving photoplethysmography (PPG), a technology that has been widely studied in recent years as a non-invasive solution for BP estimation. However, continuous data acquisition in a wearable system is still a challenge, one of the reasons being the noise caused by movement, the correct use of the PPG signal, and the estimation method to be used. This paper reviews the advances in blood pressure estimation based on photoplethysmography, focusing on the analysis of the preprocessing (ICA, FIR, adaptive filters) of the signals. Among the filters reviewed, the most suitable for dealing with Motion Artifacts (MA) of a wearable system are the adaptive filters, because conventional filters are limited to work only in the band for which they are designed, which does not always cover the spectrum of the MA. A review of the estimation methods is also carried out, among them machine learning stands out because it shows greater growth due to the new proposals that use more signals and obtain better results in terms of accuracy. The objective is to know and analyze the appropriate preprocessing filters and estimation methods from the perspective of wearable systems using PPG sensors affected by AM. Keywords— Blood Pressure Estimation, PAT, PTT, Machine Learning, Photoplethysmography, adaptive filtering.

Authors:   Department of Digital Technology, Faculty of Science and Technology, Phuket Rajabhat University, PHUKET 83000, Thailand, Pornphol Putsadee , Saejueng Charoensak
Published: October 2022

The rubber tree is considered one of the most important economic crops in Thailand generating a large amount of income for the country. The problem of rubber prices that have been continuously declining since 2012 is a critical issue that requires an appropriate solution. Consequently, a study to understand the demand and supply model of rubber along with data collection and visualization of rubber planting in Thailand are highly essential. A finding from this paper presents that there is an excessive supply of rubber over its demands. Accordingly, one of the proposed solutions to solve the rubber price problems is that the Thai government should have strict control over rubber planting areas in Thailand as the rules specified in agro-economic zones. Another proposed solution is that the Thai government may include some provinces in the northeast of Thailand in agro-economic zones as these areas also generate a high volume of rubber. Keywords—rubber price, data visualization, web scraping, system dynamics, causal loop diagram, agro-economic zone.
Countermeasure to Structured Query Language Injection Attack for Web Applications using Hybrid Logistic Regression Technique
Authors: Shagari Shehu Magawata , Gabi Danlami , Dankolo Nasiru Muhammad , Gana Noah Ndakotsu
Published: October 2022

The new generation of security threats has been promoted by real-time applications, where several users develop new ways to communicate on the internet via web applications. Structured Query Language injection Attacks (SQLiAs) is one of the major threats to web application security. Here, unauthorised users usually gain access to the database via web applications. Despite the giant strides made in the detection and prevention of SQLiAs by several researchers, an ideal approach is still far from over as most existing techniques still require improvement, especially in the area of addressing the weak characterisation of input vectors which often leads to low prediction accuracy. To deal with this concern, this paper put forward a hybrid optimised Logistic Regression (LR) model with Improved Term Frequency Inverse Document-Frequency (ITFIDF-LR). To show the effectiveness of the proposed approach, attack datasets is used and evaluated using selected performance metrics, i.e., accuracy, recall, specificity and False Positive Rate. The experimental results via simulation when compared with the benchmarked techniques, achieved performance record of 0.99781 for accuracy, recall and F1-score as well as 0.99782, 0.99409 and 0.00591 for precision, specificity and False Positive Rate (FPR) respectively. This is an indication that the proposed approach is efficient and when deployed is capable of detecting SQLiA on web applications.

Excessive physical and mental activity will lead to consequences in the form of workload. The workload caused by the demands of the job if it is lower than the ability of the worker is likely to cause boredom, on the contrary if the demands of the job are higher than the ability of the worker it will cause fatigue at work. CV. SBRC is a company engaged in the manufacturing industry, namely the production of gloves. Production activities at CV. SBRC is still done manually or by manpower. This study aims to analyze the physical and mental workload of workers on CV. SBRC. The methods used are Job Strain Index and NASA-TLX. Based on the results of this study, the results of the physical workload analysis showed that 9 out of 10 production processes were included in the hazardous category. While the results of the analysis of the mental workload of workers are in the medium category. To overcome activities that fall into the dangerous category, a proposed improvement plan is made for these work activities.

Aktivitas fisik dan mental yang dilakukan manusia secara berlebihan akan menimbulkan konsekuensi berupa beban kerja. Beban kerja yang disebabkan oleh tuntutan pekerjaan jika lebih rendah dari kemampaun pekerja kemungkinan akan menimbulkan kebosanan, sebaliknya jika tuntutan pekerjaan lebih tinggi dari kemampuan pekerja maka akan menimbulkan kelelahan dalam bekerja. CV. SBRC adalah perusahaan yang bergerak di bidang industri manufaktur, yakni produksi sarung tangan. Aktivitas produksi pada CV. SBRC masih dilakukan dengan cara manual atau tenaga manusia. Penelitian ini bertujuan untuk menganalisis beban kerja fisik dan mental pekerja pada CV. SBRC. Metode yang digunakan adalah Job Strain Index dan NASA-TLX. Berdasarkan hasil penelitian ini didapatkan hasil analisis beban kerja fisik bahwa 9 dari 10 proses produksi termasuk dalam kategori berbahaya. Sedangkan hasil analisis beban kerja mental pekerja berada dalam kategori sedang.

One of the main factors to improve product quality is to carry out quality control. The purpose of this research is to reduce or suppress the number of defective tile products produced by controlling quality. The analytical method used in this research is Statistical Process Control (SPC) by calculating the percentage of damage to the product, CL, UCL, and LCL. The results of this study found that quality control in Super Soka Masinal Tile UKM was not controlled, this can be seen based on the calculation that there are 4 points outside the control limit so that the number of rejects exceeds the maximum allowable limit. And based on the Pareto diagram, it is known that the crack defect is the highest defect with a percentage of 44%. Therefore, it is necessary to propose improvements to crack defects using a fishbone diagram.

Salah satu faktor utama untuk meningkatkan kualitas produk adalah dengan melakukan pengendalian kualitas. Tujuan pada penelitian ini adalah untuk mengurangi ataupun menekan jumlah pada produk cacat genteng yang dihasilkan dengan cara melakukan pengendaian kualitas. Metode analisis yang digunakan dalam penelitian ini adalah Statistical Process Control (SPC) dengan menghitung persentase kerusakan pada produk, CL, UCL, dan LCL. Hasil penelitian ini ditemukan bahwa pengendalian kualitas di UKM Genteng Super Soka Masinal tidak terkendali, ini dapat dilihat berdasarkan perhitungan terdapat 4 titik berada di luar batas kendali sehingga jumlah reject yang ada melebihi batas maksimal yang diperbolehkan. Dan berdasarkan diagram pareto, diketahui bahwa cacat retak merupakan cacat yang tertinggi dengan persentase 44%. Oleh karena itu perlu dilakukannya usulan perbaikan pada cacat retak dengan menggunakan fishbone diagram.

Published: October 2022

OBJETIVO: Describir los procesos neurofisiológicos que intervienen en la neurociencia social y su influencia para el desencadenamiento de la ansiedad en la etapa de la adolescencia. METODOLOGÍA: construcción teórica a partir de revisión bibliográfica y reflexiones. RESULTADOS: la neurociencia social desde la biología (inmune, endocrino, neuronal) se encarga de estudiar la conducta dentro de la sociedad, centrándose en la etapa de adolescencia donde surgen cambios cognitivos, físicos, sociales y emocionales resultado del funcionamiento molecular, celular, químico y biológico del sistema nervioso. CONCLUSIÓN: en la adolescencia las funciones ejecutivas reflejan el grado de madurez cognitiva, por tanto, estructuras como la corteza prefrontal vincula emociones, autocontrol y toma de decisiones, pero en ciertos casos los adolescentes tienen elementos frágiles como la sensibilidad a comentarios, críticas y exigencias sociales que influyen en la salud mental siendo factores determinantes para desencadenar depresión, adicciones y la ansiedad.

Published: October 2022

OBJETIVO: describir la neurofisiopatología del estrés postraumático METODO: construcción teórica con base a revisión bibliográfica y reflexiones RESULTADOS: el trastorno de estrés postraumático (TEPT) es una enfermedad mental y se manifiesta con tensión o estado de alerta. Puede desarrollarse luego de la exposición a un estresor el cual infiere en el comportamiento generando principalmente una respuesta defensiva, este es un punto de partida para la comprensión de un comportamiento.  Los factores de vulnerabilidad son, los traumas en la infancia, experiencias violentas, accidentes de tránsito, fenómenos naturales, afecciones físicas y actualmente la pandemia por COVID-19. El trauma no solo provoca efectos mentales, sino que también provoca una especie de reset o recalibración del sistema nervioso. CONCLUSIÓN: un acontecimiento traumático hace que el cerebro cambie, produciendo una activación del sistema de alarma, se genera una reducción del volumen del hipocampo y en el eje Hipotálamo-Hipofisario-Adrenal también se produce una alteración en su funcionamiento; la interacción recíproca entre estos tres órganos genera las reacciones propias de la respuesta de estrés.

The name of the institution is one of its main features by which the institution is primarily identified in the field of its activities and how it differs from other entities. At the same time, given the diversity of activities in which institutions are engaged, regardless of whether it is in principle public service or non-profit activity, institutions also participate in a kind of market competition in which their name is promoted or advertised. Therefore, due attention must be paid to the protection of the name of the institution from unfair actions of other entities, especially in the existence of clear and consistent legal regulations, which will provide holders with quick and effective protection against possible violations of their registered rights.

Authors: SIMSEK Serap , UNAY Aydin
Published: October 2022

The mean performance and combining abilities of cross combinations derived from a complete diallel mating and their parents were evaluated under waterlogging conditions. Analysis of variance for combining abilities indicated significant GCA (general combining ability) and SCA (specific combining ability) for single spike yield, SPAD (soil plant analysis development) and leaf area; GCA for NDVI (normalised differences vegetation index) and SCA for Fe and Mn contents in roots and membrane thermal stability. The parents Stendal, Beşköprü and Pamukova 97 were the best combiners in terms of waterlogging tolerance, while Beşköprü × Pamukova 97, Pamukova 97 × Beşköprü, Stendal × Pamukova 97, Stendal × Beşköprü and Beşköprü × Hanlı were identified as the best cross combinations, with high positive specific combining ability effects for most waterlogging related characters.

Myocarditis has been reported as a presentation of COVID 19 in children. Cardiac tissue inflammation could enhance the automaticity of the cells and develop different types of arrhythmias. Atrial para-systole is a very rare type of arrhythmia mostly observed in patients with right isomerism or post-cardiac transplantation. Whereas, we report atrial para-systole arrhythmia in an infant with normal cardiac and visceral anatomy which is affected by COVID-19 and presented with tachycardia and heart failure.
