Authors: Machado Mariane Gomes , Machado Thais Helena , Caramelli Paulo , Gonçalves Tosatti Jessica Abdo , da Silva Carvalho Sirley Alves , de Resende Luciana Macedo
Published: July 2024

Background:

The assumption that hearing rehabilitation could improve quality of life and reduce dementia risk in people with hearing loss is a subject that needs further studies, especially clinical trials. It is necessary to determine the effects of hearing aid use, as part of hearing rehabilitation, among people diagnosed with dementia.

Objective:

To systematically review the literature to evaluate the effects of hearing aid use on cognition and quality of life of people with dementia.

Methods:

Protocol for this systematic review was registered (CRD42023387187). The Cochrane Central Register of Controlled Trials, Embase, MEDLINE, Scopus, CINAHL, and Web of Science databases, as well as grey literature, including Google Scholar and ResearchGate, were systematically searched for clinical trials using MeSH terms. The PICOS principle was used to develop the inclusion criteria: population (P): adults and older adults, individuals diagnosed with dementia and hearing loss; intervention (I): rehabilitation with hearing aids; control (C): not using a hearing aid; outcome (O): cognitive and/or quality of life assessment using validated tests; study design (S): clinical trial.

Results:

The initial search yielded 576 studies, five of which met the inclusion criteria for qualitative analyses. Two of the included studies were randomized clinical trials, and three were crossover clinical trials, demonstrating the lack of studies on the subject. Four studies included participants with Alzheimer’s disease. Quality of life was found to improve with the use of hearing aids, and hearing rehabilitation was not shown to affect cognitive outcomes.

Conclusions:

Hearing aid use appears to have a positive impact on quality of life.
Protective Proteolysis in Huntington’s Disease: Unraveling the Role of Post-Translational Myristoylation of Huntingtin in Autophagy
Authors: Alshehabi Yasmeen , Martin Dale D.O.
Published: July 2024

Huntington’s disease (HD) is a devastating neurodegenerative disorder characterized by impaired motor function and cognitive decline, ultimately leading to death. HD is caused by a polyglutamine expansion in the N-terminal region of the huntingtin (HTT) protein, which is linked to decreased HTT turnover, increased HTT proteolysis, increased HTT aggregation, and subsequent neuronal death. In this review, we explore the mechanism of the protective effect of blocking HTT proteolysis at D586, which has been shown to rescue the HD phenotype in HD mouse models. Until recently, the mechanism remained unclear. Herein, we discuss how blocking HTT proteolysis at D586 promotes HTT turnover by correcting autophagy, and making HTT a better autophagy substrate, through post-translational myristoylation of HTT at G553.

Published: July 2024

BACKGROUND: Conducting mild traumatic brain injury (mTBI) longitudinal studies across multiple sites is a challenging endeavor which has been made more challenging because of COVID-19. OBJECTIVE: This article briefly describes several concerns that need to be addressed during the conduct of research to account for COVID-19’s impact. METHODS: The recent actions and steps taken by the Long-term Impact of Military-relevant Brain Injury Consortium (LIMBIC)-Chronic Effects of Neurotrauma Consortium (CENC) researchers are reviewed. RESULTS: COVID-19’s effects on the conduct of LIMBIC-CENC for the short-term and long-term were considered to ensure the study continued safely for participants and researchers. COVID-19 may have long-lasting health and especially neurological effects which may confound the quantitative and qualitative measures of this any comparable longitudinal studies. CONCLUSION: The recognition, understanding, and preparation of COVID-19’s impact on a longitudinal military and veteran mTBI population is crucial to successfully conducting LIMBIC-CENC and similar neurological research studies. Developing a plan based on the best available information while remaining agile as new information about COVID-19 emerge, is essential. Research presented in this special issue underscores the complexity of studying long-term effects of mTBI, in a population exposed to and symptomatic from COVID-19.

Authors: Barnett Nathan , Ljubic Milica , Chung Joyce , Capizzi Allison
Published: July 2024

BACKGROUND: U.S. Special Operations Forces (SOF) are at increased risk of multiple mild traumatic brain injury (mmTBI). Testosterone was prescribed for several participants in a VA program designed to address sequelae of mmTBI for SOF. OBJECTIVE: To determine testosterone prevalence in the Palo Alto VA Intensive Evaluation and Treatment Program (IETP) and observe for association between testosterone and neurobehavioral outcomes. METHODS: A retrospective cohort study included patients in the Palo Alto VA IETP. Sociodemographic data, testosterone blood levels, and neurobehavioral outcomes were collected from medical records. RESULTS: 55 IETP participants were included: six were testosterone users; the rest were classified as non-users. Testosterone use in this population is 11%, higher than reported national averages in the U.S. Of the 6 testosterone users, 2 (33%) had a formal diagnosis of hypogonadism prior to initiation of testosterone. Neurobehavioral outcome scores between testosterone users and non-users failed to show statistically significant differences, except for the PROMIS pain score, which was higher in the testosterone user population. CONCLUSION: The current study did not find an association between mmTBI, testosterone use, or testosterone level and neurobehavioral outcomes. This study highlights a need to further examine the relationship between hypogonadism, mmTBI, SOF culture around testosterone, and the effects of testosterone use in this population.
Telerehabilitation – historical perspectives and conceptual framework in reference to neurological disorders: A narrative review
Authors: Olowoyo Paul , Dhamija Rajinder K. , Owolabi Mayowa O.
Published: July 2024

BACKGROUND: Telerehabilitation as a new subdiscipline of telehealth is the application of information technology to support and deliver rehabilitation services via two-way or multipoint interactive online telecommunication technology. This enables the therapist to optimize the timing, intensity, and duration of therapy which is often not possible within the constraints of face-to-face treatment protocols in current health systems. OBJECTIVE: To review the historical perspective and conceptual framework of telerehabilitation in neurological disorders. METHODS: A narrative review of the literature was performed for the historical perspective and a systematic review of the conceptual framework was performed using the PRISMA guidelines on chronic neurological disorders; multiple sclerosis, spinal cord injury, stroke, Parkinson’s disease, cognitive impairment, and headaches. The search included articles from the past 20 years (2004 to 2024). RESULTS: Telerehabilitation dates back to the 1960s and early 1970s. Documented effective interventions were mostly on therapies for speech disorders. The conceptual framework consisted of three major components of telerehabilitation programmes including development, implementation, and evaluation. The COVID-19 pandemic suddenly made telerehabilitation come to the limelight because physical distancing became necessary. Out of the 110,000 articles downloaded, 43 met the inclusion criteria for review on the conceptual framework of telerehabilitation in relation to neurological disorders. The articles discussed multiple sclerosis (2), spinal cord disorders (1), stroke (17), Parkinson’s disease (15), headaches (3), and cognitive disorders (5). All articles reviewed assessed the effectiveness of telemedicine except for the articles on multiple sclerosis and spinal cord disorders which examined the interphase between the technology and the end users. CONCLUSION: The future of telerehabilitation looks promising with the subsequent integration of innovative tools and applications. This will require the adaption of technology, continuous capacity building, education, and training of healthcare professionals to ensure that they are adequately equipped with the necessary skills to provide quality virtual reality rehabilitation care.

Authors: Sonawane Sunil , Gulwani Reshma , Sharma Pooja
Published: July 2024

Malicious traffic segregation and attack detection caused major financial loss and became one of the most serious security hazards. Moreover, cyber security attack is the major issue, which impacts network security. The network attack methods are constantly being upgraded by the technology development and it remains a major issue for detection and protection against network attacks. For this, it is required to present an effective strategy for detecting and maintaining network security. The work provides timely and accurate congestion attack detection and identification. In the Internet of Things (IoT) cloud system malicious traffic segregation and attack detection based on a hybrid optimization-enabled deep learning (DL) network is developed in this research. At first, the input log files are gathered from the simulation of IoT sensors and the superior route is selected by the proposed Fractional Hunger Jellyfish Search Optimization (FHGJO) algorithm. The FHGJO is the integration of Hunger Game Jelly Fish Optimization (HGJO) and Fractional Calculus (FC). Furthermore, the HGJO is the combination of Hunger Game Search Optimization (HGS) with Jellyfish Optimization (JSO). Then, the segregation is done based on the fitness measures and for preprocessing; the input data is fed using quantile normalization. The feature selection process is employed using the weighted Euclidian distance (WED). With the SpinalNet, the malicious segregation is categorized as malicious and non-malicious and the proposed FHJGO is used to tune the SpinalNet. Furthermore, the proposed FHGJO-trained Deep Quantum Neural Network (DQNN) is utilized to detect the attack and classifies it into a Denial-of-Service (DOS) attack, Distributed Denial of Service (DDoS) attack, and buffer overflow attack. Moreover, the proposed model is evaluated using the NSL-KDD dataset and BoT-IoT dataset. The proposed method ensures network security with 0.931 accuracy, 0.923 sensitivity, and 0.936 specificity.

Authors: Pélissier Carole , Varano Mariasole , Moulin Martine , Carcasset Pierre , Fontana Luc
Published: July 2024

BACKGROUND: In a context of reorganization of the activity, of increase of the psychological, emotional and physical constraints of the nursing staff induced by the first wave of the COVID-19 pandemic, an increase of the anxiety disorders could occur. OBJECTIVE: This study aims to assess the prevalence of anxiety disorders in healthcare workers (HCWs) by wards and to investigate medical, personal, and occupational factors associated with anxiety disorder. METHODS: In France, in May 2020, a monocentric observational cross-sectional study was proposed to 285 HCWs of the University Hospital of Saint Etienne, working in 3 types of randomly selected care wards. Information was collected using an anonymous self-questionnaire offered to eligible HCWs. Validated questionnaires were used to assess anxiety (Hospital anxiety and Depression Scale) and burnout (Maslach Burnout Inventory). RESULTS: Of the 164 HCWs who participated in the study (57% participation rate), 69 (42%) caregivers had anxious symptomatology. The prevalence of anxiety disorders did not differ significantly by type of wards. Anxiety disorders are significantly associated with occupational factors (increased COVID-19 stress level, increased emotional load, increased mental load, high work/life stress during confinement, emotional exhaustion and loss of empathy), with medical factors (medical history of anxiety disorders, psychotropic treatment and impaired sleep quality) and personal factors (concern about working conditions and/or media reports). CONCLUSIONS: Preventive actions focusing on organizational factors could be carried out to reduce the emotional and mental load, the level of stress and the burnout of HCWs.

Haemostatic Proteins as Markers of Disease Progression and Prognosis in Breast Cancer
Authors: Izuegbuna Ogochukwu
Published: July 2024

BACKGROUND: Breast cancer is a leading cause of cancer death in women worldwide. One of the major causes of death from breast cancer is metastatic disease which results from the malignant cells invading and migrating through blood vessels to distant sites.

TEXT: Several studies have shown that metastasis is facilitated by haemostatic proteins. Breast cancer is characterized by haemostatic imbalance which is tilted more to a procoagulant state with resultant thrombotic complications. These elements that are involved in thrombosis also play key roles in different aspects of breast cancer growth including cancer proliferation and progression, cancer survival, angiogenesis and metastasis. Some of these elements include platelets, endothelial cells, coagulation factors and fibrinolytic proteins. There is a close relationship between cancer and many of the haemostatic elements. They are usually increased in metastatic breast cancer, and have found use as predictive and prognostic markers. Some have been validated in breast cancer. Due to their seemingly active roles in breast cancer progression, some of the haemostatic proteins are being developed as diagnostic tools in the management of breast cancer. They are equally being seen as potential targets for the development of novel therapies in breast cancer or repurposing drugs in current use for the same gain.

CONCLUSION: This review highlights the role haemostatic proteins play in breast cancer progression, and their diagnostic and therapeutic relevance.

"The economy of the world has been seriously affected by increased demands for energy and food. The price of gasoline gradually has gone up while more children have died in poor countries before the age of five from malnutrition. Ways must be found to solve these problems for the growing world population. Cellulose is the major organic material in the world with an annual production of 10^11 tons/year 1n the forms of cotton, lumber, pulp wood, etc., which could be converted Into energy and food. Numerous conventional processes have been proposed to obtain other chemicals from cellulosics such as gasification at high temperature to form synthesis gas, liquefaction under high pressure to produce oil, and pyrolysis to charcoal, gas and oil. Several unconventional processes have been developed for the biological conversion of cellulose to useful nutritional products by the hydrolysis of cellulose to glucose. Glucose can be used as food by man and animals, converted microbially into single-cell protein, or fermented to ethanol for use as a fuel."--Introduction.
Limnological characteristics of the main channel and nearshore areas of Lake of the Ozarks, Missouri
Authors:   , Mitzelfelt Jeffrey D.
Published: July 2024

Lake of the Ozarks is a large main stream reservoir located in the Ozark Plateau of west central Missouri. The reservoir attracts an extensive tourist population and, thus, a great deal of recreational development surrounds the lake. The main purpose of this study was to determine if this development affects the water quality of the nearshore waters as measured by trophic status and fecal coliform concentrations. Twenty-nine coves representing a range of development from no development to intensive development and located in the Grandglaize-Turkey Bend region of the lake were selected for study. The results of the study revealed that nearshore waters had more eutrophic characteristics as development of the adjacent watershed increased. Although differences in trophic status were small, they were consistent. Similar comparisions of fecal coliform data showed large increases in concentrations (up to 50 times) with increases in development. Fecal coliform concentrations were also found to be related to population of the lake area as measured indirectly by road use data. Fecal coliform concentrations were observed to increase dramatically during weekends and holidays when the tourist population was also higher. This study has shown that current sewage treatment methods are not totally effective in the removal of nutrients and pathogenic organisms. If current trends in increased development continue, alternative methods of sewage treatment must be implemented if further degradation of the nearshore waters is to be avoided. Additionally, collection of fecal coliform samples for purposes of water quality monitoring may need to be scheduled during weekends or holidays in order to protect the large number of people using the lake area during these periods.
Mass transfer under sonic fields
Authors:   , Sohn Ung Nak
Published: July 2024

"The field of mass transfer is one of great interest to chemical engineering. An understanding of this field is vital in the design of many types of chemical processing equipment, particularly in the areas of distillation, extraction, absorption, adsorption, and reactor analysis and design. Generally it is a main goal for engineers to get high mass transfer rates. Therefore much research on mass transfer was devoted to find a better way to get higher mass transfer rates, understanding the mechanism, and applying the results to industrial processes. Some of the factors which influence the mass transfer rate are enumerated: 1. The mass transfer area of the interphase 2. The driving force between phases 3. Hydrodynamic conditions at the interface between phases 4. Contact time of the two phases 5. Physical properties of the two phases The purpose of this investigation was to study the influence of sonic vibration on COg gas absorption into tap water. Naturally, each bubble has its own characteristic vibrational frequency which depends on its size and composition as well as the medium surrounding it (14). Therefore, if the driving sonic vibration is at the bubble's resonant frequency, the flow region in the immediate vicinity of the bubble's surface is affected so that the diffusion resistance is reduced, the bubble surface area is increased, and the contact time is increased (14). Firstly, the study was to determine if the mass transfer rate is increased with the sonic vibration over that without sonic vibration. Therefore the absorption percentage with sonic vibration was compared with that without sonic vibration. Secondly, the absorption rate as a function of one of the variables stated below was measured in order to find the maximum mass transfer conditions. The variables examined are: 1. Median frequency 2. Sweep rates of the sonic vibration 3. Sweep ranges of the sonic vibration 4. Column height. Thirdly, the absorption rate as a function of the sonic power to the system was measured to understand the power requirement for the gas absorption."--Introduction

Feedforward control of a distillation column
Authors:   , Peng Yi-Man
Published: July 2024

"The primary objective of any distillation system is to deliver products of consistent quality. Since the recovery time of industrial sized columns is generally very long, distillation columns controlled only by feedback can produce large amount of poor quality material before control action is initiated. Feedforward control helps to overcome this disadvantage. Because corrective action is taken before the error occurs, it is hoped that no error will exist for propagation around the loop. The disadvantages of feedforward control (3) are: (A) The disturbance must be detected. If it can not be measured, feedforward control can not be used. (B) A model of how the disturbance and manipulated variables will affect the process must be known. This study discusses a potentially useful feedforward control scheme. In this case, the reflux flow rate is the manipulated variable and the feed composition is the disturbed variable as illustrated in Figure 1-3. Because the computer is not yet available for experimental use, a mathematical simulation of the distillation column is used. The simulation program developed by Mr. Jerome D. Cole (4) provides a detailed and relatively accurate model of the distillation column. In order to develop feedforward control, a linearly approximated transfer function is found for small deviations from a typical steady-state value. These transfer functions were determined using a program CSTRIP (5). This thesis presents a determination of the transfer functions to be used in the feedforward control system. It compares the results for dynamic and steady-state feedforward control algorithms for both a step disturbance and a sinusoidal disturbance. In addition, the effect of sampling times for a digital system is studied for the sinusoidal case."--Page 2.

Published: July 2024

"Introduction: Flows which are generated entirely by the action of bouyancy forces on fluids with density variations due to heating are referred to as natural or free-convection flows. Convection in a fluid saturated porous media is an important topic in heat transfer research because of its wide variety of applications: oil and gas production, steam stimulation of oil fields, coal gasification, oil shale retorting, process catalytic reactor applications, nuclear related problems, geothermal energy, porous insulation and drying processes. This study considers the transient natural convection heat transfer by air in an enclosed heat generating porous media. The porous media is a short circular cylinder. Figure (1.1) is a schematical representation of the situation. The project represents a simulation of stored grain in a bin. Grain in a storage bin is subject to natural convective heat and mass transfer, which is forced by changes in ambient temperature and internal heat generation from grain deterioration."--Page 1.
Development and evaluation of pattern recognition habitat models for the ruffed grouse, gray squirrel, and fox squirrel in Missouri
Authors:   , Laubhan Murray K.
Published: July 2024

Pattern recognition (PATREC) models are single-species models that use habitat characteristics to arrive at an estimation of population abundance. Currently, personnel of the Mark Twain National Forest in Missouri are using this type of model as a basis for making management decisions on 13 management emphasis species. Before the outputs of these models can be used with confidence, however, relational functions that support the models must be explored and quantified by research. The primary purpose of my study was to develop and evaluate PATREC models for the ruffed grouse (Bonasa umbellus), gray squirrel (Sciurus carolinensis), and fox squire! (Sciurus niger) in Missouri. I measured vegetative structure and population abundance of ruffed grouse and both squirrel species on 13 and 14 study areas, respectively, to identify habitat features associated with high and low densities of each species~ Six habitat parameters were determined to be related to ruffed grouse density. Areas with high spring densities(> 13.0/405 ha) had significantly (P < 0.01) greater amounts of disturbed forest habitats and lower amounts of upland sawtimber than areas with low densities. structural characteristics influencing the quality of disturbed cover included basal area, woody stem density, and canopy closure. Woody stem density was also an important habitat condition of the upland sawtimber cover type. The PATREC model developed with these 6 parameters correctly classified 100 percent of the study areas into either high o~ low density classes. Based upon model outputs, areas with low densities were deficient in either the percent occurrence or structural characteristics of the disturbed cover type indicating that management for ruffed grouse in Missouri should be directed toward providing more of this habitat type. Population estimates of squirrels concurred with 2 years of poor acorn mast production. During and immediately following poor mast years, it appears that both fox squirrels and gray squirrels use areas where timber is interspersed with crops and old fields. These areas may provide a source of supplemental food. In contrast, both species were negatively correlated with the occurrence of the hardwood sawtimber cover type. However, the horizontal density of vegetation from o.o to 1.5 min height and overstory canopy closure of shagbark hickory (Carya ovata) within the hardwood sawtimber cover type exhibited positive relationships with the abundance of both species. During periods of poor mast, both species also appear to be positively influenced by the combined effects of increased dominance of hickory and soft mast producing tree and shrub species. Management programs that facilitate the maintenance of openings and crop fields, an abundance of ground cover, and a variety of dominant and subdominant trees should not only improve habitats for year-round use by squirrels but also during periods of low mast availability.

Financial statement fraud is a paradigm that often occurs in Indonesia and causes many losses. Therefore, the aim of this research is to detect the emergence of potential fraud in financial reports using the hexagon fraud theory. In the hexagon fraud theory, there are six dominant factors that can trigger fraud in financial reports: pressure, opportunity, rationalization, ability, arrogance, and collusion. Pressure is proxied by financial targets, financial stability, and financial need; opportunity is proxied by the nature of industry and ineffective monitoring; rationalization is proxied by a change auditor as a proxy for capability to become and change in director; arrogance is proxied by political connections and the frequent number of CEOs; and collusion is proxied by projects with the government. In this research, the dependent variable is measured using the Jones model. The purposeful sampling technique was used in this research in order to obtain a population sample with the criteria of state-owned companies listed on the Indonesia Stock Exchange during the last 5 years, namely, 2018–2022. The quantitative method is supported by multiple regression analysis techniques using the SPSS 26 analysis tool in this research. The results of this research show that the variables financial target, financial stability, personal financial need, nature of industry, ineffective monitoring, change in auditor, change in directors, and political connection have no influence on the potential for fraudulent financial statements. Frequent CEO pictures and collaboration projects with the government have a positive and significant effect on the potential for fraudulent financial statements

Dalam konteks globalisasi dan persaingan bisnis yang ketat, promosi jabatan merupakan aspek strategis yang esensial bagi kelangsungan hidup dan pertumbuhan organisasi. Keputusan promosi yang objektif dan merata tidak hanya meningkatkan motivasi karyawan tetapi juga memaksimalkan potensi sumber daya manusia, meningkatkan produktivitas organisasi. Namun, penilaian kelayakan kandidat untuk promosi seringkali dihadapkan pada tantangan evaluasi kriteria yang kompleks dan subjektif. Penelitian ini bertujuan untuk mengembangkan Sistem Pendukung Keputusan (SPK) untuk promosi jabatan yang mempermudah pengambil keputusan menentukan pilihan yang objektif dan efisien dengan menggabungkan metode Rank Reciprocal (RR) dan Composite Performance Index (CPI). Metode RR mengurangi bias penilaian subjektif dengan memberikan bobot terbalik berdasarkan peringkat kriteria, sedangkan CPI mengintegrasikan berbagai dimensi kinerja menjadi satu indeks komprehensif, memungkinkan evaluasi holistik dari setiap kandidat. Output hasil perhitungan SPK yang diperoleh secara manual dalam studi kasus sesuai dengan output sistem, menunjukkan keabsahan perhitungan sistem. Disamping itu, hasil pengujian menggunakan pendekatan black-box testing juga memperlihatkan kemampuan sistem dalam menjalankan fungsinya dengan baik.

In the ongoing era of digital transformation, the use of information technology has become essential in digitizing business processes across various sectors, including the tender process for procuring goods and services. Manual tender processes often face several challenges, such as being time-consuming, prone to human errors, and inefficient. In the Procurement and Investment Function Division 1 of PT. United Tractors, the tender process for optional safety device items is still conducted manually, creating complexity and consuming a significant amount of time. This research proposes the development of an Android-based application, named Easy Tender, to automate most stages of the tender process. The application is designed to include features such as participant registration, tender participant confirmation, automatic winner determination based on the lowest price and set deadlines, and sorting ranking in the tender recap using the Bubble Sort algorithm. Additionally, the application provides ease of digitalized negotiation and allows real-time monitoring of the tender process. With the development of Easy Tender, it is expected that the Procurement and Investment Function Division 1 of PT. United Tractors can digitize their tender processes, making the tender process more efficient, time-saving, and reducing the risk of human errors. This application is also expected to enhance accountability in determining the winner based on the lowest price. Therefore, this research holds high urgency in efforts to improve operational efficiency and the application of information technology in the business world.
