Fulltext Exploratory study of brain waves and corresponding brain regions of fatigue on-call doctors using quantitative electroencephalogram

Xavier G, Su Ting A, Fauzan N

J Occup Health, 2020 Jan;62(1):e12121.
PMID: 32515890 DOI: 10.1002/1348-9585.12121

OBJECTIVES: It is common to find doctors working long and odd hours and many at times without rest and sleep. Despite the evidence of adverse risk, jeopardizing patient safety under the hands of fatigue doctors under such working hours has not changed in many places. It has argued that with such training and subsequent experience, such issues with patient safety reduce. Fatigue too is argued as subjective, as those who can withstand the stress still perform. Nevertheless, undeniably working under fatigue is not safe for both the patient and the doctor. This study is a novel attempt to explore and objectify the state of fatigue using quantitative EEG among post-call doctors.
METHOD: Seven volunteer post-call doctors were recruited to go through an EEG recording before and after their on-call rotation while at rest and subsequently while carrying out Stroop Test, putting their cognitive function at work.
RESULTS: The doctors have worked up to 33 hours in a row and have had sleep of an average of 1.5 hours. It is found that during task there is a statistically significant increase in theta (frontal and occipital regions) and beta (occipital region) band power while at task post-call. Alpha band power is increased in the frontal and reduced in other regions. Correlation with Stroop Test results indicated that those who have higher alpha, beta, and lower relative theta powers at the frontal region at post-call rest have higher percentage of correct congruent trials.
CONCLUSION: The results objectively imply that these fatigue doctors are under more strain while carrying out a task and corresponds to the implicated regions of brain stimulated by the task accordingly.

Fulltext Illumination Intelligent Adaptation and Analysis Framework: A comprehensive solution for enhancing nighttime driving fatigue monitoring

Tian Z, Albakry NS, Du Y

PLoS One, 2024;19(8):e0308201.
PMID: 39141655 DOI: 10.1371/journal.pone.0308201

Nighttime driving presents a critical challenge to road safety due to insufficient lighting and increased risk of driver fatigue. Existing methods for monitoring driver fatigue, mainly focusing on behavioral analysis and biometric monitoring, face significant challenges under low-light conditions. Their effectiveness, especially in dynamic lighting environments, is limited by their dependency on specific environmental conditions and active driver participation, leading to reduced accuracy and practicality in real-world scenarios. This study introduces a novel 'Illumination Intelligent Adaptation and Analysis Framework (IIAAF)', aimed at addressing these limitations and enhancing the accuracy and practicality of driver fatigue monitoring under nighttime low-light conditions. The IIAAF framework employs a multidimensional technology integration, including comprehensive body posture analysis and facial fatigue feature detection, per-pixel dynamic illumination adjustment technology, and a light variation feature learning system based on Convolutional Neural Networks (CNN) and time-series analysis. Through this integrated approach, the framework is capable of accurately capturing subtle fatigue signals in nighttime driving environments and adapting in real-time to rapid changes in lighting conditions. Experimental results on two independent datasets indicate that the IIAAF framework significantly improves the accuracy of fatigue detection under nighttime low-light conditions. This breakthrough not only enhances the effectiveness of driving assistance systems but also provides reliable scientific support for reducing the risk of accidents caused by fatigued driving. These research findings have significant theoretical and practical implications for advancing intelligent driving assistance technology and improving nighttime road safety.

Khachatryan V, Sirunyan AM, Tumasyan A, Adam W, Asilar E, Bergauer T, et al.

Phys Rev Lett, 2016 Jan 22;116(3):032301.
PMID: 26849587 DOI: 10.1103/PhysRevLett.116.032301

The production cross sections of the B^{+}, B^{0}, and B_{s}^{0} mesons, and of their charge conjugates, are measured via exclusive hadronic decays in p+Pb collisions at the center-of-mass energy sqrt[s_{NN}]=5.02 TeV with the CMS detector at the CERN LHC. The data set used for this analysis corresponds to an integrated luminosity of 34.6 nb^{-1}. The production cross sections are measured in the transverse momentum range between 10 and 60 GeV/c. No significant modification is observed compared to proton-proton perturbative QCD calculations scaled by the number of incoherent nucleon-nucleon collisions. These results provide a baseline for the study of in-medium b quark energy loss in Pb+Pb collisions.

Andrew Chin RW, Chua YY, Chu MN, Mahadi NF, Wong MS, Yusoff MSB, et al.

J Taibah Univ Med Sci, 2018 Feb;13(1):1-9.
PMID: 31435296 DOI: 10.1016/j.jtumed.2017.06.003

Introduction: The Copenhagen Burnout Inventory (CBI) is a recent burnout measure with a focus on fatigue and exhaustion. It has three factors: personal burnout, work-related burnout, and client-related burnout. This study aimed to translate the CBI into the Malay language and to validate the translated version among a group of medical students.

Methods: The forward-backward translation was performed as per standard guidelines. The Malay version of CBI (CBI-M) was distributed to 32 medical students to assess face validity and later to 452 medical students to assess construct validity. The data analysis was performed by Microsoft Excel, SPSS and AMOS.

Results: The face validity index of CBI-M was more than 0.8. The three factors of CBI-M achieved good levels of goodness-of-fit indices (Cmin/df = 2.99, RMSEA = 0.066, GFI = 0.906, CFI = 0.938, NFI = 0.910, TLI = 0.925). The composite reliability values of the three factors ranged from 0.84 to 0.87. The Cronbach's alpha values of the three factors ranged from 0.83 to 0.87.

Conclusions: This study supports the face and construct validity of the CBI-M with a high internal consistency.

PMID: 33546387 DOI: 10.3390/polym13040483

The main purpose of this research is to design a high-fatigue performance hoop wrapped compressed natural gas (CNG) composite cylinder. To this end, an optimization algorithm was presented as a combination of finite element simulation (FES) and response surface analysis (RSA). The geometrical model was prepared as a variable wall-thickness following the experimental measurements. Next, transient dynamic analysis was performed subjected to the refueling process, including the minimum and maximum internal pressures of 20 and 200 bar, respectively. The time histories of stress tensor components were extracted in the critical region. Furthermore, RSA was utilized to investigate the interaction effects of various polymer composite shell manufacturing process parameters (thickness and fiber angle) on the fatigue life of polymer composite CNG pressure tank (type-4). In the optimization procedure, four parameters including wall-thickness of the composite shell in three different sections of the CNG tank and fiber angle were considered as input variables. In addition, the maximum principal stress of the component was considered as the objective function. Eventually, the fatigue life of the polymer composite tank was calculated using stress-based failure criterion. The results indicated that the proposed new design (applying optimal parameters) leads to improve the fatigue life of the polymer composite tank with polyethylene liner about 2.4 times in comparison with the initial design.

Fulltext Deformation Properties of Rubberized ECC Incorporating Nano Graphene Using Response Surface Methodology

Hau Hong DL, Mohammed BS, Al-Fakih A, Wahab MMA, Liew MS, Amran YHM

Materials (Basel), 2020 Jun 24;13(12).
PMID: 32599798 DOI: 10.3390/ma13122831

Engineered cementitious composite (ECC) was discovered as a new substitute of conventional concrete as it provides better results in terms of tensile strain, reaching beyond 3%. From then, more studies were done to partially replace crumb rubber with sand to achieve a more sustainable and eco-friendlier composite from the original ECC. However, the elastic modulus of ECC was noticeably degraded. This could bring potential unseen dangerous consequences as the fatigue might happen at any time without any sign. The replacement of crumb rubber was then found to not only bring a more sustainable and eco-friendlier result but also increase the ductility and the durability of the composite, with lighter specific gravity compared to conventional concrete. This study investigated the effects of crumb rubber (CR) and graphene oxide (GO) toward the deformable properties of rubberized ECC, including the compressive strength, elastic modulus, Poisson's ratio, and drying shrinkage. Central composite design (CCD) was utilized to provide 13 reasonable trial mixtures with the ranging level of CR replacement from 0-30% and that of GO from 0.01-0.08%. The results show that GO increased the strength of the developed GO-RECC. It was also found that the addition of CR and GO to ECC brought a notable improvement in mechanical and deformable properties. The predicted model that was developed using response surface methodology (RSM) shows that the variables (compression strength, elastic modulus, Poisson's ratio, and drying shrinkage) rely on the independent (CR and GO) variables and are highly correlated.

Electrical stimulator with mechanomyography-based real-time monitoring, muscle fatigue detection, and safety shut-off: a pilot study

Naeem J, Hamzaid NA, Azman AW, Bijak M

Biomed Tech (Berl), 2020 Aug 27;65(4):461-468.
PMID: 32304295 DOI: 10.1515/bmt-2019-0191

Functional electrical stimulation (FES) has been used to produce force-related activities on the paralyzed muscle among spinal cord injury (SCI) individuals. Early muscle fatigue is an issue in all FES applications. If not properly monitored, overstimulation can occur, which can lead to muscle damage. A real-time mechanomyography (MMG)-based FES system was implemented on the quadriceps muscles of three individuals with SCI to generate an isometric force on both legs. Three threshold drop levels of MMG-root mean square (MMG-RMS) feature (thr50, thr60, and thr70; representing 50%, 60%, and 70% drop from initial MMG-RMS values, respectively) were used to terminate the stimulation session. The mean stimulation time increased when the MMG-RMS drop threshold increased (thr50: 22.7 s, thr60: 25.7 s, and thr70: 27.3 s), indicating longer sessions when lower performance drop was allowed. Moreover, at thr70, the torque dropped below 50% from the initial value in 14 trials, more than at thr50 and thr60. This is a clear indication of muscle fatigue detection using the MMG-RMS value. The stimulation time at thr70 was significantly longer (p = 0.013) than that at thr50. The results demonstrated that a real-time MMG-based FES monitoring system has the potential to prevent the onset of critical muscle fatigue in individuals with SCI in prolonged FES sessions.

MyJurnal

A numerical study is conducted to determine the Vortex Induced Motion (VIM) effects on Deep-Draft Semi-Submersibles (DDSS). The VIM phenomena is a crucial problem that can cause severe impact on the fatigue life of mooring risers in DDSS. Therefore, a comprehensive numerical simulation is conducted using the Acusolve computational fluid dynamics (CFD) software. Five models of immersed columns with different aspect ratios (ie. 0.6, 0.8, 1.0, 1.2 and 1.4) are numerically investigated under two different incidence angles, which are 0° and 45°. The transverse and in-line vibration amplitude, amplitude of lift force coefficient and vortex shedding are analyzed. The numerical measurements are obtained to see the response of horizontal plane motions, which are transverse, in line and yaw motions. This study with detailed numerical results from parametric data will contribute future studies and the comparisons are made to demonstrate the capability of the present CFD approach.

MyJurnal

Rapid development of technology has made simulator as a promising training tool. Advantages offered such as interactive and realistic training environments, mistake tolerance and training in hazardous scenario without causing harm to trainee, cost effectiveness, opportunity of training review and training time flexibility makes simulator widely used in aviation training, driver training, medical training and rehabilitation. Despite of these advantages, a major drawback of simulator is simulator sickness. Simulator sickness is a condition caused by inconsistency perceived by our vestibular system. Effected individual reported that they are experiencing nausea, fatigue, postural instability, headaches and difficulty in focusing which linger for hours or days in some cases. This paper will discuss the simulator usage and simulator sickness condition in Malaysia as experienced by researchers and a few organizations that use simulator as their training tool.

Fulltext Material Characterization of a Magnetorheological Fluid Subjected to Long-Term Operation in Damper

Utami D, Ubaidillah, Mazlan SA, Imaduddin F, Nordin NA, Bahiuddin I, et al.

Materials (Basel), 2018 Nov 06;11(11).
PMID: 30404193 DOI: 10.3390/ma11112195

This paper investigates the field-dependent rheological properties of magnetorheological (MR) fluid used to fill in MR dampers after long-term cyclic operation. For testing purposes, a meandering MR valve was customized to create a double-ended MR damper in which MR fluid flowed inside the valve due to the magnetic flux density. The test was conducted for 170,000 cycles using a fatigue dynamic testing machine which has 20 mm of stroke length and 0.4 Hz of frequency. Firstly, the damping force was investigated as the number of operating cycles increased. Secondly, the change in viscosity of the MR fluid was identified as in-use thickening (IUT). Finally, the morphological observation of MR particles was undertaken before and after the long-term operation. From these tests, it was demonstrated that the damping force increased as the number of operating cycles increases, both when the damper is turn on (on-state) and off (off-state). It is also observed that the particle size and shape changed due to the long operation, showing irregular particles.

Chronic fatigue syndrome (CFS) is a chronic debilitating condition affecting both physical and mental functioning. It was first quoted as a 'new disease' spreading in the developed countries. It bei:ame a major issue by doctors, professionals and the media for the past 15 years. CFS was not only affecting the adults but childhood fatigue has also been noted. The CFS patients commonly described themselves to be perfectionists, highly driven, energetic U1d motivated before the condition started. Studies have been focused on the definition, diagnosis and management of CFS. However, the understanding of CFS and what cause it is stili unclear and controversial. Thus the aetiological factors of CFS are reviewed in this article. KEYWORDS; Chronic fatigue syndrome (CFS), Aetiology, Psychiatric disorders, Viral infection, Immunology

PMID: 37303065 DOI: 10.1186/s12906-023-04028-2

BACKGROUND: Chemotherapy is associated with a wide range of physical and psychological side effects, so complementary and alternative therapies may be practiced as an independent treatment or combined with the standard ones to improve health-related quality of life of cancer patients. Laughter yoga has predominantly been used as a complementary therapy to enhance health and wellbeing of ordinary people and patients with chronic diseases. However, to date, few studies have evaluated the effects of this modern exercise on cancer patients undergoing chemotherapy in clinical settings, to the best of the authors' knowledge. the present study aimed to investigate the effects of Laughter Yoga on the health-related quality of life of cancer patients undergoing chemotherapy.
METHODS: This study was a two-group randomized clinical trial on 69 cancer patients undergoing chemotherapy at Reza Radiotherapy and Oncology Center, Iran in 2018. Patients were randomly divided into intervention and control groups. The intervention group received laughter yoga for four sessions at one-week intervals. Each session consists of one part and lasts for 20-30 min. Patients' health-related quality of life was assessed before and after the laughter yoga sessions using Quality of Life Questionnaire European Organization for Research and Treatment of Cancer (EORTC QLQ-C30) version 3.0. SPSS Statistics (v.20 software was used to conduct Chi-square, independent t-test, Mann-Whitney, Wilcoxon and paired t-tests analyses of the data.
RESULTS: The number of participants in intervention and control groups were 34 and 35, there was no significant difference of demographic and disease related characteristics and pre-intervention HRQOL between two groups. In the intervention group, there is significant difference between pre- and post-intervention scores (Mean ± Standard Deviation) of emotional functioning (12.99 ± 10.49), physical functioning (0.78 ± 6.08), role functioning (3.43 ± 7.97), fatigue (-8.82 ± 22.01), pain (-8.33 ± 11.78), sleep disturbance (-15.68 ± 18.77), and global health and quality of life (6.37 ± 5.04) (p

PMID: 38330067 DOI: 10.1371/journal.pone.0298094

Recently, global interest in organizing the functioning of renewable energy resources (RES) through microgrids (MG) has developed, as a unique approach to tackle technical, economic, and environmental difficulties. This study proposes implementing a developed Distributable Resource Management strategy (DRMS) in hybrid Microgrid systems to reduce total net percent cost (TNPC), energy loss (Ploss), and gas emissions (GEM) while taking the cost-benefit index (CBI) and loss of power supply probability (LPSP) as operational constraints. Grey Wolf Optimizer (GWO) was utilized to find the optimal size of the hybrid Microgrid components and calculate the multi-objective function with and without the proposed management method. In addition, a detailed sensitivity analysis of numerous economic and technological parameters was performed to assess system performance. The proposed strategy reduced the system's total net present cost, power loss, and emissions by (1.06%), (8.69%), and (17.19%), respectively compared to normal operation. Firefly Algorithm (FA) and Particle Swarm Optimization (PSO) techniques were used to verify the results. This study gives a more detailed plan for evaluating the effectiveness of hybrid Microgrid systems from a technical, economic, and environmental perspective.

Fulltext Individual evaluation of fatigue at work to enhance the safety performance in the construction industry: A systematic review

Heng PP, Mohd Yusoff H, Hod R

PLoS One, 2024;19(2):e0287892.
PMID: 38324557 DOI: 10.1371/journal.pone.0287892

The construction industry is recognized as one of the most hazardous industries globally due to the dynamic on site activities and labour-intensive characteristics. The construction tasks are physically and cognitively demanding therefore the construction workers are prone to work fatigue which compromises safety performance. The evaluation of fit for duty, or fitness for work (FFW) aims to determine if workers are at risk of adverse impacts of ill-health, injury or accidents. This systematic review aimed to critically summarize up-to-date measures and evaluation tools that were employed to monitor work fitness or fatigue specifically among construction workers. Adhering with the PRISMA protocol, three databases were searched from the inception to 2022, with a total combination of 37 keywords, concluding to the selection of 20 relevant articles. The Mixed Method Appraisal Tool (MMAT) was used as the guide for the study appraisal. A total of 20 articles were reviewed, published from 2008-2022. Majority of the studies employed experimental design. The review identified the subjective evaluation scales and objective measurement tool. The subjective self-response questionnaires can be categorized into single dimension or multidimension covering both physical and mental fitness; whereas the objective measurement tool can be categorized into physiological metrics, physical and cognitive performance measure. The available scientific evidence has raised the relevant issues for on-site practicality and potentially guide the formulation of evidence-based guidelines for the FFW assessment in the construction industry.

PMID: 27094349 DOI: 10.1113/EP085795

What is the central question of this study? Acute and repetitive cryotherapy are routinely used to accelerate postexercise recovery, although the effect on resident immune cells and repetitive exposure has largely been unexplored and neglected. What is the main finding and its importance? Using blood-derived mononuclear cells and semi-professional mixed martial artists, we show that acute and repetitive cryotherapy reduces the in vitro and in vivo T-cell and monocyte activation response whilst remaining independent of the physical performance of elite athletes. We investigated the effect of repetitive cryotherapy on the in vitro (cold exposure) and in vivo (cold water immersion) activation of blood-derived mononuclear cells following high-intensity exercise. Single and repeated cold exposure (5°C) of a mixed cell culture (T cells and monocytes) was investigated using in vitro tissue culture experimentation for total neopterin production (neopterin plus 7,8-dihydroneopterin). Fourteen elite mixed martial art fighters were also randomly assigned to either a cold water immersion (15 min at 10°C) or passive recovery protocol, which they completed three times per week during a 6 week training camp. Urine was collected and analysed for neopterin and total neopterin three times per week, and perceived soreness, fatigue, physical performance (broad jump, push-ups and pull-ups) and training performance were also assessed. Single and repetitive cold exposure significantly (P

Fatigue-related crashes have long been the topic of discussion and study worldwide. The relationship between fatigue-related crashes and time of day is well documented. In Malaysia, the possibility of banning express buses from operating during the early-hours of the morning has emerged as an important consideration for passenger safety. This paper highlights the findings of an impact assessment study. The study was conducted to determine all possible impacts prior to the government making any decision on the proposed banning. This study is an example of a simple and inexpensive approach that may influence future policy-making process. The impact assessment comprised two major steps. The first step involved profiling existing operation scenarios, gathering information on crashes involving public express buses and stakeholders' views. The second step involved a qualitative impact assessment analysis using all information gathered during the profiling stage to describe the possible impacts. Based on the assessment, the move to ban early-hour operations could possibly result in further negative impacts on the overall road safety agenda. These negative impacts may occur if the fundamental issues, such as driving and working hours, and the need for rest and sleep facilities for drivers, are not addressed. In addition, a safer and more accessible public transportation system as an alternative for those who choose to travel at night would be required. The proposed banning of early-hour operations is also not a feasible solution for sustainability of express bus operations in Malaysia, especially for those operating long journeys. The paper concludes by highlighting the need to design a more holistic approach for preventing fatigue-related crashes involving express buses in Malaysia.

Ramasamy V, Binti Mat Lazim N, Abdullah B, Singh A

Gulf J Oncolog, 2019 May;1(30):43-51.
PMID: 31242981

INTRODUCTION: Cancer related fatigue (CRF) is a problem experienced by head and neck cancer patients, especially those who undergo chemoradiation therapy. CRF may persist for years post chemoradiation therapy and significantly impair their quality of life (QOL). Tualang honey is rich in amino acids, vitamins, minerals and enzymes. It is proven to have anti-inflammatory, antioxidant and anti-tumour properties. As CRF is related to inflammatory mediators, the effects of Tualang Honey may improve CRF. The aim of this study is to determine if Tualang honey has a role in improving CRF and quality of life among head and neck cancer patients post chemoradiation.
METHODOLOGY: In this open labelled randomized clinical trial, 40 participants aged between 18 and 65 with head and neck cancer who completed chemotherapy and/or radiotherapy in Hospital USM, Kelantan Malaysia or Hospital Taiping were recruited and randomized into two groups: Tualang honey (experimental) group or Vitamin C (control) group. They were prescribed with either daily oral Tualang honey 20mg or vitamin C tablet 100 mg for 8 weeks. Level of fatigue and quality of life were measured using FACIT-Fatigue and FACT H&N questionnaires at baseline, 4 weeks and 8 weeks. The white cell count and C-reactive protein level were also measured at baseline, 4 weeks and 8 weeks.
RESULTS: After four and eight weeks of treatment with Tualang honey or Vitamin C, the fatigue level for experimental group was better than in the control group, and the differences were statistically significant (p<0.05). Statistically significant improvements were seen on quality of life (p<0.05) for the experimental group at week 8, however, no significant improvements were seen in white cell count and C-reactive protein level between control and experimental group.
CONCLUSION: Our research provided support for the use of Tualang honey to improve CRF and QOL in head and neck cancer patients post chemotherapy or radiotherapy.

Letchmi S, Das S, Halim H, Zakariah FA, Hassan H, Mat S, et al.

Nurs Health Sci, 2011 Mar;13(1):60-4.
PMID: 21392194 DOI: 10.1111/j.1442-2018.2011.00579.x

The fatigue that is observed in patients who are undergoing dialysis is usually associated with an impaired quality of life. The present cross-sectional study was conducted from January to April 2009 in three hemodialysis units in Kuala Lumpur, Malaysia. In this study, the Multidimensional Fatigue Inventory and Depression Anxiety and Stress Score 21 were used to determine the level of fatigue, depression, anxiety, and stress of patients who were undergoing dialysis. The data were obtained from a calculated sample of 116 and a total of 103 respondents participated in the study. A total of 56 (54.4%) and 47 (45.6%) respondents experienced a high level and a low level of fatigue, respectively. There was a significant relationship between the duration of treatment and the level of fatigue. The respondents who had been receiving treatment for > 2 years experienced more fatigue, compared to the respondents who had been undergoing hemodialysis for > 2 years. There was a significant difference in relation to the age of the participants regarding the level of fatigue. No significant relationship between the sex of the participants, anemia, depression, anxiety, stress, and the level of fatigue was observed. Special attention needs to be paid to both the younger and older adults who are receiving treatment. In addition, proper planning is needed for the patients regarding their daily activities in order to reduce fatigue. Nurses who work in hemodialysis units are recommended to provide exercise classes or group therapy in order to boost the energy levels among patients who are undergoing dialysis. Health professionals should provide appropriate treatment for patients who are experiencing fatigue in order to prevent any other complications that could arise.

Fulltext Developing a digital intervention for cancer survivors: an evidence-, theory- and person-based approach

Bradbury K, Steele M, Corbett T, Geraghty AWA, Krusche A, Heber E, et al.

NPJ Digit Med, 2019;2:85.
PMID: 31508496 DOI: 10.1038/s41746-019-0163-4

This paper illustrates a rigorous approach to developing digital interventions using an evidence-, theory- and person-based approach. Intervention planning included a rapid scoping review that identified cancer survivors' needs, including barriers and facilitators to intervention success. Review evidence (N = 49 papers) informed the intervention's Guiding Principles, theory-based behavioural analysis and logic model. The intervention was optimised based on feedback on a prototype intervention through interviews (N = 96) with cancer survivors and focus groups with NHS staff and cancer charity workers (N = 31). Interviews with cancer survivors highlighted barriers to engagement, such as concerns about physical activity worsening fatigue. Focus groups highlighted concerns about support appointment length and how to support distressed participants. Feedback informed intervention modifications, to maximise acceptability, feasibility and likelihood of behaviour change. Our systematic method for understanding user views enabled us to anticipate and address important barriers to engagement. This methodology may be useful to others developing digital interventions.
