  1. Fulltext Smart Helmet 5.0 for Industrial Internet of Things Using Artificial Intelligence
    Campero-Jurado I, Márquez-Sánchez S, Quintanar-Gómez J, Rodríguez S, Corchado JM
    Sensors (Basel), 2020 Nov 01;20(21).
    PMID: 33139608 DOI: 10.3390/s20216241
    Information and communication technologies (ICTs) have contributed to advances in Occupational Health and Safety, improving the security of workers. The use of Personal Protective Equipment (PPE) based on ICTs reduces the risk of accidents in the workplace, thanks to the capacity of the equipment to make decisions on the basis of environmental factors. Paradigms such as the Industrial Internet of Things (IIoT) and Artificial Intelligence (AI) make it possible to generate PPE models feasibly and create devices with more advanced characteristics such as monitoring, sensing the environment and risk detection between others. The working environment is monitored continuously by these models and they notify the employees and their supervisors of any anomalies and threats. This paper presents a smart helmet prototype that monitors the conditions in the workers' environment and performs a near real-time evaluation of risks. The data collected by sensors is sent to an AI-driven platform for analysis. The training dataset consisted of 11,755 samples and 12 different scenarios. As part of this research, a comparative study of the state-of-the-art models of supervised learning is carried out. Moreover, the use of a Deep Convolutional Neural Network (ConvNet/CNN) is proposed for the detection of possible occupational risks. The data are processed to make them suitable for the CNN and the results are compared against a Static Neural Network (NN), Naive Bayes Classifier (NB) and Support Vector Machine (SVM), where the CNN had an accuracy of 92.05% in cross-validation.

    Alawi M, Lee PF, Deng ZD, Goh YK, Croarkin PE
    J Neural Eng, 2023 Mar 16;20(2).
    PMID: 36240726 DOI: 10.1088/1741-2552/ac9a76
    Objective. The therapeutic application of noninvasive brain stimulation modalities such as transcranial magnetic stimulation (TMS) has expanded in terms of indications and patient populations. Often neurodevelopmental and neurodegenerative changes are not considered in research studies and clinical applications. This study sought to examine TMS dosing across time points in the life cycle.Approach. TMS induced electric fields with a figure-of-eight coil was simulated at left dorsolateral prefrontal cortex regions and taken in vertex as a control region. Realistic magnetic resonance imaging-based head models (N= 48) were concurrently examined in a cross-sectional study of three different age groups (children, adults, and elderlies).Main results. Age had a negative correlation with electric field peaks in white matter, grey matter and cerebrospinal fluid (P< 0.001). Notably, the electric field map in children displayed the widest cortical surface spread of TMS induced electric fields.Significance. Age-related anatomical geometry beneath the coil stimulation site had a significant impact on the TMS induced electric fields for different age groups. Safety considerations for TMS applications and protocols in children are warranted based on the present electric field findings.

  3. Fulltext Cathepsin-K inhibition enhances anti-cancerous activity within oral squamous cell carcinoma cells: Uncloaking the potency of new K21 formulation
    Imad R, Sheikh Z, Rao Pichika M, Kit-Kay M, Siddiqui RA, Nawaid Shah SN, et al.
    Exp Cell Res, 2023 Sep 01;430(1):113687.
    PMID: 37356748 DOI: 10.1016/j.yexcr.2023.113687
    BACKGROUND: The ability of cancer cells to be invasive and metastasize depend on several factors, of which the action of protease activity takes center stage in disease progression.

    PURPOSE/OBJECTIVE: To analyze function of new K21 molecule in the invasive process of oral squamous cell carcinoma (OSCC) cell line.

    MATERIALS & METHODS: The Fusobacterium (ATCC 23726) streaks were made, and pellets were resuspended in Cal27 (ATCC CRL-2095) OSCC cell line spheroid cell microplate. Cells were seeded and Lysotracker staining performed for CathepsinK red channel. Cell and morphology were evaluated using Transmission Electron microscopy. Thiobarbituric acid assay was performed. OSCC was analyzed for Mic60. Raman spectra were collected from the cancer cell line. L929 dermal fibroblast cells were used for Scratch Assay. ELISA muti arrays were used for cytokines and matrix molecules. Internalization ability of fibroblast cells were also analyzed. Structure of K21 as a surfactant molecule with best docked poses were presented.

    RESULTS: Decrease in lysosomal staining was observed after 15 and 30 min of 0.1% treatment. Tumor clusters were associated with cell membrane destruction in K21 primed cells. There was functional silencing of Mic60 via K21, especially with 1% concentration with reduced cell migration and invasiveness. Raman intensity differences were seen at 700 cm-1, 1200 cm-1 and 1600 cm-1 regions. EVs were detected within presence of fibroblast cells amongst K21 groups. Wound area and wound closure showed the progress of wound healing.

    CONCLUSION: Over expression of CatK can be reduced by a newly developed targeted K21 based drug delivery system leading to reduced migration and adhesion of oral squamous cell carcinoma cells. The K21 drug formulation can have great potential for cancer therapies due to targeting and cytotoxicity effects.

    Maj MK, Ar AH, Das S
    Chang Gung Med J, 2011;34(6 Suppl):13-6.
    PMID: 22490452
    A slipped upper femoral epiphysis (SUFE) is a known hip disorder in adolescents in which the proximal femoral epiphysis slips and displaces relative to the metaphysis. We report an obese 12-year-old boy who presented with acute pain in the left hip after a fall. He was otherwise healthy with no prior joint pain. Pelvic radiography was misread twice before a second fall led to a severe SUFE.

  8. Fulltext The aerodynamic cost of head morphology in bats: maybe not as bad as it seems
    Vanderelst D, Peremans H, Razak NA, Verstraelen E, Dimitriadis G, Dimitriadis G
    PLoS One, 2015;10(3):e0118545.

    At first sight, echolocating bats face a difficult trade-off. As flying animals, they would benefit from a streamlined geometric shape to reduce aerodynamic drag and increase flight efficiency. However, as echolocating animals, their pinnae generate the acoustic cues necessary for navigation and foraging. Moreover, species emitting sound through their nostrils often feature elaborate noseleaves that help in focussing the emitted echolocation pulses. Both pinnae and noseleaves reduce the streamlined character of a bat's morphology. It is generally assumed that by compromising the streamlined charactered of the geometry, the head morphology generates substantial drag, thereby reducing flight efficiency. In contrast, it has also been suggested that the pinnae of bats generate lift forces counteracting the detrimental effect of the increased drag. However, very little data exist on the aerodynamic properties of bat pinnae and noseleaves. In this work, the aerodynamic forces generated by the heads of seven species of bats, including noseleaved bats, are measured by testing detailed 3D models in a wind tunnel. Models of Myotis daubentonii, Macrophyllum macrophyllum, Micronycteris microtis, Eptesicus fuscus, Rhinolophus formosae, Rhinolophus rouxi and Phyllostomus discolor are tested. The results confirm that non-streamlined facial morphologies yield considerable drag forces but also generate substantial lift. The net effect is a slight increase in the lift-to-drag ratio. Therefore, there is no evidence of high aerodynamic costs associated with the morphology of bat heads.

  9. Fulltext Acetabulum Protrusion Following Ceramic Liner Fracture: A Case Report
    Aytekin K, Esenyel CZ
    Malays Orthop J, 2018 Mar;12(1):45-47.
    PMID: 29725513 DOI: 10.5704/MOJ.1803.010
    Hip arthroplasty is an extremely satisfying treatment method for coxarthrosis which is in increasing use throughout the world. However, loosening of the prosthesis is a significant complication and to overcome this, ceramic liners are increasingly being selected. If the survival of ceramic surfaces is prolonged, there is a risk of fracture of the ceramic materials. New ceramic materials developed to overcome this problem are more resistant. The case presented here is of a patient in whom liner fracture developed following ceramic-ceramic hip arthroplasty. The ceramic femoral head was observed to have protruded into the defect created in the acetabular component. Acetabular revision was applied to the patient.

  10. Factors associated with the enactment of safety belt and motorcycle helmet laws
    Law TH, Noland RB, Evans AW
    Risk Anal, 2013 Jul;33(7):1367-78.
    PMID: 23106188 DOI: 10.1111/j.1539-6924.2012.01916.x
    It has been shown that road safety laws, such as motorcycle helmet and safety belt laws, have a significant effect in reducing road fatalities. Although an expanding body of literature has documented the effects of these laws on road safety, it remains unclear which factors influence the likelihood that these laws are enacted. This study attempts to identify the factors that influence the decision to enact safety belt and motorcycle helmet laws. Using panel data from 31 countries between 1963 and 2002, our results reveal that increased democracy, education level, per capita income, political stability, and more equitable income distribution within a country are associated with the enactment of road safety laws.

    Ng BH, Tan JK, Andrea Ban YL, Faisal AH
    Med J Malaysia, 2020 03;75(2):181-183.
    PMID: 32281606
    In the past, many case series have reported the effectiveness of autologous blood patch pleurodesis (ABPP) in recurrent secondary spontaneous pneumothorax (SSP), particularly in those who were unfit for surgery. We describe two cases of persistent air leak in pneumoconiosis and pulmonary fibrosis with bronchiectasis, whereby the techniques employed had improved the success rate of ABPP. The determining factors that lead to the success of ABPP were determined by the volume of autologous blood instilled, Trendelenburg position post instillation, and early chest physiotherapy with mobilisation by application of pneumostat.

    Assault injury can occur to any parts of the body. Usually the target area is the head, neck, chest and abdomen as they contain many major structures that are vital for life. However, movement of the victim few seconds before the instrument reach the body can redirect the impact to the less fatal part of the body. The outcome may be less fatal but can lead to cosmetically unacceptable condition. (Copied form article).

  13. Revisiting the social cost of carbon after INDC implementation in Malaysia: 2050
    Sarkar MSK, Al-Amin AQ, Filho WL
    Environ Sci Pollut Res Int, 2019 Feb;26(6):6000-6013.
    PMID: 30612378 DOI: 10.1007/s11356-018-3947-1
    This article projects the social cost of carbon (SCC) and other related consequences of climate change by using Malaysia's intended nationally determined contribution (INDC) and climate vision 2040 (CV2040) by 2050. It compares the projections derived from the Dynamic Integrated Model of the Climate and Economy (DICME) based on the respective INDC and CV2040 scenario. The results reveal that industrial emissions would incur a substantial increase every 5 years under the scenario CV2040, while Malaysia would experience lower industrial emissions in the coming years under the scenario INDC. Emission intensity in Malaysia will be 0.61 and 0.59 tons/capita in 2030 for scenario CV2040 and scenario INDC respectively. Malaysia would face climate damage of MYR456 billion and MYR 49 billion by 2050 under CV2040 and INDC scenario respectively. However, climate damage could be much lower if the INDC regime were adopted, as this scenario would decrease climatic impacts over time. The estimated SSC per ton of CO2 varies between MYR74 and MYR97 for scenario CV2040 and MYR44 and MYR62 for scenario INDC in 2030 and 2050 respectively. Considering different aspects, including industrial emissions, damage cost, and social cost of carbon, INDC is the best policy compared to CV2040. Thus, Malaysia could achieve its emissions reduction target by implementing INDC by 2050.

    The complex pathophysiology of traumatic brain injury, its cascading effects and a varied outcome suggest that factors such as genetics may permeate and modulate the neurocognitive outcomes in patients with mild traumatic brain injury (mTBI). This study was conducted to determine the relationship between genetic polymorphism of apolipoprotein E, and neurocognitive and functional outcomes in mTBI. Twenty-one patients with mTBI were recruited prospectively. The severity of the injury was established with the Glasgow Coma Score (GCS). Other assessments included the CT Scan of the head on admission, Disability Rating Scale, Chessington Occupational Therapy Neurological Assessment (COTNAB) and Glasgow Outcome Scale (GOS). The Spearmen correlation analysis of ApoE allele status and the cognitive and functional assessments saw some association with the Sensory Motor Ability - Coordination (-0.526, p

  15. New head models extracted from thermal infrared (IR) images for dosimetry computations
    Gasmelseed A
    Comput Methods Biomech Biomed Engin, 2011 Jul;14(7):665-71.
    PMID: 21480080 DOI: 10.1080/10255842.2011.563738
    In electromagnetic dosimetry, anatomical human models are commonly obtained by segmentation of magnetic resonance imaging or computed tomography scans. In this paper, a human head model extracted from thermal infrared images is examined in terms of its applicability to specific absorption rate (SAR) calculations. Since thermal scans are two-dimensional (2D) representation of surface temperature, this allows researchers to overcome the extensive computational demand associated with 3D simulation. The numerical calculations are performed using the finite-difference time-domain method with mesh sizes of 2 mm at 900 MHz plane wave irradiation. The power density of the incident plane wave is assumed to be 10 W/m(2). Computations were compared with a realistic anatomical head model. The results show that although there were marked differences in the local SAR distribution in the various tissues in the two models, the 1 g peak SAR values are approximately similar in the two models.

    Juvenile angiofibromas (JAs) are well-characterised in literature, arising typically in the posterolateral wall of the nasal cavity of young males. Numerous theories have been proposed to explain the occurrence of this unique and rare tumour. Angiofibromas originating in other sites within the head and neck have been described but this is exceedingly rare, constituting less than 2% of all diagnosed cases. Extranasopharyngeal angiofibroma is a rare lesion, and more importantly, controversial. It is not known whether it is actually a relative of the well-known JA that is seen exclusively in adolescent males. We present the case of a post-menopausal woman with unilateral nasal obstruction who was unexpectedly diagnosed as nasal septal angiofibroma.

  17. Fulltext Sclerosing odontogenic carcinoma - review of all published cases: is it a justifiable addition as a malignancy?
    Lim D, Tan CC, Tilakaratne WM, Goh YC
    Braz J Otorhinolaryngol, 2021 02 27;88(1):118-129.
    PMID: 33715971 DOI: 10.1016/j.bjorl.2021.01.007
    INTRODUCTION: Sclerosing odontogenic carcinoma was a new addition to the list of head and neck tumors by World Health Organization in 2017. This lesion has scarcely been reported and a lack of pathognomonic markers for diagnosis exists.

    OBJECTIVE: The aim of the study was to summarize findings from the available literature to provide up-to-date information on sclerosing odontogenic carcinoma and to analyse clinical, radiological, and histopathological features to obtain information for and against as an odontogenic malignancy.

    METHODS: We conducted a comprehensive review of literature by searching Pubmed, EBSCO and Web of Science databases, according to PRISMA guidelines. All the cases reported as sclerosing odontogenic carcinoma in English were included. Data retrieved from the articles were gender, age, clinical features, site, relevant medical history, radiographical findings, histopathological findings, immunohistochemical findings, treatments provided and prognosis.

    RESULTS: Mean age at diagnosis of sclerosing odontogenic carcinoma was 54.4 years with a very slight female predilection. Sclerosing odontogenic carcinoma was commonly reported in the mandible as an expansile swelling which can be asymptomatic or associated with pain or paraesthesia. They appeared radiolucent with cortical resorption in radiograph evaluation. Histologically, sclerosing odontogenic carcinoma was composed of epithelioid cells in dense, fibrous, or sclerotic stroma with equivocal perineural invasion. Mild cellular atypia and inconspicuous mitotic activity were observed. There is no specific immunohistochemical marker for sclerosing odontogenic carcinoma. AE1/AE3, CK 5/6, CK 14, CK19, p63 and E-cadherin were the widely expressed markers for sclerosing odontogenic carcinoma. Surgical resection was the main treatment provided with no recurrence in most cases. No cases of metastasis were reported.

    CONCLUSION: From the literature available, sclerosing odontogenic carcinoma is justifiable as a malignant tumor with no or unknown metastatic potential which can be adequately treated with surgical resection. However, there is insufficient evidence for histological grading or degree of malignancy of this tumor.

    Medicine & Health, 2007;2(1):99-102.
    MyJurnal
    Kimura’s disease (KD) is a rare, benign chronic inflammatory disease of unknown aetiology, typically presents in the Orientals as subcutaneous masses in the head and neck region that could be easily misdiagnosed as a malignant tumour, leading to unnecessary radical surgery or intensive cytotoxic therapy. It has been mainly reported in the Chinese and Japanese literature. It is difficult to diagnose before tissue biopsy and fine needle aspiration cytology (FNAC) has limited value. Hence, unless the pathologists are aware of this entity, it might be mistaken as a malignant lesion. We encountered a case of KD in a Malay patient presenting as a parotid mass that was initially diagnosed as Hodgkin’s lymphoma (HL). This disorder should be suspected in young male Asian patients presenting with a painless unilateral mass in the head and neck region with associated hypereosinophilia.

    PMID: 35506809 DOI: 10.32641/andespediatr.v92i6.4030
    The Surviving Sepsis Campaign International Guidelines for the Management of Septic Shock and Sepsis-associated Organ Dysfunction in Children was released in 2020 and is intended for use in all global settings that care for children with sepsis. However, practitioners managing children with sep sis in resource-limited settings (RLS) face several challenges and disease patterns not experienced by those in resource-rich settings. Based upon our collective experience from RLS, we aimed to reflect on the difficulties of implementing the international guidelines. We believe there is an urgent need for more evidence from RLS on feasible, efficacious approaches to the management of sepsis and septic shock that could be included in future context-specific guidelines.

    PMID: 18181897 DOI: 10.1111/j.1365-2354.2007.00814.x
    Being a rapidly developing country, a study was needed to see how we faired in treating head and neck cancer patients compared with international standards. Although being a retrospective study, this research shows that there is still a lot to be done in our developing nation in educating the general public about head and neck cancers as most of them presented in the later stages to us. There also needs to be a proper review about the treatment modality offered to patient as our survival results are far behind in certain categories of cancers compared with the developed nations.
