<Case Report> Fatal Cardiovascular Collapse during Insertion of Bone Cement and a Prosthesis: Two Case Reports

Over the last two decades, hip surgery with methylmethacrylic cement has become a popular and suecessful procedure. Improvements in the techniques of surgery and anesthesia have led to increased numbers of operations in the elderly. However, cardiovascular collapse is an occasional but well documented complication of the use of acrylic bone cement during hip surgery. Although the etiology has not yet been completely resolved, fat or air emboli and hypersensitivity to the methylmethacrylate monomer have been implicated. We have now documented two cases of fatal cardiovascular collapse during orthopedic surgery, presumably resulting from intraoperative fat embolism.journal articl

Research and development of a safe bus driving support system considering passenger discomfort

In recent years, bus accidents have become a social problem due to the aging of bus drivers and the shortage of personnel. Our research group has been developing a safe bus driving support system for reducing bus accidents. About the type of accidents, inside car accidents become critical for fixed-route buses. While recent safe driving support systems using AI detect moving passengers to reduce inside car accidents, the other attributes, e.g. inside car status, age, baggage, use of a smartphone, and so on, are not considered. In this research, we focus on the inside car status, and, detecting passengers' discomfort, e.g. discomfort driving, late schedule, congestion in the car. In this poster presentation, we will introduce the project overview and the related activities.conference pape

Space charge and conduction in LDPE-polypropylene copolymer blends

In the previous paper, the electrical breakdown properties of blend polymers of LDPE and polypropylene copolymer were investigated. The impulse breakdown strength in the high temperature region (90°C) was improved by blending. In the present paper, the space charge behavior and electrical conduction of the blends were studied with the electrode system of aluminium/sample/semiconductive layer. The specimen with 90 wt% LDPE and 10 wt% polypropylene copolymer (B10) had a larger amount of space charge than pure LDPE (PE) at 30°C. On the other hand, the DC current of B10 was less than that of PE in this temperature region. It was found that the anode field was related to the current in both PE and B10, which suggests that the carrier injection from the anode is dominant to the electrical conduction. The DC currents of both PE and B10 showed good straight lines on the Schottky plot with the same Schottky coefficients.journal articl

Rift Valley fever (RVF) is a mosquito-borne viral hemorrhagic disease that affects humans and livestock. In Kenya, the disease has spread to new areas like Baringo County, with a growing realization that the epidemiology of the virus may also include endemic transmission. Local knowledge of a disease in susceptible communities is a major driver of prevention and control efforts. A cross-sectional survey using a semi-structured questionnaire was conducted in five locations of Baringo South that had reported RVF cases during the last outbreak, to determine the knowledge, attitude and perception of the predominantly agro-pastoralist community to RVF. Knowledge of RVF clinical signs, transmission, risk factors and prevention all contributed to the total knowledge score. Additionally, the respondents’ attitude was based on their awareness of the threat posed by RVF and preparedness to take appropriate measures in case of suspected infection. Out of the 300 respondents, 80% had heard about the disease, however, only 9.6% attained at least half of the total knowledge score on RVF. Nevertheless, 86% recognized the threat it posed and knew the appropriate action to take in suspected human and livestock cases (positive attitude). Factors significantly associated with a better knowledge of RVF included higher education level, being Maasai, higher socio-economic index, old age and history of RVF in household members and livestock. Being Maasai and a higher socio-economic index were significantly associated with a positive attitude. The low level of knowledge exhibited by the respondents could be due to progressive loss of interest and information associated with a prolonged inter-outbreak period. This calls for regular awareness campaigns. More emphasis should also be put on educating communities on the role played by the mosquito vector in the epidemiology of RVF. The most promising routes of disseminating this information are radio and community gatherings.</div
