International Journal of Sport Management, Recreation & Tourism , 2012,
Abstract: The present study examines the effects of physical module elements (adventure based activity) included in the Malaysian National Service Programme and to investigate the socio-demographic variables impact on team cohesion building among the participants. In this study, the participants were selected from three different camps, namely, Tasoh camp, Guar Chenderai camp and Meranti camp, located in the state of Perlis, Malaysia. The participants were those from the second batch intake in the year 2007. The sample sizes comprised of 994 participants (480=males, 514=females). The present study applied a pre-test and post-test design. The group was tested before and after the programme. This design was chosen because it could measure the impacts of the adventure-based activity towards team cohesion over time through the pre- and post-test scores (Berg & Latin, 2004). The variables comprised of the demographic factors (age, gender and place of residence), which included team cohesion were measured by Group Environmental Questionnaire (GEQ) (Carron, Widmeyer, & Brawley, 1985). Results indicated that the participants of the National Service Training Programme underwent group cohesion change during the Physical Module activities (adventure based activities) that were carried out at the camp. The changes were observable based on the statistically analyzed data during the pre and post-test.

Abstract:
White water kayaking is the fun sport on fast moving water, typically call white water river. The element of fun and challenge has attracted many people to join this adventure sports in Malaysia. This study examined the risk in adventure sport tourism by white water kayakers in Malaysia. The objective of this study is to reveal the injuries suffered by whitewater kayakers during activity. This 2013 survey will be described using descriptive data only. The survey forms were distributed via kayak clubs and associations under the auspices of the Malaysian Canoe Association (MASCA). The survey asked respondents about their previous injuries during white water kayaking activities. All the data concerning to age, sex, experience and ability was collected from them. A total of 217 respondents provided feedback on this survey. Of the total 217, about 186 respondents experienced injuries during an activity, while the rest did not suffer any injuries while they were kayaking. The result showed only 41% seeks medical attention after injury. These whitewater kayaking activities require physical exertion as well as emotional and mental stability. Good practise and skill can help kayakers avoid injuries and accident during paddling session. This sport has been developing and growing each year. Future studies can also be done by looking for new discipline in white water which is “playboating” which may find different risk and injury.

Abstract: Although Streptococcus pneumoniae is a leading cause of childhood disease in South East Asia, little has previously been reported regarding the epidemiology of invasive pneumococcal disease in Malaysia and very few studies have explored pneumococcal epidemiology using multilocus sequence typing (MLST). Here we describe serotype, multilocus sequence type (ST), and penicillin susceptibility of thirty pneumococcal invasive disease isolates received by the University of Malaya Medical Centre between February 2000 and January 2007 and relate this to the serotypes included in current pneumococcal conjugate vaccines. A high level of diversity was observed; fourteen serotypes and 26 sequence types (ST), (11 of which were not previously described) were detected from 30 isolates. Penicillin non-susceptible pneumococci accounted for 33% of isolates. The extent of molecular heterogeneity within carried and disease-causing Malaysian pneumococci remains unknown. Larger surveillance and epidemiological studies are now required in this region to provide robust evidence on which to base future vaccine policy.

Abstract: Diseases of the tonsils are becoming more resistant to antibiotics due to the persistence of bacteria through the formation of biofilms. Therefore, understanding the microbiology and pathophysiology of such diseases represent an important step in the management of biofilm-related infections. We have isolated the microorganisms, evaluated their antimicrobial susceptibility, and detected the presence of bacterial biofilms in tonsillar specimens in correlation with the clinical manifestations of tonsillar diseases. Therefore, a total of 140 palatine tonsils were collected from 70 patients undergoing tonsillectomy at University Malaya Medical Centre. The most recovered isolate was Staphylococcus aureus (39.65%) followed by Haemophilus influenzae (18.53%). There was high susceptibility against all selected antibiotics except for cotrimoxazole. Bacterial biofilms were detected in 60% of patients and a significant percentage of patients demonstrated infection manifestation rather than obstruction. In addition, an association between clinical symptoms like snore, apnea, nasal obstruction, and tonsillar hypertrophy was found to be related to the microbiology of tonsils particularly to the presence of biofilms. In conclusion, evidence of biofilms in tonsils in correlation with the demonstrated clinical symptoms explains the recalcitrant nature of tonsillar diseases and highlights the importance of biofilm’s early detection and prevention towards better therapeutic management of biofilm-related infections. 1. Introduction The ear, nose, and throat (ENT) represent a natural habitat for a broad range of microorganisms such as commensal bacteria as well as potential pathogens [1]. However, these bacteria can sometimes find their way to overcome the defense barriers of such locations and establish chronic infections that poses a challenge to both medical practice and healthcare system [2]. Infections of the ENT such as tonsillitis are diseases that occur with high frequency [3]. During the past decades, efforts have been made to manage the infectious diseases of tonsils [4]. It has been reported that the impact of tonsillar diseases may not only affect the tonsils alone but it can reach other related anatomic structures like the paranasal sinus, upper aerodigestive tract, and Eustachian tube-middle ear complex [4]. Thus understanding the microbiology and pathophysiology of such diseases represents an important step in the management of biofilm-related infections. Chronic infections of the ear, nose, and throat are becoming more resistant to common antimicrobial

Abstract: Background Quorum sensing is a term that describes an environmental sensing system that allows bacteria to monitor their own population density which contributes significantly to the size and development of the biofilm. Many gram negative bacteria use N-acyl-homoserine lactones as quorum sensing signal molecules. In this study, we sought to find out if the biofilm formation among clinical isolates of Acinetobacter spp. is under the control of autoinducing quorum sensing molecules. Methodology/Principal Findings Biofilm formation among clinical isolates of Acinetobacter spp. was assessed and the production of signal molecules were detected with Chromobacterium violaceum CV026 biosensor system. Characterisation of autoinducers was carried out by mass spectrometric analysis. We have also reported the identification of an autoinducer synthase gene, abaΙ among the isolates that produce quorum sensing signal molecules and have reported that the mutation in the abaI gene influences their biofilm forming capabilities. Using a microtitre-plate assay it was shown that 60% of the 50 Acinetobacter spp. isolates significantly formed biofilms. Further detection with the biosensor strain showed that some of these isolates produced long chain signal molecules. Mass spectrometric analysis revealed that five of these isolates produced N-decanoyl homoserine lactone and two isolates produced acyl-homoserine lactone with a chain length equal to C12. The abaΙ gene was identified and a tetracycline mutant of the abaΙ gene was created and the inhibition in biofilm formation in the mutant was shown. Conclusions/Significance These data are of great significance as the signal molecules aid in biofilm formation which in turn confer various properties of pathogenicity to the clinical isolates including drug resistance. The use of quorum sensing signal blockers to attenuate bacterial pathogenicity is therefore highly attractive, particularly with respect to the emergence of multi antibiotic resistant bacteria.

Abstract: nosocomial infections are major clinical threats to hospitalised patients and represent an important source of morbidity and mortality. it is necessary to develop rapid detection assays of nosocomial pathogens for better prognosis and initiation of antimicrobial therapy in patients. in this study, we present the development of molecular methods for the detection of six common nosocomial pathogens including escherichia coli, staphylococcus aureus, streptococcus pneumoniae, klebsiella pneumoniae, pseudomonas aeruginosa and acinetobacter spp. conventional multiplex pcr and sybr green based real time pcr assays were performed using genus and species specific primers. blind testing with 300 clinical samples was also carried out. the two assays were found to be sensitive and specific. eubacterial pcr assay exhibited positive results for 46 clinical isolates from which 43 samples were detected by real time pcr assay. the sensitivity of the assay is about 93.7% in blind test isolates. the pcr results were reconfirmed using the conventional culture method. this assay has the potential to be a rapid, accurate and highly sensitive molecular diagnostic tool for simultaneous detection of escherichia coli, staphylococcus aureus, streptococcus pneumoniae, klebsiella pneumoniae, pseudomonas aeruginosa and acinetobacter spp. this assay has the potential to detect nosocomial pathogens within 5 to 6 hours, helping to initiate infection control measures and appropriate treatment in paediatric and elderly (old aged) patients, pre-and post surgery patients and organ transplant patients and thus reduces their hospitalization duration .
