The Vibrant Soundbridge is a new middle ear implantable hearing device. It was first introduced for adult patients with moderate to severe sensorineural hearing loss. With the innovation of the surgical techniques, its usage had been broadened for children and those patients with conductive and mixed hearing loss. We report first two cases of monoaural Vibrant Soundbridge implantation in Malaysia. They were children with bilateral conductive hearing loss who had failed to benefit from previous hearing aids. Floating mass transducers were attached in oval window and long process of incus respectively. Remarkable hearing yield was observed without surgical complication.
Penetrating injury to the head is considered a form of severe traumatic brain injury. Although uncommon, most neurosurgical centres would have experienced treating patients with such an injury. Despite the presence of well written guidelines for managing these cases, surgical treatment requires an individualized approach tailored to the situation at hand. We describe a collection of three cases of non-missile penetrating head injury which were managed in two main Neurosurgical centres within Malaysia and the unique management approaches for each of these cases.
INTRODUCTION: This study focuses on sexual harassment, a form of psycological hazard that female registered nurses face throughout their day to day routine. The objective of this study is to find the prevalence of sexual harassment among female registered nurses working in government hospitals in Melaka, Malaysia and factors affecting them.
METHODS: This is a cross sectional study conducted on 455 female registered nurses who have worked more than one year in the present 3 government hospitals in Melaka, Malaysia. A validated and pre tested questionnaires were given for the respondents to answer. Before respondents answer the questionaires, they are required to read the definition and the forms of sexual harassment provided. This is to help them to understand the correct definition and forms of sexual harassment that they could have experienced. The researcher is available during the distribution of the questionnaires and the respondents are free to ask the researcher anything that they do not understand about it.
RESULTS: The results of this study show that the prevalence of sexual harassment among these nurses was 51.2% with the past one year incidence recorded at 22.8%. The most common forms of sexual harassment were verbal (46.6% ), visual (24.8% ), psycological (20.9%), physical (20.7%) and non -verbal (16.7% ). The study showed that 74.7% of the victims suffered from psychological effects brought upon by their encounter with various types of sexual harrasement at work. The study also found that the victims' self-perception of their physicality was a contributing factor to the prevalance of this situation. Those who were pretty, with attractive body figure, a friendly character and easy going had a higher prevalence of sexual harassment in the workplace. Meanwhile, those who were strict, and those who had a fierce character were not prone to sexual harassment.
CONCLUSION: The prevalence of sexual harassment among registered nurses in the workplace found in this study was high and self-perception profile of the victims of sexual harassment was the main contributing factor to the problem. Sexual harassment in the workplace should not be taken lightly because the resulting effects was not only felt by the victims, but also by their family members, colleagues and patients under their care. Hence, steps should be taken by the hospital managements to manage and prevent this problem from occuring again in the future.
INTRODUCTION: Several studies have found higher in-hospital mortality for admissions during weekend or off hours, known as "weekend or off-hour effect". However, data for this on Malaysian populations is limited. This study was conducted to analyze the 3-year mortality trend in a secondary hospital and its relation to time and date of admission.
METHODS: The clinical data of 126,627 patients admitted to Taiping Hospital from 1st January 2008 to 31st December 2010 obtained via patient registry database of hospital was analyzed. This study compared mortality during weekdays with weekends, office hours (0800-1700) with off hours (1701-0759), and subanalysis of office hours with evening (1701-2259) or night hours (2300-0759), adjusted for age and gender.
RESULTS: Although the overall staff-to-patient ratio is improving, analyses showed a statistically significant increased risk of mortality for those patients admitted during weekends (OR = 1.22; 95% confidence interval [CI] = 1.14-1.31) or off hours in a weekday (OR = 1.67; 95% CI = 1.57-1.78). In the comparison between time of admission, there was statistically significant increased risk of mortality for admissions during evening hours (OR = 1.44; 95% CI = 1.28-1.62) and night hours (OR = 1.92; 95% CI = 1.71-2.16). Diseases of cardiovascular and respiratory system remained the top two causes of death over the three years.
CONCLUSION: The risk of mortality is significantly higher as a result of "weekend or off-hour effect". Recognition and intervention addressing these issues will have important implications for the healthcare system setting, hospital staffing and training, quality and timeliness of medical care delivery.
This study aimed to estimate cost of in-patient medical care due to stroke in a tertiary hospital in Malaysia. A retrospective analysis of stroke patients admitted to Universiti Kebangsaan Malaysia Medical Centre (UKMMC) between January 2005 and December 2008 were conducted. Cost evaluation was undertaken from the health provider's perspective using a top-down costing approach. Mean length of stay (LOS) was 6.4 ± 3.1 days and mean cost of care per patient per admission was MYR 3,696.40 ± 1,842.17 or 16% of per capita GDP of the country. Human resources made up the highest cost component (MYR 1,343.90, SD: 669.8 or 36% of the total cost), followed by medications (MYR 867.30, SD:432.40) and laboratory services (MYR 337.90, SD:168.40). LOS and cost of care varied across different stroke severity levels (p<0.01). A regression analysis shown significant influence of stroke severity on cost of care, with the most severe stroke consumed MYR 1,598.10 higher cost than the mild stroke (p<0.001). Cost of medical care during hospital admission due to stroke is substantial. Health promotion and primary prevention activities need to take priority to minimise stroke admission in future.
Coolia is a widespread and ecologically important genus of benthic marine dinoflagellates found in tropical regions. Historically, there has been taxonomic confusion about the taxonomy and toxicity of this group. The goal of this study was to resolve morphological questions concerning Coolia tropicalis and determine the taxonomic identity of the Australian Coolia isolate which has been reported to produce cooliatoxins. To accomplish this, the morphology of tropical strains from Belize (the type locality of C. tropicalis), Malaysia, Indonesia, and Australia were examined and compared to published reports. The morphological analysis showed that C. tropicalis differs from the original description in that it has a slightly larger size (35-47 μm long by 30-45 μm wide versus 23-40 μm long by 25-39 μm wide), and the shape of fourth apical plate, and the length of Po plate (7.4-12 μm versus 7 μm). Based on both morphology and phylogenetic analysis using LSU D1- D3 rDNA sequences, the clones of C. tropicalis from Malaysia, Indonesia, and Belize were found to form a monophyletic clade within the genus. The strain producing cooliatoxin was found to be C. tropicalis, not Coolia monotis as originally assumed. To explore the factors influencing the growth of Coolia species, the growth rates of C. tropicalis and Coolia malayensis were determined at different temperatures and salinities. Both species tolerated a wide range of temperatures, but cannot survive at temperatures <20°C or >35°C. C. monotis, the dominant species reported in the literature, probably does not produce toxins.
The potential harms of herbs to the pregnant mothers and their foetuses as well as the effect of herbs taken by nursing mothers on their babies remain largely unknown. Common perception is that herbal medicines ingestion during pregnancy and confinement period is a common practice among multi-racial Malaysian mothers. The purpose of this study was to explore the usage of herbal medicines during pregnancy and post-partum period among mothers who gave birth at a tertiary hospital in a metropolitan city of Malaysia. This cross sectional study was conducted between October and December 2010. The subjects were interviewed twice after giving birth: before hospital discharge and 6 to 8 weeks later. A total of 323 mothers were recruited for this study. The prevalence of herbs ingestion during pregnancy was 13.9%, with half of the users consuming it during the first trimester. A total of 163 (52.9%) mothers ingested herbs during the post-partum period. Significantly more Chinese (p=0.01) and Malay (p=0.04) mothers ingested herbs during pregnancy and post-partum period, respectively. Infants of mothers who ingested herbs had a higher rate of neonatal jaundice compared to infants of mothers who did not ingest herbs during the post-partum period (P=0.001).

The elemental profiles of six honey samples from Malaysia had been constructed using the data obtained from both ICP-AES and ICP-MS. Potassium and sodium were the most abundant minerals covering from 69.3-78.6% and 14.1-28.7%, respectively. The ratio of potassium to sodium was more than one. Even though the minerals and trace elements composition varied dependent on the type of honey samples, there was no statistically significant difference between the analysed honey samples, namely tualang, gelam, acacia and a few forest honeys based on two-factor ANOVA and cluster analysis. The total element content of honey samples were strongly correlated with the electrical conductivity, but only have moderate correlation with the ash content and honey colour based on the regression analysis. PCA result on the available elemental data from worldwide honeys, including honey samples from Malaysia revealed that potassium and sodium were the mineral markers to distinguish honey origin. Both tualang and gelam honey samples from Malaysia have close mineral profile with sesame honeys from Egypt and multifloral honeys from India, whereas forest honeys Malaysia were near to avocado honeys from Spain and multifloral honeys from India.
Knowledge on the population of genetic structure and ecological behaviour of Apis dorsata from Peninsular Malaysia is needed for effective management and conservation of this species since unsustainable whole solitary low nest cutting for product harvesting is the current common practice here. The analysis of 15 single locus DNA microsatellite markers on samples from 20 solitary nests of A. dorsata showed that while these markers were polymorphic, high intracolonial relatedness existed. Furthermore, in general, slightly negative values of intercolony relatedness (R) among the nests of A. dorsata were found. However, positive values of mean intercolony relatedness were observed between 54 pairs of nests out of 190 possible combinations. The R values among nest pairs 3-4 and 3-5 was higher than 0.50 showing that their queens were half siblings, whereas nest pair 19-20 showed relatedness of 0.95 indicating that the same queen was sampled. The results that we obtained could not conclusively support the hypothesis of this study that the honey hunters in Marang district of Malaysia repeatedly harvest the same nest located at a different site and at a different time during the same honey harvesting season. However, our finding of an appreciable level of intercolonial relatedness between several pairs of nests in this pioneer study indicated that a comprehensive study with a larger sample size of solitary nests found throughout the region would be necessary to provide concrete proof for this novel idea.
The study aimed to identify the factors associated with street racing among the illegal motorcycle racers in Malaysia also known as the Mat Rempit, and their help-seeking intention. A total of 2,022 Mat Rempit were surveyed. The findings support the notion that experience-seeking, prestige-seeking, excitement-seeking, self-satisfaction, underestimate risk, and social influence were factors influencing illegal motorcycle street racing. The overall intention to seek help was extremely low. The majority (77.9%) reported that they would solve the problem themselves and 75.5% thought that illegal street racing is not big deal and would go away in time. Participants with neither (OR 0.41; 95% CI 0.27-0.62) or at least one parent who is strict (OR 0.52; 95% 0.37-0.73) were less likely to have high help-seeking intention than those with both parents who are strict. Study indicates a need for family-centered intervention to curb illegal street racing.
Sea-level rise (SLR) due to global warming will result in the loss of many coastal areas. The direct or primary effects due to inundation and erosion from SLR are currently being assessed; however, the indirect or secondary ecological effects, such as changes caused by the displacement of human populations, have not been previously evaluated. We examined the potential ecological consequences of future SLR on >1,200 islands in the Southeast Asian and the Pacific region. Using three SLR scenarios (1, 3, and 6 m elevation, where 1 m approximates most predictions by the end of this century), we assessed the consequences of primary and secondary SLR effects from human displacement on habitat availability and distributions of selected mammal species. We estimate that between 3-32% of the coastal zone of these islands could be lost from primary effects, and consequently 8-52 million people would become SLR refugees. Assuming that inundated urban and intensive agricultural areas will be relocated with an equal area of habitat loss in the hinterland, we project that secondary SLR effects can lead to an equal or even higher percent range loss than primary effects for at least 10-18% of the sample mammals in a moderate range loss scenario and for 22-46% in a maximum range loss scenario. In addition, we found some species to be more vulnerable to secondary than primary effects. Finally, we found high spatial variation in vulnerability: species on islands in Oceania are more vulnerable to primary SLR effects, whereas species on islands in Indo-Malaysia, with potentially 7-48 million SLR refugees, are more vulnerable to secondary effects. Our findings show that primary and secondary SLR effects can have enormous consequences for human inhabitants and island biodiversity, and that both need to be incorporated into ecological risk assessment, conservation, and regional planning.
Two studies examined correlates of belief in a Jewish conspiracy theory among Malays in Malaysia, a culture in which state-directed conspiracism as a means of dealing with perceived external and internal threats is widespread. In Study 1, 368 participants from Kuala Lumpur, Malaysia, completed a novel measure of belief in a Jewish conspiracy theory, along with measures of general conspiracist ideation, and anomie. Initial analysis showed that the novel scale factorially reduced to a single dimension. Further analysis showed that belief in the Jewish conspiracy theory was only significantly associated with general conspiracist ideation, but the strength of the association was weak. In Study 2, 314 participants completed the measure of belief in the Jewish conspiracy theory, along with measures of general conspiracist ideation, and ideological attitudes. Results showed that belief in the Jewish conspiracy theory was associated with anti-Israeli attitudes, modern racism directed at the Chinese, right-wing authoritarianism, and social dominance orientation. General conspiracist ideation did not emerge as a significant predictor once other variables had been accounted for. These results suggest that there may be specific cultural and social psychological forces that drive belief in the Jewish conspiracy theory within the Malaysian context. Specifically, belief in the Jewish conspiracy theory among Malaysian Malays appears to serve ideological needs and as a mask for anti-Chinese sentiment, which may in turn reaffirm their perceived ability to shape socio-political processes.
The performance of 11 oil palm AVROS (Algemene Vereniging van Rubberplanters ter Oostkust van Sumatra) pisiferas was evaluated based on their 40 dura x pisifera (DxP) progenies tested on inland soils, predominantly of Serdang Series. Fresh fruit bunch (FFB) yield of each pisiferas ranged from 121.93 to 143.9 kg palm⁻¹ yr⁻¹ with trial mean of 131.62 kg palm⁻¹ yr⁻¹. Analysis of variance (ANOVA) showed low genetic variability among pisifera parents for most of the characters indicating uniformity of the pisifera population. This was anticipated as the AVROS pisiferas were derived from small population and were inbred materials. However, some of the pisiferas have shown good general combining ability (GCA) for certain important economic traits. Three pisiferas (P1 (0.174/247), P3 (0.174/498), P11 (0.182/308)) were identified of having good GCA for FFB yield while pisiferas P1 (0.174/247), P10 (0.182/348), and P11 (0.182/308) were good combiners for oil-to-bunch ratio (O/B). The narrow genetic base of these materials was the main obstacle in breeding and population improvement. However, efforts have been made to introgress this material with the vast oil palm germplasm collections of MPOB for rectifying the problem.
