Objective: To determine the etiologies of tropical acute febrile illness(TAFI) in West Pahang, Malaysia and to investigate morbidity and mortality factors in relation to TAFI. Methods: A multicenter prospective cohort study was conducted between January and June 2016 in six district hospitals throughout the western part of Pahang State in Peninsular Malaysia. A total of 336 patients answered a standardized questionnaire and blood samples were collected for laboratory confirmation of infectious etiology. Descriptive analysis and logistic regression were performed to identify factors associated with TAFI. Results: A total of 336 patients were included. The patients were mainly Malays(70.2%), males(61.3%), aged(44.6±17.4) years, with more than half(58.9%) presenting with gastrointestinal symptoms. The majority were diagnosed with dengue(35.7%) while malaria(4.5%) was the least frequent. The in-hospital mortality due to TAFI was 9.2%. Patients with meliodosis had five times higher mortality [Adjusted OR: 5.002, 95% CI:(1.233, 20.286)]. Patients with comorbidities such as cardiovascular symptoms(P<0.001) and renal replacement therapy initiation(P<0.001) were significantly associated with in-hospital mortality in all TAFI. Conclusions: The etiology of TAFI in the western Pahang includes dengue, leptospirosis, malaria and melioidosis, which carry the highest risk of in-hospital mortality. The presence of cardiovascular symptoms may be used to assess the disease severity in TAFI, but more studies are needed in the future.

Introduction: Currently, own individual perception is recognized as one of the important factors in the prevention of disease, including coronavirus disease, COVID-19. Given the massive impact of COVID-19 on all population’s life, including nurses as one of the main health services providers in the country, this study aims to translate and validate the Malay Version 5-Items Brief Illness Perception Questionnaire, BIP-Q5 towards COVID-19 among Malaysian nurses. Materials and Methods: Forward and backward translations and pretesting of the BIP-Q5 to Malay were conducted among nurses, subject matter experts, and language professionals. The validations process was elicited through an online cross-sectional study involving 56 nurses based on a ~10:1 subject-to-items ratio sample size estimations. Results: The principal component analysis (PCA) revealed one best component with eigenvalues more than one, confirming the questionnaire’s original version. There are five items within the single component, and all are with weightage of over 43%. The scree plot supported the findings, which showed that at least one factors are suitable to be retained. The overall Cronbach’s α coefficient was 0.7 and the intraclass correlation coefficient was 0.659. The Kaiser-Meyer-Olkin was 0.655, and Bartlett’s test of sphericity p-value was Conclusion: This study showed that the translated Malay Version 5-Items Brief Illness Perception Questionnaire, BIP-Q5 has a good psychometric property, and is a valid and reliable tool to be used to measure illness perceptions towards COVID-19 among Malaysian nurses.

An image retrieval system was developed purposely to provide an efficient tool for a set of images from a collection of images in the large database that matches the user’s requirements in similarity evaluations such as image content similarity, edge, and colour similarity. Retrieving images based on the contents which are colour, texture, and shape is called content-based image retrieval (CBIR). This paper discusses and describes about the colour features technique for image retrieval systems. Several colour features technique and algorithms produced by the previous researcher are used to calculate the similarity between extracted features. This paper also describes about the specific technique about the colour basis features and combined features (hybrid techniques) between colour and shape features.

This study constructs downscaling statistical model in analyzing the hydrological modeling in the study area which faces the risk of flood occurrence as the impact of climate change. The combination of chemometric method and time series analysis in this study show that even during the monsoon season, rainfall and stream flow are not the major contribution towards the changing of water level in the study area. Based on Correlation Test, it shows that suspended solid and water level show high correlation with p-value < 0.05. Factor Analysis being carried out to determine the major contribution to the changes of Water Level and the result show that Suspended Solid shows a strong factor pattern with value 0.829. Based on Control Chat Builder for time series analysis, the Upper Control Limit for water level and suspended solid are 7.529 m and 1947.049 tons/day and the Lower Control Limit are 6.678 m and 178.135 tons/day. This shows that human development in the area gives high impact towards climate change and risk of flood in the study area which commonly faces flood during monsoon season.

This work describes a study of tabletting of selected Malaysian herbs such as Eurycoma longifolia Jack, Ficus deltoidea and Morinda citrifolia. These herbs are famous for their therapeutic properties and are used as herbal medicine or as medicinal food. A cylindrical uniaxial die of 13 mm was used to compress the herb powders into tablets. Pressures ranging from 7.5 MPa to 75 MPa were applied using a universal testing machine. Two feed weights, 0.5 g and 1.0 g, were used to produce the tablets. A binder, the microcrystalline cellulose known as Avicel, was used to investigate its effect on tabletting. Properties associated with both the binder and the compounds were studied, and binary mixtures with compositions ranging from 10% to 60% were examined. The strength of the herb tablets was then tested using an indirect tensile strength test. Upon compression, the Morinda citrifolia powder showed the highest density compared to that of Avicel. However, due to its high elasticity, the tensile strength of the Morinda citrifolia tablet was the lowest. The experimental data were also verified using an established model for compression property development. The results indicated that this simple approach can be used to understand the tabletting characteristics of these herbs.

Malaria control programme utilizing indoor residual spraying of chemical insecticide is only effective if a high coverage of targeted area is achieved. The effectiveness of the residual spraying, on the other hand, relies on the efficacy and residual activity of the insecticides applied, which to a certain extent are influenced by the nature of the sprayed surfaces. The bioefficacy of indoor residual-sprayed deltamethrin wettable granule (WG) formulation for the control of malaria was compared with the current dose of deltamethrin wettable powder (WP) in malaria endemic areas in Balai Ringin, Sarawak. Doses of 20 mg/m2 WP (control), 20 mg/m2 WG, 30 mg/m2 WG and 40 mg/m2 WG were sprayed separately on different surfaces namely, wooden, rough-bamboo, smooth-bamboo and brick surfaces. Residual activity of WP and WG formulations was tested against lab-bred Anopheles maculatus using WHO standard procedure. Deltamethrin at 30 mg/m2 WG exhibited the highest sustainable level of effectiveness against An. maculatus (An. maculatus mortality was between 95% - 100%) up to week 60 post-spraying when sprayed on smooth- bamboo surface. These results indicated that 30 mg/m2 WG could be an ideal concentration for controlling malaria vector effectively up to 15 months of which long-lasting residual spraying was envisaged. The usual two spraying cycles per year with 20 mg/m2 deltamethrin WP could be replaced with 30 mg/m2 deltamethrin WG since the long residual activity was achieved by employing a single spraying only.
