Objectives: Sarcopenia has emerged as a significant aging-related disease that affects many facets of societal-level and patient-level public health. This study analysed knowledge of sarcopenia and associated socio-demographic factors among the general public of Malaysia in order to effectively improve its prevention and countermeasures. Methods: A cross-sectional online survey was conducted in Selangor, Malaysia, using Google Forms among 202 Malaysian adults from January 1, 2021 to March 31, 2021. Descriptive statistics were used to analyse the socio-demographic characteristics and knowledge scores. The continuous variables were evaluated using the independent t-test, Mann-Whitney test, and one-way analysis of variance test. The Spearman correlation coefficient was employed to determine the correlation between socio-demographic characteristics and knowledge score levels. Results: The final analysis included 202 participants. The mean±standard deviation age was 49.03±12.65. Only 6.9% of participants had good knowledge of sarcopenia and were aware of sarcopenia's characteristics, consequences, and treatments. Post-hoc comparisons using the Dunnett T3 test showed statistical significance in mean knowledge score and age group (p=0.011) and education level (p≤0.001). The Mann-Whitney test revealed that gender (p=0.026) and current smoking status (p=0.023) significantly influenced knowledge scores. Conclusions: The general public's knowledge of sarcopenia was found to be poor to moderate and associated with age and education status. Therefore, education and interventions by policymakers and healthcare professionals to improve public knowledge of sarcopenia in Malaysia are needed.

In this research, 15 patients were diagnosed with 1.5T and 3.0T MRI instruments (Philips, Medical System, Achieva) to minize Ferromagnetic artifact and find the optimized Tesla. Based on the theory that the 3.0T, when compared to 1.5T, show relatively high signal-to-ratio(SNR), Scan time can be shortened or adjust the image resolution. However, when using the 3.0T MRI instruments, various artifact due to the magnetic field difference can degrade the diagnostic information. For the analysis condition, area of interest is set at the background of the T1, T2 sagittal image followed by evaluation of L3, L4, L5 SNR, length of 3 parts with Ferromagnetic artifact, and Histogram. The validity evaluation was performed by using the independent t test. As a result, for the SNR evaluation, mere difference in value was observed for L3 between 1.5T and 3.0T, while big differences were observed for both L4, and L5(p<0.05). Shorter length was observed for the 1.5T when observing 3 parts with Ferromagnetic artifact, thus we can conclude that 3.0T can provide more information on about peripheral tissue diagnostic information(p<0.05). Finally, 1.5T showed higher counts values for the Histogram evaluation(p<0.05). As a result, when we have compared the 1.5T and 3.0T with SNR, length of Ferromagnetic artifact, Histogram, we believe that using a Low Tesla for Spine MRI test can achieve the optimal image information for patients with disk operation like PLIF, etc. in the past.

Purpose: Glufosinate ammonium (GA; phosphinothricin) can induce neurological complications such as altered mental status, amnesia, and convulsions. This study was conducted to evaluate whether blood lipid profiles can help predict convulsions in patients with GA poisoning. Methods: This study was a retrospective review of data acquired at a tertiary academic university hospital from March 2014 to July 2016. Independent t-test, Mann-Whitney test and Analysis of covariance (ANCOVA) of demographic and laboratory findings of 50 patients with GA poisoning were performed to identify correlations of general characteristics and laboratory findings, including blood lipid profiles of GA-poisoned patients between with and without convulsions. Results: Convulsion as a GA complication showed a significant association with poison volume, age, white blood cell count, and creatine phosphokinase (CK), albumin, lactate dehydrogenase (LDH), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) content in blood according to an independent t-test and Mann-Whitney test. However, ANCOVA demonstrated significant association with LDL and triglyceride. Conclusion: Blood lipid profiles, especially serum LDL and triglyceride, were useful in predicting convulsions in patients with GA poisoning.

Purpose: Although microwave diathermy is widely employed, research conducted in South Korea indicates a lack of theoretical understanding concerning the appropriate application intensity. Consequently, there is a need to enhance the objectivity of microwave diathermy by conducting quantitative studies to determine its effective application intensity and provide suitable application parameters. Methods: The study was performed on 60 participants, divided equally into 40W or 80W microwave diathermy intervention groups. Microwave diathermy was applied at 2,450MHz to iliocostalis and longissimus muscles for 15 minutes in each group. Ranges of motion were compared before and after intervention using straight leg raise (SLR) test results. The analysis was performed using the paired t-test and the independent t-test. Results: SLR angles increased significantly in both groups after intervention, but the 80W group exhibited a greater post-intervention angle increase. While no significant intergroup difference was observed between pre-intervention angles, post-intervention angles were significantly different. Conclusion: The study confirms that microwave diathermy treatment at 40W for 15 minutes effectively increases SLR angles but that treatment at 80W has a greater effect. Further research is warranted to establish quantitatively the optimal time and intensity settings for microwave diathermy.
