Effects of brain breaks video intervention of decisional balance among malaysians with type 2 diabetes mellitus: A randomised controlled trial

Copyright: © 2021 by the authors. Brain Breaks® are structured physical activity (PA) web-based videos designed to promote an interest in learning and health promotion. The objective of this study was to examine its effects on decision balance (DB) which consists of the perceived benefits (Pros) and perceived barriers (Cons) of exercise in people with type 2 diabetes mellitus (T2DM). A randomised controlled trial was conducted among people with T2DM at Hospital Universiti Sains Malaysia. The intervention group received Brain Breaks videos for a period of four months. The intervention and control groups completed the validated Malay version of DB questionnaire for five times, at pre-intervention, the first month, the second month, the third month, and post-intervention. Multivariate Repeated Measures Analysis of Variance was performed for data analysis. A total of 70 participants were included (male = 39; female = 31) with a mean age of 57.6 years (SD = 8.5). The intervention group showed a significant change in the Pros and Cons factors of DB scores over time. The intervention group showed significantly higher scores for the Pros (p-value < 0.001) and lower scores for the Cons (p-value = 0.008) factors than the control group. In conclusion, the Brain Breaks video is an effective intervention to improve decisional balance in patients with T2DM to help them in deciding on behaviour change to be more physically active.Ministry of Higher Education Malaysia for Fundamental Research Grant Scheme (FRGS) with Project Code: FRGS/1/2020/SKK06/USM/03/1

Effects of brain breaks videos on the motives for the physical activity of Malaysians with type-2 diabetes mellitus

Brain Breaks videos are web-based structured physical activity (PA) videos that aim at stimulating an interest in learning and promoting health. Exercise is one of the important treatment regimens for people with type 2 diabetes mellitus (T2DM). Thus, the objective of this study was to determine the effects that Brain Breaks videos have on the motives for PA, as measured by the Physical Activity and Leisure Motivation Scale-Malay (PALMS-M), and the amount of PA, as measured by the International Physical Activity Questionnaire-Malay (IPAQ-M), in T2DM patients (the most common type of diabetes mellitus patients). This study was conducted using a randomized, double-blind design and grouped subjects under two research conditions: an experimental group given Brain Breaks videos and a control group. Purposive sampling was employed to recruit 70 T2DM patients (male = 39, female = 31) with the mean age of 57.6 (SD = 8.5) from Hospital Universiti Sains Malaysia, Kelantan. Over a four-month period, the participants in the experimental group were asked to perform PA daily based on a Brain Breaks video (10 min in duration) that was shared through a WhatsApp group. All participants from both groups answered the PALMS-M questionnaire five times: pre-intervention, the end of the first month, second month, and third month, and post-intervention. A repeated measure multivariate analysis of variance and a repeated measure analysis of variance were performed for the analyses of the data. The results demonstrated that four (appearance, others’ expectations, physical condition, and mastery) out of eight motives for PA produced a significant mean score difference between the two study groups. All eight motives for PA showed an upward trend for the experimental group during the study period, while the control group showed a downward trend for all motives during the study period. As for the amount of PA, both groups showed significant differences (p = 0.001). The amount of PA increased in the experimental group during the study period, while it decreased in the control group. Therefore, Brain Breaks videos can be considered as an effective intervention for motivating T2DM patients for PA and improving their amount of PA

Changes in the total leukocyte and platelet counts in Papuan and non Papuan adults from northeast Papua infected with acute Plasmodium vivax or uncomplicated Plasmodium falciparum malaria

<p>Abstract</p> <p>Background</p> <p>There are limited data on the evolution of the leukocyte and platelet counts in malaria patients.</p> <p>Methods</p> <p>In a clinical trial of chloroquine vs. chloroquine plus doxycycline vs. doxycycline alone against <it>Plasmodium vivax </it>(n = 64) or <it>Plasmodium falciparum </it>(n = 98) malaria, the total white cell (WCC) and platelet (PLT) counts were measured on Days 0, 3, 7 and 28 in 57 indigenous Papuans with life long malaria exposure and 105 non Papuan immigrants from other parts of Indonesia with limited malaria exposure.</p> <p>Results</p> <p>The mean Day 0 WCC (n = 152) was 6.492 (range 2.1–13.4) × 10⁹/L and was significantly lower in the Papuans compared to the non Papuans: 5.77 × 10⁹/L vs. 6.86 × 10⁹/L, difference = -1.09 [(95% CI -0.42 to -1.79 × 10⁹/L), P = 0.0018]. 14 (9.2%) and 9 (5.9%) patients had leukopaenia (<4.0 × 10⁹/L) and leukocytosis (>10.0 × 10⁹/L), respectively. By Day 28, the mean WCC increased significantly (P = 0.0003) from 6.37 to 7.47 × 10⁹/L (73 paired values) and was similar between the two groups. Ethnicity was the only WCC explanatory factor and only on Day 0.</p> <p>The mean Day 0 platelet count (n = 151) was 113.0 (range 8.0–313.0) × 10⁹/L and rose significantly to 186.308 × 10⁹/L by Day 28 (P < 0.0001). There was a corresponding fall in patient proportions with thrombocytopaenia (<150 × 10⁹/L): 119/151 (78.81%) vs. 16/73 (21.92%, P < 0.00001). Papuan and non Papuan mean platelet counts were similar at all time points. Only malaria species on Day 0 was a significant platelet count explanatory factor. The mean D0 platelet counts were significantly lower (P = 0.025) in vivax (102.022 × 10⁹/L) vs. falciparum (122.125 × 10⁹/L) patients.</p> <p>Conclusion</p> <p>Changes in leukocytes and platelets were consistent with other malaria studies. The Papuan non Papuan difference in the mean Day 0 WCC was small but might be related to the difference in malaria exposure.</p

Evaluation of real-time PCR for quantitative detection of Escherichia coli in beach water

The current investigation evaluated the use of real-time polymerase chain reaction (PCR) for quantitative detection of Escherichia coli in marine beach water. Densities of E. coli in 263 beach water samples collected from 13 bathing beaches in Hong Kong between November 2008 and December 2009 were determined using both real-time PCR and culture-based methods. Regression analysis showed that these two methods had a significant positive linear relationship with a correlation coefficient (r) of 0.64. Serial dilution of spiked samples indicated that the real-time PCR had a limit of quantification of 25 E. coli colonies in 100 mL water sample. This study showed that the rapid real-time PCR has potential to complement the traditional culture method of assessing fecal pollution in marine beach water
