This report describes an approach to recover SARS-CoV-2 RNA from rapid antigen test kit (RTK-antigen) cassettes for whole-genome sequencing (WGS). RNA samples were recovered from 33 RTK-antigen cassettes for WGS, with 18 samples achieving more than 80% genome coverage. This work provides a proof-of-concept that positive RTK-antigen cassettes can be safely transported, stored and subjected to WGS, enabling swift identification of circulating variants.

Introduction: Rapid detection of influenza viruses and respiratory syncytial virus (RSV) can be achieved by having rapid molecular point of care tests (POCTs). This expedites the diagnosis attributed by having similar clinical presentations leading to facilitation of precision medicine and reduction of antimicrobial resistance. The growing number of POCTs foster the need to ensure that these POCTs have satisfactory and reliable performance. With that the aim of this study is to evaluate the performance of rapid molecular POCT regarded as ‘X’ for the detection of Influenza viruses and RSV in comparison to multiplex PCR. Methods: A laboratory-based study was conducted from January to December 2020 which involved analysis of 116 nasopharyngeal swabs, tested using POCT X and multiplex PCR as a method of reference. The performance analysis incorporated the sensitivity, specificity, positive and negative predicted values determination. The cycle threshold values were reviewed for discordant results. Results: The POCT X demonstrated sensitivity of 88.57% with 100% specificity for Influenza A virus, and 85.71% of sensitivity with 100% specificity for influenza B virus detection. Meanwhile it revealed 100% sensitivity and specificity for RSV detection. There were ten specimens demonstrating discordant results whereby viruses were not detected by POCT X, however detected by multiplex PCR. The POCT X was not able to detect eight (12.9%) and two (16.7%) influenza A and B viruses respectively. Conclusion: The overall performance of POCT X was corresponded to multiplex PCR. This best served as a steadfast ancillary test for influenza and RSV infection.

Safety culture refers to how safety is addressed and communicated in the workplace. It encompasses the attitudes, beliefs, perceptions, and values of all employees in an organization about safety. A good safety culture can be promoted by management through a commitment to safety, realistic practices for handling hazards, continuous organizational learning and concern for hazards shared across the workforce. The objective of this paper is to reviews the safety culture in handling radioactive sources. The radioactive substances used should comply with the following characteristics where radiotoxicity must be as low as possible, short-living isotopes are preferred to long-living ones and the amounts used must be kept to a minimum. Therefore, the As Low As Reasonably Achievable (ALARA) principle was applied that based on the minimization of radiation doses and limiting the release of radioactive materials into the environment by employing all reasonable methods. Besides that, the ALARA principle is an integral part of all activities that involve the use of radiation or radioactive materials and can help prevent unnecessary exposure as well as overexposure. The three major ALARA principles to assist with maintaining doses are time, distance and shielding. It takes a whole team effort to successfully implement the ALARA in safety culture while doing routine elements of working in handling radioactive materials.

Aims: Piper sarmentosum or locally known as Kaduk, is a tropical herb plant that was investigated for its phenolic content by previous researchers. The present study aimed at the analysis of crude methanolic extract of P. sarmentosum leaves for phenolic compounds identification and its anti-amoebic properties against pathogenic Acanthamoeba castellanii. Methodology and results: Folin-Ciocalteu assay was used to determine P. sarmentosum leaves methanolic extract (PSLME)’s total phenolic content (TPC). The extract was further characterized by using gas chromatography-mass spectrometry (GC-MS), reverse phase-high performance liquid chromatography (RP-HPLC) and liquid chromatography-mass spectrometry (LC-MS) analyses to determine the chemical constituents in methanolic PSLME extract. The cytotoxicity of the extract was evaluated through the determination of inhibition concentration for half of cell population (IC50) of pathogenic A. castellanii followed by cell morphological analysis using inverted light and scanning electron microscopies. Acridine-orange/Propidium iodide (AOPI) staining was also conducted to determine the integrity of cell membrane for quantitative analysis. The results demonstrated that the TPC from PSLME was 142.72 mg [GAE]/g with a total of 33 phenolic compounds identified. The IC50 value obtained for A. castellanii was low (74.64 μg/mL) which indicates promising anti-acanthamoebic activity. Microscopy analyses showed that the plant extract caused cells encystment, in which exhibited by distinctive morphological changes on the cells shape and organelle, as well as shortening of acanthopodia. The dual staining and its quantitative analysis prove compromised membrane integrity in the treated amoeba. Conclusion, significance and impact of study This finding provides the evidence that PSLME contains active phenolic compounds contributing to the anti-acanthamoebic activity on pathogenic Acanthamoeba species.

Behavioural change interventions for weight loss have been found to be effective in the short term, but their long-term effectiveness remains a question. The objective of this study was to evaluate the effectiveness of the 36 weeks F.E.A.T program combining behavioural changes of healthy eating and physical activity. A quasi-experimental study of overweight adults was conducted in Malacca. A total of 53 subjects (mean age 47.4 ± 7.2 years) completed the program in three stages. In the first stage (T1: weeks 1–12), the intervention group (n = 28) participated in the F.E.A.T program activities, while the control group (n = 25) did not receive the intervention. In the second stage (T2: weeks 13-24), the activity was supervised and monitored by the peer support group. Sustainability of activity was measured at the third stage (T3: weeks 25-36). The effectiveness of the program was measured by changes in dietary intake, physical activity score, body weight, body mass index (BMI), waist circumference (WC) and body fat percentage at T0 (pre-intervention), T1, T2 and T3. All parameters showed significant interaction effects (time*group) except for energy intake. The intervention group showed significant decreases from T0 to T3 for energy intake (-14.3%), body weight (-4.3%), BMI (-4.2%), WC (-10.5%) and body fat percentage (-3.6%). While physical activity level increased by 109.6% for the intervention group. There were no significant differences in all of these parameters among the control group. The results show the effectiveness of the F.E.A.T program on dietary status and physical activity changes during the 36-week of intervention period.

Introduction: Low glycemic index (GI) diet is recommended as part of medical nutrition therapy for the management of gestational diabetes mellitus (GDM). While the clinical benefits are evident, data assessing knowledge of the GI concept among women with GDM are scarce. This was a needs assessment study to determine the level of knowledge about the GI concept among women with GDM. Methods: Using a cross-sectional design, we included 85 women with GDM (mean age: 30.6 ± 4.0, pre-pregnancy BMI: 24.8 ± 4.1 kg/m2, gestational age: 34.0 ± 4.0 weeks) from Hospital Serdang, Malaysia. Knowledge about the GI concept was assessed using a developed questionnaire. Additional questions on GDM were assessed using Gestational Diabetes Mellitus Knowledge Questionnaire (GDMKQ). Subjects with less than 50%, 51-74%, and more than 75% total score were categorized as having poor, fair, and good knowledge levels, respectively. Results: The mean knowledge score obtained by the subjects was 12.8 ± 3.5. More subjects scored correctly for GDM-related knowledge (68.2%). More than half (58.8%) had heard about the GI concept previously and 55.3% understood the definition of GI. The average knowledge score about the GI concept was 55.6%; subjects scored highest on the influence of different carbohydrates (teh tarik versus milk) on blood glucose level (87.1%). However, the majority of the subjects had fair knowledge level (62.4%). Conclusion: Women with GDM had moderate knowledge about the GI concept. Results of the needs assessment served as preliminary data for the development of a GI-based nutrition education program in Malaysia.

Introduction: Caregivers and parents are important to the healthy development of children. Therefore, this study was undertaken to assess the knowledge, attitude and oral health practice among caregivers of children with disabilities. Method: A cross-sectional study was conducted among caregivers in three special boarding schools in Kuantan, Pahang, who cared for 7 to 17 years old disabled children using self-administered questionnaires. Kruskal-Wallis and Chi-square test were used to analyse the data. Results: Most caregivers were female (73.2%). The overall mean knowledge score was 87.75%. All of caregivers have agreed that sugary or sticky food and drinks can cause caries and toothbrushing for children is important for oral health. All of the caregivers possess secondary educational level where 75% of the caregivers with tertiary educational level assist the children while brushing teeth. However, 71.9% of caregivers with tertiary educational level and 45% of caregivers with secondary educational level had shown poor oral health practice since they were frequently giving sweet food to the children. Surprisingly, most of the caregivers with secondary educational level (95.2%) and caregivers with tertiary educational level (85%) thought children with disabilities can brush their teeth independently. Conclusion: Despite having adequate oral health knowledge among the caregivers in the special needs boarding schools, their attitude and oral health practice however were not up to the necessary standards. The implementation of oral health promotion related programmes in the special needs boarding schools must be taken into consideration in order to tackle the oral health problems of children with disabilities.

Introduction: High-intensity interval training (HIIT) has been found to improve cardiometabolic health outcome as compared to moderate-intensity continuous exercise. However, there is still limited data on the benefits of HIIT on the expression of regulatory proteins that are linked to skeletal muscle metabolism and insulin sensitivity in obese adults. This study investigated the effects of HIIT intervention on expressions of peroxisome proliferatoractivated receptor-γ coactivator 1-α (PGC-1α) and adiponectin receptor-1 (AdipoR1), insulin sensitivity (HOMAIR index), and body composition in overweight/obese individuals. Methods: Fifty overweight/obese individuals aged 22-29 years were assigned to either no-exercise control (n=25) or HIIT (n=25) group. The HIIT group underwent a 12-week intervention, three days/week, with intensity of 65-80% of age-based maximum heart rate. Anthropometric measurements, homeostatic model of insulin resistance (HOMA-IR) and gene expression analysis were conducted at baseline and post intervention. Results: Significant time-by-group interactions (p<0.001) were found for body weight, BMI, waist circumference and body fat percentage. The HIIT group had lower body weight (2.3%, p<0.001), BMI (2.7%, p<0.001), waist circumference (2.4%, p<0.001) and body fat percentage (4.3%, p<0.001) post intervention. Compared to baseline, expressions of PGC-1α and AdipoR1 were increased by approximately three-fold (p=0.019) and two-fold (p=0.003) respectively, along with improved insulin sensitivity (33%, p=0.019) in the HIIT group. Conclusion: Findings suggest that HIIT possibly improved insulin sensitivity through modulation of PGC-1α and AdipoR1. This study also showed that improved metabolic responses can occur despite modest reduction in body weight in overweight/obese individuals undergoing HIIT intervention.

Walking 10,000 steps daily is associated with beneficial health outcomes. Recent systematic reviews have suggested that pedometers may be an effective motivational tool to promote walking. The aim of this study was to study the effectiveness of a 10-week, pedometer-based walking intervention to improve physical activity, body composition and metabolic health indices in a sample of suburban community-dwelling adults not meeting current physical activity recommendations. After screening, 34 overweight/obese individuals (mean age: 46 ± 8 years, mean BMI: 28.3 ± 4.2 kg/m2 ) were accepted into the walking program conducted by the Health Promotion Community Centre, Bangi. Subjects were instructed to increase their steps by 3000 steps daily above their baseline values for 10 weeks. Daily step count, body weight, BMI, waist circumference, as well as blood pressure, fasting glucose and lipids were evaluated at baseline and following the 10-week intervention. Thirty-one participants completed the program with 100% adherence. The average daily steps recorded during the 10-week intervention was 9693 ± 2196 steps per day. Mean daily steps increased from 8679 ± 2567 steps in Week 1 to 10,766 ± 3200 steps in Week 10 (p=0.040). Overall, there were reductions in body weight (-1.13%, p=0.010), waist circumference (-3.5%, p=0.001) and BMI (-1.41%, p=0.008) as well as fasting blood glucose (-8.5%, p=0.003) and systolic blood pressure (-4.8%, p=0.007) following the intervention. The findings of this study demonstrated that a goal-driven, pedometer-based walking intervention for 10 weeks resulted in a modest reduction in body weight and improved metabolic health outcomes in overweight/obese, community-dwelling adults.

Ficus deltoidea or ‘mas cotek,’ is a uterotonic herb traditionally consumed by women to improve menstrual circulation,assist labour, remove retained placenta and treat postpartum bleeding. The aim of the study was to elucidate the mechanismof F. deltoidea in uterine contraction. Crude extracts from 2 different variants of F. deltoidea were used in the study; F.deltoidea var. Deltoidea (FDD) and F. deltoidea var. Angustifolia (FDA). This study was conducted ex vivo on the strips ofisolated rats uterus treated with either FDD or FDA aqueous extract with increasing concentrations ranging from 10 µg/ml until 1280 µg/ml at time intervals of 5 minutes between doses. The frequency and intensity of the uterine contractionswere monitored via Powerlab software. Maximum contractions for both extracts were identified, recorded and the uterinestrips samples at maximum contraction were selected and homogenized in order determine the role of prostaglandinF2α (PGF2α) in the mechanism of uterine contraction. Other than that, phosphorylated 42/44 (p42/44) of mitogenactivated protein kinase (MAPK) expression was also detected via immunoblotting. The results showed that the maximumcontraction induced by FDD was at the concentration of 320 µg/ml, whereas for FDA was at 960 µg/ml. Both FDD andFDA increased the intensity of uterine strips contractions and there were notable trend of increased PGF2α expression aswell. Further analysis revealed that the uterine contractions involved the MAPK pathway through the phosphorylation ofp42/44 protein. In conclusion, Ficus deltoidea of both variants have the ability to stimulate uterine contraction throughthe mechanism of MAPK pathway.
