    Strenuous exercise causes increased production of reactive oxygen species (ROS), creating an imbalance between ROS and antioxidants. The reduced antioxidant defence leads to defective elimination of ROS and consequently, delayed-onset muscle soreness (DOMS). DOMS due to exhaustive or prolonged exercise typically peaks between 24 h and 72 h after exercise results in soreness, inflammation, pain and decreased muscle function. As a result, muscle strength will be reduced progressively and this situation might be detrimental to one's athletic performance, especially amidst competition season. Therefore, supplementation to improve muscle recovery and sports performance has become a common practice among athletes. However, it is suggested to consume natural-based fruit-derived antioxidants as a more effective and safe nutritional strategy. Fruits containing a high amount of polyphenol protect muscle cells from excessive and harmful ROS due to their anti-inflammatory and antioxidant characteristics. To date, there are several expended studies on the consumption of supplements from various antioxidant-rich fruits to provide evidence on their effectiveness, giving better solutions and wider choices of supplementation to the athletes. Therefore, this review aims to provide a comprehensive overview of nutritional standpoint from previous literature on the effect of fruit juices supplementation on muscle recovery and sports performance.

    Globally, heart failure with preserved ejection fraction (HFpEF) is quickly becoming the dominant form of heart failure (HF) in ageing populations. However, there are still multiple gaps and challenges in making a firm diagnosis of HFpEF in many low-to-middle income Asian countries. In response to this unmet need, the Malaysian HFpEF Working Group (MY-HPWG) gathered and reviewed evidence surrounding the use of different diagnostic modalities indicated for patients with HFpEF to identify diagnostic tools that could be conveniently accessed across different healthcare settings. As a result, five recommendation statements were proposed and an accompanying algorithm was developed, with the aim of improving the diagnostic rate of HFpEF. The MY-HPWG recommends using more easily accessible and non-invasive tools, such as natriuretic peptide (NP) biomarkers and basic echocardiogram (ECHO), to ensure timely HFpEF diagnosis in the primary and secondary care settings, and prompt referral to a tertiary care centre for more comprehensive assessments in uncertain cases.

    BACKGROUND: Many published studies in Malaysia have examined and assessed self care among type 2 diabetes mellitus (T2DM) patients using the Summary of Diabetes Self Care Activities (SDSCA) scale. The current paper is a meta-analysis of related studies that also examines how gender and ethnicity influence and shape T2DM self care practices in Malaysia.

    METHODS: We undertook a bibliographic search for studies conducted and published in Malaysia on T2DM adults using the SDSCA scale. This is a two-stage individual participant meta-analysis of SDSCA which synthesised the overall and subscale score based on gender and ethnic groups as well as the correlation between SDSCA and HbA1c.

    RESULTS: We examined 11 studies that utilised SDSCA to analyse 3,720 T2DM patients. The overall SDSCA score was 33.46 (47.8% of the 7-day week). The subscale score for general diet, specific diet, exercise, blood glucose self-monitoring and foot care were 4.80, 4.09, 2.87, 1.80 and 3.21, respectively. A small but statistically significant better self care in some gender or ethnic groups was noted. The SDSCA diet subscale and HbA1c showed statistically significant correlation.

    CONCLUSION: The finding suggested Malaysian T2DM patients were deficient in exercise and blood glucose self-monitoring. In fact, overall self care among Malaysian adult T2DM patients appears to be suboptimal across gender and the three main ethnic groups. Greater efforts are therefore needed to educate Malaysian adult T2DM patients to improve their self care practices.

    BACKGROUND: Head and neck cancer patients usually need nutritional support due to difficulties in swallowing and chewing. Therefore, this study aimed to formulate Musa paradisiaca and Trigona sp. honey jelly (MTJ) as a convenient functional food.

    METHODS: The antioxidant properties were analysed using 2,2'-diphenyl-1 picrylhydrazyl (DPPH), ferric reducing antioxidant potential (FRAP) and 2,2'-azinodi 3-ethylbenthiazolinesulfonate (ABTS) assays. Cytotoxicity was assayed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) test and the induction of apoptosis was observed via caspase-3/7 activity assay. The identification of phenolic compounds was done via ultra-high-performance-liquid chromatography coupled to mass spectrometer (UHPLC-MS/MS).

    RESULTS: The antioxidant analysis exhibited: the half inhibitory concentration (IC50) of DPPH inhibition, 54.10 (SD = 4.51) μg/mL; the FRAP value, 30.07 (SD = 0.93) mM TEQ/100 g; and the ABTS value, 131.79 (SD = 8.73) mg TEQ/100 g. Cinnamic acid was the most abundant phenolic compound, followed by maleic acid and salicylic acid. The IC50 for ORL115 and ORL188 were 35.51 mg/mL and 43.54 mg/mL, respectively. The cells became rounded and dissymmetrical which reduced in number and size. The apoptotic cell death in ORL115 and ORL188 was deduced as caspase-3/7 activities that significantly increased (P < 0.05).

    CONCLUSION: The study evidenced that the antioxidant activity of MTJ could influence the induction of apoptosis in ORL115 and ORL188 in future investigations and verifications.

    The skin has a solid protective system that includes the stratum corneum as the primary barrier and a complete antioxidant defence system to maintain the skin's normal redox homeostasis. The epidermal and dermal cells are continuously exposed to physiological levels of reactive oxygen species (ROS) originating from cellular metabolic activities. Environmental insults, such as ultraviolet (UV) rays and air pollutants, also generate ROS that can contribute to structural damage of the skin. The antioxidant defence system ensures that the ROS level remains within the safe limit. In certain skin disorders, oxidative stress plays an important role, and there is an established interplay between oxidative stress and inflammation in the development of the condition. Lower levels of skin antioxidants indicate that oxidative stress may mediate the pathogenesis of the disorder. Accordingly, the total antioxidant level was also found to be lower in individuals with skin disorders in individuals with normal skin conditions. This review attempts to summarise the skin oxidant sources and antioxidant system. In addition, both skin and total antioxidant status of individuals with psoriasis, acne vulgaris, vitiligo and atopic dermatitis (AD), as well as their associations with the progression of these disorders will be reviewed.

    BACKGROUND: Eating disorders (EDs) are characterised by an abnormal attitude towards food that causes someone to change their eating habits and behaviour. This study aimed to investigate the prevalence of EDs and their associated factors among female going-school adolescents in Jeddah, Saudi Arabia.

    METHODS: A cross-sectional study was conducted in five schools in Jeddah, Saudi Arabia, among a representative random sample of female adolescent students aged 13 years old-18 years old. A simple random sampling method was used to select the participants. An online self-administered questionnaire, the Arabic version of eating attitude test (EAT-26) and socio-cultural attitudes toward appearance questionnaire (SATAQ-4), was used.

    RESULTS: More than half (53.6%) of adolescent girls scored at or above the cut-off point of EAT-26. Around 45% of the participants had experienced family influence on their appearance and body shape, 36.7% had experienced peer influence on these factors, and 49.4% had experienced media influence. Family influence was significantly associated with EDs (P = 0.013).

    CONCLUSION: The high prevalence of EDs among female going-school adolescents in Jeddah, Saudi Arabia, is of great concern. To mitigate this problem, effective programmes must be designed to change their dietary habits while considering the effects of family, peer and media influence, as well as focusing on the importance of eating breakfast and practising physical activity.

    There are controversial debates regarding the effects of contraceptive vaginal ring devices on females' sexual function. Therefore, the meta-analysis of before-after was conducted on the intervention studies published in the past years to clarify these contradictions. The existing literature on the subject was reviewed by searching through such databases as PubMed, Scopus, ISI Web of Sciences, Embase, Cochrane Library and Google Scholar up to July 2021. Before-after intervention studies that had examined the effect of vaginal rings on females' sexual function were collected as well. In total, five studies with 369 participants were included in quantitative syntheses. Pooled results from the random-effect model showed that NuvaRing had a positive effect on females' sexual function three months after insertion (WMD: 2.48; 95% CI: 0.30, 4.67; P = 0.026); however, this effect was not significant after 6 months (WMD: 4.38; 95% CI: -4.95, 13.72; P = 0.357). Meta-regression analysis suggested that the effect of this device is associated with users' age and body mass index 3 months after insertion. No publication bias was found by Egger's test or funnel plots. Overall, the results of this meta-analysis support the view that vaginal ring use is associated with a positive effect on the sexual function of women 3 months after insertion, while the effect of this device on the sexual function of women was insignificant after 6 months. However, given the dearth of available data, it is not possible to reach a definite conclusion on the effect of vaginal rings on females' sexual function.

    BACKGROUND: Concerted efforts have been undertaken to reduce the human immunodeficiency virus (HIV) infection by the year 2030 in Malaysia. A situational analysis of the performance of successful HIV treatment and its determinants is vital; however, this information remains scarce. This study aimed to identify the determinants of undetectable viral load among people living with HIV (PLHIV).

    METHODS: Newly diagnosed HIV cases (n = 493) registered under the Malaysia HIV/AIDS-related national databases from June 2018 to December 2019 were studied. The deterministic matching method was applied to link the records in two national databases (at Kuala Lumpur and Putrajaya Federal Territories Health Department, JKWPKLP HIV line-listing database and National AIDS Registry). Successful HIV treatment, an outcome variable, was measured by the undetectable viral load < 200 copies/mL after 1 year of antiretroviral therapy initiation. Logistic regression analysis was applied in the current study.

    RESULTS: Results showed that 454/493 (92.2%; 95% confidence interval [CI]: 89.8%, 94.6%) PLHIV had successful HIV treatment. Study participants had a mean (SD) age of 30 (8.10) years old, predominantly male (96.1%) and sexually transmission (99.9%). The multiple logistic regression analysis revealed two significant determinants including the timing of ART initiation (AOR = 3.94; 95% CI: 1.32, 11.70; P = 0.014) and establishment of Sexually Transmitted Infection Friendly Clinic (STIFC) (AOR = 3.40; 95% CI: 1.47, 7.85; P = 0.004). Non-significant variables included gender, education level, HIV risk exposure, and co-infections of tuberculosis and Hepatitis C.

    CONCLUSION: JKWPKLP is on the right track to achieving universal treatment as a prevention strategy. Reinforcement of early ART initiation and establishment of STIFC are recommended.

    BACKGROUND: Hypopituitarism following traumatic brain injury (TBI) is not rare however most patients were left undiagnosed and untreated. Association of post TBI hypopituitarism causing neurobehavioural and quality of life impairment. The aim of the study is to determine the incidence of the chronic anterior pituitary deficiency in patients with traumatic brain injury. Subsequently determine the risk factor and the outcome of the patient with chronic anterior pituitary dysfunction.

    METHODS: This is single centre cross-sectional study involved 105 traumatic head injury patients under the Neurosurgical Department Hospital Sultanah Aminah, Johor Bahru, Malaysia. The primary investigator will do an interview and the patients will be asked question to complete a questioner from SF-36 (36 questions). Subsequently, consent for participation will be taken and blood sampling will be done.

    RESULTS: Thirty-three patients were noted to have anterior pituitary dysfunction. The mean age was 36.97 ± 12.96 years old. Twenty-seven patients (32.5%) were male and six patients were female (27.3%). Chronic anterior pituitary dysfunction in patients with a severe traumatic head injury around 47.1% (23 patients), as compared to a moderate head injury (8 patients, 38.1%) and 2 sustained mild head injury (5.6%). The mean duration after the onset of trauma was 10.3 ± 1.79 months. All patient with anterior pituitary dysfunction had positive CT brain findings with 22 had subarachnoid haemorrhage (SAH) at the basal cistern and 27 patients had a base of skull fracture, where 52.1% of the patient underwent surgical intervention, 84.8% involved one axis and another 5 patients had two axes involved. Severity of the head injury (P < 0.001), prolonged duration of hospital stay (P = 0.014), radiological findings of a base of skull fracture (P < 0.001) and presence of SAH at basal cistern (P < 0.001) was significantly associated with pituitary dysfunction. The patient with anterior pituitary dysfunction has the lower 36-item Short Form Survey (SF-36) marks 56.3 ± 10.3.

    CONCLUSION: The prevalence of hypopituitarism was 31%. Indicators are increased TBI severity, prolonged hospitalisation and positive finding in radiological assessment. Post-traumatic chronic anterior pituitary dysfunction also related with poor quality of life as showed by low SF-36 marks.

    BACKGROUND: Adverse childhood experiences (ACEs) are linked with health risk behaviours (HRBs). The study aimed to evaluate ACEs in the undergraduate health campus of a public university located in the northeast of Malaysia and determine their association with HRBs.

    METHODS: A cross-sectional study was performed by recruiting 973 undergraduate students at the health campus of a public university from December 2019 to June 2021. The World Health Organization (WHO) ACE-International Questionnaire and the Youth Risk Behaviour Surveillance System questionnaire were distributed using simple random sampling according to year of study and the selected batch of students. Descriptive statistics were used for demographic findings and logistic regression analyses were performed to determine the association between ACE and HRB.

    RESULTS: The 973 participants (male [n = 245] and female [n = 728]) had a median age of 22 years old. The prevalence of child maltreatment among the study population was 30.2%, 29.2%, 28.7%, 9.1% and 6.1% for emotional abuse, emotional neglect, physical abuse, physical neglect and sexual abuse, respectively, among both sexes. The most commonly reported household dysfunctions were parental divorce/separation (5.5%). Community violence was 39.3% among the surveyed participants. The highest prevalence of HRBs among respondents was 54.5% from physical inactivity. The findings confirmed that those exposed to ACEs were at risk of HRBs and that a higher number of ACEs was associated with a higher number of HRBs.

    CONCLUSION: ACEs were highly prevalent among participating university students, ranging from 2.6%-39.3%. Hence, child maltreatment is an important public health problem in Malaysia.

    BACKGROUND: Haemophilia A is a bleeding disorder caused by inadequate clotting factor VIII (FVIII). There are two main modes of treatment approach in severe haemophilia A patients either with on-demand or prophylaxis therapy with clotting factor FVIII concentrates. In this study, a comparison was made between the bleeding incidence rate of the on-demand and prophylaxis group in severe haemophilia A patients at Ampang Hospital, Malaysia.

    METHODS: A retrospective study involving patients with severe haemophilia was conducted. The patient's self-reported bleeding frequency was retrieved from the patient's treatment folder from January to December 2019.

    RESULTS: Fourteen patients received on-demand therapy, while the other 24 patients received prophylaxis treatment. The total number of joint bleeds in the prophylaxis group was significantly lower compared to the on-demand group (2.79 bleeds versus 21.36 bleeds [P < 0.001]). Furthermore, the total annual usage of FVIII was higher in the prophylaxis group compared to the on-demand group (1,506 IU/kg/year [± 905.98] versus 365.26 IU/kg/year [± 223.90], P = 0.001).

    CONCLUSION: Prophylaxis FVIII therapy is an effective treatment in reducing the frequency of bleeding joints. However, this treatment approach is associated with high cost due to the high consumption of FVIII.

    Neurological examination is an important tool in diagnosing patients with neurological and neurosurgical conditions. As the complexity and knowledge of neurological and neurosurgical conditions increases, we are now required to learn and indoctrinate our peers and students with the correct skills and methods of examination. Emphasis on the correct techniques of testing muscle strength is essential to avoid errors in recording muscle power and in testing specific muscles which may have overlapping functions. The manual muscle testing of muscles of scapula and upper limbs was performed as to mimic a bedside clinical examination and involved an examiner, a patient and a videographer. The manual muscle testing has been performed in rostrocaudal manner starting from the scapula and ending with the thumbs. A reliable and consistent method of manual muscle testing is lacking among students and clinicians. By adhering to the methods delineated in our text and accompanying video, we hope to reduce inter-examiner variability and increase the reliability and validity of this important examination.

    BACKGROUND: The present study aimed to understand the characterisation of human hippocampal astrocyte following hypoxia exposure. Based on the preliminary screening, 15 min was chosen as the time point and the cells were exposed to different oxygen percentages.

    METHODS: The Trypan blue viability assay used to examine cell death. Immunofluorescence assay, glial fibrillary acidic protein (GFAP) was used to portray the morphology of astrocytes. The hypoxia-inducible factor 1 (HIF-1) staining was performed to confirm hypoxia induced cell death and there was a dramatic expression of HIF-1α displayed in exposed astrocyte cells compared to the control. In molecular level, genes were chosen, such as glyceraldehyde 3-phosphate dehydrogenase (GAPDH), GFAP, HIF-1α and B-cell lymphoma 2 (Bcl-2) and ran the reverse transcription-polymerase chain reaction (RT-PCR).

    RESULTS: Microscope revealed a filamentous and clear nucleus appearance in a control whereas the rupture nuclei with no rigid structure of the cell were found in the 3% oxygen. The control and hypoxia cells were also stained with the annexin V-fluorescein isothiocyanate (annexin V-FITC). Fluorescence microscope reveals astrocyte cells after hypoxia showed higher expression of nuclei but not in control. Merging PI and FITC showed the differences of nuclei expression between the control and hypoxia. In the molecular analysis, there were significant changes of GFAP, HIF-1α and Bcl-2 in hypoxia exposed cells when compared to the control group.

    CONCLUSION: Cells that were exposed to hypoxia (3% oxygen for 15 min) clearly showed damage. General view of human hippocampal astrocyte genomic response to hypoxia was obtained.

    BACKGROUND: Abdominal bloating (AB) is a common medical complaint known to diminish patients' quality of life. However, lifestyle and behavioural changes could mitigate its expression and severity. This study sought to explore the health beliefs, intentions and health-promoting behaviours among people with AB in Kelantan, Malaysia.

    METHODS: The theory of planned behaviour (TPB) was employed to explore the factors that influence the management of adults with AB, namely health beliefs and intentions. An interview guide was developed by adapting the TPB and the findings of prior studies concerning the factors associated with AB management. All eligible participants took part in in-depth interviews.

    RESULTS: The mean age of the participants was 32.5 years old (standard deviation [SD] = 14.19 years old) and the majority of participants were female (58.3%). The themes and sub-themes that emerged following the application of the TPB framework represented the qualitative results of this study, which indicated that the health beliefs, intentions and health-promoting behaviours observed among people with AB were closely related.

    CONCLUSION: The findings of this study suggest that the adoption of a healthy lifestyle could be an effective means of improving AB. Thus, it is vital to implement a health education programme that promotes health-related beliefs and intentions in order to trigger health-promoting behaviour among people with AB.

    During the third week of human pregnancy, an embryo transforms from two germinal disc layers of hypoblast and epiblast to three germinal layers of endoderm, mesoderm and ectoderm. Gastrulation is a complex process that includes cellular mobility, morphogenesis and cell signalling, as well as chemical morphogenic gradients, transcription factors and differential gene expression. During gastrulation, many signalling channels coordinate individual cell actions in precise time and location. These channels control cell proliferation, shape, fate and migration to the correct sites. Subsequently, the anteroposterior (AP), dorsoventral (DV) and left-right (LR) body axes are formed before and during gastrulation via these signalling regulation signals. Hence, the anomalies in gastrulation caused by insults to certain molecular pathways manifest as a wide range of body axes-related disorders. This article outlines the formation of body axes during gastrulation and the anomalies as well as the clinical implications.

    BACKGROUND: Individuals with chronic ankle instability (CAI) have poor postural stability, functional limitations and low quality of life. Although nine-square exercise can improve postural control, there is limited evidence demonstrating whether it can function as an alternative CAI rehabilitation programme. This study aimed to determine the effects of nine-square exercise on postural stability and self-reported outcomes in individuals with CAI.

    METHODS: Eighteen male collegiate athletes with CAI participated in either a 6-week nine-square exercise or a control group (n = 9 per group). At baseline and post-intervention, the participants undertook clinical tests to measures dynamic and static postural control, and self-reported outcomes regarding ankle stability and function.

    RESULTS: Within-group differences, the nine-square exercise group experienced improved dynamic postural control (P = 0.004), static postural control (P = 0.001) and self-reported outcomes (P < 0.05). For the control group, only static postural control improved (P = 0.018). Post-intervention, the nine-square exercise group experienced significant improvements in dynamic postural control (P < 0.001), ankle stability (P = 0.002) and functional ability (P < 0.05) relative to the control group.

    CONCLUSION: These findings suggest that the nine-square exercise can offer an alternative rehabilitation programme for improving postural control, self-perceived ankle stability and functional ability in CAI.

    BACKGROUND: To determine the antibiotic resistance pattern, the prevalence of extended-spectrum beta-lactamases (ESBLs) and carbapenem resistance in blood culture isolates of E. coli. Further, we evaluated and compared Carba NP, Modified Carba NP and a kit-based Rapidec Carba NP test to detect carbapenem resistance rapidly.

    METHODS: Twenty-six carbapenem-resistant strains and four susceptible strains were selected. The three methods mentioned above were evaluated as per Clinical Laboratory Standards Institute (CLSI). These tests are based on biochemical detection of the hydrolysis of the beta-lactam ring of a carbapenem-imipenem, followed by the colour change of a pH indicator.

    RESULTS: Carba NP test was positive in 24 out of 26 isolates; the Modified Carba NP and Rapidec Carba NP tests were positive for all the isolates (26/26). All the carbapenemase non-producers (100%, 04/04) were negative.

    CONCLUSION: Modified Carba NP is a more effortless and inexpensive alternative to the Carba NP test, allowing the detection of carbapenemase activity directly from bacterial cultures of Enterobacteriaceae. The test could be used in low-income countries with large reservoirs for carbapenemase producers and can be implemented in any laboratory worldwide.

    BACKGROUND: Children with autism spectrum disorder (ASD) are susceptible to excessive electronic screen media (ESM) use. This study aimed to evaluate the effectiveness of a parent training programme in improving the screen time and social functioning of children with ASD.

    METHODS: This pre-/post-test quasi-experimental study involved parents by providing them with structured education based on the American Academy of Pediatrics (AAP)' screen time recommendations. In total, 259 children with ASD aged 3 years old-12 years old were eligible. Of those children, 26 were excluded due to comorbidities or taking medications. Additionally, 28 parents participated. Children's screen time were recorded, and social behaviour was scored using the Social Responsiveness Scale pre- and post-intervention.

    RESULTS: There were significant reductions in the average daily screen time of children with ASD after their parents attended the training programme (-51.25 min; 95% CI: -78.40, -24.10). In subgroups with reduced screen time, the treatment effect of the intervention was significant in improving the social responsiveness total score (-3.09; 95% CI: -5.96, -0.22), the social communication scale (-3.64; 95% CI: -5.91, -1.36) and the restricted interest and repetitive behaviour (RRB) scale (-5.27; 95% CI: -10.29, -0.25).

    CONCLUSION: Parental training is effective in reducing screen time and improving social functioning in children with ASD.

    BACKGROUND: Random Forest (RF) is a technique that optimises predictive accuracy by fitting an ensemble of trees to stabilise model estimates. The RF techniques were adapted into survival analysis to model the survival of patients with liver disease in order to identify biomarkers that are highly influential in patient prognostics.

    METHODS: The methodology of this study begins by applying the classical Cox proportional hazard (Cox-PH) model and three parametric survival models (exponential, Weibull and lognormal) to the published dataset. The study further applied the supervised learning methods of Tuning Random Survival Forest (TRSF) parameters and the conditional inference Forest (Cforest) to optimally predict patient survival probabilities.

    RESULTS: The efficiency of these models was compared using the Akaike information criteria (AIC) and integrated Brier score (IBS). The results revealed that the Cox-PH model (AIC = 185.7233) outperforms the three classical models. We further analysed these data to observe the functional relationships that exist between the patient survival function and the covariates using TRSF.

    CONCLUSION: The IBS result of the TRFS demonstrated satisfactory performance over other methods. Ultimately, it was observed from the TRSF results that some of the covariates contributed positively and negatively to patient survival prognostics.
