METHODS: The MELoR study recruited community-dwelling adults aged 55 years and over, selected through stratified random sampling from three parliamentary constituencies. The baseline data collected during the first wave was obtained through face-to-face interviews in participants' homes using computer-assisted questionnaires. During their baseline assessments, participants were asked whether they had ever experienced a blackout in their lifetime and if they had experienced a blackout in the preceding 12 months.

RESULTS: Information on blackouts and ethnicity were available for 1530 participants. The weight-adjusted lifetime cumulative incidence of syncope for the overall population aged 55 years and above was 27.7%. The estimated lifetime cumulative incidence according to ethnic groups was 34.6% for Malays, 27.8% for Indians and 23.7% for Chinese. The estimated 12-month incidence of syncope was 6.1% overall, equating to 11.7% for Malays, 8.7 % for Indians and 2.3% for Chinese. Both Malay [odds ratio (OR) 1.46; 95% confidence interval (CI) 1.10-1.95 and OR 3.62, 95% CI 1.96-6.68] and Indian (OR 1.34; 95% CI 1.01-1.80 and OR 3.31, 1.78-6.15) ethnicities were independently associated with lifetime and 12-month cumulative incidence of syncope, respectively, together with falls, dizziness and myocardial infarction.

METHODS: Female Sprague-Dawley rats were allocated into four groups (n = 8) as follows: (i) the Normal Control group (NC), (ii) the BPA-exposed group (PC), (iii) the group concurrently treated with BPA and F. deltoidea (FC) and (iv) the group treated with F. deltoidea alone (F).

RESULTS: After 6 weeks of concurrent treatment with F. deltoidea, uterine abnormalities in the BPA-exposed rats showed a significant improvement. Specifically, the size of stromal cells increased; interstitial spaces between stromal cells expanded; the histology of the glandular epithelium and the myometrium appeared normal and mitotic figures were present. The suppressive effects of BPA on the expression levels of sex steroid receptors (ERα and ERβ) and the immunity gene C3 were significantly normalised by F. deltoidea treatment. The role of F. deltoidea as an antioxidant agent was proven by the significant reduction in malondialdehyde level in BPA-exposed rats. Moreover, in BPA-exposed rats, concurrent treatment with F. deltoidea could normalise the level of the gonadotropin hormone, which could be associated with an increase in the percentage of rats with a normal oestrous cycle.

MATERIAL/METHODS: Fifty female mice, aged 4-6 weeks, were used in this study. Animals were superovulated, cohabitated overnight, and sacrificed. Fallopian tubes were excised and flushed. Embryos at the 2-cell stage were collected and cultured to obtain 4- and 8-cell stages before being cryopreserved using vitrification and slow freezing. Fixed embryos were stained with fluorescence-labelled antibodies against actin and tubulin, as well as DAPI for staining the nucleus. Labelled embryos were scanned using CLSM and images were analyzed with Q-Win software V3.

RESULTS: The fluorescence intensity of both vitrified and slow-frozen embryos was significantly lower for tubulin, actin, and nucleus as compared to non-cryopreserved embryos (p<0.001). Intensities of tubulin, actin, and nucleus in each stage were also decreased in vitrified and slow-frozen groups as compared to non-cryopreserved embryos.

DESIGN: Mixed-methods systematic review (PROSPERO: CRD42018091033).

SETTING AND PARTICIPANTS: Asian adults (≥18 years old) living in the community globally.

METHODS: Medline (Ovid), Web of Science, CINAHL (EBSCO), Open Grey, and Google Scholar were searched from inception to June 30, 2022. Qualitative, quantitative, or mixed-methods studies reporting on the views of non-seriously ill community-dwelling Asian adults on ACP or the factors influencing their ACP uptake were included. Secondary research, studies not published in English, or studies not available as full text were excluded. Two independent teams of researchers extracted data, assessed methodologic quality, and performed the data analysis. Data analysis was conducted using the multistep convergent integrated approach based on Joanna Briggs Institute methodology for mixed-methods systematic review.

RESULTS: Fifty-eight studies were included. Non-seriously ill community-dwelling Asians were willing to engage in ACP (46.5%-84.4%) although their awareness (3.1%-42.9%) and uptake of ACP remained low (14.0%-53.4%). Background factors (sociodemographic factors, and health status, as well as experience and exposure to information) and underlying beliefs (attitude toward ACP, subjective norm, and perceived behavioral control) were found to affect their uptake of ACP. A conceptual framework was developed to facilitate a proper approach to ACP for this population.

METHOD: A survey of all clinicians and nursing staff of the outpatient, casualty and antenatal clinics in University Malaya Medical Centre using a self-administered questionnaire.

RESULTS: Hundred and eight out of 188 available staff participated. Sixty-two percent of the clinicians and 66.9% of the nursing staff perceived the prevalence of domestic violence within their patients to be very rare or rare. Majority of the clinicians (68.9%) reported asking their patients regarding domestic violence 'at times' but 26.2% had never asked at all. Time factor, concern about offending the patient and unsure of how to ask were reported as barriers in asking for domestic violence by 66%, 52.5% and 32.8% of the clinicians respectively. Clinicians have different practices and levels of confidence within the management of domestic violence. Victim-blaming attitude exists in 28% of the clinicians and 51.1% of the nursing staff. Less than a third of the participants reported knowing of any written protocol for domestic violence management. Only 20% of the clinicians and 6.8% of the nursing staff had ever attended any educational program related to domestic violence.

METHODOLOGY: A cross-sectional study with a universal sampling of children and adolescents with special needs aged 2-18 years old, diagnosed with cerebral palsy, down syndrome, autism and attention-deficit/hyperactivity disorder was conducted at Community-Based Rehabilitation in Central Zone Malaysia. Socio-demographic data were obtained from files, and medical reports and anthropometric measurements (body weight, height, humeral length, and mid-upper arm circumference) were collected using standard procedures. Data were analysed using IBM SPSS version 26. The accuracy of the formula was determined by intraclass correlation, prediction at 20% of actual body weight, residual error (RE) and root mean square error (RMSE).

METHODS: The ACPQ was translated according to international guidelines. This validation study was conducted from January to June 2018. Participants who were ≥ 21 years old, and able to understand Malay were recruited from an urban primary care clinic and a tertiary education institution in Malaysia. A researcher administered the ACPQ-M to participants via a face-to-face interview at baseline and 2 weeks later. Each interview took approximately 10-20 min.

RESULTS: A total of 222/232 participants agreed to participate (response rate = 96.0%). Exploratory factor analysis and confirmatory factor analysis found that the ACPQ-M was a 4-factor model. The Cronbach's α values for the four domains ranged from 0.674-0.947. Only 157/222 participants completed the test-retest (response rate = 71%). At test-retest, quadratic weighted kappa values for all domains ranged from 0.340-0.674, except for two domains which ranged from - 0.200-0.467.

DESIGN: This cross-sectional study was conducted from July-September 2018.

SETTING: This study was conducted at the University Malaya Medical Centre, Kuala Lumpur, Malaysia.

PARTICIPANTS: We recruited community-dwelling adults (ambulatory care patients or their accompanying persons) who were ≥21 years old and able to understand English or Malay. A 1:10 systematic sampling procedure was used. Excluded were community-dwelling adults with intellectual disabilities or non-Malaysian accompanying persons. A trained researcher administered the validated English or Malay Advance Care Planning Questionnaire at baseline and 2 weeks later.

PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the KAP regarding ACP. The secondary outcomes were factors associated with KAP.

RESULTS: A total of 385/393 community-dwelling adults agreed to participate (response rate 98%). Only 3.1% of the community-dwelling adults have heard about ACP and 85.7% of them felt that discussion on ACP was necessary after explanation of the term. The desire to maintain their decision-making ability when seriously ill (94.9%) and reducing family burden (91.6%) were the main motivating factors for ACP. In contrast, resorting to fate (86.5%) and perceived healthy condition (77.0%) were the main reasons against ACP. Overall, 84.4% would consider discussing ACP in the future. Community-dwelling adults who were employed were less likely to know about ACP (OR=0.167, 95% CI 0.050 to 0.559, p=0.004) whereas those with comorbidities were more likely to favour ACP (OR=2.460, 95% CI 1.161 to 5.213, p=0.019). No factor was found to be associated with the practice of ACP.

OBJECTIVE: The effects of Brequinar Sodium (BQR) and 4SC-101 on lymphoblastoid cell lines were investigated.

METHODS: DHODH expression and cell proliferation inhibition of lymphoblastoid and lymphoma cell lines were analyzed using Western blot analysis and XTT assay, respectively. JC-1 probe and ATP biochemiluminescence kit were used to evaluate the mitochondrial membrane potential and ATP generation in these cell lines. Furthermore, we explored the cell cycle progression using Muse™ Cell Cycle Kit.

RESULTS: Ramos, SUDHL-1 and RPMI-1788 cells are fast-growing cells with equal expression of DHODH enzyme and sensitivity to DHODH inhibitors that showed that the inhibition of DHODH was not cancer-specific. In ATP depletion assay, the non-cancerous RPMI-1788 cells showed only a minor ATP reduction compared to Ramos and SUDHL-1 (cancer) cells. In the mechanistic impact of DHODH inhibitors on non-cancerous vs cancerous cells, the mitochondrial membrane potential assay revealed that significant depolarization and cytochrome c release occurred with DHODH inhibitors treatment in Ramos but not in the RPMI-1788 cells, indicating a different mechanism of proliferation inhibition in normal cells.
