Preferences and willingness of accepting COVID-19 vaccine booster: Results from a middle-income country

The recent wave of COVID-19 cases has led to the potential need for booster doses. We surveyed 6,294 people and found that 87.6% reported willingness to take a booster dose, with vaccine efficacy rate being the most common reason cited to accept booster dose. Differences in acceptance rates were noted among those working in non-health related sectors, different ethnic groups as well as those who had taken viral vector vaccines.     

Evaluation of a method to determine the natural occurrence of aflatoxins in commercial traditional herbal medicines from Malaysia and Indonesia

Traditional herbal medicines, popularly known as ‘jamu’ and ‘makjun’ in Malaysia and Indonesia, are consumed regularly to promote health. In consideration of their frequent and prolonged consumption, the natural occurrence of aflatoxins (AF) in these products was determined using immunoaffinity column clean-up and high-performance liquid chromatography with pre-column derivatization. The evaluated method, which entails dilution of sample extracts with Tween 20–phosphate buffered saline (1:9, v/v) and a chromatographic system using isocratic mobile phase composed of water–methanol–acetonitrile (70:20:10, v/v/v), was effective in separating AFB₁, AFG₁ and AFG₂ from interference at their retention times. Results were confirmed using post-column derivatization with photochemical reactor. For 23 commercial samples analyzed, mean levels (incidence) of AFB₁, AFB₂ and AFG₁ in positive samples were 0.26 (70%), 0.07 (61%) and 0.10 (30%) μg/kg, respectively; one sample was positive for AFG₂ at a level of 0.03 (4%) μg/kg. In contrast to the high levels of AF in crude herbal drugs and medicinal plants reported previously by other researchers, the low contamination levels reported in this study may be attributed to the higher selectivity to AF of the method applied. Based on the AFB₁ levels and the daily consumption of positive samples, a mean probable daily intake of 0.022 ng/kg body weight was calculated.     

Are Essential Medicines in Malaysia Accessible, Affordable and Available?

Objective: To assess the pharmaceutical sector to know whether people have access to essential medicines. Setting: The study was conducted in 20 public health clinics, five public district drug stores and 20 private retail pharmacies selected randomly in five different areas randomly selected (four states and a federal territory). Method: The methodology used was adopted from the World Health Organization study protocol. The degree of attainment of the strategic pharmaceutical objectives of improved access is measured by a list of tested indicators. Access is measured in terms of the availability and affordability of essential medicines, especially to the poor and in the public sector. The first survey in the public health clinics and public district drug stores gathered information about current availability of essential medicines, prevalence of stock-outs and affordability of treatment (except drug stores). The second survey assessed affordability of treatment in public health clinics and private retail pharmacies. Main Outcome Measure Availability, stock-out duration, percent of medicines dispensed, accessibility and affordability of key medicines. Results The average availability of key medicines in the public health clinics for the country was 95.4%. The average stock-out duration of key medicines was 6.5 days. However, average availability of key medicines in the public district drug stores was 89.2%; with an average stock-out duration of 32.4 days. Medicines prescribed were 100% dispensed to the patients. Average affordability for public health clinics was 1.5 weeks salary and for the private pharmacies, 3.7 weeks salary. Conclusions: The present pharmaceutical situation in the context of essential medicines list implementation reflected that the majority of the population in Malaysia had access to affordable essential medicines. If medicines need to be obtained from the private sector, they are hardly affordable. Although the average availability of essential medicines in Malaysia was high being more than 95.0%, in certain areas in Sabah availability was less than 80.0% and still a problem.     

Distribution of cytokine gene polymorphisms in six Orang Asli subgroups in Peninsular Malaysia

Cytokines are involved in immune responses and the pathogenesis of various diseases. Allelic variations within the genes coding for various ∼30 kDa cytokine protein/glycoproteins have been reported for many populations and have been the subjects of many ancestry and health analyses. In this study, we typed 22 single nucleotide polymorphisms (SNPs) in 13 cytokine genes of 165 Orang Asli individuals by using sequence specific primer-polymerase chain reaction (SSP-PCR) assay. The volunteers came from all across the Peninsular of Malaysia and belong to six Orang Asli subgroups; Batek, Kensiu, Lanoh, Che Wong, Semai and Orang Kanaq. Here we report our general findings and original genotype data and their associated analyses (Hardy–Weinberg proportions, estimation of allele and haplotype frequencies) can be found in the supplementary files and will be held at Allele Frequency Net Database (AFND).     

Impact of gender on sexual problems and perceptions among urban Malay elderly in Malaysia

BackgroundPhysical and pathological changes associated with advancing age affect sexual behaviours of the elderly. The aim of this study was to explore the impact of gender on sexual problems and perceptions among the urban Malay elderly.MethodsA cross-sectional study was conducted among 160 Malaysian elderly participants aged 60 years and older who live in Kuala Lumpur. Twelve neighbourhood associations were randomly selected using multi-stage cluster sampling. Data was collected using standardized and validated questionnaire by face-to-face interview technique with which was conducted by trained interviewers.ResultsMean age of the participants was 65.33 (5.87) year old with majority were still married. Female (55.7%) reported more sexual problems as evidenced by the higher proportion of those with lacked interest in having sex (72.5%), find sex is unpleasant (34.8%) and unable to come to orgasm (55.1%). Gender was found to have significant impact on every model obtained in the analysis for both sexual problems and perceptions. Female elderly were 10.6 times more likely to have sexual problem compared to male elderly (OR = 10.64, P < 0.001, 95% CI 3.61, 31.35) and 033 less likely to have good sexual perception (OR = 0.33, P = 0.027, 95% CI 0.12, 0.88).ConclusionGender is a crucial factor towards sexual problem and perceptions among older persons. Older women were reported to have more sexual problems and poor sexual perceptions, reflecting the needs for sexual awareness and education to improve the perceptions and sexuality in later life.     

Exploring Views on Caregiving for Older Persons among Formal Social Care Workers in Malaysia: A Qualitative Study

The rapid ageing process experienced by many developing countries, lead issues and challenges to deal with the highly demanding social care sector. This qualitative study aimed to explore the understanding and views of the formal caregivers in Malaysia towards social care for older persons. Series of focus group discussions were conducted among 57 institutional social care workers at four public residential care in Peninsular Malaysia based on the identified zones. Two groups of participants involved, those aged less than 40 years old and 40 years old and above, divided based on the mean age. The interview was transcribed verbatim and inductive thematic analysis was conducted to identify the related coding and themes. Three themes were identified to explain the views and understanding of the participants related to social care for older persons namely, religious values, health impact and knowledge. Although many participants emphasized on the negative impact of caregiving for older persons on physical and mental health of the caregivers, they also viewed the job as noble and a useful platform to gain knowledge and enrich their personal experiences related to the later life. Acknowledgement of the negative impacts on health of the carers by the relevant authorities are very important to ensure productivity and quality of work, healthy and safe workplace environment and maintaining the rights of workers.
