Perceived Social Support and Life Satisfaction of Malaysian Chinese Young Adults: The Mediating Effect of Loneliness

Gan SW, Ong LS, Lee CH, Lin YS

J Genet Psychol, 2020 08 13;181(6):458-469.
PMID: 32787705 DOI: 10.1080/00221325.2020.1803196

This paper examined the role of loneliness in mediating the relation between social support and life satisfaction among Chinese young adults within the Malaysian context. Young adults (N = 275; Mage = 22.41; SD = 1.76; 57.5% females) completed self-administered questionnaires on the scales of perceived social support, loneliness and life satisfaction. The results of Structural Equation Modeling (SEM) showed a partial mediation effect of loneliness on the relation between social support and life satisfaction. The integration of the bottom-up theory of subjective well-being and social cognitive theory is included to explain the mediating process. The results revealed that perceived social support can relate to a lower level of loneliness, which could eventually lead to higher levels of young adults' life satisfaction. Overall, the findings highlighted the importance of social support as well as their loneliness as a mediating pathway in promoting Malaysian Chinese young adults' life satisfaction. Interventions are also suggested to optimize life satisfaction as a whole.

Haron K, Shaffie Z, Ghazi HF, Isa ZM

J Interpers Violence, 2021 03;36(5-6):NP2576-NP2600.
PMID: 29624110 DOI: 10.1177/0886260518759059

The objective of this study was to determine the prevalence of men's violence against pregnant women and whether it is influenced by women's attitude. A cross-sectional study was carried out in a hospital in northern state of Peninsular Malaysia. A total of 1,200 postnatal women aged 18 years and above who had been admitted to the hospital were recruited in the study. Universal sampling was performed, and participants were interviewed face-to-face by using a validated Malay version of WHO Women's Health and Life Experiences Questionnaire. The main outcome measures in the study were emotional, physical or sexual violence. The study results showed that more than one third of women (35.9%; confidence interval [CI] = [0.33, 0.39]) had experienced any type of violence during pregnancy with the commonest was psychological violence (29.8%; CI = [0.27, 0.32]) followed by physical (12.9%; CI = [0.11, 0.15]) and sexual violence (9.8%; CI = [0.08, 0.12]). Women who were drug users, had an exposure to violence during childhood, had higher parity, and had inadequate antenatal care were at greater risk. Agree that husband is justified to hit his wife in certain conditions and agree that women has a right to refuse sex in certain conditions were among violence-supporting attitudes. It can be concluded that men's violence against pregnant women is extremely prevalent. Sensitive assessment, attitude modification, and intervention (primary, secondary, and tertiary) are of great value in combating men's violence against pregnant women.

Fulltext A Qualitative Study to Explore the Barriers for Nonadherence to Referral to Hospital Births by Women with High-Risk Pregnancies in Nepal

Rajbanshi S, Norhayati MN, Nik Hazlina NH

Int J Environ Res Public Health, 2021 05 28;18(11).
PMID: 34071394 DOI: 10.3390/ijerph18115801

Maternal and neonatal morbidity and mortality tend to decrease if referral advice during pregnancy is utilized appropriately. This study explores the reasons for nonadherence to referral advice among high-risk pregnant women. A qualitative study was conducted in Morang District, Nepal. A phenomenological inquiry was used. Fourteen participants were interviewed in-depth. High-risk women who did not comply with the referral to have a hospital birth were the study participants. Participants were chosen purposively until data saturation was achieved. The data were generated using thematic analysis. Preference of homebirth, women's diminished autonomy and financial dependence, conditional factors, and sociocultural factors were the four major themes that hindered hospital births. Women used antenatal check-ups to reaffirm normalcy in their current pregnancies to practice homebirth. For newly-wed young women, information barriers such as not knowing where to seek healthcare existed. The poorest segments and marginalized women did not adhere to referral hospital birth advice even when present with high-risk factors in pregnancy. Multiple factors, including socioeconomic and sociocultural factors, affect women's decision to give birth in the referral hospital. Targeted interventions for underprivileged communities and policies to increase facility-based birth rates are recommended.

Alturkustani M, Bahakeem B, Zhang Q, Ang LC

Malays J Pathol, 2020 Aug;42(2):187-194.
PMID: 32860370

INTRODUCTION: Multiple sclerosis (MS) has variable clinical presentations, prognoses, pathogeneses, and pathological patterns. We conducted a pathological review of acute MS-associated lesions that focused on the degree of axonal injury, myelin loss, and glial reaction to determine whether the observed demyelination was of the primary or secondary type.
MATERIALS AND METHODS: After searching the records for a 15-year period at the London Health Sciences Centre Pathology Department, we identified 8 cases of surgical acute lesion biopsies in which clinical MS diagnoses were made before or after the biopsy.
RESULTS: The white matter pathologies in these cases could be sorted into 3 morphological patterns. The first pattern, which represents typical demyelinated plaques, was observed in 4 cases and was characterised by nearly complete demyelination accompanied by variable degrees of axon preservation and axonal swelling. The second pattern was observed in 3 cases and was characterised by demyelinating lesions containing variable numbers of myelinated axons mixed with a few demyelinated axons and variable numbers of axonal swellings. The myelinated axons ranged from scattered fibres to bands of variable thickness, and the demyelination was a mixture of primary and secondary demyelination. The third pattern was observed in 1 case and was characterised by well-demarcated areas of reduced myelin staining and numerous apoptotic nuclei. Axonal staining revealed many fragmented axons with reduced myelin staining but no definitely demyelinated axons.
CONCLUSIONS: This report shows that the predominant pathology underlying acute MS-related lesions is not limited to demyelination but can include axonal degeneration alone or in combination with primary demyelination which reflect different pathogenesis for these acute lesions.

Salim H, Shariff Ghazali S, Lee PY, Cheong AT, Harrun NH, Mohamed Isa S, et al.

BMC Public Health, 2021 06 22;21(1):1186.
PMID: 34158013 DOI: 10.1186/s12889-021-11194-w

BACKGROUND: Limited health literacy among people with asthma is associated with poor adherence to self-management activities, thus poor clinical outcomes. This study aimed to determine the prevalence of health literacy level and its determinants among people with asthma in the Malaysian primary healthcare settings.
METHOD: A cross-sectional study was conducted among participants aged > 18 years with asthma who attended five primary health clinics in Malaysia. Systematic random sampling was employed with a final sample of 550 participants. The questionnaires included the validated Malay version of Health Literacy Scale (HLS) and asthma control questionnaire (ACQ). Statistical analysis was done using SPSS version 25. Multiple logistic regression was performed to determine the determinants for limited health literacy.
RESULTS: The participants mean age of the participants was 48 (SD15.4) years. Most of the participants were women (64%) and of Malay ethnicity (51.1%). Nearly half had a secondary level of education, n = 112, (45.8%). Mean duration of asthma diagnosis is 20.6 (SD 15.9) years. More than half (62.5%) had a family history of asthma. About half (50.9%) had uncontrolled asthma, with 87.3% self-rated themselves as having controlled asthma. About a third (29.1%) received education on of asthma action plan, but only 7.1% of these owned a written version an asthma action plan. Limited health literacy accounts for 60.5% of the participants. The significant determinants for limited health literacy included lower educational attainment (p

Macrorestriction analysis of Streptococcus agalactiae (group B Streptococcus) isolates from Malaysia

Thong KL, Ling GY, Kong LW, Theam LC, Ngeow YF

J Med Microbiol, 2004 Oct;53(Pt 10):991-997.
PMID: 15358821 DOI: 10.1099/jmm.0.05384-0

Streptococcus agalactiae or group B streptococci (GBS) often colonize the gastrointestinal and urogenital tracts of women, who may transmit these organisms to their offspring during the birth process. Using PFGE analysis, the genetic diversity of GBS was studied for strains isolated from pregnant women and their newborn infants in a teaching hospital. A total of 48 different PFGE profiles were obtained from 123 strains, with one profile (S1) appearing to be predominant among both groups studied. There was good overall correlation between the profiles obtained for strains from mother-infant pairs and for strains isolated from different body sites in the same individual. Occasional discrepancies seen in related body sites and among mother-infant pairs suggest concurrent carriage of different strains in the same individual as well as the possibility of an environmental source of organism for the neonate. The overall results demonstrated that many variants of GBS strains occur in Malaysia.

Mohd Saat NZ, Hanawi SA, M F Farah N, Mohd Amin H, Hanafiah H, Shamsulkamar NS

Int J Environ Res Public Health, 2021 06 04;18(11).
PMID: 34200066 DOI: 10.3390/ijerph18116090

Cardiovascular disease is a significant public health concern worldwide, including in Malaysia. Various attempts have been made to resolve this issue. One of the most important methods of controlling cardiovascular risk factors is physical exercise. However, today's women, especially housewives, are often identified by a lack of physical activity. This is alarming to society, as cardiovascular disease can affect the quality of their life. The aim of this study is to determine the relationship between physical activity and cardiovascular risk factors among low-income housewives in Kuala Lumpur. A total of 63 housewives participated in this cross-sectional study. All participating housewives were asked to fill out a sociodemographic questionnaire and the short version of the International Physical Activity Questionnaire (IPAQ). To evaluate cardiovascular risk factors, anthropometric measurements and blood samples were taken. Findings showed that an average of 70.5 ± 232.4 min/week was spent on moderate-to-vigorous physical activity (MVPA), which indicated a low level of physical activity. Data showed that 90.5% of the subjects had low physical activity, 6.3% were moderate, and 3.2% were considered as having a high level of physical activity. For body mass index (BMI), 58.7% of the respondents were obese, 28.6% were overweight (29.10 ± 5.67 kg m-2), and 81.0% of subjects had a waist circumference (WC) value above the normal range (92.74 ± 16.40 cm). A two-way ANOVA test revealed significant mean differences between systolic blood pressure (mm/Hg) and age groups (p > 0.05). Nevertheless, there was a significant association between MVPA and cardiovascular risk factors using negative binomial regression (p < 0.01). The findings of this study highlight the need for health promotional programs to raise awareness, educate, and engage low-income housewives in lifestyle-enhancing behaviors.

Fulltext Co-inhibition of BCL-XL and MCL-1 with selective BCL-2 family inhibitors enhances cytotoxicity of cervical cancer cell lines

Abdul Rahman SF, Muniandy K, Soo YK, Tiew EYH, Tan KX, Bates TE, et al.

Biochem Biophys Rep, 2020 Jul;22:100756.
PMID: 32346617 DOI: 10.1016/j.bbrep.2020.100756

Development of resistance to chemo- and radiotherapy in patients suffering from advanced cervical cancer narrows the therapeutic window for conventional therapies. Previously we reported that a combination of the selective BCL-2 family inhibitors ABT-263 and A-1210477 decreased cell proliferation in C33A, SiHa and CaSki human cervical cancer cell lines. As ABT-263 binds to both BCL-2 and BCL-XL with high affinity, it was unclear whether the synergism of the drug combination was driven either by singly inhibiting BCL-2 or BCL-XL, or inhibition of both. In this present study, we used the BCL-2 selective inhibitor ABT-199 and the BCL-XL selective inhibitor A1331852 to resolve the individual antitumor activities of ABT-263 into BCL-2 and BCL-XL dependent mechanisms. A-1210477 was substituted for the orally bioavailable S63845. Four cervical cancer cell lines were treated with the selective BCL-2 family inhibitors ABT-199, A1331852 and S63845 alone and in combination using 2-dimensional (2D) and 3-dimensional (3D) cell culture models. The SiHa, C33A and CaSki cell lines were resistant to single agent treatment of all three drugs, suggesting that none of the BCL-2 family of proteins mediate survival of the cells in isolation. HeLa cells were resistant to single agent treatment of ABT-199 and A1331852 but were sensitive to S63845 indicating that they depend on MCL-1 for survival. Co-inhibition of BCL-2 and MCL-1 with ABT-199 and S63845, inhibited cell proliferation of all cancer cell lines, except SiHa. However, the effect of the combination was not as pronounced as combination of A1331852 and S63845. Co-inhibition of BCL-XL and MCL-1 with A1331852 and S63845 significantly inhibited cell proliferation of all four cell lines. Similar data were obtained with 3-dimensional spheroid cell culture models generated from two cervical cancer cell lines in vitro. Treatment with a combination of A1331852 and S63845 resulted in inhibition of growth and invasion of the 3D spheroids. Collectively, our data demonstrate that the combination of MCL-1-selective inhibitors with either selective inhibitors of either BCL-XL or BCL-2 may be potentially useful as treatment strategies for the management of cervical cancer.

Loke SR, Sing KW, Teoh GN, Lee HL

Trop Biomed, 2015 Mar;32(1):76-83.
PMID: 25801256 MyJurnal

Space spraying of chemical insecticides is still an important mean of controlling Aedes mosquitoes and dengue transmission. For this purpose, the bioefficacy of space-sprayed chemical insecticide should be evaluated from time to time. A simulation field trial was conducted outdoor in an open field and indoor in unoccupied flat units in Kuala Lumpur, to evaluate the adulticidal and larvicidal effects of Sumithion L-40, a ULV formulation of fenitrothion. A thermal fogger with a discharge rate of 240 ml/min was used to disperse Sumithion L-40 at 3 different dosages (350 ml/ha, 500 ml/ha, 750 ml/ha) against lab-bred larvae and adult female Aedes aegypti and Aedes albopictus. An average of more than 80% adult mortality was achieved for outdoor space spray, and 100% adult mortality for indoor space spray, in all tested dosages. Outdoor larvicidal effect was noted up to 14 days and 7 days at a dosage of 500 and 750 ml/ha for Ae. aegypti and Ae. albopictus, respectively. Indoor larvicidal effect was up to 21 days (500 ml/ha) and 14 days (750 ml/ha), respectively, after spraying with larval mortality > 50% against Ae. aegypti. This study concluded that the effective dosage of Sumithion L-40 thermally applied against adult Ae. aegypti and Ae. albopictus indoor and outdoor is 500 and 750 ml/ha. Based on these dosages, effective indoor spray volume is 0.4 - 0.6 ml/m³. Additional indoor and outdoor larvicidal effect will be observed at these application dosages, in addition to adult mortality.

PMID: 25134893 MyJurnal

The resistance status of riceland Culex vishnui against four major groups of insecticides (i.e., organochlorines, carbamates, organophosphates and pyrethroids) was investigated. Biochemical assays (ESTα, ESTβ, MFO and GST) were also conducted to detect the resistance levels. Throughout a 12-month study period, multiple insecticide resistance was observed in both larvae and adult Cx vishnui. Culex vishnui larvae exhibited low resistance against malathion, temephos and permethrin with resistance ratio (RR) values < 5. In adult bioassay, Cx. vishnui were highly resistant against all tested adulticides with 24h post-treatment mortality < 70%. Correlations between permethrin and malathion resistance, as well as between deltamethrin and cyfluthrin resistance were found in Cx. vishnui. The results indicated that mixed function oxidases activity of Cx. vishnui was the highest compared to ESTα, ESTβ and GST. Spearman rank-order analysis showed that ESTα, ESTβ and GST were involved in multiple resistances in Cx. vishnui. The findings of this study established a baseline of insecticide susceptibility and revealed the effects of agricultural insecticide pressure on the vectors of Japanese encephalitis in Malaysia.

Fulltext The life-cycle of Spirometra species from Peninsular Malaysia

Kavana NJ, Lim L HS, Ambu S

Trop Biomed, 2014 Sep;31(3):487-95.
PMID: 25382475 MyJurnal

The life-cycle of Malaysian Spirometra spp. was studied under experimental conditions in the laboratory. The Cyclops were reared as the first intermediate host, the hamster as the experimental second intermediate host and cat as the definitive host. Maturation and hatching of eggs took 6 to 12 days by incubation at temperature 30 ºC. The hatched coracidium measured 46 x 34 μm. The Cyclops used were susceptible to the coracidial infection. The procercoid older than 5 days in the Cyclop body cavity had minute spines at the anterior end, calcium corpuscles in the body parenchyma and the cercomer at the posterior end. Procercoids 10 to 14 days old were infective to hamster. The plerocercoids from the hamster after 30 days were long and slender and were infective to cats. The plerocercoids experimentally inoculated to cats developed to adult worms and began to produce eggs between 10 to 60 days. Based on the results that have been obtained, a complete life-cycle was successfully elucidated in the laboratory and hamster was identified to be a good laboratory model for a second intermediate host of Spirometra sp.

Isomyia paurogonita Fang & Fan, 1986 (Diptera: Calliphoridae), a rare species of the subfamily Rhiniinae (tribe Cosminini) was recorded for the first time in Malaysia. We collected one male and two females during a field trip conducted at Genting Highland, Pahang, peninsular Malaysia in May 2011. A 3-day old cow liver was offered as attractant and dipterans collected were transferred to the laboratory for specimens processing and identification. The adults of I. paurogonita were attracted to the odour and then captured by using a sweep net. Isomyia paurogonita was also recorded from two other localities in Peninsular and Malaysian Borneo, namely Gombak Utara, Selangor and Sibu, Sarawak.

Fulltext Assessing the susceptibility status of Aedes albopictus on Penang Island using two different assays

Chan HH, Mustafa FF, Zairi J

Trop Biomed, 2011 Aug;28(2):464-70.
PMID: 22041770

Routine surveillance on resistant status of field mosquito populations is important to implement suitable strategies in order to prevent pest outbreaks. WHO test kit bioassay is the most frequent bioassay used to investigate the susceptibility status of field-collected mosquitoes, as it is relatively convenient to be carried out in the field. In contrast, the topical application of active ingredient is less popular in investigating the susceptibility status of mosquitoes. In this study, we accessed the susceptibility status of Aedes albopictus Skuse collected from two dengue hotspots on Penang Island: Sungai Dua and Persiaran Mayang Pasir. Two active ingredients: permethrin and deltamethrin, were used. WHO test kit bioassay showed that both wild strains collected were susceptible to the two active ingredients; while topical application assay showed that they were resistant. This indicated that WHO test kit bioassay less sensitive to low level of resistance compared to topical application assay. Hence, topical application is expected to be more indicative when used in a resistance surveillance programme.

Saadatnia G, Haj Ghani H, Khoo BY, Maimunah A, Rahmah N

Trop Biomed, 2010 Apr;27(1):125-30.
PMID: 20562822

In vitro culture of Toxoplasma gondii can provide tachyzoites which are active, viable and with desirable purity. Thus the aim of this study was to optimize the cell culture method for T. gondii propagation to obtain a consistent source of parasites with maximum yield and viability, but minimum host cell contamination for use in production of excretory-secretory antigen. Tachyzoites with seed counts of 1x10(6), 1x10(7) and 1x10(8) harvested from infected mice were added to VERO cells of different degrees of confluence, namely 50%, 85% and 100%, and examined periodically using an inverted microscope. When the maximum release of the tachyzoites was observed from the host cells, the culture supernatant was removed and the tachyzoites harvested. Using a Neubauer chamber, the percentages of viable tachyzoites and host cell contamination were determined using trypan blue stain. Parameters that gave the best yield and purity of viable tachyzoites were found to be as follows: VERO cells at 85% confluence in DMEM medium and inoculum comprising 1x10(7) tachyzoites. After about 3 days post infection, the tachyzoites multiplied 78x, with a yield of ~7.8x10(8) per flask, 99% viability and 3% host cell contamination. This study has successfully optimized the method of propagation of T. gondii tachyzoites in VERO cells which produce parasites with high yield, purity and viability.

PMID: 20962727

Iranihindia martellata (Senior-White, 1924) is recorded from peninsular Malaysia for the first time. Male and female specimens in the recent collections of forensically important sarcophagid flies were examined and identified based on morphology and DNA sequencing analysis. Male genitalia offer unambiguous species identification characteristics in the traditional taxonomy of flesh flies but the female flies are very similar to one another in general morphology. Female of I. martellata was determined by DNA sequencing (COI and COII) and PCR-RFLP (COI) analysis. Identified females were carefully examined and compared with the morphologically similar species, Liopygia ruficornis (Fabricius, 1794). Female genitalia are re-described and illustrated in this paper.

PMID: 19901906 MyJurnal

Larvae of the Synthesiomyia nudiseta (Wulp) were collected from a decomposed human corpse at the Department of Forensic Medicine, Penang Hospital. A colony of this species was established and the eggs were collected for rearing. The developmental times, rearing temperatures, and relative humidity were recorded twice daily from the time the eggs collected until adult emergence. An average of 5 larvae were randomly collected from the rearings twice daily, warm-water killed and preserved in Kahle's solution. The larval instar stages were determined by observing the number of posterior spiracular slits and the length of the preserved larvae were measured. When the larval life cycle was completed, the accumulated developmental times were calculated. A total of 8 replicates were carried out. The temperature of the rearing room was 28.5+/-1.5 degrees Celcius while the relative humidity was within 67-85%. The total developmental time for S. nudiseta was 322+/-19 hours (13.4+/-0.8 days).
