AIMS OF STUDY: To demonstrate Marantodes pumilum leaves aqueous extract (MPE) has an effect on uterine contraction after delivery and to elucidate the molecular mechanisms involved.
METHODS: Day-1 post-delivery female rats were given MPE (100, 250 and 500 mg/kg/day) orally for seven consecutive days. A day after the last treatment (day-8), rats were sacrificed and uteri were harvested and subjected for ex-vivo contraction study using organ bath followed by protein expression and distribution study by Western blotting and immunohistochemistry techniques, respectively. The proteins of interest include calmodulin-CaM, myosin light chain kinase-MLCK, sarcoplasmic reticulum Ca2+-ATPase (SERCA), G-protein α and β (Gα and Gβ), inositol-triphosphate 3-kinase (IP3K), oxytocin receptor-OTR, prostaglandin (PGF)2α receptor-PGFR, muscarinic receptor-MAChR and estrogen receptor (ER) isoforms α and β. Levels of estradiol and progesterone in serum were determined by enzyme-linked immunoassay (ELISA).
RESULTS: Ex-vivo contraction study revealed the force of uterine contraction increased with increasing doses of MPE. In addition, expression of CaM, MLCK, SERCA, Gα, Gβ, IP3K, OTR, PGF2α, MAChR, Erα and ERβ in the uterus increased with increasing doses of MPE. Serum analysis indicate that estradiol levels decreased while progesterone levels remained low at day-8 post-partum in rats receiving 250 and 500 mg/kg/day MPE.
CONCLUSIONS: These findings support the claims that MPE help to firm the uterus and pave the way for its use as a uterotonic agent after delivery.
METHODS: A total of 28 critically ill patients were included in this study. All data were collected from medical, microbiology and pharmacokinetic records. The clinical response was evaluated on the basis of clinical and microbiological parameters. The 24-h area under the curve (AUC0-24) was estimated from a single trough level using established equations.
RESULTS: Out of the 28 patients, 46% were classified as responders to vancomycin treatment. The trough vancomycin concentration did not differ between the responders and non-responders (15.02 ± 6.16 and 14.83 ± 4.80 μg mL-1; P = 0.929). High vancomycin minimum inhibitory concentration (MIC) was observed among the non-responders (P = 0.007). The ratio between vancomycin trough concentration and vancomycin MIC was significantly lower in the non-responder group (8.76 ± 3.43 vs. 12.29 ± 4.85 μg mL-1; P = 0.034). The mean ratio of estimated AUC0-24 and vancomycin MIC was 313.78 ± 117.17 μg h mL-1 in the non-responder group and 464.44 ± 139.06 μg h mL-1 in the responder group (P = 0.004). AUC0-24/MIC of ≥ 400 μg h mL-1 was documented for 77% of the responders and 27% of the non-responders (c2 = 7.03; P = 0.008).
CONCLUSIONS: Ratio of trough concentration/MIC and AUC0-24/MIC of vancomycin are better predictors for MRSA treatment outcomes than trough vancomycin concentration or AUC0-24 alone. The single trough-based estimated AUC may be sufficient for the monitoring of treatment response with vancomycin.
Methods: A total of 380 women who had used the same contraceptive method for at least twelve months were recruited in this study. Covariance analysis was done to compare the weight gain between hormonal and non-hormonal contraceptive users, while studying the same confounders [age, household income, number of pregnancies, and baseline body mass index (BMI)].
Results: Hormonal methods were more commonly used. The mean weight gain among hormonal users (adjusted mean 2.85, 95% CI 2.45, 3.24) was significantly higher than non-hormonal users (adjusted mean 0.46, 95% CI -0.73, 1.65; p-value <0.001), after controlling for age, household income, number of pregnancies, and baseline BMI.
Conclusion: The possibility of weight gain following the use of hormonal methods should be investigated and non-hormonal methods should be considered to prevent weight gain.
Methods: A total of 330 pregnant women visiting the antenatal clinic in Hospital Universiti Sains Malaysia (USM) were surveyed. Data were collected through a self-administered questionnaire and analysed with SPSS software version 22.0.
Results: Overall, 84.5% (n = 279) of the pregnant women had experienced UI. Multiple logistic regression identified body mass index (BMI), presence of other illness, and consumption of coffee as major risk factors for UI. The majority of pregnant women preferred early screening for UI.
Conclusion: A great majority of pregnant women in this study experienced UI. Higher BMI and the presence of other medical conditions are significant risk factors for UI and early screening is required. The need for universal education about UI and pelvic floor muscle exercise is warranted and can potentially prevent postnatal UI and UI later in life.
METHODS: A cross-sectional study was conducted among undergraduate medical students of the School of Medical Sciences of USM. The proposed USM Medical Students' Guidance and Counselling Needs (USM-MSGCN) questionnaire is a self-administered instrument that consists of 68 initial items developed from the recommendation of medical students, counsellors, and lecturers in the medical education department. To determine the dimensionality (construct validity) and reliability of the questionnaire, exploratory factor analysis and Cronbach's alpha internal consistency reliability analysis were conducted.
RESULTS: A total of 208 students participated in the study. Factor analysis revealed that the items were not unidimensional; four potential constructs could be extracted from the questionnaire, namely, self-leadership (7 items), communication (5 items), learning (5 items), and psychological coping skills (3 items), with factor loading ranges of 0.56-0.82, 0.56-0.88, 0.65-0.84, and 0.79-0.80, respectively. These domains had the following internal consistency reliability (Cronbach's alpha): 0.89, 0.90, 0.87, and 0.87, respectively; the overall alpha value was 0.93.
CONCLUSION: Four factors, with 20 items in the USM-MSGCN questionnaire had good validity and reliability values when administered among the pre-clinical medical students.
Methods: A literature search was carried out through Scopus, Science Direct, Google Scholar, PubMed, and EBSCOhost databases based on specific search terms. Each article was appraised based on title, abstract, and full text. The selected articles were critically appraised, and relevant information to support the validity of MMI in various educational settings was synthesized. This paper followed the PRISMA guideline to ensure consistency in reporting systematic review results.
Results: A majority of the studies were from Canada, with 41.54%, followed by the United Kingdom (25.39%), the United States (13.85%), and Australia (9.23%). The rest (9.24%) were from Germany, Ireland, the United Arab Emirates, Japan, Pakistan, Taiwan, and Malaysia. Moreover, most MMI stations ranged from seven to 12 with a duration of 10 min per station (including a 2-min gap between stations).
Conclusion: The results suggest that the content, response process, and internal structure of MMI were well supported by evidence; however, the relation and consequences of MMI to important outcome variables were inconsistently supported. The evidence shows that MMI is a non-biased, practical, feasible, reliable, and content-valid admission tool. However, further research on its impact on non-cognitive outcomes is required.
METHODS: This cross-sectional study was performed in two Malaysian health clinics by using the Malay version of a self-administered questionnaire. This instrument contains a diabetes care profile, a 21-item version of the Depression Anxiety Stress Scales (DASS21), and a Malaysian Medication Adherence Score (MalMAS). Simple and multiple logistic regression analyses were performed.
RESULTS: A total of 338 type II diabetes mellitus patients responded (response rate 93.1%). The proportion of patients with poor glycaemic control was 76.0%. Multiple logistic regression analysis showed that 1) social support scores [Adj. OR (95% CI): 1.06 (1.03,1.10); p = 0.001]; 2) unemployment [Adj. OR (95% CI): 0.46 (0.22,0.95); p = 0.035]; 3) pensioner status [Adj. OR (95% CI): 0.28 (0.13,0.61); p = 0.001]; and 4) perception of diabetes as interfering with daily living activities [Adj. OR (95% CI): 3.18 (1.17,8.70); p = 0.024] were significant factors for poor glycaemic control.
CONCLUSIONS: Unemployment, perception of diabetes' interference with daily living activities, and social support are significantly correlated with poor glycaemic control. Further studies assessing other important clinical and psychosocial factors that may influence glycaemic control are suggested. A younger age range of participants is recommended for better outcomes and interventional implementation of findings.
METHODS: This 6-month cross-sectional study adopted convenience sampling; inclusion criteria were healthy pregnant women, sexually active and living together with their partner for 3 months prior to recruitment into this study. Women who received advice to avoid sexual intercourse, with any medical illness and/or those conceived via assisted reproductive technology were excluded. Participants filled in a questionnaire consisting of demographic details and Malay Version Female Sexual Function Index Questionnaire. Data were analysed using SPSS 24.0; categorical data were analyzed by Chi-square and Fisher exact test.
RESULTS: One hundred pregnant women with a mean age of 31 + 4.31 years old participated. By using the cut-off FSFI score of 26.55, 81 (81%) participants were diagnosed to have sexual dysfunction. The mean FSFI score was 20.41 ± 8.45 (range 2.6-33.5; median 23.6). All the mean FSFI scores of first, second and third trimesters were low with 22.80 ± 10.67, 23.81 ± 7.18 and 18.74 ± 8.43, respectively. The mean score for desire, arousal, satisfaction and pain were significantly lower in the third trimester than earlier gestation. There was a significant difference in the incidence of difficulties in desire, arousal, lubrication, satisfaction and pain between first and second trimester combined, as compared to the third trimester of pregnancy. Trimester of pregnancy was found to have a significant association with the incidence of sexual dysfunction.
CONCLUSION: Sexual dysfunction among pregnant women is a significant burden. Despite being a common health problem, it is often neglected.
METHODS: A comparative cross-sectional study was conducted between August 2016 and May 2018 involving type 2 DM patients with no DR, non-proliferative DR (NPDR), and proliferative DR (PDR). Tear samples were collected using no.41 Whatman filter paper (Schirmer strips) and 5 mL blood samples were drawn by venous puncture. VEGF levels in tears and serum were measured by enzyme-linked immunosorbent assay.
RESULTS: A total of 88 type 2 DM patients (no DR: 30 patients, NPDR: 28 patients, PDR: 30 patients) were included in the study. Mean tear VEGF levels were significantly higher in the NPDR and PDR groups (114.4 SD 52.5 pg/mL and 150.8 SD 49.7 pg/mL, respectively) compared to the no DR group (40.4 SD 26.5 pg/mL, p < 0.001). There was no significant difference in the mean serum VEGF levels between the three groups. There was a fair correlation between serum and tear VEGF levels (p = 0.015, r = 0.263).
CONCLUSION: VEGF levels in tears were significantly higher amongst diabetic patients with DR compared to those without DR and were significantly associated with the severity of DR. There was a fair correlation between serum and tear VEGF levels. Detection of VEGF in tears is a good non-invasive predictor test for the severity of DR. A large cohort study is needed for further evaluation.
METHODS: This study involved life-long residents aged 12 years-old in fluoridated and non-fluoridated areas in Malaysia (n=595). The survey was carried out in 16 public schools by a calibrated examiner, using ICDAS-II criteria. A questionnaire on socio-demographic and oral hygiene practices was self-administered by parents/guardians. Data were analysed using Mann-Whitney U tests and logistic regression.
RESULTS: The overall response rate was 74.4%. Caries prevalence at the dentine level or at the dentine and enamel level was significantly (p⟨0.001) higher among children in the non-fluoridated area (D₁₋₆MFT⟩0 = 82.4%, D₄₋₆MFT⟩0 = 53.5%) than in the fluoridated area (D₁₋₆MFT⟩0 = 68.7%, D₄₋₆MFT⟩0 = 25.5%). Considering only the decayed component of the index, no significant differences were observed between the two areas when the detection threshold was set at enamel caries (D₁₋₃) (p=0.506). However, when the detection criteria were elevated to the level of caries into dentine (D₄₋₆) there were clear differences between the fluoridated and non-fluoridated areas (p=0.006). Exposure to fluoridated water proved a significant predictor for lower caries prevalence in the statistical model. Children whose father and mother had a low monthly income had a significantly higher dentine caries prevalence.
CONCLUSION: Results confirmed existing evidence of the benefit of water fluoridation in caries prevention. Detection criteria set at caries into dentine shows clear differences between fluoridated and non-fluoridated areas. Exposure to fluoridated water and socio-economic status were associated with caries prevalence.
