Methods: Myoblast cells were cultured into young and senescent state before treated with different concentrations of ginger standardised extracts containing different concentrations of 6-gingerol and 6-shogaol. Analysis on cellular morphology and myogenic purity was carried out besides determination of SA-β-galactosidase expression and cell cycle profile. Myoblast differentiation was quantitated by determining the fusion index, maturation index, and myotube size.
Results: Treatment with ginger extracts resulted in improvement of cellular morphology of senescent myoblasts which resembled the morphology of young myoblasts. Our results also showed that ginger treatment caused a significant reduction in SA-β-galactosidase expression on senescent myoblasts indicating prevention of cellular senescence, while cell cycle analysis showed a significant increase in the percentage of cells in the G0/G1 phase and reduction in the S-phase cells. Increased myoblast regenerative capacity was observed as shown by the increased number of nuclei per myotube, fusion index, and maturation index.
Conclusions: Ginger extracts exerted their potency in promoting muscle regeneration as indicated by prevention of cellular senescence and promotion of myoblast regenerative capacity.
METHODS: This was a descriptive cross-sectional study undertaken in the Hospital Universiti Sains Malaysia from April 2011 to March 2012. S. maltophilia isolated from various clinical specimens were included in the study. Antimicrobial susceptibility testing was done using the epsilometer test (E-test) and interpreted according to the guidelines of the Clinical and Laboratory Standards Institute. In the synergy test, the isolates were tested against six different antimicrobial combinations.
RESULTS: In total, 84 S. maltophilia isolates were collected and analysed. According to the E-test, the antimicrobial susceptibility of trimethoprim-sulfamethoxazole (TMP-SMX), tigecycline, and ciprofloxacin was 100%, 91.1%, and 88.9% respectively. The antimicrobial combination of TMP-SMX and ceftazidime showed the highest synergistic effect.
CONCLUSION: TMP-SMX remains the antimicrobial of choice to treat S. maltophilia infection. TMP-SMX and ceftazidime was the most effective combination in vitro.
OBJECTIVE: This study aimed to compare the effects of self bladder emptying and indwelling Foley bladder catheterization for planned cesarean delivery on the rate of postpartum urinary retention and maternal satisfaction.
STUDY DESIGN: A randomized controlled trial was conducted in a tertiary university hospital from January 10, 2022 to March 22, 2023. A total of 400 participants scheduled for planned cesarean delivery were randomized: 200 each to self bladder emptying or indwelling Foley catheter. The primary outcomes were postpartum urinary retention (overt and covert) and maternal satisfaction with allocated bladder care. Analyses were performed using t test, Mann-Whitney U test, chi-square test, or Fisher exact test, as appropriate. Logistic regression was used to adjust for differences in characteristics.
RESULTS: Postpartum urinary retention rates were 1 per 200 (0.6%) and 0 per 200 (P>.99) (a solitary case of covert retention) and maternal satisfaction scores (0-10 visual numerical rating scale), expressed as median (interquartile range) were 9 (8-9.75) and 8 (8-9) (P=.003) in the self bladder emptying and indwelling Foley catheter arms, respectively. Regarding secondary outcomes, time to flatus passage, satisfactory ambulation, urination, satisfactory urination, satisfactory breastfeeding, and postcesarean hospital discharge was quickened in the self bladder emptying group. Pain scores at first urination were decreased and no lower urinary tract symptom was more likely to be reported with self bladder emptying. Surgical field view, operative blood loss, duration of surgery, culture-derived urinary tract infection, postvoid residual volume, and pain score at movement were not different. There was no bladder injury.
CONCLUSION: Self bladder emptying increased maternal satisfaction without adversely affecting postpartum urinary retention. Recovery was enhanced and urinary symptoms were improved. The surgeon was not impeded at operation. No safety concern was found.
MATERIALS AND METHODS: A cross-sectional study was conducted among children who received the COVID-19 vaccine between 3 February and 8 May 2022. Data were collected using a self-administered questionnaire filled out by the parent or legal guardian.
RESULTS: The mean age of the study participants was 9 years old and 43.1% were males. Out of the 195 participants in the study, 62 (31.8%) reported side effects after vaccination. The most frequently reported side effects were pain at the injection site (29.7%, n=58), fever (15.9%, n=31), localised inflammation (10.8%, n=21) and arthralgia/myalgia (9.2%, n=18). There were no reported severe adverse events such as anaphylaxis or myocarditis. Most side effects occurred within the first two days post-vaccination. There was a higher proportion of side effects among children with underlying co-morbidities. No significant differences were observed based on age, weight, ethnicity and the presence of allergies, or the use of premedication.
CONCLUSION: The BNT162b2 vaccine was generally welltolerated in children, with most side effects being mild and self-limiting. These findings support the safety of the COVID-19 vaccine and would guide healthcare professionals, parents and policy-makers in making informed decisions about COVID-19 vaccination, especially among high-risk groups.
