METHODS: This cross-sectional study involved 91 ear swab specimens obtained from patients clinically diagnosed with active CSOM. Swabs were cultured for microbial identification according to a standard protocol. We performed antibiotic susceptibility testing, using the modified Kirby-Bauer disc diffusion method, and the diameter of the inhibition zone was interpreted based Clinical Laboratory Standards Institute guidelines.
RESULTS: Microbial growth was seen in 85 (93.4%) samples, but 6 (6.6%) samples had no growth. Among the samples with growth, 63 (69.2%) were monomicrobial, 13 (14.3%) were polymicrobial, and 9 (9.9%) were of mixed growth with more than three microorganisms. The most common bacteria isolated was Pseudomonas aeruginosa (32.6%) followed by Staphylococcus aureus (16.9%) and Klebsiella spp. (5.6%). The most sensitive antibiotics against P aeruginosa were ceftazidime, meropenem, piperacillin-tazobactam, and cefepime. S aureus showed the highest sensitivity toward rifampin, cefoxitin, and fusidic acid.
CONCLUSIONS: The bacteriological profile of CSOM showed a high prevalence of P aeruginosa, followed by S aureus and Klebsiella spp. with different distributions in different age groups. We observed a declining pattern of their antibiotic sensitivity. It is important to be aware of the current trend of the bacteriological profiles and to revise the antibiotic regime according to both the sensitivity and age groups.Level of Evidence: NA.
RESULTS: In this experiment, thick and short hairy roots were induced at all induction sites of C. annuum while thin, elongated hairy roots appeared mostly at wound sites of C. frutescens. Overall, the hairy root induction percentages of C. frutescens were higher compared with C. annuum. Hairy root initiation was observed earliest using radicles (1st week), followed by cotyledons (2nd week), and hypocotyls (3rd week). Cotyledon explants of both species had the highest induction frequency with all strains compared with the other explants types. Strains ATCC 13333 and ATCC 15834 were the most favourable for C. frutescens while ATCC 43056 and ATCC 43057 were the most favourable for C. annuum. The interactions between the different explants and strains showed significant differences with p-values < 0.0001 in both Capsicum species.
CONCLUSIONS: Both Capsicum species were amenable to A. rhizogenes infection and hairy root induction is recommended for use as an alternative explants in future plant-based studies.
DESIGN: Cross-sectional study.
SETTING: This study is part of a larger national study on the perception of the Malaysian public healthcare professionals on FMSs.
PARTICIPANTS: PHCPs from three categories of health facilities, namely hospitals, health clinics and health offices.
MAIN OUTCOME MEASURES: Qualitative analysis of written comments of respondents' expectation of FMSs.
RESULTS: The participants' response rate was 58% (780/1345) with an almost equal proportion from each public healthcare facility. We identified 21 subthemes for the 623 expectation comments. The six emerging themes are (1) need for more FMSs, (2) clinical roles and functions of FMSs, (3) administrative roles of FMSs, (4) contribution to community and public health, (5) attributes improvement and (6) research and audits. FMSs were expected to give attention to clinical duty. Delivering this responsibility with competence included having the latest medical knowledge in their own and others' medical disciplines, practising evidence-based medicine in prehospital and posthospital care, better supervision of staff and doctors under their care, fostering effective teamwork, communicating more often with hospital specialists and making appropriate referral. Expectations ranged from definite and strong for more FMSs at the health clinics to low expectation for FMSs' involvement in research; to mal-expectation on FMSs' involvement in community and public health programmes.
CONCLUSIONS: There were some remarkable differences in expectations on FMSs from the three different PHCPs. These ranged from being clinically competent and administratively available for patients and staff at the health clinics, to mal-expectations on FMSs to engage in public health affairs. Relevant parties, including FMSs themselves, could take appropriate self-improvement initiatives to enhance public practice of family medicine and patient care.
TRIAL REGISTRATION NUMBER NMRR ID: 08-12-1167.
MATERIALS AND METHODS: This was a cross-sectional study of 400 women from registered non-government organisations (NGOs) in Malaysia who voluntarily answered questionnaires distributed through Google form via emails. Data were analysed using descriptive statistics, independent t-test and one-way ANOVA test.
RESULTS: Four hundred respondents participated in this study. The mean age was 40.42 years old (SD=12.566). The mean score for the studied population was 4.96 (SEM 0.124). Only 58 (14.5%) respondents obtained a score of eight or more, and 235 (58.8%) respondents scored between 4 and 7. The rest of 107 (26.7%) respondents scored 3 and less. There were statistically significant differences in the mean score for level of awareness between marital statuses, menopausal status, number of children and occupation. There were only 273 (68%) respondents who will seek treatment if they experience symptoms of POP. The most frequent reasons for not seeking treatment were unawareness of the availability of medical treatment for POP (69 %).
CONCLUSION: Majority of the respondents have an inadequate level of awareness on POP. Although more than half of the respondents will seek treatment if they experience symptoms of POP, concerns raised by those who chose not to seek treatment should be addressed by a more effective public awareness programme. This includes the unawareness of the availability of medical treatment and the embarrassment to see medical practitioners.
DESIGN: A double-blind randomized controlled trial.
METHODS: This study comprised 295 patients who were randomized into the intracameral (ICM) mydriatic group or topical mydriatic group. Central corneal endothelial cell density (ECD), coefficient of variation (CV), and percentage of hexagonal cells were measured preoperatively and postoperatively at 1 week, 6 weeks, and 3 months with specular microscope.
RESULTS: There was no significant difference in endothelial cell density and endothelial cell loss between the topical and ICM mydriatic groups. At 3 months, the mean endothelial cell density in the ICM group was 2129.76 ± 423.53 cells/mm2 and 2100.54 ± 393.00 cells/mm2 in the topical group (P = 0.539). The endothelial cell loss was 18.60 ± 12.79% in the IC M group and 19.44 ± 11.24% in the topical group (P = 0.550). No significant difference was seen in the percentage of hexagonal cells and coefficient of variation of patients between the 2 groups.
CONCLUSIONS: Intracameral phenylephrine was not associated with increased risk of postoperative endothelial cell loss or morphological changes. It can be safely injected into the anterior chamber for pupil dilatation before phacoemulsification cataract surgery.
METHODS: An integration of fuzzy logic and decision-making trial and evaluation laboratory (DEMATEL) is utilized, and data was collected from a panel of professional experts in Malaysia. Using a cause-effect relationship diagram, the fuzzy DEMATEL method evaluates the causal relationships between factors.
RESULTS: Findings showed that environmental factors play the most significant roles in preventing COVID-19 infection, followed by technology, individual, and social factors. Getting vaccinated is the most crucial factor in the environmental dimension in cutting the spread of COVID-19. Telehealth, the use of personal protective equipments (PPEs), and the adoption of social distancing are the most important measures in technology, individual and social dimensions, respectively.
CONCLUSIONS: This study offered valuable insights for policymakers and healthcare professionals in designing and implementing effective strategies to prevent pandemic disease transmission. Findings can be practically applied to optimize and prioritize infection prevention measures, assign resources more effectively, and guide evidence-based decision-making in the face of evolving pandemic situations. This process involves the active commitment of all parties, including governments, medical health executives, and citizens.
METHODS AND RESULTS: In this study, we have developed a simplified, tissue culture-independent protocol to deliver the CRISPR/Cas9 system through in planta transformation in Malaysian rice (Oryza sativa L. subsp. indica cv. MR 219). Sprouting seeds with cut coleoptile were used as the target for the infiltration by Agrobacterium tumefaciens and we achieved 9% transformation efficiency. In brief, the dehusked seeds were surface-sterilised and imbibed, and the coleoptile was cut to expose the apical meristem. Subsequently, the cut coleoptile was inoculated with A. tumefaciens strain EHA105 harbouring CRISPR/Cas9 expression vector. The co-cultivation was conducted for five to six days in a dark room (25 ± 2 °C) followed by rooting, acclimatisation, and growing phases. Two-month-old plant leaves were then subjected to a hygromycin selection, and hygromycin-resistant plants were identified as putative transformants. Further validation through the polymerase chain reaction verified the integration of the Cas9 gene in four putative T0 lines. During the fruiting stage, it was confirmed that the Cas9 gene was still present in three randomly selected tillers from two 4-month-old transformed plants.
CONCLUSION: This protocol provides a rapid method for editing the rice genome, bypassing the need for tissue culture. This article is the first to report the delivery of the CRISPR/Cas9 system for in planta transformation in rice.
METHODS: The study was focused on assessing the impact of tilapia culture at sites nearer to the AIZ vs more distant sites, the former with a greater likelihood of receiving escapees. Two major sites were chosen; within 5 km (near-cage) and within 5-15 km (far-cage) radii from the AIZ. Fish sampling was conducted using multiple mesh sizes of gill nets (3.7, 5.1, 6.5, 7.6, and 10.2 cm) deployed at the littoral zone of the sampling points. Species diversity, abundance, dietary habits, and habitat preference were investigated.
RESULTS: The CPUE (individual/hour) of native fish species at the far-cage site of the AIZ Reservoir was found to be significantly higher (p < 0.05) than that at the near-cage site. Principal component analysis (PCA) based on diet and habitat preferences showed that the tilapia, O. niloticus had almost overlapping diet resources and habitat with native fish species.
CONCLUSION: We conclude that there is a correlation between the reduced catches of native species (based on CPUE) and the high presence of tilapia. Thus, appropriate actions must be implemented for strategic and effective planning in terms of native fish conservation.
