METHOD: The patient was started on a trial of oral cimetidine at a dose of 30 mg/kg and responded well, eventually requiring endoscopic excision only after 2 years. Subsequently, she underwent in vitro fertilisation treatment and stopped taking her cimetidine. After undergoing endoscopic clearance of her papillomata under general anaesthesia, she restarted on cimetidine during her 2nd and 3rd trimester.
RESULTS: Ensuing follow-up demonstrated stable minimal papillomata lesions on her right inferior surface of her vocal cord with no recurrence on her left vocal cord and subglottic area.
CONCLUSION: Cimetidine is generally safe and not known to be associated with any major teratogenic risks during pregnancy. RRP is postulated to worsen in pregnant women due to the increase in oestrogen levels during pregnancy. Hence, adjuvant therapy was imperative for our patient to reduce recurrent papillomata formation during her pregnancy. Larger scale studies are warranted to assess the use of long-term high-dose cimetidine in terms of efficacy and safety in pregnancy.
METHODS: We retrieved data from patients who experienced seizures before age 12 months and were followed for over two years, using electronic patient records at Hospital Raja Perempuan Zainab II in Kelantan, a state in Malaysia's east coast. We retrospectively reviewed these records and assessed clinical outcomes based on the last follow-up.
RESULTS: Of 75 patients, 61 (81.3%) achieved good seizure control or remission. At the last follow-up, 24 (32%) exhibited developmental delay, whereas 19 (25.3%) displayed abnormal neuroimaging. Patients with abnormal background electroencephalographic (EEG) activity, as well as abnormal radiological findings, were more likely to experience poor seizure control and unfavorable developmental outcomes (P
METHODS: This questionnaire development study involved four phases: (i) exploring and understanding the subject matter, (ii) questionnaire development, (iii) content validity testing, and lastly, (iv) field-testing of the questionnaire. For the field-testing phase, a cross-sectional self-administered survey of JoinCT was conducted among cancer patients with various socio-demographic backgrounds and medical conditions. Besides content validity, Cronbach's alpha was used to evaluate the internal consistency of domains, and confirmatory factor analysis was used to evaluate the model fit of the JoinCT framework.
RESULTS: A total of 389 respondents participated in the survey. Based on the results obtained from a field data collection phase, JoinCT consisted of four independent variables domains, namely "knowledge", "perception of benefits", "perception of risks", and "confidence". The only dependent variable was the willingness to participate in a clinical trial. The minimum Cronbach's alpha was 0.937, and the model fit for the overall framework of JoinCT is also excellent with Comparative Fit Index (> 0.90), root mean square error approximation (
METHOD: The nasopharyngeal airway device was modified to use as an airway stent by trimming it to the desired length. Next, the stent was inserted endoscopically and anchored using a novel approach.
RESULTS: The surgery was performed successfully without complications. The patients had full use of their voice while the stent was in situ. No significant granulation tissue was observed.
CONCLUSION: This paper demonstrates the feasibility of using a nasopharyngeal airway device as a temporary stent to prevent restenosis in cases where the patients have a strong demand for phonation. The modified nasopharyngeal airway device is potentially very promising, but cases must be selected carefully to avoid compromising efficacy and safety.
METHODS: The questionnaire was distributed physically and digitally to non-OGS users aged above 60, living in the Klang Valley, Malaysia, using a non-probability sampling approach. A total of 302 data were analysed using PLS structural equation modelling.
RESULTS: The findings indicate that perceived ease of use, functional ability, life-course events, and digital literacy are associated with the elderly's perception of OGS's usefulness, while life-course events, digital literacy, technology anxiety, and facilitating conditions are associated with the perceived ease of use.
CONCLUSION: This study contributes to the OGS literature by addressing ageing complexities with OGS adoption among the elderly population, thereby offering insights for marketers and the government to tailor services and provide relevant support.
MAIN METHODS: A pull-down assay was performed to identify the binding partner of the L-SP40 peptide. Co-immunoprecipitation and co-localization assays with the L-SP40 peptide were employed to confirm the receptor partner in RD cells. The outcomes were validated using receptor knockdown and antibody blocking assays. The L-SP40 peptide was further evaluated for the protection of neonatal mice against lethal challenge by mouse-adapted EV-A71.
KEY FINDINGS: The L-SP40 peptide was found to interact and co-localize with nucleolin, the key attachment receptor of Enteroviruses A species, as demonstrated in the pull-down, co-immunoprecipitation and co-localization assays. Knockdown of nucleolin from RD cells led to a significant reduction of 3.5 logs of viral titer of EV-A71. The L-SP40 peptide demonstrated 80% protection of neonatal mice against lethal challenge by the mouse-adapted virus with a drastic reduction in the viral loads in the blood (~4.5 logs), skeletal muscles (1.5 logs) and brain stem (1.5 logs).
SIGNIFICANCE: L-SP40 peptide prevented severe hind limb paralysis and death in suckling mice and could serve as a potential broad-spectrum antiviral candidate to be further evaluated for safety and potency in future clinical trials against EV-A71.
