METHODS: Sixty-one participants were recruited into a vapers group and a control group. The vapers group was instructed to smoke for 5 minutes, and their nasal resistance was measured pre-procedure and at 1 and 5 minutes post-procedure. The results were compared between both groups.
RESULTS: Repeated measures analysis of variance demonstrated that vaping has no statistically significant effect on total nasal airway resistance.
CONCLUSION: Although the differences between both groups were not statistically significant overall, the vapers group showed a reduction in nasal airway resistance in the short term.
METHODS: A retrospective study (2013-2015) was carried out which involved retrieving relevant data from past records (manual/electronic) of paediatric patients (under 18-years-old) who presented with odontogenic infections to the Paediatric Dentistry and Oral and Maxillofacial clinic. Data collected was organised using descriptive statistics with SPSS version 12.0.1.
RESULTS: A total of 153 patients were identified, of which 83.7% were managed as outpatients. Odontogenic infections were more common in females (52.9%) and preschool children (58.2%). The most cases were seen in 2014 and maximum number of cases per month was 12. Common presentations were pain (62.1%), intraoral swelling (37.9%) and spontaneous pus discharge from the tooth and/or surrounding tissues (67.3%) with higher involvement of primary right molars. Dental panoramic tomograph was the most common radiographic investigation done. Outpatients were commonly managed chairside with pulpal opening (46.1%) at the paediatric dental clinic and 7% underwent extraction under general anaesthesia in day-care setting. Inpatients were admitted for 3 days on average and most commonly definitive care was extraction under local/general anaesthesia (68%). There were 22.7% outpatients and 72.0% inpatients who were prescribed antibiotics.
CONCLUSIONS: Overall, treatment and medications prescribed adhered to current guidelines. There was a tendency to solely prescribe antibiotics in 8.6% of outpatients which is contrary to recommendations.
METHODS: This cross-sectional study employed a validated, self-administered questionnaire which was administered to 543 first-year pharmacy students from nine different private universities. Factor analysis was utilised to extract key factors from the responses. Descriptive and inferential statistics were used to analyse the data.
KEY FINDINGS: Eight factors motivating students' decision to study pharmacy emerged from the responses, accounting for 63.8% of the variance observed. Students were primarily motivated by intrinsic interests, with work conditions and profession attributes also exerting significant influence. In terms of choice of private university, nine factors were identified, accounting for 73.8% of the variance observed. The image of the school and university were most influential factors in this context, followed by university safety, programme attributes and financial factors.
CONCLUSIONS: First-year pharmacy students in the private higher education sector are motivated by intrinsic interest when choosing to study pharmacy over other courses, while their choice of private university is influenced primarily by the image of the school and university.
AIM OF THE STUDY: To evaluate the anti-proliferative activity of local medicinal plant species Clausena lansium Skeels, Clinacanthus nutans (Burm. f.) Lindau, Leea indica (Burm. f.) Merr., Pereskia bleo (Kunth) DC., Strobilanthes crispus (L.) Blume, Vernonia amygdalina Delile and Vitex trifolia L.
MATERIALS AND METHOD: Fresh, healthy and mature leaves of the seven medicinal plants were harvested from various locations in Singapore and Malaysia for Soxhlet, ultrasonication and maceration extractions in three different solvents (water, ethanol and methanol). Cell proliferation assay using water soluble tetrazolium salt (WST-1) assay was performed on twelve human cancer cell lines derived from breast (MDA-MB-231, T47D), cervical (C33A), colon (HCT116), leukemia (U937), liver (HepG2, SNU-182, SNU-449), ovarian (OVCAR-5, PA-1, SK-OV-3) and uterine (MES-SA/DX5) cancer.
RESULTS: A total of 37 fresh leaf extracts from seven medicinal plants were evaluated for their anti-tumour activities in twelve human cancer cell lines. Of these, the extracts of C. lansium, L. indica, P. bleo, S. crispus, V. amygdalina and V. trifolia exhibited promising anti-proliferative activity against multiple cancer cell lines. Further investigation of selected promising leaf extracts indicated that maceration methanolic extract of L. indica was most effective overall against majority of the cancer cell lines, with best IC50 values of 31.5 ± 11.4 µg/mL, 37.5 ± 0.7 µg/mL and 43.0 ± 6.2 µg/mL in cervical C33A, liver SNU-449, and ovarian PA-1 cancer cell lines, respectively.
CONCLUSION: The results of this study provide new scientific evidence for the traditional use of local medicinal plant species C. lansium, L . indica, P. bleo, S. crispus, V. amygdalina and V. trifolia in cancer treatment. These results highlight the importance of the upkeep of these indigenous plants in modern society and their relevance as resources for drug discovery.
