RESUMEN

Outcome-based education (OBE) has brought along a significant development in health professions education in the past decade. The shift from a process-driven to product-driven model of education is valuable for ensuring graduate quality and facilitating global movement of healthcare workers. Such a model can align the expectations of key stakeholders in an era of rapid knowledge expansion and technological advancement. Nevertheless, the experienced benefits of OBE depend on the effectiveness of its implementation. This article therefore provides practical tips and strategies for implementing OBE in order to maximize its potential.

RESUMEN

BACKGROUND: Interprofessional education (IPE) is an instructional approach for equipping health professions students with essential competencies needed to provide collaborative patient-centred care. The implementation and sustainability of IPE are challenging for many institutions. This qualitative study identified barriers and facilitators in the processes of IPE implementation. METHODS: We conducted mixed focus groups (FGs) with faculty members from medicine, dentistry, pharmacy, nutrition and dietetics, nursing, chiropractic, Chinese medicine, and other health sciences programmes; who were involved in the planning of IPE at institutional or programme level, or who participated in IPE activity. Transcripts were analysed using grounded theory. RESULTS: We identified 25 barriers and facilitators, clustered under five major categories of commitment, faculty engagement, IPE design, support, and delivery. CONCLUSIONS: Successful implementation of IPE may hinge on actions in 5 stages; commitment, faculty engagement, IPE design, support, and delivery. The processes will require consistent leadership to break down professional silos and enhance collaborative effort in IPE implementation.

RESUMEN

AIM: To develop 6-O-palmitoyl-ascorbic acid-based niosomes targeted to transferrin receptor for intravenous administration of tocotrienols (T3) in breast cancer. MATERIALS & METHODS: Niosomes were prepared using film hydration and ultrasonication methods. Transferrin was coupled to the surface of niosomes via chemical linker. Nanovesicles were characterized for size, zeta potential, morphology, stability and biological efficacy. RESULTS: When evaluated in MDA-MB-231 cells, entrapment of T3 in niosomes caused 1.5-fold reduction in IC50 value compared with nonformulated T3. In vivo, the average tumor volume of mice treated with tumor-targeted niosomes was 12-fold lower than that of untreated group, accompanied by marked downregulation of three genes involved in metastasis. CONCLUSION: Findings suggested that tumor-targeted niosomes served as promising delivery system for T3 in cancer therapy.

RESUMEN

INTRODUCTION: This paper compares the panel interview (PI) performance with the multiple mini interview (MMI) performance and indication of behavioural concerns of a sample of medical school applicants. The acceptability of the MMI was also assessed. MATERIALS AND METHODS: All applicants shortlisted for a PI were invited to an MMI. Applicants attended a 30-min PI with two faculty interviewers followed by an MMI consisting of ten 8-min stations. Applicants were assessed on their performance at each MMI station by one faculty. The interviewer also indicated if they perceived the applicant to be a concern. Finally, applicants completed an acceptability questionnaire. RESULTS: From the analysis of 133 (75.1%) completed MMI scoresheets, the MMI scores correlated statistically significantly with the PI scores (r=0.438, p=0.001). Both were not statistically associated with sex, age, race, or pre-university academic ability to any significance. Applicants assessed as a concern at two or more stations performed statistically significantly less well at the MMI when compared with those who were assessed as a concern at one station or none at all. However, there was no association with PI performance. Acceptability scores were generally high, and comparison of mean scores for each of the acceptability questionnaire items did not show statistically significant differences between sex and race categories. CONCLUSIONS: Although PI and MMI performances are correlated, the MMI may have the added advantage of more objectively generating multiple impressions of the applicant's interpersonal skill, thoughtfulness, and general demeanour. Results of the present study indicated that the MMI is acceptable in a multicultural context.

RESUMEN

OBJECTIVE: The aims of this study were to examine autonomic nervous system responses by using heart rate variability analysis (HRV), hemodynamic parameters and numeric pain scale (NPS) when either upper (C1 and C2) or lower (C6 and C7) cervical segments were manipulated in volunteers, and whether such response would be altered in acute mechanical neck pain patients after spinal manipulative therapy (SMT). METHODS: A randomized controlled, cross-over, preliminary study was conducted on 10 asymptomatic normotensive volunteers and 10 normotensive patients complaining of acute neck pain. HRV, blood pressure (BP) and heart rate (HR), and NPS were recorded after upper cervical and lower cervical segments SMT in volunteer and patient groups. RESULTS: The standard deviation of average normal to normal R-R intervals (SDNN) increased (83.54 ± 22 vs. 105.41 ± 20; P = .02) after upper cervical SMT. The normalized unit of high frequency (nuHF), which shows parasympathetic activity, was predominant (40.18 ± 9 vs. 46.08 ± 14) after upper cervical SMT (P = .03) with a significant decrease (109 ± 10 vs. 98 ± 5) in systolic BP (P = .002). Low frequency to high frequency (LF/HF) ratio, which shows predominance of sympathetic activity increased (1.05 ± 0.7 vs. 1.51 ± 0.5; P = .02) after lower cervical SMT in the healthy volunteers group. However, there was an increase in SDNN (70.48 ± 18 vs. 90.23 ± 20; P = .02 and 75.19 ± 16 vs 97.52 ± 22; P = .01), a decrease in LF/HF ratio (1.33 ± 0.3 vs. 0.81 ± 0.2; P = .001 and 1.22 ± 0.4 vs. 0.86 ± 0.3; P = .02), which was associated with decreased systolic BP (105 ± 10 vs. 95 ± 9; P = .01 and 102 ± 9 vs. 91 ± 10; P = .02) and NPS scores (3 ± 1 vs. 0; P = .01 and 3 ± 1 vs. 1 ± 1; P = .03) following both upper and lower cervical SMT in the patient's group. The baseline HR was 67 ± 9 vs 64 ± 5 (upper cervical) and 65 ± 7 vs 69 ± 11 (lower cervical) in both the healthy volunteer' and patient' groups. CONCLUSION: Upper cervical SMT enhances dominance of parasympathetic and lower cervical SMT enhances dominance of sympathetic activity in this young volunteer group. However, dominance of parasympathetic activity was found in patients with neck pain that received both upper and lower cervical SMT.

RESUMEN

BACKGROUND: Euphorbia hirta has been reported to possess anti-inflammatory activity. This study was carried out to determine the prostaglandin E 2 (PGE 2 ) inhibition activity of the fractions of the E. hirta aqueous extract on rabbit synovial fibroblast cells (HIG-82). METHODS: E. hirta aqueous extract was fractionated into five fractions (fractions A, B, C, D, and E) by reversed phase flash chromatography. Rabbit synovial fibroblast cells (HIG-82) were activated with phorbol myristate acetate and treated with the fractions. The amount of PGE 2 released into the medium was measured by enzyme-linked immunosorbent assay. RESULTS: Fraction A (0.1, 1, and 10 µg/ml) had the greatest PGE 2 inhibitory effect among the five fractions, and showed a greater extent of PGE 2 inhibition compared to the aqueous extract. In contrast, Fraction E had the greatest stimulatory effect on PGE 2 release. CONCLUSIONS: Fraction A of the aqueous extract inhibited the production of PGE 2 from activated HIG-82 cells to a greater extent than the crude aqueous extract. Bioactive compounds with anti-inflammatory activity are likely to be concentrated in Fraction A of E. hirta aqueous extract.

RESUMEN

BACKGROUND: The Multiple Mini-Interview (MMI) has been used increasingly for selection of students to health professions programmes. OBJECTIVES: This paper reports on the evidence base for the feasibility, acceptability, reliability and validity of the MMI. DATA SOURCES: CINAHL and MEDLINE STUDY ELIGIBILITY CRITERIA: All studies testing the MMI on applicants to health professions training. STUDY APPRAISAL AND SYNTHESIS METHODS: Each paper was appraised by two reviewers. Narrative summary findings on feasibility, acceptability, reliability and validity are presented. RESULTS: Of the 64 citations identified, 30 were selected for review. The modal MMI consisted of 10 stations, each lasting eight minutes and assessed by one interviewer. The MMI was feasible, i.e. did not require more examiners, did not cost more, and interviews were completed over a short period of time. It was acceptable, i.e. fair, transparent, free from gender, cultural and socio-economic bias, and did not favour applicants with previous coaching. Its reliability was reported to be moderate to high, with Cronbach's alpha = 0.69-0.98 and G = 0.55-0.72. MMI scores did not correlate to traditional admission tools scores, were not associated with pre-entry academic qualifications, were the best predictor for OSCE performance and statistically predictive of subsequent performance at medical council examinations. CONCLUSIONS: The MMI is reliable, acceptable and feasible. The evidence base for its validity against future medical council exams is growing with reports from longitudinal investigations. However, further research is needed for its acceptability in different cultural context and validity against future clinical behaviours.

RESUMEN

Euphorbia hirta (E. hirta) is a weed commonly found in tropical countries and has been used traditionally for asthma, bronchitis and conjunctivitis. However, one of the constituents in this plant, quercetin, was previously reported to be mutagenic. This work aimed to determine the level of quercetin in the aqueous and methanol plant extracts and to investigate the mutagenic effects of quercetin and the extracts in the Ames test utilising the mutant Salmonella typhimurium TA98 and TA100 strains. The antimutagenic activity of Euphorbia hirta aqueous and methanol extracts was also studied in Salmonella typhimurium TA98. HPLC analyses showed that quercetin and rutin, a glycosidic form of quercetin, were present in the acid-hydrolysed methanol extract and non-hydrolysed methanol extract respectively. The quercetin concentration was negligible in both non-hydrolysed and acid-hydrolysed aqueous extracts. The total phenolic contents in Euphorbia hirta were determined to be 268 and 93 mg gallic acid equivalent (GAE) per gram of aqueous and methanol extracts, respectively. Quercetin (25 microg/mL) was found to be strongly mutagenic in Salmonella typhimurium TA98 in the absence and presence of S-9 metabolic activation. However, both the aqueous and methanol extracts did not demonstrate any mutagenic properties when tested with Salmonella typhimurium TA98 and TA100 strains at concentrations up to 100 microg/mL in the absence and presence of S-9 metabolic activation. In the absence of S-9 metabolic activation, both the extracts were unable to inhibit the mutagenicity of the known mutagen, 2-nitrofluorene, in Salmonella typhimurium TA98. On the other hand, the aqueous extracts at 100 microg/mL and methanol extracts at 10 and 100 microg/mL exhibited strong antimutagenic activity against the mutagenicity of 2-aminoanthracene, a known mutagen, in the presence of S-9 metabolic activating enzymes. The results indicated that these extracts could modulate the xenobiotic metabolising enzymes in the liver at the higher concentrations.

RESUMEN

The effect of water extracts of Euphorbia hirta on the histological features and expressions of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) in the rat articular cartilage was investigated. Arthritis was induced in rats using Freund's Complete Adjuvant containing heat-killed M. tuberculosis, and treated with water extracts of E. hirta. Paraffin tissue sections of the arthritic joints were evaluated. The extent of cartilage degeneration was found to be greatest in rats treated with the highest dosage of E. hirta, followed by rats in the untreated group. Rats treated with the intermediary and low dosages of Euphorbia hirta showed improved histology. MMP-13 levels were found to be decreased with decreasing dosages of E. hirta. TIMP-1 levels were found to increase with decreasing dosages of E. hirta. MMP-3 levels fluctuated without any appreciable pattern. Low dosages of E. hirta seem to be beneficial in reducing cartilage degeneration in cases of arthritis.
