BACKGROUND: Entamoeba histolytica is an important etiologic agent of diarrhea. Globally, it is estimated to infect 40 to 50 million people and cause 40,000 to 100,000 deaths per year. Metronidazole is effective but can cause adverse reactions in certain individuals. In search of alternatives, traditional medicinal plants are being studied. Several plants in Family Simaroubaceae have shown anti-amoebic activity. Quassia amara, a member of this family has not been tested.
OBJECTIVE: To determine the effect of Q. amara crude extract on Entamoeba histolytica in vitro.
METHODS: Initial testing of 104 µg/ml ethanolic bark extract was performed. Counts were made after 72 hours. Three trials in triplicates were performed.
Nine (9) dilutions of extract were then tested (18.8 to 5,00 µg/ml). Test tubes were checked for viable amoeba after 24-hour and 72-hour incubation. Minimum inhibitory concentrations (MIC) were determined for the two incubation periods. At least two trials in triplicates for each dilution were performed. metronidazole served as positive control.
RESULTS: At 104 µg/ml incubated for 72 hours, no viable amoeba was obtained and counted. The MIC after 24 hours was 5,000 µg/ml, while the MIC at 72 hours was 37.5 µg/ml.
CONCLUSION: Q. amara crude extract has inhibitory effects on E. histolycain vitro.

Background and Objectives: Heart Failure (HF) remains a major health concern worldwide. In the Philippine General Hospital (PGH), HF is consistently a top cause of mortality and readmissions among adults. The American College of Cardiology (ACC) and European Society of Cardiology (ESC) published guidelines for interventions that improve quality of life and survival, but they are underused and untested for local acceptability. Hospitals overseas used order sets created from these guidelines, which resulted in a considerable decrease in in-hospital mortality and healthcare costs. We aimed to develop an order set for adult patients with acute heart failure (AHF) admitted to the PGH Emergency Department (ED) to improve care outcomes. Methods: This study utilized a mixed methods approach to create the AHF order set. ESC and ACC HF guidelines were appraised using the AGREE II tool. Class I interventions for AHF were included in the initial order set. Through focused group discussions (FGD), clinicians and other care team members involved in the management of AHF patients at PGH ED modified and validated the order set. Stakeholders were asked to use online Delphi and FGD to get a consensus on how to amend, approve, and carry out the order given. Results: Upon review of HF guidelines, 29 recommendations on patient monitoring, initial diagnostic, and therapeutic interventions were adopted in the order set. Orders on subspecialty referrals and ED disposition were introduced. The AHF patient was operationally defined in the setting of PGH ED. The clinical orders fit the PGH context, ensuring evidence-based, cost-effective, and accessible care responsiveness to patients’ needs and suitable for local practice. Workflow changes due to COVID-19 were considered. Potential barriers to implementation were identified and addressed. The final order set was adopted for implementation through stakeholder consensus. Conclusion The PGH developed and adopted its own AHF order set that is locally applicable and can potentially optimize outcomes of care.
