RESUMEN
Objective: The objective of the study is to determine the association of renal impairment (AKI or CKD) with IL-6 levels on mortality, intubation, and length of hospitalization among COVID-19 positive patients. Methods: This is a retrospective cohort study involving chart review of COVID-19 patients with IL-6 levels and admitted from May 2020 to April 2021. The KDIGO criteria was used for determining renal impairment. The subsequent data processing and analysis was carried out using the statistical software, Stata 13. Results: A total of 1,120 charts were included with patients classified as having AKI (33%), CKD (14%), and no renal impairment (58%). Overall mortality and need for intubation were 27% and 30%, respectively, with average length of stay at 12 days. The IL-6 values were divided into low (0 to less than 51 pg/mL), intermediate (51 to 251 pg/mL), and high (greater than 251 pg/mL) tertiles, which showed acceptable sensitivity and specificity for mortality and need for intubation. Conclusion: The presence of renal impairment (CKD or AKI) with increasing IL-6 levels had an effect of increasing risk of adverse outcomes; however, within tertile groups, the presence of renal impairment did not significantly change the risk of adverse outcomes. The tertile groups have acceptable sensitivity and specificity for clinical use.
RESUMEN
Objectives: In the Philippines, patients on chronic hemodialysis with COVID-19 remain admitted in hospitals despite clinical recovery because most free-standing dialysis units require proof of negative conversion via Reverse Transcriptase - Polymerase Chain Reaction (RT-PCR). This study aims to determine the time to negative conversion of COVID-19 RT-PCR testing among adult patients on chronic hemodialysis with COVID-19 admitted at the Philippine General Hospital (PGH) and bring insight in using the symptom or time-based procedure as recommended by local guideline, and ultimately, to ensure delivery of adequate hemodialysis despite being infected with COVID-19, shorten isolation period, and conserve resources especially in resource-limited settings. Methods: This is a retrospective cohort study on all adult patients on chronic hemodialysis who were admitted in PGH after the diagnosis of COVID-19 by RT-PCR between March 2020 and February 2021. Descriptive statistics was used in summarizing the data. Results: A total of 90 patients on chronic hemodialysis who tested positive for COVID-19 via RT-PCR admitted at PGH were included in the study. Most of these patients had moderate COVID-19 at 53.3%. The median number of days from onset of symptoms to clinical recovery was 14.5 days. The median time to first negative conversion was 18 days. Most of these patients had negative conversion at the second week. The correlation coefficient between time to clinical recovery and negative conversion was 0.214. Conclusion: Among adult patients on chronic hemodialysis who were admitted in PGH after the diagnosis of COVID-19, the time to negative conversion was longer compared to the time to clinical recovery with a very weak correlation between the two.
RESUMEN
OBJECTIVES: To compare the conventional style from a multi-modal approach in the teaching of renal physiology among University of the Philippines-College of Medicine (UPCM) first-year medical students in terms of their attitudes and rating scale. METHODS: We conducted an exploratory sequential mixed methods design using an online survey employing a likert scale followed by a focus group discussion of medical students taking the excretory module from 2016 to 2019. Abbreviated plenary live lectures, online videos embedded in a learning management system, patient contact experience ward work, role-playing, and quiz shows are used to integrate the lessons being taught. RESULTS: One-hundred sixty-one respondents out of 185 medical students answered the online survey. We identified that the 67.8% of students found web-facilitated videos extremely effective in understanding renal physiology. Among the online videos, voice-over powerpoint format was proven to be most helpful. Students disclosed that the overall scheme was generally positive and it proved to be enjoyable and provided great learning experiences. CONCLUSION: Applied to a class of millennial students, the pilot flight of the redesigned program attempted to engage the audience in such a way that they would not only memorize the topics by rote, they would be able to understand the topics so they could then correlate them to a real-world, clinical, or a laboratory setting following a multi-modal representation.
