Organoids are self-organized cellular clusters in three-dimensional culture, which can be derived from a single stem cell, progenitor or cell clusters of different lineages resembling in vivo tissue architecture of an organ. In the recent years, organoids technology has contributed to the revolutionary changes in stem cell and cancer fields. In this review, we have briefly overviewed the emerging landscape of prostate organoid technology (POT) in prostate research. In addition, we have also summarized the potential application of POT in the understanding of prostate stem cell and cancer biology and the discovery of novel therapeutic strategies for prostate cancer. Lastly, we have critically discussed key challenges that lie in the current state of POT and provided a future perspective on the second-generation of POT, which should better recapitulate cellular behaviors and drug responses of prostate cancer patients.

The Ministry of Health (MOH) has updated the Clinical Practice Guidelines on Chronic Obstructive Pulmonary Disease (COPD) to provide doctors and patients in Singapore with evidence-based treatment for COPD. This article reproduces the introduction and executive summary (with recommendations from the guidelines) from the MOH Clinical Practice Guidelines on COPD, for the information of SMJ readers. Chapters and page numbers mentioned in the reproduced extract refer to the full text of the guidelines, which are available from the Ministry of Health website: https://www.moh.gov.sg/content/moh_web/healthprofessionalsportal/doctors/guidelines/cpg_medical.html. The recommendations should be used with reference to the full text of the guidelines. Following this article are multiple choice questions based on the full text of the guidelines.
