RESUMEN
To determine how often care is limited at the end of life and the factors that are associated with this decision, we reviewed the medical records of all patients that passed away in the intensive care units (ICU) of Aga Khan University. We found that a majority of patients had Do-Not-Resuscitate orders in place at the time of death. Our analysis yielded 6 variables that were associated with the decision to limit care. These are patient age, sex, duration of mechanical ventilation, Glasgow Coma Scale (GCS) ≤8 at any point during ICU stay, GCS ≤8 in the first 24 hours following ICU admission, and mean arterial pressure <65 mm of Hg while on vasopressors in the first 24 hours following ICU admission. These variables require further study and should be carefully considered during end of life discussions to allow for optimal management at the end of life.
RESUMEN
INTRODUCTION: Ethics education in surgical residencies is often delivered in an informal and nonstructured manner as part of a "hidden curriculum", leading to few residencies routinely including it in their core curriculum. This systematic review aimed to summarize the delivery modes, curriculum, structure, and effectiveness of ethics educational interventions for surgical trainees. METHODS: We performed a comprehensive database search including MEDLINE, Embase, Scopus and CENTRAL to search for articles describing the implementation of ethics educational interventions for general surgery or subspecialty trainees. RESULTS: A total of 14 studies were included. Only 2 centers performed targeted needs assessment. Curricula covered included informed consent, the doctor-patient relationship, breaking bad news, decision-making, end-of-life care, conflicts of interest, considering patients' personal contexts, and surgical research ethics. Modes of delivery varied across studies, including case-based learning, group discussions, didactic lectures, reading material, role-playing, simulated patients, and ethics morbidity and mortality (M&M) meetings. Evaluations were most commonly via surveys exploring knowledge and self-reported confidence, with only 3 studies measuring actual trainee performance using objective structured clinical examinations. In general, the educational interventions increased trainees' confidence/preparedness in handling ethical dilemmas. CONCLUSION: We recommend comprehensive local needs assessment to guide curricular development and designing specific learning objectives and measurable milestones to ensure evaluation. Educational interventions are best delivered in a graduated manner with the complexity of the topic mirroring residents' real-life clinical responsibilities and experiences. Teaching modalities should be tailored according to the nature of the curricular content being taught to make the learning experience more interactive and effective.

Visual impairment adversely impacts quality of life and affects more than 295 million individuals globally. Currently, there is no cure or tissue regenerative approaches in clinical practice for vision loss caused by corneal disease, glaucoma, cataracts, macular degeneration, diabetic retinopathy, and inherited retinal disease. Stem cells-based therapeutic approaches to diseases causing moderate to severe visual impairment have shown encouraging outcomes in animal models and in vitro studies. The goal of this narrative review is to describe and evaluate the potential of stem cell-based treatment, and their advantages and safety concerns in treating conditions causing vision loss.
