Background: The long-term neuro-ophthalmic outcomes after carotid intervention in patients presenting with preoperative visual symptoms vary widely based on the underlying etiology of retinal ischemia and are not well understood.

Methods: We performed a retrospective review of consecutive patients presenting with retinal ischemia who subsequently underwent carotid intervention from January 2018 to December 2022. Patients were classified into three groups (group I: amaurosis fugax/vascular transient monocular vision loss, group II: ocular ischemic syndrome [OIS], and group III: central/branch retinal artery occlusion).

Article Synopsis
  • Ocular ischemic syndrome (OIS) is a rare but serious condition linked to carotid artery blockage, leading to potential permanent vision loss and requiring early multidisciplinary treatment for better outcomes.
  • A review of 33 studies involving 479 patients found that most patients experienced improved or stable vision after interventions like carotid endarterectomy (CEA) and carotid artery stenting (CAS), with very few complications reported.
  • The research emphasizes the need for increased awareness and early diagnosis of OIS to enhance treatment effectiveness, suggesting a collaborative approach between vascular and eye specialists to improve patient outcomes.

Background: Medications are often needed to manage distressing end-of-life symptoms (eg, pain, agitation).

Objectives: In this study, we describe the variation in prescribing rates of symptom relief medications at the end of life among long-term care (LTC) decedents. We evaluate the extent these medications are prescribed in LTC homes and whether prescribing rates of end-of-life symptom management can be used as an indicator of quality end-of-life care.

Gβγ subunits mediate many different signaling processes in various compartments of the cell, including the nucleus. To gain insight into the functions of nuclear Gβγ signaling, we investigated the functional role of Gβγ signaling in the regulation of GPCR-mediated gene expression in primary rat neonatal cardiac fibroblasts. We identified a novel, negative, regulatory role for the Gβγ dimer in the fibrotic response.

Objectives: Outpatient in-person early palliative care improves quality of life for patients with advanced cancer. The COVID-19 pandemic forced a rapid shift to telehealth visits; however, little is known about how telehealth in outpatient palliative care settings should be optimised beyond the pandemic. We aimed to explore, from the perspective of patients attending an outpatient palliative care clinic, the most appropriate model of care for in-person versus telehealth visits.

Context The impact of the COVID-19 pandemic on health care service and delivery has been profound. In addition to shifting and expanding clinical responsibilities, rapidly evolving information and guidelines during the COVID-19 pandemic has made it difficult for healthcare workers (HCWs) to synthesize and translate COVID-19 information into practice. Objective The objectives of this study are 1) to examine the impact of a telemedicine education program on HCW's self-efficacy and satisfaction and 2) to explore HCWs' experience in the program and context of practice during the COVID-19 pandemic.

Article Synopsis
  • Some patients didn't show up for their appointments at a cancer support clinic, which can mean they have unmet medical needs.
  • Researchers looked at why these no-shows happened by comparing them to patients who did attend.
  • They found that no-shows were often younger, lived farther away, and did not do as well health-wise, showing they needed new ways like virtual visits to help them attend.

Introduction: Communicable disease epidemics and pandemics magnify the health inequities experienced by marginalised populations. People who use substances suffer from high rates of morbidity and mortality and should be a priority to receive palliative care, yet they encounter many barriers to palliative care access. Given the pre-existing inequities to palliative care access for people with life-limiting illnesses who use substances, it is important to understand the impact of communicable disease epidemics and pandemics such as COVID-19 on this population.
