Neuroprotective therapies which focus on factors leading to retinal ganglion cells (RGCs) degeneration have been drawing more and more attention. The beneficial effects of nerve growth factor (NGF) on the glaucoma have been recently suggested, but its effects on eye tissue are complex and controversial in various studies. Recent clinical trials of systemically and topically administrated NGF demonstrate that NGF is effective in treating several ocular diseases, including glaucoma. NGF has two receptors named high affinity NGF tyrosine kinase receptor TrkA and low affinity receptor p75NTR. Both receptors exist in cells in retina like RGC (expressing TrkA) and glia cells (expressing p75NTR). NGF functions by binding to TrkA or p75NTR alone or both together. The binding of NGF to TrkA alone in RGC promotes RGC’s survival and proliferation through activation of TrkA and several prosurvival pathways. In contrast, the binding of NGF to p75NTR leads to apoptosis although it also promotes survival in some cases. Binding of NGF to both TrkA and p75NTR at the same time leads to survival in which p75NTR functions as a TrkA helping receptor. This review discusses the current understanding of the NGF signaling in retina and the therapeutic implications in the treatment of glaucoma.

Objectives: Dynamic and adaptive services that provide timely access to care are pivotal to ensuring patients with palliative needs experience high-quality care. Patients who have palliative care needs may require symptomatic relief with medicines and, therefore, may engage with community pharmacists frequently. However, there is limited evidence for pharmacists’ involvement in community palliative care models. Therefore, a scoping review was conducted to identify pharmacists’ role in community palliative care. Methods: A systematic search strategy was implemented across PubMed, PsychINFO, CINAHL, and Embase databases. Articles were screened by abstract and full text against inclusion and exclusion criteria. Key findings: Five articles (two from Australia, two from England, and one from Scotland) met the inclusion criteria and described interventions involving pharmacists in community palliative care. This review has identified that the inclusion of trained pharmacists in community palliative care teams can improve the quality of care provided for patients with palliative needs. Pharmacists are able to undertake medication reviews and provide education to patients and other healthcare professionals on the quality use of palliative care medicines. Additionally, the underutilization of community pharmacists in palliative care, the need for further training of pharmacists, and improved community pharmacy access to patient information to deliver community palliative care were identified. Conclusion: Pharmacists can play a vital role in community palliative care to enhance the quality of life of patients. There is a need for greater pharmacist education/training, improved interprofessional communication, improved access to patient information and sustainable funding to strengthen community-based palliative care.
