Role of chemokine receptors in transplant rejection and graft-versus-host disease.

Organ transplantation increases life expectancy and improves the quality of life of patients experiencing specific conditions such as terminal organ failure. Despite matching efforts between donor and recipient, immune activation can interfere with allograft survival after transplantation if immunosuppression is not used. With both innate and adaptive responses, this is a complicated immunological process.

Establishment and review of educational programs to train optometrists in laser procedures and injections.

Current scope of practice for optometrists in many countries include topical and oral medication with injectable and lasers being added more recently to scope in the United States (US), Canada, the United Kingdom (UK) and New Zealand (NZ). This expanded scope of optometric practice improves access to eyecare and is critical since an ageing population with a higher prevalence of vision disorders and higher healthcare costs looms. Expanded scope has been shown alongside strong safety records.

Vitamin D deficiency after allogeneic hematopoietic cell transplantation promotes T-cell activation and is inversely associated with an EZH2-ID3 signature.

Vitamin D promotes a shift from a proinflammatory to a more tolerogenic immune state in allogeneic hematopoietic cell transplant (HCT) recipients. The dominant mechanism responsible for this shift has not been elucidated. We took a multifaceted approach to evaluating the clinical and immunologic impact of low vitamin D levels in 53 HCT recipients.

Acute community ophthalmology services provided by independent prescribing optometrists supporting hospital eye services during the COVID-19 outbreak.

Background: Specialised Independent Prescribing (IP) community optometrists provided acute eye care during the COVID-19 crisis ensuring that over-stretched hospital emergency eye care was supported, therefore local overall urgent eye care provision was not affected.

Subjects/methods: Number of cases seen by hospital Rapid Access Clinic (RAC) between January 2020 and June 2020 were compared to number of cases seen by IP optometrists in community Acute Primary Care Ophthalmology Service (APCOS) during the same time period. Specifically, comparisons were made between the number of cases seen in RAC and the number of cases seen by APCOS during the period before COVID-19 emergency (January-March 2020) and for a similar timeframe thereafter (April-June 2020).
