Clinical safety and efficacy of a preloaded monofocal hydrophobic acrylic intraocular lens in a real-world population.

Background: This study was designed to evaluate visual, refractive and safety outcomes in eyes after they underwent phacoemulsification and implantation of a preloaded monofocal hydrophobic acrylic intraocular lens.

Methods: This was a single center observational study conducted at Ashford and St Peter's Hospitals NHS Foundation Trust, United Kingdom. Patients were included if they had cataract extraction with in-the-bag implantation of the EyeCee® One preloaded intraocular lens from August to October 2019.

Humanized anti-DEspR IgG4 antibody increases overall survival in a pancreatic cancer stem cell-xenograft peritoneal carcinomatosis rat model.

Background: Pancreatic peritoneal carcinomatosis (PPC), with the worst median overall-survival (mOS), epitomizes the incurability of metastatic cancer. Cancer stem cells (CSCs) underpin this incurability. However, inhibitors of CSC-stemness fail to increase mOS in cancer patients despite preclinical tumor-reduction.

Restarting cataract surgery during the COVID-19 pandemic; a prospective study analysing 30 day outcomes after elective cataract surgery in the United Kingdom.

Background: Cataract is a significant cause of preventable blindness in the United Kingdom and worldwide. Prior to the COVID-19 pandemic, cataract surgery was the most commonly performed operation by the National Health Service in the United Kingdom. The aim of this study is to evaluate the safety of elective cataract surgery performed in the United Kingdom in a COVID-19 free hospital during the COVID-19 pandemic.

Refractive surprise after cataract surgery secondary to smeared optics of swept-source optical coherence tomography biometer: a case report.

Background: Inaccurate biometry can lead to the wrong intraocular lens implantation and result in refractive surprise following cataract surgery. It is important to be sceptical of biometry results that do not match the refractive or clinical picture and ask for it to be repeated.

Case Presentation: We present a unique cause of refractive surprise in a patient undergoing cataract surgery.

A Case of Acute Myeloid Leukaemia Presenting as Subacute Intracranial Hypertension in a Young Adult.

We report a case of an 18-year-old woman presenting with headache, papilloedema, and cerebrospinal fluid (CSF) pleocytosis. She was subsequently diagnosed with acute myeloid leukaemia, which is to date the only reported case manifesting as central nervous system-localised disease in an adult. The intracranial hypertension was treated successfully with chemotherapy, acetazolamide, and CSF drainage, with no permanent visual impairment.

A deimmunised form of the ribotoxin, α-sarcin, lacking CD4+ T cell epitopes and its use as an immunotoxin warhead.

Fungal ribotoxins that block protein synthesis can be useful warheads in the context of a targeted immunotoxin. α-Sarcin is a small (17 kDa) fungal ribonuclease produced by Aspergillus giganteus that functions by catalytically cleaving a single phosphodiester bond in the sarcin-ricin loop of the large ribosomal subunit, thus making the ribosome unrecognisable to elongation factors and leading to inhibition of protein synthesis. Peptide mapping using an ex vivo human T cell assay determined that α-sarcin contained two T cell epitopes; one in the N-terminal 20 amino acids and the other in the C-terminal 20 amino acids.

Pre-clinical considerations in the assessment of immunogenicity for protein therapeutics.

Protein therapeutics offer distinct advantages over other classes of drugs largely due to the high level of target specificity and generally low toxicity. Problems have, however, been encountered with some protein therapeutics inducing undesirable immune responses in patients. This immunogenicity can produce pleiotropic effects including the development of a high affinity B cell-mediated humoral response that is often directed against the therapeutic.
