Identify biological Alzheimer's disease using a novel nucleic acid-linked protein immunoassay.

Blood-based biomarkers have been revolutionizing the detection, diagnosis and screening of Alzheimer's disease. Specifically, phosphorylated-tau variants (p-tau, p-tau and p-tau) are promising biomarkers for identifying Alzheimer's disease pathology. Antibody-based assays such as single molecule arrays immunoassays are powerful tools to investigate pathological changes indicated by blood-based biomarkers and have been studied extensively in the Alzheimer's disease research field.

Feasibility of In-Hospital Administration of a Tool to Predict Persistent Post-ICU Functional Impairment Among Older ICU Survivors: A Pilot Study.

Background: A recent international consensus conference called for the development of risk prediction models to identify ICU survivors at increased risk of each of the post-ICU syndrome domains. We previously developed and validated a risk prediction tool for functional impairment after ICU admission among older adults.

Research Question: In this pilot study, we assessed the feasibility of administering the risk prediction tool in the hospital to older adults who had just survived critical illness.

The size of local recurrence influences outcomes in chondrosarcoma: Significant impact observed in grade 2 tumours.

Background: Chondrosarcoma is the second most common bone malignancy. Chondrosarcoma is considered a surgical disease, and the role of surgical margin is important since local recurrence is known to decrease survival. The aim of this study was to investigate the timing of local recurrence and the size of local recurrence in post local recurrence survival in chondrosarcoma.

A Rare Case of Scrotal Swelling: Prostate Cancer Metastasis Masquerading as a Complicated Hydrocele.

Metastasis of prostate cancer to the testes is exceptionally rare. We report the case of a 67-year-old male with a 10-year history of high-risk prostate cancer, previously treated and currently in remission, who presented with left scrotal swelling. The swelling was clinically and radiologically diagnosed as a hydrocele and treated surgically.

Dive medicine capability at Rothera Research Station (British Antarctic Survey), Adelaide Island, Antarctica.

Rothera is a British Antarctic Survey research station located on Adelaide Island adjacent, to the Antarctic Peninsula. Diving is vital to support a long-standing marine science programme but poses challenges due to the extreme and remote environment in which it is undertaken. We summarise the diving undertaken and describe the medical measures in place to mitigate the risk to divers.
