This study reviews the diagnostic utility of ultrasound-guided core biopsy for investigating head and neck lumps. Overall, 287 ultrasound-guided core biopsies were reviewed between May 2017 and April 2019 at a single tertiary site for head and neck cancer. On initial ultrasound-guided core biopsy, a diagnostic sample was obtained in 94.4 per cent of patients and in 83.7 per cent of patients with lymphoma. Where the initial ultrasound-guided core biopsy was non-diagnostic, 50 per cent of samples were diagnostic on repeat ultrasound-guided core biopsy. Overall, five complications were seen related to ultrasound-guided core biopsy, and all were managed conservatively. No cases of disease recurrence were identified at the biopsy site. Ultrasound-guided core biopsy is a safe procedure with a high diagnostic yield when investigating head and neck lumps. Patients whose ultrasound-guided core biopsies were non-diagnostic should be considered for excisional biopsy over repeat ultrasound-guided core biopsy.

Leukocyte telomere length (LTL) has been shown to predict Alzheimer's disease (AD), albeit inconsistently. Failing to account for the competing risks between AD, other dementia types, and mortality, can be an explanation for the inconsistent findings in previous time-to-event analyses. Furthermore, previous studies indicate that the association between LTL and AD is non-linear and may differ depending on apoli
