Impaired balance is a key symptom following acute concussion. Unfortunately, the recommended clinical balance assessment lacks sensitivity and discriminative ability, relying on the experience of the clinician for interpretation. The aim of this pilot study is to explore smartphone technology to remotely assess balance impairment in people with acute concussion.

Introduction And Hypothesis: Vaginal pessaries are the mainstay of the non-surgical management of pelvic organ prolapse (POP). A flexible silicone irregular hexagonal (SIH) pessary was developed based on the results of a prior vaginal case study. We hypothesised that the SIH pessary would have a higher rate of retention and self-management than the polyvinyl chloride (PVC) pessary.

Article Synopsis
  • Functional tests like the 6-minute walk test (6MWT) are essential in tracking recovery, especially in orthopedic surgeries, but traditional testing often occurs in controlled settings, limiting use.
  • A study involved patients using smart watches to record their own 6MWT at home, comparing results to formal testing sessions at 6 and 12 weeks after surgery.
  • Results indicated a strong correlation between self-administered and formally tested 6MWT scores, suggesting that patient-recorded tests can effectively monitor rehabilitation progress remotely.

Metastasis-directed therapy (MDT) for oligometastatic prostate cancer (PCa), including stereotactic body radiotherapy (SBRT), has shown promise but is still considered investigational. This is the 5-year analysis of the TRANSFORM trial, the largest prospective cohort of men with oligometastatic PCa treated with SBRT-based MDT. The primary endpoint was 5-year treatment escalation-free survival (TE-FS), defined as freedom from any new cancer therapy other than further SBRT.

After moderate to severe traumatic brain injury (TBI), sleep disturbance commonly emerges during the confused post-traumatic amnesia (PTA) recovery stage. However, the evaluation of early sleep disturbance during PTA, its recovery trajectory, and influencing factors is limited. This study aimed to evaluate sleep outcomes in patients experiencing PTA using ambulatory gold-standard polysomnography (PSG) overnight and salivary endogenous melatonin (a hormone that influences the sleep-wake cycle) assessment at two time-points.

Objective: Given the high variability in traumatic brain injury (TBI) outcomes and relative lack of examination of the influence of noninjury factors on outcome, this study aimed to examine factors associated with functional outcome at 1 and 2 years after moderate to severe TBI, including both preinjury and injury-related factors.

Design: Observational cohort study.

Setting: Inpatient hospital recruitment with outpatient follow-up at 1 and 2 years post injury.

Article Synopsis
  • The study investigates the outcomes of using pre-bent patient-specific spinal rods (PSSR) for correcting adult spinal deformities, aiming to assess the effectiveness and complications associated with their use.
  • A total of 20 patients undergoing surgery were evaluated over a follow-up period of about 25 months, with noteworthy improvements observed in patient-reported outcomes and satisfaction scores.
  • Despite overall success, some patients experienced junctional complications, particularly those without adequate interbody cage support, indicating a need for careful surgical planning.

Background: Prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/computed tomography (CT) has become an increasingly established imaging modality in the staging of prostate cancer (PCa). Numerous PSMA-based tracers are currently available, however, there is a lack of consensus on the optimal radiotracer(s) for PSMA PET/CT. This study aims to investigate whether Fluorine-18 (F)-labelled PSMA PET/CT is significantly different from Gallium-68 (Ga) in primary diagnosis and/or secondary staging of prostate cancer following biochemical recurrence.

Objectives: Primary objectives: To determine the additive value of prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) in the risk stratification of men with newly diagnosed prostate cancer (PCa) who would have otherwise been deemed suitable for active surveillance (AS). Specifically, we aim to determine if PSMA PET/CT can detect a cohort of men on AS that are in fact high risk and likely to experience unfavourable outcomes should they remain on their current treatment pathway.

Secondary Objectives: to determine the additive value of PSMA PET/CT to repeat multiparametric magnetic resonance imaging (mpMRI) of the prostate and explore whether a confirmatory biopsy may be avoided in men with a negative PSMA PET/CT and a negative repeat mpMRI of the prostate (Prostate Imaging-Reporting and Data System score of <3).

Purpose: With two-thirds of adults presenting for a videofluoroscopy swallow study (VFSS) with oesophageal abnormalities, it seems prudent to include visualisation of the oesophagus, in the context of the entire swallow process, to provide further information to the diagnostic team. This study aims to evaluate the ability of speech-language pathologists (SLPs) to interpret oesophageal sweep on VFSS and the relative improvement in that ability with additional training.

Method: One hundred SLPs attended training in oesophageal visualisation during VFSS, based on a previous study.

Background: Moderate to severe levels of persistent knee pain have been estimated to affect up to 25% of people 3-months or more after a total knee replacement. It is unknown whether the type of rehabilitation pathway is associated with persistent high pain after surgery. Using a prospectively followed Australian cohort who underwent total knee replacement for knee osteoarthritis, this study aimed to i) report the incidence of high-intensity knee pain (defined as a score ≤ 15 on the Oxford Knee Score pain subscale) across time and ii) identify whether referral to inpatient rehabilitation was one of the predictors of persistent pain at 3-months post-surgery.

Background: Conflicting reports exist about the effect of offset variation on functional outcomes following total hip arthroplasty. Reproducing native hip offset is thought to optimize function by restoring biomechanics and appropriately tensioning the hip abductor muscles. The aim of this study is to assess the effect of failing to restore global hip offset in comparison to the native contralateral hip.
