The purpose of this case study was to assess the degree to which a 12-month power-based resistance-training program improved bone mineral density (BMD) and fall risk for a 70-year-old postmenopausal woman with osteoporosis and increased risk of falling. After an eight-week strength-development phase, we had the patient perform 44 weeks of resistance training with maximal force mobilization by instructing her to complete as many repetitions as possible during each 60-s set. We used dual-energy X-ray absorptiometry (DEXA) to assess BMD and Dynamic Gait Index (DGI) to assess fall risk before and after the intervention. Post compared to pre-training testing indicated an increase in BMD in the lumbar spine (24%) and femoral neck (29%) resulting in changes in T-score of 0.7 and 0.4 SD, respectively. Testing also revealed a seven-point change in DGI which improved her status to "safe ambulator." After a 12-month period of power training, BMD was increased and fall risk was reduced for a postmenopausal woman with osteoporosis and increased risk of falling.

Haemodynamic measurements during hip hemiarthroplasty surgery for hip fracture.

Aims: There is compelling evidence for the use of cemented hip hemiarthroplasty for displaced intracapsular hip fractures; however, the risks of cement are well reported and in rare cases may be associated with haemodynamic collapse. It is therefore important to improve our understanding of haemodynamic instability, intraoperative monitoring, and strategies to reduce the risk to patients.
Methods: We measured arterial blood pressure using the LiDCO Continuous Non-invasive Arterial Pressure (CNAP) finger cuff during surgery in patients enrolled in the WHiTE 5 trial randomized to cemented or modern uncemented hip hemiarthroplasty at a single recruiting site.
Facilitators and barriers for the implementation of a transmural fall-prevention care pathway for older adults in the emergency department.

Background: Older adults at the emergency department (ED) with fall-related injuries are at risk of repeated falls. National guidelines state that the ED is responsible for initiating fall preventive care. A transmural fall-prevention care pathway (TFCP) at the ED can guide patients to tailored interventions.

Aim: To gain a comprehensive understanding of the practices, attitudes, and thoughts of neurological nurses regarding communication about the risk of stroke recurrence.
Design: This is a mixed-method study with a sequential explanatory design.
Methods: An electronic survey was conducted amongst 280 neurological nurses from 30 hospitals to explore their clinical practice and attitudes towards stroke recurrence risk communication (RC).
Wearable non-invasive neuroprosthesis for targeted sensory restoration in neuropathy.

Peripheral neuropathy (PN), the most common complication of diabetes, leads to sensory loss and associated health issues as pain and increased fall risk. However, present treatments do not counteract sensory loss, but only partially manage its consequences. Electrical neural stimulation holds promise to restore sensations, but its efficacy and benefits in PN damaged nerves are yet unknown.

Gastrointestinal nematode (GIN) infection adversely affects the performance and well-being of forage-based sheep throughout the world. The study objectives were to estimate longitudinal differences between birth seasons and production systems for lamb postweaning growth and indicators of GIN infection. Data were collected on Katahdin lambs within a single flock from 2006 to 2022.
