AI Article Synopsis
- * The study investigated the relationship between serum cytokines and hip fracture status in older adults, utilizing a proximity extension assay to analyze 46 cytokines in the blood of 40 participants (20 with fractures, 20 without).
- * Significant differences in certain cytokines (like IL-6 and CSF1) were found between fracture and non-fracture patients, suggesting these proteins could serve as potential markers for assessing fracture risk, although more long-term studies are needed to confirm these findings.
Article Abstract
Osteoporosis is a skeletal disease that can increase the risk of fractures, leading to adverse health and socioeconomic consequences. However, current clinical methods have limitations in accurately estimating fracture risk, particularly in older adults. Thus, new technologies are necessary to improve the accuracy of fracture risk estimation. In this observational study, we aimed to explore the association between serum cytokines and hip fracture status in older adults, and their associations with fracture risk using the FRAX reference tool. We investigated the use of a proximity extension assay (PEA) with Olink. We compared the characteristics of the population, functional status and detailed body composition (determined using densitometry) between groups. We enrolled 40 participants, including 20 with hip fracture and 20 without fracture, and studied 46 cytokines in their serum. After conducting a score plot and two unpaired t-tests using the Benjamini-Hochberg method, we found that Interleukin 6 (IL-6), Lymphotoxin-alpha (LT-α), Fms-related tyrosine kinase 3 ligand (FLT3LG), Colony stimulating factor 1 (CSF1), and Chemokine (C-C motif) ligand 7 (CCL7) were significantly different between fracture and non-fracture patients (p < 0.05). IL-6 had a moderate correlation with FRAX (R = 0.409, p < 0.001), while CSF1 and CCL7 had weak correlations with FRAX. LT-α and FLT3LG exhibited a negative correlation with the risk of fracture. Our results suggest that targeted proteomic tools have the capability to identify differentially regulated proteins and may serve as potential markers for estimating fracture risk. However, longitudinal studies will be necessary to validate these results and determine the temporal patterns of changes in cytokine profiles.

Effects of Nursing Home Changes in Antipsychotic Use on Outcomes Among Residents With Dementia.
J Am Med Dir Assoc
December 2024
Department of Internal Medicine, University of Michigan, Ann Arbor, MI, USA.
Objectives: Little information exists on whether nationwide efforts to reduce antipsychotic use among nursing home (NH) residents with Alzheimer's disease and related dementias improved mortality and hospitalization outcomes for residents. Our objective was to examine the effect of NH decreases in antipsychotic use on outcomes for residents with Alzheimer's disease and related dementias.
Design: Observational nationwide study that emulated a series of cluster randomized trials.

Aims: It is unclear if a supportive bandage, removable splint, or walking cast offers the best outcome following low-risk ankle fractures in children. The aim of this study was to evaluate the feasibility of a randomized controlled trial to compare these treatments.
Methods: Children aged five to 15 years with low-risk ankle fractures were recruited to this feasibility trial from 1 February 2020 to 30 March 2023.
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.

Aims: The Exeter femoral stem has a cemented, polished taper-slip design, and an excellent track record. The current range includes short-length options for various offsets, but less is known about the performance of these stems. The aim of this study was to compare the survival of short-length stems with standard-length Exeter stems.
