Balancing risks in febrile hip fracture patients: is surgical delay more dangerous than infection?

Balziano S, Margalit I, Kollender R et al. · 2026 · Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA

Fever often delays urgent hip fracture surgery due to infection concerns. This study found that operating early, despite fever, did not increase complications or death compared to waiting. Thus, early surgery appears to be a feasible…

Romosozumab does not improve volumetric bone mineral density at distal radius but is associated with early changes in bone strength: a prospective study.

Diz-Lopes M, Rovetta CF, Pollastri F et al. · 2026 · Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA

We evaluated how romosozumab affects bone structure, density, and strength at the wrist over 12 months. Volumetric bone mineral density did not increase, but high-resolution quantitative computed tomography imaging showed modest…

Sympathetic transduction to blood pressure following three days in hypobaric hypoxia: Influence of nocturnal periodic breathing.

Fisher JP, Roche J, Duffy AG et al. · 2026 · Autonomic neuroscience : basic & clinical

We investigated whether three days of hypoxic exposure in a hypobaric chamber, and the associated nocturnal periodic breathing (nPB), reduce sympathetic nerve activity (MSNA) transduction to blood pressure (BP). While hypoxia did not…

Comparing the effects of commercial to open initial specimen diversion techniques on clinical outcomes and institutional costs.

Yang EH, Lopez C, Shay SL et al. · 2026 · Infection control and hospital epidemiology

The clinical outcomes associated with using commercial versus open ISDTs (initial specimen diverting techniques) remain unclear. This multicenter study showed that switching from the commercial to open ISDT did not change blood culture…

Lights, Cameras, Action - The influence of lighting and camera position on walking and running kinematic measurements using Theia3D markerless motion capture.

Thomas A, Tucker CB, Lunn DE et al. · 2026 · Journal of biomechanics

Studies investigating the concurrent validity of markerless motion capture (MMC) systems for obtaining joint and segment kinematics have largely failed to consider the impact of ambient lighting and camera position, which can both affect…

Salt exposure disrupts memory retrieval in habituation and conditioned place preference in planaria (Dugesia japonica).

Tazumi T, Prados J, Urcelay GP · 2026 · Journal of comparative psychology (Washington, D.C. : 1983)

This study examined whether saline acts as an aversive stimulus for planarians and how it influences learning and memory. Using saline as an unconditioned stimulus, we first tested conditioned place avoidance. Saline did not support…

Continuous Monitoring by a Wearable Sensor Did Not Enhance Discharge Decision-Making in an Acute Admission Ward: Results of a Randomized Controlled Trial.

Kant N, Garssen SH, Vernooij CA et al. · 2024 · Studies in health technology and informatics

Adding continuous monitoring to usual care at an acute admission ward did not have an effect on the proportion of patients safely discharged. Implementation challenges of continuous monitoring may have contributed to the lack of effect…

Safety and efficacy of autologous haematopoietic stem-cell transplantation with low-dose cyclophosphamide mobilisation and reduced intensity conditioning versus standard of care in refractory Crohn's disease (ASTIClite): an open-label, multicentre, randomised controlled trial.

Lindsay JO, Hind D, Swaby L et al. · 2024 · The lancet. Gastroenterology & hepatology

Background A previous controlled trial of autologous haematopoietic stem-cell transplantation (HSCT) in patients with refractory Crohn's disease did not meet its primary endpoint and reported high toxicity. We aimed to assess the safety…
