Wearable microfluidic biosensors with haptic feedback for continuous monitoring of hydration biomarkers in workers.

Real-time monitoring of hydration biomarkers in tandem with biophysical markers can offer valuable physiological insights about heat stress and related thermoregulatory response. These metrics have been challenging to achieve with wearable sensors. Here we present a closed-loop electrochemical/biophysical wearable sensing device and algorithms that directly measure whole-body sweat loss, sweating rate, sodium concentration, and sodium loss with electrode arrays embedded in a microfluidic channel.

Estimated lean body mass is more appropriate than body surface area for scaling glomerular filtration rate and extracellular fluid volume.

Background/aims: To compare body surface area (BSA) with lean body mass (LBM) for scaling extracellular fluid volume (ECV) and glomerular filtration rate (GFR).

Methods: Phase 1: Total body water (TBW), bromide space and LBM were measured with (3)H-water, (77)Br and dual X-ray absorptiometry, respectively, in 6 healthy adults. Phase 2: ECV and GFR were measured with (51)Cr-EDTA in 95 healthy adults and 56 children (0.

Significant and persistent loss of bone mineral density in the femoral neck after haematopoietic stem cell transplantation: long-term follow-up of a prospective study.

Reduced bone mineral density (BMD) has been reported following allogeneic stem cell transplantation (alloSCT) but the effects of autologous SCT (autoSCT) are less well characterized. We performed a prospective study of BMD changes and its determinants in 44 SCT recipients (38 auto and six allo; 30 peripheral blood SCT and 14 bone marrow transplantation). Serial measurements of BMD at the lumbar spine and femoral neck were performed at baseline and at 3, 6, 12 and 24 months, and spinal radiographs were performed at baseline and 12 months.

Lack of effect of intravenous pamidronate on fracture incidence and bone mineral density after orthotopic liver transplantation.

Background/aims: Increased rates of bone loss and fracture have been reported after liver transplantation. The aim of this study was to investigate the effects of a pre-transplant infusion of pamidronate on fracture incidence and bone loss during the first year after transplantation.

Methods: Ninety-nine adults awaiting orthotopic liver transplantation (OLT) were randomised to pamidronate or no treatment.
