Despite the extensive use of cellular bone matrices (CBMs) in spine surgery, there is little evidence to support the contribution of cells within CBMs to bone formation. The objective of this study was to determine the contribution of cells to spinal fusion by direct comparisons among viable CBMs, devitalized CBMs, and cell-free demineralized bone matrix (DBM).

Three commercially available grafts were tested a CBM containing particulate DBM (CBM-particulate), a CBM containing DBM fibers (CBM-fiber), and a cell-free product with DBM fibers only (DBM-fiber). CBMs were used in viable states (CBM-particulatev and CBM-fiberv) and devitalized (lyophilized) states (CBM-particulated and CBM-fiberd), resulting in 5 groups. Simvastatin Viable cell counts and bone morphogenetic protein-2 (BMP-2) content on enzyme-linked immunosorbent assay (ELISA) within each graft material were measured. A single-level posterolateral lumbar fusion was performed on 45 athymic rats with 3 lots of each product implanted into 9 animals per group. , the groups with a fiber-based DBM demonstrated significantly higher fusion outcomes compared with the CBM groups with particulate DBM, indicating that the DBM component is probably the key determinant of fusion.

Data from the current study demonstrate that cells yielded no additional benefit in spinal fusion and emphasize the need for well-designed clinical studies on cellular graft materials.

Computed tomography (CT), magnetic resonance imaging, and bone scintigraphy are second-line imaging techniques that are frequently used for the evaluation of patients with a clinically suspected scaphoid fracture. However, as a result of varying diagnostic performance results, no true reference standard exists for scaphoid fracture diagnosis. We hypothesized that the use of high-resolution peripheral quantitative CT (HR-pQCT) in patients with a clinically suspected scaphoid fracture could improve scaphoid fracture detection compared with conventional CT in the clinical setting.

The present study included 91 consecutive patients (≥18 years of age) who presented to the emergency department with a clinically suspected scaphoid fracture between December 2017 and October 2018. All patients were clinically reassessed within 14 days after first presentation, followed by CT and HR-pQCT. If a scaphoid fracture was present, the fracture type was determined according to the Herbert classification system and correlat CT scanning in patients with a clinically suspected scaphoid fracture.

Patient-reported outcome measures (PROMs) comprise valuable data, when combined with traditional clinical information, for patient-centered health outcome assessment.

While PROMs form the foundation of orthopaedic clinical research, they are invaluable tools for clinical care.

PROMs play a critical role in shared decision-making with patients, as they are quantitative measures of patient health (function, pain, and satisfaction).

PROMs should be incorporated into routine postoperative care for effective clinical monitoring and understanding of the response to surgery.

PROMs can be additionally utilized for meaningful clinical research, predictive analytics, and value-based care delivery pathways.

To describe the hemodynamic response to fluid boluses for hypotension in children in a cardiac ICU.

A prospective, observational study.

Single-centered cardiac ICU.

Children in a cardiac ICU with hypotension.

Clinician prescribed fluid bolus.

Sixty-four fluid boluses were administered to 52 children. Fluid composition was 4% albumin in 36/64 (56%), 0.9% saline in 18/64 (28%), and cardiopulmonary bypass pump blood in 10/64 (16%). The median volume and duration were 5.0 mL/kg (interquartile range, 4.8-5.4) and 8 minutes (interquartile range, 4-19), respectively. Hypovolemia/low filling pressures was the most common additional indication (25/102 [25%]). Mean arterial pressure response, defined as a 10% increase from baseline, occurred in 42/64 (66%) of all fluid boluses at a median time of 6 minutes (interquartile range, 4-11). Mean arterial pressure responders had a median peak increase in the mean arterial pressure of 15 mm Hg (43 mm Hg [interquartile range, 29-50 mm Hg] to 58 mm Hg [interquartile ICU, the median dose and duration of fluid boluses were 5 mL/kg and 8 minutes. Peak response occurred shortly following administration and commonly returned to baseline.

CARE Dose 4D modulates mAs through several mechanisms according to patient size and shape, whilst maintaining user-defined reference image quality on Siemens Symbia single-photon emission computed tomography (SPECT)-computed tomography (CT) systems. A 20 kg child reference was used in child protocols prior to software version VB10 and a 75 kg adult thereafter. Quality reference mAs conversion factors are estimated for delivering equivalent mAs to children between two comparable SPECT-CT systems using adult and child references for topogram-based patient-size-related dose level adaptations.

A child phantom was scanned using child protocols on a Siemens Symbia T16 (child reference) and a Siemens Symbia Intevo Bold (adult reference). On each system, scans of the thorax, abdomen and pelvis were acquired with arms up and down, at 80 and 110 kVp. Quality reference mAs settings of 10-50 were used on the Symbia T16 and 40-200 on the Symbia Intevo Bold. These data were used to propose quality reference mAs (adult/child reference) conversion factors according to scan range, arm position and tube voltage.
