To evaluate if local delivery of boron can accelerate bone healing and examine if the bioactive salt impacts the osteogenic response of bone-derived osteoclasts and osteoblasts by the regulation of the Wnt/β-catenin pathway.

Bilateral femoral cortical defects were created in 32 skeletally mature C57 mice. On the experimental side, boric acid (8 mg/kg concentration) was injected locally, whereas on the control side, saline was used. Mice were euthanized at 7, 14, and 28 days. MicroCT was used to quantify bone regeneration at the defect. selleck products Histological staining for alkaline phosphatase and tartrate-resistant acid phosphatase was used to quantify osteoblast and osteoclast activity, respectively. Immunohistochemical antibodies, β-catenin, and CD34 were used to quantify active β-catenin levels and angiogenesis, respectively.

The boron group exhibited higher bone volume and trabecular thickness at 28 days on microCT. Both alkaline phosphatase activity and β-catenin activity was significantly higher in the boron group at 7 days. In addition, CD34 staining revealed increased angiogenesis at 14 days in boron-treated groups. We found boron to have no association with osteoclast activity.

This study shows that local delivery of boron is associated with an increase in osteoblast activity at early phases of healing. The corresponding increase in β-catenin likely supports that boron increases osteoblast activity by the Wnt/β-catenin pathway. Increased angiogenesis at 14 days could be a separate mechanism of increasing bone formation that is independent of Wnt/β-catenin activation.

To assess the effectiveness of reducing contamination using 2 methods of C-Arm draping compared with traditional methods.

The authors simulated an operating room using an extremity drape, commercially available C-Arm drapes, and C-Arm. A black light was placed above the field. A fluorescent powder was placed on the nonsterile portions of the field. Baseline light intensity was recorded by photo. The C-Arm was brought into the surgical field for orthogonal imaging for 15 cycles. A repeat photograph was taken to measure the increase in intensity of the fluorescent powder to assess degree of contamination. This was repeated 5 times for each configuration standard C-Arm drape, a proprietary close-fitting drape, and a split drape secured to the far side with the split wrapped around the C-Arm receiver. Light intensity difference was measured and average change in intensity was compared.

Compared with standard draping, the proprietary close-fitting drape resulted in a 71.3% decrease in contamination (4.84% vs. 16.90%, P = 0.101) that trended toward significance and the split drape resulted in a 99.5% decrease (0.09% vs. 16.90%, P = 0.017) that was statistically significant.

Far side contamination can be reduced by using a split drape connecting the operative table to the C-Arm receiver, effectively "sealing off" contaminants. The proprietary close-fitting drape may also decrease contamination, but this was not statistically significant in this study. Use of the split drape technique will help prevent contamination and may ultimately lead to decreased infection risk.

To determine if prevalent approaches in acetabular fracture surgery provide enhanced anterior and cranial exposure in a cadaveric model.

A Kocher-Langenbeck (K-L) approach (followed by a Gibson approach on the contralateral hip) was performed in the lateral position on 8 cadavers. A Steinmann pin was used to create holes outlining the bony surfaces available for instrumentation before and after a trochanteric osteotomy. All soft tissue was then removed from the pelvis, and a calibrated digital picture was taken. The surface area of the pelvis visualized through each approach was calculated and compared with the contralateral side to assess for a difference in exposure between the Gibson approach and the K-L approach. An increase in exposure of greater than 10% was considered significant. The extent of anterior exposure (with and without a trochanteric osteotomy) was then measured from the greater sciatic notch.

In 2 of 8 cadavers (25%), the Gibson approach yielded an increase in exposure when compared with a K-L approach. The addition of a trochanteric osteotomy yielded on average 1.6 cm (range, 0.7-2.6 cm) of increased anterior exposure in the K-L approaches and 1.5 cm (range 0.9-3.1 cm) in the Gibson approaches.

The Gibson approach did not reliably provide increased anterior exposure compared with a K-L approach in a cadaver model. A trochanteric osteotomy can be expected to add 1-2 cm of increased anterior exposure in both approaches.

Osteoarthritis and obesity are diseases with high prevalence, and they share common etiologies. We investigated the sex-specific genetic susceptibility to hip and knee osteoarthritis necessitating total joint replacement (TJR), and how body mass index (BMI) moderated the heritability of these osteoarthritis phenotypes.

We linked 29,893 twin pairs with information on BMI in the Swedish Twin Registry with the Swedish National Patient Register to identify twins who underwent primary TJR of the hip or knee combined with a concomitant diagnosis of primary osteoarthritis of these joints. Structural equation modeling was used to calculate the heritability of hip and knee osteoarthritis treated with TJR, with estimates adjusted for the first available BMI, birth year, and sex. We also investigated how heritability varied with BMI treated as a continuous variable.

Similar heritability estimates for hip replacement (0.65 [95% confidence interval (CI), 0.59 to 0.70]) and knee replacement (0.57 [95% CI, 0.50 to 0.64]) were found. Heritability decreased with higher BMI in both sexes for hip replacement and in men for knee replacement. In contrast, heritability for knee replacement increased with higher BMI in women; the estimate was 0.37 (90% likelihood interval [LI], 0.25 to 0.49) for a BMI of 20 kg/m2 and 0.87 (90% LI, 0.68 to 0.94) for a BMI of 35 kg/m2.

In our population, heritability explained, on average, about half of the susceptibility to undergo primary TJR of the hip or knee with the indication of primary osteoarthritis, but it varied with BMI and sex. We demonstrated substantial heritability for knee replacement in obese women.

The health system of Liberia, a low-income country in West Africa, was devastated by a civil war lasting from 1989 to 2003. Gains made in the post-war period were compromised by the 2014-2016 Ebola epidemic. The already fragile health system experienced worsening of health indicators, including an estimated 111% increase in the country's maternal mortality rate post-Ebola. Access to safe surgery is necessary for improvement of these metrics, yet data on surgical and anesthesia capacity in Liberia post-Ebola are sparse. The aim of this study was to describe anesthesia capacity in Liberia post-Ebola as part of the development of a National Surgical, Obstetric, and Anesthesia Plan (NSOAP).

Using the World Federation of Societies of Anaesthesiologists (WFSA) Anaesthesia Facility Assessment Tool (AFAT), we conducted a cross-sectional survey of 26 of 32 Ministry of Health recognized hospitals that provide surgical care in Liberia. The surveyed hospitals served approximately 90% of the Liberian population. This rveyed completely met the minimum World Health Organization (WHO)-WFSA standards for health care facilities where surgery and anesthesia are provided.

Overall, we noted several critical gaps in anesthesia and surgical capacity in Liberia, in spite of the massive global response post-Ebola directed toward health system development. Further investment across all domains is necessary to attain minimum international standards and to facilitate the provision of safe surgery and anesthesia in Liberia. The study results will be considered in development of an NSOAP for Liberia.

Connective tissue progenitors (CTPs) resident in native tissues serve as biological building blocks in tissue repair and remodeling processes. Methods for analysis and reporting on CTP quantity and quality are essential for defining optimal cell sources and donor characteristics and the impact of cell processing methods for cell therapy applications. The present study examines the influence of donor characteristics and cell concentration (nucleated cells/mL) on CTP prevalence (CTPs/million nucleated cells) and CTP concentration (CTPs/mL) in bone marrow aspirates (BMAs).

Iliac crest bone marrow was aspirated from 436 patients during elective total knee or hip arthroplasty. Bone marrow-derived nucleated cells were plated at a density of 1.19 × 105 cells/cm2. Colony-forming unit analysis was performed on day 6.

Large variation was seen between donors. Age (p < 0.05) and cell concentration (p < 0.001) significantly influenced CTP prevalence and CTP concentration. For every 1-year increase in age, the on and CTP prevalence (e.g., by removing red blood cells, serum, and non-CTPs or by increasing aspirate volumes). Cell concentration in the BMA can be measured at the point of care and is an appropriate initial assessment of the quality of BMA.
Proper BMA techniques are necessary to obtain a high-quality yield and composition of cells and CTPs. The reduced CTP concentration and CTP prevalence in the elderly may be mitigated by the use of cell processing methods that increase CTP concentration and CTP prevalence (e.g., by removing red blood cells, serum, and non-CTPs or by increasing aspirate volumes). Cell concentration in the BMA can be measured at the point of care and is an appropriate initial assessment of the quality of BMA.
