This clinical case report describes sternal reentry performed years after adhesive-enhanced sternal closure using Kryptonite bone cement. This report provides novel data on the late effects of this innovation. We observed that sternal reentry is feasible and safe. The adhesive did not weaken from biodegradation over a period of several years. There was no evidence of adherence to adjacent soft tissues or other nonbony deep mediastinal structures. Surgeons who receive patients who require redoing cardiac surgery after adhesive-enhanced closure with Kryptonite can be reassured that sternal reentry is safe and feasible...

BACKGROUND: Most patients experience moderate to severe pain after total knee arthroplasty (TKA). We hypothesized that intraoperative treatment of cut bone surfaces with local anesthetic (preimplantation immersion anesthesia, PIA) would lead to decreased postoperative pain and opioid consumption. METHODS: Records of 76 patients who underwent unilateral, cemented TKA were retrospectively reviewed. For PIA patients, surgical wounds were immersed in local anesthetic solution immediately prior to component implantation...

This research is an investigation of the feasibility of utilizing phosphogypsum (PG) and phosphate tailings (PTS) for cemented paste backfill. Some experiments were conducted with various combinations of PTS and PG as aggregates, along with slags and/or Portland cement as binders and CaO as an additive. The influence of the PG's ageing time on the consolidation of backfill was also explored. The unconfined compressive strength (UCS), the generated gases and the scanning electron microscope (SEM) were all tested and used in the analysis of backfill characteristics...

Since the emergence of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and Middle East Respiratory Syndrom Coronavirus (MERS-CoV) it has become increasingly clear that bats are important reservoirs of CoVs. Despite this, only 6% of all CoV sequences in GenBank are from bats. The remaining 94% largely consist of known pathogens of public health or agricultural significance, indicating that current research effort is heavily biased towards describing known diseases rather than the 'pre-emergent' diversity in bats...

The rational (de novo) design of membrane-spanning proteins lags behind that for water-soluble globular proteins. This is due to gaps in our knowledge of membrane-protein structure, and experimental difficulties in studying such proteins compared to water-soluble counterparts. One limiting factor is the small number of experimentally determined three-dimensional structures for transmembrane proteins. By contrast, many tens of thousands of globular protein structures provide a rich source of 'scaffolds' for protein design, and the means to garner sequence-to-structure relationships to guide the design process...

Vascularization of tissue-engineered bone is a critical step in maintaining cell viability and advancing cell performance in vivo. In this study, a novel tri-culture system was developed to elicit pre-vascularization of calcium phosphate cement (CPC) scaffold in which human induced pluripotent stem cell-derived mesenchymal stem cells (hiPSMSCs) were seeded together with human umbilical vein endothelial cells (HUVECs) and pericytes. In a two-step methodology design, we first performed osteoinduction of the seeded hiPSMSCs on the CPC scaffold and then incorporated HUVECs and pericytes to the hiPSMSC-colonized CPC scaffold under a favorable culturing condition, with an objective to form a stable and functional capillary-like vascular network that sustained the engineered osseous tissue...

A blue calcium phosphate cement with optimal self-hardening properties was synthesized by doping whitlockite (β-TCP) with copper ions. The mechanism and the kinetics of the cement solidification process were studied using energy dispersive X-ray diffraction and it was found out that hardening was accompanied by the phase transition from TCP to brushite. Reduced lattice parameters in all crystallographic directions resulting from the rather low (1:180) substitution rate of copper for calcium was consistent with the higher ionic radius of the latter...

A novel bioactive vaterite-containing tricalcium silicate bone cement (V5) was successfully synthesized through self hydration and carbonization, by introducing CO2 into the hydration process of Ca3SiO5 (C3S). The purpose of this work is to reduce the adverse effect of the hydration products Ca(OH)2 on the C3S bone cement, and improve further the bioactivity of the C3S bone cement. XRD and FT-IR analysis indicated that vaterite was successfully formed in tricalcium silicate bone cement. The in vitro bioactivity of V5 was investigated by soaking in simulated body fluid (SBF) for various periods (1, 3, 7days), in addition to setting time, compressive strength and cell behavior...

Stabilisation/solidification (S/S), which involves fixation and immobilisation of contaminants using cementitious materials, is one method of treating drill cuttings before final fate. This work considers reuse of stabilised/solidified drill cuttings for forage production in acidic soils. It sought to improve the sustainability of S/S technique through supplementation with the phytoremediation potential of plants, eliminate the need for landfill disposal and reduce soil acidity for better plant growth. Drill cuttings with an initial total petroleum hydrocarbon (TPH) concentration of 17,125 mg kg(-1) and low concentrations of metals were treated with 5%, 10%, and 20% cement dosages...

China has the world's second largest burden of multidrug-resistant tuberculosis (MDR-TB; resistance to at least isoniazid and rifampicin), with an estimated 57,000 cases (range, 48,000-67,000) among notified pulmonary TB patients in 2015. During October 1, 2006-June 30, 2014, China expanded MDR-TB care through a partnership with the Global Fund to Fight AIDS, Tuberculosis, and Malaria (Global Fund). We analyzed data on site expansion, patient enrolment, treatment outcomes, cost per patient, and overall programme expenditure...

There is controversy in the literature regarding the indicated retentive mechanism for implant supported crowns. When adjacent implants are restored, the restoration can be either screw retained, cement retained, or a combination of cement and screw retained. Adjacent implant supported crowns can be restored as individual implant supported crowns or they can be splinted. A classification system is proposed when adjacent implants are restored. The classification system describes currently available options to restore adjacent implants...

The occurrence of extranodal primary B cell non-Hodgkin's lymphoma is rare. Total hip replacement is one of the most common orthopaedic procedures performed. There has been an increased incidence of primary lymphomas involving periprosthetic sites. Chronic inflammation due to metal debris arising from the prosthetic implants has been evidenced as one of the causes for the development of soft tissue lymphomas albeit rarely. We describe a case report of a 77-year-old patient who had underwent a cemented total hip replacement in the past who further developed large B cell primary non-Hodgkin's lymphoma...

Some concrete pavements in the US have recently exhibited premature joint deterioration. It is hypothesized that one component of this damage can be attributed to a reaction that occurs when salt-laden water is absorbed in the concrete and reacts with the matrix. This study examines the absorption of CaCl2 solution in mortar via neutron imaging. Mortar specimens were prepared with water to cement ratios, (w/c), of 0.36, 0.42 and 0.50 by mass and exposed to chloride solutions with concentrations ranging from 0 % to 29...

BACKGROUND: Proximal end of the humerus is a common site for both primary and metastatic bone tumors. Limb salvage with endoprosthetic replacement is the most common means of reconstruction, but it has been proved that cement spacer are more beneficial for inferior shoulder function. Thus, limb salvage can be replaced by cheaper spacers especially in poor societies. PATIENTS AND METHODS: This study included 20 patients, of whom 14 were female, with a mean age of 40...

Silicate-based cements have been developed as a class of bioactive and biodegradable bone cements owing to their good in vitro bioactivity and ability to dissolve in a simulated body fluid. Until recently, however, the in vivo evidence of their ability to support bone regeneration is still scarce. In the present study, a pilot in vivo evaluation of a silicate-based composite bone cement (CSC) was carried out in a rabbit femur defect model. The cement was composed of tricalcium silicate, 45S5 bioglass and calcium sulfate, and the self-setting properties of the material were established...
