021) and correlated with the LPM volume change after surgical detachment (P=0.042). The LPM shrank after detachment in the artificial TJR surgery and the muscle detachment affected the movement of the replaced joint.The purpose of this study was to develop a nanoparticle (NP) drug-loading system that enhances the efficiency of indocyanine green (ICG) entry into the tissue under focused ultrasound optimization and, in turn, enables more efficient identification and photothermal therapy (PTT) of the tumor. read more The new NPs were prepared by assembling intermolecular disulfide bonds to form human serum albumin (HSA) NPs and then conjugating those with ICG dye. The NP material was used to test the sensitivity of near-infrared fluorescence imaging and photoacoustic tumor imaging in vitro and in vivo. In addition, the combination of HSA-ICG NPs, focused ultrasound, and microbubbles was used to test PTT on the tumor. HSA-ICG NPs had good biocompatibility and were only a little toxic to cells and mice. In addition, they obviously enhanced tumor near-infrared fluorescence and photoacoustic bimodal imaging. Combined with HSA-ICG NPs, the depth of photoacoustic imaging was increased. Moreover, ICG that was absorbed in the HSA NPs promoted optical absorption in the near-infrared region, which greatly enhanced the PTT treatment's efficiency. This new bimodal tumor-imaging agent enhances the therapeutic effect of PTT and improves the detection of tumors in vivo, thus presenting great potential for use in clinical studies.

Gastrointestinal (GI) complications following total joint arthroplasty (TJA) are rare, but can result in substantial morbidity and mortality, especially when intervention is required. The purpose of this study is to identify modifiable risk factors for the development of GI complications and determine their impact on short-term outcomes following TJA.

We queried patients who underwent primary TJA at a single academic center from 2009 through 2018 and collected data on demographics, comorbidities, operative and perioperative details, and short-term outcomes. Patients who suffered at least one GI complication during the same hospitalization as their TJA were identified. The type of GI complication and intervention performed, if necessary, was recorded. Variables that independently affected the risk of GI complication were identified. Multivariate regression was performed to determine the effect suffering a GI complication had on outcomes.

Of 17,402 patients, 106 (0.6%) suffered a GI complication. Constipation/obstruction, followed by diarrhea/malabsorption, hemorrhage, and Clostridium difficile were the most commonly reported complications. Patients suffering a GI complication were significantly older (68.5 vs 63.7, P < .001), less likely to use alcohol (49% vs 65%, P= .008), and had higher incidences of 8 of the 16 comorbidities analyzed (all P < .05). Patients with GI complications had greater lengths of stay (13.2 vs 2.3 days, P < .001), discharge to facility rates (58% vs 16%, P < .001), and in-hospital mortality rates (1.9% vs 0.1%, P= .002).

Patients suffering a GI complication following TJA require longer hospital stays and greater post-acute care resources and have a substantially higher risk of mortality.

Conversion total knee arthroplasty (convTKA) is associated with increased resource utilization and costs compared with primary TKA. The purpose of this study is to compare 1) surgical time, 2) hospitalization length (LOS), 3) complications, 4) infection, and 5) readmissions in patients undergoing convTKA to both primary TKA and revision TKA patients.

The American College of Surgeons National Surgical Quality Improvement Project database was queried from 2008 to 2018. Patients undergoing convTKA (n= 1,665, 0.5%) were defined by selecting Current Procedural Terminology codes 27,447 and 20,680. We compared the outcomes of interest to patients undergoing primary TKA (n= 348,624) and to patients undergoing aseptic revision TKA (n= 8213). Univariate and multivariate logistic regression was performed to identify the relative risk of postoperative complications.

Compared with patients undergoing primary TKA, convTKA patients were younger (P < .001), had lower body mass index (P < .001), and were less likely to be American Society of Anesthesiologist class III/IV (P < .001). These patients had significantly longer operative times (122.6 vs 90.3min, P < .001), increased LOS (P < .001), increased risks for any complication (OR 1.94), surgical site infection (OR 1.84), reoperation (OR 2.18), and readmissions (OR 1.60) after controlling for confounders. Compared with aseptic TKA revisions, operative times were shorter (122.6 vs 148.2min, P < .001), but LOS (2.91 vs 2.95 days, P= .698) was similar. Furthermore, relative risk for any complication (P= .350), surgical site infection (P= .964), reoperation (P= .296), and readmissions (P= .844) did not differ.

Conversion TKA procedures share more similarities with revision TKA rather than primary TKA procedures. Without a distinct procedural and diagnosis-related group, there are financial disincentives to care for these complex patients.

Sarcoidosis is a multisystemic granulomatous disease of unknown cause occurring in young adults. Cardiac sarcoidosis patients are at increased risk for atrioventricular blocks and ventricular arrhythmias. Sinus node dysfunction is scarcely reported.

We report a case of cardiac sarcoidosis revealed by a sinus node dysfunction and focus on cardiac and thoracic imaging to guide diagnosis.

Sinus node dysfunction may be the first manifestation of cardiac sarcoidosis. In unexplained sinus node dysfunction in young patients, advanced cardiac imaging is a key to cardiac sarcoidosis diagnostic. Early recognition of cardiac sarcoidosis enables to start immunosuppressive treatment and discuss implantable cardioverter defibrillator implantation.
