Strategies for management of patients with, or at risk for, medication-related osteonecrosis of the jaws (MRONJ) - formerly referred to as bisphosphonate-related osteonecrosis of the jaws (BRONJ)-were set forth in the American Association of Oral and Maxillofacial Surgeons (AAOMS) position papers in 2007, 2009 and 2014. The position papers were developed by a committee appointed by the AAOMS Board of Trustees and comprising clinicians with extensive experience in caring for these patients, as well as clinical and basic science researchers. The knowledge base and experience in addressing MRONJ continues to evolve and expand, necessitating modifications and refinements to the previous position papers. Three members of the AAOMS Committee on Oral, Head, and Neck Oncologic and Reconstructive Surgery (COHNORS) and three authors of the 2014 position paper were appointed to serve as a working group to analyze the current literature and revise the guidance as indicated to reflect current knowledge in this field. This update contains revisions to diagnosis and management strategies and highlights the current research status. AAOMS maintains that it is vitally important for this information to be disseminated to other relevant healthcare professionals and organizations.
Prior work has established that high socioeconomic deprivation is associated with worse short- and long-term outcomes for patients undergoing coronary artery bypass grafting (CABG). The relationship between socioeconomic status and 90-day episode spending is poorly understood. In this observational cohort analysis, we evaluated whether socioeconomically disadvantaged patients were associated with higher expenditures during 90-day episodes of care after isolated CABG.
We linked clinical registry data from 8728 isolated CABG procedures from January 1, 2012, to December 31, 2018, to Medicare fee-for-service claims data. Our primary exposure variable was patients in the top decile of the Area Deprivation Index. Linear regression was used to compare risk-adjusted, price-standardized 90-day episode spending for deprived against nondeprived patients as well as component spending categories index hospitalization, professional services, post acute care, and readmissions.
A total of 872 patients were categorized as being in the top decile. Mean 90-day episode spending for the 8728 patients in the sample was $55 258 (SD, $26 252). Socioeconomically deprived patients had higher overall 90-day spending compared with nondeprived patients ($61 579 vs $54 557; difference, $3003; P= .001). Spending was higher in socioeconomically deprived patients for index hospitalizations (difference, $1284; P= .005), professional services (difference, $379; P= .002), and readmissions (difference, $1188; P= .008). Inpatient rehabilitation was the only significant difference in post-acute care spending (difference, $469; P= .011).
Medicare spending was higher for socioeconomically deprived CABG in Michigan, indicating systemic disparities over and above patient demographic factors.

To evaluate whether the involvement of surgeons-in-training was associated with increased infection rates, including both prosthetic joint infection (PJI) and surgical site infection (SSI), following primary total knee arthroplasty (TKA).
This was a retrospective review of outcomes following primary total knee arthroplasty. Surgeries were divided into two groups (a) attending-only and (b) trainee-involved. Association with PJI and SSI were evaluated with univariate analysis and multivariate analysis to adjust for sex, age, body mass index (BMI), Charlson Comorbidity Index (CCI), year of surgery, operative time, and hospital/surgeon volume.
A single, large North-American integrated healthcare system between January 1, 2014 and December 31, 2017.
A total of 12,664 primary TKAs with a minimum of one-year (mean of 2-years, range 1-4.5) follow-up were evaluated.
Residents and fellows were more likely to participate in cases with longer operative times (p<0.001) than the attending-only group.

A myriad of intrinsic and extrinsic forces exerted by the cancer cells, the host tissue, and the molecular and cellular microenvironment modulate the morphology of the tumor and its malignant potential through mechanical, biochemical, genetic, and epigenetic cues. Recent studies have investigated how tissue architecture influences cancer biology from tumor initiation and progression to distant metastatic seeding and response to therapy. With a focus on carcinoma, the most common type of cancer, this review discusses the latest discoveries on how tumor architecture is built and how tissue morphology affects the biology and progression of cancer cells.Equilibrium water sorption in stratum corneum (SC) is considered by treating it as a biocomposite with two main phases, namely, corneocytes and lipids. To validate the rule of mixtures for the individual phase sorption isotherms, a new flexible fitting model is introduced by accounting for characteristic features observed in the variations of the thermodynamic correction factors corresponding to the individual sorption isotherms. The comparison of the model fitting performance with that of the five-parameter Park's model shows a remarkably good ability to fit experimental data for different types of sorption isotherms. The effect of the lipids content on the variance of the composite sorption isotherm of stratum corneum is highlighted. The sensitivity analysis reveals that for the typical water content 20-30 wt%, which corresponds to the SC in a stable condition, the sensitivity of the composite sorption isotherm to the variation of the lipids content on dry basis is predominantly positive and sufficiently small. The good agreement observed between the experimental sorption isotherm for SC and the composite isotherm, which is based on the rule of mixtures for the individual phase sorption isotherms, yields a plausible conclusion (hypothesis) that the corneocytes-lipids mechanical interaction during unconstrained swelling of the SC membrane in the in vitro laboratory experiment is negligible.This commentary features the groundbreaking manuscript published in the 1959 issue of Archives of Biochemistry and Biophysics by George L. Ellman. Metabolism activator The studies describe the quantification of thiols in tissues and purified proteins using DTNB (Ellman's Reagent). This highly referenced manuscript is recognized in this anniversary issue because of the impact these studies have played across diverse scientific fields.The effect of Esculetin on pyroptosis and its possible mechanism in endothelium were explored. 10 μg/mL LPS and 0.5 mM ATP were used to stimulate the rat intestinal microvascular endothelial cells. Then add different concentrations of Esculetin (20μM, 40 μM) to the culture medium containing LPS and ATP culturing for 24 h. The expression of p-NF-κB p65, NF-κB p65, I-κB, p-I-κB, NLRP3, ASC, caspase-1, and gasdermin-D were detected by Western blot, and the release level of IL-18 and IL-1β were measured by ELISA. The NLRP3 inhibitor MCC950 was used at the concentration of 10 μM for 4 h to disentangle the potential mechanism of the influence of Esculetin on pyroptosis. In our experiments, the expression of gasdermin-d and important proteins of NF-κB and NLRP3 signaling pathways were inhibited by Esculetin. Besides, Esculetin also attenuated the morphological changes like swelling rupture and pores on the membrane caused by pyroptosis thereby protecting cells from being damaged by pyroptosis. Combining with the effect of Esculetin on proteins above and its protective effect on cell morphology, we believe that Esculetin has an anti-pyroptosis effect. The inhibiting pyroptosis effects mentioned above are similar to MCC950, which means the anti-pyroptosis effects of Esculetin are associated with the NLRP3 signaling pathway. In conclusion, Esculetin inhibits the pyroptosis of microvascular endothelial cells through the NF-κB/NLFP3 signaling pathway and is expected to be conducive in treating pyroptosis-related diseases.Echinococcus granulosus sensu lato (s.l.) is the helminth parasite responsible for cystic echinococcosis, a neglected tropical disease currently affecting millions of people worldwide. Incomplete knowledge on the parasite biochemistry contributes, at least partially, to the limited development of useful biotechnological advances for the infection control. In this sense, little information is available regarding post-translational modifications (PTMs) occurring in E. granulosus s.l. proteins, which ultimately may affect the performance of biotechnological products to be developed. Therefore, we report here a proteomic analysis of the parasite PTMs identified through FindMod software applied to a set of tegumental proteins previously characterized by mass spectrometry (MALDI-TOF/TOF) analysis of protein spots from a 2D electrophoresis gel. Manual searches for already annotated proteins exhibiting such PTMs were also performed within proteome databases of E. granulosus s.l. and other platyhelminthes. In addition, key enzymes involved in PTMs modifications were searched for within E. granulosus s.l. proteome. Finally, the presence of selected PTMs was further confirmed by a high-resolution proteomic approach (nanoLC-MS/MS). A set of 22 different PTMs most likely to be present in the parasite was suggested, 9 of them with high confidence as they were identified in the same m/z fragment by both proteomic techniques (acetylation, deamidation, deamidation followed by methylation, mono- and di-hydroxylation, mono- and di-methylation, S-nitrosylation and phosphorylation). Interestingly, 5 PTMs were herein identified for the first time in E. granulosus s.l. proteins. Our results expand the scarcely studied topic of PTMs in platyhelminthes.Trichinellosis is a zoonosis that causes health and economic problems worldwide. The available therapy is far from perfect as the conventional drugs used against Trichinella spiralis (T. spiralis) are active against the intestinal adult parasites but much less active against encapsulated larvae in muscles. Therefore, this work aimed to evaluate the effect of the anti-angiogenic agent, bevacizumab, on the muscle larvae of T. spiralis. For this aim, T. spiralis-infected mice were treated by two different doses of bevacizumab, thereafter larval counts as well as biochemical and pathological changes were evaluated in the muscles. The larval burden was reduced in the muscles of treated mice, denoting a detrimental effect of bevacizumab against encapsulated Trichinella larvae. Moreover, there was marked improvement of muscle inflammation with the treatment, evidenced by reduction of the proinflammatory cytokines (IL-6 and TNF-α) and regression of the inflammatory infiltrates in histological sections. Amelioration of oxidative stress in the muscle was also observed in treated animals with reduction of malondialdehyde and carbonic anhydrase III and increase in superoxide dismutase levels. Finally, the treatment induced downregulation of the expression of VEGF and CD31, denoting suppressed angiogenesis. All these beneficial effects were found to be dose dependent. In conclusion, bevacizumab exhibited anthelmintic, anti-inflammatory, antioxidant, and anti-angiogenic activities against Trichinella during the muscular phase of infection. Therefore, bevacizumab could be considered as a useful adjuvant treatment in the late stages of trichinellosis.
