Similarly, the contact pressures during the ankle motion from a neutral position to maximum dorsiflexion were measured. selleck chemicals The tensile load of the Achilles tendon and ankle motion affected the contact pressure between the Achilles tendon and the posterosuperior prominence of the calcaneus. The contact pressure increased with tensile load or ankle dorsiflexion. Conditions with increasing the tensile load of the Achilles tendon or under ankle dorsiflexion increase the contact pressure between the Achilles tendon and the posterosuperior prominence of the calcaneus.Total ankle arthroplasty is an increasingly utilized treatment for ankle arthritis due to decreasing failure rates and improved outcomes. However, the literature on this procedure remains heterogeneous with large variability in outcome reporting methods. PRISMA guidelines were used to systematically review outcome reporting measures used in prospective studies and randomized control trials on total ankle arthroplasty published in 15 high-impact journals between Jan 1, 2009-May 1, 2020. A total of 43 studies were included and outcome measures were grouped into seven categories pain, subjective function, patient satisfaction, complications, objective function, implant survivorship, and imaging. The most common topic of study was implant design followed by differences in outcomes when comparing total ankle arthroplasty and arthrodesis. The most commonly reported outcome measure was post-surgical complications. No study reported on all seven categories, while 22 (51.2%) studies reported on four or more. Subjective measures had significant variability with fifteen different Patient Reported Outcome Measures used across the studies. While the included studies were quite comprehensive, there was little consistency in reporting outcomes after total ankle arthroplasty. With improving outcomes and techniques in total ankle arthroplasty, and thus an expected increase in utilization and number of published studies, efforts should be made to use commonly employed outcome reporting methods to facilitate comparison of results across studies.Results of a Monte Carlo code intercomparison exercise for simulations of the dose enhancement from a gold nanoparticle (GNP) irradiated by X-rays have been recently reported. To highlight potential differences between codes, the dose enhancement ratios (DERs) were shown for the narrow-beam geometry used in the simulations, which leads to values significantly higher than unity over distances in the order of several tens of micrometers from the GNP surface. As it has come to our attention that the figures in our paper have given rise to misinterpretation as showing 'the' DERs of GNPs under diagnostic X-ray irradiation, this article presents estimates of the DERs that would have been obtained with realistic radiation field extensions and presence of secondary particle equilibrium (SPE). These DER values are much smaller than those for a narrow-beam irradiation shown in our paper, and significant dose enhancement is only found within a few hundred nanometers around the GNP. The approach used to obtain these estimates required the development of a methodology to identify and, where possible, correct results from simulations whose implementation deviated from the initial exercise definition. Based on this methodology, literature on Monte Carlo simulated DERs has been critically assessed.
In this observational, retrospective, multicenter study, we aimed to assess the safety of the combination of local metastasis-directed radiotherapy (RT) and immunotherapy (IT) in a cohort of advanced non-small-cell lung cancer (aNSCLC) patients.
We collected clinical data of aNSCLC patients who received concomitant RT and anti-PD-1/PD-L1 inhibitors in seven Italian centers from September 2015 to June 2019. Concomitant RT was defined as delivered ≤4 weeks before or after the first or last administration of immunotherapy, or within two consecutive cycles of ICI. All adverse events apparently related to RT and/or IT were graded according to the Common Terminology Criteria for Adverse Events, version 4.0, and reported in terms of incidence and severity as immune related or RT related, or combined.
We analyzed the clinical charts of 187 patients. Median follow-up time was 23 months, and median overall survival was 16.5 months (range, 3-162). Thirteen patients developed pure RT-related side effects, and 43 patients (23.9%) developed immune-related side effects. No additive toxic effects were observed. A case of grade 5 pulmonary toxicity was recorded as a possible consequence of a combined effect.
This analysis suggests that the combination of concomitant RT and anti-PD-1/PD-L1 agents is safe, and the two toxicity profiles are independent.

We present a 41-year old man with a right frontal enhancing hemorrhagic lesion. Surgery was performed with histopathological findings suggesting a primary central nervous system angiosarcoma. He was discharged uneventfully and received adjuvant chemotherapy and radiotherapy. At 5 months, the follow-up MRI showed two lesions with an acute subdural hematoma, suggesting a relapse. Surgery was again conducted finding tumoral membranes attached to the internal layer of the duramater around the right hemisphere. The patient died a few days later due to the recurrence of the subdural hematoma. This case report illustrates a rare and lethal complication of an unusual tumor. The literature reviewed shows that gross-total resection with adjuvant radiotherapy seems to be the best treatment of choice.
Although there is evidence that interpersonal trauma is associated with cardiometabolic risk in women, previous studies have not assessed the potential role of revictimization (victimization in both childhood and adulthood) among sexual minority women.
We used data from the Chicago Health and Life Experiences of Women study to examine the associations of revictimization (including physical, sexual, and any revictimization) with self-reported psychosocial factors, health behaviors, and cardiometabolic risk factors (e.g., obesity, hypertension, and diabetes). We tested multiple logistic regression models, adjusted for covariates, to estimate odds ratios of the associations between revictimization and cardiometabolic risk.
The sample included 615 sexual minority women with a mean age of 40.0years; 38.7% White. Eighty-three (13.5%) and 101 (16.4%) participants reported experiencing sexual revictimization and physical revictimization, respectively. Each form of revictimization was associated with higher odds of reporting lifetime depression and recent binge eating, but lower odds of having high social support.
