To assess the effects of a resin cement in high and low viscosity and distinct conditioning of the intaglio surface of lithium disilicate glass-ceramic crowns on fatigue performance of the crowns.

Prosthetic preparations (full-crown) in resin epoxy and crowns in lithium disilicate glass-ceramic were machined and allocated considering 2 factors (n=10) "surface treatment" (HF - 5% hydrofluoric acid etching, followed by silane application; or E&P-self-etching ceramic primer) and "resin cement" (high or low viscosity). The preparations were etched with 10% hydrofluoric acid and an adhesive was applied. The intaglio surfaces of the ceramic crowns were treated as aforementioned (HF or E&P) and luted with high or low viscosity. The bonded sets were subjected to fatigue testing (step-stress approach initial load of 200N, step-size of 50N, 10,000 cycles/step, 20Hz) and complementary analyses (fractographic, topographic, and cross-sectional bonded interfacial zone analyses) were performed.

To evaluate the accuracy of metal 3D printed frameworks (MEP group) for removable partial dentures (RPDs) by digital superimposition, in comparison to that of frameworks produced by the conventional (CON group) and resin printing/casting (RPC group) workflows.

A partially edentulous maxillary dentiform was prepared with rest seats and guiding planes on the right canine, left first premolar, and left second molar. Thirty master casts were prepared via repeated impressions of the dentiform. Frameworks were fabricated by three different workflows (n=10 for each group). The internal discrepancies of the frameworks were assessed at 12 points by digital scanning with an optical triangulation principle-based tabletop scanner and superimposition using a reference best-fit alignment method. First, the master cast was scanned alone. Subsequently, a thin silicone material was applied to the framework and fitted onto the master cast, after which the framework was removed. Finally, the master cast with the silicone material attached was rescanned. The data from the two scans were matched, with the reference being the area not occupied by the silicone.

For the CON, MEP, and RPC groups, respectively, the mean overall internal discrepancies (279.72µm, 241.02µm, and 331.70µm), and the mean internal discrepancies on palate areas (292.92µm, 250.72µm, and 355.84µm) and rest seat areas (240.12µm, 211.91µm, and 259.26µm) did not significantly differ among the three fabrication methods (p=0.558, 0.542, and 0.774).

The reference best-fit alignment of scan datasets is a useful approach to evaluate the internal discrepancy of frameworks. Metal 3D printing produces RPD frameworks that are comparable to conventional frameworks and meet clinical standards.

MEDLINE, CINAHL, AMED and SPORTDiscus were systematically searched in May 2021. Studies were included if they used grey-scale USI or power Doppler and reported a USI procedure to assess the first MTPJ. Screening and data extraction were performed by two independent assessors. The scoping review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews (PRISMA-ScR). A total of 403 citations were identified for screening, with 36 articles included in the final analysis. There was wide variation in USI acquisition procedures used to evaluate the first MTPJ. Inconsistencies in reporting may be attributable to the number of elements the USI acquisition procedure encompasses, which include the model of the USI device, the type of transducer, USI modalities and settings, patient position, transducer orientation, surfaces scanned and the scanning technique used. The review found inconsistencies against international guidelines and limited implementation of consensus-based recommendations to guide image acquisition. Current guidelines require further refinement of anatomical reference points to establish a standardised USI acquisition procedure, subsequently improving interpretability and reproducibility between USI studies that evaluate the first MTPJ.When this article was written, it coincided with the 11th anniversary of the installation of our PET/MR device in Munich. In fact, this was the first fully integrated device to be in clinical use. During this time, we have observed many interesting behaviors, to put it kindly. However, it is more critical that in this process, our understanding of the system also improved - including the advantages and limitations from a technical, logistical, and medical perspective. The last decade of PET/MRI research has certainly been characterized by most sites looking for a "key application." There were many ideas in this context and before and after the devices became available, some of which were based on the earlier work with integrating data from single devices. These involved validating classical PET methods with MRI (eg, perfusion or oncology diagnostics). More important, however, were the scenarios where intermodal synergies could be expected. In this review, we look back on this decade-long journey, at the challenges overcome and those still to come.
Heightened familial stress and distress during the COVID-19 pandemic may lead to increased negative parenting practices, particularly for parents with substantial adverse childhood experiences (ACES).

To determine whether families' COVID-19-related distress is associated with young children's emotional/behavioral functioning via negative parenting, and whether these relationships vary based on parents' ACEs.

Participants were 267 parents of children ages 1.5-5years recruited from five primary care sites across the United States.

Participants completed internet questionnaires including measures of demographics, parent ACES, negative parenting, parent mental health, and COVID-19 distress. We used regression analyses to test a moderated mediation model in which the relationship between COVID-19 distress and child emotional/behavioral problems is mediated by negative parenting, and both the direct and indirect effects of COVID-19 distress on child emotional/behavioral problems is moderated by parents' ACEanding of factors influencing negative outcomes in children during the pandemic's acute phase and may have implications for the development of targeted interventions to improve families' adjustment in the future.Breast cancer with HER2-amplification accounts for 20 % of breast cancers. The management of patients has dramatically changed with the advent of anti-HER2 treatment, especially the monoclonal antibodies since 2000 in the metastatic and (neo)-adjuvant setting, leading to an improvement of patient outcomes. If therapeutic arsenal has been gradually enhanced with the targeting of HER receptors family, resistances to these treatments are observed, hence the development of new therapeutic strategies. DL-Thiorphan clinical trial This review provides an updated look of novel therapeutic strategies in HER2-positive breast cancer, as well as future perspectives, both in the adjuvant and metastatic setting.The tumor biopsy remains essential for breast cancer diagnosis and characterization. Indeed, the treatment is decided according to histological subtype, and according to the presence of targetable molecular alterations. Notably, the presence of hormone receptors, ERBB2 hyperexpression or the existence of PIK3CA or ESR1 mutations are among the alterations commonly investigated. But these biological characteristics are determined only partially by tumor biopsy, due to tumor heterogeneity or tumor plasticity that happens spontaneously or under treatment. Liquid biopsy, and in particular circulating tumor DNA and circulating tumor cells, is a non-invasive method to identify and characterize the presence of cancer in the blood. The aim of this review is to determine the value of liquid biopsy to enhance or replace the data provided by a tumor biopsy.HER2 is an important prognostic and predictive biomarker in breast cancer. Its detection makes it possible to define which patients will benefit from a targeted treatment. While assessment of HER2 status by immunohistochemistry in positive vs negative categories is well implemented and reproducible, the introduction of a new "HER2-low" category could raise some concerns about its scoring and reproducibility. We herein described the current HER2 testing methods and the application of innovative machine learning techniques to improve these determinations, as well as the main challenges and opportunities related to the implementation of digital pathology in the up-and-coming AI era.Metastatic breast cancer is the second most common cause of brain metastasis (BM), and this problem is particularly marked for the amplified HER2 subtype (HER2+), with a cumulative incidence reaching up to 49 % in the ER-/HER2+ subgroup. Literature review shows that therapeutic progress has been major since the marketing of systemic anti-HER2+ treatments, with life expectancies now relatively unaffected by brain development. The recommended treatments are, on the one hand, specific treatment for brain development and, on the other hand, appropriate systemic treatment. Regarding local treatments, we will always favor surgery when possible, especially for large metastases, and stereotaxic radiotherapy, possibly iterative. One should be wary of whole brain irradiation which has never been shown to improve overall survival, but which is clearly associated with more cognitive toxicities. All the systemic anti-HER2 treatments currently on the market have shown efficacy on BM from HER2+ breast cancer and must therefore be chosen above all on the basis of their potential activity on the systemic disease at the time of cerebral evolution. If BM evolution happen without concomitant systemic progression, and local treatment can control it, it is not recommended to change the current medical treatment. Finally, randomized clinical studies opened to patients with active brain disease are starting to be published. The first of them showed the benefit of the triple combination tucatinib-trastuzumab-capecitabine in this context.The emergence of a new tumor entity called HER2-low breast cancer leads us to reconsider therapeutic indications in patients whose tumors were usually considered as luminal or triple negative. The development of antibody-drug conjugates (ADCs) allows using HER2 as a vector of a cytoxic drug with significant clinical efficacy in breast cancer with low HER2 expression. Trastuzumab deruxtecan monotherapy is currently evaluated in phase III trials in HER2-low patients, but also in combination in earlier phase studies. Many ADCs are in development, with highly anticipated results. The toxicities of these various ADCs seem manageable and compatible with prolonged administration. Her2-low breast cancer subtype may benefit from dedicated therapeutic strategies in the next few years.
