Survival without Quality of Life Deterioration in the GORTEC 2014-04 "OMET" Randomised Phase 2 Trial in Head and Neck Cancer Patients with Oligometastases using Stereotactic Ablative Radiotherapy (SABR)-alone or chemotherapy SABR.

Purpose: Patients with oligometastasis may have prolonged survival with multisite stereotactic ablative radiotherapy (SABR). Evidence to support this paradigm is scarce in squamous cell carcinomas of the head and neck cancers (HNSCC). The multicentre open-label randomised, GORTEC 2014-04 (NCT03070366) phase II study assesses survival without definitive quality of life (QoL) deterioration of omitting upfront chemotherapy in oligometastatic HNSCC patients by using SABR-alone.

Artificial intelligence contouring in radiotherapy for organs-at-risk and lymph node areas.

Introduction: The delineation of organs-at-risk and lymph node areas is a crucial step in radiotherapy, but it is time-consuming and associated with substantial user-dependent variability in contouring. Artificial intelligence (AI) appears to be the solution to facilitate and standardize this work. The objective of this study is to compare eight available AI software programs in terms of technical aspects and accuracy for contouring organs-at-risk and lymph node areas with current international contouring recommendations.

[Update of guidelines of the AFSOS, SFRO, SFH, SFNCM, SFCE, GFRP for the management of radio-induced nausea and vomiting].

Background: Radiation-induced nausea and vomiting have mutiple clinical consequences: delay or refusal of irradiation (decreased antineoplastic efficacy of irradiation), altered quality of life, dehydration, malnutrition, interruption of treatment, decompensation of comorbidities and aspiration. These guidelines aim at defining good clinical practices for management of radiation-induced nausea and vomiting (RINV).

Methods: AFSOS, SFRO, SFH, SFNEP, SFCE and GFRP applied an expert consensus methodology to propose updated guidelines.

Observation of Medium-Induced Yield Enhancement and Acoplanarity Broadening of Low-p_{T} Jets from Measurements in pp and Central Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV.

The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum (high p_{T}) hadron trigger in proton-proton and central Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV. A data-driven statistical method is used to mitigate the large uncorrelated background in central Pb-Pb collisions.

Tumor suppressive role of the antimicrobial lectin REG3A targeting the O -GlcNAc glycosylation pathway.

Background And Aims: Antimicrobial proteins of the regenerating family member 3 alpha (REG3A) family provide a first line of protection against infections and transformed cells. Their expression is inducible by inflammation, which makes their role in cancer biology less clear since an immune-inflammatory context may preexist or coexist with cancer, as occurs in HCC. The aim of this study is to clarify the role of REG3A in liver carcinogenesis and to determine whether its carbohydrate-binding functions are involved.

Photoproduction of K^{+}K^{-} Pairs in Ultraperipheral Collisions.

K^{+}K^{-} pairs may be produced in photonuclear collisions, either from the decays of photoproduced ϕ(1020) mesons or directly as nonresonant K^{+}K^{-} pairs. Measurements of K^{+}K^{-} photoproduction probe the couplings between the ϕ(1020) and charged kaons with photons and nuclear targets. The kaon-proton scattering occurs at energies far above those available elsewhere.

Recommendations for Post-Operative RadioTherapy After Complete Resection of Thymoma-a French DELPHI Consensus Initiative.

Introduction: Thymomas are rare intrathoracic malignancies that can relapse after surgery. Whether or not Post-Operative RadioTherapy (PORT) should be delivered after surgery remains a major issue. RADIORYTHMIC is an ongoing, multicenter, randomized phase 3 trial addressing this question in patients with completely R0 resected Masaoka-Koga stage IIb/III thymoma.

Combined cardiovascular effects of ovariectomy and high-intensity interval training in female spontaneously hypertensive rats.

Hypertensive postmenopausal women are more likely to develop adverse cardiac remodeling and respond less effectively to drug treatment than men. High-intensity interval exercise (HIIE) is a nonpharmacological strategy for the treatment of hypertension; however, the effectiveness in women remains uncertain. This study was designed to evaluate ) the effects of HIIE training upon morphological and functional markers of cardiovascular health in female SHR and ) to determine whether the hormonal shift induced by ovariectomy could influence cardiovascular responses to HIIE.

Bioinspired Bottlebrush Polymers Effectively Alleviate Frictional Damage Both In Vitro and In Vivo.

Bottlebrush polymers (BB) have emerged as compelling candidates for biosystems to face tribological challenges, including friction and wear. This study provides a comprehensive assessment of an engineered triblock BB polymer's affinity, cell toxicity, lubrication, and wear protection in both in vitro and in vivo settings, focusing on applications for conditions like osteoarthritis and dry eye syndrome. Results show that the designed polymer rapidly adheres to various surfaces (e.

Comparison of Hyaluronidase-Mediated Degradation Kinetics of Commercially Available Hyaluronic Acid Fillers In Vitro.

Background: The ability to degrade hyaluronic acid (HA)-based fillers with hyaluronidase allows for better management of adverse effects and reversal of suboptimal treatment outcomes.

Objectives: The aim of this study was to compare the enzymatic degradation kinetics of 16 commercially available HA-based fillers, representing 6 manufacturing technologies.

Methods: In this nonclinical study, a recently developed in vitro multidose hyaluronidase administration protocol was used to induce degradation of HA-based fillers, enabling real-time evaluation of viscoelastic properties under near-static conditions.

ψ(2S) Suppression in Pb-Pb Collisions at the LHC.

The production of the ψ(2S) charmonium state was measured with ALICE in Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV, in the dimuon decay channel. A significant signal was observed for the first time at LHC energies down to zero transverse momentum, at forward rapidity (2.

Direct Reprogramming of Hepatocytes Into JAK/Stat-Dependent LGR5+ Liver Cells Able to Initiate Intrahepatic Cholangiocarcinoma.

Somatic cells that have been partially reprogrammed by the factors Oct4, Sox2, Klf4, and cMyc (OSKM) have been demonstrated to be potentially tumorigenic in vitro and in vivo due to the acquisition of cancer-associated genomic alterations and the absence of OSKM clearance over time. In the present study, we obtained partially reprogrammed, SSEA1-negative cells by transducing murine hepatocytes with Δ1Δ3-deleted adenoviruses that expressed the 4 OSKM factors. We observed that, under long-term 2D and 3D culture conditions, hepatocytes could be converted into LGR5-positive cells with self-renewal capacity that was dependent on 3 cross-signaling pathways: IL6/Jak/Stat3, LGR5/R-spondin, and Wnt/β-catenin.

Strengthening the Key Features of Volumizing Fillers: Projection Capacity and Long-Term Persistence.

Volumizing fillers aim to create or restore facial volume in fat layers. To provide strong tissue lifting and long-term persistence, gels are generally designed with stiff properties, characterized by a high storage modulus (G'). However, clinical evidence shows a discrepancy between high G' and good lifting capacities, especially after skin tension has been exerted on the gel.

Development of an ex vivo porcine skin model for the preclinical evaluation of subcutaneously injected biomacromolecules.

Subcutaneous administration is used to deliver systemically-acting biotherapeutics, e.g. antibodies, and locally-acting biomacromolecules, e.

Clinical trials that will change practices: News in palliative radiotherapy.

Palliative radiotherapy is used to alleviate cancer-related symptoms. Symptomatic responses to palliative radiotherapy may however take several weeks, meaning that patients need to survive long enough to derive a real benefit. Oncologists can be optimistic when estimating survival for patients with advanced cancer and as a consequence some patients receiving palliative radiotherapy die before experiencing any gain.

CyberKnife stereotactic radiation therapy for stage I lung cancer and pulmonary oligometastases: is fiducial implantation still relevant?-a cohort study.

Background: Few studies have investigated whether there is a difference in local control or overall survival rates following treatment with robotic stereotactic body radiation therapy (SBRT) with or without prior fiducial marker implantation. Our study aimed to investigate this in patients with primary or secondary lung tumors.

Methods: A retrospective study was conducted at the Institut de Cancérologie de Lorraine of patients treated for primary lung cancer or pulmonary oligometastases with SBRT from January 2013 to July 2016.

Stereotactic body radiation therapy for bone oligometastases.

Stereotactic body radiation therapy is effective for the local management of oligometastases (at most five metastases) with a benefit in survival and local control. Most studies on the management of oligometastases focus on all oligometastatic sites in primary cancer and very few focus on a single oligometastatic site. In particular, there are few data on bone oligometastases, which represent one of the preferred sites for secondary cancer locations.
