Background: EORTC 24971 was a phase III trial demonstrating superiority of induction regimen TPF over PF, in terms of progression-free (PFS) and overall survival (OS) in locoregionally advanced unresectable HNSCC. We conducted a retrospective analysis of prospectively collected data aiming to evaluate whether only HPV(-) patients (pts) benefit from adding docetaxel to PF, in which case de-intensifying induction treatment in HPV(+) pts could be considered. Methods: Pre-therapy tumor biopsies (blocks or slides) were assessed for high-risk HPV by p16 immunohistochemistry, PCR and qPCR...

BACKGROUND: Executive dysfunction is common in substance use disorder (SUD) populations and hinders treatment. We previously found that 50% of residents in SUD therapeutic communities had been hospitalized for head injuries; this was a significant determinant of cognitive impairment. The current study aimed to establish whether cognitive remediation improves executive functions (EFs) and self-regulation in an ecologically valid sample of female residents attending SUD therapeutic community treatment, including those with past head injuries and psychiatric comorbidities...

To visually perceive opportunities for action, athletes rely on the movements of their eyes, head and body to explore their surrounding environment. To date, the specific types of technology and their efficacy for assessing the exploration behaviours of association footballers have not been systematically reviewed. This review aimed to synthesise the visual perception and exploration behaviours of footballers according to the task constraints, action requirements of the experimental task, and level of expertise of the athlete, in the context of the technology used to quantify the visual perception and exploration behaviours of footballers...

Most fungal infections primarily occur in immunocompromised patients. We describe a case of osteomyelitis involving the first metatarsal head due to Cryptococcus neoformans in a previously healthy immunocompetent patient. She was treated with surgical debridement combined with antifungal drug therapy for 6 months. At 5-year follow-up, she remained symptom free with full range of motion of the first metatarsophalangeal joint. Fungal osteomyelitis should be considered as a possible cause in osteolytic lesions in the metatarsal bone...

PURPOSE: To identify factors associated with a near-miss or safety incident (NMSI) in patients undergoing radiotherapy and identify common root causes of NMSIs and their relationship with incident severity. METHODS: We retrospectively studied NMSIs filed between October 2014 and April 2016. We extracted patient-, treatment-, and disease-specific data from patients with an NMSI (n = 200; incident group) and a similar group of control patients (n = 200) matched in time, without an NMSI...

Cleft lip with or without cleft palate is the most common congenital malformation of the head and the third-most common birth defect. Surgical repair of the lip is the only treatment and is usually performed during the first year of life. Hypertrophic scar (HTS) formation is a frequent postoperative complication that impairs soft tissue form, function, or movement. Multiple lip revision operations are often required throughout childhood, attempting to optimize aesthetics and function. The mechanisms guiding HTS formation are multifactorial and complex...

The present study is the application of a two-state model formerly developed by Bicout, D.J. and and Zaccai, G., Biophys J 2001, 80 (3), 1115-23 1 to describe the dynamical transition exhibited in the atomic mean square displacements of biological samples in terms of dynamic and thermodynamic parameters. Data were obtained by elastic incoherent neutron scattering on 1,2-dimyristoyl-sn-glycero-3-phosphocholine lipid membranes in various hydration states and on one partially per-deuterated lipid membrane. Fitting the data with the model allowed investigating which parts of lipid molecules were mainly involved in the dynamical transition, heads, tails or both...

Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin family of growth factors that was first known as responsible for sustain the growth, function and plasticity of neural cells. BDNF exerts its effects by binding to the tyrosine kinase receptor B (TrkB). The BDNF/TrkB axis has been reported to be overexpressed in several neurogenic and non-neurogenic tumors. Its higher expression was associated with a poor prognosis to patients affected by different human malignancies, tumor growth, invasion and metastasis; epithelial-mesenchymal transition (EMT) and resistance to chemotherapy...

OBJECTIVE: We hypothesized that low molecular weight heparin (LMWH) is superior to unfractionated heparin (UH) for venous thromboembolism (VTE) prophylaxis in patients with severe traumatic brain injuries (TBI). SUMMARY BACKGROUND DATA: Pharmacological VTE prophylaxis with LMWH or UH is the current standard of care in TBI. Clinical work suggests that LMWH may be more effective than UH for VTE prophylaxis in trauma patients. Experimental work shows that heparinoids may have neuroprotective properties...

Programmed death-1-directed (PD-1-directed) immune checkpoint blockade results in durable antitumor activity in many advanced malignancies. Recent studies suggest that IFN-γ is a critical driver of programmed death ligand-1 (PD-L1) expression in cancer and host cells, and baseline intratumoral T cell infiltration may improve response likelihood to anti-PD-1 therapies, including pembrolizumab. However, whether quantifying T cell-inflamed microenvironment is a useful pan-tumor determinant of PD-1-directed therapy response has not been rigorously evaluated...

BACKGROUND: Current outcome measures used in upper limb myoelectric prosthesis studies include clinical tests of function and self-report questionnaires on real-world prosthesis use. Research in other cohorts has questioned both the validity of self-report as an activity assessment tool and the relationship between clinical functionality and real-world upper limb activity. Previously,(1) we reported the first results of monitoring upper limb prosthesis use. However, the data visualisation technique used was limited in scope...

BACKGROUND: Most trials in head and neck cancer emphasize locoregional control, as this is the main pattern of therapy failure. However, up to 15% of patients develop distant metastases. The purpose of this study was to present the investigated factors associated with distant metastasis in a single-center patient cohort. METHODS: A retrospective analysis of a single-center patient cohort over an 18-year period has been performed. We report on prevalence and incidence of distant metastasis, timing in relation to locoregional failure, Kaplan-Meier analysis for actuarial distant control rates, and univariate analysis taking into account histological, etiologic, surgical, site-dependent, stage-dependent characteristics, modality of primary therapy, and locoregional control...

Psoriasis is a chronic immune-mediated inflammatory skin disease in which the alteration of the interleukin-23 (IL-23)/IL-17 cytokine axis appears to be crucial from a pathogenetic perspective. This has been confirmed by the efficacy of monoclonal antibodies blocking IL-17A, such as secukinumab and ixekizumab. Brodalumab is a human anti-IL-17 receptor A (IL-17RA) monoclonal antibody that inhibits the biological activity of IL-17A, IL-17F and other IL-17 isoforms, and has been approved (210 mg s.c. at weeks 0, 1, 2 and every 2 weeks thereafter) for the treatment of psoriasis vulgaris, psoriatic arthritis, pustular psoriasis and psoriatic erythroderma in Japan (Lumicef)...
