Touch, threats, and transactions: Pandemic influences on consumer responses and the mediating role of touch likelihood when shopping for fruits and v…
2022
The COVID-19 pandemic has influenced consumer behavior in numerous ways. Most of the public health measures have centered around minimizing social contact and physical touch. In the present study, we investigate the impact of such touch restrictions, introduced during the pandemic, on consumers’ shopping responses and payment preferences in the context of a perishable food category amenable to tactile evaluation (fresh fruits and vegetables). The study used a single-factor between-subjects design (during vs. before the COVID-19 pandemic), with the data collected in a scenario-based online experiment from a sample of 729 participants. The results revealed significantly less favorable shoppin…
Self-Healing of Redundant FLASH ADCs
2022
For the design of high-speed ADCs, the traditional speed-accuracy trade-off can only be solved at the expense of power consumption. Using fast small transistors takes full advantage of technology scaling but induces large amounts of random variability. Redundancy has been proposed as a way to cope with variability in FLASH converter and open the trade-off. The offset of redundant comparators are measured and only the best candidates which have been selected are powered-up. However, the candidate selection is usually carried out in foreground and a lot of silicon area is thus occupied by comparators that will only be used once, during calibration. In this paper we show how such an approach, …
Lymphomas and thyroid: Bridging the gap
2018
The thyroid gland is often involved in the development of neoplastic diseases, including lymphoproliferative disorders. The aim of this paper is to provide a comprehensive overview of the multiple interactions between lymphoma and thyroid. Through an extensive research among the literature, the relationship between lymphomas and thyroid can be established at various levels, and the possible interconnections are here summarized in 5 points: (1) the greater risk of lymphoma development in some thyroid diseases; (2) the primary thyroid lymphoma, with focus on issues related to the diagnosis, differential diagnosis, and treatment; (3) the incidence of thyroid involvement in primitive nodal lymp…
Management of Toxicity Induced by Anti-EGFR Therapy in Metastatic Colorectal Cancer
2013
Use of anti-epidermal growth factor receptor (anti-EGFR) agents has yielded significant advances in the treatment of patients with metastatic colorectal cancer. In fact these drugs, which include the monoclonal antibodies cetuximab and panitumumab, can be delivered both as a single agent and in combination with chemotherapy, achieving better survival and quality of life and in some cases also resectability of metastases. However, these agents can result in the development of toxicities that are usually different from those observed with chemotherapy alone. For the management of these adverse effects, proper knowledge is mandatory. Skin toxicity is the most frequent adverse effect. Other tox…
Open-label, multicentre expansion cohort to evaluate imgatuzumab in pre-treated patients with KRAS-mutant advanced colorectal carcinoma.
2014
Abstract Aim Imgatuzumab (GA201) is a novel anti-epidermal growth factor receptor (anti-EGFR) antibody glycoengineered for enhanced antibody-dependent cell-mediated cytotoxicity (ADCC). We investigated the efficacy of imgatuzumab in patients with EGFR-positive, KRAS -mutant advanced colorectal cancer. Methods Patients received single-agent imgatuzumab (1400 mg on day 1 and 8 followed by q2W) as third line therapy in an open-label, multicentre, non-randomised, expansion study. The primary end-point was tumour response. Pre- and on-treatment biopsies and blood samples were investigated for biomarkers related to imgatuzumab’s believed mechanism of action (MoA). Results 25 patients were treated…
Quality of Life in Patients With Severe Skin Reactions in Course of First-Generation Epidermal Growth Factor Receptor Inhibitors Monoclonal Antibodie…
2021
Background: Metastatic colorectal cancer (mCRC) with wild type expression of RAS and RAF genes can be treated with anti-epidermal growth factor receptor (EGFR) monoclonal antibodies, such as cetuximab, in combination with chemotherapy. Skin toxicity represents the most serious and frequent side effect in these patients. Skin manifestations occur in approximately 80% of patients. In this study, we investigated the consequences on body image and quality of life (QoL) of patients with severe skin toxicity. Methods: One hundred patients were enrolled with mCRC. All patients signed informed consent and completed questionnaires to assess QoL and body discomfort. Toxicity was assessed on Common Te…

e20724 Background: Anti-EGFR empowered chemotherapeutic regimens resulted in increased overall survival (OS) and response rates (RR). Anti-EGFR induced skin rash occurs in ~ 70% patients, and ~18% ...
Final results of the European Advanced Renal Cell Carcinoma Sorafenib (EU-ARCCS) expanded-access study: a large open-label study in diverse community…
2011
Background The European Advanced Renal Cell Carcinoma Sorafenib (EU-ARCCS) expanded-access study provided sorafenib to advanced renal cell carcinoma (RCC) patients in whom previous systemic therapy had failed. The study assessed the safety and use of sorafenib for the treatment of advanced RCC in a large community-based patient population across 11 countries in Europe. Patients and methods EU-ARCCS was a single-arm, open-label trial of sorafenib in advanced RCC patients. End points included safety, time to progression, progression-free survival (PFS), and disease control rate (DCR). Subgroup analyses included age, Eastern Cooperative Oncology Group performance status, histology, prior thera…
A pharmacokinetically (PK) and pharmacodynamically (PD) driven phase I trial of the pan-AKT inhibitor AZD5363 with expansion cohorts in PIK3CA mutant…
2015
Background: AZD5363 is a novel potent pan-AKT inhibitor (IC50of AKT1, AKT2 and AKT3 of 3, 7 and 7nM respectively) with preclinical activity across a range of models. Methods: The trial had an adaptive design that allowed changes in schedule based on toxicity, PK, and PD findings. AZD5363 was administered orally (PO) twice a day (BID). Three schedules were explored: continuous dosing (7/7), four days a week, (4/7) and two days a week (2/7). PD biomarkers including pAKT, pGSK3?, and pPRAS40 were measured by IHC in pre- and post-treatment tumor biopsies. Once a RP2D was established, two expansion cohorts of PIK3CA-mutant ER+ve breast (B) and gynecological (G) cancers were explored. Results: 47…
Phase Ib Trial Trial of Rg7116, a Glycoengineered Monoclonal Antibody Targeting Her3, in Combination with Cetuximab or Erlotinib in Patients with Adv…
2014
ABSTRACT Aim: To evaluate the safety profile of RG7116 in combination with cetuximab or erlotinib. Methods: Patients (pts) with advanced or metastatic carcinomas with centrally confirmed HER3 protein expression were included. RG7116 plus cetuximab (400 mg/m2 followed by 250 mg/m2 qw IV) and RG7116 plus erlotinib (150 mg/day p.o.) combinations were evaluated in a dose escalation study with “3 + 3” design at a starting dose of 400 mg IV of RG7116 in a q2w regimen. Results: Twenty-seven pts were enrolled in 5 cohorts (400 to 2000 mg) in the cetuximab arm. One dose-limiting toxicity (DLT) of grade 3 dehydration was reported in the 800-mg cohort. Twenty-seven pts were enrolled in 4 cohorts (400 …
