An overview of viral oncology in Italy - report from the Pavia meeting on solid tumors
Full text linkAbstract This is a report on some of the research activities currently ongoing in Italy as outlined at the “Viruses and solid tumors” meeting jointly organized by the Oncology Sections of IRCCS Policlinico “San Matteo” (Pavia) and IRCCS National Cancer Institute (Aviano), held in Pavia, Italy, on October 2011. Experts from the various disciplines involved in the study of the complex relationships between solid tumors and viruses met to discuss recent developments in the field and to report their personal contributions to the specified topics. Secondary end point was to establish a multidisciplinary work group specifically devoted to solid tumors and infectious agents, aimed to identify areas of common interest, promoting and establishing collaborative projects and programs, and to coordinate clinical and research activities. The group, which will be named IVOG (Italian Viral Oncology Group), will operate under the patronage of the various scientific societies of interest.</p
Hepatocellular carcinoma: beyond the boundaries of age
No full textHepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide, and the management of HCC has radically changed in recent years. Over the last few years, many elderly patients have been considered less amenable to effective treatments compared to younger patients, due to the accumulation of different diseases during their lives. This assumption has now been reviewed and some key points have been outlined such as the necessity of a careful selection of patients, which may lead to satisfactory results after the treatment of elderly patients with HCC. The purpose of this study was to make a comprehensive analysis of results from the literature concerning the multimodal treatment of HCC in elderly patients, analyzing the therapeutic options such as liver resection, ablative treatments, liver transplantation and targeted chemotherapy
Oxygen-ozone (O2-O3) immunoceutical therapy for patients with COVID-19. Preliminary evidence reported
No full textObjective: This study evaluated the potential efficacy of a novel approach to treat COVID-19 patients, using an oxygen-ozone (O2-O3) mixture, via a process called Oxygen-Ozone- Immunoceutical Therapy. The methodology met the criteria of a novel, promising approach to treat successfully elderly COVID-19 patients, particularly when hospitalized in intensive care units (ICUs) Experimental design: We investigated the therapeutic effect of 4 cycles of O2-O3 in 50 hospitalized COVID-19 subjects suffering from acute respiratory disease syndrome (ARDS), aged more than 60 years, all males and undergoing non invasive mechanical ventilation in ICUs. Results: Following O2-O3 treatment a significant improvement in inflammation and oxygenation indexes occurred rapidly and within the first 9 days after the treatment, despite the expected 14-20 days. A significant reduction of inflammatory and thromboembolic markers (CRP, IL-6, D-dimer) was observed. Furthermore, amelioration in the major respiratory indexes, such as respiratory and gas exchange markers (SatO2%, PaO2/FiO2 ratio), was reported. Conclusion: Our results show that O2-O3 treatment would be a promising therapy for COVID-19 patients. It leads patients to a fast recovery from ARDS via the improvement of major respiratory indexes and blood gas parameters, following a relatively short time of dispensed forced ventilation (about one to two weeks). This study may encourage the scientific community to further investigate and evaluate the proposed method for the treatment of COVID-19 patients
Onco-surgical management of colo-rectal liver metastases in older patients: a new frontier in the 3rd millennium
No full textColorectal cancer (CRC) is one the most common malignant tumors in industrialized countries today. Over half of all cancers are currently diagnosed in elderly patients, and 76% of all colorectal cancer patients are diagnosed between 65 and 85 years old. Elderly patients are less likely to undergo curative surgery, and less likely to be offered the option of metastasectomy when colorectal liver metastases (CLM) are present. Hepatic resection has become the standard care for the treatment of isolated CLM. However, in studies reporting resection of CLM only 8-20% of the patients are older than 70 years. When balancing the benefits of surgical resection of liver metastases against the potential risks of surgery, many clinicians are still reluctant to advise in favor of surgical treatment in the elderly. Factors other than age should also be considered when evaluating surgical risk in the elderly, for example, conditions such as heart disease and diabetes have been shown to induce life-threatening postoperative complications. Age alone need not be a contraindication to aggressive surgical therapy in this group, rather, appropriate selection criteria based on tumor characteristics and general medical fitness, similar to those used for younger patients, should be applied

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
