Abstract
The complement system (CS) contributes to the initial containment of viral and bacterial pathogens and clearance of dying cells in circulation. We previously reported mice deficient in complement component 3 (C3KO mice) were more sensitive than wild-type (WT) mice to ocular HSV-1 infection, as measured by a reduction in cumulative survival and elevated viral titers in the nervous system but not the cornea between days three and seven post infection (pi). The present study was undertaken to determine if complement deficiency impacted virus replication and associated changes in inflammation at earlier time points in the cornea. C3KO mice were found to possess significantly (p < 0.05) less infectious virus in the cornea at 24 h pi that corresponded with a decrease in HSV-1 lytic gene expression at 12 and 24 h pi compared to WT animals. Flow cytometry acquisition found no differences in the myeloid cell populations residing in the cornea including total macrophage and neutrophil populations at 24 h pi with minimal infiltrating cell populations detected at the 12 h pi time point. Analysis of cytokine and chemokine content in the cornea measured at 12 and 24 h pi revealed that only CCL3 (MIP-1α) was found to be different between WT and C3KO mice with >2-fold increased levels (p < 0.05, ANOVA and Tukey's post hoc t-test) in the cornea of WT mice at 12 h pi. C3KO mouse resistance to HSV-1 infection at the early time points correlated with a significant increase in type I interferon (IFN) gene expression including IFN-α1 and IFN-β and downstream effector genes including tetherin and RNase L (p < 0.05, Mann-Whitney rank order test). These results suggest early activation of the CS interferes with the induction of the type I IFN response and leads to a transient increase in virus replication following corneal HSV-1 infection.

Abstract
Ocular pathology is often associated with acute herpes simplex virus (HSV)-1 infection of the cornea in mice. The present study was undertaken to determine the role of early T lymphocyte activation 1 protein or osteopontin (OPN) in corneal inflammation and host resistance to ocular HSV-1 infection. C57BL/6 wild type (WT) and osteopontin deficient (OPN KO) mice infected in the cornea with HSV-1 were evaluated for susceptibility to infection and cornea pathology. OPN KO mice were found to possess significantly more infectious virus in the cornea at day 3 and day 7 post infection compared to infected WT mice. Coupled with these findings, HSV-1-infected OPN KO mouse corneas were found to express less interferon (IFN)-α1, double-stranded RNA-dependent protein kinase, and RNase L compared to infected WT animals early post infection that likely contributed to decreased resistance. Notably, OPN KO mice displayed significantly less corneal opacity and neovascularization compared to WT mice that paralleled a decrease in expression of vascular endothelial growth factor (VEGF) A within 12 hr post infection. The change in corneal pathology of the OPN KO mice aligned with a decrease in total leukocyte infiltration into the cornea and specifically, in neutrophils at day 3 post infection and in macrophage subpopulations including CCR2+CD115+CD206+ and CD115+CD183+CD206+ -expressing cells. The infiltration of CD4+ and CD8+ T cells into the cornea was unaltered comparing infected WT to OPN KO mice. Likewise, there was no difference in the total number of HSV-1-specific CD4+ or CD8+ T cells found in the draining lymph node with both sets functionally competent in response to virus antigen comparing WT to OPN KO mice. Collectively, these results demonstrate OPN deficiency directly influences the host innate immune response to ocular HSV-1 infection reducing some aspects of inflammation but at a cost with an increase in local HSV-1 replication.

Abstract
The neonatal Fc receptor (FcRn) is constitutively expressed in the cornea and is up-regulated in response to herpes simplex virus type 1 (HSV-1). Previously, we found targeting cornea FcRn expression by small interfering RNA-mediated knockdown reduced the local efficacy of HSV-1 0ΔNLS vaccinated C57BL/6 mice against ocular challenge with HSV-1. The current study was undertaken to evaluate the HSV-1 0ΔNLS vaccine efficacy in FcRn deficient (FcRn KO) mice challenged with HSV-1. Whereas there was little neutralizing antibody detected in the serum of HSV-1 0ΔNLS vaccinated FcRn KO mice, these mice exhibited the same degree of protection against ocular challenge with HSV-1 as wild type (WT) C57BL/6 mice as measured by cumulative survival, infectious virus shed or retained in tissue, and corneal pathology including opacity and neovascularization. Mock-vaccinated FcRn KO mice were found to be more sensitive to ocular HSV-1 infection compared to mock-vaccinated (WT) mice in terms of cumulative survival and virus shedding. In addition, the FcRn KO mice generated significantly fewer effector (CD3+CD44+CD62L-) and central (CD3+CD44+CD62L+) memory CD8+ T cells compared to the WT mice 7 days post infection. Collectively, mock-vaccinated FcRn KO mice are susceptible to ocular HSV-1 infection but HSV-1 0ΔNLS vaccinated FcRn KO mice are resistant suggesting that in addition to the FcRn, other pathways are involved in mediating the protective effect of the HSV-1 0ΔNLS vaccine against subsequent HSV-1 challenge.

Abstract
The contribution of T cell and antibody responses following vaccination in resistance to herpes simplex virus 1 (HSV-1) infection continues to be rigorously investigated. In the present article, we explore the contribution of CD8+ T cells specific for the major antigenic epitope for HSV-1 glycoprotein B (gB498-505, gB) in C57BL/6 mice using a transgenic mouse (gBT-I.1) model vaccinated with HSV-1 0ΔNLS. gBT-I.1-vaccinated mice did not generate a robust neutralization antibody titer in comparison to the HSV-1 0ΔNLS-vaccinated wild-type C57BL/6 counterpart. Nevertheless, the vaccinated gBT-I.1 mice were resistant to ocular challenge with HSV-1 compared to vehicle-vaccinated animals based on survival and reduced corneal neovascularization but displayed similar levels of corneal opacity. Whereas there was no difference in the virus titer recovered from the cornea comparing vaccinated mice, HSV-1 0ΔNLS-vaccinated animals possessed significantly less infectious virus during acute infection in the trigeminal ganglia (TG) and brain stem compared to the control-vaccinated group. These results correlated with a significant increase in gB-elicited interferon-γ (IFN-γ), granzyme B, and CD107a and a reduction in lymphocyte activation gene 3 (LAG-3), programmed cell death 1 (PD-1), and T cell immunoglobulin and mucin domain-containing protein 3 (TIM-3) expressed by TG infiltrating gB-specific CD8+ T cells from the HSV-1 0ΔNLS-vaccinated group. Antibody depletion of CD8+ T cells in HSV-1 0ΔNLS-vaccinated mice rendered animals highly susceptible to virus-mediated mortality similar to control-vaccinated mice. Collectively, the HSV-1 0ΔNLS vaccine is effective against ocular HSV-1 challenge, reducing ocular neovascularization and suppressing peripheral nerve virus replication in the near absence of neutralizing antibody in this unique mouse model.IMPORTANCE The role of CD8+ T cells in antiviral efficacy using a live-attenuated virus as the vaccine is complicated by the humoral immune response. In the case of the herpes simplex virus 1 (HSV-1) 0ΔNLS vaccine, the correlate of protection has been defined to be primarily antibody driven. The current study shows that in the near absence of anti-HSV-1 antibody, vaccinated mice are protected from subsequent challenge with wild-type HSV-1 as measured by survival. The efficacy is lost following depletion of CD8+ T cells. Whereas increased survival and reduction in virus replication were observed in vaccinated mice challenged with HSV-1, cornea pathology was mixed with a reduction in neovascularization but no change in opacity. Collectively, the study suggests CD8+ T cells significantly contribute to the host adaptive immune response to HSV-1 challenge following vaccination with an attenuated virus, but multiple factors are involved in cornea pathology in response to ocular virus challenge.

Abstract
The protective efficacy of a live-attenuated HSV type 1 (HSV-1) vaccine, HSV-1 0∆ nuclear location signal (NLS), was evaluated in mice prophylactically in response to ocular HSV-1 challenge. Mice vaccinated with the HSV-1 0∆NLS were found to be more resistant to subsequent ocular virus challenge in terms of viral shedding, spread, the inflammatory response, and ocular pathology in a dose-dependent fashion. Specifically, a strong neutralizing Ab profile associated with low virus titers recovered from the cornea and trigeminal ganglia was observed in vaccinated mice in a dose-dependent fashion with doses ranging from 1 × 103 to 1 × 105 PFU HSV-1 0∆NLS. This correlation also existed in terms of viral latency in the trigeminal ganglia, corneal neovascularization, and leukocyte infiltration and expression of inflammatory cytokines and chemokines in infected tissue with the higher doses (1 × 104-1 × 105 PFU) of the HSV-1 0∆NLS-vaccinated mice, displaying reduced viral latency, ocular pathology, or inflammation in comparison with the lowest dose (1 × 103 PFU) or vehicle vaccine employed. Fifteen HSV-1-encoded proteins were uniquely recognized by antisera from high-dose (1 × 105 PFU)-vaccinated mice in comparison with low-dose (1 × 103 PFU)- or vehicle-vaccinated animals. Passive immunization using high-dose-vaccinated, but not low-dose-vaccinated, mouse sera showed significant efficacy against ocular pathology in HSV-1-challenged animals. In summary, we have identified the minimal protective dose of HSV-1 0∆NLS vaccine in mice to prevent HSV-mediated disease and identified candidate proteins that may be useful in the development of a noninfectious prophylactic vaccine against the insidious HSV-1 pathogen.

Abstract
Purpose Corneal opacity and neovascularization (NV) are often described as outcomes of severe herpes simplex virus type 1 (HSV-1) infection. The current study investigated the role of colony-stimulating factor 1 receptor (CSF1R)+ cells and soluble factors in the progression of HSV-1-induced corneal NV and opacity. Methods MaFIA mice were infected with 500 plaque-forming units of HSV-1 in the cornea following scarification. From day 10 to day 13 post-infection (pi), mice were treated with 40 µg/day of AP20187 (macrophage ablation) or vehicle intraperitoneally. For osteopontin (OPN) neutralization experiments, C57BL/6 mice were infected as above and treated with 2 µg of goat anti-mouse OPN or isotypic control IgG subconjunctivally every 2 days from day 4 to day 12 pi. Mice were euthanized on day 14 pi, and tissue was processed for immunohistochemistry to quantify NV and opacity by confocal microscopy and absorbance or detection of pro- and anti-angiogenic and inflammatory factors and cells by suspension array analysis and flow cytometry, respectively. Results In the absence of CSF1R+ cells, HSV-1-induced blood and lymphatic vessel growth was muted. These results correlated with a loss in fibroblast growth factor type 2 (FGF-2) and an increase in OPN expression in the infected cornea. However, a reduction in OPN expression in mice did not alter corneal NV but significantly reduced opacity. Conclusions Our data suggest that CSF1R+ cell depletion results in a significant reduction in HSV-1-induced corneal NV that correlates with the loss of FGF-2 expression. A reduction in OPN expression was aligned with a significant drop in opacity associated with reduced corneal collagen disruption.

Abstract
Aging and female sex are the strongest risk factors for nontraumatic osteoarthritis (OA); whereas obesity is a modifiable risk factor accelerating OA. Prior studies indicate that the innate immune receptor toll-like receptor 4 (TLR4) mediates obesity-induced metabolic inflammation and cartilage catabolism via recognition of damage-associated molecular patterns and is increased with aging in OA joints. TLR4 responses are limited by innate immunoreceptor adapter protein DNAX-activating protein of 12kDA (DAP12). We undertook this study to test the hypothesis that TLR4 promotes, whereas DAP12 limits, obesity-accelerated OA in aged female mice. We fed 13- to 15-month-old female WT, TLR4 KO, and DAP12 KO mice a high-fat diet (HFD) or a control diet for 12 weeks, and changes in body composition, glucose tolerance, serum cytokines, and insulin levels were compared. Knee OA was evaluated by histopathology and μCT. Infrapatellar fat pads (IFPs) were analyzed by histomorphometry and F4/80+ crown-like structures were quantified. IFPs and synovium gene expression were analyzed using a targeted insulin resistance and inflammation array. All HFD-treated mice became obese, but only WT and TLR4 KO mice developed glucose intolerance. HFD induced cartilage catabolism in WT and DAP12 KO female mice, but not in TLR4 KO mice. Gene-expression analysis of IFPs and synovium showed significant differences in insulin signaling, adipokines, and inflammation between genotypes and diets. Unlike young mice, systemic inflammation was not induced by HFD in the older female mice independent of genotype. Our findings support the conclusion that TLR4 promotes and DAP12 limits HFD-induced cartilage catabolism in middle-aged female mice.

Abstract
NEW FINDINGS What is the central question of this study? What is the effect of chronic intermittent low-level transcutaneous vagus nerve stimulation on cardiac inflammation, fibrosis and diastolic dysfunction in a rat model of heart failure with preserved ejection fraction? What is the main finding and its importance? In salt-sensitive rats fed with high salt diet, low-level transcutaneous vagus nerve stimulation significantly attenuated blood pressure elevation, ameliorated diastolic function, and attenuated left ventricular inflammation and fibrosis compared to the sham group. Further studies to examine the efficacy of this novel treatment in humans are warranted. ABSTRACT Inflammation and fibrosis play a central role in the development of heart failure with preserved ejection fraction (HFpEF). We previously showed that low-level, transcutaneous stimulation of the vagus nerve at the tragus (LLTS) is anti-inflammatory. We investigated the effect of chronic intermittent LLTS on cardiac inflammation, fibrosis and diastolic dysfunction in a rat model of HFpEF. Dahl salt-sensitive (DS) rats were randomized in three groups: low salt (LS, 0.3% NaCl; n = 12; control group without stimulation) and high salt (HS, 4% NaCl) with either active (n = 18) or sham (n = 18) LLTS at 7 weeks of age. After 6 weeks of diet (baseline), sham or active LLTS (20 Hz, 2 mA, 0.2 ms) was implemented for 30 min daily for 4 weeks. Echocardiography was performed at baseline and 4 weeks after treatment (endpoint). At endpoint, left ventricle (LV) histology and gene expression were examined. After 6 weeks of diets, HS rats developed hypertension and LV hypertrophy compared to LS rats. At endpoint, LLTS significantly attenuated blood pressure elevation, prevented the deterioration of diastolic function and improved LV circumferential strain, compared to the HS sham group. LV inflammatory cell infiltration and fibrosis were attenuated in the HS active compared to the HS sham group. Pro-inflammatory and pro-fibrotic genes (tumour necrosis factor, osteopontin, interleukin (IL)-11, IL-18 and IL-23A) were differentially altered in the two groups. Chronic intermittent LLTS ameliorates diastolic dysfunction, and attenuates cardiac inflammation and fibrosis in a rat model of HFpEF, suggesting that LLTS may be used clinically as a novel non-invasive neuromodulation therapy in HFpEF.

Abstract
A survey was conducted on 84 patients who chose to have breast reconstruction after mastectomy. A self-rating questionnaire was sent to each patient by mail to collect as much information about the patient as possible: individual status, reasons for requesting breast reconstruction, acceptance and advantages of having the new breast, satisfaction with the overall esthetic results, amount of patient information regarding breast reconstruction, and the source of this information. Once the questionnaire was completely filled out, it was returned by mail to the persons conducting this study. Fourty-three patients (51% of sample) replied with a completed questionnaire. When all the data for this survey were collected, an interesting factor emerged: 33 patients (76.7% of those who replied) reported being substantially satisfied with the esthetic results of their operation. When asked about the reasons for requesting breast reconstruction, 16 patients asserted their request was based on the desire to prove to themselves that they had overcome the disease, and 16 to improve body image. When asked about the advantages of breast reconstruction, 17 patients believed the operation would help improve inner feelings about the loss of the breast. Thus breast reconstruction is indeed an element of prime importance to mastectomized women, especially for their physical and psychological rehabilitation.

Abstract
PURPOSE OF THE REVIEW Mounting evidence supports a role of low-grade inflammation in the pathophysiology of osteoarthritis (OA). We review and discuss the role of synovitis, complement activation, cytokines, and immune cell population in OA. RECENT FINDINGS Using newer imaging modalities, synovitis is found in the majority of knees with OA. Complement activation and pro-inflammatory cytokines play a significant role in the development of cartilage destruction and synovitis. Immune cell infiltration of OA synovial tissue by sub-populations of T cells and activated macrophages correlates with OA disease progression and pain. The innate and acquired immune system plays a key role in the low-grade inflammation found associated with OA. Targets of these pathways my hold promise for future disease-modifying osteoarthritis drugs (DMOADs).

Abstract
In recent years, there has been an explosion in the amount of available information on cancer in parallel with an ever-increasing number of cancer survivors. Cancer patients and long-term survivors are known to be more sensitive to health-related information and dietary changes could represent a potential consequence of this huge availability of messages. In our review about dietary changes after cancer diagnosis, we found that this topic is particularly investigated among the breast cancer population. The literature examined show that breast cancer patients modify their eating habits after diagnosis in a percentage that varies between approximately 30% and 60%. The most reported changes were an increased consumption of fruit and vegetables, a decrease in the consumption of red meat, fats and sugary foods. Patients who reported changes were more likely to be younger, with higher educational levels and with a longer period of time since their diagnosis of cancer. It also emerged that cancer patients are often more likely to use supplements. This topic has not been investigated in cancer patients in Italy, therefore, we propose an approach to explore it with a structured questionnaire: The "ECHO SURVEY - Eating habits CHanges in Oncologic patients".

Abstract
The efficiency and type of pathway chosen to repair DNA double-strand breaks (DSBs) are critically influenced by the nucleosome packaging and the chromatin architecture surrounding the DSBs. The Swi/Snf (PBAF and BAF) chromatin-remodeling complexes contribute to DNA damage-induced nucleosome remodeling, but the mechanism by which it contributes to this function is poorly understood. Herein, we report how the Baf200 (Arid2) PBAF-defining subunit regulates DSB repair. We used cytological and biochemical approaches to show that Baf200 plays an important function by facilitating homologous recombination-dependent processes, such as recruitment of Rad51 (a key component of homologous recombination) to DSBs, homology-directed repair, and cell survival after DNA damage. Furthermore, we observed that Baf200 and Rad51 are present in the same complex and that this interaction is mediated by C-terminal sequences in both proteins. It has been recognized previously that the interplay between distinct forms of Swi/Snf has profound functional consequences, but we understand little about the composition of complexes formed by PBAF protein subunits. Our biochemical analyses reveal that Baf200 forms at least two distinct complexes. One is a canonical form of PBAF including the Swi/Snf-associated Brg1 catalytic subunit, and the other contains Baf180 but not Brg1. This distinction of PBAF complexes based on their unique composition provides the foundation for future studies on the specific contributions of the PBAF forms to the regulation of DNA repair.

Abstract
Continuing medical education (CME) is now one of the key areas of development in medical education. This paper describes the development of an intramural continuing medical education programme de novo in a newly opened cancer institute in Italy, which provided a unique opportunity to study attitudes towards the concepts and goals of continuing medical education as most of the individuals involved in this programme were exposed to continuing medical education for the first time. The continuing medical education programme was overseen by a CME committee for 1 year. Three 1-hour sessions were delivered each week and one credit point was awarded for each session. The sessions included grand rounds, clinical-based teaching and a 3-weekly rotating schedule of pathology, radiology and research. Participants were all the medical doctors attending the European Institute of Oncology. Attendance at greater than 50% of the total sessions available yearly qualified the individual for certification by the CME committee of the Institute. A questionnaire was circulated to all medical doctors at the Institute at the end of the academic year to assess attitudes to CME in general. Forty-six out of 84 questionnaires were returned. The majority of those involved in this CME intramural programme undertook self-directed CME activities and at least 50% had not previously attended either grand rounds or research seminars. Most felt that CME should not be mandatory but that its activities should be monitored. The greatest difficulty with CME was in its timing.

Abstract
Cancer patients may commit suicide at any stage of the disease and many risk factors of suicide have been described in the literature. To identify the possible vulnerability factors of suicide in five terminal cancer patients who committed suicide while they were cared for at home by well-trained palliative care teams, a psychological autopsy study was carried out by reviewing their medical records; their report of symptoms at the time of care; and with the caregivers', doctors', and nurses' recollection of events by means of a structured interview prepared ad hoc. We collected data regarding the physical, emotional, and social suffering of the patients, their personality profile, and their feelings with respect to the illness and disability. The interviews lasted for a mean of two hours and were performed from 2-8 years after the suicide events by the social worker at the Rehabilitation and Palliative Care Division. The interviews took place between June 1996 and January 1998. All the patients showed great concern about the lack of autonomy and independence, refused dependence on others and had fear/worry of losing their autonomy. Four patients presented functional and physical impairments, uncontrolled pain, awareness of being in the terminal stage, and mild to moderate depression. They had a feeling of hopelessness consequent to their clinical conditions, fear of suffering, and feeling of being a burden on others. They had a strong character and managerial professions. They had isolated themselves from others and they had previously talked about suicide. Before committing suicide, three patients had adverse physical/emotional consequences to the oncological treatments-they showed aggressiveness towards their family and one towards the home care physician. Multiple vulnerability factors were present simultaneously in all patients. However, the loss of, and the fear of losing, autonomy and their independence and of being a burden on others were the most relevant. The identification of a cancer patient at risk of committing suicide forms the first step for the prevention of and the setting up of adequate psychosocial rehabilitation of these patients whenever possible.

Abstract
Patients with terminal cancer are thought to be at high risk of committing suicide. In a population of 17,964 patients with terminal cancer cared for at home by 12 palliative-care teams, five patients committed suicide. We speculate that continuing care made up by symptomatic treatment and psychosocial support given to these patients may reduce the risk.

Abstract
BACKGROUND Despite the large amount of data available about the EORTC QLQ-C30 questionnaire, there have been very few studies focussed on long-survival cancer patients, and no data are available on its performance in the Italian setting. PATIENTS AND METHODS Within the framework of a project aimed at evaluating the characteristics of available HR-QOL questionnaires in the Italian language, the EORTC QLQ-C30 questionnaire together with the Short Form 36-item Health Survey (SF-36) were mail-administered to a sample of patients previously recruited in two large multicenter randomized clinical trials on early breast and colon cancers. The properties of the questionnaire were evaluated using standard psychometric techniques and correlation analyses with demographic and clinical independent variables. RESULTS In the sample of patients who sent back the questionnaires under evaluation, the EORTC QLQ-C30 showed satisfactory acceptability (response rate = 64% and very low prevalence of missing at item and scale level), and the psychometric analyses confirmed the multi-dimensional conceptualisation in terms of convergent and discriminant validity. Moreover, EORTC QLQ-C30 scales showed substantial correlation with the homologous SF-36 scales. Few socio-demographic (age, gender, schooling) and clinical (type of cancer disease) variables were associated with HR-QOL. Breast cancer patients reported, on average, worse physical health-related scores, but after adjustment for age and education, most of the differences disappeared. CONCLUSIONS These findings confirm the validity and robustness of the EORTC QLQ-C30 in this sample of long-survival Italian cancer patients. Further ad hoc validation studies are required to evaluate its significance in these particular patients.

Abstract
In recent times there have been many important changes in the surgical management of rectal cancer. The general thrust of these changes has been towards a less invasive approach with preservation of intestinal continuity and avoidance of the psychological sequelae of a stoma. It is also becoming increasingly apparent that profound sexual and autonomic dysfunction can be associated with abdominoperineal resection. This paper highlights these issues and the conflict between performing an adequate oncological procedure and reducing the incidence of postoperative psychological morbidity. It outlines the great changes there have been in surgical technique and their relevance to psychological problems after surgery for rectal cancer. The need for auditing psychological morbidity when assessing the outcome of surgical series is emphasised, as is the importance of involving the patient in the medical decision making.

Abstract
This study investigated the Psychosocial adjustment in 40 patients who received orthotopic liver transplantation (OLT) for several endstage liver diseases. Twenty patients were grafted because they suffered from liver Cancer as well as cirrhosis. Particular attention was paid to evaluating whether cancer could affect recipients' coping with transplant. Each patient underwent a semi-structured interview to obtain information on their psychosocial life, relationship with the donor, organ acceptance and life expectancy. Interview was performed I year after transplantation. A psychodiagnostic evaluation was also performed using a Minnesota Multiphasic Personality Inventory (MMPI) and a Human Figure Test. Psychosocial adaptation in everyday life following liver transplantation seemed good in most of the patients, whatever the indication for transplantation might be. It can he seen that by replacing the diseased organ a high percentage of oncological patients overcame their fear of cancer.

Abstract
Whether a terminally ill cancer patient should be actively fed or simply hydrated through subcutaneous or intravenous infusion of isotonic fluids is a matter of ongoing controversy among clinicians involved in the care of these patients. Under the auspices of the European Association for Palliative Care, a committee of experts developed guidelines to help clinicians make a reasonable decision on what type of nutritional support should be provided on a case-by-case basis. It was acknowledged that part of the controversy related to the definition of the terminal cancer patient, since this is a heterogeneous group of patients with different needs, expectations, and potential for a medical intervention. A major difficulty is the prediction of life expectancy and the patient's likely response to vigorous nutritional support. In an attempt to reach a decision on the type of treatment support (artificial nutrition vs. hydration) which would best meet the needs and expectations of the patient, we propose a three-step process: Step 1: define the eight key elements necessary to reach a decision; Step II: make the decision; and Step III: reevaluate the patient and the proposed treatment at specified intervals. Step I involves assessing the patient concerning the following: 1) oncological/clinical condition; 2) symptoms; 3) expected length of survival; 4) hydration and nutritional status; 5) spontaneous or voluntary nutrient intake; 6) psychological profile; 7) gut function and potential route of administration; and 8) need for special services based on type of nutritional support prescribed. Step II involves the overall assessment of pros and cons, based on information determined in Step I, in order to reach an appropriate decision based on a well-defined end point (i.e., improvement of quality of life; maintaining patient survival; attaining rehydration). Step III involves the periodic reevaluation of the decision made in Step II based on the proposed goal and the attained result.

Abstract
Impotency due to parasympathetic nerve injury is one of the most feared consequences of rectal cancer surgery. Sexual relationships make a significant contribution to the quality of life for almost everybody. Rectal excision and coloanal anastomosis (CAA) is a new surgical procedure for low rectal tumor with little data regarding the prevalence of sexual impairment as yet. We have examined the sexual life of 21 male patients who have undergone CAA by means a self-administered questionnaire. Only two patients reported reactive impotency. On the other hand 17 out of 21 patients had no ejaculation after undergoing surgery. According to our data it appears that CAA results in surgery a low degree of sexual impairment (impotency). Both sexual dysfunction and quality of life investigations should be integrated with oncological results when reporting data about colorectal surgery.

Abstract
Rectal cancer incidence is increasing among the elderly who are more often considered for palliation rather than for surgical cure. Moreover, sphincter-sparing surgery is often avoided when treating the elderly. We report our experience on a consecutive series of 38 subjects, suffering from a lower third rectal tumour with a median distance of 5.6 cm from the anal verge (7 Dukes' A, 6 Dukes' B, 17 Dukes' C, 3 Dukes' D, 3 anastomotic recurrences and 2 large villous adenomas). All subjects were prospectively collected in a 2-year period and treated with total resection and colo-anal hand-sewn anastomosis on a J colic reservoir. 20 patients younger than 65 years and 18 over 65 years were matched for surgical complications, late morbidity, oncological and functional results but no statistical difference was found. Our hope is that a conservative approach in treating the low rectal tumours will progressively be accepted for elderly patients.

Abstract
Genital human papillomavirus (HPV) infection can lead to self-inflicted blame and hypochondriac fears as well as to problems with sexuality. The aim of this study was to assess the psychological and psychodynamic aspects of patients with widespread genital HPV infection entering into a clinical trial in which they were randomly assigned to three treatment groups: CO2 laser ablation, intramuscular interferon-alpha, CO2 laser ablation plus intramuscular interferon-alpha. Fifty-one patients were studied. Patients were asked to take a series of questionnaires which included a self-rating questionnaire for gathering information on sexuality, emotional relationship with the partner and social life. A visual analog scale was used to rate intensity of pain during sexual intercourse. Each patient went also through an in-depth interview with a clinical psychologist and filled out two personality tests to measure depression (CDQ = IPAT depression test) and anxiety (ASQ = IPAT anxiety test). Results indicated a high percentage of sexual impairments after therapy (28 cases), presence of fear of cancer (14 cases) and worsenings in the emotional relationship with the partner. No difference was found among groups of treatment.

Abstract
BACKGROUND In 1986, the European Organization for Research and Treatment of Cancer (EORTC) initiated a research program to develop an integrated, modular approach for evaluating the quality of life of patients participating in international clinical trials. PURPOSE We report here the results of an international field study of the practicality, reliability, and validity of the EORTC QLQ-C30, the current core questionnaire. The QLQ-C30 incorporates nine multi-item scales: five functional scales (physical, role, cognitive, emotional, and social); three symptom scales (fatigue, pain, and nausea and vomiting); and a global health and quality-of-life scale. Several single-item symptom measures are also included. METHODS The questionnaire was administered before treatment and once during treatment to 305 patients with nonresectable lung cancer from centers in 13 countries. Clinical variables assessed included disease stage, weight loss, performance status, and treatment toxicity. RESULTS The average time required to complete the questionnaire was approximately 11 minutes, and most patients required no assistance. The data supported the hypothesized scale structure of the questionnaire with the exception of role functioning (work and household activities), which was also the only multi-item scale that failed to meet the minimal standards for reliability (Cronbach's alpha coefficient > or = .70) either before or during treatment. Validity was shown by three findings. First, while all interscale correlations were statistically significant, the correlation was moderate, indicating that the scales were assessing distinct components of the quality-of-life construct. Second, most of the functional and symptom measures discriminated clearly between patients differing in clinical status as defined by the Eastern Cooperative Oncology Group performance status scale, weight loss, and treatment toxicity. Third, there were statistically significant changes, in the expected direction, in physical and role functioning, global quality of life, fatigue, and nausea and vomiting, for patients whose performance status had improved or worsened during treatment. The reliability and validity of the questionnaire were highly consistent across the three language-cultural groups studied: patients from English-speaking countries, Northern Europe, and Southern Europe. CONCLUSIONS These results support the EORTC QLQ-C30 as a reliable and valid measure of the quality of life of cancer patients in multicultural clinical research settings. Work is ongoing to examine the performance of the questionnaire among more heterogenous patient samples and in phase II and phase III clinical trials.

Abstract
We examined the impact of testis cancer and its curative therapies on the outlook of life, working activity, partner relationship and sexual function in 31 consecutive patients 18 to 51 years old (mean age 29.3 years, median 28 years) who already had undergone orchiectomy. Of the patients 13 subsequently were treated with chemotherapy alone, 6 with retroperitoneal lymph node dissection alone, and 7 with chemotherapy and an operation, while 5 seminoma patients were treated with radiotherapy. The patients were examined 3, 6 and 18 months after orchiectomy. Each patient was required to fill out a questionnaire to gather information relative to their work activities, emotional relationship with the partner and sexual life. The patients also completed an assessment form on the quality of life (Spitzer QL-Index) and a series of horizontal analogues to evaluate anxiety, mood, nausea, weakness and general health status. The statistical analysis of the linear and quadratic components for the variables under study was done with the general linear model for block design. Psychosocial adaptability of these patients, regardless of the treatment they underwent, in time became progressively less problematic and the development of psychosocial problems during the long-term adjustment was low. Only 2 patients reported worsening of the emotional relationship with the partner after treatment: 1 underwent chemotherapy and an operation, and 1 underwent radiotherapy. With regard to sexual life, no serious dysfunction was noted apart from the loss of ejaculation in 11 of 13 patients who underwent retroperitoneal lymph node dissection. Of our sample patients who had lost ejaculation only 2 suffered from a high state of anxiety. The anxiety scores on the last completed linear analogue were 2.6 and 4.1, whereas at the same time the mood scores were 1.9 and 4.4. Therefore, it is important for the clinician to assess the psychogenic aspect of this side effect when this type of operation is proposed.

Abstract
One hundred and one patients participating in a phase I study with the synthetic retinoid 4-HPR (4-hydroxyphenyl retinamide) were evaluated. The study was set up by Veronesi et al. during 1986 at the National Cancer Institute of Milan. The patients were randomized into 4 groups of therapy: 25 in the placebo group, 25 in the group receiving a daily dose of 100 mg of HPR, 26 in the group receiving 200 mg/day of HPR, and 25 in the group receiving 300 mg/day of HPR. All patients were previously treated at our Institute for breast cancer. None had received adjuvant therapy, chemotherapy or hormone therapy. After 4-5 months from the beginning of treatment, all patients received a series of tests to evaluate anxiety, depression and sexual life. Moreover, during one the follow-up checkups after 4-5 months, the patients filled-out a self-scoring mood questionnaire. The results did not show any particular differences between the groups, although we found that the administered drug and experimental setting do not interfere with the psychologic state of the participating patients.

Abstract
Sixty male patients surgically treated for colorectal cancer were interviewed by structured questionnaire to evaluate the etiology of sexual dysfunction and quality of life. Patients were divided into three groups: 20 who underwent low anterior resection, 20 subjected to Miles' abdominoperineal amputation, and 20 who underwent high anterior resection. Statistical evaluation of the three groups, by use of the chi-square test and Student's t test, showed that extent of the surgical dissection plays the most important role, although psychologic problems are also involved.
