Abstract
Background A virtual reality experience (VRE) could represent a viable non-pharmacological intervention to reduce and better manage the main factors of psychophysical distress related to the diagnosis and treatment of cancer. Aim The “Patient’s Dream” study was a two-arm randomized controlled trial conducted at the Regina Elena National Cancer Institute – IRCCS (Rome, Italy) from April 2019 to January 2020 to evaluate VRE impact in patients affected by breast or ovarian cancer. Before starting the first cycle of chemotherapy (CT), patients were randomized to receive the VRE (VRE arm) as “distraction therapy” or to entertain themselves with conventional means (control arm). The primary aims were the assessment of psychological distress, anxiety and quality of life between the two study arms. Secondary endpoints were the perceived time during the first course of CT and the acute and late toxicity. Results Fourty-four patients were enrolled, 22 patients were randomly assigned to the VRE arm and 22 to the control arm. Collected data underline the absence of prevalent disturbs of anxiety and depression in both groups. Nevertheless, even if the state anxiety values before and after CT decreased in both groups, this reduction was statistically significant over time only in the VRE arm. The duration of therapy perceived by patients undergoing distraction therapy was significantly shorter when compared to the control group. The use of VRE during the first CT cycle appeared to reduce asthenia outcomes. Conclusion Obtained data suggest that the VRE positively influenced the levels of state anxiety among cancer patients and support the continuous research on VRE as a distraction intervention, with the aim to meet the clinical need for effective nonpharmacologic adjunctive therapies.

Abstract
Human herpes viruses (HHVs) have been frequently detected in the gastrointestinal (GI) tract and may contribute to the development of gastric cancer. In the present study, the detection rate and viral load of Epstein Barr virus (EBV), HHV-6 and Cytomegalovirus (CMV) were assessed in the GI tract of human immunodeficiency virus (HIV) positive patients and of uninfected patients. The analysis revealed a significantly higher detection rate of EBV and HHV-6 in HIV-infected individuals than in uninfected subjects (88.5 vs 63%; p = 0.03). Moreover, EBV DNA load was significantly higher in the stomach of HIV patients than in controls. These data suggest that the HIV infection status may increase the persistence of these viruses in the GI compartment. Intriguingly, CMV DNA was undetectable in all biopsy specimens analyzed.

Abstract
Hunter syndrome or mucopolysaccharidosis II (MPS II) is a rare X-linked disease caused by a deficiency of the iduronate-2-sulphatase (12S) lysosomal enzyme, resulting in a progressive accumulation of glycosaminoglycans (GAGs). Enzyme replacement therapy (ERT) with recombinant human 12S idursulfase has been used infrequently in children < 5 years. We present the case of a 7 years and 10 months-old child, who was diagnosed with a severe form of MPS II at the age of 3 years, and who began a 36 months' treatment with idursulfase at 4 years 10 months. After 10 months, GAG urinary excretion was normal, but after just 4 months the liver and spleen had decreased in size, returning to normal limits by 36 months. Significant bone remodeling was noted after 16 months. Cardiac and neurological development, however, progressively deteriorated. The only adverse reactions were episodic inflammations of the upper and/or lower respiratory tract, but there was no otitis. Early use of ERT, presuming good treatment adherence, can significantly improve bone abnormalities.

Abstract
Because of the considerable impact of human cytomegalovirus (HCMV) infection, sensitive, specific, and standardized methods are required for rapid and accurate evaluation of viral load in monitoring transplant recipients. The aim of the present study was to evaluate the usefulness of a multiplex polymerase chain reaction (PCR) for the coamplification of HCMV-DNA and beta-globin genomic sequence in polymorphonuclear leukocytes (PMNL). Analysis and quantification of PCR products were carried out by a DNA enzyme immunoassay (DEIA), which is based on the hybridization of amplified DNA with a single-stranded DNA probe, which coats microtitre wells. Colorimetric detection of the DNA-antibody complex was carried out and optical density (O.D.) was recorded at 450/630 nm. To quantify HCMV/DNA load, a standard curve to which samples O.D. refer was obtained by amplifying serial dilutions of recombinant PGEM-3Z plasmid DNA containing a genomic fragment of glycoprotein B. 340 PMNL specimens from 102 solid organ recipients were tested for the detection of pp65 antigen and HCMV-DNA. The results showed a good correlation between viral load and clinical symptoms of HCMV infection; high specificity and predictive values for HCMV disease were found by PCR, using a cut-off limit of 10(3) genomic copies per 2 x 10(5) PMNL. These findings indicate that the system described is an efficient and reproducible diagnostic method easy to apply for routine diagnosis and therapeutic monitoring of transplanted patients.

Abstract
The use of sensitive and specific methods for rapid and reliable diagnosis is required due to the considerable impact of human cytomegalovirus (HCMV) in organ transplant recipients. For this purpose the demonstration of the presence of viral antigens in peripheral blood leukocytes (PMNLs) and of viral nucleic acids in the same cells or in sera would seem to be of valid support. The present study was designed to test pp65 antigen, HCMV DNA and HCMV late mRNA in order to provide clinical information for the management of the infection. Fifty solid organ recipients were monitored for six months after transplant. The data obtained from the various tests were analysed from the first evidence of HCMV infection revealed by positive antigenaemia and/or DNA-polymerase chain reaction (PCR). In 3 asymptomatic and in 7 symptomatic patients, PCR became positive 1-2 weeks before antigenaemia but PCR did not discriminate the clinical evolution of HCMV infection. The antigenaemia test well correlated to the development of viral infection being positive in all symptomatics and in 31, 2% of asymptomatics. The antigenic load > 100/2 x 10(5) positive cells was always associated with clinical signs of illness. The detection of late mRNA was more indicative of the virus replicative status in the follow-up of patients treated with ganciclovir. In some cases there was evidence, prior to the other two tests, the block of viral replication due to the antiviral therapy and in others the onset of HCMV infection relapse.

Abstract
The capacity of human and murine polyclonal and monoclonal antibodies to inhibit lipopolysaccharide (LPS)-induced tumor necrosis factor-alpha (TNF-alpha) release from human monocytes was investigated. Human pooled immunoglobulin G (IVIG), human IgM monoclonal antibody (HA-1A) directed against the lipid A moiety of LPS, and murine IgG monoclonal antibody (MT-1F) raised in mice against antibiotic-treated Escherichia coli O6:K- were either added simultaneously with LPS to monocytes or preincubated for 1 h at 37 degrees C before being added to monocytes. TNF-alpha content in the monocyte supernatants was then tested. Simultaneous addition of increasing concentrations of IVIG (from 0.3 to 2.5 mg/ml) and 10 micrograms/ml of LPS to monocytes induced an enhanced release of TNF-alpha by monocytes in a dose dependent fashion. Preincubation of IVIG with LPS abolished the additive effect, but did not inhibit LPS-induced TNF-alpha release by monocytes. The simultaneous addition of LPS and HA-1A to monocytes had no additive effect nor did it inhibit TNF-alpha release. On the other hand, inhibition of TNF-alpha release was observed when HA-1A was preincubated with LPS before being added to monocytes. In all instances MT-1F inhibited TNF-alpha release when the monocytes were stimulated with smooth type LPS, but not with LPS isolated from rough mutants.

Abstract
In a randomized double blind study, we analyzed the efficacy of IVIG in the infectious complications in patients at high risk of developing sepsis syndrome. Two groups of twenty patients were enrolled, one receiving 250 mg/Kg of IVIG on the first and seventh day after admission and the other receiving sterile saline as placebo. Serum samples were drawn before IVIG administration and 24, 48 and 72 hours afterwards. The same schedule was used for patients treated with placebo. Sera pooled from healthy donors served as controls. On all the samples, opsonic and bactericidal activity as well as C3, total IgG and serum TNF content were tested. IVIG did not significantly affect total IgG and C3 content. Similarly, opsonic and bactericidal activity tested against E. coli 06 :K-, E. coli 0111 and SAC I was not modified ranging within HPS values. Furthermore, IVIG administration did not change the TNF level. A lower incidence of bacteremia in IVIG treated patients was observed.

Abstract
The murine immune response to Escherichia coli O6:K-alone or pre-exposed to 0.1 x MIC of aztreonam was investigated. Relative to mice immunized with untreated bacteria, mice immunized with antibiotic-treated microorganisms presented a significantly enhanced protection towards a challenge of 100 x LD50 of viable E. coli O6:K-. Previous injection of 0.1 mL of serum drawn from mice immunized with treated and untreated bacteria protected non-immunized mice towards a challenge of 10 x LD50 of viable E. coli O6:K--. Serum from mice immunized with treated bacteria also protected non-immunized mice towards a lethal challenge of E. coli O111. The antiserum contained high titre of IgG antibodies that cross-reacted with lipopolysaccharide isolated from smooth and rough Gram-negative bacteria. Immunoblotting showed additional bands of reactivity to the untreated E. coli O6:K-. Immunization with antibiotic-treated bacteria led to the production of type specific and cross reactive antibodies that protected animals against viable homologous and heterologous lethal challenges.

Abstract
Aneurysms of the abdominal aorta are often diagnosed in the over-75s. Although for many Authors the presence of risk factors such as cardiopathies, cerebrovascular problems, renal or respiratory insufficiency, which are clearly more frequent in elderly patients, represent a contraindication to the intervention of choice, personal experience has shown that surgery remains the best solution. In fact, in a group of patients operated on for aneurysm of the abdominal aorta in a heart, no significant differences in age-related mortality were observed. Surgery therefore remains the treatment of choice in the elderly too for it must also be remembered that the natural history of the disease has shown that, in a comparatively short time, the aneurysm ruptures and operating mortality is markedly higher.

Abstract
The hypothesis of a different immunogenicity between untreated and antibiotic-treated Escherichia coli was investigated in vivo. Groups of mice were injected weekly for eight weeks with formalin-killed E. coli ATCC 25922 either exposed or not to 0.1 x MIC of aztreonam. A group of mice injected with sterile saline only served as control. IgG production towards whole bacteria was clearly enhanced in the group immunized with antibiotic-treated E. coli as shown in ELISA assays. In the same group, the appearance of additional bands of reactivity in the region of major outer membrane proteins was observed in immunoblot experiments as well as an enhanced protection towards a challenge of 10 x LD50 of live E. coli. These findings seem to support the hypothesis that sub-MICs of antibiotics modify the bacterial surface influencing host-parasite relationships.

Abstract
Infection by hepatitis B (HBV) and/or delta virus (HDV), is the most frequent acquired pathology in patients affected by end-stage hepatic disease, candidates for liver transplant. To reduce the risk of virus reactivation after surgery, we used alpha Interferon (IFN) therapy in patients who were HBV-DNA and/or HDV-RNA positives before transplant. Our protocol included alpha IFN at low dosage associated to a thymic hormone that seems to have a synergistic activity with IFN. We have evaluated in four patients, affected by post hepatitic end-stage liver disease, the outcome of HBV and HDV markers in relation to immunological response during treatment. Our interest has been focused on monocyte and natural killer cytotoxic activity. The data show that all patients, before starting therapy, had evidence of active phase viral replication. They also displayed low values of the immunological parameters tested. The study of viral markers showed decrease of HBV and HDV in all patients. The relation between viral markers and natural killer and monocyte cytotoxicity was very interesting; during the treatment we observed a marked increase of both activities. At the same time no relevant modifications in the other immunological parameters tested were found.

Abstract
In the this study the modification of lymphocyte subsets (T3, T4, T8) and Natural Killer (NK) cells in organ transplanted patients treated with Cyclosporin A (CyA) in the course of viral infection, have been analyzed. Different subsets have been studied with the monoclonal antibody method and infective processes have been verified by serological data of seroconversion. Our study has shown that CyA at the adopted doses does not alter NK response to viral infection; in fact, in patients with seroconversion, higher NK values and lower OKT4/OKT8 ratio values have been found with respect to patients who did not show any viral infection serologic data. Furthermore an increased incidence of reject crisis has been observed in patients with seroconversion.

Abstract
The AA. suggest a dose-method of Hb A2, which implies the adoption of tris-EDTA-Glycin tampon with a different concentration anode-cathode; the electrophoretic bands, obtained by cellulose acetate electrophoresis, are eluted in the same tampon, but it is suggested to use 15 cc of tampon for A fraction elution and 1.5 cc for A2 fraction elution. The lecture must be done by spectrophotometry to 415 nm. By using this method the normal values of Hb A2 ranges from 1.7% to 3.5% and so there isn't any confusion with pathologic values. The AA. compare this method with that recommend a densitometric lecture of the strips and with those that imply the adoption of cromathographic columns, and they underline its advantages. In conclusion, the AA. suggest the adoption of an unified method for microcytemic screening that could be used in all laboratories.
