The mythical Helen at the mirrow crying her lost beauty and youth, the old courtesan Laide vowing her mirrow to Aphrodite as she needs it no more, introduce to the problem of gradus aetatum (the ages of life) for women in Greek and Latin literature, both pagan and Christian. The second part of the research deals with the common places of puer senex, puer maior sua aetate as used by ancient writers for a girl. Physical and spiritual age were considered in opposition in a philosophical and religious perspective. The transformation of a young girl into an old woman is strictly linked to the transformation of a woman into a man, according to the typology of mulier virilis. So on a spiritual level young women may become models for old men; however women have no age as their social role prevails. The last part focuses on the problem of old women in antiquity. Youth and beauty, positive values in pagan texts, were considered as belonging to the earthly life in Christian works and had to be overcome. Holy beauty is the only recognized form of beauty for ascetic women and they acquired it after death. In late antiquity ideal women had no sex and no age, no mirrow and no physical portrait
INfluenza Vaccine Indication During therapy with Immune checkpoint inhibitors: a transversal challenge. The INVIDIa study
Aim: Considering the unmet need for the counseling of cancer patients treated with immune checkpoint inhibitors (CKI) about influenza vaccination, an explorative study was planned to assess flu vaccine efficacy in this population. Methods: INVIDIa was a retrospective, multicenter study, enrolling consecutive advanced cancer outpatients receiving CKI during the influenza season 2016-2017. Results: Of 300 patients, 79 received flu vaccine. The incidence of influenza syndrome was 24.1% among vaccinated, versus 11.8% of controls; odds ratio: 2.4; 95% CI: 1.23-4.59; p = 0.009. The clinical ineffectiveness of vaccine was more pronounced among elderly: 37.8% among vaccinated patients, versus 6.1% of unvaccinated, odds ratio: 9.28; 95% CI: 2.77-31.14; p < 0.0001. Conclusion: Although influenza vaccine may be clinically ineffective in advanced cancer patients receiving CKI, it seems not to negatively impact the efficacy of anticancer therapy
Neutralizing antibodies to Omicron after the fourth SARS-CoV-2 mRNA vaccine dose in immunocompromised patients highlight the need of additional boosters
IntroductionImmunocompromised patients have been shown to have an impaired immune response to COVID-19 vaccines.MethodsHere we compared the B-cell, T-cell and neutralizing antibody response to WT and Omicron BA.2 SARS-CoV-2 virus after the fourth dose of mRNA COVID-19 vaccines in patients with hematological malignancies (HM, n=71), solid tumors (ST, n=39) and immune-rheumatological (IR, n=25) diseases. The humoral and T-cell responses to SARS-CoV-2 vaccination were analyzed by quantifying the anti-RBD antibodies, their neutralization activity and the IFN-γ released after spike specific stimulation.ResultsWe show that the T-cell response is similarly boosted by the fourth dose across the different subgroups, while the antibody response is improved only in patients not receiving B-cell targeted therapies, independent on the pathology. However, 9% of patients with anti-RBD antibodies did not have neutralizing antibodies to either virus variants, while an additional 5.7% did not have neutralizing antibodies to Omicron BA.2, making these patients particularly vulnerable to SARS-CoV-2 infection. The increment of neutralizing antibodies was very similar towards Omicron BA.2 and WT virus after the third or fourth dose of vaccine, suggesting that there is no preferential skewing towards either virus variant with the booster dose. The only limited step is the amount of antibodies that are elicited after vaccination, thus increasing the probability of developing neutralizing antibodies to both variants of virus.DiscussionThese data support the recommendation of additional booster doses in frail patients to enhance the development of a B-cell response directed against Omicron and/or to enhance the T-cell response in patients treated with anti-CD20

Estrogen treatment in infertile women with premature ovarian insufficiency in transitional phase: a retrospective analysis
Purpose: During the transitional phase of premature ovarian insufficiency (POI), sporadic resumption of ovulation is possible because of fluctuation of hormonal levels but the chance of spontaneous pregnancy is low, and the main perspective of childbearing in these women is egg donation or adoption. The purpose of the study was to verify whether treatment with estrogens in POI patients in transitional phase could reduce FSH levels and to evaluate if this pre-treatment could improve reproductive outcomes of in vitro fertilization (IVF). Methods: Study patients (26) were administered with valerate estradiol 2 mg daily adding dihydrogesterone 10 mg daily during luteal phase for 3 months before IVF. Control group (26 patients) did not receive any pre-treatment. Ovarian stimulation was conducted in both groups with the same short GnRH-antagonist protocol. Clinical and laboratory data of patients were retrospectively analyzed. Results: In the study group, 4/26 POI patients became spontaneously pregnant during pre-treatment. In the remaining patients, the mean level of FSH after the pre-treatment was significantly reduced compared with baseline. Levels of circulating estradiol on the day of hCG administration were significantly higher in the study group. The total number of MII oocytes retrieved and fertilized oocytes was significantly higher in the study group, as well as the number of embryos transferred for pickup and clinical pregnancy rate. Conclusions: Treatment with estrogens in infertile POI patients in transitional phase reduces circulating FSH levels, hence causing potential spontaneous conception. Moreover, in these patients, estrogen pre-treatment seems to improve IVF outcomes in a GnRH-antagonist short protocol compared to no pre-treatment
Soluble CD73 in the peripheral blood: a potential biomarker in patients with advanced melanoma receiving nivolumab
Background: Anti-PD1 agents are successfully used in therapy to treat patients with advanced melanoma. Here, we retrospectively analysed the CD73 enzyme activity in the peripheral blood of in patients with metastatic melanoma receiving nivolumab. CD73 is an ectonucleotidase able to generate adenosine from AMP. Adenosine in the tumor microenvironment is a potent immune-suppressive mediator, so that inhibition of CD73-generating enzyme or blockade of adenosine receptors is a promising therapeutic strategy to fight cancer.
Materials and methods: CD73 enzyme activity was retrospectively analysed in the plasma of patients before receiving nivolumab. Levels of CD73 enzyme activity was correlated with the survival and progression-free survival of the patients analysed in this study and a multivariate analysis was performed to evaluate the prognostic value of this factor.
Results: 70% of the patients analysed in this study presented detectable CD73 activity in the plasma. High basal levels of sCD73 enzyme activity in serum were significantly associated with poor overall survival and progression-free survival in melanoma patients. In multivariate analysis, levels of CD73 significantly impact on both, overall survival and progression-free survival. Interestingly, we found that low levels of CD73 in the peripheral blood determined before treatment, were significantly associated with disease control rate to nivolumab. Patients who do not respond to nivolumab therapy instead presented higher levels of CD73 enzyme activity in the blood.
Conclusion: Although our results need to be confirmed and validated, they suggest that the activity of CD73 in the peripheral blood of patients with metastatic melanoma might be useful as prognostic factor and potentially as predictor of response to nivolumab treatment. We also postulate that increased levels of CD73 may contribute to affect the response of immunotherapeutic agents in cancer patients
Major Differences in Lymphocyte Subpopulations Between Cerebrospinal Fluid and Peripheral Blood in Non-Hodgkin Lymphoma Without Leptomeningeal Involvement: Flow Cytometry Evidence of a Cerebral Lymphatic System
Cerebrospinal fluid (CSF) flow cytometry has a crucial role in the diagnosis of leptomeningeal disease in onco-hematology. This report describes the flow cytometry characterization of 138 CSF samples from patients affected by non-Hodgkin lymphoma, negative for disease infiltration. The aim was to focus on the CSF non-neoplastic population, to compare the cellular composition of the CSF with paired peripheral blood samples and to document the feasibility of flow cytometry in hypocellular samples. Despite the extremely low cell count (1 cell/mu l, range 1.0-35) the study was successfully conducted in 95% of the samples. T lymphocytes were the most abundant subset in CSF (77%; range 20-100%) with a predominance of CD4-positive over CD8-positive T cells (CD4/CD8 ratio = 2) together with a minority of monocytes (15%; range 0-70%). No B cells were identified in 90% of samples. Of relevance, a normal, non-clonal B-cell population was documented in 5/7 (71%) patients with primary central nervous system lymphoma at diagnosis (p<0.0001), suggesting a possible involvement of blood-brain barrier cell permeability in the pathogenesis of cerebral B-cell lymphomas. The highly significant differences between CSF and paired peripheral blood lymphoid phenotype (p<0.0001) confirms the existence of an active mechanism of lymphoid migration through the meninges
