Abstract
BACKGROUND The risk for symptomatic COVID-19 requiring hospitalization is higher in the older population. The course of the disease in hospitalised older patients may show significant variation, from mild to severe illness, ultimately leading to death in the most critical cases. The analysis of circulating biomolecules involved in mechanisms of inflammation, cell damage and innate immunity could lead to identify new biomarkers of COVID-19 severity, aimed to improve the clinical management of subjects at higher risk of severe outcomes. In a cohort of COVID-19 geriatric patients (n= 156) who required hospitalization we analysed, on-admission, a series of circulating biomarkers related to neutrophil activation (neutrophil elastase, LL-37), macrophage activation (sCD163) and cell damage (nuclear cfDNA, mithocondrial cfDNA and nuclear cfDNA integrity). The above reported biomarkers were tested for their association with in-hospital mortality and with clinical, inflammatory and routine hematological parameters. Aim of the study was to unravel prognostic parameters for risk stratification of COVID-19 patients. RESULTS Lower n-cfDNA integrity, higher neutrophil elastase and higher sCD163 levels were significantly associated with an increased risk of in-hospital decease. Median (IQR) values observed in discharged vs. deceased patients were: 0.50 (0.30-0.72) vs. 0.33 (0.22-0.62) for n-cfDNA integrity; 94.0 (47.7-154.0) ng/ml vs. 115.7 (84.2-212.7) ng/ml for neutrophil elastase; 614.0 (370.0-821.0) ng/ml vs. 787.0 (560.0-1304.0) ng/ml for sCD163. The analysis of survival curves in patients stratified for tertiles of each biomarker showed that patients with n-cfDNA integrity < 0.32 or sCD163 in the range 492-811 ng/ml had higher risk of in-hospital decease than, respectively, patients with higher n-cfDNA integrity or lower sCD163. These associations were further confirmed in multivariate models adjusted for age, sex and outcome-related clinical variables. In these models also high levels of neutrophil elastase (>150 ng/ml) appeared to be independent predictor of in-hospital death. An additional analysis of neutrophil elastase in patients stratified for n-cfDNA integrity levels was conducted to better describe the association of the studied parameters with the outcome. CONCLUSIONS On the whole, biomarkers of cell-free DNA integrity, neutrophil and macrophage activation might provide a valuable contribution to identify geriatric patients with high risk of COVID-19 in-hospital mortality.

Abstract
The background of this study is to assess the feasibility, clinical utility and safety of intra-corporeal robotic-sewn anastomosis (ICrA) in completely robotic right hemicolectomy (CRH) for adenocarcinoma. A protocol for completely robotic right hemicolectomy (CRH) and intra-corporeal robotic-sewn anastomosis (ICrA), was established at the authors' institution from January 2012 through December 2017. Univariate and multivariable models were constructed to explore the prognostic significance of clinical and surgical findings. Survival and recurrence analysis were performed using standard univariable and multivariable methods. The study population consisted of 123 patients. The median number of examined lymph nodes (ELN) was 25 (range 1-59), the median number of positive lymph nodes (PLN) was 1 (range 0-21). Mean operative time was 240 min (SD 43.56, range 180-360 min), and conversion to open rate was 0%. Anastomotic leaks rate was 1.6%. The median overall survival was 69 months. This pilot series, in which an intra-corporeal robotic-sewn anastomosis (ICrA) was performed during CRH, demonstrated the safety and feasibility of this approach. Compared to the current standard of care at a high-volume center, ICrA was associated with post-operative surgical outcomes similar to those reported in the literature. These results call for further validation in a prospective and controlled setting to be fully incorporated into clinical practice.

Abstract
BACKGROUND Neoplastic T-cell recruitment into the skin is a critical step in the pathogenesis of mycosis fungoides (MF), and the cutaneous T-cell attracting chemokine, CTACK/CCL27, might be involved. OBJECTIVES To investigate the clinical and prognostic significance of CTACK/CCL27 levels in patients with early-stage MF. METHODS Serum samples and skin biopsy specimens were collected from 15 patients at the time of diagnosis and after the end of treatment with psoralen plus ultraviolet A/interferon alfa-2b combination therapy. Serum samples were also collected from 20 healthy donors as controls. CTACK/CCL27 serum levels were analysed by enzyme-linked immunosorbent assays. CTACK/CCL27 tissue expression was determined by immunohistochemistry on skin biopsy specimens taken at diagnosis and after therapy. Event-free survival was taken as the primary clinical outcome. RESULTS In patients with MF at diagnosis, CTACK/CCL27 serum levels were not significantly different from healthy controls, whereas CTACK/CCL27 expression in the skin was increased in 87% of cases compared with normal controls. After therapy, all patients obtained a clinical complete remission, serum levels did not change significantly and tissue expression remained abnormal in 80% of patients, even if complete histological remission was recorded. Serum levels were not significantly different in cases with different intensity of cutaneous immunostaining. Eight patients experienced a relapse: the combination of high CTACK/CCL27 levels both in sera and skin increased the probability of experiencing an event at 51 months from 36% to 83%. CONCLUSIONS Our data seem to indicate that CTACK/CCL27 levels in skin and sera after therapy might be correlated with risk of recurrence.

Abstract
Metabolic syndrome is associated to chronic low grade inflammation, characterized by increased levels of inflammatory cytokines, such as Tumor Necrosis Factor-alpha (TNF-alpha) and Interleukin-6 (IL-6). In particular, TNF-alpha causes a decrease in the insulin-stimulated kinases related to the early phases of the insulin cascade, thereby leading to insulin resistance. Etanercept is a human fusion protein used in the treatment of psoriasis and inflammatory arthritis. It blocks inflammatory response by interfering in the binding of TNF-alpha to its receptors. The aim of this case report study is to verify the effect of Etanercept on insulin sensitivity, lipid profile and inflammatory status in psoriatic patients. Nine psoriatic patients with stable, active, plaque type psoriasis were enrolled and treated with Etanercept for 24 weeks. We found an improvement in the metabolic assessment with a significant reduction of insulin plasma levels. In particular, this treatment allows to maintain their euglycemic state with lower insulin plasma levels, as confirmed by the improved Homeostasis Model Assessment (HOMA) index. We conclude that Etanercept, probably acting on inflammation, improves insulin sensitivity in psoriatic subjects.

Abstract
Many epidemiological data indicate the presence of a strong familial component of longevity that is largely determined by genetics, and a number of possible associations between longevity and allelic variants of genes have been described. A breakthrough strategy to get insight into the genetics of longevity is the study of centenarians, the best example of successful ageing. We review the main results regarding nuclear genes as well as the mitochondrial genome, focusing on the investigations performed on Italian centenarians, compared to those from other countries. These studies produced interesting results on many putative "longevity genes". Nevertheless, many discrepancies are reported, likely due to the population-specific interactions between gene pools and environment. New approaches, including large-scale studies using high-throughput techniques, are urgently needed to overcome the limits of traditional association studies performed on a limited number of polymorphisms in order to make substantial progress to disentangle the genetics of a trait as complex as human longevity.

Abstract
Interleukin-6 (IL-6), a powerful inflammatory mediator, plays a pivotal role in the pathogenesis of insulin resistance and type 2 diabetes. Recently, the IL-6 promoter polymorphism, at position -174 (G > C), has been associated to insulin sensitivity although contrasting data have been reported. The aim of this study was to evaluate the effect of the IL-6-174 G > C polymorphism on insulin resistance. In 238 type 2 diabetic patients without diabetic complications and in 255 control subjects, age and gender-matched, we evaluated the IL-6 -174 G > C genotype, the IL-6 plasma levels and the insulin resistance by the homeostasis model assessment (HOMA). The levels of IL-6 and HOMA were not genotype-dependent and were higher in diabetic patients (p < 0.01). Control subjects, both C+ (CG + CC genotypes) and C- (GG genotype) carriers, showed IL-6 plasma levels significantly related to BMI, fasting insulin and HOMA. The same relationships were found in C+ diabetic carriers. Differently, diabetic C- carriers did not show any relationship between IL-6 levels and all the evaluated variables. Interestingly, all the correlations were dependent on BMI. These findings highlight that IL-6-174 G > C polymorphism affects insulin resistance in type 2 diabetes, where C+ carriers have an insulin resistance "IL-6-sensitive", while C- carriers do not. The identification of two categories of diabetic patients may, therefore, lead to different therapeutic strategies in the management of insulin resistance.

Abstract
The combined effect of Peroxisome proliferator-activated receptor gamma (PPARG) Pro/Ala and interleukin-6 G174C gene variants, was evaluated in 429 Caucasian subjects in order to determine whether subjects carrying both variants were at different risk for obesity. In particular, the combined contribution of these two variants (both independent and interaction effects) to the total variation of obesity-related factors was estimated. All subjects were genotyped for codon 12 Pro/Ala locus variability and for the interleukin-6-174 C/G promoter polymorphism. Subjects with the Ala variant had significantly lower BMI, insulin resistance, triglyceride levels than those without. Furthermore, subjects with Ala variant had significantly lower IL-6 levels (0.88 +/- 0.9 vs 1.61 +/- 2.25 pg/ml; p = 0.041). In contrast, the IL6-C variant was significantly associated with lower plasma IL-6 and with lower total cholesterol levels but was not significantly associated with any other obesity risk factors. Indeed, subjects carrying both PPARG and IL-6 gene variants, had a clearly more favourable profile of obesity related risk factors than subjects with one variant, having Ala+/C+ carriers lower BMI (22.8 +/- 2.3 vs 24.14 +/- 1.9; f = 5.31; p < 0.005), insulin resistance (1.49 +/- 0.70 vs 2.13 +/- 0.92; f = 4.342; p = 0.038) and triglyceride levels (79.15 +/- 32.9 vs 98 +/- 6.73 mg/dl; f = 3.120; p < 0.005). These findings suggest that the effect of the two genetic variants on 'obesity related' factors is additive.

Abstract
In the present study a novel inter-Alu PCR technique that allows one to detect inter-individual differences in the genomic regions flanked by Alu repetitive sequences was developed. Two primers complementary to sequences present in different Alu repeats and marked with two different fluorochromes were used in the same PCR reaction, and the PCR products were separated and analyzed by capillary electrophoresis using an automatic sequencer. The method is highly reliable, and three patterns of peaks (QM376-400, QM780-790 and QM480) appeared to be representative for germ-line polymorphisms, as suggested by the results obtained in nine couples of monozygotic twins and four three-generation families. The frequency of these polymorphic peaks was studied in two different age groups (100 young subjects and 69 centenarians). In two out of the three regions (QM376-400 and QM480) a significant increase in homozygote genotypes frequency was observed in centenarians. These counterintuitive results suggest that increased homozygosity contributes to human longevity. This novel inter-Alu PCR approach could represent a valuable tool to identify longevity-associated DNA sequences interspersed throughout human genome, without making any a priori assumption about their nature and function.

Abstract
Gender accounts for important differences in the incidence and prevalence of a variety of age-related diseases. Considering people of far advanced age, demographic data document a clear-cut prevalence of females compared to males, suggesting that sex-specific mortality rates follow different trajectories during aging. In the present investigation, we report data from a nationwide study on Italian centenarians (a total of 1162 subjects), and from two studies on centenarians living in two distinct zones of Italy, i.e., the island of Sardinia (a total of 222 subjects) and the Mantova province (Northern Italy) (a total of 43 subjects). The female/male ratio was about 2:1 in Sardinia, 4:1 in the whole of Italy, and about 7:1 in the Mantova province. Thus, a complex interaction of environmental, historical and genetic factors, differently characterizing the various parts of Italy, likely plays an important role in determining the gender-specific probability of achieving longevity. Gender differences in the health status of centenarians are also reported, and an innovative score method to classify long-lived people in different health categories, according to clinical and functional parameters, is proposed. Our data indicate that not only is this selected group of people, as a whole, highly heterogeneous, but also that a marked gender difference exists, since male centenarians are less heterogeneous and more healthy than female centenarians. Immunological factors regarding the age-related increase in pro-inflammatory status, and the frequency of HLA ancestral haplotypes also show gender differences that likely contribute to the different strategies that men and women seem to follow to achieve longevity. Concerning the different impact of genetic factors on the probability of reaching the extreme limits of the human life-span, emerging evidence (regarding mtDNA haplogroups, Thyrosine Hydroxilase, and IL-6 genes) suggests that female longevity is less dependent on genetics than male longevity, and that female centenarians likely exploited a healthier life-style and more favorable environmental conditions, owing to gender-specific cultural and anthropological characteristics of the Italian society in the last 100 years.

Abstract
A karyological study of four species of gobiid fishes, Gobius niger, G. paganellus, G. cobitis, and Zosterisessor ophiocephalus (Perciformes, Gobiidae), was conducted by standard, fluorochrome staining (using chromomycin A3, mithramycin, and DAPI), Alu-I digestion, and CBG- and RBG-banding methods. Our cytogenetic data indicate that heterochromatin in these taxa is highly differentiated, exhibiting heterogeneity in staining characteristics, and presumably in underlying DNA sequences, and a different capability for promoting Robertsonian fusions.

Abstract
Basal natural killer (NK) cell activity in peripheral blood lymphocytes (PBLs) of 29 patients with gynecologic malignancy and 10 healthy controls was performed using K 562 cell line. A significant decrease of NK cell activity was observed in patients with gynecologic malignancy (p = 0.003). The NK cell activity of patients with poorly differentiated tumor or with stage IV of disease was significantly reduced with respect to patients at any other lower grade or earlier stage. We conclude that in patients with gynecologic malignancies there is a decrease of basal NK cell activity of PBLs, which is more significant in cases of distant tumor dissemination or poorly differentiated tumor (p less than 0.001).

Abstract
In 156 patients with gynecologic neoplasia the sieric levels of tumor markers (CA 125, CA 15-3, CA 72.4, SCC and 90 K) before the primary treatment and during the follow-up have been evaluated. In the patients with ovarian cancer elevated levels of CA 125 (80%), CA 72.4 (62%), 90 K (49%) and CA 15-3 (16.6) were found. The integrated evaluation of CA 125 and 90 K sieric levels was positive in the 86% of cases. The evaluation of CA 125 in combination with 90 K seems to facilitate the earlier detection of ovarian cancer recurrences. Elevated levels of SCC (89%) were found in the patients with cervical cancer. In the patients with endometrial or vulvar cancer the evaluation of these tumor markers was not significant.

Abstract
Several Authors demonstrate changes in maternal immune system in women with pregnancy induced hypertension (PIH). In this study peripheral mononuclear cells were isolated in fifteen primigravid women with PIH and tested with monoclonal antibodies Leu 4, Leu 3, Leu 2 and Leu 7; in four women were studied monoclonal antibodies anti-Tac. The results were compared with a normotensive pregnant control group. T helper and T suppressor were increased but showed no statistical difference. The difference was statistically significant only for th NK cells. Tac antigen was expressed only on the Leu 3 induce subset. The PIH occurs because of a failure of maternal immune system.
