Abstract
Primary leiomyoma of the liver (PLL) is a rare benign tumor occurring in immunosuppressed people. From 1926 less than fifty cases are reported in the scientific literature and about half are in immunocompetent patients. Etiology of this kind of lesion is not yet well known. We report a case of primary hepatic leiomyoma in a 60-year-old immunocompetent woman. The patient presented with lipothymia with unexpected vomiting. She underwent an ultrasound (US), and a computed tomography (CT) scan that revealed the presence of a single, solid lesion about 9 cm located between the S5 and S8 segment of the liver. It showed a well-defined, heterogeneous hypodensity with internal and peripheral enhancement and various central hypoattenuating areas and no wash-out in the portal and the late phases. Because of her symptoms and the risk of malignancy, the patient underwent a surgical liver resection. Histological diagnosis was primary leiomyoma of the liver. The patient had an uneventful recovery and was discharged after 7 days. At 30 months follow-up there were no symptoms and no evidence of disease. Leiomyoma of the liver is a rare benign neoplasm of which clinical symptoms are nonspecific and the exact radiological diagnosis still remains a challenge for radiologists. Etiology is still unclear and usually PLL represents an incidental diagnosis. Surgery plays a primary role not only in the treatment algorithm, but also in the diagnostic workout.

Abstract
In our study, we investigated the role of CD39 on tumor-infiltrating CD8+ T lymphocytes (CD8+ TILs) in colorectal, head and neck and pancreatic cancers. Partially confirming recent observations correlating the CD39 expression with T-cell exhaustion, we demonstrated a divergent functional activity in CD39+ CD8+ TILs. On the one hand, CD39+ CD8+ TILs (as compared to their CD39- counterparts) produced significantly lower IFN-γ and IL-2 amounts, expressed higher PD-1, and inversely correlated with perforin and granzyme B expression. On the other, they displayed a significantly higher proliferative capacity ex vivo that was inversely correlated with the PD-1 expression. Therefore, CD39+ CD8+ TILs, including those co-expressing the CD103 (a marker of T resident memory [TRM] cells), were defined as partially dysfunctional T cells that correlate with tumor patients with initial progression stages. Interestingly, our results identified for the first time a single nucleotide polymorphism (SNP rs10748643 A>G), as a genetic factor associated with CD39 expression in CD8+ TILs. Finally, we demonstrated that compounds inhibiting CD39-related ATPases improved CD39+ CD8+ T-cell effector function ex vivo, and that CD39+ CD8+ TILs displayed effective suppression function in vitro. Overall these data suggest that the SNP analysis may represent a suitable predictor of CD39+ CD8+ T-cell expression in cancer patients, and propose the modulation of CD39 as a new strategy to restore partially exhausted CD8+ TILs.

Abstract
Background: Laparoscopic surgery is a choice of treatment for liver diseases; it can decrease postoperative morbidity and length of hospital stay (LOS). Hepatocellular carcinoma (HCC) in patients with cirrhosis and portal hypertension may benefit from minimally invasive liver resections (MILRs) instead of open liver resections (OLRs). Whether minimally invasive approaches are superior to conventional ones is still a matter of debate. We thus aimed to gather the available literature on this specific topic to achieve greater clarity. Materials and Methods: PubMed, EMBASE and Web of Sciences databases were assessed for studies comparing OLRs versus MILRs for HCC in cirrhotic patients up to February 2020. Data from our surgical experience from June 2010 to February 2020 were also included. Demographic characteristics, liver function, the presence of portal hypertension, tumor number, and tumor size and location were assessed; operative time, need for Pringle maneuver, estimated blood loss (EBL), major or minor hepatectomy performance, and conversion rate were evaluated for operative findings. Postoperative outcomes and liver-related complications, surgical site infection (SSI) rate, blood transfusion (BT) rate, need for reintervention, LOS, in-hospital or 30-day mortality, and radicality of resection were also considered. Meta-analysis was performed employing Review Manager 5.3 software. Results: One thousand three hundred twenty-one patients from 13 studies and our own series were considered in the meta-analysis. At preoperative settings, the OLR and MILR groups differed significantly only by tumor size (4.4 versus 3.0, P = .006). Laparoscopic procedures resulted significantly faster (120.32-330 minutes versus 146.8-342.75 minutes, P = .002) and with lower EBL than open ones (88-483 mL versus 200-580 mL, P < .00001), thus requiring less BTs (7.9% versus 13.2%, P = .02). In terms of overall morbidity, minimally invasive surgeries resulted significantly favorable (19.32% versus 38.04%, P < .00001), as well as for ascites (2.7% versus 12.9% P < .00001), postoperative liver failure (7.51% versus 13.61% P = .009), and SSI (1.8% versus 5.42%, P = .002). Accordingly, patients who had undergone MILRs had significantly shorter postoperative hospitalization than patients who underwent conventional open surgery (2.4-36 days versus 4.2-19 days P < .00001). Both groups did not differ in terms of mortality rate and radicality of resection (OLR 93.8% versus 96.1% laparoscopic liver resection, P = .12). Conclusions: Based on the available evidence in the literature, laparoscopic resections rather than open liver ones for HCC surgery in cirrhotic patients seem to reduce postoperative overall morbidity, liver-specific complications, and LOS. The lack of randomized studies on this topic precludes the possibility of achieving defining statements.

Abstract
BACKGROUND To analyze long-term results and risk of relapse in the clinical TNM stages II and III, mid-low rectal cancer patients (RC pts), treated with transanal local excision (LE) after major response to neoadjuvant chemoradiation (n-CRT). METHODS Thirty-two out of 345 extraperitoneal cT3-4 or N+ RC pts (9.3%) underwent LE. INCLUSION CRITERIA extraperitoneal RC, adenocarcinoma, ECOG Performance Status ≤2. Pts with distant metastases were excluded. RESULTS All pts showed histologically clear margins of resection and 81.2% were restaged ypT0/mic/1. Nine out of 32 (28.1%) pts relapsed: 7 (21.8%) showed a local recurrence, of which 5 (15.6%) at the endorectal suture, 1 (3.1%) pelvic and 1 (3.1%) mesorectal. Two pts (6.2%) relapsed distantly. Among the pT0/1, 11.5% relapsed vs 100% of the pT2 and pT4 ones. The six pts relapsing locally or in the mesorectal fat underwent a salvage total mesorectal excision surgery. The old patient with pelvic recurrence relapsed after 108 months and underwent a re-irradiation; the two pts with distant metastases were treated with chemotherapy followed by radical surgery. CONCLUSIONS Presently combined approach seems a valid option in major responders, confirming its potential curative impact in the ypT0/mic/1 pts. A strict selection of pts is basic to obtain favourable results.

Abstract
PURPOSE We recently reported that a high BMI and high waist circumference prevalence is present in Sicilian children and that the male gender is associated with a significant risk of obesity. Early-life and parent-related risk factors were investigated 1521 Sicilian children (752 females and 769 males, aged 9.0-14.0 years) to identify biological and environmental factors that can contribute to obesity onset. METHODS Anthropometric measurements of children, their urban vs rural area provenience, birth weight and neonatal feeding were collected. In addition, the BMI and educational level of their parents and the perception of their child weight status were investigated. RESULTS In the study cohort, the prevalence of overweight and obesity was 27.2 and 14.1 %, respectively, significantly (p < 0.05) higher in males than in females. Breastfeeding emerged as a protective factor (OR 0.64; p < 0.0005), while risk factors for developing childhood obesity were a birth weight ≥4.0 kg (OR 1.83; p < 0.05), an overweight or obese mother (OR 2.33; p < 0.0001) or father (OR 1.68; p < 0.0001) and a mother with a low/medium education level (OR 1.72; p < 0.005). CONCLUSION Understanding risk factors for pediatric obesity is a prerequisite to identify children at highly risk of being obese and to predispose early intervention strategies.

Abstract
Cytosolic PLA2 (cPLA2) and Ca(2+)-independent PLA2 (iPLA2) play a significant role in insulin β-cells secretion. Bacterial infections may be responsible of the onset of diabetes. The mechanism by which Staphylococcus aureus infection of INS-1 cells alters glucose-induced insulin secretion has been examined. After acute infection, insulin secretion and PLA2 activities significantly increased. Moreover, increased expressions of phospho-cPLA2, phospho-PKCα and phospho-ERK 1/2 were observed. Chronic infection causes a decrease in insulin release and a significant increase of iPLA2 and COX-2 protein expression. Moreover, insulin secretion in infected cells could be restored using specific siRNAs against iPLA2 isoform and specific COX-2 inhibitor.

Abstract
The expression of adiponectin receptors has been demonstrated in human and rat pancreatic beta cells, where globular (g) adiponectin rescues rat beta cells from cytokine and fatty acid-induced apoptosis. The aim of our study was to evaluate whether adiponectin has a direct effect on insulin secretion and the metabolic pathways involved. Purified human pancreatic islets and rat beta cells (INS-1E) were exposed (1 h) to g-adiponectin, and glucose-induced insulin secretion was measured. A significant increase in glucose-induced insulin secretion was observed in the presence of g-adiponectin (1 nmol/l) with respect to control cells in both human pancreatic islets (n = 5, p < 0.05) and INS-1E cells (n = 5, p < 0.001). The effect of globular adiponectin on insulin secretion was independent of AMP-dependent protein kinase (AMPK) activation or glucose oxidation. In contrast, g-adiponectin significantly increased oleate oxidation (n = 5, p < 0.05), and the effect of g-adiponectin (p < 0.001) on insulin secretion by INS-1E was significantly reduced in the presence of etomoxir (1 μmol/l), an inhibitor of fatty acid beta oxidation. g-Adiponectin potentiates glucose-induced insulin secretion in both human pancreatic islets and rat beta cells via an AMPK independent pathway. Increased fatty acid oxidation rather than augmented glucose oxidation is the mechanism responsible. Overall, our data indicate that, in addition to its anti-apoptotic action, g-adiponectin has another direct effect on beta cells by potentiating insulin secretion. Adiponectin, therefore, in addition to its well-known effect on insulin sensitivity, has important effects at the pancreatic level.

Abstract
The sensitivity of the mitochondrial energy production system to propofol (DPP) has been investigated in rat brain synaptosomes. DPP at 0.8 mM concentration produced a partial inhibition of coupled respiration, an apparent decrease of the oxygen uptake stimulation induced by CCCP and a full inhibition of the mitochondrial ATP production by synaptosomes. Higher concentrations of DPP (1 mM) fully abolish uncoupler-dependent stimulation and at 1.3 mM DPP also coupled respiration is completely blocked. Similar results were obtained when dinitrophenol replaced CCCP and phenol or propylbenzene replaced DPP. The presence of the alkyl residues seems critical for the DPP effect. In the presence of 30 mM glutamate both respiration and ATP production are enhanced but DPP effects are similar to those obtained in the absence of glutamate.
