Abstract
(1) Background: healthcare-associated infections are one of the most frequent adverse events in healthcare delivery worldwide. Several antibiotic resistance mechanisms have been developed, including those to carbapenemase. Cefiderocol (CFD) is a novel siderophore cephalosporin designed to treat carbapenem-resistant bacteria. (2) Methods: we performed a systematic review of all cases reported in the literature to outline the existing evidence. We evaluated real-world evidence studies of CFD in the treatment of carbapenem-resistant (CR) bacteria. (3) Results: a total of 19 publications treating cases of infection by CR bacteria were included. The three most frequent CR pathogens were Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae. A regimen of 2 g every 8 h was most frequently adopted for CFD with a mean treatment duration of 25.6 days. CFD was generally well tolerated, with fewer side effects. The success rate of CFD therapy was satisfactory and almost 70% of patients showed clinical recovery; of these, nearly half showed negative blood cultures and infection-free status. (4) Conclusions: This review indicates that CFD is active against important GN organisms including Enterobacteriaceae, P. aeruginosa, and A. baumannii. CFD seems to have a safe profile.

Abstract
Hyaluronic acid (HA)-based prodrugs bearing double-responsive (acid pH or oxidation) boronates of catechol-containing drugs were used to treat xenografted human prostate tumours (LNCaP) in SCID mice. The HA prodrugs accumulated significantly only in tumours (impressively, up to 40% of the injected dose after 24 h) and in liver, with negligible - actually anti-inflammatory - consequences in the latter. A quercetin-HA prodrug significantly slowed down tumour growth, in a dose-dependent fashion and with a much higher efficacy (up to 4 times) than equivalent doses of free quercetin. In short, boronated HA appears to be a very promising platform for targeted chemotherapy.

Abstract
BACKGROUND Before bariatric surgery (BS), moderate weight loss, left hepatic lobe volume reduction, and micronutrient deficiency (MD) identification and correction are desirable. OBJECTIVES The objective of this study was to assess the safety and the effectiveness of a 4-week preoperative ketogenic micronutrient-enriched diet (KMED) in reducing body weight (BW), left hepatic lobe volume, and correcting MD in patients scheduled for BS. MATERIALS AND METHODS In this prospective pilot study, a cohort of morbidly obese patients (n = 27, 17 females, 10 males) with a mean body mass index (BMI) of 45.2 kg/m2 scheduled for BS underwent a 4-week preoperative KMED. Their BW, BMI, fat mass (FM), fat-free mass (FFM), resting metabolic rate (RMR), left hepatic lobe volume, micronutrient status, and biochemical and metabolic patterns were measured before and after the 4-week KMED. Patient compliance was assessed by validated questionnaires (3-day estimated food records and 72-h recall). Qualitative methods (5-point Likert questionnaire) were used to measure diet acceptability and side effects. RESULTS All patients completed the study. We observed highly significant decreases in BW (- 10.3%, p < 0.001, in males; - 8.2%, p < 0.001, in females), left hepatic lobe volume (- 19.8%, p < 0.001), and an amelioration of patient micronutrient status. All patients showed a high frequency of acceptability and compliance in following the diet. No adverse side effect was reported. CONCLUSION This study demonstrates that a 4-week preoperative KMED is safe and effective in reducing BW, left hepatic lobe volume, and correcting MD in obese patients scheduled for BS.

Abstract
Butyric acid (BA) has been reported to induce anticancer effects on hepatocellular carcinoma (HCC) cells both in vitro and in vivo. However, its delivery and release in cancer tissues must be optimized. On the basis of these requirements, we prepared liposomes coated with chitosan and uncoated liposomes and both types were loaded with BA through a thin-film hydration method. The liposomes coated or uncoated with chitosan had a mean hydrodynamic size of 83.5 and 110.3 nm, respectively, with a homogeneous size distribution of the particles. For evaluation of the biological effects of the nanoformulations, the hepatoblastoma (HB) HepG2 cell line was utilized. BA-loaded liposomes coated with chitosan showed a considerable higher cytotoxicity than both uncoated liposomes and free BA, with IC50 values, after 72 h of incubation, of 7.5, 2.5 and 1.6 mM, respectively. Treatment of HepG2 cells for 5 h with the BA-loaded liposomes coated with chitosan at 5 mM lowered the extent of the increase in IL-8, IL-6, TNF-α and TGF-β expression of approximately 64, 58, 85 and 73.8%, respectively, when compared to the untreated cells. The BA-loaded liposomes coated with chitosan had marked capacity to be internalized in human HB cells showing an increased cytotoxic activity when compared with free BA and important anti-inflammatory effects by inhibiting production of cytokines with a central role in liver cell survival.

Abstract
Glioblastoma multiforme is the most common and aggressive primary brain cancer with only ∼3% of patients surviving more than 3 years from diagnosis. Several mechanisms are involved in drug and radiation resistance to anticancer treatments and among them one of the most important factors is the tumor microenvironment status, characterized by cancer cell hypersecretion of interleukins and cytokines. The aim of our research was the synthesis of a nanocarrier of quercetin combined with temozolomide, to enhance the specificity and efficacy of this anticancer drug commonly used in glioblastoma treatment. The nanohydrogel increased the internalization and cytotoxicity of quercetin in human glioblastoma cells and, when co-delivered with temozolomide, contribute to an improved anticancer effect. The nanohydrogel loaded with quercetin had the ability to recognize CD44 receptor, a brain cancer cell marker, through an energy and caveolae dependent mechanism of internalization. Moreover, nanohydrogel of quercetin was able to reduce significantly IL-8, IL-6, and VEGF production in pro-inflammatory conditions with interesting implications on the mechanism of glioblastoma cells drug resistance. In summary, novel CD44 targeted polymeric based nanocarriers appear to be proficient in mediating site-specific delivery of quercetin via CD44 receptor in glioblastoma cells. This targeted therapy lead to an improved therapeutic efficacy of temozolomide by modulating the brain tumor microenvironment.

Abstract
BACKGROUND We recently showed that an 8-week preoperative protein-enriched diet (PED) is associated with significant reductions in body weight and fat mass (FM) without significant loss of fat-free mass (FFM) in morbidly obese patients scheduled for laparoscopic sleeve gastrectomy (LSG). OBJECTIVES The objective of this study is to evaluate the impact of PED vs a normal protein diet (NPD) on total weight loss (TWL), FM, FFM, and resting metabolic rate (RMR) in patients after LSG. METHODS Before LSG and at 3, 6, and 12 months after, we prospectively measured and compared total body weight (TBW), FM, FFM, and RMR in 60 male patients who received either a NPD (n = 30) with protein intake 1.0 g/kg of ideal body weight, or a PED (n = 30) with protein intake 2.0 g/kg of ideal body weight. Compliance in following the prescribed diet was determined with food frequency questionnaires in all patients. The impact of NPD and PED on renal function was also evaluated. RESULTS Despite non-significant variation in total body weight (TBW), FM decreased more significantly (p < 0.01) with the PED compared to the NPD. In addition, the PED group showed a significantly (p < 0.01) lower decrease in FFM and RMR when compared with the NPD group. Both groups showed high compliance in following the prescribed diets, without negative impact on renal function. CONCLUSION PED is more effective than NPD in determining FM loss and is associated with a lower decrease in FFM and RMR, without interfering with renal function in male patients after LSG.

Abstract
BACKGROUND Surgical site infection (SSI) is a common complication of surgical procedures. AIM Our study aimed at investigating a new method based on assessment of suture thread colonization to identify patients developing an SSI. MATERIALS AND METHODS We prospectively enrolled 119 patients undergoing elective surgery. For each patient, a synthetic absorbable thread in Lactomer 9-1 (Polisorb Gauge 2) inserted in the surgical site at the end of surgery was sent to the microbiology laboratory after 48 h to assess colonization of its inner tract. RESULTS Forty (33.6% of cases) patients had a colonized thread. Antibiotic prophylaxis was administered to 66 of 79 patients who did not display a colonized thread and to 20 of the 40 patients with a colonized thread (83.5% versus 50%, respectively, P = 0.0002). An SSI was observed only in patients with a colonized thread (10% versus 0, P = 0.02). The microorganisms identified in colonized threads were the same identified in SSIs. CONCLUSIONS Since an SSI was found only in patients with colonized threads, the method described here may be valuable for identifying patients developing an SSI. Moreover, the method can also be useful for targeting efficient antibiotic therapy to the culprit microorganisms.

Abstract
BACKGROUND There is evidence that body composition and resting metabolic rate (RMR) in weight-stable patients after Roux-en-Y gastric bypass and duodenal switch is similar to that of nonoperated individuals within the same body mass index (BMI) interval. Currently, data concerning fat mass (FM), fat-free mass (FFM), and RMR on weight-stable patients after sleeve gastrectomy (SG) are lacking. OBJECTIVES To assess FM, FFM, and RMR, in a selected and homogenous population of weight-stable SG patients (WSSG) and compare them with those obtained from healthy normal weight-stable nonoperated (WSNO) volunteers controls of similar sex, age, and BMI. SETTING University hospital, Italy. METHODS We assessed total weight, FM, and FFM by bioelectrical impedance assay, and RMR by indirect calorimetry, in 70 WSSG patients (47 females, 23 males) at a mean follow-up of 3.2 ± 2.1 years after SG and compared them with 70 healthy WSNO volunteers, as controls (47 females, 23 males). RESULTS There was no significant difference between WSSG and WSNO groups concerning total weight (males, 72 ± 2.66 versus 72.8 ± 1.99 kg, P = .0254; females 65.1 ± 2.53 versus 63.7 ± 2.87 kg, P = .0139), FM (males, 17.7 ± 1.53 versus 16.7 ± 1.57 kg, P = .0341; females 19.6 ± 0.50 versus 18.5 ± 2.85 kg, P = .0104), FFM (males, 54.3 ± 3.07 versus 56.1 ± 3.30 kg; P = .049; females 45.5 ± 2.29 versus 45.1 ± 1.13 kg, P = .287), and RMR (males, 1541 ± 121.3 versus 1463 ± 74.4 kcal/d; P = .0118; females 1214 ± 54.9 versus 1250 ± 90.1 kcal/d, P = .0215). CONCLUSION At a mean follow-up of 3.2 ± 2.1 years after SG, WSSG patients of both sexes have a FM, FFM, and RMR comparable to that of healthy WSNO individuals within the same age and BMI interval. These findings further support bariatric surgery-induced weight loss as a physiologic process and indicate that young patients, in the setting of an adequate preoperative and postoperative specific diet and moderate physical activity, do not suffer from excessive FFM depletion after SG in the mid-term.

Abstract
The aim of this study is based on the evaluation of anticancer, anti-inflammatory activities, and cellular uptake of hyaluronic acid nanohydrogel of quercetin tested alone and in combination to a macrolide derivative of rapamycin RAD001 (everolimus) on hormone-responsive breast cancer cell line MCF-7. Biological investigations were focused on the receptor mediated cellular internalization of the nanohydrogel and its abilities to reduce secretion of several cytokines (IL-8, IL-6, IL-19), VEGF, and metalloproteases (MMP-2, MMP-9) under pro-inflammatory conditions. Nanohydrogel show a CD44 dependent endocytosis with evident time dependent cytoplasmatic accumulation with abilities to reduce secretion of all cytokines of ∼60% compared to untreated cells. Combination of formulated quercetin and everolimus leads to a synergistic cytotoxic effects with a Combination Index of 0.38. These results highlights the importance of synergistic effect of the hyaluronic acid nanohydrogel of quercetin with everolimus in the regulation of human breast cancer cell proliferation and emphasize the antitumor and anti-inflammatory properties of the nanocarrier.

Abstract
Bariatric surgery candidates often show preoperative micronutrient deficiency. Although it is documented that a comprehensive micronutrient assessment should be conducted preoperatively to correct the deficiencies before surgery, no previous studies have been effective in correcting deficiencies in sufficient time prior to surgery. Our aim was to identify micronutrient deficiencies preoperatively and correct them before surgery.

Abstract
INTRODUCTION Giant inguinoscrotal hernias are unusual in developed countries and rarely associated with other wall hernias, such as controlateral inguinal hernia, umbilical hernia. The presence of more parietal defects can facilitate reinstatement of giant hernia content without respiratory and circulatory compromise, but the risk of occlusion and bowel strangulation results increased. CASE REPORT Here, we report an unusual case of an asymptomatic giant inguinal hernia associated with controlateral inguinal and umbilical hernia in a 60 years old Caucasian male treated with sequential surgical approach. In particular, the Lichtenstein's technique under spinal anesthesia was performed and it could be considered the gold standard for this disease. CONCLUSION Giant inguinal hernia and abdomen wall defects should not be repaired at the same time. It is more useful to be less aggressive, monitoring the progressive and natural adaptation of the viscera into the abdomen. Anyway, thereby literature results very poor and additional reports are required. KEY WORDS Giant inguinoscrotal hernia, Hernia, Hernia treatment, Wall defects.

Abstract
INTRODUCTION Insulin resistance (IR), leptin resistance (LR), and polycystic ovary syndrome (PCOS) commonly coexists with obesity. IR and PCOS are often successfully treated with the use of insulin-sensitizing drugs (ISDs). However, some women are poorly responsive or intolerant to them. If we additionally consider that currently no medical treatment for LR exists, it is crucial for the physician to find different therapeutic ways to treat patients with such multifactorial endocrinopathy. PRESENTATION OF CASE We present a case where sleeve gastrectomy (SG) was applied to a 27-year-old obese woman affected by concomitant IR, LR and PCOS, and unresponsive to ISDs. At three years from surgery the patient is now 71.6kg. More importantly, her levels of insulin and leptin started to improve at postoperative month 6 and became normal at postoperative month 24. Patient's ovaries that at baseline had characteristic aspects related to PCOS, at postoperative month 36 were normal. DISCUSSION SG is one of the most commonly performed bariatric procedures. The literature has moved away from labeling SG as a purely restrictive procedure, as its interactions with several hormones (ghrelin, leptin, insulin, etc.) are now recognized. CONCLUSION In the present report, SG was applied to resolve an intricate endocrinological framework confirming its therapeutic value not only in determining weight loss but also as endocrine/metabolic surgery able to treat multifactorial endocrinopathy. The underlying molecular mechanisms contributing to these benefits remain largely undetermined, despite offering tremendous potential to reveal new targets for therapeutic intervention, mostly in those patients unresponsive to classical pharmacotherapy.

Abstract
BACKGROUND Weight loss before laparoscopic sleeve gastrectomy (LSG) is desirable because it can reduce visceral fat and liver size thereby facilitating the surgical procedure. Preoperative very-low-energy diets have been demonstrated to decrease weight, visceral fat, and liver size. However, no studies have been conducted using the Mediterranean-protein-enriched diet (MPED) or on the amount of preoperative weight loss attributed to the loss of fat-free mass (FFM). OBJECTIVES To evaluate the effect of the MPED on weight, visceral fat, liver size, fat mass (FM), and FFM in obese patients undergoing LSG. SETTING University Hospital, Italy. MATERIALS AND METHODS Obese male patients (n = 37) with a mean body mass index (BMI) of 45.2 kg/m(2) scheduled for LSG underwent an 8-week preoperative MPED. Their weight, visceral fat, body composition, liver size, and biochemical and metabolic patterns were measured before and after the diet. Patient compliance was assessed by the presence of ketonuria and weight loss. Qualitative methods (5-point Likert questionnaire) were used to measure diet acceptability and side effects. RESULTS We observed highly significant decreases in weight, liver size, visceral fat, and FM; however, there was no significant reduction in FFM. All tested patients showed a high frequency of acceptability and compliance in following the diet, and no secondary effects were observed. CONCLUSION Based on our findings, we were able to support the hypothesis that MPED might be associated with significant reductions in weight loss, FM, and liver size without a significant loss of FFM.

Abstract
BACKGROUND Although D2 lymphadenectomy has been shown to improve outcomes in gastric cancer, it may increase postoperative morbidity, mainly owing to splenopancreatic complications. In addition, the effects of nodal dissection along the proper hepatic artery have not been extensively elucidated. We hypothesized that modified D2 (ie, D1+) lymphadenectomy may decrease surgical risks without impairing oncologic adequacy. METHODS Patients with node-positive gastric cancer undergoing curative total gastrectomy were intraoperatively randomized to D1+ (group 1, 36 patients) or standard D2 lymphadenectomy (group 2, 37 patients), the latter including splenectomy and nodal group 12a. The index of estimated benefit was used to assess the efficacy of dissection of each nodal station. The primary endpoint for oncologic adequacy was the disease-free survival (DFS) rate. RESULTS Surgical complications were significantly more common in group 2, which also included 2 postoperative deaths. Overall, 35 patients (49%) experienced tumor recurrence. The primary site of tumor relapse and the 5-year DFS rate were not different between the 2 groups. Involvement of the second nodal level was associated with a worse DFS rate; however, patients undergoing more extensive lymphadenectomy did not show a better DFS rate. The incidence of involvement of nodal stations 10, 11d, and 12a was 5%, and the 5-year DFS rate was zero. Consequently, the benefit to dissect such lymph nodes was null. CONCLUSION These findings suggest that modified D2 lymphadenectomy confers the same oncologic adequacy as standard D2 lymphadenectomy, with a significant reduction of postoperative morbidity.

Abstract
Adipose tissue is an easily accessible source of stem cells for use in tissue regenerative medicine. In the literature, different methods have been used to stimulate acquisition of neuronal characteristics by adipose-derived stem cells (ADSC). Herein we study the growth and neuronal differentiation potential of ADSC seeded onto a porous polycaprolactone (PCL) scaffold. The objective of this study is to demonstrate that PCL can be used as a scaffold to support reconstruction of new nervous tissue using adipose stem cells. We have previously shown that undifferentiated ADSC adhere and grow on PCL. Herein we show that, after culture on PCL in neuronal differentiation medium, ADSC expressed molecular markers characteristic of neuronal cells (β-tubulin-III, Neuron-Specific Enolase (NSE), Nestin) and secrete brain derived neurotrophic factor (BDNF) and nerve growth factor (NGF). This study suggests that PCL can be used as a scaffold to generate nervous tissue in vitro. PLC has excellent mechanical properties and a slow degradation rate. Moreover, on the basis of our results, we propose that PCL could be used for to make in vitro, scaffold coated with neuronal cells derived from Adipose stem cells (ADSC). Neuronal cells-coated PCL could find several applications to replace damaged area of the body; for example, a possible use could be the generation of nerves.

Abstract
Increased insulin-like growth factor (igf) signalling has been observed in breast cancer, including endocrine-responsive cancers, and has been linked to disease progression and recurrence. In particular, igf-1 has the ability to induce and promote lymphangiogenesis through the induction of vascular endothelial growth factor C (vegfc). In the present study, we analyzed serum and tumour samples from 60 patients with endocrine-positive breast cancer to determine the expression and the possible relationship of circulating igf-1, igf binding protein 3 (igfbp3), and vegfc with the presence of lymphatic metastasis and other immunohistochemical parameters. The analysis revealed a clear and significant correlation between high basal levels of igf-1, igfbp3, and vegfc and lymph node metastasis in endocrine-responsive breast cancer. In addition, expression of those molecules was significantly higher in breast cancer patients than in healthy control subjects. Those findings may enable more accurate prediction of prognosis in patients with breast cancer.

Abstract
This paper focused on the biodistribution of the cross-linked hyaluronic acid (HA-NPs) sub-micron particles in tumor-bearing mice. Solvent-non solvent method followed glutaraldehyde cross-linking utilized for the fabrication of HA-NPs. Size measurement and morphological analysis were performed by dynamic light scattering and electron microscopy, respectively and the size found to be in the range of 200-400 nm. In vitro viability in LNCaP cell line was assessed by water soluble tetrazolium assay after 24 h of exposure to sub-micron particles and no toxicity was found to higher concentration of 3 mg/mL. Internalization of particles in prostate cancer cell LNCaP were studied by confocal microscopy with FITC labeled submicron particles and involvement of hyaluronan receptor mediated uptake/endocytosis was confirmed by competitive assay. Biodistribution studies were performed in xenograft prostate cancer mice model with fluorophore labeled particles and monitored in tumoral parenchyma with strong fluorescence, meanwhile very less signal in liver, kidney and spleen while no fluorescence found in lung after 24 h of systemic administration; that shown ability of this HA based system to recognize cancer tissue. These result fetched that hyaluronic acid based system is selective for tumoral site and can be utilized to deliver bioactives in specific (targeting) and controlled (temporal) manner to cancerous tissue.

Abstract
BACKGROUND An ulcer is a trophic lesion with loss of tissue that often has a multifactorial genesis. It typically diverges from the physiologic processes of regeneration because it rarely tends to heal spontaneously. In this study, we used purified adipose-derived stem and regenerative cells (ADRCs) extracted from autologous fat, for the care of chronic ulcers of the lower limbs of arteriopathic patients. The primary objective of this study was complete re-epithelization of chronic ulcers; the secondary objective was a decrease in diameter and depth. METHODS From January 2010 to January 2012, 20 patients with peripheral arterial disease, with an ankle-brachial index between 0.30-0.40, in the age range 60-70 y (14 men and six women), with chronic ulcers of the lower limb, were involved in the study. Only 10 arteriopathic patients (seven men and three women) with chronic ulcers of the lower limb were surgically treated. Using the Celution system, we isolated a solution of ADRCs in about 150 min. The isolated cells were injected through a 10-mL syringe into the edges of the ulcer, taking care to spread it in all directions. Using a small amount of Celution extract, we performed cell characterization by flow cytometry analysis and cell viability assay. RESULTS We monitored patients treated with ADRC or untreated at 4, 10, 20, 60, and 90 d. In all cases treated with ADRC, we found a reduction in both diameter and depth of the ulcer, which led to a decrease in pain associated with the ulcer process. In six of 10 cases there was complete healing of the ulcer. Characterization of the cells by FACS clearly showed that the ADRC cells contained adipose-derived stem cells. Viability assays demonstrated that partial or total closure of the ulcer was attributable exclusively to ADRC cells present in the Celution extract, and not to growth factors extracted during the process of purification of the Celution and injected together with the cells. CONCLUSIONS For the first time, the Celution method has been applied for the care of chronic ulcers in the lower extremity of patients with peripheral arterial disease. Our results demonstrate that the technique is feasible for autologous cell application and is not associated with adverse events. Moreover, the transplantation of autologous stem cells extracted with Celution may represent a valuable method for the treatment of chronic ulcers in lower limbs of arteriopathic patients.

Abstract
Thyroid cancer is not very common, accounting for 1-2% of all cancers, with a population incidence of about 0.004%. Currently, the ability to discriminate between follicular adenoma and carcinoma represents the major challenge in preclinical diagnosis of thyroid proliferative lesions. Better discrimination between the two would help avoid unnecessary thyroidectomy and save valuable resources. Over the years, galectin-3 (Gal-3) has been proposed as a diagnostic marker with varied success. In this paper, we used Environmental Scanning Electron Microscopy Immunogold Labelling (ESEM-IGL) to investigate the expression of Gal-3 on Thin-Prep fine needle aspiration cytology (FNAC). We optimized the ESEM-IGL method on thyroid cell lines (RO-82 and FTC-133) comparing our membrane Gal-3 labeling data with Western blot. We evaluated 183 thyroid FNAC from Italian patients with a uncertain pre-surgical diagnosis. ESEM-IGL method marker sensitivity is 71.2%, while specificity is 53.3% and diagnostic efficacy is 61.2%. Our results confirmed that Gal-3 expression is associated with situations of hypertrophy and/or cellular hyperproliferation, pathophysiological situations common both to adenomas and to thyroid carcinomas. The innovation of thyroid FNAC Thin-Prep ESEM-IGL shows the levels of Gal-3 immunolabeling clearly, even through the individual cells of a thyroid nodule. However, Gal-3 alone, as a molecular marker of thyroid cancer, can still have a limited application in pre-surgery diagnosis.

Abstract
Adipose tissue is a readily available source of multipotent adult stem cells for use in tissue engineering/regenerative medicine. Various growth factors have been used to stimulate acquisition of endothelial characteristics by adipose-derived stem cells (ADSC). Herein, we study the growth and endothelial differentiation potential of ADSC seeded onto a porous polycaprolactone (PCL) scaffold. The objective of this study is to demonstrate that PCL is a good material to be used as a scaffold to support reconstruction of new endothelial tissue using adipose stem cells. We found that undifferentiated ADSC adhere and grow on PCL. We show that, after culture in endothelial differentiation medium, ADSC were positive to LDL uptake and expressed molecular markers characteristic of endothelial cells (CD31; eNOS and vWF). In addition, our study defines the time required for the differentiation of ADSC directly onto PCL. This study suggests that PCL can be used as a scaffold to generate endothelial tissue in vitro. PLC has excellent mechanical properties and a slow degradation rate. Moreover, based on our results, we propose that PCL could be used to graft scaffolds coated with endothelial cells derived from ADSC stem cells. Endothelial cells-coated PCL could find several applications to replace damaged area of the body; for example, a possible use could be the generation of vascular grafts.

Abstract
BACKGROUND The postoperative hypoparathyroidism is a not rare complication after total thyroidectomy and/or total parathyroidectomy. Attempts to transplant parathyroid tissue began in 1975 with the work of Wells, but still today results are disappointing. However, with the development of tissue engineering techniques, some experimental approaches to build artificial parathyroid are been made. Bioengineered device, actively secreting PTH, for transplant in patients with iatrogenic hypoparathyroidism is unavailable. PATIENTS AND METHODS Parathyroid cells were obtained from three chronic uremic patients in hemodialysis, operated for secondary hyperparathyroidism. Cell cultures in RPMI medium were subsequently seeded on collagen scaffold (three-dimensional matrix with slow biodegradation). Collagen is the major component of the extracellular matrix and thus is a good substrate for cell adhesion and growth. Culture media, with a low calcium concentration, were optimised to physiologically stimulate parathyroid hormone secretion. Cell cultures were morphologically observed in optical and electron (ESEM) microscopy and metabolically assayed by MTT method until the tenth week. Besides, concentration of parathyroid hormone in the culture medium has been measured for several weeks. RESULTS After 24 hours of culture in RPMI, cells extracted from human parathyroid glands were nearly all adherent and organised in clusters to resemble the glandular organization. The cellular population consisted predominantly of parathyroid cells (90-95%). On collagen scaffolds, cells maintains an epithelial-like morphology also after 10 weeks, colonizing the scaffold surface and keeping a good proliferative rate with a discrete production of parathyroid hormone. CONCLUSION The use of parathyroid cells extracted from patients with secondary hyperparathyroidism was certainly an appropriate choice that enabled us to achieve these results, that albeit partial bode well for the experimental in vivo animal model. The bioengineered scaffolds when implanted in the subcutaneous can avoid the dispersion of parathyroid cells, assuring also the possibility to easily remove the implant in case of complications. Our research was aimed primarily to the optimisation of PTH secreting human parathyroid cells cultures and then to the in vitro engineering of human parathyroid glands in three-dimensional collagen scaffolds.

Abstract
The gene encoding a novel alcohol dehydrogenase (ADH) that belongs to the medium chain dehydrogenase/reductase (MDR) superfamily was identified in the hyperthermophilic archaeon, Pyrobaculum aerophilum. The P. aerophilum ADH gene (Pae2687) was over-expressed in Escherichia coli, and the protein (PyAeADHII) was purified to homogeneity and characterized. The PyAeADHII belongs to a medium chain class because its monomer size is 330 residues and even if it is structurally similar to other enzymes belonging to MDR superfamily, it lacks key residues involved in the coordination of the catalytic Zn ion and in the binding of alcoholic substrates typical of other ADHs. Consistently, PyAeADHII does not show activity on a large number of alcohols, aldheydes or ketones. It is active only when alpha-tetralone is used as a substrate. The enzyme has a strict requirement for NADP(H) as the coenzyme and has remarkable thermophilicity, displaying activity at temperatures up to 95 degrees C. The study of the metabolic pathways of P. aerophilum can provide information on the evolution of genes and enzymes and may be crucial for understanding the evolution of eukaryotic cells.

Abstract
Human adipose tissues surgically resected from the subcutaneous abdominal region were enzymatically processed to obtain Human Adipose Stem cells (fibroblast-like adipose tissue-derived stromal cells-ADSC-FL) that were immunophenotypically characterized using a panel of mesenchymal markers by flow cytometry. The formation of new hydroxyapatite crystals in culture dishes, by differentiating cells, further demonstrate the osteogenic potential of purified cells. The aim of this study was to evaluate the osteogenic differentiation potential of ADSC-FL seeded onto a porous beta-tricalcium phosphate (beta-TCP) matrix. ADSC-FL was cultured on the beta-TCP matrix in medium with or without osteogenic differentiation additives. Time-dependent cell differentiation was monitored using osteogenic markers such as alkaline phosphatase (activity assay), osteocalcin and ostopontin (ELISA method) expression. Our results reveal that beta-TCP triggers the differentiation of ADSC-FL toward an osteoblastic phenotype irrespective of whether the cells are grown in a proliferative or a differentiative medium. Hence, a beta-TCP matrix is sufficient to promote osteoblastic differentiation of ADSC-FL. However, in proliferative medium, alkaline phosphatase activity was detected at lower level respect to differentiative medium and osteocalcin and osteopontin showed an expression delay in cells cultured in proliferative medium respect to differentiative one. Moreover, we observed an increase in FAK phosphorylation at level of tyrosine residue in position 397 (Western-blot) that indicates a good cell adhesion to beta-TCP scaffold. In conclusion, our paper demonstrates that a three-dimensional beta-TCP scaffold in vitro triggers on its own the differentiation of ADSC-FL toward an osteoblastic phenotype without the need to use differentiative media.

Abstract
UNLABELLED Breast surgery is classified among the procedures performed in clean surgery and is associated with a low incidence of wound infection (3-15%). The objective of this study was to evaluate the advantages antibiotic prophylaxis in patients undergoing breast surgery. A multicenter randomized controlled study was performed between January 2008 and November 2008. One thousand four hundred patients were enrolled in prospective randomized study; surgical wound infection was found in 41 patients (2.93%). In our RCT we have shown that in breast surgery antibiotic prophylaxis does not present significant advantages in patients with potential risk of infection (17 patients, 2.42%, subjected to antibiotic prophylaxis vs 24 patients, 3.43%, without antibiotic prophylaxis) (P = 0.27). In patients with drainage there is a significant minor incidence of wound infections in patients receiving antibiotic prophylaxis (5 patients, 0.92%, subjected to antibiotic prophylaxis vs 14 patients, 3.09%, without antibiotic prophylaxis) (P = 0.02). CONCLUSION This study is only a preliminary RCT to be followed by a study which should be enrolled more patients in order to get the results as statistically significant.

Abstract
INTRODUCTION We carried out a retrospective analysis of our experience in the management of Differentiated Thyroid Carcinoma (DTC), in order to better define prognostic factors (age, gender, histological type, stage) and outline a standard procedure, where it's possible, for surgical treatment. PATIENTS AND METHODS Patient population consisted of 432 cases, operated from 1978 to 2003. We carried out 285 operations of total thyroidectomy of which 39 associated to some kind of lymphadenectomy, 66 totalization (21 pts had been operated in other institutes), 60 subtotal thyroidectomies and 21 lobo-isthmectomies. Survival and mortality curves for age, sex, histological type, grading and staging have been calculated. Kaplan-Meyer statistical elaboration for disease-free interval and Mann-Whitney test for the comparison of different clinical and pathological data have been employed. RESULTS The statistical analysis puts in evidence that on 432 cases examined, with a follow-up from 1 to 25 ys (median = 6.33 ys) and with a drop-out of 60 cases (13.8 %), total mortality for cancer has been of 24 cases (6,4%), with a median interval free by disease of 4.2 ys (range 5 months to 25 ys), and a probability to stay free by disease at 12 and 24 months respectively of 95.1% and 91.6%. The median survival is resulted of 5.8 ys (range 1 to 25 ys) with a probability of survival at 24 and 48 months respectively of 97.5% and 94.3%. The multivariate analysis evidences the most important variables, i.e. age > 45 ys, tumor of intermediate malignancy, with size 1.5 cm, operative M+, significantly condition the prognosis, noticeably getting worse it, independently by the kind of carried out operation. CONCLUSION Our present therapeutic choices are: 1. total thyroidectomy in the treatment of the apparently benign pathology when bilaterally with spread; the checking at the final histological exam of a cancer makes however think adequate the carried out operation; 2. lobo-isthmectomy in the treatment of unilateral benign pathology or with suspect FNAB for follicular neoplasm; the histological checking of a cancer makes think the operation adequate only in presence of favourable prognostic parameters, but in presence even of just one unfavourable variable, we consider necessary the totalization; 3. total thyroidectomy in presence of a certain or strongly suspected preoperative diagnosis of cancer.

Abstract
In this work we used a combination of immunogold labelling (IGL) and environmental scanning electron microscopy (ESEM) to detect the presence of a protein on the cell surface. To achieve this purpose we chose as experimental system 3T3 Swiss Albino Mouse Fibroblasts and galectin-3. This protein, whose sub-cellular distribution is still under discussion, is involved in a large number of cell physiological and pathological processes. IGL technique has been utilised by many authors in combination with SEM and TEM to obtain the identification/localisation of receptors and antigens, both in cells and tissues. ESEM represents an important tool in biomedical research, since it does not require any severe processing of the sample, lowering the risk of generating artefacts and interfere with IGL procedure. The absence of metal coating could yield further advantages for our purpose as the labelling detection is based on the atomic number difference between Nanogold spheres and the biological material. Using the gaseous secondary electron detector (GSED) compositional contrast is easily revealed by the backscattered electrons component of the signal. In spite of this fact, only few published papers present a combination of ESEM and IGL. Hereby we present our method, optimised to improve the intensity and the specificity of the labelling signal, in order to obtain a semi-quantitative evaluation of the labelling signal.

Abstract
Recent studies, on cells cultured in 3D collagen gels, have shown that, beside from their well known biochemical role, fibronectin (FN) and laminin (LM) affect cell functions via a modification of mechanical and structural properties of matrix due to interaction with collagen molecules. Though biochemical properties of FN and LM have been widely studied, little is known about their role in collagen matrix assembly. The aim of this work was to characterize FN- and LM-based collagen semi-interpenetrating polymer networks (semi-IPNs), in order to understand how these biomacromolecular species can affect collagen network assembly and properties. Morphology, viscoelasticity and diffusivity of collagen gels and FN- and LM-based collagen semi-IPNs were analysed by Confocal Laser Scanning microscopy (CLSM), Environmental Scanning Electron microscopy (ESEM), Transmission Electron microscopy (TEM), Rheometry and Fluorescence Recovery After Photobleaching (FRAP) techniques. It was found that FN and LM were organized in aggregates, interspersed in collagen gel, and in thin fibrils, distributed along collagen fibres. In addition, high FN and LM concentrations affected collagen fibre assembly and structure and induced drastic effects on rheological and transport properties.

Abstract
Carcinoma of the pancreas is extremely common, with a five-year mortality rate of about 95-99%. Radical surgery requires good technical skill and can cause complications and operative mortality, but should be avoided in patients with extrapancreatic involvement. Advances in dynamic spiral CT-scan have decreased the number of unnecessary laparotomies. VLS is indicated in cases of pancreatic mass deemed resectable or "doubtful" by CT-scan. Direct laparoscopic visualization can be combined with intraoperative laparoscopic ultrasonography (LUS), which has shown a positive predictive value of resectability of 91%. Laparoscopic pancreatoduodenectomy (LPD) shows a high rate of complications and should be performed by very well-trained surgeons. Laparoscopic distal pancreatectomy (LDP) with an "en bloc" splenectomy and spleen preservation should be performed.

Abstract
The purpose of our study was to evaluate the presence of anatomical and functional damage to the afferent and sensorial fibres using the Neurometer CPT test. A questionnaire regarding pain was sent to 300 women who had undergone surgery six months earlier. Out of 300 patients 67 did not respond; 105 experienced no pain; while 128 felt pain. One hundred and twenty-eight women were divided into two groups: mastectomy with reconstruction and simple mastectomy. The intensity of pain at T0 in women with reconstruction was significantly higher; at T4, on the other hand, was lesser and there was no significant difference between the two groups. In both groups at T4, the daily diary revealed that interference with sleep and normal daily activities were more evident in patients who had undergone reconstruction (p > 0.001). The final results at T4 demonstrated that among patients with reconstruction, 47% showed slight hypoesthesia-paraesthesia in the breast, armpit and arm zones, 39% slight hypoesthesia in the same locations and 18% severe hypoesthesia. Patients with reconstruction, instead, showed different percentages: 75% showed slight hypoesthesia-paraesthesia, 16% a slight hypoesthesia and 9% severe hypoesthesia. Our results support the utilization of the Neurometer CPT test as a device for monitoring post-mastectomy pain.

Abstract
A retrospective study was carried out to assessed reliability of the prognostic factors (histology, age, sex, and stage), and standard procedures for the surgical treatment of differentiated thyroid cancers (DTC). From the 144 DTC cases reviewed with follow-up ranging from 1 to 25 years (m = 6.33 years), total mortality for cancer was found to be 55% (8 patients), with a predictive positive value for recurrence of 95.4% and 91.8% at 12 and 24 months, respectively. Median survival was 8.8 years (range 1 to 25 years). The multivariate analysis showed that factors such as age > 45 years, histology of intermediate malignancy, size up to 1.5 cm, and presence of metastases, significantly worsened the prognosis, regardless of the intervention that was carried out. We suggest total thyroidectomy for the treatment of benign pathologies and confirmed or suspected cases of cancer. We reserve loboisthmectomy for the treatment of benign pathologies confined to one lobe or those with FNAB suggesting a follicular neoplasm.

Abstract
Scanning Electron Microscope (SEM) is a powerful research tool, but since it requires high vacuum conditions, the wet materials and biological samples must undergo a complex preparation that limits the application of SEM on this kind of specimen and often causes the introduction of artifacts. The introduction of Environmental Scanning Electron Microscope (ESEM), working in gaseous atmosphere, represented a new perspective in biological research. Despite the fact that many biological applications have demonstrated the convenience of ESEM, the full potentialities of this technology are still under investigation. In this review, the exploration of the recent literature data confronted with the first results obtained in our experimental work suggest that ESEM represents an important extension of conventional scanning microscopy.

Abstract
We used combined plasma-deposition process to deposit smooth and nanostructured fluorocarbon coatings on polyethylenethereftalate (PET) substrates, to obtain surfaces with identical chemical composition and different roughness, and investigate the effect of surface nanostructures on adhesion and proliferation of 3T3 Swiss Albino Mouse fibroblasts. Untreated PET and polystyrene (PS) were used as controls for cell culture. We have found that the statistically significant increase of cell proliferation rate and FAK (a nonreceptor tyrosine kinase) activation detected on ROUGH fluorocarbon surfaces is due to the presence of nanostructures. Changes in cytoskeletal organization and phospho FAK (tyr 397) localization were evident after 60 min on cells adhering to ROUGH surfaces. This change was characterized by the formation of actin stress fibers along lamellar membrane protrusion instead of usual focal contacts. Also the morphology of the adhering fibroblasts (60 min) adhering on ROUGH surfaces was found quite different compared to cells adhering on smooth ones.

Abstract
In this review, we focused our attention on the more important natural extracellular matrix (ECM) molecules (collagen and fibrin), employed as cellular scaffolds for tissue engineering and on a class of semi-synthetic materials made from the fusion of specific oligopeptide sequences, showing biological activities, with synthetic materials. In particular, these new "intelligent" scaffolds may contain oligopeptide cleaving sequences specific for matrix metalloproteinases (MMPs), integrin binding domains, growth factors, anti-thrombin sequences, plasmin degradation sites, and morphogenetic proteins. The aim was to confer to these new "intelligent" semi-synthetic biomaterials, the advantages offered by both the synthetic materials (processability, mechanical strength) and by the natural materials (specific cell recognition, cellular invasion, and the ability to supply differentiation/proliferation signals). Due to their characteristics, these semi-synthetic biomaterials represent a new and versatile class of biomimetic hybrid materials that hold clinical promise in serving as implants to promote wound healing and tissue regeneration.

Abstract
Copolymerisation of charged and neutral monomers is a well-known methodology to introduce charged moieties in a polymeric chain to obtain polyelectrolytes. New polyelectrolyte complexes have been synthesised by radical copolymerisation of neutral methacrylic monomer 2-hydroxyethyl methacrylate (HEMA) with cationic 2-methacryloyloxyethyltrimethyl ammonium chloride and anionic 2-acrylamido-2-methylpropane-sulphonic acid monomers in 10:1:1 and 10:1:2 stechiometric ratio. Chemical structure of the synthesised terpolymers was confirmed by FT-IR spectroscopy, moreover, X-ray photoelectron spectroscopy showed the presence of a cationic charge excess on the 10:1:2 terpolymer surface with respect to 10:1:1 terpolymer. Swelling studies for 10:1:2 terpolymers showed a high water content in the swollen state and a "smart behaviour" upon changes in external stimuli such as pH, while, 10:1:1 terpolymer presented the behaviour of a neutral polymer. Mechanical and differential scanning calorimetry analysis confirmed that terpolymer networks were stabilised by ionic co-operative interactions. Infact, the inclusion of oppositely ionic charges in the polymeric network of p(HEMA) represent a way to achieve higher elastic modulus as they stabilise the terpolymer networks. Cytotoxicity and cytocompatibility studies demonstrated that all materials were not toxic, moreover, the presence of a cationic charge excess on 10:1:2 terpolymer surface was able to promote fibroblast adhesion.

Abstract
The extracellular matrix (ECM) consists of a complex mixture of structural and functional macromolecules and serves an important role in tissue and organ morphogenesis and in the maintenance of cell and tissue structure and function. The great diversity observed in the morphology and composition of the ECM contributes enormously to the properties and function of each organ and tissue. The ECM is also important during growth, development, and wound repair: its own dynamic composition acts as a reservoir for soluble signaling molecules and mediates signals from other sources to migrating, proliferating, and differentiating cells. Approaches to tissue engineering center on the need to provide signals to cell populations to promote cell proliferation and differentiation. These "external signals" are generated from growth factors, cell-ECM, and cell-cell interactions, as well as from physical-chemical and mechanical stimuli. This review considers recent advances in knowledge about cell-ECM interactions. A description of the main ECM molecules and cellular receptors with particular care to integrins and their role in stimulation of specific types of signal transduction pathways is also explained. The general principles of biomaterial design for tissue engineering are considered, with same examples.

Abstract
BACKGROUND The classification, diagnostic recognition and surgical treatment of breast lesions at risk of neoplastic transformation represent some of the most important objectives in breast research. Attention has been focused on lesions at risk of neoplastic transformation in breast pathology, such as: atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), multiple intraductal papilloma and sclerosing adenosis. METHODS Our experience regards activity carried out from 1996 to 2001; the diagnostic approach included routine performance of echotomographic examination, mammography screening indicated in women >40 and, in selected cases, in women <40; FNAB was carried out in all lesions containing suspicious cells. In the case of non-palpable lesions we carried out a CT-guided FNAB using the stereotaxic technique. In cases of secreting breast, galactography proved useful. As regard clinically suspect nipple secretions, cytology was useful in the diagnosis of intraductal papillomatous lesions. Surgery was indicated for: mammographically negative nodular lesions with cytological finding of suspect lesions. Continuous, spontaneous mono-orificial, serous, sero-hematic or hematic secretion of the nipple also in the presence of negative and/or inconclusive galactographic and cytological findings. From a nosological viewpoint we have distinguished 3 groups: A) 49 women (average age 47.3 years) with suspect lesions subjected to biopsy. On the basis of the cytological response we carried out: 37 quadrantectomies with extemporary examination, 4 excisional biopsies, 5 radical ductectomies and 3 microductectomies. B) 26 patients (36.7 years) subjected to mammary biopsy for non-suspect lesions; in 24 cases excisional biopsy of the lesion and in 2 cases radical ductectomy. C) Control group consisting of 141 women (average age 44.5 years) suffering from benign pathology not suspected of lesions at risk and not subjected to surgery. RESULTS The final histological examination evidenced: Group A: 7 cases of T1aN0M0 carcinoma (14.3%); 20 lesions at risk (40.8%); 22 lesions not at risk; Group B: 25 (96.1%) lesions not considered at risk, in 1 case (3.9%) area of sclerosing adenosis with ductal proliferation and slight atypias; Group C: in 4 cases (3.1%) the onset at follow-up of lesions at risk made it necessary to remove the lesion. Histology did not confirm the presence of cancer in any case. CONCLUSIONS The diagnostic and therapeutic protocol proposed enables us to identify and radically treat high risk patients (Group A) and follow them up closely. On the contrary, Group B evidenced a very low incidence of lesions at risk which escaped preoperative diagnosis and in confirmation of this in Group C, during follow-up, the onset of only 4 lesions at risk was identified in which histological examination however excluded the presence of cancer.

Abstract
Quality-of-life assessment is becoming an important concern even of surgeons. The new trend applies specifically to surgical oncology, where particular attention is now being paid to the outcome of surgical treatment. Gastrointestinal cancers are heterogeneous in their presentation and in treatment, but they share common aspects related to the surgical approach. A functional outcome is fundamental in all the operations performed for gastrointestinal cancers and many improvements have been made thanks to the increased rate of conservative approaches and the amelioration of the technology applied to surgery. The measurement of the surgical outcome and the methods to be applied is still undergoing extensive evaluation but the flourishing interest in the issues concerning quality of life all over the surgical community will rapidly lead to a better definition of goals and results.

Abstract
UNLABELLED A phase II trial was undertaken to test the activity and toxicity of carboplatin (300 mg/m2, i.v. day 1) + epirubicin (75 mg/m2, i.v. day 1) + VP-16 (100 mg/m2, i.v. days 1 to 3) + lenograstim (5 mcg/kg, s.c. days 6 to 15) administered every 3 weeks for 4 cycles and subsequent chest irradiation (50 Gy) + daily carboplatin (25 mg/m2) in the first-line treatment of adults affected by limited small cell lung cancer (SCLC). PATIENTS AND METHODS A single-stage phase II design was used; the complete response (CR) rate after chest radiotherapy was the primary end-point. Twenty-three CRs were required out of 38 patients to consider the treatment worthy of further study. Prophylactic cranial irradiation (PCI) was planned in case of CR. Patients aged < or = 70 were eligible if they had limited SCLC, a performance status not worse than 2 by the ECOG scale and no prior chemotherapy or radiotherapy. RESULTS From January 1995 to April 1999, 33 patients were enrolled; the median age was 60 years. All the patients started chemotherapy; 23 patients received chest irradiation and concurrent daily carboplatin; 11 patients also received PCI. Toxicity was generally mild. Sixteen CRs (48.5%, 95% CI: 30.8-66.5) were recorded; the objective response rate was 72.7% (95% CI: 54.5-86.7). The median time-to-progression was 7.9 months (95% CI: 6.5-10.4). The median-survival was 10.7 months (95% CI: 9.2-16.1). CONCLUSION Induction chemotherapy with carboplatin + epirubicin + VP-16 followed by chest irradiation plus concurrent daily carboplatin is well-tolerated but not sufficiently active to warrant further study in the treatment of patients with limited SCLC.
