Potential biomarkers as a predictive factor of response to primary chemotherapy in breast cancer patients.

In this study, we identified miRNAs and their potential mRNA targets that are intricately linked to primary chemotherapy response in patients with invasive ductal carcinomas. A cohort of individuals diagnosed with advanced invasive breast ductal carcinoma who underwent primary chemotherapy served as the cornerstone of our study. We conducted a comparative analysis of microRNA expression among patients who either responded or did not respond to primary systemic therapy. To analyze the correlation between the expression of the whole transcriptome and the 24 differentially expressed (DE) miRNAs, we harnessed the extensive repository of The Cancer Genome Atlas (TCGA) database. We mapped molecular mechanisms associated with these miRNAs and their targets from TCGA breast carcinomas. The resultant expression profile of the 24 DE miRNAs emerged as a potent and promising predictive model, offering insights into the intricate dynamics of chemotherapy responsiveness of advanced breast tumors. The discriminative analysis based on the principal component analysis identified the most representative miRNAs across breast cancer samples (miR-210, miR-197, miR-328, miR-519a, and miR-628). Moreover, the consensus clustering generated four possible clusters of TCGA patients. Further studies should be conducted to advance these findings.

In vitro fertilization: an unexpected finding in a cohort of patients with biliary atresia.

In biliary atresia (BA), efforts to prevent premature liver transplantation (LT) are aimed at early diagnosis, timing of Kasai-portoenterostomy (KPE), and centralization of care. This report presents the clinical picture, treatment strategies, and outcomes of BA patients with no previous treatment. A retrospective cohort study (Jan/2001 to Jan/2021) was conducted to evaluate the outcome of patients with BA referred to a single team. Study groups were: 1) Kasai-only group (K-only) n=9), 2) LT-only group (n=7), and 3) Kasai+LT group (K+LT) (n=23). Survival with native liver and overall survival were 22.9 and 94.8%, respectively, at 120 months of follow-up. There was no difference in age at KPE in the K-only group (46.8±21.8 days) vs K+LT (52.1±22 days), P=0.4. Ten (25.6%) patients were babies conceived through in vitro fertilization (IVF). Four IVF patients (40%) presented associated congenital heart disease vs 5 patients (17%) in the remaining group (P=0.14). Two of the IVF patients were premature (<37 weeks). Median maternal age at birth was 35 years (33 to 41 years). Excellent patient survival is expected for patients with BA with the available treatment strategies. IVF+BA was an unexpected prevalent association in this cohort, and further studies are required to better understand these findings.

Surgical coaching applied to laparoscopic TME for continuous professional development in rectal surgery: proof of concept.

BACKGROUND: Coaching is maturing as a strategy for surgeons' continuous professional development in different types of surgery. Laparoscopic total mesorectal excision (LAP TME) is one of the recognized difficult procedures in colorectal surgery. Aim of this trial is to introduce the surgical coaching as a tool for a continuous technical education of LAP TME for cancer in a consultant surgeon carrier. METHODS: Twelve Italian colorectal surgeons were enrolled as trainees in the AIMS Academy rectal cancer surgical coaching project and attended a face-to-face 90-min surgical coaching on a pre-edited 45-min-long video of a laparoscopic proctectomy according to pre-determined guidelines. At the end of the coaching, all mentors were asked to fill a questionnaire evaluating the trainee's skills. All trainees had to fill a post-coaching questionnaire addressing the appropriateness of the coaching with respect to their actual level. RESULTS: Trainees were more confident in performing the extra-pelvic part of the surgical procedures compared to the intra-pelvic dissection. The most challenging steps according to the trainees were the seminal vesicles identification and the pelvic floor dissection. Mentors found the trainees quite confident in the approach to the vascular structures, lymphadenectomy, stapler utilization and bleeding control. The sharpness and the efficacy of the dissection, the dissection of the surgical planes and the anastomosis fashioning were reported at a lower level of confidence. The higher grade of satisfaction reported by the trainee came from the attention that the mentors demonstrated towards them, from the availability of the mentors to take into consideration the surgical issues raised and from the willingness to apply the suggestions received during their next proctectomies. CONCLUSIONS: The surgical coaching applied to LAP TME should be considered as an innovative tool for continuous professional development.

Long-term outcomes of transmesenteric portal vein recanalization for the treatment of chronic portal vein thrombosis after pediatric liver transplantation.

Portal vein thrombosis (PVT) may occur at any time following liver transplantation. We describe our experience with portal vein recanalization in cases of thrombosis after liver transplantation. Twenty-eight children (5%) out of 566 liver transplant recipients underwent portal vein recanalization using a transmesenteric approach. All children received left hepatic segments, developed PVT, and had symptoms or signs of portal hypertension. Portal vein recanalization was performed via the transmesenteric route in all cases. Twenty-two (78.6%) patients underwent successful recanalization and stent placement. They received oral anticoagulants after the procedure, and clinical symptoms subsided. Symptoms recurred due to portal vein restenosis/thrombosis in seven patients. On an intention-to-treat basis, the success rate of the proposed treatment was 60.7%. Only 17 out of 28 children with posttransplant chronic PVT retained stent patency (primary + assisted) at the end of the study period. In cases of portal vein obstruction, the transmesenteric approach via minilaparotomy is technically feasible with good clinical and hemodynamic results. It is an alternative procedure to reestablish the portal flow to the liver graft that can be performed in selected cases and a therapeutic addition to other treatment strategies currently used to treat chronic PVT.

A biocompatibility study of new nanofibrous scaffolds for nervous system regeneration.

The development of therapeutic approaches for spinal cord injury (SCI) is still a challenging goal to achieve. The pathophysiological features of chronic SCI are glial scar and cavity formation: an effective therapy will require contribution of different disciplines such as materials science, cell biology, drug delivery and nanotechnology. One of the biggest challenges in SCI regeneration is to create an artificial scaffold that could mimic the extracellular matrix (ECM) and support nervous system regeneration. Electrospun constructs and hydrogels based on self-assembling peptides (SAPs) have been recently preferred. In this work SAPs and polymers were assembled by using a coaxial electrospinning setup. We tested the biocompatibility of two types of coaxially electrospun microchannels: the first one made by a core of poly(ε-caprolactone) and poly(d,l-lactide-co-glycolide) (PCL-PLGA) and a shell of an emulsion of PCL-PLGA and a functionalized self-assembling peptide Ac-FAQ and the second one made by a core of Ac-FAQ and a shell of PCL-PLGA. Moreover, we tested an annealed scaffold by PCL-PLGA microchannel heat-treatment. The properties of coaxial scaffolds were analyzed using scanning electron microscopy (SEM), Fourier transform spectroscopy (FTIR), contact angle measurements and differential scanning calorimetry (DSC). In vitro cytotoxicity was assessed via viability and differentiation assays with neural stem cells (NSCs); whereas in vivo inflammatory response was evaluated following scaffold implantation in rodent spinal cords. Emulsification of the outer shell turned out to be the best choice in terms of cell viability and tissue response: thus suggesting the potential of using functionalized SAPs in coaxial electrospinning for applications in regenerative medicine.

Successful domino liver transplantation in maple syrup urine disease using a related living donor

Maple syrup urine disease (MSUD) is an autosomal recessive disease associated with high levels of branched-chain amino acids. Children with MSUD can present severe neurological damage, but liver transplantation (LT) allows the patient to resume a normal diet and avoid further neurological damage. The use of living related donors has been controversial because parents are obligatory heterozygotes. We report a case of a 2-year-old child with MSUD who underwent a living donor LT. The donor was the patient's mother, and his liver was then used as a domino graft. The postoperative course was uneventful in all three subjects. DNA analysis performed after the transplantation (sequencing of the coding regions of BCKDHA, BCKDHB, and DBT genes) showed that the MSUD patient was heterozygous for a pathogenic mutation in the BCKDHB gene. This mutation was not found in his mother, who is an obligatory carrier for MSUD according to the family history and, as expected, presented both normal clinical phenotype and levels of branched-chain amino acids. In conclusion, our data suggest that the use of a related donor in LT for MSUD was effective, and the liver of the MSUD patient was successfully used in domino transplantation. Routine donor genotyping may not be feasible, because the test is not widely available, and, most importantly, the disease is associated with both the presence of allelic and locus heterogeneity. Further studies with this population of patients are required to expand the use of related donors in MSUD.

Laparoscopic repair for recurrent incisional hernias: a single institute experience of 10 years.

PURPOSE: The treatment of recurrent incisional hernias (RIH) has been associated with unsatisfactory postoperative (PO) morbidity and high failure rates. The aim of this study is to retrospectively investigate our single-center experience of laparoscopic repair (LR) for RIH. METHODS: The case records of 69 patients with RIH who underwent LR in our institution between January 2002 and November 2011 were reviewed. The operative technique has been standardized and provides onlay placement of an ePTFE mesh fixed with titanium tacks. Patients' demographic data and comorbidities, intraoperative course, PO complications and recurrences at follow-up were systematically collected and analyzed. The influence of defect's size and obesity variables on clinical outcomes was also investigated. RESULTS: The mean operative time was 147.6 ± 71.2 min and mean hospital stay was 5.8 ± 1.8 days. No conversion occurred while five intraoperative complications (7.2 %) were recorded: three bowel injuries treated by laparoscopic sutures, one omentum bleeding and one epigastric vessel lesion. PO mortality was null, while overall morbidity was 13 % (9 patients) with a prevalence of seroma lasting over 8 weeks in six patients (8.7 %). Along a mean follow-up of 41 months (range 6-119), recurrence rate was 5.7 % (4 patients). Univariate analysis for width of defects and BMI showed no significant influence on patients' outcomes. CONCLUSIONS: Surgical treatment for RIH remains controversial because of lack in literature of specific studies on this topic. Morbid obesity and large defects have been often associated with technical difficulties and worse results. Our 10 years' experience with LR provided satisfactory results in terms of PO morbidity and recurrence rate, despite any kind of patient selection.

Temporary percutaneous ileostomy versus conventional loop ileostomy in mechanical extraperitoneal colorectal anastomosis: a retrospective study.

AIM: Loop ileostomy is a suitable procedure for transitory faecal diversion after low colorectal anastomosis, but it causes relevant morbidities (discomfort, peristomal infections, dehydration) and requires a second operation to be closed. We already described an alternative technique of temporary percutaneous ileostomy (TPI) that can be removed without surgery. METHOD: The data of 143 consecutive patients, undergoing elective laparoscopic anterior resection of the rectum for adenocarcinoma and low mechanical colorectal anastomosis, 68 with conventional loop ileostomy (CLI) and 75 with TPI, were analyzed. RESULTS: Neither intra-operative complications nor deaths occurred during the follow-up period. Clinical anastomotic leakage occurred in 4 patients with CLI and in 1 with TPI (p = 0.191). The median time required for the emission of gases and faeces through the stoma was respectively 1 and 2.5 days in the CLI group, and 1 and 2 days in the TPI group (p = 0.259 and p = 0.126). The median post-operative stay was 8 days in the CLI group and 11 days in the TPI group (p < 0.001). PTIs were removed on the median of 9 days after surgery without major complications, whereas the CLIs were re-canalized in 79.4% of patients on an average of 106 days, with 2 major complications. CONCLUSION: The temporary percutaneous ileostomy seems to be a valid alternative to conventional ileostomy, ensuring optimal faecal diversion and less patient discomfort. It can be easily removed without surgery, allowing patients a better outcome.

Outcomes and survival after laparoscopic gastrectomy for adenocarcinoma. Analysis on 65 patients operated on by conventional or robot-assisted minimal access procedures.

AIMS: Despite laparoscopic surgery for gastric cancer has gained worldwide acceptance, long term results and survival are seldom reported. This study was designed to assess long term outcomes after laparoscopic gastrectomy with D2 dissection. The short term results of conventional and robot-assisted minimally invasive procedures were also examined. PATIENTS AND METHODS: The charts of 65 patients who underwent laparoscopic surgery for non-metastatic adenocarcinoma were reviewed retrospectively. This series included 35 patients with early gastric cancer (EGC) and 30 with advanced gastric cancer (AGC). A 4/5 laparoscopic subtotal gastrectomy (LSG) with D2 nodal clearance was the procedure of choice for distal cancers. Laparoscopic total gastrectomy (LTG) with modified D1 lymphadenectomy was performed for mid-proximal EGC. RESULTS: Sixty gastrectomies were carried out laparoscopically, 56 LSG and 4 LTG. Conversion to laparotomy was required in 5 patients with distal cancer. No intraoperative complication was registered. Morbidity included 2 duodenal leaks that healed conservatively. Two postoperative deaths were registered. An average number 31.3+/-8.8 lymph nodes were collected. The mean hospital stay was 10 days (range 7-24). The mean follow up was 30 months (range 2-86) and the cumulative overall 5 year survival rate was 78%. Survival at 5 years for EGC was 94% and survival at 4 years for AGC was 53% (57% for non-converted patients). CONCLUSIONS: Laparoscopic gastrectomy for cancer represents a valid alternative to open surgery with minimal morbidity and acceptable long term survival. Considering the risk of preoperative under diagnoses a D2 lymphadenectomy is suggested also for EGC. This study validated the effectiveness of minimally invasive technique in the management of gastric cancer.

Laparoscopic resection for rectal adenocarcinoma.

AIMS: Laparoscopic surgery for rectal cancer is still under discussion, but there is evidence that minimal access surgery can be feasible and safe also in this field. The aim of this study was to confirm that laparoscopic resection for rectal cancer can afford good results in terms of recurrence rate and survival. PATIENTS AND METHODS: Since June 1998 through December 2007 as many as 252 patients underwent laparoscopic resection for rectal cancer. Laparoscopic anterior resection (LAR) was performed in 209 and laparoscopic abdominoperineal resection (LAPR) in 43. Neoadjuvant radiochemotherapy (nCRT) was administered in 48 patients with mid-low rectal cancer stage II and III with evidence of nodal involvement in preoperative work up. RESULTS: Patients who received nCRT showed a significant longer duration of surgery compared to patients who did not (p=0.004). Conversion to laparotomy was needed in 24 cases, (21 LAR and three LAPR) but no patient receiving nCRT needed conversion. Postoperative surgical complications occurred in 38 patients, 20 of which were represented by anastomotic leak after LAR. Six patients died postoperatively, in half the cases for surgery related causes. Downstaging after nCRT was seen in 40 patients, and complete histological response was observed in six cases. The mean number of lymph nodes harvested was 12, also in patients receiving nCRT. The mean follow-up was 48+/-33 months (range 0.1-120.4), and 10 patients experienced local recurrence. Cumulative 5 year survival was 73.7%. CONCLUSION: Laparoscopic resection for rectal cancer is feasible and safe, with morbidity and long-term results quite acceptable also in patients receiving neoadjuvant treatment.

Laparoscopic management of incisional hernias > or = 15 cm in diameter.

BACKGROUND: Despite good results in terms of safety and minimal recurrence ensured by laparoscopy in the management of incisional hernias, the use of minimally invasive techniques for large incisional wall defects is still controversial. METHODS: Between 2002 and 2008 as many as 36 patients with abdominal wall defects > or = 15 cm were managed laparoscopically in our institution. The wall defects were > or = 20 cm in eight cases. The diameter of parietal defects was measured from within the peritoneal cavity. None had loss of domain. Body mass index (BMI) for 18 patients was > or = 30 kg/m(2). RESULTS: The mean duration of operations was 195 +/- 28 min (range 75-540). One patient needed conversion for ileal injury and massive adhesions. Post-operative complications occurred in nine patients; there were six surgical complications. Morbidity in obese and non-obese patients was not statistically different (p > 0.05). There was no postoperative death. Mean hospital stay was 4.97 +/- 3.4 days (range 2-18). Mean follow up was 28 months (range 2-68) and only one hernia recurrence was observed. CONCLUSIONS: Minimum-access procedures can provide good results in the repair of giant incisional hernia. Obesity is not a contraindication to laparoscopic repair. Further studies are expected to confirm our promising results.

Haptoglobin from psoriatic patients exhibits decreased activity in binding haemoglobin and inhibiting lecithin-cholesterol acyltransferase activity.

OBJECTIVE: The aim of this work was to assess whether psoriasis is associated with phenotype prevalence and altered activity of haptoglobin (Hpt). BACKGROUND: Hpt is a plasma acute-phase glycoprotein, displaying in humans three phenotypes. Phenotype prevalence or structure modification of Hpt was associated with several diseases. The Hpt main function is to bind and carry to the liver free haemoglobin for degradation and iron recycling. Hpt was recently found able to bind the apolipoprotein A-I (ApoA-I), thus impairing its stimulation on the activity of the enzyme lecithin-cholesterol acyl-transferase (LCAT). STUDY DESIGN: Hpt was isolated from patients with psoriasis vulgaris, and its activity in haemoglobin or ApoA-I binding and LCAT inhibition was compared with that of normal protein. METHODS: Two affinity chromatography steps, the first using resin-coupled haemoglobin and the second anti-Hpt antibodies, were used to purify Hpt. The protein phenotype was assessed by electrophoresis. Binding experiments were performed by Enzyme-linked immunosorbent assay with stationary haemoglobin or ApoA-I, Hpt in solution and anti-Hpt antibodies for detection of bound Hpt. Standard LCAT assays were carried out in the presence of Hpt purified from patients or healthy subjects. RESULTS: Phenotype prevalence of Hpt in psoriasis was not found. After affinity chromatography by haemoglobin, albumin and ApoA-I were routinely found heavily contaminating only Hpt from normal subjects. Isolated Hpt from patients had lower activity than normal protein in both haemoglobin binding and LCAT inhibition. CONCLUSIONS: In psoriasis, Hpt displays some structure modification(s), which might be associated with the protein function in the disease.

Robot-assisted laparoscopic gastrectomy with D2 dissection for adenocarcinoma: initial experience with 17 patients.

Robot-assisted gastrectomy has been practised so far in very few centres in the world. The aims of this study were to assess the feasibility of robot-assisted gastrectomy for adenocarcinoma with D2 lymph nodal dissection and to analyze our preliminary results. Between January 2006 and August 2008, as many as 17 patients (11 females, 6 males) underwent laparoscopic robot-assisted surgery for non-metastatic adenocarcinoma of the stomach by a 3-armed da Vinci(®) Robotic Surgical System. The mean age of patients was 65.9 years. This series included eight patients with early gastric cancer (EGC) and nine with advanced gastric cancer (AGC). A 4/5 laparoscopic subtotal gastrectomy (LSG) with D2 nodal clearance was the procedure of choice for 16 distal cancers. Laparoscopic total gastrectomy (LTG) with D2 lymphadenectomy was performed for one AGC of the middle third of the stomach. No intraoperative complication was registered. Conversion to laparotomy was required in two patients with distal cancer. The mean operating time (excluding converted patients) was 352 min (348 for LSG). Morbidity consisted in one pancreatic leak that healed conservatively. One death occurred postoperatively for haemorragic stroke. On average, 25.5 ± 4 lymph nodes were collected (range 10-40). The resection margin was 6.4 ± 0.6 cm (range 4.2-8), and the margin was tumour free in all the specimens. The mean hospital stay of totally laparoscopic subtotal gastrectomy was 10 ± 1.2 days (range 8-13). The mean follow-up was 14 months (range 1-29) and three patients with AGC showed recurrence after LSG and died of disease. Robotics in gastrectomy for cancer is a feasible and safe procedure, yielding adequate D2 nodal clearance with respect of oncologic principles. Robotic techniques can represent a remarkable tool to improve laparoscopic surgeon's ability and precision in small surgical fields, i.e. during D2 dissection. This study demonstrated the feasibility of robot-assisted gastrectomy for cancer although further studies are required to validate our preliminary results, especially as far as patients' benefits are concerned.

Stapled hemorrhoidopexy: day surgery or one day surgery?

Hemorrhoidal disease is one of the most common anorectal disorders, from 10% to 20% of all patients admitted at a clinical investigation need to undergo surgery, stapled haemorrhoidopexy is gaining wide acceptance as an interesting, safe and less painful technique, but hemorrhage is one of the most serious early complications and is a severe complication in day surgery. In our day surgery proctology, surgical procedures represent about 32%. Of these, 24% are for hemorrhoidal disease, we present our protocol and experience for early and safe discharge, 6h after stapled hemorrhoidopexy surgery.

Total and subtotal laparoscopic gastrectomy for adenocarcinoma.

BACKGROUND: Laparoscopic gastrectomies are currently performed in many centers, but compliance with oncologic requirements still represents a subject open to debate. The aim of this work was to compare the short-term and oncologic outcomes after laparoscopic and open surgery in gastric adenocarcinoma. METHODS: From June 2000 through June 2005, 147 patients in our institution underwent gastrectomy by open or mininvasive approach for adenocarcinoma. The laparoscopy group included 48 patients, 29 with early gastric cancer (EGC) and 19 with antral advanced gastric cancer (AGC). The short-term results and oncologic data were compared to those obtained in 99 patients who underwent open surgery. Survival in the laparoscopy group was analyzed. RESULTS: In the laparoscopy group no intraoperative complications were observed, and conversion was needed in only one patient with a large advanced tumor. Overall, 32 lymph nodes were collected by D2 dissection, 30 for EGC, 34 for advanced cancers. The resection margin was 6.7 cm (range: 4-8 cm). The mean operating time was 240 min (range: 150-360 min), with a blood loss of 150 ml on average (range: 70-250 ml). Morbidity included two duodenal leaks that healed without reoperation; after enclosing or reinforcing the staple line, no further leaking was noted. There was one death from massive bleeding in a cirrhotic patient. Ambulation and oral feeding started significantly earlier than in open surgery. The mean hospital stay was 10 days (range: 7-24 days), significantly shorter than the stay of 18 days after open surgery (p < 0.05). All patients treated laparoscopically were alive without recurrence at the end of this study. CONCLUSIONS: Short-term results with laparoscopic gastrectomy were better than with open surgery in this study. Oncologic radicality was a major concern, but in the authors' experience the extent of lymphadenectomy was the same as in open surgery. This study suggests that laparoscopic gastrectomy in malignancies is a reliable tool and oncologic requirements can be warranted.
