To evaluate the effects of rehabilitation (physical and cognitive) treatments on the diagnosis severity and Disability Rating Scale (DRS) scores, adjusted for a number of potential confounders measured at baseline, in a large cohort of patients with disorders of consciousness across time.An observational, longitudinal (2 evaluations), multicenter project was made in 90 Italian centers.Patients (N=364) with a diagnosis of disorders of consciousness.Primary outcome was the severity of diagnosis, expressed on an ordinal scale (OtherMCSVSdeath). In the Other group were included patients who emerged from an MCS and recovered consciousness. The secondary outcome was the DRS score (range of 0-30 with 30 being the worst value). The DRS is a tool used to define the level of residual disability, commonly used to classify the level of functional impairment in patients with acquired brain injury. Both outcomes were measured for each wave.A total of 364 subjects having a complete set of demographic, clinical, and pharmacologic data were included in the propensity score (PS) analysis. Results showed that the rehabilitation treatments (physical and cognitive) reduced the clinical worsening over time in both severity diagnosis and DRS (around 6.5 points) in patients with disorders of consciousness across different propensity score strategies (ie, PS matching, PS adjustment, and PS-weighted procedures). In addition, cognitive protocols seem to be limited to patients with a median value of DRS=23.Our propensity score analysis suggests that rehabilitation treatment protocols seem effective and should be applied to a broader spectrum of patients with disorders of consciousness.

SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) has been identified in China as responsible for viral pneumonia, now called COVID-19 (Coronavirus Disease 2019). Patients infected can develop common symptoms like cough and sore throat, and, in severe cases, acute respiratory syndrome and even death. To optimize the available resources, it is necessary to identify in advance the subjects that will develop a more serious illness, therefore requiring intensive care.The neutrophil / lymphocyte ratio (NLR) parameter, resulting from the blood count, could be a significant marker for the diagnosis and management of risk stratification.A retrospective, single-center case-control observational study was conducted. The differential cell count of leukocytes, the NLR and the clinical course of patients hospitalized in intensive care with COVID-19 were analyzed, comparing them with other patients (COVID-19 and non-COVID-19) and healthy individuals selected among workers of the Teaching Hospital Policlinico Umberto I in Rome.370 patients (145 cases and 225 controls) were included in the case-control study, 211 males (57%) and 159 females (43%). The average age of the population was 63 years (SD 16.35). In the group of cases, out of 145 patients, 57 deaths and 88 survivors were recorded, with a lethality rate of 39.3%. The group of cases has an NLR of 7.83 (SD = 8.07), a much higher value than the control group where an NLR of 2.58 was recorded (SD = 1.93) (p0.001). The Neutrophils / Lymphocytes ratio may prove to be a diagnostic factor for COVID-19, an NLR3.68 revealed an OR 10.84 (95% CI = 6.47 - 18.13) (p0.005).The value of NLR considered together with the age variable allows a risk stratification and allows the development of diagnostic and treatment protocols for patients affected by COVID-19. A high neutrophil to lymphocyte ratio suggests worse survival. Risk stratification and management help alleviate the shortage of medical resources and reduce the mortality of critically ill patients.

Objective To investigate the clinical manifestations at diagnosis and during follow-up in patients with 22q11.2 deletion syndrome to better define the natural history of the disease. Study design A retrospective and prospective multicenter study was conducted with 228 patients in the context of the Italian Network for Primary Immunodeficiencies. Clinical diagnosis was confirmed by cytogenetic or molecular analysis. Results The cohort consisted of 112 males and 116 females; median age at diagnosis was 4 months (range 0 to 36 years 10 months). The diagnosis was made before 2 years of age in 71% of patients, predominantly related to the presence of heart anomalies and neonatal hypocalcemia. In patients diagnosed after 2 years of age, clinical features such as speech and language impairment, developmental delay, minor cardiac defects, recurrent infections, and facial features were the main elements leading to diagnosis. During follow-up (available for 172 patients), the frequency of autoimmune manifestations ( P = .015) and speech disorders ( P = .002) increased. After a median follow-up of 43 months, the survival probability was 0.92 at 15 years from diagnosis. Conclusions Our data show a delay in the diagnosis of 22q11.2 deletion syndrome with noncardiac symptoms. This study provides guidelines for pediatricians and specialists for early identification of cases that can be confirmed by genetic testing, which would permit the provision of appropriate clinical management.

The pharmacokinetics of the extemporaneous combination of low doses of ketamine and propofol, known as 'ketofol', frequently used for emergency procedures in humans to achieve safe sedation and analgesia was studied in cats. The study was performed to assess propofol, ketamine and norketamine kinetics in six female cats that received ketamine and propofol (1:1 ratio) as a loading dose (2 mg/kg each, IV) followed by a continuous infusion (10 mg/kg/h each, IV, 25 min of length). Blood samples were collected during the infusion period and up to 24 h afterwards. Drug quantification was achieved by HPLC analysis using UV-visible detection for ketamine and fluorimetric detection for propofol. The pharmacokinetic parameters were deduced by a two-compartment bolus plus infusion model for propofol and ketamine and a monocompartmental model for norketamine. Additional data were derived by a noncompartmental analysis. Propofol and ketamine were quantifiable in most animals until 24 and 8 h after the end of infusion, respectively. Propofol showed a long elimination half-life (t(1/2λ2) 7.55 ± 9.86 h), whereas ketamine was characterized by shorter half-life (t(1/2λ2) 4 ± 3.4 h) owing to its rapid biotransformation into norketamine. The clinical significance of propofol's long elimination half-life and low clearance is negligible when the drug is administered as short-term and low-dosage infusion. The concurrent administration of ketamine and propofol in cats did not produce adverse effects although it was not possible to exclude interference in the metabolism.

Introduction On February 20, 2020, a severe case of pneumonia due to SARS-CoV-2 was diagnosed in northern Italy (Lombardy). Some studies have identified obesity as a risk factor for severe disease in patients with COVID-19. The purpose of this study was to investigate the incidence of SARS-CoV-2 infection and its severity in patients who have undergone bariatric surgery. Material and Methods During the lockdown period (until May 2020), we contacted operated patients by phone and social networks (e.g., Facebook) to maintain constant contact with them; in addition, we gave the patients a dedicated phone number at which to call us for emergencies. We produced telemedicine and educational videos for obese and bariatric patients, and we submitted a questionnaire to patients who had undergone bariatric surgery in the past. Results A total of 2145 patients (313 male; 1832 female) replied to the questionnaire. Mean presurgical BMI: 44.5 ± 6.8 kg/m2. Mean age: 44.0 ± 10.0 year. Mean BMI after surgery: 29.3 ± 5.5 kg/m2 (p

Purpose: Bariatric surgery (BS) is considered the most efficient treatment for severe obesity. International guidelines recommend multidisciplinary approach to BS (general practitioners, endocrinologists, surgeons, psychologists, or psychiatrists), and access to BS should be the final part of a protocol of treatment of obesity. However, there are indications that general practitioners (GPs) are not fully aware of the possible benefits of BS, that specialty physicians are reluctant to refer their patients to surgeons, and that patients with obesity choose self-management of their own obesity, including internet-based choices. There are no data on the pathways chosen by physicians and patients to undergo BS in the real world in Italy. Methods: An exploratory exam was performed for 6 months in three pilot regions (Lombardy, Lazio, Campania) in twenty-three tertiary centers for the treatment of morbid obesity, to describe the real pathways to BS in Italy. Results: Charts of 2686 patients (788 men and 1895 women, 75.5% in the age range 30–59 years) were evaluated by physicians and surgeons of the participating centers. A chronic condition of obesity was evident for the majority of patients, as indicated by duration of obesity, by presence of several associated medical problems, and by frequency of previous dietary attempts to weight loss. The vast majority (75.8%) patients were self-presenting or referred by bariatric surgeons, 24.2% patients referred by GPs and other specialists. Self-presenting patients were younger, more educated, more professional, and more mobile than patients referred by other physicians. Patients above the age of 40 years or with a duration of obesity greater than 10 years had a higher prevalence of all associated medical problems. Conclusions: The majority of patients referred to a tertiary center for the treatment of morbid obesity have a valid indication for BS. Most patients self-refer to the centers, with a minority referred by a GP or by specialists. Self-presenting patients are younger, more educated, more professional, and more mobile than patients referred by other physicians. Older patients and with a longer duration of obesity are probably representative of the conservative approach to BS, often regarded as the last resort in an endless story.

Background and Aims: Although laparoscopic one anastomosis gastric bypass (LOAGB) is a promising bariatric procedure, a large number of surgeons have strong objections mainly because of risk of bile reflux, marginal ulceration, malnutrition, and long-term risk of gastric and esophageal cancer. Lateral enteroenterostomy placed distally to a gastrojejunal anastomosis shows efficacy in preventing bile reflux after gastric resection and gastrojejunal anastomosis, but at present its efficacy in a bariatric surgery context has not been evaluated. Patients and Methods: From January 2013 to December 2018, 100 patients have been admitted to our department to be treated by performing LOAGB. Patients have been divided into two groups on the basis of the indications to this surgical procedure; Group A: presence of de novo gastroesophageal reflux disease (GERD) or severe esophagitis after laparoscopic sleeve gastrectomy, with or without weight regain; Group B: LOAGB as primary procedure. Another group of 30 patients (Group C) underwent LOAGB with Braun anastomosis as primary bariatric surgical procedure for morbid obesity. We have conducted a retrospective analysis of the surgical outcomes in terms of perioperative mortality, short-, mid-, and long-term postoperative complications and weight loss. Results: Group A: 50 patients; incidence of postoperative GERD, esophagitis, or esophageal ulcers was 26% (13 cases). All these patients have been successfully treated by performing Braun anastomosis. Group B: 20 patients; incidence of de novo reflux was 25% (5 cases); Braun anastomosis was performed with complete resolution of signs and symptoms in all cases. Group C: 30 patients; no cases of de novo reflux, esophagitis, or anastomotic ulcers occurred. Conclusion: Braun anastomosis seems to be a useful surgical tool to prevent the onset of de novo reflux, esophagitis, and anastomotic ulcers.

Purpose: Aim of this study was to analyse feasibility, safety and effectiveness of laparoscopic transperitoneal hernia repair (TAPP) approach to inguinal hernias in the emergency setting, with a longer follow-up than the studies present in literature. Methods: We retrospectively analysed all patients who underwent emergency TAPP hernia repair in San Marco Hospital (Zingonia, Italy), from September 2010 to June 2020. A prospectively collected database of 685 consecutive TAPP hernia repair was reviewed. Feasibility and safety were evaluated through operative time, conversion rate, perioperative mortality, morbidity and prosthesis infection rate. Effectiveness was assessed by recurrence and complication rate, acute (during admission) and chronic (during follow-up) pain by Visual Analogic Scale (VAS), and recovery to normal activity in a long-term follow-up (mean period 1718days). Results: The final study group included 47 patients. The mean age was 59.6years (range 22–89), 29 patients were male and 18 were female. The mean operation time was 64min. Two cases were converted to open approach (4%). In four cases bowel resection became necessary (8.5%). Appendicectomy and omentectomy occurred once and twice, respectively (2% and 4%), and orchiectomy was required in two patients (4%). Seroma was the only postoperative complication that we registered in four patients.During a mean follow-up period of 1718days, there was no recurrence of the hernia or other complications. Five patients referred mild occasional groin pain (VAS < 3), with quick relief without taking any pain killers. Conclusion: TAPP approach is a safe, feasible and effective therapeutic option for groin hernias in emergency setting. No recurrence or severe complications were reported in over 4years of follow-up.

Background: Colorectal cancer, one of the most common tumor- and cancer-related deaths worldwide, requires a multidisciplinary management including neoadjuvant chemoradiotherapy and surgery. Laparoscopic surgery for rectal cancer is gaining popularity due to its safety profile and good oncological results, if performed by experienced surgeons in specialized centers. This study describes our 10 years experience in minimally invasive rectal cancer surgery. Methods: We have retrospectively evaluated a series of 140 patients treated with laparoscopic approach for rectal malignant and benign diseases. Results: A total of 134 patients (95.7%) underwent anterior rectal resection, in the remaining 6 cases (4.3%) abdominoperineal amputation was performed. All but 13 cases have been treated with laparoscopic approach, with conversion rate of 5.7%. Postoperative morbidity rate was 8.6% (2 cases of peritoneal bleeding and 10 cases of anastomotic fistulae; in 2 cases, fistula occurred in patients previously treated with chemoradiation). Conclusions: Conventional laparoscopy can provide adequate oncological outcomes even in patients with advanced rectal cancer, with advantages in terms of postoperative hospital stay, recovery time, acceptable operative time, and low complication and conversion rates.

Laparoscopic Sleeve Gastrectomy (LSG) is one of the most performed surgical procedures in bariatric surgery. Staple line leak and bleeding are by far the two most feared complications after LSG. In this study, we retrospectively compared the efficacy of Fibrin Glue in preventing staple line leak and bleeding. From September 2019 to January 2020, 450 obese patients underwent elective LSG and were placed into groups with Fibrin Glue reinforcement (Group A) or without Fibrin Glue reinforcement (Group B). Primary endpoints were postoperative staple line leak and bleeding; while, secondary endpoints were reintervention rate, total operative time and mortality. Mean Body Mass Index (BMI) was 45.4 ± 7.9kg/m2 (range: 35.1–81.8). Mean age was 43.3 ± 11.8years (range: 18–65). No intraoperative complications or conversion to laparotomy were reported. Mean operative time was comparable between the groups (48 ± 18min in Group A vs 48 ± 14min in Group B; p > 0.05). No decrease in overall postoperative complications was found in Group A (5.1% vs 7.0%; p > 0.05), but after stratification according to Clavien–Dindo classification, we found a higher rate of Grade II (0.0% vs 1.6%; p < 0.05) and Grade IIIb (0.0% vs 1%; p < 0.05) complications in group B. Our study showed that Fibrin Glue as a reinforcement method during LSG is a reliable tool, without affecting the operative time of surgery and mortality. A significant reduction in complications (Clavien–Dindo grade II and grade IIIb) was observed in patients undergoing LSG with Fibrin Glue.

Introduction: The debate is still open about laparoscopic treatment of gastric cancer. The aim of this retrospective study is to analyze our short-, medium-, and long-term surgical and oncological results in laparoscopic treatment of gastric cancer with D2 lymphadenectomy and omentum preservation. Materials and Methods: From January 2010 to June 2018, after >150 surgical procedures for gastric cancer performed by minimally invasive approach, we performed 100 laparoscopic subtotal gastrectomies and 38 total gastrectomies, both for early gastric cancer (EGC) and advanced gastric cancer (AGC). We always made a D2 lymphadenectomy or higher. As often as possible, we performed omentum-preserving technique. Primary outcomes analyzed included incidence of medical and surgical complications. Secondary outcomes analyzed were survival probability and incidence of relapse. Every patient read and signed informed consent before surgery. Results: Mean operative time: 2.4 ± 0.7 hours (range 1.2-4.7 hours). Rate of conversions: 14.5% (20/138); intraoperative complications: 1.4% (2/138) and positive resection margins: 6.5% (9/138). Overall incidence of duodenal fistula: 3.6% (5/138). Rate of reoperation was 7.3% (10/138). Postoperative complications according to Clavien-Dindo classification: I 3.6% (5/138); II 13.0% (18/138); III 5.8% (8/138); III B 0.7% (1/138); V 1.4% (2/138). Overall survival with 60 months follow-up was 58%. Overall 60 months incidence of relapse was 44%. Patients with omentum preservation had a lower incidence of relapse than patients with omentectomy (40% versus 57% P =.002). Conclusions: Laparoscopic treatment of gastric cancer with D2 lymphadenectomy and omentum preservation is safe and feasible, both for EGC and for AGC. Although this study has limitations, omentum-preserving technique was associated with a statistically lower recurrence rate.

Background Gastroesophageal reflux disease (GERD), including erosive esophagitis, is highly prevalent in the obese population. Laparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed bariatric procedures. The relationship between LSG and GERD has gained increasing attention. This retrospective study aimed to assess the effectiveness of combined LSG and modified Rossetti antireflux fundoplication for the treatment of GERD on morbidly obese patients after bariatric surgery. Objectives To assess the effectiveness, on morbid obese patients, of combined SG and Rossetti fundoplication for the treatment of GERD in obese patients. Setting Public Hospital, Italy. Methods From January 2015 to May 2018, 220 obese patients (167 female; 53 male) underwent LSG and modified Rossetti antireflux fundoplication procedure, performed by 4 different expert bariatric surgeons. Data have been collected in an Excel file and processed by XLStat to perform statistical analyses. We analyzed short-term complications and medium-term results with 24-month follow-up in terms of weight loss, remission of co-morbidities, and resolution of GERD. Results Mean BMI was 42.58 ± 5.93 kg/m2 (range, 31.70–63.16). Patients suffering from GERD before surgery were 137 of 220 (62.3%). No intraoperative complications or conversion were reported. Regular postoperative course was recorded in 90% of patients (198 of 220 patients). Gastric perforation has always occurred on the fundoplicated portion of the stomach. This perforation, which is different from the well-known post-LSG gastric fistula, may be because of incorrect gastric fundus manipulation. Rate of reoperation was 14 of 220 (6.4%). A good sense of repletion without episodes of vomiting, nausea, or dysphagia was reported in 95% of the analyzed patients. Of patients, 98.5% did not suffer from reflux symptoms and did not take proton pump inhibitors. A decrease in BMI and percent of total weight loss at follow-up were comparable with LSG. Endoscopic follow-up is still ongoing. Improvement in esophagitis was observed in 63 of 65 (96.92%) patients and all 4 patients shows improvement in Barrett’s esophagus. Conclusions LSG and modified Rossetti antireflux fundoplication procedure is a tolerated and feasible procedure in obese patients, with good postoperative weight loss results and improvement in GERD.

Background and Objectives: Literature demonstrates that colorectal cancer is nowadays one of the most common malignancies. Laparoscopy and robotic surgery are progressively gaining popularity in the treatment of colo-rectal tumors. Complete mesocolic excision and central vascular ligation have been widely adopted with encouraging results in terms of an improvement of overall sur-vival, but some studies in the literature seem to demon-strate a higher morbidity rate. Methods: We conducted a retrospective study from 01/ 01/2010 to 30/04/2019 on a series of 250 patients, 155 males (62%) and 95 females (38%) who underwent right colectomy with minimally invasive approach, complete mesocolic excision, central vascular ligation, and intracor-poreal anastomosis. Results: No perioperative mortality occurred. Postoperative morbidity rate was 6%, including 10 cases of anasto-motic leak (5%). Conversion rate was 2.5%. Mean hospital stay was 6 days (range, 4 –25 days). Mean operative time was 70 minutes (range, 50 –130 minutes). No cases of duodenal or pancreatic damages, no chronic pain or di-arrhea, and no severe alteration of bowel function were recorded. We observed only 3 cases of transient delayed gastric emptying. Conclusions: Laparoscopic right colectomy with complete mesocolic excision, central vascular ligation and intracorporeal anastomosis leads to encouraging oncolog-ical mid-and long-term outcomes with low complications rates.

Background and Objectives: The aim of this retrospective monocentric study was to evaluate results and recurrence rate with long-term follow-up after laparoscopic incisional/ventral hernia repair. Methods: This was a retrospective, single-center, obser-vational trial, collecting data from patients who underwent laparoscopic incisional/ventral abdominal hernia repair using the open intraperitoneal onlay mesh technique and a single mesh type. All patients signed an informed consent form before surgery. Results: A total of 1,029 patients were included. The median surgery time was 40 min (range 30–55) and the median length of hospital stay was 2 d (range 2–3). Intra-operative complications occurred in two of 1,029 patients (0.19%), whereas early postoperative surgical complications (within 30 d) occurred in 50 patients (4.86%). Postoperative complications according to Clavien-Dindo clas-sification were as follows: I, 3.30% (34 of 1,029); II, 0.97% (10 of 1,029); IIIB, 0.58% (six of 1,029); IV, 0.00% (none of 1,029); and V, 0.00% (none of 1,029). During follow-up, bulging mesh was diagnosed in 58 of 1,029 patients (5.6%), and hernia recurred in 40 of 1,029 patients (3.9%). A mesh overlap equal to or greater than 4 cm appeared to be a significant protective factor for hernia recurrence (P < .001); a mesh overlap equal or greater than 5 cm appeared to be a significant protective factor for bulging (P < .001), whereas the use of resorbable fixing devices was a significant risk factor for hernia recurrence (odds ratio, 111.53, P < .001, 95% confidence interval, 21.53– 577.67). Conclusion: This study demonstrates that laparoscopic repair of ventral/incisional abdominal wall hernias is a safe, effective, and reproducible procedure. Identified risk factors for recurrence are an overlap of less than 4 cm and the use of resorbable fixation means.

Background Celiac disease (CD) is an immune-mediated disorder characterized by an accumulation of immune cells in the duodenal mucosa as a consequence of both adaptive and innate immune responses to undigested gliadin peptides. Mast cells (MCs) are innate immune cells that are a major source of costimulatory signals and inflammatory mediators in the intestinal mucosa. Although MCs have previously been associated with CD, functional studies have never been performed. Objective We aimed at evaluating the role of MCs in the pathogenesis of CD. Methods Intestinal biopsy specimens of patients with CD were scored according to the Marsh classification and characterized for leukocyte infiltration and MC distribution. Moreover, MC reactivity to gliadin and its peptides was characterized by using in vitro assays. Results Infiltrating MCs were associated with the severity of mucosal damage, and their numbers were increased in patients with higher Marsh scores. MCs were found to directly respond to nonimmunodominant gliadin fragments by releasing proinflammatory mediators. Immunohistochemical characterization of infiltrating MCs and the effects of gliadin peptides on intestinal MCs indicated an increase in proinflammatory MC function in advanced stages of the disease. This was also associated with increased neutrophil accumulation, the prevalence of M1 macrophages, and the severity of tissue damage. Conclusion We provide a description of the progressive stages of CD, in which MCs are the hallmark of the inflammatory process. Thus the view of CD should be revised, and the contribution of MCs in the onset and progression of CD should be reconsidered in developing new therapeutic approaches.
