Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive and highly lethal malignancies. find more Existing therapeutic interventions have so far been unsuccessful in improving prognosis, and survival remains very poor. Oncolytic virotherapy represents a promising, yet not fully explored, alternative strategy for the treatment of PDAC. Oncolytic viruses (OVs) infect, replicate within and lyse tumor cells specifically and stimulate antitumor immune responses. Multiple challenges have hampered the efficacy of oncolytic virotherapy for PDAC, the most significant being the desmoplastic and immunosuppressive pancreatic tumor microenvironment (TME). The TME limits the access of therapeutic drugs and the infiltration of effector T cells and natural killer (NK) cells into the tumor mass. Additionally, cancer cells promote the secretion of immunosuppressive factors and develop mechanisms to evade the host immune system. Because of their oncolytic and immune-stimulating properties, OVs are the ideal candidates for counteracting the pancreatic immunosuppressive TME and for designing combination therapies that can be clinically exploited in clinical trials that seek to improve the prognosis of PDAC.
Academic hospitals must train future surgeons, but whether residents could negatively affect the outcomes of major procedures is a matter of concern. The aim of this study is to assess if pancreatic surgery is a safe teaching model.

Outcomes of 1230 major pancreatic resections performed at a high-volume pancreatic teaching hospital between 2015 and 2018 were compared according to the first surgeon type, attending vs resident.

Residents performed a selection of 132 (16%) pancreaticoduodenectomies (PD) and 46 (11%) distal pancreatectomies (DP). For PD, pancreatic fistula (25% vs 0, p<0.001), biliary fistula (7.1% vs 3.5%, p=0.04) and operative time (400 vs 390 min, p<0.001) were lower for residents but post-pancreatectomy hemorrhage was higher (20.5% vs 13% p=0.024). For DP, pancreatic fistula rate was lower for residents (31.7% vs 17.5% p=0.046). There was no difference in terms of lymph nodes retrieval both for PDs and DPs, while the R1 resections were more frequent among PDs performed by attending surgeons (31.5% vs 15.7%, p=0.023).

The active participation of residents does not negatively affect outcomes of major pancreatic resections in a high-volume center. By means of case selection and continuous tutoring, pancreatic surgery represents a safe and valid teaching model.

Repeat hepatectomy has been recognized as an effective treatment for hepatic malignancies, and a sheet type adhesion barrier, Seprafilm® has increasingly been used during hepatectomy to ease future relaparotomy. However, there is not yet sufficient evidence to support the safety of use of Seprafilm in liver surgery.

Data of 151 patients who had undergone open hepatectomy were retrospectively reviewed and the incidence of major abdominal morbidity was compared between patients in whom Seprafilm had and had not been used.

Seprafilm was used in 108 patients (Seprafilm group) and no adhesion barrier was used in 43 patients (comparison group). There was no significant difference in the rate of major abdominal morbidities between the two groups (Seprafilm vs. comparison 10% vs. 16%, P=0.403). Although the Seprafilm group showed a tendency toward increased incidence of bile leakage (7% vs. 2%), and placement of Seprafilm on the hepatoduodenal ligament or on the visceral surface of the liver seemed to be associated with an increased incidence of major morbidity, multivariate analysis showed no significant correlation between the use of Seprafilm and postoperative major abdominal morbidity.

Use of Seprafilm may not increase the risk of major abdominal morbidity in liver surgery.

Airway abnormalities complicate the perioperative course of patients with congenital heart disease (CHD), leading to significant morbidity and mortality. The literature describing airway abnormalities in those patients is scarce. This study aimed to determine the incidence of airway abnormalities in CHD patients and identify associated factors, genetic syndromes, and cardiac diagnoses.

Retrospective study conducted after institutional review board approval.

Tertiary children's hospital.

Patients presenting for cardiac diagnostic, interventional, or surgical procedures from 2012 to 2018. A total of 9,495 encounters were reviewed.

age >18 years. Methods/Interventions Age, weight, sex, intubation technique, number of intubation attempts, and difficult intubation (DI) were recorded. Using the International Classification of Diseases, Ninth and Tenth Revisions codes, genetic syndromes, acquired and congenital airway abnormalities, and cardiac diagnoses were identified. Multivariate generalized estimatay abnormality should be considered in premature CHD patients, weight less then 10 kg, and in those with specific cardiac lesions and a concomitant genetic syndrome. Preoperative identification of patients at high risk of airway abnormalities is useful in planning their perioperative airway management.The pulmonary artery catheter (PAC) has revolutionized bedside assessment of preload, afterload, and contractility using measured pulmonary capillary wedge pressure, calculated systemic vascular resistance, and estimated cardiac output. It is placed percutaneously by a flow-directed balloon-tipped technique through the venous system and the right heart to the pulmonary artery. Interest in the hemodynamic variables obtained from PACs paved the way for the development of numerous less-invasive hemodynamic monitors over the past 3 decades. These devices estimate cardiac output using concepts such as pulse contour and pressure analysis, transpulmonary thermodilution, carbon dioxide rebreathing, impedance plethysmography, Doppler ultrasonography, and echocardiography. Herein, the authors review the conception, technologic advancements, and modern use of PACs, as well as the criticisms regarding the clinical utility, reliability, and safety of PACs. The authors comment on the current understanding of the benefits and limitations of alternative hemodynamic monitors, which is important for providers caring for critically ill patients.
