Abstract
INTRODUCTION Several surgical teams have developed so-called minimally invasive esophagectomy techniques with the intention of decreasing post-operative complications. The goal of this report is to determine the feasibility, reproducibility, morbidity and mortality of esophagectomy and intrathoracic anastomosis via thoracoscopy. METHODS This retrospective series included 114 consecutive non-selected patients who underwent Lewis Santy type esophagectomy between 2016 and 2020. The procedure was performed via abdominal laparoscopy, thoracoscopy with the patient in a supine position, without selective intubation, with intra-thoracic semi-mechanical triangular esophagogastric anastomosis. RESULTS Mean patient age was 62.8years. Conversion from laparoscopy to laparotomy was required in three patients (2.6%); no patient required conversion from thoracoscopy to thoracotomy. A semi-mechanical triangular esophagogastric anastomosis was successfully performed in all patients. Median duration of hospital stay was 16 (8-116) days. Mortality was 2.6%; 34 patients (29.8%) had major complications, 55 (48%) had a respiratory complication. The leakage rate was 12.3%; most were type I. Only 5.2% required an additional procedure. There was no mortality. CONCLUSION The analysis of this consecutive series found that this operative technique was reproducible and reliable. These results need to be confirmed by other studies. Pulmonary morbidity was high and remains the main challenge in this type of surgery.

Abstract
Abstract
Introduction
Despite the increasing availability of early reperfusion, acute ischemic stroke (AIS) is still burdened by high mortality and long-time disability. Junctional protein associated with Coronary Artery Disease (JCAD) was associated to multiple cardiovascular disorders, but its role in AIS has not been investigated so far.
Purpose
To investigate the role of endothelial JCAD in the pathogenesis of AIS and its potential as a therapeutic target.
Methods
Cerebral ischemia was induced by transient Middle Cerebral Artery Occlusion (tMCAO) in mice with either global or endothelial-specific JCAD genetic deletion, and littermate controls. Stroke size was assessed ex-vivo by tetrazolium chloride staining 48 hours after reperfusion. For neurological assessment, RotaRod Test and Bederson score were recorded 24 and 48 hours after reperfusion. In vivo silencing of JCAD was achieved by intravenous injection of a JCAD small interfering RNA (siRNA) after tMCAO.
In parallel, JCAD silencing was performed in vitro in human brain microvascular endothelial cells (HBMVECs) using siRNA transfection, followed by hypoxia/reoxygenation (H/R) injury. Cell death and trans-endothelial electrical resistance (TEER) were measured by LDH assay and electrical cell-substrate impedance sensing, respectively. Molecular mechanisms were investigated in vivo by immunohistochemistry and in vitro by Western blot, respectively.
Lastly, JCAD plasma levels were measured by ELISA in two independent cohorts of patients with AIS.
Results
The expression of JCAD was up-regulated in the ipsilateral hemisphere of stroke in wild-type mice. Both global and endothelial-specific JCAD knockout mice displayed reduced stroke size after tMCAO and a significantly improved Bederson score. Similarly, mice with post-ischemic JCAD silencing had a reduced stroke size and a better motor performance at the RotaRod test (Figure 1).
In vitro, JCAD-silenced HBMVECs showed a reduced cell death rate and a higher TEER after H/R injury, compared to controls. JCAD-silenced HBMVECs also had an increased phosphorylation of Akt. After treatment with the Akt/PI3K inhibitor Wortmannin, JCAD-silenced HBMVECs showed similar TEER and cell death rates to non-silenced cells, following H/R (Figure 2).
Lastly, an increase of circulating levels of JCAD was observed in patients with AIS within 24 hours from symptoms onset. Furthermore, higher levels of JCAD at the time of hospitalization were associated with a higher risk of death within 90 days after the event.
Conclusions
JCAD expression is associated with a larger brain damage in mice in vivo and with a higher mortality in patients. In vitro results suggest that JCAD plays a pivotal role in regulating the integrity of endothelium after a H/R injury, inducing cellular death through the inhibition of the Akt/PI3K pathway. Thus, post-ischemic silencing of JCAD may represent a therapeutic strategy to improve the prognosis of patients with acute ischemic stroke.

Abstract
BACKGROUND Pancreatic metastases (PM) are rare, comprising 3% of pancreatic tumours removed in sizable series of operations. This report presents the first case of metachronous pancreatic metastases from rhabdomyosarcoma successfully treated by pancreaticoduodenectomy. CASE REPORT A 19-year old man was admitted with a tumor in the head of the pancreas, 1 year after undergoing removal of an alveolar RMS from the right hand. . Computed tomography (CT) scan demonstrates a solitary hypodence tumour of the pancreas. The patient underwent a pancreaticoduodenectomy and the postoperative course was uneventful. Pathologic examination confirmed the metastatic alveolar RMS without lymph node involvement. At most recent follow-up, 36 months after pancreaticoduodenectomy, the patient has no evidence of disease. CONCLUSION Although rare, rhabdomyosarcoma can metastasize to the pancreas. The surgeons must be aware of this complication, and that such pancreatic metastases are potentially resectable with a good long term outcome.

Abstract
AbstractFat-level measurements used to indicate individual body condition and fitness are useful only when taken at a region along the body where fat responds to variations in caloric intake. Investigations to identify appropriate species-specific regions are limited, especially for cetaceans that have a specialized fat (blubber) that serves as an energy reserve and provides insulation. Over 18 mo, body mass of six pilot whales varied (range: 50-172 kg), and although caloric intake increased when water temperatures were lower, generally the best-fitting state-space model for length-adjusted mass was based on a single factor, caloric intake. After correcting for body length (range: 330-447 cm), the slope for blubber thickness and "blubber ring" thickness (average blubber thickness along a girth) in relation to body mass was positive and had a P value of <0.10 at six of 16 blubber measurement sites and one of five girth measurement sites, respectively. The slope for body girth (a reflection of changes in underlying blubber thickness) in relation to body mass was positive and had a lower P value ([Formula: see text]) at three of five girth measurement sites. Results indicate that blubber from the anterior insertion of the pectoral fins to the posterior insertion of the dorsal fin is the most metabolically active region. This region includes the midflank site, a location where blubber thickness measurements have historically been taken to monitor cetacean body condition. Conversely, blubber in the peduncle region was comparatively inert. These findings must be considered when measuring blubber thickness and body width (i.e., photogrammetry) to monitor the condition of free-ranging cetaceans.

Communicative competencies anchored longitudinally - the curriculum "personal and professional development" in the model study programme in undergraduate medical education at the University of Witten/Herdecke. GMS JOURNAL FOR MEDICAL EDUCATION 2021; 38:Doc57. [PMID: 33824893 PMCID: PMC7994876 DOI: 10.3205/zma001453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 07/16/2020] [Accepted: 08/13/2020] [Indexed: 06/12/2023]
Abstract
Background: In October 2018, the University of Witten/Herdecke (UW/H) launched the new reformed medical education programme called Medicine 2018+. A major innovation compared to the existing model programme was the introduction of thematic focuses. A longitudinal communication skills curriculum was integrated into the new thematic focus "professional and personal development - inner work" (IAP). With the start of the new programme, the IAP curriculum has been built step-by-step over time, i.e. the first four semesters have already been implemented, the following semesters are being planned. Project description: IAP aims to provide students with patient-centred medicine. Five areas of competence were defined: Doctor-patient communication, team competence, staying healthy, my paths to becoming a doctor, medicine and society. The focus of this article is on the communication curriculum. The first year of study focusses on the training of basic communication skills. In the 2nd year of study, students practice these basic skills in small groups with simulated patients (SP), whereby the emphasis in the 3rd semester is on history taking and in the 4th semester is on sharing information. In the 3rd semester, students complete a communication station in an OSCE. From the 5th semester onwards, the focus of training is on the consolidation of basic and advanced communication skills, which can be applied in clinical clerkships, and the reflection of clinical experiences. Key didactic elements are, in addition to teaching the theoretical basics, experience-based small group work with and without SP, feedback and reflection. The evaluation of the summer semester 2020 showed high agreement ratings of the students regarding the overall satisfaction with the individual courses (83-100% agreement). Discussion: The introduction of IAP has been very positively received by the students. Challenges are the adequate handling of the increasing student workload when planning new courses, the implementation of a longitudinal e-portfolio as well as the recruitment and training of clinical teachers and SPs. Conclusion: As the evaluation results of the summer semester 2020 show, the first steps of implementing a longitudinal communication curriculum at UW/H have been successful. Helpful strategies were the orientation on published examples from other faculties as well as regular feedback and discussions with students and teachers in order to adapt and integrate educational considerations into the existing model programme in Witten.

Abstract
INTRODUCTION Monitoring of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) in pig farms is performed usually by testing for antibodies against PRRSV in serum samples. A new method is the detection of PRRSV antibodies in porcine saliva. In this study serum samples and saliva were collected in nine farms suspicious for PRRSV and tested for the presence of PRRSV antibodies. In total 220 serum and 41 saliva samples were taken from pigs at the age of 8 weeks (± 1 week). One saliva and one pooled serum sample (1:5) were tested from each pen. In total 11 (Cut-off 0.4/0.3) or 14 (Cut-off 0.2) serum samples and 23 saliva out of 41 pens were positive for PRRSV antibodies. Cohen`s Kappa testing showed a moderate agreement (κ = 0.446). Saliva samples compared to pooled serum samples were very sensitive, the specificity was 60 and 67, respectively.

To zoom or not to zoom - the training of communicative competencies in times of Covid 19 at Witten/Herdecke University illustrated by the example of "sharing information". GMS JOURNAL FOR MEDICAL EDUCATION 2020; 37:Doc83.

Abstract
Since October 2018, a longitudinal communication curriculum for medical students has been implemented at Witten/Herdecke University. In the summer semester 2020, the concept for the 4th preclinical semester included a practical training on "sharing information", which consisted of three two-hour face-to-face sessions with simulated patients (SP). Due to the Covid 19 pandemic, teaching was changed to an inverted classroom concept combining asynchronous and synchronous teaching. The students worked at the beginning of the semester on an e-learning module of the learning platform docCom.deutsch on the topic "sharing information" using reflection and processing tasks. In two digital sessions, the students then were able to practice discharge interviews and discussions about risk communication illustrated by the example of screening methods for cancer prevention. In the first zoom session, students practiced in role-plays among themselves. In the second zoom session, they practiced with SP. The evaluation results revealed that 76% of the responding students considered working with the e-learning module as a good preparation for the interviews. According to the evaluation results, satisfaction with the Zoom meeting including SP contact was slightly higher than those with role-plays among themselves. Although the group atmosphere was rated by all responding students as conducive to learning, almost half of them confirmed that using Zoom significantly impaired the atmosphere (47%). In retrospect, the conversion of the communication training to a digital format worked better than expected from both the perspective of teachers and students. The students explicitly appreciated working with SP. From the teachers' perspective, some specific aspects of successful communication were difficult to reflect on, e.g. non-verbal communication. The use of e-learning as a preparation for practical exercises has proven successful and will be continued in the future.

Abstract
The Covid-19 pandemic is changing the organization of healthcare and has a direct impact on digestive surgery. Healthcare priorities and circuits are being modified. Emergency surgery is still a priority. Functional surgery is to be deferred. Laparoscopic surgery must follow strict rules so as not to expose healthcare professionals (HCPs) to added risk. The question looms large in cancer surgery-go ahead or defer? There is probably an added risk due to the pandemic that must be balanced against the risk incurred by deferring surgery. For each type of cancer-colon, pancreas, oesogastric, hepatocellular carcinoma-morbidity and mortality rates are stated and compared with the oncological risk incurred by deferring surgery and/or the tumour doubling time. Strategies can be proposed based on this comparison. For colonic cancers T1-2, N0, it is advisable to defer surgery. For advanced colonic lesions, it seems judicious to undertake neoadjuvant chemotherapy and then wait. For rectal cancers T3-4 and/or N+, chemoradiotherapy is indicated, short radiotherapy must be discussed (followed by a waiting period) to reduce time of exposure in the hospital and to prevent infections. Most complex surgery with high morbidity and mortality-oesogastric, hepatic or pancreatic-is most often best deferred.

Abstract
La pandémie due au COVID-19 modifie l’organisation des soins et change la réalisation de la chirurgie digestive. Les priorités sanitaires et les circuits de soins sont modifiés. La chirurgie d’urgence reste prioritaire. Les interventions pour chirurgie fonctionnelles sont à reporter. La chirurgie par laparoscopie doit suivre des règles strictes pour ne pas exposer les professionnels à un surrisque. Le questionnement principal concerne la chirurgie oncologique, opérer ou reporter ? Il existe probablement un sur risque opératoire induit par la pandémie qui doit être mis en balance avec le retard de prise en charge chirurgical. Pour chaque type de cancer, colon, pancréas, œsogastrique, hépatocarcinome, la morbi-mortalité est rappelée et mise en parallèle avec le risque oncologique lié au retard à la chirurgie et/ou au temps de doublement de la tumeur. Cette comparaison permet de proposer des stratégies, ainsi pour les cancers coliques (T1-2, N0), il est souhaitable de retarder la chirurgie. Pour les lésions coliques avancées, il semble prudent de recommander une chimiothérapie néo adjuvante et d’attendre. Pour les cancers du rectum T3-4 et/ou N+, une radio-chimiothérapie est indiquée, une radiothérapie courte devra être discutée (suivie d’une période d’attente) afin de réduire le temps d’exposition à l’hôpital et d’éviter les infections. La majorité des chirurgies complexes à forte morbi-mortalité, œsogastrique, hépatique ou pancréatique doivent sans doute le plus souvent être reportée.

Impact of cirrhosis in patients undergoing laparoscopic liver resection in a nationwide multicentre survey. Br J Surg 2020; 107:268-277.

Abstract
BACKGROUND The aim was to analyse the impact of cirrhosis on short-term outcomes after laparoscopic liver resection (LLR) in a multicentre national cohort study. METHODS This retrospective study included all patients undergoing LLR in 27 centres between 2000 and 2017. Cirrhosis was defined as F4 fibrosis on pathological examination. Short-term outcomes of patients with and without liver cirrhosis were compared after propensity score matching by centre volume, demographic and tumour characteristics, and extent of resection. RESULTS Among 3150 patients included, LLR was performed in 774 patients with (24·6 per cent) and 2376 (75·4 per cent) without cirrhosis. Severe complication and mortality rates in patients with cirrhosis were 10·6 and 2·6 per cent respectively. Posthepatectomy liver failure (PHLF) developed in 3·6 per cent of patients with cirrhosis and was the major cause of death (11 of 20 patients). After matching, patients with cirrhosis tended to have higher rates of severe complications (odds ratio (OR) 1·74, 95 per cent c.i. 0·92 to 3·41; P = 0·096) and PHLF (OR 7·13, 0·91 to 323·10; P = 0·068) than those without cirrhosis. They also had a higher risk of death (OR 5·13, 1·08 to 48·61; P = 0·039). Rates of cardiorespiratory complications (P = 0·338), bile leakage (P = 0·286) and reoperation (P = 0·352) were similar in the two groups. Patients with cirrhosis had a longer hospital stay than those without (11 versus 8 days; P = 0·018). Centre expertise was an independent protective factor against PHLF in patients with cirrhosis (OR 0·33, 0·14 to 0·76; P = 0·010). CONCLUSION Underlying cirrhosis remains an independent risk factor for impaired outcomes in patients undergoing LLR, even in expert centres.

Abstract
BACKGROUND BRAF mutation is associated with a poor prognosis in patients with metastatic colorectal cancer. For patients with resectable colorectal liver metastases (CRLMs), the prognostic impact of BRAF mutation is unknown and the benefit of surgery debated. This nationwide intergroup (ACHBT, FRENCH, AGEO) study aimed to evaluate the oncological outcome of patients undergoing liver resection for BRAF-mutated CRLMs. METHODS The study included patients who underwent resection for BRAF-mutated CRLMs in 24 centres between 2012 and 2016. A case-matched comparison was made with 183 patients who underwent resection of CRLMs with wild-type BRAF during the same interval. RESULTS Sixty-six patients who underwent resection for BRAF-mutated CRLMs in 24 centres were compared with 183 patients with wild-type BRAF. The 1- and 3-year disease-free survival (DFS) rates were 46 and 19 per cent for the BRAF-mutated group, and 55·4 and 27·8 per cent for the group with wild-type BRAF (P = 0·430). In multivariable analysis, BRAF mutation was not associated with worse DFS (hazard ratio 1·16, 95 per cent c.i. 0·72 to 1·85; P = 0·547). The 1- and 3-year overall survival rates after surgery were 94 and 54 per cent respectively among patients with BRAF mutation, and 95·8 and 82·9 per cent in those with wild-type BRAF (P = 0·004). Median survival after disease progression was 23·0 (95 per cent c.i. 11·0 to 35·0) months among patients with mutated BRAF and 44·3 (35·9 to 52·6) months in those with wild-type BRAF (P = 0·050). Multisite disease progression was more common in the BRAF-mutated group (48 versus 29·8 per cent; P = 0·034). CONCLUSION These results support surgical treatment for resectable BRAF-mutated CRLM, as BRAF mutation by itself does not increase the risk of relapse after resection. BRAF mutation is associated with worse survival in patients whose disease relapses after resection of CRLM, as for non-metastatic colorectal cancer.

Abstract
The use of virtual simulations in nursing is an innovative strategy that is increasing in application. There are several terms related to virtual simulation; although some are used interchangeably, the meanings are not the same. This article presents examples of virtual simulation, virtual worlds, and virtual patients in continuing education, staff development, and academic nursing education. Virtual simulations in nursing use technology to provide safe, as realistic as possible clinical practice for nurses and nursing students. Virtual simulations are useful for learning new skills; practicing a skill that puts content, high-order thinking, and psychomotor elements together; skill competency learning; and assessment for low-volume, high-risk skills. The purpose of this article is to describe the related terms, examples, uses, theoretical frameworks, challenges, and evidence related to virtual simulations in nursing.

Abstract
Purpose: Given the high attrition rate in the field of academic surgery, we aimed to characterise the professional and personal situations of female and male academic surgeons as well as to gather data on their respective perceptions of career advancement and work satisfaction. Methods: We conducted a cross-sectional survey in Germany, inviting all identifiable academically highly qualified female surgeons and their male counterparts in a 1:2 ratio to participate. An anonymous 103-item online questionnaire was designed and the data collected between July and September 2014. Results: The questionnaire was sent to 93 female and 200 male surgeons, of whom 63 women (67.7%) and 70 men (35.0%) replied. The average age was 47.5 and 47.1 years, respectively. Respondents identified ‘high degree of expertise', ‘ambition', and ‘clarity of one's professional aims' as important factors affecting professional career development. Both groups felt ‘workload', ‘working hours/shifts', and ‘gender' to be a hindrance, the latter of significantly greater importance to female surgeons. The mean work satisfaction scores were high in both female (69.5%) and male (75.7%) surgeons. The predictors ‘support from superiors' (standardised β coefficient = 0.41) and ‘manual aptitude' (β = 0.41) contributed incrementally to the variance in ‘high degree of work satisfaction' (90-100%) observed for female surgeons. However, childcare provided by ‘kindergarten/crèche/after-school care' had the greatest negative predictive value (β = -1.33). Conclusions: Although there are many parallels, female faculty members experience the culture of academic surgery to some extent differently from their male counterparts, especially when impacted by parenthood and childcare. Faculty development programmes need to develop strategies to improve perceived equality in career opportunities by respecting individuals' requirements as well as offering gender-appropriate career guidance.

Abstract
AIM OF THE STUDY During minimally invasive abdominal surgery, a laparoscope is used to film the procedure, which is transmitted to a flat screen monitor. The horizontality of the image depends on the orientation in space and the visual comfort of the surgeon. Observing the screen via a lateral angle of incidence frequently results in the camera assistant making errors in determining the horizontality of the image. Thus, what is "right" for the camera assistant is not necessarily 'right' for the surgeon. We aimed to explain the impact of these errors in laparoscope manipulation, by the description of the parallax effect. PATIENTS AND METHODS To describe this phenomenon of perceptions changing depending on the angle of view, from the basis of the parallax effect, we observed the change of position and for two observers, (the surgeon and the camera assistant) seated at two different locations, using an experimental set up (i.e., photography equipment, a screen and a pelvitrainer). RESULTS The position of the camera assistant positioned at an angle of incidence of 45° from the surgeon, the observation of the screen with a lateral incidence changes the perception of the image viewed on the screen. For correcting the conflict between the subjective visual perception of the camera assistant and the actual image horizon, the camera assistant instinctively rotates the image, which can lead to an "incorrect" image, deleterious for the surgeon. CONCLUSIONS This article introduces a previously unexplained concept in medical literature, called the parallax effect. The parallax effect results in the camera assistant making systematic errors in determining image horizontality on the screen.

Transthoracic Port Placement Increases Safety of Total Laparoscopic Posterior Sectionectomy. Ann Surg Oncol 2016; 23:2167. [PMID: 26903047 DOI: 10.1245/s10434-016-5126-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2016] [Indexed: 12/23/2022]
Abstract
BACKGROUND Anatomic posterior sectionectomy is performed infrequently due to the challenges of controlling the right posterior portal pedicle (RPPP) while preserving the anterior pedicle (RAPP), difficulty of visualizing the drainage of the right hepatic vein into the IVC, and the potential for significant blood loss during the caval and hepatovenous dissection. PATIENT A 62-year-old woman with three liver metastases to SVI and SVII from sigmoid colon cancer underwent five cycles of neoadjuvant chemotherapy with FOLFOX and bevacizumab with good response. She underwent a "Primary First" robotic low anterior rectosigmoid resection followed by a laparoscopic posterior sectionectomy. TECHNIQUE The patient was placed in a Modified French Position. As previously described, a transthoracic trocar was placed for optimal laparoscopic visualization and access of the superior retrohepatic IVC and drainage of the right hepatic vein into IVC. Intraoperative ultrasound was crucial to assess tumor location, define transection plane, and preserve flow to RAPP before division of RPPP. The parenchymal transection follows an oblique angle and exposes the right hepatic vein. CONCLUSIONS Transthoracic port placement augments the safety of the dissection along the IVC inferiorly and the right hepatic vein superiorly due to direct visualization. Also, it provides a direct instrument-to-target axis without the typical fulcrum of dissecting the postero/superior liver. Laparoscopic ultrasound is critical to confirm preserved flow to the RPPP and guide the parenchymal transection. Liver volumetry should be obtained before surgery to determine adequate future liver remnant if conversion to a right lobectomy becomes necessary.

Total Laparoscopic Central Pancreatectomy with Pancreaticogastrostomy for High-Risk Cystic Neoplasm. Ann Surg Oncol 2015; 23:1035.

Abstract
BACKGROUND Organ-sparing pancreatic resection is important in prophylactic surgery for cystic neoplasms. There is controversy regarding the optimal surgical approach for pancreatic lesions in the neck or proximal body of the pancreas. Central compared with distal pancreatectomy is technically more challenging, but preserves more functional pancreatic tissue. Because of the prophylactic nature of the surgery and long survival of patients with benign and borderline malignant lesions, surgeons need to stratify greater importance to surgical morbidity and sparing pancreatic parenchyma. PATIENT The patient is a 59-year-old active woman with a symptomatic cystic neoplasm of the pancreas exhibiting high-risk imaging features. The cyst of 2.2 × 1.8 cm in the body of the pancreas was impinging on the portal venous confluence. TECHNIQUE The patient was positioned in the French Position, the lesser sac was opened, and the pancreatic body exposed. A retropancreatic tunnel was created with staple division of the neck. The body was mobilized off the portal vein and splenic vessels transected. A retrogastric pancreaticogastrostomy was sewn through an anterior gastrotomy. The stent was delivered past the pylorus to decrease pancreatic enzymatic activation. Pathology demonstrated a mixed predominantly branch duct IPMN with multifocal high grade dysplasia and PanIN3. CONCLUSIONS Laparoscopic ultrasound helps in defining cyst borders, and minimal blood loss optimizes visualization during the dissection. A minimally invasive pancreaticogastrostomy created through an anterior gastrotomy is technically feasible and safe. This approach can minimize the morbidity of prophylactic pancreatic surgery for patients with cystic neoplasms. Nevertheless, it should not compromise safety, oncologic completeness, or an organ-sparing approach.

Abstract
BACKGROUND Although recent reports have suggested potential benefits of the laparoscopic approach in patients requiring major hepatectomy, it remains unclear whether conversion to open surgery could offset these advantages. This study aimed to determine the risk factors for and postoperative consequences of conversion in patients undergoing laparoscopic major hepatectomy (LMH). METHODS Data for all patients undergoing LMH between 2000 and 2013 at two tertiary referral centres were reviewed retrospectively. Risk factors for conversion were determined using multivariable analysis. After propensity score matching, the outcomes of patients who underwent conversion were compared with those of matched patients undergoing laparoscopic hepatectomy who did not have conversion, operated on at the same centres, and also with matched patients operated on at another tertiary centre during the same period by an open laparotomy approach. RESULTS Conversion was needed in 30 (13·5 per cent) of the 223 patients undergoing LMH. The most frequent reasons for conversion were bleeding and failure to progress, in 14 (47 per cent) and nine (30 per cent) patients respectively. On multivariable analysis, risk factors for conversion were patient age above 75 years (hazard ratio (HR) 7·72, 95 per cent c.i. 1·67 to 35·70; P = 0·009), diabetes (HR 4·51, 1·16 to 17·57; P = 0·030), body mass index (BMI) above 28 kg/m(2) (HR 6·41, 1·56 to 26·37; P = 0·010), tumour diameter greater than 10 cm (HR 8·91, 1·57 to 50·79; P = 0·014) and biliary reconstruction (HR 13·99, 1·82 to 238·13; P = 0·048). After propensity score matching, the complication rate in patients who had conversion was higher than in patients who did not (75 versus 47·3 per cent respectively; P = 0·038), but was not significantly different from the rate in patients treated by planned laparotomy (79 versus 67·9 per cent respectively; P = 0·438). CONCLUSION Conversion during LMH should be anticipated in patients with raised BMI, large lesions and biliary reconstruction. Conversion does not lead to increased morbidity compared with planned laparotomy.

Abstract
BACKGROUND Surgical resection of pancreatic metastasis (PM) is the only reported curative treatment for renal cell carcinoma. However, there is currently little information regarding very long-term survival. The primary objective of this study was to determine the 10-year survival of this condition using the largest surgical series reported to date. METHODS Between May 1987 and June 2003, we conducted a retrospective study of 62 patients surgically treated for PM from renal cell carcinoma at 12 Franco-Belgian surgical centers. Follow-up ended on May 31, 2012. RESULTS There were 27 male (44 %) and 35 female (56 %) patients with a median age of 54 years [31-75]. Mean disease-free interval from resection of primary tumor to reoperation for pancreatic recurrence was 9.8 years (median 10 years [0-25]). During a median follow-up of 91 months [12-250], 37 recurrences (60 %) were observed. After surgical resection of repeated recurrences, overall median survival time was 52.6 months versus 11.2 months after nonoperative management (p = 0.019). Cumulative 3-, 5-, and 10-year overall survival (OS) rates were 72, 63, and 32 %, respectively. The corresponding disease-free survival rates were 54, 35, and 27 %, respectively. Lymph node involvement and existence of extrapancreatic metastases before PM were associated with poor overall survival. CONCLUSIONS Aggressive surgical management of single or multiple PM, even in cases of extrapancreatic disease, should be considered in selected patients to allow a chance of long-term survival.

Abstract
BACKGROUND The significance of positive para-aortic nodes in patients with resectable pancreatic carcinoma is unclear. This study sought to evaluate the accuracy of intraoperative detection and prognostic significance of these lymph nodes in patients with resected adenocarcinoma of the pancreatic head. METHODS From 2000 to 2010, para-aortic node sampling was performed prospectively in all patients before pancreatoduodenectomy. Frozen sections were created and nodes categorized as positive or negative for metastases. Surgeons were blinded to the frozen-section results. This was followed by standard histopathological assessment of corresponding paraffin-embedded, haematoxylin and eosin-stained material. Nodes considered uninvolved by this analysis were examined immunohistochemically for micrometastases. RESULTS A total of 111 consecutive patients were included, with a median follow-up of 20·8 (range 1·5-126) months. The 1-, 2- and 5-year overall survival (OS) and disease-free survival (DFS) rates were 73·6, 54·0 and 24·7 per cent, and 51·8, 28·1 and 18·8 per cent respectively. Para-aortic node involvement was always associated with peripancreatic lymph node metastasis, and was detected by frozen-section analysis in 12 patients and by haematoxylin and eosin staining in 17. Sensitivity and specificity of frozen-section examination for detecting para-aortic lymph node metastases were 71 and 100 per cent respectively. Median OS for patients with and without para-aortic node involvement on frozen-section analysis was 9·7 versus 28·5 months respectively (P = 0·012), and 15·7 versus 27·2 months (P = 0·050) when assessed by haematoxylin and eosin staining. Median DFS for patients with and without para-aortic node involvement on frozen-section examination was 5·6 versus 12·9 months respectively (P = 0·041), and 8·4 versus 12·9 months (P = 0·038) for haematoxylin and eosin analysis. The presence of micrometastases in para-aortic nodes was not significantly associated with altered OS or DFS. CONCLUSION Para-aortic node sampling with frozen-section examination detects distant lymphatic involvement reliably. It should be performed systematically. When metastases are found, they should be considered a contraindication to pancreatic resection.

Abstract
BACKGROUND Alpha-1 antitrypsin deficiency is under-recognized. We hypothesized that respiratory therapists (RTs) could help improve the detection rate of individuals with alpha-1 antitrypsin deficiency. The American Association for Respiratory Care (AARC) and Alpha-1 Foundation recently collaborated to create an online alpha-1 antitrypsin deficiency training program for RTs. This study aimed to determine (1) the rate of RT enrollment in the training program, (2) the rates of detecting individuals with alpha-1 antitrypsin deficiency referred for testing by RTs who took the online course ("trained RTs"), and (3) the genotype distribution of referred individuals found to have alpha-1 antitrypsin deficiency. METHODS Patients referred by trained RTs submitted blood samples for alpha-1 antitrypsin deficiency testing through the existing Alpha-1 Coded Testing (ACT) Study. The AARC sent the first 3 digits of trained RTs' zip codes to the study data center. Investigators there matched those zip codes with those of patients in the ACT Study who reported being referred to the study by an RT. The data center determined the number of these patients with alpha-1 antitrypsin deficiency and their genotypes. Investigators then aggregated the data and calculated the RT enrollment rate, the rate of detecting individuals with alpha-1 antitrypsin deficiency, and the distribution of genotype results. RESULTS Between July 1, 2012, and June 30, 2013, 378 RTs took the online program (mean 21/mo), and 326 patients reported that they were referred for testing by an RT. Thirty-four percent (111/326) of these referrals were by trained RTs (6.2/mo). Sixty-two test blood kits were returned by these 111 referred patients and analyzed (4/mo). Two of these specimens (3.2%) were from patients identified as having severe alpha-1 antitrypsin deficiency (PI*ZZ) and one from a patient with PI*SZ (serum level 14 μM). Twenty-four percent were from PI*MZ heterozygotes. CONCLUSIONS A program to educate RTs about alpha-1 antitrypsin deficiency was associated with referral of patients for alpha-1 antitrypsin deficiency testing and high rates of detecting individuals with severe alpha-1 antitrypsin deficiency.

Abstract
The palliative approach offers significant and practical care throughout the treatment of the dialysis patient until death. Varied aspects of quality of life for patients can be improved. It is possible to relieve symptoms such as sleep disorders, pain, constipation and pruritus, which, according to the present survey, are common symptoms. The treatment of dying dialysis patients or the possibility and legitimization of discontinuing treatment are complex, controversial issues with ethical and legal implications. But these issues have not yet been adequately dealt with by the nephrological community. The nurses who encounter patients daily, who constantly deal with great suffering and who lack tools to help, can lead the practice in this field within the framework of inter-disciplinary team work. In light of the obvious need for progress in this area, appropriate training courses should be considered. The implementation of the palliative approach in dialysis units could be a challenge for all of us in the coming years.

Abstract
In an era of specialty medicine, genetic counselors are becoming increasingly focused in their service provision. The Alpha-1 Association Genetic Counseling Program, established in September 2007, specializes in confidential toll-free genetic counseling provided by a certified genetic counselor for Alpha-1 Antitrypsin deficiency, a co-dominant condition associated with lung and/or liver disease. The program received more than 600 callers in its first 2 years. Sixty-seven percent of new callers were family members, carriers, or health professionals. The number of callers increased between the first 2 years, with the greatest increases being family members and health professionals. Testing options and explanation of results encompassed 60% of initial reasons for calls. Seventy-two percent of referrals came from family and friends, test result letters, and the Alpha-1 Association. Between year 1 and 2 family member referrals showed the largest increase. This disease-specific genetic counseling program provides a model that may be useful for other rare disease communities.
