ABSTRACT
INTRODUCTION: When authorship disputes arise in academic publishing, research institutions may be asked to investigate the circumstances. We evaluated the association between the prevalence of misattributed authorship and trust in the institution involved. METHODS: We measured trust using a newly validated Opinion on the Institution's Research and Publication Values (OIRPV) scale (range 1-4). Mayer and Davies' Organizational Trust for Management Instrument served as control. Association between publication misconduct, gender, institution type, policies, and OIRPV-derived Trust Scores were evaluated. RESULTS: A total of 197 responses were analyzed. Increased reporting of authorship misconduct, such as gift authorship, author displacement within the authors' order on the byline, and ghost authorship, were associated with low Trust Scores (P<0.001). Respondents from institutions whose administration had made known (declared or published) their policy on authorship in academic publications awarded the highest Trust Scores (median 3.06, interquartile range 2.25 to 3.56). Only 17.8% favored their administration as the best authority to investigate authorship dispute honestly. Of those who did not list the administration as their preferred option for resolving disputes, 58.6% (95/162) provided a Trust Score <2.5, which conveys mistrust in the institution. CONCLUSIONS: Increased reporting of publication misconducts such as gift authorship, author displacement within the order of the authors' byline, and ghost authorship was associated with lower Trust Scores in the research institutions. Institutions that made their policies known were awarded the highest Trust Scores. Our results question whether the research institutions' administrations are the appropriate authority for clarifying author disputes in all cases.
ABSTRACT
PURPOSE: Current practice allows for surgery for acute appendicitis to be delayed up to 24 h in the belief that there will be no increase in complicated appendicitis rates. We evaluated the combined effect of Patient Time (between symptom onset and hospital admission) and Hospital Time (between hospital admission and surgery) on the surgical outcome. We hypothesized that in patients with a short Patient Time, increased Hospital Times will be associated with a higher rate of complicated appendicitis, even in patients operated within 24 h. METHODS: Retrospective evaluation of medical files of patients operated for acute appendicitis between 12/2006 and 12/2016. RESULTS: Of 2749 patients with acute appendicitis included in this analysis, 818 (29.8%) were admitted with symptom onset the same day as admission, 577 (21.0%) reported symptom onset had started the previous day but less than 24 h before admission, and 1354 (49.3%) had over 24 h of symptoms. In patients with symptom onset the same day, a gradual increase in the rate of complicated appendicitis was noted with increasing Hospital Times (≤ 6 h-6.3%; 6-12 h-9.9%; 12-18 h-14.7%; and 18-24 h-12.7%; p = 0.017). In all other patients no differences in the rate of complicated appendicitis were noted as long as the patients were operated within 24 h of admission. CONCLUSION: In patients with a short Patient Time, delaying operation is associated with an increased rate of complicated appendicitis and this group of patients should be prioritized for early surgery.

En los tumores mamarios grandes en relación con el tamaño de la mama se requieren métodos reconstructivos complejos. Se describe un método alternativo de cierre que permite el cierre primario del defecto mediante la relajación de la piel y el uso de un sistema de relajación de la tensión. Estos sistemas de relajación permiten el cierre primario inmediato de grandes defectos cutáneos en pacientes con tumores que son grandes en comparación con el tamaño de la mama. El cierre de la herida quirúrgica sin tensión en los bordes permite una curación temprana y una rápida movilización con buena funcionalidad. Una curación óptima facilita la radioterapia postoperatoria a tiempo sin problemas en la reconstrucción
In mammary tumors that are large relative to breast-size, complex reconstructive methods are required. We describe an alternative system of closure. In circumstances such as this, primary closure of this skin defect may be enabled by stress relaxation of the skin and the use of a tension-relief system. Tension-relief systems secures immediate primary closure of large skin defects in patients with large for breast-size tumors by placing the tension away from the skin edges. This enables early skin closure and rapid mobilization with good functionality. Optimal healing facilitates postoperative radiotherapy on time without reconstruction failure

Informed consent forms (ICFs) in clinical trials are the only objective testimony whether the information provided to participants is comprehensive and presented in an accessible language. We evaluated the length of Hebrew ICFs and their English translations and evaluated the readability of the latter. In fifteen clinical trials (5 with pharmacogentic sub-study), the median number (IQR) of pages and words were: English clinical ICFs - 16 pages (13,18) and 7360 words (6959,8289); Hebrew clinical ICFs - 12 pages (10,14), 5807 words (5258,6403); English pharmacogenetics ICFs - 7 pages (4,11), 2930 words (2234,5100); Hebrew pharmacogenetics ICFs - 5 pages (4,8.5), 2273 words (1663,3889); the two English ICFs combined - 23 pages (18;29.5), 10,820 words (9515,15,600); and the two Hebrew ICFs combined - 19 pages (16,23), 8258 words (7340,10,515). Differences between the Hebrew clinical trial ICFs and their English translations were significant (p < 0.001). Median (IQR) Flesch Reading Ease scores for the clinical and the pharmacogenetics ICFs were 48.4 (42.7, 49.9) and 42.2 (41.7,42.65), respectively. Thirteen studies were multinational. Twelve were conducted simultaneously in the United States, where an assessment of readability scores is customary. In conclusion, the consent forms evaluated in this study were long, and readability scores were low.

BACKGROUND: We determined whether increasing early imaging (in the emergency department) was associated with earlier surgery and a decrease in complicated appendicitis. METHODS: Retrospective study; 3013 operations between 12/2006-12/2016. RESULTS: Early imaging increased from 13.1% to 74.1%, mostly due to increasing use of ultrasound. Negative appendectomies decreased from 10.7% to 5.1% (pâ¯<â¯0.001). Ultrasound was diagnostic in 80.5%. The false positive rate of ultrasound was 4%. Median time to surgery following positive ultrasound was 7.4â¯h (IQR 5.8-9.4), shorter compared to no early imaging (13.3â¯h, IQR 7.2-20.0; pâ¯<â¯0.001). However, median time to surgery following inconclusive and negative ultrasound was 11.5â¯h (IQR 8.7-16.1) and 17.0â¯h (IQR 10.3-26.7) respectively. The incidence of complicated appendicitis was 40% and 37.7%, higher than 21.5% in patients with positive US (pâ¯<â¯0.001). CONCLUSIONS: Early imaging resulted in earlier surgery but did not reduce the incidence of complicated appendicitis. Ultrasound averted the need for CT in the majority of patients. When ultrasound was negative or inconclusive, time to surgery was delayed and the rate of complicated appendicitis higher.

ABSTRACT
In mammary tumors that are large relative to breast-size, complex reconstructive methods are required. We describe an alternative system of closure. In circumstances such as this, primary closure of this skin defect may be enabled by stress relaxation of the skin and the use of a tension-relief system. Tension-relief systems secures immediate primary closure of large skin defects in patients with large for breast-size tumors by placing the tension away from the skin edges. This enables early skin closure and rapid mobilization with good functionality. Optimal healing facilitates postoperative radiotherapy on time without reconstruction failure.

INTRODUCTION: Gastrointestinal perforation is a well-known phenomenon among patients presented to emergency rooms. Common causes for perforation are gastric and duodenal ulcers, colon tumors and trauma. Some patients are operated on immediately due to the clear clinical picture of acute abdomen. The most accurate imaging is the abdominal CT scan. Conventional X-rays remain the first choice in the case of GI tract perforations. Our clinical observation is that in many cases X-ray studies are not sufficient for the decision-making process in patients with previous abdominal surgeries. AIMS: The purpose of this study was to evaluate the impact of X-rays on the decision-making process in patients with previous abdominal surgery. METHODS: A retrospective evaluation was conducted of chest/abdominal X-rays, computed tomography findings and the surgeries reports of patients admitted due to GI perforation. RESULTS: The study population of 69 patients was divided into two groups. In group 1: patients without previous abdominal surgery, X-rays of 27 patients (69.2%) were found positive for free air. In group 2: patients with previous abdominal surgeries, 16 patients demonstrated free air on chest/abdominal X-rays. The sensitivity in group 2 (53.3%) was found significantly lower compared to group 1 (69.2 %). The difference between the groups was not statistically significant; 19 of 30 (63.3%) patients with previous abdominal operations needed abdominal CT scan before final surgical decision in comparison to 38.5% of the patients without previous abdominal operations. CONCLUSIONS: Based on these results we recommend not routinely performing X-rays in patients with previous abdominal surgery. Urgent computed tomography should be the first imaging modality. DISCUSSION: In patients with previous abdominal surgeries, free air is visible only in half the patients in routine X-ray imaging. A significant number of those patients needed abdominal CT scan. Our study demonstrated that chest and abdominal plain radiography films are insufficient for the decision-making process in patients with previous abdominal operations. A multi-center prospective study is required in order to validate our findings.

BACKGROUND: Extremities are commonly injured following bomb explosions. The main objective of this study was to evaluate the prevalence of hemorrhagic shock (HS) in victims of explosion suffering from extremity injuries. METHODS: Retrospective study based on a cohort of patient records maintained in one hospital's mass casualty registry. RESULTS: Sixty-six victims of explosion who were hospitalized with extremity injuries were identified and evaluated. Sixteen (24.2%) of these were hemodynamically unstable during the first 24 h of treatment. HS could be attributed to associated injuries in seven of the patients. In the other nine patients, extremity injury was the only injury that could explain HS in seven patients and the extremity injury was a major contributor to HS together with another associated injury in two patients. In those 9 patients, in whom the extremity injury was the sole or major contributor to HS, a median of 10 (range 2-22) pRBC was transfused during the first 24 h of treatment. Six of the nine patients were in need of massive transfusion. Fractures in both upper and lower extremities, Gustilo IIIb-c open fractures and AIS 3-4 were found to be risk factors for HS. CONCLUSIONS: Ample consideration should be given to patients with extremity injuries due to explosions, as these may be immediately life threatening. Tourniquet use should be encouraged in the pre-hospital setting. Before undertaking surgery, emergent HS should be considered in these patients and prevented by appropriate resuscitation.

PURPOSE: Indications for nipple-sparing mastectomy (NSM) have broadened to include the risk reducing setting and locally advanced tumors, which resulted in a dramatic increase in the use of NSM. The Oncoplastic Breast Consortium consensus conference on NSM and immediate reconstruction was held to address a variety of questions in clinical practice and research based on published evidence and expert panel opinion. METHODS: The panel consisted of 44 breast surgeons from 14 countries across four continents with a background in gynecology, general or reconstructive surgery and a practice dedicated to breast cancer, as well as a patient advocate. Panelists presented evidence summaries relating to each topic for debate during the in-person consensus conference. The iterative process in question development, voting, and wording of the recommendations followed the modified Delphi methodology. RESULTS: Consensus recommendations were reached in 35, majority recommendations in 24, and no recommendations in the remaining 12 questions. The panel acknowledged the need for standardization of various aspects of NSM and immediate reconstruction. It endorsed several oncological contraindications to the preservation of the skin and nipple. Furthermore, it recommended inclusion of patients in prospective registries and routine assessment of patient-reported outcomes. Considerable heterogeneity in breast reconstruction practice became obvious during the conference. CONCLUSIONS: In case of conflicting or missing evidence to guide treatment, the consensus conference revealed substantial disagreement in expert panel opinion, which, among others, supports the need for a randomized trial to evaluate the safest and most efficacious reconstruction techniques.

PURPOSE: Investigation of injury patterns epidemiology among car occupants may help to develop different therapeutic approach according to the seat position. The aim of the study was to evaluate and compare differences in the incidence of serious injuries, between occupants in different locations in private cars. METHODS: A retrospective study including trauma patients who were involved in motor vehicle accidents and admitted alive to 20 hospitals (6 level â trauma centers and 14 level â ¡ trauma centers). We examined the incidence of injures with abbreviated injury score 3 and more, and compared their occurrence between seat locations. RESULTS: The study included 28,653 trauma patients, drivers account for 60.8% (17,417). Front passenger mortality was 0.47% higher than in drivers. Rear seat passengers were at greater risk (10.26%) for traumatic brain injuries than front seat passengers (7.48%) and drivers (7.01%). Drivers are less likely to suffer from serious abdominal injuries (3.84%) compared to the passengers (front passengers - 5.91%, rear passengers - 5.46%). CONCLUSION: Out of victims who arrived alive to the hospital, highest mortality was found in front seat passengers. The rate of serious chest injuries was higher as well. Rear seat passengers are at greater risk for serious traumatic brain injuries. All passengers have a greater incidence of abdominal injuries. These findings need to be addressed in order to develop "customized" therapeutic policy in trauma victims.

PURPOSE: Early diagnosis of traumatic brain injury (TBI) is important for improving survival and neurologic outcome in trauma victims. The purpose of this study was to assess whether Glasgow Coma Scale (GCS) of 12 or less can predict the presence of TBI and the severity of associated injuries in blunt trauma patients. METHODS: A retrospective cohort study including 303,435 blunt trauma patients who were transferred from the scene to hospital from 1998 to 2013. The data was obtained from the records of the National Trauma Registry maintained by Israel's National Center for Trauma and Emergency Medicine Research, in the Gertner Institute for Epidemiology and Health Policy Research. All blunt trauma patients with GCS 12 or less were included in this study. Data collected in the registry include age, gender, mechanism of injury, GCS, initial blood pressure, presence of TBI and incidence of associated injuries. Patients younger than 14 years old and trauma victims with GCS 13-15 were excluded from the study. Statistical analysis was performed by using Statistical Analysis Software Version 9.2. Statistical tests performed included Chi-square tests. A p-value less than 0.05 was considered statistically significant. RESULTS: There were 303,435 blunt trauma patients, 8731 (2.9%) of them with GCS of 3-12 that including 6351 (72%) patients with GCS of 3-8 and 2380 (28%) patient with GCS of 9-12. In these 8731 patients with GCS of 3-12, 5372 (61.5%) patients had TBI. There were total 1404 unstable patients in all the blunt trauma patients with GCS of 3-12, 1256 (89%) patients with GCS 3-8, 148 (11%) patients with GCS 9-12. In the 5095 stable blunt trauma patients with GCS 3-8, 32.4% of them had no TBI. The rate in the 2232 stable blunt trauma patients with GCS 9-12 was 50.1%. In the unstable patients with GCS 3-8, 60.5% of them had TBI, and in subgroup of patients with GCS 9-12, only 37.2% suffered from TBI. CONCLUSION: The utility of a GCS 12 and less is limited in prediction of brain injury in multiple trauma patients. Significant proportion of trauma victims with low GCS had no TBI and their impaired neurological status is related to severe extra-cranial injuries. The findings of this study showed that using of GCS in initial triage and decision making processes in blunt trauma patients needs to be re-evaluated.

PURPOSE: We evaluated the short-term and long-term outcomes of emergency operations for peptic ulcer (PUD) complications in a period of time in which the need for surgery is infrequent. METHODS: Retrospective review of operated patients (2007-2015) in one medical center. RESULTS: 81 patients were included (8.9 patients/year): 70 (86.4%) male; 11 (13.6%) female. Indications for operation were hemorrhage in 18 (22.2%), perforation in 62 (76.5%) and gastric-outlet obstruction in one (1.2%). Only 16 (19.8%) operations included a procedure to reduce gastric acid secretion. Six (7.4%) patients had a second operation for recurrent or persistent complication. Of these, two had a procedure to reduce gastric acid secretion in their first operation. 16 (19.8%) patients died during the index hospitalization. Three (3.7%) patients were rehospitalized for a PUD complication following 3-24 months. One patient, who had surgery for a second perforation 3 months following the first operation, was treated empirically for Helicobacter Pylori (HP) between the two operations. In comparison to perforation, patients with hemorrhage were older (69.9 ± 20.3 vs. 52.1 ± 19.9 years; p = 0.0015), more commonly had a history of PUD or treatment by nonsteroidal anti-inflammotry drugs (55.6 vs. 19.4%; p = 0.0054), more commonly had a procedure to reduce gastric acid secretion during their index operation (61.1 vs. 6.5%; p < 0.0001), and had a higher mortality (38.9 vs. 14.5%; p = 0.0406). CONCLUSIONS: Mortality is high following surgery for the complications of PUD, moreso in patients undergoing surgery for hemorrhage. Reoperations and repeated hospitalizations for complications are not uncommon, even in patients who have had procedures to reduce gastric acid secretion and HP eradication.

The use of hygroscopic sonographically detectable clips (HSDCs) has dramatically increased during the last years, especially in breast cancer patients who undergo neoadjuvant chemotherapy. The aims of this study are to define the appearance of HSDC sites in histopathological specimens, and to enable pathologists to recognize these sites and differentiate them from other lesions. We examined 124 breast cancer specimens in which the application of HSDCs was documented, 88 breast tissues and 36 lymph nodes, and analyzed the appearance of the clip site in these tissues. The clip site was clearly detected histologically in 79/88 (90%) of the breast specimens and in 29/36 (81%) of lymph node specimens. In most of the specimens, the HSDC site had a specific characteristic appearance of a pseudocyst, lined by layers of epithelioid histiocytes, sometimes with pseudopapillary formation, and with minimal or no fibrosis. This was the appearance in 69 of the breast specimens and in 23 of the lymph node specimens. In other specimens, scarring, scattered foamy macrophages and abundant siderophages were the predominant findings, as usually found in sites of other clips. As non-palpable breast lesions become more frequent, clips play a major role in the treatment of breast cancer, making them an important component of the communication among radiologists, surgeons, pathologists, and oncologists. HSDCs in tissues have a characteristic appearance with an epithelioid component. Pathologists should be able to recognize this finding, differentiate it from other breast lesions and include it in the pathology report.

Enterocutaneous fistulas occur most commonly following surgery. A minority of them is caused by a myriad of other etiologies including infection, malignancy, and radiation. While some fistulas may close spontaneously, most patients will eventually need surgery to resolve this pathology. Successful treatment entails adoption of various methods of treatment aimed at control of sepsis, protection of surrounding skin and soft tissue, control of fistula output, and maintenance of nutrition, with eventual spontaneous or surgical closure of the fistula. The aim of this article is to review the various treatment options in their appropriate context.
ABSTRACT
Autogenous fistulas and in particular radiocephalic fistulas are recommended as the first vascular access for hemodialysis. Unfortunately, the rates of early failure and non-maturation are very high. For more than a decade, brachial plexus block has been proposed as the anesthesia of choice for fistula creation due to its beneficial sympathectomy-like effect, causing vasodilation and attenuation of spasm. Until recently, there was not a single randomized clinical study supporting this proposition. Because performing regional anesthesia is time-consuming and requires expertise, many surgeons prefer local or general anesthesia for vascular access surgery. However, in August 2016 a randomized clinical trial was published showing that regional anesthesia significantly reduces early failure and improves primary and functional patency at 3 months compared to local anesthesia. The aging of the dialysis population, with their attendant morbidity and increased risk for general anesthesia, makes it clear that regional anesthesia is the recommended approach for fistula creation. The excess time required for this approach will decrease with increasing expertise along the learning curve, and will be compensated by a reduction in time that would otherwise be needed for new access construction due to failure of fistulas constructed under local anesthesia.

Stent grafts (SGs) are widely used for treatment of failing vascular accesses, fistulas and grafts. The mechanical barrier of the covered stent prevents in-stent stenosis and can be used to effectively correct ruptured vein and aneurysms. Treatment of cannulation zone stenosis with SG can be justified when its use is obligatory, in order to prevent total access loss. Although there are worrying complications attendant on SG insertion and cannulation, including jeopardizing future access creation, most studies report no complications of SG in cannulation zone stenosis. SGs for treatment of arteriovenous graft venous anastomosis stenosis is controversial. Two large randomized trials conclusively demonstrate improved primary patency with SGs at the venous anastomosis of arteriovenous graft at up to two years when compared with percutaneous transluminal angioplasty, sustained for up to 2 years and reducing the number of interventions per patient year. However, the ultimate goal of SG treatment of venous anastomosis stenosis is preventing thrombosis and increasing graft longevity, which was unfortunately not fully achieved.

Sonographically detectable clips were introduced over the last decade. We retrospectively studied the rate and duration of sonographically detectable clip detectability in patients with breast cancer who had sonographically detectable clips inserted over a 2-year period. Nine of 26 patients had neoadjuvant chemotherapy, with all clips remaining detectable 140 to 187 days after insertion. Six of the 9 had intraoperative sonographic localization, with 1 reoperation (17%). Eleven additional patients with nonpalpable tumors and sonographically detectable clips had intraoperative sonographic localization with 1 reoperation (9%). In 1 patient, a sonographically detectable clip enabled intraoperative identification of a suspicious lymph node. There were no complications or clip migration. Sonographically detectable clips are helpful in breast cancer surgery with and without neoadjuvant chemotherapy, remaining detectable for many months and often averting preoperative localization and scheduling difficulties.

PURPOSE: Population screening of three common BRCA1/BRCA2 mutations in Ashkenazi Jews (AJ) apparently fulfills screening criteria. We compared streamlined BRCA screening via self-referral with proactive recruitment in medical settings. METHODS: Unaffected AJ, age ≥25 years without known familial mutations, were either self-referred or recruiter-enrolled. Before testing, participants received written information and self-reported family history (FH). After testing, both non-carriers with significant FH and carriers received in-person genetic counseling. Psychosocial questionnaires were self-administered 1 week and 6 months after enrollment. RESULTS: Of 1,771 participants, 58% were recruiter-enrolled and 42% were self-referred. Screening uptake was 67%. Recruited enrollees were older (mean age 54 vs. 48, P < 0.001) and had less suggestive FH (23 vs. 33%, P < 0.001). Of 32 (1.8%) carriers identified, 40% had no significant FH. Post-test counseling compliance was 100% for carriers and 89% for non-carrier women with FH. All groups expressed high satisfaction (>90%). At 6 months, carriers had significantly increased distress and anxiety, greater knowledge, and similar satisfaction; 90% of participants would recommend general AJ BRCA screening. CONCLUSION: Streamlined BRCA screening results in high uptake, very high satisfaction, and no excess psychosocial harm. Proactive recruitment captured older women less selected for FH. Further research is necessary to target younger women and assess other populations.Genet Med advance online publication 08 December 2016.
