Purpose:
Laparoscopic proximal gastrectomy (LPG) has been a standard surgery for early gastric cancer in the upper third of the stomach and large esophagogastric junction gastrointestinal stromal tumor. However, how to reconstruct the stomach after LPG is still debated. This study aimed to evaluate the results of LPG with double-flap reconstruction.

Methods:
A retrospective study was performed with 14 patients undergoing LPG with double-flap reconstruction for early gastric cancer or large tumors in the upper third of the stomach from 2018 to 2021. We evaluated postoperative complications, gastroesophageal reflux and the gastric remnant’s function using endoscopy in accordance with the Los Angeles and Residue-Gastritis-Bile classifications, and patients’ quality of life by the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire.

Results:
Median age was 54 years and 10 patients were male. There were 7 patients with gastrointestinal stromal tumor, 4 with leiomyoma and 3 with early-stage adenocarcinoma. No patient had major complications or required conversion to open surgery. During a median follow-up period of 24.6 months, 1 patient had late anastomotic stricture, 2 had metastasis, and 1 died. Endoscopic evaluation at 6 and 12 months showed good function of the gastric remnant in most patients. Patients’ quality of life improved over time: mean GSRS score was 26.9±12.6, 20.3±7.2, and 18.8±4.2 at 6, 12, and 24 months, respectively.

Conclusions:
LPG with double-flap reconstruction is feasible and safe for early gastric cancer or large tumors in the upper third of the stomach. The long-term functional outcomes and patients’ quality of life were acceptable.
Factors Influencing Suture Difficulty of T-tube Fixation and Closure in Laparoscopic Common Bile Duct Exploration
Authors: Wang Lei , Hou Hui , Zhou Dachen , He Liang , Yu Zongfan 
Published: May 2022

Background:
Suture under the laparoscopy was considered as one of the most difficult and time-consuming tasks in laparoscopic common bile duct (CBD) exploration. Difficult suturing can lead to prolonged suturing time and decreased suturing quality. The aim of this study was to identify preoperative factors associated with the difficulty of T-tube suture following laparoscopic bile duct exploration.

Materials and Methods:
Retrospective analysis of consecutive patients who experienced successful laparoscopic CBD exploration with T-tube drainage were collected. Perioperative outcomes and short-term and long-term complications were recorded. Associations of the average suture time per stitch with preoperative demographic data and laboratory tests in patients were analyzed.

Results:
A total of 106 cases (46 males and 60 females) were included in this study. The average suture time per stitch was between 3 and 7.5 minutes with a median of 4.5 minutes (4, 5). There were no biliary leakage and other T-tube-related complications in all patients during follow-up. Spearman correlation analysis revealed that biliary tract reoperation (r=0.384, P<0.0001) and a higher body mass index (r=0.486, P<0.0001) were positively correlated with the average suture time per stitch, while there was no association between the average suture time per stitch and other preoperative demographic data and preoperative blood parameters, including CBD diameter, age, sex, operative time, preoperative white cell count, alanine transaminase, total bilirubin, and gamma-glutamyl transpeptidase.

Conclusions:
We have identified 2 preoperative variables (biliary tract reoperation and a higher body mass index) that were positively associated with the suture difficulty under laparoscopy. An adequately powered prospective multicentre study is needed to validate our findings.
Retention Time of Endoscopic Nasobiliary Drainage and Symptomatic Choledocholithiasis Recurrence After Endoscopic Retrograde Cholangiopancreatography: A Single-center, Retrospective Study in Fuyang, China
Authors: Wu Jinqing , Wang Guizhou 
Published: May 2022

Background and Objectives:
Endoscopic nasobiliary drainage (ENBD) is usually retained for several days after choledocholithiasis is removed by endoscopic retrograde cholangiopancreatography (ERCP). ENBD placement provides reliable biliary drainage and perfusion, prevents pancreatitis, and allows for cholangiography. However, it has not been established whether retention time of ENBD is associated with symptomatic choledocholithiasis recurrence after ERCP. For this reason, we estimated the effect of ENBD retention time on symptomatic choledocholithiasis recurrence after ERCP.

Patients and Methods:
A total of 1016 patients in whom choledocholithiasis had been diagnosed and ERCP had been performed to remove choledocholithiasis were retrospectively reviewed. Their ENBD retention time was 4.01±1.53 days. They were divided into group 1 (n=570) and group 2 (n=446) according to the mean value. Cumulative recurrence rates of symptomatic choledocholithiasis after ERCP were compared between the 2 groups. To identify independent factors associated with symptomatic choledocholithiasis recurrence, various likely predictors associated with the intergroup differences were also recorded.

Results:
There were 570 patients with ENBD retention time ≤4.01 days (group 1) and 446 patients with ENBD retention time >4.01 days (group 2). No statistically significant differences between the 2 groups were evident in terms of demographic factors and laboratory results, except for amylase (AMY) and opening diet time after ERCP. The median (interquartile range) follow-up was 23.7 (14.6, 32.13) months (range: 4.3 to 70 mo) in group 1 and 23.7 (14.6, 31.2) months (range: 4.2 to 69.4 mo) in group 2 (P=0.762). The cumulative recurrence rates of symptomatic choledocholithiasis were 3.1% (2.5% vs. 3.8%) at month 20, 6.7% (5.1% vs. 8.7%) at month 40, and 8.2% (6.7% vs. 10.1%) at month 60 for groups 1 and 2, respectively (P=0.048). By multivariate analysis, being in group 1 reduced symptomatic choledocholithiasis recurrence, with a hazard ratio of 0.641 (95% confidence interval: 0.416-0.987, P=0.044).

Conclusions:
This preliminary study showed that symptomatic choledocholithiasis recurrence may be associated with ENBD retention time after ERCP, particularly for duration of ENBD more than 4.01 days.
The Omental Plug: A Novel Management Approach of Concomitant Ventral Hernias During Bariatric Surgery
Authors: Portela Ray , Mehta Kabir , Vahibe Ahmet , McKenzie Travis , Kendrick Michael , Ghanem Omar M. 
Published: May 2022

Background:
Severe obesity leads to a higher incidence of ventral hernias, thus complicating up to 8% of bariatric procedures. The optimal management of these hernias continues to be a controversial topic. We present our novel approach of utilizing an omental plug for concomitant ventral hernia management during metabolic surgery.

Methods:
To prevent early bowel incarceration and obstruction during bariatric surgery, we sutured the omentum circumferentially to the edges of the hernia defect and to the hernia sac itself with absorbable suture.

Results:
Four patients were managed with this novel omental plug technique. All patients were female. The mean age was 53 years (range 39 to 68 y), the mean body-mass index was 54.75 kg/m2 (range 49 to 59 kg/m2), and the mean follow-up was 4.6 months (range 1.5 to 6.5 mo). There were no hernia-related complications through the follow-up period.

Conclusion:
The omental plug technique is a feasible, inexpensive, and safe alternative for ventral hernias with the potential prevention of bowel incarceration during bariatric surgery. This approach allows deferring the definitive hernia repair for a later stage.
Evidence-based principles of time, triage and treatment: Refining the initial medical response to massive casualty incidents
Authors: Shackelford Stacy A. , Remley Michael A. , Keenan Sean , Kotwal Russ S. , Baker Jay B. , Gurney Jennifer , Rush Stephen , Friedrichs Paul 
Published: May 2022

BACKGROUND
The overall approach to massive casualty triage has changed little in the past 200 years. As the military and civilian organizations prepare for the possibility of future large-scale combat operations, terrorist attacks and natural disasters, potentially involving hundreds or even thousands of casualties, a modified approach is needed to conduct effective triage, initiate treatment, and save as many lives as possible.

METHODS
Military experience and review of analyses from the Department of Defense Trauma Registry are combined to introduce new concepts in triage and initial casualty management.

RESULTS
The classification of the scale of massive casualty (MASCAL) incidents, timeline of life-saving interventions, immediate first pass actions prior to formal triage decisions during the first hour after injury, simplification of triage decisions, and the understanding that ultra-MASCAL will primarily require casualty movement and survival needs with few prehospital life-saving medical interventions are discussed.

CONCLUSION
Self aid, bystander, and first responder interventions are paramount and should be trained and planned extensively. Military and disaster planning should not only train these concepts, but should seek innovations to extend the timelines of effectiveness and to deliver novel capabilities within the timelines to the greatest extent possible.
The new face of war: Craniofacial injuries from Operation Inherent Resolve
Authors: Neubauer Daniel C. , Camacho Macario , O’Reilly Eamon B. , Brice Matthew , Gurney Jennifer M. , Martin Matthew J. 
Published: May 2022

BACKGROUND
During the last 20 years of conflict in the Middle East, improvements in body armor and the use of improvised explosive devices have resulted in an increased incidence of complex craniofacial trauma (CFT). Currently, CFT comprises up to 40% of all casualties. We present new data from the recent conflict in Iraq and Syria during Operation Inherent Resolve.

METHODS
Data were collected for patients treated at role 1, role 2, and role 3 facilities in Iraq and Syria over a 1-year period. During this time, a specialized head & neck surgical augmentation team was deployed and colocated with the central role 3 facility. Data included for this cross-sectional study are as follows: injury type and mechanism, triage category, initial managing facility and subsequent levels of care, and procedures performed.

RESULTS
Ninety-six patients sustained CFT over the study period. The most common injuries were soft tissue (57%), followed by cranial (44%) and orbital/facial (31%). Associated truncal and/or extremity injuries were seen in 46 patients (48%). There were marked differences in incidence and pattern of injuries between mechanisms (all p < 0.05). While improvised explosive devices had the highest rate of cranial and truncal injuries, gunshot wounds and blunt mechanisms had higher incidences of orbital/facial and neck injuries. Overall, 45% required operative interventions including complex facial reconstruction, craniotomy, and open globe repair. Mortality was 6% with 83% due to associated severe brain injury. Most patients were local nationals (70%) who required discharge or transfer to the local health care system.

CONCLUSION
Complex craniofacial trauma is increasingly seen by deployed surgeons, regardless of subspecialty training or location. Deployment of a centrally located head and neck team greatly enhances the capabilities for forward deployed management of CFT, with excellent outcomes for both US and local national patients.

Military-civilian partnerships and the clinical readiness mission: A preliminary study from the Military Health System and the American College of Surgeons
Authors: Grabo Daniel J. , Gurney Jennifer M. , Parascandola Lowell , Knudson M. Margaret 
Published: May 2022

BACKGROUND
The Blue Book, published in conjunction with the Military Health System Strategic Partnership with the American College of Surgeons, serves as a reference manual for institutions wishing to establish a military-civilian partnership (MCP). To evaluate the applicability of the criteria contained in the Blue Book, we created a survey to be distributed to MCP military surgeons and their civilian host champions.

METHODS
E-mail surveys were sent to MCP military surgeons and civilian host champions. Military surgeons were queried about basic demographic information and aspects of the MCP including type, duration of assignment, onboarding, malpractice coverage, and billing for services. We gathered information on the role of military surgeons at the MCP, workload information, and trauma cases. The civilian host champions survey focused on institutional activities including trauma surgical volume, clinical and educational opportunities for the military surgeons, and exposure to research. Military-civilian partnership military surgeons and civilian host champions were questioned on program attributes: administrative support, budget, and profile of the program within the institution.

RESULTS
Ten MCP military surgeons and 7 host champions completed surveys. The majority of military surgeons were assigned to the MCP for a 3-year instructor role (90%), and most were trauma surgeons (80%). Clinical activities for the military surgeon were where 60% spent ≥13 weeks annually on trauma. Military surgeons identified host program support in academic growth, deployment preparation, and sense of value at the MCP as positive attributes. Civilian host champions unanimously reported that exposure to research, opportunities to lead trauma teams, dedicated intensive care unit time, and patient volume were positive program attributes.

CONCLUSION
This preliminary survey demonstrates that the criteria put forth in the Blue Book align with experiences of MCP military surgeons and host champions. Continued development of this survey and others like it may be useful in the MCP program selection and evaluation process.

The efficacy of weight-based enoxaparin dosing for venous thromboembolism prophylaxis in trauma patients: A systematic review and meta-analysis
Authors: Ebeid Annelize , Cole Elaine , Stallwood-Hall Catrin 
Published: May 2022

BACKGROUND
Trauma patients are at high risk of developing venous thromboembolism (VTE), and standard dosing enoxaparin regimens may be inadequate for prophylaxis. This meta-analysis was performed to clarify the efficacy of alternative dosing regimens for VTE prophylaxis in this high-risk group. The objective of this systematic review was to review the evidence regarding weight-based dosing of enoxaparin for VTE prophylaxis in trauma patients.

METHODS
A systematic database search was undertaken for studies comparing standard versus weight-based dosing of enoxaparin for VTE prophylaxis in adult trauma patients, 18 years or older. The primary outcome was the achievement of anti–factor Xa (AFXa) levels within the prophylactic range. Secondary outcomes included subprophylactic AFXa levels, supraprophylactic AFXa levels, VTE incidence, and bleeding events. Meta-analysis was conducted using both fixed- and random-effects models, and presented as odds ratios, risk ratios (RRs), and risk differences (RDs) with 95% confidence intervals (CIs).

RESULTS
Four cohort studies were eligible for inclusion. Compared with standard dosing, weight-based enoxaparin prophylaxis dosing was associated with increased odds of prophylactic AFXa levels (odds ratio, 5.85; 95% CI, 3.02–11.30; p < 0.00001) and reduced risk of subprophylactic AFXa levels (RR, 3.97; 95% CI, 3.02–5.22; p < 0.00001). Standard dosing was associated with a reduced risk of supratherapeutic AFXa levels (RR, 0.23; 95% CI, 0.11–0.50; p = 0.0002), but this was not associated with a difference in risk of bleeding events (RD, −0.00; 95% CI, −0.02 to 0.01; p = 0.55). There was no statistical difference in incidence VTE between the two groups (RD, 0.01; 95% CI, −0.02 to 0.03; p = 0.64).

CONCLUSION
Compared with standard dosing, weight-based enoxaparin dosing regimens are associated with increased odds of prophylactic range AFXa levels. Further investigation is required to determine if this translates into improved VTE prophylaxis and reduced VTE incidence.

ABSTRACTDespite early interest, the evidence linking fatty acids to cardiovascular diseases remains controversial. We used Mendelian randomization to explore the involvement of polyunsaturated (PUFA) and monounsaturated (MUFA) fatty acids biosynthesis in the aetiology of several cardiovascular disease endpoints in up to 1,153,768 European and 212,453 East Asian ancestry individuals. As instruments, we selected single nucleotide polymorphisms (SNP) mapping to genes with well-known roles in PUFA (i.e. FADS1/2 and ELOVL2) and MUFA (i.e. SCD) biosynthesis. Our findings suggest that higher PUFA biosynthesis rate (proxied by rs174576 near FADS1/2) is related to higher odds of multiple cardiovascular diseases, particularly ischemic stroke, peripheral artery disease and venous thromboembolism, whereas higher MUFA biosynthesis rate (proxied by rs603424 near SCD) is related to lower odds of coronary artery disease among Europeans. Results were unclear for East Asians as most effect estimates were imprecise. By triangulating multiple approaches (i.e. uni-/multi-variable Mendelian randomization, a phenome-wide scan, genetic colocalization and within-sibling analyses), our results are compatible with higher low- density lipoprotein (LDL)-cholesterol (and possibly glucose) being a downstream effect of higher PUFA biosynthesis rate. Our findings indicate that genetically-determined PUFA and MUFA biosynthesis are involved in the aetiology of cardiovascular diseases and suggest LDL-cholesterol as a potential mediating trait between PUFA biosynthesis and cardiovascular diseases risk.
Making Biomedical Research Software FAIR: Actionable Step-by-step Guidelines with a User-support Tool
Authors: Patel Bhavesh , Soundarajan Sanjay , Ménager Hervé , Hu Zicheng 
Published: May 2022

AbstractFindable, Accessible, Interoperable, and Reusable (FAIR) guiding principles tailored for research software have been proposed by the FAIR for Research Software (FAIR4RS) Working Group. They provide a foundation for optimizing the reuse of research software. The FAIR4RS principles are, however, aspirational and do not provide practical instructions to the researchers. To fill this gap, we propose in this work the first actionable step-by-step guidelines for biomedical researchers to make their research software compliant with the FAIR4RS principles. We designate them as the FAIR Biomedical Research Software (FAIR-BioRS) guidelines. Our process for developing these guidelines, presented here, is based on an in-depth study of the FAIR4RS principles and a thorough review of current practices in the field. To support researchers, we have also developed a workflow that streamlines the process of implementing these guidelines. This workflow is incorporated in FAIRshare, a free and open-source software application aimed at simplifying the curation and sharing of FAIR biomedical data and software through user-friendly interfaces and automation. Details about this tool are also presented.

AbstractGuaranteeing durability, provenance, accessibility, and trust in open datasets can be challenging for researchers and organizations that rely on public repositories of data critical to epidemiology and other health analytics. Not only are the required repositories sometimes difficult to locate, and nearly always require conversion into a compatible format, they may move or change unpredictably. Any single change of the rules in one repository can hinder updating of a public dashboard reliant on pulling data from external sources. These concerns are particularly challenging at the international level, because systems aimed at harmonizing health and related data are typically dictated by national governments to serve their individual needs. In this paper, we introduce a comprehensive public health data platform, the EpiGraphHub, that aims to provide a single interoperable repository for open health and related data, curated by the international research community, which allows secure local integration of sensitive databases whilst facilitating the development of data-driven applications and reports for decision-makers. The platform development is co-funded by the World Health Organization and is fully open-source to maximize its value for large-scale public health studies.

ABSTRACTBackgroundMost new SARS-CoV-2 epidemics in France occurred following importation from abroad of emerging viral variants. Currently, the control of such risk of new variant importation is based on the negativity of a screening test (PCR or antigenic) and on an up-to-date vaccine status, such as International Air Transport Association travel pass.MethodsWastewater of 2 planes arriving in Marseille (France) from Addis-Ababa (Ethiopia) on December 2021 were i) tested by RT-PCR for SARS-CoV2 detection, and variants screening; these tests were carried out between landing and custom clearance, ii)sequenced by MiSeq Illumina.Antigenic tests and sequencing by NovaSeq were carried out on respiratory samples collected from the 56 passengers of the second flight.ResultsSARS-CoV-2 RNA suspected of being from the Omicron BA.1 variant was detected on the aircraft’s wastewater.,SARS-CoV2 RNA was detected for 11 (20%) passengers and the Omicron BA.1 variant was identified.ConclusionOur work shows the efficiency of aircraft wastewater testing to detect SARS-CoV-2 cases among travelers and identify the viral genotype. It also highlights the low performance for incoming flights from outside Europe to France of the current filter strategy that combines requirement for a vaccine pass and a negative testing before boarding.
