BSW 2020 Light Presenter instructions

Preparing Your Pre-recorded Virtual Presentation


Dear BSW 2020 LIGHT Speakers,

On behalf of the RBSS Organizing Committee, we would like to thank you for your patience and understanding during this time of transition to a virtual conference.

This year, for the virtual congress, we decided to pre-record the oral presentations to avoid technical problems during the live congress. These pre-recorded videos will be streamed on the congress platform at your scheduled slot. We will ask you to be present ‘online’ on the platform during your pre-recorded video presentation, as to be able to respond possible questions by the public.

As the date of the BSW 2020 congress is approaching, we have planned to schedule the recording of oral presentations from 2 November until 6 November. You will need to select a time slot to establish a contact moment on the conference platform for the recording of your oral presentation (see below). Attached are the official preparation instructions for all presentations.


Powerpoint instructions and designated presentation durations

As such, you can begin to prepare your presentation in Powerpoint, which will be presented on your own computer during the recording session. You can use your own template, preferably in a 16:9 configuration.  See for instructions on how to resize your powerpoint or enable custom size settings for your poster. Please take into account the designated time for your presentation:

  • Free paper presentation: online captured video presentation of maximum 6 min oral presentation followed by a live Q/A session right after your presentation (max 2min).

  • E-Poster: online captured video presentation of maximum 2 min oral ‘bullet’ presentation + your e-Poster, which both will be made available in the content library of the conference platform. Presentation powerpoint: 16:9 format; e-Poster format: landscape orientation, A0 size (84,1 x 118,9 cm), to be uploaded as a pdf file. File upload will be made available during the video recording process.
  • BAST trainer trainee presentation: online captured video presentation of maximum 8 min oral presentation. Please include 2 multiple choice question slides at the end of the presentation. Both questions will then be used for polling the attending public during the 4 minutes discussion.

Please use the logo of the conference on your slides or poster: download the small banner or the large logo (use your right mouse click > 'Save image' as or 'Copy image').


Let us help you to record your presentation in advance!

For the assisted video recording, please reserve your preferred time slot  in the CALENDAR on . Please mention in the Name field box directly the email address on which the technical agency will be able to contact you.

This calender gives you a choice of 30-minute slots to record your presentation.

The technical agency will provide you a video recording link for the Streamyard-platform, (which looks like this: where you can join the virtual technical booth to present your slides with your webcam and microphone on during the selected time slot. 


A technician will be with you in the virtual recording room during the recording.

The technician will be able to assist with any questions or issues that you might have for the recording session.

Please read and follow the speaker’s instructions kit carefully on how we will capture your presentation; you can find this document here.

Closer to your presentation date, we will send you a connection link for the live session. In the meantime, you can check in which session and at which indicative time you will need to be present during the meeting as a speaker by consulting the conference program on the conference website.

BSW 2020 Faculty: John Alverdy

John C. Alverdy, MD, FACS

Sarah and Harold Lincoln Thompson Professor of Surgery,

University of Chicago, USA



 John Alverdy, MD, FACS, is a leading surgeon-scientist with a focus on the molecular basis of surgical infections and the gut microbiome. Dr. Alverdy is the Sarah and Harold Lincoln Thompson Professor of Surgery and executive vice-chair, department of surgery, University of Chicago, IL. He has served in leadership positions at many national organizations. He was the 2016 president of the Surgical Infection Society. He received the American Surgical Association’s Flance-Karl Award in 2018 for his groundbreaking work in surgical infection pathogenesis and microbiome research.

Dr. Alverdy has for sure traveled a non-conventional - out of the box -  path to become  the renowed scientist he is now . He was a Spanish major as an undergraduate with a minor in biology. His love of language and travel sent him on a path to foreign affairs schools with the intention of becoming a diplomat. He had little interest in becoming a physician except for the fact that his father, a dentist and son of an immigrant, insisted he would go to medical school. In an interview with the ACS bulletin, he recalls the day he spoke with his advisor, who felt that graduate school in biology would be his best bet to successfully compete for admission to an American medical school. Ironically, he had a strong distaste for biology, so being relatively fluent in Spanish, without applying to any American medical schools, he headed off to medical school in Guadalajara, Mexico where he graduated from. After having  spent one year at Loyola University Chicago Stritch School of Medicine, Maywood, IL he completed a surgical residency at Michael Reese Hospital, an aliate of the University of Chicago at the time. He completed a surgical research fellowship at the University of California-San Francisco (UCSF).

His first big discovery was to demonstrate, for the first time, that intestinal bacteria sense host stress, such as what occurs following injury, and then respond with enhanced virulence. At a time when everyone was studying how the host immune system responds to bacteria, he asked, “How do bacteria respond to the host?” and thought that pathogens are present in our patients all the time, so something about surgical injury must trigger them to express virulence, not accepting that serious infections were just a random encounter with a very bad pathogen. He showed that bacteria sense the physiologic stress of surgery by binding soluble compounds released by host tissues that transduce their quorum sensing resulting in virulence activation.

He is a clinician as well, of course. He performs a wide variety of complex minimally invasive and open gastrointestinal surgical procedures with decades of experience in the field. Dr. Alverdy is nationally recognized for introducing several new operations into the field, including minimally invasive pancreatic surgery, bariatric surgery, and surgery for disorders of the foregut including the esophagus and stomach. He is one of the University of Chicago Hospitals’ most accomplished critical care surgeons and serves as the director for the Surgical Treatment of Obesity Program.

Dr. Alverdy accepted to give two lectures during the virtual BSW dedicated to COVID-19:

-      "The evidence about surgical smoke, fumes, aërosol and COVID-19: what are the risks?" during the 'Surgery in times of COVID-19: What are the risks?' session on November 27th 2020

-      “Letter to a young surgeon“ on Friday’s November 27th final plenary session.
