Racial differences in parent response to COVID schooling policies.

This paper examines whether school COVID-19 policies influenced enrollment differently by student age and race/ethnicity. Unlike much prior research, we i) analyze enrollments for virtually the entire U.S. public school population for both the 2020-2021 and 2021-2022 school years, ii) compare enrollment trends within districts in order to isolate subgroup heterogeneity from district characteristics, and iii) account for district selection into preferred learning modes. Analyzing data on over 9,000 districts that serve more than 90% of public school students in the United States, we find enrollment responses to COVID policies differed notably. We find that White enrollments declined more than Black, Hispanic, and Asian enrollments in districts that started the 2020-2021 school year virtually, but in districts that started in-person the reverse was true: Non-White enrollments declined more than White enrollments. Moreover, Black, Hispanic, and Asian families responded more than White families to higher COVID-19 death rates in the months preceding the start of the 2021 school year. In 2021-2022, enrollment differences by the previous year's learning mode persisted. Racial/ethnic differences did not vary by whether the district required masking in classrooms. These findings are consistent with the greater risk faced by communities of color during the pandemic and demonstrate an additional source of disparate impact from COVID policies.

Laparoscopic versus robotic inguinal hernia repair: 1- and 2-year outcomes from the RIVAL trial.

INTRODUCTION: Robotic inguinal hernia repair is growing in popularity among general surgeons despite little high-quality evidence supporting short- or long-term advantages over traditional laparoscopic inguinal hernia repair. The original RIVAL trial showed increased operative time, cost, and surgeon frustration for the robotic approach without advantages over laparoscopy. Here we report the 1- and 2-year outcomes of the trial. METHODS: This is a multi-center, patient-blinded, randomized clinical study conducted at six sites from 2016 to 2019, comparing laparoscopic versus robotic transabdominal preperitoneal (TAPP) inguinal hernia repair with follow-up at 1 and 2 years. Outcomes include pain (visual analog scale), neuropathic pain (Leeds assessment of neuropathic symptoms and signs pain scale), wound morbidity, composite hernia recurrence (patient-reported and clinical exam), health-related quality of life (36-item short-form health survey), and physical activity (physical activity assessment tool). RESULTS: Early trial participation included 102 patients; 83 (81%) completed 1-year follow-up (45 laparoscopic vs. 38 robotic) and 77 (75%) completed 2-year follow-up (43 laparoscopic vs. 34 robotic). At 1 and 2 years, pain was similar for both groups. No patients in either treatment arm experienced neuropathic pain. Health-related quality of life and physical activity were similar for both groups at 1 and 2 years. No long-term wound morbidity was seen for either repair type. At 2 years, there was no difference in hernia recurrence (1 laparoscopic vs. 1 robotic; P = 1.0). CONCLUSIONS: Laparoscopic and robotic inguinal hernia repairs have similar long-term outcomes when performed by surgeons with experience in minimally invasive inguinal hernia repairs.

Robotic mesh explantation (RoME): a novel approach for patients with chronic pain following hernia repair.

BACKGROUND: Post-herniorrhaphy pain is common with an estimated 8-10% incidence of mesh-related complications, requiring mesh explantation in up to 6% of cases, most commonly after inguinal hernia repairs. Reoperation for mesh explantation poses a surgical challenge due to adhesions, scarring and mesh incorporation to the surrounding tissues. Robotic technology provides a versatile platform for enhanced exposure to tackle these complex cases. We aim to share our experience with a novel robotic approach to address these complex cases. METHODS: A descriptive, retrospective analysis of patients undergoing a robotic mesh explantation (RoME) for mesh-related chronic pain, or recurrent ventral hernia by two surgeons between the period of March 2016 and January of 2020. The patients were evaluated for resolution of mesh related abdominal pain as well as early post-operative complications. RoME was performed with concomitant hernia repair in cases of recurrences. RESULTS: Twenty-nine patients underwent a robotic mesh explantation (RoME) for mesh-related chronic pain, or recurrent ventral hernia between March 2016 and January of 2020. Nineteen patients (65.5%) had a prior inguinal hernia repair and 10 patients (34.5%) had a prior ventral hernia repair. Indications for mesh removal included chronic pain with or without hernia recurrence. Seventeen patients (58.6%) reported improvement or resolution of pain postoperatively (63% with a prior inguinal hernia repair and 50% of patients with a prior ventral hernia repair). Five patients (17.2%) required mesh reinforcement after explantation. Nineteen patients (65.5%) underwent mesh explantation with primary fascial closure or no mesh reinforcement. The mean follow-up was 36.4 days. The most common postoperative complication was seroma formation (6.8%), with one reported recurrence (3.4%). CONCLUSION: Robotic mesh explantation in challenging cases due to the effect of chronic scarring, adhesions and mesh incorporation to the surrounding tissues is safe and provides an advantageous platform for concomitant hernia repair in these complex cases.

Closed Facebook groups and COVID-19: an evaluation of utilization prior to and during the pandemic.

BACKGROUND: Surgical education was limited during the COVID-19 pandemic due to redeployment, limited clinical activity, and cancelation of elective procedures and educational conferences. Closed Facebook groups became a tool for surgical education while upholding social distancing guidelines. We aim to evaluate the use of Online Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) closed Facebook groups, during and prior to the COVID-19 pandemic. METHODS: Institutional Review Board evaluation and written consent was not indicated as the data does not pertain to any human subjects. Data files pertaining to new membership activity, posts, comments and reactions of eight closed Facebook groups. The pandemic group was defined as March 19th to April 30, 2020. The pre-pandemic group was defined as February 6th, to March 18th, 2020. The percentage increase of new memberships, posts, comments and reactions were calculated for each period. A two-tailed t-test, using a significance level of 0.05 was used to evaluate significance. RESULTS: A statistically significant increase in membership during the pandemic period was noted for each group. In regards to posts, the Flex Endo, Acute Care, Colorectal, Foregut, and Bariatric groups were noted to have a statistically significant increase in the pandemic period. Colorectal and Bariatric groups were the only two groups that were noted to have a significant increase in comments in the pandemic period. For reactions, Flex Endo, Colorectal, Foregut, and Bariatric groups were noted to have experienced a significant increase during the pandemic. CONCLUSIONS: The COVID-19 pandemic halted surgical education at all levels. The membership and utilization of closed Facebook groups increased significantly in many instances, demonstrating the importance of internet-based surgical education now and into the future. Further development of internet-based curriculums is warranted.

Acronyms Use in Abdominal Wall Reconstruction: Introduction to a New Language.

BACKGROUND: The use of acronyms in medicine is widespread, aiming to simplify and condense communication. Online communication in social media platforms seems to enhance the use of acronyms, but their efficiency in message delivery may be negated by their abundance and unfamiliarity, causing more confusion than clarity. We analyzed the use of acronyms in a closed Facebook group dedicated to abdominal wall reconstruction (AWR), as the rapid recent development of this field has resulted in many new acronyms. Our aim was to classify the different acronyms and create a public reference. METHODS: The International Hernia Collaboration, a hernia-related Facebook group, now communicating more than 7500 surgeons from 99 countries, was studied, by extracting acronyms used since its inception in 2012. Acronyms were categorized and interpreted, to create a small dictionary comprised of several tables. RESULTS: Commonly used acronyms were identified, as well as commonly used prefixes that modify the acronyms' meaning. Tables were created, classifying acronyms by their subject: 1.Anatomy2.Diseases and clinical conditions3.Techniques and materials. CONCLUSION: The use of acronyms increased in social media-based communication. Aiming to simplify the language, the inflation of terms may have achieved the opposite, by adding a multitude of unfamiliar and confusing terms. We have created a public reference for AWR-related acronyms. Limiting the liberal creation of new acronyms is recommended, especially in a rapidly changing field as AWR.

Closed Facebook™ groups and CME credit: a new format for continuing medical education.

BACKGROUND: The International Hernia Collaboration (IHC) is a closed Facebook™ group that allows international surgeons to post clinical questions and exchange transparent feedback with the intent to optimize patient outcomes. Despite the educational value of closed FB groups, CME credits have not been available to members. To determine feasibility of and user interest in earning CME credit through social media, the IHC piloted a series of expert lectures followed by an interactive Facebook Live session as a novel pathway offering CME credit. METHODS: Nine monthly lectures and Facebook Live sessions were presented. CME credit was offered for the final seven lectures. Participation in the form of views, comments, and likes was quantified by a Facebook analytics service and an engagement score, defined as [(the number of comments × 2) + (the number of reactions)], was calculated for each lecture and Facebook Live session. CME credit was obtained through a two-question quiz. RESULTS: Of 5400 + Facebook members of the IHC, an average of 1116 (20.4 ± 4.0%) viewed the live session event following each lecture (n = 9 events). The average Facebook engagement score for Facebook Live was 259 ± 75, a significant difference with the average Facebook engagement score on the IHC (40.8) over the same time period (p < 0.001). On average, 16 users [range 8-35, (n = 7 events)] claimed CME credit for each educational series. CONCLUSIONS: Closed Facebook groups can be a useful media to offer educational content and CME credit. The pilot IHC Lecture and Facebook Live series offering CME credit resulted in significantly more engagement amongst its members compared to other posts during the same time period. A small portion of participants qualified for CME credit. Future social media educational series may increase participants qualifying for CME by streamlining the interface to obtain CME credit.

A Society of Gastrointestinal and Endoscopic Surgeons (SAGES) statement on closed social media (Facebook®) groups for clinical education and consultation: issues of informed consent, patient privacy, and surgeon protection.

INTRODUCTION: Closed social media groups (CSMG), including closed Facebook® groups, are online communities providing physicians with platforms to collaborate privately via text, images, videos, and live streaming in real time and optimize patient care. CSMG platforms represent a novel paradigm in online learning and education, so it is imperative to ensure that the public and patients trust the physicians using these platforms. Informed consent is an essential aspect of establishing this trust. With the launch of several of its own CSMG, Society of Gastrointestinal and Endoscopic Surgeons (SAGES) sought to define its position on CSMG platforms and provide an informed consent template for educating and protecting patients, surgeons, and institutions. METHODS: A review of the literature (2012-2018) discussing the informed consent process for posting clinical scenarios, photography, and/or videography on social media was performed. Pertinent articles and exemplary legal counsel-approved CSMG policies and informed consent forms were reviewed by members of the SAGES Facebook® Task Force. RESULTS: Eleven articles and two institutional CSMG policies discussing key components of the informed consent process, including patient transparency and confidentiality, provider-patient partnerships, ethics, and education were included. Using this information and expert opinion, a SAGES-approved statement and informed consent template were formulated. CONCLUSIONS: SAGES endorses the professional use of medical and surgical CSMG platforms for education, patient care optimization, and dissemination of clinical information. Despite the growing use of social media as an integral tool for surgical practice and education, issues of informed consent still exist and remain the responsibility of the physician contributor. Responsible, ethical, and compliant use of CSMG platforms is essential. Surgeons and patients embracing CSMG for quality improvement and optimized outcomes should be legally protected. SAGES foresees the use of this type of platform continuing to grow.

SAGES University MASTERS Program: a structured curriculum for deliberate, lifelong learning.

BACKGROUND: Postgraduate training has been haphazard to date. Surgeons have relied on attendance to annual meetings and multiple choice study guides to demonstrate maintenance of certification and continuing medical education. METHODS: SAGES held a retreat to develop the concept and scope of the Masters Program. Surveys were sent to SAGES members to guide curriculum development and selection of anchoring operations. RESULTS: SAGES has developed an educational curriculum across eight domains (Acute Care, Biliary, Bariatric, Colorectal, Hernia, Foregut, Flex Endoscopy, and Robotic Surgery) incorporating SAGES educational materials and guidelines, social media, coaching and mentoring. CONCLUSIONS: Deliberate, lifelong learning should be a better way to teach and learn.

Next Generation Mesh Fixation Technology for Hernia Repair.

Laparoscopic ventral hernia repair (LVHR) remains a safe, reproducible, and popular method employed by surgeons to repair abdominal wall hernias. Patient selection, operative technique, instrumentation, and implant choice all remain surgeon dependent. Inherent in the technique is the option of using mesh. The decision of where to place the mesh and how to optimally fixate the mesh in the onlay, sublay, or intraabdominal positions also remain surgeon dependent and has been the subject of ongoing debates for the past two decades. In an ongoing effort to develop new methods for securing mesh to minimize pain without increased recurrence rates, novel mesh fasteners and mesh textiles have been developed. With increasing surgeon responsibility to improve value, surgeons should concentrate more on choosing the novel options that not only improve outcomes, but also reduce overall costs. This chapter reviews some of the emerging markets for these technologies.

The use of self-gripping (Progrip™) mesh during laparoscopic total extraperitoneal (TEP) inguinal hernia repair: a prospective feasibility and long-term outcomes study.

BACKGROUND: The use of self-gripping mesh during laparoscopic TEP inguinal hernia repairs may eliminate the need for any additional fixation, and thus reduce post-operative pain without the added concern for mesh migration. Long-term outcomes are not yet prospectively studied in a controlled fashion. METHODS: Under IRB approval, from January 2011-April 2013, 91 hernias were repaired laparoscopically with self-gripping mesh without additional fixation. Patients were followed for at least 1 year. Demographics and intraoperative data (defect location, size, and mesh deployment time) are recorded. VAS is used in the recovery room (RR) to score pain, and the Carolinas Comfort Scale ™ (CCS), a validated 0-5 pain/quality of life (QoL) score where a mean score of >1.0 means symptomatic pain, is employed at 2 weeks and at 1 year. Morbidities, narcotic usage, days to full activity and return to work, and CCS scores are reported. RESULTS: Sixty two patients, with 91 hernias repaired with self-gripping mesh, completed follow-up at a mean time period of 14.8 months. Seventeen hernias were direct defects (average size 3.0 cm). Mesh deployment time was 193.7 s. RR pain was 1.1/10 using a VAS. Total average oxycodone/acetaminophen (5 mg/325 mg) usage = 5.0 tablets, days to full activity was 1.6, and return to work was 4.2 days. Thirteen small asymptomatic seromas were palpated without any recurrences or groin tenderness, and all seromas resolved by the 6 month visit. Transient testis discomfort was reported in five patients. Urinary retention was 3.2%. Mean CCS™ scores at the first visit for groin pain laying, bending, sitting, walking, and step-climbing were 0.2, 0.5, 0.4, 0.3, and 0.3, respectively. At the first post op visit, 4.8% had symptomatic pain (CCS > 1). At 14.8 months, no patients reported symptomatic pain with CCS scores for all 62 patients averaging 0.02, (range 0-0.43). There are no recurrences thus far. CONCLUSIONS: Self-gripping mesh can be safely used during laparoscopic TEP inguinal hernia repairs; our cohort had a rapid recovery, and at the 1-year follow-up visit, there were no recurrences and no patients reported any chronic pain as defined by a CCS™ > 1.

The prepped vaginal canal may be a sterile conduit for ventral hernia mesh insertion: a prospective comparative study.

BACKGROUND: Although still experimental, natural orifice translumenal endoscopic surgery (NOTES) aims to use the natural orifices for intraabdominal surgery. Pure transvaginal umbilical hernia repair has been reported. However, mesh protection devices were used to minimize mesh contamination during mesh insertion. The authors believe that before widespread implementation of this technique, more foundational research is indicated to establish the sterility of hernia mesh insertion through this route. This prospective study aimed to compare transvaginal ventral hernia mesh insertion sterility with laparoscopic trocar-site insertion sterility to establish baseline data to help promote the safety of NOTES tranvaginal hernia repair. METHODS: This was a prospective descriptive study (Canadian Task Force classification 2A). With institutional review board approval, 10 patients undergoing laparoscopic surgery for benign gynecologic disease were enrolled in the study. Atrium Prolite mesh (polypropylene monofilament) was inserted into the vagina before and after standard surgical preparation with 10 % povidone­iodine. As a control, mesh also was inserted through a prepped laparoscopic port site. The mesh was cultured for bacterial, fungal, and viral contamination. All patients received standard infection prophylaxis that included preoperative intravenous cefazolin and metronidazole. RESULTS: The unprepped vaginal canal was cultured and demonstrated normal multiorganism vaginal flora in all 10 cases. Of the 10 skin incision mesh samples, 3 (30 %) grew bacteria, including Staphylococcus lugdunensis, a potentially pathogenic organism. In contrast, none of the prepped vaginal mesh specimens yielded any growth of microorganisms or potential pathogens. CONCLUSIONS: This study showed that a surgically prepped vaginal canal can be a sterile conduit for insertion of polypropylene mesh for transvaginal ventral hernia repair without the use of additional mesh protection. Surprisingly, the prepped vaginal conduit in our patients was more sterile than a prepped skin incision.

The Effects of the Flint water crisis on the educational outcomes of school-age children.

In 2014, the municipal water source in Flint, Michigan was switched, causing lead from aging pipes to leach into the city's drinking water. While lead exposure in Flint children increased modestly on average, some children were exposed to high lead levels. Surveys of Flint residents show the water crisis was also associated with increased levels of stress, anxiety, and depression. We use Michigan's administrative education data and utilize synthetic control methods to examine the impact of the crisis on Flint's school-age children. We find decreases in math achievement and increases in special needs classification, even among children living in homes with copper (rather than lead) water service lines. Low socioeconomic status students and younger students experienced the largest effects on math achievement, and boys experienced the largest effects on special needs classification. Our results point toward the broad negative effects of the crisis on children and suggest that existing estimates may substantially underestimate the overall societal cost of the crisis.

How to do a single-stage perforator based nasolabial flap for reconstruction of early-stage tongue cancer.

Tongue cancers are one of the most common subsites of malignancy in the head and neck, of which the majority are squamous cell carcinoma (SCC). Reconstruction following ablative surgery is challenging because of the role of the tongue in articulation, deglutition and protection of the airway. Microvascular free flaps are the current gold standard of reconstruction but are not feasible in all patients. Local and regional flaps provide a less challenging, faster alternative and may be more appropriate in comorbid patients with high anaesthetic risk as well as those with previously irradiated neck and poor vasculature. Nasolabial flaps are not commonly used for tongue reconstruction, requiring a two-staged procedure to allow division of the pedicle. We submit a modification of nasolabial flap as an inferiorly based, islanded perforator flap. This allows for single-stage reconstruction of tongue and floor of the mouth defects following resection of early-stage tongue cancers.

Patient Referrals for Hernia Consultations through the International Hernia Collaboration (IHC) Online Social Media Platform.

Social media platforms are becoming more ubiquitous in surgery with a mission to bring surgeons closer together through education and learning. The purpose of this project is to evaluate the social media posts relating to referral of patients through one of the online social media platforms. The International Hernia Collaboration closed Facebook site was queried with terms relating to referrals and descriptive statistics generated. There were a total of 36 posts relating to surgical referrals between October 2014 and January 2021. Posts were from 32 different surgeons and included 30 different locations throughout the United States. An online social media platform is a viable way to refer patients throughout the United States and abroad. Further study is needed to evaluate the role of social media for surgical referrals and its impact on patient care.

The Impact of Research Grant Funding on Scientific Productivity.

In this paper, we estimate the impact of receiving an NIH grant on subsequent publications and citations. Our sample consists of all applications (unsuccessful as well as successful) to the NIH from 1980 to 2000 for standard research grants (R01s). Both OLS and IV estimates show that receipt of an NIH research grant (worth roughly $1.7 million) leads to only one additional publication over the next five years, which corresponds to a 7 percent increase. The limited impact of NIH grants is consistent with a model in which the market for research funding is competitive, so that the loss of an NIH grant simply causes researchers to shift to another source of funding.

The Impact of NIH Postdoctoral Training Grants on Scientific Productivity.

In this paper, we estimate the impact of receiving an NIH postdoctoral training grant on subsequent publications and citations. Our sample consists of all applications for NIH postdoctoral training grants (unsuccessful as well as successful) from 1980 to 2000. Both ordinary least squares and regression discontinuity estimates show that receipt of an NIH postdoctoral fellowship leads to about one additional publication over the next five years, which reflects a 20 percent increase in research productivity.
