Can preoperative ureteral stent placement help in the intraoperative identification of iatrogenic ureteral injury?

BACKGROUND

The benefits of prophylactic ureteral stent placement during colorectal surgery remain controversial. This study aimed to determine the incidence of ureteral injury in colorectal operations, assess the complications associated with stent usage, and determine whether their use leads to earlier identification and treatment of injury.

METHODS

This was a retrospective study of patients undergoing colorectal abdominal operations between 2015 and 2021. Variables were examined for possible association with ureteral stent placement. The primary study endpoint was ureteral injury identified within 30 days postoperatively.

RESULTS

Of 6481 patients who underwent colorectal surgery, 970 (15%) underwent preoperative ureteral stent placement. The use of stents was significantly associated with a higher American Society of Anesthesiologists classification, wound classification, and longer duration of surgery. A ureteral injury was identified in 28 patients (0.4%). Of these patients, 13 had no stent, and 15 had preoperative stents placed. After propensity matching, stent use was associated with an increased risk of hematuria and urinary tract infection. Ureteral injury was identified intraoperatively in 14 of 28 patients (50.0%) and was not associated with ureteral stent use (P = .45).

CONCLUSION

Iatrogenic ureteral injury was uncommon, whereas preoperative stent placement was relatively frequent. Earlier recognition of iatrogenic ureteral injury is not an expected advantage of preoperative ureteral stent placement.

Caprini guideline indicated venous thromboembolism (VTE) prophylaxis among inpatient surgical patients: are there racial/ethnic differences in practice patterns and outcomes?

BACKGROUND

While racial disparity in surgical mortality due to venous thromboembolism (VTE) has improved, a gap persists. Our study aim was to determine differences in VTE prevention practices and their impact on outcomes among racial surgical cohorts.

METHODS

Elective surgeries performed between 1.1.2016 and 5.31.2021 were included. Racial/ethnic cohorts were propensity-matched 1:1 to non-Hispanic White (NHW) patients, and outcomes were compared using unadjusted logistic regression. Match cohort balance was assessed using absolute standardized mean differences and linear model analysis of variance (ANOVA). Pearson's Chi-square tests evaluated bi-variate associations. Conditional logistic regression to compare outcomes between matched groups. Odds ratios, 95 ​% confidence intervals, and p-values are reported. Analyses were performed using R version 4.1.2 and the R package Matchit.

RESULTS

Non-Hispanic other race (NHOR) (vs. NHW) patients were less likely to receive inpatient prophylaxis (OR 0.86, CI:0.76-0.98). Appropriate prophylaxis resulted in similar VTE for NHB (p ​= ​0.71) and Hispanic (p ​= ​0.06), compared to NHW patients. Inpatient bleeding was higher in Hispanic patients with a higher likelihood of receiving appropriate prophylaxis (OR 1.94, CI:1.16-3.32) and NHOR patients with a lower likelihood (OR 1.90, CI:1.10-3.36) CONCLUSION: Postoperative VTE was similar for minority patients receiving appropriate prophylaxis, compared to NHW patients. Inpatient bleeding was more likely in Hispanic and NHOR patients but may not be related to receiving appropriate prophylaxis. NHOR patients were less likely to receive inpatient thromboprophylaxis.

The emotional support plan: Feasibility trials of a brief, telehealth-based mobile intervention to support coping for autistic adults

LAY ABSTRACT

Autistic adults may have difficulty coping during stressful periods, which could make them more vulnerable to depression and anxiety. We designed the emotional support plan (ESP) to help autistic people find ways to cope in stressful situations. Thirty-six autistic adults created an ESP and answered questions about their opinions of the ESP. Most autistic adults found the ESP to have a positive impact on them and many would recommend the ESP to another person. Feedback from autistic adults suggested ways that we might test the ESP in future studies. Overall, autistic adults in this study found the ESP to be useful and a worthwhile intervention to study more in the future. While more research is clearly needed, we hope that the brief nature of the ESP will make it helpful for autistic people who are trying to handle negative feelings during stressful life events.

A Scoping Review of Otologic Manifestations of Hematologic Malignancies

OBJECTIVE

To examine the otologic and neurotologic symptoms, physical examination findings, and imaging features secondary to hematologic malignancies.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, databases, including PubMed, Scopus, and CINAHL, were searched for articles including patients with otologic manifestations of leukemia, lymphoma and multiple myeloma. Data collected included patient and study demographics, specific hematologic malignancy, timing and classification of otologic symptoms, physical examination findings, imaging features and methods of diagnosis. Pooled descriptive analysis was performed.

RESULTS

Two hundred seventy-two articles, of which 255 (93.8%) were case reports and 17 (6.2%) were case series, reporting on 553 patients were identified. Otologic manifestations were reported on 307 patients with leukemia, 204 patients with lymphoma and 42 patients with multiple myeloma. Hearing loss and unilateral facial palsy were the most common presenting symptoms for 111 reported subjects with leukemia (n = 46, 41.4%; n = 43, 38.7%) and 90 with lymphoma (n = 38, 42.2%; n = 39, 43.3%). Hearing loss and otalgia were the most common presenting symptoms for 21 subjects with multiple myeloma (n = 10, 47.6%; n = 6, 28.6%). Hearing loss and unilateral facial palsy were the most common otologic symptoms indicative of relapse in subjects with leukemia (n = 14, 43.8%) and lymphoma (n = 5, 50%).

CONCLUSION

Hearing loss, facial palsy, and otalgia might be the first indication of a new diagnosis or relapse of leukemia, lymphoma, or multiple myeloma. Clinicians should have a heightened level of suspicion of malignant etiologies of otologic symptoms in patients with current or medical histories of these malignancies.

Tobacco packaging littering behaviours among Australian adults who smoke: findings from cross-sectional and observational studies to inform the implementation of cigarette pack inserts

BACKGROUND

Cigarette pack inserts are small cards that highlight the benefits of quitting and promote use of smoking cessation support. With evidence from Canada that they increase self-efficacy to quit, quit attempts and sustained cessation, inserts are set to be introduced into tobacco packs sold in Australia. Some people have expressed concern that the introduction of inserts may create more litter if incorrectly disposed of on pack-opening.

METHODS

We used a cross-sectional survey to assess self-reported pack-opening location and waste disposal behaviours of people who smoke to determine the potential for littering to occur when tobacco packs are first opened. We also visited a sample of supermarkets, convenience stores and tobacconists located throughout Melbourne, Australia, to discreetly collect observational data regarding pack-opening and waste disposal behaviours at the point of purchase.

RESULTS

Among participants in the cross-sectional study (N=369), the majority reported that they opened their most recent tobacco pack at home (70.9%) where there is little potential for littering, and this proportion was higher among those who smoke daily (78.6%) and men (74.3%). Self-reported behaviours that could result in littering were rare; 1.0% reported that they left tobacco packaging where they believed it would be collected for disposal. Of the 128 individuals observed at the point of purchase across 46 stores, 96.9% did not open the tobacco product immediately after purchase. One incident of littering was observed (0.8%).

CONCLUSION

The introduction of cigarette pack inserts in Australia is unlikely to create a substantial amount of additional litter.

Risk stratified venous thromboembolism prophylaxis in bariatric patients using a Caprini assessment: practice patterns and opportunities for improvement

BACKGROUND

Venous thromboembolism (VTE) is rare after bariatric surgery but is the most common cause of mortality. The use of VTE risk-stratification tools and compliance with practice guidelines remain unclear.

OBJECTIVES

Our objectives were to determine the utilization of risk-stratified VTE prophylaxis and its impact on VTE and bleeding outcomes.

SETTING

Academic hospital system.

METHODS

Roux-en-Y gastric bypass and sleeve gastrectomy (2016-2021) were identified from our electronic health records. Caprini score and VTE prophylaxis regimen were retrospectively determined. VTE prophylaxis consistent with Caprini guidelines was considered appropriate. Outcomes were compared between VTE prophylaxis cohorts. Variables were compared by Kruskal-Wallis test, Pearson χ2 test, and regression models. A P value of <.05 was considered significant.

RESULTS

A total of 1849 bariatric cases were analyzed, including 64% Roux-en-Y gastric bypass and 36% sleeve gastrectomy cases. Of these, 70% and 3.7% received appropriate risk-stratified VTE prophylaxis during hospitalization and at discharge. The mean Caprini score was higher in those without appropriate prophylaxis (8.45 versus 8.04; P = .0004). Inpatient and 30- and 90-day VTE rates were .22%, .47%, and .64%. All discharge VTE events occurred in those not receiving appropriate Caprini risk-stratified VTE prophylaxis. Inpatient and 30- and 90-day bleeding complications were .22%, .23%, and .35%. The likelihood of receiving appropriate prophylaxis varied by hospital site, and receiving appropriate prophylaxis was not associated with increased bleeding risk.

CONCLUSION

Caprini guideline-indicated VTE prophylaxis can be safely used in bariatric surgery patients and may reduce preventable VTE complications without increasing bleeding risk.

Venous Thromboembolism Prophylaxis in Otolaryngologic Patients Using Caprini Assessment

OBJECTIVE

The aim was to determine the utilization of Caprini guideline-indicated venous thromboembolism (VTE) prophylaxis and impact on VTE and bleeding outcomes in otolaryngology (ORL) surgery patients.

METHODS

Elective ORL surgeries performed between 2016 and 2021 were retrospectively identified. Logistic regression models were used to examine the association between patient characteristics and receiving appropriate prophylaxis, inpatient, 30- and 90-day VTE and bleeding events.

RESULTS

A total of 4955 elective ORL surgeries were analyzed. Thirty percent of the inpatient cohort and 2% of the discharged cohort received appropriate risk-stratified VTE prophylaxis. In those who did not receive appropriate prophylaxis, overall inpatient VTE was 3.5-fold higher (0.73% vs. 0.20%, p = 0.015), and all PE occurred in this cohort (0.47% vs. 0.00%, p = 0.005). All 30- and 90-day discharged VTE events occurred in those not receiving appropriate prophylaxis. Inpatient, 30- and 90-day discharged bleeding rates were 2.10%, 0.13%, and 0.33%, respectively. Although inpatient bleeding was significantly higher in those receiving appropriate prophylaxis, all 30- and 90-day post-discharge bleeding events occurred in patients not receiving appropriate prophylaxis. On regression analysis, Caprini score was significantly positively associated with likelihood of receiving appropriate inpatient prophylaxis (odds ratio [OR] 1.05, confidence interval [CI] 1.03-1.07) but was negatively associated in the discharge cohort (OR 0.43, CI 0.36-0.51). Receipt of appropriate prophylaxis was associated with reduced odds of inpatient VTE (OR 0.24, CI 0.06-0.69), but not with risk of bleeding.

CONCLUSION

Although Caprini VTE risk-stratified prophylaxis has a positive impact in reducing inpatient and post-discharge VTE, it must be balanced against the risk of inpatient postoperative bleeding.

Tobacco Constituents, Flavorants, and Paper Permeability of Factory-Made and Roll-Your-Own Cigarettes on the Australian Market

INTRODUCTION

Roll-your-own (RYO) tobacco is a popular choice in Australia, with some people who smoke finding these products more attractive than factory-made cigarettes (FMC). Differences in visual and tactile properties and in the feel and taste of the smoke may contribute to this attractiveness. These differences may be driven by variation in tobacco constituents and wrapping paper permeability. However, to date, there has been no comparison of RYO and FMC products on the Australian market.

AIMS AND METHODS

Chemical constituents, pH, flavorants, and paper permeability were compared in unburned RYO tobacco and tobacco from FMC. RYO and FMC products from matched brands were compared, as were products from the most popular FMC and RYO brands on the Australian market in 2018.

RESULTS

RYO tobacco had higher moisture and humectant content (glycerol and propylene glycol) than FMC tobacco. RYO tobacco also had higher amounts of total and reducing sugars and lower nicotine when comparing the most popular brands. RYO papers were less permeable than FMC papers. Both RYO and FMC tobacco contained many chemicals identified as flavorants, including fourteen with known potential health risks. For most measured constituents and flavorants, RYO tobaccos had more in common with other RYO than FMC, with the commonalities remaining even when matched brands were compared.

CONCLUSIONS

Higher levels of moisture, humectants, and sugars in Australian RYO tobacco compared to FMC may be increasing attractiveness of RYO by reducing the harsh taste of the smoke and increasing the moist feel of the tobacco.

IMPLICATIONS

While price is the main factor driving the use of RYO tobacco, some people who smoke find these products more attractive. This study has shown that Australian RYO tobacco contains higher amounts of glycerol, propylene glycol, and sugars than FMC. These chemicals may be improving the taste of the tobacco, as well as creating a moist feel that is falsely perceived as indicating that the tobacco is "fresh" and "less chemically." Ironically, it may be that higher amounts of some added chemicals in RYO contribute to false perceptions of a more natural and less harmful product.

The impact of measurement on clinical trials: Comparison of preliminary outcomes of a brief mobile intervention for autistic adults using multiple measurement approaches

Initial studies of the emotional safety plan (ESP), a new, brief telehealth and mobile intervention to support autistic adults to cope with periods of distress, have reported feasibility and acceptability (Bal et al., 2023, Autism, 1-13). Herein we report the preliminary clinical outcomes of thirty-six autistic adults who developed a personalized ESP, with a specific interest in comparing "outcomes" demonstrated by different instruments and assessment frequencies in order to inform outcome measurement in future clinical trials. Comparison of pre-intervention baseline to post-monitoring outcome (pre-post) anxiety symptoms (Generalized Anxiety Disorder-7 [GAD-7]) and depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]) revealed medium effect sizes for reduction in symptoms, though, low effect sizes were observed for pre-post Adult Self-report Anxiety and Depressive Problems scales and the Emotion Dysregulation Inventory Reactivity and Dysphoria scales. Weekly assessments showed an initial decrease in GAD-7 anxiety symptoms but no effect on weekly PHQ-9 depressive ratings. Ecological momentary assessment (EMA) data suggested that, when participants reported feeling sad or agitated and used the ESP, reduced negative feelings and increased positive states were reported in subsequent EMA. Perhaps not surprisingly, preliminary outcomes of these feasibility trials differed depending on measure chosen. Implications for the design of clinical trials are discussed.

Briefings in surgical teams: a pilot study of experiences and attitudes

While healthcare should not be compared to other high reliability organisations (HROs), many lessons, attitudes, and transferable practices can be applied and adapted from them to improve patient safety and team morale. Despite briefings improving both patient safety and effective team working, some in healthcare have not valued or actively engaged with them, deeming them to be irrelevant. In this pilot study we explored the experiences of, and attitudes to, briefings using a 10-question Survey Monkey. This was promoted during a human factors session at the 2023 Association of Surgeons in Training Conference (ASiT) and at a large NHS trust. Questions were asked about the number of briefings per day, attitudes, engagement, and respondents' attitudes to them. In total, 109 responses were received. A total of 85% reported at least one briefing on a normal operating day, 65% felt them to be interactive, 67% reported that briefings were led by the most senior surgical team member, and 58% lasted four minutes or more. Eighteen per cent of respondents felt they were of little benefit, and 56% did not routinely de-brief at the end of the day. This study has highlighted variable attitudes to team briefings, with some colleagues still seeing them as a 'tick box' exercise. While culture has changed following the introduction of the WHO checklist, the importance of active engagement and education to improve the delivery and value of effective briefings cannot be overestimated. It is also an opportunity to create a 'safe space' for team members and to confirm zero tolerance for any inappropriate behaviour, including sexual misconduct.

Can counter-advertising dilute marketing effects of alcohol sponsorship of elite sport: A field experiment

AIMS

To test whether showing spectators counter-advertisements exposing alcohol harms alone, or exposing alcohol harms and alcohol sponsorship, before watching an alcohol-sponsored sporting event promotes less favourable post-event attitudes and intentions towards alcohol sponsor brands and alcohol in general.

DESIGN

On-line between-subjects experiment.

SETTING

Australia.

PARTICIPANTS

A sample of Australian adults aged 18-49 years who planned to watch an alcohol-sponsored National Rugby League (NRL) State of Origin series game was recruited through an online panel.

INTERVENTIONS

Participants were randomly assigned to one of three counter-advertising conditions: control (neutral advertisement); counter-advertisement exposing alcohol harms; and counter-advertisement exposing alcohol sponsorship and harms, to view at least four times during the week before watching the alcohol-sponsored sporting event.

MEASUREMENTS

Participants (n = 1932) completed a pre-test questionnaire a week before the sporting event. Within 4 days of watching the sporting event, participants completed post-test measures assessing sponsor brand awareness, attitudes and preferences towards the brand, as well as knowledge, attitudes and intentions for alcohol in general (n = 1075).

FINDINGS

Compared with the control advertisement, the counter-advertisement exposing alcohol sponsorship and harms promoted higher (6-13%) awareness of sponsor brands, less favourable attitudes towards sponsor brands and drinking beer, lower purchase intentions for sponsor brands (Cohen's d = 0.15, 0.31, 0.27, respectively) and perceived less image-based similarity and fit between the sporting event and sponsor brands (Cohen's d = 0.20 and 0.56). Both counter-advertisements promoted lower perceptions of the appropriateness of consuming alcohol while watching sport (Cohen's d = 0.22 and 0.34), higher awareness of alcohol harms (6-34%) and higher intentions (8-13%) to reduce alcohol consumption than the control advertisement.

CONCLUSIONS

At alcohol-sponsored sporting events, counter-advertisements addressing alcohol harms may promote knowledge of harms and intentions to drink less. Counter-advertisements that additionally expose and critique alcohol sponsorship may detract from perceptions of sponsor brand image and intentions to purchase the sponsor's products.

Quadriceps tendon autograft has similar clinical outcomes when compared to hamstring tendon and bone-patellar tendon-bone autografts for revision ACL reconstruction: a systematic review and meta-analysis

PURPOSE

Research regarding revision anterior cruciate ligament reconstruction (RACLR) with quadriceps tendon (QT) autografts is lacking. The purpose of this study was to perform a systematic review and meta-analysis of RACLR with QT and compare its patient outcomes to RACLR with hamstring tendon (HT) and bone-patellar tendon-bone (BTB) autografts.

METHODS

Adhering to PRISMA guidelines, a search for studies using QT in RACLR was performed within PubMed, Scopus, and CINAHL from database date of inception through December 26, 2022. Primary outcomes sought included: failure rate, Lysholm scores, International Knee Documentation Committee (IKDC) scores, IKDC grades, arthrometric knee side-to-side differences (STSD), pivot shift grade, donor site morbidity, return to sport, visual analog scale (VAS) pain scores.

RESULTS

Nine studies were included consisting of 606 RACLR: 349 QT, 169 HT, and 88 BTB. Overall failure rates were 7.6% QT, 13.3% HT, and 8.7% BTB. Mean weighted Lysholm scores were 85.8 ± 3.8 QT, 82.5 ± 3.8 HT and 86.6 ± 4.5 BTB. IKDC average scores were 82.3 ± 1.6 QT, 80.1 ± 1.7 HT, and 81.7 ± 5.5BTB. Combined rates of IKDC A/B grades were 88.4% and 80.0% for QT and HT, respectively. VAS average scores were 0.9 ± 1.1 QT, 1.4 ± 0.2 HT, and 0.7 ± 0.8 for BTB. Side-to-side difference was reported for QT and HT with average values of 1.7 ± 0.6 mm and 2.1 ± 0.5 mm, respectively. Grade 0 or 1 pivot shifts were reported in 96.2% of QT patients and 91.3% of HT. Donor site morbidity, only reported for QT and HT, was 14.6 ± 9.7% and 23.6 ± 14.1%, respectively. QT resulted in a mean Tegner score of 5.9 ± 1.5 versus HT 5.7 ± 1.5. Rate of return to pivoting sports was 38.0% QT, 48.6% HT, and 76.9% BTB. Across all outcomes, there was no significant difference when comparing QT to HT, QT to BTB, and QT compared to HT and BTB combined.

CONCLUSIONS

RACLR with QT yields satisfactory patient reported outcomes, satisfactory improvement in knee laxity, expected return to sport rates, and has an overall 7.6% failure rate. Outcomes are comparative to those of HT and BTB making it an acceptable graft choice for RACLR. Surgeons should consider using QT autograft for RACLR, especially when other autografts are unavailable.

Outcomes in Primary Repair of Truncus Arteriosus with Significant Truncal Valve Insufficiency: A Systematic Review and Meta-analysis

Data regarding the effect of significant TVI on outcomes after truncus arteriosus (TA) repair are limited. The aim of this meta-analysis was to summarize outcomes among patients aged ≤ 24 months undergoing TA repair with at least moderate TVI. A systematic literature search was conducted in PubMed, Scopus, and CINAHL Complete from database inception through June 1, 2022. Studies reporting outcomes of TA repair in patients with moderate or greater TVI were included. Studies reporting outcomes only for patients aged > 24 months were excluded. The primary outcome was overall mortality, and secondary outcomes included early mortality and truncal valve reoperation. Random-effects models were used to estimate pooled effects. Assessment for bias was performed using funnel plots and Egger's tests. Twenty-two single-center observational studies were included for analysis, representing 1,172 patients. Of these, 232 (19.8%) had moderate or greater TVI. Meta-analysis demonstrated a pooled overall mortality of 28.0% after TA repair among patients with significant TVI with a relative risk of 1.70 (95% CI [1.27-2.28], p < 0.001) compared to patients without TVI. Significant TVI was also significantly associated with an increased risk for early mortality (RR 2.04; 95% CI [1.36-3.06], p < 0.001) and truncal valve reoperation (RR 3.90; 95% CI [1.40-10.90], p = 0.010). Moderate or greater TVI before TA repair is associated with an increased risk for mortality and truncal valve reoperation. Management of TVI in patients remains a challenging clinical problem. Further investigation is needed to assess the risk of concomitant truncal valve surgery with TA repair in this population.

Features associated with travel distance for radical cystectomy in Florida: Implications for access to care

INTRODUCTION

Characteristics associated with travel distance for radical cystectomy (RC) remain incompletely defined but are needed to inform efforts to bridge gaps in care. Therefore, we assessed features associated with travel distance for RC in a statewide dataset.

METHODS

We identified RC patients in the Florida Inpatient Discharge dataset from 2013 to 2019. Travel distance was estimated using zip code centroids. The primary outcome was travel >50 miles for RC. Secondary outcomes included inpatient mortality, nonhome discharge, and inpatient complications. U.S. County Health Rankings were included as model covariates. Mixed effects logistic regression models accounting for clustering within hospitals were utilized.

RESULTS

We identified 4,209 patients, of whom 2,284 (54%) traveled <25 miles, 654 (16%) traveled 25 to 50 miles, and 1271 (30%) traveled >50 miles. Patients who traveled >50 miles primarily lived in central and southwest Florida. Following multivariable adjustment, patients traveling >50 miles were less likely to be Hispanic/Latino (odds ratio [OR] 0.35, 95% CI: 0.23-0.51), and more likely to reside in a county with the lowest health behavior (OR 6.48, 95% CI: 3.81-11.2) and lowest socioeconomic (OR 7.63, 95% CI: 5.30-11.1) rankings compared to those traveling <25 miles (all P < 0.01). Travel distance >50 miles was associated with treatment at a high-volume center and significantly lower risks of inpatient mortality, nonhome discharge, and postoperative complications (all P < 0.02).

CONCLUSION

These data identify characteristics of patients and communities in the state of Florida with potentially impaired access to RC care and can be used to guide outreach efforts designed to improve access to care.

Can Risk-Based Thromboprophylaxis Practice Guidelines be Safely Used in Esophagectomy Cases? Experience of an Academic Health System

BACKGROUND

Venous thromboembolism (VTE) occurs in 3-11% of esophagectomy patients and is associated with increased mortality and morbidity. The use of validated VTE risk assessment tools and compliance with recommended practice guidelines remains unclear. In this study, we seek to determine the use of Caprini guideline indicated VTE prophylaxis and its effect on VTE and bleeding complications following esophagectomy.

METHODS

Esophagectomy cases were identified from the Mayo Clinic electronic health records. Caprini score and VTE prophylaxis regimen received were determined retrospectively. VTE prophylaxis was identified as appropriate or inappropriate based on the Caprini score and prophylaxis received preoperative, during hospitalization, and after hospital discharge. Study cohorts were compared by Pearson Chi-square test, Fisher's Exact test, Kruskal-Wallis test, and logistic regression models. Stata/MP 16.1 was used for analysis. Odds ratios and 95% confidence intervals were reported for logistic regression models. A p-value < 0.05 was considered significant.

RESULTS

Four hundred and fifty-six esophagectomy cases were analyzed. The median Caprini score was thirteen. Appropriate prophylaxis resulted in a 6.9-fold reduction in inpatient VTE. All 30- and 90-day post-discharge VTEs occurred in those not receiving Caprini guideline-indicated VTE prophylaxis. Inpatient, 30- and 90-day post-discharge bleeding rates were 7.68%, 0.91%, and 2.11%, respectively; however, bleeding was not increased with receipt of appropriate prophylaxis.

CONCLUSION

In this esophagectomy cohort, Caprini guideline indicated VTE prophylaxis resulted in reduced inpatient VTE events without increasing bleeding complications. Risk-based VTE prevention measures should be considered in this patient cohort known to be at heightened risk for postoperative VTE.

Venous thromboembolism and bleeding after hepatectomy: role and impact of risk adjusted prophylaxis

Venous thromboembolism (VTE) occurs in 2-6% of post-hepatectomy patients and is associated with increased mortality and morbidity. The use of VTE risk assessment models in hepatectomy cases remains unclear. Our study aimed to determine the use and impact of Caprini guideline indicated VTE prophylaxis following hepatectomy. Hepatectomy cases performed during 2016-2021 were included. Caprini score and VTE prophylaxis were determined retroactively, and VTE prophylaxis was categorized as appropriate or inappropriate. The primary outcome was the receipt of appropriate prophylaxis, and secondary outcomes were postoperative VTE and bleeding. Statistical analyses included Fisher Exact test, Kruskal-Wallis, Pearson Chi-Square test, and multivariate regression models. R Statistical software was used for analysis. A p-value < 0.05 or 95% Confidence Interval (CI) excluding 1 was considered significant. A total of 1955 hepatectomy cases were analyzed. Patient demographics were similar between study cohorts. Inpatient, 30- and 90-day VTE rates were 1.28%, 0.56%, and 1.24%, respectively. By Caprini guidelines, 59% and 4.3% received appropriate in-hospital and discharged VTE prophylaxis, respectively. Inpatient VTE (4.5-fold) and mortality (9.5-fold) were lower in patients receiving appropriate prophylaxis. All discharged VTE and mortality occurred in patients not receiving appropriate prophylaxis. Inpatient, 30- and 90-day bleeding rates were 8.4%, 0.62%, and 0.68%, respectively. Appropriate prophylaxis did not increase postoperative bleeding. Increasing Caprini score inversely correlated with receiving appropriate prophylaxis (OR 0.38, CI 0.31-0.46) at discharge, and appropriate prophylaxis did not correlate with bleeding risk (OR 0.79, CI 0.57-1.12). Caprini guideline indicated prophylaxis resulted in reduced VTE complications without increasing bleeding risk.

Caprini assessment utilization and impact on patient safety in gynecologic surgery

PURPOSE

Postoperative venous thromboembolism (VTE) can potentially be associated with significant morbidity, mortality, and healthcare costs. The aim of this study was to determine the utilization of Caprini guideline indicated VTE in elective gynecologic surgery patients and its impact on postoperative VTE and bleeding complications.

METHODS

This was a retrospective cohort study of elective gynecologic surgical procedures performed between January 1, 2016, and May 31, 2021. Two study cohorts were generated: (1) those who received and (2) those who did not receive VTE prophylaxis based on Caprini score risk stratification. Outcome measures were then compared between the study cohorts and included the development of a VTE up to 90-days postoperatively. Secondary outcome measures included postoperative bleeding events.

RESULTS

A total of 5471 patients met inclusion criteria and the incidence of VTE up to 90 days postoperatively was 1.04%. Overall, 29.6% of gynecologic surgery patients received Caprini score-based guideline VTE prophylaxis. 39.2% of patients that met high-risk VTE criteria (Caprini > 5) received appropriate Caprini score-based prophylaxis. In multivariate regression analysis, the American Society of Anesthesiologists (ASA) score (OR 2.37, CI 1.27-4.45, p < 0.0001) and Caprini score (OR 1.13, CI 1.03-1.24, p = 0.008) predicted postoperatively VTE occurrence. Increasing Charlson comorbidity score (OR 1.39, CI 1.31-1.47, P < 0.001) ASA score (OR 1.36, CI 1.19-1.55, P < 0.001) and Caprini score (OR 1.10, CI 1.08-1.13, P < 0.001) were associated with increased odds of receiving appropriate inpatient VTE prophylaxis.

CONCLUSION

While the overall incidence of VTE was low in this cohort, enhanced adherence to risk-based practice guidelines may provide more patient benefit than harm to postoperative gynecologic patients.

The Cost Impact of Telehealth Interventions in Pediatric Surgical Specialties: A Systematic Review

BACKGROUND

Telehealth is a rapidly expanding care modality in the United States. Pediatric surgical patients often require complex care which can incur significant expenses, some of which may be alleviated by telehealth. We performed a systematic review comparing telehealth and in-person visits, and telehealth's impacts on the cost of healthcare across pediatric surgical specialties.

METHODS

A systematic review was performed using the following databases: PubMed (MEDLINE), Scopus (Elsevier), and CINAHL (EBSCOHost), searched from inception to July 10th, 2022. Studies were included per the following criteria: (1) investigated a telehealth intervention for pediatric surgical care and (2) provided some metric of telehealth cost compared to an in-person visit. Non-English or studies conducted outside of the U.S. were excluded.

RESULTS

Fourteen manuscripts met inclusion criteria and presented data on 7992 visits, including patients with a weighted average age of 7.5 ± 3.5 years. Most (11/14) studies used telehealth in a synchronous, or "real-time" context. Of the studies which calculated dollar cost savings for telehealth visits compared to in-person appointments we found a substantial range of savings per visit, from $48.50 to $344.64. Cost savings were frequently realized in terms of reduced travel expenditures, lower opportunity costs (e.g. lost wages), and decreased hospital labor requirements.

CONCLUSIONS

This review suggests that telehealth provides cost incentives to pediatric surgical care in many scenarios, including post-operative visits and some routine clinic visits. Future work should focus on standardizing the metrics by which cost impacts are analyzed and detailing which visits are most appropriately facilitated by telehealth.

Neurophenotypes of COVID-19: Risk factors and recovery outcomes

Coronavirus disease 2019 (COVID-19) infection is associated with risk of persistent neurocognitive and neuropsychiatric complications. It is unclear whether the neuropsychological manifestations of COVID-19 present as a uniform syndrome or as distinct neurophenotypes with differing risk factors and recovery outcomes. We examined post-acute neuropsychological profiles following SARS-CoV-2 infection in 205 patients recruited from inpatient and outpatient populations, using an unsupervised machine learning cluster analysis, with objective and subjective measures as input features. This resulted in three distinct post-COVID clusters. In the largest cluster (69%), cognitive functions were within normal limits, although mild subjective attention and memory complaints were reported. Vaccination was associated with membership in this "normal cognition" phenotype. Cognitive impairment was present in the remaining 31% of the sample but clustered into two differentially impaired groups. In 16% of participants, memory deficits, slowed processing speed, and fatigue were predominant. Risk factors for membership in the "memory-speed impaired" neurophenotype included anosmia and more severe COVID-19 infection. In the remaining 15% of participants, executive dysfunction was predominant. Risk factors for membership in this milder "dysexecutive" neurophenotype included disease-nonspecific factors such as neighborhood deprivation and obesity. Recovery outcomes at 6-month follow-up differed across neurophenotypes, with the normal cognition group showing improvement in verbal memory and psychomotor speed, the dysexecutive group showing improvement in cognitive flexibility, and the memory-speed impaired group showing no objective improvement and relatively worse functional outcomes compared to the other two clusters. These results indicate that there are multiple post-acute neurophenotypes of COVID-19, with different etiological pathways and recovery outcomes. This information may inform phenotype-specific approaches to treatment.

Mortality assessment for pancreas transplants in the United States over the decade 2008-2018

BACKGROUND

Pancreas transplant is the only treatment that establishes normal glucose levels for patients diagnosed with diabetes. However, since 2005, no comprehensive analysis has compared survival outcomes of: (1) Simultaneous pancreas-kidney (SPK) transplant; (2) Pancreas after kidney (PAK) transplant; and (3) Pancreas transplant alone (PTA) to waitlist survival.

AIM

To explore the outcomes of pancreas transplants in the United States during the decade 2008-2018.

METHODS

Our study utilized the United Network for Organ Sharing Standard Transplant Analysis and Research file. Pre- and post-transplant recipient and waitlist characteristics and the most recent recipient transplant and mortality status were used. We included all patients with type I diabetes listed for pancreas or kidney-pancreas transplant between May 31, 2008 and May 31, 2018. Patients were grouped into one of three transplant types: SPK, PAK, or PTA.

RESULTS

The adjusted Cox proportional hazards models comparing survival between transplanted and non-transplanted patients in each transplant type group showed that patients who underwent an SPK transplant exhibited a significantly reduced hazard of mortality [hazard ratio (HR) = 0.21, 95% confidence intervals (CI): 0.19-0.25] compared to those not transplanted. Neither PAK transplanted patients (HR = 1.68, 95%CI: 0.99-2.87) nor PTA patients (HR = 1.01, 95%CI: 0.53-1.95) experienced significantly different hazards of mortality compared to patients who did not receive a transplant.

CONCLUSION

When assessing each of the three transplant types, only SPK transplant offered a survival advantage compared to patients on the waiting list. PKA and PTA transplanted patients demonstrated no significant differences compared to patients who did not receive a transplant.

Treatment Options in Mal de Débarquement Syndrome: A Scoping Review

OBJECTIVE

The purpose of this study was to review current treatment options available for mal de debarquement syndrome (MdDS).

DATA SOURCES

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Review guidelines, we performed systematic search queries for MdDS-related texts. Documents must have been in the English language, and the time frame was all documents up until May 23, 2022.

METHODS

Studies were selected if they were published in a peer-reviewed journal and if one of the primary objectives was the assessment of treatment for MdDS. The quality and validity of all documents were assessed by two independent co-investigators. Conflicts were resolved by a third investigator.

RESULTS

One hundred ninety-four unique references were identified and underwent review. Ninety-seven were selected for full-text review, and 32 studies were ultimately included. Data were stratified by treatment methodology for MdDS. The categories used were pharmacologic, physical therapy, and neuromodulating stimulation.

CONCLUSIONS

Improvement in patient-reported outcomes is reported with several treatment modalities including specific protocols of vestibular rehabilitation, neuromodulating stimulation, and pharmacologic management with several types of neurotropic drugs.

Impact of Recipient Age at Liver Transplant on Long-term Outcomes

BACKGROUND

The age of a liver transplant (LT) candidate is one of many variables used in the transplant selection process. Most research about the age at transplant has used prespecified age ranges or categories in assessing associations with transplant outcomes. However, there is a lack of knowledge about the age at transplant and survival. This study aimed to examine associations of age at transplant as a continuous variable, in conjunction with other patient and disease-related factors, with patient and graft survival after LT.

METHODS

We used the Standard Transplant Analysis and Research data to identify LT recipients between January 2002 and June 2018. Cox regression models with a restricted cubic spline term for age examined associations with graft and patient survival after LT. We assessed the interactions of age with recipients' sex, race/ethnicity, region, indication for transplant, body mass index, model for end-stage liver disease score, diabetes, functional status at transplant, and donor risk index.

RESULTS

Age at the time of LT showed a nonlinear association with both graft and patient survival. Each demographic, clinical, transplant-related, and donor-related factor influenced these relationships differently.

CONCLUSIONS

Our results suggest that some older LT candidates may be better than some younger candidates and that clinicians should not exclusively use age to determine who receives LT.

Can counter-advertising exposing alcohol sponsorship and harms influence sport spectators' support for alcohol policies? An experimental study

BACKGROUND

Exposure to alcohol advertising and sponsorship through elite sport is associated with harmful use of alcohol. Owing to strong financial and cultural ties between alcohol and sport in Australia, policy action to restrict alcohol sport sponsorship is unlikely to occur without strong public support for change. This study tested whether exposure to counter-advertising exposing industry marketing of harmful products-a technique shown to be effective in tobacco control-promotes higher support for policy change and less favourable beliefs about the alcohol industry among sport spectators.

METHODS

A sample of 1,075 Australian adults aged 18-49 years who planned to watch an National Rugby League (NRL) State of Origin series game, featuring prominent alcohol sponsorship, was recruited through an online panel and randomly assigned to one of three conditions: control (neutral advertisement); counter-advertisement exposing alcohol harms; counter-advertisement exposing alcohol sponsorship and harms. Participants completed a pre-test questionnaire and viewed their assigned counter-advertisement multiple times in the 5-7 days before the NRL game. Within four days of watching the game, participants completed post-test measures.

RESULTS

Compared to both the control advertisement and the counter-advertisement exposing alcohol harms, participants who viewed the counter-advertisement exposing alcohol sponsorship and harms were significantly more likely to indicate support for each of four policies aimed at restricting sports-related alcohol marketing, including the complete removal of alcohol sponsorship from sport (51% vs. 32% and 37%). They were also significantly less likely to agree with statements such as "alcohol companies should be allowed to sponsor sport since their products are legal" (39% vs. 63% and 60%) and significantly less likely to report liking alcohol companies in general (38% vs. 59% and 54%). There were no significant differences in policy support or industry beliefs between participants who saw the counter-advertisement exposing alcohol harms and those who saw the control advertisement.

CONCLUSION

Counter-advertising employing messages that expose and critique the intent and impact of pervasive alcohol sponsorship in sport has potential to bolster public support for policies targeting alcohol sport sponsorship, diminish beliefs supportive of alcohol industry marketing strategies and enhance negative views of alcohol companies and their marketing practices.

Neurophenotypes of COVID-19: risk factors and recovery outcomes

Coronavirus disease 2019 (COVID-19) infection is associated with risk of persistent neurocognitive and neuropsychiatric complications, termed "long COVID". It is unclear whether the neuropsychological manifestations of COVID-19 present as a uniform syndrome or as distinct neurophenotypes with differing risk factors and recovery outcomes. We examined post-acute neuropsychological profiles following SARS-CoV-2 infection in 205 patients recruited from inpatient and outpatient populations, using an unsupervised machine learning cluster analysis, with objective and subjective measures as input features. This resulted in three distinct post-COVID clusters. In the largest cluster (69%), cognitive functions were within normal limits, although mild subjective attention and memory complaints were reported. Vaccination was associated with membership in this "normal cognition" phenotype. Cognitive impairment was present in the remaining 31% of the sample but clustered into two differentially impaired groups. In 16% of participants, memory deficits, slowed processing speed, and fatigue were predominant. Risk factors for membership in the "memory-speed impaired" neurophenotype included anosmia and more severe COVID-19 infection. In the remaining 15% of participants, executive dysfunction was predominant. Risk factors for membership in this milder "dysexecutive" neurophenotype included disease-nonspecific factors such as neighborhood deprivation and obesity. Recovery outcomes at 6-month follow-up differed across neurophenotypes, with the normal cognition group showing improvement in verbal memory and psychomotor speed, the dysexecutive group showing improvement in cognitive flexibility, and the memory-speed impaired group showing no objective improvement and relatively worse functional outcomes compared to the other two clusters. These results indicate that there are multiple post-acute neurophenotypes of long COVID, with different etiological pathways and recovery outcomes. This information may inform phenotype-specific approaches to treatment.
