The Effect of Upper Extremity Tourniquet Time on Postoperative Pain and Opiate Consumption
Authors: Ruckle David E. , Chang Alexander C. , Wongworawat Montri Daniel 
Published: March 2022

Background: There is widespread use of pneumatic tourniquet for both upper and lower extremity orthopedic surgeries. Tourniquet use improves visualization, decreases blood loss, and as a result, decreases operative time. Exceeding a certain amount of tourniquet time can cause lasting neuromuscular damage. Orthopedic procedures cause significant pain, and the perioperative narcotic prescriptions after orthopedic surgery have been identified as one of the major contributors to the opioid epidemic. Our aim was to determine whether increasing tourniquet time had a negative impact on immediate postoperative opiate usage in the upper extremity, and to determine other factors associated with increased immediate postoperative opiate usage. Methods: A retrospective medical record review was performed on patients who underwent volar pleading for fracture fixation between January 2014 and December 2019 at a single institution. Postoperative pain, morphine equivalent dose (MED) usage, and demographic variables were collected. Multivariable analysis was performed, with P < .05 considered significant. Results: Immediate postoperative MED consumed was not correlated with operative time, tourniquet time, preoperative substance usage, or sex. However, postoperative MED consumed was correlated with preoperative narcotic use, high body mass index (BMI), and fracture surgery complexity. Conclusions: Tourniquet usage under current guidelines does not appear to have an effect on postoperative pain and narcotic usage. Preoperative narcotic usage, BMI, and surgery complexity are significant factors for postoperative opiate consumption.

Published: March 2022

Background: The thumb carpometacarpal (CMC) joint is a common source of osteoarthritis. Following trapeziectomy, ligament reconstruction with tendon interposition (LRTI) is considered a “gold standard” treatment, but suture-only suspension arthroplasty (SSA) has recently emerged as a simpler alternative. Currently, there is no objective radiographic study comparing subsidence following these 2 techniques. Methods: This study is a retrospective review of 23 patients (10 LRTI, 13 SSA) that had at least 6 months of radiographic follow-up following thumb CMC arthroplasty. Posteroanterior radiographs at a preoperative timepoint, and at the 2-week and greater than 6-month postoperative timepoints were evaluated for actual trapezial height, as well as trapezial height normalized to capitate, thumb metacarpal, and proximal phalangeal heights. Normalized trapezial heights were calculated, and preoperative values were compared with greater than 6-month postoperative values. In addition, actual and normalized trapezial heights following LRTI and SSA were compared at each timepoint. Results: Mean trapezial height decreased from approximately 12 to 5 mm (reduction of ~60%, P < .05) in both groups with no differences when comparing LRTI and SSA at each timepoint. All normalized trapezial heights revealed differences from preoperative to greater than 6-month postoperative timepoints, but no differences between LRTI and SSA. Conclusions: Ligament reconstruction with tendon interposition and SSA exhibit equivalent actual and normalized trapezial heights over a greater than 6-month postoperative time course.

Background Venous sinus stenosis (VSS) stenting has emerged as an effective treatment for patients with Idiopathic Intracranial Hypertension (IIH). However, stenting carries risk of in-stent stenosis/thrombosis and cumulative bleeding risk from long-term dual antiplatelet (DAPT) use. Thus, we investigated the potential safety and efficacy of primary balloon angioplasty as an alternative to stenting in IIH. Methods A prospectively maintained single-center registry of IIH patients undergoing endovascular procedures was queried. Inclusion criteria included patients with confirmed IIH and angiographically demonstrable VSS who underwent interventions from 2012- 2021. Patients were dichotomized into primary balloon angioplasty (Group A) and primary stenting (Group S), comparing clinical outcomes using bivariate analyses. Results 62 patients were included with median age of 33 [IQR 26-37], 74% females. Group A (9/62) and Group S (53/62) had similar baseline characteristics. Papilledema improvement was higher in Group S at 6 weeks and 6 months (44 vs. 93, p = 0.002 and 44 vs. 92%, p = 0.004), with similar improvements across all symptoms. Group S had higher mean post-procedure venous pressure gradient change (8 vs. 3 mmHg, p = 0.02) and a lower CSF opening pressure at 6 months (23 vs. 36 cmH2O, p < 0.001). VPS rescue rate was higher in Group A (44 vs. 2%, p = 0.001). There was only one procedural complications; a subdural hematoma in Group A. Conclusions Primary VSS balloon angioplasty provides a marginal and short-lived improvement of IIH symptoms compared to stenting. These findings suggest a cautious and limited role for short-term rescue angioplasty in poor shunting and stenting candidates with refractory IIH.

Introduction The COVID-19 pandemic has led to drastic measures being implemented for the management of surgical patients across all health services worldwide, including the National Health Service in the United Kingdom. It is suspected that the virus has had a detrimental effect on perioperative morbidity and mortality. Therefore, the aim of this study was to assess the impact of the COVID-19 pandemic on these outcomes in emergency general surgical patients. Methods Emergency general surgical admissions were included in this retrospective cohort study in one of the COVID-19 hotspots in the South East of England. The primary outcome was the 30-day mortality rate. Secondary outcomes included the length of stay in hospital, complication rate and severity grade and admission rates to the ITU. Results Of 123 patients, COVID-19 was detected in 12.2%. Testing was not carried out in 26%. When comparing COVID-positive to COVID-negative patients, the mean age was 71.8 + 8.8 vs. 50.7 + 5.7, respectively, and female patients accounted for 40.0 vs. 52.6%. The 30-day mortality rate was 26.7 vs. 3.9 (OR 6.49, p = 0.02), respectively. The length of stay in hospital was 20.5 + 22.2 vs. 7.7 + 9.8 ( p < 0.01), the rate of complications was 80.0 vs. 23.7 (OR 12.9, p < 0.01), and the rate of admission to the ITU was 33.3 vs. 7.9% (OR 5.83, p = 0.01). Conclusion This study demonstrates the detrimental effect of COVID-19 on emergency general surgery, with significantly worsened surgical outcomes.

Background: The impact of social determinants of health in inflammatory bowel disease (IBD) remains understudied. We evaluated the impact of social barriers on IBD outcomes within a diverse cohort of patients. Methods: We performed a cross-sectional study on adult IBD patients and assessed known social determinants of health. We calculated the total prevalence of these barriers in the sample as a whole and within each ethnic group. We summed the number of barriers present for each individual to create a cumulative social barrier score (SBS), and we evaluated the relationship of each barrier and of the cumulative SBS with IBD outcomes, including disease activity and depressive symptoms. Results: A total of 316 patients were included in the study. Disparities in the prevalence of social barriers emerged by ethnicity: non-Hispanic Blacks reported the greatest number of social barriers, followed by Hispanic patients. Prevalent social barriers included financial strains (38.4%), (such as food insecurity), medical care delays (~30%), and low educational attainment (26.8%). Social barriers associated with poor IBD outcomes included low educational attainment, poor health literacy, and financial insecurity. High SBS was associated with greater depressive symptoms [odds ratio (OR) 1.94, 95% confidence interval (CI) 1.21–2.9, p = 0.001] and lower reported use of medications. Greater ulcerative colitis (UC) disease activity was observed in patients with greater SBS. No associations were identified between SBS and IBD surgeries, hospitalizations, or disease location. Conclusion: Our study identifies social barriers that may impact IBD care and are disproportionately higher in non-Hispanic Blacks and Hispanics in the United States. Future studies should focus on implementing interventions to reduce these barriers and improve delivery of care.
Hybrid CFD/low-order modeling of thermoacoustic limit cycle oscillations in can-annular configurations
Authors: Haeringer Matthias , Polifke Wolfgang 
Published: March 2022

We propose a hybrid strategy for modeling non-linear thermoacoustic phenomena, e.g. limit-cycle (LC) oscillations, in can-annular combustion systems. The suggested model structure comprises a compressible CFD simulation limited to the burner/flame zone of one single can, coupled to a low-order model (LOM) representing the remaining combustor. In order to employ the suggested strategy for modeling non-linear phenomena like LC oscillations, the LOM must capture non-linear flame dynamics in the cans, which are not resolved by CFD. Instead of identifying such non-linear flame models in preliminary simulations, we aim at learning the non-linear dynamics “on-the-fly”, while simulating the self-excited system under consideration. Based on the observation of flame dynamics in the CFD domain, the parameters of the employed non-linear models are estimated during run time. The present study reveals that block-oriented models, which comprise a linear dynamic part followed by a static non-linear function, are well suited for this purpose. The proposed hybrid model is applied to a laminar can-annular combustor. Results agree well with the monolithic CFD simulation of the entire combustor, while the computational cost is drastically reduced. The employed flame models, whose parameters are identified during the simulation of the self-excited LC oscillation, represent well the relevant non-linear dynamics of the considered flame.

Background: It is unknown if football players with femoroacetabular impingement (FAI) syndrome report worse burden than those with other causes of hip/groin pain, and to what extent this is mediated by cartilage defects and labral tears. Hypothesis: Football players with FAI syndrome would report worse burden than other symptomatic players, with the effect partially mediated by cartilage defects and/or labral tears. Study Design: Cross-sectional study. Level of Evidence: Level 4. Methods: Football (soccer and Australian football) players (n = 165; 35 women) with hip/groin pain (≥6 months and positive flexion–adduction–internal rotation test) were recruited. Participants completed 2 patient-reported outcome measures (PROMs; the International Hip Outcome Tool–33 [iHOT-33] and Copenhagen Hip and Groin Outcome Score [HAGOS]) and underwent hip radiographs and magnetic resonance imaging (MRI). FAI syndrome was determined to be present when cam and/or pincer morphology were present. Cartilage defects and labral tears were graded as present or absent using MRI. Linear regression models investigated relationships between FAI syndrome (dichotomous independent variable) and PROM scores (dependent variables). Mediation analyses investigated the effect of cartilage defects and labral tears on these relationships. Results: FAI syndrome was not related to PROM scores (unadjusted b values ranged from −4.693 ( P = 0.23) to 0.337 ( P = 0.93)) and cartilage defects and/or labral tears did not mediate its effect ( P = 0.22-0.97). Conclusion: Football players with FAI syndrome did not report worse burden than those with other causes of hip/groin pain. Cartilage defects and/or labral tears did not explain the effect of FAI syndrome on reported burden. Clinical Relevance: FAI syndrome, cartilage defects, and labral tears were prevalent but unrelated to reported burden in symptomatic football players.

Authors: Oishi Yuta , Son Daisuke , Hotta Satoko 
Published: March 2022

Introduction: Reflecting the rapidly aging society, there has been a worldwide increase in the number of health cafés and dementia cafés which can provide a variety of support to people with illnesses and their families in the community. Nevertheless, health cafés organized by primary care physicians are rarely reported, and the social value of these activities has not yet been fully elucidated. Objectives: This study was aimed to investigate the value and impact that the health café organized by the primary care physician, brings to the visitors, the clinic, and the community. Methods: Conversations between the author (YO), who belongs to a medical clinic that has been operating for many years in Shizuoka City, and visitors of the health café were qualitatively analyzed using Steps for Coding and Theorization (SCAT), which is a sequential and thematic qualitative analysis technique consisting of 4 steps. Results: Sixteen people participated in the study. The values and impacts of holding a health café were social support, opportunities for cognitive and behavioral changes, complementary functions to outpatient care, advantages for medical care, the creation of encounters with diverse individuals, connections with local community organizations, and motivating visitors to become proactive actors. Conclusion: It was considered valuable for physicians in community-based medical clinics to have opportunities to interact with patients and local residents outside the clinical settings. Because they can potentially enhance their role as primary care physicians in the community. In addition, the impact on the community is that local residents can receive social support, increase community ties, and make people more proactive about their health.

Background: Despite an abundance of injury research focusing on European professional soccer athletes, there are limited injury data on professional soccer players in the United States. Purpose: To describe the epidemiology of injury across multiple years in Major League Soccer (MLS) players. Study Design: Descriptive epidemiology study. Methods: A web-based health management platform was used to prospectively collect injury data from all MLS teams between 2014 and 2019. An injury was defined as an incident that required medical attention and was recorded into the health management platform anytime over the course of the 2014-2019 seasons. Injuries and exposure data were recorded in training and match settings to calculate injury incidence. Results: A total of 9713 injuries were recorded between 2014 and 2019. A mean 1.1 injuries per year per player were identified, with midfielders sustaining the largest number of injuries. The most common injuries were hamstring strains (12.3%), ankle sprains (8.5%), and adductor strains (7.6%). The mean time missed per injury was 15.8 days, with 44.2% of injuries resulting in no days missed. Overall injury incidence was 8.7 per 1000 hours of exposure, declining over the course of the investigation, with a 4.1-times greater mean incidence during matches (14.0/1000 h) than training (3.4/1000 h). Conclusion: Between 2014 and 2019, the most commonly reported injuries in MLS players were hamstring strains, ankle sprains, and adductor strains. Injury incidence during matches was 4.1 times greater when compared with training, while overall injury incidence was found to decline during the course of the study period.

Published: March 2022

Background: Despite technological advances, the overall retear rate on rotator cuff repair is still high. Patches have shown significant reduction in retear rate and pain scores; however, this is not a universal finding and conflicting results have been shown among functional shoulder scales. Purpose: To analyze previous controlled trials of the literature to bring a consensus about the effectiveness of patch use on rotator cuff repair. Study Design: Systematic review; Level of evidence, 1. Methods: The search was conducted in PubMed, Web of Science, EMBASE, Scopus, and Cochrane in April 2020. The results of rotator cuff repair with patch augmentation versus without augmentation (control) were compared through odds ratio (OR), raw mean difference (RMD), and standardized mean difference (SMD) of retear rate; functional shoulder scales; strength; and range of motion (ROM). Results: Of 733 initial studies, 7 of them met the criteria to be included in the analysis. Compared with the control group, the patch augmentation group had a significantly lower retear rate (OR, 0.32 [95% CI, 0.18 to 0.55]; P < .001), lower pain (SMD, –0.42 [–0.71 to –0.12]; P < .01), a higher University of California Los Angeles Shoulder Rating Scale (RMD, 0.87 [0.15 to 1.60], P = .017), and a trend toward higher strength (SMD, 0.95 [–0.03 to 1.94], P = .05) and lower forward elevation ROM (RMD, –10.50 [–21.86 to 0.67]; P = .06), while no changes were noted for other functional scales or for internal and external rotation ROM. Conclusion: The results point to benefits of patch augmentation in rotator cuff repair, particularly a reduction in retear rate. More interventional studies with better methodological quality should be conducted to confirm the results of this initial review.

Background: Despite the increasing prevalence of tape-type sutures, whether internal knotless anchors can consistently affix tape-type sutures has not been thoroughly investigated. Purpose: To evaluate whether substituting tape-type sutures for conventional sutures influences the suture-holding strength of internal knotless anchors. Study Design: Controlled laboratory study. Level of evidence, 5. Methods: A total of 3 internal knotless anchors were tested: a spiral core clamping anchor (Footprint Ultra PK), a winged clamping anchor (PopLok), and a spooling anchor (ReelX STT). Four constructs were compared for each type of anchor, with the anchor double or quadruple loaded with tape-type sutures or conventional sutures. The testing protocol comprised preloading suture tension to 10 N; cyclic loading, in which tension increased in increments of 10 N from 10 to 90 N; and a load-to-failure stage set at a speed of 0.5 mm/s. The clinical failure load (CFL) was defined as suture slippage of ≥3 mm. Also, 1-way analysis of variance and power analysis were used to compare the CFLs of the constructs. Results: For the quadruple-loaded spiral core clamping anchors, a significant reduction in CFLs was seen with conventional sutures over tape-type sutures (138.10 ± 4.73 vs 80.00 ± 12.25 N, respectively; P < .001). This reduction was not observed under the double-loaded condition (conventional vs tape type: 76.00 ± 5.48 vs 80.00 ± 10.00 N, respectively). Substitution of the suture materials did not significantly reduce the CFLs for the winged clamping anchors (conventional vs tape type: 40.00 ± 10.00 vs 30.00 ± 7.07 N for double loaded, respectively, and 64.00 ± 13.41 vs 50.00 ± 10.00 N for quadruple loaded, respectively) or the spooling anchors (conventional vs tape type: 62.00 ± 19.23 vs 56.32 ± 20.20N for double loaded, respectively, and 72.00 ± 21.68 vs 84.00 ± 13.42 N for quadruple loaded, respectively). Conclusion: Substituting tape-type sutures for conventional sutures increased the CFLs of some internal knotless anchors. With specific suture-anchor combinations, quadruple-loaded conventional suture anchors had CFLs higher than those of double-loaded conventional suture anchors. Clinical Relevance: When multiple tape-type sutures are used in conjunction with a clamping anchor, clinicians should note a possible reduction in CFLs and resultant early suture slippage.
