Authors: Eason Bailey E , Vest Tyler A , Mieure Katherine D. , Neal Danielle , Tryon Jennifer 
Published: June 2021

Purpose: Controlled substances management is highly regulated, and requires institutions to have processes in place to maintain a closed-loop. This study was conducted to comprehensively evaluate the current state of controlled substances management, propose optimization opportunities, and implement steps to align the medication use process (MUP) to a defined desired state. Methods: This evaluation was conducted in 2 phases. In phase 1, the current state of controlled substances management was assessed in order to develop a gap analysis tool and failure mode and effects analysis (FMEA). In phase 2, a work group was assembled to address opportunities within the FMEA. The work group prioritized opportunities using the risk priority number (RPN), and formulated action steps to align processes with the defined desired state. Results: Through the literature evaluation, a desired state, consisting of 86 segments, was defined and compared with a gap analysis tool. Direct observation of the MUP allowed for development of 13 process maps depicting current state. Of the 86 segments, it was determined the study institution had a compliance rate of 62%. The remaining 38% correlated with 55 actionable process opportunities that were included in the FMEA. To date, 31 of the 55 (56%) opportunities have been successfully addressed by the work group. Conclusion: Use of direct observation to formulate a gap analysis tool and FMEA is an effective modality to evaluate controlled substances processes. These tools allow for pharmacy departments to identify and prioritize opportunities to optimize controlled substances management within an academic medication center

A short columella and a flattened nasal tip are the characteristic stigmata of patients with complete bilateral cleft lip and palate (BCLP). Objective: The aim of this study was to assess the nasal shape of young adults with BCLP treated with primary surgical columella lengthening and nasoalveolar molding (NAM). Setting and Patients: A group of 28 young adult patients with BCLP (mean age: 19.1±1.4 years) was compared through normalized photogrammetry to a control of 28 age- and sex-matched noncleft young adults. Results: Nasal protrusion and length of the columella were not different from noncleft young adults. On the other hand, nasolabial angle, columellar width, interalar, and nasal tip width were significantly wider than the noncleft controls. Thus, 27% of the patients have requested at this time secondary correction of the excessive nasal width. Conclusions: Both NAM and primary rhinoplasty in patients with BCLP resulted in a near normal length of the columella and nasal projection until young adulthood. Nevertheless, width of all nasal features was significantly wider than the noncleft population and required secondary nasal correction in one-third of the sample.

Published: June 2021

Objective: We aimed to assess significant ethnic variabilities in infants’ nasolabial anthropometry to motivate variations in surgical correction of a synchronous bilateral cleft lip/nasal anomaly, specifically whether a long columella is a European feature, therefore accepting a short columella and/or delayed columellar lengthening suitable for reconstruction in ethnic patients. Methods: Thirty-three infants without craniofacial pathology (10 African American [AA], 7 Hispanic [H], and 16 of European descent [C]), ages 3 to 8 months, presenting to the Johns Hopkins All Children’s general pediatric clinic were recruited. Four separate 3D photographs (2 submental and frontal views each) were taken using the Vectra H1 handheld camera (Canfield Imaging). Eighteen linear facial distances were measured using Mirror 3D analysis (Canfield Imaging Systems). Difference between ethnicities was measured using analysis of variance with the Bonferroni/Dunn post hoc comparisons. Pearson correlation was employed for interrater reliability. All statistical analyses were carried out using SPSS version 21.0 (IBM Corp), with statistical significance set at P < .05. Results: Nasal projection (sn-prn) and columella length (sn-c) did not differ significantly between groups ( P = .9). Significant differences were seen between ethnic groups in nasal width (sbal-sbal [C-AA; P = .02]; ac-ac [C-AA; P = .00; H-AA; P = .04]; al-al [C-AA; P = .00; H-AA; P = .001]) and labial length (sn-ls [C-AA; P = .041]; sn-sto [C-AA; P = .005]; Cphs-Cphi L [C-AA; P = .013]; Cphs-Cphi R [C-AA; P = .015]). Interrater reliability was good to excellent and significantly correlated for all measures. Conclusions: African American infants exhibited wider noses and longer lips. No difference was noted in nasal projection or columella length, indicating that these structures should be corrected during the primary cleft lip and nasal repair for all patients and should not be deferred to secondary correction.
Impact of Weight-Band Dosing of Tinzaparin for Venous Thromboembolism Prophylaxis on Persistent Wound Drainage in Adult Patients Undergoing Hip and Knee Arthroplasty

Published: June 2021

Background: Persistent wound drainage and venous thromboembolism (VTE) are potential complications of total joint arthroplasty, and these risks can be challenging to balance in clinical practice. Anecdotal observation has suggested that following joint arthroplasty, persistent wound drainage occurs more frequently with higher body weight and higher doses of tinzaparin when compared with lower body weight and lower doses of tinzaparin. Objective: The overall purpose of this study was to describe the impact of a tinzaparin weight-band dosing table for VTE prophylaxis on wound healing, thrombosis, and bleeding outcomes in patients undergoing total joint arthroplasty. Methods: This retrospective chart review included patients who underwent total hip or knee arthroplasty and received tinzaparin for thromboprophylaxis per their weight-banding category. The primary outcome was the incidence of persistent wound drainage. Secondary outcomes include the occurrence of VTE and clinically important bleeding during hospital admission. Results: A total of 231 patients were included in the analysis. There was no significant difference in persistent wound drainage between the 3 weight categories, and there were no differences in rates of VTE or clinically important bleeding. Concurrent use of low-dose acetylsalicylic acid was associated with a 3-fold increased risk of persistent wound drainage (risk ratio = 3.35; 95% CI = 2.14-5.24; P = 0.00003). Conclusion and Relevance: In joint arthroplasty patients, we observed no significant difference in rates of persistent wound drainage between various weight categories receiving different weight-banded doses of tinzaparin. Our results do not suggest that the current weight-band dosing table for tinzaparin needs to be adjusted to optimize patient outcomes.

Published: June 2021

Background: Severely displaced calcaneal fractures can result in considerable morphology derangement and may be accompanied by soft tissue compromise. Delayed operative restoration of the calcaneal morphology may result in acute retensioning of the damaged soft tissue with associated wound-related complications. In this study, we describe a staged treatment of displaced intra-articular calcaneal fractures that uses temporary transarticular Kirschner wire (K-wire) fixation and staged conversion to definite fixation. Methods: We identified all of the patients who were treated at our institution for calcaneal fractures between 2015 and 2019. A total of 17 patients with 20 calcaneal fractures were selectively treated with 2-stage management. Temporary transarticular K-wire fixation was performed 24 hours after the injury to restore calcaneal morphology and the surrounding soft tissue. After the soft tissue was considered safe, delayed open reduction and internal fixation was performed. The time to definite surgery, radiographic alignment, wound complications, time to radiographic union, and hindfoot American Orthopaedic Foot & Ankle Society (AOFAS) scores were recorded. Results: The average follow-up period was 17 months (range, 12-43). The average Böhler angle increased from a mean of −22 degrees (range, −109 to 25) to 25 degrees (range, 0 to 47) after temporary transarticular K-wire fixation. The mean time from temporary pinning to conversion to definite internal fixation was 20 (range, 10-32) days. There were no immediate postoperative complications. The average time to radiographic union was 13.7 (range, 10-16) weeks. The mean AOFAS score was 87 (range, 55-100). No infections or wound complications were reported during the follow-up period. Conclusion: Temporary transarticular pinning for staged calcaneal fracture treatment is safe and effective in restoring the calcaneal morphology. This novel and relatively simple method may facilitate delayed operation and decrease wound-related complications. Level of Evidence: Level IV, retrospective case series.

Background: Advanced magnetic resonance imaging (MRI) methods can provide more specific information about various microstructural tissue changes in multiple sclerosis (MS) brain. Quantitative measurement of T1 and T2 relaxation, and diffusion basis spectrum imaging (DBSI) yield metrics related to the pathology of neuroinflammation and neurodegeneration that occurs across the spectrum of MS. Objective: To use relaxation and DBSI MRI metrics to describe measures of neuroinflammation, myelin and axons in different MS subtypes. Methods: 103 participants (20 clinically isolated syndrome (CIS), 33 relapsing-remitting MS (RRMS), 30 secondary progressive MS and 20 primary progressive MS) underwent quantitative T1, T2, DBSI and conventional 3T MRI. Whole brain, normal-appearing white matter, lesion and corpus callosum MRI metrics were compared across MS subtypes. Results: A gradation of MRI metric values was seen from CIS to RRMS to progressive MS. RRMS demonstrated large oedema-related differences, while progressive MS had the most extensive abnormalities in myelin and axonal measures. Conclusion: Relaxation and DBSI-derived MRI measures show differences between MS subtypes related to the severity and composition of underlying tissue damage. RRMS showed oedema, demyelination and axonal loss compared with CIS. Progressive MS had even more evidence of increased oedema, demyelination and axonal loss compared with CIS and RRMS.

Background: The influence of pregnancy on long-term disability in multiple sclerosis (MS) is still controversial. Objective: To assess the risk of long-term disability worsening after pregnancy in MS women as compared with a propensity-score (PS) matched group of MS women without pregnancy. Methods: In the setting of the Italian Pregnancy Dataset, MS patients with (pregnancy group (PG)) and without pregnancy (control group (CG)) were recruited. Time to disability worsening on the Expanded Disability Status Scale (EDSS) was assessed through a multivariable Cox regression model. Results: The PS-matching retained 230 PG and 102 CG patients. After a follow-up of 6.5 +/- 3.1 years, disability worsening occurred in 87 (26.2%) women. In the multivariable analysis, disability worsening was associated with pregnancy in women with relapses in the year before conception (adjusted hazard ratio (aHR) = 1.74; 95% confidence interval (CI) 1.06–2.84; p = 0.027), higher EDSS (aHR = 1.39; 95% CI 1.12–1.74; p = 0.003), younger age (aHR = 0.95; 95% CI 0.91–0.99; p = 0.022) and shorter DMD exposure over the follow-up ( p < 0.008). Conclusion: Pregnancy in MS women with relapses in the year before conception increases the risk of long-term disability worsening. Our findings underscore the importance of counselling in MS women facing a pregnancy that should be planned after a period of clinical stability, favouring treatment optimization in patients with recent disease activity.

Objective The COR-KNOT® device is an automated suture fastener in which there is currently no consensus on its role in heart valve surgery. Our aim was thus to conduct a one-to-one comparison of clinical outcomes with a hand-tied control cohort. Methods We performed a single-center, cumulative propensity-matched retrospective cohort study on patients undergoing heart valve surgery from 1 January 2015 to 13 February 2020. Propensity score matching was performed on 693 patients, dividing them into matched COR-KNOT® ( n = 124) and hand-tied ( n = 124) groups. Results Data on baseline demographics, operative details, and clinical outcomes were analyzed and compared between the groups. The patients in both the COR-KNOT® and control groups were well-matched. For the median sternotomy (MS) all procedures subgroup, use of COR-KNOT® was associated with a decrease of around 49 min in CPB time (220.00 [168.00 to 256.00] vs 70.50 [134.00 to 236.75] min, P = 0.006) and around 32 min in ACC time (145.00 [109.00 to 189.00] vs 112.50 [81.00 to 161.75] min, P = 0.008). In the MS valve and CABG subgroup, use of COR-KNOT® was associated with a 70 min reduction in overall operation time (401.00 [354.25 to 468.75] vs 330.50 [288.50 to 370.50] min, P = 0.013), 63 min reduction in CPB time (216.50 [191.75 to 283.25] vs 153.00 [124.75 to 207.50] min, P = 0.004) and 45 min reduction in ACC time (146.00 [134.50 to 205.50] vs 100.50 [71.50 to 150.75] min, P = 0.003). Conclusions In heart valve surgery, use of the automated suture fastener was associated with shorter CPB and ACC times. Additionally, we determined that clinical outcomes are most likely unaffected by the use of COR-KNOT®.

Introduction The Achilles tendon is the most frequently ruptured tendon. Prompt diagnosis of this injury ensures optimal management decisions are instituted early ensuring the best outcome and patient experience, at minimal cost to the United Kingdom National Health Service. Despite this, regional and national variations to diagnosis and management exist, with anecdotal evidence of inefficiencies in the local patient pathway. To explore this further, a retrospective departmental audit of timescales from presentation to ultrasound diagnosis and definitive treatment decision was undertaken. Methods All suspected Achilles tendon ruptures in 2018 were identified through electronic and written patient records, and information on timescales involved in the diagnosis and management of each compiled. Descriptive statistics were used to map each step of the pathway and timescales involved, with performance assessed against local departmental standards and the Swansea Morriston Achilles Rupture Treatment (SMART) protocol. Results In total, 119 patients were identified, of which 113 received an ultrasound examination. Local departmental standards were met in the majority of cases, with 78% (n = 88) diagnosed by ultrasound within one week of the request and 83% (n = 91) given a treatment decision within two weeks of presentation. However, this was suboptimal when compared with timeframes utilised for developing the SMART protocol, with only 7% (n = 8) scanned within 48 hours of presentation. Conclusions Key areas of the patient pathway were identified for quality service improvement and redesign, with multidisciplinary discussion resulting in the development of a revised patient pathway which expedites diagnosis and treatment for these injuries.
Streaming’s Effects on Music Culture: Old Anxieties and New Simplifications
Authors: Hesmondhalgh David 
Published: June 2021

This article identifies five key themes, or sets of criticisms, that have emerged in online commentary on the new musical system centred on streaming platforms, and in related academic research: Streaming encourages ‘functional’ rather than meaningful, aesthetic musical experience. Streaming encourages bland, unchallenging music. Streaming makes musical experience passive and distracted, and music recedes into the background (here the article also discusses limitations of the widely used concepts of ‘ubiquitous music’ and ‘ubiquitous listening’). Streaming makes music tracks and songs shorter, and musical experience more fragmented. Streaming discourages and/or limits musical discovery and adventurousness. The article addresses each of these themes in turn, examining the degree to which criticisms of streaming’s effects on musical experience along these lines might be considered valid, and the degree to which they might genuinely enhance critical understanding of contemporary musical experience. It also considers these themes in relation to older forms of evaluation, particularly those that developed in the 20th century in response to the industrialisation of music, and argues that many recent criticisms problematically reproduce older anxieties and assumptions.
The impact of universal cardiopulmonary exercise testing on perioperative pathways and short-term patient outcomes following elective pancreatic surgery: A retrospective cohort study

Published: June 2021

Background The utility of Cardiopulmonary Exercise Testing (CPET) to identify higher risk surgical patients remains controversial. There is limited research investigating the value of preoperative CPET to plan perioperative pathways for patients undergoing major pancreatic surgery. Methods Retrospective cohort study, comprising two groups before and after a change in referral policy for High Risk preoperative anaesthetic clinic with CPET. Period 1 discretionary referral and Period 2: universal referral. The primary aim was to investigate the impact of this policy change on critical care use (planned vs unplanned) on the day of surgery and on delayed critical care admission. Secondary end points included a comparison of the total number of critical care bed days, days in hospital, complication rates and mortality data between the two cohorts. Results 177 patients were included; 114 in Period 1 and 63 in Period 2. There was a reduction in unplanned day of surgery postoperative admissions to critical care (28.1% vs. 11.1%, p = 0.008). Seven (6.1%) of patients in Period 1 and 1 (1.6%) patient in Period 2 had delayed admission, though no p value was calculated due to the small numbers involved. Complication rates were similar in each group. The median critical care bed days was 1 (range 0–21) days in Period 1 and 1 (0–13) days in Period 2. Conclusions A universal referral policy for preoperative CPET demonstrated a decrease in unplanned day of surgery critical care admissions and a trend towards reducing delayed (>24 h postop) critical care admission which could be investigated in a larger study. No measurable impact was seen on clinical outcomes.
Downregulation of Insulin-Like Growth Factor-1 Receptor Mediates Chondrocyte Death and Matrix Degradation in Kashin-Beck Disease

Published: June 2021

Purpose: To explore the relationship between insulin-like growth factor (IGF)-1R expression and the pathological progression of Kashin-Beck disease (KBD). Design: KBD cartilage samples were collected from 5 patients. Additionally, T-2 toxin was administered to rats fed a selenium (Se)-deficient diet, and their knee joints were collected. Human C28/I2 chondrocytes and mouse hypertrophic ATDC5 chondrocytes were cultured in vitro and treated with T-2 toxin and Se supplementation. Subsequently, the cultured human and mouse chondrocytes were treated with the IGF-1R inhibitor, picropodophyllin. Chondrocyte death and caspase-3 activity were analyzed using flow cytometry and a specific kit, respectively. Protein and mRNA expression levels of IGF-1R and matrix molecules were measured using immunohistochemistry, western blotting, and quantitative real-time reverse transcription-polymerase chain reaction analyses. Results: The cartilages from patients with KBD and T-2 toxin-treated rats on a Se-deficient diet showed significantly decreased expression of IGF-1R compared to cartilages from controls. T-2 toxin decreased IGF-1R mRNA and protein levels in both C28/I2 and hypertrophic ATDC5 chondrocytes in a dose-dependent manner; however, Se supplementation reduced the decrease of IGF-1R induced by T-2 toxin. Furthermore, inhibition of IGF-1R resulted in chondrocyte death of C28/I2 and hypertrophic ATDC5 chondrocytes, as well as decreased type II collagen expression and increased MMP-13 expression at the mRNA and protein levels. Conclusion: Downregulation of IGF-1R was associated with KBD cartilage destruction. Therefore, inhibition of IGF-1R may mediate chondrocyte death and extracellular matrix degeneration related to the pathological progression of KBD.
