Background

Rupture of abdominal aortic aneurysm (rAAA) is associated with high case fatality rates, and risk of rupture increases with the AAA diameter. Heme oxygenase‐1 (gene

mice are more susceptible to angiotensin II‐induced AAA formation, but the regulation in human nonruptured and ruptured AAA is only poorly understood. Our hypothesis proposed that HO‐1 is reduced in AAA and lowering is inversely associated with the AAA diameter.

Methods and Results

AAA walls from patients undergoing elective open repair (eAAA) or surgery because of rupture (rAAA) were analyzed for aortic

/HO‐1 expression was 1.1‐ to 7.6‐fold upregulated in eAAA and rAAA. HO‐1 expression was 3‐fold higher in eAAA specimen with a diameter >84.4 mm, whereas HO‐1 was not different in rAAA. Other variables that are known for associations with AAA and HO‐1 induction were tested. In eAAA, HO‐1 expression was negatively correlated with aortic collagen content and oxidative stress parameters H

release, oxidized proteins, and thiobarbituric acid reactive substances. Serum HO‐1 concentrations were analyzed in patients with eAAA, and maximum values were found in an aortic diameter of 55 to 70 mm with no further increase >70 mm, compared with <55 mm.

Conclusions
Aortic HO‐1 expression was increased in eAAA and rAAA. HO‐1 increased with the severity of disease but was additionally connected to less oxidative stress and vasoprotective mechanisms.

Objectives: Over the past 30 years laryngology fellowships have grown in number and diversity. This study investigated the career trajectories of recent laryngology fellowship graduates with the purpose of informing residents considering fellowship. Study design: Cross-sectional survey Setting: Academic medical center Methods: The directors of all 27 US laryngology fellowships that graduated/recruited fellows from 2010 to 2019 were contacted, and a list of former fellows was compiled. A short survey was administered in person or via email or phone. Additional data was gathered through internet searches. Results: One hundred eighty-three fellows were identified having completed American laryngology fellowships between 2010 and 2019 (100M:83F). Fifteen percent now practice internationally and 68% are in academic practice. A higher proportion of women than men enter laryngology fellowship after otolaryngology residency. One hundred twenty-nine fellows responded to our survey. Two-thirds of former fellows report current participation in laryngology research. Seventy-two percent of former fellows are still in their first job after fellowship and 53% believe they have their ideal practice. Women were more likely to enter academics than men after laryngology fellowship. Responders were overwhelmingly satisfied with their fellowship experience, with 95% saying they would choose to pursue fellowship training again. Conclusions: Most former laryngology fellows enter academia, contribute to laryngology research, practice away from their training institution, and believe they have found their ideal practice. The results of this study may be useful to residents considering fellowship training, centers considering establishing laryngology fellowships, and practices recruiting fellowship graduates.
Higher Rate of Return to Preinjury Activity Levels After Anterior Cruciate Ligament Reconstruction With a Bone–Patellar Tendon–Bone Versus Hamstring Tendon Autograft in High-Activity Patients: Results From the New Zealand ACL Registry

Published: October 2021

Background: In primary anterior cruciate ligament (ACL) reconstruction, a bone–patellar tendon–bone (BTB) autograft is associated with lower ipsilateral failure rates. BTB autografts are associated with a higher rate of contralateral ACL injuries, which some clinicians view as a marker of success of the BTB autograft. However, there is a lack of evidence on whether BTB autografts improve the rate of return to activity and sport. Purpose: To compare the rate of return to preinjury activity levels in high-activity patients after ACL reconstruction with BTB autograft or hamstring tendon autograft. Study Design: Cohort study; Level of evidence, 3. Methods: In a high-activity cohort of patients recorded between 2014 and 2018 in the New Zealand ACL Registry, prospectively collected data on preinjury and postoperative Marx activity scores were analyzed. The proportion of patients who returned to their preinjury activity levels at 1- and 2-year follow-up was compared between graft types. Results: Overall, 11.3% (208/1844) of patients returned to their preinjury activity levels at 1-year follow-up, and 15.5% (184/1190) returned at 2-year follow-up. At 1-year follow-up, 17.2% of patients with a BTB autograft returned to their preinjury activity levels compared with 9.3% of patients with a hamstring tendon autograft (adjusted odds ratio, 1.59 [95% CI, 1.16-2.17]; P = .004). At 2-year follow-up, 23.3% of patients with a BTB autograft had returned to their preinjury activity levels compared with 13.3% of patients with a hamstring tendon autograft (adjusted odds ratio, 1.63 [95% CI, 1.14-2.34]; P = .008). Male sex and younger age were associated with a higher rate of return to activity at both follow-up time points. Conclusion: The use of BTB autografts increased the odds of returning to preinjury activity levels at early follow-up. A higher rate of return to activity is a possible explanation for the higher rate of contralateral ACL injuries with the use of BTB autografts.

Published: October 2021

Objective The study objective was to examine provider acceptance and genotyping responses to a best practice advisory (BPA) concerning clopidogrel and CYP2C19 intermediate and poor metabolizers within the context of a new pharmacogenomics program at a Midwestern health system . Other secondary objectives analyzed included appropriate BPA firing, the distribution of alleles in study population, indications for clopidogrel use, and impact of indication on therapy change. Methods: In this study, the progress of this program was assessed by quantifying how providers respond to BPAs generated in the electronic medical record (EMR), in the context of a single representative gene–drug–outcome relationship. Patient data was pulled via reports yielding patients with genotyped information in the EMR and cross-referenced with a report evaluating BPA firing occurrences. Results: By capturing antiplatelet therapy changes in response to CYP2C19 genotyping results, 37 patients were found that had 73 BPAs fire. Nine of those patients had alternative antiplatelet therapy ordered. Of these, 6 alternative antiplatelet therapies were ordered from the BPA. Conclusion: Providers utilized BPAs, but responded differently based on individual knowledge of genotypes and indications. Information obtained from this study can be used for provider education and as reference for future design and wording of BPAs.

Published: October 2021

Objectives The aim of the study was to evaluate whether any admission vitals correlated with the presence of brain herniation diagnosed via MRI in cats presenting with neurologic signs. Methods Medical records at two veterinary university referral centers were reviewed to identify cats that underwent brain MRI between 2010 and 2019. A control group of cats with intracranial lesions without concurrent brain herniation was analyzed for comparison. Data relating to signalment, vitals on admission, abnormalities observed on initial neurologic examination, underlying etiology, advanced imaging findings and outcome were reviewed. A Modified Glasgow Coma Scale (MGCS) score was determined retrospectively based on initial neurologic examination. Logistic regressions were performed to investigate the relationship between each risk factor and the odds of brain herniation as diagnosed on MRI. Results Thirty-two cats with brain herniation and 44 cats with abnormal brain MRI without evidence of herniation (as a control group) based on MRI findings were included. Cats with intracranial neoplasia vs other diagnoses were found to be at increased risk of herniation (odds ratio [OR] 4.8, 95% confidence interval [CI] 1.8–13.8; P = 0.001). The odds of herniation increased with age (OR 1.1, 95% CI 1.01–1.2; P = 0.031). Cats with herniation had a significantly lower level of consciousness in their MGCS score ( P <0.0001) than cats without herniation. There was no significant difference in either motor activity or brainstem reflexes between the groups ( P >0.05). Conclusions and relevance Admission heart rate and blood pressure were not associated with brain herniation. Cats with herniation were presented with a significantly lower level of consciousness in their MGCS score; however, this clinical feature cannot be directly attributable to and predictive of herniation. Older cats with intracranial neoplasia are more likely to have brain herniation.

Purpose To report the outcomes of using synthetic amniotic membrane with platelet rich plasma for the primary management of corneal perforations. Setting Ophthalmology department. Faculty of Medicine, Minia University, Minia, Egypt Methods A case series of 10 patients diagnosed with corneal perforation underwent emergency surgical procedure for repair of the perforation through the implantation of synthetic amniotic membrane with platelet-rich plasma clot under it and the application of platelet-rich plasma eye drops, with a follow up period of up to 4 weeks. Results All cases demonstrated formation of adequate intraocular pressure digitally, within the first 7 days, and all cases showed complete sealing of the corneal perforation within the 4 weeks follow up period, mild symptoms were reported only in the 1st postoperative week like foreign body sensation and lacrimation. 3 of the treated patients underwent penetrating keratoplasty after 6 months with satisfactory visual outcomes. Conclusion The combination of amniotic membrane implant and platelet rich plasma in both the clot and eye drop forms is an effective and easy accessible method for the primary management of corneal perforations

Published: October 2021

Background: Few industry sponsored trials reported satisfactory outcomes in the use of drug-eluting stents (DES) for treatment of femoropopliteal arterial disease. This study analyzed the early/late clinical outcome from a real world single center. Patient Populations/Methods: A total of 115 limbs treated with Zilver PTX were analyzed for: major adverse limb event (MALE: above ankle limb amputation/major intervention at 1 year), major adverse events (MAEs; death, amputation, and target lesion thrombosis/reintervention), primary patency (based on duplex ultrasound ± ankle brachial indexes), limb salvage, and amputation free survival rates (AFS) at 1 and 2 years. Results: Indications included claudication in 32% and critical limb threatening ischemia (CLTI) in 68%. Lesions treated included: superficial femoral artery (SFA) 66%, both SFA and popliteal artery (PA) 19% and PA 15%. Mean lesion length was 21 cm and 68% had total occlusion. 45% were Trans-Atlantic Inter-Society Consensus (TASC) TASC II D lesions and 55% A–C lesions. Mean follow-up was 18.4 months (1–76 months). Perioperative major morbidity rate was 8.7% with 0% mortality. MALE rate at 1 year was 17% (13.5% for claudication vs 19.2% for CLTI, p=0.4499). MAE rate was 30% for claudication versus 52% for CLTI (p=0.0392). Overall primary patency rates at 1 and 2 years were 75% and 54% (86% and 71% for claudication vs 70% and 46% for CLTI, respectively, p=0.0213). Primary patency rates at 1 and 2 years were 94% and 88% for TASC A-C lesions versus 50% and 16% for TASC D lesions (p<0.0001). Overall freedom from MALE rate at 1 and 2 years were 85% and 79% (86% and 86% for claudication vs 84% and 74% for CLTI, p=0.2391). These rates were 96% and 93% for TASC A-C lesions versus 70% and 50% for D lesions, respectively (p<0.0001). Limb salvage rates at 1 and 2 years were 93% and 86% (100% and 100% for claudication vs 89% and 78% for CLTI, p=0.012). Overall AFS rates at 1 and 2 years were 79% and 71% (93% and 82% for TASC A–C vs 59% and 59% for D lesions, p=0.001). Conclusion: Clinical outcomes after DES (Zilver PTX) in femoropopliteal arterial lesions were satisfactory for TASC A–C lesions but inferior/unsatisfactory for TASC D lesions.

Published: October 2021

This study aimed to analyse the clinical and radiological outcomes after ulnar head replacement and to compare partial and total ulnar head implants. Twenty-two patients with 23 implants were available with a mean follow-up time of 7 years (range 1.3 to 17) after distal radioulnar joint arthroplasty. At the final follow-up, patients had a low level of pain at rest and during effort, a median Disabilities of the Arm, Shoulder, and Hand (DASH) score of 12 and Patient-Rated Wrist Evaluation score of 12 with partial ulnar head implants, and scores of 20 and 22 in total ulnar head implants, respectively. While the range of motion in patients with partial ulnar head implants was slightly reduced in comparison with the preoperative condition and to the patients with total ulnar head implants, there was a tendency to a higher grip strength and rotational torque. Both types of prosthesis showed sigmoid notch resorptions and resorptions around the neck. We conclude that the results after partial ulnar head replacement do not significantly differ from the total ulnar head implants in many aspects. Level of evidence: III

Published: October 2021

Background: Patients with obstructive lung diseases may be at risk of hospitalization and/or death due to COVID-19. Aim: To estimate the frequency of severe COVID-19, and COVID-19-related mortality in a well-defined large population of patients with asthma and chronic inflammatory lung disease (COPD). Further to assess the frequency of asthma and COPD as registered comorbidities at discharge from hospital, and in death certificates. Methods: At the start of the pandemic, the Swedish National Airway Register (SNAR) included 271,404 patients with a physician diagnosis of asthma and/or COPD. In September 2020, after the first COVID-19 wave in Sweden, the database was linked with the National Patient Register (NPR), the Swedish Intensive Care Register and the Swedish Cause of Death Register, which all provide data about COVID-19 based on International Classification of Diseases (ICD-10) codes. Severe COVID-19 was defined as hospitalization and/or intensive care or death due to COVID-19. Results: Among patients in SNAR, 0.5% with asthma, and 1.2% with COPD were identified with severe COVID-19. Among patients  < 18 years with asthma, only 0.02% were severely infected. Of hospitalized adults, 14% with asthma and 29% with COPD died. Further, of patients in SNAR, 56% with asthma and 81% with COPD were also registered in the NPR, while on death certificates the agreement was lower (asthma 24% and COPD 71%). Conclusion: The frequency of severe COVID-19 in asthma and COPD was relative low. Mortality for those hospitalized was double as high in COPD compared to asthma. Comorbid asthma and COPD were not always identified among patients with severe COVID-19.

Abstract
von Willebrand disease (VWD) is associated with significant morbidity as a result of excessive mucocutaneous bleeding. Early diagnosis and treatment are important to prevent and treat these symptoms. We systematically reviewed the accuracy of diagnostic tests using different cutoff values of von Willebrand factor antigen (VWF:Ag) and platelet-dependent von Willebrand factor (VWF) activity assays in the diagnosis of VWD. We searched Cochrane Central Register for Controlled Trials, MEDLINE, and Embase databases for eligible studies. We pooled estimates of sensitivity and specificity and reported patient-important outcomes when relevant. This review included 21 studies that evaluated VWD diagnosis. The results showed low certainty in the evidence for a net health benefit from reconsidering the diagnosis of VWD vs removing the disease diagnosis in patients with VWF levels that have normalized with age. For the diagnosis of type 1 VWD, VWF sequence variants were detected in 75% to 82% of patients with VWF:Ag &lt; 0.30 IU/mL and in 44% to 60% of patients with VWF:Ag between 0.30 and 0.50 IU/mL. A sensitivity of 0.90 (95% confidence interval [CI], 0.83-0.94) and a specificity of 0.91 (95% CI, 0.76-0.97) were observed for a platelet-dependent VWF activity/VWF:Ag ratio &lt; 0.7 in detecting type 2 VWD (moderate certainty in the test accuracy results). VWF:Ag and platelet-dependent activity are continuous variables that are associated with an increase in bleeding risk with decreasing levels. This systematic review shows that using a VWF activity/VWF:Ag ratio &lt; 0.7 vs lower cutoff levels in patients with an abnormal initial VWD screen is more accurate for the diagnosis of type 2 VWD.

Abstract
Cytomegalovirus (CMV) reactivation is a frequent complication after allogeneic hematopoietic cell transplantation (HCT), whose impact on clinical outcome, in particular on leukemic relapse, is controversial. We retrospectively analyzed 687 HCT recipients with acute myeloid leukemia (AML) and ciclosporin-based immunosuppression to better understand the differential impact of CMV on transplant outcomes depending on AML disease stage and in vivo T cell depletion with antithymocyte globulin (ATG). Without ATG, CMV reactivation associated with significantly reduced relapse, yet its effect was more pronounced for advanced disease AML (P = .0002) than for patients in first complete remission (CR1, P = .0169). Depending on the disease stage, ATG exposure abrogated relapse protection following CMV reactivation in advanced stages (P = .796), while it inverted its effect into increased relapse for CR1 patients (P = .0428). CMV reactivation was associated with significantly increased nonrelapse mortality in CR1 patients without ATG (P = .0187) but not in those with advanced disease and ATG. Following CMV reactivation, only patients with advanced disease had significantly higher event-free survival rates as compared with patients without CMV. Overall, our data suggest that both ATG and disease stage modulate the impact of post-HCT CMV reactivation in opposite directions, revealing a level of complexity that warrants future studies regarding the interplay between antivirus and antitumor immunity.

BackgroundPsychotic experiences are reported by 5–10% of young people, although only a minority persist and develop into psychotic disorders. It is unclear what characteristics differentiate those with transient psychotic experiences from those with persistent psychotic experiences that are more likely to be of clinical relevance.AimsTo investigate how longitudinal profiles of psychotic experiences, created from assessments at three different time points, are influenced by early life and co-occurring factors.MethodUsing data from 8045 individuals from a birth cohort study, longitudinal profiles of psychotic experiences based on semi-structured interviews conducted at 12, 18 and 24 years were defined. Environmental, cognitive, psychopathological and genetic determinants of these profiles were investigated, along with concurrent changes in psychopathology and cognition.ResultsFollowing multiple imputations, the distribution of longitudinal profiles of psychotic experiences was none (65.7%), transient (24.1%), low-frequency persistent (8.4%) and high-frequency persistent (1.7%). Individuals with high-frequency persistent psychotic experiences were more likely to report traumatic experiences, other psychopathology, a more externalised locus of control, reduced emotional stability and conscientious personality traits in childhood, compared with those with transient psychotic experiences. These characteristics also differed between those who had any psychotic experiences and those who did not.ConclusionsThese findings indicate that the same risk factors are associated with incidence as with persistence of psychotic experiences. Thus, it might be that the severity of exposure, rather than the presence of specific disease-modifying factors, is most likely to determine whether psychotic experiences are transient or persist, and potentially develop into a clinical disorder over time.
