Background Tubulointerstitial inflammation (TII) in lupus nephritis is associated with a worse prognosis. Vimentin, a filamental antigen, is commonly targeted by in situ activated B-cells in TII. The prognostic importance of high serum anti-vimentin antibodies (AVAs) in lupus nephritis and their relationship with common lupus autoantibody specificities is unknown. Herein we investigated associations between AVA isotypes, other autoantibodies, and response to mycophenolate mofetil (MMF) in the presence or absence of rituximab. Methods The Translational Research Initiative in the Department of Medicine (TRIDOM) cross-sectional cohort of 99 lupus patients was assayed for IgG-, IgA- and IgM- AVAs, lupus-associated and rheumatoid arthritis-associated antibodies, and hierarchically clustered. Serum from baseline, 26 and 52 weeks from 132 Lupus Nephritis Assessment with Rituximab (LUNAR) trial enrolled lupus nephritis patients was also analysed and correlated with renal function up to week 78. Results In TRIDOM, AVAs, especially IgM AVAs, clustered with IgG anti-dsDNA and away from anti-Sm and -RNP and rheumatoid arthritis-associated antibodies. In LUNAR at baseline, AVAs correlated weakly with anti-dsDNA and more strongly with anticardiolipin titers. Regardless of treatment, IgG-, but not IgM- or IgA-, AVAs were higher at week 52 than at baseline. In contrast, anti-dsDNA titers declined, regardless of therapeutic regime. High IgG AVA titers at entry predicted less response to therapy. Conclusion AVAs, especially IgG AVAs, are unique in distribution and response to therapy compared with other commonly measured autoantibody specificities. Furthermore, high-titer IgG AVAs identify lupus nephritis patients resistant to conventional therapies. These data suggest that AVAs represent an independent class of prognostic autoantibodies.
A comparison of the performance of the 2019 European League Against Rheumatism/American College of Rheumatology criteria and the 2012 Systemic Lupus International Collaborating Clinics criteria with the 1997 American College of Rheumatology classification criteria for systemic lupus erythematous in new-onset Chinese patients

Background New criteria published by the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR) use a point system that gives varying weight to each of 22 criteria. The aim of this study was to compare the performance of the 2019 EULAR/ACR criteria and the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria with the 1997 ACR criteria in a Chinese cohort. Methods A cross-sectional observation study of patients with a clinical diagnosis of SLE was performed. We collected 199 new-onset SLE patients and 175 control subjects. The data were retrospectively collected to establish the patients who fulfilled the 1997 ACR, 2012 SLICC and 2019 EULAR/ACR criteria. The sensitivity and specificity of the three classification criteria were compared using McNemar’s test. Results The sensitivity and specificity of the 2019 EULAR/ACR criteria were 96.5% and 90.3%, respectively. For the 2012 SLICC criteria, the sensitivity and specificity were 92.0% and 84.0%, respectively, while for the 1997 ACR criteria, these two values were 75.4% and 96.0%. Leucopaenia (62%), arthritis (54%) and autoimmune haemolysis (45%) were the most frequently observed clinical manifestations in the group that fulfilled the 2019 EULAR/ACR criteria. Fever was reported by 39% of participants. Conclusion Compared with the 1997 ACR and 2012 SLICC criteria, the 2019 EULAR/ACR criteria performed best in terms of sensitivity but less well in terms of specificity in Chinese new-onset lupus patients.

Published: March 2020

Background Patient-centeredness, respect for patient autonomy, and shared decision-making have now made it to center stage in discussions on quality of care. Knowing what actually counts in care and how it should be accomplished from the patients’ and nurses’ perspective seems crucial. Aim To explore how patients and their nurses perceive the importance and enactment of values in their healthcare. Research design An observational, cross-sectional study using a self-developed questionnaire, consisting of 15 items related to seven values (e.g. uniqueness, autonomy, professionalism, compassion, responsiveness, partnership, and empowerment) as described in the taxonomy of Bastemeijer et al. Participants and research context The survey was completed by 384 patients and 81 nurses. Participants were recruited on eight internal medicine wards of a 1000-bed university hospital in Belgium. Ethical considerations This study was approved by the ethical committee of the Ghent University Hospital (B670201836799). Findings (1) Patients and nurses prioritize values of care differently; (2) nurses report not being able to enact the values they prioritize in actual practice as much as one would like to; and (3) there is a gap in experienced delivery of a comprehensible explanation of all treatment options, a conversation based on equality, making shared decisions, and being non-judgmental between nurses and patients. Discussion Our findings challenge nurses’ overemphasis on professional compassion and uniqueness while arguing for increased attention on authentic shared decision-making and empowerment. The first step to a patient-centered culture truly involving patients in their healthcare is communication and information provision, rather than focusing on tangible and normative constructs. Conclusion Our findings revealed differences in prioritization and actual enactment of values in care between patients and nurses. This was especially so for values related to communication, provision of complete unbiased information, and shared decision-making. Nurses should prioritize providing comprehensible information and using conversations based on equality to make decision together with patients.

Published: March 2020

Girl Rising, a global campaign, uses the power of storytelling to build a movement for adolescent girls by inspiring people to change the way girls are valued, and sparking social action. We Dream, We Rise, is a social media campaign that was launched to call attention to age-old gender stereotypes that have gone unquestioned for generations and to inspire adults across the country to ‘dream as big for their girls as they do for their boys’. A descriptive evaluation of the campaign was conducted to measure its reach, saliency, and lessons learned. The campaign evaluation focused primarily on reach, engagement, perceptions of the campaign messaging, and intention to take social action. The campaign reached 25 million people, received more than 600,000 views, and engaged with more than 200,000 people, which yielded a more than 2% engagement rate compared to the industry average of 1%. While extracting meaningful information from social media campaigns can pose to be challenging, there is a need to move beyond just measures of reach. Measurement on quality, saliency, and outcomes are critical to ensuring that future campaigns are successful and yield the desired rigor, quality, and investments needed to facilitate change.

Objectives To report on selected findings from an evaluation of two consecutive quality improvement campaigns that adapted the Breakthrough Series Collaborative model to the broad topic of reducing demand for hospital care and reflect on lessons learned from their adaption of the model for subsequent collaborative improvement efforts. Methods We conducted a series of semi-structured interviews with Campaign sponsors and Collaborative team leaders as part of the broader realist evaluation of the two Campaigns. In addition, follow-up semi-structured interviews with Campaign sponsors and implementers were undertaken three years after the evaluation concluded (ex post evaluation interviews) to understand which adaptions to the Breakthrough Series Collaborative model had been the most influential. Results The interviews explored two features that differentiated the Campaigns from other Breakthrough Series Collaboratives. Firstly, the Campaigns enabled a diverse range of improvement solutions to be tested which had implications for the collaborative nature of the learning collaboratives. Secondly, two sequential Campaigns were implemented that incorporated common elements and provided the opportunity for the transfer of knowledge from one Campaign to the next. Conclusions Given widespread pressure to transform health care into a learning system, this paper provides a practical example of using cumulative insights to encourage the sustainability of collaborative improvement efforts. These insights centre on the gains from spreading improvement methodology throughout the organization and learning how to select and support successful collaborative teams.

Published: March 2020

Background There is increasing evidence that access to critical care services is not equitable. We aimed to investigate whether location of residence in Scotland impacts on the risk of admission to an Intensive Care Unit and on outcomes. Methods This was a population-based Bayesian spatial analysis of adult patients admitted to Intensive Care Units in Scotland between January 2011 and December 2015. We used a Besag–York–Mollié model that allows us to make direct probabilistic comparisons between areas regarding risk of admission to Intensive Care Units and on outcomes. Results A total of 17,596 patients were included. The five-year age- and sex-standardised admission rate was 352 per 100,000 residents. There was a cluster of Council Areas in the North-East of the country which had lower adjusted admission rates than the Scottish average. Midlothian, in South East Scotland had higher spatially adjusted admission rates than the Scottish average. There was no evidence of geographical variation in mortality. Conclusion Access to critical care services in Scotland varies with location of residence. Possible reasons include differential co-morbidity burden, service provision and access to critical care services. In contrast, the probability of surviving an Intensive Care Unit admission, if admitted, does not show geographical variation.

Published: March 2020

Background: Data quality is fundamental to the integrity of quantitative research. The role of external researchers in data quality assessment (DQA) remains ill-defined in the context of secondary use for research of large, centrally curated health datasets. In order to investigate equity of palliative care provided to Indigenous Australian patients, researchers accessed a now-historical version of a national palliative care dataset developed primarily for the purpose of continuous quality improvement. Objectives: (i) To apply a generic DQA framework to the dataset and (ii) to report the process and results of this assessment and examine the consequences for conducting the research. Method: The data were systematically examined for completeness, consistency and credibility. Data quality issues relevant to the Indigenous identifier and framing of research questions were of particular interest. Results: The dataset comprised 477,518 records of 144,951 patients (Indigenous N = 1515; missing Indigenous identifier N = 4998) collected from participating specialist palliative care services during a period (1 January 2010–30 June 2015) in which data-checking systems underwent substantial upgrades. Progressive improvement in completeness of data over the study period was evident. The data were error-free with respect to many credibility and consistency checks, with anomalies detected reported to data managers. As the proportion of missing values remained substantial for some clinical care variables, multiple imputation procedures were used in subsequent analyses. Conclusion and implications: In secondary use of large curated datasets, DQA by external researchers may both influence proposed analytical methods and contribute to improvement of data curation processes through feedback to data managers.
White-matter integrity and hearing acuity decline in healthy subjects: Magnetic resonance tractography
Authors: Alhazmi Fahad H 
Published: March 2020

Aim The association between hearing acuity and white-matter (WM) microstructure integrity was evaluated in a normal healthy population with a variety of hearing acuity using an automated tractography technique known as TRACULA (TRActs Constrained by UnderLying Anatomy) in order to investigate whether hearing acuity decline is correlated with brain structural connectivity. Methods Forty healthy controls were recruited to this study, which used a Siemens 3T Trio with a standard eight-channel head coil. Hearing acuity was assessed using pure-tone air conduction audiometry (Amplivox 2160, with Audiocups to eliminate noise and allow accurate pure-tone audiometry). Handedness and anxiety and depression were assessed for all participants in this study using the Edinburgh Handedness Inventory and the Hospital Anxiety and Depression Scale, respectively. Results This study showed a significant reduction in WM volume of the left cingulum angular bundle (CAB; t = 2.32, p = 0.02) in the mild to moderate hearing-loss group (238 ± 223 mm2) compared to the group with normal hearing (105  ± 121 mm2). The WM integrity of the left CAB was found to be significantly different ( t = 2.06, p = 0.04) in the mild to moderate hearing-loss group (0.18 ± 0.06 mm2/s) compared to the group with normal hearing (0.22 ± 0.05 mm2/s). The WM integrity of the left anterior thalamic radiation (ATR) was found to be significantly different ( t = 2.58, p = 0.014) in the mild to moderate hearing-loss group (0.33 ± 0.05 mm2/s) compared to the group with normal hearing (0.37 ± 0.03 mm2/s). A significant negative correlation was found between age and the WM integrity of the right ATR ( r = −0.33, p = 0.038), and between hearing acuity and the WM integrity of the right ATR ( r = −0.38, p = 0.013) and left CAB ( r = −0.36, p = 0.019). Discussion and conclusion: An important finding in this study is that brain structural connectivity changes in the left hemisphere seem to be associated with age-related hearing loss found mainly in the ATR and CAB tracts.
Predictive Factors for Failure of Meniscal Repair: A Retrospective Dual-Center Analysis of 918 Consecutive Cases
Authors: Ronnblad Erik , Barenius Bjorn , Engstrom Bjorn , Eriksson Karl 
Published: March 2020

Background: Meniscal surgery is one of the most common surgical procedures performed by orthopaedic surgeons. Over the past decade, awareness has increased regarding the importance of meniscal preservation to prevent the development of osteoarthritis in the knee joint. Removal of meniscal tissue can lead to a high risk of cartilage degeneration, and moreover, meniscus-preserving surgery rather than meniscal resection is likely to have better long-term outcomes. Success rates after meniscal repair range from 60% to 95%, but many reports are based on a small number of patients. Purpose/Hypothesis: The purpose of this study was to review all meniscal repairs and potential predictors for failure during a 12-year period. We hypothesized that meniscal anchors, lateral repairs, and repairs made in conjunction with an anterior cruciate ligament reconstruction (ACLR) would have fewer failures than meniscal arrows, medial repairs, and isolated repairs. We also hypothesized that younger patients and acute tears would be associated with fewer failures. Study Design: Case-control study; Level of evidence, 3. Methods: This study was a dual-center, retrospective analysis on consecutive meniscal repairs. The surgical protocols were reviewed, including type of tear, location, associated injury to the knee, and surgery. The study endpoint was failure of repair, defined as a need for reoperation and secondary partial or total meniscal resection, within 3 years. Kaplan-Meier analysis was performed to assess repair survival, with multivariate Cox regression to adjust for confounders. Results: A total of 954 meniscal repairs were performed on 918 patients (536 male patients [58%]; 382 female patients [42%]) with a mean age of 26 years (range, 12-60 years). The failure rate for the entire cohort was 22.5%. Bioabsorbable arrows had significantly more failures than all-inside sutures with anchors (hazard ratio [HR], 1.8; 95% CI, 1.2-2.5; P = .002). Medial meniscal repairs had a higher failure rate than lateral meniscal repairs (HR, 3.7; 95% CI, 2.3-6.0; P < .001). Simultaneous ACLR resulted in less failure than when no simultaneous ACLR was performed (HR, 0.5; 95% CI, 0.3-0.9; P = .009). Age at repair and acuity of tear did not affect the outcome ( P = .6 and .07, respectively). Conclusion: The failure rate after meniscal repair was significantly higher on the medial side, especially when using arrows. Meniscal repairs performed concomitantly with an ACLR result in fewer reoperations.

Published: March 2020

Purpose: This work investigates the visual and anatomical outcomes of full-thickness macular hole (FTMH) repair surgery using air in comparison to gas tamponade. Methods: A retrospective consecutive review of medical records was undertaken of all patients undergoing pars plana vitrectomy for idiopathic FTMH at an academic practice from January 2010 to May 2017. Each operative report was reviewed to investigate the agent used for tamponade at the end of the surgery. Preoperative hole duration and size as measured using optical coherence tomography as well as successful postoperative hole closure were recorded. Use of gas or air was not randomized and was instilled at surgeon discretion. Results: The final analysis included 211 eyes. Gas was used as the tamponade agent in 171 of the 211 eyes; most of these eyes (144 of 171) received sulfur hexafluoride (SF6) and the remainder received perfluoropropane (C3F8). Forty eyes underwent only a complete fluid-air exchange without any gas placement following vitrectomy. There was no statistically significant difference between the 2 groups in mean preoperative macular hole size ( P = .43). Nine of the 171 macular holes receiving gas tamponade failed to close (5.3%). One of the 40 macular holes receiving only air failed to close (2.5%). There was no statistically significant difference in hole closure rates between the 2 groups ( P = .45). Conclusions: Air served as an equally efficacious internal tamponade agent in comparison to nonexpansile gas following idiopathic FTMH repair surgery.

Published: March 2020

Objective: To describe patient characteristics, treatment patterns, and health care costs among patients diagnosed with major headache disorders overall and by type (tension-type headache [TTH], migraine, cluster headache [CH], or >1 primary headache type), and secondarily to evaluate drug treatment patterns among triptan initiators with a major headache diagnosis. Methods: Using US claims data from January 2012 through December 2017, we identified adults with evidence of a major headache disorder: TTH, migraine, or CH; the first diagnosis date was deemed the index date. To evaluate triptan use specifically, patients who initiated triptans were identified; the first triptan claim date was deemed the index date. Patient characteristics, treatment patterns (concomitant treatments, adherence, number of fills), and annual health care costs data were obtained. Results: Of the 418,779 patients diagnosed with major headache disorders, the following 4 cohorts were created: TTH (8%), migraine (87%), CH (1%), and >1 primary headache type (4%). The majority used analgesic (54–73%) and psychotropic (57–81%) drugs, primarily opioids (36–53%). Headache-related costs accounted for one-fifth of all-cause costs. Of the 229,946 patients who initiated triptans, the following 7 study cohorts were analyzed: sumatriptan (68%), rizatriptan (21%), eletriptan (5%), zolmitriptan (3%), naratriptan (2%), frovatriptan (1%), and almotriptan (<1%). The major concomitant analgesic medication classes were opioids (41%) and nonsteroidal anti-inflammatory drugs (34%). Conclusion: The primary headache disorder treatment paradigm is complex, with significant variability. Predominant concomitant use of opioids and switching to opioids is of concern, necessitating solutions to minimize opioid use. Switching to non-oral/fast-acting or targeted preventive therapies should be considered.

Abstract
Immunomodulatory drugs (IMiDs) are key agents for the treatment of multiple myeloma and myelodysplastic syndrome with chromosome 5q deletion. IMiDs exert their pleiotropic effects through the recruitment of neosubstrates to cereblon, a substrate receptor of the E3 ubiquitin ligase complex; therefore, identification of cell-specific neosubstrates is important to understand the effects of IMiDs. In clinical practice, IMiDs induce thrombocytopenia, which frequently results in the discontinuation of IMiD treatment. In the current study, we sought to identify the molecular mechanism underlying thrombocytopenia induced by IMiD treatment. We found that IMiDs strongly impaired proplatelet formation, a critical step in functional platelet production, through the inhibition of autocrine estradiol signaling in human megakaryocytes. Furthermore, we identified aromatase, an indispensable enzyme for estradiol biosynthesis, as a novel neosubstrate of cereblon. IMiDs promoted the recruitment of aromatase to cereblon, resulting in the degradation of aromatase in a proteasome-dependent manner. Finally, aromatase was significantly degraded in the bone marrow of patients with multiple myeloma who developed thrombocytopenia with IMiD treatment. These data suggest that aromatase is a neosubstrate of cereblon that is responsible for IMiD-induced thrombocytopenia.
