Personalizing cardiovascular risk prediction for patients with systemic lupus erythematosus. Semin Arthritis Rheum 2024; 67:152468. [PMID: 38788567 DOI: 10.1016/j.semarthrit.2024.152468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 04/12/2024] [Accepted: 05/15/2024] [Indexed: 05/26/2024]
Abstract
OBJECTIVE Cardiovascular disease (CVD) risk is increased in SLE and underestimated by general population prediction algorithms. We aimed to develop a novel SLE-specific prediction tool, SLECRISK, to provide a more accurate estimate of CVD risk in SLE. METHODS We studied patients in the Brigham and Women's Hospital SLE cohort. We collected one-year baseline data including the presence of traditional CVD factors and SLE-related features at cohort enrollment. Ten-year follow-up for the first major adverse cardiovascular event (MACE; myocardial infarction (MI), stroke, or cardiac death) began at day +1 following the baseline period (index date). ICD-9/10 codes identified MACE were adjudicated by board-certified cardiologists. Least absolute shrinkage and selection operator regression selected SLE-related variables to add to the American College of Cardiology/American Heart Association (ACC/AHA) Pooled Cohort Risk Equations 10-year risk Cox regression model. Model fit statistics and performance (sensitivity, specificity, positive/negative predictive value, c-statistic) for predicting moderate/high 10-year risk (≥7.5 %) of MACE were assessed and compared to ACC/AHA, Framingham risk score (FRS), and modified FRS (mFRS). Optimism adjustment internal validation was performed using bootstrapping. RESULTS We included 1,243 patients with 90 MACEs (46 MIs, 36 strokes, 19 cardiac deaths) over 8946.5 person-years of follow-up. SLE variables selected for the new prediction algorithm (SLECRISK) were SLE activity (remission/mild vs. moderate/severe), disease duration (years), creatinine (mg/dL), anti-dsDNA, anti-RNP, lupus anticoagulant, anti-Ro positivity, and low C4. The sensitivity for detecting moderate/high-risk (≥7.5 %) of MACE using SLECRISK was 0.74 (95 %CI: 0.65, 0.83), which was better than the sensitivity of the ACC/AHA model (0.38 (95 %CI: 0.28, 0.48)). It also identified 3.4-fold more moderate/high-risk patients than the ACC/AHA. Patients who were moderate/high-risk according to SLECRISK but not ACC/AHA, were more likely to be young women with severe SLE and few other traditional CVD risk factors. Model performance between SLECRISK, FRS, and mFRS were similar. CONCLUSION The novel SLECRISK tool is more sensitive than the ACC/AHA for predicting moderate/high 10-year risk for MACE and may be particularly useful in predicting risk for young females with severe SLE. Future external validation studies utilizing cohorts with more severe SLE are needed.

Over-the-counter fish oil supplementation and pro-resolving and pro-inflammatory lipid mediators in rheumatoid arthritis. Prostaglandins Leukot Essent Fatty Acids 2023; 190:102542. [PMID: 36773395 PMCID: PMC10027850 DOI: 10.1016/j.plefa.2023.102542] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Revised: 01/17/2023] [Accepted: 01/22/2023] [Indexed: 01/28/2023]
Abstract
OBJECTIVE Little is known about the effects of over-the-counter fish oil (FO) supplements on circulating omega-3 polyunsaturated fatty acid (n-3 PUFA)-derived specialized pro-resolving mediators (SPMs), nor about whether having a chronic inflammatory disease such as rheumatoid arthritis (RA) influences SPM levels. We investigated associations between over-the-counter n-3 PUFA FO supplementation and circulating SPMs among patients with vs. without RA. METHODS We studied 104 participants: 26 with RA taking FO matched by age and sex to 26 with RA not taking FO, 26 without RA taking FO, and 26 without RA not taking FO. Targeted-liquid chromatography-tandem mass spectroscopy was performed on patient plasma to identify and quantify 27 lipid mediators (including eicosanoids and SPMs). We performed t-tests and then multivariable linear regression analyses to assess whether having RA or taking FO supplements was associated with circulating lipid mediator concentrations, adjusting for age, race, sex, smoking, body mass index, and current medication use (statins, prednisone and immunomodulators among RA cases only). We tested for interactions between FO supplementation and RA status. We also conducted Spearman's correlations between EPA, DHA, and ARA and their downstream metabolites. RESULTS Among patients who were taking FO compared to those who were not, in multivariable- adjusted analyses, SPM substrates EPA and DHA were both elevated as were several of their pro-resolving bioactive products, including 15- and 18-HEPE from EPA, and 14- and 17-HDHA from DHA, which are substrates for specific SPMs. While E-series and D-series resolvins were present and identified, we did not find statistical elevations of other SPMs. Results were similar among patients with RA and patients without RA, taking vs. not taking FO supplementation (no formal statistical interaction observed). There was a strong positive correlation between EPA and DHA and their immediate downstream SPM precursors (18-HEPE and15-HEPE from EPA; 17-HDHA and 14-HDHA from DHA) among all patients. CONCLUSION Patients taking FO supplements, regardless of RA status, not only had higher blood levels of EPA and DHA, but also of their enzymatic products 18-HEPE (E-series resolvin precursors), 15-HEPE and 17-HDHA (D-series resolvin and protectin precursors). Patients with RA, an inflammatory autoimmune disease, may be able to augment some SPM precursor reserves, similarly to matched controls without RA, by taking oral FO supplements.

Association of Healthy Lifestyle Behaviors and the Risk of Developing Rheumatoid Arthritis Among Women. Arthritis Care Res (Hoboken) 2023; 75:272-276. [PMID: 35040282 PMCID: PMC9289074 DOI: 10.1002/acr.24862] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 12/23/2021] [Accepted: 01/11/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVE To investigate whether a healthy lifestyle, defined by a healthy lifestyle index score (HLIS), was associated with rheumatoid arthritis (RA) risk, overall and with seropositive/seronegative subtypes. METHODS We analyzed female nurses in the Nurses' Health Study (NHS, 1986-2016) and NHSII (1991-2017). Lifestyle and medical information were collected on biennial questionnaires. Medical records confirmed incident RA and serostatus. The HLIS index includes 5 modifiable components: smoking, alcohol consumption, body mass index, physical activity, and diet. Cox regression, adjusted for confounders, modeled associations between HLIS and incident RA. The population attributable risk estimated the proportion of incident RA preventable if participants adopted ≥4 healthy lifestyle factors. RESULTS A total of 1,219 incident RA cases (776 seropositive, 443 seronegative) developed in 4,467,751 person-years. Higher (healthier) HLIS was associated with lower overall RA risk (hazard ratio [HR] 0.86 [95% confidence interval (95% CI) 0.82-0.90]), seropositive RA risk (HR 0.85 [95% CI 0.80-0.91]), and seronegative RA risk (HR 0.87 [95% 0.80-0.94]). Women with 5 healthy lifestyle factors had the lowest risk (HR 0.42 [95% CI 0.22-0.80]). The population attributable risk for adhering to ≥4 lifestyle factors was 34% for RA. CONCLUSION In this prospective cohort, healthier lifestyle was associated with a lower RA risk. A substantial proportion of RA may be preventable by a healthy lifestyle.

Abstract
OBJECTIVE We studied posttraumatic stress disorder (PTSD), a severe trauma-related mental disorder, and systemic lupus erythematosus (SLE) risk in a large, diverse population enrolled in Medicaid, a US government-sponsored health insurance program for low-income individuals. METHODS We identified SLE cases and controls among patients ages 18-65 years enrolled in Medicaid for ≥12 months in the 29 most populated US states from 2007 to 2010. SLE and PTSD case statuses were defined based on validated patterns of International Classification of Diseases, Ninth Revision codes. Index date was the date of the first SLE code. Controls had no SLE codes but had another inpatient or outpatient code on the index date and were matched 1:10 to cases by age, sex, and race. Conditional logistic regressions calculated odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association of PTSD with incident SLE, adjusting for smoking, obesity, oral contraceptive use, and other covariates. RESULTS A total of 10,942 incident SLE cases were matched to 109,420 controls. The prevalence of PTSD was higher in SLE cases, at 10.74 cases of PTSD per 1,000 person-years (95% CI 9.37-12.31) versus 7.83 cases (95% CI 7.42-8.27) in controls. The multivariable-adjusted OR for SLE among those with PTSD was 2.00 (95% CI 1.64-2.46). CONCLUSION In this large, racially and sociodemographically diverse US population, we found patients with a prior PTSD diagnosis had twice the odds of a subsequent diagnosis of SLE. Studies are necessary to clarify the mechanisms driving the observed association and to inform possible interventions.

Abstract
OBJECTIVES To investigate the immune cell profiles of patients with systemic lupus erythematosus (SLE), and to identify longitudinal changes in those profiles over time. METHODS We employed mass cytometry with 3 different panels of 38-39 markers (an immunophenotyping panel, a T cell/monocyte panel, and a B cell panel) in cryopreserved peripheral blood mononuclear cells (PBMCs) from 9 patients with early SLE, 15 patients with established SLE, and 14 controls without autoimmune disease. We used machine learning-driven clustering, flow self-organizing maps, and dimensional reduction with t-distributed stochastic neighbor embedding to identify unique cell populations in early SLE and established SLE. We used mass cytometry data of PBMCs from 19 patients with early rheumatoid arthritis (RA) and 23 controls to compare levels of specific cell populations in early RA and SLE. For the 9 patients with early SLE, longitudinal mass cytometry analysis was applied to PBMCs at enrollment, 6 months after enrollment, and 1 year after enrollment. Serum samples were also assayed for 65 cytokines using Luminex multiplex assay, and associations between cell types and cytokines/chemokines were assessed. RESULTS Levels of peripheral helper T cells, follicular helper T (Tfh) cells, and several Ki-67+ proliferating subsets (ICOS+Ki-67+ CD8 T cells, Ki-67+ regulatory T cells, CD19intermediate Ki-67high plasmablasts, and PU.1high Ki-67high monocytes) were increased in patients with early SLE, with more prominent alterations than were seen in patients with early RA. Longitudinal mass cytometry and multiplex serum cytokine assays of samples from patients with early SLE revealed that levels of Tfh cells and CXCL10 had decreased 1 year after enrollment. Levels of CXCL13 were positively correlated with levels of several of the expanded cell populations in early SLE. CONCLUSION Two major helper T cell subsets and unique Ki-67+ proliferating immune cell subsets were expanded in patients in the early phase of SLE, and the immunologic features characteristic of early SLE evolved over time.

Abstract
COVID-19 raised concern regarding cardiotoxicity and QTc prolongation of hydroxychloroquine (HCQ) and chloroquine (CQ). We examined the frequency and patient factors associated with ECG testing and the detection of prolonged QTc among new HCQ/CQ users in a large academic medical system. 10,248 subjects with a first HCQ/CQ prescription (1/2015–3/2020) were included. We assessed baseline (1 year prior to and including day of initiation of HCQ/CQ through 2 months after initial HCQ/CQ prescription) and follow-up (10 months after the baseline period) patient characteristics and ECGs obtained from electronic health records. Among 8384 female HCQ/CQ new users, ECGs were obtained for 22.3%, 14.3%, and 7.6%, at baseline, follow, and both periods, respectively. Among 1864 male HCQ/CQ new users, ECGs were obtained more frequently at baseline (29.7%), follow-up (18.0%), and both periods (11.3%). Female HCQ/CQ users with a normal QTc at baseline but prolonged QTc (> 470 ms) at follow-up (13.1%) were older at HCQ/CQ initiation [mean 64.7 (SD 16.5) vs. 58.7 (SD 16.9) years, p = 0.004] and more likely to have history of myocardial infarction (41.0% vs. 21.6%, p = 0.0003) compared to those who had normal baseline and follow-up QTc. The frequency of prolonged QTc development was similar (12.4%) among male HCQ/CQ new users (> 450 ms). Prior to COVID-19, ECG testing before and after HCQ/CQ prescription was infrequent, particularly for females who are disproportionately affected by rheumatic diseases and were just as likely to develop prolonged QTc (> 1/10 new users). Prospective studies are needed to guide future management of HCQ/CQ therapy in rheumatic populations.

Abstract
Although dignity has been widely explored in the context of healthcare, it has rarely been the subject of empirical exploration when care is delivered by community district nursing teams. This paper demonstrates how a commonplace community nursing task (changing dressings) can constitute a clinical lens through which to explore the ways in which community nurses can influence patients' dignity. This ethnographic study involved two research methods: interviews with patients and nurses (n=22) and observations of clinical interactions (n=62). Dignity can manifest during routine interactions between community nurses and patients. Patient-participants identified malodour from their ill-bodies as a particular threat to dignity. Nurses can reinforce the dignity of their patients through relational aspects of care and the successful concealment of 'leaky' bodies.

Abstract
OBJECTIVES The purpose of this study was to evaluate the prognostic value of quantitative myocardial blood flow (MBF) and myocardial flow reserve (MFR), reflecting the integrated effects of diffuse atherosclerosis and microvascular dysfunction in patients with systemic inflammatory disorders. BACKGROUND Rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and psoriasis (PsO) are common inflammatory conditions with excess cardiovascular (CV) risk compared to the general population. Systemic inflammation perturbs endothelial function and has been linked to coronary vasomotor dysfunction. However, the prognostic significance of this vascular dysfunction is not known. METHODS This was a retrospective study of patients with RA, SLE, and PsO undergoing clinically indicated rest and stress myocardial perfusion positron emission tomography (PET). Patients with an abnormal myocardial perfusion study or left ventricular dysfunction were excluded. MFR was calculated as the ratio of myocardial blood flow (MBF, ml/min/g) at peak stress compared to that at rest. RESULTS Among the 198 patients (median age: 65 years; 80% female), 20.7% had SLE, 31.8% had PsO, and 47.5% had RA. There were no differences in mean MFR between these conditions. Over a median follow-up of 7.8 years, there were 51 deaths and 63 major adverse cardiovascular events (MACE). Patients in the lowest tertile (MFR <1.65) had higher all-cause mortality than the highest tertile, which remained significant after adjusting for age, sex, and the pre-test clinical risk score (hazard ratio [HR]: 2.4; 95% confidence interval [CI]: 1.05 to 5.4; p = 0.038). Similarly, compared to the highest MFR tertile, those in the lowest tertile had a lower MACE-free survival after adjusting for age, sex, and the pre-test clinical risk score (HR: 3.6; 95% CI: 1.7 to 7.6; p = 0.001). CONCLUSIONS In patients with systemic inflammatory disorders, impaired coronary vasodilator reserve was associated with worse cardiovascular outcomes and all-cause mortality.

Abstract
Abstract
Background
It is estimated that at least 12-15% of abdominal operations lead to incisional hernias, and Worldwide, evidence shows high rates of recurrence after surgical repair ranging from 12.7% in the Danish hernia registry to 23% in the Swedish registry.
Method
This is a retrospective analysis of the practice of a single surgeon at a tertiary centre. An electronic database provided all hernia surgeries done by the surgeon. A total of 185 patients with complete data were included who had open hernia repair. Electronic patient records were analysed to collect the data.
Results
185 patients, with a median age of 57 years (IQR 68 – 49), and BMI of 31.14 (IQR 36.02 – 27.52), had a hernia recurrence rate of 15.6% (29/185). More than 80% of the cases were complex hernias with a European Hernia classification of M3 and/ or W3, with dense intestinal adhesions and multiple previous repairs. Variability in techniques and mesh evolved over this period, from anterior component separation to transversus abdominis release to achieve closure of the abdomen. Polypropylene meshes were used for non-contaminated or less complex cases. The use of biologics in the early years has been superseded by biosynthetic.
Conclusions
The creation of the abdominal wall unit and subsequent MDT at this centre resulted in a rise of total procedures, complexity of cases and patients with significant co-morbidities. Specialised abdominal wall surgeons are associated with better results when performing complex abdominal wall reconstructions.

Abstract
Background Systemic lupus erythematosus (SLE) is a systemic autoimmune inflammatory disorder associated with premature atherosclerosis and increased cardiovascular risk. Systemic inflammation is an emerging risk factor for coronary microvascular dysfunction (CMD). We aimed to test whether CMD, defined as abnormal myocardial flow reserve (MFR) by positron emission tomography‐computed tomography, would be independently associated with SLE after adjusting for nonobstructive atherosclerotic burden and common cardiovascular risk factors. Methods and Results Consecutive patients with SLE who underwent symptom‐prompted stress cardiac positron emission tomography‐computed tomography were included (n=42). Obstructive coronary artery disease and systolic dysfunction were excluded. MFR was quantified by positron emission tomography‐computed tomography, and CMD was defined as MFR <2. We frequency matched patients who did not have SLE and had symptom‐prompted positron emission tomography studies on age, sex, and key cardiovascular risk factors (n=69). The attenuation correction computed tomography scans were reviewed for qualitative assessment of coronary artery calcium. Patients with SLE had a more severe reduction in global MFR compared with controls and a higher prevalence of CMD, despite a similar degree of nonobstructive atherosclerotic burden (1.91±0.5 versus 2.4±0.7, respectively, P<0.0001; CMD, 57.1% versus 33.3%, respectively, P=0.017). Conclusions We demonstrated that patients with SLE with cardiac symptoms without obstructive coronary artery disease have a high prevalence of coronary vasomotor abnormalities. In comparison with symptomatic matched controls, patients with SLE have a more severe reduction in MFR that is not accounted for by common cardiovascular factors or atherosclerotic burden.

Abstract
Abstract
Background
Rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and psoriasis (PsO) are common inflammatory conditions with excess cardiovascular (CV) risk compared to the general population. This excess CV risk is associated with traditional risk factors, glucocorticoid treatment, and systemic inflammation. Systemic inflammation perturbs endothelial function and has been linked to coronary vasomotor dysfunction. It is not clear if coronary vasomotor dysfunction would be associated with worse clinical outcomes in systemic autoimmune inflammatory conditions.
Purpose
We tested the hypothesis that impaired coronary flow reserve (CFR), which in the absence of flow-limiting obstructive coronary artery disease (CAD) reflects vasomotor dysfunction, among patients with SLE, RA, and PsO is associated with worse clinical outcomes.
Methods
We included patients with RA, SLE, and PsO who underwent clinically indicated rest/stress myocardial perfusion positron emission tomography (PET) at a large academic medical center from 2006 to 2019. Patients with an abnormal myocardial perfusion study (summed stress score >3) or left ventricular ejection fraction <40% were excluded. CFR was calculated as the ratio of myocardial blood flow (MBF, ml/min/g) at peak stress compared to the MBF at rest and adjusted for baseline heart rate and blood pressure.
Results
Among the 175 patients (median age 65.1 years, 80% female) in the cohort, 24% had SLE, 35% PsO, and 41% RA. There was no difference in mean CFR between patients with RA, SLE, or PsO. Over a median follow-up of 8.5 years after PET, there were 47 deaths. Patients in the lowest and middle tertile (CFR <2.18) had a higher all-cause mortality when compared with the highest (Figure 1), and this association remained significant after adjusting for age and a composite clinical score incorporating sex, symptoms, and CV risk factors (lowest vs. highest tertile: HR 2.8; 95% confidence interval 1.2–6.5; p=0.01). CV risk factors such as diabetes, hypertension, obesity, tobacco use, and a family history of CAD were not significantly different across CFR tertiles, suggesting that inflammatory-disease specific risk factors may contribute to coronary vasomotor dysfunction.
Conclusions
In patients with systemic inflammatory disease, coronary vasomotor dysfunction was associated with worse outcomes independent of traditional CV risk factors and may have utility as a marker of CV risk among patients with inflammatory disease.

Interactions Between Genome-Wide Genetic Factors and Smoking Influencing Risk of Systemic Lupus Erythematosus. Arthritis Rheumatol 2020; 72:1863-1871.

Abstract
OBJECTIVE To identify interactions between genetic factors and current or recent smoking in relation to risk of developing systemic lupus erythematosus (SLE). METHODS For the study, 673 patients with SLE (diagnosed according to the American College of Rheumatology 1997 updated classification criteria) were matched by age, sex, and race (first 3 genetic principal components) to 3,272 control subjects without a history of connective tissue disease. Smoking status was classified as current smoking/having recently quit smoking within 4 years before diagnosis (or matched index date for controls) versus distant past/never smoking. In total, 86 single-nucleotide polymorphisms and 10 classic HLA alleles previously associated with SLE were included in a weighted genetic risk score (wGRS), with scores dichotomized as either low or high based on the median value in control subjects (low wGRS being defined as less than or equal to the control median; high wGRS being defined as greater than the control median). Conditional logistic regression models were used to estimate both the risk of SLE and risk of anti-double-stranded DNA autoantibody-positive (dsDNA+) SLE. Additive interactions were assessed using the attributable proportion (AP) due to interaction, and multiplicative interactions were assessed using a chi-square test (with 1 degree of freedom) for the wGRS and for individual risk alleles. Separate repeated analyses were carried out among subjects of European ancestry only. RESULTS The mean ± SD age of the SLE patients at the time of diagnosis was 36.4 ± 15.3 years. Among the 673 SLE patients included, 92.3% were female and 59.3% were dsDNA+. Ethnic distributions were as follows: 75.6% of European ancestry, 4.5% of Asian ancestry, 11.7% of African ancestry, and 8.2% classified as other ancestry. A high wGRS (odds ratio [OR] 2.0, P = 1.0 × 10-51 versus low wGRS) and a status of current/recent smoking (OR 1.5, P = 0.0003 versus distant past/never smoking) were strongly associated with SLE risk, with significant additive interaction (AP 0.33, P = 0.0012), and associations with the risk of anti-dsDNA+ SLE were even stronger. No significant multiplicative interactions with the total wGRS (P = 0.58) or with the HLA-only wGRS (P = 0.06) were found. Findings were similar in analyses restricted to only subjects of European ancestry. CONCLUSION The strong additive interaction between an updated SLE genetic risk score and current/recent smoking suggests that smoking may influence specific genes in the pathogenesis of SLE.

Safety of the Zoster Vaccine Recombinant Adjuvanted in Rheumatoid Arthritis and Other Systemic Rheumatic Disease Patients: A Single Center's Experience With 400 Patients. ACR Open Rheumatol 2020; 2:357-361. [PMID: 32412669 PMCID: PMC7301873 DOI: 10.1002/acr2.11150] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Accepted: 04/14/2020] [Indexed: 01/22/2023] Open
Abstract
OBJECTIVE Patients with rheumatoid arthritis (RA) and other systemic rheumatic diseases (SRDs) are at increased risk of developing herpes zoster (HZ). Zoster recombinant adjuvanted (ZRA) is a recombinant vaccine approved by the Food and Drug Administration in 2018. Concern has been raised that the ZRA may trigger disease flares in rheumatology patients who are immunocompromised. We investigated the impact of the ZRA vaccine in patients with RA and SRD and measured the incidence of flares and side effects. METHODS A flare was defined as occurring within 12 weeks of vaccine administration by either 1) documentation of RA flare in office notes, telephone encounter, or patient portal communication or 2) new or increased dose of corticosteroids. RESULTS We identified 403 patients (239 patients with RA and 164 patients with SRD) who received the ZRA vaccine from February 1, 2018, to February 1, 2019. We measured a 6.7% (n = 27) incidence of flare. Side effects occurred in 12.7% (n = 51) of patients. All flares and side effects were regarded as mild. Three cases of HZ were reported as occurring 2, 10, and 11 months after the vaccination. CONCLUSION In 403 patients who received the ZRA vaccine, the incidence of disease flares was 7% or less and that of side effects was 13% or less, both of which are less than the incidence rates observed in the pivotal trials.

Improving Quality of Care in Rheumatoid Arthritis Through Mobile Patient-Reported Outcome Measurement: Focus Group Study. JMIR Form Res 2020; 4:e15158. [PMID: 32459179 PMCID: PMC7316226 DOI: 10.2196/15158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 11/12/2019] [Accepted: 12/20/2019] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Patient-reported outcomes (PROs) for chronic disease management can be integrated into the routine workflow by leveraging mobile technology. OBJECTIVE The objective of our study was to describe the process of our quality improvement (QI) efforts using tablets for PRO collection in a busy, academic rheumatology practice to support a treat-to-target (TTT) approach for rheumatoid arthritis (RA) management. METHODS Our QI team designed a process for routine collection of PROs for RA patients at the Arthritis Center, employing information technology and an electronic medical record (EMR) system. Patients received a tablet at the clinic check-in desk to complete the Routine Assessment of Patient Index Data 3 (RAPID3) survey, a validated RA PRO. RAPID3 scores were uploaded to the EMR in real time and available for use in shared decision making during routine office visits. Weekly data were collected on RAPID3 completion rates and shared with front desk staff and medical assistants to drive improvement. Patients in our patient family advisory council and focus groups provided informal feedback on the process. RESULTS From May 1, 2017, to January 31, 2019, a total of 4233 RAPID3 surveys were completed by 1691 patients. The mean age of patients was 63 (SD 14) years; 84.00% (1420/1691) of the patients were female, and 83.00% (1403/1691) of the patients were white. The rates of RAPID3 completion increased from 14.3% (58/405) in May 2017 to 68.00% (254/376) in September 2017 and were sustained over time through January 2019. Informal feedback from patients was positive and negative, relating to the usability of the tablet and the way rheumatologists used and explained the RAPID3 data in shared decision making during the office visit. CONCLUSIONS We designed a sustainable and reliable process for collecting PROs from patients with RA in the waiting room and integrated these data through the EMR during office visits.

Abstract
Neutron beta decay is one of the most fundamental processes in nuclear physics and provides sensitive means to uncover the details of the weak interaction. Neutron beta decay can evaluate the ratio of axial-vector to vector coupling constants in the standard model, λ = gA/gV, through multiple decay correlations. The Nab experiment will carry out measurements of the electron-neutrino correlation parameter a with a precision of δa/a = 10−3 and the Fierz interference term b to δb = 3 × 10−3 in unpolarized free neutron beta decay. These results, along with a more precise measurement of the neutron lifetime, aim to deliver an independent determination of the ratio λ with a precision of δλ/λ = 0.03% that will allow an evaluation of Vud and sensitively test CKM unitarity, independent of nuclear models. Nab utilizes a novel, long asymmetric spectrometer that guides the decay electron and proton to two large area silicon detectors in order to precisely determine the electron energy and an estimation of the proton momentum from the proton time of flight. The Nab spectrometer is being commissioned at the Fundamental Neutron Physics Beamline at the Spallation Neutron Source at Oak Ridge National Lab. We present an overview of the Nab experiment and recent updates on the spectrometer, analysis, and systematic effects.

Abstract
OBJECTIVE Using a quality improvement approach, our objective was to integrate a treat-to-target approach for rheumatoid arthritis (RA) through routine electronic collection of patient-reported disease activity scores and a multidisciplinary learning collaborative for rheumatologists. METHODS RA patients completed a patient-reported outcome measure, the Routine Assessment of Patient Index Data 3 (RAPID3), at check-in. Nine rheumatologists and their patients were allocated to a learning collaborative intervention group focused on a treat-to-target approach and 13 were allocated to a control group. The primary outcome was documentation of a treat-to-target implementation score: disease activity score, disease activity score used in the medication change decision, the presence of a treatment target, and an indication of shared decision-making. A primary analysis of patient visits with medication changes was conducted using an interrupted time-series analysis. RESULTS We studied 554 individual rheumatology patients with 709 patient visits. Treat-to-target implementation scores among intervention rheumatologists (mean ± SD 44.6% ± 1.63%) were 12.4% higher than in the control group (mean ± SD 32.2% ± 1.50%; P < 0.0001). We observed differences in treat-to-target implementation score components, comparing intervention group to control group rheumatologists: disease activity score present, 77.2% versus 68.0% (P = 0.02); disease activity score used in the medication change decision, 45.2% versus 30.0% (P < 0.01); treatment target, 9.0% versus 0.4% (P < 0.01); and shared decision-making, 46.9% versus 30.0% (P < 0.01). Secondary analysis of patient visits with high RAPID3 scores found that medication changes were 54% less likely in the intervention versus control group (odds ratio 0.46 [95% confidence interval 0.27-0.79], P = 0.005). CONCLUSION This nonrandomized, interrupted time-series trial demonstrated a modest but significant impact of a learning collaborative intervention on rheumatologist documentation of a treat-to-target approach in RA.

Abstract
This report presents an obstetric patient with no significant past medical history who underwent spinal anaesthesia for a category-three caesarean section. On examination, she had asymmetrical scapular alignment and a mild scoliosis of the lumbar spine with no functional limitation. Postoperatively the patient developed neuropathic pain symptoms in the right leg which failed to resolve with conventional analgesia. Cervical and lumbar spine magnetic resonance imaging was performed resulting in a diagnosis of a low-lying tethered spinal cord terminating at the level of L5 and congenital fusion of the C7/T1 vertebrae. A tethered spinal cord is a rare condition, which in this case had been completely asymptomatic. However, we suggest that the patient displayed musculoskeletal signs not previously widely reported, which could have indicated the presence of a potential underlying neural tube defect. Based on the imaging findings and the presence of Sprengel's deformity, the patient was diagnosed with Klippel-Feil syndrome.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
SummaryWe studied immune function in Belgian haemophiliacs treated with Factor VIII from volunteer donors. No patient had clinical evidence of immune deficiency. We found a decrease in T-helper cells (p <0.0005), in the ratio of T-helper over T-cytotoxic/ suppressor cells (1.72 ± 0.47 versus 2.24 ± 0.82 in controls, p <0.005) and in lymphocyte responsiveness to mitogens (p <0.05).These findings could not be linked to the amount of F VIII received over the last year, the time since last F VIII administration, circulating immune complexes (54% positive patients, 7% positive controls, p <0.005), increased ALT levels, antibodies to cytomegalo-virus (85% of the patients, 45% of the controls, p <0.005), antibodies to Epstein-Barr virus, nor to the presence of HLA-DR 5 which was found in 56% of the haemophiliacs (20% of the overall Belgian population, p <0.005).Either F VIII induces long lasting immunological alterations unrelated to AIDS, or haemophilia is itself associated with such changes.

Abstract
Abstract
While a variety of technologies exist to measure proteins, such as ELISA’s, Mass Spec, and 2D Gel’s, the most promising for screening multiple proteins are biochip or microarray based technologies. However, even with biochip devices, measuring specific interactions between multiple protein combinations remains problematic. Proteins are complex and fragile bio-molecules and often interact in complex and unpredictable ways with other proteins and/or protein analysis equipment, causing non-specific (false) signals. Furthermore, many proteins of interest to the life science industry are present in samples at very different concentrations, limiting which proteins can be screened in a single multiplex test and sample dilution.
To address these problems, Inanovate has developed a new multiplexed protein quantification technology called Longitudinal Assay Screening (LAS), combining high sensitivity confocal imaging and microfluidics alongside protein based microarrays. Inanovate has completed testing and benchmarking of the first platform integrating LAS technology across a range of demonstration assays. Instead of depending on a 96-well micro-titer plate, the new LAS platform utilizes a glass slide based protein microarray and microfluidics for dispensing and binding samples and detection antibodies. In its most basic form, the protein microarray is composed of capture antibodies for the proteins being measured, as well as positive and negative quality control features for ensuring sample to sample, run to run, lot to lot, and user to user consistency. Conceptually very similar to a real-time PCR reaction, the LAS platform iteratively flows small volumes of sample and labeled detection antibodies across the protein microarray (housed on Inanovate’s fluidic cartridges) and fluorescently measures the formation of the sandwich between capture antibody, analyte of interest, and detection antibody in real-time.
Due to the time-resolved nature of the assay, the resulting data is a rate of reaction, instead of a simple final fluorescent reading. This ‘rate of reaction’ based analysis helps deliver the following core advantages of LAS technology, each of which has been demonstrated through the development and validation of a five-plex assay consisting of CRP, IL-6, IL-1a, IL-8 and IL-1b.
1. Large detection range: LAS enables the accurate quantitation of protein concentrations across a 7 log range in a single multiplex test. This eliminates the need for serial dilutions, making multiplexing faster, cheaper and helping preserve precious samples.
2. Multiplexing flexibility: Due to its large detection range, LAS allows users to run virtually any assay of interest in one test, enabling the development of biologically relevant multiplexes.
3. Improved accuracy: LAS produces and analyses real-time kinetic data on protein interactions (rate of reaction data), improving identification and discrimination of background and nonspecific signals, delivering more accurate quantitation at low analyte concentrations.
LAS technology holds the potential to become to proteomics what PCR was to genomics. It offers a new approach to multiplexed protein screening that helps address many of the problems presently affecting the utility of biochips in protein biomarker discovery, validation and clinical screening applications. The Poster will both summarize the technical components of the new LAS based platform and present data from the five-plex demonstration work plus recent work on serology assays.

Abstract
INTRODUCTION Tumors of the parotid gland in children are rare and very little data has been published regarding the incidence of these tumors. We present a nationwide survey on this topic. METHODS Data regarding benign and malignant tumors in the parotid gland in children from January 1st, 1990 to December 31st, 2005 in Denmark was collected retrospectively from nationwide registries. This generated 61 patients for inclusion in this study. RESULTS 85% of the tumors were benign and the malignant tumors made up the last 15%. The most common of the malignant tumors was the acinic cell carcinoma (n=4) followed by the mucoepidermoid carcinoma (n=3) and adenoid cystic carcinoma (n=2). The overall female-to-male ratio was 1.18, with a ratio of 1.08 and 2.0 in the benign and malignant groups, respectively. At the end of follow-up (August 1st, 2014) two patients had died, one with adenoid cystic carcinoma and one with mucoepidermoid carcinoma. Both patients had perineural invasion and involved resection margins at presentation. The incidence was 0.12 and 0.53 per 100,000 children of the malignant and benign tumors, respectively. CONCLUSION Pleomorphic adenomas were the predominant neoplasm in the parotid gland in children. The most frequent of the malignant tumors was the acinic cell carcinoma, which is in contrast to previous studies. The proportion of malignant-to-benign parotid gland tumors is in contrast to earlier study reports not higher in children than in adults.

Abstract
This article explores the main elements of the Mental Capacity Act 2005 and the implications for nurses. Many vulnerable adults have impaired capacity, and it is vital that nurses are confident in understanding when and how to assess an individual's capacity. Nurses should be supported and given training to ensure they can apply the principles of the Mental Capacity Act 2005 to practice. It is also important that nurses have a good understanding of the deprivation of liberty safeguards and can identify when their interventions may deprive patients of their liberty, ensuring that these are only undertaken legally.

Abstract
Pre-registration students are bound by the Nursing and Midwifery Council's code of conduct, and must meet the expectations for performance laid out in the NMC's standards for competence. When a student is not achieving the relevant competencies and is regarded as at risk of failing a clinical placement, it is paramount that the mentor acts promptly, bringing forward interim interviews where appropriate. Good interview technique will help mentors and students to address difficulties in placements. Mentors should receive adequate support to address problems during the remainder of the student's placement or, if a student does not reach the required level of competency or professional behaviour, ensure that they do not pass.
