Abstract

The objective of this study was to compare the effectiveness of a second tumor necrosis factor inhibitor (TNFi) versus a non‐TNFi biologic following discontinuation of a TNFi for patients with polyarticular‐course juvenile idiopathic arthritis (pJIA). Using the Childhood Arthritis and Rheumatology Research Alliance Registry, patients with pJIA who started receiving a second biologic following a first TNFi were identified. Patients were required to have no active uveitis on the index date and a visit six months after the index date. Outcome measures included Clinical Juvenile Arthritis Disease Activity Score with a maximum of 10 active joints (cJADAS10), cJADAS10 inactive disease (ID; ≤2.5) and cJADAS10 minimal disease activity (MiDA; ≤5). Multiple imputation was used to account for missing data. Adjusted odds ratios (aORs) were calculated using propensity score quintiles to compare outcomes at six months following second biologic initiation. There were 216 patients included, 84% initially received etanercept, and most patients stopped receiving it because of its ineffectiveness (74%). A total of 183 (85%) started receiving a second TNFi, and 33 (15%) started receiving a non‐TNFi. Adalimumab was the most common second biologic received (71% overall, 84% of second TNFi), and tocilizumab was the most common non‐TNFi second biologic received (9% overall, 58% of non‐TNFi). There was no difference between receiving TNFi versus non‐TNFi in cJADAS10 ID (29% vs 25%; aOR 1.23, 95% confidence interval [CI] 0.47–3.20) or at least MiDA (43% vs 39%; aOR 1.11, 95% CI 0.47–2.62) at six months. Most patients with pJIA started receiving TNFi rather than non‐TNFi as their second biologic, and there were no differences in disease activity at six months.

8. Tear Proteins Altered in Patients with Persistent Eye Pain after Refractive Surgery: Biomarker Candidate Discovery

Author

Harkness, Brooke M., Chen, Siting, Kim, Kilsun, Reddy, Ashok P., McFarland, Trevor J., Hegarty, Deborah M., Everist, Steven J., Saugstad, Julie A., Lapidus, Jodi, Galor, Anat, and Aicher, Sue A.

Abstract

Some patients develop persistent eye pain after refractive surgery, but factors that cause or sustain pain are unknown. We tested whether tear proteins of patients with pain 3 months after surgery differ from those of patients without pain. Patients undergoing refractive surgery (laser in situ keratomileusis or photorefractive keratectomy ) were recruited from 2 clinics, and tears were collected 3 months after surgery. Participants rated their eye pain using a numerical rating scale (NRS, 0–10; no pain–worst pain) at baseline, 1 day, and 3 months after surgery. Using tandem mass tag proteomic analysis, we examined tears from patients with pain [NRS ≥ 3 at 3 months (n= 16)] and patients with no pain [NRS ≤ 1 at 3 months (n= 32)] after surgery. A subset of proteins (83 of 2748 detected, 3.0%) were associated with pain 3 months after surgery. High-dimensional statistical models showed that the magnitude of differential expression was not the only important factor in classifying tear samples from pain patients. Models utilizing 3 or 4 proteins had better classification performance than single proteins and represented differences in both directions (higher or lower in pain). Thus, patterns of protein differences may serve as biomarkers of postsurgical eye pain as well as potential therapeutic targets.

13. Proteomic changes induced by longevity-promoting interventions in mice

Author

Burns, Adam R., Wiedrick, Jack, Feryn, Alicia, Maes, Michal, Midha, Mukul K., Baxter, David H., Morrone, Seamus R., Prokop, Timothy J., Kapil, Charu, Hoopmann, Michael R., Kusebauch, Ulrike, Deutsch, Eric W., Rappaport, Noa, Watanabe, Kengo, Moritz, Robert L., Miller, Richard A., Lapidus, Jodi A., and Orwoll, Eric S.

Abstract

Using mouse models and high-throughput proteomics, we conducted an in-depth analysis of the proteome changes induced in response to seven interventions known to increase mouse lifespan. This included two genetic mutations, a growth hormone receptor knockout (GHRKOmice) and a mutation in the Pit-1locus (Snell dwarf mice), four drug treatments (rapamycin, acarbose, canagliflozin, and 17α-estradiol), and caloric restriction. Each of the interventions studied induced variable changes in the concentrations of proteins across liver, kidney, and gastrocnemius muscle tissue samples, with the strongest responses in the liver and limited concordance in protein responses across tissues. To the extent that these interventions promote longevity through common biological mechanisms, we anticipated that proteins associated with longevity could be identified by characterizing shared responses across all or multiple interventions. Many of the proteome alterations induced by each intervention were distinct, potentially implicating a variety of biological pathways as being related to lifespan extension. While we found no protein that was affected similarly by every intervention, we identified a set of proteins that responded to multiple interventions. These proteins were functionally diverse but tended to be involved in peroxisomal oxidation and metabolism of fatty acids. These results provide candidate proteins and biological mechanisms related to enhancing longevity that can inform research on therapeutic approaches to promote healthy aging.

17. Crystal structure and synchrotron X-ray powder reference pattern for the porous pillared cyanonickelate, Ni(3-amino-4,4′-bipyridine)[Ni(CN)4]

Author

Wong-Ng, W., Culp, J., Kaduk, J.A., Chen, Y.S., and Lapidus, S.

Abstract

The structure of Ni(3-amino-4,4′-bipyridine)[Ni(CN)4] (or known as Ni-BpyNH2) in powder form was determined using synchrotron X-ray diffraction and refined using the Rietveld refinement technique (R= 8.8%). The orthorhombic (Cmca) cell parameters were determined to be a= 14.7218(3) Å, b= 22.6615(3) Å, c= 12.3833(3) Å, V= 4131.29(9) Å3, and Z= 8. Ni-BpyNH2forms a 3-D network, with a 2-D Ni(CN)4net connecting to each other via the BpyNH2ligands. There are two independent Ni sites on the net. The 2-D nets are connected to each other via the bonding of the pyridine “N” atom to Ni2. The Ni2 site is of six-fold coordination to N with relatively long Ni2–N distances (average of 2.118 Å) as compared to the four-fold coordinated Ni1–C distances (average of 1.850 Å). The Ni(CN)4net is arranged in a wave-like fashion. The functional group, –NH2, is disordered and was found to be in the m-position relative to the N atom of the pyridine ring. Instead of having a unique position, N has ¼ site occupancy in each of the four m-positions. The powder reference diffraction pattern for Ni-BpyNH2was prepared and submitted to the Powder Diffraction File (PDF) at the International Centre of Diffraction Data (ICDD).

Abstract

During the pandemic period, health care systems were substantially reorganized for managing COVID-19 cases. Corresponding consequences on persons with chronic diseases remain insufficiently documented. This observational cohort study investigated the direct and indirect impact of the pandemic period on the survival of kidney transplant recipients (KTR). Using the French National Health Data System, incident persons with end-stage kidney disease between 2015 and 2020, and who received a kidney transplant during this period were included and followed up from their transplantation date to December 31, 2021. The survival of KTR during the prepandemic and pandemic periods was investigated using Cox models with time-dependent covariates. There were 10 637 KTR included in the study, with 324 and 430 deaths observed during the prepandemic and pandemic periods, respectively. The adjusted risk of death during the pandemic period was similar to that observed during the prepandemic period (hazard ratio [HR] [95% confidence interval]: 0.92 [0.77-1.11]), COVID-19–related hospitalization was associated with an increased risk of death (HR: 10.62 [8.46-13.33]), and a third vaccine dose was associated with a lower risk of death (HR: 0.42 [0.30-0.57]). The pandemic period was not associated with an indirect higher risk of death in KTR with no COVID-19–related hospitalization.

19. Soft-Chemical Synthesis, Structure Evolution, and Insulator-to-Metal Transition in Pyrochlore-like λ-RhO2

Author

Abstract

λ-RhO2, a prototype 4d transition metal oxide, has been prepared by the oxidative delithiation of spinel LiRh2O4using ceric ammonium nitrate. Average-structure studies of this RhO2polytype, including synchrotron powder X-ray diffraction and electron diffraction, indicate the room-temperature structure to be tetragonal, in space group I41/amd, with a first-order structural transition to cubic Fd3̅mat T= 345 K on warming. Synchrotron X-ray pair distribution function analysis and 7Li solid-state nuclear magnetic resonance measurements suggest that the room-temperature structure displays local Rh–Rh bonding. The formation of these local dimers appears to be associated with a metal-to-insulator transition with a nonmagnetic ground state, as also supported by density functional theory-based electronic structure calculations. This contribution demonstrates the power of soft chemistry to kinetically stabilize a simple binary oxide compound.

20. Valuing the Economic Impact of River Floods and Early Flood Warning for Households in Bangladesh

Author

Zayed, Stephanie, Morrison, Laura T. R., Lapidus, Daniel, Gallaher, Michael, Letterman, Clark, Allpress, Justine L. E., and Cummings, Stirling

Abstract

Flood early warning systems have the potential to mitigate damages for vulnerable populations that experience river flooding in Bangladesh. We conducted a 2,247 household survey and series of focus groups to estimate the economic damages from 2016 river floods and the hypothetical savings of a 3- and 8-day warning for households living in the Jamuna River floodplain. Households were identified using geo-sampling, a novel geographic information system (GIS)–based sampling methodology that facilitates probability-based sampling where data are insufficient. Total damages for the entire flood plain in 2016 totaled to $1.3 billion, or 25% of household income and assets. Respondents estimated avoided damages from a hypothetical 3- and 8-day warning to be $73m and $85m, respectively, reflecting diminishing returns to additional days of early warning. With the hypothetical early warning, respondents derived the greatest savings from protecting their land, household/dwelling, and livestock. The greatest savings to households receiving a hypothetical additional 5 days of warning (from a 3- to an 8-day warning) would be realized in protecting agricultural production. Selling assets/livestock and employing protective sandbags were the preventative actions with the highest benefit–cost ratios that households said they would undertake. Importantly, only 11% of households received any early warning at all during the 2016 flood season, suggesting that the greatest benefits moving forward would be achieved by communicating existing or improved warnings more effectively to households in the floodplain.

21. The relationship between 11 different polygenic longevity scores, parental lifespan, and disease diagnosis in the UK Biobank

Abstract

Large-scale genome-wide association studies (GWAS) strongly suggest that most traits and diseases have a polygenic component. This observation has motivated the development of disease-specific “polygenic scores (PGS)” that are weighted sums of the effects of disease-associated variants identified from GWAS that correlate with an individual’s likelihood of expressing a specific phenotype. Although most GWAS have been pursued on disease traits, leading to the creation of refined “Polygenic Risk Scores” (PRS) that quantify risk to diseases, many GWAS have also been pursued on extreme human longevity, general fitness, health span, and other health-positive traits. These GWAS have discovered many genetic variants seemingly protective from disease and are often different from disease-associated variants (i.e., they are not just alternative alleles at disease-associated loci) and suggest that many health-positive traits also have a polygenic basis. This observation has led to an interest in “polygenic longevity scores (PLS)” that quantify the “risk” or genetic predisposition of an individual towards health. We derived 11 different PLS from 4 different available GWAS on lifespan and then investigated the properties of these PLS using data from the UK Biobank (UKB). Tests of association between the PLS and population structure, parental lifespan, and several cancerous and non-cancerous diseases, including death from COVID-19, were performed. Based on the results of our analyses, we argue that PLS are made up of variants not only robustly associated with parental lifespan, but that also contribute to the genetic architecture of disease susceptibility, morbidity, and mortality.

Abstract

Health disparities in childhood‐onset systemic lupus erythematosus (SLE) disproportionately impact marginalized populations. Socioeconomically patterned missing data can magnify existing health inequities by supporting inferences that may misrepresent populations of interest. Our objective was to assess missing data and subsequent health equity implications among participants with childhood‐onset SLE enrolled in a large pediatric rheumatology registry. We evaluated co‐missingness of 12 variables representing demographics, socioeconomic position, and clinical factors (e.g., disease‐related indices) using Childhood Arthritis and Rheumatology Research Alliance Registry childhood‐onset SLE enrollment data (2015–2022; n = 766). We performed logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) for missing disease‐related indices at enrollment (Systemic Lupus Erythematosus Disease Activity Index 2000 [SLEDAI‐2K] and/or Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index [SDI]) associated with data missingness. We used linear regression to assess the association between socioeconomic factors and SLEDAI‐2K at enrollment using 3 analytic methods for missing data: complete case analysis, multiple imputation, and nonprobabilistic bias analyses, with missing values imputed to represent extreme low or high disadvantage. On average, participants were missing 6.2% of data, with over 50% of participants missing at least 1 variable. Missing data correlated most closely with variables within data categories (i.e., demographic). Government‐assisted health insurance was associated with missing SLEDAI‐2K and/or SDI scores compared to private health insurance (OR 2.04 [95% CI 1.22, 3.41]). The different analytic approaches resulted in varying analytic sample sizes and fundamentally conflicting estimated associations. Our results support intentional evaluation of missing data to inform effect estimate interpretation and critical assessment of causal statements that might otherwise misrepresent health inequities.

36. Spin-mediated shear oscillators in a van der Waals antiferromagnet

Abstract

Understanding how microscopic spin configuration gives rise to exotic properties at the macroscopic length scale has long been pursued in magnetic materials1–5. One seminal example is the Einstein–de Haas effect in ferromagnets1,6,7, in which angular momentum of spins can be converted into mechanical rotation of an entire object. However, for antiferromagnets without net magnetic moment, how spin ordering couples to macroscopic movement remains elusive. Here we observed a seesaw-like rotation of reciprocal lattice peaks of an antiferromagnetic nanolayer film, whose gigahertz structural resonance exhibits more than an order-of-magnitude amplification after cooling below the Néel temperature. Using a suite of ultrafast diffraction and microscopy techniques, we directly visualize this spin-driven rotation in reciprocal space at the nanoscale. This motion corresponds to interlayer shear in real space, in which individual micro-patches of the film behave as coherent oscillators that are phase-locked and shear along the same in-plane axis. Using time-resolved optical polarimetry, we further show that the enhanced mechanical response strongly correlates with ultrafast demagnetization, which releases elastic energy stored in local strain gradients to drive the oscillators. Our work not only offers the first microscopic view of spin-mediated mechanical motion of an antiferromagnet but it also identifies a new route towards realizing high-frequency resonators8,9up to the millimetre band, so the capability of controlling magnetic states on the ultrafast timescale10–13can be readily transferred to engineering the mechanical properties of nanodevices.

37. Interplanar Ferromagnetism Enhanced Ultrawide Zero Thermal Expansion in Kagome Cubic Intermetallic (Zr,Nb)Fe2

Abstract

A cubic metal exhibiting zero thermal expansion (ZTE) over a wide temperature window demonstrates significant applications in a broad range of advanced technologies but is extremely rare in nature. Here, enabled by high-temperature synthesis, we realize tunable thermal expansion via magnetic doping in the class of kagome cubic (Fd-3m) intermetallic (Zr,Nb)Fe2. A remarkably isotropic ZTE is achieved with a negligible coefficient of thermal expansion (+0.47 × 10–6K–1) from 4 to 425 K, almost wider than most ZTE in metals available. A combined in situ magnetization, neutron powder diffraction, and hyperfine Mössbauer spectrum analysis reveals that interplanar ferromagnetic ordering contributes to a large magnetic compensation for normal lattice contraction upon cooling. Trace Fe-doping introduces extra magnetic exchange interactions that distinctly enhance the ferromagnetism and magnetic ordering temperature, thus engendering such an ultrawide ZTE. This work presents a promising ZTE in kagome metallic materials.

39. Electrochemical Control of Magnetism on the Breathing Kagome Network of LixScMo3O8

Abstract

Controlling properties within a given functional inorganic material structure type is often accomplished through tuning the electronic occupation, which is in turn dictated by the elemental composition determined at the time of material preparation. We employ electrochemical control of the lithium content, with associated electronic occupancy control, to vary the magnetic properties of a material where a kagome-derived network of Mo3triangles carry the spin. In this case, Li is electrochemically inserted into LiScMo3O8, a layered compound containing a breathing Mo kagome network. Up to two additional Li can be inserted into LiScMo3O8, transforming it into Li3ScMo3O8. Li2ScMo3O8prepared by electrochemical lithiation is compared to the quantum spin liquid candidate compound Li2ScMo3O8prepared through high-temperature solid-state methods, which has a slightly different structural stacking sequence but a similar kagome-derived network. Magnetic measurements are supported by first-principles calculations, showing that electrons remain localized on the Mo clusters throughout the doping series. As xis varied in LixScMo3O8, the measurements and calculations reveal the evolution from a diamagnetic band insulator at x= 1 to a geometrically frustrated magnet at x= 2, back to a diamagnetic insulator at x= 3. These results indicate a likelihood of strong coupling between the degree of Li disorder and charge/magnetic ordering over the Mo3clusters.

Abstract

The goal was to characterize short‐term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood‐onset systemic lupus erythematosus (cSLE) and nephritis. We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy‐proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. We identified 222 patients with kidney biopsy–proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8–29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21–12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01–1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short‐term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long‐term kidney outcomes.

42. Patterns of Daily Life. IREX Occasional Papers, Volume 1, Number 4.

Author

International Research and Exchange Board, New York, NY., Cole, John W., and Lapidus, Gail Warshofsky

Abstract

Two papers are presented which were originally prepared for delivery at a conference to evaluate the results of 20 years of scholarly exchange between the United States, the USSR, and Eastern Europe. Participants included over 300 members of the public affairs community, including government officials, public policy makers, business leaders, journalists, and educators. Both papers deal with the daily life of Eastern European Citizens. In the first paper, "In a Pig's Eye: Daily Life and Political Economy in Southeastern Europe," by John W. Cole, emphasis is placed on the necessity of viewing Southeastern European culture in terms of its own past experience and in comparison with other agrarian areas rather than in comparison with Western Europe or the United States. Southeastern Europe is characterized as an agrarian society undergoing industrialization and urbanization. In most cases, the most intensive social and economic ties are between parents and their offspring, although there are also important links among village households. In the second paper, "Studying the Soviet Social System: The 'Soviet Citizen' Revisited," author Gail Warshofsky Lapidus focuses on the importance of and changes which have occurred since publication of the original "Soviet Citizen" (by Alex Inkeles and Raymond Bauer, Harvard University Press) in 1959. The author concludes that scholars will be able to produce new research as insightful as the "Soviet Citizen" if they are allowed to undertake social science research in outlying regions of the USSR, make an effort to conceptualize societal differences between the United States and the USSR through some other prism than the 'industrial society' model, and if they disseminate research findings in academic and governmental communities.

43. Doctoral Education: Preparing for the Future.

Author

Council of Graduate Schools, Washington, DC. and LaPidus, Jules B.

Abstract

This monograph notes the dichotomy between doctoral education and preparation for various kinds of jobs or careers, arguing that while doctoral education prepares people to do independent research, employers by and large are seeking other skills. This paper attempts to examine the role of graduate education through a variety of lenses--e.g., as preparation for a career in research, preparation for scholarship, for faculty positions, for industrial positions, for professional practice, for other positions, and for life. It sees preparation for research as a vehicle for preparing scholars, and it defines scholarship as seeing one's research within a larger framework of intellectual work. In considering preparation for faculty positions the paper notes that more attention must be placed on training teaching assistants for the full range of faculty work. And for industrial careers, it argues for programs analogous to internships in teaching hospitals. In advocating preparation for life, the paper asks how far graduate programs should go to prepare students for life, and suggests workshops and seminars to provide practical skills in areas such as preparing resumes, time management, and working in teams. Finally, the paper offers some examples of approaches being tried on various campuses to broaden graduate education. (Contains 20 references.) (CH)

Abstract

Human tears contain abundant, diverse sets of proteins that may serve as biomarkers of ocular surface health. There is a need for reproducible methods that consider multiple factors influencing the tear proteome, in addition to the variable of interest. Here we examined a workflow for proteomic analysis of tear proteins without the need to pool tear samples from multiple individuals, thus allowing for analyses based on individual factors, and increasing opportunities for protein biomarker discovery.

Abstract

Children with well‐controlled juvenile idiopathic arthritis (JIA) frequently experience flares after medication discontinuation, but the outcomes of these flares have not been well described. The objective of this study was to characterize the rates and predictors of disease recapture among children with JIA who restarted medication to treat disease flare. Children with JIA who discontinued conventional synthetic or biologic disease‐modifying antirheumatic drugs for well‐controlled disease but subsequently experienced a flare and restarted medication were identified from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) registry. The primary outcome was inactive disease (ID) (physician global assessment <1 and active joint count = 0) 6 months after flare. A total of 333 patients had complete data for ID at 6 months after flare. The recapture rate for the cohort was 55%, ranging from 47% (persistent oligoarthritis) to 69% (systemic arthritis) (P= 0.4). Approximately 67% of children achieved ID by 12 months. In the multivariable model, history and reinitiation of biologic drugs were associated with increased odds of successful recapture (odds ratio [OR] 4.79 [95% confidence interval (95% CI) 1.22–18.78] and OR 2.74 [95% CI 1.62–4.63], respectively). Number of joints with limited range of motion was associated with decreased odds (OR 0.83 per 1 joint increase [95% CI 0.72–0.95]). Approximately half of JIA flares post‐discontinuation were recaptured within 6 months, but rates of recapture varied across JIA categories. These findings inform shared decision‐making for patients, families, and clinicians regarding the risks and benefits of medication discontinuation. Better understanding of biologic predictors of successful recapture in JIA are needed.

48. The Instrumented Stand and Walk (ISAW) test to predict falls in older men

Abstract

Objective measures of balance and gait have the potential to improve prediction of future fallers because balance and gait impairments are common precursors. We used the Instrumented Stand and Walk Test (ISAW) with wearable, inertial sensors to maximize the domains of balance and gait evaluated in a short test. We hypothesized that ISAW objective measures across a variety of gait and balance domains would improve fall prediction beyond history of falls and better than gait speed or dual-task cost on gait-speed. We recruited 214 high-functioning older men (mean 82 years), of whom 91 participants (42.5%) had one or more falls in the 12 months following the ISAW test. The ISAW test involved 30 s of stance followed by a 7-m walk, turn, and return. We examined regression models for falling using 17 ISAW metrics, with and without age and fall history, and characterize top-performing models by AUC and metrics included. The ISAW test improved distinguishing between future fallers and non-fallers compared to age and history of falls, alone (AUC improved from 0.69 to 0.75). Models with 1 ISAW metric usually included a postural sway measure, models with 2 ISAW measures included a turning measure, models with 3 ISAW measures included a gait variability measure, and models with 4 or 5 measures added a gait initiation measure. Gait speed and dual-task cost did not distinguish between fallers and non-fallers in this high-functioning cohort. The best fall-prediction models support the notion that older people may fall due to a variety of balance and gait impairments.
