Maternal Cannabis Use during Lactation and Potential Effects on Human Milk Composition and Production: A Narrative Review.

Cannabis use has increased sharply in the last 20 y among adults, including reproductive-aged women. Its recent widespread legalization is associated with a decrease in risk perception of cannabis use during breastfeeding. However, the effect of cannabis use (if any) on milk production and milk composition is not known. This narrative review summarizes current knowledge related to maternal cannabis use during breastfeeding and provides an overview of possible pathways whereby cannabis might affect milk composition and production. Several studies have demonstrated that cannabinoids and their metabolites are detectable in human milk produced by mothers who use cannabis. Due to their physicochemical properties, cannabinoids are stored in adipose tissue, can easily reach the mammary gland, and can be secreted in milk. Moreover, cannabinoid receptors are present in adipocytes and mammary epithelial cells. The activation of these receptors directly modulates fatty acid metabolism, potentially causing changes in milk fatty acid profiles. Additionally, the endocannabinoid system is intimately connected to the endocrine system. As such, it is probable that interactions of exogenous cannabinoids with the endocannabinoid system might modify release of critical hormones (e.g., prolactin and dopamine) that regulate milk production and secretion. Nonetheless, few studies have investigated effects of cannabis use (including on milk production and composition) in lactating women. Additional research utilizing robust methodologies are needed to elucidate whether and how cannabis use affects human milk production and composition.

Photoplethysmography based atrial fibrillation detection: a continually growing field.

Objective. Atrial fibrillation (AF) is a prevalent cardiac arrhythmia associated with significant health ramifications, including an elevated susceptibility to ischemic stroke, heart disease, and heightened mortality. Photoplethysmography (PPG) has emerged as a promising technology for continuous AF monitoring for its cost-effectiveness and widespread integration into wearable devices. Our team previously conducted an exhaustive review on PPG-based AF detection before June 2019. However, since then, more advanced technologies have emerged in this field.Approach. This paper offers a comprehensive review of the latest advancements in PPG-based AF detection, utilizing digital health and artificial intelligence (AI) solutions, within the timeframe spanning from July 2019 to December 2022. Through extensive exploration of scientific databases, we have identified 57 pertinent studies.Significance. Our comprehensive review encompasses an in-depth assessment of the statistical methodologies, traditional machine learning techniques, and deep learning approaches employed in these studies. In addition, we address the challenges encountered in the domain of PPG-based AF detection. Furthermore, we maintain a dedicated website to curate the latest research in this area, with regular updates on a regular basis.

Cannabis use, decision making, and perceptions of risk among breastfeeding individuals: the Lactation and Cannabis (LAC) Study.

OBJECTIVE: Our primary objective was to understand breastfeeding individuals' decisions to use cannabis. Specifically, we investigated reasons for cannabis use, experiences with healthcare providers regarding use, and potential concerns about cannabis use. METHODS: We collected survey data from twenty breastfeeding participants from Washington and Oregon who used cannabis at least once weekly. We documented individuals' cannabis use and analyzed factors associated with their decisions to use cannabis during lactation. Qualitative description was used to assess responses to an open-ended question about potential concerns. RESULTS: Fifty-five percent of participants (n = 11) reported using cannabis to treat or manage health conditions, mostly related to mental health. Eighty percent of participants (n = 16) reported very few or no concerns about using cannabis while breastfeeding, although participants who used cannabis for medical purposes had significantly more concerns. Most participants (n = 18, 90%) reported receiving either no or unhelpful advice from healthcare providers. Four themes arose through qualitative analysis, indicating that breastfeeding individuals are: 1) identifying research gaps and collecting evidence; 2) monitoring their child's health and development; 3) monitoring and titrating their cannabis use; and 4) comparing risks between cannabis and other controlled substances. CONCLUSIONS: Breastfeeding individuals reported cannabis for medical and non-medical reasons and few had concerns about cannabis use during breastfeeding. Breastfeeding individuals reported using a variety of strategies and resources in their assessment of risk or lack thereof when deciding to use cannabis. Most participants reported receiving no helpful guidance from healthcare providers.

Correlates of COVID-19 Information Overload and Information Seeking: Evidence from a Community Survey.

PURPOSE: To examine the relationships among health literacy, risk perceptions, COVID-19 information overload, health information seeking, and race/ethnicity. DESIGN: A cross-sectional non-probability community survey conducted between December 2020 and January 2021. A questionnaire was developed in collaboration with a local minority health task force. SETTING: Albany, New York, USA. SAMPLE: 331 adults residing in Albany, NY and neighboring areas (80.3% completion rate). MEASURES: Multi-item scales were used to measure health literacy, perceived severity, perceived susceptibility, information overload, and health information seeking frequency and types. ANALYSIS: We conducted multivariate regression analysis. RESULTS: Health literacy (standardized ß = -.33, P < .001) and perceived severity (ß = -.23, P < .001) were negatively associated with information overload. Information overload was negatively associated with health information seeking frequency (ß = -.16, P < .05) and types (ß = -.19, P < .01). A further analysis shows several factors, including information overload and race (African Americans), were negatively related to seeking specific types of information. CONCLUSION: We find that low health literacy and perceived severity contribute to information overload and that information overload adversely affects health information seeking. Black individuals are less likely to search for certain types of information. The cross-sectional study design limits our ability to determine causality. Future research should employ panel data to determine the directionality of the observed relationships.

Breastfeeding patterns are associated with human milk microbiome composition: The Mother-Infant Microbiomes, Behavior, and Ecology Study (MIMBES).

The human milk microbiome (HMM) is hypothesized to be seeded by multiple factors, including the infant oral microbiome during breastfeeding. However, it is not known whether breastfeeding patterns (e.g., frequency or total time) impact the composition of the HMM. As part of the Mother-Infant Microbiomes, Behavior, and Ecology Study (MIMBES), we analyzed data from naturalistic observations of 46 mother-infant dyads living in the US Pacific Northwest and analyzed milk produced by the mothers for its bacterial diversity and composition. DNA was extracted from milk and the V1-V3 region of the 16S rRNA gene was amplified and sequenced. We hypothesized that number of breastfeeding bouts (breastfeeding sessions separated by >30 seconds) and total time breastfeeding would be associated with HMM α-diversity (richness, diversity, or evenness) and differential abundance of HMM bacterial genera. Multiple linear regression was used to examine associations between HMM α-diversity and the number of breastfeeding bouts or total time breastfeeding and selected covariates (infant age, maternal work outside the home, frequency of allomother physical contact with the infant, non-household caregiving network). HMM richness was inversely associated with number of breastfeeding bouts and frequency of allomother physical contact, but not total time breastfeeding. Infants' non-household caregiving network was positively associated with HMM evenness. In two ANCOM-BC analyses, abundances of 5 of the 35 most abundant genera were differentially associated with frequency of breastfeeding bouts (Bifidobacterium, Micrococcus, Pedobacter, Acidocella, Achromobacter); 5 genera (Bifidobacterium, Agreia, Pedobacter, Rugamonas, Stenotrophomonas) were associated with total time breastfeeding. These results indicate that breastfeeding patterns and infant caregiving ecology may play a role in influencing HMM composition. Future research is needed to identify whether these relationships are consistent in other populations and if they are associated with variation in the infant's gastrointestinal (including oral) microbiome.

Maternal-infant interaction quality is associated with child NR3C1 CpG site methylation at 7 years of age.

OBJECTIVE: Infancy is both a critical window for hypothalamic-pituitary-adrenal (HPA) axis development, and a sensitive period for social-emotional influences. We hypothesized that the social-emotional quality of maternal-infant interactions are associated with methylation of HPA-axis gene NR3C1 later in childhood. METHODS: Using a subsample of 114 mother-infant pairs from the Avon Longitudinal Study of Parents and Children (ALSPAC), linear regression models were created to predict variance in methylation of seven selected CpG sites from NR3C1 in whole blood at age 7 years, including the main predictor variable of the first principal component score of observed maternal-infant interaction quality (derived from the Thorpe Interaction Measure at 12 months of age) and covariates of cell-type proportion, maternal financial difficulties and marital status at 8 months postnatal, child birthweight, and sex. RESULTS: CpG site cg27122725 methylation was negatively associated with warmer, more positive maternal interaction with her infant (ß = 0.19, p = .02, q = 0.13). In sensitivity analyses, the second highest quartile of maternal behavior (neutral, hesitant behavior) was positively associated with cg12466613 methylation. The other five CpG sites were not significantly associated with maternal-infant interaction quality. CONCLUSIONS: Narrow individual variation of maternal interaction with her infant is associated with childhood methylation of two CpG sites on NR3C1 that may be particularly sensitive to environmental influences. Infancy may be a sensitive period for even small influences from the social-emotional environment on the epigenetic determinants of HPA-axis function.

Impact of key manifestations of psoriatic arthritis on patient quality of life, functional status, and work productivity: Findings from a real-world study in the United States and Europe.

OBJECTIVES: To determine the individual impact of key manifestations of psoriatic arthritis (PsA) on quality of life (QoL), physical function, and work disability. METHODS: Data from the Adelphi 2018 PsA Disease-Specific Programme, a multinational, cross-sectional study of PsA patients, were used. PsA manifestations included peripheral arthritis (number of joints affected), psoriasis (body surface area [BSA]), axial involvement (inflammatory back pain [IBP] and sacroiliitis) enthesitis, and dactylitis. General, and disease-specific QoL, physical function, and work disability were measured with EQ-5D-5L, PsAID-12, HAQ-DI, and WPAI, respectively. Multivariate regression adjusting for potential confounders evaluated the independent effect of PsA manifestations on each outcome. RESULTS: Among the 2222 PsA patients analysed, 77.0% had active psoriasis and 64.4% had peripheral arthritis; 5.9%, 6.8%, 10.2%, and 3.6% had enthesitis, dactylitis, IBP, or sacroiliitis, respectively. Mean EQ VAS scores were significantly poorer in patients with vs. without enthesitis (59.9 vs. 75.6), dactylitis (63.6 vs. 75.4), and with greater peripheral joint involvement (none: 82.5; 1-2 affected joints: 74.1; 3-6 joints: 74.2; >6 joints: 65.0). Significantly worse mean PsAID-12 scores were associated with vs. without enthesitis (4.39 vs. 2.34) or dactylitis (4.30 vs. 2.32), and with greater peripheral joint involvement (none: 1.21; 1-2 joints: 2.36; 3-6 joints: 2.74; >6 joints: 3.92), and BSA (none: 1.49; >3-10%: 2.96; >10%: 3.43). Similar patterns were observed with HAQ-DI and WPAI scores. CONCLUSION: Most PsA manifestations were independently associated with worse general, and PsA-specific QoL, physical function, and work disability, highlighting the need for treatments targeting the full spectrum of PsA symptoms to lower the burden of disease.

Impact of Physician-Defined Flares on Quality of Life and Work Impairment: An International Survey of 2238 Patients With Psoriatic Arthritis.

OBJECTIVE: To describe psoriatic arthritis (PsA) flares and their effect on patient-reported outcomes (PROs). METHODS: Cross-sectional surveys of rheumatologists/dermatologists and their patients with PsA were conducted in France, Germany, Italy, Spain, the United Kingdom, and the United States, capturing data on physician-reported patient flare status, demographics, PsA severity, and clinical outcomes. Patient-completed surveys captured data on PROs: 5-level EuroQol 5-dimension, Work Productivity and Activity Impairment questionnaire, Health Assessment Questionnaire-Disability Index, and 12-item Psoriatic Arthritis Impact of Disease questionnaire. Patients were compared by flare status using parametric and nonparametric tests. Multivariate regression was used to identify flare associations. Multivariate logistic regression adjusted for patient demographics and physician specialty assessed the effect of flare status. RESULTS: Among 2238 patients (586 from the US, 1652 from Europe) managed by 572 physicians, physician-reported flare was present for 168 patients (7.5%), and self-reported flare was present for 95 patients (10% of available data). Mean (SD) flare count over 12 months was 2.2 (4.9), lasting on average 16.4 (16.2) days. Flare status was linked to worse PROs. Patients who had not flared in the last 12 months or had never flared had a higher quality of life, lower overall work impairment, and a lower degree of disability compared with patients who were currently experiencing a flare (all; P < 0.01). CONCLUSION: Actively experiencing a flare adversely affected QOL, disability, and work productivity. PsA flares should be routinely assessed and managed in clinical care.

Women With Psoriatic Arthritis Experience Higher Disease Burden Than Men: Findings From a Real-World Survey in the United States and Europe.

OBJECTIVE: Although psoriatic arthritis (PsA) is equally present in men and women, sex may influence clinical manifestations and the impact of disease on patients' lives. This study assessed differences in clinical characteristics, disability, quality of life (QOL), and work productivity by sex in real-world practice. METHODS: A cross-sectional survey of rheumatologists/dermatologists and their patients with PsA was conducted in France, Germany, Italy, Spain, the United Kingdom, and the United States between June and August 2018. Data collected included demographics, treatment use, clinical characteristics (tender joint count, swollen joint count, body surface area affected by psoriasis), QOL (EuroQoL 5-Dimension questionnaire [EQ-5D], Psoriatic Arthritis Impact of Disease [PsAID12]), disability (Health Assessment Questionnaire-Disability Index [HAQ-DI]), and work productivity (Work Productivity and Impairment Index [WPAI]). Outcomes were compared between men and women using parametric and nonparametric tests, as appropriate. RESULTS: Of 2270 patients (mean age 48.6 [SD 13.3] yrs, mean disease duration 4.9 [SD 6.0] yrs), 1047 (46.1%) were women. Disease duration, disease presentation, and biologic use (mean 54.2%) were comparable between women and men. Women reported worse QOL (EQ-5D: 0.80 [SD 0.2] vs 0.82 [SD 0.2]; P = 0.02), greater disability (HAQ-DI: 0.56 [SD 0.6] vs 0.41 [SD 0.5]; P < 0.01) and work activity impairment (WPAI: 27.9% [SD 22.0] vs 24.6% [SD 22.4]; P < 0.01) than men. However, women had a lower burden of comorbidities (Charlson Comorbidity Index: 1.10 [SD 0.5] vs 1.15 [SD 0.6]; P < 0.01). CONCLUSION: In patients with similar PsA disease activity and treatment, women experienced greater disease impact than men. This represents a significant consideration for the therapeutic management of PsA.

Effect of Fatigue on Health-Related Quality of Life and Work Productivity in Psoriatic Arthritis: Findings From a Real-World Survey.

OBJECTIVE: To evaluate fatigue frequency and severity among patients with psoriatic arthritis (PsA) and assess the effect of fatigue severity on patient-reported outcome measures (PROMs) assessing quality of life, function, and work productivity. METHODS: Data were derived from the Adelphi Disease Specific Programme, a cross-sectional survey conducted in 2018 in the United States and Europe. Patients had physician-confirmed PsA. Fatigue was collected as a binary variable and through its severity (0-10 scale, using the 12-item Psoriatic Arthritis Impact of Disease fatigue question) from patients; physicians also reported patient fatigue (yes/no). Other PROMs included the 5-level EuroQol 5-dimension questionnaire (EQ-5D-5L) for health-related quality of life (HRQOL), Health Assessment Questionnaire-Disability Index, and Work Productivity and Activity Impairment Questionnaire. Multivariate linear regression was used to evaluate the association between fatigue severity and other PROMs. RESULTS: Among the 831 included patients (mean age 47.5 yrs, mean disease duration 5.3 yrs, 46.9% female, 48.1% receiving a biologic), fatigue was reported by 78.3% of patients. Patients with greater fatigue severity had greater disease duration, PsA severity, pain levels, body surface area affected by psoriasis, and swollen and tender joint counts (all P < 0.05). In multivariate analyses, patients with greater fatigue severity experienced worse physical functioning, HRQOL, and work productivity (all P < 0.001). Presence of fatigue was underreported by physicians (reported in only 32% of patients who self-reported fatigue). CONCLUSION: Prevalence of patient-reported fatigue was high among patients with PsA and underrecognized by physicians. Fatigue severity was associated with altered physical functioning, work productivity, and HRQOL.

Maternal depression and adverse neighbourhood conditions during pregnancy are associated with gestational epigenetic age deceleration.

Gestational epigenetic age (GEA) acceleration and deceleration can indicate developmental risk and may help elucidate how prenatal exposures lead to offspring outcomes. Depression and neighbourhood conditions during pregnancy are well-established determinants of birth and child outcomes. Emerging research suggests that maternal depression may contribute to GEA deceleration. It is unknown whether prenatal neighbourhood adversity would likewise influence GEA deceleration. This study examined whether maternal depression and neighbourhood conditions independently or jointly contributed to GEA deceleration, and which social and environmental neighbourhood conditions were associated with GEA. Participants were from the Albany Infant and Mother Study (n = 204), a prospective non-probability sampled cohort of higher risk racial/ethnic diverse mother/infant dyads. GEA was estimated from cord blood. Depressive symptoms and census-tract level neighbourhood conditions were assessed during pregnancy. Maternal depression (ß = -0.03, SE = 0.01, p = 0.008) and neighbourhood adversity (ß = -0.32, SE = 0.14, p = 0.02) were independently associated with GEA deceleration, controlling for all covariates including antidepressant use and cell type proportions. Neighbourhood adversity did not modify the association of maternal depression and GEA (ß = 0.003, SE = 0.03, p = 0.92). igher levels of neighbourhood poverty, public assistance, and lack of healthy food access were each associated with GEA deceleration; higher elementary school test scores (an indicator of community tax base) were associated with GEA acceleration (all p < 0.001). The results of this study indicated that maternal depression and neighbourhood conditions were independently and cumulatively associated GEA in this diverse population.

#Hackademics: Hacks toward success in academia.

OBJECTIVE: The Sausage of Science is a podcast for the Human Biology Association and the American Journal of Human Biology through which we introduced a special series called #Hackademics. The podcast was initially used to highlight the scholarship and humanity of fellow human biologists through interviews about "how the sausage is made" in research-that is, the nuts and bolts that go into our publications. However, we soon realized there is much more a weekly podcast can do to help colleagues in our interrelated fields. METHODS: Here we introduce the different contributions to this #Hackdemics special issue. Through #Hackademics, we address under-discussed topics in academia such as work-life integration, hostile academic environments, decolonization of research and teaching, and science communication, among others. RESULTS: The feedback received from listeners for the #Hackademics series reinforced a need for more tools for navigating the academic side of our disciplines. Furthermore, there was a need to decentralize what is often termed "institutional knowledge" by sharing it in a more authoritative medium-a special issue of peer-reviewed articles in our Association's esteemed journal. This special issue's contributions also elevate diverse voices with multiple authors at different career stages. CONCLUSIONS: Using the institutional credibility of peer-review to legitimize these topics, this issue's articles can be a resource for those looking to initiate conversations or change within their departments or institutions with the hope of creating a kinder, more respectful, collaborative, equitable, and accessible academic environment.

Prenatal Lead and Depression Exposures Jointly Influence Birth Outcomes and NR3C1 DNA Methylation.

Many gestational exposures influence birth outcomes, yet the joint contribution of toxicant and psychosocial factors is understudied. Moreover, associated gestational epigenetic mechanisms are unknown. Lead (Pb) and depression independently influence birth outcomes and offspring NR3C1 (glucocorticoid receptor) DNA methylation. We hypothesized that gestational Pb and depression would jointly influence birth outcomes and NR3C1 methylation. Pregnancy exposure information, DNA methylation, and birth outcome data were collected prospectively from n = 272 mother-infant pairs. Factor analysis was used to reduce the dimensionality of NR3C1. Multivariable linear regressions tested for interaction effects between gestational Pb and depression exposures with birth outcomes and NR3C1. Interaction effects indicated that higher levels of Pb and depression jointly contributed to earlier gestations, smaller infant size at birth, and asymmetric fetal growth. Pb and depression were also jointly associated with the two primary factor scores explaining the most variability in NR3C1 methylation; NR3C1 scores were associated with some infant outcomes, including gestational age and asymmetric fetal growth. Pb and depression can cumulatively influence birth outcomes and epigenetic mechanisms, which may lay the foundation for later health risk. As toxicants and social adversities commonly co-occur, research should consider the life course consequences of these interconnected exposures.

Biologic and Targeted Synthetic DMARD Utilization in the United States: Adelphi Real World Disease Specific Programme for Rheumatoid Arthritis.

INTRODUCTION: In patients with inadequate response or intolerance to first biologic disease-modifying antirheumatic drug (bDMARD), guidelines recommend switching to an agent of different mechanism of action or to another bDMARD. However, the reasons behind switching between bDMARD/targeted synthetic (ts)DMARD are not well documented in many studies. The objective of this study was to assess the rheumatologists' perceptions and behaviors towards choice of initial b/tsDMARD treatment and reasons for switching between bDMARDs/tsDMARDs, in the context of present treatment patterns. METHODS: This was a retrospective analysis of data collected from the 12th Adelphi Real World Disease Specific Programme for rheumatoid arthritis (RA). Qualified rheumatologists involved in treatment decision-making for ≥ 10 patients a month completed patient record forms (PRFs). Patients aged ≥ 18 years with RA diagnosis and receiving bDMARD/tsDMARD were included. The outcomes assessed were proportion of patients receiving bDMARD/tsDMARD at molecule and class levels; rheumatologist-reported reasons for choice of therapy; proportion of patients who switched bDMARDs/tsDMARDs; and rheumatologist-reported reasons for switching therapies. RESULTS: Eighty-six rheumatologists completed PRFs for 1027 patients. Of these, 621 were receiving bDMARD/tsDMARD at data collection. The majority (73%) of patients received first-line bDMARD/tsDMARD, and at first-line, 68% received a tumor necrosis factor inhibitor (TNFi) and 21% received a Janus kinase inhibitor (JAKi). The response option of strong overall efficacy was the primary reason for selecting first-line and second-line bDMARD/tsDMARD. A total of 163 patients had switched from first-line b/tsDMARD to second-line b/tsDMARD therapy. Of these, 44, 28, and 17% had switched from TNFi to another TNFi, TNFi to non-TNF biologic, and TNFi to JAKi, respectively. Lack of efficacy and worsening disease were the most frequent reasons for switching therapies. CONCLUSIONS: TNFis remain the most prescribed b/tsDMARD for first-line and second-line treatments. Strong overall efficacy was the primary reason for selecting therapy and loss of efficacy was the primary reason for switching therapy.

Real world effectiveness and satisfaction with secukinumab in the treatment of patients with psoriatic arthritis: a population survey in five European countries.

OBJECTIVES: To describe the effectiveness of secukinumab in the treatment of psoriatic arthritis (PsA) and associated physician satisfaction with secukinumab treatment, in routine clinical practice across five European countries. METHODS: A retrospective analysis of PsA patients receiving secukinumab for ≥4 months in France, Germany, Italy, Spain and the UK from March to December 2018. Data based on physician-completed questionnaires at initiation of treatment and at the data collection consultation were collected and used to assess effectiveness. RESULTS: 572 PsA patients with a mean age of 47.9 years, 57.0% were male, with 5.6% of patients with mild, 55.2% with moderate and 38.1% severe PsA prior to treatment initiation were included. 33.0% of patients received a dosage of 150 mg and 67.0% a dosage of 300 mg secukinumab. Around 84% of patients received secukinumab for 6 months or longer. Symptoms seen at current assessment in over 20% of patients were tender or swollen joints or psoriatic skin lesions. Between initiation of treatment and the current consultation, improvements in skin, joint and overall severity were reported. Physician satisfaction with secukinumab's ability to control disease was very high during the study period, greater than 90%, and was seen irrespective of disease severity at initiation, prior biologic use, treatment duration, time since diagnosis or onset of symptoms, treatment history, and BMI. CONCLUSION: Physicians were satisfied with the ability of secukinumab to control disease and it was effective in the treatment of PsA patients in routine clinical settings.

Prenatal Exposure to Favorable Social and Environmental Neighborhood Conditions Is Associated with Healthy Pregnancy and Infant Outcomes.

Neighborhood and individual level risks commonly co-occur for pregnant women and may cumulatively contribute to birth outcomes. Moreover, the relationship between favorable social and environmental neighborhood conditions and perinatal outcomes has been understudied. This study considered the accumulated impact of prenatal exposure to positive neighborhood social, environmental, and educational conditions in relation to maternal health during pregnancy and birth size outcomes. In a prospective study of a multi-ethnic and socioeconomically diverse cohort (n = 239) of pregnant women and their infants, neighborhoods were characterized by the Child Opportunity Index (COI), a census-tract composite indicator representing favorable social, environmental, and educational community conditions. Adjusted generalized estimating equations showed that favorable neighborhood conditions promoted the growth of longer and heavier infant bodies, and reduced the risk of intrauterine growth restriction. The associations were stronger for female versus male infants, though not significantly different. Moreover, COI was associated with better maternal mental health and diet during pregnancy; diet significantly mediated the association between COI and birth size outcomes. This study underscores the importance of considering the accumulated benefit of neighborhood assets for maternal and infant health. Interventions that capitalizes on the full range of contextual assets in which mothers live may promote pregnancy health and fetal growth.

Cross-walk of the Assessment of Spondyloarthritis International Society Health Index and Ankylosing Spondylitis Quality of Life Scores in Ankylosing Spondylitis and Non-radiographic Axial Spondyloarthritis Patients.

INTRODUCTION: Axial spondyloarthritis (axSpA) is a chronic rheumatic disease affecting the spine and sacroiliac joints, encompassing both ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA) patients. Patient quality of life (QoL) is assessed using the Ankylosing Spondylitis Quality of Life (ASQoL) (disease-specific measure) and the Assessment of SpondyloArthritis International Society Health Index (ASAS HI) (disease-specific measure). Both ASQoL and ASAS HI have similar parameters and scoring ranges, however, their performance relative to each other is unknown. We conducted a cross-walk analysis of the ASAS HI to the ASQoL in AS and nr-axSpA patients. METHODS: A cross-sectional survey using the Adelphi axSpA Disease Specific Programme™, conducted with rheumatologists and their consulting AS and nr-axSpA patients in the United States, was undertaken between Jun and Aug 2018. Rheumatologists provided confirmed diagnoses of AS and nr-axSpA alongside patients' demographic and clinical characteristics. Patients reported quality-of-life measures using the validated ASAS HI and ASQoL questionnaires. Model performance was assessed by comparing root-mean squared error (RMSE) from tenfold cross-validation to determine the best mapping from ASAS HI to ASQoL, and vice versa. RMSE was calculated overall, and for lower, middle and upper thirds of the predicted scale. RESULTS: Data from 283 AS and 274 nr-axSpA patients were analyzed. Predicting ASAS HI using ASQoL values, the best model was non-parametric local linear regression, with overall RMSE of 1.851. Predicting ASQoL using ASAS HI values, the best model also used non-parametric local-linear regression, with overall RMSE of 2.254. In predicting ASAS HI and ASQoL, models performed better in predicting lower values in the predicted scale (RMSE 1.597, 1.871, 2.871 across thirds for ASAS HI; and 1.719, 2.577, 3.140 for ASQoL). CONCLUSIONS: Results present a scoring algorithm for cross-walking the ASAS HI to the ASQoL and vice versa, with the approach enabling comparisons to be made across studies.

Comparing symptoms, treatment patterns, and quality of life of ankylosing spondylitis and non-radiographic axial spondyloarthritis patients in the USA: findings from a patient and rheumatologist Survey.

OBJECTIVES: The aim of this study was to compare the symptoms, treatment patterns, and quality of life (QoL) of ankylosing spondylitis (AS) patients to non-radiographic axial spondyloarthritis (nr-axSpA) patients in the USA. METHOD: A cross-sectional survey was conducted with rheumatologists and their consulting patients in the USA from June through August 2018. Patients who had a rheumatologist confirmed diagnosis of AS and nr-axSpA were eligible to participate. Patient demographics, symptoms, and medication use were reported by the rheumatologist, while work disability and QoL measures were reported by the patient. Patient demographics, symptoms, QoL and treatment patterns of AS and nr-axSpA patients were compared using parametric tests and non-parametric tests when appropriate. RESULTS: A total of 515 AS patients and 495 nr-axSpA patients were included in this analysis. A higher proportion of AS patients were male (p < 0.001), older (p = 0.014), and more likely to be prescribed a biologic (p < 0.0001). On average, AS patients experienced slightly more symptoms at diagnosis (p = 0.023); however, nr-axSpA patients were more likely to experience enthesitis (p = 0.048) and synovitis (p = 0.003). Patient reported outcomes such as the ASAS Health Index (p = 0.171), ASQoL (p = 0.296), BASDAI (p = 0.124), and WPAI (p = 0.183) were similar between AS and nr-axSpA patients after adjusting for confounding variables such as medication use. CONCLUSIONS: AS and nr-axSpA patients share the same clinical features. The burden of the disease, as assessed by QoL measurements, is also similar in AS and nr-axSpA patients; however, despite these similarities, patients with nr-axSpA are less likely to be treated with a biologic. KEY POINTS: • Ankylosing spondylitis and non • radiographic axial spondyloarthritis patients share similar clinical features and burden of disease. • Quality of life is similar among ankylosing spondylitis and non • radiographic axial spondyloarthritis after adjusting for current treatment patterns.

Impact of Enthesitis on Psoriatic Arthritis Patient-Reported Outcomes and Physician Satisfaction with Treatment: Data from a Multinational Patient and Physician Survey.

INTRODUCTION: Enthesitis is a core outcome domain assessed in psoriatic arthritis (PsA) clinical trials. Limited evidence describes the impact of enthesitis on patient-reported outcomes (PROs) and physician satisfaction with current treatment options. The objective of this analysis is to characterize the impact of enthesitis on PROs and physician satisfaction with currently available treatment in clinical practice settings. METHODS: Cross-sectional survey of rheumatologists, dermatologists, and their consulting patients with PsA in Australia, Canada, European Union (EU5), and the USA conducted in 2018. Physicians assessed current presence and severity of enthesitis, overall disease severity, other symptoms experienced, and their satisfaction with the current treatment. PsA participant self-reported data included current pain level, EQ5D, Psoriatic Arthritis Impact of Disease (PsAID12), Health Assessment Questionnaire Disability Index (HAQ-DI), and Work Productivity and Activity Impairment Index (WPAI-SHP). Bivariate descriptive analyses were conducted to describe features and outcomes in participants with and without enthesitis. RESULTS: Rheumatologists (454) and dermatologists (238) provided information for 3157 participants with PsA. Mean participant age was 49.2 years, and 45.9% were female. Enthesitis was present currently in 6.5% (205) of participants with PsA. Those with enthesitis had worse overall disease severity compared to those without enthesitis (12.2% vs 2.2% severe) and had more extraarticular manifestations, including nail psoriasis, dactylitis, and sacroiliitis. Enthesitis was associated with more pain, worse quality of life (QoL), increased disability, and a negative impact on work. Participants with enthesitis had higher NSAIDs and opioid pain medication use but similar biologic use. Physicians were significantly less satisfied with current PsA treatment in participants with enthesitis versus without enthesitis. CONCLUSIONS: Participants with psoriatic arthritis with enthesitis experienced significantly higher disease burden than those without enthesitis but were not more likely to receive advanced therapies. Physicians were significantly more dissatisfied with treatment in patients with enthesitis than in those without it.

Type of Track and Trigger system and incidence of in-hospital cardiac arrest: an observational registry-based study.

BACKGROUND: Failure to recognise and respond to patient deterioration on hospital wards is a common cause of healthcare-related harm. If patients are not rescued and suffer a cardiac arrest as a result then only around 15% will survive. Track and Trigger systems have been introduced into the NHS to improve both identification and response to such patients. This study examines the association between the type of Track & Trigger System (TTS) (National Early Warning Score (NEWS) versus non-NEWS) and the mode of TTS (paper TTS versus electronic TTS) and incidence of in-hospital ward-based cardiac arrests (IHCA) attended by a resuscitation team. METHODS: TTS type and mode was retrospectively collected at hospital level from 106 NHS acute hospitals in England between 2009 to 2015 via an organisational survey. Poisson regression and logistic regression models, adjusted for case-mix, temporal trends and seasonality were used to determine the association between TTS and hospital-level ward-based IHCA and survival rates. RESULTS: The NEWS was introduced in England in 2012 and by 2015, three-fifths of hospitals had adopted it. One fifth of hospitals had instituted an electronic TTS by 2015. Between 2009 and 2015 the incidence of IHCA fell. Introduction or use of NEWS in a hospital was associated with a reduction of 9.4% in the rate of ward-based IHCA compared to non-NEWS systems (incidence rate ratio 0.906, p < 0.001). The use of an electronic TTS was also associated with a reduction of 9.8% in the rate of IHCA compared with paper-based TTS (incidence rate ratio 0.902, p = 0.009). There was no change in hospital survival. CONCLUSIONS: The introduction of standardised TTS and electronic TTS have the potential to reduce ward-based IHCA. This is likely to be via a range of mechanisms from early intervention to institution of treatment limits. The lack of association with survival may reflect the complexity of response to triggering of the afferent arm of the rapid response system.
