Background Food insecurity (FI) has been associated with an increased atherosclerotic cardiovascular disease (ASCVD) risk; however, the pathways by which FI leads to worse cardiovascular health are ...unknown. We tested the hypothesis that FI is associated with ASCVD risk through nutritional/anthropometric (eg, worse diet quality and increased weight), psychological/mental health (eg, increased depressive symptoms and risk of substance abuse), and access to care pathways. Methods and Results We conducted a cross-sectional study of adults (aged 40-79 years) using the 2007 to 2016 National Health and Nutrition Examination Survey. Our primary exposure was household FI, and our outcome was 10-year ASCVD risk categorized as low (<5%), borderline (≥5% -<7.5%), intermediate (≥7.5%-<20%), and high risk (≥20%). We used structural equation modeling to evaluate the pathways and multiple mediation analysis to determine direct and indirect effects. Of the 12 429 participants, 2231 (18.0%) reported living in a food-insecure household; 5326 (42.9%) had a low ASCVD risk score, 1402 (11.3%) borderline, 3606 (29.0%) intermediate, and 2095 (16.9%) had a high-risk score. In structural models, we found significant path coefficients between FI and the nutrition/anthropometric (β, 0.130; SE, 0.027;
<0.001), psychological/mental health (β, 0.612; SE, 0.043;
<0.001), and access to care (β, 0.110; SE, 0.036;
=0.002) pathways. We did not find a significant direct effect of FI on ASCVD risk, and the nutrition, psychological, and access to care pathways accounted for 31.6%, 43.9%, and 15.8% of the association, respectively. Conclusions We found that the association between FI and ASCVD risk category was mediated through the nutrition/anthropometric, psychological/mental health, and access to care pathways. Interventions that address all 3 pathways may be needed to mitigate the negative impact of FI on cardiovascular disease.
Background
Research on quality of life (QoL) among women with breast cancer has often examined the impact of coping strategies on QoL. However, the transactional model of stress and coping would ...argue that QoL can impact coping. This reciprocal relationship between QoL and coping has been inadequately studied.
Purpose
This study examined reciprocal relationships over 18 months between QoL and coping (positive and negative coping) among women with breast cancer.
Methods
Three-wave cross-lagged structural equation modelling (SEM) analysis was used over three timepoints post-diagnosis (T1–T3;
N
= 637, 577, 553, respectively).
Results
SEM results revealed a significant reciprocal relationship between negative coping and QoL, indicating that negative coping predicted subsequent QoL, which in turn predicted later negative coping. Although QoL at cancer diagnosis predicted subsequent positive coping, we did not find a reciprocal relation between QoL and positive coping.
Conclusion
Findings expand our knowledge of the relation between QoL and coping by suggesting the reciprocal relationship between negative coping and QoL among women with breast cancer.
Purpose
The Shift and Persist model provides an informative framework to understand how adolescent and young adult (AYA) cancer patients and survivors (ages 15–39) may withstand stress and thrive ...despite adversity. The goal of the present study was to examine the psychometric properties of the Shift and Persist Questionnaire (SPQ) in this population and provide guidelines for interpretation.
Methods
AYA cancer patients and survivors were recruited via an online research panel. Participants reported demographics and health history and completed the SPQ and Patient-Reported Outcome Measurement Information System 29-item profile (PROMIS®-29). We evaluated the structural validity, internal consistency, and construct validity of the SPQ. Minimally important differences (MIDs) were estimated to inform SPQ score interpretation.
Results
572 eligible individuals completed the survey. On average, participants were aged 24 (SD = 7) at evaluation. Of the participants, 43.5% were female, 77.1% were white, and 17.5% were Hispanic (across races). The two-factor structure of the SPQ demonstrated very good structural validity (CFI > 0.95, SRMR < 0.08), and construct validity with PROMIS-29® domains (convergent
R
s = 0.17 to 0.43, divergent
R
s = − 0.11 to − 0.51). Internal consistency was adequate (
ω
= 0.76–0.83). Recommended MIDs were 1 point for the Shift subscale, 1–2 point(s) for the Persist subscale, and 2–3 points for the total SPQ score.
Conclusion
The SPQ is a psychometrically sound measure of skills that contribute to resilience in AYA cancer patients and survivors. MID recommendations enhance the interpretability of the SPQ in this population. Future studies examining shifting and persisting in this population may benefit from administering the SPQ.
Despite defined grades of 1 to 5 for adverse events (AEs) on the basis of Common Terminology Criteria for Adverse Events criteria, mild (G1) and moderate (G2) AEs are often not reported in phase III ...trials. This under-reporting may inhibit our ability to understand patient toxicity burden. We analyze the relationship between the grades of AEs experienced with patient side-effect bother and treatment discontinuation
We analyzed a phase III Eastern Cooperative Oncology Group-American College of Radiology Imaging Network trial with comprehensive AE data. The Likert response Functional Assessment of Cancer Therapy-GP5 item, "I am bothered by side effects of treatment" was used to define side-effect bother. Bayesian mixed models were used to assess the impact of G1 and G2 AE counts on patient side-effect bother and treatment discontinuation. AEs were further analyzed on the basis of symptomatology (symptomatic or asymptomatic). The results are given as odds ratios (ORs) and 95% credible interval (CrI).
Each additional G1 and G2 AEs experienced during a treatment cycle increased the odds of increased self-reported patient side-effect bother by 13% (95% CrI, 1.06 to 1.21) and 35% (95% CrI, 1.19 to 1.54), respectively. Furthermore, only AEs defined as symptomatic were associated with increased side-effect bother, with asymptomatic AEs showing no association regardless of grade. Count of G2 AEs increased the odds of treatment discontinuation by 59% (95% CrI, 1.32 to 1.95), with symptomatic G2 AEs showing a stronger association (OR, 1.75; 95% CrI, 1.28 to 2.39) relative to asymptomatic G2 AEs (OR, 1.45; 95% CrI, 1.12 to 1.89).
Low- and moderate-grade AEs are related to increased odds of increased patient side-effect bother and treatment discontinuation, with symptomatic AEs demonstrating greater magnitude of association than asymptomatic. Our findings suggest that limiting AE capture to grade 3+ misses important contributors to treatment side-effect bother and discontinuation.
Cardiovascular disease (CVD) prevention is practiced concurrently by providers from several specialties. Our goal was to understand providers' preference of specialties in CVD prevention practice and ...the role of preventive cardiologists.
Between 11 October 2021 and 1 March 2022, we surveyed providers from internal medicine, family medicine, endocrinology, and cardiology specialties to examine their preference of specialties in managing various domains of CVD prevention. We examined categorical variables using Chi square test and continuous variables using t or analysis of variance test.
Of 956 invitees, 263 from 21 health systems and 9 states responded. Majority of respondents were women (54.5%), practicing physicians (72.5%), specializing in cardiology (43.6%), and working at academic centers (51.3%). Respondents favored all specialties to prescribe statins (43.2%), ezetimibe (37.8%), sodium-glucose cotransporter-2 (SGLT2) inhibitors (30.5%), and aspirin in primary prevention (36.3%). Only 7.9% and 9.5% selected cardiologists and preventive cardiologists, respectively, to prescribe SGLT2 inhibitors. Most preferred specialists (i.e. cardiology and endocrinology) to manage advanced lipid disorders, refractory hypertension, and premature coronary heart disease. The most common conditions selected for preventive cardiologists to manage were genetic lipid disorders (17%), cardiovascular risk assessment (15%), dyslipidemia (13%), and refractory/resistant hypertension (12%).
For CVD prevention practice, providers favored all specialties to manage common conditions, specialists to manage complex conditions, and preventive cardiologists to manage advanced lipid disorders. Cardiologists were least preferred to prescribe SGLT2 inhibitor. Future research should explore reasons for selected CVD prevention practice preferences to optimize care coordination and for effective use of limited expertise.
Purpose User-generated content on social media sites, such as health-related online forums, offers researchers a tantalizing amount of information, but concerns regarding scientific application of ...such data remain. This paper compares and contrasts symptom cluster patterns derived from messages on a breast cancer forum with those from a symptom checklist completed by breast cancer survivors participating in a research study. Methods Over 50,000 messages generated by 12,991 users of the breast cancer forum on MedHelp.org were transformed into a standard form and examined for the co-occurrence of 25 symptoms. The k-medoid clustering method was used to determine appropriate placement of symptoms within clusters. Findings were compared with a similar analysis of a symptom checklist administered to 653 breast cancer survivors participating in a research study. Results The following clusters were identified using forum data: menopausal/psychological, pain/fatigue, gastrointestinal, and miscellaneous. Study data generated the clusters: menopausal, pain, fatigue/sleep/gastrointestinal, psychological, and increased weight/appetite. Although the clusters are somewhat different, many symptoms that clustered together in the social media analysis remained together in the analysis of the study participants. Density of connections between symptoms, as reflected by rates of co-occurrence and similarity, was higher in the study data. Conclusions The copious amount of data generated by social media outlets can augment findings from traditional data sources. When different sources of information are combined, areas of overlap and discrepancy can be detected, perhaps giving researchers a more accurate picture of reality. However, data derived from social media must be used carefully and with understanding of its limitations.
Abstract Background Physician burnout is rising, especially among academic physicians facing pressures to increase their clinical workload, lead administrative tasks and committees, and be active in ...research. There is a concern this could have downstream effects on learners’ experiences and academic physician’s ability to teach learners on the team. Methods A 29-question RedCap survey was electronically distributed to 54 attending physicians within an academic learning health system who oversaw the General Medicine inpatient teaching services during the 2022–2023 academic year. The aims were to assess this cohort of attending physicians’ experiences, attitudes, and perceptions on their ability to effectively teach learners on the team, feeling valued, contributors to work-life balance and symptoms of burnout, Fisher’s Exact Tests were used for data analysis. Results Response rate was 56%. Attendings splitting time 50% inpatient / 50% outpatient felt that team size and type of admissions model affected their ability to effectively teach learners ( p = 0.022 and p = 0.049). Attendings with protected administrative time felt that non-patient care obligations affected their ability to effectively teach the learners ( p = 0.019). Male attendings and attendings with ≤ 5 years of General Medicine inpatient teaching experience felt less valued by residency leadership ( p = 0.019 and p = 0.026). 80% of attendings experienced emotional exhaustion, and those with > 10 weeks on a General Medicine inpatient teaching service were more likely to experience emotional exhaustion ( p = 0.041). Attendings with > 10 weeks on a General Medicine inpatient teaching service and those who were a primary caregiver were more likely to experience depersonalization ( p = 0.012 and p = 0.031). 57% of attendings had reduced personal achievement. Conclusions Institutions should seek an individual and organizational approach to professional fulfillment. Special attention to these certain groups is warranted to understand how they can be better supported. Further research, such as with focus groups, is needed to address these challenges.
Abstract
Background
Mobility limitation in older adults is common and associated with poor health outcomes and loss of independence. Identification of at-risk individuals remains challenging because ...of time-consuming clinical assessments and limitations of statistical models for dynamic outcomes over time. Therefore, we aimed to develop machine learning models for predicting future mobility limitation in older adults using repeated measures data.
Methods
We used annual assessments over 9 years of follow-up from the Health, Aging, and Body Composition study to model mobility limitation, defined as self-report of any difficulty walking a quarter mile or climbing 10 steps. We considered 46 predictors, including demographics, lifestyle, chronic conditions, and physical function. With a split sample approach, we developed mixed models (generalized linear and Binary Mixed Model forest) using (a) all 46 predictors, (b) a variable selection algorithm, and (c) the top 5 most important predictors. Age was included in all models. Performance was evaluated using area under the receiver operating curve in 2 internal validation data sets.
Results
Area under the receiver operating curve ranged from 0.80 to 0.84 for the models. The most important predictors of mobility limitation were ease of getting up from a chair, gait speed, self-reported health status, body mass index, and depression.
Conclusions
Machine learning models using repeated measures had good performance for identifying older adults at risk of developing mobility limitation. Future studies should evaluate the utility and efficiency of the prediction models as a tool in clinical settings for identifying at-risk older adults who may benefit from interventions aimed to prevent or delay mobility limitation.
Background
Abdominal adhesions are the most common surgical complication and without reliable prophylactics. This study presents a novel rat model for abdominal adhesions and reports pilot results of ...human placental stem cell (hPSC)‐based therapies.
Methods
Forty‐four (n = 44) male Sprague–Dawley rats (250‐350 g) were used in the experiment. Of these, thirty‐eight (n = 38) were included in a preliminary data set to determine a minimum treatment effect. Adhesions were created in a reproducible model to the abdominal wall and between organs. Experimental groups included the control group (Model No Treatment, MNT), Plasmalyte A (Media Alone, MA, 10 mL), hPSC (5 × 106 cells/10 mL Plasmalyte A), hPSC‐CM (hPSC secretome, conditioned media) in 10 mL Plasmalyte A, Seprafilm™ (Baxter, Deerfield, IL), and sham animals (laparotomy only). Treatments were inserted intraperitoneally (IP) and the study period was 14 days post‐operation. Results are reported as the difference between means of an index statistic (AIS, Animal Index Score) and compared by ANOVA with pairwise comparison.
Results
The overall mean AIS was 23 (SD 6.16) for the MNT group with an average of 75% of ischemic buttons involved in abdominal adhesions. Treatment groups MA (mean overall AIS 17.33 SD 6.4), hPSC (mean overall AIS 13.86 SD 5.01), hPSC‐CM (mean overall AIS 13.13 SD 6.15), and Seprafilm (mean overall AIS 13.43 SD 9.11) generated effect sizes of 5.67, 9.14, 9.87, and 9.57 decrease in mean overall AIS, respectively, versus the MNT.
Discussion
The presented rat model and scoring system represent the clinical adhesion disease process. hPSC‐based interventions significantly reduce abdominal adhesions in this pilot dataset.
BACKGROUNDClinical guidelines recommend shared decision-making for treatment of peripheral artery disease (PAD), which requires understanding of patient perspectives and preferences. We conducted a ...focus group study of patients with symptomatic PAD to identify factors important and relevant to treatment choices, and to characterize aspects of the health care process that contribute to positive vs negative experiences apart from the specific treatment(s) received. METHODSParticipants were recruited from an academic medical center over 2 years using a purposeful sampling approach based on a clinical diagnosis of symptomatic PAD (either claudication or chronic limb-threatening ischemia CLTI) confirmed by the abnormal ankle or toe brachial index. Focus groups were led by a nonphysician moderator, consisted of 5 to 12 participants, and were conducted separately for patients with CLTI and claudication. Audio recordings converted to verbatim transcripts were used for qualitative analysis. RESULTSA total of 51 patients (26 with CLTI and 25 with claudication) were enrolled and participated in focus groups. Major themes identified related to treatment preferences and decisions included specific interventions under consideration, the chance of technical success versus failure, anticipated degree of symptom improvement, outcome durability, and risk. Major themes related to the process of care included decision-making input, provider communication and trust, the timeline from diagnosis to definitive treatment, and compartmentalized care (including different venues of care). CONCLUSIONSThe results provide insights into patient preferences, perspectives, and experiences related to PAD treatment. These observations can be used to inform patient-centered approaches to shared decision-making, communication, and assessment of PAD treatment outcomes.
