Long-term trajectories of ambulatory impairment in multiple sclerosis.

BACKGROUND: Ambulatory impairment is a common and complex manifestation of multiple sclerosis (MS), and longitudinal patterns are not well understood. OBJECTIVE: To characterize longitudinal walking speed trajectories in a general MS patient population and in those with early disease (⩽ 5 years from onset), identify subgroups with similar patterns, and examine associations with individual attributes. METHODS: Using a retrospective cohort study design, latent class growth analysis was applied to longitudinal timed 25-foot walk (T25-FW) data from 7683 MS patients, to determine T25-FW trajectories. Associations were evaluated between trajectory assignment and individual attributes. Analyses were repeated for 2591 patients with early disease. RESULTS: In the general patient population, six trajectories were discerned, ranging from very minimal to very high impairment at baseline, with variability in impairment accrual. The clusters with moderate to very high walking impairment were associated with being female, older and Black American, longer symptom duration, progressive course, and depressive symptoms. In the early disease subset, eight trajectories were discerned that included two subgroups that rapidly accrued impairment. CONCLUSION: We identified novel subgroups of MS patients will distinct long-term T25-FW trajectories. These results underscore that socially disadvantaged and economically marginalized MS patients are the most vulnerable for severe ambulatory impairment.

Characterizing fatigue phenotypes with other symptoms and clinically relevant outcomes among people with multiple sclerosis.

PURPOSE: Fatigue is a common symptom of multiple sclerosis (MS) and can adversely affect all aspect of quality of life. The etiology of fatigue remains unclear, and its treatments are suboptimal. Characterizing the phenotypes of fatigued persons with MS may help advance research on fatigue's etiology and identify ways to personalize fatigue interventions to improve quality of life. The purpose of this study was to identify fatigue phenotypes; examine phenotype stability overtime; and characterize phenotypes by health and function, social and environmental determinants, psychosocial factors, and engagement in healthy behaviors. METHODS: We conducted a longitudinal study over a 3-month period with 289 fatigued participants with MS. To identify fatigue phenotypes and determine transition probabilities, we used latent profile and transition analyses with valid self-report measures of mental and physical fatigue severity, the mental and physical impact of fatigue, depression, anxiety, and sleep quality. We used ANOVAs and effect sizes to characterize differences among phenotypes. RESULTS: The best fitting model included six subgroups of participants: Mild Phenotype, Mild-to-Moderate Phenotype, Moderate-to-Severe Phenotype, Severe Phenotype, Fatigue-dominant Phenotype, and Mental Health-dominant Phenotype. The transition analysis indicated that phenotypic membership was highly stable. Variables with a large eta squared effect size included environmental barriers, self-efficacy, and fatigue catastrophizing. CONCLUSION: These results indicate that the magnitude of fatigue experienced may be more important to consider than the type of fatigue when characterizing fatigue phenotypes. Future research should explore whether tailoring interventions to environmental barriers, self-efficacy, and fatigue catastrophizing reduce the likelihood of transitioning to a more severe phenotype.

Food Insecurity Trajectories in the US During the First Year of the COVID-19 Pandemic.

INTRODUCTION: The objective of this study was to characterize population-level trajectories in the probability of food insecurity in the US during the first year of the COVID-19 pandemic and to examine sociodemographic correlates associated with identified trajectories. METHODS: We analyzed data from the Understanding America Study survey, a nationally representative panel (N = 7,944) that assessed food insecurity every 2 weeks from April 1, 2020, through March 16, 2021. We used latent class growth analysis to determine patterns (or classes) of pandemic-related food insecurity during a 1-year period. RESULTS: We found 10 classes of trajectories of food insecurity, including 1 class of consistent food security (64.7%), 1 class of consistent food insecurity (3.4%), 5 classes of decreasing food insecurity (15.8%), 2 classes of increasing food insecurity (4.6%), and 1 class of stable but elevated food insecurity (11.6%). Relative to the class that remained food secure, other classes were younger, had a greater proportion of women, and tended to identify with a racial or ethnic minority group. CONCLUSION: We found heterogeneous longitudinal patterns in the development, resolution, or persistence of food insecurity during the first year of the COVID-19 pandemic. Experiences of food insecurity were highly variable across the US population, with one-third experiencing some form of food insecurity risk. Findings have implications for identifying population groups who are at increased risk of food insecurity and related health disparities beyond the first year of the pandemic.

Smokers with MS have greater decrements in quality of life and disability than non-smokers.

BACKGROUND: Tobacco smoke plays a pathogenic role in multiple sclerosis (MS) and may accelerate disease progression, yet, some people with MS continue to smoke after disease onset. The average smoker reports diminished health-related quality of life (HRQOL) across many populations. OBJECTIVES: To describe the relationships between smoking status and HRQOL, disease activity, and global disability in a US population with MS. METHODS: We compared smokers to non-smokers in 950 responders to the Spring 2014 update survey completed by North American Research Committee on Multiple Sclerosis (NARCOMS) registry participants. HRQOL was assessed using Short Form-12 version 2 (SF-12v2), disease activity was investigated using eight Performance Scales (PS) and three Functionality Scales (FS). Global disability was evaluated using Patient Determined Disease Steps (PDDS) and an item response theory (IRT) summed score based on the PS and FS. RESULTS: Smokers had lower HRQOL ( p < 0.0001), reported more disease activity ( p < 0.05) and greater deficits in all PS and FS ( p = 6 × 10-7 to 0.05), except mobility. Smokers and non-smokers did not differ by PDDS but had substantially greater IRT global disability ( p = 2 × 10-7). CONCLUSION: Active smoking is meaningfully associated with deficits across multiple domains in people with MS and adds to the growing literature of the need for MS-tailored smoking cessation programs.

Contralaterally Controlled Functional Electrical Stimulation Improves Hand Dexterity in Chronic Hemiparesis: A Randomized Trial.

BACKGROUND AND PURPOSE: It is unknown whether one method of neuromuscular electrical stimulation for poststroke upper limb rehabilitation is more effective than another. Our aim was to compare the effects of contralaterally controlled functional electrical stimulation (CCFES) with cyclic neuromuscular electrical stimulation (cNMES). METHODS: Stroke patients with chronic (>6 months) moderate to severe upper extremity hemiparesis (n=80) were randomized to receive 10 sessions/wk of CCFES- or cNMES-assisted hand opening exercise at home plus 20 sessions of functional task practice in the laboratory for 12 weeks. The task practice for the CCFES group was stimulation assisted. The primary outcome was change in Box and Block Test (BBT) score at 6 months post treatment. Upper extremity Fugl-Meyer and Arm Motor Abilities Test were also measured. RESULTS: At 6 months post treatment, the CCFES group had greater improvement on the BBT, 4.6 (95% confidence interval [CI], 2.2-7.0), than the cNMES group, 1.8 (95% CI, 0.6-3.0), between-group difference of 2.8 (95% CI, 0.1-5.5), P=0.045. No significant between-group difference was found for the upper extremity Fugl-Meyer (P=0.888) or Arm Motor Abilities Test (P=0.096). Participants who had the largest improvements on BBT were <2 years post stroke with moderate (ie, not severe) hand impairment at baseline. Among these, the 6-month post-treatment BBT gains of the CCFES group, 9.6 (95% CI, 5.6-13.6), were greater than those of the cNMES group, 4.1 (95% CI, 1.7-6.5), between-group difference of 5.5 (95% CI, 0.8-10.2), P=0.023. CONCLUSIONS: CCFES improved hand dexterity more than cNMES in chronic stroke survivors. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT00891319.

Effects of Patient Centered Interventions on Persistent Urinary Incontinence after Prostate Cancer Treatment: A Randomized, Controlled Trial.

PURPOSE: We examined whether an intervention combining pelvic floor muscle exercise and symptom self-management would improve urinary continence and quality of life in patients with prostate cancer. MATERIALS AND METHODS: In a randomized, controlled, longitudinal clinical trial 279 patients with prostate cancer with persistent urinary incontinence were randomized to 1 of 3 groups, including biofeedback pelvic floor muscle exercise plus a support group, the biofeedback exercise plus telephone contact and usual care without intervention. The biofeedback plus support and plus telephone groups received 1 session of biofeedback assisted exercise and 6 biweekly sessions of problem solving therapy. This delivered symptom management skills through a peer support group or telephone contacts for 3 months. All subjects were assessed in blinded fashion at baseline, and 3 and 6 months for urinary leakage frequency, leakage amount and disease specific quality of life. RESULTS: A total of 244 subjects completed the study. The biofeedback plus support and biofeedback plus telephone groups had a lower frequency of daily urinary leakage than the group with usual care without intervention at 3 months (p=0.019 and p≤0.001, respectively) but not at 6 months. The biofeedback plus support group but not the biofeedback plus telephone group had 13.3 gm lower leakage at 6 months than the usual care group (p=0.003). Overall the biofeedback plus support and plus telephone groups reported less symptom severity (p≤0.001) and fewer incontinence problems (p≤0.01) than the usual care group at 6 months. CONCLUSIONS: Study findings show that pelvic floor muscle exercise practice plus symptom self-management in a peer support setting can significantly improve urinary continence and quality of life in patients with prostate cancer.

A tutorial on structural equation modeling for analysis of overlapping symptoms in co-occurring conditions using MPlus.

Structural equation modeling (SEM) is a very general approach to analyzing data in the presence of measurement error and complex causal relationships. In this tutorial, we describe SEM, with special attention to exploratory factor analysis, confirmatory factor analysis, and multiple indicator multiple cause modeling. The tutorial is motivated by a problem of symptom overlap routinely faced by clinicians and researchers, in which symptoms or test results are common to two or more co-occurring conditions. As a result of such overlap, diagnoses, treatment decisions, and inferences about the effectiveness of treatments for these conditions can be biased. This problem is further complicated by increasing reliance on patient-reported outcomes, which introduces systematic error based on an individual's interpretation of a test questionnaire. SEM provides flexibility in handling this type of differential item functioning and disentangling the overlap. Scales and scoring approaches can be revised to be free of this overlap, leading to better care. This tutorial uses an example of depression screening in multiple sclerosis patients in which depressive symptoms overlap with other symptoms, such as fatigue, cognitive impairment, and functional impairment. Details of how MPlus (Muthén & Muthén, Los Angeles, CA, USA) software can be used to address the symptom overlap problem, including data requirements, code and output are described in this tutorial.

A retrospective cohort study of factors relating to the longitudinal change in birth weight.

BACKGROUND: Recent reports have shown a decrease in birth weight, a change from prior steady increases. Therefore we sought to describe the demographic and anthropometric changes in singleton term fetal growth. METHODS: This was a retrospective cohort analysis of term singleton deliveries (37-42 weeks) from January 1, 1995 to January 1, 2010 at a single tertiary obstetric unit. We included all 43,217 neonates from term, singleton, non-anomalous pregnancies. Data were grouped into five 3-year intervals. Mean and median birth weight (BW), birth length (BL), and Ponderal Index (PI) were estimated by year, race and gestational age. Our primary outcome was change in BW over time. The secondary outcomes were changes in BL and PI over time. RESULTS: Mean and median BW decreased by 72 and 70 g respectively (p < 0.0001) over the 15 year period while BL also significantly decreased by 1.0 cm (P < 0.001). This contributed to an increase in the neonatal PI by 0.11 kg/m(3) (P < 0.001). Mean gestational age at delivery decreased while maternal BMI at delivery, hypertension, diabetes, and African American race increased. Adjusting for gestational age, race, infant sex, maternal BMI, smoking, diabetes, hypertension, and parity, year of birth contributed 0.1 % to the variance (-1.7 g/year; 26 g) of BW, 1.8% (-0.06 cm/year; 0.9 cm) of BL, and 0.7% (+0.008 kg/m(3)/year; 0.12 kg/m(3)) of PI. These findings were independent of the proportional change in race or gestational age. CONCLUSIONS: We observed a crude decrease in mean BW of 72 g and BL of 1 cm over 15 years. Furthermore, once controlling for gestational age, race, infant sex, maternal BMI, smoking, diabetes, hypertension, and parity, we identified that increasing year of birth was associated with a decrease in BW of 1.7 g/year. The significant increase in PI, despite the decrease in BW emphasizes the limitation of using birth weight alone to define changes in fetal growth.

Disentangling Multiple Sclerosis and depression: an adjusted depression screening score for patient-centered care.

Screening for depression can be challenging in Multiple Sclerosis (MS) patients due to the overlap of depressive symptoms with other symptoms, such as fatigue, cognitive impairment and functional impairment, for MS patients. The aim of this study was to understand these overlapping symptoms and subsequently develop an adjusted depression screening tool for better clinical assessment of depressive symptoms in MS patients. We evaluated 3,507 MS patients with a self-reported depression screening (PHQ-9) score using a multiple indicator multiple cause modeling approach. Our models showed significant differential item functioning effects denoting significant overlap of depressive symptoms with all MS symptoms under study and good model fit. The magnitude of the overlap was especially large for fatigue. Adjusted depression screening scales were formed based on factor scores and loadings that will allow clinicians to understand the depressive symptoms separate from other symptoms for MS patients for improved patient care.

Percutaneous peripheral nerve stimulation for chronic pain in subacromial impingement syndrome: a case series.

OBJECTIVE: The objective of this study was to determine the effect of peripheral nerve stimulation (PNS) on pain reduction for those with refractory subacromial impingement syndrome (SIS) and to evaluate the association with reduced disability, impairment, and safety. Our hypotheses are that PNS will be associated with a reduction in pain, impairment and disability, and improvement in quality of life while demonstrating safety. MATERIAL AND METHODS: Adults with shoulder pain of at least six months duration were recruited for a three-week treatment of percutaneous PNS applied through a percutaneous electrode to the axillary motor points of the deltoid muscle. Subjects were followed for 12 weeks after treatment. The primary outcome was the worst pain in the last week, and secondary outcomes included pain interference, the Disabilities of the Arm, Shoulder, and Hand questionnaire, shoulder abduction range of motion, and safety. Analysis was with a linear mixed model. RESULTS: Ten subjects were recruited. Longitudinal analysis demonstrated significant reduction in pain relative to baseline (F(1, 66) = 12.9, p < 0.01). After correcting for multiple comparisons, there were significant reductions at explantation and all follow-up time points when compared with baseline. There were also significant improvements in pain interference (F(1,65) = 15.0, p < 0.01), the Disabilities of the Arm, Shoulder, and Hand questionnaire (F(1,35) = 7.0, p = 0.01), and shoulder abduction range of motion (F(1,35) = 6.3, p = 0.02). CONCLUSION: Intramuscular PNS for chronic shoulder pain due to SIS is a safe treatment associated with pain reduction, lower pain interference with activities of daily living, reduced disability, and improved shoulder abduction. Pain reduction is maintained for at least 12 weeks after treatment.

A person-centered approach to characterizing longitudinal ambulatory impairment in Parkinson's disease.

Loss of ambulation is common and highly variable in Parkinson's disease (PD), and poorly understood from the perspectives of those with PD. Gaining insights to the anticipated perceived trajectories and their drivers, will facilitate patient-centered care. Latent class growth analysis, a person-centered mixture modelling approach, was applied to 16,863 people with PD stratified by early (N = 8612; < 3 years), mid (N = 6181; 3-10 years) and later (N = 2070; > 10 years) disease to discern clusters with similar longitudinal patterns of self-reported walking difficulty, measured by EuroQoL 5D-5L that is validated for use in PD. There were four clusters in early and mid-disease strata, with a fifth identified in later disease. Trajectories ranged from none to moderate walking difficulty, with small clusters with severe problems. The percentage of subjects with moderate (early = 17.5%, mid = 26.4%, later = 32.5%) and severe (early = 3.8%, mid = 7.4%, later = 15.4%) walking difficulty at baseline increased across disease duration groups. The trajectories tended to be stable with variability in moderate and severe groups. Across strata, clusters with moderate to severe problems were associated with more severe impairment, depression, anxiety, arthritis, higher BMI, lower income, and lower education, but no consistent race or gender differences. The findings reveal distinct longitudinal patterns in perceived difficulties in walking in PD.

Longitudinal experience of food insecurity & cigarette use in the early COVID-19 Pandemic, United States.

Food insecurity is associated with cigarette smoking, yet little is known about how variability in the experience of food insecurity may relate to patterns of cigarette use. We sought to examine patterns of food insecurity and cigarette use during the COVID-19 pandemic (April 2020-March 2021). We analyzed longitudinal survey data from a nationally representative panel of adults in the United States (N = 7,880) from the Understanding Coronavirus in America Study. The primary independent variable was ten trajectories of food insecurity. Our dependent variable was past 7-day cigarette use (count of days used cigarettes). Poisson regression using generalized estimating equations was run controlling for key covariates. The prevalence of cigarette use on at least one day in the past week was lowest (17.5 %) for those who Remained Food Secure, and highest (57.9 %) among those who Became Fully Food Insecure, a group characterized by having high probability of becoming food insecure during the study period. Among those who reported at least one day of cigarette use in the past week, fewer than half (40.1 %) reported sustained use across all waves of the study. Those who Became Fully Food Insecure had an incidence rate ratio (IRR) of 1.73 (95 % CI: 1.18, 2.54) compared to those who Remained Food Secure with respect to number of smoking days. While different patterns of food insecurity are related to cigarette smoking at the population level, these results highlight that food insecurity, a key social need, may represent a novel strategy for informing reduction of tobacco use disparities.

Modeling the Impact of Decreasing Waiting Period Length for Medicaid Sterilization: A Multi-Site Cohort Study.

OBJECTIVE: To evaluate the impact of length of the Medicaid sterilization waiting period and postpartum permanent contraception fulfillment. STUDY DESIGN: Simulations from a retrospective cohort study estimating the potential increase in permanent contraception within 365 days of delivery RESULTS: In our sample of 2,076 patients, 61% achieved permanent contraception with the current waiting period of 30 days. With the waiting period hypothetically reduced to 15, 3, 1, and 0 days, 62.9%, 63.7%, 64.5%, and 75% patients, respectively, would have achieved permanent contraception. CONCLUSIONS: As potential Medicaid sterilization policy revisions are considered, understanding the impact on fulfillment rates is critical.

Common Social and Health Disparities Contribute to Racial Differences in Ambulatory Impairment in Multiple Sclerosis.

BACKGROUND: We previously reported more rapid accrual of ambulatory impairments in Black compared to White individuals with relapsing remitting multiple sclerosis (RRMS) and higher body mass index (BMI). Hypertension and lower neighborhood socioeconomic status (SES) were associated with greater impairment, irrespective of race. We hypothesize that these common social and health inequities may explain a substantial portion of the racial differences in ambulation in American individuals with RRMS. METHODS: Causal mediation analyses investigated baseline and change-over-time mediators of ambulatory impairment differences between 1795 Black and White individuals with RRMS using a retrospective cohort study comprised of electronic health record data from 8491 clinical encounters between 2008 and 2015 where Timed 25-Foot Walk (T25FW) speeds without assistive devices were recorded. The hypothesis was that BMI, neighborhood SES, and hypertension were possible mediators. RESULTS: At baseline, Black individuals with RRMS (n = 175) had significantly slower T25FW speeds (5.78 vs 5.27 ft/s), higher BMI, a higher prevalence of hypertension, and they were more likely to live in lower-income neighborhoods than White individuals (n = 1,620). At baseline, a significant proportion (33.7%; 95% CI, 18.9%-59.4%) of the T25FW difference between Black and White individuals was indirectly due to a higher BMI (12.5%), hypertension burden (9.5%), and living in lower-income neighborhoods (11.2%). Once baseline mediation relationships were accounted for, there were no significant longitudinal mediation relationships. CONCLUSIONS: The findings implicate social and health disparities as prominent drivers of ambulatory differences between Black and White individuals with RRMS, suggesting that wellness and health promotion are essential components of MS care, particularly for Black individuals.

Neighbourhood socioeconomic position, prenatal care and fulfilment of postpartum permanent contraception: Findings from a multisite cohort study.

Introduction: Research suggests neighbourhood socioeconomic vulnerability is negatively associated with women's likelihood of receiving adequate prenatal care and achieving desired postpartum permanent contraception. Receiving adequate prenatal care is linked to a greater likelihood of achieving desired permanent contraception, and access to such care may be critical for women with Medicaid insurance given that the federally mandated Medicaid sterilization consent form must be signed at least 30 days before the procedure. We examined whether adequacy of prenatal care mediates the relationship between neighbourhood socioeconomic position and postpartum permanent contraception fulfilment, and examined moderation of relationships by insurance type. Methods: This secondary analysis of a retrospective cohort study examined 3012 Medicaid or privately insured individuals whose contraceptive plan at postpartum discharge was permanent contraception. Path analysis estimated relationships between neighbourhood socioeconomic position (economic hardship and inequality, financial strength and educational attainment) and permanent contraception fulfilment by hospital discharge, directly and indirectly through adequacy of prenatal care. Multigroup testing examined moderation by insurance type. Results: After adjusting for age, parity, weeks of gestation at delivery, mode of delivery, race, ethnicity, marital status and body mass index, having adequate prenatal care predicted achieving desired sterilization at discharge (ß = 0.065, 95% confidence interval [CI]: 0.011, 0.117). Living in neighbourhoods with less economic hardship (indirect effect -0.007, 95% CI: -0.015, -0.001), less financial strength (indirect effect -0.016, 95% CI: -0.030, -0.002) and greater educational attainment (indirect effect 0.012, 95% CI: 0.002, 0.023) predicted adequate prenatal care, in turn predicting achievement of permanent contraception by discharge. Insurance status conditioned some of these relationships. Conclusion: Contact with the healthcare system via prenatal care may be a mechanism by which neighbourhood socioeconomic disadvantage affects permanent contraception fulfilment, particularly for patients with Medicaid. To promote reproductive autonomy and healthcare equity, future inquiry and policy might closely examine how neighbourhood social and economic characteristics interact with Medicaid mandates.

Randomized controlled trial of surface peroneal nerve stimulation for motor relearning in lower limb hemiparesis.

OBJECTIVE: To compare the motor relearning effect of a surface peroneal nerve stimulator (PNS) versus usual care on lower limb motor impairment, activity limitation, and quality of life among chronic stroke survivors. DESIGN: Single-blinded randomized controlled trial. SETTING: Teaching hospital of academic medical center. PARTICIPANTS: Chronic stroke survivors (N=110; >12wk poststroke) with unilateral hemiparesis and dorsiflexion strength of ≤4/5 on the Medical Research Council scale. INTERVENTIONS: Subjects were stratified by motor impairment level and then randomly assigned to ambulation training with either a surface PNS device or usual care (ankle-foot orthosis or no device) intervention. Subjects were treated for 12 weeks and followed up for 6 months posttreatment. MAIN OUTCOME MEASURES: Lower limb portion of the Fugl-Meyer (FM) Assessment (motor impairment), the modified Emory Functional Ambulation Profile (mEFAP) performed without a device (functional ambulation), and the Stroke Specific Quality of Life (SSQOL) scale. RESULTS: There was no significant treatment group main effect or treatment group by time interaction effect on FM, mEFAP, or SSQOL raw scores (P>.05). The time effect was significant for the 3 raw scores (P<.05). However, when comparing average change scores from baseline (t1) to end of treatment (t2, 12wk), and at 12 weeks (t3) and 24 weeks (t4) after end of treatment, significant differences were noted only for the mEFAP and SSQOL scores. The change in the average scores for both mEFAP and SSQOL occurred between t1 and t2, followed by relative stability thereafter. CONCLUSIONS: There was no evidence of a motor relearning effect on lower limb motor impairment in either the PNS or usual-care groups. However, both the PNS and usual-care groups demonstrated significant improvements in functional mobility and quality of life during the treatment period, which were maintained at 6-month follow-up.

A new method for classifying prognostic risk factors in lung transplant candidates.

BACKGROUND: Predicting risk of waitlist mortality and subsequent classification of lung transplant candidates has been difficult due to inter-relatedness of risk factors, differential risk across populations, and changes in relationships over time. We developed a clinically intuitive indexing system to simplify mortality risk assessment. METHODS: Scientific Registry of Transplant Recipients data from February 19, 2015, to May 26, 2020 (n = 13,726) were used to estimate 3 constructs. Airway and oxygen function indices were estimated using confirmatory factor analysis and hierarchical clustering was used to derive respiratory support clusters. Cox proportional hazards regression was used to characterize event-free waitlist survival by constructs (3), age, sex, and diagnosis group. Model performance was compared to the Lung Allocation Score/Composite Allocation Score (LAS/CAS). RESULTS: Airway and oxygen function indices were created with substantive factor loadings forced expiratory volume (0.86), forced vital capacity (0.64), partial pressure of carbon dioxide (0.56) and PO2/fraction of inspired oxygen (0.83), partial pressure of oxygen (0.59), and mean pulmonary artery pressure (0.30), respectively. Four respiratory support clusters (C1: as needed O2, C2: continuous O2, C3: continuous O2/positive pressure ventilation (PPV), C4: PPV + extracorporeal membrane oxygenation) were identified. Constructs were used to identify patient profiles. Model area under the receiver operating characteristic curve was 0.85 [0.84, 0.87] compared to the LAS 0.92 [0.91, 0.94] at 4 weeks. Risk predictions were relatively insensitive to airway and oxygen function indices in C1 and C4 but varied across C2 and C3. CONCLUSIONS: Reducing the dimensionality of waitlist mortality risk offers an opportunity to identify clinical phenotypes that are more nuanced and thus more interpretable than current risk assessment provided by the LAS/CAS models.

Study design and protocol for Nourishing Beginnings, an integrated service delivery model addressing food insecurity and social needs of low-income pregnant individuals.

BACKGROUND: Nourishing Beginnings is an integrated referral and service delivery model supporting Medicaid-eligible pregnant individuals by providing increased nutritional food access throughout pregnancy up to three months postpartum, through community health workers (CHW), who simultaneously address and provide support for social service needs of the client. METHODS: To study the impact of possible interventions on food security, the program includes two distinct interventions each paired with traditional CHW services, nutrition educational materials, and provision of basic essential cooking tools. Interventions consist of either bi-weekly home food delivery from the local food bank or bi-weekly financial assistance with healthy food access navigation. The study population consists of 160 pregnant individuals (18 or older,<22 weeks pregnant; 80 per intervention arm) who were referred to a countywide Pathways Community HUB (HUB), a community-based care coordination network that uses an evidence-based model to connect at-risk individuals to resources that address medical, social, economic, and behavioral health needs. Key data collection occurs at baseline, eight weeks after intervention begins, near delivery (36-38 weeks gestation), and three months postpartum. Intervention groups are compared to each other as well as against HUB historical controls and a concurrent matched sample from local Medicaid data. CONCLUSION: The goal of Nourishing Beginnings is to improve long-term health outcomes (i.e., maternal and infant) both directly and mediated through a set of proximal outcomes, including prenatal care, food security, diet and nutrition, reported race discrimination and psychosocial factors including depression, stress, healthy eating self-efficacy, and social support. Clinical Trials #: NCT05341960.

Medicaid and Fulfillment of Postpartum Permanent Contraception Requests.

OBJECTIVE: To evaluate the association between Medicaid insurance and fulfillment of postpartum permanent contraception requests. METHODS: We conducted a retrospective cohort study of 43,915 patients across four study sites in four states, of whom 3,013 (7.1%) had a documented contraceptive plan of permanent contraception at the time of postpartum discharge and either Medicaid insurance or private insurance. Our primary outcome was permanent contraception fulfillment before hospital discharge; we compared individuals with private insurance with individuals with Medicaid insurance. Secondary outcomes were permanent contraception fulfillment within 42 and 365 days of delivery, as well as the rate of subsequent pregnancy after nonfulfillment. Bivariable and multivariable logistic regression analyses were used. RESULTS: Patients with Medicaid insurance (1,096/2,076, 52.8%), compared with those with private insurance (663/937, 70.8%), were less likely to receive desired permanent contraception before hospital discharge (P≤.001). After adjustment for age, parity, weeks of gestation, mode of delivery, adequacy of prenatal care, race, ethnicity, marital status, and body mass index, private insurance status was associated with higher odds of fulfillment at discharge (adjusted odds ratio [aOR] 1.48, 95% CI 1.17-1.87) and 42 days (aOR 1.43, 95% CI 1.13-1.80) and 365 days (aOR 1.36, 95% CI 1.08-1.71) postpartum. Of the 980 patients with Medicaid insurance who did not receive postpartum permanent contraception, 42.2% had valid Medicaid sterilization consent forms at the time of delivery. CONCLUSION: Differences in fulfillment rates of postpartum permanent contraception are observable between patients with Medicaid insurance and patients with private insurance after adjustment for clinical and demographic factors. The disparities associated with the federally mandated Medicaid sterilization consent form and waiting period necessitate policy reassessment to promote reproductive autonomy and to ensure equity.
